[0009] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to FIGS.

[0011] [1-1.Configuration] Fan device 100 is placed in an indoor space such as an office and generates an airflow that blows from the ceiling toward the floor. 1 to 3, fan device 100 includes side panel 110, chamber 120, a plurality of louvers 130, airflow guide section 140, duct 150, fan 160, and support frame 170.

[0012] [1-1-1. Side panel] The side panel 110 will be described with reference to Figures 1 to 3. The side panel 110 is a housing formed by assembling a plurality of planks of wood or the like, and is installed facing upward. "Installed facing upward" means that the side panel 110 stands upright from the floor surface toward the ceiling surface in an indoor space. The side panel 110 has an intake space 111 and an intake port 112.

[0013] The suction space 111 is a space for arranging the duct 150 and the blower 160 inside the side panel 110. The suction space 111 is formed by assembling the side panels 110.

[0014] Air inlet 112 is provided below side panel 110 and is an opening for drawing air into blower 160. "The front surface of side panel 110" refers to front panel 110a among the plates that make up side panel 110. In other words, air inlet 112 is provided in front panel 110a. "Below" refers to the position closer to the floor than the head of a seated person in an indoor space, specifically a position 130 cm above the floor. Air inlet 112 is rectangular and has upper end 112a, lower end 112b, one side end 112c, and the other side end 112d.

[0015] The upper end 112a is a horizontal side.

[0016] The lower end 112b is a side provided below the upper end 112a.

[0017] One side end 112c is a side provided on one side end of upper end 112a and lower end 112b. In other words, one side end 112c is a side provided on one side end of side panel 110 in the rectangular opening.

[0018] The other end 112d is a side located on the other end side of the upper end 112a and the lower end 112b. In other words, the other end 112d is a side provided on the other end side of the side panel 110 in the rectangular opening.

[0019] Suction port 112 is rectangular in shape with upper end 112a and lower end 112b as long sides and one side end 112c and the other side end 112d as short sides.

[0020] One side end 112c provided at the end of one side end of side panel 110 at suction port 112 is provided closer to the other side end of side panel 110 than louver 130 arranged at one side end of side panel 110.

[0021] The other end 112d of the air inlet 112 provided at the end of the other end of the side panel 110 is provided closer to one end of the side panel 110 than the louver 130 arranged at the other end of the side panel 110.

[0022] [1-1-2. Chamber] The chamber 120 will be described with reference to FIG. 2 and FIGS. 4 to 7. The chamber 120 is a housing that connects to the louvers 130 and the duct 150. One chamber 120 is connected to each louver 130. The chamber 120 is disposed above the side panel 110. The chamber 120 controls the airflow (airflow direction) from the duct 150 to the louvers 130. The chamber 120 is formed into a rectangular parallelepiped (rectangular hexahedron) using metal processing techniques such as punching, bending, and welding on sheet metal. The chamber 120 has an upper surface 121, a lower surface 122, side surfaces 123, a first hollow space 124, a rectifying vane 125, and a duct connection portion 126.

[0023] The upper surface 121 is a flat plate disposed above the lower surface 122 with the first hollow space 124 therebetween.

[0024] The lower surface 122 is a flat plate disposed below the upper surface 121 with the first hollow space 124 sandwiched therebetween. The lower surface 122 has an air supply opening 122a.

[0025] The air supply opening 122a is a hole that connects the duct 150 and the chamber 120. The air supply opening 122a has a shape similar to the shape of the current plate 125 projected horizontally onto the lower surface 122, and is formed in a rectangular shape.

[0026] The side surface 123 is a flat plate that stands up from the peripheral edge of the lower surface 122. Four side surfaces 123 are arranged, but two are shown in FIG. 4. One of the four side surfaces 123, side surface 123a, is connected to the louver 130. Side surface 123a has an air blowing opening 123b and a pressurization hole 123c.

[0027] Air outlet 123b is a hole that connects an upper louver space of louver 130 (described later) with first hollow space 124. Air outlet 123b is formed by cutting and raising rectifying plate 125 from side surface 123 using metal processing technology.

