[0045] At present, multi-door refrigerators are becoming more and more popular among domestic and foreign consumers. Among the multi-door refrigerators in the market, the main concept of the cross-door refrigerator is large-capacity storage in the refrigerator compartment and zoned storage in the freezer compartment; the main concept of the French-door refrigerator is large-item storage in both the refrigerator compartment and the freezer compartment.
[0046] In existing multi-door refrigerators, due to differences in the door bodies, it is necessary to add partition plates inside the refrigerator to prevent cold leakage. However, the partition plates will reduce the available volume of the refrigerator. For this reason, related technologies have proposed a flip beam to maximize the available volume of the refrigerator while ensuring its performance. However, due to the large temperature difference between the inside and outside of the refrigerator, ice may form at both ends of the flip beam due to cold leakage, resulting in the inability to open the flip beam.
[0047] Based on this, the present utility model provides a heating structure for the flip beam of a refrigerator, aiming to solve the problem that the flip beam cannot be opened due to ice formation at both ends. Among them, Figure 1 is a schematic structural diagram of the heating structure provided by the present utility model; Figure 2 is a schematic structural diagram of the flip beam provided by the present utility model.
[0048] Please refer to Figure 1 and Figure 2 In an embodiment of the present utility model, the heating structure 100 includes a main heating part 1 extending in a first direction, and a folded-edge heating part 2 connected to the end of the main heating part 1. The folded-edge heating part 2 extends in a third direction, wherein the first direction is orthogonally arranged with the third direction.
[0049] In the technical solution of the present utility model, by providing the main heating part 1 to heat the flip beam 1000, and by providing the folded-edge heating part 2, the heating structure 100 can heat the end of the flip beam 1000, so as to prevent the flip beam 1000 from being unable to open due to ice formation at the end, thus solving the problem that the flip beam 1000 cannot be opened due to ice formation at both ends.
[0050] It should be noted that the first direction can be the up-down direction or the left-right direction, etc. The present utility model does not make any limitations in this regard. Exemplarily, the first direction is the length direction of the flip beam 1000.
[0051] In an embodiment of the present utility model, the main heating part 11 includes a first heating part 11 and a second heating part 12 distributed along the first direction. Corresponding to the same length of the heating structure 100 along the first direction, the heating area of the first heating part 11 is larger than that of the second heating part 12. In this way, by arranging multiple heating parts, the heating structure 100 can heat the turnover beam 1000 of the refrigerator. At the same time, multiple heating parts include the first heating part 11 and the second heating part 12. Corresponding to the same length of the heating structure 100 along the first direction, the heating area of the first heating part 11 is larger than that of the second heating part 12, so that the first heating part 11 and the second heating part 12 with different heat generation amounts can be formed along the first direction of the heating structure 100, making the heat of the heating structure 100 on the turnover beam 1000 at the air outlet of the refrigerator larger and the heat on the turnover beam 1000 not at the air outlet smaller, so that the heat distribution of the heating structure 100 can adapt to the temperatures of the turnover beam 1000 at different positions, in order to balance the temperature difference of the turnover beam 1000 and keep the temperature on the surface of the turnover beam 1000 consistent.
[0052] It should be noted that corresponding to the same length of the heating structure 100 along the first direction, the fact that the heating area of the first heating part 11 is larger than that of the second heating part 12 means that on the unit length along the first direction, the heating area of the first heating part 11 is larger than that of the second heating part 12. In this way, the heat generation amount of the first heating part 11 is larger than that of the second heating part 12, so that the heat generation amounts of the heating structure 100 at different positions in the first direction are different, in order to adapt to the temperatures of the turnover beam 1000 at different positions.
[0053] In an embodiment of the present utility model, the heating structure 100 includes a heating wire. The total length of the heating wire in the first heating part 11 is longer than that in the second heating part 12. In this way, by arranging the heating wire, the first heating part 11 and the second heating part 12 can be integrally formed. At the same time, the total length of the heating wire in the first heating part 11 is longer than that in the second heating part 12, so that the heat generation amount of the first heating part 11 can be larger than that of the second heating part 12, making the heat generation amounts of the heating structure 100 at different positions in the first direction different.
[0054] It should be noted that there are various types of the heating structure 100. In another embodiment, the heating structure 100 includes a heating wire and a heating plate arranged along a first direction. Among them, the first heating part 11 includes the heating plate, and the second heating part 12 includes the heating wire. In this way, through the combination of the heating wire and the heating plate, the heating structure 100 is formed.
[0055] In an embodiment of the present invention, at least a part of the wire segment of the heating wire located within the first heating part 11 is bent and extends. In this way, the heating wire is bent so that the length of the heating wire of the first heating part 11 is greater than the length of the heating wire of the second heating part 12, thereby making the heat generation amount of the first heating part 11 greater than the heat generation amount of the second heating part 12. Further, there are various ways of bending the heating wire. For example, it can be bent in an S shape or in a rectangular shape, etc. The present invention does not limit this.
