Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an air purifying device for preventing indoor air from being contaminated by smoking or the like.

[Background of the invention]

Next, the invention will be explained in detail using FIGS. 13 and 14.

Generally, in order to remove cigarette smoke when smoking indoors and protect the health of non-smokers in the same room, an air purifying device 2 is installed in the indoor space 1 as shown in FIG. There is. The air purifying device 2 has a pretreatment filter 4 for removing coarse particulates, a dust collector 5 for removing cigarette smoke, a deodorizing filter 6 using activated carbon, etc., and a blower 7 built into the housing 3. The process of purifying indoor air entering from an inlet 8 and discharging it from an air outlet 9 is repeated.

Therefore, if the amount of air processed by the air purifying device 2 is appropriate, it is possible to prevent indoor air from being contaminated by smoking, and this is particularly effective for rooms that are closed off for heating and cooling purposes. However, in the installation method shown in FIG. 13, the capacity of the area to be purified by the air purifier 2 is equal to the total volume of the indoor space 1. For this reason, when the volume of the indoor space 1 is large, it is necessary to increase the number of processing scenes of the air purifying device 2 accordingly, resulting in disadvantages such as an increase in the size of the air purifying device 2 and an increase in equipment costs. In addition, the air purifier 2 adds a 13th air filter to the indoor space 1.
A horizontal airflow occurs as shown by the arrow 10 in the figure, and for this reason, when a non-smoker 12 is on the leeward side of the smoker 11 as shown in the figure, there is also the problem that the effect of smoking will be exerted on the non-smoker 12. be.

FIG. 14 shows another installation method for the air purifying device devised by the inventors in the process of arriving at the present invention. In FIG. 14, a smoking space 14 is constructed by partitioning a part of the indoor space 1 with a wall material 13. An air intake port 15 for supplying air to the smoking space 14 is provided near the floor surface of the wall material 13.
An air intake port 8 for the air purifier 2 is provided in the ceiling of the building. The air that has flowed into the air intake port 8 from the smoking space 14 passes through the pretreatment filter 4, the dust collector 5, and the deodorizing filter 6 in order to be purified, and then is pressurized by the blower 7 and is sent to the indoor space outside the smoking space 14. The air is discharged from the air outlet 9 facing 1. The airflow within the smoking space 14 becomes an upward airflow that moves from the air intake 15 of the smoking space 14 to the air intake 8 of the air purifier 2, as shown by the arrow 16 in FIG.

In this method, the area to be purified by the air purifying device 2 is limited to only the smoking space 14, so the processing air volume can be reduced, and the airflow in the smoking space 14 is an upward airflow similar to cigarette smoke, The cigarette smoke generated by the smoker 11 moves upward with the airflow, so it has the advantage that it does not affect the non-smokers 12 in the same room. Since the material 13 is required, the equipment cost increases.

Since the indoor space 1 is divided by the wall material 13, the utilization of the indoor space is restricted. Since the smoking space 14 is isolated by the wall material 13, it has disadvantages such as being difficult for smokers to use.

[Purpose of the invention]

An object of the present invention is to provide an air purifying device that can locally clean a part of an indoor space without using wall materials and prevent indoor air from being contaminated by smoking or the like.

[Summary of the invention]

The present invention includes a casing, an air intake port and an air outlet provided in the casing, a dust collector installed in the casing, and a dust collector formed inside the casing on the upstream side of the dust collector. a second air passage formed on the downstream side of the dust collector inside the casing; and a blower that pressurizes the air in the second air passage and blows it to the air outlet. , the air outlet is configured so that the airflow reaches the indoor space outside the air purifier.
It is arranged so as to form a dividing air curtain, and at least one of the air intake ports faces only one of the two divided indoor spaces and communicates with the first air passage inside the flute body. This is an air purifying device characterized in that it is disposed in a.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

