Description

TECHNICAL FIELD The present invention relates to an air blower that blows air imparted with characteristics beneficial to the user to a desired area while suppressing the attraction of outside air.

Conventionally, as this type of blower, an impeller and a motor are included in a base serving as a pedestal, and the air is circulated by blowing out in a horizontal direction to the floor from an annular blowing part provided at the top of the base. and an electric fan that generates an air flow (see, for example, Patent Document 1).

A conventional blower cleans the air taken in from the atmosphere around the blower by passing it through a built-in filter, and then blows it out again from the blowout part into the surrounding atmosphere as a blowing airflow. At this time, the induced airflow is generated by efficiently inducing the surrounding atmosphere with the blown airflow. As a result, the blown air current and the induced air current are combined to discharge a large amount of air current in front of the blower.

JP 2010-077969 A

In such a conventional air blower, the induced airflow that joins the blown-out airflow from which fine particles have been removed from the atmosphere by passing through a filter is formed by the ambient air containing fine particles. . This is because, due to the viscous properties of air, the fluid is attracted by the blowing airflow blown out from the blowing part, and the ambient air, which contains fine particles around the blowing airflow and is stationary, joins the blowing airflow. This is because it will flow as the formed air-fuel mixture flow. As a result, even if the airflow from which the fine particles have been removed is blown toward an area a desired distance away from the blower, the mixed airflow in that area contains a large amount of fine particles.

In other words, even if a blowing airflow imparted with characteristics that are highly clean and beneficial to the user is generated, the outside air that is less clean and beneficial or harmful to the user may be attracted, and the desired air having that characteristic is generated. However, there is a problem that it is not possible to form an area separated by a distance of .

Therefore, the present invention is intended to solve the above-described conventional problems, and provides a blower capable of blowing air imparted with characteristics beneficial to the user to a desired area while suppressing the attraction of outside air. intended to provide

In order to achieve this object, the blower according to the present invention includes an air inlet for taking air into a housing, a high-pressure air generating section for converting the air sucked from the air inlet into high pressure air, and a a uniqueness imparting part that imparts uniqueness to air or high-pressure air; a plurality of hollow pillars that are arranged side by side with a predetermined gap on one surface of the housing and protrude and extend in a direction away from the one surface; a blowout port provided on the side surfaces of the hollow pillars facing each other for blowing high-pressure air toward the side surfaces of the adjacent hollow pillars. Between the hollow column and the adjacent hollow column, the gap defines an air passage having a first opening and a second opening facing the first opening. The high-pressure air blown out from the air outlet flows through the air passage and is discharged from the first opening and the second opening. This achieves the intended purpose.

ADVANTAGE OF THE INVENTION According to this invention, the air blower which can ventilate the air given the characteristic useful for a user to a desired area can be provided, suppressing the attraction of outside air.

Between the hollow column and the adjacent hollow column, the gap defines an air passage having a first opening and a second opening facing the first opening. The high-pressure air blown out from the blow-out port flows through the air passage and is discharged from each of the first opening and the second opening.

According to such a configuration, the high-pressure air imparted with uniqueness by the uniqueness imparting section is blown out from the first opening and the second opening configured by the plurality of hollow pillars. At this time, the high-pressure air discharged from the first opening and the second opening are discharged adjacent to each other with the hollow column interposed therebetween. The amount of inflow is suppressed. In other words, the blower can blow the air imparted with characteristics that are beneficial to the user to the desired area while suppressing the attraction of outside air.

Further, in the blower device according to the present invention, the outlet includes a first outlet provided on the side surface of the hollow pillar and a second outlet provided on the side surface of the opposing hollow pillar. The high-pressure air blown out from and the high-pressure air blown out from the second outlet collide with each other and are discharged from the first opening and the second opening.

As a result, even in a situation where disturbance wind containing outside air that tries to flow from the first opening to the second opening or from the second opening to the first opening occurs, the high-pressure air that flows toward the first opening is the disturbance wind that tries to flow from the first opening toward the second opening, the high-pressure air that flows toward the second opening is the disturbance that tries to flow from the second opening toward the first opening It becomes a headwind against the wind, and it is possible to suppress the inflow of disturbance wind, that is, the attraction of outside air.

In addition, in the blower device according to the present invention, the first blowing direction of the high-pressure air blown from the first blowing port and the second blowing direction of the high-pressure air blown from the second blowing port are both the same first direction. It is biased toward the opening side or the same second opening side. This makes it possible to form a strong headwind against the direction in which the stronger disturbance wind flows, and suppress the inflow of the disturbance wind, that is, the attraction of the outside air. For example, when a disturbance wind that flows from the first opening toward the second opening occurs, both the first blowing direction and the second blowing direction are set to the same first opening side, so that the first blowout port It is possible to further increase the total component of the first blowing direction component of the high pressure air blown out from the second outlet and the first blowing direction component of the high pressure air blown out from the second outlet.

The control unit controls the first blowing direction and the second blowing direction to control a first flow rate of high-pressure air discharged from the first opening and a second flow rate of high-pressure air discharged from the second opening. adjust. As a result, the relative relationship between the wind speed in the area to which the first opening is directed and the wind speed in the area to which the second opening is directed can be appropriately adjusted during operation of the blower according to the intended use.

Moreover, the air blower according to the present invention further includes a pressure loss section in at least one of the first opening and the second opening. The pressure loss portion adjusts a first flow rate of high-pressure air discharged from the first opening and a second flow rate of high-pressure air discharged from the second opening. This makes it possible to adjust the relative relationship between the wind speed in the area to which the first opening is directed and the wind speed in the area to which the second opening is directed before operating the blower according to the intended use.

Further, in the blower device according to the present invention, it is preferable that the end portions of the plurality of hollow columns forming at least one of the first opening and the second opening are chamfered. By doing so, the high-pressure air discharged from the first opening or the high-pressure air discharged from the second opening can easily flow along the outer wall surface of the hollow column. As a result, the energy loss due to the vortex region of the high-pressure air discharged from the first opening formed at the end of the hollow column or the high-pressure air discharged from the second opening is suppressed, and the energy saving performance of the blower is improved. can be enhanced.

