Hereinafter, a cross flow rotor 100 according to the present utility model will be described with reference to the accompanying drawings.

As shown in fig. 1 to 4, a cross-flow wind wheel 100 according to an embodiment of the present utility model includes: the installation plate 1 and the wind-guiding blades 2, the installation plate 1 is at least two, the installation plate 1 is arranged along the axial direction of the cross-flow wind wheel 100 at intervals, the installation plate 1 is the main body of the cross-flow wind wheel 100, the wind-guiding blades 2 are connected between two adjacent installation plates 1, and the installation plates 1 play roles in supporting and installing. When the cross-flow wind wheel 100 rotates, all the mounting plates 1 synchronously rotate, air flows enter the cross-flow wind wheel 100 from the opening position of the cross-flow wind wheel 100, and the air flows are sent out along the tangential direction of the rotation direction of the cross-flow wind wheel 100 under the action of a plurality of air guide blades 2.

The number of the installation discs 1 can be reasonably selected according to the length required by the cross-flow fan, the number of the installation discs 1 is also related to the length of the air guide blades 2, and therefore the number of the installation discs 1 can be selected according to actual needs, and the number of the installation discs 1 is not particularly limited.

Alternatively, the mounting plate 1 may be a disk member, and the mounting plate 1 may also be a disk member of another shape, without being particularly limited thereto. It will be appreciated that the mounting plate 1 needs to be rotated for wind guiding and therefore the mounting plate 1 is generally a centrosymmetric member to promote rotational stability of the mounting plate 1. The mounting plates 1 are arranged at intervals along the axial direction of the cross-flow wind wheel 100, the mounting plates 1 are parallel to each other, and the mounting plates 1 overlap each other in the axial direction.

As shown in fig. 1 and 2, the wind guiding blade 2 is a main functional component of the through-flow wind wheel 100, a plurality of wind guiding blades 2 are arranged at intervals in the circumferential direction of the through-flow wind wheel 100, the wind guiding blade 2 comprises a connecting part 22 and a wind guiding part 21, the wind guiding part 21 is a main functional component of the wind guiding blade 2, the wind guiding part 21 guides the air flow so as to make the air flow sent out from the through-flow wind wheel 100 in a directional manner, and the wind guiding part 21 is connected to the mounting plate 1 through the connecting part 22. The wind guiding blades 2 are connected between two adjacent installation discs 1 through the connecting portions 22, so the connection mode of the connecting portions 22 and the installation discs 1 is hereinafter described as the connection mode of the connecting portions 22 and the two installation discs 1, and the description is omitted.

At least one air guide blade 2 of the plurality of air guide blades 2 is a movable air guide blade 20, and a connecting part 22 of the movable air guide blade 20 is rotatably connected with the mounting plate 1, or the connecting part 22 of the movable air guide blade 20 is slidably connected with the mounting plate 1. The connecting part 22 of the movable air guide blade 20 is provided with a first position and a second position which can be switched on the mounting plate 1, the connecting part 22 of the movable air guide blade 20 can move between the first position and the second position, and the movable air guide blade 20 can move relative to the mounting plate 1 under the driving of the connecting part 22.

When the cross-flow wind wheel 100 rotates along the first direction F1, the connection portion 22 of the movable wind guiding blade 20 moves to the first position under the action of the centrifugal force, so as to guide wind in the forward direction. When the cross-flow wind wheel 100 rotates, the installation plates 1 synchronously rotate, so as shown in fig. 3, an example of one installation plate 1 in the cross-flow wind wheel 100 and the movable air guide blades 20 on the installation plate 1 will be described, so that all the movable air guide blades 20 in the cross-flow wind wheel 100 of the present utility model can be described, and understanding of the cross-flow wind wheel 100 of the present utility model is facilitated. When the cross-flow wind wheel 100 rotates along the first direction F1, that is, when the mounting plate 1 rotates along the first direction F1, the movable air guide blade 20 on the mounting plate 1 moves to the first position under the action of centrifugal force, the movable air guide blade 20 moves relative to the mounting plate 1, and the movable air guide blade 20 is forward air guide to the air flow at the moment, so that the cross-flow wind wheel 100 can supply air in one direction. Similarly, as shown in fig. 4, when the cross-flow wind wheel 100 rotates along the second direction F2 opposite to the first direction F1, that is, when the mounting plate 1 rotates along the second direction F2, the movable air guide blade 20 on the mounting plate 1 moves to the second position under the action of centrifugal force, the movable air guide blade 20 moves relative to the mounting plate 1, and the movable air guide blade 20 is used for guiding air reversely to the air flow at this time, so that the cross-flow wind wheel 100 can supply air in the other direction.

