Abstract

PURPOSE:To prevent a user from being given unpleasant sensations due to the direct striking of cold air against the user and to the rapid change in air speed by a method wherein the air is repeatedly blown off during cooling in three directions or in downward divided flows, in horizontal divided flows and in a horizontal concentrate flow and each direction is held for a certain period of time. CONSTITUTION:A vertically deflecting vane 1, left deflecting vanes 5a and right deflecting vanes 5b are driven in relation to the elapsed time since the running of a compressor and the set time so as to repeatedly blow off the air in the respective directions or the downward divided flows, in horizontal divided flows and in the horizontal concentrate flow and to keep each blowing-off direction for a certain period of time. Concretely, first, the blowing-off of the air in downward divided flows lowers the temperature of the air in a living space without striking a user with cold air. Secondly, the blowing-off of the air in horizontal divided flows cools the walls of rooms located at the right and left of an air conditioner. Finally, the blowing-off of the air in a horizontal concentrate flow cools the wall of a room opposing to the air conditioner. Accordingly, even when a temperature regulator stops an air conditioner no rapid rise of room temperature occurs.

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) 38 In other words, the f:/f configuration of the first conventional example prevents the so-called cold draft by 1.1), so that the heating effect can be enhanced.

Furthermore, in order to improve comfort in the spacious living space, left and right f4I! There is a device that swings the vertical deflection blade 414 at a constant period. (U.S. Patent No. 3257
931) This second conventional example is shown in FIGS. 11 and 12.

In the figure, the front surface of the air outlet 101 includes two lower deflection blades 102 that deflect the blown air in the vertical direction, and left and right deflection blades 103 and 10 that deflect the blown air in the horizontal direction.
4 are provided. The upper and lower deflection blades 102 are connected to the bellows 1 via a coupling device 105a and a lever arm 106a.
07a. In addition, the left and right deflection blades 103,1
04 are connected to the bellows 107b, 107c via coupling devices 105b, 105G, lever arms 106b, 106c, respectively. Also, each bellows 07a, 107b, 107c has a heater 108a, 108b and 108c are wound.

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

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

By energizing 108c, the bellows 107a,
107b and 107c expand, and the expansion of the bellows 107b operates the microswitch.
Stop power supply to 108b and 108c. As a result, the bellows 107a, 1071) 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 when the air in a living space is lowered to a predetermined temperature by an air conditioner during cooling, the walls of the room being cooled are not sufficiently cooled due to heat conduction with the outside air and the heat capacity of the walls themselves.

Therefore, when the air falls below a predetermined temperature and the air conditioner is stopped by the temperature controller, the temperature of the living space rapidly rises due to the walls.

Furthermore, in order to solve the above problem, if the cold air is constantly deflected between the living space and the wall, the wind speed of the cold air hitting the human body will fluctuate to a large extent, causing discomfort to the human body due to the fluctuation in wind speed. ! , j(t).

When a cooling operation is performed with the first conventional configuration, the cold air blown out from the air conditioner is directed in one direction, so that the wall is not sufficiently cooled by the cold air.

In addition, when performing cooling operation with the second conventional configuration, although it is possible to deflect the airflow in the horizontal direction, there is a problem that the airflow direction is changed to the left and right (fi + i plane) at a constant cycle, and the wall surface cannot be sufficiently cooled. there were.

In addition, in the second conventional configuration, the cold air is constantly deflected from side to side,
In addition, since the cold air is also deflected toward the lower central part, which is the direction of the living space, the wind speed of the cold air that hits the human body fluctuates over time, causing discomfort to the human body due to the fluctuation in wind speed.

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 a means for solving the above-mentioned indoor heat exchanger. An air outlet that blows out the air that has passed through the air outlet, vertical deflection blades that vertically deflect 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. a left and right deflection blade that branches and deflects the air in the left and right directions; a driving means that independently drives the upper and lower deflection blades and the left and right deflection blades to deflect the air; an output means for outputting an output to the driving means when the elapsed time reaches a predetermined value; If the direction is downward and branched to the left and right, change to the horizontal direction and branch to the left and right, and hold this for a certain period of time, and if the direction is horizontal and branch to the left and right, change the direction to the horizontal direction and branch to the left and right. The direction of concentration is maintained for a certain period of time, and the direction is repeatedly driven by the output of the output means.

Operation With the above configuration, the air conditioner wind direction deflection device 7' of the present invention lowers the air blowing direction of the air conditioner when the elapsed time from the time when the air conditioner performs a certain operation reaches a predetermined value. A direction branching to the left and right in the direction, a direction branching horizontally to the left and right, and a direction being horizontal and concentrated, and repeating this alternately and holding this for a certain period of time in each direction, so that it hits the human body. G), where there is little decrease in comfort due to changes in the wind speed of cold air.

Furthermore, even if the air conditioner is stopped by the temperature controller to sufficiently cool the walls of the room being cooled, the living space will not be rapidly heated by the walls.