In addition, the blower device according to the present invention further includes a third outlet for blowing out high-pressure air on another side surface of the hollow column that is the same side as the first opening or the second opening, and the high-pressure air is provided from the outlet. , a second state in which high-pressure air is blown out from the third outlet, and a third state in which high-pressure air is blown from the outlet and the third outlet.

At this time, the air path switching plate 26 is used to blow out the purified air-conditioned high-pressure air from the outlets 20 (the first outlet 20a, the second outlet 20b) in the first mode, and the third outlet 22 to outlet the purified air-conditioned high-pressure air. The mode is switched between the second mode and the third mode in which purified air-conditioned high-pressure air is blown out from the outlets 20 (the first outlet 20a, the second outlet 20b) and the third outlet 22. FIG.

<First mode>
The first mode, as shown in FIG. 10, is a mode in which the first communication port 27 and the first internal air passage 23 are connected for communication by moving the air passage switching plate 26 . In the first mode, the air blower 1 blows out high-pressure air (purified air-conditioning high-pressure air) from the outlets 20 (first outlet 20a, second outlet 20b) of the central column 17 shown in FIG. state (first state).

In the first state, as shown in FIG. 11, the first blower outlet 20a blows out the first airflow 33a in the external air passage 32 toward the adjacently facing second blower outlet 20b side. On the other hand, the second outlet 20b blows out a second airflow 33b in the external air passage 32 toward the side of the adjacently facing first outlet 20a. At this time, the first outlet 20a faces the second outlet 20b formed in another adjacent central pillar 17, and the second outlet 20b faces the second outlet 20b formed in another adjacent central pillar 17. The first airflow 33a and the second airflow 33b collide with each other because they face the one outlet 20a. In addition, since the first air outlet 20a and the second air outlet 20b are formed by the punching plate 21 (see FIG. 5) having the same size and shape, the first airflow 33a and the second airflow 33b are the same. and collide with each other at a flow rate of As a result, the respective airflows after the collision of the two airflows are deflected at a substantially right angle and flow through the external air passages 32 formed by the gaps between the adjacent central pillars 17 to the first area 4 side and the first area 4 side. It is blown out to both of the second area 5 sides. In other words, the air blower 1 generates airflow in two opposite directions on the first area 4 side and the second area 5 side.

The external air passage 32 includes one central pillar 17 at each of eight central pillars 17 (one left central pillar 18a, one right central pillar 18b, six non-outer central pillars 19), It is an air passage formed by a gap (a gap between two central pillars 17) with the central pillar 17 adjacent thereto, and includes a first opening 34a facing the first area 4 and a first opening 34a facing the second area 5. and a second opening 34b. That is, the first opening 34a and the second opening 34b are formed facing each other. The lower end of the gap between the two central pillars 17 is closed by the housing 6, and the upper end of the gap between the two central pillars 17 is closed by the top plate 8 (see FIG. 4).

The first opening 34a is an opening on the side of the external air passage 32 facing the first area 4, and allows one of the two directions of airflow generated by the collision of the first airflow 33a and the second airflow 33b. It blows out as a first mixture stream 35 .

The second opening 34b is an opening on the side facing the second area 5 in the external air passage 32, and allows the other airflow of the two directions of airflow generated by the collision of the first airflow 33a and the second airflow 33b. It blows out as a second mixture stream 36 .

More specifically, the air blower 1 has seven external air passages 32 formed by eight central pillars 17 . Then, the blower 1 blows out the first mixed gas flow 35 and the second mixed gas flow 36 from the first openings 34a and the second openings 34b formed in each of the seven external air passages 32, respectively.

Each of the first mixture flows 35 is blown out from the first openings 34a in a direction (direction along the central axis 11 in FIG. 2) orthogonal to the direction in which the central pillar 17 (the plurality of pillars 7) is erected. be done. Then, the first mixed airflow 35 blown out from the first opening 34 a flows toward the first area 4 as a first surface airflow 37 that is combined with the first airflow 35 . Here, the first surface airflow 37 flows toward the first area 4 over a vast area surrounded by the housing 6, the top plate 8, the left end central pillar 18a, and the right end central pillar 18b shown in FIG.

Each of the second mixed gas flows 36 is blown out from the second openings 34b in the direction opposite to the first mixed gas flow 35 . Then, the second mixed airflow 36 blown out from the second opening 34b flows toward the second area 5 as a second surface airflow 38 in which they are combined. Here, the second surface airflow 38 flows toward the second area 5 over a vast area surrounded by the housing 6, the top plate 8, the left end center pillar 18a, and the right end center pillar 18b shown in FIG.

At this time, as a general phenomenon, due to the viscous property of the fluid of air, any air current will flow together with the induced air current in which the still air in contact with the air current is attracted.

Since the first mixed gas flow 35 is blown out adjacently across the non-outer end central column 19 , there is space between the adjacent first mixed gas flows 35 , that is, the lateral side of the non-outer end central column 19 . In the surrounding space, the induced airflow 39a induced by the first mixed airflow 35 flows together from the upper side (the top plate 8 side) and the lower side (the housing 6 side) of the air blower 1 . The induced airflow 39 a is formed of air (indoor air 31 ) corresponding to still air in contact with the first mixed airflow 35 .

However, the short width (40 mm) of one non-outer end central pillar 19 with respect to the total width (2020 mm) of the blower 1 or the distance (1580 mm) between the left end central pillar 18a and the right end central pillar 18b is Since it is very small, the flow rate of the induced airflow 39a is small and its influence is small.

