Abstract

PURPOSE:To uniformize temperature distribution and improve the comfortable property of a living space employing an air-conditioning machine upon starting cooling operation by cooling a human body directly in the initial period of operation and, thereafter, cooling wall surfaces of the space or the like. CONSTITUTION:The titled air-conditioning machine drives a deflecting vane 1 downward, the deflecting vane 5a rightward and the deflecting vane 5b leftward upon starting the cooling operation thereof. In this case, the blow-off air of the machine is concentrated downward. According to this operation, a human body is cooled quickly. When time is elapsed in some degree, the deflecting vanes 5a, 5b are deflected oppositely to blow off the cooling air downwardly while branching it to cool the circumference of the human body as well as the wall surfaces. When the time of operation is elapsed further, the deflecting vane 1 is deflected upwardly. In this case, the blow-off air is distributed horizontally and the whole of a room may be cooled. According to this method, comfortable room cooling effect may be obtained.

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, there is a device in which the upper and lower deflection blades are swung at a constant period. (Japanese Patent Publication No. 56-21149) Problems to be Solved by the Invention However, the above conventional configuration can only control the deflection in the vertical direction, and the left and right deflection is manual, so only a limited space can be cooled. There wasn't. Another problem was that the temperature distribution in the room deteriorated. Furthermore, since air swing occurs from the start of operation, there is a problem in that cold air does not hit the human body at the start of cooling operation, making it impossible to obtain a sufficient cooling effect.

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

Means for Solving the Problems In order to solve the above problems, the present invention compresses a refrigerant,
The compressor, which together with the indoor heat exchanger and outdoor heat exchanger constitute a refrigeration cycle, the blower, and the indoor heat exchanger are installed within 1M.
an indoor unit having an indoor unit, an air outlet provided in the indoor unit that blows out air that has passed through the indoor heat exchanger, a vertical deflection blade that vertically deflects air blown out from the air outlet, and the air outlet. Left and right deflection vanes are provided independently on the left and right sides of the air outlet and branch and deflect the air blown out from the air outlet into left and right winds, and the upper and lower deflection vanes and the left and right deflection vanes described in nfj are each independently deflected. a driving means; an elapsed time detecting means for detecting the elapsed time since the air conditioner performed a certain operation; a set time storing means for storing a preset time; and detecting that the elapsed time detected by the elapsed time detection means has reached the first elapsed time stored in the set time storage means in a state where the vertical deflection blades and the left and right deflection blades are concentrated; The upper and lower deflection blades maintain the above state, the left and right deflection blades are rotated from a concentrated position to a position where they diverge to the left and right, and it is detected that a second elapsed time has elapsed since the start of the set operation. The apparatus further includes drive signal generating means for supplying to the drive means a signal for rotating the vertical deflection blade from a downward direction to a horizontal or upward position.

Operation With the above configuration, the air deflection device of the air conditioner of the present invention concentrates downward when the air temperature is high, such as when starting cooling operation, so that the cold air directly hits the human body and a rapid cooling effect can be obtained. . In addition, after a certain period of time after the start of operation, the temperature of the air outlet drops to a certain extent, causing discomfort if the cold air is applied directly to the human body, but when the temperature has fallen sufficiently for the living space, the air is diverted downward, so the user can live without being directly exposed to cold air. Cooling can be done to wrap around the lower part of the room, which improves the experience. When the above operation passes for a predetermined period of time, that is, when the blowout temperature drops, the airflow becomes horizontally divided, allowing the air to flow from the top to the bottom of the room without directly applying cold air, resulting in a cooling effect that is close to natural.0 Implementation EXAMPLE A wind direction deflection device for an air conditioner according to an embodiment of the present invention will be described below 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 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 blades that horizontally deflect the blown air by the Coanda 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
Feather lever arm 6a, Ron door a.

It is connected to a left motor (stepping motor) 9a via a motor lever arm 8a, and the right deflection blade 5b is connected to a blade lever arm 6b and a rod 7b.

It is connected to a right motor (stepping motor) 9b via a motor lever arm 8b. Here, left deflection blade 5
The left deflecting blade 5b is slightly curved so as to have its center to the left of the left deflecting blade 5a, and the right deflecting blade 5b is slightly curved to have its center to the right of the right deflecting blade 5b. That is, both sides 13a of the air outlet 12 described later
・This is to generate the Coanda phenomenon described in rjfI with 13b and deflect the wind direction. Since the coring effect described in box is a well-known technique, a description thereof 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. 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, it may be further divided into smaller sections, or conversely, it may be connected by a single connecting bar 4 as shown in FIG. 2 without being divided. In addition, the left deflection blade 5a1 and the right deflection blade 5b are curved in order to deflect the wind direction by the Coanda effect and also to enhance the concentration and splitting effect that is the object of the present invention, taking into consideration the Coanda effect. If not, it may be a planar shape that is not curved, or even a shape in which the concave and concave directions are reversed.

