Description

humidifier

[0001] The present disclosure relates to a humidifier, and more specifically, to a humidifier in which the flow of discharged humidified air can be visually observed.

[0002] A humidifier is a device that uses water to generate humidified air and regulates humidity by releasing the humidified air.

[0003] Recently, home appliances, including humidifiers, can also be utilized as interior design elements in indoor spaces. Therefore, appliances such as humidifiers can provide both visual aesthetic effects and functionality simultaneously through structures that reveal the flow of humidifying air inside.

[0004] Registered Patent KR No. 10-2500340 discloses a humidifier comprising a light-transmitting plate (or 'transparent window') on the outer surface. Accordingly, a structure is provided that allows the humidified air rising inside to be visually observed from the outside.

[0005] However, since these transparent windows are always exposed to the outside, there is a risk of damage. In addition, when they are damaged or subjected to external impact, problems may arise such as the light-transmitting panel becoming opaque or a gap forming through the outside and inside.

[0006] Noise from the heater or vibrator operating to generate humidified air may be emitted externally.

[0007] For home appliances such as humidifiers, a structure in which some components are movable can be developed for reasons of product compactness or design.

[0008] KR 10-1336898 B1 discloses a humidifier in which some components move.

[0009] However, if the moving structure alters the path through which humidified air flows, a problem may arise where water accumulates in areas other than the region where the humidified air flows.

[0010] The present disclosure aims to solve the aforementioned problems and other problems.

[0011] Another objective is to provide a humidifier that visualizes the internal airflow by exposing a transparent window to the outside when the humidifier is operating. Additionally, to provide a humidifier that protects the transparent window by concealing it when the humidifier is not operating.

[0012] The invention provides a humidifier in which the flow of humidified air can be observed by arranging multiple transparent windows in the same line of sight.

[0013] Another objective is to provide a humidifier that moves an outer shell positioned externally in an up-and-down direction through a drive mechanism positioned internally.

[0014] In addition, it provides a humidifier that stably moves the moving cylinder.

[0015] In addition, the externally moving outer shell provides a humidifier capable of stable movement in relation to the transparent window.

[0016] Another objective is to provide a humidifier that expands the flow path of filtered air flowing through a blower fan. By expanding the flow path of the air purification channel, the humidifier provides an increase in the straightness of the air flowing upward.

[0017] Another objective is to provide a humidifier that reduces noise emitted from the humidifier to the outside.

[0018] Another objective is to provide a humidifier in which rapid dispersion and diffusion occur when humidified air is discharged through an outlet.

[0019] Another objective is that when humidified air flows into a space other than the air passage through which it is discharged, water generated upon contact with the humidified air may accumulate or form outside the air passage. The present disclosure provides a humidifier that solves this problem.

[0020] In addition, since such stagnant water can cause internal contamination, it is necessary to remove the collected water. The present disclosure provides a humidifier that solves this problem.

[0021] In addition, a structure or notification may be required to facilitate the smooth removal of such stagnant water. The present disclosure provides a humidifier that solves these problems.

[0022] In addition to flowing filtered air upward, the blower fan can assist in the flow of humidified air. However, if air is not supplied smoothly to the humidification tank, a problem may arise in which the range of humidified air flow is limited.

[0096] Specific details of other embodiments are included in the detailed description and drawings.

[0097] According to the humidifier of the present disclosure, there is one or more of the following effects.

[0098] First, the outer shell is positioned around the outer perimeter of the outer transparent window or has a structure that moves upward. This offers the advantage of allowing the flow of humidified air inside to be visually checked from the outside when the humidifier is operating.

[0099] In addition, when the humidifier is not in operation, an outer shell is positioned around the outer perimeter of the outer transparent window, which has the advantage of protecting the window. In other words, it prevents the transparent window from being damaged or broken by external impacts.

[0100] Second, an inner transparent window is also installed in the moving cylinder positioned inside. Additionally, when the outer transparent window is exposed, the inner transparent window is positioned in the same line of sight, allowing the flow of humidified air inside to be observed.

