Description

[Detailed Description of the Invention] The present invention relates to a wind direction changing device for an air conditioner or the like.

Conventional air direction changing devices such as air conditioners connect one end of a connecting rod to the driving device, which transmits the rotational motion of the driving device by an electric motor and a crank lever as reciprocating motion, while the other end is connected to the inside of the interlocking wind direction plate. By arbitrarily selecting and connecting multiple connecting holes provided in one of the adjusting plates, an appropriate wind direction can be obtained depending on the situation and purpose of the room in which the equipment is placed. However, according to this structure, when connecting the connecting rod and the connecting hole of the adjustment plate, it is necessary to remove the front cover of the device and then insert your finger between the wind direction plates, which makes the operation difficult. It was extremely troublesome.

The present invention was devised in view of the above points, and is designed to obtain an appropriate wind direction according to the situation and purpose of the room in which the equipment is placed by an extremely simple operation.

An embodiment of the present invention shown in the figure below will be described. 1 is a board 2, which is provided oppositely above and below a cold air outlet of an air conditioner, etc.;
A rotary shaft 3 protruding from the upper and lower ends of the board 2 is rotatably supported, and a plurality of wind direction boards are arranged in parallel at equal intervals between the boards 2 and 2. is provided with an interlocking plate 4 that connects the same wind direction plate 1 in order to change the rotation at the same time.

Reference numeral 5 denotes a connecting hole provided in one of the wind direction plates 1, and is formed in a flat connecting portion 6, as shown in FIG. 1, for example.

Reference numeral 7 denotes a motor cover having a recess 8 for accommodating an electric motor, which will be described later. While being rotatably supported, a movable rod 10 having a connecting shaft 11 fixed to its tip is attached to its lower end.

Reference numeral 12 denotes a low-speed electric motor housed in the recess 8 of the motor cover 7, and its shaft 13 passes through an elongated hole 14 formed in the lower substrate 2 substantially concentrically with respect to the rotating shaft 3 of the wind direction plate 1. One end of a crank lever 15 which rotates about the same shaft 13 is fixed to the tip of the crank lever 15, and a connecting shaft 16 is fixed to the other end of the crank lever 15.

Reference numeral 17 denotes a connecting rod that transmits the rotational motion of the crank lever 15 to the wind direction plate 1 as a reciprocating motion, one end of which is connected to the connecting shaft 16 of the crank lever 15, and the other end connected to the connecting hole 15. .

18 is pivoted at its intermediate portion 19 and is rotatable around the same portion, and one end is connected to the connecting shaft 11 of the movable rod 10.
It is an abbreviated operating lever with the other end protruding from the front of the device and a knob 20 attached to the tip.By operating the operating lever 18, the electric motor 12 is moved and the wind direction angle of the wind direction plate 1 is changed. I'm trying to get it.

When the electric motor 12 is driven in the above configuration, the crank lever 15 performs a rotational movement due to the rotation of the shaft 13.

This rotational motion is transmitted to the connecting rod 17 and converted into a reciprocating motion by the connecting rod 17, and this reciprocating motion is further transmitted to the wind direction plate 1 and automatically rotates the wind direction plate 1 in the same direction and by the same angle. move and move the cold air flow.

Here, when the operating lever 18 is set at the center and the shaft 13 of the electric motor 12 is positioned approximately at the center of the elongated hole 14 as shown in FIG. It rotates and blows cold air evenly.

Next, as shown in FIG. 3, when the operating lever 18 is moved to the left to position the shaft 13 of the electric motor 12 in the front part of the elongated hole 14, the wind direction plate 1 is moved mainly left and right from the center to the left and right a-1. ), it automatically rotates within the range of 1 and blows cold air mainly to the left area.

Furthermore, as shown in FIG. 4, when the operating lever 18 is moved to the right to position the shaft 13 of the electric motor 12 at the rear part of the elongated hole 14, the wind direction plate 1 is moved mainly to the right of the center from left to right a-b. It automatically rotates within the range and mainly blows cold air to the right area.

In the above embodiment, three different wind direction states have been described, but by operating the operating lever 18, it is possible to obtain a wind direction angle depending on the situation and purpose of the room in which the equipment is placed.

Further, in the above embodiment, the elongated hole 14 is formed substantially concentrically with respect to the rotation axis 13 of the wind direction plate 1, but it may be formed so as to extend left and right.

Further, in the above embodiment, the electric motor 12 is moved by the operating lever 18 via the moving rod 10, but it is also possible to attach one end of the direct operating lever 18 to the electric motor 12 and operate it directly. .

As described above, in this invention, the position of the electric motor is moved using the operating lever to change the wind direction angle of the wind direction plate, so it is possible to obtain the wind direction according to the situation and purpose of the room in which the equipment is placed. Moreover, since the operation can be performed from outside the device, it is extremely easy to operate.
