[Action]

 By energizing the heating heater-3 to heat the heating tank 2, a certain amount of water stored in the heating tank 2 is gradually evaporated to generate a steam, and the steam is generated by the blower 15 The air is circulated through the steam flow passage 14 in the central portion of the guide cylinder 10 to be forcibly discharged into the room from the blow-off nozzle 18 in the upper part, and the entire room is satisfactorily humidified.

Further, at this time, air is naturally circulated from the small gap 22 between the instrument body 1 and the water supply tank 7 to the air flow path 11 between the guide tube 10 and the water supply tank 7, and the air just flows. It prevents the heat of the heating heater-3 and the heat of the high temperature steam flowing in the guide tube 10 from acting on the water heater 7 and affecting the water supply tank 7, thereby increasing the internal pressure of the water supply tank 7. It is possible to reliably prevent the abnormal water level due to.

Further, since this naturally aerated air is discharged upward from the outer circumference of the blow-out nozzle 18 above the guide cylinder 10, it is possible to promote the temperature reduction of the steam and the diffusion and discharge into the room. It always provides good steam humidification.

 Next, a steam humidifier according to the present invention will be described with reference to a preferred embodiment shown in the drawings. Reference numeral 1 is a flat oval instrument body made of synthetic resin. In the center, a heating tank 2 is provided with a bottomed tubular shape and the inner surface of the aluminum material is subjected to decalcification treatment with Teflon and the like. A heating heater 3 made of a planar band heater is fixed to the outer periphery of the side wall of the heating tank 2, and a certain amount of water stored inward is heated to generate a steam. is there.

A water receiving tank 4 communicates with an inflow port 5 formed at the bottom of the heating tank 2 through a communication pipe 6, and a valve element (not shown) in a water supplying portion 8 of a cartridge type water supplying tank 7. ) Is provided, and makeup water from the water supply tank 7 is supplied to the heating tank 2. The water supply tank 7 is made of a transparent synthetic resin and has a donut shape with a hollow central portion as well as its internal volume can be seen at a glance.

Reference numeral 10 is a guide tube made of a transparent synthetic resin that stands upright on the heating tank 2 and forms an air passage 11 for natural ventilation in the cavity of the water supply tank 7 when the water supply tank 7 is attached. The inner side of the inner cylinder 12 is airtightly communicated with the inner side of the heating tank 2 through the packing 13 to form a steam flow passage 14 for guiding the steam upward. At the same time, the outer periphery thereof constitutes a forced ventilation passage 17 for circulating the cooling air from the blower 15 provided in the instrument body 1 through the two ventilation towers 16.

Reference numeral 18 denotes a blow-out nozzle mounted on the upper end of the guide cylinder 10. Inside the steam nozzle, the steam flowing through the steam flow passage 14 and the air flowing through the forced ventilation passage 17 are provided. And are mixed and discharged into the room through the air outlet 20 having the guide piece 19.

A plurality of protrusions 21 are provided on the upper surface of the equipment body 1 to which the water supply tank 7 is attached, and between the equipment body 1 and the lower surface of the water supply tank 7, a central portion of the water supply tank 7 is provided. A small gap 22 that communicates with the air flow path 11 and allows air to flow by natural ventilation is formed.

Reference numeral 23 denotes an intake port formed on the side wall of the appliance body 1 for intake of indoor air by driving the blower 15. Reference numeral 24 denotes an operation unit, which is provided with an operation switch 25 and an automatic humidity control switch 26 that automatically maintains a constant humidity by ON / OFF control.

Next, the operation of this embodiment will be described. When the operation switch 25 is turned on to humidify the interior of the room, the heating heater-3 is energized to heat the heating tank 2 and generate steam from a certain amount of water stored inward. The generated steam automatically rises in the steam flow passage 14 of the guide cylinder 10 which is in air-tight communication.

On the other hand, at the same time when the heating heater 3 is energized, the blower 15 also starts to drive, and the air sucked from the intake port 23 is passed through the blower tower 16 to the steam flow passage 14 in the guide cylinder 10. It is supplied to the forced ventilation passage 17 on the outer periphery and is circulated in the forced ventilation passage 17 without coming into contact with the steam.

The steam and the blown air are mixed in the blow-out nozzle 18 at the upper end of the guide cylinder 10 and are vigorously discharged from the blow-out opening 20 into the room to humidify the inside of the blow-out nozzle 18. The steam mixes with the blown air to reduce the temperature and prevent the risk of burns, etc. due to careless contact with the steam.Because the steam mixes immediately before discharge, the steam is mixed. -It is possible to prevent the inconvenience that the generation of air bubbles is suppressed by the blown air, and to use the blown air to perform humidification in the room.

Further, due to the heating of the heating tank 2, the temperature around the heating tank 2 also rises to some extent, and in the small gap 22 between the instrument body 1 and the water supply tank 7, the temperature-increased air flows in the central air flow passage 11. Due to the upward printing, natural air is generated in which fresh air outside the instrument main body 1 is sucked into the small gap 22, and the air flows through the small gap 22 through the air flow path 11 to the outer periphery of the nozzle 18. A flow of air discharged into the room is further formed, which acts as an air-curtain that surrounds the inner and outer peripheries of the water supply tank 7, and particularly faces the bottom of the water supply tank 7 near the heating tank 2 and the steam flow passage 14. The inside of the water supply tank 7 can be surely insulated, and the heating of the water supply tank 7 raises the internal pressure, preventing the occurrence of problems such as humidification stoppage and water leakage due to abnormal water levels. I was able to use it with confidence Is.

Further, since this naturally ventilated air is discharged from the outer circumference of the blowing nozzle 18, the temperature of the steam can be lowered, and the stagnant steam around the blowing nozzle 18 can be carried as far as possible, and the steam can be conveyed. -It is possible to more effectively diffuse the aluminum into the room.
