As illustrated, the air conditioner includes: a main body 11 having air inlets 12 to allow air to enter the lower region, and air outlets 14 to discharge air to the upper region, respectively; Heat exchanger 15 that exchanges heat while the air introduced through air inlet 12 passes through the main body 11 is disposed above the internal heat exchanger 15 of the main body 11 to promote the flow of air. It has a blowing fan 17 to be.

In the adjacent area of the internal air discharge port 14 of the main body 11, a plurality of upper and lower control plates 19 are installed to be rotatable along the up and down direction of the main body 11 to adjust the wind direction of the discharged air. On the upstream side of the upper and lower control plates 19 with respect to the discharge direction, a plurality of left and right control plates 21 are installed to be rotatable along the left and right directions of the main body 11 to adjust the wind direction. These top and bottom control plate 19 and the left and right control plate 21 is integrally connected to each other to be interlocked, and each one of the upper and lower control panel 19 or the left and right control plate 21 so as to automatically adjust the wind direction is shown in the rotational shaft Drive motor is provided.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

3 is a control block diagram of the wind direction control device of the air conditioner according to an embodiment of the present invention, Figures 4a and 4b is a view showing the rotational speed curve in the constant speed mode of the upper and lower control plates and the left and right control plates, respectively, 5A and 5B are diagrams showing the rotation speed curves in the near-air blowing mode of the upper and lower control plates and the left and right control plates, respectively. The same reference numerals are given to the same and equivalent parts as the above-described air conditioners. As shown in these figures, the wind direction control device of the present air conditioner includes a control unit 31 composed of a microcomputer or the like in which a control program is built so as to form different cooling zones, upper and lower control plates 19 and left and right sides. The mode setting unit 33 sets the mode so that the control plate 21 is operated in any one of a plurality of operation modes operated along different rotation speed curves, and the upper and lower control plates 19 and the left and right control plates 21 are rotated, respectively. It is configured to include a vertical control plate driving motor 35 and the left and right control plate driving motor 37 which is connected to the upper and lower control plate 19 and the left and right control plate 21 so as to be able to.

The upper and lower control plates 19 are installed to be rotatable along the vertical direction with an upper limit value (α ° + a °) and a lower limit value (α ° -b °) with respect to the reference angle (α °) with respect to the main body 11, The left and right adjustment plates 21 have a left limit value (β ° + c °) and a right limit value (β ° -d °) with respect to the reference angle (β °) with respect to the main body 11 so as to be rotatable along the left and right directions. It is installed. Hereinafter, for convenience of explanation, a and b are the same as each other, and c and d are regarded as the same.

The mode setting unit 33 includes a fixed mode in which the upper and lower control plates 19 and the left and right control plates 21 are fixedly disposed at a predetermined position with respect to the air outlet 14 so that the air is discharged in a predetermined direction, and the upper and lower control plates 19. And the left and right control panel 21 rotates each rotation angle between the tools at a constant speed with respect to the air discharge port 14 in the vertical direction or the left and right direction, and the upper and lower control plate 19 and the left and right control plate 21 is different from each other It is configured to select shifting mode that rotates with average rotation speed.

In the shift mode, the average rotational speed in the first section including positions (α ° and β °) in which the upper and lower control plates 19 and the left and right control plates 21 are arranged in parallel with the edges of the air discharge port 14, respectively, is the upper and lower control plates. (19) and the left and right adjustment plates 21 have respective limit values (α ° + a °, α ° -b °, β ° + c °, β ° -d °) for each reference angle (α ° and β °). In the near-air blowing mode, which has a speed faster than the average rotation speed in the second section and the third section including the position having a position, the average rotation speed of the second section and the third section is relatively slower than the average rotation speed of the first section. It is configured to include long distance blowing mode.

Each of the rotational speed curves of the upper and lower control plates 19 and the left and right control plates 21 in the constant speed mode has a triangular wave shape, as shown in FIGS. 4A and 4B. As shown in Fig. 5B, it has a sinusoidal wave shape.

In the constant speed mode, the upper and lower control plates 19 and the left and right control plates 21 each have a limit value (α ° + a °, α ° -b °, β ° + c °, β ° -d °). The rotation speed of each wind direction control plate at point e and point g is 0, and the angle between each limit value (α ° + a °, α ° -b °, β ° + c °, β ° -d °) The rotation speed of the wind direction control plate is constant.

