[0021] See also Figure 1-Figure 5 As shown, the present invention provides a display cabinet with a novel air outlet structure, comprising a refrigeration mechanism 1, and a display cabinet 2 is installed on the upper end of the refrigeration mechanism 1; The display cabinet 2 includes a cabinet body 21, a cabinet door 22 hinged at the left end of the cabinet body 21, and two vertically placed support frames 23 arranged inside the cabinet body 21 and parallel to each other. A plurality of display tables 24 are hung on the support frames 23. An air supply mechanism 25 is arranged at the lower side of the cabinet body 21. The air supply mechanism 25 includes an evaporator 251, a cross-flow fan 257 installed on the right side of the evaporator 251, a grid-shaped air inlet 252 installed on the left side of the evaporator 251, a heat preservation cotton 254 installed on the upper side of the evaporator 251, and a water receiving box 256 installed on the lower side of the evaporator 251. A duct baffle 258 is connected to the right side of the cross-flow fan 257, and duct foam 259 is arranged in the duct baffle 258. A grid safety net 253 is arranged on the left side of the grid-shaped air inlet 252, and an evaporator upper cover 255 is arranged on the upper side of the thermal insulation cotton 254. When the refrigeration mechanism 1 is in operation, the cross-flow fan 257 is started, and the hot air in the cabinet passes through the grid safety net 253 and the grid-shaped air inlet 252 to enter the evaporator 251. After evaporation and heat exchange in the evaporator 251, the cold air is blown into the air duct through the cross-flow fan 257, and then blown to each layer of the shelf 241 through the seal of each layer inside the air duct, so as to cool down the inside of the cabinet 21. The condensed water or defrosted water on the evaporator 251 passes through the water receiving box 256 and is sent into the evaporating dish 15 by the connecting pipe 16, and evaporates through the evaporating tube in the evaporating dish 15.

[0022] The display stand 24 includes a shelf 241 and an air outlet 242 opened on the rear surface of the shelf 241. The shelf 241 is composed of two parts, a horizontal plate and a vertical plate. The air outlet 242 is opened on the side surface of the vertical plate. The horizontal plate is provided with a connecting hole for the support frame 23 to pass through. The display stand 24 can be adjusted on the support frame 23 as needed, so as to facilitate the adjustment of the display space size.

[0023] Specifically, the refrigeration mechanism 1 includes a mounting shell 11, a wheel 12 mounted on the lower surface of the mounting shell 11, a rear cover 13 arranged at the right end of the mounting shell 11, and a front cover 19 located at the left end of the mounting shell 11. A compressor 14 is installed on the right side of the lower surface of the interior of the mounting shell 11, an evaporating dish 15 is installed at the middle position of the lower surface of the interior of the mounting shell 11, a condensing fan 17 is installed on the left side of the lower surface of the interior of the mounting shell 11, a condenser 18 is installed at the left end of the lower surface of the interior of the mounting shell 11, and a connecting pipe 16 is installed on the upper surface of the evaporating dish 15. Through the connecting pipe 16, water condensed on the surface of the evaporator 251 received by the water receiving box 256 is transported into the evaporating dish 15 to treat the water.

[0024] Furthermore, magnetic strips are provided at the contact position between the cabinet door 22 and the cabinet body 21. The magnetic strips are distributed on the upper and lower sides and the rear side of the cabinet door 22. The cabinet door 22 and the cabinet body 21 are connected by a magnetic seal, which can ensure that the cabinet door 22 and the cabinet body 21 are sealed while the cabinet door 22 can be easily opened.

[0025] Specifically, the upper end of the connecting pipe 16 is installed on the lower surface of the outer side of the water receiving box 256, and a through hole for placing the connecting pipe 16 is opened under the inner surface of the water receiving box 256. The water generated by the evaporator 251 connected to the water receiving box 256 will be sent to the evaporating dish for treatment through the connecting pipe 16.

[0026] In addition, the compressor 14 and the evaporating dish 15 are connected through a first pipe, and the evaporating dish 15 and the condenser 18 are connected through a second pipe. The first pipe and the second pipe are both in a 7-shaped structure. The second pipe is located on the upper side of the first pipe, and the condenser 18, the compressor 14 and the evaporating dish 15 are connected through the pipe.

[0027] Furthermore, the wheel 12 is a universal wheel, and a brake assembly is provided on the wheel 12. The wheel 12 is made of rubber. There are four wheels 12 in total, which are installed at the four corners of the lower surface of the mounting shell 11, so that the user can open the brake assembly on the wheel 12 when needed, push the device as a whole to move according to the display needs, and close the brake assembly after moving to the appropriate position to fix the wheel 12.

