[0050] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0051] The terms "including" and "having" and any variations thereof in the present invention are intended to cover non-exclusive inclusions. Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] Figures 1 to 8 A refrigerator provided by a first embodiment of the present invention is shown.

[0053] refer to Figure 1 As shown, the refrigerator includes a box body 1 and a door body. The box body 1 defines a storage space and a press chamber 11. The press chamber 11 is located at the bottom of the box body 1. The door body is used to open or close the storage space. In this embodiment, the door body is defined to be installed on the front side of the box body 1. The box body 1 includes an inner tank that defines a storage space. A compressor 17 is arranged in the press chamber 11.

[0054] The refrigerator of the present invention is preferably a built-in refrigerator, which is used to be embedded in a cabinet or other storage space to save indoor space.

[0055] Combination Figure 2 and Figure 3 As shown, the refrigerator also includes a condensing fan assembly arranged in the compressor chamber 11. The condensing fan assembly includes a condenser 2 and a centrifugal fan 3 installed integrally with the condenser 2. The centrifugal fan 3 accelerates the air using a high-speed rotating impeller, then decelerates and changes the flow direction, and discharges the air from the exhaust port 36 of the centrifugal fan 3. The centrifugal fan 3 is configured to enable the heat in the compressor chamber 11 to be discharged in a timely and effective manner to ensure the refrigeration effect of the refrigerator. The centrifugal fan 3 has the characteristics of strong wind resistance resistance, which ensures that in the use scenario of high wind resistance, the heat dissipation air volume is greatly increased compared with the traditional heat dissipation method.

[0056] The condenser 2 is arranged to be inclined forward from bottom to top, and the angle formed by the front wall of the condenser 2 and the vertical plane is less than 45°.

[0057] The condenser 2 is arranged to be inclined forward from bottom to top, and the angle formed by the front wall of the condenser and the vertical plane is less than 45°. The condensation pipeline of the condenser 2 is arranged to extend and be inclined in the vertical direction. In other words, the condenser 2 is arranged to be inclined downward from front to back. With such an arrangement, the longitudinal installation space of the condenser 2 can be reduced. When the space size of the compressor chamber is fixed, the installation size of the condenser 2 can be increased, the pipeline length of the condenser 2 can be extended, and the air intake at the condenser 2 can be increased under the promotion of the centrifugal fan 3, thereby improving the heat dissipation efficiency of the compressor chamber 11.

[0058] Preferably, the centrifugal fan 3 is arranged at a distance from the rear side of the condenser 2 to ensure that the air passing through the condenser 2 has enough space to enter the centrifugal fan 3 .

[0059] Furthermore, the compressor chamber 11 is connected to the external space below the box body 1 through the air inlet 12 and the air outlet 13 which are arranged side by side in a transverse direction at the bottom of the box body 1. The centrifugal fan 3 causes the air to flow through the compressor 17 through the bottom air inlet 12 and then flow through the condenser 2 to be discharged from the compressor chamber 11, or directly flow through the condenser 2 without passing through the compressor 17 and then flow out of the compressor chamber 11 through the bottom air outlet 13. The transverse direction refers to the left-right direction or the front-back direction. In this embodiment, for the convenience of description, the transverse direction refers to the left-right direction.

[0060] Combined with the bottom air inlet and outlet heat dissipation method in this embodiment, the condenser 2 is arranged to be tilted forward in the direction from bottom to top, so that the condenser 2 can be arranged toward the air inlet 12, thereby increasing the air intake volume at the condenser 2 and improving the heat dissipation efficiency and heat dissipation effect of the compressor chamber 11.

[0061] Combination Figure 4 and Figure 5 As shown, further, the condensing fan assembly also includes a wind tube 4 for fixing the condenser 2, and the wind tube 4 forms a channel 41 that runs through the front and back and is used to accommodate the condenser 2. The channel 41 is extended from the front to the back. The wind tube 4 includes a fixing structure for fixing the condenser 2. Preferably, the side opening of the wind tube 4 is formed with a plurality of blocks 48, and the condenser 2 is fixed to the plurality of blocks 48.

