[0006] [Patent Document 1] Japanese Patent Application Publication No. 2023-034597 Summary of the Invention [Problem to be solved by the invention]

[0007] In the humidifier disclosed in Patent Document 1, when the water inlet is moved from inside the casing to outside the casing to supply water to the tank, the tank rotates relative to the casing, changing the position of the tank between a closed position where the water inlet is housed inside the casing and an open position where the water inlet is exposed to the outside of the casing.

[0008] Tanks are usually designed to hold a larger amount of water when in the closed position. In the humidifier disclosed in Patent Document 1, the tank in the open position is tilted relative to the tank in the closed position, so the tank cannot hold a sufficient amount of water when in the open position.

[0009] An object of the present disclosure is to supply a sufficient amount of water to a tank in a humidifier even when the water supply port is located in a position exposed to the outside of the casing. [Means for solving the problem]

[0040] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below, and various modifications are possible within the scope of the technical concept of the present disclosure. Since the drawings are intended to conceptually explain the present disclosure, dimensions, ratios, or numbers may be exaggerated or simplified as necessary to facilitate understanding.

[0041] (humidifier) Fig. 1 shows a perspective view of the exterior of the humidifier 1. Fig. 2 shows a front cross-sectional view of the interior of the humidifier 1 taken along line II-II when viewed from the front. In the following description, the terms "upper," "lower," "front," "rear," "right," and "left" generally refer to the directions indicated by the arrows in Fig. 1.

[0042] The humidifier (1) has a humidifying function and an air purifying function. The humidifier (1) purifies and humidifies air (A) in a target space. The humidifier (1) includes a casing (10), an air passage (P), an air purification unit (20) as an air purifying section, a fan unit (30), a humidifying unit (40) as a humidifying section, a tank (50), and a tray (70).

[0043] (Casing) As shown in Fig. 1, the casing (10) is formed in the shape of a hollow box. The casing (10) is formed in the shape of a vertically elongated rectangular parallelepiped. The casing (10) has a top plate (11a), a bottom plate (11b), a front plate (11c), a rear plate (11d), a right side plate (11e), and a left side plate (11f).

[0044] An air outlet (12) is formed in the top plate (11a). The air outlet (12) is rectangular and located slightly rearward on the top plate (11a). Two flaps (13) are provided in the air outlet (12). The flaps (13) are plate-shaped and extend from the left to the right ends of the air outlet (12). The flaps (13) open and close the air outlet (12) and adjust the direction of the air (A) being blown out.

[0045] The top plate (11a) is provided with an operation panel (14). The operation panel (14) is located toward the front of the top plate (11a). A user can operate the operation panel (14) to input the operation mode and various settings of the humidifier (1).

[0046] The right side plate (11e) is formed with a first suction port (15). The first suction port (15) is rectangular and is formed in the lower part of the right side plate (11e). An open / close lid (17) is provided on the upper part of the right side plate (11e).

[0047] The access cover (17) opens and closes an access opening (18) to the tank (50), which will be described later. The access cover (17) is detachable from the casing (10). A drawer opening (17a) is formed at the top of the access cover (17). A user places their hand on the drawer opening (17a) and pulls out the top of the access cover (17) to the right (toward the user). This tilts the top of the access cover (17) to the right, opening the access opening (18). Thereafter, the access cover (17) is removed from the casing (10) by moving it upward. The user can remove the tank (50) from the casing (10) through the access opening (18).

[0048] The left side plate (11f) is formed with a second suction port (16). The second suction port (16) is rectangular and is formed in the lower part of the left side plate (11f).

[0049] A third suction port (19) is formed at the lower end of the front plate (11c) and extends horizontally from the left to the right ends of the casing (10).

[0050] (Air passage) As shown in Fig. 2, an air passage (P) is formed inside the casing (10). The first air inlet (15), the second air inlet (16), and the third air inlet (19) form an inlet end of the air passage (P). The air outlet (12) forms an outlet end of the air passage (P).

