BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a gas burner device and more particularly, to a
gas burner system, which facilitates operation and flame control.
2. Description of the Related Art
[0002] Commercial gas burner apparatus, such as gas ranges and barbecue stoves, commonly
use a piezoelectric igniter for ignition. A piezoelectric igniter generates an electric
potential in response to applied mechanical stress for causing discharge of sparks
for burning a fuel mixture.
[0003] Because a piezoelectric igniter is driven to achieve ignition manually by means of
rotating a cock, the operation of a gas burner apparatus using a piezoelectric igniter
is inconvenient to operate. Further, during the use of a gas burner apparatus from
the stage of fuel gas supply to the stage of conversion of fuel gas into thermal energy,
fuel gas control and regulation procedure performs the major part. The aforesaid cock
provides a fuel gas flow rate regulating function. However, because the cock must
be rotated by hand, it is difficult to achieve the desired throttle effect accurately.
This problem is insignificant to the application of a gas range in cooking foods.
However, the level of attainment (flame and time control) is quite important when
using a barbecue stove or grill to roast meat. The control of the level of attainment
is subject to accurate flowrate control. Inaccurate flowrate control results in unstable
control of the level of attainment, and the quality of each roasted foods will be
different.
SUMMARY OF THE INVENTION
[0004] The present invention has been accomplished under the circumstances in view.
[0005] It is therefore the main object of the present invention to provide an electrically
controlled gas burner system, which facilitates operation and accurate control of
the level of attainment.
[0006] To achieve this and other objects of the present invention, the gas burner system
comprises a power supply device, at least one gas burner, at least one gas valve for

one gas valve subject to the control signal received from the microprocessor, at least
one ignition induction electrode corresponding to the at least one gas burner in number
and respectively located on the at least one gas burner at one side, and at least
one igniter and inductor combination device for providing a high voltage current to
the at least one ignition induction electrode, subject to the control signal received
from the microprocessor, to cause the at least one ignition induction electrode to
discharge sparks for burning the discharged fuel mixture so that the at least one
igniter and inductor combination device stops from providing the high voltage current
when received a feedback flame signal from the ignition induction electrode and sending
the feedback signal to the microprocessor.
[0007] In an alternate form of the present invention, the gas burner system comprises a
power supply device, a plurality of gas burners, a plurality of gas valves each controlling
the fuel gas passage of one associating gas burner, a control device having an operating
device for giving a command signal, a microprocessor, which receives the command signal
from the operating device and runs subject to the received command signal and then

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0010] Referring to FIGS. 1 and 1A, a gas burner system
10 in accordance with a first embodiment of the present invention is shown comprising:
a power supply device 12, which provides the gas burner system 10 with the necessary working voltage;
a burner 14, which enables a fuel gas to be fully mixed with air for combustion;
a gas valve 16, which controls the passage (the fuel gas passage) through which a fuel gas is supplied
to the burner 14;
an operating device 18, which is one of the main input devices of the gas burner system 10 for the inputting of an external command, comprising a power switch PB1 adapted for switching on/off power supply, a flame switch PB2 adapted for heating mode control, a temperature-setting switch PB3 adapted for setting constant temperature mode control, a timer shutdown switch PB4 adapted for shutting down the system at the set time, an upward adjustment switch
PB5 and a downward adjustment switch PB6 adapted for adjusting the flame, temperature and time upwards/downwards respectively,
and a lamp switch PB7 adapted for switching on/off a light source 44;
a microprocessor 20 adapted to receive a command from the operating device 18 and to run subject to the received command; and
a remote control device 22, which is one of the input devices of the gas burner system 10 for the inputting of an external command for power supply on/off, heating mode, constant
temperature setting and shutdown operation controls as well as on/off controls of
the light source 44.
[0011] The remote control device
22 can be a RF (radio frequency) or IR (infrared) remote control device, comprising
a transmitter
22a for transmitting a data code and a receiver
22b for receiving and decoding the data code from the transmitter
22a and sending the decoded data to the microprocessor
20.
[0012] According to the embodiment shown in FIG. 1, the gas burner system
10 is operable through the wired operating device
18 or the wireless remote control device
22. The gas burner system
10 can be configured to provide only one input device, i.e., the wired operating device
18 or wireless remote control device
22. Further, a touch control device (not shown) may be used to substitute for the aforesaid
operating device
18. The touch control device comprises a touch control IC, and a touch panel adapted
for receiving input signal from a touch tip (finger or plastic pen nib) to substitute
for a mechanical keypad. Therefore, in the present invention, the definition of the
operating device includes a remote control device and a touch control device, and
should not limited to the operating device
18 shown in the drawings.
