Specifically, the drain system may include a water collector 141, a return air duct 142, a drain air duct 143, and a drain fan 144.

The drain fan 144 may be configured to promote air flowing from the air inlet of the return air duct 142 to the air outlet of the drain air duct 143 through the water collector 141, so as to drain the defrosted water in the water collector 141 to the surrounding environment of the door 120. That is, under the action of the drainage fan 144, the ambient air around the air inlet of the return air duct 142 flows into the water collector 141 along the return air duct 142 through the air inlet of the return air duct 142, and drives the water vapor in the water collector 141 to flow along the drainage air duct 143, and flows into the indoor environment through the air outlet of the drainage air duct 143, thereby discharging the defrosting water.
In some embodiments, the heating pipe 135 and the drain fan 144 may be configured to operate after the separator 136 finishes driving the ice cubes each time, that is, defrosting the heat exchanging fins 133 and treating the defrosting water after ice making is finished each time, so as to reduce the amount of defrosting water generated by single defrosting and shorten the time required for single draining.
In some embodiments, the return air duct 142 and the drain air duct 143 may be disposed above the water collector 141, and the air inlet of the return air duct 142 and the air outlet of the drain air duct 143 may be disposed at two lateral ends of the top wall of the door 120, respectively, so as to improve the compactness of the door 120 and effectively reduce the defrosting water in the water collector 141.
The shortest distance between the drainage air duct 143 and the ice-making groove of the ice-making unit 130 may be greater than the shortest distance between the return air duct 142 and the ice-making groove of the ice-making unit 130, so as to prevent water vapor from being condensed in the drainage air duct 143, thereby achieving effective discharge of defrosting water.
In some embodiments, a drain fan 144 may be disposed at the air outlet of the drain air duct 143 to quickly diffuse water vapor in the indoor environment.
The drainage fan 144 may be an axial fan whose rotation axis coincides with the central axis of the air outlet of the drainage air duct 143, so that the drainage fan 144 may be hidden in the door 120, thereby avoiding an increase in the occupied space of the refrigerating and freezing apparatus 100.
Fig. 5 is a schematic perspective view of the water collector 141 of fig. 2 viewed from below upward. Referring to fig. 5, the bottom of the sump 141 may be provided with a heating wire 145 to heat the defrosting water inside the sump 141.
In case that the temperature of the indoor environment is equal to or higher than the preset temperature threshold and the humidity is equal to or higher than the preset humidity threshold, the heater wire 145 may be set to operate after the separator 136 completes driving of the ice cubes, and the drain fan 144 may be set to operate after the heater wire 145 operates for a preset time, so as to improve evaporation efficiency of the defrosting water and prevent more water vapor from being condensed in the sump 141.
Under the condition that the temperature of the indoor environment is less than the preset temperature threshold and the humidity is less than the preset humidity threshold, the drainage fan 144 may be set to start working while the heating pipe 135 starts to be the heat exchange fin 133, and work until the height of the frost water in the water collector 141 is less than or equal to the preset height threshold, so as to preheat the water collector 141 by using the ambient air, and enable the defrosting and the drainage to be performed simultaneously, thereby further shortening the drainage period.
The preset height threshold may be 0, that is, the drain fan 144 is operated to completely remove the defrosted water in the sump 141.
An insulating layer may be provided on the outer circumference of the water collector 141 to prevent condensation of the outer wall of the water collector 141 and reduce the influence of the cold of the ice-making compartment on the temperature of the water collector 141. The water collector 141 may be directly disposed in the foaming layer of the door 120, or may be disposed outside the foaming layer of the door 120 and separately coated with a heat insulating material.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model.
