Description

[Detailed description of the invention] (Industrial application field) It is absolutely necessary for a toilet user to clean the anal area after defecating in order to keep the body in a comfortable condition. It is. however,
Merely wiping with toilet paper does not sufficiently clean the dirt, which not only poses a hygienic problem, but also leaves a person feeling uncomfortable after using the toilet.

Particularly for people suffering from hemorrhoids, the use of toilet paper and the like is painful and causes further aggravation of the symptoms. Also, pregnant women, elderly people,
For patients with obesity, hypertension, etc., as well as other injured and sick people, they are forced to take an awkward posture when using toilet paper, which may have an adverse effect on their health. Furthermore, it is very difficult for people with upper extremity disabilities to use toilet paver. Therefore, there is an urgent need for a toilet bowl to be equipped with a mechanism for squirting hot water to cleanse the anal region after defecating.

The present invention relates to a toilet bowl with a cleaning mechanism that satisfies the above requirements and is effective for making daily life more comfortable.

(Prior Art) As shown in FIG. 3, there is a conventional toilet with a cleaning mechanism in which the toilet main body B, the low tank 12, and the cleaning mechanism are integrally constructed. this is,
Cleaning of the hot water tank, hot water heater, thermostat for adjusting water temperature, pressurizing pump for cleaning water, means for controlling cleaning water pressure, hot air dryer, means for adjusting hot air temperature (not shown), cleaning nozzle 15, etc. The mechanism is
It is built into the toilet body B. Fourth
The figure shows a partially cutaway side view of the toilet bowl with an integrated cleaning mechanism, and the insertion hole 16 for the cleaning nozzle 15 is located slightly below the rear wall surface 11a of the toilet bowl 11 and is located above the insertion hole 16. is provided with an outlet 17 for hot air supplied from the hot air dryer. The cleaning nozzle 15 has an expandable and retractable cylindrical structure, and has an appropriate number of cleaning water ejection holes 15a formed at its tip. When performing the cleaning function, the cleaning nozzle 15 is extended to approximately right below the area desired to be cleaned, and when the blow-off hole 15a is positioned approximately directly below the desired area, cleaning water is jetted out to perform cleaning.

On the other hand, a cleaning mechanism that is integrated with the toilet lid, toilet seat, etc. is attached to the toilet bowl. Attached flush mechanism toilets have also been used in the past. As shown in FIGS. 5 to 8, there is a device of this kind in which a cleaning mechanism is housed in a storage case.

In FIG. 5, the cleaning mechanism 23 includes a toilet seat 28 and a toilet lid 29.
The cleaning mechanism 23 shown in FIG.
Figures A and B. A cleaning mechanism 23 is provided behind the toilet seat 28 and the toilet lid 29. A cleaning mechanism 23 is provided at the bottom of the toilet seat 28, and a retractable cleaning nozzle 25 is installed at the bottom of the toilet seat 28. An outlet 27 is provided, and the cleaning nozzle 25 is inserted through the gap between the top surface of the toilet bowl and the bottom surface of the toilet seat, and warm air is supplied.

Further, FIG. 7 shows a cleaning mechanism 33 provided on the sides of a toilet seat 38 and a toilet lid 39. and,
8A and 8B are a front view and a side sectional view of the cleaning mechanism 33 shown in FIG. 7. The cleaning nozzle 35 is
The base shaft part passes from the side of the toilet bowl between the bottom surface of the toilet seat 38 and the top surface of the toilet bowl, and the intermediate part and the tip part are arm-shaped and extend to the center of the toilet bowl while curving along the inner wall surface of the toilet bowl. There is. A washing water spouting part 35b is provided at the tip of the arm 35a, and the arm base is connected to the operating lever 6 of the washing mechanism on the side of the toilet bowl.
Concatenated with 0. By rotating the operating lever 60, the arm 35a can be swung and the spraying angle of the cleaning water can be changed. Further, the warm air outlet 37 is provided at the bottom of the toilet seat 38, similar to the attached cleaning mechanism shown in FIG. 5 above.

