Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifying apparatus for purifying air pollution in a limited area, and more particularly to an air purifying apparatus suitable for purifying air pollution caused by smoking in a smoking room or a smoking place. It is about.

[0002]

2. Description of the Related Art As a device for purifying air polluted with smoke or odor, there is an air purifier having a filter and a blower. What is generally well known is that the processing air volume for purifying the air in the entire room is relatively large.
For purifying local air pollution in a limited space such as a smoking room or a smoking place set in a corner of an office or a station, an air purifier with a small processing air volume has been developed. For example, JP-A-9-121947 and JP-A-8-112145 disclose tables having an air cleaning function. Basically, these are configured with an air purifier in the table body to purify polluted air in a limited space around the table, and to locally treat a limited space such as a smoking room or a smoking place. Suitable for purification of air pollution.

In the former of the publications described above, a suction port 72 for an air purifier is provided at the center of a table top plate 71 of a table body 70 as shown in FIG.
Is covered with a shielding plate 73, the surrounding air is sucked in a form along the table surface from between the shielding plate 73 and the table top plate 71, and the purified air is blown out from one side of the table body 70. I have. On the other hand, in the latter, as shown in FIG. 39, a suction port 72 of an air purifier is provided in the center of a table top plate 71 of a table main body 70, and the air sucked from the suction port 72 is subjected to a purification process. The air is sent to an air blowing portion 74 provided on the table top plate 71, and is blown from the upper portion of the air blowing portion 74 toward the suction port 72.

[0004]

SUMMARY OF THE INVENTION In the above-mentioned conventional table having an air purifying function, Japanese Patent Laid-Open No. 9-1219 discloses a method.
No. 47, the table top 71
Is formed toward the suction port 72 in a direction along
Since the flow velocity of the airflow at the portion in contact with the table top 71 is attenuated and its suction action is extremely weak, and the air is sucked in a limited range between the shielding plate 73 and the table top 71, the treatment of the polluted air is performed. There is a problem that the range is narrow.
Further, since the suction effect does not work above the shield plate 73 by the shield plate 73, when smoking in a standing posture, smoke smoked by the smoker and smoke emitted from cigarettes in hand can be sucked. However, if the users face each other and use the cigarette smoke, it may not be easy to use.

[0005] In this respect, Japanese Unexamined Patent Application Publication No. Hei 8-112145 discloses that an air flow is blown down from an upper portion of an air blowing portion 74 toward a suction port 72 on a table top plate 71.
Since the tobacco smoke is attracted and sucked into the suction port 72, the suction action extends to above the table top plate 71, and the above-mentioned problem does not occur much even when smoking in a standing posture. However, since the airflow from the air blowing part 74 is blown down near the user's ear, the user has to use it while feeling a tactile noise, which is not a very good feeling of use. Further, in a place where there is an outside wind, the airflow to be blown down is disturbed and comes off from the suction port 72, so that it is difficult to effectively suck the cigarette smoke. Further, in any of the above-described tables having an air purifying function, since the suction port 72 is opened on the plane of the table top plate 71, a drink or the like is placed on the table top plate 71, so that careless care is required. If it falls down, the suction port 72
There is also a problem that a drink may enter the inside of the device and cause a failure of electric components.

An object of the present invention is to provide an air purifying apparatus which has a wide range of sucking air for purifying treatment and has excellent usability, and an air purifying apparatus which does not cause trouble due to overflowing drinks and the like. It is an object of the present invention to provide an air purifying device capable of more effectively sucking and purifying tobacco smoke accompanying smoking, and to improve the usability and function of the air purifying device.

Embodiments of the present invention will now be described with reference to the drawings. Embodiment 1 FIG. The air purifying apparatus according to the first embodiment shown in FIGS. 1 to 4 has a mechanism for purifying air by continuously sucking air around the box 1 into the box 1 having a base structure. The air purifier 2 is composed of the air purifier 2 and has been devised so as to be able to cope with various matters relating to smoking. The air purifier 2 can be installed in a smoking room, a part of a station platform or a part of a company building. This device is installed in a smoking area set in the area, and purifies polluted air generated in the limited space.

The basic structure of the air purifier 2 is as follows: a blower 3 for forming a unidirectional air flow in a series of ventilation paths for taking in the air to be processed and sending it out again; The filter 4 as a main body of a purifying treatment function is incorporated. The ventilation passage is formed in the box 1, and the suction port 5 for taking in the air to be treated is opened upward at the center of the top surface 6 of the box 1. A plurality of outlets 7 which are outlets of the ventilation path are provided at a lower portion or a bottom surface of a side surface of the box 1. The blower 3 is incorporated on the side of the outlet 7 of the ventilation path, and forms an airflow from the suction port 5 toward the outlet 7 in the ventilation path. In this embodiment, a turbo fan is adopted as the blower 3, but another centrifugal blower such as a sirocco fan or a radial fan may be used. The filter 4 of the present embodiment includes a pre-filter 8 for collecting relatively large particles, and an electric precipitator 9 for collecting relatively fine particles.
And a deodorizing filter 10 for absorbing gaseous odor components
And a pre-filter 8, an electric dust collector 9,
A pre-filter 8 is removably mounted in the ventilation path between the suction port 5 and the suction port of the blower 3 in the order of the deodorizing filter 10 so as to cross the ventilation path so as to be on the upstream side.

