Problems solved by technology

[0006] Here, if the operator mistakenly inserts into the abutting part, it may be assembled in an incompletely inserted state.
In general, it has been difficult to confirm the abutment condition, etc., and it has become an important factor in the deterioration of the deviation in the direction of the rotation axis that occurs during the assembly of the wind direction blade.

Embodiment approach 1

[0023] Hereinafter, an indoor unit and the like according to an embodiment of the present invention will be described with reference to the drawings and the like. In the following drawings, elements attached with the same reference numerals are the same or corresponding elements, and are common throughout the entirety of the embodiments described below. In addition, the form of the component shown in the whole specification is an illustration only, and is not limited to the form described in a specification. In particular, the combination of components is not limited to the combinations in the respective embodiments, and components described in other embodiments can be applied to different embodiments. In addition, in the figure, the upper side is referred to as "upper side" and the lower side is described as "lower side". In addition, when there is no need to distinguish or identify a plurality of devices of the same type that are distinguished by subscripts, etc., subscript...

Embodiment approach 2

[0038] Although not specifically shown in the above embodiment, for example, the wind direction vane 4 and the vane gear 10 may be formed in different colors, and at least the claws of the blade claws 4b may be marked with a color different from that around the fitting hole 10a. , it is easier to visually recognize that the claw is fitted into the fitting hole portion 10a and that the wind direction vane 4 is inserted until it abuts against the bearing hole 10b of the vane gear 10 .

Embodiment approach 3

[0040] In the above-mentioned embodiment, although the claw formed on the blade claw portion 4b of the wind direction blade 4 is fitted into the fitting hole portion 10a formed in the blade gear 10, the present invention is not limited thereto, as long as it can at least It is only necessary to visually recognize that the wind direction vane 4 is inserted until it contacts the bearing hole 10 b of the vane gear 10 . For example, instead of the blade claw portion 4b, a mark (logo) is attached to the wind direction blade 4 in advance in color, shape, or the like. The fitting hole of the fitting hole portion 10a may be used as a hole for confirmation, and when the wind direction vane 4 is inserted into contact, the mark can be observed from the hole for confirmation.

Abstract

An indoor unit 1 includes: an airflow direction louver 4 that rotates about a vane shaft 4a and changes a direction of air that is blowing from an air outlet 3b; and a louver gear 10 that transmits a force from a vane drive motor part 9 to the airflow direction louver 4. The airflow direction louver 4 has an insertion indicator such as a nail. The louver gear 10 has a fitting hole 10a that allows the insertion indicator to become visible when the airflow direction louver 4 is inserted into a bearing hole 10b of the louver gear 10 and reaches the bottom of a bearing hole 10b.

Description

technical field [0001] The present invention relates to indoor units such as air conditioners, for example. In particular, it relates to attachment of wind direction vanes (wind direction deflectors) arranged at discharge ports, and the like. Background technique [0002] For example, in indoor units such as air conditioners, wind direction vanes that change the wind direction of air discharged from the discharge port are often provided at the air discharge port as wind direction deflectors. The wind direction blade has a planar portion that guides the air discharged from the discharge port. In addition, both ends of the main body of the indoor unit have rotation shafts for providing flat surfaces. On the other hand, a hole for rotatably supporting the inserted rotating shaft is formed on the main body side. A bearing portion on which a drive motor is disposed is provided on one hole side. In addition, the drive motor can rotate the rotating shaft (air direction vane) fr...
