CONSTITUTION:When the temperature of blow-off air which is detected by a thermistor 21 is lower than a set temperature, a revolving number variable compressor 17 is driven at large rotating number, a central motor 3 is turned right to drive an upper and lower deflecting vane 1 to horizontal position, a left motor 9a is turned right to drive a left deflecting vane 5a to the left side and a right motor 9b is turned left to drive a right deflecting vane 5b to the right side thereof. Accordingly, blow-off sir becomes horizontally branched airflow. When the temperature of the thermistor 21 is higher than the set temperature, the compressor 17 is driven at low revolving number, the central motor 3 is turned left, the left motor 9b is turned left and stopped, whereby the blow-off air becomes downward branched airflow.

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.

Conventional Technology Until now, the method of blowing air conditioners in one direction has been used to improve the suitability of living spaces.
Various devices have been considered.

For example, if the air outlet is horizontal and right-hand direction 3! There is a device that blows out horizontally when the blowing temperature is lower than the set temperature, and blows vertically when it is higher than the set temperature. (Japanese Patent Publication No. 10813/1983) In other words, the configuration of this first conventional example is the so-called call 1
! It prevents drafts and can increase the temperature and temperature.

Maf: Furthermore, it improves the comfort in a wide living space. On the other hand, there is a device that swings the left and right deflection blades and the top and bottom 9111 direction blades at a constant circumference of 1υ1. 3 (
(U.S. Pat. No. 3,257,931) This second conventional example is shown in FIGS. 11 and 12. Deflecting upper and lower deflection blades 102
, left and right deflection vanes 103 and 104 are provided for deflecting the blown air 7t' in the horizontal direction. The upper and lower deflection blades 102 are connected to the bellows 10 via a coupling FR 105a and a lever arm 106a. The matco left and right deflection blades 103 and 104 are connected to the coupling machine 105b, respectively.

8b and 108c are wound. 109) Knee<p
This is a microswitch that controls the current flow of 108a, 108b, and 108c by 6A+.

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

is cooled and contracted, and by repeating this operation f) the effect of fluctuating blown air can be obtained.

Problems to be Solved by the Invention However, in the first conventional configuration, it is only possible to control the deflection in the vertical direction, so that, for example, cold air during heating can be prevented from directly hitting the human body. Since the air blows out in one direction (+3iJ direction), the movement of air in the living space becomes large, and the temperature feels lower than the actual room temperature, and the downward air blows directly into the human body. : Please note that the blowing temperature must be sufficiently low, and the time from the start of operation to the downward blowing must be long enough. L, what was the problem with the heating q7t) slowing down?

In the second conventional configuration, the air outlet 1 can be deflected in the horizontal direction, but it is independent of the air outlet temperature; ) We combined the problems of shortening the time and performing efficient heating.

The object of the invention is to improve the comfort level of a living space using an air cooling device, and to improve the comfort level at the start of heating operation.

The present invention compresses a refrigerant and improves the rotation speed of an indoor heat exchanger, which together with the indoor heat exchanger constitutes a refrigeration cycle. A variable compressor, an indoor unit having the indoor heat exchanger inside, an air outlet provided in this indoor unit that blows out the air that has passed through the indoor heat exchanger, and an air outlet that blows out the air that has passed through the indoor heat exchanger. Upper and lower 11 directing vanes that deflect in the vertical direction, and left and right deflectors that are independently provided on the left and right f of the Suita exit described in 1J and that branch and control the air blown out from the Suita exit described in 11 in the left and right directions. LF drive means and left and right drive means for reciprocating the direction blade limit and left and right deflection blades, respectively, and compressed image drive means for changing the rotation speed of the variable rotation speed compressor. and temperature of air from the air outlet; i
f: is when the room temperature reaches a predetermined value.
An input/output output means is provided, and the air blowing temperature increases the rotation speed of the variable rotation speed compressor before the room temperature reaches a predetermined value. With this, the blowing direction is horizontal or upward and branched to the left and right, and if the blowing temperature is the rotation of the deformed compressor, the air blowing temperature is determined by the number of times the room temperature reaches a predetermined shift. When the number is lowered, the air blowing direction is branched to the left and right in the F direction, and the two directions are (C and E).

Effect: By the above-mentioned means, the wind direction deflection force of the air conditioning reed of the present invention can be adjusted to a certain set temperature IW, which is either the outlet temperature or the room temperature. −
When the rotational speed of the TiJ modified compressor is lowered, the horizontal branch outlet becomes a downward branch outlet, so when the outlet temperature is low during one-month operation,
This is done by increasing the rotation speed of the r+J barley compressor to promote the rise in the temperature of the air outlet, and also to combine the air in the upper part of the living space, heating the room without making you feel cold. can be done. Furthermore, when the temperature of the air outlet is high, by lowering the rotation speed of the variable speed compressor, heating is performed from the periphery of the lower part of the living space while suppressing the temperature of the air outlet, improving temperature distribution,
This improves comfort and enables efficient heating with low input.