[0056] Further, the number of the first heating parts 11 is not limited. It can be one or multiple, etc., and can be specifically adjusted according to needs. Specifically, in this embodiment, multiple first heating parts 11 are provided. The multiple first heating parts 11 include two first end heating parts 111 at both ends in the first direction. The folded-edge heating part 2 is connected to the first end heating part 111. Since the two ends of the turning beam 1000 usually correspond to the air outlets of the refrigerator, the two first end heating parts 111 are correspondingly arranged at both ends of the heating structure 100 so that the two first end heating parts 111 can be arranged corresponding to the two ends of the turning beam 1000, enabling the two first end heating parts 111 with higher heat generation amounts to heat the two ends of the turning beam 1000.
[0057] In an embodiment of the present invention, the multiple first heating parts 11 further include a first intermediate heating part 112 located between the two first end heating parts 111. Since a wire-passing rotating shaft 500 for the heating wire to pass through is generally provided in the middle of the turning beam 1000, making the temperature in the middle of the turning beam 1000 relatively low, by providing the first intermediate heating part 112, the first intermediate heating part 112 with a higher heat generation amount can heat the middle of the turning beam 1000 to balance the temperature difference of the turning beam 1000.
[0058] In an embodiment of the present utility model, two connection terminals 13 are formed at the end of the heating wire. The two connection terminals 13 are arranged in parallel and are led out corresponding to the first intermediate heating part 112. In this way, the two connection terminals 13 can be led out from the middle of the flipping beam 1000, so that the heating wire can be connected to a power source outside the flipping beam 1000. Of course, in other embodiments, the two connection terminals 13 can also be led out from the two ends of the heating structure 100 respectively, etc. The present utility model does not make any limitations in this regard.
[0059] In an embodiment of the present utility model, the heating structure 100 includes a heating wire. The heating wire on at least one of the first end heating parts 111 is bent back and forth along the second direction. Some wire segments on the first end heating part 111 are bent and extended along the third direction to form a folded-edge heating part 2 extending in the third direction. Among them, the first direction, the second direction, and the third direction are orthogonally arranged. In this way, the heating wire is bent back and forth along the second direction, so that the length of the heating wire of the first end heating part 111 is greater than the length of the heating wire of the second heating part 12, making the heat generation amount of the first end heating part 111 greater than the heat generation amount of the second heating part 12. At the same time, some heating wires of the first end heating part 111 are bent to form the folded-edge heating part 2, which not only enables the heating structure 100 to heat the end of the flipping beam 1000 to prevent the end of the flipping beam 1000 from freezing and causing the flipping beam 1000 to be unable to be opened, but also enables the folded-edge heating part 2 to be integrally formed with the main heating part 1, saving subsequent assembly processes.
[0060] It should be noted that there are various types of the first direction, the second direction, and the third direction. For example, the first direction can be the up-down direction, the second direction can be the front-back direction, and the third direction can be the left-right direction, etc. Or the first direction can be the left-right direction, the second direction can be the front-back direction, and the third direction can be the up-down direction, etc. The present utility model does not make any limitations in this regard. Exemplarily, the first direction is the length direction of the flipping beam 1000, the second direction is the width direction of the flipping beam 1000, and the third direction is the thickness direction of the flipping beam 1000. Further, there are various bending directions of the heating wire. In other embodiments, the heating wire on the first end heating part 111 is bent back and forth along the first direction.
[0061] In an embodiment of the present utility model, the heating structure 100 includes a heating wire. At least a part of the wire segment of the heating wire located in the first heating portion 11 is bent and extends to form a bent and extended wire segment. On different first heating portions 11, the bent and extended segments are arranged oppositely along a first direction. In this way, the first heating portions 11 at different positions are bent in the same direction, so that the heating wire can be arranged flush, thereby helping to reduce the thickness of the heating structure 100 and facilitating the attachment of the heating structure 100 to the flipping beam 1000.
[0062] In an embodiment of the present utility model, the heating structure 100 includes a heat conducting member 2 attached to one side of the heating wire. The heat conducting member 2 extends along the first direction. In this way, by providing the heat conducting member 2, the heat of the heating structure 100 can be balanced to prevent local overheating or overcooling of the heating structure 100. Further, there are various types of heat conducting members 2. For example, the heat conducting member 2 can be a heat conducting copper sheet or a heat conducting aluminum sheet, etc. The present utility model does not limit this. Specifically, in this embodiment, the heat conducting member 2 includes a heat conducting aluminum foil. In this way, by using the heat conducting aluminum foil, the heat of the heating structure 100 can be transferred and it can be attached to the heating structure 100 to form an integral part with the heating structure 100.
[0063] In an embodiment of the present utility model, the heat conducting member 2 and the heating wire are arranged in a thermocompression molding manner. In this way, by using the thermocompression molding method, the heat conducting member 2 and the heating wire are integrally formed, which is convenient for molding and has a firm combination. Of course, in other embodiments, the heating wire and the heat conducting member 2 can also be adhesively connected, etc. The present utility model does not limit this.
