Abstract

PURPOSE: To make it possible to surely remove the sheet-like garbage tightly sticking to the inside surface of the peripheral wall of the strainer of a garbage treating device at the time of dehydration. CONSTITUTION: The strainer 15 is supported movably at high speed around the axial line of the cylindrical peripheral wall 15b of a motor. The strainer 15 is provided with a friction plate 40 in a direction orthogonal with the peripheral direction of the cylindrical peripheral wall 15b made of stainless steel. The friction plate 40 is formed of a plate material larger in the coefft of friction of its inside surface 40a than that of the inside surface 15c of the peripheral wall. If the sheet-like garbage is held between the inside surface 15c of the peripheral wall and the blade pressed thereto during the dehydration, the friction force induced therebetween at every contact of the sheet-like garbage with the friction plate 40 grows to the force larger than the friction force generated when the garbage comes into contact with the inside surface 15c of the peripheral wall exclusive of the friction plate 40 and consequently, the force to co- rotate the sheet-like garbage by rotation of the strainer 15 changes repetitively to the strong or weak force, by which the garbage is dislodged from between the blade and the inside surface 15c of the peripheral wall.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, for example, is installed in a sink connected to a drain pipe of a sink to dehydrate kitchen waste such as garbage discharged from the drain pipe together with water, and to remove water and kitchen waste after dehydration. The present invention relates to a garbage disposal device for separation processing.

[0002]

2. Description of the Related Art Conventionally, in this type of garbage processing device,
For example, as shown in FIG. 10, the kitchen waste discharged from the drain pipe of the sink is put into the cage strainer 2 through the supply pipe 1, the strainer 2 is rotated at a high speed to be dehydrated by centrifugal force, and the dehydration is performed. The generated water is drained from the peripheral wall small hole 2a of the strainer 2 through the drainage channel 3, and as shown in FIG. 11, the scraper attached to the peripheral wall inner surface 2b is scraped off by the blade 4 which is pressed against the peripheral wall inner surface 2b of the strainer 2 and In some cases, the scraped scraps are sequentially pushed upward by the blade 4 so as to overflow from the upper opening 2c of the strainer 2 and put into a recovery chamber (not shown) through the recovery passage 5 shown in FIG.

[0003]

By the way, the garbage that flows into the strainer 2 may include paper-like garbage such as paper, vinyl, or plastic film. However, since the sheet-like kitchen waste is strongly adhered to the inner surface 2b of the strainer 2 during the dehydration, it cannot be scraped off by the blade 4 and the blade 4 and the inner surface 2b of the peripheral wall are not scraped off.
Often gets caught between. Therefore, conventionally, there is a problem in that the sheet-like kitchen waste sandwiched in such a way becomes an obstacle, and it is impossible for the blade 4 to cleanly scrape off other kitchen waste that adheres to the inner surface 2b of the peripheral wall.

Therefore, an object of the present invention is to make it possible to reliably remove the sheet-like kitchen waste that adheres to the inner surface of the peripheral wall of the strainer during dewatering in the kitchen waste processing apparatus as described above.

[0005]

Therefore, what is stated in claim 1 is, for example, as shown in the following illustrated embodiment,
Put the kitchen waste discharged together with the water into the strainer 15, rotate the strainer 15 at high speed, and dehydrate by the centrifugal force.
The water generated by the dehydration is drained from the small hole 35 in the peripheral wall of the strainer 15 through the drainage channel 18, while the blade 30 is pressed against the inner surface 15c of the peripheral wall of the strainer 15 to scrape off the garbage attached to the inner surface 15c of the peripheral wall. In the garbage processing device 10 in which the scraped scraps are sequentially pushed upward by the blade 30 and overflowed from the upper opening 24 of the strainer 15 and put into the recovery chamber 12, the friction coefficient of the inner surface 15c of the peripheral wall of the strainer 15 is increased. It is characterized by being different in the circumferential direction.

According to a second aspect of the present invention, for example, as in the embodiment shown in FIG. 9 below, the kitchen waste discharged together with water is put into a strainer 15 and the strainer 15 is rotated at a high speed to be dehydrated by centrifugal force. The water generated by the dehydration is drained from the small hole 35 in the peripheral wall of the strainer 15 through the drainage channel 18, while the inner surface 15 of the peripheral wall of the strainer 15 is drained.
The blade 30 is pressed against c to scrape off the garbage attached to the inner surface 15c of the peripheral wall thereof, and the scraped garbage is sequentially pushed upward by the blade 30 so as to overflow from the upper opening 24 of the strainer 15 to recover the recovery chamber. In the kitchen waste processing device 10 to be put in the inside 12, the strainer 1
5 is provided with a groove 50 that intersects the circumferential direction on the inner surface 15c of the peripheral wall 5 of FIG.

