To be mounted.

[0005] According to this, it is possible to mount only the dust collecting unit or only the treating agent unit in the air passage body, so that a dust collecting function similar to the conventional one can be obtained. By changing the treating agent, a deodorizing function and a function of removing mist and harmful gas can be obtained. At this time, the fact that the air treatment unit is box-shaped means that the treatment agent unit accommodates a sufficient amount of the treatment agent, and a sufficient amount of the treatment agent has a deodorizing function or mist or The function of removing harmful gas is sufficient.

According to this, a strong deodorizing function can be obtained at the same time as the dust collecting function is obtained. The air passage may be provided with only one of the dust collection unit and the treatment agent unit.

Each of the above-mentioned inventions is embodied as follows.
That is, as described in claim 3, the dust collection unit and the treatment agent unit are arranged in parallel with the flow of air in the air passage. According to this, in addition to simultaneously obtaining the dust collecting function and the deodorizing, mist or harmful gas removing function, the resistance of the dust collecting unit and the treating agent unit to the flow of air in the air passage is relatively small. Becomes

Alternatively, the dust collecting unit and the treating agent unit may be arranged in series with respect to the flow of air in the air passage. According to this, the dimension of the air passage body in the direction orthogonal to the air flow direction is smaller than that of the third aspect. Further, by positioning the treatment agent unit behind the dust collection unit, air with less dust flows into the treatment agent unit, and the treatment agent in the treatment agent unit is in a state where dust hardly adheres.

The processing agent unit is as follows. That is, as described in the fifth aspect, a structure is provided in which a box body that allows air to pass in a specific direction is provided, and the processing agent spaces are staggered inside the box body. According to this,

FIG. 5A is a view showing a state where the treatment agent unit is opened.

1 to 3, reference numeral 1 denotes an air passage body suspended from a ceiling 2 in a specific space of a building. The passage body 1 includes upper and lower horizontal plates 3a and 3b and left and right standing members. Side plate 4
a square tube surrounded by a and 4b, a grille 5 is mounted on an inlet p1 which is a front opening of the square tube, and a louver 6 which is variable in wind direction is mounted on an outlet p2 which is a rear opening. I have.

Reference numeral 7 denotes a sirocco fan mounted inside the air passage body 1, which is driven by a motor (not shown) to suck air from the inlet p1 and to flow out from the outlet p2.

Each of 8a and 8b is a box-shaped air processing unit. Each of the units 8a and 8b has the same outer shape and is detachably mounted inside the air passage body 1.

The mounting structure of the air processing units 8a and 8b will be described below with reference to FIG.
That is, the opening a is formed in a part of the horizontal plate 3b on the lower side of the air passage body 1.
A door plate 9 is attached to the rear edge of the opening a via a hinge b so as to be freely openable and closable as a part of the horizontal plate 3b, and a regulation for regulating a maximum opening position of the door body 9 is provided. The link member 10 is connected to the left and right standing side plates 4a and 4b and the door body 9.
And lock members 11, 11 for restricting the door 9 to the closed position are mounted on the front edge of the door 9 so as to be able to release the restriction.

On the inner surface of the door body 9, a unit support frame 12 for arranging two air processing units 8a and 8b in parallel with the air flow in the air passage body 1 so as to be detachably fixed.
The unit support frame 12 includes a pair of front and rear perforated plate members c, c fixed to the left and right portions of the inner surface of the door body 9 and a pair of left and right side plate members d, d. In addition to being connected in a rectangular shape, the inner space is sized so that the two air processing units 8a and 8b are tightly fitted inside, and the left and right portions of the upper end edge of the pair of front and rear perforated plate members c and c In addition, the retaining members e, e for regulating the removal of the air treatment units 8a, 8b are arranged in a bridge shape and fixed by bolts.

Next, the details of the air treatment units 8a and 8b will be described. That is, of the two air treatment units 8a and 8b, one 8a is a dust collection unit and the other 8b is a treatment agent unit. These two types of units 8a, 8
It is preferable from the viewpoint of convenient use that an appropriate number of replacement b besides the one mounted in the air passage body 1 be replaced.

The above-mentioned dust collecting unit 8a is already known and comprises an ionizer section 13 and a dust collecting section 14. The ionizer section 13 keeps dust in the air at an ionization line held at a positive potential and at a zero potential. The dust collecting unit 14 converts the ionized dust into a dust collecting electrode held at zero potential and a corresponding action between the dust collecting electrode and the corresponding electrode held at + potential. Then, it is moved to the dust collecting electrode side and collected on the upper surface thereof.

On the other hand, the processing agent unit 8b forms a box body 15 as shown in FIG. 4, in which the processing agent is accommodated. Examples of the treating agent include a deodorizing treating agent, a mist treating agent, a harmful gas treating agent, and the like, which are already commercially available. The box 15 includes a rectangular main body 15a having an open upper surface and a lid 15b for closing the upper surface of the main body 15a. A large number of front and rear plates g1 and g2 are provided on the main body 15a. An air circulation hole h is formed, and the lid 15b is fixed to the upper end edge of the main body 15a by bolts and a handle i is fixed to the upper surface. As shown in FIG. 5A, the inside of the main body 15a is provided with a left-right standing partition member j and a front-rear rising partition member k arranged in a lattice, and a staggered arrangement in a unit space corresponding to each lattice. Is formed as a treating agent space m, and a mesh bag or cloth bag containing activated carbon particles or the like as a treating agent is inserted into the space m.

