[Technical Field]

[0001] The present invention relates to a water supply device and a humidifier using the same. [Background technology]

[0002] For example, Patent Document 1 describes a humidifier that is composed of a water storage device that stores supplied water, a water supply tank that supplies water, and a cap that can be attached and detached to the water supply tank, with a cylindrical portion that protrudes downward from the peripheral edge of the cap and an outer cylindrical portion that protrudes downward outward from the cylindrical portion, and has a notch that has an upper end near the bottom surface of the cap and extends to the lower ends of the cylindrical portion and the outer cylindrical portion.

[0003] This cutout portion prevents the lower end surfaces of the cylindrical portion and the outer cylindrical portion from forming a horizontal plane, making it difficult for surface tension to be generated to hold water remaining at the edge of the lower end opening, and preventing the floor from getting wet when the water tank is removed from the water storage device and carried around.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-145238 Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, the water level at which water supply from the water tank is stopped is near the upper end of the notch, so most of the cylindrical part and outer cylindrical part are immersed in water. Therefore, even if the surface tension is kept low, the area immersed in water is large, so a lot of water adheres to the cap, and there is a risk that dripping while the water tank is being carried cannot be sufficiently prevented. [Means for solving the problem]

[0006] In order to solve the above problem, the water supply device of claim 1 of the present invention comprises a water tank for storing water, a water supply tank that is detachably attached to the water tank, a water supply port that is attached to the water supply tank and supplies water to the water tank and has a cylindrical water supply tube portion, a valve mechanism that is attached to the water supply tank and opens and closes the water supply port, and a pin-shaped portion that is attached to the water tank and protrudes toward the valve mechanism when the water supply tank is attached, and a cylindrical portion that stands around the pin-shaped portion and has a water hole below it, and when the water supply tank is attached to the water tank, the pin-shaped portion comes into contact with the valve mechanism and the pin-shaped portion begins to push up the valve mechanism, opening the water supply port and enabling water to be supplied to the water tank, and is characterized in that contact portions are provided at the bottom of the water supply tube and at the top of the cylindrical portion so that the water supply port is in a water supply ready state when the water supply tube and the cylindrical portion come into contact and become sealed.

[0007] In addition, in the water supply device of claim 2, the position at which the pin-shaped portion contacts the valve mechanism and begins the action is characterized by being a position below the upper end of the cylindrical portion, and / or a position above the lower end of the water supply tube portion.

[0008] The water supply device according to claim 3 is characterized in that a sealant is provided at the contact portion of either the tubular water supply portion or the cylindrical portion.

[0009] In addition, in the water supply device of claim 4, the water supply tank has a cap equipped with the water supply port and the valve mechanism, and when the water supply tank is attached to the water tank, the bottom of the cap is positioned below the water supply port and above the water passage hole.

[0010] In addition, the water supply device according to claim 5 is characterized in that a protrusion is provided at the lower end of the valve mechanism to cause water droplets adhering to the valve mechanism to fall downward.

[0011] In addition, a humidifier equipped with a water supply device as claimed in claim 6 is characterized in that it comprises a humidified air generating means installed in the water tank for generating humidified air, a housing having an intake port for drawing in outside air and an outlet port for blowing out the humidified air, a blower fan installed in a flow path from the intake port through the humidified air generating means to the outlet port for circulating air, and a control unit which performs humidification operation by controlling the operation of the blower fan. [Effects of the Invention]

[0012] According to the present invention, the outer periphery of the water supply port is not submerged in water when supplying water, and the water supply tube portion can be drained well when the water supply tank is removed, so that the amount of water adhering to the water supply port can be reduced and dripping of water can be sufficiently suppressed when the water supply tank is being carried.

[0014] Next, a water supply device and a humidifier using the same according to an embodiment of the present invention will be described with reference to the drawings.

[0015] In the following description, the terms "front (front face)," "rear (rear face)," "upper," "lower," "right," and "left" follow the definitions in Figures 1 to 12. The up-down direction corresponds to the vertical direction when the humidifier 100 is installed. The front-rear direction and the left-right direction correspond to the horizontal direction when the humidifier 100 is installed.

