  Hereinafter, a deodorizing apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an appearance of a deodorizing apparatus 1 according to an embodiment of the present invention. The deodorizing apparatus 1 includes a deodorizing apparatus main body 10 having an operation panel 40 disposed on an upper surface, a first suction arm 11 and a second extending from the deodorizing apparatus main body 10. And a suction arm 12.

  The deodorizing device main body 10 houses and holds the devices constituting the deodorizing device 1 and also includes a first suction arm 11 and a second suction arm 12 (hereinafter referred to as a first suction arm) extending from the deodorizing device main body 10. 11 and the second suction arm 12 are collectively referred to as a suction arm.), The root portion of the first suction arm 11 is supported. In the present embodiment, the first suction arm 11 and the second suction arm 12 have a cylindrical shape with a rectangular cross section formed by bending and forming stainless steel, and can be bent and extended via a rotating joint. Consists of. Inside the arm is an odor vent. Casters 13 are attached to the four corners of the lower surface of the deodorizing apparatus main body 10, and a handle 14 is attached to the upper side of the deodorizing apparatus main body 10. Thereby, nurses, helpers and the like (hereinafter referred to as workers) can move the deodorizing apparatus 1 by hand to the bedside to be used. In addition, the stopper 13a is attached to some casters 13, and the deodorizing apparatus 1 can be reliably stopped and held by locking the casters 13 with the stopper 13a. Further, a lattice-shaped hanger surface (not shown) is formed on the side surface of the deodorizing apparatus main body 10, and a plurality of storage rods 15 having different sizes are detachably attached to the hanger surface. These storage baskets 15 can separately store unused diapers, towels and other equipment, used diapers, and the like. A storage lid 15 for storing used diapers and the like is provided with a sealing lid 15a. Thereby, it is possible to prevent the odor in the storage bowl 15 from leaking to the outside.

  An operation panel 40 is provided on the upper surface of the deodorizing apparatus 1. The operation panel 40 is composed of a switch group for an operator to operate the deodorizing apparatus 1. As will be described later, the operation of raising and lowering the suction arms 11 and 12 and turning on / off the odor suction operation by the switch group. An OFF operation can be executed.

  2 is a partial side view showing each part of the suction arms 11 and 12 in an enlarged manner. 2 (a-1) and 2 (a-2) show the tip of the second suction arm 12, as shown in both figures, the bottom surface near the tip of the second suction arm 12 has an odor. An opening 12c having a diameter of 160 mm for taking in is formed, and a frustoconical odor suction cover 18 is attached so as to surround the opening 12c. The odor suction cover 18 faces the odor generation source, forms a taper angle θ, is supported at the outer peripheral edge position of the opening 12c, and is expanded in diameter toward the odor suction port 18a at the opening end. Thus, the odor suction port 18a is directed to the odor generation source, whereby the odor is reliably sucked and sucked into the opening 12c through the cover inner space 18b surrounded by the odor suction cover 18, and the odor is not released to the outside. The taper angle θ of the odor suction cover 18 of this embodiment is set to θ = 60 °, but the range of the taper angle θ can be set to about θ = 45 to 65 °. The odor suction cover 18 is made of, for example, a transparent resin material such as an acrylic plate, so that the diaper replacement work or the like is hindered even when the odor suction port 18a at the open end is brought close to the odor source. It does not occur.

  As shown in FIG. 2 (a-1), the inside of the odor suction cover 18 covers the opening 12c formed in the second suction arm 12, and secures a predetermined distance h from the opening. A slightly smaller flat shield plate 19 is attached. By disposing the shielding plate 19 on the front surface of the opening, a gap 18c as a suction ventilation portion is formed between the second suction arm 12 and the shielding plate 19, and odor is sucked from the gap 18c (FIG. By indicating the flow of odor with a middle arrow), the wind speed of the odor to be sucked is increased, and the odor of a predetermined air volume can be sucked into the apparatus main body more effectively.

  FIG. 2A-2 shows an example in which the shielding plate 19 has a flat conical shape that protrudes downward. By forming an odor flow along the surface of the shielding plate 19 during odor suction, more effective suction is possible.

