However, after the crossflow fan structure in the prior art is determined, it can only supply air in a directional manner according to the set structure.

To this end, the present invention proposes a crossflow fan wheel, which can send air in two directions and has a strong air supply capacity. An air conditioner using the crossflow fan wheel only needs to be provided with one crossflow fan wheel to achieve air supply in two directions, thereby increasing the air supply range and reducing the structural complexity and manufacturing cost.

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0041] Hereinafter, the crossflow impeller 100 according to the present invention will be described with reference to the accompanying drawings.

[0042] like Figure 1-Figure 4 As shown, the crossflow fan 100 according to the embodiment of the present invention comprises: a mounting disc 1 and a guide vane 2. There are at least two mounting discs 1, which are arranged at intervals along the axial direction of the crossflow fan 100. The mounting disc 1 is the main body of the crossflow fan 100. The guide vane 2 is connected between two adjacent mounting discs 1, and the mounting disc 1 plays a supporting and mounting role. When the crossflow fan 100 rotates, all mounting discs 1 rotate synchronously, and the airflow enters the inside of the crossflow fan 100 from the opening of the crossflow fan 100. Under the action of the multiple guide vanes 2, the airflow is sent out along the tangent direction of the rotation direction of the crossflow fan 100.

[0043] The number of mounting plates 1 can be reasonably selected according to the required length of the cross-flow fan. The number of mounting plates 1 is also related to the length of the guide blades 2. Therefore, the number of mounting plates 1 can be selected according to actual needs and is not specifically limited here.

[0044] Optionally, the mounting disk 1 may be a disc, or a disc-shaped member of other shapes, which is not specifically limited here. However, it is understandable that the mounting disk 1 needs to rotate to guide the wind, so the mounting disk 1 is generally a centrally symmetrical member to improve the rotational stability of the mounting disk 1. The mounting disks 1 are arranged at intervals along the axial direction of the crossflow impeller 100, the mounting disks 1 are parallel to each other, and the mounting disks 1 overlap each other in the axial direction.

[0045] like Figure 1 and Figure 2 As shown, the guide vane 2 is the main functional part of the crossflow wind wheel 100. A plurality of guide vanes 2 are arranged at intervals in the circumferential direction of the crossflow wind wheel 100. The guide vane 2 includes a connecting portion 22 and a guide portion 21. The guide portion 21 is the main functional part of the guide vane 2. The guide portion 21 guides the airflow so that the airflow is sent out from the crossflow wind wheel 100 in a directional manner. The guide portion 21 is connected to the mounting plate 1 through the connecting portion 22. The guide vane 2 is connected between two adjacent mounting plates 1 through the connecting portion 22. Therefore, the description of the connection mode of the connecting portion 22 and the mounting plate 1 below is the connection mode of the connecting portion 22 and the two mounting plates 1, which will not be repeated in the description process.

[0046] At least one of the plurality of air guide blades 2 is a movable air guide blade 20, and a connection portion 22 of the movable air guide blade 20 is rotatably connected to the mounting plate 1, or the connection portion 22 of the movable air guide blade 20 is slidably connected to the mounting plate 1. The connection portion 22 of the movable air guide blade 20 has a switchable first position and a second position on the mounting plate 1, and the connection portion 22 of the movable air guide blade 20 can move between the first position and the second position. Driven by the connection portion 22, the movable air guide blade 20 can move relative to the mounting plate 1.

[0047] When the crossflow impeller 100 rotates in the first direction F1, the connecting portion 22 of the movable air guide vane 20 moves to the first position under the action of centrifugal force to guide the air in the positive direction. When the crossflow impeller 100 rotates, the mounting plate 1 rotates synchronously. Figure 3 As shown, by taking a mounting disk 1 in a crossflow wind wheel 100 and the movable guide vanes 20 on the mounting disk 1 as an example, all the movable guide vanes 20 in the crossflow wind wheel 100 of the present invention can be described to facilitate the understanding of the crossflow wind wheel 100 of the present invention. When the crossflow wind wheel 100 rotates along the first direction F1, that is, when the mounting disk 1 rotates along the first direction F1, the movable guide vanes 20 on the mounting disk 1 are subjected to the action of centrifugal force, and the connecting parts 22 of the movable guide vanes 20 move to the first position, and the movable guide vanes 20 move relative to the mounting disk 1. At this time, the movable guide vanes 20 guide the air flow positively, so that the crossflow wind wheel 100 can deliver air in one direction. Similarly, Figure 4 As shown, when the crossflow fan wheel 100 rotates in a second direction F2 opposite to the first direction F1, that is, when the mounting plate 1 rotates in the second direction F2, the movable guide vanes 20 on the mounting plate 1 are moved to the second position by the centrifugal force, and the connecting portion 22 of the movable guide vanes 20 moves to the second position, and the movable guide vanes 20 move relative to the mounting plate 1. At this time, the movable guide vanes 20 guide the air in the reverse direction of the airflow, so that the crossflow fan wheel 100 can supply air in another direction.

[0048] It is worth mentioning that the forward air guiding of the movable air guide blade 20 and the reverse air guiding of the movable air guide blade 20 only express that when the connecting portion 22 of the movable air guide blade 20 is located in the first position and the second position, the movable air guide blade 20 will guide the airflow in different directions, rather than limiting that when the connecting portion 22 of the movable air guide blade 20 is located in the first position and the second position, the movable air guide blade 20 will guide the airflow in two completely opposite directions.

