Description

Purification module and air conditioner indoor unit

technical field

The present application relates to the technical field of air purification, for example, to a purification module and an air conditioner indoor unit.

Background technique

Existing air purification technologies mainly include adsorption, room temperature catalytic oxidation, etc. Among them, the adsorption method uses adsorbent materials such as activated carbon to adsorb volatile organic compounds and harmful gases in the air, but it cannot decompose these pollutants. After the adsorption is saturated, it will become a new pollution source and release pollutants again. It is necessary to replace the adsorbent regularly to maintain its purification performance; In addition, the adsorption method cannot sterilize and disinfect, and bacteria, viruses and other pathogens will breed on the surface after long-term use, which is not conducive to air purification. Catalytic oxidation at room temperature uses strong oxidants such as potassium permanganate to oxidize and decompose pollutants in the air, but its decomposition efficiency is low and requires a large amount of oxidants, which cannot be adapted to the existing air-conditioning structure; as the use time increases, the oxidation effect becomes less Poor, requires periodic replacement to maintain removal.

In addition, photocatalyst purification technology is mainly used in indoor air pollution purification, vehicle interior pollution purification, automobile exhaust purification, industrial and domestic wastewater treatment, oil pollution treatment, port waste oil treatment, nuclear power plant heavy water purification and other fields. In terms of indoor air purification, it is mainly used as wall coating or furniture coating to play a purification function. This application method is relatively poor in purification effect.

The catalyst plate 20 is arranged in the hollow portion 101 and is in an arc shape to ensure a stable connection with the frame body 10 and to match the heat exchanger 80 . Vent structures 201 are constructed on the catalyst plate 20 , and the vent structures 201 are arranged in a matrix. The air flows through the ventilation structure 201 and fully contacts with the catalyst plate 20 to improve the purification effect. Moreover, the ventilation structure 201 can also overcome the circulation resistance of the existing catalytic plate 20 to the airflow when purifying the air. The air purified by the purification module flows through the heat exchanger 80, exchanges heat with the heat exchanger 80, and then blows out from the air outlet of the air conditioner indoor unit to improve the cleanliness of the indoor air, thereby improving user experience. In addition, installing a purification module on the air intake side of the heat exchanger 80 also helps to reduce the dust and bacteria in the air from adhering to the outer surface of the heat exchanger 80, thereby improving the heat exchange efficiency between the heat exchanger 80 and the air.

Optionally, the frame body 10 is configured with a groove 102 on the inner side wall of the hollow portion 101 , so that the edge of the catalyst plate 20 is embedded in the groove 102 and fixed.
