Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local cleaning apparatus for cleaning a local area by a conventional cleaning control, which does not have a problem of cleaning with an excessive cleaning ability.

[0002]

2. Description of the Related Art First, physical quantities used in the detailed description of the present invention are defined as follows. FIG. 2 is a schematic diagram schematically showing the relationship between the flow of the cleaning water discharged from the cleaning nozzle and the surface to be cleaned.

The area to be cleaned on the surface to be cleaned by local cleaning water: A [m ² ] Instantaneous discharge amount of local cleaning water: Q [m ³ / sec] Water density: ρ _w [kg / m ³ ] Wash water flow velocity v [m / sec] Further, the wash water space volume ratio ρ defined in the present invention is given by: ρ = Q / (A × v) [m ³ / m ³ ] Wash energy is given by: E = ρ _w × Q × v ² = ρ _w × ρ × A × v ³ [W] The spatial average cleaning energy per unit area in the cleaning area A is defined as cleaning intensity, and e = E / A = (ρ _w × Q × v ²⁾ ) / A = ρ _w × ρ × v ³ [W
/ M ² ].

[0004] The basic quality of a local cleaning device is determined by a comfortable cleaning feeling that does not cause problems such as pain or lack of cleaning feeling and an ability to wash local contaminants (appropriate cleaning ability). The instantaneous discharge water amount Q, the local cleaning water flow velocity v, and the cleaning water space volume ratio ρ are determined so that the feeling and the cleaning performance are compatible.

[0005] If the washing area A to be washed with the local washing water is extremely small, the user needs to frequently move his body (buttock) to wash the dirt and the like adhered to the local area. Of these, it cannot be said that adequate cleaning performance has been secured. Therefore, the cleaning capacity increases or decreases with the cleaning area A in a local range of a level at which the user wants to clean or in a local range of a level to which dirt is attached. The cleaning area A that secures this appropriate cleaning capacity is:
It is desirable to be able to change at the time of use because it changes depending on the user's physical condition, body size, gender, etc.However, even if assuming everyone, it is necessary to minimize the necessary washing from the viewpoint of securing appropriate washing ability There is an area A. This washing area is A0 [m
² ].

[0006] Assuming a certain washing area A in a local area, the higher the washing strength e, that is, the washing water space volume ratio ρ
Is higher, or the flow velocity v is faster, or the washing water space volume ratio ρ is higher and the flow velocity v is faster, or (instantaneous discharge flow rate Q) / (washing area A) is larger, or (instantaneous discharge flow rate Q The larger the (/ cleaning area A) and the higher the flow velocity v, the higher the energy for washing off the dirt, so that the cleaning ability increases. That is, assuming a certain cleaning area A in a local area, the cleaning capacity increases and decreases as the cleaning intensity e increases and decreases.

[0007] Therefore, the cleaning ability depends on the increase / decrease of the cleaning area A and the increase / decrease of the cleaning intensity e in the local range of the level at which the user desires to clean, the local range of the level to which dirt or the like adheres. Increase or decrease.

[0008] Among the basic qualities, a comfortable washing feeling is as follows.
Depending on the user's preference, for example, the local washing water flow rate v
Some users prefer a fast, hard wash feeling, some prefer a soft wash feeling with a slow local cleaning water flow v, and others want to wash with a different wash feeling depending on the user's physical condition and mood. Many.

Therefore, the conventional local cleaning device employs a product specification that allows the instantaneous discharge water amount Q of the local cleaning water discharged from the same local cleaning nozzle to be changed in a wide range, and the instantaneous discharge water amount Q increases and decreases. Generally, the configuration is such that the local washing water flow rate v is increased or decreased, and the instantaneous discharge water volume Q (local washing water flow rate v) desired by the user can be changed with a water pressure knob or a button. By switching the setting with the water pressure knob or button, for example, when the setting is switched to the “strong” side, the instantaneous discharge water amount Q (local cleaning water flow rate v) of the local cleaning water increases, and a hard cleaning feeling can be obtained. When the setting is switched to the "weak" side, the instantaneous discharge amount Q of the local cleaning water (local cleaning water flow rate v) is reduced, and a soft cleaning feeling can be obtained.

