DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sanitary cleaning device for cleaning the anus and other private parts with cleansing water.

Structure of a conventional example and its problems The structure of a conventional sanitary cleaning device is shown in FIG. This example shows a cleaning toilet bowl that has the function of cleaning the anus after defecating. In the figure, 1 is a toilet bowl, 2
3 is a toilet seat, 3 is a toilet seat lid, 4 is a cistern for storing water for flushing in the toilet bowl 1, 5 is a user sitting on the toilet seat 2, and 6 is a system for discharging cleaning water into the anus of the user 5. a cleaning nozzle; 7 is a water filter submerged in water in the cistern 4; 8 is a hose; 9 is a water filter that connects the water filter to the cistern 4;
A pump 10 is a storage box that houses the pump 9, the hose 8, and the like.

In the above-mentioned sanitary cleaning device, the user 5 discharges cleansing water into his anus to cleanse himself after using the toilet.

Conventional methods for discharging washing water include a method of discharging water at a constant water pressure, or a method in which the rotation speed of the motor that energizes the pump 9 can be varied by external operation to adjust the water pressure and amount of washing water to the preference of the user 5. This was done in one of two ways. However, in order to clean the anus completely and in a short time after defecating, a water pressure of at least a certain amount is required, and it is preferable to use more water than that, but some people experience pain in the anus. The pain is unbearable, especially in the case of people with hemorrhoids. In that case, reducing the water pressure will alleviate the pain, but cleaning will be incomplete, which is inconvenient. Furthermore, even if the user does not feel any pain, washing with a constant water pressure gives the user a monotonous feeling and lacks comfort.

Purpose of the Invention The present invention has been made in consideration of such conventional problems, and an object of the present invention is to provide a sanitary cleaning device that maintains a high cleaning effect, does not cause strong irritation to private parts such as the anus, and can provide a comfortable feeling of use. This is the purpose.

Structure of the Invention In order to achieve the above object, there is provided a washing water supply means for discharging washing water for washing private parts of the human body, a setting means for setting the amount of water of the washing water supply means, and a signal generation means for causing fluctuation in output. , a control means for discharging water at an amount according to the setting means, a wash water supply control means for fluctuating the amount of water in the wash water supply means in accordance with the output of the signal generating means, and a switch for giving the fluctuation; The control means is configured to fluctuate the water amount of the wash water supply means in response to fluctuations in the output of the signal generation means within a certain range above and below the set water amount value of the wash water supply setting means.

DESCRIPTION OF EMBODIMENTS The structure of a sanitary cleaning device according to an embodiment of the present invention will be described below with reference to FIGS. 2 and 3. The configuration of the conventional sanitary cleaning device shown in FIG. 1 is directly applied to the present invention, and the same members are given the same numbers. FIG. 2 shows the washing water discharge operation section of the sanitary washing device of the present invention. In the figure, 11 is a water amount setting means (or washing water amount setting volume) of washing water, and 12 is a switch that gives fluctuation to the washing water. (Hereafter referred to as fluctuation switch). 13 is
This is an indicator that lights up when the fluctuation switch is turned on.

FIG. 3 is a schematic diagram of an embodiment of the sanitary cleaning device of the present invention. 11 is a washing water amount setting means shown in FIG. 2; 12 is a fluctuation switch;
Reference numeral 14 denotes a cleaning water supply means, which in this example is a motor that energizes the pump 9. 15 is a signal generating means for generating a fluctuation signal whose power spectrum is inversely proportional to the frequency, and 16 is a control means for controlling the amount of water according to the washing water amount setting means 11. In this example, a microcomputer is used, and the fluctuation switch 12 is ON. The signal generating means 1
The cleaning water supply control means receives the signal No. 5 and controls the rotation speed of the motor 9. 17 is an AC zero voltage pulse generator, 18 is an AD conversion circuit for converting an analog value of the washing water amount setting means into a digital value, and 19 is a motor drive circuit.

