Hereinafter, the effect of the humidity control device and the method of the air conditioner configured as described above will be described.

5A to 5D are flow charts showing the humidity control operation procedure of the air conditioner according to the present invention. In Figs. 5A to 5D, S denotes a step.

As an initial condition for explaining the operation of the present invention, it is assumed that the suction port 3 and the discharge port 7 are closed.

First, when power is applied to the air conditioner, the power supply means 100 converts a commercial AC voltage supplied from an AC power terminal (not shown) into a predetermined DC voltage required for driving the air conditioner, thereby driving each circuit and control means ( Output to 104).

Therefore, in step S1, the DC voltage output from the power supply means 100 is input from the control means 104 to initialize the air conditioner.

At this time, the user inputs the operation mode (for example, cooling), the set temperature (Ts), the set air volume of the desired air conditioner by operating the operation operation means 102, and presses the operation key, the operation operation means ( From the 102, an operation selection signal and an operation start signal (hereinafter referred to as operation signal) are input to the control means 104.

Accordingly, in step S2, the control means 104 determines whether the driving signal is input from the driving operation means 102, and if the driving signal is not input (NO), while maintaining the air conditioner in the driving standby state. The operation of step S2 or less is repeated.

As a result of the discrimination in step S2, when the operation signal is input (YES), the flow advances to step S3, and the control means 104 sends a control signal for opening the intake port 3 that is closed to the intake opening and closing drive means 114. )

Therefore, the inlet opening and closing driving means 114 is driven by the inlet motor 31 under the control of the control means 104 to drive the inlet motor 31 in the forward direction while being coupled to the shaft of the inlet motor 31 ( 32 is rotated, the slot member geared to one side of the pinion 32 is raised, the slot groove formed to be inclined to a certain degree on one side of the slide member 33 as the slide member 33 is raised ( As the 33a) is raised and the slot groove 33a is raised, the protrusion 34b of the suction grill 34 is rotated by the guide hole 35b having an arc shape, and rotates. The hinge shaft 34a formed at one side is fixed to the fixing groove 35a to form the shaft, and the suction grill 34 is rotated at an angle to open the suction port 3.

Subsequently, in step S4, the control means 104 outputs a control signal for opening the discharge port 7 which is closed to the discharge opening / closing drive means 110.

Accordingly, the discharge opening and closing drive means 110 is coupled to the shaft 22 of the discharge port motor 21 while the discharge port motor 21 is driven in the forward direction by driving the discharge port motor 21 under the control of the control means 104. The pinion 23 is rotated downward along the rack 25 to move the discharge port door 13 coupled with the rack 25 to open the discharge port 7.

At this time, in step S5 the position of the discharge port door 13 moved downward by the drive of the discharge port motor 21 is sensed by the discharge opening and closing detection means 112, the image is driven by the drive of the suction port motor 31 The rising position of the slide member 33 moving in the direction is detected by the inlet opening detecting means 116.

Accordingly, the control means 104 determines whether the discharge port door 13 and the suction grill 34 are opened by receiving the signals sensed by the discharge opening / closing detecting means 112 and the suction opening opening detecting means 116. If the discharge door 13 and the suction grill 34 are not opened (NO), the flow returns to step S3 and the discharge port motor 21 and the suction port motor are opened until the discharge door 13 and the suction grill 34 are opened. Continue to drive (31).

As a result of the discrimination in step S5, when the discharge port door 13 and the suction grill 34 are opened (YES), the flow proceeds to step S6 and the discharge opening / closing driving means 110 discharges the opening according to the control of the control means 104. The opening of the discharge port door 13 is completed by stopping the driving of the motor 21, and the suction opening / closing drive means 114 stops the driving of the suction port motor 31 under the control of the control means 104 to draw the suction grille. The opening operation of 34 is completed.

When the discharge port door 13 and the suction grille 34 are completely opened, in step S7 it is determined whether the operation condition input by the operation operation means 102 is the cooling operation, and if it is not the cooling operation (NO). In step S71, the process returns to step S7 while the heating or dehumidification operation of the air conditioner is performed, and the operation of step S7 or less is repeated.

As a result of the discrimination in step S7, in the case of the cooling operation (YES), in step S8, the control means 104 generates a control signal for driving the indoor fan 41 in order to perform the cooling operation of the air conditioner. Output to the fan motor drive means 122.

Accordingly, the indoor fan motor driving means 122 drives the indoor fan 41 by controlling the rotation speed of the indoor fan motor 39 according to the set air volume.

When the indoor fan 41 is driven, the indoor air begins to be sucked into the main body 1 through the suction port 3, and at this time, the indoor temperature of the indoor air sucked through the suction port 3 is detected. Sense at the means 106.