The upper and lower control plate driving motor 35 and the left and right control plate driving motor 37 are each composed of a stepping motor in which the rotation angle is shifted in proportion to the number of input pulses and the rotation speed is changed in proportion to the input frequency.

On the other hand, since the control method for the rotational speed of the upper and lower control plate 19 and the left and right control plate 21 is almost the same will be described below limited to the left and right control plate (21).

When the operation mode of the left and right adjustment plate 21 is set to the constant speed mode by the mode setting unit 33, the control unit 31 senses the position of the left and right adjustment plate 21 and as shown in FIG. 4B, the left and right adjustment plate 21. ) Controls the left and right adjustment plate driving motor 37 to rotate in the left and right direction with the same rotation speed. At this time, the air heat-exchanged while passing through the heat exchanger 15 is discharged through the air discharge port 14 by the blowing fan 17 rotating at a constant speed, by the left and right control plate 21 to rotate left and right at the same speed It is diverted and discharged from the air discharge port 14 to form a cooling zone having an almost fan shape.

On the other hand, when set to the near-air blowing mode by the mode setting unit 33, the control unit 31, as shown in Figure 5b, the left and right adjustment plate driving motor 37 so that the rotational speed curve of the left and right adjustment plate 21 forms a sine wave shape. Will be controlled. That is, the left and right adjustment plate 21 includes a point e and a point g having a left limit value (β ° + c °) and a right limit value (β ° -d °), and are formed around the points e and point g. In this case, the motor rotates at a relatively slow rotational speed compared to the section including points f and h having a reference angle (β °). Then, since the discharge speed of the heat-exchanged air passing through the heat exchanger 15 is constant, the left limit value (β ° + c °) and the right limit value (β ° -d) compared to the direction having the reference angle (β °) By discharging a relatively large amount of air in the direction of (°), air discharge in the direction of the reference angle (β °) of the main body 11 is suppressed, and the left limit value (β ° + c °) and the right limit value (β °) The air discharge in the -d °) direction increases, so that the cooling zone is mainly formed in the peripheral region of the main body 11.

FIG. 6 is a view illustrating a rotation speed curve of the left and right control plates in the long distance air blowing mode of the air conditioner of FIG. 3. As shown, the rotation curve in the long-distance blowing mode includes a reference angle (β °) and the left and right adjustment plates 21 adjust the angle between the reference angle (β °) and the left limit value (β ° + c °). The first position (β ° + c ° / 2), which is arranged to be divided into two, and the second position (β ° -d °, which bisects the angle between the reference angle (β °) and the right limit value (β ° -d °). / 2) a first section formed between the second section, the left and right adjusting plate 21 is rotated back to the first position from the first position via the left limit value (β ° + c °), and the second position 1 cycle is formed including the 3rd section which rotates back to a 2nd position via right limit value ((beta) -d (degree) from WHEREIN).

Here, the first section corresponds to half of the total rotational angle range of the left and right adjustment plate 21, and the sum of the second section and the third section is half of the entire rotational angle range of the left and right adjustment plate 21. The first to third sections are formed by quadratic function curves having different inclinations, and the rotation speed curves C1, C3, C4, and C6 of the first section have the same absolute value of the inclination, and the rotation speed of the second section. The curves C2 and C5 have the same absolute value of the slope and are formed so that the absolute value of the slope is larger than the rotational speed curve of the first section.

When the long distance blowing mode is set by the mode setting unit 33, the control unit 31 first checks the current position of the left and right control plates 21. Assuming that the left and right adjustment plates 21 are at the reference angle β °, the rotation speed curve C1 is adjusted so that the left and right adjustment plates 21 can reach the first position (β ° + c ° / 2) at the time point t1. The left and right control plate driving motor 37 is controlled accordingly. Next, the control unit 31 again passes through the position where the left and right control plates 21 have the left limit value (β ° + c °) at the first position (β ° + c ° / 2) within the time points t1 and t3. The left and right adjustment plate driving motor 37 is controlled along the rotational speed curve C2 to return to the first position β ° + c ° / 2. Accordingly, the left and right adjustment plate 21 is again in the first position (β °) via the position having the left limit value (β ° + c °) from the first position (β ° + c ° / 2) for a relatively quick time. Return to + c ° / 2).

