By stopping the air conditioner 24 and driving the blower 26, it is possible to prevent the malodor in the processing tank 5 from leaking from the disposal port 34 and prevent the user from feeling uncomfortable.

When the lid 36 is closed and the operation switch 37 is operated, the electric motor 8 is driven for about 1 minute, the kitchen blades are mixed with the carrier 6 by the rotation of the stirring blade 11, and the carrier 6 is stirred into the carrier 6. Supply air. In addition, the pump 24 operates based on the output of the detection sensor 38 to supply air into the treatment tank 5 and evaporate the excess water contained in the carrier 6 to evaporate bag-shaped animals and microorganisms that propagate on the carrier 6. Activate. Since the small hole of the air supply pipe 23 is formed downward, water does not enter the air supply pipe 23 through the small hole.

The stirring blade 11 is driven every predetermined time based on the output of the control circuit 40, in this embodiment, every 4 hours, and air is supplied into the carrier 6 to activate the saprophytes and microorganisms. .

On the carrier 6, bag-shaped animals such as ringworms and nematodes attached to the kitchen waste by disposal of the garbage into the processing tank 5 and microorganisms such as protozoa and bacteria are propagated, and mainly the ringworms. Worms and nematodes and protozoa eat and dispose of garbage. The pump 24 and the blower 26 supply the optimum air for breeding bag-shaped animals and microorganisms to the treatment tank 5 and maintain the optimum humidity. Therefore, the kitchen waste to be disposed of in the treatment tank 5 is relatively small. It decomposes and disappears in a short time.

The water produced by decomposing the garbage is
The kitchen waste contains components that are produced in the process until it is completely decomposed into water and carbon dioxide, that is, sugars, amino acids, organic acids, etc., but these components are decomposed by microorganisms, particularly bacteria, that propagate on the carrier 6. , Purify and drain. Also, wastes and carcasses of bag-shaped animals and microorganisms are decomposed by bacteria. The purifying action of the wastewater is performed in the entire treatment tank 5, and the portion of the carrier 6 that is not stirred by the stirring blades 11 is necessary to make the wastewater more purified. Due to the food chain of the above-mentioned bag-shaped animals and microorganisms, it can be almost completely decomposed without producing malodor and residues.

When the temperature in the processing tank 5 detected by the temperature sensor 22 becomes 25 degrees Celsius or less, the first heating means 16 and the second heating means 20 are energized to heat the inside of the apparatus main body 1 by the second heating means 20. , The first heating means 16 and the second heating means 20 maintain the carrier 6 in the treatment tank 5 at a temperature of 25 to 40 degrees Celsius, which is the optimum temperature for the activity of the pouch animals and microorganisms, and activate the pouch animals and microorganisms. To maintain the good efficiency of kitchen waste decomposition treatment.

Since the kitchen waste is mixed with the carrier 6 by the rotation of the stirring blade 11, it is located within the range where the stirring action of the stirring blade 11 is exerted and decomposed within that range. The range of the stirring action of the stirring blade 11 is the range in which the stirring blade 13 of the stirring blade 11 and the kitchen garbage that moves with the rotation of the stirring blade 13 affect,
The projection range of the rotation trajectory of the stirring blade 11 and its vicinity, in other words, the stirring range of the stirring blade 11 and its vicinity. Therefore,
By disposing the temperature sensor 22 in the range of the stirring action of the stirring blade 11 and its vicinity, that is, in a position in the range of the stirring action of the stirring blade 11 which is affected by the heat generated by the decomposition of the garbage, the treatment is performed. The first heating means 16 and the second heating means 20 are controlled so as to detect the temperature of the carrier 6 in the portion that most contributes to the decomposition in the tank 5 so that the temperature is suitable for the activation of the saprophytes and microorganisms. be able to.

Since the garbage mixed with the carrier 6 by the stirring blade 11 sinks downward in the stirring range of the stirring blade 11 as the stirring blade 11 rotates, in the stirring range of the stirring blade 11 or in the vicinity thereof, Moreover, the position of the stirring blade 11 below the rotary shaft 12 is the portion that most contributes to the decomposition of the garbage. Further, the upper part of the carrier 6 is easily affected by the outside air temperature due to the air blow of the air blower 26 and the temperature inside the processing tank 5 may not be accurately detected. Therefore, by arranging the temperature sensor 22 in the stirring range of the stirring blade 11 and its vicinity and below the rotating shaft 12 of the stirring blade 11, it is optimal for controlling the first heating means 16 and the second heating means 20. It can detect various temperatures.

Since the carrier 6 has relatively poor heat conduction, the stirring blade
The temperature becomes higher toward the center of the stirring range of 11, and is less susceptible to the outside air temperature. Therefore, by disposing the temperature sensor 22 near the side wall of the processing tank 5,
It is possible to reliably and quickly detect changes in the outside temperature.

The recess 21 has a side surface on which the stirring blade 11 comes closer than the temperature sensor 22 as the stirring blade 11 rotates.
Since the temperature sensor 22 is close to the rotation locus of the stirring blade 11, the temperature sensor 22 is covered by the recess 21 in the rotation direction of the stirring blade 11, and the garbage moving with the rotation of the stirring blade 11 causes the temperature sensor 22 to move. A temperature sensor that can prevent collisions
It is possible to prevent damage to 22 and water leakage from the mounting portion of the temperature sensor 22.

Further, since the disposal port 34 is arranged on the back side of the apparatus main body 1 and the temperature sensor 22 is arranged on the front side of the apparatus main body 1, the temperature sensor 22 is arranged so as to be displaced from the projection position of the disposal port 34. It is possible to reliably detect the temperature in the treatment tank 5 without being affected by water and the like which are discarded in the treatment tank 5 together with the garbage from 34.

FIG. 7 shows a second embodiment of the present invention, in which the recess 21
The mounting surface of the temperature sensor 22 is tilted so that the temperature sensor 22 tilts in a direction away from the stirring blade 11. According to the configuration of the second embodiment, it is possible to more reliably prevent the garbage moving with the rotation of the stirring blade 11 from colliding with the temperature sensor 22. Moreover, since the mounting surface of the temperature sensor 22 of the recess 21 is inclined, the mounting workability of the temperature sensor 22 can be improved.

In the first and second embodiments, the temperature sensor 22 is arranged in the vicinity of the projected range of the rotation locus of the stirring blade 11, that is, in the vicinity of the lower outer periphery of the stirring range of the stirring blade 11, as shown in FIG. As in the third embodiment shown in FIG. 9, the temperature sensor 22 is attached to the stirring blade.
It may be positioned within the projection range of the rotation locus of 11, that is, on the side of the stirring locus of the stirring blade 11. The temperature sensor 22 has a recess 21.
The stirring blade 11 is attached to the side surface on the rotation direction side to prevent the garbage moving with the rotation of the stirring blade 11 from colliding with the temperature sensor 22.