Therefore, in step S9, the indoor temperature sensing means 106 receives the analog data of the room temperature Tr, converts it into digital, determines whether the temperature Ts set by the user is smaller than the room temperature Tr, and sets it. If the temperature Ts is not smaller than the room temperature Tr (NO), the flow returns to the step S8 and continues the operation of step S8 or below while continuously detecting the room temperature Tr.

As a result of the discrimination in step S9, when the set temperature Ts is smaller than the room temperature Tr (YES), the process proceeds to step S10, whereby the control means 104 determines the indoor temperature Tr and the set temperature Ts. The driving frequency of the compressor 121 is determined according to the difference, and a control signal for driving the compressor 121 is output to the compressor driving means 120.

Therefore, the compressor driving means 120 drives the compressor 121 according to the operating frequency determined by the control means 104.

When the compressor 121 is driven, the indoor fan 41 is driven into the main body 1 through the suction port 3 while the indoor fan 41 is driven, and the indoor air sucked through the suction port 3 is indoors. Heat is exchanged by cold air by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 37.

The air heat-exchanged by the cold air in the indoor heat exchanger 37 is moved upward and downward or left and right depending on the wind direction angles of the up and down wind vane 9 and the left and right wind vane 11 rotatably installed at the discharge port 7. Perform room cooling while adjusting.

In the cooling operation of the air conditioner as described above, in step S12, the operation key of the operation operation means 102 is turned off to determine whether the operation stop signal is input, and when the operation stop signal is not input (when NO). In step S11, the operation of step S11 or less is repeated while the cooling operation continues.

As a result of the discrimination in step S12, when the operation stop signal is input (YES), the flow advances to step S13, whereby the control means 104 supplies a control signal for stopping the compressor 121 and the indoor fan motor 39. Output to the drive means 120 and the indoor fan motor drive means (122).

Therefore, the compressor driving means 120 stops the compressor 121 under the control of the control means 104, and the indoor fan motor driving means l22 controls the indoor fan motor 39 under the control of the control means 104. ), The driving of the indoor fan 41 is stopped, and in step S14, the control means 104 outputs a control signal for closing the intake port 3 that is open to the intake opening / closing drive means 116.

Accordingly, the inlet opening and closing driving means 116 is coupled to the axis of the inlet motor 31 while the inlet motor 31 is driven in the reverse direction by driving the inlet motor 31 under the control of the control means 104. As the pinion 32 is reversely rotated, the slide member 33 geared to one side of the pinion 32 is lowered, and as the slide member 33 is lowered, the pinion 32 is inclined to one side of the slide member 33 to a certain degree. As the slot groove 33a is formed and the slot groove 33a is lowered, the protrusion 34b of the suction grill 34 is rotated by the guide hole 35b having an arc shape, and the protrusion is rotated. The hinge shaft 34a formed at one side of the 34b is fixed to the fixing groove 35a, and the suction grill 34 is rotated at a predetermined angle to close the suction port 3 as the shaft is formed.

At this time, in step S15, the closing driving time of the inlet motor 31 is counted by the control means 104, and a predetermined time (data calculated by experimenting the time required to close the suction grille, about 11.5 seconds) has elapsed. If it is determined that the predetermined time has not elapsed (NO), the flow returns to step S14, and the inlet motor 31 is continuously driven until the suction grill 34 is closed.

As a result of the discrimination in step S15, when the predetermined time has elapsed (YES), it is determined that the suction grill 34 is completely closed, and the flow proceeds to step S16, where the inlet opening / closing driving means 110 of the control means 104 Under the control, the driving of the suction port motor 31 is stopped to complete the closing operation of the suction grill 34.

Subsequently, in step S17, the control means 104 outputs a control signal for closing the discharge port 7 which is open to the discharge port opening and closing drive means 112.

Therefore, in the discharge opening and closing driving means 112 is driven to the discharge port motor 21 in the reverse direction by driving the discharge port motor 21 under the control of the control means 104 is coupled to the shaft 22 of the discharge port motor 21 Pinion (23) is linked to it is rotated upward along the rack 25 to move the discharge port door 13 coupled to the rack 25 upwards to close the discharge port (7).

At this time, in step S18 the position of the discharge port door 13 moved upward by the drive of the discharge port motor 21 is detected by the discharge opening and closing detection means 114, the control means 104, the discharge opening and closing detection means ( It is determined whether the discharge port door 13 is closed by receiving the signal sensed by 114.