[0049] Optionally, when the crossflow fan wheel 100 changes from the first direction F1 to the second direction F2, the connection portion 22 of the movable air guide blade 20 moves from the first position to the second position on the mounting plate 1, and the movable air guide blade 20 guides the airflow, and the outflow angle of the airflow changes. For example, when the crossflow fan wheel 100 rotates along the first direction F1, the connection portion 22 of the movable air guide blade 20 moves to the first position, the first air duct of the crossflow fan wheel 100 enters the air, and the second air duct of the crossflow fan wheel 100 exits the air; when the crossflow fan wheel 100 rotates along the second direction F2, the connection portion 22 of the movable air guide blade 20 moves to the second position, at this time, the first air duct of the crossflow fan wheel 100 enters the air, and the third air duct of the crossflow fan wheel 100 exits the air, and the crossflow fan wheel 100 sends air in different directions. The crossflow fan wheel 100 of the embodiment of the present invention can send air in different directions, improve the air supply capacity, and increase the airflow coverage area.

[0050] Optionally, the movable air guide blade 20 has a larger movement range relative to the mounting plate 1. When the crossflow fan wheel 100 rotates in the opposite direction toward the second direction F2 and the connecting portion 22 of the movable air guide blade 20 moves from the first position to the second position on the mounting plate 1, the air guide blade 2 guides the airflow not by simply changing the outflow angle of the airflow, but by completely reversing the airflow direction. For example, when the crossflow fan wheel 100 rotates along the first direction F1 and the connecting portion 22 of the movable air guide blade 20 moves to the first position, the first air duct of the crossflow fan wheel 100 takes in air and the second air duct of the crossflow fan wheel 100 discharges air; when the crossflow fan wheel 100 rotates along the second direction F2 and the connecting portion 22 of the movable air guide blade 20 moves to the second position, the second air duct of the crossflow fan wheel 100 takes in air and the first air duct of the crossflow fan wheel 100 discharges air, and the crossflow fan wheel 100 supplies air in the opposite direction. The crossflow impeller 100 according to the embodiment of the present invention can deliver air in two completely opposite directions, thereby improving the air delivery capacity and the functionality of the crossflow impeller 100 .

[0051] It is also worth noting that when some of the air guide blades 2 are movable air guide blades 20 and other parts of the air guide blades 2 are immovably connected to the mounting plate 1, the movable air guide blades 20 have a guiding effect on the airflow, and the other immovable air guide blades 2 also have a guiding effect on the airflow, so that the crossflow fan of the present invention can achieve multiple air supply modes.

[0052] Optionally, when some of the guide blades 2 are movable guide blades 20, and other part of the guide blades 2 are immovably connected to the mounting plate 1, and the immovable guide blades 2 are suitable for forward wind guidance, the crossflow wind wheel 100 rotates along the first direction F1, and when the connecting portion 22 of the movable guide blades 20 moves to the first position, all the guide blades 2 guide the wind forward, and the air output of the crossflow wind wheel 100 is large; and when the crossflow wind wheel 100 rotates along the second direction F2, and when the connecting portion 22 of the movable guide blades 20 moves to the second position, only the movable guide blades 20 guide the wind in the reverse direction, and the air output of the crossflow wind wheel 100 is small. Alternatively, when some of the guide blades 2 are movable guide blades 20, and other parts of the guide blades 2 are immovably connected to the mounting plate 1, and the immovable guide blades 2 are suitable for reverse wind guidance, the crossflow wind wheel 100 rotates along the first direction F1, and only the movable guide blades 20 are forwardly guiding the wind, and the air output of the crossflow wind wheel 100 is small. The crossflow wind wheel 100 rotates along the second direction F2, so the guide blades 2 are all reversely guiding the wind, and the air output of the crossflow wind wheel 100 is large. The crossflow wind wheel 100 of the present invention can send air in different directions to improve the air supply capacity, and the air output in different directions is different to meet different air supply requirements.

[0053] During the rotation process, the crossflow wind wheel 100 of the present invention can drive the movable guide vanes 20 to move relative to the mounting plate 1. Under the combined effect of the centrifugal force generated during the rotation of the crossflow wind wheel 100 and the force of the air on the movable guide vanes 20 when the crossflow wind wheel 100 rotates, the connecting portion 22 of the movable guide vanes 20 can move between the first position and the second position without the need to additionally provide a driving component for driving the connecting portion 22 of the movable guide vanes 20 to move, thereby streamlining the structure, reducing the structural complexity of the crossflow wind wheel 100, and saving the manufacturing cost of the crossflow wind wheel 100.

[0054] The crossflow impeller 100 of the present invention can be applied to air supply equipment. Exemplarily, the air supply equipment includes but is not limited to various types of air conditioners, such as wall-mounted air conditioners, cabinet air conditioners, mobile air conditioners, window air conditioners, fresh air fans, duct air conditioners, etc.

[0055] The following description will be made by taking the application of the crossflow impeller 100 to an air conditioner as an example to facilitate the understanding of the crossflow impeller 100 of the present invention.

