Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0037] In the related art, the refrigerator can be embedded in the cabinet, but such arrangement can result in low heat dissipation efficiency of the refrigerator.

The fan air outlet 3313 communicates the air guide channel 114 and the air outlet channel 3312. As shown in FIG. 10, the fan 33 includes a centrifugal fan 332. The centrifugal fan 332 is arranged in the fan cavity 3311. The fan is arranged behind the condenser and the fan is a centrifugal fan, so that the flow direction of the air can be changed, the space in the compressor cavity can be fully utilized, and the occupation of the refrigeration compartment is reduced.

[0082] As shown in FIGS. 6 and 8, the fan inlet 3314 is formed on the volute 331. The fan inlet 3314 is located on the front side of the volute 331. The fan inlet 3314 communicates the fan cavity 3311 and the compressor cavity 113. The condenser 31 is located in front of the fan 33. The condenser 31 is located in front of the volute 331, so that the fan inlet 3314 is located behind the condenser 31, so that the air after heat exchange with the condenser 31 enters the fan cavity 3311.

[0083] In some embodiments, referring to FIGS. 8, 9, 10 and 11, the volute 331 includes an air outlet plate 3315 for enclosing the air outlet channel 3312. The air outlet plate 3315 is located behind the air outlet channel 3312. The air outlet plate 3315 is provided with an air outlet surface 33151 close to one side of the air outlet channel 3312. In the front-rear direction of the cabinet 1, the top end of the air outlet surface 33151 is located on the side away from the bottom end of the air outlet surface 3315 to the front end of the cabinet 1.

[0084] The air outlet surface 33151 can include a first air outlet surface 331511. In the front-rear direction of the cabinet 1, the top end of the first air outlet surface 331511 is located on the side away from the bottom end of the first air outlet surface 331511 to the front end of the cabinet 1. The first air outlet surface 331511 can be an inclined plane.

[0085] The first air outlet surface 331511 has a first profile line parallel or intersecting the first plane, and the tangent of the first profile line and the front-rear direction of the cabinet 1 forms a first included angle a, the first included angle a is an acute angle, so that the first air outlet surface guides the air upward and backward, which is beneficial to the air flowing out from the rear of the refrigerator. In this application, the first air outlet surface 331511 and the front-rear direction of the cabinet 1 can form a first included angle a, and the first included angle a is an acute angle.

[0086] In some embodiments, the second included angle β≥ the first included angle a. The air guide channel 114 and the air outlet channel 3312 are arranged to guide the air upward and backward. Since the first air guide surface 14111 is located on the front side of the air guide channel, the first air guide surface 14111 guides the air on the front side, and the second included angle cannot be too small, which is beneficial to upward air guide. Since the first air outlet surface 331511 is located on the rear side of the air outlet channel 3312, the first air outlet surface 331511 guides the air on the rear side, and the first included angle cannot be too large, which is beneficial to backward air guide. The second included angle β≥ the first included angle a can reduce the air outlet pressure and reduce the vortex.

[0087] In some embodiments, referring to FIG. 12, the compressor 34 is disposed in the compressor cavity 113. The refrigerator can include an evaporating tray 36. The evaporating tray 36 is disposed in the compressor cavity 113. The evaporating tray 36 is formed with a first evaporation cavity 361 and a second evaporation cavity 362 that are in communication with each other. The first evaporation cavity 361 is located at one side of the compressor 34 along the width direction of the cabinet 1. The second evaporation cavity 362 is located at the front side of the compressor 34. The front end of the first evaporation cavity 361 is located behind the front end of the second evaporation cavity 362.

[0088] As shown in FIG. 6, the compressor cavity 113 can include an air inlet passage 1131. The air inlet passage 1131 is located at the front side of the first evaporation cavity 361, and the air inlet passage 1131 is located at one side of the second evaporation cavity 362 along the width direction of the cabinet 1. The second evaporation cavity 362 is formed in the evaporating tray 36, which can make full use of the space at the front side of the compressor 34 and the rear side of the first inner tank 121, thereby increasing the volume of the evaporating tray 36 and preventing condensate from overflowing the evaporating tray 36.

[0089] In some embodiments, referring to FIGS. 8, 9, 10 and 11, the minimum thickness of the air outlet passage 3312 in the front-rear direction of the cabinet 1 is a first size T1. The maximum thickness of the centrifugal fan 332 in the front-rear direction of the cabinet 1 is a second size T2, and the first size T1≥ the second size T2. In this way, the air outlet passage 3312 can avoid shielding the air outlet at the centrifugal fan 332, thereby improving the air outlet volume.

