Food processor

Abstract

The invention provides a food processor, comprising: a machine base having a receiving cavity; a cup body, with the cross-sectional area of the top end of the cup body being larger than the cross-sectional area of the lower end of the cup body, the cup body being arranged on the frame, and a spoiler rib being arranged on the inner wall of the cup body; a stirring assembly one end of which extendsinto the inside of the cup body, and the other end of which is connected with a permanent magnet direct current motor; a permanent magnet dc motor disposed in the accommodation chamber, wherein the speed range of the permanent magnet dc motor is from 10000 rpm to 18000 rpm. By keeping the rotational speed of the permanent magnet dc motor between 10000 rpm and 18000 rpm, As a result, when too manyingredients are added to the food processor, namely when the load is large, the speed of the permanent magnet dc motor will not be lower than 10000rpm, which effectively ensures the crushing effect ofthe food materials, and when the load is small, the speed of the permanent magnet dc motor will not exceed 18000rpm, which effectively reduces the noise of the food processor and improves the user experience.

Description

technical field [0001] The invention belongs to the technical field of kitchen appliances, and in particular, relates to a food processor. Background technique [0002] At present, food processing machines such as wall breakers mostly use AC series motors. Due to the inherent mechanical characteristics of AC series motors, the speed of the wall breakers will be very high at light loads, reaching over 22,000 rpm, which will generate more than 22,000 rpm. The noise of 90DB seriously affects the user experience. The existing solution is to reduce the no-load speed of the AC series motor, but this method also reduces the load characteristics of the AC series motor, so that when the AC series motor is under a large load, for example, when the load torque is greater than or equal to 0.5N.m , the output speed will be lower than 10000rpm, so the wall breaking effect will be worse. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the technical problems...
