Description

[Detailed description of the invention] The present invention relates to an improvement in the blowing structure of an air conditioner equipped with a fluidic element in the blowing part, and the blowing direction of air that has been cooled (heated) after passing through a heat exchanger is One of the purposes is to improve the pleasant sensation of dust by switching the air conditioner upward and downward depending on the temperature of the intake air during cooling and heating, or when blowing out or blowing out air, using the vertically changing blades that constitute the fluid element.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, A is an indoor unit main body constituting a separate air conditioner, each of which is equipped with a suction section 1, a heat exchanger 2, a fan 4, and a blowout section 3 having a pair of blowout surfaces whose tips expand in the vertical direction. ing.

Reference numeral 5 denotes a changing blade provided in the blowing section 3, which is periodically rotated back and forth within a certain angle by a stepping motor 7 via a speed reduction device 6, as shown in FIG.

Further, the stepping motor 7 reverses the changing blades 5 depending on the heating and cooling conditions, and periodically rotates them back and forth within a certain angle in each state.

In the above configuration, during heating, as shown in FIG.
It is mainly blown out downward within a certain angle α of the blowing part 3.

Further, during cooling, the changing blade 5 is reversed approximately 180 degrees by the stepping motor as shown in FIG. 2, and the fan 4 is driven in this state.

The indoor air X sucked in by the fan 4 passes through the heat exchanger 2 from the suction part 1, becomes low-temperature air Z, and is blown upward by the changing blade 5 mainly within a certain angle β of the blowing part 3.

Therefore, the wind direction during cooling or heating can be changed according to the rotation of the stepping motor 7, and unlike conventional structures in which the wind direction is changed by applying wind to the changing blades, the changing blades 5 You can smoothly switch up and down by rotating.

Furthermore, since the wind direction is switched using the pressure difference generated by the changing blades 5, it is quiet and the air blowing efficiency does not decrease.

Furthermore, ideal air conditioning can be achieved by operating only the variable blades 5.

In this embodiment, the change blade 5 is configured to be reversed by a well-known control circuit in response to switching between cooling operation and heating operation, but when rapid cooling is required, etc. This can be done by inverting the changing wing 5 in the same manner as described above and using known techniques.

As is clear from the above embodiments, the air blowing structure of the air conditioner according to the present invention is provided with a blowing section equipped with a blower, and this blowing section is connected to a pair of discharging surfaces extending in the vertical direction, and approximately It consists of a changing blade located in the center that is curved in one direction, and is further equipped with a drive device that reverses the changing blade, so that it can be used for cooling or heating without sacrificing the quiet wind direction changing effect unique to fluid elements. It allows for effective ventilation at times, and simplifies the structure required to change the wind direction.
It has various advantages.
