Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to an indoor unit of an air conditioner.
More specifically, the present invention relates to a drive means for a wind direction adjustment plate that uses a motor to change the inclination of the wind direction adjustment plate.

[Technical background of the invention]

In recent years, development of home automation has progressed, and as part of this effort, indoor units of air conditioners are equipped with motors that drive wind direction control plates, and the wind direction is controlled by remote control.

By the way, this type of indoor unit generally has a wall-mounted housing body that has a heat exchanger, a blower fan, etc., an indoor air intake opening and an air blowout opening, and is detachably placed on the housing body. A front panel is provided with a rotatable wind direction adjustment plate disposed within the air blowing opening.However, when a motor is provided and the wind direction adjustment plate is remotely controlled, conventionally both the motor and the wind direction adjustment plate are mounted in a housing. It is installed on the main body side. Therefore, when changing the design of the front panel, etc., the front panel is always constrained by its relationship with the wind direction adjusting plate provided on the housing body, and there is a problem in that the design cannot be changed freely.

[Purpose of invention]

This idea was devised in view of the above-mentioned conventional problems, and its purpose was to provide a motor on the housing body side, attach a wind direction control plate on the front panel side, and to attach the front panel to the housing body. An object of the present invention is to provide an indoor unit of an air conditioner in which a wind direction adjusting plate and a motor are connected.

〔Example〕

Hereinafter, this invention will be described in detail with reference to embodiments shown in the accompanying drawings.

As shown in FIG. 1, this indoor unit includes a wall-mounted housing body 1 that is formed to be attached to a wall in a room, and a front panel that is detachably placed on the front part of the housing body 1. 2. An air passage including a heat exchanger, a blower fan, etc. (not shown) is formed in the housing body 1, and an electrical component box 4 is arranged on the side thereof with a partition plate 3 interposed therebetween.
According to this embodiment, a geared mode 5 is provided at the bottom of the electrical equipment box 4. On the other hand, the front panel 2 is formed with a suction opening 6 for indoor air and an air blowing opening 7. In this case,
A wind direction adjusting plate 8 is rotatably attached to the air blowing opening 7. That is, as shown in FIG. 2, the side wall 9 of the front panel 2 forming the air blowing opening 7 is provided with a shaft insertion hole 11 through which the rotation shaft 10 of the wind direction adjustment plate 8 is inserted and held. ing. In this invention, the shaft insertion hole 11
A driven gear 1 that meshes with the drive gear 5 of the geared motor 5a is attached to the end of the rotating shaft 10 inserted through the
2 is installed.

Therefore, as shown in FIG. 3, when assembling the front panel 2 to the housing body 1, the driven gear 12 provided on the wind direction adjustment plate 8 side and the drive gear 5a of the geared motor 5 are meshed. Then, the geared motor 5 can set the wind direction adjustment plate 8 at a predetermined angle.

Another embodiment of the invention is shown in FIGS. 4 and 5. That is, as described above, the driven gear 12 and the driving gear 5a engage and disengage as the front panel 2 is attached and detached, but in the embodiment shown in FIG. A gear guide means 13 is provided. This gear guide means 13 is made of a metal fitting formed to be screwed onto a boss 16 protruding from the inner wall surface of the front panel 2, for example. A guide groove 13a is provided for guiding the drive gear 5a to a position where it meshes with the driven gear 12. Further, the gear guide means 13 is provided with a bearing hole 13b for pivotally supporting the rotating shaft 12a of the driven gear 12. Therefore, in this embodiment, when the front panel 2 is attached to the housing main body 1, the driven gear 12 and the driving gear 5a are surely engaged through the gear guide means 13.

On the other hand, in the embodiment shown in FIG. 5, the geared motor 5 is provided with a holding member 15 made of, for example, synthetic resin, and the geared motor 5 is swung to the lower part of the electrical component box 4 via this holding member 15. The coil spring 17 biases it toward the front panel 2 side. That is, the holding member 15 is provided with a cylindrical boss 16 having a bearing hole 16a, and after aligning the bearing hole 16a with the bearing holes 4a, 4a formed in the electrical component box 4, The geared motor 5 is pivotally supported by the electrical component box 4 by inserting the pin 18 into the bearing holes 4a, 16a. Further, the coil spring 17 is fitted into the boss 16, and one end 17a thereof is locked to the electrical component box 4 side, and the other end 17b is locked to the holding member side.

Therefore, according to this embodiment, even if there is some dimensional error when assembling the front panel 2 to the housing body 1, the drive gear 5a and the driven gear 12
will allow this and ensure a secure meshing.

〔effect〕

As described above, according to this invention, the geared motor 5 is arranged on the housing main body 1 side, the wind direction adjusting plate 8 is rotatably provided on the front panel 2 side, and the driven gear 12 is attached to the rotating shaft 10, and the driven gear 12 is attached to the front panel 2 side. When assembling the panel 2 to the housing body 1, the driven gear 12 is connected to the drive gear 5a of the geared motor 5.
By meshing with the front panel 2, the design of the front panel 2 can be changed without being too constrained by the structure of the housing body 1 as in the past, resulting in a greater degree of freedom in design. be done.
