Problems solved by technology

However, the traditional completely upward air-intake burner is realized through the gap between the air-mixing chamber and the base when the primary air is supplemented. The problem caused by this is that there is a gap between the air-mixing chamber and the base. After the installation screws are installed, the installation screws can be seen from the outside of the burner, resulting in an unattractive appearance of the burner
Moreover, after a gap is set between the base and the air mixing chamber, the overflow will flow through the gap into the base and the circular basin-shaped main body located under the panel, that is, the term "bottom cup". There are many problems in user maintenance and cleaning. Inconvenient, and if the overflow is not cleaned for a long time, it will affect the normal use of the burner
In addition, the structure of the "bottom cup" makes the outlet of the ejector tube and the mixed gas channel connect with a sharp bend, which significantly increases the ejection resistance. Such a design is such as the Chinese patent No. ZL201120156854.0 (authorized announcement No. CN202082922U). The utility model patent "Gas Burner" has a poor ejection effect. At the same time, the primary air supplied by this type of upward air-intake burner from above the panel enters the "bottom cup" using the negative pressure generated by the nozzle jetting gas, which is easy The air flow distribution of the primary air is uneven, which affects the primary air coefficient to a certain extent, so that the pressure of the gas flowing out of the fire holes arranged along the circumferential direction of the outer ring fire cover or the inner ring fire cover is uneven, resulting in the formation of the outer ring fire cover. The flame of the inner ring fire produced by the outer ring fire or the inner ring fire cover is not uniform. At the same time, the second ejector tube and the first ejector tube of this type of burner are integrated with the "bottom cup" or integrated with the "bottom cup". The separate setting of the bottom cup, whether it is the problem of poor ejection effect caused by the integrated setting with the "bottom cup", or the safety hazard caused by the air leakage caused by the seam caused by the separate setting of the bottom cup , both need to make further improvements to the existing upward air-intake burners
In addition, there is a class of Chinese invention patent application publication "A Multi-Nozzle, Large Flow, and Completely Updraft Embedded Burner for Household Gas Stove" (publication number CN101446415A) such as the application number of which is 200810220263.8. The inner and outer nozzles corresponding to the ring ejector are respectively arranged on both sides within the diameter range of the burner, which can effectively improve the limitation of the short length of the ejector tube, and at the same time realize the independent adjustment of the inner and outer fires, and the combustion power is relatively large , the pursuit of high-power up-inlet burners has become the mainstream trend, but because the inner and outer ring ejectors are still set in the "bottom cup", the overall height of the burner is still high, and the overall aesthetics is poor

Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] Such as Figure 1-10 Shown is the preferred embodiment of this embodiment. The upper air intake burner of this embodiment includes a first injection pipe 2 and a base 11, wherein the first injection pipe 2 includes an air outlet end 23 and an air inlet end 24, and a second air inlet end 24 is fitted. An injector 5; and the base 11 is an inverted T shape with interconnected horizontal pipes 111 and vertical pipes 112, the horizontal pipe 111 surrounds the outside of the pipe wall of the first injection pipe 2, and the entrance of the horizontal pipe 111 That is the air inlet end 24, the end of the horizontal pipe 111 is a blind end, the air outlet end 23 is close to the blind end, and also includes a first air mixing chamber 1 that covers the vertical pipe 112 to form the centrally located first air mixing chamber 1. The fire cover 3, ...

Abstract

The invention relates to an upper air inlet combustor. The combustor is characterized by comprising a first injection pipe, an inverted T-shaped base, and a first fire cover; the first injection pipecomprises an air outlet end and an air inlet end, and a first ejector is matched at the air inlet end; and the first fire cover overlies a vertical pipe to form a centrally located first air mixing chamber. Compared with the prior art, the combustor has the advantages that the first injection pipe is completely enclosed in a horizontal pipe of the base, and the first injection pipe cannot be madeto be too long due to processing limitation, therefore, a spiral channel formed by spiral ribs on the inner wall of the horizontal pipe in the base can drive gas and primary air to enter the first airmixing chamber after being uniformly mixed along the spiral channel, so that the flame of the upper air inlet combustor is short, uniform and powerful, and the defects of yellow flame, tempering andthe like are avoided.

Description

technical field [0001] The invention relates to a burner for a gas cooker, in particular to an upward air-intake burner for a cooker with multiple nozzles. Background technique [0002] At present, many gas cookers have begun to use fully upward air-intake burners. Since the complete upward air-intake burners burn, the primary and secondary air required for combustion come from the upper part of the cooker panel, so the chassis of the gas cooker It can be fully sealed. Compared with the traditional bottom air intake structure burner, the completely upward air intake burner is not only safer to use, but also can well solve the problem of stove flameout caused by opening and closing the cabinet door. However, the traditional completely upward air-intake burner is realized through the gap between the air-mixing chamber and the base when the primary air is supplemented. The problem caused by this is that there is a gap between the air-mixing chamber and the base. After the moun...
