a refrigerator

Abstract

The invention discloses a refrigerator, and relates to the technical field of refrigeration equipment. A lifting mechanism used for ascending and descending a storing part is stable in structure, andthe possibility of losing the lifting function of the lifting mechanism is lowered. The refrigerator comprises a storage box and a drawer door assembly, and further comprises a driving module; the drawer door assembly comprises a drawer door plate, a drawer base and the storing part which is located on the inner side of the drawer base; the automatic lifting mechanism is arranged between the storing part and the drawer base and comprises one or more sets of hinge rod assemblies, and the hinge rod assemblies comprise first hinge rods and second hinge rods, wherein the middles of the first hingerods and the middles of the second hinge rods are hinged to each other; the lower ends of the first hinge rods are hinged to the drawer base, and the upper ends of the first hinge rods are slidably connected with the storing part; the lower ends of the second hinge rods are slidably connected with the drawer base, and the upper ends of the second hinge rods are hinged to the storing part; and thedriving module is used for driving the upper ends of the first hinge rods to slide in the horizontal direction or driving the lower ends of the second hinge rods to slide in the horizontal directionto enable the storing part to ascend or descend. The refrigerator is used for refrigerating food.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] Most of the refrigerators in the prior art adopt a drawer-type design, which is convenient for taking and placing food and has a large effective space. But because the drawer on the bottom floor of the refrigerator is arranged at a relatively lower position, the user needs to bend over or squat down significantly during use, which brings inconvenience to the user, and when the food placed in the drawer is relatively heavy, bending Lifting heavy objects with the waist or squatting is likely to cause damage to the user's waist muscles. [0003] In order to solve the above problems, the prior art provides a refrigerator, such as figure 1 As shown, it includes the drawer 01 and the base 02 located under the drawer 01, and the X-shaped lifting frame 03 that can be stretched up and down and can be positioned after stretchi...

Problems solved by technology

[0004] But due to figure 1 The middle left upper link 031 and the left lower link 032 are not on the same vertical line, and the right upper link 034 and the right lower link 035 are not on the same vertical line. 033 is hinged with the lower end of the corresponding left upper link 031, the upper end of the right lower link 035 is respectively hinged with the lower end of the corresponding right upper link 034 through the right synchronous link 036, and the screw mandrel 037 is supported on the left synchronous link 033 and the right synchronous between the connecting rods 036, so when the X-shaped elevating frame 03 is under the downward pressure of the drawer 01 and the food contained therein, the screw rod 037 will be pushed toward the middle by the left synchronous link 033 and the right synchronous link 036, which is extremely It is easy to cause the screw rod to slip. Once the screw rod slips, this will cause the X-shaped lifting frame 03 to be unable to expand and contract vertically, making its lifting function invalid

Plus, if figure 1 As shown, the structure of the X-shaped lifting frame 03 is trapezoidal, and the structure is unstable. When the drawer 01 and the food contained therein are too heavy, the structure at the hinge of the upper end of the right lower link 035 and the lower end of the right upper link 034, And the structure at the hinge of the upper end of the right lower link 035 and the lower end of the right upper link 034 is easily damaged. Once these two structures are damaged, the X-shaped lifting frame 03 cannot be stretched up and down in the vertical direction, making its lifting function invalid
