Referring to fig. 5, fig. 5 is a rear view of the refrigerator 1 according to an embodiment of the present invention, in which the outer case 102 is hidden. In addition, the refrigerating liner 120 may also be provided with a separate refrigerating return air pipe 70, an inlet of the refrigerating return air pipe 70 is connected to the refrigerating chamber 124, an outlet of the refrigerating return air pipe 70 is connected to the evaporator chamber 112, and the air after heat exchange in the refrigerating chamber 124 may return to the evaporator chamber 112 through the refrigerating return air pipe 70 to exchange heat with the evaporator 35, thereby forming a cycle.

Referring to fig. 4, in some embodiments, the refrigerator may further include a damper 92 disposed in the connecting duct member 90 to open and close the connecting duct member 90. Specifically, the damper 92 may also be of a sliding type or a rotating type, which is not limited by the present invention.

Referring to fig. 4, in some embodiments, the freezing liner 110 is further formed with a water collection groove 118 at the first opening 116 to collect the condensed water.

As can be seen from the foregoing description, the first end of the connecting duct member 90 needs to extend from the first opening 116 into the freezing chamber 110 and then connect with the second opening 440. The inventors have realized that: during use, due to aging of the sealing cotton, etc., there may be air leakage between the connecting air duct member 90 and the first opening 116, and once cold air leaks out of the connecting air duct member 90, water vapor in the leaked refrigerating air may condense into water drops and adhere to the outer wall of the connecting air duct member 90, and the first opening 116 may flow into the evaporator chamber 112 or the first air duct 410, and further frost may be formed in the evaporator chamber 112 or the first air duct 410, which may adversely affect various moving parts (a damper, a blower, etc.).

In the present embodiment, since the freezing inner container 110 is further formed with the water collection groove 118 at the first opening 116, the water collection groove 118 can collect the condensed water attached to the outer wall of the connecting air duct member 90, and the condensed water is prevented from flowing down along the connecting air duct member 90 into the evaporator chamber 112 or the first air duct 410, thereby reducing the adverse effect on the moving parts.

In addition, because the water collecting tank 118 is arranged at the first opening 116 of the freezing liner 110, the water collecting tank 118 can be specifically arranged above the top wall of the freezing liner 110, after the installation is completed, the position of the water collecting tank 118 can be covered by the insulating layer 104, the temperature in the insulating layer 104 is higher, and thus the condensed water collected in the water collecting tank 118 can be gradually evaporated and consumed, and the phenomenon of overflowing of excessive condensed water cannot be caused.

Referring to fig. 5, in some specific embodiments, the first opening 116 is a square hole having a flat shape, and a wider side of the first opening 116 extends in a lateral direction of the cabinet 10. The water collecting grooves 118 are two, and the two water collecting grooves 118 are formed at the wider side of the first opening 116, respectively.

The first opening 116 is a flat square hole, and a wider side of the first opening 116 extends in the lateral direction of the container 10. In order to better match the first opening 116 with the connecting air duct 90, the connecting air duct 90 may also be flat, and the wider side of the connecting air duct 90 extends along the transverse direction of the box 10, so that the connecting air duct 90 does not increase the sizes of the first air duct 410 of the freezing inner container 110 and the second air duct 122 of the refrigerating inner container 120 in the front-back direction, and further releases larger sizes of the freezing chamber 114 and the refrigerating chamber 124, and the structure is more reasonable.

The two water collecting grooves 118 are formed at the wider side of the first opening 116, so that the two water collecting grooves 118 can collect the condensed water on most of the outer wall of the main connecting air duct member 90, and the narrower ends of the two water collecting grooves 118 can be formed without the water collecting grooves 118, thereby simplifying the formation process of the water collecting grooves 118.

Further, the inner container wall of the freezing inner container 110 extends from the edge of the first opening 116 first to be away from the first opening 116 and downward, and then extends upward to form a water collecting groove 118.

That is, the water collecting groove 118 is formed by bending the inner container wall of the freezing inner container 110. The inner wall of the freezing inner container 110 extends upwardly away from the first opening 116 from a wider edge of the first opening 116 and downwardly, thus forming a catch basin 118 which opens upwardly, or the like. The forming method can be realized by bending and stamping only when the freezing inner container 110 is manufactured, and is simple and easy to implement.

Referring to fig. 4, in some embodiments, the refrigerator 1 may further include a first sealing ring 81, a second sealing ring 82, and a third sealing ring 83. The first seal ring 81, the second seal ring 82, and the third seal ring 83 may be made of sponge or the like.

The first sealing ring 81 is disposed in the water collection groove 118 and surrounds the connecting air duct member 90. On one hand, the first sealing ring 81 can absorb the condensed water collected in the water collecting tank 118 to accelerate evaporation; on the other hand, the first sealing ring 81 is used for sealing and connecting the gap between the air duct member 90 and the first opening 116, so as to prevent the refrigerant air flow in the freezing inner container 110 from being discharged from the gap between the air duct member 90 and the first opening 116, and reduce the probability of air leakage.

The second sealing ring 82 is located at the second opening 440 and surrounds the connecting air duct member 90 to seal the gap between the connecting air duct member 90 and the second opening 440 to prevent the refrigerant air flow in the first air duct 410 of the first air duct forming member 40 from leaking into the evaporator chamber 112.

The third sealing ring 83 is located at the third opening 126 and surrounds the connecting air duct member 90 to seal a gap between the connecting air duct member 90 and the third opening 126 to prevent the flow of the refrigerant from leaking out of the gap between the connecting air duct member 90 and the third opening 126.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
