本专利的原理是: 通过出火孔的角度调置来降低到锅底距离, 这种调整虽然会增加热效 率, 但是必定会带来进二次空气时与空气有效接触不够的问题, 因此传统的燃烧器均不敢轻 易降低到锅底距离。 而本专利釆用通过多种结构的改进来解决空气有效接触不够的问题, 主 要是通过出火孔的交叉排列使得炉芯火焰和火盖内圈火焰交叉, 增加了空气接触面积使锅底 受热均衡。  The principle of this patent is: Reduce the distance to the bottom of the pot by adjusting the angle of the fire hole. Although this adjustment will increase the thermal efficiency, it will definitely bring about insufficient contact with the air when entering the secondary air, so the traditional combustion The device does not dare to easily reduce the distance to the bottom of the pot. However, this patent uses a variety of structural improvements to solve the problem of insufficient effective air contact, mainly through the cross-arrangement of the fire holes to cross the flame of the furnace core and the inner ring of the fire cover, and increase the air contact area to make the bottom of the pot heat-balanced. .

The furnace pan 5 is provided with an ignition pin positioning groove 5-3 communicating with the ignition hole 5-5, and a thermocouple positioning groove 5-4 communicating with the flameout protection hole 5-6.
炉盘的设计原理说明: 火盖 3安装在炉盘上, 通过炉盘定位柱 5-1的定位作用来限定火 盖 3沿轴线不能在炉盘上转动, 炉芯 1安装在炉盘中心, 是通过炉芯定位块 1-3和炉盘定位 槽 5-2实现定位控制轴向转动; 通过上述二个定位结构来保证每个炉芯出火孔 1-2的出火位 置正好朝向相应的一个火盖进气通道 4的通道口位置。 为了保证稳焰燃烧, 炉芯 1与炉盘中 心之间的间隙必须要均匀,才能通过稳焰槽 5-8和炉芯 1与炉盘中心之间的间隙向外漏煤气。 现有技术是通过三点定位来实现定位和间隙均匀, 但是三点定位安装时非常麻烦, 要试好多 次才能顺利安装好;本专利采用一个炉芯定位块 1-3和二个炉盘定位凸台 5-7 (凸出二个点), 与炉芯定位块 1-3构成三点定位, 安装方便; 同时通过二个炉盘定位凸台 5-7保证炉芯 1与 炉盘中心之间的间隙均匀。  The design principle of the hob is as follows: The fire cover 3 is mounted on the hob, and the positioning function of the hob positioning post 5-1 is used to define that the fire cover 3 cannot be rotated on the hob along the axis, and the furnace core 1 is installed in the center of the hob. The positioning control axial rotation is realized by the furnace core positioning block 1-3 and the furnace disk positioning groove 5-2; the above two positioning structures are used to ensure that the fire position of each furnace core fire hole 1-2 is exactly facing a corresponding fire. Cover the position of the passage opening of the intake passage 4. In order to ensure stable flame combustion, the gap between the core 1 and the center of the hob must be uniform to allow gas leakage through the gap between the flame holding groove 5-8 and the center of the furnace 1 and the center of the hob. The prior art realizes positioning and gap uniformity through three-point positioning, but the three-point positioning installation is very troublesome, and it is necessary to try several times to be successfully installed; this patent adopts a furnace core positioning block 1-3 and two hob positioning. The bosses 5-7 (two points protruding) form a three-point positioning with the furnace positioning block 1-3, which is convenient to install; at the same time, the two cores are positioned by the two positioning holes 5-7 to ensure the core 1 and the center of the hob The gap between the gaps is even.
