Technical Field
[0001] This utility model relates to the field of freezer technology, specifically a frost-free display freezer. Background Technology
[0002] In the commercial retail sector, especially the food retail industry, display freezers are crucial equipment for storing and displaying frozen foods. Their performance and energy consumption directly affect the operating costs of businesses and the shopping experience of consumers. Currently, there are various types of display freezers on the market. Among them, frost-free air-cooled display freezers are widely used because they effectively avoid frost formation, reduce manual defrosting costs, and ensure that food is stored in a good frozen environment.
[0003] Chinese patented invention CN214855694U discloses a frost-free, air-cooled freezer display cabinet, comprising a cabinet body and a refrigeration compressor unit mounted on the cabinet body. The cabinet body contains a freezer cavity. The refrigeration compressor unit includes a compressor, a condenser, and an evaporator. A fan connected to the evaporator is installed at the top of the freezer cavity, blowing cold air into the freezer cavity. A door frame is provided at the opening of the freezer cavity, and a glass door is hinged to the door frame. Flipping the glass door opens or closes the freezer cavity. A mounting bracket is vertically mounted on the inner wall of the freezer cavity, with several threaded positioning holes along the vertical direction. At least one slide rail is fixed to the mounting bracket through the threaded positioning holes. At least one shelf is provided inside the freezer cavity, slidably inserted into the slide rail. By adopting the above solution, it can achieve frozen storage of frozen food and also has an excellent display effect.
[0004] However, the device still has some problems. In actual use, it only uses a single hinged glass door as the opening method. Although this design makes it convenient for merchants to load and unload goods, it exposes energy consumption problems when customers are selecting goods. When customers are selecting goods, they can only open the glass door, and the opening and closing of the door will inevitably release a large amount of cold air into the outside environment. Since display freezers are usually placed in commercial places with high customer traffic, the frequency of customers opening and closing the door is extremely high. This frequent leakage of cold air makes the freezer need to constantly replenish cold energy to maintain the internal low temperature environment, which leads to a surge in energy consumption. Therefore, we propose a frost-free display freezer to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a frost-free display freezer, which has the following beneficial effects:
[0017] This invention allows items inside a cabinet to be placed on a shelf when the door is closed. The shelf is made of transparent material, making it easy to display the items inside. To retrieve an item, the user grasps the U-shaped handle and presses the push rod. The push rod moves a connecting plate via a corresponding connecting rod. During this movement, the connecting plate stretches a second spring. Simultaneously, the connecting plate moves a square rod via a hinge rod. The square rod moves a limiting ring, which stretches a first spring, causing the square rod to separate from its corresponding square groove. Pulling the U-shaped handle then moves the corresponding drawer. The drawer causes a slider to slide on a guide rod, removing the obstruction of the rectangular hole and allowing items to be retrieved from the shelf. This avoids energy waste caused by large opening and closing of the door. Attached Figure Description