[0007]

According to the first aspect of the present invention, during dehydration, for example, when a sheet-shaped kitchen waste is sandwiched between the peripheral wall inner surface 15c of the strainer 15 and the blade 30, between the sheet-shaped kitchen waste and the peripheral wall inner surface 15c. The frictional force that occurs on the surface changes, increasing or decreasing. Then, in response to the change in the frictional force, the strainer 15 is rotated to increase or decrease the force to rotate the sheet-like kitchen waste, which is repeatedly changed. As a result, the sheet-like kitchen waste comes out of between the blade 30 and the inner peripheral wall surface 15c.

According to the second aspect of the present invention, for example, a sheet-like kitchen waste is formed on the inner surface 15 of the peripheral wall of the strainer 15 during dewatering.
When it is sandwiched between c and the blade 30, the edge portion of the groove 50 intermittently hits the sheet-like kitchen waste to squeeze the kitchen waste. Then, depending on the squeezing of the edge portion, the force to rotate the sheet-like kitchen waste increases or decreases repeatedly due to the rotation of the strainer 15, which changes repeatedly.
As a result, the sheet-like kitchen waste comes out of between the blade 30 and the inner peripheral wall surface 15c.

The garbage processing device 10 has an inverted L-shaped supply pipe 21 having one end connected to the disposer 20, which is connected to the upper side of the main body case 11. Then, the other end of the supply pipe 21 is deeply inserted into the strainer 15. Then, the disposer 20 is attached to the sink 23 of the sink via the drain pipe 22.

By the way, the garbage processing apparatus 10 of the illustrated embodiment
Then, although omitted in FIG. 5, a lid member is attached to the main body case 11 on the upper side of the strainer 15, and as shown in FIG.
The cover member 25 is covered with the strainer 15 with a part of the window 26 left.

The cover member 25 is provided with an elongated hole 25a through which the supply pipe 21 is inserted, near the arc-shaped outer edge thereof. Then, an inverted L plate-shaped blade support 27 is screwed to the window 26 side of the lid member 25, and a long piece 27 a of the blade support 27 is suspended into the strainer 15. Then, the leaf spring 28 is attached to the piece 27a as shown in FIG. The leaf spring 28 has a plurality of elongated elastic portions 28b extending parallel to each other from one side of the mounting plate portion 28a. Then, the blades 30 are attached to the tips of the elastic portions 28b.

As shown in FIG. 4, the blade 30 includes a U-shaped portion 30a to which the elastic portion 28b of the leaf spring 28 is attached,
And a pressing portion 30b extending in an arc shape. The pressing portion 30b is formed by bending with the same curvature as the inner surface 15c of the peripheral wall of the strainer 15, and the tip end side thereof is formed by the strainer 1
3 toward the downstream side in the rotation direction of 5 (direction of arrow A in FIG. 4).
As shown in FIG. Then, the plurality of pressing portions 30b are held in parallel with each other at the same intervals and provided in multiple stages. Then, the edges 30c of the pressing portions 30b are respectively connected to the elastic portions 2 as shown in FIG.
It is pressed against the inner wall surface 15c of the strainer 15 by 8b.

The strainer 15 against which the blade 30 is pressed in this way is made of, for example, stainless steel, and is provided with a large number of small holes 35 in its cylindrical peripheral wall 15b as shown in FIG. Then, as shown in FIG. 1 (the small hole 35 is not shown), the cylindrical peripheral wall 15b is provided with an elongated friction plate 40 in a depth direction (vertical direction in the drawing) orthogonal to the circumferential direction thereof.

The friction plate 40 has an inner surface 40a whose friction coefficient is different from that of the inner peripheral wall surface 15c, for example, the inner peripheral wall surface 1
It is made of a plate material having a friction coefficient larger than that of 5c, and is formed by bending with the same curvature as the inner surface 15c of the peripheral wall.

In this embodiment, as shown in FIG. 2, the friction plates 40 are integrally attached to both side edges of the friction plates 40 by joining molding to the joint plates 15d, 15d of the cylindrical peripheral wall 15b. Further, as shown in FIG. 6, for example, the side edge portions of the joint plate portions 15d and 15d may be bent and joined, and the friction plate 40 may be adhered to the concave portion provided therein.

Now, referring to FIG. 5, when the above-mentioned garbage processing device 10 is used, a start switch (not shown) is used.
Is turned on to drive the motor (not shown) of the disposer 20 and the motor 16 of the strainer 15. Then, the kitchen waste generated in the sink 23 is discharged from the drainage pipe 22 together with water and put in the disposer 20. Then, the strainer 1 crushes the garbage with the disposer 20, and the crushed garbage is supplied to the strainer 1 which is rotated at a high speed by the motor 16 through the supply pipe 21.
Put in 5.

Then, centrifugal force is applied to the garbage with the water contained in the strainer 15 to attach the garbage to the inner surface 15c of the peripheral wall. Then, the water is dehydrated by the centrifugal force through the peripheral wall small holes 35, the water generated by the dehydration is discharged to the strainer storage chamber 13, and further drained to the outside through the drainage channel 18.

