The ice hopper is located at the bottom of the ice-making assembly and is connected to the ice-making assembly. The bottom of the ice hopper is connected to the mounting box. The ice door structure is located in the mounting box and is connected to the mounting box. The ice door structure rotates relative to the mounting box to open or close the ice outlet of the ice hopper. The water receiving box is connected to the mounting box, the water receiving box is embedded in the front side of the door body, and the water receiving box is connected to the mounting box. Among them, the ice door structure includes an ice door box, a heat insulating member, a sealing member and a heating film. The heat insulating member is located in the area enclosed by the sealing member and the ice door box, and the heating film is arranged on the inner wall of the ice door box facing the heat insulating member.

[0004] However, the cost of heating the film is high and the energy consumption of the ice-discharging assembly is high. Summary of the invention

[0005] The present application provides a refrigerator with a low-cost ice-dispensing component and low energy consumption.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] The present application provides a refrigerator, comprising:

[0008] A box body, wherein the box body is provided with a refrigeration compartment;

[0009] The door body is rotatably connected to the cabinet to open or close the refrigeration compartment;

[0010] Ice making system, the ice making system includes:

[0011] An ice-making assembly, which is arranged in the refrigeration room or on the door;

[0012] The ice discharging assembly is arranged on the door body and includes:

[0013] An ice hopper, the ice hopper is connected to the ice making assembly, and the ice hopper is provided with a first ice outlet;

[0014] An installation box, the installation box is connected to the ice hopper, the first ice outlet is located at one end of the ice hopper facing the installation box, the installation box is provided with a first inner cavity and a second ice outlet communicated with the first inner cavity, the second ice outlet is opposite to and communicated with the first ice outlet;

[0015] An ice door structure, the ice door structure is located in the second inner cavity, the ice door structure is rotatably connected to the mounting box, and the ice door structure rotates relative to the mounting box to open or close the second ice outlet; when the ice door structure opens the second ice outlet, ice cubes in the ice making assembly enter the first inner cavity through the ice hopper, the first ice outlet, and the second ice outlet;

[0016] A heating wire is arranged on the installation box, and the second ice outlet is located in the area surrounded by the heating wire.

[0017] In this way, the heating wire is used instead of the heating film to reduce the cost. The heating wire is arranged on the installation box, the second ice outlet is located in the area surrounded by the heating wire, the heating wire is wound around the second ice outlet, and the heating wire is close to the cold source position where condensation is generated by heat transfer, thereby improving the effect of heat transfer, reducing energy consumption, and helping to reduce the thickness of the ice door structure.

[0018] In some embodiments, the heating wire is disposed on the inner wall of the mounting box.

[0019] In this way, the heating wire is closer to the ice gate structure, which is beneficial for transferring heat to the outer surface of the ice gate structure.

[0020] In some embodiments, an inner wall of the installation box is provided with a receiving portion, the second ice outlet is located in the area surrounded by the receiving portion, the receiving portion is provided with an opening on one side facing the ice door structure, and the heating wire is at least partially provided in the receiving portion;

[0021] When the ice door structure closes the second ice outlet, the ice door structure abuts against the heating wire.

[0022] This helps transfer heat to the outer surface of the ice door structure and reduces condensation.

[0023] In some embodiments, part of the heating wire is located outside the receiving portion through the opening of the receiving portion.

[0024] In this way, the contact area between the ice gate structure and the heating wire is larger, which is conducive to transferring heat to the outer surface of the ice gate structure.

[0025] In some embodiments, the orthographic projection of the heating wire toward the plane where the first end surface of the ice bucket is located is at least partially located within the first end surface of the ice bucket;

[0026] The first end surface is the end surface of the ice bucket facing the installation box.

[0027] The cold of the ice bucket is transferred to the ice bucket through the first end face. The larger the area of ​​the orthographic projection of the heating wire toward the plane where the first end face is located within the first end face, the more conducive it is to offset the cold of the ice bucket, improve the effect of heat transfer, and reduce energy consumption.