[0051] (Air purification unit) The air purification unit (20) is located at the bottom of the air passage (P). The air purification unit (20) purifies the air drawn in through the first suction port (15), the second suction port (16), and the third suction port (19). The air purification unit (20) includes, in order from the upstream side of the air passage (P), pre-filters (21, 22), HEPA filters (23, 24) (High Efficiency Particulate Air Filters), deodorizing filters (25, 26), and discharge units (27, 28). The air (A) drawn in through the third suction port (19) flows through a relay path inside the casing (10) to the left and right HEPA filters (23, 24).

[0052] A fan unit (30) is disposed in the air passage (P) downstream of the deodorizing filters (25, 26). The first discharge unit (27) and the second discharge unit (28) generate streamer discharge on a portion of the air (A) discharged from the fan unit (30) to generate active species. The active species generated by the first discharge unit (27) and the second discharge unit (28) are discharged through a discharge path (E) to the air passage (P) upstream of the first HEPA filter (23) and the second HEPA filter (24).

[0053] (Fan unit) The fan unit (30) is disposed at the bottom of the air passage (P), below the humidification unit (40) described below. The fan unit (30) sends (transports) the air (A) through the air passage (P).

[0054] The fan unit (30) is a centrifugal fan. The fan unit (30) has a fan housing (31). The fan housing (31) accommodates an impeller and a motor that rotates the impeller. The fan unit (30) is of a double-inlet type. The axis of the fan unit (30) (the drive shaft of the motor) extends in the left-right direction. A fan inlet (32) is formed at each end of the axial direction of the fan housing (31). A fan outlet (33) is provided at the upper end of the fan housing (31). The fan outlet (33) faces upward.

[0055] When the fan unit (30) is operated, air (A) from the target space is drawn into the air passage (P) through the first inlet (15), the second inlet (16), and the third inlet (19). The air (A) that has flowed through the air passage (P) is blown out into the target space through the outlet (12).

[0056] (Humidification unit) The humidifying unit (40) humidifies the air (A) flowing through the air passage (P). Specifically, the humidifying unit (40) humidifies the air (A) purified by the air purification unit (20). The humidifying unit (40) is disposed in an upper portion of the air passage (P). The humidifying unit (40) is disposed between the fan outlet (33) of the fan unit (30) and the outlet (12) of the casing (10). The humidifying unit (40) is disposed in a humidifying space (41) located in an upper portion of the air passage (P). The humidifying unit (40) applies water (W) (see W in FIG. 12 ) to the air (A) flowing through the air passage (P).

[0057] 3 is a right side cross-sectional view taken along line III-III of the interior of the humidifier (1) as viewed from the right side. The humidifier unit (40) includes a humidification rotor (42) and dampers (43, 44). The humidifier (1) includes a tank (50) and a tray (70). The tank (50) and the tray (70) are attached to the humidifier unit (40).

[0058] The tank (50) is a container that stores water (W) for humidification. The tank (50) supplies the water (W) in the tank (50) to the tray (70) as needed. The tank (50) can be moved in and out of the casing (10) through the access opening (18). Details of the tank (50) will be described later.

[0059] The tray (70) stores the water (W) supplied from the tank (50). The tray (70) supplies the water (W) to the water absorbing member of the humidification rotor (42). The tray (70) is a container that is open upward.

[0060] The humidification rotor (42) includes a water-absorbing member. The humidification rotor (42) applies water (W) contained in the water-absorbing member to the air (A) in the humidification space (41) in the air passage (P). The humidification rotor (42) divides the humidification space (41) into a primary space (41a) and a secondary space (41b). The primary space (41a) is formed upstream of the humidification rotor (42). The secondary space (41b) is formed downstream of the humidification rotor (42).

[0061] The humidification rotor (42) is disk-shaped and has a drive shaft (42a) at its center. The drive shaft (42a) extends across both the primary space (41a) and the secondary space (41b). The drive shaft (42a) is rotatably supported by two shaft supports (45) provided on the tray (70). The humidification rotor (42) is rotated about the drive shaft (42a) by a motor (not shown).

