[0003] Patent Document 1: Japanese Laid-Open Patent Publication No. 2016-3842 SUMMARY

[0004] PROBLEMS TO BE SOLVED BY THE INVENTION

[0005] With the humidifier of Patent Document 1, the user detaches the water tank from the humidifier main body and supplies water to the water tank in a kitchen or a bathroom where there is a faucet. As such, although it is possible to directly supply water to the water tank from the faucet, the water tank needs to be detached from the humidifier main body and attached again to the humidifier main body after being supplied with water, and thus the existing method has a problem in that the operation of the user to supply water to the water tank is very laborious.

[0006] An object of the present disclosure is to provide a humidifying device that can easily supply water to a water tank.

[0007] SOLUTION TO THE PROBLEMS

[0008] The disclosure of the first aspect is a humidifying device including a housing 10, an air passage AP formed in the housing 10, a humidifying portion U3 that humidifies air flowing in the air passage AP, a tray 50 that supplies water to the humidifying portion U3, a water tank 60 that supplies water to the tray 50, and a water supply port 67 that communicates with the water tank 60 and supplies water to the inside of the water tank 60 from the outside, the water supply port 67 being arranged in a manner that can be exposed to the outside of the housing 10.

[0009] In the first aspect, by exposing the water supply port 67 to the outside of the housing 10, it is possible to directly supply water to the water tank 60 from the water supply port 67 without detaching the water tank 60 from the humidifying device main body.

[0010] The disclosure of the second aspect is based on the disclosure of the first aspect,

[0011] The water supply port 67 changes between a first posture in which it is exposed to the outside of the housing 10 at the time of water supply and a second posture in which it is housed inside the housing 10 at the time of non-water supply.

[0012] In the second aspect, water can be supplied into the water tank 60 by changing the water supply port 67 to the first posture depending on the timing of water supply. Since the water supply port 67 is not exposed to the outside of the housing 10 in the second posture, entry of dust and the like into the water tank 60 via the water supply port 67 can be suppressed.

[0013] The third aspect is disclosed on the basis of the disclosure of the second aspect,

[0014] The humidifying device further includes a door portion 18 that constitutes a part of the side surface of the housing 10 and that is openable and closable, and the water supply port 67 is arranged on the inner side of the door portion 18, the first posture is a state in which the door portion 18 is open, and the second posture is a state in which the door portion 18 is closed.

[0015] In the third aspect, the water supply port 67 is changed between the first posture and the second posture by opening and closing the door portion 18. When water is supplied to the water supply port using a container such as a water pitcher, since the door portion 18 is located on the side surface of the housing 10, the water supply work is easy, for example, compared to the case of water supply from the top surface of the housing 10, without lifting the water pitcher.

[0016] The fourth aspect is disclosed on the basis of the disclosure of the third aspect, and the humidifying device further includes a cover member 68 that is arranged at the water supply port 67 and that is openable and closable.

[0017] In the fourth aspect, the cover member 68 is opened and closed to expose the water supply port 67 to the outside only at the time of water supply, whereby in the state in which the cover member 68 is closed, water can be suppressed from flying out to the outside from the water supply port 67.

[0018] The fifth aspect is disclosed on the basis of the disclosure of the fourth aspect,

[0019] The cover member 68 changes in such a manner that the water supply port 67 is in an open state in the first posture and that the water supply port 67 is in a closed state in the second posture.

[0020] In the fifth aspect, entry of dust into the water supply port 67 can be suppressed in the second posture.

[0021] The sixth aspect is disclosed on the basis of the disclosure of the fifth aspect,

[0022] In the first posture, the cover member 68 is energized to maintain the open state of the water supply port 67, and change from the first posture to the second posture is limited.

[0023] In the sixth aspect, water supply is possible without intentionally opening the lid member 68 by hand. In addition, since the change from the first posture to the second posture is limited, it is possible to suppress the change to the second posture during water supply in the first posture.

[0024] The seventh aspect is disclosed on the basis of any one of the third to sixth aspects,

[0025] The water supply port 67 is provided on the water tank 60 that is supported by the housing 10 and is swingable, and changes between the first posture and the second posture in accordance with the swing of the water tank 60.

[0026] In the seventh aspect, the water supply port 67 changes between the first posture and the second posture by swinging the water tank 60 alone.

[0027] The eighth aspect is disclosed on the basis of the seventh aspect,

[0028] The humidifying device further includes a limiting member 70 that limits the water tank 60 from further tilting to the first direction side from the first posture when the direction in which the water tank 60 is swung from the second posture to the first posture is set as the first direction and the direction in which the water tank 60 is swung from the first posture to the second posture is set as the second direction.

[0029] In the eighth aspect, the water tank 60 is limited from further tilting to the first direction from the first posture by the limiting member 70. Thus, it is possible to suppress the water in the water tank 60 from overflowing from the water supply port 67.

[0030] The ninth aspect is disclosed on the basis of the seventh or eighth aspect,

[0031] The humidifying device further includes an overflow suppression mechanism K that guides the water overflowing from the water supply port 67 to the tray 50.

[0032] In the ninth aspect, even if the water overflows from the water supply port 67 during water supply, the water is guided into the tray 50, and thus it is possible to suppress the water from entering the mechanical parts inside the housing 10, which results in the possibility of suppressing the malfunction of the humidifying device.

[0033] The tenth aspect is disclosed on the basis of the ninth aspect,

[0034] The water tank 60 is arranged so that the first side surface 61a of the water tank 60 extends along the inner surface of the door portion 18, and the overflow suppression mechanism K includes a passage portion P and a pair of wall portions 19. The passage portion P is formed between the inner surface of the door portion 18 and the first side surface 61a, and the pair of wall portions 19 are provided on the door portion 18 along the passage portion P so as to cover both ends of the first side surface 61a.

