Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a sanitary cleaning device for cleaning private parts.

[Prior art]

Conventionally, a sanitary cleaning device has a configuration including a cleaning nozzle that sprays warm water to clean private parts, and hot water is supplied to the cleaning nozzle by a water heater in the hot water cleaning device. The water heater is equipped with a heater and a temperature sensor, and a semiconductor switch in the control section receives a signal from the temperature sensor and controls power supply to the heater to supply hot water at a comfortable temperature.

However, when a short-circuit failure occurs in the semiconductor switch, the heater continues to be energized and the hot water in the water heater is overheated, resulting in dangerously high-temperature cleaning water being discharged.

In order to prevent overheating during such field lightning, some devices are equipped with safety devices such as temperature fuses, but it takes time for these safety devices to operate after a short circuit failure.
The drawback is that the cleaning water is discharged at a temperature higher than the set temperature, making it unsafe to use.

[Purpose of the invention]

The present invention provides cleaning equipment that is
The purpose is to prevent water from being discharged.

[Structure of the invention]

The structure of the present invention is that a sanitary cleaning device equipped with a hot water cleaning function that sprays hot cleaning water to private parts is provided with short-circuit detection means for a semiconductor switch in a control section that controls energization to a heater of a water heater. The detection means is used to stop the discharge of cleaning water.

〔Example〕

The present invention will now be described based on embodiments shown in the drawings.

FIG. 1 is a perspective view of a sanitary cleaning device according to the present invention, and in the figure (
11 is a toilet bowl with a toilet bowl (la) formed therein, (2) is a flush water tank, (3) is a heated toilet seat, and (4) is a toilet lid.

Furthermore, (5) is a sanitary cleaning device main body, which has a hot water cleaning device (6) and a hot air drying device (7) inside, and both of these devices <61. (7+) and a built-in control unit (A) that controls the temperature and various operations of the heated toilet seat (3), and the panel section is equipped with an operation unit (B). 6) is a cleaning nozzle that can move forward and backward in the direction of the toilet bowl (1a), and (9) is a warm air outlet provided near the nozzle (8).

In the above configuration, a heated toilet seat (3), a hot water washing device (6)
) and the hot air drying device (7), the temperature and various operations are controlled by the operation section (
It is controlled by the control unit (A, ) according to the set value of B). In addition, the hot air drying device (7) and heated toilet seat (3) can be installed freely.

Figure 2 is a control block diagram of the hot water washing device (6) thread, where 00) in the figure is a water heater equipped with a temperature sensor (11) and a heater (12), and the water heater α0) has a solenoid valve in the middle. (13)
is provided to communicate with a water supply source such as tap water, and the heated cleaning hot water is fed toward the cleaning nozzle (8). The cleaning nozzle (8) can move forward and backward in the direction of the toilet bowl (1a) by means of an electric motor (<14), and can spray hot water for each cleaning at the -washing position or the second washing position, and this position detection and storage position detection This is performed by a position detection sensor (15).

The solenoid valve (13) and the electric motor (14) receive a signal from the operating section (B), and are controlled by the first control means (T1) of the control section (A) in response to a signal from the position detection sensor (15). Actuation is controlled.

The heater (12) is connected to the second control means (T2) of the control section (A).
) is connected to the semiconductor switch (16) built in the temperature sensor (II) and the second control means (
In step 2), the energization is controlled so that the temperature is suitable for cleaning.

Furthermore, (17) is a 9, +7 circuit detection means for detecting a short circuit in the semiconductor switch (16), and its output signal is transmitted to the control unit (
Δ) into the first control means (M-1), and the solenoid valve (13
) is controlled to close the valve.

” To describe the operation by the control system described in Section 2, the operation section (B
) If you turn on the cleaning switch (S-1), the electric motor (14
), the cleaning nozzle (8) advances, and the signal from the position detection sensor (15) is transmitted to the first control means (A) of the control section (A).
1) and stops at the cleaning position. Next, @ solenoid valve (1
3) is opened to allow cleaning water to flow into the water heater αψ, and hot water heated by the heater (12) is jetted out from the cleaning nozzle (8) for cleaning.

The temperature sensor (11) and the second control means (of the control section (A))
2) controls the energization of the heater (12) to provide an amount of heat that will bring the water to a comfortable temperature in the water heater 00), thereby preventing it from becoming abnormally low or extremely high.

Here, if the semiconductor switch 16) is short-circuited,
The short circuit detection means (17) operates, and the solenoid valve (13) can be closed through the first control means (T1) of the control section (Δ). Therefore, the discharge of cleaning water from the cleaning nozzle (8) is stopped L7, and the cleaning water that has been continuously energized to the heater (12) due to a short circuit is not discharged and can be used safely. FIG. 3 is a flowchart 1 for controlling the closing of the electromagnetic valve (the α11 system) by detecting this short circuit.

In the above embodiment, the solenoid valve (13) is used as the water supply opening/closing means, but a pump may be used with the wash water tank (2) as the water supply source. In addition, although the electric motor 14) is used as the means for advancing and retracting the cleaning nozzle (8), it is also possible to use water pressure.
Furthermore, the position detection sensor (15) can be freely installed.

〔effect〕

Even if a short-circuit accident occurs in the semiconductor switch of the control element that controls energization to the heater, the present invention can immediately close the flow path to the cleaning nozzle, preventing abnormally high temperature cleaning water from being discharged, resulting in safety. It has the effect that it can be used for.
