The baffle plate 31' corresponds to at least one return air hole above the evaporator 80, and at least one return air hole The air of the above-mentioned return air is made to flow toward the evaporator 80 , and circulates from the upper part of the evaporator 80 to the lower part of the evaporator 80 . The top of the evaporator 80 is close to the first cover plate 31 , and the bottom of the evaporator 80 is close to the second side wall 232 of the step portion 23 .

In this embodiment, since the baffle 31' is located at the upper part of the evaporator chamber, and the baffle 31' substantially divides the evaporation chamber into an upper space and a lower space, and the upper space is used as the third return air duct, The lower space serves as a storage space for the evaporator 80, and the upper space and the lower space communicate with each other through a plurality of air return holes on the baffle plate 31'.

The air circulation in the horizontal freezer 600 includes outlet air and return air. The evaporator fan unit 50 starts to work, sucks in the air on one side of the evaporator 80, and sends the above air from the other side of the evaporator fan unit 50, from the second air duct. Enter into the first air outlet, and enter the inner tank 20 through multiple groups of first air outlets 611 respectively; the air in the inner tank 20 enters from the first air return port 621, the second air return port 622 and the third air return port 624 respectively.
