[0003] [Patent Document 1] JP 2017-115629 A Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 discloses a blower device that has a plurality of nozzles in an atrium connecting the first and second floors of a house, with an air outlet facing towards the first floor, a housing (not shown) in the space between the first floor ceiling and the second floor floor, and an intake port in the first floor ceiling.

[0005] According to the blower device described in Patent Document 1, air near the ceiling on the first floor is taken in through the intake port and blown out through the outlet port to generate a blown-out airflow. As the blown-out airflow is generated, a negative pressure area is generated between the nozzles, but the air on the second floor becomes an induced airflow, and the induced airflow passes between the nozzles, alleviating the negative pressure area. As the negative pressure area is alleviated, the amount of blown-out airflow drawn into the negative pressure area is reduced, and a surface airflow is sent out to the first floor.

[0006] In order to generate an induced airflow, a certain distance must be secured between the nozzle and the ceiling surface, which poses a problem that the height of the blower is limited relative to the location where it can be installed.

[0007] The present invention is devised to solve the above-mentioned problems of the conventional art, and aims to provide a blower capable of generating a surface airflow, and a private booth equipped with the blower, which can alleviate the restrictions on the height of the blower in relation to the space in which it is placed. [Means for solving the problem]

[0008] In order to achieve this object, In one embodiment The blower includes a hollow columnar nozzle that stands on the wall surface as a base end and has a first outlet at a tip end for blowing out a first airflow, and a second outlet between adjacent nozzles for blowing out a second airflow. The nozzles are arranged in parallel in the short side direction of the nozzle. The second outlet is arranged on one end side of the long side direction of the nozzle. Effect of the Invention

[0009] According to the present invention, it is possible to provide a blower capable of generating a surface airflow, which can alleviate the restriction on the height of the blower in relation to the space in which the blower is placed, and a private booth equipped with the blower.

[0014] (200 private booths) The private booth 200 is a square-shaped housing that forms an internal space S where a user can stay depending on the purpose of the user, such as working or resting. The private booth 200 may have chairs 300, desks 400, etc. arranged in the internal space S depending on the purpose of the user. The private booth 200 includes a floor panel 210, a left side panel 220, a back panel 230, a top panel 240, a right side panel 250, and a front panel 260.

[0015] The floor board 210 is a flat board for forming the internal space S. The floor board 210 is disposed below the user when the user is seated on the chair 300. The floor board 210 can be made of a metal material, wood, resin material, or the like.

[0016] The left side plate 220 is a flat plate for forming the internal space S. The left side plate 220 stands vertically upward with the floor plate 210 as its base end. The left side plate 220 is disposed on the left side of the user when the user is seated on the chair 300. The left side plate 220 can be made of a metal material, wood, resin material, or the like. The left side plate 220 is disposed opposite the right side plate 250 in the internal space S.

[0017] The right side plate 250 is a flat plate for forming the internal space S. The right side plate 250 is placed on the right side of the user when the user is seated on the chair 300. The right side plate 250 can be made of a metal material, wood, resin material, or the like.

[0018] The back panel 230 is a flat panel for forming the internal space S. The back panel 230 stands vertically upward with the floor panel 210 as its base end. The back panel 230 is disposed on the back side of the user when the user is seated on the chair 300. The back panel 230 may be made of a metal material, wood, resin material, or the like. The back panel 230 is disposed opposite the front panel 260 in the internal space S.

[0019] The front panel 260 is a flat plate for forming the internal space S. The front panel 260 is disposed in front of the user when the user is seated on the chair 300. The front panel 260 can be made of a metal material, wood, a resin material, or the like.

[0020] The top plate 240 is a flat plate for forming the internal space S. The top plate 240 is disposed at the tip of the left side plate 220, the right side plate 250, the rear plate 230, and the front plate. The top plate 240 is disposed opposite the floor plate 210 in the internal space S. The top plate 240 is disposed above the user when the user is seated on the chair 300. The top plate 240 has an air intake port 241.

[0021] The air supply port 241 is an opening for connection to a first duct 10, which will be described later.

[0022] The private booth 200 defines an interior space S using a floor panel 210 , a left side panel 220 , a right side panel 250 , a rear panel 230 , a front panel 260 and a top panel 240 .

