DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust treatment mechanism of a garbage disposal apparatus for composting garbage discharged from a home kitchen or the like by fermentation and decomposition.

[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. In this type of garbage disposer, the periphery of a fermentation tank serving as a container is covered with an outer frame, and a stirring claw shaft is inserted horizontally in the upper, lower, left, and right central portions of the fermentation tank, and laid horizontally. When a nail is planted and agitated by rotating it in the fermentation tank, and aerobic bacteria or a water regulator that promotes fermentation are added to this fermentation tank together with the garbage, the garbage is crushed. While being stirred, the garbage is decomposed by the bacteria, and the added garbage is further decomposed. The air containing the odor generated by the fermentation decomposition treatment is discharged to the outside of the processing machine as it is through the exhaust fan, or is discharged after the deodorization treatment using a deodorizing device attached to the main body of the processing machine.

[0003]

Although the fermenter has a closed structure to prevent odor leakage, the collection tray is not provided with any mechanism for preventing odor leakage. For this reason, odors may be generated from the compost or the raw garbage stored in the collection tray having a high water content and falling from the fermenter without undergoing the fermentation decomposition treatment, and insects may approach the garbage.

In the above-mentioned conventional garbage processing machine, when a deodorizing device using a thermal catalyst is used as a deodorizing device for exhausted air containing odors discharged from a fermenter, the present invention requires a high temperature. Exhaust gas to the collection tray,
Used to dry compost and garbage to prevent insects from approaching,
In addition, the temperature of the exhaust gas, which is too high to be discharged to the outside as it is, is to be reduced.

[0005]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. Claim 1 is a garbage disposal machine equipped with a fermenter for fermenting and decomposing garbage and a collection tray for storing garbage processed below the garbage, which contains an odor generated after the fermentation and decomposition. The exhaust gas is deodorized in an exhaust processing unit having a thermal catalyst, and the exhaust gas after the deodorization process is sent to the collection tray.

According to a second aspect of the present invention, the exhaust processing section is arranged on one side and the collecting tray is arranged on the other side, and the exhaust processing section and the collecting tray communicate with each other through an air path, and the exhaust air is reduced to a predetermined temperature in the air path. I did it.

Next, an embodiment of the present invention will be described. 1 is a perspective view of the garbage disposal machine, FIG. 2 is a front sectional view thereof, FIG. 3 is a right sectional view thereof, FIG. 4 is a bottom view thereof, and FIG. 6 is a left side view, partly in section, showing the configuration of a shutter receiver below the fermenter, FIG. 7 is a front view showing a thermal catalyst deodorizer, and FIG. 8 is a thermal catalyst deodorizer. FIG. 9 is a rear view showing the thermal catalyst deodorizer.

The overall configuration of the garbage disposal machine of the present invention will be described with reference to FIGS. 1, 2 and 3. The garbage disposal machine 9 includes a U-shaped fermenter 1 in a casing 10 for fermenting garbage in a side view, and a collecting tray disposed below the garbage for collecting the final residue processed by the fermenter 1. 29, and an exhaust processing section 20 for performing a deodorizing treatment of odors generated from garbage processed by the fermenter 1.

The casing 10 is formed of a synthetic resin,
It has a rectangular box shape in which the front and rear walls and side walls are erected from the front and rear and left and right of the base 10c serving as a base and the upper part is opened. As shown in FIGS. 1, 2 and 3, the casing 10
The upper open portion is a garbage input port 10a and is closed by an input lid 12, which is pivotally supported on a rear edge so as to be openable and closable vertically. An operation panel 13 is mounted on the upper surface of the casing 10. In addition, operations such as starting and stopping the fermentation and pulverization processing can be performed. A controller is housed in the operation panel 13 to control driving of the stirring claw shaft 19 and the like.

Further, a pair of left and right support stands 56, 56
Are erected from the left and right sides of the bottom 10c of the casing 10, and bosses 14, which are screwed and fixed to the center of the left and right side surfaces of the fermenter 1, respectively, are provided at the upper centers of the support stands 56.
14 are placed, and both sides of the stirring claw shaft 19 are rotatably inserted and supported in the axial center portions of the bosses 14.

As shown in FIG. 4, an outlet 10d is opened at the lower left side of the front wall 10b of the casing 10, and the outlet 10d is covered by a detachable discharge door 16, By opening the fermenter 1
The collection tray 29 arranged below the lower discharge port 1b can be pulled out.

As shown in FIGS. 2 and 3, the fermenter 1 has a substantially rectangular parallelepiped shape and is formed longer in the axial direction of the stirring claw shaft 19 to increase the internal volume. The fermenter 1 is U
The stirring claw shaft 19 is inserted in the left-right direction at the center of the lower semicircular portion. A plurality of stirring claws 18 are arranged at predetermined intervals in the left-right direction on the stirring claw shaft 19 and are shifted by a predetermined angle around the stirring claw shaft 19.
The bottom of the fermentation tank 1 is located at the lower and outer position of the rotation trajectory of the tip of the stirring claws 18.

The upper part of the fermenter 1 is opened and the input port 1 is opened.
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.

