[0003] [Patent Document 1] JP 2016-3842 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the humidifier of Patent Document 1, the user removes the tank from the humidifier body and fills the tank with water in a kitchen or bathroom with a faucet. Although the tank can be filled with water directly from the faucet in this way, the tank needs to be removed from the humidifier body and then refilled with water and then attached to the humidifier body, which poses an issue with the conventional method in that it is time-consuming for the user to fill the tank with water.

[0005] An object of the present disclosure is to provide a humidifier that allows water to be easily supplied to a tank. [Means for solving the problem]

[0006] A first aspect of the present disclosure is a humidification device comprising a casing (10), an air passage (AP) formed in the casing (10), a humidification section (U3) that humidifies air circulating within the air passage (AP), a tray (50) that supplies water to the humidification section (U3), a tank (60) that supplies water to the tray (50), and a water supply port (67) that communicates with the tank (60) and supplies water into the tank (60) from the outside, the water supply port (67) being positioned so as to be exposed to the outside of the casing (10).

[0007] In the first aspect, the water inlet (67) is exposed to the outside of the casing (10), so that water can be supplied to the tank (60) directly through the water inlet (67) without removing the tank (60) from the humidifier body.

[0008] A second aspect of the present disclosure relates to the first aspect, The water supply port (67) changes between a first position where it is exposed to the outside of the casing (10) when supplying water and a second position where it is accommodated inside the casing (10) when not supplying water.

[0009] In the second mode, water can be supplied into the tank (60) by putting the water supply port (67) into the first position depending on the timing of supplying water. In the second position, the water supply port (67) is not exposed to the outside of the casing (10), and therefore, intrusion of dust and the like into the tank (60) through the water supply port (67) can be suppressed.

[0010] A third aspect of the present disclosure relates to the second aspect, The casing (10) further includes an openable and closable door portion (18) that constitutes part of the side surface thereof, the water supply port (67) is disposed inside the door portion (18), the first position is a state in which the door portion (18) is open, and the second position is a state in which the door portion (18) is closed.

[0011] In the third aspect, the water supply port (67) can be changed between a first position and a second position by opening and closing the door portion (18). When pouring water into the water supply port using a container such as a kettle, since the door portion (18) is located on the side surface of the casing (10), it is not necessary to lift the kettle, making the water supply operation easier than when water is supplied from the top surface of the casing (10), for example.

[0012] A fourth aspect of the present disclosure is the water supply device of the third aspect, further comprising an openable and closable lid member (68) disposed on the water supply port (67).

[0013] In the fourth aspect, the cover member (68) is opened and closed so that the water supply port (67) is exposed to the outside only when water is being supplied, thereby preventing water from splashing to the outside from the water supply port (67) when the cover member (68) is closed.

[0014] A fifth aspect of the present disclosure relates to the fourth aspect, The cover member (68) changes so that the water supply port (67) is open in the first position and the water supply port (67) is closed in the second position.

[0015] In the fifth aspect, in the second position, intrusion of dust into the water supply port (67) can be suppressed.

[0016] A sixth aspect of the present disclosure is the method according to the fifth aspect, In the first position, the cover member (68) is biased to maintain the water supply port (67) in an open state, and prevents the cover member (68) from changing from the first position to the second position.

[0017] In the sixth aspect, water can be supplied without having to open the lid member (68) by hand. In addition, since the change from the first position to the second position is restricted, it is possible to prevent the first position from changing to the second position while water is being supplied.

[0018] A seventh aspect of the present disclosure is the third to sixth aspects, The water supply port (67) is provided in the tank (60), the tank (60) is rotatably supported by the casing (10), and the water supply port (67) changes between the first position and the second position as the tank (60) rotates.

[0019] In the seventh aspect, the water supply port (67) can be moved between the first position and the second position simply by rotating the tank (60).

[0020] The eighth aspect of the present disclosure relates to the seventh aspect, The tank (60) further includes a regulating member (70) that regulates the tank (60) from further tilting from the first position toward the first direction when a direction in which the tank (60) rotates from the second position to the first position is defined as a first direction and a direction in which the tank (60) rotates from the first position to the second position is defined as a second direction.

[0021] In the eighth aspect, the restricting member (70) can restrict the tank (60) from tilting further in the first direction from the first position, thereby preventing water in the tank (60) from spilling out of the water inlet (67).

[0022] A ninth aspect of the present disclosure is the method according to the seventh or eighth aspect, The water supply device further includes an overflow prevention mechanism (K) that guides water overflowing from the water supply port (67) to the tray (50).

[0023] In the ninth aspect, for example, even if water overflows from the water supply port (67) during water supply, the water is guided into the tray (50), thereby preventing the water from entering the mechanical parts inside the casing (10). As a result, breakdowns of the humidifier can be prevented.

[0024] A tenth aspect of the present disclosure is the method according to the ninth aspect, The tank (60) is arranged so that a first side surface (61a) of the tank (60) is aligned along the inner surface of the door portion (18), and the overflow suppression mechanism (K) includes a passage portion (P) formed between the inner surface of the door portion (18) and the first side surface (61a), and a pair of wall portions (19) provided on the door portion (18) along the passage portion (P) so as to cover both ends of the first side surface (61a).

[0025] In the tenth aspect, water spilled between the door portion (18) and the first side surface (61a) of the tank (60) can flow through the passage portion (P) into the tray (50). Water spilled on both sides of the first side surface (61a) can flow into the tray (50) through the inner surface of the wall portion (19).

[0026] An eleventh aspect of the present disclosure is the first to tenth aspects, The tank (60) is configured to be detachable from the casing (10).

