Abstract

PURPOSE:To improve feeling during room cooling operation, by a method wherein a signal for turning up-and-down deflecting vanes from downward position to upward position is given to a driving means when detecting temperature has arrived at a set temperature. CONSTITUTION:When indoor temperature, detected by a thermistor 21, is higher than a set temperature, stored in a memory 23, during room cooling operation, a micro-computer 22 for air conditioning enables a middle motor 3 and a left motor 9a to rotate counterclockwise and a right motor 9b clockwise by a signal from a driving signal generating means 24 to position an up-and-down deflecting vane 1 downwardly and position left and right deflecting vanes 5a, 5b inwardly to concentrate blow-off cool air downwardly. Subsequently, when the indoor temperature decreases to the set temperature, the middle motor 3, the left motor 9a and the right motor 9b are rotated reversely respectively to turn the up-and- down deflecting vane 1 upwardly and the left and right deflecting vanes 5a, 5b outwardly, whereby the blow-off air is branched upwardly. Thus, the improvement of temperature distribution as well as the feeling of the cooling operation may be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a wind direction deflection device for controlling the blowing direction of an air conditioner.

BACKGROUND OF THE INVENTION Until now, various devices have been devised as wind deflection devices for air conditioners in order to improve the comfort of living spaces.

For example, to improve comfort in a large living space,
There is a device in which the left and right deflection blades and the top and bottom deflection blades are squeezed at a constant period (U.S. Pat. No. 3,257,931).

This conventional example is shown in FIGS. 11 and 12. Air outlet 101
The front surface of the air conditioner is provided with vertical deflection blades 102 that deflect the blown air in the vertical direction, and left and right deflection blades 103 and 104 that deflect the blown air in the horizontal direction. The upper and lower deflection blades 102 are connected to the coupling machine 105a and the lever arm 106.
It is connected to the bellows 107a via a. In addition, the left and right deflection blades 103 and 104 are connected to the coupling machine 105b, respectively.
, 105C, and lever arms 106b, 106c, are connected to bellows 107b, 107C. Furthermore, heaters 108a, 108b, and 108C are wound around each bellows 107g, 107b, and 107c, respectively.

109 are heaters 108a and 108b.

This is a microsinch that controls the energization of 108c.

The above M5M, the heaters 108a and 108b.

By energizing 108c, the bellows 107a,
107-1107G expands, and the expansion of the bellows 107b operates the microswitch, causing the heaters 108a,
Power supply to 108b and 108c is stopped. As a result, the bellows 107a, 107b, and 107G are cooled and contracted.

By remanipulating this motion, the effect of fluctuating the blown air can be obtained.

Problems to be Solved by the Invention However, although the above configuration allows the airflow to be deflected in the horizontal direction, the airflow is switched regardless of the airflow temperature or operation mode, and if the upper and lower deflection blades are facing downward, the airflow cannot be directly hit by the wind. Even when there is no wind blowing, the human body is exposed to the wind, which gives a bad feeling especially when the temperature is stable, and the temperature distribution in the living space is also poor.

An object of the present invention is to improve the comfort of a living space using an air conditioner, particularly to improve the comfort when the room temperature is stable during cooling operation.

Means for Solving the Problems In order to solve the above problems, the present invention provides a compressor that compresses a refrigerant and constitutes a refrigeration cycle together with an indoor heat exchanger and an outdoor heat exchanger, a blower, and the indoor heat exchanger. an indoor unit having an indoor unit therein; an air outlet provided in the indoor unit that blows out the air that has passed through the indoor heat exchanger; and a vertical deflection blade that vertically deflects the air blown out from the air outlet; Left and right deflection blades that are provided independently on the left and right sides of the air outlet and that branch and deflect the air blown out from the air outlet in the left and right directions; and a drive that independently drives the vertical deflection blades and the left and right deflection blades to deflect them respectively. means and
temperature @Hatake means for detecting the suction temperature from the suction port;
A set temperature storage means stores a preset temperature, and the temperature detected by the temperature release means is stored in the set temperature storage means in a state where the upper and lower deflection blades are positioned so that air from the air outlet is directed downward. and a drive signal generating means for supplying a signal to the drive means to rotate the vertical deflection blade from the downward position to the dirt floor when it is detected that the set temperature has been reached.