[0062] Combination Figure 6 As shown, the centrifugal fan 3 is fixed to the rear side of the wind tube 4, and the air inlet 35 of the centrifugal fan 3 is connected to the channel 41. By fixing the condenser 2 in the wind tube 4 and the centrifugal fan 3 to the rear side of the wind tube 4, the centrifugal fan 3 and the condenser 2 are installed in an integrated manner, and at the same time, the channel 41 allows all the airflow passing through the condenser 2 to enter the air inlet 35 of the centrifugal fan 3, thereby improving the heat dissipation efficiency of the centrifugal fan 3.

[0063] Further, the centrifugal fan 3 includes a front volute 31, a rear volute 32 fixedly connected to the front volute 31, and an impeller 34. The front volute 31 and the rear volute 32 together form a volute air duct 33. The impeller 34 is arranged in the volute air duct 33, and the air inlet 35 is formed in the front volute 31. Among them, the front volute 31 is fixedly connected to the air cylinder 4.

[0064] In this embodiment, the front volute 31 and the rear volute 32 together form an exhaust port 36 of the centrifugal fan 3 with an opening toward the side. The volute air duct 33 is connected to the passage 41 through the air suction port 35. The volute air duct 33 connects the air suction port 35 with the exhaust port 36.

[0065] Furthermore, the centrifugal fan 3 also includes a motor drivingly connected to the impeller 34. A motor bracket is integrally provided on the front volute 31 or the rear volute 32 for fixing the motor.

[0066] Furthermore, the air cylinder 4 and the front volute 31 are fixedly connected by snap-fitting.

[0067] Reference Figure 5 As shown, specifically, the wind cylinder 4 includes a wind cylinder body 42 and a first limiting rib 43 extending backward from the wind cylinder body 42 , wherein the wind cylinder body 42 and the first limiting rib 43 together form a first limiting groove 45 opening backward.

[0068] The front volute 31 includes a first abutting portion 311 that is limitedly abutted with the first limiting rib 43 along the front-to-back direction, and a first clamping portion 312 that is clamped in the first limiting groove 45. When the first clamping portion 312 is inserted into the first limiting groove 45 through the opening of the first limiting groove 45, the first abutting portion 311 is limitedly abutted with the first limiting rib 43. Thus, the front volute 31 and the air cylinder 4 are limitedly installed. It can be understood that the first clamping portion 312 can be directly fixedly installed with the first limiting groove 45, or it can be only a preliminary positioning installation, and the fixation of the two is achieved through the cooperation of other fixing parts.

[0069] Furthermore, the wind cylinder 4 includes a wind cylinder body 42 and a first buckle 44 formed by extending the wind cylinder body 42 backward.

[0070] Reference Figure 6 As shown, the front volute 31 includes a first clamping portion 313 fixedly clamped with the first clamp 44, wherein the first clamp 44 is provided with a first clamping groove for the first clamping portion 313 to be clamped in. Through such a configuration, the purpose of fixed connection between the front volute 31 and the air cylinder 4 can be further achieved.

[0072] Specifically, the front volute 31 includes a front volute body 314 and a second limiting rib 315 extending backward from the front volute body 314 , wherein the front volute body 314 and the second limiting rib 315 together form a second limiting groove 316 opening backward.

[0073] Reference Figure 5 , Figure 6 As shown, the rear volute 32 includes a second abutting portion 321 that is limitedly abutted with the second limiting rib 315 along the front-to-back direction, and a second clamping portion 322 that is clamped in the second limiting groove 316. When the second clamping portion 322 is clamped into the second limiting groove 316, the second abutting portion 321 is limitedly abutted with the second limiting rib 315 at the same time. It can be understood that the second clamping portion 322 can be directly fixedly installed with the second limiting groove 316, or it can be only preliminarily positioned and installed, and the two can be fixed by the cooperation of other fixing parts.

[0074] Furthermore, the front volute 31 includes a front volute body 314 and a second buckle 317 formed by the front volute body 314 extending backward.

[0075] The rear volute 32 includes a second clamping portion 323 fixedly clamped with the second clamp 317, wherein the second clamp 317 is provided with a second clamping groove for the second clamping portion 323 to be clamped in. Through such a configuration, the purpose of fixedly connecting the front volute 31 and the rear volute 32 can be further achieved.

