Description of the Related Art Conventionally, in a sanitary washing device for washing a human body with warm water, the water supply control means is kept in a water supply state until the full water detection means detects full water. This is because when the sanitary washing device is installed or when the washing water storage means is reused after draining the washing water storage means, the washing water storage means is automatically filled with water after the power is turned on.

On the other hand, when the flush water storage means is automatically filled with water, the following problems occur.

In the case of a sanitary washing device installed in a moving body such as a camping car, if the vehicle is parked under the hot sun in the summer, the water in the pipe connected to the hot water washing device becomes hot, and even if the washing water is stored. Even if the water is drained from the cleaning means, high-temperature water flows into the cleaning water storage means during the process of filling up the water, and the control means receives a signal from the cleaning water temperature detection means so that the control means cleans the sanitary cleaning device for safety. You will disable the feature.

[0005]

However, even if the temperature inside the moving body is brought to room temperature by the cooling means such as the air conditioner of the moving body and the water temperature in the wash water storage means of the sanitary washing device becomes an appropriate temperature, the sanitary condition is maintained. Since the cleaning function of the cleaning device remains disabled and the user needs to cancel the disabled state of the cleaning function, such as resetting the power source of the sanitary cleaning device, it is inconvenient for the user.

The present invention is intended to solve such a problem, and by automatically canceling the disabling of the cleaning function due to a temporary high temperature state after the power supply of the sanitary cleaning device is turned on, It is an object of the present invention to provide a sanitary washing device that releases the disabled state of the washing function without bothering hands.

When the temperature is high, the water supply state is kept constant for a certain period of time even after the full water detection means for detecting full water in the wash water storage means detects full water. As a result, even if high-temperature water heated in a part of the pipe in the moving body flows into the wash water storage means of the sanitary washing device, the water is continuously supplied for a certain period of time. It is possible to prevent the control means from disabling the cleaning function of the sanitary cleaning device for safety reasons.

[0008] According to a second aspect of the present invention, wash water storage means for storing wash water, full water detection means for detecting full water in the wash water storage means, and water supply from the water supply port to the wash water storage means are controlled. To control the water supply control means according to the output of the full water detection means, and the wash water temperature detection means, In a sanitary washing device having a control means for stopping water supply when a high temperature above a set value is detected, when the temperature detected by the wash water temperature detecting means is a high temperature above a set value, the flush water storage means is full of water. Even after the full water detection means for detecting is detected to be full, the water supply state is maintained until the temperature detected by the wash water temperature detection means becomes equal to or lower than another set value. As a result, even if the high temperature water heated in a part of the pipe in the moving body flows into the cleaning water storage means of the sanitary cleaning device, the temperature detected by the cleaning temperature detection means becomes the value set to the second value. Since the water continues to be supplied, it is possible to prevent the control means from disabling the cleaning function of the sanitary cleaning device for safety.

According to a third aspect of the present invention, in the sanitary washing device according to the second aspect, the temperature detected by the wash water temperature detecting means is
It is characterized in that the water supply state is stopped after the elapse of the set constant time even if the value does not fall below the set value. As a result, high-temperature water heated in a part of the pipe in the moving body flows into the wash water storage means of the sanitary washing device, and even if the temperature detected by the wash temperature detection means does not fall below the set value, Since the water supply is stopped at, it is possible to prevent a large amount of water in the moving body from being wasted.
