Abstract

PURPOSE:To uniformize temperature distribution and improve the comfortable property of a living space employing an air-conditioning machine upon starting the cooling operation thereof by cooling a human body directly in the initial period of operation, thereafter, cooling the wall surfaces of the space or the like. CONSTITUTION:The title air-conditioning machine maximizes the capacity of a compressor 17 upon starting the cooling operation thereof and drives an airflow deflecting vane 1 downward, the airflow deflecting vanes 5a, 5b rightward and leftward. In this case, the blow-off air of the machine is concentrated downward and cool air is collided against a human body direct. When a time has elapsed in some degree, the capacity of the compressor 17 is reduced, the deflecting vanes 5a, 5b are driven oppositely to obtain downward distributed blow-off air to cool the circumference of the human body as well as the wall surfaces of a room. When the time of operation has elapsed further, the capacity of the compressor 17 is minimized and the deflecting vane 1 is driven upward. In this case, the blow-off air is distributed horizontally and comfortable room cooling effect may be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lice 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, there is a device in which the upper and lower deflection blades are squeezed at regular intervals. (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 the left and right deflection is manual, so only a limited space can be cooled. There wasn't. Another problem was that the temperature distribution in the room deteriorated. Furthermore, since the air squirts from the start of operation, there is a problem in that the cold air does not hit the human body when the air conditioner cools down, making it impossible to obtain a sufficient cooling effect.

An object of the present invention is to improve the comfort of a living space using an air conditioner, particularly to improve the comfort at the start of cooling operation.

Means for Solving the Problems In order to solve the above problems, the present invention compresses a refrigerant,
An indoor unit that includes a variable capacity compressor, a blower, and the indoor heat exchanger that constitute a refrigeration cycle together with an indoor heat exchanger and an outdoor heat exchanger; an air outlet that blows out the air that has passed through the air outlet; a vertical deflection blade that vertically deflects the air that is blown out from the air outlet; and air that is provided independently on the left and right sides of the air outlet and that is blown out from the air outlet. left and right deflection blades that branch and deflect in left and right directions, and drive means that independently drive deflection of the upper and lower deflection blades and the left and right deflection blades, respectively; -- #;! ! :IVJtX The capacity of the compressor is controlled by a compressor rotation speed variable means, an elapsed time detecting means for detecting the elapsed time from the time when the air conditioner performs a certain operation, and a preset time memorized. a set time storage means;
The elapsed time detected by the elapsed time detection means when the vertical deflection vane and the left and right deflection vanes are in a state where the air is directed downward and concentrated from the outlet, and when the capacity of the variable capacity compressor is at its maximum. detects that has reached the first elapsed time stored in the set time storage means, the vertical deflection blades maintain the above state, and the left and right deflection blades move from a concentrated position to a position where they diverge to the left and right. The system rotates the variable capacity compressor, reduces the capacity of the variable capacity compressor, detects that a second elapsed time has elapsed since the start of the set operation, and moves the vertical deflection blade horizontally or upwardly from the downward direction. The compressor is further provided with a signal generating means for giving a signal to the drive means and the rotation speed variable means to rotate the variable capacity compressor to a position such that the variable capacity compressor has a minimum capacity.

Operation With the above configuration, the air deflection device of the air conditioner of the present invention concentrates the compression function downward at the maximum when the air outlet temperature is high at the start of the cooling operation, so that the cold air directly hits the human body and the cooling starts rapidly. Effects can be obtained.

In addition, after a certain period of time after the start of operation, the blowout temperature drops to a certain extent, causing discomfort when the cold air is applied directly to the human body. The air conditioner can cool the lower part of the room close to the living space without exposing it to heat, improving the experience. In addition, when the above operation exceeds a predetermined period of time, that is, when the blowout temperature drops, the compression function is minimized due to horizontal branching, allowing air to flow from the top to the bottom of the room without direct cold air, resulting in near-natural cooling. It is possible to obtain effects and reduce power consumption.

