[Problems with background technology]

By the way, humidifiers include the above-mentioned ultrasonic type, centrifugal spray type, pressure spray type, steam type, and vaporization type. The spray method directly sprays water as small particles, so dissolved salts such as calcium, magnesium, and silica contained in the water are also sprayed into the air along with the mist, and the water in the sprayed mist evaporates. If this happens, the dissolved salts will solidify and float around the room, damaging furniture, walls,
It adheres to glass surfaces in the form of white powder, spoiling its aesthetic appearance, and cleaning it is extremely troublesome.

Further, in ultrasonic or steam type humidifiers, when used for a long time, the above-mentioned salts adhere to the evaporating dish of the ultrasonic vibrator 3, resulting in a problem that the performance deteriorates and the life of the humidifier is shortened.

Therefore, a method has been adopted in which raw water is passed through a separate water purifier equipped with an ion exchange resin to make it pure water, and then the pure water is poured into a water tank, but this method requires two water supply operations. This increases the effort and time required for water supply work.

Furthermore, in recent years, a structure has been proposed in which an ion exchange resin is disposed inside the water tank or the main body, and water is supplied to the atomization tank via the ion exchange resin. Furthermore, when ion exchange resin is disposed in a water tank, in order to ensure a certain capacity of the water tank, it is necessary to increase the capacity of the water tank for the ion exchange resin. Furthermore, when disposing it inside the main body, there is often no space for the arrangement in the existing main body, so it is necessary to manufacture a new main body, which inevitably increases the cost considerably.

By the way, the amount of water that can be ion-exchanged is approximately proportional to the amount of ion-exchange resin, so it is desirable to set the amount of ion-exchange resin depending on the conditions of use. With the method of arranging , the amount cannot be set freely.

[Purpose of invention]

The present invention is an attempt to solve the above-mentioned problems, and it is possible to easily install an ion exchange resin in an existing humidifier, and also to easily replace the ion exchange resin. Furthermore, it is an object of the present invention to enable the amount of ion exchange resin to be freely set depending on usage conditions and the like.

[Summary of the idea]

The present invention includes a main body having an atomizing section and a water tank detachably mounted on the main body, the water tank is provided with a water supply port that is opened and closed by a valve, and the main body has a valve for the water tank. In the humidifier, the humidifier is provided with a contact part that opens by pushing the water tank, and an opening that faces the water supply port of the water tank and communicates the atomizing part and the water tank, by pushing the valve of the water tank. The ion exchange unit has an opening that opens, an inlet that faces the water supply port of the water tank, and an outlet that faces the opening of the main body, and the ion exchange unit houses an ion exchange resin therein. It is removably installed between the water tank and the water tank.

Note that this humidifier has the same structure as that shown in FIGS. 8 to 10 above, except for the ion exchange unit 31, so corresponding parts are designated by the same reference numerals and a description thereof will be omitted.

The ion exchange unit 31 is formed into a substantially rectangular box shape whose planar shape is the same as the lower surface shape of the water tank 13. Inside the ion exchange unit 31, a cylindrical body 32 extending vertically is provided at a position corresponding to the water supply port 14 of the water tank 13 and the opening 23 of the main body 1. The interior of this cylindrical body 32 is divided by a horizontal partition wall 33 into an upper primary water supply chamber 34 and a lower secondary water supply chamber 35.

The upper surface of the cylindrical body 32 is opened to form an inlet 36.
An annular seal packing 37 made of an elastic material is attached to the periphery of the inlet 36. Further, a protrusion 38 is formed to protrude upward from the center of the horizontal partition wall 33 and serve as a contact portion for the valve rod 20 of the water tank 13. That is, the configuration of the inlet 36 is the same as the configuration of the opening 23 of the main body 1.

On the other hand, an outlet 39 is formed on the lower surface of the cylindrical body 32, and the structure of the outlet 39 is as follows.
The configuration is the same as that of the water supply port 14 of the water tank 13 described above. That is, an outlet pipe 40 is vertically installed at the lower part of the outlet port 39, and a valve 41 is installed in this outlet pipe 40.
A water supply cap 42 is removably screwed onto the water supply cap 42.

Further, inside the ion exchange unit 31, an air exchange chamber 44 on one side and an ion exchange chamber 45 on the other side are defined by a vertical partition wall 43 intersecting with the cylindrical body 32. The ion exchange chamber 45 is formed into a substantially U-shape in plan by a partition wall 46 orthogonal to the cylindrical body 32, and the inside thereof is filled with an ion exchange resin 47.

