Description

Technical Field

[0002] Built-in refrigerators are embedded in the overall cabinets, which not only saves space, but also improves the aesthetics and practicality of the kitchen. Built-in refrigerators can be directly installed in the kitchen cabinets, making the appearance more neat and unified, and at the same time making better use of the limited space resources in the kitchen.

[0003] In order to achieve effective heat dissipation in embedded refrigerators and avoid performance degradation or even failure caused by overheating, a heat dissipation solution can be adopted by opening vents at the bottom of the refrigerator. The vents allow outside air to circulate into the heat dissipation area behind the refrigerator to help remove the heat generated by components such as the compressor and condenser. Specifically, the air inlet uses a small fan to suck air in and blow it toward the condenser, and the large fan sucks air from the condenser and blows it toward the compressor, and finally discharges it from the air outlet, which is a front-to-front heat dissipation solution.

[0004] However, in order to ensure ventilation, the front-to-front heat dissipation solution reserves a larger lower air outlet space, which affects the height of the cabinet. If a larger lower air outlet space is not reserved, the heat dissipation effect will be poor. Summary of the invention

DETAILED DESCRIPTION

[0042] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0043] For refrigerators embedded in cabinets, the heat dissipation system is set in the bottom compartment of the refrigerator. In some embodiments, the heat dissipation at the bottom of the refrigerator uses a fan to dissipate the hot air exchanged during the refrigeration process from the bottom by suction and blowing. This dynamic fan heat dissipation can improve the heat dissipation efficiency compared to traditional static heat pipe heat dissipation, and has less impact on the refrigerator itself.

[0044] When the refrigerator is in operation, the compressor and condenser generate heat. This heat is transferred to the heat dissipation system at the bottom of the refrigerator through the condenser. The fan in the bottom compartment starts to dissipate the heat from the bottom, forming natural convection or forced convection of air. The hot air is discharged into the surrounding environment through the air outlet at the bottom of the refrigerator, thereby achieving heat dissipation of the refrigerator.

[0045] To ensure the normal operation of the bottom cooling system, a larger air outlet space needs to be reserved at the bottom of the refrigerator. The reserved larger lower air outlet space affects the height of the cabinet. If no larger lower air outlet space is reserved, the cooling effect will be poor.

[0046] To solve the problem of poor heat dissipation, see Figure 1-Figure 4 Some embodiments of the present application provide a refrigerator bottom heat dissipation system, which is arranged in a bottom compartment 3 at the back of the refrigerator 2, wherein the bottom compartment 3 is close to the bottom of the refrigerator 2 and below the compartment.

[0047] The refrigerator bottom heat dissipation system includes: a bottom plate 11, which is a flat plate structure and serves as a substrate for other components. For example, a compressor 13, a water receiving tray 14, a fan assembly 15, a condenser 16, etc. are arranged on the bottom plate 11. The bottom plate 11 can be made of metal or other heat-conducting materials to facilitate heat conduction.

[0048] The water receiving tray 14 is used to collect condensed water or leaked refrigerant that may be generated by the condenser 16 or other parts of the refrigerator 2. The water receiving tray 14 runs through the bottom width direction. In some embodiments, the width of the water receiving tray 14 is the same as the width of the bottom plate 11, that is, it runs through the width direction of the bottom plate 11. The condenser 16 is arranged on one side of the water receiving tray 14 to collect condensed water or leaked refrigerant that may be generated by the condenser 16 or other parts of the refrigerator 2.

[0049] A fan assembly 15 is disposed on one side of the water receiving tray 14 close to the compressor 13 , and the compressor 13 and the fan assembly 15 are disposed on the same side.

[0050] A rear cover 12 is provided at the rear side of the bottom plate 11, wherein the rear cover 12 and the bottom plate 11 are arranged vertically, and a fan assembly 17 is provided on the side of the bottom plate 11 close to the rear cover 12, and the fan assembly 17 is fixed to the rear of the refrigerator 2 compartment through a fixing frame 22, and the fan assembly 17 includes a fan 172, a fan cover 173 and a fan seat 171, and the fan assembly 17 is used to generate airflow to help dissipate heat. The fan 172 generates wind by rotating blades, and the fan cover 173 and the fan seat 171 are used to fix the fan 172 and guide the airflow.

