Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a wind direction changing device installed inside a discharge port of an air conditioner (hereinafter referred to as an air conditioner).

Conventional configuration and problems thereof Conventionally, the one shown in FIG. 1 has been a common wind direction changing device for a ceiling-suspended air conditioner. That is, in this figure, a is the axis (hereinafter referred to as the axis) of the wind direction changing device installed inside the air conditioner outlet, and the wind direction plate b is integrally molded with plastic and is provided at an appropriate interval and angle to the axis. one end is inserted into a bearing d fixed to the side plate c of the air conditioner main body, and the remaining end is connected to the electric motor e fixed to the side plate c′,
The wind direction is changed by rotating the shaft a by the rotation of the electric motor e. However, if the shaft a and the wind direction plate b are integrally molded, if the longitudinal direction of the shaft a becomes longer due to the expansion of the air conditioner model range, the mold cost will become heavier.
This increases manufacturing costs, and the above-mentioned drawbacks due to manufacturing each model are unavoidable.

Purpose of the invention The object of the present invention is to eliminate the above-mentioned drawbacks and provide a wind direction changing device that does not require molding costs even if the longitudinal direction becomes longer due to the expansion of the model range of air conditioners.

Structure of the invention In order to achieve this purpose, the shafts that make up the wind direction changing device are divided and connected by connecting pipes, and wind direction plates are provided on each shaft at both ends, and the length of the connecting pipe as the central shaft is This was created by changing the overall dimensions of the air conditioner, and by using only the connecting pipe for each model of air conditioner, it was possible to reduce costs.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes the main body of the air conditioner. A heat exchanger 8, a wind direction changing device 9, a wind direction changing plate 10 for changing the upper and lower wind directions, and a discharge grille 1 attached to the
1 and a discharge port 13. Further, the wind direction changing device 9 is divided into shafts 14a and 14b as shown in FIG. 4, and each has a wind direction changing plate 15 provided at an appropriate interval and angle. Connected with connecting pipe 16, each with screw 1
It is fixed at 7. One end of the thus integrated shaft is inserted into a bearing 18 fixed to one side plate 6, and the other end is inserted and connected to the rotating shaft of an electric motor 19 fixed to the other side plate 7. Therefore, in conjunction with the rotational movement of the electric motor 19, the wind direction changing plate 15
rotates to change the wind direction from side to side.

Further, as shown in FIGS. 4 and 5, the connecting pipe 16 has screws 17 inserted into the shafts 14a and 14b.
A large number of screw holes 20 for fixing the shafts 14a, 14b are inserted into the connecting pipe 16 without any limitation. That is, the axis 14
The screws 17 are used to fix the shafts 14a, 14b and the connecting pipe 16 not only in the screw holes 20 at both ends as shown in FIG. screw hole 20
It may be fixed at the position.

This is a shaft 14a on which the wind direction changing plate 15 is integrally molded.
Alternatively, all 14b can be mass-produced with a certain length using a predetermined mold, and the length between the two side plates 6, 6 can be adjusted for different models of air conditioners with different lengths in the longitudinal direction of the discharge port 13. It is possible to deal with cases of different sizes by simply changing the insertion distance of each shaft 14a, 14b into the connecting pipe 16. Although there is no wind direction changing plate in the center of the outlet 13 where the connecting pipe 16 is present, the wind direction changing plates 15 located on both sides can sufficiently cover changes in the left and right direction.

Effects of the Invention As is clear from the above explanation, according to the present invention, the air direction changing device that configures models with different longitudinal lengths of the discharge ports is not formed in a series, but is divided into connecting pipes. It has a structure that connects with
The complex molded product, which has wind direction plates on both ends, is the same and can be shared, which reduces mold costs and allows smooth expansion of the model range without increasing manufacturing costs.
