Description

  The present invention purifies the blower that is installed in a living room, such as a fan used to reduce the temperature of sensation due to direct airflow and the circulation of air in the room, and the air taken into the blower, and blows the purified air. The present invention relates to an air cleaning device with an air blowing function that purifies indoor air.

  Conventionally, this type of air blower has an impeller and a motor enclosed in a base that serves as a base, and air is circulated from the annular air blower provided in the upper part of the base so that the air is blown horizontally to the floor surface. In addition, home blowers that generate air flow are known.

  Hereinafter, the blower will be described with reference to FIGS. 9 and 10.

  FIG. 9 is a perspective view of the blower assembly 100, and FIG. 10 is a sectional view of the base 116.

  The blower assembly 100 has an annular nozzle 101 that defines a central opening 102. The annular nozzle 101 has a port 112 and extends about an axis X to form a central opening 102 that allows the blower assembly 100 to draw external air into the air flow discharged from the port 112. The annular nozzle 101 is arranged so that the airflow is directed along the surface thereof and the airflow is directed in the direction of the axis X. The surface of the annular nozzle 101 is a tapered diffuser portion 132 that moves away from the axis X toward the downstream side of the airflow. And a guide portion 133 that is located on the downstream side as viewed from the diffuser portion 132 and that forms an angle with respect to the diffuser portion 132 at a wider angle than the tapered shape.

  Further, as shown in FIG. 10, the blower assembly 100 includes a motor 122 that generates an air flow inside a base portion 116 disposed at a lower portion, and a motor rotating shaft 123 that extends vertically downward from the motor 122. The impeller (impeller) 130 is coupled to the motor 122, and the motor 122 is connected to an electrical connection unit and a power source. A plurality of air volume selection buttons 120 allow the user to operate the blower assembly 100.

  Further, the blower assembly 100 includes a swing mechanism 140 including a swing shaft 142 connected to the casing lower portion 117 of the base 116 below the base 116. The base 116 is connected only to the swing mechanism 140 and the swing shaft 142, and the swing mechanism 140 is connected to the swing motor 141 by a coupling plate 143 including a crank arm mechanism. Similar to the motor 122, the swing motor 141 is also connected to an electrical connection unit and a power source, and a plurality of swing selection buttons 144 allow the user to operate the swing operation of the blower assembly 100.

  With the above configuration, the blower assembly 100 operates as follows.

  When the user selects an arbitrary button from the plurality of air volume selection buttons 120 shown in FIG. 9 and the motor 122 is activated, air is sucked into the blower assembly 100 through the air inlet 124 shown in FIG. It is. The air is pressurized by an impeller (impeller) 130, sent to the annular nozzle 101 through the internal passage 110, and discharged from the mouth 112 as a primary air flow. At this time, the primary air flow is directed in the direction of the axis X by flowing along the surface of the diffuser portion 132. In addition, the primary air flow draws in the outside air around the mouth 112 and is accompanied by a secondary air flow generated by drawing in the air around the outer edge of the annular nozzle by the movement of the outside air, and from the central opening 102. Releases all air flow in the direction of axis X. The user can arbitrarily select the air volume discharged from the blower assembly 100 by the air volume selection button 120.

  In addition, the blowing range of the air flow discharged from the blower assembly 100 is limited by the area range of the central opening 102 in the direction of the axis X. Here, the user selects any of the swing selection buttons 144 shown in FIG. When the button is selected, the swing mechanism 140 is driven, that is, when the swing motor 141 is activated, the swing shaft 142 connected to the swing motor 141 via the coupling plate 143 including the crank arm mechanism rotates. Thus, the blower assembly 100 above the base portion 116 rotates about the axis Y, that is, the blower range rotates in the horizontal direction around the axis Y, so that the user can arbitrarily adjust the blower range. (For example, refer to Patent Document 1).

JP 2010-203450 A

  In such a conventional blower, the primary air flow is discharged from the mouth of the annular nozzle, so that the secondary air flow is drawn into the external environment, especially the area around the mouth and the outer edge of the annular nozzle. Since the whole air flow is generated, the blowing direction of the whole air flow is limited to the direction of the axis X through which the primary air flow flows, and the blowing range of the air flow is in the area range of the central opening 102 in the direction of the axis X. Since it is limited, an air flow can be provided in a wide range by providing a swing mechanism as in Patent Document 1, but a motor is required for the swing mechanism, and the swing mechanism itself becomes large and heavy, There was a problem that carrying around became complicated.

