  When the humidifier is used as a single device, the design may be performed considering only the function as the humidifier. However, when the humidifier is incorporated in another device, there are various types of humidifier designs. It is assumed that there will be restrictions. For example, when designing an air purifier with a humidifying function in which an air purifier and a humidifying device are integrated, there is a particular demand for the shape and size of the humidifying device.

Here, a case is considered in which a long and narrow water tank must be adopted as a water tank filled with water due to space limitations of the humidifier.
In the case of adopting such a long and narrow water tank, there is no problem if the humidifier is always used in a state where it is installed on a horizontal surface. Problems arise. The inventors of the present application paid attention to this. The problem is that when applying a general water supply mechanism that raises the water surface by supplying water to the elongated tank when the water level drops, the water supply mechanism is located closer to the longitudinal end of the tank. If this is done, the bottom of the water tank may be visible at the other end of the water tank when the humidifier is tilted so that the end of the water tank is lowered. At this time, for example, water disappears from a part of the heating range of the heater, and the amount of heat generated from the heater is not efficiently transmitted to the water.

  An object of the present invention is to provide a humidifying device provided with an elongated water tank as a water tank for filling water, and the humidifying device in which the amount of heat emitted from the heater is efficiently transmitted to the water in the water tank even when the water tank is inclined. There is.

The humidifier according to the first aspect of the present invention includes an elongated water tank, a heater that heats the water in the water tank, and a water supply member that supplies water to the water tank. And a water supply member supplies water with respect to the center part of the longitudinal direction of a water tank.
Here, a long and narrow aquarium is adopted as the aquarium, but since water is supplied from the water supply member to the central portion in the longitudinal direction of the aquarium, one end and the other end in the longitudinal direction of the aquarium Even when the water tank is inclined so that the height of the water tank is different from that of the water tank, it is possible to prevent the water surface from being extremely lowered at one end or the other end of the water tank. For this reason, even when the humidifier is used in an inclined state and the water tank is inclined, the heater heats the water-free part of the water tank, and the amount of heat emitted from the heater is transferred to the water. The problem that the rate is reduced can be kept small.

The humidifying device according to the second invention is the humidifying device according to the first invention, wherein the heater is an infrared heater extending in the longitudinal direction of the water tank.
As described above, when an infrared heater is used, it is desirable to keep water in the water tank shallow, but when water is so shallow, special attention must be paid to the fact that the water surface is lowered by the inclination of the water tank. .

  In addition, here, since the water in the water tank is heated by the infrared heater extending in the longitudinal direction of the water tank, the water tank may be inclined and the water surface may fall at one end in the longitudinal direction of the water tank, and the bottom may be visible. Infrared rays radiated from the vicinity of one end of the heater will heat not the water but the bottom of the water tank. Such heating cannot be said to be effectively transferred to water.

On the other hand, in this invention, it is suppressing that a water surface falls extremely in the one end and other end of a water tank by taking the structure which supplies water with respect to the center part of the longitudinal direction of a water tank from a water supply member. .
The humidifying device according to the third invention is the humidifying device according to the first or second invention, wherein when the water supply port of the water supply member is positioned relatively above the water surface of the water tank, the water supply port The water supply member supplies water to the aquarium so that the water level is below the water surface.

Here, water is supplied to the water tank by the water supply member so that the height of the water supply opening and the water surface is the same, but because the water supply opening is located at the center instead of the end of the water tank, The problem that the water surface falls too much (and the bottom can be seen) at the end of the water tank that is positioned above when inclined is suppressed.
In the humidifier according to the fourth aspect of the invention, the length of the water tank in the longitudinal direction is 15 times or more the water depth of the water tank.

Here, the water tank is 15 times longer than the water depth and the water tank is stretched relatively shallow, but even if the water tank is tilted, the water level is extremely lowered at one end or the other end of the water tank. Is suppressed.
It should be noted that the present invention is particularly effective when a water tank having a length in the longitudinal direction of 20 times or more of the water depth is employed.

  In the humidifier according to the present invention, even when the humidifier is used in an inclined state and the water tank is inclined, the amount of heat emitted from the heater as a result of the heater unnecessarily heating the water-free portion of the water tank The problem that the transmissibility of water to water is reduced can be kept small.

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. 8 and blows upward from the blowout port 15 by the sirocco fan 20. 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, FIG. 9 (A), (B). Specifically, when the water surface Ws of the evaporating dish 60 described below 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 to form steam, and discharges the steam to the steam transport passage 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 longitudinal center of the evaporating dish 60, and the water in the water supply tank 53 is supplied from the periphery of the closing release member 66a through the water supply port 53b. 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 extending 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 humidifying part 50, and the steam generating unit 51 from the fan installation space of the sirocco fan 20 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 unit 50 of the air cleaner, the first space S1 and the second space S2 are communicated with each other by the upper and lower communicating portions 83 of the reflector 80, and the second side is located on the opposite side (right side) to the upper and lower communicating portions 83. Air is sent into the space S2 by the front-rear communication part 93, and the air is sent out from the first space S1 to the steam transfer flow path member 52 (by pulling, the indoor space to be humidified) by the steam discharge part 82. Therefore, as the air flow A2, the air sent from the front and rear communication portion 93 to the right portion of the second space S2 flows to the left portion of the second space S2, and from there passes through the vertical communication portion 83 to 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 such an 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 too low at the end of the evaporating dish 60 (and the bottom 61 can be seen) 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 9 (D) occurs, the position of the water surface Ws that is the same height as the water supply port 153 b becomes very low. 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 water in the evaporating dish 60 is heated by the infrared lamp 70, but the water is heated by a mica-type heater or the like attached to the bottom or side surface of the evaporating dish 60 instead of the infrared lamp 70. You can also do it. Also in this case, the present invention is effective.

  Even when the humidifier according to the present invention is used in an inclined state and the water tank is inclined, the heater heats a portion of the water tank where there is no water, and the amount of heat emitted from the heater is reduced. It is useful as a humidifier equipped with an elongate water tank.
