Detailed Description
In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as viewed with reference to the accompanying drawings, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves.
According to an aspect of the present invention, an air supply assembly is provided, wherein the air supply assembly includes a plurality of directional air supply ducts 20, at least two directional air supply ducts 20 are communicated with each other through a confluence air duct 50, and a flow direction control switch 60 for controlling a flow path of air flow in the directional air supply duct 20 is disposed at a connection between at least one directional air supply duct 20 and the confluence air duct 50.
The air supply duct of the present invention can realize different air supply modes through the flow direction control switch 60: air is supplied to corresponding areas through the directional air supply ducts 20; and concentrates the wind of the directional wind supply duct 20 communicated with the merging wind duct 50 through the merging wind duct 50 to realize the concentrated wind supply. The flow direction control switch 60 is at least configured to selectively allow the air flow to flow through the collecting air duct 50 or continue to flow along the directional supply air duct 20. Taking two directional air supply ducts 20 communicated with each other through the collecting duct 50 as an example, the flow direction control switch 60 can selectively supply air to two corresponding regions through the two directional air supply ducts 20 or concentrate the air direction of the two directional air supply ducts 20 to one of the regions corresponding to the directional air supply ducts 20.
In addition, in order to collect the air from any one of the two directional air supply ducts 20 in the area corresponding to the directional air supply duct 20, flow direction control switches 60 may be respectively disposed on the two directional air supply ducts 20, and the two directional air supply ducts 20 may be communicated with each other through the two collecting ducts 50. For ease of arrangement, the two flow direction control switches 60 may be disposed at different heights. In the illustrated embodiment, a flow direction control switch 60 is provided on only one directional supply air duct 20.
The air supply assembly of the present invention may include more than two directional air supply ducts 20, and may include a plurality of collecting ducts 50 to communicate any two directional air supply ducts 20 as needed.
The flow direction control switch 60 may be provided in a suitable form to achieve the above-described selection. For example, as shown in fig. 5, the flow direction control switch 60 includes an annular housing 61 and a baffle 62, the at least one directional air supply duct 20 includes an upstream air duct 21 located upstream of the flow direction control switch 60 and a downstream air duct 22 located downstream of the flow direction control switch 60, a first air opening 611 communicating with the downstream air duct 22 and a second air opening 612 communicating with the confluence air duct 50 are provided on the annular housing 61, the first air opening 611 and the second air opening 612 are spaced along the circumferential direction of the annular housing 61, and the baffle 62 can rotate around the center of the annular housing 61 and selectively block the first air opening 611 and the second air opening 612. Thus, the above selection can be achieved by rotating the baffle 62 so that the baffle 62 is located at a position for blocking the first tuyere 611 and the second tuyere 612, respectively.
In addition, it is also preferable that the directional air supply duct 20 of the present invention provided with the flow direction control switch 60 is closed and air is supplied only through the other directional air supply duct 20. For this, a third air opening 613 circumferentially spaced from the first air opening 611 and the second air opening 612 may be provided in the annular housing 61, the third air opening 613 is communicated with the upstream air duct 21, and the baffle plate 62 may be rotated to block the third air opening 613. When the baffle plate 62 blocks the third air opening 613, the air in the directional air supply duct 20 provided with the flow direction control switch 60 cannot continue to supply air to the downstream air duct 22.
In order to facilitate the rotation of the blocking plate 62 and to seal the flow direction control switch 60 from the leakage of the air flow, the flow direction control switch 60 includes a base plate 63 and a rotating plate 64, the base plate 63 is fixed and covered on one side of the annular housing 61, the rotating plate 64 includes a plate body portion 641 covering the other side of the annular housing 61, and the blocking plate 62 is fixed to the plate body portion 641.
Furthermore, to drive the rotation plate 64 to rotate, the flow direction control switch 60 includes a motor 65, wherein the motor 65 can drive the rotation plate 64 directly or drive the rotation plate 64 via a transmission member.
