Description

Burner and gas stove using same

Technical Field

The utility model relates to a combustor and use gas-cooker of this combustor.

Background

At present, the outer ring fire air outlet holes of the burners on the market are generally arranged on the periphery of the outer fire cover, when the gas stove is used, outer ring flames generated by the outer fire seat easily escape outwards along the bottom of the pot, and the heating efficiency is reduced. Moreover, the structural design causes a heat vacancy zone between outer ring flame generated by the outer fire seat and inner ring flame generated by the inner fire seat, which is not beneficial to uniformly heating the pot bottom. For the current user families with few people, small-quantity and various dishes are more popular, and further, higher requirements are put forward on the burner capable of concentrating heat for cooking.

For example, the utility model discloses a chinese utility model patent of the gas stove combustor of grant bulletin No. CN207162529U, the problem is a band shape goes out fire hole, discloses a band shape goes out fire hole's gas stove combustor, including the headstock, the headstock includes outer gas seat and internal-combustion engine seat, and outer gas seat is connected through a plurality of gas passages with the internal-combustion engine seat, is equipped with outer fire lid on the outer gas seat, is equipped with interior fire lid on the internal-combustion engine seat, and outer fire lid inner wall is equipped with the inclined plane of tilt up, and the inclined plane includes a plurality of sections inclined planes, is equipped with a plurality of annular on the inclined plane and goes out fire hole. The technical scheme of the utility model patent has following not enough: as can be seen from the attached drawings, the upward inclined mode is outward extension, and the structural design still can not avoid the outer ring flame from escaping along the bottom of the pot, so that the heating efficiency is low.

For another example, the chinese utility model patent of grant publication No. CN201866772U, entitled gas range burner fire lid and gas-cooker discloses a gas range burner fire lid, including outer ring fire lid, be equipped with the outer ring fire hole that leans out on the outer ring fire lid circumference lateral wall, the slope of outer ring fire lid circumference inside wall sets up, equipartition a week inner ring fire hole on outer ring fire lid circumference inside wall and the top surface, inner ring fire hole is the elongated slot shape or the circular of slope, and the flame play fire direction of inner ring fire hole is the ascending vortex form of slope. The utility model discloses a technical scheme that provides has following not enough: the fire outlet direction of the inner ring fire hole on the circumferential inner side wall of the outer ring fire cover is inclined upwards, a heat vacancy zone between the outer ring flame and the inner ring flame still exists, the outer ring flame easily escapes along the pot bottom, and the heating efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

For overcoming the defects of the prior art, the utility model provides a burner and gas stove using the burner, which have no heat vacancy zone between the outer ring flame and the inner ring flame, have the centralized firepower, prevent the heat from leaking and have high heating efficiency.

The utility model discloses mainly adopt following technical scheme:

the utility model provides a combustor, includes furnace end, fire seat, fire lid, ignition needle and flame-out protector, the fire seat sets up on the furnace end, the fire seat includes outer fire seat, fire lid is including outer fire lid, outer fire lid sets up on the outer fire seat, outer fire is covered and is provided with the venthole, the venthole sets up the inside wall of outer fire lid.

Wherein, the inside wall of outer fire lid has the transition face of inside slope from bottom to top.

Wherein the air outlet is arranged on the transition surface.

Wherein the cross-sectional profile of the transition surface is at least one of a straight line, a broken line or an arc line.

A gas stove comprises a panel and a pot support, and the gas stove uses the burner.

According to the utility model provides a technical scheme has following beneficial effect: the air outlet is arranged on the inner side wall of the outer fire cover, so that the distance between outer ring flame and inner ring flame is shortened, the firepower of the burner is more concentrated, and no heat vacancy zone exists between the outer ring flame and the inner ring flame; the inner side wall of the outer fire cover is formed into an inward concave type by the transition surface with the inner side wall inclined inwards from bottom to top, so that heat collection is facilitated, and the influence of cross wind on firepower can be effectively blocked; the air outlet is arranged on the transition surface which is inclined inwards, the distance between the air outlet and the pot bottom is increased, high-temperature outer flame of outer ring flame can be better utilized, and the heating efficiency is higher; the cross-sectional profile of the transition surface is preferably arc-shaped, which is more favorable for heat collection.

32 fire seats, 331 inner fire cover, 332 outer fire cover, 3320 air outlet hole, 3321 inner side wall, 33211 transition surface, 34 ignition needle and 35 flameout protector.

Detailed Description

The invention will be further elucidated with reference to the accompanying drawings:

referring to fig. 1, a combustor, includes furnace end, fire seat 32, fire lid, ignition needle 34 and flame out protector 35, and fire seat 32 sets up on the furnace end, and fire seat 32 includes outer fire seat, and the fire lid includes outer fire lid 332, and outer fire lid 332 sets up on outer fire seat, be provided with venthole 3320 on the outer fire lid 332, venthole 3320 sets up the inside wall 3321 of outer fire lid 332. Preferably, the fire cover further comprises an inner fire cover 331, the fire base further comprises an inner fire base, the inner fire cover 331 is arranged on the inner fire base, the structural design enables no heat vacant area to exist between inner ring flames generated by the inner fire base and outer ring flames generated by the outer fire base, the pot bottom is heated uniformly, firepower is strong, and the novel fire cover is suitable for modern families with fewer people and more dishes. Preferably, the gas outlet holes 3320 are circumferentially and uniformly distributed along the inner side wall 3321 of the outer fire cover 332, and the structural design ensures that the firepower of the outer fire cover of the burner is uniform.

Referring to fig. 1 and 2, the inner sidewall 3321 of the outer fire lid 332 has a transition surface 33211 inclined inward from bottom to top. The transition surface 33211 of the inner side wall 3321 inclines inwards from bottom to top, so that the inner diameter of a circle where the upper end of the inner side wall 3321 of the outer fire cover 332 is located is small, and the inner diameter of a circle where the lower end of the inner side wall 3321 of the outer fire cover 332 is located is large.

Referring to fig. 1 and 2, the outlet port 3320 is disposed on the transition surface 33211. The air outlet holes 3320 are arranged on the transition surface 33211 which is inclined inwards from bottom to top, the distance between the air outlet holes 3320 and the bottom of the pot is increased, high-temperature outer flame of outer ring flame can be better utilized, the firepower is strong, the heating efficiency is higher, and harmful gases such as carbon monoxide are prevented from being generated.

Referring to FIG. 2, the cross-sectional profile of the transition surface 33211 is at least one of a straight line, a broken line, or an arc line. Preferably, the cross-sectional profile of the transition surface 33211 is curved, which is advantageous for collecting heat.

Further, the firepower of the outer fire seat is smaller than that of the inner fire seat.

Although specific embodiments of the present invention have been described above, those skilled in the art may readily devise many variations of the present invention based on the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
