[Problems to be solved by the device]

 The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide an air conditioner capable of reliably maintaining a state in which an exhaust port is closed by a wind direction changing body.

[0009]

[Means for Solving the Problems]

 According to a first configuration of the present invention, an airflow direction changing body, which can be opened and closed, is rotatably disposed at an exhaust port, and a distance from a rotation center of the airflow direction changing body to a tip of the airflow direction changing body is set as a wind direction. It is characterized in that it is formed longer than the distance from the rotation center of the changer to the exhaust port edge.

A second structure of the present invention is to form a wind direction changing body which is supported by being rotatably supported by inserting a pivot shaft into a pivot hole formed in an edge of an exhaust port. An elastic piece having a locking projection is formed on either one of the shafts, and an engaging portion for engaging the locking projection is formed on the other of the pivot hole and the pivot shaft. Is formed with a spring body that presses in a direction to engage with the engaging portion.

According to a third aspect of the present invention, a wind direction changing body that is rotatably supported is formed by inserting a pivot shaft into a pivot hole formed at an exhaust port edge, and the pivot shaft is pivotally supported. It is characterized by the provision of a spring body that presses against the hole.

[0012]

[Action]

 According to the first configuration, the tip of the airflow direction changing member comes into contact with the edge of the exhaust port to prevent the airflow direction changing member from rotating due to its own weight and prevent the exhaust port from opening. When the airflow direction changing member is rotated when the exhaust port is opened, the airflow direction changing member is deformed to overcome the contact with the exhaust port edge, and the airflow direction changing member is oriented in a desired direction.

According to the second configuration, since the elastic piece presses the locking projection in the direction of engaging the engaging portion with the spring body, the locking projection and the engaging portion are reliably engaged. ..

According to the third configuration, since the pivot body pushes the pivot shaft into the pivot hole by the spring body, the frictional resistance between the pivot portion and the pivot hole can be increased, and the wind direction changing body can be placed at any position. It will be held securely.

【Example】

 A first embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2. It should be noted that the same parts as those of the conventional one are designated by the same reference numerals and the description thereof will be omitted.

Reference numeral 20 denotes a wind direction changing body disposed in the second exhaust port 5, and the pair of left and right pivot shafts 21 are inserted into the pivot holes 22 formed at the edges of the second exhaust port 5 facing each other to rotate. It is supported freely. The wind direction changing body 20 is composed of the first wing piece 23 and the second wing piece 24, the first wing piece 23 closes the second exhaust port 5, and the second wing piece 24 is the second exhaust gas. It is designed to open and close between a position where the air passage leading to the mouth 5 is closed and a position where the second blade 24 closes the air passage leading to the first exhaust port 4. Reference numeral 25 denotes a projecting portion formed substantially at the center of the front end of the second blade 24 in the left-right direction. The distance from the rotation center O of the wind direction changing body 20 to the tip of the projecting portion 25 is defined by the wind direction changing body 20. Is formed to be larger than the shortest distance from the rotation center O to the front side edge of the second exhaust port 5 and the second exhaust port 5 is closed by the wind direction changing body 20, the tip of the protrusion 25 is the second exhaust port. The length is formed so as to be close to or in contact with the front side edge of the mouth 5.

Reference numeral 26 denotes an elastic piece formed on the pivot shaft 21 of the wind direction changing body 20, which is a locking projection that selectively engages with a plurality of engaging portions 27 formed at the edge of the pivot hole 22 at the tip. 28, and the first protrusion 23 closes the second exhaust port 5 by the engagement of the locking projection 28 and the engagement hole 27, and the second blade 24 closes the second exhaust port 5. 2 The position where the air passage to the exhaust port 5 is closed, the position where the second blade 24 closes the air passage to the first exhaust port 4 and a proper number of positions between the two positions are maintained. Is becoming

In the state where the second exhaust port 5 is closed by the wind direction changing body 20, the wind direction changing body 20 is formed to be heavier on the rear side than the rotation center O, so that it may rotate to the rear side by its own weight. However, the distance from the tip of the protrusion 25 formed at the front end of the second wing piece 24 of the wind direction changing body 20 to the rotation center O is from the rotation center O to the front side edge of the second exhaust port 5. Since the wind direction changing body 20 tries to rotate rearward due to its own weight, the projecting portion 25 of the second blade 24 abuts the edge of the second exhaust port 5 and the wind direction changing body is formed. The rotation of 20 is restricted, and the wind direction changing body 20 keeps the second exhaust port 5 completely closed.

When the airflow direction changing body 20 is rotated when opening the second exhaust port 5, the protruding portion 25 of the second blade piece 24 comes into contact with the front side edge of the second exhaust port 5 and the second blade. The piece 24 bends, and the protrusion 25 rides over the front side edge of the second exhaust port 5. Then, the wind direction changing body 20 is directed to an arbitrary position and blows air in a desired direction.

