Description
BACKGROUND
[0001] 1. Field of Invention
[0002] The present invention relates to a mobile outdoor patio gas
fireplace.
[0003] 2. Description of Related Art
[0004] Generally, fireplaces are built into the interior of a house
and cannot be moved. If a fireplace is desired for outdoor use,
either a pit with burning firewood or a fixed outdoor fireplace
that is built as a fixture is commonly used. With either of these
designs, the fireplace cannot be moved and after they are used, it
is very dirty and messy to clean up the ash and soot from the
burned firewood.
[0005] Furthermore, both of these designs present a fire hazard
with the burning firewood. Sparks from the burning firewood or
burning cinders may be blown afloat by winds or activities around
the fireplace and ignite surrounding flammable materials, such as
other nearby firewood, trees, bushes, dry grass, clothing, paper,
wooden patio furniture, and wooden deck. In addition, starting a
fire in either of these fireplaces is difficult and dangerous.
Generally a match or a lighter is used to light flammable materials
such as paper and lighting fuel to start the fire and set the
firewood burning. This may require several attempts, particularly
if there is wind blowing or if the firewood is damp. With these
conventional fireplaces, several dangerous small ignitions means,
such as matches, lighter, paper, and lighter fluid, are present
around the fireplace. These things present a fire hazard,
particularly if children are around and can reach them.
[0006] After these conventional fireplaces have been used, the
flame must be put out by sure mean to ensure that the firewood do
not reignite from residual heat. Often, water is used as an
economical and safe way to put out the fire. However, once the fire
is extinguished by water, the fireplace cannot be reused until the
water is dried. This may take several hours, if not days.
[0007] As shown above, the conventional outdoor fireplace has
several drawbacks. The conventional outdoor fireplaces are
difficult and dangerous to use and are difficult to clean after
they are used. In addition, after the fire is extinguished, the
outdoor fireplace may not be used for a length of time.
SUMMARY OF THE INVENTION
[0008] The present invention is a mobile outdoor patio gas
fireplace that can be moved to any desired location and is safe and
easy to use. The present invention burns clean and does not require
any cleaning after it is used. Furthermore, the present invention
may be immediately reignited for use after it is turned off. The
preferred embodiment of the present invention comprises of a
housing enclosing a propane tank with hoses that direct the fuel in
the propane tank through a regulator with a small portion directed
to a pilot which is ignited by a ignitor and the majority of the
fuel directed through an adjustable gas valve and through a mixing
chamber to a burner within the housing, with the entire assembly
set on movable wheels.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 shows the preferred embodiment of the present
invention.
[0010] FIG. 2 shows the interior assembly of the preferred
embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] The preferred embodiment of the mobile outdoor patio gas
fireplace comprises of a housing 10 with an upper compartment and a
lower compartment attached to a set of wheels 13 allowing the
housing 10 to be freely moved to any desired location. The walls of
the upper compartment of the housing 10 are perforated and may be
in the form of a wire mesh 11. Enclosed within said lower
compartment of the housing 10 is a propane tank 1 containing
propane fuel removably attached to and located at the bottom of the
lower compartment of the housing 10. Attached to said propane tank
1 is a regulator 2 with an inlet and an outlet which will regulate
the flow of the fuel once the fuel is released form the propane
tank 1. An inlet hose 3 is attached to the outlet of the regulator
2 to direct the fuel to an adjustable gas valve 5. A small amount
of fuel is directed to a pilot 6 which is ignited by an ignitor 7.
Majority of the fuel is directed through the adjustable gas valve 5
to a mixing chamber 8 to be mixed with outside air and then
directed through the burner 9 located in the upper compartment of
the housing 10 to be ignited by the small flame at the pilot 6 and
burned. Surrounding the burner 9 may be placed gas logs 12 to
assist in radiating the heat and enhance the visual appeal of the
flame.
[0012] After the mobile outdoor patio gas fireplace is moved to the
desired location, the valve on the propane tank 1 containing the
propane fuel is opened to release the fuel from the propane tank 1
through a regulator 2. An inlet hose 3 directs the fuel exiting
from the regulator 2 to an adjustable gas valve 5. When the
adjustable gas valve 5 is opened by depressed it the
electromagnetic valve 4 is closed and a small amount of the fuel is
released to the pilot 6. When the ignitor 7 is depressed a spark is
generated at the pilot 6 and ignites the fuel. A small flame is
generated at the pilot 6 which in turn activates the electromagnet
in the electromagnetic valve 4 and retains the electromagnetic
valve 4 in the closed position and the adjustable gas valve 5 in
the open position to allow a continuous flow of fuel to the pilot
6. Majority of the fuel will flow through the adjustable gas valve
5 into a mixing chamber 8 to be mixed with the outside air to
create a combustible mixture. This combustible mixture is directed
through a burner 9 located in the upper compartment of the housing
10 which is then ignited by the small flame at the pilot 6 and
burned. Gas logs 12 may be placed around and/or on top of the
burner 9 to radiate the heat and increase the aesthetic appeal of
the flame.
[0013] If the flame at the burner 9 is distinguished by wind, the
small flame at the pilot 6 will immediately reignite the fuel
exiting from the burner 9 and continue the combustion. This will
prevent the flame at the burner 9 from being extinguished
unintentionally. If the small flame at the pilot 6 is extinguished,
the electromagnet will lose its magnetic property and will release
the electromagnetic valve 4 to its open position and close
adjustable gas valve 5 thereby ceasing the flow of fuel from the
propane tank 1. This will prevent accidental leakage of the fuel
and extinguish the flame at the burner 9.
[0014] The mobile outdoor patio gas fireplace may be shut off by
closing the adjustable gas valve 5 and ceasing the flow of fuel to
the pilot 6 and the burner 9. After the mobile outdoor patio gas
fireplace is shut off, it may be immediately reignited by simply
repeating the simple procedure to turn on the mobile outdoor patio
gas fireplace as described above.
[0015] The mobile outdoor patio gas fireplace can be moved to any
desired location and is safe and easy to use. The present invention
burns clean and does not require any cleaning after it is used.
Furthermore, the present invention may be immediately reignited for
use after it is turned off.
