Reference numeral 57 denotes a sheet-like insect repellent, which is mounted on the inner surface of the lid 52 and is located above the opening 37, and is formed by mixing a pyrethroid-based component with a synthetic resin such as a polyolefin resin. Since the pyrethroid component evaporating from the water has a specific gravity eight times that of air, it sinks toward the opening 37 and prevents the pests generated in the processing tank 1 from going out through the opening 37 to the garbage input port 35 side. At the same time, pests that have emerged are controlled by pyrethroid-based components. Therefore, even when the lid 52 is opened when exhausting the garbage, the pests do not fly out and the user does not feel uncomfortable.

By maintaining an interval between the cover 52 and the cover 52, the transpiration property is improved.

Next, the circuit will be described with reference to FIG.
63 is a switch circuit having a switch mounted on the substrate 40, 64 is detection means such as a micro switch for detecting the opening of the lid 52, and 65 is a signal from the switch circuit 63, the detection means 64 and the temperature sensor 42. A control circuit composed of a microcomputer to be input, a motor drive section 66 for controlling the drive of the motor 10, a first heater control section 67 for controlling the energization of the first heating means 21, and a second control section for controlling the energization of the heater 27 of the second heating means 24. The two-heater control unit 68 is controlled.

When processing the garbage, the lid 52 is opened, the garbage is dropped from the garbage inlet 35 onto the inclined surface 36, and the garbage is poured into the processing tank 1 together with water. At this time, the lid 52 is opened so as to cover the operation unit 49 as shown in FIG.
The operation unit 49 is not accidentally operated with the lid 52 opened. Further, even if the operation unit 49 is operated with the lid 52 opened, the detecting means 64 detects the opening of the lid 52, and the control circuit
Since the power supply to the electric motor 10 is stopped at 65, the stirring blade 11 does not rotate with the lid 52 opened.

When the input of the kitchen waste is completed, the lid 52 is closed and the operation unit 49 is operated. In this state, the control circuit 65
Receives a signal indicating that the lid 52 is closed from the detection means 64, rotates the electric motor 10 forward by operating the operation unit 49, and rotates the stirring blade 11 in the direction of the solid arrow shown in FIG. Stirrer blade 11
Is rotated toward the V-shaped ridge of the stirring blade 13, so that the garbage and the carrier 3 are easily pushed in the axial direction, and rotate with a relatively small load. Further, since the stirring blade 13 is curved toward the ridge line, the garbage located on the carrier 3 is efficiently drawn into the carrier 3 and efficiently mixed with the carrier 3 in a short time. Further, since the stirring blades 13 are arranged in a spiral shape, the kitchen waste and the carrier 3 are moved not only in the rotation direction but also in the axial direction to stir, thereby further improving the stirring efficiency.

The control circuit 65 stops the operation when the motor 10 is rotated forward for a predetermined time, for example, 20 seconds in the present embodiment, and after a predetermined time until the motor 10 is completely stopped, 5 seconds elapse in the present embodiment. Thereafter, the electric motor 10 is rotated in the reverse direction, and the stirring blade 11 is rotated in the direction of the dashed arrow shown in FIG. The control circuit 65 reversely rotates the motor 10 after the motor 10 is completely stopped.
No back electromotive force is generated at the time of startup, and the durability of the electric motor 10 can be improved. In the reverse rotation state of the electric motor 10, the stirring blade 13 stirs the garbage and the carrier 3 while pushing them to the outer periphery, and crushes the garbage with the side wall of the processing tank 1. In this rotation direction, the load is larger than in the rotation in the normal rotation direction, but the crushing ability is improved.

When the control circuit 65 reversely rotates the motor 10 for a predetermined time, in this embodiment, for 20 seconds, it rotates forward again after the predetermined time until the motor 10 is completely stopped. The normal rotation and the reverse rotation are alternately repeated, and the operation is stopped after a lapse of a total of 20 minutes.

On the carrier 3 of the processing section 4, bag-shaped animals such as nematodes and wheelworms, and microorganisms such as protozoa and bacteria, which adhere to the garbage due to the disposal of the garbage into the treatment tank 1, propagate. Mainly bag-shaped animals and protozoa eat and destroy kitchen waste. Since the garbage discarded in the processing tank 1 is crushed between the stirring blade 11 and the side wall of the processing tank 1, it is eliminated in a relatively short time. Further, since the carrier 2 is maintained at a temperature at which the bag-shaped animal and the microorganism are activated by the first and second heating means 21 and 24,
The bag-shaped animals and microorganisms are activated, and the efficiency of decomposition processing of kitchen garbage is further improved.

The water supplied to the treatment tank 1 together with the garbage is
The garbage passes through the purification section 5 together with the water generated by decomposing the garbage, and is drained to the drain section 28. This water contains ingredients that occur in the process of completely decomposing kitchen garbage, that is, sugars,
It contains amino acids, organic acids, and the like, and this component is decomposed by microorganisms, especially bacteria, that propagate on the carrier 3 of the purification section 5, purified, and drained to the drain section 28. In addition, waste and dead bodies of the bag-shaped animals and microorganisms are also decomposed by bacteria.
In addition, the above-mentioned components, wastes and dead bodies of bag-shaped animals and microorganisms,
It is also decomposed by bacteria propagated on the carrier 3 of the processing section 4. It can be almost completely decomposed with almost no odor and residue due to the food chain of the bag-shaped animal and the microorganism.

The water discharged to the drain 28 is drained from a drain hose through a drain 32. If the partition plate 29 that partitions the drainage section 28 is clogged,
31 Remove the watering hose connected to the
Through the sprinkler hose and washed with water from a watering hose.

Since the carrier 3 is composed of wood chips, it is hardly decomposed by microorganisms, but is reduced by long-term use due to factors such as flowing out with drainage. When the upper reinforcing portion 2 is visible from the carrier 3 when the shutter 38 is opened and the inside of the processing tank 1 is viewed, the loading guide 69 shown in FIG. As shown in FIG. 14, the carrier 3 is mounted so as to cover the lid 52, and the carrier 3 is appropriately replenished using the introduction guide 69 and the inclined surface 36 as guides. Since the loading guide 69 is mounted so as to cover the lid 52, the carrier 3 does not enter the opening / closing detection means side of the lid 52 along the operation piece 53 of the lid 52, and the rotation of the lid 52 There is no occurrence of a failure or a failure in detecting the opening and closing of the lid 52. The loading guide 69 is, as shown in the packaged state shown in FIG.
Along with the notch 71 formed in the, the strength of the side surface is reinforced by maintaining the interval between the upper cushions 70,
The upper surface is reinforced.

[0032]

As described above, according to the structure of the first aspect of the present invention, the volume of the carrier in the treatment tank can be reliably confirmed with a simple structure, and the deterioration of the garbage decomposition ability due to the shortage of the carrier can be prevented. It is possible to maintain a high kitchen waste disposal capacity.

According to the second aspect of the present invention, the volume of the carrier in the processing tank can be reliably confirmed with a simple configuration by using the reinforcing portion for reinforcing the processing tank. This has the effect of preventing a reduction in the kitchen garbage decomposition capacity and maintaining a high kitchen garbage processing capacity.