[0016] Reference numeral 1 denotes the housing of humidifier 100, and reference numeral 2 denotes a water tank located at the bottom of housing 1, to which water is supplied by a cartridge-type water tank 3. Water tank 3 is inserted into housing 1 from the top, placed on top of water tank 2, and supplies a fixed amount of water to water tank 2. Reference numeral 4 denotes an intake port that takes dry air (dry air) from the room into housing 1 and opens to the side of housing 1. Reference numeral 5 denotes an outlet port that sends moist air (humidified air) into the room and opens to the top of housing 1. Reference numeral 6 denotes a blower fan such as a sirocco fan that is installed in air flow path 12 from intake port 4 to outlet port 5, and reference numeral 7 denotes a motor that drives blower fan 6. Downstream of blower fan 6 are installed a heater 8 that heats the air and a vertically rectangular evaporative filter 9 made of pleated, highly absorbent sheet-like material. The vaporization filter 9 is attached so as to be freely rotatable, and both ends thereof are alternately immersed in the water in the water tank 2, and the water is sucked up by capillary action so as to be distributed over the entire surface.

[0017] Dry air taken in from the room by the blower fan 6 through the air inlet 4 passes through the heater 8 and then passes through the evaporative filter 9 moistened by the water in the water tank 2 to become humidified air, which is then sent out into the room through the air outlet 5. Reference numeral 12 denotes an air flow path through which the air blown by the blower fan 6 flows within the housing 1. Air flow path 12 is a flow path that runs from the air inlet 4, via the evaporative filter 9, to the air outlet 5.

[0018] Reference numeral 13 denotes a fan casing that is installed to surround the outer periphery of the blower fan 6. Air drawn into the center of the blower fan 6 from the intake port 4 is blown out centrifugally from the outer periphery of the blower fan 6, flows through a spiral air path (not shown) inside the fan casing 13 in the direction of rotation of the blower fan 6, and is sent out to the air path 12 on the downstream side.

[0019] Reference numeral 14 denotes a filter casing that is installed to surround the upper part of the evaporation filter 9. The filter casing 14 is molded integrally with the fan casing 13.

[0020] Reference numeral 15 denotes an air filter such as a HEPA filter made of sheet-like filtering material such as nonwoven fabric, which purifies the air taken in through the intake port 4 by capturing fine dust particles and minute particles such as PM2.5, and can be freely attached and detached to an attachment part (not shown) formed on the intake port 4.

[0021] Water tub 2 has a water supply section 10, which is supplied with water from water supply tank 3, and a vaporization filter installation section 11, which is installed with a vaporization filter 9, arranged side by side, and both are molded integrally from resin, and communicate with each other through communication port 32 at the bottom, storing the same level of water. Water tub 2 can be removed by pulling pull handle 16 from the back of housing 1.

[0022] Reference numeral 17 denotes a frame that surrounds the vaporization filter 9 and houses the vaporization filter 9. A rotation fulcrum 18 and a joint 20 are integrally provided on the frame 17 on the same axis at approximately the center of the top and bottom and the left and right.

[0023] Reference numeral 24 denotes a turn motor for rotating the vaporization filter 9, and is provided inside the front surface of the housing 1 opposite the joint 20. A rotation shaft 25 of the turn motor 24 is fitted into the joint 20, so that the joint 20 is detachably supported by the rotation shaft 25. As a result, by driving the turn motor 24, the joint 20 can be rotated, and the vaporization filter 9 can be rotated around the fulcrum 18 and the joint 20 as the rotation center.

[0024] Reference numeral 19 denotes a fulcrum receiving portion provided on the water tank 2, which serves as a bearing portion for the fulcrum 18 that rotates as the vaporization filter 9 rotates.