  In addition, since the blower assembly 100 rotates about the axis Y, there is a problem that a movable object becomes an obstacle in the daily life space in the living room.

  The air blower according to claim 1 of the present invention comprises a suction port for taking air into the housing, at least one impeller for generating high-pressure air, and at least one motor for driving the impeller. And a plurality of nozzles erected from one surface of the housing, wherein the nozzles are arranged on one side of the high-pressure air generator in a direction perpendicular to the direction in which the nozzles are erected. A blowout port for blowing out the generated high-pressure air, and a duct for guiding high-pressure air to the blowout port inside the nozzle, wherein the nozzle has a vertical section in the blowout direction, and a plurality of Each of the nozzles provided in the nozzle is provided with a gap so that the nozzles are flush with each other, and the plurality of nozzles are directed outward from the center of the housing toward the outside. The air blower is provided with a wide angle so as to be drawn, and an air drafting path for air attracted to the air blown out from the air outlet is formed by the gap, wherein the high-pressure air generator and the nozzle A flow rate adjustment unit capable of adjusting the flow rate of the high-pressure air, and a flow rate distribution control so that a distribution of the air flow blown from the plurality of nozzles is formed around one nozzle in the flow rate adjustment unit Means.

  As a result, the flow rate distribution control means controls the flow rate adjusting unit, and when the distribution of the air flow blown out from each of the plurality of nozzles is formed around one nozzle, the primary air blown out from the nozzle having the largest blown air flow rate. Since the attraction force that draws the surrounding air into the flow is the largest, the air flow that is blown out from the nozzle having a small blown air flow rate is attracted, and the entire air flow is drawn to the side of the nozzle that has a large blown air flow rate.

  At this time, when the flow rate of air blown from any one of the nozzles at both ends among the plurality of nozzles becomes the largest, the primary air flow blown by the nozzle becomes the main flow, and the air flow blown by other nozzles is attracted. At the same time, the direction component of the air flow blown out by the other nozzles is combined with the direction component of the main flow, so that the entire air flow is blown further outward than the nozzle blowing direction, thereby moving the housing. It is possible to adjust the air blowing range. Here, the total air flow includes a primary air flow blown by the nozzle and a secondary air flow caused by ambient air drawn by the primary air flow.

  Further, in the blower according to claim 2 of the present invention, the nozzle includes an inflow port into which the high-pressure air generated in the high-pressure air generation unit flows, and the flow rate adjustment unit controls the air flow rate into the inflow port. It is an inflow opening variable damper mechanism that can be adjusted.

  As a result, the flow rate distribution control means variably controls the opening degree of the inlet by the variable inlet damper mechanism provided at the inlet of each nozzle. That is, the inlet of the nozzle for which the air flow rate is desired to be maximized is fully opened, and the opening of the inlet is controlled stepwise to form a distribution of airflows blown from a plurality of nozzles.

  At this time, since the flow rate adjusting unit is stored inside the housing, the air blowing range can be adjusted without impairing the appearance.

  Further, in the blower device according to claim 3 of the present invention, the air outlet of the nozzle is a rectangle having a predetermined width, and the flow rate adjusting unit can adjust the width of the air outlet of the nozzle. It is a damper mechanism.

  Thus, the flow rate distribution control means variably controls the width of the air outlet by the nozzle width variable damper mechanism provided at the air outlet of each nozzle. That is, the distribution of the air flow discharged from a plurality of nozzles is formed by fully opening the nozzle outlet for which the air flow rate is desired to be maximized and controlling the outlet width in stages.

  At this time, since the distribution of the air flow blown out from each of the plurality of nozzles can be formed around one nozzle also by the variable nozzle width damper mechanism, the direction component of the blown air flow can be adjusted to make it wider. The air blowing range can be adjusted.

  According to a fourth aspect of the present invention, the high-pressure air generating unit includes a plurality of air blowing means including one impeller and one motor, and individually controls the plurality of air blowing means. It is characterized by having a ventilation control means for performing.

  Thereby, the air blowing control means can be controlled to increase the output of the air blowing means in the vicinity of the nozzle for which the air flow rate is desired to be increased and to reduce the output of the air blowing means in the vicinity of the nozzle for which the air flow rate is desired to be reduced.

  At this time, by coordinating with the flow rate adjusting unit and the flow rate distribution control means, the degree of distribution of the air flow to be blown out can be adjusted to be larger, and the blowing range can be adjusted in a wider range.

