Description
Technical Field
The invention belongs to the technical field of refrigerators, and particularly relates to a refrigerator shelf synchronous lifting device.
Background
At present, most refrigerator shelves are single rectangular plate glass shelves or flat plastic shelves, and the glass shelves are placed on or clamped on the tank liner ribs through structures matched with the tank liner per se to be fixed. In the prior art, most of refrigerator shelves are placed on ribs on the left side and the right side of an inner container, the ribs are provided with a plurality of different heights, and the positions of the shelves are adjusted according to requirements. But the height adjustment needs to take out all the articles on the shelf, place the shelf at a proper position and then place the articles on the shelf; for a high and deep large-capacity refrigerator, it is inconvenient to store and take out food on the shelf. And only a few fixed heights can be adjusted, and the effect of stepless adjustment of the shelf cannot be effectively realized. Meanwhile, the operation time is long, the amount of cold air is increased, the energy consumption loss is large, and the like.
At present, a small number of brands of refrigerators in the market release refrigerators with liftable shelves, and the storage requirements of customers on foods and other articles with different heights are met. As in the prior patents: according to the shelf assembly and the refrigerator (patent number: CN104764280A), the clamping grooves are formed in the side wall of the refrigerator, and the plurality of rotary knobs are arranged in the clamping grooves at intervals to support the shelf, so that the design cannot be used for adjusting any height as required, and the adjusted height can only be the distance between the two rotary knobs. As another prior patent application: a synchronous lifting system of a refrigerator rack and a control method thereof (publication number: CN106595211A) are provided, when the assembly of a rack body and a lifting mechanism is completed, a connecting piece is slidingly sleeved on a guide rod, a sliding nut is sleeved on a transmission screw rod, and a motor drives the transmission screw rod to rotate to drive the lifting of the sliding nut so as to drive the rack body to move along the guide rod; the controller is configured to control the rotation speed and the number of steps of each motor to gradually approach synchronization according to the rotation speed and the number of steps of the corresponding motor fed back by each sensor. The running state of the motors is constantly detected by the sensor and fed back to the controller for logic analysis, the driving compensation is constantly adjusted, and then the running signals of the driving motors are adjusted, so that the aim of always keeping the two motors synchronously running is fulfilled.
In the above patent, the lifting problem of the shelf is realized by adopting a left lifting mechanism and a right lifting mechanism, but the left lifting mechanism and the right lifting mechanism are difficult to realize synchronization; the problems of difficult synchronous lifting control and unbalanced shelves in the lifting process exist. The invention provides a refrigerator shelf synchronous lifting device, which realizes shelf lifting through a single driving device and avoids the problem of shelf operation asynchronism caused by a plurality of driving devices.
