Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device for deodorizing water. More specifically, the present invention relates to a deodorizing device that reduces the maintenance cost by passing the air sucked from the outside through the holes of the porous body in which water is sprinkled to perform deodorization.

[0002]

2. Description of the Related Art In a conventional deodorizing device, for example, a toilet deodorizing device, a chemical deodorizing method using zeolite or the like, an adsorption method using activated carbon that has been chemically treated, a catalytic oxidation method using a catalyst, an ozone oxidizing method using ozone, and an aromatic agent are used. Deodorization and deodorization were performed using a masking method or the like.

[0003]

However, in a deodorizing device for a toilet using a chemical deodorizing method or an adsorption method using activated carbon or the like, it is necessary to replace the filter about every 6 months, which is not only a troublesome replacement work. There was a problem that maintenance costs were required. In addition, used filters may require special disposal, which is environmentally problematic.

In a deodorizing device for a toilet using the catalytic oxidation method, if dust or the like adheres to the surface of the catalyst, the deodorizing efficiency may be extremely reduced, and the deodorizing action may not be sufficiently performed. Also, the catalyst with dust etc. cannot be washed at home, so the catalyst itself must be replaced.
There was a problem that maintenance costs were required. Further, the toilet deodorizing device using the ozone oxidation method has a problem that the ozone generating device is expensive.

Further, in the conventional toilet deodorizing device, the deodorizing efficiency is lowered due to the above-mentioned causes, and when the bad odor is not completely removed and the air is discharged, the odor is rather scattered into the toilet room. There was a problem.

Therefore, the present invention solves the above-mentioned problems, and proposes a deodorizing device which is inexpensive, can reduce the maintenance cost, and is environmentally advantageous.

[0007]

In order to solve the above problems, in the present invention, in a deodorizing device for deodorizing and sucking out air sucked from the outside, air is introduced into a porous body and pores of the porous body. A fan for passing through, a driving means for rotating the fan, and a sprinkling means for sprinkling water on the porous body are provided, and the air sucked from the outside is passed through the holes of the porous body on which the water is sprinkled. It is characterized by deodorizing by doing so.

Further, a mesh portion 38, which is a thin plate-like porous body having a large number of small holes, is provided on the outer surface of the sirocco fan 32 so as to cover the entire circumference. A material such as a cloth filter, a wire mesh, or a sponge is selected for the mesh portion 38.

As shown in FIG. 1, an exhaust pipe 39 for discharging deodorized air is connected to the fan casing 30, and the exhaust pipe 39 discharges the deodorized air from the upper part of the cabinet 12. ing. A bottom portion of the fan casing 30 is formed in a funnel shape, and a pump portion 40 is arranged below the funnel shape. This pump part 4
0 is for discharging the water used for deodorization to the outside.

In the pump section 40, the pump casing 4
3, a disk-shaped centrifugal pump 41 is arranged inside, and this centrifugal pump 41 is connected to a rotary shaft 34 of a motor 33 and is rotationally driven together with a sirocco fan 32 and a sprinkler plate 37. As shown in FIGS. 4 and 5, the centrifugal pump 41 is provided with a circular groove portion 55 around the rotary shaft 34, and the plurality of drain holes 5 communicating from the groove portion 55 to the side surface of the centrifugal pump 41.
6 are provided. The drain holes 56 are each formed in a curved shape, and are provided at equal intervals, for example, every 45 degrees over the entire circumference of the centrifugal pump 41. A drain pipe 42 is connected to a side surface of the pump casing 43, and the drain pipe 42 is arranged inside the intake pipe 14 as shown in FIG. 1 so as to discharge water into the toilet 11.

A substrate 46 is arranged below the motor 33, and electronic components for controlling various operations are mounted on the substrate 46. Further, a sensor 47 such as an infrared sensor or a temperature sensor is attached to the board 46 so as to detect that the user approaches the toilet 11.