(Problems to be solved by the invention) Desired items for toilets with a flushing mechanism are listed below: (1) A sufficient amount of flushing water is available.

(2) Since sensitive areas are to be cleaned, the force of the cleaning water should be within a range that provides sufficient cleaning ability, and should not be excessive.

(3) Cleaning water should be ejected from almost directly below in order to have good cleaning efficiency and not to scatter the cleaning water below the desired area to be cleaned.

(4) During cleaning, the temperature of the cleaning water does not change and is maintained at an appropriate temperature.

(5) The supply amount of hot air for drying is large.

(6) The hot air outlet should be located directly below the desired area as much as possible.

(7) Since the installation area of a washroom in a general household is often limited, there should be no wasted installation space.

(8) Easy to manufacture, install, and maintain.

and so on. From these viewpoints, each of the conventional toilet bowls with a cleaning mechanism described above will be examined.

The integrated type toilet bowl with a cleaning mechanism shown in FIGS. 3 and 4 uses a large-sized cleaning mechanism, so that both the amount of flushing water and the amount of warm air supplied are abundant. The cleaning nozzle 15 is designed to spray cleaning water from almost directly below, and the hot air outlet 17
Since it is located near the bottom, both cleaning efficiency and drying efficiency are good. Since the cleaning mechanism is housed inside the toilet bowl body B, the external appearance is also excellent. However, the above-mentioned integrated type toilet bowl with a flushing mechanism has a complicated structure, requires a complicated manufacturing process, and is expensive. Also, since it is an integrated type with a built-in cleaning mechanism, it weighs about 100 kg. Therefore, it is difficult to load, unload, transfer, and transport during the distribution process, and installation and other workability during construction is poor. Furthermore, even when attempting to repair, replace parts, or make improvements due to aging, the main part of the cleaning mechanism is installed deep inside the toilet body, making the work difficult and poor in maintainability. That will happen.

The attached cleaning mechanism shown in FIGS. 5 to 8 is
While it has excellent versatility in that it can be installed on many types of toilet bowls, it also includes all cleaning nozzles, hot water storage tanks, hot water heaters, pressure pumps, hot air dryers, and control mechanisms for water temperature, water pressure, and hot air temperature. The cleaning mechanism becomes very bulky because it needs to be housed in a storage case. Therefore, there are restrictions on where it can be installed, and when it is installed on a toilet bowl, it gives a feeling of spatial pressure and at the same time
The external shape also becomes inferior. Functionally, compared to the above-mentioned toilet with an integrated flushing mechanism, the hot water storage tank, pressurizing pump, hot air dryer, etc. cannot be made so large, so the amount of flushing water ejected,
Ejection pressure and hot air supply amount are limited. Moreover, in the cleaning mechanism shown in FIGS. 5 and 6, the cleaning nozzle 25 and the warm air outlet 27 are both provided above the toilet bowl, so the cleaning water and warm air are directed to the desired area. It is supplied only at a very shallow angle.
That is, there is a drawback that it is difficult to obtain the optimum jetting angle of the washing water and the blowing direction of the hot air.

Furthermore, it can be said that the attached type cleaning mechanism shown in FIGS. 7 and 8 has been improved to a certain extent in terms of the spraying angle of cleaning water, compared to the above-mentioned cleaning mechanism. However, the amount of jetting water and the amount of hot air supplied cannot be said to be sufficient due to the limitations of the installation type. The blowing direction of hot air is also a position of low efficiency. Moreover, the problem that there are many protruding parts when attached to a toilet bowl remains unresolved.

(Means for Solving the Problems) The present invention is a toilet bowl with a cleaning mechanism devised in view of the above problems, and its features are as follows:
Consisting of a toilet main body provided with a recessed part with an opening on the upper surface at the rear of the toilet bowl, and a cleaning mechanism equipped with a hanging part containing cleaning equipment that is removably housed in the recessed part. It is.