Further, when the first surface airflow 37 in which the first mixed airflow 35 is combined flows, an induced phenomenon occurs at the outer periphery of the first surface airflow 37 (the first mixed airflow 35 at both outer ends), and the induced airflow 39b is generated. They will flow together. However, the first surface airflow 37 and the indoor air 31 are in contact only at the outer circumference of the first surface airflow 37, and the induced airflow 39b joins only from the outer circumference of the first surface airflow 37. In other words, users of the desks 2 and chairs 3 in the first area 4 positioned in the central portion 40a of the first surface airflow 37 are less likely to be exposed to the induced airflow 39b mixed with the indoor air 31.

Since the first airflow 33a and the second airflow 33b, which are the sources of the first surface airflow 37, are purified, air-conditioned, high-pressure air, even if the temperature of the indoor air 31 is harmful and uncomfortable to the human body, A user of the first area 4 located in the part 40a can enjoy harmless and comfortable air.

The second mixed gas flow 36 is similar to the first mixed gas flow 35 . Since the second air-fuel mixture flow 36 is blown out adjacently across the non-outer end central pillar 19, the space between the adjacent second air-fuel mixture flows 36, that is, the space around the lateral side of the non-outer end central pillar 19 , the induced airflow 39a induced by the second mixed airflow 36 flows together from the upper side (the top plate 8 side) and the lower side (the housing 6 side) of the blower device 1 . The induced airflow 39 a is formed of air (indoor air 31 ) corresponding to still air in contact with the second mixed airflow 36 .

However, as described above, the flow rate of the induced airflow 39a is small, so the effect is small.

Further, when the second surface airflow 38 in which the second air mixture flow 36 is combined flows, an induction phenomenon occurs on the outer circumference of the second surface airflow 38 (the second airflow mixture 36 at both outer ends), and the induction airflow 39b is generated. They will flow together. However, the second surface airflow 38 and the indoor air 31 are in contact only at the outer periphery of the second surface airflow 38 , and the induced airflow 39 b joins only from the outer periphery of the second surface airflow 38 . In other words, users of the desks 2 and chairs 3 in the second area 5 located in the central portion 40b of the second surface airflow 38 are less likely to be exposed to the induced airflow 39b mixed with the indoor air 31.

The first airflow 33a and the second airflow 33b, which are the sources of the second surface airflow 38, are the same purified air-conditioning high-pressure air as the first surface airflow 37. Even with the temperature, users of the second area 5 located in the central part 40b can enjoy harmless and comfortable air.

As described above, in the blower device 1, even in the presence of the indoor air 31 that is useless or harmful to the user, the attraction of the indoor air 31 is suppressed, and the unique air that is beneficial to the user ( Purified and conditioned air) can be blown to the desired area.

<Second mode>
The second mode, as shown in FIG. 12, is a mode in which the second communication port 28 and the second internal air passage 24 are connected for communication by moving the air passage switching plate 26 . In the second mode, the blower device 1 is in a state (second state) in which high-pressure air (purified air-conditioning high-pressure air) is blown out from each of the third outlets 22 of the central column 17 shown in FIG.

In the second state, as shown in FIG. 13, the third outlet 22 blows out the third airflow 33c toward the first area 4 and the second area 5, respectively. In other words, the air blower 1 generates airflow in two opposite directions on the first area 4 side and the second area 5 side.

More specifically, the third outlets 22 are provided in each of the eight central pillars 17 (one left central pillar 18a, one right central pillar 18b, six non-outer central pillars 19). The third airflow 33c is blown out in both directions of the one area 4 side and the second area 5 side. At this time, unlike the first mode, there is no loss of energy due to collision between the third air currents 33c. Therefore, compared to the first mode, the power consumption of the high-pressure air generator 15 (see FIG. 9) can be reduced when airflow having a desired wind speed is conveyed to the first area 4 and the second area 5. It becomes possible and the energy saving property of the air blower 1 can be improved.

On the other hand, in the second mode, in the space sandwiched by the third airflow 33c toward each area, that is, the space around the interval (180 mm) between the adjacent central pillars 17, above the blower 1 (top plate 8 side) and An induced airflow 39c is generated from below (from the housing 6 side) by being attracted by the third airflow 33c.

As a result, a surface airflow (first surface airflow 37a, second surface airflow 38a) in which the third airflow 33c and the induced airflow 39c are mixed is generated. Since it is wider than the space (40 mm) into which the induced airflow 39a in one mode flows, the flow rate of the induced airflow 39c increases.

That is, in the second mode, compared with the first mode, the user in the first area 4 located in the central portion 40a of the first surface airflow 37a or the user located in the central portion 40b of the second surface airflow 38a A user of the second area 5 who is in the room is likely to be exposed to the induced airflow 39c mixed with the indoor air 31.例文帳に追加For this reason, the second mode is, for example, after the air blower 1 has been operated in the first mode for a certain period of time, and after the indoor air 31 has been cleaned and air-conditioned to a temperature that is harmless to the human body and not significantly uncomfortable. Use is highly recommended.

<Third mode>
In the third mode, as shown in FIG. 14, by moving the air passage switching plate 26, the third communication port portion 29 and the first internal air passage 23 are connected for communication, and the third communication port portion 29 and This is a mode for communicating with the second internal air passage 24 . In the third mode, the blower device 1 outputs high-pressure air (purified Air conditioning high pressure air) is blown out (third state). That is, in the third state, both the first state by the first mode and the second state by the second mode are generated.

Specifically, in the third state, the configuration of the first mode shown in FIG. be done. Further, in the third state, the third airflow 33c is blown out toward each of the first area 4 and the second area 5 due to the configuration of the second mode shown in FIG.

Then, the first mixed airflow 35 and the third airflow 33c flow toward the first area 4 as a first surface airflow 37b in which they are combined. Further, the second mixed airflow 36 and the third airflow 33c flow toward the second area 5 as a second surface airflow 38b in which they are combined.

As described above, in the third mode, the behavior of the airflow is a combination of the first mode and the second mode. The user of 40b) can enjoy harmless and comfortable air, and the energy saving performance of the blower 1 can be improved.