On the other hand, in the conventional local cleaning device, the local cleaning water flow rate v is increased or decreased as the instantaneous discharge water amount Q is increased or decreased. As described above, the cleaning ability is changed as the cleaning intensity e is increased or decreased. In order to achieve both a comfortable washing feeling and an appropriate washing capacity, the instantaneous discharge water volume Q, the local washing water flow rate v and the washing water space can be secured even when the water pressure knob and the button are set to the "weak" side. The volume ratio ρ is determined.

[0011]

However, the conventional local cleaning device has a problem in that the instantaneous discharge water amount Q, the local cleaning water flow rate v, and the cleaning water space which can secure appropriate cleaning performance even when the water pressure knob and the button are set to the "weak" side. The fact that the volume ratio ρ is determined means that the instantaneous discharge water amount Q and the local cleaning water flow velocity v increase as the water pressure knob and the button are set to the “strong” side, and the local cleaning is performed with an appropriate cleaning capability or more. You are washing.

Therefore, the instantaneous discharge water amount Q exceeding the appropriate cleaning ability is only used to correspond to the user's favorite cleaning feeling, and the local cleaning of the conventional local cleaning device is not performed by the user. The cleaning is not performed while controlling the cleaning ability to an appropriate predetermined range while corresponding to the taste of the cleaning feeling. In other words, the conventional local cleaning device is not designed based on an appropriate cleaning capability, but is designed based on a user's feeling of cleaning while ensuring the cleaning capability.

Further, conventionally, when a user wants to wash the washing area A0 or more, the body (buttock) is moved or the nozzle is moved back and forth or left and right. In this case, since only the area A to be cleaned is increased without changing the instantaneous discharge water amount Q and the local cleaning water flow velocity v, the cleaning water space volume ratio ρ decreases. Therefore, the cleaning strength e is reduced, and the cleaning ability is reduced. However, as described above, in the past, the instantaneous discharge water amount Q, the local cleaning water flow velocity v, and the cleaning water space volume ratio ρ were determined so that appropriate cleaning performance could be secured even when the water pressure knob and button were set to the “weak” side. Therefore, most users do not feel dissatisfied with the cleaning performance, but if the user wants to clean at an appropriate lower limit of the cleaning capability or an instantaneous discharge flow rate (discharge flow rate) close to the lower limit, the cleaning time will be longer, There was a problem that filth etc. remained in the local area.

[0014] The present invention is directed to a local cleaning apparatus for solving the above-mentioned problems, wherein the cleaning capacity can be controlled independently of the instantaneous discharge water amount, the cleaning water flow rate, the cleaning water space volume ratio, and the cleaning area. An object of the present invention is to provide a local cleaning device capable of performing cleaning while controlling to a predetermined range, and can be performed regardless of anal cleaning and vaginal cleaning.

[0015]

SUMMARY OF THE INVENTION The present invention is directed to a local cleaning apparatus for cleaning a local human body by discharging local cleaning water from a discharge hole provided in a nozzle.

For example, if it is desired to perform water-saving priority cleaning, the local cleaning water flow rate v, the cleaning water space volume ratio ρ, and the cleaning area A may be controlled so that the cleaning capacity is in an appropriate predetermined range according to the degree of water saving. When the cleaning area priority cleaning is desired to be performed, the instantaneous discharge water amount Q, the local cleaning water flow rate v, and the cleaning water space volume ratio ρ are adjusted so that the cleaning area A is wider than usual and the cleaning performance is in an appropriate predetermined range.