In addition, in the toilet bowl with a cleaning mechanism according to the above configuration, in order to improve the cleaning efficiency, a cleaning nozzle is provided in the hanging part of the cleaning mechanism that can move forward and backward on the entire surface when stored in the recessed fitting part, and on the other hand, the toilet bowl An insertion hole may be provided in the main body at a position corresponding to the cleaning nozzle of the hanging portion, which penetrates from the recessed fitting portion toward the rear wall surface of the toilet bowl.

Furthermore, in order to increase the efficiency of hot air drying after washing,
In the hanging part of the washing mechanism, a warm air supply window is provided at the upper part of the front part when the cleaning mechanism is stored in the recessed part, and the warm air is supplied from a warm air dryer built in the hanging part, and the toilet main body has the above-mentioned window. A hot air outlet may be provided at a position corresponding to the hot air supply window, penetrating from the recessed fitting portion toward the rear wall surface of the toilet bowl.

(Function of the device) By adopting the above configuration, the toilet bowl with a cleaning mechanism according to the present invention has the hanging portion of the cleaning mechanism stored in the recessed part of the toilet body, so that it protrudes from the toilet bowl when the two are combined. There will be only a small portion. Therefore, the toilet bowl has an excellent appearance comparable to that of a toilet bowl with an integrated cleaning mechanism. Moreover, since the cleaning mechanism is removable from the toilet body, it is easier to manufacture, install, and maintain than an integrated type.
That is, the toilet with a cleaning mechanism according to the present invention has both the advantages of an integrated type of cleaning mechanism and the advantages of an attached type.

In addition, by providing an insertion hole in the toilet bowl body that extends from the recessed fitting part toward the rear wall surface of the toilet bowl, and inserting the cleaning nozzle of the cleaning mechanism therethrough, the cleaning water is ejected from almost directly below the area that needs cleaning. becomes possible.

Furthermore, by providing the toilet bowl body with a warm air outlet that penetrates from the recessed fitting portion toward the rear wall surface of the toilet bowl, it is possible to improve the hot air drying efficiency after hot water washing.

(Embodiment) FIG. 1 is a perspective view of an embodiment of the toilet bowl with a cleaning mechanism according to the present invention, and FIG. 2 is a partially cutaway side view thereof. A recessed fitting part 4 is provided between the toilet bowl 1 of the toilet main body A and the low tank 2, and a hanging part 3a of a cleaning mechanism 3, which will be described later, is accommodated in the recessed fitting part 4 as shown by the arrow drawn with a dashed-dotted line. . An insertion hole 6 through which the cleaning nozzle 5 of the cleaning mechanism 3 enters and exits is provided slightly below the rear wall surface 1a of the toilet bowl 1, and above the insertion hole 6 (in this embodiment, the upper edge of the toilet bowl 1 There is a hot air outlet 7 supplied from a hot air dryer built in the hanging part 3a of the cleaning mechanism 3 in the rim part 1b (part of the rim part 1b).
is provided.

In addition, by not making the volume of the part of the cleaning mechanism 3 that is not accommodated in the recessed fitting part 4 too large and matching the height of the low tank 2 attached to the toilet main body A, a simple form of cleaning with few protruding parts can be achieved. A toilet with a mechanism can be obtained. Of course, if desired, the low tank 2 can be mounted above the toilet main body A, or a large low tank can be used. Even in such a case, the toilet bowl with a cleaning mechanism according to the present invention can be organized in a neat and functional manner as a whole.

The cleaning mechanism 3 includes a hanging part 3a that is housed in the recessed fitting part 4, and is configured integrally with the toilet seat 8 and the toilet lid 9. Therefore, simply by attaching the cleaning mechanism 3 to the toilet main body A, the toilet seat 8 and toilet lid 9 can be attached to appropriate positions.

