 Infrared gas burner with windproof function

Technical field

This invention relates to infrared gas burners, and more particularly to improvements in the combustion performance of domestic and domestic gas fired appliances.

Background technique

With the improvement of people's lives, the use of household-type cooking gas cookers, gas grills for households and out-of-home use, and indoor and outdoor heaters have been widely used, and the combustion performance of these products has also been greatly improved. However, the gas-fired performance of gas grills, heaters and gas cookers on the market is still relatively poor. These products basically use ion detection type or thermocouple in order to meet the requirements of windproof performance and basic requirements. An unexpected flameout protection device is implemented, or the windshield is enhanced by adding a windshield. These products and devices mainly have the following defects:
(1) By installing the accidental flameout protection device, only when the gas burning appliance product is unexpectedly extinguished, including a large wind blowing out the burner, the soup water will be extinguished by the burner, etc., the gas of the burner is passed through the electromagnetic valve. The air supply is turned off for safe use. This is not really a good way to improve the wind resistance of gas burning appliances. Gas burning appliances can not be used normally in a large wind environment, such as barbecue in the seaside environment, and can not meet the user's requirements.
(2) Whether using an ion detection type accidental flameout protection device or a thermocouple type accidental flameout protection device, the manufacturing cost of the product is greatly increased.
(3) The method of adding windshield around the gas burner to block the external wind and enhance the certain wind resistance, but its ability to block the external wind is poor, it is difficult to block the larger wind, and the external wind direction is slightly changed. At the moment, the wind resistance effect is not achieved immediately.

Therefore, it is a great technology in the technical field to truly improve the wind resistance performance of the gas burner in an outdoor use environment, to make the gas burner use normally and reliably under the environment of a large foreign wind, and the cost of the product is low. problem.

Summary of the invention

The object of the present invention is to improve the gas-burning capacity of the gas burner by improving the structure of the gas burner, increasing the air inlet and the air outlet, blocking the external wind, guiding the wind direction of the external wind, and using the combustion system to achieve a balance. The product adapts to various harsh environments, and the cost of the gas burner is not substantially increased, and the combustion performance of the combustion can be effectively improved.

The invention is realized by the invention: an infrared gas burner with a windproof function, comprising a nozzle (1), an ejector (2), a gas-air mixing chamber (3), an infrared combustion radiant panel (4), a burner The mounting plate (5) is composed of an outer chamber casing (6) installed on the outer side of the combustion system composed of the nozzle (1), the ejector (2), and the gas-air mixing chamber (3), and the gas in the burner A splitter plate (7) is installed in the air mixing chamber (3), and a wind shield (8) is mounted on the burner outer chamber mounting plate (5), and the wind shield (8) is installed at the front end of the infrared radiation plate (4). In the outer side of the burner infrared combustion radiation plate (4), there is an air inlet hole (9), and on the outer chamber casing (6), there is a discharge hole (10), an area of the air inlet hole (9) and a discharge hole ( The ratio of the area of 10) and the area of the infrared combustion radiant panel (4) is 1: (2.5~5): (14~20); when there is external wind blowing to the burner, the windshield (8) can block The wind in the combustor casing backstop prevents it from being blown directly to the infrared combustion radiant panel (4), and there will be some wind Entering from the air inlet hole (9), a certain pressure is formed in the outer chamber casing (6), and when the pressure is increased, some gas enters the burner gas-air mixing chamber (3) from the ejector (2), It can be overflowed from the infrared combustion radiant panel (4) together with the gas-air mixture by the splitting of the splitter plate (7), and is opposed to the external wind to form a certain pressure balance, and under the action of the windshield (8), A stable combustion is formed on the surface of the infrared combustion radiant panel (4) to achieve a good windproof effect; when the external wind force is too large, the wind pressure of the outer chamber casing (6) is relatively large, passing through the outer casing (6) By adding the unloading hole (10), it is possible to overflow the excessive air entering the outer chamber casing (6), reduce the wind pressure, and stabilize the outer chamber casing (6) wind pressure and stabilize the infrared combustion radiation plate ( 4) The effect of the burning of the surface. In the present invention, the infrared combustion radiation plate (4) may be a porous ceramic radiation plate, which may be a metal mesh type combustion radiation plate, may be a metal fiber type combustion radiation plate, may be a metal honeycomb type combustion radiation plate, may be a foam metal type The combustion radiant panel may be a wire mesh type combustion radiant panel or a metal hole burning radiant panel; the surface shape of the infrared radiant radiant panel (4) may be a circular shape, may be a square shape, may be a rectangular shape, and may be a trapezoidal shape. It can also be a combination of these shapes. Thus, the outdoor gas burner will guide the wind that is blocked by the combustion appliance product through the windshield (8), so that the blocked wind does not directly blow to the surface of the infrared combustion radiation plate (4). Through the pressure balance between the upper surface of the burner panel and the inner cavity of the burner, the combustion surface of the burner is not burned inward, and is not quenched, achieving good wind resistance. The invention can be used for gas grills and gas heaters for outdoor use, and has obvious use effect and superior use performance, and has strong wind resistance.

The gas burner adopting the structure and the method has good windproof performance, is safe and reliable, and has a simple structure, and is well solved for the defects that the gas burner is easily blown out by the wind when used outdoors, the combustion is insufficient, and the cost is high. To achieve safety, cost savings and improved combustion performance, it can meet the requirements of different products, different use environments and conditions. The invention is also applicable to gas cooker products.

The invention has the advantages that the infrared gas burner has strong wind resistance, good windproof performance, simple structure, low manufacturing cost, reliable performance and wide application range.

The ratio of the area of the radiant panel (4) is 1:3.5:16.5; when there is an external wind blowing toward the burner, the windshield (8) can block the wind of the burner housing back to avoid direct blowing to the infrared ray. Burning the radiant panel (4), part of the wind enters from the air inlet hole (9), in the outer chamber housing 6) A certain pressure is formed in the inside. When the pressure is increased, some gas enters the burner gas-air mixing chamber (3) from the ejector (2), and can be mixed with the gas air through the split of the splitter plate (7). The body overflows from the infrared burning radiant panel (4), and is opposed to the external wind to form a certain pressure balance, and under the action of the windshield (8), a stable combustion is formed on the surface of the infrared burning radiant panel (4). A good windproof effect is achieved; when the external wind force is too large, the outer casing (6) will have a relatively large wind pressure, and by adding a relief hole (10) to the outer casing (6), the outer casing can be entered. The body (6) overflows excessively, reduces the wind pressure, and functions to stabilize the outer chamber casing (6) wind pressure and stabilize the combustion of the surface of the infrared combustion radiation plate (4). In the present invention, the infrared combustion radiation plate (4) is a porous ceramic radiation plate, the surface of the infrared combustion radiation plate (4) has a rectangular shape, and the wind shield (8) is attached to the front end of the infrared combustion radiation plate (4). Thus, the outdoor gas burner will guide the wind that is blocked by the combustion appliance product through the windshield (8), so that the blocked wind does not directly blow to the surface of the infrared combustion radiation plate (4). Through the pressure balance between the upper surface of the burner panel and the inner cavity of the burner, the combustion surface of the burner is not burned inward, and is not quenched, achieving good wind resistance. The invention can be used for gas grills and gas heaters for outdoor use, and has obvious use effect and superior use performance, and has strong wind resistance. This gas burner has good wind resistance. The utility model has the advantages that the gas burner has strong wind resistance, good windproof performance, simple structure, low manufacturing cost and wide application range of reliable performance.
