Description

Technical fields:

[0001] This utility model relates to a PVC back panel structure for a refrigerator with a decondensation tube, which belongs to the field of household appliance technology. Background technology:

[0002] In the current refrigerator industry, the back panel is primarily made of metal. Metal back panels are widely used in high-end refrigerators due to their high flame retardancy and thermal conductivity. Built-in refrigerators, in particular, almost exclusively use metal back panels because they are prone to condensation. However, the higher cost of metal back panels contributes to the overall higher price of the refrigerator. One solution is to use PVC back panels instead of metal. However, PVC back panels have relatively poor thermal conductivity, leading to ineffective conduction of condensation and causing condensation problems.

[0003] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Utility Model Content:

[0004] This utility model provides a refrigerator PVC back panel structure with a decondensation pipe to solve the problems existing in the prior art, which can solve the condensation problem that occurs when a PVC back panel is used in an embedded refrigerator.

[0005] The present invention adopts the following technical solution: a refrigerator PVC back panel structure with a decondensation tube, including a PVC back panel, the PVC back panel having grooves formed in the recess, each groove having a stepped portion on both sides, a decondensation tube placed in the groove, and aluminum foil being attached and fixed to the PVC back panel above the decondensation tube.

[0006] Furthermore, the diameter of the dew removal pipe is D, and the depth of the trench is h, where D / 2 < h < D.

[0007] Furthermore, the groove width is L1, where L1 > D.

[0008] Furthermore, the width of the step portion is L2, and the width of the aluminum foil 3 is L3, where L1 + 2 * L2 < L3.

[0009] The present invention has the following beneficial effects: The refrigerator PVC back panel structure with condensation tube attached can solve the condensation problem of the PVC back panel of the built-in refrigerator, realize the use of PVC back panel to replace metal back panel in built-in refrigerator, and reduce the overall cost of refrigerator products.

[0012] The utility model will be further described below in combination with the drawings.

[0013] The utility model discloses a refrigerator PVC backplate structure that has dew removal pipe pasting, including PVC backplate 1, the recessed formation has the groove 10 on PVC backplate 1, and the step portion 11 is formed to both sides of each groove 10. The dew removal pipe 2 is placed in the groove 10, and the aluminum foil 3 is fixed and pasted on the position of PVC backplate 1 and located above the dew removal pipe 2.

[0014] The diameter of dew removal pipe 2 is D, the groove depth height of groove 10 is h, the groove width is L1, the step portion width is L2, and the pasting width of aluminum foil 3 is L3. To realize the fixed limiting action of PVC backplate 1 to dew removal pipe 2, it requires D / 2 < h < D. L1 > D can realize that dew removal pipe 2 is clamped into the groove 10 of PVC backplate and is limited, avoids that the pipeline layout is uneven due to the non-limiting dew removal pipe 2, and influences the heat conduction effect of PVC backplate 1.

[0015] The structure size of aluminum foil 3 pasting place should satisfy L1+2*L2 < L3, to ensure that the heat conduction in the pasting range of aluminum foil 3 is as much as possible, prevents the condensation problem caused by the insufficient pasting width of aluminum foil 3 and the insufficient heat conduction of PVC backplate 1.

[0016] The utility model discloses a refrigerator PVC backplate structure that has dew removal pipe pasting, and the working principle is as follows:

[0017] 1. when the refrigerator is normally operated, the refrigerant runs in the refrigeration system of the refrigerator, and the high-temperature refrigerant in the refrigerator runs through the dew removal pipe 2, so that the heat of the refrigerator refrigeration system is transferred to the dew removal pipe 2.

[0018] 2. the dew removal pipe 2 and PVC backplate 1 are pasted and fixed through aluminum foil 3, and the heat of dew removal pipe 2 is conducted to PVC backplate 1, to prevent the condensation caused by the local temperature being too low.

[0019] 3. by controlling the texture of PVC backplate 1, the layout position of dew removal pipe 2 can be adjusted, which can effectively prevent the low-temperature condensation caused by the local cold conduction of PVC backplate 1.

[0020] 4. to prevent the gap cavity between aluminum foil 3 and groove 10 from being too large and causing abnormal refrigerator high-low temperature experiment, the air hole is increased in the groove 10 of PVC backplate 1.

[0021] The above merely describes preferred embodiments of the present application, and it should be noted that those of ordinary skill in the art can make several improvements without departing from the principles of the present application, and these improvements should also be considered within the protection scope of the present application.
