Supplies a high voltage to the rotation motor K so as to increase the number of rotations more than the normal rotation, and increases the amount of odor that is required to increase the number of rotations of the odor suction fan F, thereby increasing the user's It satisfies the satisfaction.

In this case, the amount of ozone generated by the ozonizer 17 can be increased together with the rotation speed of the odor fan F.

Hereinafter, a description will be given based on a schematic diagram showing a control system of the ozone deodorizing apparatus M shown in FIG.

In this embodiment, the seating sensor S1 is the toilet body A
A pressure-sensitive switch, which is interposed between the seat and the toilet seat 2, is operated and detected by the weight of the user.

However, in addition to the above, a light emitting diode and a photodiode are provided on both sides of the base of the toilet seat, and a photoelectric sensor which detects a cutoff of light between them and outputs a detection signal when the user sits down, or a user sits down. Any device that detects the user's seating, such as a capacitance-type sensor that detects a change in capacitance between the electrodes caused by the operation and outputs a detection signal, may be used.

The change switch S is provided on the left sleeve 1a of the function unit casing 1 and is connected to the fan drive unit E via the control unit D. The fan drive unit E is connected to the odor suction fan F Is connected to the rotary motor K.

The control unit D comprises a microprocessor D1, input / output interfaces D2 and D3, and a memory D4. A seat sensor S1 and a change switch S are connected to the input interface D2, and a fan drive is connected to the output interface D3. The section E is connected to the high voltage generator 19, and the memory D4 is provided with functions of the ozone deodorizer M, such as changing the number of revolutions of the rotary motor K of the odor suction fan F in response to the operation of the change switch S. Is stored.

Here, a case where the user actually uses the above-mentioned toilet seat with a deodorizing function will be described.

First, when the user sits down, the seating sensor S1
Sends a detection signal to the input interface D2 of the control unit D.
Then, by outputting a drive signal from the output interface D3 to the fan drive unit E and the high voltage generator 19 by a program incorporated in advance, the odor suction fan F starts a steady rotation by the operation of the rotary motor K, The high-voltage generator 19 starts applying the voltage to the ozonizer 17 and causes the ozone generator G to generate ozone while starting to inhale the odor in the pot A1.

Then, the odor and the ozone are mixed by the odor suction fan F to perform a deodorizing action. At this time, the catalyst H promotes the deodorizing action.

As described above, if it is desired to further enhance the deodorizing effect during the normal automatic deodorizing operation, the change switch S is turned on, and the operation signal of the switch S is input to the control unit D. In accordance with a pre-installed program, the fan drive unit E applies a higher voltage than normal to the odor suction fan F based on a signal from the output interface D3.
Is supplied to the rotary motor K as a power source for a certain period of time or until the change switch S is turned off, thereby increasing the number of rotations.

That is, as shown in the timing chart of FIG. 6, when the user sits on the toilet seat 2, the seating sensor S1 is turned on.
46, and outputs a seating signal to the control unit D, and after a time t1 sufficient to confirm that the user has certainly seated, the control unit D, which has received the seating signal, uses a program incorporated in advance to inhale odor. The rotation motor K of the fan F is started 48 at a normal rotation speed, and the ozone generator G is started 53.
Then, when the user operates the change switch S to remember the necessity, the switch S is turned on and the switch S is turned on to the control unit D
The control unit D that outputs a signal and receives the ON signal increases the number of revolutions of the rotary motor K for a certain period of time 49 according to a program incorporated in advance.

Then, the odor generated in the toilet bowl A1 is sucked into the ozone treatment flow path R earlier and more than usual.

Therefore, the deodorizing effect is much improved as compared with the deodorizing treatment by the normal automatic operation.

At this time, the amount of ozone generated in the ozone generator G is increased in accordance with the high speed rotation of the rotary motor K.
It can also be done.

That is, sufficient ozone is generated so as to cope with a large amount of odor sucked, and the effect of the deodorizing treatment is further enhanced.

Further, in the operation of the change switch S, the operation of the ozone deodorizing apparatus M can be enhanced only while the change switch S is being operated.

That is, as shown in FIG. 6, the user operates the change switch S by operating the change switch S in a state in which the seating detection sensor S1 detects the seating of the user and performs normal automatic deodorization.
When N41 is set, while the switch S is continuously operated, 43
The change switch S continuously outputs an ON signal to the control unit D, and while receiving the ON signal, the control unit D controls the rotation of the rotation motor K of the odor suction fan F by a program installed in advance. It instructs that the number be maintained at high speed rotation 49. In this case, there is an effect that the user can increase the deodorizing ability only for a necessary time.

At this time, the amount of ozone generated in the ozone generator G is increased in accordance with the high rotation of the odor suction fan F.
It can also be done.

In another embodiment, when the user is not seated, the change switch S is operated to rotate the odor suction fan F to perform deodorization. That is, the change switch S is an operation switch for operating the deodorizing device M.

That is, in FIG. 6, even when the seating sensor S1 does not detect the user's seating, the change switch S
The ON signal is output to the control section D by ON 44 of the control section D. Upon receiving the ON signal, the control section D activates the rotation motor K and the ozone generation section G of the odor suction fan F for a certain period of time 51, 56 by a program incorporated in advance. Let it.

At this time, it is preferable that the rotation of the odor suction fan F and the amount of ozone generated in the ozone generation section G are set higher than those in the automatic deodorization.

Also in this case, the operation of the ozone deodorizing device M by operating the change switch S is performed while the change switch S is continuously operated without setting a fixed time.
45 can be activated.

In the figure, t2 is the operation time of the odor suction fan F and the ozone generation unit G for sufficiently deodorizing the odor after the user leaves the seat, and the odor is maintained even after the user leaves the seat. Is in the toilet body A, and the seating sensor S1 is turned off.
It operates even if it becomes F.

Reference numerals 40 and 42 denote change switches S, 47 denotes a seat sensor S1, 50 and 52 denote odor suction fans F, and 55 and 57 denote ozone generation units G.

As described above, even when the user does not sit down,
The user can deodorize by operating the change switch S as necessary. For example, if a user feels an odor even when using a small boy, the deodorization can be performed at any time.
