Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a damper device for an air conditioner equipped with a damper that adjusts the amount of circulating air.

[Conventional technology]

Conventionally, damper devices for this type of air conditioner were manufactured by Jikosho.
No. 56-13555 and is constructed as shown in FIGS. 6 and 7. To explain this based on the figure, 1 is the air conditioner main body, 2 is a cooler provided on the indoor side of the air conditioner main body 1,
3 is a casing provided at the rear of this cooler 2; 4 is a motor 5 provided within this casing 3;
an indoor fan connected to a rotating shaft 6; 7 is a partition plate that defines an indoor side and an outdoor side of the air conditioner main body 1 and forms an indoor air passage together with the casing 3; 8 is this partition plate; 7 is an intake hole for sucking air into the indoor air passage; 9 is an outdoor fan provided on the outdoor side of the air conditioner body 1 and connected to the rotating shaft 6; 10 is the rear of the outdoor fan 9; 11 and 12 are bell mouths and fan covers that form an outdoor air passage; 13 is a cable that is swingably provided around the opening of the intake hole 8 and partially fixed with screws; 14 is an intake damper that opens and closes by advancing and retreating from the intake hole 8.
A fixing metal fitting having an L-shaped cross section is welded to a nearby partition plate 7, 15 is a cable fixing plate fixed to this fixing metal fitting 14 with screws and has a notch 16 at the upper end, and 17 is a cable fixing plate of this fixing plate 15. The wires 17a held in the notches 16 are connected to the intake damper 1, respectively.
This cable is connected to the damper wire 18 and lever 19 of No. 3. Further, 20 and 21 are a compressor and a base plate, respectively.

In the damper device of the air conditioner configured in this way, when the lever 19 is rotated, the intake damper 13 opens and closes as the cable 17 moves forward and backward. At this time, the opening degree of the intake hole 8 changes to adjust the amount of intake air.

In the air conditioner, the refrigerant is raised to high temperature and pressure by the compressor 20, and then cooled and liquefied by the outdoor fan 9 when passing through the condenser 10. Then, when passing through the cooler 2, heat is removed from the air taken in by the indoor fan 4 and the air is vaporized. At this time, the intake air is cooled, passes through the casing 3, and is blown into the room from the outlet of the air conditioner main body 1.

[Problem that the invention attempts to solve]

However, in the conventional damper device of an air conditioner, it is necessary to separately prepare the damper wire 18 as a cable wire connection part, which not only increases the number of parts but also makes the installation work complicated. Ta. In addition, since the intake damper 13 is swingably provided around the opening of the intake hole 8 by means of a hinge, and a portion thereof is fixed, the air may be introduced into a place that is far away from the intake damper 13, such as a duct, etc. When it is necessary to guide air with
It was extremely difficult to connect the intake damper 13 to the duct.

The present invention was devised in view of the above circumstances, and it is an object of the present invention to provide a damper device for an air conditioner that has a simplified structure and allows easy connection of the damper to the duct.

[Means for solving problems]

The damper device for an air conditioner according to the present invention includes a duct having a slit that opens to the side and is connected to an air distribution port of the air conditioner main body, and an opening/closing device inserted into the duct through the slit to open and close the air distribution port. and a damper for air conditioning having a pivot part rotatably supported on the part and the duct and integrally provided with a cable wire connection part.

[Effect]

In the present invention, since the cable wire connection portion is integrally provided with the damper, the number of parts can be reduced accordingly, and the installation work can be omitted. In addition, the duct has a slit that opens laterally, and the damper has an opening/closing part that is inserted into the duct through the slit to open and close the air flow opening, and a pivot part that is rotatably supported on the duct. It can be connected by insertion through the slit.

FIG. In the figure, what is indicated by the reference numeral 31 is the main body of the air conditioner, and an indoor unit 33 and an outdoor unit 3 placed on a base 32 at a predetermined interval.
4, and is fixed to a wall (not shown) by inserting a portion through an opening. The cabinet 35 of the indoor unit 33 is equipped with a front panel 38 having an inlet 36 and an outlet 37 at its front opening, and a casing 39 forming an air passage inside.
is provided. A cooler 40 for cooling indoor air and a blower fan 41 driven by a motor (not shown) are disposed inside the casing 39, and a blowing nozzle 42 is provided in front of the blower fan 41. . On the other hand, a blower fan, a condenser, a compressor, etc. (not shown) are installed in the outdoor unit 34, and the condenser, compressor, and the cooler 40 are connected to each other by refrigerant piping (not shown). It is connected. The cabinet 35 and the casing 39 are provided with an air circulation port 35a and an intake hole 39a, respectively.
A damper device 43 is disposed between the two. This damper device 43 includes a duct 46 that is fixed to the cabinet 35 with screws 44 and has a cylindrical duct body 45 connected to the air flow opening 35a and the intake hole 39a, and a cable 47 for opening and closing the damper.
A damper 48 for adjusting the amount of air is provided, which opens and closes the air flow opening 35a by moving forward and backward. The duct main body 45 is formed in a curved shape so that the opening end on the intake side matches the shape of the blowout nozzle 42,
A shaft groove 50 having a slit 49 opening laterally is provided on the side, and a cable support portion 54 having a square hole 52 for attaching a fixture 51 and an attachment boss 53 is extended.
