Crush the kitchen waste with.

Numeral 38 is a net having a large number of slit-like holes 39 forming the conical surface of the dewatering spinner 36, and a frame 41 with a plurality of cut and raised pieces 40 protruding upward at the upper end, and a mounting plate 4 at the lower end.
2 are attached to each other.

43 is a waterproof ring attached to the lower part 16 of the main body in close proximity to the frame 41.

Reference numeral 45 denotes a dust box connected to the lower kitchen waste outlet 16c of the main body, and a removable lid 46 is installed at the upper end opening 45, and a buckle 47 provided at the upper end and a retaining portion provided at the bottom allow the upper and lower parts 13, 16 of the main body to be connected to each other. It is removable.

A fixed arm 44 is fixed to the main body cover part 13b and extends along the net 38 of the dewatering spinner 36 until its tip is close to the mounting plate 42, and is used to remove kitchen waste attached to the net surface of the dehydrating spinner 36. Raise it upward.

To explain the operation in the above configuration, the kitchen waste made in the sink is thrown into the crushing section 13a through the kitchen waste inlet 2 after opening the lid 5.

When the lid 5 is closed and the locking plate 6 is rotated by the lid knob 7, the magnet 9 attached to the locking plate 6 faces the reed switch 10, and at this time, the reed switch 10 senses the magnetic force of the magnet 9 and closes the contact. is turned on, and the motor 21 operates.

In the range where the reed switch 10 senses the magnetic force of the magnet 9, the locking plate 6 is hooked onto the protrusion 8, so that the lid cannot be opened.

As the motor 21 operates, a rotating plate 34, a rotating arm 35, and a dewatering spinner 36, which are fixed to a rotating shaft 29, rotate at high speed.

The kitchen waste in the crushing section 13a is pressed against the fixed blade 15 by the centrifugal force caused by the rotation of the rotary plate 34, and the kitchen waste is pressed against the fixed blade 15 and the rotary blade 37.
It is finely pulverized, passes through the fixed blade 15, and is blown to the net 38 of the spinner 36 for dewatering.

The kitchen waste containing a large amount of moisture is pressed against the net 38 of the dewatering spinner 36 that rotates at high speed, and is dehydrated through the hole 39, and is flipped up and raised up by the fixed arm 44, and the flipped up kitchen waste is pushed up by the rotating arm 35. The kitchen waste moves upwards due to the action of both sides.

At this time, the kitchen waste adhering to the outer circumferential wall of the main body upper cover part 13b is simultaneously scraped off by the rotating arm 35 which rotates close to the main body upper cover part 13b.

Further, kitchen waste dropped onto the mounting plate 42 of the spinner 36 for dewatering is scraped up again by the fixed arm 44.

The kitchen waste that has moved upward is removed from the kitchen waste discharge port 16 by the cut and raised piece 40.
c to the dust box 45 and stored in a plastic bag 51 attached to the dust box 45.

Although the water splashed out from the hole 39 of the dewatering spinner 36 hits the inner wall of the lower main body 16, the waterproof ring 43 prevents the water from flowing along the inner wall of the lower main body 16 and coming out from the kitchen waste outlet 16c.

In addition, the gear chamber 18 not only decelerates and transmits the rotation of the motor 21, but also makes the center of the motor 21 eccentric with respect to the rotating shaft 29, and buffers vibrations caused by balance fluctuations when kitchen waste is discharged from the kitchen waste discharge port 16c. There is.

Furthermore, the rotating arm 35 and the fixed arm 44 will be explained in detail.

The kitchen waste is dehydrated while being scattered on the inner surface of the dewatering spinner 36 by the rotating rake arm 35.
Since the dehydration chamber is prevented from adhering to the wall surface facing the spinner 36 for dehydration and is discharged upward, the dehydration chamber after the treatment is free from adhesion of kitchen waste and is always sanitary.

Furthermore, by tilting the rotary arm 35 in the raking direction, the resistance applied to the arm can be reduced, kitchen waste can be prevented from getting caught in the arm, and the garbage can be discharged more smoothly.

The distance between the rotating arm 35 and the wall is 1 to 37 ft.
Even if there is a gap of about 11 liters, the kitchen waste will get into the space and be discharged, so the wall surface will be cleaned as cleanly as if it had been wiped with a cloth.

Furthermore, if the inclination of the spinner for dewatering 36 is reduced and the fixed arm 44 is provided in a state that is close to or in contact with the inner wall surface of the spinner for dewatering 36, this fixed arm will scrape the kitchen waste adhering to the spinner for dewatering upward. Since it has an inclined surface to raise the surface, kitchen waste that is about to clog the hole of the dewatering spinner 36 is pulled away from the dewatering lug by the fixed arm 44 and thrown upward by the rotating arm 35, so that the dewatering spinner 36 is removed. The spinner 36 can be prevented from clogging, and the inside of the dehydration chamber can be automatically cleaned.

As described above, according to the present invention, a fixed arm having an inclined surface is provided close to or in contact with the inner circumferential surface of the spinner for dewatering, and a rotating arm is provided close to the outer circumferential wall surface of the crushing section, thereby eliminating a particularly complicated This has the remarkable effect of dehydrating and discharging kitchen waste while self-cleaning the dehydration chamber without using any special mechanism.

In addition, since the upward discharge of kitchen waste is carried out by a rotating arm, there is no need to increase the slope of the dewatering basket unlike in juicers, etc., and the dewatering basket can be nearly cylindrical, resulting in good dewatering efficiency and product retention. It is possible to create a compact kitchen waste processor that can be made smaller in the radial direction and easily installed on a sink.
