[0068] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.

[0069] Figure 1 A structural schematic view of a refrigerator in the related art, Figure 2 An exploded view of Figure 1 Figure 3 ​​Fig. 1 is a structural schematic diagram of an inner container, a fan and an evaporator in a refrigerator in the related art, Figure 4 Fig. 2 is a structural schematic diagram of an evaporator and a heater in the related art,

[0070] Figure 5 Fig. 3 is a structural schematic diagram of the evaporator and the heater in another angle in the related art.

[0071] Referring to Figures 1 to 5 As shown in Fig. 1, in the related art, the frost-free refrigerator is also called the air-cooled refrigerator. The air-cooled refrigerator includes a cabinet 100, and the cabinet 100 includes an inner container 110 provided with an inner cavity. A duct cover plate 200 is arranged in the inner cavity to divide the inner cavity into a cold source chamber and a refrigeration chamber. The cold source chamber is provided with an evaporator 400, a heater 600 and a fan 500, etc. Under the action of the fan, air circulation is formed in the cold source chamber and the refrigeration chamber. The evaporator 400 has a relatively low temperature. The air enters from the bottom of the cold source chamber, exchanges cold energy with the evaporator 400, and the generated cold air is blown into the refrigeration chamber by the fan 500 to keep the temperature in the refrigeration chamber in a relatively low range. The evaporator 400 generates cold energy. After a period of refrigeration, frost formed by condensation of moisture in the air is deposited on the evaporator 400. At this time, the heater 600 (installed at the bottom of the evaporator 400) is needed to conduct heat from the bottom to the evaporator 400 to melt the frost on the evaporator 400 into water, which is then discharged to the outside of the refrigerator through the refrigerator drain pipe. However, the contact area between the heater and the evaporator is small, and the heat transfer efficiency is low. Therefore, the evaporator takes a long time to defrost, and the efficiency is low.

[0072] In order to overcome the defects in the related art, the refrigerator provided by the present application includes a cabinet, an evaporator, a heater and a heat conduction structure. The cabinet is provided with an inner cavity, the evaporator is located in the inner cavity, the heater is located in the inner cavity, the heater abuts against the evaporator, and the heat of the heater can be directly transferred to the evaporator to realize defrosting. The heat conduction structure is located in the inner cavity, the heat conduction structure abuts against the heater, the heat conduction structure abuts against the evaporator, and the orthogonal projection of the evaporator extending plane towards the heat conduction structure is located in the heat conduction structure. In this way, the heat of the heater can be transferred to the evaporator through the heat conduction structure, and the orthogonal projection of the evaporator extending plane towards the heat conduction structure is located in the heat conduction structure, that is, the area of the heat conduction structure is large, so that the heat transfer of the heater to each position of the evaporator can be accelerated, the defrosting time is reduced, and the defrosting efficiency is improved.

[0073] The content of the present application will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly and specifically understand the content of the present application.

[0074] Figure 6 Fig. 1 is a structural schematic diagram of an inner container, a fan and an evaporator in a refrigerator in the related art,

[0075] The application provides a refrigerator. The refrigerator can be a direct-cooling refrigerator or an air-cooled refrigerator. The application is described below by taking the air-cooled refrigerator as an example.

[0076] Referring to Figure 6 As shown in the figure, in some embodiments, the refrigerator comprises a cabinet 100.

[0077] The cabinet 100 is provided with an inner cavity.

[0078] In some embodiments, the cabinet 100 comprises an outer shell.

[0079] The outer shell is configured with a first containing cavity having a first access opening and a second access opening, and the first access opening and the second access opening are respectively arranged on opposite sides of the outer shell in the depth direction (the direction indicated by the Y axis) of the cabinet 100. The first access opening can be arranged on the front side of the outer shell, and the second access opening can be arranged on the rear side of the outer shell.

[0080] In some embodiments, the cabinet 100 comprises a compressor compartment. The compressor compartment is located in the outer shell, and the opening of the compressor compartment is opposite to the second access opening. The compressor and the condenser can be placed in the compressor compartment through the second access opening and the opening.

[0081] In some embodiments, the cabinet 100 comprises an inner container 110.

