The refrigerator 100 is divided into a refrigerating compartment 1 and a freezing compartment 2 in a vertical direction, and in other embodiments, the refrigerating compartment and the freezing compartment may be laterally arranged side by side. The refrigerating chamber 1 and the freezing chamber 2 are respectively provided with door bodies on the front side of the refrigerator 100, and the refrigerating chamber 1 and the freezing chamber 2 can be opened and closed by opening and closing the door bodies. The top of the refrigerating chamber 1 is provided with an ice-making chamber 11, the ice-making chamber 11 is separated from other areas of the refrigerating chamber 1 by a heat insulation wall 12, the heat insulation wall 12 can maintain the low temperature in the ice-making chamber 11 because the temperature in the ice-making chamber 11 is lower than the temperature in other areas of the refrigerating chamber 1, and the heat insulation material can be foam plastic or other heat insulation materials.

An ice maker 1122 is arranged in the ice making chamber 11, the ice maker 1122 is used for making ice, and the ice maker 1122 can select various types of ice makers 1122, and the selection modes are various, flexible and convenient. An ice making evaporator 1121 is further disposed in the ice making chamber 11, and a refrigerant flows through the ice making evaporator 1121, and heat is absorbed by evaporation of the refrigerant to freeze water into ice.

According to an embodiment of the present application, water supplied from a water source passes through a filter to filter impurities in the water to obtain drinkable water, and then is delivered to an ice maker 1122 through an ice maker water delivery pipe, and the ice maker 1122 makes the water into ice.

An ice bank 1111 is disposed below the ice maker 1122 in the ice making chamber 11, and the ice bank 1111 can store ice produced by the ice maker 1122.

The air in the ice making chamber 11 can also be transmitted to the freezing chamber 2 through the air duct 3, so as to prevent the moisture in the air from condensing on the surface of the ice making evaporator 1121 and the inner wall of the ice making chamber 11 and frosting, thereby improving the ice making efficiency and the refrigeration effect of the ice making chamber 11.

In the present example, since the refrigerating chamber 1 and the freezing chamber 2 are disposed up and down, the air duct 3 extends vertically between the refrigerating chamber 11 and the freezing chamber 2; when the refrigerating chamber 1 and the freezing chamber 2 are laterally disposed, the duct 3 laterally extends accordingly.

In this way, the temperature adjustment in the ice making chamber 11 in the present application can be achieved by introducing the cold energy of the freezing compartment 2, and there is no need to rely on the ice making evaporator 1121 to adjust the temperature of the ice making chamber 11.

In the present application, when the ice maker 1122 is not operating, for example, full ice and no ice is needed, the ice making evaporator 1121 may stop operating, which is more energy-saving than the problem in fig. 1 that the ice making evaporator 1121 also needs to operate to adjust the ice making compartment 11.

Because the air current circulation when ice making room 11 refrigerates in this application can directly borrow fan 211 in freezer 2 to realize, consequently, can omit fan 6 in ice making room 11 in fig. 1, simplified product structure, reduced product cost.

Air in the ice making chamber 11 contacts with ice blocks to cause water vapor to be carried in the air, the water vapor contacts with the ice making evaporator 1121 to cause the ice making evaporator 1121 to frost, so that the ice making efficiency of the ice making evaporator 1121 is reduced, and as the airflow in the ice making chamber 11 can flow into the freezing chamber 2 through the return air duct 32, the water vapor is prevented from frosting on the surface of the ice making evaporator 1121 and in the ice making chamber 11, and the ice making efficiency of the ice making evaporator 1121 is ensured; meanwhile, a defrosting device is not required to be arranged in the ice making chamber 11, so that the cost is reduced, and the structure is simple.

The air supply channel 113 makes the air flow of the air supply channel 31 orderly flow into the ice storage box 1111 from the air supply port 1131, so that the air flow flows along the air supply channel 113, the air flow sent by the air supply channel 31 and the air flow flowing out of the air return channel 32 are not directly mixed, the heat exchange efficiency of the air flow and the ice blocks in the ice making chamber 11 is improved, and the waste of cold energy is avoided.

In some embodiments of the refrigerator 100 of the present application, the air supply passage 113 divides the ice making chamber 11 into a first area 111 below the air supply passage 113 and a second area 112 above the air supply passage 113. The ice bank 1111 is located in the first region 111, and the ice making evaporators 1121 and the ice makers 1122 are located in the second region 112.

In some embodiments of the refrigerator 100 of the present application, the air supply channel 113 is enclosed by the partition 1132, the partition 1132 encloses the air supply channel 113 into a rectangular channel, or another type of channel, so as to avoid mixing of the air flow in the air supply duct 31 and the air flow in the ice making chamber 11 when the air flow just enters the ice making chamber 11, and also avoid the air flow just entering the ice making chamber 11 from directly flowing out from the return air duct 32, thereby ensuring that the air flow of the ice making chamber 11 entering from the air supply duct 31 can exchange heat sufficiently, and enhancing the heat exchange efficiency.

