DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat with a deodorizing function.

[0002]

2. Description of the Related Art Conventionally, in a toilet seat having a deodorizing function, a seating sensor is provided on a toilet seat or the like, and when a seating of a user is detected, an odor suction fan is rotated by a seating detection signal of the seating sensor to automatically operate a deodorizing device. The odor generated in the toilet body is automatically deodorized using a deodorant or ozone.

[0003]

However, such a toilet seat with a deodorizing function is configured to detect that a user is seated, and to activate the deodorizing device in response to the seating signal. Has only the operating categories of ON and OFF, and since the operating amount of the odor suction fan is set in advance, it has only a constant suction force and deodorizing power.

Therefore, the odor generated in the toilet varies from person to person, and varies depending on the physical condition of the user. Therefore, such a constant suction force and deodorizing power are not sufficient for the comfort between individuals. The satisfaction was not satisfied.

[0005] Furthermore, if the user does not sit down, deodorization is not performed, and deodorization cannot be performed at an arbitrary time, which is inconvenient for the user.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a seat detecting means for detecting a user's seat, and an odor inhaling means for inhaling odor in a toilet body by detecting the seating of a human body on a toilet seat from the seat detecting means. In the toilet seat with a deodorizing function having a deodorizing device for operating the deodorizing device, the deodorizing device can change the operation amount of the odor inhaling means by the operation of the user,
The present invention provides a deodorant-equipped toilet seat including a change switch for enabling the operation of the odor inhaling means to be started when the seat detecting means has not detected a user.

That is, the deodorization can be performed by operating the change switch not only when the seat is detected but also when the seat is not detected, and the user can deodorize as needed at any time.

The deodorizing device M is interposed between them.

In the above configuration, the deodorizing device M will be described with reference to FIGS.

The deodorizing device M comprises an ozone generating section G, an odor suction fan F and a catalyst H. The ozone generator G, which constitutes a part of the deodorizer M, is disposed at the center of the rear of the deodorizing duct 7, and the ozone generator G is attached to the heater 18 and the side surface of the heater 18.

The ozonizer 17 is connected to a high voltage generator 19 disposed in the chamber case 11, and the high voltage generator 19 is connected to a control unit D (FIG. 2). The ozone can be generated in the deodorizing duct 7 by applying a high voltage to the ozonizer 17 from the high voltage generator 19 based on the drive output from the OLED.

The ozonizer 17 is connected to a seating sensor S1, which will be described later, via a control unit D. The control unit D receives a seating detection signal of the seating sensor S1, and outputs a driving signal output from the control unit D. It operates to generate ozone based on the

The heater 18 heats the ozonizer 17 to promote the generation of ozone by the ozonizer 17.

An ozone treatment channel R is formed downstream of the ozone generating section G, and an odor suction fan F is provided above the ozone processing channel R.

The ozone treatment channel R is provided in a chamber case.
Inside 11 is formed in a vertically extending hollow casing 20, the upper part of which is in communication with the interior space of the deodorizing duct 7.

It is characterized in that an arbitrary conversion of the number of rotations is possible.

That is, when the seating of the user is detected by the seating sensor S1, the deodorizing device M automatically operates to perform deodorization. Next, when the user operates the change switch S as necessary, the control unit D receiving the signal from the change switch S
Outputs a signal to the fan drive unit E,
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 will satisfy you.

At this time, 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 functional 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-described 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, and a deodorizing action is performed. At this time, the catalyst H promotes the deodorizing action.

As described above, when 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 from the switch S 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 channel R earlier and in a larger amount than usual.

Therefore, the deodorizing effect is much improved compared to the deodorizing process 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 can be generated to cope with a large amount of odor sucked, and the effect of the deodorizing treatment is further enhanced.

In the operation of the change switch S, the ozone deodorizing device M can be operated while the capacity thereof is increased only while the change switch S is operated.

That is, as shown in FIG. 6, in a state where the seat detection sensor S1 detects the seating of the user and the normal automatic deodorization is being performed, the user operates the change switch S to change the O.
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.

Further, when the user is not seated, the odor suction fan F can be rotated by operating the change switch S to perform deodorization.

That is, in FIG. 6, even when the seat sensor S1 does not detect the user's seat, 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 by the ozone generating section G are set to be higher than those at the time of 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.

Note that 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 OFF timings of the ozone generator 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.

[0061]

According to the present invention, a change switch capable of converting the rotation speed of an odor suction fan into a toilet seat with a deodorizing function configured to detect a user's seat and automatically perform a deodorizing process. By providing a odor, each user can perform a satisfactory deodorization by operating the change switch for odors that are originally different from each other, and the usability as a toilet seat with a deodorization function is significantly improved. Can be.

Further, even when no seat is detected,
Since the deodorization can be performed by operating the change switch, the user can perform the deodorization whenever necessary. in this way,
The operability is extremely good because the deodorizing action amount can be changed and the deodorizing operation can be started with one change switch.

When the deodorizing operation time by operating the change switch is set to a predetermined time, the necessary deodorization can be performed only by operating the change switch once, and the operation is easy for the user, and the change switch is operated. If the operation is continued while the operation is continued, the user can perform the deodorization according to the actual need, which is very reasonable.
