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 that detects the popularity of the water heater, and a control unit controls the supply of electricity to the heater to provide hot water at a comfortable temperature. In addition, safety devices such as temperature fuses are installed to prevent the lightning from reaching high temperatures.

However, if a control element etc. is damaged or malfunctions, resulting in a short circuit, it may take some time for the safety device to start operating.
There is a problem in that the continued operation of the heater generates a large amount of heat, causing dangerous high-temperature cleaning water to be discharged.

[Object of the Invention] An object of the present invention is to prevent overheated high-temperature washing water from being discharged when an abnormality occurs in the washing water heating system.

[Structure of the invention]

The structure of the present invention is that in a sanitary washing device equipped with a hot water washing function that sprays hot washing water to private parts, an overtemperature detection means is provided in a control section that controls energization to a heater of a water heater, and when the washing water is detected to be at an abnormally high temperature. When this happens, the wash a1 water flow path is closed to stop water spouting.

〔Example〕

The present invention will be explained below 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 (
1) is a toilet with a toilet bowl (la) inside, (2) is a wash water tank, (3) is a heated toilet seat, and (4) is a toilet lid.

Furthermore, (5) is the sanitary washing device main body, which has a hot water washing device (6) and a hot air drying device (7) inside, as well as the temperature and various operations of these devices (61, (71) and the heated toilet seat (3). It has a built-in control part (A) for controlling the toilet, and an operation part (B) is provided in the panel part.In addition, (8) is a part of the hot water washing device (6) and is installed in the direction of the toilet bowl (1a). The washing nozzle (9) is movable back and forth, and the hot air outlet (9) is 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 section (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 cleaning device (6) system, where 00) in the figure is a water heater equipped with a temperature sensor (11) and a heater (12), and the water heater 00) has a solenoid valve ( 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) is moved forward and backward in the direction of the toilet bowl (1a) by an electric motor (14), and can spray cleaning water at each of two cleaning positions.This position detection and the storage position are detected by a position detection sensor ( 15).

This solenoid valve (13) and electric motor (14) are connected to the operating section (I
3), the first control means (11-1) of the control unit (A) receives the signal from the position detection sensor (15).
Its operation is controlled by .

The heater (I2) is connected to the second control means (M-) of the control section (A).
2), the electricity supply is controlled so that the temperature is suitable for washing, and the washing water in the water heater 00) is kept at a comfortable temperature at that time.

(16) is a burn prevention temperature (in this example, 4
This is an overtemperature detection means that detects that the cleaning water has been heated above 5℃), and its output signal enters the first control means (G1) of the control section (Δ) and closes the solenoid valve (13). controlled so that

To describe the operation by the above control system, the operation section (B)
If you turn on the cleaning switch (S-, 1), the electric tJ31
．． (14) causes the cleaning nozzle (8) to advance, and the first control means (T1) of the control section (A) receives a signal from the position detection sensor (15) and stops at the cleaning position. Next, the electromagnetic valve (13) opens and the cleaning water flows into the water heater (10), and hot water heated by the heater (12) is jetted out from the cleaning nozzle (8) for cleaning. .

The hot water in the water heater 00) is heated by the temperature sensor (11) and the control unit (
The second control means (G2) in A) controls the energization of the heater (12), giving the hot water enough heat to maintain a comfortable temperature and prevent it from becoming extremely low or abnormally high. .

Here, it is assumed that the control element of the second control means (G2) of the control unit (A) is damaged or malfunctions and short-circuited, making it impossible to control the energization of the heater (12). In this state, since the heater (12) continues to be energized, the amount of heat generated increases, and the temperature of the cleaning water gradually rises. The overtemperature detection means (16) is activated by the output signal of the temperature sensor (11) when the cleaning water temperature reaches 45°C, and the control unit (A)
The solenoid valve (13) can be closed through the first control means (1).

Therefore, the cleaning hot water from the cleaning nozzle (8) is at a maximum of 45°.
C, overheated hot water will not be discharged and can be used safely.

FIG. 3 is a flowchart for executing the control system for closing the electromagnetic control valve based on this overtemperature detection.

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

〔effect〕

The present invention has the effect that when the cleaning water in the water heater becomes overheated, the flow path to the cleaning nozzle can be immediately closed, and the high temperature cleaning water can be used safely without being discharged. .