[0101] Third, the moving cylinder can be moved stably through the structure of the motor, gear, and rack gear positioned inside the inner housing. In addition, the outer transparent window in contact with the outer shell can maintain stable movement while minimizing friction through an outwardly protruding flange and a tip structure.

[0102] Fourth, the moving cylinder forms a flow path between the case and the air, and when the moving cylinder moves upward, the air flow path is expanded, thereby improving the straightness of the rising air.

[0103] Fifth, humidified air flowing through the first discharge channel is discharged to the outlet via the expansion channel. The expansion channel acts as a bumper for the air flowing through the first discharge channel, thereby reducing noise from escaping to the outside.

[0104] Therefore, it has the advantage of minimizing the transmission of noise generated by the humidifier to the outside.

[0105] Sixth, the air flowing through the first discharge channel forms turbulence through the diffusion channel, and its velocity is reduced before being discharged to the outside. This allows the air discharged to the outlet to be well dispersed.

[0106] However, since air from the blower fan flows upward through the additional airflow, it can facilitate the discharge of humidified air to the outlet. Through this structure, the humidified air discharged to the outlet is dispersed and diffused, allowing it to rapidly circulate over a wide area of ​​the indoor space.

[0107] Seventh, water generated inside the moving cylinder moving within the humidifier can be temporarily collected at the upper wall of the inner housing. In other words, water generated during the process of humidifying air generation and flow can be collected in a designated space.

[0108] It can prevent water from flowing into other spaces. It can control the water generated during the process of humidifying air generation and flow.

[0109] Eighth, a drain hole, a drain hose, and a drain valve are provided in the inner housing to discharge water above a certain level. Additionally, a water level sensor is placed on one side to notify the user or prevent water from overflowing from the upper wall of the inner housing.

[0110] Ninth, by directing a portion of the air flowing through the blower fan into the inner side of the moving cylinder, water generated on the inner circumference of the moving cylinder can be dried. Additionally, there is the advantage of being able to actively promote the flow of humidified air.

[0111] The effects of the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims.

[0178] The fan sterilization device can sterilize the inside of the blower fan (62) or filter (50) described below.

[0179] An orifice (56) is formed in the upper plate (54). The orifice (56) may be formed at the center of the upper plate (54). The orifice (56) can allow air introduced into the filter (50) to flow to the blower fan (62).

[0180] The inner end of the upper plate (54) has a shape that is bent upward, so that air flowing upward in the internal space of the filter (50) can be guided to the blower fan (62).

[0181] The supporter can connect the lower plate (52) and the upper plate (54). The supporter can be spaced apart in the circumferential direction.

[0182] The blower device (60) includes a blower fan (62) that forms air flow inside the case (10) and a fan motor (64) that rotates the blower fan (62).

[0183] The blower fan (62) may form a fan intake port on one side facing the orifice (56) and a fan discharge port on the opposite side of the fan intake port. The blower fan (62) may use a centrifugal fan in which the fan discharge port faces the centrifugal direction on the opposite side of the fan intake port.

[0184] The blower fan (62) may include a hub connected to a fan motor (64), a shroud spaced apart from the hub and forming a fan intake, and a blade extending radially to connect the hub and the shroud.

[0185] The blower fan (62) can send air from the lower side to the upper side by operation. The blower fan (62) can draw air toward the orifice (56) and discharge air toward the blower housing (68) where the diffuser (68a) is placed.

[0186] The fan motor (64) can be positioned above the blower fan (62).

[0187] The blower device includes a motor cover (66) that covers the outside of a fan motor (64), and a blower housing (68) that is spaced radially outward from the motor cover (66) and guides the air flowing by the blower fan (62) upward.

[0188] Between the motor cover (66) and the blower housing (68), a blower passage (35) can be formed through which air flowing by the blower fan (62) flows upward.

[0189] The airflow passage (35) may lead to a second discharge passage (34) formed between the outer shell (22) and the moving cylinder (94). The second discharge passage (34) is located above the airflow passage (35). The second discharge passage (34) may be a passage continuous with the airflow passage (35).

