Description

[Detailed description of the device] << Industrial application field >> The present invention relates to a deodorizing control device installed in a Western-style toilet,
In particular, the operation time of the deodorizing fan is controlled according to the frequency of use of the toilet.

<Prior Art> Conventionally, as described in Japanese Utility Model Publication No. 61-8148, this type of deodorizing device is a resettable that drives the deodorizing fan of the deodorizing device for a certain delay time after the toilet user stands up from the toilet seat. It was equipped with a timer switch.

That is, this resettable timer switch has a seating sensor function, and this seating sensor function will be described with reference to FIG.

The symbols A to H shown in FIG. 8 indicate operating points of the seating sensor.

When the toilet is used less frequently between A and D, the user sits on the toilet seat at point A, the seating sensor is turned ON, and the motor that operates the deodorizing fan is turned ON to start the deodorizing operation. Then, at point B, the user stands up and the seating sensor
At the same time as turning off, the motor turns off at point C when a predetermined delay time T ₁ has passed from point B, and the deodorizing operation ends.

Toilet is used more frequently between D and G continuously, that is, the user sits on the toilet seat at point D and stands up at point E, and the time T ₂ (T ₂ <T ₁ ) shown between EF is reached. This is a case where the next user sits on the toilet seat at point F and stands up at point G after the elapse of time.

At this time, the user sits on the toilet seat at point D, the seating sensor turns on, and the motor that operates the deodorizing fan turns on,
Even if the seating sensor is turned off while the toilet user is changing at time T ₂ shown between EF, this time T ₂ is T ₂ <T ₁ (delay time), so the motor continues to be in the ON state and at the point G When the next user stands up and the seating sensor is turned off,
The motor is OF at the H point when the predetermined delay time T ₁ has passed from the G point.
It becomes F and functions to end the deodorizing operation.
