The specific operation is as follows.
Approach each other, the lower end is crushed, the duct 53 is closed, and the communication between the duct 53 and the microorganism container 15 is interrupted. On the other hand, when the arm portion 56 separates,
The duct portion 53 is elastically restored, and the inside of the duct portion 53 and the inside of the microorganism container 15 communicate with each other. Further, a filter member 57 for removing foreign substances is provided between the suction port 51a and the discharge port 50a in the duct 53. In the present embodiment, the filter member 57 is made of a punched metal in which a plurality of holes are formed in a plate made of stainless steel, which is a metal having excellent corrosion resistance.

Next, the garbage disposal process of the above garbage disposal apparatus will be described. The garbage processing apparatus is configured to automatically perform garbage processing by the control device 100 shown in FIG. Hereinafter, the process of processing garbage by the control device 100 will be described in order. FIG. 3 is a time chart showing the garbage disposal process. First, as the garbage accumulates in the drainage section, the water in the garbage naturally flows out from the plurality of small holes formed in the drainage section to the discharge path 8 to drain the garbage. Is performed.

When the user wants to dispose of the garbage deposited in the draining section, the user depresses the foot pedal 4 to activate the opening / closing gate 7 to open the slot 6. Then, the draining section is removed upward, and the garbage in the draining section is transferred from the input port 6 through the transfer path 5 to the pulverizing section 11.
Down into it. Next, release your foot from the foot pedal 4,
The opening 6 is closed by the opening / closing gate 7 (time t in FIG. 3).
1).

Then, the control device 100 controls the open / close gate 7
Determines that the opening 6 has been changed from the opened state to the closed state, and automatically rotates the crushing motor 13 of the crushing unit 11 for a predetermined time (two minutes). Then, the garbage is finely crushed by the crushing blade 12, and the crushed garbage is transported by the impeller 30 so as to blow out to the left in FIG. The open / close state of the open / close gate 7 is detected by a switch element (not shown).

At the time t1 when the opening / closing gate 7 is changed from the open state to the closed state, the electric motor 52 of the suction blower 51 is operated, and the arms 56 are operated so as to approach each other to open the garbage inlet 15a. close. Thereby, the crushed garbage is sucked and transferred into the duct 53 through the transfer pipe 50. In this example, the transfer pipe 5
The upstream side of 0 is not only connected to the pulverizing section 11 but also
Since the air intake 57 is formed separately on the downstream side of the impeller 31, air can be satisfactorily sucked in by the suction blower 51 and garbage can be sucked and transferred.

In the present invention, since the discharge port 50a of the transfer pipe 50 is connected below the suction port 51a of the suction blower 51, the garbage transferred into the duct 53 is directed toward the suction port 51a. Without being transported, it falls downward by its own weight as shown by arrow B in FIG. That is,
In this example, after the garbage is suction-transferred to a portion below the suction port 51a in the duct portion 53 by the suction blower 51,
The garbage is dropped to the microorganism container 15 side by its own weight.

At this time, since the garbage inlet 15a is closed, the duct portion 53 stores the garbage transferred from the transport pipe 50. That is, the duct part 53 constitutes the garbage storage part 53 'of the present invention. Thereafter, the crushing motor 13 is operated for one minute, and at time t2 in FIG. 3, the crushing motor 13 is stopped. Here, at time t2, the suction blower 51 is still operating, the arm 56 is closed at the garbage intake 15a, and has been operating for one minute after the crushing unit 11 is stopped. That is, from time t1 to time t3, the blower 51 is on and the arm portion 56 is kept closed.

At time t3, the arms 56 separate from each other to open the garbage intake 15a, the suction blower 51 stops, and the suction of garbage is terminated.
0 is automatically activated for 2 minutes, and the stirring blade 18 rotates until time t4. That is, when the suction of the garbage is completed, the garbage intake 15a is opened by the arm 56, and the garbage stored in the duct 53 falls into the microorganism container 15.

The garbage falling into the microorganism container 15 is stirred with the microorganism carrier 31 by the stirring blade 18 to efficiently
Decomposed into water. The stirring motor 20 operates for two minutes every two hours as described above without depressing the foot pedal as described above, and also operates when the foot pedal is operated as described above. . And
The decomposed gas generated by this decomposition is removed from the odor by the ventilation pump 24 and the deodorizing device 23 and discharged to the atmosphere. Further, the air containing the off-flavor of the garbage sucked into the suction blower 51 is also discharged into the atmosphere after the off-flavor is removed by the deodorizing device 23.

As described above, in this embodiment, the garbage is sucked and transferred to the lower part of the suction port 51a in the duct 53 by the suction blower 51, and then the garbage is dropped into the microorganism container 15 by its own weight. Garbage does not flow in the suction blower 51. As a result, the durability of the suction device for sucking garbage can be improved. Further, in this example, the suction blower 51 sucks only the crushed garbage and air without supplying water to the garbage unlike the conventional apparatus, and the garbage and air are stored in the microorganism container 15. Can be transferred to For this reason, it is possible to prevent water quality deterioration with a simple configuration without using a septic tank or a heating device for evaporating water. Also,
In consideration of the durability and the decomposability of the microorganism carrier 31, it is preferable that water is not contained in the microorganism container 15 as much as possible.
For this reason, in this example, the microorganism carrier 3 is larger than the conventional device.
1 can improve durability and decomposition ability.

In this example, even if fine garbage is transferred into the duct 53, for example,
7 can prevent the suction suction blower 50 from being sucked. The garbage clogged in the filter member 57 can be naturally dropped into the microorganism container 15 when the garbage intake 15a is open and the suction blower 51 is stopped.

In the present invention, as shown in FIG. 4, the arm portion 56 is not provided, and the connection port 50a and the garbage intake port 1 are always provided.
5a may communicate with it. However, in this case, there is a problem that the microorganism carrier 31 is wiped upward by the suction blower 51. Therefore, in this example, when the suction blower 51 is operating, the garbage intake 15a
Is always closed, so that the microbial carrier 31 can be prevented from blowing up, and only the crushed garbage and air can be sucked.

(Other Embodiments) In the above embodiment, for example, when water work is performed using a water supply (not shown) in a kitchen cabinet, when the inlet 6 is opened at the opening / closing gate 7, water is supplied to the inlet. Step into 6. Therefore, there is a problem that the water enters the microorganism container 15 through the transport pipe 50. Therefore,
An electromagnetic valve may be provided in a water supply pipe or the like, and when the opening / closing gate 7 is open, the electromagnetic valve may be closed to prevent intrusion of water from the water supply.

In the above-described embodiment, the garbage disposal apparatus 1 is applied to a so-called built-in type which is installed below the sink 1 in a kitchen cabinet.
The present invention is not limited to this, and can be applied to any garbage disposal apparatus. Further, in each of the above embodiments, the garbage is crushed by the crushing unit 11 and then transferred into the microorganism container 15, but the present invention can be applied even without the crushing unit 11.

In each of the above embodiments, the microorganism carrier and the garbage are agitated by the agitating blade 18, but the present invention can be applied even without the agitating blade 18. In each of the above embodiments, a centrifugal blower is used as the suction means, but the present invention is not limited to this, and any suction means may be used.
