Description

TECHNICAL FIELD The present invention relates to a control method for louvers used for starting up heating of an air conditioner.

[Prior Art] A side view of the conventional air conditioner heating is shown in FIG.
As shown in the figure, the louver 02 is fixed at a position at an angle of 20 ° to 30 ° from the vertical plane of the wall surface to which the air conditioner 01 is attached so that the warm air can reach the center of the room directly.

[Problems to be Solved by the Invention]

The above conventional louver control method for an air conditioner has the following problems to be solved.

That is, since the louver position is fixed in the conventional method,
The wind direction is fixed. Therefore, the place where the hot air directly hits is fixed and the floor surface 03 is only partially warmed as shown in the side view of the room in FIG. Does not heat easily.

That is, there was a problem that the rise time of heating was delayed.

[Means for Solving the Problems] As a means for solving the above problems, the present invention is an air conditioner in which a horizontal louver provided at an outlet can be swung within a predetermined range and the swing speed is variable. When the difference between the room temperature and the set temperature is larger than a predetermined value in the louver control method, the louver is swung within a predetermined angle range, and the swing speed is set so that the angle formed by the louver initial position and the louver is A louver control method for an air conditioner, which is characterized in that the louver is fixed at a predetermined angle or more and becomes slower at a predetermined angle or less, and is fixed at a predetermined position when the difference between the room temperature and the set temperature becomes smaller than a predetermined value. It is the one we are trying to provide.

[Action]

Since the present invention has the above configuration, it has the following effects.

(1) By rotating the louver, warm air directly reaches all parts of the room, heat is not concentrated at some parts, and convection is diversified, so that the entire room is warmed uniformly. The heating starts up quickly.

(2) When the angle between the louver and the vertical direction is large, the wind direction is far in the room, so slowing the louver speed allows warm air to reach far. When the angle is small, the wind direction immediately approaches the floor surface, so even if the louver speed is increased, the wind directly reaches the floor surface and the heat quantity is not concentrated in one place.

(3) When the difference between the room temperature and the set temperature becomes small, the louver is fixed so that the wind is directed directly to the place where the user is, for example, in the center of the room, and the comfort level is increased.

〔Example〕

A method according to an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a configuration diagram schematically showing a louver of an air conditioner and a controller thereof for implementing the method of the present invention, a louver 1, a stepping motor 2 for driving the louver 1,
It consists of a louver 1 for detection, a limit switch 3, a controller 4, a temperature setter 5, and a room temperature sensor 6. A power switch (not shown) is turned on, the stepping motor 2 is driven, and the louver 1 is rotated to initialize the louver 1. A signal S1 that detects the position with an initial position detection signal S3 from the limit switch 3 and determines the rotation direction of the stepping motor 2 from the controller 4, and a pulse signal S2 that moves the stepping motor 2
Drives the stepping motor 2 to rotate the louver 1. Although the limit switch 3 is used to detect the position of the louver 1, a photoelectric element may be used so that the louver 1 blocks light.

With these configurations, first, as shown in FIG. 2, the louver 1 and the limit switch 3 form an angle C1.
A case will be described in which the control is performed within the range of 1 to 2 degrees (C1 <C2). First, the controller 4 continues to send the pulse signal S2 for driving the stepping motor 2 until the louver 1 pushes the limit switch 3 to detect the initial position, thereby moving the louver 1. When the louver 1 pushes the limit switch 3 and the controller 4 receives a signal for detecting the position of the louver 1, the controller 4 sends the signal S2 for driving the stepping motor 2 only C2 / k pulse. However, k (degree / pulse) is a lead angle per pulse. ; Inverts the pulse signal S1 in the rotation direction of the stepping motor 2,
The rotation direction of the stepping motor 2 is changed. The signal S2 for driving the stepping motor 2 is Send only pulses. The above items and items are repeated until the difference between the room temperature and the set temperature of the temperature setting device 5 becomes small. Thereby, the louver 1 can be rotated within an arbitrary range. Next, the operating speed of the louver 1 can be arbitrarily set by changing the pulse interval of the drive pulse signal S2 of the stepping motor 2. Now, an arbitrary angle formed by the louver 1 and the vertical plane is x degrees, and when the x is large, the louver 1 is moved slowly, and when the x is small, it is moved quickly. For example, the pulse interval f (x) of the drive pulse signal S2 of the stepping motor 2
May be f (x) = EXP [x] or f (x) = x. The value of x is determined by the number of pulses from when the louver 1 presses the limit switch 3 and the number of inversions of the signal S1 that determines the rotation direction of the stepping motor 2 (see FIGS. 2 and 3).

The above control process is shown in the flow chart of FIG. Further, FIG. 6 shows a schematic diagram of convection occurring in the room when the louver 1 has a large angle, and FIG. 7 shows a schematic diagram of convection when the louver 1 has a small angle.

Next, as an example of a method of stopping the louver 1 at an arbitrary position for an arbitrary time, as shown in FIG. 5, the louver 1 is stopped at a position where the angle formed by the louver 1 and the vertical plane is C3 degrees. explain. Now, the difference between the room temperature and the set temperature of the temperature setting device 5 is 1
When it becomes smaller than ℃, when the louver 1 is moved by continuously sending the drive pulse signal S2 of the stepping motor 2 and the louver 1 is rotated to push the limit switch 3, the signal from the limit switch 3 enters the controller 4. It is enough to stop the louver 1 by sending only C3 / k pulse from. After that, it may be fixed for an arbitrary time. The above control process is also shown in the flow chart of FIG.

As described above, according to the method of the present embodiment, when the difference between the room temperature and the set temperature of the air conditioner is large, the operation angle of the louver can be large and can be slowly moved, and the warm air can be blown in and out of the room. Since it spreads over time, it is possible to accelerate the rise of heating. Further, when the room is sufficiently warmed, a person can fix the louver only at the living position so that a slight breeze blows out, so that there is an advantage that comfortable air conditioning can be obtained without being exposed to a strong blowout flow.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

That is, according to the louver control method of the present invention, when the difference between the room temperature and the set temperature is as large as 1 ° C. or more during heating, the louver is swung within a predetermined range to distribute the warm air throughout the room. The temperature difference in the room is reduced to make the rise time faster, and if the difference is less than 1 ° C, the louver can be fixed and comfort can be maintained, so that quickness and comfort of heating can be satisfied at the same time.
