Description

  The present invention relates to an air cleaner having a humidifying function and a dehumidifying function.

Conventionally, air cleaners having both a dehumidifying function and a humidifying function are disclosed in Patent Documents 1 to 6 and the like.
The water used for humidification must be sterilized like tap water and free of harmful germs, molds and other harmful substances. However, in the case of an air purifier that has both a dehumidifying function and a humidifying function, the condensed water generated by dehumidification is mixed with various floating substances in the air, and if left as it is, germs and fungi grow, and this occurs due to dehumidification. The condensed water cannot be used as it is for humidifying the room air.

In the above-described prior art air purifier, the condensed water generated by dehumidification is boiled and evaporated by a heater to sterilize and vaporize water, or the condensed water generated by monitoring the passage of time after the dehumidifying operation is discarded. It is the structure which makes it notify so that the water may not be used.
Alternatively, a tank for water supplied to the humidifying operation and a tank for draining the water condensed by the dehumidifying operation are provided, respectively, and the condensed water generated by the dehumidifying operation is separated so as not to be mixed with the humidifying water, or In addition, both dehumidification and humidification operations can be performed by purifying the condensed water resulting from dehumidification with a filter or water purification means.

Japanese Utility Model Publication No. 63-198934 Japanese Utility Model Publication No. 61-285327 JP-A-10-259933 JP 2008-290067 A JP 2008-256285 A JP 2009-145042 A

  By the way, in the case of the means for boiling and evaporating water with a conventional heater, the temperature of the steam blown into the room is high, and there is a problem in safety. In addition, since the condensed water is stored in the tank until it is used for humidification, the germs may grow badly depending on the environment such as high temperature and humidity at the time of use and the time for which it is left. In such a case, it is conceivable that the sterilization cannot be completely performed only by boiling for a short time.

Also, in the method of separating the tank so that the condensed water generated by dehumidification is not mixed into the humidifying water by installing two tanks for storing dehumidified condensed water and for tap water for humidification, two tanks with large capacities are used. Therefore, there is a problem that the air cleaner is inevitably enlarged.
On the other hand, in the method of purifying the dew condensation water stored in the water tank of Patent Document 6 with the water purification means, the purified water and the unpurified water are mixed in the same water tank. There is a problem that water that is not used is used for humidification.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a small air cleaner that solves the sanitary problem of water for dehumidification / humidification and can save labor in maintenance work of water supply / drainage for dehumidification / humidification water.

  In order to achieve the above object, an air cleaner according to the present invention includes a fan for sucking in external air, and a purification filter unit provided on the upstream side of the fan for purifying air sucked by the fan. A vaporization filter unit disposed between the purification filter unit and the fan for humidifying the air, a water supply tank for storing water to be supplied to the vaporization filter unit, the purification filter unit, and the fan And a dehumidifying unit that dehumidifies the air, and includes a filtration unit that filters condensed water discharged from a condenser of the dehumidifying unit during a dehumidifying operation, and the condensed water is After being filtered by the filtration unit, it is collected in the water supply tank and used for the humidifying operation.

  ADVANTAGE OF THE INVENTION According to this invention, the small air cleaner which can labor-saving the maintenance operation | work of the supply / drainage of dehumidification / humidification water can be obtained.

It is a perspective view showing an air cleaner of an embodiment concerning the present invention. It is a disassembled perspective view of the air cleaner of embodiment. It is the perspective view which looked at the water tank of embodiment from diagonally upward. FIG. 4 is a cross-sectional view taken along the line P-P of FIG. 3 when a condensed water filtration unit is installed in the water collection hole of the water tank of the embodiment and a water purification unit is installed in a water supply protrusion of the water tank lid. It is an expanded sectional view of the filtration unit of an embodiment. It is a perspective view which shows the water purification unit of embodiment. It is the QQ sectional view taken on the line of the water purification unit of FIG. 6 of embodiment. It is the partial cross section figure which looked at the lower part of the condenser shown in FIG. 2 of embodiment from the front.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a perspective view showing an air cleaner 1 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the air cleaner 1 according to the embodiment.
The air cleaner 1 shown in FIG. 1 is sucked by a centrifugal fan 7a (see FIG. 2) that sucks indoor air through a clearance c between the front panel 4 and the front housing case 3, and the centrifugal fan 7a. A filter unit 5 (see FIG. 2) is provided for filtering indoor air to clean it by collecting dust and deodorizing. The centrifugal fan 7a is driven by the fan motor 7.

