[0001] The present invention relates to a humidifier. [Background technology]

[0002] A conventional structure for blowing air into a room from a ceiling is disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-249181 Summary of the Invention [Problem to be solved by the invention]

[0004] There are humidifiers that are installed on the ceiling, that draw in indoor air from below the humidifier, and then blow the humidified air back out into the room below. In such humidifiers, the air inlet that draws in air from the room and the air outlet that blows the humidified air into the room are close to each other, so there is a possibility that the humidified air blown out from the air outlet will short-circuit to the air inlet.

[0005] Therefore, an object of the present invention is to provide a humidifier that can prevent the blown-out air from being sucked into the intake port when sucking in air from below and blowing the humidified air downward again. [Means for solving the problem]

[0006] To achieve the above object, one aspect of the present invention provides a humidifier comprising: a box-shaped housing having a bottom surface with an inlet and an outlet, a top surface opposite the bottom surface, and a plurality of side surfaces connected to the bottom and top surface; a liquid atomization device that humidifies air drawn into the housing; and a plate-shaped panel portion positioned vertically below the housing and facing the bottom surface. The housing has a shielding wall that extends vertically downward from the bottom surface and whose tip abuts against the panel portion. The shielding wall is positioned between the inlet and the outlet and prevents humidified air blown out from the outlet from being drawn into the inlet. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a humidifier that can prevent the blown-out air from being sucked into the air inlet when sucking in air from below and blowing the humidified air downward again. [Brief explanation of the drawings]

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following embodiments are examples of the present invention and do not limit the technical scope of the present invention. Furthermore, the same components are designated by the same reference numerals throughout the drawings, and their description will be omitted. Furthermore, in each drawing, detailed descriptions of components not directly related to the present invention will be omitted.

[0010] The schematic configuration of a humidifier 1 according to one embodiment of the present invention will be described with reference to Figs. 1 to 3. Fig. 1(a) is a perspective view of the humidifier 1 viewed from above, and Fig. 1(b) is an enlarged view of a portion of the bottom surface 2 and panel portion 6 in Fig. 1(a). Fig. 2(a) is a side view of the humidifier 1 viewed from the air inlet 11 side, and Fig. 2(b) is a side view of the humidifier 1 viewed from one side surface 4a. Fig. 3(a) is a bottom view of the humidifier 1 viewed from vertically below with the panel portion 6 removed, and Fig. 3(b) is a view of the humidifier 1 viewed from diagonally below with the panel portion 6 removed.

[0011] The humidifier 1 is a device that humidifies a target space by drawing in air from within the target room, humidifying the air, and then blowing it out into the room. The humidifier 1 is fixed to the ceiling of the target room. For example, the humidifier 1 is installed so that it is embedded in the ceiling with a portion of the bottom surface 2 (described below) exposed to the room. The humidifier 1 comprises a housing 5, a panel unit 6, an air intake fan 34 (see FIG. 5), and a liquid atomization device 33 (see FIG. 5). Details of the air intake fan 34 and the liquid atomization device 33 will be described later.

[0012] The housing 5 is the outer shell of the humidifier 1, which is configured in the shape of a hollow box. An air intake fan 34 and a liquid atomization device 33 are arranged inside the housing 5. The housing 5 includes a bottom surface 2, a top surface 3, a side surface 4, a filter 35, an intake port 11, an intake air duct 41, an outlet port 12, a shielding wall 13, a panel support portion 14, a fastening wall 15, a maintenance portion 17, and a locking portion 21.

[0013] The bottom surface 2 is one surface that constitutes the box shape of the housing 5, and is provided in the shape of a rectangular plate.

[0014] The top surface 3 is a surface facing the bottom surface 2 and is provided in the shape of a rectangular plate that is smaller than the bottom surface 2.

[0015] The side surface 4 is a surface connecting the bottom surface 2 and the top surface 3, and a plurality of rectangular plate-shaped surfaces are provided. In this embodiment, four side surfaces 4 are provided. Hereinafter, one of the four side surfaces 4 will be referred to as one side surface 4a, and the surface opposing one side surface 4a will be referred to as the opposing surface 4b. Of the remaining two side surfaces, the side facing the suction port 11 described below will be referred to as the suction port-side side surface 4c, and the side facing the outlet 11 described below will be referred to as the outlet-side side surface 4d.

