Hereinafter, the effect of the air freshener driving apparatus and the method of the air conditioner configured as described above will be described.

8A to 8C are flow charts showing the air freshener driving control operation procedure of the air conditioner according to the present invention, in which S denotes a step (STEP).

As an initial condition for explaining the operation of the present invention, it is assumed that the inlet 3 is closed.

First, when power is applied to the air conditioner, the power supply unit 300 converts the commercial AC voltage supplied from the AC power supply terminal 301 into a predetermined DC voltage required for driving the air conditioner, thereby driving each circuit and control means ( Output to 304).

Therefore, in step S1, the DC voltage output from the power supply means 300 is received by the control means 304 to initialize the air conditioner.

At this time, in step S2, the operation operation means 302 is operated to input the operation mode (automatic, cooling, dehumidification, blowing, heating, etc.) and the set temperature Ts of the air conditioner desired by the user, Set the injection time and injection vessel to inject the fragrances of the first and second air freshener containers 230 and 240 (for example, the first air freshener container at the T1 injection time and the second air freshener container at the T2 injection time). When is pressed, an operation selection signal and an operation start signal (hereinafter referred to as an operation signal) are input from the operation operation means 302 to the control means 304.

On the other hand, if the user does not set the injection time and the injection vessel by operating the operation operation means 302 is set to the default value determined at the factory.

Accordingly, in step S3, the control means 304 determines whether the operation key of the operation operation means 302 is turned on, and maintains the air conditioner in the operation standby state when the operation key is not turned on (NO). The operation below step S3 is repeatedly performed.

As a result of the discrimination in step S3, when the operation key is turned on (YES), the flow advances to step S4, whereby the control means 304 opens a high level through the output terminal P1 so as to open the inlet 3 which is closed. The control signal of 1eve1 is outputted to the inlet opening / closing drive means 308.

Accordingly, the high level (leve1) open control signal output from the output terminal P1 of the control means 304 is inverted to the low level Low1eve1 through the inverter IC 309, and from the power supply means 300. The relay RY1 is driven by the output DC voltage 12V to close the contact RY1c of the relay RY1.

When the contact RY1c of the relay RY1 is closed, in step S5, the inlet motor 141 is driven in the forward direction by being applied from the AC power supply terminal 301 to the winding 141a of the AC voltage inlet motor 141. 142 is rotated, and simultaneously rotates another pinion 142 fixed to the other end by the rotation shaft 143, these pinions 142 is a rack gear portion formed on the lower end of the pair of slider buoy 150 ( Each of the slider members 150 is lifted up and down in contact with each other, and the slider members 150 are guided to the outer surfaces of the pair of guide members 120 to linearly move downward. The plurality of slot holes 152 formed in the first through the guide hole 123 of the guide member 120 while being moved simultaneously in the lower direction of the plurality of inlet doors 160 inserted into the slot hole 152 2 by fitting the hinge shaft 162 downward The plurality of suction inlet doors 160 are rotated around a hinge point between the hinge groove 122 formed in the guide member 120 and the first hinge shaft 161 protruding from both side lower ends of the suction inlet diagram 160. Open the area of 3).

At this time, the auxiliary slider member 170 installed to linearly move up and down by the guide part 153 formed on the outermost surface of the slider member 150 has a second hinge shaft 162 when the slide member 150 is lifted up. Ascending through the slot hole 152 by a friction action inserted into the slot groove 171 of the auxiliary slider member 170, the lifting operation is stopped at the moment when the uppermost end of the guide member 120 is reached. .

At the same time, when the slider member 150 also reaches the uppermost end of the guide member 120, the locking step (not shown) and pinion 142 formed on the lower side of the rack gear unit 151 with respect to the lower end of the slider member 150. Since the upward motion is stopped by the contact with the auxiliary slider member 170 is accommodated in the guide portion 153 and the support protrusion (not shown) of the guide portion 153 and the support groove of the auxiliary slider member 170 ( (Not shown) compresses the spring (not shown) accommodated within the gap, and the second hinge shaft 162 of the inlet door 160 is located in a state not to deviate from the slot hole 152 of the slider member 150, During the ascending operation of the slider member 150, the second hinge shaft and the slot hole are recombined to prevent the malfunction of the uppermost suction port door 160 in advance.