[0013] The gas burner system
10 further comprises:
a valve control device 24, which receives an inputted control signal from the microprocessor to switch the gas
valve 16, thereby closing/opening the fuel gas passage; and
a display device 26, which is controlled by the microprocessor 20 to display data including flame, temperature,
timer shutdown time and fuel level. The display device 26 can be a LCD or LED display device. When a LCD display device is sued, the display
device 26 can be modularized with the aforesaid touch control device, forming a touch panel.
[0014] The aforesaid operating device
18, microprocessor
20, remote control device
22, valve control device
24 and display device
26 constitute a main control device
28 of the gas burner system
10.
[0015] The gas burner system
10 further comprises:
an ignition induction electrode 30, which is disposed at one side of the gas valve 14 for sparks discharging and flame induction, and may be substituted by an ignition
electrode and an induction electrode that are adapted for sparks discharging and flame
induction respectively; and
an igniter and inductor combination device 32.
[0016] When the microprocessor
20 received an "On" command signal from the power switch
PB1, it adds a control signal to the valve control device
24 and the igniter
32, causing the valve control device
24 to open the gas valve
16 for enabling a fuel gas to be discharged to the gas burner
14 and simultaneously causing the igniter
32 to provide a high voltage current to the ignition induction electrode
30 for causing the ignition induction electrode
30 to discharge sparks so that the fuel mixture of the fuel gas that is discharged from
the gas burner
14 and mixed with air is burned to produce a flame. When a flame is produced, the ignition
induction electrode
30 feeds back the detected flame signal to the igniter and inductor combination device
32, causing the igniter and inductor combination device
32 to stop from discharging power (igniting). At the same time, the flame signal is
inputted into the microprocessor
20 through the igniter and inductor combination device
32. If flame ignition is failed, the microprocessor
20 drives the igniter and inductor combination device
32 to keep discharging a high voltage for several seconds, and then cuts off the circuit
from the valve control device
24 to switch off the gas valve
16 and to stop the supply of the fuel gas when receives no flame signal, returning to
a standby mode. This type of igniter and inductor combination device
32 is commonly used in the gas burner of a conventional water heater. With respect to
the technical content, please refer to Taiwan Utility Model No.
143956.
[0017] The gas burner system
10 further comprises:
a temperature sensor 34, which can be a thermoresistor or any suitable temperature sensing device installed
in the gas burner system 10 at a location where the temperature is to be detected, and adapted to detect the
surrounding temperature and to add the detected temperature signal to the microprocessor
20 so that the microprocessor 20 can control the operation of the valve control device 24 in driving the gas valve 16 to regulate the fuel gas flowrate subject to the temperature data received from the
temperature sensor 34, achieving temperature control;
a fuel gas indicator 36, which comprises a pressure switch 42 electrically connected with the microprocessor 20 and, which is electrically inducted to output a control signal to the microprocessor
20 when the fuel gas pressure dropped below a predetermined low level, causing a fuel
low sign or the word of fuel low to be displayed on the display device 26; and
a lighting device 38, which comprises a light source 44 adapted for providing illumination at night. The lighting device 38 is controlled by the microprocessor 20 to switch on/off the light source 44 subject to the signal from the lamp switch PB7. Further, the light source 44 can be a lamp tube or lamp bulb.
[0018] The aforesaid gas valve
16, as shown in FIGS. 10 and 11, comprises a valve housing
50, a first electromagnetic valve
70a and a second electromagnetic valve
70b. The valve housing
50 has a fuel gas passage
52, and a first mounting hole
54 and a second mounting hole
56 respectively disposed in communication with the fuel gas passage
52. The fuel gas passage
52 has an inlet
58 and an outlet
60 arranged on the same central axis
66. An inlet connector
62 and an outlet connector
64 are respectively formed on the inlet
58 and the outlet
60 for the connection of a respective fuel gas tube (not shown) by means of, for example,
a screw joint. The fuel gas tube that is installed in the inlet connector
62 is connected to a fuel gas source (not shown). The fuel gas tube that is installed
in the outlet connector
64 is connected to the gas burner
14. The first electromagnetic valve
70a and the second electromagnetic valve
70b are respectively installed in the first mounting hole
54 and the second mounting hole
56, and respectively controlled to close/open the fuel gas passage
52.
