Benefits of technology

[0020]Preferably, the controller reduces a heating time of the heater as the pressure measured by the pressure sensor increases.
[0026]Preferably, the step of controlling includes reducing the water heating time as the measured pressure increases.

Problems solved by technology

When a high pressure is applied to the housing, if a steam discharge port for spraying steam is clogged with foreign matter, a pressure abnormally increases in the housing, thereby causing damage to the steam generator or explosion.
However, the conventional steam generator is not provided with a unit for detecting a pressure of the steam generator to automatically control an operation of the steam generator.
Accordingly, a user should manually check the pressure of the steam generator, thereby causing inconvenience to the user.

first embodiment

[0043]FIG. 2 illustrates a perspective view showing a steam generator according to the present invention.

[0044]Referring to FIG. 2, a steam generator 100 according to the first embodiment of the present invention includes the housing 20 in which water is contained and heated, the heater 40 for heating water in the housing 20 to generate steam, and a control unit 120 for controlling an operation of the heater 40 according to an inner pressure of the housing 20.

[0045]Specifically, the control unit 120 controls an operation of the steam generator 100, specifically, an operation of the heater 40 to be stopped when the inner pressure of the housing 20 is equal to or higher than a predetermined pressure.

[0046]That is, in the steam generator 100 according to the first embodiment, when the steam discharge port 60 of the housing 20 is clogged with foreign matter such as compounds of calcium and the inner pressure of the housing 20 increases to a predetermined pressure or more while the water...

second embodiment

[0060]FIG. 5 illustrates a perspective view of a steam generator according to the present invention.

[0061]Referring to FIG. 5, a steam generator 200 according to the second embodiment includes a control unit for controlling the heater 40 according to the inner pressure of the housing 20, the control unit having a pressure sensor 320 which measures the inner pressure of the housing 20 and a controller (not shown) which controls the operation of the heater 40 according to the pressure measured by the pressure sensor 320.

[0062]Specifically, the pressure sensor 320 is disposed at one side of the housing 20 and measures the inner pressure of the housing 20 to transfer the measured results to the controller. In this case, preferably, the pressure sensor 320 is installed at an upper portion of the housing 20. As for the reason, when the water in the housing 20 is boiled and the pressure increases, the steam is positioned at the upper portion of the housing 20. Accordingly, the pressure sen...

Abstract

A steam generator and a controlling method thereof are disclosed. The steam generator includes a housing for containing water, a heater for heating the water in the housing, and a control unit for controlling an operation of the heater according to an inner pressure of the housing.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application Nos. 10-2007-0078068, filed on Aug. 3, 2007 & 10-2007-0078069, filed on Aug. 3, 2007, which are hereby incorporated by reference in its entirety as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a steam generator, and more particularly to a steam generator capable of automatically controlling an on / off operation of a heater according to an inner pressure.[0004]2. Discussion of the Related Art[0005]Recently, clothes treating machines, for example, a washing machine, a dryer and a refresher, mostly include a steam generator for supplying steam to clothes.[0006]In the washing machine, the steam supplied in an initial period allows the clothes to quickly get wet, the steam supplied in a rinsing operation provides a sterilizing effect, and the steam supplied in a drying operation removes wrinkles from the ...
