Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a control method and device for a refrigerator and a refrigerator. Background Art

[0002] To meet the needs of merchants, some manufacturers offer refrigerators with adjustable heating and cooling functions. These refrigerators are typically single-compartment commercial stand-up units. They can adapt to the cooling or heating needs of different products, such as using heating in winter or cooling in summer, depending on the season.

[0003] However, the refrigerators in the related art can only realize the conversion between the cooling function and the heating function of a single room. Therefore, the functions are relatively limited and the flexibility is low.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0006] The embodiments of the present disclosure provide a control method and device for a refrigerator, and the refrigerator, which can enhance the diversity of refrigerator functions, improve the flexibility of the refrigerator, and enhance the user experience of the refrigerator.

[0007] In some embodiments, a control method for a refrigerator is provided, the refrigerator comprising a first compartment, a second compartment, a heating compartment, and an evaporator compartment; the heating compartment is configured to deliver hot air to the first compartment and / or the second compartment via an air duct assembly; the evaporator compartment is configured to deliver cold air to the first compartment and / or the second compartment via the air duct assembly; the control method comprises: in response to a mode switching request, obtaining a target compartment and a target operating mode corresponding to the mode switching request; obtaining current operating modes of the first compartment and the second compartment; determining a target clearance state of the air duct assembly based on the current operating mode and the target operating mode; and controlling the air duct assembly based on the target clearance state.

[0008] In some embodiments, a control device for a refrigerator is provided, comprising a processor and a memory storing program instructions, wherein the processor is configured to execute the control method for the refrigerator as described in the above embodiments when running the program instructions.

[0009] In some embodiments, a refrigerator is provided, comprising: a housing comprising a first compartment, a second compartment, a heating compartment, and an evaporator compartment; an air duct assembly connecting the first compartment, the second compartment, the heating compartment, and the evaporator compartment; wherein the heating compartment is used to transport hot air to the first compartment and / or the second compartment via the air duct assembly, and the evaporator compartment is used to transport cold air to the first compartment and / or the second compartment via the air duct assembly; and a control device for the refrigerator as described in the above embodiment is mounted on the housing and is in communication with the air duct assembly.

[0010] The control method, device, and refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects:

[0011] The cabinet of the refrigerator provided by the embodiment of the present disclosure is defined as having two storage compartments, a first compartment and a second compartment, which increases the number of storage compartments compared to the related art. Since the heating compartment can transport hot air to the first compartment and / or the second compartment through the air duct assembly, and the evaporator compartment can transport cold air to the first compartment and / or the second compartment through the air duct assembly, the refrigerator in the present application can realize that when both the first compartment and the second compartment are operating in cooling mode or heating mode, the first compartment operates in cooling mode while the second compartment operates in heating mode, or the first compartment operates in heating mode while the second compartment operates in cooling mode. Compared with the related art that can only realize the conversion between the cooling function and the heating function of a single compartment, the present application has more working states, enriching the diversity of the refrigerator's functions.

[0012] In addition, the control method provided by the embodiment of the present disclosure can respond to the user's mode switching request, obtain the target compartment and target operating mode corresponding to the mode switching request, and obtain the current operating mode of the first compartment and the second compartment. Then, based on the current operating mode and the target operating mode, the target clearance state of the air duct component is determined, and the air duct component is controlled so that the target compartment can operate in the target operating mode to meet the user's needs. Compared with the related art that can only realize the conversion of the cooling function and heating function of a single compartment, the present application can simultaneously control the air duct component, so that the corresponding operating mode conversion between the first compartment and the second compartment is carried out according to the user's needs, thereby improving the diversity of the refrigerator's functions, improving the flexibility of the refrigerator and improving the user experience of the refrigerator.

[0043] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0044] The refrigerator 1 provided in the embodiment of the present disclosure is as follows: Figures 1 to 4 As shown, the refrigerator 1 includes a housing 10, an air duct assembly 40, and a control device 70 for the refrigerator. The housing 10 includes a first compartment 120, a second compartment 130, a heating compartment 110, and an evaporator compartment 140. The air duct assembly 40 connects the first compartment 120, the second compartment 130, the heating compartment 110, and the evaporator compartment 140. The heating compartment 110 is used to deliver hot air to the first compartment 120 and / or the second compartment 130 through the air duct assembly 40, and the evaporator compartment 140 is used to deliver cold air to the first compartment 120 and / or the second compartment 130 through the air duct assembly 40. The control device 70 for the refrigerator is mounted on the housing 10 and is in communication with the air duct assembly 40.

[0045] The housing 10 of the refrigerator 1 provided in the embodiment of the present disclosure defines two storage compartments, a first compartment 120 and a second compartment 130. Compared with the related art, the number of storage compartments is increased, thereby improving the storage flexibility and storage space utilization of the refrigerator 1. Since the heating compartment 110 can deliver hot air to the first compartment 120 and / or the second compartment 130 through the air duct assembly 40, and the evaporator compartment 140 can deliver cold air to the first compartment 120 and / or the second compartment 130 through the air duct assembly 40, the refrigerator 1 in the present application can realize that when both the first compartment 120 and the second compartment 130 are operating in cooling mode or heating mode, the first compartment 120 is operating in cooling mode while the second compartment 130 is operating in heating mode, or the first compartment 120 is operating in heating mode while the second compartment 130 is operating in cooling mode. Compared with the related art that can only realize the conversion between the cooling function and the heating function of a single compartment, the present application has more working states, enriching the diversity of the functions of the refrigerator 1.

[0046] Optionally, combined Figures 1 to 4 As shown, the refrigerator 1 further includes a heating assembly 20 and an evaporator 30. The heating assembly 20 is disposed in the heating compartment 110. The evaporator 30 is disposed in the evaporator compartment 140.

[0047] In this embodiment, a heater 210 is provided in the heating compartment 110 for generating hot air, and an evaporator 30 is provided in the evaporator compartment 140 for generating cold air.

[0048] Optionally, combined Figures 1 to 5 As shown, the air duct assembly 40 includes a main air duct 410 and a main damper 420. The opposite ends of the main air duct 410 are connected to the heating chamber 110 and the evaporator chamber 140, respectively. A first vent 412 and a second vent 414 are spaced apart along the main air duct 410. The first vent 412 connects the first compartment 120 to the main air duct 410, while the second vent 414 connects the second compartment 130 to the main air duct 410. The main damper 420 is disposed in the main air duct 410 and is located between the first vent 412 and the second vent 414.

[0049] The refrigerator 1 provided in the embodiment of the present disclosure is provided with a main air duct 410 connected to the heating compartment 110 and the evaporator compartment 140. The main air duct 410 includes a first vent 412 for communicating with the first compartment 120 and a second vent 414 for communicating with the second compartment 130, so as to guide cold air or hot air into the first compartment 120 and / or the second compartment 130. A main damper 420 is provided between the first vent 412 and the second vent 414 to control the main air duct 410 to achieve different conduction states, thereby controlling the flow direction of cold air and / or hot air and realizing different operating modes.

[0050] Specific, combined Figure 1 As shown (the arrow in the figure indicates the direction of air flow), when the main air door 420 is open, the first chamber 120 and the second chamber 130, the heating chamber 110 and the evaporator chamber 140 are connected, the heating component 20 is turned off, and the evaporator 30 is turned on to generate cold air. The cold air passes through the main air duct 410, enters the first chamber 120 through the first vent 412, and enters the second chamber 130 through the second vent 414, so that both the first chamber 120 and the second chamber 130 are cooled. Specifically, combined with Figure 2 As shown (the arrow in the figure indicates the direction of air flow), when the main air door 420 is open, the first chamber 120 and the second chamber 130, the heating chamber 110 and the evaporator chamber 140 are connected, the evaporator 30 is turned off, and the heating component 20 is turned on to generate hot air. The hot air passes through the main air duct 410, enters the second chamber 130 through the second vent 414, and enters the first chamber 120 through the first vent 412, so that both the first chamber 120 and the second chamber 130 are heated. Specifically, combined with Figure 3As shown (the arrows in the figure indicate the direction of air flow), when the main damper 420 is closed, the first chamber 120 and the second chamber 130, the heating chamber 110 and the evaporator chamber 140 are not connected, and the heating assembly 20 and the evaporator 30 are turned on to generate hot air and cold air, respectively. Among them, the cold air enters the first chamber 120 through the first vent 412 through the main air duct 410, and the hot air enters the second chamber 130 through the second vent 414 through the main air duct 410, so that the refrigerator 1 can achieve both cooling and heating.

