Embodiment 1

[0043] Such as figure 1 and figure 2 As shown, the present invention provides a cooker ejector, which includes a nozzle 1 and an ejector pipe 2 sequentially arranged along the airflow direction A. Wherein, the injection pipe 2 can be divided into three parts according to the change of the cross section along the gas flow direction, the constriction section 21, the horizontal section 22 and the expansion section 23, while the nozzle 1 includes a plurality of first outlets 11, and these first outlets 11 are Set toward the inlet direction of the constricted section 21, and these first outlets 11 are sequentially arranged circumferentially along the lumen edge 21a of the constricted section 21, so as to surround the lumen of the constricted section 21 (see for details figure 2 ). Through this structural arrangement, the gas ejected from the nozzle 1 from the first outlet 11 can directly act on the inner wall of the constricted section 21, which improves the air flow velocity o...

Embodiment 2

[0053] This embodiment provides a cooker ejector, the structure of which is substantially the same as that provided in Embodiment 1. The difference is that, in this embodiment, the injection tube 2 only includes the constricted section 21 and the horizontal section 22 , but does not include the expanded section 23 . Such as Figure 4 As shown, the end of the horizontal section 22 along the airflow direction A is closed, and a number of openings are provided on the side wall of the horizontal section 22, so that the mixed gas in the injection pipe 2 can communicate with the external stove fire cover. Wherein, these openings are arranged on the side wall surface of the horizontal section 22 around along the inner cavity section of the horizontal section 22 .

[0054] Since the horizontal section 22 in the present embodiment is also a polygonal structure, there is a corresponding relationship between the apertures of these holes and the straight-line distance between the holes a...

Abstract

The invention discloses an ejector tube and a cooker ejector including the ejector tube, wherein the ejector tube has a constricted section, and the inner cavity section shape of the constricted section is polygonal. Compared with the traditional circular, elliptical or other arc-shaped ejector tubes, the polygon can have more inner wall circumference when occupying the same cross-sectional area. Therefore, in the case of the same pipe cross-section, the The structure can effectively increase the area of ​​the inner wall of the ejector tube, so that more air can be sucked in under the same pressure on the surface of the inner wall, and the ejection effect of the ejector tube on air can be improved.

Description

technical field [0001] The invention relates to the field of burners, in particular to an ejector pipe and a cooker ejector containing the same. Background technique [0002] The injection pipe is one of the important components of the cooker, and receives the gas from the nozzle to use the gas flow to inject the air in the surrounding environment. The cross-sectional shape of the injection pipe is usually circular or elliptical, and it can be divided into a constricted section, a horizontal section and an expanded section according to the change of the cross-section along the gas flow direction. [0003] Wherein, the existing ejection tube has poor ejection ability to air, which directly affects the combustion effect of the cooker. Therefore, how to improve the ejection ability of the ejector tube to the air has become the research focus of R&D designers. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an ejec...
