Interfering temperature, in this example, about 35 to 60 degrees
It is designed to be maintained every time.

Reference numeral 11 denotes a drainage section defined by a metal partition plate 12 having a large number of small holes so that the processing medium 2 does not leak below the processing tank 1. It is designed to connect and drain into a septic tank or sewage.

Reference numeral 14 denotes a cylindrical metal side wall plate which covers the outer periphery of the processing tank 1, and is fixed to the outdoor side of the wall surface of the house by a fitting not shown. Reference numeral 15 denotes a synthetic resin top plate that is placed and fixed on the side wall plate 14, and is formed adjacent to the substrate storage chamber 16 and the substrate storage chamber 16 that are watertightly partitioned from the inside and outside of the processing tank 1. It has an exhaust chamber 17 that connects the inside and the outside of the tank 1. Reference numeral 18 denotes a blower mounted below the exhaust chamber 17, which is disposed in the processing tank 1 through a waste disposal port 20 described later and a disposal duct 19.
The air sucked inside is exhausted to the outside via the exhaust chamber 17.

One end 19 passes through the top plate 15 and the processing tank 1
The other end is a waste duct that penetrates the wall surface of the house and opens above the sink of the kitchen, and the indoor side opening of the other end serves as a garbage disposal port 20. The waste duct 19 is formed of a low friction resistance material such as olefin resin or high density polyethylene resin, or is formed by coating a low friction resistance material such as Teflon on the inner surface of the duct formed of resin or metal. .

Reference numeral 21 denotes a lid body which is pivotally supported on the wall surface of the house so as to open and close the garbage disposal port 20 of the disposal duct 19. Reference numeral 22 denotes a detection switch mounted on the waste duct 19 for detecting the open / closed state of the garbage disposal port 20 of the lid body 21, stopping the power supply to the electric motor 8 when the lid body 21 is open, and the lid body 21 serves as a kitchen waste. When the waste port 20 is opened and closed again, the electric motor 8 is driven to mix the kitchen waste discarded from the kitchen waste port 20 into the processing tank 1 with the processing medium 2.

The kitchen waste produced by cooking is covered with the lid 21.
Is opened and discarded from the garbage waste port 20 to the treatment tank 1 through the waste duct 19, and water is poured to wash away the garbage attached to the inner surface of the waste duct 19 into the treatment tank 1. Since the waste duct 19 is formed of a low friction resistance material or is coated with a low friction resistance material, the garbage is smoothly disposed of in the treatment tank 1, and the garbage adheres to the inner surface of the waste duct 19 so that the waste duct 19 The kitchen refuses to rot. In addition, even if the kitchen waste is decomposed in the waste duct 19, the blower 18 sucks air through the waste duct 19, so that the rotten smell does not leak to the kitchen and gives the user discomfort. There is no such thing.

When the garbage is put in, the lid 21 is closed. The detection switch 22 detects that the lid 21 is closed, and the electric motor 8
Rotates in the forward direction to rotate the stirring blade 3 in the direction of the solid arrow shown in FIG. Since the stirring blade 3 rotates toward the V-shaped ridgeline side of the stirring blade 5, 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 5 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. further,
Since the stirring blades 5 are arranged in a spiral shape, the kitchen waste and the processing medium 2 are moved not only in the rotational direction but also in the axial direction to stir, and the stirring efficiency is further improved.

When the electric motor 8 is normally rotated for 20 seconds in this embodiment, the operation is stopped, and after a predetermined time until the electric motor 8 is completely stopped, in this embodiment, the electric motor 8 is rotated in the reverse direction after 3 seconds and agitated. The blade 3 is rotated in the direction of the broken line arrow shown in FIG.
Since the electric motor 8 stops completely and then reverses, no back electromotive force is generated when the electric motor 8 is started, and the durability of the electric motor 8 is improved. In the reverse rotation state of the electric motor 8, the stirring blade 5 stirs the garbage and the treatment medium 2 while pushing them to the outer periphery, and crushes the garbage with the side wall of the treatment tank 1. This rotation direction has a larger load than the rotation in the normal rotation direction, but the crushing ability is improved.

When the electric motor 8 is reversely rotated for a certain period of time, that is, 20 seconds in this embodiment, the electric motor 8 is normally rotated again after a predetermined time until the motor 8 is completely stopped. The normal rotation and the reverse rotation are alternately repeated, and the operation is stopped when a total of 20 minutes have passed.

The kitchen waste mixed with the treatment medium 2 is decomposed into water and carbon dioxide by the bacteria and microorganisms cultured in the treatment medium 2 and disappears. The kitchen waste discarded in the processing tank 1 has a stirring blade 3
And the side wall of the processing tank 1 are crushed, so that they decompose and disappear in a relatively short time. Moreover, since the treatment medium 2 is maintained at the temperature at which the bacteria and microorganisms are activated by the heating means 10, the efficiency of the garbage treatment is further improved.

FIG. 5 and FIG. 6 show a second embodiment of the present invention, in which a sprinkling pipe 23 having a large number of sprinkling holes is disposed on the garbage disposal port 20 side of the waste duct 19. 24 is an electromagnetic valve that controls the supply of water to the sprinkling pipe 23.When the detection switch 22 detects that the lid 21 has opened the garbage disposal port 20 and closed it again, the sprinkling pipe 22 is filled with water after a predetermined time. Sprinkle and discard duct 19
The garbage attached to the inner wall is washed off into the processing tank 1. The electromagnetic valve 24 supplies water to the sprinkler pipe 23 a predetermined time after the lid 21 closes the kitchen waste disposal port 20, so that the user needs to dispose of the lid 21 in order to discard the kitchen waste generated by one cooking. Even when the lid 21 is opened and closed again, the waste duct 19 is not sprayed every time the lid 21 is opened and closed, and the water is not wasted.

In the first and second embodiments, the waste of the kitchen waste is detected by opening and closing the lid 21, but as in the third embodiment shown in FIGS. 7 and 8, the light emitting element 25 and the light receiving element 26 are used.
Even if it is configured to control the electric motor 8 and the electromagnetic valve 24 by providing an optical sensor consisting of, the garbage is detected by the change in the amount of light received by the light receiving element 26 when the garbage passes between the light emitting element 25 and the light receiving element 26. Good. In the third embodiment, the waste duct 19 is provided with a plurality of optical sensors to surely detect the garbage passing through the waste duct 19. Further, the light emitting element 25 and the light receiving element 26 receive and emit light through the light transmitting member 27 that is watertightly mounted in the opening formed in the waste duct 19, and the water sprayed from the water spray pipe 23 to the waste duct 19 and the like. This prevents the light emitting element 25 and the light receiving element 26 from being damaged.

9 and 10 show a fourth embodiment, in which 28 is a shutter swingably mounted at the opening of the disposal duct 19 on the side of the processing tank 1, and the spring 29 constantly closes the disposal duct 19. The shutter 28 is made of a low friction resistance material such as an olefin resin or a high-density polyethylene resin, or a plate-shaped member made of a resin or a metal, in order to prevent garbage from adhering to the shutter 28. It is formed by coating the surface of a low friction resistance material such as Teflon. The spring 29 is set to an urging force such that when the garbage is dumped on the shutter 28, the shutter 28 is easily opened by the weight of the garbage.

Reference numeral 30 denotes a reed switch mounted on the top plate 15, which detects the opening / closing of the shutter 28 by the magnetic force of a magnet 31 fixed to the shutter 28 and controls the electric motor 8 and the solenoid valve 24.
