Problems solved by technology

Therefore, when the gas flows through the ejector, serious gas turbulence will occur in the ejector, which will affect the smooth passage of the gas and ultimately affect the thermal efficiency of the gas stove.
However, this field has not paid enough attention to this problem. When considering the improvement of the thermal efficiency of gas stoves, almost all of the research and development energy has been put on the structural improvement of the burner, but the structural improvement of the ejector has been neglected. little interest

Embodiment 1

[0024] The ejector 1 embodiment that the present invention proposes, as figure 1 and 2 As shown, the ejector 1 is a double-pipe ejector, and the two pipes supply gas to the inner ring fire and the outer ring fire respectively. The specific manufacturing process of this embodiment of the ejector 1 is as follows: the main part of the ejector 1 is formed by casting molten iron, and then a layer of high-temperature-resistant and smooth-surfaced coating 2 is provided on all the inner walls of the ejector 1 . In the present embodiment, coating 2 is an enamel layer. Due to the setting of the enamel layer, the originally very rough inner wall of the injector 1 becomes relatively smooth.

[0025] The above are only preferred embodiments of the present invention, and other embodiments can be obtained by modifying or replacing certain technical features. For example, it is also possible to provide a high temperature resistant and smooth coating on only a part of the inner wall of the ...

Embodiment 2

[0027] The present invention also proposes an embodiment of a gas stove, which is provided with a burner and an injector. The inner wall of the ejector is partially provided with a high temperature resistant and smooth surface coating. The so-called "partially provided" means that no coating is provided on the inner wall of the injector near the burner. In this way, the high temperature resistance requirement of the coating can be reduced to a certain extent, thereby reducing the manufacturing cost. Specifically, the material of the coating is high temperature resistant paint. The inner wall of the ejector is provided with streamlined protrusions. In addition, a heat insulating device is arranged between the ejector and the burner, so that the requirement for high temperature resistance of the coating can be reduced to a certain extent, thereby reducing the manufacturing cost. Specifically, the heat insulation device is made of heat insulating material.

Abstract

The invention provides an ejector and a gas stove provided with the ejector, wherein the inner wall of the ejector is good in gas guiding effect. According to the ejector, a coating is arranged on at least part of the inner wall of the ejector, wherein the coating is high-temperature resisting and the surface of the coating is smooth. The probability of the occurrence of turbulence of gas can be obviously reduced when the gas flow through the ejector, and then the gas is enabled to flow smoothly.

Description

【Technical field】 [0001] The invention relates to the field of gas stoves, in particular to an ejector. 【Background technique】 [0002] Gas stoves are household stoves commonly used in people's daily life, and gas stoves are mainly stoves that burn with liquefied combustible gas as fuel. The liquefied combustible gas can be natural gas, liquefied petroleum gas, biogas, etc. According to the different types of liquefied combustible gas, gas stoves can be divided into various types, such as liquefied gas stoves, coal gas stoves, natural gas stoves, etc. Of course, gas stoves can also be divided into single stoves, double stoves, single-eye stoves, multi-eye stoves, desktop stoves, embedded stoves, etc. according to their different structures. [0003] The ejector arranged in the gas cooker is an important part of the gas cooker, and its main function is to fully mix the gas and air according to a certain ratio, and deliver them to the burner. The existing ejector is generall...
