In the fan casing 6, a sirocco fan 9 rotated by driving a motor is provided. The sirocco fan 9 has a substantially cylindrical shape and is provided with a plurality of fins arranged side by side on the outer periphery. Then, by the rotation of the sirocco fan 9, outside air is introduced into the fan casing 6 through an intake port (not shown) formed in the lower part of the side wall of the container body 1, and is blown to the air guide portion 7. Has become.
[0011]
The air guide portion 7 is formed in a substantially inverted triangular shape whose cross-sectional area gradually increases upward.
[0012]
A heat sink (not shown) is exposed from the board 10 attached to the board attachment section 8 in the communication path connecting the fan casing 6 and the air guide section 7. This heat sink is used for heat radiation of electronic components mounted on the substrate 10.
[0013]
As shown in FIG. 5, the blowing unit 5 includes a blowing guide section 11 disposed to cover an upper opening of the air guide section 7, and a steam flow path to be described later above the blowing guide section 11. And a steam discharge section 12 for discharging water vapor supplied from the apparatus.
[0014]
Cylindrical air guide ports 13 are formed on both sides of the blow-out guide section 11, and ridges 14 having substantially the same height are continuous at predetermined intervals inside the air guide ports 13. Each air guide port 13 is opened and closed by an opening / closing member 15 slidably provided along the ridge 14. As shown in FIG. 4, the opening / closing member 15 includes an opening / closing plate 16 for opening and closing the air guide ports 13 on both sides, and an operation unit 17 protruding from the back of the container body 1 at the center. The two air guide ports 13 are opened in a state where the operation unit 17 is located at the center, and the air guide ports 13 in the moving direction are gradually closed by sliding to one of the air guide ports 13. .
[0015]
In addition, a steam guide 18 is formed at the center of the blow-out guide 11, as shown in FIGS. 2 and 5B. The steam guide portion 18 includes a rectangular tube portion 19 protruding downward, and a cylindrical portion 20 protruding further forward from a side wall thereof. A ball 21 is disposed in the rectangular tube portion 19 so as to be movable up and down, and an upper opening thereof is covered by a flat plate 23 having a sealing hole 22 that can be sealed by the ball 21. The upper side of the outer surface of the container main body 1 is formed so as to be inclined inward, so that when the humidifier falls down, the upper side always faces downward. Therefore, if the humidifier falls, the ball 21 rolls on the rectangular cylindrical portion 19 to seal the sealing hole 22 and prevents the water in the inner container 2 from leaking to the outside. A packing 24 is provided on the outer periphery of the cylindrical portion 20.
[0016]
The steam discharge part 12 is attached to the upper part on the back side of the container body 1, and the steam discharge port 25 is formed by slits provided in three rows inside the upper part of the air guide port 13. Accordingly, when one of the air guide ports 13 is closed by the open / close plate 16 of the open / close member 15, the air from the other air guide port 13 flows while being guided by the inner surface of the upper wall of the steam discharge unit 12. The air is blown obliquely through the steam discharge port 25.
[0017]
1 and 7, an engagement receiving portion 1a is formed at the upper end on the front side of the container body 1. As shown in FIG. The lock receiving portion 1 a is provided at a portion corresponding to the display panel 1 b formed at the center of the front surface of the container main body 1 and protrudes from the upper end of the container main body 1. When the container body 1 is covered with a lid 3 described later, a hook 3b provided on the lid 3 is locked, and the lid 3 is maintained in a closed state. In addition, recesses 1c are formed on both sides of the upper end of the container body 1. The recess 1c is used when the water contained in the inner container 2 is discarded. In this case, the lock receiving portion 1a functions as a so-called weir, and the discarded water is applied to the display panel 1b. To prevent In addition, the presence of the lock receiving portion 1a makes it possible to visually recognize that the structure is such that water is drained using the recess 1c instead of draining from the front side where the display panel 1b is provided. Has become. A water level gauge 1d extending from the inner container 2 is provided on the back side of the display panel 1b.
[0018]
A heater 26 is provided on the bottom surface of the inner container 2 so that the stored water can be heated.
[0019]
The lid 3 includes an upper lid 27, an inner lid 28, and a lower lid 29, and the inner lid 28 and the lower lid 29 form a steam flow path. The inner lid 28 is integrated with the upper lid 27, and the lower lid 29 is screwed to the inner lid 28 with a packing 30 interposed at the outer edge. The lid 3 is attached to the container body 1 so as to be pivotable and detachable about a support shaft 31 provided on the upper lid 27.
