Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a wind direction changing device for an air conditioner.

(B) Prior Art An example of the structure of a wind direction changing device in a conventional air conditioner is disclosed in Japanese Utility Model Publication No. 57-35802. This includes an air passage for the outlet formed by the outer wall of the drain pan installed below the heat exchanger and a wind guide plate, and a wind direction change frame equipped with a wind direction change blade at the lower end of the wind guide plate. The lower part of the body was fixed. By changing the direction of the wind direction changing blades, the direction of the wind discharged from the passage could be changed.

(c) Problems to be solved by the invention In a wind direction changing device having such a structure, the upper piece of the wind direction changing frame is not fixed to the main body and is located within this ventilation passage, so when the blades are moved, However, this upper piece also had the disadvantage that it was easy to move and the blades were difficult to operate.

Furthermore, since the upper piece of the air direction changing frame body is located within the air passage, there is a risk that this will create resistance to the wind flowing within the passage and reduce the amount of air discharged.

The present invention is aimed at reliably fixing the wind direction changing frame mounted on the air passage, making it easier to operate the changing blades, and suppressing a decrease in the amount of air discharged.

(d) Means for solving the problem In order to achieve this objective, the present invention consists of an air passage at the outlet by an outer wall of the drain pan and a wind guide plate, and a frame body incorporating wind direction changing blades. The upper part fits into a recess in the outer wall of the drain pan, and the lower part of this frame is fixed to the lower end of the wind guide plate.

(E) Function The device of the present invention comprises a drain pan and a wind guide plate to form an air passage at the outlet, and the upper piece of the frame body in which the wind direction changing vane is incorporated is fitted into the recess of the drain pan. The lower piece is fixed to the end of the wind guide plate, and the direction of the wind discharged from the air passage is changed by the wind direction changing vane.

(F) Embodiment In FIG. 1, 1 is an indoor unit of a separate air conditioner, and this unit is installed on an indoor wall. 2 is an indoor heat exchanger, 3 is a cross flow fan, and the rotation of this fan draws indoor air into the air passage 6 through the intake port 5 of the front panel 4.
It is designed to lead to. 7 is a wind guide plate located behind the cross flow fan 3, and a frame 8
The lower end 9 of the wind guide plate 7 is provided with a vertical piece 10 extending downward and a horizontal piece 11 extending rearward. This vertical piece 10
An engagement hole 12 for a wind direction changing frame body (described later) is formed in. Reference numeral 13 denotes a drain pan of the heat exchanger 2, and this drain pan is composed of a receiving part 14 for receiving drain water dripping from the heat exchanger 2, and a wind guide member 15 attached to the lower surface of the receiving part 14. This member 15 is molded from styrofoam, and the rear edge of this member 15 is located in front of the cross flow fan 3 to serve as a vortex forming portion.
Reference numeral 16 denotes a recess formed in the front edge of this member into which the upper piece of a wind direction changing frame (described later) is fitted. In this way, the cross flow fan 3, the wind guide plate 7, and the drain pan 13 are arranged, and the outer wall of the drain pan 13 and the wind guide plate 7 constitute the air passage 6 of the outlet.

Reference numeral 17 denotes a wind direction changing frame body, which is a lower end portion 9 of the wind guide plate 7.
a lower piece 18 positioned in the recess 16 of the drain pan 13, an upper piece 19 positioned in the recess 16 of the drain pan 13, a center piece 20 positioned between the two pieces 18 and 19, and left and right ends 21.
and a support piece 22. The front edge 23 of the upper piece 19 and the front edges 24 and lower edges 25 of the left and right ends 21 are provided with tapered surfaces, so that the edges of the discharge ports (described later) of the front panel 4 can be easily fitted. There is. An engaging pawl 27 is formed on the rear edge 26 of the lower piece 18, and when this pawl is fitted into the engaging hole 12 of the wind guide plate 7, the frame 17 is temporarily fixed to the wind guide plate 7. . 28 is the lower piece 18 and the center piece 20
A large number of these blades 28 are arranged in the left and right direction of the frame 17 and are connected to each other by connecting rods 29. 30 is a horizontal blade, and a support shaft 31 is rotatably attached to the tip of the support piece 22. Note that this horizontal blade is moved by a motor (not shown).

Reference numeral 32 denotes a discharge port formed in the front panel 4, and the peripheral edge of the discharge port 32 is fitted into the tapered surfaces of the upper piece 19, the front edge 24, the lower edge 25, and the lower piece 18 of the frame 17, respectively.

Incidentally, as shown in FIG. 2, mounting portions 34 and 35 having screw holes 33 are formed in a part of the lower piece 18 of the frame 17 and the lower edge of the opening 32 of the front panel 4, respectively. The frame body 17 and the front panel 4 are fixed to the frame 8.

When assembling such a heat exchange unit 1, the upper piece 19 of the frame 17 is applied to the recess 16 of the drain pan 13, and the air guide plate 17 of the frame 8 is
Fitting the engaging claw 27 of the frame body 17 into the engaging hole 12 of the
Thereafter, the front panel 4 is applied from the front of the frame 8, and the peripheral edge of the opening 32 is fitted to the edge of the frame body 17.

When the heat exchange unit 1 is assembled in this way, the upper piece 19 of the frame 17 is fitted into the recess 16 of the drain pan 13, and the outer wall of the drain pan 13 and the surface of the upper piece 19 are connected above the air passage of the outlet. The wall has a smooth curved surface. Further, the guide plate 7, the lower piece 18 of the frame body 17, and the lower edge of the opening 32 of the front panel 4 are fitted, so that the lower wall of the air passage of the outlet has a smooth curved surface. In this way, the resistance of the air discharged from the air passage 6 is kept low.

Moreover, since the upper piece 19 of the frame 17 is fitted into the recess 16 of the drain pan 13 and the frame 17 is securely fixed between the drain pan 13 and the frame 8, when the wind direction changing blade 28 is moved from side to side. , the upper piece 19 of the frame body 17 is prevented from moving.

(g) Effects of the invention As detailed above, according to the invention, the air passage at the outlet is constructed of the outer wall of the drain pan and the wind guide plate, and the upper piece of the frame in which the wind direction changing blade is incorporated is connected to the drain pan. Since the lower piece is fitted into the concave portion and fixed to the end of the wind guide plate, the inner wall of the air passage of the outlet becomes a smooth curved surface, and the resistance of the wind flowing inside this air passage can be suppressed to a small level.

In addition, the upper part of this frame is fitted into the drain pan,
Since the lower part is fixed to the lower end of the wind guide plate and the periphery of the frame body is engaged with the main body, when the wind direction changing blade is moved from side to side, the distortion of the periphery of the frame body is suppressed to a small extent, making it easier to operate the blade. I can do it.
