Description

  The present invention is installed in a room or the outside, and is used to reduce the sensational temperature due to direct air flow or to circulate air in the room, such as a fan such as a fan, and the air taken into the fan. The present invention relates to an air cleaning device with a blowing function, which is used for purifying the air in the room by blowing the air as an air flow, and for reducing the sensible temperature by direct air flow and circulating the air in the room.

  Conventionally, this type of blower includes an impeller and a motor enclosed in a base serving as a pedestal, and air is circulated by blowing air horizontally from the ring-shaped blower provided on the upper portion of the base in the horizontal direction. And the domestic | home-use air blower which produces the flow of air is known (for example, refer patent document 1).

  The blower will be described below with reference to FIGS. 6 and 7.

  FIG. 7 shows a front view showing an example of a conventional fan assembly, and FIG. 8 shows a side sectional view of a portion of the fan assembly of FIG. 7 taken along line X-X '. Blower assembly 100 has an annular nozzle 101 defining a central opening 102. Inside the base 116 of the fan assembly 100 is located a blower that produces an air flow through the annular nozzle 101. In the blower, an impeller (impeller) 130 is connected to a rotating shaft extending outward from a motor 122 disposed with a motor housing 126, and a diffuser 132 is positioned downstream of the impeller 130. The motor 122 is connected to an electrical connection and a power supply (not shown), and the user can operate the fan assembly 100 by a plurality of selection buttons 120 shown in FIG.

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

  When the user selects the preferred button among the plurality of selection buttons 120 shown in FIG. 8 and the motor 122 is activated, air is drawn into the fan assembly 100 through the air inlet 124. Air flows through the outer casing 118 to the inlet 134 of the impeller 130. The air flow leaving the outlet 136 of the diffuser 132 and the exhaust of the impeller 130 is split into two air flows which travel in opposite directions through the internal passage 110.

  The air flow is throttled as it enters port 112 and is further throttled at the outlet 144 of port 112. The throttling causes pressure in the annular nozzle 101.

  The air flow so created overcomes the pressure created by the throttling and exits through outlet 144 as a primary air flow. The primary air flow is directed towards the user in a focused or focused manner by the arrangement of the guide portion 148. The secondary air flow is caused by the suction of air from the external environment, in particular the area around the outlet 144 and the outer edge of the annular nozzle 101. This secondary air flow passes through the central opening 102 where it mixes with the primary air flow to create a total air flow that is expelled forward from the fan assembly 100.

  In such a conventional air blower, since the blowing air path is constant without changing constantly, the blowing range and the wind speed are fixed, and the wind range and the wind speed desired by the user from time to time Had the problem of not being able to

  Then, this invention solves the said conventional subject, and an object of this invention is to provide the air blower which a user can change the range and wind speed of a wind, and an air purification apparatus with a ventilation function.

  And in order to achieve this object, the blower concerning the present invention is provided in the inside of a case, and the case provided with the 1st suction opening and the 2nd suction opening which sucks in air, and generates high-pressure air. A high pressure air generating unit and a plurality of pillars erected from one surface of a housing are provided. The pillar includes a blowout port at a side portion on the front side, which blows high-pressure air generated in the high-pressure air generation unit to the outside of the casing in the direction perpendicular to the direction in which the pillar is erected. A plurality of pillars are provided with a gap so that the outlets are in the same plane, and between the adjacent outlets, an induction air flow region is formed in which the induction air flow generated by being induced by the blowing air flows ing.

  The air blower according to the present invention comprises a housing having a first suction port and a second suction port for sucking air, a high pressure air generation unit provided inside the housing and generating high pressure air, and one surface of the housing A plurality of pillars erected from the side, and the pillars blow out high-pressure air generated in the high-pressure air generating portion in the direction perpendicular to the direction in which the pillars A plurality of pillars are provided with a gap such that the outlets are on the same surface, and an induction air flow generated by being drawn by the outlet air stream between the adjacent outlets. The first suction port is provided at a position regardless of the upstream side of the blowing direction with respect to the blowing port, and the second suction port is upstream of the blowing port in the blowing direction. The first air flow that is provided at the position and sucks air from the first suction port And it is characterized in that it is composed of a control and a second suction port can be switched and a second air flow control for sucking air.

