Abstract

PURPOSE:To improve the temperature distribution of a residential space and comfortableness thereof by detecting and storing the position of a remote controller, and directing an air flow from a horizontal branch flow discharge to a stored direction when a discharge temperature or room temperature reaches a predetermined temperature value. CONSTITUTION:An infrared ray signal for detecting the position of a remote controller is received by a plurality of light receiving elements 22a, 22b and 22c to detect the position of a remove controller and to store the same. When a discharge temperature detected by a thermistor 21 is lower than a preset temperature, a middle motor is rotated clockwise, a left-hand motor 9a is rotated clockwise and a right-hand motor 9b is rotated the counterclockwise. In this case, the flow of discharge air becomes a horizontal branch flow. Then, when the temperature detected by the thermistor is higher than the preset temperature, the motors are rotated reversely. Then, the flow of discharge air is a horizontally concentrated. Thus, by detecting the position of the remove controller, a desired air flow direction position can be set instantaneously, and further is stored. Therefore, when the discharge temperature or room temperature reaches a predetermined temperature, it becomes possible to automatically direct a hot air flow or a cool air flow from the horizontal branch flow to a desired direction.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention 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 that squeaks the left and right deflection blades and the top and bottom deflection blades at regular intervals. (U.S. Patent No. 3257.931) The above conventional example is shown in FIGS. 15 and 16.
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 10.
6a to the bellows 107a. In addition, the left and right deflection blades 103 and 104 are connected to the coupling machine 105, respectively.
b.

105c, and are connected to bellows 107b, 107c via lever arms 106b, 106c. Furthermore, heaters 108a, 108b, and 108c are wound around each bellows 107a, 107b, and 107c, respectively. 10
9 are heaters 108a and 108b.

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

In the above configuration, heaters 108a, 108b, 108
By applying current to c, the bellows 107a, 107
b and 107c expand, and the expansion of the bellows 107b operates the microswitch to turn on the heaters 108a and 108.
b, stop supplying electricity to 108c. As a result, the bellows 107a, 107b, 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, in the conventional configuration described above, although the air outlet can be deflected in the horizontal direction, the air outlet is squeezed regardless of the air outlet temperature. The problem was that it could not be done.

Furthermore, as shown in Fig. 17, when the observation deck 10 is actually installed in a room, it is very rare that it is installed in the center C of the room, and it is installed at the left end a or the right end of the room. In most cases, For example, if the product is installed at the right end of the room, the center or left end of the room will have a poor temperature distribution (or will get cold) and will automatically direct the hot or cold air in the direction the user desires. I had the problem that even if I wanted to, I couldn't.

There is also a problem in that even if the camera is pointed at a certain point, the desired position must be set each time.

The present invention aims to improve the comfort and feeling of a living space using an air conditioner.

Means for Solving the Problems In order to solve the above problems, the present invention compresses a refrigerant,
An indoor unit that includes a compressor, a blower, and the indoor heat exchanger that constitute a refrigeration cycle together with an indoor heat exchanger and an outdoor heat exchanger, and air that is provided in this indoor unit and that has passed through the indoor heat exchanger. an air outlet that blows out air, vertical deflection blades that vertically deflect the air blown from the air outlet, and are provided independently on the left and right sides of the air outlet,
and left and right deflection blades that centrally branch and deflect air blown out from the air outlet in the left and right directions, and drive means that independently drive the upper and lower deflection blades and the left and right deflection blades, respectively;
drive signal generating means for providing a rotation signal to the drive means;
remote control position detection means for detecting the position of the remote control by receiving a signal transmitted from the remote control; detection position storage means for storing the position of the remote control detected by the remote control position detection means; and a blower from the air outlet. Equipped with temperature detection means for detecting temperature or room temperature, and set temperature storage means for storing a preset temperature,
At the same time as the signal transmitted from the remote control is received, the remote control position detection means detects the position of the remote control and stores the detected position in the detected position storage means, and the temperature detected by the temperature detection means is stored in the set temperature storage means. When the detected temperature is lower than the set temperature, the upper, lower, left and right deflection blades are driven so that the air blowing from the outlet is horizontal or upward and branched to the left and right, and when the detected temperature is higher than the set temperature, the detected position storage means is It drives the vertical, horizontal, and horizontal deflection vanes to the memorized positions.

Operation With the above configuration, the air conditioner wind deflection device of the present invention has the following effects:
The position of the remote control can be detected and memorized, and when the air outlet temperature or the room temperature reaches a certain set temperature, the air can be directed from the horizontal branch air outlet in the memorized direction. The air is mixed only in the left and right upper portions, making it possible to heat the room without feeling cold.

