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 tie 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.

The remote control device 22 can be a RF (radio frequency) or IR (infrared) remote control device, comprising a transmitter 22 a for transmitting a data code and a receiver 22 b for receiving and decoding the data code from the transmitter 22 a and sending the decoded data to the microprocessor 20.
According to the embodiment shown in FIG. 1, the gas burner system 10 is operable ugh 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.
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.
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.
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.
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 3 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.
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.
The aforesaid gas valve 16, as shown in FIGS. 10 and 11, comprises a valve housing 50, a first electromagnetic valve 70 a and a second 20 electromagnetic valve 10 b. 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 70 and the second electromagnetic valve 70 b 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.
The first electromagnetic valve 70 a and the second electromagnetic valve 70 b are same in structure. For letting the first electromagnetic valve 70 a and the second electromagnetic valve 70 b cause different throttle effects relative to the fuel gas passage 52, the diameter of the gas outlet 72 a of the first electromagnetic valve 70 a can be smaller or greater than the gas outlet 72 b of the second electromagnetic valve 70 b, or alternatively, as shown in FIG. 11, a first bushing 74 a and a second bushing 74 b are respectively mounted in the gas outlet 72 a of the first electromagnetic valve 70 a and the gas outlet 72 b of the second electromagnetic valve 70 b and the diameter of the hole 76 b of the second bushing 74 b is greater than the diameter of the hole 76 a of the first bushing 74 a. Thus, by means of controlling the first electromagnetic valve 70 a and the second electromagnetic valve 70 b to operate separately and to operate simultaneously, three throttle control modes can be selectively done.
Simply speaking, we the valve block 78 a of the first electromagnetic valve 70 a is opened, only a small amount of fuel gas is allowed to flow through the gas inlet 80 a into the fuel gas passage 82 a, and then to flow out of the hole 76 a of the first bushing 74 a to the outside of the fuel gas passage 52 via the outlet 60 for further combustion. When the valve block 78 b of the second electromagnetic valve 70 b is opened, a medium amount of fuel gas is allowed to flow through gas inlet 80 b into the fuel gas passage 82 b, and then to flow out of the hole 76 b of the second bushing 74 b to the outside of the fuel gas passage 52 via the outlet 60 for further combustion. When the valve block 78 a of the first electromagnetic valve 70 a and the valve block 78 b of the second electromagnetic valve 70 b are simultaneously opened (see FIG. 12), a big amount of fuel gas is allowed to flow into the fuel gas passage 82 a through the gas inlets 80 a and 80 b, and then to flow out of the holes 76 a and 76 b 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 76 b of the second bushing 74 b can be made smaller than the diameter of the hole 76 a of the first bushing 74 a.
FIGS. 13 and 14 are similar to FIGS. 10 and 11, showing an alternate form of gas valve. The gas valve 16 c of this embodiment is substantially similar to the aforesaid gas valve 16 with the exception that the inlet connector 62 a and outlet connector 64 a at two sides of the valve housing 50 a of the gas valve 16 c have different designs and, the inlet 58 a and outlet 60 a are arranged at right angles. The other component parts of the gas valve 16 c 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 16 c shown in FIGS. 13 and 14.
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 10 a 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 10 b 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 10 a 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 10 b shown in FIG. 3, one respective gas valve 16 controls the fuel gas passage of one respective gas burner 14.
Further, the gas burner system 10 c shown in FIG. 4 is a modification of the gas burner system 10 b shown in FIG. 3 such that every gas burner 14 has a respective supplementary operating device 18 c and supplementary display device 26 c.
