Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a heat exchange unit equipped with a heat exchanger, a blower, etc., and a device for attaching lead wires extending from the blower. .

(b) Prior Art Conventionally, an example of the structure of this type of heat exchange unit has been disclosed in JP-A-60-38570.

According to this content, the lead wire of the blower extends from the rear side of the blower and is guided to the upper end along the bent piece at the rear edge of the support base of the blower. After that, this lead wire is connected to the opening (ventilation hole) at the top of the support base.
It extends laterally from the opening, is fixed with a clamper near this opening, and is guided into a machine room where electrical components are housed.

(c) Problems to be solved by the invention In such a heat exchange unit, the lead wire is led along the bent piece of the support base to the upper end, and then extends laterally. . For this reason, there was a drawback that the length of the lead wire was relatively long. Also, although this lead wire is fixed with a clamper at the upper end of the mounting base, it does not follow the bending piece near this fixed part, so if the clamper becomes loosely fixed, the lead wire will droop and get caught in the blower. There were some drawbacks.

The object of the present invention is to shorten the length of the lead wire connecting the blower to the electrical components in the machine room, and to securely fix the lead wire.

(d) Means for solving the problem In order to achieve this objective, the present invention provides a bent piece on the edge of the support base of the blower, and also provides a notch in a part of this bent piece. The lead wire of the blower is guided from the inside of the bent piece to the outside through the notch, and a fixing member for the lead wire is engaged with the notch.

(E) Function By extending the lead wire from the notch in the bent piece of the support base, the lead wire is connected straight from this notch to the electrical components in the machine room.

(f) Example In Fig. 2, 1 is an outdoor heat exchange unit of a separate air conditioner, 2 is a bottom plate, and 3 is attached along the left edge 4, rear edge 5, and right edge 6 of this bottom plate. The approximately U-shaped exterior panel has an inlet 9 on the left side 7 and rear side 8, and a power supply service port 11 on the right side 10.
and a notch 12 are provided. This notch 12 has a mounting piece 13 fixed to the right edge 6 of the bottom plate 2.
is located, and a valve (not shown) is fixed to this mounting piece. A partition plate 14 divides the inside of the unit 1 into a heat exchange chamber 15 on the left side and a machine room 16 on the right side. This partition plate 14 has two beads 17 running in the horizontal direction, and this partition plate 14
is increasing its strength. 18 is a compressor, and 20, which is placed on the bottom surface 19 of the bottom plate 2 on the side of the machine room 16, is an electrical equipment board that is placed above the compressor 18, and the left rising piece 21 of this board is tilted diagonally backward. , the right side rising piece 22 is inclined diagonally upward. Reference numeral 25 denotes a heat dissipating member, with a heat dissipating fin 26 cut and raised on the left side, and a power transistor module 27 fixed on the right side. The heat radiation member 25 is attached to the opening 28 of the left rising piece 21 of the electrical equipment board 20, and the power transistor module 27 is located on the right side of this rising piece 21, and the heat radiation fin 26 is located on the left side. Further, a terminal board (not shown) is attached to the right rising piece 22 of the electrical equipment board 20 so as to face the service port 11 of the exterior panel 3. A capacitor 29 is erected at the rear of the electrical equipment board 20 and fixed by a rear rising piece 30 of the electrical equipment board 20 and a band 31. Reference numeral 32 denotes an auxiliary plate that is removably erected in front of the electrical equipment board 20, and electrical equipment boards (printed circuit boards) 33, 34 are attached to both the front and rear surfaces of this board. In this way, capacitor 2
The electrical equipment board 20 to which the electrical equipment boards 9 and electrical equipment boards 33 and 34 are attached is fixed to the partition plate 14 in the following manner. That is, the bent portion 23 of the left rising piece 21 of the electrical equipment board 20 is connected to the engaging piece 2 of the partition plate 14.
4, and the hole 80 of the bent portion 23 and the hole 81 of the engaging piece 24 are screwed together. When the electrical equipment board 20 is fixed to the partition plate 14 in this manner, the heat radiation fins 26 face the heat exchange chamber 15 through the opening 82 of the partition plate 14. 35 is a reactor, and 36 is a cover of this reactor, which is attached to a notch 37 below the partition plate 14.

38 is a plate fin type heat exchanger bent into a substantially L shape, and is placed on the heat exchange chamber 15 side.
When the heat exchanger is mounted in this way, this heat exchanger 38 is aligned with the inlet 9 of the exterior panel 3. 39 is a blower placed in front of this heat exchanger 38;
A motor 40 of this blower 39 is fixed to a support base 41. The lower end 42 of this support stand 41 is fixed to approximately the center 43 of the bottom plate 2 on the heat exchange chamber 15 side. or,
The upper end 44 is engaged with the upper edge 45 of the plate-fin heat exchanger 38 and fixed to the upper edge 46 of the exterior panel 3. A front panel 47 constitutes the front and top surfaces of the heat exchange unit 1, and a nozzle plate 49 is provided on the front surface 48 of this panel. 5
0 is a protective guard that covers this nozzle plate 49.

FIG. 1 shows the main parts of the support stand 41 of the motor 40, and 51 is a bent piece formed at the edge of the support stand, which is bent toward the heat exchanger 38 side. 5
2 is a ventilation hole, and a heat exchanger 38 is also installed on the edge of this ventilation hole.
A bent piece 53 facing the side is provided. In this way, the bending pieces 51 and 53 are provided on the support base 41 to increase the strength of the support base 41. 54
is a notch provided in the bent piece 51 on the right edge of the support base 41. 55 is a lead wire extending from the motor 40;
It is inserted through the mounting hole 56 of , and then guided upward along the inside of the bent piece 51 on the right edge.
This lead wire 55 is led out from the notch 54 and extends to the right in FIG. 57 is a clamper (fixing member) for fixing the lead wire 55 to the support base 41, and is wound together with the lead wire 55 around the right leg piece 58 of the mounting base 41 using the notch 54 for positioning. When the clamper 57 is wound around the right leg piece 58 in this manner, there is no fear that the clamper 57 will be caught in the notch 54 and moved downward.

(g) Effects of the invention As described above, the present invention provides a bent piece on the edge of the support base of the blower, runs the lead wire of the blower along this bent piece, and connects the lead wire with the cut piece of the bent piece. Since the lead wire is guided to the outside of this piece from the notch and the position of the fixing member for this lead wire is determined by this notch, the lead wire continues to follow the bent piece until it comes out of the support base, so that the lead wire is This can reduce the risk of it falling down or becoming loose and getting caught in the blower. Also, since this notch is led from the middle of the bent piece of the support base, it is possible to connect the lead wire straighter than this notch to the electrical components in the machine room of the heat exchange unit to shorten the lead wire. can.
