Technical Field

The invention relates to the technical field of kitchen waste treatment equipment, in particular to a kitchen waste treater.

Background

Along with the enhancement of environmental awareness and the increase of health concept of people, the kitchen waste disposer is more and more widely applied. The kitchen garbage disposer is a small-sized electric appliance installed at a water outlet of a washing pool, a fixed seat is communicated with the water outlet of the washing pool through a connecting joint, and a crushing cavity or a water discharging chamber in the fixed seat is communicated with a sewer.

However, the kitchen garbage disposer in the prior art still has the following defects: after the motor is used for about 20-30 minutes, the temperature of the motor is too high, and a protector is generally tripped to protect the motor so as to prevent the motor from being burnt due to the too high temperature. Therefore, the current kitchen waste disposer is not suitable for overlong single use, and generally can not be continuously used for more than 20 minutes. Thus, the kitchen waste disposer is difficult to be normally used in public dining halls outside families such as restaurants, school dining halls, and company dining halls, and has great use limitation.

In recent years, technicians adopt structures such as cooling water channels and blades to cool the motor so as to prolong the single use time, and the structures are different and have different lengths. However, as the applicant knows, a kitchen waste disposer with good heat dissipation effect and long continuous service time of a motor is still lacking in the market at present, so that the kitchen waste disposer is suitable for occasions such as public dining halls outside families, such as restaurants, school dining halls, company dining halls and the like.
