Description

Disposer using low-noise rotating blade

The present invention relates to a disposer using a low-noise rotary blade, and more specifically, it relates to a disposer using a low-noise rotary blade that can effectively reduce grinding noise by improving the structure so that the crushing impact is dispersed while diversifying the crushing step of food waste will be.

The food waste treatment device for the sink, which is usually used in the kitchen of a home or restaurant, is installed below the drain hole of the sink and crushes the food waste generated during the washing process or food cooking process into small sizes through the discharge pipe along with the washing-up sewage. It is a device that disposes of the discharge into the sewer.

Such a food waste treatment device is configured to pulverize food waste by a blade rotating at high speed by receiving the rotational force of the motor. As a result, clogging of outlets and sewers occurs frequently.

Therefore, in Utility Model Registration No. 20-0485302 disclosed in the prior art, the grinding rotary plate forms a triangular grinding blade symmetrically left and right on the upper part, and forms a sewage guide plate inclined to the outside at the lower part, and the outer surface of the grinding rotary plate A crushing ring is installed on the top, and the crushing ring is formed by pressing and bending several crushing ring blades inclined downward in the rotational direction on the upper part, forming several crushing blades bent inward on the inner surface, and crushed food at the bottom A radially '∩'-shaped pulverized material discharge hole is formed so that garbage can be discharged, and the pulverized ring is configured in a ring shape with one side open so that it can be mixedly fit into the housings of various sizes of treatment devices. The technology has been previously presented.

In addition, in another Patent Publication No. 10-2011-0100043, a grinder body connected to the drain port of the sink, and a rotating plate provided with a grinding blade to grind the food waste introduced through the drain hole in the inside of the grinder body are included. In the food waste treatment apparatus according to claim 1, wherein the rotating plate is provided with a pair of the grinding blades and is rotatably coupled to the rotating plate at positions opposite to each other, a discharge hole is formed on the surface to discharge the food waste crushed by the grinding blade. A technology in which a blower blade is installed on the bottom surface of the rotating plate to smoothly discharge food waste discharged through the discharge hole to the drain pipe connected to the grinder body with wind generated by the rotation of the rotating plate has been previously disclosed.

However, the prior art uses the rotary grinding blade and the grinding ring to increase the grinding efficiency of food waste, but most of the food waste is adsorbed to the inner wall of the grinding chamber by centrifugal force and is out of the grinding radius of the rotating grinding blade, so the grinding efficiency is reduced. In particular, food waste with large particles collided with the rotary grinding blade and scattered to the upper part of the grinding chamber, delaying the grinding time and causing serious noise due to grinding impact.