[0023] The internal space S does not have to be a completely sealed space (closed space). For example, the internal space S may be connected to the external space of the private booth 200 by a gap that occurs at the contact portion of each member that forms the internal space S.

[0024] A door (not shown) for allowing a user to enter and exit the private booth 200 may be provided on at least one of the left side panel 220, the right side panel, the back panel 230 and the front panel.

[0025] The private booth 200 may be either a stationary type or a portable type.

[0026] The above is the configuration of the private booth 200.

[0027] (Blower device 100) The blower device 100 is disposed in the internal space S, and generates a surface airflow from the top board 240 toward the floor board 210. The blower device 100 includes a first duct 10, a second duct 20, a first blower 30, an inlet 40, a third duct 50, a duct wall 60, a fourth duct 70, a second blower 80, and a nozzle 90.

[0028] The first duct 10 is an air transport path for transporting air in the external space of the private booth 200 to the first fan 30. The first duct 10 is connected to the air supply port 241 at one end and to the first fan 30 at the other end.

[0029] The second duct 20 is an air transport path for transporting the air transported to the first blower 30 via the first duct 10 to the nozzle 90. One end of the second duct 20 is connected to the first blower 30, and the other end is connected to the nozzle 90. The second duct 20 branches into a number corresponding to the number of nozzles 90. For example, when four nozzles 90 are arranged, the second duct 20 branches into four.

[0030] The first blower 30 generates an airflow F1 in the first duct 10 and the second duct 20. The first blower 30 has a first fan (not shown) and a first motor (not shown) that rotatably supports the fan. A known centrifugal impeller can be used as the first fan. A known AC motor or a known DC motor can be used as the first motor.

[0031] Inlet 40 is a square opening for communicating internal space S with third duct 50. Inlet 40 is disposed below chair 300, on the side of floor board 210. For example, when a user is seated on chair 300, inlet 40 is disposed near the user's feet.

[0032] The third duct 50 is a rectangular air transport passage for transporting air in the internal space S to the fourth duct 70 via the air inlet 40. The third duct 50 is disposed between the floor board 210 and the chair 300. The third duct 50 contains the first fan 30 and the second fan 80 therein.

[0033] The duct wall 60 is a flat plate for forming the fourth duct 70. The duct wall 60 is disposed opposite the rear plate 230 in the fourth duct 70. The duct wall 60 can be made of a metal material, wood, a resin material, or the like. The duct wall 60 has a second air outlet 61.

[0034] The second air outlet 61 is a square-shaped opening for communicating the internal space S with the fourth duct 70. The second air outlet 61 corresponds to the "second air outlet" which is a feature of the present invention. The second air outlet 61 is disposed between adjacent nozzles 90 and at one end side of the nozzle 90 in the long side direction. The number of second air outlets 61 disposed is at least the number corresponding to the number of nozzles 90. For example, when four nozzles 90 are disposed, at least four second air outlets 61 are disposed. Note that the opening shape of the second air outlet 61 is represented as a square shape in this embodiment, but it may be a round shape or other angular shape.

[0035] The fourth duct 70 is a square-shaped air transport path for transporting the air in the internal space S transported via the third duct 50 to the second air outlet 61. The fourth duct 70 is disposed between the duct wall 60 and the back panel 230. One end of the fourth duct 70 is connected to the third duct 50, and the other end is connected to the second air outlet 61.

[0036] The second blower 80 generates an airflow F2 in the third duct 50 and the fourth duct 70. The second blower 80 has a second fan (not shown) and a second motor (not shown) that rotatably supports the fan. A known centrifugal impeller can be used as the second fan. A known AC motor or a known DC motor can be used as the second motor.

[0037] The nozzle 90 is a hollow columnar air transport passage for transporting air from the external space of the private booth 200, which has been transported through the second duct 20, to the internal space S. The nozzle 90 corresponds to the "nozzle" which is a feature of the present invention. The nozzle 90 stands with the top plate 240 as a base end, and is formed so that the direction between the front plate 260 and the back plate 230 is the long side, and the direction between the right plate 250 and the left plate 220 is the short side. The nozzles 90 are arranged in parallel and at equal intervals in the direction between the right plate 250 and the left plate 220. That is, the nozzles 90 are arranged in parallel and at equal intervals in the direction of the short side of the nozzle 90. In the first embodiment, four nozzles 90 are arranged in parallel. The base end of the nozzle 90 is in contact with the top plate 240. The nozzle 90 has an opening (not shown) for communicating with the second duct 20, and a first blowing outlet 91 at the tip. The top plate 240 corresponds to a "wall surface" in the claims.