Next, with reference to FIG. 16, the chamfering process applied to the rectangular square of the central column 17 will be described. FIG. 16 is a schematic diagram showing the flow of airflow in the vicinity of the central column 17 that constitutes the blower device 1 according to Embodiment 1. As shown in FIG. Here, (a) of FIG. 16 shows a state in which the rectangular square of the central pillar 17 is not chamfered (a rectangular state), and (b) of FIG. 16 shows the central pillar 17. It shows a state in which chamfering has been performed on the rectangular square of .

As shown in FIG. 16(a), when the central column 17 is left rectangular, the first mixed gas flow 35 and the second mixed gas flow 36 are generated in the vicinity of the corner ends 46a of the central column 17. The directionality of the airflow is disturbed by the swirling vortex regions 47, resulting in unwanted energy dissipation for each air-fuel mixture flow. In addition, since the space around both lateral sides of the central column 17 in the first mode is expanded by the vortex region 47, the air blower 1 is above (top plate 8 side) and below (housing 6 side) This will lead to an increase in the flow rate of the induced airflow 39a (see FIG. 11) flowing from.

On the other hand, as shown in (b) of FIG. Since it flows along the portion 46, not only is the above-described vortex region 47 less likely to occur, but the space around both lateral sides of the central column 17 in the first mode becomes narrower. As a result, the induced airflow 39a (see FIG. 11) flowing into this space from above (the top plate 8 side) and below (the housing 6 side) of the blower device 1 can be suppressed.

<Comparative Example 1>
A blower device 101 according to Comparative Example 1 will be described with reference to FIG. 17 . FIG. 17 is a schematic diagram of a blower device 101 according to Comparative Example 1. FIG. Here, (a) of FIG. 17 is a perspective view of the blower 101, and (b) of FIG. 17 is a vertical sectional view of the blower 101. As shown in FIG.

In the blower device 101 according to Comparative Example 1, as shown in (a) of FIG. 17, the outlets for blowing out to the first area 4 and the second area 5 were formed by a punching plate provided with numerous opening holes. It is different from the first embodiment in that it has one front air outlet 102 . Other basic configurations are the same as those of the blower device 1 according to the first embodiment.

A blower device 101 according to Comparative Example 1, as shown in FIG.

The third chamber 103 is provided with a full-surface outlet 102 on a side surface facing each of the first area 4 and the second area 5 . Then, as indicated by the internal flow 104 indicated by the dashed arrow, the high-pressure air (purified air-conditioning high-pressure air) sent from the second chamber 14 to the third chamber 103 becomes a blown air flow 105 from the front outlet 102, and flows into the first chamber. It blows out to each of the area 4 and the second area 5 .

In the blower device 101 according to Comparative Example 1, the principle of the internal flow 104 is almost the same as that of the blower device 1, but the front outlet 102 directs the flow from the second area 5 side to the first area 4 side (or the first area 4 side). (2nd area 5 side) cannot be visually recognized, so a feeling of openness as a partition cannot be given.

<Comparative Example 2>
A blower device 201 according to Comparative Example 2 will be described with reference to FIG. 18 . FIG. 18 is a schematic diagram of a blower device 201 according to Comparative Example 2. As shown in FIG.

A blower device 201 according to Comparative Example 2 differs from Embodiment 1 in that the second opening 34b facing the second area 5 is closed by a flat plate 202, as shown in FIG. Other basic configurations are the same as those of the blower device 1 according to the first embodiment.

The flat plate 202 is a member that closes the second opening 34 b facing the second area 5 . The flat plate 202 has a vast area surrounded by the housing 6, the top plate 8, the left end central pillar 18a, and the right end central pillar 18b shown in FIG. In Comparative Example 2, the second opening 34b facing the second area 5 is closed, but the first opening 34a facing the first area 4 on the opposite side may be closed.

The air blower 201 according to Comparative Example 2 blows the first mixed airflow 35 (and thus the first surface airflow 37) only to the first area 4 in the first mode. That is, since the second opening 34 b of the blower device 201 is closed by the flat plate 202 , nothing is blown to the second area 5 .

In the blower device 201 according to Comparative Example 2, the first airflow 33a and the second airflow 33b, which are the sources of the first surface airflow 37, are purified air-conditioned high-pressure air. The user of the first area 4 located in the central part 40a can enjoy harmless and comfortable air even at a temperature of about 100.degree. However, since the flat plate 202 does not make it possible to see from the first area 4 side to the second area 5 side (or from the second area 5 side to the first area 4 side), it is not possible to give a sense of openness as a partition.

As described above, according to the blower device 1 according to the first embodiment, the following effects can be obtained.

(1) The blower device 1 includes a suction port 9 that takes in air (indoor air 31) into the housing 6, a high-pressure air generator 15 that converts the air sucked from the suction port 9 into high-pressure air, and a suction port 9. An air purifying filter 10 for purifying air, a plurality of central pillars 17 arranged side by side with a predetermined gap on one surface of a housing 6 and projecting and extending in a direction away from the one surface, and a plurality of central pillars 17. Blow-out ports 20 (first blow-out port 20a, second blow-out port 20b) are provided on side surfaces facing each other and blow high-pressure air toward the side surfaces of the adjacent central columns 17 . Between the central post 17 and the adjacent central post 17, the gap defines an external air passage 32 having a first opening 34a and a second opening 34b facing the first opening 34a. The high-pressure air blown out from the outlet 20 flows through the external air passage 32 and is discharged from the first opening 34a and the second opening 34b.

According to such a configuration, the high-pressure air purified by the air purification filter 10 is blown out from the first opening 34a and the second opening 34b formed by the plurality of central columns 17, respectively. At this time, the high-pressure air discharged from the first opening 34a and the second opening 34b are discharged adjacent to each other with the central column 17 interposed therebetween. The amount of inflow of outside air (induction airflow 39a) is suppressed. In other words, the blower 1 can blow the air to the desired areas (the first area 4 and the second area 5) with air purification that is unique and beneficial to the user while suppressing the attraction of outside air. can be done.

