  Among the humidifiers, the one that heats and evaporates the water in the aquarium with infrared rays as in Patent Document 2 is provided with a reflecting member for the purpose of efficiently collecting the infrared rays emitted from the infrared heater into the water in the aquarium. There is. Such a reflecting member reflects infrared rays directed toward itself and directs them toward the water in the aquarium. However, the infrared rays also absorb some heat. Therefore, in such a humidifier, it is desirable to provide a structure for cooling the reflecting member.

  An object of the present invention is to provide a humidifying device that includes a reflecting member that reflects infrared rays and that has a simple structure for cooling the reflecting member.

  The humidifier according to the first invention includes a water tank, an infrared radiation member, a reflecting member, and a cover member. The infrared reflecting member is disposed in the first space close to the water in the aquarium and emits infrared rays. The reflecting member is disposed on the opposite side of the infrared radiation member from the water tank side. The reflection member partitions the first space and the second space and reflects infrared rays from the infrared radiation member. The second space is a space farther from the water tank than the first space, and is formed between the cover member and the reflecting member. The cover member is disposed on the side opposite to the infrared radiation member side of the reflection member. And in this humidifier, the air flow path containing 1st space and 2nd space is formed, and the flow of air arises in the air flow path.

Here, the infrared rays radiated from the infrared radiating member are reflected directly or by the reflecting member and travel toward the water in the aquarium. Thereby, water is heated mainly by radiation. The water thus heated evaporates into the first space, and the vapor is supplied to the humidification target space along the air flowing through the air flow path including the first space.
Further, here, since the air flows also in the second space formed between the cover member and the reflecting member, the reflecting member is cooled. The air flow for cooling the reflecting member is an air flow for supplying steam from the first space to the humidification target space, and is not a separate air flow generated only for cooling the reflecting member.

Thus, since the air flow path including the first space and the second space is formed here, both functions of cooling the reflective member and transporting the vapor are realized by one air flow, and the reflective member The structure for cooling the battery becomes simple.
The humidifier according to the second invention is the humidifier according to the first invention, wherein the air flowing through the air flow path flows through the second space before flowing through the first space.

  Here, the air that has cooled the reflecting member through the second space formed between the cover member and the reflecting member flows into the first space close to the water in the aquarium. Therefore, water is heated not only by the radiant heat from the infrared radiating member or the reflecting member but also by air warmed by cooling the reflecting member. That is, the water in the water tank is heated more efficiently, and evaporation is promoted.

  A humidifying device according to a third aspect of the present invention is the humidifying device of the second aspect, wherein the reflecting member is formed with a communication portion that communicates the first space and the second space. Further, the humidifier is further formed with an air supply channel and an air discharge channel. The air supply flow path is a flow path for sending air into the space on the opposite side to the communication portion side in the second space. The air discharge flow path is a flow path for sending air from the space on the opposite side to the communication portion side in the first space to the humidification target space.

  Here, the first space and the second space are communicated with each other by the communicating portion of the reflecting member, and air is fed into the second space from the air supply flow path on the side opposite to the communicating portion. From the air, air is sent out to the humidification target space by the air discharge passage. Therefore, as the air flow in the air flow path, the air sent from the air supply flow path to the second space flows into the space on the opposite side of the second space from which the air has been sent, and from there It flows to the first space through the communication portion, further flows to the space on the opposite side of the first space from the communication portion side, and finally toward the air discharge channel. Because of such an air flow, the reflecting member is reliably cooled from the communicating portion side to the opposite side. Moreover, the air flowing through the first space also flows in a portion close to water from the communicating portion side to the opposite side, so that the heating efficiency of the water in the water tank is improved.

  The humidifying device according to a fourth aspect of the present invention is the humidifying device according to any one of the first to third aspects of the invention, wherein the infrared radiating member is adjacent to the main body that radiates infrared rays and requires cooling. And a cooling unit. The humidifier further includes a shielding member. The shielding member is disposed in the vicinity of the portion requiring cooling of the infrared radiation member, and shields infrared rays from the main body. The shielding member is cooled by the air flowing through the air flow path including the first space and the second space.