[0062] A middle plate (80) is housed within the casing (10). The middle plate (80) extends in the front-rear and left-right directions. The middle plate (80) separates the fan unit (30) and the humidification unit (40) into upper and lower sections. The tray (70) is placed on the middle plate (80). A hole (80a) for circulating air (A) is formed in a portion of the middle plate (80) facing the fan outlet (33) of the fan unit (30). The tray (70) will be described in detail later.

[0063] The humidification space (41) is provided with a first damper (43) and a second damper (44). The first damper (43) is disposed in the air passage (P) between the fan unit (30) and the secondary space (41b). The second damper (44) is disposed in the air passage (P) between the primary space (41a) and the air outlet (12). The first damper (43) and the second damper (44) open and close in conjunction with each other. Specifically, when the first damper (43) closes, the second damper (44) also closes. When the first damper (43) opens, the second damper (44) also opens.

[0064] The first damper (43) and the second damper (44) change the flow of air (A) in the air passage (P) in the humidification space (41). As shown in Fig. 3, when both the first damper (43) and the second damper (44) are closed, the air (A) blown out from the fan unit (30) flows into the primary space (41a), passes through the humidification rotor (42), and then flows out into the secondary space (41b) and is discharged through the outlet (12). At this time, the humidified air (A) is discharged through the outlet (12).

[0065] On the other hand, when both the first damper (43) and the second damper (44) are open, the air (A) blown out from the fan unit (30) bypasses the humidification rotor (42) and flows through the primary space (41a) and the secondary space (41b) toward the outlet (12). At this time, the air (A) is discharged from the outlet (12) with almost no humidification.

[0066] (Tanks and trays) The tank (50) and the tray (70) will be described in detail.

[0073] As shown in Fig. 8, a locking recess (56) serving as a locking portion is provided on the right surface of the grip portion (55a) of the handle (55) of the tank (50). The locking recess (56) is recessed leftward with respect to the right surface of the grip portion (55a) of the handle (55) (see the simplified cross-sectional view in Fig. 5).

[0074] 10 shows the tank (50) removed from the tray (70). The bottom (57) of the tank (50) is provided with legs (58). The bottom (57) of the tank (50) refers to the area of ​​the tank (50) that extends from the lower end to a position slightly above the lower end. More specifically, the legs (58) are provided on the bottom wall (50e) of the tank (50) and extend downward from the bottom wall (50e).

[0075] The legs (58) include a first leg (58a), a second leg (58b), and a third leg (58c). The first leg (58a) is provided on the left side and toward the rear of the bottom wall portion (50e). The second leg (58b) is provided on the left-right center and toward the front of the bottom wall portion (50e). The third leg (58c) is provided on the right side and toward the rear of the bottom wall portion (50e). The three legs (58) (the first leg (58a), the second leg (58b), and the third leg (58c)) support the tank (50) at three points on a horizontal surface (G) such as a floor or a table.

[0076] 10, a first guided projection (59a) is provided on the bottom (57) of the tank (50). More specifically, the first guided projection (59a) is provided on the lower left end of the front wall (50a) of the tank (50). The first guided projection (59a) extends forward from the front wall (50a).

[0078] As shown in Fig. 7, a contactable projection (60) is provided on the upper portion (54) of the tank (50). More specifically, the contactable projection (60) is provided on the left end portion of the lid (52) of the tank (50). The contactable projection (60) protrudes upward from the upper surface of the lid (52). The upper end of the contactable projection (60) is located above the upper end of the lid (52).

[0079] 12, the tank (50) includes an outlet (61), a valve (62), a spring (63) as an elastic body, and a cylindrical portion (64). The outlet (61) is provided in the bottom portion (57) of the tank (50). More specifically, the outlet (61) is provided in the center of the bottom wall portion (50e) of the tank (50) and passes through the bottom wall portion (50e) in the vertical direction.

