Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device in a toilet.

[0002]

2. Description of the Related Art Conventionally, in order to deodorize the inside of a toilet, a ventilation fan C is used to exhaust the odor of the toilet A to the outside of the toilet as shown in FIG. The convection was carried out in the toilet A and the deodorizing equipment D using activated carbon etc. was used to deodorize.

[0003]

In the deodorizing method shown in FIG. 3, it is necessary to attach a ventilation fan to the toilet A, and the odor is discharged to the outside of the toilet A. Is annoying. Alternatively, in the well-sealed toilet A, even if a ventilation fan is used, new outside air cannot be taken in, so that the air in the toilet becomes thin. There is also the trouble of having to process the toilet to install the ventilation fan. The method of FIG. 4 deodorizes the odor that has once flown out of the toilet B into the toilet A, so it takes time to be sufficiently deodorized, and when a person enters the toilet A continuously, The odor of may remain. Although activated carbon has excellent deodorizing power, its adsorption power is limited. Therefore, in the case of FIG. 4, the activated carbon must be frequently replaced, and its maintenance and management are troublesome. Further, there is a drawback that if the air in the toilet A is sufficiently convected to enhance the deodorizing effect, the deodorizing device itself becomes large.

[0004]

It is an object of the present invention to eliminate the need to process a toilet for installation, to efficiently deodorize in a short time, and to be small in size, without requiring a troublesome operation in use, and to be sufficiently used in the toilet. It is to provide a deodorizing device that does not cause trouble to nearby deodorized people.

[0005]

A deodorizing apparatus for a toilet according to claim 1 of the present invention comprises an air intake portion 1 attached to a toilet bowl B,
A fan 2 for sucking the air in the toilet bowl B from the intake part 1, an ozone generator 3, a deodorant material 4 such as activated carbon, and an exhaust part 5 for exhausting deodorized air into the toilet A are provided. It is a thing. In the deodorizing device in the toilet according to claim 2 of the present invention, the deodorizing device according to claim 1 detects the human body approaching the toilet bowl B and weakly operates the fan 2 to detect that the human body has left the toilet bowl B. The detection and control circuit 6 is incorporated to detect and operate the fan 2 strongly, and to automatically stop the fan 2 after a lapse of a certain time after the person leaves the toilet bowl B. In the deodorizing device in the toilet according to claim 3 of the present invention, the deodorizing device according to claims 1 and 2 is provided with a fan control circuit for operating the fan 2 for an arbitrary time every time without detecting a human body. It's complicated.

[0006]

In the deodorizing apparatus according to claim 1 of the present invention, the odorous air in the toilet bowl B is sucked by the fan 2 from the intake portion 1 attached to the toilet bowl B, and the deodorizing apparatus 8 in the deodorizing apparatus 8 passes through the tube 7. It is guided to the air tank 9. The air is primarily deodorized by the ozone generator 3, then deodorized by the deodorant material 4, and discharged into the toilet A from the discharge unit 5. In this case, the primary deodorization by the ozone generator 3 reduces the burden of the deodorant material 4 and prolongs the life of the activated carbon. In the deodorizing device according to claim 2 of the present invention, the sensor 10 attached to the toilet bowl B senses the human body sitting on the toilet bowl B,
Since the fan 2 operates weakly, the air in the toilet bowl B is not strongly sucked during the toilet and the person in the toilet does not get cold.
When a person leaves the toilet bowl B after use, the sensor-10
Detects that the person has moved away from the human body, the fan 2 operates strongly, so that the air in the toilet bowl B is strongly sucked and the deodorizing power is strengthened. The sensor 10 also detects a person who has approached the toilet bowl B for small use, and also detects that the person has left the toilet bowl B. In the deodorizing device according to claim 3 of the present invention, even when no person enters the toilet A for a long time, the fan 2 automatically operates by the action of the timer or the like after a predetermined time has passed from the previous operation, so that the inside of the toilet A is operated. Is automatically ventilated.

