Abstract: The present invention relates to an air cleaner, including a body forming an exterior; a suction portion formed on the body to suck air; a discharge portion formed on the body and discharging the air sucked through the suction portion; and a fan module provided in the body to form a flow of air flowing from the suction portion to the discharge portion, wherein the fan module includes: a driving portion forming a rotation shaft and generating power; a fan receiving the power from the driving portion and rotating about the rotation shaft; and a shroud accommodating the fan and provided between the suction portion and the discharge portion to guide the air sucked through the suction portion to the discharge portion, and the shroud includes a guide portion guiding foreign substances introduced through the discharge portion in a direction opposite to the flow of air.

Abstract: Various embodiments of the present invention disclosed herein relate to an air cleaner, and may suck outside air and purify and sterilize the outside air, and may perform sterilization of a filter. An embodiment of the invention disclosed herein discloses an air cleaner including a body forming an appearance; a suction unit formed on the body and introduced with outside air; a discharge unit formed on the body and discharging the air introduced through the suction unit; a fan module provided inside the body and forming a flow of air introduced into the suction unit and discharged to the discharge unit; a filter unit provided inside the body to filter the air introduced into the suction unit; and a light source unit provided inside the body and irradiating light toward an inner side surface of the filter unit.

Abstract: A floating type humidifier with an increased humidification amount according to an exemplary embodiment of the present invention includes: a floating body which floats on water accommodated in a water tub and has a hollow portion vertically and penetratively formed at a central portion of the floating body; an ultrasonic generator which is installed in the hollow portion and configured to atomize water, which is introduced at a lower portion, to create humidification particles by using ultrasonic vibration; a humidification particle guide unit which is installed on an upper portion of the floating body and guides the humidification particles so that the humidification particles move upward along a guide hole in the humidification particle guide unit; and an air pressurizing portion which is provided in the humidification particle guide unit and pressurizes air so that the humidification particles are moved upward by the pressurized air.

Abstract: Detachable Internet of Things (IoT) modules can be coupled to products such as home appliances to create an IoT environment or ecosystem. The detachable IoT module includes a communication module insertable into a groove formed about an exterior surface of a home appliance and electrically connected with a controller in the home appliance, and a sensor module coupled to the communication module and electrically connected with the controller through the communication module, the sensor module capable of measuring an air state near the home appliance, where the sensor module and the home appliance are in wireless communication with an external terminal through the communication module.

Abstract: An air cleaner according to an exemplary embodiment of the present invention includes a water tank in which water is contained, a rotating shaft which is mounted in the water tank and rotates, and a rotating body which is coupled to the rotating shaft to rotate in a longitudinal direction of the rotating shaft as a rotational axis and formed with a plurality of rotating blades capable of collecting air, in which the rotating shaft is obliquely mounted to form a predetermined angle with a water surface formed by the water contained in the water tank.

Abstract: An ultrasonic humidifier according to an embodiment of the present invention includes: a water bottle accommodating water capable of generating humidification; a water bottle lid covering an upper opening surface of the water bottle and including a humidification outlet for discharging the humidification; and an ultrasonic humidification generating module which floats submersibly in the water accommodated in the water bottle and generates humidifying particles by using ultrasonic waves.