(2) In the blower device 1, the outlets 20 include a first outlet 20a provided on the side surface of the central pillar 17 and a second outlet 20b provided on the side surface of the opposing central pillar 17. The high-pressure air (first airflow 33a) blown out from the first blow-out port 20a and the high-pressure air (second airflow 33b) blown out from the second blow-out port 20b collide with each other to form the first opening 34a and the second opening 34b. from each of the As a result, the high-pressure air (the first air-fuel mixture flow 35 and the second air-fuel mixture flow 36) blown out from the air outlets 20 (the first air outlet 20a and the second air outlet 20b) collides with each other in the gaps between the adjacent central columns 17. It becomes an airflow having a blowing area corresponding to the cross-sectional area. As a result, even in a situation where external disturbance wind including external air that tries to flow from the first opening 34a to the second opening 34b or from the second opening 34b toward the first opening 34a is generated, the first opening 34a The high-pressure air (first mixture flow 35) flowing toward the second opening 34b resists the disturbance wind that is about to flow from the first opening 34a toward the second opening 34b. The mixture flow 36) acts as a counterwind to the disturbance wind that is about to flow from the second opening 34b toward the first opening 34a, and can suppress the inflow of the disturbance wind, that is, the attraction of outside air.

(3) In the blower 1, the ends (rectangular squares) of the plurality of central columns 17 forming at least one of the first opening 34a and the second opening 34b are chamfered. By doing so, the high-pressure air (first mixed gas flow 35) discharged from the first opening 34a or the high-pressure air (second mixed gas flow 36) discharged from the second opening 34b is applied to the outer wall surface of the central column 17. easier to flow along. As a result, the swirl of high-pressure air (first mixed gas flow 35) discharged from the first opening 34a formed at the end of the central column 17 or high-pressure air (second mixed gas flow 36) discharged from the second opening 34b Energy loss due to the region 47 is suppressed, and the energy saving performance of the air blower 1 can be enhanced.

(4) The blower 1 has a third outlet 22 for blowing out high-pressure air (third airflow 33c) on another side of the central column 17, which is the same side as the first opening 34a or the second opening 34b. In addition, a first state in which high-pressure air (first airflow 33a, second airflow 33b) is blown out from the blower outlet 20 (first blower outlet 20a, second blower outlet 20b), and high-pressure air from the third blower outlet 22 (second The second state of blowing out the three airflows 33c), and the high-pressure air from the outlet 20 (the first outlet 20a, the second outlet 20b) and the third outlet 22 (the first airflow 33a, the second airflow 33b, the third airflow 33c) is configured to be switchable between the third state in which 33c) is blown out. As a result, according to the intended use of the blower device 1, a first state in which a desired area can be formed with air (purified and air-conditioned high-pressure air) that is beneficial to the user due to a high degree of suppression of the attraction of outside air; A second state in which the degree of suppression of the attraction of outside air is lower than that in the first state but in which the energy saving performance of the blower 1 can be improved, and the degree of suppression of the attraction of outside air and the energy saving performance of the blower device 1 can be compatible. It becomes possible to set the fan mode in any of the third states.

(5) In the air blower 1, the air purification filter 10 that purifies the air sucked from the suction port 9 is used as the characteristic imparting portion. By doing so, the first area 4 to which the first opening 34a is directed and the second area 5 to which the second opening 34b is directed are kept clean to the user while suppressing the attraction of outside air. It is possible to blow compressed air.

As a result, in the blower 1a, the blowing amount of the first mixture flow 35a blown out from the first opening 34a (hereinafter referred to as the first blowing amount) and the blowing amount of the second mixture flow 36a blown out from the second opening 34b (hereinafter referred to as the second air flow rate) is adjusted. That is, the amount of air blown by the first surface airflow 37c and the amount of air blown by the second surface airflow 38c are adjusted.

The wind direction adjusting unit 50 is a member that adjusts the first blowing direction of the first airflow 33a blown out from the first blowout port 20a and the second blowing direction of the second airflow 33b blown out from the second blowout port 20b. be. More specifically, the wind direction adjusting unit 50 includes a first louver 50a, a second louver 50b, a gripping rod 50c for adjusting the positions of the first louver 50a and the second louver 50b, and a stepping motor (not shown). and Also, the airflow direction adjusting unit 50 is installed at a predetermined position from the housing 6 side of the first internal airflow path 23 to the top plate 8 side.

The first louver 50a is a rectifying plate that is installed near the first blowout port 20a and straightens the blowing direction of the first airflow 33a blown out from the first blowout port 20a to the first blowing direction. The first louver 50a is adjusted by a grip rod 50c, and the first blowing direction is, for example, an oblique angle of 45 degrees on the side of the first area 4 (side of the first opening 34a) and the side of the second area 5 (side of the second opening 34b). 45 degrees diagonally. In FIG. 19, as an example, the first louver 50a is oriented at an angle of 45 degrees to the side of the first area 4 (the side of the first opening 34a).

The second louver 50b is a rectifying plate that is installed near the second air outlet 20b and rectifies the blowing direction of the second airflow 33b that blows off from the second air blowing outlet 20b to the second blowing direction. The second louver 50b, like the first louver 50a, is adjusted by the grip rod 50c, and the second blowing direction is, for example, an oblique angle of 45 degrees on the side of the first area 4 (side of the first opening 34a) and the side of the second area 5 ( It is possible to direct it between 45 degrees of the second opening 34b side). In FIG. 19, as an example, the second louver 50b is oriented at an angle of 45 degrees to the side of the first area 4 (the side of the first opening 34a).