[0035] In the tenth aspect, water overflowing between the door portion 18 and the first side surface 61a of the water tank 60 can flow into the tray 50 along the passage portion P. Water overflowing to both sides of the first side surface 61a can flow into the tray 50 along the inner surfaces of the wall portions 19.

[0036] The eleventh aspect is disclosed on the basis of the disclosure of any one of the first to tenth aspects,

[0037] The water tank 60 is configured to be detachable with respect to the housing 10.

[0038] In the eleventh aspect, the water tank 60 can be detached to supply water. Thus, water can be supplied by either of a method of directly supplying water to the water tank 60 and a method of supplying water by detaching the water tank 60, depending on the situation.

[0039] The twelfth aspect is disclosed on the basis of the disclosure of any one of the first to eleventh aspects,

[0040] The water tank 60 includes an opening and closing mechanism 66 that communicates with the tray 50, and water is supplied to the tray 50 when the opening and closing mechanism 66 is in an open state, and water is not supplied to the tray 50 when the opening and closing mechanism 66 is in a closed state.

[0041] In the twelfth aspect, for example, by bringing the opening and closing mechanism 66 into the closed state when the water tank 60 is in a full state, it is possible to avoid supplying water to the tray 50. Thus, it is possible to suppress water from overflowing from the tray 50.

[0042] The thirteenth aspect is disclosed on the basis of the disclosure of any one of the first to twelfth aspects,

[0043] The water supply port 67 includes an inflow port 67a through which water flows in and an outflow port 67b through which water flowing in from the inflow port 67a flows out into the water tank 60, and the opening area of the outflow port 67b is smaller than the opening area of the inflow port 67a.

[0044] In the thirteenth aspect, by making the outflow port 67b smaller than the inflow port 67a, it is possible to suppress water leakage from the water supply port 67 due to splashing and rebound of water flowing into the water tank 60. BRIEF DESCRIPTION OF DRAWINGS

Specifically, each suction port 15 is provided at a position lower than the center of each side face panel 13c, 13d and at substantially the entire region in the width direction (front-rear direction) of each side face panel 13c, 13d. At each suction port 15, a pre-filter (not shown) is arranged. The pre-filter is arranged so as to cover each suction port 15. In this way, relatively large dust and the like can be trapped. The bottom plate 12 closes the lower ends of the side plates 13.

[0062] (2-1-1) Side door

[0063] A side door 18 is provided on the housing 10. The side door 18 is an example of the door portion 18 of this disclosure. The side door 18 forms part of the side of the housing 10. Specifically, the side door 18 forms part of the right side panel 13c. The side door 18 is formed in a rectangular shape and forms part of approximately the entire area of ​​the right side panel 13c in the width direction (front-back direction) above the center of the right side panel 13c.

[0064] Side door 18 is configured to be able to open and close (see reference). Figure 3 Specifically, the lower end of the side door 18 is supported within the housing 10 and is capable of swinging. By pulling the handle 18a of the side door 18 towards the proximal side, the side door 18 tilts towards the proximal side, opening at the top. The side door 18 tilts 25 to 45 degrees from the fully closed state (the vertical state of the side door 18) when fully open.

[0065] In the following description, the state in which the side door 18 is open is referred to as the first posture ( Figure 3 (b) state), the state in which the side door 18 is closed is called the second posture ( Figure 3 (a) State). The open state refers to the state where the side door 18 is fully open, and the closed state refers to the state where the side door 18 is fully closed. The direction in which the side door 18 is swung from the second position to the first position in an inclined manner is called the first direction, and the direction in which the side door 18 is swung from the first position to the second position is called the second direction. Here, the state where the side door 18 is fully open means that the side door 18 is supported in the first position without swinging further in the first direction. It should be noted that the first position can also be the following state: In the first water supply method described later, at least a portion of the water inlet 67 is exposed to the outside of the housing 10 in a state where water can be supplied from the outside.

[0066] (3) Fan unit

[0067] Fan unit U1 is arranged inside air supply chamber 2. Fan unit U1 is positioned opposite to intake port 15. Fan unit U1 includes fan 21 and fan motor 22.

[0068] Fan 21 is a sirocco fan. Fan 21 is driven to rotate by fan motor 22. Fan 21 draws indoor air into the air supply chamber 2 through each intake port 15 and delivers it sequentially to the air purification chamber 3 and the humidification chamber 4 towards the outlet port 14. In this way, fan 21 delivers air from the intake port 15 to the outlet port 14 within the air passage AP.

[0069] The airflow of fan 21 is variable. Specifically, fan motor 22 is configured to have variable speed. The speed of fan motor 22 can be switched in multiple stages. The speed of fan motor 22 is controlled by control unit C.

[0070] (4) Air purification unit

[0071] The air purification unit U2 is arranged in the air purification chamber 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 arranged in a substantially horizontal manner at a substantially central height position of the housing 10 with respective filter faces.

[0072] The deodorizing filter 32 is arranged above the dust collecting filter 31. In this air purification unit U2, first, fine pollen, PM2.5, and the like dust and the like are removed by the dust collecting filter 31. The formaldehyde and the odor components and the like in the air after passing through the dust collecting filter 31 are adsorbed or decomposed by the deodorizing filter 32 containing activated carbon and the like. In this way, by making the air pass through the air purification unit U2, the air is purified.

[0073] (5) Humidification unit

[0074] The humidification unit U3 is arranged in the humidification chamber 4. The humidification unit U3 humidifies the air of the air passage AP. The humidification unit U3 is an example of the humidification section U3 of the present disclosure. The humidification unit U3 has a vaporizing filter 41 and a frame 42.

