JP7397046B2 - Arrangement structure for arranging chamber boxes and objects to be accommodated - Google Patents

Description

The present invention relates to a chamber box capable of accommodating objects to be accommodated, such as air purifying units, and an arrangement structure for arranging objects to be accommodated.

Air discharged from the air conditioner flows through the duct and is supplied to living spaces and the like. Generally, the flow rate of air flowing within the duct is large in order to quickly change the temperature of the living space. Furthermore, the flow rate fluctuates greatly depending on the set temperature and the like. For this reason, an object to be accommodated, such as an air purifier installed in a duct, may vibrate greatly within the duct due to the application of the wind force of the flowing air.

For example, there are support members that fix the accommodated object using anti-vibration hardware or the like (see, for example, Patent Document 1), and support members that support the object with a bracket or the like (see, for example, Patent Document 2).

Special Publication No. 05-003324 Japanese Patent Application Publication No. 2001-170432

Conventional support members merely support the object to be accommodated, but do not have a structure capable of suppressing vibrations of the object to be accommodated.

The present invention has been made in view of the above points. The purpose is to provide a chamber box that can suppress vibrations of the object to be accommodated.

The characteristics of the chamber box according to the present invention are as follows:
A chamber box capable of accommodating an object and in which air flows from upstream to downstream in a space accommodating the object ,
The object to be accommodated is
a first end that is held in a predetermined position of the chamber box and serves as a fixed end;
a second end that is spaced apart from the first end and becomes a free end within the chamber box;
The chamber box and the second end are connected in a direction perpendicular to the air flow flowing from upstream to downstream , and the chamber box is selectively connected along the air flow flowing from upstream to downstream with respect to the chamber box. A connecting member is positioned and extends perpendicularly to the flow of air flowing from upstream to downstream .

Even when force is applied from the flowing fluid, vibration of the accommodated body can be suppressed.

As shown in FIGS. 1 and 2, the chamber box 100 is placed in the middle of an air conditioning duct 200. The chamber box 100 may be placed together with the air conditioning duct 200 when it is installed, or may be additionally placed on the existing air conditioning duct 200.

The chamber box 100 has a substantially rectangular parallelepiped shape. Chamber box 100 has a hollow shape. Chamber box 100 preferably has a rectangular cylindrical shape. Note that the chamber box 100 may have a cylindrical shape.

Since the chamber box 100 is hollow, it is possible to secure an accommodation space CS for accommodating the air purification unit 300. As shown in FIGS. 1 to 3, the air cleaning unit 300 is housed in a housing space CS formed by the air conditioning duct 200.

The chamber box 100 is made of thin metal such as aluminum or stainless steel. The chamber box 100 may be made of resin such as plastic, glass, or the like. The material of the chamber box 100 may be appropriately selected in consideration of strength, heat conduction, weight reduction, etc.

<<6 walls>>
Chamber box 100 has six walls. Specifically, the chamber box 100 has an upstream wall 112 and a downstream wall 116, an upper wall 122, a lower wall 124, a front wall 126, and a rear wall 128.

<Upstream wall 112, downstream wall 116>
Upstream wall 112 and downstream wall 116 are positioned opposite each other. The upstream wall 112 and the downstream wall 116 have a thin plate-like substantially rectangular shape. The upstream wall 112 and the downstream wall 116 correspond to a cross section along a direction perpendicular to the direction from upstream to downstream.

The upstream wall 112 is located on the upstream side of the air conditioning duct 200. The upstream wall 112 has an upstream communication port 114 . The upstream wall 112 is connected to an air conditioning duct 200 arranged on the upstream side. Air from the air conditioner flows into the chamber box 100 via the upstream communication port 114.

The downstream wall 116 is located on the downstream side of the air conditioning duct 200. The downstream wall 116 has a downstream communication port 118. The downstream wall 116 is connected to an air conditioning duct 200 located downstream. Air from the chamber box 100 flows out through the downstream communication port 118 to the air conditioning duct 200 on the downstream side.

<Top wall 122, bottom wall 124, front wall 126, rear wall 128>
The upper wall 122, the lower wall 124, the front wall 126, and the rear wall 128 have a substantially rectangular thin plate shape. The upper wall 122 and the lower wall 124 are arranged in parallel and facing each other. The front wall 126 and the rear wall 128 are arranged parallel to each other and facing each other. A substantially rectangular cylindrical shape is defined by the upper wall 122, the lower wall 124, the front wall 126, and the rear wall 128.