Effect Due to the above-mentioned collapse, the air direction deflection device of the air conditioner of the present invention changes from downward blowing to upward blowing when the suction temperature reaches a certain set temperature, so when the air conditioner starts up, the cold air directly hits the human body, which tends to make the person feel cold. B. When the room temperature is stable, the cold air does not directly hit the human body, so the person does not feel cold, and the cold air comes down from the upper part of the living space, improving the temperature distribution and feeling. Also, since the air blows upward, the noise of the air blowing can be reduced.

Embodiment F From now on, a wind direction deflection device for an air conditioner according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of the main parts of the device. As shown in the figure, the vertical deflection blade 1, which is slightly curved in the blowing direction and deflects the wind upward and downward by the Coanda effect, has a shaft 2 in its longitudinal direction, and this shaft 2 is connected to a medium motor (stepping motor). )3. In addition, the left and right deflection vanes that deflect the blown air in the horizontal direction by the Coanda effect are the left deflection vanes 5 connected to the coupler 4a.
a, and a right deflection blade 5b connected to a connecting device 4b. The left deflection blade 58 is connected to the left motor (stepping motor) 9a via a blade lever arm 6850 throat 7a and a motor lever arm 8a.
The right deflection blade 5b has a blade par arm 6b and a rod 7.
b. It is connected to the right motor (stepping motor) 9bK via the motor arm 8b. Here, the left deflection blade 5a is slightly curved so that its center is to the left of this left deflection blade 5a, and the right deflection blade 5b is slightly curved so that its center is to the right of this right deflection blade 5b. are doing. That is, both sides 1 of the air outlet 12 described later
3a and 13b to generate the above-mentioned Coanda phenomenon and deflect the wind direction.

Since the Coanda effect is a well-known technique, the invention will be omitted.

In this embodiment, the driving means is composed of the middle motor 3, the left motor 9a, and the right motor 9b, but it is also possible to use a single motor for driving the left and right deflection blades, and it is also possible to use gears, clutches, etc. By using a switching means, the upper and lower deflection blades 1 and the left and right deflection blades are controlled by a single motor.

Further, the motor is not limited to a stepping motor, but may be an induction motor or the like.

It is also conceivable to use a shape memory alloy spring, which deteriorates depending on the ambient temperature, for the motor spring, and the reason why the left and right deflection vanes are divided into two, the left deflection vane 5a and the right deflection vane 5b, is that the present invention This is because the desired concentration and diversion operations can be easily performed, and the wind direction can be controlled independently.
In order to perform more delicate control of the wind direction, the structure may be further divided into smaller sections, or conversely, the structure may be connected by a single coupling device 4 as shown in FIG. 2 without being divided. Furthermore, the reason why the left deflection blade 5a and the right deflection blade 5b are curved is to create a shape that enhances the concentration and splitting effect that is the object of the present invention in a pond that deflects wind direction by the Coanda effect, and takes into consideration the Coanda effect. If not, it may have a planar shape that is not curved, or it may even have a shape in which the round directions are reversed.

Next, FIG. 3 shows a perspective view of the indoor unit 10 to which the wind direction deflection device shown in FIG. 1 is installed. The indoor unit 10 has a suction port 11 on the front surface for sucking indoor air, and below the suction port 11 there are vertical deflection blades 1, left and right deflection blades 5a,
An air outlet 12 having a diameter e5b is provided. Both sides 13a and 13b of the air outlet 12 have curved surfaces that gradually expand in order to deflect the wind direction outward by the Coanda effect as described above. Further, as described above, the lower surface portion 14 is also a curved surface that gradually expands in order to deflect the wind direction by the Coanda effect.