Regardless of whether the user prefers a soft washing feeling with a small flow rate v of the local washing water, the washing ability can be controlled within a predetermined range by controlling the instantaneous discharge water amount Q. In particular, as the user prefers a hard wash feeling with a large flow rate v of the local wash water, the instantaneous discharge water amount Q can be reduced in accordance with a predetermined range of the wash performance, so that high water-saving washing can be performed. As the user prefers a hard cleaning feeling with a large flow rate v of the local cleaning water as in the conventional local cleaning apparatus, there is no problem of cleaning with an excessive cleaning capacity.

According to a fourth aspect of the present invention, since the cleaning capacity control means is a cleaning capacity control means for controlling the spatial volume ratio of the local cleaning water, the user can enjoy a hard cleaning feeling with a large flow rate v of the local cleaning water. Regardless of whether you like it or if you prefer a soft wash feeling with a small flow rate v of the local wash water,
, The cleaning ability can be controlled within a predetermined range. In particular, as the user prefers a hard washing feeling with a large flow rate v of the local washing water, the washing density ρ can be reduced, so that highly water-saving washing can be performed. However, there is no such a problem that the washing is performed with an excessive washing ability as the hard washing feeling with the large flow rate v of the local washing water is preferred.

According to a fifth aspect of the present invention, since the cleaning capacity control means is a cleaning capacity control means for controlling a local cleaning area with the local cleaning water, the user prefers a hard cleaning feeling with a large flow rate v of the local cleaning water. Regardless of whether the user prefers a soft cleaning feeling with a small flow velocity v of the local cleaning water, the cleaning capacity can be controlled within a predetermined range by controlling the local cleaning area A. In particular, as the user prefers a hard cleaning feeling with a large flow rate v of the local cleaning water, a wider area A can be cleaned without increasing the instantaneous discharge flow rate Q.
Even when the intended cleaning of the local area cannot be performed from the beginning, it is possible to clean a large area while securing appropriate cleaning performance without increasing the flow rate. As the user prefers a hard cleaning feeling of large, there is no problem of cleaning with an excessive cleaning ability. However, the local cleaning area A to be controlled needs to be equal to or greater than the cleaning area A0 according to the required quality of the cleaning capacity.

With this arrangement, it is possible to perform cleaning with a large cleaning area with an appropriate cleaning capacity.

According to a ninth aspect of the present invention, the cleaning capacity control means is a cleaning capacity control means for controlling the instantaneous discharge amount of the local cleaning water. Regardless of the case where spot-like cleaning with a small area A is preferred, by controlling the instantaneous discharge water amount Q, the cleaning ability can be controlled within a predetermined range, so that a user cannot clean a part intended by himself / herself. In such a case, if the cleaning is initially set to be wide and the local cleaning area A is large, cleaning with a large cleaning area can be performed with an appropriate cleaning capacity.

According to a tenth aspect of the present invention, the cleaning capacity control means is a cleaning capacity control means for controlling a space volume ratio of the local cleaning water, so that the user may prefer wide cleaning with a large local cleaning area A. Regardless of the preference for spot-like washing with a small local washing area A, by controlling the washing water space volume ratio ρ, the washing ability can be controlled within a predetermined range, and the part intended by the user himself can be controlled. If it is not possible to clean the cleaning area, it is possible to perform cleaning with a large cleaning area with an appropriate cleaning capability by first setting wide cleaning with a large local cleaning area A.

In the case where the user can not clean the intended part by himself or herself, if the user can set the wide cleaning with the large local cleaning area A first, the cleaning area can be controlled with an appropriate cleaning capacity. Large cleaning can be performed.

According to a twelfth aspect of the present invention, the cleaning capacity control means is a cleaning capacity control means for controlling the cleaning capacity at a constant level, so that the instantaneous discharge water quantity Q can be ensured according to the user's preference. In addition, it is possible to control the local washing water flow velocity v and the washing water space volume ratio ρ, and it is possible to perform washing with a constant and stable washing ability while sufficiently responding to various users' washing preferences.

