装置を備えた椅子に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is provided with an artificial tornado-type local exhaust device that collects and cleans air containing soot, dust, etc., which is mainly used indoors. Regarding the chair.
従来の椅子は、単に人が腰を掛けて休む機能しかない。

愉快になっていた。Conventional chairs merely have the function of allowing a person to sit and rest.
However, recently, a chair installed in a place where many people gather, such as a theater, has been developed in which conditioned air is emitted from the backrest. This is for the purpose of air-conditioning a large space by intensively air-conditioning the floor surface on which a person sits, thereby saving air-conditioning energy. Therefore, since it is not intended to block the space by giving the air coming out of the chair an air curtain function, the blowing speed and volume of the blowing air are designed to be extremely small, and the usage target is limited. In such a traditional chair, restaurants, restaurants,
At the smoking seats of general offices, trains, airplanes, etc., cigarette smoke flows out of these smoking seats. Further, even in a seat where smoke or smell such as roasted meat is generated, in the conventional chair, smoke or smell is leaked to the surroundings, causing annoyance to others, and it is also unpleasant for the person himself / herself.
そこで、これらの不都合を解消するために、本出願人

の上方部にエアーカーテンを形成するものである。Then, in order to eliminate these inconveniences, the present applicant has developed a chair with an air curtain, an air purifier, and a chair with an air curtain. This chair with an air curtain (see Japanese Patent Application No. 63-9159) is provided with a chair body having an air outlet in the upper part and an air suction port in the lower part, and a blower inside the chair body. Air is sucked from the air suction port of the chair body through the blower and discharged from the air outlet to form an air curtain in the upper portion of the chair body.

天井部分などから外部巻込風量以上の風量を排気して常
に内部を負圧に保てば、煙草の煙などは周囲に流出せず
他人に迷惑が掛からない。In this conventional chair with an air curtain, the air curtain blown up from the upper part of the chair body entrains the air inside and outside, and since the air volume increases, the smoke from the chair body also mixes into the air curtain. Is
Exhaust more than the amount of externally entrained air from the ceiling, etc., and always maintain a negative pressure inside, smoke from cigarettes will not flow out to the surroundings and will not disturb others.

In order to eliminate these problems, some of the air that forms the air curtain has been allowed to escape, and an air purifier that removes tobacco smoke, etc. is a chair with an air purifier and an air curtain (Japanese Patent Application No. 63-192762). See).

る。In addition, there is a local exhaust device using an artificial tornado by the present applicant (see Japanese Patent Application No. 01-111788). This device consists of an artificial tornado generating mechanism and an exhaust cleaning mechanism. In this artificial tornado generating mechanism, the back wall of a box body having an open front is formed into a spiral curved surface, and an air discharge pipe for generating an air curtain is arranged at the tip of this back wall, and further on both sides. An air suction port is provided on the wall surface. The exhaust cleaning mechanism is provided with a workbench under the box body, and the air containing dust, smoke, etc. sucked from the air suction port is made into clean air and discharged into the workbench. Therefore, smoke, dust, etc. generated on the workbench will not leak to the outside due to the air curtain formed by the air blown from the air blowing pipe, and the air curtain created by the artificial tornado generated around the axis of the air suction port. It is collected together with the air inside and sent to the workbench where it is made into clean air.

引し、その吸引された空気を空気清浄器に通して清浄空
気を得るものである。従って、発生した煙、粉塵などが
速やかに排除されず、エアーカーテン内を一定時間滞流
するのである。However, in the chair as described above, it is possible to simply prevent smoke and dust from being discharged to the outside by the air curtain, or to suck air in order to keep the inside of the air curtain in a negative pressure state and clean the sucked air with an air cleaner. It passes through a container to obtain clean air. Therefore, the generated smoke, dust, etc. are not promptly removed, and the air remains in the air curtain for a certain period of time.
また、エアーカーテン内を負圧に保つためにはどうして
も風量が大きくなり、排気用送風機の容量等が大きくな
る。Further, in order to keep the inside of the air curtain at a negative pressure, the air volume is inevitably increased, and the capacity of the exhaust blower and the like are increased.
また、上述の人工竜巻式の局所排気装置は、作業台上に
発生するばい煙、粉塵等を局所排気するものであるか
ら、椅子等にそのまま使用することができない。Further, since the artificial tornado type local exhaust device described above locally exhausts soot, dust and the like generated on the workbench, it cannot be used as it is for a chair or the like.

される。According to the chair having the artificial tornado-type local exhaust device configured as described above, the air blower for supply discharges the air from the air discharge pipe to generate the air curtain, and the smoke generated by smoking etc. while sitting on the chair body. , Dust, etc. will not go out due to the air curtain. At the same time, when air is sucked from the air suction port by the suction blower, the air flows along the spiral curved surface to form a swirling airflow, and the central part of the swirling airflow is a negative pressure region due to the suction of air from the air suction port. This negative pressure region forms a negative pressure core portion along the central portion of the swirling air current, and the centrifugal force of these swirling air currents and the negative pressure of the negative pressure core portion balance toward the air suction port. A continuous horizontal tornado is generated, and the air contaminated by the tornado is quickly eliminated. The sucked air is introduced into the chair body and cleaned by an air purifier.

平方向の人工竜巻Ｈとなる。After the supply blower 7 is turned on, when the suction blowers 16 ... Rotate at the same time or with a delay and air is sucked from the air suction ports 9 and 9, the air in the space flows along the backrest 5. Spiral back 4 on top of the backrest 5
This creates a swirling air flow. A negative pressure region is formed in the axial center of the swirling airflow by sucking air from the air suction ports 9, 9. This negative pressure area forms a negative pressure core portion D along the central portion of the swirling airflow. The centrifugal force of these swirling air currents and the centripetal force due to the negative pressure of the negative pressure core portion D are balanced,
This swirling airflow becomes a continuous horizontal artificial tornado H toward the air suction ports 9, 9.

Is drawn into the side walls 8 and 8 together with air from the air suction ports 9 and 9 provided in the side walls 8 and 8 and the holes 14 and 14 are formed.
Then, the smoke is removed by the filter 15 to become clean air, and the clean air is discharged to the outside from the discharge port 17.
このため、室内に本実施例の排気装置付椅子１を別置き

Smoke generated by smoking while sitting on the chair body,
Dust etc. does not go out due to the air curtain. At the same time, when air is sucked from the air suction port by the suction blower,
Air flows along a spiral curved surface to form a swirling airflow, and a negative pressure region is formed in the central portion of the swirling airflow by suction of air from an air suction port, and this negative pressure region is the central portion of the swirling airflow. A negative pressure core part is formed along with, the centrifugal force of the swirling air flow and the centripetal force due to the negative pressure of the negative pressure core part are balanced, and a continuous horizontal artificial tornado toward the air suction port occurs, Air contaminated by this artificial tornado is quickly eliminated. The sucked air is introduced into the chair and cleaned by an air purifier.
