Embodiment Construction
[0034] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.
[0035] The inventor has been engaged in the research on the mechanism and diffusion of oil fume. By establishing the mechanism and diffusion model of oil fume, he proposed the theory of effective negative pressure zone of oil fume. Cooking fumes are mainly composed of four states of matter before they are mixed with air: fuel combustion exhaust, food spills, water vapor and oil gasification, and cracking products. Diffusion of temperature difference, diffusion of pressure difference, and diffusion of concentration difference and density difference will also occur. To suppress the diffusion of oil fume, prevent the escape of oil fume, and reduce the mixing of oil fume and air, a strong negative pressure field is required, which is the effective negative pressure...