[0190] Most of the air flowing through the blower channel (35) flows into the second discharge channel (34). A portion of the air flowing through the blower channel (35) flows into the additional channel (33).

[0191] A lower outer shell (22b) may be placed on the outside of the blower housing (68).

[0192] A blower fan (62) is positioned between a motor cover (66) and a blower housing (68). The blower housing (68) includes a diffuser (68a) that reduces the rotational component of the air flowing upward by the blower fan (62). Multiple diffusers (68a) may be arranged spaced apart in the circumferential direction.

[0193] An inner housing (70) is disposed on top of the motor cover (66). The inner housing (70) can form a space in which a circuit board (76) is disposed. A moving motor (90) that moves the moving cylinder (94) described below can be disposed inside the inner housing (70).

[0194] A rotating motor gear (91) connected to a moving motor (90) can be placed inside the inner housing (70).

[0195] A ventilation passage (35) is formed between the inner housing (70) and the lower outer shell (22b).

[0196] A humidification module is placed on top of the inner housing (70). On top of the inner housing (70), a humidification module housing (410) is placed to form a space in which a humidification water tank is placed inside.

[0197] A moving cylinder (94) is positioned above the inner housing (70) to be movable in the vertical direction. A humidification module housing (410) is positioned inside the moving cylinder (94).

[0198] The moving cylinder (94) includes a rack gear (92) that meshes with the motor gear (91) and moves in the up and down direction. The rack gear (92) is positioned to penetrate the upper surface of the inner housing (70).

[0199] The moving cylinder (94) is positioned inside the outer shell (22). Between the moving cylinder (94) and the outer shell (22), a first discharge passage (34) is formed, extending from a blower passage (35) through which air passing through the filter (50) flows.

[0200] The moving cylinder (94) is arranged radially spaced around the outer circumference of the humidification module. The moving cylinder (94) is arranged radially spaced around the outer circumference of the inner shell (180).

[0201] The moving cylinder (94) includes a lower moving cylinder (94a) positioned around the outer perimeter of the humidification module. The lower moving cylinder (94a) is positioned inside the lower outer shell (22b).

[0202] The moving cylinder (94) includes an upper moving cylinder (94b) positioned around the outer perimeter of the inner shell (180). The upper moving cylinder (94b) is positioned inside the upper outer shell (22a).

[0203] The moving cylinder (94) includes an inner transparent window (94c) positioned between the lower moving cylinder (94a) and the upper moving cylinder (94b).

[0204] When the outer transparent window (23) is positioned to be exposed to the outside, the inner transparent window (94c) is positioned on the inner side of the outer transparent window (23). The length of the inner transparent window (94c) formed in the vertical direction may be longer than the length of the outer transparent window (23) formed in the vertical direction.

[0205] The moving cylinder (94) includes a bridge (98) that extends radially outward to connect the moving cylinder (94) to the upper outer shell (22a). The bridge (98) is positioned at the top of the upper moving cylinder (94b). The bridge (98) is positioned below the outlet cover (12).

[0206] The outlet cover (12) can be placed on top of the bridge (98). Therefore, when the moving cylinder (94) moves upward, the outlet cover (12) can also move upward. The moving cylinder (94) moves the outlet cover (12) in the up and down direction.

[0207] The moving cylinder (94) separates the outlet (12a) upward from the first discharge path (32).

[0208] The bridge (98) is connected to the upper outer shell (22a). Therefore, when the moving cylinder (94) moves up and down, the upper outer shell (22a) also moves up and down together. A plurality of bridges (98) spaced apart in the circumferential direction may be arranged between the upper outer shell (22a) and the upper moving cylinder (94b).

[0209] The humidification module generates humidified air using water supplied from a water tank (100). The humidification module includes a humidification module housing (410) that forms a space in which a humidification water tank (300, 350, see FIG. 5) is placed.

