DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction adjusting device for adjusting the direction of air flow and an air conditioner using the same.

[0002]

2. Description of the Related Art A conventional wind direction adjusting device in which a plurality of movable blades are connected and integrally formed is disclosed in, for example, Japanese Patent Application Laid-Open
Examples described in JP-A-1-121913 are also included. In this example, the shafts of a plurality of movable blades are integrally formed in a shaft hole formed as a part of the cavity of the outer frame, so that the assembly of the movable blades becomes unnecessary.

[0003]

In the above prior art, assembling of the movable blade is simplified, but it is necessary to devise a special mold to integrally mold the movable blade, and the molding becomes complicated.
In addition, after fitting a plurality of movable blades one by one into the mounting hole, then fitting one by one into the connecting rod, the number of parts,
There is a problem that the number of assembly steps increases.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, simplify molding, reduce the number of assembling steps, and stably maintain the position of the movable blade (wind direction in an air conditioner). It is an object of the present invention to provide a wind direction adjusting device with improved stability of adjustment operation and an air conditioner using the same.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned object, the present invention is directed to a spring part which is connected to a connecting rod on a side surface and is integrally formed of synthetic resin, and an upper side spring for attaching the spring part. And, in a wind direction adjusting device having a lower horizontal spring arranged in parallel with the upper horizontal spring, a part which becomes thinner in a wedge shape and connects the spring part and the connecting rod, and a lower surface of the spring part A cylindrical insertion portion that is provided and inserted into the upper horizontal spring, a fixed nail provided in a protruding shape on the outer peripheral surface of the cylinder at the tip of the insertion portion, and an upper side between the fixed nail and the lower surface of the spring portion is A leaf spring provided with a portion that is inclined with respect to the surface into which the spring portion is inserted to provide spring properties.

[0006] As a result, since the spring portion is integrally formed, the number of parts can be reduced, and in assembly, a plurality of the spring portions can be twisted together with respect to the connecting rod, and inserted into the upper horizontal spring. In addition, the number of parts and the number of assembly steps can be reduced. In addition, since the spring portion has a spring property with respect to the surface into which the splash portion is inserted, a frictional force is generated between the splash portion and the upper horizontal spring, and the value may be larger than the blowing force. The position of the (spring), that is, the wind direction in the air conditioner, can be stably maintained.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention for an indoor air conditioner will be described below with reference to FIGS. 1 is a perspective view of a wind direction adjusting device according to an embodiment, FIG. 2 is a front view thereof, FIG. 3 is a plan view thereof, FIG. 4 is a side view thereof, and FIG. 6 is a plan view of the same spring portion, FIG. 7 is a side view of the same spring portion, and FIG. 8 is a plan view showing the upper horizontal splash of one embodiment.

The upper horizontal spring 2 adjusts the vertical direction of the indoor air blown from the indoor blower, and is arranged in parallel with the lower horizontal spring. Provided. The vertical spring 1 is integrally formed of a synthetic resin having excellent elongation, and is connected by a plurality of spring portions 1a and connecting rods 1b. The connecting part 1e of the spring part 1a and the connecting rod 1b is set so that a part thereof becomes thinner in a wedge shape, and the spring part 1a and the connecting rod 1b are easily bent so as to have flexibility. The restoring force of the spring 1a can be adjusted by the wedge-shaped dimension. Further, a portion of the lower surface of the spring portion 1a to be inserted into the upper horizontal spring 2 has a columnar shape, and a protruding fixing claw 1d is provided at the tip of the cylindrical outer peripheral surface. The angle at which the fixed pawl 1d is provided on the spring portion 1a matches the angle of the mounting hole 2a of the upper horizontal spring 2, and a plurality of fixed pawls 1d are inserted into the mounting hole 2a while twisting with respect to the connecting rod.

A plurality of fixed pawls 1 of the inserted vertical spring 1
Due to the recovery force from the torsion, each d rotates around the PP, and the fixed pawl 1d is caught inside the surface of the upper and lower springs 2 into which the vertical springs are inserted, and serves as a fastener.

From the above, the vertical spring 1 can be attached to the upper horizontal spring 2, the inclination of the mounting hole 2a of the upper horizontal spring 2 is set to s ° with respect to the vertical direction, and the twist of the spring portion 1a is performed. When the angle is t °, s> t / 2 makes it possible to reliably prevent the vertical spring 1a from coming off during operation.

The contact portion of the spring portion 1a with the upper and lower springs 2 is provided with a portion which is inclined with respect to the surface into which the spring portion 1a is inserted, to form a leaf spring 1c having spring properties. I have.

As a result, a frictional force is generated between the spring 1 and the upper horizontal spring 2, and the frictional force can be made larger than the recovery force of the spring portion 1a and the connecting rod 1b and the wind force. The position (wind direction) can be stably maintained. Furthermore, leaf spring 1
If the shape of c is a square roof, the portion in contact with the upper horizontal spring 2 can be widened, so that more frictional force can be obtained, and the stability of the vertical spring 1 during operation is better. can do.

[0013]

According to the present invention, since the vertical spring is integrally formed without making the mold special, the molding is simplified, and the number of parts is reduced.
Assembly man-hours can be reduced. In addition, since the surface into which the vertical splash is inserted has a spring property, a frictional force is generated between the vertical splash and the upper and lower splashes, and the position of the movable blade (vertical splash), that is, air conditioning It is possible to stably maintain the wind direction in the machine and improve the stability of the operation of adjusting the wind direction.