Subsequently, in step S6, the inlet opening detecting means 310 detects the rising position of the slide member 150 moving upward by the inlet motor 141, and the control means 304 detects the inlet opening. It is determined whether the inlet door 160 is opened by receiving the signal sensed by the means 310, and if the inlet door 160 is not opened (NO), the process returns to the step S5 and the inlet door 160 is opened. The inlet motor 141 continues to be driven until it is opened.

As a result of the discrimination in step S6, when the inlet door 160 is opened (YES), the flow proceeds to step S7 where the inlet opening / closing drive unit 308 outputs the low level output from the output terminal P1 of the control unit 304. The driving of the inlet motor 141 is stopped in accordance with the open control signal of the to complete the opening operation of the inlet door 160.

When the inlet door 160 is opened, the fan motor driving means 318 drives the indoor fan 23 by controlling the rotation speed of the indoor fan motor 25 under the control of the control means 304 in step S8. In step S9, the control means 304 counters the driving time of the indoor fan 23 by a built-in timer.

Therefore, in step S10, it is determined whether the time counted by the control means 304 has passed the injection time Tl set by the operation operation means 302, and the injection time Tl has not elapsed (NO). In step S11, it is determined whether the time counted by the control means 304 has passed the injection time T2 set by the operation operation means 302.

As a result of the discrimination in step S11, when the injection time T2 has elapsed (YES), the flow advances to step S12, whereby the control means 304 is filled in the second fragrance container 240 inside the main body 1. The second injection control signal of the high level High 1eve1 is output to the valve driving means 312 through the output terminal P4 so as to inject the air freshener.

Therefore, the second injection control signal of the high level High 1eve1 output from the output terminal P4 of the control means 304 is inverted to the low level Low level1 through the inverter LC 313, and the power supply means ( The relay RY4 is driven by the DC voltage 12V output from the 300 to close the contact RY4c of the relay RY4.

When the contact RY4c of the relay RY4 is closed, in step S13, an AC voltage is applied from the AC power supply terminal 301 to the second solenoid valve 220 so that the second solenoid valve 220 is turned on to operate the plunger ( As the 221 moves downward, the free end presses the cover 242 of the second fragrance container 240 fixed to the rear surface of the guide member 120 via the bracket 250.

Therefore, in step S14, the cover 242 of the second fragrance container 240 pumps the fragrance of one fragrance filled in the body 241 by the pressing force of the plunger 221 and at the same time, the injection formed in the cover 242. Indoor air is injected into the main body 1 by the rotational force of the indoor fan 23 by spraying a predetermined amount toward the heat exchanger 21 through the hole 242a and spraying toward the heat exchanger 21. By radially diffused by to remove the dust or foreign matter inside the main body 1 or the odor generated from the heat insulating material and mechanical properties inside the main body 1, and at the same time the discharge port with the air heat exchanged in the heat exchanger (21) 7) is discharged into the room to increase the room cleanliness.

In the fragrance spraying operation as described above, in step S15, the control means 304 counteracts the fragrance spraying time according to the on operation of the second solenoid valve 220 to remove a predetermined time (deodorization inside the product). And if the optimum air freshener spray time required for cleaning the indoor air has elapsed, and if the predetermined time has not elapsed (N0), the process returns to step S14 and the air freshener spraying operation is continued until the predetermined time elapses. The operation of step S14 or below is repeated while performing the operation.

As a result of the discrimination in step S15, when a predetermined time has elapsed (YES), the process proceeds to step S16 and the control means 304 stops the low level (Low 1 evel) through the output terminal P4 to stop the perfume injection operation. The second injection control signal is outputted to the valve drive means 312.

Therefore, the second injection control signal of the low level output from the output terminal P4 of the control means 304 is inverted to the high level High 1eve1 through the inverter IC 313, thereby relaying the relay RY4. The contact RY4c of the relay RY4 is opened while current is not induced to the relay RY4.

When the contact RY4c of the relay RY4 is opened, in step S17, the AC voltage applied to the second solenoid valve 220 from the AC power supply terminal 301 is cut off, so that the second solenoid valve 220 is turned off and the plunger ( As the 221 moves upward, the free end of pressing the cover 242 of the second fragrance container 240 is released.

Therefore, in step S18, the cover 242 of the second fragrance container 240 is transferred from the body 241 by the releasing force of the plunger 221 to stop the fragrance injection operation.

On the other hand, when the indoor fan 23 is driven, the indoor air begins to be sucked into the main body 1 through the suction port 3, at which time the temperature Tr of the indoor air sucked through the suction port 3 is indoors. The temperature sensing means 306 senses it.