  As shown in FIG. 2, the air purifier 1 has a water tank 13 in which water for humidification is stored, and a filter as a humidifying function for humidifying a dry indoor air whose humidity is equal to or lower than a predetermined value. A vaporizing filter unit 15 is provided which is made to pass air purified through the unit 5 and humidifies with water pumped up from the water tank 13.

In addition, the air purifier 1 is used for dehumidification as a dehumidifying function for performing a dehumidifying mode for dehumidifying indoor air whose humidity is equal to or higher than a predetermined value, and passing the purified air through the filter unit 5 to absorb moisture and dehumidify it. Of the desiccant rotor 9, the heater 33 for heating the air that vaporizes the absorbed moisture through the desiccant rotor 9, and the air containing the moisture absorbed and vaporized from the desiccant rotor 9 and the lattice portion 11 b 1 (see FIG. 2). And a condenser 11 for condensing the water by letting the lower part of the condenser 11 shown in FIG. FIG. 8 shows a case where a filtration unit 14 described later is provided at the outlet of the condensed water discharge hole (condensed water discharging means) 11c1 of the condenser 11 (modified example of this embodiment).
It should be noted that humidification and dehumidification by the air cleaner 1 are performed according to the humidity of the indoor air, and of course, humidification and dehumidification are not performed when the humidity is appropriate.

  In addition, as shown in FIG. 2, the air purifier 1 has a shape surrounding the centrifugal fan 7a in order to exhaust the air that has been sucked and cleaned by the centrifugal fan 7a and humidified and dehumidified again to the outside. And a spiral fan casing 8 formed in a shape in which the gap with the outer periphery of the centrifugal fan 7a increases toward the upper discharge port 2o.

<Humidification mode of air cleaner 1>
In the humidification mode by the humidification function of the air purifier 1, the water in the water tank 13 is sucked up by a pump (not shown) provided inside the main body, and humidified water is supplied to the vaporizing filter unit 15 to contain moisture. Then, the air cleaned by the filter unit 5 is passed through the vaporizing filter unit 15 containing moisture to evaporate moisture from the vaporizing filter 6 and humidify. The humidified air is discharged through the fan casing 8 to the outlet 2o. From the room.
The vaporization filter unit 15 and the water tank 13 are detachable by the user, and maintenance such as cleaning and water supply to the water tank 13 can be performed.

<Dehumidification mode of the air cleaner 1>
In the dehumidifying mode by the dehumidifying function of the air purifier 1, the room air cleaned by the filter unit 5 was blown to the rotating desiccant rotor 9, and moisture of the air blown to the desiccant rotor 9 was absorbed to dehumidify the air. Thereafter, the dehumidified air is returned to the room through the fan casing 8 from the outlet 2o.

  Hot air heated by the heater 33 is blown to the desiccant rotor 9 that has absorbed moisture in the room air, and the room air is regenerated (dried) so that it can be dehumidified again. Air (hot air) containing moisture absorbed from the desiccant rotor 9 generated during the regeneration flows from the upper part of the lattice part 11b1 of the condenser 11 to the lower part by the air in the machine from the outside of the lattice part 11b1. Cool to lower saturation humidity and condense moisture to remove moisture from the air. The water thus removed drops downward from the condensed water discharge hole 11c1 (see FIG. 8) at the outlet of the water provided at the lowermost part of the condenser 11, and the water tank lid 13b, which will be described later, is received by the water tank 13. Is collected in the water tank 13 from the water collection hole (collection means) 13b1 of the central collection port.

That is, the water tank 13 is a humidifying water replenishment tank when the humidifying function is used, and functions as a condensed water recovery tank generated by dehumidification when the dehumidifying function is used. It also functions as a recovery tank. That is, in this air cleaner 1, the condensed water produced by dehumidification when using the dehumidifying function is used as humidifying water when using the humidifying function.
In order to avoid the increase in equipment size due to the provision of two tanks: a replenishment tank for humidification water when using the conventional humidification function and a recovery tank for condensed water generated by dehumidification when using the dehumidification function. This is a water tank 13.

<Water tank 13>
FIG. 3 is a perspective view of the water tank 13 as viewed obliquely from above.
As described above, the water tank 13 shown in FIG. 3 contains the condensed water dehumidified from the indoor air in the dehumidifying mode in the air purifier 1 and humidified to humidify the air purified by the filter unit 5. In mode, store until condensed water is used.
In addition, when dehumidification is not performed with the air cleaner 1 at the time of shifting to the humidification mode, the water for the humidification mode in the water tank 13 is insufficient. In this case, the water tank 13 is pulled out to the outside of the air cleaner 1 by the user, and water is supplied from the water supply hole 13b2.