  Further, by adjusting the output of the air blowing means in accordance with the air volume desired to be obtained, waste of power consumption can be eliminated and the noise can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In addition, in order to avoid duplication, the same code | symbol is attached | subjected about the same site | part through all drawings, and the description after the 2nd is abbreviate | omitted.
(Embodiment 1)
Hereinafter, the configuration of Embodiment 1 of the present invention will be described in detail with reference to FIGS. 1 and 5A to 5C.

  First, the basic structure of the air blower 1 of this Embodiment 1 is demonstrated.

  As shown in FIG. 1, the blower device 1 according to the first embodiment includes a plurality of nozzles 3 of equal length (six in this embodiment) that are erected from the entire upper surface of the housing 2. Is raised from the upper surface of the housing 2.

  As shown in FIGS. 2 and 3, the housing 2 includes a suction port 4 for taking air into the housing 2, an impeller 5 for generating high-pressure air, a motor 6 for driving the impeller 5, and an impeller. A high-pressure air generation unit 8 configured with a casing 7 is provided, and a chamber space 9 for diverting the high-pressure air generated by the high-pressure air generation unit 8 to the plurality of nozzles 3 is provided.

  The nozzle 3 includes a duct 10 inside and an inlet 11 at the bottom, and the inlet 11 and the chamber space 9 communicate with each other. The high-pressure air generated by the high-pressure air generator 8 passes through the chamber space 9. Thus, it can flow into the duct 10 through the inlet 11.

  3 passes through the duct 10 in one direction perpendicular to the direction in which the nozzle 3 is erected on one side of the nozzle 3 located on the front surface (left side in FIG. 2) of the blower 1 shown in FIG. It has a blowout port 12 for blowing out the high-pressure air.

  As shown in FIG. 4 in plan view, the nozzle 3 has a vertically long cross section in the blowing direction with respect to the direction in which the nozzle 3 is erected. The plurality of nozzles 3 are provided with gaps so that the air outlets 12 are flush with each other, and the air induction air passage 21 that is attracted by the air flow blown out from the air outlets 12 is formed by the gaps. It is formed outside. That is, since six nozzles 3 are provided in the first embodiment, five induction air passages 21 can be formed in the gaps sandwiched between the nozzles 3, one less than the number of nozzles 3.

  The length of the gap is not less than the length of the nozzle 3 in the direction perpendicular to the blowing direction (width of the nozzle 3) in the direction perpendicular to the direction in which the nozzle 3 is erected. In order to obtain uniform wind speed, the length of the nozzle 3 is 30 mm and the length of the nozzle 3 in the standing direction is an example in the first embodiment. The length of the gap is 100 mm, the length of the nozzle 3 in the blowing direction is 200 mm.

  In the first embodiment, the cross-sectional shape in the direction perpendicular to the direction in which the nozzle 3 of the nozzle 3 is erected is a rectangular shape, but it may be vertically long in the blowing direction, and may be another shape such as an ellipse. .

  Further, as shown in FIG. 4, the plurality of nozzles 3 have a wide angle with the air blowing direction away from the center nozzle 3 toward the nozzles 3 provided on the outside from the center of the housing 2. It is prepared to spread.

  In the vicinity of the air outlet 12 in the nozzle 3, as shown in FIG. 2, an air direction adjusting rib 23 that adjusts the air direction in the standing direction of the nozzle 3 is provided.

  Here, the plurality of nozzles 3 indicates three or more.

  Further, the uniformity of the wind speed refers to the wind speed distribution in the surface direction of the total air flow in which a primary air flow 24 and a secondary air flow 25, which will be described later, are joined. It is intended that the wind speed distribution observed in a predetermined range of the viewing plane is within a certain range. That is, the minimum wind speed in the predetermined range of the plane is allowed up to at least half of the maximum wind speed.

  Moreover, high pressure air shall show the air above atmospheric pressure.

  Next, the basic operation of the blower device 1 according to the first embodiment will be described.

  That is, according to the above configuration, when the blower 1 is operated, the motor 6 is driven in the high-pressure air generator 8 and the impeller 5 in the impeller casing 7 is rotated, so that the room air is blown from the suction port 4. While being taken into the apparatus 1 and pressurized, it becomes high-pressure air, and flows out into the chamber space 9 as indicated by an internal flow 22.

  Since the chamber space 9 communicates with all of the plurality of inlets 11 of the plurality of nozzles 3 and the inlets 11 have the same opening area, the high-pressure air is divided into almost the same amount to the plurality of ducts 10, respectively. The air flow in the standing direction of the nozzle 3 is adjusted by a wind direction adjusting rib 23 provided in the vicinity of the air outlet 12 after passing through the duct 10, and is discharged from the air outlet 12 as a primary air flow 24.

