Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush toilet bowl. More specifically, the present invention relates to a flush toilet and various electric devices provided in a warm water washing device integrally installed on the upper rear portion of the body of the flush toilet, independent from a single input terminal. The present invention relates to a flush toilet that can supply power to the toilet.

[0002]

2. Description of the Related Art Conventionally, various improvements have been made to the functionality of flush toilets, for example, those of a type in which flush water is directly supplied to a toilet bowl from tap water, and filth. The applicant of the present application has already proposed a system in which the flapper valve provided in the drainage channel is used to open and discharge the above.

In addition, the flush toilet is not only improved in its own functionality, but is also improved in total aspects in using the toilet, such as convenience and hygiene, and various functions are added. . For example, as an example thereof, hot water washing devices capable of washing hot water locally have been provided as toilet seat units and the like.

In the hot water washing device, tap water is heated in a hot water tank, and hot water for local washing can be jetted from a jet nozzle according to an input from an operation switch. Such hot-water washing devices further include a drying device for drying local parts after hot-water washing, a deodorizing device for removing odors from filth generated by using a toilet, and a toilet for winter. Occasionally, a toilet seat heating device that heats the toilet seat, a warm air heating device that heats the inside of the toilet room, etc. may be installed together.

[0005]

However, while such high functionality is advanced, the number of electric devices provided in the flush toilet bowl and the hot water washing device is also increased, which is not recognized in the past. Such technical problems are occurring. For example, in order to further simplify the circuit configuration of electrical equipment, etc., a single outlet should be used to supply power to the flush toilet and various electrical equipment installed in the hot water washing device, as well as the control device that controls their operation. It is also considered to be carried out by one system via.

However, in this case, when one of the flush toilet and the hot water flush device fails, the other device is not supplied with power, and when the power supply to the control device is cut off, the flush toilet and There is a problem that both of the hot water washing devices do not work. For example, if the hot water cleaning device fails due to TRS abnormality, electric leakage from the sheathed heater, etc., despite the failure of only the hot water cleaning device,
In the flush toilet, it becomes impossible to discharge the waste and the like after using the toilet. The filth emits an odor, and this situation must be avoided from the viewpoint of hygiene. The inability to discharge dirt and the like from the flush toilet also occurs when the hot water washing device is operated in the power saving mode.

Recently, attempts have been made to provide the flush toilet itself with a local hot water washing function, and a new type flush toilet integrated with a hot water washing device is being developed. In a flush toilet having such a hot water washing function, the above-mentioned problems are particularly manifested. The present invention has been made in view of the above circumstances, and is installed in a flush toilet and a hot water washing device in a flush toilet integrated with the hot water washing device .
Eliminating the drawbacks of the power supply to various electric devices, various electric devices provided in the flush toilet bowl and bidet equipment,
It is an object of the present invention to provide a flush toilet bowl that can supply power independently from a single input terminal.

[0008]

In order to solve the above-mentioned problems, the present invention provides a flush toilet and various electric devices provided in a hot water washing device integrally installed on the upper rear portion of the body of the flush toilet.

In the control device (46), power is supplied to the control circuit section (A), the flush toilet drive circuit section (B) and the hot water cleaning device drive circuit section (C).
Provide only one input terminal (60) to connect to commercial power,
A control circuit unit (A), a flush toilet drive circuit unit (B), and a hot water washing device drive circuit unit (C) are connected to the input terminal (60) as separate systems. A transformer (61) is provided between the input terminal (60) and the control circuit section (A).
Further, a power supply relay (62) is interposed between the hot water cleaning device drive circuit section ( C ) and the input terminal (60).

As described above, power is supplied to the control circuit section (A), the flush toilet drive circuit section (B) and the hot water washing device drive circuit section (C) from the single input terminal (60) in different systems. Even if either the flush toilet (1) or the hot water washing device (2) fails, the power is supplied to the drive circuit section of the other device in the same manner as before. You can Further, even if the power supply to the control device (46) is cut off, the power is supplied to both drive circuit parts of the flush toilet bowl (1) and the hot water cleaning device (2).

In the unlikely event that the hot water washing device (2) fails due to TRS abnormality, electric leakage from the sheathed heater, etc., the drive circuit section (B) of the flush toilet bowl (1) is not powered. The water supply valve solenoid (17) and the flapper valve motor (53) that are supplied can be operated, and filth and the like after using the toilet can be reliably discharged. This is the same when the hot water washing device (2) is operated in the power saving mode. No waste is left as it is after using the toilet.

Further, as shown in FIG. 8, the controller (4
The room temperature thermistor (50) electrically connected to 6) is
In order to improve the detection accuracy, the hot water cleaning device (2) is arranged so as to project outside the rear portion of the main body. Similarly to this, the room temperature thermistor (50) is protected by a protection member (63) projecting outside the rear part of the main body of the hot water cleaning device (2). Moreover, room temperature thermistor (50)
In the vicinity of the hot air heating device (36) and the drying device (4
An outside air inflow hole is formed to take in outside air when 3) is activated.

Hot air heating device (36) and drying device (4
In the room temperature detection during operation 3), there is a temperature difference between during and after the intake of outside air. In order to detect the room temperature in a state closer to the environment in the toilet room, the temperature detection during intake is better. It is suitable. Therefore, as described above, by disposing the room temperature thermistor (50) in the vicinity of the outside air inflow hole of the main body of the hot water cleaning device (2) and outside the main body of the hot water cleaning device (2), the outside air temperature during suction can be controlled. It can be measured, and the detected temperature is close to the room temperature in the toilet room. As a result, the operation control by detecting the room temperature of the warm air heating device (36) and the drying device (43) becomes more practical.

The location of the room temperature thermistor (50) is not limited to the main body of the hot water cleaning device (2), but may be the main body of the flush toilet bowl (1). Also in this case, the room temperature thermistor (50) can be provided in the rear part of the flush toilet (1) in the vicinity of the outside air inflow hole so as to project to the outside. Of course, the present invention is not limited to the above examples. There are various possible configurations of the details of the toilet bowl and the hot water washing device. For example, the hot water washing device can be of a type that is installed as a toilet seat unit separately from the flush toilet and installed above the toilet bowl.