For example, in the embodiment shown in fig. 9 and 10, the plate body 641 is attached to the motor shaft of the motor 65. The motor 65 may be mounted to the directional blowing duct 20 through a motor frame 651 and protected by a motor cover 652, wherein the motor frame 651 may be provided with a clamping groove 651a for rotatably clamping the motor 65. In addition, since the rotating plate 64 can be rotated forward and backward to adjust the state at any time, the motor 65 may be a bidirectional motor. For this, a position correction stopper 651b for correcting a zero position may be provided on the motor frame 651 to stop the motor 65 when the motor 65 is in the zero position.
Alternatively, in the embodiment shown in fig. 4 to 6, the flow direction control switch 60 includes a gear 66 driven by the motor 65, the edge of the plate body 641 is provided with a tooth groove engaged with the gear 66, and the rotating plate 64 is rotatably mounted to the base plate 63. Thus, gear 66 may be driven by motor 65, which in turn rotates rotating plate 64. In order to rotatably mount the rotating plate 64 on the bottom plate 63, the rotating plate 64 may include a connecting portion 642 connected to the plate body 641, the bottom plate 63 may have a mounting hole, the connecting portion 642 may include a rotating shaft, and the rotating shaft may have an annular engaging groove 642a for rotatably engaging with the mounting hole.
The operation of the flow direction control switch 60 according to the preferred embodiment of the present invention will be described with reference to fig. 11 to 13. In the embodiment shown in fig. 1, only two directional air supply ducts 20 communicating with each other through a collecting duct 50 are shown, and a flow direction control switch 60 is provided in only one directional air supply duct 20.
When the baffle plate 62 is rotated to a position for blocking the third air opening 613, as shown in fig. 11, the cool air cannot be continuously supplied to the downstream air duct 22 along the directional air supply duct 20, and the directional air supply duct 20 provided with the flow direction control switch 60 cannot supply air to the corresponding storage compartment 40, but does not affect the supply of air to the corresponding storage compartment 40 by the other directional air supply duct 20.
When the shutter 62 is rotated to a position for blocking the second port 612, as shown in fig. 12, the cool air entering from the third port 613 does not flow through the collecting duct 50, but is entirely sent to the corresponding storage compartment 40 through the downstream duct 22. At this time, the two directional blowing ducts 20 blow air to the corresponding storage compartments 40 without interfering with each other.
When the baffle plate 62 is rotated to the position for blocking the first air opening 611, as shown in fig. 13, the cool air entering from the third air opening 613 does not flow through the downstream air duct 22, but all the cool air passing through the confluence air duct 50 and the other directional air supply duct 20 is collected and sent to the storage compartment 40 corresponding to the other directional air supply duct 20.
According to another aspect of the present invention, an air duct is provided, which includes the air supply assembly of the present invention and the cooling device 70, wherein the directional air supply duct 20 and/or the collecting duct 50 may extend through the periphery of the cooling device 70.
Since the directional supply air duct 20 and/or the collecting air duct 50 extend through the periphery of the cooling device 70, the cooling device 70 can provide a cooling effect to the directional supply air duct 20 and/or the collecting air duct 50, so that the cool air passing through the directional supply air duct 20 and/or the collecting air duct 50 is secondarily cooled by the directional supply air duct 20 and/or the collecting air duct 50. In order to enhance the secondary cooling effect, the directional air supply duct 20 and/or the collecting duct 50 are made of a metal material with good thermal conductivity.
In addition, the directional blowing air ducts 20 may be provided at both sides of the refrigerator 70 to provide support to the upper air duct of the refrigerator. To enhance this support effect, the directional supply air duct 20 may be made of a rigid structural material.
Further, as shown in fig. 8, the duct includes cover plates 80 coupled to each other and an insulation layer 90 between the cover plates 80. Wherein the refrigerating device 70 is installed on the insulating layer 90. The directional supply air duct 20 and the collecting air duct 50 may be provided in various suitable manners. For example, as shown in fig. 8, the directional supply air duct 20 and the collecting air duct 50 are formed on the insulating layer 90 or the cover plate 80 (integrally formed on the insulating layer 90 or the cover plate 80, or formed on the insulating layer 90 or the cover plate 80 to serve as passages for the directional supply air duct 20 and the collecting air duct 50); alternatively, as shown in fig. 2, the directional supply air duct 20 and the collecting air duct 50 are both pipe members and are hermetically mounted on the insulating layer 90, so that the cooling device 70 can be sealed by the directional supply air duct 20 and the collecting air duct 50.
