Description

Technical Field

[0002] Refrigerated display cabinets are refrigerated facilities in food markets, grocery stores, supermarkets and other sales links, used to display and sell food and other commodities that need to be refrigerated. It has become an important part of the cold chain construction and plays an important role in ensuring food quality and safety;

[0003] Common horizontal refrigerated display cabinets on the market are mostly air-cooled or direct-cooled. Directly using an air-cooled refrigeration system to cool down the food will result in uneven cooling, with the upper layer cooling down quickly and the lower layer cooling down slowly, or even failing to meet the temperature requirements. In addition, a fast wind speed will cause excessive water loss in the food, affecting the appearance and taste of the food. Directly using a direct-cooled refrigeration system to cool down the food will still result in uneven cooling of the food, with the upper layer cooling down slowly and the lower layer cooling down quickly, or even failing to meet the temperature requirements. When the evaporation temperature is too low, ice will easily form on the padding plate, and it is not easy to clean. Therefore, the above two refrigeration methods will result in uneven food temperatures, and in severe cases, the temperature requirements of the food will not be met. For this reason, a horizontal air direct-cooled duct refrigerated display cabinet is proposed. Utility Model Content

DETAILED DESCRIPTION

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 6 As shown, the embodiment of the utility model provides a horizontal type direct air cooling duct refrigerated display cabinet, comprising an air cooling assembly 1, the air cooling assembly 1 comprising a refrigeration box 11, an evaporator 12, an evaporating fan 13, an air duct orifice plate 14, an air cooling duct cavity 15, a wind shield 16, a supporting foot plate 17, a cushion plate 18, an air duct plate 19 and an air cooling duct cavity 20;

[0030] An evaporator 12 is installed on one side of the inner bottom wall of the refrigeration box 11, an evaporation fan 13 is installed on the side of the middle of the inner bottom wall of the refrigeration box 11 close to the evaporator 12, an air duct plate 14 is fixedly connected to the upper part of the inner side wall of the refrigeration box 11 close to the evaporator 12, an air cooling air duct cavity 15 is provided between the side of the inner side wall of the refrigeration box 11 close to the evaporator 12 and the air duct plate 14, a wind shield 16 is fixedly connected to the upper part of the inner side wall of the refrigeration box 11 away from the evaporator 12, and the wind shield 16 and the air duct plate 14 are connected to each other. 4 are welded with supporting foot plates 17 at the bottom, and pad plates 18 are attached to the upper surfaces of the two supporting foot plates 17. An air duct plate 19 is fixedly connected to the lower part of the inner wall of the refrigeration box 11 near the pad plate 18. The lower surface of the air duct plate 19 is fixedly connected to the upper surface of the evaporator 12 on one side near the air duct orifice plate 14 through two supporting strips 21. A direct cooling air duct cavity 20 is provided between the air duct plate 19 and the pad plate 18, and a return air channel cavity 22 is provided between the air duct plate 19 and the inner bottom wall of the refrigeration box 11.

[0031] In one embodiment, specifically: the air inlet ends of the air-cooling air duct cavity 15 and the air-direct cooling air duct cavity 20 are both connected to the air outlet ends of the return air duct cavity 22, and the air inlet ends of the air-cooling air duct cavity 15 and the air-direct cooling air duct cavity 20 are both connected to the air outlet ends of the return air duct cavity 22, thereby effectively reducing the amount of cold air entering the display cabinet through the air-cooling air duct cavity 15, and then reducing the cold air speed. By reducing the wind speed, the cold air blown onto the food takes away less moisture from the surface of the food, thereby effectively reducing the dry loss of food.

[0032] In one embodiment, specifically: the air outlet end of the direct cooling air duct cavity 20 is connected to the air inlet end of the return air duct cavity 22, and the air outlet end of the direct cooling air duct cavity 20 and the air inlet end of the return air duct cavity 22 are connected, so that the air after heat exchange in the direct cooling air duct cavity 20 can enter the return air duct cavity 22 for circulation.

[0033] In one embodiment, specifically: a front baffle 23 is fixedly connected to one side of the upper surface of the cushion plate 18 close to the wind shield 16, and the front baffle 23 on the cushion plate 18 blocks the cold air, thereby increasing the residence time of the cold air and preventing the cold air from directly entering the return air port 24.

