Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator accessories, in particular to a heating component for defrosting and dewatering a refrigerator. Background Art

[0002] When the refrigerator is running, the moisture contained in the air around the evaporator is easy to form frost on the surface of the evaporator in a low-temperature state. In order to reduce the impact of the frost on the heat exchange efficiency, that is, the refrigeration effect, the evaporator is usually defrosted by an electric heater. In order to quickly realize the conversion between electrical energy and thermal energy, some advanced defrosting heating plates use high-resistance materials, such as constantan film, which can improve the problem of difficult bending and low safety of traditional heating wires; at the same time, it is also equipped with special insulating materials to make the defrosting heating plate have good insulation performance and energy transfer efficiency. The processing technology of this heating plate is usually to place a high-resistance material layer on the lower insulating material layer, then etch away the unwanted lines on the high-resistance material layer, and finally hot-press the upper insulating material layer on the lower insulating material layer, so that the high-resistance material layer is encapsulated between the two insulating material layers. Limited by this process, the size of the heating plate needs to be customized according to the size of the specific refrigerator, otherwise the defrosting and dehydrating effect will be reduced. It can be seen that compared with traditional heating wires, the existing heating plates have lower versatility, which will increase the cost investment of manufacturers and cannot take into account the balance between low cost and practicality and high efficiency.

[0038] The two ends of the heating resistor circuit 8 are respectively connected to the same connection plug 4 through the first external conductive circuit 3 penetrating the heating sheet 1, and the two ends of the internal conductive circuit 9 are respectively connected to the same connection socket 10 through the second external conductive circuit 12 penetrating the heating sheet 1, and the connection plug 4 and the connection socket 10 are in parallel connection relationship;

[0039] The connection socket 10 and the connection plug 4 are respectively located at the left and right ends of the heating sheet 1 , and the connection plug 4 can be inserted and matched with the connection socket 10 .

[0040] In this embodiment, the two first external conductive circuits 3 are respectively welded to the two ends of the heating resistor circuit 8 to form two first tin contacts 7; the two second external conductive circuits 12 are respectively welded to the two internal conductive circuits 9 to form two second tin contacts 11.

[0041] Preferably, the two first external conductive circuits 3 and the two second external conductive circuits 12 are sleeved with a bundle tube 5. The bundle tube 5 can protect the first external conductive circuits 3 and the second external conductive circuits 12, and can also improve the stability of the connection between the connecting plug 4 and the two first external conductive circuits 3, and between the connecting socket 10 and the two second external conductive circuits 12.

[0042] When this embodiment is used, it is also necessary to be equipped with a driving power supply, which has a driving socket that can be adapted to the connecting plug 4. The driving socket can refer to the connecting socket 10. The driving power supply has a voltage step-down module to provide a voltage suitable for the heating of the heating resistor circuit 8 in each heating plate 1.

[0043] Preferably, the heating sheet 1 comprises a heating sheet adhesive layer 13, a first insulating material layer 14, a conductive and heating layer 15, and a second insulating material layer 16 which are sequentially connected from back to front;

[0044] The heating resistor circuit and the two internal conductive circuits 9 together form the conductive and heating layer 15 .

[0045] Preferably, the heating resistor circuit 8 is made of constantan;

From the outside, the state of the heating resistor circuit 8 and the internal conductive circuit 9 can be seen through the second insulating material layer 16. Figure 3 .

[0048] In this embodiment, the heating resistor circuit 8 and the internal conductive circuit 9 are arranged between two insulating material layers, which can provide operational reliability and safety.

[0049] Preferably, it comprises at least two heating sheet groups;

[0050] The connection plug 4 of one heating chip group of two adjacent heating chip groups is inserted and matched with the connection socket 10 of the other heating chip group.

[0051] When used, a suitable number of heating sheet groups can be selected according to the size of the refrigerator, and the heating sheet groups can be connected in series through the connection plug 4 and the connection socket 10 to achieve the required length. Such a design can greatly improve the versatility of the heating sheet 1.

[0052] Among them, the heating plate adhesive layer 13 is used to bond to the refrigerator shell. When power is supplied, the heating resistor circuit 8 in each heating plate group converts electrical energy into thermal energy, and the thermal energy is transferred to the refrigerator shell through the first insulating material layer 14 and the heating plate adhesive layer 13 to achieve the effect of removing frost.

[0053] Preferably, it further comprises a positioning member 6, the rear end of which is provided with a rotating adhesive layer 66, and the rear end of which is also provided with two groups of positioning head groups passing through the rotating adhesive layer 66;

[0055] Preferably, the positioning head group includes three positioning heads 63 arranged at intervals, and correspondingly, the positioning groove group includes three positioning grooves 2 respectively matched with the three positioning heads 63.

[0056] In this embodiment, the positioning member 6 is used to locate the joint positions of two adjacent heating plate groups, so as to control the joint spacing of each heating plate group, thereby achieving a uniform heating effect.

[0057] The positioning head group and the positioning groove group cooperate to realize rapid positioning. In order not to affect the bonding between the heating sheet adhesive layer 13 and the refrigerator shell, the positioning groove 2 passes through the first insulating material layer 14, the conductive and heating layer 15, and the second insulating material layer 16.

[0058] The rotating adhesive layer 66 can be a double-sided adhesive tape or a smeared glue.

[0059] For easy operation, the rotating adhesive layer 66 is made of double-sided tape. When using it, first tear off the release paper of the rotating adhesive layer 66, then align the two positioning head groups with the two positioning groove groups on the two adjacent heating plates 1, and bond the positioning member 6 to the second insulating material layer 16 of the two heating plate groups. At this time, the positioning head 63 is placed in the positioning groove 2, and the bottom end of the positioning head 63 is in contact with the heating plate adhesive layer 13.

[0060] When used, positioning grooves can be provided around the heating sheet 1, so that the heating sheet groups can be spliced ​​not only in length but also in width. Figure 8 As shown, four heating sheet groups can be connected in series along the direction of ABCD.

[0061] Preferably, the positioning member 6 comprises two positioning plates 62 arranged opposite to each other, the two positioning plates 62 are hingedly connected by a hinge 61, the rear ends of the two positioning plates 62 are both provided with the rotating adhesive layer 66, and the rear ends of the two positioning plates 62 are both provided with the positioning head group.

[0063] Preferably, a card slot seat 64 is provided at the front end of the positioning member 6 , and the card slot seat 64 has a card slot 65 that can be card-engaged with the connecting plug 4 or the connecting socket 10 .

[0064] In this embodiment, the card slot seat 64 is provided to position the connecting plug 4 and the connecting socket 10. Firstly, it can prevent the connecting plug 4 and the connecting socket 10 from being suspended in the air and maintain the stability of the connection between the connecting plug 4 and the connecting socket 10. Secondly, it can facilitate the arrangement of the circuits and avoid affecting the operation of the heating plate 1.

[0065] Preferably, the card slot seat 64 can be detachably connected to the positioning member 6. In this way, when there is no need to position the connecting plug 4 and the positioning member 6 for connecting the socket 10, the card slot seat 64 can be removed, and only the function of positioning the two heating plate groups is retained. Figure 8 shown.

[0066] When multiple heating sheet groups are connected in series, the first external conductive circuit 3 and the second external conductive circuit 12 need to have sufficient length to support the connection plug 4 and the connection socket 10 to be snapped onto the adjacent slots 64 .

[0067] like Figure 5 As shown, when the positioning member 6 has two hinged positioning plates 62 , each positioning plate 62 may be provided with a slot seat 64 .
