Description

Technical Field

[0001] The utility model relates to the field of refrigerators, in particular to a heating film for a stacked door or a door - in - door of a refrigerator. Background Technique

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a household product that keeps food or other items in a constant low - temperature state. Inside the box, there are a compressor and an ice maker for freezing cabinets or boxes, and a storage box with a refrigeration device. The volume of a household refrigerator is usually 20 - 500 liters.

[0003] A stacked - door or door - in - door refrigerator is a refrigerator with a special design. It adds an additional door inside on the basis of the outer door. The design of the stacked door or door - in - door increases the three - dimensional storage space of the refrigerator. However, problems such as the formation of condensed water on the surface due to the large temperature difference between the internal and external spaces of the stacked door and frosting at the outer - frame edge easily occur. Therefore, it is necessary to provide a heating film for the stacked door and door - in - door of the refrigerator to solve the above - mentioned technical problems. Summary of the Utility Model

[0004] The utility model provides a heating film for a stacked door and door - in - door of a refrigerator, which solves the problems that the design of the stacked door or door - in - door increases the three - dimensional storage space of the refrigerator, but condensed water easily forms on the surface due to the large temperature difference between the internal and external spaces of the stacked door, and frosting occurs at the outer - frame edge.

[0005] A heating film for a stacked door or door - in - door of a refrigerator, the heating film is used inside the stacked door or door - in - door of the refrigerator, and is characterized in that it includes: a heating device, and the heating device includes double - sided tape, a base material, a heating circuit, a protective film, a connector assembly, and a wire harness.

[0006] Preferably, the base material adopts a PET film, or a PI protective film can also be used.

[0007] Preferably, the heating circuit adopts a silver - carbon special - mixture paste screen - printing and etching process, and can be made of copper, aluminum, and stainless - steel alloy materials.

[0008] Preferably, the protective film adopts a PET film, or a PI protective film can also be used.

[0009] Compared with the related technology, a heating film for a stacked door or door - in - door of a refrigerator provided by the utility model has the following beneficial effects:

[0010] The utility model provides a heating film for a stacked door or door - in - door of a refrigerator. Through the mutual cooperation of the fresh - keeping door and the heating device, the heating device is installed inside the fresh - keeping door, and the heat released by the heating circuit is transferred to the surface of the fresh - keeping door to heat the fresh - keeping door, avoiding the phenomenon of condensation and icing at the connection between the fresh - keeping door and the turning beam, and having the functions of defrosting, de - icing, and anti - condensation.

[0014] First embodiment

[0015] Please refer to Figure 1 and Figure 2 .

[0016] Specifically, a heating film for a refrigerator's overlapping door or door-in-door, the heating film is used inside the refrigerator's overlapping door or door-in-door, and includes: a heating device 7, and the heating device 7 includes a double-sided tape 71, a substrate 72, a heating circuit 73, a protective film 74, a connector assembly 75, and a wire harness 76.

[0017] The substrate 72 is made of PET film, or PI protective film can also be used.

[0018] The heating circuit 73 adopts a silver-carbon special mixed paste screen printing and etching process, and can be made of copper, aluminum, and stainless steel alloy materials.

[0019] The protective film 74 is made of PET film, or PI protective film can also be used.

[0020] The heating device 7 can be installed inside the door-in-door, and the overall shape of the substrate 72 is in a "return" shape.

[0021] The working principle of a heating film for a refrigerator's overlapping door or door-in-door provided by the present utility model is as follows:

[0022] During operation, first, the substrate 72 is attached to the inside of the door-in-door through the double-sided tape 71, the wire harness 76 and the connector assembly 75 are connected to the circuit, so that the heating circuit 73 generates heat and transfers the heat energy to the surface of the fresh-keeping door.

[0023] Compared with the related art, a heating film for a refrigerator's overlapping door or door-in-door provided by the present utility model has the following beneficial effects:

[0024] The utility model provides a heating film for a stacked door or a door-in-door of a refrigerator. Through the mutual cooperation of a fresh-keeping door and a heating device 7, the heating device 7 is installed inside the fresh-keeping door, and the heat released by the heating circuit 73 is transmitted to the surface of the fresh-keeping door to heat the fresh-keeping door, avoiding the phenomenon of condensation and icing at the connection between the fresh-keeping door and the turning beam, and having the functions of defrosting, deicing and anti-condensation.

[0025] The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
