Description

Liquid supply device, humidification device and container

The present invention relates to a liquid supply device, a humidification device, and a container having a function of purifying stored liquid.

The indoor air contains various substances that are uncomfortable or harmful to the human body, such as dust, pollen, tobacco smoke, and exhaled air. Particularly in recent years, since the houses are airtight, such harmful substances are likely to stay in the room. For this reason, natural ventilation has been provided by opening windows in rooms as appropriate.

However, it is a fact that natural ventilation cannot be performed as desired in areas where air pollution is severe, and in homes and workplaces where people suffer from hay fever. Under such circumstances, air purifiers having an air purifying function for purifying indoor air have been widely spread.

The air cleaner has a purification filter attached to the front, and a ventilation path with a blower is formed inside. The ventilation path extends from the front opening to the upper outlet. In such an air purifier, the air in the room, which is external air, is sucked into the ventilation path through the purification filter according to the rotation of the blower, and the sucked air is blown out from the air outlet to the room, which is outside. At that time, harmful substances contained in the air are removed by being collected, adsorbed and decomposed by the purification filter, thereby purifying the air.

Some air purifiers have a humidifying function for the purpose of adjusting the indoor air to a more comfortable state. In an air purifier with a humidifying function, a humidifying filter containing moisture is arranged to block a part of the cross-sectional area of the ventilation path, and a part of the air purified by the purifying filter passes through the humidifying filter. It is configured to take in moisture when it is done and to be humidified thereby (see, for example, Patent Document 1). There is also known a humidifying device that rotates a disk-shaped humidifying filter arranged in a vertical posture in order to efficiently absorb water in the entire humidifying filter (see, for example, Patent Document 2).

The humidifying device as in Patent Document 2 includes a water tank for storing water, and the humidifying filter is arranged in a vertical posture so that a part of the circumferential direction is submerged in the water tank, and is placed at the central position of the humidifying filter. It is configured to be able to rotate in the circumferential direction around a rotation shaft in a lateral posture orthogonal to the side surface. By rotating in the circumferential direction, the humidifying filter is continuously submerged in the circumferential direction, and water is sucked up from the submerged part to the non-submerged part, so that the entire humidifying filter spreads. As a result, the humidifying filter efficiently absorbs water throughout the entire humidifying filter.

Furthermore, by blowing air to one side of the humidified filter that has absorbed water, the air that has passed through the humidified filter absorbs moisture, and the absorbed air is blown to the outside of the humidifier.

By the way, since water is always stored in the water tank of the conventional humidifier and the humidifying filter is always in a wet state, when antibacterial measures are not taken, bacteria and molds are likely to be generated.
For this reason, in a conventional humidifier, a sheet containing an antibacterial component (antibacterial sheet) is laid on the bottom of the water tank, or a solid antibacterial agent is introduced into the water supply tank for supplying water to the water tank. It was done.

However, the technique of laying an antibacterial sheet at the bottom of a water tank or introducing an antibacterial agent into the tank has a problem that the antibacterial component elution efficiency from the antibacterial agent is low and the antibacterial function cannot be fully exhibited. Was.

Also, in the method of laying an antibacterial sheet on the bottom of the aquarium, when replacing a sheet that has reached the end of its antibacterial function, the water tank must be removed from the humidifier, the humidification filter removed, and a new antibacterial sheet laid. Therefore, there is a problem that it takes time to replace the antibacterial sheet.
On the other hand, in the method of introducing a solid antibacterial agent into the water supply tank, the antibacterial agent may fall from the water supply tank each time water is supplied.

The present invention has been made in view of such circumstances, and is a liquid supply device that can sufficiently exhibit an antibacterial function and can be easily replaced with a new one when the life as an antibacterial function is finished. An object is to provide a humidifier and a container.

A liquid supply apparatus according to the present invention includes a tank having a valve body that is biased downward to close a liquid outlet formed at the bottom, and the tank is detachably mounted. And a tank mounting part provided with a valve operating part for opening the liquid outlet by pushing up the valve body in the case where the liquid is stored in the tank attached to the tank mounting part. In the liquid supply apparatus for supplying to the outside through the outlet, a storage member having a plurality of holes through which the liquid stored in the tank flows and in which a solid substance is stored can be attached to the inside of the tank. It is characterized by being.

