The refrigerator further includes a drain pipe 80 for discharging the evaporator defrost water, and the exhaust pipe 21 of the vacuum pump 20 communicates with the drain pipe 80.

The exhaust air of the vacuum pump 20 is exhausted through the drain pipe 80, so that the temperature fluctuation of the refrigerating chamber 10 caused by the direct exhaust of the exhaust air to the refrigerating chamber 10 is avoided, and the constant temperature performance of the refrigerating chamber 10 is improved.

The specific arrangement position of the water discharge pipe 80 is not particularly limited in this embodiment, and the water discharge pipe 80 and the air discharge pipe 21 are arranged and communicated with each other reasonably.

In some embodiments of the present application, the vacuum pump 20 is disposed on the inner container 11 of the refrigerating chamber 10, an insulating layer is disposed outside the inner container 11 of the refrigerating chamber, and the exhaust pipe 21 is introduced into the insulating layer through the inner container of the refrigerating chamber 10 and is communicated with the drain pipe 80.