[0038] The first air outlet 91 is a square opening for blowing out the airflow F1. The first air outlet 91 corresponds to the "first air outlet" which is a feature of the present invention. The first air outlet 91 communicates with the nozzle 90 and the internal space S. The first air outlet 91 is formed such that the long side is in the direction between the front plate 260 and the back plate 230 and the short side is in the direction between the right plate 250 and the left plate 220. Adjacent first air outlets 91 are preferably arranged to be at approximately the same height.

[0039] The configuration of the blower device 100 has been described above.

[0040] (Features of the blower 100) When the operation of the blower device 100 is started, an airflow F1 is generated by the first blower 30, and an airflow F2 is generated by the second blower 80. The airflow F1 is blown out from the first air outlet 91 into the internal space S. The airflow F2 is blown out from the second air outlet 61 into the internal space S. When the airflow F1 is blown out from the first air outlet 91, air in the space around the airflow F1 is pulled by the airflow F1, and a negative pressure region P is generated in the space between adjacent nozzles 90.

[0041] Here, as a comparative example, the airflow F1 will be described with reference to FIG. 4(b) on the assumption that the duct wall 60 does not have the second air outlet 61. When a negative pressure region P is generated in the space between the adjacent nozzles 90, a force acts to eliminate the negative pressure region P, and the airflow F1 is attracted to the negative pressure region P. Because the nozzles 90 are in contact with the top plate 240, the blower device 100 cannot guide air (induced airflow) for eliminating the negative pressure region P from the space above the top plate 240 to the negative pressure region P. Therefore, the amount of the airflow F1 attracted to the negative pressure region P is larger than when there is an induced airflow, and the airflow F1 is prevented from becoming an airflow linear in the blowing direction (in the present application, this airflow may be referred to as a "surface airflow" or a "surface airflow").

[0042] Next, the case where the duct wall 60 has the second air outlet 61, that is, the generation of F1 and surface airflow in the blower 100 of the present invention will be described with reference to FIG. 4(a). When a negative pressure area P is generated in the space between the adjacent nozzles 90, a force that tries to eliminate the negative pressure area P acts, as in the comparative example. In the case of the blower 100, the airflow F2 blown out from the second air outlet 61 enters the negative pressure area P, so that the negative pressure area P becomes smaller. By reducing the negative pressure area P, the amount of the airflow F1 drawn to the negative pressure area P becomes smaller than when there is no airflow F2, so that the generation of the surface airflow by the airflow F1 becomes easier. In other words, since the blower 100 has the second air outlet 61, it is not necessary to secure a height (space) between the nozzle 90 and the top plate 240 to generate an induced airflow. This makes it possible for the blower device 100 to alleviate the restriction on the height of the blower device 100 in order to generate a surface airflow with respect to the space in which the blower device 100 is placed (in this embodiment, the internal space S formed in the private booth 200).

[0043] [Variation 1] The following describes Modification 1 of Embodiment 1. In the description of Modification 1, the same components and members as those of Embodiment 1 are given the same reference numerals. Descriptions that overlap with those of Embodiment 1 will be omitted as appropriate, and the description will focus on the configuration that differs from that of Embodiment 1.

[0044] Although the blower device 100 is configured to include the first blower 30 and the second blower 80, the present invention is not limited thereto. The blower device 100 may be configured to include either the first blower 30 or the second blower 80 and to be capable of generating the airflow F1 and the airflow F2. For example, when the blower device 100 does not include the second blower 80, the first blower 30 has an outlet (opening) communicating with the third duct 50, so that the first blower 30 alone can generate the airflow F1 and the airflow F2. At this time, the first blower 30 may have an airflow adjustment plate (damper) for adjusting the amount of the airflow F1 and the amount of the airflow F2. Furthermore, when the blower device 100 does not include the first blower 30, the second blower 80 is connected to the first duct 10 and the second duct 20, so that the second blower 80 alone can generate the airflow F1 and the airflow F2. In this case, the second fan 80 may have an air volume adjustment plate (damper) for adjusting the volume of the airflow F1 and the volume of the airflow F2.

