Abstract

PURPOSE:To prevent rapid decrease of a room temperature during stop of blast, by a method wherein the direction of a blast from an air conditioner forms a down direction flow or a direction branched into the left and the right and compressor capacity id brought into an increased state or forms a downward direction and a concentrated direction and compressor capacity is brought into a decreased state, and each state is held for a specified time length. CONSTITUTION:When a given time reaches after a point of time when an air conditioner performs specified motion, the direction of blast from an air condition forms a downward and a direction banched into the left and the right and compressor capacity is brought into an increased state or forms a downward and concentrated direction and compressor capacity is brought into a decreased state, and each state is held for a specified time. Namely, when a direction of blast during heating forms a downward direction and a direction branched into the left and the right and compressor capacity is brought into an increased state, the wall of a room to be air-conditioned is warmed, and even when an air conditioner is stopped, the wall prevents rapid decrease of a room temperature. When a blow-off direction of warm air forms a downward direction and a concentrated blow-off direction and compressor capacity is brought into a decreased state, air is blown directly against a human body to increase heating effect.

Description

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

In addition, the left and right deflection vanes and the top and bottom deflection vanes have a constant 'TF'j
There is a device that allows you to swing in the light. (U.S. Patent No. 32
57931 Specification M) This second conventional example is shown in FIGS. 11 and 12.

In the same figure, the upper part of the air outlet 1010 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 via a connecting bar 105a and a lever arm 106a.

7cK read: rt. In addition, each bellows 107a,
107b1107cK are heaters 108a and 10, respectively.
8b and 108c are wound.

Reference numeral 109 denotes a microswitch that controls energization If11 of the heaters 108a, 108b, and 108c.

In the above p, I, l) configuration, the heater 108a1108
By energizing b1108c, the bellows 107
a, 107b, and 107c extend, and this bellows 107b
The expansion of the heater 108 activates the microswitch.
The power supply to a, 108b, and 108c is stopped. As a result, bellows 107a.

107b and 107c are cooled and contracted.

By repeating this motion, 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 are not sufficiently warmed due to heat conduction with the outside air and the heat capacity of the walls themselves.

For this reason, when the humidity of the air exceeds a predetermined level and the air conditioner is stopped by the temperature controller, the wall creates a negative IL space.7? The temperature is rapidly dropping to low F.

In addition, if hot air is constantly deflected between the living space and the wall to solve the above problem, the wind speed of humidity 1 that hits the human body will fluctuate widely, causing discomfort to the human body due to the fluctuation in wind speed. There was a problem.

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

In addition, although the second conventional tq'l configuration is capable of deflecting airflow in the horizontal direction, it deflects the air to the left and right at regular intervals, which may not be able to sufficiently heat the wall surface. Although the walls could be heated sufficiently, there was a problem in that the warm air did not reach the living space sufficiently, resulting in a loss of comfort.

In addition, in the second conventional configuration, the hot air is constantly deflected to the left and right,
Since the speed of the warm air hitting the human body fluctuates widely, there is a problem in that the wind speed Ω 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 a variable compressor and an indoor heat exchanger therein, and an indoor unit provided in this indoor unit and equipped with the indoor heat exchanger. An air outlet that blows out the air that has passed through the air outlet; a vertical deflection blade that deflects the air that is blown out from the air outlet in the vertical direction; left and right deflection blades that branch and deflect in different directions;
A control device for controlling the drive of the vertical deflection vanes and the left and right deflection vanes and the capacity of the variable capacity compressor is provided, and this 15 control device and a drive for independently deflecting the vertical deflection vanes and the left and right deflection vanes are provided. and an output means for outputting an output to the driving means when the elapsed time since the time when the variable capacity compressor, the driving means of the variable capacity compressor, and the air conditioner performed a certain operation reaches a predetermined value, When the time reaches a predetermined value, the air blowing direction is set such that the air blowing direction is the F direction and the direction branched to the left and right until the elapsed time reaches the predetermined value, and the capacity of the variable capacity compressor is large. For example, when the air blowing direction is downward and concentrated, the capacity of the variable capacity compressor is changed to a lower capacity setting and held for a certain period of time, and when the air blowing direction is downward and concentrated, the capacity of the variable capacity compressor is changed to a lower setting. If the capacity of the compressor is set to be low, set the capacity of the variable capacity compressor to be large so that the air blowing direction is downward and branched to the left and right, and hold this for a certain period of time to increase the output of the output means. This is driven repeatedly.

