Description

Humidifier and humidifying air purifier including the same

[0001] The present disclosure relates to a humidifier and a humidifying air purifier including the same.

[0002] Generally, a humidifier refers to a device that maintains the humidity of an indoor space at an appropriate level. A humidifier can vaporize water contained in a tank and discharge it into the indoor space.

[0003] Humidifiers can be broadly classified into evaporative, ultrasonic, and heating types based on the humidification method of vaporizing water. Among these, in the case of the heating humidification method, steam can be generated by a steam generating unit heating and vaporizing water contained in a water reservoir.

[0004] An air purifier is a device used to remove pollutants from the air. It can remove bacteria, viruses, mold, fine dust, and odor-causing chemicals present in the inhaled air.

[0005] An air purifier may be equipped with a filter to purify contaminated indoor air. Air drawn into the air purifier passes through the filter, where pollutants are removed to purify it into clean air, and the purified air can be discharged to the outside of the air purifier.

[0006] In this way, humidifiers and air purifiers are used to manage indoor air. Recently, humidifying air purifiers, which combine both humidification and air purification into a single device, are being used.

[0007] The above information is provided merely as background information to aid in understanding the present disclosure. No judgment or claim is made regarding whether the above information can be applied as prior art with respect to the present disclosure.

[0008] One aspect of the present disclosure is intended to partially resolve the aforementioned problems and / or disadvantages and to provide the advantages described below. Accordingly, a humidifier with an improved structure and a humidifying air purifier including the same are provided.

[0057] FIG. 3 is an exploded view of a humidifier according to one embodiment of the present disclosure.

[0058] Referring to FIG. 3, a humidifier (2) according to one embodiment of the present disclosure may include a cap (300), a water tank (200), and a housing (100).

[0059] A cap (300) may be provided to open and close a water tank (200) to be described later. The cap (300) may be detachably provided by being coupled to the upper part of the water tank (200). The cap (300) may include a button (310) and a lever (320, see FIG. 4 and 5). To separate the cap (300) from the water tank (200), the button (310) may need to be pressed.

[0060] The cap (300) may include a handle (330). The user can easily operate the cap (300) using the handle (330). The user can easily press the button (310) using the handle (330) and then rotate the cap (300).

[0061] The cap (300) may include a cap body (340) and a cap rib (350). The cap rib (350) may be formed to protrude downward from the bottom of the cap body (340). As will be described later, the cap (300) may be separated from the water tank (200) after being rotated by a predetermined angle. The cap rib (350) may prevent the cap body (340) from rotating.

[0062] The tank (200) may be cylindrical in shape.

[0063] The water tank (200) may be detachable from the cap (300). The water tank (200) may include a lever groove (220). As will be described later, when the button (310) is pressed, the lever (320) may be removed from the lever groove (220). There may be multiple lever grooves (220). The cap (300) may be coupled to the water tank (200) at a position where a part of the lever (320) can be received in the lever groove (220).

[0064] The tank (200) may include ribs (210). As will be described later, the ribs (210) may be accommodated in a rib guide (360, see FIG. 6). The number of ribs (210) may be multiple.

[0065] The tank (200) may include a protrusion (230). The protrusion (230) may protrude from the outer surface of the tank (200). The housing (100) may include a seating portion (120). The protrusion (230) may be seated in the seating portion (120) by means of an opening (123). The protrusion (230) and the seating portion (120) are formed to correspond to each other so that when the tank (200) is received in the housing (100), rotation of the tank (200) can be prevented.

[0066] FIG. 4 is an enlarged cross-sectional view of a portion of a humidifier according to one embodiment of the present disclosure. FIG. 5 is an enlarged cross-sectional view of a portion of a humidifier according to one embodiment of the present disclosure.

[0067] Referring to FIGS. 4 and 5, a humidifier (2) according to one embodiment of the present disclosure may include a lever (320). The lever (320) may include a lever shaft (321), a first part (322), and a second part (323). The first part (322) may be positioned to be in contact with a button (310).

[0068] The lever (320) may be rotatably provided around the lever shaft (321). When no external force is applied to the lever (320), a portion of the second part (323) may be received in the lever groove (220). When a portion of the lever (320) is received in the lever groove (220), the cap (300) may be prevented from rotating relative to the water tank (200).

[0069] When the button (310) is pressed downward, the lower part of the button (310) can press the first part (322) downward. When the first part (322) is pressed downward, the lever (320) rotates around the lever shaft (321) so that the second part (323) can be removed from the lever groove (220).

[0070] The lever (320) may include a spring. When the external force acting on the lever (320) is removed, the lever (320) can return to a state in which a part of the second part (323) is received in the lever groove (220) through the elastic force of the spring.

[0071] FIG. 6 is an enlarged cross-sectional view of a portion of a humidifier according to one embodiment of the present disclosure. FIG. 7 is an exploded view of a humidifier according to one embodiment of the present disclosure. FIG. 8 is an enlarged view of a portion of a humidifier according to one embodiment of the present disclosure.

[0072] Referring to FIGS. 6 through 8, a humidifier (2) according to one embodiment of the present disclosure may include a rib guide (360). A cap (300) may include a rib guide (360). A rib (210) may be received in the rib guide (360).

[0073] When the cap (300) is rotated, the rib (210) may move in a first direction (a) or a second direction (b). When the cap (300) is rotated so that the rib (210) moves in the first direction (a), the cap (300) may be separated from the water tank (200). When the cap (300) is rotated so that the rib (210) moves in the second direction (b), the cap (300) may be separated from the water tank (200).

[0074] The number of ribs (210) can be provided in multiple numbers. The number of rib guides (360) can be provided in multiple numbers. The number of rib guides (360) can be formed to correspond to the number of ribs (210).

[0075] When the cap (300) is combined with the water tank (200) and the water tank (200) is received in the housing (100), the cap rib (350) can be received in the seating portion (120). The cap rib (350) can prevent the cap (300) from rotating relative to the water tank (200). Since the cap (300) can be separated from the water tank (200) after rotating relative to the water tank (200), the separation of the cap (300) can be prevented.

[0076] The seating portion (120) may include a base (121) that supports the protrusion (230). The seating portion (120) may include side walls (122) that are bent at both ends of the base (121).

A locking part (240) may be formed on the outer surface of the water tank (200). The locking member (500) may be received in the locking part (240) to prevent separation from the housing (100) of the water tank (200). The locking part (240) may be a groove, hole, or rib formed on the outer surface of the water tank (200). The locking part (240) may be formed along the outer perimeter of the water tank (200).
