Description

DETAILED DESCRIPTION OF THE INVENTION Field of Application on 1f-R 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, single-layer devices have been considered as wind deflection devices for air conditioners in order to improve the comfort of living spaces.

For example, there is a device that swings the upper and lower deflection blades at a constant cycle. (Japanese Patent Publication No. 56-21149) Problems to be Solved by the Invention However, the conventional configuration described above can only control the deflection in the vertical direction, and since changing the left side is only an aid, it is difficult to use in a limited space. There was a problem that the temperature distribution in the room where only cold labor could be done worsened. In addition, since air swing occurs from the start of operation, there is a problem in that cold air does not hit the human body when the air conditioner starts up, making it impossible to obtain a sufficient cooling effect.

The present invention aims to improve the comfort of a living space using an air conditioner, and particularly to improve the comfort at the start of cooling operation.

Means for Solving the Problems In order to solve the problems, the present invention provides a rotary variable pressure 51 inlet A that compresses a refrigerant and constitutes a refrigeration cycle together with an indoor heat exchanger and an outdoor heat exchanger. an indoor unit in which the indoor heat exchanger is installed; an air outlet provided in the indoor unit for blowing out the air that has passed through the indoor heat exchanger; vertical deflection blades that deflect the air in the vertical direction; left and right deflection blades that are independently provided on the right and left sides of the air outlet and that branch and deflect the air blown out from the air outlet in the left and right directions; A driving means for independently driving the deflection blade and the left and right deflection blades, and a temperature sensor for detecting the temperature of the air outlet.
and a rotation speed variable means for changing the rotation speed of the compressor. In this state, when the temperature of the blown air reaches a first predetermined shift, the left and right deflection vanes are driven so that the blown direction is bifurcated, and the rotation speed of the cavitation machine is set to medium speed. Further, when the blowing air temperature reaches a second predetermined value, the vertical deflection blades are driven so that the blowing direction is upward, and the blowing capacity is set to medium to small. This changes the rotation speed of the compressor.

Effect: By using the above method, when the air outlet temperature is high, such as at the start of cooling operation, the compression function is at its maximum in the lower part of the air, so the cold air hits the human body directly, resulting in a unique cooling effect. In addition, if the temperature of the air outlet has dropped to a certain extent and the cold air is applied directly to the human body, it will cause discomfort, but if the temperature of the living space is sufficiently low, if the compression function is set to medium and the flow is diverted downward,
The air conditioner wraps around the lower part of the room near the living space, improving the experience and shortening the start-up time. Also,
If the blowout temperature falls below the above level, even if the air is diverted downward, the cold air will hit the human body, causing discomfort and the air will become horizontally separated, and the rotational speed of the compressor will change from medium to low, resulting in medium to low capacity. Therefore, the temperature of the entire room can be lowered uniformly without applying cold air directly to the human body, so the sensation is the same as above, and a sufficient cold effect is achieved. In addition, it is possible to reduce the marketing power.

EXAMPLE Hereinafter, a wind direction deflection device A for an air conditioner according to one embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is an exploded perspective view of the main parts of the device.

As shown in the figure, it is slightly curved in the direction of the balloon,
The upper and lower deflection blades 1, which perform the same deflection on the upper and lower sides by Coanda effect capture, have a shaft 2 in the longitudinal direction thereof, and this shaft 2 is connected to an intermediate motor (stepping motor) 3. Further, the left and right deflection vanes that deflect the blown air/air in the horizontal direction by the Coanda effect are composed of a left deflection vane 5a connected to a coupler 4a, and a U deflection vane 5b connected to a coupler 4b. . and left deflection blade 5
a is a blade lever arm 6a and a rod 7a.

It is connected to a left motor (stepping motor) 9a via a motor lever arm 8a, and the right deflection blade 5b is connected to a blade lever arm 6b and a rod 7b.

It is connected to a stepping motor 9b via a motor lever arm 8b. Here left planar wing 11
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 centered to the right of this right deflection blade 1-15b and generates the Coanda effect of the front 6, This is a t-comme that will be sent to one direction. Since the Coanda effect is a well-known technique, its explanation will be omitted.

In this embodiment, the middle motor 3 and the left motor 9a.

Although the right motor 9b constitutes the driving means, it is also possible to use a single motor for driving the left and right deflection blades, and furthermore, by using a switching means such as a gear or a clutch, the upper and lower deflection blades 1 and the left and right deflection blades can be switched. It is also possible to control this with a single motor.

