[0063] As described in the background art, in the related art, an embedded refrigerator includes a condenser and a receiving cavity for placing a refrigeration system. Among them, the condenser is disposed in the receiving cavity. When the embedded refrigerator is in operation, the condenser generates heat, causing the temperature of the embedded refrigerator to rise. A blower is provided in the receiving cavity. The blower uses forced convection to suck in the air that has undergone heat exchange through the condenser and discharge it outside the receiving cavity. In this way, heat dissipation of the condenser can be achieved.

[0064] However, since the side wall and the rear side of the embedded refrigerator usually need to be close to the inner wall of the cabinet. Moreover, there is a certain distance between the condenser and the blower, and only a part of the air that has undergone heat exchange through the condenser is sucked out by the blower, resulting in poor heat dissipation effect of the embedded refrigerator, and the embedded refrigerator is prone to local overheating and other situations.

[0065] In view of this, in the refrigerator according to the embodiment of the present application, a receiving cavity is provided at the rear side of the cabinet body. Both the compressor and the condenser are disposed in the receiving cavity, and the condenser is communicated with the compressor. By connecting the blower to the condenser, the air inlet of the blower faces the condenser, and the blower is provided with an exhaust duct connected to the cabinet body. The first end of the exhaust duct is communicated with the air outlet of the blower, and the second end of the exhaust duct is located outside the receiving cavity. When the blower operates, the heat generated by the condenser exchanges heat with the surrounding air, and the hot air is sucked away by the blower. The blower can accelerate the flow of the hot air, reduce the residence time of the hot air on the condenser, and improve the heat dissipation efficiency. Connecting the blower to the condenser can reduce the path for the hot air to transfer from the condenser to the blower, enabling the hot air to be discharged outside the receiving cavity through the blower, preventing heat from accumulating in the receiving cavity, ensuring that the temperature in the receiving cavity will not be too high, and avoiding the risk of damaging the internal electronic components of the refrigerator due to local overheating.

[0066] To make the purpose, implementation mode and advantages of the present application clearer, the following will clearly and completely describe the exemplary implementation mode of the present application with reference to the accompanying drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0068] In addition, the terms "include" and "have" and any of their variations are intended to cover but not exclude inclusion.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0070] The terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include one or more of such features.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0072] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0073] The embodiments of the present application provide a refrigerator, which is an indispensable electrical appliance in modern families and can extend the freshness period of food.

[0074] Specifically, the refrigerator can be set as an embedded refrigerator and embedded in a cabinet or a wall. The embedded refrigerator can be integrated with the cabinet or the wall, improving the overall aesthetics of the kitchen.

[0075] Refer to Figure 1 As shown, the refrigerator includes a box body 10. The box body 10 protects key components such as the refrigeration system and the control system inside it, and the box body 10 ensures that these components are not affected by external impacts or damages during operation. The box body 10 can also provide a storage space for food to ensure the freshness of food.

[0076] Exemplarily, the heat dissipation system of the refrigerator usually discharges the hot air after heat exchange from the rear side of the cabinet body 10 to the outside of the refrigerator. The refrigerator is embedded in a cabinet body or a wall body, and a specific ventilation channel is formed between the rear side of the cabinet body 10 and the surrounding embedded cabinet body or wall body. An exhaust port is provided at the top position of the cabinet body or the wall body. In this way, an upward channel is formed, and natural convection is utilized to accelerate and promote the flow of hot air, thereby improving the heat dissipation efficiency of the refrigerator.

[0077] The refrigerator includes a door body, and the door body is used to enclose the internal space of the cabinet body 10 to prevent cold air from leaking.

[0078] For the convenience of description and understanding, the side of the refrigerator where the door body is provided is defined as the front side of the cabinet body 10, and the rear side of the cabinet body 10 is arranged opposite to the front side of the cabinet body 10.

[0079] A receiving cavity 110 is provided on the rear side of the cabinet body 10, and the cabinet body 10 provides support for the receiving cavity 110.

[0080] The receiving cavity 110 of the cabinet body can be used to accommodate and install various key components or accessories of the refrigerator. For example, the receiving cavity 110 can accommodate components such as a compressor, a condenser, and a fan.

[0081] The receiving cavity 110 is arranged on the rear side of the cabinet body, so that these components do not occupy the internal storage space of the refrigerator, and at the same time, it is also convenient for the components to be maintained and replaced.

