Description

{DEVICE FOR GENERATING HUMIDITY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wetting generating device, and more particularly, to a wetting generating device for generating steam by operating an electric heater for controlling humidity in a corrosion testing machine.

In general, various methods for evaluating the corrosion resistance of stainless steel materials are known. Among them, there is a combined cycle corrosion test method for evaluating the atmospheric environment and in-water resistance through combination of salt spray, temperature and humidity cycle. The equipment used for these tests is referred to as a combined cycle corrosion test machine.

Humidity control is very important during operation of the combined cycle corrosion tester. Accordingly, a separate humidifying device for controlling the humidity during operation of the combined cycle corrosion tester is used.

Most of the humidifying devices use pure water or purified water, and a heating means such as an electric heater is provided therein to generate pure water or purified water supplied from outside to raise the temperature to 100 degrees or more. The steam thus generated is supplied to a combined cycle corrosion tester and used for humidity control.

However, when a water is used for cost reduction, a large amount of scale is generated in the inside of the wet generator by concentration of calcium (Ca), magnesium (Mg), and the like. The scale thus generated results in a malfunction of the water level sensor mounted inside the humidifier. Due to this, the humidifier needs periodic cleaning.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein, It is provided to inform.

Several methods for evaluating the corrosion resistance of stainless steel materials are known. Among them, there is a combined cycle corrosion test method for evaluating the atmospheric environment and in-water resistance through combination of salt spray, temperature and humidity cycle. The equipment used for such tests is referred to as a combined cycle corrosion test machine.

Humidity control during operation is very important especially for the combined cycle corrosion tester. Accordingly, a separate humidifying device for controlling the humidity during operation of the combined cycle corrosion tester is used. Most humidifying devices use pure water or purified water, and generate pure water or purified water supplied from outside using an electric heater or the like to generate steam by heating to 100 degrees or more. The steam thus generated is supplied to a combined cycle corrosion tester and used for humidity control.

However, when water or the like is used, a large amount of scale is generated by concentration of calcium (Ca), magnesium (Mg) or the like in the inside of the humidifier. Such a scale causes harmful results such as malfunction of the water level sensor . Thus, the wetting generator needs periodic cleaning. However, in the case of a conventional wet generator, the internal structure thereof is complicated and difficult to clean, and there has been a problem of a delay in cleaning time and an increase in cost.

The bar-shaped heating unit 131 (see FIG. 4) and the heating unit 133 (see FIG. 4) may have an integral structure.

4) may have a length corresponding to the depth of the accommodating space of the main body 110 such that when the cover 120 is engaged with the main body 110, the emblem heating unit 131 (See Fig. 4) is disposed at the lower end of the accommodation space of the main body 110. [

4) may be connected through a lower end of the bar-shaped heating unit 131 (see FIG. 4) and horizontally extended from the lower end of the receiving space of the main body 110. [

In addition, the electric heater 130 including the above-described bar type heating unit 131 (see FIG. 4) and the embroidery heating unit 133 (see FIG. 4) , 130 'are symmetrically arranged with respect to one another.

1) is fixed to the lower end of the main body 10 and the electric heater 20 (see FIG. 1) is formed in a spiral shape (or a spiral shape) Shape), it was difficult to clean scale and the like. However, in the present invention, the electric heater 130 (see FIG. 4) having a simple structure is used as described above. In particular, since the electric heater 130 is coupled to the lower end of the cover 120, The convenience of the cleaning operation can be greatly improved.

Referring to FIG. 2, an electrical connection terminal 126 may be provided on the cover 120.

The water level sensor 190 may further include a water level sensor 190 for sensing the level of water stored in the body 110 through the accommodation space 112 of the body 110.

Preferably, the water level sensor 190 may be disposed proximate to the water supply line 180 to sense the level of water stored within the body 110 and to control the amount of additional water supplied.

The receiving space 112 of the main body 110 should be partitioned into a space where the electric heaters 130 and 130 'are disposed and a space where the water level sensor 190 is disposed.