[0056] Optionally, the air conditioner using the crossflow fan wheel 100 of the embodiment of the present invention has a first air outlet and a second air outlet. When the crossflow fan wheel 100 rotates along the first direction F1, the connection portion 22 of the movable air guide blade 20 moves to the first position, the crossflow fan wheel 100 supplies air, the air conditioner discharges air through the first air outlet, and no air flows out of the second air outlet; when the crossflow fan wheel 100 rotates along the second direction F2, the connection portion 22 of the movable air guide blade 20 moves to the second position, the crossflow fan wheel 100 supplies air, the air conditioner discharges air through the second air outlet, and no air flows out of the first air outlet. The air conditioner using the crossflow fan wheel 100 of the embodiment of the present invention realizes two-way air supply, and each direction independently supplies air, thereby increasing the air supply range of the air conditioner and improving the airflow coverage area of ​​the air conditioner. In addition, the air conditioner only needs to be provided with one crossflow fan wheel 100 to realize two-way air supply, which can reduce the structural complexity and manufacturing cost of the air conditioner.

[0057] Optionally, the air conditioner using the crossflow fan wheel 100 of the embodiment of the present invention has an air inlet and an air outlet. When the crossflow fan wheel 100 rotates along the first direction F1, the connection part 22 of the movable air guide blade 20 moves to the first position, the crossflow fan wheel 100 supplies air, and the air conditioner is in a normal air supply mode with air entering through the air inlet and air leaving through the air outlet; when the crossflow fan wheel 100 rotates along the second direction F2, the connection part 22 of the movable air guide blade 20 moves to the second position, the crossflow fan wheel 100 supplies air, and the air conditioner is in a reverse air supply mode with air entering through the air outlet and air leaving through the air inlet. The directions of the air inlet and the air outlet are different, so the air conditioner using the crossflow fan wheel 100 of the embodiment of the present invention realizes two-way air supply, improves the airflow coverage area of ​​the air conditioner, and the air conditioner only needs to be provided with one crossflow fan wheel 100 to realize two-way air supply, which can reduce the structural complexity and manufacturing cost of the air conditioner. When the air inlet is set at the top of the air conditioner and the air outlet is set at the bottom of the air conditioner, the air conditioner using the crossflow impeller 100 of the embodiment of the present invention can also output cooling airflow from the top and heating airflow from the bottom, thereby improving the comfort of cooling and heating of the air conditioner. In addition, the switching of the airflow direction between the air inlet and the air outlet can also realize reverse blowing and dust removal, thereby improving the cleanliness of the air conditioner.

[0058] According to the crossflow fan wheel 100 of the embodiment of the present invention, by setting the movable air guide blade 20, the connection part 22 of the movable air guide blade 20 can be switched between the first position and the second position, so that the movable air guide blade 20 can guide the air in different directions. The crossflow fan wheel 100 can supply air in different directions, and the crossflow fan wheel 100 has a strong air supply capacity and a wide airflow coverage area. In addition, during the rotation of the crossflow fan wheel 100, the movable air guide blade 20 can be driven to move relative to the mounting plate 1 without the need to additionally set up a driving part, thereby simplifying the structure, reducing the structural complexity of the crossflow fan wheel 100, and saving the manufacturing cost of the crossflow fan wheel 100. The air conditioner using the crossflow fan wheel 100 of the embodiment of the present invention only needs to set up one crossflow fan wheel 100 to achieve air supply in two directions, thereby increasing the air supply range and reducing the structural complexity and manufacturing cost of the air conditioner.

[0059] In some embodiments of the present invention, all the guide blades 2 are movable guide blades 20. When the crossflow wind wheel 100 rotates along the first direction F1, the connection parts 22 of all the guide blades 2 are moved to the first position under the action of centrifugal force, and all the guide blades 2 are forwardly guiding the wind. When the crossflow wind wheel 100 rotates along the second direction F2, the connection parts 22 of all the guide blades 2 are moved to the second position under the action of centrifugal force, and all the guide blades 2 are reversely guiding the wind, thereby increasing the air output of the crossflow wind wheel 100.

[0060] In other embodiments of the present invention, part of the air guide is a movable air guide blade 20, and the movable air guide blade 20 and the immovable air guide blade 2 are arranged at a preset ratio. For example, the movable air guide blade 20 and the immovable air guide blade 2 are alternately arranged along the circumference of the crossflow impeller 100 at a ratio of two to one.

[0061] In some further embodiments of the present invention, part of the air guides are movable air guide blades 20, there are at least three mounting plates 1, the air guide blades 2 between at least two adjacent mounting plates 1 are movable air guide blades 20, and the air guide blades 2 between at least two adjacent mounting plates 1 are immovable air guide blades 2.

[0062] In some embodiments of the present invention, Figure 2 As shown, the connection portion 22 of the movable air guide blade 20 includes a first connection portion 221 and a second connection portion 222, and the air guide portion 21 is respectively connected to the first connection portion 221 and the second connection portion 222. The movable air guide blade 20 is connected to the mounting plate 1 through the first connection portion 221 and the second connection portion 222, which can improve the installation stability of the movable air guide blade 20, and through the two connection portions 22, the movement of the movable air guide blade 20 relative to the mounting plate 1 is more stable.

[0063] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the length direction F3 of the movable air guide blade 20 is parallel to the axial direction of the mounting plate 1, and the two ends of the length direction F3 of the movable air guide blade 20 are respectively connected to two adjacent mounting plates 1. The two ends of the width direction F4 of the movable air guide blade 20 are provided with a first connection portion 221 and a second connection portion 222, and the air guide portion 21 is between the first connection portion 221 and the second connection portion 222, and the width direction F4 of the movable air guide blade 20 is close to the radial direction of the mounting plate 1.