[0028] The pressurizing hole 123c is a hole that communicates a lower louver space of the louver 130, which will be described later, with the first hollow space 124. The pressurizing hole 123c is formed by stamping metal or the like.

[0029] The first hollow space 124 is a ventilation passage formed by the upper surface 121, the lower surface 122, and the side surface 123.

[0030] The rectifying vane 125 is a rectangular flat plate that stands up from the side surface 123a toward the first hollow space 124. The standing direction of the rectifying vane 125 is preferably parallel to the lower surface 122. The rectifying vane 125 is formed by cutting out from the side surface 123a using metal processing technology. The shape of the rectifying vane 125 when projected horizontally onto the lower surface 122 is similar to the shape of the air intake opening 122a. The standing tip of the rectifying vane 125 is arranged with a predetermined distance (for example, 10 cm) between the side surface 123a and the side surface 123 opposite to the side surface 123a.

[0031] The duct connector 126 is a circular pipe that stands downward (toward the floor surface) from the lower surface 122. By inserting the duct connector 126 into the duct 150, the duct 150 and the chamber 120 are connected.

[0032] [1-1-3. Louver] The louvers 130 will be described with reference to FIGS. 1-2 and 4-8. The louvers 130 are a type of rectangular ventilation pipe that starts from the upper portion of the side panel 110 and extends horizontally from the side surface 123a of the chamber 120, through which air transported from the chamber 120 flows. "Above the side panel 110" refers to a position higher than the head of a standing person, specifically, a position at least 200 cm above the floor in an indoor space. "Extended horizontally" refers to an upright position that is approximately parallel to the floor and ceiling in an indoor space. Eight louvers 130 are arranged in parallel from one end to the other end of the side panel 110. The louvers 130 are preferably arranged at equal intervals. The louvers 130 include a first outer louver 131, a second outer louver 132, a second hollow space 133, and an air outlet 134.

[0033] The first outer louvers 131 are generally C-shaped in cross section in the short direction, and are formed by extending the C-shape in the longitudinal direction. The opening ends of the first outer louvers 131 abut against the opening ends of the second outer louvers 132.

[0034] The second outer louvers 132 are generally inverted C-shaped in cross section in the short side direction, and are formed by extending the generally inverted C-shape in the longitudinal direction. The second outer louvers 132 have their opening ends abutting against the opening ends of the first outer louvers 131.

[0035] The second hollow space 133 communicates with the first hollow space 124 via the air blowing opening 123b and the pressurization hole 123c of the chamber 120. The second hollow space 133 is formed by the substantially C-shaped inner peripheral wall of the first outer louver 131 and the substantially inverted C-shaped inner peripheral wall of the second outer louver 132 when the open end of the first outer louver 131 and the open end of the second outer louver 132 are in contact with each other. The second hollow space 133 has an upper louver space 133a and a lower louver space 133b.

[0036] The upper louver space 133a is one of the spaces formed by dividing the second hollow space 133 by the airflow guiding section 140, and is disposed above the airflow guiding section 140. The upper louver space 133a communicates with the first hollow space 124 of the chamber 120 via the air blowing opening 123b.

[0037] The lower louver space 133b is one of the spaces formed by dividing the second hollow space 133 by the airflow guiding section 140, and is disposed below the airflow guiding section 140. The lower louver space 133b communicates with the first hollow space 124 of the chamber 120 via the pressurization hole 123c.

[0038] The air outlet opening 134 is an opening for blowing out air that has flowed into the upper louver space 133a. In other words, the air passage from the chamber 120 to the air outlet opening 134 is formed by the air outlet opening 123b and the upper louver space 133a. In other words, the lower louver space 133b does not belong to the air passage from the chamber 120 to the air outlet opening 134. The air outlet opening 134 is provided on the side of the louver 130 that faces downward and is adjacent to the side surface 123a of the chamber 120. "Facing downward" refers to facing directly to the floor in an indoor space. In other words, the air outlet opening 134 is provided on the surface of the rectangular louver 130 that faces directly to the floor. The air outlet opening 134 is a rectangular opening, and is formed so that the long side is in the upright direction and the short side is parallel to the side panel 110. One air outlet opening 134 is provided for each louver 130. When a certain horizontal plane is imagined, the air outlet openings 134 belonging to each louver 130 are preferably arranged on the same plane. In other words, in an indoor space, the air outlet openings 134 belonging to each louver 130 are preferably arranged at the same height from the floor. The air outlet opening 134 is formed by abutting the open end of the first outer louver 131 and the open end of the second outer louver 132.