[0082] The inner container 110 is located in the outer shell, and the inner container 110 is formed with at least one refrigeration compartment. The inner container 110 has a third access opening, and the third access opening is opposite to the first access opening. The third access opening and the first access opening are used to place articles in the refrigeration compartment.

[0083] The inner container 110, the outer shell and the compressor compartment are filled with a foaming layer. The foaming layer is used to insulate and heat the refrigeration compartment, so as to ensure the refrigeration effect in the refrigeration compartment.

[0084] In some embodiments, the refrigerator further comprises an air duct cover plate 200. The inner container 110 is provided with an inner cavity, and the air duct cover plate 200 is located in the inner cavity to divide the inner cavity into a refrigeration compartment and a cold source chamber along the depth direction. The depth direction is the direction indicated by the Y axis.

[0085] The cold source chamber and the refrigeration compartment are in communication with each other. When the fan 500 is working, the air in the cold source chamber and the refrigeration compartment circulates and flows. The refrigeration compartment can be any one of a refrigeration compartment, a freezing compartment or a variable-temperature compartment.

[0086] Referring to Figure 6 As shown in the figure, in some embodiments, the refrigerator comprises a door body 300.

[0087] The door body 300 is movably connected with the box body 100, and the door body 300 is arranged on the front side of the box body 100 to be opened and closed, so as to close and open the cold source chamber.

[0088] Figure 7 A structure schematic diagram of a refrigeration system in a refrigerator is provided in the embodiments of the present application.

[0089] Referring to Figure 7 In some embodiments, the refrigerator includes a refrigeration system.

[0090] The refrigeration system can include a compressor 700, a condenser 800, a throttling device 900, and an evaporator 400. The compressor 700, the condenser 800, the throttling device 900, and the evaporator 400 are sequentially connected by a pipeline, and a refrigerant flows through the pipeline. The compressor 700 and the condenser 800 can be arranged in a compressor chamber, and the evaporator 400 is arranged in a cold source chamber.

[0091] When the compressor 700 is working, low-temperature and low-pressure refrigerant is sucked into the compressor 700, compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor 700, and then discharged into the condenser 800. The high-temperature and high-pressure refrigerant gas is cooled by the condenser 800, and the temperature continuously decreases, gradually cooled into normal-temperature and high-pressure saturated steam, and further cooled into saturated liquid. The pressure of the refrigerant hardly changes during the entire condensation process. The throttling device 900 can include a pressure-reducing pipe or an electronic expansion valve. In the present application, the throttling device is described by taking the pressure-reducing pipe as an example. The pressure-reducing pipe has low cost and is not prone to abnormal failure. The saturated liquid refrigerant after condensation is throttled and depressurized by the pressure-reducing pipe, and the refrigerant becomes normal-temperature and low-pressure wet steam. Then, the normal-temperature and low-pressure wet steam absorbs heat and vaporizes through the evaporator 400, not only reducing the temperature of the evaporator 400 and its surrounding, but also changing the refrigerant into low-temperature and low-pressure gas. The evaporator 400 cools the air in the cold source chamber, so that the temperature of the air in the cold source chamber is reduced. Under the action of the fan, the cold air in the cold source chamber flows to the refrigeration chamber through the air duct cover plate 200, so that the temperature of the refrigeration chamber is reduced. The refrigerant from the evaporator 400 returns to the compressor 700 again, and the above process is repeated, so that the evaporator 400 can continuously cool the air in the cold source chamber, and the refrigeration chamber can be maintained at a set temperature.

Figure 10 A structure schematic diagram of a fan in a refrigerator is provided in the embodiments of the present application.

[0093] Referring to Figures 8 to 10 As shown in FIG. 1, in some embodiments, the refrigerator comprises a fan 500.

[0094] The fan 500 is located in the cold source chamber.

[0095] The fan 500 is provided with an air inlet structure 510, which is in communication with the cold source chamber. When the fan 500 is running, the air in the cold source chamber enters the fan 500 through the air inlet structure 510, and then is discharged into the refrigeration compartment by the fan 500.

[0096] Specifically, the air inlet structure 510 can be circular.

[0097] The evaporator 400 is located in the cold source chamber and is located on one side of the fan 500.