[0210] The humidification module housing (410) is placed on top of the inner housing (70). The humidification module housing (410) is placed inside the moving cylinder (94). The moving cylinder (94) is placed radially spaced apart from the humidification module housing (410).

[0211] The humidifier includes a water tank (100) forming a space for storing water, an inner shell (180) forming a space for the water tank (100) to be placed, and a middle tray (200) placed below the inner shell (180).

[0212] The water tank (100) may be in a state where the inner water tank (102) is positioned inside the outer water tank (160).

[0213] The outer tank (160) can be placed on the upper side of the middle tray (200) while positioned inside the inner shell (180). The middle tray (200) may be a structure that supports the inner shell (180), the outer tank (160), and the inner tank (102).

[0214] Accordingly, the load of the inner tank (102), outer tank (160), and inner shell (180) can be transferred to the middle tray (200).

[0215] The outer tank (160) is placed around the outer circumference of the inner tank (102).

[0216] The inner tank (102) can be positioned inside the outer tank (160). When the inner tank (102) is positioned inside the outer tank (160), the outer perimeter surface of the inner tank (102) can be positioned to contact the inner perimeter surface of the outer tank (160).

[0217] The inner shell (180) is spaced apart from the outer tank (160). The inner shell (180) is spaced apart from the tank (100). A first discharge channel (32) through which humidified air flows is formed between the inner shell (180) and the outer tank (160).

[0218] The inner shell (180) can be formed of a transparent material.

[0219] A second discharge passage (34) is formed between the outer shell (22) and the moving cylinder (94). Air rising by the blower fan (62) can flow through the second discharge passage (34).

[0220] The moving cylinder (94) and the outer shell (22) are spaced apart from each other to form a second discharge channel (34). Filtered clean air flowing through the second discharge channel (34) can flow through the blower (60).

[0221] The length of the second discharge channel (34) formed in the vertical direction can be varied. The moving cylinder (94) can move vertically to adjust the vertical length of the second discharge channel (34).

[0222] An additional flow path (33) is formed between the moving cylinder (94) and the inner shell (180). The additional flow path (33) can communicate with the first discharge flow path (32) when the moving cylinder (94) rises.

[0223] As shown in FIG. 4, the humidifier at the first position (P1) has the first discharge channel (32) and the additional channel (33) partitioned by the inner shell (180).

[0224] The outlet cover (12) can be placed over the first discharge channel (32), the second discharge channel (34), and the additional channel (33).

[0225] The outlet cover (12) can form a constant height in the vertical direction. Accordingly, a mixing channel (13) can be formed between a plurality of ribs (12b) arranged on the outlet cover (12). In the mixing channel (13), air flowing through the first discharge channel (32) can be mixed with air flowing through the second discharge channel (34).

[0226] Each of the multiple ribs (12b) is formed such that the height of the outer end is higher than the height of the inner end. Accordingly, the air flowing through the first discharge channel (32) and the second discharge channel (34) can be guided radially inward.

[0227] With reference to Fig. 5, the internal configuration of the humidifier is further explained.

[0228] The explanation focuses on the configuration not revealed in Fig. 4.

[0229] The humidification module includes a first humidification tank (300) that heats water. The humidification module includes a second humidification tank (350) that generates humidified air from water. The humidification module may include a humidification module housing (410) that covers the perimeter of the first humidification tank (300) and the second humidification tank (350).

[0230] A moving cylinder (94) is disposed around the outer circumference of the humidification module housing (410). A supply hole (412) is formed on one side of the humidification module housing (410) to supply air to the second humidification water tank (350). A guide rib (414) is disposed below the supply hole (412) to guide the air flow into the supply hole (412).

[0231] The inner housing (70) includes an upper wall (72) and an upper perimeter wall (77) that extends upward from the outer circumference of the upper wall (72), in addition to the humidification module housing (410).

[0232] The upper perimeter wall (77) is positioned on the outside of the moving cylinder (94). The inner perimeter surface of the upper perimeter wall (77) may be positioned to be in contact with the outer perimeter surface of the moving cylinder (94).

