The control signal is input to control the rotational speed of the fan motor 15 to drive control the indoor fan 11 and the outdoor fan 13 and the display means 116 is driven according to the control of the control means 104 The operation means 102 displays the operation condition and the set temperature Ts set by the user, as well as the operation state of the air conditioner.

Hereinafter, the operation of the inlet opening and closing device of the air conditioner and the method configured as described above will be described.

7 (a) and 7 (b) are flow charts showing the intake opening and closing control operation procedure of the air conditioner according to the present invention, where S is a step in FIGS. 7 (a) and 7 (b). (STEP) is displayed.

As an initial condition for explaining the operation of the present invention, it is assumed that the outdoor air intake opening 38a is 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, when the user operates the operation operation means 102 and inputs a desired operating condition (cooling, cleaning, dehumidification, etc.) and a set temperature Ts of the air conditioner, and then turns on the operation key, the operation operation means 102 ) And an operation start signal (hereinafter referred to as an 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 maintains the air conditioner in the operation standby state when the driving signal is not input (NO). The operation below Step S2 is repeatedly performed.

As a result of the discrimination in step S2, when the operation signal is input (YES), the control means 104 proceeds to step S3 and the control means 104 opens a control signal for opening the closed outdoor air intake opening 38a by the motor driving means ( 108).

Accordingly, in the motor driving means 108, the pinion gear 57 coupled to the shaft 55a of the driving motor 55 is driven in a predetermined direction by driving the driving motor 55 under the control of the control means 104. As it rotates, the pinion gear 57 and the rack gear 59 engaged with the pinion gear 57 move to the left side along the guide grooves 51a and 52a toward the interior side 3.

Accordingly, the opening and closing panel 61 coupled with the rack gear 59 is moved to the left to open the outdoor air suction opening 38a. At this time, the roller member 63 provided on the lower side of the opening and closing panel 61 moves along the guide rail 65.

When the rack gear 59 is moved as described above to open the outdoor air intake opening 38a, in step S4, the opening / closing panel 61 moved to the left by the first opening / closing sensor 67 installed at one end of the guide groove 51a. ), And the control means 104 receives the signal detected by the first opening / closing sensor 67 to determine whether the outdoor air intake opening 38a is completely open.

As a result of the discrimination in step S4, when the outdoor air intake opening 38a is not completely opened (NO), the drive motor 55 is continued until the open / close panel 61 is completely opened. If the outdoor air suction opening 38a is completely opened (YES), the motor driving means 108 stops driving the driving motor 55 under the control of the control means 104. The opening operation of the opening and closing panel 61 is completed.

Subsequently, in step S6, the fan motor driving means 114 controls the rotation speed of the fan motor 15 under the control of the control means 104 to drive the indoor fan 11 and the outdoor fan 13.

When the indoor fan 11 is driven, the indoor air begins to be sucked into the air conditioner 1 through the suction grill 23, and at this time, the temperature Tr of the indoor air sucked through the suction grill 23. Is sensed by the indoor temperature detecting means (106).

Accordingly, in step S7, the indoor temperature Tr sensed by the indoor temperature sensing means 106 is compared with the temperature Ts set by the user to the operation operation means 102, thereby applying the driving condition of the compressor 17. Determine.

The driving condition of the compressor 17 refers to a case in which the room temperature Tr sensed by the room temperature sensing means 106 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 106 is smaller than the temperature Ts set by the user.

As a result of the discrimination in step S7, when it is not the driving condition of the compressor 17 (NO), the process returns to the step S6 and repeatedly performs the operation of step S6 or less while continuously detecting the room temperature Tr, In the case of the driving condition of the compressor 17 (YES), the control means 104 determines the operating frequency of the compressor 17 according to the difference between the room temperature Tr and the set temperature Ts. The control signal for driving the compressor 17 is output to the compressor driving means 112.

Therefore, the compressor driving means 112 drives the compressor 17 according to the operating frequency determined by the control means 104.

When the compressor 17 is driven, in step S9 the refrigerant compressed by the compressor 17 into gas of high temperature and high pressure is the solid line of FIG. As shown by), it is introduced into the outdoor heat exchanger (35) installed on the outdoor side (5), at which time the indoor air according to the rotation of the indoor fan (11) the suction port (23a) of the suction grill (23) The indoor air sucked through the suction port 23a passes through the indoor heat exchanger 27 after the foreign matter is filtered through the filter member 25.

