Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a toilet deodorizing device.

0002

[Conventional technology]

Traditionally, toilet deodorizing devices have been installed in air suction pipes equipped with fans, for example. Products that suck out the foul-smelling gas in the toilet bowl and pass this odor into deodorizers or air fresheners, A device that discharges and dissolves foul-smelling gas directly into the water in the wash water tank (Japanese Patent Application Laid-open No. 1983- 62531) is known.

0003

[Problem that the idea aims to solve]

However, in the former deodorizing device, in order to maintain the deodorizing ability, deodorizing agent or It is necessary to replace (replenish) the air freshener regularly, and maintenance work is troublesome. It was.

0004 In addition, in the latter case, there is a limit to the amount of foul-smelling gas that can dissolve in water. The drawback was that unbearable foul-smelling gas wafted into the toilet room.

[0005] The present invention was developed in view of the above-mentioned drawbacks of the conventional technology, and it reduces maintenance work. The purpose is to provide a deodorizing device that is not troublesome and has good deodorizing efficiency.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the deodorizing device of the present invention has a porous structure with microorganisms attached to it. It has a deodorizing room where materials are stored, a water supply channel and a drainage channel are connected, and an opening inside the toilet bowl. One end is connected to the deodorizing chamber, and the other end is connected to the deodorizing chamber, and the air deodorized in the deodorizing chamber is discharged. and an on-off valve installed in each of the water supply channel and the drainage channel. , the configuration includes a controller that opens and closes the on-off valve at regular intervals. There is.

[0007]

[Effect]

With the above configuration, this invention sends the foul-smelling gas sucked from inside the toilet bowl into the deodorizing room. , the malodorous components are dissolved in water and adsorbed by microorganisms. promotes dissolution in water and improves deodorizing efficiency.

[0008] Microorganisms proliferate by adsorbing malodorous components, but it is important to open and close the valve at regular intervals. It opens and closes to drain water containing microorganisms from the drainage channel and supply fresh water from the water supply channel. This prevents the death of microorganisms due to proliferation (exceeding the allowable amount) and reduces maintenance costs. Eliminate the hassle of work.

【Example】

FIG. 1 shows an embodiment of the present invention, in which 1 is a toilet bowl, 4 is a flush water tank, and 25 is a toilet bowl 1. This is a deodorizer mounted on the rear of the car. Toilet bowl 1 and flush water tank 4 are toilet bowl flush water pipe 8 After using the toilet, the flushing water in the flushing water tank 4 is flushed into the toilet flushing water pipe 8, and the toilet is flushed with water. The container 1 can be washed.

0010 3 is an air suction pipe having an opening 2 (hereinafter referred to as air suction port 2) inside the toilet bowl 1; The air suction pipe 3 is introduced into the deodorizer 25.

[0011] In the deodorizer 25, an air pump 10 is installed in the air suction pipe 3, and the air pump 10 is connected to the air suction pipe 3. One end of the suction pipe 3 is connected to the deodorizing chamber 11.

0012 A backflow prevention plate 6 made of a selectively permeable material is provided at the bottom of the deodorizing chamber 11. The air sent from the air pump 10 is passed through, and the water in the deodorizing chamber 11 is This prevents the air from flowing back into the air pump 10. Instead of backflow prevention plate 6, air pocket A check valve may be provided in the air suction pipe 3 downstream of the pump 10.

[0013] Next, microorganisms such as bacteria were attached to the backflow prevention plate 6 in the deodorizing chamber 11. A porous material 5 (for example, made of ceramics) is provided and immersed in water. .

[0014] 12 is an exhaust pipe connected to the upper part of the deodorizing chamber 11, with an exhaust port 23 opening at the end. The deodorized air inside the deodorizing chamber 11 is discharged outside the chamber.

[0015] Reference numeral 13 denotes a drain opening at the bottom of the deodorizing chamber 11, and an on-off valve 15 consisting of a solenoid valve. An interposed drain pipe 14 is connected and communicates with the toilet flush water pipe 8.

[0016] 16 is a water supply channel, and the first water supply channel 1 is located downstream of the governor 18 that limits the water supply flow rate. 6a and a second water supply channel 16b. The first water supply channel 16a is the deodorizing chamber 11 It is connected to the upper part of the deodorizing room 11.

[0017] The second water supply channel 16b is for supplying city water to the cleaning nozzle 21 and is open. A closing valve 19 and a hot water tank 20 equipped with a heater are provided.

[0018] The above deodorizing device is equipped with a central processing unit (CPU) in a controller (not shown), and The closing valves 15 and 17 are opened and closed at regular intervals to drain water containing microorganisms inside the deodorizing chamber 11. It is designed to discharge a predetermined amount of water and supply a predetermined amount of new water.

[0019] Next, the operation of the above configuration will be explained. After using the toilet, turn the deodorizing switch (not shown) to O. When set to N, the air pump 10 is activated and the air containing bad odor inside the toilet bowl 1 is sucked out. Air is sucked into the suction pipe 3 from the opening 2, passes through the backflow prevention plate 6 at the bottom of the deodorizing chamber 11, and is extinguished. It is brought into contact with the water inside the odor chamber.

[0020] The malodorous components in the malodorous gas dissolve in water and are immediately absorbed by microorganisms attached to the porous material 5. It gets absorbed. Therefore, the concentration of malodorous components in water becomes close to 0, and the concentration of malodorous components in water becomes The dissolution into is promoted, and the deodorizing efficiency is increased.

[0021] The malodorous components are used as an energy source by microorganisms, and the microorganisms multiply, but If the microorganisms grow beyond the allowable amount, all the microorganisms will die.

[0022] However, a controller (not shown) causes the on-off valve 15 to open for a predetermined period of time. Then, a predetermined amount of water containing the grown microorganisms is discharged from the drain 14 into the toilet bowl 1. Then, the on-off valve 17 is opened for a predetermined period of time to deodorize a predetermined amount of fresh water from the first water supply channel 16a. Since it is supplied indoors, the amount of microorganisms in the deodorizing room 11 is kept constant and death is prevented. Ru. Therefore, there is no need for maintenance work.

[0023] The above-mentioned fixed period refers to the rate of growth per unit time due to the adsorption of malodorous components by microorganisms. and the permissible amount of microorganisms in the deodorizing room 11, and as appropriate for 24 hours. Or, decide on a period such as one week.

[0024]

[Effect of the idea]

As is clear from the above examples, the deodorizing device of the present invention is capable of eliminating malodorous components in malodorous gas. It is dissolved in the water in the deodorizing room and adsorbed to microorganisms, making it very effective in deodorizing. Becomes good. In addition, water containing proliferated microorganisms is drained from the drain at regular intervals. Since fresh water is supplied into the deodorizing room, the amount of microorganisms in the deodorizing room is kept constant and maintenance is maintained. This eliminates the hassle of maintenance work, etc.
