Technical Field
[0001] This invention relates to the field of horizontal air-cooled freezer technology, specifically a horizontal air-cooled freezer. Background Technology
[0002] A horizontal air-cooled freezer is a type of freezer that uses air cooling. Its working principle is to use an electric fan to bring refrigerant into the cooling chamber, and then use natural fans to dissipate heat to lower the temperature. The main advantages of air-cooled freezers are that they have a better ventilation system, smooth airflow, stable cooling effect, and are not affected by ambient temperature and humidity. At the same time, they can maintain the quality of air circulation inside the cabinet, making the door seals and electrical control components more stable and easier to maintain. The storage method for horizontal air-cooled freezers is generally to place the goods directly inside the freezer. After a period of refrigeration, the goods tend to solidify on the inner wall of the freezer. It is very difficult for operators to remove the goods that have solidified on the inner wall of the freezer. Sometimes, it is even necessary to turn off the freezer and wait for the ice on the surface of the goods to melt before they can be taken out. Summary of the Invention

[0006] Furthermore, the end of the column passes through the central frame and extends to the outer end of the central frame. There are two rectangular frames, which are symmetrically arranged with the central frame as the center. There are also two partition frames, which are symmetrically arranged with the rectangular frames as the center. The end of the grooved plate near the moving block contacts the inner wall of the central frame.
[0007] Furthermore, the chute is located at the end of the grooved plate away from the triangular block, the push plate is located below the divider, the pressing plate extends to the bottom of the handle at the end away from the push plate, and the end of the triangular block near the disc is flat and in contact with the inner wall of the grooved plate.

When the pull plate is pulled upwards, it will pull the center of the tripod upwards. The tripod uses the through holes to push the support plate to move. When the support plate moves, it can push the two sets of through-hole plates to move closer to each other. When it is necessary to take out the goods, the through-hole plates moving closer to each other can move the goods towards the center of the freezer, improving the convenience of retrieving the goods from the outside.
[0016] When the placement plate of this invention moves, it pushes the synchronous plate to slide inside the slide groove through the connecting plate. When the synchronous plate moves, it pushes the spatula to move along the inner wall of the freezer. When the spatula moves, it pushes the goods on the inner wall of the freezer to move towards the center of the freezer, thus preventing the goods from condensing on the inner wall of the freezer and affecting the convenience of picking up the goods.