In the liquid supply apparatus according to the present invention, the tank includes a cylindrical liquid replenishing port projecting downward at the bottom, and a cap detachably attached to the liquid replenishing port. A valve body is provided on the cap.

In the liquid supply device according to the present invention, the storage member includes a storage portion that stores the solid substance and a leg portion that can be attached to the cap, and a part of the hole of the storage member is It is provided so as to communicate with the liquid outlet.

In the humidifying device according to the present invention, the solid substance is an antibacterial agent, the liquid supply device according to any one of the above-described inventions, and means for vaporizing the liquid supplied from the liquid supply device It is characterized by providing.

The container according to the present invention includes a cylindrical liquid replenishing port protruding from the bottom and a cap that is detachably attached to the liquid replenishing port, and is arranged in a predetermined direction to close the liquid outlet and the liquid outlet. A container that can be attached to the inside of a tank provided on the cap with a valve body that is biased toward the cap, and includes a storage portion that stores a solid substance, and a leg portion that can be attached to the cap. The storage part and the leg part have a plurality of holes through which the liquid stored in the tank flows.

In the present invention, when the antibacterial agent is stored in the storage member, the liquid is taken in from the outside of the storage member during water supply. The liquid taken in the inside of the housing member dissolves the antibacterial component from the contained antibacterial agent, so that the liquid well containing the antibacterial component flows from the hole to the outside. Air introduced from the outside of the tank is taken into the space inside the housing member through the hole. The antibacterial agent housed in the housing member moderately disturbs and collides with the flow of air introduced into the housing member, so that the dissolution of the antibacterial component proceeds and the liquid containing the antibacterial component diffuses to the outside of the housing member. .

According to the present invention, since the antibacterial component contained in the antibacterial agent can be dissolved using the flow of liquid and air introduced when the tank is supplied, compared with the case where the antibacterial agent is simply put into the tank. , Elution efficiency can be increased.

Hereinafter, as an embodiment of a liquid supply device and a humidifying device according to the present invention, an embodiment applied to an air purifier having a humidifying function will be specifically described with reference to the drawings.

FIG. 1 is an exploded perspective view showing the configuration of the air cleaner according to the present embodiment, and FIG. 2 is a longitudinal sectional view showing the internal configuration of the air cleaner. In this embodiment, an example of an air cleaner having a humidifying function and an ion releasing function will be described.

The air cleaner shown in the figure is placed on the floor or hung on a wall at a suitable place in the room during operation. In general, the housing 1 has a suction port 1a on the rear surface, and a suction port 1a of the housing 1. And the outer panel is constituted by the rear panel 2 having a plurality of small holes. The housing 1 has a rectangular parallelepiped shape as a whole, and has an external shape that stands vertically. A filter housing portion 1b that is greatly recessed in a rectangular parallelepiped shape is formed on the rear surface, and the humidifying filter 3 and the water tank are formed on one side surface. An insertion portion 1c for inserting 4 from the lateral direction is formed. In the filter storage part 1b, the deodorizing filter 6 and the dust collection filter 7 as a purification filter are stored in an overlapped order from the rear side.

The deodorizing filter 6 is responsible for adsorbing odorous components such as acetaldehyde, ammonia and acetic acid in the air. A non-woven fabric made of polyester is attached to a rectangular frame, and activated carbon is uniformly distributed on the frame. A polyester non-woven fabric is put on the top.

The dust collection filter 7 plays a role of collecting fine dust, and is a so-called HEPA (High Efficiency Particulate Air) filter. The aggregate is made of polyester / vinylon non-woven fabric and electroblown melt blown non-woven fabric. The antibacterial sheet made of a non-woven fabric subjected to hydroxyapatite processing is overlapped on the upper and lower surfaces of the folded anti-woven sheet and thermocompression bonded, and a frame made of a non-woven fabric with hot melt is welded.