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

It is also possible to use a shape-memory alloy spring that changes depending on the ambient temperature instead of the motor, and in this case, the whole a itself must have temperature detection means and set temperature storage means, which are essential requirements of the present invention. become. Furthermore, the reason why the left and right deflection blades are divided into two parts, the left deflection blade 5a and the right deflection blade 5b, is to facilitate the concentration and separation operations that are the object of the present invention, and also to be able to independently control the wind direction. ,
In order to perform more delicate control of the wind direction, a structure may be adopted in which the profit is divided further, or conversely, the structure may be connected by a single connecting rod 4 as shown in FIG. 2 without being divided.

Furthermore, the left deflection blade 5a and the right deflection blade 15b are curved to deflect the wind direction by the Coanda effect, and also to enhance the concentration and splitting effect that is the object of the present invention. As long as the shape is not curved, it may be a planar shape that is not curved, and furthermore, it may be a shape in which the horizontal directions are reversed.

Next, FIG. 31 shows a perspective view of the indoor unit 10 in which the wind deflector Δ shown in FIG. 1 is installed. In the figure, the front of the indoor unit 10 has a suction port 1 that sucks indoor static electricity.
1, and an air outlet 12 having upper and lower deflection blades 1 and left and right deflection blades 145a and 5b is provided below the suction port 11. Both side portions 13a and 13b of the air outlet 12 are curved to gradually expand outward in order to deflect the wind direction by the Coanda effect as described above. Further, the lower part 14 has a curved shape that gradually expands in order to deflect the wind direction by the Coanda effect as described above.

A 5fr side view of this indoor unit 10 is shown in FIG. An outdoor heat exchanger 15 is provided on one side opposite to the suction port 11, and a blower 16 is placed 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.

In the figure, a variable rotation speed compressor 17, a four-way valve 1B,
An indoor heat exchanger 15, a capillary tube 19, and an outdoor heat exchange j120 are connected in an annular manner.

Here, the refrigerant is supplied to the variable speed compressor 17 during heating 4-turn.
, four-way valve 18, indoor heat exchanger 15, capillary tube 19, and outdoor heat exchanger 20, and during cooling operation,
Variable rotation speed compressor 17, four-way valve 18, outdoor heat exchanger 2
0, the capillary tube 19, and the indoor heat exchanger 15 in this order.

Here, 21a to 21d are temperature detection means that indirectly detect the temperature of the air outlet. That is, 21a is a temperature sensor that detects the pipe temperature of the indoor heat exchanger 15, and 21b is a rotation a
a four-flow detection device that detects the squirt flow of the ffiJ modified compressor 17;
21c is a pressure detector for detecting the discharge pressure of the variable rotation speed compressor 17, and 21d is a pressure detection record for detecting the distribution pressure of the outdoor heat exchanger 15Q). To detect the blowout temperature, 1, it is conceivable to provide a temperature sensor directly at the blowout port 12, but it can also be detected from the temperature, pressure, and 1st flow of each of the above parts, and any one of them can be selected or combined. It is also possible to use Further, 21e is a temperature detection temperature that detects the suction temperature, and is a temperature detection temperature of the room +? This is an example of a temperature detection means for detecting temperature a, and the room temperature detection location is not limited to the vicinity of the suction port.

Next, a circuit diagram of the main part of this embodiment is shown in FIG. Inside the microcomputer 22, there is a storage section 23 that stores a preset temperature, and a drive that generates an appropriate output signal from the set value stored in this storage section 23 and the input; It has a word generation means 24 and a rotation speed variable means 25 for converting the signal generated by the drive 1 word generation means 24 into the rotation speed of the rotation speed variable compressor 17. The input side of this microcomputer is heated via a comparator 26. Here, 28 is a bias resistor, and 29 is a scan resistor.

Here, to explain the relationship between the block diagram shown in FIG. 11 and the circuit diagram in FIG. 6, the thermistor 21 in FIG. 6 corresponds to the temperature detection means in FIG. 11, and the storage section 23 in FIG. This corresponds to the set temperature storage means in FIG. 11, and the driving signal generating means 24 in FIG. 6 corresponds to the driving 1 word generating means in FIG. 11, and corresponds to the driving means in FIG. do.