A hollow accommodation space CS is defined by a space surrounded by the upstream wall 112, the downstream wall 116, the upper wall 122, the lower wall 124, the front wall 126, and the rear wall 128. In the accommodation space CS of the chamber box 100, air mainly flows from upstream to downstream.

<Hooks 132, 134 and wires 136, 138>
Hooks 132 and 134 are provided at the upstream and downstream ends of the top wall 122, respectively. For example, eye bolts or the like can be used as the hooks 132 and 134. A lower end of a wire 136 is removably connected to the hook 132, and a lower end of a wire 138 is removably connected to the hook 134.

As shown in FIG. 1, the chamber box 100 and the air conditioning duct 200 are generally arranged in an arrangement space LS formed in a ceiling, an attic, under a floor, behind a wall, or the like. An upper end of the wire 136 and an upper end of the wire 138 of the chamber box 100 may be fixed to the upper surface (not shown) of the placement space LS. The chamber box 100 can be suspended by hooks 132, 134 and wires 136, 138. Note that the hooks 132, 134 and the wires 136, 138 are not limited to the hooks 132, 134, and any other material may be used as long as the chamber box 100 can be provided at a fixed position.

As will be described later, the air purification unit 300 may be attached to the chamber box 100 and become heavy. Even when the chamber box 100 becomes heavy, by suspending the chamber box 100, it can be stably held in the arrangement space LS. Moreover, even if vibrations occur due to the movement of the air flowing through the chamber box 100, by suspending the chamber box 100, it can be stably held at a constant position in the arrangement space LS.

<Rear opening>
Chamber box 100 has a rear opening (not shown). A rear opening is formed in rear wall 128. An air purification unit 300, which will be described later, can be installed in the chamber box 100 through the rear opening. The air purifying unit 300 is fixed to the chamber box 100 with a fastening member such as a bolt. Note that in consideration of ease of maintenance and repair work, an opening is provided on the front side of the front wall 126 (not shown), and the air purifying unit 300 is removably attached to the rear wall 128 through the opening. You may.

Note that the specific method of fixing the air cleaning unit 300 to the chamber box 100 is not limited to this. For example, the air cleaning unit 300 may be fixed to the chamber box 100 via a reinforcing member (not shown). Furthermore, the air purifying unit 300 may be attached to the chamber box 100 using a fastening member other than a bolt or a locking member such as a hook.

<<Other aspects of chamber box 100>>
The shape of the chamber box 100 is not limited to a rectangular tube shape, but may be a cylindrical shape. Further, the shape of the chamber box 100 may be a polygonal cylinder such as a pentagonal cylinder or a hexagonal cylinder.

The outer surface of chamber box 100 may be covered with a heat insulating member (not shown). The flowing air can be guided from upstream to downstream without changing its temperature.

The inner surface of the chamber box 100 may be formed smoothly with less unevenness. Air can flow smoothly by reducing pressure loss.

<<<Air purification unit 300>>>
FIG. 4 is a perspective view showing the appearance of the air cleaning unit 300. FIG. 5 is a perspective view showing the configuration of the air cleaning unit 300. FIG. 6 is a perspective view showing a state when a photocatalyst filter cassette 340, which will be described later, is removed from the state shown in FIG. FIG. 7 is a cross-sectional view showing the arrangement of the photocatalyst filter 344, the catalyst activation light source 350, and the inactivation light source 360.

The air purification unit 300 includes a photocatalyst filter cassette 340, a catalyst activation light source 350, and an inactivation light source 360.

<Photocatalyst filter cassette 340>
The photocatalyst filter cassette 340 includes a photocatalyst filter 344 that supports a photocatalyst. The photocatalyst filter cassette 340 is formed in a cassette shape so as to be detachable.

<Light source 350 for catalyst activation>
The catalyst activation light source 350 emits ultraviolet light. The ultraviolet light emitted from the catalyst activation light source 350 is irradiated onto the photocatalyst filter 344 of the photocatalyst filter cassette 340 . The photocatalyst of the photocatalyst filter 344 is activated by irradiation with ultraviolet light. The configuration of the photocatalyst filter 344 will be described later.