At this time, the left-right standing partition member j and the front-rear rising partition member k have a structure through which air can pass as easily as possible. The treatment agent may be variously changed, and the treatment agent may be directly inserted into the unit space without being accommodated in a net bag or cloth bag.

Next, a description will be given of an example of the use and operation of the air circulation processing apparatus configured as described above. As shown in FIG. 1, the sirocco fan 7 is rotated while the dust collection unit 8a and the processing agent unit 8b are mounted inside the air passage body 1. As a result, the air in the specific space flows into the air passage body 1 from the grill 5 at the inlet p1, passes through the dust collection unit 8a and the treatment agent unit 8b in parallel, and then flows out of the louver 6.

While the air is flowing, the dust collection unit 8
Inside of a, dust contained in the flowing air is sequentially ionized by the ionizer 13, and sequentially adsorbed and removed by the dust collecting electrode by the dust collecting unit 14.

On the other hand, inside the treatment agent unit 8b, the flowing air passes between particles such as activated carbon particles, and during this passage, the activated carbon particles and the like remove odor and the like. Among the unit spaces within the box, those containing no activated carbon particles or the like increase the air flow in the thin layer portion of the activated carbon particles or the like when the flow resistance of the air in the box 15 is going to be excessive. To prevent the flow resistance from becoming excessive.

Therefore, of the air that has flowed into the air passage 1 from the grill 5, some of the air is removed by the dust collection unit 8 a, and the others are treated agent units 8 b
After the air is deodorized, the air flows out through the louver 6, and such air treatment is continuously performed on the air in the specific space that circulates through the air passage body 1. Is gradually purified. At this time, the two air processing units 8a and 8b
The arrangement of the air processing units 8a and 8b in parallel with the air flow in the air passage unit 1 reduces the flow resistance of the air treatment units 8a and 8b to the air flow in the air passage unit 1 and
It contributes to the smooth flow of air inside.

If such processing is performed for a long time, dust accumulates in the dust collecting unit 8a, and the processing ability such as deodorization of the processing agent in the processing agent unit 8b is lost. Therefore, when a certain period of time has elapsed, the lock members 11 and 11 are operated to open the door 9 as shown in FIG. 2, and the dust collection unit 8a and the treatment agent unit 8b are replaced with spare ones. Alternatively, after removing dust in the dust collection unit 8a or replacing the processing agent such as activated carbon particles in the processing agent unit 8b, these units 8a and 8b are mounted again. At this time, the treating agent such as used activated carbon particles taken out of the air passage body 1 is regenerated for the next use.

In the above-mentioned use example, the case where the odor or the like is removed by using the activated carbon particles or the like in the treatment agent unit 8b has been described. However, various mist such as moisture, odorless or odorous, etc. These removal treatments can be performed using a treatment agent for removing harmful gases.

The dust collecting unit 8 is provided inside the air passage body 1.
a and the processing agent unit 8b are mounted, but it is also possible to mount the two processing agent units 8b and 8b without mounting the dust collection unit 8a, and conversely, to mount the two processing agent units 8b without mounting the processing agent unit 8b. Dust collection units 8a, 8a
You can also attach. This makes it possible to strongly perform any desired processing among the processing with a processing agent such as deodorization or the dust collection processing.

Next, a modification of the above embodiment will be described. FIG. 3B is a cross-sectional plan view showing this modification, and FIG. 5B is a box 15 of a treatment agent unit 8b used in this modification.
It is a figure which shows the main-body part 15a of FIG. As shown in FIG. 3B, the dust collection unit 8a and the treatment agent unit 8b are arranged in series with respect to the air flow indicated by the arrow in the air passage body 1. In this case, it is preferable that the processing agent unit 8b has a configuration in which the processing agent spaces m and the empty spaces n are alternately arranged in layers inside the box 15 in a direction intersecting the direction of air transmission.

The processing agent unit 8b is, for example, as shown in FIG.
As shown in B, inside the main body 15a of the box body 15, a rectangular interposition body 15c as shown by a dashed line is arranged, and activated carbon particles and the like are placed in a unit space r partitioned by the rectangular interposition body 15c. Is inserted into the mesh bag or the cloth bag containing the treating agent. Other configurations are substantially the same as those of the previous embodiment.

In this modification, the air from which dust has been removed by the dust collection unit 8a flows into the treatment agent unit 8b,
Subsequently, it flows backward through the space between the rectangular interposed body 15c and the activated carbon particles. Therefore, dust in the air hardly adheres to the activated carbon particles and the like, and the flow resistance of the unit 8b against the air passing through the unit 8b is such that the air passes through the rectangular intermediary body 15c without receiving the resistance. Becomes relatively small.

According to the third aspect of the present invention, the dust collecting process and the deodorizing, mist or harmful gas removing process can be performed simultaneously in parallel, and the dust collecting process and the flow of the air in the air passage are collected. Resistance due to the dust unit and the processing agent unit can be made relatively small.

According to the fourth aspect, the dimension of the air passage body perpendicular to the direction of air flow can be made smaller than that of the third aspect, and the processing agent unit can be a dust collecting unit. , It is possible to prevent dust from adhering to the processing agent in the processing agent unit.
