JP 2001-174011 A

  In the conventional air purification apparatus, the smoke of the directly sucked cigarette is processed and exhausted indoors, and the smoke of the cigarette that cannot be sucked directly diffuses into the smoking space. In order to solve this problem, with respect to tobacco smoke that has diffused in the smoking space, the air curtain always keeps the smoking space in a negative pressure state relative to the non-smoking space. The smoke from the diffused tobacco is prevented from flowing into the non-smoking space. Here, in order to always realize a negative pressure in the smoking space with respect to the non-smoking space, the smoke of the sucked cigarette is processed by the air cleaning unit and then exhausted to the non-smoking space. However, in the conventional air purification apparatus shown in Patent Document 1, even if the cigarette smoke is directly sucked, the dust collecting filter or the electric dust collector cannot collect 100% of the dust completely. The various odor components contained cannot be completely adsorbed or decomposed even by using an activated carbon filter, photocatalyst deodorization, or the like. Furthermore, it has been found that most of the gaseous harmful substances that are harmful to human health such as carbon monoxide and nitrogen oxide contained in tobacco smoke cannot be removed. Exhausting treated air containing these dusts, odorous components and gaseous toxic substances into non-smoking spaces can be seriously harmful to human health and should be avoided.

  On the other hand, a conventional outdoor exhaust device represented by a ventilation fan can surely exhaust the smoke of the sucked tobacco to the outdoors, but the range in which the smoke of the cigarette can be directly sucked is narrow. In other words, once the smoke diffused indoors is discharged over time, it is inevitable that surrounding non-smokers inhale the diffused smoke, and it is less effective for use as a smoking countermeasure.

  The present invention has been made in order to solve the conventional problems, and exhausts cigarette smoke containing harmful substances to the outside while keeping the smoking space in a negative pressure state and using clean air in the non-smoking space. It is an object of the present invention to obtain an air purification device that prevents the smoke of cigarettes that could not be directly sucked by the air curtain generated in this way from flowing into the non-smoking space. This also reliably prevents damage to passive smoking by non-smokers.

  The present invention is an air purifying device characterized in that the smoke of cigarettes is prevented from flowing into a non-smoking space, and as its means, a blower for sucking cigarette smoke, cigarette smoke, indoor dust and the like are captured. The function of generating an air curtain using clean air on the non-smoking space side that is provided on the non-smoking space side of the box that has a suction port and an outlet, and a box that has a suction path and an air outlet. And having a structure in which contaminated air from the outlet of the air cleaning unit is directly discharged to the outdoors.

  The present invention has an effect of preventing substances that could not be processed by the air cleaning unit from staying indoors by exhausting the smoke of the directly sucked tobacco to the outdoors. Furthermore, the amount of exhaust to the outside is made larger than the amount of clean air in the non-smoking space that is sucked in to generate the air curtain that is blown from the partition, so that the smoking space is negatively pressured against the non-smoking space, and the solid wall By blowing out the air curtain from the partition, it is possible to prevent the smoke of cigarettes that could not be directly sucked out from flowing into the non-smoking space and to prevent passive smokers of non-smokers.