[0075] The vaporizing filter 41 has a circular plate-shaped vaporizing member. The vaporizing member is, for example, a nonwoven fabric. Water is attached to the vaporizing member, thereby supplying moisture to the air passing through the vaporizing filter 41. The vaporizing filter 41 is arranged with the filter face facing the left-right direction.

[0076] The frame 42 is composed of a circular ring-shaped resin member. On the inner rim of the frame 42, the vaporizing filter 41 is held. In the center of the circle of the frame 42, a first shaft section 43 is provided. The first shaft section 43 is connected to a motor 44 (refer to FIG. 2). By the operation of the motor 44, the frame 42 and the vaporizing filter 41 are integrally rotated. The frame 42 is arranged with its lowest point immersed in the water in the second tray 50b described later. Figure 4 ). By the operation of the motor 44, the frame 42 and the vaporizing filter 41 are integrally rotated. The frame 42 is arranged with its lowest point immersed in the water in the second tray 50b described later.

[0077] On the outer periphery of the frame 42, a plurality of water scooping sections 42a are arranged in the circumferential direction. The plurality of water scooping sections 42a are arranged at equal intervals. By the rotation of the frame 42, the water scooping sections 42a at the lowest point of the frame 42 scoop up the water. In this way, the plurality of water scooping sections 42a scoop up the water in the tray 50 in turn.

[0078] When the water intake section 42a passes near the highest point of the frame 42, the water in the water intake section 42a flows out to the vaporization filter 41. Water is supplied from the water intake section 42a, causing moisture to adhere to the vaporization filter 41. In this way, the vaporization filter 41 is configured to be supplied with water by rotation. Because the vaporization filter 41 rotates together with the frame 42, water is supplied evenly to the vaporization filter 41 from multiple water intake sections 42a. Moisture (humidification) is supplied to the air by passing it through the water-adhered area of ​​the vaporization filter 41.

[0079] (6) Water supply unit

[0080] Water supply unit U4 is located inside humidification chamber 4. Water supply unit U4 supplies water to humidification unit U3. Water supply unit U4 is located between humidification unit U3 and side door 18. Water supply unit U4 has tray 50 and water tank 60.

[0081] (6-1) Tray

[0082] like Figure 1 and Figure 4 As shown, tray 50 is arranged inside humidification chamber 4. Tray 50 is positioned between humidification unit U3 and side door 18. Tray 50 stores water supplied from water tank 60. Tray 50 supplies water to humidification unit U3. Tray 50 has a first tray 50a and a second tray 50b. Tray 50 is configured such that water from the first tray 50a and the second tray 50b can flow between them.

[0083] (6-1-1) First tray

[0084] The first tray 50a is positioned below the water tank 60. Water stored in the water tank 60 flows into the first tray 50a. A portion of the bottom surface of the first tray 50a is formed as a deep bottom to accommodate the floating part 51, which will be described later. An antibacterial part (not shown) is provided on the first tray 50a. The antibacterial part is made of antibacterial material to inhibit the growth of mold and bacteria in the water within the tray 50.

[0085] (6-1-2) Second tray

[0086] The second tray 50b is arranged below the frame 42. The second tray 50b is positioned to cover the lower part of the frame 42, allowing the water-drawing part 42a to dispense water. Specifically, the second tray 50b has a plate-shaped bottom 58 and two side walls 59. The bottom 58 is formed as a plate whose surface curves along the outer periphery of the frame 42. Each side wall 59 is formed as approximately semi-circular. The two side walls 59 are connected to the bottom 58 in a manner opposite to each other.

[0087] On the second tray 50b, there is a bearing portion 59a, which supports the first shaft portion 43 of the frame 42 and the first shaft portion 43 is rotatable. The bearing portion 59a is configured to extend upward from the center of the side wall 59.

[0088] (6-2) Float and water level sensor

[0089] As shown in FIG. 1, the humidifying device 1 of the present example has a float 51 and a water level sensor 57. The float 51 opens and closes a water supply valve 66 provided on a bottom surface of a water tank 60, which will be described later. The water level sensor 57 detects a height position of a water surface of the tray 50. Figure 5

[0090] The float 51 has a float main body 52, a float 53, a magnet 56, and a contact 54. The float main body 52 is provided to extend from a right side surface of the first tray 50a toward the center. The float 53 is arranged near one end of the float main body 52. The float 53 is formed to be hollow so as to float on the water surface and to move up and down in accordance with a change in the height of the water surface. The magnet 56 is arranged at the one end of the float main body 52 and opposes an inner side surface of the water tank 60. The magnet 56 moves up and down integrally with the float main body 52. The contact 54 is provided at the other end of the float main body 52. The contact 54 is arranged directly below the water supply valve 66, which will be described later.

[0091] A second shaft portion 55 is provided on a side surface of the float main body 52. The second shaft portion 55 is supported by the first tray 50a. The second shaft portion 55 is arranged between the float 53 and the contact 54 and near the contact 54. The float main body 52 moves according to a seesaw principle, for example, when the float 53 at the one end of the float main body 52 rises, the contact 54 at the other end falls.

[0092] The water level sensor 57 detects the height position of the float 53. The water level sensor 57 is, for example, a proximity sensor. The water level sensor 57 detects the height position of the float 53 (the water level of the tray 50) by the magnet 56 being close to the water level sensor 57 at a prescribed distance.

[0093] Specifically, when water is supplied from the tray 50 to the humidifying unit U3, the water level of the first tray 50a (the tray 50) falls. In this way, the magnet 56 also falls together with the float 53, and when it falls to a prescribed height position, the water level sensor 57 detects that the magnet 56 is outside the prescribed distance. On the other hand, when water is supplied from the water tank 60 to the tray 50, the water level of the first tray 50a (the tray 50) rises. In this way, the magnet 56 also rises together with the float 53, and when it rises to a prescribed height position, the water level sensor 57 detects that the magnet 56 is within the prescribed distance.

