Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator accessories, in particular to a heating sheet adaptable to the curvature of the refrigerator wall. Background Art
[0002] When a refrigerator operates, the moisture contained in the air around the evaporator is likely to form frost on the surface of the evaporator in a low-temperature state. To reduce the impact of the frost on the heat exchange efficiency, i.e., the refrigeration effect, a heating sheet (electric heating) is usually used to defrost the evaporator. To meet the functions and take into account the aesthetic design, a large number of rounded and arc-shaped designs with a certain curvature are adopted for the refrigerator wall. Even if the existing heating sheet uses an easily bendable high-resistance material, such as a constantan film, after being pasted on the curved refrigerator wall for a long time, the adhesive layer will gradually become non-conforming under the action of its own resilience and heat, and even cause possible delamination, which will affect the defrosting effect. In addition, the processing technology of the existing heating sheet usually places a high-resistance material layer on the lower insulating material layer, then etches away the unnecessary circuits on the high-resistance material layer, and finally hot-presses the upper insulating material layer on the lower insulating material layer, so as to encapsulate the high-resistance material layer between the two insulating material layers. Limited by this process, the size of the heating sheet needs to be customized according to the size of a specific refrigerator, otherwise the defrosting and dewatering effects will be reduced. It can be seen that the existing heating sheet still has low versatility. Summary of the Utility Model
[0003] The main purpose of the utility model is to provide a heating sheet adaptable to the curvature of the refrigerator wall, which can effectively solve the problems in the background art.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A heating sheet adaptable to the curvature of the refrigerator wall includes a heating sheet body and a shaping layer connected to the top end of the heating sheet body;
[0006] The shaping layer includes two horizontally arranged shaping bags spaced apart from front to back, and horizontal inlets are provided through both the left and right ends of the horizontal shaping bags;
[0007] The shaping layer further includes a plurality of vertical shaping bags located between the two horizontal shaping bags, the plurality of vertical shaping bags are spaced apart from left to right, and vertical inlets are provided through both the front and back ends of the vertical shaping bags;
[0008] It further includes a shaping plate that can be placed into the horizontal shaping bag or the vertical shaping bag.
[0009] Furthermore, a through channel communicating with the horizontal shaping bag is provided on the horizontal shaping bag.
[0010] Further, the heating sheet body includes a heating sheet adhesive layer, a first insulating material layer, a conductive and heating layer, and a second insulating material layer, which are connected in sequence from bottom to top.
[0011] Further, the conductive and heating layer includes uniformly arranged heating resistance circuits;
[0012] Both ends of the heating resistance circuit are respectively connected to the same conductive plug through a first external conductive circuit penetrating the second insulating material layer.
[0013] Further, two internal conductive circuits are connected in parallel at both ends of the heating resistance circuit, and the heating resistance circuit is located in the area between the two internal conductive circuits;
[0014] Both ends of the internal conductive circuit are respectively connected to the same conductive socket capable of being connected to the conductive plug through a second external conductive circuit penetrating the second insulating material layer, and the conductive socket and the conductive plug are in a parallel connection relationship.
[0015] Further, sleeving tubes are sleeved on both the two first external conductive circuits and the two second external conductive circuits.
[0016] Further, the heating sheet adhesive layer is selected as double-sided tape;
[0017] The heating resistance circuit is selected to be made of constantan material;
[0018] The internal conductive circuit is selected to be made of conductive ink material;
[0019] The first insulating material layer, the second insulating material layer, and the shaping layer are all selected to be made of polyimide film material.
[0020] Compared with the prior art, the utility model has the following beneficial effects: In the utility model, according to the position where the heating sheet body is pasted and the required bending direction, a horizontal shaping bag or a vertical shaping bag is selected to place the shaping plate. The shaping plate can assist in supporting the heating sheet body to fit on the refrigerator wall, reducing the probability of its debonding. Specifically, when the heating sheet body needs to be bent forward and backward, a shaping plate with a specific bending degree is placed into the vertical shaping bag; when the heating sheet body needs to be bent left and right, a shaping plate with a specific bending degree is placed into the horizontal shaping bag. In this way, the stability of the heating sheet fitting can be effectively improved. In addition, through the parallel connection and cooperation of the conductive socket and the conductive plug, the heating sheets described in this embodiment can be combined according to the size of the refrigerator to achieve the corresponding length and width. At the same time, by placing a suitable shaping plate into the horizontal shaping bag or the vertical shaping bag on a specific heating sheet, the specific bending degree requirement of the refrigerator wall can be met. In this way, the versatility of the heating sheet application can be greatly improved, and further the effect of reducing production costs can be achieved. Description of the Drawings

The plurality of vertical shaping bags 3 are arranged at intervals in the left-right direction, and vertical inlets 5 are provided through both the front and rear ends of the vertical shaping bags 3;
[0034] It further includes a shaping plate 6 that can be placed into the horizontal shaping bag 2 or the vertical shaping bag 3.
[0035] In this embodiment, the shaping plate 6 can select a suitable shape according to the size and curvature of the refrigerator wall, and select the horizontal shaping bag 2 or the vertical shaping bag 3 to place the shaping plate 6 according to the position where the heating element body 1 is attached and the required bending direction. The shaping plate 6 can assist in supporting the heating element body 1 to be attached to the refrigerator wall and reduce the probability of its delamination.
[0036] Take Figure 1 as an example. When the heating element body 1 needs to be bent in the front-rear direction, a shaping plate 6 with a specific curvature is placed into the vertical shaping bag 3, as shown in Figure 4 ; when the heating element body 1 needs to be bent in the left-right direction, a shaping plate 6 with a specific curvature is placed into the horizontal shaping bag 2, as shown in Figure 3 .
[0037] It can be seen that through the setting of the horizontal shaping bag 2 and the vertical shaping bag 3 in this embodiment, the requirements for curvatures in different directions can be met, and the versatility of the application of this embodiment can be effectively improved.

In this way, the middle region of the shaping plate 6 is supported and limited by the vertical shaping bag 3, and the two end portions of the shaping plate 6 are supported and limited by the horizontal shaping bag 2. In this way, the shaping plate 6 can better support the heating element body 1.

[0047] In this embodiment, the conductive socket 16 and the conductive plug 14 can be respectively located at the left and right ends of the heating sheet body 1, and the conductive plug 14 can be inserted and matched with the conductive socket 16. The two second external conductive circuits 15 are respectively welded to the two internal conductive circuits 12 to form two second solder joints 20.