This embodiment is an example in which the air purifier 20 is of a ceiling-mounted type, and a first air intake port 22 and an air outlet 23 are provided on the lower surface of the casing 21 of the air purifier 20 that is installed on the indoor ceiling 1a.
This is provided. If the air purifier is ceiling mounted,
The first air intake port 22, which is the main air intake port, is preferably provided on the lower surface of the housing 21 so as to take in air from the space directly below the air purifier. Immediately after the first air intake port 22, a pretreatment filter 24 for removing coarse particles in the air is installed, and on the downstream side of the pretreatment filter 24 in the housing 21, a dust collector 25 and a deodorizing filter 26 are installed. It is installed. The prefectural dust collector 25 is an electric or mechanical dust collector that can remove even ultrafine particles such as cigarette smoke, and the deodorizing filter 26 uses an absorbent such as activated carbon. installed in combination with A blower 27 is installed further downstream than the deodorizing filter 26 in the housing 21, and
The discharge port 27 is communicated with the air outlet 23. The air outlet 23 is formed in the shape of a slit with a length necessary to generate an air curtain airflow, and FIG. 1 shows its cross section. The internal space of the housing 21 is divided into two by a dust collector 25 and a deodorizing filter 26, and a first air passage 28 is provided between the pretreatment filter 24 and the dust collector 25 on the upstream side.
A second air passage 29 is formed between the deodorizing filter 26 and the blower 27 on the downstream side.

In this embodiment, a second air intake port 30 is further provided on the side surface of the casing 21 opposite to the first air intake port 22 with the air outlet 23 interposed therebetween. The second air intake port 30, which is an auxiliary air intake port, has a pretreatment filter 31 installed immediately after it.
It communicates with the second air passage 29 via the dust collector 25 and the deodorizing filter 26.

In this embodiment, the indoor air taken into the air purifier 20 through the first air intake port 22 and the second air intake port 30 is pressurized by the blower 27 and blown downward from the air outlet 23. The indoor space outside the purifier 20 is the first
An air curtain 32 is formed which is divided into a first space IA on the side where the air intake port 22 is located and a second space 19B on the side where the second air intake port 30 is located. This air curtain airflow is separated near the floor surface 1b, into a first space IA and a second space 1B.
The rising air currents are 33 and 34, respectively. 1st space I
Dust particles containing cigarette smoke generated within A are carried upward by this rising air current 33 and flow into the air purifying device 20 through the first air intake port 22. After the flowing dust-containing air has coarse dust removed by the pretreatment filter 24 , it passes through the first air passage 28 and reaches the dust collector 25 . The dust particles including cigarette smoke are removed by the dust collector 25, and the air is deodorized and cleaned by the deodorizing filter 26, and then the air is passed to the second filter.
The air flows into the air passage 29. The second air passage 29 is the blower 2
Due to the suction action of 7, there is a negative pressure with respect to the outside air. For this reason, the second air intake port 3 facing the second air passage 29
Air in the second space 1B also flows into the air purifier 20 from the pretreatment filter 31 from the pretreatment filter 31. Second air passage 2
The air flowing into the air outlet 9 is pressurized by the blower 27 and sent to the air outlet 23 .

In this way, the air purifier 20 has the first air intake port 2
2 and the action of blowing out the indoor air taken in from the second air intake port 30 from the air outlet 23 to form the air curtain 32 are repeated to maintain the indoor space separated into the first space 1A and the second space IB. .

Here, since the first space IA and the second space IB are separated by the air curtain 32, the air in the two spaces does not mix, and the air in the first space IA flowing into the first air intake port 22 does not mix. After the dust-containing air is purified in the air purifier 20, it is released as an air curtain airflow.
By making the space IA a smoking space, it is possible to prevent the air in the second space IB from being contaminated during smoking.

That is, according to this embodiment, when providing a smoking space in a part of the room, the wall material 13 as in the conventional example shown in FIG. 14 is not required, and the area to be purified by the air purifier 20 is the first space. Since it is limited to only the IA and the processing air volume is small, installation costs can be reduced.In addition, by installing the air purifier 20 on the ceiling as in this embodiment,
Even if the smoker 11 and the non-smoker 12 stay in the first space IA at the same time, the cigarette smoke moves upward together with the rising air current 33 generated in the first space IA, so the non-smoker 12 stays in the first space IA at the same time.
It does not become an obstacle to 2.

Furthermore, in this embodiment, since the second air intake port 30 is provided to take in the air in the second space 1B into the second air passage 29, the amount of air blown from the air outlet 23 is equal to the amount of air blown out from the first air intake port 29. This is the sum of the amount of air taken in from the second air intake port 30 and the amount of air taken in from the second air intake port 30. Of these, the second air intake port 3
The air taken in from 0 has a dust collection capacity 25 and a deodorizing filter 26.
The air flows directly into the second air passage 29 without passing through the dust collector 2.
5 and deodorizing filter 26. Since there is no pressure loss caused by this, a large amount of air can be introduced with less power than when air is taken only from the first air intake port 22, and therefore a stronger air curtain 32 can be formed.

