More specifically, the present invention is capable of effectively suppressing allergic reactions caused by aerosols in the air such as pollen, cigarette smoke, dust, and mites while sleeping, etc. It's about the booth.

[0002]

2. Description of the Related Art In recent years, the increase in the number of allergic patients who are sick due to an allergic reaction due to aerosols in the air such as pollen, cigarette smoke, mites, dust, etc. and which are impairing a healthy life is socially significant. It's a problem. Thus, allergic diseases caused by aerosols in the air have a serious influence especially on infants, the elderly, and patients suffering from other diseases, and even in normal adults, these allergic diseases affect daily life. It is a big obstacle. The allergic reaction affects various symptoms such as itching and pain in the nose and eyes, coughing, loss of appetite, insomnia, autonomic imbalance, and depression.

Under such circumstances, treatments by administration of drugs and various treatments aiming at an immune enhancing effect have been tried, but a decisively effective means has not been found yet. Is the reality. In addition to such treatment, measures such as the use of masks and glasses to prevent contact with aerosols in the air, and the installation of air purifiers at home are also being considered, and dust-proof Various tools and devices are commercially available.

However, in these conventional measures,
The contact suppression effect of the aerosol in the air is not sufficient,
For example, there is still no realization of aerosol protection that is more effective, has less resistance during use, and can be used comfortably and comfortably while sleeping. On the other hand, of course, in order to eliminate the influence of the aerosol, it is conceivable to improve the cleanness of the indoor air and maintain the environment like a so-called clean room. However, such a clean room requires a large amount of cost and is not practical to use in a home or the like. For example, aseptic ICU has been used as hospital equipment so far.
As a unit, etc., a clean area separated from the surrounding area is provided, and clean air is supplied only to this area. However, this equipment is for forming a sterile state, is large-scale as a hospital equipment, and is extremely expensive. Therefore, it cannot be used easily at home.

In fact, such a clean room has not been generalized so far. The idea and even its embodiment have not been tried. The present invention has been made in view of the circumstances as described above, and solves the problems of conventional methods and equipment, suppresses allergic reactions caused by aerosols in the air, and gives health and comfort to many patients. Therefore, it is an object of the present invention to provide a new clean space that can be used at home at low cost and easily and an air supply means therefor.

[0006]

In order to solve the above-mentioned problems, the present invention has a clean air supply section through a filter and a blowing section from above or in the vicinity of this clean air. Provided is a personal clean booth characterized in that a clean air space is surrounded by a sheet, and the sheet is supported by a foldable frame body.

Further, according to the present invention, the seat is supported by a lightweight assembly frame or the like which can be contracted and expanded by a hinge or a plug-in connection, and a clean air supply section and a blow section are connected by a seat duct through a filter. What is done is that the entrance / exit of the seat surrounding the clean air space is opened / closed by a fastener or the seats are stacked and opened, and any part or all of the seat is detachable and / or expandable / contractible. This is also the case. Also, since allergic attacks are severe at the beginning of bedtime and before waking in the early morning, the clean booth of the present invention is installed around the bed and the clean air supply unit that can raise and lower to guide clean air blown overhead. The arrangement and the like are also in that form.

The specific structure will be described below as an embodiment.

In any of the above examples, the clean booth having the foldable frame body of the present invention is not limited, but by making it foldable,
It can be stored and stored compactly during storage and transportation, and does not take up unnecessary space. When used, it can be assembled by one person. When attaching the seat (2) to such a lightweight frame body as illustrated in FIG. 1, various modes are adopted. For example, as illustrated in FIG. 6, the ceiling frame (4) has a curtain rail structure,
The sheet (2) is composed of a ceiling sheet (21) and a curtain sheet (22), and the ceiling sheet (21) includes:
An outer hanging part (211) and an inner hanging part (212) are arranged with respect to the ceiling frame (4), a curtain sheet (22) is arranged between them, and the curtain sheet (22) is arranged on the liner hook (9). 22) is attached.

Since the clean air space (3) is kept at a positive pressure, the inner hanging part (212) of the ceiling sheet (21) can be brought into close contact with the curtain sheet (22). As a means for further suppressing air leakage, for example, as shown in FIG. 7, a hanging piece (401) is extended to the ceiling frame (4), and the hanging piece (401) contacts the curtain sheet (22). You may do it.

Alternatively, as illustrated in FIG. 8, the seat portion extends further above the portion where the curtain sheet (22) is fastened to the liner hook (9), and the seat extension portion (402) serves as a ceiling frame ( You may make it contact | abut to 4). In any case, the ceiling sheet (21) can be attached to the ceiling frame (4) by a locking means such as a hook.

By adopting such a curtain system, mounting and withdrawal can be facilitated. When such a system is adopted, as shown in FIG. 9, the curtain sheet (2
2) is a coil spring (9) as a liner hook (9).
You may make it attach to what has 1). As a result, the curtain sheet (22) can be attached more stably,
And operable.