[0064] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the distance between the first connection part 221 and the axis of the crossflow wind wheel 100 is greater than the distance between the second connection part 222 and the axis of the crossflow wind wheel 100. It can be understood that the mounting plate 1 is the main body of the crossflow wind wheel 100. When the crossflow wind wheel 100 rotates, it rotates with the axis of the crossflow wind wheel 100 as the rotation center. When the mounting plate 1 rotates synchronously, it also rotates with the axis of the mounting plate 1 as the rotation center. The axis of the mounting plate 1 is colinear with the axis of the crossflow wind wheel 100, and the center of the mounting plate 1 is located on the axis of the mounting plate 1. Therefore, Figure 3 , Figure 4 and Figure 8As shown, the distance between the first connection part 221 and the center of the mounting disk 1 is greater than the distance between the second connection part 222 and the center of the mounting disk 1, that is, the first connection part 221 is located on the side away from the center of the mounting disk 1 relative to the second connection part 222, and the first connection part 221 is located radially outside the mounting disk 1 of the second connection part 222.

[0065] In some embodiments of the present invention, at least one of the first connecting portion 221 and the second connecting portion 222 is slidably disposed on the mounting plate 1 .

[0066] Optionally, the first connection portion 221 is slidably disposed on the mounting plate 1, and the second connection portion 222 is immovably disposed on the mounting plate 1. The first connection portion 221 has a first position and a second position on the mounting plate 1. When the crossflow impeller 100 rotates along the first direction F1, the first connection portion 221 slides to the first position under the action of centrifugal force; when the crossflow impeller 100 rotates along the second direction F2, the first connection portion 221 slides to the second position under the action of centrifugal force, and the movable guide vane 20 can guide wind in different directions.

[0067] Alternatively, if Figure 3 and Figure 4 As shown, the first connection part 221 is immovably disposed on the mounting plate 1, and the second connection part 222 is slidably disposed on the mounting plate 1. The second connection part 222 has a first position and a second position on the mounting plate 1. When the crossflow impeller 100 rotates along the first direction F1, the second connection part 222 slides to the first position under the action of centrifugal force; when the crossflow impeller 100 rotates along the second direction F2, the second connection part 222 slides to the second position under the action of centrifugal force, and the movable guide vane 20 can guide the wind in different directions.

[0068] Alternatively, the first connection portion 221 and the second connection portion 222 may be slidably disposed on the mounting plate 1.

[0072] Optionally, the slide groove 11 is a straight groove; further optionally, the slide groove 11 is a curved groove. Figure 5 As shown, the slide groove 11 is an arc groove, and the first connecting part 221 and / or the second connecting part 222 slide along the arc track to improve the smoothness of movement, so that the connecting part 22 of the movable air guide blade 20 can smoothly switch between the first position and the second position, thereby improving the working stability of the movable air guide blade 20.

[0073] By setting the slide groove 11, the sliding of the first connection part 221 and / or the second connection part 222 can be guided and limited. The first connection part 221 and / or the second connection part 222 can slide along the slide groove 11, thereby improving the movement stability of the first connection part 221 and / or the second connection part 222, improving the movement deviation of the first connection part 221 and / or the second connection part 222 under the action of centrifugal force, and improving the working stability of the movable guide blade 20.

[0074] The slide grooves 11 are arranged correspondingly to the movable air guide vanes 20. The movable air guide vanes 20 are arranged at intervals along the circumference of the crossflow wind wheel 100, and the slide grooves 11 are also arranged at intervals along the circumference of the crossflow wind wheel 100. The number of the slide grooves 11 and the slidable first connecting parts 221 and / or the second connecting parts 222 corresponds to each other, so that the plurality of movable air guide vanes 20 can cooperate with the slide grooves 11 to move stably, thereby improving the working stability of the movable air guide vanes 20.

[0075] Alternatively, if Figure 3 and Figure 4 As shown, the first connection part 221 is immovably arranged on the mounting plate 1, and the second connection part 222 is slidably arranged on the mounting plate 1.

[0076] Alternatively, the first connection portion 221 is slidably disposed on the mounting disk 1, and the second connection portion 222 is immovably disposed on the mounting disk 1. A slide groove 11 matching the first connection portion 221 is disposed on the mounting disk 1. The slide grooves 11 are also multiple and are disposed one-to-one with the first connection portions 221. The slide grooves 11 are arranged at intervals along the circumference of the mounting disk 1. The first connection portion 221 has a first position located at the end of the slide groove 11 in the first direction F1 and a second position located at the end of the slide groove 11 in the second direction F2. When the crossflow impeller 100 rotates, the first connection portion 221 can be driven to slide between the first position and the second position under the action of centrifugal force and airflow.

When the first connection portion 221 slides to the end of the first direction F1 of the corresponding slide slot 11, and the second connection portion 222 slides to the end of the second direction F2 of the corresponding slide slot 11, the connection portion 22 of the movable air guide vane 20 is located at the first position; when the first connection portion 221 slides to the end of the second direction F2 of the corresponding slide slot 11, and the second connection portion 222 slides to the end of the first direction F1 of the corresponding slide slot 11, the connection portion 22 of the movable air guide vane 20 is located at the second position. When the crossflow impeller 100 rotates, the connection portion 22 of the movable air guide vane 20 can be driven to slide between the first position and the second position under the action of centrifugal force and airflow.

