An annular steam outlet path 4 is formed.

[0005]

However, in the canopy 3 having the above-mentioned structure, the steam diffusion plate 6 is open all around and a steam outlet passage 4 is formed. Therefore, the tip of the steam outlet of the steam diffusion plate is directed obliquely. With this configuration, steam was blown out obliquely, and as a result, was blown up along the canopy surface. Further, the lower surface of the vapor diffusion plate was formed horizontally.

Therefore, when humidification is performed, water droplets accumulate on the concave horizontal surface below the vapor diffusion plate, and when the canopy 3 is opened by operating the open / close button 11 with the hinge portion 12 as an axis, the water droplets flow outward. It had the drawback that the power cord connection part on the side of the humidifier body and the table such as the table would get wet. Was.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a humidifier according to the present invention, FIG. 2 is an enlarged sectional view of a part of a canopy 3, and FIG.
The figure is an exploded perspective view showing the details of the recess of the canopy and the vapor diffusion plate,
FIG. 4 is a side view of the vapor diffusion plate.

In the humidifier 1 according to the present invention, as shown in FIG. 1, a heating tank 2 is disposed with a cylindrical space interposed inside an outer case 1 erected on a disk-shaped pedestal 8, A humidifier main body having a heater 5 attached to a lower outer periphery of the heating tank 2 is formed between the outer case 1 and the heating tank 2, and a canopy 3 is provided with a hinge 12 at an upper end opening of the main body. It is mounted so as to be openable and closable by a predetermined angle (for example, 100 °) as a center and to be detachable. The canopy 3 has a hinge 1
An open / close button 11 is provided on the side opposite to 2, and when the open / close button is pressed, the lock between the canopy and the main body is released, and the canopy can be opened. A power cord connecting portion 7 is formed in the outer case 1 directly below the hinge portion 12. The configuration so far is the same as the conventional one. The present invention differs from the conventional configuration in the following points.

That is, the canopy 3 is composed of a rib-shaped inclined bottom portion 13b having a hole 9 in the center and a vertical wall portion 13 connected thereto.
a with the inclined bottom 13
b, four ribs 18a, 18b, 18c, 18d are erected at intervals of 90 degrees from each other.
The gripping body 15 is formed so as to be able to grip the locking rod 6a of the first embodiment, and the rib 18d has a stepped portion 18e so that the rib 6c of the vapor diffusion plate 6 described later can pass therethrough.

The hinge 12 of the vertical wall 13a of the canopy 3
When the canopy 3 is opened by rotating the canopy 3 about the hinge 12 (see the conventional example in FIG. 5), the wall 13a located on the lower side has a circle facing the rib 18e of the gripping body 15. An arc-shaped band-shaped projection 16 is provided upright at an interval from the surface of the wall portion 13 so as to receive an arc-shaped lower projection 6b formed on a side portion of the vapor diffusion plate 6 described later.

Next, the vapor diffusion plate 6 housed in the recess 13 will be described. The vapor diffusion plate 6 has relatively small projections formed downward over the entire circumference of the lower surface of the disk-shaped plate, a locking bar 6a protruding at the center, and a diameter at the lower surface of the plate. A toe receiving rib 6c extending in the direction is erected so as to avoid the locking bar. The locking bar 6a is elastically reduced in diameter as a split structure, and is removably elastically locked in the holding hole 15a of the holding body 15.

Further, an arc-shaped lower projection 6b is formed on one side of the vapor diffusion plate 6, that is, a portion located below when the canopy 3 is rotated around the hinge portion 12 and opened. 6b fits snugly between the band-like projection 16 erected in the recess 13 of the canopy 3 and the vertical wall 13a. Thus, as shown in FIG. 1, the steam from the heating tank 2 reaches the steam diffusion plate 6 through the steam holes 9, and in this case, the steam outlet path 4 on the hinge side is formed by the cooperation of the strip-shaped projection 16 and the lower projection 6b. Since the steam is closed by the action, the steam is discharged upward only from the steam outlet passage 4 on the opposite side to the hinge portion 12 side.

At the end of the lower projection 6b of the diffusion plate 6, there is formed an inclined rib 6d which is inclined to the lower side of the plate as shown in FIG. When rotated and opened, water droplets flowing along the side surface of the steam diffusion number 6 hit the inclined rib 6d, and are collected from the back side (that is, the lower side) of the steam diffusion plate 6 into the heating tank by the inclined surface. become.

When using the humidifier 1 according to the present invention,
The canopy 3 is opened by pressing the open / close button 11. In this state, a predetermined amount of water is poured into the heating water tank 3. Then, the canopy 3 is closed and the heater 5 is energized via the power cord connection. Then, the water in the heating water tank 3 is heated by the heater 5 to become steam, passes through the steam passage hole 9 of the canopy 3, and then humidifies via the arc-shaped steam outlet path 4 opened to the opposite side to the hinge 12. It is discharged almost vertically upward of the vessel 1. In this case, since the hinge portion 12 side of the recess 13 is closed by the band-shaped protrusion 16 and the lower protrusion 6b of the vapor diffusion number 6, as described above, the steam is opened on the side opposite to the side where the band-shaped protrusion is formed. Released only from the steam outlet channel
Moreover, the presence of the vertical wall 13a of the recess 13 causes the vapor to rise almost vertically and be discharged.

[0024]

According to the present invention described above, in the present invention, when the canopy of the vapor diffusion plate is opened, the lower portion (hinge portion) of the vapor diffusion plate is formed by the band-shaped projection and the lower projection of the vapor diffusion plate. By closing the steam outlet, water droplets accumulated in the steam outlet when the canopy is opened are prevented from flowing out of the outlet through the outlet. Further, since the configuration is such that the peripheral wall of the recess is upright, the steam rises straight upward, and therefore the steam does not crawl on the upper surface of the canopy, so that it is possible to prevent the accumulation of water droplets around the outlet.

[0025] Further, on the lower surface of the vapor diffusion plate, between the locking bar and the lower projection, a catching rib projecting from one end to the other end is formed. Water droplets attached to the back surface can be received and collected in the heating tank, and if an inclined rib is formed near the end of the arc-shaped downward projection of the vapor diffusion plate, water droplets flowing on the side surface of the vapor diffusion plate are externally exposed. Can be prevented from flowing out.
Further, since the edge of the steam outlet of the steam diffusion plate is vertically projected downward, it is possible to prevent water droplets around the edge from flowing out.
