Abstract

PURPOSE:To provide a deodorizer whose operating time, after a user has leaved a lavatory, is controlled in accordance with how long the user is in the lavatory. CONSTITUTION:Signals of a human body sensor 2 are subjected to computations at a processing portion 3 and then a motor 5 is turned on or off through a control portion 4; an excellent deodorizer with no wasteful power consumption is thus obtained which is operated for a proper period such that after a user has leaved a lavatory the operating time is controlled in accordance with how long the user is in the lavatory.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to operation control of a deodorizer.

[0002]

2. Description of the Related Art A conventional deodorizer equipped with a human body detection sensor is generally configured to start operation when a person enters the toilet and stop after a certain period of time when the person leaves the toilet. It was

[0003]

However, in the above-mentioned conventional configuration, the deodorizer operates for a certain period of time after use regardless of the length of time that a person is in the toilet, so that the odor is completely removed. The operation will stop before it's complete,
There was a problem that the operation was not continued even though the odor had already disappeared, and it did not match the actual situation, and wasted power consumption.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a deodorizer capable of performing an appropriate operating time.

[0005]

To achieve this object, the deodorizer of the present invention has, in the first means, a structure for controlling the operating time after use by the length of the signal input from the human body detection sensor. is doing.

Further, the second means has a structure in which the driving time after use can be determined more reliably by the signals of the human body detection sensor and the gas sensor.

[0007]

With this configuration, in the first means, the human body detection sensor is used to detect the length of time the person enters the toilet.
The operation time of the deodorizer after leaving the room is controlled.

In the second means, the size of the odor inside the room can be detected by the gas sensor, and the operating time after leaving the room can be further controlled by the human body detection sensor.

[0009]

【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, 1 is a rectifying power source section, 2 is a human body detection sensor for detecting a change in far infrared rays emitted by a human body, and outputs a signal, and 3 is a microprocessor for processing the signal of the human body detection sensor 2. The processing units 4 and 4 are motor control units that perform on / off control of the motor 5 that drives the deodorizer.

Regarding the deodorizer configured as described above,
The operation will be described with reference to FIG. First, when a person enters the toilet, an output is output to the human body detection sensor 2 and the deodorizer starts operating. Since the human body is constantly detected while a person is in the room, the deodorizer operates for the time to enter the room. Next, after the person leaves the room, no signal output from the human body detection sensor 2,
The processing unit 3 lengthens the operation time ti after leaving the room when the deodorizer operation time to is long, and shortens the operation time ti after leaving the room when the operation time to is short.

As described above, according to the present embodiment, the deodorizer can be operated after leaving the room in accordance with the time when a person has been in the toilet, so proper deodorization and unnecessary power consumption are eliminated. be able to.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to the drawings. The same components as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 2, 6 is a gas sensor for detecting a change in odor in the toilet and outputting a signal, which signal is input to the processing unit 3.

With respect to the deodorizer constructed as described above,
The operation will be described. First, as described in the first embodiment, the deodorizer is operated for ti time after a person leaves the toilet by the human body detection sensor 2. A signal is sent to the processing unit 3 to further lengthen or shorten the time ti.

As described above, according to the present embodiment, the deodorizer can be finely operated after leaving the toilet according to the amount of odor in the toilet, and wasteful power consumption can be eliminated.

[0017]

As is apparent from the above description of the embodiments, the first means is suitable because the operating time of the deodorizer after leaving the room is controlled according to the time the person is in the toilet. It is possible to set unnecessary operating time and eliminate unnecessary power consumption.

In the second means, the gas sensor detects the magnitude of the odor in the room, and the operating time after leaving the room by the first means is further lengthened or shortened.
It is possible to realize an excellent deodorizer that can eliminate wasteful power consumption as well as fine-tuned operation.
