Method for sterilizing and purifying air exhausted into automobile by automobile air conditioner and filter element assembly

Abstract

The invention relates to a method for sterilizing and purifying air exhausted into an automobile by an automobile air conditioner. Before air output by an air conditioner air inlet channel enters an air conditioner filter element or after the air is exhausted by the air conditioner filter element, the air is sterilized by ultraviolet rays, and harmful substances in the air are decomposed by a photocatalyst filter screen. An air conditioner filter element assembly comprises an air conditioner filter element, the air inlet end or the air outlet end of the air conditioner filter element is connected with a sterilization and purification module; the sterilization and purification module is provided with an annular frame, a through opening defined by the frame is connected with the air inlet orthe air outlet of the air conditioner filter element, a plurality of ultraviolet LED lamps are installed on the inner side of the frame, and a photocatalyst filter screen is fixed to the two end surfaces of the frame, and shields the through opening defined by the frame. Air exhausted into a room by an air conditioner can be sterilized and purified through ultraviolet rays and the photocatalyst filter screen, and the air becomes cleaner after being filtered by the air conditioner filter element. The purposes of sterilization and purification can be fully achieved by the filter element assembly.

Description

technical field [0001] The invention relates to an air conditioner purification technology, in particular to a method for sterilizing and purifying air discharged from an automobile air conditioner into the interior of the vehicle and a filter element assembly. Background technique [0002] The ventilation principle of automobile air conditioning is that the fan sucks the external air into the air-conditioning inlet, passes through the evaporator box and the air-conditioning filter element, and then enters the compartment along the air supply duct and through the air outlet in the car. The main function of the air conditioning filter element is to filter the impurities contained in the air, such as tiny particles, pollen, bacteria, industrial waste gas and dust, etc. The effect is to prevent these pollutants from entering the air conditioning system, so as not to endanger the health of the people in the car. For car air conditioners, the air conditioner filter element is the...

AI Technical Summary

Problems solved by technology

The air-conditioning filter element installed in the car air conditioner can purify the incoming air to a certain extent, but the shortcomings are: 1. Due to the change of seasons, the air-conditioning system is affected by temperature difference and condensed water, and there is humidity, which is easy to breed bacteria. It is difficult for the filter element to kill the bacteria in the system; 2. It is difficult for the air conditioner filter element to sterilize and degrade the air discharged from the outside into the car; 3. After a period of use, if the air conditioner filter element is not replaced in time, it will become a A source of pollution; 4. The compartments of new cars often have peculiar smells and may contain substances harmful to the human body. The air conditioner only discharges air into the car through the air conditioning filter element, so it is difficult to quickly eliminate the peculiar smells in the compartments