The deodorizing filter 6 and the dust collecting filter 7 stored in the filter storage unit 1b are prevented from falling off from the filter storage unit 1b by the rear panel 2. The rear panel 2 has a substantially rectangular shape, a plurality of ventilation holes 2a are formed in a matrix, and a fiber sheet on a mesh is pasted on the back surface.

The rear panel 2 is attached to the rear surface of the housing 1 in which the deodorizing filter 6 and the dust collecting filter 7 are housed, and is completely covered by the rear panel 2 including the deodorizing filter 6 and the dust collecting filter 7. It is.

The rear panel 2 is supported by being hooked and supported on the upper part of the housing 1 by hooks 2b bent from the upper part toward the housing 1, and fixed by a locking part 2c.

In the housing 1, a blower 8 is disposed on the front side of the filter storage portion 1b with the

partition walls

11 and 12 interposed therebetween. The blower 8 includes a fan 81 and a fan motor 82 that drives the fan 81, and the front side is isolated by the partition wall 12. Further, a fan motor 82 is fixed to the front partition 12, and a plurality of ventilation holes communicating with the blower 8 are formed in the rear partition 11. Although the fan 81 is a turbo fan, a propeller fan or a cross flow fan can also be employed, and the type of fan is not particularly limited. In the case of a turbo fan, the thickness is made larger than the diameter of the fan so as to lower the noise level. The fan motor 82 uses a direct current motor with emphasis on the ease of drive control.

Further, a protective cover is provided on the front side of the filter housing portion 1b so that the humidifying filter 3 and the rotation driving mechanism 9 that rotates the humidifying filter 3 are not directly touched, and an opening through which air passes is formed. Yes.

In the housing 1, a blow-out passage 13 is formed by

partition walls

11 and 12 in an upper portion corresponding to the upper side of the blower 8, and the blow-out passage 13 communicates with a blow-out opening 14 that opens upward. 14 is provided with a wind direction plate 15. On the upper part of the housing 1, there are provided an operation / display unit comprising operation buttons for turning on / off the power and setting operation, a display lamp for displaying the operation state, and the like.

The wind direction plate 15 is driven by a driving means such as a stepping motor in order to blow an air flow in an oblique direction or a range from the horizontal direction to the upward direction, and is driven in a predetermined range from the oblique direction or the horizontal direction to the upward direction.

External air (indoor air) is introduced from the vent 2a of the rear panel 2 in accordance with the driving of the blower 8, that is, the rotation of the fan 81 by the fan motor 82. The introduced air is purified by the deodorizing filter 6 into air having no odor or dust. The purified air is sucked into the central portion of the fan 81 from the vent hole of the partition wall 12 through the ventilation path. The air sucked into the central portion of the fan 81 passes between the fan blades, is discharged from the outer periphery of the fan 81, is guided upward, and is blown out into the outside room by the direction of the air outlet 14 and the wind direction plate 15. .

Rotating humidifying filter 3 is arranged in the ventilation path leading from deodorizing filter 6 and dust collection filter 7 to blower 8. Specifically, in the lower part of the housing 1, a water tank 4 that can be attached and detached from one side, and a disk-shaped humidifying filter 3 is disposed above the water tank 4 so as to be rotatable.

The water tank 4 is connected to one side of the water supply part 4a and the water supply part 4a arranged on the lower side of the water supply tank 5 arranged on the side surface of the housing 1, and is inserted into the housing 1 from the insertion part 1c of the housing 1. It has a T-shape in a plan view having a water storage portion 4b, and

shaft support portions

10, 10 are held on both sides of the water storage portion 4b, together with the humidifying filter 3 attached to the top of the

shaft support portions

10, 10. The water storage part 4b can be taken out from the insertion part 1c, and water is supplied to the water storage part 4b from the water supply tank 5 through the water supply part 4a in a timely manner, and water is stored at a constant water level.

The humidifying filter 3 as a filter has water absorption and air permeability, and is composed of a disk-shaped filter body 31 folded zigzag and an annular frame 32 that holds the outer periphery of the filter body 31, and rotates. A horizontal rotation shaft 33 is provided at the center, and the rotation shaft 33 is rotatably supported by the tops of the

shaft support columns

10, 10, so that a part of the circumferential direction is submerged in the water tank 4. It is arranged in a vertical posture so that the lowermost part is submerged, and the water is sucked up to contain moisture. Further, the humidifying filter 3 is configured to be able to be inserted into and removed from the insertion portion 1c from the radial direction together with the water storage portion 4b of the water tank 4 while being supported by the

shaft support portions

10, 10.