  Hereinafter, with reference to FIGS. 2B and 2C, the flow of odor from the tip of the second suction arm 12 to the inside of the deodorizing apparatus main body 10 (FIG. 1) at the root of the first suction arm 11, Briefly described. As shown in FIG. 2B, the air passages 11a and 12a formed in the first suction arm 11 and the second suction arm 12 are connected to the rotary joint 17 to which a ring-shaped seal joint 17a is attached. It communicates with. Further, as shown in FIG. 2 (c), the first suction arm 11 has a telescopic duct 20 extending from the deodorizing apparatus main body 10 (FIG. 1) via the rotation support portion 16 at the base portion thereof. Is supported rotatably via a seal joint 16a. Thus, the 2nd suction arm 12 is connected with the tip of the 1st suction arm 11 via the seal joint 17a so that rotation is possible. Also, the odor sucked from the odor suction port 18a is vented from the second suction arm 12 into the first suction arm 11 and guided to the inside of the deodorizing apparatus main body 10 (FIG. 1).

Here, another embodiment of the odor suction cover 18 and the shielding plate 19 at the tip of the second suction arm 12 will be described with reference to FIGS.
3A and 3B show examples in which the taper angle of the odor suction cover 18 shown in FIG. 2A-1 is set to θ = 45 ° and 65 ° as described above. In the embodiment shown in FIG. 3A, the taper angle (θ = 45 °) of the odor suction cover 18 is used, but in this case, the height H of the odor suction cover 18 is set in the case of FIG. Can be made lower and closer to the subject. At this time, the diameter of the open end of the suction cover 18 can be increased, and the suction range can be widened. Moreover, the attachment position of the shielding plate 19 can reduce the distance h of the gap 18c from the opening 12c, thereby increasing the wind speed of the sucked odor and ensuring a sufficient air volume (intake volume). FIG. 3B shows another embodiment in which the odor suction cover 18 has a taper angle (θ = 45 °). In this embodiment, the height H of the odor suction cover 18 is higher than in the case of FIG. 2 (a-1) and the suction target range is narrowed, but the attachment position of the shielding plate 19 can increase the distance h from the opening 12c. Sufficient suction air volume can be secured.

  FIGS. 3C to 3F show various shapes of shielding plates 19 as modifications of FIG. 2A-2. FIG. 3C shows the height of the downward-facing flat conical shielding plate 19 shown in FIG. 2A-2 up to the open end of the odor suction cover 18 and is surrounded by the odor suction cover 18 and the shielding plate 19. This is a modification in which the volume of the cover inner space 18b is reduced to increase the wind speed during odor suction. FIG. 3D shows a modification in which the shielding plate 19 has a truncated cone shape whose bottom surface is a disk shape. In this case, the volume of the cover inner space 18b surrounded by the odor suction cover 18 and the shielding plate 19 can be further reduced, and the odor suction effect can be further enhanced.

  FIGS. 3E and 3F show an example in which a curved plate that is convex downward is adopted as a modification of the shielding plate 19. In this case, since there is no sharp portion, it is possible to ensure a smooth flow of odor in the cover inner space 18b and to improve safety when using the device. In the case of FIG. 3 (e), a suction effect close to that of FIG. 2 (a-2) is expected, but the odor sucked along the odor suction cover 18 is sucked along the shielding plate 19. Since the effect that the odor is smoothly mixed in the cover inner space 18b can be expected, the turbulent flow state generated in the vicinity of the gap 18c can be suppressed. The curved surface shape of the shielding plate 19 is not limited to a spherical surface, and any convex curved plate can be adopted. The mounting height h (see FIG. 3A) can be set as appropriate depending on the height of the shielding plate 19 at that time.

  Next, the structure of each apparatus accommodated in the deodorizing apparatus main body 10 and the processing method of the sucked odor will be described.

  FIG. 4 is a side sectional view of the deodorizing apparatus 1 indicated by a sectional line III-III in FIG. For simplification of the drawings, the lifting mechanism that lifts and lowers the suction arm 11 in the vertical direction is not shown.

  As shown in FIG. 4, in the deodorizing apparatus main body 10, the telescopic duct 20 connected to the air passage 11a of the first suction arm 11 and the telescopic duct 20 are connected to the odor suction port 18a (FIG. 1). ), An activated carbon cartridge 22 filled with activated carbon that adsorbs odor components together with a filter that captures dust and the like in the odor, and a battery 23 that supplies power to the intake fan 21. Is provided. In the figure, the flow of the sucked odor is schematically shown by arrows.

