Air ventilation and deodorization integrated equipment for toilets and use method of air ventilation and deodorization integrated equipment

Abstract

The invention relates to an air ventilation and deodorization integrated equipment structure for a toilet. The air ventilation and deodorization integrated equipment structure comprises an air supply outlet, an air return inlet, a low-efficiency filter screen, a medium-efficiency filter screen, a total heat exchanger, a nanometer water ion sterilization and purification module, an exhaust outlet, an air inlet, an infrared human body sensor, a controller, an air supply fan, an exhaust motor, a first adjusting valve, a second adjusting valve, a cavity and a supporting frame. The infrared human body sensor is used for sensing the dynamic state of people flow in the toilet, the start-stop state of the draught fan and the adjusting valve are adjusted, operation of a one-way flow internal circulation mode and a two-way flow external circulation mode is achieved, and the toilet deodorization problem is solved; the fan is adjusted to start and stop by sensing the flow of people in the toilet, and the energy-saving property is considered.

Description

technical field [0001] The invention relates to the technical field of energy-saving ventilation equipment, in particular to an integrated air ventilation and deodorization equipment for toilets and a method for using the same. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, people's requirements for a hygienic environment are getting higher and higher, and the toilet odor problem is one of the main factors affecting people's environmental comfort. The harmful gases such as ammonia and hydrogen sulfide contained in the odor not only have a peculiar smell, but also have strong toxicity, which directly affects people's daily life and physical and mental health. [0003] At present, there are three main methods to control the odor of toilets: open windows regularly for ventilation, which is the cheapest method, but if the outdoor air is polluted, it will affect the air quality in the toilet.

AI Technical Summary

Problems solved by technology

[0003] At present, there are three main methods to control the odor of toilets: open windows regularly for ventilation, which is the cheapest method, but if the outdoor air is polluted, it will affect the air quality in the toilet. In cold winter, Opening windows for ventilation will significantly reduce the indoor air temperature, and people's thermal comfort is poor;

[0004] Install exhaust fans on windows or walls. This method is relatively cheap, but the deodorization effect in the toilet is poor, and the outdoor cold air will also enter from the exhaust fan position to reduce the indoor temperature;

[0005] The fresh air system is used for air exchange. By installing a heat exchanger, the effect of controlling the odor without significantly reducing the indoor air temperature can be achieved. This method has the best effect on controlling the odor in the toilet, but there are two problems: one is the need The cost of installing a suspended ceiling is relatively high, and it is suitable for toilets in large public buildings; second, it does not have the functions of sterilization and deodorization, and the bacteria in the air in the toilet cannot be removed, and the gas discharged to the outside contains a lot of odor