[0078] In some embodiments of the present invention, Figure 7 As shown, limiting ribs 13 are respectively provided on the inner wall of the slide groove 11 near both ends to limit the first connection part 221 and / or the second connection part 222 at the first position or the second position, thereby improving the first connection part 221 and / or the second connection part 222 from erroneously coming out of the first position or the second position, and improving the working stability of the movable air guide blade 20.

A slide groove 11 matching with the second connection part 222 is arranged on the mounting plate 1, and the second connection part 222 has a first position located at the end of the slide groove 11 in the second direction F2 and a second position located at the end of the slide groove 11 in the first direction F1. When the crossflow impeller 100 rotates along the second direction F2, under the action of centrifugal force and airflow, the second connection part 222 slides toward the first direction F1, and the second connection part 222 first escapes from the space between the limiting rib 13 near one end of the second direction F2 and the end of the slide groove 11, and then snaps into the space between the limiting rib 13 near one end of the first direction F1 and the end of the slide groove 11, and the limiting rib 13 limits the second connection part 222 at the second position, thereby improving the working stability of the movable air guide blade 20.

[0080] In some embodiments of the present invention, the mounting plate 1 is further provided with a mounting hole 12, one of the first connection portion 221 and the second connection portion 222 is matched in the mounting hole 12, one of the first connection portion 221 and the second connection portion 222 that matches the mounting hole 12 is rotatably connected to the mounting plate 1, the other of the first connection portion 221 and the second connection portion 222 is matched in the slide slot 11, one of the first connection portion 221 and the second connection portion 222 that matches the slide slot 11 is slidably connected to the mounting plate 1. There are also multiple mounting holes 12 and they are arranged one-to-one with the slide slots 11, and the mounting holes 12 are also arranged at intervals along the circumference of the crossflow impeller 100.

[0081] Alternatively, if Figure 3-Figure 5 As shown, the first connection part 221 is matched in the mounting hole 12, the first connection part 221 is rotatably arranged on the mounting plate 1, the second connection part 222 is matched in the slide groove 11, the second connection part 222 is slidably arranged on the mounting plate 1, and the movable air guide vane 20 can drive the second connection part 222 to slide with the first connection part 221 as the rotation center. The first connection part 221 is located on the side of the second connection part 222 away from the center of the mounting plate 1. When the crossflow impeller 100 rotates along the first direction F1, under the action of centrifugal force, the first connection part 221 rotates along the second direction F2, and the second connection part 222 is driven to slide to the first position; when the crossflow impeller 100 rotates along the second direction F2, under the action of centrifugal force, the first connection part 221 rotates along the first direction F1, and the second connection part 222 is driven to slide to the second position, and the movable air guide vane 20 can guide the wind in different directions.

[0082] Alternatively, the first connection part 221 is fitted in the slide slot 11, the first connection part 221 is swingably arranged on the mounting plate 1, the second connection part 222 is fitted in the mounting hole 12, the second connection part 222 is rotatably arranged on the mounting plate 1, and the movable air guide vane 20 can drive the first connection part 221 to move with the second connection part 222 as the rotation center. The first connection part 221 is located on the side of the second connection part 222 away from the center of the mounting plate 1. When the crossflow impeller 100 rotates along the first direction F1, under the action of centrifugal force, the second connection part 222 rotates along the first direction F1, and the first connection part 221 is driven to slide to the first position; when the crossflow impeller 100 rotates along the second direction F2, under the action of centrifugal force, the second connection part 222 rotates along the second direction F2, and the first connection part 221 is driven to slide to the second position, and the movable air guide vane 20 can guide the wind in different directions.

[0083] In some embodiments of the present invention, the slide groove 11 is an arc-shaped groove that bulges in a direction away from the mounting hole 12. One of the first connection portion 221 and the second connection portion 222 fits in the mounting hole 12, and the other of the first connection portion 221 and the second connection portion 222 fits in the slide groove 11. The one of the first connection portion 221 and the second connection portion 222 that fits in with the slide groove 11 rotates with the axis of the mounting hole 12 as the rotation center, so the slide groove 11 is an arc-shaped groove, and the one of the first connection portion 221 and the second connection portion 222 that fits in with the slide groove 11 has better movement smoothness when sliding along the arc track, so that the connection portion 22 of the movable air guide blade 20 can smoothly switch between the first position and the second position, thereby improving the working stability of the movable air guide blade 20.

[0084] Alternatively, if Figure 3-Figure 5 As shown, the first connection portion 221 is fitted in the mounting hole 12, and the second connection portion 222 is fitted in the slide groove 11, and the first connection portion 221 is located on the side of the second connection portion 222 away from the center of the mounting disk 1. Correspondingly, the mounting hole 12 is located on the side of the slide groove 11 away from the center of the mounting disk 1, and the slide groove 11 is an arc-shaped groove bulging toward the center direction of the mounting disk 1.

[0085] Also optionally, the first connection portion 221 is engaged in the slide groove 11, and the second connection portion 222 is engaged in the mounting hole 12, and the first connection portion 221 is located on the side of the second connection portion 222 away from the center of the mounting disk 1, and correspondingly, the mounting hole 12 is located on the side of the slide groove 11 close to the center of the mounting disk 1, and the slide groove 11 is an arc-shaped groove that bulges away from the center direction of the mounting disk 1.

[0086] In some embodiments of the present invention, the axis of the crossflow impeller 100 and the axis of the mounting hole 12 form a radial plane, and the slide groove 11 is symmetrically or asymmetrically arranged relative to the radial plane.