[0028] In some embodiments, the heating wire is provided in a single turn.

[0029] In this way, the cost of the heating wire is lower.

[0030] In some embodiments, the heating wire is a nickel-chromium alloy wire.

[0031] In this way, since the nickel-chromium alloy wire has a large resistance value, high power and high heat generation, the heating time can be shortened and the power consumption can be reduced.

[0033] The ice door structure is located in the second inner cavity, the ice door structure is rotatably connected to the mounting box, and the ice door structure rotates relative to the mounting box to open or close the second ice outlet; when the ice door structure opens the second ice outlet, ice cubes in the ice making assembly move to the outside of the ice outlet through the ice hopper, the first ice outlet, the second ice outlet, the fourth ice outlet, the second inner cavity and the third ice outlet;

[0034] The side wall of the ice discharging member facing the ice hopper abuts against the inner wall of the installation box.

[0035] In this way, the side wall of the ice discharging unit and the installation box cooperate to form a better closed environment, which is beneficial to reduce heat loss and reduce energy consumption.

[0036] In some embodiments, the first end surface is located within the orthographic projection of the side wall of the ice discharging member facing the ice hopper toward the first end surface plane.

[0037] In this way, the top wall of the ice discharging part and the installation box cooperate to form a better closed environment, and the enclosed range is larger, which is conducive to the heat of the heating wire to be transferred to the position where condensation water is generated by heat conduction in the installation box, thereby improving the anti-condensation effect.

[0038] In some embodiments, the ice discharging member is provided with an inner cavity and further comprises a heat conducting member, and the heat conducting member is provided on the inner wall of the ice discharging member.

[0039] This helps to transfer the heat of the heating wire to the outer surface of the ice gate structure more quickly, thereby helping to reduce condensation on the outer surface of the ice gate structure.

[0040] In some embodiments, the thermally conductive member may be an aluminum member.

[0041] In this way, the cost is lower and the thermal conductivity is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0076] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0077] Figure 1 It is a structural schematic diagram of an ice-discharging assembly in the related art. Figure 2 It is a cross-sectional view of an ice discharging assembly in the related art. Figure 3 It is an exploded view of the ice discharge component in the related art.

[0078] See also Figures 1 to 3 As shown, the ice discharging assembly includes an ice hopper 10, a mounting box 20, an ice door structure 30, a water receiving box 40 and an ice discharging member 50. The ice hopper 10 is located at the bottom of the ice making assembly and is communicated with the ice making assembly. The bottom of the ice hopper 10 is connected to the mounting box 20. The ice door structure 30 is located in the mounting box 20 and is connected to the mounting box 20 through a bracket 70. The ice door structure 30 rotates relative to the mounting box 20 to open or close the ice discharging port of the ice hopper 10, and the ice discharging member 50 is arranged at the bottom of the mounting box 20. The water receiving box 40 is connected to the mounting box 20, and the water receiving box 40 is embedded in the front side of the door body, and the water receiving box 40 is communicated with the ice discharging member 50.

[0079] The water receiving box 40 is provided with a switch 60 , and the switch 60 is electrically connected to the driving motor 35 .

[0080] When the user takes ice, he presses the switch 60 with the ice container, and the driving motor 35 drives the rotating shaft 36 to drive the ice door structure 30 to rotate relative to the bracket 70 to open the ice outlet. The ice-making assembly pushes the ice cubes into the ice bucket 10, and the ice cubes pass through the ice bucket 10, through the installation box 20 and the ice outlet 50, and fall into the user's ice container. When the ice container leaves the switch 60, the ice-making assembly no longer pushes out the ice cubes, and the driving motor drives the ice door structure 30 to rotate to close the ice outlet. The above process is the complete working process of the ice outlet system. It can be seen that the ice door structure 30 is a door connecting the inside and outside of the refrigerator, and when it is opened, ice cubes can be taken out of the refrigerator. Closing prevents the inside of the refrigerator from exchanging heat with the external environment, and removes condensation near the ice outlet.

