Kitchen air conditioner exhaust system

The invention discloses a kitchen air conditioner exhaust system, and relates to the technical field of kitchen air conditioners, the kitchen air conditioner exhaust system comprises an exhaust box body, an oil filter assembly and an air filter assembly, the bottom end of the exhaust box body is connected with a communicating pipe, the outer side of the bottom of the communicating pipe is connected with an air suction assembly, and the oil filter assembly is arranged at the bottom end of the left side of the exhaust box body. When air needs to be exhausted in a kitchen, the electric control valve in the air suction pipe at the bottom end of the vacuum box is opened, and air in the kitchen is sucked into the vacuum box from the air suction pipe due to the influence of air pressure difference; by means of the design, the vacuum box can have high suction force in the process that the vacuum box is opened for air suction, the equipment can rapidly suck away gas pervading in a kitchen in the exhaust process, and w
