Gas cooking appliance optimization design evaluation method and test system therefor

Abstract

The invention discloses a gas cooking appliance optimization design evaluation technological method. The gas cooking appliance optimization design evaluation technological method comprises the following steps of (1) selecting a typical sample; (2) establishing a three-dimensional geometrical model of the sample; (3) performing research on sample experimental test: including the steps of a, establishing an experimental system for test; and b, taking experimental test data as a boundary condition, performing analogue simulation on the sample; (4) performing determination and correction on a simulation result based on the actually measured data; (5) applying a verified fuel gas flow and combustion model to all experimental samples to perform verification test and simulation; and (6) guiding design by the analogue simulation. The test experimental system adopted by the method consists of a fuel gas supplying part, a gas cooking appliance performance test part and a control host with a signal conversion module. By adoption of the optimization design evaluation technological method, the combustion working condition, the thermal performance and the smoke emission index of the gas cooking appliance can be rapidly evaluated without producing and manufacturing a gas cooking appliance body, so that the design efficiency and the technological level of the cooking appliance can be improved consequently.

Description

technical field [0001] The present invention relates to the field of gas cookers, and more specifically, relates to a gas cooker optimization design evaluation method and a test system thereof. The method optimizes and evaluates the design level and effect of the gas cooker. Background technique [0002] In recent years, as people pay more and more attention to environmental protection, natural gas as a clean energy is gradually favored by everyone. As gas cookers are the main products of gas appliances, the research on the design technology and energy efficiency level of their burners has also received more and more attention. [0003] Household gas cookers are generally composed of air intake pipes, burners, cooktops, pot supports and frames. As the core of the cooker, the burner is generally composed of an ejector, a nozzle, an air regulating plate, a burner and a fire cover. In the design of the stove, the design of the burner is the most important. Although there are...

Problems solved by technology

This method leads to great differences in combustion performance due to the different experiences of designers, and it takes a lot of time and resources to develop molds and conduct combustion performance test experiments to verify the feasibility of various designs and assumptions. The method is not conducive to the research and development of gas cooker burners

At the same time, the development of molds requires a lot of manpower and material resources, resulting in a huge waste of manpower and funds