[0081] Decondensation is one of the functions of the ice-making system. If the condensation in the ice-discharging system is not removed in time, it will have a great impact on the user experience.

[0082] Figure 4 for Figure 2 A partial enlarged view of point A in the middle. Figure 5 It is a schematic diagram of the structure of the ice bucket, ice door structure and ice outlet in the related art. Figure 6 It is a cross-sectional view of an ice gate structure in the related art.

[0083] To remove condensation, you need to understand the reasons for its generation. There are two reasons for the generation of condensation at the ice outlet:

[0084] 1. Cold and heat exchange. The ice door structure 30 directly connects the internal and external environments. For example, when the ambient temperature is 25°C, the humidity is 70%, and the temperature inside the ice bucket 10 is -19°C, the inner surface temperature of the ice door structure 30 is only -3.6°C. The cold energy is transferred from the inner surface of the ice door structure 30 to the outer surface of the ice door structure 30. Although it is in an environment of 25°C, its outer surface temperature is only 16 degrees, which is lower than the dew point temperature, and condensation occurs. Figure 5 As shown, the location where condensation is generated by heat exchange is mainly the outer surface shown by H.

[0085] 2. Heat conduction. The ice bucket 10 is located in the refrigerator at a temperature below -18°C, and the entire component is also below -18°C. The installation box 20 is partially in contact with the ice bucket 10, so that the local temperature of the installation box 20 is lower than the dew point temperature, resulting in condensation. Figure 4 As shown, the location where condensation occurs due to heat conduction is mainly the wall surface shown by G.

[0086] See also Figures 4 to 6As shown, the inventors have found that condensed water is generated from the outer surface of the ice door structure 30 and the inner wall surface G of the installation box 20, first gathered at the lower edge of the ice door structure 30, and then dripped onto the ice outlet 50 at the bottom of the installation box 20. The water droplets dripped onto the switch 60 through the ice outlet 50, and finally dripped into the water receiving box 40 through the switch 60 to form accumulated water waiting to be wiped or evaporated. Because the water contains impurities, water stains will be left in the path it passes through and the water receiving groove of the water receiving box 40, which greatly affects the user experience and breeds bacteria in severe cases.

[0087] In the related art, the ice door structure 30 includes an ice door box 31, a heat insulating member 32, a seal 33 and a heating film 34. The rotating shaft 36 is connected to the driving motor 35, and the rotating shaft 36 is rotatably connected to the bracket 70. The ice door box 31 is connected to the rotating shaft 36. The heat insulating member 32 is located in the area surrounded by the seal 33 and the ice door box 31. The heating film 34 is arranged on the inner wall of the ice door box 31 facing the heat insulating member 32. The ice outlet assembly uses the heating film 34 and the heat insulating member 32 to solve the problem of condensation. The driving motor 35 drives the rotating shaft 36 to drive the ice door structure 30 to rotate relative to the bracket 70 to open or close the ice outlet.

[0088] Specifically, the heating film 34 is a 0.01 mm thick film formed by a nickel-chromium alloy powder printing process. The heating film 34 is wound on the insulating tape adhesive material and pasted in the ice door box 31. The processing technology of this film heater is complicated and the manufacturing cost is high.

[0089] Moreover, during use, since the resistance value of the heating film 34 is small, the power and heat generation are small under the same current. Although the condensation on the surface of the ice door structure 30 can be removed during use, the working time is long and the power consumption is large.

[0090] Moreover, since the condensation generated by heat exchange at H can be improved by the heat insulation 32, the condensation generated by heat conduction at G can only be removed by radiation from the surface of the ice gate structure 30. The heating film 34 is far away from G, so the heat transfer effect of the heating film to G is poor, the heating time is long, and the energy consumption is large.