[0051] Compared with related technologies, the refrigerator 1 of the present application can not only achieve uniform cooling or uniform heating, but also achieve simultaneous cooling and heating, thereby improving the functional diversity and usage flexibility of the refrigerator 1, so that the refrigerator 1 can maintain ideal storage conditions under different ambient temperatures, expanding its scope of application and improving the user experience.

[0052] Optionally, combined Figures 1 to 4 As shown, the housing 10 further includes a compressor compartment 170. The compressor compartment 170 is disposed adjacent to the evaporator compartment 140. The refrigerator 1 further includes a compressor 60. The compressor 60 is disposed in the compressor compartment 170 and is connected to the evaporator 30.

[0053] In this embodiment, compressor 60 is located in compressor compartment 170 and is connected to evaporator 30 to provide low-temperature, low-pressure refrigerant to evaporator 30. The liquid refrigerant in evaporator 30 rapidly evaporates, absorbing heat. The air passing through evaporator 30 cools down and becomes cold air, thereby generating cold air. Therefore, by controlling the start and stop of compressor 60, the operating state of evaporator 30 can be controlled, thereby controlling the generation and stopping of cold air.

[0054] It should be noted that turning on the evaporator 30 in this application actually means turning on the compressor 60 to supply low-temperature, low-pressure refrigerant to the evaporator 30, so that the air passing through the evaporator 30 is cooled and becomes cold air. Turning off the evaporator 30 in this application actually means turning off the compressor 60 to stop supplying low-temperature, low-pressure refrigerant to the evaporator 30, so that the temperature of the air passing through the evaporator 30 remains unchanged.

[0055] Optionally, combined Figures 1 to 4 As shown, along the height direction of the box body 10, the heating chamber 110, the first chamber 120, the second chamber 130 and the evaporator chamber 140 are sequentially arranged from top to bottom.

[0056] In this embodiment, along the height direction of the refrigerator 1, the first compartment 120 is located above the second compartment 130, and the heating compartment 110 is disposed above the first compartment 120. By limiting the positions of the heating compartment 110 and the evaporator compartment 140 to opposite ends of the housing 10, the heating compartment 110 and the evaporator compartment 140 are prevented from being too close together. The hot air generated in the heating compartment 110 and the cold air generated in the evaporator compartment 140 exchange heat, thereby offsetting each other.

[0057] Optionally, combined Figure 5 and Figure 6 As shown, the air duct assembly 40 further includes an auxiliary air duct 430 and an auxiliary damper 440. The auxiliary air duct 430 is connected to the first chamber 120 and the second chamber 130 at opposite ends thereof. The main air duct 410 and the auxiliary air duct 430 are spaced apart and arranged in the housing 10. The auxiliary damper 440 is arranged in the auxiliary air duct 430.

[0058] In this embodiment, the opposite ends of the auxiliary air duct 430 are connected to the first chamber 120 and the second chamber 130, respectively. The auxiliary air duct 430 is used to assist the main air duct 410 in controlling the temperature of the refrigerator 1. Specifically, when the first chamber 120 and the second chamber 130 of the refrigerator 1 are both cooling or heating, the auxiliary air duct 430 can be used to directly connect the first chamber 120 and the second chamber 130, thereby providing an additional air circulation path and balancing the temperature between the two chambers. By providing an auxiliary damper 440 in the auxiliary air duct 430 to regulate the air flow within the auxiliary air duct 430, the auxiliary air duct 430 cooperates with the main air duct 410 and the auxiliary damper 440 to achieve temperature regulation of the refrigerator 1.

[0059] For example, along the height direction of the box body 10, the heating chamber 110, the first chamber 120, the second chamber 130 and the evaporator chamber 140 are sequentially arranged from top to bottom. Figure 1 and Figure 5 As shown, when both the first chamber 120 and the second chamber 130 of the refrigerator 1 are refrigerated, the amount of cold air entering the first chamber 120 through the main air duct 410 and / or the auxiliary air duct 430 is controlled by adjusting the opening of the main air door 420 and / or the auxiliary air door 440 to achieve temperature control of the first chamber 120. Figure 2 and Figure 5 As shown, when both the first chamber 120 and the second chamber 130 of the refrigerator 1 are heated, the amount of hot air entering the second chamber 130 through the main air duct 410 and / or the auxiliary air duct 430 is controlled by adjusting the opening of the main air door 420 and / or the auxiliary air door 440, so as to achieve temperature control of the second chamber 130. Figure 3 and Figure 5As shown, when the first chamber 120 is heating and the second chamber 130 is cooling, the main damper 420 and the auxiliary damper 440 are closed, so that hot air enters the first chamber 120 through the main air duct 410, and cold air enters the second chamber 130 through the main air duct 410. There is no electrical connection between the first chamber 120 and the second chamber 130 to ensure temperature stability of the first chamber 120 and / or the second chamber 130.

[0060] Optionally, combined Figure 5 and Figure 6 As shown, there are two main air ducts 410, which are symmetrically arranged on the housing 10. There are two main air dampers 420, which are arranged in a one-to-one correspondence with the two main air ducts 410. The auxiliary air duct 430 is located between the two main air ducts 410.

[0061] In this embodiment, the symmetrical layout of the two main air ducts 410 enables the cold air or hot air to be evenly distributed to every corner of the refrigerator 1, thereby improving the uniformity of temperature control. At the same time, by increasing the number of main air ducts 410, the ventilation efficiency of the refrigerator 1 is increased, ensuring that the gas circulation is more rapid, and improving the cooling and / or heating efficiency of the refrigerator 1. The two main air doors 420 and the two main air ducts 410 are arranged in a one-to-one correspondence, making it more flexible to control the direction of air flow. The auxiliary air duct 430 is located between the two main air ducts 410, and plays the role of supplementing and guiding the air flow to further optimize the air circulation, ensuring that the cold air or hot air can fully cover the entire interior of the refrigerator 1, and helping to improve the cooling or heating effect, so that the refrigerator 1 performs better in different working modes.

[0062] Optionally, combined Figures 1 to 5 As shown, there are multiple first vents 412, which are evenly spaced and distributed along the extension direction of the main air duct 410. The multiple first vents 412 are used to connect the first chamber 120 and the main air duct 410. There are multiple second vents 414, which are evenly spaced and distributed along the extension direction of the main air duct 410. The multiple second vents 414 are used to connect the second chamber 130 and the main air duct 410.

[0063] In this embodiment, by increasing the number of the first vents 412 and the second vents 414, the cold air or hot air can be further evenly distributed to every corner of the cold cabinet 1, thereby improving the uniformity of temperature control, and at the same time accelerating the exchange rate of gas between the main air duct 410 and the first chamber 120 and / or the second chamber 130, thereby improving the cooling and / or heating efficiency of the cold cabinet 1.

[0064] Optionally, combined Figure 5 and Figure 6As shown, the air duct assembly 40 further includes a first turning damper 450 and a second turning damper 460. The first turning damper 450 is provided at the connection between one of the two main air ducts 410 and the heating chamber 110, and the second turning damper 460 is provided at the connection between the other of the two main air ducts 410 and the evaporator chamber 140.

[0065] Combine Figure 6 As shown, to facilitate distinguishing the two main air ducts 410, the following embodiment names the two main air ducts 410 as a first air duct 416 and a second air duct 418, respectively. The two main dampers 420 are named a first damper 426 and a second damper 428, respectively. The first damper 426 is disposed in the first air duct 416 and is located between the first compartment 120 and the second compartment 130. The second damper 428 is disposed in the second air duct 418 and is located between the first compartment 120 and the second compartment 130. A first turning damper 450 is disposed at the connection between the first air duct 416 and the heating chamber 110, and a second turning damper 460 is disposed at the connection between the second air duct 418 and the evaporator chamber 140.

[0066] It can be understood that the air duct assembly 40 includes a first air duct 416, a second air duct 418, a first damper 426, a second damper 428, a first turning damper 450, and a second turning damper 460. The first air duct 416 and the second air duct 418 are spaced apart and symmetrically arranged. The first air duct 416 connects the first compartment 120, the second compartment 130, the heating compartment 110, and the evaporator compartment 140, while the second air duct 418 connects the first compartment 120, the second compartment 130, the heating compartment 110, and the evaporator compartment 140. The first damper 426 is disposed in the first air duct 416 between the first compartment 120 and the second compartment 130, while the second damper 428 is disposed in the second air duct 418 between the first compartment 120 and the second compartment 130. The first turning damper 450 is disposed at a connection point between the first air duct 416 and the heating chamber 110 , and the second turning damper 460 is disposed at a connection point between the second air duct 418 and the evaporator chamber 140 .

