[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device and a garbage disposal device equipped with the deodorizing device.

[0002]

2. Description of the Related Art Conventionally, as a raw garbage processing apparatus, a raw garbage processing section for fermenting and aging the raw garbage inside a casing, and a final residue after the fermentation and aging processing by the raw garbage processing section Some have provided a recovery unit for recovering an object and a deodorizing unit for deodorizing the odor generated from the garbage treated by the garbage treating unit.

The deodorizing unit is provided with a deodorizing device, and the deodorizing device has a deodorizing case in which a deodorizing filter is housed and disposed in the deodorizing flow passage, and the malodorous components flowing into the deodorizing case are supplied to the deodorizing filter. It is configured to be adsorbed and deodorized, and the deodorized treated air is discharged to the outside through an exhaust mechanism.

A deodorizing catalyst such as a photocatalyst is used in the deodorizing filter. In the case of such a photocatalyst, the odorous component adsorbed on the filter can be decomposed by activating it by irradiating it with ultraviolet rays. When was used up to near saturation, the filter was regenerated by irradiating light from an ultraviolet lamp.

[0005]

However, in the above-mentioned conventional deodorizing apparatus, it takes a lot of time to regenerate the filter, and it is a problem to shorten the regenerating time.

[0006] For example, in a deodorizing filter carrying a photocatalyst, even if it is irradiated with ultraviolet rays for regeneration, it is difficult for the malodorous components to decompose at a distance from the ultraviolet lamp.
This is because a concentration gradient is created between the portion near the surface of the ultraviolet lamp and the portion far from the surface.

Therefore, if the malodorous component does not move to the vicinity of the surface of the ultraviolet lamp, the decomposition will not proceed and eventually it will take time.

Therefore, in the conventional garbage processing apparatus equipped with such a deodorizing device, there may be a case where a bad odor is generated between filter regeneration, and in order to avoid it, the garbage is kept until the filter is regenerated. I had to refrain from processing.

An object of the present invention is to provide a deodorizing device that can solve the above-mentioned problems, and a garbage disposal device equipped with the deodorizing device.

[0010]

In order to solve the above-mentioned problems, the present invention according to claim 1 provides a deodorizing case in which a deodorizing filter is housed in the deodorizing flow path, and the malodor that has flowed into the deodorizing case is provided. In the deodorizing device capable of deodorizing the components by adsorbing the components to the deodorizing filter and decomposing the malodorous components adsorbed on the deodorizing filter, the deodorizing filter can be regenerated. To circulate.

According to the second aspect of the present invention, a fan is provided in the deodorizing passage, and the downstream side and the upstream side of the deodorizing case are connected by a bypass passage so as to include the deodorizing case. A circulation channel is formed, and air is circulated in the circulation channel when the deodorizing filter is regenerated.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is provided with a deodorizing case in which a deodorizing filter is housed in a deodorizing flow passage, and a malodorous component flowing into the deodorizing case is adsorbed by the deodorizing filter to enable deodorization. In a deodorizing device capable of regenerating a deodorizing filter by decomposing a malodorous component adsorbed on the deodorizing filter, air is circulated in the deodorizing case when the deodorizing filter is regenerated.

That is, when the filter is regenerated, the malodorous component can be positively removed from the filter by circulating the air in the deodorizing case, and the malodorous component can be easily decomposed, so that the filter regeneration time can be shortened. . Therefore, it is possible to provide a deodorizing device which has good maintainability and which can be continuously used and is easy to use.

In order to circulate the air in the deodorizing case, for example, a fan is arranged in the deodorizing case, and the downstream side and the upstream side of the deodorizing case are connected by a bypass passage to connect the deodorizing case. It is advisable to form a circulation flow path including the above and to circulate air through the circulation flow path when the deodorizing filter is regenerated. The fan may be installed in the deodorizing case.

With this structure, air can be smoothly circulated in the deodorizing case.
Air can be circulated and flowed into the deodorizing filter many times to promote the removal of the malodorous components.

Further, it is desirable to provide a flow path switching valve at each of the start end and the end of the bypass flow path.

That is, by switching the flow path by the flow path switching valve, it is possible to easily switch between the flow path during the normal deodorizing process and the flow path during filter regeneration, and the filter regeneration time is short, so the deodorizing device can be used. It is easy to use.

By the way, it is preferable that the deodorizing filter has a photocatalyst as a deodorizing catalyst and is provided with an ultraviolet lamp for irradiating the photocatalyst with ultraviolet rays.