  As a result, the pressure of the induced air flow region of the induced air flow generated by being induced by the blown air flow changes due to the change of the flow rate of the induced air flow accompanying the change of the suction port Has the effect of being able to change the flow of

  First, when the first air flow control is selected, the first suction port is provided at a position regardless of the upstream side in the air blowing direction than the blowout port, so the induction air flow region is a suction air flow flowing to the first suction port Therefore, the difference between the room pressure in the area outside the outermost pillar and the pressure in the induction air flow area is small. For this reason, the blowout air flow blown from each blowout port including the blowout air flow blown from the blowout port of the outermost circumference pillar goes straight on, and the blowout air flow from each blowout port blows in a dispersed state without converging. Ru. On the other hand, when the second air flow control is selected, the second suction port is provided at a position upstream of the blower outlet in the blowing direction, so the induction air flow region is affected by the suction air flow to the second suction port Air pressure in the induced air flow area is lowered. For this reason, a pressure difference occurs between the room pressure in the region outside the outermost pillar and the pressure in the induction air flow region, and the air flow blown out from the outlet of the outermost pillar is an induced air flow with a pressure lower than the room pressure. Deflection to the area side. Each of the inner pillars of the outermost pillars is similarly deflected toward the induction air flow region side of the central region side. As a result, the air flow blown out from the air outlet of each pillar converges on the central region side. Therefore, since the blowoff air flow by the first air flow control does not converge as compared with the air flow by the second air flow control, the air flow range is wide and the air speed is low and uniform. Furthermore, since the blowing airflow converges with the air flow by the second air flow control, the air blowing range is narrow, the air velocity is fast, and the air blowing distance is long, as compared with the air flow by the first air flow control.

  As a result, when the first air flow control is selected, a low wind speed air flow having a wider blowing range is created than when the second air flow control is selected, so a large number of users can obtain a cool feeling. become. On the other hand, when the second air flow control is selected, since a high wind speed air flow having a narrower air flow range is created than when the first air flow control is selected, a small number of users get a strong feeling of coolness. And increase the efficiency of air circulation.

  In addition, the control unit of the blower has a third air flow control that sucks air from both the first suction port and the second suction port.

  Thereby, it is possible to select the third air flow control whose air pressure in the induction air flow region is lower than the first air flow control and higher than the second air flow control.

  As a result, it is possible to create the third air flow control air flow that is faster than the first air flow control and has a wider air flow range than the second air flow control.

  Further, the blower device is characterized in that switching of the intake air from each suction port is performed by a shield plate. This makes it possible to select the first air flow control and the second air flow control with a simple flat plate. As a result, by suppressing the number of parts, it is possible to reduce the number of assembly steps and the cost.

  Further, the air blower is characterized in that a shielding plate is provided inside the housing. As a result, it is possible to select the first air flow control and the second air flow control without the need to operate the parts constituting the appearance of the air blower. As a result, it is possible to maintain the high design of the blower and have the second air flow control and the first air flow control.

  In addition, the air blower is characterized in that a shielding plate is provided outside the housing. Thus, by operating the shielding plate having visibility, it is possible to select the first air flow control and the second air flow control. As a result, the user can recognize the setting state of the air blowing mode from the appearance of the air blowing device.

  In addition, the air purification apparatus with air flow function is an air purification apparatus with air flow function characterized by including an air purification filter in the first suction port or the second air suction port of the air blower. Thus, the air taken in from the suction port is purified by the air purification filter and blown out from the air outlet, so that the purified air can be provided to the user.

Is removed, that is, the first suction port 3 is closed and the second suction port 4 is opened, which is the second air flow control state.

  Further, as shown in FIG. 3, in the case of the first air flow control, the second shielding plate 11 closing the second suction port 4 is inserted into the inside of the blower 1, and in the case of the second air flow control, The first shielding plate 12 closing the first suction port 3 is inserted into the inside of the blower 1.

Each is formed. The first shielding plate insertion port 13 is provided on the front surface provided with the blowout port 8 of the housing 2 at a position covering the first suction port 3, and the first shielding plate insertion port 13 is By the shielding plate 12 being inserted, as shown in FIG.1 (b) and FIG.3 (b), the 1st suction inlet 3 is obstruct | occluded. Further, the second shielding plate insertion port 14 is provided at a position covering the second suction port 4, and the second shielding plate 11 is inserted into the second shielding plate insertion port 14 as shown in FIG.

  Although the width of the first shielding plate 12 is 206 mm and the width of the second shielding plate 11 is 105 mm, the width of the first shielding plate 12 and the width of the second shielding plate 11 are the same. It is also good. Thereby, it is possible to use one plate as the first shielding plate 12 and the second shielding plate 11. By suppressing the number of parts, it is possible to reduce the cost.

  FIG. 4 shows a cross-sectional view showing the internal shape of the air blower 1 in the cross section AA 'in FIG. 2 and a schematic view of the air flow. 4A shows the state of the first air flow control of the air blower 1, and FIG. 4B shows the state of the second air flow control of the air blower 1.

  As shown in FIG. 4, the inside of the pillar 6 is provided with a duct 16 for guiding high pressure air to the outlet 8. The ducts 16 are provided in the same number as the pillars 6. A chamber space 17 is provided between the high pressure air generating unit 5 and the plurality of ducts 16 for dividing the high pressure air into the respective pillars 6.