[0027] In the eleventh embodiment, the tank (60) can be removed to supply water, which allows water to be supplied in two ways, depending on the situation: by supplying water directly to the tank (60) or by removing the tank (60) to supply water.

[0028] A twelfth aspect of the present disclosure is the first to eleventh aspects, The tank (60) is provided with an opening / closing mechanism (66) that communicates with the tray (50), and water is supplied to the tray (50) when the opening / closing mechanism (66) is in an open state, and water is not supplied to the tray (50) when the opening / closing mechanism (66) is in a closed state.

[0029] In the twelfth aspect, for example, when the tank (60) is full of water, the opening and closing mechanism (66) is closed, so that water is not absorbed into the tray (50). This makes it possible to prevent water from overflowing from the tray (50).

[0030] A thirteenth aspect of the present disclosure is the first to twelfth aspects, The water supply port (67) has an inlet (67a) through which water flows in and an outlet (67b) through which the water flowing in from the inlet (67a) flows out into the tank (60), and the opening area of ​​the outlet (67b) is smaller than the opening area of ​​the inlet (67a).

[0031] In the thirteenth aspect, the outlet (67b) is made smaller than the inlet (67a), so that water leakage from the water supply port (67) due to splashing of water flowing into the tank (60) can be suppressed. [Brief description of the drawings]

[0035] The humidifier (1) mainly comprises a casing (10), a fan unit (U1), an air purifying unit (U2), a humidifying unit (U3), and a water supply unit (U4). The humidifier (1) transports sucked indoor air through the fan unit (U1), the air purifying unit (U2), and the humidifying unit (U3) in that order, and blows the air out into the room. Each component will be described in detail below.

[0036] (2) Casing The casing (10) is formed in a vertically long box shape. An air passage (AP) formed in the vertical direction is provided inside the casing (10). In the air passage (AP), an air blowing chamber (2), an air cleaning chamber (3), and a humidification chamber (4) are arranged in this order from bottom to top.

[0037] The casing (10) has a top plate (11), a bottom plate (12), and four side plates (13). An operation panel (16) is provided on the top plate (11). The operation panel (16) is equipped with a power switch for selecting whether to operate or stop the humidifier (1), a button for selecting whether to start or stop the humidification function, and the like. The operation panel (16) includes a display (not shown) on which predetermined information is displayed. Examples of the predetermined information include the current indoor humidity and water level information in a tray (50) described below. In the following description, "front," "rear," "right," and "left" refer to directions when the operation panel (16) is viewed from the front.

[0038] An air outlet (14) is provided in the top plate (11). The air outlet (14) is formed behind the operation panel (16). The air outlet (14) is formed across the entire area in the left-right direction. The air outlet (14) is provided with two flaps (17). Each flap (17) is formed in a horizontally long rectangle. The two flaps (17) are arranged side by side in the front-rear direction. Each flap (17) is rotatably supported by the top plate (11) and adjusts the opening / closing and air direction of each air outlet (14).

[0039] The four side panels (13) are a front panel (13a), a rear panel (13b), a right side panel (13c), and a left side panel (13d). An inlet (15) is provided at the lower part of each of the right side panel (13c) and the left side panel (13d). The inlet (15) is connected to the air passage (AP) and draws in air from the indoor space. Specifically, each inlet (15) is provided below the center of each side panel (13c, 13d) and over substantially the entire area of ​​each side panel (13c, 13d) in the width direction (front-rear direction). A prefilter (not shown) is provided in each inlet (15). The prefilter is provided so as to cover each inlet (15). This allows relatively large dust particles and the like to be captured. The bottom panel (12) closes the lower end of the side panel (13).

[0040] (2-1-1) Side door The casing (10) is provided with a side door (18). The side door (18) is an example of a door portion (18) of the present disclosure. The side door (18) constitutes a part of the side of the casing (10). Specifically, the side door (18) constitutes a part of the right side panel (13c). The side door (18) is formed in a rectangular shape and constitutes a part that is located above the center of the right side panel (13c) and covers substantially the entire area of ​​the right side panel (13c) in the width direction (front-rear direction).

[0041] The side door (18) is configured to be openable and closable (see FIG. 3). Specifically, the lower end of the side door (18) is rotatably supported within the casing (10), and by pulling the handle (18a) of the side door (18) toward the user, the side door (18) tilts toward the user and the upper end is opened. When the side door (18) is fully open, it is tilted 25 to 45 degrees from the fully closed state (when the side door (18) is vertical).

[0042] In the following description, the state in which the side door (18) is open is referred to as the first position (the state shown in FIG. 3(b)), and the state in which the side door (18) is closed is referred to as the second position (the state shown in FIG. 3(a)). The open position refers to a state in which the side door (18) is fully open, and the closed position refers to a state in which the side door (18) is fully closed. The direction in which the side door (18) rotates so as to incline from the second position to the first position is referred to as the first direction, and the direction in which the side door (18) rotates from the first position to the second position is referred to as the second direction. Here, the fully open state of the side door (18) refers to a state in which the side door (18) does not rotate any further in the first direction and is supported in the first position. Note that the first position may be a state in which at least a part of the water supply port (67) is exposed to the outside of the casing (10) in a state in which water can be supplied from the outside in a first water supply method described later.

[0043] (3) Fan unit The fan unit (U1) is disposed in the blower chamber (2). The fan unit (U1) is disposed at a position facing the inlet (15). The fan unit (U1) includes a fan (21) and a fan motor (22).