Next, the operation of this embodiment is shown in FIG. This figure is a flowchart during cooling operation.

The blowing temperature point is the temperature detected by the thermistor 21, and tl and t2 are the set temperatures. When this blowing temperature 1 degree t is hotter than the first set temperature t1 (in this case, the middle motor 3 is rotated to the left, the left motor 9a is rotated to the left, the right motor 9b is rotated to the right and stopped, and the rotation speed is changed. The number of revolutions of the mold compressor 17 is set to "4".
Rotation. Here, rotating the middle motor 3 to the left moves the vertical deflection blade 1 upward, rotating the left motor 9a to the left moves the left deflection blade 5a to the right, and rotating the right motor 9b to the right moves the left deflection blade 5a to the right. 1i5b is shown to be driven to the left. In other words, the blown air is concentrated downward and the 10th
The result will be as shown in the figure. At this time, it is not known what initial state the upper and lower deflection blades 1, left deflection blade 5a, and right flat blade 5b are in, but each motor 3, 9a, 9b
After the drive JjJ, it always rotates to the above position. That is, in the initial state, when the deflection is already at the same level as the position A after driving and toward the cliff, the motor is not rotated by a load resistance such as a stopper, or the motor is idled. Then, after each motor 3, 9a, 9b has rotated (before or during rotation, if necessary), the temperature of the thermistor 21 and the set temperature are again compared.

Next, if the temperature t of the thermistor 21 is lower than the first set temperature t1 and higher than the second set temperature t2, the middle motor 3
is rotated to the left, left motor 9& is rotated to the right, right motor 9b is rotated to the left, and then stopped. The rotation speed of the compressor 17 is set to medium speed rather than high speed. That is, the blown air becomes a downward branch as shown in FIG. 9.

Before this operation, when already in the downward concentrated state as shown in FIG. 10, the left and right deflection blades 5a are substantially the same.

Only 5b will be deflected.

Next, when the temperature t of the thermistor 21 is lower than the second set temperature t2, the middle motor 3 is rotated clockwise, the left motor 9a is rotated clockwise, and the right motor 9b is rotated counterclockwise and stopped.
7 is the low speed rotation. That is, the blown air becomes horizontally divided as shown in FIG.

By performing the above-mentioned i operation, when the blowing temperature is high such as at the start of operation, the cold air is compressed to 1 fH' to directly hit the human body. The force is concentrated downward, and when the blowout temperature is cooled to a certain extent, the compressive capacity becomes a downward branch to indirectly cool the human body, and when the blowout temperature is low enough, it cools the entire part. It becomes a horizontal branch of the compression function Cal.

The effect of such an operation at the start of cooling operation will be explained. First, since the air outlet temperature at the start of cooling operation is 1°, it will take too long for the air to cool down unless the air is applied directly to the human body and the compression function is controlled. Therefore, it is preferable to apply wind directly to the human body. In other words, by creating a downward concentrated blowout with a large compression function,
Provides a cooling effect that can cool the human body more quickly.

Next, when the blowout temperature becomes low to a certain extent, the compression function is changed from high to medium and the blowout is directed downward, so that the living space can be cooled so as to envelop the lower part of the hill portion 4. That is, by cooling the area around the human body and the wall surface, the temperature distribution within the living space can be evened out.

When the blowout temperature becomes even lower, the compressor function is horizontally divided, so a sufficient cooling effect can be obtained without directly blowing cold air to the human body.

That is, since the human body is initially cooled and the walls etc. are cooled later, the temperature distribution becomes uniform, and there are no hot spots in the living space. Also,
It will reduce the consumption gravity.

Effects of the Invention As is clear from the description of the above implementation sequence, when the blowing temperature exceeds a certain set temperature, the compression and functional power are concentrated downwards, so that the air is directly applied to the human body, resulting in a sensory effect of 8. A higher and faster rising effect is desired.

Next, when the blowout temperature reaches a certain set temperature, the compressor functions as a downward branch flow to cool the wall surface without impairing the user's sensation, making it possible to make the temperature distribution in the living space uniform.

Furthermore, when the blowout temperature is low, the compressor function becomes horizontally divided, making the temperature distribution even more uniform, eliminating local hot spots, and at the same time blowing cold air from above, increasing the comfortable cooling effect. 'Given. Also, since the compressor and knife are lowered, the amount of deer consumed can be reduced.
