ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a steam generating device that has two side panels easily removed from the main body of the device and an inclined plate is located at the steam outlet for reducing water in the steam.
BACKGROUND OF THE INVENTION
A conventional sauna device for generating steam is shown in
FIGS. 1 and 2
and generally includes a rectangular main body
10
which has a horizontal plate
11
and a vertical plate
12
in the main body
10
. A steam generating tank
20
received in the space
101
below the horizontal plate
11
in the main body
10
and a steam outlet tube
21
is retained in a groove
111
defined in the horizontal plate
11
. The vertical plate
12
extends from the horizontal plate
11
such that an electromagnetic switch and a circuit plate (not shown) are respectively received in two partitions
102
,
103
separated by the vertical plate
12
. A water inlet tube
22
and a water outlet tube
24
respectively extend from the tank
20
, and a steam outlet tube
21
extends from a top of the tank
20
. A heater
23
is inserted into the tank
20
and a temperature gauge
25
is located at an underside of the tank
20
. A wave release plate
26
is located besides the temperature gauge
25
to eliminate the affection of the water waves hitting on the temperature gauge
25
. The maintenance for the device is inconvenient because if the electromagnetic switch and the circuit plate are to be taken out from the main body
10
, the whole main body
10
has to be removed from the wall and a top panel
14
is disengaged from the main body
10
to access the electromagnetic switch and the circuit plate. If the tank
20
is to be fixed, a side panel
13
is to be removed. The steam contains a lot of water particles when it goes out from the steam outlet tube
21
and the water particles tend to be condensed and elongate the period required to generate enough steam.
The present invention intends to provide a steam generating device that is easily to proceed maintenance processes.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a steam generating device and comprises a main body having two end plates connected two ends of the main body. Each of the end plates has an extension portion which is higher than the two sidewalls. Each of the extension portions of the two end plates has two notches defined in two sides thereof and two side panels each have two ends thereof respectively engaged with the two respective notches of the two end plates. A steam generating tank is received in the main body and has a water inlet tube, a water outlet tube and a steam outlet tube respectively extending from the tank and through the main body. A heater and a temperature gauge are connected to an inside of the tank.
The primary object of the present invention is to provide a sauna device that is easily to access the steam generating tank received in a main body.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