[0094] ​As such, when the magnet 56 is within the detectable distance, the water level sensor 57 sends a first signal to the control section C described later, and when the magnet is not within the detectable distance, the water level sensor 57 sends a second signal to the control section C described later, the first signal and the second signal being signals indicating the water level information of the tray 50. The control section C receiving the second signal displays on the display of the operation panel 16 that the water storage amount of the tray 50 is relatively small.

[0095] (6-3) Water Tank

[0096] The water tank 60 supplies water to the tray 50. The water tank 60 is supported by the casing 10 and is swingable. Specifically, as shown in FIG. 6, the water tank 60 is arranged on the inner side of the side door 18. The water tank 60 swings with the opening and closing of the side door 18. In other words, the first direction is also the direction in which the water tank 60 swings from the second posture to the first posture, and the second direction is also the direction in which the water tank 60 swings from the first posture to the second posture. The water tank 60 is configured to be detachable with respect to the casing 10. The water tank 60 has a water tank main body 61, a water supply valve 66, a water supply port 67, and a cover member 68. Figures 4-6

[0098] The water tank main body 61 is formed in a box shape. The length of the water tank main body 61 in the width direction (front-rear direction) is substantially the same as the length of the side door 18 in the width direction. The length of the water tank main body 61 in the depth direction (left-right direction) is slightly shorter than the length of the first tray 50a in the depth direction. The water tank 60 has an upper cover 63 that is detachable. In a state where the upper cover 63 is detached, the water tank main body 61 is open upward.

[0099] The water tank 60 is arranged so that the first side surface 61a of the water tank 60 extends along the inner surface of the side door 18. Specifically, the water tank main body 61 is arranged so that the first side surface 61a thereof opposes the inner surface of the side door 18.

[0100] Specifically, in the vicinity of the center of the bottom surface of the water tank main body 61, a circular communication hole 64 is formed. The communication hole 64 communicates the water tank 60 with the tray 50. Water in the water tank 60 flows into the tray 50 via the communication hole 64. On the communication hole 64, a cylindrical portion 65 extending downward toward the first tray 50a is connected. The bottom surface of the water tank main body 61 is inclined so as to cause water to flow toward the communication hole 64. At the communication hole 64, the water supply valve 66 is provided. The water supply valve 66 opens and closes the communication hole 64.

[0102] ​The water supply valve 66 is an example of the opening and closing mechanism 66 of the present disclosure. The water supply valve 66 communicates with the tray 50. The water supply valve 66 has a valve disc 66a, a valve stem 66b, a circular plate portion 66c, and a first spring member 66d.

[0103] The valve disc 66a is provided so as to close the opening portion of the communication hole 64. Specifically, the valve disc 66a is formed in a conical shape that bulges downward. By bringing the conical surface of the valve disc 66a into contact with the opening rim of the communication hole 64, the communication hole 64 is closed.

[0104] The valve stem 66b extends downward from the lower end of the valve disc 66a. The valve stem 66b is disposed inside the cylindrical portion 65. The valve stem 66b is movable up and down inside the cylindrical portion 65. The circular plate portion 66c is provided at the lower end of the valve stem 66b.

[0105] The diameter of the circular plate portion 66c is larger than the diameter of the valve stem 66b. The circular plate portion 66c is disposed directly above the contact portion 54 of the float portion 51. The circular plate portion 66c comes into contact with the contact portion 54 by the water level of the first tray 50a.

[0106] The first spring member 66d is disposed around the valve stem 66b. In other words, the valve stem 66b is inserted into the first spring member 66d. The first spring member 66d exerts a force on the water supply valve 66 toward the first tray 50a. Specifically, the first spring member 66d is fixed at the lower end of the cylindrical portion 65, and the lower end of the first spring member 66d presses the circular plate portion 66c downward.

[0107] In a state where the contact portion 54 of the float portion 51 is not in contact with the circular plate portion 66c, because the water supply valve 66 closes the communication hole 64, the outflow of the water inside the water tank 60 (inside the water tank main body 61) from the communication hole 64 is suppressed. On the other hand, when the contact portion 54 of the float portion 51 pushes the circular plate portion 66c upward (in a state where the contact portion 54 of the float portion 51 is in contact with the circular plate portion 66c), Figure 5 the water supply valve 66 rises, thereby causing the water inside the water tank 60 (inside the water tank main body 61) to flow from the communication hole 64 toward the tray 50. As such, water is supplied to the tray 50 when the water supply valve 66 is in the open state, and water is not supplied to the tray 50 when the water supply valve 66 is in the closed state.

[0108] (6-3-3) Water Supply Port

[0109] The water supply port 67 is provided on the water tank 60. The water supply port 67 communicates with the water tank 60 and supplies water inside the water tank 60 from the outside. Specifically, the water supply port 67 is formed on the upper cover 63 and communicates the outside with the inside of the water tank main body 61. The opening of the water supply port 67 is formed in the width direction (front-rear direction) of the upper cover 63.

[0110] Since the water tank 60 is fixed to the inner side of the side door 18, the water supply port 67 is arranged on the inner side of the side door 18. Therefore, when the side door 18 is in the first attitude, the water supply port 67 is exposed to the outside of the casing 10. When the side door 18 is in the second attitude, the water supply port 67 is accommodated in the inside of the casing 10. In this way, the water supply port 67 is brought to the first attitude at the time of water supply and to the second attitude at the time of non-water supply by swinging of the water tank 60.