[0019] The first electromagnetic valve
70a and the second electromagnetic valve
70b are same in structure. For letting the first electromagnetic valve
70a and the second electromagnetic valve
70b cause different throttle effects relative to the fuel gas passage
52, the diameter of the gas outlet
72a of the first electromagnetic valve
70a can be smaller or greater than the gas outlet
72b of the second electromagnetic valve
70b, or alternatively, as shown in FIG. 11, a first bushing
74a and a second bushing
74b are respectively mounted in the gas outlet
72a of the first electromagnetic valve
70a and the gas outlet
72b of the second electromagnetic valve
70b and the diameter of the hole
76b of the second bushing
74b is greater than the diameter of the hole
76a of the first bushing
74a. Thus, by means of controlling the first electromagnetic valve
70a and the second electromagnetic valve
70b to operate separately and to operate simultaneously, three throttle control modes
can be selectively done.
[0020] Simply speaking, when the valve block
78a of the first electromagnetic valve
70a is opened, only a small amount of fuel gas is allowed to flow through the gas inlet
80a into the fuel gas passage
82a, and then to flow out of the hole
76a of the first bushing
74a to the outside of the fuel gas passage
52 via the outlet
60 for further combustion. When the valve block
78b of the second electromagnetic valve
70b is opened, a medium amount of fuel gas is allowed to flow through gas inlet
80b into the fuel gas passage
82b, and then to flow out of the hole
76b of the second bushing
74b to the outside of the fuel gas passage
52 via the outlet
60 for further combustion. When the valve block
78a of the first electromagnetic valve
70a and the valve block
78b of the second electromagnetic valve
70b are simultaneously opened (see FIG. 12), a big amount of fuel gas is allowed to flow
into the fuel gas passage
82a through the gas inlets
80a and
80b, and then to flow out of the holes
76a and
76b to the outside of the fuel gas passage
52 via the outlet
60 for further combustion. By means of operating the related switches (buttons) of the
operating device
18, the flame of the gas burner system
10 is adjusted. According to this embodiment, the flame is adjustable in three steps.
Of course, by means of increasing the number of electromagnetic valves, the number
of flame adjustment steps is relatively increased. Further, the fuel gas passage
52 is not limited to one outlet
60. It can be made having a plurality of outlets
60. Further, the diameter of the hole
76b of the second bushing
74b can be made smaller than the diameter of the hole
76a of the first bushing
74a.
[0021] FIGS. 13 and 14 are similar to FIGS. 10 and 11, showing an alternate form of gas
valve. The gas valve
16c of this embodiment is substantially similar to the aforesaid gas valve
16 with the exception that the inlet connector
62a and outlet connector
64a at two sides of the valve housing
50a of the gas valve
16c have different designs and, the inlet
58a and outlet
60a are arranged at right angles. The other component parts of the gas valve
16c shown in FIGS. 13 and 14 are same as the corresponding component parts of the gas
valve
16 shown in FIGS. 10 and 11, and therefore like parts are indicated by like reference
signs. Further, the above description regarding to the gas valve
16 shown in FIGS. 10 and 11 is applicable to the gas valve
16c shown in FIGS. 13 and 14.
[0022] The invention is not limited to the aforesaid embodiments. Other modifications can
be made thereunto without departing from the spirit and scope of the invention. For
example, the combination of the gas burner
14 and ignition induction electrode
30 shown in FIG. 1 can be duplicated, forming a fuel gas system
10a having multiple gas burners
14 (see FIG. 2), or the combination of the gas burner
14, gas valve
16 and ignition induction electrode
30 shown in FIG. 1 can be duplicated, forming a fuel gas system
10b having multiple gas burners
14 (see FIG. 3). By means of increasing the number of gas burners, the heat energy produced
is relatively increased. In the gas burner system
10a shown in FIG. 2, the fuel gas passages of the multiple gas burners
14 are controlled by one gas valve
16. However, in the gas burner system
10b shown in FIG. 3, one respective gas valve
16 controls the fuel gas passage of one respective gas burner
14.
[0023] Further, the gas burner system
10c shown in FIG. 4 is a modification of the gas burner system
10b shown in FIG. 3 such that every gas burner
14 has a respective supplementary operating device
18c and supplementary display device
26c. According to this embodiment, the supplementary operating device
18c has only a power switch and flame switches for controlling the associating gas burner
14, and the supplementary display device
26c is for displaying the scale of the flame only. With respective to high-level functions
such as time setting, temperature setting and lighting controls, they must be controlled
through the control device
28.
