The support plate 3 is used to support and install the first fan 41. The first fan 41 includes a volute and an impeller disposed in the volute.

[0065] Combination Figure 3 As shown, in a first embodiment of the first fan 41, the support plate 3 is provided with a mounting cavity 32 for accommodating the first fan 41. The mounting cavity 32 is an open structure with an opening. Part of the volute is accommodated in the mounting cavity 32, and the other part of the volute extends out of the mounting cavity 32. The volute of the first fan 41 is spaced apart from the inner wall of the mounting cavity 32. The first fan 41 will vibrate when working, and a spacing is preset between the volute and the inner wall of the mounting cavity 32 to buffer the vibration of the volute, so that the support plate 3 has a certain elasticity, which has the advantage of reducing noise.

[0066] The refrigerator provided by the present invention supports and installs the first fan 41 by providing a support plate 3, a part of the volute of the first fan 41 is accommodated in the installation cavity 32, another part of the volute extends out of the installation cavity 32, and the volute is spaced apart from the inner wall of the installation cavity 32. A spacing for buffering the vibration of the volute is preset between the volute and the inner wall of the installation cavity 32, so that the support plate 3 has a certain elasticity to reduce the noise generated by the vibration of the first fan 41. It has the advantages of simple installation, reduced noise and reduced cost.

[0067] Further, the support plate 3 includes a support body 31, a circular arc recessed surface 321 recessed downwardly of the support body 31, and a recessed front wall 322 formed by extending the front edge of the circular arc recessed surface 321 upwardly and connected to the support body 31. The circular arc recessed surface 321 is configured to match the shape of the volute. The circular arc recessed surface 321 and the recessed front wall 322 together define the installation cavity 32.

[0068] Furthermore, an opening of the installation cavity 32 is defined between the rear edge of the arc concave surface 321 and the support body 31. Part of the first fan 41 is exposed to the outside of the installation cavity 32 through the opening. The rear side of the installation cavity 32 is open, which further makes the support plate 3 have a certain elasticity to reduce the noise generated by the vibration of the first fan 41.

[0069] Combination Figure 4 and Figure 5 As shown, the pivot centerline a of the first fan 41 extends from the front to the rear. The pivot centerline a of the first fan 41 is the rotation centerline of the first fan 41.

[0070] refer to Figure 2As shown, the volute includes a volute front wall 411, a volute rear wall 413, and an arcuate side wall 414 connecting the volute front wall 411 and the volute rear wall 413. The arcuate side wall 414 is a U-shaped arcuate structure with a left-right symmetrical structure. The volute front wall 411 and the volute rear wall 413 are respectively arranged on the front and rear sides of the arcuate side wall 414.

[0071] Preferably, the volute further comprises a volute top wall 416. The volute top wall 416, the volute front wall 411, the volute rear wall 413, and the arc-shaped side wall 414 are jointly arranged to form the volute.

[0072] Combination Figure 2 and Figure 3 The arc-shaped side wall 414 is spaced apart from the circular arc recessed surface 321 , and the volute front wall 411 is spaced apart from the recessed front wall 322 .

[0073] Specifically, a preset distance is provided between the arcuate side wall 414 and the arcuate concave surface 321, and a preset distance is provided between the volute front wall 411 and the concave front wall 322. Parts of the arcuate side wall 414 and the volute rear wall 413 extend out of the installation cavity 32 through the opening of the installation cavity 32. A buffer space for buffering the vibration of the volute is formed between the volute and the support plate 3, so that the support plate 3 has a certain elasticity to reduce the noise generated by the vibration of the first fan 41.

[0074] Furthermore, the first fan 41 also includes a clamping portion formed by the volute and positioned and clamped with the support plate 3. The support plate 3 also includes a positioning portion positioned and installed with the clamping portion. The clamping and disassembling installation method of the positioning portion and the clamping portion simplifies the installation process of the first fan 41 on the support plate 3, and also plays a role in reducing noise.

