Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wind direction deflection method 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 that has blow-off ports in the horizontal and vertical directions, and blows out in the horizontal direction when the blow-out temperature is lower than the set temperature, and blows out in the vertical direction when the blow-out temperature is higher than the set temperature. (Japanese Patent Publication No. 55-10813) That is, the configuration of this first conventional example prevents so-called cold draft, and can enhance the heating effect.

Furthermore, in order to improve the comfort in a large living space, there is a device that squeaks left and right deflection blades and upper and lower deflection blades at regular intervals. (US Pat. No. 3,257,931) This second conventional example is shown in FIGS. 11 and 12.

In the figure, the front part of the Suita mouth 101 includes upper and lower 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.
is provided. The upper and lower deflection blades 102 are connected to the bellows 10 through a connecting bar 105a and a lever arm 106a.
7alC connected. In addition, left and right deflection blades 103.1
04 is a bellows 107b via connecting bars 105b, 105c and lever arms 106b, 106c, respectively.

107c. In addition, each bellows 107a,
Heaters 108a and 10 are installed in 107b and 107c, respectively.
8b and 108c are wound.

Reference numeral 109 denotes a microswitch that controls energization of the heaters 108a1108b and 108c.

In the above configuration, heaters 108a and 108b.

By energizing 108c, the bellows 107a1
107b and 107c are expanded, and the expansion of the bellows 107b operates the microswitch to operate the heater 108a,
Power supply to 108b and 108c is stopped. As a result, bellows 107a.

107b and 107c are cooled and contracted.

By repeating this operation, the effect of fluctuating the blown air can be obtained.

Problems to be Solved by the Invention However, the conventional configuration as described above has the following problems.

Even if the air in the living space is heated to a predetermined temperature by the air conditioner during heating, the walls of the room being heated do not have enough heat source due to heat conduction with the outside air and the heat capacity of the walls themselves.

Therefore, when the air reaches a predetermined temperature or higher and the air conditioner is stopped by the temperature controller, the temperature of the living space rapidly decreases due to the walls.

In addition, in order to solve the above problem, if hot air is constantly deflected between the living space and the wall, the speed of the hot air hitting the human body will change significantly (+11JL), causing discomfort to the human body due to the fluctuations in wind speed. There was a problem of giving.

In the first conventional configuration, the hot air blown from the air conditioner is directed in one direction, so the wall is not sufficiently warmed by the hot air.

Furthermore, although the second conventional configuration is capable of deflecting the airflow in the horizontal direction, it deflects the air to the left and right at regular intervals, and the wall surface cannot be sufficiently heated. Although it can heat the living space, there is a problem that the warm air does not reach the living space sufficiently, which impairs comfort.

In addition, in the second conventional configuration, the hot air is constantly deflected to the left and right,
Since the speed of hot air hitting the human body fluctuates widely, there is a problem in that the fluctuating wind speed causes discomfort to the human body.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an indoor unit having an air blower and an indoor heat exchanger therein, and an indoor unit provided in the indoor unit that allows the air passing through the indoor heat exchanger to an air outlet, vertical deflection blades that vertically deflect the air blown from the air outlet, and vertical deflection blades that are provided independently on the left and right sides of the air outlet and branch the air blown from the air outlet in the left and right directions; left and right deflection blades that deflect the air, and drive means that independently deflect and drive the upper and lower deflection blades and the left and right deflection blades, and a drive means that deflects the upper and lower deflection blades and the left and right deflection blades, respectively, and the air conditioner that has elapsed time since the air conditioner performed a certain operation has reached a predetermined value. and an output means for outputting an output to the driving means, and when the elapsed time reaches a predetermined value, the air blowing direction is changed to a direction in which the air blowing direction before the elapsed time reaches the predetermined value is a horizontal direction and branches to the left and right. If so, change it to a downward and concentrated direction and hold it for a certain period of time, or if it is a downward and concentrated direction, change it to a direction that branches left and right in the horizontal direction and hold it for a certain period of time. , this is repeated by the output of the output means [u
J.

Effect: By using the above means, the method for deflecting the wind direction of an air conditioner of the present invention changes the blowing direction of the air conditioner horizontally when the elapsed time from the time when the air conditioner performs a certain operation reaches a predetermined value. In addition, the direction is branched to the left and right, and the direction is concentrated downward, and this direction is alternately repeated and held in each direction for a certain period of time, so there is little reduction in comfort due to fluctuations in the wind speed of the hot air hitting the human body. In addition, since the walls of the room being heated are sufficiently warmed as necessary, even if the air conditioner is stopped by the temperature controller, the living space will not be rapidly cooled by the walls. As a result, comfort can be improved.

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,
The vertical deflection blade 1, which deflects the wind direction 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 (steve 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. The left deflection blade 5a is connected to a left motor (stepping motor) 9a via a blade lever arm 6a, a rod 7a, and an N-morph 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 right motor (stepping motor) 9b via a morph 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 generate the above-mentioned Coanda effect and deflect the wind 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 the motor with a single motor.

