The air is humidified when passing through the moisturizing filter 12 holding water, and the humidified air is blown to the outside of the main body case 1 from the air outlet 8 through the air inlet 30 and the air outlet 29 of the air blower 3. - 特許庁

As shown in FIG. 4 , the body case 1 has a hollow portion 41 extending from an opening 40 provided on the front surface (one side surface) of the body case 1 to the back side of the body case 1 . The water storage container 11 is attachable to and detachable from the hollow portion 41 through the opening 40 . A feature of this embodiment is the structure of the water storage container 11 and the hollow portion 41 .

As shown in FIG. 5, the water storage container 11 is provided with a plurality of wheels 42 on the front side in the attachment/detachment direction of the water storage container 11 on the bottom or bottom surface of the water storage container 11 .

The wheel portions 42 are provided one by one at each of the two corners of the bottom surface of the water storage container 11 and are movable in the attachment/detachment direction of the water storage container 11 . The wheel portion 42 has an elastic wheel 42a, a rotating shaft 42b that rotatably supports the wheel portion 42, and a shaft fixing portion 42c that extends from the bottom surface of the water storage container 11 and fixes the rotating shaft 42b. ing. The rotating shaft 42b extends horizontally in a direction perpendicular to the direction in which the water storage container 11 is attached and detached.

The water storage container 11 has a plurality (two) of first protrusions 43 that protrude downward from the bottom surface 11a of the water storage container 11 and extend in the attachment/detachment direction of the water storage container 11 (the front-rear direction in the main body case). ing. The lower end of the wheel portion 42 protrudes downward from the lower end of the first protruding portion 43 .

As shown in FIG. 6 , the hollow portion 41 has an inclined surface 44 and a horizontal surface 45 on the lower surface inside the hollow portion 41 . The horizontal surface 45 is arranged on the back side of the inclined surface 44 in the attachment/detachment direction of the water storage container 11 . The inclined surface 44 is an obliquely upwardly inclined surface extending from the opening 40 into the main body case 1 (back side of the main body case 1). The horizontal surface 45 is a surface extending from the rear end of the inclined surface 44 in the attachment/detachment direction of the water storage container 11 (the rear side of the inclined surface 44 in the main body case 1) into the main body case 1 (the rear side of the main body case 1). .

In the above configuration, when the water storage container 11 is filled with water and the water storage container 11 is inserted into the hollow portion 41 through the opening 40, the wheel portion 42 of the water storage container 11 first comes into contact with the floor surface, and the first projecting portion 43 moves while contacting the lower inclined surface 44 in the cavity 41 (see FIG. 6). Next, when further inserted into the hollow portion 41, the water storage container 11 moves while the wheel portion 42 separates from the floor surface and the first protruding portion 43 comes into contact with the horizontal surface 45 on the lower surface of the hollow portion 41 (FIG. 7). reference). Furthermore, when it is further inserted into the hollow portion 41, it is mounted in the hollow portion 41 with the first projecting portion 43 in contact with the horizontal surface 45 of the lower surface of the hollow portion 41 (see FIG. 8).

In the above configuration, when the water storage container 11 mainly moves on the lower inclined surface 44 in the hollow portion 41, the water storage container 11 moves while the wheel portions 42 are in contact with the floor surface. As a result, since the water storage container 11 moves up the inclined surface 44, the weight of the water storage container 11 acts as a load on the user, but the wheels 42 cause friction between the water storage container 11 and the floor surface and the inclined surface 44. Reduced resistance and easier insertion.

Further, when the water storage container 11 moves mainly on the horizontal surface 45 of the bottom surface of the hollow portion 41 , the wheel portion 42 of the water storage container 11 does not contact the floor surface, and the first projecting portion 43 moves on the bottom surface of the hollow portion 41 . moves in contact with the horizontal surface 45 of . As a result, the water storage container 11 moves on the horizontal surface 45, and the frictional resistance between the first projecting portion 43 of the water storage container 11 and the horizontal surface 45 acts as a load on the user. 41, it is possible to reduce the tendency of the water storage container 11 to easily move from a predetermined position due to vibration or the like during operation of the humidifier. Furthermore, since the weight of the water storage container 11 does not act as a load on the wheel portion 42 during operation of the humidifying device, the durability of the wheel portion 42 is improved (see FIG. 9).

Further, as shown in FIG. 7, the water storage container 11 is configured so that the weight of the water in the water storage container 11 separates the wheel portion 42 from the floor surface. Specifically, the water in the water storage container 11 is stored on the far side in the attachment/detachment direction of the water storage container 11 (the front-rear direction in the main body case 1).

As a result, when the water storage container 11 moves along the lower inclined surface 44 in the hollow portion 41 and the back side surface of the water storage container 11 in the attachment/detachment direction of the water storage container 11 moves to the middle of the horizontal plane 45, the center of gravity of the water storage container 11 is moved. position moves from the inclined plane 44 to the horizontal plane 45 . Due to this movement of the center of gravity, the wheel portion 42 of the water storage container 11 is separated from the floor surface, and the first projecting portion 43 of the water storage container 11 contacts the horizontal surface 45 . As a result, the user does not have to lift the tilted water storage container 11 to level it, and mounting of the water storage container 11 is facilitated.

As shown in FIG. 5, a bottom surface 11a of the water storage container 11 protrudes downward from the bottom surface 11a and extends in a direction perpendicular to the attachment/detachment direction of the water storage container 11 (the front-rear direction in the main body case 1). direction) (see FIG. 5). The second projecting portion 46 is arranged on the front side of the water storage container 11 in the attaching/detaching direction from the wheel portion 42 . When the water storage container 11 is filled with water and inserted into the hollow portion 41 through the opening 40 and the water storage container 11 is moved while the wheel portion 42 is in contact with the floor surface, the first projecting portion 43 is positioned on the lower surface of the hollow portion 41 . , the second protrusion 46 comes into contact with the floor surface. The lower end of the wheel portion 42 protrudes downward from the lower end of the second projecting portion 46 .

As a result, it is possible to prevent the water storage container 11 from contacting the upper surface of the hollow portion 41 due to excessive lifting of the back side of the water storage container 11 in the attachment/detachment direction of the water storage container 11 . As a result, mounting of the water storage container 11 is facilitated.
