Description

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

[Conventional technology]

Figures 1 and 2 are perspective views showing a conventional wind direction changing device disclosed in, for example, Japanese Utility Model Publication No. 48-25793. Shafts 3, 3' protruding from the upper and lower ends of the substrates 2, 2' are rotatably supported, and a plurality of wind direction plates 4 are arranged in parallel at equal intervals between the substrates 2, 2'.
5 is an interlocking plate that connects the rear upper ends of the respective wind direction plates 1 in order to change the rotation of the wind direction plates 1 at the same time; As shown in the figure, for example, approximately radially (straight line) a, a', a'' centering on the axis 3 or the center line of the wind direction plate 1, and concentric circles b, b',
a perforated plate with a plurality of connecting holes perforated in each hole, 11 is a low-speed driving electric motor;
One end of a rotary lever 9 that rotates around the shaft 10 is fixed to the shaft 10, and a connecting shaft 8 is fixed to the other end of the rotary lever 9. 22 is a connecting rod that connects one end to the connecting shaft 8 of the rotary lever 9 and the other end to an arbitrary connecting hole 23 of the perforated plate 5, and converts rotational movement into reciprocating movement. In connection with the connection hole, moving on a concentric circle changes the wind direction, and moving radially on the concentric circle changes the air blowing angle in the same wind direction.

Next, to explain the operation, when the electric motor 11 is driven, the rotational force of the shaft is transmitted to the rotary lever 9, and the rotation of the rotary lever 9 causes the connecting shaft 8 to perform a circular motion around the shaft 8, and this circular motion causes the connection The rod 22 reciprocates and automatically rotates the wind direction plate 1 in the same direction and by the same angle, thereby moving the flow of cold air.

Therefore, as shown in FIG. 5, one end of the connecting rod 22 is connected to the connecting shaft 8 of the rotary lever 9, and the other end is connected to the connecting hole 23 at the matching point of a and b. It automatically rotates within the range a-b to move the flow of cold air.

In another conventional technique, referring to the perspective view shown in FIG. axis 1
Perform a circular motion with 0 as the center. Due to this circular movement, the interlocking rod 7 connected to the rotating lever 9 by the connecting shaft 8 performs a reciprocating movement, and is integrally attached to the wind direction plate 1.
Or it is transmitted to the wind direction plate 1 via an arm 5 formed separately. At this time, the wind direction plate 1 is supported by the substrates 2, 2' arranged in parallel at the upper and lower ends of the air outlet and the shafts 3, 3' of the wind direction plate 1, and is connected to the other wind direction plates by the interlocking plate 4. Also, reciprocating motion can be transmitted.

[Problem that the invention attempts to solve]

In a conventional wind direction changing device, one end of a connecting rod that transmits the rotational motion of a drive device by an electric motor and a rotary lever as reciprocating motion is connected to the drive device, and the other end is concentrically connected to a perforated plate provided on the wind direction plate. Two or more connecting holes are drilled on the radial line and connected as appropriate. In this connection, the direction of the air moving in concentric circles is changed, and the angle of the air blowing in the same direction moving on the radial line is changed. I can only do that. Another drawback is that the direction of the air cannot be changed depending on the situation of the room in which the air conditioner is installed and the usage requirements.

This idea was made in order to solve the above problems, and the air conditioner body can be relatively freely changed in the direction and angle of the air according to the situation and location of the room in which it is installed, as well as the requirements of the purpose. The purpose is to provide comfortable air conditioning.

[Means for solving problems]

The air conditioner wind direction changing device according to this invention is
A plurality of wind direction plates, a plate with a guide groove in which an arm with a pin molded on the wind direction plate is slidably connected and an eccentric cam can be inserted, a plate connected to a sliding plate, and a fulcrum shaft with teeth that mesh with regulation teeth. It has a movable fulcrum lever and an eccentric cam that is inserted into the guide groove of the sliding plate.

The air conditioner wind direction changing device based on this invention is
By providing an eccentric cam, the fulcrum lever can be arbitrarily displaced to freely change the wind direction.

[Example of idea]

Embodiments of the present invention shown in FIGS. 2 to 4 will be described below. When the electric motor 11 is driven, the eccentric cam 13 is rotatably attached as the electric motor shaft 10 rotates. Furthermore, the eccentric cam 13 is rotatably mounted in the guide groove 17 of the sliding plate 12. Further, a fulcrum lever 14 is connected to one end of the sliding plate 12 by a movable fulcrum 21. The fulcrum lever 14 is provided with a connecting fulcrum hole 15, and teeth 19 are provided on the lower side that engage with regulating teeth 20 provided on the base plate 2'. A fulcrum shaft 18 that enters the connecting fulcrum hole 15 is provided on the base plate 2, and the fulcrum lever 14 can jump over the engagement of the regulating teeth 20 and the teeth 19 and change the engagement position at will around this fulcrum shaft 18. It's summery. Also, the continuous fulcrum hole 15 is connected to the fulcrum shaft 18.
It is possible to slide against the An elongated hole 16 is formed on the opposite side of the sliding plate 12 from the movement fulcrum, and a pin 6 is provided on the arm 5 formed integrally or separately in the wind direction plate 1, and this pin 6 is connected to the sliding plate 12. The sliding plate 12 is inserted into the elongated hole 16 and connected, and the sliding motion of the sliding plate 12 is transmitted to the wind direction plate 1. At this time, the wind direction plate 1 is supported by substrates 2, 2' arranged in parallel at the upper and lower ends of the air outlet and shafts 3, 3' of the wind direction plate 1.

To explain the operation of the wind direction changing device configured in this way, the fulcrum lever 14 is positioned around the fulcrum shaft 18 at an arbitrary meshing position by overcoming the meshing of the teeth 19 and the regulating teeth 20. At this time, the moving fulcrum 21 moves around the fulcrum shaft 18. Further, when the eccentric cam 13 rotates within the guide groove 17 of the vibrating plate 12, the sliding plate 12 slides about the moving fulcrum 21. This sliding motion is transmitted through the elongated hole 16 to the pin 6 of the arm 5 of the wind direction plate 1.
At this time, if you want to increase or decrease the wind direction angle, as shown in FIG. When the distance is made small, the wind direction angle becomes large, and conversely, when the distance between the moving fulcrum 21 and the motor shaft 10 is made large, the wind direction angle becomes small. Next, if you want to change the wind direction from side to side, rotate the fulcrum lever 14 as shown in Figure 4 and move the moving fulcrum to the right, the wind direction will turn to the left; conversely, if you want to change the wind direction to the right, move the fulcrum lever 14. By moving 21 to the left, the wind direction can be turned to the right.

[Effect of idea]

As mentioned above, this idea consists of an arm with pins molded into multiple wind direction plates, a plate with a guide groove into which an eccentric cam can be inserted, and a tooth that connects to the sliding plate and meshes with the regulating tooth. Equipped with a fulcrum lever that can be displaced by the fulcrum shaft, and an eccentric cam placed in the guide groove of the sliding plate, the wind direction and angle can be freely changed, so it is compatible with the situation, usage, and requirements of the room in which the air conditioner is installed. The purpose of the present invention is to provide a compact wind direction changing device that can change the wind direction and wind direction angle according to the situation and is easy to operate.
