[0003] To realize effective heat dissipation of the embedded refrigerator and avoid performance decline or even failure caused by overheating, a heat dissipation scheme of opening a ventilation opening at the lower part of the refrigerator can be adopted.

DETAILED DESCRIPTION

[0042] The embodiments will be described in detail below with reference to the drawings. Unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The embodiments described in the following examples do not represent all the implementations consistent with the present application. They are merely examples of systems and methods consistent with some aspects of the present application as recited in the detailed description of the claims.

[0043] For a refrigerator embedded in a cabinet, the heat dissipation system is arranged in the bottom chamber of the refrigerator. In some embodiments, the refrigerator bottom heat dissipation utilizes 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 efficiency of heat dissipation compared with the traditional static heat dissipation pipe, and has less impact on the refrigerator itself.

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

[0045] To ensure the normal operation of the bottom heat dissipation system, a larger air outlet space needs to be reserved at the bottom of the refrigerator. The larger lower air outlet space reserved affects the height of the cabinet. If a larger lower air outlet space is not reserved, the heat dissipation effect is poor.

[0046] To solve the problem of poor heat dissipation effect, see Figures 1-4 The refrigerator bottom heat dissipation system is provided in the bottom compartment 3 of the refrigerator 2 rear back, wherein the bottom compartment 3 is close to the bottom of the refrigerator 2, below the compartment.

[0047] The refrigerator bottom heat dissipation system includes a bottom plate 11, which is a flat structure and serves as a base plate for other components, such as a compressor 13, a water pan 14, a fan assembly 15, a condenser 16, etc. The bottom plate 11 can be made of metal or other heat-conducting materials to facilitate heat conduction.

[0048] The water pan 14 is used to collect condensate water or leaked refrigerant that may be generated by the condenser 16 or other parts of the refrigerator 2, and the water pan 14 extends through the width direction of the bottom. In some embodiments, the width of the water pan 14 is the same as the width of the bottom plate 11, i.e. it extends through the width direction of the bottom plate 11, and the condenser 16 is arranged on one side of the water pan 14 for collecting condensate water or leaked refrigerant that may be generated by the condenser 16 or other parts of the refrigerator 2.

[0049] The water pan 14 is provided with a fan assembly 15 on the side close to the compressor 13, and the compressor 13 and the fan assembly 15 are arranged on the same side.

[0050] The rear side of the bottom plate 11 is provided with a rear cover 12, wherein the rear cover 12 is vertically arranged with the bottom plate 11, and the bottom plate 11 is provided with a fan assembly 17 on the side close to the rear cover 12. The fan assembly 17 is fixed to the rear compartment of the refrigerator 2 by a fixing frame 22, and the fan assembly 17 includes a fan 172, a fan cover 173 and a fan seat 171. The fan assembly 17 is used to generate airflow to help heat dissipation. The fan 172 generates wind through 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 installed on the fan seat 171, and the fan 172 is installed in cooperation with the fan seat 171 to form an internal air duct. An air duct air outlet 174 is arranged on the air duct away from the bottom plate 11, and the air duct air outlet 174 faces upward. An air duct air inlet 1731 is arranged on the fan cover 173, and the air duct air 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 air inlet 1731, passes through the fan 172, and blows toward the air duct air outlet 174 to blow the air out of the refrigerator 2, so as to realize effective heat dissipation.

[0052] The fan assembly 15 includes a fan 151 and a fixed support 152. The fan 151 is used to guide the airflow from the side of the compressor 13 to the condenser 16. The fixed support 152 is used to fix the position of the fan 151 and ensure that the fan 151 can work stably. The fan 151 is arranged on the water pan 14 through the fixed support 152 and is arranged between the compressor 13 and the condenser 16. The fan 151 can guide the heat generated by the compressor 13 to the condenser 16 through the airflow to dissipate heat. The fan 151 blows the air volume on the side of the compressor 13 to the condenser 16, and guides the air volume to the fan assembly 17 to blow out of the refrigerator 2.

[0053] For example, the air volume enters from the air inlet 21 of the bottom plate 11. The entering 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 the hot air after passing through the condenser 16 and blows it upward through the air duct air outlet 174 on the fan cover 173 and then out of the refrigerator 2 through the back of the refrigerator 2. The fan 151 arranged on the water pan 14 directly blows the heat near the compressor 13 to the condenser 16 to promote the heat dissipation effect of the condenser 16. These heat is also discharged out of the refrigerator 2 by the fan assembly 17. The fan assembly 15 and the fan assembly 17 each form an independent sub-air field. Finally, these airflows converge at the fan assembly 17 and are discharged out of the refrigerator 2 together, which can realize maximum air volume circulation and strengthen the internal air circulation speed to more effectively utilize the space while ensuring good heat dissipation effect.

[0054] In some embodiments, the fan cover 173 covers the fan 172 and forms a volute structure with the fan seat 171. The volute 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 part of the airflow passage. The fan seat 171 and the fan 172 combine to form a closed airflow passage, so that the airflow can flow along a predetermined path. The fan cover 173 is provided with a wind guide ring 1732. The wind guide ring 1732 is an annular structure arranged on the fan cover 173 and is used to guide air into the air duct air inlet 1731 to optimize the airflow direction.

[0055] For example, 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 air flow into the air duct air inlet 1731, and the air flow flows smoothly inside the volute, and the air flow is discharged to the outside of the cabinet through the air duct air outlet 174 away from the air duct air outlet 174.

