For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] During operation of an existing refrigerator, cold air can only be supplied to the freezer compartment of the refrigerator from a set position. The density of the cold air is relatively large and the cold air can only be refrigerated gradually from the lower part of the freezer compartment to the upper part of the freezer compartment, so that items placed in the upper part of the freezer compartment cannot quickly reach the set temperature, which seriously affects the freezing effect and storage reliability of the refrigerator.

[0036] To this end, the present application provides a Figures 1 to 5The air duct assembly shown includes: an air duct back plate 1; an air duct panel 2, the air duct panel 2 is arranged on the air duct back plate 1, and the air duct panel 2 is provided with a first air supply port 21 and a second air supply port 22; an air duct rib 3, the air duct rib 3 is arranged between the air duct panel 2 and the air duct back plate 1, and the air duct rib 3, the air duct panel 2 and the air duct back plate 1 together form a fan cavity 41 and an air supply duct 42, the first air supply port 21 and the second air supply port 22 are arranged on the air duct panel 2; 2 is connected with different positions of the air supply duct 42; at least two air outlets are arranged on the air duct rib 3, the fan chamber 41 is connected with the air supply duct 42 through all the air outlets, and the air outlet direction of at least one of the air outlets points to the first air supply outlet 21, and the air outlet direction of at least one of the air outlets points to the second air supply outlet 22; a baffle, the baffle corresponds to the air outlet one by one, and the baffle has a first state of opening the corresponding air outlet and a second state of closing the air outlet. By arranging the first air supply port 21 and the second air supply port 22 at different positions on the air duct panel 2, the air duct component can supply air to different positions of the compartment where it is located, so that different positions of the compartment are cooled to ensure the cooling effect and preservation effect of the compartment, and the air ports with different air outlet directions are used to control the flow direction of the cold air in the fan cavity 41, so that the cold air can be guided to the first air supply port 21 and / or the second air supply port 22 through different parts of the air supply duct 42, and a baffle is also provided to control the working state of the air port, and the air supply volume of the first air supply port 21 and the second air supply port 22 can be controlled, thereby further increasing the cooling effect at different positions of the compartment, and improving the cooling effect and storage reliability of the refrigeration equipment.

[0037] When the air duct assembly is arranged in the refrigeration equipment, the air duct assembly constitutes the side wall of the freezing compartment in the refrigeration equipment, and the freezing compartment is cooled by sending cold air through the air duct assembly, wherein the cold air generated by the refrigeration equipment first enters the fan cavity 41, then enters the air supply duct 42 through the air outlet, and finally is sent into the freezing compartment through the first air supply outlet 21 and the second air supply outlet 22, and is transported to different positions of the freezing compartment through the first air supply outlet 21 and the second air supply outlet 22. When the temperature of the freezing compartment corresponding to the first air supply outlet 21 is less than When the temperature of the freezer compartment corresponding to the first air supply port 21 meets the requirement, the baffle of the air outlet corresponding to the first air supply port 21 is controlled to be adjusted (switched to the first state), so that the cold air in the fan chamber 41 can flow to the first air supply port 21 through this air outlet, and finally be sent into the freezer compartment for refrigeration. When the temperature of the freezer compartment corresponding to the first air supply port 21 meets the requirement, the baffle of the air outlet corresponding to the first air supply port 21 is controlled to be switched to the second state. At this time, the cold air in the fan chamber 41 is not sent into the freezer compartment through the first air supply port 21, thereby reducing the energy consumption of the refrigeration equipment. Similarly, when the temperature of the freezer compartment corresponding to the second air supply port 22 does not meet the requirement, the baffle of the air outlet corresponding to the second air supply port 22 is controlled to be adjusted (switched to the first state), so that the cold air in the fan chamber 41 can flow through this air outlet to the second air supply port 22, and finally be sent into the freezer compartment for refrigeration. When the temperature of the freezer compartment corresponding to the second air supply port 22 meets the requirement, the baffle of the air outlet corresponding to the second air supply port 22 is controlled to be switched to the second state. At this time, the cold air in the fan chamber 41 is not sent into the freezer compartment through the second air supply port 22, thereby reducing the energy consumption of the refrigeration equipment.

[0038] When the baffle is in the first state, the baffle can adjust the flow area of ​​the air outlet.

