Description

Technical Field

[0001] The utility model relates to the technical field of anti-condensation of a middle beam of a refrigerator, in particular to an anti-condensation structure of a middle beam of a refrigerator. Background Art

[0002] Refrigerators can preserve freshness and freeze food. They are widely used in various fields such as home, business and medical. The center beam of the refrigerator is the partition structure between the upper and lower inner tanks. It is prone to condensation during use. Based on this, it is often necessary to set a structure to prevent condensation on the center beam on the refrigerator.

[0003] There are often three types of anti-condensation structures in the existing refrigerator center beams, all of which have some defects. First, adding an anti-condensation pipe to the center beam has high requirements on the production process. The anti-condensation pipe needs to be foamed to make way, the production process is complicated, and the production efficiency is low. Second, adding an electric heating wire to the center beam has safety hazards. During use, leakage and fire often occur due to aging. Third, adding electric heating to the door body at the center beam. The heating surface of this method does not directly act on the center beam, and it is still difficult to completely solve the problem in harsh environments. Therefore, we propose a new type of anti-condensation structure for the refrigerator center beam, which takes into account both dew removal effect and safety, so as to improve product quality.

[0014] (1) This technical solution optimizes the performance of the device by installing a first active side anti-condensation plate and a second active side anti-condensation plate. On the one hand, by utilizing the weak electric heating wires arranged inside the first active side anti-condensation plate and the second active side anti-condensation plate and the heating function of the aluminum alloy back plate on the back, combined with the power supply function of the low-temperature resistant lithium battery board inside the waterproof casing, a self-powered active heating anti-condensation protection function can be realized, thereby solving the safety hazard of adding electric heating wires to the middle beam. During use, this method is inconvenient to wire and the wires will age and leak and catch fire. It also solves the problem of adding electric heating to the door body at the middle beam, which leads to The heating surface does not directly act on the middle beam and the anti-condensation effect is poor.

On the other hand, the user can use the clamping effect between the sealing cover and the waterproof casing to regularly replace and charge the low-temperature resistant lithium battery panel.