  The telescopic duct 20 serves as a ventilation path through which odors flowing from the ventilation path 11a of the first suction arm 11 are vented. The telescopic duct 20 is a hose that expands and contracts following the lifting and lowering operation of the first suction arm 11 that occurs when the suction arm 11 is adjusted in the height direction, as will be described later, such as a bellows type resin hose. It is configured.

  The intake fan 21 is supplied with electric power from the battery 23, rotates the sirocco fan 21b with the motor 21a, and rotates and sucks the sirocco fan 21b from the odor suction port 18a (FIG. 1) via the suction arms 11 and 12. The odor is sucked and odor can be sent from the exhaust side. As the suction performance of the intake fan 21, in this embodiment, the two intake fans 21 face each other across the air passage 20a so that the odor intake amount can be secured at about 3000 l / min at the odor suction port 18a (FIG. 1). Are arranged. The odor intake amount 3000 l / min at the odor suction port 18 a is a value obtained by verification through experiments, and it was confirmed that the diffusion of odor could be prevented if this intake amount was ensured. The odor sucked by the intake fan 21 is sent to the deodorization buffer unit 24.

  The deodorization buffer unit 24 is a space formed to allow the odor sent by the intake fan 21 to uniformly pass through the activated carbon cartridge 22 and to ensure a predetermined wind speed and intake amount at the odor suction port 18a. For example, in the present embodiment, the height H of the deodorization buffer unit 24 is set to 96 mm. In addition, by setting the height H of the deodorization buffer unit 24 to about 100 mm, it is possible to allow the odor to pass through the activated carbon cartridge 22 uniformly and to secure a predetermined intake amount at the odor suction port 18a.

  The activated carbon cartridge 22 is detachably attached to a lower position in the deodorizing apparatus main body 10, captures fine particles, dust and the like in the passing odor, and adsorbs and deodorizes odor components by mesopore-based activated carbon. Here, the details of the activated carbon cartridge 22 will be described with reference to FIG. 5A and 5B are views showing the activated carbon cartridge 22, wherein FIG. 5A is a top view of the activated carbon cartridge 22, and FIG. 5B is a cross-sectional view of the activated carbon cartridge 22 shown by arrows bb in FIG. .

As shown in FIG. 5 (a), the activated carbon cartridge 22 has an outer shell formed by a lattice frame-shaped storage case 25 in which an opening 25a is formed. Inside the housing case 25, a nonwoven fabric filter 26 is disposed on the upper and lower surfaces and a central partition in the thickness direction, and an activated carbon layer 27 filled with mesopore-based activated carbon is formed therein. As the non-woven fabric filter 26, for example, a Filedon filter (registered trademark) is used, and in order to stably fill the mesopore-based activated carbon into the housing case 25, and as a prefilter, fine particles and dust in the sucked odor are used. Play a role to capture. The activated carbon layer 27 adsorbs odor components in odor. The mesopore-based activated carbon used is a wood-based substantially spherical activated carbon (about 3 to 5 mm), the diameter of the main pore (mesopore) formed in the activated carbon is 2 to 50 nm, and the specific surface area is 1000 to 1400 m ² / g. Consists of degree.

  The mesopore-based activated carbon preferably has a mesopore volume ratio of about 55 to 70% of the total activated carbon adsorption volume in consideration of the air permeability and deodorizing effect of the activated carbon layer 27. More preferably, it is confirmed that 60 to 65% is preferable as an experimental result in terms of the deodorizing effect. Conventional activated carbon has mainly been used with micropores (0.8 to 2 mm) formed, but the type mainly composed of activated carbon with mesopores as in this embodiment is preferred. It was confirmed by experiment that it was excellent in the deodorizing effect of the filth compound odor. Moreover, clean air can be discharged from the activated carbon cartridge 22 by mixing an antibacterial substance such as coral sand into the activated carbon layer 27. Moreover, in this embodiment, since it is set as the structure which accommodates the nonwoven fabric filter 26 and the activated carbon layer 27 in the storage case 25, it is preferable to replace | exchange the activated carbon cartridge 22 for a new thing as it is, and to replace | exchange at the utilization site of the deodorizing apparatus 1. However, since the nonwoven fabric filter 26 is a product that can be reused if it is washed, it is also preferable to use a recycling cartridge that replaces the activated carbon layer 27 and reuses the storage case.

  The odor that has passed through the activated carbon cartridge 22 from the deodorizing buffer unit 24 is deodorized and cleaned, and is discharged from the lower surface of the deodorizing apparatus main body 10. That is, the lower surface of the deodorizing apparatus body 10 is an air outlet.