[0020]
A steam inlet 32 is formed in a recessed position in the center of the lower lid 29. Further, a through hole 33 is formed in the lower lid 29 below the support shaft 31 so that the condensed water in the middle of the steam flow path can be returned to the inner container 2.
[0021]
A first concave portion 34 is formed at a position corresponding to the steam inlet 32 at the center of the inner lid 28. The first concave portion 34 prevents the steam from the steam inlet 32 from directly hitting the upper lid and becoming high in temperature. A second recess 35 communicating with the steam guide 18 is formed on the side (support shaft side) of the first recess 34. The second concave portion 35 is closed by a cap 36 having a through hole 36a, so that the flow of the steam changed downward by the first concave portion 34 can be further changed from above to the side. The reason why the steam flow path is complicated is that the hot water in the inner container 2 is hardly leaked when the humidifier falls.
[0022]
As described above, the lid 3 has a simple structure in which only the upper lid 27, the middle lid 28, and the lower lid 29 are combined. Moreover, the lid 3 has only a vapor passage formed therein. Moreover, it is removable from the container body 1. Therefore, it can be washed and is convenient for handling.
[0023]
In addition, a hook 3b is provided at a front portion of the lid 3 so as to be protruded and retracted by rotating the lever 3a. The hook 3b is engaged with and disengaged from the lock receiving portion 1a of the container main body 1 to keep the lid 3 closed or openable.
[0024]
Next, the operation of the humidifier will be described.
[0025]
In the humidifier, when a switch (not shown) is operated, energization of the heater 26 is started, and the water contained in the inner container 2 is heated. That is, instead of evaporating a part of the water, all the water in the inner container 2 is heated and boiled. Therefore, bacteria and the like do not propagate, which is very sanitary. Then, the steam generated by the heating flows into the lid 3 through the vapor inlet 32 of the lower lid 29, and the direction is changed downward in the first concave portion 34. Subsequently, after the direction is changed again by the second concave portion 35, the air is supplied into the blowing unit 5 through the steam guide 18 of the blow guide 11.
[0026]
At the same time, the rotation of the sirocco fan 9 is started by the driving of the motor, and outside air is introduced into the fan casing 6 via an intake port (not shown). The outside air introduced into the fan casing 6 is blown out from the air guide port 13 through the air guide section 7. From which air guide port 13 air is blown can be changed by operating the opening / closing member 15. That is, when the opening / closing member 15 is moved as shown in FIG. 6, the air blown upward from one air guide port 13 is changed in direction along the inner surface of the upper wall of the steam discharge section 12, and the steam guide section 18 is turned. Acts so as to be directed obliquely through the steam discharge port 25 (indicated by an arrow b in FIGS. 1 and 6). Therefore, for example, when the humidifier is placed in the corner of the room, one air guide port 13 may be closed so that the air flows toward the inside of the room. When both air guide ports 13 are opened, steam supplied from each of them is discharged upward (more precisely, forward) by colliding at the center (shown by an arrow a in FIGS. 1 and 5). .).
[0027]
In this way, the steam supplied from the inner container 2 to the blowing unit 5 is discharged from the steam discharge port 25 in accordance with the flow of the outside air taken in by driving the sirocco fan 9.
[0028]
In addition, when the drive of the humidifier is stopped by operating the switch, the power supply to the heater 26 is immediately stopped, but the rotation of the sirocco fan 9 continues for a predetermined time (for example, two minutes). Thereby, the invasion of water vapor into the ventilation path side is reliably prevented, and problems (such as propagation of bacteria) due to condensation in the ventilation path are prevented.
[0029]
Humidification by the humidifier is performed as described above, but when cleaning or the like becomes necessary, the lid 3 can be removed from the container main body 1 and washed in a round manner. Further, in the blowing unit 5 through which the steam passes, since the steam discharging portion 12 and the blowing guide portion 11 can be removed from the container body 1, this portion can also be easily cleaned.
[0030]
In the above-described embodiment, the air guide ports 13 are formed at two places. However, three or more air guide ports may be provided so that the air blowing direction can be changed to a plurality of directions.
[0031]
Further, in the above-described embodiment, the steam can be blown obliquely by the air guide port 13 and the steam discharge section 12 provided on both sides. However, as shown by a two-dot chain line in FIG. It may be possible to blow air out by forming it in a cylindrical shape that goes diagonally.
[0032]
【The invention's effect】
As is clear from the above description, according to the humidifier according to the present invention, the water in the inner container is boiled by the heating means, so that bacteria and the like do not propagate and are sanitary. Further, only the vapor flow path is formed in the lid, and the configuration is very simple. For this reason, it is possible to remove the lid from the container body and wash it in a circle, which is also sanitary.
