[0026] Combination Figures 1 to 3 This application provides a refrigerator 1, which includes a freezer cavity 11 and a drawer assembly 12. An air supply duct 110 is provided within the freezer cavity 11, and an air outlet is provided within the air supply duct 110. The air supply duct 110 is provided with an air outlet 1111, which can deliver air from the air supply duct 110 into the freezer cavity 11 through the air outlet 1111. The air outlet 1111 is located at the first end 110a of the air supply duct 110, that is, the end of the air supply duct 110 near the opening end 11a of the freezer cavity 11. The drawer assembly 12 is slidably disposed within the freezer cavity 11. Figure 3 , Figure 5 The drawer assembly 12 includes a front wall 121. When the drawer assembly 12 is fully installed in the freezer chamber 11, the front wall 121 is close to the opening end 11a of the freezer chamber 11. The air outlet 1111 is parallel to the front wall 121 so that the air outlet 1111 can discharge air to the front wall 121.

[0027] When the freezer compartment 11 door is opened, the front wall 121 of the drawer assembly 12 is exposed to the air. Moisture in the outside air easily encounters the cold front wall 121 and frosts or freezes on it. To mitigate or avoid this, an air supply duct 110 can be provided inside the refrigerator 1, and an air outlet can be provided within the air supply duct 110. When the freezer compartment 11 door is opened, the air outlet is driven to deliver the air in the air supply duct 110 to the air outlet 1111. The air coming out of the air outlet 1111 blows towards the front wall 121, and the air coming out of the air outlet 1111 is parallel to the front wall 121, thereby forming an air curtain on the front side of the front wall 121, thus preventing moisture outside the freezer compartment 11 from frostling or freezing on the front wall 121.

[0028] In one embodiment, reference Figure 2 and Figure 3 The air supply duct 110 includes a first part 111, which is located at the inner top 11b of the freezing chamber 11. An air outlet is located within the first part 111, and an air outlet 1111 is located within the first part 111. When the air outlet and the air outlet 1111 are located at the inner top 11b of the freezing chamber 11, the air blown out by the air outlet 1111 is from top to bottom, thus forming a downward air curtain. At this time, the downward air blown out by the air outlet 1111 needs to overcome less resistance, making it easier to form an air curtain.

[0029] It should be noted that the air outlet 1111 can also be set at the inner bottom 11c or inner side wall of the freezer cavity 11. In this case, the air blown out by the air outlet 1111 can also form an air curtain on the front wall 121 of the drawer assembly 12. The above is not restrictive and can be set according to the needs of those skilled in the art. All of the above are within the protection scope of this application.

[0030] In one embodiment, reference continues... Figure 2 and Figure 3The air outlet is configured as a fan 114, and a heating wire 115 is also installed in the first part 111, located between the air outlet 1111 and the fan 114. The air outlet can be configured as a fan 114, which delivers air from the air supply duct to the front side of the front wall 121 of the drawer assembly 12 through the air outlet 1111, thereby forming an air curtain. The heating wire 115 installed in the first part 111 can heat the air in the first part 111, thereby increasing the temperature of the air delivered from the air outlet 1111. At the same time, it can also reduce the temperature difference between the inside and outside of the freezer cavity 11 during the opening of the door, preventing frost from forming on the surface of the front wall 121. When the front wall 121 of the drawer assembly 12 is frosted, and the temperature of the air delivered from the air outlet 1111 is high, the high-temperature air curtain can defrost, thereby solving the problem of frost forming on the front wall 121 due to the large temperature difference between the inside and outside of the freezer cavity 11 when the user opens and closes the door.

[0031] The following description uses the example of an air outlet set as fan 114.

[0032] In one embodiment, reference continues... Figure 2 and Figure 3 A temperature sensor 117 is also installed inside the freezer cavity 11 to detect the temperature inside the freezer cavity 11. When the door of the freezer cavity 11 is opened, the temperature inside the freezer cavity 11 is detected. When the temperature of the freezer cavity 11 is higher than a certain temperature limit value, the fan 114 does not need to be turned on. At this time, no air curtain is formed on the front wall 121 of the drawer assembly 12, and frost or ice will not form on the front wall 121. However, when the temperature of the freezer cavity 11 is lower than the certain temperature limit value, the temperature difference between the inside and outside of the freezer cavity 11 is large. In order to avoid frost or ice forming on the front wall 121 and affecting the cooling effect of the freezer cavity 11, the fan 114 can be turned on. The fan 114 delivers the first part 111 of air to the freezer cavity 11 through the air outlet 1111, thereby forming an air curtain on the front side of the front wall 121, thus preventing frost or ice from forming on the front wall 121.

