Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kitchen waste processing device that hygienically processes kitchen waste from home kitchens, etc., and its purpose is to prevent kitchen waste from turning into sludge when crushed. In the case of crushing and dewatering, this prevents water from the dewatering spinner's Surin+ from turning into sewage and flowing out into the sewer through the drain hole.

Conventional disposers dispose of crushed kitchen waste along with water into the sewage system, which puts a burden on sewage treatment, and their use is now prohibited.

Various attempts have also been made to develop equipment for crushing and dehydrating kitchen waste, but if the crushing mechanism uses the same hammer mill method as the disposer, the kitchen waste will be ground up and turned into sludge during the crushing process. In this case, the problem is that water and dirt flow through the slits and flow out into the sewer through the drain hole, which exceeds the sewage treatment capacity.

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

45 is a kitchen waste storage port 45a in the main body bottom kitchen waste discharge port 16c.
The garbage storage opening 45a has a dust box backing 52, and the upper end opening 4
A removable lid 47 is attached to 6, and a buckle 48 is provided at the upper end.
It can be attached to and detached from the upper and lower parts of the main body 13 and 16 by means of an engaging part provided on the bottom surface.

49 is a second magnet attached to the dust box 45, 50
is a second reed switch disposed below the main body 16 with respect to the magnet 49.

Reference numeral 51 denotes a plastic bag that is detachably attached to the main body waste outlet 16c through the kitchen waste storage opening 45a of the dust box 45.

To explain the operation in the above configuration, kitchen waste made in the sink is thrown into the upper cylindrical part 13a of the main body through the charging opening 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. turns 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 upper cylindrical part 13a of the main body is pressed against the fixed blade 15 by the centrifugal force caused by the rotation of the rotary plate 34, is finely pulverized by the blade part 15b of the fixed blade 15 and the rotary blade 37, and passes through the fixed blade notch 15a. The water is then 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 rotating at high speed, is dehydrated by the slit 39, and is flipped up by the fixed arm 44 and raised up. The kitchen waste moves upwards due to the action of both being thrown up.

At this time, the kitchen waste adhering to the main body upper cover part 13b is 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 or the like installed in the dust box 45.

The water that jumps out from the slit 39 of the dewatering spinner 36 hits the inner wall of the lower main body 16, but 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, since a recess 16d is formed in a part of the circumference of the inner wall of the lower main body 16, water does not rotate together between the dehydration spinner 36 and the lower main body 16 during operation, and the water is formed in a layered manner. It is guided to the drainage hole 16b without being drained.

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 to the rotating shaft 29 to buffer vibrations caused by balance fluctuations when kitchen waste is discharged from the kitchen waste discharge port 16C. .

Since the reed switch 50 senses the magnetic force of the magnet 49 attached to the dust box 45 and turns on, the equipment cannot be operated unless the dust box 45 is installed.

The kitchen waste storage opening 45a of the dust box 45 is arranged so that the kitchen waste discharge port 16 receives the lower surface of the frame 41 of the dehydration spinner 36.
c, the dirt remaining on the waterproof ring 43 when the dust box 45 is removed falls into the inner wall side of the lower body 16 and does not flow out onto the exterior of the lower body 16.

The dust box backing 52 holds a plastic bag 51 or the like airtightly by pressing it onto the garbage outlet 16c.
The first class spreads all over the inner wall of the dust box 45 by receiving pressurized air sent from the kitchen waste outlet 16c by the rotary blade 37, the rotary arm 35, and the dewatering spinner 36 at the same time as the equipment is operated.

Further, the dust box 45 and the lid 47 have a gap through which the air inside the dust box 45 can escape so that the plastic bag 51 etc. can open immediately upon receiving the pressure air.

Here, the structure Q function of the fixed blade 15, which is the gist of the present invention, will be explained in more detail.As shown in FIG. 2, the fixed blade 15 has comb-shaped inner and outer blades 15'.

The inner and outer cutters are 15'.

The cutout portion 15a and the step-layered blade portion 15b are formed by a circumferential offset of 15".

Therefore, the kitchen waste pressed against the inner surface of the fixed blade 15 becomes stuck in the step layer between the blade part 15b and the cutout part 15a, and is crushed by the rotary blade 37 and the blade part 15b of the fixed blade 15.

In crushing in this state, the rotary blade 37 and the fixed blade 1
A layer is formed between the two and the kitchen waste is not ground up and turned into sludge.

Therefore, the amount of sewage flowing out together with water from the slits of the dewatering spinner can be reduced and kept below the sewage treatment capacity.

Moreover, the ability of kitchen waste to bite into the blade portion 15b of the fixed blade 15 is improved, and the processing time can be shortened.

As described above, by considering the configuration of the fixed blade, the kitchen waste processing device of the present invention solves the problem of kitchen waste being ground into sludge, and the kitchen waste can be easily bitten into the blade part for crushing. This has an excellent effect of reducing time.

Furthermore, by dividing the fixed blade into an inner blade and an outer blade, the fixed blade can be manufactured using a press, etc. This makes mass production easier, reducing manufacturing costs, and reducing costs with hard sevens. It is also possible to use expensive materials for the inner blades necessary for crushing, and for the outer blades to be made of inexpensive materials, further reducing costs.
