Air supply device of floor air conditioner

The invention discloses an air supply device of a floor air conditioner. The air supply device comprises at least two annular air guide assemblies. The middles of the annular air guide assemblies are communicated with one another, a front opening and a rear opening are respectively formed in each annular air guide assembly, each annular air guide assembly is an individual assembly, the rear opening of each annular air guide assembly is used as an air inlet, the front opening of each annular air guide assembly is used as an air outlet, the annular air guide assemblies are sequentially arrayed in the front-back direction, front-back through air channels are formed in the middles of the annular air guide assemblies, an annular heat-exchange air channel is formed between each two adjacent annular air guide assemblies, and the air outlet of the rear-end annular air guide assembly of each two adjacent annular air guide assemblies extends into the through air channel which is limited by the front-end annular air guide assembly of the two adjacent annular air guide assemblies. The air supply device of the floor air conditioner has the advantages that the air supply device is applied to the air conditioner, the structure of each annular air guide assembly can be flexibly controlled according to air supply requirements, the various annular air guide assemblies with the different structures can be conveniently machined, flowing of air flow can be effectively stabilized while the air supply speed can be high, and the air supply performance of the air supply device is improved.