<Inactivation light source 360>
The inactivation light source 360 emits ultraviolet light with a shorter wavelength than the ultraviolet light emitted from the catalyst activation light source 350. The ultraviolet light emitted from the inactivation light source 360 is irradiated onto the photocatalyst filter 344 of the photocatalyst filter cassette 340. By irradiating the photocatalyst filter 344 with ultraviolet light having a shorter wavelength than the ultraviolet light emitted from the catalyst activation light source 350, bacteria and viruses are inactivated.

The air purification unit 300 also includes an outer plate 310, a filter guide rail 320, and a light source support frame 330.

<Outer panel 310>
The outer plate 310 has a rectangular shape. The outer plate 310 is a plate for holding the filter guide rail 320 and attaching the air purification unit 300 to the air conditioning duct 200.

<Filter guide rail 320>
The filter guide rail 320 is a member for detachably supporting the photocatalyst filter cassette 340. The filter guide rail 320 is provided so as to protrude into the air conditioning duct 200 from the inner surface of the outer plate 310 (the surface facing into the air conditioning duct 200).

<Light source support frame 330>
The light source support frame 330 has an elongated shape. The light source support frame 330 is provided so as to protrude from the inner surface of the outer panel 310 into the air conditioning duct 200. The light source support frame 330 is provided with a catalyst activation light source 350 or an inactivation light source 360.

<Photocatalyst filter 344>
Photocatalyst filter cassette 340 has a photocatalyst filter 344. The photocatalyst filter 344 supports a photocatalyst that exhibits a photocatalytic function upon irradiation with ultraviolet rays.

In this embodiment, the photocatalyst filter 344 has a structure in which a photocatalyst containing apatite, titanium oxide, or the like is supported on the surface of a filter base made of an inorganic material such as stainless steel or aluminum.

The filter base is made of, for example, a nonwoven fabric made of a fibrous material made of stainless steel, aluminum, or the like, or an expanded metal or punched metal made of stainless steel, aluminum, or the like. By using a filter base made of an inorganic material such as stainless steel or aluminum, deterioration of the filter base can be suppressed, and maintenance and replacement frequency can be reduced.

The method of supporting the photocatalyst includes a method of coating the surface of a filter base material, and a method of supporting a particulate photocatalyst within the fibrous body when a fibrous base material is used. The method of supporting the catalyst on the surface of the filter base material is preferable in that it can easily receive the ultraviolet rays emitted from the light source 350 for catalyst activation. On the other hand, a method in which a fibrous material, a mesh, or a punched metal is supported as a base material is preferable because it can increase the contact area with the air flowing in the air conditioning duct 200 and lengthen the contact time with the photocatalyst.

In this embodiment, photocatalyst filter cassette 340 includes a photocatalyst filter 344 and a filter frame 342. The photocatalyst filter 344 is held by the filter frame 342. The photocatalyst filter 344 extends in a flat shape by being held by the filter frame 342. Although two photocatalyst filter cassettes 340 are used in this embodiment, the number of photocatalyst filter cassettes 340 is not limited to this, and may be one or three or more.

<Support of photocatalyst filter cassette 340>
The photocatalyst filter cassette 340 is detachably supported by a pair of filter guide rails 320 facing each other.

The filter guide rail 320 has an elongated shape. The filter guide rail 320 has a distal end side (projecting end side (side away from the outer plate 310)) and a base end side (outer plate 310 side).

The filter guide rail 320 has a substantially U-shaped cross section. The filter guide rail 320 has a bottom groove portion and two side wall portions. The two side walls protrude from the bottom groove with the bottom groove in between, and are parallel to each other and face each other. An opening is formed by two side walls spaced apart from each other.

The pair of filter guide rails 320 are arranged such that their openings face each other and their bottom grooves are separated from each other.

In this embodiment, air purification unit 300 has two photocatalyst filter cassettes 340. A pair of filter guide rails 320 facing each other is used for each of the two photocatalyst filter cassettes 340.

The photocatalyst filter cassette 340 is held between a pair of filter guide rails 320 that face each other. Slide the end of the photocatalyst filter cassette 340 into the opening of the filter guide rail 320 from the tip side (projecting end side) to the base end side (outer plate 310 side) of the pair of filter guide rails 320 facing each other. Insert it. In this way, the photocatalyst filter cassette 340 is attached to the outer plate 310 via the pair of filter guide rails 320.

The filter frame 342 of the photocatalyst filter cassette 340 has a locking piece 346. The locking piece 346 protrudes toward the side facing the filter guide rail 320. The locking piece 346 protrudes in a direction perpendicular to the sliding direction of the photocatalyst filter cassette 340 (that is, a direction perpendicular to the normal direction of the photocatalyst filter 344). On the other hand, the filter guide rail 320 has a locking hole 322.