[0082] A detachable cover plate 120 is provided on the rear side of the cabinet body 10, and the cover plate 120 is used to close the receiving cavity 110. The closing function of the cover plate can protect the components or accessories in the receiving cavity 110 from the influence of the external environment. For example, the cover plate can prevent dust, moisture, etc. from entering the receiving cavity 110, resulting in a decrease in the heat dissipation performance or insulation performance of the components or accessories in the receiving cavity 110.

[0083] The cover plate 120 is arranged to be detachably connected to the receiving cavity 110, which can facilitate the opening and closing of the receiving cavity 110, thereby facilitating the inspection, maintenance, and replacement of the components or accessories in the receiving cavity 110.

[0084] In some embodiments of the present application, the cover plate 120 is used to close a part of the receiving cavity 110. The unclosed area of the receiving cavity 110 can be used for the heat dissipation of the components or accessories in the receiving cavity 110, thereby improving the heat dissipation efficiency of the components or accessories in the receiving cavity 110.

[0085] The cabinet body 10 is provided with an installation structure 130, and the installation structure 130 can be used to install and support various components in the receiving cavity 110 to ensure that these components remain stable and reliable during the operation of the refrigerator.

[0086] Exemplarily, the mounting structure 130 may include various brackets, fasteners, snaps, etc., for supporting and mounting different components. By designing the mounting structure 130, it can be ensured that the components will not be displaced or loosened during the operation of the refrigerator, thereby improving the reliability and service life of the refrigerator.

[0087] The refrigerator may include a compressor 20, which is one of the core components of the refrigerator and is responsible for compressing the refrigerant from a low-pressure gaseous state into a high-pressure gaseous state. During this process, the temperature and pressure of the refrigerant will both increase.

[0088] The compressor 20 is disposed in the accommodation cavity 110, and the accommodation cavity 110 can isolate the noise and vibration generated by the compressor 20, improving the overall performance and user experience of the refrigerator.

[0089] The refrigerator may include a condenser 30, which can cool and condense the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 20 into a liquid state. This process is usually achieved through heat exchange. After being condensed by the condenser 30, the temperature of the refrigerant decreases, but the pressure remains high.

[0090] The condenser 30 is disposed in the accommodation cavity 110, and the accommodation cavity 110 can protect the condenser 30 from the influence of the external environment and extend the service life of the condenser 30.

[0091] The condenser 30 is connected to the compressor 20, which can ensure the smooth circulation of the refrigerant in the system, ensuring the smooth flow of the refrigerant during the processes of compression, condensation, expansion, and evaporation, and ensuring the refrigeration efficiency and effect.

[0092] The refrigerator may include a throttle valve (not shown in the figure), which can quickly reduce the pressure of the high-pressure liquid refrigerant. The throttle valve adjusts the refrigeration capacity of the refrigeration system by controlling the flow rate of the refrigerant.

[0093] The refrigerator may include an evaporator (not shown in the figure), which absorbs heat to convert the refrigerant from a liquid state to a gaseous state, thereby reducing the temperature inside the refrigerator.

[0094] Exemplarily, the refrigeration principle of the refrigerator is as follows: The compressor 20 compresses the low-pressure and low-temperature refrigerant gas to form a high-temperature and high-pressure gas. The compressor 20 sends the compressed refrigerant into the condenser 30 connected to the compressor 20. Then, the condenser 30 condenses the compressed refrigerant into a liquid state and releases the heat to the surrounding environment. Next, the throttle valve expands the high-pressure liquid refrigerant in the condenser 30 into a low-pressure liquid refrigerant. Finally, the low-pressure liquid refrigerant absorbs heat in the evaporator, completely evaporates into a gaseous state, reduces the temperature inside the refrigerator, and returns the refrigerant gas in the low-temperature and low-pressure state to the compressor 20. The evaporator can achieve the refrigeration effect by using the heat exchange of the refrigerant.

[0095] Reference Figure 1 and Figure 2 As shown, the refrigerator may include a blower 40, which can enhance the heat dissipation effect of the condenser 30 and improve the efficiency of the refrigeration system. Through the forced air flow generated by the blower 40, the heat dissipation from the surface of the condenser 30 can be accelerated, so that the refrigerant condenses into a liquid state.

[0096] The blower 40 can be set as one or more of a centrifugal blower, a cross-flow blower, and an axial-flow blower, which can meet various use requirements. Further, the blower 40 can be set as a centrifugal blower. A centrifugal blower can suck air from the axis through a rotating impeller, and then use centrifugal force to throw the air radially outward, thereby increasing the air flow rate and pressure.

