Abstract

Official abstract text for this publication.

An air cleaner according to the present disclosure includes: a first body having an inlet and an outlet; a filter disposed inside the first body and facing the inlet; a blower fan disposed between the inlet and the outlet inside the first body; a blower motor disposed inside the first body and configured to rotate the blower fan; and a second body coupled to an upper side of the first body and extending along a lateral direction, wherein the second body includes an indicator configured to display an operation state, wherein the indicator has a lamp configured to emit light and a lamp housing in which the lamp is disposed, and wherein the lamp housing has a groove to allow light emitted by the lamp to pass through.

First claim

Opening claim text (preview).

What is claimed is: 1 . An air cleaner comprising: a first body having an inlet, an outlet, and a filter positioned between the inlet and the outlet; and a second body coupled to an upper side of the first body and extending laterally, wherein the second body includes an indicator light configured to display an indication of an operation state of the air cleaner, wherein the indicator light includes a plurality of lamps and a lamp housing in which the plurality of lamps are provided, and wherein the lamp housing includes a partition wall positioned between two of the plurality of lamps. 2 . The air cleaner of claim 1 , wherein the lamp housing has a groove through which light emitted by the lamp passes out of the lamp housing. 3 . The air cleaner of claim 2 , wherein the second body includes, on an upper surface thereof, a slot at which the lamp housing is provided, and wherein the lamp housing is provided at the slot so as to be exposed through the upper surface of the second body. 4 . The air cleaner of claim 3 , wherein the lamp housing includes an upper wall that covers the lamp and is provided at the slot to define a section of the upper surface of the second body, and wherein the groove is formed at the upper wall of the housing. 5 . The air cleaner of claim 4 , wherein the groove is formed on a lower surface of the upper wall of the housing so as not to be exposed outside of the second body at the upper surface of the second body. 6 . The air cleaner of claim 4 , wherein the groove is located above and vertically aligned with the lamp. 7 . The air cleaner of claim 4 , wherein the indicator light includes a substrate to which the lamp is connected, wherein the lamp housing has an opening that is open in a direction facing the substrate, and the lamp is positioned in the opening of the lamp housing, wherein the substrate covers the opening of the lamp housing, and wherein the lamp is provided between the upper wall of the lamp housing and the substrate. 8 . The air cleaner of claim 3 , further comprising a button module, wherein the lamp housing is provided at the slot to define a section of the upper surface of the second body, and wherein the button module is provided below the indicator light to define a section of a lower surface of the second body. 9 . The air cleaner of claim 8 , wherein a thickness of the second body decreases toward an edge thereof, and wherein the indicator light and the button module are provided to be in contact with each other inside the second body. 10 . The air cleaner of claim 3 , wherein the second body includes: a lower cover extending laterally; and a top plate provided over the lower cover and defining the upper surface of the second body, and wherein the slot is formed on the top plate. 11 . The air cleaner of claim 10 , wherein the second body includes an intermediate plate provided between the lower cover and the top plate, and wherein the lamp housing protrudes upward from the intermediate plate. 12 . The air cleaner of claim 11 , further comprising a charging pad protruding from the intermediate plate, wherein the top plate includes a pad hole at which the charging pad is positioned. 13 . The air cleaner of claim 11 , wherein the intermediate plate includes a slot water collection channel recessed downward along at least a portion of a circumference of the lamp housing. 14 . The air cleaner of claim 13 , wherein the intermediate plate includes: a main water collection channel spaced apart from a central region of the intermediate plate and recessed downward to extend in a circumferential direction; and a connecting water collection channel connecting the main water collection channel and the slot water collection channel. 15 . The air cleaner of claim 12 , wherein the charging pad and the lamp housing have different shapes when viewed from above. 16 . The air cleaner of claim 10 , wherein the top plate includes a lateral cover wall to cover a lateral surface of the lower cover, and wherein the lower cover includes a lateral wall extending from a lateral end of the lower cover to be in contact with an inside of the lateral cover wall. 17 . The air cleaner of claim 16 , further comprising an intermediate plate from which the lamp housing protrudes, the intermediate plate being positioned between the top plate and the lower cover, wherein the intermediate plate includes a hooking rib extending from a lateral end of the upper plate to be in contact with an inside of the lateral wall of the lower cover, so as couple the intermediate plate to the lower cover. 18 . The air cleaner of claim 8 , wherein the indicator light includes a substrate having a first surface facing the grove and on which the lamp is positioned, wherein the button module includes a button, and wherein the air cleaner further comprises a button sensor that is configured to detect when the button is pressed by a user and is connected to a second surface of the substrate.