It should be noted that, when the forward direction wind guiding of the movable wind guiding blade 20 and the reverse direction wind guiding of the movable wind guiding blade 20 only indicate that the connecting portion 22 of the movable wind guiding blade 20 is located at the first position and the second position, the movable wind guiding blade 20 will guide the air flow in different directions, rather than restricting the connecting portion 22 of the movable wind guiding blade 20 to be located at the first position and the second position, the movable wind guiding blade 20 will guide the air flow in two completely opposite directions.

Optionally, when the cross-flow wind wheel 100 changes from the first direction F1 to rotate along the second direction F2, the connection portion 22 of the movable wind guiding blade 20 moves from the first position to the second position on the mounting plate 1, the movable wind guiding blade 20 guides the airflow, and the outflow angle of the airflow changes. For example, when the cross-flow wind wheel 100 rotates along the first direction F1 and the connection portion 22 of the movable wind guide blade 20 moves to the first position, the first air channel of the cross-flow wind wheel 100 is air-fed, and the second air channel of the cross-flow wind wheel 100 is air-fed; when the cross-flow wind wheel 100 rotates along the second direction F2 and the connecting portion 22 of the movable wind guiding blade 20 moves to the second position, the air in the first air duct of the cross-flow wind wheel 100 enters, the air in the third air duct of the cross-flow wind wheel 100 exits, and the cross-flow wind wheel 100 supplies air in different directions. According to the cross flow wind wheel 100 provided by the embodiment of the utility model, air can be supplied in different directions, the air supply capacity is improved, and the air flow coverage area is increased.

Still alternatively, the movable wind guiding blade 20 has a larger movement amplitude relative to the mounting plate 1, and when the through-flow wind wheel 100 rotates in the opposite direction towards the second direction F2 and the connecting portion 22 of the movable wind guiding blade 20 moves from the first position to the second position on the mounting plate 1, the guiding of the wind guiding blade 2 to the airflow does not simply change the airflow outflow angle, but makes the airflow direction completely reverse. For example, when the cross-flow wind wheel 100 rotates along the first direction F1 and the connection portion 22 of the movable wind guide blade 20 moves to the first position, the first air channel of the cross-flow wind wheel 100 is air-fed, and the second air channel of the cross-flow wind wheel 100 is air-fed; when the cross-flow wind wheel 100 rotates along the second direction F2 and the connecting portion 22 of the movable wind guiding blade 20 moves to the second position, the second air duct of the cross-flow wind wheel 100 is air-fed, the first air duct of the cross-flow wind wheel 100 is air-discharged, and the cross-flow wind wheel 100 supplies air reversely. The cross flow wind wheel 100 of the embodiment of the utility model can supply air in two diametrically opposite directions, thereby improving the air supply capacity and the functionality of the cross flow wind wheel 100.

It should also be noted that when part of the air guide vanes 2 are movable air guide vanes 20 and the other part of the air guide vanes 2 are immovably connected with the mounting plate 1. The movable air guide blade 20 has a guiding effect on the air flow, and other non-movable air guide blades 2 also have a guiding effect on the air flow, so that the cross-flow fan can realize multiple air supply modes.

Optionally, when part of the air guide blades 2 are movable air guide blades 20, the other part of the air guide blades 2 are immovably connected with the mounting plate 1, and the immovable air guide blades 2 are suitable for forward air guide, the cross-flow wind wheel 100 rotates along the first direction F1, and when the connecting parts 22 of the movable air guide blades 20 move to the first position, all the air guide blades 2 forward air guide, and the air output of the cross-flow wind wheel 100 is larger; and when the cross-flow wind wheel 100 rotates along the second direction F2 and the connecting part 22 of the movable wind guiding blade 20 moves to the second position, only the movable wind guiding blade 20 is used for guiding wind reversely, and the air output of the cross-flow wind wheel 100 is smaller. Still alternatively, when part of the air guide blades 2 are movable air guide blades 20, and the other part of the air guide blades 2 are immovably connected with the mounting plate 1, and the immovable air guide blades 2 are suitable for reverse air guide, the through-flow wind wheel 100 rotates along the first direction F1, only the movable air guide blades 20 forward guide air, the air output of the through-flow wind wheel 100 is smaller, the through-flow wind wheel 100 rotates along the second direction F2, and therefore the air guide blades 2 all guide air reversely, and the air output of the through-flow wind wheel 100 is larger. The cross flow wind wheel 100 can supply air in different directions, improves the air supply capacity, has different air output in different directions and meets different air supply requirements.