[0039] The cross-section of the fan chamber 41 is circular, and the central angle corresponding to the arc formed by each air outlet on the circle ranges from 0° to 20°. At this time, the rotation range of the baffle is from 0° to 45°, thereby ensuring the complete closure and opening of the air outlet.

[0040] The air duct assembly includes a driving member, the driving member is connected to the baffle in a one-to-one correspondence, and each of the driving members can drive the corresponding baffle to switch between the first state and the second state. The baffle is driven by the driving member to move, thereby ensuring automatic adjustment of the baffle to the air outlet.

[0041] As an embodiment, the air outlet includes a first air outlet 61 and a second air outlet 62, the baffle includes a first baffle 71 and a second baffle 72, the air outlet direction of the first air outlet 61 points to the first air supply outlet 21, the air outlet direction of the second air outlet 62 points to the second air supply outlet 22, the first baffle 71 can open or close the first air outlet 61, the second baffle 72 can open or close the second air outlet 62, and the first baffle 71 and / or the second baffle 72 are connected to the driving member. Figure 3 As shown, the first baffle 71 and the second baffle 72 are both connected to the same driving member. At this time, the driving member can simultaneously drive the first baffles 71 and 72 to move. When the temperature of the freezer compartment corresponding to the first air supply port 21 does not meet the requirement, the first baffle 71 is controlled to switch the first air port 61 to the first state, so that the cold air in the fan cavity 41 can flow to the first air supply port 21 through the first air port 61, and finally be sent into the freezer compartment for refrigeration. When the temperature of the freezer compartment corresponding to the first air supply port 21 meets the requirement, the first baffle 71 is switched to the second state. At this time, the cold air in the fan cavity 41 is not sent into the freezer compartment through the first air supply port 21, thereby reducing the energy consumption of the refrigeration equipment. Similarly, when the temperature of the freezer compartment corresponding to the second air supply port 22 does not meet the requirement, the second baffle 72 is controlled to switch to the first state, so that the cold air in the fan chamber 41 can flow to the second air supply port 22 through the second air port 62, and finally be sent into the freezer compartment for refrigeration. When the temperature of the freezer compartment corresponding to the second air supply port 22 meets the requirement, the second baffle 72 is controlled to switch to the second state. At this time, the cold air in the fan chamber 41 is not sent into the freezer compartment through the second air supply port 22, thereby reducing the energy consumption of the refrigeration equipment.

[0042] Optionally, the first baffle 71 and the second baffle 72 form a baffle, which can move in the fan chamber 41 and can open or close the first air outlet 61 and the second air outlet 62 separately. Figure 4 As shown in the figure, the baffle simultaneously closes the first air outlet 61 and the second air outlet 62. Figure 5 As shown in the figure, the baffle opens the first air outlet 61 and the second air outlet 62 at the same time. Of course, the baffle can also only close the first air outlet 61 and open the second air outlet 62, or only close the second air outlet 62 and open the first air outlet 61.

[0043] The air supply duct 42 has a contraction section 43, the first air outlet 61 is located between the contraction section 43 and the first air supply duct 21, and the second air outlet 62 is located between the contraction section 43 and the second air supply duct 22. The contraction section 43 means that the flow area of ​​the air supply duct 42 at this part becomes smaller. At this time, the contraction section 43 can not only meet the mutual connection of the parts of the air supply duct 42 on both sides of the contraction section 43, but also impose certain restrictions on the air outlet of the first air outlet 61 and the air outlet of the second air outlet 62, so as to promote the air outlet of the first air outlet 61 to flow to the first air supply duct 21 as much as possible, and also promote the air outlet of the second air outlet 62 to flow to the second air supply duct 22 as much as possible, thereby increasing the ability to adjust the air volume of the first air supply duct 21 and the air volume of the second air supply duct 22, and improving the adjustment effect on the corresponding compartment of the refrigeration equipment.

