[0125] The inner shell body (181) includes a cylindrical perimeter wall (181a) and a lower wall (181b) that protrudes inward from the lower end of the perimeter wall (181a). The lower wall (181b) has a shape that slopes downward as it moves away from the perimeter wall (181a).

[0126] The light guide rib (182) extends from the lower end of the perimeter wall (181a) to the lower side of the lower wall (181b).

[0127] The bottom of the light guide rib (182) is positioned higher than the bottom of the lower wall (181b).

[0128] When the inner shell (180) is placed on the upper side of the middle tray (200), the lower rib (190) may be placed at a certain distance upward from the upper surface of the middle tray (200).

[0129] A shell penetration hole (184) is formed in the center of the lower wall (181b) of the inner shell (180).

[0130] The upper portion (180a) of the inner shell (180) has an inwardly inclined shape. The upper portion (180a) of the inner shell (180) forms an inwardly inclined surface toward the humidifying air flowing and discharged from the first discharge channel (32).

[0131] The upper surface (180a1) of the inner shell (180) is formed to be inclined inward. The angle of inclination (θ) formed by the upper surface (180a1) of the inner shell (180) with a horizontal imaginary line is an angle of 40 to 60 degrees. Accordingly, light can be emitted through humidified air flowing upward through the first discharge channel (32) into the inner shell (180).

[0132] Therefore, light can be generated by the humidified air flowing upward from the discharge port.

[0133] Referring to Fig. 7, the configuration and connection relationship of the middle tray will be explained.

[0134] The middle tray (200) includes a tray body (201) and a tray base (215) positioned below the tray body (201). A space is formed between the tray base (215) and the tray body (201) in which an internal configuration is placed.

[0135] The tray body (201) includes a tray plate (202) forming an upper surface and a tray perimeter wall (203) forming a perimeter surface.

[0136] A weight sensor (226, 227) is placed on the tray base (215). A pressing body (225) is placed on the upper side of the weight sensor (226, 227). A sensor cover (210) is placed on the upper side of the pressing body (225).

[0137] A sensor groove (208) is formed in the tray plate (202). A sensor groove flange (208a) is disposed on the tray plate (202) and protrudes upward from the periphery of the sensor groove (208). A cover rib (209) is disposed on the tray plate (202) and protrudes inward from the area where the sensor groove (208) is formed. The cover rib (209) protrudes inward from the lower end of the sensor groove flange (208a).

[0138] The sensor cover (210) can be mounted on the cover rib (209). The sensor cover (210) can be formed in a structure where its outer edge wraps around the cover rib (209). The sensor cover (210) can be formed in a structure where its outer edge wraps around the top and bottom of the cover rib (209).

[0139] The sensor cover (210) can be positioned to be in contact with the pressing body (225). The sensor cover (210) can prevent water from entering the middle tray (200) through the sensor groove (208).

[0140] An exhaust hole (215b) is formed below the second hole (206) in the tray base. An exhaust hole rib (216) is disposed in the tray base (215) and protrudes inward from the area where the exhaust hole (215b) is formed. The exhaust hole rib (216) is disposed below the tray plate (202).

[0141] A tray sealer (217) is placed in the exhaust hole (215b) formed in the tray base (215) to prevent water from flowing into the internal space of the middle tray (200).

[0142] A lamp device (240) in which a lamp (242) is placed is arranged around the perimeter of the middle tray (200). The lamp device (240) includes a lamp (242) and a lamp housing (246) that forms a space in which the lamp (242) is placed.

[0143] A printed circuit board (244) is placed in the lamp device (240) to control the operation of the lamp (242).

[0144] A lamp (242) is disposed on the upper surface of a printed circuit board (244). The lamp (242) includes a first surface (242a) from which light is emitted. The first surface (242a) may be a surface facing upward. A lamp housing hole (247) is formed above the first surface (242a) in which a light guide rib (182) is disposed.

[0145] A lamp (229a) can be placed below the lamp housing (229).

[0146] In the lamp housing (229), a lamp housing hole (247) into which a light guide rib (182) is inserted is formed.

[0147] The printed circuit board (244) positions the lamp (242) upward from the bottom surface of the lamp housing (246). Thus, the gap between the light guide rib (182) and the lamp (242) can be reduced. Additionally, the length of the light guide rib (182) can be reduced.

[0148] Referring to Fig. 8, the arrangement relationship of the lower ribs is explained with the inner shell placed on top of the middle tray.

[0149] The lamp device (240) includes a lamp (242), a lamp housing (246) forming a space in which the lamp (242) is placed, and a printed circuit board (244) in which the lamp (242) is placed and which operates the lamp (242).

[0154] The lamp (242) includes a first surface (242a) that emits light. The first surface (242a) is positioned to face the bottom surface of the light guide rib (182). When the inner shell (180) is placed in the middle tray (200), the bottom surface of the light guide rib (182) is positioned to face the first surface (242a) of the lamp (242).

[0155] The thickness (182t) of the light guide rib (182) is formed to become thicker from the bottom to the top. The spacing (L1) between the light guide rib (182) and the lamp (242) is formed to be narrower than the thickness (182t) of the light guide rib (182).

[0156] The light guide rib (182) is positioned parallel to the perimeter wall (181a) of the inner shell (180). Thus, light emitted from the lamp (242) can be transmitted to the perimeter wall of the inner shell (180) through the light guide rib (182).