[0025] Reference numeral 26 denotes a lever pivotally supported at one end, with the lower surface of the tip facing a cam 27 provided on joint 20 and the approximate center of the upper surface facing a position detection switch 28. When turn motor 24 is driven to rotate vaporization filter 9, cam 27 pushes up lever 26, turning on position detection switch 28, which controls turn motor 24 so that vaporization filter 9 stops at a specified position.

[0026] Here, the configuration of the water supply device 21 shown in Figs. 8 to 10 will be described.

[0027] Reference numeral 29 denotes a removable cap that serves as the lid for the water supply tank 3. Cap 29 is provided with a water supply port 50 that supplies water to the water tank 2 and a valve mechanism 51 that opens and closes the water supply port 50. Water supply port 50 has a cylindrical water supply tube portion 50a at its bottom. Valve mechanism 51 is regulated by a compression spring (not shown) so that water supply port 50 is always closed. When water supply tank 3 is inserted into and attached to the water supply unit 10 of the water tank 2, the upper end of pin-shaped portion 30 erected on the water supply unit 10 abuts against the lower end of valve stem 51a of valve mechanism 51, pushing up valve stem 51a to open the valve. In other words, the water supply port 50 is opened, creating a water supply enabled state in which water can be supplied to the water tank 2 (water supply unit 10).

[0028] Furthermore, a cylindrical portion 60 is erected around the pin-shaped portion 30, and a water passage hole 60a is opened at the bottom of the cylindrical portion 60. When water is supplied from the water supply tank 3, it flows from the water supply port 50 through the inside of the cylindrical portion 60, passes through the water passage hole 60a, and is supplied to the water supply portion 10.

[0029] After the water supply tank 3 is attached to the water tank 2, the cap bottom 52, which is the lower end of the cap 29, abuts against a receiving member 61 provided in the water supply section 10 of the water tank 2, thereby stably placing the water supply tank 3 in the water supply section 10.

[0030] In addition, in a water supply enabled state where water can be supplied from water supply tank 3 to water tank 2 (water supply section 10), the lower part of water supply tubular section 50a and the upper part of cylindrical section 60 come into contact with each other via sealing material 70, forming contact section 71. Details of water supply device 21 will be described later.

[0031] Reference numeral 31 denotes a float sensor provided in water supply section 10, which detects the presence of water level and outputs a water level detection signal when water is stored above a certain level in water supply section 10 and evaporation filter installation section 11. Reference numeral 33 denotes a humidity sensor provided in air supply path 12 to detect the humidity in the room where humidifier 100 is installed.

[0032] An operation unit 34 is provided with a plurality of switches and is used to issue various operation commands. The operation unit 34 is provided with an operation switch for starting and stopping the humidification operation, a switch for setting the humidity, an operation changeover switch for setting the strength of the humidification operation, a drying switch for starting a filter drying operation for drying the evaporative filter 9, and the like.

[0033] The operation unit 34 is also provided with lamps corresponding to each switch, including an operation lamp that lights up when the operation switch is operated, a lamp that displays the set humidity, and a lamp that displays the operation state switched by the operation changeover switch.

[0034] Reference numeral 35 denotes a control unit made up of a microcomputer that controls the operation based on the detection values ​​detected by the float sensor 31 and humidity sensor 33 and the settings of the switches provided on the operation unit 34. The control unit 35 is equipped with a blower fan control means 40 that drives the blower fan 6 at a predetermined rotation speed, a heater control means 41 that changes the ON / OFF state of the heater 8, a turn motor control means 42 that controls the operation of the turn motor 24 that rotates the evaporation filter 9, and a timer 43 that serves as timing means for counting the time that has elapsed since the start of a specific operation. The control unit 35 changes the rotation speed of the blower fan 6 to adjust the amount of humidification so that the indoor humidity reaches the target humidity, thereby carrying out the humidification operation.

[0035] Humidified air generating means for generating humidified air is configured by the vaporization filter 9 and the frame 17. In other words, the humidifier 100 in this embodiment is an evaporation-type humidified air generating means.

