Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner suitable for an air conditioner such as a car air conditioner for automobiles, as well as an air conditioner for indoor cooling and heating for homes and businesses.

[0002]

2. Description of the Related Art In the case of various air conditioners and fans that have been conventionally used, it is possible to adjust the amount of wind force stepwise, but the adjusted blast is sent in a uniform and unbalanced condition and hits the human body. , Sometimes with discomfort.
In recent years, air-conditioning equipment that introduces fluctuation control called fuzzy control, for example, has become widespread in order to eliminate such problems and realize air blowing close to natural wind, so-called “fluctuation style”.

[0003]

However, in this type of air conditioning equipment, in order to control the rotation of the fan motor of the blower to artificially form the strength and weakness of the blast and the fluctuating wind, complicated control of the motor rotation speed is required. Circuits and arithmetic circuits were required, which resulted in product cost.

Therefore, an object of the present invention is to provide a wind control device which can form a comfortable air flow for a human body with a simple structure.

[0005]

In order to achieve this object, a wind control device according to the present invention comprises a main body frame which is detachably attached to the inside of a blower duct by elastic engagement and whose mounting position can be adjusted, and which is rotated by the main body frame. A fan that is supported so that it can be swung, and a wind control plate that is swingably supported by the body frame via a swing shaft that is orthogonal to the rotation shaft of the fan, and a conversion that converts the rotation of the fan into swing of the wind control plate. It has a structure including a mechanism.

[0006]

[Operation] The fan of the wind control device rotates in the air duct.
The rotation of the fan is converted into swing of the wind control plate through the conversion mechanism. By changing the strength of the air blow by swinging the wind control plate,
It creates a fluctuating wind that is close to the natural wind.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a wind control device according to the present invention will be described below with reference to the drawings. Here, the use mode is particularly described assuming a combination with a cooling and heating air conditioner, but it is also applicable to blast cooling and warm air drying of semi-finished products in other food manufacturing processes and the like.

FIG. 1 and FIG. 2 are a side sectional view and a plan sectional view showing a mode in which the wind control device 10 of the embodiment is mounted in the blower duct 1, and FIG. 3 is a main part of the wind control device 10. It is a perspective view. The wind control device 10 is unitized, and the air duct 1
It can be freely attached and detached at any place.

That is, the apparatus 10 has a main body frame 11, and the main body frame 11 is provided with snap arms 11a which are curved and formed as shown in the drawing so that the elastic snap can be used. The elasticity of the snap arms 11a is utilized. It is adapted to be inserted into the blower duct 1 and snap-engaged inside. It can be removed if necessary. A fan 12 is rotatably supported on the front portion of the body frame 11. In the embodiment, the fan 12 is a blade type fan that rotates by receiving air blown from another air blower (indicated by an arrow a in FIGS. 1 and 2) in the air blow duct 1. May be a blower.

Since the fan 12 may rotate at a higher speed than necessary depending on the blowing strength, in the embodiment, the rotary shaft 13 of the fan 12 is connected to the speed reducer 14 so that the fan 12 can be decelerated to a required speed. It is supported by the main body frame 11 via the speed reducer 14. Reducer 14
The output side of is connected to a conversion mechanism having the following configuration according to the present invention via a rotary shaft 13, and the decelerated rotation of the fan 12 can be converted into the swing of the wind control plate 20 via this conversion mechanism.

The conversion mechanism is composed of a pair of driving and passive bevel gears 15a, 15 connected to the end of the rotary shaft 13.
and a passive side bevel gear 15b is rotatably supported by a bracket 16, and a crank arm 17 is provided on the gear shaft.
Are connected so that they can rotate together. One end of a long crank lever 18 is connected to the other end of the crank arm 17 by a pin 19. A wind control plate 21 is connected to the other end of the crank lever 18 via a crank pin 20. The crank pin 20 is a fixed pin fixed to the wind control plate 21 side, and is engaged with an elongated hole 18 a provided in the crank lever 18. The baffle plate 21 is swingably supported via a swing shaft 22 in a direction intersecting the blower duct 1, that is, in a direction orthogonal to the rotation shaft 13 of the fan 12, and the swing shaft 22 is provided at both ends thereof. The bearing 23 supports the main body frame 11.

Next, the operation and action of the wind control system of the embodiment having the above construction will be described.

The wind control device 10 is formed as a unit, and the air duct 1 is inserted by utilizing the elasticity of the snap arm 11a, and is attached to the inside by snap engagement. In the blower duct 1, the blower a from the blower is sent, and the fan 12 of the wind control device rotates in response to the blower a.

The rotation of the fan 12 is reduced to a required rotation by the speed reducer 14. The decelerated rotation of the fan 12 is converted into swing of the wind control plate 21 via a conversion mechanism. That is, the rotation of the fan 12 is decelerated and then transmitted to the pair of bevel gears 15a and 15b on the driving side and the passive side,
It is transmitted from the passive bevel gear 15b to the crank arm 17 on the shaft. The rotation of the crank arm 17 is transmitted to the crank lever 18 at the other end. Crank arm 1 accompanying rotation
The change in the length of the crank lever 18 and the crank lever 18 added to the axial distance is absorbed by the relative movement between the long hole 18a on the crank lever 18 side and the crank pin 20 on the wind control plate 21 side. When established, the wind control plate 21 swings.

That is, the fan 12 is rotated by the flow of the air blow a in the air blow duct 1, and this rotation causes the wind control plate 21 to swing, so that the air blow a is throttled in the duct. The air discharged from the air is not uniform, and if the air is cold or warm air, it will continue to flow strongly, weakly, and strongly to provide a comfortable air flow to the human body.

In the present invention, the mechanism for decelerating the rotation of the fan 12 and converting it into the swing of the wind control plate 21 is not limited to the mechanism shown in the embodiment, but a cam or the like is used for the crank movement. Various mechanisms described above can also be applied.

[0017]

As described above, the wind control device according to the present invention is particularly suitable for the air conditioners for air conditioning and heating, and the complicated electronic control is required to control the fluctuation of the comfortable air flow to the human body. With a simple mechanism that does not require, for example, it can be easily installed in any place of the existing air duct by unitization, and by adjusting the strength of the air blown from the air duct, fluctuations close to natural wind can be achieved. Can form wind.
