Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kitchen waste processing device that is connected to a drain outlet of a sink, etc., and prevents fibrous kitchen waste generated during dehydration and discharge after crushing from getting caught on a fixed arm and being separated. , the purpose is to maintain a normal discharge state at all times.

Conventionally, as a kitchen waste processing device, the kitchen waste inputted from the drain of the sink is crushed by a fixed blade and a rotating blade, and the crushed kitchen waste is separated from water by a dewatering spinner whose peripheral wall is in the shape of an inverted truncated cone. A device has been proposed in which 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 main body.

In the above-mentioned kitchen waste processing apparatus, among the thrown-in kitchen waste, fibrous waste is crushed and discharged into the dewatering spinner in the form of streaks.

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. If kitchen waste accumulates one after another in this state, the kitchen waste caught on the fixed arm will rub against the inner circumferential surface of the dewatering spinner, and eventually the sliding resistance will increase and the motor may stop. Furthermore, if the sliding resistance becomes large, the rotation becomes strained, which not only causes thermal deformation and fire due to abnormal heat generation of the motor, but also deformation and destruction of the fixed arm. If the device becomes unusable in this way, after removing it from the sink,
This device must be disassembled, the inside cleaned, and reassembled, which requires a great deal of effort and time. The present invention solves the above-mentioned drawbacks, and embodiments 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 composed of a cylindrical body 2a, and also serves as a kitchen waste input port. A lid 3 is detachably attached to 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 consists of a bottomless cylindrical portion 5a and a cover portion 5b that extends outward and upward from the open bottom end of the cylindrical portion 5a. 6 is the upper body 5
It is a fixed blade provided at the lower end of the cylindrical portion 5a, 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 kitchen waste outlet 7c is provided in a part of the upper end of the lower body 7.
8 is a gear mechanism installed on the bottom plate 7a of the lower body 7 to reduce 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. At its end, there is a rotary plate i provided at the lower end of the fixed blade 6 of the cylindrical portion 5a of the upper body 5, and a rotary arm 12 provided close to the outer peripheral surface of the cover part 5b of the upper body 5. , and an inverted truncated cone-shaped dewatering spinner turtle 3 that covers the rotating arm turtle 2 are integrally fixed. The ears 4 are a pair of left and right rotary blades 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 blade 14 and the fixed blade 6 constitute a crushing mechanism 38. The peripheral wall turtle 5 of the dewatering spinner A3 is composed of a silk-like body formed by providing a large number of slit wings 6 on a plate body. A frame 1 fin having a plurality of cut and raised pieces 17 projecting upward is fixed to the upper end of the peripheral wall turtle 5. The oven 9 is the bottom wall of the dewatering spinner 13. 20' is a fixed arm disposed close to the inner surface of the peripheral wall 15 of the dewatering spinner 13, and its lower end faces the bottom wall 195 of the dewatering spinner 13.

2 is a dust box that is removably attached to the lower body, and is transported to the kitchen waste outlet 7c of the lower body 7 through the kitchen waste storage opening 21a.

Is there a lower body in the dust box 21? A removably attached plastic bag 22 is stored in the kitchen waste outlet 7c.
2 to 6 show the mounting structure of the fixed arm 20. FIG.

The upper end of the fixed arm 20 is inserted between the through hole 23 of the upper body 5 and a pair of IJ ribs 25 and 26 protruding from the upper surface of the upper body 6. A fixed arm 20G is supported by a pin 24 so as to be rotatable back and forth in the rotational direction of the dewatering spinner turtle 3 (in the direction of arrow EOB in FIG. 4). arc piece 20 close to
a, 25a are provided with the axis of the pin 24 as the center of the circular arc. The arc piece 20a of the fixed arm 20 is provided with a U-shaped notch hole 40, and the arc piece 25a of the lip 25 is provided with a hole 41. The notch hole 40 is provided with the intermediate portion 40a along the rotating direction of the fixed arm 20, and the long hole 4M is provided so as to coincide with the pair of parallel portions 40b and 40c of the notch hole 40. The fixing pin 29 is engaged across the parallel portions 48b, 40c of either one and the elongated hole 41, and a tension 1 imitation 42 is interposed between the hook portion 29a provided on the fixing pin 29 and the outer surface of the main body 5. During normal use, the fixing pin 29 is inserted into the parallel portion 40b at the rear of the rotation direction B of the dehydration spinner turtle 3, and
As shown in FIG. 4, rotation is prevented by a fixing pin 291 at an angle having an inclination angle (Q) with respect to the rotation direction B. A fixing mechanism 31 for the fixing arm 20 is constituted by the fixing pin 29, the four notched holes 41, and the tension spring 42. Next, the operation of the above-mentioned L will be explained.

The kitchen waste thrown in from the drain 2 of the water tank i is crushed by the fixed blade 6 and the rotary 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 turtle 5 due to centrifugal force, but is scraped off from the fixed arm 20' and is further flipped up by the rotating arm 12. It is discharged to the dust box 21. When used for a long period of time in this way, fibrous kitchen waste gets caught on the fixed arm 2Q' and is trapped between it and the dewatering spinner 13, preventing the kitchen waste from being discharged into the dust box 21. The fixing pin 29 fixing the fixing pin 28 is inserted into the other parallel part 4Qc of the notch hole 40.
As shown in FIG.
8) By making the fixed arm 20 loose, the kitchen waste adhering to the fixed arm 20 is smoothly scraped upward and easily discharged from the kitchen waste discharge port to the dust box 2 outside the vessel.
When the accumulation of kitchen waste on the fixed arm 28 is eliminated,
The fixed arm 20 is used with its inclination angle returned to (Q). The rotation operation of the fixed arm 20 is performed by the fixing mechanism 3 as in this embodiment.
1 on the outside of the main body 5, it can be easily carried out from the outside of the main body 5 without disassembling the device.
In this manner, the accumulation of fibrous kitchen waste can be easily eliminated by rotating the fixed arm 20. Therefore, the fixed arm 2Q can be periodically rotated to maintain the normal discharge of kitchen waste at all times, and an excessive load is not applied to the drive motor, preventing thermal deformation or ignition due to abnormal temperature rise. The danger of As explained above, according to the present invention, since the fixing arm is rotatably supported and the fixing mechanism is provided to fix the fixing arm so as to be able to change the angle, fibrous kitchen waste caught on the fixing arm can be removed. Accumulation can be easily eliminated by rotating the fixed arm, so normal discharge of kitchen waste can be maintained at all times.