Effect With the above configuration, the air conditioner air deflection device of the present invention changes the air blowing direction of the air conditioner downward when the elapsed time from when the air conditioner performs a certain operation reaches a predetermined value. Either the direction is branched to the left and right and the capacity of the compressor is high, or the direction of air is concentrated downward and the capacity of the compressor is low, and each condition is maintained for a certain period of time.

When the airflow direction during heating is downward and branched to the left and right, and the capacity is high, the walls of the air-conditioned room become damp.

In addition, in this state, the compressor has a large capacity, so the temperature of the hot air becomes high, making it easy for the walls to become warm.

When the airflow direction during heating is concentrated downward and the compressor capacity is low, the hot air directly hits the human body in the store owner's space, resulting in a feeling of heating.

In addition, since each state is maintained for a certain period of time, fluctuations in the wind speed of the wet air hitting the human body are reduced.

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 deflects the wind direction vertically by a fang effect has a shaft 2 in its longitudinal direction, and this shaft 2 is connected to an intermediate motor (stepping motor) a. Further, the left and right deflection blades that horizontally deflect the blown air by the coering 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
Left motor (stepping motor) 9 via blade lever arm 6a, rod 7a1 and morke lever arm 8a.
a, and the right deflection blade 5b is connected to the blade lever arm 6.
b. Rod 7b1 is connected to a right motor (stepping motor) 9b via a morking lever arm 8b. Here, the left deflection blade 5a is slightly curved so that its center is on the left side of the left deflection blade 5a, and the right deflection blade sb
u It is slightly curved so that its center is on the right side of the right deflection blade 5b. That is, the air outlet 12 described later
This is to cause the above-mentioned coring phenomenon to occur on both side portions 13a and 13b of the windshield, thereby deflecting the wind direction. Since the Coing 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 one motor for driving the left and right deflection blades, or K is a gear or a clutch, 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 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 even more delicate control of the wind direction, the structure may be divided into even smaller sections, or conversely, the structure may be divided into even smaller sections.
As shown in FIG. 2, they may be connected by a single connecting bar 4. In addition, the left deflection blade 5a and the right deflection blade 5b are curved in order to not only deflect the wind direction by the coring effect but also to enhance the concentration and separation effect that is the object of the present invention.
If the coang effect is not taken into account, the shape may be a planar shape that is not curved, or even the direction of the curved surface may be 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 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 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, the refrigeration cycle of the wooden embodiment is shown in FIG.

In the figure, a rotation speed oT variable 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, the refrigerant is supplied to the variable speed compressor 17 during heating operation.
, flows through the four-way valve 18, indoor heat exchanger 15, capillary tube 19, and outdoor heat exchanger 20, and during cooling operation, the rotating & variable pressure X? It flows directly through 11: 4 machines 17, 4-way valve 18, outdoor heat exchanger 20, capillary 19, and indoor heat exchanger 15.

Next, FIG. 7 shows a mold section circuit diagram of the embodiment.

The microcomputer 722 includes a storage section 23 that stores a preset time, and a drive signal generation means 24 that generates an appropriate output (No. 3) from a comparison between the set value stored in this storage section 23 and an input value. have.

A timer 21, which is a time detection means, is connected to the input side of this microcomputer, and is driven via a buffer 26 that supplies pulse output to each motor 3.9a, 9b and the motor 17a of the variable rotation speed compressor 17. The means are a middle motor 3 and a left motor 9a.