[0090] In some embodiments, as shown in FIGS. 6 and 10, the volute 331 can include a volute front plate 3316 located at the front side of the volute 331. The volute 331 can include a volute rear plate 3317 located at the rear side of the volute 331. The volute front plate 3316 is formed with a fan air inlet 3314, as shown in FIG. 8.

[0091] As shown in FIG. 10, the volute 331 can include a fan surrounding plate 3318. The fan surrounding plate 3318 is disposed at one side of the volute front plate 3316 close to the volute rear plate 3317. The fan surrounding plate 3318 is connected to the volute front plate 3316. The fan surrounding plate 3318 surrounds the outside of the fan air inlet 3314 and the centrifugal fan 332, as shown in FIG. 11. The minimum distance between the fan surrounding plate 3318 and the air outlet plate 3315 in the front-rear direction of the cabinet 1 is a third size T3. The maximum thickness of the centrifugal fan 332 in the front-rear direction of the cabinet 1 is a second size T2, and the first size W3≥ the second size T2. In this way, the fan surrounding plate 3318 and the air outlet plate 3315 can avoid shielding the air outlet at the centrifugal fan 332, thereby improving the air outlet volume.

[0092] Referring to FIGS. 13 and 14, the present application also proposes a refrigeration system. The refrigeration system can include the refrigerator in the above embodiments. The refrigeration system also includes a cabinet 4. The refrigerator is arranged in the cabinet 4. An installation space is formed in the cabinet 4. The refrigerator is arranged in the installation space.

[0093] Referring to FIGS. 13 and 14, the refrigerator and the cabinet 4 form a first heat dissipation passage 41 located at the rear of the refrigerator. The cabinet 4 includes a cabinet back plate 42 located at the back of the cabinet 4. The cabinet back plate 42 is located at the rear of the refrigerator. The refrigerator and the cabinet back plate 42 are arranged in a spaced manner to form the first heat dissipation passage 41 between the refrigerator and the cabinet back plate 42.

[0094] Referring to FIGS. 13 and 14, the front of the cabinet 4 is formed with a heat dissipation air inlet 43 and a heat dissipation air outlet 44. The heat dissipation air inlet 43 is located at the bottom end of the refrigerator away from the top end of the refrigerator. The heat dissipation air outlet 44 is located at the top end of the refrigerator away from the bottom end of the refrigerator. The heat dissipation air inlet 43 is in communication with the air inlet 111 to allow air to enter the compressor cavity 113. The heat dissipation air outlet 44 is in communication with the first heat dissipation passage 41 to allow air to exit the cabinet 4.

[0095] Specifically, the bottom end of the cabinet 4 is formed with a second heat dissipation passage 45 located below the refrigerator. The heat dissipation air inlet 43 is located at the front end of the second heat dissipation passage 45. The heat dissipation air inlet 43 is in communication with the second heat dissipation passage 45. The second heat dissipation passage 45 is in communication with the air inlet 111 to allow air entering the second heat dissipation passage 45 from the heat dissipation air inlet 43 to enter the compressor cavity 113.

[0096] Referring to FIGS. 13 and 14, the top end of the cabinet 4 is provided with a third heat dissipation passage 46. The third heat dissipation passage 46 is located at the side of the cabinet 1 away from the bottom end of the cabinet 1. The third heat dissipation passage 46 is in communication with the first heat dissipation passage 41. The heat dissipation air outlet 44 is located at the front end of the third heat dissipation passage 46. The heat dissipation air outlet 44 is in communication with the third heat dissipation passage 46 to allow air from the air outlet 112 to flow out of the heat dissipation air outlet 44 through the first heat dissipation passage 41 and the third heat dissipation passage 46. In this way, the refrigerator embedded in the cabinet 4 can be better cooled, and the air guiding passage can guide air upward as much as possible while reducing the occupation of the air guiding passage to the rear side space of the first evaporator, and there is enough space to fill the temperature insulation layer, so that the temperature insulation layer at the rear side of the first evaporator is thick enough, and the phenomenon of serious condensation at the air guiding passage and the air outlet can be avoided.