Embodiment Hereinafter, a wind direction deflection device for an air conditioner according to an 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,
A vertical deflection blade 1 that performs vertical wind direction deflection by the Coanda effect has a shaft 2 in its longitudinal direction, and this shaft 2 is connected to an intermediate motor (stepping motor) 3. The left and right deflection blades that horizontally deflect the blown air by the Coanda effect are composed of a left deflection blade 5a connected to a connecting bar 4a and a right deflecting blade 5b connected to a connecting bar 4b. And the left deflection blade 5a is
Feather lever arm 6a, rod 7a.

The right deflection blade 5b 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 6b10.

It is connected to a right motor (stepping motor) 9b via a motor lever arm 8b. Here, left deflection blade 5
a is slightly curved so that its center is to the left of this left deflection blade 5a, and right deflection blade 5b is slightly curved so that its center is to the right of this right deflection blade 5b. That is, both sides 13a of the air outlet 12, which will be described later,
13b to cause the aforementioned Coanda phenomenon and deflect the wind direction. Since the Coanda effect is a well-known technique, its explanation will be omitted.

In this embodiment, the driving means is composed of the middle motor 3, the left motor 9&, 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, it is also possible to control the upper and lower deflection blades 1 and the left and right deflection blades with a single motor.

Further, the motor is not limited to a stepping motor, but may be an induction motor or the like. In addition, the reason why the left and right deflection blades are divided into two parts, the left deflection blade 5 & and the right deflection blade 5b, is that it is possible to easily carry out 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, it may be further divided into smaller sections, or conversely, it may be connected by a single connecting bar 4 as shown in FIG. 2 without being divided. The left deflection blades 5 and 11 are curved to deflect the wind direction by the Coanda effect, as well as to enhance the concentration and separation effects that are the object of the present invention. If this is not taken into account, it may be a planar shape that is not curved, or it may even be a shape in which the opening 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.

In the figure, an indoor unit 10 has a suction port 11 on the front surface for sucking indoor air, and below the suction port 11 are vertical deflection blades 1 and left and right deflection blades 5a.

An air outlet 12 having a diameter 5b is provided. Both side portions 13a and 13b of the air outlet 12 are respectively curved surfaces that gradually expand outward in order to deflect the wind direction 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 side 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 a ventilation path from the indoor heat exchanger 15 to the outlet 12 .

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

In the figure, a variable capacity compressor 17, a 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, the refrigerant is supplied to the variable capacity compressor 17 during heating operation.
, the four-way valve 18, the indoor heat exchanger 15, the capillary tube 19, and the outdoor heat exchanger@20.
Variable capacity compressor 17, four-way valve 18, outdoor heat exchanger 20
, the capillary tube 19 and the indoor heat exchanger 15 in this order.

Here, a circuit diagram of the main part of this embodiment is shown in FIG.

The microcomputer 22 includes a storage unit 23 that stores a preset time, a signal generation unit 24 that generates an appropriate output signal by comparing the set value stored in the storage unit 23 with an input value, and It has a rotation speed variable means 25 for converting the signal generated by the generation means 24 into the rotation speed of the variable capacity compressor 17. On the input side of this microcomputer is a timer 21 which is a time detection means.
On the output side, there is a buffer 27 that supplies pulse output to each motor 3.9a, 9b and variable capacity compressor 17.
A middle motor 3, a left motor 9a, a right motor 9b, and a variable capacity compressor 17, which are driving means, are connected through the motor.

29 is a timer coil.

Now, to explain the relationship between the block diagram shown in FIG. 11 and the circuit shown in FIG. 6, the timer 21 shown in FIG. 6 is connected to the time detection means shown in FIG. 1
1, the signal generating means 24 in FIG. 6 corresponds to the signal generating means in FIG. 11, and the rotation speed variable means 25ξ in FIG. 6 corresponds to the rotation speed variable means in FIG. 11. However, each motor 3.9a, 9b in FIG. 6 corresponds to the driving means in FIG. 11.