[0111] The water supply port 67 has an inflow port 67a and an outflow port 67b. The inflow port 67a is formed at the upper end of the water supply port 67. Water from the outside flows into the inflow port 67a. The outflow port 67b is formed at the lower end of the water supply port 67. Water that has flowed into the inflow port 67a flows out to the inside of the water tank 60 from the outflow port 67b. Both the inflow port 67a and the outflow port 67b are formed in an oblong shape in the width direction (front-rear direction) of the upper cover 63. The water supply port 67 has a slope 69 that is inclined in such a manner that the opening area becomes smaller from the inflow port 67a toward the outflow port 67b. In this way, the opening area of the outflow port 67b is smaller than the opening area of the inflow port 67a.

[0112] (6-3-4) Cover member

[0113] The cover member 68 is arranged at the water supply port 67 of the upper cover 63. The cover member 68 is configured to be able to open and close the water supply port 67. Specifically, the cover member 68 is formed in a rectangular plate shape and is arranged in such a manner as to cover the inflow port 67a of the water supply port 67. When viewed from the right, the cover member 68 is configured to be supported so as to swing with the long side at the distal side and to be opened from the proximal side. On the cover member 68, a second spring member 76 that exerts a force in the opening direction is provided.

[0114] (7) Overflow suppression mechanism

[0115] The humidifying device 1 of the present embodiment has an overflow suppression mechanism K. The overflow suppression mechanism K guides water that has overflowed 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 protection portions 19, 19. The passage portion P is a gap (see FIG. 6) that is formed between the inner surface of the side door 18 and the first side surface 61a of the water tank main body 61. The upper end of the passage portion P is open, and the lower end is in communication with the first tray 50a. In this way, water that has overflowed from the water supply port 67 flows through the passage portion P and flows into the first tray 50a. Figure 4 ). The upper end of the passage portion P is open, and the lower end is in communication with the first tray 50a. In this way, water that has overflowed from the water supply port 67 flows through the passage portion P and flows into the first tray 50a.

[0116] The protection portion 19 is a plate-shaped member. The protection portion 19 is provided on the inner surface of the side door 18. A pair of protection portions 19, 19 is provided along the passage portion P in a manner of covering both ends of the first side surface 61a. Specifically, the pair of protection portions 19 is provided at both ends in the width direction (front-rear direction) of the inner surface of the side door 18 in a manner of extending in the up-down direction. The protection portion 19 communicates with the gap between the side surface of the water tank main body 61 and the first tray 50a. In this way, water overflowing from the water supply port 67 flows through the inner side of the protection portion 19 to flow into the first tray 50a. The protection portion 19 is an example of the wall portion 19 of the present disclosure.

[0117] (8) Stopper

[0118] As Figure 7 shown, the humidifying device 1 of the present embodiment includes a stopper 70. The stopper 70 is an example of the limiting member 70 of the present disclosure.

[0119] The stopper 70 is a plate-shaped member. The stopper 70 is supported on the inner side of the front face panel 13a by a third shaft portion 73 provided on the upper portion and is swingable (see Figure 1 ). The stopper 70 is urged by a spring member (omitted from the drawing) to swing in the counterclockwise direction (arrow direction of Figure 7 ) when viewed from the front. On the right edge of the stopper 70, a first engagement recess 71 and a second engagement recess 72 are aligned in the up-down direction. The first engagement recess 71 and the second engagement recess 72 engage with an engagement protrusion 75 protruding forward from the protection portion 19.

[0120] In the second posture, the first engagement recess 71 is in a state of engaging with the engagement protrusion 75 Figure 7 (a)). As the side door 18 is opened (as it is tilted in the first direction), the engagement protrusion 75 moves from the first engagement recess 71 to the second engagement recess 72 while sliding on the right edge of the stopper 70. In the first posture, the second engagement recess 72 engages with the engagement protrusion 75 Figure 7 (b)). In this way, the stopper 70 restricts the water tank 60 from being further tilted in the first direction side from the first posture.

[0121] (9) Control portion

[0122] As Figure 8 shown, the humidifying device 1 has a control portion C. The control portion C controls the operation of the humidifying device 1. In the control portion C, a microcomputer and a storage device in which software for instructing the microcomputer to work is stored are provided.

[0123] The control section C is connected to various devices of the humidifying device 1 by wire or wirelessly. For example, the control section C is connected to the water level sensor 57, the fan motor 22, the motor 44, and the operation panel 16. The control section C controls the operation of the various devices in accordance with a prescribed operation instruction (for example, an operation / stop instruction of the humidifying device 1, an execution / stop of the humidifying operation, and an execution / stop of the drying operation) sent from the operation panel 16.

[0124] (10) Operation of the humidifying device

[0125] Next, various operations of the humidifying device 1 of the present embodiment will be described.

[0126] (10-1) Humidifying operation

[0127] The humidifying operation is an operation in which the indoor air taken in is purified and humidified, and then blown out again to the indoor space. When the humidifying operation is selected on the operation panel 16, the control section C causes the fan motor 22 and the motor 44 to operate. The control section C controls the rotation speed of the fan 21 and the vaporization filter 41 in accordance with the set humidifying amount and air volume.

[0128] The indoor air taken in from the intake port 15 is transported from the air supply chamber 2 to the air purification chamber 3 by the rotation of the fan 21. The air transported to the air purification chamber 3 is purified by the air purification unit U2. The air after passing through the air purification unit U2 is transported to the humidifying chamber 4.

[0129] The air flowing into the humidifying chamber 4 passes through the rotating vaporization filter 41. Since the water is supplied from the water scooping portions 42a to adhere to the vaporization filter 41, the air passing through the vaporization filter 41 is supplied with moisture.