[0091] Also, see Figure 5 As shown, since the ice discharging member 50 does not surround the position of the ice door structure 30 near the top and the installation box G, that is, the ice door structure 30 is in a relatively open environment, part of the heat generated by the heating film 34 in the ice door structure 30 will diffuse outward through the space at the top of the ice discharging member 50 and be transferred to the installation box 20, so the heating film 34 needs to work for a long time, which consumes a lot of energy.

[0092] Figure 7 It is a cross-sectional view of another ice gate structure in the related art.

[0093] See also Figure 7 As shown, in order to overcome and reduce the cost of the heater, the heater is produced by metal wire, the heater is directly repeatedly coiled, spread and attached to the insulating tape adhesive material, and pasted in the ice door box 31. This heater is produced by metal wire drawing process, the processing technology is simple, and the manufacturing cost is low.

[0094] The metal wire can be made of nickel-chromium alloy wire. During use, due to its large resistance value, it generates more heat under the same current compared to the film heater. During use, the power-on time required to remove condensation on the surface of the ice door is short.

[0095] However, the disadvantages of this solution are obvious. The wire diameter of this nickel-chromium alloy wire heater (not shown in the figure) is 2.2mm, and the overall thickness of the heater reaches 3mm when combined with the heat-conducting material. Taking into account factors such as assembly, the thickness h of the ice door structure 30 is thicker than that of a thin-film heater by more than 5mm, which increases the volume of the ice door structure 30. At the same time, the condensation generated by heat conduction is removed by radiation from the surface of the ice door structure 30, which is far away, takes a long time to heat, and consumes a lot of energy. Moreover, the ice door structure is in a relatively open environment, and most of the heat generated by the heater is dissipated to the outside of the refrigerator, resulting in energy waste.

[0096] In order to solve the above technical problems, in the technical solution of the present application, heating wires are used instead of heating films to reduce costs.

[0097] By changing the setting position of the heating wire, compared with the heating film, the heating wire is closer to the cold source position where condensation is generated by heat transfer, thereby improving the heat transfer effect, and the heating time of the heating wire can be shorter, thereby reducing energy consumption.

[0098] Furthermore, the heating wire can be arranged on the mounting box so as to be close to the cold source where condensation is generated by heat transfer to improve the effect of heat transfer. Moreover, the thickness of the ice gate structure can be reduced.

[0099] The top wall of the ice discharging unit and the installation box cooperate to form a better closed environment, reduce heat loss and improve heating utilization.

[0125] Specifically, the ice door structure 440 is rotatably connected to the mounting bracket 430 , and the ice door structure 440 rotates relative to the mounting bracket 430 to open or close the second ice outlet 421 .

[0134] The ice door structure 440 is located in the inner cavity of the ice outlet 450 .

[0135] When the ice door structure 440 opens the second ice outlet 421, the ice cubes in the ice making assembly 300 move to the outside of the ice outlet 450 through the ice bucket 410, the first ice outlet 411, the second ice outlet 421, the fourth ice outlet, the second inner cavity and the third ice outlet 451, and finally fall into the user's ice taking container.

[0136] In some embodiments, the ice discharge assembly 400 includes a heating wire 460 .

[0137] The heating wire 460 is disposed on the installation box 420. The second ice outlet 421 is located in the area surrounded by the heating wire 460. The heating wire 460 is wound around the circumference of the second ice outlet 421.

[0138] It is understandable that the heating wire 460 is used instead of the heating film to reduce costs. Moreover, the heating wire 460 is arranged at the cold source position where condensation is generated by heat transfer. The heating wire 460 improves the effect of heat transfer by being close to the cold source position, and the heating time of the heating wire 460 can be shorter, thereby reducing energy consumption.

[0139] In some embodiments, ice dispensing assembly 400 includes a control panel 470 .

[0140] The control panel 470 is connected to the mounting bracket 430 and to the mounting box 420 .