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

The operating time t is the time detected by the timer 21 and is tl・
t2tIi is the set time. When this operating time t is less than the first set time 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;
The capacity of the variable capacity compressor 17 is maximized. Here, rotating the middle motor 3 to the left means moving the upper and lower deflection blades 1 to the lower position, and rotating the left motor 9a to the left means moving the left deflection blade 5 to the lower position.
Rotating a to the right and rotating the right motor 9b to the right indicates driving the right deflection blade 5b to the left. That is, the blown air is concentrated downward, as shown in FIG. 10. At this time, it is unclear what initial state the upper and lower deflection blades 1, left deflection blade 5a, and right deflection blade 5b are in, but each motor 3.9a.

After driving 9b, it always rotates to the above position. That is, when the deflection is already at the same position as the position after driving in the initial state, the motor is prevented from rotating by a load resistance such as a stopper, or the motor is caused to run idly. After each motor 3.9a, 9b rotates (
(before or during rotation as necessary), set timer 2 again.
Compare the time of 1 and the set time.

Next, if the time t of the timer 21 has passed the first set time or more and is less than the second set time t2, the middle motor 3 is rotated to the left, the left motor 9a is rotated to the right, and the right motor 9b is rotated to the left. and stop. Also, the capacity of the compressor 17 is reduced. That is, the blown air becomes a downward branch, as shown in FIG. Before this operation, when the deflection blades are already concentrated downward in FIG. 10, only the left and right deflection blades 5a and 5b are deflected.

Next, when the timer 21 reaches the second set time t2 or more, the middle motor 3 is rotated clockwise, the left motor 9a is rotated clockwise, and the right motor 9b is rotated counterclockwise and stopped. is the minimum. That is, the blown air becomes horizontally divided as shown in FIG.

By performing the above operation, when the temperature of the air outlet is high such as at the start of operation, the compression force is concentrated downward, as if direct cold air is applied to the human body, and after a certain amount of time has passed and the temperature of the air outlet has cooled down. becomes a downward branch of the compression function to indirectly cool the human body, and when enough operating time has passed and the outlet temperature is low enough, it becomes a horizontal branch of the compression function to cool the entire room.

The effect of such an operation at the start of cooling operation will be explained. First of all, since the air temperature at the start of cooling operation is high, 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 increased. Therefore, it is preferable to apply wind directly to the human body. That is, U
f: A cooling effect that can cool the human body more quickly is achieved by blowing air concentrated downward with a large contraction function.

Next, when a certain amount of time has passed and the blowout temperature has decreased, the compression jIk capacity is set to medium rather than high, and the blowout is directed downward, so that cooling can be performed to cover the lower part of the room near the living space. That is, by cooling the area around the human body and cooling the wall surface, the temperature distribution within the living space can be made uniform.

When the operating time further passes and the blowout temperature becomes lower, the compressor function becomes horizontally divided, so a sufficient cooling effect can be obtained without directly blowing cold air to the human body. That is, in the initial stage, the human body is directly cooled, and the walls and the like are later cooled, so that the temperature distribution is uniform, and there are no local hot spots in the living space. Also, power consumption is reduced.

Effects of the Invention As is clear from the description of the above embodiments, when the time from the start of operation is shorter than a certain set time, the compression function force is strongly concentrated downward, so that the air is directly applied to the human body, resulting in a sensory effect. can be increased to obtain a faster falling effect.

Next, when the above-mentioned operating time reaches a certain set time, the flow is diverted downward during the compression function, so that the temperature distribution in the living space can be made uniform in order to cool the wall surface without impairing the bodily sensation.

When the operation continues and the second set time is reached, the compression function is horizontally divided, making the temperature distribution even more uniform, eliminating local hot spots, and at the same time blowing cold air from above. Provides a comfortable cooling effect. Also,
Since the compression function is reduced, power consumption can be reduced.