Right motor 9b, variable rotation speed king, compressor 17 motor 1
7a is connected. 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 FIG. 7, the timer 21 shown in FIG. The drive signal generation means 24 of FIG. 7 corresponds to the set time storage means of FIG. 3, the drive signal generation means 24 of FIG. 7 corresponds to the drive signal generation means of FIG. 3, and the motors 3.9a of FIG.

9b and 17a correspond to the driving means in FIG.

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

T is the elapsed time from the start of operation of the variable speed compressor 17, and T1, T2, T3, and Tn-T (n-1) are the 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 the rotation speed of the motor of the variable rotation speed compressor 17 is Raise the height and stop. Here, rotating the middle motor 3 to the left moves the upper and lower deflection blades 1 to the lower position, and rotating the left motor 9a to the right moves the left deflection blade 5a to the left side.
Rotating the right motor 9b to the left indicates driving the right deflection blade 5b to the right. In other words, the temperature of the blown air is in a state where the temperature of the downward branched blown warm air is higher than normal, as shown in FIG. 9. At this time, it is not known what state the upper and lower deflection blades 1, left deflection blade 5a, and right deflection blade 5b are in, but they are sure to rotate to the above positions after each motor 9a19b19c is driven. That is, when the deflection is already at the same position as the position after driving in the initial state, the motor is not rotated by a load resistance such as a stomper, or the motor is idled. After each motor 9a, 9b, 9c has rotated (before or during rotation as required), the elapsed time and the set time are compared again.

Next, if the second set time T2 or less is reached, the middle motor 3 is rotated counterclockwise, the left motor 9a is rotated counterclockwise, and the right motor 9b is rotated clockwise and stopped. Motor 17
Lower the rotation speed of a. That is, the blown air is concentrated downward and the temperature of the blown hot air becomes normal, as shown in FIG. 9.

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 the time is shorter than the set time, 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 stopped. 1
Increase the number of elbows. That is, the blown air is concentrated downward and the temperature of the blown hot air is higher than normal, as shown in FIG. 10. Further, sufficient time is provided between each of the set times T1, T2, and Tn, and each motor other than the motor 17a of the variable rotation speed compressor 17 has a sufficient stop time after rotation.

Each motor repeatedly performs the above operation.

The effect when such an operation is performed during heating operation will be explained. First, the walls of the room are warmed by blowing warm air with a higher temperature than usual downward, so 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 at the normal temperature is blown out in a concentrated downward direction, the heating effect can be enhanced by directly applying 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 it does not cause discomfort to the human body.

While the warm air is being blown out in a downward diversion, heating is performed from around the 1st floor, and while the concentrated downward blown air is being blown out to warm the wall and its surroundings, the temperature is locally reduced by the cooled wall surface. The heating effect is performed from the center of the room without creating a low space. Therefore, by repeatedly heating the store from these two directions while maintaining it for a certain period of time, it is possible to make the temperature distribution in the store owner's space uniform.

Effects of the Invention As is clear from the description of the above embodiments, the Kokuhatsu 811 warms the walls of the room by blowing hot air downward, and even if the air conditioner is stopped by the temperature controller, the walls will not disturb the air. Room temperature does not drop rapidly. 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 warm air is
Although the air is repeatedly blown out in each direction, it is maintained for a certain period of time when blown out in each direction, so there is less discomfort to the human body due to rapid changes in wind speed, and the compressor's capacity is high when hot air is blown out in a downward direction. Since the temperature of the hot air becomes high, walls that are far away from the air conditioner can be sufficiently warmed.

When hot air is blown downward, the capacity of the compressor is low and the temperature of the hot air is normal, but by directly blowing hot air to the human body, comfortable heating can be achieved.

As a result, economical and comfortable heating can be achieved.