[0051] The fan 172 is mounted on the fan base 171. The fan 172 and the fan base 171 are installed in cooperation to form an internal air duct. The air duct away from the bottom plate 11 is provided with an air duct outlet 174, and the air duct outlet 174 is upward. The fan cover 173 is provided with an air duct inlet 1731, and the air duct inlet 1731 corresponds to the condenser 16. The front side of the bottom plate 11 is provided with an air inlet 21. When the fan 172 is working, the air volume enters from the air inlet 21, passes through the condenser 16, enters the air duct inlet 1731, passes through the fan 172, and blows to the air duct outlet 174, and blows the air out of the refrigerator 2, so as to achieve effective heat discharge.

[0052] The fan assembly 15 includes a fan 151 and a fixing bracket 152. The fan 151 is used to guide the airflow from the side of the compressor 13 to the condenser 16. The fixing bracket 152 is used to fix the position of the fan 151 and ensure that the fan 151 can work stably. The fan 151 is set on the water receiving tray 14 through the fixing bracket 152, and is set between the compressor 13 and the condenser 16. The heat generated by the compressor 13 can be guided to the condenser 16 through the airflow for heat dissipation. The fan 151 blows the air volume on one side of the compressor 13 to the condenser 16, and guides the air volume to the fan assembly 17, and blows it out of the refrigerator 2.

[0053] Exemplarily, the air volume enters from the air inlet 21 of the bottom plate 11, and the incoming air first passes through the condenser 16 to help the condenser 16 dissipate heat, and then enters the fan 172 through the air inlet 21 on the fan cover 173. The fan 172 sucks in the hot air after passing through the condenser 16, and blows it upward through the air duct outlet 174 on the fan cover 173, and discharges it out of the box through the back of the refrigerator 2. The fan 151 set on the water tray 14 blows the heat near the compressor 13 directly to the condenser 16, promoting the heat dissipation effect of the condenser 16, and this heat will also be discharged out of the box by the fan assembly 17. The fan assembly 15 and the fan assembly 17 each form an independent sub-wind field, and finally these airflows converge at the fan assembly 17 and are discharged out of the box together, which can achieve maximum air volume circulation and enhance the internal air circulation speed to make more efficient use of space while ensuring good heat dissipation effect.

[0054] In some embodiments, the fan cover 173 covers the fan 172 and forms a volute-like structure with the fan seat 171. The volute-like structure can convert high-speed radial airflow into axial airflow, thereby reducing turbulence and improving the stability and efficiency of the airflow. The fan seat 171 is used to fix the fan 172 and form a part of the airflow channel. The fan seat 171 is combined with the fan 172 to form a closed airflow channel so that the airflow can flow along a predetermined path. The fan cover 173 is provided with an air guide ring 1732, which is an annular structure provided on the fan cover 173, and is used to guide air into the air duct inlet 1731 to optimize the airflow direction.

[0055] Exemplarily, the air passing through the condenser 16 is guided to the air guide ring 1732 on the fan cover 173, and the air guide ring 1732 concentrates and guides the airflow into the air duct inlet 1731. The airflow flows smoothly inside the volute, and the airflow is discharged to the outside of the box through the air outlet 174 away from the air duct.

[0056] Since the heat dissipation system is to dissipate the heat generated inside the refrigerator 2 and the heat generated when the compressor 13 is working, the condenser 16 and the compressor 13 are arranged on the bottom plate 11. In order to effectively dissipate the heat, the condenser 16 transfers the internal heat to the outside to ensure that the refrigerator 2 can operate normally and maintain a low temperature state. To further improve the efficiency of heat dissipation, in some embodiments, the refrigerator bottom heat dissipation system further includes: a temperature sensor and a controller, and the temperature sensor is configured to detect the temperature of the compressor 13.