As the outdoor fan 13 rotates, outdoor air is sucked in through the outdoor air intake port 38a of the cover member 38 as indicated by arrow B of FIG. The outdoor air sucked into the air cools the refrigerant flowing in the outdoor heat exchanger 35 while passing through the outside of the fan motor 15 and the outdoor heat exchanger 35, and at the same time, the compressor 17 and the fan motor 15. After cooling, it is discharged to the outside through the outlet (39a) of the back plate (39).

At this time, the outdoor air suction opening 38a increases the cooling amount of the compressor 17 and the outdoor heat exchanger 35 by increasing the suction amount of the outdoor air by forming a wide opening formed by the square hole.

Accordingly, in the outdoor heat exchanger 35, the gas refrigerant compressed by the compressor 17 at high temperature and high pressure is exchanged with air blown by the outdoor fan 13 to liquefy the refrigerant to be liquefied, and the outdoor heat exchanger ( The low temperature and high pressure liquid refrigerant liquefied in 35 is passed through an expansion valve 43 which expands to the evaporation pressure and decompressed into a low temperature low pressure free refrigerant and flows into the indoor heat exchanger 27.

Accordingly, in the indoor heat exchanger (27), when the low-temperature low-pressure free refrigerant reduced in the expansion valve (43) evaporates and vaporizes through a plurality of pipes, the heat is removed from the air blown by the indoor fan (11). Cool the room air.

Cold air heat exchanged in the indoor heat exchanger (27) is introduced into the indoor fan (11) under the guidance of the duct member (9), and the cold air introduced into the indoor fan (11) is indicated by the arrow (A) of FIG. As shown in the drawing, while being adjusted in the vertical direction and the left and right direction by the wind direction up and down control blades 31 and the wind direction left and right control blades 33 of the discharge grill 29 to be cooled to perform the cooling.

In addition, the low-temperature low-pressure gas refrigerant cooled in the indoor heat exchanger 27 is sucked into the compressor 21 again and the solid line of FIG. As shown by), indoor cooling is performed while forming a repetitive freezing cycle.

When the user turns off the operation key during the cooling operation of the air conditioner as described above, an operation stop signal is input from the operation operation means 102 to the control means 104.

Therefore, in step S10, the operation stop signal 102 determines whether the operation stop signal has been input to the control means 104, and when the operation stop signal is not input (NO), returns to the step S9 and cools the operation. Continue to run

As a result of the discrimination in step S10, when the operation stop signal is input during the cooling operation (YES), the flow advances to step S11 and the control means 104 stops the compressor 17 and the fan motor 15. Is output to the compressor driving means 112 and the fan motor driving means (114).

Accordingly, the compressor driving means 112 stops the compressor 17 under the control of the control means 104, and the fan motor driving means 114 controls the fan motor 15 under the control of the control means 104. ), The driving of the indoor fan 11 and the outdoor fan 13 is stopped.

Subsequently, in step S12, the control means 104 outputs a control signal to the motor driving means 108 for closing the open discharge port 4.

Accordingly, in the motor driving means 108, the pinion gear 57 coupled to the shaft 55a of the driving motor 55 is driven in a predetermined direction by driving the driving motor 55 under the control of the control means 104. As it rotates, the pinion gear 57 and the rack gear 59 engaged with the pinion gear 57 move to the right side toward the outdoor side 5 along the guide grooves 51a and 52a.

Accordingly, the opening and closing panel 61 coupled with the rack gear 59 is moved to the right to close the outdoor air suction opening 38a.

When the rack gear 59 is moved to close the outdoor air suction opening 38a as described above, the opening / closing panel 61 moved to the right by the second opening / closing sensor 68 installed at one end of the guide groove 52a in step S13. Position), and the control means 104 receives the signal detected by the second opening / closing sensor 68 to determine whether the outdoor air suction opening 38a is completely closed.

As a result of the discrimination in step S13, when the outdoor air intake opening 38a is not completely closed (NO), the drive motor 55 is continued until the open / close panel 61 is completely closed. If the outdoor air suction opening 38a is completely closed (YES), the motor driving means 108 stops driving the driving motor 55 under the control of the control means 104. The closing operation of the opening / closing panel 61 is completed.

Therefore, the outdoor air suction opening 38a is closed by the opening / closing panel 61, thereby preventing the inflow of dust or foreign matters, thereby preventing the performance degradation of the air conditioner.

Subsequently, in step S15, the control means 104 ends the operation while maintaining the air conditioner in the operation standby state until the operation start signal is input again by the operation operation means 102.

According to the inlet opening and closing device and the method of the air conditioner according to the present invention as described above, while increasing the intake amount of the outdoor air to increase the air conditioning effect, when the air conditioner is inactive, the dust through the outdoor air inlet B. It has an excellent effect of preventing foreign matter from entering.
