本発明は蒸気発生装置に関するもので、極めて

ギー型の蒸気発生装置を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam generator, and provides a resource-saving and energy-saving steam generator that can efficiently generate steam in an extremely short time and with relatively less energy than conventional ones. This is what we provide.
近年、加湿器，スチームアイロン，蒸気吸入

連製品が健康用品機器ブームにのり多く開発され
ている。 In recent years, there has been active development of devices that utilize steam generators that vaporize liquid in a short time, such as humidifiers, steam irons, steam inhalers, kerosene gasifiers, etc., and there are many humidifiers, Inhalers, steam ovens, kerosene gasification combustors, etc. have been well received. Among these, humidifiers and inhalers are effective for bronchitis and asthma patients, so recently many products related to these have been developed as part of the health equipment boom.

沸騰すると蒸気は気化室５から蒸気の噴出口６を

を経て、蒸気とともに９のごとく噴霧される。 However, as shown in Fig. 1, conventional inhalers have a structure in which water is injected into the main body 1 of the inhaler from a liquid inlet 2, and a specified amount of water 3 is heated by a sheathed heater 4 when the power is turned on. Yes, a power supply of 400 to 1KW is usually required for 300 to 400ml of water, and the time to generate steam is usually 7 minutes in summer and 10 to 10 minutes in winter.
The drawback was that it took 15 minutes. Note that when the water 3 boils, steam is ejected from the vaporization chamber 5 through the steam outlet 6, and at this time, the chemical solution 7 flows into the chemical solution introduction pipe 8.
After that, it is sprayed together with steam as shown in 9.

た。 This conventional device requires a considerable amount of time to add water and generate steam, and it is also difficult to adjust the steam temperature, which remains constant even if used for a short time unless a certain specified amount of water is added. Most of the sheathed heaters 4 do not generate a large amount of water vapor, and the sheathed heater 4 radiates a large amount of heat to the floor surface, and the main body 1 is often provided with heat radiation holes 5'. Therefore, sheathed heater 4
The energy use efficiency was extremely poor.
一方加湿器は夏期のクーラー使用時の乾燥対策
や冬期のFF式暖房器具使用時の加湿対策として、
クーラーおよびFF式暖房器具の成長とともに大
きく成長した製品である。 On the other hand, humidifiers are used as a countermeasure against dryness when using an air conditioner in the summer, and as a countermeasure against humidification when using an FF heater in the winter.
This is a product that has grown significantly along with the growth of coolers and FF heating equipment.

加湿器は市場で余り好評でない。 There are two types of humidifiers: ultrasonic type and heating type. However, like inhalers, heating type humidifiers take a long time to generate water vapor and are uneconomical from the viewpoint of energy efficiency. Because of this, it is not being used much. On the other hand, the ultrasonic humidifier is a widely used method, but what is generated from an ultrasonic humidifier is not water vapor but atomized water droplets with a particle size of 5 to 30 μm, so it is visually difficult to turn on the power. Although it appears that water vapor is generated at the same time, it takes time for the water droplets to evaporate into water vapor. By the way, the water vapor generated by an inhaler can reach the lungs, but the atomized water droplets of 5 to 30 μm generated by an ultrasonic humidifier are absorbed by the organs and do not reach the lungs, so from a health perspective, it is extremely dangerous. Sonic humidifiers are not very popular in the market.

を更に低下させることになる。 On the other hand, FF oil hot air fans and indoor air supply/exhaust type oil hot air fans have a built-in liquid vaporizer that vaporizes kerosene. This vaporizer uses a sheathed heater or a PTC thermosister as a heating element, and the basic structure of the heat conduction of the kerosene vaporizer is essentially the configuration shown in Figure 1. ) is a method of vaporizing kerosene by supplying a fixed amount of kerosene to the inner wall surface of the vaporizer. In this conventional method, the heat capacity of the heating element is inefficient in utilizing the sensible heat and latent heat required to vaporize kerosene, and it usually takes 3 to 6 minutes from the start of electricity supply until the kerosene is vaporized. Furthermore, since air is sent to the vaporization chamber for premixing, tar accumulates in the vaporization chamber, further reducing thermal efficiency.

This is an expandable steam generator. Hereinafter, the present invention will be explained in detail with reference to Examples.

着脱により容易に行える。 An inner wall 12 having a thermally sprayed coating layer 22 is provided on the inner wall surface of the vaporizer 11, and a heating element 13 having the thermally sprayed coating layer 21 is fixed in a hollow state to the center of the vaporizer 11 by a heating element spacer 14. There is. The vaporizer 11 is provided with a liquid supply port 15, a condensed liquid recovery port 16, and a vaporized vapor spout port 17, respectively, and the liquid 20 stored in the liquid tank 18 is supplied to the supply pump 19 via a supply pipe 27. The required amount is supplied to the vaporizer 11, and the thermal spray coating layer 2 is applied to the surface of the heating element 13 or the inner wall surface 22 of the vaporizer 11.
The liquid is instantaneously vaporized on the surfaces of 1 and 22, and the vaporized vapor is vigorously ejected from the vapor outlet 17. Further, during the initial use of the vaporizer 11 and after the power is turned off, vaporized vapor, that is, excess vapor and condensed liquid, are returned to the liquid storage tank 18 through the recovery port 16. Energy for the heating element 13 is supplied by an external power source through an electrical terminal 23. The interior of the vaporizer 11 can be easily inspected by attaching and detaching the back cover 24.
本実施例の特徴は第２図，第３図から理解でき

し、同時に気化ガスの逸散も改善させる。 As can be understood from FIGS. 2 and 3, the feature of this embodiment is that a heat generating element 13 is provided inside the vaporizer 11 to improve the efficiency of heat generation energy. That is, this embodiment has an extremely compact structure and has porous thermal spray coating layers 21 and 22 on the inner wall surfaces of the heating element 13 and the vaporizer 11 as shown in FIGS. 2 and 3 in order to instantaneously generate steam. This improves the wettability of the liquid, expands the liquid vaporization surface and heat exchange area, and at the same time improves the dissipation of vaporized gas.

It can be made lighter and has significantly improved energy efficiency.

画期的効果がみとめられた。 In particular, when kerosene is vaporized using the configuration shown in FIGS. 2 and 3, not only can the vaporizer 11 be made smaller, lighter, and more energy-saving, but the temperature of the heating element 13 can be raised to a higher temperature. (250 to 400°C), an epoch-making effect has been found in that almost no tar is generated.