[0233] An opening is formed on one side of the inner housing (70) or moving cylinder (94) so ​​that a portion of the air flowing into the second discharge passage (34) by the blower fan (62) flows into the supply hole (412).

[0234] A first opening (78) is formed on one side of the upper edge wall (77). Through the first opening (78), a portion of the air flowing through the air passage (35) can flow into the additional passage (33). The first opening (78) is positioned below the supply hole (412). Thus, the air flowing in through the first opening (78) can flow into the supply hole (412).

[0235] It includes a perimeter wall (82) extending downward from the upper wall (72) of the inner housing (70). The perimeter wall (82) includes a curved wall (82a) that is recessed inward in an area located below the first opening (78).

[0236] The curved wall (82a) is formed on the upper part of the perimeter wall (82). The curved wall (82a) can allow a portion of the air flowing through the air passage (35) to flow into the first opening (78).

[0237] The curved wall (82a) can extend the airflow path (35) in the corresponding area. Additionally, it can guide airflow to the first opening (78) formed on the curved wall (82a).

[0238] In the area where the first opening (78) is formed, the lower part of the moving cylinder (94) may also form a second opening (95). The second opening (95) is formed above the first opening (78). Depending on the arrangement of the moving cylinder (94), the area of ​​the region formed by the first opening (78) and the second opening (95) may vary.

[0239] A handle (22c) is positioned radially outward from the guide rib (414). The handle (22c) has a structure that protrudes inward from the inner circumference surface of the outer shell (22). The handle (22c) can be positioned on the curved wall (82a).

[0240] Therefore, air flowing around the curved wall (82a) can flow into the first opening (78) by means of the structure of the handle (22c).

[0241] A display (30) is placed on one side of the case (10). The display (30) allows the user to control the power or operation of the humidifier. A display that shows the operating status of the humidifier to the user may be placed on the display (30).

[0242] Referring to Fig. 6, the state in which the moving cylinder has moved upward is explained.

[0243] The differences in relation to Figure 4 will be explained primarily.

[0244] The moving cylinder (94) can move upward by the operation of the moving motor (90). When the motor gear (91) rotates by the operation of the moving motor (90), the rack gear (92) engaged with the motor gear (91) moves up and down.

[0245] In FIG. 6, the rack gear (92) and the moving cylinder (94) are in a state where they have moved upward. The tank (100) and the inner shell (180) are fixed in position, and the moving cylinder (94) moves upward. Additionally, the outlet cover (12) placed on the moving cylinder (94) also moves upward.

[0246] The upper outer shell (22a) connected to the moving cylinder (94) also moves upward.

[0247] The outer transparent window (23) is positioned so as to be exposed to the outside. Additionally, the inner transparent window (94c) is positioned at approximately the same height as the outer transparent window (23). The inner transparent window (94c) is positioned at the same height as the outer transparent window (23), and the top and bottom of the inner transparent window (94c) are each positioned to be extended more significantly than the outer transparent window (23).

[0248] The bottom of the inner transparent window (94c) is positioned lower than the bottom of the outer transparent window (23), and the top of the inner transparent window (94c) is positioned higher than the top of the outer transparent window (23).

[0249] When the outer transparent window (23) is exposed to the outside, the inner transparent window (94c) is positioned between the outer transparent window (23) and the inner shell (180).

[0250] Therefore, when viewed from the outside, the inside of the inner transparent window (94c) can be seen through the outer transparent window (23).

[0251] It is placed on the outer perimeter of the inner shell (180) of the inner transparent window (94c).

[0252] With reference to FIGS. 7 to 9, a moving cylinder and its related configuration will be described.

[0253] The moving cylinder (94) is connected to the rack gear (92). A pair of rack gears (92) extending downward are arranged at the bottom of the moving cylinder (94). Each of the pair of rack gears (92) is arranged spaced apart in the circumferential direction.

[0254] Each of the pair of rack gears (92) is positioned in opposite directions. Each of the pair of rack gears (92) has a gear formed on a different side that meshes with the motor gear (91).

