Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 4, the filter screen structure of the present embodiment includes a housing 1, a filter element 2, an upper cover 3 and a turning plate 4, the filter element 2 is disposed in the housing 1, the housing 1 is a square frame, a supporting edge 12 is disposed at the bottom inner edge of the square frame, the bottom edge of the filter element 2 is abutted against the supporting edge 12, and the upper cover 3 capable of constraining the filter element 2 in the square frame is detachably disposed at the top of the square frame through a buckle, so as to facilitate installation and replacement of the filter element 2.

The sidewall of the housing 1 of this embodiment is provided with a receiving slot 11 for mounting the turning plate 4, the side of the turning plate 4 is rotatably connected to the corresponding sidewall of the receiving slot 11, the turning plate 4 rotates until the first edge 41 abuts against the bottom wall of the receiving slot 11, and the second edge 42 of the turning plate 4 opposite to the first edge 41 tilts outward toward the receiving slot 11 and forms a socket 10 together with the bottom wall of the receiving slot 11.

For the convenience of connection, a laterally extending rotating shaft 43 is disposed on the side wall of the turning plate 4 near the upper end, and correspondingly, a shaft hole 111 rotatably matched with the rotating shaft is disposed on the inner side wall of the accommodating groove 11. When the folding type refrigerator is not used, the turning plate 4 is hidden in the containing groove 11, and the front side wall of the turning plate 4 is approximately flush with the outer side wall of the shell 1 so as to keep the integral attractiveness.

The bottom of the receiving groove 11 has an opening 110, and the opening 110 is located on the lower edge of the housing 1, and the opening 110 forms an operation area for turning the turning plate 4 upwards.
