Refrigerator and shelf lifting control method of refrigerator

Abstract

The invention discloses a refrigerator and a shelf lifting control method of the refrigerator. The refrigerator comprises a refrigerator body and a shelf lifting device, the lifting shelf is arranged in the box body and comprises a shelf, a transmission mechanism and a driving motor for driving the shelf to move up and down within a preset height range through the transmission mechanism; the controller is configured to obtain the current position of the shelf in response to a received shelf lifting instruction; when it is determined that the current position is not the highest point of the preset height range, a driving motor is controlled to drive the shelf to move upwards for preset time, and the running current of the driving motor is detected; when it is determined that the running current is within the preset current range, determining a target rotating speed corresponding to the running current according to the corresponding relation between the preset current and the rotating speed; and controlling a driving motor to operate according to the shelf lifting instruction and the target rotating speed. According to the embodiment of the invention, noise and energy consumption generated by lifting of the shelf can be effectively reduced, and the lifting speed of the shelf is ensured.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a refrigerator and a method for controlling the lifting of a shelf of the refrigerator. Background technique [0002] At present, some refrigerators are equipped with automatic lifting shelves. However, in the existing refrigerators, no matter whether the weight of the items placed on the shelves is light or heavy, the motors driving the shelves to go up and down will run at a set fixed speed. If the fixed speed is set too high, the items placed on the shelves will When the item is too light, it will not only produce unnecessary noise, but also consume extra energy consumption. If the fixed speed is set too low, when the item placed on the shelf is too heavy, the lifting speed of the shelf will be affected. Contents of the invention [0003] Embodiments of the present invention provide a refrigerator and a method for controlling the lifting of the shelves of the refrig...

Problems solved by technology

However, in the existing refrigerators, no matter whether the weight of the items placed on the shelves is light or heavy, the motors driving the shelves to go up and down will run at a set fixed speed. If the fixed speed is set too high, the items placed on the shelves will When the item is too light, it will not only produce unnecessary noise, but also consume extra energy consumption. If the fixed speed setting is too low, when the item placed on the shelf is too heavy, the lifting speed of the shelf will be affected.