  As described above, when the two intake fans 21 disposed opposite to each other so as to sandwich the air passage in the deodorizing apparatus 1 are operated, the odor sucked from the odor suction port 18a is converted into the second suction arm. The ventilation path 11 a of the first suction arm 11 is ventilated from the 12 ventilation paths 12 a, and a planar flow state is established in the deodorization buffer unit 24 in the deodorization apparatus 1, and is led to the activated carbon cartridge 22.

  When the odor generated from the odor source is sucked, the odor suction port 18a located at the tip of the second suction arm 12 is moved as close as possible to the upper position as close as possible to the odor source. By doing so, it is preferable to prevent the odor from diffusing around the deodorizing apparatus 1. In the deodorizing apparatus 1 of the present embodiment, the first suction arm 11 and the second suction arm attached to the upper surface of the deodorizing apparatus main body 10 so that the odor suction port 18a can be positioned in the vicinity of the odor generating source. 12 is rotated around the rotation support portion 16 and the rotation joint 17 by a predetermined angle and extended, thereby performing planar alignment between the odor generation source and the odor suction port 18a. In addition to this, the deodorizing apparatus 1 includes an elevating device 30 that adjusts the height positions of the suction arms 11 and 12 so that the odor suction port 18a has a predetermined height.

  FIG. 6 is a plan view of the deodorizing apparatus 1 as viewed from above. As shown in the drawing, the first suction arm 11 can be rotated clockwise and counterclockwise around the rotation support portion 16 in a plan view, and the second suction arm 12 is similar around the rotation joint 17. Can be rotated. As a result, the operator can handle the handle 12b attached to the tip of the second suction arm 12 in the range from when the suction arms 11 and 12 are folded to when they are fully extended. One suction arm 11 can be linked to move the odor suction port 18a at the tip of the second suction arm 12 to a desired position (such as an odor generation source). Further, since the first suction arm 11 and the second suction arm 12 can be freely moved in this way, the first suction arm 11 is used when the deodorizing apparatus 1 is on standby or moved by hand. And the second suction arm 12 are preferably folded so as to overlap each other.

  FIG. 7 shows a side sectional view of the deodorizing apparatus 1. As shown in the figure, the deodorizing apparatus 1 is provided with a lifting device 30 that lifts and lowers the first suction arm 11 and the second suction arm 12 in the vertical direction. This elevating device 30 is arranged in the vertical direction with a gear motor M, a transmission belt 31 (not shown) spanned on the rotating shaft of the gear motor M, and upper and lower ends are supported by a support plate (not shown), A ball screw 32 that can be rotated by the driving force of the belt 31, a base plate 35 to which a nut 36 screwed into the ball screw 32 is fixed, and standing at four corners of the base plate 35, and an upper surface fixed to the arm support plate 38.

In the drawing, in order to explain the configuration and operation of the elevating frame 37, a part of the telescopic duct 20 and the intake fan 21 are not shown.

  Hereinafter, the configuration and operation of the lifting device 30 will be described. An arm support plate 38 constituting the upper surface of the elevating frame 37 is connected to the first suction arm 11 via the rotation support portion 16. A nut 36 attached to the base plate 35 constituting the lower surface is screwed with the ball screw 32. A pulley (not shown) is provided at the end of the ball screw 32, and the transmission belt 31 is stretched between this pulley and a pulley (not shown) provided on the gear motor M, whereby the gear motor M is driven to rotate. Is transmitted to the ball screw 32. The gear motor M is a variable speed motor, and by operating a switch (FIG. 1) of the operation panel 40 provided on the upper surface of the deodorizing apparatus body 10, the gear motor M can be set to a desired rotation direction and rotation speed. it can. At this time, since the four shafts 33 are held in the standing position by the linear bushing 34, the lifting frame 37 moves up and down depending on the rotation direction of the motor in a state where the rotation is suppressed. be able to. The suction arms 11 and 12 move up and down together with the lift frame 37. In the present embodiment, the maximum stroke S of the elevating frame 37 is set to 360 mm. The operator can adjust the height of the odor suction port 18 a formed at the tip of the second suction arm 12 within this range by operating the operation panel 40.

  Next, the usage method of the deodorizing apparatus 1 which concerns on embodiment of this application is demonstrated.
