Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a gas burner assembly, and
more particularly to a gas burner assembly having a burner core
sandwiched by a burner seat and a burner cap and having slits
defined through opposite sides of the burner core, wherein each of
the slits is deviated from and inclined relative to the radius of
the burner core such that an eddy effect occurs when the gas burner
is in use.
[0003] 2. Description of the Prior Art
[0004] Nowadays, the gas burner available on the market has slits
defined in the burner core and communicating with a gas path
defined in the burner seat. All of the slits are defined in a
manner such that when gas is filled in the path and the gas burner
is lit, the fire is substantially vertical to the gas burner.
Therefore, when a pot is placed on top of the gas burner, the pot
is evenly heated. As a result of this kind of slit design, it
requires a pretty long period of time until the pot reaches the
predetermined temperature. Also, the gas volume used to heat up the
pot is wasted due to the bad design of the conventional gas
burner.
[0005] To overcome the shortcomings, the present invention tends to
provide an improved gas burner assembly to mitigate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
an improved gas burner assembly to effectively consume gas and to
shorten heating time period.
[0007] In order to accomplish the objective, the gas burner
assembly of the present invention includes a burner seat, a burner
core and a burner cap sandwiching the burner core with the burner
seat. The burner core has slits defined through opposite sides of
the burner core and each slit is deviated to and inclined relative
to the radius of the burner core such that when the gas burner
assembly is in use after gas is filled in a path defined in the
burner seat, fire is directed to a direction and an eddy effect is
generated inside the gas burner assembly of the present invention.
Due to the eddy effect, the heating area is concentrated in the
center of the gas burner assembly. Thus temperature rising is fast
and gas consumed during the heating period is little.
[0008] In yet another objective of the present invention, each slit
is deviated from the radius for 30 degrees.
[0009] A further objective of the present invention is that each
slit is inclined relative to the radius for 25 degrees.
[0010] Other objects, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] With reference to FIGS. 1 and 2, it is noted that the gas
burner assembly in accordance with the present invention includes a
burner seat (10), a burner core (20) and a burner cap (30).
[0017] The burner seat (10) has a path (11) defined therein and
communicating with a gas source (not shown).
[0018] The burner core (20) has a circular shape and multiple slits
(21) defined through opposite sides of the burner core (20). The
burner cap (30) is provided with a cap portion (31) and a skirt
portion (32) extending downward from a bottom face of the cap
portion (31).
[0019] With reference to FIG. 3, it is noted that when the gas
burner assembly of the present invention is in assembly, the burner
core (20) is placed and rested on a top face of an inner periphery
defining the path (11) of the burner seat (10). Then the burner cap
(30) is placed on top of the burner seat (10) as well as the burner
core (20) to allow the skirt portion (32) to engage with a top face
of an outer periphery defining the path (11) and the cap portion
(31) to engage with a top periphery of the burner core (20). It is
noted that after the assembly of the gas burner assembly of the
present invention is finished, the path (11), an inner periphery of
the skirt portion (32) of the burner cap (30) and an outer
periphery of the burner core (20) form a space (A) in which gas
flows. Still, because the slits (21) are defined through opposite
sides of the burner core (20), the slits (21) communicate with the
space (A) defined by the inner periphery of the skirt portion (32)
of the burner cap (30) and the outer periphery of the burner core
(20).
[0020] Therefore, when the gas source starts supplying gas to the
path (11) of the burner seat (10), the space (A) communicating with
the path (11) is also filled with the gas, which allows the gas to
flow to the slits (21). The description above concerning the
structural relationship among components is substantially the same
as that of the conventional gas burner. However, due to the design
of the slits (21), the gas burner assembly of the present invention
is able to present much better efficiency than the conventional gas
burner.
[0021] With reference to FIGS. 4 and 5, it is noted that the top
plan view of the burner core (20) shows that each slit (21) is
defined in such a manner that a 30-degree deviation from a radius
of the burner core (20) exists. Also, each slit (21) is inclined
upward from the radius of the burner core (20) for 25 degrees. From
the accompanying drawings, each slit (21) is deviated in such a
manner that the gas is directed to a direction where an eddy flow
is generated inside the gas burner assembly of the present
invention.
[0022] When an eddy flow is generated inside the gas burner
assembly of the present invention, the fire as a result of the gas
provision is concentrated to a center of the burner core (20).
Furthermore, due to the upward inclination of the slits (21), the
fire is further concentrated in the center of the burner core (20).
As a result, a pot placed on top of the gas burner assembly of the
present invention is heated rapidly. Thus the volume of gas
consumption is little, yet the heating duration is reduced.
[0023] With reference to particularly FIG. 4, it is noted that a
counterclockwise gas flow in generated inside the burner core (20)
due to the arrangement of the slits (21). Thus when the gas inside
the gas burner assembly is lit, the fire is directed to, by the gas
flow, have a counterclockwise direction. In addition to the
counterclockwise direction of the fire as a result of the 30-degree
deviation of the slits (21) to the radius of the burner core (20),
the 25-degree inclination of the slits (21) concentrates the fire
to the center of the burner core (20).
[0024] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