As a result of the discrimination in step S18, when the discharge port door 13 is not closed (NO), the flow returns to step S17 to continue driving the discharge port motor 21 until the discharge port door 13 is completely closed, When the discharge port door 13 is closed (YES), the flow proceeds to step S19, and the discharge opening / closing drive means 112 stops driving the discharge port motor 21 under the control of the control means 104, thereby discharging the discharge door 13 Completes the closing operation.

On the other hand, the driving of the suction port motor 31 in the steps S14 to S16 and the driving of the discharge port motor 21 in the steps S17 to S19 are performed at the same time.

Subsequently, in step S20, the control means 104 maintains the air conditioner in the operation standby state until the operation signal is input again by the operation operation means 102.

At this time, in order to adjust the indoor humidity even during operation standby (driving off) of the air conditioner, in step S21, the temperature Tr of the indoor air sucked through the inlet 3 is sensed by the indoor temperature detecting means 106, and the step In S22, the humidity (Hr) of the indoor air sucked through the suction port 3 is detected by the indoor humidity detecting means 108 and output to the control means 104.

Therefore, in step S23, the control means 104 receives analog data of the indoor temperature Tr and the indoor humidity Hr sensed by the indoor temperature detecting means 106 and the indoor humidity detecting means 108 and converts them into digital. By determining the indoor humidity (Hr) relative to the room temperature (Tr) to determine whether the humidification operation conditions.

Humidification operation condition means that the indoor humidity (Hr) is calculated and stored according to the room temperature (Tr) to maintain the room humidity (Hr) appropriate for the room temperature (Tr). Humidity (Hr) data.

If the result of the discrimination in step S23 is not a humidification operation condition (NO), no humidification is performed indoors. Therefore, the operation returns to step S20 and the operation of step S20 or less is repeated while maintaining the operation standby state of the air conditioner. In the case of the humidifying operation condition (YES), the inlet port 3 and the outlet port 7 must be opened in order to humidify the room, and the flow proceeds to step S24 where the control means 104 is closed. The control signal for opening the output to the inlet opening and closing drive means (114).

Therefore, the inlet opening / closing drive means 114 opens the inlet port 3 by driving the inlet motor 31 under the control of the control means 104, and in step S25 the control means 104 closes the discharge port 7. ) Is output to the discharge opening and closing driving means (110).

Accordingly, in the discharge opening / closing driving means 110, the discharge port 7 is opened by driving the discharge port motor 21 under the control of the control means 104. In step S26, the discharge port motor 21 is driven by driving the discharge port motor 21. The position of the discharge opening door 13 moved in the direction is detected by the discharge opening and closing detecting means 112, and the suction opening opening detection of the rising position of the slide member 33 moving upward by the driving of the suction opening motor 31. Sense at the means 116.

Accordingly, the control means 104 determines whether the discharge port door 13 and the suction grill 34 are opened by receiving the signals sensed by the discharge opening / closing detecting means 112 and the suction opening opening detecting means 116. If the discharge door 13 and the suction grill 34 are not opened (NO), the flow returns to step S24 and the discharge port motor 21 and the suction port motor are opened until the discharge door 13 and the suction grill 34 are opened. Continue to drive (31).

As a result of the discrimination in step S26, when the discharge port door 13 and the suction grill 34 are opened (YES), the flow advances to step S27 and the discharge opening / closing driving means 110 discharges the opening according to the control of the control means 104. The opening of the discharge port door 13 is completed by stopping the driving of the motor 21, and the suction opening / closing drive means 114 stops the driving of the suction port motor 31 under the control of the control means 104 to draw the suction grille. The opening operation of 34 is completed.

When the discharge port door 13 and the suction grill 34 are completely open, the control means 104 drives the indoor fan 41 and the humidifier 125 to proceed to step S28 to perform a humidification operation for humidifying the room. The control signal for outputting to the indoor fan motor driving means 122 and the humidifier driving means 124 and at the same time by turning on the humidification lamp through the display means 126 to display the humidification operation status.

Therefore, the indoor fan motor driving means 122 drives the indoor fan 41 by controlling the rotation speed of the indoor fan motor 39 under the control of the control means 104, and the humidification driving means 124 is a control means. By driving the humidifier 125 according to the control of 104, water vapor generated in the humidifier 125 is ejected into the room according to the rotation of the indoor fan 41 to perform a humidification operation of increasing indoor humidity.

At this time, in step S29, the indoor humidity Hr that changes during the humidification operation is sensed to determine whether the indoor humidity Hr maintains the appropriate humidity relative to the room temperature Tr, and when it is not the proper humidity (NO) It is determined that the indoor humidity Hr is not the proper humidity, and the flow returns to the step S28, and the operation of the step S28 or less is repeated while the indoor fan 41 and the humidifier 125 are continuously driven.