[0075] refer to Figure 5 As shown, the clamping portion includes a clamping groove 415 formed by the front wall 411 of the volute. The positioning portion includes a positioning block 324 extending from the recessed front wall 322 into the installation cavity 32 and clamped into the clamping groove 415.

[0076] Specifically, a portion of the volute rear wall 413 disposed opposite to the slot 415 extends out of the mounting cavity 32 through the opening of the mounting cavity 32. Thus, when the volute vibrates, the positioning block 324 and the slot 415 can move in a small range in the front-rear direction to alleviate the noise generated by the vibration of the volute. Preferably, a portion of the slot 415 is exposed from the support body 31 to preset a buffer space for buffering the vibration of the volute.

[0077] Furthermore, the clamping portion further includes buckles 418 formed by extending the arc-shaped side wall 414 to both sides. The two buckles 418 are respectively and symmetrically arranged on both sides of the arc-shaped side wall 414.

[0078] Part of the arc-shaped side wall 414 extends out of the mounting cavity 32 through the opening of the mounting cavity 32, and the buckle 418 extends outward from the arc-shaped side wall 414. The buckle 418 extends out of the mounting cavity 32 through the opening and abuts against the lower surface of the support body 31. The top of the buckle 418 abuts against the lower surface of the support body 31 in the up-down direction.

[0079] Furthermore, the buckle 418 has an arc-shaped guide surface installed in the opening and an abutting plane abutting against the lower surface of the support body 31. The buckle 418 includes a buckle body, the arc-shaped guide surface is formed on the side of the buckle body, and the abutting plane is formed on the top of the buckle body.

[0080] During the installation process of the first fan 41, the two buckles 418 extend through the opening to the outside of the installation cavity 32 and abut against the lower surface of the support body 31 to achieve the positioning and installation of the first fan 41 in the left and right and up and down directions. At the same time, the positioning block 324 is inserted into the card slot 415 to achieve the positioning and installation of the first fan 41 in the front and back directions. It has the effect of simple installation and reduced noise. When the first fan 41 is installed, a preset spacing is set between the arc-shaped side wall 414 and the circular arc concave surface 321, and a preset spacing is set between the volute front wall 411 and the concave front wall 322. The support plate 3 has a certain elasticity to reduce the noise generated by the vibration of the first fan 41.

[0081] Furthermore, the first fan 41 is tilted downward from the front to the rear, and the volute is tiltedly installed in the installation cavity 32. The arc recessed surface 321 is tilted downward from the front to the rear, and the arc recessed surface 321 is matched with the arc-shaped side wall 414.

[0082] Furthermore, in order to install the first fan 41 of a large size as much as possible in the limited space of the press chamber 11, the pivot center line a of the first fan 41 forms an angle with the horizontal plane and the pivot center line a is inclined in the direction from front to back. Such an arrangement can increase the size of the fan when the size of the press chamber 11 is constant, so as to improve the heat dissipation and cooling effect of the first fan 41 and make full use of the space of the press chamber 11.

[0083] Furthermore, the angle formed by the pivot centerline a of the first fan 41 and the horizontal plane is less than 45°. Preferably, the pivot centerline a of the first fan 41 is inclined downward in the direction from front to back, and the angle formed by the pivot centerline a of the first fan 41 and the horizontal plane is in the range of 5° to 15°.

[0084] Furthermore, the first fan 41 is tilted downward in the direction from front to rear, so that the center of gravity of the first fan 41 is set lower in the direction from front to rear, and the front wall 411 of the volute forms a slot 415, so that the positioning block 324 on the recessed front wall 322 moves backward in the slot 415 along the front-to-back direction, just so that the rear wall 413 of the volute arranged opposite to the slot 415 extends out of the installation cavity 32 through the opening of the installation cavity 32, so that the front wall 411 of the volute and the recessed front wall 322 always maintain a distance from each other, so as to reduce the noise generated by the vibration of the first fan 41.