Accordingly, in step S19, the indoor temperature Tr sensed by the indoor temperature detecting means 306 is compared with the temperature Ts set by the user to the operation operation means 302, thereby applying the driving condition of the compressor 317. Determine.

The driving condition of the compressor 317 is a case in which the room temperature Tr sensed by the room temperature sensing means 306 is greater than the temperature Ts set by the user during the cooling operation. The room temperature Tr sensed by the room temperature detecting means 306 is smaller than the temperature Ts set by the user.

As a result of the discrimination in step S19, if it is not the driving condition of the compressor 317 (NO), the flow returns to the step S9 and repeats the operation of step S9 or less, and is the driving condition of the compressor 317 ( If YES), the control means 304 determines the operating frequency of the compressor 317 according to the difference between the room temperature Tr and the set temperature Ts, and proceeds to step S20 to control the compressor 317. Is output to the compressor driving means (316).

Therefore, the compressor driving means 316 drives the compressor 317 according to the operating frequency determined by the control means 304.

When the compressor 317 is driven, the indoor fan 23 is driven into the main body 1 through the suction port 3 while the indoor fan 23 is driven, and the indoor air sucked through the suction port 3 is heat-exchanged. Heat is exchanged by cold air or warm air by latent heat of evaporation of the refrigerant flowing in the heat exchanger 21 while passing through the air 21.

The air heat-exchanged by cold or warm air in the heat exchanger 21 is moved upward and downward or left and right depending on the wind angles of the up and down wind vane 9 and the left and right wind vane 11 rotatably installed at the discharge port 7. The air conditioning is performed while this is controlled.

In the normal operation of the air conditioner as described above, in step S22 it is determined whether the operation key of the operation operation means 302 is turned off, and when the operation key is not turned off (N0), the operation returns to the step S21 and is normal. The operation below Step S21 is repeatedly performed while continuing operation.

As a result of the discrimination in step S22, when the operation key is turned off (YES), the flow advances to step S23, whereby the control means 304 drives the compressor to control signals for stopping the compressor 317 and the indoor fan motor 25. Output to the means 316 and the fan motor drive means (318).

Accordingly, the compressor driving means 316 stops the compressor 317 under the control of the control means 304, and the fan motor driving means 318 controls the indoor fan motor 25 under the control of the control means 304. To stop the driving of the indoor fan 23.

Subsequently, in step S24, the control means 304 outputs the control signal of the high level 1 through the output terminal P2 to the intake opening and closing drive means 308 through the output terminal P2 so as to close the intake opening 3 that is open.

Therefore, the control preference of the high level High 1eve1 output from the output terminal P2 of the control means 304 is inverted to the low level Low 1eve1 through the inverter LC 309, and from the power supply means 300. The relay RY2 is driven by the output DC voltage 12V to close the contact RY2c of the relay RY2.

When the contact RY2c of the relay RY2 is closed, in step S25, an AC voltage is applied from the AC power supply terminal 301 to the winding 141b of the inlet motor 141 so that the inlet motor 141 is driven in the reverse direction. The pinion 142 is rotated, and simultaneously rotates another pinion 142 fixed to the other end by the rotation shaft 143, these pinions 142 is a rack gear formed on the lower end of the pair of slider means 150 These slider members 150 are lowered in the state of gear contact with the part 151, respectively.

At the same time, when the slider member 150 is guided to the outer surface of the pair of guide members 120 and linearly moved upward, the plurality of slot holes 152 formed in the slider member 150 are simultaneously positioned upward. A plurality of suction doors are moved by pushing the second hinge shafts 162 of the plurality of suction door doors 160 inserted into the slot holes 152 upward through the guide holes 123 of the guide member 120. 160 are rotated around the hinge point of the hinge groove 122 formed in the guide member 120 and the first hinge shaft 161 protruding from the lower side of both sides of the inlet door 160, the area of the suction port (3) Will be closed.

At this time, the auxiliary slider member 170 installed to linearly move up and down by the guide part 153 formed on the outermost surface of the slider member 150 has a second hinge shaft 162 slotted when the slide member 150 moves downward. Through the hole 152 is lowered slowly than the lowering speed of the slider member 150 by the friction action inserted into the slot groove 171 of the auxiliary slider member 170 and the spring force (not shown), the slider member ( 150 is protruded to the outside of the top end, the slot groove 171 formed on the inner surface of the auxiliary slider member 170 is matched with the top cutout of the slot hole 152 formed on the top end of the slider member 150 Since it is positioned on the extension line, the second hinge shaft 162 of the uppermost side suction port door 160 which deviates from the effective stroke distance of the slot hole 152 during the lowering operation of the slider member 150 is restrained and the uppermost side suction port door The malfunction of the 160 is blocked beforehand.