[0036] Next, the operation from the start to the end of operation in one embodiment of the present invention will be described.

[0037] When the humidifier is operated, water is placed in the water tank 3 and the water tank 2 is filled with water. A certain amount of water flows from the water tank 3 into the water tank 2, immersing the lower end of the vertically-installed vaporization filter 9. This causes the vaporization filter 9 to absorb the water and become moist.

[0038] At this time, when the operation switch of the operation unit 34 is operated, the control unit 35 drives the blower fan 6 to draw in dry air from the room through the intake port 4. The dry air blown out by the blower fan 6 is heated by the heater 8 provided in the air flow path 12. Then, as shown in FIG. 2 , the heated dry air passes through the evaporative filter 9, which is moistened by submerging one end of the filter in the water tank 2, and the water in the evaporative filter 9 vaporizes to become humidified air, which is then released into the room through the air outlet 5.

[0039] Furthermore, when operation begins with the lower end of vaporization filter 9 submerged, timer 43 in control unit 35 counts a predetermined time. After the predetermined time has elapsed, vaporization filter 9 is rotated approximately 180 degrees and stopped with the other end that was not submerged submerged. Vaporization filter 9 then absorbs water again and becomes moist, and the air that passes through vaporization filter 9 vaporizes the water and is then discharged as humidified air.

[0040] Thereafter, this operation is repeated to continue the humidifying operation. At this time, the rotation direction of the vaporization filter 9 may be either forward or reverse.

[0041] After humidification is complete, the evaporative filter 9 is rotated approximately 90° from the state shown in Figure 2 and is held above the water surface in a generally horizontal position relative to the water surface of the water tank 2, as shown in Figure 3. Then, a predetermined time is counted by the timer 43 in the control unit 35, during which time a drying operation is performed to dry the evaporative filter 9 using air heated by the heater 8 provided in the air flow path 12.

[0042] After the drying operation is completed, if the evaporation filter 9 and water tank 2 are to be removed from the housing 1 for cleaning or the like, they can be removed by pulling out the pull-out handle 16 of the housing 1 in the direction of the arrow shown in Fig. 1. As shown in Fig. 4, the evaporation filter 9 and water tank 2 are detachable, so that the water tank 2 can be cleaned after removing the evaporation filter 9.

[0043] Next, details of the water supply device 21 in the first embodiment of the present invention will be described with reference to FIGS.

[0044] 8 shows the water supply device 21 before the water supply tank 3 is attached to the water tub 2. The water supply port 50 is closed by the valve mechanism 51, and water in the water supply tank 3 is not supplied to the water tub 2.

[0045] 9 shows the water supply device 21 when the water supply tank 3 is being attached to the water tank 2, and just before the pin-shaped portion 30 comes into contact with the lower end of the valve stem 51a and starts to push up the valve mechanism 51. At this time, the lower portion of the water supply tubular portion 50a and the upper portion of the cylindrical portion 60 form a contact portion 71 where they come into contact via the sealing material 70, and the water supply tubular portion 50a and the cylindrical portion 60 are in a sealed state. Air and Once this sealed state is achieved, the pin-shaped portion 30 begins to push up the lower end of the valve shaft 51a, creating a water supply enabled state, and water begins to be supplied from the water supply port 50 to the aquarium 2.

[0046] The sealing material 70 has a flange portion 70a protruding radially outward from its upper portion and a circumferentially continuous annular protrusion 70b on its inner surface. The sealing material 70 is secured to the cylindrical portion 60 by the flange portion 70a. The annular protrusion 70b protrudes radially inward. When the water supply tube 50a is inserted into the sealing material 70 secured to the cylindrical portion 60, the annular protrusion 70b elastically deforms and adheres tightly to the sealing material 70. Furthermore, because the annular protrusion 70b is easily elastically deformed, the water supply tube 50a is more easily inserted into the cylindrical portion 60 and the sealing material 70 than if the inner surface of the sealing material 70 were flat. Therefore, the sealing material 70 improves the airtightness between the water supply tube 50a and the cylindrical portion 60 while facilitating insertion and removal of the water supply tube 50a. The sealing material 70 is made of, for example, silicone rubber, which is elastic and highly water-resistant.