As shown in FIG.
5 may be provided. By controlling the amount of air taken in from the second space IB using the air volume adjustment plate 35, the amount of air blown out from the air outlet 23 changes, and the height at which the air curtain 32 disappears changes accordingly. do. Therefore, in this embodiment, it is possible to generate an air curtain airflow that is adapted to the height of the indoor space in which the air purifier 20 is installed. The optimum blowing speed of the air curtain varies depending on the height of the indoor space, but for example, if the distance from the air outlet 23 to the floor is 2.5 m, the optimum blowing speed of the air curtain is 1.0 to 3.0 m.
An air flow condition as shown in Fig. 1.2 can be obtained at an outlet wind speed of /s.

Further, in order to exhibit an effective air curtain effect, the blowing direction of the air blowing outlet 23 may be made variable as shown in FIG. In FIG. 3(a), the air outlet 23 is separate,
An example in which the blowing direction is made variable by rotating around the shaft 36, and (b) is an example in which the blowing direction is made variable by rotating the wind direction adjusting plate 37 provided in the air outlet 23. The plate 37 can also be used to control the blowing air speed.

0B has an air outlet 23B with an L-shaped planar shape,
It is a two-way blowout type that blows out air curtain airflow along two adjacent sides of the first air blowout port 22. By making these two types of air purifiers 20A and 20B into units and combining these units according to the way the indoor space is divided by the air curtain, the size of the first space that is the smoking room, etc., it is possible to meet various demands. I can comply. FIG. 6 is a plan view showing an example of how the indoor space is divided using the air purifiers shown in FIGS. 4 and 5, and FIG. 7 is a perspective view of the ceiling portion of the first space IA in FIG. 6. In this example, a first space IA, which serves as a smoking room, is provided in a corner of the room.
Space IA includes air outlet 23A of one-way outlet unit 20A and air outlet 2 of two-way outlet unit 20B.
It is formed directly below the ceiling section separated by 3B.

It is formed directly under the ceiling part that is partitioned by the air outlet 23B, and the indoor space is transformed into the first space IA with only the air curtain.
and a second space IB.

FIG. 10 is a plan view showing a third example of the division style, and FIG. 11 is a perspective view of the ceiling part in FIG. 10. In this example,
The air outlets 23A of the one-way outlet unit IA are arranged in a horizontal line between the partition walls 10.1d in the room, and the air curtain airflow blown out from the unit IA transforms the indoor space into the first space IA.
and a second space IB.

In each of the above embodiments, the air purifier is installed on the ceiling and an air curtain is formed by the downward blowing airflow. However, in some cases, the air purifier 20 may be installed as shown in FIG. An air curtain 38 is installed horizontally along the wall surface 1e on one side of the room, and divides the indoor space into a first space IA and a second space IB by a horizontal blowout airflow from the air outlet 23 toward the opposite wall surface 1f. can be formed.

This air curtain airflow separates near the opposite wall surface 1f, and the lateral airflow flows through the first space IA and the second space IB toward the first air intake port 22 and the second air intake port 30 of the air purifier 20, respectively. It becomes 39.40.

Therefore, if the smoker 11 is on the leeward side of the +4it countercurrent 39 than the non-smoker 1z in the first space IA, the cigarette smoke generated by the smoker 11 will be non-Ily! It does not become an obstacle for Smoker 12.

〔Effect of the invention〕

According to the present invention, an air curtain that divides an indoor space into two is formed by the exhaust air of an air purifier, and dust particles generated in one of the divided spaces are removed by a dust collector in the air purifier. Because the plants were used to release purified air as an air curtain airflow, a part of the indoor space could be used as a smoking room by simply installing an air purification device with a relatively low processing volume and without using partition walls. By providing a space with an air purifying device suitable for smoking, indoor air pollution due to smoking can be prevented, and equipment costs can be reduced.

Moreover, since the space serving as the smoking room is open, it is easy for smokers to use it and does not hinder the use of indoor space.
