It is designed to let you.

Next, the circuit will be described with reference to FIG.
68 is a switch circuit having a switch mounted on the substrate 48, 69 is a detection means such as a micro switch for detecting the opening of the lid 58, and 70 is a first temperature sensor for detecting the temperature of the processing medium 2 of the processing section 3. , 71 is a second temperature sensor for detecting the outside air temperature, 72 is a control circuit consisting of a microcomputer for inputting signals from the switch circuit 68, the detecting means 69, the first temperature sensor 70 and the second temperature sensor 71, and the motor 9, a motor drive unit 73 for controlling driving, a first heater control unit 74 for controlling energization of the first heating unit 21, and a heater for the second heating unit 26.
The second heater control unit 75 for controlling the energization of 29 is controlled.

When the kitchen waste is processed, the lid 58 is opened, the kitchen waste is dropped from the kitchen input port 41 to the inclined surface 42, and the kitchen waste is poured into the processing tank 1 together with water. At this time, the lid 58 is opened so as to cover the operating portion 55 as shown in FIG.
The operation unit 55 will not be accidentally operated with the lid 58 open. Further, even if the operating section 55 is operated with the lid 58 opened, the detection means 69 detects the opening of the lid 58, and the control circuit
Since 72 stops energizing the electric motor 9, the stirring blade 11 does not rotate with the lid 58 open.

When the garbage is thrown in, the lid 58 is closed and the operating portion 55 is operated. In this state, the control circuit 72
Receives a signal from the detecting means 69 indicating the closure of the lid 58, operates the operating section 55 to rotate the electric motor 9 in the forward direction, and rotates the stirring blade 11 in the direction of the solid line arrow shown in FIG. Stirring blade 11
Rotates toward the V-shaped ridgeline side of the stirring blade 13, so that the kitchen waste and the processing medium 2 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 side, the kitchen waste located on the processing medium 2 is efficiently drawn into the processing medium 2 and is efficiently mixed with the processing medium 2 in a short period of time. Furthermore, since the stirring blades 13 are arranged in a spiral shape, the kitchen waste and the processing medium 2 are moved not only in the rotation direction but also in the axial direction to stir,
The stirring efficiency is further improved.

The control circuit 72 stops the operation when the electric motor 9 is normally rotated for 20 seconds in the present embodiment for a predetermined time, and after a predetermined time until the electric motor 9 is completely stopped, 5 seconds is elapsed in the present embodiment. After that, the electric motor 9 is rotated in the reverse direction, and the stirring blade 11 is rotated in the direction of the broken line arrow shown in FIG. Since the control circuit 72 reversely rotates the electric motor 9 after the electric motor 9 is completely stopped, the electric motor 9
The back electromotive force does not occur at the time of starting, and the durability of the electric motor 9 can be improved. When the electric motor 9 is in the reverse rotation state, the stirring blade 13 stirs the garbage and the processing medium 2 while pushing them to the outer periphery, and crushes the garbage with the side wall of the processing tank 1. This rotation direction has a larger load than the rotation in the normal rotation direction, but the crushing ability is improved.

The control circuit 72 reverses the electric motor 9 for a certain period of time, 20 seconds in this embodiment, and again causes the electric motor 9 to normally rotate again after the predetermined time until the electric motor 9 is completely stopped. The normal rotation and the reverse rotation are alternately repeated, and the operation is stopped when a total of 20 minutes has passed.

In the processing medium 2 of the processing section 3, microorganisms, especially nematodes, attached to the kitchen waste by discarding the kitchen waste in the processing tank 1,
Protozoa and bacteria propagate, and these microorganisms decompose garbage into water and carbon dioxide gas and extinguish it. Since the kitchen waste supplied to the processing tank 1 is crushed between the stirring blade 11 and the side wall of the processing tank 1, the kitchen waste decomposes and disappears in a relatively short time. Also, the processing medium 2
Since the temperature is maintained at a temperature at which the microorganisms are activated by the first and second heating means 21 and 26, the activity of the microorganisms is activated, and the decomposition and extinction efficiency of the garbage is further improved.