Here, the air flowing through the air flow path including the first space and the second space realizes both functions of cooling the reflecting member and transporting the vapor, and also cools the shielding member. Thereby, it becomes possible to cool the cooling required part of an infrared radiation member with a shielding member, and it becomes unnecessary to provide another apparatus which cools a cooling required part.
A humidifier according to a fifth aspect of the present invention is a humidifier that heats and evaporates water in a water tank with an infrared radiation member, and includes a reflective member, a cooling air flow path, and an air guide flow path. The reflecting member reflects the infrared radiation emitted from the infrared radiation member and directs it toward the water in the aquarium. The cooling air flow path is an air flow path for cooling the reflecting member. The air introduction path is a flow path that guides the air that has flowed through the cooling air flow path to the water space above the water tank.

Here, the infrared rays radiated from the infrared radiating member are reflected directly or by the reflecting member and travel toward the water in the aquarium. Thereby, water is heated mainly by radiation. The water thus heated evaporates into the water space, and the steam is supplied to the humidification target space.
Moreover, since the flow path for cooling the reflecting member is formed here, the reflecting member is cooled. And the air which cools a reflective member flows into an aerial space from an air introduction path. That is, since the air introduction path is formed here, the reflecting member can be cooled using the flow of air flowing from the water space to the humidification target space.

As described above, since the air introduction path is configured to flow air from the cooling air flow path to the water space, both the functions of cooling the reflecting member and transporting the steam can be achieved by one air flow. This is realized and the structure for cooling the reflecting member is simple.
In addition, here, the air that has cooled and warmed the reflecting member in the cooling air flow path flows into the water space above the water tank. Therefore, water is heated not only by the radiant heat from the infrared radiating member or the reflecting member but also by air warmed by cooling the reflecting member. That is, the water in the water tank is heated more efficiently, and evaporation is promoted.

  The humidifying device according to the sixth aspect of the present invention is the humidifying device of the fifth aspect, wherein the infrared radiation member is disposed above the water in the aquarium. Moreover, the lower surface of the reflection member is a reflection surface, and is disposed above the infrared radiation member. The humidifier further includes a cover member. The cover member covers the reflection member from above and forms a cooling air flow path together with the upper surface of the reflection member.

In the humidifier according to the first invention, since the air flow path including the first space and the second space is formed, both functions of cooling the reflecting member and transporting the vapor are realized by one air flow, The structure for cooling the reflecting member is simplified.
In the humidifier according to the second aspect of the invention, water is heated not only by the radiant heat from the infrared radiating member and the reflecting member but also by air warmed by cooling the reflecting member. That is, the water in the water tank is heated more efficiently, and evaporation is promoted.

In the humidifying device according to the third aspect of the invention, the reflecting member is reliably cooled from the communicating portion side to the opposite side. Moreover, the air flowing through the first space also flows in a portion close to water from the communicating portion side to the opposite side, so that the heating efficiency of the water in the water tank is improved.
In the humidifying device according to the fourth aspect of the invention, the required cooling part of the infrared radiation member can be cooled by the shielding member, and there is no need to provide another device for cooling the required cooling part.

  In the humidifying device according to the fifth and sixth inventions, since the air introduction path is formed, the reflective member can be cooled using the flow of air flowing from the water space to the humidifying target space. The structure for cooling the reflecting member is simple.

When the sirocco fan 20 including the fan rotor 21 and the motor 22 is operated, air is sucked into the casing 11 from the upper suction port 16, the side suction port 17, and the front suction port 18 formed in the casing 11 (see FIG. 8 (see the dashed-dotted arrows A11, A12, A13), the air is cleaned while passing through the filter unit 24 as shown in FIG. 11 is supplied into the room as clean air from the blowout port 15 formed on the upper surface of 11 (refer to the arrow A1 of the one-dot chain line in FIG. 8).

  As shown in FIG. 2, the filter unit 24 includes a prefilter 41, a plasma ionization unit 42, a first photocatalytic filter 48, a second photocatalytic filter 45, an inverter lamp 47, and a third photocatalytic filter 46. Has been. The pre-filter 41 is disposed on the foremost side of the filter unit 24 and removes relatively large dust and dust. As the prefilter 41, a dustproof net such as a synthetic resin fiber is employed. The plasma ionization unit 42 is disposed behind the prefilter 41. The plasma ionization unit 42 charges the smoke, dust, pollen, and other dirt particles that have passed through the prefilter 41 by applying a strong charge, and collects particles in the first photocatalyst filter 48 and the like to be described later. Increase efficiency. The first photocatalytic filter 48 is disposed behind the plasma ionization unit 42. The first photocatalytic filter 48 is formed by laminating an electrostatic filter 43 for adsorbing particles charged by the plasma ionization unit 42 and a titanium oxide filter 44 containing titanium oxide having a photocatalytic action.

