Description

Technical Field

[0001] The utility model relates to a burner with an air outlet nozzle, belonging to the field of kitchen appliances. Background Art

[0002] The burner is a commonly used kitchen utensil in the household for cooking food, and comprises an inner ring fire cover 1, an outer ring fire cover 2, an air distribution plate 3, a base 4, an ignition needle 5 and a thermocouple 6. The burner in the prior art usually directly opens an ignition air outlet and an induction air outlet nozzle hole on the air distribution plate 3, but does not provide an ignition air outlet nozzle 7 and an induction air outlet nozzle 8, which will cause the mixed gas to flow out too fast, and the flame on the inner ring fire cover will show a flame separation phenomenon; and there is no ignition anti-blocking boss 11 and induction anti-blocking boss 14 on the inner ring fire cover 1, which makes it possible for the hydraulic overflow in the pot body during cooking to cause the ignition air outlet and the induction air outlet nozzle hole to be blocked.

[0003] In addition, the first ring-slit fire groove 23 and the second ring-slit fire groove 24 provided on the outer ring fire cover 2 are provided in correspondence, that is, the first ring-slit fire groove 23 and the second ring-slit fire groove 24 can only replenish secondary air from one side. Therefore, the two first ring-slit fire grooves 23 and the second ring-slit fire grooves 24 provided in correspondence with each other will affect the replenishment of secondary air, and thus affect the combustion efficiency; at the same time, the first ring-slit fire hole 21 and the second ring-slit fire hole 22 are provided vertically and perpendicular to the bottom of the pot body, resulting in a small negative pressure and a small flow rate during combustion, making it difficult to replenish secondary air.

[0004] In view of this, a burner with an annular flame is disclosed in the patent document with application number 201510245108.1. The fire holes 21 in the above-mentioned prior art are arranged corresponding to each other inside and outside, which affects the replenishment of secondary air. In addition, the fire holes 21 are arranged vertically and perpendicular to the bottom of the pot body. It is difficult to replenish secondary air during combustion, resulting in low combustion efficiency. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a burner with a gas outlet nozzle and a reasonable structural design.

[0006] The technical solution adopted by the present invention to solve the above-mentioned problems is: the burner with an air outlet nozzle includes an inner ring fire cover, an outer ring fire cover, an air distribution plate, a base, an ignition needle and a thermocouple, and the air distribution plate, the ignition needle and the thermocouple are all arranged on the base, and the inner ring fire cover and the outer ring fire cover are both arranged on the air distribution plate. Its structural feature is that it also includes an ignition air outlet nozzle and an induction air outlet nozzle, and the ignition air outlet nozzle and the induction air outlet nozzle are both arranged on the air distribution plate, and the ignition air outlet nozzle and the induction air outlet nozzle are respectively coordinated with the ignition needle and the thermocouple.

[0007] Furthermore, the ignition air outlet nozzle is provided with an ignition air outlet hole, a first ignition deceleration hole and a second ignition deceleration hole.

The ignition anti-blocking boss is provided with a first ignition fire transfer hole, and the induction anti-blocking boss is provided with a second induction fire transfer hole.

[0010] Furthermore, the ignition anti-blocking boss is located below the second ignition fire transmission hole, and the induction anti-blocking boss is located below the first induction fire transmission hole.

[0011] Furthermore, the ignition anti-blocking boss is located above the ignition air outlet nozzle, and the induction anti-blocking boss is located above the induction air outlet nozzle.

[0012] Furthermore, the first ignition flame transmission hole is arranged in parallel with the second ignition flame transmission hole, and the second induction flame transmission hole is arranged in parallel with the first induction flame transmission hole.

[0013] Furthermore, the outer ring fire cover is provided with a first ring strip fire groove and a second ring strip fire groove of an annular structure, the bottom of the first ring strip fire groove is provided with a plurality of first ring strip fire holes, and the bottom of the second ring strip fire groove is provided with a plurality of second ring strip fire holes.

[0014] Furthermore, the plurality of first annular slot fire holes and the plurality of second annular slot fire holes are arranged in a circular array, and the first annular slot fire holes and the second annular slot fire holes are staggered.

[0016] Compared with the existing technology, the utility model has the following advantages: the burner with an air outlet nozzle is achieved by installing an ignition air outlet nozzle and an induction air outlet nozzle on the gas distribution plate, and the apertures of the ignition air outlet hole, the first ignition deceleration hole and the second ignition deceleration hole arranged on the ignition air outlet nozzle are increased in sequence, and the apertures of the induction air outlet hole, the first induction deceleration hole and the second induction deceleration hole arranged on the induction air outlet nozzle are increased in sequence, so that the mixed gas can be decelerated when flowing out, and the flame separation phenomenon on the inner ring fire cover can be avoided, thereby playing a flame stabilizing role; at the same time, by arranging an ignition anti-blocking boss and an induction anti-blocking boss on the inner ring fire cover above the ignition air outlet nozzle and the induction air outlet nozzle, it can be avoided that the ignition air outlet nozzle and the induction air outlet nozzle are blocked due to liquid overflow in the pot during cooking.

[0017] A plurality of first ring-strip fire grooves and second ring-strip fire grooves arranged in a circular array are provided on the outer ring fire cover. Since the first ring-strip fire grooves and the second ring-strip fire grooves are staggered with each other, the supplement of secondary air by the first ring-strip fire grooves and the second ring-strip fire grooves will not be affected. That is, the secondary air can be supplemented to the first ring-strip fire grooves and the second ring-strip fire grooves at the same time on both the inner and outer sides of the outer ring fire cover, and the first ring-strip fire holes and the second ring-strip fire holes are inclined, which can increase the negative pressure and flow rate during combustion, which is beneficial to the supplement of secondary air, so that the combustion efficiency can be improved.