The humidifying filter 3 is provided with a submerged portion in which the filter main body 31 is submerged by water that has entered the inside of the frame body 32 and a non-submerged portion that is not submerged in the circumferential direction.

The filter main body 31 is formed by cutting a part in the circumferential direction of the outer peripheral portion of a disc-shaped filter material having an appropriate thickness or punching a rectangular filter material into a desired shape, and the shape in front view is roughly D-shaped.

The humidifying filter 3 is configured such that the filter main body 31 is in a non-water-immersed state when the center in the circumferential direction of the non-water-immersed part is stopped vertically. Since the non-water-immersed filter body 31 does not absorb the water in the water tank 4, the filter body 31 is dried, and moisture absorption of the air passing through the filter body 31 is suppressed.

The frame body 32 is made of a synthetic resin and has an annular shape along the outer peripheral surface of the water-immersed portion of the filter main body 31. In addition, the frame body 32 is configured such that it can be easily assembled and dismantled manually by a builder or user. For this reason, the manufacturing worker or user can manually assemble the frame body. The filter body 31 can be easily attached to or detached from the 32.

At the rotation center of the humidifying filter 3, a cylindrical rotation shaft 33 that is orthogonal to the side surface of the filter body 31 is provided. Since the humidification filter 3 is arranged in a vertical posture so that a part of the circumferential direction can be submerged in the water tank 4, the rotary shaft 33 is arranged in a horizontal posture.

The rotary shaft 33 is rotatably supported on the tops of the

shaft column portions

10 and 10 extending upward from the side walls that are spaced apart from each other and spaced apart from the water storage portion 4b. As a result, the humidifying filter 3 supports the rotary shaft 33. It is supported at the center so as to be rotatable in the circumferential direction.

The humidifying filter 3 has a filter body 31 mounted in a frame 32, and the non-immersed part is heavier than the soaked part. Similarly, even when the filter main body 31 of the submerged part contains moisture, the non-submerged part is heavier than the submerged part.

A reed switch 20 is disposed on one side wall of the water tank 4, and a magnet 21 is disposed on one side of the humidifying filter 3. For convenience of detecting the approach / separation of the magnet 21 by the reed switch 20, the user can It is necessary to attach the humidification filter 3 in a state where the one surface on which the three magnets 21 are arranged faces one side wall of the water tank 4.

The magnet 21 is fixed to one side surface of the frame 32, and rotates and moves in a circular orbit along with the rotation of the humidifying filter 3. Specifically, the magnet 21 is arranged on the non-immersed part side on the imaginary line connecting the rotation center of the filter body 31 and the center in the circumferential direction of the non-immersed part. For this reason, when the magnet 21 is located in the vertical (lowermost part) of the humidification filter 3, the center in the circumferential direction of the non-immersed part is also arranged vertically.

When the magnet 21 approaches the reed switch 20, the reed switch 20 is turned on, and when separated, it is turned off. As a result, the reed switch 20 functions as a detector that detects the approach / separation of the magnet 21 with respect to the reed switch 20.

When the magnet 21 is arranged at the center in the circumferential direction of the switch-on region, the magnet 21 and thus the center in the circumferential direction of the non-water-immersed part are arranged vertically (lowermost part). In this state, the filter body 31 is not submerged. On the other hand, when the magnet 21 is greatly deviated from the center in the circumferential direction of the switch-on region, at least a part of the submerged portion is submerged and the filter main body 31 is submerged.

When the air is not humidified (during non-humidifying operation), it is necessary to stop the rotation of the humidifying filter 3 in a state where the filter body 31 is not submerged. Therefore, in order to measure the timing for stopping the rotation, the reed switch 20 and the magnet 21 are used. Is used, and the reed switch 20 is turned on and the rotation of the humidifying filter 3 is stopped when the center in the circumferential direction of the non-immersed part reaches the vertical (lowermost part).