[0080] The valve (62) includes a valve element (62a), a valve stem (62b), and a disk portion (62c). The valve element (62a) is formed in a conical shape that bulges downward. The valve element (62a) is disposed above the outlet (61). The valve element (62a) closes the outlet (61) by contacting the upper opening edge of the outlet (61). The valve stem (62b) has a long, thin rod shape and extends downward from the valve element (62a). The disk portion (62c) has a larger diameter than the valve stem (62b) and is fixed to the lower end of the valve stem (62b). The spring (63) is a coil spring and is disposed around the valve stem (62b) between the valve element (62a) and the disk portion (62c). The valve stem (62b) passes through the spring (63).

[0081] The valve (62) moves between an upper open position (J1) and a lower closed position (J2) to open and close the outlet (61). When the valve (62) is in the upper open position (J1), the valve element (62a) moves upward away from the upper opening edge of the outlet (61) to open the outlet (61). When the valve (62) is in the lower closed position (J2), the valve element (62a) comes into contact with the upper opening edge of the outlet (61) to close the outlet (61). A spring (63) biases the valve (62) toward the lower closed position (J2). Specifically, the spring (63) pushes the valve (62) downward toward the lower closed position (J2).

[0082] The cylindrical portion (64) extends downward from the bottom (57) of the tank (50). More specifically, the cylindrical portion (64) extends downward from the bottom wall (50e) of the tank (50). The cylindrical portion (64) surrounds the valve stem (62b) and the disk portion (62c) of the valve (62). The cylindrical portion (64) forms the second leg (58b) (see FIG. 10).

[0083] As shown in FIG. 12, the lower end (62d) of the disc portion (62c) of the valve (62) in the lower closed position (J2) is located higher than the lower end (64a) of the cylindrical portion (64).

[0084] As shown in Fig. 10, a horizontal bottom (65) is provided at the bottom (57) of the tank (50). More specifically, the horizontal bottom (65) is formed by a part of the lower surface of the cylindrical portion (64). The horizontal bottom (65) extends straight from the left side to the right side in the horizontal direction (H).

[0085] (tray) As shown in Fig. 11, the tray (70) includes a first tray (71), a second tray (72), two communication passages (73), and a float mechanism (77) serving as a push-up mechanism. The first tray (71) is disposed in the front. The second tray (72) is disposed in the rear. The two communication passages (73) connect the left and right ends of the first tray (71) and the left and right ends of the second tray (72) in the front-rear direction.

[0086] The first tray (71) is shaped like a box that is open upward. The first tray (71) is long in the left-right direction and short in the front-to-back direction. The first tray (71) includes a front wall (71a), a rear wall (71b), a right wall (71c), a left wall (71d), and a bottom wall (71e). An opening (74) is provided at the upper end of the first tray (71).

[0087] The first tray (71) of the tray (70) accommodates the tank (50). The tank (50) is placed on the bottom wall (71e) of the first tray (71) of the tray (70). The water (W) flowing out of the tank (50) through the outlet (61) of the tank (50) flows into the first tray (71) of the tray (70). In other words, the water (W) flows out of the tank (50) through the outlet (61) of the tank (50) into the first tray (71) of the tray (70).

[0088] The second tray (72) is shaped like a box that is open upward. The second tray (72) is long in the left-right direction and short in the front-rear direction. An opening is provided at the upper end of the second tray (72). The second tray (72) of the tray (70) accommodates the humidification rotor (42) of the humidification unit (40). The water (W) that flows out of the tank (50) into the first tray (71) is sent to the second tray (72) through the communication passage (73) and supplied to the humidification rotor (42).

[0089] The gap (79) between the first tray (71) and the second tray (72) is open at the top and bottom and faces the fan outlet (33) of the fan unit (30) (see FIG. 3). As shown in Figures 5 and 11, a first slope (75) is provided on the front edge of the opening (74) at the upper end of the first tray (71) of the tray (70). The first slope (75) extends obliquely upward from the left to the right with respect to the horizontal direction (H). As shown in Figure 5, the bottom (57) of the tank (50) is placed on the first slope (75). More specifically, the first guided projection (59a) of the tank (50) is placed on the first slope (75).

[0090] 5, a first horizontal portion (75a) is provided at the right end of the first slope (75). The first horizontal portion (75a) extends straight in the horizontal direction (H) from the left to the right.