[0045] The blower device 100 may further include a filter for collecting dust, pollen, and the like contained in the airflows F1 and F2. For example, by providing a filter in the first duct 10 and the air inlet 40, the amount of dust and pollen contained in the airflows F1 and F2 after passing through the filter can be made smaller than that before passing through the filter. This makes it possible to purify the air in the internal space S by using the airflows F1 and F2.

[0046] The air blower 100 may further include a functional component generating unit for adding functional components (components for sterilization, fragrance, and deodorization) to the airflows F1 and F2. This makes it possible to sterilize, fragrance, and deodorize the internal space S by using the airflows F1 and F2.

[0047] The blower 100 may further include an air conditioner that performs air conditioning (at least one of heating, cooling, humidification, and dehumidification) on at least one of the airflows F1 and F2. An example of the air conditioner is an air conditioner. This makes it possible to control the temperature and humidity of the airflows F1 and F2, which is expected to have the effect of improving the comfort of the user staying in the internal space S.

[0048] Although the blower 100 is disposed in the internal space S of the private booth 200, the present invention is not limited to this. For example, the blower 100 may be disposed in an office space that is larger than the private booth 200 and can accommodate a large number of people.

[0049] The nozzle 90 is arranged to be in contact with the top plate 240, but is not limited to this. For example, a predetermined spatial distance (gap) may be provided between the top plate 240 and the base end of the nozzle 90. The predetermined distance is, for example, a distance (gap) that does not generate an induced airflow that is effective in eliminating the negative pressure region P when generating a surface airflow.

[0050] The floor plate 210 may have an exhaust port for exhausting a part of the air in the internal space S to the space outside the private booth 200. In this case, the second blower 80 communicates with the exhaust port and can exhaust a part of the air in the internal space S sucked in from the intake port 40 to the space outside the private booth 200. The amount of the airflow F2 generated by the second blower 80 and the amount of air exhausted to the space outside the private booth 200 can be adjusted by the ratio of the opening area of ​​the exhaust port to the opening area of ​​the third duct and the fourth duct. The adjustment of the ratio of the opening area of ​​the exhaust port to the opening area of ​​the third duct and the fourth duct can be realized, for example, by employing a known air volume adjustment plate (damper) provided on the second blower 80.

[0051] (Embodiment 2) The configuration of the air blower 100a according to the second embodiment of the present invention and the private booth 200a equipped with the air blower 100a will be described with reference to Figures 5 to 9. Note that in Figures 5 to 9, the same components as those in Figures 1 to 4 are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0052] FIG. 5 is a perspective view showing the configuration of a blower and a private booth according to a second embodiment of the present invention. FIG. 6 is a top view showing the configuration of a blower 100a and a private booth 200a according to a second embodiment of the present invention. FIG. 7 is a rear view showing the configuration of a blower 100a and a private booth 200a according to a second embodiment of the present invention. FIG. 8 is a side view showing the configuration of a blower 100a and a private booth 200a according to a second embodiment of the present invention. FIG. 9 is an enlarged cross-sectional view showing in detail the configuration of a nozzle provided in the blower 100a according to the second embodiment of the present invention.

[0053] (Private booth 200a) The private booth 200a has the same configuration as the private booth 200, so a detailed description thereof will be omitted.

[0054] (Blower device 100a) The configuration of blower device 100a is different from that of blower device 100 in that it does not include second air outlet 61, does not include second blower 80, and includes nozzle 90a, but otherwise has the same configuration as blower device 100.

[0055] The nozzle 90a is a hollow columnar air transport passage for transporting the air in the external space of the private booth 200a, which has been transported through the second duct 20, to the internal space S. The nozzle 90a corresponds to the "nozzle" which is a feature of the present invention. The nozzle 90a stands with the top plate 240 as its base end, and is formed so that the direction between the front plate 260 and the back plate 230 is the long side, and the direction between the right plate 250 and the left plate 220 is the short side. The nozzles 90a are arranged in parallel and at equal intervals in the direction between the right plate 250 and the left plate 220. That is, the nozzles 90a are arranged in parallel and at equal intervals in the direction of the short side of the nozzles 90a. In the second embodiment, four nozzles 90a are arranged in parallel. The base end of the nozzle 90a is in contact with the top plate 240. The nozzle 90a has an opening (not shown) for communicating with the second duct 20, and a first air outlet 91a at its upright tip.