[0130] Although the passing air takes away the moisture of the vaporization filter 41, since the vaporization filter 41 is always rotating, the plurality of water scooping portions 42a successively supply water to the vaporization filter 41 from the second tray 50b one after another. Therefore, in the humidifying operation, the vaporization filter 41 is always in a state of containing moisture, and continuously supplies moisture to the air passing through the vaporization filter 41.

[0131] The air humidified in the humidifying chamber 4 is blown out to the indoor space from the blowout port 14. When the humidity in the indoor space reaches the target humidity, the control section C stops the humidifying operation. In this way, the humidifying operation is stopped. Note that, in this example, the following air purification operation is also performed simultaneously during the humidifying operation.

[0132] (10-2) Air purification operation

[0133] The air purification operation is an operation for purifying the indoor air taken in. When the air purification operation is selected on the operation panel 16, the control section C operates the fan motor 22. By the operation of the fan motor 22, the flow of the indoor air taken in from the suction port 15 in the air passage AP is generated toward the blowout port 14. The control section C controls the rotation speed of the fan 21 according to the set air volume.

[0134] The indoor air taken in from the suction port 15 is transported from the air supply chamber 2 to the air purification chamber 3 by the rotation of the fan 21. The air transported to the air purification chamber 3 passes through the dust collecting filter 31 and the deodorizing filter 32. The air thus purified is transported to the humidification chamber 4.

[0135] The air flowing into the humidification chamber 4 passes through the vaporization filter 41. In the case where the humidification operation is not performed, the vaporization filter 41 is stopped from operating, so that moisture is not supplied to the air passing through the vaporization filter 41. The air passing through the vaporization filter 41 is blown out to the indoor space. When an instruction to stop the operation of the humidification device 1 is sent from the operation panel 16 or a prescribed time elapses by the timer function or the like, the control section C stops the air purification operation.

[0136] (10-3) Drying operation

[0137] The drying operation is an operation for drying the vaporization filter 41 by the air supply of the fan 21 after the humidification device 1 is stopped from operating. By the drying operation, the vaporization filter 41 can be dried in a shorter time than natural drying, so that the mold prevention and the odor prevention of the vaporization filter 41 can be achieved.

[0138] The function of the drying operation can be switched on / off in the on-site setting according to the operation of the user. In this example, the function of the drying operation is turned on by pressing a plurality of buttons on the operation panel 16 in a predetermined order.

[0139] When the function of the drying operation is turned on, the control section C operates the fan motor 22 after the humidification device 1 is stopped from operating, and performs the drying operation. In the drying operation, the control section C controls the rotation speed of the fan 21 so that the air volume becomes the minimum air volume.

[0140] The indoor air taken in from the suction port 15 is transported from the air supply chamber 2 to the air purification chamber 3, the humidification chamber 4 in this order by the rotation of the fan 21. The air flowing into the humidification chamber 4 passes through the vaporization filter 41 which is stopped from operating. The vaporization filter 41 is dried by the air. The air passing through the vaporization filter 41 is blown out to the indoor space. After a prescribed time elapses, the control section C stops the drying operation.

[0141] (11) Water supply to the humidification device

[0142] Next, a water supply method for supplying water to the humidifying device 1 of the present embodiment will be described. The water supply method for supplying water to the humidifying device 1 has a first water supply method and a second water supply method. In the first water supply method, water is supplied to the water tank 60 in a state where the water tank 60 is attached to the housing 10. In the second water supply method, water is supplied to the water tank 60 after the water tank 60 is detached from the housing 10.

[0143] (11-1) First Water Supply Method

[0144] As shown in Figs. 10A and 10B, if the handle 18a of the side door 18 in the second position is pulled proximally, the side door 18 is tilted proximally so that the upper end is gradually opened. As the side door 18 is tilted toward the first direction, the water tank 60 is also gradually tilted toward the first direction. Figure 3 Figure 7 As the side door 18 is tilted, the cover member 68 is gradually opened from the proximal side. When the second engagement recess 72 of the stopper 70 is engaged with the engagement protrusion 75, the side door 18 is restricted from further swinging toward the first direction, thereby becoming the first position. In this first position, the cover member 68 is fully opened, and the water supply port 67 is changed from the closed state to the open state. As such, the cover member 68 is changed in such a manner that the water supply port 67 is in the closed state in the second position and the water supply port 67 is in the open state in the first position.

[0145] In this first position, if water is poured into the water supply port from a container (a kettle or the like) filled with water, the weight of the water tank 60 is increased, and the water tank 60 is tilted toward the second direction by the weight. However, the cover member 68 is restricted from being changed from the first position to the second position because the upper surface of the cover member 68 presses the right side panel 13c to maintain the open state of the water supply port 67 while being forced by the elastic member. Thus, it is possible to suppress the side door 18 from being closed by itself during the process of supplying water to the water tank 60. Water that overflows to the proximal side or the lateral side of the water supply port 67 or from the water supply port during the process of supplying water flows into the first tray 50a through the passage portion P and the inside of the protection portion 19.

[0146] When a predetermined amount of water is stored in the water tank 60, the water supply is completed. Then, if the side door 18 is pushed toward the second direction, the engagement protrusion 75 is disengaged from the second engagement recess 72 of the stopper 70, and the side door 18 is changed from the first position to the second position. Because the side door 18 moves toward the second direction while the upper surface of the cover member 68 presses the right side panel 13c, the side door 18 is not suddenly closed. Thus, it is possible to suppress the situation where a finger is pinched.

[0147] When a predetermined amount of water is stored in the water tank 60, the water supply is completed. Then, if the side door 18 is pushed toward the second direction, the engagement protrusion 75 is disengaged from the second engagement recess 72 of the stopper 70, and the side door 18 is changed from the first position to the second position. Because the side door 18 moves toward the second direction while the upper surface of the cover member 68 presses the right side panel 13c, the side door 18 is not suddenly closed. Thus, it is possible to suppress the situation where a finger is pinched.

