This is a storage box for storing things such as.

In the sanitary cleaning device, the user 5:
After defecating, cleansing water is released into the anus to cleanse the anus.

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 for people with hemorrhoids. In that case,
If the water pressure is lowered, the pain will be alleviated, but the 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, the present invention provides a cleaning water supply means, a water amount setting means for the cleaning water supply means, a cleaning water supply control means for controlling the water amount according to the set value, and a cleaning water supply control means that controls the amount of water according to the set value. signal generating means for generating;
A washing water control means is provided in which the amount of water in the washing water supplying means fluctuates in accordance with the output of the signal generating means, and the washing water is discharged at an amount corresponding to the washing water supplying setting means, or a range of a set value of the washing water setting means is provided. The degree of fluctuation in the output of the signal generating means is varied, and the amount of water in the cleaning water supply means is fluctuated in accordance with the fluctuation.

DESCRIPTION OF THE EMBODIMENTS The configuration of the sanitary cleaning device according to the embodiment of the present invention
This will be explained with reference to FIGS. The configuration of the conventional sanitary cleaning device shown in FIG. 1 is also applied to the present invention as is, 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 washing water amount setting means or a washing water amount setting volume,
12 is a switch that gives fluctuations to the washing water. 13 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, 1
Reference numeral 4 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; 16 is a control means for controlling the water amount according to the washing water amount setting means 11;
(In this example, the microcomputer) When the fluctuation switch 12 is ON, the signal generating means 15
The washing water supply control means receives the signal and controls the rotation speed of the motor 9. 17 is an AC zero voltage pulse generator, 18 is an AD circuit that converts 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.
Conduction angle θn every 0 half cycles (n=1, 2...)
21 to adjust the electric power (in the embodiment of the present invention, the rotation speed of the motor is controlled).

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, the trigger pulse 23 is generated t ₁ 24 after the AC zero voltage pulse 22, and the trigger pulse 23
When the power control element in the motor drive circuit 19 is ignited, the motor is supplied with the power indicated by diagonal lines 25. 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, when the fluctuation switch 12 is OFF, the setting value of the washing water amount setting means 11 is AD converted,
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 tn2 according to the washing water volume setting value
4 is always output, so the rotational speed of the motor is constant over time as shown in FIG. In addition,
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. 5.

By the way, when the fluctuation switch is ON, according to the embodiment of the present invention, as shown in FIG. The number N is fluctuated, and the duration T of the fluctuation is also fluctuated. The fluctuation in the rotation speed N of the motor is 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, when the set value of the amount of washing water is low as shown in FIG. 6a, the rotational speed N of the motor and its duration T fluctuate between the set values based on NO. However, if the set value of the amount of cleaning water is strong as shown in Figure 6b, for example, the cleaning water is adjusted so as to give a fluctuation of the motor rotation speed N that is twice that of Figure 6a between the set values based on No. Controlled by water supply control means.

The rotation speed N of the motor and its duration T in Fig. 6a are (N ₂ ′, T ₁ ) → (N ₄ ′, T ₂ ) → (N ₃ ′,
T ₁ ) (N ₄ ′, T ₁ ) → (N ₁ ′, T ₃ )... but in Figure 6-B, (N ₂ ″, T ₁ ) → (N ₄ ″, T ₂ ) → (N ₃ ″，
T ₁ ) → (N ₄ ″, T ₁ ) → (N ₁ ″, T ₃ )…, Nn″=k Nn′ n=1, 2, 3, 4…(1) It is controlled by the following relationship. In this example, the case is k = 2.In other words, the washing water amount is set based on the motor rotation speed No. out of the two fluctuation patterns of the motor rotation speed N and its duration T in Fig. 6a. The degree of fluctuation in equation (1) varies in the range of the setting value of the means.In other words, between No and the setting value, fluctuations in the motor rotation speed N do not occur much in the weak vicinity, and in the strong vicinity Then, it will fluctuate violently.

Note that the power spectrum of these two series of fluctuation patterns is inversely proportional to the frequency. The signal generating means has a read-only storage element that stores a signal whose output power spectrum is inversely proportional to the frequency in a digital quantity.
It always gives a fresh, refreshing and comfortable feeling to the cleansed private parts, has a pine surge effect, and is also ideal for bidets.

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 rotational speed N of the motor may be changed and the duration may be fixed to 1 second, for example.

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 setting means for setting the water amount of the washing water supplying means. The configuration includes a control means for controlling the amount of water in accordance with the means, a signal generation means for causing fluctuations in the 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, as follows. There is an effect. 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. Moreover, the water volume setting value, which determines the maximum amount of fluctuating water volume, can be set arbitrarily according to the user's local condition, and as the setting value is lowered, the fluctuation width also becomes smaller, so it does not cause anxiety to people with severe hemorrhoids. It has the feature that it can be solved.
