The rear cover is covered at the opening of the press bin and is provided with a penetrating air inlet;

the refrigerating assembly comprises a compressor, a condenser, a throttling device and an evaporator, wherein the evaporator is arranged in the box body and used for providing cold energy for the refrigerating compartment;

the dust cover is detachably connected to the rear cover and covers the air inlet;

The dust cover comprises a rear cover, an air inlet, a pressing machine bin, a dust cover, a back cover, a first limiting hook, a second limiting hook, a first limiting hook and a second limiting hook, wherein the front cover is provided with two protruding limiting hooks on one surface of the back cover, which is opposite to the pressing machine bin, the two limiting hooks are arranged at intervals along a first direction and distributed on two opposite sides of the air inlet, the two limiting hooks extend backwards and are bent in opposite directions, the two limiting hooks extend along a second direction, the first direction is perpendicular to the second direction, and the two opposite sides of the dust cover are clamped on the limiting hooks in a sliding mode along the second direction, so that the dust cover is detachably connected to the limiting hooks.

2. The refrigeration device according to claim 1, wherein limiting clamping grooves are respectively formed in two opposite sides of the dust cover, openings of the two limiting clamping grooves are arranged in a back-to-back mode, the two limiting clamping grooves extend in a second direction, and at least one end of the extending direction of the limiting clamping grooves is open, so that the limiting clamping grooves can be clamped on the limiting clamping hooks.

3. The refrigeration unit as recited in claim 2 wherein two of said retaining hooks are formed on two opposite edges of said air inlet, respectively, said retaining hooks being integrally formed on said air inlet edges.

4. The refrigeration unit as recited in claim 2 wherein a convex hook structure is formed on a side of said dust cover facing away from said rear cover, said hook structure being bent toward an edge of said dust cover after being convex rearward, and said limit slot being formed between a side of said dust cover facing away from said rear cover and said hook structure.

5. The refrigeration unit as recited in claim 1 wherein a protruding locating hook is formed at one end of said dust cover in the second direction, said locating hook protrudes from a face of said dust cover facing said rear cover, and a side of said locating hook facing away from the center of said dust cover is open, so that said locating hook can be engaged with an edge of said air inlet in the second direction.

6. The refrigeration unit as recited in claim 5 wherein said locating hooks are integrally stamped and formed on said dust cover.

7. The refrigeration unit as recited in claim 5 wherein said dust cover has a protruding stop tab formed at one end thereof in the second direction, said stop tab protruding from a side of the dust cover facing the press bin, and said rear cover has a stop slot recessed from a side of the rear cover facing away from the press bin, said stop tab being engageable in said stop slot to limit sliding movement of said dust cover relative to said rear cover.

8. The refrigeration appliance according to claim 7 wherein said stop tab and said locating detent are disposed adjacent respective edges of said dust cap in a second direction.

9. The refrigeration equipment according to claim 1, wherein the dust cover comprises a mesh cover and an outer frame surrounding the periphery of the mesh cover, the outer frame is detachably limited on the rear cover, and a plurality of hollowed mesh openings are formed in the mesh cover.

10. The refrigeration device of claim 1, wherein the second direction is a vertical direction, and the dust cover is connected to the limit hooks in a vertically slidable manner.
