The number of the limiting cooperation parts 30 is equal to the number of the limiting parts 20 and they correspond to each other one by one.
[0077] Optionally, the number of the screws 70 is multiple, and the multiple screws 70 are arranged oppositely along the width direction of the air duct cover plate 11 to ensure the reliability of the connection.
[0078] The assembly process of the cover plate assembly 10 and the inner container 50 is as follows: First, the first limiting part 201 is matched with the first limiting cooperation part 301, that is, the limiting protrusion 21 is inserted into the limiting groove 31, so that the air duct cover plate 11 is connected to the first inner container 51, and the air duct cover plate 11 can move downward relative to the first inner container 51 to press the second sub-seal 412. Then, the second limiting part 202 is matched with the second limiting cooperation part 302, that is, the evaporator cover plate 12, the air duct cover plate 11 and the inner container 50 are connected by the screw 70, so that the evaporator cover plate 12 has a tendency to move downward to press the fourth sub-seal 422. At the same time, when the screw 70 is connected, a horizontal pressing component force is generated to press the first sub-seal 411 and the third sub-seal 421. Thus, when the cover plate assembly 10 is connected to the inner container 50, the seal 40 can be pressed to ensure the airtightness of the refrigeration equipment.