When the photocatalyst filter cassette 340 is mounted on the filter guide rail 320, the locking piece 346 of the photocatalyst filter cassette 340 is locked in the locking hole 322 of the filter guide rail 320. Thereby, the photocatalyst filter cassette 340 is fixed at a predetermined position on the filter guide rail 320.

<Catalyst activation light source 350 and inactivation light source 360>
The catalyst activation light source 350 is a light source for irradiating the photocatalyst filter cassette 340 with ultraviolet light to activate the photocatalyst. The inactivation light source 360 is a light source for inactivating bacteria and viruses. By configuring the light source 350 for catalyst activation and the light source 360 for inactivation separately rather than in common, it is possible to achieve both the deodorizing effect of activating the photocatalyst and the effect of inactivating bacteria and viruses. , it becomes possible to get enough. In particular, the air conditioning duct 200 processes a large amount of air compared to a normal indoor air cleaner or the like. Therefore, in order to obtain sufficient effects of deodorization and inactivation of bacteria, etc., it is desirable to configure the catalyst activation light source 350 and the inactivation light source 360 separately.

The catalyst activation light source 350 includes a plurality of light emitting diodes 352. The plurality of light emitting diodes 352 are arranged substantially in a straight line. The inactivation light source 360 has a plurality of light emitting diodes 362. The plurality of light emitting diodes 362 are arranged substantially in a straight line. By configuring the catalyst activation light source 350 with the light emitting diode 352 and the inactivation light source 360 with the light emitting diode 362, for example, compared to the case where an ultraviolet lamp is used, the catalyst activation light source 350 and the inactivation light source 350 are The size of the light source 360 can be reduced. Specifically, the catalyst activation light source 350 and the inactivation light source 360 can be formed thin. By doing so, it is possible to suppress an increase in air resistance within the air conditioning duct 200 due to the catalyst activation light source 350 and the inactivation light source 360. Therefore, the catalyst activation light source 350 and the inactivation light source 360 can also be applied to the small (thin) air conditioning duct 200.

Furthermore, by configuring the catalyst activation light source 350 with a light emitting diode 352 and configuring the inactivation light source 360 with a light emitting diode 362, power consumption can be reduced compared to, for example, a case where an ultraviolet lamp is used.

Furthermore, light emitting diodes 352 and 362 have a long lifespan, such as not requiring replacement of the light emitting diodes for more than five years. Therefore, compared to ultraviolet lamps that must be replaced about once a year, the labor and running costs for replacement can be reduced, and maintainability can be improved. In particular, as in this embodiment, by separately configuring the catalyst activation light source 350 with the light emitting diode 352 and the inactivation light source 360 with the light emitting diode 362, the effect can be greatly increased.

As the light emitting diode 352 constituting the light source 350 for catalyst activation, a light emitting diode that emits ultraviolet light with a wavelength of 360 nm or more and 380 nm or less is used. In this embodiment, a light emitting diode 352 that emits ultraviolet light with a wavelength of 365 nm is used as the light source 350 for catalytic activation.

As the light emitting diode 362 constituting the inactivation light source 360, one that emits ultraviolet light with a shorter wavelength than the light emitting diode 352 constituting the catalyst activation light source is used. More specifically, as the light emitting diode 362 constituting the inactivation light source 360, a light emitting diode that emits deep ultraviolet light with a wavelength of 250 nm or more and 280 nm or less is used. In this embodiment, a light emitting diode 362 that emits deep ultraviolet light with a wavelength of 280 nm is used as the inactivation light source 360.

As shown in FIG. 6, a plurality of light emitting diodes 352 are arranged in a substantially straight line on the light source support frame 330, and constitute the light source 350 for catalytic activation. A plurality of light emitting diodes 362 are arranged in a substantially straight line on the light source support frame 330, and constitute the inactivation light source 360. The light source support frame 330 on which the light emitting diode 352 is disposed and the light source support frame 330 on which the light emitting diode 362 is disposed are arranged parallel to each other and spaced apart from each other. Therefore, the plurality of light emitting diodes 352 and the plurality of light emitting diodes 362 are arranged in a matrix as a whole (on the intersections of the plurality of lattices).