Of course, instead of the method of locking the curtain sheet (22) to the liner hook (9), another structure can be adopted. For example, as illustrated in FIG. 10, a sticking method using a magic tape (10) or the like may be adopted. Further, there is no particular limitation on the connection structure between the blowout portion (7) and the supply portion (8) of clean air, and the arrangement thereof is also not limited. Regarding the clean air supply unit (8), the fan and the filter device may be integrated or may be provided separately. The filter device may also be arranged in the outlet (7).

As shown in FIG. 11, the clean air supply unit (8) containing the filter device and the blowing unit (6) are connected by a sheet duct (11) made of a resin sheet, and the sheet duct (11) is connected. The sheet may be formed separately from the sheet (2) and may be detachably attached to the sheet (2), or may be integrally fixed by welding or the like.
In the case of a separate body, as illustrated in FIG. 12, the seat duct (11) is previously attached to the support plate (12), and both ends of the support plate (12) are locked to the ceiling frame (4). However, the end supply port (13) of the sheet duct (11) may be arranged through a predetermined hole from the inside of the curtain sheet (22), or may be arranged by an external attachment method.

In the former inside arrangement, the holes in the curtain sheet (22) preferably have a reinforcing and sealing ring structure. The blowout part (7) may be provided with a mesh-shaped dispersion plate, a filter, or the like. As shown in FIG. 1, the entrance / exit of the clean air space (3) formed by the seat (2) has an opening / closing structure by an overlapping part, or an opening / closing structure by a fastener (5), and an optional attaching / detaching part. Alternatively, a part or all of the fastener may be detachable by means of a fastener having good airtightness, a magic tape or the like.

The predetermined clean air space (3) formed by the sheet (2) may be freely formed by a winding method, a winding method, a sliding method (single opening, double opening), a bellows folding method, or the like. In the clean booth of the present invention, the clean air from the blowout part (7) is circulated as a one-way flow from above or near the head to the outlet under the foot, or as a diffusion flow in multiple directions. .. At this time, the atmospheric pressure in the booth is also referred to as positive pressure.

The wind speed of clean air can be, for example, about 0.1 m / sec or less while sleeping, and the pressure in the booth can be about 0.1 to 0.5 mmH ₂ O. By this condition, it is possible to prevent external dirty air from flowing back into the clean air space (3) and maintain the internal clean state. For such wind speed and pressure condition, a control mechanism that can change the mode at any time automatically or manually can be provided. For example, in the general mode, it is cleaned in about 30 minutes before sleep, and in the sleep mode, it is kept clean during sleep. It can also be controlled by the air conditioning function.

Further, by making the cover used for the bed to suppress dust generation, the cleanliness inside the booth can be further kept good. In order to reduce the user's psychological resistance, a curtain may be attached together with the seat (2) to block the external view. The sheet (2) itself may be colored or patterned.

For example, the above clean booth is
It can be used in any home as long as it has a power supply of 100 V, can maintain the cleanliness of 10 to 100 times that of a general home air purifier, and can be provided as an extremely inexpensive one. Of course, the clean booth is not limited to the bed (1) as in the above example, and the clean booth of the present invention may be installed around other furniture such as a study desk or a table. By improving the lighting and other functions, it can be used as a comfortable space that can be assembled and installed at any time for home use.

A futon may be laid on the floor. In this case, a floor sheet may be placed and fixed. of course,
In addition to home, it may be set at school or other public facilities as needed. Further, with regard to the personal clean booth of the present invention, noise inside and outside the booth can be suppressed to an extremely low level by devising a fan or the like.

In the clean air space (3) which is separated from the outside by the sheet (2) so as to surround the bed (1), the blowing portion (7) is expanded or contracted by a sheet made of, for example, transparent resin or the like. It is also possible to dispose a streamer (10) for blowing clean air that can be raised and lowered. By this blowoff, the clean air can be preferentially guided to the upper part of the head or the vicinity thereof. Therefore, for example, it is possible to remove dust generated by lifting the futon at bedtime and dropping the futon in a shorter time for cleaning.

For example, the cleaning effect of the clean booth of the present invention as described above will be described more specifically. In the clean booth provided around the bed, when a person goes in and out of the futon, particles of 0.5 μm are added. When entering the futon, the dust concentration (the concentration at the head when the lid mouth of the futon is lifted by 30 cm and dropped) rapidly increases, but the clean air supply / blowing speed is 0.293 m /
When it is set to s, it takes about 6 minutes and 0.233 m /
When it is set to s, it can be cleaned up to the cleanliness of class 1000 in about 9 minutes. On the other hand, when the clean booth of the present invention is not used, it is rarely cleaned beyond the level of class 10,000.

As described above, the clean booth of the present invention realizes an extremely excellent cleaning effect. In any case,
It goes without saying that the present invention can be variously modified in details.