The operation of the toilet deodorizing device 1 configured as described above will be described below. Now
When the user approaches the toilet bowl, the sensor 47 senses this and turns on the motor 33 and the solenoid valve 24. As a result, the motor 33 is rotated to rotationally drive the sirocco fan 32, the water spray plate 37, and the centrifugal pump 41, the valve 24a of the electromagnetic valve 24 is opened, and the supply of water from the opening 23 of the tank 21 is started. . At this time, the amount of water flowing out from the tank 21 is set to, for example, about 2 to 4 cc per second.

The sirocco fan 32 shown in FIG. 3 rotates counterclockwise, and each impeller 36 generates a suction force from the inside to the outside. As shown by the solid line arrow in FIG.
The water flowing out from No. 3 is a sprinkling plate 37 that rotates beneath it.

The water that has dropped onto the upper surface of the water spray plate 37 is scattered outward by the centrifugal force that accompanies the rotation of the water spray plate 37 and the suction force of the sirocco fan 32. The water droplets pass between the impellers 36 and collide with the mesh portion 38, whereby the mesh portion 38 is covered with the water film.

Air is sucked through the intake pipe 14 (FIG. 1) and the vertical portion 28 by the suction force of the sirocco fan 32. Then, the sirocco fan 32 is fed into the sirocco fan 32 as shown by a dotted arrow, passes between the impellers 36, and through the small holes of the mesh portion 38.
Is discharged to the outside. At this time, since the air passes through the small holes of the mesh portion 38 while being mixed with the water, most of the odorous components contained in the air are absorbed by the water and deodorized. The water that has absorbed the odor component also passes through the small holes of the mesh portion 38 and is discharged to the outside of the sirocco fan 32.

The deodorized air rises through the exhaust pipe 39 and is discharged to the outside. Further, the water that has absorbed the odor component is collected by the funnel-shaped inclined surface of the bottom of the fan casing 30, and flows into the groove 55 (FIG. 4) of the centrifugally driven centrifugal pump 41 shown in FIG. The water flowing into the drain holes 56 is discharged from the plurality of drain holes 56 by the centrifugal force of the centrifugal pump 41, and is forcibly sent to the drain pipe 42. Then, this water passes through the drain pipe 42,
It is discharged into the toilet bowl 11 shown in FIG.

When the user leaves the toilet bowl 11,
The sensor 47 detects this and the motor 33 and the solenoid valve 2
Turn off 4 after a predetermined time. As a result, the rotation of the sirocco fan 32, the water spray plate 37, and the centrifugal pump 41 is stopped, the valve 24a closes the opening 23, and the deodorizing operation ends. In this example, the power is automatically turned off 20 minutes after the deodorizing operation is started.

As described above, according to the present invention, water is used for deodorization, so that it is not necessary to replace the filter or the catalyst as in the conventional toilet deodorizing device, and the maintenance cost can be reduced. Further, the bad odor peculiar to the toilet such as ammonia is hydrophilic, and the deodorizing effect can be enhanced by using water. Since the water used for deodorization is flushed by the toilet 11, there is no problem of disposal of the filter and it is environmentally superior. Furthermore, sirocco fan 32, sprinkler plate 37
Since the centrifugal pump 41 and the centrifugal pump 41 are driven by the single motor 33, the structure can be simplified and the cost can be reduced.

FIG. 7 shows the structure of a toilet deodorizing device 50 according to a second embodiment of the present invention. The basic operation of the deodorizing device 50 for toilet is the same as that of the deodorizing device 1 for toilet according to the first embodiment. The exhaust pipe 51 in this example is bent horizontally in the middle, penetrates the cabinet 12, and projects to the outside. Then, as shown in FIG. 8, the exhaust pipe 5
1 goes around the side of the toilet bowl 11 on the opposite side of the toilet bowl 11 and discharges air into the toilet bowl 11 by means of an exhaust pipe attachment portion 53 hooked on the edge of the toilet bowl 11.

When this toilet deodorizing device 50 is operated, a flow of air is formed from the exhaust pipe mounting portion 53 side to the intake pipe 14 side, and deodorizing is performed while circulating air containing odors, so deodorizing efficiency is improved. Can be further increased. Further, even if the air is discharged without completely removing the malodor, the air containing the odor is circulated only between the toilet deodorizing device 50 and the toilet 11, so that the diffusion of the odor is prevented. be able to.
