[Structure of the invention]

The structure of the present invention is that a sanitary cleaning device having the functions of hot water washing and heated toilet seat, or hot water washing, hot air drying, and heated toilet seat, has a means for detecting and diagnosing an abnormality in each functional component device, and the abnormality The display is made by substituting the operation display means for each function arranged on the operation section.

〔Example〕

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

FIG. 1 is a perspective view of a sanitary washing device according to the present invention, in which 1 is a toilet bowl with a hollow bowl 1a formed inside, 2
3 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.
A control section A for controlling the temperature, operation, etc. of these devices 6, 7 and the heated toilet seat 3 is built in, and an operation section B is provided in the panel section. Further, 8 is a cleaning nozzle which is a part of the hot water cleaning device 6 and can move forward and backward in the direction of the toilet bowl 1a, and 9 is a hot air outlet provided near the nozzle 8.

In the above configuration, the temperature and operation of the heated toilet seat 3, hot water washing device 6, and hot air drying device 7 are controlled by the operating section B.
It is controlled by the control unit A according to the set value of .

FIG. 2 is a front view showing the panel section of the operation section B.
Cleaning switch S-1 that operates the hot water cleaning device 6
and a bidet switch S-2, a warm air drying switch S-3 that operates the hot air drying device 7, a stop switch S-4 that stops these operations at any time, and a water pressure adjustment volume S-7 that adjusts the washing water pressure. It is arranged for use in normal cleaning. S-5 turns on/off the heater of the hot water cleaning device 6.
A hot water heater switch S-6 is a toilet seat switch that turns on and off the heater of the heated toilet seat 3, and temperature adjustment volumes C-1 and C-6 set the hot water temperature, hot air temperature, and toilet seat temperature to arbitrary values. −
2 and C-3 are covered with a cover C ₀ and placed in a buried state.

Also, L-1, L-2, L-3, L-5 and L
-6 is an indicator light that lights up when the anus cleaning, bidet cleaning, hot air drying, hot water heater, and toilet seat heater are activated, respectively.

FIG. 3 is a block diagram showing a control system including a control section A and an operation section B. FIG. First, talking about the hot water cleaning system, the cleaning nozzle 8 communicates with a hot water storage tank 12 containing a heater 10 and a temperature sensor 11, and the hot water storage tank 12 has a solenoid valve 13 in the middle and communicates with a water supply source such as tap water. are doing. 14 is a water volume regulator provided between the hot water storage tank 12 and the cleaning nozzle 8;
The washing hot water is controlled via the temperature sensor 11 and the heater 10, and the hot water temperature is set by the hot water temperature adjustment volume C-1 of the operation section B.

The water amount regulator 14 may be provided between the electromagnetic valve 13 and the hot water tank 12. There is also a method of using a pump instead of the solenoid valve 13 and taking water from the wash water tank 2 as a water supply source. In this case, it is possible to adjust the amount of water by controlling the rotation or reciprocation of the pump.

The cleaning nozzle 8 is moved back and forth in the axial direction by the motor 15, and the anus is cleaned by operating the cleaning switch S-1.
The bidet cleaning switch S-2 is moved forward to reach the bidet cleaning position. The position sensor 16 detects the cleaning position and storage position of the cleaning nozzle 8.

Next, talking about the hot air drying system, the hot air drying device 7 includes a blowing fan 19, a heater 20 provided in the flow path, and a temperature sensor 21.
9 and the heater 20 are powered by the hot air drying switch S.
-3, and the hot air temperature is set using the hot air temperature adjustment volume C-2.

The toilet seat 3 is equipped with a heater 17 and a temperature sensor 1.
8 is installed, and the toilet seat temperature is controlled by both.
The heater 17 is energized by the toilet seat switch S-6, and the temperature is set by the toilet seat temperature adjustment volume C-.
Perform according to 3.

In addition, each switch S-1 to S-6 having indicator lights L-1 to L-6 and the stop switch S-4 are automatic return type tact switches, and each temperature adjustment volume C-1, C-2, C -3 is usually covered by a cover C ₀ .

Next, let's talk about the effect. In the block diagram of Fig. 3, if the stop switch S-4 is held down,
The clocking means M-1 starts counting, and after a certain period of time (K; in this example, k=30 seconds), the continuous operation time determining means M-2 instructs the display function switching means M-3 to switch the display. . On the other hand, failure detection means M-4
The presence or absence of a failure in each functional section is constantly detected by means of the M-5.
is memorized. A failure display signal is input to the display function switching means M-3 whose display has been switched by the failure storage means M-5, and one of the indicator lights L-1 to L-6 lights up or blinks. FIG. 4 is a flowchart for executing such control.

The location of the failure can be known by lighting or blinking the indicator lights L-1 to L-6.
When the indicator light L-3 of the hot air drying switch S-3 lights up, the hot air drying device 7 and the indicator light L-6 of the toilet seat switch S-6 light up. If this occurs, the toilet seat 3 may be configured to detect the failure location.

The failure detection means M-4 has a configuration that has been conventionally used for various types of control, and includes a control section A.
In the control system included in the control system, the presence or absence of a failure is determined by comparing each controlled element with a preset reference value. For example, when detecting a failure in the heated toilet seat 3, the temperature detected by the temperature sensor 18 is compared with a reference value, and at the same time, the activation signal of the heater 17 is also compared with the reference value (actually energized or de-energized). For example, a failure is determined when the signal deviates from a reference value. Furthermore, a configuration is adopted in which a failure condition is set in advance in the control unit A as a reference value for each controlled element, and a failure is determined when a signal from each controlled element matches this condition. You can also.

Furthermore, not only the control of the heated toilet seat 3 but also the failure of the hot water washing device 6 and the hot air drying device 7 can be determined by similar control. It is also possible to detect failures in other circuits. Note that when detecting a failure in the operation of the cleaning nozzle 8 in the hot water cleaning device 6, the position sensor 16 is used.

It should be noted that failure determination displays for detailed items such as the motor 15 of the cleaning nozzle 8 can be easily increased if lighting combinations of indicator lights L-1 to L-6 are made to correspond to each item.

〔effect〕

According to the present invention, the indicator light on the operation unit can be used as a fault indicator light with a simple operation, visual judgment is easy, and there is no need to provide a dedicated fault indicator light, and the number of parts can be reduced, so the structure is simple. It has the effect of being simple and inexpensive.
