The invention provides a refrigerator, wherein a compressor 20 is fixed in a refrigerator body shell 50 through the compressor vibration reduction structure 60, and the vibration transmission of the vibration of the compressor 20 to the refrigerator body shell 50 is reduced.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:

the vibration reduction structure 60 of the refrigerator compressor is realized by utilizing the cushion pad 30, the positioning bolt 40 and the mounting seat 10, wherein the cushion pad 30 adopts a rubber pad, and the transmission of radial force of the compressor 20 is reduced through the clearance fit of the rubber pad and the positioning bolt 40; the rubber mat is radially positioned by utilizing the positioning structure of the mounting seat 10, the assembling deviation of the rubber mat and the bolt is controlled, and the stability and consistency of the vibration reduction effect are ensured.

The refrigerator compressor 20 of the present invention is a piston compressor 20, the motor rotates around the Z axis, and the crank connecting rod mechanism drives the piston to move, so the exciting force is larger in the radial direction of the Y direction of the piston movement and the motor rotation direction, and the transmission path in the above direction should be cut off mainly in order to reduce the vibration transmission of the compressor 20. When the cushion is subjected to an exciting force in the direction of movement of the piston, the cushion is simultaneously subjected to a frictional force by the mounting seat 10, the main deformation occurs in the upper portion of the cushion, and the lower portion is almost free from deformation. If the rubber pad contacts the positioning bolt 40, the inside of the upper rubber pad will be squeezed to generate a resilient force, and the excitation of the compressor 20 will be transmitted to the bolt and further to the refrigerator body and the cavity through the mounting base 10, thereby generating a noise vibration problem. The magnitude of the resilience force can be represented by the formula F ═ k × s, where k is the cushion stiffness and s represents the compression deformation with the bolt. Therefore, according to the above experiments and simulations, the present invention has been found that the rubber pad and the bolt are designed to be in clearance fit, that is, s is 0, and the extrusion resilience is weakened to zero, so that the transmission path of the excitation of the compressor 20 can be cut off.

The lower part of the rubber pad of the invention is deformed very little, so that even if there is some contact at this location, the transmitted resilience is not too great. The positioning structure can be designed on the bottom plate to be matched with the annular groove at the lower part of the rubber mat, so that the centering of the axle center of the rubber mat and the axle center of the positioning bolt 40 is ensured, the radial positioning is realized, and the problems of deviation, poor consistency and the like caused by the rubber mat and the positioning bolt 40 in the actual assembly process are solved.

According to the formula of the vibration a ═ F '. omega ^2/k ', wherein a is acceleration, F ' is resilience force borne by the bolt, omega is circular frequency, and k ' is dynamic stiffness of the horizontal direction of the bottom plate, and if F ' and omega are fixed, the dynamic stiffness of the bottom plate can be effectively reduced in vibration transmission. Therefore, the effect of damping and noise reduction is further achieved, the lug boss structure is additionally arranged at the installation position of the rubber mat, the dynamic stiffness in the horizontal direction is effectively increased, and vibration transmission is further inhibited.

Combining the above modification points and verifications, the invention designs the matching structure of the mounting base 10, the positioning bolt 40 and the rubber mat, the second positioning part 113 structure of the mounting base 10 increases the dynamic stiffness in the horizontal direction, and at the same time, a small first positioning part 112 is pressed to perform radial positioning of the rubber mat, or positioning is performed by welding a positioning block, so that the radial clearance matching state of the rubber mat and the positioning bolt 40 is ensured, and the vibration damping effect and the stability thereof can be effectively improved.
