Problems solved by technology

[0002] Gas water heaters are generally installed in bathrooms. Although the functions of gas water heaters are becoming more and more abundant and the quality has been greatly improved, they still cannot fully guarantee gas leakage. It will also cause gas leakage. Many reports have reported gas poisoning accidents caused by the gas water heater itself or its installation. Therefore, it is necessary to design a new bathroom ventilation control method to improve the safety of the bathroom.

Abstract

The invention discloses a bathroom ventilation control method based on shutters. The shutters (3) and an exhaust fan (4) are installed on the external wall (1) of a bathroom, and a combustion gas monitoring device is installed in the bathroom; the combustion gas monitoring device comprises an MCU, a combustion gas concentration sensor, a pyroelectric infrared sensor, a shutter angle sensor, a shutter slat angle electric control mechanism, a display screen, a sound-light alerter and a power supply module. After the combustion gas monitoring device is initialized, the MCU monitors the output signals of the pyroelectric infrared sensor and the combustion gas concentration sensor so that ventilation control can be performed. According to the bathroom ventilation control method based on the shutters, the risk caused by combustion gas leakage in the bathroom can be effectively eliminated so that safety is high.

Description

technical field [0001] The invention relates to a bathroom ventilation control method based on blinds. Background technique [0002] Gas water heaters are generally installed in bathrooms. Although the functions of gas water heaters are becoming more and more abundant and the quality has been greatly improved, they still cannot fully guarantee gas leakage. Also can cause gas to leak, have many reports to once report the accident that causes gas poisoning because gas water heater itself or the reason of installation, therefore, be necessary to design a kind of brand-new bathroom ventilation control method, to improve the safety of bathroom. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shutter-based bathroom ventilation control method, which can effectively eliminate the threat caused by gas leakage in the bathroom and has high safety. [0004] The technical solution of the invention is as follows: [0005] ...