[0085] Furthermore, the box body 1 includes a bottom plate 12, a press chamber back plate 13 and a press chamber support plate 14. The press chamber back plate 13 is arranged at the rear side of the bottom plate 12. The box body 1 also includes side plates arranged at the left and right sides of the bottom plate 12. The bottom plate 12, the press chamber back plate 13 and the press chamber support plate 14 are made of heat-conducting metal materials.

[0086] The press chamber support plate 14 extends from the front side of the bottom plate 12 to the rear and upward and is connected to the press chamber back plate 13. The press chamber support plate 14 includes a support bottom 141 disposed at the front side of the bottom plate 12 and adjacent to the bottom plate 12, a support inclined portion 142 extending upwardly from the support bottom 141, and a support top 143 extending horizontally backward from the support inclined portion 142. The support top 143 is connected to the press chamber back plate 13. The bottom plate 12, the press chamber back plate 13, the support inclined portion 142, the support top 143, and the side plates together define the press chamber 11.

[0087] The first fan 41 is connected obliquely to the press chamber back plate 13. The lower part of the first fan 41 is mounted by the support plate 3. The back of the first fan 41 is fixed to the press chamber back plate 13, thereby achieving a stable installation of the first fan 41. It has the advantages of stable and reliable structure.

[0088] Combination Figure 6 As shown, the first fan 41 includes a volute and an impeller disposed in the volute. The volute extends backward to be provided with a hook 419 that is engaged with the back plate 13 of the press chamber. Preferably, the volute includes a volute front wall 411, a volute rear wall 413, and an arc-shaped side wall 414 connecting the volute front wall 411 and the volute rear wall 413. The volute rear wall 413 extends backward to form a hook 419.

[0089] The press chamber back plate 13 is provided with a positioning hole 131 extending through the front and rear, and the hook 419 protrudes into the positioning hole 131 and engages with the press chamber back plate 13. Preferably, the hook 419 includes a hook body formed by extending backward from the volute rear wall 413 and a hook portion formed by bending the hook body downward.

[0090] Further, the volute also includes a volute top wall 416 protruding out of the outside of the compressor chamber back plate 13. The volute top wall 416 is provided with a plurality of top air outlets 417 with openings facing upward. The first fan 41 is connected obliquely to the compressor chamber back plate 13. It is understood that the first fan 41 is not connected obliquely to the compressor chamber back plate 13. The top air outlet 417 can also extend out of the outside of the compressor chamber back plate 13 through the connecting channel.

[0091] The outer wall of the compressor chamber back plate 13 is recessed inward to form a gap 132 for accommodating the top exhaust port 417. The volute top wall 416 extends out of the compressor chamber back plate 13, so that the top exhaust port 417 is exposed outside the compressor chamber back plate 13. It has the advantages of compact structure and reasonable heat dissipation air path.

[0092] The front wall 411 of the volute is provided with a front air suction port 412 located in the compressor chamber 11. The bottom plate 12 is provided with a bottom air inlet 121 connecting the inside and outside of the compressor chamber 11. When the first fan 41 is in operation, the air outside the compressor chamber 11 enters through the bottom air inlet 121 on the bottom plate 12, is sucked into the first fan 41 by the front air suction port 412, and then is discharged upward along the outside of the compressor chamber back plate 13 through the top air outlet 417 of the first fan 41. The compressor chamber 11 forms a heat dissipation mode of bottom air intake and rear air outlet, so that the compressor chamber 11 is cooled and heat dissipated, thereby improving the compression refrigeration effect of the compressor 67.

[0093] Furthermore, the pivot center line a of the first fan 41 is inclined downward in a direction from front to rear, and the angle formed between the pivot center line a of the first fan 41 and the horizontal plane is in the range of 5° to 15°.

