Abstract
The utility model relates to a top-bottom ventilating refrigerating structure for sandwich basin, which belongs to the refrigerating technology of the sandwich basin, making the cooling temperature of the article in the sandwich basin uniform and the cooling rate fast. Therefore, an evaporator 1 and a forced convection blower are arranged at the rear side lower part of the heat insulation inner chamber of a container, the external side of the blower is provided with a wind shell whose bottom is provided with an air inlet, and the inner side of the wind shell with thin upward gradually is provided with a set of air outlets. The periphery of the sandwich basin is fixedly provided with a return air hood disc whose front side is provided with a set of air outlets, and the return air hood disc and the upper part of the wind shell are form a closed chamber. Thereby, a closed recirculated air system which simultaneously passes through the top and the bottom of the sandwich basin is formed.
Description
Technical field
The utility model relates to sandwich basin refrigeration technology field, particularly a kind of sandwich basin refrigeration structure that ventilates up and down.
Background technology
Existing sandwich basin cooling structure mainly contains three kinds: a kind of is direct-cooled sandwich basin refrigeration structure, and a kind of is the direct-cooled attached blower fan forced convertion formula sandwich basin refrigeration structure that helps, and another kind is air-cooled sandwich basin refrigeration structure.
Direct-cooled sandwich basin refrigeration structure is at refrigeration casing top drilling, the sandwich basin places refrigeration casing top drilling place, and the sandwich basin bottom part sinks in the refrigeration casing, and the heat absorption of boxboard back evaporation coil is lowered the temperature to article in the case (comprising the sandwich basin bottom part) in relying on.Its major defect is: (1) causes interior article (the comprising the sandwich basin bottom part) cooling rate of case slow because the interior article heat exchanger effectiveness of directly cooling evaporator and case is low; (2) because the sandwich basin places refrigeration casing top, because the sinking of cold air causes the temperature inside the box inhomogeneous, the cooling-down effect of sandwich basin is undesirable; (3) owing to have only the sandwich basin bottom part to sink in the refrigeration casing, basin inner bottom part article are cooled off, and basin internal upper part article cooling-down effect is relatively poor.
Direct-cooled attached blower fan forced convertion formula sandwich basin refrigeration structure and the direct-cooled sandwich basin refrigeration structure of helping is basic identical, blower fan just is installed to Forced Air Convection in the case in case, it has overcome the inhomogeneous of the former the temperature inside the box, but still has other shortcoming of direct-cooled sandwich basin refrigeration structure.
Air-cooled sandwich basin refrigeration structure is to adopt finned evaporator and be equipped with the forced convertion blower fan to be installed in the casing, forming independently ducting system lowers the temperature to the sandwich basin bottom part, its major defect is to be subjected to structural limitations, can't realize that top, bottom article freeze simultaneously in the sandwich basin, cause in the basin article non-uniform temperature of catching a cold, the temperature difference is bigger, and the part objects cooling rate is slower.
Summary of the invention
The technical problems to be solved in the utility model is: make in the sandwich basin article temperature of catching a cold even, and cooling rate is very fast.
The technical solution that the utility model proposed is such: a kind of sandwich basin refrigeration structure that ventilates up and down, comprise casing 10, refrigeration unit 1, evaporimeter 2, forced convertion blower fan 3, sandwich basin 8, casing 10 is provided with heat insulation inner chamber 11, sandwich basin 8 is seated in casing 10 tops by bracing frame 5, these sandwich basin 8 tops are provided with top cover 6, refrigeration unit 1 is located at heat insulation inner chamber 11 outsides of casing 10 bottoms, described casing 10 heat insulation inner chambers 11 rear side middle and lower parts are provided with evaporimeter 2 and forced convertion blower fan 3, its outside is provided with the crust of weathering 4, these crust of weathering 4 bottoms are provided with air inlet 14, and upwards the gradually thin crust of weathering 4 upper inner have one group of air outlet 12; Described sandwich basin 8 peripheries are fixed with return air cover dish 9, and these return air cover dish 9 front sides are provided with one group of air outlet 13, and described return air cover dish 9 forms an enclosed cavity 7 with the crust of weathering 4 tops, top cover 6.
The air of heat insulation inner chamber 11 enters evaporimeter 2 coolings from air inlet 14, through 3 suctions of forced convertion blower fan, enter in the enclosed cavity 7 by the vertical air outlet 12 of the crust of weathering 4 tops, one row, sandwich basin and interior food thereof are evenly cooled off, then, flow in the heat insulation cavity 11 from the vertical air outlet 13 of return air cover dish 9 front sides one row, form the distinguished and admirable system of a closed circulation.
Casing 10, the crust of weathering 4, top cover 6, return air cover dish 9 and evaporimeter 2, forced convertion blower fan 3 are formed a ducting system.
Compared with prior art, the utlity model has following beneficial effect:
(1) because the sandwich basin all has cold wind to pass through up and down, the article cooling rate is even in the sandwich basin.
(2) because the sandwich basin forms the cold air circulating system of independent sealing up and down, thereby all article cooling rates are fast in the sandwich basin.
The utility model is specially adapted to various salads, Piza etc. and is equipped with in the refrigeration or reach in freezer of sandwich basin.