[0024] Further, a side stove can be added to the gas burner system
10b shown in FIG. 3 for cooking foods. FIG. 5 illustrates a gas burner system
10d having a side stove
40. The side stove
40 is comprised of a gas burner
14a, a gas valve
16a, a supplementary control device
28a, an ignition induction electrode
30a and an igniter and inductor combination device
32a. The supplementary control device
28a comprises a supplementary operating device
18a, which comprises a power switch and flame switches, a supplementary microprocessor
20a, which receives a command signal from the supplementary operating device
18a and runs subject to the command signal received and then outputs a corresponding
control signal, a valve control device
24a, which receives the control signal from the supplementary microprocessor
20a and drives the gas valve
16a subject to the nature of the control signal received, and a supplementary display
device
26a, which is controlled by the supplementary microprocessor
20a to display the flame status.
[0025] FIG. 6 shows a gas burner system
10e made by simplifying the design shown in FIG. 1. This embodiment eliminates the remote
control device
22, temperature sensor
34, gas level indicator
36 and lighting device
38 shown in FIG. 1, and also eliminates the functions of temperature setting and time
setting from the main control device
20, and therefore this simple type gas burner system
10e has flame adjustment and flame scale display functions to fit a different requirement.
[0026] It is to be understood that the igniter and inductor combination device
32 and the control device
28 in the embodiments shown in FIGS. 1∼5 are independent modules. Actually, the igniter
and inductor combination device
32 can be incorporated into the main control device
28. According to the embodiment shown in FIG. 1B, the igniter and inductor combination
device
32 is incorporated into the main control device
28c, forming a control module having an igniter and inductor combination device.
[0027] Further, the combination of the gas burner
14, gas valve
16, control device
28 and ignition induction electrode
30 can be duplicated, providing a gas burner system
10f having multiple gas burners
14 (see FIG. 7) that provides an enhanced heat energy.
[0028] FIG. 7A shows a gas burner system
10F substantially similar to the embodiment shown in FIG. 7. According to this embodiment,
each control device
28d comprises an igniter and inductor combination device
32d, forming a control module having an igniter and inductor combination device.
[0029] FIG. 8 is a system block diagram of still another alternate form of the present invention.
According to this embodiment, the gas burner system
10g has all the technical characteristics of the gas burner system
10 shown in FIG. 1, and comprises further two gas burners
14d, two gas valves
16b, two ignition induction electrodes
30b and two supplementary control devices
28b. This embodiment further comprises a side stove
40 same as that shown in FIG. 5. According to this embodiment, each supplementary control
device
28b comprises a supplementary operating device
18b, which has a power switch and flame switches, a supplementary microprocessor
20b, which receives a command signal from the supplementary operating device
18b and runs subject to the common signal received and then outputs a corresponding control
signal, a valve control device
24b, which receives the control signal from the supplementary microprocessor
20b and drives the associated gas valve
16b subject to the nature of the control signal received, and a supplementary display
device
26b, which is controlled by the supplementary microprocessor
20b to display the flame status.
[0030] Similarly, the igniter and inductor combination device
32 can be incorporated in the control device
28, and each supplementary control device
28b can be made having an igniter and inductor combination device
32 and adapted for receiving a respective control signal from the microprocessor
20 and the supplementary microprocessor
20b.
[0031] FIG. 9 shows a gas burner system
10h in accordance with still another embodiment of the present invention. This embodiment
is substantially similar to the gas burner system
10g shown in FIG. 8 with the exception that this embodiment omits one combination of
gas burner
14 and gas valve
16 that is directly controlled by the control device
28.
[0032] FIG. 9A shows a gas burner system
10H modified from the embodiment shown in FIG. 9. This embodiment eliminates the igniter
and conductor combination device
32 from the aforesaid gas burner system
10h, however every supplementary control device
28e has an igniter and conductor combination device
32e for receiving the control signal from the associating supplementary microprocessor
20b. Further, the igniter and conductor combination device
32e of the side stove
40 shown in FIG. 9A is incorporated in the supplementary control device
28f, forming a part of the supplementary control device
28f.
[0033] A gas burner system made according to the present invention utilizes electronic control,
and therefore the operation is easy and, the flame level can be controlled accurately.
[0034] Further, the gas burner system has a display device for displaying the operation
status, including temperature, flame scale, timer shutdown time and fuel gas level.
[0035] Further, the gas burner system is provided with a remote control device so that a
user can switch on/off the system, regulate the flame level, set the temperature and
set the timer shutdown time at a distance.
[0036] Although particular embodiments of the invention have been described in detail for

departing from the spirit and scope of the invention. Accordingly, the invention is