[0148] ​When the side door 18 is closed to become the second posture, the engaging protrusion 75 engages with the first engaging recess 71 of the stopper 70. In this state, water is supplied from the water tank 60 to the tray 50. Specifically, if the water level of the first tray 50a is lower than the prescribed water level, the contact portion 54 of the float portion 51 pushes up the disc portion 66c of the water supply valve 66. In this way, the water supply valve 66 opens, and the water in the water tank 60 flows into the first tray 50a via the communication hole 64 of the water tank 60 (water tank main body 61). In this way, the water level of the first tray 50a rises, and the float 53 rises. As the float 53 rises, the contact portion 54 descends. When the water storage amount of the first tray 50a is filled to the prescribed water level, the contact portion 54 is separated from the disc portion 66c. When the contact portion 54 is completely separated from the disc portion 66c, the water supply valve 66 closes, and the supply of water from the water tank 60 to the tray 50 is stopped.

[0149] (11-2) Second Water Supply Method

[0150] As with the first water supply method, the side door 18 is changed from the second posture to the first posture. In the state of the first posture, if the stopper 70 is pushed downward, the second engaging recess 72 is disengaged from the engaging protrusion 75. In this way, the water tank 60 can be removed from the housing 10 together with the side door 18. Holding the water tank 60, the user moves to a kitchen or a washroom where water can be supplied, and removes the upper cover 63 from the water tank main body 61, and directly supplies water to the water tank main body 61 from a faucet. In this case, because the upper cover 63 is removed, a prescribed amount of water can be stored in the water tank main body 61 in a shorter time than when water is supplied from the water supply port 67. Note that because the water supply valve 66 closes the communication hole 64 with the first spring member 66d, leakage of water in the water tank 60 during water supply can be suppressed.

[0151] The upper cover 63 is again attached to the water tank main body 61, and the user moves again to the humidifying device 1. The engaging protrusion 75 is brought into contact with the stopper 70 to swing the stopper 70 proximally, and the water tank 60 and the side door 18 are attached to the housing 10 by pushing downward. In the state where the right edge portion 74 of the stopper 70 is in contact with the engaging protrusion 75, the side door 18 is pushed in the second direction to change the side door 18 to the second posture. After the change to the second posture, the engaging protrusion 75 engages with the first engaging recess 71 of the stopper 70. Then, as with the first water supply method, water is supplied from the water tank 60 to the tray 50.

[0152] (12) Features

[0153] (12-1)

[0154] The humidifying device 1 of the present embodiment includes a tray 50 that supplies water to the humidifying unit U3, a water tank 60 that supplies water to the tray 50, and a water supply port 67 that communicates with the water tank 60 and supplies water from the outside to the water tank 60. The water supply port 67 is arranged in a manner that can be exposed to the outside of the housing 10.

[0155] As for the existing humidifier that directly supplies water to the water tank from a faucet, in the process of detaching the water tank from the humidifier main body and attaching the water tank that has been supplied with water to the humidifier main body again, a plurality of procedures such as opening and closing the cover of the water supply port, going back and forth between the installation site of the humidifier and the installation site of the faucet, and the like are required, and some users can feel inconvenience. Therefore, in the humidifying device 1 of the present embodiment, by exposing the water supply port 67 to the outside of the housing 10, water can be directly supplied from the outside to the water tank 60 via the water supply port 67.

[0156] (12-2)

[0157] The water supply port 67 of the humidifying device 1 of the present embodiment changes between a first posture in which it is exposed to the outside of the housing 10 at the time of water supply and a second posture in which it is stored in the inside of the housing 10 at the time of non-water supply. In this way, depending on the timing of water supply, by making the water supply port 67 the first posture, water can be supplied to the inside of the water tank 60. By making the water supply port 67 the second posture at the time of non-water supply, the water supply port 67 is stored in the inside of the housing 10, and entry of dust and the like into the water supply port 67 can be suppressed.

[0158] (12-3)

[0159] The humidifying device 1 of the present embodiment further includes a side door 18 that constitutes a part of the side surface of the housing 10 and is openable and closable. The water supply port 67 is arranged on the inner side of the side door 18, the first posture is a state in which the side door 18 is open, and the second posture is a state in which the side door 18 is closed. In this way, by opening and closing the side door 18, the water supply port 67 can be changed between the first posture and the second posture. When water is supplied to the water supply port using a container such as a water pitcher, because the side door 18 is located on the side surface of the housing 10, for example, compared to the case of water supply from the top surface of the housing 10, the water pitcher does not have to be lifted, and thus water supply work can be easily performed.

[0160] (12-4)

[0161] The humidifying device 1 of the present embodiment further includes a cover member 68 that is arranged at the water supply port 67 and is openable and closable. The cover member 68 is opened and closed to expose the water supply port 67 to the outside only at the time of water supply, and thus in the state in which the cover member 68 is closed, water can be suppressed from flying out to the outside from the water supply port 67.

[0162] (12-5)

[0163] The cover member 68 of the humidifying device 1 of the present embodiment changes in the following manner: the water supply port 67 is in the open state in the first posture, and in the second posture, the water supply port 67 is in the closed state. If in the second posture, the air guide blade 17 is in the open state, dust and the like in the air can enter the inside of the housing 10 from the air outlet 14. However, because in the second posture, the water supply port 67 is closed by the cover member 68, the entry of dust into the water supply port 67 can be suppressed.

