Referring to fig. 1 to 6, a preferred embodiment of the present utility model provides a refrigerator having an ice making function to meet a user's ice making needs.

Specifically, as shown with reference to fig. 1 and 2, a refrigerator includes an ice making compartment housing 10, an ice making device 20, a cold guide 30, a refrigerant pipe 40, and a fan assembly 50.

Specifically, the ice making compartment case 10 has an ice making compartment 11 and an air inlet 12 communicating with the ice making compartment 11. In this embodiment, the ice making chamber housing 10 further has an air outlet 19 communicating with the ice making chamber 11, and the air in the ice making chamber 11 flows out through the air outlet 19 and flows back into the ice making chamber 11 through the air inlet 12, thereby forming a circulating air flow in the ice making chamber 11, so that the temperatures of the respective portions of the ice making chamber 11 tend to be equal.

Specifically, the ice making device 20 is disposed in the ice making compartment 11, and includes an ice making tray 21. In the present embodiment, after the ice making device 20 is installed in the ice making compartment 11, the cooling capacity required for making ice can be obtained by exchanging heat in the ice making compartment 11. The ice tray 21 includes a plurality of ice cubes, and after the ice cubes are filled with water, the ice cubes can be made after the water in the ice cubes has acquired sufficient cooling capacity.

Specifically, the cold guide 30 is disposed in the ice making compartment 11. In the present embodiment, the cold guide 30 serves to transfer the cold of the refrigerant pipe 40 into the ice making compartment 11, thereby accelerating the cooling of the ice making compartment 11.

Specifically, at least a portion of the refrigerant pipe 40 is located between the ice making tray 21 and the cold guide 30. In this embodiment, the refrigerant pipe 40 is connected to the condenser and the compressor through a pipeline to form a refrigeration circuit together, so as to provide cooling capacity for the ice making device 20 in the ice making compartment. The ice making compartment 11 is cooled by the refrigerant pipe 40, thereby realizing direct cooling of the ice making compartment 11. The refrigerant pipe 40 is attached to the ice making tray 21 and the cold guide 30, or the refrigerant pipe 40 contacts the ice making tray 21 and the cold guide 30, so that the cooling capacity can be better transferred to the ice making tray 21 and the cold guide 30, and the cooling of the ice making device 20 and the ice making compartment 11 can be accelerated.

Specifically, the fan assembly 50 includes an air outlet 51 that interfaces with the air inlet 12. In this embodiment, the fan assembly 50 is capable of forming a unidirectional airflow, and the formed airflow is discharged from the air outlet 51 and flows into the ice making compartment 11 through the air inlet 12.

Specifically, as shown in fig. 3, the cold guide 30 has a first cold guide plate 31 located at the bottom of the ice making tray 21 and a second cold guide plate 32 located between the ice making tray 21 and the side wall of the ice making compartment case 10. In the present embodiment, the second cold guide plate 32 is opposite to at least one side wall of the ice making housing 10, for example, the front side wall, the left side wall, the right side wall, etc. of the ice making housing 10 in fig. 1, that is, the second cold guide plate 32 may be located at the front side, the left side, or the right side of the ice making tray 21. The plane of the first cold guide plate 31 and the plane of the second cold guide plate 32 form a certain angle, for example 90 degrees, so as to form an L-shaped structure.

Further, a first passage 60 is formed between the second cold guide plate 32 and the opposite side wall of the ice making housing 10, and a top opening of the first passage 60 is opposite to the air inlet 12. In this embodiment, the second cold guide plate 32 is spaced apart from the opposite side wall of the ice making compartment case 10 to form the first passage 60, and the first passage 60 preferably extends in the vertical direction, i.e., the air flow in the first passage 60 flows in the vertical direction. The top opening of the first passage 60 is butted with the air inlet 12, i.e., the inlet of the first passage 60 communicates with the air inlet 12, so that the air flow flowing into the ice making compartment 11 from the air inlet 12 directly flows to the first passage 60.

After being discharged from the air outlet 51, the air flow formed by the fan assembly 50 flows to the top of the first channel 60 through the air inlet 12, flows downwards through the first channel 60 and flows to all the positions of the ice making compartment 11, so that concentrated frosting is avoided at the bottom of the ice making device 20, and the normal flow of the air in the ice making compartment 11 is ensured.

Specifically, the refrigerator further includes a water tray 70 at the bottom of the ice-making tray 21. In this embodiment, the water tray 70 is used to receive water flowing down from the ice making device 20 or the cold guide 30, such as condensation generated when the ice making device 20 heats and de-ices, or defrosting water generated when the cold guide 30 defrosts.

