Since the technical features with the weak degree of association belong to the common general knowledge in the field, the present invention does not cause insufficient disclosure of the present invention even if the features with the weak degree of association are not described.

As shown in fig. 1 and 2, in some embodiments of the present invention, a refrigerator includes a cabinet 1, an evaporator 2, a duct cover 3, and a fan 4. The refrigerator comprises a refrigerator body 1, an evaporator 2, an air supply duct 12, a refrigerating chamber 13, an air duct cover plate 3, a fan 4 and a storage chamber 11, wherein the storage chamber 11, the air supply duct 12 and the refrigerating chamber 13 are sequentially communicated with one another, the evaporator is installed in the refrigerating chamber 13, the air duct cover plate 3 is arranged between the air supply duct 12 and the storage chamber 11, and the fan 4 is installed on the air duct cover plate 3.

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

Furthermore, those skilled in the art may omit the cooling chamber 13 and dispose the evaporator 2 in the supply air duct 12 in other embodiments of the present invention, as necessary.

Further, although the refrigerator in fig. 1 and 2 has two inner containers (for defining the storage chamber 11) and each inner container is configured with the air duct cover plate 3 and the fan 4, in other embodiments of the present invention, a person skilled in the art may configure other numbers of inner containers, such as one, three, four, etc., for the refrigerator as needed. When the refrigerator has at least two inner containers, a person skilled in the art can also make at least one part of all the inner containers share the air duct cover plate 3 and the fan 4 according to the requirement.

As shown in fig. 3 to 6.3, the air duct cover 3 includes a cover body 31, an air outlet 32, an air inlet chamber 33, an air inlet 34, and a cover air duct 35. The air outlet 32, the air inlet chamber 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 chamber 33, the air inlet 34, the cover plate air duct 35 and the air outlet 32 are sequentially communicated, so that the air supply duct 12, the air inlet chamber 33, the air inlet 34, the cover plate air duct 35, the air outlet 32 and the storage chamber 11 are sequentially communicated.

Although not shown in the drawings, in some embodiments of the utility model, the fan 4 is mounted within the air intake cavity 33, and in particular, at least a portion of the fan 4 is located within the air intake cavity 33. Preferably, the fan 4 is a centrifugal fan. Alternatively, in other embodiments of the present invention, the fan 4 may be any other feasible fan, such as an axial fan or a cross-flow fan, as required by those skilled in the art.

Of course, in other embodiments of the present invention, the skilled person can install the fan 4 at any other feasible position, for example, the fan 4 is installed in the supply air duct 12 or the cooling chamber 13, and the fan 4 is fixed to the box body 1 or the duct cover plate 3.

As shown in fig. 4, 6.1 to 6.3, the air outlet 32 is disposed on a side of the duct cover 3 facing the storage compartment 11, and the air outlet 32 includes a blow-through air outlet 321 and a side-blow air outlet 322. The direct-blowing air outlet 321 is used for directly blowing cold air to the middle part of the storage chamber 11 so as to directly blow the cold air to the food materials in the storage chamber 11, thereby rapidly refrigerating the food materials. The side-blowing air outlet 322 is used for blowing cold air to the side wall or the side portion of the storage chamber 11 to prevent the cold air from directly blowing the food material in the storage chamber 11, so as to prevent the cold air from taking away moisture on the food material.

With reference to fig. 4, 6.1 to 6.3, the plurality of blow-through air outlets 321 and the plurality of side-blow air outlets 322 are respectively provided, the blow-through air outlets 321 are mainly distributed in the middle of the air duct cover plate 3, and the side-blow air outlets 322 are mainly distributed on the left and right sides of the air duct cover plate 3. Furthermore, those skilled in the art can also make appropriate adjustments to the distribution of the straight air outlet 321 and the side air outlets 322, for example, to make the side air outlets 322 distributed on the upper side of the duct cover 3.

Optionally, in order to avoid the blow-through outlet 321 from blowing the food material in the storage chamber 11, a wind shield (not shown) may be disposed at the blow-through outlet 321. Specifically, the wind deflector protrudes from one surface of the cover body 31 close to the storage chamber 11. Further alternatively, in order to slow down the wind speed at the side blowing outlet 322, a grille (not shown in the figure) may be further disposed at the side blowing outlet 322, so as to divide the airflow blown out from the side blowing outlet 322 into a plurality of strands through the grille, thereby reducing the flow velocity of a single airflow.

