Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of refrigeration equipment, and specifically provides a wind-cooled refrigerator. BACKGROUND

[0002] The wind-cooled refrigerator mainly comprises a storage chamber, an evaporator and an evaporative fan. The storage chamber is used for placing stored materials such as foodstuffs, the evaporator is used for cooling the air around it, and the evaporative fan is used for delivering the air cooled by the evaporator to the storage chamber and blowing it to the foodstuffs in the storage chamber.

[0003] When the user freezes / chills the foodstuffs, it is often desired that the foodstuffs can be preserved as much as possible. This requires that the foodstuffs can be rapidly cooled, so as to achieve the effect of freezing / chilling the foodstuffs, and that the water loss of the foodstuffs is as little as possible, so as to achieve the effect of preserving the foodstuffs. However, when the foodstuffs are rapidly frozen / chilled, the cold air blown to the foodstuffs has a large flow rate, which can take away a large amount of water on the foodstuffs and reduce the water content of the foodstuffs. In order to reduce the water loss of the foodstuffs, it is necessary to reduce the flow rate of the air, which cannot achieve the effect of rapidly freezing the foodstuffs.

[0004] Meanwhile, when the refrigerator defrosts the evaporator, in order to ensure the preservation effect of the foodstuffs, it is also necessary to avoid the hot air from entering the storage chamber, so as to avoid the temperature rise of the foodstuffs.

[0005] Therefore, there is an urgent need for a new wind-cooled refrigerator to ensure the freshness of the foodstuffs. SUMMARY

[0043] Before that, it needs to be explained that, for the convenience of description, and in order to enable those skilled in the art to quickly understand the technical solutions of the present application, only the technical features which are closely related (directly related or indirectly related) to the technical problems and / or technical concepts to be solved by the present application are described hereinafter, and the technical features which are weakly related to the technical problems and / or technical concepts to be solved by the present application are not described. Since the technical features which are weakly related belong to the common knowledge in the art, the disclosure of the present application will not be insufficient even if the weakly related features are not described.

[0044] As shown in Figure 1 and Figure 2 , in some embodiments of the present application, the refrigerator comprises a cabinet 1, an evaporator 2, an air duct cover plate 3 and an air fan 4. Among them, the cabinet 1 defines a storage chamber 11, a supply air duct 12 and a refrigeration chamber 13 which are sequentially communicated, the evaporator 2 is installed in the refrigeration chamber 13, the air duct cover plate 3 is arranged between the supply air duct 12 and the storage chamber 11, and the air fan 4 is installed on the air duct cover plate 3.

[0045] In some embodiments of the present application, when the refrigerator is working, the evaporator 2 cools the air in the refrigeration chamber 13. The air cooled by the evaporator 2 flows through the supply air duct 12 and the storage chamber 11 in turn under the driving of the air fan 4, and finally flows back into the refrigeration chamber 13.

[0046] In addition, those skilled in the art can also omit the setting of the refrigeration chamber 13 and set the evaporator 2 in the supply air duct 12 according to the needs in other embodiments of the present application.

[0047] Further, although Figure 1 and Figure 2 have two inner containers (for defining the storage chamber 11) in the refrigerator, and each inner container is respectively provided with an air duct cover plate 3 and an air fan 4, in other embodiments of the present application, those skilled in the art can also provide the refrigerator with other number of inner containers according to the needs, such as one, three, four, etc. When the refrigerator has at least two inner containers, those skilled in the art can also make at least part of all the inner containers share the air duct cover plate 3 and the air fan 4 according to the needs.

[0048] As shown in Figures 3 to 6.3As shown, the air duct cover plate 3 comprises 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 arranged 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, so that 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 compartment 11 are sequentially communicated.

[0049] Although not shown in the drawings, in some embodiments of the present application, the fan 4 is installed in the air inlet cavity 33, and specifically, at least a part of the fan 4 is located in the air inlet cavity 33. Preferably, the fan 4 is a centrifugal fan. Alternatively, in other embodiments of the present application, those skilled in the art can also set the fan 4 as any other feasible fan according to the needs, such as an axial fan or a cross-flow fan.

[0050] Of course, in other embodiments of the present application, those skilled in the art can also install the fan 4 at any other feasible position according to the needs, such as installing the fan 4 in the air supply air duct 12 or the refrigeration compartment 13, and fixing the fan 4 to the cabinet 1 or to the air duct cover plate 3.