At this time, in step S26, the closing drive time of the inlet motor 141 is counted by the control unit 304, and a predetermined time (data calculated by loading the time required for the inlet door to close, e.g., about 11.5 seconds) has elapsed. If it is determined that the predetermined time has not elapsed (NO), the flow returns to step S25 to continue driving the inlet motor 141 until the inlet door 160 is closed.

As a result of the discrimination in step S26, when a predetermined time has elapsed (YES), it is determined that the inlet door 160 is completely closed, and the flow proceeds to step S27, where the inlet opening / closing driving means 308 is The driving of the suction port motor 141 is stopped according to the low level closing control signal output from the output terminal P2 to complete the closing operation of the suction grill 34.

Subsequently, in step S28, the control means 304 returns to the step S3 while repeating the operation of step S3 while maintaining the air conditioner in the operation standby state until the operation key is turned on again by the driving operation means 302. do.

On the other hand, when the determination result in step S10 indicates that the injection time Tl has elapsed (YES), the flow advances to step S30, whereby the control means 304 fills the first fragrance container 230 inside the body 1. The first injection control signal of the high level High 1eve1 is outputted to the valve driving means 312 through the output terminal P3 so as to inject the prepared perfume.

Accordingly, the first injection control signal of the high level High 1eve1 output from the output terminal P3 of the control means 304 is inverted to the low level 1ve1 through the inverter LC 313 and the power supply means ( The relay RY3 is driven by the DC voltage 12V output from the 300 to close the contact RY3c of the relay RY3.

When the contact RY3c of the relay RY3 is closed, in step S31, an AC voltage is applied from the AC power supply terminal 301 to the first solenoid valve 210 so that the first solenoid valve 210 is turned on to operate the plunger ( While moving 211 downward, the free end presses the cover 232 of the first fragrance container 230 fixed to the rear surface of the guide member 120 via the bracket 250.

Therefore, in step S32, the cover 232 of the first fragrance container 230 pumps the fragrance of one fragrance filled in the body 231 by the pressing force of the plunger 211 and at the same time, the injection formed in the cover 232. A certain amount of fragrance sprayed toward the heat exchanger 21 through the hole 232a, and the fragrance of one direction injected toward the heat exchanger 21 is sucked into the main body 1 by the rotational force of the indoor fan 23. By radially diffused by to remove the dust or foreign matter inside the main body 1 or the odor generated from the heat insulating material and mechanical properties inside the main body 1, and at the same time the discharge port with the air heat exchanged in the heat exchanger (21) 7) is discharged into the room to increase the room cleanliness.

In the fragrance injection operation as described above, in step S33, the control means 304 counts the fragrance injection time according to the ON operation of the first solenoid valve 210 to determine whether a predetermined time has elapsed, If the time has not elapsed (NO), the flow returns to the step S32, and the operation of the step S32 or less is repeatedly performed while continuing the perfume injection operation until the predetermined time has elapsed.

As a result of the discrimination in step S33, if a predetermined time has elapsed (YES), the process proceeds to step S34, whereby the control means 304 stops the low level of the low level through the output terminal P3 to stop the perfume injection operation. The one injection control signal is outputted to the valve drive means 312.

Accordingly, the first injection control signal of the low level Low 1 evel output from the output terminal P3 of the control unit 304 is inverted to the high level 1 through 1 through the inverter IC 313 to relay RY3. The contact RY3c of the relay RY3 is opened while no current is induced in the circuit.

When the contact RY3c of the relay RY3 is opened, the AC voltage applied to the first solenoid valve 210 is cut off from the AC power supply terminal 301 at step S35 so that the first solenoid valve 210 is turned off and the plunger ( As the 211 moves upward, the free end of pressing the cover 232 of the first fragrance container 230 is released.

Therefore, in step S36, the cover 232 of the first fragrance container 230 is transferred from the body 231 by the releasing force of the plunger 211 and stops the fragrance injection operation, and proceeds to the step S19, and the operation of step S19 or less. Repeat

When the injection time T2 has not elapsed (NO) as a result of the discrimination in step S11, the flow advances to step S19 to repeat the operations of step S19 and below.