[0028] Specifically, the cross-section of the grid-like air inlet 252 is in the shape of a right triangle, and the hypotenuse of the right triangle is placed on the upper left side. The inclination angle of the grid safety net 253 is consistent with the hypotenuse angle of the grid-like air inlet 252. The right side surface of the grid-like air inlet 252 fits tightly against the evaporator 251. The gas entering the evaporator 251 is filtered through the grid safety net 253 and the grid-like air inlet 252 to protect the evaporator 251 and prevent impurities in the air from entering the evaporator 251 and affecting the service life of the evaporator 251.

[0029] It is worth mentioning that a number of ventilation slots are provided on the side surface of the air duct baffle 258, and a number of ventilation slots are also provided at the corresponding position of the air duct foam 259. The two ventilation slots are of the same size and have corresponding positions. The cold air delivered by the cross-flow fan 257 enters each layer of the display stand 24 in the cabinet 21 through the ventilation slots, ensuring that the temperatures of different display stands 24 are almost the same and the cooling time is also almost the same.

[0030] Furthermore, a gap is reserved between the inner rear surface of the cabinet 21 and the display stand 24, and the gap is an air duct, in which an air duct baffle 258 and an air duct foam 259 are placed. The lower end of the air duct baffle 258 in the air duct is fixedly installed on the right side of the upper surface of the partition plate. The air duct baffle 258 cooperates with the partition plate to separate the display stand 24 from the inner lower surface and the right side surface of the cabinet 21.

[0031] Furthermore, a cavity is reserved between the inner lower surface of the cabinet 21 and the lowermost display stand 24, and an air supply mechanism 25 is installed in the cavity. A partition plate is arranged at the top of the cavity, and the right side of the partition plate is an air duct. A gap is reserved between the left side of the partition plate and the cabinet door 22, and a grid safety net 253 is installed in the gap. The reserved gap allows the grid safety net 253 to be installed at an angle. The upper end of the grid safety net 253 is fixedly connected to the left end of the partition plate, and the lower end of the grid safety net 253 is fixedly connected to the left side of the inner lower surface of the cabinet 21, ensuring that the grid safety net 253 can intercept and filter all wind entering the evaporator 251 once, and then intercept and filter it for a second time through the grid-shaped air inlet 252. The secondary filtration of the grid safety net 253 and the grid-shaped air inlet 252 can effectively extend the service life of the evaporator 251.

[0032] It is worth mentioning that the structures and working principles of the wheel 12, compressor 14, evaporating dish 15, condensing fan 17, condenser 18, evaporator 251, and cross-flow fan 257 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0033] The present invention is applicable to existing display cabinets. Due to the high number of layers, the evaporator and the fan are usually installed on the north side of the display cabinet. In order not to affect the display effect, multiple smaller centrifugal fans are used. Although the display area is increased, the fan is small, the air volume is also small, the refrigeration time is prolonged, and the overall refrigeration effect is reduced. Therefore, the display cabinet of the present invention is invented; When in use, first open the brake assembly on the wheel 12 so that the wheel 12 can move freely, then push the display cabinet 2 and the refrigeration mechanism 1 to move to a suitable position as a whole, then close the brake assembly, and then open the cabinet door 22, and adjust the height of the display table 24 on the support frame 23 in the cabinet body 21 as needed. After adjustment, fix the position of the display table 24, place the exhibits, close the cabinet door 22, and start the refrigeration mechanism 1 to cool the cabinet body 21; When the refrigeration mechanism 1 is in operation, the cross-flow fan 257 is started first, and the hot air in the cabinet passes through the grid safety net 253 and the grid-shaped air inlet 252 to enter the evaporator 251. After evaporation and heat exchange in the evaporator 251, the cold air is blown into the air duct through the cross-flow fan 257, and then blown to each layer of the shelf 241 through the seal of each layer inside the air duct, so as to cool down the inside of the cabinet 21. The condensed water or defrosted water on the evaporator 251 is sent to the inside of the evaporating dish 15 through the connecting pipe 16 after passing through the water receiving box 256, and evaporated through the evaporation tube in the evaporating dish 15. The condenser 18, the condensing fan 17 and the compressor 14 in the housing 11 are installed to cooperate with the evaporator 251 to realize the function of evaporation and cooling. The present invention solves the problem of small display area of ​​the traditional display cabinet 2 by integrating all the refrigeration components on the lower side of the display cabinet 2, and improves the problems of uneven air supply in the existing display cabinet 2, large temperature difference of different inverted shelves 241, and asynchronous cooling time.
