Abstract

PURPOSE:To contrive the improvements of temperature distribution and comfortable property by controlling the deflecting direction of the blow-off air of an air-conditioning machine with a give period. CONSTITUTION:This air-conditioning machine increases the revolving number of a compressor 17 during some time of elapse from the starting of the operation thereof, drives a deflecting vane 1 downwardly, the deflecting vane 5a rightwardly and the deflecting vane 5b leftwardly to concentrate the blow-off air thereof downwardly. Subsequently, the same machine decreases the revolving number of the compressor 17 and drives the vanes 5a, 5b into the opposite direction to distribute the blow-off air downwardly. Warm-air repeats the blow- off thereof toward these two directions, however, the directions are kept for a given period of time upon being blown off toward respective directions. According to this method, a sudden fluctuation in the airflow directions with respect to a human body is small, therefore, uncomfortable feeling will never be provided to the human body. As a result, comfortable heating may be realized.

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 a horizontal direction and a vertical direction, and blows out in the horizontal direction when the blow-out temperature is lower than the set temperature, and 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 comfort in a large living space, there is a device that swings the left and right deflection blades and the top and bottom deflection blades at a constant period. (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 air outlet 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 a bellows 107 via a coupling device 105a and a lever arm 106a.
connected to a. Also, left and right deflection blades 103, 104
are connected to bellows 107b, 1 via coupling devices 105b, 105c and lever arms 106b, 108c, respectively.
Connected to 07c. Also, each bellows 107a, 1
Heaters 108a and 108 are installed in 07b and 107c, respectively.
b, 108c are wound. 109 is a heater 108a
, 108b, and 108c.

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

Bellows 107a by energizing 108c.

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, 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 first conventional configuration described above, deflection control is only possible in the vertical direction.For example, the cold air during heating can be prevented from directly hitting the human body, but it is possible to control the deflection in one direction (
As the air blows out in the forward direction, the movement of air within the living space becomes large, and the temperature feels lower than the actual room temperature.

In addition, since the r-direction air outlet directly hits the human body, the temperature of the air outlet must be raised sufficiently, and it takes a long time from the start of operation to the downward air outlet, resulting in the problem that the heating start-up is slow. .

In addition, in the second conventional configuration, although it is possible to deflect the airflow in the horizontal direction, the airflow swings regardless of the airflow temperature, so it is not possible to shorten the start-up time or perform efficient heating, especially during heating operation. There was a problem.

An object of the present invention is to improve the comfort of a living space using an air conditioner, particularly to improve the comfort of heating operation.

Means for Solving the Problems In order to solve the above problems, the present invention compresses a refrigerant,
A variable rotation speed compressor that constitutes a refrigeration cycle together with an indoor heat exchanger and an outdoor heat exchanger; an indoor unit that includes the heat exchanger and the blower; and an indoor main exchanger that is installed in the indoor unit. An air outlet that blows out the air that has passed through it, a vertical deflection blade that vertically deflects the air that is blown out from this 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 described in 111. left and right deflection vanes that branch and deflect in left and right directions, vertical drive means and left and right drive means that reciprocate the vertical and left deflection vanes, respectively, and a compressor that changes the rotation speed of the variable rotation speed compressor. a driving means, an elapsed time detecting means for detecting the elapsed time since the air conditioner was started up, and a set time storage means for storing a preset time;
an output means for outputting an output to each of the driving means when the elapsed time reaches a set value; The direction is concentrated downward and maintained for a certain period of time, and when the elapsed time reaches the set value, the rotation speed of the variable speed compressor is lowered and the direction of air is diverted downward and maintained for a certain period of time. After that, the blowing direction is repeatedly deflected in the downward concentration direction and the F direction branch direction.

Effect By using the above means, the method for deflecting the wind direction of an air conditioner of the present invention lowers the rotation speed of the variable rotation speed compressor and changes the downward concentrated blowout to the downward divided blowout when the elapsed time reaches a certain set time. Therefore, when the heating capacity is high, local heating can be performed and heating operation can be performed.

Also, when the elapsed time reaches a certain set time, the temperature of the air outlet is also high, and by lowering the rotation speed of the variable rotation compressor, the temperature of the air outlet is suppressed and heating is performed from the surrounding area at the bottom of the living space. I can do it.

Furthermore, since the direction of the wind is repeatedly deflected at a certain period, it is possible to obtain a fluctuating effect on the blown air, thereby improving temperature distribution and comfort.

