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 products that are dehydrated after being crushed, this prevents water and dirt from flowing out of the drainage holes into the sewer through the slits of the dehydrating spinner, and improves the ability to crush kitchen waste.

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 crushing, and the water will be separated using a dewatering spinner. In this case, water and dirt flow through the slits and drain into the sewer through the drain hole, which has the disadvantage of exceeding the sewage treatment capacity. As shown in Fig. 1, a fixed blade with 10 cutouts 100a has been considered, but with this, even if a fork or the like is driven in a depressed position, it will pop out from the notches 100a and have a negative impact on other parts. It is necessary to have a dimension that does not give any damage to the silk surface of the dehydrating spinner (without damaging the silk surface of the dehydrating spinner), and the dimension A needs to be about 6 sides. When pulverized in this state, the pulverization size Y is very small compared to the kitchen waste size This has the disadvantage that it also flows out into the sewage system, which exceeds the sewage treatment capacity. The present invention is intended to eliminate the drawbacks of the above-mentioned secondary structure, and one embodiment thereof will be described below with reference to FIGS. 2 to 4.

Reference numeral 44 denotes a fixed arm that is in contact with the inner surface of the silk 38 of the dewatering spinner 36 or is fixed to the main body 13 with a slight gap, and its lower end is attached to the mounting plate 42 of the dehydrating spinner 36. .

45 is a kitchen waste storage port 45a in the main body bottom kitchen waste discharge port 16c.
The dust box is connected to
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 upper iso configuration, the kitchen waste made in the sink is thrown into the upper cylindrical part 13a of the main body through the 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 provides assistance. The light turns ON and the motor 21 starts operating. 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,
It is finely pulverized by the blade portion 15b of the fixed blade 15 and the rotary blade 37, passes through the fixed blade notch 15a, and is blown onto the silk 38 of the dewatering spinner 36. The kitchen waste containing a large amount of water is pressed against the silk 38 of the dewatering spinner 36 that rotates at high speed, and is dehydrated by the slit 39, and then transferred to the fixed arm 44.
The kitchen waste moves upward by both the turning up and rising by the rotating arm 35 and the flipping up of the turned up kitchen waste by the rotary arm 35. 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, the kitchen waste dropped onto the mounting plate 42 of the dewatering spinner 36 is picked up again by the fixed arm 44. The kitchen waste that has moved upward is ejected from the cut and raised piece 401 through the kitchen waste outlet 16c to the dust box 45, and is 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.
This buffers 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. dust box 45
The kitchen waste storage opening 45a enters into the kitchen waste discharge port 16c so as to receive the bottom surface of the frame 41 of the dewatering spinner 36, so when the dust box 45 is removed, the waterproof ring 4
The dirty juice remaining on the body 3 is reduced to the inner wall side of the lower body 16 and does not flow out to the exterior of the lower body 16. The dust box packing 52 holds a plastic bag 51, etc., in an airtight manner by pressing it onto the garbage discharge port 16c, and the plastic bag 51, etc. is held by a rotary blade 37, a rotary arm 35, and a dewatering spinner 36 at the same time as the equipment is operated. It spreads all over the inner wall of the dust box 45 in response to the pressure storm sent from the kitchen waste outlet 16c. Further, the dust box 45 and the lid 47 are arranged so that the plastic bag 51 and the like open immediately upon receiving the pressure air.
It has a gap through which the air can escape. Here, to explain in more detail the function of the fixed blade 15, which is the gist of the present invention, as shown in FIGS. 3 and 4, the fixed blade 15
A blade portion 15b protrudes from the inner peripheral surface of the adjacent blade portion 1.
5b is larger than the inside of the notch 15a.

For this reason, 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 notch 15
While maintaining the same dimension as in Fig. 1, with A in the middle of a being 6 skin, the crushing dimension Y' is larger than Y in Fig. 1 with respect to the kitchen waste dimension x, and the blade part 15b is on the inner periphery. Because of the protrusion, a step layer is formed between the rotary blade 37 and the fixed blade 15, and 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.