Further, a second channel 80 is formed between the water pan 70 and the first cold guide plate 31, and the second channel 80 is communicated with the bottom opening of the first channel 60. In this embodiment, the second passage 80 extends in the horizontal direction, i.e., the air flow in the second passage 80 flows in the horizontal direction. The second channel 80 communicates with the bottom opening of the first channel 60, i.e. the inlet of the second channel 80 interfaces with the outlet of the first channel 60. As shown in fig. 3, the air flow flowing into the ice making compartment 11 through the air inlet 12 sequentially passes through the first and second passages 60 and 80 and then flows to the respective portions of the ice making compartment 11, so that the air flow with moisture is uniformly frosted on the respective portions of the ice making device 20, i.e., the first cold guide plate 31 at the bottom of the ice making device 20 and the second cold guide plate 32 at the side of the ice making device 20. Because the first cold guide plate 31 and the second cold guide plate 32 are in an L-shaped structure, the air flow in the first channel 60 and the second channel 80 is also in an L-shaped structure, so that the air flow is slowed down, and the cooling capacity on the refrigerant pipe 40 and the cold guide piece 30 is convenient to radiate to the whole ice making compartment 11 along with the air flow.

Further, the ice making housing 10 has a guide portion 13 opposite to the second cold guide plate 32 and a first guide portion 14 connected to a lower end of the guide portion 13, and a distance between the first guide portion 14 and the second cold guide plate 32 is gradually reduced from top to bottom. In this embodiment, the first guiding portion 14 is disposed on the side wall of the ice making compartment housing 10 opposite to the second cold guide plate 32, the first guiding portion 14 is disposed at the bottom of the first channel 60, and the first guiding portion 14 is disposed obliquely, so that the air flow in the first channel 60 and the air flow flowing out of the first channel can be guided, and the air flow smoothly flows into the second channel 80. In addition, the defrost water on the cold guide 30 or the condensation formed on the side wall of the ice making compartment case 10 can be introduced into the water receiving tray 70.

Further, the ice making housing 10 has a guide portion 13 and a second guide portion 15 connected to an upper end of the guide portion 13, and a distance between the second guide portion 15 and the second cooling plate 32 increases gradually from top to bottom. In this embodiment, a second guiding portion 15 is further disposed between the first channel 60 and the air inlet 12, and the second guiding portion 15 is located at the top of the first channel 60, so that the air flow flowing into the ice making compartment 11 from the air inlet 12 smoothly flows into the first channel 60.

The second cold guide plate 32 is preferably opposite to the front sidewall of the ice making housing 10 such that the circulating air flow passes through the front of the ice making device 20 and then passes through the bottom of the ice making device 20, thereby preventing the circulating air flow with moisture from being concentrated and frosted at the bottom of the ice making device 20. The guide part 13, the first guide part 14 and the second guide part 15 are disposed on the front sidewall of the ice making compartment case 10, and the first passage 60 is formed between the guide part 13 and the second cold guide plate 32.

Further, the ice making housing 10 includes a compartment liner 16 and a mounting bracket 17 coupled to the compartment liner 16. In the present embodiment, the ice making housing 10 is provided in a separate type, so that the ice making device 20, the cold guide 30, etc. can be easily installed. The ice making tray 21 and the cold guide 30 are connected to the mounting bracket 17.

Specifically, the refrigerator further includes an ice bank 90 disposed in the ice making compartment 11, and at least a portion of the ice bank 90 is positioned below the ice making device 20 for storing ice cubes formed by the ice making device 20. The compartment inner 16 has a compartment opening 18 opposite the mounting bracket 17, and a user can take and put the ice bank 90 through the compartment opening 18.

Specifically, the second cold guide plate 32 is positioned between the ice making tray 21 and the mounting bracket 17, and the first passage 60 is formed between the second cold guide plate 32 and the mounting bracket 17. In the present embodiment, the mounting bracket 17 is preferably provided on the front side of the second cold guide plate 32 so that the mounting bracket 17 is opposed to the compartment opening 18 in the front-rear direction. Forming the guide part 13, the first guide part 14, and the second guide part 15 on the mounting bracket 17 can reduce the difficulty of manufacturing the ice making housing 10.

Further, as shown in fig. 4, the water tray 70 has a bottom plate 71 opposite to the first cold guide plate 31, a side plate 72 opposite to the outlet of the second channel 80, and a guide structure provided on the side plate 72, the guide structure including a guide hole 73 provided on the side plate 72 and a guide plate 74 connected to the side plate 72, the guide plate 74 being connected to an upper edge of the guide hole 73 and being inclined with respect to a horizontal plane so that the air flow flowing out of the guide structure flows obliquely downward.

In this embodiment, as shown in the airflow illustration in fig. 3, a guiding structure is disposed on the side plate 72 at the rear end of the bottom plate 71, that is, the guiding structure is located at the outlet of the second channel 80, so that a part of the airflow flowing out of the second channel 80 flows obliquely downward, thereby guiding the airflow into the ice storage box 90, and avoiding the ice cubes of the ice storage box 90 from adhering. A guide plate 74 is attached to the front side of the side plate 72, and the guide plate 74 is disposed obliquely forward and upward from one end attached to the side plate 72.

As shown in fig. 4, the water receiving tray 70 preferably has a plurality of guide structures arranged in the left-right direction.

As shown in fig. 4, the lower side wall of the guide hole 73 is inclined in parallel to the inclined direction of the guide portion 74. The inlet of the second channel 80 interfaces with the outlet of the first channel 60.
