As shown in fig. 1, the present invention provides an air blowing mechanism 10, and the air blowing mechanism 10 includes a main air blowing duct 100, a main air blowing device 200, a sub air blowing duct 300, and a sub air blowing device 400.
As shown in fig. 1, the main air supply duct 100 is formed with an air supply duct 110 and a sub air supply port 120 communicating with the air supply duct 110. That is, the main blowing duct 100 is formed with a blowing passage 110 and the main blowing duct 100 further includes a sub blowing port 120 formed on the main blowing duct 100 and communicating with the blowing passage 110. Optionally, the air supply duct 110 further includes a main air outlet 130 at one end of the main air supply duct 100. Alternatively, the secondary air supply outlet 120 may be located on the inner wall surface 111 of the main air supply duct 100, or may be disposed to protrude from the inner wall surface 111, which is not limited herein.
As shown in fig. 3 and 4, the main blower 200 is disposed corresponding to the main blower duct 100, and the main blower 200 is rotatable in a first direction, so that the main airflow can be driven to rotate in the first direction and be discharged through the blower passage 110.
Optionally, the main air supply element 200 may be a rotating impeller disposed at an end of the air supply channel 110 away from the main air outlet 130, and when the main air supply element 200 rotates around the first direction, the main air flow is driven to rotate along the first direction and is discharged through the air supply channel 110.
In the embodiment, the secondary air supply outlet 120 is located between the main air supply member 200 and the main air outlet 130.
As shown in fig. 4, the main air flow may be discharged from the air supply duct 110 in a spiral rotating path, and the overall direction of the main air flow may be divided into a direction rotating in the first direction and a direction facing the main outlet 130.
As shown in fig. 1 and 2, one end of the secondary air supply duct 300 is connected to the secondary air supply outlet 120 of the main air supply duct 100; the sub blowing unit 400 is disposed corresponding to the sub blowing duct 300.
The secondary blower 400 may drive the secondary airflow through the secondary blower duct 300 and discharge the secondary airflow through the secondary blower port 120 to form a mixed airflow with the primary airflow. The vorticity of the mixed gas stream is less than or greater than the vorticity of the primary gas stream.
In a specific scenario, the direction of the secondary air flow discharged from the secondary air supply opening 120 and the secondary air supply duct 300 and the secondary air supply opening 120 are all related, the secondary air flow driven by the secondary air supply member 400 is discharged under the combined action of the secondary air supply duct 300 and the secondary air supply opening 120, and can be mixed with the primary air flow to form a mixed air flow, and the mixed air flow can also be discharged through the air supply passage 110. That is, the mixed air flow is formed by mixing the main air flow driven by the main blower 200 and the sub air flow discharged from the sub air outlet 120.
In an alternative embodiment, the swirl of the combined air flow is less than the swirl of the primary air flow.
In an alternative embodiment, the swirl of the combined air flow is greater than the swirl of the primary air flow.
In an alternative embodiment, the vorticity of the primary airflow may determine the extent to which the primary airflow is spread outward when exiting the main outlet 130. That is, the swirl of the main air flow can determine the blowing range of the main air flow sent out from the blowing passage. As used herein, the overall direction of the primary air flow may be specifically divided into a direction rotating in the first direction and a direction toward the main outlet 130. The speed in the direction of rotation in the first direction may be expressed as a swirl, and when the speeds in the directions toward the main outlet 130 are uniform, the main air flow having a relatively large swirl may be more favorably diffused outward than the main air flow having a relatively small swirl when discharged from the main outlet 130, that is, the main air flow having a relatively large swirl may be supplied over a wider range than the main air flow having a relatively small swirl.
In the present application, the secondary air flow and the primary air flow are mixed to form the mixed air flow, and when the vorticity of the mixed air flow is smaller than that of the primary air flow, the diffusivity of the mixed air flow discharged from the main air outlet 130 is relatively reduced, so that the air supply range of the whole air supply mechanism 10 can be reduced. When the swirl of the mixed airflow is greater than the main airflow, the diffusion of the mixed airflow discharged from the main air outlet 130 is relatively increased, so as to increase the air supply range of the whole air supply mechanism 10.
