Each of the stirring pieces 4 is made of stainless steel, and each of the stirring pieces 4 rotates integrally with the rotating rod 3.
It is fixed to the rotating rod 3 via a member 3B.

Further, the inner casing 1 is rotatably supported on a stepped cylindrical outer casing 2 having a diameter reduced in accordance with the outer shape of the inner casing at the base end side. The support is performed by bringing the cylindrical outer peripheral surface of the inner casing 1 into contact with the inner peripheral surface of the reduced diameter portion of the outer casing 2. Therefore, the frictional force (rotational resistance) when the inner casing 1 rotates with respect to the outer casing 2 is set to be considerably larger than the frictional force (rotational resistance) when the rotating rod 3 rotates with respect to the inner casing 1. Have been. In the case of this embodiment, approximately 1.5 to 5
The rotation resistance is set to be about twice as large. Since the frictional force (rotational resistance) when the inner casing 1 rotates with respect to the outer casing 2 becomes a rotational torque necessary to destroy large garbage,
What is necessary is just to set appropriately according to what magnitude (large rigidity) garbage is destroyed within the range of the rotational torque allowed by the electric motor 5.

On the distal end surface of the outer casing 2, there is provided an openable / closable lid 2A integrally formed of transparent resin and configured to open and close around a hinge portion. Are sealed to the outside. In this embodiment, the lid 2A has a double structure so that dew condensation does not occur on the inner wall surface of the lid due to a temperature difference between the inside and the outside of the outer casing.

In the case of the household garbage disposal apparatus according to this embodiment, aerobic bacteria (microorganisms) are used for fermenting garbage. A suction port 9 for sucking outside air into the outer casing 2 is formed on a lower surface of the portion, and an electric fan 10 is disposed in the suction port 9 for forcibly sucking air.

Further, as shown in FIG. 1 or FIG. 6, a discharge port 11 for discharging the air inside the outer casing 2 to the outside is formed on the upper surface of the distal end of the outer casing 2. The outlet 11 is connected to a deodorizing filter unit 13 through a duct 12, and the electric fan 13 of the deodorizing filter unit 13 is connected.

A humidity sensor 15B for controlling the temperature and a control device C are provided. Further, as shown in FIG. 4, a mode change switch 16 and a mode instruction lamp 17 of the household garbage disposal device are arranged above the lid 2A of the household garbage disposal device. Between the lid 2A and the opening of the outer casing 2, the open / closed state of the lid 2A is detected and the main power supply is turned on / off.
An opening / closing sensor 18 also serving as a power switch is provided, and status indication lamps 19A and 19B inside the inner casing 1 are provided above the lid 2A opposite to the mode instruction lamp 17.

The household garbage disposal apparatus having the above configuration is covered with an outer panel 20, and the overall outer shape is
As shown in FIG. 2, the cover 2 </ b> A that opens to the front side around the lower end in FIG.

The household garbage disposal apparatus thus configured operates in the following manner in garbage disposal. Hereinafter, the operation of the household garbage disposal apparatus and the control contents will be described.

First, a base material (for example, sawdust or the like) mixed with bacteria (microorganisms) is put into the inner casing 1 and then the garbage to be treated is put into the inner casing 1 which is a fermentation tank. To

Next, when the lid 2A is closed, the open / close sensor 18 detects the "closed" state and the main power is turned on. In this state, when the mode change switch 16 is turned “ON”, the electric motor 5 rotates at a predetermined rotational speed (for example, 2 rpm).
(About 4 rotations). As a result, the rotating rod 3 rotates, and the garbage is stirred by the stirring piece 4 fixed to the rotating rod 3. Further, the temperature sensor 15A and the humidity sensor 15B detect the temperature and the humidity in the outer casing 2 and transmit the detected values to the control device C. The control device C turns on the electric heater H to heat the detected value to a predetermined temperature when the temperature is low in light of the previously stored temperature.
As described above, the electric heater H is controlled by the control device C.
When the temperature is lower than a predetermined temperature range, it is turned “ON”, and when it is within the temperature range, it is controlled to “OFF”.

When the humidity is high, the control device C operates the fans 10 and 13A on the suction port 9 and the discharge port 11 side to dry when the humidity is high. Control is performed to reduce the humidity by introducing the outside air and discharging the humid inside air. On the other hand, when the humidity is low in comparison with the humidity stored in advance, the status display lamp 19B is lit, and the humidification is performed to keep the humidity in order to keep the humidity at an appropriate level. In this case, the lid 2A may be opened to supply water to the inside. When the lid 2A is opened, the fan 1 on the discharge port 11 side must be opened.
3A is turned "ON", and a deodorizing operation is started in order to discharge air inside the outer casing 2 from the outlet 11 side as much as possible, not from the lid 2A side.

In the above situation, for example, when large garbage such as "sanma" is left alone in the garbage, the stirring piece 4
Comes into contact with the “sama”, and a large rotational load (rotational resistance) acts on the rotating rod 3. When the rotational load exceeds the frictional resistance between the inner casing 1 and the outer casing 2, the inner The casing 1 starts rotating together with the rotating rod 3 with respect to the outer casing 2.

And, as described above, the inner casing 1
Starts rotating (co-rotating) together with the rotating rod 3, the “sanma” rotates by scraping other garbage or the base material, and after a predetermined time (for example, 10 minutes) elapses,
"Sanma" is broken into two by the stirring piece 4 (mainly the stirring piece 4B). The same happens with the remaining destroyed "sama" or other large garbage,
The large garbage is gradually destroyed so as to have a size that does not hinder stirring, so that fermentation can be easily performed. Then, while the rotating rod 3 rotates in this manner and rotates in a predetermined temperature range and humidity range, bacteria in the base material adhere to and enter the garbage by the stirring piece 4, thereby causing fermentation. A state in which the processing is easily performed is formed. Then, when the rotating rod 3 rotates for a predetermined time (15 minutes in this embodiment), the electric motor 5 stops, and after a predetermined time (for example, 30 minutes: this time may be adjustable), The operation mode is entered again, and the electric motor 5 rotates the rotating rod 3. The above-mentioned temperature and humidity adjustment is performed even during the rotation or stop of the electric motor 5.

The household garbage disposal apparatus can completely ferment and decompose even large garbage by repeating the above process. Although it depends on the type of fungi (microorganisms), fermentation / decomposition treatment can be performed in about 24 hours, even if large garbage such as the above-mentioned "sama" is included. And what was processed in this way can be used as an organic fertilizer in a vegetable garden or the like.
