Compared with the refrigerator that can be restocked from the rear, the efficiency of the air curtain cabinet that can only be replenished from the front is not high. A shelf can be pulled out like a drawer, but the bottom baffle for energy saving restricts the pull-out of the drawer shelf, which makes it more difficult to use replenishment. In general air curtain cabinets, the unsold products must be taken out when replenishing, then the new products are added to the shelf, and the old products that have just been removed have not been sold and then refilled on the row surface, reaching the first-in first-out Commodity management principles, but this work is very time-consuming and laborious. In order to save labor and labor, the general air curtain cabinet will change the shelf to a drawable type like a drawer, which is convenient for pulling out when replenishing, and replenishing fresh goods behind the old ones, so that the first-in first-out rule can be easily realized . In addition, in order to save energy, the general air curtain cabinet will add a baffle in front of the return air inlet to reduce the amount of external air intrusion, and also reduce the airflow overflowing the air curtain. The above two energy-saving and energy-saving designs are used in the bottom shelf at the same time, the functions are conflicting. When the drawer shelf is pulled out, it will hit the return air baffle and cannot be drawn out, and remove the return air baffle , The drawer shelf is pulled out, and the energy-saving function is lost, so the bottom shelf is generally fixed and cannot be drawn out, and the bottom position is low, it is more laborious to replenish itself, and it is even more necessary to supplement the goods inside the bottom layer Trouble, you can't touch the goods inside without squatting, sitting, or lying down.
