Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration appliances, in particular to a refrigeration appliance glass door body based on internal auxiliary heating arrangement. Background Art
[0002] The existing hollow glass door of the refrigeration device solves the condensation phenomenon of the outer layer of the door by electrically heating the glass door. The two electrodes of the heating wire are long strips of metal, and the middle is the heating main component of SnO 2 Coating (not limited to SnO 2 ), the coating is evenly coated on the inside of the glass, and the coating heating wire is generally uniform, so the heating surface of the entire door body is uniform.
[0003] In the actual operation of the refrigerator, the temperature of the upper and lower parts of the door body is different, but the glass door heating wire used is Figure 1 As shown in the distribution, the heating surface of the entire door is uniform.
[0004] However, the lower part of the glass door of the refrigeration device has a relatively low temperature due to the sinking of cold air in the refrigeration room, and the condensed water vapor will gather under the door due to gravity. In order to prevent condensation as a whole, the heating power required at the bottom is relatively high, but the power of the heating wire on the surface of the current glass door is uniform, so under the same heating power, there may be no condensation on the top of the glass door, but condensation water droplets on the lower part of the glass door, especially because the splicing of the glass and the door frame cannot be guaranteed to be completely simulated, which makes it particularly obvious at the edge of the lower door. The current common improvement method is to increase the heating power, but this method will cause the upper door body to overheat, affect the power consumption of the whole machine, affect the temperature inside the box, and because the heater power is increased, the controller load capacity needs to be increased, resulting in a series of problems such as increased cost of the whole machine.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0019] like Figure 1The following is a common structure diagram of the anti-condensation method for hollow glass doors.

The condensation problem can be solved by increasing the coating power supply voltage or reducing the glass coating resistance, but this solution increases the power consumption and cost of the whole machine and cannot be effectively controlled.
