Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a sanitary cleaning device that uses cleansing water to cleanse private parts after using the toilet.

2. Prior Art A conventional sanitary cleaning device of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 58-1
As shown in Japanese Patent No. 60449, it had a structure as shown in FIG.

That is, in FIG. 8, 1 is the main body and 2 is the toilet seat. Inside the main body 1, there is a pump 3 as a pressurizing device, and the cleaning water pressurized by the pump 3 passes through a tank 4 and a nozzle 5.
Clean the private parts by squirting more water. 6 is a hose.

FIG. 9 is a block diagram of the water circuit, and the same parts are given the same numbers as in FIG. 8. 7 is a distern, and 8 is a solenoid valve.

FIG. 6 is a detailed view of the tank 4. 9 is the water inlet, 10
1 is a water outlet, 11 is a heater, and 12 is a temperature sensor that controls the temperature of hot water in the tank 4.

FIG. 7 is a circuit diagram for controlling the temperature of hot water in the tank 4.

The temperature of the water is controlled by controlling the supply of electricity to the heater 11 using a temperature sensor 12.

Problems to be Solved by the Invention However, in this configuration, the temperature of the hot water in the tank 4 is always controlled to be around the optimum cleaning temperature of 40°C. However, in a typical household, sanitary washing equipment is used only a few times, so power is energized to the heater 12 for approximately 23 hours a day to maintain the optimum water temperature for the next use of washing water, which reduces power consumption. There was a problem with loss. Therefore, the present invention aims to reduce the power consumption when controlling the temperature of the tank with a simple structure, and also to enable cleaning at a comfortable water temperature.

The means to solve the problem and the technical means to solve the above problem are to set the control means for controlling the temperature of hot water in the tank at the optimum cleaning temperature and a lower temperature, and to select that setting with a switch. Furthermore, when the valve seat is detected to be seated, the temperature is automatically set to the optimum temperature.

action The effect of this technical means is as follows.

In other words, when the machine is not in use, the water temperature in the tank is controlled at a temperature lower than the optimum temperature for washing, the water temperature is raised to a certain degree, and when the machine starts to be used (seated), the water temperature control setting is automatically set to the optimum temperature for washing. It boils quickly. Therefore, the power consumption of the tank heater when not in use can be significantly reduced. In addition, in general households, water is often used continuously in the morning, so if you set the hot water temperature setting selection switch to the optimum temperature for washing at that time, it will always be at that temperature, so you can comfortably use it continuously. Can be washed.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 3, 20 is a toilet bowl, 21 is a main body installed on the toilet bowl, 22 is a toilet seat, 23 is a nozzle, 24 is a power switch, 25 is a cleaning knob, 26 is an energy dissipation knob, and 27 is a hot water temperature adjustment knob.

FIG. 4 is a water circuit diagram, in which 28 is a cistern, 29 is a solenoid valve, 3o is a pump, 31 is a tank, and a hose 32 connects each of them.

FIG. 1 is a detailed diagram of the inside of the tank 31, in which 33 is a water suction pipe, 34 is a water inlet, 35 is a water outlet, 36 is a heater, and 37 is a water intake pipe.
3 is a temperature sensor to control the temperature of the washing water in the tank to the optimum temperature for washing, and 3 is a thermostat to control the temperature to a lower temperature.

FIG. 2 is a hot water temperature control circuit diagram, and 39 is a seat switch that detects whether a person is sitting.

Next, the operation of the configuration of this embodiment will be explained.

When the IC source switch 24 is turned on, the heater 36 is energized as shown in the control circuit diagram of FIG.
The water temperature is controlled at ~42°C.

When the energy extinguishing switch 26 is on, the thermostat 38 controls the water temperature to be 5 to 10 degrees Celsius lower than the optimum cleaning temperature. When not in use, the energy saving isostatic switch 26 is turned on to save energy, and hot water is stored in the tank 31 at a temperature 5 to 10 degrees Celsius lower than the optimum cleaning temperature.

This reduces energy consumption by approximately 20% compared to conventional methods.

In FIGS. 4 and 5, when the user sits on the toilet seat 22, the seat switch 39 is turned on, and the temperature sensor 37 sets the optimum washing temperature to be set 5 to 10 degrees Celsius lower than the optimum washing temperature set by the thermostat 38. , heater 36
The water is energized and heated to the optimum temperature for cleaning. In FIG. 5, reference numeral 40 indicates a change in the hot water temperature in the tank 33 when the energy extinguishing switch 26 is off, and 41 indicates a change in the hot water temperature in the tank 33 when the energy extinguishing switch 26 is on.

When the user turns the cleaning knob 25 after defecating, the electromagnetic valve 29 is turned on to open the waterway, the pump 30 rotates, the cleaning water is pressurized, and the cleaning water is sent to the tank 31. Water inlet 3 in Figure 1
Pressurized cleaning water enters tank 3 as shown by the arrow.
The space inside 1 is pushed up, hot water comes out from the drain port 35, and washing water is jetted out from the nozzle 23, allowing private parts to be washed.

When the toilet is used a lot in the morning, there is a large amount of hot water, so if the energy extinguishing switch 26 is turned off, the water is always boiling at the optimum temperature for washing, and the user can immediately wash at a comfortable temperature.

Effects of the Invention In the present invention, the water temperature in the tank can be set between the optimum cleaning temperature and a lower temperature, and the setting can be selected with a switch, and when the user is seated, it is automatically set to the optimum cleaning temperature, so the following effective.

(1) Since the water temperature in the tank is controlled at a low temperature when not in use, power consumption can be significantly reduced.

(2) It has a switch that allows you to select the hot water temperature setting, so when you use it a lot in the morning, you can wash as many times as you like by controlling the water temperature in the tank to the optimum temperature for washing.