The second embodiment will be described in detail with reference to FIG. The same parts as those in the conventional example and the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Reference numeral 29 denotes a protruding rib formed substantially at the center of the front side edge of the second exhaust port 5 in the left-right direction, and measures the distance from the rotation center O of the wind direction changing body 20 to the front side end of the wind direction changing body 20. In a state in which it is formed to be larger than the shortest distance from the rotation center O of the changing body 20 to the tip of the protruding rib 29, and the second exhaust port 5 is closed by the wind direction changing body 20, the tip of the protruding portion 25 has the second exhaust port 5 The length is formed so as to be close to or in contact with the front side edge.

In the state where the second exhaust port 5 is closed by the wind direction changing body 20, the wind direction changing body 20 is formed to be heavier on the rear side than the rotation center O, so that it may rotate to the rear side by its own weight. However, the distance from the front end of the second wing piece 24 of the wind direction changing body 20 to the rotation center O is determined by the shortest distance from the rotation center O to the protruding rib 29 formed at the front side edge of the second exhaust port 5. Since it is formed large, when the wind direction changing body 20 tries to rotate rearward due to its own weight, the front end of the second wing piece 24 abuts the protruding rib 29, and the rotation of the wind direction changing body 20 is restricted, and the wind direction changing body 20 is restricted. The changing body 20 keeps the second exhaust port 5 completely closed.

When the airflow direction changing body 20 is rotated when the second exhaust port 5 is opened, the second blade 24 is bent by the second rib 24 coming into contact with the protruding rib 29, and the second blade 24 is bent. Piece 24 rides over protruding rib 29. Then, the wind direction changing body 20 is directed to an arbitrary position to blow air in a desired direction.

In the first embodiment, the protrusion 25 is formed at the front end of the second wing piece 24 of the wind direction changing member 20, and the protrusion 25 is brought into contact with the front side edge of the second exhaust port 5. The rotation of the wind direction changing body 20 is restricted, and in the second embodiment, a protruding rib 29 is formed at the front side edge of the second exhaust port 5 so as to abut against the front side end of the wind direction changing body 20. A protrusion may be formed on the rear side end of the first wing piece 23 of the wind direction changing body 20, and the protrusion may be brought into contact with the rear side edge of the second exhaust port 5, or the rear side of the second exhaust port 5. You may form the protrusion part which contacts the 1st blade piece 23 rear side edge part of the wind direction change body 20 in an edge.

A third embodiment of the present invention will be described in detail below with reference to FIGS. 4 to 6. The same parts as those of the conventional example and the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Reference numeral 30 is a ring-shaped metal spring body fitted and inserted into the inner peripheral edge of the pivot shaft 21 of the wind direction changing body 20, and is constantly urged in the expanding direction.

The elastic piece 26 formed on the pivot shaft 21 of the wind direction changing body 20 is formed in the direction in which the locking projection 28 projects to the outer periphery by the spring body 30, that is, in the pivot hole 22. Even when the airflow direction changing body 20 is kept in a position where the locking projection 28 does not engage with the engaging portion 27 for a long period of time, as shown in FIG. The restoring force of the piece 26 and the spring body 30 does not decrease. Therefore, as shown in FIG. 4, when the wind direction changing body 20 is rotated to the position where the second exhaust port 5 is closed, the locking protrusion 28 surely engages with the engaging portion 27, and the second exhaust gas is discharged. Make sure to maintain the closed state of the mouth 5.

Further, since the spring body 30 is formed in a ring shape and is inserted and fitted to the inner peripheral edge of the pivot shaft 21, the elastic piece 26 is not expanded beyond the inner peripheral edge of the pivot shaft 21. In addition, the elastic piece 26 is not damaged.

As shown in FIG. 7, the spring body 30 may have one end inserted into a locking hole formed in the pivot shaft 21 to regulate the rotational movement of the spring body 30.

Further, in the third embodiment described above, the elastic piece 26 is formed on the pivot shaft 21 of the wind direction changing body 20, but the elastic piece is formed on the pivot hole 21, and the engaging portion is formed on the pivot shaft 21. You may form in. A fourth embodiment of the present invention will be described in detail below with reference to FIGS. 8 and 9. The same parts as those of the conventional example and the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

Reference numeral 31 is a pivot shaft integrally formed with the wind direction changing body 20, and is composed of a plurality of arcuate portions 32. Reference numeral 33 denotes a ring-shaped spring body that is fitted and inserted into the inner peripheral edge of the pivot shaft 31, and is constantly urged in the expanding direction to press the arcuate portion 32 of the pivot shaft 31 against the edge of the pivot hole 22. It is like this.

Thus, the arcuate portion 32 of the pivot 31 is pressed against the edge of the pivot hole 22 by the urging force of the spring body 33 to increase the rotational frictional force between the pivot 31 and the pivot hole 22. .. Therefore, the wind direction changing body 20 is securely held at an arbitrary position.
