The controller 70 may include a central processing unit 72, a memory 74, and a support circuit 76, as shown in FIG. The central processing unit 72 includes a water level sensor 28, a water supply pump 30, a steam generator 40, a temperature sensor 48, a directional control valve 57, an ion generator 58, 69 are controlled so as to be able to control the operation. The memory 74 may be connected to the central processing unit 72 and may be a computer-readable recording medium. The support circuit 76 may be coupled with the central processing unit 72 to support the typical operation of the processor and may include a cache, a power supply, a clock circuit, an input / output circuit, and a sub-configuration.

Hereinafter, the operation of the condensed water recovery system of the beauty steam injector according to the present invention will be described in detail with reference to FIG. 1 to FIG.

First, when the steam operation switch 14 is pressed while the power switch 12 is turned on, the steam injector operates the water supply pump 30 and the steam generator 40 by the controller 70. Steam is sprayed from the steam sprayer 50 after 7 to 10 seconds have passed since the steam operation switch 14 was pressed.

Next, the steam injector senses the water level, the steam temperature, and the steam jet range by the controller 70, and selectively operates or deactivates the water supply pump 30 and the steam generator 40 .

The condensed water formed when the steam is sprayed from the steam spraying unit 50 is collected in the nozzle accommodating unit 52 and the collected condensed water is supplied to the first water supply pipe 32 or the second water supply pipe 34).

That is, when the controller 70 controls the direction switching valve 57 to send the condensed water to the first return pipe 56a, it is returned to the first water supply pipe 32 located behind the water supply pump 32, When the condensed water is sent to the pipe 56b, it is recovered to the second water supply pipe 34 in front of the water supply pump 34.

At this time, the diameters of the first and second return pipes 56a and 56b are relatively larger than the diameters of the first and second water supply pipes 32 and 34 so that the first and second return pipes 56a and 56b The condensed water is easily sucked into the first and second water supply pipes 32 and 34 and recovered.

Although a preferred embodiment of the condensate recovery system for a beauty steam injector according to the present invention has been described above, various modifications may be made by those skilled in the art, Can not be understood individually from the technical constitution and can be understood as belonging to the claims of the present invention as a matter of course.