In the above embodiment, the secondary air blowing port 120 communicating with the air blowing duct 110 is provided in the main air blowing duct 100, and the secondary air blowing duct 300 communicating with the secondary air blowing port 120 and the secondary air blowing member 400 provided in the secondary air blowing duct 300 are provided, so that the secondary air flow is driven by the secondary air blowing member 400 to pass through the secondary air blowing duct 300 and the secondary air blowing port 120 and then mixed with the main air flow to form the mixed air flow, and the rotation degree of the mixed air flow can be larger than the rotation degree of the main air flow or smaller than the rotation degree of the main air flow, thereby increasing the air blowing range of the entire air blowing mechanism 10 or reducing the air blowing range of the entire air blowing mechanism 10. And further, since the sub air flow is further provided through the sub air supply duct 300 and the sub air supply opening 120, the air volume of the mixed air flow can be increased, so that the air supply range of the air supply mechanism 10 can be increased or reduced, and at the same time, the air supply volume can be increased or not reduced.
In an alternative embodiment, the secondary blowing direction of the secondary blowing port 120 and the rotation direction of the main airflow at the secondary blowing port 120 are greater than or equal to 0 degree and less than 90 degrees, and may be specifically 0 degree, 60 degrees, or 89 degrees, and the like. Here, the rotation direction of the main air flow in the present embodiment is a tangential direction of the main air flow at the secondary air blowing port 120 when the main air flow rotates in the first direction. Since the secondary blowing direction of the secondary blowing port 120 and the tangential direction are greater than or equal to 0 degrees and less than 90 degrees, that is, the secondary blowing direction of the secondary blowing port 120 and the direction of the main airflow are mutually enhanced, the secondary airflow has an enhancement effect on the rotation of the main airflow after passing through the secondary blowing port 120, that is, the rotation of the mixed airflow of the secondary airflow and the main airflow through the secondary blowing port 120 is greater than that of the main airflow.
In a specific scenario, when the secondary blowing direction of the secondary blowing port 120 is 0 degrees to the rotation direction of the main airflow at the secondary blowing port 120, that is, the secondary blowing direction of the secondary blowing port 120 is the same as the tangential direction of the main airflow at the secondary blowing port 120, the secondary airflow will form an airflow in the same direction as the rotation direction of the main airflow under the guiding action of the inner wall surface 111 of the main blowing duct 100 after coming out of the secondary blowing port 120.
In another alternative embodiment, the secondary air blowing direction of the secondary air blowing opening 120 and the rotation direction of the main air flow at the secondary air blowing opening 120 are greater than 90 degrees and less than or equal to 180 degrees, and may specifically be 91 degrees, 100 degrees or 180 degrees. Since the secondary air blowing direction of the secondary air blowing opening 120 and the tangential direction are greater than 90 degrees and less than or equal to 180 degrees, that is, the secondary air blowing direction of the secondary air blowing opening 120 and the direction of the main air flow are mutually reduced, the secondary air flow has a reduction effect on the rotation of the main air flow after passing through the secondary air blowing opening 120, that is, the rotation of the mixed air flow of the secondary air flow and the main air flow is smaller than the rotation of the main air flow.
In other embodiments, the secondary blowing direction of the secondary blowing port 120 may be further divided into a second direction toward the main blowing port 130 and a third direction perpendicular to the second direction, the third direction being parallel to a rotation plane on which the main airflow rotates in the first direction.
In an alternative embodiment, the rotation direction of the main airflow at the secondary air supply outlet 120 and the secondary air supply direction in the third direction are greater than or equal to 0 degrees and less than 90 degrees, and the rotation degree of the mixed airflow can be greater than that of the main airflow.
Optionally, the secondary air supply direction of the secondary air supply outlet 120 may be the same as the overall direction of the main air flow. That is, the overall direction of the main air flow is a spiral direction, and the secondary air flow direction of the secondary air outlet 120 may be a similar spiral direction, so that the vorticity of the mixed air flow of the secondary air flow and the main air flow discharged from the secondary air outlet 120 is greater than that of the main air flow.
In another alternative embodiment, the rotation direction of the secondary air blowing direction in the third direction and the rotation direction of the primary air flow at the secondary air blowing opening 120 are greater than 90 degrees and less than or equal to 180 degrees, and the rotation degree of the mixed air flow can be less than that of the primary air flow.