[0056] Since the heat dissipation system dissipates the heat generated inside the refrigerator 2 and the heat generated when the compressor 13 is working, and the condenser 16 and the compressor 13 are arranged on the bottom plate 11, in order to effectively dissipate heat, the condenser 16 transfers the heat inside to the outside to ensure that the refrigerator 2 can operate normally and maintain a low temperature. In order to further improve the efficiency of heat dissipation, in some embodiments, the bottom heat dissipation system of the refrigerator further comprises 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] obtain the temperature result detected by the temperature sensor;

[0059] if the temperature result is greater than or equal to the temperature threshold, send an instruction to the fan 172 to increase the rotating speed of the fan 172;

[0060] if the temperature result is less than the temperature threshold, send an instruction to the fan 172 to reduce the rotating 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 needs additional cooling. At this time, the controller will send an instruction to the fan 172 to control it to increase the rotating speed to speed up the heat dissipation speed 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 need 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 rotating speed.

[0062] In order to increase the heat dissipation efficiency, the fixed support 152 close to the water tray 14 is provided with an air baffle 111, and the air baffle 111 is used to divide 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 air from the side of the compressor 13, and the second air inlet corresponds to the condenser 16 to air from the side of the condenser 16, so as to ensure that the compressor 13 and the condenser 16 respectively obtain independent cooling air flow.

[0063] It can be understood that the first air inlet can be towards the compressor 13 side, and the second air inlet can be towards the condenser 16. In some embodiments, the first air inlet and the second air inlet can be decomposed into multiple directional air inlets to guide air to enter the refrigerator 2 bottom heat dissipation system from multiple angles, which can ensure that the air flow inside the refrigerator 2 bottom heat dissipation system is more uniform, and improve the heat dissipation effect.

[0064] The first air inlet corresponds to the compressor 13, that is, the air entering from the front side is first 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 is also guided to the condenser 16 to help the condenser 16 dissipate heat. This can make the air flow more reasonable, different components can obtain cooling air as needed, thereby improving the heat dissipation efficiency of the system, and can also reduce the turbulent flow of air in the system and reduce energy consumption.

[0065] Since the compressor 13 generates a large amount of heat, in some embodiments, the air baffle 111 is provided with an adjusting plate, which can be used to adjust the position of the air baffle 111. The adjusting plate can include a motor and an adjuster. The motor provides power to drive the adjuster to change the position of the air baffle 111. The adjuster is connected to the motor and the air baffle 111, and adjusts the position of the air baffle 111 according to the driving of the motor.

[0066] The controller is configured to:

[0067] Obtain a temperature result detected by a temperature sensor;

[0068] If the temperature result is greater than or equal to a temperature threshold, send an instruction to the motor to control the motor to drive the adjuster to adjust the position of the air baffle 111.

[0069] That is, when the temperature reaches or exceeds the set threshold, the controller starts the motor, and then adjusts the position of the air baffle 111 through the adjuster to increase the area of the first air inlet. The larger air inlet can allow more air to flow into the compressor 13 area, thereby improving the air flow rate and carrying away more heat, thereby improving the heat dissipation efficiency of the system.

[0070] In some embodiments, the water pan 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 pan 14 and used to fix the fan assembly 15 and the condenser 16. In this embodiment, the structure of the first island 141 and the second island 142 is not limited.

[0071] Since the water tray 14 is used to receive condensed water, the height of the first island 141 and the second island 142 is higher than the height of the water tray 14 in the full water state, that is, even if the water tray 14 is filled with condensed water, the fan assembly 15 and the condenser 16 will not be soaked with water, ensuring normal operation.

[0072] In some embodiments, splash-proof baffles can 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 rear cover 12, and soft sealing strips are attached around the ventilation holes to form a closed air field to ensure that the air flows along the expected path.

[0074] For example, air enters from the air inlet 21 on the front side of the bottom plate 11, exchanges heat 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 air flow into the air duct air inlet 1731, the fan cover 173 covers the fan 172 and forms a volute structure with the fan seat 171, the air flow smoothly flows in the volute, and the air flow is discharged to the outside of the cabinet through the air duct air outlet 174 on the rear cover 12 and the ventilation holes.

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

[0076] Air enters from the air inlet 21 on the bottom plate 11, exchanges heat 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 air flow into the air duct air inlet 1731, and is discharged to the bottom chamber 3 through the ventilation holes, and the discharged hot air is discharged to the outside of the refrigerator 2 through the recess 230 on the back plate 23.

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

It can be understood that the refrigeration system, the cooling system and the control system comprise specific components that can achieve the above-mentioned functions.

[0079] In some embodiments, the refrigeration system comprises a compressor, a condenser, an evaporator and a throttling device. The compressor is used to compress refrigerant gas to increase pressure and temperature, thereby driving the refrigerant to flow in the system. During the compression process, the refrigerant changes from low-pressure high-temperature gas to high-pressure high-temperature gas, thereby generating a refrigeration effect. The condenser is used to cool the high-temperature high-pressure gas discharged by the compressor into a liquid state. The refrigerant gas is converted into a liquid state by releasing heat through the heat sink, and is ready for 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 gaseous state in the evaporator, absorbs heat from the surrounding environment, thereby achieving the purpose of reducing the temperature inside the refrigerator. The throttling device can comprise an expansion valve and a capillary tube, which is used to adjust the flow of refrigerant, reduce its pressure, and make it into a low-temperature low-pressure gas-liquid mixed state, ready for entering the evaporator.

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