A kitchen smoke exhaust system and its operation monitoring method

Abstract

A kitchen smoke exhaust system, including a range hood installed in the kitchen, the kitchen has a door and a window, the range hood has a fan, and the outlet of the fan communicates with the public flue through a smoke pipe, and is characterized in that: There is a door sensor used to detect the opening and closing of the door, and a driving mechanism for driving the opening and closing of the window is installed on the window. The range hood has a sound detection module and also includes a controller, which can read the door sensor, the driving mechanism and the sound. The information of the detection module is combined with the speed of the fan to determine whether the exhaust channel is leaking or blocked. The advantages of the present invention are: the controller of the kitchen smoke exhaust system can read the information of the door sensor, the driving mechanism and the sound detection module and combine the fan speed to judge whether the flue is blocked, and use the whistling sound to cooperate with the speed detection and the door and window opening and closing detection Judging whether there is leakage in the smoke pipe can also reduce false alarms, carry out pre-maintenance and maintenance, and improve user experience.

Description

technical field [0001] The invention relates to a central flue system, in particular to a kitchen smoke exhaust system and an operation monitoring method thereof. Background technique [0002] At present, the floors of newly built buildings in cities are generally higher and higher, and are mainly decorated with engineering. Most high-rise residences use indoor range hoods, smoke pipes, check valves and public flues to connect, so that the cooking fumes in the kitchen can be exhausted through the smoke pipes. into the public flue. The traditional range hood is in an open state after installation. The smoke pipe is easily broken by the nail gun when the carpenter is suspending the ceiling during the decoration process. During use, due to the accumulation of oil fume, the oil net is blocked, the check valve cannot be opened or the smoke pipe is loose. Detachment and damage will easily lead to a decline in the smoking effect of the user, and the appearance of the smell of down...

AI Technical Summary

Problems solved by technology

The traditional range hood is in an open state after installation. The smoke pipe is easily broken by the nail gun when the carpenter is suspending the ceiling during the decoration process. During use, due to the accumulation of oil fume, the oil net is blocked, the check valve cannot be opened or the smoke pipe is loose. Detachment and damage will easily lead to a decline in the user's smoking effect, and the appearance of smoke and odor, which will affect the user experience

The existing kitchen exhaust system cannot effectively detect the blockage of the public flue and the leakage of the smoke pipe, and the user cannot detect the operating status of the system in real time