[0051] As shown in Figure 4 , Figures 6.1 to 6.3 , the air outlet 32 is arranged on the side of the air duct cover plate 3 facing the storage compartment 11, and the air outlet 32 comprises a direct blowing air outlet 321 and a side blowing air outlet 322. Among them, the direct blowing air outlet 321 is used to blow cold air directly to the middle part of the storage compartment 11, so as to blow cold air directly to the food materials in the storage compartment 11, so as to quickly cool the food materials. The side blowing air outlet 322 is used to blow cold air to the side wall or side of the storage compartment 11, so as to avoid blowing cold air directly to the food materials in the storage compartment 11, so as to avoid the cold air taking away the moisture on the food materials.

[0052] Continuing to refer to Figure 4 , Figures 6.1 to 6.3 , the direct blowing air outlet 321 and the side blowing air outlet 322 are respectively multiple, and the direct blowing air outlet 321 is mainly distributed in the middle part of the air duct cover plate 3, and the side blowing air outlet 322 is mainly distributed on the left and right sides of the air duct cover plate 3. In addition, those skilled in the art can also make appropriate adjustments to the distribution of the direct blowing air outlet 321 and the side blowing air outlet 322 according to the needs, such as distributing the side blowing air outlet 322 on the upper side of the air duct cover plate 3.

[0053] Optionally, in order to avoid the straight-blowing air outlet 321 directly blowing the food materials in the storage chamber 11, a baffle (not shown in the figure) can also be arranged at the straight-blowing air outlet 321. Specifically, the baffle protrudes from the one side of the cover plate body 31 close to the storage chamber 11. Further optionally, in order to slow down the air speed at the side-blowing air outlet 322, a grille (not shown in the figure) can also be arranged at the side-blowing air outlet 322, so as to divide the air flow blown out from the side-blowing air outlet 322 into multiple air flows, thereby reducing the flow rate of a single air flow.

[0054] As shown in Figures 6.1 to 6.3 , the air inlet 34 includes a straight-blowing air inlet 341 and a side-blowing air inlet 342, wherein the straight-blowing air inlet 341 corresponds to the straight-blowing air outlet 321, and the side-blowing air inlet 342 corresponds to the side-blowing air outlet 322. Further, the straight-blowing air inlet 341 and the side-blowing air inlet 342 are both formed on the side wall of the air inlet cavity 33. Preferably, the straight-blowing air inlet 341 and the side-blowing air inlet 342 are both two, 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, those skilled in the art can also arrange the two side-blowing air inlets 342 and the straight-blowing air inlet 341 into other any feasible distribution forms according to the needs, for example, arranging the straight-blowing air inlet 341 as one and the side-blowing air inlet 342 as two, and arranging the one straight-blowing air inlet 341 and the two side-blowing air inlets 342 in triangular distribution.

[0055] Continuing to refer to Figures 6.1 to 6.3 , the cover plate air duct 35 includes a straight-blowing air duct 351 and a side-blowing air duct 352, wherein the straight-blowing air duct 351 communicates with the straight-blowing air outlet 321 and the straight-blowing air inlet 341 respectively, and the side-blowing air duct 352 communicates with the side-blowing air outlet 322 and the side-blowing air inlet 342 respectively. Further, the straight-blowing air duct 351 and the side-blowing air duct 352 are both two, and the two straight-blowing air ducts 351 are oppositely arranged on the upper and lower sides of the air inlet cavity 33, the two side-blowing air ducts 352 are oppositely arranged on the left and right sides of the air inlet cavity 33, and the two side-blowing air ducts 352 are oppositely arranged on the left and right sides of the straight-blowing air duct 351.

[0056] Continuing to refer to Figures 6.1 to 6.3 , in some embodiments of the present application, the refrigerator further comprises a damper device 5 for controlling the blowing of cold air from the straight-blowing air outlet 321 and / or the side-blowing air outlet 322.

[0057] As shown in Figures 6.1 to 7As shown, the damper device 5 comprises a first damper 51, a second damper 52 and a motor 53. Specifically, the housing of the motor 53 is fixedly connected with the cover plate body 31, and the motor 53 is optionally installed in the air inlet cavity 33. The rotating shaft of the motor 53 is fixedly connected with the first damper 51 and the second damper 52 through a cantilever (not labeled in the figure) to drive the first damper 51 and the second damper 52 to rotate.