The photocatalytic action of the photocatalytic filters 47, 48, 45 is activated.

<Composition of humidification part>
As shown in FIGS. 1 and 8, the humidifying unit 50 is disposed on the back side (left side in FIG. 8) of the partition plate 19 that forms the back side of the fan installation space that houses the sirocco fan 20 in the air cleaning unit 10. And provided in a space surrounded by the partition plate 19 and the humidifying unit cover 59. The humidifying unit 50 mainly includes a steam generation unit 51, a steam transfer channel member 52, and a water supply tank 53.

[Vapor transfer channel member]
The steam transfer channel member 52 is a hose-like member, and guides the steam generated by the steam generation unit 51 to the upper opening 19b of the partition plate 19 shown in FIG. To the clean air flow A1.
[Water tank]
The water supply tank 53 is a resin-made airtight container, and discharges internal water from the water supply port 53b formed in the lower end of the water supply cap 53a shown to FIG.7 and FIG9 (A), (B). Specifically, when the water surface Ws of the evaporating dish 60 described later becomes lower than the water supply port 53b, external air enters the inside of the water supply tank 53 from the water supply port 53b, and the internal water corresponding to that amount. The water is discharged from the water supply port 53b to the evaporating dish 60. For this reason, when there is water inside the water supply tank 53, the height position of the water supply port 53b of the water supply tank 53 and the height position of the water surface Ws of the evaporating dish 60 automatically match. The water supply cap 53a has a closing member that blocks the flow of water to the water supply port 53b by the weight of the internal water so that the internal water does not fall from the water supply port 53b when the water supply tank 53 is lifted. 53c is provided. When the water supply tank 53 is set on the evaporating dish 60, the closing member 53c is lifted relatively to the water supply port 53b by a columnar closing release member 66a extending from the bottom 61 of the evaporating dish 60 (FIG. 7).

[Steam generation unit]
The steam generation unit 51 is a unit that heats the water supplied from the water supply tank 53 into steam, and discharges the steam to the steam transport flow path member 52. As shown in FIGS. 3 to 7, the steam generation unit 51 mainly includes an evaporating dish 60, an infrared lamp 70, a reflecting plate 80, and a reflecting plate cover 90.

  The evaporating dish 60 is a water tank that stores the water supplied from the water supply tank 53, and includes a bottom portion 61 and side portions 62 and 63. The evaporating dish 60 is elongated as shown in FIG. The evaporating dish 60 may employ an infrared lamp 70 as a heat source, and a depth dimension D (see FIG. 7) that is a water depth in a normal state (not tilted) is set to be small. Here, with respect to the length L in the longitudinal direction of the evaporating dish 60, the water depth D of the evaporating dish 60 is set to 1/15 to 1/30. That is, the length L in the longitudinal direction of the evaporating dish 60 is 15 to 30 times the water depth D of the evaporating dish 60. Specifically, the length L in the longitudinal direction of the evaporating dish 60 is 350 mm, and the water depth D of the evaporating dish 60 is 15 mm. In addition, the depth dimension of the evaporating dish 60 is set to twice the water depth D.

A water supply port 53 b of a water supply tank 53 that supplies water to the evaporating dish 60 is set at a position of the water depth D of the evaporating dish 60. That is, the water supply port 53b of the water supply tank 53 is set at a position higher than the bottom 61 of the evaporating dish 60 by a depth dimension D as shown in FIG.
In addition, the water supply portion 66 that receives water in the evaporating dish 60 is located at the longitudinal center of the evaporating dish 60. A closing release member 66a for lifting the closing member 53c of the water supply cap 53a is provided at the center in the longitudinal direction of the evaporating dish 60. It is supplied to the portion 66 (the central portion in the longitudinal direction of the evaporating dish 60) (see the arrow indicated by the dotted line in FIG. 7).