[0067] In this embodiment, a first and second turning dampers 450, 460 are added to control the connection between the first air duct 416 and the heating chamber 110, and the connection between the second air duct 418 and the evaporator chamber 140, so that the first and second air ducts 416, 418 can be used as cooling or heating ducts, respectively. Specifically, when the first and second turning dampers 450, 460 are closed, the first air duct 416 connects to the first and second chambers 120, 130, and the evaporator chamber 140, allowing the first air duct 416 to function as a cooling duct. Simultaneously, the second air duct 418 connects to the heating chamber 110, the first and second chambers 120, 130, allowing the second air duct 418 to function as a heating duct. The first air duct 416 and the second air duct 418 are used as cooling air ducts or heating air ducts respectively to avoid the cold air or hot air previously trapped in the main air duct 410 affecting the operation of the refrigerator 1 during the conversion of the cooling or heating function, thereby increasing the energy consumption of the refrigerator 1.

[0068] Optionally, combined Figure 7 and Figure 8 As shown (the arrow in the figure indicates the direction of air flow), the air duct assembly 40 also includes an air guide plate 470. The air guide plate 470 is disposed at the first vent 412 and / or the second vent 414. Along the extension direction of the main air duct 410, the plane on which the air guide plate 470 is located is inclined toward the direction of the evaporator compartment 140.

[0069] In this embodiment, the wind deflector 470 is tilted so that the plane on which the wind deflector 470 is located is tilted toward the evaporator compartment 140, thereby guiding the hot air flow toward the evaporator compartment 140. Specifically, when the freezer 1 is operating the defrost function, the tilted wind deflector 470 optimizes the hot air transfer path, allowing the hot air flow to flow more concentratedly toward the evaporator compartment 140, defrosting the evaporator 30 and improving the defrost efficiency of the freezer 1. At the same time, because the wind deflector 470 is disposed at the first vent 412 and / or the second vent 414, it serves as a guide, allowing the cold air flow flowing out of the evaporator compartment 140 to enter the first chamber 120 and / or the second chamber 130 more smoothly, thereby improving the cooling efficiency of the freezer 1. In addition, by tilting the air guide plate 470, it helps to reduce the turbulence and resistance of the air flow, so that the air flow flows more stably through the first vent 412 and / or the second vent 414, as well as the main air duct 410, thereby preventing the confusion and blockage of the air flow and ensuring the circulation effect of the air inside the refrigerator 1.

[0070] Optionally, combined Figure 8 As shown, the angle between the plane where the air guide plate 470 is located and the plane where the first vent 412 and / or the second vent 414 are located is θ, where 30°≤θ≤60°.

[0071] A smaller angle helps to more directly and centrally guide the hot air flow toward the evaporator compartment 140. A larger angle helps to more directly and centrally guide the cold air flow into the first compartment 120 and / or the second compartment 130. In this embodiment, by limiting the angle θ between the plane where the air guide plate 470 is located and the plane where the first vent 412 and / or the second vent 414 are located to satisfy 30°≤θ≤60°, the transfer efficiency of cold air or hot air is optimized, so that the air guide plate 470 can not only guide the cold air flow or hot air flow, but also ensure the relatively smooth flow of the air flow on the air guide plate 470, prevent turbulence, improve the stable flow of the air flow in the main air duct 410, and improve the refrigeration or defrosting efficiency of the refrigerator 1.

[0072] Illustratively, the angle θ between the plane where the air guide plate 470 is located and the plane where the first vent 412 and / or the second vent 414 are located is 30°, 40°, 45°, 50° or 60°.

[0073] Optionally, the air guide plate 470 includes a rubber air guide plate 470 or a silicone air guide plate 470 .

[0074] The rubber air guide plate 470 or the silicone air guide plate 470 has high softness, elasticity, high and low temperature resistance, corrosion resistance and wear resistance. In this embodiment, the high softness and elasticity of the rubber air guide plate 470 or the silicone air guide plate 470 are utilized to enable the air guide plate 470 to better adapt to the shape and surface characteristics of the first vent 412 and / or the second vent 414. In addition, the high softness and elasticity of the rubber air guide plate 470 or the silicone air guide plate 470 can further enhance the airflow guiding effect of the air guide plate 470. Specifically, in combination with Figure 9 As shown, since the air deflector 470 is disposed at the first vent 412 and / or the second vent 414, and the plane on which the air deflector 470 is located is inclined toward the evaporator compartment 140, when the refrigerator 1 is defrosting the evaporator, the hot air generated in the heating compartment 110 flows along the main air duct 410 to the evaporator compartment 140. Under the action of the hot air flow pressure, the rubber air deflector 470 or the silicone air deflector 470 rotates relative to the main air duct 410 to close the first vent 412 and / or the second vent 414. The softness of the rubber air guide plate 470 or the silicone air guide plate 470 helps to make the air guide plate 470 fit tightly with the first vent 412 and / or the second vent 414, so that the main air duct 410 is directly connected to the heating chamber 110 and the evaporator chamber 140, and the hot air enters the evaporator chamber 140 directly through the main air duct 410, avoiding the hot air flow from entering the first chamber 120 through the first vent 412 and / or entering the second chamber 130 through the second vent 414, effectively preventing air leakage and energy loss, thereby improving the defrosting efficiency of the refrigerator 1.

[0075] The high and low temperature resistance of the rubber air guide plate 470 or the silicone air guide plate 470 can maintain stable physical properties within a wide temperature range, so that the air guide plate 470 can withstand the test of temperature changes during cooling and heating, is not easily deformed or aged, and maintains a long service life. The temperature adaptability of the rubber air guide plate 470 or the silicone air guide plate 470 is utilized to improve the stability and reliability of the refrigerator 1. The corrosion resistance and wear resistance of the rubber air guide plate 470 or the silicone air guide plate 470 are utilized to enable the air guide plate 470 to adapt to humid or corrosive environments and not be easily damaged by the external environment, further improving the service life of the air guide plate 470. At the same time, the wear resistance of the rubber air guide plate 470 or the silicone air guide plate 470 helps to reduce the wear caused by the friction of the air flow on the air guide plate 470, maintain the long-term stability of the air guide plate 470, and further improve the service life of the air guide plate 470.

[0076] Optionally, combined Figure 7 and Figure 8 As shown, there are multiple air guide plates 470 , and along the extension direction of the main air duct 410 , the multiple air guide plates 470 are spaced apart at the first ventilation opening 412 and / or the second ventilation opening 414 .

[0077] In this embodiment, there are multiple air guide plates 470. By increasing the number of air guide plates 470, the guiding effect of the main air duct 410 on the hot air flow or the cold air flow is further improved, thereby improving the defrosting or cooling efficiency of the refrigerator 1.

[0078] Optionally, combined Figures 1 to 9 As shown (the arrow in the figure indicates the direction of air flow), the refrigerator 1 also includes a door body 50. The door body 50 is rotatably mounted on the housing 10 and is used to open or close the first chamber 120 and the second chamber 130. The air duct assembly 40 also includes a guide air duct 480 and a guide air door 490. One end of the guide air duct 480 is connected to the heating chamber 110, and the other end of the guide air duct 480 is connected to the first chamber 120 and is located in the first chamber 120 near the door body 50. The guide air door 490 is disposed at the end of the guide air duct 480 that is connected to the first chamber 120.

[0079] In this embodiment, the door 50 is rotatably mounted on the housing 10. One end of the guide air duct 480 is connected to the heating chamber 110, and the other end is connected to the first chamber 120. The guide air duct 480 is located in the first chamber 120 near the door 50, so that the refrigerator 1 can directly guide the gas in the heating chamber 110 to the door 50 to remove dew from the door 50. The guide air door 490 is located at one end of the guide air duct 480 connected to the first chamber 120. By controlling the open and close state of the guide air door 490, the distribution of cold air or hot air in the first chamber 120 can be adjusted, achieving more precise temperature regulation and enabling or disabling the dew removal function of the refrigerator 1.

[0080] Optionally, combined Figure 7 and Figure 8 As shown, along the height direction of the cabinet 10, a front air port 482 and a rear air port 484 are spaced apart at one end of the guide air duct 480 near the door 50. Along the depth direction of the cabinet 10, the distance from the front air port 482 to the door 50 is smaller than the distance from the rear air port 484 to the door 50. There are two guide air doors 490, which are spaced apart from each other, respectively, at the front air port 482 and the rear air port 484.