That is, it is known that the photocatalyst effectively decomposes the malodorous component by irradiating it with ultraviolet rays. In combination with the above-mentioned structure, the malodorous component can be efficiently decomposed in a short time. Therefore, the filter regeneration time can be significantly shortened.

Further, the deodorizing flow path may be branched from the middle and a deodorizing case may be provided in each of the two branch flow paths.

According to this structure, the deodorization process can be performed efficiently by using the two deodorization flow paths, and the deodorization process can be performed while the filter is regenerated in one deodorization flow path. , There is no need to stop the deodorizing process for filter regeneration.

The deodorizing device described above can be suitably used for a raw garbage treating apparatus provided with a raw garbage treating tank for fermenting and aging raw garbage.

In other words, in the deodorizing device having the above-mentioned structure, effective deodorization can be performed by introducing the odor generated in the garbage processing tank into the deodorizing channel, and the deodorizing filter can be regenerated for a short time. Therefore, the usability is significantly improved for both home and business use.

As described above, the garbage disposal provided with the deodorizing device according to the present embodiment can prevent the generation of a bad odor and provide a comfortable garbage disposal. Even if the deodorizing filter is operated for a long time and the deodorizing filter is saturated, the filter can be quickly regenerated, so that the garbage processing is not delayed in order to prevent the generation of a bad odor.

[0029]

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a schematic explanatory view of the deodorizing apparatus A according to the present invention.

As shown in the figure, the deodorizing device A is constructed by providing a transparent cylindrical deodorizing case C in which a deodorizing filter F is housed and disposed in a deodorizing flow path R whose start end faces an unillustrated malodor generating source. It was done.

The deodorizing flow path R in this embodiment is the first branch flow path R1 from the middle through the first three-way valve V1 which is a flow path switching valve.
And the second branch flow path R2.
A deodorizing case C is provided for each of R1 and R2. The two exhaust passages R1 'and R2' extending from the end portions of both deodorizing cases C join and communicate with an exhaust duct 71 (see FIG. 4) described later. That is, the deodorizing flow path R in this embodiment includes the first and second branch flow paths R1 and R2, the inside of the deodorizing case C, and the exhaust flow path R.
It will consist of 1 ', R2'.

Further, the upstream side of the deodorizing case C of the first and second branch flow paths R1 and R2 and the middle of the exhaust flow paths R1 'and R2' are connected by bypass flow paths R3 and R4, respectively. do it,
The circulation channel S including the deodorizing case C is formed (indicated by an arrow in the figure).

Further, second-fifth three-way valves V2-V5 having the same structure as the above-mentioned flow path switching valve are also provided at the connecting portions between the bypass flow paths R3, R4 and the deodorizing flow path R. In addition, these 5
Each of the three three-way valves V1 to V5 can be opened / closed by a signal output from a control unit (not shown) as needed.

Inside the deodorizing case C, a suction fan 68 for sucking and discharging odors and a deodorizing filter F carrying a deodorizing catalyst are housed.

In this embodiment, the suction fan 68 is arranged at the end of the deodorizing case C, and the deodorizing filter F is arranged in the middle of the case.
As long as it is disposed inside and the malodor can be sucked and introduced into the deodorization flow path R, the location of the disposition is not limited at all.

With such a configuration, the bad odor sucked and introduced into the deodorizing flow path R is determined by the first three-way valve V1 depending on the load of the processing work.
The flow path is switched by, and the deodorizing process is performed by causing the deodorizing filter F to adsorb the malodorous component contained in the first and second branching channels R1, R2 or both,
It is discharged from the exhaust flow paths R1 'and R2' in a purified state.

Further, in the deodorizing case C, a pair of ring-shaped fluorescent lamps, that is, fluorescent tubes 80 are disposed so as to sandwich the deodorizing filter F, and ultraviolet rays can be irradiated toward the deodorizing filter F.

That is, in this embodiment, a photocatalyst is used as a deodorizing catalyst. Titanium oxide that acts as a photocatalyst is applied to, for example, glass fibers, and the glass fibers are formed into a net shape. Deodorizing filter F
Are configured.

As described above, the deodorizing apparatus A uses the photocatalyst as the deodorizing catalyst and is equipped with the fluorescent tube 80 capable of irradiating ultraviolet rays. Therefore, the malodorous components adsorbed on the deodorizing filter F are converted into ultraviolet rays. Is irradiated and decomposed, and the deodorizing filter F is repeatedly regenerated so that the deodorizing process can always be performed in an optimum state.