[0157] The lower wall (181b) of the inner shell (180) is positioned obliquely to the perimeter wall (181a) and the light guide rib (182) of the inner shell (180).

[0158] Referring to FIG. 9, the arrangement relationship of the lower ribs is explained with the inner shell according to another embodiment placed on top of the middle tray.

[0159] The lamp device (240) includes a lamp (242), a lamp housing (246) forming a space in which the lamp (242) is placed, and a printed circuit board (244) in which the lamp (242) is placed and which operates the lamp (242).

[0160] In the lamp housing (246), a lamp housing hole (247) is formed that is open above the lamp (242).

[0161] The lamp housing (246) may be the tray perimeter wall (203) described in FIG. 7.

[0162] The lamp housing (246) is positioned on the outside based on the lamp housing hole (247).

[0163] When the inner shell (180) is placed in the middle tray (200), the light guide rib (182) of the inner shell (180) is placed on one side of the lamp housing (246). When the inner shell (180) is placed in the middle tray (200), the light guide rib (182) of the inner shell (180) is placed on the lamp (242).

[0164] When the inner shell (180) is placed in the middle tray (200), the bottom surface of the light guide rib (182) is positioned to face the first surface (242a) of the lamp (242).

[0165] The light guide rib (182) is positioned parallel to the perimeter wall (181a) of the inner shell (180). Thus, light emitted from the lamp (242) can be transmitted to the perimeter wall of the inner shell (180) through the light guide rib (182).

[0166] Referring to FIG. 10, the arrangement relationship of the lower ribs is explained with the inner shell according to another embodiment placed on top of the middle tray.

[0167] The lamp device (240) includes a lamp (242), a lamp housing (246) forming a space in which the lamp (242) is placed, and a printed circuit board (244) in which the lamp (242) is placed and which operates the lamp (242).

[0168] In the lamp housing (246), a lamp housing groove (248) is formed that is open above the lamp (242).

[0169] The lamp housing (246) may include the tray perimeter wall (203) described in FIG. 7.

[0170] The lamp housing (246) includes a first lamp housing (246a) positioned on the inner side relative to the lamp housing groove (248) and a second lamp housing (246b) positioned on the outer side relative to the lamp housing groove (248).

[0171] The lamp housing (246) includes a rib mounting portion (249) that forms a lamp housing groove (248) into which a light guide rib (182) is inserted.

[0172] The rib mounting portion (249) is formed in a shape and size corresponding to the optical guide rib (182).

[0173] When the inner shell (180) is placed in the middle tray (200), the light guide rib (182) of the inner shell (180) is inserted into the lamp housing groove (248). When the inner shell (180) is placed in the middle tray (200), the light guide rib (182) of the inner shell (180) is placed on the lamp (242).

[0174] When the inner shell (180) is placed in the middle tray (200), a rib mounting portion (249) is placed between the lamp (242) and the light guide rib (182).

[0175] The thickness (249t) of the rib mounting portion (249) is formed to be smaller than the thickness (182t) of the light guide rib (182). The thickness (249t) of the rib mounting portion (249) is formed to be smaller than the thickness (246t) of the lamp housing (246).

[0176] The thickness (249t) of the rib mounting portion (249) is formed to be equal to or smaller than the spacing (L2) between the rib mounting portion (249) and the lamp (242).

[0177] The lamp (242) includes a first surface (242a) that emits light. The first surface (242a) is positioned to face the rib mounting portion (249). When the inner shell (180) is placed in the middle tray (200), the bottom surface of the light guide rib (182) is positioned to face the first surface (242a) of the lamp (242).

[0178] The thickness (182t) of the light guide rib (182) is formed to become thicker from the bottom to the top. The spacing (L2) between the rib mounting portion (249) and the lamp (242) is formed to be narrower than the thickness (182t) of the light guide rib (182).

[0179] The light emitted from the lamp (242) is transmitted through the rib mounting portion (249) to the light guide rib (182) and the perimeter wall of the inner shell (180). The light guide rib (182) is positioned parallel to the perimeter wall (181a) of the inner shell (180). Thus, the light emitted from the lamp (242) can be transmitted to the perimeter wall of the inner shell (180) through the light guide rib (182).

[0180] The lower wall (181b) of the inner shell (180) is positioned obliquely to the perimeter wall (181a) and the light guide rib (182) of the inner shell (180).

[0184] The inner shell (180) is placed on top of the middle tray (200). The inner grill (232) is placed on top of the middle tray (200). The outer shell (22) is placed on top of the inner grill (232).

[0185] A water tank cover (14) and a discharge grille (12) are placed on top of the inner shell (180) and the outer shell (22).

[0186] The inner shell (180) is formed of a transparent material. The outer shell (22) may be partially formed of a transparent material.

[0187] The lower outer shell (22b) can be formed of a transparent material. Therefore, the inside of the inner shell (180) can be seen through the lower outer shell (22b).

[0188] As humidified air flows through the first discharge channel (32), the interior may be opaque. Therefore, it is emitted from the lamp device (240) and emitted via the inner shell (180). Thus, from the outside, the light emitted from the inner shell (180) can be visually confirmed. Additionally, a part of the outer shell (22) is formed transparently so that the light emitted from the inner shell (180) can be confirmed from the outside.

[0189] Although preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present disclosure.