As shown in fig. 5, the number of the secondary air supply ducts 300 is multiple, and the secondary air supply opening 120 is also provided with multiple secondary air supply ducts 300, in alternative embodiments, the secondary air supply opening 120 may correspond to one secondary air supply duct 300, or correspond to multiple secondary air supply ducts 300, or one secondary air supply duct 300 may correspond to multiple secondary air supply openings 120, which is not limited herein.
Among them, the sub-blowing direction of some sub-blowing ports 120 among the plurality of sub-blowing ports 120 is the same as the rotation direction of the main air flow at the sub-blowing ports 120, and the sub-blowing direction of the other sub-blowing ports 120 is opposite to the rotation direction of the main air flow at the sub-blowing ports 120.
In the exemplary embodiment, the secondary air flow from some of the plurality of secondary air ports 120 is mixed with the primary air flow to form a mixed air flow having a higher vorticity than the primary air flow.
In other embodiments, the secondary air flow from another part of the secondary air outlets 120 of the plurality of secondary air outlets 120 is mixed with the primary air flow to form a mixed air flow with a smaller vorticity than the primary air flow.
In a specific scenario, the number of the secondary air outlets 120 may be two, and one of the secondary air flows is mixed with the primary air flow to form a mixed air flow with a higher rotation degree than the primary air flow. The other of the secondary air flows is mixed with the primary air flow to form a mixed air flow with a smaller vorticity than the primary air flow.
In other embodiments, the number of the secondary air supply outlets 120 may be other numbers, which are not limited herein.
In an alternative embodiment, the plurality of secondary air supply vents 120 are symmetrically disposed with respect to the rotational center of the primary air flow.
In other embodiments, a plurality of secondary air supply ports 120 are provided at intervals in the axial and/or circumferential direction of the air supply passage 110. As a concrete example, the plurality of sub-air blowing ports 120 may be provided at intervals in the circumferential direction at the same axial position. Or, a plurality of secondary air blowing ports 120 may be provided at the same circumferential position at intervals in the axial direction, which is not limited herein.
As shown in fig. 2, the air supply mechanism 10 further includes a main duct 500, and the main duct 500 may communicate with a plurality of sub-supply ducts 300. Wherein, the sub blowing member 400 may be provided on the main duct 500.
Alternatively, by providing the main duct 500 and providing the sub blowing members 400 on the main duct 500, it is possible to realize that one sub blowing member 400 provides the sub air flow to all the sub blowing ducts 300, so as to reduce the cost.
As shown in fig. 2, each air supply duct 300 is provided with a valve 310.
Optionally, by setting the valve 310 and controlling the on/off of the valve 310, the secondary airflow for increasing the rotation degree or the secondary airflow for reducing the rotation degree can be effectively controlled to be provided for the primary airflow, so as to control the air supply range of the air supply mechanism 10 to be increased or decreased. And further, the number of the sub blowing ports 120 for supplying the sub air stream may be controlled, thereby controlling the extent of increase or decrease of the blowing range, etc.
In an embodiment, the secondary blower 400 may be an adjustable driving motor, so that the power of the driving motor is adjusted to adjust the speed and the air volume of the secondary air flow discharged from the secondary blower 120, so that the air supply range can be controlled to be increased or decreased by itself or in cooperation with the valve 310.
In a specific scenario, as shown in fig. 6, the secondary air blower 400 is an air pump with adjustable power, and when the valve 310 of the secondary air supply duct 300 corresponding to the secondary air flow providing the increased rotation degree for the primary air flow is in an open state and the valve 310 of the secondary air supply duct 300 corresponding to the secondary air flow providing the decreased rotation degree for the primary air flow is in a closed state, the power of the air pump is increased to effectively increase the speed and the air volume of the secondary air flow, thereby effectively increasing the rotation degree of the mixed air and further increasing the range of the air supply mechanism 10. Conversely, decreasing the power of the air pump decreases the speed and volume of the secondary air flow, thereby decreasing the rotation of the mixture and decreasing the range of the air supply mechanism 10.
In another specific scenario, as shown in fig. 7, when the valve 310 of the secondary air supply duct 300 corresponding to the secondary air flow providing the increased rotation degree to the primary air flow is in the closed state and the valve 310 of the secondary air supply duct 300 corresponding to the secondary air flow providing the decreased rotation degree to the primary air flow is in the open state, increasing the power of the air pump can effectively increase the speed and the air volume of the secondary air flow, thereby effectively decreasing the rotation degree of the air mixture and further increasing the air supply range reduction range of the air supply mechanism 10. Conversely, decreasing the power of the air pump decreases the speed and volume of the secondary air flow, thereby increasing the rotation of the mixed air and decreasing the extent of decrease in the blowing range of the blowing mechanism 10.