Now, the exhaust treatment mechanism of the present invention will be described. In the fermenter 1, suction ports 1h, 1h capable of inhaling outside air are opened at an upper portion of one side surface.
An exhaust port 1 a is provided on the side opposite to h · 1 h, and is connected to the exhaust processing section 20. As shown in FIG. 5, the exhaust processing unit 20 includes an exhaust fan 21, an exhaust duct 22, a thermal catalyst deodorizer 50, an exhaust duct 23, and the exhaust duct 22.
The exhaust processing unit 20 is arranged on one side on the left and right sides (right side), and the collection tray 29 is arranged on the other side (left side) and positioned on the opposite side, It is configured to communicate with the exhaust duct 23. An exhaust fan 21 serving as an exhaust unit is screwed and fixed to an outer surface of the exhaust port 1 a of the fermenter 1, and a discharge port of the exhaust fan 21 is connected to an exhaust duct 22 downward. The exhaust duct 22, the thermal catalyst deodorizer 50, and the exhaust duct 23 form a closed exhaust path, and the end of the exhaust duct 23 is connected to a shutter receiver 31 provided on the upper surface of the collection tray 29. ing.

As shown in FIGS. 1, 5 and 6, the collection tray 29 has a shutter holder 3 as described below.
1 and the like, the left side is covered with the casing 10 on the side plate 71 disposed on the bottom 10c, the front and rear bottom surfaces and the right side are covered with the casing 10. With this arrangement, the collection tray 29 is confined in a substantially hermetically closed space, and leakage of the exhaust gas flowing through the exhaust path to the inside of the garbage disposal machine 9 is prevented. A shutter 30 is provided below the fermenter 1 so as to cover the outlet 1b at the lower part of the fermenter 1, and is supported by a shutter receiver 31 that guides the shutter 30 slidably back and forth. The shutter receiver 31 is a flat sheet metal, and a drop port 31b, which is a hole larger than the discharge port 1b, is provided at the center so that the processed material can drop from the fermenter 1 to the collection tray. The shutter receiver 31 is supported by a flat support seat 33 screwed and fixed to bosses 1c and 1d planted laterally below the fermenter 1. That is, the upper surface is sealed by the above configuration. At the rear of the upper surface of the shutter receiver 31, the end of the exhaust duct 23 is connected to the left, and an exhaust duct 70 is connected to the right, and the end of the exhaust duct 70 is provided on the rear wall 10e of the casing 10 at the rear. The mouth 83 is fitted.

When the exhaust fan 21 is driven, outside air is sucked into the fermenter 1 from the inlets 1h, 1h, and air (oxygen) is placed on the upper surface of the processed material stirred by the stirring claws 18, 18,. And exhaust containing gas generated during fermentation and moisture in the processed product is sucked from the exhaust port 1 a by the exhaust fan 21 and discharged to the exhaust processing section 20. Next, the exhaust gas is subjected to a deodorizing process by the thermal catalyst deodorizer 50 of the exhaust processing section 20.

This thermal catalyst deodorizer 50 comprises a heater 51 formed in a U-shape and a case 52 containing the heater. As shown in FIGS. 7 to 9, the inside of the case 52 is configured to match the shape of the heater 51, and a U-shaped hollow space is formed. Here, assuming that the surface where the exhaust gas flows into the thermal catalyst deodorizer 50 is the front, two intake ports 52a are opened in a front view, and one exhaust port 52b is opened on the rear surface.

The heater 51 is a heating wire, and generates heat by passing an electric current. The generated heat causes the metal constituting the heating wire to function as a catalyst. With this function, the heater 51 promotes a thermal decomposition reaction of the exhaust gas to perform a deodorizing treatment. However, the heater 51 can be a sheathed heater, a halogen heater, or the like, and is not limited. An advantage of the above configuration of the thermal catalyst deodorizer 50 is that the wiring of the wiring is easy because the heater 51 is formed in a U-shape. In addition, since the case is configured so that the exhaust gas passes near the heater, the temperature of the exhaust gas can be efficiently increased and the deodorizing process can be performed. In addition, since the heater 51 has a U-shape and forms a reciprocating circuit, the heat retaining effect is high, and the deodorizing effect is exhibited when operated with low power. Further, for the same reason, the time required for raising the temperature is short, so that the deodorizing performance can be exhibited early.

The exhaust gas passing through the thermal catalyst deodorizer 50 is:
The air is discharged toward the inside of the collection tray 29 through the exhaust duct 23 and the shutter receiver 31. Although the exhaust gas has a high temperature due to the passage through the thermal catalyst deodorizer 50, the exhaust gas passes through a relatively long path such as the exhaust duct 23, so that the temperature of the exhaust gas can be reduced to a predetermined temperature that does not deform peripheral devices. In the collection tray 29, the compost dropped from the fermentation tank 1 by sliding the shutter 30 after the fermentation decomposition treatment is completed, and the compost overflowing from the fermentation tank 1 are unprocessed raw materials. There is a possibility that dust and the like may be mixed, and these have a relatively high moisture content. However, the warm exhaust air cooled to a certain degree is sent to the collection tray 29 to dry the processed matter having a large amount of water. The air that has passed through the collection case 29 is discharged to the outside of the garbage disposal machine 9 from the exhaust port 83 via the exhaust duct 70.

[0020]

As described above, the present invention has the following advantages. That is, a garbage disposal machine 9 internally provided with a fermenter 1 for fermenting and decomposing garbage and a collection tray 29 for storing the garbage processed below the fermenter as claimed in claim 1. Exhaust gas containing odor generated later is deodorized in the exhaust processing unit 20 having a thermal catalyst, and the exhaust gas after the deodorizing process is blown to the collection tray. By blowing high-temperature exhaust air to the stored high-moisture-content compost or raw material, moisture can be dried, thereby preventing the generation of odor and the approach of insects.

According to a second aspect of the present invention, the exhaust processing section is disposed on one side and the collecting tray is disposed on the other side, and the exhaust processing section and the collecting tray are communicated with each other through an air path. Since the temperature is lowered, the temperature of the exhaust gas can be effectively lowered, and the surrounding devices are not melted or deformed.