[0047] Here, once the tubular water supply portion 50a and the cylindrical portion 60 are sealed and the water supply is enabled, water in the water supply tank 3 is supplied to the water tub 2 through the water passage 60a, while air in the water tub 2 is supplied to the water supply tank 3 through the water passage 60a. That is, as shown in FIG. 10 , after the water supply tank 3 is attached to the water tub 2, the water level W in the water tub 2 is maintained at the upper end of the water passage 60a. This prevents the cap 29 on the outside of the water supply port 50 (outside the tubular water supply portion 50a) from being submerged in the water level W, preventing the cap 29 from getting wet. Therefore, when the water supply tank 3 is removed from the water tub 2 and carried around for refilling water, for example, water does not drip from the cap 29. Furthermore, when the cap bottom 52 is placed on a room floor, the floor surface opposite the cap bottom 52 will not get wet.

[0048] Here, in order to prevent cap 29 from being submerged in water surface W and getting wet, cap bottom 52 must be positioned above the upper end of water hole 60a after attaching water supply tank 3 in Figure 10. Also, in order to place cap bottom 52 on the indoor floor as the bottom surface, cap bottom 52 must be positioned below the lower end of tubular water supply portion 50a. This prevents cap 29 from getting wet and allows water supply tank 3 to easily stand on its own.

[0049] If the cylindrical portion 60 and the water passage hole 60a were not present, the water level W after the water supply tank 3 was attached would be at the bottom end of the tubular water supply portion 50a, causing part of the cap 29 and the cap bottom portion 52 to be submerged in the water tub 2, resulting in water dripping when the water supply tank 3 was carried. Furthermore, if the water supply tank 3 was in a water-supplyable state before the tubular water supply portion 50a and the cylindrical portion 60 were sealed, water would be supplied to the water tub 2 from between the tubular water supply portion 50a and the cylindrical portion 60. Therefore, if a large amount of water is supplied, the water level W in the water tub 2 may be higher than the top end of the water passage hole 60a, potentially causing part of the cap 29 to be submerged in the water tub 2. On the other hand, in this embodiment, a configuration can be realized in which the cap 29 does not get wet, as described above, and therefore water dripping from the cap 29 can be prevented when the water supply tank 3 is being carried.

[0050] 9, the position P1 at which pin-shaped portion 30 starts to push up valve mechanism 51 (push-up action start position) is below the upper end of cylindrical portion 60 and above the lower end of tubular water supply portion 50a. This ensures that contact portion 71 is formed before water supply is enabled.

[0051] In this embodiment, a sealant 70 is used to improve the sealing performance between the water supply tubular portion 50a and the cylindrical portion 60. .Ma Furthermore, sealing material 70 is provided on the cylindrical portion 60 side. That is, it is provided at cylindrical portion-side contact portion 71b, which is the contact portion on the cylindrical portion 60 side. Note that sealing material 70 may also be provided on the tubular water supply portion 50a side, that is, at tubular water supply portion-side contact portion 71a; either is acceptable as long as it can improve the airtightness between tubular water supply portion 50a and cylindrical portion 60 when forming contact portion 71.

[0052] It is also possible to form contact area 71 between tubular water supply portion 50a and cylindrical portion 60 alone, without using sealing material 70 in this embodiment. Figure 13 shows a portion of water supply device 21 in a second embodiment of the present invention. Here, contact area 71 is formed by direct contact between tubular water supply portion side contact portion 71a and cylindrical portion side contact portion 71b. If this improves the sealing performance between tubular water supply portion 50a and cylindrical portion 60, the effects of the present invention will be similarly achieved.

[0053] 14 shows a portion of water supply device 21 according to the third embodiment of the present invention. Here, when contact portion 71 is formed, P2, which is the starting position of the pushing-up action, is below the upper end of cylindrical portion 60, but is below, not above, the lower end of tubular water supply portion 50a.