  The infrared lamp 70 is a heater that extends horizontally long along the longitudinal direction of the evaporating dish 60, and is mainly located on a main body 71 that emits infrared light and on both sides of the main body 71, as shown in FIG. 4. It is comprised from the edge parts 74 and 75. FIG. The main body 71 is disposed in the first space S <b> 1 that is an upper space of the evaporating dish 60, and includes a heating core 72 that generates heat by supplied power and a quartz glass 73 that covers the heating core 72. An inert gas is filled between the heating core 72 and the quartz glass 73, and even if the heating core 72 exceeds 1000 ° C., the surface of the quartz glass 73 is about 400 ° C. The end portions 74 and 75 are portions that play a role of being supported by holding members 77 and 78 that are fixed on the evaporating dish 60 and supply power to the heating core 72. The end portions 74 and 75 of the infrared lamp 70 on which components relating to power supply are provided are cooling-requiring portions that require cooling. In order to cool the end portions 74 and 75 of these infrared lamps 70, the holding members 77 and 78 also serve as shielding members that prevent the infrared rays radiated from the main body portion 71 from reaching the end portions 74 and 75. Fulfill. And the holding members 77 and 78 which play a role as such a shielding member are air-cooled by an air flow A2 which will be described later. That is, the air flow A2 indirectly cools the end portions 74 and 75 of the infrared lamp 70 by air-cooling the holding members 77 and 78.

  The reflecting plate 80 is disposed above the main body 71 of the infrared lamp 70, reflects the infrared radiation radiated upward from the main body 71, and directs it toward the water in the evaporating dish 60 (indicated by a two-dot chain line in FIG. 7). (See arrow A72). As shown in FIG. 5, a concave portion 81 is formed in the reflecting plate 80 for the purpose of ensuring the space above the water supply portion 66 of the evaporating dish 60 for the water supply tank 53. The infrared lamp 70 is disposed on the front side (the right back side in FIG. 5) with respect to the recessed portion 81 of the reflecting plate 80, and the infrared lamp 70 and the reflecting plate 80 do not interfere with each other. Further, a vapor discharge portion 82 is formed on the right side portion of the reflecting plate 80, and an upper and lower communication portion 83 is formed on the left end portion of the reflecting plate 80. The steam discharge part 82 is a cylindrical part, and communicates the first space S1 between the water surface Ws of the evaporating dish 60 and the reflecting plate 80 and the steam transport flow path member 52 as shown in FIGS. 5 and 7. The flow path for making it form is formed. The upper and lower communication portion 83 is a recessed portion, and forms a flow path for connecting the first space S1 and the second space S2 above the reflecting plate 80 together with the holding member 77.

  The reflection plate cover 90 is a member that covers the second space S2 above the reflection plate 80 and makes the second space S2 a substantially sealed space, and is disposed on the opposite side of the reflection plate 80 from the infrared lamp 70 side. Yes. As shown in FIG. 6, the reflector cover 90 is formed with a recess 91 provided for the same reason as the recess 81 of the reflector 80 and a circular hole 92. The circular hole 92 is an opening for connecting the vapor transport flow path member 52 and the vapor discharge part 82. Further, as shown in FIGS. 6 and 7, at the right end portion of the side plate on the front side (the air purifying unit 10 side) of the reflector cover 90, there is a lower portion of the fan installation space where the sirocco fan 20 is installed and the second end. A front-rear communication portion 93 for communicating with the space S2 is formed. This front-rear communication part 93 is connected to a lower opening 19a (see FIG. 8) formed in the partition plate 19 between the air cleaning part 10 and the humidification part 50, and the steam generating unit 51 from the fan installation space of the sirocco fan 20 is connected. It plays a role of taking in air into the second space S2 (see an arrow A2 of a one-dot chain line in FIG. 8).

  In the steam generation unit 51 configured as described above, one air flow A2 indicated by arrows A21 to A25 is generated as shown in FIG. This air flow A2 is generated by the pressure difference between the upper and lower portions of the fan installation space of the sirocco fan 20, that is, the pressure difference between the space near the lower opening 19a and the space near the upper opening 19b of the partition plate 19 in FIG. Referring to FIG. 7, first, air passes from the lower part of the fan installation space of the sirocco fan 20 through the lower opening 19 a of the partition plate 19 and the front-rear communication part 93 of the reflector cover 90, and the air is supplied to the steam generation unit 51. 2 flows into the space S2 (see arrow A21). This air flows from the right to the left in the second space S2 (see arrow A22). At this time, heat is removed from the upper surface 80a which is the surface opposite to the lower surface (reflecting surface 80b) of the reflecting plate 80, and the air is warmed. In other words, the reflecting plate 80 is cooled. Then, the air that has reached the left end of the second space S2 passes through the vertical communication portion 83 and descends to the first space S1 below (see arrows A23 and A24). At this time, the holding member 77 is cooled by the air flow. The air thus warmed flows from the left to the right in the first space S1 on the water where the main body 71 of the infrared lamp 70 is disposed, and promotes the evaporation of the water in the evaporating dish 60. The air that has reached the right end of the first space S1 cools the holding member 78, and then flows from the vapor discharge portion 82 formed in the reflector 80 to the vapor transport flow path member 52, and finally. As shown in FIG. 8, the air flows through the upper opening 19b of the partition plate 19 and merges with the clean air flow A1 blown upward from the sirocco fan 20.