[0091] 5, a first positioning recess (75b) is provided in the first horizontal portion (75a) of the first tray (71) of the tray (70). The first positioning recess (75b) is recessed downward with respect to the first horizontal portion (75a).

[0092] As shown in Figures 6 and 11, a second slope (76) is provided at the rear edge of the opening (74) at the upper end of the first tray (71) of the tray (70). The second slope (76) extends obliquely upward from the left to the right with respect to the horizontal direction (H). As shown in Figure 6, the bottom (57) of the tank (50) is placed on the second slope (76). More specifically, the second guided projection (59b) of the tank (50) is placed on the second slope (76).

[0093] 6, a second horizontal portion (76a) is provided at the right end of the second slope (76). The second horizontal portion (76a) extends straight in the horizontal direction (H) from the left to the right.

[0094] 6, a second positioning recess (76b) is provided in the second horizontal portion (76a) of the first tray (71) of the tray (70). The second positioning recess (76b) is recessed downward with respect to the second horizontal portion (76a).

[0095] As shown in Fig. 11, two horizontal placement portions (78) are provided on the right edge of the opening (74) at the upper end of the first tray (71) of the tray (70). The two horizontal placement portions (78) are arranged between the first slope (75) and the second slope (76) in the front-rear direction. The two horizontal placement portions (78) are parallel to each other and extend straight in the horizontal direction (H) from left to right.

[0096] As shown in FIG. 12, the float mechanism (77) is disposed at the bottom of the first tray (71) of the tray (70). The float mechanism (77) includes a float body (77a), a floater (77b), and a contact member (77c). The float body (77a) extends from the left inner surface of the first tray (71) toward the center. The floater (77b) is fixed to the left end of the float body (77a). The floater (77b) floats on the water (W) stored in the first tray (71) and moves up and down depending on the height of the water surface. The contact member (77c) is fixed to the right end of the float body (77a). The contact member (77c) is disposed directly below the valve (62) of the tank (50). The float body (77a) is provided with a rotation shaft extending in the front-rear direction, and is supported rotatably with respect to the first tray (71).

[0097] According to the seesaw principle, when the floater (77b) at the left end of the float body (77a) rises, the contact member (77c) at the right end of the float body (77a) descends, and when the floater (77b) at the left end of the float body (77a) descends, the contact member (77c) at the right end of the float body (77a) rises.

[0098] The contact member (77c) of the float mechanism (77) contacts the lower end (62d) of the disk portion (62c) of the valve (62) inside the cylindrical portion (64) of the tank (50). The contact member (77c) of the float mechanism (77) enters the inside of the cylindrical portion (64) from below to above. The contact member (77c) of the float mechanism (77) pushes the valve (62) upward to the open position inside the cylindrical portion (64) of the tank (50).

[0099] (Top cover) As shown in Fig. 5, the casing (10) is provided with an upper cover (81) as a wall. The upper cover (81) is fixed to the inside of the casing (10) via a bracket or the like (not shown). The upper cover (81) covers the tank (50) from above. The upper cover (81) covers the tank (50) from above on both the left and right sides. The upper cover (81) extends obliquely upward with respect to the horizontal direction (H) from the left to the right so as to correspond to the first slope (75) and the second slope (76).

[0100] The underside of the left end of the top cover (81) faces closely to the upper end of the contactable projection (60) provided on the lid (52) of the upper part (54) of the tank (50). The underside of the central part of the top cover (81) faces closely to the upper end of the handle (55) provided on the upper part (54) of the tank (50). The underside of the right end of the top cover (81) faces, at a distance, to the upper surface of the right end of the lid (52) of the upper part (54) of the tank (50).