[0016] In this embodiment, the bottom surface 2 is rectangular and larger than the top surface 3, and extends outward beyond the side surface 4. Hereinafter, the portion of the bottom surface 2 that is inside the side surface 4 will be referred to as an inner periphery 2a, and the portion that is outside the side surface 4 will be referred to as a flange portion 2b.

[0017] The filter 35 is a member that purifies the air drawn into the housing. The filter 35 is provided on the side surface 4c on the inlet side. The filter 35 is, for example, a HEPA filter, and captures 99.97% or more of particles with a particle size of 0.3 μm.

[0018] Suction port 11 is a rectangular opening provided in flange portion 2b and located near suction port side surface 4c. In other words, suction port 11 is located on bottom surface 2 outside suction port side surface 4c.

[0019] Intake air passage 41 is an air passage that guides indoor air sucked in through inlet 11 into the inside of housing 5. Intake air passage 41 communicates between inlet 11 provided in flange portion 2b and filter 35 provided on inlet-side side surface 4c.

[0020] The air outlets 12 are openings that blow out humidified air, which is air that has been humidified inside the housing, and two are provided in a rectangular shape on the inner circumferential portion 2a. Here, the inner circumferential portion 2a is the portion of the bottom surface 2 that is more inward than the side surface 4. Therefore, the two air outlets 12 are located more inward than the one side surface 4a, the opposing surface 4b, the inlet-side side surface 4c, and the air outlet-side side surface 4d on the bottom surface 2. Here, as shown in FIG. 3(b), one of the two air outlets 12 is located near the one side surface 4a, and the other is located near the opposing surface 4b.

[0021] Shielding wall 13 is a wall for preventing the humidified air blown out from outlet 12 from short-circuiting to inlet 11. In other words, shielding wall 13 is a member located between inlet 11 and outlet 12, and prevents the humidified air blown out from outlet 12 from being sucked into inlet 11. In this embodiment, the shielding wall 13 is located on the same plane as the suction port side surface 4c, and extends vertically downward from the bottom surface 2. As shown in FIG. 2(a), the tip of the extension of the shielding wall 13 abuts against the panel portion 6. Furthermore, one longitudinal end of the shielding wall 13 is located on approximately the same plane as one side surface 4a, and the other longitudinal end of the shielding wall 13 is located on approximately the same plane as the opposing surface 4b.

[0022] Here, air inlet 11 is located on flange portion 2b, air outlet 12 is located on inner periphery 2a, and shielding wall 13 is located on the same plane as air inlet-side side surface 4c, which is the boundary between flange portion 2b and inner periphery 2a. In other words, shielding wall 13 is located between air inlet 11 and air outlet 12 on bottom surface 2, thereby separating air inlet 11 and air outlet 12. With this configuration, the humidified air blown out from air outlet 12 is blocked by shielding wall 13, thereby preventing short-circuiting to air inlet 11.

[0023] It should be noted that the longitudinal end of shielding wall 13 does not need to be completely flush with one side surface 4a and the opposing surface 4b. For example, a state in which one longitudinal end is located outside one side surface 4a or a state in which the other longitudinal end is located outside the opposing surface 4b are also included in the definition of being substantially flush. It is sufficient that the length of shielding wall 13 is at least the length connecting one side surface 4a and the opposing surface 4b, and that the humidified air blown out from air outlet 12 is prevented from short-circuiting to air inlet 11.

[0024] In this embodiment, the shielding wall 13 is located on the same plane as the suction port-side side surface 4c, but is not limited to this. The shielding wall 13 may be provided in any manner as long as the suction port 11 and the air outlet 12 are separated by the shielding wall 13.

[0025] The panel support portion 14 is a member that rotatably supports the panel portion 6. The panel support portion 14 protrudes vertically downward from the flange portion 2b of the bottom surface 2, and the tip of the protrusion bends upward, forming a substantially U-shape in a side view from one side surface 4a. One panel support portion 14 is provided at each of the four corners of the rectangular shape of the bottom surface 2. Hereinafter, of the panel support portions 14, the one provided near the inlet-side side surface 4c will be referred to as the inlet-side panel support portion 14a, and the one provided near the outlet-side side surface 4d will be referred to as the outlet-side panel support portion 14b. The tip of the protrusion of the inlet-side panel support portion 14a bends in a direction away from the inlet-side side surface 4c. The tip of the protrusion of the outlet-side panel support portion 14b bends in a direction away from the outlet-side side surface 4d.