[0094] The angle formed by the pivot center line a of the first fan 41 and the horizontal plane is equal to the angle formed by the front wall 411 of the volute and the back plate 13 of the compressor chamber. The angle formed by the front wall 411 of the volute and the back plate 13 of the compressor chamber is less than 15°, so that the top exhaust port 417 can discharge air upward along the outer side of the back plate 13 of the compressor chamber.

[0095] Further, the box body 1 includes a back plate 15 extending upward from the press chamber back plate 13. The back plate 15 is adjacent to the upper side of the press chamber back plate 13. The back plate 15 is a heat-conducting metal material.

[0096] Furthermore, the refrigerator further comprises a first condenser 64 disposed inside the rear plate 15. At least part of the pipeline of the first condenser 64 extends in the same direction as the rear plate 15.

[0097] Specifically, when the first fan 41 is running, the air outside the compressor compartment 11 enters through the bottom air inlet 121 on the bottom plate 12 driven by the first fan 41, first cools the compressor 67 of the compressor compartment 11, and then is sucked into the first fan 41 by the front air intake port 412. The air discharged through the top air outlet 417 is discharged upward along the outer side of the compressor compartment back plate 13 to cool the first condenser 64 on the inner side of the rear back plate 15, thereby reusing the air and improving the heat dissipation effect of the refrigerator.

[0098] Furthermore, the refrigerator further comprises an evaporating dish 24 disposed in the press chamber 11 , and a fastener for fixing the support plate 3 to the top of the evaporating dish 24 , wherein the evaporating dish 24 defines a receiving cavity 242 . The evaporating dish 24 is disposed on the bottom plate 12 .

[0099] The installation cavity 32 is formed to extend into the accommodating cavity 242. The evaporating dish 24 and the compressor 67 are arranged adjacent to each other in the left-right direction, so as to give full play to the air suction and heat dissipation effect of the first fan 41.

[0100] Furthermore, the refrigerator further comprises an evaporator arranged in the box body 1, a refrigeration chamber for accommodating the evaporator, and a defrost drain pipe connecting the refrigeration chamber and the accommodating chamber 242. The defrost drain pipe guides the defrost water generated when the evaporator is defrosted into the accommodating chamber 242.

[0101] Furthermore, the refrigerator further comprises a plurality of elastic fixing members 25 disposed in the accommodating cavity 242 and at the bottom of the supporting plate 3, wherein the elastic fixing members 25 comprise elastic materials. The provision of the elastic fixing members 25 can further reduce the noise generated by the vibration of the first fan 41.

[0102] The inner wall of the evaporating dish 24 extends into the accommodating cavity 242 to form a holder 26 for fixing the elastic fixing member 25. One end of the holder 26 is connected to the inner wall of the evaporating dish 24, and the other end of the holder 26 is a free end. An installation space for installing the elastic fixing member 25 is defined between the holder 26 and the evaporating dish 24. The installation method is simple and easy to process.

[0103] Furthermore, the refrigerator further comprises a second condenser 65 disposed in the evaporating dish 24, wherein the second condenser 65 is penetrated by the plurality of elastic fixing members 25. The defrosting water in the evaporating dish 24 can cool the pipeline of the second condenser 65.

[0104] Furthermore, the first fan 41 is a centrifugal fan, which accelerates the air with a high-speed rotating impeller, and then decelerates and changes the flow direction to be discharged from the top exhaust port 417, which has the advantage of good heat dissipation effect.

[0105] Combination Figure 7 As shown, the refrigerator further includes an air outlet 50 arranged at the back of the box body 1.

[0106] The refrigerator further includes a plurality of vertical air guide plates 53 disposed on the back of the box body 1 and spaced apart in the left-right direction. The vertical air guide plates 53 extend vertically from bottom to top.

[0107] The plurality of vertical air guide plates 53 divide the air outlet duct 50 into a plurality of sub-air ducts.

[0108] Furthermore, the box body 1 includes a press chamber back plate 13 for defining the press chamber 11 , and a rear back plate 15 extending upward from the press chamber back plate 13 . The rear back plate 15 is adjacent to the upper side of the press chamber back plate 13 .

