[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0047] In some embodiments, in combination Figures 1 to 4 As shown, a refrigerator 1 is provided, comprising a housing 10, a heating assembly 20, an evaporator 30 and an air duct assembly 40. The housing 10 comprises a first chamber 120, a second chamber 130, a heating chamber 110 and an evaporator chamber 140. The heating assembly 20 is arranged in the heating chamber 110. The evaporator 30 is arranged in the evaporator chamber 140. The air duct assembly 40 comprises a main air duct 410 and a main air door 420, and opposite ends of the main air duct 410 are respectively connected to the heating chamber 110 and the evaporator chamber 140. Along the extension direction of the main air duct 410, the main air duct 410 is provided with a first vent 412 and a second vent 414 at intervals, the first vent 412 is used to connect the first chamber 120 and the main air duct 410, and the second vent 414 is used to connect the second chamber 130 and the main air duct 410. The main air door 420 is disposed in the main air duct 410 and is located between the first ventilation opening 412 and the second ventilation opening 414 .

[0048] The box body 10 of the refrigerator 1 provided in the embodiment of the present disclosure includes two storage compartments, a first compartment 120 and a second compartment 130, which increases the number of storage compartments compared with the related art, and improves the storage flexibility and storage space utilization of the refrigerator 1. At the same time, a heater 210 is provided in the heating cabin 110 for generating hot air; and an evaporator 30 is provided in the evaporator cabin 140 for generating cold air. In addition, by providing a main air duct 410 connected to the heating cabin 110 and the evaporator cabin 140, and the main air duct 410 includes a first vent 412 for connecting the first compartment 120 and a second vent 414 for connecting the second compartment 130, so as to guide the cold air or hot air to the first compartment 120 and / or the second compartment 130. And a main air door 420 is provided between the first vent 412 and the second vent 414, and the main air duct 410 is controlled to achieve different conduction states to control the flow direction of the cold air and / or hot air to achieve different working modes.

[0049] Specific, combined Figure 1 As shown in the figure (the arrow 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 2As shown in the figure (the arrow 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 3 As shown (the arrow in the figure indicates the direction of air flow), when the main air door 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 component 20 and the evaporator 30 are turned on to generate hot air and cold air respectively. Among them, the cold air passes through the main air duct 410 through the first vent 412 to enter the first chamber 120, and the hot air passes through the main air duct 410 through the second vent 414 to enter the second chamber 130, so that the refrigerator 1 can achieve cooling and heating at the same time.

[0050] Compared with the related art, the refrigerator 1 of the present application can realize simultaneous cooling and heating on the basis of realizing uniform cooling or uniform heating, thereby improving the diversity of functions and flexibility of use of the refrigerator 1, so that the refrigerator 1 can maintain ideal storage conditions under different ambient temperatures, and improve its scope of application. It also improves the user experience.

[0051] Optionally, combined Figures 1 to 4 As shown, the box body 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.

[0052] In this embodiment, the compressor 60 is disposed in the compressor compartment 170, and the compressor 60 is connected to the evaporator 30 so as to provide the evaporator 30 with a refrigerant in a low-temperature and low-pressure state. The liquid refrigerant in the evaporator 30 evaporates rapidly to absorb heat, and the air passing through the evaporator 30 is cooled and becomes cold air, thereby generating cold air. Therefore, by controlling the start and stop of the compressor 60, the working state of the evaporator 30 can be controlled, thereby controlling the generation and stop of cold air.

[0053] It should be noted that turning on the evaporator 30 in the present application actually means turning on the compressor 60 to provide the evaporator 30 with a low-temperature, low-pressure refrigerant, so that the air passing through the evaporator 30 is cooled and becomes cold air. Turning off the evaporator 30 in the present application actually means turning off the compressor 60 to stop providing the evaporator 30 with a low-temperature, low-pressure refrigerant, so that the temperature of the air passing through the evaporator 30 remains unchanged.

[0054] Optionally, combined Figures 1 to 4As shown, along the height direction of the cabinet 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.

[0055] In this embodiment, along the height direction of the refrigerator 1, the first chamber 120 is located above the second chamber 130, and the heating chamber 110 is arranged above the first chamber 120. By limiting the positions of the heating chamber 110 and the evaporator chamber 140 to opposite ends of the box body 10, the heating chamber 110 and the evaporator chamber 140 are prevented from being too close to each other, and the hot air generated in the heating chamber 110 and the cold air generated in the evaporator chamber 140 exchange heat and offset each other.