In some embodiments of the refrigerator 100 of the present application, the refrigerator 100 further comprises a blower fan 211 provided in the freezing compartment 2. The airflow between the freezing compartment 2 and the ice making compartment 11 is circulated by the fan 211. The fan 211 can provide power for the exchange of the air flows of the freezing compartment 2 and the ice making compartment 11 to circulate the air flow between the freezing compartment 2 and the ice making compartment 11.

In some embodiments of the refrigerator 100 of the present application, an evaporator 212 is also provided within the freezer compartment 2. The evaporator 212 and the fan 211 are located in the evaporator chamber 21 at the rear of the freezing chamber 2, and the evaporator chamber 21 is respectively communicated with the front region of the freezing chamber 2 and the air duct 3. The evaporator 212 is connected to the compressor and the condenser, and the low-temperature and low-pressure refrigerant absorbs heat while flowing through the evaporator 212 to provide cooling energy to the freezing chamber 2. The fan 211 can deliver a part of the cool air in the evaporator chamber 21 to the front region of the freezing chamber 2 and another part of the air to the ice making chamber 11.

In some embodiments of the refrigerator 100 of the present application, the ice making compartment 11 is provided at a rear portion thereof with a first tuyere 114 and a second tuyere 115 located below the first tuyere 114, and the evaporator chamber 21 is provided at a rear portion thereof with a third tuyere 213 and a fourth tuyere 214 located below the third tuyere 213. The two ends of the air supply duct 31 are respectively connected with the first air port 114 and the fourth air port 214, and the two ends of the air return duct 32 are respectively connected with the second air port 115 and the third air port 213. Because the first tuyere 114 is positioned above the second tuyere 115, the airflow sent by the first tuyere 114 directly enters the air supply channel 113, then slowly sinks into the ice storage box 1111 to provide cold energy for the ice cubes, and the airflow after heat exchange flows out of the ice storage box 1111, then sinks to the second tuyere 115 and flows out through the second tuyere 115. In the evaporator chamber 21, the fan 211 is provided above the evaporator 212, and the air flowing into the evaporator chamber 21 from the return air duct 32 is cooled by the evaporator 212 and then flows into the air supply passage through the fourth air port 214.

It should be noted that since the air flow flowing from the return air duct 32 is cooled by the evaporator 212, the evaporator 212 in the evaporator chamber 21 can be defrosted, and therefore the refrigerator 100 only needs to provide a defrosting device in the evaporator chamber 21, and does not need to additionally provide a defrosting device in the ice making evaporator 1121. The air in the ice making chamber 11 and the air in the evaporator cavity 21 circulate, so that the water content of the air in the ice making chamber 11 can be reduced, the ice making evaporator 1121 and the ice making chamber 11 are prevented from frosting, and the operation effect of the refrigerator 100 is improved.

In some embodiments of the refrigerator 100 of the present application, the air duct 3 is located within the foaming layer 5 of the refrigerator 100. The foaming layer 5 is made of heat insulating materials and can play a role in heat preservation, the air duct 3 is arranged in the foaming layer 5, the loss of cold energy of cold air in the air duct 3 can be reduced, the refrigeration efficiency of the refrigerator 100 is improved, meanwhile, the air duct 3 can be hidden, the air duct 3 is prevented from being distributed in the refrigerating chamber 1 and the freezing chamber 2, and the appearance is more attractive.

A fan 211 is provided in the evaporator chamber 21, and a part of the air is delivered to a front region of the freezing chamber 2, and another part of the air flow is delivered to the ice making chamber 11 through the air duct 3. The air in the evaporator chamber 21 flows into the ice making chamber 11 through the air supply duct 31, and after heat exchange in the ice making chamber 11 is completed, the air flows back to the evaporator chamber 21 through the air return duct 32.

An ice maker 1122 and an ice making evaporator 1121 are disposed in the ice making chamber 11, the ice making evaporator 1121 provides cold energy, the ice maker 1122 produces ice cubes, an ice storage bin 1111 is disposed below the ice maker 1122, and the ice storage bin 1111 can temporarily store the ice cubes. The air in the evaporator chamber 21 delivers an air flow through the air chute 3 for cooling the ice cubes in the ice bank 1111. The ice bank 1111 is provided with an ice dispensing opening 116, and the ice dispensing opening 116 is communicated with the ice outlet 41 of the dispenser 4, so that ice cubes can fall into the ice outlet 41 through the ice dispensing opening 116 to enter the dispenser 4 and then be delivered to the outside of the refrigerator 100 through the ice outlet 41.

According to the present application, since the problem of frost formation at the ice-making evaporator 1121 is solved, a defrosting structure is not required, the product structure is further simplified, and the product cost is reduced.

According to the present application, since the problem of frost formation at the ice making evaporator 1121 is solved, compared to the problem in fig. 1 that the ice making machine 1122 cannot operate when the ice making evaporator 1121 defrosts and the temperature of the ice making chamber 11 cannot be adjusted, the ice making machine 1122 of the present application can perform ice making operation, and the temperature of the ice making chamber 11 can be adjusted at any time.