From the time points t3 to t5 again, the left and right control plates 21 rotate along the rotation speed curves C3 and C4 having relatively slow average rotation speeds, and the rotation speed curve C5 having relatively fast average rotation speeds between the time points t5 to t7. Next, the left and right control plate driving motors 37 are respectively controlled, and at time t7, the left and right control plate driving motors 37 are respectively controlled along the rotational speed curve C6 having a relatively slow average rotational speed.

As described above, in the long distance blowing mode, the left and right control plates 21 rotate with a relatively quick average rotation speed in the second section and the third section as compared to the first section, and the blower fan 17 rotates at a constant rotation speed. The air discharged from the air discharge port 14 at a constant speed by) is compared to the left limit value (β ° + c °) and the right limit value (β ° -d °) directions of the main body 11. It is relatively discharged in the β °) direction.

FIG. 7 is a view illustrating a comparison between the cooling zones for each operation mode of the wind direction control apparatus of the air conditioner of FIG. 3. Here, A1 to A4 denote cooling zones formed by the air discharged through the air discharge port 14 in the near-air blowing mode, the long-distance blowing mode, the constant speed mode, and the fixed mode, respectively, and the blowing fan in each operation mode ( The rotation speed of 17) is the same. As shown, in the constant speed mode, the left and right control plates 21 are rotated at the same rotational speed, so that the cooling zone formed by the discharged air has a fan shape such as A3. As described above, the rotational speed of the left and right adjustment plates 21 adjacent to the left limit value (β ° + c °) and the right limit value (β ° -d °) is slow, and the reference angle (β °) direction is used. Since the rotation speed in Es is relatively fast, it forms a cooling zone like A1.

On the other hand, in the long-distance blowing mode, the average rotational speed in the section including the reference angle (β °) is the average in the section including the left limit value (β ° + c °) or the right limit value (β ° -d °). Since it is relatively slower than the rotation speed, air reaches farther in the direction of the reference angle (β °) than in the constant speed mode, and the left limit value (β ° + c °) and the right limit value (β ° -d °) In the direction, a cooling zone like A2 is formed, which has a shorter air reach than in the constant speed mode.

In addition, A4 is a cooling zone formed when each of the left and right control plates 21 is fixed in the reference angle (β) direction, and has a relatively far reaching distance of air as compared to the constant speed mode and the long blowing mode.

8A and 8B are diagrams illustrating a rotation speed curve of the left and right control plates of the wind direction control apparatus of the air conditioner according to another embodiment of the present invention, respectively. As shown in these figures, the air discharged through the air discharge port 14 is directed to the left limit value (β ° + c °) and the right limit value (β ° -d °) relative to the reference angle (β °) direction. In order to discharge a relatively large amount, as shown in FIG. 8A, the left and right adjustment plates 21 are positioned at the positions having the left limit value (β ° + c °) and the right limit value (β ° -d °). Is stopped for a predetermined time t20, and the left and right control plates 21 are operated at the same rotational speed in the region between the left limit value β ° + c ° and the right limit value β ° -d °.

On the contrary, in the case where the discharged air is to be discharged relatively in the reference angle (β °) direction relative to the left limit value (β ° + c °) and the right limit value (β ° -d °), As shown in 8b, the left and right adjustment plates 21 may be stopped for a predetermined time t30 at the reference angle β ° and rotated at the same speed in the remaining sections.

Here, the left and right adjustment plate 21 is configured to appropriately shift (accelerate or decelerate) between the reference angle (β °) and the left limit value (β ° + c °) and / or the right limit value (β ° -d °). You may.

In the above-described and illustrated embodiments, the rotational speed curves of the left and right control plates and the up and down control plates have been described with examples of a primary function curve, a secondary function curve, and a sinusoidal shape, but the third function curve, the exponential function curve, and the like. Of course, it can be configured to have a function curve shape and other.

As described above, according to the present invention, there is provided a wind direction control apparatus and a wind direction control method of an air conditioner capable of effectively achieving cooling and / or heating of a desired area by controlling the reach of air.