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 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 vane (1), which performs vertical wind direction in one plane by the Coanda effect, has a shaft 2 in its longitudinal direction, and this shaft 2 is connected to a middle motor (stepping motor) 3. The left and right deflection blades that deflect the horizontal direction by the Coanda effect are composed of a left deflection blade 5a connected to a coupler 4a, and a right deflection blade 5b connected to a coupler 4b.The left deflection blade 5
a is the lever arm 5a for the blade, and the Ron door a.

It is connected to a left motor (stepping motor) 9a via a motor 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 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 120, 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 middle motor 3 and the left motor 9a.

9... The right motor 9b constitutes the drive means ()'4, but it is also possible to use one motor to drive the left and right deflection blades.
Furthermore, by using a switching means such as a gear or a clutch, 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 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, all the sections may be connected by a single connector 4 as shown in FIG. In addition, the left deflection blade 5a and the right deflection blade 5b are curved to deflect the wind direction by the Coanda effect, and also to enhance the concentration and separation effect that is the object of the present invention. If this is not taken into consideration, it may be a planar shape that is not curved, and furthermore, the opening directions may be reversed.

10. 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 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 sides 13a and i3b 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, 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 compressor 17, the four-way valves 18, 11 flow in the order of the indoor heat exchanger 15, the capillary tube 19, and the outdoor heat exchanger 20, and during cooling operation, the compressor 17, the four-way valve 18, the outdoor heat exchanger 20, Capillary 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.

The input terminal of this microcomputer is connected in parallel with a compressor 17 operated by a timer 21 serving as a detection means or a phase advance capacitor 28, and each motor 3,9
The left motor 9a and the right motor 9b are connected to the middle motor 3°, which has a 100-degree return motion, via a buffer 26 that supplies pulse output to the motors 9a and 9b.

Here, 29 is a morke coil for a timer.

Here, to explain the relationship between the block diagram shown in FIG. 3 and the circuit shown in FIG. 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.
Reference numeral 4 corresponds to the drive signal generating means in FIG. 3, and each motor 3, 9a in FIG.

9b corresponds to the driving means in FIG.

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

T is the elapsed time since the compressor 17 was operated, and T1.
T2, T3, and Tn-T (n-1) are set times.

When this elapsed time T is shorter than the first set time T1, 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 then stopped. Here, rotating the middle motor 3 to the left moves the upper and lower deflection blades 1 to the lower position, rotating the left motor 9a to the right moves the left deflection blade 5a to the left, and rotating the right motor 9b to the left moves the right deflection blade 5b. Indicates that it is driven to the right. That is, the blown air becomes a downward branch as shown in FIG. At this time, the upper and lower deflection blades 1, left deflection blade 5a, and right deflection blade 5b are moved to 13.

Although it is not known what state each motor is in, it is certain that each motor 9a, 9b, 9c will rotate to the above position after being driven. That is, when the deflection is already at the same position after driving in the initial state, the rotation of the motor is not affected by a load resistance such as a stopper, or the motor is allowed to rotate idly. And each motor 9a, 9b,
After the rotation 9c (before or during rotation as required), the elapsed time and the set time are compared again.

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 clockwise, the left motor 9a is rotated clockwise, and the right motor 9b is rotated counterclockwise and stopped. do. That is, the blown air becomes horizontally divided as shown in FIG.

Next, the set time T is longer than the second set time T2, and the third set time T is longer than the second set time T2.
If it is shorter than the setting lRt, the middle motor 3 is rotated clockwise, the left motor 9a is rotated counterclockwise, and the right motor 9b is rotated clockwise and then stopped. That is, the blown air becomes horizontally concentrated as shown in FIG. Also, Tn from TI and T2
A sufficient interval of 14 vanes is provided between each set time, and each motor has a sufficient stopping time after rotation. Each motor repeatedly performs the above operation.

The effect when such an operation is performed during cooling operation will be explained.

First, by blowing cold air downward, the temperature of the air in the living space is lowered without directing the cold air to the human body.

Next, by distributing the cold air horizontally, the walls of the room on either side of the air conditioner can be cooled.

Finally, the wall of the room facing the air conditioner can be cooled by blowing out the cold air in a horizontally concentrated manner.

The cold air is repeatedly blown out in the three directions mentioned above, but the wind is not blown out directly into the living space, and the air is kept blown out in each direction for a certain period of time, so there is no discomfort caused by the cold air hitting the human body directly. No discomfort caused by rapid wind speed fluctuations.

Since the cold air is blown in the three directions to cool the wall surface, even if the air conditioner is stopped by the temperature controller FUI, the room temperature will not rise rapidly due to the warm walls.

Moreover, by repeatedly blowing cold air in the three directions, the temperature distribution in each part of the room is improved.

Effects of the Invention As is clear from the description of the above embodiments, the present invention repeatedly blows cold air in three directions: downward division, horizontal division, and horizontal concentration, and maintains this for a certain period of time in each direction, thereby blowing cold air directly to the human body. It does not cause discomfort due to blowing or rapid changes in wind speed.

Furthermore, by blowing cold air in the three directions mentioned above, the walls of the room are cooled, and even if the air conditioner is repeatedly stopped, the room temperature will not rise rapidly due to the warm walls.

Furthermore, by blowing out the cold air in the three directions, the temperature distribution in each part of the room is improved.
