[0044] In some embodiments of the present application, when the refrigerator is working, the evaporator 2 cools the air in the refrigeration chamber 13, and the air cooled by the evaporator 2 flows through the supply air duct 12 and the storage chamber 11 in sequence under the driving of the fan 4, and finally flows back into the refrigeration chamber 13.

[0045] In addition, the skilled in the art can also omit the setting of the refrigeration chamber 13 and set the evaporator 2 in the air supply air duct 12 in other embodiments of the present application as needed.

[0046] Further, although Figure 1 and Figure 2 have two inner containers (for defining the storage chamber 11) in the refrigerator, and each of the inner containers is respectively provided with the air duct cover plate 3 and the air fan 4, the skilled in the art can also provide the refrigerator with other number of inner containers, such as one, three, four, etc. as needed in other embodiments of the present application. When the refrigerator has at least two inner containers, the skilled in the art can also share at least part of all the inner containers with the air duct cover plate 3 and the air fan 4 as needed.

[0047] As shown in Figures 3 to 7 , the air duct cover plate 3 includes a cover plate body 31, an air outlet 32, an air inlet cavity 33, an air inlet 34, and a cover plate air duct 35. The air outlet 32, the air inlet cavity 33, the air inlet 34, and the cover plate air duct 35 are all provided on the cover plate body 31, and the air inlet cavity 33, the air inlet 34, the cover plate air duct 35, and the air outlet 32 are sequentially communicated to sequentially communicate the air supply air duct 12, the air inlet cavity 33, the air inlet 34, the cover plate air duct 35, the air outlet 32, and the storage chamber 11.

[0048] Although not shown in the figure, in some embodiments of the present application, the air fan 4 is installed in the air inlet cavity 33, specifically, at least part of the air fan 4 is located in the air inlet cavity 33. Preferably, the air fan 4 is a centrifugal fan. Alternatively, the skilled in the art can also set the air fan 4 as any other feasible air fan, such as an axial fan or a cross-flow fan, as needed in other embodiments of the present application.

[0049] Of course, the skilled in the art can also install the air fan 4 at any other feasible position as needed in other embodiments of the present application, for example, install the air fan 4 in the air supply air duct 12 or the refrigeration chamber 13, and fix the air fan 4 to the cabinet 1 or to the air duct cover plate 3.

[0050] As shown in Figure 4 , Figure 6 and Figure 7 , the air outlet 32 is provided on the side of the air duct cover plate 3 facing the storage chamber 11, and the air outlet 32 includes a direct blowing air outlet 321 and a side blowing air outlet 322. Among them, the direct blowing air outlet 321 is used to directly blow cold air to the middle part of the storage chamber 11, so as to directly blow cold air to the food materials in the storage chamber 11, thereby quickly cooling the food materials. The side blowing air outlet 322 is used to blow cold air to the side wall or side part of the storage chamber 11, so as to avoid directly blowing cold air to the food materials in the storage chamber 11, so as to avoid the cold air taking away the moisture on the food materials.

[0051] With reference to Figure 4 , Figure 6 and Figure 7 continuously, the straight blowing air outlets 321 and the side blowing air outlets 322 are multiple respectively, and the straight blowing air outlets 321 are mainly distributed in the middle part of the air duct cover plate 3, and the side blowing air outlets 322 are mainly distributed on the left and right sides of the air duct cover plate 3. In addition, the skilled in the art can also make appropriate adjustments to the distribution of the straight blowing air outlets 321 and the side blowing air outlets 322 as needed, for example, to make the side blowing air outlets 322 distributed on the upper side of the air duct cover plate 3.

[0052] Optionally, in order to avoid the straight blowing air outlets 321 directly blowing the food materials in the storage room 11, a wind baffle (not shown in the figure) can also be provided at the straight blowing air outlets 321. Specifically, the wind baffle protrudes from the side of the cover plate body 31 close to the storage room 11. Further optionally, in order to slow down the wind speed at the side blowing air outlets 322, a grille (not shown in the figure) can also be provided at the side blowing air outlets 322, so as to divide the airflow blown out from the side blowing air outlets 322 into multiple streams through the grille, thereby reducing the flow rate of a single stream of airflow.

[0053] As shown in Figure 6 and Figure 7 , the air inlet 34 includes straight blowing air inlets 341 and side blowing air inlets 342, wherein the straight blowing air inlets 341 correspond to the straight blowing air outlets 321, and the side blowing air inlets 342 correspond to the side blowing air outlets 322. Further, the straight blowing air inlets 341 and the side blowing air inlets 342 are both formed on the side wall of the air inlet cavity 33. Preferably, the straight blowing air inlets 341 and the side blowing air inlets 342 are two respectively, and the two straight blowing air inlets 341 and the two side blowing air inlets 342 are in quadrangular cross distribution. Specifically, the two straight blowing air inlets 341 are oppositely arranged on the upper and lower sides of the air inlet cavity 33, and the two side blowing air inlets 342 are oppositely arranged on the left and right sides of the air inlet cavity 33. Alternatively, the skilled in the art can also arrange the two side blowing air inlets 342 and the straight blowing air inlets 341 into other any feasible distribution form as needed, for example, to arrange the straight blowing air inlets 341 as one and the side blowing air inlets 342 as two, and to make the one straight blowing air inlet 341 and the two side blowing air inlets 342 in triangular distribution.