[0097] Specifically, the centrifugal blower is provided with a volute and an impeller. Through the guidance of the volute, after the gas is thrown out from the impeller, it flows along the inner wall of the volute, and the air flow direction changes from axial to radial, and the air flow direction can achieve a change of about 90 degrees.

[0098] Reference Figure 3 and Figure 4 As shown, the blower 40 includes an air inlet 410 and an air outlet 420. When the blower operates, air enters from the air inlet 410, passes through the impeller of the blower 40, and the impeller rotates at a high speed, generating a strong centrifugal force to drive the air flow, which is accelerated and changes the flow direction, and is discharged from the air outlet 420.

[0099] Reference Figure 1 and Figure 5 As shown, the blower 40 is connected to the condenser 30. When the blower operates, the heat generated by the condenser 30 exchanges heat with the surrounding air, is sucked away by the blower 40 and accelerates the air flow, reducing the residence time of the heat on the condenser 30 and enhancing the heat dissipation effect of the condenser 30.

[0100] Connecting the blower 40 to the condenser 30 can reduce the path for hot air to transfer from the condenser 30 to the blower 40, enabling the hot air to be discharged through the blower 40, preventing the accumulation of hot air in the accommodation cavity 110, ensuring that the temperature in the accommodation cavity 110 is not too high, and avoiding the risk of damaging the internal electronic components of the refrigerator due to local overheating.

[0101] Connecting the blower 40 to the condenser 30 can also save space in the accommodation cavity 110, improve the utilization rate of the space in the accommodation cavity 110, and is beneficial to expanding the storage space of the refrigerator.

[0102] The air inlet 410 of the blower 40 faces the condenser 30, and the air inlet 410 is directly aligned with the condenser 30 to ensure that the blower 40 increases the air flow speed, enabling the air to directly carry away the heat on the surface of the condenser 30 or absorb the heat released by the condenser 30.

[0103] The blower 40 and the condenser 30 are arranged along the connection direction of the front side and the rear side of the box body 10, and the blower 40 is closer to the rear side of the box body 10 relative to the condenser 30. The blower 40 is located at the rear side of the box body 10, which is convenient for the installation of the blower 40, thereby reducing the vibration of the blower 40 and reducing the noise of the blower 40. Such an arrangement can reserve sufficient air intake space for the blower 40 to ensure that the blower 40 can inhale air and dissipate heat.

[0104] Refer to Figure 4 and Figure 5 As shown, the blower 40 is provided with an exhaust air duct 50. The exhaust air duct 50 ensures that the air is guided to the outside of the refrigerator, avoiding the circulation of air in the refrigerator accommodation cavity 110 and reducing the risk of temperature rise in the accommodation cavity 110. The exhaust air duct 50 can also reduce the air reflux caused by the change of external wind pressure and ensure the heat dissipation effect of the refrigerator.

[0105] The exhaust air duct 50 is connected to the box body 10. The exhaust air duct 50 includes a first end 510 of the exhaust air duct and a second end 520 of the exhaust air duct. It is easy to understand that the first end 510 and the second end 520 of the exhaust air duct are the air inlets at both ends of the exhaust air duct 50.

[0106] The first end 510 of the exhaust air duct is communicated with the air outlet 420 of the blower 40, and the second end 520 of the exhaust air duct is located outside the accommodation cavity 110. Such an arrangement ensures that the air sucked away by the condenser 30 can pass through the blower 40 smoothly and then be directly discharged outside the refrigerator through the exhaust air duct 50, so that the hot air in the accommodation cavity 110 can be dissipated.

[0107] Specifically, when the cover plate 120 closes the accommodation cavity 110, the exhaust air duct 50 is arranged on the mounting structure 130. This ensures the stable installation of the exhaust air duct 50, reduces the probability of noise and damage caused by vibration or movement, and improves the reliability of the connection between the blower 40 and the exhaust air duct 50.

[0108] The second end 520 of the exhaust air duct is located outside the cover plate 120. The exhaust air duct 50 is connected to the box body 10 through the mounting structure 130, which is convenient for the installation and maintenance of the exhaust air duct 50, optimizes the space layout in the accommodation cavity 110, and is beneficial to improving the compactness in the accommodation cavity 110.