[0044] The fan (21) is a sirocco fan. The fan (21) is rotated by being driven by a fan motor (22). The fan (21) draws indoor air into the ventilation chamber (2) through the suction ports (15) and transports the air toward the air outlet (14) through the air purification chamber (3) and then through the humidification chamber (4). In this manner, the fan (21) transports air in the air passage (AP) from the suction port (15) toward the air outlet (14).

[0045] The fan (21) is capable of varying the volume of airflow. Specifically, the fan motor (22) is configured to have a variable rotation speed. The rotation speed of the fan motor (22) can be switched between a plurality of stages. The rotation speed of the fan motor (22) is controlled by the control unit (C).

[0046] (4) Air purifier unit The air purification unit (U2) is disposed in the air purification room (3). The air purification unit (U2) has a dust collecting filter (31) and a deodorizing filter (32). The dust collecting filter (31) and the deodorizing filter (32) are disposed so that their respective filter surfaces are substantially horizontal at a height position substantially at the center of the casing (10).

[0047] The deodorizing filter (32) is disposed above the dust collecting filter (31). In the air purification unit (U2), fine pollen, PM2.5, and other dust particles are first removed by the dust collecting filter (31). The air that has passed through the dust collecting filter (31) has formaldehyde, odorous components, and the like adsorbed or decomposed by the deodorizing filter (32) that contains activated carbon or the like. In this manner, the air is purified by passing through the air purification unit (U2).

[0048] (5) Humidification unit The humidification unit (U3) is disposed in the humidification chamber (4). The humidification unit (U3) humidifies the air in the air passage (AP). The humidification unit (U3) is an example of a humidification section (U3) of the present disclosure. The humidification unit (U3) includes an evaporation filter (41) and a frame (42).

[0049] The evaporation filter (41) has a disk-shaped evaporation material. The evaporation material is, for example, a nonwoven fabric. Water adheres to the evaporation material, thereby supplying moisture to air passing through the evaporation filter (41). The evaporation filter (41) is arranged with its filter surface facing in the left-right direction.

[0050] The frame (42) is made of a resin material and has an annular shape. The evaporation filter (41) is held on the inner rim of the frame (42). A first shaft portion (43) is provided at the center of the circle of the frame (42). The first shaft portion (43) is connected to a motor (44) (see FIG. 4). When the motor (44) is driven, the frame (42) and the evaporation filter (41) rotate together. The frame (42) is positioned so that its lowest point is immersed in water in a second tray (50b) described below.

[0051] A plurality of water pumping portions (42a) are provided around the outer periphery of the frame (42). The plurality of water pumping portions (42a) are arranged at equal intervals. As the frame (42) rotates, the water pumping portions (42a) passing through the lowest point of the frame (42) pump up water. In this manner, the plurality of water pumping portions (42a) successively pump up the water in the tray (50).

[0052] When the water scooping parts (42a) pass near the top of the frame (42), they discharge water toward the evaporation filter (41). Water supplied from the water scooping parts (42a) adheres to the evaporation filter (41). In this manner, the evaporation filter (41) is configured to receive water as it rotates. Because the evaporation filter (41) rotates together with the frame (42), water is supplied evenly to the evaporation filter (41) from the multiple water scooping parts (42a). When air passes through the area of ​​the evaporation filter (41) where water adheres, moisture is supplied to the air (humidification).

[0053] (6) Water supply unit The water supply unit (U4) is disposed in the humidification chamber (4). The water supply unit (U4) supplies water to the humidification unit (U3). The water supply unit (U4) is disposed between the humidification unit (U3) and the side door (18). The water supply unit (U4) has a tray (50) and a tank (60).

[0054] (6-1) Tray As shown in FIGS. 1 and 4, the tray (50) is disposed in the humidification chamber (4). The tray (50) is disposed between the humidification unit (U3) and the side door (18). The tray (50) stores water supplied from the tank (60). The tray (50) supplies water to the humidification unit (U3). The tray (50) has a first tray (50a) and a second tray (50b). The tray (50) is configured to allow water to flow between the first tray (50a) and the second tray (50b).

[0055] (6-1-1) First Tray The first tray (50a) is disposed below the tank (60). Water stored in the tank (60) flows into the first tray (50a). A part of the bottom surface of the first tray (50a) is formed deep so that a float part (51) described below can be disposed therein. The first tray (50a) is provided with an antibacterial part (not shown). The antibacterial part has an antibacterial material and inhibits the growth of mold and bacteria in the water in the tray (50).

[0056] (6-1-2) Second Tray The second tray (50b) is disposed below the frame (42). The second tray (50b) is provided to cover the lower part of the frame (42) so that the water scooping part (42a) can scoop water. Specifically, the second tray (50b) has a plate-shaped bottom (58) and two side walls (59). The bottom (58) is formed in a plate shape with a curved plate surface that fits along the outer periphery of the frame (42). Each side wall (59) is formed in a substantially semicircular shape. The two side walls (59) are connected to the bottom (58) so as to face each other.

[0057] The second tray (50b) is provided with a bearing portion (59a) for rotatably supporting the first shaft portion (43) of the frame (42). The bearing portion (59a) is provided so as to extend upward from the center of the side wall (59).

[0058] (6-2) Float and water level sensor As shown in Fig. 5, the humidifier (1) of this embodiment includes a float (51) and a water level sensor (57). The float (51) opens and closes a water supply valve (66) provided on the bottom of the tank (60), which will be described later. The water level sensor (57) detects the height of the water surface in the tray (50).