[0081] In this embodiment, a front air outlet 482 and a rear air outlet 484 are spaced apart at one end of the guide air duct 480 close to the door body 50, and the distance from the front air outlet 482 to the door body 50 is smaller than the distance from the rear air outlet 484 to the door body 50. Figure 8 As shown (the arrow in the figure indicates the direction of air flow), the distance from the front air outlet 482 to the door body 50 is a, and the distance from the rear air outlet 484 to the door body 50 is b, then a<b. By setting the air outlet distribution of the guide air duct 480 and providing guide air doors 490 at both the front air outlet 482 and the rear air outlet 484, the direction of the air flow can be precisely controlled to meet the various functional requirements of the refrigerator 1. Specifically, when the refrigerator 1 is dehumidifying the door body 50, the rear air outlet 484 is closed and the front air outlet 482 is opened, so that the refrigerator 1 can directly guide the gas in the heating chamber 110 to the door body 50 to quickly dehumidify the door body 50. Specifically, when the first chamber 120 is cooled or heated, the rear air vents 484 are opened and the front air vents 482 are closed, so that the hot air flow or the hot air flow can be evenly distributed in the first chamber 120 through the rear air vents 484, thereby facilitating rapid heating or cooling of the first chamber 120.

[0082] Optionally, combined Figure 3 、 Figure 4 and Figure 10As shown, the guide air door 490 includes a swing blade mechanism 492. The swing blade mechanism 492 is disposed at one end of the guide air duct 480 that connects to the first chamber 120. The swing blade mechanism 492 can rotate relative to the guide air duct 480 to change the direction of the airflow flowing from the guide air duct 480 into the first chamber 120.

[0083] In this embodiment, the guide door 490 includes a swing blade mechanism 492, and the swing blade mechanism 492 can rotate relative to the guide air duct 480 to change the direction of the air flow from the guide air duct 480 into the first chamber 120, so that the cold air or hot air can flow to a specific area in a targeted manner, thereby meeting various functional requirements of the refrigerator 1. For example, in combination with Figure 3 and Figure 10 As shown (the arrow in the figure indicates the direction of air flow), when the swing blade mechanism 492 rotates to the first position relative to the guide air duct 480, the air flow direction flowing out of the swing blade mechanism 492 is inclined toward the bottom of the refrigerator body 10, so that the air flow is quickly distributed inside the first chamber 120, so as to quickly heat or cool the first chamber 120. For example, combined with Figure 4 and Figure 10 As shown (the direction indicated by the arrow in the figure is the direction of air flow), when the swing blade mechanism 492 rotates to the second position relative to the guide air duct 480, the direction of the air flow flowing out through the swing blade mechanism 492 is inclined toward the top of the refrigerator body 10, so that the air flow is reflected by the top of the refrigerator body 10 and forms an air flow on the side of the door body 50 in the first chamber 120 to remove dew from the door body 50.

[0084] Optionally, combined Figure 10 As shown, the swing blade mechanism 492 includes a plurality of swing blades 494, a connecting rod 496, and a telescopic motor 498. Along the height direction of the housing 10, the plurality of swing blades 494 are spaced apart at one end of the guide air duct 480 connected to the first chamber 120 and are rotatably connected to the guide air duct 480. The swing blades 494 are provided with through holes. The connecting rod 496 is passed through the through holes and is connected to the plurality of swing blades 494. The telescopic motor 498 is fixedly provided on the housing 10, and the output shaft of the telescopic motor 498 is connected to one end of the connecting rod 496. The telescopic motor 498 is used to drive the connecting rod 496 to move along the height direction of the housing 10, thereby driving the plurality of swing blades 494 to rotate relative to the guide air duct 480.

[0085] In this embodiment, the swing blades 494 are provided with through holes, and the connecting rods 496 are provided through the through holes and connected to the plurality of swing blades 494, so that the swing blades 494 can be connected to each other via the connecting rods 496 to form an integral control unit. This allows the movement of the swing blades 494 to be coordinated and synchronously controlled, ensuring the coordinated operation of the swing blades 494, thereby improving the accuracy and reliability of the louver mechanism in regulating the direction of airflow. In addition, the output shaft of the telescopic motor 498 is connected to one end of the connecting rod 496. The telescopic motor 498 is used to drive the connecting rod 496 to move along the height direction of the cabinet 10, thereby driving the plurality of swing blades 494 to rotate relative to the guide duct 480, so that airflow regulation can be performed along the height direction of the refrigerator 1, so as to meet the requirements of dehumidification of the door 50 of the refrigerator 1, or rapid cooling or heating of the first chamber 120.

[0086] Optionally, the main damper 420 includes a rotary motor 422 and a guide vane 424. The rotary motor 422 is disposed in the main air duct 410. The guide vane 424 is connected to the output shaft of the rotary motor 422. The rotary motor 422 is configured to drive the guide vane 424 to rotate relative to the main air duct 410 to achieve different opening states of the main damper 420.

[0087] In this embodiment, the guide vanes 424 are connected to the output shaft of the rotary motor 422. Driven by the rotary motor 422, the guide vanes 424 can rotate relative to the main air duct 410 to achieve different opening states of the main damper 420, thereby meeting the different functional requirements of the refrigerator 1. Specifically, the rotary motor 422 is used to drive the guide vanes 424 to rotate relative to the main air duct 410. By controlling the operation of the rotary motor 422, the angle of the guide vanes 424 can be adjusted, thereby changing the ventilation state of the main air duct 410, thereby meeting the different functional requirements of the refrigerator 1.

[0088] Optionally, the specific structures of the auxiliary damper 440 , the first turning damper 450 and the second turning damper 460 are the same as those of the main damper 420 , and are not described in detail here.

[0089] Optionally, a main damper 420 or a guide damper 490 is provided at the first vent 412 to open or close the first vent 412. A main damper 420 or a guide damper 490 is provided at the second vent 414 to open or close the second vent 414.

[0090] In this embodiment, a main damper 420 or a guide damper 490 is provided at the first vent 412 to achieve controlled opening or closing of the first vent 412. A main damper 420 or a guide damper 490 is provided at the second vent 414 to achieve controlled opening or closing of the second vent 414. This, in conjunction with the first and second steering dampers 450 and 460, allows the refrigerator 1 to operate in a cooling mode in which the first compartment 120 is cooled and the second compartment 130 is heated. For example, along the height of the cabinet 10, the heating compartment 110, the first compartment 120, the second compartment 130, and the evaporator compartment 140 are sequentially spaced from top to bottom. Guide dampers 490 are provided at both the first and second vents 412 and 414. A first reversing damper 450 is provided at the connection between the first air duct 416 and the heating compartment 110, and a second reversing damper 460 is provided at the connection between the second air duct 418 and the evaporator compartment 140. When the refrigerator 1 is cooling the first compartment 120 and heating the second compartment 130, the first and second reversing dampers 450 and 460 are closed, the second vent 414 on the first air duct 416 is closed, and the first vent 412 on the first air duct 416 is opened, so that the first air duct 416 connects the first compartment 120 and the evaporator compartment 140. Consequently, the cold air in the evaporator compartment 140 enters the first compartment 120 through the first air duct 416 and the first vent 412, thereby cooling the first compartment 120. At the same time, the second vent 414 on the second air duct 418 is opened, and the first vent 412 on the second air duct 418 is closed, so that the second air duct 418 connects the second chamber 130 and the heating chamber 110, and the hot air in the heating chamber 110 enters the second chamber 130 through the second air duct 418 and the second vent 414, thereby heating the second chamber 130.

[0091] Compared with related technologies, the refrigerator 1 of the present application can not only achieve uniform cooling or uniform heating, but also achieve cooling of the first chamber 120 and heating of the second chamber 130, or heating of the first chamber 120 and cooling of the second chamber 130, further improving the functional diversity and flexibility of the refrigerator 1, so that the refrigerator 1 can maintain ideal storage conditions under different ambient temperatures, further expanding the scope of application of the refrigerator 1 and improving the user experience.

[0092] Optionally, combined Figures 1 to 4 As shown, the evaporator compartment 140 is provided with an air outlet 142, which is used to connect the second chamber 130 and the evaporator compartment 140. A third damper 510 is provided at the air outlet 142.

[0093] The specific structure of the third damper 510 is the same as that of the main damper 420 and will not be repeated here.

[0094] In this embodiment, the third damper 510 is used to open or close the air supply port 142. By providing the air supply port 142 to connect the second compartment 130 and the evaporator compartment 140, the third damper 510 can be opened during the cooling process of the second compartment 130, thereby directly connecting the second compartment 130 and the evaporator compartment 140, thereby improving the cooling efficiency of the second compartment 130.

[0095] Furthermore, by providing a third damper 510 for opening or closing the air supply port 142 , the air supply port 142 is closed during the evaporator defrosting process of the refrigerator 1 , thereby preventing the hot air input into the evaporator compartment 140 from entering the second chamber 130 through the air supply port 142 and affecting the temperature of the second chamber 130 .

