[0042] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] During the operation of the refrigerator, vibration noise will be generated, which will affect the user experience. The main noise source of the refrigerator is the compressor.

[0045] The compressor is the core of refrigeration equipment (such as air conditioners, refrigerators, freezers, etc.), and directly determines the performance of refrigeration equipment. The working principle of the compressor is: inhale low-temperature and low-pressure refrigerant from the suction pipe, then compress the refrigerant through the compressor, and then discharge high-temperature and high-pressure refrigerant to provide power for the refrigeration cycle. However, during the operation of the compressor, on the one hand, the eccentric operation of the compressor structure forces the compressor to vibrate, and on the other hand, the pressure shock of suction and exhaust will also cause compressor vibration.

[0046] The vibration generated when the compressor is working will be transmitted to the base plate used to support the compressor, causing vibration and noise in the entire refrigerator. The structure may cause the refrigerator to become unstable or even cause the internal pipes of the refrigerator to break, affecting the working reliability of the refrigeration equipment.

[0047] Most of the refrigerators sold on the market have a freezer compartment, and the compressor is set below the freezer compartment, in a cavity near the back of the box. The compressor base plate is installed at the bottom of the refrigerator to support the compressor. In related technologies, generally, soft materials such as rubber pads are set on the compressor base plate, or silencers, sound insulation foams, etc. are set in the compressor housing to reduce the noise generated by the compressor. However, the effect of reducing the noise generated by the resonance between the compressor and the base plate is very small, so the refrigerator still has noise problems.

[0048] At present, most refrigerators use one compressor. However, for some large-capacity refrigerators, using one compressor may cause poor refrigeration effect or uneven refrigeration, and when the compressor fails and is not discovered in time, it may cause the deterioration of the items in the refrigerator. Therefore, in the embodiment of the present disclosure, Figure 1 and Figure 2 As shown, two compressors are arranged in the refrigerator 10, namely, a first compressor 11 and a second compressor 12, and the two compressors are arranged together on the bottom plate 20. Since the distance between the two compressors on the bottom plate 20 is relatively close, the noise generated by the resonance between the two compressors and the bottom plate 20 will be stronger, so reducing such noise requires avoiding the resonance between the compressor and the bottom plate 20.

[0049] The natural frequency refers to the natural vibration of a structure at a specific frequency when it is stimulated by external forces. This specific frequency is called the natural frequency of the structure. The natural frequency is proportional to the square root of the stiffness. Therefore, by increasing the stiffness of an object, its natural frequency can be changed.

[0050] Improving the rigidity of the bottom plate 20 and changing the natural frequency of the bottom plate 20 are one of the main methods to eliminate the resonance noise between the bottom plate 20 and the compressor.

[0051] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure provides a compressor base plate 20 for a refrigerator and a refrigerator 10 to reduce the noise generated during the operation of the refrigerator 10.

[0052] According to a first aspect of an embodiment of the present disclosure, a compressor base plate 20 for a refrigerator is provided.

[0062] The intersection of the extension line of the fourth rib segment 24 and the first rib segment 21 includes: the fourth rib segment 24 is connected to the first rib segment 21 and a corner is formed at the connection; or the fourth rib segment 24 is not connected to the first rib segment 21 and a gap exists.

[0063] The fourth rib segment 24 and the third rib segment 23 are both disposed along the width direction of the bottom plate 20 .

[0064] The fourth rib section 24 is provided to further define the position of the first compressor 11. The fourth rib section 24, the first rib section 21, the second rib section 22 and the third rib section 23 are arranged together around the first compressor 11 to further enhance the rigidity of the bottom plate 20 where the first placement position 210 is located, and reduce the noise generated when the first compressor 11 is working.

[0067] Optionally, the fifth rib segment 25 is arranged along the length direction of the bottom plate 20 .

[0068] The fifth rib segment 25 and the second rib segment 22 are arranged along the length direction of the bottom plate 20, so that the rigidity of the bottom plate 20 along the length direction can be improved. The third rib segment 23 is arranged along the width direction of the bottom plate 20, so that the rigidity of the bottom plate 20 along the width direction can be improved, thereby improving the overall rigidity of the bottom plate 20, improving the overall deformation resistance of the bottom plate 20, limiting the second compressor 12 to the second placement position 220, reducing the resonance between the bottom plate 20 and the second compressor 12 at this location, and achieving the effect of reducing noise.

[0069] Optionally, one of the first placement position 210 and the second placement position 220 extends along the length direction of the bottom plate 20 , and the other of the first placement position 210 and the second placement position 220 extends along the width direction of the bottom plate 20 .

[0094] The present application provides a compressor base plate 20 for a refrigerator, wherein reinforcing ribs are arranged on the base plate 20, and the reinforcing ribs can be arranged around the compressor, or the compressor is arranged on the upper surface of the reinforcing ribs, and the reinforcing ribs can increase the rigidity of the base plate 20 and improve the natural frequency of the base plate 20, thereby reducing the resonance between the compressor and the base plate 20, thereby reducing noise.

[0095] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