The water tank 13 includes a water tank box 13a in which condensed or supplied water is stored, and a water tank lid 13b that covers the water tank box 13a. The water tank lid 13b has a water collecting hole 13b1 at the center thereof for collecting water condensed in the lattice portion 11b1 of the condenser 11 and dripping from the condensed water discharge hole 11c1 (see FIG. 8) into the water tank box 13a. Is formed. The water tank lid 13b is inclined downward so that the water collecting hole 13b1 is the lowest.
Further, the water tank lid 13b is provided with a water supply hole 13b2 for allowing the user to supply water when the water in the water tank box 13a is insufficient or has disappeared.

Further, the water tank lid 13b has a water supply protrusion 13b3 having a suction hole 13b31 for sucking the water in the water tank 13 to the vaporization filter unit 15 by a pump (not shown) provided in the main body, and a vaporization. A circulation projection 13b4 having a return hole 13b41 for returning water overflowing from the filter unit 15 into the water tank 13 is formed.
The water tank lid 13b is formed so that the suction hole 13b31 of the water supply projection 13b3 of the water tank lid 13b is continuous with the lower part of the water tank box 13a so that the water in the lower part of the water tank box 13a can be sucked up. (See FIG. 4).

FIG. 4 is a cross-sectional view taken along the line P-P in FIG. 3 when the condensed water filtration unit 14 is installed in the water collection hole 13b1 of the water tank 13 and the water purification unit 16 is installed in the water supply projection 13b3 of the water tank lid 13b. FIG. 5 is an enlarged cross-sectional view of the filtration unit 14.
Condensed water discharged from the condensed water discharge hole 11 c 1 (see FIG. 8) of the condenser 11 shown in FIG. 2 is dropped into the water tank lid 13 b of the water tank 13 and passes through the water collection hole 13 b 1 of the water tank 13. Enters and is stored.
The condensed water supplied from the condenser 11 contains foreign substances, germs, molds and the like contained in the indoor air.
Then, the condensed water is discharged from the condensed water discharge hole 11c1 of the condenser 11 through the filtration unit 14 for filtering the condensed water from the condenser 11 to remove foreign substances, germs and the like, and the water collecting hole of the water tank 13 is collected. It is installed on the path while dropping through the water tank box 13a through 13b1, that is, at the outlet of the water collecting hole 13b1.

<Filtration unit 14>
The filtration unit 14 for filtering condensed water shown in FIG. 5 mainly includes a nonwoven fabric filter 14a for filtering out foreign substances in the condensed water with a woolen fabric, etc., and porous carbon for removing pigments and odors of condensed water by adsorption. Activated carbon 14b as an active ingredient, active ion granules 14c for sterilizing and sterilizing various bacteria and fungi by eluting active ions in condensed water, holding nonwoven filter 14d for holding active ion granules 14c, etc. These four layers are accommodated and provided in the inner case 14e. The eyes of the holding nonwoven fabric filter 14d need only be smaller than the particle size of the active ion granules 14c. Therefore, the holding nonwoven fabric filter 14d does not need to be a nonwoven fabric, and may be a resin mesh. Instead of disposing the activated carbon 14b on the upstream side and the active ion granules 14c on the downstream side, the active ion granules 14c may be disposed on the upstream side, and the activated carbon 14b may be disposed on the downstream side. When it takes time for the active ions to elute in water, it is preferable that the active ion granules 14c are arranged downstream or below the gravitational direction rather than the activated carbon 14b. Further, instead of separating the activated carbon 14b and the active ion granules 14c, the activated carbon 14b and the active ion granules 14c may be mixed.

The assembly of the filtration unit 14 is performed as follows.
First, as shown in FIG. 5, an appropriate amount of activated carbon 14b is put on one side of a cylindrical inner case 14e, and an activated carbon holding plate 14e1 with a water passage hole is fitted into the inner case 14e. 14a is disposed on the inner peripheral surface of the inner case 14e by bonding or the like. In addition, a predetermined amount of active ion granules 14c is placed on the other side of the inner case 14e, covered and held by a holding nonwoven filter 14d from the outside, and an ion granule / nonwoven filter holding plate 14e2 having a water passage hole is provided. Fits into the inner case 14e.