Furthermore, when the air outlet temperature is high, the air can be directed in a desired direction in the living space, thereby improving temperature distribution and comfort.

In addition, by moving the remote control, you can instantly deflect the wind direction to the desired direction, making the operation method very simple.

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, the vertical deflection blade 1, which is slightly curved in the blowing direction and deflects the wind direction by one step using the Coanda effect, has a shaft 2 in its longitudinal direction, and this shaft 2 is connected to a medium motor ( Stepping motor) 3 is not connected. The left and right deflection vanes that horizontally deflect the blown air by the Coanda effect are composed of a left deflection vane 5a connected to a coupler 4a and a right deflection vane 5b connected to a coupler 4b. And left deflection blade 5aid, blade lever arm 6a, rod 7a, motor lever arm 8
The right deflection blade 5b is connected to the left motor (steer, ping motor) 9a through a blade lever arm 6b, rod 7b, and motor lever arm 8b.
Stepping motor) 9b. 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, this is to cause the aforementioned Coanda phenomenon to occur on both sides 13a and 13b of the air outlet 12, which will be described later, and to 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 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, 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.

It is also conceivable to use a shape memory alloy spring that changes depending on the ambient temperature instead of the motor. In this case, the alloy itself will have temperature detection means and set temperature storage means, which are essential requirements of the present invention. 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, 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. The reason why the left deflection blade 5a and the right deflection blade 5b are curved is that in addition to deflecting the wind direction by the Coanda effect, the shape is to enhance the concentration and splitting effect that is the object of the present invention, and takes into consideration the Coanda effect. If not, it may be a planar shape that is not curved, or it may even be a shape in which the vertical 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 5b is provided. Both sides 13a and 13b of the air outlet 120 have 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. 5 shows the refrigeration cycle of this embodiment.

In the figure, a compressor 17, a four-way valve 18, an indoor heat exchanger 1
5. The capillary tube 19 and the outdoor heat exchanger 20 are connected in a ring. Here, during heating operation, the refrigerant 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, the refrigerant flows through compressor 17, four-way valve 18, outdoor heat exchanger 20, and exchanger 20,
It flows through 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 outdoor heat exchanger, 21b is a current detector that detects the current of the compressor 17, and 21c is the compressor 17.
21d is a pressure detector that detects the pressure of the pipes of the indoor heat exchanger 15.

In order to detect the temperature of the air outlet, it is conceivable to provide a temperature sensor directly at the air outlet 12, but the temperature of each of the above parts,
It can also be detected from pressure and current, and either one can be selected or used in combination. Also 21
e is an example in which the room temperature is detected by a temperature sensor that detects the suction temperature. However, the location where the room temperature is detected is not limited to the vicinity of the suction port but may be any location.

Next, the remote control position detection device will be explained.

FIGS. 6 and 7 are configuration diagrams of a remote control position detection device.

light Light receiving elements 22a and 22b of the pedestal section 22 in FIG.

22c are arranged in different directions (60
The light receiving element 22a has strong light receiving sensitivity for light from the incident direction, the light receiving element 22b for light from the B direction, and the light receiving element 22c for light from the C direction. have. Further, the light receiving elements of the control signal receiving section (not shown) are mounted on different surfaces, as in a conventional air conditioner, and have light receiving sensitivity over a wide range.

8 and 9 are block diagrams of the remote control position detection device.

In FIG. 9, the output current from the light receiving section 22 is amplified by amplifier circuits 23, 23b, and 23c, respectively, and input to tuning circuits 24a, 24b, and 24c.

This voltage is taken into the A/D intensity measurement circuit 29a of the microcomputer 28, and as an actual measurement value, comparison processing and calculation processing of each data are performed at the comparison calculation port 1129b, and the output signal is sent to the wind direction deflection plate drive circuit 29c. It is captured. 3.9a and 9b are stepping motors that drive the wind direction deflection plate, and are set to an arbitrary wind direction angle by a signal from the wind direction deflection plate drive circuit 29c.

Although the configuration of the remote control position detection device only in the left and right directions has been described above, the same applies to the up and down directions, so a description thereof will be omitted.

Next, the operation of this embodiment will be explained with reference to FIGS. 8 to 14.

First, when a control signal is transmitted from the remote control to the indoor unit 1o, the control signal receiving section receives it and inputs it to the signal decoding circuit of the microcomputer 28. If this signal is a signal other than a remote control position detection command, such as starting operation or switching a set temperature or air volume, the indoor unit 10 is controlled by the microcomputer 28 based on the control signal, and waits for a remote control transmission again. (Step 4).