[0096] Optionally, combined Figures 1 to 4 As shown, the heating assembly 20 includes a heater 210 and a heating fan 220. The heating fan 220 is located around the heater 210. The heater 210 is used to heat the surrounding air to generate hot air.

[0097] In this embodiment, the heater 210 is used to heat the surrounding air to generate hot air, and a heating fan 220 is provided around the heater 210 to control the direction and velocity of the airflow in the heating chamber 110 so as to meet the functional requirements of the refrigerator 1. It is defined that during the rotation of the heating fan 220, the air in the heating chamber 110 flows along the extension direction of the guide air duct 480 toward the door body 50, and the heating fan 220 rotates in the forward direction; conversely, the heating fan 220 rotates in the reverse direction. For example, in the process of dehumidifying the door body 50 of the refrigerator 1, the heating fan 220 rotates in the forward direction so that the air in the heating chamber 110 flows along the extension direction of the guide air duct 480 toward the door body 50, so as to guide the air to the door body 50 and realize dehumidification of the door body 50. In addition, by increasing the rotation speed of the heating fan 220 to increase the air flow rate, the dehumidification efficiency of the door body 50 is thereby increased. For example, in combination with Figure 9 As shown, during evaporator defrosting of the refrigerator 1, the heating fan 220 rotates in the opposite direction, causing the air in the heating chamber 110 to flow along the extension direction of the guide duct 480 toward the side away from the door 50, thereby guiding the air to the main duct 410 and then to the evaporator chamber 140, thereby achieving evaporator defrosting. In addition, by increasing the speed of the heating fan 220, the air flow rate is increased, thereby improving the evaporator defrosting efficiency.

[0098] It should be noted that the specific positional relationship between the heater 210 and the heating fan 220, and the specific setting positions of the heater 210 and the heating fan 220 in the heating chamber 110 need to be specifically set by technical personnel based on the actual equipment products, and are not limited here.

[0099] Optionally, combined Figures 1 to 4As shown, the refrigerator 1 further includes a condensing fan 310 , which is disposed in the evaporator compartment 140 and located around the evaporator 30 .

[0100] In this embodiment, the condensing fan 310 is used to control the airflow direction and flow rate of the evaporator compartment 140, so that when the first chamber 120 and / or the second chamber 130 of the refrigerator 1 is cooled, the condensing fan 310 is used to regulate the cold air flow rate, thereby achieving the regulation of the cooling efficiency.

[0101] Optionally, the door body 50 includes a glass door body 50 or a foam door body 50 .

[0102] In this embodiment, the glass door 50 has high transparency. This allows for easy viewing of items stored within the refrigerator 1, enhancing the user experience. The foam door 50 also has excellent thermal insulation properties. This effectively reduces cold air leakage, thereby improving the thermal insulation performance of the refrigerator 1.

[0103] Optionally, combined Figures 1 to 4 As shown, the refrigerator 1 further includes a middle partition 150 and a sealing gasket 160. The middle partition 150 is disposed on the cabinet 10 and is used to cooperate with the cabinet 10 to define the first chamber 120 and the second chamber 130. The sealing gasket 160 is disposed at one end of the middle partition 150 near the door 50 and is used to seal the gap between the middle partition 150 and the door 50.

[0104] In this embodiment, a middle partition 150 cooperates with the housing 10 to define a first chamber 120 and a second chamber 130 , and a sealing gasket 160 is provided at one end of the middle partition 150 near the door 50 to seal the gap between the middle partition 150 and the door 50 , thereby preventing heat exchange between the first chamber 120 and the second chamber 130 through the gap between the middle partition 150 and the door 50 and causing energy consumption.

[0105] Optionally, the interior of the middle partition 150 is filled with foam or foaming material.

[0106] In this embodiment, foam or foaming material is filled inside the middle partition 150 to improve the thermal insulation performance of the middle partition 150, thereby preventing heat exchange between the first chamber 120 and the second chamber 130 and energy consumption.

[0107] Optionally, the control device 70 for the refrigerator includes a processor. The processor can, in response to a mode switching request, obtain a target compartment and a target operating mode corresponding to the mode switching request; obtain the current operating modes of the first compartment and the second compartment; determine a target clearance state of the air duct assembly based on the current operating mode and the target operating mode; and control the air duct assembly based on the target clearance state.

[0108] Combine Figure 11 As shown, the embodiment of the present disclosure provides a control method for a refrigerator, comprising:

[0109] S111 , in response to a mode switching request, the processor obtains a target compartment and a target operating mode corresponding to the mode switching request.

[0110] An interactive interface can be provided on the refrigerator door, through which the user switches the refrigerator's operating mode, generating a corresponding mode switch request signal. Alternatively, the user can switch the refrigerator's operating mode using an electronic device associated with the refrigerator, such as a smartphone, smart remote control, or smart wristband, generating a corresponding mode switch request signal. The mode switch request includes the target compartment and target operating mode to which the user wishes to switch. In this embodiment, the target compartment includes the first compartment and / or the second compartment. The operating modes include cooling mode and / or heating mode.

[0111] S112: The processor obtains the current operating modes of the first chamber and the second chamber.

[0112] S113, the processor determines the target clearance state of the air duct component according to the current operation mode and the target operation mode.

[0113] Optionally, determining a target clearance state of the air duct assembly according to the current operating mode and the target operating mode includes: when the target compartment is the first compartment and the target operating mode of the first compartment is different from the current operating mode, comparing the target operating mode of the first compartment with the current operating mode of the second compartment to obtain a first comparison result; and determining the target clearance state of the air duct assembly according to the first comparison result.

[0114] In this embodiment, the first compartment is located above the second compartment along the height of the refrigerator, and the heating chamber is located above the first compartment. When the target compartment is the first compartment, the target operating mode of the first compartment is compared with the current operating mode of the first compartment to determine whether the air duct assembly's clearance state needs to be adjusted. For example, if the first comparison result shows the two are the same (for example, the target operating mode and the current operating mode of the first compartment are both cooling mode or heating mode), the air duct assembly's clearance state does not need to be adjusted, and the current state can be maintained. If the two are different (for example, the current operating mode of the first compartment is cooling mode and the target operating mode is heating mode), the target operating mode of the first compartment is further compared with the current operating mode of the second compartment to obtain a first comparison result, thereby determining the target clearance state of the air duct assembly. By prioritizing the comparison of the target operating mode of the first compartment with the current operating mode of the first compartment, this embodiment aims to meet user needs in the most efficient manner and optimize energy consumption. At the same time, the interaction between the first and second compartments inside the freezer is considered to determine the target clearance state of the air duct components, so as to maximize the overall performance while maintaining the independence of the compartments.

[0115] Optionally, determining a target clearance state of the air duct assembly according to the first comparison result includes: when the first comparison result is that both the first chamber and the second chamber operate in the cooling mode or the heating mode, the target clearance state of the air duct assembly is the first clearance state; the first clearance state includes that the first air duct and the second air duct are both connected to the first chamber, the second chamber, the heating chamber and the evaporator chamber; when the first comparison result is that the first chamber operates in the cooling mode and the second chamber operates in the heating mode, the target clearance state of the air duct assembly is the second clearance state; the second clearance state includes that the first air duct is connected to the first chamber and the evaporator chamber, and the second air duct is connected to the second chamber and the heating chamber; when the first comparison result is that the first chamber operates in the heating mode and the second chamber operates in the cooling mode, the target clearance state of the air duct assembly is the third clearance state; the third clearance state includes that the first air duct and the second air duct are both connected to the first chamber and the heating chamber, the first air duct and the second air duct are both connected to the second chamber and the evaporator chamber, and there is no connection between the first chamber and the second chamber.

[0116] In this embodiment, a first air duct connects the first chamber, the second chamber, the heating chamber, and the evaporator chamber, while a second air duct connects the first chamber, the second chamber, the heating chamber, and the evaporator chamber, allowing air to flow between the first air duct and the first chamber, the second chamber, the heating chamber, and the evaporator chamber, and between the second air duct and the first chamber, the second chamber, the heating chamber, and the evaporator chamber. A target clearance state of the air duct assembly can be determined based on a comparison between the target operating mode of the first chamber and the current operating mode of the second chamber.

