By organically integrating the suction power of a household ventilation device already installed in a multi-unit dwelling with the structural idle space of the vertical plane existing between the lower and upper sections of the entrance, it implements a powerful entrance dust collection function without the need for a separate independent device. The system of the present invention comprehensively provides an entrance-dedicated connection duct, a flow path switching damper, an air curtain formed by a suction grille and an air injection nozzle, a filterless structure based on a cyclone chamber, UV-C sterilization, autonomous control based on air quality and image recognition, seasonal control linked with heat exchange elements, prefabricated modularization, integration of a common exhaust shaft, and a fire-resistant and backflow prevention safety structure. Based on universal principles of infrastructure integration, flow concentration, closed-loop airflow, removal of consumables, redundant use of space, and energy recovery integration, the present invention simultaneously overcomes the inherent limitations of conventional independent air shower booths and filter-based air purifiers.

Description

Entrance Dust Collection System Integrated with Residential Ventilation System The present invention relates to indoor air quality management technology for multi-unit housing, and more specifically, to a unit ventilation system-linked entrance dust collection system that combines a unit ventilation device (Energy Recovery Ventilator; ERV or Heat Recovery Ventilator; HRV) already installed in a unit of multi-unit housing, including apartments, with a structural clearance space of a vertical surface (Riser) that inevitably exists between the lower part of the entrance where shoes are removed and the upper part of the indoor floor, thereby powerfully removing foreign substances, fine dust, viruses, and pathogenic microorganisms in the entrance area without the addition of a separate independent dust collection device, and discharging them to the outside without spreading into the indoor space. In the living spaces of modern urban dwellers, the main route for external pollutants, such as fine dust, yellow dust, pathogenic microorganisms, and pollen, to enter indoors is the entrance. When residents return home from an outing, large amounts of pollutants adhere to shoe soles, clothing surfaces, umbrellas, and pet hair; these pollutants then spread indoors through airflow disturbances and physical contact as residents pass through the entrance. Particularly in high-rise apartment buildings located in large cities, a phenomenon is observed where pollutants temporarily remain in the confined space of the elevator, then float again in front of the apartment entrance, and are swept into the interior the moment the front door opens. To address these issues, conventional methods have proposed installing a separate booth-type air shower unit in the entrance area. However, this approach is a scaled-down version of semiconductor cleanroom air shower technology for residential use; it has disadvantages such as significant loss of floor space due to the need to independently provide a structure surrounding all four sides, a blower, a filter, and a control circuit, as well as high initial investment costs per household and a heavy maintenance burden resulting from the mandatory periodic replacement of filters. Additionally, a method has been proposed to incorporate a small blower beneath a floor mat or step plate to suck up foreign matter from shoe soles; however, this method has limitations in terms of hygiene because the size and output of the blower are limited, making it difficult to achieve effective dust collection efficiency, and the foreign matter trapped beneath the mat ultimately requires manual collection by the user. A method of purifying airborne dust by installing a small air purifier or plasma ion generator on the entrance ceiling has also been proposed; however, this method is ineffective against large particulate foreign matter attached to shoes, and since the structure involves the purified air being recirculated indoors, it fails to expel pollutants to the outside, thus failing to serve as a fundamental solution. Meanwhile, in accordance with the Building Act or the construction company's standard specifications, unit ventilation systems are installed as standard in recently constructed multi-unit dwellings. These ventilation systems perform the basic function of exhausting polluted indoor air to the outside and introducing fresh outdoor air into the interior, as well as the function of recovering energy through the exchange of sensible and latent heat. However, the current general construction practice is to branch the exhaust lines of these ventilation systems only to major living spaces such as the kitchen, living room, and bedroom, while excluding the entrance area from the branching of the exhaust lines. Furthermore, due to the geometric structure of the entrance, a step difference of typically 100mm to 250mm is formed between the lower section where shoes are removed and the upper section, which is the indoor floor. Behind the vertical surface constituting this step difference, there exists an empty space that is structurally unused except for finishing materials. Thus, no prior examples have been identified in which a new function of dust collection at the entrance was created by organically integrating two infrastructural assets inherent in multi-unit dwellings: the suction power of the unit ventilation system and the spatial emptiness of the vertical surface at the entrance. Therefore, there has been a continuously increasing technical demand for entrance dust collection systems that can simultaneously achieve low construction burden, zero dedicated floor area, elimination of filter replacement burden, and minimization of seasonal energy loss by combining the spare suction power of existing household ventilation systems with the idle space on the vertical surface of the entrance without the installation of additional independent devices.