[0033] It should be noted that, in addition to determining whether to start the fan 114 by judging the temperature of the freezing chamber 11, the temperature inside and outside the freezing chamber 11 can also be detected, and the temperature difference between the inside and outside of the freezing chamber 11 can be used to determine whether to start the fan 114 to blow air onto the front wall 121. Of course, other methods can also be used to determine whether to start the fan 114, such as the number of times the door of the freezing chamber 11 is opened, the humidity outside the freezing chamber 11, the number of times the compressor starts and stops, or any two or more of the above methods. The above is not limiting and can be set according to the needs of those skilled in the art.

[0034] In one embodiment, reference Figure 3The air outlet 1111 is located on the side of the first part 111 facing the freezer cavity 11. The air blown out by the air outlet 1111 directly forms an air curtain on the front side of the front wall 121 of the drawer assembly 12. Therefore, when the side of the air outlet 1111 facing the first part 111 facing the freezer cavity 11 is facing downward, it is easier to form an air curtain when blowing air, thereby more effectively isolating the front wall 121 from the air outside the freezer cavity 11.

[0035] It should be noted that the air outlet 1111 can be directly facing the side of the first part 111 facing the freezing chamber 11. Of course, it can also be set in other directions, such as tilting towards the inner top 11b of the freezing chamber 11. In this case, the air coming out of the air outlet 1111 can be reflected by the inner top 11b of the freezing chamber 11. The reflected air can also form an air curtain on the front side of the front wall 121. Therefore, the orientation of the air outlet 1111 can be set according to the needs of those skilled in the art. All of the above are within the protection scope of this application.

[0036] In one embodiment, reference continues... Figure 3 The air supply duct 110 also includes a second part 112, which is connected to the first part 111 and located on the side away from the opening end 11a of the freezer cavity 11. The second part 112 is provided with an air outlet 1121 for discharging air into the freezer cavity 11. The first part 111 of the air supply duct 110 is used to discharge air to the front wall 121 of the drawer assembly 12, and the second part 112 is used to discharge air into the freezer cavity 11, thereby ensuring that the freezer cavity 11 can circulate cooling.

[0037] In one embodiment, reference continues... Figure 3The air supply duct 110 also includes a third part 113, which is located at the inner bottom 11c of the freezing chamber 11. The third part 113 is connected to the second part 112 and is provided with a return air port 1131. The return air port 1131 is close to the opening end 11a of the freezing chamber 11, and the air in the freezing chamber 11 can flow back to the third part 113 through the return air port 1131. The third part 113 is mainly used for air return. The air in the freezing chamber 11 flows back to the third part 113 through the return air port 1131 and is recooled in the third part 113 to form cold air. When the freezing chamber 11 is being refrigerated, the formed cold air is discharged to the air outlet 1121 of the second part 112. The discharged air exchanges heat with the inside of the freezing chamber 11, thereby refrigerating the inside of the freezing chamber 11. The air after heat exchange continues to enter the return air port 1131 and flows back to the third part 113, thus forming a refrigeration cycle in the freezing chamber 11. Additionally, when the door of the freezer chamber 11 is opened and it is necessary to prevent frost or ice from forming on the front wall 121 of the drawer assembly 12, a portion of the air flowing from the third part 113 to the second part 112 flows into the freezer chamber 11 from the air outlet 1121, while the other portion continues to flow to the first part 111 and is driven by the fan 114 to deliver air from the air outlet 1111 to the front wall 121, thereby forming an air curtain.

[0038] In one embodiment, reference continues... Figure 3 An evaporator 116 is also installed in the third part 113. The evaporator 116 installed in the third part 113 can cool the air returning to the third part 113 from the return air port 1131 in a timely manner, thereby ensuring that the air flowing from the third part 113 to the second part 112 and out of the air outlet 1121 is cold air.

[0039] In one embodiment, reference Figure 4 Multiple air outlets 1111 are provided, and the multiple air outlets 1111 are arranged side by side in the first part 111, blowing air towards the front wall 121. In order to ensure that the air blown out of the air outlets 1111 can form an air curtain, the multiple air outlets 1111 are arranged side by side, so that the air blown out from the multiple air outlets 1111 forms a uniform air curtain on the front side of the front wall 121.

[0040] In one embodiment, reference continues... Figure 4 The spacing between any two adjacent air outlets 1111 is equal. The equal spacing between adjacent air outlets 1111 further ensures the uniformity of the air curtain formation.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
