- the kitchen equipment shown in FIGS. 20 and 21 is a ladder that expands downward into an exhaust duct 201 that communicates outdoors and stores a fan.
- a canopy-shaped canopy 202 is connected to the ceiling.
- the canopy 202 has no Grease filter that separates and removes tar-like substances mixed with oils and fats and dust from air breeze 203
- Grease separator 220 and other filters are provided.
- Exhaust gas purifier 205 is installed.
- the filter 204 is equivalent to or higher than stainless steel sheet or stainless steel sheet. It is formed of a non-combustible material that has heat resistance and corrosion resistance. Also, as shown in FIG. 22 or FIG. 25, for example, as shown in FIG. 22 or FIG. 25, when the exhaust air 203 flows through, the ⁇ It is formed in a loop-bar structure in which the contraction of the flow occurs. By these redirection or contraction, the fat and oil in the exhaust air 203 is brought into contact with the wall surface to remove more than a predetermined amount of fat and oil.
- the filter 204 is arranged in such a structure that it can be easily attached and detached so that oils and fats adhering to it by being separated and removed can be easily washed and removed.
- a gutter 208 is provided outside the canopy 202 to collect and remove a predetermined amount or more of the separated fats and oils.