In the above configuration, first, a method for controlling the rotation speed of the motor will be described. In this example,
The motor rotation speed is controlled by phase control. Note that as the rotational speed of the motor increases, the amount of washing water increases, and therefore the washing water pressure applied to the private parts also naturally increases.

Phase control refers to alternating current voltage 2 as shown in Figure 4.
This refers to a method in which power is adjusted (in one embodiment of the present invention, motor rotation speed is controlled) by controlling the conduction angle θn21 for each cycle.

Therefore, in one embodiment of the present invention, when the waveform of the AC voltage 20 passes through zero voltage (zero cross), the AC zero voltage pulse 22 is generated by the AC zero voltage pulse generator 17 in FIG. It is input to the washing water amount control means 16. The time tn (n=1...n) 24 from when the pulse is generated until when the trigger pulse 23 is generated is controlled. That is,
A trigger pulse 23 is generated t ₁ 24 after the AC zero voltage pulse 22, and the trigger pulse 23 is
When the power control element in the motor drive circuit 9 is ignited, the power indicated by diagonal lines 25 is supplied to the motor. Furthermore, the smaller tn24, the more power is supplied to the motor, which means that the rotational speed of the motor increases and the amount of washing water increases.

Now, if the fluctuation switch 12 is OFF,
The setting value of the washing water amount setting means 11 is AD converted, and 1
6, a trigger pulse 23 is output after a time tn24 from the zero voltage pulse according to the value, and the motor drive circuit 19 drives the motor. In this case, the time tn according to the wash water volume setting value
24, the rotational speed of the motor is constant over time as shown in FIG. If the setting value of the washing water amount setting means is changed according to the user's preference, a trigger pulse is output at a corresponding time tn24, and the rotational speed of the motor changes as shown at 26 in FIG.

By the way, when the fluctuation switch is ON, according to one embodiment of the present invention, as shown in FIG. Shake the N,
Moreover, the duration T of the fluctuation is also fluctuated. The fluctuation in the rotational speed N of the motor is, in other words, the fluctuation at time tn24. These two series of fluctuation patterns are stored in the read-only memory element of the signal generating means 15 shown in FIG. The number N and its duration T are varied. For example, in Figure 6,
The rotational speed N and duration T of the motor change as follows: N ₄ , T ₁ →N ₁ , T ₂ →N ₃ , T ₃ →N ₂ , T ₂ . Therefore, for a certain period of time when the set value of the amount of wash water is within a certain range, the amount of wash water that is stronger than the set value comes out, and for a certain time, the situation is reversed. Note that the power spectrum of these two series of fluctuation patterns is inversely proportional to the frequency.

The signal generating means has a readout storage element that stores a signal whose output power spectrum is inversely proportional to the frequency in a digital quantity, so that the signal generating means always gives a fresh, refreshing and comfortable feeling to the cleansed private part, and also has a pine surge effect. It is also perfect for pide.

Further, FIG. 7 collectively shows a flowchart of control in the above-described embodiment of the present invention.

In the above embodiment, the read-only memory element of the signal generating means 15 outputs a signal that changes the motor rotation speed N and its duration T.
The rotation speed N of the motor may be changed and the duration may be fixed to, for example, 1 second.

Effects of the Invention As described above, the sanitary washing device of the present invention includes a washing water supplying means for discharging washing water for washing private parts of the human body, a setting means for setting the water amount of the washing water supplying means, and a water quantity of the washing water supplying means. Since the configuration includes a control means for controlling the amount of water according to the establishing means, a signal generation means for causing fluctuation in output, and a control means for fluctuating the water amount of the washing water supply means in accordance with the output of the signal generation means, the following is achieved. There is an effect like.

It is possible to wash private parts while changing the amount of water with high water pressure and the amount of water with low water pressure due to fluctuations, so it is possible to improve the cleaning effect when the water pressure is high and to wash on average with softness and less pain. Even though the amount of water at the center of the fluctuation can be changed according to the user's preference, the fluctuation width itself does not change, so the feeling of fluctuation does not change, and a comfortable fluctuation feeling can always be obtained, making it easy for people with hemorrhoids. It has features that can be used.