[0117] Specifically, if the first comparison result indicates that both the first and second chambers are operating in cooling or heating mode, the duct assembly should be in the first clear state. That is, both the first and second ducts are in communication with the first and second chambers, the heating chamber, and the evaporator chamber, allowing cool or hot air to flow freely between the first and second ducts, the first and second chambers, the heating chamber, and the evaporator chamber, achieving uniform cooling or heating. Specifically, if the first comparison result indicates that the first chamber is operating in cooling mode and the second chamber is operating in heating mode, the duct assembly should be in the second clear state. That is, the first duct is in communication only with the first chamber and the evaporator chamber, ensuring that cool air flows from the evaporator chamber into the first chamber through the first duct. Simultaneously, the second duct is in communication only with the second chamber and the heating chamber, ensuring that hot air flows from the heating chamber into the second chamber through the second duct. This allows the two chambers to operate independently in different modes without interfering with each other. Specifically, if the first comparison result indicates that the first compartment is operating in heating mode and the second compartment is operating in cooling mode, the duct assembly should be in the third clear state, meaning that both the first and second ducts are connected to the first compartment and the heating chamber, and both are connected to the second compartment and the evaporator chamber. However, there is no communication between the first and second compartments. This ensures that hot air enters the first compartment from the heating chamber through the first and second ducts, and cold air enters the second compartment from the evaporator chamber through the first and second ducts. At the same time, the two compartments operate independently in different modes without interfering with each other. By designing the clear states of the duct assembly, the refrigerator can flexibly control the temperature according to the needs of different compartments, ensuring that each compartment reaches the user's desired temperature while improving energy efficiency.

[0118] Optionally, determining the target clearance state of the air duct assembly according to the current operating mode and the target operating mode includes: when the target compartment is the second compartment and the target operating mode of the second compartment is different from the current operating mode, comparing the target operating mode of the second compartment with the current operating mode of the first compartment to obtain a second comparison result; and determining the target clearance state of the air duct assembly according to the second comparison result.

[0119] In this embodiment, along the height direction of the refrigerator, the first compartment is located above the second compartment, and the heating chamber is arranged above the first compartment. When the target compartment is the second compartment, the target operating mode of the second compartment is compared with the current operating mode of the second compartment to determine whether the clearance state of the air duct assembly needs to be adjusted. For example, if the second comparison result is the same (for example, the target operating mode and the current operating mode of the second compartment are both cooling mode or heating mode), the clearance state of the air duct assembly does not need to be adjusted, and the current state can be maintained. If the two are different (for example, the current operating mode of the second compartment is cooling mode and the target operating mode is heating mode), it is necessary to further compare the target operating mode of the second compartment with the current operating mode of the first compartment to obtain a second comparison result, and then determine the target clearance state of the air duct assembly. By prioritizing the comparison between the target operating mode of the second compartment and the current operating mode of the second compartment, this embodiment aims to meet user needs in the most efficient manner and optimize energy consumption. At the same time, the interaction between the second compartment and the first compartment inside the freezer is considered to determine the target clearance state of the air duct components, so as to maximize the overall performance while maintaining the independence of the compartments.

[0120] Optionally, determining the target clearance state of the air duct assembly according to the second comparison result includes: when the second comparison result shows that both the first and second chambers operate in cooling mode or heating mode, the target clearance state of the air duct assembly is the first clearance state; when the second comparison result shows that the first chamber operates in cooling mode and the second chamber operates in heating mode, the target clearance state of the air duct assembly is the second clearance state; when the second comparison result shows that the first chamber operates in heating mode and the second chamber operates in cooling mode, the target clearance state of the air duct assembly is the third clearance state.

[0121] In this embodiment, the content and function of determining the target clearance state of the air duct component according to the second comparison result are consistent with those of determining the target clearance state of the air duct component according to the first comparison result, and are not repeated here.

[0122] Optionally, determining a target clearance state of the air duct assembly according to the current operating mode and the target operating mode includes: when the target compartments are the first compartment and the second compartment, and the current operating modes of the first compartment and the second compartment are different from the target operating modes, determining the target clearance state of the air duct assembly according to the target operating modes of the first compartment and the second compartment.

[0123] The target clearance state of the air duct assembly is determined according to the target operating modes of the first chamber and the second chamber, including: when the target operating modes of the first chamber and the second chamber are both cooling mode or heating mode, the target clearance state of the air duct assembly is a first clearance state; when the target operating mode of the first chamber is cooling mode and the target operating mode of the second chamber is heating mode, the target clearance state of the air duct assembly is a second clearance state; when the target operating mode of the first chamber is heating mode and the target operating mode of the second chamber is cooling mode, the target clearance state of the air duct assembly is a third clearance state.

[0124] In this embodiment, the content and function of determining the target clearance state of the air duct assembly according to the target operating mode of the first chamber and the second chamber are consistent with those of determining the target clearance state of the air duct assembly according to the first comparison result, and are not further described here.

[0125] S114, the processor controls the air duct component according to the target clearance status.

[0126] Controlling the air duct assembly according to the target clearance state includes: determining the current clearance state of the air duct assembly according to the current operation mode of the first chamber and the second chamber; controlling each damper of the air duct assembly to maintain the current state when the current clearance state is the same as the target clearance state; closing the first steering damper and the second steering damper when the current clearance state is the first clearance state and the target clearance state is the second clearance state; closing the first damper and the second damper when the current clearance state is the first clearance state and the target clearance state is the third clearance state; and closing the first damper and the second damper when the current clearance state is the second clearance state and the target clearance state is the third clearance state. When the target clearance status is the third clearance status, the first damper and the second damper are closed, and the first steering damper and the second steering damper are opened; when the current clearance status is the second clearance status and the target clearance status is the first clearance status, the first steering damper and the second steering damper are opened; when the current clearance status is the third clearance status and the target clearance status is the first clearance status, the first damper and the second damper are opened; when the current clearance status is the third clearance status and the target clearance status is the second clearance status, the first damper and the second damper are opened, and the first steering damper and the second steering damper are closed.

[0127] The current clearance state of the air duct assembly is determined according to the current operating modes of the first chamber and the second chamber, including: when the current operating modes of the first chamber and the second chamber are both cooling mode or heating mode, the current clearance state of the air duct assembly is a first clearance state; when the current operating mode of the first chamber is cooling mode and the current operating mode of the second chamber is heating mode, the current clearance state of the air duct assembly is a second clearance state; when the current operating mode of the first chamber is heating mode and the current operating mode of the second chamber is cooling mode, the current clearance state of the air duct assembly is a third clearance state.

[0128] In this embodiment, the air duct assembly further includes a first damper, a second damper, a first turning damper, and a second turning damper. The first damper is disposed in the first air duct and located between the first compartment and the second compartment. The second damper is disposed in the second air duct and located between the first compartment and the second compartment. The first turning damper is disposed in the first air duct and located at the connection between the first air duct and the heating compartment. The second turning damper is disposed in the second air duct and located at the connection between the second air duct and the evaporator compartment. By disposing these dampers in corresponding positions in the air duct assembly, the air flow between the first air duct, the second air duct, the first compartment, the second compartment, the heating compartment, and the evaporator compartment is controlled. In this embodiment, the current clearance state of the air duct assembly is first determined based on the current operating mode of the first compartment and the second compartment. The current clearance state is then compared with a target clearance state, and the on / off state of each damper is controlled based on the comparison result.

[0129] Specifically, by comparing the current clearance state with the target clearance state, if the two are identical, there is no need to adjust the on / off states of the dampers; the dampers of the duct assembly can simply be controlled to maintain their current states. If switching from the first clearance state to the second clearance state, the first and second diverting dampers are closed, while the first and second dampers remain open, allowing cold air from the evaporator compartment to enter the first chamber through the first duct, while hot air from the heating compartment enters the second chamber through the second duct. If switching from the first clearance state to the third clearance state, the first and second dampers are closed, while the first and second diverting dampers remain open, preventing cold air from entering the first chamber and hot air from entering the second chamber. This allows hot air to circulate through the first duct, the second duct, the heating compartment, and the first chamber, improving the even distribution of hot air within the first chamber, while allowing cold air to circulate through the first duct, the second duct, the evaporator compartment, and the second chamber, improving the even distribution of cold air within the second chamber. If the switch is switched from the second clearance state to the third clearance state, the first and second dampers are closed, and the first and second diverting dampers are opened. If the switch is switched from the second clearance state to the first clearance state, the first and second diverting dampers are opened and maintained open, allowing cold or hot air to flow freely between the first and second air ducts, the first and second compartments, the heating chamber, and the evaporator compartment, achieving uniform cooling or heating. If the switch is switched from the third clearance state to the first clearance state, the first and second dampers are opened, and the first and second diverting dampers are maintained open. If the switch is switched from the third clearance state to the second clearance state, the first and second dampers are opened, and the first and second diverting dampers are closed. In this embodiment, by precisely controlling the open and close states of each damper, the refrigerator can precisely adjust the air flow direction to meet the temperature requirements of different compartments, thereby improving the refrigerator's energy efficiency, enhancing its flexibility, and enhancing the user experience.