Example Hereinafter, the present invention will be explained using 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 performs vertical wind direction deflection by the Coanda effect has a shaft 2 in its longitudinal direction, and this shaft 2 is connected to an intermediate motor (stepping motor) 3. 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 4o and a right deflection vane 5b connected to a coupler 4b. And the left deflection blade 5a is
The left motor (stepping motor) 9 is connected via the blade lever arm 6a, rod 7a, and motor lever arm 8a.
a, and the right deflection blade 5b is connected to the blade lever arm 6.
It is connected to a right motor (stepping motor) 9b via a rod 7b and a motor lever arm 8b. Here, the left deflection blade 5& is slightly curved so as to have its center on the left side of the left deflection blade 5a, and the right deflection blade 5b
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 Coanda phenomenon to occur on both sides 13a and 13b, thereby deflecting 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 possible to use a shape memory alloy spring that changes depending on the ambient temperature instead of the motor, and in this case, the alloy itself has the temperature detection means and set temperature storage means, which are essential requirements of the present invention. Become. 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 left deflection blade 5a and the right deflection blade 5b are curved in order to not only deflect the wind direction by the Coanda effect but also to enhance the concentration and splitting effect which is the object of the present invention. If this is not taken into account, it may be a planar shape that is not curved, or it may even have a shape with the round directions 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 same figure, the front of the indoor unit 10 has a suction port 11 for sucking indoor air.
An air outlet 12 having upper and lower deflection blades 1 and left and right deflection blades 5a and 5b is provided below the suction port 11. Both side portions 13a and 13b 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 variable rotation speed 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 supplied to the variable speed compressor 17.
, the four-way valve 18, the indoor heat exchanger 15, the capillary tube 19, and the outdoor heat exchanger 20 in this order, and during cooling operation,
Variable rotation speed compressor 17, four-way valve 18, outdoor heat exchanger 2
0, the 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 2a 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 the input value. There is.

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

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

T is the elapsed time from the start of compressor 17 operation, and T4
．． T2 """Tn-T(n-1) is the setting time.

When this elapsed time T is shorter than the first set time T1, the rotation speed of the variable rotation speed compressor 7 is increased, and 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. Here, rotating the middle motor a to the left moves the upper and lower deflection blades 1 to the lower position, rotating the left motor 9a to the left moves the left deflection blade 5a to the right, and rotating the right motor 9b to the right moves the right deflection blade 5b. indicates that it is driven to the left. In other words, the blown air is concentrated downward and the 9th
The result will be as shown in the figure. At this time, it is not known what initial state the upper and lower deflection blades 1, left deflection blade 5a, and right deflection blade 5b are in, but each motor 3.9a, 9b
, 17 are rotated to the above-mentioned 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 using a no-load resistance such as a stopper, or the motor is allowed to rotate idly. After each motor 3, 9a, 9b 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, the rotation speed of the variable rotation speed compressor 7 is lowered, 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. do. That is, the blown air becomes a downward branch as shown in FIG. Also, T1. Sufficient intervals are provided between each set time from T2 to Tn, and each motor other than the 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. By increasing the rotation speed of the variable rotation speed compressor and directing the air to the bottom, the maximum capacity can be achieved with the least ventilation resistance and the start-up characteristics can be improved. Also, change the hot air blowing direction to a downward branch blowout.
By lowering the rotation speed of the variable speed compressor,
Heating can be performed from the periphery of the living space with little input. The hot air is repeatedly blown out in the two directions mentioned above, but because it is held for a certain period of time when blown out in each direction,
There are few rapid changes in wind direction relative to the human body, and there is no discomfort to the human body.

Effects of the Invention As is clear from the description of the above embodiments, the present invention achieves the maximum capacity with the least ventilation resistance by increasing the rotation speed of the variable rotation speed compressor and by controlling the airflow to be concentrated downward. This improves the rise characteristics. Furthermore, by setting the hot air blowing direction to a downward branch blowing direction and lowering the rotational speed of the variable rotational speed compressor, heating can be performed from the periphery of the living space with less input. For hot air, see 2 above.
The air blows in different directions repeatedly, but because the blow is held for a certain period of time in each direction, there is little rapid change in wind direction relative to the human body, and there is no discomfort to the human body.

As a result, comfortable heating can be achieved.