[0087] Optionally, the axis of the crossflow impeller 100 and the axis of the mounting hole 12 form a radial plane, and the slide slot 11 is symmetrically arranged relative to the radial plane, that is, the line between the center of the mounting hole 12 and the center of the slide slot 11 is collinear with the line between the center of the mounting hole 12 and the center of the crossflow impeller 100, and the slide slot 11 is symmetrically arranged relative to the line between the center of the mounting hole 12 and the center of the crossflow impeller 100. When the crossflow impeller 100 rotates along the first direction F1 and the second direction F2, the first connecting portion 221 and / or the second connecting portion 222 have the same action when switching between the first position and the second position, thereby improving the motion stability of the movable air guide blade 20.

[0088] Alternatively, the axis of the crossflow fan 100 and the axis of the mounting hole 12 form a radial plane, and the slide slot 11 is asymmetrically arranged relative to the radial plane, that is, the line between the center of the mounting hole 12 and the center of the slide slot 11 is not colinear with the line between the center of the mounting hole 12 and the center of the crossflow fan 100, and the slide slot 11 is asymmetrically arranged relative to the line between the center of the mounting hole 12 and the center of the crossflow fan 100, thereby improving the air outlet effect. In addition, the first connecting portion 221 and / or the second connecting portion 222 are asymmetrical relative to the line between the center of the mounting hole 12 and the center of the crossflow fan 100 when in the first position and the second position, and the movable guide vane 20 can produce different air guiding effects when guiding air in the forward direction and in the reverse direction, thereby further improving the functionality of the crossflow fan 100 of the present invention.

[0089] In some specific embodiments of the present invention, Figure 2 As shown, the first connecting portion 221 and the second connecting portion 222 are both connecting rods, the connecting rods extend into the slide slot 11 and slide in cooperation with the slide slot 11, and the connecting rods extend into the mounting hole 12 and rotate in cooperation with the mounting hole 12. Each connecting rod is arranged along the length direction F3 of the movable air guide blade 20, that is, along the axial direction of the crossflow impeller 100, and the air guide portion 21 is connected between the two connecting rods.

[0090] Correspondingly, if Figure 7 As shown, the limiting rib 13 is arranged on the inner wall of the slide slot 11, and the distance between the limiting rib 13 and the inner wall of the slide slot 11 is less than the width of the slide slot 11. When the connecting rod extends into the slide slot 11 and slides along the extension track of the slide slot 11, the limiting rib 13 can limit the connecting rod, thereby preventing the first connecting portion 221 and / or the second connecting portion 222 from erroneously coming out of the first position or the second position, and improving the working stability of the movable air guide blade 20.

[0091] In some embodiments of the present invention, at least a portion of the air guide portion 21 is a flexible area, and at least a portion of the air guide portion 21 can be deformed to improve the air guiding effect when the movable air guide blades 20 guide the air, thereby increasing the air supply of the crossflow impeller 100 .

[0092] When the crossflow wind wheel 100 rotates along the first direction F1, the connecting portion 22 of the movable air guide blade 20 moves to the first position under the action of centrifugal force, and the movable air guide blade 20 guides the air positively. At the same time, the air guide portion 21 bulges toward the second direction F2 under the action of centrifugal force. The movable air guide blade 20 has a certain curvature as a whole, which improves the air guiding effect, thereby greatly increasing the air supply volume of the crossflow wind wheel 100.

[0093] When the crossflow wind wheel 100 rotates along the second direction F2, under the action of centrifugal force, the connecting portion 22 of the movable guide blade 20 moves to the second position, and the movable guide blade 20 guides the wind in the reverse direction. At the same time, the guide portion 21 bulges toward the first direction F1 under the action of centrifugal force. The movable guide blade 20 has a certain curvature as a whole, which improves the wind guiding effect, thereby greatly increasing the air supply volume of the crossflow wind wheel 100.

[0094] It is understandable that, since the movable air guide blades 20 of the embodiment of the present application need to move to guide the wind in different directions, the movable air guide blades 20 preferably do not have a shape that is curved along the circumference of the crossflow wind wheel 100, so that the movable air guide blades 20 can achieve a better air guiding effect in both directions. When the movable air guide blades 20 are non-deformable parts, when the movable air guide blades 20 are driven by centrifugal force to move to guide the wind in different directions, the straight shape of the movable air guide blades 20 will also result in a lower air volume of the movable air guide blades 20. The air guide portion 21 of the movable air guide blade 20 of the embodiment of the present application is a flexible part, and the air guide portion 21 is deformed under the action of centrifugal force. The air guide portion 21 has a certain curvature as a whole, thereby improving the air guiding effect, so that the air supply volume of the crossflow wind wheel 100 is greatly improved.

[0095] In some specific embodiments of the present invention, the air guide portion 21 is a flexible area, which increases the deformation degree of the movable air guide blade 20 and further improves the air guide effect. Optionally, the air guide portion 21 is a high-density cloth sheet or a drum membrane, and the air guide portion 21 is easily deformed.

[0096] In some further embodiments of the present invention, the air guide portion 21 is a non-deformable member. Optionally, the air guide portion 21 is a curved member with an arc in the thickness direction to improve the air guide effect.