[0059] The float portion (51) has a float body (52), a floater (53), a magnet (56), and a contact portion (54). The float body (52) is provided so as to extend from the right side surface of the first tray (50a) toward the center. The floater (53) is disposed near one end of the float body (52). The floater (53) is formed hollow so as to float on the water surface, and moves up and down depending on the height of the water surface. The magnet (56) is disposed at one end of the float body (52) so as to face the inner surface of the tank (60). The magnet (56) moves up and down integrally with the float body (52). The contact portion (54) is provided at the other end of the float body (52). The contact portion (54) is disposed directly below a water supply valve (66) described below.

[0060] A second shaft portion (55) is provided on a side surface of the float body (52). The second shaft portion (55) is supported by the first tray (50a). The second shaft portion (55) is disposed between the floater (53) and the contact portion (54) and at a position closer to the contact portion (54). Due to the seesaw principle, when the floater (53) at one end of the float body (52) rises, the contact portion (54) at the other end descends.

[0061] The water level sensor (57) detects the height position of the floater (53). The water level sensor (57) is, for example, a proximity sensor. The water level sensor (57) detects the height position of the floater (53) (the water level in the tray (50)) when the magnet (56) approaches the water level sensor (57) to a predetermined distance.

[0062] Specifically, when water is supplied from the tray (50) to the humidification unit (U3), the water level in the first tray (50a) (tray (50)) drops. This causes the magnet (56) to drop together with the floater (53), and when they reach a predetermined height, the water level sensor (57) detects that the magnet (56) is outside the predetermined distance. On the other hand, when water is supplied from the tank (60) to the tray (50), the water level in the first tray (50a) (tray (50)) rises. This causes the magnet (56) to rise together with the floater (53), and when they reach a predetermined height, the water level sensor (57) continues to detect that the magnet (56) is within the predetermined distance.

[0063] In this manner, the water level sensor (57) transmits an ON signal when the magnet (56) is within a detectable distance, and an OFF signal when the magnet is not within a detectable distance, to the control unit (C) described below as a signal indicating the water level information in the tray (50). Upon receiving the OFF signal, the control unit (C) displays on the display of the operation panel (16) that the amount of water stored in the tray (50) is relatively low.

[0064] (6-3) Tank The tank (60) supplies water to the tray (50). The tank (60) is rotatably supported by the casing (10). Specifically, as shown in FIGS. 4 to 6, the tank (60) is disposed inside the side door (18). The tank (60) rotates when the side door (18) is opened or closed. In other words, the first direction is also the direction in which the tank (60) rotates from the second position to the first position, and the second direction is also the direction in which the tank (60) rotates from the first position to the second position. The tank (60) is configured to be detachable from the casing (10). The tank (60) includes a tank body (61), a water supply valve (66), a water supply port (67), and a lid member (68).

[0065] (6-3-1) Tank body The tank body (61) is formed in a box shape. The width (front-rear) length of the tank body (61) is approximately the same as the width (front-rear) length of the side door (18). The depth (left-right) length of the tank body (61) is slightly shorter than the depth of the first tray (50a). The tank (60) has a removable top lid (63). With the top lid (63) removed, the tank body (61) opens upward.

[0066] The tank (60) is disposed so that the first side surface (61a) of the tank (60) is aligned along the inner surface of the side door (18). Specifically, the first side surface (61a) of the tank body (61) is disposed so as to face the inner surface of the side door (18).

[0067] A circular communication hole (64) is formed near the center of the bottom surface of the tank body (61). The communication hole (64) connects the tank (60) and the tray (50). Water in the tank (60) flows into the tray (50) through the communication hole (64). A cylinder portion (65) extending downward toward the first tray (50a) is connected to the communication hole (64). The bottom surface of the tank body (61) is inclined so that water flows toward the communication hole (64). A water supply valve (66) is provided in the communication hole (64). The water supply valve (66) opens and closes the communication hole (64).

[0068] (6-3-2) Water supply valve The water supply valve (66) is an example of the opening / closing mechanism (66) of the present disclosure. The water supply valve (66) is in communication with the tray (50). The water supply valve (66) includes a valve body (66a), a valve stem (66b), a disk portion (66c), and a first spring member (66d).

[0069] The valve body (66a) is provided so as to close the opening of the communication hole (64). Specifically, the valve body (66a) is formed in a conical shape that bulges downward. The conical surface of the valve body (66a) comes into contact with the edge of the opening of the communication hole (64), thereby closing the communication hole (64).

[0070] The valve shaft (66b) extends downward from the lower end of the valve body (66a). The valve shaft (66b) is disposed within the cylindrical portion (65). The valve shaft (66b) is movable up and down within the cylindrical portion (65). The disk portion (66c) is provided at the lower end of the valve shaft (66b).

[0071] The disk portion (66c) has a larger diameter than the valve stem (66b). The disk portion (66c) is disposed directly above the contact portion (54) of the float portion (51). The disk portion (66c) comes into contact with the contact portion (54) depending on the water level of the first tray (50a).

[0072] The first spring member (66d) is disposed around the valve shaft (66b). In other words, the valve shaft (66b) is inserted through the first spring member (66d). The first spring member (66d) biases the water supply valve (66) toward the first tray (50a). Specifically, the first spring member (66d) is fixed to the lower end of the cylindrical portion (65), and the lower end of the first spring member (66d) presses the disc portion (66c) downward.

[0073] When the contact portion (54) of the float (51) is not in contact with the disc portion (66c), the water supply valve (66) closes the communication hole (64), so that water in the tank (60) (inside the tank body (61)) is prevented from flowing out through the communication hole (64). On the other hand, when the contact portion (54) of the float (51) pushes up the disc portion (66c) (the state shown in FIG. 5), the water supply valve (66) rises, causing water in the tank (60) (inside the tank body (61)) to flow out through the communication hole (64) toward the tray (50). In this way, water is supplied to the tray (50) when the water supply valve (66) is open, and water is not supplied to the tray (50) when the water supply valve (66) is closed.

