Description

Technical Field

[0001] This utility model relates to the field of refrigerated display cabinets, and particularly to a refrigerated display cabinet with an evaporator mounted on top. Background Technology

[0002] In traditional food refrigerated display case designs, the evaporator is usually located at the bottom of the cabinet. Its main function is to utilize the downward sinking effect of cold air formed at this location to promote the natural downward flow of cold air and its diffusion throughout the entire cabinet space, thereby achieving effective cooling of the stored food. This bottom setting was a key means of achieving basic temperature control in early technologies.

[0003] However, this bottom-mounted evaporator design has significant drawbacks: First, food residue or juices easily fall into the evaporator coils at the bottom, breeding bacteria and being difficult to clean thoroughly, posing a hygiene risk. Additionally, the increased thickness at the bottom to accommodate the evaporator and fan forces food to be placed at a higher position, increasing the customer's downward viewing angle and diminishing the display's intuitiveness and appeal. Second, while the fixed legs commonly installed at the bottom of the cabinet provide support, they severely restrict the flexible movement of the equipment, making relocation time-consuming and laborious.

[0004] Therefore, it is necessary to propose a refrigerated display case on top of the evaporator to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a refrigerated display cabinet with an evaporator on top, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The refrigerated display cabinet with evaporator is provided, including a cabinet body, a tray rack set in the inner cavity of the cabinet body and support legs set at the four corners of the bottom of the cabinet body. The evaporator is set at the upper inner side of the cabinet body, and the bottom and left and right ends of the evaporator are provided with air outlets.

[0008] An auxiliary frame is provided on the side of the cabinet, and a lifting rod is vertically and movably connected to the auxiliary frame. A caster wheel is provided at the bottom of the lifting rod. A drive assembly for driving the lifting rod to rise and fall is provided at the upper end of the auxiliary frame. The drive assembly includes a groove provided at the upper end of the auxiliary frame. A flip frame is rotatably provided at the upper end of the inner side of the groove. A roller is rotatably provided at the lower side of the flip frame. A lifting plate corresponding to the roller is provided at the upper end of the lifting rod. When the flip frame flips, it can drive the roller to squeeze the lifting plate downward.

[0009] Preferably, the auxiliary frames are symmetrically arranged on both sides of the cabinet, each auxiliary frame is provided with a pair of lifting rods, and the lifting plate is fixed to the top of the pair of lifting rods.

[0010] Preferably, the auxiliary frame is provided with a through hole corresponding to the lifting rod, and the lifting rod is vertically and movably connected to the inside of the through hole.

[0015] Beneficial effects

[0016] Compared with the prior art, this utility model provides a refrigerated display case with an evaporator on top, which has the following features:

[0017] Beneficial effects:

[0018] 1. This evaporator is mounted on top of a refrigerated display case. After moving the evaporator to the top of the food in the cabinet, its air inlet and outlet are located at the top, effectively eliminating the hygiene risks of food residue falling into and contaminating the evaporator. This significantly improves the ease of cleaning and hygiene level of the equipment. At the same time, the bottom chassis structure of the cabinet can be thinned, allowing the displayed food to be placed at a lower position, optimizing the customer's view and enhancing the product display effect. In addition, compared to the bottom evaporator, the top design can add air outlets on both the left and right sides, promoting more uniform air circulation inside the cabinet, greatly reducing temperature differences, thereby improving the overall cooling performance and food preservation effect.

[0019] 2. The evaporator features a refrigerated display cabinet on top. With the help of an auxiliary frame and adjustable casters, the cabinet can be raised and lowered via a flip-up frame. When it needs to be moved, the casters can be lowered to lift the cabinet off the ground, while the horizontally flipped handles can act as sturdy push-pull handles. The operation is convenient and effortless. After the move is completed, the casters can be raised and the flip-up frame can be hidden on the side of the cabinet. This not only ensures the stability of the equipment when it is placed, but also does not occupy any external space. The design is ingenious and practical. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1-6 As shown, the refrigerated display cabinet with evaporator is provided, including cabinet body 1, tray rack 4 set in the inner cavity of cabinet body 1 and support legs 3 set at the four corners of the bottom of cabinet body 1. Evaporator 6 is set at the upper inner side of cabinet body 1, and air outlets 7 are set at the bottom and both sides of evaporator 6.

[0029] Auxiliary frames 2 are provided on the sides of cabinet 1, symmetrically arranged on both sides of cabinet 1. Lifting rods 8 are vertically and movably connected to the auxiliary frames 2. Specifically, the auxiliary frames 2 have through holes 15 corresponding to the lifting rods 8, and the lifting rods 8 are vertically and movably connected to the inside of the through holes 15. Each auxiliary frame 2 has a pair of lifting rods 8. Universal wheels 9 are provided at the bottom of the lifting rods 8. A drive assembly for driving the lifting rods 8 to rise and fall is provided at the upper end of the auxiliary frames 2. The drive assembly includes a groove 12 located at the upper end of the auxiliary frame 2, and a tilting frame 10 is rotatably mounted on the upper end of the inner side of the groove 12. Specifically, a rotating shaft 18 is fixed at the lower end of the tilting frame 10. The tilting frame 10 is rotatably connected to the groove 12 through the rotating shaft 18. A roller 17 is rotatably provided on the lower side of the tilting frame 10. Specifically, a roller frame 16 is provided on the lower side of the tilting frame 10. The roller 17 is rotatably provided on the roller frame 16. A lifting plate 13 corresponding to the roller 17 is provided at the upper end of the lifting rod 8. Specifically, the lifting plate 13 is fixed to the top of the pair of lifting rods 8. When the tilting frame 10 is tilted, the roller 17 can be driven to squeeze the lifting plate 13 downward. A handrail 11 is provided at the upper end of the tilting frame 10.

[0030] To facilitate the reset and rise of the caster wheel 9, an elastic element 14 is provided between the bottom of the lifting plate 13 and the bottom of the inner side of the groove 12. The elastic element 14 is preferably a spring, and the spring is sleeved on the outer side of the upper end of the lifting rod 8 to increase its stability.

[0031] To facilitate the collection and cleaning of food scraps, a collection trough 5 with an open top is placed on the bottom inside the cabinet 1. The collection trough 5 can also be used to place food trays.

[0032] It should be noted that this utility model is a refrigerated display cabinet with the evaporator on top. When in use, after the evaporator 6 is moved to the top of the food in the cabinet 1, its air inlet and outlet are located at the top, which effectively eliminates the hygiene hazard of food residue falling into and contaminating the evaporator 6, and significantly improves the ease of cleaning and hygiene level of the equipment. At the same time, the bottom chassis structure of the cabinet 1 is thinned, allowing the displayed food to be placed at a lower position, optimizing the customer's view and enhancing the product display effect.
