Instantaneous steam boiler

Abstract

The present invention relates to an instantaneous steam boiler generating steam in a steam cleaner, a steam-vacuum cleaner, a steam iron, etc. The instantaneous steam boiler has a substantially short traveling path of water against the formation of fur by insertedly molding a separate flow tube while being in contact with a U-shaped heater.

1 . An instantaneous steam boiler, comprising:
 a heater;   a flow tube with a water inlet and a steam outlet; and   a body embedded in a manner to expose ports of the heater and the water inlet and the steam outlet of the flow tube.   
   
   
       2 . The instantaneous steam boiler according to  claim 1 , wherein the flow tube is embedded in the body while being in contact with the heater. 
   
   
       3 . The instantaneous steam boiler according to  claim 2 , wherein the body is molded with the heater and the flow tube already inserted, and the flow tube is formed into a U-shape. 
   
   
       4 . The instantaneous steam boiler according to  claim 1 , wherein the flow tube is made out of a copper material.
