Still further, the evaporation fan is an axial flow fan and is fixed on the outer side of the evaporation air duct cover plate through screws.

Compared with the prior art, the utility model has the following advantages:

1) the evaporation fan is arranged on the air inlet side of the evaporator, and the air cooling circulation layout of air blowing is adopted, so that the existing redundant space in the refrigerating chamber of the beverage pre-conditioner can be reasonably utilized, the size of the box body does not need to be increased, and the air cooling circulation structure layout is compact;

2) compared with a direct cooling mode, the air cooling mode strengthens the heat exchange efficiency, the pull-down speed of the temperature in the box is accelerated, and the temperature in the box is more uniform;

3) because the circulating air duct is wide at the bottom and narrow at the top, the air pressure is increased before air is exhausted from the upper air outlet, the accelerated circulation of air is realized, and the air cooling effect is greatly improved.

Detailed Description

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In this document, the directions used to explain the structure and/or actions of the various parts of the disclosed embodiments, such as "upper", "lower", etc., are not absolute, but relative. These representations are suitable when the various parts of the disclosed embodiments are located in the positions shown in the figures, and if the position or frame of reference of the disclosed embodiments is changed, they are also changed according to the change in the position or frame of reference of the disclosed embodiments.

As shown in fig. 1 and 2, the air-cooled circulation structure for a beverage pre-conditioner according to an embodiment of the present invention includes an evaporator 1, an evaporation air duct cover plate 3 and an evaporation fan 5, wherein the evaporation air duct cover plate 3 is configured to be fixed on the inner container rear wall 113 of the refrigerating chamber 103 of the beverage pre-conditioner 100, so as to form a circulation air duct 33 with a wide bottom and a narrow top between the evaporation air duct cover plate 3 and the inner container rear wall 113, the evaporation air duct cover plate 3 is provided with an upper air outlet 30 and a lower air return inlet 35, the evaporator 1 is located in the circulation air duct 33, and the evaporation fan 5 is installed outside the evaporation air duct cover plate 3 and is arranged corresponding to the lower air return inlet 35.

As shown in fig. 1 and fig. 2, the evaporation duct cover 3 includes an upper cover section 31 spaced from the liner rear wall 113 by a first distance and a lower cover section 32 spaced from the liner rear wall 113 by a second distance, where the first distance is smaller than the second distance, the circulation duct 33 has a narrow duct section 331 and a wide duct section 332, specifically, the narrow duct section 331 is located at an upper portion corresponding to the upper cover section 31, and the wide duct section 332 is located at a lower portion corresponding to the lower cover section 32.