[0101] (Lock lever) A locking lever (82) serving as a locking portion is provided at the right end of the upper cover (81) of the casing (10). The locking lever (82) constitutes the fixed portion (F). In other words, the fixed portion (F) is the locking lever (82). It can also be said that the upper cover (81) of the casing (10) is provided with the fixed portion (F). The locking lever (82) is rotatable about a pivot shaft (82a) extending forward and backward. A locking claw (82b) is provided at the tip of the locking lever (82). The locking claw (82b) of the locking lever (82) enters from right to left into the locking recess (56) provided in the handle (55) of the tank (50) and locks (hooks) the locking recess (56). The locking lever (82) corresponds to the locking recess (56). In other words, the locked recess (56) corresponds to the locking lever (82).

[0102] (Convex part) Three protrusions (83) are provided on the lower surface of the upper cover (81) (see FIG. 13). The protrusions (83) protrude downward from the lower surface of the upper cover (81). The three protrusions (83) are arranged side by side near the left end of the upper cover (81). Note that in FIG. 13, the protrusions (83) are exaggerated and drawn larger than they actually are to make them easier to understand.

[0103] (Movement of tank between first and second positions) The tank (50) is movable between a first position (K1) on the left side and a second position (K2) on the right side. The above-mentioned Figures 5 to 12 show the tank (50) in the first position (K1). The above-mentioned Figures 13 to 15 show the tank (50) in the second position (K2). Figure 13 corresponds to Figure 5, Figure 14 corresponds to Figure 6, and Figure 15 corresponds to Figure 7.

[0104] As shown in FIG. 5, the water supply port (53) of the tank (50) is housed in the interior (I) of the casing (10) at the first position (K1). Specifically, the casing (10) includes a right side plate (11e) as a right case side surface. The right side plate (11e) faces straight in the horizontal direction (H). The right side plate (11e) is provided with an access opening (18) as an opening. The access opening (18) is covered with an openable lid (17). At the first position (K1), the water supply port (53) of the tank (50) is located closer to the interior (I) of the casing (10) (to the left) than the access opening (18).

[0105] As shown in Figure 13, the water supply port (53) of the tank (50) is exposed to the outside (O) of the casing (10) in the second position (K2). In the second position (K2), the opening / closing cover (17) is removed from the right side plate (11e) to open the access opening (18). In the second position (K2), the water supply port (53) of the tank (50) is located closer to the outside (O) of the casing (10) (to the right) than the access opening (18).

[0106] 5 and 13, the tank (50) moves in parallel to the left and right between the first position (K1) and the second position (K2) without changing its posture, which refers to the inclination of the tank (50) relative to the tray (70).

[0107] 5 and 13, the direction of movement (M) of the tank (50) between the first position (K1) and the second position (K2) includes a horizontal component (H). The direction of movement (M) includes a first direction of movement (M1) from the first position (K1) to the second position (K2) and a second direction of movement (M2) from the second position (K2) to the first position (K1).

[0108] As shown in FIGS. 5 and 13, the first movement direction (M1) in which the tank (50) moves from the first position (K1) to the second position (K2) is obliquely upward.

[0109] Specifically, as described above, the first tray (71) of the tray (70) is provided with a first slope (75) on the front side and a second slope (76) on the rear side, as shown in Figures 5, 6, 13, and 14. The first slope (75) extends obliquely upward from the first position (K1) toward the second position (K2). The second slope (76) extends obliquely upward from the first position (K1) toward the second position (K2).

[0110] The tank (50) moves obliquely upward from the first position (K1) toward the second position (K2) along the first slope (75) and the second slope (76). As shown in Figures 5 and 13, the front first guided projection (59a) on the bottom (57) of the tank (50) comes into contact with the first slope (75) and slides on the first slope (75). As shown in Figures 6 and 14, the rear second guided projection (59b) on the bottom (57) of the tank (50) comes into contact with the second slope (76) and slides on the second slope (76).

[0111] As shown in FIG. 13, when the tank (50) is in the second position (K2), the horizontal bottom (65) of the bottom (57) of the tank (50) rides on the horizontal placement portion (78) of the tray (70) and is placed on the horizontal placement portion (78).