[0109] The refrigerator further includes a back air outlet 133 disposed on the press chamber back plate 13 and communicating with the inside and outside of the press chamber 11. The back air outlet 133 is disposed upward. It is understandable that the refrigerator further includes an air inlet communicating with the inside and outside of the press chamber 11.

[0110] When the first fan 41 is running, the air outside the compressor chamber 11 enters the compressor chamber 11 through the air inlet driven by the first fan 41, first cools down the compressor 67 of the compressor chamber 11, and then is discharged outside the compressor chamber 11 through the back air outlet 133. The air outlet of the first fan 41 is connected to the back air outlet 133.

[0111] By providing the vertical air guide plate 53, the airflow discharged from the compressor compartment 11 through the back air outlet 133 can be uniformly discharged upward along the back of the box body 1, which plays a role in guiding the air flow and making the heat dissipation uniform. Therefore, the heat dissipation efficiency of the refrigerator is improved, so as to improve the refrigeration efficiency. Among them, multiple vertical air guide plates 53 are respectively provided on the back plate 15.

[0112] Further, the back plate 15 includes a first side 151 and a second side 152 which are arranged opposite to each other in the left-right direction. The back air outlet 133 is arranged close to the first side 151. The box body 1 also includes side plates which are arranged on the first side 151 and the second side 152 respectively.

[0113] The distance between the bottom of the plurality of vertical air guide plates 53 and the plane where the back air outlet 133 is located gradually increases from the direction from the first side 151 to the second side 152, so that the sub-air ducts away from the back air outlet 133 can also have air flowing through them, thereby ensuring that air flows through each sub-air duct.

[0114] The closer the position is to the back air outlet 133, the more air flows over it, and part of the air needs to flow to the area away from the back air outlet 133. Therefore, the bottom of the vertical air guide plate 53 closer to the back air outlet 133 is closer to the plane where the back air outlet 133 is located. Similarly, the bottom of the vertical air guide plate 53 farther away from the back air outlet 133 is farther away from the plane where the back air outlet 133 is located.

[0115] In this embodiment, the tops of the multiple vertical air guide plates 53 are horizontally aligned, and the lengths of the multiple vertical air guide plates 53 gradually decrease along the direction from the first side 151 to the second side 152, so that the distance between the bottoms of the multiple vertical air guide plates 53 and the plane where the back air outlet 133 is located gradually increases.

[0116] Further, the outer wall of the back plate 15 is recessed inward to form an air outlet groove for defining the air outlet 50. The back plate 15 includes a groove wall for forming the air outlet groove. Preferably, the refrigerator further includes an air outlet 50 cover plate covering the air outlet groove.

[0117] The groove wall includes a first groove wall 51 and a second groove wall 52 extending upward from two ends of the back air outlet 133 respectively.

[0119] Further, the first groove wall 51 is configured as a vertical groove wall, and the second groove wall 52 includes a guide slope section 521 extending upward from the back air outlet 133, and a guide vertical section 522 extending upward from the guide slope section 521. The guide slope section 521 guides the air discharged from the back air outlet 133 to flow upward, so as to guide the air to flow to the sub-air duct away from the back air outlet 133, so as to improve the uniformity of air flow in each sub-air duct.

[0120] Further, the vertical air guide plate 53 is arranged on the outer wall of the back plate 15. The vertical air guide plate 53 is arranged above the back air outlet 133. The first condenser 64 is arranged on the inner wall of the back plate 15, and at least part of the pipeline of the first condenser 64 is arranged to extend in the same direction as the sub-air duct. At least part of the pipeline of the first condenser 64 is arranged correspondingly on the inner side of the sub-air duct.