[0056] Optionally, combined Figure 5 and Figure 6 As shown, the air duct assembly 40 further includes an auxiliary air duct 430 and an auxiliary air door 440. The opposite ends of the auxiliary air duct 430 are respectively connected to the first chamber 120 and the second chamber 130, and the main air duct 410 and the auxiliary air duct 430 are arranged in the box body 10 at intervals. The auxiliary air door 440 is arranged in the auxiliary air duct 430.

[0057] In this embodiment, the two opposite ends of the auxiliary air duct 430 are connected to the first chamber 120 and the second chamber 130 respectively, and 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 to provide an additional air circulation path and balance the temperature between the two chambers. By providing an auxiliary air door 440 in the auxiliary air duct 430 to control the air flow in the auxiliary air duct 430, the temperature of the refrigerator 1 is adjusted in coordination with the main air duct 410 and the auxiliary air door 440.

[0058] 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 5As 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 5 As shown, when the first chamber 120 is heated and the second chamber 130 is cooled, the main air door 420 and the auxiliary air door 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 conduction between the first chamber 120 and the second chamber 130 to ensure the temperature stability of the first chamber 120 and / or the second chamber 130.

[0059] Optionally, combined Figure 5 and Figure 6 As shown, there are two main air ducts 410, which are symmetrically arranged on the box body 10. There are two main air doors 420, which are arranged one by one with the two main air ducts 410. The auxiliary air duct 430 is located between the two main air ducts 410.

[0060] In this embodiment, the symmetrical layout of the two main air ducts 410 allows 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 the airflow. The auxiliary air duct 430 is located between the two main air ducts 410, and plays a role in supplementing and guiding the airflow, so as to further optimize the air circulation, ensure that the cold air or hot air can fully cover the entire interior of the refrigerator 1, and help to improve the cooling or heating effect, so that the refrigerator 1 performs better in different working modes.

[0061] Optionally, combined Figures 1 to 5 As shown, there are multiple first vents 412, which are evenly spaced and distributed in the main air duct 410 along the extension direction of the main air duct 410, and 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 in the main air duct 410 along the extension direction of the main air duct 410, and the multiple second vents 414 are used to connect the second chamber 130 and the main air duct 410.

[0062] 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 evenly distributed to each corner of the refrigerator 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 refrigerator 1.

[0063] Optionally, combined Figure 5 and Figure 6 As 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 disposed at the connection between one of the two main air ducts 410 and the heating chamber 110, and the second turning damper 460 is disposed at the connection between the other of the two main air ducts 410 and the evaporator chamber 140.

[0064] Combination Figure 6 As shown, in order to conveniently distinguish the two main air ducts 410, the following embodiment names the two main air ducts 410 as the first air duct 416 and the second air duct 418, respectively. The two main air doors 420 are named as the first air door 426 and the second air door 428, respectively. The first air door 426 is arranged in the first air duct 416 and is located between the first compartment 120 and the second compartment 130, and the second air door 428 is arranged in the second air duct 418 and is located between the first compartment 120 and the second compartment 130. Among them, the first turning air door 450 is arranged at the connection between the first air duct 416 and the heating compartment 110, and the second turning air door 460 is arranged at the connection between the second air duct 418 and the evaporator compartment 140.

[0065] It can be understood that the air duct assembly 40 includes a first air duct 416, a second air duct 418, a first air door 426, a second air door 428, a first turning air door 450 and a second turning air door 460. The first air duct 416 and the second air duct 418 are arranged at intervals, and the first air duct 416 and the second air duct 418 are arranged symmetrically. The first air duct 416 connects the first chamber 120, the second chamber 130, the heating chamber 110 and the evaporator chamber 140, and the second air duct 418 connects the first chamber 120, the second chamber 130, the heating chamber 110 and the evaporator chamber 140. The first air door 426 is arranged in the first air duct 416 and is located between the first chamber 120 and the second chamber 130, and the second air door 428 is arranged in the second air duct 418 and is located between the first chamber 120 and the second chamber 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 .

