Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a compost obtained by subjecting garbage discharged from a home kitchen or the like to a fermentation decomposition treatment.
The present invention relates to an exhaust mechanism of a garbage disposal device.

[0002]

2. Description of the Related Art Conventional garbage fermentation / decomposition technology for household use is known in the art, and garbage and fermentation bacteria are put into a container and stirred to promote fermentation and remove water.
The waste was reduced and composted while undergoing fermentation and decomposition treatment. Raw garbage was further added thereto, and the mixture was repeatedly stirred and fermented, collected as compost, and used as fertilizer for home gardens and the like. The air containing the odor generated by the fermentation decomposition treatment is discharged directly from the fermenter for performing the fermentation decomposition treatment to the outside of the processing machine main body through an exhaust duct, or is discharged to the outside through a deodorizing device attached to the processing machine. Or it was either.

[0003]

In the former method, air containing odor is directly discharged to the outside.
There was an adverse effect such as the odor trapping near the processing machine. In the latter case, it is necessary to separately provide a special device such as a deodorizing device, which increases the cost of the processing machine itself. Further, a mechanism for discharging air containing odor leaked into the interior between the processing container and the casing is not provided in the processing machine itself, and may cause dew condensation inside the casing or even if the inside is cleaned. Odor sometimes remained. In other words, there has been a demand for a garbage disposer that reduces the odor concentration of the discharged air without providing a special deodorizing device and that also takes into consideration the ventilation of the inside of the body between the casing and the container of the disposer.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. In claim 1, a garbage disposal machine equipped with a fermenter for fermenting garbage,
An exhaust fan was provided to simultaneously inhale and exhaust air inside the fermenter and air outside the fermenter.

According to a second aspect of the present invention, the exhaust fan is used as a sirocco fan to suck air in the fermentation tank from one intake port and air between the fermenter tank and the casing from the other intake port. Both were mixed and discharged from the exhaust port.

According to a third aspect of the present invention, a shutter is disposed at the intake port so that the mixing ratio can be changed.

The upper part of the fermenter 1 is opened and an inlet 1 is provided.
The garbage input port 10a formed in the upper part of the casing 10 is inserted into the input port 1e. The raw garbage input port 10a is closed by the input lid 12 so that the fermenter 1 can be hermetically closed, heat in the fermenter 1 is not escaped, and an environment suitable for fermentation is maintained. I try not to.

Next, the exhaust mechanism of the present invention will be described. In the fermenter 1, suction ports 1h and 1h capable of inhaling outside air are opened at an upper portion of one side surface, and the suction ports 1h and 1h are opened.
The exhaust port 1a is provided on the side opposite to the side h.
Is connected to The exhaust part 20 is composed of an exhaust fan 21 and an exhaust duct 22. The exhaust fan 21 as an exhaust means is screwed and fixed to an outer surface of the exhaust port 1 a of the fermenter 1, and exhaust is performed to a discharge port 21 d of the exhaust fan 21. Duct 22
The exhaust duct 22 is made of rubber, synthetic resin, or the like. The lower end of the exhaust duct 22 is fitted into a silencing chamber 24 provided to reduce exhaust noise,
4 is fitted to an exhaust port 83 provided in a rear wall 10e of the casing 10.

As shown in FIGS. 5 and 6, the exhaust fan 21 is constituted by a sirocco fan that can be sucked from both left and right sides, and not only the air inside the fermenter 1 through the exhaust port 1a but also the fermenter. The air inside the garbage disposal machine 9 outside the tank 1 is also sucked. 6 indicates the flow of air from the fermenter 1, and the solid arrow B indicates the air flow from the fermenter 1.
It shows the flow of air from the outside.

Therefore, when the exhaust fan 21 is driven, the inside of the fermenter 1 is drawn through the inlets 1h and 1h inside the fermenter 1.
The outside air is sucked into the inside, and air (oxygen) is spread on the upper surface of the processed material stirred by the stirring claws 18, 18..., And the gas generated during fermentation and the moisture in the processed material flow through the air. Fan 2 through the exhaust port 1a
It is sucked into 1. As shown in FIG. 4, outside air is sucked from the casing outside the fermenter 1 through a suction port 1 m at the bottom of the garbage disposal machine 9, and is similarly sucked by the exhaust fan 21. Air sucked from inside and outside the fermenter 1 is mixed, air containing odor from the inside of the fermenter 1 is diluted, and exhausted to the outside of the garbage disposal machine 9 from an exhaust port 83 below the exhaust part 20. .

As shown in FIGS. 7 and 8, the exhaust fan 21 is provided with intake ports 21a, 21a... For sucking air outside the fermenter 1 on the left side, and the fermenter on the right side. 1 Intake ports 21b, 21b,.
Is provided. With the above configuration, the exhaust fan 21
The air inside and outside the fermenter 1 is sucked. A shutter 2 for adjusting the intake air amount is provided on the right side of the exhaust fan 21.
1c, the area of the opening of the air inlet 21b can be changed by sliding the shutter 21c, and the flow rate of air from inside the fermenter 1 is adjusted. By this operation, the air intake ratio of the inside and outside air of the fermenter 1 by the exhaust fan 21 is adjusted, and the inside and outside air mixing ratio for odor dilution can be appropriately given. Further, it is also possible to arrange a shutter at the intake port 21a to adjust the intake amount. The air thus mixed is discharged to the exhaust duct 22 through the discharge port 21d as shown in FIG.

[0020]

As described above, the present invention has the following advantages. That is, as in claim 1, a garbage disposal machine equipped with a fermenter for fermenting garbage, wherein the air inside the fermenter and the air outside the fermenter are simultaneously sucked and exhausted. Since the fan is provided, the air inside and outside the fermenter is mixed to dilute the air containing the former odor, and the odor concentration discharged from the exhaust port is reduced. In addition, since the air inside the garbage disposer is also ventilated, it is possible to prevent the odor from remaining inside and prevent the odor-containing air from drying and forming dew.

According to a second aspect of the present invention, the exhaust fan is a sirocco fan, and the air in the fermenter is sucked from the inlet on one side and the air between the fermenter and the casing is sucked from the inlet on the other side. Since both are mixed and discharged from the exhaust port, it is not necessary to provide an exhaust fan for exhausting the air in each space in the garbage disposal machine, and only one fan is required, so that a compact configuration can be achieved. Costs can be kept low.

According to a third aspect of the present invention, a shutter is disposed at the intake port to change the mixing ratio. Therefore, the mixing ratio can be changed according to the type of garbage and the installation location. Optimal internal ventilation can be performed.
