[Effect]

The wind direction changing device in this invention switches the blowing passage to the front part and the upper part by interlocking the decorative board and the single first wind direction changing plate.
The blowing passage can be changed by the first wind direction changing plate to make the flow of the blowing air smoother, and even if the deflection angle is increased, the resistance of the blowing air can be reduced, and the second wind direction changing plate can be rotated. By doing so, the blowing direction can be finely adjusted in the vertical direction when blowing to the front part.

〔Example〕

An embodiment of this invention is shown below in Figures 1 to 5.
The diagram will be explained.

In Figures 1 to 5, 1 is a main body case of a floor-standing indoor unit, 2 and 3 are an air inlet and an air outlet formed at the front center and upper part of the main body case 1, and 9 is an air outlet for this air outlet. This is a single first wind direction changing plate installed inside the outlet 3, and this wind direction changing plate 9 is formed in an arc shape in cross section, and a decorative board 10 is disposed opposite to the outside of the first wind direction changing plate 9. The first wind direction changing plate 9 and the decorative plate 10 are pivotally supported within the main body case 1 by a link mechanism 11 so as to rotate in conjunction with each other. 5 is a heat exchanger, 6 is a blower, 7 is a heat insulating casing, and these are the seventh
It has almost the same configuration as the conventional one shown in FIGS. Further, 12 is a support shaft of the decorative board 10, and 13 is a first
It is a support shaft of the wind direction changing plate 9, and these support shafts 12,
13 are connected by the link mechanism 11, which includes arms 14, 15 and a connecting rod 16. 17 is a plurality of second wind direction changing plates, and 18 is a support shaft that pivots the second wind direction changing plates 17 in the air outlet 2 so as to be rotatable independently. Reference numeral 19 denotes a blow-off nozzle provided on the upper downstream side of the blower 6, and the nozzle 19 and the heat insulating casing 7 form a ventilation path 8 that communicates the blow-in port 2 with the blow-off port 3. 20 is an electric motor for driving the blower 6, and this electric motor 20
is attached to the base 22 of the main body case 1 by the fixture 21.
is fixed. Reference numeral 23 indicates electrical components stored in an electrical component box 24 provided in the main body case 1, 25 indicates a remote control device that commands the operation of the air conditioner, and 26 and 27 indicate front parts provided in the air outlet 3. , which is the blowing passage in the upper part.

Next, the operation of the wind direction changing device of the embodiment configured as above will be explained. When an operation command is given to the air conditioner by the remote control device 25, the blower 6 is rotated by the rotation of the electric motor 20, indoor air is sucked from the air intake port 2, and the air is heated by the heat exchanger 5. Heat is exchanged with warm air and cold air during cooling, and the air is blown into the room from the air outlet 3.

By the way, in order to equalize the indoor temperature and improve the air conditioning effect, it is necessary to blow warm air downward during heating and cool air upward during cooling to create wind flow. It is also required that the air be blown diagonally upward. Therefore, during heating, the decorative board 10 is rotated upward as shown in FIGS. 1 and 4. As a result, the decorative plate 10 rotates around the support shaft 12, so rotational force is transmitted to the arm 14 via the arm 15 connecting rod 16, and the upward blowing passage 27 is blocked by the decorative plate 10. At the same time, the first wind direction changing plate 9 rotates in the solid line shape in FIG. Warm air is smoothly guided forward from the air outlet 3, and the warm air is blown out forward. At this time, by rotating the second wind direction changing plate 17 about the support shaft 18, the warm air can be blown out forward or diagonally upward and forward according to the user's preference.

In addition, during cooling, as shown in FIG. 5, by rotating the decorative plate 10 downward, the link mechanism 1
1 causes the first wind direction changing plate 9 to rotate forward, and the decorative plate 10 closes the blow-off passage 26 to the front part, and forms a blow-off passage 27 to the upper part. The cold air heading towards the first wind direction change plate 9
It is smoothly guided and blown out.

In addition, during cooling, depending on the user's preference, the front air outlet as shown in FIGS. 1 and 4 mentioned above may be used, and the
Cold air can also be blown diagonally upward and forward by the wind direction changing plate 17.

In the above embodiment, when blowing air to the front part, the wind direction changing plate 9 and the decorative plate 10 are linked by the link mechanism 11 to close the blowing passage 27 to the upper part.
Second wind direction changing plate 17 in the blowout passage 26 to the front part
The case where the blown air is finely adjusted diagonally upward has been described, but this invention, as shown in FIG. Air outlet passage 2 to the front
When the airflow direction changing plate 6 is not in use, the second wind direction changing plate 17 is made invisible from the outside, thereby improving the appearance without impairing the design.

In addition, in the above embodiment, the plurality of second wind direction changing plates 17 are provided so as to be rotatable independently, but this invention can be applied even if a single rotatable second wind direction changing plate is provided. A similar effect can be obtained.

[Effect of idea]

As explained above, the air direction changing device according to this invention works by interlocking the decorative plate that blocks the air outlet passage and the single first wind direction changing plate that changes the air outlet passage, thereby allowing air flow to the front part provided at the air outlet. Since the blowout passage and the blowout passage to the upper part are switched, the flow of the blowout air is made smooth by the first wind direction changing plate, and even if the change angle is increased, the resistance of the blowout air can be reduced, so that the blowout air is The air volume loss can be reduced, and since the second wind direction changing plate is provided in the blowout passage to the front part so as to be rotatable in the vertical direction, by rotating the second wind direction changing plate,
When blowing air toward the front part, there is an effect that the blowing direction can be finely adjusted in the vertical direction according to the user's preference.