[0141] Fig.15 This is a schematic diagram of the structure of the installation box, ice bucket and heating wire in the refrigerator provided in the embodiment of the present application. Fig.16 for Fig.15 A partial enlarged view of point C in the middle. Fig.17 This is a cross-sectional view of the installation box, ice bucket and heating wire in the refrigerator provided in the embodiment of the present application. Fig.18 for Fig.17 A partial enlarged view of point D in the middle.

[0142] See also Figures 15 to 18 As shown, in some embodiments, the heating wire 460 is disposed on the inner wall of the installation box 420. It is understandable that the heating wire 460 is disposed on the inner wall of the installation box 420, and the heating wire 460 is closer to the ice gate structure 440, which is conducive to transferring heat to the outer surface of the ice gate structure 440.

[0143] In other embodiments, the heating wire 460 is disposed on the outer wall of the mounting box 420 .

[0144] Fig.19 A schematic diagram of the structure of the installation box in the refrigerator provided in an embodiment of the present application.

[0145] See also Figures 17 to 19 As shown, in some embodiments, the inner wall of the installation box 420 is provided with a receiving portion 422. The receiving portion 422 is communicated with the first inner cavity.

[0146] The accommodating portion 422 is disposed around the second ice outlet 421. The second ice outlet is located in the area surrounded by the accommodating portion.

[0147] The accommodating portion 422 is opened toward one side of the ice door structure 440 , and the heating wire 460 is at least partially disposed in the accommodating portion 422 .

[0148] When the ice door structure 440 closes the second ice outlet 421 , the ice door structure 440 abuts against the heating wire 460 , which is beneficial for transferring heat to the outer surface of the ice door structure 440 .

[0149] In some embodiments, part of the heating wire 460 is located outside the accommodating portion 422 through the opening of the accommodating portion 422. In this way, the contact area between the ice gate structure 440 and the heating wire 460 is large, which is conducive to transferring heat to the outer surface of the ice gate structure 440.

[0150] In some embodiments, the width of the accommodating portion 422 is the same as the wire diameter of the heating wire 460 , so that it is less difficult to install the heating wire 460 in the accommodating portion 422 , and the heating wire 460 can be more firmly fixed in the accommodating portion 422 .

[0151] In some embodiments, aluminum foil or other heat-conducting components are covered on the heating wire 460. In this way, the heat transfer is facilitated by providing the heat-conducting components.

[0152] Fig. 20 A schematic diagram of the structure of an ice bucket in a refrigerator provided in an embodiment of the present application.

[0153] See also Fig.18 and Fig. 20 As shown, in some embodiments, the orthographic projection of the heating wire 460 toward the plane where the first end surface 412 of the ice bucket 410 is located is at least partially located within the first end surface 412 of the ice bucket 410. The first end surface 412 is the end surface of the ice bucket 410 facing the installation box 420.

[0154] It can be understood that the cold energy of the ice bucket 410 is transferred to the ice bucket 410 through the first end face 412. The larger the area of ​​the orthographic projection of the heating wire 460 toward the plane where the first end face 412 is located within the first end face 412, the more conducive it is to offset the cold energy of the ice bucket 410, improve the heat transfer effect, and reduce energy consumption.

[0155] In some embodiments, the orthographic projection of the heating wire 460 toward the plane where the first end surface 412 of the ice bucket 410 is located is located within the first end surface 412 of the ice bucket 410 .

[0156] In some embodiments, in order to reduce costs, the heating wire 460 is arranged in a single circle. That is, the heating wire 460 is annular, and the sum of the central angles is not greater than 360°. It should be noted that the heating wire 460 can be in a continuous ring, or the heating wire 460 can be in a ring formed by a plurality of heating segments arranged at intervals.

[0157] In some embodiments, the side wall of the ice discharging member 450 facing the ice bucket 410 abuts against the inner wall of the installation box 420. In this way, the top of the ice discharging member 450 cooperates with the installation box 420 to form a relatively closed environment, which is conducive to reducing heat loss.