On the other hand, the kitchen waste after dehydration adheres to the inner surface 15c of the peripheral wall of the strainer 15. The kitchen kitchen adheres the scraps with the blade 30, and the scraps are pushed upward by the direction of the blade 30.

Then, while the raised garbage is overflowed from the upper opening 24 of the strainer 15 and discharged into the recovery passage 17 and prevented from adhering to the inner surface of the recovery passage 17 by the mesh member 19, the recovery chamber 12 Put it in the collection bag inside.
After that, when the garbage is collected in the collection bag, take it out and replace it with a new one.

By the way, in the illustrated embodiment, during dehydration,
When the kitchen waste that flows into the strainer 15 contains a sheet-like kitchen waste such as paper or vinyl, the sheet-like kitchen waste strongly adheres to the inner surface 15c of the peripheral wall of the strainer 15,
Therefore, it cannot be scraped off by the blade 30, and the edge 30
It may remain sandwiched between c and the inner surface 15c of the peripheral wall.

In this case, however, in this embodiment, when the strainer 15 contacts the inner surface 40a of the friction plate 40 during the high speed rotation of the strainer 15, the frictional force therebetween increases,
When contacting the inner surface 15c of the peripheral wall, the frictional force therebetween decreases and the frictional force relatively changes. Then, in response to the change in the frictional force, the strainer 15 is rotated to increase or decrease the force for rotating the sheet-like kitchen waste, which is repeatedly changed. As a result, the sheet-like kitchen waste comes out of between the edge 30c and the inner surface 15c of the peripheral wall.
Then, the sheet shape eventually collapses, and the kitchen waste is scraped up by the blade 30 and pushed up.

By the way, in the above-described first embodiment, the inner surface 40a is determined by the friction coefficient of the inner surface 15c of the peripheral wall of the strainer 15.
Although the friction plate 40 having a large coefficient of friction is provided in the strainer 15, conversely, the friction plate 40 having a smaller friction coefficient in the inner surface 40a may be provided in the strainer 15.

In this case, during high speed rotation of the strainer 15,
When the sheet-like garbage contacts the inner surface 40a of the friction plate 40, the frictional force between them becomes small, and when it contacts the inner surface 15c of the peripheral wall, the frictional force between them becomes large. Therefore, in the same manner as described above, the strainer 15 is changed according to the change in the frictional force.
As a result of the rotation of, the force to rotate the sheet-like garbage becomes stronger or weaker and repeatedly changes, so that the sheet-like garbage comes off between the edge 30c and the inner surface 15c of the peripheral wall.

The friction plate 40 shown in FIG. 1 is provided linearly in the depth direction of the strainer 15. However, the friction plate 40 may be inclined as shown in FIG. 7, for example. Further, as shown in FIG. 8, a plurality of friction plates 40 may be provided in a scattered manner.

The present invention can also be configured as in the following embodiment shown in FIG. 9, for example.

In this embodiment, both joint portions 15d and 15d of the cylindrical peripheral wall 15b of the strainer 15 are formed in a concavo-convex shape, respectively, and a plurality of grooves 50 are formed inside the joint portions 15d and 15d in a direction orthogonal to the circumferential direction. The configuration is provided.

When the sheet-like kitchen waste is sandwiched between the inner wall 15c of the peripheral wall and the blade during dewatering, the edge 50a is intermittent when the groove 50 passes through the inner surface 15c of the peripheral wall of the sheet-like kitchen waste. Hit the kitchen waste against the target. Then, depending on the squeezing of the edge 50a, the force of the strainer 15 to rotate the sheet-like garbage becomes stronger or weaker repeatedly due to the rotation of the strainer 15. As a result, the sheet-like kitchen waste comes off between the blade 30 and the inner wall surface 15c of the peripheral wall.

[0031]

Therefore, according to the present invention, even if the sheet-like kitchen waste is sandwiched between the inner surface of the peripheral wall of the strainer and the blade pressed against the inner wall of the strainer during dewatering, according to the invention of claim 1, the peripheral wall of the strainer is The friction coefficient of the inner surface is made different in the circumferential direction, and the frictional force generated between the inner surface of the peripheral wall and the sheet-like garbage is changed, or
In the one described in (1), a groove that intersects the circumferential direction is provided on the inner surface of the peripheral wall of the strainer, and the edge of the groove is applied to the sheet-like garbage to squeeze it, so that the sheet-like garbage is rotated with the rotation of the strainer. As a result of repeatedly changing the force to make it stronger or weaker, the sheet-like garbage can be removed from between the blade and the inner surface of the peripheral wall, and thus the sheet-like garbage that adheres to the inner surface of the peripheral wall of the strainer can be reliably removed. .
