Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a damper mounting structure in an integrated air conditioner.

(Prior Art) An example of an integrated air conditioner is shown in FIG.

The inside of the main body 1 of the air conditioner is partitioned by a partition plate 2 into an indoor side chamber 3 and an outdoor side chamber 4. An indoor heat exchanger 5, an indoor blower 6 and the like are arranged inside the indoor side chamber 3, and an outdoor heat exchanger 7, an outdoor blower 8 and the like are arranged inside the outdoor side chamber 4. Further, a compressor 10, a control box 11 and the like are arranged inside a machine room 9 formed in the lower part of the indoor side room 3.

A ventilation hole 13 is formed in the partition plate 2, and the ventilation hole 13 is opened and closed by a damper 12.

During the cooling operation of the air conditioner, the ventilation hole 13 is closed by the damper 12. Then, the indoor air is sucked into the indoor side chamber 3 through the intake port 31, cooled in the process of passing through the indoor heat exchanger 5, and then urged by the indoor blower 6, and thereafter,
It is blown out indoors through the air outlet 32. At the same time, the outside air is sucked into the outdoor chamber 4 through the intake port 33, and the temperature rises in the process of passing through the outdoor heat exchanger 7, and is then urged by the outdoor fan 8. It is discharged outdoors.

During the exhaust operation, the ventilation hole 13 is opened by the damper 12, and the indoor blower 6 is driven. Thus, the indoor air is sucked into the indoor-side chamber 3 through the intake port 31 and simply flows through the indoor heat exchanger 5 without exchanging heat with the indoor heat exchanger 5, and then is urged by the indoor blower 6 to pass through the ventilation hole 13. After entering the outdoor chamber 4, it is discharged to the outside through the exhaust port 34.

The conventional mounting structure of the damper 12 is shown in FIGS. 3 to 6.

The partition plate 2 is provided with a slit 14 and ventilation holes 13 on the left and right sides of the slit 14, and an insect net 16 is stretched in each ventilation hole 13.

As shown in FIG. 5, the damper 12 includes a central inclined portion 12a and lid portions 12b and 12c extending from both ends thereof and extending in parallel with each other.
The inclined portion 12a penetrates the slit 14, and the lid portion 12b,
Wind shields 15 are attached to the surfaces of the 12c facing the ventilation holes 13, respectively.

As shown in FIG. 6, one side edge of the inclined portion 12a of the damper 12 is provided with a notch 18 formed at the tip of one shaft 17 as shown in FIG.
The damper 12 is locked to the shaft 17 by engaging the claw 20 provided at the tip of the protrusion 19 protruding from the tip of the shaft 17 with the locking hole 21 formed in the inclined portion 12a. It

Similarly, the other side edge of the inclined portion 12a is fitted into the notch 23 formed at the tip of the other shaft 22 and the shaft
The damper 12 is locked to the shaft 22 by engaging the claw 25 provided at the tip of the protrusion 24 protruding from the tip of the 22 with the locking hole 26 formed in the inclined portion 12a.

Then, the rear end portion of the shaft 17 is rotatably inserted into the through hole 27 formed in the rib 2a standing on one side of the partition plate 2, and the rear end portion of the shaft 22 is attached to the partition plate 2. A rib (2b) erected on the other side is rotatably inserted into a through hole (28) formed in the rib (2b).
Thus, the damper 12 is rotatably supported by the partition plate 2 around the shafts 17 and 22, and is rotated by the motor 29 connected to the rear end of the shaft 22.

(Problems to be Solved by the Invention) In the above-described conventional mounting structure, when mounting the damper 12, first, the motor 29 is connected to the shaft 22 and then the tip of the shaft 22 is inserted into the through hole 28. Next, damper 12
The slanted portion 12a is fitted in the slit 14, the other side edge is fitted in the notch 23, and the claw 25 is engaged with the locking hole 26. Next, the tip of the shaft 17 is inserted into the through hole 27, the notch 18 at the tip is fitted into one side edge of the inclined portion 12a, and the claw 20 is engaged with the locking hole 21.

Therefore, there is a problem that it is difficult to align the cut 18 with one side edge of the inclined portion 12a in a state where the shaft 17 is inserted into the through hole 27, and it takes time to attach the damper 12.

(Means for Solving the Problems) The present invention has been proposed to solve the above problems, and its gist is to provide a partition plate for partitioning the inside of the main body into an indoor side chamber and an outdoor side chamber. A damper for opening and closing the drilled ventilation hole, one shaft having a notch formed on the tip of one side edge of the damper, and a notch inserted on the other side edge of the damper for the tip. In a damper mounting structure in an air conditioner that is formed and has the other shaft to which a drive source is connected at the rear end, a state in which the notch of the tip of the one shaft is inserted into one side edge of the damper. The rear part of one of the shafts is detachably fitted, and a clamp for rotatably supporting the one shaft in this state is fixed to the partition plate. It is in.

(Operation) Since the present invention has the above-mentioned configuration, the rear portion of one shaft is fitted to the clamp in a state where the notch of the shaft is inserted into the other side edge of the damper.

(Embodiment) One embodiment of the present invention is shown in FIGS. 1 and 2.

A clamp 31 made of an elastic material is fixed to the inner bottom of the recess 30 formed in the partition plate 2. The clamp 31 has a circular cross section with one part cut away, and the rear part of the shaft 17 is rotatably supported by the clamp 31 by fitting the rear part of the shaft 17 into the clamp 31 through the notch 31a.

Other configurations are similar to those of the conventional one shown in FIGS. 3 to 6, and corresponding members are designated by the same reference numerals.

Then, when mounting the damper 12, after connecting the drive source 29 such as a motor to the other shaft 22, the shaft 22
The motor 29 is fixed to the partition plate 2 by inserting the tip of the above into the through hole 28. Next, the inclined portion 12a of the damper 12 is slit 14
Then, the other side edge of the inclined portion 12a is fitted into the notch 23 of the shaft 22, and the claw 25 is locked in the locking hole 26.

Thereafter, the notch 18 of the shaft 17 is fitted into one side edge of the inclined portion 12a, and the claw 20 is engaged in the locking hole 21 to attach the shaft 17 to the damper 12.

After that, the rear part of the shaft 17 is cut into the clamp 31.
Insert from a and fit into the clamp 31.

After attaching the shaft 17 to the damper 12,
The other side edge may be inserted into the notch 23 of the shaft 22.

Then, after attaching the shaft 17 to the damper 12, it is sufficient to fit the rear part of the shaft 17 to the clamp 31, so that the shaft 17 at the tip of the shaft 17 is inserted in the through hole 27 as in the conventional case. The difficult work of aligning the notch 18 with one side edge of the damper 12 is unnecessary.

(Effect of the Invention) According to the present invention, the rear portion of one of the shafts is detachably fitted in a state where the notch at the tip of the shaft is inserted into one side edge of the damper. Since the clamp that rotatably supports the is fixed to the partition plate, the cutout of one shaft is inserted into the other side edge of the damper, and the damper is partitioned by fitting the rear part of this shaft to the clamp. It is rotatably supported by the plate.

As a result, the work of attaching one of the shafts to the damper becomes easy, and the other shaft of the shaft can be easily fitted to the clamp, so that the work of mounting the damper becomes easy and the installation time can be shortened.
