It characterized in that it includes the step of stopping.

Hereinafter, the configuration and the effect according to the preferred embodiment of the present invention will be described in detail.

(A) and (b) of FIG. 2 are schematic perspective views showing the opening and closing states of the automatic shutter apparatus of the air conditioner of the present invention, respectively. As shown in FIG. 2, in the air conditioner to which the present invention is applied, a suction grill 102 for sucking air in the room is formed in the front lower part of the main body 100, and a suction part is formed in the central portion of the main body 100. An indoor heat exchanger (not shown) for heat-exchanging indoor air sucked through the grill 102 is disposed. At an adjacent position to the indoor heat exchanger, an indoor air fan (not shown) for forcibly discharging the heat-exchanged air toward the upper side of the main body 100 is mounted. The upper end of the main body 100 functions as an outlet for opening and heat-exchanging air. On the other hand, the upper portion of the main body 100 is installed so that the automatic shutter 106 is movable up and down, the automatic shutter 106 is formed in the shape of the enclosure, the lower portion and the front surface of the predetermined portion respectively. In the front discharge port 106a of the automatic shutter 106, a wind direction control blade 108 for adjusting the wind direction is rotatably mounted.

Therefore, while the air conditioner is not used, the automatic shutter 106 is moved downward as shown in FIG. 2A, so that the upper wall of the automatic shutter 106 blocks the discharge port of the main body 100. While the air conditioner is in use, the automatic shutter 106 is moved upward as shown in FIG. 2 (b) to open the discharge port of the main body 100 so that the air discharged through the discharge port is discharged from the automatic shutter 106. It is discharged into the room via the front discharge port (106a) and the wind direction control blade (108). Reference numeral 104 is an operation unit.

3 is a rear perspective view showing the lifting means of the automatic shutter device of the air conditioner of the present invention. As shown in FIG. 3, an opening / closing motor 111 for opening and closing the automatic shutter 106 is fixedly mounted on the rear surface of the main body 100, and the pinion 112 is axially coupled to the shaft of the opening / closing motor 111. do. On the other hand, the rack 113 is vertically extended in a state where one end is fixed to the rear surface of the automatic shutter 106 by the fastening member 114 is engaged with the pinion 112, thereby moving the rotary motion of the pinion 112 up and down straight The motion is converted into motion, and the automatic shutter 106 is opened and closed by this.

When the pinion 112 is reversely rotated by the forward and reverse rotation of the motor 111, the lifting means 110 of the automatic shutter lifts the automatic shutter 106 by linearly reciprocating up and down. Therefore, the air sucked through the suction port 102 by the driving of the indoor fan is discharged to the room through the discharge port 106a formed at the upper end of the main body 100, in which case the opening and closing according to the lifting degree of the automatic shutter 106 The degree of the discharge port 106a to be changed.

In addition, the rear side of the automatic shutter 106, as well as descending and descending of the automatic shutter 106 according to the forward and reverse rotation of the motor 111, and is raised and lowered in place at the height of the start groove 121a and the automatic shutter 106 The sensor driver 121 having a plurality of grooves 121b-121f formed at predetermined equal intervals is fixedly coupled by the predetermined fastening member 122 to correspond to each other. On the rear surface of the main body 100, the suction port 102 is moved by a plurality of grooves 121a-121f formed in the sensor driver 121 and an optical sensor 123 having a light receiving unit 123b and a light emitting unit 123a is provided. Is mounted, in conjunction with the lifting of the automatic shutter 106, the sensor driver 121 is raised and lowered between the light emitting unit 123a and the light receiving unit 123b of the optical sensor 123 is formed in the sensor driver 121. The driving of the optical sensor 123 is turned on and off by a plurality of grooves 121a-121f. Including the sensor driver 121 and the optical sensor 123 constitutes the lifting detecting means (120).

In addition, as shown in FIG. 4, the automatic shutter apparatus of the air conditioner according to the present invention includes a power supply unit 131 for supplying driving power, a motor driving unit 132 for controlling forward and reverse rotation of the motor 111, The automatic control unit receives a predetermined height level set by dividing the lifting height of the desired automatic shutter 106 into a predetermined range, and receives the automatic operation from the key operation unit 134 to the selected step from the key operation unit 134. Lifting detection means 120 for detecting whether the shutter 106 is raised and lowered, the load driving unit 135 for controlling the drive of the compressor, the fan and the wind direction control blade 108, and the detection result of the lifting detection means 120 The control unit 130 receives the input and outputs a control signal to the motor driving unit 132 to control the driving of the motor 111.

In the above configuration, the sensor driver 121 is moved up and down between the light receiving unit 123b and the light emitting unit 123a of the optical sensor 123 by the forward and reverse rotation of the motor 111, the sensor driving unit ( When the plurality of grooves 121a-121f formed in the 121 are placed at an appropriate position, the light emitted from the light emitting unit 123a is received by the light receiving unit 123b through the grooves 121a-121f, and thus the controller 130. ) Is to determine the lifting height of the automatic shutter 106 by counting the number of detection signals input from the optical sensor 123.

At this time, the plurality of grooves 121a-121f formed in the sensor driver 121 detect the lifting height of the automatic shutter 106 to the height corresponding to the first stage in proportion to the lifting height of the automatic shutter 106. The first groove 121b and the second groove 121c for detecting the lift to the height corresponding to the second stage of the automatic shutter 106 are formed, and the third groove 121d, the fourth groove 121e, The fifth groove 121f is set in proportion to the lifting height of each automatic shutter 106. However, the lifting height of the automatic shutter 106 is 1 stage, 2 stage, 3 stage, 5 stage relationship.

