In order to achieve the above object, according to the present invention, as described in claim 1, air is sucked from the air passage body and the inlet of the air passage body and discharged from the outlet. An air processing unit comprising a fan, and a box-shaped air processing unit for processing air flowing by the fan, which is detachably mounted inside the air passage body. As a dust collecting unit for removing dust contained in the air and a treating agent unit for removing odor, mist or harmful gas contained in the air, and these two types of units are optional. It is configured to be selected and attached to.

According to this, only the dust collecting unit or only the treating agent unit can be attached to the air passage body, and the dust collecting function similar to the conventional one can be obtained. The deodorizing function and the function of removing mist and harmful gas can be obtained by changing the treating agent. At this time, the box-shaped air treatment unit means that the treatment agent unit contains a sufficient amount of the treatment agent, and a sufficient amount of the treatment agent has a deodorizing function or mist or Sufficient removal function of harmful gas.

According to the second aspect of the present invention, there is provided an air passage body and a fan for sucking air from the inlet of the air passage body to let it out from the outlet, and a fan is provided inside the air passage body. An air circulation processor that treats flowing air and is detachably mounted with a plurality of box-shaped air treatment units, wherein the air treatment unit removes dust contained in the air. The dust collecting unit and the treatment agent unit for removing odor, mist or harmful gas contained in the air are provided, and these two types of units are simultaneously mounted.

According to this, a dust collecting function and a strong deodorizing function can be obtained at the same time. It should be noted that the air passage body may be equipped with only one of the dust collecting unit and the treating agent unit.

The above inventions are embodied as follows.
That is, as described in claim 3, the dust collecting unit and the treating agent unit are arranged in parallel with the air flow in the air passage. According to this, the dust collecting function and the deodorizing, mist or harmful gas removing function can be obtained at the same time, and the resistance of the dust collecting unit or the treating agent unit to the flow of air in the air passage is relatively small. Becomes

Alternatively, as described in claim 4, 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 in which dust is unlikely to adhere.

The treating agent unit is as follows. That is, as described in claim 5, a box body that allows air to pass through in a specific direction is provided, and the processing agent spaces are arranged in a staggered manner inside the box body. According to this

FIG. 3A is a plan cross-sectional view of the processing machine, FIG. 4 is a view showing a processing agent unit of the processing machine,
FIG. 5A is a diagram showing a state in which the treatment agent unit is opened.

1 to 3, reference numeral 1 is an air passage body suspended from a ceiling 2 in a specific space of a building. The passage body 1 is provided with upper and lower horizontal plates 3a and 3b and upright and left standing members. Side plate 4
The square cylinder is surrounded by a and 4b, and the grill 5 is attached to the entrance p1 which is the front opening of the square cylinder, and the louver 6 which has a variable wind direction is attached to the exit p2 which is the rear opening. There is.

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 let it flow out from the outlet p2.

Both 8a and 8b are box-shaped air treatment units. The units 8a and 8b have the same outer shape and are detachably mounted inside the air passage body 1.

The mounting structure of the air treatment 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 below the air passage body 1.
The door plate 9 is attached to the rear edge of the opening a via the hinge b as a part of the horizontal plate 3b so that the door plate 9 can be opened and closed, and the maximum opening position of the door body 9 is restricted. The link member 10 is attached to the left and right standing side plates 4a and 4b and the door 9
And a lock member 11 for restricting the door body 9 to the closed position is mounted on the front end edge of the door body 9 so as to be capable of releasing the restriction.

A unit support frame 12 for arranging two air treatment units 8a, 8b in parallel with the air flow in the air passage body 1 on the inner surface of the door body 9 so as to be detachably fixed.
This 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 treatment units 8a, 8b are tightly fitted therein, and the left and right portions of the upper edge of the pair of front and rear perforated plate members c, c. In addition, the retaining members e, e for restricting the withdrawal of the air treatment units 8a, 8b are arranged in a bridging shape and fixed by bolts.

The details of the air treatment units 8a and 8b will be described below. That is, of the two air treatment units 8a and 8b, one 8a is a dust collecting unit and the other 8a is a treating agent unit. These two types of units 8a, 8
In addition to those mounted in the air passage body 1, b is preferably manufactured in an appropriate number for replacement mounting for convenient use.

The dust collecting unit 8a is already known and comprises an ionizer section 13 and a dust collecting section 14. The ionizer section 13 holds dust in the air at an ionization line held at + potential and at zero potential. The ionization auxiliary electrode is used to ionize the ionized dust, and the dust collecting unit 14 associates the ionized dust with the dust collecting electrode held at zero potential and the corresponding electrode held correspondingly at + potential. Is moved to the dust collecting electrode side and collected on the upper surface thereof.

On the other hand, the treatment agent unit 8b forms a box body 15 as shown in FIG. 4, and the treatment agent is contained in the inside thereof. Examples of the treating agent include a deodorizing agent, a mist treating agent, a harmful gas treating agent and the like, which are already on the market. The box body 15 is composed of a rectangular main body portion 15a having an open upper surface and a lid portion 15b for closing the upper surface of the main body portion 15a, and the front surface plate g1 and the rear surface plate g2 of the main body portion 15a have a large number of parts. An air circulation hole h is formed, and the lid 15b is bolted to the upper edge of the main body 15a and has a handle i fixed to the upper surface. As shown in FIG. 5A, the inside of the main body portion 15a is provided with left-right standing partition surface members j and front-rear standing partition surface members k arranged in a grid, and in a zigzag arrangement in the unit space corresponding to each grid. The processing agent space m is formed as described above, and a mesh bag or cloth bag containing activated carbon particles as a processing agent is inserted inside the space m.