As shown in fig. 6.1 to 6.3, the air inlet 34 includes a direct-blowing air inlet 341 and a side-blowing air inlet 342, wherein the direct-blowing air inlet 341 corresponds to the direct-blowing air outlet 321, and the side-blowing air inlet 342 corresponds to the side-blowing air outlet 322. Further, both the straight blow intake 341 and the side blow intake 342 are formed on the side wall of the intake chamber 33. Preferably, there are two direct-blowing air inlets 341 and two side-blowing air inlets 342, and the two direct-blowing air inlets 341 and the two side-blowing air inlets 342 are distributed in a quadrangular staggered manner. Specifically, two direct-blow air inlets 341 are oppositely disposed on the upper and lower sides of the air intake chamber 33, and two side-blow air inlets 342 are oppositely disposed on the left and right sides of the air intake chamber 33. Alternatively, one skilled in the art may set the two side blow inlets 342 and the straight blow inlets 341 in any other distribution manner as required, for example, set the straight blow inlets 341 to be one, set the side blow inlets 342 to be two, and make the one straight blow inlet 341 and the two side blow inlets 342 to be in a triangular distribution.

With continued reference to fig. 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 is respectively communicated with the straight-blowing air outlet 321 and the straight-blowing air inlet 341, and the side-blowing air duct 352 is respectively communicated with the side-blowing air outlet 322 and the side-blowing air inlet 342. Further, the straight-blow duct 351 and the side-blow duct 352 are two each, and the two straight-blow ducts 351 are disposed oppositely on the upper and lower sides of the air intake chamber 33, the two side-blow ducts 352 are disposed oppositely on the left and right sides of the air intake chamber 33, and the two side-blow ducts 352 are disposed oppositely on the left and right sides of the straight-blow duct 351.

With continued reference to fig. 6.1 to 6.3, in some embodiments of the present invention, the refrigerator further includes a damper device 5, and the damper device 5 is used for controlling the cool air to be blown out from the straight blow-out opening 321 and/or the side blow-out opening 322.

As shown in fig. 6.1 to 7, 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 to the cover plate body 31, and optionally, the motor 53 is also installed in the air intake chamber 33. The rotating shaft of the motor 53 is fixedly connected to the first damper 51 and the second damper 52 through a cantilever (not labeled) respectively, so as to drive the first damper 51 and the second damper 52 to rotate.

As can be seen from fig. 6.1 to 7, the first damper 51 and the second damper 52 are both arc-shaped plate-shaped structures, and the first damper 51 and the second damper 52 are coincident with their own rotation tracks. The first damper 51 corresponds to one of the straight blow inlets 341 and one of the side blow inlets 342, and the second damper 52 corresponds to one of the straight blow inlets 341 and one of the side blow inlets 342. In other words, the first damper 51 and the second damper 52 can control the opening and closing of one of the straight blow inlets 341 and one of the side blow inlets 342, respectively.

As shown in fig. 6.1, the motor 53 drives the first damper 51 to move to the first position for opening the blow-through port 341 and shielding the left-side blow-through port 342; the motor 53 drives the second damper 51 to move to the first position where the blow-through ports 341 are opened and the right side blow-through ports 342 are shielded. In the state shown in fig. 6.1, the cool air in the air supply duct 12 flows through the air inlet chamber 33, the direct-blowing inlet 341, the direct-blowing air duct 351 and the direct-blowing outlet 321 in sequence, and finally enters the storage chamber 11.

As shown in fig. 6.2, the motor 53 drives the first damper 51 to move to the second position for shielding the upper blow-through port 341 and opening the left-side blow-through port 342; the motor 53 drives the second damper 51 to move to a second position where it shields the lower direct-blowing inlet 341 and opens the right-side blowing inlet 342. In the state shown in fig. 6.2, the cool air in the supply air duct 12 flows through the air inlet chamber 33, the side blowing inlet 342, the side blowing duct 352 and the side blowing outlet 322 in sequence, and finally enters the storage chamber 11.

As shown in fig. 6.2, the motor 53 drives the first damper 51 to move to the third position for shielding the lower direct-blowing inlet 341 and the left-side blowing inlet 342; the motor 53 drives the second damper 51 to move to the third position where the upper blow-through ports 341 and the right-side blow-through ports 342 are shielded. In the state shown in fig. 6.3, since both the blow-through inlet 341 and the left-side blow-in inlet 342 are shielded, the air in the supply air duct 12 does not flow into the storage chamber 11. At this time, the evaporator 2 can be defrosted, and the hot air generated during defrosting of the evaporator 2 is shielded by both the direct-blowing inlet 341 and the left-side blowing inlet 342 and does not flow into the storage chamber 11.

