Description

Food waste treating apparatus installed on sink

The present invention relates to a food waste treatment apparatus for installing a sink, and more particularly, to a food waste treatment apparatus for installing a sink having improved cleaning efficiency of an inner wall surface of a treatment tank.

In general, a food waste treatment apparatus used at home is configured to dry the food waste in order to reduce the amount of food waste and prevent wet food waste from being taken out.

In addition, although a food waste treatment apparatus for decomposing treatment using microorganisms has been developed, most users use a method of collecting food waste and putting it in a separate apparatus for treatment.

In consideration of such a problem, a food waste treatment apparatus for installing a sink installed under the sink and disposing of food waste discharged through a sewer and food waste input by a user has been developed.

As a prior art for a food waste treatment apparatus installed directly under the sink, Registration Patent No. 10-1627427 (food waste treatment apparatus for installing a sink) has been disclosed.

The food waste treatment apparatus includes a treatment tank having a space formed therein for decomposing and processing the food waste input through the input unit into microorganisms.

When food waste is treated using a food waste treatment device, sludge, which is a result of food waste treatment, is attached to the inner wall of the treatment tank. If the sludge is not removed, a severe odor is generated.

The conventional food waste treatment apparatus has insufficient configuration for easily removing sludge attached to the inner wall surface of the treatment tank, so the operator periodically disassembles the food waste treatment apparatus and then removes the sludge attached to the inner wall surface of the treatment tank. Since it has to be performed, there is a problem in that the maintenance work of the food waste treatment apparatus is inconvenient.

In addition, in some conventional food waste treatment apparatuses, a nozzle for spraying washing water on the inner wall of the treatment tank is provided, but the installation structure of the nozzle is complicated and a large amount of space is occupied for installing the nozzle inside the treatment tank. there was

In addition, the conventional food waste treatment apparatus lacks a structure capable of uniformly spraying washing water on the entire inner wall surface of the treatment tank, so that the sludge is removed only from a portion of the inner wall surface of the treatment tank to which the washing water is sprayed, and the washing water is not sprayed. The sludge was not removed from the rest of the inner wall of the tank and remained as it was, so there was a problem in that the cleaning efficiency of the inner wall of the treatment tank was low.