[0007]

EXAMPLE An example of the deodorizing apparatus of the present invention will be described with reference to FIG. Reference numeral 1 in FIG. 1 denotes an air intake portion for sucking air in the toilet bowl B, which is fixed to the toilet bowl B by a suction cup 11 or the like. The air intake part 1 is designed so that it can be attached to an existing toilet bowl B, but the newly created toilet bowl B has a tube insertion port 12 on the back surface of the toilet bowl B as shown in phantom in FIG.
Alternatively, the tube 7 may be directly attached to the insertion port 12. In this case, the end 13 of the tube 7
Will also serve as the intake section 1. Reference numeral 14 in FIG. 1 is a case to be placed in the toilet A, which is provided with an air tank 9, a fan 2, an ozone generator 3, and a deodorant 4 inside. The air tank 9 is a part from which the air sucked from the toilet B by the tube 7 is once discharged. By discharging the air here, the air can be efficiently sucked by the fan 2.
By the way, if the tube 7 is directly connected to the fan 2, the tube 7
Since the diameter of the fan is small, the suction efficiency of the fan 2 is poor. An ozone generator 3 primarily deodorizes the odor in the air sucked by the fan 2 by the action of ozone generated from the ozone generator. Ozone is an isotope of oxygen and is mainly used for the purpose of disinfection, deodorization, bleaching, etc., and it is known that it has a particularly strong deodorizing effect. As a result, the offensive odor components adsorbed on the deodorant material 4 such as activated carbon are reduced, so that the load on the deodorant material 4 is reduced and the life thereof is extended. Since the deodorizing effect of the activated carbon used for the deodorant material 4 decreases with the passage of time, it is necessary to replace the activated carbon used for a certain period. Therefore, the deodorant material 4 is placed near the discharge part 5 of the deodorizing device and is detachable so that it can be replaced.

In an embodiment of the deodorizing apparatus according to the second aspect of the present invention, reference numeral 10 in FIG. 1 is a sensor for detecting the approach and departure of the human body from the toilet bowl B. As the method, there are an infrared type that detects infrared rays generated by the human body, an ultrasonic type that constantly emits ultrasonic waves from the ultrasonic generator shown and detects reflected waves when hitting the human body, etc. is there. Further, it is necessary to consider the mounting position of the sensor 10 so that it is possible to detect the approach and departure of the human body even when the user does not sit on the toilet seat due to small use.

FIG. 2 is a flow chart showing the operation of the deodorizing apparatus according to claim 2 of the present invention. When the human body is detected by the sensor 10 of FIG. 1, the fan 2 of FIG. 1 operates weakly. In this case, it is desirable to operate the fan 2 after a lapse of about 15 seconds using a delay timer or the like in consideration of the time required for undressing. After that, when the person is away from the toilet bowl after use, the fan 10 is strongly operated by the sensor 10 to guide the odor of the stool or the smell of cigarettes to the tank 9. The operated fan 2 is automatically stopped by a timer after operating for a certain period of time. The strong operation of the fan 2 is not performed when the human body is removed, but the fan 2 may be strongly operated when the valve is operated in conjunction with, for example, a water washing valve.

The structure within the dotted line in FIG. 2 shows the operation of the deodorizing device of claim 3. Even if the sensor 10 does not detect the human body, the timer 2 causes the fan 2 to operate strongly for a fixed time (several minutes) at every arbitrary time.

[0011]

The deodorizing device in the toilet according to the present invention has the following effects. Since the odor is directly sucked from the toilet bowl B, it can be effectively deodorized in a short time. , No odor is emitted outside the toilet A, so there is no trouble in the neighborhood. Since ozone and activated carbon are used in combination, the life of the activated carbon used in the deodorant material 4 is extended, frequent replacement of the activated carbon is unnecessary, and the cost is not increased accordingly. , Can be installed without processing the toilet A. Since the device is small, it does not get in the way when it is placed in the toilet A.
