Toilet seat device

Abstract

Provided is a toilet seat device configured to automatically control a confirmation test of a leakage current cutting-off function in order to secure the execution of a suitable leakage current cutting-off operation at a leakage current time. A main control unit (10) of a toilet seat device regularly judges whether the toilet seat device is in a using condition or not by using results detected bya sitting sensor (56) or a human body sensor (57). When the main control unit judges that the toilet seat device is not in a using condition, the main control unit makes a relay contact point (21) ina relay mechanism (20) of a leakage current cutting-off unit experimentally open and close by a relay driving unit (12) and makes a relay abnormality detecting unit (14) detect the existence or non-existence of abnormalities. Hence, the minimum necessary degree of confirmation of the leakage current cutting-off function can be carried out at a non-using time of the toilet seat device, so that thetoilet seat device can be used after a normal cutting-off operation of the leakage current cutting-off unit has been confirmed and a suitable leakage current cutting-off operation can be secured.

Description

technical field [0001] The present invention relates to toilet seat devices such as a heated toilet seat and a warm water washing toilet seat, and more particularly to a toilet seat device having an electric leakage shutoff function and a function of checking abnormality of the electric leakage shutoff function. Background technique [0002] Toilet seat devices such as heated toilet seats and warm water toilet seats are hygienic products, so they are installed in an environment where water is used. However, toilet seat devices are also electrical products, so measures against electric leakage are required, so they have an electric leakage cutoff function. Specifically, for example, a structure in which an earth leakage breaker is integrated with a power plug for supplying power to a toilet seat device, or a structure in which an earth leakage interruption circuit is included in the toilet seat device main body, etc. are known. Generally, an earth leakage breaker or an earth ...

AI Technical Summary

Problems solved by technology

If the toilet seat unit is used for a longer period of time or if it is used more frequently, the performance of the toilet seat unit itself will obviously gradually decrease

And, well-known, in the relay mechanism as representative earth leakage cut-off part, for example, if a large surge current is generated when the relay contact is closed, the possibility of welding becomes high, so the use of the toilet seat device The period and frequency of use do also affect the deterioration of the relay mechanism