The cleaning capacity control means may be a cleaning capacity setting section for setting the cleaning capacity, and the cleaning capacity control means for controlling the cleaning capacity to a set value set by the cleaning capacity setting section. So, according to the user's preference,
Instantaneous discharge water volume Q, local cleaning water flow rate v, and cleaning water space volume ratio ρ can be controlled so that the cleaning capacity is set to the set value. Stable cleaning performance while sufficiently responding to various users' cleaning preferences Can be washed.

FIG. 1 is a schematic diagram showing an embodiment of the present invention. First, the path of the washing water will be described. When the washing water is supplied from the washing water supply means 1, the washing water flows into the washing nozzle 3 through the heat exchanger 2 which makes the washing water warm, and the discharge hole 31 is formed.
And discharges the liquid to perform local cleaning. The cleaning water supply means 1 includes a flow control valve 12 and a water stop valve 11,
When the tap water pressure for discharging is insufficient or when tap water pressure is not used, it is necessary to attach the water pump 13.

As the discharge form in which the instantaneous discharge flow rate Q, the local cleaning water flow velocity v, the cleaning water space volume ratio ρ, and the cleaning area A can be controlled by the cleaning capacity control means 7, the discharge shown in FIG. 7, intermittent discharge in which the cleaning water is discharged intermittently in time, rotary discharge in which the cleaning water after discharging shown in FIG. 5 rotates, oscillating discharge in which the cleaning water after discharging shown in FIG. 6 swings, and FIG. Shower discharge in which washing water is discharged from a discharge hole having a plurality of discharge holes as shown in FIG. 1 and further combining these discharge forms are conceivable, but the instantaneous discharge flow rate Q and the local cleaning water flow rate v are not limited to the above discharge forms. And flush water space volume ratio ρ
The discharge is not limited to this as long as the discharge can control the cleaning area A.

Next, a specific control method in the cleaning ability control means 7 will be described for each discharge mode. FIG. 8 shows a configuration diagram in the case where air is mixed in the cleaning water. The control of the instantaneous discharge flow rate Q, the local cleaning water flow rate v, and the cleaning water space volume ratio ρ when air is mixed into the cleaning water is performed by controlling the water pump 13 or the flow rate control valve 12 and the air pump 41. The water pump 13 and the flow control valve 12 are controlled by the cleaning water supply control means 71. The aeration unit 41a
The space downstream of the heat exchanger 2 to the discharge hole of the washing nozzle is best, and it is not necessary to increase the capacity of the air pump 41 as downstream. The air pump 41 is controlled by the air pump control means 72. Since the air mixing rate is determined by the balance between the water pressure and the air pressure of the mixing section, the air mixing rate can be controlled by controlling the capacity of the water pump 13 or the flow rate control valve 12 and the air pump 41, and the space after the washing water is discharged. By controlling the volume ratio ρ and changing the air mixing rate independently of the instantaneous discharge water amount Q, the local cleaning water flow velocity v can be controlled independently of the instantaneous discharge water amount Q.

FIG. 9 shows a configuration diagram in the case of intermittent discharge in which the cleaning water is discharged intermittently over time. The control of the instantaneous discharge flow rate Q, the local cleaning water flow rate v, and the cleaning water space volume ratio ρ in the case of intermittent discharge in which the cleaning water is discharged intermittently is performed by the water pump 1.
3 or the flow control valve 12 and the intermittent variable valve 43 for controlling the flush water discharge time in a temporal intermittent cycle or one intermittent cycle. The water pump 13 and the flow control valve 12 are controlled by the cleaning water supply control means 71. The intermittent variable valve 43 may be, for example, a rotary on-off valve (disc valve) as shown in FIG.
It may be a plunger-type on-off valve. Further, the water pump 13 may be a positive displacement water pump, and the flushing cycle or the stroke of the water pump may be used to control the temporal intermittent cycle or the flush water discharge time in one intermittent cycle. The intermittent responsiveness improves as the position of the on-off valve is provided on the downstream side.
The intermittent variable valve 43 is controlled by intermittent valve variable control means 73.