In this embodiment, air purification unit 300 has two photocatalyst filter cassettes 340. The two photocatalyst filter cassettes 340 are arranged facing each other and separated from each other. A catalyst activation light source 350 and an inactivation light source 360 are arranged between the photocatalyst filters 344 of the two photocatalyst filter cassettes 340.

As shown in FIGS. 6 and 7, the air purification unit 300 includes a total of four catalyst activation light sources 350 and two inactivation light sources 360. Six light source support frames 330 are provided to protrude from the outer panel 310. The six light source support frames 330 extend perpendicularly from the outer panel 310. The six light source support frames 330 are arranged parallel to each other and spaced apart from each other. Each of the four catalyst activation light sources 350 and the two inactivation light sources 360 is attached to the light source support frame 330.

Two light sources 350 for catalytic activation and one light source 360 for inactivation are arranged in correspondence with each of the two photocatalyst filters 344 . Two catalyst activation light sources 350 corresponding to each of the photocatalyst filters 344 are arranged in parallel with one inactivation light source 360 interposed therebetween. The ultraviolet rays emitted from the two catalyst activation light sources 350 and one inactivation light source 360 proceed toward the corresponding photocatalyst filters 344 and are irradiated therewith.

The light source 350 for catalyst activation is arranged at a position farther from the photocatalyst filter cassette 340 than the light source 360 for inactivation. Thereby, even if the photocatalyst filter 344 is relatively large in size, the entire photocatalyst filter 344 can be irradiated with ultraviolet light from the catalyst activation light source 350, and a sufficient photocatalyst activation effect can be obtained. Moreover, the light source 360 for inactivation is arranged at a position closer to the photocatalyst filter cassette 340 than the light source 350 for catalyst activation. This makes it possible to sufficiently inactivate bacteria and viruses by the inactivating light source 360.

As shown in FIG. 7, the catalyst activation light source 350 and the inactivation light source 360 are installed so that the emitted ultraviolet light goes from the inside (center side in the air conditioning duct 200) to the outside (inner wall side of the air conditioning duct 200). It is being Thereby, the wiring for the catalyst activation light source 350 and the inactivation light source 360 can be gathered in the center of the air purification unit 300, and the wiring layout can be simplified. However, the present invention is not limited to this, and the catalyst activation light source 350 and the inactivation light source 360 are provided so as to emit ultraviolet light from the outside (inner wall side of the air conditioning duct 200) to the inside (center side inside the air conditioning duct 200). It's okay. In this case, since the inner wall of the air conditioning duct 200 is less likely to be irradiated with ultraviolet light, deterioration of the air conditioning duct 200 can be suppressed.

As shown in FIG. 4, a handle 312 is provided on the front side of the outer panel 310 (the surface exposed to the outside of the air conditioning duct 200). An operator can grip the handle 312 to attach and detach the air purifying unit 300 to and from the air conditioning duct 200.

A power jack 314 is provided on the front side of the outer panel 310. A power plug (not shown) is inserted into the power jack 314. The power plug is provided at the end of a power cord (not shown) extending from a power supply device (not shown).

A notification light emitting diode 316 is provided near the power jack 314. The notification light emitting diode 316 notifies the state of power supply, the driving state of the catalyst activation light source 350 and the inactivation light source 360, etc. by emitting light.

<Proximal end portion 302 and distal end portion 304>
The base end side (the side closest to the outer plate 310) of the filter guide rail 320 is the base end portion 302 of the air cleaning unit 300. The distal end side (the protruding end side (the side farthest from the outer plate 310) of the filter guide rail 320 is the distal end portion 304 of the air cleaning unit 300.

FIG. 8 is a perspective view showing the connection structure 1 between the air cleaning unit 300 and the chamber box 100. In addition, in FIG. 8, the outline of the air cleaning unit 300 is shown with a solid line for the sake of simplicity. Further, in FIG. 8, for clarity, only the front wall 126 of the chamber box 100 is shown, and other walls are omitted. FIG. 9 is a sectional view showing the connection structure 1 between the air purification unit 300 and the chamber box 100.

The connection structure 1 between the air purification unit 300 and the chamber box 100 includes a plurality of protrusions 152 and a connection body 172. The plurality of protrusions 152 are provided on the front wall 126, and the connector 172 is provided on the air purification unit 300. The connecting body 172 is installed between the air purifying unit 300 and the protrusion 152 of the front wall 126, thereby forming a connecting structure between the air purifying unit 300 and the chamber box 100.