[0044] Specifically, the air duct panel 2 constitutes a side panel of the storage compartment, the first air supply port 21 is located at the upper half of the storage compartment, and the second air supply port 22 is located at the lower half of the storage compartment. At this time, the cold air sent in by the first air supply port 21 is used to cool the upper half of the storage compartment first, while the cold air sent in by the second air supply port 22 is used to cool the lower half of the storage compartment first. By adjusting the air supply volume of the first air supply port and the air supply volume of the second air supply port 22, the temperature difference between the upper and lower parts of the storage compartment is reduced as much as possible, thereby improving the storage reliability of the storage compartment. When the temperature of the upper half of the storage compartment is too high, the first baffle 71 is adjusted to increase the air volume of the first air outlet 61, thereby increasing the air volume of the first air supply outlet 21, thereby improving the cooling effect on the upper half of the storage compartment. The second baffle 72 can remain unchanged, or it can be switched to the second state so that the cold air in the fan chamber 41 is supplied through the first air supply outlet 21 to the maximum extent, so that the upper and lower temperatures of the storage compartment are balanced, the temperature difference is reduced, and the purpose of accurately controlling the temperature of the storage compartment is achieved.

[0045] The air duct assembly also includes a temperature detection mechanism, which can obtain the upper and lower temperatures of the storage compartment, and can control the working state of the baffle according to the upper and lower temperatures of the storage compartment. By distributing the temperature detection mechanism, the temperature distribution of the storage compartment can be judged, and then the first baffle 71 and the second baffle 72 can be controlled according to the temperature distribution, thereby achieving reliable control of the temperature distribution in the storage compartment.

[0046] The air duct assembly is arranged in a refrigeration device, and the refrigeration device has a defrost mode. When the refrigeration device is in the defrost mode, all the baffles are in the second state. Since the refrigeration device is in the defrost mode, there will be hot air in the fan chamber 41. At this time, the baffle is switched to the second state to prevent the hot air from entering the storage room and causing the temperature of the storage room to rise, thereby ensuring the storage reliability of the storage room.

[0047] When the refrigeration device ends the defrost mode, all the baffles are in the first state. At this time, the refrigeration device will quickly enter the refrigeration mode, and the gas in the fan chamber 41 is cold air. At this time, all the baffles are switched to the first state, so that the cold air quickly enters the storage room for refrigeration, so that the temperature of the storage room quickly reaches the set requirement, and then the state of the baffle can be dynamically adjusted according to the temperature distribution in the storage room.

[0048] When the refrigeration equipment is switched to the shutdown state, the compressor stops, the fan motor 51 stops working, and the cold air circulation stops. At this time, if the baffle and the corresponding air outlet are not completely closed, the corresponding driving component is controlled to work and the baffle is switched to the second state.

[0049] The number of the air supply ducts 42 is at least two, all of the air supply ducts 42 are connected to the fan cavity 41, and each of the air supply ducts 42 is connected to the fan cavity 41 through at least two air outlets. The ability of cold air to be delivered into the storage room is increased by using a plurality of air supply ducts 42, thereby improving the refrigeration effect on the storage room. The air supply ducts 42 and the storage rooms can also correspond one to one, thereby realizing the control of the refrigeration capacity of different storage rooms, and further improving the storage effect of the refrigeration equipment.

[0050] The air duct assembly also includes a fan structure, which includes a fan motor 51, a first drive structure 52 and a second drive structure 53. The fan structure is arranged in the fan cavity 41, the first drive structure 52 constitutes one of the drive members, and the second drive structure 53 constitutes another of the drive members. That is, the fan structure is a three-motor structure, wherein the fan motor 51 can drive the fan blades to rotate to drive the cold air, and the first drive structure 52 and the second drive structure 53 respectively adjust the baffles corresponding to the air outlets on different air supply ducts 42, which can reduce the space occupied by the drive members and ensure the reliable adjustment of the baffles.

[0051] Preferably, the rotating shaft of the fan motor 51, the driving shaft of the first driving structure 52 and the driving shaft of the second driving structure 53 are coaxially arranged, which is convenient for arranging the first driving structure 52 and the second driving structure 53, avoiding interference between the baffle and the fan blades, and ensuring the structural reliability of the fan structure.

[0052] Optionally, the first driving structure 52 is located on one side of the fan motor 51 , and the second driving structure 53 is located on the other side of the fan motor 51 .

[0053] The first driving structure 52 can drive the corresponding baffle to rotate clockwise, and the second driving structure can drive the corresponding baffle to rotate counterclockwise, thereby realizing independent adjustment of the baffles on the air supply duct 42 without any interference between the baffles on the two air supply ducts 42.

[0054] A refrigeration device comprises the above-mentioned air duct assembly.

[0055] The refrigeration device includes a freezing chamber, the air duct panel 2 constitutes a side panel of the freezing chamber, and the first air supply port 21 and the second air supply port 22 are distributed along the height direction of the refrigeration device.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