FIG. 11 shows a configuration diagram in the case of rotary discharge in which the cleaning water after discharge is rotated. The control of the instantaneous discharge flow rate Q, the local cleaning water flow rate v, the cleaning water space volume ratio ρ, and the cleaning area A in the case of the rotary discharge in which the cleaning water after the discharge rotates is performed by the water pump 13.
Alternatively, the control is performed by controlling the flow control valve 12 and the washing water rotating means 42. Water pump 13 and flow control valve 1
2 is controlled by the cleaning water supply control means 71. As shown in FIG. 11, the cleaning water rotating means 42 may rotate the cleaning water by rotating a discharge motor by attaching a rotation motor to the tip of the cleaning nozzle, or may rotate the nozzle itself. In the case of rotating the nozzle itself, FIG.
As shown in FIG. 12, the washing water may be rotated by a combination of the front, rear, left and right movements of the nozzle, and as shown in FIG.
The nozzle may be directly rotated by one motor. The cleaning water rotation means 42 is controlled by the cleaning water rotation control means 74. For example, by controlling the rotation speed of the rotary discharge, when the rotation speed is high, the effect of the centrifugal force is large, the washing area A can be increased, and the space volume ratio ρ can be reduced,
When the rotation speed is low, the effect of the centrifugal force is small, and the washing area A can be reduced and the space volume ratio ρ can be increased. Further, by controlling the rotation diameter of the rotary discharge, when the rotation diameter is large, the cleaning area A can be increased and the space volume ratio ρ can be reduced, and when the rotation diameter is small, the cleaning area A can be reduced. The space volume ratio ρ can be increased.

FIG. 13 shows a configuration diagram in the case of oscillating discharge in which the cleaning water after oscillating is oscillated. The control of the instantaneous discharge flow rate Q, the local cleaning water flow rate v, the cleaning water space volume ratio ρ, and the cleaning area A in the case of the oscillating discharge in which the cleaning water oscillates is performed by the water pump 13.
Alternatively, the control is performed by controlling the flow rate control valve 12 and the washing water oscillating means 44. Water pump 13 and flow control valve 1
2 is controlled by the cleaning water supply control means 71. The washing water oscillating means 44 may swing the washing water by attaching a vibration motor to the tip of the washing nozzle and oscillating the ejection hole, or by attaching a fluid element to the ejection hole to swing the washing water. Is also good. The washing water swinging means 44 is provided with the washing water swinging control means 7.
5 is controlled. For example, by controlling the oscillating frequency of the oscillating discharge, when the oscillating frequency is high, the effect of acceleration in the oscillating direction is large, the washing area A can be increased, and the space volume ratio ρ can be reduced, When the oscillating frequency is low, the effect of acceleration in the oscillating direction is small, and the cleaning area A can be reduced and the space volume ratio ρ can be increased. Further, by controlling the swing diameter of the swing discharge, when the swing diameter is large, the cleaning area A can be increased and the space volume ratio ρ can be reduced, and when the swing diameter is small, the cleaning area A can be reduced. The area A can be reduced and the space volume ratio ρ can be increased.

FIG. 14 shows a configuration diagram in the case of shower discharge in which cleaning water is discharged from a discharge hole having a plurality of discharge holes. The control of the instantaneous discharge flow rate Q, the local cleaning water flow rate v, the cleaning water space volume ratio ρ, and the cleaning area A in the case of shower discharge in which the cleaning water is discharged from the discharge holes having a plurality of discharge holes is performed by using the water pump 13 or the flow rate. This is performed by controlling the control valve 12 and the discharge hole variable valve 45. The water pump 13 and the flow control valve 12 are controlled by the cleaning water supply control means 71. As shown in FIG. 15, for example, the discharge hole variable valve 45 may be a rotary discharge hole variable valve (disc valve), or each discharge hole may be controlled by an open / close valve. This makes it possible to control the number of ejection holes. By controlling the number of discharge holes, it is possible to easily control the cleaning water space volume ratio ρ and the cleaning area A.