[0058] From Figures 6.1 to 7 It can be seen that the first damper 51 and the second damper 52 are both arc-shaped plate structures, and the first damper 51 and the second damper 52 coincide with their own rotation tracks. Moreover, the first damper 51 corresponds to one straight blowing air inlet 341 and one side blowing air inlet 342, and the second damper 52 also corresponds to one straight blowing air inlet 341 and one side blowing air inlet 342. In other words, the first damper 51 and the second damper 52 can respectively control the opening and closing of one straight blowing air inlet 341 and one side blowing air inlet 342.

[0059] As Figure 6.1 shown, the motor 53 drives the first damper 51 to move to a first position of opening the straight blowing air inlet 341 and shielding the left side blowing air inlet 342, and the motor 53 drives the second damper 51 to move to a first position of opening the straight blowing air inlet 341 and shielding the right side blowing air inlet 342. In Figure 6.1 the state shown, the cold air in the air supply duct 12 flows through the air inlet cavity 33, the straight blowing air inlet 341, the straight blowing air duct 351 and the straight blowing air outlet 321 in sequence, and finally enters the storage compartment 11.

[0060] As Figure 6.2 shown, the motor 53 drives the first damper 51 to move to a second position of shielding the upper straight blowing air inlet 341 and opening the left side blowing air inlet 342, and the motor 53 drives the second damper 51 to move to a second position of shielding the lower straight blowing air inlet 341 and opening the right side blowing air inlet 342. In Figure 6.2 the state shown, the cold air in the air supply duct 12 flows through the air inlet cavity 33, the side blowing air inlet 342, the side blowing air duct 352 and the side blowing air outlet 322 in sequence, and finally enters the storage compartment 11.

[0061] As Figure 6.2 shown, the motor 53 drives the first damper 51 to move to a third position of shielding the lower straight blowing air inlet 341 and the left side blowing air inlet 342, and the motor 53 drives the second damper 51 to move to a third position of shielding the upper straight blowing air inlet 341 and the right side blowing air inlet 342. In Figure 6.3In the state shown, since the direct blowing air inlet 341 and the left side blowing air inlet 342 are both shielded, the air in the air supply duct 12 cannot flow into the storage compartment 11. At this time, the evaporator 2 can be defrosted, and the hot air generated during the defrosting of the evaporator 2 cannot flow into the storage compartment 11 due to the shielding of the direct blowing air inlet 341 and the left side blowing air inlet 342.

[0062] Further, although not shown in the figure, in some embodiments of the present application, the refrigerator further comprises a temperature sensor for detecting the temperature of the storage compartment 11.

[0063] The working principle of the damper device 5 will be described in detail below. Figures 6.1 to 6.3

[0064] When the first damper 51 and the second damper 52 are in the first position (as shown in FIG. 1) and the temperature sensor detects that the temperature in the storage compartment 11 has dropped to a first preset temperature, it indicates that the rapid cooling of the food in the refrigerator has ended, and the motor 53 is rotated forward to move the first damper 51 and the second damper 52 in the air supply duct 12 in the clockwise direction to the second position (as shown in FIG. 2). Figure 6.1 Figure 6.1 Figure 6.2

[0065] When the first damper 51 and the second damper 52 are in the second position (as shown in FIG. 2) and the temperature sensor detects that the temperature in the storage compartment 11 has risen to a second preset temperature, it indicates that the temperature in the storage compartment 11 is high and rapid cooling is needed, and the motor 53 is reversed to move the first damper 51 and the second damper 52 in the air supply duct 12 in the counterclockwise direction to the first position (as shown in FIG. 1). Figure 6.2 Figure 6.2 Figure 6.1

[0066] When defrosting of the evaporator 2 is needed, the motor 53 drives the first damper 51 and the second damper 52 to move to the position shown in FIG. 3, so as to shield the direct blowing air inlet 341 and the side blowing air inlet 342 at the same time. Figure 6.3

[0067] 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.

[0068] ​​​​​​​​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 food, but also improves the cooling speed of the food, thereby improving the preservation effect of the food. At the same time, it also avoids the hot air generated during the defrosting process of the evaporator 2 from entering the storage compartment 11 and affecting the preservation of the food.

The first spring 57 has two ends respectively connected with the first air door 51 and the cover plate body 31, and the first spring 57 is used to provide a force away from the motor 53 for the first air door 51. The second spring 58 has two ends respectively connected with the second air door 52 and the cover plate body 31, and the second spring 58 is used to provide a force away from the motor 53 for the second air door 52. The plurality of pulleys 59 are used to support the first cable 55 and the second cable 56.