  Then, the outer pan 14f having a shape (for example, a cylinder with an upper portion opened and a lower portion closed) in which the cylindrical inner case 14e enters and contains water, the nonwoven fabric filter 14a, the activated carbon 14b, the active The inner case 14e accommodating the ion granules 14c and the like is covered and fitted from below, and the filtration unit 14 shown in FIG. 5 is completed.

A female screw 14em threaded on the upper inner peripheral surface of the inner case 14e of the completed filtration unit 14 is screwed onto a male thread 13bm threaded outside the water collecting hole 13b1 of the water tank lid 13b, as shown in FIG. Thus, the filtration unit 14 is attached to the water tank lid 13b.
Thus, the condensed water dropped and discharged from the condensed water discharge hole 11c1 of the condenser 11 into the outer pan 14f of the filtration unit 14 attached to the outlet of the water collection hole 13b1 of the water tank lid 13b is shown in FIG. As indicated by the arrow α13, it can be retained until it overflows from the upper end edge 14f1 of the outer pan.

Filtration of the condensed water condensed in the condenser 11 by the filtration unit 14 is performed as follows.
As shown in FIG. 5, the condensed water flowing from the condensed water discharge hole 11c1 of the condenser 11 to the water collecting hole 13b1 of the water tank 13 passes through the water collecting hole 13b1 to the inlet of the filtration unit 14 as indicated by an arrow α11 in FIG. Is dropped onto the non-woven fabric filter 14a installed in the tube, passes through the activated carbon 14b, the active ion granule 14c, and the holding non-woven fabric filter 14d, and then flows in the outer pan 14f as indicated by an arrow α12 in FIG. The condensed water that has entered the filtration unit 14 stays in the outer pan 14f until it overflows from the upper end edge 14f1 of the outer pan and falls into the water tank box 13a as indicated by an arrow α13 in FIG. Since the outer pan upper end edge 14f1 is above the nonwoven fabric filter 14a, the nonwoven fabric filter 14a, the activated carbon 14b, and the active ion granules 14c are immersed in the condensed water while the outer pan 14f is filled with condensed water. It will be. When it is preferable not to immerse the nonwoven fabric filter 14a in condensed water, the outer pan upper end edge 14f1 may be formed below the nonwoven fabric filter 14a, and when it is preferable not to immerse the activated carbon 14b in condensed water. The outer pan upper end edge 14f1 may be formed below the activated carbon 14b, and when it is preferable not to immerse the active ion granule 14c in condensed water, the outer pan upper end edge 14f1 is formed from the active ion granule 14c. May be formed on the lower side. However, when it takes time for the active ions to elute in water, it is preferable to form the upper end edge 14f1 of the outer pan above the active ion granules 14c. When it takes time to adsorb the pigment and odor of condensed water, it is preferable to form the upper end edge 14f1 of the outer pan above the activated carbon 14b. It is preferable that the detection water level of the water level detector in the water tank 13 for warning that the water tank 13 overflows is lower than the upper end edge 14f1 of the outer pan.

  By continuing the dehumidifying operation, while the outer pan 14f is filled with condensed water, that is, as time passes until it overflows as shown by an arrow α13 in FIG. 5, the condensed water is converted into activated carbon 14b and active ion granules 14c. In the condensed water, odor components and fine components contained in the condensed water are adsorbed on the activated carbon 14b, and more active ions are eluted in the condensed water staying from the active ion granules 14c. Is sterilized and sterilized, and the condensed water in the outer pan 14f is purified.

  More specifically, regarding the condensed water generated by the dehumidifying operation, not only the moisture in the air but also various foreign matters and odors contained in the air adhere to the desiccant rotor 9 together by the dehumidifying operation. The hot air heated by the heater 33 dissolves the adhering substances together with moisture into the condensed water condensed while flowing through the lattice portion 11b1 (see FIGS. 2 and 8) of the condenser 11. Therefore, conventionally, the condensate produced by the dehumidifying operation has to be discarded due to hygiene problems. When switching from the dehumidifying operation to the humidifying operation, the water accumulated in the water tank 13 must always be discarded by flushing even a little accumulated water. I needed it.

Conventionally, in drinking water, there is an example in which purification of water is put into practical use by simple filtration using activated carbon or the like as a water purifier.
However, in order to filter the condensed water generated by dehumidification in the air cleaner 1 and reuse it as humidifying water, not only the condensed water is filtered, but also various germs do not propagate even if left for a period of time in the stored state. It is essential that processing be added.
For example, in the case of tap water, not only is chlorine injected and sterilized in the water purification process, but when a user taps out the stored tap water, a certain amount or more of chlorine remains and germs remain. It is managed not to breed.

