Further, the air duct rear plate 140 further defines an air inlet 141a communicating the air supply duct 115 with the evaporator chamber, the blower 105 is disposed in the air supply duct 115 in a region corresponding to the air inlet 141a, the at least one first opening 120a may be located above the blower 105, and accordingly, the first air supply outlet 110a corresponding to the first opening 120a is formed at the upper portion of the air duct plate front body 111, so that the cold air flow flows through the entire space of the first storage compartment 102 from top to bottom.
A scroll air guide 141e is formed on the front wall of the duct rear plate 140 to extend around the outer circumference of the blower 105, and guides the air flow to the at least one first opening 120a, thereby reducing the wind loss and increasing the air blowing amount.
Since the temperature around the evaporator is extremely low and there is a risk of frost formation in the evaporator and the blower 105 downstream of the evaporator, the refrigerator 10 needs to be defrosted periodically, and generally, the bottom wall of the evaporator chamber, that is, the bottom wall of the inner container 101, is formed with a water pan having a drain opening in the area corresponding to the evaporator chamber, and the water pan receives the defrosted water and is drained through a drain pipe. The defrosting water of the evaporator may directly fall into the water receiving tray, and the defrosting water of the blower 105 may not directly fall into the water receiving tray, resulting in difficulty in draining water.
Therefore, in the present embodiment, a water collecting area (see fig. 4, which is not numbered) may be formed at the bottom of the volute air guide 141e, and a drain hole 141c is formed at a position of the duct rear plate 140 corresponding to the water collecting area, so that the defrosting water of the blower 105 is collected by the water collecting area, and the defrosting water flows out from the drain hole 141c and flows down to the water pan, thereby facilitating the drainage of the defrosting water of the blower 105.
In order to accelerate the downward flow of the defrosting water, the duct rear plate 140 may further be formed with a guide portion 141d protruding backward, and the guide portion 141d has a first guide surface (shown in fig. 3 and not numbered) extending downward from the lateral right side to the lower side of the drain hole 141c in an inclined manner and a second guide surface (shown in fig. 3 and not numbered) extending downward from the first guide surface from the lateral right side in an inclined manner, so as to guide the defrosting water to directly drop downward into the water receiving tray, thereby preventing the defrosting water from sliding down too slowly along the rear wall of the duct rear plate 140 and accelerating the discharge of the defrosting water.