  According to such a configuration, as shown in FIG. 4, the motor (not shown) constituting the high-pressure air generation unit 5 is driven, and as the impeller 23 rotates, as shown in the internal flow 18, The indoor air is taken in from the first suction port 3 or the second suction port 4 into the inside of the blower 1 (the housing 2) as a suction air flow 19, passes through the impeller 23, and reaches the chamber space 17. The high pressure air formed by passing the impeller 23 is divided into six ducts 16 in the chamber space 17, passes through the respective ducts 16, and the air direction adjusting rib 20 provided in the vicinity of the air outlet 8 The air blown in the vertical direction 6 is deflected and blown out from the blowout port 8 to form a blowout air flow 21.

  As shown in FIG. 4A, in the state of the first air flow control, the suction air flow 19 is taken in from the front surface of the housing 2. On the other hand, as shown in FIG. 4 (b), in the second air flow control state, the suction air flow 19 is taken in from the upper surface on the rear side of the housing 2.

  FIG. 5 shows a cross-sectional view showing the internal shape of the air blower 1 in the B-B ′ cross-section in FIG. 2 and a schematic view of the flow. Although the cross-sectional shape of the pillar 6 is a rectangular shape as shown in FIG. 5, it may be a shape extending in the blowing direction, and may be another shape such as an ellipse.

  Due to the nature of the viscosity of air, another air flow is generated by attracting the stationary air around the air flow to the air flow flowing with a constant wind speed. Also in this configuration, another air flow is generated as a result of being drawn by the blow-off air blown out from the blowout port, and these two types of air flows are combined and blown.

  In the first embodiment, as shown in FIG. 5, the air in the adjacent induction air flow area 10 (in the outermost pillar 6, the adjacent induction is induced by being drawn by the blowout air flow 21 blown out from the outlet 8. The air in the air flow area 10 and the air outside the outermost pillars 6 are attracted, and the induced air flow 22 (the inducement air flow outside the outermost pillars 6 is not shown) is generated by the blown air flow 21. The blowout air flow 21 and the induction air flow 22 join at the downstream of the blowout port 8 of the air blower 1, and it becomes possible to create a substantially uniform air flow over a wide area.

  Although the details will be described later, at this time, the pressure of the induction air flow area 10 by the position of the intake air for taking in the indoor air into the inside of the blower 1 (the housing 2) by either the first suction port 3 or the second suction port 4 Changes. The flow of the blown air 21 changes due to the influence of the pressure of the induced air flow area 10. As a result, the wind direction of the combined airstream in which the blowout air stream 21 and the induction air stream 22 merge is changed.

  The flow of each air flow in each case of the first air flow control and the second air flow control of the blower 1 will be described below.

  In FIG. 6, sectional drawing which shows the internal shape of the air blower 1 in the AA 'cross section in FIG. 2, and the schematic diagram of air flow are shown.

  When the first air flow control is selected, air is taken into the inside of the housing 2 from the first suction port 3. The first suction port 3 is provided on the front surface of the housing 2, and the position of the first suction port 3 is a position not related to the upstream side of the blowing port 8 in the blowing direction. The position not related to the upstream side in the blowing direction from the blowout port 8 is to be located downstream of the blowout port 8 in the blowout air flow 21 and the induced air flow 22. In this case, as shown in FIGS. 5 (a) and 6 (a), the induction air flow area 10 is not affected by the suction air flow 19 flowing to the first suction port 3, and hence the area outside the outermost pillar 6 The difference between the room air pressure and the air pressure in the induction air flow area 10 is small. Therefore, as shown in FIG. 5 (a), the blown air 21 blown from each blow outlet 8 including the blown air blown from the blow outlet 8 of the outermost pillar 6 goes straight on, and The blowout air flow 21 from the blowout port 8 is blown in a dispersed state without convergence.

  On the other hand, when the second air flow control is selected, air is taken into the inside of the housing 2 from the second suction port 4. The second suction port 4 is provided on the upper surface on the rear side of the housing 2, and the position of the second suction port 4 is a position on the upstream side of the blowout port 8 in the blowing direction. In this case, as shown in FIG. 5B and FIG. 6B, the induced air flow area 10 is affected by the suctioned air flow 19 flowing to the second suction port 4, so the air pressure in the induced air flow area 10 becomes low. Therefore, a pressure difference occurs between the room pressure in the region outside the outermost pillar 6 and the pressure in the induction air flow region 10, and the air flow 21 from the outlet 8 of the outermost pillar 6 is higher than the room pressure. It is deflected toward the low air pressure induction air flow area 10 side. Similarly, the respective pillars 6 on the inner side of the outermost pillars 6 are also deflected toward the induction air flow region side of the central region side. As a result, the air flow blown out from the blowout port of each pillar 6 converges to the central region side.