[0112] As shown in Fig. 13, a first guided projection (59a) is provided on the front side of the bottom (57) of the tank (50). A first horizontal portion (75a) is provided on the end of the first slope (75) of the tray (70) on the second position (K2) side (right side). A first positioning recess (75b) is provided on the first horizontal portion (75a). When the tank (50) is in the second position (K2), the first guided projection (59a) of the tank (50) is placed on the first horizontal portion (75a) of the tray (70) and is fitted into and positioned in the first positioning recess (75b) of the tray (70).

[0113] As shown in Fig. 14, a second guided projection (59b) is provided on the rear side of the bottom (57) of the tank (50). A second horizontal portion (76a) is provided on the end of the second slope (76) on the second position (K2) side (right side) of the tray (70). A second positioning recess (76b) is provided on the second horizontal portion (76a). When the tank (50) is in the second position (K2), the second guided projection (59b) of the tank (50) is placed on the second horizontal portion (76a) of the tray (70) and is fitted into and positioned in the second positioning recess (76b) of the tray (70).

[0114] 13, the upper cover (81) covering the tank (50) from above extends obliquely upward with respect to the horizontal direction (H) from the first position (K1) toward the second position (K2). The upper cover (81) guides the movement of the tank (50) from above between the first position (K1) and the second position (K2).

[0115] The convex portion (83) protruding downward from the lower surface of the upper cover (81) comes into contact with the contacted projection (60) on the upper portion (54) of the tank (50) that moves obliquely downward from the second position (K2) to the first position (K1).

[0116] The handle 55 on the top 54 of the tank 50 is provided with a locking recess 56 (see FIG. 8). As shown in FIG. 13, the locking recess 56 is locked (hooked) by the locking claw 82b of the locking lever 82, thereby fixing the tank 50 at the second position K2.

[0117] The locking lever (82) serving as the fixing part (F) fixes the tank (50) in the same position at the second position (K2) as it was in the first position (K1). In other words, the locking lever (82) serving as the fixing part (F) fixes the tank (50) in the same position at the second position (K2) as it was in the first position (K1). The "same position" means, for example, that the inclination of the tank (50) relative to the tray (70) is approximately the same. The water supply port (53) of the tank (50) is approximately horizontal with respect to the horizontal plane (G) at the first position (K1) and the second position (K2).

[0118] (Standing tank) As shown in Fig. 10, legs 58 are provided on the bottom 57 of the tank 50. The legs 58 allow the tank 50, removed from the tray 70, to stand on its own on the horizontal surface G in the same position as in the first position K1.

[0119] (inhibition mechanism) As shown in Fig. 8, the humidifier (1) includes a suppression mechanism (90). The suppression mechanism (90) includes a first stopper (91), a second stopper (92), and a third stopper (93).

[0120] The first stopper (91) extends upward from the middle plate (80) to the right of the first tray (71) of the tray (70). The length of the first stopper (91) in the vertical direction is a first dimension (L1). The second stopper (92) is formed by the lower surface of the upper cover (81). A gap of a second dimension (L2) is formed in the vertical direction between the second stopper (92) (the lower surface of the upper cover (81)) and the upper end of the handle (55) of the tank (50). The third stopper (93) is disposed above the right end of the second tray (72) of the tray (70). A gap of a third dimension (L3) is formed in the vertical direction between the lower end of the third stopper (93) and the upper end of the right end of the tray (70).

[0121] The second dimension (L2) is smaller than the first dimension (L1). If an attempt is made to forcibly remove the tray (70) together with the tank (50) from the casing (10) while the tank (50) is not detached from the tray (70) and to lift the tray (70) above the first stopper (91), the handle (55) of the tank (50) will come into contact with the second stopper (92).

[0122] The third dimension (L3) is greater than the first dimension (L1). When the tank (50) is removed from the tray (70), even if the tray (70) is lifted above the first stopper (91) in an attempt to remove the tray (70) alone from the casing (10), the upper end of the right end of the tank (50) does not come into contact with the third stopper (93).

[0123] In this manner, the restricting mechanism (90) restricts the tray (70) from being removed from the casing (10) when the tank (50) is not removed from the tray (70), and the restricting mechanism (90) allows the tray (70) to be removed from the casing (10) when the tank (50) is removed from the tray (70).