The box 1 has a structure as an outer shell of the air purifier 2, and is provided with a table 11 on the top surface 6 and is configured as a cabinet. That is, the height of the upper surface of the table 11 of the box 1 from the floor surface up to the table surface 12 is:
It is formed at a height where people can move their hands, put their elbows, and place objects without any discomfort while standing. The table 11 projects outwardly of the box 1 on the top surface 6 of the box 1 in a flange shape, and the table surface 12 is capable of holding an ashtray, a drink, a book or baggage. The height of the box 1 depends on the physique of the user, but is 800 based on the average height of a Japanese adult.
It is set to about mm to 1000 mm. A wheel 13 with a stopper is attached to the bottom of the box 1,
The whole apparatus can be freely moved to a required place and can be held at a predetermined position by a stopper.

On the top surface 6 of the box 1, there is provided a suction dome 15 having a main suction port 14 surrounding the outer periphery of the suction port 5 and opening upward at a position higher than the suction port 5.
The upper end of the suction dome 15 is finished in an R shape by curling over the entire circumference. A protective lid 1 made of punched metal or mesh for preventing foreign matter from entering the main suction port 14 opened at the upper end of the suction dome 15.
6 is mounted. The inside of the suction dome 15 is a hollow ventilation path 17, and the main suction port 14 and the suction port 5 of the box 1 are in a positional relationship vertically facing each other. Suction dome 15
Height may be set appropriately in accordance with the height of the box 1 to prospect the 100Mm～500mm.

The position of the pre-filter 8 may be between the protective lid 16 and the electrostatic precipitator 9, and the position of the deodorizing filter 10 may be a ventilation path between the outlet of the blower 3 and the outlet 7. .

If this air purifying device is installed in a smoking room or a smoking place and the blower 3 is operated, a suction action works above the suction dome 15 and around the table surface 12. The surrounding air sucked from the main suction port 14 passes through the ventilation path 17 in the suction dome 15 and enters the air cleaner 2 from the suction port 5 of the box 1. The air sucked from the suction port 5 passes through the filter 4 and is sucked into the blower 3, and is blown out from the plurality of outlets 7 connected to the discharge ports of the blower 3. When the air sucked into the air purifier 2 passes through the filter 4, relatively large particles are first collected by the pre-filter 8, and then relatively fine particles are collected by the electric precipitator 9. A gaseous odor component is adsorbed by the deodorizing filter 10 and purified.

The feature of this air purifying device is that a range in which the suction operation by the blower 3 works (1 m in which tobacco smoke and the like can be sucked).
The area where an air flow of about / s is formed is widened by the presence of the suction dome 15. FIG. 2 shows the measurement results obtained when the height from the floor surface to the table surface 12 was 1000 mm and the height of the suction dome 15 was 250 mm.
Indicated by The range in which the suction action works when there is no suction dome 15 is the range surrounded by the solid line A in FIG. 2, and when the suction dome 15 is provided, the range in which the suction action works is as follows.
This is a range surrounded by a broken line B in FIG. With the suction dome 15 moving the suction port 5 substantially upward by 250 mm, the range in which the suction action works in the vertical direction is 25
It goes without saying that the height is increased by 0 mm, but the range in which the suction action in the horizontal direction works is also enlarged as shown in the figure.

This is because there is no wall surface on the plane where the main suction port 14 of the suction dome 15 opens, and there is no fixed flow velocity condition such as the wall surface in the suction airflow to the main suction port 14 from a substantially horizontal direction. This is because the side is not forcibly decelerated. When the suction dome 15 is not provided, the suction airflow directed substantially horizontally to the suction port 5 is restrained by the shear stress due to the presence of the wall surface such as the table surface 12 or the top surface 6 of the box body 1. Thus, the working range of the suction action becomes narrow. In addition, the force for inhaling cigarette smoke and the like also extends to a space below a plane including the main suction port 14. Main suction port 1
4 is inversely proportional to the square of the distance from the main suction port 14, but since the distance from the main suction port 14 is short, the tobacco smoke is also applied to the table surface 12 below the plane including the main suction port 14. The force to inhale etc. will work. Increasing the opening area of the main suction port 14 can also widen the range in which the horizontal suction action works.