The rotation drive mechanism 9 includes a roller 91 that contacts the outer peripheral surface of the frame 32 and rotates the humidification filter 3, and an electric motor 92 that is linked to the roller 91. Although the filter main body 31 is not disk-shaped, the frame body 32 is annular, so that the roller 91 can contact the outer peripheral surface of the frame body 32 to rotate the humidification filter 3.

The position where the roller 91 contacts the outer peripheral surface of the frame 32 is a position slightly separated in the circumferential direction opposite to the insertion portion 1c from the uppermost position of the outer peripheral surface of the frame 32, in other words, from the uppermost position. Is also the lower position.

The roller 91 is disposed so as to come into contact with a portion that is separated from the uppermost position of the humidifying filter 3 in the circumferential direction, and the rotation shaft 33 and the rotation center of the roller 91 are disposed in parallel to each other.
For this reason, when the roller 91 is rotated by the operation of the electric motor 92, the humidifying filter 3 rotates clockwise with the rotation of the roller 91. That is, the rotation drive mechanism 9 rotates the humidification filter 3 in the circumferential direction.

When performing maintenance such as water scale of the humidifying filter 3 and cleaning of the water tank 4, the humidifying filter 3 can be taken out from the insertion part 1 c of the housing 1 together with the water tank 4 in a state where the humidifying filter 3 is attached to the

shaft column parts

10, 10 of the water tank 4. It is a form.

The humidifying filter 3 taken out from the housing 1 is removed from the water tank 4, and the humidifying filter 3 and the water tank 4 alone are removed from the humidifying filter 3 and the water tank 4 to remove dirt and dust attached thereto. Perform cleaning maintenance.

When the maintenance is completed, the humidifying filter 3 is attached to the

shaft support portions

10 and 10 of the water tank 4 again. The form at this time is a state where the non-water-immersed part of the humidifying filter 3 is submerged in the water of the water tank 4, that is, the non-water-immersed part of the humidifying filter 3 is heavier than the water-immersed part. In this way, the humidifying filter 3 is rotated by its own weight, and the non-immersed part is vertical and is immersed in the water of the water tank 4.

When the non-immersed part of the humidifying filter 3 is vertically installed in the water tank 4 and is inserted into the housing 1 from the insertion part 1c, the peripheral surface of the roller 91 comes into contact with the outer peripheral surface of the humidifying filter 3, and the operation starts. Is possible.

In addition, between the blower outlet 14 and the air blower 8, the ion generator 22 which generate | occur | produces positive / negative ion simultaneously or individually is arrange | positioned. When the ion generator 22 is driven, ions are released from the ion generator 22 into the air that is directed from the fan 81 toward the air outlet 14, and the purified air and the humidified air contain the ions and are then supplied to the air outlet. 14 is blown into the room.

FIG. 3 is a perspective view showing an example of the water supply tank 5. The water supply tank 5 includes a tank body 5 a and a cap 50. The tank main body 5a is configured by a hollow member such that a generally flat box is vertically set, and water is stored therein. A cylindrical water inlet 5b (see FIG. 12) protrudes from the lower surface of the tank body 5a, and when the amount of water inside the tank body 5a decreases, the tank body 5a enters the tank body 5a from the water inlet 5b. Water is poured from a water supply etc. and replenished. A male screw 5c is formed on the outer peripheral surface of the water injection port 5b, and is configured to be screwed into a female screw 50a formed on the inner peripheral surface of the cap 50 (see FIG. 12).

As will be described later, the cap 50 is provided with a liquid outlet 51 and a valve body 60, and the valve body 60 has a predetermined direction (when the cap 50 is attached to the water inlet 5 b in order to close the liquid outlet 51. It is urged toward the outside of the water supply tank 5 (see FIG. 12). The water supply tank 5 is attached to the water supply part 4a of the water tank 4 with the cap 50 attached to the water injection port 5b. When the water supply tank 5 is attached to the water supply unit 4a, the valve body 60 is pushed upward to open the liquid outlet 51, so that the water in the water supply tank 5 flows out to the outside through the liquid outlet 51, and the water supply unit 4a. Is supplied with water. The configuration of the valve body 60 provided on the cap 50 will be described in detail later.