[0074] (6-3-3) Water supply port The water supply port (67) is provided in the tank (60). The water supply port (67) communicates with the tank (60) and supplies water from the outside into the tank (60). Specifically, the water supply port (67) is formed in the top lid (63) and communicates between the outside and the inside of the tank body (61). The opening of the water supply port (67) is formed across the width (front-rear) of the top lid (63).

[0075] Because the tank (60) is fixed to the inside of the side door (18), the water supply port (67) is disposed on the inside of the side door (18). Therefore, when the side door (18) is in the first position, the water supply port (67) is exposed to the outside of the casing (10). When the side door (18) is in the second position, the water supply port (67) is accommodated inside the casing (10). In this manner, by rotating the tank (60), the water supply port (67) is in the first position when supplying water and in the second position when not supplying water.

[0076] The water supply port (67) has an inlet (67a) and an outlet (67b). The inlet (67a) is formed at the upper end of the water supply port (67). Water from the outside flows in through the inlet (67a). The outlet (67b) is formed at the lower end of the water supply port (67). The water that flows in through the inlet (67a) flows out through the outlet (67b) into the tank (60). Both the inlet (67a) and the outlet (67b) are formed in a rectangular shape across the width direction (front-rear direction) of the top cover (63). The water supply port (67) has an inclined surface (69) that is inclined such that the opening area decreases from the inlet (67a) toward the outlet (67b). In this way, the opening area of ​​the outlet (67b) is smaller than the opening area of ​​the inlet (67a).

[0077] (6-3-4) Lid The lid member (68) is disposed on the water supply port (67) of the top lid (63). The lid member (68) is configured to be able to open and close the water supply port (67). Specifically, the lid member (68) is formed in a rectangular plate shape and disposed so as to cover the inlet (67a) of the water supply port (67). When viewed from the right, the lid member (68) is supported so as to be pivotable at the long side on the far side and configured so as to open from the front side. The lid member (68) is provided with a second spring member (76) that biases the lid member (68) in the opening direction.

[0078] (7) Overflow control mechanism The humidifier (1) of this embodiment has an overflow suppression mechanism (K). The overflow suppression mechanism (K) guides water overflowing from the water supply port (67) to the tray (50). Specifically, the overflow suppression mechanism (K) has a passage portion (P) and a pair of guard portions (19, 19). The passage portion (P) is a gap formed between the inner surface of the side door (18) and the first side surface (61a) of the tank body (61) (see FIG. 4). The upper end of the passage portion (P) is open, and the lower end thereof communicates with the first tray (50a). Thus, water overflowing from the water supply port (67) flows through the passage portion (P) and into the first tray (50a).

[0079] The guard portion (19) is a plate-shaped member. The guard portion (19) is provided on the inner surface of the side door (18). The pair of guard portions (19, 19) are provided along the passage portion (P) so as to cover both ends of the first side surface (61a). Specifically, the pair of guard portions (19) are provided on both ends of the width direction (front-rear direction) of the inner surface of the side door (18) so as to extend in the up-down direction. The gap between the guard portion (19) and the side surface of the tank body (61) communicates with the first tray (50a). Thus, water overflowing from the water supply port (67) flows inside the guard portion (19) and into the first tray (50a). The guard portion (19) is an example of a wall portion (19) in the present disclosure.

[0080] (8) Stopper As shown in Fig. 7, the humidifier (1) of this embodiment includes a stopper (70). The stopper (70) is an example of the restricting member (70) of the present disclosure.

[0081] The stopper (70) is a plate-shaped member. The stopper (70) is rotatably supported inside the front panel (13a) by a third shaft portion (73) provided at the upper portion (see FIG. 1). The stopper (70) is biased by a spring member (not shown) so as to rotate counterclockwise (in the direction of the arrow in FIG. 7) when viewed from the front. A first engagement recess (71) and a second engagement recess (72) are formed vertically side by side on the right edge of the stopper (70). The first engagement recess (71) and the second engagement recess (72) are fitted into an engagement protrusion (75) protruding forward from the guard portion (19).

[0082] In the second position, the first engagement recess (71) is engaged with the engagement protrusion (75) ( FIG. 7( a )). As the side door (18) opens (tilts in the first direction), the engagement protrusion (75) moves from the first engagement recess (71) to the second engagement recess (72) while sliding along the right edge of the stopper (70). In the first position, the second engagement recess (72) is engaged with the engagement protrusion (75) ( FIG. 7( b )). In this way, the stopper (70) prevents the tank (60) from tilting further in the first direction from the first position.

[0083] (9) Control unit As shown in Fig. 8, the humidifier (1) has a control unit (C). The control unit (C) controls the operation of the humidifier (1). The control unit (C) is provided with a microcomputer and a memory device that stores software for operating the microcomputer.

[0084] The control unit (C) is connected to various devices of the humidifier (1) by wire or wirelessly. For example, the control unit (C) is connected to the water level sensor (57), the fan motor (22), the motor (44), and the operation panel (16). Based on predetermined operation commands transmitted from the operation panel (16) (e.g., commands to start / stop the humidifier (1), to start / stop the humidifying operation, and to start / stop the drying operation), the control unit (C) controls the operations of the various devices.

[0085] (10) Operating the humidifier Next, various operations of the humidifier (1) of this embodiment will be described.