[0109] The blower 40 absorbs the air flow from the condenser 30 through the air inlet 410, and the blower 40 discharges the air flow from the condenser 30 to the outside of the accommodation cavity 110 at least through the exhaust air duct 50. The blower 40 discharges this air to the outside of the accommodation cavity 110, which can reduce the temperature of both the condenser 30 and the accommodation cavity 110 and improve the heat dissipation effect.

[0110] In some embodiments of the present application, in addition to sucking the air passing through the condenser 30, the fan 40 can also suck the air in other areas of the accommodation cavity 110 to improve the heat dissipation efficiency in the accommodation cavity 110.

[0111] Continuing to refer to Figure 4 and Figure 5 As shown, the exhaust duct 50 is provided with a wind guide plate 530. The wind guide plate 530 can enable the air to flow in the exhaust duct 50 along a predetermined path, reduce the vortex and turbulent flow phenomena during the air flow, and improve the heat dissipation efficiency of the condenser 30.

[0112] Further, the wind guide plate 530 includes a first end 531 of the wind guide plate and a second end 532 of the wind guide plate. The first end 531 of the wind guide plate and the second end 532 of the wind guide plate are located on both sides of the wind guide plate 530.

[0113] The first end 531 of the wind guide plate is connected to the second end 520 of the exhaust duct, and the second end 532 of the wind guide plate extends upward. With such a setting, the hot air discharged from the exhaust duct 50 can be guided to flow upward, avoiding the accumulation of hot air around the fan 40 or the exhaust duct 50, thereby improving the air flow efficiency. This can ensure that the hot air is guided out of the refrigerator, improving the heat dissipation effect of the condenser 30.

[0114] The wind guide plate 530 is inclined. The inclined wind guide plate 530 can guide the air to flow in a predetermined direction, enabling the air to flow smoothly along the inclined direction of the wind guide plate 530, reducing the resistance and vortex phenomena during the air flow, and thus improving the heat dissipation efficiency of the condenser 30.

[0115] The second end 532 of the wind guide plate is farther from the front side of the cabinet 10 relative to the first end 531 of the wind guide plate, and the second end 532 of the wind guide plate is connected to the rear shell of the cabinet 10. That is to say, along the height direction of the refrigerator, the wind guide plate 530 is inclined backward. On the basis of ensuring the heat dissipation effect, with such a setting, the neatness and beauty of the front side and the left and right sides of the refrigerator can be maintained.

[0116] The air outlet 420 of the fan 40 is arranged upward. In this way, the principle of natural convection and the characteristic that hot air naturally rises can be utilized. With such a setting, the hot air can be discharged from the air outlet 420 of the fan 40, preventing the accumulation of hot air inside the accommodation cavity 110, and improving the air flow efficiency and the overall heat dissipation effect.

[0117] The hot air discharged from the air outlet of the blower 40 will rise naturally. Therefore, the second end 520 of the exhaust duct is arranged above the first end 510 of the exhaust duct. That is to say, the height of the second end 520 of the exhaust duct is higher, and the exhaust duct 50 is arranged to extend upward. When the blower 40 is running, the hot air discharged by the blower 40 can flow upward along the exhaust duct 50, reducing the flow resistance and improving the efficiency of hot air discharge.

[0118] The refrigerator provided by the embodiment of the present application further includes a mounting bracket 60, and the mounting bracket 60 can provide structural support to prevent the components from shifting or loosening during operation.

[0119] Referring to Figure 6 、 Figure 7 and Figure 8 As shown, further, the mounting bracket 60 can be set to be hollow. In this way, the mounting bracket 60 can ensure its own strength and have a lighter weight.

[0120] The hollow inner side of the mounting bracket 60 can be used to accommodate the condenser 30, and the condenser 30 is connected to the blower 40 through the mounting bracket 60. During the operation of the refrigerator, this can improve the stability of the condenser 30.

[0121] In some embodiments of the present application, the mounting bracket 60 can be set as a rectangular bracket, which is designed to conform to the shape of the condenser 30 to accommodate the condenser 30 and reduce the volume of the mounting bracket 60.

[0122] The first end 610 of the mounting bracket is connected to the condenser 30. During the operation of the blower 40, vibrations will be generated, and the condenser 30 connected to the blower 40 will also vibrate. The first end 610 of the mounting bracket is connected to the condenser 30, providing support for the condenser 30 to prevent the condenser 30 from shifting or being damaged during operation.