[0026] The fastening wall 15 is a wall for fixing the panel part 6 to the housing 5 so that it does not rotate. A pair of fastening walls 15 are provided on the side of the bottom surface 4a and the side of the opposing surface 4b. In this embodiment, one of the fastening walls 15 is located on the same plane as one side surface 4a, and the other is located on the same plane as the opposing surface 4b. In other words, the pair of fastening walls 15 face each other. The fastening wall 15 extends vertically downward from the bottom surface 2, and the tip of the extension abuts against the panel portion 6. A circular hole is provided in the center of the fastening wall 15 for fastening the panel portion 6 to the housing 5. The engagement between the housing 5 and the panel portion 6 will be described in detail later. The fastening wall 15 has a ventilation opening 16.

[0027] The ventilation openings 16 are rectangular openings provided in the fastening walls 15, and in this embodiment, two are provided in each of the pair of fastening walls 15. Providing the ventilation openings 16 in the fastening walls 15 makes it possible to blow out humidified air from the one side surface 4a side and the opposing surface 4b side, making it easier to diffuse the humidified air into the room.

[0028] The maintenance section 17 is an openable and closable rectangular opening provided on the inner circumferential portion 2a of the bottom surface 2. The maintenance section 17 is located vertically below the air supply fan 34 described below, and is located near the shielding wall 13 on the bottom surface 2.

[0029] The locking portions 21 are members for fixing the humidifier 1 to the ceiling and are locked to hanging bolts suspended from a position higher than the ceiling. The locking portions 21 are attached at two locations each on the inlet side surface 4c and the outlet side surface 4d.

[0030] The panel portion 6 is a member for rectifying the flow of humidified air blown vertically downward from the air outlets 12 in a horizontal direction along the ceiling. The panel portion 6 is formed in the shape of a rectangular plate facing the bottom surface 2, and is located vertically below the bottom surface 2. The panel portion 6 is large enough to cover at least both of the air outlets 12. With this configuration, the air blown vertically downward from the air outlets 12 can be reliably rectified in the horizontal direction.

[0031] The panel unit 6 may be attached in two pieces. In this embodiment, the panel unit 6 is attached in two pieces. Hereinafter, the panel unit 6 located vertically below the air inlet 11 and the maintenance unit 17 is referred to as the air inlet-side panel unit 6a, and the panel unit 6 located vertically below the air outlet 12 is referred to as the air outlet-side panel unit 6b. Dividing the panel unit 6 into two pieces improves maintainability. For example, to access the maintenance unit 17, only the air inlet-side panel unit 6a needs to be removed. This reduces the weight by half compared to attaching and detaching a single panel unit 6, thereby reducing the burden on the worker. Furthermore, soundproofing material may be provided on the surface of the panel unit 6 facing the bottom surface 2, which faces the housing. Providing soundproofing material can prevent sound generated inside the housing from propagating to the interior of the room. The panel unit 6 includes a panel rotation shaft 7 and a fastening unit 8.

[0032] The panel rotation shafts 7 are rotation shafts for rotatably engaging the panel unit 6 with the panel support members 14. The panel rotation shafts 7 are cylindrical and provided at two adjacent corners of the four rectangular corners of the panel unit 6. In this embodiment, the panel unit 6 is divided into two parts, so that the inlet-side panel unit 6a is provided with two panel rotation shafts 7 corresponding to the inlet-side panel support members 14a, and the outlet-side panel unit 6b is provided with two panel rotation shafts 7 corresponding to the outlet-side panel support members 14b. The panel rotation shafts 7 may be provided in any manner as long as they can rotatably engage with the panel support members 14 provided on the housing 5. For example, one side of the rectangular shape of the panel unit 6 may be machined into a cylindrical shape to form one panel rotation shaft 7 that can simultaneously engage with two panel support members 14.

[0033] The fastening portion 8 is a member for fixing the panel portion 6 to the housing 5 so that it does not rotate. The fastening portion 8 extends from the panel portion 6 toward the bottom surface 2 side and is provided in the shape of a plate parallel to the fastening wall 15. The fastening portion 8 is provided at one of the four corners of the rectangular shape of the panel portion 6, which is different from the corner where the panel rotation axis 7 is provided. One fastening wall 15 is provided at each of the two opposite corners. In other words, a pair of fastening walls 15 are provided on the panel portion 6, and the fastening walls 15 face each other. The fastening portion 8 abuts against the outer surfaces of the fastening walls 15 when the panel portion 6 is fixed to the housing 5 (when the panel portion 6 is parallel to the bottom surface 2).