[0054] With reference to Figure 6 and Figure 7The cover plate air duct 35 includes a direct-blowing air duct 351 and a side-blowing air duct 352. The direct-blowing air duct 351 is connected to the direct-blowing air outlet 321 and the direct-blowing air inlet 341, respectively, and the side-blowing air duct 352 is connected to the side-blowing air outlet 322 and the side-blowing air inlet 342, respectively. Furthermore, there are two direct-blowing air ducts 351 and two side-blowing air ducts 352. The two direct-blowing air ducts 351 are arranged opposite each other on the upper and lower sides of the air inlet cavity 33, and the two side-blowing air ducts 352 are arranged opposite each other on the left and right sides of the air inlet cavity 33, and opposite each other on the left and right sides of the direct-blowing air duct 351.

[0055] Continue reading Figure 6 and Figure 7 In some embodiments of the present invention, the refrigerator further includes a damper device 5 for controlling cold air to be blown out from the direct air outlet 321 and / or the side air outlet 322.

[0056] like Figures 6 to 8 As shown, the damper device 5 includes a first damper 51, a second damper 52, and a motor 53 as a drive device. Specifically, the housing of the motor 53 is fixedly connected to the cover plate body 31. Optionally, the motor 53 is also installed in the air inlet chamber 33. The rotating shaft of the motor 53 is fixedly connected to the first damper 51 and the second damper 52 respectively via a cantilever (not marked in the figure) to drive the first damper 51 and the second damper 52 to rotate.

[0057] from Figures 6 to 8 As can be seen, both the first damper 51 and the second damper 52 are arc-shaped plate structures, and their rotation trajectories coincide. Furthermore, the first damper 51 corresponds to one direct air inlet 341 and one side air inlet 342, and the second damper 52 also corresponds to one direct air inlet 341 and one side air inlet 342. In other words, the first damper 51 and the second damper 52 can be moved to a first position that opens the two direct air inlets 341 and blocks the two side air inlets 342 (e.g., ...). Figure 6 As shown), the first damper 51 and the second damper 52 can also be moved to a second position that blocks the two direct air inlets 341 and opens the two side air inlets 342 (as shown). Figure 7 (As shown).

[0058] Furthermore, although not shown in the figures, in some embodiments of the present invention, the refrigerator also includes a temperature sensor for detecting the temperature of the storage compartment 11.

[0059] under Figures 6 to 8 The working principle of the damper device 5 will be explained in detail below.

[0060] When the first damper 51 and the second damper 52 are in the first position (e.g.) Figure 6When the first air door 51 and the second air door 52 are located at the second position (as shown in FIG. 5B), and the temperature sensor detects that the temperature inside the storage compartment 11 decreases to a first preset temperature, it indicates that the rapid cooling of the foodstuff by the refrigerator is completed, the motor 53 is reversed to move the first air door 51 and the second air door 52 to the first position (as shown in FIG. 5A). Figure 7

[0061] When the first air door 51 and the second air door 52 are located at the first position (as shown in FIG. 5A), and the temperature sensor detects that the temperature inside the storage compartment 11 increases to a second preset temperature, it indicates that the temperature inside the storage compartment 11 is high, and the rapid cooling is needed, the motor 53 is reversed to move the first air door 51 and the second air door 52 to the second position (as shown in FIG. 5B). Figure 7 Figure 6

[0062] In some embodiments of the present application, the first preset temperature is lower than the second preset temperature. For example, the first preset temperature is 2℃, 3℃, 5℃, etc. lower than the second preset temperature.

[0063] Based on the foregoing description, those skilled in the art can understand that, in some embodiments of the present application, by providing the straight blowing air outlet 321 and the side blowing air outlet 322 on the air duct cover plate 3, and configuring the air door device 5 for the refrigerator to control the cold air to blow from the straight blowing air outlet 321 and / or the side blowing air outlet 322 to the storage compartment 11 through the air door device 5, the refrigerator of the present application not only reduces the loss of moisture of the foodstuff, but also improves the cooling speed of the foodstuff, thereby improving the preservation effect of the foodstuff.

The two ends of the first spring 57 are respectively connected with the first damper 51 and the cover body 31, and the first spring 57 is used to provide a force away from the motor 53 for the first damper 51. The two ends of the second spring 58 are respectively connected with the second damper 52 and the cover body 31, and the second spring 58 is used to provide a force away from the motor 53 for the second damper 52.

Since the first fixing ring 543 is aligned with the first recess 541, the first cable 55 will not come out of the first recess 541. The fixing of the second cable 56 is the same as that of the first cable 55, which will not be described here.
