[0026] Combination Figures 1 to 3This application provides a refrigerator 1, including a freezer cavity 11, a baffle plate 1112, and a drawer assembly 12. An air supply channel 110 is provided in the freezer cavity 11, and an air outlet is provided in the air supply channel 110. The air supply channel 110 includes an air outlet 1111, and the air outlet can deliver the air in the air supply channel 110 to the freezer cavity 11 through the air outlet 1111. The air outlet 1111 is close to the opening end 11a of the freezer cavity 11. The baffle plate 1112 is disposed at the air outlet 1111. The drawer assembly 12 is slidably disposed in the freezer cavity 11. The drawer assembly 12 includes a front wall 121. When the drawer assembly 12 is completely disposed in the freezer cavity 11, the front wall 121 is close to the opening end 11a of the freezer cavity 11, and the baffle plate 1112 can guide the air from the air outlet 1111 to blow towards 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 ices on it. To mitigate or avoid this, an air supply duct 110 is provided inside the refrigerator 1, and an air outlet is provided within the air supply duct 110. When the freezer compartment 11 door closes, the air outlet is driven to deliver air from the air supply duct 110 to the air outlet 1111. The air delivered to the air outlet 1111 is guided by the deflector 1112 and then blown onto the front wall 121 of the drawer assembly 12, thus preventing frost or ice from forming on the front wall 121. If frost or ice forms on the front wall 121, the air blowing onto it can also remove the frost or ice, thus preventing any impact on the cooling efficiency of the refrigerator 1.

[0028] In one embodiment, reference is made to... Figure 1 The air supply duct 110 includes a first part 111, which is disposed on the inner wall 11b of the freezer cavity 11. An air outlet is disposed within the first part 111, and an air outlet 1111 is disposed within the first part 111. Because of the air outlet 1111 and its opening end 11a near the freezer cavity 11, when the drawer assembly 12 is fully disposed within the freezer cavity 11, the air outlet 1111 is positioned near the front wall 121 of the drawer assembly 12, enabling accurate defrosting of the front wall 121. Furthermore, the air outlet 1111 drawing air directly from the inner wall 11b of the freezer cavity 11 to the front wall 121 allows for more precise airflow guidance to the front wall 121, thereby achieving effective defrosting or de-icing of the front wall 121.

[0029] In one embodiment, reference continues... Figure 1There are two first parts 111, which are symmetrically arranged on the two inner side walls of the freezing chamber 11. By setting two first parts 111, the defrosting area corresponding to each first part 111 can be reduced, thereby enabling the deflector 1112 to guide the air to the front wall 121 more accurately.

[0030] It should be noted that, due to the symmetrical arrangement of the two first parts 111, therefore, the appendix... Figure 1 Only one of the same components in the first part 111 is labeled.

[0031] In one embodiment, reference continues... Figure 1 The air outlet is configured with a fan 114, which can deliver the air from the first part 111 to the air outlet 1111. The air outlet can be configured with a fan 114, which delivers the air in the air supply duct to the front wall 121 of the drawer assembly 12 through the air outlet 1111 and guided by the baffle 1112, thereby preventing the front wall 121 from frosting or icing.

[0032] In one embodiment, reference continues... Figure 1 The first part 111 also contains a heating wire 115, which is located between the fan 114 and the air outlet 1111. The heating wire 115 in the first part 111 heats the air within it, thereby increasing the temperature of the air exiting from the air outlet 1111. When the front wall 121 of the drawer assembly 12 is frosted or iced, the higher temperature of the air exiting from the air outlet 1111 can directly melt the ice or frost on the front wall 121, thus solving the problem of ice or 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, which in turn affects the cooling efficiency of the refrigerator 1.

[0033] In one embodiment, reference is made to... Figure 2 and Figure 3 A temperature sensor 117 is installed inside the freezer cavity 11 to detect the temperature inside the freezer cavity 11. When the door of the freezer cavity 11 closes, 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 can be turned off. At this time, no air is blown onto the front wall 121 of the drawer assembly 12, and ice or frost will not accumulate on the front wall 121. When the temperature of the freezer cavity 11 is lower than the certain temperature limit value, 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 of the air 111 to the freezer cavity 11 through the air outlet 1111. The air delivered to the air outlet 1111 is guided to the front wall 121 by the deflector 1112, thereby preventing frost or ice from forming on the front wall 121.

[0034] It should be noted that, in addition to determining whether to start the fan 114 by judging the temperature of the freezer cavity 11, the temperature difference between the inside and outside of the freezer cavity 11 can also be used to determine whether to start the fan 114 to blow air onto the front wall 121. For example, if the temperature difference between the inside and outside of the freezer cavity 11 is small when the door is open, the fan 114 does not need to be started after the door is closed. If the temperature difference is large, the fan 114 needs to be started to blow air onto the front wall 121 of the drawer assembly 12. Of course, other methods can also be used to determine whether to start the fan 114 to blow air onto the front wall 121, such as the number of times the freezer cavity 11 door is opened, the humidity outside the freezer cavity 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.

[0035] In one embodiment, reference is made to... Figure 3 The air supply duct 110 also includes a second part 112, which is located on the side away from the opening end 11a of the freezer cavity 11. The second part 112 is connected to the first part 111 and is provided with an air outlet 1121 that can discharge air into the freezer cavity 11. The first part 111 of the air supply duct 110 is used to discharge air into 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.

[0036] In one embodiment, reference is made to... Figure 3 The air supply duct 110 also includes a third part 113, which connects to the second part 112. The third part 113 is located at the bottom 11c of the freezer cavity 11 and has a return air inlet 1131 near the opening 11a of the freezer cavity 11. The third part 113 is mainly used for return air. An evaporator 116 is also installed in the third part 113. The air in the freezer cavity 11 flows back to the third part 113 through the return air inlet 1131 and is recooled by the evaporator 116 in the third part 113 to form cold air. When the freezer cavity 11 is being cooled, the cold air is discharged to the air outlet 1121 of the second part 112. The discharged air exchanges heat with the freezer cavity 11, thereby cooling the freezer cavity 11. The heat-exchanged air continues to enter the return air inlet 1131 and flows back to the third part 113, thus forming a cooling cycle in the freezer cavity 11. In addition, when the door of the freezer cavity 11 is opened to closed, in order to prevent frost or ice from forming on the front wall 121 of the drawer assembly 12, part of the air flowing from the third part 113 to the second part 112 flows into the freezer cavity 11 from the air outlet 1121, and the other part continues to flow to the first part 111 and is driven by the fan 114 to flow towards the air outlet 1111 and is guided by the deflector 1112 to the front wall 121.

[0037] In one embodiment, reference is made to... Figure 3 The deflector 1112 is rotatably mounted on the air outlet 1111 so that the deflector 1112 can adjust the airflow direction of the air outlet 1111. By setting the deflector 1112 to adjust the airflow direction of the air outlet 1111, the airflow direction of the air outlet 1111 can be accurately set, thereby enabling precise removal of frost from the front wall 121 of the drawer assembly 12.

[0038] In one embodiment, reference is made to... Figure 4 and Figure 5 The front wall 121 is provided with a vent 1211 to allow the interior of the drawer assembly 12 to communicate with the exterior of the drawer assembly 12. The vent 1211 is used to connect the interior space of the drawer assembly 12 with the exterior space of the drawer assembly 12, thereby ensuring that the gas inside the drawer assembly 12 can flow fully in the cavity formed between the front wall 121 of the drawer assembly 12 and the door.

[0039] 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.