[0039] [1-1-4. Airflow guidance section] The airflow guiding section 140 will be described with reference to Fig. 6 and Figs. 9 and 10. The airflow guiding section 140 is a component that divides the second hollow space 133 into an upper louver space 133a and a lower louver space 133b, and connects the upper louver space 133a with the outlet opening 134. The airflow guiding section 140 has a substantially V-shape when viewed in cross section in the short side direction, and is formed by extending the substantially V-shape in the longitudinal direction. The airflow guiding section 140 has an guiding opening 141, a partition clip 142, and a slit 143.

[0040] The guide opening 141 is a rectangular opening provided at the tip of the substantially V-shaped airflow guide portion 140, and is formed to extend in the longitudinal direction of the airflow guide portion 140. The guide opening 141 communicates between the upper louver space 133a and the blow-out opening 134.

[0041] Partition clip 142 is a flat component that has a portion thereof penetrating air flow guiding portion 140 via slit 143, and that secures air flow guiding portion 140 to louver 130. Multiple partition clips 142 are arranged at equal intervals in the longitudinal direction of air flow guiding portion 140.

[0042] The slits 143 are rectangular holes for passing the partition clips 142 through the airflow guiding portion 140. A plurality of the slits 143 are provided at equal intervals in the longitudinal direction of the airflow guiding portion 140.

[0043] [1-1-5. Duct] The duct 150 will be described with reference to Figures 2 and 5. The duct 150 is an air duct for transporting air drawn into the blower 160 from the air inlet 112 to the chamber 120. One end of the duct 150 is connected to the chamber 120, and the other end is connected to the blower 160. One duct 150 is provided for each chamber 120. That is, eight ducts 150 are provided. For example, a known flexible duct is used as the duct 150.

[0044] [1-1-6. Blower] The blower 160 will be described with reference to Figure 2. The blower 160 generates an airflow that flows from the air inlet 112 through the duct 150 and the chamber 120 toward the outlet opening 134 of the louver 130. The blower 160 employs a known turbomachine such as a centrifugal blower. Four blowers 160 are provided, and the airflow generated by each blower 160 is conveyed to the two louvers 130.

[0045] [1-1-7. Support frame] The support frame 170 will be described with reference to FIGS. 1 to 3. The support frame 170 is a member for supporting the louvers 130. The support frame 170 is formed from two support posts 170a and one support rod 170b. The support post 170a is a square timber that stands upright from the floor surface in an indoor space. The support rod 170b is a square timber that is placed at the upright tip of the support post 170a. The support rod 170b is connected to the upright tip sides of the eight louvers 130.

[0046] [1-2. Operation] An example of the operation of blower 100 will be described with reference to Figures 2, 3, and 5. When blower 160 starts operating, air in the indoor space where blower 100 is installed becomes airflow AF1 and is sucked in through air inlet 112. The air sucked in through air inlet 112 (airflow AF1) passes through duct 150 and is transported to chamber 120. The airflow direction of the air transported to chamber 120 (airflow AF1) is controlled by chamber 120. That is, chamber 120 switches the traveling direction of airflow AF1 from a vertical direction (from the floor side to the ceiling side) to a horizontal direction. At the same time, the rectifying vane 125 divides part or all of the airflow AF1 into an upper airflow AF1a that flows into the upper louver space 133a from above the rectifying vane 125 and a downward airflow AF1b that flows into the upper louver space 133a from below the rectifying vane 125. The upper airflow AF1a and the downward airflow AF1b that flow into the upper louver space 133a pass between adjacent partition clips 142 and are blown out downward, i.e., toward the floor, from the outlet opening 134 through the guide opening 141. At this time, most of the downward airflow AF1b is blown out from the outlet opening 134 on the side where the louver 130 starts (the side of the side surface 123a of the chamber 120) relative to the upper airflow AF1a. In other words, the upper airflow AF1a is blown out from the outlet opening 134 on the upright tip side of the louver 130 relative to the downward airflow AF1b.