That is, the humidifying unit 50 includes a space formed by the front and rear communication units 93, a second space S2, a space formed by the upper and lower communication units 83, a first space S1, and a space formed by the steam discharge unit 82. An air flow path is formed, and an air flow A2 is generated in the air flow path.
<Operation of humidifier of air cleaner>
In the humidifying unit 50 of the air cleaner, the infrared rays radiated from the main body 71 of the infrared lamp 70 are reflected directly or by the reflecting surface 80b of the reflecting plate 80 toward the water in the evaporating dish 60 (see FIG. 7). (See arrows A71 and A72 of two-dot chain lines). Thereby, the water of the surface layer in the evaporating dish 60 which absorbed the infrared rays of a predetermined wavelength is heated and evaporated. The steam generated by the evaporation of water joins the flow A1 of clean air blown upward from the sirocco fan 20 on the air flow A2, and is supplied into the room to humidify the room (see FIG. 8).

<Characteristics of humidifier of air purifier>
(1)
In the humidifying unit 50 of the air cleaner, the reflector 80 is covered with the reflector cover 90 to form the second space S2 on the reflector 80, and the air flow A2 is passed through the second space S2, thereby reflecting the reflector. 80 cooling is aimed at. Furthermore, in the humidification part 50, the air which cooled the reflector 80 and was warmed is guide | induced to the 1st space S1 on water by the up-and-down communication part 83, and is utilized for acceleration | stimulation of water evaporation.

  Thus, in the humidification part 50, the cooling of the reflecting plate 80, the evaporation of water, and the transport of steam are performed by one air flow A2, and the simplification of the structure is realized. In addition, the cost can be reduced compared to the case where the upper surface 80a of the reflecting plate 80 is covered with a heat insulating material. Furthermore, since the air flowing over the water is warmed, the evaporation of water can be efficiently promoted.

(2)
In the humidifying part 50 of the air cleaner, the first space S1 and the second space S2 are communicated with each other by the upper and lower communication parts 83 of the reflector 80, and the second space S2 is located on the opposite side (right side) to the second communication part 83. Air is sent into the space S2 by the front-rear communication part 93, and air is sent out from the first space S1 to the steam transfer flow path member 52 (which in turn is to be humidified) by the steam discharge part 82. Therefore, as the air flow A2, the air sent from the front and rear communication part 93 to the right part of the second space S2 flows to the left part of the second space S2, and from there through the vertical communication part 83, the air in the first space S1. It flows to the left part, further flows to the right part of the first space S1, and finally flows toward the steam discharge part 82. Because of this air flow A2, the reflector 80 is reliably cooled from the right part to the left part. Further, the air flowing in the first space S1 on the water also flows from the left part to the right part, and the evaporation efficiency of the water in the evaporating dish 60 is further improved.

(3)
In the humidifying unit 50 of the air cleaner, functions such as cooling of the reflecting plate 80 and transport of steam are realized by one air flow A2, and infrared rays radiated from the main body 71 of the infrared lamp 70 are end portions 74. Indirect cooling of the holding members 77 and 78 that serve as shielding members that prevent reaching 75 is also realized. That is, when the air flow A2 passes through the vertical communication portion 83 and descends from the second space S2 to the first space S1 or reaches the right end of the first space S1, the holding members 77 and 78 heated by infrared rays. Then, the end portions 74 and 75 of the infrared lamp 70 supported by the holding members 77 and 78 and in the vicinity of the holding members 77 and 78 are indirectly cooled.

In this way, the air flow A2 that cools the reflector 80 and transports the steam is used to cool the ends 74 and 75 of the infrared lamp 70 that needs to be cooled. Does not require a separate cooling device for cooling the end portions 74 and 75.
(4)
In the humidifier 50 of the air purifier, water is supplied from the water supply tank 53 into the evaporating dish 60 so that the water supply port 53b of the water supply tank 53 and the water surface Ws of the water in the evaporating dish 60 have the same height. Is done automatically.