In this embodiment, the cleaning mechanism 3 includes a toilet seat 8 and a toilet lid 9.
Although the cleaning mechanism 3 is attached as an integral structure, it is of course also possible to have a structure in which only the cleaning mechanism 3 is attached to the toilet main body A independently. Conventional attached-type cleaning mechanisms need to ensure stability when attached to the toilet bowl, and to ensure a gap between the top surface of the toilet bowl and the bottom surface of the toilet seat that allows for the insertion of a cleaning nozzle and the gap for hot air supply. Due to these two requirements, it was necessary to construct the toilet cover and the toilet seat integrally. However, with the cleaning mechanism of this embodiment, the hanging part 3a is housed in the recessed part 4 provided at the rear of the toilet bowl 1, so no positional shift occurs, and therefore only the cleaning mechanism can be used. Stability is completely ensured even when worn alone, and
An insertion hole 6 for a cleaning nozzle 5 is provided on the rear wall surface 1a of the toilet bowl part.
Since the toilet has a structure in which a hot air outlet 7 is provided, there is no need to provide a space between the toilet main body A and the toilet seat 8.

A cleaning device is configured in the hanging portion 3a.
A hot water storage tank, a hot water heater, a thermostat for adjusting water temperature, a pressurizing pump for washing water, a means for controlling washing water pressure, a hot air dryer, a means for adjusting hot air temperature, etc. are installed inside (not shown), and the hanging part A cleaning nozzle 5 and a hot air supply window 10 are provided on the front surface of 3a.

The cleaning nozzle 5 has an appropriate number of ejection holes 5 at its tip.
It is an expandable cylinder type with a perforation.
The expansion and contraction operation is due to the combination of the cleaning water pressure raised by the pressure pump and the built-in spring. When the cleaning mechanism 3 is not in use, the cleaning nozzle 5 is housed inside the hanging portion 3a in a shortened state biased by an internal spring. When performing the cleaning function, the cleaning nozzle 5 is moved to the hanging part 3a by the water pressure of the cleaning water sent from the pressure pump.
It is pushed out from inside and extends to approximately right below the desired area to be cleaned, and the cleaning water is squirted from the spout hole 5a. After cleaning the desired area, stop the supply of cleaning water.
The cleaning nozzle 5 returns to the shortened state by the force of the built-in spring.

Since the cleaning nozzle 5 has the above-described mechanism, it does not pose any problem when the hanging portion 3a of the cleaning mechanism 3 is accommodated in the recessed fitting portion 4 at the rear of the toilet bowl.

By providing the washing mechanism 3 with the hanging part 3a,
Without making the cleaning mechanism 3 protrude from the toilet main body A, a larger hot water tank, pressure pump,
Since a hot air dryer can be used, both cleaning and drying performance can be improved.

In toilets with a cleaning mechanism, the cleaning sensation is narrow,
Moreover, it is desirable that the cleaning capacity is sufficient. For this purpose, it is necessary to jet the cleaning water with an appropriate force from as many jet holes as possible. However, as the number of ejection holes increases, it is impossible to obtain a predetermined cleaning water force without increasing the amount of cleaning water supplied. In this embodiment, as mentioned above, a larger pressurizing pump than before can be used, so in order to supply a large amount of cleaning water with sufficient water pressure as necessary,
The cleaning mechanism provides a pleasant cleaning sensation.

Furthermore, since the capacity of the hot water storage tank is increased, a large amount of washing water at a constant temperature is prepared. Therefore, the water temperature does not change during washing, so there is no risk of boiling water spewing out causing burns or cold water spouting causing unpleasant irritation.