  As shown in FIG. 1, the primary air flow 24 attracts the air outside the induction air passage 21 and the outermost nozzle 3, resulting in a secondary air flow 25. The primary air flow 24 and the secondary air flow 25 are merged in front of the blowing device 1 in the blowing direction to form a total air flow, which can be blown as a surface air with a substantially uniform wind speed in a wide range.

  At this time, since the impeller 5 is included in the housing 2, the user cannot make contact with the outside, so that anxiety due to contact can be eliminated.

  In addition, the nozzle 3 is arranged with a gap so that the air outlet 12 is flush, so that the airflow to be blown becomes a surface airflow.

  Moreover, since the wind direction adjustment rib 23 can expand the wind direction in the standing direction of the nozzle 3 by adjusting the elevation angle, it can blow air over a wider range than the length in the standing direction of the nozzle 3. In other words, the air can be blown above the height of the blower 1.

  Next, a configuration for adjusting a particularly important air blowing range in the first embodiment will be described.

  As shown in FIG. 5, in the blower device 1 of the first embodiment, the inflow opening variable damper mechanism 31 that can change the opening area of the inflow port 11 in the inflow port 11 of each nozzle 3 as a flow rate adjustment unit 30 is provided in the chamber. It is provided in the space 9.

  The inflow opening variable damper mechanism 31 includes an opening adjustment plate 32, an adjustment plate motor unit 33 that drives the opening adjustment plate 32, and a flow rate distribution control unit 34 that controls driving of the adjustment plate motor unit 33. 5A to 5C show the opening position of the opening adjusting plate 32 for each nozzle and 3. In the figure, the white display portion indicates the opening position.

  In the blower device 1 of the first embodiment, the adjustment plate motor unit 33 is driven by the flow rate distribution control unit 34, the position of the opening adjustment plate 32 is variably controlled, and the blowing range is the range of the blowing range u shown in the drawing, The range of the ventilation range v and the range of the ventilation range w are adjusted.

  In the example of the first embodiment, the opening adjustment plate 32 is a sheet-like flexible material (for example, cloth or film) having openings at predetermined positions, and the opening adjustment plates 32 are wound around both ends of the opening adjustment plate 32. An adjusting plate motor unit 33 that rotates while being provided is provided, and the adjusting plate motor unit 33 is controlled by a flow rate distribution control unit 34.

  5A to 5C show the position of the opening adjustment plate 32 and the blowing range when adjusting the blowing range.

  FIG. 5A shows the position of the opening adjustment plate 32 in the air blowing range u at the intermediate position. At this time, since the opening areas of the inlets 11 of the nozzles 3 are equally open, the high-pressure air is divided into almost the same amount to the plurality of ducts 10 to obtain a uniform surface airflow when the blower 1 is viewed from the front. be able to.

  FIG. 5B shows the position of the opening adjustment plate 32 in the air blowing range v.

  This is because the flow rate distribution control unit 34 drives and rotates the adjustment plate motor unit 33 in the + direction of the axis S to wind up the opening adjustment plate 32, and drives the adjustment plate motor unit 33 in the − direction of the axis S. Although it is not, it is the state formed by the opening adjustment board 32 which was wound around being pulled out.

  At this time, the opening adjustment plate 32 reduces the opening degree of the inlet 11 of each nozzle 3 from the positive direction of the axis S to the negative direction in a stepwise manner, whereby each inlet 11 from the positive direction of the axis S to the negative direction. The flow rate of the high-pressure air flowing into each duct 10 from step to step decreases. That is, in other words, the primary air flow 24 becomes the largest in the nozzle 3 at the extreme end in the positive direction of the axis S, and the primary air flow 24 becomes gradually smaller toward the nozzle 3 at the extreme end in the negative direction of the axis S.

  Here, as described above, the primary air flow 24 attracts the air outside the induction air passage 21 and the outermost nozzle 3 to generate the secondary air flow 25. The attraction causing the secondary air flow 25 is generated. Since the force is proportional to the size of the primary air flow 24, if a deviation occurs in the size of the primary air flow 24, the largest primary air flow 24 becomes the main flow and attracts the other primary air flow 24. By combining the direction component of the primary air flow 24 which is the main flow with the direction component of the other primary air flow 24, the air blowing range is widened in the + direction of the axis S with respect to the air blowing range u which is an intermediate position. v, and a uniform surface air current spreading in a wide angle in the positive direction of the axis S in the front view of the blower 1 can be obtained.

