Kitchen flue

Abstract

The invention discloses a kitchen flue. The kitchen flue comprises an air outlet pipe, an installing plate, a cover plate, a spring and a support. The air outlet pipe is installed on the installing plate. The installing plate is provided with a through hole. The through hole is communicated with the air outlet pipe. The cover plate is hinged to the installing plate. The spring is arranged between the air outlet pipe and the cover plate. The support is arranged on the installing plate. The support is provided with a fixed pulley. A hook is arranged at an outer part of the air outlet pipe. A stay cord is arranged on the cover plate. The stay cord passes by the fixed pulley and reaches to the hook. The cover plate is utilized to control opening and closing of the kitchen flue and felt pads as sealing pads are utilized for sealing of a door and a flue mouth, and thus sealing effects and appearance are good. A control process of opening and closing of a sliding door in the kitchen flue is realized only by the coordination of the stay cord and the spring for reverse pulling. The control process does not influence normal operation of a smoke ventilator and thus solving the problem of flowing back of smoke in the kitchen flue.