[0054] 15 shows a portion of water supply device 21 according to a fourth embodiment of the present invention. Here, when contact portion 71 is formed, P3, which is the start position of the pushing-up action, is above the lower end of tubular water supply portion 50a, but above the upper end of cylindrical portion 60, not below.

[0055] In other words, when the contact portion 71 is formed, the water supply is possible as long as the push-up action start position is either below the upper end of the cylindrical portion 60 or above the lower end of the tubular water supply portion 50a. This improves the degree of freedom in designing the valve shaft 51a and the pin-shaped portion 30 compared to Figures 9 and 13.

[0056] Furthermore, when removing the water supply tank 3 from the water tub 2 after the water supply tank 3 has been attached, the water supply tubular portion 50a and the cylindrical portion 60 (or the sealing material 70) that were in contact with each other are displaced from each other. separation At this time, the water filled inside the water supply tubular portion 50a and the cylindrical portion 60 flows downward due to gravity, but the water adhering to the lower end of the water supply tubular portion 50a separation Due to the action of surface tension at the upper end of cylindrical portion 60, which was in contact with tubular water supply portion 50a until just before it was removed, the water does not remain in tubular water supply portion 50a but flows toward cylindrical portion 60. In other words, the water that had been adhering to the lower end of tubular water supply portion 50a smoothly drains down into water tub 2 below, which sufficiently prevents water from dripping when water supply tank 3 is removed from water tub 2 and then carried.

[0057] Furthermore, when the water supply tank 3 is removed from the water tub 2, water also drips from the valve mechanism 51 and valve stem 51a inside the water supply tubular portion 50a. Here, as shown in FIG. 11, by providing a protrusion 53 at the lower end of the valve stem 51a, water adhering to the valve mechanism 51 and valve stem 51a can be guided via the protrusion 53 to the water tub 2 below. This makes it possible to sufficiently prevent water from dripping when the water supply tank 3 is removed from the water tub 2 and then carried.

[0058] In this embodiment, a water supply port 50 and a valve mechanism 51 are provided, and a detachable cap 29 is used for the water supply tank 3. This improves workability by removing the cap 29 when refilling water into the water supply tank 3.

[0059] It should be noted that the water supply tank 3 in this embodiment may be configured to have the water supply port 50 and valve mechanism 51 provided thereon, without using the detachable cap 29. Specifically, the configuration is one in which the cap 29 is integrated with the water supply tank 3. In other words, the configuration is such that the water supply tank is ready for water supply after the tubular water supply portion 50a and the cylindrical portion 60 form contact portion 71, and as long as the outside of the water supply port 50 (the outside of the tubular water supply portion 50a) is not immersed in the water surface W, the detachable cap 29 is not necessary.

[0060] In addition, in this embodiment, the water supply tube portion 50a is on the inside and the cylindrical portion 60 is on the outside, constituting the contact portion 71, but the inside-outside positional relationship may be reversed. In other words, the water supply tube portion 50a may be on the outside and the cylindrical portion 60 on the inside, constituting the contact portion 71.

[0061] Furthermore, in the embodiment of the present invention, the blower fan 6 is disposed upstream of the vaporization filter 9, but it may also be disposed downstream of the vaporization filter 9. In other words, it may be disposed so as to push air in from upstream of the vaporization filter 9, or so as to pull air in from downstream of the vaporization filter 9.

[0062] In addition, in this embodiment, the humidifying method of humidifier 100 is configured as an evaporative method, but a humidifying method other than evaporative method may be used. In other words, even if the water supply device of the present invention is applied to a humidifying device of a steam type, ultrasonic type, water crushing type, or the like, the effects of the present invention will be similarly achieved.

[0063] Furthermore, the other configurations used in the present embodiment are presented as examples and are not intended to limit the scope of the invention, and the invention can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are also included in the inventions described in the claims and their equivalents.