EXAMPLE Hereinafter, a method for deflecting the wind direction of an air conditioner and an apparatus equipped with the same method according to an example of the present invention will be described with reference to the drawings.

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

As shown in the figure, a) Slightly 1"L in the direction of the balloon.
The vertical deflection blade 1 which is bent and deflects the wind direction upward and downward by the Coanda effect has a shaft 2jJ) in its elongated direction,
This shaft 2 is connected to a medium motor (stepping motor) 3. The left and right deflection vanes that deflect the blown air in the horizontal direction by the Coanda effect are connected by the connecting Q4a.
The left deflection vane 5a is connected to the left deflection vane 5a connected to the coupling machine 4b, and the left deflection vane 5a is connected to the coupling machine 4b. a. Connected to the left motor (stepping motor) 9a via the motor lever arm 8a I~; The right deflection blade 5b is connected to the blade lever arm 6b, the rod 7b,
It is connected to a right motor (steel, knobbing motor) 9b via a motor lever arm 8b. Here left + tni
The deflecting blade 5a is slightly curved so that its center is to the left of this left deflecting blade 5a, and the right deflecting blade 5b is slightly curved to have its center to the right of this right deflecting blade 5b. ing. Sainawa T, air outlet 120 described later
The Coanda phenomenon described in []11 is generated between the side portions 13a and 13b, and the wind direction is deflected. Since the Coanda effect is a well-known technique from the prior art, its explanation will be omitted.

In this embodiment, the drive means for the deflecting blades is composed of the middle motor 3, the left motor 9a, and the base motor 9b, but it is also possible to use a single motor for driving the left and right deflecting blades, and it is also possible to use gears or It is also possible to control the upper and lower deflection vanes 1 and the left and right deflection vanes with a single motor by using a switching means such as a clutch. Further, the motor is not limited to a stepping motor, but may be an induction motor or the like.

It is also possible to use a spring made of a shape memory alloy that changes depending on the ambient temperature instead of the motor, and in this case, the alloy 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 that the flow dividing operation that is the object of the present invention can be easily performed, and the wind direction can be controlled independently of each other. In order to perform delicate wind direction control, 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. Matko left deflection blade 5
a. The right deflection blade 5b is bent to deflect the wind direction by the Coanda effect, and is also shaped to enhance the shunting effect that is the objective of the present invention, taking into account the Coanda effect described in IJ. If not, even if it is not curved, the plane f
(In terms of shape, even the direction of each side is reversed)
It may be small or small.

Next, FIG. 3 shows a perspective view of the indoor unit 10 equipped with the wind direction deflection method shown in FIG. 1 and equipped with the device.

In the same figure, there is an inlet 11 on the front of the indoor room 10 that sucks indoor air, and this inlet [-111
At the bottom thereof are a vertical deflection blade 1 and a left and right deflection blade 5a.

5b is provided with an air outlet 12. Both sides 13a and 13b of this air outlet 12 have a curved surface that gradually expands outward to deflect the wind direction by the Coanda effect as described above, and i. (As mentioned above, the lower surface portion 14 also has a curved surface that gradually expands in order to control the wind direction due to the Coanda effect.

This indoor unit 10 is sawed off (a whistle diagram is shown in FIG. 4). An indoor heat exchanger 15 is placed at a position 11q opposite to the suction port 11, and a blower 16 is provided in the ventilation path from the indoor heat exchanger 15 to the air outlet 12. The rotation speed is shown in Figure 5.
A modified compression rock 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, the refrigerant is supplied to the variable rotation speed compressor 1 during heating operation.
7. Four-way valve 18. Indoor heat exchanger 15. Capillary tube 19. The flow goes through the outdoor heat exchanger 20 in this order, and during cooling operation, the rotation speed variable compressor 17° four-way valve 18. Outdoor heat exchanger 20. capillary chew 719. The heat flows through the indoor heat exchanger 15 in this order.

Further, 21 is a temperature detector that detects the suction temperature 1y,
This is an example of a temperature detection means for detecting room temperature, and the room temperature detection location is not limited to the vicinity of the suction.

FIG. 6 shows a circuit diagram of the main parts of this embodiment. The microcomputer 22 includes a storage section 23 that stores a preset temperature, 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 a human power value. There is. A thermistor 21 serving as temperature detection means is connected to the input side of this microcomputer via a conoparator 25, and a variable rotation speed compressor 17. Each motor 3.9a, 9b is connected via a buffer 26 which supplies the pulse output to the rotational speed variable compressor 17, which is a driving means, the middle motor 3, the left motor 9a, and the right motor 9b. Here, 27 is a bias resistor,
28 is a scan resistor 13 Next, the operation of this embodiment is shown in FIG. This figure is a flowchart during heating operation.