[0097] In addition, in the related art, when the refrigerator is embedded in the cabinet, the condenser of the refrigerator is mostly an external condenser or a bottom-mounted condenser. The conventional bottom-mounted condenser is mostly right-in and left-out, that is, the air is taken in from the right side at the back of the refrigerator and is discharged from the left side. When the refrigerator is installed in the cabinet, the effect achieved by the commonly used fan and the setting mode of the fan is greatly reduced because the use scene of the refrigerator is very narrow, the ordinary fan cannot change the direction of the suction and discharge of the hot air, and part of the hot air is blown to the wallboard of the cabinet. After the hot air is blown to the wallboard, it is bounced back to the chamber inside the refrigerator, thereby greatly reducing the heat dissipation efficiency.

[0098] In the embodiments of the present application, a refrigerator is also provided. The refrigerator can effectively discharge the heat generated by the compressor and the condenser through the setting of the accommodating cavity and the vent, thereby avoiding local overheating of the refrigerator. The design of the fan and the air outlet in the refrigerator according to the present application can ensure smooth air circulation, thereby improving the heat dissipation effect. The design of the sealing element in the refrigerator according to the present application effectively separates the vent and the outlet of the air outlet, thereby preventing the backflow of hot air into the refrigerator and ensuring the efficient operation of the heat dissipation system. At the same time, the sealing element separates the high air pressure area generated by the fan and the low air pressure area outside the refrigerator, thereby utilizing the narrow space formed between the refrigerator and the cabinet and utilizing the siphon effect generated thereby. As a result of the fact that hot air is lighter than cold air and the effect of air pressure, the hot air can be accelerated to spread upward, thereby strengthening the air circulation, improving the heat dissipation efficiency, and reducing the condensation temperature. In this way, the working load of the compressor can be reduced, thereby reducing the energy consumption and achieving the energy saving effect. Due to the design of the fan and the air outlet, the hot air can be effectively discharged, the working load of the compressor is reduced, and the working noise of the compressor in the refrigerator is reduced, thereby providing a good user experience.

[0099] Specifically, with reference to FIGS. 15 to 19, the refrigerator provided in the embodiments of the present application includes a cabinet 1. The rear side of the cabinet 1 can be provided with an accommodating cavity 110. It can be understood that the cabinet 1 is the main structure of the refrigerator and is used to store food and other articles. The accommodating cavity 110 can be used to hold the related refrigeration working components of the refrigerator and provides a space for discharging hot air for heat dissipation of the related refrigeration working components.

[0100] The refrigerator can further include a cover plate 120, which can be arranged on the rear side of the cabinet 1 and is used to at least close the accommodating cavity 110. By arranging the cover plate 120, the working parts in the accommodating cavity 110 can be protected.

[0101] The cover plate 120 can be provided with a vent 1210, which can be in communication with the accommodating cavity 110. By arranging the accommodating cavity 110 and the vent 1210, the heat generated in the accommodating cavity can be effectively discharged, thereby avoiding local overheating of the refrigerator.

[0102] The refrigerator can further include a compressor 200 disposed in the accommodation cavity 110, as shown in FIG. 18. It should be understood that the compressor 200 is a core component of the refrigerator refrigeration system, and its main function is to compress the refrigerant and make the refrigerant circulate, thereby achieving the refrigeration effect.

[0103] The refrigerator can further include a condenser 300 disposed in the accommodation cavity 110. The condenser 300 is in communication with the compressor 200.

[0104] It should be understood that the condenser 300 is an important component in the refrigerator refrigeration system, and its main function is to cool and condense the high-temperature and high-pressure gaseous refrigerant discharged by the compressor 200 into liquid refrigerant. The condenser 300 receives high-temperature and high-pressure gaseous refrigerant from the compressor 200. These gaseous refrigerants are compressed in the compressor, so that the temperature and pressure of the refrigerant are significantly increased to generate high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows in the pipeline of the condenser 300, it exchanges heat with the surrounding air. The condenser 300 transfers the heat of the refrigerant to the surrounding air through the cooling fins, so that the refrigerant is gradually cooled. As the temperature of the refrigerant decreases, the gaseous refrigerant gradually condenses into liquid refrigerant, which is called condensation.

[0105] The refrigerator can further include a fan 400 disposed in the accommodation cavity 110. The air inlet of the fan 400 can be in communication with the accommodation cavity 110.

[0106] The refrigerator can further include an exhaust air passage 500. The first section of the exhaust air passage 500 can be in communication with the air outlet of the fan 400, and the second section 502 of the exhaust air passage 500 can be located outside the accommodation cavity 110.

[0107] The design of the fan 400 and the exhaust air passage 500 ensures smooth air circulation, thereby improving the heat dissipation effect.