[0097] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the guide blade 2 includes a plurality of first guide blades 2a and a plurality of second guide blades 2b, and the width of the first guide blade 2a is greater than the width of the second guide blade 2b. The lengths of the first guide blade 2a and the second guide blade 2b are the same, so the area of ​​the guide portion 21 of the first guide blade 2a is greater than the area of ​​the guide portion 21 of the second guide blade 2b. By arranging the first guide blade 2a and the second guide blade 2b to cooperate, the airflow at the axis of the crossflow wind wheel 100 can be disturbed, so that the vortex is not easily formed, and the noise of the crossflow wind wheel 100 is reduced. Moreover, the first guide blade 2a and the second guide blade 2b are arranged in coordination with each other, so that the number of guide blades 2 can be increased, and the wind outlet effect of the crossflow wind wheel 100 can be improved.

[0098] In some embodiments of the present invention, the chute 11 includes a first chute 11a matched with the first air guide blade 2a and a second chute 11b matched with the second air guide blade 2b, and the mounting hole 12 includes a first mounting hole 12a matched with the first air guide blade 2a and a second mounting hole 12b matched with the second air guide blade 2b. It can be understood that the two ends of the length direction F3 of the air guide blade 2 are respectively connected to two adjacent mounting plates 1, and the two ends of the width direction F4 of the air guide blade 2 are respectively connected to the same mounting plate 1, and the direction between the first connecting portion 221 and the second connecting portion 222 is the width direction F4 of the air guide blade 2. The width of the first air guide blade 2a is greater than the width of the second air guide blade 2b, that is, the distance between the first chute 11a and the first mounting hole 12a is greater than the distance between the second chute 11b and the second mounting hole 12b.

[0099] In some specific embodiments of the present invention, Figure 8 and Fig. 9 As shown, the first mounting hole 12a and the second mounting hole 12b are arranged at intervals along the circumference of the crossflow wind wheel 100, and the first mounting hole 12a and the second mounting hole 12b are located on the same circular trajectory. The first slide grooves 11a are arranged at intervals along the circumference of the crossflow wind wheel 100, and the second slide grooves 11b are arranged at intervals along the circumference of the crossflow wind wheel 100, and the first slide grooves 11a are located on the side of the second slide grooves 11b away from the center direction of the mounting plate 1.

[0100] In some embodiments of the present invention, the first guide vane 2a and the second guide vane 2b are alternately arranged along the circumferential direction. Correspondingly, the first mounting hole 12a and the second mounting hole 12b are alternately arranged along the circumferential direction, and the first chute 11a and the second chute 11b are alternately arranged along the circumferential direction. The chute 11 is arranged to extend along the circumference of the crossflow wind wheel 100, and the chute 11 occupies a large area. By arranging the first guide vane 2a and the second guide vane 2b, the first chute 11a and the second chute 11b are arranged at intervals in the radial direction, so that the number of guide vanes 2 can be increased, and the air output of the crossflow wind wheel 100 can be increased.

[0101] In some specific embodiments of the present invention, Figure 8 and Fig. 9 As shown, the first guide blades 2a and the second guide blades 2b are alternately arranged in the circumferential direction, that is, one second guide blade 2b is sandwiched between two first guide blades 2a, and one first guide blade 2a is sandwiched between two second guide blades 2b.

[0102] In other embodiments of the present invention, the first guide vanes 2a and the second guide vanes 2b are arranged at other intervals. For example, the first guide vanes 2a and the second guide vanes 2b are alternately arranged along the circumference of the crossflow impeller 100 at a ratio of two to one, which also falls within the protection scope of the present invention.

[0103] Reference below Figure 1-Figure 9 The structure and working process of the crossflow impeller 100 in a specific embodiment of the present invention are described in detail.

[0104] The crossflow wind wheel 100 includes: a mounting plate 1 and a guide vane 2. There are multiple mounting plates 1, and the multiple mounting plates 1 are arranged at intervals along the axial direction of the crossflow wind wheel 100. The two ends of the guide vane 2 in the length direction F3 are connected between two adjacent mounting plates 1. The guide vane 2 includes a first connection portion 221, a second connection portion 222 and a guide portion 21. The first connection portion 221 and the second connection portion 222 are located at the two ends of the width direction F4 of the guide vane 2. The first connection portion 221 and the second connection portion 222 are both configured as connecting rods. The guide portion 21 is a flexible member that can be deformed when subjected to force.

[0105] A slide groove 11 matching with the second connection part 222 is provided on the mounting plate 1, and the slide groove 11 is extended along the circumference of the crossflow wind wheel 100, and the second connection part 222 extends into the slide groove 11 and slidably matches with the slide groove 11. The slide groove 11 and the second connection part 222 are provided one by one, and a plurality of slide grooves 11 are provided in sequence and spaced apart along the circumference of the crossflow wind wheel 100.

[0106] The mounting plate 1 is also provided with mounting holes 12 that match the first connection part 221. The mounting holes 12 are arranged one by one with the first connection part 221. A plurality of mounting holes 12 are arranged in sequence and spaced along the circumference of the crossflow impeller 100. The first connection part 221 extends into the mounting holes 12 and rotates with the mounting holes 12. The mounting holes 12 are located on the side of the slide groove 11 close to the center of the mounting plate 1, and the first connection part 221 is located on the side of the second connection part 222 away from the center of the mounting plate 1. The slide groove 11 is an arc-shaped groove that bulges away from the center of the mounting plate 1.

