Description

Kitchen range burner Technical Field The utility model relates to the field of stoves, in particular to a stove burner. Background In the prior art, in order to realize the function of energy accumulation and smoke reduction, structures such as a pot support or an energy accumulation ring are generally improved, and a liquid containing disc of the cooker is only used for collecting overflows generated during cooking. The current improvement of the energy collecting ring generally increases the number of layers of the energy collecting ring to reduce heat loss, but simply increasing the number of layers of the energy collecting ring not only leads to the increase of the cost of the energy collecting ring, but also has less influence on the heat efficiency due to the increase of the number of layers of the energy collecting ring to a certain degree. Disclosure of utility model The technical problem to be solved by the utility model is to overcome the defects in the prior art and provide a kitchen range burner. The utility model solves the technical problems by the following technical scheme: A stove burner comprises a liquid containing disc and an annular heat collecting cover, wherein the heat collecting cover is arranged above the liquid containing disc, a secondary air inlet space is formed between the heat collecting cover and the liquid containing disc in the vertical direction, two ends of the secondary air inlet space in the radial direction of the heat collecting cover are penetrated, the upper end face of the liquid containing disc is parallel to a horizontal plane, the outer peripheral face of the liquid containing disc is inclined towards the radial outer side of the heat collecting cover from top to bottom, the inner peripheral face of the heat collecting cover is inclined towards the radial inner side of the heat collecting cover from top to bottom, and a plane where the inner peripheral face of the heat collecting cover is located passes through the boundary line between the upper end face of the liquid containing disc and the outer peripheral face of the liquid containing disc. In this scheme, the inner peripheral face of heat collection cover and the up end of flourishing liquid dish constitute "bowl form" gathers can the space to improve and gather can the effect, improve thermal efficiency. Compared with the plane moving only through the upper end face of the liquid containing disc, the bottom of the bowl-shaped energy collecting space can be prevented from being exposed, the energy collecting effect is further ensured, a plurality of heat insulation layers are not needed to be arranged in the heat collecting cover, and the cost of the heat collecting cover is reduced. Compared with the plane moving outwards only passing through the outer peripheral surface of the liquid containing disc, the radial length of the secondary air inlet space can be increased, so that the secondary air inlet area is ensured, and the combustion efficiency is improved. Preferably, the outer peripheral surface of the liquid containing disc is a curved surface, and the outer peripheral surface of the liquid containing disc is curved towards the inside of the liquid containing disc. In the scheme, the outer peripheral surface of the curved liquid containing disc can better guide the flow of secondary air, reduce the resistance of the secondary air and enable the secondary air to flow into the combustion area stably and smoothly. Preferably, the heat collecting cover is of a hollow structure, and the peripheral wall of the heat collecting cover is parallel to the vertical direction. In this scheme, above-mentioned setting makes the medial surface of the outer peripheral wall of heat collection cover can reflect the heat infrared ray to the inner peripheral wall of heat collection cover, reduces the heat and runs off. Preferably, the lower end surface of the inner peripheral wall of the heat collecting cover is located above the lower end surface of the outer peripheral wall of the heat collecting cover. In this scheme, above-mentioned setting is in order to guarantee when heat infrared ray reflects between the inner peripheral wall and the periphery wall of heat-collecting cover on the one hand, and the heat infrared ray that the inner peripheral wall of heat-collecting cover was towards the periphery wall reflection of heat-collecting cover all falls on the periphery wall of heat-collecting cover, prevents that heat from directly flowing out the heat-collecting cover, improves thermal efficiency. On the other hand, the secondary air flowing towards the radial inner side of the heat collection cover can be prevented from being blocked by the lower edge of the inner peripheral wall of the heat collection cover, the mobility of the secondary air is ensured, the occurrence of the condition of air flow disorder is prevented, and the rise of smoke is prevented. Preferably, the included angle between the inner peripheral sur