[0121] When the first fan 41 is running, the air outside the compressor compartment 11 enters through the air inlet driven by the first fan 41, first cools the compressor 67 of the compressor compartment 11, and then is discharged out of the compressor compartment 11 through the back air outlet 133. The air discharged from the back air outlet 133 flows upward to cool the first condenser 64 on the inner wall of the back panel 15, thereby reusing the air and improving the heat dissipation effect of the refrigerator refrigeration system.

[0122] Combination Figure 8 As shown, the pipeline of the first condenser 64 includes a plurality of vertical segment condenser tubes 641 extending from bottom to top and an arc segment condenser tube 642 connecting two adjacent vertical segment condenser tubes 641 .

[0123] The pipeline of the first condenser 64 is arranged to extend spirally from top to bottom. The total length of the multiple vertical section condenser tubes 641 is much longer than the total length of the multiple arc section condenser tubes 642. Therefore, it is more important to cool down the multiple vertical section condenser tubes 641. Among them, the vertical section condenser tubes 641 are arranged on the inner side of multiple sub-air ducts. The air discharged from the back air outlet 133 flows upward, and the airflow passes through the sub-air duct. Therefore, the vertical section condenser tubes 641 are arranged on the inner side of multiple sub-air ducts, so that the air can be fully reused for the second time, thereby improving the heat dissipation effect of the refrigerator refrigeration system.

[0124] refer to Figure 7 As shown, in a second embodiment of the first fan 41, the first fan 41 is arranged at the back air outlet 133.

The volute includes a volute front wall 411, a volute rear wall 413, an arc-shaped side wall 414 connecting the volute front wall 411 and the volute rear wall 413, and a volute top wall 416. The volute top wall 416 is provided with a top exhaust port 417. The volute front wall 411 is provided with a front air intake port 412 located in the compressor chamber 11. When the first fan 41 is in operation, the air outside the compressor chamber 11 enters through the bottom air inlet 121 on the bottom plate 12, is sucked into the first fan 41 by the front air intake port 412, and then is discharged upward along the outer side of the compressor chamber back plate 13 through the top air exhaust port 417. This allows the compressor chamber 11 to form a heat dissipation mode of bottom air intake and rear air outlet. This allows the compressor chamber 11 to cool and dissipate heat, thereby improving the compression refrigeration effect of the compressor 67.

[0127] Furthermore, the housing 1 also includes a bottom plate 12 for defining the compressor chamber 11, and a bottom air inlet 121 is provided on the bottom plate 12 for connecting the inside and outside of the compressor chamber 11.

This allows the compressor chamber 11 to form a heat dissipation mode of bottom air intake and rear air outlet. This allows the compressor chamber 11 to cool and dissipate heat, thereby improving the compression and refrigeration effect of the compressor 67.

[0128] Furthermore, the housing 1 includes a press chamber support plate 14 extending obliquely upward from the front side of the bottom plate 12 , and a third condenser 66 disposed on the press chamber support plate 14 .

Preferably, a spacing is preset between the vertical bottom plate 123 and the support inclined portion 142, so that the air outside the refrigerator can enter the press chamber 11 through the spacing between the vertical bottom plate 123 and the support inclined portion 142.

[0132] Among them, a bottom air inlet 121 is provided on the horizontal bottom plate 122 and / or the vertical bottom plate 123. The bottom air inlet 121 is provided with a plurality of air inlet holes spaced apart along the left and right directions of the bottom plate 12. When the first fan 41 is running, the air outside the compressor chamber 11 enters through the bottom air inlet 121 on the bottom plate 12 driven by the first fan 41, and cools down the compressor 67 in the compressor chamber 11. In this embodiment, at least two groups of bottom air inlets 121 are respectively provided on the horizontal bottom plate 122 and the vertical bottom plate 123.

[0135] Furthermore, part of the horizontal bottom plate 122 extends downward to form a fixed boss 124. The fixed boss 124 is arranged behind the bottom air inlet 121. The arrangement of the fixed boss 124 facilitates the air outside the refrigerator to enter the compressor chamber 11 through the bottom air inlet 121. The structure is simple and easy to implement.