[0108] As shown in FIGS. 20 and 21, the refrigerator can further include a sealing member 600 disposed on the surface of the cover plate 120 away from the accommodation cavity 110. The surface of the sealing member 600 away from the cover plate 120 is used to abut against the cabinet. The sealing member 600 is used at least to separate the ventilation opening 1210 and the second section 502 of the exhaust air passage 500. In other words, the sealing member 600 is disposed between the cabinet and the cover plate 120.

[0109] The design of the sealing member 600 effectively separates the ventilation opening 1210 and the outlet of the air exhaust duct 500, preventing the hot air from flowing back into the refrigerator, and ensuring the efficient operation of the heat dissipation system. At the same time, the sealing member 600 separates the high air pressure area generated by the fan 400 and the low air pressure area outside the refrigerator, so that the narrow space formed between the refrigerator and the cabinet can be utilized, and the siphon effect can be utilized. Thus, due to the effect of the wind pressure and the fact that hot air is lighter than cold air, the hot air can be accelerated to spread upward, thereby strengthening the air circulation, improving the heat dissipation efficiency, and reducing the condensation temperature. In this way, the working load of the compressor 200 can be reduced, thereby reducing the energy consumption and achieving the energy-saving effect. Since the design of the fan 400 and the air exhaust duct 500 can effectively exhaust hot air, the working load of the compressor 200 is reduced, thereby reducing the working noise of the compressor 200 and improving the user experience.

[0110] In some possible embodiments, the air exhaust duct 500 can be arranged above the containing cavity 110, and the second section 502 of the air exhaust duct 500 extends upward in the vertical direction. Since the second section of the air exhaust duct 500 extends upward in the vertical direction, the hot air can be smoothly exhausted from the top of the refrigerator through the action of the fan 400 and natural convection, thereby making the heat dissipation path more smooth, which utilizes the physical characteristics of the hot air rising, reduces the retention of hot air in the narrow space, and thereby improves the heat dissipation efficiency.

[0111] In the present application, by arranging the second section 502 of the air exhaust duct 500 to extend in the vertical direction, the hot air can be directly exhausted upward, reducing the phenomenon that the air bounces back after hitting the wallboard in the narrow space in the prior art, thereby improving the heat dissipation efficiency. Arranging the air exhaust duct 500 above the containing cavity 110 and extending in the vertical direction does not occupy the effective storage space inside the refrigerator, and at the same time, this design does not significantly affect the appearance of the refrigerator, which is suitable for the use scenario that the refrigerator is embedded in the cabinet. In addition, since the hot air generated in the refrigerator has a small density, the hot air is generally located at the upper layer of the containing cavity 110, so that the air exhaust duct 500 above the containing cavity 110 can accurately suck the hot air.

[0112] Referring to FIG. 20, in some possible embodiments, the first end of the air exhaust duct 500 is the air outlet of the fan 400. When the air exhaust duct 500 is cut by a horizontal plane, the cross-sectional area of the second section of the air exhaust duct 500 gradually decreases in the direction from bottom to top. Although only one inclined air duct part 503 is shown as the second section 502 of the air exhaust duct 500 in FIG. 20, it should be understood that the air exhaust duct 500 is a channel, and the second section 502 of the air exhaust duct 500 is surrounded by the air duct part 503 and the rear plate 131 (as shown in FIGS. 15 and 16) of the cabinet 1, or surrounded by the air duct part 503 and the outer wall of other parts inside the cabinet 1.

[0113] In the present application, the cross-sectional area of the second section 502 of the air exhaust duct 500 gradually decreases in the downward direction. This arrangement helps to accelerate air flow. Specifically, according to Bernoulli's principle, the flow rate of a fluid increases and the pressure decreases when the fluid flows through a converging pipe. When air enters the second section 502 of the air exhaust duct 500 from the lower part, the air flow rate is low due to the larger cross-sectional area. As the air flows upward, the cross-sectional area of the second section 502 of the air exhaust duct 500 gradually decreases, and the air flow rate gradually increases, thereby effectively exhausting hot air and improving heat dissipation efficiency. Bernoulli's principle states that the total mechanical energy of a fluid on a streamline is constant, neglecting viscosity and compressibility. This means that there is a balance between the velocity, pressure, and height of the fluid. When the fluid velocity increases, the dynamic pressure increases, and to maintain the conservation of total energy, the static pressure must decrease. Conversely, when the fluid velocity decreases, the dynamic pressure decreases, and the static pressure increases.