On the other hand, if the condensed water generated by dehumidification is rendered harmless by the filtration unit 14, various germs will not propagate in the water tank 13.
Therefore, the filtration unit 14 realizes a sterilization and sterilization effect by producing the same effect as chlorine of tap water by the active ions eluted from the active ion granules 14c. Here, as for the sterilization effect of the active ions in the condensed water, for example, if it is Ag ions, it has been confirmed that if there is an active ion concentration of about 0.1 mg / L or more, various bacteria can be killed.
Condensed water generated by dehumidification drops in the filtration unit 14 at a maximum rate of 4 to 5 cc / min, so that the condensed water that has been dripped stays in a small space in the outer pan 14f of the filtration unit 14 for a certain period of time. A large amount of active ions are eluted in the same condensed water to form a state in which the active ion concentration is increased to a high bactericidal power.

The germs contained in the newly dropped condensed water are once killed in the outer pan 14f of the filtration unit 14, and then overflow and drop into the water tank box 13a of the water tank 13, so that safe water Can be used for humidification.
Moreover, since the dripped condensed water stays inside the filtration unit 14 and is also exposed to the activated carbon 14b for a certain period of time, foreign substances and odors in the condensed water are also effectively adsorbed by the activated carbon 14b.
That is, conventionally, after the dehumidifying operation, it has always been troublesome to drain the condensed water generated by dehumidification in the water tank and to clean the water tank. By filtering and purifying with the filtration unit 14 before being collected in the water tank 13, the problem of hygiene of water (condensed water) can be solved, and the water can be reused for humidification operation. The handling can be improved.

  Here, the condensed water in the outer pan 14f is the condensed water produced by the subsequent dehumidification while the active ions eluted from the active ion granules 14c are kept in a high concentration state. Therefore, the active ions with high concentration always surround the germs contained in the condensed water that has been dripped, and are sterilized and sterilized. The active ion granule 14c elutes active ions as it passes through water, and gradually dissolves, so replenishment is required according to the amount of water passing through.

However, since the amount of condensed water passing through the filter unit 14 is substantially determined by the dehumidifying operation time of the air purifier 1, it is possible to continuously maintain the filtering capacity by replacing the filter unit 14 after a certain dehumidifying operation time. Is possible. That is, the user who uses the dehumidifying mode of the air purifier 1 can maintain the filtering ability by replacing the filtering unit 14 with a new one every predetermined period.
The filtration unit 14 is provided between the water tank box 13a through the path during which the condensed water is dripped into the water tank 13, that is, the condensed water discharge hole 11c1 of the condenser 11 and the water collection hole 13b1 of the water tank lid 13b. Since it is attached to the water tank lid 13b, the user can pull out the water tank 13 to the outside of the air purifier 1, remove the used filtration unit 14 from the water tank lid 13, and replace it with a new filtration unit 14. Replacement of the filtration unit 14 can be performed very easily.

<Water purification unit 16>
6 is a perspective view showing the water purification unit 16, and FIG. 7 is a cross-sectional view taken along the line Q-Q of the water purification unit 16 in FIG.
Similar to the filtration unit 14, as shown in FIG. 4, the water purification unit 16 containing the active ion granules 16c (see FIG. 7) is converted into a vaporization filter unit 15 by pumping water in the water tank 13 (not shown). Is provided on the water supply protrusion 13b3 (see FIG. 4) of the water tank lid 13b having a suction hole 13b31 for sucking it up.

A water purification unit 16 shown in FIG. 6 has a water purification unit lid in which active ion granules 16c are placed in a unit case 16a in which a water passage hole 16a1 is formed, as shown in FIG. 16b is assembled to the unit case 16a from the outside of the active ion granules 16c in the unit case 16a. It is preferable to install the water purification unit 16 so that the water passage hole 16a1 is disposed below the upper end edge 14f1 of the outer pan.
As shown in FIG. 4, the assembled water purification unit 16 has a screw n inserted through a screw-through hole 16a3 of an engagement protrusion 16a2 formed on the upper part of the unit case 16a, and a water supply protrusion 13b3 inside the water tank lid 13b. Is attached to the water supply protrusion 13b3 in the water tank lid 13b.