Regarding the drying function, the capacity of the hot air dryer can be increased, and the hot air outlet 7, which has a wider opening than conventional attached cleaning mechanisms, is located directly below the user, so drying efficiency is extremely high. good for

Although the toilet bowl with a cleaning mechanism has been described above, in which the insertion hole 6 for the cleaning nozzle 5 and the hot air outlet 7 are provided on the rear wall surface of the toilet bowl portion, the present invention is not necessarily limited to this. For example, a hanging part is provided in an attached cleaning mechanism in which the cleaning nozzle and warm air outlet are located between the lower surface of the toilet seat and the upper surface of the toilet bowl body, as in conventional cases, and the hanging part is housed in the recessed part of the toilet bowl. It is also possible to have a structure in which it is forced. By doing so, although the external shape is approximately the same as the conventional one, a larger hot water storage tank and hot air dryer can be used. Therefore, it is possible to provide an attached cleaning mechanism that can overcome the supply amount of cleaning water and hot air.

(Effects of the invention) As described above, the toilet bowl with a cleaning mechanism according to the present invention has a cleaning nozzle, a hot water storage tank, a hot water heater, a pressure pump, a hot air dryer, a water temperature, and a water pressure, which constitute the cleaning equipment. and hot air temperature control means, etc., are housed in the hanging part of the cleaning mechanism, and the hanging part is housed in a recessed part provided at the rear of the toilet bowl, so that it protrudes from the toilet bowl even when the cleaning mechanism is installed. Most of the parts are gone. Therefore, it can be installed even in a narrow washroom where it would be difficult to install a conventional attached type cleaning mechanism.

Since there are almost no parts protruding from the toilet bowl, the external shape is simple. This not only has the effect of being visually beautiful, but also has an effect on taste. If there are many protruding parts, it is easy to cause damage to the equipment due to carelessness or injury due to negligence. Therefore, simplifying the external shape prevents unexpected accidents. In addition, since cleaning and maintenance are easy, hygiene management is thorough and comfortable use is possible.

If the toilet body is provided with an insertion hole that penetrates from the recessed part toward the rear wall surface behind the toilet bowl, the cleaning nozzle can be inserted from slightly below the toilet bowl, making it ideal for almost perpendicular to the desired location. Cleaning water can be spouted at a suitable angle. Therefore, cleaning efficiency is high, and hot water is not splashed on areas other than the cleaning area. Although it has been difficult to achieve this with conventional attached-type cleaning mechanisms, the toilet bowl with a cleaning mechanism according to the present invention can achieve the same effects as an integrated toilet bowl with a cleaning mechanism.

The hot air outlet supplied from the hot air dryer,
When installed on the rear wall of the toilet bowl, a hot air blowing direction with high drying efficiency can be obtained. Furthermore, since an opening with a sufficient margin can be provided, the amount of hot air supplied can be increased. Therefore, the drying capacity is greatly improved.

Although it is an attached type, the structure allows the hanging part of the cleaning mechanism to be housed in the recessed part at the rear of the toilet bowl.
Larger hot water storage tanks and pressure pumps can be used. In addition, since an abundant amount of washing water is supplied, the washing capacity is increased. In addition, the increase in hot water storage eliminates changes in water temperature during cleaning, making it more comfortable to use, and the larger pressurizing pump allows cleaning water to be spewed out with appropriate water force from multiple spout holes, making it an excellent choice. You can get a good cleaning feeling.

Furthermore, the same can be said about hot air dryers. That is, since a larger hot air dryer can be used, the drying capacity is improved.

The cleaning mechanism is removably attached to the toilet bowl, making it easy to manufacture and easy to load, unload, transport, and
The construction and workability of transportation, installation, etc. is also good.
Maintenance and inspection such as parts replacement and repair are also easy.
For example, when replacing parts, the cleaning mechanism can be easily removed from the toilet bowl body, making it easy to reach the desired replacement location with hands or instruments. Furthermore, since the cleaning mechanism itself can be replaced, the cleaning mechanism can be improved by replacing it with a conventionally improved cleaning mechanism.

Demonstrates excellent effects such as

In short, although the present invention is an attached type, it has the advantages of an integrated type, that is, excellent cleaning ability and drying ability, and a simple external shape. The present invention provides a toilet with a flushing mechanism that takes advantage of the advantages of easy construction, maintenance, and inspection.