In the above structure, the characteristic feature is that
The air is circulated in the deodorizing case C when the deodorizing filter F is regenerated.

That is, when the deodorizing filter F is regenerated, by circulating air in the deodorizing case C, the malodorous components can be positively removed from the deodorizing filter F, and the malodorous components can be easily decomposed. It is possible to significantly reduce the reproduction time of F.

For example, the odor is sucked and introduced into the first branch flow path R1 to continuously perform the deodorizing process, and the first branch flow path R1
When the deodorizing filter F disposed in the deodorizing case C becomes almost saturated, in this embodiment, the filter regeneration process can be performed as follows.

First, the fluorescent tube 80 is turned on to irradiate the deodorizing filter F with ultraviolet rays, and the first three-way valve V1
The port is switched so that the odor flows to the second branch flow path R2. As a matter of course, in the second branch flow path R2, the deodorizing process can be performed as usual.

On the other hand, in the first branch flow path R1 whose flow path is blocked by the first three-way valve V1, the ports of the second and third three-way valves V2 and V3 are switched and the suction fan 68 is driven, The air in the flow path is circulated in the circulation flow path S including the deodorizing case C.

Therefore, the air smoothly circulates in the deodorizing case C, and when the air flow passes through the deodorizing filter F, the malodorous components can be removed and the deodorizing filter F can easily move.

On the other hand, by irradiation of ultraviolet rays from the fluorescent tube 80,
The malodorous components in the vicinity of the surface of the deodorizing filter F are close to the surface of the fluorescent tube 80 and are directly affected by ultraviolet rays, so that the malodorous components are effectively decomposed by the action of the photocatalyst. Therefore, in the deodorizing filter F, a concentration gradient is generated between a portion close to the fluorescent tube 80 and a portion far from the fluorescent tube 80, but the malodorous component in the portion far from the fluorescent tube 80 is effective due to the air circulation flow path as described above. Since it has been dropped to the fluorescent tube 80, it is rapidly moved to a portion close to the fluorescent tube 80, and after moving, it is efficiently decomposed by the photocatalyst activated by ultraviolet irradiation. By repeating these actions, the deodorizing filter F is quickly regenerated, and the deodorizing process can be performed again in the first branch flow path R1.

Moreover, for the deodorizing process, the second branch flow path is used.
Since it is continuously performed in R2, it does not interfere with the deodorizing process.

As described above, according to the present embodiment, the flow passage switching valve (three-way valve V1 to V5) is used to switch the flow passages so that the flow passage during the normal deodorizing process and the flow passage during the filter regeneration are separated. Since it can be easily switched and the filter regeneration time is short, it is extremely convenient as a deodorizing device.

In this embodiment, the deodorizing filter F is described as a mesh type, but the filter shape is not limited at all. For example, a large number of granular, spherical, or polygonal structures made of glass or ceramic supporting a photocatalyst such as titanium oxide may be assembled, or titanium oxide or the like may be supported on a porous carrier. It may be of a different type, or another form may be adopted.

By the way, the deodorizing apparatus A described above can be suitably adopted for the raw garbage treating apparatus 1 provided with the raw garbage treating tank 33 for fermenting and aging the raw garbage.

That is, the deodorizing device A having the above structure
In this case, by introducing the odor generated in the garbage processing tank 33 into the deodorization flow path R, effective deodorization can be performed, and moreover, the regeneration of the deodorization filter F can be completed in a short time.
It is possible to configure the garbage processing device 1 that is easy to use regardless of whether it is for business use. Although the deodorizing device A is schematically described in FIG. 1, its form can be modified and applied in any way, and any form of the garbage processing device 1 can be appropriately incorporated. . For example, deodorizing device A
Can be housed in the exhaust duct 71 included in the general garbage processing device 1, or the suction fan 68 can be provided outside the deodorizing case C.

As described above, the deodorizing apparatus A according to the present embodiment can be suitably incorporated in the garbage processing apparatus 1, and the garbage processing apparatus 1 equipped with such a deodorizing apparatus A does not generate a bad odor. Along with preventing and comfortable garbage disposal,
For example, since the garbage processing device 1 is continuously operated to deodorize for a long time, and the filter can be promptly regenerated even when the deodorizing filter becomes saturated, the garbage processing is stagnant in order to prevent the generation of a bad odor. There is nothing to do.
