[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for mounting wind direction changing blades of an air conditioner embedded in a wall or the like.

[0002]

[Prior art]

 Generally, a wall-embedded air conditioner 51 is provided with a heat exchanger 53, a blow-out grill 54, a fan 55, an air guider 56, etc. inside a underframe 52 having an opening on the indoor side as shown in FIG. Auxiliary pipes 57 that lead out from the heat exchanger 53 are provided on the upper part of the frame 51, and these are inserted and fixed to the existing rectangular installation frame 59 on the wall 58, and a suction part 60 that covers the entire interior surface of the room A front grill 62 having a blow-out portion 61 is provided. Then, the indoor air is sucked from the suction section 60 and passed through the heat exchanger 53, and after exchanging heat with the refrigerant of the heat exchanger 53, the air is blown again to the indoor side from the blowout section 61 to perform air conditioning. The direction of the blown airflow is changed by a plurality of left and right blades 63 provided on the blowout grill 54 and upper and lower blades 64 provided on the front grille 62.

However, the left and right blades 63 are connected to each other by the connecting bars 65 as shown in FIG. 4, and are vertically engaged with the water pan 66 of the outlet grill 54 and the shafts 68 and 69 provided on the lower frame 67. It was set up together. Further, the lower frame 67 of the blow-out grill 54 has a flat plate shape with a small depth so that it can be removed during maintenance of the fan 55 and the like.

[0004]

[Problems to be solved by the device]

 In such a conventional wind direction changing blade mounting structure, the lower frame 67 of the outlet grill 54 is easily deformed in the vertical direction, and the left and right blades 63 are disposed between the shaft portion 68 of the water tray 66 and the shaft portion 69 of the lower frame 67. Since the left and right blades 63 are easily attached to each other because they are engaged with each other in the vertical direction, the engagement and disengagement of the plurality of left and right blades 63 are performed at the same time, which makes the work difficult. It was

Further, when the left and right blades 63 assembly of the outlet grill 54 is mounted on the air conditioner 51, there is a drawback that the left and right blades 54 fall off from the outlet grill unless careful assembly is performed. Further, even when the air conditioner 51 is packed, extra work such as fixing with tape or the like is required to prevent the left and right blades 54 from falling off during transportation. If the number of vertical bars 70 that connect the water tray 66 and the lower frame 67 is increased to prevent deformation of the lower frame 67, the wind direction change rate will decrease, and the dew performance will deteriorate due to the air flow being squeezed out. There was also the problem of doing.

In view of the above problems, the present invention aims to provide a mounting structure for a wind direction changing vane that is easy to assemble and does not fall off during handling.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a pair of left and right blades with scissor-shaped upper engaging portions that extend to the upper portions thereof and have locking portions, and one end of which is open. Parts are provided. Further, according to the present invention, a plate stopper is provided on the blowout grill and the shaft portion of the lower frame.

[0008]

[Action]

 Therefore, when inserting and fixing the left and right blades into the axis of the outlet grille, it is sufficient to insert the blades horizontally from the front, and the direction of deformation of the lower frame is different, which facilitates the work. In addition, since the blowout grill and the plate stoppers on the shaft of the lower frame interfere with the upper and lower engaging parts of the left and right blades to restrict movement, the left and right blades do not fall off due to deformation of the lower frame.

Reference numeral 13 is an auxiliary pipe that is led out from the heat exchanger 11 and is provided above the underframe 7. Reference numeral 14 denotes upper and lower blades provided at the outlet 6 of the front grill 4, and 15 denotes left and right blades provided at the outlet grill 12.

Next, the structure of the outlet grill 12 and the mounting structure of the left and right blades 15 will be described. As shown in FIG. 2, the outlet grill 12 includes a water pan 16 that extends horizontally in a container shape, a lower frame 17 that extends horizontally in a lower part in an L-shaped cross section in parallel with the water pan 16, and a water pan. The side wall portion 18 is formed by vertically connecting both end portions of the portion 16 and the lower frame 17, and the central wall portion 19 is formed by vertically connecting the water tray portion 16 and the central portion of the lower frame 17. Further, a drain connection port 20 for discharging drain water accumulated in the water tray 16 is provided below one end of the water tray 16, and a plurality of upper support shafts are evenly spaced along the lower entire length thereof. 21 is provided. Further, the lower frame 17 is also provided with a plurality of lower support shafts 22 corresponding to the upper support shafts 21 on the entire upper side thereof.

The upper support shaft 21 and the lower support shaft 22 are provided with disk-shaped plate stoppers 23 and 24, respectively.

On the other hand, the left and right blades 15 are provided with an engaging portion 26 extending upward from a front portion of a flat blade main body 25, and a scissor-like upper engaging portion 27 opening to the rear side. A similar lower engaging portion 28 is provided extending to the lower portion. The upper engaging portion 27 and the lower engaging portion 28 are provided on the same vertical line. Further, a protruding connecting bar insertion portion 29 is provided at the rear portion of the blade main body 25.

Then, the upper engaging portions 27 of the left and right blades 15 are engaged with the upper supporting shafts 21 of the outlet grill 12, and the lower engaging portions 28 are engaged with the lower supporting shafts 22, so that the plurality of left and right blades 15 are engaged. The left and right blades 15 are fixed to the outlet grill 12 by providing a pair of left and right connecting rails 30 in the connecting rail insertion portions 29 of the left and right blades 15. That is, a plurality of left and right blades 15 are connected to each other around the central wall portion 19 of the outlet grill 12 by a connecting bar 30, and are fixed so as to be rotatable at a predetermined angle around an upper support shaft 21 and a lower support shaft 22. -ing

When the air conditioner body 1 is operated, the indoor air is introduced into the heat exchanger 11 through the suction port 5 of the front grill 4 and exchanges heat with the refrigerant in the heat exchanger 11, and then the blowout grill. A plurality of left and right blades 15 of 12 and the upper and lower blades 14 of the front grille are guided and blown out in an arbitrary direction to perform air conditioning in the room.

As described above, in the left and right blades 15, the upper engaging portion 27 and the lower engaging portion 28 may be inserted from the front into the upper supporting shaft 21 and the lower supporting shaft 22 of the blowing grill 12, respectively.
