    Abstract: The present invention relates to a gas sensor employing a non-dispersive infrared (NDIR) scheme. The gas sensor may comprise: a light source portion for emitting light; a light cavity portion for multi-reflecting the emitted light; a light detecting portion for detecting the multi-reflected light; a first light coupling portion for reflecting and concentrating the light emitted by the light source portion toward the light cavity portion; and a second light coupling portion for reflecting and concentrating the light reflected by the light cavity portion toward the light detecting portion. The first light coupling portion may comprise a light emitting surface that faces a side surface of the light cavity portion and has a via hole through which light passes, and a reflecting surface extending from the light emitting surface so as to surround the upper portion and the side portion of the light source portion such that light emitted by the light source portion is reflected toward the via hole of the light emitting surface. The second light coupling portion may comprise a light incident surface that faces a side surface of the light cavity portion and has a via hole through which light incident from the light cavity portion passes, and a reflecting surface extending from the light incident surface so as to surround the upper portion and the side portion of the light detecting portion such that light incident from the light cavity portion is reflected toward the light detecting portion.

    Abstract: Disclosed is a cleaner, including a main body having an operating part configured to receive a command and a main battery configured to supply power; and a cleaning module connected to the main body and configured to generate steam to clean a cleaning region, and the cleaning module may include: a cleaning module housing connected to the main body, forming an external appearance, and forming a space on an inside thereof; a heater disposed on an inside of the cleaning module housing and configured to generate steam from water; a water container disposed above the heater and configured to supply the water to the heater; and a heater disposition part recessed upward from a lower surface of the water container and allowing at least a part of the heater to be inserted thereinto. The present disclosure relates to a cleaner capable of preventing burns to a user even if the user comes into contact with the cleaning module since heat dissipated from the heater is shielded by the water container, and lowering a height of the cleaning module thanks to a special structure of the water container.

    Abstract: A robot cleaner includes a main body which forms an external shape; two or more spin mops which rotate in a clockwise or counterclockwise direction when viewed from above and mop a floor with a damp cloth, and move the main body; and a cleaning module which is positioned in front of the spin mops and collects foreign substance existing on a cleaning target surface, wherein the cleaning module includes: a housing which is coupled to the main body and opened at a lower side; a dust container which forms a space for accommodating foreign substance and is positioned to be detachable in a lower side direction of the housing; and an agitator which is positioned inside the housing, and sends foreign substance existing on the cleaning target surface to the dust container by a rotation operation.

    Abstract: A cleaner includes a body including an insertion slot facing a floor and an installation space inside the body. The cleaner includes a dust housing detachably connected to the body. The dust housing includes a collection opening surface and a storage space that stores foreign substances collected through the collection opening surface. The cleaner has an agitator rotatably connected to the dust housing and exposed through the collection opening surface. The cleaner also includes a driving apparatus that rotates a driving coupler, which drives a driven coupler coupled to the agitator. The cleaner includes a lever located on either the driving coupler or the driven coupler. The lever selectively attaches or separates the driving coupler and the driven coupler. Manipulating the lever separates the driving coupler and the driven coupler and allows the sweep module including the agitator to be removed through the insertion slot in the body.

    Abstract: The present disclosure relates to a cleaner including a cleaning module which cleans a cleaning area by generating steam. The cleaning module includes: a cleaning module housing which is connected to the main body, forms an appearance, and forms a space therein; a heater which is disposed within the cleaning module housing and generates steam from water; an air inlet which is formed on one side of the cleaning module housing and into which external air is introduced; and an air outlet which is formed on the cleaning module housing, is disposed above the air inlet, and through which the air in an internal space of the cleaning module is discharged to the outside. As a result, electronic equipment disposed around the heater can be prevented from being damaged by the heat emitted from the heater.