The gripping rod 50c is a member that rotates about the vertical direction of the central column 17 (extending direction of the central column 17) as a rotation axis by a stepping motor (not shown) operated by a control signal from the control section. A first louver 50a and a second louver 50b are connected at predetermined positions to the grip rod 50c.

The wind direction adjusting unit 50 is configured as described above.

In the present embodiment, the direction of blowing airflow (the first blowing direction and the second blowing direction) is adjusted by the wind direction adjusting unit 50 so as to be biased toward the first opening 34a as shown in FIG. The first blowing amount of the first mixture flow 35a blown out from the one opening 34a can be made larger than the second blowing amount of the second mixture flow 36a blown out from the second opening 34b. In addition, by adjusting the blowing direction of the airflow (first blowing direction, second blowing direction) by the wind direction adjusting unit 50 so as to be biased toward the second opening 34b, the first mixed airflow blown out from the first opening 34a The first air flow rate of 35a can be made smaller than the second air flow rate of the second mixture flow 36a blown out from the second opening 34b. That is, in the air blower 1a, the air blowing direction is adjusted by the air direction adjusting unit 50, so that the balance of the amount of air supplied to the first area 4 and the second area 5 can be changed.

As described above, according to the blower device 1a according to the second embodiment, the following effects can be obtained in addition to the effects described above.

(6) In the blower device 1a, the first blowing direction of the high-pressure air (the first mixture flow 35) blown from the first blowout port 20a and the high-pressure air (the second mixture flow 36) blown from the second blowout port 20b ) are biased toward the same first opening 34a side (or the same second opening 34b side). This makes it possible to form a strong headwind against the direction in which the stronger disturbance wind flows, and suppress the inflow of the disturbance wind, that is, the attraction of the outside air. For example, when disturbance wind is generated to flow from the first opening 34a toward the second opening 34b, both the first blowing direction and the second blowing direction are set to the same side of the first opening 34a. The total component of the first blowing direction component of the high-pressure air (first airflow 33a) blown out from the first blowout port 20a and the first blowing direction component of the high-pressure air (second airflow 33b) blown out from the second blowout port 20b can be further enhanced.

(7) The blower device 1a includes a control unit that controls the blowing direction of the high-pressure air (the first airflow 33a and the second airflow 33b) blown from the blower outlets 20 (the first blower outlet 20a and the second blower outlet 20b). Prepare. The control unit controls the first blowing direction and the second blowing direction, and the first flow rate of high-pressure air (first mixed gas flow 35a) discharged from the first opening 34a and the amount of high-pressure air discharged from the second opening 34b The second feeding amount of the high-pressure air (the second mixture flow 36a) is adjusted. As a result, the relative relationship between the wind speed (first airflow rate) in the first area 4 to which the first opening 34a is directed and the wind speed (second airflow rate) in the second area 5 to which the second opening 34b is directed. can be appropriately adjusted during operation of the blower device 1a according to the intended use.

(Embodiment 3)
A blower device 1b according to Embodiment 3 of the present invention will be described with reference to FIGS. 20 to 22. FIG. FIG. 20 is a perspective view of a blower device 1b according to Embodiment 3 of the present invention. FIG. 21 is a structural diagram showing a cross section of an air blower 1b according to Embodiment 3. As shown in FIG. FIG. 22 is a schematic diagram showing the flow of air currents in the blower device 1b according to the third embodiment.

The blower 1b zones an open local space in an indoor space, forms a down-follow airflow (downward airflow) in the local space, and prevents dirty air in the local space from diffusing outside the local space. It is a restraining device. In other words, the air blower 1b reduces the risk of virus infection of the user who receives the airflow, and at the same time, even if the user includes a virus-infected person, the air blower 1b is designed to prevent the user from being blown out of the airflow range. It suppresses virus scattering to reduce the risk of infection of people outside the air blowing range. The blower 1b is preferably installed, for example, in a waiting space of a hospital, but may be installed as a place for communication with a small number of people, such as a meeting space in an office or a rest space. In addition, the air blower 1b can also be said to be an airflow environment system.

As shown in FIG. 20, the blower device 1b includes a housing 6a and a blowout section 7a.

The housing 6a is a member that supports the blowout part 7a together with the two struts 8a. The housing 6a is installed on the floor 61 in the open local space 4a.

Two suction ports 9a facing the local space 4a and an air cleaning filter 10a covering the suction ports 9a are provided on the floor surface 61 side of the housing 6a. Further, the housing 6a is provided with a blow-out portion 7a connected to the housing 6a on the side surface of the housing 6a on the ceiling surface 62 side (the side surface on the local space 4a side). The housing 6a also includes a high-pressure air generator (not shown) and an internal duct (not shown) in the internal space of the housing 6a. The high-pressure air generated by the high-pressure air generating section inside the housing 6a is sent to the blowout section 7a through the internal duct.

The suction port 9a is an opening for sucking the air in the local space 4a into the housing 6a.

The air purifying filter 10a is, for example, a HEPA filter, which removes dirt, dust, etc. contained in the air sucked into the housing 6a through the respective suction ports 9a, and outputs purified air. Here, the air purifying filter 10a is installed so as to block the flow path of air at each suction port 9a.

A space (hereinafter referred to as an external space 5a) is formed between the upper surface of the blowing part 7a and the ceiling surface 62 in a state where the blower 1b is installed on the floor surface 61 of the blowing part 7a. In addition, the external space 5a includes not only the space of this area but also the area other than the local space 4a, for example, the space of the surrounding area.

Then, the blowout part 7a generates a planar airflow (the entire airflow is a straight airflow in the blowing direction) as a downward airflow directed from the ceiling surface 62 side to the floor surface 61 in the local space 4a, and the ceiling surface 62 side airflow. Part of the air sucked from the local space 4a is discharged to the external space 5a.