  Therefore, since the blowing air flow by 1st air flow control does not converge each blowing air flow 21 compared with the air blowing by 2nd air flow control, the air blowing range is wide and the wind speed becomes slow and uniform. Furthermore, since the blowoff air flow according to the second air flow control converges the respective blowout air flows 21 rather than the air flow according to the first air flow control, the air blowing range is narrow, the wind speed is fast, and the air blowing distance is long.

  As a result, when the first air flow control is selected, a low wind speed air flow having a wider blowing range is created than when the second air flow control is selected, so a large number of users can obtain a cool feeling. become. On the other hand, when the second air flow control is selected, since a high wind speed air flow having a narrower air flow range is created than when the first air flow control is selected, a small number of users get a strong feeling of coolness. And increase the efficiency of air circulation.

  In the blower device 1 of the first embodiment, the state of the first air flow control and the state of the second air flow control can be easily switched simply by changing the intake position of the air into the housing 2. is there. Further, the user of the blower 1 can appropriately change the range of the wind and the wind speed.

  The present disclosure has been described above based on the embodiments. It is understood by those skilled in the art that these embodiments are exemplifications, and that various modifications can be made to the combinations of the respective components and processing processes, and such modifications are also within the scope of the present disclosure. It is a place.

  In the first embodiment, the high-pressure air generating unit 5 is contained in the housing 2 so that the user can not contact from the outside, which makes it possible to eliminate anxiety due to the contact. The high pressure air generating unit 5 may be installed outside the housing 2.

  Further, in the first embodiment, as shown in FIG. 4, a wind direction adjusting rib 20 for deflecting the wind along the rising direction of the pillar 6 is provided in the vicinity of the outlet 8 in the pillar 6. As a result, the high-pressure air delivered from the high-pressure air generator 5 is deflected from the rising direction of the pillar 6 and blown from the outlet 8. However, the wind direction adjusting rib 20 may not be provided.

  Further, in the first embodiment, the user can manually detach and attach each of the first shielding plate 12 and the second shielding plate 11 to the inside of the air blower 1. As a result, since the structure and remote control of the complicated air blower 1 for operating the first shielding plate 12 and the second shielding plate 11 in the air blower 1 are not required, it is possible to reduce the assembly man-hour and cost. Become. Furthermore, since components of the blower device 1 having visibility are not operated, the second airflow control and the first airflow control can be provided while maintaining the appearance of the blower 1.

  However, by adopting a mechanism in which the first shielding plate 12 and the second shielding plate 11 are operated by a stepping motor or the like, the user automatically uses a remote controller to operate the stepping motor or the like. You may make it removable. This makes it possible to appropriately change the range of wind and the speed of wind, without requiring labor and time for the user.

  Moreover, in this Embodiment 1, although the place which takes in indoor air in the air blower 1 inside was either the 1st suction port 3 or the 2nd suction port 4, it was clearly stated that the 1st suction port 3 and the 2nd Both suction ports 4 may be used as suction ports. As a result, the third air flow control in which the pressure in the induction air flow region 10 is lower than the first air flow control and higher than the second air flow control is selected. As a result, it is possible to have third air flow control in which the wind speed is higher than the first air flow control and the air receiving range is larger than the second air flow control, and the wind range and the wind speed can be changed more appropriately.

  Further, in the first embodiment, all of the pillars 6 are provided in parallel with the blowing direction, but there is no particular limitation on the direction and the number of the pillars 6. However, it may be provided in a wide angle such that the air blow-off direction is away from the pillar 6 at the central portion toward the pillar 6 provided outside from the center of the housing 2. As a result, it is possible to suppress the phenomenon in which the air flow gathers in the central portion of the blower 1 up to a fixed distance from the blower 1 and to widen the range of the wind. However, since the degree of strength of this phenomenon largely depends on the width of the gap 9 sandwiched by the pillars 6, a significant effect can not be expected.

  In the first embodiment, the number of the pillars 6 is six, the width of the blower 6 is 620 mm, the width of the pillars 6 is 45 mm, and the length of the gap 9 is 100 mm. There is no. However, the user can appropriately change the width of the blower 1, the number of the pillars 6, and the like according to the space and the design.

  In the first embodiment, at least one of the first suction port 3 and the second suction port 4 of the blower 1 may be provided with a purification filter. Thereby, by cleaning the air taken in from each suction port with a filter, it is possible to suppress the adhesion of dirt to the high-pressure air generation unit 5, and it is possible to provide the air blower 1 in which the air blowing performance is unlikely to deteriorate.

  In the first embodiment, an air purification filter may be provided to at least one of the first suction port 3 and the second suction port 4 of the blower 1. This makes it possible to blow the purified air, and the blower 1 can be provided as an air cleaner with a blower function.

  The air blower according to the present invention and the air purification device with air blower function are useful as the air blower capable of appropriately changing the range of wind and the wind speed of the user.