When the control signal is a remote control position detection command, the remote control transmits an infrared signal for remote control position detection following the control signal, and the light receiving elements 22a, 22b, 22c attached to the indoor unit throat 10 are activated. This light is received (step 5).

The signals received by these three light receiving elements are amplified by amplifier circuits 23a, 23b, and 23c, respectively.
The amplified signal 25, via the tuning circuits 24a, 24b, 24c
26.27 (step 6). These amplified signals are input to the A/D intensity comparison circuit in the microcomputer 28, and the maximum value is selected first (step 7).
).

FIG. 12 shows the distribution of the light intensity obtained from each light receiving element when the position of the remote controller is moved based on the light receiving element current intensity.

When the remote control is transmitted from each direction A, B, and C as shown in FIG. 7, each light receiving element 22a as shown in FIG.
, 22b, 22c have the maximum intensity, and the intensity decreases as the direction shifts. The more the reception characteristics are almost the same, the more accurate the position can be compared with the light intensity. In this example, three light-receiving elements are used, each of which is shifted 60 degrees to the right, and the wind direction indication area is divided into five regions by setting the light intensity ratio of the three light-receiving elements. The system then controls the wind to blow into the detected area.

As shown in FIG. 12, in this embodiment, the position where the intensity ratio is 2:1 is set as the boundary of area division, and the algorithm is as shown in steps 7 to 10 of FIG. 10. In step 7, the element showing the maximum intensity among the three light receiving elements is classified as #4j.

Next, in steps 8 and 9, the condition judgment for determining each of the 5 areas is determined as the 5 areas of the final step 10 by calculating the intensity value, this is detected as the position of the remote control, and it is memorized ( Step 12).

Next, the blowing temperature t is the temperature detected by the thermistor 21, and tl is the set temperature. When the blowing temperature t is lower than the set 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 when the limit is reached, the motors are stopped.

Here, rotating the middle motor 3 clockwise means that the vertical deflection blade 1
in the horizontal position (in the upper position if necessary) and the left motor 9
Rotating a to the right indicates driving the left deflection blade 5a to the left, and rotating the right motor 9b to the left indicates driving the right deflection blade 5b to the right.

That is, the blown air becomes horizontally divided as shown in FIG. 13. After each motor 3.9a, 9b rotates (before or during rotation as required), the temperature t of the thermistor 21 and the set temperature t1 are compared again.

Next, when the temperature t of the thermistor 21 is higher than the set temperature t1, for example, if the remote control detection position is at the center and rear of the room, the middle motor 3 is rotated to the left, the left morph 9a is rotated to the left, and the right motor 9b is rotated to the right. Rotate and stop. That is, the blown air becomes horizontally concentrated as shown in FIG. 14.

By performing the above operation, the cold air that is not pleasant to the body is diverted horizontally so that it does not directly hit the human body, and when the temperature of the air outlet is high enough, it is concentrated downward so that it does not cause any harm even if it blows directly onto the human body. It becomes a speech bubble. The effect of such an operation at the start of heating operation will be explained.

First, since the temperature of the air outlet immediately after the start of heating operation is low, it is not desirable for the air to come into direct contact with the human body. Furthermore, even if the air within the living space does not directly hit the human body, the air within the living space will feel lower than the actual room temperature, so it is preferable that the movement of the air within the living space be small.

In other words, by using horizontal branching air, the blown air mixes only in the upper part of the living space, providing a heating effect without making the human body feel cold.

When the temperature of the air outlet becomes higher, the air blows in the direction previously detected and memorized. For example, if the detected and memorized position is in the center of the room and at the rear, the air blows out horizontally, blowing warm air directly to the human body. It can increase the heating effect.

At this time, the walls have already been warmed to some extent, so there are no areas of low humidity in the living room.

In the above embodiment, a case is described in which concentrated blowing is performed when the blowing temperature is high, and divided blowing is performed when the blowing temperature is different, but the reverse may be used. Further, although the above embodiment has been described for the heating operation, the same effect can be obtained during the cooling operation. In addition, since the position of the remote control can be detected, the wind direction can be changed freely without having to set the wind direction in advance.No matter where the main unit is installed in the room, the wind will automatically be directed in the desired direction. Can be done.

Dandruff Consequences of the Invention As is clear from the description of the above embodiments, the present invention allows the desired wind direction and position to be set instantaneously by detecting the position of the remote controller, and is stored in memory. When the temperature reaches the desired temperature, the horizontal branch outlet can automatically direct hot or cold air in the desired direction. Therefore, the direction of the wind can be concentrated at any one point or divided, so that the feeling of heating and cooling can be enhanced and comfort can be improved. Furthermore, since the remote control position can be detected, the wind direction can be changed freely without setting the desired wind direction in advance, improving operability.