[0114] In some possible embodiments, the sealing member 600 can extend in the horizontal direction. In the horizontal direction, the length of the sealing member 600 can be equal to the length of the cover plate 120. The extension of the sealing member 600 in the horizontal direction and the equal length of the sealing member 600 to the length of the cover plate can ensure the sealing effect between the refrigerator and the cabinet, effectively control the discharge path of hot air, and generate high and low wind pressure areas inside the refrigerator, thereby accelerating the discharge of hot air from the gap between the refrigerator and the cabinet.

[0115] In some possible embodiments, the second section 502 of the air exhaust duct 500 can be located above the sealing member 600, and the air exhaust duct 500 is close to the first end 601 of the sealing member 600 in the length direction, as shown in FIGS. 21 and 22.

[0116] By using the above technical solutions, hot air can be discharged from the inside of the refrigerator through the air exhaust duct 500, avoiding the mixing of hot air with cold air in the environment of the refrigerator, and avoiding the influence on the discharge efficiency.

[0117] The ventilation opening 1210 can be located below the sealing member 600, and the ventilation opening 1210 is close to the second end 602 of the sealing member 600 in the length direction.

[0118] By isolating the hot air generated in the containing cavity 110 from the cold air in the environment of the refrigerator by the sealing member 600, high and low wind pressure areas can be generated inside the refrigerator, thereby accelerating the discharge of hot air from the gap between the refrigerator and the cabinet.

[0119] In some possible embodiments, at least part of the condenser 300 in the containing cavity 110 can be directed toward the ventilation opening 1210, and the condenser 300 is close to the second end 602 of the sealing member 600 relative to the compressor 200.

[0120] In use, the fan 400 draws air from outside the refrigerator into the receiving cavity 110 from the vent 1210 of the cover plate 120. The condenser 300 inside the receiving cavity 110 exchanges heat with the air, increasing the temperature of the air entering from outside the refrigerator, and turning it into hot air. The hot air enters the fan 400 from the air inlet, and is discharged from the second end of the fan 400, into the gap between the back plate 131 of the air conditioner and the cabinet. Since the refrigerator parts below the seal 600 are isolated from the cabinet, and the refrigerator parts above the seal 600 form a channel for the hot air, the hot air can be discharged upwards by the siphon effect. In addition, due to the fact that hot air is lighter than cold air and the effect of wind pressure, the hot air accelerates to spread upwards, so that the hot air is smoothly discharged upwards along the gap between the refrigerator and the cabinet, effectively improving the heat dissipation effect.

[0121] The upper part of the condenser 300 is arranged to face the upper vent 1210, which optimizes the position of the condenser 300 and the air flow path, reduces the rebound effect of the hot air after encountering the cabinet, and thus improves the heat dissipation efficiency.

[0122] Referring to FIGS. 21 to 23, in some possible embodiments, the seal 600 can include a base 610 and a sealing portion 620.

[0123] The base 610 can be fixedly connected with the cover plate 120. The sealing portion 620 can be arranged on the base 610. The sealing portion 620 can protrude from the surface of the base 610. The surface of the sealing portion 620 facing away from the cover plate 120 is used to abut against the cabinet.

[0124] By designing the base 610 to be fixedly connected with the cover plate 120, the stable installation of the seal can be ensured. The sealing portion 620 abuts against the cabinet, thereby forming an effective seal between the refrigerator and the cabinet, and effectively controlling the emission path of the hot air, so that the hot air can be more effectively discharged upwards along the gap between the refrigerator and the cabinet, rather than accumulating on the side wall and the back side of the refrigerator.

[0125] In some possible embodiments, the base 610 can be provided with a plurality of fixing portions, and the base 610 can be fixedly connected with the back side of the cover plate 120 through the plurality of fixing portions. The base 610 is fixedly connected with the back side of the cover plate 120 through the fixing portions, thereby forming a stable structure, which can ensure that the connection between the base 610 and the back side of the cover plate 120 is more stable, and prevent the cover plate 120 from loosening or falling off due to vibration or other external forces. At the same time, the plurality of fixing portions arranged on the base 610 can facilitate the fixation of the base 610 on the back side of the cover plate 120, thereby simplifying the assembly process and reducing the difficulty and time cost of maintenance.

[0126] In some possible embodiments, the fixing portion can be designed as a protruding part with a screw hole, and the base 610 is fixed to the back side of the cover plate through cooperation of the screw and the screw hole. The fixing structure using the screw is simple and reliable, and can provide strong fixing force to ensure that the base 610 is stably connected to the cabinet. Meanwhile, the fixing using the screw is convenient for disassembly and reinstallation, and is conducive to the maintenance and repair of the refrigerator.