[0076] Reference Figure 3 As shown, further, the housing 1 includes a press chamber back plate 15 for defining the press chamber 11. The rear volute 32 extends backward to form a first lug 324 fixedly connected to the press chamber back plate 15, and a first fastener that fixes the first lug 324 to the press chamber back plate 15. The first lug 324 of the rear volute 32 is fixed to the press chamber back plate 15 to achieve the purpose of installing the integrated condensing fan assembly formed by the centrifugal fan 3 and the condenser 2 on the press chamber back plate 15 as a whole.

[0077] Reference Figure 4 As shown, an inclined support portion 46 is provided in the air duct 4 and is located at the bottom of the condenser 2. The inclined support portion 46 has a support surface that is inclined upward in a direction from front to rear.

[0078] Preferably, the inclination angle a between the front wall of the condenser 2 and the vertical plane is 10° to 20°.

[0079] Furthermore, the pivot centerline of the centrifugal fan 3 is extended from the front to the rear. The air inlet 35 of the centrifugal fan 3 is arranged forward. The front side of the centrifugal fan 3 sucks air, so that all the airflow of the condenser 2 enters the centrifugal fan 3 through the air inlet 35, thereby improving the heat dissipation efficiency of the centrifugal fan 3.

[0080] Furthermore, the compressor 17 and the condensing fan assembly are arranged side by side laterally along the bottom of the housing 1 .

[0081] The air inlet 12 is disposed on the front side of the condenser 2, and the air outlet 13 is disposed on the front side of the compressor 17. One side of the condenser 2 is defined as the left side, and one side of the compressor 17 is defined as the right side.

[0082] The air inlet 35 of the centrifugal fan 3 is arranged toward the condenser 2, and the air outlet 36 of the centrifugal fan 3 is arranged toward the compressor 17. The air inlet 35 is formed in the front volute 31. The front volute 31 and the rear volute 32 jointly form the air outlet 36.

[0083] Thus, a heat dissipation air path is formed, which includes the left side of the front of the refrigerator - the air inlet space on the left side of the bottom of the refrigerator - the condenser 2 - the channel 41 - the centrifugal fan 3 - the compressor 17 - the air outlet space on the right side of the bottom of the refrigerator - the heat dissipation air path on the right side of the front of the refrigerator, so as to improve the heat dissipation efficiency of the compressor compartment 11.

[0084] Reference Figure 2 As shown, further, the box body 1 includes a bottom plate 14, a press chamber back plate 15, and a press chamber support plate 16 extending upwardly from the front side of the bottom plate 14. The press chamber back plate 15 is a fully enclosed design, that is, no air inlet 12 and no air outlet 13 are provided.

[0085] The press chamber support plate 16 includes a support bottom 161 adjacent to the front side of the bottom plate 14. The press chamber support plate 16 also includes a support inclined portion 162 extending obliquely backward and upward from the support bottom 161, and a support top portion 163 extending horizontally backward from the support inclined portion 162 to the back plate of the press chamber.

[0086] The bottom plate 14 , the press chamber rear plate 15 , the support inclined portion 162 and the support top portion 163 together define the press chamber 11 .

[0087] Furthermore, a gap is preset between the support bottom 161 and the bottom plate 14, the gap on one side forms the air inlet 12, and the gap on the other side forms the air outlet 13. A wire mesh or grille is provided at the gap to protect the air inlet 12 and the air outlet 13.

[0088] Furthermore, an air inlet 12 is disposed on one side of the bottom plate 14 , and an air outlet 13 is disposed on the other side of the bottom plate 14 .

[0089] Furthermore, the dimension of the air inlet 12 in the front-to-back direction is 60-80 mm, so as to further increase the air intake volume and improve the heat dissipation efficiency of the compressor chamber 11.

[0090] The dimension of the air outlet 13 in the front-to-back direction is 60-80 mm, so as to ensure that the airflow of the compressor chamber 11 can flow out smoothly, so as to improve the smoothness of heat dissipation.

