When, since the first wind deflector 70 is by being located at two the first wind-guiding faces 71 of about 70 two sides of the first wind deflector to air outlet 12
Gas flow in outlet air region is adjusted, therefore while meeting the adjustment demand to gas flow, reduces first and leads
The volume of aerofoil 70 can reduce the volume at air conditioner wind outlet 12.The area of second wind-guiding face 81 is larger, can be to through going out
The gas flow that air port 12 is flowed out sufficiently is adjusted, and the wind effect of the second wind deflector 80 is improved.
The technical solution of the utility model is had been described in detail above with reference to the accompanying drawings, by the technical solution of the utility model,
In air conditioner air-out, high-temperature gas (being electrically heated the gas of device heating) upside is distributed with medium temperature gas and (is not added
The gas of heat), since the density higher temperatures gas of medium temperature gas is big, high-temperature gas can be hindered to rise, and then make high-temperature gas
Lower height can be blown to downwards, achieve the effect that " warm foot ", in air conditioner heat-production, the distribution of room temperature is more uniform,
Promote the comfort level of user.Enable high-temperature gas to flow to by the interaction between medium temperature gas and high-temperature gas simultaneously to lean on
The flow losses of subaerial height, gas are smaller.