Specifically, the blowout part 7a is configured with a plurality of hollow pillars 17a having the same role as the pillar 7 (central pillar 17) of the air blower 1 according to the first embodiment. The plurality of hollow pillars 17a are arranged side by side with a predetermined interval (gap) on the ceiling surface 62 side of the blower 1b, and extend along the ceiling surface 62 from the side surface of the housing 6a toward the pillar 8a side. It is formed by The plurality of hollow columns 17a all have the same length in the extending direction, and the vertical cross section in the extending direction is vertically long (a shape having a longitudinal width in the vertical direction and a short width in the horizontal direction). Further, as shown in FIG. 21, a first outlet 20a1 and a second outlet 20b1 are formed on each side surface of the plurality of hollow columns 17a.

More specifically, the hollow pillar 17a is formed with a first outlet 20a1 on the right side of the longitudinal width of the hollow pillar 17a. High-pressure air (first airflow 33a1, which will be described later) is blown out. On the other hand, the hollow pillar 17a is formed with a second outlet 20b1 on the left side of the longitudinal width of the hollow pillar 17a. Air (second airflow 33b1, which will be described later) is blown out. That is, each of the hollow columns 17a is formed with both the first outlet 20a1 and the second outlet 20b1. Note that the hollow columns 17a at the left and right outer ends are formed with the first outlet 20a1 or the second outlet 20b1 only on one side surface.

The first blowout port 20a1 and the second blowout port 20b1 are portions for blowing out high-pressure air from the high-pressure air generating section, and are formed by punching plates 21a having the same size and the same shape and having numerous opening holes. there is Also, the first outlet 20a and the second outlet 20b are provided so as to extend from the side of the housing 6a to the side of the column 8a (see FIG. 20). The first outlet 20a1 and the adjacent second outlet 20b1 are arranged at positions facing each other.

Moreover, as shown in FIG. 21, the plurality of hollow pillars 17a are divided into external air passages 32a by gaps between one hollow pillar 17a and the adjacent hollow pillar 17a (gap between two hollow pillars 17a). configure. A first opening 34a1 facing the local space 4a side (floor surface 61 side) and a second opening 34b1 facing the external space 5a side (ceiling surface 62 side) are formed in the external air passage 32a. . Here, the first opening 34a1 and the second opening 34b1 are formed to face each other.

The first opening 34a1 is an opening on the side facing the local space 4a in the external air passage 32a, and as shown in FIG. One of the air flows is blown out as the first mixed air flow 35a.

The second opening 34b1 is an opening on the side of the external air passage 32a that faces the external space 5a. It blows out as two mixed gas streams 36a. A punching plate 21b having a large number of opening holes is formed in the second opening 34b1. As a result, the opening area (ventilation area) of the second opening 34b1 becomes smaller than the opening area (ventilation area) of the first opening 34a1 by the punching plate 21b. In addition, the punching plate 21b corresponds to the "pressure loss output portion" in the claims.

More specifically, nine external air passages 32a are formed in the air blower 1b by ten hollow columns 17a. Then, the blower 1b blows out the first mixed gas flow 35b and the second mixed gas flow 36b from the first openings 34a1 and the second openings 34b1 respectively formed in the nine external air passages 32a. Here, since the punching plate 21b is provided on the side of the second opening 34b1, and the opening area (ventilation area) is small, it acts as a circulation resistance for the second air-fuel mixture flow 36b. Therefore, the first feeding amount of the first mixture flow 35b discharged from the first opening 34a1 becomes larger than the second feeding amount of the second mixture flow 36b discharged from the second opening 34b1.

Each of the first mixture flows 35a is blown out toward the floor surface 61 from the first openings 34a1. Then, the first mixed airflow 35b blown out from the first opening 34a1 flows toward the local space 4a as a first surface airflow 37d in which they are combined.

Each of the second mixed gas flows 36b is blown out from the second opening 34b1 toward the direction opposite to the first mixed gas flow 35b, that is, toward the ceiling 62. As shown in FIG. Then, the second mixed airflow 36b blown out from the second opening 34b1 flows toward the ceiling surface 62 as a second surface airflow 38d in which they are combined.

Since the first airflow 33a1 and the second airflow 33b1, which are the sources of the first surface airflow 37d, are purified high-pressure air, the temperature of the air in the external space 5a is harmful and uncomfortable to the human body. Also, users of the local space 4a can enjoy harmless and comfortable air.

In addition, in the blower device 1b, a part of the sucked air (for example, 20%) is blown out from the second opening 34b1 to the external space 5a with respect to the suction amount of the air sucked from the suction port 9a in the local space 4a. The blowing amount of the air (the first mixture flow 35b) blown out from the first opening 34a1 to the local space 4a is small. That is, in the air blower 1b, during the air blowing operation, "the suction amount of the suction port 9a > the blowing amount of the first opening 34a1", so the local space 4a (especially the area near the suction port 9a) is always in a negative pressure state. (Negative pressure) and attracts the surrounding air. This makes it easier to suck the air (first surface airflow 37d) descending through the local space 4a through the suction port 9a.

The air blower 1b forms an air flow as described above. In the air blower 1b, the open local space 4a is zoned to form a downdraft in the local space 4a while suppressing diffusion of dirty air in the local space 4a to the external space 5a.

In other words, the user who uses the desk 2a and the chair 3a is exposed to the first surface airflow 37d from overhead, which has a high degree of purification and a high wind speed. As a result, in the space where the blower 1b is installed, even if the air in the external space 5a contains a virus that causes an infectious disease, the user exposed to the airflow from the blower 1b will inhale the virus. It is possible to reduce the risk of infection due to

In addition, if there are multiple users of the blower 1b, and at least one of them suffers from an infectious disease, droplets containing the virus generated by the infected person's exhalation or sneezing can be used in an uninfected manner. There is also a risk of infection due to inhalation by humans. However, as described above, the droplets are forcibly knocked down toward the floor surface 61 and the suction port 9a by the high-speed first surface airflow 37d from overhead, so it is possible to reduce such risks. become.