[0164] (12-6)

[0165] The cover member 68 of the humidifying device 1 of the present embodiment is urged to maintain the open state of the water supply port 67 in the first posture, and the change from the first posture to the second posture is restricted. In this way, water can be supplied without intentionally opening the cover member 68 when water is supplied to the water tank 60. Further, because the change from the first posture to the second posture is restricted, the change to the second posture during the process of supplying water in the first posture can be suppressed.

[0166] (12-7)

[0167] The water supply port 67 of the humidifying device 1 of the present embodiment is provided on the water tank 60. The water tank 60 is supported by the housing 10 and can swing, and the water supply port 67 changes between the first posture and the second posture as the water tank 60 swings. In this way, by simply swinging the water tank 60, the water supply port 67 can be changed between the closed state and the open state with ease.

[0168] (12-8)

[0169] The humidifying device 1 of the present embodiment further includes a stopper 70 that restricts the water tank 60 from further tilting to the first direction side from the first posture. With the stopper 70, the water tank 60 can be restricted from further tilting to the proximal side from the state of the first posture. As a result, the water in the water tank 60 can be suppressed from overflowing from the water supply port 67 or the water tank 60 from detaching from the housing 10 together with the side door 18.

[0170] (12-9)

[0171] The humidifying device 1 of the present embodiment further includes a water overflow suppression mechanism K that guides the 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 the process of supplying water, the water can be guided to the tray 50 by the presence of the water overflow suppression mechanism K, and thus the water can be suppressed from entering the equipment inside the housing 10. In this way, the malfunction of the humidifying device 1 can be suppressed.

[0172] (12-10)

[0173] The water overflow suppression mechanism K of the humidifying device 1 of the present 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 protection 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 overflowing between the side door 18 and the first side surface 61a of the water tank 60 can flow into the tray 50 along the passage portion P. Water overflowing to both sides of the first side surface can flow into the tray 50 along the inner surface of the protection portion 19.

[0174] (12-11)

[0175] The water tank 60 of the humidifying device 1 of the present embodiment is configured to be detachable with respect to the housing 10. The water tank 60 can also be detached to supply water. In this way, both a method of directly supplying water to the water tank and a method of supplying water by detaching the water tank 60 can be implemented.

[0176] (12-12)

[0177] The water tank 60 of the humidifying device 1 of the present embodiment includes a water supply valve 66 that communicates with the tray 50. Water is supplied to the tray 50 when the water supply valve 66 is in an open state, and water is not supplied to the tray 50 when the water supply valve 66 is in a closed state. The water supply valve 66 of the present embodiment is opened and closed by the contact portion 54 of the float portion 51 that moves up and down according to the water level of the tray 50. In this way, when the water level of the tray 50 is relatively low, the water supply valve 66 is opened, and water is supplied from the water tank 60 to the tray 50. When the water level of the tray 50 reaches the height of the full water level, the water supply valve 66 is closed, and water overflow from the tray 50 can be suppressed.

[0178] (12-13)

[0179] The water supply port 67 of the humidifying device 1 of the present embodiment includes an inflow port 67a for water inflow and an outflow port 67b for water flowing from the inflow port 67a to flow out into the water tank 60, and the opening area of the outflow port 67b is smaller than that of the inflow port 67a. In this way, by making the outflow port 67b smaller than the inflow port 67a, water can be suppressed from being scattered to the outside from the water supply port 67 due to the splashing and rebound of water flowing into the water tank 60.

[0180] (13) Other Embodiments

[0181] The above-described embodiments can also be configured as follows.

[0182] The water supply port 67 of the humidifying device 1 can also be independent of the water tank 60. The water supply port 67 can be connected to the water tank 60 by a member such as a hose, for example. In this case, water injected into the water supply port 67 flows into the water tank 60 through the hose.

[0183] The water tank 60 of the humidifying device 1 can also be incapable of being disassembled with respect to the housing 10 (fixed to the housing 10).

[0184] The side door 18 of the humidifying device 1 can also be a horizontally opening door. For example, the side door 18 can also swing so that its left end or right end opens. The humidifying device 1 can also be configured so that the side door 18 and the water tank 60 are pulled out from the housing 10 to the outside by a so-called drawer configuration, thereby exposing the water supply port 67 to the outside. Also, the air purifying unit U2 and the humidifying unit U3 of the present embodiment can also be configured like the air purifying unit and the humidifying element described in Patent Document 1 (for example, Figs. 1 and 2), respectively. Figure 3 ).

[0185] The stopper 70 of the humidifying device 1 can also have a damper configuration so as to suppress the side door 18 from suddenly closing when the side door 18 changes from the first attitude to the second attitude. For example, the damper configuration can also be a gear damper. The gear damper has a gear formed along the left edge portion of the stopper 70. The gear suppresses the side door 18 from suddenly changing from the first attitude to the second attitude by engaging with an engaging portion (omitted from illustration) fixed to the inner side of the front panel 13a. In this way, it is possible to suppress the side door 18 from closing on its own due to the weight of the water in the water tank 60 during water supply, and further, it is possible to avoid the fingers from being pinched by the side door 18 and the right side panel 13c. In addition, if the stopper 70 has the above-described damper configuration, it is not necessary to provide the cover member 68 that maintains the first attitude as in the above-described embodiment.

[0186] The overflow suppressing mechanism K of the present embodiment can also not have the protection portion 19, as long as it is configured to guide the water overflowing from the water supply port 67 to the tray 50.

[0187] The above-described embodiments and modified examples have been described, but it should be understood that various changes can be made to the modes and details thereof without departing from the spirit and scope of the claims. The above-described embodiments and modified examples can also be appropriately combined or replaced as long as the functions of the object of the present disclosure are not affected. The words "first", "second", and the like described above are used only to distinguish the sentences containing the words, and do not limit the number and order of the sentences.