[0130] The control method for a refrigerator provided by the embodiment of the present disclosure can respond to a user's mode switching request, obtain the target compartment and target operating mode corresponding to the mode switching request, and obtain the current operating mode of the first compartment and the second compartment. Then, based on the current operating mode and the target operating mode, the target clearance state of the air duct component is determined, and the air duct component is controlled so that the target compartment can operate in the target operating mode to meet the user's needs. Compared with the related art that can only realize the conversion of the cooling function and heating function of a single compartment, the present application can simultaneously control the air duct component so that the corresponding operating mode conversion between the first compartment and the second compartment is carried out according to the user's needs, thereby improving the diversity of the refrigerator function and improving the flexibility of the refrigerator. By allowing the user to flexibly adjust the operating mode of the refrigerator to meet the different temperature requirements of different compartments, the user's refrigerator usage experience is improved. By intelligently managing the clearance state of the air duct component, it is easy to ensure the efficient use of energy and the precise control of the compartment temperature.

[0131] Optionally, the method further includes: determining the on / off status of the compressor and the heating component according to the current operating mode and the target operating mode.

[0132] Furthermore, determining the on / off states of the compressor and the heating component based on the current operating mode and the target operating mode includes: when the target compartment is the first compartment and the target operating mode of the first compartment is different from the current operating mode, comparing the target operating mode of the first compartment with the current operating mode of the second compartment to obtain a first comparison result; and determining the on / off states of the compressor and the heating component based on the first comparison result.

[0133] In this embodiment, if the first comparison result shows that both the first and second chambers are operating in cooling mode, the heating component is turned off and the compressor is maintained on. If the first comparison result shows that both the first and second chambers are operating in heating mode, the compressor is turned off and the heating component is maintained on. If the first comparison result shows that the first chamber is operating in cooling mode and the second chamber is operating in heating mode, the compressor is turned on and the heating component is maintained on. If the first comparison result shows that the first chamber is operating in heating mode and the second chamber is operating in cooling mode, the heating component is turned on and the compressor is maintained on.

[0134] Furthermore, determining the on / off states of the compressor and the heating component based on the current operating mode and the target operating mode includes: when the target compartment is the second compartment and the target operating mode of the second compartment is different from the current operating mode, comparing the target operating mode of the second compartment with the current operating mode of the first compartment to obtain a second comparison result; and determining the on / off states of the compressor and the heating component based on the second comparison result.

[0135] The specific effects of this embodiment are described with reference to the above embodiment and will not be repeated here.

[0136] Furthermore, determining the on / off states of the compressor and the heating assembly according to the current operating mode and the target operating mode includes: when the target compartments are the first compartment and the second compartment, determining the on / off states of the compressor and the heating assembly according to the current operating modes of the first compartment and the second compartment and the target operating modes of the first compartment and the second compartment.

[0137] In this embodiment, when the current operating modes of the first and second chambers are both cooling modes, and when the current operating modes of the first and second chambers are both heating modes, the compressor is turned off and the heating component is turned on. When the current operating modes of the first and second chambers are both heating modes, and when the current operating modes of the first and second chambers are both cooling modes, the compressor is turned on and the heating component is turned off. When the current operating modes of the first and second chambers are both cooling modes and heating modes, and when the target operating modes of the first and second chambers are both cooling modes and heating modes, the compressor and the heating component are kept on.

[0138] Optionally, after controlling the air duct assembly, the method further includes: obtaining a first temperature difference ΔT1 between the first chamber and a second temperature difference ΔT2 between the second chamber; when both the first chamber and the second chamber operate in cooling mode and ΔT1>2ΔT2, or when both the first chamber and the second chamber operate in heating mode and In the case of , close the auxiliary damper; in the first room and the second room both run the cooling mode, and In the case of , or, in the case that both the first room and the second room are in heating mode and ΔT1>2ΔT2, close the first damper and the second damper; wherein ΔT1=T s1 -T1, ΔT2 = T s2 -T2, T s1 Indicates the set temperature of the first room, T1 indicates the current temperature of the first room, T s2 Indicates the set temperature of the second chamber, and T2 indicates the current temperature of the second chamber.

[0139] In this embodiment, the air duct assembly further includes an auxiliary air duct and an auxiliary damper. Opposite ends of the auxiliary air duct are respectively connected to the first and second compartments, the auxiliary air duct is located between the first and second compartments, and the auxiliary damper is disposed in the auxiliary air duct. In this embodiment, the auxiliary air duct and the auxiliary damper are combined with a first temperature difference ΔT1 between the first compartment and a second temperature difference ΔT2 between the second compartment, and the on / off state of the auxiliary damper is adjusted to facilitate synchronous temperature control of the first and second compartments, i.e., the first and second compartments reach the set temperature simultaneously, thereby improving the overall energy efficiency and temperature uniformity of the refrigerator.

[0140] Specifically, first calculate the first temperature difference ΔT1 between the set temperature and the current temperature of the first chamber, and the second temperature difference ΔT2 between the set temperature and the current temperature of the second chamber. Compare with 2ΔT2. When both the first and second rooms are running in cooling mode, and ΔT1>2ΔT2, it means that the second room is expected to reach the set temperature faster. At this time, close the auxiliary damper to reduce the exchange of cold air between the first and second rooms, realize the circulation of cold air in the first and second rooms, and speed up the cooling rate of the first room. When both the first and second rooms are running in heating mode, and In the case of , it means that the first room is expected to reach the set temperature faster. At this time, the auxiliary damper is closed to reduce the hot air exchange between the first room and the second room, so as to realize the circulation of hot air in the first room and the second room and speed up the heating rate of the second room. When both the first room and the second room are running in cooling mode, and If ΔT1 > 2ΔT2, it indicates that the first room is expected to reach the set temperature faster. In this case, the first and second dampers are closed to reduce the amount of cold air entering the first room and increase the amount of cold air entering the second room, thereby reducing the cooling rate of the first room and accelerating the cooling rate of the second room. If both the first and second rooms are operating in heating mode and ΔT1 > 2ΔT2, it indicates that the second room is expected to reach the set temperature faster. In this case, the first and second dampers are closed to reduce the amount of cold air entering the second room and increase the amount of cold air entering the first room, thereby reducing the heating rate of the second room and accelerating the heating rate of the first room.

[0141] Combine Figure 12 As shown, the embodiment of the present disclosure provides another control method for a refrigerator, comprising:

[0142] S121 : In response to a mode switching request, the processor obtains a target compartment and a target operating mode corresponding to the mode switching request.

[0143] S122: The processor obtains the current operating modes of the first chamber and the second chamber.

[0144] S123, the processor determines the target clearance state of the air duct component according to the current operation mode and the target operation mode.

[0145] S124, the processor controls the air duct component according to the target clearance status.

[0146] S125 , the processor obtains in real time a first temperature difference ΔT1 between the first chamber and a second temperature difference ΔT2 between the second chamber.

[0147] S126 , the processor calculates the actual temperature difference change rate ratio P between the first chamber and the second chamber = ΔT1 / ΔT2 .

[0148] S127: When P>P0, the processor closes the auxiliary damper.

[0149] S128: When P < P0, the processor opens the auxiliary damper.

[0150] Where P0 represents the ideal temperature difference between the first and second chambers, ΔT1 = T s1 -T1, ΔT2 = T s2 -T2, T s1 Indicates the set temperature of the first room, T1 indicates the current temperature of the first room, T s2 Indicates the set temperature of the second chamber, and T2 indicates the current temperature of the second chamber.

[0151] In this embodiment, both the first and second compartments operate in cooling mode. The air duct assembly further includes an auxiliary air duct and an auxiliary damper. The auxiliary air duct is connected to the first and second compartments at opposite ends, respectively. The auxiliary air duct is located between the first and second compartments, and the auxiliary damper is disposed in the auxiliary air duct. In this embodiment, the auxiliary air duct and the auxiliary damper are combined with the actual temperature difference change rate ratio P between the first and second compartments and the ideal temperature difference change rate ratio P0 between the first and second compartments to adjust the opening and closing state of the auxiliary damper to facilitate synchronous temperature control of the first and second compartments, i.e., the first and second compartments reach the set temperature simultaneously, thereby improving the overall energy efficiency and temperature uniformity of the refrigerator.