On the basis of the output of the second temperature sensor 71, the control circuit 72 causes the electric motor 9 to rotate forward every predetermined time when the outside air temperature becomes a predetermined temperature or less, or 10 degrees or less in this embodiment. The stirring blade 11 is rotated in the direction of the solid arrow shown in FIG. Since the rotating shaft 12 and the stirring blade 13 are made of a material having high heat conductivity, the heat of the first heating means 21 is applied to the stirring blade.
It is efficiently transmitted from 13 to the processing medium 2 and uniformly heats the processing medium 2 as the stirring blade 11 rotates. Also, the stirring blade 11
Is rotated in the direction of the solid line arrow shown in FIG. 5, the load applied to the processing tank 1 and the processing medium 2 is relatively small, and the processing tank 1
It is possible to suppress damage such as the above and miniaturization of the processing medium 2.

The water supplied to the treatment tank 1 together with the garbage is
The water generated by decomposing the kitchen waste passes through the purification unit 4 and is drained to the drainage unit 32. This water contains components that are produced in the process until the garbage is completely decomposed, that is, lower fatty acids such as acetic acid and propionic acid, sulfur compounds such as hydrogen sulfide and methyl sulfide, nitrogen compounds such as ammonia, and acetaldehyde. However, this component is purified by the purification unit 4
It is decomposed by microorganisms, especially bacteria, which propagate in the treatment medium 2, purified, and discharged to the drainage section 21.

As the stirring blade 11 rotates, the processing medium 2 is compressed and solidified by the stirring blade 13, and kitchen waste, especially kitchen waste containing a large amount of hardly decomposable components such as starch and gluten, exceeds the capacity for treating microorganisms. When discarded, the water permeability between the treatment section 3 and the purification section 4 on the outer periphery of the stirring blade 13 deteriorates,
Since water passages 31 are formed on both sides of the treatment tank 1 from the treatment unit 3 to the purification unit 4, the water in the treatment unit 3 flows through the water passages 31.
There is no adverse effect on the growth of microorganisms that are discharged to the purification unit 4 via the water and accumulated in the treatment unit 3 to be cultured in the treatment medium 2 of the treatment unit 3.

The water drained to the drain section 32 is drained from the drain hose through the drain port 36. If the partition plate 33 and the drainage port 36 that partition the drainage section 32 are clogged, remove the cap 35 from the drain tube 34 and insert a brush or the like into the drainage section 32 through the drain tube 34 to clean the partition plate 33. Then, clean the drain port 36.

Next, a second embodiment of the present invention will be described in detail with reference to FIGS. 13 and 14. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Reference numeral 76 denotes a substantially U-shaped square pipe arranged from the processing section 3 to the purification section 4, which is made of a material having corrosion resistance and high heat transfer property such as stainless steel, and is provided on a side surface with a large number of small pieces (not shown). A hole is bored and the internal space is used as a water passage 77 for draining the treatment section 3 to the purification section 4. The square pipe
Reference numeral 76 designates a reinforcing member 78, which is heat-transferably fixed to the pipe 28 of the second heating means 26 and is fixed to the side walls of the processing tank 1 in a direction substantially orthogonal to the rotating shaft 12 of the stirring blade 11 by a square shape. It is supported by penetrating the upper part of the pipe 76.

According to the second embodiment, the heat of the second heating means 26 is transferred by the square pipe 76, so that the processing medium 2 of the processing section 3 is heated more uniformly and the garbage is decomposed, as compared with the first embodiment. The processing efficiency is further improved. Further, the water passing through the water passage 77 is heated by the heat of the second heating means 26 transmitted through the square pipe 76, and is supplied to the purifying unit 3. Since the square pipe 76 is arranged between the stirring blades 13, the wastewater that passes through the water passage 77 and is supplied to the purifying unit 4 is supplied to the substantially central portion of the purifying unit 4. The entire treatment medium 2 can be effectively used for purification, and the entire purification unit 4 is heated to promote purification by microorganisms.

Further, since the square pipe 76 is disposed between the stirring blades 13, the garbage can be crushed between the square pipe 76 and the stirring blades 13, and the garbage can be crushed into smaller pieces to treat the garbage. The efficiency can be improved.