Further, the humidifying unit 50 of the air purifier employs a configuration in which the water on the surface layer in the evaporating dish 60 is heated and evaporated by the infrared lamp 70, and it is desirable that the evaporating dish 60 be shallowly filled with water. .
However, when the evaporating dish 60 is so shallowly filled with water, attention must be paid to the phenomenon that the water surface Ws falls due to the inclination of the air purifier. In particular, since the elongate evaporating dish 60 is employed here, some measures should be taken against the inclination of the air cleaner in which one end and the other end in the longitudinal direction of the evaporating dish 60 have different heights in the vertical direction. is there. This is because, in general households, it is assumed that the air cleaner is used in a slightly inclined state due to the installation location.

  In view of this, the humidifying unit 50 of the air purifier employs a configuration in which water is supplied from the water supply port 53b of the water supply tank 53 to the central portion (supplied portion 66) instead of the end portion of the evaporating dish 60. Yes. Thereby, even when the air purifier is used in a slightly inclined state, the problem that the water surface Ws is excessively lowered (and the bottom 61 can be seen) at the end of the evaporating dish 60 is suppressed. Thereby, the infrared rays from the infrared lamp 70 heat not the water but the bottom 61 of the evaporating dish 60 and prevent the heating efficiency to water from being lowered.

This will be described with reference to FIG.
As is often seen in conventional humidifiers, when the water supply port 153b of the water supply tank 153 is disposed at a position facing the right end of the evaporating dish 60 (see the comparison shown in FIG. 9C), When the inclination that the right end portion of the evaporating dish 60 is lowered and the left end portion is raised as shown in FIG. When tilted to the extent shown in FIG. 9D, the bottom 61 is exposed at the left end of the evaporating dish 60.

On the other hand, in the case of the humidifying unit 50 of the air cleaner, the water supply is also performed when the air cleaner is inclined from the normal state shown in FIG. 9A to the state shown in FIG. 9B. Since the mouth 53b is disposed at a position facing the central portion of the evaporating dish 60, the bottom 61 is not exposed even at the left end of the evaporating dish 60 where the water depth becomes shallow, and a certain level of water depth is secured.
The inclination angle of the evaporating dish 60 in FIG. 9B and the inclination angle of the evaporating dish 60 in FIG. 9D are exactly the same.

  Thus, in the humidification part 50 of an air cleaner, even when the evaporating dish 60 inclines so that the height of the longitudinal direction one end and other end of the evaporating dish 60 may differ, the one end and other end of the evaporating dish 60 In this case, it is possible to prevent the water surface Ws from being extremely lowered. For this reason, even when the air purifier is used in an inclined state and the evaporating dish 60 is inclined, the infrared lamp 70 heats a portion of the evaporating dish 60 where there is no water, and the infrared lamp The problem that the transfer rate of the amount of heat from the water 70 to the water is reduced is suppressed to a small level.

<Other embodiments>
In the above embodiment, the reflector 80 is cooled by passing the air flow A2 into the second space S2 above the reflector 80, and the air heated by cooling the reflector 80 is guided to the first space S1 on the water. However, when only considering achieving the objective of simplifying the cooling of the reflector, a structure as shown in FIG. 10 can be used.

  The structure shown in FIG. 10 is the same as the evaporating dish 160 equivalent to the evaporating dish 60 in the above embodiment, the infrared lamp 170 equivalent to the infrared lamp 70, the reflecting plate equivalent to the reflecting plate 80 without the vapor discharge part 82 and the upper and lower communication part 83. 180 is a steam generation unit comprising a reflector cover 190 equivalent to the reflector cover 90 without the circular hole 92. This steam generation unit is formed with an air inlet 198 for introducing air from the lower part of the fan installation space and an air outlet 199 for discharging air to the upper part of the fan installation space.

  As a result, an air flow A102 indicated by arrows A121 to A124 as shown in FIG. 10 is generated. The air flow A102 flows from the lower part of the fan installation space into the steam generation unit via the air inlet 198 (arrow A121), and from there, the second space S102 between the reflector 180 and the reflector cover 190 and the water surface. The first space S101 is branched (arrows A122 and A123), merged at the air discharge port 199, and flows to the upper part of the fan installation space (arrow A124).

  In the steam generation unit shown in FIG. 10, an air flow A102 is generated by such a simple structure, and the air flow A102 cools the reflector 80 and promotes the evaporation of water. Even in such a structure, the cost can be kept low compared to the case where the upper surface 80a of the reflecting plate 80 is covered with a heat insulating material.

  The humidifying device according to the present invention has the effect of realizing both the functions of cooling the reflective member and transporting the vapor by one air flow and simplifying the structure for cooling the reflective member. Useful as a humidifier.