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

Next, an example of use and operation of the air circulation treatment machine configured as described above will be described. As shown in FIG. 1, the sirocco fan 7 is rotated under the condition that the dust collecting unit 8a and the treatment 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 of the inlet p1, passes through the dust collection unit 8a and the treatment agent unit 8b in parallel, and then flows out from the louver 6.

During such air flow, the dust collecting unit 8
Inward of a, the dust contained in the flowing air is sequentially ionized by the ionizer unit 13, and sequentially adsorbed by the dust collecting electrode by the dust collecting unit 14 to be removed.

On the other hand, in the inside of the treatment agent unit 8b, the flowing air passes through the spaces between the activated carbon particles and the like, and the odors and the like are removed by the activated carbon particles during the passage, and the box body 15 In the unit space in which the activated carbon particles or the like are not accommodated, when the flow resistance of the air in the box body 15 is about to increase, the air flow in the thin layer portion of the activated carbon particles or the like increases. It acts so as to prevent the flow resistance from becoming excessive.

Therefore, of the air flowing into the air passage body 1 from the grill 5, a part of the air is removed by the dust collecting unit 8a, and the other is removed from the treating agent unit 8b.
After being deodorized, the air flows out through the louver 6, and such air treatment is continuously performed on the air in the specific space that passes through the air passage body 1 and circulates. The air is gradually purified. At this time, the two air treatment units 8a and 8b are connected to the air passage body 1.
The fact that they are arranged in parallel with the air flow in the air passage body 1 reduces the flow resistance of these aerial processing units 8a, 8b to the air flow in the air passage body 1.
It contributes to smooth air flow inside.

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

In the above-mentioned usage example, the case where the treating agent unit 8b is used to remove odors or the like by using activated carbon particles has been explained. However, various mist such as humidity, odorless or odorous. These removal treatments can also be performed by using a treating agent for removing harmful gases.

A dust collecting unit 8 is provided inside the air passage body 1.
Although a and the treatment agent unit 8b are attached, it is also possible to attach the two treatment agent units 8b and 8b without attaching the dust collecting unit 8a, and conversely two treatment agent units 8b are not attached. Dust collection unit 8a, 8a
It is also possible to put on. As a result, it is possible to strongly perform any desired treatment, such as treatment with a treating agent such as deodorization or dust collection treatment.

Next, a modification of the above embodiment will be described. FIG. 3B is a cross-sectional plan view showing this modified example, and FIG. 5B is a box body 15 of the processing agent unit 8b used in this modified example.
It is a figure which shows the main-body part 15a. As shown in FIG. 3B, the dust collecting unit 8a and the treating 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, the treatment agent unit 8b is preferably configured such that the treatment agent spaces m and the empty spaces n are alternately arranged in layers inside the box body 15 in a direction intersecting the air permeation direction.

The processing agent unit 8b is shown in FIG.
As shown in B, a rectangular interposer 15c as shown by the alternate long and short dash line is arranged inside the main body 15a of the box body 15, and activated carbon particles or the like are placed in the unit space r partitioned by these rectangular interposers 15c. The net bag or the cloth bag containing the treatment agent is inserted, and the rectangular interposer 15c is set to allow air to pass therethrough. The other structure is substantially the same as that of the previous embodiment.

In this modification, the air after the dust is removed by the dust collecting unit 8a flows into the processing agent unit 8b,
Subsequently, the rectangular interposer 15c and activated carbon particles pass through the interstices, and flow out rearward. Therefore, dust in the air is less likely to adhere to the activated carbon particles and the flow resistance of the unit 8b with respect to the air passing through the unit 8b is such that the air can pass through the rectangular interposer 15c without receiving the resistance. Therefore, it is relatively small.

According to the present invention configured as described above,
The following effects can be obtained. That is, according to the first aspect, the dust collecting function similar to the conventional one can be obtained, and the deodorizing function and the mist and harmful gas removing function can be sufficiently exerted.

According to the second aspect, it is possible to perform a strong deodorizing process concurrently with the dust collecting process.

According to the third aspect of the present invention, the dust collecting process and the deodorizing process, the mist removing process or the harmful gas removing process can be simultaneously performed, and the collection process for the flow of air in the air passage body can be performed. The resistance due to the dust unit and the treatment agent unit can be made relatively small.

According to the fourth aspect, the dimension of the air passage body orthogonal to the flow direction of the air can be made smaller than that of the third aspect, and the treating agent unit is the dust collecting unit. By arranging the processing agent in the rear of the processing agent unit, it is possible to prevent dust from adhering to the processing agent in the processing agent unit.

According to the fifth aspect, it is possible to suppress an increase in the resistance of the treatment agent unit against the flow of air and to exert a relatively good deodorizing function.

According to the sixth aspect, it is possible to reduce the resistance of the processing agent unit against the flow of air.
