Abstract

PROBLEM TO BE SOLVED: To easily apply a hydrophilic treatment to the surface of a vaporizing chamber and improve a productivity by arranging an evaporating plate with a hydrophilic treatment applied to its surface in the vaporizing chamber formed on a base. SOLUTION: A base 8 formed integrally with a vaporizing chamber 7 is heated by a heater 9 and cast by using a die-cast aluminium material. The upper opening of the vaporizing chamber 7 is covered with a cover body 10. This cover body 10 is water-tightly connected to the base 8 through a silicone seal member. A tank 11 for storing water to be supplied to the vaporizing chamber 7 is provided above the base 8 so that water is dropped to the vaporizing chamber 7 from a nozzle 12. In this case, an evaporating plate 14 with a hydrophilic film 13 formed on its surface is attached to the vaporizing chamber 7 to improve the vaporization of water. The evaporating plate is attached by caulking an attaching part 15 protruding on the base 8. The end part of the attaching part is formed in a spherical shape so that water dropped from the nozzle 12 easily scatters.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) As shown in FIGS. 1 and 2, a base 8 integrally formed with a vaporizing chamber 7 is heated by a heater 9 and formed by casting using an aluminum material for die casting. The upper opening of the vaporizing chamber 7 is covered with a lid 10 and is formed by casting from the same material as the base 8 using die-cast aluminum, and is sealed to the honey by a silicone paste sealing member (not shown). Thus, the base 8 is formed.

A tank 11 for storing water to be supplied to the vaporizing chamber 7 is provided above the base 8, and water is dropped from the nozzle 12 to the vaporizing chamber 7. An evaporating plate 14 having a hydrophilic film 13 formed on the surface is attached to the inside of the vaporizing chamber 7 in order to enhance the vaporization of water. The evaporating plate 14 is provided in a plate shape with a good heat conductive material such as aluminum, and is attached at one place by an attachment portion 15 so that the lower surface is in contact with the surface of the vaporizing chamber 7.

The attachment portion 15 penetrates the evaporator plate 14 through a pin protruding from the surface of the vaporization chamber 7 so as to face the nozzle 12, and crushes and fixes the tip of the pin. And attachment part 1
The tip of 5 has a spherical shape so that water dropped from the nozzle 12 is easily broken and diffused.

The hydrophilic film 13 is formed, for example, by spraying an aqueous solution containing a surfactant on the surface of the evaporating plate 14 heated to about 200 ° C., thereby evaporating water to remove the surfactant. It can be formed by remaining on the surface. Alternatively, the hydrophilic film 13 can be formed by boiling the evaporating plate 14 in an aqueous solution of a water-soluble surfactant. The hydrophilic film 13 is preferably provided on the entire surface of the evaporating plate 14.

The operation of the above structure will be described. By attaching the evaporating plate 14 having the hydrophilic film 13 formed on the surface thereof to the vaporizing chamber 7, the heater 9 is not energized to heat the base 8, and This eliminates the need to cool the base 8 for performing the assembling work, thereby improving workability.

Further, since about 10 ml of an aqueous solution containing a hydrophilic material is not injected into the heated vaporization chamber 1 at a time to perform the hydrophilic treatment, the internal pressure of the vaporization chamber 7 increases instantaneously. Thus, good sealing performance can be secured without impairing the seal between the vaporizing chamber 7 and the lid 10.

Further, since the evaporating plate 14 is attached to the vaporizing chamber 7 at one place by the attachment portion 15, and a gap is provided between the evaporating plate 14 and the inner wall of the vaporizing chamber 7, abnormal noise is generated due to a difference in thermal expansion due to heating. Can be prevented.

(Embodiment 2) As shown in FIG.
6 is made of a thin film-shaped member, a hydrophilic film is formed on the surface thereof, and is attached by an attaching portion 15. The evaporating plate 16 is made of aluminum foil or the like having a very small specific heat with a thickness of about 0.05 mm to 0.2 mm. Other configurations are the same as those in the first embodiment.

According to the above configuration, the evaporating plate 1 is
6 can be efficiently transmitted, the water dropped on the evaporating plate 16 can be instantaneously evaporated by the heat of the base 8, and the temperature of the evaporating plate 16 is too low due to the dripping of water. Therefore, good steam can be efficiently and stably ejected. The evaporating plate 16
Is formed of a thin film-shaped member, the heat transfer to the base 8 can be further improved by providing a large number of attachment portions 15.

[0019]

According to the first aspect of the present invention, there is provided a base heated by a heater, a vaporization chamber formed in the base, and a tank for storing water supplied to the vaporization chamber. Since the evaporating plate whose surface has been subjected to hydrophilic treatment is provided in the vaporizing chamber, the surface of the vaporizing chamber can be subjected to hydrophilic treatment without heating the base, and good steam can be generated. At the same time, the iron can be assembled efficiently.

According to the second aspect of the present invention, since the evaporating plate is formed of a thin film-like member, the heat of the base is efficiently supplied to the evaporating plate to instantaneously evaporate the dropped water. And stable steam can be spouted out.

According to the third aspect of the present invention, there is provided a nozzle for dropping water from the tank to the vaporizing chamber, and an attaching portion for attaching the evaporating plate to the vaporizing chamber is provided opposite to the nozzle. Therefore, the water dropped from the nozzle can be broken at the attachment portion and diffused on the evaporating plate subjected to the hydrophilic treatment, and the water can be efficiently vaporized over a wide range of the evaporating plate.
