Problems solved by technology

The main body of the fire distributor is usually formed by forging. In order to meet the requirements of the forging process, the structural size of the main body of the fire distributor is difficult to further optimize, and it involves the optimization of the structural size of the entire burner.
In addition, the material of the main body of the burner that cooperates with the main body of the fire distributor is also limited by the temperature resistance of the material at the fire hole not lower than 700°C
It is precisely because of the limitation of the material at the fire hole that the production cost of this patent is high, and the opti

Embodiment 1

[0040] Such as figure 1 As shown, this embodiment is a top-inlet multi-layer inner flame burner, which includes a burner body 1 and a fire splitter device 2. The burner body and the fire splitter device are combined by a cylindrical surface and a plane; the burner body is The upper air inlet structure; the fire distributor device is composed of the fire distributor main body 201, the upper fire cover 202, and the lower fire cover 203. The inner cavity of the fire distributor main body communicates with the inner cavity of the burner body; the upper fire cover is installed on the upper end of the fire distributor body; the burner The main body has several screw holes 101 in the corresponding position of the lower fire cover, and is provided with an installation plane 102 corresponding to the lower fire cover; the lower fire cover is connected with the main body of the fire splitter and the burner body by screws.

[0041] Such as figure 2 As shown, the main body 201 of the fire di...

Embodiment 2

[0045] This embodiment is the same as Embodiment 1 except for the following features:

[0046] Such as Figure 7 As shown, this embodiment is a bottom-inlet multi-layer inner flame burner, which includes a burner body 1 and a fire splitter device 2, and the burner body 1 and the fire splitter device 2 are joined together by a cylindrical surface; the burner body For the lower air intake structure, there is no screw hole 101 on the burner body; the inner side wall section of the lower fire cover 203 ( Figure 8 In 203.8), there is no inwardly convex arc section 203.3, and there is no inner cavity 203.6 formed by the arc section; the lower fire cover passes through the inner side wall section 203.8, the outer cylindrical section 203.9 and the main body of the fire divider and the burner The main body is buckled into one body.

Embodiment 3

[0048] There is no figure in this embodiment, please refer to the related figure in embodiment 1. Except that the setting of the fire hole of the upper fire cover is different from that of the first embodiment, the rest is the same as that of the first embodiment. The difference is that there are dozens of strip-shaped fire holes 202.1 on the top of the upper fire cover (the number of fire holes can be determined according to actual needs); there are two circular fire holes on the cone surface of the upper fire cover (according to actual needs) Determine the number of fire holes), two circles of circular fire holes are staggered and evenly distributed along the circumference.

Abstract

The invention discloses a multi-layer inner flame combustor and a gas cooker with the same. The multi-layer inner flame combustor comprises a combustor main body 1 and a distributor device 2, wherein the combustor main body is combined with the distributor device together through a cylindrical surface, a circular conical surface or a flat surface; the combustor main body has an upper wind inlet structure; the distributor device consists of a distributor main body 201, an upper flame cover 202 and a lower flame cover 203; the distributor main body is not provided with a flame hole and is molded by pressure casting through an aluminum alloy material; the upper flame cover is arranged at the upper end of the distributor main body; a plurality of screw holes 101 and an installation surface 102 corresponding to the lower flame cover are formed at the position of the combustor main body corresponding to the lower flame cover; and the lower flame cover is integrally connected with the distributor main body and the combustor main body through screws. In the combustor and the gas cooker, a plurality of layers of inner flames are subjected to layered combustion and segmentation oxygen supplementation to form cubic flames which are spatially distributed in a staggered way, low CO and NO emission is realized, and obvious effects of energy saving and environmental friendliness are achieved.

Description

Technical field [0001] The invention relates to the field of gas stoves, in particular to a multi-layer inner flame burner and a gas stove equipped with the multi-layer inner flame burner. Background technique [0002] The development of gas stoves pays more and more attention to "energy saving and environmental protection"; inner flame gas stoves have received widespread attention due to their remarkable energy-saving effects. [0003] One of the contents of the invention disclosed in the Chinese invention patent "A burner for an inner flame gas stove" (Patent No.: 200710305041.1, Authorized Announcement No.: CN101403500B) is as follows: A burner for an inner flame gas stove, which consists of the burner body and The main body of the burner includes the burner head and the center fire cover. The main body of the burner includes the main body of the fire distributor and the top cover of the fire distributor. The main body of the burner and the fire distributor device are combined b...
