[0104] Optionally, the top plate 12 includes a main board 121 and a mounting plate 122 , the main board 121 is connected to the connecting plate 15 and extends toward the cabinet door 30 , the mounting plate 122 is connected to a side of the main board 121 facing the bottom plate 11 , and is used to connect to the first sealing member 40 .

[0105] By arranging the top plate 12 to protrude from the surface of the first side plate 13 facing away from the connecting plate 15 , the gap between the cabinet body 10 and the cabinet door 30 can be shielded to prevent rainwater from directly flowing into the gap between the cabinet body 10 and the cabinet door 30 from above.

[0106] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0107] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