[0091] Furthermore, the distance between the condenser 2 and the centrifugal fan 3 is 30-60 mm, thereby further ensuring the heat dissipation efficiency and ensuring that the airflow passing through the condenser 2 can all enter the centrifugal fan 3 .

[0092] Furthermore, the refrigerator further comprises a bottom plate 14 for defining the press chamber 11, an evaporation dish 51 disposed on the bottom plate 14, and a support plate 52 disposed on the top of the evaporation dish 51. The support plate 52 is fixed to the top of the evaporation dish 51 by fasteners, so that the two form a whole.

[0093] The air duct 4 is arranged on the top of the support plate 52. The condenser 2 and the centrifugal fan 3 are first assembled into an integrated condensing fan assembly through the air duct 4, and then fixedly connected to the support plate 52. Combined with the above-mentioned setting of fixing the first lug 324 of the rear volute 32 on the rear back plate 15 of the compressor chamber, the purpose of installing the integrated condensing fan assembly formed by the centrifugal fan 3 and the condenser 2 on the rear back plate 15 of the compressor chamber and the support plate 52 is achieved. The condensing fan assembly is fixed more stably, reliably and firmly.

[0094] Reference Figure 6 As shown, further, the bottom of the air duct 4 extends downward to form a hook portion 47 that is engaged with the support plate 52. The support plate 52 is vertically penetrated with a through hole for the hook portion 47 to be engaged. The hook portion 47 is fixedly engaged with the through hole by snapping and fixing, so as to realize the fixed engagement of the two, which has the advantages of easy installation and easy positioning.

[0095] Furthermore, the centrifugal fan 3 includes a front volute 31 and a rear volute 32 fixedly connected to the front volute 31 .

[0096] The rear volute 32 extends downward to form a second lug 325 fixedly connected to the support plate 52 and a second fastener that fixes the second lug 325 to the support plate 52. The second lug 325 and the second fastener further improve the connection strength between the centrifugal fan 3 and the support plate 52.

[0097] Furthermore, the condenser 2 is configured as a microchannel condenser. The air in the air inlet space from the left side of the front of the refrigerator to the left side of the bottom of the refrigerator can pass through the microchannel condenser and then be completely sucked in by the centrifugal fan 3 through the channel to maximize the heat dissipation efficiency.

[0098] The pipeline of the microchannel condenser is extended backward, and the pipeline of the microchannel condenser passes through the centrifugal fan 3 backward. The welding points between the pipeline of the microchannel condenser and the other refrigerant pipelines are all located at the rear side of the centrifugal fan 3 to facilitate welding connection. Specifically, the welding point between the pipeline of the microchannel condenser and the connecting pipeline of the compressor is located at the rear side of the centrifugal fan 3, and the welding point between the pipeline of the microchannel condenser and the connecting pipeline of the throttling component is located at the rear side of the centrifugal fan 3.

[0099] Furthermore, the box body 1 including the side walls symmetrically arranged on the left and right sides of the box body 1 and the rear back plate 15 of the press chamber are of fully enclosed design, that is, the air inlet and outlet 13 are not arranged.

[0100] Combination Figure 3 As shown, further, the refrigerator also includes a wind shield strip 6 arranged on the lower surface of the bottom wall of the box body 1, and the wind shield strip 6 includes a first wind shield section 61 arranged between the air inlet 12 and the air outlet 13, and a second wind shield section 62 extending laterally from the rear end of the first wind shield section 61.

[0101] Combination Figure 7 and Figure 8 As shown, the second wind shielding section 62 extends laterally toward one side of the air inlet 12 or toward one side of the air outlet 13. When the refrigerator is placed on a support surface, the space between the bottom wall of the refrigerator and the support surface is laterally separated to prevent the airflow in the space on the left side of the wind shielding strip 6 from flowing in parallel with the airflow in the space on the right side of the wind shielding strip 6.

[0102] The second wind shielding section 62 is disposed at the rear side of the air inlet 12 or the air outlet 13 .