[0047] When airflow AF1, which includes an upper airflow AF1a and a lower airflow AF1b, is blown out from the outlet opening 134, air in the space around the airflow AF1 is attracted toward the airflow AF1, generating a negative pressure region S1 in the space between adjacent louvers 130. Negative pressure (also called negative pressure) refers to a state in which the air pressure is lower than the surroundings. In other words, the negative pressure region S1 is an area where the air pressure is lower than the surroundings. When the negative pressure region S1 is generated, a force acts to eliminate the negative pressure, and an airflow AF2 is generated in the space around the louvers 130 to eliminate the negative pressure region S1. The airflow AF2 is also called an induced airflow. The airflow AF2 suppresses the force that attracts the adjacent airflows AF1 toward the negative pressure region S1 and causes them to merge. Therefore, blower 100 generates an airflow AF3 in which the merging of adjacent airflows AF1 is suppressed, i.e., an airflow AF3 that is linear in the blowing direction as a whole (in the present application, this airflow may be referred to as a "planar airflow" or "planar airflow"). The air (airflow AF1) blown downward from outlet opening 134 is sucked into air inlet 112.

[0048] Because a gap is formed between the partition clip 142 and the slit 143 due to dimensional tolerances, the upper louver space 133a and the lower louver space 133b communicate with each other through the gap. Therefore, the airflow AF1 also tries to flow into the lower louver space 133b. The lower louver space 133b communicates with the first hollow space 124 via the pressurization hole 123c, so the airflow AF1c flows into the lower louver space 133b. The airflow AF1c is part of the airflow AF1. As the airflow AF1c flows into the lower louver space 133b, the pressure in the lower louver space 133b approaches the pressure in the upper louver space 133a. In other words, the pressure difference between the upper louver space 133a and the lower louver space 133b becomes smaller. Since airflow has the property of flowing from an area of ​​high pressure to an area of ​​low pressure, compared to when airflow AF1c does not flow into lower louver space 133b, the amount of airflow AF1 that flows into lower louver space 133b is smaller than the amount of airflow AF1 that passes through the air passage from air-blowing opening 123b to outlet opening 134. Therefore, turbulence of the airflow caused by airflow AF1 flowing into lower louver space 133b is reduced, and stable airflow AF1 is blown out from outlet opening 134.

[0049] [1-3. Effects, etc.] Blower device 100 includes chamber 120 having air blowing opening 123b on one surface (side surface 123a), louver 130 standing from one surface (side surface 123a) and having a hollow space (second hollow space 133) communicating with air blowing opening 123b and having air outlet opening 134 on a side surface adjacent to one surface (side surface 123a), and airflow guiding section 140 dividing the hollow space (second hollow space 133) into upper louver space 133a and lower louver space 133b and communicating upper louver space 133a with air outlet opening 134. Airflow guiding section 140 includes partition clip 142 for fixing airflow guiding section 140 to louver 130 and slit 143 for passing partition clip 142 through which airflow guiding section 140 is fixed to louver 130. The chamber 120 has a pressurizing hole 123c that communicates with the lower louver space 133b.

[0050] As a result, when airflow AF1 reaches outlet opening 134 from chamber 120, airflow AF1c, which is a part of airflow AF1, enters lower louver space 133b from pressurization hole 123c, thereby reducing the pressure difference between upper louver space 133a and lower louver space 133b. Therefore, airflow AF1 flows into lower louver space 133b, causing less turbulence in the airflow, and airflow AF1 can be blown out from outlet opening 134.

[0051] The air passage from chamber 120 to blow-out opening 134 is formed by air-blowing opening 123b and upper louver space 133a. In addition, lower louver space 133b does not belong to the air-blowing passage.