[0158] In some embodiments, the first end surface 412 is located within the orthographic projection of the side wall of the ice discharging member 450 facing the ice bucket 410 toward the plane where the first end surface 412 is located. In this way, the ice discharging member 450 cooperates with the installation box 420 to form a larger and more closed environment, which is conducive to the heat of the heating wire being transferred to the location where condensation water is generated due to heat conduction in the installation box 420, thereby improving the anti-condensation effect.

[0159] In some embodiments, the heating wire 460 is provided with at least two turns, so that the heating area of ​​the heating wire 460 is larger.

[0160] In some embodiments, the heating wire 460 is a nickel-chromium alloy wire.

[0161] It can be understood that since the nickel-chromium alloy wire has a large resistance value, high power, and high heat generation, the heating time can be shortened and the power consumption is low.

[0162] In some embodiments, the heating wire 460 may be a copper wire or an iron-chromium-aluminum alloy wire.

[0163] In some embodiments, the heating wire 460 is connected to a controller of the refrigerator, and the heating wire 460 can be controlled independently by the controller.

[0164] In some embodiments, the ice discharging member 450 is provided with an inner cavity and further includes a heat conducting member (not shown in the figure), and the heat conducting member is provided on the inner wall of the ice discharging member 450 .

[0165] It is understandable that by providing a heat conductive member, the heat of the heating wire 460 can be transferred to the outer surface of the ice gate structure 440 more quickly, thereby helping to reduce condensation on the outer surface of the ice gate structure 440 .

[0166] In some embodiments, the heat conducting member may be an aluminum member, such as an aluminum foil. It is understood that the cost of an aluminum member is relatively low and the heat conducting effect is relatively good.

[0167] In some embodiments, the thermal conductor may be made of copper or other materials with high thermal conductivity.

[0168] In some embodiments, a heat preservation member is further included, and the heat preservation member is disposed on the outer wall of the ice discharging member 450. It can be understood that the heat preservation member is helpful to reduce the heat loss of the ice discharging member 450 and reduce energy loss.

[0169] Exemplarily, the thermal insulation component may be thermal insulation cotton or thermal insulation foam, etc.

[0170] In some embodiments, ice door structure 440 includes an ice door box 441 .

[0171] The ice door box 441 is rotatably connected to the installation box 420 .

[0172] Specifically, the ice door box 441 is rotatably connected to the mounting bracket 430 .

[0173] The ice door box 441 is provided with a first installation cavity 4412 .

[0174] In some embodiments, the ice door structure 440 includes a seal 442 , which is used to improve the sealing performance of the second ice outlet 421 .

[0175] The sealing member 442 is covered on the ice door box 441 . When the ice door structure 440 closes the second ice outlet 421 , the sealing member 442 abuts against the inner wall of the installation box 420 .

[0176] Exemplarily, the material of the sealing member 442 may be rubber or silicone.

[0177] In some embodiments, the ice door structure 440 includes a heat insulator 443, which is located in the first installation cavity 4412. The heat insulator 443 is used to reduce the heat exchange between the ice door structure 440 and the internal environment of the ice bin 410, increase the temperature of the outer surface of the ice door box 441, and thus reduce condensation.

[0178] The inventors conducted experiments and tests and found that by setting the heating wire 460 on the inner wall of the installation box 420 and arranging the ice discharging piece 450 around the ice door structure 440, the ice discharging piece 450 and the installation box 420 provide a relatively closed environment for the ice door structure 440, and the temperature of the inner cavity of the ice discharging piece 450 can be as high as 45°C. Compared with the ice door structure 440 using a heating film in the related art, the thickness of the heat insulating piece 443 in the ice door structure 440 in this embodiment can be thinned, thereby reducing the volume of the ice door structure 440.

