Description

A kind of refrigerator

Technical Field

The invention relates to the technical field of storage equipment, in particular to a refrigerator.

Background

With the increasing improvement of the quality of life, more and more multi-door refrigerators with the characteristics of large volume, multiple functions, classified storage and the like are provided, and the intelligent requirement degree of the refrigerator products by people is also higher and higher. The plywood of current refrigerator product is the unchangeable plywood of fixed position, and shaping courage muscle on the inside relative lateral wall of refrigerator storeroom usually, the plywood place on courage muscle can. In order to make the height-adjustable of plywood, generally reserve the several courage muscle on the inner wall of storeroom to the user can place the plywood on the courage muscle of co-altitude not, changes the height of plywood, but, because the position of courage muscle can not change, so the clearance size between the plywood can not be adjusted at will according to the size of depositing article, causes the inside space utilization of refrigerator low, influences user experience. In addition, in recent years, the demand for large-capacity refrigerators has been gradually increased, and the height of the refrigerators has been increased, so that it is difficult to access the articles stored on the uppermost layer plate, which has been a problem for users.

Based on above-mentioned problem, but some plywood height automatically regulated's refrigerator has appeared on the market, as shown in fig. 1, this refrigerator includes plywood 001 and the ball screw subassembly of being connected with plywood 001, the ball screw subassembly includes supporting ball screw 002 and ball nut 003 and fixes the drive gear 004 in ball screw 002 bottom, drive gear 004 is connected with motor 005 and is driven rotatoryly by motor 005, the both ends of plywood 001 respectively are fixed with a mount pad 006, mount pad 006 is fixed with plywood 001, be equipped with two through-holes on the mount pad 006: first through-hole 007 and second through-hole 008, ball nut 003 set up in first through-hole 007 thereby fixed with mount pad 006, wear to be equipped with guide bar 009 in the second through-hole 008, play the effect of balanced support and direction to mount pad 006, effectively prevent mount pad 006 and plywood 001 slope, be provided with fixing base 010 respectively on the top and the bottom of ball screw 002 and guide bar 009, the lateral wall fixed connection of this fixing base 010 and storeroom. When the ball screw 002 is rotated by the motor 005, the ball nut 003 ascends or descends on the ball screw 002, turning the rotational force into an axial force, thereby driving the mount 006 and the laminate 001 to ascend or descend.

In the scheme, two groups of ball screw assemblies are respectively arranged at two sides of the laminate 001, when the laminate 001 is used, the two motors 005 respectively drive the corresponding transmission gears 004 to rotate, so as to drive the corresponding ball screws 002 to rotate, so that the corresponding ball nuts 003 move up and down, thereby driving the laminate 001 to move up and down, however, the two motors 005 respectively control the corresponding ball screw assemblies to operate, the two motors 005 can not operate synchronously, when the two motors 005 operate asynchronously, the rotating speeds of the two ball screws 002 are different, the up and down moving speeds of the two ball nuts 003 are different, so that the two ball nuts 003 are not in the same plane, the laminate 001 is inclined, the friction force of the threaded connection surface between the ball nut 003 and the corresponding ball screw 002 is increased, and further the ball nut 003 and the corresponding ball screw 002 can not rotate relatively, influence plywood 001 and go up and down normally, reduce user experience and feel.
