Description

[Detailed description of the invention] The present invention relates to a kitchen waste processing device connected to a sink drain, etc., and prevents fibrous kitchen waste generated during dehydration and discharge after crushing from getting caught in the fixed arm, so that normal operation is always maintained. The purpose is to maintain the discharge state.

Conventionally, kitchen waste processing equipment uses fixed blades and rotating blades to crush the kitchen waste that is put in through the drain of the sink, and then separates the crushed kitchen waste from water using a dewatering spinner with an inverted truncated cone shape whose peripheral wall is made of a net. However, it has been proposed that the kitchen waste separated and attached to the screen is scraped off by a fixed arm, and further scraped up by a rotating arm and discharged into a dust box outside the vessel.

In the above-described kitchen waste processing apparatus, among the input kitchen waste, fibrous waste is crushed into a sushi-like shape and discharged to the dewatering spinner.

When this fibrous kitchen waste is dehydrated and scraped upward,
It gets caught between the fixed arm and the dewatering spinner and straddles the fixed arm.

As kitchen waste accumulates one after another in this state, the kitchen waste caught on the fixed arm rubs against the inner peripheral surface of the dewatering spinner.
Eventually, a remoter with large sliding resistance may be stopped.

Also, if the sliding resistance increases, rotation will be forced, and
Abnormal heat generation in the motor not only causes thermal deformation and fire, but also may cause deformation and destruction of the fixed arm.

The present invention is intended to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

1 is the water tank of the sink, and 2 is the drain port of the water tank 1.

The drain port 2 is made of a cylindrical body 2a, and also serves as a kitchen waste inlet.

A lid 3 for opening and closing the drain port 2 is detachably mounted inside the upper end of the cylinder 2a.

A connecting tube 4 made of anti-vibration rubber is attached to the lower part of the cylinder 2a, and an upper main body 5 of the kitchen waste processing device is attached below the connecting tube 4.

The upper body 5 includes a bottomless cylindrical portion 5a and a cover portion 5b that extends outward and upward from the lower opening edge of the cylindrical portion 5a.

A fixed blade 6 is provided on the cylindrical portion 5a and the lower end of the upper body 5, and has notches 6a at appropriate intervals in the circumferential direction.

A lower body 7 is attached to the lower part of the upper body 5, and has a bottom plate 7a near the bottom.

A drainage hole 7b connected to a sewer pipe is provided in the bottom plate 7a, and a garbage discharge lower C is provided in a part of the upper end of the lower body 7.

Reference numeral 8 denotes a gear mechanism installed on the bottom plate 7a of the lower body 7, which decelerates the rotation of the motor 9.

The rotation of the motor 9 is transmitted to the rotating shaft 10 via the gear mechanism 8.

The rotating shaft 10 protrudes from the bottom plate 7a of the lower body 7, and at its end there is a rotary plate 11 provided so as to be located at the lower end of the fixed blade 6 of the cylindrical part 5a of the upper body 5, and a cover of the upper body 5. Part 5b
A rotary arm 12 provided close to the outer peripheral surface and a dewatering spinner 13 in the shape of an inverted truncated cone that covers the rotary arm 12 are integrally fixed.

Reference numeral 14 denotes a pair of rotary blades on the left, which are disposed on the upper surface of the rotary plate 11 so as to face the inner surface of the fixed blade 6, and the rotary force 14 and the fixed blade 6 constitute a crushing mechanism 30.

The peripheral wall 15 of the dewatering spinner 13 has a large number of sulins 1 on a plate.
It is composed of a net-like body in which 16 are provided.

19 is the bottom wall of the dewatering spinner 13.

A frame 18 with a plurality of raised pieces 17 projecting upward is fixed to the upper end of the peripheral wall 15, and a mounting plate 19 is fixed to the lower end.

A fixed arm 20 is attached to the upper body 5 in close proximity to the inner surface of the net 15 of the dehydration spinner 13, and its lower end faces the bottom wall 19 of the dehydration spinner 13.

21 is a kitchen waste storage opening 21a in the kitchen waste discharge lower C of the lower body 7.
A plastic bag 22 is attached to the inside of the dust box, which is detachably attached to the garbage discharge lower C of the lower body 7 through the garbage storage opening 21a.

A plurality of protrusions 15 are provided on the inner surface of the peripheral wall 15 of the dewatering spinner 13.
A is provided at the height of the gap with the fixed arm 20.

The protrusion 15a is a part of the peripheral wall 15, formed in the shape of a rib with an elliptical planar shape, and is inclined at a rear end with respect to the direction of rotation of the dewatering spinner 13 (direction of arrow a). .

The projections 15a are arranged so that substantially the entire surface of the fixed arm 20 in the longitudinal direction corresponds to one of the projections 15a.

The protrusions 15a are arranged at equal intervals in the circumferential direction and the height direction of the peripheral wall 15.

Next, the operation of the above configuration will be explained.

Kitchen waste thrown in from the drain port 2 of the water tank 1 is crushed by the fixed blade 6 and the rotating blade 14, and is discharged from the notch 6a of the fixed blade 6 to the inner surface of the peripheral wall 15 of the dewatering spinner 13 by centrifugal force.

The discharged kitchen waste adheres to the peripheral wall 5 due to centrifugal force, but is scraped off by the fixed arm 20 attached to the upper body 5 and close to the peripheral wall 15, and then thrown off by the rotating arm 12. The waste is discharged from the waste discharge lower C to the dust box 21 outside the vessel using the cut and raised piece 17 at the upper end of the dewatering spinner 13.

The above explanation is for general kitchen waste, but in the case of fibrous kitchen waste, it becomes sushi-shaped after being crushed and is discharged onto the inner surface of the peripheral wall 15 of the dewatering spinner 13, and further between the fixed arm 20 and the peripheral wall 15. and gets caught in such a way as to straddle the fixed arm 20.

In this way, fibrous kitchen waste is deposited on the fixed arm 20.

At this time, a protrusion 15a is attached to the peripheral wall 15 of the dewatering spinner 13 at a height of a gap with the fixed arm 20, and this protrusion 15a scrapes the accumulated fibrous kitchen waste on the fixed arm 20. Scrape it off, so it's always free of snags.

Although it is effective even if the projection 15a is simply conical in shape, if the projection 15a is formed into a rib shape and is inclined as in this embodiment, the food waste caught on the fixed arm 20 will be thrown upward. Since it is pushed out, even higher effects can be obtained.

As explained above, according to the present invention, it is possible to eliminate the problem of fibrous kitchen waste getting caught in the fixing arm, which was a drawback of the conventional method, and there is no malfunction such as motor lock or breakage of the fixing arm. can maintain proper use.
