Intelligent air exchanging method and system for bathroom

Abstract

The invention relates to an intelligent air exchanging method and system for a bathroom and aims to solve the problem that discharged bad air returns. The intelligent air exchanging system is characterized in that a squatting pan or pedestal pan exhaust duct with a lower exhaust outlet is arranged on the rear wall of a squatting pan or a pedestal pan, a urinal exhaust duct with a lower exhaust outlet is arranged on the wall above a urinal, and the exhaust ducts discharge air through a main air duct by the aid of a fan controlled by an intelligent controller; the intelligent controller is connected with an air quality sensor in the bathroom, when the air quality measured by the air quality sensor exceeds the standard, the intelligent controller automatically turns on the fan to discharge the air, and when the air quality measured by the air quality sensor conforms to the standard, the intelligent controller automatically turns off the fan to stop the air discharge; or the intelligent controller is connected with a person sensing device, when the person sensing device senses that a person enters the bathroom, the intelligent controller automatically turns on the fan to discharge the air, and when the person sensing device senses that the person leaves the bathroom, the intelligent automatically turns off the fan to stop the air discharge in a delay manner. The intelligent air exchanging system has the advantages that energy conservation is achieved, the polluted air cannot return easily, and high air exchanging efficiency is achieved.

Description

technical field [0001] The invention relates to a toilet air renewal method, in particular to a toilet intelligent air replacement method and system. Background technique [0002] The poor air quality of toilets, especially public toilets, has always been a common technical problem plaguing relevant designers. Usually people rely on increasing the exhaust intensity, prolonging the exhaust time, or even continuously exhausting the air. Through long-term investigations and studies, it has been found that the above-mentioned various exhaust intensity and time will significantly exceed the required methods. The following defects still exist: not only waste Exhaust energy and exhaust equipment, and, in a poorly ventilated environment or weather, it will also cause the discharged polluted air to flow back into the bathroom, which is not conducive to the maintenance of air quality in the bathroom; in addition, the exhaust airflow carries Poor air pollution ability and low exhaust ...