As described above, according to the blower device 1b according to the third embodiment, in addition to the effects corresponding to the blower device 1 described above, the following effects can be obtained.

(8) In the blower 1b, part of the high-pressure air (the first mixed air flow 35b) purified by the air purification filter 10a is sent from the first opening 34a1 formed by the hollow column 17a to the floor surface 61 in the local space 4a. Blow it out. The second opening 34b1 blows out the rest of the high-pressure air (second mixed air flow 36b) purified by the air purification filter 10a toward the external space 5a.

With this configuration, the purified high-pressure air (the first surface airflow 37d consisting of the first mixed airflow 35b) flows down from the ceiling surface 62 side of the blower 1b. Aerosols, such as drifting viruses, can be lowered out of the user's breathing area. Then, the air (first surface airflow 37d) descending through the local space 4a is sucked from the suction port 9a, and part of the high-pressure air (first mixed airflow 35b) purified by the air purification filter 10a is discharged from the first opening 34a1 to the local area. When blowing out into the space 4a, the rest of the purified high-pressure air (second mixed gas flow 36b) is blown out from the second opening 34b1 into the external space 5a. It is possible to suppress diffusion of aerosols such as viruses floating in the air of the space 4a to the outside of the local space 4a (external space 5a). That is, the blower device 1b forms the first surface airflow 37d in the open local space 4a in the indoor space, and suppresses the contaminated air in the local space 4a from diffusing from the local space 4a to the external space 5a. can do

Although the present invention has been described above based on the embodiments, the present invention is by no means limited to the above-described embodiments, and various modifications and improvements are possible without departing from the scope of the present invention. can be easily guessed. Also, the configurations according to the respective embodiments may be combined within the applicable range.

In the blower device 1 according to the present embodiment, the air purification filter 10 and the air conditioning unit 13 are provided inside the housing 6, but the present invention is not limited to this. For example, the air purifying filter 10 and the air conditioning unit 13 are only described as an example of a uniqueness imparting unit that imparts a uniqueness different from that of the indoor air 31, and are not essential components of the blower device 1. A sex imparting part may be provided.

For example, a diffuser or the like that generates a scent that brings positive effects such as relaxation to the user may be provided as the uniqueness imparting unit. At this time, the air blower 1 has the feature that the user is less likely to be exposed to the induced airflow 39 containing the air (indoor air 31) of the external space 5a as described above, and therefore has the desired fragrance intensity. It is possible to reduce the amount of perfume required by the diffuser needed to deliver the airflow. Therefore, there is also the advantage that it is possible to reduce the running cost of the air blower 1 or the frequency of replenishment of perfume. Furthermore, as another characteristic imparting unit, a humidifier or dehumidifier for adjusting the humidity of the air may be provided.

Further, in the blower device 1 according to the present embodiment, by forming the first blower outlet 20a and the second blower outlet 20b with the punching plate 21 having the same size, the first airflow 33a and the second airflow 33b are generated at the same flow rate. (blowing volume). As a result, the flow rates of the first mixed airflow 35 and the second mixed airflow 36 after colliding with each other from the front are set to be equal, and the flow rates of the first surface airflow 37 and the second surface airflow 38 are also set to be equal. It is not limited to this. For example, the first blowout port 20a and the second blowout port 20b do not necessarily have to have the same dimensions, nor do they need to be punched plates 21 . However, by making the dimensions of the punching plate 21 the same, the flow rate or wind speed from the first blower outlet 20a and the second blower outlet 20b are set to be the same, and the adjacent first airflow 33a and second airflow 33b By increasing the opposing wind direction, it is possible to suppress the intensity of turbulence, which increases in proportion to the difference in wind speed, and create a comfortable airflow with a small sense of draft due to the small time fluctuation of the wind speed.

Furthermore, even in a situation where external disturbance wind containing outside air that tries to flow from the first opening 34a to the second opening 34b or from the second opening 34b to the first opening 34a is generated, The second airflow 33b flowing from the first opening 34a toward the second opening 34b against the disturbance wind trying to flow in from the first opening 34a toward the second opening 34b, the first airflow 33a flowing toward the second opening 34b The disturbance wind that is about to flow toward the opening 34a is blown out from each outlet and collides with it, thereby creating a headwind with an increased width of the airflow. It becomes possible to further suppress the attraction.

Moreover, although the air blower 1 according to the present embodiment has been described as a partition installed indoors, it is not limited to indoor use. The outdoor air may contain substances harmful to the human body (especially pollen or odors) as much as or more than the indoor air 31 and may be at an uncomfortable temperature. You can fully enjoy the effects.

Further, in the blower device 1 according to the present embodiment, the first airflow 33a blown out from the first blowout port 20a and the second airflow 33b blown out from the second blowout port 20b are configured to collide with each other. However, it is not limited to this. For example, only one of the first outlet 20 a and the second outlet 20 b may be provided for one external air passage 32 . The same effect can be enjoyed also by this.

Further, in the blower device 1 according to the present embodiment, the first blowing direction of the first airflow 33a and the second blowing direction of the second airflow 33b are on the same side (first opening 34a side or second opening 34b side). but not limited to this. For example, the first blowing direction and the second blowing direction may be different so that the first airflow 33a and the second airflow 33b do not collide with each other. Alternatively, an air passage biased toward the first opening 34a side and an air passage biased toward the second opening 34b side may be provided together with the external air passage 32 . By balancing the air volume, the same effect can be enjoyed in this way as well.

Further, in the blower device 1a according to the present embodiment, the wind direction adjusting section 50 is made movable, but the present invention is not limited to this. For example, the holding rod 50c that constitutes the wind direction adjusting unit 50 may be fixed in advance so that the blowing direction (first blowing direction, second blowing direction) is constant. The same effect can be enjoyed also by this.

INDUSTRIAL APPLICABILITY The air blowing device according to the present invention is useful because it can blow air imparted with characteristics beneficial to the user to a desired area while suppressing the attraction of outside air.
