Refrigerator 00 may be a refrigerator with a single door, double doors, or multiple doors. Different numbers of door bodies 20 may correspond to different areas of the refrigerator 00, and different areas of the refrigerator 00 may implement different functions, for example, the box body 10 of the refrigerator 00 may be divided into a refrigerating compartment and a freezing compartment, and the refrigerating compartment and the freezing compartment are respectively provided with one door body 20. The door bodies 20 are separately arranged in different areas of the refrigerator 00, so that the areas of the refrigerator 00 are not influenced when the refrigerator 00 is opened and closed, for example, the door body 20 of the cold storage chamber is opened without influencing the freezing chamber. The embodiment and the drawings of the present application take the refrigerator 00 as a refrigerator with two doors as an example for explanation, but the embodiment of the present application does not limit the specific number of the door bodies 20 of the refrigerator 00.

Referring to fig. 2, fig. 2 is another schematic structural diagram of a refrigerator according to an embodiment of the present application.

In general, the refrigerating compartment 01 is provided near the top of the refrigerator 00 and the freezing compartment 02 is provided near the bottom of the refrigerator 00, so that the refrigerating compartment 01 is located above the freezing compartment 02. However, in some small-capacity refrigerators, the volume of the refrigerating compartment 01 is much larger than that of the freezing compartment 02, and in this case, the refrigerating compartment 01 is disposed near the bottom of the refrigerator 00 and the freezing compartment 02 is disposed near the top of the refrigerator 00, so that the refrigerating compartment 01 is located below the freezing compartment 02. The specific locations of the refrigerating compartment 01 and the freezing compartment 02 of the refrigerator 00 are not limited in the embodiments of the present application.

The refrigerator 00 can include an evaporator 30, an air duct assembly 40, and a valve structure 50. The evaporator 30 is disposed in the freezing compartment 02 of the refrigerator 00, one portion of the air duct assembly 40 is located in the refrigerating compartment 01 of the refrigerator 00, the other portion of the air duct assembly 40 is located in the freezing compartment 02 of the refrigerator 00, and the valve structure 50 is disposed in the air duct assembly 40. It is to be understood that the structure of the refrigerator 00 is not limited thereto, and may further include other components such as a compressor, a condenser, a dew-proof pipe, a filter, a return air pipe assembly, etc. (none of which are shown). The description of the above components can refer to the description in the related art, and will not be repeated here.

The evaporator 30 is used to generate cool air for the refrigerator 00. The evaporator 30 may be a fin evaporator, and the refrigerant evaporates in the evaporator 30 to absorb heat, exchanges heat with the ambient air, and lowers the temperature of the ambient air to form low-temperature cold air. The cold air generated by the evaporator 30 may be delivered to the refrigerating compartment 01 and the freezing compartment 02 of the refrigerator 00 to refrigerate or freeze the items in the refrigerator 00.

However, in some small-capacity refrigerators, the volume of the refrigerating compartment 01 is much larger than that of the freezing compartment 02, and in this case, the refrigerating compartment 01 is disposed near the bottom of the refrigerator 00 and the freezing compartment 02 is disposed near the top of the refrigerator 00, so that the refrigerating compartment 01 is located below the freezing compartment 02, and the evaporator 30 may be disposed in the refrigerating compartment 01.

The duct assembly 40 is used to deliver cool air to the refrigerator 00. The air duct assembly 40 is provided with a plurality of first air outlets 401, a plurality of second air outlets 402 and at least one third air outlet 403. All the first air outlets 401 are communicated with the inside of the refrigerating chamber 01 of the refrigerator 00, and the air duct assembly 40 can convey cold air generated by the evaporator 30 to the refrigerating chamber 01 through the first air outlets 401 to refrigerate the refrigerating chamber 01; all the second air outlet 402 and the third air outlet 403 are communicated with the interior of the freezing compartment 02 of the refrigerator 00, and the second air outlet 402 and the third air outlet 403 through which the air duct assembly 40 can pass convey the cold air generated by the evaporator 30 to the freezing compartment 02 to refrigerate the freezing compartment 02.

The valve structure 50 is used to control the rate at which the duct assembly 40 delivers cold air to the freezer compartment 02 of the refrigerator 00. The valve structure 50 is disposed in the air duct assembly 40 and near the third air outlet 403, and the valve structure 50 can selectively open or close the third air outlet 403 to control the speed of the air duct assembly 40 for delivering the cool air to the freezing compartment 02. When the valve structure 50 opens the third air outlet 403, all air outlets of the air duct assembly 40 communicating with the freezing compartment 02 are opened, so that the speed of conveying cold air to the freezing compartment 02 by the air duct assembly 40 is high; when the valve structure 50 closes the third air outlet 403, a portion of the air outlet of the air duct assembly 40 communicating with the freezing compartment 02 is opened, and a portion of the air outlet is closed, so that the speed of delivering cold air to the freezing compartment 02 by the air duct assembly 40 is relatively low.