[0098] Specifically, referring to Figure 9 As shown in FIG. 1, the evaporator 400 is located in the cold source chamber and is located below the fan 500. Under the action of the fan 500, the air flows from the bottom of the evaporator 400 towards the air inlet structure 510.

[0099] Figure 11 The structure diagram of the evaporator and the heater in the refrigerator provided by the embodiments of the present application is shown in Figure 12 is a top view. Figure 11

[0100] Referring to Figure 11 and Figure 12 As shown in FIG. 1, in some embodiments, the refrigerator comprises a heater 600. When the heater 600 is running, the heat generated by the heater 600 is transferred to the evaporator 400, so that the frost on the evaporator 400 can be melted.

[0101] The heater 600 is located in the inner cavity, specifically, the heater 600 is located in the cold source chamber.

[0102] Specifically, the heater 600 is located on one side of the evaporator 400. The heater 600 abuts against the evaporator 400, so that the heat can be directly transferred to the evaporator 400.

[0103] Specifically, the heater 600 can be located on the side of the evaporator 400 away from the fan 500.

[0104] Specifically, the heater 600 is located at the bottom of the evaporator 400.

[0105] Referring to Figure 11 and Figure 12 As shown in FIG. 1, in some embodiments, the evaporator 400 comprises a body 410.

[0106] In some embodiments, the body 410 comprises a refrigeration pipeline 411. The refrigeration pipeline 411 is used for the flow of refrigerant.​

[0107] In some embodiments, the refrigeration pipe 411 is arranged in a serpentine shape.

[0108] In some embodiments, the body 410 comprises a support 412. The support 412 is used to support the refrigeration pipe 411.

[0109] The refrigeration pipe 411 is inserted on the support 412.

[0110] The number of supports 412 is at least two, and the at least two supports 412 are arranged in a first direction.

[0111] Specifically, the number of supports 412 is two.

[0112] It should be noted that the first direction is the width direction of the cabinet 100, that is, the direction indicated by the X axis in the figure.

[0113] In some embodiments, the body 410 comprises a temperature controller, and the temperature controller is arranged on the refrigeration pipe 411.

[0114] Referring to FIGS. 1 and 2, Figure 10 and Figure 11 In some embodiments, the evaporator 400 comprises a plurality of fins 420.

[0115] The fins 420 are arranged on the outer wall of the body 410.

[0116] Specifically, the fins 420 are arranged on the outer wall of the refrigeration pipe 411.

[0117] In some embodiments, the heater 600 is inserted on the support 412. The heat generated by the heater 600 can be transmitted to the refrigeration pipe 411 through the support 412, and then transmitted to the fins 420 through the refrigeration pipe 411.

[0118] Figure 13 The schematic view of the evaporator, the heater and the heat conduction structure in the refrigerator provided by the embodiments of the present application, Figure 14 the exploded view of Figure 13 , and Figure 15 The structural schematic view of the heat conduction structure in the refrigerator provided by the embodiments of the present application.

[0119] Referring to FIGS. 1 and 2, Figure 8 , Figures 13 to 15 In some embodiments, the refrigerator comprises a heat conduction structure 1000. The heat conduction structure 1000 is used to transmit the heat of the heater 600 to the evaporator, so as to melt the frost on the fins 420 of the evaporator.

[0120] The heat conduction structure 1000 is located in the inner cavity. Specifically, the heat conduction structure 1000 is located in the cold source chamber.

[0121] The heat-conducting structure 1000 abuts against the heater 600 and the evaporator 400. The heat from the heater 600 can be transferred to the evaporator 400 through the heat-conducting structure 1000.

[0122] In some embodiments, the orthographic projection of the evaporator 400 toward the plane extending from the heat-conducting structure 1000 is located within the heat-conducting structure 1000. This results in a larger area of ​​the heat-conducting structure 1000 and a larger contact area between the heat-conducting structure 1000 and the evaporator 400. This allows for faster and more uniform heat transfer from the heat-conducting structure 1000 to the evaporator 400, thereby accelerating the heat transfer from the heater 600 to all parts of the evaporator 400, reducing defrosting time, and improving defrosting efficiency.