[0034] In one embodiment, specifically: a return air outlet 24 is provided on the upper surface of the cushion plate 18 near the front baffle 23 and the wind shield 16, a filter screen 25 is slidably connected to the inner wall of the return air outlet 24, a limit frame 35 is fixedly connected to the outer side of the upper surface of the filter screen 25, and the lower surface of the limit frame 35 is fittedly connected to the outer side of the return air outlet 24 near the upper surface of the cushion plate 18, so that the filter screen 25 arranged in the return air outlet 24 prevents food and other debris from falling into the return air channel cavity 22.

[0035] In one embodiment, specifically: a support plate 26 is fixedly connected to one side of the upper surface of the refrigeration box 11 close to the air duct orifice plate 14, and the upper surface of the air duct orifice plate 14 is fixedly connected to one side of the lower surface of the support plate 26. Through the connection between the air duct orifice plate 14 and the support plate 26, the firmness of the air duct orifice plate 14 is increased.

[0036] In one embodiment, specifically: a top plate 27 is fixedly connected to a side of the upper surface of the refrigeration box 11 close to the windshield 16, an upper track 28 is provided on a side of the lower surface of the top plate 27 away from the windshield 16, a lower guide rail 29 is provided on one side of the upper surface of the support plate 26, a plurality of glass doors 30 are slidably connected to the sides of the upper and lower guide rails 28 and 29 that are close to each other, and handles 31 are fixedly connected to the sides of the upper surfaces of the two glass doors 30 that are away from each other, so that the glass doors 30 can be opened conveniently by means of the upper track 28 and the lower guide rail 29, so as to take and put food and other items.

[0037] In one embodiment, specifically: a plurality of fans 32 are provided on a side of the inner wall of the evaporator fan 13 away from the evaporator 12, and wind is blown toward the evaporator 12 simultaneously by the plurality of fans 32 in the evaporator fan 13, so that the wind force blowing toward the evaporator 12 is more uniform.

[0038] In one embodiment, specifically: a plurality of cooling air slots 33 are evenly opened on one side of the evaporator 12, so that the wind blown by the evaporation fan 13 can pass through the inside of the evaporator 12 to cool down through the plurality of cooling air slots 33 on the evaporator 12.

[0039] In one embodiment, specifically: both sides of the lower surface of the refrigeration box 11 are fixedly connected with support legs 34, and the support of the refrigeration box 11 by the support legs 34 increases the stability of the refrigerated display cabinet.

[0040] When the utility model is working: first, when food and other commodities that need to be refrigerated are placed inside the display cabinet, the evaporative fan 13 is started to make the air inside the refrigerating box 11 flow. The operation of the evaporative fan 13 will make the cold energy generated by the evaporator 12 be blown to the air-cooling duct cavity 15 and the air-direct cooling duct cavity 20. For the air-cooling duct cavity 15, the cold air will be blown to the upper food through the holes on the air duct orifice plate 14 to ensure its cooling speed. For the air-direct cooling duct cavity 20, the cold air will first be blown to the metal pad plate 18 to reduce the temperature of the pad plate 18, and then the pad plate 18 will transfer the cold energy to the food on the lower layer. This method can not only ensure the cooling speed of the food on the lower layer, but also avoid excessive water loss rate of the food due to excessive wind speed. When the cold air blows through the food, the temperature will rise, and this part of the air will pass through the return air on the pad plate 18. The air outlet 24 returns to the return air duct cavity 22, and passes through the filter 25 provided in the return air outlet 24, thereby preventing food and other debris from falling into the return air duct cavity 22 and affecting the air circulation. At the same time, the air in the direct cooling air duct cavity 20 also returns to the return air duct cavity 22, and the air in the return air duct cavity 22 is blown to the evaporator 12 by the evaporating fan 13 again. After being cooled again by the evaporator 12, it will be blown to the cooling air duct cavity 15 and the direct cooling air duct cavity 20. In this way, the food inside the display cabinet is cooled and refrigerated. The two air duct systems of the cooling air duct cavity 15 and the direct cooling air duct cavity 20 can not only ensure the uniform cooling of the upper and lower layers of food, but also control the water loss rate of the food, so as to meet the temperature requirements of the food. At the same time, the provision of the metal pad plate 18 avoids the icing problem of the direct cooling refrigeration system and makes cleaning easier.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
