Description

Technical Field

[0001] This utility model relates to the field of refrigerator door technology, and in particular to a glass door for a refrigeration appliance based on an auxiliary heating arrangement. Background Technology

[0002] Existing refrigeration devices generally solve the condensation problem on the outside of the glass door by adding a conductive film to the inside of the glass and heating the inner conductive film. Two long strip metal electrodes are led out from the inside of the glass, either left and right or top and bottom, with a conductive film evenly covered between the two electrodes.

[0003] Because the conductive film on the entire door is uniform, the glass temperature after heating at room temperature is also uniform. Due to the sinking of cold air inside the refrigeration chamber, and the accumulation of condensed water vapor at the bottom of the door due to gravity, the lower layer of glass is colder, leading to condensation. To prevent condensation, a higher heating power is required at the bottom. However, current glass door surface heating wires have uniform power, so with the same heating power, there may be no condensation at the top of the glass door, but condensation droplets at the bottom. This is especially noticeable at the lower door edges because the glass and door frame cannot be perfectly aligned, causing water to accumulate in the gaps between them and preventing rapid evaporation. The common solution is to increase the heating power, but this leads to overheating of the upper door, affecting overall power consumption and internal temperature. Furthermore, increased heater power requires a larger controller, increasing overall cost. Therefore, a solution is urgently needed.

[0021] Example

[0022] See Figure 1-4 As shown:

[0023] This utility model provides a glass door for a refrigeration appliance based on an auxiliary heating arrangement, including: heatable glass 10, door frame 20 and heating components.

[0024] In practical applications, the heatable glass 10 is embedded in the door frame 20, making it easy to observe the inside of the refrigerator from the outside without opening the refrigerator. The heating component is installed on the door frame 20 and located at the bottom of the heatable glass 10, so as to directionally heat and evaporate the condensation that condenses at the bottom of the heatable glass 10, thus solving the problem of condensation at the bottom of the glass refrigerator door.

[0025] There are two main solutions for heating components that provide directional heating and promote the rapid evaporation of condensation.

[0026] The heating assembly includes a U-shaped heating element 51. The U-shaped heating element 51 is disposed at the connection between the bottom of the heatable glass 10 and the door frame 20. One side of the U-shaped heating element 51 is attached to the door frame 20, and the other side is attached to the heatable glass 10, forming a parallel circuit with the heating wire on the heatable glass 10.

[0027] With this setup, the temperature generated by the heating element can be directly transferred to the heatable glass 10 simply by turning on the power; and the heating element and the door frame 20 have a certain contact area, which can effectively increase the temperature of the door frame 20 at the corresponding position and reduce the risk of condensation around the lower layer of the glass door.

[0028] For glass doors where condensation is not severe, the heating assembly mainly consists of a pressure strip 30, a sealing strip 40, and an electric heating element 52.

[0029] A mounting groove is typically provided on the door frame 20, located at the connection between the bottom of the heated glass 10 and the door frame 20. It also includes bolts 33; bolt holes are provided in the mounting groove; through holes are provided at both ends of the pressure strip 30; the bolts 33 pass through the through holes and form a detachable connection with the bolt holes in the mounting groove. When maintenance is required, disassembly can be completed simply by unscrewing the bolts 33.

[0030] The pressure strip 30 is snap-fitted into the mounting groove, and the pressure strip 30 is fitted to the bottom edge of the heatable glass 10. The top of the pressure strip 30 is provided with a water collection platform 32 to collect condensation. A sealing strip 40 is provided at the connection between the pressure strip 30 and the heatable glass 10 to seal the gap between the pressure strip 30 and the heatable glass 10 and to guide the condensation at the bottom of the heatable glass 10 to the water collection platform 32. An electric heating element 52 is provided in the pressure strip 30.

[0031] An L-shaped groove 31 is provided in the pressure strip 30; the L-shaped groove 31 is used to connect the water accumulation platform 32 and the bottom edge of the heatable glass 10; the electric heating element 52 is set in L-shape and is installed in the L-shaped groove 31, and heats the water accumulation platform 32 and the bottom edge of the heatable glass 10 simultaneously; the electric heating element 52 and the heating wire on the heatable glass 10 form a parallel circuit.

[0032] In practical applications, due to gravity, some of the condensation on the glass door slides along the surface of the glass door to the sealing strip 40, and flows to the water accumulation platform 32 under the guidance of the sealing strip 40. Thus, under the action of the electric heating element 52, the condensation on the water accumulation platform 32 and around the bottom edge of the heatable glass 10 can be heated simultaneously, causing the condensation to be heated and evaporate quickly.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
