Abstract: A hygiene management device for an entrance space is proposed. In the hygiene management device, an air discharger for discharging air toward the bottom of an entrance space operates within a predetermined angle range in an entering/exiting direction of a person, and air to be discharged through a discharge hole of the air discharger is guided to an air guide unit. A plurality of vanes are installed in a row in the air guide unit to control the direction of the air to be discharged through the discharge hole.

Abstract: A kitchen hood has a first housing and a second housing that slides into and out of the first housing to adjust a length of the kitchen hood. The first housing has a fan to suction air, an outlet, and an air quality sensor assembly to continuously detect air quality in a kitchen. The second housing has an inlet and suction grill through which air is suctioned, a steam cleaning assembly to automatically steam clean an interior of the kitchen hood, and a height sensing assembly to sense a height of cookware seated on a cooktop surface below the second housing. The kitchen hood may be lengthened or shortened based on the sensed height of the cookware, and a speed of the fan and the height of the kitchen hood may be automatically adjusted based on detections by the air quality sensor assembly.

Abstract: A hygiene management device for an entrance hall and a control method of the same are proposed. The hygiene management device may be installed in the space of the entrance hall, and when the opening of an entrance door is detected, air is discharged toward the entrance door by tilting an air discharger toward the entrance door, and when the closing of the entrance door is detected, the air discharger is tilted to a preset initial position to stop the discharging of air. Accordingly, during the opening of the entrance door, the introduction of external air into the space of the entrance hall may be minimized.

Abstract: A hygiene management device for an entrance hall is designed to emit far-UV light from upper and lower sides toward a person by reflecting the far-UV light emitted from the upper side to the person's lower body by a reflector located at the lower side, and reflecting the far-UV light emitted from the lower side to the person's upper body by a reflector located at the upper side. Accordingly, a sterilization effect on the person is improved.

Abstract: A hygiene management device for an entrance hall and the control method of the same are proposed. The hygiene management device may be installed in an entrance space, and when a person is detected at a preset position, distance between an air discharger and the person may be detected. When the detected distance is within a reference distance, air may be discharged. In addition, an air discharge condition suitable for a person may be preset, and when the person enters the entrance hall, the person's face may be detected, and air may be discharged to the person according to the air discharge condition preset for the person.

Abstract: A hygiene management device for an entrance hall includes a footrest located on the bottom of an entrance space to introduce air to the footrest and may transmit the air to an air management module. In the air management module, the air may be purified and the temperature thereof may be preset. The air may be flown through a duct by a fan assembly. The air flowing through the duct may pass through a second duct located at the ceiling of the entrance space and be transmitted to an air discharger. The air discharger may adjust directions to which discharge holes are directed such that air can be discharged to a person standing on the footrest in various directions, and the discharged air may be introduced into the footrest.