The blowout temperature t is detected by the thermistor 21, and t is the temperature, and tl is the set temperature. When this blowing temperature t is lower than the set temperature t1, the rotating modified compressor 17
is set to a high rotation speed, the middle motor 3 is rotated at G, the left motor 9a 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 vertical blade 1 to the horizontal position (upward position if necessary), and rotating the left motor 9a to the right L[]1 means moving the left deflecting blade 5a to the left side. , rotating the right motor 9b to the left moves the right deflection blade 5b to the right side i.
This indicates that this is driven. In other words, the blown air becomes horizontally divided as shown in FIG. At this time, it is difficult to know what initial state the lower deflection vane 1, left deflection vane 5a, and right deflection vane 5b are in, but after driving each motor 9a, 9b, and 9c, they are always in the above state. It rotates into position. In the initial state, the motor is at the same position as after being driven; if it is already deflected, the motor is prevented from rotating by a load resistance such as a stopper, or the motor is allowed to rotate idly. And each motor 9a.9
After rotation of parts b and 9c (before or during rotation as required), the temperature of the thermistor 21 and the set temperature are compared again.

Next, if the temperature t of the thermistor 21 is lower than the set temperature t1, the variable speed compressor 17 is set to a lower speed, the middle motor 3 is rotated to the left, the left motor 9a is rotated to the right, and the right motor 9b is turned to a lower speed. Rotate to the left and stop.

The air blown out from the CC straw is diverted downward (as shown in Figure 9). When the flow is already in the horizontal branching state as shown in FIG. 8 before this operation, only the upper and lower deflection blades 1 are substantially deflected.

Due to the lack of the action described in L, the cold air, which is not pleasant to the body, becomes a horizontal branch blowout so that it does not directly hit the adults (the temperature of the second blowout increases rapidly, and the blowout temperature becomes warmer). If it is installed, the airflow will be diverted downward so that it indirectly hits the human body, and the temperature rise of the airflow will be suppressed as much as possible, resulting in efficient operation with a low input of 4C.

The effect of such an operation at the start of heating operation will be explained. First of all, the air outlet temperature is low immediately after the heating operation starts.
(7) I don't like direct contact with the human body.In addition, even if the air does not directly contact the human body, if the air in the living space moves a lot, it will feel like the temperature is lower than the actual room temperature. It is preferable that the movement be small.In other words, by using a horizontal branch blowout, the blown air will mix at the end of the living space, making the human body feel cold.
<While performing a heating effect, the rotational speed of the rotary Keiji modified compressor is increased to promote a rise in the blowout temperature, resulting in a faster rise in temperature.

Next, when the temperature of the air outlet becomes low, the air outlet becomes a branch air outlet in the F direction, so the heating effect is performed from the periphery of the living space. In other words, even in this case, it is possible to make the human body feel cold and perform heating.43 Furthermore, by tightening the wall surface, the start-up time can be shortened. Uniform rotation speed aJ
By lowering the rotation speed of the modified compressor, it is possible to suppress the rise in outlet temperature and achieve efficient heating with less input.

Effects of the Invention As is clear from the explanation of the above-mentioned practical example, the present invention has the advantage that when the blowout temperature reaches a certain set temperature, the rotation speed of the variable speed compressor is changed to 5. By lowering the number of airflows and changing from a horizontal branching outlet to a downward branching outlet, the temperature of the outlet is promoted and the temperature of the outlet is lowered.In some cases, the air mixing effect is performed only in the upper part of the living space. Sunao)
At this time, it is possible to improve the mixing effect of air only in the 1 m k area of the living room by using both horizontal and branch air blowing, and prevent large air movement in the lower part of the living space. Because you can do this, you won't physically feel the cold.

Furthermore, when the blowout temperature is high, the blowout becomes a downward branch flow, so around the lower part of the living space, the rope r, +1g +T
It's going to change from n to iI'I□l'L! If you can plan out the uniformity of the division, it will be 4! :Mo;ko balloon temperature 11

<i! I can go to work/i. If the air is blowing downward, the air will blow directly into the human body; -7 air will be hot, so the blowing temperature must be high enough before the downward blowing can be carried out. However, it is possible to create a downward blowout at a certain level of temperature and rise, which is a branch blowoff, and efficiently increase the heating effect S'Z k, '

Furthermore, even if there is a change in room temperature Cζ, when performing 1-4rJ1 cultivation, even if there is a change in room temperature Cζ, equally effective heating can be achieved.