Further, by combining the above-described discharge modes, for example, if the cleaning water containing air is discharged from a discharge hole having a plurality of discharge holes, the instantaneous discharge water amount Q, the local cleaning water flow rate v, the cleaning water Not only the control pattern of the space volume ratio ρ increases, but also the cleaning area A that cannot be controlled only by mixing air can be controlled. In addition, by combining the rotation discharge in which the cleaning water after discharge rotates and the discharge mixed with air,
Similarly, not only the control pattern of the instantaneous discharge water amount Q, the local cleaning water flow velocity v, and the cleaning water space volume ratio ρ increases, but also the cleaning area A that cannot be controlled only by mixing air can be controlled.

Next, the operation of the above embodiment of the present invention will be described. The discharge form may be any of the above discharge forms or a combination of the above discharge forms. By performing the above control, the instantaneous discharge flow rate Q, the local cleaning water flow rate v, the cleaning water space volume ratio Since ρ and the cleaning area A can be controlled, a description will be given below of a discharge mode in which discharge in which air is mixed and rotary discharge in which cleaning water after discharge rotates are combined, as shown in the schematic configuration diagram of FIG. FIG. 16 is an example of an operation panel operated by a user to perform desired cleaning. The user can set the cleaning intensity e to a predetermined range by first setting the cleaning capacity switch 81 to a desired position. Here, the predetermined range of the cleaning intensity e with respect to the set position of the cleaning capacity switch 81 may be constant or may be controlled so as to be within a certain width. A predetermined range of the cleaning intensity e may be determined at the design stage so that the quality can be ensured without selection by the user.

Next, when the user wants to prioritize the cleaning area, for example, according to the preference of the cleaning, the user presses the priority button 84a and sets the desired cleaning area with the cleaning area switch 84. By controlling the number of rotations of the discharge hole 31 according to the setting of the cleaning area switch 84, a desired cleaning area can be cleaned. After that, by changing the setting of the washing feeling switch 83 so that the washing can be performed with a desired washing feeling, the water pump 13 or the flow rate control valve 12 and the air pump 41 are controlled in accordance with the setting of the washing feeling switch 83. The washing water flow rate v can be controlled, and washing can be performed with a desired washing feeling. Further, even though the washing is performed with a desired washing feeling, by controlling the water pump 13 or the flow control valve 12 and the air pump 41 in accordance with the washing water flow velocity v, the washing intensity e is within a predetermined range. , The instantaneous discharge water amount Q and the space volume ratio ρ can be controlled, and the cleaning ability can be controlled within a predetermined range set by the user. Therefore, unlike a conventional local cleaning device, there is no such a problem that a user prefers a hard cleaning feeling with a large flow rate v of the local cleaning water and performs cleaning with an excessive cleaning ability.