A transparent or translucent slit 5d is formed on one side of the tank body 5a so that the user can check the amount of water inside the tank body 5a from the outside. A handle 5e that is rotatably supported by a horizontal shaft is provided above the tank body 5a. The handle 5e is accommodated in a horizontal posture when the water supply tank 5 is attached to the water supply unit 4a, and is used when the water supply tank 5 is taken out from the water supply unit 4a. When the water supply tank 5 is transported, the handle 5e is returned to the vertical posture as shown in FIG.

When attaching the accommodating part 71 of the ion cartridge 70 to the leg part 72, the engaging hole 714 on the accommodating part 71 side and the engaging protrusion 726 a on the leg part 72 side are aligned, and the accommodating part 71 is moved to the leg part 72 side. , The engagement protrusions 726a on the leg portion 72 side are engaged with the engagement holes 714 on the accommodation portion 71 side, and the attachment is completed.

When the accommodating part 71 is attached to the leg part 72, the space (henceforth the accommodating space 700) divided by the side wall 711 and the partition plate 713 of the accommodating part 71, and the partition plate 723 of the leg part 72 is formed. The antibacterial agent is accommodated in the accommodation space 700. The example shown in FIG. 5 shows a state in which a large number of antibacterial agents molded in a columnar shape are accommodated.

In addition, it is preferable that the storage space 700 has a volume that is approximately twice the total volume of the antibacterial agent to be stored. In this case, since there is a space above the contained antibacterial agent, there is room for the antibacterial agent to move, and the antibacterial agent is efficiently stirred by the liquid and air (see FIG. 14) flowing through the inside of the ion cartridge 70. can do.

Further, eight outer communication holes 715, 715,..., 715 formed at equal intervals in the circumferential direction are provided on the outer peripheral surface at the upper end of the side wall 711 of the accommodating portion 71. Further, the partition plate 713 is also provided with a plurality of concentric circular inner communication holes 716 as viewed from above. The outer communication hole 715 and the inner communication hole 716 are holes that allow the accommodation space 700 and the space outside the ion cartridge 70 to communicate with each other.

Hereinafter, usage examples of the ion cartridge 70 will be described. 12 is a cross-sectional view showing a state when the water supply tank 5 is attached and detached, and FIG. 13 is a cross-sectional view showing a state when the water supply tank 5 is mounted. 12 and 13 show a state where the ion cartridge 70 is attached to the cap 50.

The cap 50 of the water supply tank 5 is provided with a liquid outlet 51 concentrically with the cylinder axis of the cap 50 and a valve body 60 supported so that the operation direction thereof coincides with the cylinder axis. The valve body 60 includes a columnar base portion 61, a flange portion 62 formed at the lower end of the base portion 61, and a valve portion 63 attached to the upper side of the base portion 61 and formed in a downward spherical shape (circular arc shape). Composed.

The base 61 of the valve body 60 is held by a through hole 55a inside the cylindrical portion 55 formed concentrically with the cylinder axis of the cap 50 so as to be movable in the vertical direction. Between the flange portion 62 of the valve body 60 and the lower surface of the cylindrical portion 55, the valve body 60 is urged downward to press the valve portion 63 against the liquid outlet 51 and close the liquid outlet 51. A spring 65 is arranged. A valve seat is formed at the upper opening edge portion of the liquid outlet 51, and the valve seat is configured to abut against the valve portion 63 when the water supply tank 5 is not attached and to close the liquid outlet 51. The water supply tank 5 is attached to and detached from the water supply part 4a of the water tank 4 in an oblique posture as shown in FIG.

