The type of ion generator 19 can be selected according to actual conditions.

The ionizer 19 generates positive ions and/or negative ions, which on the one hand can kill bacteria in the air, and on the other hand can charge dust or particles in the air, thereby being more easily adsorbed on the purification filter 13. In addition, in the air After the dust or particles are charged, even if the pores of the filter pores are much larger than the dust or the size of the particles of the purification screen 13 (especially by the oppositely charged purification screen 13), they are adsorbed at a very high efficiency. Thus, the pore size of the filter pores of the purification filter 13 can be much larger than the diameter of the dust or particles, thereby greatly reducing the passage wind resistance of the purification filter 13, and ensuring that the refrigeration and heating performance and the air volume of the air conditioner itself are substantially unaffected.

Preferably, the ionizer 19 can be used in conjunction with the purification screen 13. For example, when the ionizer 19 is a negative ion generator, the purification screen 13 may be a positively charged purification screen 13. Thus, the ion generator 19 generates negative ions, so that dust or particles in the air are negatively charged, so that it is more easily adsorbed on the positively charged purification filter 13, thereby increasing the CADR (clean air delivery rate) value.