[0255] A pair of motor gears (91) that mesh with each of a pair of rack gears (92) may be spur gears. A pair of moving motors (90) that rotate the pair of motor gears (91) are fixedly positioned inside the inner housing (70).

[0256] A gear guide (83) that guides the vertical movement of the rack gear (92) is disposed in the inner housing (70). A guide groove (83a) into which a part of the rack gear (92) is inserted is formed in the gear guide (83). The guide groove (83a) is formed in the vertical direction.

[0257] The rack gear (92) includes a guide bar (92a) protruding to one side so as to be inserted into a guide groove (83a) formed in the gear guide (83).

[0258] The guide bar (92a) can move up and down along the guide home (83a).

[0259] The rack gear (92) is connected to the lower part of the moving cylinder (94).

[0260] The moving cylinder (94) includes a lower moving cylinder (94a) connected to the rack gear (92) and an upper moving cylinder (94b) spaced apart from the lower moving cylinder (94a).

[0261] The moving cylinder (94) includes an inner transparent window (94c) positioned between the lower moving cylinder (94a) and the upper moving cylinder (94b).

[0262] The lower moving cylinder (94a) is positioned around the outer perimeter of the humidification module. The lower moving cylinder (94a) is positioned inside the lower outer shell (22b). A second opening (95) is formed on one side of the lower moving cylinder (94a).

[0263] Referring to FIG. 9, the second opening (95) may be formed in an upwardly convex arch shape. The second opening (95) may be formed in the area between a pair of rack gears (92).

[0264] Referring to FIG. 8, a lower slot (94a1) is formed in the upper part of the lower moving cylinder (94a) into which the lower part of the inner transparent window (94c) is inserted.

[0265] The upper moving cylinder (94b) is positioned around the outer perimeter of the inner shell (180). The upper moving cylinder (94b) is positioned inside the upper outer shell (22a).

[0266] Referring to FIG. 8, an outlet cover (12) is placed on top of the upper moving cylinder (94b). Additionally, a water tank cover (14, see FIG. 4) is placed on top of the upper moving cylinder (94b).

[0267] At the lower part of the upper moving cylinder (94b), an upper slot (94b1) is formed into which the upper part of the inner transparent window (94c) is inserted.

[0268] A bridge (98) extending radially outward is disposed at the upper part of the upper moving cylinder (94b). The bridge (98) is connected to the upper outer shell (22a).

[0269] Multiple bridges (98) are spaced apart in the circumferential direction.

[0270] The inner transparent window (94c) is positioned between the lower moving cylinder (94a) and the upper moving cylinder (94b). The length (94cH) of the inner transparent window (94c) formed in the vertical direction is formed to be longer than the length (23H, see FIG. 18) of the outer transparent window (23) formed in the vertical direction.

[0271] The length (94bH) formed in the vertical direction of the upper moving cylinder (94b) is shorter than the length (22aH) formed in the vertical direction of the upper outer shell (22a).

[0272] Referring to FIG. 7, the upper outer shell (22a) is connected to the moving cylinder (94) through a plurality of bridges (98). Thus, the upper outer shell (22a) can move up and down together with the moving cylinder (94).

[0273] The top of the upper outer shell (22a) is located above the bridge (98). Therefore, the placement of the outlet cover (12) placed on top of the bridge (98) can be stably maintained.

[0274] With reference to FIG. 10, the structure and related configuration of the outer transparent window will be explained.

[0275] The outer transparent window (23) is placed on top of the lower outer shell (22b). The outer transparent window (23) is fixedly placed on the upper side of the lower outer shell (22b).

[0276] The diameter of the outer edge of the outer transparent window (23) is formed to be smaller than the diameter of the outer edge of the lower outer shell (22b).

[0277] A flange (23a) is positioned at the top of the outer transparent window (23). The flange (23a) is positioned at the top of the outer transparent window (23), which is formed in a ring shape. The flange (23a) is positioned to protrude outward from the outer transparent window (23). The flange (23a) can come into contact with an upper outer shell (22a, see FIG. 11) that moves in the up and down direction.

