Section, water level detection section, and storage A Department was assumed to be integrally molded.

A humidifying tank, a communicating part, and a water level detecting part;
In addition, the water storage section is integrally formed of a non-magnetic material.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is constructed as described above. For example, by forming a water level detecting portion by die-casting with a non-magnetic material of aluminum, it is not affected by a magnet mounted on a float portion. In addition, the same performance as the conventional one can be obtained, and a water level detecting section into which a water level sensor is inserted can be formed by die casting.

Further, since the humidifying tank, the communicating portion, the water level detecting portion, and the water storage portion are integrally formed, the water surface is lower than the upper surface of the humidifying tank, so that there is no need to worry about water leakage from the humidifying tank mounting surface.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a heater for generating steam, which is fixed to the humidifying tank 2 by caulking or the like. When the steam generating heater 1 is energized, the water in the humidifying tank 2 boils to obtain steam.

At the upper part of the humidifying tank 2, an air outlet 3 for sending the steam into the room is detachably mounted, and is blown from a suction port 7 provided in a case body by a blower 6 composed of a fan 4 and a motor 5. The air is sucked in and discharged through the hole 8 provided in the outlet 3 together with the steam from the outlet 3 into the room.

Reference numeral 9 denotes a water supply tank for supplying water to the humidifier body. The lid 3 can be opened and closed by screwing a lid 3 into the water supply port. The water supply tank 9 and the lid 10 constitute a water supply section 11. are doing.

The lid 10 is provided with a valve body 1 which is opened and closed by pressing from the outside, as a means for supplying water to the humidifier body side.
3 are provided.

Reference numeral 12 denotes a valve body 13 provided on the lid 10 of the water supply tank 9 which is opened by pressing to supply water, and
This is a water storage unit that keeps the water obtained from the water supply unit 11 at a constant water amount and supplies the water to the humidification tank 2 while adjusting the water.

The humidifying tank 2 has a communicating part 14 for communicating the humidifying tank 2 and the water storage part 12 and a water level detecting part 16 for mounting a water level sensor 15 for detecting the water level of the water storage part 12.
Is integrated by die casting with an aluminum material.

The water level sensor 15 is divided into a float portion 17 and a switch portion 18. The float portion 17 is a foamed PP floating on water, and a magnet 19 is mounted. The switch portion 18 is turned on and off by a magnetic force 19. Then, when the float portion 17 moves up and down, the switch portion 18 is linked to turn on and off the heater 1 for steam generation.

Next, the operation of the above configuration will be described.

By energizing the steam generating heater 1,
The water in the humidification tank 2 boils to obtain steam.

Steam is sent into the room from a blow-out port 3 which is detachably mounted on the upper part of the humidifying tank 2.

Air is blown in from a suction port 7 provided in the case body by a blower 6 composed of a fan 4 and a motor 5, passes through a hole 8 provided in the blowout port 3, and together with steam, flows from the blowout port 3 to a room. Will be released.

The water supply tank 9 supplies water to the humidifier body by screwing the lid 3 and opening and closing a valve 13 which is opened and closed by pressing from the outside.

The water obtained from the water supply unit 11 is maintained at a constant amount in the water storage unit 12 and functions to supply the humidification tank 2 while adjusting the amount of water.

The humidifying tank 2 has a communicating part 14 for connecting the humidifying tank 2 and the water storage part 12, and a water level detecting part 16 for mounting a water level sensor 15 for detecting the water level of the water storage part 12.
Is integrated by die casting with an aluminum material.

The water level sensor 15 is divided into a float portion 17 and a switch portion 18. The float portion 17 is a foam PP floating on water, and has a magnet 19 attached thereto. The switch portion 18 is turned on and off by a magnetic force 19.

When the float unit 17 moves up and down, the switch unit 18 is linked, and the steam generating heater 1 is turned on and off.
Turn OFF.

For example, the aluminum material is die-cast, and the water level detecting unit 1 into which the water level sensor 15 is inserted.
6 can be formed, and the water level is lower than the upper surface of the humidification layer 2 by integrally forming the humidification tank 2, the communication part 14, the water level detection part 16, and the water storage part 12.

[0035]

As described above, according to the present invention, as described above,
The water level detection unit is made of aluminum non-magnetic material by die casting, so that the same performance as before can be obtained without being affected by the magnet attached to the float, and the water level sensor is made by die casting. Can be formed.

Therefore, by integrally forming the humidifying tank, the communicating part, the water level detecting part, and the water storing part, the water surface becomes lower than the upper surface of the humidifying tank, so that there is no need for a connecting part below the water surface, and there is no water leakage, and more safety. Humidifier could be provided.