In this way, the water purification unit 16 attached to the water supply protrusion 13b3 in the water tank lid 13b is immersed in the condensed water stored in the water tank 13 to allow the condensed water to flow as shown by the arrows in FIG. The active ions are eluted from the active ion granules 16c into the condensed water in the water tank 13, and the condensed water in the water tank 13 is sterilized and sterilized.
For this reason, in the water (condensed water) in the water tank 13, if bacteria are injected from the outside exceeding the limit, miscellaneous bacteria will not propagate even if left to stand.
When the condensed water in the water tank 13 is sucked into the vaporization filter unit 15 by a pump (not shown), the condensed water in the water tank 13 passes through the water purification unit 16 as shown by the arrow in FIG. Then, it is sent to the vaporizing filter unit 15 through the suction hole 13b31 of the water supply projection 13b3 of the water tank lid 13b shown in FIG.

<Effect>
According to the above configuration, the condensed water obtained by dehumidification is filtered and purified by the filtration unit 14, and further purified by the water purification unit 16, so that the condensed water can be reused as it is for the humidification operation without being discarded.
Thereby, the maintenance work at the time of switching between dehumidification and humidification is eliminated, and the air cleaner 1 having good handleability can be obtained.
Further, since the filtration unit 14 is installed on the water tank lid 13b of the water tank 13, the user can easily perform maintenance such as replacement of the filtration unit 14 by pulling the water tank 13 out of the air purifier 1.
Further, since the water purification unit 16 is provided on the water supply protrusion 13b3 of the water tank lid 13b, maintenance such as manufacture and replacement of the water purification unit 16 can be easily performed.

In addition, in this embodiment, although the case where the water purification unit 16 was provided in the water supply protrusion 13b3 of the water tank lid 13b was illustrated, if the water in the water tank 13 can be purified, the location where the water purification unit 16 is provided is the water tank lid 13b. Of course, it is not limited to the water supply protrusion 13b3.
In addition, although the case where the filtration unit 14 and the water purification unit 16 were provided was illustrated in this embodiment, it is also possible to provide only the filtration unit 14, for example.

  Moreover, in this embodiment, although condensed water was filtered with the filtration unit 14 and the structure which condenses condensed water in the inside of the filtration unit 14 was illustrated, it comprised so that only the condensed water might be filtered with the filtration unit 14. Also good. In this case, the finer granules of the active ion granules 14c have a larger area where the condensed water hits the active ion granules 14c, and more active ions can be eluted into the condensed water. Therefore, in this case, finer particles of the active ion granules are desirable.

Note that the same filtration effect can be obtained even if the filtration unit 14 is installed at the outlet of the condensed water discharge hole 11c1 of the condenser 11 as shown in the modification of FIG.
Moreover, in this embodiment, the filtration unit 14 disinfects the nonwoven fabric filter of the filter for filtering out the foreign material in condensed water with a woolen fabric, the activated carbon of the adsorbent which removes the pigment | dye and smell of condensed water by adsorption | suction, miscellaneous bacteria, mold fungi, etc. Exemplified the case of having an active ion granule of a disinfectant for the purpose, but the constitution having only a filter such as a non-woven fabric filter, or an adsorbent such as activated carbon including a filter such as a non-woven fabric filter, disinfecting an active ion granule, etc. It is also possible to have a configuration having any of the agents.

Moreover, in this embodiment, although the case where the water purification unit 16 had the active ion granule 16c was illustrated, it has the structure which has activated carbon, such as an adsorbent which removes the pigment | dye and smell of condensed water by adsorption | suction other than the active ion granule 16c. It is also possible to do.
In this embodiment, the non-woven filter is used as a filter for filtering out foreign substances in the condensed water, and the active material is used as a disinfectant for sterilizing activated carbon, germs, fungi, etc. Examples of ion granules are shown, but filters, adsorbents, and disinfectants may be used other than non-woven fabric filters, activated carbon, and active ion granules as long as they can filter, adsorb, and disinfect, respectively. It is not limited to non-woven fabric filters, activated carbon, and active ion granules.

  Moreover, in this embodiment, when providing the filtration unit 14 in the exit part of the water collecting hole 13b1 of the water tank 13, and providing in the exit part of the condensed water discharge hole 11c1 of the condenser 11, the filtration unit 14 was illustrated. Can be provided anywhere on the path from the condensed water discharge hole 11c1 of the condenser 11 to the water in the water tank box 13a of the water tank 13.