The following working process is explained with respect to the above structure:
when the main blower 200 is in operation, the main airflow is sent out from the main outlet 130 through the blower passage 110. The operation of the secondary air blowing elements 400 is performed such that the main duct 500 provides the secondary air flows to the plurality of secondary air blowing elements 400, and in the first scenario, when the valve 310 of the secondary air blowing duct 300 corresponding to the secondary air flow providing the increased rotation degree to the main air flow is in the open state and the valve 310 of the secondary air blowing duct 300 corresponding to the secondary air flow providing the decreased rotation degree to the main air flow is in the closed state, the secondary air flow is discharged from the secondary air blowing duct 300 corresponding to the secondary air flow providing the increased rotation degree to the main air flow and the main air flow to form a mixed air flow, and the mixed air flow is continuously blown out from the main air outlet 130 through the air blowing duct 110, because the rotation degree of the mixed air flow is greater than the rotation degree of the original main air flow, the air blowing range of the whole air blowing mechanism 10 is increased. In the second scenario, that is, when the valve 310 of the secondary air supply duct 300 corresponding to the secondary air flow providing the increased rotation degree to the main air flow is in the closed state and the valve 310 of the secondary air supply duct 300 corresponding to the secondary air flow providing the decreased rotation degree to the main air flow is in the open state, the secondary air flow is discharged through the secondary air supply duct 300 corresponding to the secondary air flow providing the decreased rotation degree to the main air flow and the secondary air supply outlet 120 to form a mixed air flow with the main air flow, and the mixed air flow is continuously sent out from the main air outlet 130 through the air supply duct 110, the rotation degree of the mixed air flow is smaller than that of the original main air flow, so that the air supply range of the entire air supply mechanism 10 is reduced.
As shown in fig. 8, the present application also provides an air conditioner 1, where the air conditioner 1 includes the air supply mechanism 10 in any of the above embodiments.
In an embodiment, the air conditioner 1 may further include a cooling mechanism (not shown) and/or a heating mechanism (not shown), wherein the cooling mechanism is configured to provide a cool airflow to the air supply mechanism 10 and send the cool airflow out through the main outlet 130 of the air supply mechanism 10. The heating mechanism is used for providing hot air flow to the air supply mechanism 10 and sending out the hot air flow through the main air outlet 130 of the air supply mechanism 10.
As described above, according to the air blowing mechanism and the air conditioner of the present invention, the sub air blowing port 120 communicating with the air blowing duct 110 is provided in the main air blowing duct 100, and the sub air blowing duct 300 communicating with the sub air blowing port 120 and the sub air blowing member 400 provided in the sub air blowing duct 300 are provided, and the sub air flow is driven by the sub air blowing member 400 to pass through the sub air blowing duct 300 and the sub air blowing port 120 and then mixed with the main air flow to form the mixed air flow, and since the rotation of the mixed air flow can be larger than the rotation of the main air flow or smaller than the rotation of the main air flow, the air blowing range of the entire air blowing mechanism 10 can be increased or decreased. And further, since the sub air flow is further provided through the sub air supply duct 300 and the sub air supply opening 120, the air volume of the mixed air flow can be increased, so that the air supply range of the air supply mechanism 10 can be increased or reduced, and at the same time, the air supply volume can be increased or not reduced. Furthermore, by setting the valve 310 and controlling the on/off of the valve 310, the secondary airflow for increasing the rotation degree or the secondary airflow for decreasing the rotation degree can be effectively controlled to be provided for the main airflow, so as to control the air supply range of the air supply mechanism 10 to be increased or decreased. And further, the number of the sub blowing ports 120 for supplying the sub air stream may be controlled, thereby controlling the extent of increase or decrease of the blowing range, etc. And further, the secondary air supply member 400 is set as an adjustable driving motor, so that the speed and the air volume of the secondary air flow discharged from the secondary air supply outlet 120 are adjusted by adjusting the power of the driving motor, and the increase or decrease of the air supply range can be controlled independently or in cooperation with the valve 310.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent results or equivalent flow transformations performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