That is, the sensor driver 121 is a control unit because the automatic shutter (106) is completely lowered and the discharge port (106a) is completely blocked, the light is continuously received by the start groove (121b) to the light receiving unit (123b) for a predetermined time. The high signal is input to 130. In addition, when a step corresponding to a predetermined lifting height of the automatic shutter is input by the user, the motor 111 is rotated forward to raise the automatic shutter 106, and the sensor driving unit is linked to the automatic shutter 106. 121) is raised.

At this time, if the user inputs the lifting height of the automatic shutter 106 in three stages, the controller 130 according to the driving of the motor 111 in the state in which the high signal is input to the control unit 130 by the start groove 121a. ) Is raised and the received light is temporarily blocked, so the low signal is input. In addition, the control unit 130 according to the elevation of the automatic shutter 106, the first groove 121b and the second groove 121c and the like to the appropriate height corresponding to the position of the light receiving unit 123b and the light emitting unit 123a. In every case, the high signal is inputted.

Therefore, the controller 130 rotates the motor 111 forward until the high signal is input by the third groove 121d of the sensor driver 121 so that the automatic shutter 106 has a height corresponding to the three stages. If the high signal is input by the third groove 121d, the driving of the motor 111 is stopped. At this time, the controller 130 counts the number of times the high signal is input from the optical sensor 123 after the step corresponding to the lifting height of the automatic shutter 106 is input and whether the automatic shutter 106 is lifted until the desired step. Determine and stop the motor 111 to stop the lifting of the automatic shutter 106. In addition, when the lifting and lowering of the automatic shutter 106 is stopped, the counted value is stored.

When the user stops the air conditioning operation and tries to close the discharge port 106a by lowering the automatic shutter 106, the user rotates the motor 111 in reverse to lower the automatic shutter 106 and the sensor driver 121. As light is received in the light receiving unit 123b of the optical sensor 123 by each groove according to the descending of the sensor driver 121, each time a high signal is input from the optical sensor 123, the count is 1. Subtract by Therefore, when the value of the count reaches 0, that is, when the lowering of the sensor driver 121 is completed and the start groove 121a is positioned between the light emitter 123a and the light receiver 123b, the driving of the motor 111 is stopped. To stop the falling of the automatic shutter 106.

The automatic discharge opening and closing control method will be described in detail with reference to the flowchart of FIG. First, when the initial driving power is applied in step S10, a step corresponding to the lifting height of the desired automatic shutter is input from the user in step S12, and the count is initialized in step S14. At this time, since the start groove 121a is positioned at the position corresponding to the light emitter 123a and the light receiver 123b, a high signal is input to the controller 130.

In step s16, the lifting step of the automatic shutter 106 selected by the user in the step s12 is determined, and the lifting step of the automatic shutter 106 set by the user is N steps (for example, one step). In step S18, the motor 111 is rotated forward to raise the automatic shutter 106, and the automatic shutter 106 raises the Nth groove (eg, between the light emitting part 123a and the light receiving part 123b). For example, a high or low signal is input to the controller 130 depending on whether the positions of the first grooves 121b correspond to each other. Therefore, the controller 130 increases the value of the count by one each time the high signal is input from the photosensor 123 to determine whether the automatic shutter 106 has risen to the height set by the user. .

That is, in step s22, it is determined whether the count value is N (for example, 1), and in the case of 1, the automatic shutter is increased by a height corresponding to the distance of the first groove 121b from the start groove 121a. In step S24, the driving of the motor 111 is stopped to complete the raising of the automatic shutter 106.

In step s26, the air conditioner is operated to provide a desired air conditioning environment by driving a compressor and a fan by receiving a desired room temperature and wind direction from a user. In step s28, it is detected whether the operation stop signal is input during the execution of the heating and cooling operation. If the operation stop signal is input, the motor 111 is reversely rotated to proceed to step s30 to lower the automatic shutter 106. Let's do it.

At this time, the automatic shutter 106 is lowered by the reverse rotation of the motor 111, so the sensor driver 121 is lowered accordingly, so in step s32, the counter is counted as many times as the high signal is input from the optical sensor 123. Will be subtracted. This is because the count of 1 is stored in the process s20, the count value becomes 0 when the start groove 121a is placed at a corresponding position between the light emitting unit 123a and the light receiving unit 123b. Therefore, if the count value is 0 in step S34, the process proceeds to step S36, and the automatic shutter 106 determines that the starting groove 121a is lowered to the original position where the start groove 121a is sensed, thereby stopping the driving of the motor 111. Let's do it.

In the above, the case where the user sets the opening / closing degree to the first stage has been described. However, the case where the user sets the second stage, the third stage, or the fourth stage and the fifth stage is also performed by the same method as described above. The driving of is controlled. However, the control unit 130 rotates the motor 111 forward to raise the automatic shutter 106, and then the number of times detected by the optical sensor 123 is the number of times proportional to each lifting step in step s22. When counting up to 2, 3, 4, and 5, the driving of the motor 111 is stopped in step s24 to complete the ascent of the automatic shutter 106, and the counted value is stored.

In addition, when the automatic shutter 106 is to be lowered, the motor 111 is reversely rotated, and each time a detection signal is input by the optical sensor 123 as the automatic shutter 106 is lowered, the counted value is 1 by one. When the count value becomes 0 by subtracting, the driving of the motor 111 is stopped and the lowering of the automatic shutter 106 is completed to adjust the lifting height of the automatic shutter 106.

As described above, by setting the lifting height of the automatic shutter in multiple stages by the automatic shutter device and the control method according to the present invention, the position of the discharge port can be changed by elevating the automatic shutter to the desired stage by the user. Variable lengths provide storage advantages when transporting or not in use.