If the water stored in the main body 110 boils due to the heating action of the electric heaters 130 and 130 ', the bubbling phenomenon may occur, which may cause malfunction of the water level sensor 190 . Therefore, the bubbling prevention plate 140 is disposed between the space where the electric heaters 130 and 130 'are disposed and the space where the water level sensor 190 is disposed, thereby partitioning the space between them.

However, when the bubbling prevention plate 140 is fixedly coupled, the space in which the water level sensor 190 is disposed becomes narrow, which may cause inconvenience to a cleaning operation such as a scale. Therefore, in the present invention, the bubbling prevention plate 140 is configured to be attachable / detachable.

Accordingly, when the wet generator is operated to generate steam, the bubbling prevention plate 140 is mounted at the corresponding position, and during the cleaning operation for removing foreign substances such as scale, the bubbling prevention plate 140 is removed So that the inside of the main body 110 can be easily cleaned.

FIG. 5 is a view schematically showing a state in which the bubbling prevention plate is separated from the inside of the main body of the wetness generating device according to the embodiment of the present invention. Referring to FIG. 5, it can be seen that the bubbling prevention plate 140 is configured to be detachable in the vertical direction. As a specific example, the bubbling prevention plate 140 may be formed to be slidable in the vertical direction along a sliding path (not shown) provided in the body 110, but is not limited thereto. If it is a removable structure, it can be used without limitation.

Fig. 6 is an overall configuration diagram of a wetting generator according to an embodiment of the present invention.

6, the illustrated wetting generator includes a body 110, a cover 120, and an electric heater (not shown) coupled to the lower portion of the cover 120 and disposed in a space between the body 110 and the cover 120 130, 130 ', see FIG. 4). And a bubbling prevention plate 140 (see FIG. 5) that is detachably coupled to the inside of the main body 110 as described above.

The steam generated by heating the water stored in the main body 110 is supplied to the outside through the steam supply pipe 170. The steam is preferably supplied to a combined cycle corrosion tester (not shown)

An electrical connection terminal 126 and a connector line 127 are provided on the cover 120 and a protective case 129 may be further provided to prevent the electrical connection terminal 126 from being damaged or damaged.

In addition, on both sides of the upper portion of the cover 120, a handle (hereinafter, referred to as 'handle member 125') capable of being held by an operator can be further provided. The operator can easily open the main body 110 by lifting the cover 120 while grasping the handle member 125 provided on both sides of the cover 120. [

Referring to FIG. 7, the wet generator 200 shown in FIG. 1 includes a main body 210 and a cover 220, and electric heaters 230 and 230 'are coupled to a lower portion of the cover 220 , Which are the same as or similar to those of the above-described embodiment of the present invention, and redundant description will be omitted.

However, the wetting apparatus 200 shown in FIG. 7 differs from the above-described embodiment of the present invention in the coupling structure between the cover 220 and the main body 210.

That is, the cover 220 is hinged to the main body 210 and is rotatable in the direction of opening and closing the main body 210. At least one sealing member 222 may be provided at a contact portion between the main body 210 and the cover 220.

The upper end of the main body 210 is formed to be inclined. The cover 220 is tightly coupled to the upper end of the inclined main body 210.

Specifically, the other side 221a of the cover 220 is hingedly connected to the main body 210 so that the other side 221a extends downward. Therefore, the cover 220 can be brought into close contact with the main body 210 by the self weight of the cover 220, thereby improving the sealing effect.

As described above, according to the constitution and the function of the present invention, it is possible to improve the convenience of the cleaning work such as scaling as the wet generator for generating steam by operating the electric heater for controlling the humidity in the corrosion tester.

In addition, the bubbling preventing plate preventing malfunction of the level sensor due to bubbling occurring when water boils can be removed, thereby improving the convenience of the cleaning operation.

Further, the electric heater is fixed to a cover separated from the main body by being detached from the structure fixed to the main body, so that the main body can be cleaned easily through opening of the cover, and it is also effective to remove scales and the like attached to the electric heater.