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 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, 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. In addition, the left deflection blade 5a and the right deflection blade 5b are curved in shape to not only deflect the wind direction by the Coanda effect but also to enhance the concentration and splitting effects that are the object of the present invention.
Unless the Coanda effect is taken into account, the shape may be a planar shape that is not curved, or even a shape in which the four directions of the dog are reversed.

Next, FIG. 4 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 a suita port 12 having a vertical deflection blade 1 and left and right deflection blades 5a and 5b is provided below the suction port 11. . Both sides 13a of this outlet 12
, 13b are curved surfaces that gradually expand outward in order to deflect the wind direction by the Coanda effect as described above. - Also, as mentioned 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, FIG. 6 shows the refrigeration cycle of this embodiment.

In the figure, a compressor 17, a four-way valve 18, an indoor heat exchanger 15, a capillary tube 19, and an outdoor heat exchanger 20 are connected in a ring. Here, during heating operation, the refrigerant is
The air flows in the order of compressor 17, four-way valve 18, indoor heat exchanger 15, capillary tube 19, and outdoor heat exchanger 20, and during cooling operation, compressor 17, four-way valve 18, and outdoor heat exchanger 20.
, the cavity tube 19 and the indoor heat exchanger 15 in this order.

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 time, 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. There is.

On the input side of the cono microcomputer, a timer 21, which is a time detection means, is connected in parallel with the compressor 17, which is operated by a phase advance capacitor 28, and is connected to each motor 3.9a, 9.
A middle motor 3, a left motor 9a, and a right motor 9b, which are drive means, are connected via a buffer 26 that supplies pulse output to the drive means.

Here, 29 is a timer motor coil.

Here, to explain the relationship between the block diagram shown in FIG. 3 and the circuit shown in @7, the timer 21 in FIG. 7 corresponds to the time detection means in FIG. This corresponds to the set time storage means in the figure, and the drive signal generation means 2 in FIG.
4 corresponds to the IK drive signal generating means in FIG. 3, and each motor 3.9a, 9b in FIG. 7 corresponds to the drive 0J means in FIG.

Next, the operation of this embodiment is shown in Figure @8. This figure is a flowchart during heating operation.

T is the elapsed time since the compressor 17 was operated, and T1・T
2 is the setting time. When this elapsed time T is shorter than the first set time T1, the middle motor 3 is rotated clockwise, the left motor 9 is rotated clockwise, and the right motor 9b is rotated counterclockwise and then stopped. Here, rotating the middle motor 3 to the right means moving the upper and lower deflection blades 1 to the horizontal position, and if necessary, moving the left motor 9a to the upper position.
Rotating the right motor 9b to the right means driving the left deflection blade 5a to the left, and rotating the right motor 9b to the left means driving the right deflection blade 5b to the right. That is, the blown air becomes horizontally divided as shown in FIG. At this time, it is unclear what initial conditions the upper and lower deflection blades 1, left deflection blade 5a, and right deflection blade 5b are in, but each motor 9a,
After driving 9b19c, 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 not allowed to rotate by a load resistance such as a stopper, or the motor is made to idle. and each motor 9a, 9b.

After the rotation of step 9c, the elapsed time and the set time are compared again before or during the rotation as necessary.

Next, if the elapsed time is longer than the first set time T1 and less than the second set time T2, 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 stop. In other words, the blown air is concentrated downward and the first
The result will be as shown in Figure 0. Next, when the elapsed time becomes longer than the second set time, the time kakunt is returned to zero, and the time kakunt is counted again, and the above operation is repeated.

The effect when such an operation is performed during heating operation will be explained. First, by blowing hot air horizontally, the walls of the room are warmed, and even if the air conditioner is stopped by the temperature controller, the room temperature will not drop rapidly due to the walls. In addition, since the hot air is blown out in a downward direction, the heating effect can be enhanced by directing the air to the human body.

The hot air is repeatedly blown out in the two directions mentioned above, but since it is maintained for a certain period of time when blown out in each direction, there is little rapid change in wind speed to the human body, and there is no discomfort to the human body.

The warm air blows out horizontally in a horizontal direction, creating a heating effect from around the room, warming the walls and the area around them.

When performing downward concentrated air blowing, the heating effect is performed from the center of the room, giving a feeling of heating by directing the air to the human body, and creating a locally cool space by the action of the heated walls. do not have.

Therefore, by repeatedly performing heating from these two directions while maintaining it for a certain period of time, the temperature distribution within the living space can be made uniform.

Effects of the Invention As is clear from the description of the above-mentioned embodiments, the walls of the room are warmed by blowing warm air horizontally, and even if the air conditioner is stopped by the temperature controller, the wall quickly warms the air. The room temperature never drops. In addition, since the hot air is blown out in a downward direction, the heating effect can be enhanced by directing the air to the human body. In addition, each hot air is repeatedly blown out in the two directions mentioned above, but since it is held for a certain period of time when blown out in each direction, there is less discomfort to the human body due to rapid changes in wind speed, and as a result, comfortable heating is achieved. be able to.