[0056] The first air outlet 91a is a square-shaped opening for blowing out the airflow F1. The first air outlet 91a corresponds to the "air outlet" which is a feature of the present invention. The first air outlet 91a communicates the nozzle 90a with the internal space S. The first air outlet 91a is formed so that the long side is in the direction between the front plate 260 and the back plate 230, and the short side is in the direction between the right side plate 250 and the left side plate 220. It is preferable that the adjacent first air outlets 91 are arranged so as to be at approximately the same height. Here, a division line L is assumed to divide the length of the long side of the nozzle 90a exposed to the internal space S. The division line L divides the length L1 of the long side of the nozzle 90a at a ratio of A:B. When the side of the dividing line L toward the front plate 260 is defined as one end, and the side of the dividing line L toward the rear plate 230 is defined as the other end, the first air outlet 91a is disposed on the side of the front plate 260 from the dividing line L, i.e., on the one end side of the nozzle 90a. The first air outlet 91a opens from the dividing line L toward the front plate 260. In other words, the length of the long side of the first air outlet 91a is calculated by B×L1÷(A+B). The ratio of division by the dividing line L is preferably in the range of A:B=1:4 to A:B=1:1.

[0057] The above is the configuration of the blower device 100a.

[0058] (Features of the blower device 100a) When the blower device 100a starts operating, an airflow F1 is generated by the first blower 30. The airflow F1 is blown out from the first blower port 91a into the internal space S. When the airflow F1 is blown out from the first blower port 91a, the air in the space around the airflow F1 is pulled by the airflow F1, and a negative pressure region P is generated in the space between the adjacent nozzles 90a. When a negative pressure region P is generated in the space between the adjacent nozzles 90a, a force that tries to eliminate the negative pressure region P acts, as in the first embodiment. In the case of the blower device 100a, an induced airflow F3 that flows into the negative pressure region P is generated from the other end side of the nozzle 90a, i.e., the side where the first blower port 91a is not arranged, into the space between the adjacent nozzles 90a. When the airflow F3 flows into the negative pressure region P, the negative pressure region P becomes smaller. That is, the induced airflow F3 suppresses the force of the adjacent airflows F1 being drawn to the negative pressure region P and merging. Therefore, the blower 100a can easily generate an airflow in which the merging of the adjacent airflows F1 is suppressed, that is, an airflow (surface airflow) in which the airflow F1 is linear in the blowing direction. That is, the blower 100a has the first air outlet 91a disposed at one end side in the long side direction of the nozzle 90a, so that the induced airflow is generated in the space between the adjacent nozzles 90a at the other end side, and therefore there is no need to ensure a height (space) for generating the induced airflow between the nozzle 90 and the top plate 240. This makes it possible to alleviate the restriction on the height of the blower 100a for generating a surface airflow with respect to the space in which the blower 100a is disposed (in this embodiment, the internal space S formed in the private booth 200a).

[0059] In addition, since the air blowing device 100a generates a surface airflow toward the space below the first air outlet 91a rather than toward the entire interior space S, it is possible to provide a surface airflow toward a desired location (e.g., a desk 400).

[0060] [Variation 2] The following describes Modification 2 of Embodiment 2. In the description of Modification 2, the same or equivalent components and members as those of Embodiment 2 are given the same reference numerals. Descriptions that overlap with those of Embodiment 2 will be omitted as appropriate, and the description will focus on the configuration that differs from that of Embodiment 2.

[0061] In the blower device 100a, the first blower outlet 91a is configured to be disposed on one end side of the nozzle 90a, but is not limited thereto. The first blower outlet 91a may be disposed on the other end side of the nozzle 90a. When the first blower outlet 91a is disposed on the other end side of the nozzle 90a, the other end side corresponds to the one end side described in the claims of the present application. When the first blower outlet 91a is disposed on the other end side of the nozzle 90a, the blower device 100a generates a surface airflow toward the space below the first blower outlet 91a, not toward the entire internal space S, and thus provides a surface airflow to the chair 300.

[0062] The present invention has been described above based on the embodiment. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each processing process, and that such modifications are also within the scope of the present invention.