[0034] Here, the engagement between the housing 5 and the panel section 6 will be described with reference to Figure 4. Figure 4 is a schematic diagram showing the movement when attaching the panel section 6 to the housing 5. While the case of attaching the inlet-side panel section 6a will be described as a representative example, the same procedure can be used when attaching the outlet-side panel section 6b. Figure 4(a) shows the movement of engaging the panel rotation shaft 7 with the inlet-side panel support section 14a. Also, Figure 4(b) shows the procedure for fixing the inlet-side panel section 6a to the housing 5 so that it does not rotate.

[0035] First, with the portion of the suction port side panel 6a where the panel rotation shaft 7 is located facing up, the suction port side panel 6a is lifted from diagonally below the housing 5 to engage the panel rotation shaft 7 with the suction port side panel support part 14a (see Figure 4(a)). Because the suction port side panel support part 14a is roughly U-shaped and the panel rotation shaft 7 is cylindrical, the engaged suction port side panel 6a is rotatably supported by the housing 5.

[0036] Next, rotate suction port side panel 6a toward bottom surface 2 so that bottom surface 2 and suction port side panel 6a are parallel (see FIG. 4(b)). At this time, shielding wall 13 and fastening wall 15 abut against suction port side panel 6a, separating suction port 11 and air outlet 12. Fastening portion 8 abuts against the outer surface of fastening wall 15, and the circular hole provided in fastening portion 8 and the circular hole provided in fastening wall 15 overlap.

[0037] Next, fastening portion 8 and fastening wall 15 are fastened with screws or the like to fix suction port side panel portion 6a and housing 5 so that they do not rotate. This procedure makes it possible to easily attach panel portion 6 to housing 5.

[0038] Next, the internal configuration of the humidifier 1 will be described with reference to Fig. 5. Fig. 5(a) is a cross-sectional view taken along line AA in Fig. 3(a), and Fig. 5(b) is a cross-sectional view taken along line BB in Fig. 3(a).

[0039] The housing 5 has therein an air supply space 32, a humidification space 31, and an outlet air passage 40. The air supply space 32 and the humidification space 31 communicate with each other to allow ventilation.

[0040] The air supply space 32 is a space for blowing air that has flowed into the inside of the housing 5 through a filter 35 to the humidifying space 31. In the air supply space 32, an air supply fan 34 is arranged.

[0041] The air supply fan 34 is a fan that guides air drawn into the air supply space 32 from the air intake port 11 to the humidification space 31. The air supply fan 34 is located vertically above the maintenance unit 17. The air supply fan 34 may be, for example, a sirocco fan.

[0042] The humidifying space 31 is a space for humidifying the air drawn into the housing 5. In the humidifying space 31, a liquid atomization device 33 is disposed.

[0043] The liquid atomization device 33 is a device for humidifying the air in the humidification space 31. The liquid atomization device 33 includes a water storage section 33a, a water lifting pipe 33b, and a collision wall 33c.

[0044] The water reservoir 33a is formed in a mortar shape and stores water supplied from the outside. The water reservoir 33a is provided below the liquid atomization device 33.

[0045] The lift pipe 33b has a hollow conical shape and is open at the tip of the cone that faces the bottom surface of the water storage section 33a. The lift pipe 33b is connected to a rotary motor (not shown), and as the lift pipe 33b rotates, centrifugal force causes the water stored in the water storage section 33a to rotate along the inner wall surface of the lift pipe 33b and is pumped from the lower end to the upper end. An opening is provided in the wall surface at the upper end of the lift pipe 33b, and the pumped water is released as water droplets from the opening in the wall surface by centrifugal force caused by the rotation.

[0046] The collision wall 33c is a wall that annularly surrounds the water rise pipe 33b. When the water droplets discharged from the water rise pipe 33b collide with the collision wall 33c, the water droplets can be further broken down into finer droplets.

[0047] By atomizing the water droplets in this way, the liquid atomization device 33 humidifies the air in the humidification space 31.

[0048] The outlet air duct 40 is an air duct that connects the humidification space 31 and the air outlet 12, and guides humidified air, which is air humidified in the humidification space 31, into the room. The outlet air duct 40 is an S-shaped meandering air duct that reduces the wind speed so that the humidified air does not flow forcefully into the room. The humidified air that has passed through the outlet air duct 40 is blown out vertically downward from the air outlet 12, and upon impacting with the panel portion 6, the air flows horizontally along the ceiling and is blown out into the room. In this embodiment, two air outlets 12 are provided on the bottom surface 2, and therefore two outlet air ducts 40 are also provided.

