Abstract

PURPOSE:To improve the comfortableness of a living space during heating operation by a method wherein an up-and-down deflecting vane is driven so that the direction of blow-off air is directed downward and the blow-off air is concentrated into one direction while a fan is driven at high speed when blow-off air temperature has arrived at a predetermined value. CONSTITUTION:When a blow-of air temperature detected by a thermistor 21 is lower than a set temperature, a fan 16 is driven in a low speed, a central motor 3 is turned right to drive an up-and-down deflecting vane 1 to horizontal position, a left motor 9a is turned right to drive a left deflacting vane 5a to left side and a right motor 9b is turned left to drive a right deflecting vane 5b to the right side. In this case, blow-off air is branched horizontally and the amount thereof is reduced. When the blow-off air temperature detected by the thermistor 21 is higher than the set temperature, the central motor 3 is turned left, the left motor 9a is turned left, the right motor 9b is turned right and is stopped, whereby the blow-of air is concentrated into the lower part of a room and the amount of airflow is increased to a large amount.

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) 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. (U.S. Pat. No. 3,257.931) This second conventional example is shown in FIGS. 11 and 12.

In the same figure, the riiJ surface part V of Suitaguchi 101 is

2. Left and right deflection vanes 1 that deflect the blown air in the horizontal direction
03 and 104 are provided. - The lower vane 102 is connected to the bellows 107a via a coupling Em 105a lever arm 106a. Further, the left and right deflection blades 103 and 104 are connected to the coupling machines 105b and 1, respectively.

Heaters 108a and 10 are installed in 107b and 107c, respectively.
8b and 108c are wound.

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

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

By energizing 108c, Siberose 107a
, 107b, 107c are expanded, and the expansion of the bellows 107b operates the microswitch to activate the heater 108a.
, 108b, and 108c. the result,
Bellows 107a.

107b and 107c are reduced by 6 and contracted.

By repeating this action, you can obtain the effect of fluctuating the blown air.

Problems to be Solved by the Invention However, in the first conventional configuration described above, deflection control is only possible in the vertical direction.
Because the air blows out in the forward direction, the movement of air within the living space increases.

Physically, the temperature feels lower than the actual room temperature.

In addition, the downward blowout has the problem that it does not give a feeling of heating compared to other heating appliances such as gas appliances because the air blows out into the area surrounding the lower area.

Further, in the second conventional configuration, although the airflow can be deflected in the horizontal direction, the airflow swings regardless of the airflow temperature, so there is a problem in that efficient heating cannot be performed.

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

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, an air blower, and the indoor heat exchanger that constitute a four-freezing cycle together with an indoor heat exchanger and an outdoor heat exchanger; an air outlet for blowing out air; a vertical deflection blade for vertically deflecting the air blown from the air outlet; a left and right deflection vane that branches and deflects; a drive means that independently drives the lower deflection vane and the left and right deflection vanes to deflect;
It has a temperature detecting means for detecting the blowing temperature and a set temperature storing means for storing a preset temperature, and when the air blowing out from the blowing outlet is branched to the left and right and the rotational speed of the blower is low, When the temperature of the blown air reaches a predetermined value, the upper and lower deflection blades are driven so that the blowing direction is downward, the blown air is concentrated in one direction, and the rotation speed of the blower is increased. It is something.

Operation-1- According to the means described above, the air direction deflection device of Kazuki Oka of the present invention is capable of blowing out downwardly from the horizontal branching blowout (~) when the blowout temperature or the room temperature reaches a certain set temperature, and the rotational speed of the blower changes. Since the speed changes from low to high speed, when the air outlet temperature is low during heating operation, air mixing is performed only in the living space area.

Heating can be performed without physically feeling cold. Furthermore, when the temperature of the air outlet is high, the heating is concentrated and directly performed from the lower part of the living space, so that the feeling of heating to the human body can be improved.

Example Below, the wind direction 1 (1
The i-direction device 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,
The lower pan direction blade 1, which performs vertical wind direction deflection by the Coanda effect, has a shaft 2 in its longitudinal direction fTL, and this shaft 2 is connected to a middle motor (stepping motor) 3. Further, the left and right deflection vanes which 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 1i4b. The left deflection blade 5a includes a blade lever arm 6a, a rod 7a,
It is connected to the left motor (stepping motor) 9a via the motor lever arm 8a, and the right deflection blade 5b is connected to the right motor (stepping motor) 9b via the single blade lever arm 6b, rod 7b, and motor lever arm 8b. Connected. Here, the left deflection blade 5a is this left deflection blade 5.
Slightly curved so that the center is on the left side of a,
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 above-mentioned Coanda phenomenon is generated on both sides 13a and 13b of the air outlet 120, which will be described later, to deflect the wind direction. Since the Coanda effect is a well-known technique, its explanation will be omitted.

In this embodiment, the instep motor 3 and the left motor 9a.

Although the right motor 9b constitutes the driving means, it is also possible to use a single motor for driving the left and right deflection blades, and furthermore, by using a switching means such as a gear or a clutch, the upper and lower deflection blades 1 and the left and right deflection blades can be switched. It is also possible to control the motor 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, instead of a motor, it is also possible to use a spring made of a shape memory alloy that changes depending on the surroundings, and in this case, the alloy itself has the temperature detection means and set temperature storage means that are essential to 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 because the purpose of the present invention, which is to easily perform the concentration and separation operations, and also to allow the wind direction division portions to be made independently of each other. However, in order to perform more delicate control of the wind direction, it may be further divided into smaller pieces 1, or conversely, it may be connected by a single connector 4 as shown in FIG. 2 without being divided.