  FIG. 5C shows the position of the opening adjustment plate 32 in the air blowing range w.

  This is because the flow distribution control unit 34 drives and rotates the adjustment plate motor unit 33 in the negative direction of the axis S to wind up the opening adjustment plate 32, and drives the adjustment plate motor unit 33 in the positive direction of the axis S. Although it is not, it is the state formed by the opening adjustment board 32 which was wound around being pulled out.

  At this time, the opening adjusting plate 32 reduces the opening degree of the inlet 11 of each nozzle 3 from the − direction of the axis S to the + direction in a stepwise manner, so that each inlet 11 from the − direction of the axis S to the + direction. The flow rate of the high-pressure air flowing into each duct 10 from step to step decreases. That is, in other words, the primary air flow 24 becomes the largest at the nozzle 3 at the extreme end in the negative direction of the axis S, and the primary air flow 24 becomes gradually smaller toward the nozzle 3 at the extreme end in the positive direction of the axis S. As a result, the largest primary air flow 24 becomes the main flow, attracts the other primary air flow 24, and the direction component of the other primary air flow 24 is combined with the direction component of the primary air flow 24 that becomes the main flow, so that The blowing range w becomes a blowing range w that widens in the negative direction of the axis S with respect to the blowing range u that is a position, and a uniform surface air current that widens in the negative direction of the axis S in a front view of the blower 1 can be obtained. It can be done.

  As described above, since the blowing range is adjusted by the inflow opening variable damper mechanism 31, the blowing device 1 can adjust the blowing range without moving the housing 2.

Moreover, in the air blower 1 of this Embodiment 1, since the inflow opening variable damper mechanism 31 is stored inside the housing | casing 2, the ventilation range can be adjusted without impairing an external appearance.
(Embodiment 2)
Hereinafter, the configuration of the second embodiment of the present invention will be described in detail only with respect to differences from the first embodiment with reference to FIGS. 6 and 7A to 7C.

6, as shown in FIG. 7C Figures 7A, includes the blower 1 of the second embodiment, the nozzle width variable damper mechanism 36 as a flow amount adjusting section 30 to outlet 12 of the nozzle 3. The variable nozzle width damper mechanism 36 includes opening adjustment plates 37 on both sides of the side surface in the vertical direction of the air outlet 12 of each nozzle 3, and the opening adjustment plate 37 and the adjustment plate motor unit 38 are connected by a shaft 39 extending in the vertical direction. The movement of the adjustment plate motor unit 38 is transmitted to the opening adjustment plate 37, and the adjustment plate motor unit 38 is controlled by the flow rate distribution control unit 34.

  7A to 7C show the position of the opening adjustment plate 37 and the blowing range when adjusting the blowing range.

  In the blower device 1 of the second embodiment, the flow rate distribution control unit 34 drives the adjustment plate motor unit 38 to variably control the angle of the opening adjustment plate 37 connected to the shaft 39, and the blowing range is shown in the figure. Adjustment is made with the range of the air blowing range x, the range of the air blowing range y, and the range of the air blowing range z.

  In the example of the second embodiment, the opening adjusting plate 37a and the opening adjusting plate 37b have a thin plate structure in which one end is connected to the shaft 39a and the shaft 39b provided on the side surface in the vertical direction of the air outlet 12, and the shaft 39a and The angle can be changed in conjunction with the rotation of the shaft 39b. The rotation angles of the shaft 39a and the shaft 39b are adjusted by the adjustment plate motor unit 38a and the adjustment plate motor unit 38b, and the adjustment plate motor unit 38a and the adjustment plate motor unit. 38 b is configured to be controlled by the flow distribution control unit 34.

  7A to 7C show the position of the opening adjustment plate 37 and the blowing range when adjusting the blowing range.

  FIG. 7A shows the position of the opening adjustment plate 37 when the air blowing range x is in the intermediate position. At this time, since the opening areas of the air outlets 12 are equally opened, the primary air flow 24 can be blown out from the plurality of air outlets 12 with almost the same amount of the primary air flow 24. Can be obtained.

  FIG. 7B shows the position of the opening adjustment plate 37a in the air blowing range y.

  This is a state where the flow rate distribution control unit 34 drives the adjustment plate motor unit 38a and the opening adjustment plate 37a connected to the shaft 39a is adjusted in the + direction of the axis S by a predetermined angle.