Therefore, when this air purifying device is used as a smoking place, for example, the above-mentioned box 1 and suction dome 1
According to the height dimension of No. 5, the vertical suction area of tobacco smoke and the like is from 1000 mm above the floor to 75 mm above it.
It is about 0 mm above, and for example, a smoker with a height of 1 m and 80 cm is standing beside the table 11 and smokes cigarettes blown out of his mouth and smoke coming out of his hand can be sucked through the main suction port 14 and purified. It is possible. Of course, the smoke coming out of the cigarette in the ashtray placed on the table surface 12 can also be sucked in from the main suction port 14 and purified. With this air purifying device, even if the smoker smokes at the opposing position of the table 11 by the above-described function, it does not cause an unpleasant sensation such as spraying the cigarette smoke blown out by the facing persons, and is good. Sensation is obtained. In addition, since the main suction port 14 is provided at the upper end of the suction dome 15, even if the table surface 12 overflows with drinks, etc.
Therefore, it is possible to prevent electric components from being broken due to intrusion of overflowing drinks and the like without entering the air purification device.

The shape of the suction dome 15 is not limited to a truncated cone or a pyramid, but may be a flared cone as shown in FIG. It may be. Also, as for the shapes of the box 1 and the table surface 12, a square frame shape, a round frame shape, an elliptical frame shape, or the like can be appropriately adopted to take a design configuration.

The opening 40 is provided with a baffle member 28 having an isosceles triangular cross section in the opening 40 with its bottom side protruding into the chamber 27. The baffle surface 33 of the baffle member 28 and the opening of the opening 40 are provided. The slit outlet 29 may be formed between the edge and the edge. According to the configuration of the downdraft airflow generation unit 26,
Since the slit outlet 29 is close to the wind guide surface 33, the wall jet 36 is smoothly formed. The air guide member 28 may have a solid structure or a hollow structure, or may be formed of a flat plate. However, since the air guide surface 33 is liable to be stained on its surface and lose its smoothness. It is desirable that the surface be formed of a material that is not easily stained or coated.

Here, the function of the downdraft airflow generating unit 26 will be clarified by comparing the downdraft airflow 37 generated by the downdraft airflow generating unit 26 with a general two-dimensional jet. FIG. 18A is a cross-sectional view showing a structure of a two-dimensional jet 42 blown out from a single slit 41, and FIG. It is sectional drawing which showed the structure of the jet 44 which was blown off. For comparison, it is assumed that both are blown out at the initial speed of U0, and the blowout air amount and the sum of the blowout widths are the same. It is known that the two-dimensional jet 42 blown out from the slit 41 in FIG. 18A spreads at a constant deployment angle while entraining the surrounding gas. When the main suction port 14 of the suction dome 15 is provided below the distance h from the slit 41, the maximum speed Uma is at the position of the main suction port 14.
x is attenuated and smaller than the initial speed U0.
Rajartnam (Jet, Morikita Publishing, p. 22, 19)
80), Umax = 3.50U0 (h / 1)-
It becomes a value of ^1/2 .

On the other hand, when the air is blown out from the two slits 43 by the wedge-shaped air guiding member 28 in FIG. In the wall jet 36, the surrounding gas is limited to the free shear surface not facing the wall surface, so that it moves to the wedge-shaped apex (ridgeline 34) while maintaining a relatively stable state. Can be. Further, since the apex angle is configured as acute as possible, the two wall jets 36 smoothly merge at the apex, and the new jet origin having a width of 2 l is moved to the apex of the baffle member 28 as if it were a new one. Width from vertex to 2
The combined jets 44 of l. Assuming that the height from the slit 43 to the apex of the wind guide member 28 is h0, the maximum velocity U at the point from the slit 43 to h using the above-described formula.
max is, 3.50U0 {(h-h0) / 1} - 1/2 , and the single two-dimensional jet flow blown out from the slit 43 4
It is clearly larger than 2. In other words, the main suction port 14
In order to set the maximum velocity of the jet 44 at a point to a certain value, a smaller initial flow velocity is required than in the case of the two-dimensional jet 42 from the slit 41 having a normal width of 2 l.

As described above, the provision of the downflow airflow generating section 26 having the structure as shown in the fifth embodiment allows the low speed and stable downflow airflow 37 to be supplied to the main suction port 14.
, The both sides of the table surface 12 can be shut off, and the smoke of the cigarette blown out by the smoker can be prevented from reaching the opposite side of the table surface 12.

The airflow guide 45 is formed in a flat plate shape, and is provided so as to protrude substantially parallel to the wind guide surface 33 along an edge of the slit outlet 29 facing the wind guide surface 33 of the wind guide member 28. The length of the airflow guide 45 is set equal to or longer than the length of the slit outlet 29 in the longitudinal direction.

The direction of the jet blown out from the slit outlet 29 by such an airflow guide 45 is adjusted by the air guide member 2.
8, the direction of the flow is more in line with the wind guide surface 33, so that a more stable wall jet 36 can be formed, and
7 also has a more stable airflow. The airflow guide 45 is shown in FIG.
As shown in FIG. 3, the same function can be achieved even if it is configured to protrude into the inside of the chamber 27. Other configurations and functions are the same as those of the fifth embodiment. Note that the seventh embodiment can be applied to the sixth embodiment.