[0123] The second end 620 of the mounting bracket is connected to the blower 40. Similarly, during the operation of the blower 40, vibrations will be generated, which can ensure that the blower 40 remains stable during operation and prevent the blower 40 from shifting or loosening due to vibrations or other factors. This can improve the working efficiency and service life of the blower 40 and ensure the normal operation of the refrigeration system of the refrigerator.

[0124] The blower 40 and the condenser 30 are connected as a whole through the mounting bracket 60, so that the heat generated by the condenser 30 can be absorbed by the blower 40 and the air flow can be accelerated, reducing the residence time of heat on the condenser 30 and enhancing the heat dissipation efficiency.

[0125] The mounting bracket 60 is arranged on the cabinet 10 to improve the stability of the mounting bracket 60, and further ensure the normal operation of the condenser 30 and the blower 40.

[0126] ]Specifically, the outer side of the mounting bracket 60 is connected to the box body 10, making the installation process of the mounting bracket 60 simple and fast. At the same time, when the condenser 30 needs to be maintained and replaced, the mounting bracket 60 can be disassembled and assembled, reducing the maintenance cost and time cost of the condenser 30.

[0127] The mounting bracket 60 is provided with a diversion channel 630. By optimizing the air flow path, the heat generated by the condenser is heat-exchanged with the surrounding air, and the diversion channel 630 can take away the hot air after heat exchange and guide it to the fan 40 for discharge.

[0128] Furthermore, the diversion channel 630 is formed through the inner side of the mounting bracket 60. A large amount of hot air is generated during the operation of the condenser 30. The diversion channel 630 can optimize the air flow path between the condenser 30 and the fan 40, ensuring that the hot air dissipated by the condenser 30 can be guided to the fan 40. This can improve the efficiency of the air flow and the heat dissipation effect, prevent the hot air from staying in the accommodation cavity 110, and improve the overall heat dissipation performance.

[0129] The diversion channel 630 includes a first end 631 of the diversion channel and a second end 632 of the diversion channel. The first end 631 of the diversion channel and the second end 632 of the diversion channel are located at both ends of the diversion channel 630.

[0130] The first end 631 of the diversion channel faces the condenser 30. When heat exchange occurs in the condenser 30 to form hot air, the hot air can flow through the diversion channel 630, preventing the hot air from diffusing into the accommodation cavity 110 and causing the temperature in the accommodation cavity 110 to rise. The second end 632 of the diversion channel is communicated with the air inlet 410 of the fan 40, ensuring the continuity and stability of the air flow. With such a setting, the hot air in the diversion channel 630 can enter the fan 40, ensuring the flow effect of the air flow and improving the heat dissipation efficiency of the refrigerator.

[0131] Refer to Figure 9 、 Figure 10 and Figure 11 as shown, the heat dissipation process of the condenser is described in detail with examples below:

[0132] First, after the fan 40 is started, the rotating impeller generates a negative pressure effect. Under the traction of the negative pressure, the air at the bottom of the refrigerator box body 10 is sucked into the accommodation cavity 110 to form flowing air.

[0133] Then, the flowing air enters the condenser 30 from the first end 610 of the mounting bracket. Inside the condenser 30, the air exchanges heat with the surface of the condenser. During this process, the heat of the condenser 30 is transferred to the air, causing the temperature of the condenser 30 to drop, while the temperature of the air around the condenser 30 rises accordingly.

[0134] Then, the air heated through heat exchange flows towards the first end 631 of the diversion channel of the condenser 30. The hot air then flows along the diversion channel 630 to the second end 632 of the diversion channel. The second end 632 of the diversion channel is in communication with the air inlet 410 of the fan 40, and the hot air enters the fan 40.

[0135] Finally, as the impeller of the fan 40 continuously rotates, the hot air is accelerated and thrown out radially by the centrifugal force generated by the rotation. The accelerated hot air flows out from the air outlet 420 of the fan 40 and then enters the first end 510 of the exhaust duct communicated therewith. Under the guidance of the air deflector 530, the hot air flows towards the second end 520 of the exhaust duct. It is discharged from the second end 520 of the exhaust duct out of the accommodation cavity 110 of the refrigerator.

[0136] Through the above steps, the effective circulation of the air inside the accommodation cavity 110 of the refrigerator and the timely discharge of heat are ensured, thereby maintaining the low-temperature environment inside the refrigerator and avoiding the risk of damaging the internal electronic components of the refrigerator due to local overheating.

[0137] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
