A pipe condensation water passage 221 is formed between the steam supply pipe 210 and the condensate discharge pipe 220 to introduce condensate generated in the steam inlet space 110 and discharge the condensate discharge lake 320 to be described later. .

In addition, the outer surface of the double pipe 200 is preferably equipped with a handle 230 to easily grip the steam sprayer body 100, the handle 230 is to be mounted to the steam sprayer body 100 It may be, one side of the steam injector body 100, the other side may be mounted to the double pipe 200, of course.

The double pipe 200 is connected to the double lake 300 for supplying steam generated from the boiler to the double pipe 200, and discharges the condensed water flowing into the double pipe 200. Here, the double lake 300 has a dual structure in which the steam supply lake 310 and the condensate discharge lake 320 are disposed outside the steam supply lake 310. In addition, the double lake 300 is preferably provided with a Teflon material that can be flexibly bent.

That is, the lake steam flow passage 311 is formed in the steam supply lake 310 to supply the steam generated from the boiler to the steam supply pipe 220, the steam supply lake 310 and the condensed water discharge lake The lake condensation water flow passage 321 is formed between the 320 and the condensed water discharged through the pipe condensed water flow passage 221 is discharged to the condensate discharge pipe.

Here, the steam supply lake 310 and the condensate water discharge water 320 of the double lake 300 is connected to the steam supply pipe 410 and the condensate water discharge pipe 420, respectively, to introduce the steam supplied from the boiler and the condensate discharge pipe Although it may be configured to discharge the condensate flowing from the 220 to the condensate discharge pipe 420, as shown in Figure 4, the nipple assembly 400 has been filed and registered by the applicant (utility model registration 346109 It is preferable to easily connect the steam supply lake 310 and the condensed water discharge lake 320 of the double lake 300 to the steam supply pipe 410 and the condensed water discharge pipe 420 by using a).