In the process of rotation of the cross-flow wind wheel 100, the movable air guide blade 20 can be driven to move relative to the mounting plate 1, under the combined action of centrifugal force generated in rotation of the cross-flow wind wheel 100 and acting force of air on the movable air guide blade 20 when the cross-flow wind wheel 100 rotates, the connecting part 22 of the movable air guide blade 20 can move between the first position and the second position, and a driving piece for driving the connecting part 22 of the movable air guide blade 20 to move is not required to be additionally arranged, so that the structure is simplified, the structural complexity of the cross-flow wind wheel 100 is reduced, and the manufacturing cost of the cross-flow wind wheel 100 is saved.

The cross flow wind wheel 100 of the present utility model may be applied to air moving equipment, which illustratively includes, but is not limited to, various types of air conditioners, such as air conditioning hangers, cabinet air conditioners, movers, window winders, fresh air blowers, ducted air blowers, and the like.

The air conditioner applying the cross flow wind wheel 100 of the embodiment of the utility model realizes bidirectional air supply, and each direction is independently supplied with air, thereby increasing the air supply range of the air conditioner and improving the air flow coverage area of the air conditioner. And the air conditioner can realize bidirectional air supply by only arranging one cross flow wind wheel 100, thereby reducing the structural complexity and the manufacturing cost of the air conditioner.

Still alternatively, the air conditioner applying the cross flow wind wheel 100 of the embodiment of the present utility model has an air inlet and an air outlet, when the cross flow wind wheel 100 rotates along the first direction F1, the connection portion 22 of the movable wind guiding blade 20 moves to the first position, the cross flow wind wheel 100 supplies air, and the air conditioner is in a normal air supply mode of air inlet and air outlet; when the cross-flow wind wheel 100 rotates along the second direction F2, the connecting portion 22 of the movable wind guiding blade 20 moves to the second position, the cross-flow wind wheel 100 supplies air, and the air conditioner is in a reverse air supply mode of air inlet of the air outlet and air outlet of the air inlet. The directions of the air inlet and the air outlet are different, so that the air conditioner applying the cross flow wind wheel 100 provided by the embodiment of the utility model realizes bidirectional air supply, the air flow coverage area of the air conditioner is increased, and the air conditioner can realize bidirectional air supply by only arranging one cross flow wind wheel 100, thereby reducing the structural complexity and the manufacturing cost of the air conditioner. When the air inlet is arranged at the top of the air conditioner and the air outlet is arranged at the bottom of the air conditioner, the air conditioner applying the cross flow wind wheel 100 of the embodiment of the utility model can also output refrigerating air flow from the top and heating air flow from the bottom, thereby improving the comfort of refrigerating and heating of the air conditioner. In addition, the air flow direction between the air inlet and the air outlet is switched, so that the reverse blowing dust removal can be realized, and the cleanliness of the air conditioner is improved.

According to the cross-flow wind wheel 100 of the embodiment of the utility model, by arranging the movable wind guide blade 20, the connection part 22 of the movable wind guide blade 20 can be switched between the first position and the second position, so that the movable wind guide blade 20 guides wind in different directions. The cross flow wind wheel 100 can supply air in different directions, and the cross flow wind wheel 100 has strong air supply capability and wide air flow coverage area. In addition, in the rotating process of the cross-flow wind wheel 100, the movable wind guide blade 20 can be driven to move relative to the mounting plate 1 without additionally arranging a driving piece, so that the structure is simplified, the structural complexity of the cross-flow wind wheel 100 is reduced, and the manufacturing cost of the cross-flow wind wheel 100 is saved. The air conditioner applying the cross flow wind wheel 100 of the embodiment of the utility model can realize two-direction air supply only by arranging one cross flow wind wheel 100, thereby being capable of increasing the air supply range and reducing the structural complexity and the manufacturing cost of the air conditioner.