The refrigerator 00 provided by the embodiment of the application comprises a refrigerating chamber 01 and a freezing chamber 02 which are separated from each other, an evaporator 30 is arranged in the freezing chamber 02, air duct assembly 40 is used for conveying cold air to the refrigerating chamber 01 through a plurality of first air outlets 401, the air duct assembly 40 is used for conveying cold air to the freezing chamber 02 through a plurality of second air outlets 402 and at least one third air outlet 403, and a valve structure 50 is arranged in the air duct assembly 40, so that the valve structure 50 selectively opens or closes the third air outlets 403 to control the speed of conveying the cold air to the freezing chamber 02 by the air duct assembly 40, and the problems that when the refrigerating chamber 01 needs to convey the cold air, the temperature in the freezing chamber 02 is unstable and the power consumption of the refrigerator is increased due to passive refrigeration of the freezing chamber 02 are solved.

Referring to fig. 3, fig. 3 is a schematic structural view of a duct assembly in the refrigerator shown in fig. 2. The air duct assembly 40 may include a refrigerated air duct 41 and a refrigerated air duct 42. All the first air outlets 401 are arranged in the refrigerating air duct 41, and the refrigerating air duct 41 is communicated with the inside of the refrigerating compartment 01 through the first air outlets 401 and is used for conveying cold air to the refrigerating compartment 01; all the second air outlets 402 and the third air outlets 403 are opened in the freezing air duct 42, and the freezing air duct 42 is communicated with the inside of the freezing compartment 02 through the second air outlets 402 and the third air outlets 403 and used for conveying cold air to the freezing compartment 02.

Since evaporator 30 is disposed in freezing compartment 02 of refrigerator 00 and refrigerating compartment 01 of refrigerator 00 does not have a separate cooling capability, cool air supplied to refrigerating compartment 01 by refrigerating duct 41 is supplied from freezing duct 42. Therefore, the refrigerating duct 41 needs to communicate with the freezing duct 42 so that the cool air in the freezing duct 42 can be delivered into the refrigerating duct 41. The cold air generated by the evaporator 30 can be delivered to the freezing compartment 02 through the second air outlet 402 and the third air outlet 403 via the freezing air duct 42, but the cold air generated by the evaporator 30 can be delivered to the refrigerating compartment 01 through the first air outlet 401 via the freezing air duct 42 and the refrigerating air duct 41.

The duct assembly 40 may further include a duct attachment foam 43 and a damper (not shown). Wherein, one end of the air duct connecting foam 43 is connected with the freezing air duct 42, and the other end is connected with the refrigerating air duct 41, so as to connect the refrigerating air duct 41 with the freezing air duct 42. An air inlet 430 is further disposed between the refrigerating air duct 41 and the freezing air duct 42, and the refrigerating air duct 41 is communicated with the freezing air duct 42 through the air inlet 430. A damper is also disposed between the refrigerating air duct 41 and the freezing air duct 42, and the damper can selectively open or close the air inlet 430. When the air door opens the air inlet 430, the refrigerating air duct 41 is communicated with the freezing air duct 42, and cold air in the freezing air duct 42 can enter the refrigerating air duct 41, so that the cold air is conveyed to the refrigerating chamber 01; when the air inlet 430 is closed by the air door, the refrigerating air duct 41 is separated from the freezing air duct 42, and the cold air in the freezing air duct 42 cannot enter the refrigerating air duct 41, so that the cold air delivery to the refrigerating compartment 01 is stopped.

Referring to fig. 3 and 4 together, fig. 4 is a schematic view illustrating a structure of a freezing air duct in the air duct assembly shown in fig. 3. The air chute assembly 40 may further include a fan 44. A fan 44 is disposed in the freezing air duct 42 for blowing the cold air generated by the evaporator 30 to form cold air. After entering the freezing air duct 42, the cold air generated by the evaporator 30 is blown by the fan 44 to form cold air, and the cold air is continuously blown into the freezing compartment 02 by the fan 44 through the second air outlet 402 and the third air outlet 403, and is also blown into the refrigerating air duct 41 by the fan 44 through the air inlet 430, and is further blown into the refrigerating compartment 01 through the first air outlet 401.

Wherein, the refrigerating air duct 41 is further provided with an air return opening 404, and the air return opening 404 is communicated with the inside of the refrigerating compartment 01. After the fan 44 blows cold air into the refrigerating air duct 41 through the air inlet 430 and further into the refrigerating compartment 01 through the first air outlet 401, the cold air cools the refrigerating compartment 01, and then flows out of the refrigerating compartment 01 through the air return opening 404 and finally flows back to the freezing compartment 02.
