Description

Cabinet air conditioner with air purification device installed

technical field

The utility model relates to a cabinet type air conditioner, in particular to a cabinet type air conditioner equipped with an air purification device.

Background technique

With the aggravation of indoor air pollution, people have higher and higher requirements for indoor air purification. Because ordinary air conditioners are used in a closed environment, the indoor air becomes more and more turbid, which not only cannot effectively remove indoor pollutants, but also creates conditions for the growth of germs and viruses. On the basis that the temperature regulation function of the air conditioner is fully exerted, improving the air quality regulation function of the air conditioner is a main direction of the development of the ordinary air conditioner.

In order to solve the above problems, an air purification device can be installed in the air conditioner to produce a healthy air conditioner with purification function. A common method is to install a filter screen with sterilizing and deodorizing functions at the air inlet of the air conditioner. The filter screen is made of antibacterial and deodorizing materials such as catechin antibacterial agents, silver ions, activated carbon, and air purifiers. Large particles of dust also play a role in killing bacteria in the air and removing odors in the air. However, the method of using the filter screen cannot filter out the smaller particles in the air, and the ability to remove harmful gases in the air is not strong. In addition, in the existing design, photocatalytic bactericidal coatings such as nano-titanium dioxide and zinc oxide are applied to the parts through which the airflow of the air conditioner air duct system passes, such as evaporators, air inlet and outlet covers, etc. The ultraviolet lamp installed in the air conditioner irradiates the bactericidal coating to generate strong oxidizing hydroxyl radicals, degrade organic matter and kill bacteria and viruses to achieve the purpose of purifying the air. The disadvantage is that the process of coating photocatalytic bactericidal coating on each component is complicated, the production efficiency is low, and it is easy to cause the photocatalytic bactericidal coating to not fully exert the purification effect and the purification is not thorough due to the insufficient irradiation range and intensity of the ultraviolet lamp. The effect is poor.