[0107] The second connection portion 222 has a first position located at the end of the slide slot 11 in the second direction F2 and a second position located at the end of the slide slot 11 in the first direction F1. When the crossflow wind wheel 100 rotates along the first direction F1, under the combined action of centrifugal force and air, the second connection portion 222 slides to the first position of the slide slot 11 at one end of the second direction F2, and at the same time, the wind guide portion 21 bulges toward the second direction F2 under the action of centrifugal force and airflow, and the movable air guide vane 20 guides the air forward; when the crossflow wind wheel 100 rotates along the second direction F2, under the combined action of centrifugal force and air, the second connection portion 222 slides to the second position of the slide slot 11 at one end of the first direction F1, and at the same time, the wind guide portion 21 bulges toward the first direction F1 under the action of centrifugal force and airflow, and the movable air guide vane 20 guides the air in the reverse direction. The movable air guide vane 20 can guide the air in different directions.

[0108] In some embodiments of the present invention, there are multiple mounting disks 1 and they are spaced apart along the axial direction of the crossflow wind wheel 100. The movable guide vanes 20 are connected between two adjacent mounting disks 1, and both sides of the mounting disks 1 on the axial direction of the crossflow wind wheel 100 can be used to connect the movable guide vanes 20.

[0109] Optionally, the slide groove 11 and the mounting hole 12 are arranged on the mounting plate 1 without being through, and the first connection portion 221 and the second connection portion 222 on both sides of the axial direction of the crossflow impeller 100 are respectively arranged in the corresponding slide groove 11 and the mounting hole 12. The slide grooves 11 and the mounting holes 12 on both sides of the axial direction of the crossflow impeller 100 can be arranged asymmetrically.

[0110] Alternatively, the slide slot 11 and the mounting hole 12 are arranged through the mounting plate 1, and one slide slot 11 can simultaneously accommodate two second connection parts 222 on both sides of the axial direction of the crossflow impeller 100, and the first mounting hole 12a can simultaneously accommodate two first connection parts 221 on both sides of the axial direction of the crossflow impeller 100. The dimension of the second connection part 222 extending into the slide slot 11 is less than half of the depth of the slide slot 11, and the dimension of the first connection part 221 extending into the mounting hole 12 is less than half of the depth of the mounting hole 12, thereby improving motion interference and enhancing the motion stability of the movable air guide.

[0111] A crossflow blower according to a second aspect of the present invention comprises any one of the crossflow blower wheels 100 described above.

[0112] like Figure 1 and Fig.10 As shown, the crossflow wind wheel 100 includes a plurality of mounting disks 1, and a central axis 5 is arranged along the axial direction of the crossflow wind wheel 100. The central axis 5 connects all the mounting disks 1 to each other, and the central axis 5 is arranged at the center of the mounting disk 1, and the axis of the central axis 5 is colinear with the axis of the mounting disk 1.

[0113] The crossflow fan further includes a motor, which is used to drive the crossflow fan wheel 100 to rotate along the first direction F1 or along the second direction F2. Figure 1 and Fig.10 As shown, a bearing mounting shaft 3 is provided at one axial end of the crossflow rotor 100, and a motor shaft mounting hole 4 is provided on the mounting plate 1 at the other axial end of the crossflow rotor 100.

[0114] According to the cross flow blower of the present invention, by providing the cross flow blower wheel 100, the cross flow blower can supply air in two directions, and the functionality is improved.

[0115] The air conditioner according to the third aspect of the present invention includes any of the cross-flow fans described above. Only one cross-flow fan is required to realize air supply in two directions, thereby increasing the air supply range and reducing the structural complexity and manufacturing cost of the air conditioner.

[0116] In some embodiments, the air conditioner has a first air outlet and a second air outlet. When the crossflow fan wheel 100 of the crossflow fan rotates along the first direction F1, the air conditioner discharges air through the first air outlet, and no air flows out of the second air outlet; when the crossflow fan wheel 100 of the crossflow fan rotates along the second direction F2, the air conditioner discharges air through the second air outlet, and no air flows out of the first air outlet. The air conditioner using the crossflow fan of the embodiment of the present invention realizes two-way air supply, and each direction independently supplies air, thereby increasing the air supply range of the air conditioner and improving the airflow coverage area of ​​the air conditioner. In addition, the air conditioner only needs to be provided with one crossflow fan to realize two-way air supply, which can reduce the structural complexity and manufacturing cost of the air conditioner.

[0117] In other embodiments, the air conditioner has an air inlet and an air outlet. When the crossflow fan wheel 100 of the crossflow fan rotates along the first direction F1, the air conditioner is in a normal air supply mode with air entering the air inlet and air exiting the air outlet; when the crossflow fan wheel 100 of the crossflow fan rotates along the second direction F2, the air conditioner is in a reverse air supply mode with air entering the air outlet and air exiting the air inlet. The directions of the air inlet and the air outlet are different, so the air conditioner using the crossflow fan wheel 100 of the embodiment of the present invention realizes two-way air supply, improves the air flow coverage area of ​​the air conditioner, and the air conditioner only needs to be provided with one crossflow fan to realize two-way air supply, which can reduce the structural complexity and manufacturing cost of the air conditioner. When the air inlet is set at the top of the air conditioner and the air outlet is set at the bottom of the air conditioner, the air conditioner of the embodiment of the present invention can also output cooling airflow from the top and heating airflow from the bottom, thereby improving the comfort of cooling and heating of the air conditioner. In addition, the switching of the air flow direction between the air inlet and the air outlet can also realize reverse blowing and dust removal, thereby improving the cleanliness of the air conditioner.