According to another aspect of the present invention, there is provided a refrigerator including the air duct of the present invention. By using the air duct disclosed by the invention, different air supply modes can be realized through the air supply assembly.

According to the actual use situation, air can be selectively supplied to the first storage area I and/or the second storage area II through the air control device 30, so as to realize three basic air supply modes: a first mode in which air is blown only into the first storage area I, a second mode in which air is blown only into the second storage area II, and a third mode in which air is blown simultaneously into the first storage area I and the second storage area II. Therefore, when the air needs to be intensively blown to the first storage area I or the second storage area II, all cold air can be intensively blown to meet the actual requirement. For example, when the second storage area II needs to be cooled down quickly, the air can be supplied only to the directional air supply duct 20 through the air control device 30, so that all the cold air in the air cavity 10 is supplied to the second storage area II in a concentrated manner, thereby cooling down quickly.
Preferably, the second storage area II includes a plurality of storage compartments 40, and the plurality of directional blowing ducts 20 correspond to the plurality of storage compartments 40 one to one. Accordingly, the storage compartment 40 can be blown by each of the plurality of directional blowing ducts 20, or a part of the storage compartment 40 can be blown intensively by merging a part of the wind of the directional blowing ducts 20.
For example, as shown in fig. 1 and 7 (fig. 1 shows a multi-system refrigerator, a fan 300 is disposed in an air chamber 10 so as to draw cold air from outside the air chamber 10 and send the cold air to an air control device 30, fig. 7 shows a single-system refrigerator, the fan 300 is not disposed in the air chamber 10, the cold air is introduced from other parts of the refrigerator and sent to the air control device 30), the first storage area I is located above the second storage area II, the second storage area II comprises two storage compartments 40, the refrigerator may comprise two directional air supply ducts 20 for respectively sending cold air to the two storage compartments 40 and a collecting air duct 50 for communicating the two directional air supply ducts 20, and a flow direction control switch 60 is disposed at a connection position of one directional air supply duct 20 and the collecting air duct 50. Accordingly, the flow direction control switch 60 can blow air to the two corresponding storage compartments 40 through the two directional air blowing ducts 20, or blow air to one of the storage compartments 40 (for example, the left storage compartment 40 in fig. 1) by merging the two directional air blowing ducts 20.
In the present invention, the air control device 30 may be in various suitable forms as long as it can control the cool air to be selectively delivered to the first storage area I and/or the directional blowing duct 20.

The different air outlets 331 may be respectively communicated with air outlets connected to the first storage area I at different heights and an air outlet connected to the directional air supply duct 20. Through making pivot 32B drive dog B and rotate, can make different dog B shelter from different air outlets 331 at different rotational position, the air outlet 331 that is sheltered from closes, and the air outlet 331 that is not sheltered from opens (the degree that can control the shelter through the rotational position of control dog B to the degree of opening of control air outlet 331, and then the air output of control air outlet 331), thereby the cold wind that gets into from air intake 31 can be through the air supply of the air outlet 331 that is not sheltered from of difference. The first storage area I of the refrigerator and/or the directional blowing duct 20 may be blown through different blowing outlets 331.
To achieve the rotation of the rotating shaft 32b, the wind control device 30 may include a rotating bracket 34, the housing 33 is fixed to the rotating bracket 34, and the control part is rotatably mounted to the rotating bracket 34.
In the present invention, the rotating shaft 32b may be driven by any suitable means, for example, the wind control device 30 may include a driving motor 35 for driving the control portion to rotate, and the outside of the driving motor 35 may be protected by a protective cover 351. Preferably, the driving motor 35 is a bi-directional motor to more precisely drive the rotation shaft 32b to a desired operation mode within a range of 360 °. In order to accurately determine the start or end position of the 360 ° rotation range, the driving shaft 32b and the rotating bracket 34 are preferably provided with stop structures that cooperate with each other.