[0052] As a result, when airflow AF1 reaches outlet opening 134 from chamber 120, airflow AF1c, which is a part of airflow AF1, enters lower louver space 133b from pressurization hole 123c, thereby reducing the pressure difference between upper louver space 133a and lower louver space 133b. Therefore, airflow AF1 flows into lower louver space 133b, causing less turbulence in the airflow, and airflow AF1 can be blown out from outlet opening 134.

[0053] The louvers 130 have a first outer louver 131 that has a substantially C-shape when viewed in cross section in the short side direction and that extends in the longitudinal direction, and a second outer louver 132 that has a substantially inverted C-shape when viewed in cross section in the short side direction and that extends in the longitudinal direction. The air outlet opening 134 is formed by abutting the open end of the first outer louver 131 and the open end of the second outer louver 132. The hollow space (second hollow space 133) of the louver 130 is formed by the inner peripheral wall of the substantially C-shape of the first outer louver 131 and the inner peripheral wall of the substantially inverted C-shape of the second outer louver 132 in the abutting state.

[0054] This makes it possible to easily form the second hollow space 133 and the air outlet openings 134 compared to when the louver 130 is manufactured without being divided into the first outer louver 131 and the second outer louver 132. Therefore, it is expected that the manufacturing cost of the louver 130 can be reduced.

[0055] The airflow guide section 140 has a substantially V-shape in cross section in the short side direction, and is formed by extending the substantially V-shape in the longitudinal direction, and is provided with a guide opening 141 at the tip of the substantially V-shape, which connects the upper louver space 133a and the blow-out opening 134. The guide opening 141 abuts against the blow-out opening 134.

[0056] As a result, the air passage gradually narrows toward the induction opening 141 (toward downstream), and the airflow AF1 becomes a flow that narrows as it moves downstream (a converging flow). In a converging flow, the area of ​​the flow path decreases as it moves downstream, so the airflow gradually increases in speed. As a fluid increases in speed, its kinetic energy increases and its pressure decreases, so the pressure decreases downstream. In other words, the airflow AF1 moves from upstream, where pressure is high, to downstream, where pressure is low, and so it becomes a natural flow and a stable airflow. Then, by bringing induction opening 141 into contact with outlet opening 134, the stable airflow AF1 can be immediately blown out from outlet opening 134.

[0057] (Variation) The following are examples of modified examples.

[0058] [2-1.Configuration] Detailed description of the same configuration as in the first embodiment will be omitted, and only the configuration different from the first embodiment will be described.

[0059] In blower device 100, a filter for collecting dust contained in the air drawn into inlet 112 may be disposed at inlet 112 or downstream of inlet 112.

[0060] In the first embodiment, four fans 160 are provided, but the present invention is not limited to this. Two fans 160 may be provided, and an airflow generated by one fan 160 may be conveyed to four louvers 130.

[0062] In the first embodiment, the support columns 170a and the support rods 170b that make up the support frame 170 are made of square material, but this is not limiting. The support columns 170a and the support rods 170b may also be made of round bar material.

[0063] In the first embodiment, the rectifying plate 125 is formed by cutting and raising from the side surface 123a, but this is not limiting. The rectifying plate 125 may be formed independently of the side surface 123a and connected to the side surface 123a.

[0064] [2-2. Operation] The airflows AF1, AF2, and AF3, and the negative pressure region S1 that are generated when the operation of the blower 160 is started are the same as those in the first embodiment, and therefore detailed description thereof will be omitted.

[0065] [2-3. Effects, etc.] As a modified example, the blower device 100 may include a filter for collecting dust contained in the air drawn into the air inlet 112.

[0066] This allows purified air (airflow AF1) with less dust than before passing through the filter to be blown out from outlet opening 134. Therefore, a comfortable air environment can be provided for the user using blower device 100.

[0067] As described above, the first embodiment and the modified examples have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can also be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. Furthermore, it is also possible to combine the components described in the first embodiment and the modified examples to create new embodiments.

[0068] It should be noted that the above-described embodiments and modifications are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalents.