  At this time, the angle of each opening adjustment plate 37a is adjusted toward the blowing direction of the primary air flow 24 discharged from the nozzle 3 at the extreme end in the + direction of the axis S. That is, the opening adjustment plate 37a at the extreme end in the + direction of the shaft S is not adjusted in angle, and the adjustment angle of the opening adjustment plate 37a in the nozzle 3 is increased stepwise toward the negative direction of the shaft S. The opening width of 12 gradually decreases from the + direction of the axis S toward the − direction, and the flow rate of the primary air flow 24 discharged from each outlet 12 from the + direction of the axis S toward the − direction decreases accordingly. Becomes smaller.

  As a result, the largest primary air flow 24 becomes the main flow, attracts the other primary air flow 24, and the direction component of the other primary air flow 24 is combined with the direction component of the primary air flow 24 that becomes the main flow, so that The air blowing range becomes the air blowing range y that widens in the + direction of the axis S with respect to the air blowing range x that is the position, and a uniform surface air current that widens in the + direction of the axis S in the front view of the air blower 1 can be obtained. It can be done.

  FIG. 7C shows the position of the opening adjustment plate 37 in the air blowing range z.

  This is a state formed by the flow distribution control unit 34 driving the adjustment plate motor unit 38b and the opening adjustment plate 37b connected to the shaft 39b being adjusted by a predetermined angle in the negative direction of the axis S.

  At this time, the angle of each opening adjustment plate 37b is adjusted toward the blowing direction of the primary air flow 24 discharged from the nozzle 3 at the extreme end in the negative direction of the axis S. That is, the angle adjustment angle of the opening adjustment plate 37b in the nozzle 3 increases stepwise toward the + direction of the axis S without adjusting the angle of the opening adjustment plate 37b at the extreme end in the negative direction of the axis S. The opening width of 12 gradually decreases from the − direction of the axis S toward the + direction, and the flow rate of the primary air flow 24 discharged from each outlet 12 from the − direction of the axis S toward the + direction accordingly increases. Becomes smaller.

  As a result, the largest primary air flow 24 becomes the main flow, attracts the other primary air flow 24, and the direction component of the other primary air flow 24 is combined with the direction component of the primary air flow 24 that becomes the main flow, so that The blowing range z becomes a blowing range z that widens in the − direction of the axis S with respect to the blowing range x that is the position, and a uniform surface air current that widens in the − direction of the axis S in a front view of the blowing device 1 can be obtained. It can be done.

  As described above, since the air blowing range is adjusted by the variable nozzle width damper mechanism 36, the air blowing device 1 can adjust the air blowing range without moving the housing 2.

In the blower device 1 according to the second embodiment, the blowing direction of the primary air flow 24 can be adjusted by the adjustment angle of the opening adjustment plate 37, so that the blowing range can be adjusted in a wider range.
(Embodiment 3)
Hereinafter, with respect to the third embodiment of the present invention, the details of the configuration will be described only with respect to the differences from the first and second embodiments with reference to FIG.

  In the blower device 1 according to the third embodiment, in the high-pressure air generator 8, the blower means in which one impeller 5 for generating high-pressure air and one motor 6 for driving the impeller 5 are paired. Two air pressure sensors 41 are provided, and an air blowing control unit 42 that controls the air blowing means 41 is provided.

  Accordingly, when the flow rate distribution control unit 34 and the inflow opening variable damper mechanism 31 or the inflow opening variable damper mechanism 31 and the air blowing control unit 42 are interlocked to adjust the air blowing range in the + direction of the axis S, the shaft Control is performed so that the output of the blowing means 41 in the + direction of S increases and the output of the blowing means 41 in the-direction of the axis S decreases.

  Similarly, when adjusting the blowing range in the negative direction of the axis S, control is performed so that the output of the blowing means 41 in the negative direction of the axis S is increased and the output of the blowing means 41 in the positive direction of the axis S is reduced. To do. As a result, the air blowing range can be adjusted in a wider range.

  Further, by adjusting the output of the air blowing means in accordance with the air volume desired to be obtained, waste of power consumption can be eliminated and the noise can be reduced.

  The air blower and the air purifier with a blower function according to the present invention can provide an air flow with a substantially uniform wind speed over a wide range while eliminating the anxiety caused by the user's contact by including the impeller, and the casing can be moved. Since the air blowing range can be adjusted without causing the air to blow, it is useful as various blower devices that are installed on the floor or wall of a living room and used to reduce the temperature of the body due to direct air flow or to circulate indoor air.
