Description

INFRARED RAY GAS BURNER
FIELD OF THE INVENTION
The present invention relates generally to a gas burner, and particularly to an improvement on the ignition system of a household infrared ray gas burner.
BACKGROUND OF THE INVENTION
With the improvement of people's living standards, gas utensils, such as home gas cooker, warmer and barbecue oven, have spread to millions of households; wherein, the infrared ray gas burner has been accepted by domestic customer, commercial user and industrial user, because it has obvious high performances on energy efficiency and environmental protection, cleanliness of health and safe and reliable. Since a larger relatively large primary air coefficient has been adopted by the infrared ray gas burner, and the burner will be normally ignited and combusted only after the air in the furnace chamber of the burner, which chamber is used for mixing burner gas with primary air and is fairly large, has been emptied, therefore, it is difficult to directly ignite the gas-air mixture escaping from a fire hole by pulse electrical sparkle or piezoelectric ceramic ignition, both of which are easy to produce deflagration when ignition, and generally the ignition is achieved by igniting the main burner via a start-up burner through an ignition nozzle. Meanwhile, for domestic infrared ray gas cooker, and specifically for built-in type cooker, considering the beauty of the cooker surface and sealing requirement, the ignition burner is installed outside the infrared main burner, such as the center, bottom and external of the burner outside burner, with adopting a certain elevation upward. Gas flows into the ignition support through the ignition nozzle and mixes with partial air, electric ignition sparkle ignite the mixed gas on the ignition support to form an ignition flame, and the ignition flame is fired into the main burner, so as to ignite the main burner. At present, the burners in the market have the following defects on ignition structure and operating mode:
1. In the way of igniting the burner from the outside of the burner by igniting on the external perimeter of the burner, its structural design must keep a certain gap between the burner and the disc or the cooker surface, otherwise, the main burner ignited by an ignition flame will be affected, but this structure obviously affects the appearance of the product, and makes the product be no vitality and no market value. In addition, the ignition flame is large, so the decorative sheet or the cooker surface around the burner will be blackened that obviously affects the appearance of the product, and at the same time, there is much incomplete combustion therein.
2. In the way of igniting the burner from outside flame by an ignition nozzle placed at the bottom of the burner, it needs a center channel to ignite the main burner. In the moment of igniting the start-up burner, flareback is likely to happen after the flame spurts and touches the ignition plate, which will burn in front of the start-up burner, and the transmission distance of the flame is not enough to reach the main fire hole or main fire plate, therefore resulting in misfire or deflagration.
3. In the way of igniting the burner from outside flame by an ignition nozzle placed at the bottom of the burner, it needs a center channel to ignite the main burner. Due to the limited diameter of the center channel, it has a certain obstruction against the transmission of the flame.
When the piping gas pressure is low, the ignition flame cannot overcome the resistance to reach the main fire hole, resulting in misfire. When the piping gas pressure is high, the air in the center channel is quickly removing by the smoke generated by the ignition flame, and then the transmission of the flam is limited due to lack of oxygen in the channel.
4. In the way of igniting the burner from outside flame by an ignition nozzle placed at the bottom of the burner, it needs a center channel to ignite the main burner.
Because the ignition center channel is small, the ignition flame is generally large and black and has obviously incomplete combustion, and the gas-air mixture of the main burner lags to reach the main ignition fire hole with low concentration; when ignition is not successfully achieved in the ignition moment, the ignition flame will be directed to the bottom of the burner, and due to the inertia of the flame, the ignition flame cannot stay on the surface or side face of the main ignition fire hole, and therefore cannot normally ignite the burner.
5. In the way of igniting the burner from outside flame by an ignition nozzle placed at the bottom of the burner, the structures of the ignition nozzle and the ignition support are more complex, so they are not easy to be installed at the bottom of the burner or in the narrow space of the center channel, and the reliability and precision of the installation are low, and therefore result in poor ignition performance of the product.
6. In the way of direct ignition through an ignition flame on the upper surface of the infrared ray combustion radiant panel, since the chamber volume of the infrared ray burner is large, it needs a long time for the gas-air mixture to extrude the original air in the chamber, and the concentration of the gas is low, so it is difficult to ignite and causes a low fire rate, especially when igniting by piezoelectric ceramics it is very difficult to achieve normal ignition.