Similarly, when priority is given to water saving, the priority button 82a is pressed, and the instantaneous discharge water amount Q is set by the water saving switch 82 in accordance with the level of water saving. Thereafter, for example, the cleaning area is changed from wide to spot in order to perform cleaning in a wide area at first and gradually perform spot-like cleaning. The number of rotations is controlled to change the washing area A, and washing can be performed with a desired washing area. further,
Despite washing with a desired washing area, depending on the washing area A, the water pump 13 or the flow control valve 12
By controlling the air pump 41, the washing water flow rate v and the space volume ratio ρ can be controlled such that the washing intensity e falls within a predetermined range while the instantaneous discharge water amount Q is within a predetermined range. The cleaning ability can be controlled within a predetermined range set by the user. Further, when priority is given to water saving, for example, a washing feeling switch is used to wash the washing feeling first with a soft washing feeling with a slow washing flow rate v and gradually with a hard washing feeling with a fast washing flow rate v. By changing the 83 from software to hardware, the washing water flow rate v can be controlled by controlling the water pump 13 or the flow rate control valve 12 and the air pump 41 in accordance with the setting of the washing feeling switch 83, and the desired washing can be performed. It can be washed with a feeling. Further, the instantaneous discharge water amount Q is controlled to a predetermined value by controlling the rotation speed of the water pump 13 or the flow control valve 12, the air pump 41, and the discharge hole 31 even though the cleaning is performed with a desired cleaning feeling. While being within the range, the space volume ratio ρ and the cleaning area A can be controlled so that the cleaning intensity e falls within a predetermined range, and the cleaning ability can be controlled within a predetermined range set by the user. Further, if the instantaneous discharge water amount Q is determined to be constant at the design stage at a level where quality can be ensured without being selected by a user, the temperature control mechanism by the heat exchanger 2 can be simplified, and It is easy to keep the temperature of the washing water constant, and not only can the quality be improved, but also the heat exchanger 2 and the heat exchanger control means 9 can be incorporated at low cost.

Similarly, when priority is given to the washing feeling, the priority button 83a is pressed, and the washing water flow rate v of the desired washing feeling is set by the washing feeling switch 83. Thereafter, for example, the cleaning area is changed from wide to spot in order to perform cleaning in a wide area at first and gradually perform spot-like cleaning. The number of rotations is controlled to change the washing area A, and washing can be performed with a desired washing area. Further, although the washing is performed with a desired washing area, the washing water flow rate v is controlled within a predetermined range by controlling the water pump 13 or the flow control valve 12 and the air pump 41 in accordance with the washing area A. However, it is possible to control the instantaneous discharge water amount Q and the space volume ratio ρ such that the cleaning intensity e falls within a predetermined range,
The cleaning ability can be controlled within a predetermined range set by the user.

In the above embodiment, the case where the cleaning capacity is controlled within a predetermined range by giving priority to the space volume ratio or the case where the cleaning capability is controlled within a predetermined range while changing the space volume ratio according to the user's preference. Although omitted, a space volume ratio variable switch may be provided in order to correspond to various washing preferences of the user.

As described above, the washing parameters (water saving, washing feeling, washing area, space volume ratio) to be prioritized and the washing parameters (water saving, washing feeling,
By determining the cleaning area and the space volume ratio), other cleaning parameters can be controlled in accordance with the discharge form so that the cleaning ability can be controlled within a predetermined range according to the conditions. It is possible to clean a local area with an appropriate cleaning ability while sufficiently supporting a desired cleaning.

In this embodiment, the cleaning capacity has been described assuming a case where the cleaning capacity is averaged over the entire cleaning area and the time is steady. However, the instantaneous discharge water amount Q and the cleaning water flow rate v within the cleaning area to be cleaned are described. By adding a spatial and temporal distribution to the volume ratio and the space volume ratio ρ, a spatial and temporal distribution can also be added to the cleaning capacity within the cleaning area, and various local cleaning controls can be performed.

Furthermore, in the present embodiment, the description has been given in which the user changes the setting at each use according to his / her preference. However, a cleaning mode storage unit is provided, and once the cleaning mode is set, the cleaning mode is set. It may be possible to perform washing in a preferred washing mode by pressing a switch of the storage unit, or an individual recognition unit may be provided so that each individual's favorite washing is automatically performed according to the determined individual. . Even when performing these cleanings, the instantaneous discharge flow rate Q, the local cleaning water flow velocity v, the cleaning water space volume ratio ρ, and the cleaning area A are adjusted according to the discharge mode so that the cleaning capacity can be controlled within a predetermined range.
