Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of gas cookers, in particular to a burner of a gas cooker and the gas cooker with the burner.
[ background of the invention ]
Before combustion, gas of the gas stove is premixed with air sucked by the injection pipe, and the mixed gas flows out through a fire outlet of the combustor and is ignited to form flame. The air generally drawn in by the ejector tube for mixing with the gas is referred to in the industry as primary air, while the air supplemented by the gas during combustion is referred to as secondary air, which is generally supplied by the air flow around the burner.
However, many times the air flow around the burner is insufficient for combustion. In particular, in recent years, a burner having a large heat load, which is preferred by consumers, cannot satisfy a combustion demand at all only by air flow around the burner, and is liable to cause insufficient combustion, low in heat efficiency, and also generate gas harmful to the human body and the environment due to insufficient combustion of gas.
[ summary of the invention ]
The present invention is directed to at least one of the above technical problems, and an improved burner of a gas cooker and a gas cooker having the same are provided.
In order to achieve the technical purpose, the invention provides the following technical scheme: a burner of a gas stove comprises a burner base and a fire cover, wherein the fire cover comprises an inner ring fire cover and an outer ring fire cover surrounding the periphery of the inner ring fire cover, and fire outlets for gas to flow out are formed in the inner ring fire cover and the outer ring fire cover; the burner also comprises a first air channel and a second air channel, wherein the first air channel supplies combustion supplementary air for the gas flowing out of the fire outlet hole of the outer ring fire cover, the second air channel supplies combustion supplementary air for the gas flowing out of the fire outlet hole of the inner ring fire cover, and the air supply of the first air channel and the air supply of the second air channel are mutually independent.
The inner ring fire cover of a general burner has the functions of igniting and maintaining small fire, and the heat load of the inner ring fire cover of the general burner is lower than that of the outer ring fire cover of the burner, for example, the heat load of the inner ring fire cover is 0.8kw, and the heat load of the outer ring fire cover is 3.2 kw. Therefore, the air quantity required by the inner fire cover of the combustor in unit time is different from that of the outer fire cover of the combustor in the combustion process of the combustor. And different air quantities are supplemented to the outer ring fire cover and the inner ring fire cover of the combustor only through the structural design of the first air channel and the second air channel, which has high requirements on structural design and manufacturing. Errors in the actual manufacturing process easily cause the air supply amount or proportion of the inner ring and the outer ring of the finally manufactured burner to deviate from the preset value, and further the secondary air supply of the inner ring fire cover or the outer ring fire cover of the burner is excessive or insufficient. The excessive supplement of the secondary air causes resource waste, and the insufficient supplement can cause insufficient combustion of the fuel gas.
It should be noted that the "gas" mentioned in the present invention is not limited to pure gas, and it should include a mixture of gas and air. For example, the gas mixture is premixed with air sucked from the ejector pipe.
The air supply of the first air channel and the air supply of the second air channel are mutually independent, so that the secondary air quantity supplied to the outer ring fire cover and the inner ring fire cover of the combustor can meet the requirement by regulating or controlling the air supply quantity of the first air channel and/or the second air channel. The burner of the present invention can reduce the structural and manufacturing requirements for the first air passage and the second air passage.
In this connection, "the air supplies of the first air passage and the second air passage are independent from each other" is to be understood that, when the air supply amount of one or more of the air passages is changed, the air supply amount of the remaining air passages may not be affected, and the change in the air supply amount of these air passages is not affected from each other. For example, the first air channel is connected with the first air generating device, and the second air channel is connected with the second air generating device; for another example, the first air passage is connected to an air generating device, and the second air passage is connected to an opening communicating with the atmosphere; for example, the first air passage and the second air passage are both connected to the same air generating device, but the air flow rates into the first air passage and the second air passage can be independently controlled; or the first air channel is connected with one opening communicated with the atmosphere, the second air channel is connected with the other opening communicated with the atmosphere, and the sizes of the two openings can be respectively and independently adjusted. The above is given by way of a limited example and does not exclude other possibilities.
It should be understood that the "outer ring fire cover" and the "inner ring fire cover" referred to in the present invention may be separate members or may be a single member, for example, in one embodiment, the burner includes a single fire cover, and the outer ring fire cover and the inner ring fire cover refer to the peripheral region of the fire cover and the central region of the fire cover, respectively.
Besides the above technical solutions, the present invention also provides one such technical solution: a burner of a gas stove comprises a burner base and a fire cover, wherein the fire cover comprises an inner ring fire cover and an outer ring fire cover surrounding the periphery of the inner ring fire cover, and fire outlets for gas to flow out are formed in the inner ring fire cover and the outer ring fire cover; the combustor also comprises a first air channel and a second air channel, wherein the first air channel supplies supplementary air for combustion of the fuel gas flowing out of the fire outlet holes of the outer ring fire cover, the second air channel supplies supplementary air for combustion of the fuel gas flowing out of the fire outlet holes of the inner ring fire cover, and the air flow of the first air channel and/or the second air channel is suitable for being independently controlled.
Therefore, the secondary air quantity supplied to the inner ring fire cover and/or the outer ring fire cover can be adjusted according to the actual heat load of the inner ring fire cover and/or the outer ring fire cover of the combustor, and the secondary air supplement quantity can be accurately controlled. In the actual use process, when the air supply amount or the ratio of the first air passage and/or the second air passage does not accord with the preset value, the adjustment can be independently carried out.
Wherein "the air flow rates of the first air passage and/or the second air passage are adapted to be controlled independently" shall include, but not be limited to, the following cases: the first air channel is connected with the first air generating device, the second air channel is connected with the second air generating device, and the first air generating device and the second air generating device can be respectively and independently controlled; or the first air channel is connected with an air generating device, the second air channel is connected with an opening communicated with the atmosphere, and the size of the opening can be adjusted; for example, the first air passage and the second air passage are both connected to the same air generating device, but the air flow rates into the first air passage and the second air passage can be independently controlled; or the first air channel is connected with one opening communicated with the atmosphere, the second air channel is connected with the other opening communicated with the atmosphere, and the sizes of the two openings can be respectively and independently adjusted.
