DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply tank used for a humidifier or the like, and more particularly to a structure in which the amount of water inside can be easily and accurately visually recognized from the outside.

[0002]

2. Description of the Related Art A conventional water supply tank used for a humidifier or the like is, for example, a housing provided with a vertically extending window 1a, such as a water supply tank 2 shown in FIGS. 3 (A) and 3 (B). 1 and is provided with a water inlet 3 and is made of polyethylene resin or the like and has transparency, so that the remaining amount of water a injected from the water inlet 3 can be visually recognized from the window 1a. Met.

However, the water supply tank 2 may be formed in milky white, so that the water a
When visually recognizing the remaining amount, there were cases where it was not possible to accurately visually recognize the remaining amount from the window 1a due to, for example, the condition of indoor lighting.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a water supply tank which is used in a humidifier or the like so that the amount of water inside can be easily and accurately visually recognized from the outside. The purpose is to do.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is provided in a housing provided with a vertically extending window, having a water inlet and having transparency. A structure in which a bulge portion having a substantially C-shaped cross section that is close to or abutting is continuously formed, and a buoy that can move up and down in accordance with the amount of water injected from the water inlet is loosely fitted to the bulge portion. Has become.

Further, the buoy is formed of an elastically deformable material, and is formed to be slightly larger than an opening edge of the bulging portion and smaller than an inner diameter of the bulging portion. I have.

Further, the buoy is formed in a substantially spherical shape.

The buoy is formed in a hollow shape.

[0009] Further, the buoy is formed so that an upper edge of the outer portion floats substantially flush with a water surface.

Further, the buoy is colored so that the water level of the bulging portion can be easily recognized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings as an example of a water supply tank used for a humidifier or the like. 1 (A) to 1 (C),
As shown in FIG. 2 and FIG. 2, a water supply tank 2 used for a humidifier or the like is housed in a housing 1 of a humidifier provided with a window 1a extending vertically and provided with a water inlet 3 and has a permeability. A bulging portion 4 having a substantially C-shaped cross section is formed continuously in the vicinity of or in contact with the window portion 1a, and the bulging portion 4 is formed on the bulging portion 4 in accordance with the remaining amount of the water a injected from the water inlet 3. The buoy 5 that can move up and down is loosely fitted, whereby the buoy 5 that is loosely fitted to the bulging portion 4 can be easily visually recognized in the vertical position, so that the water supply is performed. The remaining amount of the water a in the water supply tank 2 can be accurately confirmed, and the remaining amount of the water a in the water supply tank 2 depends on, for example, the condition of indoor lighting, as in the above-described related art. Is not difficult to be visually recognized from the window 1a accurately.

The buoy 5 is formed of an elastically deformable material, and its outer diameter c is slightly larger than the opening edge b of the bulging part 4 and is larger than the inner diameter d of the bulging part 4. The buoy 5 can be easily and accurately loosely fitted to the bulging portion 4, and is separated from the bulging portion 4. The configuration is such that there is no such thing.

Further, since the buoy 5 is formed in a substantially spherical shape, a friction loss with respect to the wall surface of the bulging portion 4 can be suppressed to be small, so that the buoy 5 can move up and down smoothly. I have.

Further, since the buoy 5 is formed in a hollow shape, the buoy 5 is easily elastically deformed.
The configuration is such that it can be more easily loosely fitted to the bulging portion 4.

Further, since the buoy 5 is formed so that the upper edge of the outer portion thereof floats substantially flush with the water surface, the remaining amount of the water a in the water supply tank 2 can be accurately confirmed. In addition, the configuration is such that it is possible to immediately recognize that the remaining amount of the water a in the water supply tank 2 has decreased.

Further, since the buoy 5 is colored in a color in which the water level of the bulging portion 4 can be easily recognized, for example, by adopting a primary color, the remaining amount of the water a in the water supply tank 2 is increased. Can be confirmed more accurately.

With the above configuration, FIGS.
As shown in FIG. 2C and FIG. 2, the water supply tank 2 used for a humidifier or the like is housed in a casing 1 of the humidifier having a vertically extending window 1a, and a water inlet 3 is provided. Prepare and
A bulging part 4 having a substantially C-shaped cross section is formed continuously and has a permeability and is close to or in contact with the window part 1a, and the remaining amount of the water a injected from the water inlet 3 is formed in the bulging part 4. The buoy 5 which can be moved up and down according to the configuration is loosely fitted, so that the vertical position of the buoy 5 which is loosely fitted to the bulging portion 4 can be easily visually recognized, so that the water supply tank is provided. 2 can accurately check the remaining amount of water a in the water supply tank 2 depending on, for example, the condition of indoor lighting, as in the above-described related art. The water supply tank is configured such that it is difficult to accurately recognize the water from the window 1a.

[0018]

As described above, according to the present invention, there is provided a water supply tank used in a humidifier or the like so that the amount of water inside can be easily and accurately visually recognized from the outside.