[0278] The outer transparent window (23) can be positioned radially spaced apart from the upper outer shell (22a).

[0279] A tip (23a1) protruding outward is disposed on the flange (23a). A plurality of tips (23a1) protruding outward and spaced outwardly are disposed around the perimeter of the flange (23a). The tip (23a1) protruding outward from the flange (23a) can come into contact with the inner perimeter surface of the upper outer shell (22a).

[0280] That is, the multiple tips (23a1) can minimize the contact area between the upper outer shell (22a) and the flange (23a). Therefore, the upper outer shell (22a) can move stably in the up and down direction around the outer transparent window (23).

[0281] Referring to Fig. 11, the arrangement of the flange and the upper outer shell is explained.

[0282] An upper outer shell (22a) is positioned around the flange (23a). The inner circumferential surface of the upper outer shell (22a) may come into contact with a tip (23a1) protruding outward from the flange (23a). The tip (23a1) may guide the vertical movement of the upper outer shell (22a).

[0283] Referring to FIG. 12, the opening formed in the inner housing and the moving cylinder is described.

[0284] In the inner housing (70), a curved wall (82a) is formed at the lower part of the area where the supply hole (412) of the humidification module housing (410) is formed. The curved wall (82a) is formed in a shape that is recessed inward from the upper part of the perimeter wall (82) of the inner housing (70).

[0285] In the area where the curved wall (82a) is formed, the air passage (35) can be temporarily expanded. A portion of the air flowing through the air passage (35) can flow upward along the curved wall (82a).

[0286] An opening (78, 95) is formed on the upper side of the curved wall (82a). The opening (78, 95) may refer to an opening area formed between the first opening (78) formed in the inner housing (70) and the second opening (95) formed in the moving cylinder (94).

[0287] The opening includes a first opening (78) formed in the inner housing (70) and a second opening (95) formed in the moving cylinder (94). The first opening (78) and the second opening (95) overlap in some areas.

[0288] When the moving cylinder (94) moves upward, the area of ​​the region formed by the first opening (78) and the second opening (95) increases.

[0289] The inner housing (70) includes an upper perimeter wall (77) arranged around the lower moving cylinder (94a). In the upper perimeter wall (77), a first opening (78) is formed above the curved wall (82a). The first opening (78) is formed above the curved wall (82a).

[0290] The lower moving cylinder (94a) is positioned on the inner side of the upper edge wall (77) of the inner housing (70). When the humidifier is in the first position (P1), the lower moving cylinder (94a) is positioned on the inner side of the upper edge wall (77) of the inner housing (70).

[0291] A second opening (95) is formed in the lower moving cylinder (94a). The second opening (95) is positioned in the area where the first opening (78) is located. The upper part of the second opening (95) may be formed in an arch shape.

[0292] Referring to FIGS. 13 and 14, the shape of the opening according to the arrangement of the moving cylinder is explained.

[0293] The humidification module includes an air guide (352) protruding outward from the humidification module housing (410) to allow air to flow into the second humidification tank (350). The air guide (352) is positioned on the guide rib (414). A supply hole (412) may be formed between the air guide (352) and the humidification module housing (410).

[0294] Referring to FIG. 13, at the first position (P1) of the humidifier, the opening space formed by the first opening (78) and the second opening (95) is formed below the guide rib (414).

[0295] At the first position (P1) of the humidifier, the opening space formed by the first opening (78) and the second opening (95) is formed to be relatively small. Therefore, a small amount of air can flow into the opening space formed by the first opening (78) and the second opening (95).

[0296] At the first position (P1) of the humidifier, the guide rib (414) and the air guide (352) can be covered by the lower moving cylinder (94a) and the inner transparent window (94c).

[0297] Referring to FIG. 14, at the second position (P2) of the humidifier, the opening space formed by the first opening (78) and the second opening (95) is formed above and below the guide rib (414).

