Abstract

The utility model relates to a burner, comprising an upper burning ring, a lower burning ring and a venturi pipe. The upper section of the lower burning ring forms a horn shape, and the lower section of the lower burning ring forms a cylinder shape. The lower section of the upper burning ring forms a cylinder shape, and the upper section of the upper burning ring form an umbrella shape. The umbrella surface of the umbrella-shaped section is provided with fire holes. The upper burning ring is fixed in the lower burning ring. An air passage formed by the upper burning ring and the lower burning ring is communicated with the venturi pipe. The communicating part of the air passage and the venturi pipe is provided with a section of shrinking opening. The utility model solves the problem that the prior art has low heat efficiency and complicated structure. The utility model is used for gas-burning rice pots.

Description

Burner

The utility model belongs to a kind of stove or kitchen range of gaseous fuel, specially refers to the burner of Gas-burning rice pot configuration.

China's utility model patent 94218741 provides a kind of burner, its must by three of upper, middle and lower combustion ring forms and thermic load lower, the thermal efficiency is low, and 94218082 provide a kind of burner of high heat load, but complex structure, the cost increase.

The purpose of this utility model is, designs a kind of thermal efficiency height, burner simple in structure.

The utility model comprises combustion ring, lower combustion ring and Venturi tube, and the epimere of lower combustion ring is horn shape, and the hypomere of lower combustion ring is barrel shape; The epimere of upper combustion ring is the umbrella shape shape, on the umbrella cover of umbrella shape shape fire hole is arranged, and the hypomere of upper combustion ring is barrel shape; Upper combustion ring is fixed in the lower combustion ring, so that form air flue between upper combustion ring and the lower combustion ring, above-mentioned air flue and Venturi tube are connected, and above-mentioned air flue and Venturi tube connection place have one section reducing.

On the umbrella cover of upper combustion ring of the present utility model fire hole is arranged, fire hole strengthens with the contact-making surface of pot, increased the thermal efficiency, and the utility model only has three parts, all can make cost 10% of a punching press of thin plate, again owing on the air flue between the upper and lower combustion ring reducing is arranged, air-flow is further accelerated before burning, and combustion conditions is good, tempering-free phenomenon.

The vertical view of Fig. 2: Fig. 1

Fig. 3: the A-A view among Fig. 2

As shown in Figure 1: a kind of embodiment is made up of heat insulation loop 1, upper combustion ring 2, lower combustion ring 3 and Venturi tube 5.Venturi tube 5 is made up of upper shell 7 and lower house 8, and upper shell 7 and lower house 8 are riveted together.

As shown in Figure 2: upper shell 7 and lower house 8 are all the snail shape, the epimere of last combustion ring 2 is the umbrella shape shape, fire hole is arranged on the umbrella cover, fire hole can be done circular or square, present embodiment adopts clearance type fire hole 6, mainly is because it makes contact-making surface simple, can increase fire hole and pot under the situation that does not increase the present embodiment size.

As shown in Figure 3: the epimere of lower combustion ring 3 is horn shape, and the hypomere of lower combustion ring 3 is barrel shape; The epimere of upper combustion ring 2 is the umbrella shape shape, and the hypomere of upper combustion ring 2 is barrel shape; The hypomere of upper combustion ring 2 and lower house 8 are riveted together, and the hypomere of lower combustion ring 3 and upper shell 7 are riveted together, and form air flue 9 between upper combustion ring 2 and the lower combustion ring 3, and above-mentioned air flue 9 has one section reducing 4 with Venturi tube 5 connections place.Present embodiment is with recessed one section of the hypomere of lower combustion ring 3, makes air flue 9 form reducing 4 at this; If the hypomere of upper combustion ring 2 is outwards protruded one section, also can make air flue 9 form reducing 4 at this, perhaps, simultaneously the recessed one section hypomere with upper combustion ring 2 of the hypomere of lower combustion ring 3 is protruded one section, make air flue 9 form reducing 4 at this.Heat insulation loop 1 is welded on the combustion ring 2.

Claims