[0086] (10-1) Humidification operation The humidification operation is an operation in which the sucked indoor air is purified and humidified, and then blown out again into the indoor space. When the humidification operation is selected on the operation panel (16), the control unit (C) drives the fan motor (22) and the motor (44). The control unit (C) controls the rotation speed of the fan (21) and the evaporation filter (41) based on the set amount of humidification and air volume.

[0087] By the rotation of the fan (21), indoor air sucked in through the suction port (15) is transported from the ventilation chamber (2) to the air purification chamber (3). The air transported to the air purification chamber (3) is purified by passing through the air purification unit (U2). The air that has passed through the air purification unit (U2) is transported to the humidification chamber (4).

[0088] The air that has flowed into the humidification chamber (4) passes through the rotating evaporation filter (41). Since moisture is attached to the evaporation filter (41) as a result of water being supplied from the water pumping section (42a), moisture is supplied to the air passing through the evaporation filter (41).

[0089] Moisture is removed from the evaporation filter (41) by the air passing through, but because the evaporation filter (41) is rotating, the water pumping parts (42a) sequentially pump up water from the second tray (50b) and supply the water to the evaporation filter (41) one after another. Therefore, during the humidification operation, the evaporation filter (41) always contains moisture and continues to supply moisture to the air passing through the evaporation filter (41).

[0090] The air humidified in the humidification chamber (4) is blown out into the room through the air outlet (14). When the humidity in the room reaches the target humidity, the control unit (C) stops the humidification operation. This stops the humidification operation. In this example, during the humidification operation, the air purification operation described below is also performed at the same time.

[0091] (10-2) Air purifying operation The air purification operation is an operation for purifying the sucked indoor air. When the air purification operation is selected on the operation panel (16), the control unit (C) drives the fan motor (22). Driving the fan motor (22) generates an air flow in the air passage (AP) in which the indoor air sucked through the suction port (15) flows toward the air outlet (14). The control unit (C) controls the rotation speed of the fan (21) based on the set air volume.

[0092] By the rotation of the fan (21), room air is sucked in through the suction port (15) and transported from the ventilation chamber (2) to the air purification chamber (3). The air transported to the air purification chamber (3) passes through a dust collection filter (31) and a deodorization filter (32). The air thus purified is transported to the humidification chamber (4).

[0093] The air that flows into the humidification chamber (4) passes through the evaporative filter (41). When the humidification operation is not performed, the evaporative filter (41) is stopped, and therefore moisture is not supplied to the air passing through the evaporative filter (41). The air that has passed through the evaporative filter (41) is blown into the room. When a command to stop the operation of the humidifier (1) is sent from the operation panel (16) or a predetermined time has elapsed by a timer function or the like, the control unit (C) stops the air purification operation.

[0094] (10-3) Drying operation The drying operation is an operation in which, after the operation of the humidifier (1) is stopped, the evaporation filter (41) is dried by blowing air from the fan (21). The drying operation can dry the evaporation filter (41) in a shorter time than natural drying, and therefore can prevent mold and odors from growing on the evaporation filter (41).

[0095] The drying operation function can be switched on / off in the local settings based on the user's operation. In this example, the drying operation function is turned on by pressing multiple buttons on the operation panel (16) in a predetermined sequence.

[0096] When the drying operation function is turned on, the control unit (C) drives the fan motor (22) to perform the drying operation after stopping the operation of the humidifier (1). In the drying operation, the control unit (C) controls the rotation speed of the fan (21) so as to obtain a minimum air volume.

[0097] By the rotation of the fan (21), room air is sucked in through the suction port (15) and transported from the ventilation chamber (2) to the air cleaning chamber (3) and then to the humidification chamber (4). The air that flows into the humidification chamber (4) passes through the evaporation filter (41), which is not operating. This air dries the evaporation filter (41). The air that has passed through the evaporation filter (41) is blown out into the room. After a predetermined time has elapsed, the control unit (C) stops the drying operation.

[0098] (11) Supplying water to the humidifier Next, a method for supplying water to the humidifier (1) of this embodiment will be described. There are a first water supply method and a second water supply method as the method for supplying water to the humidifier (1). In the first water supply method, water is supplied into the tank (60) while the tank (60) remains attached to the casing (10). In the second water supply method, water is supplied into the tank (60) after removing the tank (60) from the casing (10).

[0099] (11-1) 1st water supply method 3 and 7, when the handle (18a) of the side door (18) in the second position is pulled toward the user, the side door (18) tilts toward the user so that the upper end is gradually opened. As the side door (18) tilts toward the first direction, the tank (60) also gradually tilts toward the first direction.

[0100] As the side door (18) tilts, the cover member (68) gradually opens from the front side. When the second engaging recess (72) of the stopper (70) fits into the engaging protrusion (75), the side door (18) is restricted from further rotating in the first direction and assumes the first position. In this first position, the cover member (68) is completely open, and the water supply port (67) changes from a closed state to an open state. In this way, the cover member (68) changes so that the water supply port (67) is in a closed state in the second position and the water supply port (67) is in an open state in the first position.

[0101] In this first position, when water is poured into the water inlet from a container (such as a kettle) containing water, the tank (60) becomes heavier and attempts to rotate in the second direction due to its own weight. However, the cover member (68) is biased to keep the water inlet (67) open by pressing the upper surface of the cover member (68) against the right side panel (13c), so that the tank (60) is restricted from changing from the first position to the second position. This prevents the side door (18) from closing by itself while water is being supplied to the tank (60). Water that spills in front of or to the side of the water inlet (67) or overflows from the water inlet while water is being supplied flows into the first tray (50a) through the passage portion (P) and the inside of the guard portion (19).