As a result of the determination in step S29, in the case of proper humidity (YES), it is determined that the indoor humidity Hr is maintained at the proper humidity, and the flow proceeds to step S30, whereby the control means 104 controls the indoor fan 41 and the humidifier 125. The control signal for stopping () is output to the indoor fan motor driving means 122 and the humidifier driving means 124 and the humidification lamp is turned off through the display means 126 to display the humidification completion state.

Therefore, the indoor fan motor driving means 122 stops the driving of the indoor fan 41 by stopping the indoor fan motor 39 under the control of the control means 104, and the humidifying driving means 124 controls the control means ( By stopping the humidifier 125 according to the control of 104, the steam is no longer generated, and the humidification operation is stopped. At step S31, it is determined whether the humidification operation stop signal is input by turning off the humidification operation key of the operation operation means 102. When the humidification operation stop signal is not input (NO), the flow returns to the step S14, closes the discharge port door 13 and the suction grill 34, and enters the operation standby state. do.

As a result of the discrimination in step S31, when the humidification operation stop signal is input (YES), the flow advances to step S32, and the control means 1004 receives a control signal for closing the inlet 3, which is open, by the inlet opening and closing drive means. Output to 116.

Accordingly, the inlet opening and closing driving means 116 is coupled to the axis of the inlet motor 31 while the inlet motor 31 is driven in the reverse direction by driving the inlet motor 31 under the control of the control means 104. As the pinion 32 is reversely rotated, the slide member 33 geared to one side of the pinion 32 is lowered, and as the slide member 33 is lowered, the pinion 32 is inclined to one side of the slide member 33 to a certain degree. As the slot groove 33a is formed and the slot groove 33a is lowered, the protrusion 34b of the suction grill 34 is rotated by the guide hole 35b having an arc shape, and the protrusion is rotated. The hinge shaft 34a formed at one side of the 34b is fixed to the fixing groove 35a, and the suction grill 34 is rotated at a predetermined angle to close the suction port 3 as the shaft is formed.

At this time, in step S33, the closing driving time of the inlet motor 31 is counted by the control unit 104, and a predetermined time (data calculated by experimenting the time required for closing the suction grill, about 11.5 seconds) has elapsed. If it is determined that the predetermined time has not elapsed (NO), the flow returns to step S32, and the inlet motor 31 is continuously driven until the suction grill 34 is closed.

As a result of the discrimination in step S33, when the predetermined time has elapsed (YES), it is determined that the suction grill 34 is completely closed, and the flow proceeds to step S34, where the inlet opening and closing driving means 110 Under the control, the driving of the suction port motor 31 is stopped to complete the closing operation of the suction grill 34.

Subsequently, in step S35, the control means 104 outputs a control signal for closing the discharge port 7 which is open to the discharge port opening and closing drive means 112.

Therefore, in the discharge opening and closing driving means 112 is driven to the discharge port motor 21 in the reverse direction by driving the discharge port motor 21 under the control of the control means 104 is coupled to the shaft 22 of the discharge port motor 21 Pinion (23) is linked to it is rotated upward along the rack 25 to move the discharge port door 13 coupled to the rack 25 upwards to close the discharge port (7).

At this time, in step S36 the position of the discharge port door 13 moved upward by the drive of the discharge port motor 21 is detected by the discharge opening and closing detection means 114, the control means 104, the discharge opening and closing detection means ( It is determined whether the discharge port door 13 is closed by receiving the signal sensed by 114.

As a result of the discrimination in step S36, when the discharge port door 13 is not closed (NO), the flow returns to step S35 to continue driving the discharge port motor 21 until the discharge port door 13 is completely closed, When the discharge port door 13 is closed (YES), the flow advances to step S37, and the discharge opening / closing drive means 112 stops driving the discharge port motor 21 under the control of the control means 104, thereby discharging the discharge door door 13. Completes the closing operation.

Subsequently, in step S38, the control means 104 returns to the step S2 while repeatedly maintaining the air conditioner in the operation standby state until the operation signal is input again by the driving operation means 102, and repeats the operation of step S2 or less. do.

According to the humidity control apparatus and method of the air conditioner according to the present invention as described above, even when the operation is off, the room temperature (Tr) and the room humidity (Hr) is sensed by the humidification operation conditions automatically run humidification operation Therefore, the indoor humidity (Hr) can be kept constant, and the automatic humidification operation can be arbitrarily released by a simple key operation, so that the user's satisfaction with the product can be satisfied.