And the primary water supply chamber 34 and the air exchange chamber 44
means the upper air exchange port 4 formed in the cylindrical body 32.
The secondary water supply chamber 35 and the air exchange chamber 44 are communicated through a lower air exchange port 49 formed in the cylindrical body 32 . In addition, above 1
The next water supply chamber 34 and the ion exchange chamber 45 are the cylindrical body 3
The secondary water supply chamber 35 and the ion exchange chamber 45 are in communication with each other through an exchange chamber inlet 50 formed in the cylindrical body 32, and the ion exchange chamber 45 is located at a position facing the exchange chamber inlet 50 of the cylindrical body 32 with a partition wall 46 in between. They are communicated by an exchange chamber outlet 51 formed therein. The upper air exchange port 48 is formed at a height that is located above the lower surface of the water supply cap 16 of the water tank 13 when the water tank 13 is placed on the ion exchange unit 31, and the upper air exchange port 48 is formed at a height that is located above the lower surface of the water supply cap 16 of the water tank 13. The inlet 50 is formed at a height below the lower surface of the water supply cap 16.

Then, when the ion exchange unit 31 is placed on the main body 1, the water supply cap 42 of the ion exchange unit 31 is fitted into the opening 23 of the main body 1 in a fluid-tight manner, and the protrusion 24 of the main body 1 is connected to the water supply cap 42. The valve 41 of the cap 42 is opened. That is, the support frame 52
The valve rod 54 supported by the coil spring 53 is pushed up, and the valve body 55 is pushed up into the valve hole 56.
Open the secondary water supply chamber 3 of the ion exchange unit 31.
5 and an atomization tank 2 serving as an atomization section of the main body 1 are communicated with each other.

Next, the water tank 13 is transferred to the ion exchange unit 3.
1, the water supply cap 16 of the water tank 13 is liquid-tightly fitted into the inlet 36 of the ion exchange unit 31, and the ion exchange unit 3
The protrusion 38 of No. 1 opens the valve 17 of the water supply cap 16, and the water tank 13 and the No. 1 of the ion exchange unit 31 open.
The next water supply chamber 34 is communicated.

Water then flows from the water tank 13 through its water supply cap 16 into the primary water supply chamber 34, and then through the exchange chamber inlet 50 into the ion exchange chamber 4.
5, where salts that cause white powder are removed by an ion exchange resin 47. The ion-exchanged water flows into the secondary water supply chamber 35 through the exchange chamber outlet 51, and then flows into the atomization tank 2 of the main body 1 through the water supply cap 42 of the ion exchange unit 31. . Note that at this time, the water level in the atomization tank 2 is kept constant by the water supply cap 42.

On the other hand, when the water level in the atomization tank 2 decreases as the humidifier operates, replacement air flows into the secondary water supply chamber 35 via the water supply cap 42 of the ion exchange unit 31, and then , lower air displacement port 49
It flows into the air exchange chamber 44 through the upper air exchange port 48, and further flows into the primary water supply chamber 34 through the upper air exchange port 48, and is supplied into the water tank 13 from the water supply cap 16 of the water tank 13.

According to the above configuration, ion-exchanged water can be supplied to the atomization tank 2 of the main body 1 simply by installing the detachable ion exchange unit 31 between the main body 1 and the water tank 13. Moreover, since water need only be supplied to the water tank 13, no effort is required for water supply work.

Further, since the ion exchange unit 31 is detachable, when the capacity of the ion exchange resin decreases, it is sufficient to replace it with a new ion exchange unit 31.

Furthermore, since it can be attached to existing humidifiers without an ion exchange device, it can also be used as a service part.

Further, since the planar shape of the ion exchange unit 31 is made the same as the lower surface shape of the water tank 13, the appearance is not spoiled.

Furthermore, by changing the height of the ion exchange unit 31, the amount of ion exchange resin 47 stored therein can be set arbitrarily, so the lifespan of the ion exchange unit 31 itself can be adjusted arbitrarily depending on the usage conditions. Can be set.

In addition, in the above embodiment, the ion exchange unit 3
Although a configuration has been described in which the water supply cap 42 having a valve 41 is detachably attached to the outlet 39 of the water outlet 1, the valve 41 is not necessarily necessary, and the outlet pipe 40 is connected to the water supply cap 42 without attaching the water supply cap 42. It may be formed into approximately the same shape as.

Next, another embodiment of the present invention will be described with reference to FIGS. 5 to 7.

In this embodiment, a substantially U-shaped pipe body 57 is provided in the ion exchange unit 31, with one end fluid-tightly connected to the exchange chamber inlet 50 and the other end fluid-tightly connected to the exchange chamber outlet 51. It is detachable. The inside of this pipe body 57 serves as an ion exchange chamber 45, and an ion exchange resin 4 is placed therein.
7 is filled. Further, in this embodiment, the partition wall 46 in the previous embodiment is not required and is therefore not provided. Further, the lower surface of the ion exchange unit 31 is opened so that the pipe body 57 can be attached and detached.

According to this configuration, when the capacity of the ion exchange resin 47 decreases, it is only necessary to replace the pipe body 57.

In addition, in implementation, in addition to providing protrusions 24 and 38 on the valves 17 and 41 of the water tank 13 and ion exchange unit 31 with which the valve rods 20 and 54 come into contact, the lower ends of the valve rods 20 and 54 are lengthened. Its lower end is the water tank 13 and ion exchange unit 31.
When mounted, it may come into direct contact with the partition wall 33, the bottom wall of the atomization tank 2, etc.

[Effect of idea]