Further, although not shown in the drawings, in some embodiments of the present invention, the refrigerator further includes a temperature sensor for detecting the temperature of the storage chamber 11.

The operating principle of the damper arrangement 5 is explained in more detail below with reference to fig. 6.1 to 6.3.

When the first damper 51 and the second damper 52 are located at the first position (as shown in fig. 6.1), and the temperature sensor detects that the temperature in the storage chamber 11 is reduced to the first preset temperature, indicating that the rapid cooling of the food material by the refrigerator is finished, the motor 53 is rotated forward, so that the first damper 51 and the second damper 52 in fig. 6.1 are moved to the second position (as shown in fig. 6.2) in the clockwise direction.

When the first and second dampers 51 and 52 are in the second position (as shown in fig. 6.2) and the temperature sensor detects that the temperature in the storage compartment 11 has risen to the second preset temperature, indicating that the temperature in the storage compartment 11 is high, rapid cooling is required, the motor 53 is reversed to move the first and second dampers 51 and 52 in fig. 6.2 in the counterclockwise direction to the first position (as shown in fig. 6.1).

When defrosting of the evaporator 2 is required, the motor 53 is caused to drive the first and second dampers 51 and 52 to move to the positions shown in fig. 6.3 to shield the direct-blowing inlet 341 and the side-blowing inlet 342 at the same time.

Wherein the first preset temperature is lower than the second preset temperature. For example, the first predetermined temperature is 2 ℃, 3 ℃, 5 ℃ or the like lower than the second predetermined temperature.

Based on the foregoing description, it can be understood by those skilled in the art that, in some embodiments of the present invention, the air duct cover plate 3 is provided with the straight air-blowing outlet 321 and the side air-blowing outlet 322, and the air door device 5 is configured for the refrigerator, so as to control cold air to blow from the straight air-blowing outlet 321 and/or the side air-blowing outlet 322 to the storage chamber 11 through the air door device 5, so that the refrigerator of the present invention not only reduces the loss of moisture in the food material, but also increases the cooling speed of the food material, thereby improving the fresh-keeping effect of the food material. Meanwhile, hot air generated in the defrosting process of the evaporator 2 is prevented from entering the storage chamber 11, and the influence on the fresh keeping of food materials is avoided.

One end of the swing link 54 is fixedly connected with the rotating shaft of the motor 53, and the other end of the swing link 54 is fixedly connected with the first cable 55 and the second cable 56 respectively. One end of the first cable 55 far away from the rotating shaft of the motor 53 is fixedly connected with the first air door 51, and one end of the second cable 56 far away from the rotating shaft of the motor 53 is fixedly connected with the second air door 52. Both ends of the first spring 57 are connected to the first damper 51 and the cover body 31, respectively, and the first spring 57 is used to provide a force to the first damper 51 away from the motor 53. Both ends of the second spring 58 are connected to the second damper 52 and the cover body 31, respectively, and the second spring 58 is used to provide a force to the second damper 52 away from the motor 53. The pulley 59 is plural and is used to support the first cable 55 and the second cable 56.

As shown in fig. 9, an end of the swing link 54 away from the motor 53 has an arc-shaped surface (not labeled), and the swing link 54 is further provided with a first sinking groove 541 and a second sinking groove 542 located on the arc-shaped surface. The first sinking groove 541 is used for clamping the first cable 55, and the second sinking groove 542 is used for clamping the second cable 56. The swing link 54 is further provided with a first fixing ring 543 for fixing the first cable 55 and a second fixing ring 544 for fixing the second cable 56, and the first fixing ring 543 is aligned with the first sinking groove 541 and the second fixing ring 544 is aligned with the second sinking groove 542.

As shown in fig. 8 and 10, one end of the first cable 55 is bolted to the first damper 51, the other end of the first cable 55 is bolted to the first fixing ring 543, and a portion of the first cable 55 is caught in the first sinking groove 541. Since the first fixing ring 543 is aligned with the first sinking groove 541, the first cable 55 does not fall out of the first sinking groove 541. The second cable 56 is fixed in the same manner as the first cable 55, and will not be described in detail.

The operation of the damper device 5 in other embodiments of the present invention will now be briefly described with reference to fig. 8 and 10.
