Description

[Detailed description of the invention] This invention relates to the improvement of air conditioners, and in particular, the support frame and the blower frame of the blower are designed to have a removable sliding structure so that the installation and service inspection of these frames can be easily performed. It is something that

An embodiment of the present invention will be described below based on the drawings.1.
1 is a side plate that constitutes the unit body 2 of the air conditioner;
A pair of guide rails 3 facing this inner wall are brought into contact with each other, and both front and rear ends of the rails are screwed into the front flange pieces 4, 4 and the rear flange pieces 5.5 of the side plates 1, 1, respectively, with screws 6, 7. The side is covered.

8 is a rectangular support frame on which the sirocco type blower 9 and electric motor 10 are suspended, and has a discharge port 8a of the blower 9 in the center and blind portions 8b on both sides; 11 is a rectangular support frame for directing cold air and warm air blown from the blower 9 in the vertical direction; It is a box-shaped blow-off frame that has three vertical wind direction changing plates 12 that can be changed and six left and right wind direction changing plates 13 that can also be changed left and right. It is set to be smaller than the inner width dimension between the guide rails 3 and larger than the separation dimension between the pair of guide rails 3.

Reference numeral 14 denotes a U-shaped frame screwed onto the front edge 15 of the support frame 8 with screws 16, and a sealing material 17 such as foamed urethane is fitted into the frame so as to be tightly attached to the lower rear edge 18 of the blowing frame 11. The sealing prevents air from leaking from the plenum chamber 19 on the positive pressure side to the heat exchanger chamber 20 on the negative pressure side. A heat insulating material 24 such as glass wool is attached to the inner wall of the top plate 23 at the gap 22
The front end surface 25 of the front end face 25 of the front end face 25 is crimped and held.

26 is a back plate formed integrally with the top plate 23 and has a heat insulating material 27 affixed to the inner wall; 28 is a vertical bar grill attached to the front of the blow-out frame 11; and 29 is a front panel having a heat insulating material 30 affixed to the inner wall. It is.

The structure is as described above, and the support frame 8 is first inserted from the front through the notch 31 of the front flange piece 4 into the structure of the unit main body 2 in which the top plate 23 and the back plate 26 are assembled to the side plates 1 and 1. After placing it across a pair of guide rails 3,
The rear edge 3 of the support frame 8 is slidably guided backward on this rail.
When the U-shaped frame 14 is screwed onto the guide rail 3 with the screws 33, the support frame 8 is placed on the rail.
The blower 9 and the electric motor 10 are suspended and fixed via.

After that, the blow-off frame 11 is similarly inserted from the front, placed on the guide rail 3, and pushed in while sliding on the rail, and with the screw 6 escaped through the notched holes 34, 34, the hole 35 is inserted.
．． When holes 36 and 36 are screwed together with screws 37 and holes 38 and 39 are screwed together with screws 40, the sealing material 17 is compressed at the lower rear edge 18 of the blow-off frame 11, and the gap portion 22 of the upper rear edge 21 is screwed.
Then, the heat insulating material 24 is attached with the front end surface 25 thereof being crimped and held.

Then, the front panel 29 is attached with the heat insulating material 30 biting into the lower edge 41 of the blow-off frame 11 to form an air seal.
When the vertical bar grill 28 is attached, the assembly work is completed.

In this way, the air conditioner of this invention shares a guide rail that slides and guides the support frame of the blower, and also slides and guides the relatively heavy blow-off frame inside the wind direction change plate on this rail. Not only the support frame but also the blow-off frame can be easily installed and serviced and inspected, and the support frame and blow-off frame can be separated and removed to perform the work individually.

In addition, when the support frame and the blowout frame are assembled, the sealing material is placed in close contact across the entire width between the two frames, which prevents the blowout air from leaking from the plenum chamber to the heat exchanger room. Since a gap is formed at the upper rear edge of the blower frame, the strength of the blow-out frame is improved, and since the heat insulating material affixed to the inner wall of the top plate is crimped and held at this gap, peeling of the heat insulating material can be prevented. In addition, since the front end surface of the heat insulating material is covered by the difference, it is not visible from the front and looks good, which is extremely useful.