[0103] Specifically, when the second wind shielding section 62 is disposed at the rear side of the air inlet 12, it is ensured that the air on the left side of the bottom of the refrigerator enters the compressor compartment 11 only through the air inlet 12, so as to prevent the air on the left side of the bottom of the refrigerator from entering the space behind the air outlet 13. The air intake of the air inlet 12 is increased, the air intake efficiency is improved, and the heat dissipation effect of the compressor compartment 11 is improved.

[0104] Specifically, when the second wind shielding section 62 is disposed at the rear side of the air outlet 13 , the air in the compressor compartment 11 is prevented from flowing toward the rear side of the air outlet 13 , thereby ensuring that the air in the compressor compartment 11 flows forward through the air outlet 13 .

[0105] Furthermore, the first wind shield section 61 is inclined from the back to the front toward the direction of the air outlet 13. It is defined that the air inlet 12 is arranged on the left side, and the air outlet 13 is arranged on the right side. When the refrigerator is placed on a supporting surface, the airflow on the left side of the bottom of the refrigerator follows the inclined first wind shield section 61 through the air outlet 13 and enters the compressor chamber 11.

[0106] Specifically, the front end of the first wind shielding section 61 is arranged at the front edge of the bottom wall of the box body 1, and the front edge of the bottom wall of the box body 1 includes a first section and a second section which are respectively arranged opposite to the air inlet 12 and the air outlet 13.

[0107] The angle formed by the first wind shielding section 61 and the first section is an acute angle.

[0108] Furthermore, the first wind shielding section 61 is transitionally connected to the second wind shielding section 62 via an arc-shaped connecting section.

[0109] Compared with the prior art, the refrigerator provided by the present invention forms an integrated condensing fan assembly through the condenser 2 and the condenser 2, which is convenient for modular and systematic installation. The centrifugal fan 3 is arranged at intervals on the rear side of the condenser 2 to ensure that the air passing through the condenser 2 can have enough heat dissipation space to enter the centrifugal fan 3. The centrifugal fan 3 causes the air to flow through the bottom air inlet 12, first through the compressor 17, and then through the condenser 2 to be discharged from the compressor compartment 11, or directly through the condenser 2 without passing through the compressor 17 and then through the bottom air outlet 13 to be discharged from the compressor compartment 11. The heat dissipation path is reasonable, which is convenient for better heat dissipation in the compressor compartment 11, and has the advantages of easy installation, large heat dissipation space, good heat dissipation effect and high heat dissipation efficiency.

[0110] Fig. 9 A refrigerator provided by a second embodiment of the present invention is shown.

[0111] The difference between this embodiment and the first embodiment is that the first wind shielding section 61 of the first embodiment is inclined from the rear to the front toward the direction of the air outlet 13. The wind shielding strip 6 of the second embodiment includes an arc segment arranged at the front end. The components in the second embodiment with the same reference numerals as those in the first embodiment have the same functions and are not further described here.

[0112] The refrigerator includes a box body 1, and a storage space and a press chamber 11 are defined in the box body 1. The press chamber 11 is located at the bottom of the box body 1, and a compressor 17 is provided in the press chamber 11. The press chamber 11 is connected to the external space below the box body 1 through an air inlet 12 and an air outlet 13 arranged side by side transversely at the bottom of the box body 1. In the second embodiment, the transverse direction refers to the left and right direction. For the convenience of description, it is defined that the air inlet 12 is arranged on the left side, and the air outlet 13 is arranged on the right side.

[0113] The refrigerator further includes a condensing fan assembly disposed in the compressor compartment 11 and a wind shield 6 disposed on the lower surface of the bottom wall of the housing 1 and extending in the front-to-back direction.

[0114] The condensing fan assembly includes a condenser 2 and a centrifugal fan 3 installed integrally with the condenser 2 .

[0115] The windshield strip 6 is arranged between the air inlet 12 and the air outlet 13. When the refrigerator is placed on a support surface, the space between the bottom wall of the refrigerator and the support surface is separated horizontally to prevent the airflow in the space on the horizontal left side of the windshield strip 6 from flowing in parallel with the airflow in the space on the horizontal right side of the windshield strip 6. The space on the left side of the windshield strip 6 forms the air inlet space of the air inlet 12, and the space on the right side of the windshield strip 6 forms the air outlet space of the air outlet 13, thereby forming a heat dissipation air path of the left side of the front of the refrigerator - the air inlet space on the left side of the bottom of the refrigerator - the compressor compartment 11 - the air outlet space on the right side of the bottom of the refrigerator - the heat dissipation air path of the right side of the front of the refrigerator, so as to improve the heat dissipation efficiency of the compressor compartment 11.

