DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam generating humidifier.

[0002]

2. Description of the Related Art Various types of humidifiers have been developed as humidifiers for humidifying indoor air. The humidifier discharges steam obtained by steam generating means into a room (or a living space). Accordingly, a steam generating humidifier that humidifies the air is often used.

The steam generating humidifier is configured so that a predetermined amount of water can be constantly supplied to a boiler from a water supply tank, and the steam generated from the boiler is discharged into a room.

[0004]

In the case of the steam generating humidifier having the above-mentioned structure, since steam is generated by the boiler, calcium and other inorganic substances contained in the water accumulate in the boiler. Has a problem that it is difficult to clean the above-mentioned inorganic substances since it has a structure which cannot be usually attached and detached.

[0005] Further, since the boiler has a small capacity so as to be easily boiled, there is also a problem that the amount of generated steam does not increase.

[0006] The present invention has been made in view of the above, so as to boil water contained by heating the being freely out the water container itself directly, as well as facilitate the care, It is intended to obtain a large amount of generated steam.

[0007]

According to the basic structure of the present invention, as a means for solving the above-mentioned problems, a main body casing having a lid which can be opened and closed, and a main body casing having a cover which can be opened and closed are provided.
A water container which is out freely accommodating the electric heater to the water contained in the water vessel is heated to boiling, and the outside air introducing means for introducing the outside air into the water surface above the position of the water container, generated in the water container in the humidifier having a water vapor outlet that releases water vapor into the chamber, the water container, housing
At times, it is placed on the electric heater and
It is designed to directly heat the bottom of the water container.
The temperature of the water container is detected at the center of the electric heater.
Temperature detecting means is provided.

With this configuration, the electric heater
The water container itself, which is directly heated by the water container, acts as a water vapor generating means, and can generate a large amount of water vapor, and if the water container is taken out, it is necessary to take care of removing inorganic substances and the like precipitated in the water container. Easy to do. Further, since the outside air is introduced into the water container, the temperature of the water vapor discharged from the water vapor discharge port into the room is lowered, and safety is improved. Further, since the steam is forcibly released by introducing the outside air, it is possible to lower the heat retention temperature of the hot water in the water container, and it is safe even if the water runs down. And inside the electric heater
Since the temperature detection means is installed at the core, the temperature of the water container
The temperature of the water container can be controlled by detecting
it can.

In the basic structure of the present invention, the water container
At the time of taking out the water container, it is in an upright posture,
For carrying the water container in the storage position when storing it
When the handle is provided rotatably, the water container is
When the container is taken out, it is in an upright posture,
At the time of delivery, rotate the handle for carrying, which is in the storage position.
The water container is installed so that it can be moved freely.
It is easy to carry, and the handle is
It does not become evil.

[0010] The outside air introducing means may include: a blower provided in an area defined by the water container in the main body casing and having an outside air suction port formed therein; In the case of using the outside air introduction passage leading into the container, outside air can be easily introduced into the water container, and the amount of outside air introduced can be easily controlled by controlling the operation of the blower.

Further, when the outside air introduction passage is formed in the lid body and is made to communicate with the discharge port of the blower only when the lid body is closed, the outside air is supplied only when the lid body is closed. Since it is to be introduced into the container, efficient outside air introduction can be performed.

FIG. 4 shows a connection state of electric elements in the humidifier.

That is, the heating element 1 in the electric heater 4
0, as shown in FIG. 4, comprises a sheath heater 10a for 500 W and a sheath heater 10b for 300 W, for example, when heating and boiling the water W in the water container 3, the sheath heaters 10a and 10b. 800W
Heating, and after boiling, thermostat 1
1 energizes only the sheathed heater 10b and 3
Heating at 00 W (that is, heat keeping heating) is performed. 52 is an AC power supply, 53 is a main switch, 54
Is a temperature fuse, 55 is an empty-fire prevention switch, 56 is an operation display lamp, and 57 is a blower motor.

Incidentally, the electric elements of the humidifier can be controlled by a microcomputer board 58 as shown in FIG. In this case, a thermistor 59 that detects the temperature of the water container 3 is used instead of the thermostat 11 as a temperature detection unit that controls heating of the electric heater 4. Reference numerals 60 and 61 denote light emitting diodes that indicate “strong” and “weak” of the electric heater 4.

The humidifier configured as described above operates as follows.

After the water W is stored in the water container 3 and stored in the storage recess 7 of the main casing 1 and the lid 2 is closed, the power supply to the electric heater 4 is started, and Water W
Is heated and boiled at 800 W. After the boiling, the thermostat 11 (or the microcomputer board 58) switches to heating at 300W. At this time, the outside air A discharged from the blower 26 by driving the blower motor 57 is introduced into the water container 3 via the outside air introduction passage 35.

Then, the water W in the water container 3 boils to generate steam S. The steam S is discharged from the steam outlet 40 through the steam outlet 13 into the room, and is used for humidifying the indoor air. Is done.

When there is no more water W in the water container 3,
After the lid 2 is opened, if the handle 21 is raised in the standing posture (see FIG. 3), the water container 3 can be easily taken out, and the water W can be supplied to the water container 3.

Therefore, since the water container 3 itself functions as a water vapor generating means, a large amount of water vapor S can be generated, and the water S is deposited in the water container 3.
Care for removing inorganic like that can be easily performed if retrieve the water container 3. Further, since outside air is introduced into the water container 3, the temperature of the water vapor S discharged into the room from the water vapor discharge port 40 is lowered, and safety is improved.
Furthermore, since the steam S is forcibly released by the introduction of the outside air, the temperature of the hot water in the water container 3 can be lowered, and the water is safe even if the water falls down.

Since the upper opening of the water container 3 is covered by the inner lid 14, as shown in FIG. 2, even if the lid 2 is opened by the operation lever 50 of the lock mechanism 47 with the finger F, as shown in FIG. Since a large amount of steam S does not rise, safety is improved.

Further, since the water vapor discharge port 40 and the outside air inlet 12 are provided with the water stop valves 17 and 41, respectively, the hot water in the water container 3 flows out even if the water tank 3 falls. And the safety is further improved.