A columnar convex portion 40 is formed at the bottom of the water supply portion 4a. When the water supply tank 5 is attached to the water supply part 4a, the convex part 40 is positioned so that the upper contact surface 40a of the convex part 40 comes into contact with the lower part of the valve body, and stands on the bottom of the water supply part 4a. Has been.
Further, the water supply tank 5 is configured to be supported by the water supply unit 4a so as to be in a vertical posture when mounted. For this reason, when the water supply tank 5 is attached to the water supply part 4a, the flange part 62 of the valve body 60 provided in the cap 50 contacts the contact surface 40a of the upper part of the convex part 40, and is pushed up in the vertical direction. It is configured. At this time, the valve part 63 of the valve body 60 is separated from the valve seat formed at the upper opening edge of the liquid outlet 51, and the liquid outlet 51 is opened.
The liquid stored in the water supply tank 5 flows out from the opened liquid outlet 51 and flows down to the water supply part 4 a of the water tank 4 through the gap between the inner peripheral surface of the liquid outlet 51 and the outer peripheral surface of the cylindrical part 55. To do.

In this embodiment, since the ion cartridge 70 is attached to the upper side of the liquid outlet 51, the liquid flowing out from the water supply tank 5 passes through the inside of the ion cartridge 70 and flows out through the liquid outlet 51. Further, as the liquid flows out from the water supply tank 5, air flows from the outside of the water supply tank 5. The air flowing in at this time is introduced from the liquid outlet 51, passes through the inside of the ion cartridge 70, and flows into the liquid tank 5.

FIG. 14 is a schematic diagram showing the flow paths of liquid and air. In FIG. 14, the flow path of the liquid is indicated by a black arrow, and the air particle diameter path is indicated by a white arrow. When the water supply tank 5 is attached to the water supply part 4 a of the water tank 4, the liquid outlet 51 is opened as shown in FIG. 14, and the liquid inside the water supply tank 5 flows out through the liquid outlet 51. . At this time, the liquid is taken in from the outside of the ion cartridge 70 through the outer communication hole 715 and the inner communication hole 716 provided in the accommodating part 71 of the ion cartridge 70 and the communication hole 724 provided in the side wall 721 of the leg part 72. Since the liquid taken into the container 71 dissolves the antibacterial component from the antibacterial agent stored in the storage space 700, the liquid surrounded by the side wall 721 of the leg part 72 contains the antibacterial component well. Flows through the communication hole 725 of the partition plate 723. The liquid well containing the antibacterial component mixes with the liquid flowing in from the communication hole 724 provided on the lower side of the leg portion 72, and flows down to the outside of the water supply tank 5 (the water supply portion 4 a of the water tank 4) through the liquid outlet 51.

On the other hand, the air introduced from the outside of the water supply tank 5 flows into the space in the leg portion 72 through the liquid outlet 51. The air that has flowed into the space in the leg portion 72 flows into the space in the housing portion 71 (the housing space 700) from the communication hole 725 of the partition plate 723. Since a large number of antibacterial agents having appropriate sizes are stored in the storage space 700, the antibacterial agents are appropriately disturbed and collided when air flows in and flows through the communication holes 725 of the partition plate 723. be able to. The air that has flowed into the accommodating portion 71 is discharged to the inside of the water supply tank 5 (outside of the ion cartridge 70) through the outer communication hole 715 and the inner communication hole 716 above the accommodating portion 71.

As described above, in the present embodiment, since the antibacterial component contained in the antibacterial agent can be dissolved using the flow of liquid and air introduced when water is supplied from the water supply tank 5, the antibacterial component is simply put in the tank. The effect of high elution efficiency is obtained compared to the case where the agent is added.
For example, when 5 g of pellet-shaped antibacterial agent having a length of 3.0 mm and a diameter of 2.5 mm is charged into the tank, the concentration of the antibacterial component after 6 hours was 15 ppb, whereas this embodiment When the same experiment was performed using the ion cartridge 70 according to the above, the concentration of the antibacterial component could be increased to about 30 to 40 ppb.

In addition, although the form which applied this invention to the air cleaner with a humidification function was demonstrated, it is needless to say that it is applicable also to the water supply apparatus utilized with a humidification apparatus. Moreover, this invention is applicable also to water supply apparatuses, such as a water server, which do not have a humidification function and an air purifying function. In this case, the solid substance contained in the ion cartridge 70 does not necessarily need to be an antibacterial agent, and may be other substances. For example, when activated carbon is accommodated in the ion cartridge 70, it goes without saying that the deodorizing / purifying effect is improved by the disturbance and collision inside the ion cartridge 70.
