However, these embodiments do not limit the present invention, and structural or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

As shown in fig. 1 to 10, the present invention provides a vacuum pump mounting box 100 for accommodating a vacuum pump and being placed in a refrigerator 500, wherein the refrigerator 500 includes a casing 5, an inner container 6 disposed in the casing 5, and a door body (not shown) opening and closing on the casing 5, and the casing 5 includes a rear plate 51, an upper plate 52, a lower plate (not shown) and two side plates 53 disposed opposite to the door body. The vacuum pump mounting box 100 includes an inner box for receiving the vacuum pump and an outer box 2 for receiving the inner box.

As shown in fig. 5, the inner case includes two sub-inner cases 10 fitted to each other and forming a receiving space for receiving the vacuum pump, and the outer case 2 includes two sub-outer cases 20 fitted to each other and forming another receiving space for receiving the inner cases. The opening direction of the sub inner case 10 is vertical, and the opening direction of the sub outer cases 20 is horizontal, and in the present embodiment, the opening of one sub outer case 20 faces the door, and the opening of the other sub outer case 20 faces the rear plate 51.

As shown in fig. 3 and 4, in the present embodiment, the outer box 2 is formed in a cube shape, and the length and height of the outer box 2 are the same and much larger than the width thereof, so that the outer box 2 has a flat shape as a whole and is fixed to the rear plate 51 of the refrigerator 500. In addition, a fixing hole 511 is formed in the rear plate 51 of the refrigerator 500, and the outer box 2 is just clamped on the fixing hole 511 and is abutted against the inner container 6 of the refrigerator 500. Accordingly, as shown in fig. 4, the inner container 6 is recessed towards the inner side of the inner container 6 at a corresponding position to form a groove 61, so that the outer box 2 can be partially accommodated in the groove 61. Therefore, two side surfaces of the outer box 2 are respectively abutted against the inner container 6 and the outer shell, so that the outer box 2 can be stably fixed between the inner container 6 and the outer shell. In addition, the vacuum pump mounting box 100 is arranged close to the rear side of the inner container 6 and the rear plate 51, so that the temperature of the vacuum pump can be effectively reduced, and the heat dissipation efficiency of the vacuum pump is improved.

Two outer boxes 20 of inferior of outer box 2 are connected fixedly through screw and nut, and are concrete, screw and nut all are provided with four, and distribute on four angles of inferior outer box 20. The depths of the two sub-outer boxes 20 are different, one depth is larger and is used for bearing the main containing function, the other depth is smaller and is used for bearing the covering function, and then for convenience of explanation, the sub-outer box 20 with the larger depth is recorded as a box body 21, and the sub-outer box 20 with the smaller depth is recorded as a cover body 22.

As shown in fig. 8, the cover 22 includes a cover 221 and a flange 222 protruding from the periphery of the cover 221, and the flange 222 is slightly recessed from four corners to the center for the screw to pass through. The cover plate 221 is provided with a first through hole 2211 so that the pipeline of the vacuum pump can pass through. In addition, a plurality of integrally formed chaste bars 2212 are arranged on the inner side of the cover plate 221, and the chaste bars 2212 are distributed in the cover plate 221 in a crossed manner, so that the chaste bars 2212 can effectively support the inner box, the friction force is increased, and the structure of the whole vacuum pump mounting box 100 is more stable.

As shown in fig. 6 and 7, the box body 21 includes a bottom plate 211 and four side plates 212 extending from the bottom plate 211, the side plates 212 are each formed with a positioning edge 2121 in a protruding manner in a direction perpendicular to the side plates 212, the positioning edges 2121 can perform a positioning effect, and when the vacuum pump mounting box 100 is mounted on the back plate of the refrigerator 500, the positioning edges 2121 can enable the vacuum pump mounting box 100 to be clamped on the back plate of the refrigerator 500 and prevent further insertion.

in addition, a limiting member 213 is formed inside at least one side plate 212, and the limiting member 213 is formed by bending and extending from the inside of the side plate 212, and has a supporting surface 2131 to support the outer surface of the inner box. Thereby can further reduce the area of contact of interior box and outer box 2 to being equivalent to making interior box unsettled setting in outer box 2, then the vacuum pump in the interior box at the during operation, the less transmission of vibrations ability to the outside.

As shown in fig. 7, specifically, the stoppers 213 are disposed on three side plates 212, but of course, since the vibration above the vacuum pump is small, the stoppers 213 are not disposed on the upper side plate 212, and two stoppers 213 are disposed on each side plate 212. In the present embodiment, in order to further enhance the damping effect, the vacuum pump mounting box 100 of the present invention further includes a damping pad 3, and the damping pad 3 is clamped to the limiting member 213.
