[0002] In the field of refrigeration technology, glass door refrigerators are widely used in commercial places such as supermarkets and convenience stores due to their good display effect and convenient access. However, there is a common and difficult problem in the use of traditional sliding glass doors, namely condensation. Due to the temperature difference between the inside and outside of the glass door, water vapor will condense on the glass surface to form water droplets or mist, causing the door surface to be blurred, seriously affecting the display effect and customer experience.
[0003] In order to solve this problem, the industry has made many attempts, such as increasing the sealing of the door body, using double-layer or hollow glass, etc. However, these methods are either limited in effect or expensive and difficult to promote widely. In particular, the traditional heating method usually requires the heating device to be embedded in the double-layer door body, which not only increases the manufacturing cost and construction difficulty, but also the heating effect is often unsatisfactory, and there are problems such as uneven heating and high energy consumption. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides a sliding glass door with electric heating, such as Figure 1-Figure 6 As shown, it includes a cabinet body 1, a cabinet door 2 is slidably installed on the top of the cabinet body 1, a heating film 28 is installed on the inner surface of the cabinet door 2, a cabinet opening terminal 11 is installed at the cabinet opening of the cabinet body 1 near the cabinet door 2, a bracket 22 is arranged on the inner side of the frame 210 of the cabinet door 2, the middle part of the bracket 22 is positioned by a pull rod 24, and the end of the bracket 22 is connected to the heating film 28 through a heating wire 26. When the cabinet door 2 is closed, the bracket 22 can be connected to the cabinet opening terminal 11, thereby realizing the electrical heating of the heating film 28.
[0024] In this embodiment, a terminal switch 21 is installed at one end of the bracket 22, and a power supply terminal 27 is installed at the other end of the bracket 22. When the cabinet door 2 is closed, the terminal switch 21 is squeezed, thereby driving the bracket 22 to rotate around the pull rod 24, so that the power supply terminal 27 at the other end of the bracket 22 extends out and contacts the cabinet port terminal 11.
[0025] Specifically, one end of the pull rod 24 is welded and fixed to the frame 210 , and a collar is installed at the other end of the pull rod 24 . The collar is sleeved on the middle part of the bracket 22 to facilitate the bracket 22 to rotate under force.
[0026] Furthermore, when the cabinet door 2 is opened, the bracket 22 is in a normal state, the end of the terminal switch 21 passes through the frame 210 and extends out, the power supply terminal 27 is located on the inner side of the frame 210, and terminal extension openings 29 are provided through the frame 210 near the terminal switch 21 and the power supply terminal 27; when the cabinet door 2 is closed, the terminal switch 21 is pressurized, driving the bracket 22 to rotate, so that the end of the power supply terminal 27 passes through the frame 210 and contacts the cabinet port terminal 11, and the terminal switch 21 retracts to the inner side of the frame 210.
[0027] Furthermore, a sleeve 25 is installed on the inner side of the frame 210 near the terminal switch 21 and the power supply terminal 27, and a spring 23 is sleeved on the outside of the sleeve 25. One end of the spring 23 is connected to the inner side of the frame 210, and the other end is connected to the outer wall of the bracket 22, so that 22 can be reset when no force is applied.
[0028] Furthermore, an opening is provided on one side of the bracket 22 close to the sleeve 25 , and one end of the sleeve 25 is slidably connected to the opening of the bracket 22 , so as to facilitate stable rotation of the bracket 22 .
[0029] Furthermore, the heating film 28 is made of conductive material and is adhered to the glass surface of the cabinet door 2 through a layer of thermally conductive adhesive. When the heating wire 26 is energized, the heating film 28 is heated, thereby achieving heating of the cabinet door 2 glass.
[0030] When the electric heated sliding glass door of the utility model is in use, first when the cabinet door 2 is in the open state, the bracket 22 maintains a normal position, at this time, the end of the terminal switch 21 penetrates the frame 210 and extends outward, while the power supply terminal 27 is located on the inner side of the frame 210 and does not contact the cabinet port terminal 11. Therefore, the heating circuit is in a disconnected state, and the heating film 28 does not work. When the user closes the cabinet door 2, the terminal switch 21 is first squeezed by the cabinet port. This squeezing force acts on the bracket 22, causing it to rotate around the fixed point of the pull rod 24. As the bracket 22 rotates, the power supply terminal 27 originally located on the inner side of the frame 210 is driven to extend outward until it contacts the cabinet port terminal 11. Once the power supply terminal 27 contacts the cabinet port terminal 11, the heating circuit is turned on. The current flows to the heating film 28 through the heating wire 26. The heating film 28 is made of conductive material and can quickly convert electrical energy into thermal energy, and evenly transfer it to the glass door through the thermal conductive glue, thereby preventing condensation on the glass surface due to temperature difference. When the user opens the cabinet door 2 again, the squeezing force on the terminal switch 21 disappears, and the elastic force of the spring 23 takes effect, pushing the bracket 22 to return to the initial state. As the bracket 22 is reset, the power supply terminal 27 is separated from the cabinet port terminal 11, the heating circuit is disconnected, and the heating film 28 stops heating.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