The reason why the left 11*6 direction blade 5a and the right deflection blade 5b are curved is to not only deflect the wind direction by the Coanda effect but also to enhance the concentrated one-split flow effect that is the object of the present invention. As long as the effect is not taken into consideration, it may be a planar shape that is not curved, and furthermore, the opening direction 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 Suita mouth 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 1a facing the suction port 11, and a blower 16 is provided in the ventilation path from the indoor heat exchanger 15 to the outlet 12.

Next, FIG. 6 shows the refrigeration cycle of this embodiment.

In the same figure, the compressor has 1,740,000 valves and 18, and the indoor heat exchanger has 1
5. The capillary tube 19 and the outdoor heat exchanger 520 are connected in an annular manner. 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 indoor heat exchanger 20, 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.

Further, 21e is a temperature detector for detecting the suction temperature, and is -+21 of the 7114 degree detection means for detecting the room temperature, and the room temperature detection location is not limited to the vicinity of the suction port.

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 temperature, 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, and a drive signal generator 24 for the blower 16. It has a rotation speed variable means 29 that changes the rotation speed. A thermistor 21 serving as a temperature detection means is connected to the input side of this microcomputer via a comparator 25, and a thermistor 21 serving as a driving means is connected to the output side of the microcomputer via a buffer 26 that supplies pulse output to each motor 3, 9a, and 9b. The motor 3, left motor 9a, right motor 9b and blower 16 are connected. Here, 27 is a bias resistance, and 2nd is a scan resistance. Here, the third
The relationship between the block diagram shown in the figure and the circuit shown in FIG. 7 will be explained.

The thermistor 21 in FIG. 7 corresponds to the temperature detection means in FIG. 3, the storage section 23 in FIG. 7 corresponds to the set temperature storage means in FIG. 3, and the drive signal generation means 24 in FIG. It corresponds to the drive signal generating means in the figure, the seventh meat rotation speed variable means 29 corresponds to the rotation speed variable means in FIG. 3, and each motor 3 in FIG.
, 9a, 9b.

Reference numeral 16 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.

The blowout temperature t is the temperature detected by the thermistor 21, and tl is the set temperature. When this blowout temperature t is lower than the first set temperature t1, the rotation speed of the feeder 16 becomes low, and the middle motor 3 is rotated clockwise, 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 moves the upper deflection blade 1 to the horizontal position (upward position if necessary), and rotating the left motor 9a to the right moves the left deflection blade 5a to the left and the right motor 9b. Rotating to the left indicates driving the right deflection blade 5b to the right. In other words, the blown air is horizontally divided and the air volume becomes small, as shown in FIG. 9. 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 f15b are in, but each motor 9a
, 9b.

After driving 9c, it always rotates to the above 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 rotated by a load resistance such as a stopper, or the motor is idled. And each motor 9a, 9b,
9 After rotation of c (before or during rotation as necessary)
compares the thermistor 21-D temperature and the set temperature again.

Next, when the temperature t of the thermistor 21 is higher than the set temperature t1, 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 then stopped. In other words, the blown air is concentrated downward and the volume becomes large, as shown in FIG. 10.

By performing the above operation, the cold air, which is not pleasant for the human body, is diverted horizontally so that it does not directly hit the human body, and if the temperature of the air outlet is high enough, there is no problem even if the cold air blows directly onto the human body. A speech bubble appears in the lower part of the body.

The effect of such an operation at the beginning of the heating cycle will be explained. First, since the temperature of the air outlet immediately after the heating operation starts is low, it is not desirable for the air to directly hit 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. That is, by making the horizontal branch airflow and the atmosphere small, the air blown out mixes only in the L portion of the living space, thereby providing a heating effect without making the human body feel cold.

When the temperature of the airflow increases, the airflow concentrates downward and the volume of air increases, so warm air is directly applied to the human body.
Heating effect can be increased.

In this case, the walls are already warmed to some extent, so there will be no cold spots in the living space.

In the above embodiment, control during heating operation was explained by carrying out the above operations according to the temperature of the air outlet, but it is also possible to improve the ease of determining the occupancy level by carrying out the 1-recordability according to the room temperature. .

In other words, for example, when the room temperature has dropped to a certain level, the entire living space can be evenly cooled by making the horizontal branch air outlet small and the room temperature lower than the constant temperature. In other words, if the living space is large or people come in and out frequently, and if the air conditioner has sufficient capacity to cool the entire room, the air will blow out downwards and the lice will be large. By doing so, only the lower part of the living space is cooled by 11 times.

Comfort can be improved.

In addition, when the room temperature is high, such as at the start of cooling operation, the horizontal branch air blows out and cools the entire room, and after the room temperature drops to a certain temperature, it concentrates downward, reducing the compressor operating time. It is possible to provide effective cooling at a low and economical cost.

Effects of the Invention The present invention has the following characteristics that are clear from the description of the embodiments described above: When the air outlet temperature reaches a certain set temperature, the airflow becomes horizontally divided airflow, the air volume is small, and the air is concentrated downward, and the wind becomes a dog. When the blowout temperature is low, the air is mixed only in the upper part of the living space.

That is, at this time, since it is a horizontal outlet and a branch outlet, it is possible to improve the mixing effect of air only in the upper part of the room 1, and furthermore, because the atmosphere is small,
Large air movement in the lower part of the living space can be prevented by +1, so you won't feel the cold.

Furthermore, when the temperature of the airflow is high, the airflow is concentrated downward and the atmosphere is large, so warm air can be applied directly to the human body and the heating effect can be enhanced.

Furthermore, even when the above operations are performed due to changes in room temperature, effective heating and cooling can be performed in the same way.
