Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirrer for a food waste disposer which can easily dispose of food waste at home.

[0002]

2. Description of the Related Art FIG. 3 is a cross-sectional view of a domestic food waste processing machine that the present applicant has invented and previously applied, and shows a bottomed cylindrical plastic container 1 having an opening at the top. An upper lid 2 that is detachably attached to the top opening of the cylindrical container 1, a stirring device 3 that stirs the inside of the cylindrical container 1, and a wheel 4 attached to the lower portion of the cylindrical container.

The cylindrical container 1 has a double wall structure in the lower half portion of its side wall and a bottom wall, and the inner wall side 5 of the double wall structure extends integrally above the portion of the double wall structure. It also constitutes the upper half of the side wall, and the outer wall side 6 fits into the outer periphery of the reduced lower half of the inner wall side 5 and is connected to the upper half of the inner wall side 5 without steps. The portion of the double wall structure of the cylindrical container 1 covers a little above the stirring area (range within which the stirring blade 7 reaches) of the stirring device 3, and the stirring blade 7 is provided at the bottom of the inner wall side 5 of the double wall structure. R is attached to a shape substantially along the rotation trajectory of the tip of the.

A plurality of openings 8 are formed in the upper lid 2, and water (rainwater) does not pass through the openings 8 but water vapor from inside penetrates through the waterproof moisture-permeable membrane 9 of Gore-Tex (registered trademark). Is stretched. A waterproof / moisture permeable membrane is a membrane that does not allow water to permeate under the conditions of use but allows water vapor and air to permeate. For example, a continuous porous structure film obtained by stretching polytetrafluoroethylene (trade name GORE-TEX = registered Trademark). Water vapor inside the container naturally diffuses to the outside of the container through the waterproof and moisture permeable membrane due to the difference in the partial pressure of water vapor inside and outside the container, and outside air naturally diffuses into the container through the waterproof and moisture permeable membrane. come.

The stirrer 3 has a shaft 10 horizontally rotatably supported on the side wall of the cylindrical container 1 and a plurality of stirring blades 7 radially attached to the shaft 10. The stirrer 3 is rotated by human power or an electric motor. Driven. The wheel 4 is rotatably attached to the outer wall side 6. The outer wall side is dented toward the inner wall side 5 at a position corresponding to the wheel 4, and the wheel 4 is housed so as not to protrude from the contour of the cylindrical container 1.

[0006] When using this food waste disposing machine, a landing material for microorganisms such as sawdust is put into the cylindrical container 1 from the top opening to the extent that the tip of the stirring blade 7 is seen, and the garbage and the food waste are put in the landing material. One or more kinds of microorganisms suitable for decomposing garbage are added, and the inside is stirred to mix the garbage and the microorganisms. When the decomposition of food waste by microorganisms proceeds, the water generated by the decomposition is once absorbed by the sawdust, but due to self-heating during decomposition, it becomes steam, and due to the difference in the partial pressure of steam inside and outside the container, the waterproof moisture-permeable membrane. It escapes through 9 and is continuously emitted outside the container. For this reason, the inside of the container does not become sticky due to moisture, and because of the double-wall structure, it has good heat insulation, and because the waterproof and moisture-permeable membrane stretched over the ventilation port, there is no direct infiltration of outside air and the outside air temperature is high. Even if the temperature drops, the temperature inside the container does not easily drop, and the inside of the cylindrical container 1 is maintained in an environment suitable for microorganisms that decompose food waste, and the food waste is quickly decomposed into water and carbon dioxide without spoilage.

[0007]

By the way, in the cylindrical container 1 of the above-mentioned food waste disposer, the R is attached to the bottom of the inner wall 5 so as to substantially follow the rotational trajectory of the tip of the stirring blade 7. , There is almost no dead point that causes poor stirring, and the stirring blade 7 is rotated to uniformly stir. For example, when a large solid garbage is caught between the inner surface of the inner wall 5 and the stirring blade 7. A large force is required to crush the food waste and rotate the stirring blade 7, and when the food waste cannot be crushed, the stirring blade 7 cannot be rotated, and when the drive source is an electric motor, it burns out. There is a problem of blown fuses and blown fuses.

The present invention is intended to solve the above-mentioned problems of the food waste disposer relating to the invention of the prior application, and even when a large solid food waste is bitten between the inner surface of the container and the agitating blade, the agitating blade is applied. An object of the present invention is to obtain a stirring device that can reduce the load and can be continuously rotated.

[0009]

DISCLOSURE OF THE INVENTION The present invention relates to a stirrer for a food waste disposer including a shaft rotating in a processing container and a stirring blade radially mounted around the shaft, and a part or all of the stirring blade. Is made of an elastic body, and the portion thereof is curved freely. As a preferred specific embodiment, the tip of the stirring blade is made of an elastic body, and in that case, the tip of the elastic body is It is possible to attach a wide auxiliary member to, and the elastic body is a coil spring. The elastic body may be any spring such as a spring other than a coil spring, a rubber product, a plastic product, or the like as long as it deforms in response to stress and returns to its original shape when the stress is removed.

[0010]

In the above stirring device, a part or all of the stirring blade is made of an elastic body and the portion is freely curved. Therefore, the stirring blade bites a large amount of solid garbage between the stirring blade and the inner surface of the container. At this time, as the stirring resistance increases, the elastic body portion is distorted and curved, and the stirring blade rotates so as to slip through the garbage.

[0011] On the other hand, when the stirring blade moves up to separate the contents (garbage refuse + flooring material) in the processing container and raises the tip of the contents, the load on the stirring blade suddenly decreases. The curved elastic body returns to its original shape, and the stirring blade scatters the contents in the processing container. The entire stirring blade can be made of an elastic body, or the middle of the stirring blade can be made of an elastic body, but it is preferable to use an elastic body at the tip portion of the stirring blade in order to suppress the scattering of the contents.

Further, when the tip portion of the stirring blade is made of an elastic body, the elastic body may be wide. For example, when a coil spring or the like is used, the raw material put on the flooring material is used. The effect of drawing dust into the flooring material is small. In such a case, it is advisable to attach a wide auxiliary member to the end of the elastic body to enhance the pulling action of the garbage.