[0116] Reference Fig. 9 As shown, the windshield strip 6 includes an arc segment 611 arranged at the front end. The arc segment 611 is extended from the front to the rear, and the arc segment 611 is arranged as the front end of the windshield strip 6. The guide gas is distributed and guided along the arc segment 611, so that the uniformity of the flow of the airflow is improved, and the flow rate and flow direction of the airflow also become more uniform, playing a role of smooth guidance. This prevents the airflow in the space on the left side from flowing in parallel with the airflow in the space on the right side of the windshield strip 6.

[0117] Further, the windshield strip 6 includes a first windshield section 61 disposed between the air inlet 12 and the air outlet 13, and a second windshield section 62 extending laterally from the rear end of the first windshield section 61. The second windshield section 62 extends laterally toward one side of the air inlet 12 or toward one side of the air outlet 13. In other words, the first windshield section 61 extends in the front-to-back direction, and the second windshield section 62 extends from the first windshield section 61 to the right or to the left.

[0118] The arc segment 611 is formed at the front end of the first wind shielding segment 61. Preferably, the arc segment 611 is connected to the front edge of the bottom wall of the box body 1.

[0119] The second wind shielding section 62 is disposed at the rear side of the air inlet 12 or the air outlet 13 .

[0120] Specifically, when the second wind shielding section 62 is disposed at the rear side of the air inlet 12, it is ensured that the air on the left side of the bottom of the refrigerator enters the compressor compartment 11 only through the air inlet 12, so as to prevent the air on the left side of the bottom of the refrigerator from entering the space behind the air outlet 13. The air intake of the air inlet 12 is increased, the air intake efficiency is improved, and the heat dissipation effect of the compressor compartment 11 is improved.

[0121] Specifically, when the second wind shielding section 62 is disposed at the rear side of the air outlet 13 , the air in the compressor compartment 11 is prevented from flowing to the rear side of the air outlet 13 , and the air in the compressor compartment 11 is ensured to flow forward through the air outlet 13 , so as to improve the heat dissipation effect of the compressor compartment 11 .

[0122] Furthermore, the first wind shielding section 61 also includes a straight section 612 extending backward from the rear end of the arc section 611. After the airflow is guided by the arc section 611 of the front section, the straight section 612 can shorten the moving track of the airflow to improve the heat dissipation effect of the compressor chamber 11. Preferably, the length of the straight section 612 is much greater than the length of the straight section 612 to shorten the moving track of the airflow to improve the heat dissipation effect of the compressor chamber 11.

[0123] The rear end of the straight section 612 extends laterally to form a second wind shielding section 62 .

[0124] Furthermore, the arc segment 611 protrudes toward the air inlet 12. The guiding air flows along the arc segment 611 toward the air inlet space of the air inlet 12, so that the flow uniformity of the airflow is improved, and the airflow is smoothly guided, so as to increase the air intake of the air inlet 12 and prevent the airflow in the space on the left side from flowing in parallel with the airflow in the space on the right side of the wind shield strip 6.

[0125] Preferably, the curvature of the arc segment 611 is 45° to 55°.

[0126] Compared with the prior art, the refrigerator provided by the present invention forms an integrated condensing fan assembly through the condenser 2 and the condenser 2, which is convenient for modular and systematic installation, and the wind shield 6 separates the air inlet space of the air inlet 12 and the air outlet space of the air outlet 13 to avoid the cross-flow of air in the air inlet space and the air outlet space. The arc segment 611 is set as the front end of the wind shield 6, and the guide gas is distributed and guided along the arc segment 611, so that the flow uniformity of the airflow is improved, and the flow rate and flow direction of the airflow also become more uniform, which plays a role of smooth guidance, and has the effects of easy installation, good outflow and return air diversion effect, and uniform guidance.

Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