[0066] In this embodiment, the first turning damper 450 and the second turning damper 460 are added to control the connection state between the first air duct 416 and the heating chamber 110, and the connection state between the second air duct 418 and the evaporator chamber 140, so that the first air duct 416 and the second air duct 418 are used as a cooling air duct or a heating air duct respectively. Specifically, the first turning damper 450 and the second turning damper 460 are closed, and the first air duct 416 is connected to the first chamber 120, the second chamber 130 and the evaporator chamber 140, so that the first air duct 416 is used as a cooling air duct. At the same time, the second air duct 418 is connected to the heating chamber 110, the first chamber 120 and the second chamber 130, so that the second air duct 418 is used as a heating air 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 and increasing the energy consumption of the refrigerator 1 during the conversion process of the cooling or heating function.

[0067] 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 arranged at the first vent 412 and / or the second vent 414. Along the extension direction of the main air duct 410, the plane where the air guide plate 470 is located is inclined toward the direction where the evaporator compartment 140 is located.

[0068] In this embodiment, the wind guide plate 470 is tilted so that the plane where the wind guide plate 470 is located is tilted toward the direction where the evaporator compartment 140 is located, so as to guide the hot air flow toward the evaporator compartment 140. Specifically, when the refrigerator 1 is running the defrosting function, the wind guide plate 470 is tilted to optimize the transfer path of the hot air, so that the hot air flow is more concentrated to flow to the evaporator compartment 140, and the evaporator 30 is defrosted, thereby improving the defrosting efficiency of the refrigerator 1. At the same time, since the wind guide plate 470 is arranged at the first vent 412 and / or the second vent 414, it plays a role in guiding the flow, and the cold air flow flowing out of the evaporator compartment 140 can enter the first chamber 120 and / or the second chamber 130 more smoothly, so as to improve the refrigeration efficiency of the refrigerator 1. In addition, by tilting the air guide plate 470, it helps to reduce the turbulence and resistance of the air flow, allowing the air flow to flow more stably through the first vent 412 and / or the second vent 414, and the main air duct 410, thereby preventing the confusion and blockage of the air flow and ensuring the circulation of air inside the refrigerator 1.

[0069] 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 is located is θ, wherein 30°≤θ≤60°.

[0070] 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 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 is located to θ 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 the hot air flow, but also ensure the relatively stable 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.

[0071] Exemplarily, 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 is located is 30°, 40°, 45°, 50° or 60°.

[0072] Optionally, the air guide plate 470 includes a rubber air guide plate 470 or a silicone air guide plate 470 .

[0073] 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 used 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 Fig. 9 As shown, since the air guide plate 470 is disposed at the first vent 412 and / or the second vent 414, and the plane where the air guide plate 470 is located is inclined toward the direction where the evaporator compartment 140 is located, when the refrigerator 1 performs evaporator defrosting, the hot air flow 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 guide plate 470 or the silica gel air guide plate 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 directly enters the evaporator chamber 140 through the main air duct 410, avoiding the hot air flow from passing through the first vent 412 and / or the second vent 414 into the first chamber 120 and / or the second chamber 130, effectively preventing air flow leakage and energy loss, thereby improving the defrosting efficiency of the refrigerator 1.

[0074] 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 used 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 used to make the air guide plate 470 adapt to humid or corrosive environments and not 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 airflow 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.

[0075] 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 arranged at intervals at the first ventilation opening 412 and / or the second ventilation opening 414 .

[0076] 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 enhanced, thereby improving the defrosting or refrigeration efficiency of the refrigerator 1.

[0077] Optionally, combined Figures 1 to 8 As shown (the direction indicated by the arrow in the figure is the direction of air flow), the refrigerator 1 also includes a door body 50. The door body 50 is rotatably arranged on the box body 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, and the guide air door 490 is arranged at one end of the guide air duct 480 connected to the first chamber 120.

The guide air door 490 is arranged at one end of the guide air duct 480 connected to the first chamber 120. By controlling the switch state of the guide air door 490, the distribution of cold air or hot air in the first chamber 120 can be adjusted to achieve more accurate temperature regulation, and the dew removal function of the refrigerator 1 can be turned on or off.

[0079] Optionally, combined Figure 7 and Figure 8 As shown, along the height direction of the box body 10, the guide air duct 480 is spaced apart at one end close to the door body 50 with a front air port 482 and a rear air port 484. Along the depth direction of the box body 10, the distance from the front air port 482 to the door body 50 is smaller than the distance from the rear air port 484 to the door body 50. There are two guide air doors 490, which are respectively spaced apart at the front air port 482 and the rear air port 484.