[0179] Fig.21 Another cross-sectional view of the installation box, ice bucket, heating wire and ice door structure in the refrigerator provided in the embodiment of the present application, Fig. 22 for Fig.21 A partial enlarged view of point E in the middle. Fig.23 for Fig.21 Schematic diagram of the heating wire and ice gate structure.

[0180] See also Figures 21 to 23 As shown, in some embodiments, the heating wire 460 is disposed on the ice gate structure 440. It can be understood that the heating wire 460 is used to replace the heating film, which is less costly.

[0181] When the ice door structure 440 closes the second ice outlet 421, the heating wire 460 is arranged around the second ice outlet 421. In this way, the heating wire 460 is close to the cold source of condensation generated by heat transfer, thereby improving the effect of heat transfer and reducing energy consumption.

[0182] In some embodiments, the heating wire 460 is embedded in the ice gate structure 440 , which is helpful to reduce the influence of the heating wire 460 on the thickness of the ice gate structure 440 .

[0183] Fig.24 for Fig.21 Schematic diagram of the structure of the middle ice door box.

[0184] See also Fig.24As shown, in some embodiments, the heating wire 460 is located on the side of the second end surface 4413 facing the sealing member 442 , and there is a distance between the heating wire 460 and the second end surface 4413 . The second end surface 4413 is the inner bottom surface of the first installation cavity 4412 .

[0185] It is understandable that, compared with the heating wire 460 disposed on the second end surface 4413, the heating wire 460 in this embodiment is spaced apart from the first end surface 412 and is closer to the ice bucket 410. In other words, the heating wire 460 is close to the cold source position where condensation is generated by heat transfer. In this way, the effect of heat transfer is improved, and the heating time of the heating wire 460 can be shorter, thereby reducing energy consumption.

[0186] See also Figures 21 to 23 As shown, in some embodiments, the heating wire 460 is disposed on the sealing member 442 , and the heating wire 460 is disposed at one end of the sealing member 442 away from the insulation member 443 , and when the ice door structure 440 closes the second ice outlet 421 , the heating wire 460 abuts against the inner wall of the installation box 420 .

[0187] It is understandable that the inner wall of the installation box 420 is the cold source position where condensation is generated by heat transfer, and the heating wire 460 abuts against the inner wall of the installation box 420, which is conducive to better transfer of heat to the cold source position, ensuring the effect of removing condensation. In addition, the heating time can be shortened and the power consumption is low.

[0188] In some embodiments, the heating wire 460 is integrally formed with the sealing member 442. In this way, the steps of assembly can be reduced and the overall efficiency of assembly can be improved.

[0189] In some embodiments, when the ice door structure 440 closes the second ice outlet 421, the heating wire 460 is arranged around the second ice outlet 421. The orthographic projection of the heating wire 460 on the plane where the first end surface 412 of the ice hopper 410 is located is at least partially located within the first end surface 412 of the ice hopper 410. The first end surface 412 is the end surface of the ice hopper 410 facing the installation box 420.

[0191] See also Figures 25 to 27 As shown, in some embodiments, the heating wire 460 is disposed on the ice door box 441 , and the heating wire 460 is disposed at one end of the ice door box 441 facing the sealing member 442 , and the heating wire 460 abuts against the sealing member 442 .

[0192] It is understandable that, compared with the heating wire 460 disposed on the first end surface 412, the heating wire 460 is close to the cold source position where condensation is generated by heat transfer, which is conducive to improving the effect of heat transfer, and the heating time of the heating wire 460 can be shorter, thereby reducing energy consumption.

[0193] In some embodiments, a second installation cavity 4411 is disposed on the top of the ice door box 441, and the second installation cavity 4411 is opened toward one side of the sealing member 442, and a portion of the heating wire 460 is disposed in the second installation cavity 4411, and the remaining portion of the heating wire 460 is disposed outside the second installation cavity 4411 through the opening of the second installation cavity 4411. In this way, it is helpful to ensure close contact between the heating wire 460 and the sealing member 442.
