8A to 8C are flowcharts showing the operation procedure of the air freshener driving control of the air conditioner according to the present invention. In Figs. 8A to 8C, S indicates a 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 source 301 into a predetermined DC voltage necessary for driving the air conditioner, thereby driving each circuit and control means 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, the user operates the operation operation means 302 to input the desired operation mode (automatic, cooling, dehumidification, blowing, heating, etc.) and the set temperature (Ts) of the air conditioner, and then press the operation key, the operation operation From the means 302, an operation selection signal and an operation start signal (hereinafter referred to as an operation signal) are input to the control means 304.

Accordingly, in step S2, the control means 304 determines whether the operation key of the operation operation means 302 is on, and maintains the air conditioner in the operation standby state when the operation key is not on (NO). The operation of step S2 and below is repeated.

As a result of the discrimination in step S2, when the operation key is turned on (YES), the flow advances to step S3, whereby the control means 304 opens a high level through the output terminal P1 so as to open the inlet 3 which is closed. level) is output to the inlet opening and closing drive means 308.

Therefore, the high level open control signal output from the output terminal P1 of the control means 304 is inverted to a low level through the inverter IC 309, and the power supply means 300 The relay RY1 is driven by the DC voltage 12V output from the circuit, and the contact RY1c of the relay RY1 is closed.

When the contact RY1c of the relay RY1 is closed, in step S4, an AC voltage is applied from the AC power supply terminal 301 to the winding 141a of the inlet motor 141 to drive the inlet motor 141 in the forward direction. The pinion 142 is rotated, and simultaneously rotates another pinion 142 fixed to the other end by the rotation shaft 143, the pinion 142 is a rack gear portion formed on the lower end of the pair of slider members 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 150 are moved through the guide hole 123 of the guide member 120 while being moved simultaneously in the downward direction of the plurality of inlet doors 160 inserted into the slot holes 152. Towing the second 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 surfaces of the suction inlet door 160. The area of (3) is opened.

At this time, the auxiliary slider member 170 installed so as to move up and down linearly 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 the state not leaving the slot hole 152 of the slider member 150, During the ascending operation of the slider member 150, the second hinge shaft 162 and the slot hole 152 are recombined to prevent the malfunction of the uppermost suction port door 160 in advance.

Subsequently, in step S5, the inlet opening detecting means 310 detects the rising position of the slide member 150 moving upward by the driving of the inlet motor 141, and the inlet opening detecting means is controlled by the control means 304. 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 S4 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 S5, when the inlet door 160 is opened (YES), the flow proceeds to step S6, 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 moder 25 under the control of the control means 304 in step S7. .

When the indoor fan 23 is driven, the indoor air starts to be sucked into the main body 1 through the suction port 3, and at this time, the indoor temperature of the indoor air suctioned through the suction port 3 is detected. Sense at the means 306.

Accordingly, in step S8, 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 sensing means 306 is smaller than the temperature Ts set by the user.

As a result of the discrimination in step S8, if it is not the driving condition of the compressor 317 (NO), the flow returns to the step S7 and repeatedly performs the operation of step S7 or below while continuing to detect the room temperature Tr. In the case of the driving condition of the compressor 317 (YES), the control means 304 determines the operation frequency of the compressor 317 according to the difference between the room temperature Tr and the set temperature Ts. The control signal for driving 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 exchanges heat. 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 S11, it is determined whether the first spray key of the driving operation means 302 is turned on. If the first spray key is turned on (YES), the process proceeds to step S12. It is determined whether the second jet key of the driving operation means 302 is on.

As a result of the discrimination in step S12, when the second injection key is turned on (YES), the flow advances to step S13, whereby the control means 304 is filled in the first and second fragrance containers 230 and 240 in the main body 1. The high level first and second injection control signals are outputted to the valve driving means 312 through the output terminals P3 and P4 so as to simultaneously spray two different fragrances.

Accordingly, the high level first and second injection control signals output from the output terminals P3 and P4 of the control unit 304 are inverted to a low level through the inverter IC 313. The relays RY3 and RY4 are driven by the DC voltage 12V output from the power supply means 300 to close the contacts RY3c and RY4c of the relays RY3 and RY4.

When the contacts RY3c and RY4c of the relays RY3 and RY4 are closed, an AC voltage is applied from the AC power supply terminal 301 to the first and second solenoid valves 210 and 220 in step S14, so that the first and second solenoids are closed. The valves 210 and 220 simultaneously operate on, so that the plungers 211 and 221 move downwards, and the free ends of the first and second fragrance containers 230 and 240 fixed to the rear of the guide member 120 via the bracket 250. Press cover (232,242).
