ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a vaporization apparatus, especially to a vaporization apparatus, wherein the heat energy can be directly transmitted from bottom of the base to the bottom of the heat-conducting fin plate, thus confining thermal energy.
BACKGROUND OF THE INVENTION
The prior art vapor generating apparatus is generally a heating tray within which water is deposited and heated. The water therein is boiled to vapor and used to sterilization.
As shown in
FIGS. 1 and 2
, a prior art vapor generating apparatus is composed of a base
1
a made of material with good thermal conductivity, an accommodation space
10
a
within the base
1
a
and a U-shaped heating pipe
11
a
arranged below the base
1
a
. The accommodation space
10
a
contains a plurality of thermal-conductive fin plates
12
a
, which facilitate the boiling of water in the accommodation space
10
a
. When using the vapor generating apparatus, water is put into the accommodation space
10
a
and then the heating pipe
11
a
is powered for heating. The temperature of the heating pipe
11
a
is raised and the heat generated by the heating pipe
11
a
is conducted to the sidewall
14
a
and the fin plates
12
a
through the bottom portion
13
a
of the base
1
a
. The water in the accommodation space
10
a
is heated to vaporization and the vapor can be used for sterilization.
However, the heat conducting medium provided by the bottom portion
13
a
and the sidewall
14
a
is not sufficient and the effect of the fin plate
12
a
is important. In prior art vapor generating apparatus, the heating pipe
11
a
is provided below the base
1
a
and the fin plate
12
a
is heated only after the thermal energy is transmitted from the bottom portion
13
a
through the base
1
a
. The effect of the fin plate
12
a
is influenced.
SUMMARY OF THE INVENTION
It is the first object of the present invention to provide a vaporization apparatus, wherein a heating pipe is completely or partially overlapped with the bottom side of the heat-conducting fin plate and the heat energy can be directly transmitted from bottom of the base to the bottom of the heat-conducting fin plate, thus confining thermal energy.
It is the first object of the present invention to provide a vaporization apparatus, wherein the contact area between a heating pipe and a base is increased.
To achieve the first object, the present invention provides a vaporization apparatus comprising a cover, a base, and a heating pipe. The base is arranged below the cover and assembled integrally with the cover. The base has an accommodation space therein and a heat-conducting fin plate is provided in the accommodation space. The heat-conducting fin plate has a bottom side connected to a bottom side of the base and the heating pipe is arranged below the base. The heating pipe is completely or partially overlapped with the bottom side of the heat-conducting fin plate. The heat energy generated by the heating pipe can be concentrated to the heat-conducting fin plate and water in the accommodation space can be rapidly heated.
To achieve the first object, the present invention provides a vaporization apparatus wherein the base thereof has a dent corresponding to the heat-conducting fin plate and the heating pipe is received within the dent.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