[0127] In some possible embodiments, the fixing portion can also be designed as a buckle structure, and the base 610 is buckled into the reserved clamping groove on the back side of the cover plate 120 through the buckle. The buckle fixing structure is fast to install and does not require additional tools, and can significantly improve the assembly efficiency. Meanwhile, the buckle structure is convenient for quick disassembly, and is convenient for maintenance and repair. The specific structure of the base 610 is not limited too much in the embodiments of the application as long as the fixing portion can fix the base 610 to the cover plate.

[0128] Referring to FIG. 24, in some possible embodiments, the base 610 can be provided with an extension groove 611. The extension groove 611 can extend along the length direction of the base 610. When the base 610 is installed, the extension groove 611 can extend in the horizontal direction.

[0129] The sealing portion 620 can be arranged in the extension groove 611, which means that the sealing portion 620 is embedded in the extension groove 611 and can slide or stretch in the extension groove 611. The sealing portion 620 can stretch in the direction close to or away from the cover plate 120. In this way, different installation requirements or the sealing effect of the refrigerator can be adapted, and the installation mode of the sealing portion and the base is simple and convenient, facilitating installation and replacement.

[0130] Referring to FIG. 24, in some possible embodiments, the extension groove 611 can be provided with an elastic member 612.

[0131] The first end of the elastic member 612 can be fixed to the base 610. The second end of the elastic member 612 can stretch in the direction close to or away from the cover plate 120. The second end of the elastic member 612 is connected to the sealing portion 620.

[0132] By arranging the elastic member 612, the sealing portion 620 can have certain adaptability to the distance of the gap between the refrigerator and the cabinet. When the installation gap of the refrigerator and the cabinet required is narrow, the elastic member 612 is compressed, so that the sealing portion 620 can abut against the cabinet; when the installation gap of the refrigerator and the cabinet required is wide, the elastic member 612 is elongated, so that the sealing portion 620 can abut against the cabinet, to ensure the sealing between the refrigerator and the cabinet; meanwhile, the elasticity of the elastic member 612 can provide a force to the sealing portion 620 towards the cabinet, so that the sealing between the refrigerator and the cabinet can be enhanced. The sealing mentioned above refers to the degree or effect of mutual isolation between the high-pressure wind area and the low-pressure wind area, so that the air in the low-pressure wind area cannot leak into the high-pressure wind area.

[0133] In some possible embodiments, the sealing part 620 can be provided as an elastic sealing part 620. The sealing part 620 can be in a strip shape.

[0134] By using the sealing part 620 with elasticity, the sealing part 620 is in flexible contact with the cabinet, which can adapt to slight protrusions on the surface of the cabinet, and strengthen the sealing between the refrigerator and the cabinet. The sealing part 620 with elasticity has good damping effect, which can reduce the vibration and noise generated during the operation of the refrigerator, improve the use comfort of the refrigerator, and prolong the service life of the refrigerator.

[0135] For example, the base 610 can be made of stainless steel. Stainless steel has high strength and rigidity, and can provide a stable support structure. Stainless steel has excellent corrosion resistance, and is suitable for use in a humid environment inside the refrigerator.

[0136] The base 610 can also be made of aluminum alloy. Aluminum alloy is light in weight, which helps to reduce the overall weight of the refrigerator. Aluminum alloy is easy to process into various shapes, which meets the design requirements of the shape of the elastic sealing part 620. As long as the base 610 can stably install the elastic sealing part 620 on the cabinet 1, the material of the base 610 is not limited in the embodiments of the present application.

[0137] For example, the sealing part 620 can be made of silica gel. Silica gel has excellent elasticity, which can ensure that the sealing part 620 is firmly installed on the base 610 and maintains good sealing performance when compressed and stretched. Silica gel has good aging resistance and can be used for a long time without deterioration.

[0138] The sealing part 620 can also be made of rubber. Rubber has excellent weather resistance and is suitable for long-term use. As long as the sealing part 620 can play a role in isolating the high-pressure wind area and the low-pressure wind area, the material of the sealing part 620 can also have various modifications, and is not limited to this.

[0139] The embodiments of the present application provide a refrigerator, which includes a cabinet 1, a compressor 200, a condenser 300, a fan 400, and a sealing part 600.

[0140] The rear side of the cabinet 1 is provided with a containing cavity 110. The containing cavity 110 contains the compressor 200 and the condenser 300 in communication.
