DETAILED DESCRIPTION
[0025] The specific implementation of an air curtain cabinet with a foldable glass door provided by the utility model is further described in conjunction with the accompanying drawings and embodiments.
[0026] like Figure 1 As shown, an air curtain cabinet with a folding glass door comprises a foam box 1 and a folding glass door 2. The foam box 1 is a rectangular cavity structure with an opening at the front end, and a door frame is installed at the opening, and the door frame comprises a top frame, a bottom frame and two left and right side frames; preferably, a slide rail is provided on the opposite side of the top frame and the bottom frame; the top and bottom of the folding glass door 2 are provided with connecting pieces, and the folding glass door 2 is slidably connected with the upper and lower slide rails of the door frame through the connecting pieces to realize the opening or closing of the folding glass door 2.
[0027] like Figure 2 As shown, the inner cavity of the foam box 1 is provided with an inner liner, and the left and right sides of the inner liner are fixed to the left and right inner walls of the foam box 1. The inner liner includes a leeward plate 12, a top wind plate 13 and a bottom plate 14;
[0028] Preferably, the leeward plate 12 is arranged in front of the rear wall of the foaming box body 1 and the lower end of the leeward plate 12 is inclined forward; the top wind plate 13 is arranged in parallel below the top wall of the foaming box body 1, and the bottom plate 14 is arranged horizontally above the bottom wall of the foaming box body 1; and a partition 15 is also horizontally arranged between the bottom plate 14 and the bottom wall of the foaming box body 1, and the space between the lower part of the partition 15 and the bottom wall of the foaming box body 1 constitutes a press room for placing the refrigeration equipment; preferably, a ventilation cover 3 is arranged at the front end of the press room, and the ventilation cover 3 is installed at the lower part of the folding glass door 2, corresponding to the position of the condenser 4, and a plurality of heat dissipation ports are evenly distributed on the surface of the ventilation cover 3, which can effectively improve the heat dissipation effect of the condenser 4.
[0029] Preferably, a honeycomb box 131 is provided on a side of the top wind plate 13 away from the leeward plate 12 , and an air return port 141 is provided on the bottom plate 14 at a position corresponding to the position directly below the honeycomb box 131 .
[0030] It is worth mentioning that a longitudinal air duct is formed between the leeward plate 12 and the rear wall of the foam box 1; a transverse air duct is formed between the top air plate 13 and the top wall of the foam box 1; a return air duct is formed between the bottom plate 14 and the partition plate 15; the top of the longitudinal air duct is connected with the rear end of the transverse air duct; the bottom of the longitudinal air duct is connected with the rear end of the return air duct; thereby forming a circulating air duct structure.
[0031] Preferably, the inner tank is provided with a plurality of shelves 9 at equal intervals from top to bottom; the leeward plate 12 is provided with a plurality of air outlets in a horizontal direction corresponding to the position below each shelf 9. When in use, a part of the cold air directly enters the inner tank cavity through the air outlets on the leeward plate 12, so that the cooling effect of the inner tank area is more uniform; the other part passes through the longitudinal air duct upward into the transverse air duct, and then flows downward from the honeycomb box 131 to form a stable cold air curtain, and then passes through the return air port 141 into the return air duct at the bottom, thereby realizing circulating air supply.
[0032] It is also preferred that a controller, a condenser 4, a condensing fan 5 and a compressor 6 are arranged in the compressor room; wherein the condenser 4 is arranged on a side close to the ventilation cover plate 3; the condensing fan 5 is arranged between the condenser 4 and the compressor 6, on a side close to the condenser 4; an evaporator 7 is arranged in the longitudinal air duct, at a position close to the rear end of the bottom plate 14; an evaporating fan 8 is arranged in the return air duct, on a side close to the evaporator 7; the evaporator 7 is connected to the condenser 4 through a capillary tube; the evaporator 7 is connected to the compressor 6 through a return air pipe;
[0033] Further preferably, a temperature controller 11 is installed at the front end of the foaming box 1 and above the folding glass door 2 to display the temperature inside the air curtain cabinet.
[0034] It is worth noting here that the temperature controller 11, the condenser 4, the condensing fan 5, the compressor 6, the evaporator 7, and the evaporating fan 8 are all controlled by the controller.
[0035] like Figure 3 As shown, when the folding glass door 2 is fully opened, it can be folded on the left and right sides of the door frame of the foaming box 1 without occupying the aisle space; when the folding glass door 2 is fully closed, the material of the transparent glass will not affect the display area and effect of the products in the cabinet.
[0036] Compared with the traditional fully open air curtain cabinet, the utility model can close the door when the passenger flow is low. At this time, the cold air in the cabinet is completely sealed, which can effectively avoid the energy loss caused by the heat exchange between the inside and outside of the cabinet.