[0123] It should be noted that the extension plane of the heat-conducting structure 1000 is the plane shown by the Z-axis and X-axis in the figure. The orthographic projection of the evaporator 400 toward the extension plane of the heat-conducting structure 1000 can coincide with the orthographic projection of the heat-conducting structure 1000, or the orthographic projection of the evaporator 400 toward the extension plane of the heat-conducting structure 1000 can be smaller than the orthographic projection of the heat-conducting structure 1000.

[0124] Understandably, when the fan 500 is located above the evaporator 400, the frost on the evaporator 400 is mainly concentrated at the bottom. By placing the heater 600 at the bottom of the evaporator 400 and the heat conduction structure 1000 transferring heat from the bottom upwards, which is consistent with the frost thickness, the defrosting speed can be accelerated.

[0125] See Figures 13 to 15 As shown, in some embodiments, the thermally conductive structure 1000 includes a first thermally conductive portion 1010.

[0126] In this design, the extending plane of the first heat-conducting part 1010 is parallel to the extending plane of the evaporator 400, and the first heat-conducting part 1010 abuts against the outer wall of the evaporator 400. The orthographic projection of the evaporator 400 toward the extending plane of the first heat-conducting part 1010 is located within the first heat-conducting part 1010. This results in a larger area for the first heat-conducting part 1010 and a larger contact area with the evaporator 400, thereby accelerating the transfer of heat from the heater 600 to all parts of the evaporator 400, reducing defrosting time, and improving defrosting efficiency.

[0127] It should be noted that the extension plane of the first heat-conducting part 1010 is the plane shown by the Z-axis and X-axis in the figure. The extension plane of the evaporator 400 is also the plane shown by the Z-axis and X-axis in the figure. The orthographic projection of the evaporator 400 toward the extension plane of the first heat-conducting part 1010 can coincide with the orthographic projection of the first heat-conducting part 1010, or the orthographic projection of the evaporator 400 toward the extension plane of the first heat-conducting part 1010 can be smaller than the orthographic projection of the first heat-conducting part 1010.

[0128] Exemplarily, the first heat-conducting part 1010 can be in a plate shape.

[0129] In some embodiments, the heat-conducting structure 1000 comprises a second heat-conducting part 1020.

[0130] The second heat-conducting part 1020 is connected to the bottom of the first heat-conducting part 1010, and the second heat-conducting part 1020 abuts against the outer wall of the heater 600. The heat generated by the heater 600 can be transmitted to the first heat-conducting part 1010 through the second heat-conducting part 1020. By arranging the second heat-conducting part 1020, the contact area between the heat-conducting structure 1000 and the heater 600 is increased, and the heat transmission efficiency is improved.

[0131] Exemplarily, the second heat-conducting part 1020 can be in a plate shape.

[0132] Referring to Figures 13 to 15 In some embodiments, the heat-conducting structure 1000 further comprises a third heat-conducting part 1030.

[0133] The extension plane of the third heat-conducting part 1030 is parallel to the extension plane of the evaporator 400. The third heat-conducting part 1030 is located on the side of the evaporator 400 away from the first heat-conducting part 1010. The third heat-conducting part 1030 abuts against the outer wall of the evaporator 400. The bottom of the third heat-conducting part 1030 is connected to the second heat-conducting part 1020.

[0134] It should be noted that the extension plane of the third heat-conducting part 1030 is the plane shown by the Z axis and the X axis in the figure. The extension plane of the evaporator 400 is the plane shown by the Z axis and the X axis in the figure.

[0135] It can be understood that, by arranging the third heat-conducting part 1030, the third heat-conducting part 1030 and the first heat-conducting part 1010 are located on opposite sides of the evaporator 400.

[0136] In some embodiments, the normal projection of the evaporator 400 towards the extension plane of the third heat-conducting part 1030 is located in the third heat-conducting part 1030. In this way, the area of the third heat-conducting part 1030 is large, and the contact area between the third heat-conducting part 1030 and the evaporator 400 is large. Therefore, the heat transmission of the heater 600 to each position of the evaporator 400 is accelerated, the defrosting time is reduced, and the defrosting efficiency is improved.
