Through the vent hole 421, when the driving member 72 drives the lifting cover 71 to descend, the compressed air in the mounting cavity 711 can be discharged to the exterior of the water receiving box 4, thereby balancing the pressure in the mounting cavity 711.

[0086] In some embodiments, the refrigeration device may include a sealing ring 8. The sealing ring 8 can be sealingly sleeved on the lower end of the drain pipe 5. The lower end of the sealing ring 8 can protrude from the lower end of the drain pipe 5. When the driving member 72 drives the lifting cover 71 to rise, the top surface of the lifting cover 71 can block the lower end of the sealing ring 8, thereby preventing the drain pipe 5 from being connected to the water receiving chamber 41. When the driving member 72 drives the lifting cover 71 to descend. A gap can be formed between the lifting cover 71 and the sealing ring 8, thereby allowing the drain pipe 5 to be connected to the water receiving chamber 41, and then the evaporation chamber 3 can be connected to the water receiving chamber 41.

[0089] In some embodiments, the outer wall of the sealing ring 8 can be sealed against the peripheral side of the water inlet hole 441, thereby preventing water vapor outside the water receiving box 4 from entering the drain pipe 5, thereby preventing water vapor outside the water receiving box 4 from flowing into the evaporation bin 3, thereby preventing water vapor from frosting on the evaporator, thereby reducing the amount of frost on the evaporator, thereby extending the interval for starting the evaporator defrost program, and reducing the power consumption of the refrigeration equipment.

[0090] In some embodiments, the cover body 44 can be disposed on the bottom surface of the top plate of the press chamber 6, so that the water receiving box 4 can be disposed on the top of the press chamber 6, thereby reducing the space occupied by the water receiving box 4 in the press chamber 6, thereby increasing the space utilization in the press chamber 6 and reducing the volume in the press chamber 6.

[0091] In some embodiments, a through hole may be provided on the top plate of the compressor chamber 6. The through hole may be arranged opposite to the water inlet hole 441. The lower end of the sealing ring 8 may extend through the through hole and the water inlet hole 441 into the water receiving chamber 41. The outer peripheral wall of the sealing ring 8 may be sealed and connected to the peripheral side of the through hole, thereby preventing the water vapor in the box body 1 from entering the evaporation chamber 3, thereby preventing the water vapor from frosting on the evaporator, thereby reducing the amount of frost on the evaporator, thereby extending the interval for starting the evaporator defrosting program, thereby reducing the power consumption of the refrigeration equipment.

[0105] In some embodiments, the third rotating portion 7332 may be provided with a second groove 7333.