[0102] When a predetermined amount of water is stored in the tank (60), water supply is completed. Thereafter, when the side door (18) is pushed in the second direction, the engaging protrusion (75) disengages from the second engaging recess (72) of the stopper (70), and the side door (18) changes from the first position to the second position. The side door (18) moves in the second direction while the top surface of the cover member (68) presses against the right side panel (13c), so that the side door (18) does not close suddenly. This prevents fingers from getting pinched.

[0103] When the side door (18) is closed and in the second position, the engaging projection (75) fits into the first engaging recess (71) of the stopper (70). In this state, water is supplied from the tank (60) to the tray (50). Specifically, when the water level in the first tray (50a) is lower than a predetermined water level, the contact portion (54) of the float portion (51) pushes up the disk portion (66c) of the water supply valve (66). This opens the water supply valve (66), and the water in the tank (60) flows into the first tray (50a) through the communication hole (64) of the tank (60) (tank body (61)). This causes the water level in the first tray (50a) to rise, and the floater (53) to rise. As the floater (53) rises, the contact portion (54) descends. When the water level in the first tray (50a) reaches a predetermined level, the contact portion (54) moves away from the disk portion (66c). When the contact portion (54) moves completely away from the disk portion (66c), the water supply valve (66) closes, and the supply of water from the tank (60) to the tray (50) stops.

[0104] (11-2)Second water supply method As in the first water supply method, the side door (18) is changed from the second position to the first position. When the stopper (70) is pushed downward in the first position, the second engagement recess (72) is disengaged from the engagement protrusion (75). This allows the tank (60) to be removed from the casing (10) together with the side door (18). The tank (60) is carried to a place where water can be supplied, such as a kitchen or a washroom, and the top lid (63) is removed from the tank body (61) to supply water directly to the tank body (61) from a faucet. In this case, since the top lid (63) is removed, a predetermined amount of water can be stored in the tank body (61) in a shorter time than when water is supplied from the water supply port (67). Since the water supply valve (66) closes the communication hole (64) by the first spring member (66d), leakage of water from the tank (60) during water supply is suppressed.

[0105] The top lid (63) is attached to the tank body (61) again, and the tank (60) is moved to the humidifier (1) again. The stopper (70) is rotated toward the front by bringing the engaging protrusion (75) into contact with the stopper (70) and pushing it downward, thereby attaching the tank (60) and the side door (18) to the casing (10). With the right edge (74) of the stopper (70) in contact with the engaging protrusion (75), the side door (18) is pushed in the second direction, so that the side door (18) assumes the second position. In the second position, the engaging protrusion (75) fits into the first engaging recess (71) of the stopper (70). Thereafter, water is supplied from the tank (60) to the tray (50) in the same manner as in the first water supply method.

[0106] (12) Features (12-1) The humidifier (1) of this embodiment includes a tray (50) that supplies water to the humidification unit (U3), a tank (60) that supplies water to the tray (50), and a water supply port (67) that communicates with the tank (60) and supplies water from the outside into the tank (60). The water supply port (67) is disposed so as to be exposed to the outside of the casing (10).

[0107] In the case of a conventional humidifier that supplies water directly to the tank from a faucet, removing the tank from the humidifier body and then reattaching the tank filled with water to the humidifier body requires multiple steps, such as opening and closing the cap on the water inlet and going back and forth between the installation location of the humidifier and the installation location of the faucet, which can be inconvenient for some users. In view of this, the humidifier (1) of the present embodiment has a water inlet (67) exposed to the outside of the casing (10), so that water can be directly supplied to the tank (60) from the outside via the water inlet (67).

[0108] (12-2) The water inlet (67) of the humidifier (1) of this embodiment changes between a first position in which it is exposed to the outside of the casing (10) when supplying water and a second position in which it is housed inside the casing (10) when not supplying water. In this way, water can be supplied into the tank (60) by putting the water inlet (67) into the first position depending on the timing of water supply. When water is not being supplied, the water inlet (67) is put into the second position, so that the water inlet (67) is housed inside the casing (10) and dust and the like can be prevented from entering the water inlet (67).

[0109] (12-3) The humidifier (1) of the present embodiment further includes an openable and closable side door (18) constituting a part of the side surface of the casing (10). The water inlet (67) is disposed inside the side door (18), and the first position is a state in which the side door (18) is open, and the second position is a state in which the side door (18) is closed. Thus, by opening and closing the side door (18), the water inlet (67) can be changed between the first position and the second position. When pouring water into the water inlet using a container such as a kettle, since the side door (18) is located on the side surface of the casing (10), it is not necessary to lift the kettle, which makes the water supplying operation easier, as compared to, for example, supplying water from the top surface of the casing (10).

[0110] (12-4) The humidifier (1) of the present embodiment further includes an openable and closable lid member (68) disposed on the water inlet (67). By opening and closing the lid member (68) so that the water inlet (67) is exposed to the outside only when water is being supplied, it is possible to prevent water from splashing to the outside from the water inlet (67) when the lid member (68) is closed.

[0111] (12-5) The cover member (68) of the humidifier (1) of this embodiment changes so that the water inlet (67) is open in the first position and the water inlet (67) is closed in the second position. When the flap (17) is open in the second position, dust and other particles in the air enter the inside of the casing (10) through the air outlet (14). However, in the second position, the cover member (68) closes the water inlet (67), which prevents dust from entering the water inlet (67).