A cross-sectional view of this indoor unit 10 is shown in FIG. An indoor heat exchanger 15 is provided at a position facing the suction port 11 , and a blower 16 is provided in the ventilation path from the indoor heat exchanger 15 to the air outlet 12 .

Next, the refrigeration cycle of this embodiment is shown in FIG.

A compressor 17 four-way valve 1B, an indoor heat exchanger 15, a capillary tube 19, and an outdoor heat exchanger 20 are connected in an annular manner. Here, during heating operation, the refrigerant is supplied to the compressor 17, the four-way valve 1B, the indoor heat exchanger 15, and the capillary tube 19.
, the outdoor heat exchanger 200 in this order, and during cooling operation, it flows in the order of the compressor 17, the four-way valve 18, the outdoor heat exchanger 20, the capillary tube 19, and the indoor heat exchanger 15.

Next, a circuit diagram of the main part of this embodiment is shown in FIG. The microcomputer 22 includes a storage section 23 that stores a preset temperature, and a drive signal generation means 24 that generates an appropriate output signal from a comparison between the set value stored in the storage section 23 and an input value. IL. A boomister 21 which is a detection means is connected to the input side of this microcomputer via a converter 25, and each motor 3.9a is connected to the output side of the microcomputer.
, 9b, the middle motor 3, the left motor 9a, and the right motor 9b, which are drive means,
is connected. Here, 27 is a bias resistance, and 2nd is a scan resistance.

Next, the operation of this embodiment is shown in FIG. This figure is a flowchart during cooling operation. Suction temperature t is Boomister 21
tl is the temperature detected at , and tl is the set temperature. When this suction temperature t is higher than the set temperature t1, the middle motor 3 is rotated to the left, the left motor 9a is rotated to the left, and the right motor 9b is rotated to the right and then stopped.

In the figure, rotating the middle motor 3 to the left means moving the upper and lower deflection blades fully downward (to the hydraulic position if necessary), and rotating the left motor 9a to the right means moving the left deflection blade 5a to the right side and the right motor 9b. Rotating to the right indicates driving the right deflection vane to the left.

In other words, the blown air is concentrated downward, as shown in FIG. At this time, the upper and lower deflection blades 1, the left deflection blades 5a
, right deflection vane 5b, respectively, are not known in what initial state they are in, but after each motor 9a, 9b, 9c is driven, they always rotate to the position 11'q as described above.

That is, when the deflection is already at the same position as the position after driving in the initial state, the motor cannot be rotated due to load resistance such as a striker/bar, or the motor is rotated idly. After each motor 9a, 9b, 9c rotates (
Before or during rotation, if necessary, the temperature of the Pumisk 21 and the set temperature are compared again.

Next, when the temperature t blown out from the Pumisk 21 reaches the preset temperature t1, the middle motor 3 is rotated clockwise, the left motor 9a is rotated clockwise, and the right motor 9b is rotated counterclockwise and then stopped. In other words, the blown air becomes an upward branch flow. In this case, the left and right blade positions may be left with no action and the balloons may be concentrated upward.

By performing the above actions, υ, when the air conditioner starts up, the cold air hits the human body directly, so there is a cold air 1δ, and when the room temperature is stable, the wind does not directly hit the human body, so you do not feel cold and the living space is reduced. Since cold air comes down from the second part, it is possible to improve the temperature distribution and the feeling. Since the wind still blows upwards, the blowing noise can also be reduced.

Note that similar effects can be obtained by using a plurality of set temperatures and a plurality of corresponding upper and lower blade setting positions.

Effects of the Invention As is clear from the description of the above embodiments, when the intake temperature reaches a certain set temperature, the air blows from the bottom to the top, so when the air conditioner starts up, the cold air hits the human body directly, resulting in a feeling of cold air. When the room temperature is stable, the wind does not directly hit the human body, so you do not feel cold, and the cold air comes down from the upper part of the living space, improving the temperature distribution and feeling.

Furthermore, since the air is blown upward, it has various advantages such as reducing air blowing noise.
