Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

In the related art, a cassette furnace adopts a U-shaped combustion tube, the upper part of the U-shaped combustion tube is provided with a plurality of fire holes, one end of the U-shaped combustion tube is an open end of a nozzle for connecting a gas pipe, and the other end of the U-shaped combustion tube is a closed end. When the gas is jetted into the U-shaped combustion pipe from the nozzle at a high speed, air can be simultaneously jetted to enter, and at the moment, the ignition system of the cassette furnace can ignite the gas after mixing the air through the ignition needle to finish ignition. Compared with the combustion pipes with other structural forms, the U-shaped combustion pipe has the advantages of large heating area and high heat load, thereby being particularly suitable for large-size cookers and meeting the outdoor dining requirements of multiple persons.

The plurality of fire holes of the U-shaped combustion pipe are generally arranged in two rows in the front and the back of the two straight pipe parts, and the fire holes are not arranged in the bent pipe part. The gas flow in the U-shaped combustion pipe can be subjected to resistance from the pipe wall, so that the gas is unevenly distributed in the U-shaped combustion pipe, and the gas flow close to the nozzle has higher speed, while the gas flow close to the closed end has obviously reduced speed, which easily causes flame separation and even fire extinguishing of a plurality of fire holes close to the nozzle in the front fire discharge holes. Flame-off is understood to mean that in normal operation of the burner, the speed of the gas jet leaving the flame holes should be adapted to the burning speed, so that the flame is in a steady state, but when the gas flow rate is too high, so that the gas jet leaving the flame holes is faster than the burning speed, the flame will be in a fluttering state, which is called flame-off, and when the flame is completely extinguished, the time for transferring the flame (i.e. transferring the flame) is longer. Due to the reasons, certain potential safety hazards exist when the card type stove is used, and the cooking experience and the cooking effect are greatly reduced.

In the related art, some gas furnaces using other structure type combustion tubes have similar technical problems to those of the related art.

In order to solve the technical problem, an embodiment of the present disclosure provides a burner system and a gas furnace including the burner system, so as to improve the phenomena of flame separation and fire release when the gas furnace is in operation, and improve the success rate of ignition.

The combustion tube of the burner system includes, but is not limited to, a U-shaped combustion tube. For example, in some embodiments, the combustion tube may also be a straight tube type combustion tube. The number of burner tubes included in the burner system is not limited, and may be one, two, or more. For example, in some embodiments, the burner system includes one straight tube type combustion tube; in other embodiments, the burner system includes a U-shaped burner tube; in still other embodiments, the burner system may further include at least two straight tube type combustion tubes arranged in parallel with open ends on the same side; etc., and further embodiments are not listed here.

The side of the burner or parts thereof closer to the operator is defined as "front" and the side further away from the operator as "rear" with reference to the usual state of placement of the burner when in use. For example, the front row of fire holes of the U-shaped burner refers to one of the two rows of fire holes closer to the operator, and the rear row of fire holes refers to one of the two rows of fire holes farther from the operator. The side of the gas burner or part thereof closer to the cooker, i.e. further from the gas burner platform, is defined as "up", and correspondingly the side of the gas burner or part thereof further from the cooker, i.e. further from the gas burner platform, is defined as "down".

The furnace body 2 serves as a main frame of the gas furnace 1 for accommodating, supporting and mounting other components, and when the gas furnace 1 is in use, a cooker such as a pot is placed on the pot rack 209 of the furnace body 2. In order to improve the structural strength, the heat dissipation effect and the use safety of the gas furnace, the furnace body 2 generally adopts a sheet metal furnace body. The burner system 3 is used to provide a combustion flame to the cookware to heat the contents of the cookware. The gas supply system 4 is used to continuously supply gas to the burner system 3 via gas lines 401. The ignition system 5 is used to ignite the burner system 3 through an ignition needle 501 (shown in fig. 6) in the case where the gas supply system 4 continues to supply gas.

In addition, the gas furnace 1 may further comprise a fire power adjusting system 6, and the fire power adjusting system 6 comprises, for example, an adjusting knob 601, a valve body 602, a valve body bracket 603 and the like as shown in fig. 2, and is used for adjusting the supply flow rate of the gas, so as to adjust the size of the combustion flame to meet different cooking requirements.

The flame stabilizing screen 304 further interferes with, or slows down, the flow of gas as it is ejected away from the fire holes 302 covered by the flame stabilizing screen 304. Under the action of the flow distribution plate 3051 and the flame stabilizing wire mesh 304, the speed of the gas spraying out of the fire holes 302 covered by the flame stabilizing wire mesh 304 is obviously reduced and can basically adapt to the combustion speed, so that the phenomena of flame leaving and flame dropping can be effectively improved, the flame can be quickly transmitted to other fire holes 302, and the ignition success rate of the gas furnace is improved.

In this way, the installation of the flame stabilizing wire mesh 304 is simple, and the combustion pipe 301 itself does not need to design an installation structure for the flame stabilizing wire mesh 304, such as screw holes for installing the flame stabilizing wire mesh, so that the processing cost of the combustion pipe 301 is low. In some other embodiments of the present disclosure, the flame stabilizing mesh may also be fixed directly to the surface of the combustion tube, for example by welding, or by screws.

In some embodiments, the diverter plate 3051 and the mounting plate 3052b are integrally connected at the fire transfer holes 307, i.e., the fire transfer holes 307 act as the aforementioned perforations. It will be appreciated that in the disclosed embodiment, the mesh diameter of the flame stabilizing mesh 304 should be significantly smaller than the aperture of the fire holes 302 and the fire transfer holes 307, and the mesh size of the flame stabilizing mesh 304 should also be significantly smaller than the size of the fire holes 302 and the fire transfer holes 307, so that the gas can be ejected at a proper speed while being disturbed and slowed down by the flame stabilizing mesh 304.
