Description

Air Shower Air Purifier The present invention relates to an air shower air purifier that is installed at the entrance of a building or a residential space such as an apartment, and can prevent indoor air contamination in advance by performing an air shower on a user entering through the entrance. In general, dense buildings such as houses and apartments are constantly being improved by applying various convenience features to pursue the improvement of the quality of human life, but recently, due to the deterioration of the urban environment, the air quality is deteriorating significantly. For example, as industrialization progresses and pollutants are emitted from various urban developments and factories near cities, as well as exhaust fumes from automobiles and yellow dust containing various fine dusts blowing in from China recently, the quality of indoor air in houses and apartments is deteriorating significantly due to polluted air containing foreign substances harmful to the human body. In particular, according to statistics from the World Health Organization (WHO), the number of deaths caused by air pollution approaches 6 million every year, and among them, 2.8 million are caused by indoor air, indicating that indoor air pollution causes serious problems for the human body. Consequently, users residing in houses or apartments have become highly interested in air purification methods capable of purifying indoor air in order to address the indoor air quality issues that threaten their health. Purification devices, such as air purifiers, have been disclosed as purification means for purifying and improving indoor air. However, it is difficult to expect sufficient indoor air purification efficiency with such purification devices alone, and there is a problem in that pollutants and odors introduced indoors by people returning from outdoor activities cannot be adequately controlled by existing purification devices. FIG. 1 is a perspective view showing an air shower air purifier according to one embodiment of the present invention. FIG. 2 is a side view showing an air shower air purifier according to one embodiment of the present invention. FIG. 3 is a partial enlarged view showing a second sterilization light according to one embodiment of the present invention. FIG. 4 is a block diagram showing the operating state of a control unit according to an embodiment of the present invention. FIG. 5 is a drawing showing the buried state of the main body according to one embodiment of the present invention. FIGS. 6a and 6b are drawings showing a floor cleaning unit according to an embodiment of the present invention. Hereinafter, the structure and operation of the present invention will be explained in more detail with reference to the attached drawings. In describing the present invention, terms and words used in this specification and claims must be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to describe his invention in the best way possible. Referring to FIG. 1, the air shower air purifier of the present invention comprises a main body (10) installed at an entrance of a building or house, a plurality of spray fans (20) that spray air to a user entering through the entrance, one or more object detection sensors (30) for detecting the entry of the user, an intake fan (40) for sucking in outside air containing foreign substances such as dust separated and peeled from the user's clothing, a purification unit (50) for purifying the outside air sucked in by the intake fan (40), and a control unit (60) for controlling the operation of the spray fans (20), intake fans (40), etc. The above main body (10) has an upright structure and can have an internal space (100). The above main body (10) can be mounted in an entrance. For example, the above main body (10) has a certain width and height and can be installed in a stand-like form at an entrance where a user enters and exits. In this case, it is preferable to attach a bottom plate having a width relatively larger than the width of the main body (10) to the lower part of the main body (10), thereby allowing the main body (10) to be stably maintained in an upright state on the floor surface. As another example, the main body (10) may be installed in a buried form on a selected side wall of the entrance as shown in FIG. 5. In this case, when the main body (10) has a buried structure, it is obvious that the side of the main body (10) where the injection fan (20), object detection sensor (30), and intake fan (40) are installed must be exposed at the entrance. Although the main body (10) is not shown in the drawing, one or more inspection ports that can be opened and closed are provided on a selected side so that the internal space (100) can be exposed, thereby making maintenance and management easier.