[0080] In this embodiment, a front air port 482 and a rear air port 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 port 482 to the door body 50 is smaller than the distance from the rear air port 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 the front air outlet 482 and the rear air outlet 484, the flow direction of the airflow can be accurately controlled to meet 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 vent 484 is opened and the front air vent 482 is 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 vent 484, so as to quickly heat or cool the first chamber 120.

[0081] Optionally, combined Figure 3 , Figure 4 and Fig.10As shown, the guide air door 490 includes a swing blade mechanism 492.

Figure 3 and Fig.10 As shown in the figure (the direction indicated by the arrow in the figure is 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 through the swing blade mechanism 492 is inclined toward the bottom direction 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. Figure 4 and Fig.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 air flow direction 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 under the action of the top of the box 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.

By controlling the operation of the rotary motor 422, the angle of the guide vane 424 can be adjusted, thereby changing the ventilation state of the main air duct 410, thereby meeting different functional requirements of the refrigerator 1.

[0087] 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.

Then, in conjunction with the first turning damper 450 and the second turning damper 460, the refrigerator 1 realizes a working mode in which the first compartment 120 is cooled and the second compartment 130 is heated. Exemplarily, along the height direction of the box body 10, the heating compartment 110, the first compartment 120, the second compartment 130 and the evaporator compartment 140 are sequentially arranged from top to bottom.

When the refrigerator 1 is cooling the first chamber 120 and heating the second chamber 130, the first turning damper 450 and the second turning damper 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 is connected to the first chamber 120 and the evaporator chamber 140, and then the cold air in the evaporator chamber 140 enters the first chamber 120 through the first air duct 416 and the first vent 412, so that the first chamber 120 is cooled. 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 is connected to the second chamber 130 and the heating chamber 110, and then the hot air in the heating chamber 110 enters the second chamber 130 through the second air duct 418 and the second vent 414, so that the second chamber 130 is heated.

[0090] Compared with the related art, the refrigerator 1 of the present application can realize cooling of the first chamber 120 and heating of the second chamber 130, as well as heating of the first chamber 120 and cooling of the second chamber 130, on the basis of realizing uniform cooling or uniform heating, further improving the diversity of functions and flexibility of use of the refrigerator 1, so that the refrigerator 1 can maintain ideal storage conditions under different ambient temperatures, further improving the scope of application of the refrigerator 1. Improve the user experience.

[0091] Optionally, combined Figures 1 to 4 As shown, the evaporator compartment 140 is provided with an air supply port 142, and the air supply port 142 is used to connect the second chamber 130 and the evaporator compartment 140. A third air door 510 is provided at the air supply port 142.

[0094] Furthermore, combined with Fig. 9 As shown, by providing the third air door 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 , so as to prevent 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 .

[0095] 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.

In addition, by increasing the rotation speed of the heating fan 220, the air flow rate is increased, thereby improving the dew removal efficiency of the door body 50. For example, during the process of evaporator defrosting of the freezer 1, the heating fan 220 rotates in the opposite direction, so that the air in the heating chamber 110 flows along the extension direction of the guide air duct 480 toward the side away from the door body 50, so as to guide the air to the main air duct 410, and then reach the evaporator chamber 140, so as to achieve evaporator defrosting. In addition, by increasing the rotation speed of the heating fan 220, the air flow rate is increased, thereby improving the evaporator defrosting efficiency.

[0097] It should be noted that the specific positional relationship between the heater 210 and the heating fan 220, and the specific location 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.

The sealing gasket 160 is disposed at one end of the middle partition 150 close to the door body 50, and the sealing gasket 160 is used to seal the gap between the middle partition 150 and the door body 50.

[0103] In this embodiment, the middle partition 150 is used to cooperate with the box body 10 to define the first chamber 120 and the second chamber 130, and a sealing gasket 160 is provided at one end of the middle partition 150 close to the door body 50 to seal the gap between the middle partition 150 and the door body 50, so as to avoid the first chamber 120 and the second chamber 130 from exchanging heat through the gap between the middle partition 150 and the door body 50, thereby causing energy consumption.
