Embodiment Construction

[0016]Referring to FIGS. 1 and 2, the steam generating device of the present invention comprises a metallic and elongate body 60, a U-shaped heating tube 70, a U-shaped pre-heat tube 10 and a connection tube 20. The body 60 and the heating tube 70 are similar to those disclosed in the conventional steam generating device. The body 60 has a waterway 61 defined longitudinally therein. An inlet 61 and an outlet 63 are respectively connected to two ends of the body 60 and communicate with the waterway 61. The U-shaped heating tube 70 is connected to the body 60 and located close to the waterway 61. Two free ends 71 of the heating tube 70 are exposed from the body 60 and connected to a power source which is not shown.

[0017]The body 60 has a recess 32 defined in an outside 30 thereof and the recess 32 is located close to the heating tube 70. The pre-heat tube 10 is received in the recess 32. The pre-heat tube 10 includes a U-shaped tubular body 11 which has the first end 12 and the second...

Abstract

A steam generating device includes a body having a waterway defined longitudinally therein, and an inlet and an outlet are respectively connected to the body and communicate with the waterway. A heating tube is connected to the body and located close to the waterway. A pre-heat tube is connected to outside of the body and has a first end for introducing cold water into the pre-heat tube and a second end connected to the inlet. The cold water is pre-heated in the pre-heat tube before entering the waterway so that the water in the waterway is easily transferred into steam.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a steam generating device, and more particularly, to a steam generating device having a pre-heat tube to increase the efficiency for generating steam.[0003]2. Description of the Prior Art[0004]A conventional steam generating device is cooperated with a water tank from which water is pumped into the steam generating device and heated to generate steam. The steam is ejected from an outlet to clean stains or kill germs or even to iron wrinkles of fabrics.[0005]The conventional steam generating device is shown in FIG. 5 and generally includes a body 60 which includes a waterway 61 defined longitudinally therein. An inlet 61 and an outlet 63 are respectively connected to the body 60 and communicate with the waterway 61. A U-shaped heating tube 70 is connected to the body 60 and located close to the waterway 61. Two free ends 71 of the heating tube 70 are exposed from the body 60 and connected...