Therefore, how to design and change the structure of the burner so as to improve the appearance and ignition reliability of the product becomes a tough technique problem in the product design of infrared ray gas burner for domestic and commercial use, especially in the design of built-in type infrared ray cooker at present.
SUMMARY OF THE INVENTION
The object of the invention is to improve the ignition structure of a burner and provide a new ignition integrated structure of infrared ray burner, so that the product will have beautiful appearance, high ignition reliability of burner, good combustion performance, simple and credible structure, and will be easy to install and adapted to a wide range of gas.
The technical solution of the present invention is as follows:
An infrared ray gas burner consists of an ignition valve 1, a nozzle 2, an ejector 3, a furnace chamber 4, a porous combustion radiant panel 5 and an ignition needle 6, an ignition nozzle 7 passes through the furnace chamber 4 and is settled in the chamber body of the furnace chamber 4 and below the porous combustion radiant panel 5, a sundries baffle 8 is provided in the furnace chamber 4 below the porous combustion radiant panel 5 and above the ignition nozzle 7, the ignition needle 6 is set above the porous combustion radiant panel 5 which is set above the ignition nozzle 7, the needle apex of the ignition needle 6 is placed 1 mm to 10 mm above the porous combustion radiant panel 5; the ignition needle 6 and the housing of the furnace chamber 4 can form an ignition circuit, wherein the housing of the furnace chamber 4 serves as an ignition negative pole, or alternatively an independent ignition negative pole 9 can be added; when the burner is a double ring burner, the ignition needle 6 and the sundries baffle 8 can be placed in the inner ring of the double ring burner, and they also can be placed in the outer ring of the double ring burner; the porous combustion radiant panel 5 can be porous ceramic radiant panel, metal mesh combustion radiant panel, metal fiber combustion radiant panel, metal honeycomb body combustion radiant panel, foam metal combustion radiant panel, wire mesh combustion radiant panel or metal hole combustion radiant panel; the ignition needle 6 meanwhile can be used as a flame ionization probe of a accidental flameout protection device. Therefore, when ignite the gas burner, open the ignition valve 1, and the ignition needle 6 generates an ignition spark above the porous combustion radiant panel 5 if the ignition nozzle 7 and the nozzle 2 both supply gas.
Because the ignition nozzle 7 is placed in the furnace chamber 4, the gas for ignition ejected from the ignition nozzle 7 quickly mixes with the air inside the furnace chamber 4, the gas-air mixture escapes from fire holes of the porous combustion radiant panel 5 above the ignition nozzle 7, and the gas concentration is relatively high and suitable for igniting, the main burner can be quickly ignited. Due to the suitable dispersity and concentration of the ignition flame, there is no obviously incomplete combustion, no black smoke, and it brings a high ignition rate. The situation that the ignition nozzle 7 is blocked caused by sundries, such as fluids, filtering through the porous combustion radiant panel 5 during normal use, can be avoided by placing the sundries baffle 8 above the ignition nozzle 7 and below the porous combustion radiant panel 5. When the ignition needle 6 is used both as a flame ionization probe of an accidental flameout protection device and as an ignition needle for ignition flame, the circuit of the pulse controller can be designed such that the ignition needle 6 emits ignition sparks at the beginning of the ignition, and after the burner is ignited, the ignition needle 6 immediately becomes a probe for detecting the combustion flame signal of the burner.
The present invention can be used for domestic gas appliances, gas warmer, gas barbecue oven, gas drying plant, and so on, and the structures of the porous combustion radiant panel 5 and the furnace chamber 4 can be rounded, square, rectangle or other shapes; for the structure of the double ring burner, it can be inner and outer ring structure, or be left and right separated ring structure. For the burner with elongate structure, it can have two or more sets of ignition structures, each consisting of a ignition nozzle 7, a sundries baffle 8 and a ignition needle 6, and the two or more sets of ignition structures, as a whole, serve as the ignition system of the whole burner, so that the burner can be quickly ignited, and the flame can quickly spread to the whole ignition surface.
The present invention has the advantages of good performance in ignition, high reliability, good combustion performance, simple and credible structure, easy for installation and wide adaptation for gas.
