Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a deodorizing device used to remove unpleasant odors in toilets and other living spaces.

Conventional structure and problems Generally speaking, this type of deodorizing device is designed to improve the airtightness of residences, so that the living environment, especially the odor of toilets or, in flush toilets, the odor of excreted waste, can be a problem. It was first used to treat discomfort, and many are a combination of activated carbon and a fan. Currently, it is common to use fragrances to camouflage odors rather than to completely eliminate odors; however, sanitary cleaning equipment that has become increasingly popular in recent years includes products with built-in full-scale deodorization equipment. has been made into

Such a deodorizing device will be explained with reference to FIGS. 1 to 3.

Reference numeral 1 designates a toilet bowl, and a main body 2 of a sanitary cleaning device having a built-in deodorizing device and the like is combined with the rear upper part of the toilet bowl.

Reference numeral 3 denotes a water storage section that is provided at the rear of the toilet bowl 1 and stores water for washing away filth in the toilet bowl 1. Water for private washing is also introduced into the main body 2 via a water supply pipe 4.

Reference numeral 6 denotes a cleaning device section that includes a built-in hot water heating means for washing private parts, and 6 is a deodorizing device section.

7 is the toilet seat on which the user sits, and above it is the toilet bowl 1.
A toilet lid 8 for use when the toilet is not in use is placed thereon, and one end of both is supported by the device main body 2 so as to be openable and closable.

9 is a cleaning switch that adjusts the strength of cleaning water; 1
0 is a hot water temperature adjustment switch for cleaning, and 11 is a power switch.

Figure 2 shows the cross section A-B in Figure 1.
2 is a nozzle that spouts cleaning water controlled by the cleaning switch 9, and 13 is a hot air outlet for drying the private part after cleaning.

Reference numeral 14 is an opening/closing shaft for the toilet seat 7 and toilet lid 8, and a gravity switch 15 is provided at the bottom of the toilet seat 7, which is closed by the weight of the person sitting on the toilet seat 7. In addition, 16 is the main body 2 and the toilet bowl 1.
A fixing device consisting of bolts, nuts, etc. for fixing to the Reference numeral 17 is an inlet for the odor sent to the deodorizer 18 and fan motor 19, and reference numeral 20 is an outlet for discharging clean air after deodorization.

FIG. 3 is an electrical wiring diagram of the deodorizing device 6, in which a relay contact 21 which is closed by excitation of the relay coil 2Q is connected in series with the deodorizing motor 19.

Further, 13 is a gravity switch, and when a user sits on the toilet seat 7, the electronic circuit 22 operates to turn off the motor 1 for a certain period of time.
9 is operated and deodorization is performed.

Then, when the user leaves the toilet seat 7, the gravity switch 13
Even if the toilet is opened, the motor 19 continues to rotate for a certain period of time due to the action of the delay circuit 23, thereby completely eliminating the odor in the toilet.

However, such a deodorizing device 6 has the following problems.

■ The deodorizing device 6 can be used regardless of whether there is an odor or not, even when there is little odor, such as when a woman is washing her private parts or when doing errands.
Since the toilet is operated in a trench where you can stand up while sitting on the toilet seat, it is wasteful, and the operating noise of the deodorizing device 6 becomes a concern at night.

■ Also, since the system is operated for a certain period of time regardless of the strength of the odor, deodorization may not be sufficient when the odor is strong.

Purpose of the Invention The present invention focuses on the above-mentioned conventional problems, and provides a deodorizing device that automatically operates as soon as an odor occurs.
The purpose is to make it extremely easy to use.

A further object of the present invention is to provide a deodorizing device in which the operating time of the device is automatically adjusted depending on whether the odor is strong or weak by appropriately selecting the odor detection means.

Structure of the Invention In order to achieve the above object, the present invention comprises a deodorizing means made of a deodorizing agent or the like, a blowing means such as a blowing means for blowing air containing a bad odor to the deodorizing means, and an odor detection means,
The odor detection means is configured to energize the air blowing means.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

In FIG. 4, 24 is a main body placed above the rear part of the toilet bowl 25, and one end of the toilet seat 26 and the toilet lid 27 are attached to the main body 25.
It is supported so that it can be opened and closed freely.

28 is a leg provided at the bottom of the toilet seat 26.

29 is an odor sensor provided near the odor intake port 30, and 31 is an ejection port.

The suction port 30 and the discharge port 31 are fluidly connected through a wind tunnel 32, and inside there is a motor 33, a fan 34 driven by the motor 33, and a deodorizer 3 made of activated carbon.
5 is placed.

Generally, the main components that cause bad odors in defecation are hydrogen sulfide, ammonia, skatole, indole, etc., but there are many other components as well.

Next, referring to FIG. 5, the control system will be explained.

The connection point of the series circuit of the reference resistor 36 and the odor sensor 29 is connected to the relay coil 37 in series, and the control pole is connected to the rectifier element 3.
9 (hereinafter referred to as thyristor).

Further, the relay contact 38 of the relay coil 37 and the motor 33 that drives the deodorizing fan 34 are connected in series.

The odor sensor 29 circuit, the thyristor 39 circuit, and the motor 33 circuit are each connected in parallel to the power source.

As the odor sensor 29, a metal oxide, such as tin oxide or zinc oxide, which is used for detecting the leakage of toxic gases, is used.

The odor sensor 29 using such a metal oxide sensitively reacts to hydrogen sulfide, so it is suitable for detecting the foul odor of defecation.

By adsorbing hydrogen sulfide, the odor sensor 29 changes the height of the potential barrier that inhibits conductivity, and the conductivity, that is, the resistance, increases or decreases.

In the example, the resistance increases when hydrogen sulfide is adsorbed.

With this configuration, when the odor generated from defecation etc. reaches a level that is unpleasant to the human sense of smell, the resistance value of the odor sensor 29 exceeds the set value and the thyristor 39 is activated. Trigger.

Therefore, the relay coil 37 is energized by the current flowing between the anode and cathode of the thyristor 39, thereby closing the relay contact 38 and driving the motor 33.

When the deodorizing effect is achieved, the resistance value of the odor sensor 29 gradually decreases, the voltage applied to the gate of the thyristor 39 decreases, and eventually the anode and cathode of the thyristor 37 are opened, and the motor 33 starts operating automatically. It stops at .

Furthermore, if the odor is strong, the operating time of the motor 33 will inevitably become longer.

In this way, automatic operation of the deodorizing device becomes possible without any hassle.

In addition, in the detailed description of the present invention, the operating time of the motor 33 is also controlled depending on the strength of the odor, but
It is also possible to appropriately control the rotation speed, such as high speed when the odor is strong and low speed when the odor is weak.

Furthermore, it goes without saying that the deodorizing device is not limited to one that is placed on the toilet bowl as described in this explanation, and that various forms 2 such as floor-mounted type and wall-mounted type can be adopted within the same technical scope. . Furthermore, the application is not limited to toilets, but can be applied to remove all kinds of odors.

Effects of the Invention Since the deodorizing device of the present invention automatically controls the operation of the deodorizing means using the odor detection means, the deodorizing effect is high and the life of the deodorizing agent is extended.

In addition, the noise produced by the deodorizing means can be reduced, providing a good living environment for the residents.
