Description

  The present invention relates to a disposer for pulverizing garbage with water and a sink equipped with the disposer.

  For example, in a disposer that grinds garbage with a rotating crushing blade, the joint between the crushing chamber case (hopper) containing the crushing chamber and the motor case (bracket) that drives the crushing blade and crushing blade is not sealed. When it is sufficient, garbage crushed from the joint portion flows out to the outside, and the area around the disposer may be soiled or a bad odor may be generated.

  In order to solve such a problem, for example, a technique has been proposed in which one packing that seals two places in a double circle shape at the joint is arranged to improve the sealability of the joint (for example, Patent Documents). 1).

When this technology is used for a disposer, two joints can be sealed in a double circle shape by packing disposed at the joint between the crushing chamber case and the motor case. The sealability can be improved and the smashed garbage can be prevented from flowing out from the joint.