[0049] As shown in FIG. 5(a), the air inlet 11 and the air outlet 12 are separated by a shielding wall 13. A ventilation opening 16 is provided in the fastening wall 15. Therefore, the humidified air blown out from the air outlet 12 is rectified horizontally by the panel portion 6 and blown out in the directions of the three sides excluding the direction of the air outlet-side side surface 4c. This configuration makes it possible to diffuse the humidified air into the room while suppressing short-circuiting from the air outlet 12 to the air inlet 11. In other words, when the air inlet 11 draws in air from below and the air outlet 12 blows out the humidified air downward again, it is possible to prevent the air blown out from the air outlet 12 from being sucked into the air inlet 11. (Summary of the Invention) The humidifier of the present invention comprises a box-shaped housing 5 formed with a bottom surface 2 having an intake port 11 and an exhaust port 12, a top surface 3 opposite the bottom surface 2, and a plurality of side surfaces 4 connected to the bottom surface 2 and the top surface 3, a liquid atomization device 33 that humidifies air sucked into the housing 5, and a plate-shaped panel portion 6 located vertically below the housing 5 and facing the bottom surface 2, the housing 5 having a shielding wall 13 extending vertically downward from the bottom surface 2 with the tip of said extension abutting the panel portion 6, the shielding wall 13 being located between the intake port 11 and the exhaust port 12 and preventing the humidified air blown out from the exhaust port 12 from being sucked into the intake port 11.

[0050] With this configuration, air inlet 11 and air outlet 12 are separated by shielding wall 13, which makes it possible to prevent humidified air blown out from air outlet 12 from short-circuiting to air inlet 11. In other words, when air inlet 11 draws in air from below and air outlet 12 blows out the humidified air downward again, it is possible to prevent the air blown out from air outlet 12 from being drawn into air inlet 11.

[0051] In addition, the shielding wall 13 may be configured so that one end in the longitudinal direction perpendicular to the vertical downward direction is located on approximately the same plane as one side surface 4a, which is one of the multiple side surfaces 4, and the other end in the longitudinal direction is located on approximately the same plane as the opposing surface 4b opposite the one side surface 4a.

[0052] According to this configuration, the shielding wall 13 has a length that connects at least one side surface 4a and the opposing surface 4b, so that the air inlet 11 and the air outlet 12 can be separated reliably.

[0053] In addition, two air outlets 12 may be provided on the bottom surface 2, one located on one side surface 4a and the other located on the opposing surface 4b, and the panel portion may be configured to be located vertically below at least one air outlet 12 and the other air outlet 12.

[0054] With this configuration, the air blown vertically downward from the two air outlets 12 can be reliably collided with the panel portion 6 and rectified in the horizontal direction. In addition, one of the air outlets 12 is located on one side 4a and the other on the opposite side 4b, so the humidified air can be diffused into the room in a balanced manner.

[0055] In addition, the housing 5 may be configured to have a panel support portion 14 that is approximately U-shaped and protrudes vertically downward from the bottom surface 2, with the tip of the protrusion bent upward, and the panel portion 6 may be configured to have a panel rotation axis 7 that engages with the panel support portion 14 and rotatably fixes the panel portion 6 to the housing 5.

[0056] With this configuration, the panel unit 6 can be easily attached to the housing 5.

[0057] The panel section 6 may also be configured to include a housing-facing surface that faces the bottom surface 2 of the housing 5, and a soundproofing material provided on the housing-facing surface.

[0058] According to this configuration, sound generated inside the housing 5 is received by the panel portion 6, and therefore, the sound can be prevented from propagating into the room.

[0059] The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and it can be easily inferred that various improvements and modifications are possible within the scope of the invention without departing from the spirit of the invention.

[0060] In the humidifier 1 according to the present embodiment, the water atomized by the liquid atomization device 33 is sprayed out, but this is not limited to this. For example, hypochlorous acid water may be atomized and sprayed out by the liquid atomization device 33. In this way, it is possible to enjoy the effect of suppressing shortcuts even when the humidifier is functioning to purify the space by purifying the air in the room. [Industrial Applicability]

[0061] The humidifier according to the present invention is useful as a ceiling-embedded humidifier for humidifying a room. [Explanation of symbols]
