Abstract

The invention provides a power output device, an ice crusher and a refrigerator. According to the power output device, except for the motor and the mounting screws, all the power output device is formed by engineering plastics, the brushless motor is selected as a power source, and the brushless motor drives the gear train to achieve integrated output shaft output. The internal structure is more compact, the thickness of the gearbox shell of the power output device can be effectively compressed to be within 30 mm, the requirements of customers for light and thin products are met, and the space utilization rate of a refrigerator is increased. The brushless motor is high in safety and can meet the IEC explosion-proof test standard, the rotating speed and the rotating direction can be flexibly adjusted through a driving algorithm, the phenomena of ice clamping and rotation blocking are effectively reduced, and the ice crushing effect is optimized. According to the ice crusher, the output shaft integrally formed by engineering plastics is adopted, and the structure of the output shaft can realize power output without assembly and matching, so that faults caused by unreliable assembly among mechanical parts can be effectively avoided, and the use feeling of the ice crusher is improved.

Description

technical field [0001] The present application relates to the field of refrigerator components, in particular to a power output device, an ice crusher and a refrigerator. Background technique [0002] The existing ice crushers on the market have relatively large dimensions. The shell thickness of the power output device usually exceeds 42mm, which will directly affect the utilization rate of the internal space of the refrigerator. Therefore, considering the integrated space layout inside the refrigerator, it is necessary to design a new type of flat ice crusher power output device. [0003] In addition, the ice crushers on the market usually use a brushed DC motor as their internal power source. There are carbon brushes inside the brushed motor, and electric sparks will be generated when the carbon brushes are switched to connect electrodes. The internal structure of this motor cannot meet the IEC explosion-proof test standard [0004] Moreover, since the brushed motor h...