[0152] Specifically, the actual temperature difference change rate ratio P between the first and second compartments is calculated in real time. The ideal temperature difference change rate ratio P0 between the first and second compartments is determined by the initially obtained first temperature difference ΔT1 of the first compartment and the second temperature difference ΔT2 of the second compartment. By comparing P and P0, if P>P0, it indicates that the temperature of the first compartment is changing too quickly. In this case, the auxiliary damper is closed to slow down the temperature change rate of the first compartment. If P<P0, it indicates that the temperature of the second compartment is changing too quickly. In this case, the auxiliary damper is opened to quickly cool the first compartment.

[0153] Optionally, the method further includes: comparing the target operating mode of the target compartment with the current operating mode of the compartment corresponding to the target compartment; when the operating modes are different, replacing the initial startup temperature threshold of the target compartment with the first startup temperature threshold, and replacing the initial shutdown temperature threshold of the target compartment with the first shutdown temperature threshold, so that the target compartment operates according to the first startup temperature threshold and the first shutdown temperature threshold when operating the target operating mode; after the target compartment operates according to the first startup temperature threshold and the first shutdown temperature threshold for a preset period of time, replacing the first startup temperature threshold of the target compartment with the first shutdown temperature threshold. The target compartment temperature threshold is replaced with the initial start-up temperature threshold, and the first shutdown temperature threshold of the target compartment is replaced back to the initial shutdown temperature threshold, so that the target compartment operates according to the initial start-up temperature threshold and the initial shutdown temperature threshold when running the target operation mode; wherein, when the target operation mode is the cooling mode, the first start-up temperature threshold>the initial start-up temperature threshold, and the first shutdown temperature threshold>the initial shutdown temperature threshold; when the target operation mode is the heating mode, the first start-up temperature threshold<the initial start-up temperature threshold, and the first shutdown temperature threshold<the initial shutdown temperature threshold.

[0154] In this embodiment, when the current operating mode of the target compartment differs from the target operating mode, the start-up temperature threshold and the shutdown temperature threshold of the target compartment are replaced with the first start-up temperature threshold and the first shutdown temperature threshold, respectively. When the target operating mode is cooling mode, the first start-up temperature threshold is greater than the initial start-up temperature threshold, and the first shutdown temperature threshold is greater than the initial shutdown temperature threshold; when the target operating mode is heating mode, the first start-up temperature threshold is less than the initial start-up temperature threshold, and the first shutdown temperature threshold is less than the initial shutdown temperature threshold. By causing the target compartment to initially operate according to the first start-up temperature threshold and the first shutdown temperature threshold, the target compartment is prevented from being affected by cold air or hot air previously trapped in the target compartment during the initial stage of mode switching, thereby increasing the operating time or power of the compressor or heating component, thereby increasing the load on the compressor or heating component. By first making the target compartment operate according to the first startup temperature threshold and the first shutdown temperature threshold, and after running for a preset time, it is operated again according to the initial startup temperature threshold and the initial shutdown temperature threshold to meet user needs and provide buffer time to reduce the load of the compressor or heating component and increase the service life of the compressor or heating component.

[0155] Optionally, after controlling the air duct assembly, the method further includes: comparing current operating modes of the first chamber and the second chamber; if the operating modes are different, replacing the initial startup temperature threshold of the first chamber with the second startup temperature threshold, and replacing the initial shutdown temperature threshold of the first chamber with the second shutdown temperature threshold; replacing the initial startup temperature threshold of the second chamber with the third startup temperature threshold, and replacing the initial shutdown temperature threshold of the second chamber with the third shutdown temperature threshold.

[0156] Among them, when the current operating mode of the first chamber is cooling mode, the second startup temperature threshold is greater than the initial startup temperature threshold of the first chamber, and the second shutdown temperature threshold is greater than the initial shutdown temperature threshold of the first chamber; when the current operating mode of the first chamber is heating mode, the second startup temperature threshold is less than the initial startup temperature threshold of the first chamber, and the second shutdown temperature threshold is less than the initial shutdown temperature threshold of the first chamber; when the current operating mode of the second chamber is cooling mode, the third startup temperature threshold is greater than the initial startup temperature threshold of the second chamber, and the third shutdown temperature threshold is greater than the initial shutdown temperature threshold of the second chamber; when the current operating mode of the second chamber is heating mode, the third startup temperature threshold is less than the initial startup temperature threshold of the second chamber, and the third shutdown temperature threshold is less than the initial shutdown temperature threshold of the second chamber.

[0157] In this example, after controlling the air duct component, the target time has been set according to the target operating mode, and the mode switch is completed. At this time, by replacing the initial startup temperature threshold and the initial shutdown temperature threshold when the operating modes of the first and second compartments are different, the different operating modes of the first and second compartments can be used to avoid the mutual influence between the two compartments, which may lead to frequent startup of the compressor and heating component and increase the load on the compressor and heating component.

[0158] Optionally, the method further includes: closing the first vent and the second vent when the evaporator compartment temperature is less than a temperature threshold; obtaining the temperature change rate in the evaporator compartment; and increasing the heating efficiency of the heating component when the temperature change rate in the evaporator compartment is less than the temperature change rate threshold.

[0159] In this embodiment, the duct assembly connects to the heating chamber and the evaporator chamber at opposite ends, respectively. A first vent and a second vent are spaced apart along the duct assembly's extension. The first vent connects the first chamber to the duct assembly, while the second vent connects the second chamber to the duct assembly. By acquiring the evaporator chamber temperature, the ambient temperature of the evaporator can be monitored in real time. When the ambient temperature of the evaporator is too low, frost can easily form on the evaporator. If the evaporator chamber temperature falls below a threshold, the first and second vents are closed, the heating assembly is turned on, and the compressor is turned off. This directs hot air from the heating chamber into the evaporator chamber, defrosting the evaporator. Furthermore, if the rate of change of temperature within the evaporator chamber falls below the threshold, the heating efficiency of the heating assembly can be increased to improve the evaporator's defrosting efficiency, ensuring that the evaporator defrosts within a set timeframe. Increasing the heating efficiency of the heating assembly includes increasing the heating power of the heater and / or increasing the speed of the heating fan.

[0160] Combine Figure 13 As shown, the embodiment of the present disclosure provides another control method for a refrigerator, comprising:

[0161] S131 , in response to a mode switching request, the processor obtains a target compartment and a target operating mode corresponding to the mode switching request.

[0162] S132: The processor obtains the current operating modes of the first chamber and the second chamber.

[0163] S133, the processor determines the target clearance state of the air duct component according to the current operation mode and the target operation mode.

[0164] S134, the processor controls the air duct assembly according to the target clearance status.

[0165] S135: The processor obtains the weight change of the first chamber and the second chamber.

[0166] S136, when the weight change of the first compartment or the second compartment is greater than the weight change threshold, the processor closes the auxiliary damper; and replaces the power-on temperature threshold of the compartment whose weight change is greater than the weight change threshold with the load power-on temperature threshold, and replaces the power-off temperature threshold with the load power-off temperature threshold.

[0167] In this embodiment, when the compartment whose weight change is greater than the weight change threshold operates in cooling mode, the load startup temperature threshold is greater than the initial startup temperature threshold, and the load shutdown temperature threshold is greater than the initial shutdown temperature threshold; when the compartment whose weight change is greater than the weight change threshold operates in heating mode, the load startup temperature threshold is less than the initial startup temperature threshold, and the load shutdown temperature threshold is less than the initial shutdown temperature threshold. By obtaining the weight change of the first compartment and the second compartment, it is determined whether the first compartment and the second compartment are in a transfer state. If the weight change of the first compartment or the second compartment is greater than the weight change threshold, it means that the refrigerator door is open and the compartment whose weight change is greater than the weight change threshold is storing or accessing items. At this time, due to the opening of the refrigerator door and the replacement of items, a large amount of cold air or hot air will leak, and the demand for cold air or hot air will increase, causing the compressor or heating component to enter a high-load state. By replacing the startup temperature threshold of the compartment whose weight change is greater than the weight change threshold, that is, the compartment where items are being stored and retrieved, with the load startup temperature threshold, and replacing the shutdown temperature threshold with the load shutdown temperature threshold, the compressor or heating component is avoided from being frequently started up, thereby reducing the load of the compressor or heating component.

[0168] Optionally, the method further includes: obtaining the open / close state of the door; and increasing the rotation speeds of the heating fan and the condensing fan when the door is in the open state.

[0169] In this embodiment, by increasing the rotation speed of the heating fan and the condensing fan when the door is open, a stable cold air flow or hot air flow is formed on the side of the door, thereby reducing the cooling and / or heat loss of the first compartment and / or reducing the cooling and / or heat loss of the second compartment.
