DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for processing garbage discharged from a kitchen or the like.

[0002]

2. Description of the Related Art As a prior art, for example, Japanese Patent Application Laid-Open No. H10-4
No. 42 discloses a garbage processing machine. This garbage disposer is equipped with a microbial decomposition tank for decomposing crushed garbage by microorganisms. The outside air (air in the living room) is passed through the microbial decomposition tank to supply oxygen to the microorganisms, The gas generated by this is exhausted to the drain of the kitchen sink together with the outside air. In general, a kitchen sink drain pipe is connected to a drain pipe of a bathroom or a washroom in a detached house, and is connected to a kitchen sink drain pipe of another house in an apartment house. Therefore, the gas exhausted to the drain of the kitchen sink is
The water is discharged from the kitchen sink drain through the drain inside the building to the outside of the building. The drain pipe of each room is provided with a water-sealing trap that shuts off the inside of the drain pipe and the living room by sealing the water as a means for preventing a bad smell from flowing backward from inside the drain pipe into the living room.

[0003]

However, the structure in which the gas generated by the decomposition is exhausted together with the outside air to the drain of the kitchen sink has the following problems. If the resident does not use water for a long period of time due to travel, etc., the water in the trap will evaporate or the trap will break due to pressure fluctuations in the drain pipe, etc. The jurisdiction and the room are connected. Under such circumstances, when gas generated by the decomposition of garbage from the garbage disposer is released into the drain of the kitchen sink, the generated gas enters the living room in which the water seal trap has been broken, and the odor is smelled. This is a hygiene problem. The present invention has been made based on the above circumstances,
An object of the present invention is to provide a garbage disposer capable of preventing gas generated by decomposition of garbage from entering a living room even when a water sealing trap of a drain pipe is broken.

[0004]

(Means for Solving the Problems) A drain passage for draining water generated during the processing of garbage, an exhaust passage for discharging gas generated by decomposition of the garbage, Backflow prevention means for preventing gas from flowing back through the exhaust passage is provided, and the drain passage and the exhaust passage are each configured as an independent system. Accordingly, the gas discharged to the exhaust passage does not flow to the drain passage, and even if the drain trap provided in the drain passage is broken, there is no fear that the gas enters the living room. Further, by providing the backflow prevention means in the exhaust passage, it is possible to prevent the gas discharged to the exhaust passage from flowing back and entering the living room.

(Means for Claim 2) An indoor exhaust pipe is provided for exhausting gas generated in the garbage decomposition tank, and the indoor exhaust pipe is connected to a collective exhaust pipe provided exclusively for exhaust, and the collective exhaust pipe is provided. Backflow prevention means for preventing gas from flowing back from the garbage to the garbage decomposition tank. According to this configuration, the gas generated by the decomposition of the garbage can be reliably discharged to the outside (outdoor) from the collective exhaust pipe dedicated to exhaustion, and the gas can be prevented from flowing into the drain passage. As a result, when the water is not used for a long period of time, even if the drain trap provided in the drain passage is opened, there is no possibility that gas enters the living room. Also, by providing a backflow prevention means,
Gas can be prevented from flowing backward from the collective exhaust pipe to the garbage decomposition tank, and gas discharged from another living room or another house can be prevented from entering the living room through the collective exhaust pipe.

(Means of Claim 3) The backflow prevention means can be provided in an indoor exhaust pipe.

The ventilating means has a ventilating pump provided with a backflow preventing means.

[0008] (Means of Claim 5) The collecting exhaust pipe has one end side extending downward and communicating with the sewer pipe. The gas generated by the decomposition of garbage contains a large amount of water, and dew forms during discharge. Since this dew water contains dissolved odorous components (ammonia, trimethylacine, etc.), it is not preferable in terms of environmental health to directly discharge it to the surface of the earth. Therefore, by connecting one end of the collective exhaust pipe to the sewer pipe,
Condensation water can flow down the sewer.

(Means of Claim 6) One end of the collective exhaust pipe is
It is connected via a drain trap to a drain tank for temporarily storing the drainage flowing into the drain passage. Condensed water can flow to the drainage tank by connecting the collective exhaust pipe to the drainage tank. However, if the collective exhaust pipe is connected directly to the drainage tank, the collective exhaust pipe and the drainage pipe of the building (drainage pipe) Because of this, the gas flowing from the collective exhaust pipe to the drainage tank may enter the living room through the drainage pipe. Therefore,
By providing a drain trap between the collective exhaust pipe and the drainage tank, gas flowing from the collective exhaust pipe to the drainage tank can be blocked by the drainage trap, so that gas can be prevented from entering the living room.

(Means of Claim 7) One end of the collective exhaust pipe is
The drainage tank is connected to a drainage tank for temporarily storing drainage flowing into the drainage passage, and is opened below the liquid level in the drainage tank. In this case, since the stored water in the drainage tank can fulfill the function of a drainage trap, the gas does not flow from the collective exhaust pipe into the drainage tank as in the case of claim 4, and the gas into the living room does not flow. Can be prevented from entering.

As a result, the gas can be prevented from flowing into the drain passage, and the drain traps 19a, 20a, and 21a provided in the drain passage are opened when the user does not use water for a long time. Also, there is no danger of gas entering the living room. Further, since the check valve 28 is provided on the indoor exhaust pipe 26, it is possible to prevent the gas from flowing backward from the collective exhaust pipe 27 to the indoor exhaust pipe 26. As a result, it is possible to prevent gas discharged from another room or another house from entering the room through the collective exhaust pipe 27.

Further, since the collective exhaust pipe 27 is connected to the drainage mass 23, when moisture contained in the gas is condensed in the exhaust passage (the indoor exhaust pipe 26 and the collective exhaust pipe 27), the dew water is drained. It can flow to the mass 23. This dew water contains odor components (ammonia, trimethylacine, etc.)
Although it is not preferable from the viewpoint of environmental health to discharge the dew water directly to the ground surface because the water is dissolved, it is possible to prevent the dew water from being discharged to the ground surface by flowing the water to the drainage mass 23 as described above. The above problems can be avoided.

However, the collective exhaust pipe 27 is directly connected to the drain
When the connection is made, the collective exhaust pipe 27 and the drain passage are connected via the drain mass 23, and therefore, the gas flowing from the collective exhaust pipe 27 to the drain mass 23 may enter the living room through the drain passage. is there. On the other hand, in this embodiment, the drain trap 30 is

In the above embodiment, the check valve 28 is provided in the indoor exhaust pipe 26 in order to prevent the gas from flowing backward from the collective exhaust pipe 27 to the garbage decomposition tank 4. A prevention mechanism may be provided. In this case, the check valve 28 of the indoor exhaust pipe 26 can be eliminated.

(Second Embodiment) FIG. 3 is a schematic diagram showing a connection relationship between the collective exhaust pipe 27 and the drainage mass 23. The present embodiment shows an example in which the collective exhaust pipe 27 is directly connected to the drain mass 23 without providing the drain trap 30 described in the first embodiment. However, the collective exhaust pipe 27 is not shown in FIG.
As shown in (2), it is connected below the liquid level in the drainage mass 23. In this case, since the stored water in the drainage mass 23 can perform the same function as the drainage trap 30, no gas flows from the collective exhaust pipe 27 into the drainage mass 23 as in the first embodiment. Gas can be prevented from entering the living room from the drainage mass 23 through the drainage passage.