[0298] At the second position (P2) of the humidifier, the guide rib (414) and the air guide (352) may be located within the opening space formed by the first opening (78) and the second opening (95).

[0299] The opening space formed by the first opening (78) and the second opening (95) at the second position (P2) of the humidifier can be formed larger than the opening space formed by the first opening (78) and the second opening (95) at the first position (P1) of the humidifier.

[0300] Accordingly, the flow rate of air flowing from the second position (P2) of the humidifier to the supply hole (412) can be formed to be above a certain level.

[0301] Additionally, a handle (22c) is positioned on one side of the air guide (352) and the guide rib (414). The handle (22c) protrudes inwardly into the lower outer shell (22b). Thus, the handle (22c) can guide air flowing upwards through the air passage (35) to the supply hole (412).

[0302] The bottom of the handle (22c) can be positioned below the guide rib (414).

[0303] With reference to FIGS. 15 and 16, the structure of the inner housing will be explained.

[0304] The inner housing (70) forms a space in which a printed circuit board (69, see FIG. 4) is placed at the bottom.

[0412] A handle protruding inward is disposed on the inner circumference of the above case. The handle is positioned to face the guide rib.

[0413] According to the humidifier of the present disclosure, there is one or more of the following effects.

[0414] First, the outer shell is positioned around the outer perimeter of the outer transparent window or has a structure that moves upward. This offers the advantage of allowing the flow of humidified air inside to be visually checked from the outside when the humidifier is operating.

[0415] In addition, when the humidifier is not in operation, an outer shell is positioned around the outer perimeter of the outer transparent window, which has the advantage of protecting the window. In other words, it prevents the transparent window from being damaged or broken by external impacts.

[0416] Second, an inner transparent window is also installed in the moving cylinder positioned inside. Additionally, when the outer transparent window is exposed, the inner transparent window is positioned in the same line of sight, allowing the flow of humidified air inside to be observed.

[0417] Third, the moving cylinder can be moved stably through the structure of the motor, gear, and rack gear positioned inside the inner housing. In addition, the outer transparent window in contact with the outer shell can maintain stable movement while minimizing friction through an outwardly protruding flange and a tip structure.

[0418] Fourth, the moving cylinder forms a flow path between the case and the air, and when the moving cylinder moves upward, the air flow path is expanded, thereby improving the straightness of the rising air.

[0419] Fifth, humidified air flowing through the first discharge channel is discharged to the outlet via the expansion channel. The expansion channel acts as a bumper for the air flowing through the first discharge channel, thereby reducing noise from escaping to the outside.

[0420] Therefore, it has the advantage of minimizing the transmission of noise generated by the humidifier to the outside.

[0421] Sixth, the air flowing through the first discharge channel forms turbulence through the diffusion channel, and its velocity is reduced before being discharged to the outside. This allows the air discharged to the outlet to be well dispersed.

[0422] However, since air from the blower fan flows upward through the additional airflow, it can facilitate the discharge of humidified air to the outlet. Through this structure, the humidified air discharged to the outlet is dispersed and diffused, allowing it to rapidly circulate over a wide area of ​​the indoor space.

[0423] Seventh, water generated inside the moving cylinder moving within the humidifier can be temporarily collected at the upper wall of the inner housing. In other words, water generated during the process of humidifying air generation and flow can be collected in a designated space.

[0424] It can prevent water from flowing into other spaces. It can control the water generated during the process of humidifying air generation and flow.

[0425] Eighth, a drain hole, a drain hose, and a drain valve are provided in the inner housing to discharge water above a certain level. Additionally, a water level sensor is placed on one side to notify the user or prevent water from overflowing from the upper wall of the inner housing.

[0426] Ninth, by directing a portion of the air flowing through the blower fan into the inner side of the moving cylinder, water generated on the inner circumference of the moving cylinder can be dried. Additionally, there is the advantage of being able to actively promote the flow of humidified air.

[0427] The effects of the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims.

[0428] 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.