[0057] The controller is configured to:

[0058] Get the temperature result detected by the temperature sensor;

[0059] If the temperature result is greater than or equal to the temperature threshold, send a command to the fan 172 to increase the speed of the fan 172;

[0060] If the temperature result is less than the temperature threshold, a command is sent to the fan 172 to reduce the rotation speed of the fan 172 .

[0061] If the temperature result is greater than or equal to the temperature threshold, it indicates that the compressor 13 is currently in a high temperature state and requires additional cooling. At this time, the controller will send an instruction to the fan 172 to control it to increase the speed to speed up the heat dissipation and reduce the temperature of the compressor 13. If the temperature result is less than the temperature threshold, it indicates that the current temperature of the compressor 13 is moderate and does not require additional cooling. In order to save energy and reduce noise, the controller will send an instruction to the fan 172 to control it to reduce the speed.

[0062] In order to increase the heat dissipation efficiency, an air baffle 111 is provided on the fixed bracket 152 near the water tray 14. The air baffle 111 is used to separate the air inlet 21 into a first air inlet and a second air inlet, wherein the first air inlet corresponds to the compressor 13 to take in air from the compressor 13 side, and the second air inlet corresponds to the condenser 16 to take in air from the condenser 16 side, so as to ensure that the compressor 13 and the condenser 16 respectively obtain independent cooling air flows.

[0063] It is understandable that the first air inlet may be toward the compressor 13, and the second air inlet may be toward the condenser 16. In some embodiments, the first air inlet and the second air inlet may be decomposed into air inlets in multiple directions to guide air into the cooling system at the bottom of the refrigerator 2 from multiple angles, which can ensure that the airflow inside the cooling system at the bottom of the refrigerator 2 is more uniform and improve the cooling effect.

[0064] The first air inlet corresponds to the compressor 13, that is, the air entering from the front side will first be guided to the vicinity of the compressor 13 to help cool the compressor 13. The second air inlet corresponds to the condenser 16, that is, the air entering from the front side will also be guided to the condenser 16 to help the condenser 16 dissipate heat. The air flow can be made more reasonable, and different components can obtain cooling air as needed, thereby improving the heat dissipation efficiency of the system, and reducing the turbulence of the air in the system and reducing energy consumption.

[0065] Since the compressor 13 generates a lot of heat, in some embodiments, an adjustment plate is provided on the air baffle 111, and the adjustment plate can be used to adjust the position of the air baffle 111. The adjustment plate may include a motor and a regulator, and the motor provides power to drive the regulator to change the position of the air baffle 111. The regulator connects the motor and the air baffle 111, and adjusts the position of the air baffle 111 according to the drive of the motor.

[0066] The controller is configured to:

[0067] Get the temperature result detected by the temperature sensor;

[0068] If the temperature result is greater than or equal to the temperature threshold, a command is sent to the motor to control the motor to drive the regulator to adjust the position of the wind shield 111.

[0069] That is to say, when the temperature reaches or exceeds the set threshold, the controller will start the motor, and then adjust the position of the wind baffle 111 through the regulator to increase the area of ​​the first air inlet. A larger air inlet allows more air to flow into the compressor 13 area, thereby increasing the air flow rate and taking away more heat, thereby improving the heat dissipation efficiency of the system.

[0070] In some embodiments, the water receiving tray 14 is provided with a first island 141 and a second island 142, the first island 141 is used to fix the fan assembly 15, and the second island 142 is used to fix the condenser 16; the first island 141 and the second island 142 are protruding structures provided on the water receiving tray 14, and are used to fix the fan assembly 15 and the condenser 16. In this embodiment, there is no limitation on the structures of the first island 141 and the second island 142.

[0071] Since the water receiving tray 14 is used to receive condensed water, the heights of the first island platform 141 and the second island platform 142 are higher than the height of the water receiving tray 14 when it is full of water. That is to say, even if the water receiving tray 14 is full of condensed water, the fan assembly 15 and the condenser 16 will not be soaked in water, ensuring normal operation.