Next, FIG. 3 shows a perspective view of the indoor unit 1o 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 for sucking indoor air, and a suita port 12 having a vertical deflection blade 1 and left and right deflection blades 5a and 5b is provided below the suction port 11. There is. Both sides 1 of this outlet 12
3a and 13b each have a curved surface that gradually expands 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 this embodiment is shown in FIG.

In the figure, a compressor 17, a four-way valve 18, an indoor heat exchanger 15, a capillary tube 19, and an outdoor heat exchanger 2o are connected in a ring. Here, the refrigerant is KI/
i, the compressor 17, the four-way valve 1B, the indoor heat exchanger 15, the capillary tube 19, and the outdoor heat exchanger 20 flow in this order, and during cooling operation, the compressor 17, the four-way valve 18, the outdoor heat exchanger 20, and the capillary tube 19 , and the indoor heat exchanger 15 in this order.

Here, 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 time, and a drive signal generation means 24 that generates an appropriate output signal by comparing the set value stored in the storage section 23 with an input value. ing. On the input side of this microcomputer, there is a timer 2 which is a time detection means.
1, and the middle motor 3, left motor 9a, and right motor 9b, which are driving means, are connected to the output side of the motor 3.9a, 9b via a buffer 27 that supplies pulse output to each motor 3. 29 is a timer coil.

When explaining the relationship between the block diagram shown in FIG. 11 and the circuit shown in FIG. 6, the timer 21 in FIG. 6 corresponds to the time detection means in FIG.
The drive signal generation means 24 in FIG. 6 corresponds to the set time storage means in FIG. 11, and the drive signal generation means 24 in FIG.
Each motor 3.9a, 9b in the figure corresponds to the drive means in FIG. 11.

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

The operating time t is the time detected by the timer 21 and is tl・
t2 is a set time.

- When this operating time t is less than the first set time t1, the middle motor 3 is rotated to the left, the left motor 9 & is rotated to the left, and the right motor 9b is rotated to the right and then stopped. Here, rotating the middle motor 3 to the left means moving the upper and lower deflection blades 1 to the lower position, and rotating the left motor 9af 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 1 to the lower position. 5b is shown to be driven to the left. That is, the blown air is concentrated downward, as shown in FIG. 10. 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 after each motor 3, 9a19b is driven, they must be rotated to the above positions. It is something that moves.

That is, when the deflection is already at the same position as the position after driving in the initial state example, the motor is not rotated by a load resistance such as a stopper, or the motor is idled. After each motor 3.9a, 9b has rotated (before or during rotation, if necessary), the time set in the timer 21 is again compared with the set time.

Next, if the time t of the timer 21 is longer than the first set time and less than the second set time t2, 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. Stop. In other words, the blown air becomes a downward branch,
The result is as shown in FIG. When it is already concentrated downward in FIG. 10 before this operation, the right deflection blade 5a1 is substantially
Only 5b is deflected.

Next, when the timer 21 reaches the second set time t2 or more, 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. That is, the blown air becomes horizontally divided as shown in FIG.

By performing the above operation, when the temperature of the air outlet is high, such as at the start of operation, the cold air is concentrated downward, as if directly hitting the human body, and when a certain amount of time has passed and the temperature of the air outlet has cooled down, it indirectly hits the human body. It becomes a downward branch to cool it,
When sufficient operating time has elapsed and the blowout temperature is low enough, the flow becomes horizontally divided to cool the entire room.

The effect of such an operation at the start of cooling operation will be explained. First, since the air temperature at the start of cooling operation is high, unless the air is applied directly to the human body, it will take too long for the air to cool down. Therefore, it is preferable to apply wind directly to the human body. In other words, by directing the air to the air in a downward direction, a cooling effect that can cool the human body more quickly is achieved.

Next, when a certain amount of time has passed and the temperature of the air outlet becomes high, the air outlet is diverted downward, so that cooling can be performed in a way that envelops the lower part of the room near the living space. That is, by bathing the area around the human body and cooling the wall surface, the temperature distribution within the living space can be made uniform.

When the operating time further passes and the blowout temperature becomes lower, the flow becomes horizontally divided, so that a sufficient cooling effect can be obtained without directly blowing cold air to the human body. That is, in the initial stage, the human body is directly cooled, and the walls and the like are later cooled, so that the temperature distribution is uniform, and there are no local hot spots in the living space.

Effects of the Invention As is clear from the description of the above embodiments, the present invention, when the time from the start of operation is shorter than a certain set time, will concentrate downwards, so the wind will be directed directly to the human body to enhance the sensory effect, thereby making the process faster. A falling effect can be obtained.

Next, when the above-mentioned operating time reaches a certain set time, the flow is diverted downward to cool the wall surface without impairing the bodily sensation, thereby making the temperature distribution in the living space uniform.

When the operation continues and the second set time is reached, the flow becomes horizontally divided, making the temperature distribution even more uniform, eliminating local hot spots, and at the same time providing a comfortable cooling effect by blowing cold air from above. can get.
