Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kitchen waste disposal machine that hygienically crushes and dehydrates kitchen waste generated in a home kitchen, and particularly relates to a self-cleaning structure of a centrifugal dewatering mechanism.

Conventionally, centrifugal dehydration is the most reliable method for crushing and dehydrating vegetable waste such as kitchen waste, and it is the easiest method to commercialize, so various kitchen waste processing machines have been considered, but for general household use A practical product that is inexpensive and requires no maintenance has not yet been developed.

This is because no inexpensive structure has been developed to continuously self-clean the clogging of the centrifugal dehydrator's filter and kitchen waste adhering to the walls of the dehydration chamber, resulting in the dehydrator becoming clogged and no longer dehydrating. The food waste adhering to the dehydration chamber has problems such as rotting and producing odor, and cannot be turned into a product.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a connecting rubber that is airtightly attached to a water tank 2 of a sink by a bolt 4 provided at an inlet 3. The lower end of this connecting rubber 1 is fitted with an upper case 5, and a tightening band 6 It is attached by.

Reference numeral 7 denotes a fixed blade located on the right side of a notch attached to the cylindrical lower end of the upper case 50, and a crushing chamber 5a is formed inside the upper case 5 including the fixed blade 7.

Reference numeral 8 denotes a lower case of the kitchen waste processing device attached to the lower part of the upper case 5, which is divided into a separation chamber 9 and a gear chamber 10 by partition walls 8a and 8b. It is a provision.

Reference numeral 12 designates a motor provided in the motor chamber 13 of the upper case 8, and its motor shaft 14 extends through the partition walls 8a and 8b and faces the separation chamber 9.

Reference numeral 15 denotes a rotary plate fixed to the tip of the motor shaft 14, and is provided close to the inner wall of the fixed blade 7.

On its upper surface is a rotary blade 16 that faces the inner surface of the fixed blade 7.
There is a pair on the left and right.

17 is a conical dehydration spinner disposed in the separation chamber 9 so as to cover the outer periphery of the fixed blade 7, and has a number of holes 18 in its conical surface.
have.

This dewatering spinner 17 has a spinner shaft 19 attached to its bottom surface that is loosely inserted into the motor shaft 14 so that it can rotate freely, and a gear 20 is fixed to the lower end portion facing the gear chamber 10.

This gear 20 is a speed increasing gear 2 provided in the gear chamber 10.
1 to a drive gear 22 fixed to the motor shaft 14 so that it rotates a little faster than the one-rotation plate 15.

Reference numeral 23 denotes a waste removal arm disposed close to the inner surface of the dewatering spinner 17, which is attached to the one-rotation plate 15.

Reference numeral 24 denotes a garbage discharge port opened at the joint between the upper case 5 and the lower case 8, and 25 denotes a dust box connected to the garbage discharge port 24, which can be attached to and detached from the lower case 8 with a handle 26 and a buckle 27.

28 is a plastic bag provided inside the dust box 25.

The waste removal arm 23 is connected to the dewatering spinner 17 as described above.
It is formed so as to be close to or in contact with the inner surface of the crushing chamber 5a, and also to be close to the outer peripheral wall surface of the upper case 5 so as to scrape off kitchen waste adhering to the outer wall surface of the upper case 5.

The waste removal arm 23 is made of a hard, elastic material such as metal, and there is a large gap between it and the dewatering spinner 17 in a stationary state.

The rotating plate 15 is deformed by the centrifugal force of the waste removal arm 23 as the rotary plate 15 rotates, and the position where the elastic restoring force is balanced is exactly in contact with or very close to the inner circumferential surface of the dewatering spinner 17.

Further, the part of the waste disposal arm 23 that the kitchen waste touches is inclined with respect to the radiation line along the inner circumferential surface of the dewatering spinner 17.

It is configured to scrape up kitchen waste adhering to the dewatering spinner 17.

As shown in detail in FIG. 3, 23a is a spatula part fixed to the waste removal arm 23, which is provided perpendicularly to the inner circumferential surface of the dewatering spinner 17, and as shown in FIG. On the other hand, one is configured to scrape off kitchen waste from below the dewatering spinner 17, and the other from above.

In the above configuration, when the motor 12 is rotated.

As the rotary plate 15 fixed to the motor shaft 14 rotates, the dehydrator 17 rotates at high speed via the gear group 20, 21, 22.

The kitchen waste accumulated in the upper case 5 that constitutes the crushing chamber is 1
The centrifugal force of the rotary plate 15 causes it to be thrown toward the fixed blade 7, and the rotary blade 16 and the fixed blade 7 crush it.

And this crushed kitchen waste. It scatters from the notch of the fixed blade 7 into the dewatering spinner 17, where it is centrifugally dehydrated.

This centrifugally dewatered kitchen waste is pushed upward by the upward component force generated in the conical portion of the dewatering spinner 17 and the waste removal arm 23, and is flicked off from the upper opening edge of the dewatering spinner 17 and sent from the kitchen waste discharge port 24 to the dust box 25. is automatically discharged into a plastic bag 28.

And a dewatering spinner 17 and a waste removal arm 2 with different rotation speeds.
3 is rotated between an appropriate gap between the dehydration spinner 17 and the wall of the dehydration chamber, the kitchen waste scattered within the dehydration spinner is discharged upward while rubbing against the dehydration spinner and the wall of the dehydration chamber. The dewatering spinner 17 does not become clogged, and the dehydrating chamber can be automatically and continuously cleaned without any kitchen waste adhering to the wall surface.

Also, if you change the inclination of the dewatering spinner to a cylindrical angle from 30° instead of making it as large as in a juicer (37°), the kitchen waste blown away by the dehydrating spinner will be reduced.

This is because the layer is instantly damaged and becomes several meters thick.

The waste removal arm 23 and the dewatering spinner 17 are separated by 1 m without contacting each other.
Even if there is a gap of about 2 m/m to 2 m/m, the kitchen waste works by scraping the kitchen waste and scraping it up, so that reliable leaning can be achieved.

Moreover, by not bringing the dewatering spinner and the waste removal arm into contact with each other, it is possible to reduce noise and prevent wear of the waste removal arm.

In this way, according to the present invention, while crushing and dehydrating kitchen waste,
Since it can be processed hygienically, it is possible to prevent spoilage and the like, thereby realizing a kitchen waste processing device that can be used in general households.