[0072] In some embodiments, a splash shield may be provided around the first island 141 and the second island 142 to prevent condensed water from splashing onto the fan assembly 15 and the condenser 16 .

[0073] In some embodiments, a plurality of ventilation holes are provided on the back cover 12 and soft sealing strips are attached around the back cover 12 to form a closed wind field to ensure that the airflow flows along the expected path.

[0074] Exemplarily, air enters from the air inlet 21 on the front side of the base plate 11, undergoes heat exchange through the condenser 16, and the air passing through the condenser 16 is guided to the air guide ring 1732 on the fan cover 173. The air guide ring 1732 concentrates the airflow and guides it into the air duct inlet 1731. The fan cover 173 covers the fan 172 and forms a volute-like structure with the fan base 171. The airflow flows smoothly inside the volute, passes through the air duct outlet 174 on the rear cover 12, and is discharged to the outside of the box through the ventilation holes.

[0075] In some embodiments, the back of the refrigerator 2 includes a back plate 23 , and a pit 230 is provided on the back plate 23 . The pit 230 corresponds to the air duct outlet 174 , and the air volume is blown out of the refrigerator 2 through the pit 230 .

[0076] The air enters from the air inlet 21 on the bottom plate 11, undergoes heat exchange through the condenser 16, and the air passing through the condenser 16 is guided to the air guide ring 1732 on the fan cover 173. The air guide ring 1732 concentrates and guides the airflow into the air duct inlet 1731, and is discharged into the bottom chamber 3 through the ventilation holes. The exhausted hot air is discharged to the outside of the refrigerator 2 through the pit 230 on the back plate 23.

[0077] It is understandable that a plurality of pits 230 may be provided on the back plate 23 to better disperse the heat released by the condenser 16 and improve the heat dissipation efficiency. In addition, to improve the heat exchange efficiency, the material of the back plate 23 may be set to a material with high thermal conductivity, such as aluminum, copper, carbon fiber composite material, etc.

[0078] Based on the above-mentioned heat dissipation system at the bottom of a refrigerator, some embodiments of the present application also provide a refrigerator, including a heat dissipation system at the bottom of a refrigerator. The refrigerator provided in the embodiment of the present application is a refrigeration device, which at least includes a refrigeration system, a cooling system, a control system and a cabinet to achieve refrigeration and operation. Among them, the refrigeration system is used to produce a refrigeration effect, the cooling system is used to maintain a low temperature environment, the control system is used to control the temperature and humidity in the refrigerator, etc., and the cabinet is used to provide storage space. It can be understood that the refrigeration system, the cooling system, and the control system include specific components that can achieve the above functions.

[0079] In some embodiments, the refrigeration system includes a compressor, a condenser, an evaporator, and a throttling device. Among them, the compressor is used to compress the refrigerant gas, increase the pressure and temperature, and thus promote the flow of the refrigerant in the system. During the compression process, the refrigerant changes from a low-pressure and high-temperature gas to a high-pressure and high-temperature gas, thereby producing a refrigeration effect. The condenser is used to cool the high-temperature and high-pressure gas discharged from the compressor into a liquid state. The heat is released through the heat sink, and the refrigerant gas is converted into a liquid state, ready to enter the next step of the refrigeration cycle. The evaporator is used to absorb heat in the refrigeration system. The refrigerant evaporates from a liquid state to a gas state in the evaporator, absorbing heat from the surrounding environment, thereby achieving the purpose of lowering the temperature inside the refrigerator. The throttling device may include an expansion valve and a capillary tube, which are used to adjust the flow rate of the refrigerant, reduce its pressure, and make it become a low-temperature and low-pressure gas-liquid mixed state, ready to enter the evaporator.

[0080] In some embodiments, the cooling system includes a fan connected to the evaporator. The fan circulates air in the compartments, such as the freezer and refrigerator, to transfer heat to the evaporator, helping to maintain a low temperature environment inside the refrigerator.

[0081] It should be noted that the above example is merely a simple division of the functions of the refrigerator and does not constitute a limitation on the specific structure of the refrigerator in the embodiment of the present application.