[0124] (Action and effect) The tank (50) is normally designed to hold a larger amount of water (W) when in a first position (K1) where the water supply port (53) is housed inside (I) of the casing (10). According to this embodiment, the tank (50) is fixed by a fixing portion (F) in the same position as in the first position (K1) when in a second position (K2) where the water supply port (53) is exposed to the outside (O) of the casing (10).

[0125] The attitude of the tank (50) at the second position (K2) can be fixed in the same position as the attitude of the tank (50) at the first position (K1). In the humidifier (1), even when the water supply port (53) is at the second position (K2) exposed to the outside (O) of the casing (10), a sufficient amount of water (W) can be supplied to the tank (50).

[0126] The tank (50) moves parallel between the first position (K1) and the second position (K2) without changing its posture, and the posture of the tank (50) at the second position (K2) can be easily made the same as the posture of the tank (50) at the first position (K1).

[0127] The direction of movement (M) in which the tank (50) moves between the first position (K1) and the second position (K2) includes a horizontal component (H). The tank (50) can be easily moved between the first position (K1) and the second position (K2).

[0128] The first movement direction (M1) in which the tank (50) moves from the first position (K1) to the second position (K2) is obliquely upward with respect to the horizontal direction (H). When the tank (50) moves from the first position (K1) to the second position (K2), the tank (50) is lifted upward, which prevents the bottom (57) of the tank (50) from interfering with an obstruction provided on the tray (70).

[0129] The first slope (75) and the second slope (76) extend obliquely upward with respect to the horizontal direction (H) from the first position (K1) side toward the second position (K2) side. By placing the first guided projection (59a) and the second guided projection (59b) on the bottom portion (57) of the tank (50) on the first slope (75) and the second slope (76), the tank (50) can be easily moved obliquely upward with respect to the horizontal direction (H) from the first position (K1) side toward the second position (K2) side.

[0130] When the tank (50) is in the second position (K2), the horizontal bottom portion (65) of the bottom portion (57) of the tank (50) rests on the horizontal placement portion (78) of the tray (70). At the second position (K2), the horizontal bottom portion (65) of the tank (50) and the horizontal placement portion (78) of the tray (70) are in line contact or surface contact with each other, so that the tank (50) can be stably held at the second position (K2).

[0131] The contact member (77c) of the float mechanism (77) of the tray (70) enters the inside of the cylindrical portion (64) at the bottom (57) of the tank (50) and pushes up the valve (62). By moving the tank (50) obliquely upward from the first position (K1) to the second position (K2), the tank (50) is lifted upward, thereby preventing interference between the contact member (77c) of the float mechanism (77) and the cylindrical portion (64).

[0132] The protrusions (83) protruding downward from the lower surface of the upper cover (81) come into contact with the contacted projections (60) on the upper portion (54) of the tank (50) as it moves obliquely downward from the second position (K2) to the first position (K1). This reduces the speed at which the tank (50) moves obliquely downward from the second position (K2) to the first position (K1). The protrusions (83) function as a brake.

[0133] The locking lever (82) as the fixing portion (F) is locked in the locking recess (56) in the upper portion (54) of the tank (50), which makes it easy to fix the tank (50) in the second position (K2).

[0134] Since the locking lever 82 is provided on the upper cover 81 and the locking recess 56 is provided on the handle 55 on the upper portion 54 of the tank 50, the locking lever 82 and the locking recess 56 can be brought closer to each other, thereby preventing the size of the locking lever 82 from becoming larger.

[0135] The access opening (18) makes it easy to insert and remove the tank (50) into and from the casing (10).

[0136] The legs (58) allow the tank (50) removed from the tray (70) to stand upright on the horizontal surface (G) in the same position as in the first position (K1). Even when the tank (50) is removed from the tray (70), a sufficient amount of water (W) can be supplied to the tank (50). Furthermore, when supplying water after removing the tank (50), there is no need to stabilize the tank (50) by using hands or other means, improving the ease of water intake.
