When the ambient temperature is too low or too high, it can adjust the temperature of the indoor air to provide users with a suitable indoor environment and effectively improve the air conditioner. Quality of life of users.

However, because the current air conditioners only circulate the indoor air to heat or cool down when heating or cooling, and the user will close the door of the living room at the same time in order to maintain the indoor temperature, so that the indoor air quality will be reduced. It will gradually deteriorate, which will adversely affect the user's health. In particular, in recent years, air pollution has been increasing day by day, especially in the winter heating season, and people are reluctant to open windows for ventilation. In this way, the indoor air quality will become worse and worse, and the oxygen content will be lower and lower, which will affect the health of the body.

There is also the problem that the current air-conditioning interior equipment cannot introduce outdoor air. Foreign developed countries, such as Germany, have introduced the method of large-scale air conditioning in factories and theaters and the introduction of fresh air devices into households after refinement and miniaturization. However, the cost is too high. Generally, the price of fresh air devices suitable for households is 4,000, 5,000, or even tens of thousands, which is more expensive than air conditioners and subverts the general Chinese people's concept of cost-effective consumption.

The air outlet 223 of the fan module 220 is provided with an air outlet grid 225 to prevent dust or mosquitoes from entering the fresh air device 200, polluting or destroying the internal structure of the fresh air device 200, and preventing the reduction of the effect of the fresh air device 200 for fresh air.

As shown in FIG. 8 and FIG. 9 , the purification module 230 is arranged at one end of the fresh air inlet pipe 213 located outdoors, and uses strong electric field dielectric technology to purify the air delivered to the room. In this embodiment, the purification module 230 is arranged outdoors and does not occupy indoor space, which simplifies the indoor installation of the air conditioner. In addition, the purification module 230 is set at one end of the fresh air inlet pipe 213 located outside, so that dust cannot enter the fresh air inlet pipe 213, so the interior of the fresh air inlet pipe 213 can be kept clean for a long time, avoiding the need for regular cleaning by the user The problem of the fresh air inlet duct 213 improves the user experience.

The above purification module includes: an IFD purification device 232 , a housing 231 , a first filter 234 and a second filter 235 . The casing 231 has a cylindrical shape. The housing 231 is connected to the outdoor end of the fresh air inlet pipe, its axis coincides with the axis of the fresh air inlet pipe, and its diameter is larger than that of the fresh air inlet pipe. Inside the housing 231 is formed a housing chamber for installing the IFD purification device 232 , and the housing chamber communicates with the fresh air inlet pipe 213 . The end of the casing 231 away from the fresh air inlet pipe 213 is provided with an opening for air intake, and a rainproof cover 233 protruding outward from the opening is provided on the top edge of the opening. The rainproof cover 233 is used to prevent rainwater from entering the housing 231 in rainy days and affecting the normal operation of the IFD purification device 232 . In this embodiment, the rainproof cover 233 is an arc-shaped surface.

The IFD purification device 232 is arranged in the accommodating cavity, and it includes: a body and a plurality of electrode sheets, the body is made of a dielectric material, and forms a plurality of microchannel structures along the direction of movement of the air flow; a plurality of electrode sheets are arranged in a plurality of microchannels Inside the structure, it cooperates with the dielectric material to generate a strong electric field. IFD is a kind of dust removal technology, which is the most advanced and most efficient technology among the existing dust removal technologies, and it is extremely effective. A strong electric field using a dielectric material as a carrier. The dielectric material forms a honeycomb hollow microchannel, and the dielectric wraps the electrode sheet to form a strong electric field in the channel, which exerts a huge attraction on the charged particles moving in the air, and can absorb almost 100% of the air while only producing the minimum airflow resistance. Moving particles are especially effective in removing particulate pollutants such as PM2.5. Using the purification module 230 of the above-mentioned FID purification device can greatly reduce the PM2.5 particles in the air and effectively improve the quality of the outdoor air sent into the room in the smog-ravaged weather.

A first filter 234 is disposed between the bottom edge of the rainproof cover 233 and the edge of the opening for filtering the air delivered to the room. The side of the IFD purification device 232 facing the opening of the housing 231 is detachably installed with a second filter 235 for further filtering the air delivered to the room. Wherein, the aperture of the first filter 234 is larger than that of the second filter 235 . In this embodiment, the first filter 234 is used to filter large particles of dust, and the second filter 235 is used to filter small particles of dust, and both layers of filters use physical methods to filter dust. The IFD purification device 232 uses a strong electric field to remove extremely fine dust particles such as PM2.5. The purification module 230 of this embodiment performs three times of filtering and cleaning the air entering the indoor unit, which includes two different purification methods of physical filtration and electric field filtration, which can remove most dust particles in the air, so the purification effect is better, ensuring The cleanliness of the air entering the room.

In addition, the purification module 230 can also be filtered by Hypa, which is a high-efficiency filter paper that can filter 99% of fine particles in the air, so as to ensure that the air output by the fan module 220 is clean and avoid secondary pollution.

In the fresh air device 200 of the present utility model, a filter screen 224 and an IFD purification device 232 are installed, which can purify the fresh air entering the room, especially now that air pollution is increasing day by day, and the purified air is sent into the room to improve the indoor air reduce the harm of polluted air to the body.
