Specifically, the ice turning bar 460 specifically includes a rotating shaft and a cross bar disposed on the rotating shaft and corresponding to the number and position of the ice cells of the ice making cells 430, and when the ice turning bar 460 rotates, the cross bar turns out the ice cubes in the ice cells, so that the ice cubes are separated from the ice making cells 430 and fall into the ice storage container 500.
Referring to fig. 6 and 10, an upper cover plate 470 is erected at the top of the side of the ice making compartment 430, and is provided with an escape groove for receiving the ice-turning bar 460. The outer side of the upper cover plate 470 extends downward to form a side wing, and the side wing is provided with a plurality of wind holes 471.
Referring to fig. 15, when the fan assembly 420 is operated, the circulation fan 422 draws air from the suction side, that is, draws cool air from the air duct between the fixed tray 440 and the ice cube tray 430, and blows air to the air outlet side, or blows air forward if the air outlet side is forward in fig. 15. The cool air moves forward and downward, passes through the forward corner position of the ice making chamber 130 and the ice storage container 500 therebelow, continues to pass through the backward corner position of the ice making chamber 130 and the return duct between the drain pan 450 and the stationary pan 440, and is again sucked by the circulation fan 422 through the return hole in the bottom of the stationary pan 440. The air in the ice making chamber 130 exchanges heat in the wind circulation, so that the regions of the ice making unit 400 and the ice storage container 500 in the entire ice making chamber 130 are in a state of uniform temperature.
The present application provides a refrigerator with an ice making function, in which a pipe section of a refrigerant pipe 310 inserted into an ice making chamber 130 is in direct contact with an ice making tray 430, and cold energy is directly transmitted to the ice making tray 430, thereby effectively improving ice making efficiency. In addition, the fan assembly 420 for driving the air circulation in the ice making chamber 130 is integrated with other parts of the ice making unit, the ice making grid 430 is positioned at the suction side of the fan assembly 420, and the fan assembly 420 can directly suck cold air at the refrigerant pipe 310 to blow out the cold air into the ice making chamber 130, so that the air circulation is improved while the structure is simplified, the temperature balance state in the ice making chamber 130 is facilitated, and the problems of frosting, ice block adhesion or melting and the like caused by temperature difference are effectively solved.
In some embodiments of the present disclosure, a fixing plate 440 for tightly fixing the refrigerant pipe 310 to the bottom of the ice making tray 430 is disposed at the bottom of the ice making tray 430, so as to ensure effective contact between the refrigerant pipe 310 and the ice making tray 430, thereby ensuring sufficient heat transfer area between the refrigerant pipe 310 and the ice making tray 430, and enabling the cold energy generated by the refrigerant pipe 310 to be transferred to the ice making tray 430 most efficiently. And, an air duct is formed between the fixed tray 440 and the ice cube tray 430, and the fan assembly 420 may directly suck cold air in the air duct.
In some embodiments of the present application, a drain pan 450 is provided under the fixed tray 440 to receive overflow water or condensed water of the ice making compartments 430 to prevent water from dropping on the ice storage container 500 to freeze and stick ice cubes. And, an air return passage is formed between the drain pan 450 and the fixed pan 440, and air may flow back from the ice storage container 500 to the air return passage to be re-sucked by the blower assembly 420.
In some embodiments of the present application, the bottom of the fixed tray 440 is provided with a return hole 441, and air in the return duct can enter the ventilation duct through the return hole 441 and then be sucked by the fan assembly 420.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