[0112] (12-6) In the first position, the cover member (68) of the humidifier (1) of this embodiment is biased to keep the water supply port (67) open, and is prevented from changing from the first position to the second position. This allows water to be supplied to the tank (60) without the need to open the cover member (68). In addition, because the cover member (68) is prevented from changing from the first position to the second position, it is possible to prevent the cover member (68) from changing to the second position while supplying water from the first position.

[0113] (12-7) The water supply inlet (67) of the humidifier (1) of this embodiment is provided in the tank (60). The tank (60) is rotatably supported by the casing (10), and the water supply inlet (67) changes between a first position and a second position as the tank (60) rotates. In this way, the water supply inlet (67) can be easily changed between a closed state and an open state by simply rotating the tank (60).

[0114] (12-8) The humidifier (1) of the present embodiment further includes a stopper (70) that prevents the tank (60) from tilting further in the first direction from the first position. The stopper (70) prevents the tank (60) from tilting further toward the front from the first position. As a result, water in the tank (60) is prevented from spilling out of the water inlet (67) and the tank (60) is prevented from coming off the casing (10) together with the side door (18).

[0115] (12-9) The humidifier (1) of the present embodiment further includes an overflow suppression mechanism (K) that guides water overflowing from the water supply port (67) to the tray (50). For example, even if water overflows from the water supply port (67) during water supply, the overflow suppression mechanism (K) guides the water to the tray (50), thereby preventing the water from entering the devices inside the casing (10). This makes it possible to prevent breakdowns in the humidifier (1).

[0116] (12-10) The overflow suppression mechanism (K) of the humidifier (1) of this embodiment includes a passage portion (P) formed between the inner surface of the side door (18) and the first side surface (61a), and a pair of guard portions (19) provided on the side door (18) along the passage portion (P) so as to cover both ends of the first side surface (61a). Water spilled between the side door (18) and the first side surface (61a) of the tank (60) can flow into the tray (50) through the passage portion (P). Water spilled on both sides of the first side surface can flow into the tray (50) through the inner surfaces of the guard portions (19).

[0117] (12-11) The tank (60) of the humidifier (1) of this embodiment is configured to be detachable from the casing (10). Water can also be supplied by removing the tank (60). This allows two water supply methods to be realized: a method of directly supplying water to the tank, and a method of supplying water by removing the tank (60).

[0118] (12-12) The tank (60) of the humidifier (1) of this embodiment includes a water supply valve (66) that communicates with the tray (50). When the water supply valve (66) is open, water is supplied to the tray (50), and when the water supply valve (66) is closed, water is not supplied. The water supply valve (66) of this embodiment is opened and closed by a contact portion (54) of a float portion (51) that moves up and down depending on the water level in the tray (50). In this way, when the water level in the tray (50) becomes relatively low, the water supply valve (66) opens, and water is supplied from the tank (60) to the tray (50). When the water level in the tray (50) reaches the full water level, the water supply valve (66) closes, thereby preventing water from overflowing from the tray (50).

[0119] (12-13) The water supply port (67) of the humidifier (1) of this embodiment includes an inlet (67a) through which water flows in and an outlet (67b) through which the water flowing in from the inlet (67a) flows out into the tank (60), and the opening area of ​​the outlet (67b) is smaller than the opening area of ​​the inlet (67a). By making the outlet (67b) smaller than the inlet (67a) in this manner, it is possible to prevent the water flowing into the tank (60) from splashing out of the water supply port (67).

[0120] (13) Other embodiments The above embodiment may be configured as follows.

[0121] The water supply inlet (67) of the humidifier (1) may be separate from the tank (60). The water supply inlet (67) only needs to communicate between the outside and the inside of the tank (60), and may be connected to the tank (60) via a member such as a tube. In this case, water poured into the water supply inlet (67) flows into the tank (60) through the tube.

[0122] The tank (60) of the humidifier (1) may be non-detachable from the casing (10) (fixed to the casing (10)).

[0123] The side door (18) of the humidifier (1) may be a door that opens to the side. For example, the side door (18) may be rotated so that the left end or the right end is opened. The humidifier (1) may have a so-called drawer structure in which the side door (18) and the tank (60) are pulled out from the casing (10) to the outside, thereby exposing the water inlet (67) to the outside. The air purification unit (U2) and the humidification unit (U3) of this embodiment may have the same configuration as the air purification unit and the humidification element described in Patent Document 1 (for example, FIG. 3), respectively.

[0124] The stopper (70) of the humidifier (1) may have a damper structure to prevent the side door (18) from suddenly closing when the side door (18) changes from the first position to the second position. For example, the damper structure may be a gear damper. The gear damper has a gear formed along the left edge of the stopper (70). The gear meshes with an engagement portion (not shown) fixed to the inside of the front panel (13a), thereby preventing the side door (18) from suddenly changing from the first position to the second position. This makes it possible to prevent the side door (18) from closing unexpectedly due to the weight of water in the tank (60) during water supply, and thus to prevent fingers from being pinched between the side door (18) and the right side panel (13c). In addition, the stopper (70) having such a damper structure does not require the lid member (68) for maintaining the first position as in the above embodiment.

[0125] The overflow suppression mechanism (K) of the embodiment need only be configured to guide water overflowing from the water supply port (67) to the tray (50), and may not include the guard portion (19).

[0126] Although the embodiments and modifications have been described above, it will be understood that various modifications of form and details are possible without departing from the spirit and scope of the claims. Furthermore, the above embodiments and modifications may be appropriately combined or substituted as long as the functions of the subject matter of this disclosure are not impaired. The descriptions "first", "second", ... described above are used to distinguish the words to which these descriptions are attached, and do not limit the number or order of the words.
