As shown in Figure 9, the wind direction of the air-conditioning wind that the left and right sides blade 52 by air conditioner 10 blows out is normally towards the initial position in the front of indoor unit 12 (below be referred to as " initial position C ").52 in left and right sides blade is that swing in the scope of angle θ o at the center with this initial position C.In addition, but the original position of an end of the hunting range of left and right sides blade 52 is changed to O, and left and right sides blade 52 is the setting that benchmark carries out set positions and hunting range with this original position O.Moreover initial position C is that the direction for left and right sides blade 52 original position O is the position of θ c.
In indoor unit 12, normal open is set in initial position C with wind direction, and then initially putting C with this when left and right sides blade 52 begins to swing is that swing at the center.Again, under the state of the microcomputer 74 of indoor unit 12 when the set positions switch 146 of sub remote controller 140 is set in " central authorities ", just making blade when sub remote controller 140 is connected is that the center begins swing with C.
On the other hand, in indoor unit 12, when the set positions switch 140 of sub remote controller 140 is set in " left side " or " right side ", just with the initial position setting of left and right sides blade 52 in initial position R or initial position L.In addition, the hunting range of left and right sides blade 52 then changes according to this left and right sides initial position.
That is, left and right sides blade 52 just is set at initial position R (from the angle θ of original position O when the set positions switch 140 of sub remote controller 140 is set in " left side "
R), and when being set in " right side ", then be set in position L (from the angle θ of original position O
L).Simultaneously, in indoor unit 12, making left and right sides blade 52 is being center angle θ to the left and right with initial position R, L respectively
1Swing in the scope of (for example about 30 °).
In addition, in air conditioner 10, when swinging with the change wind direction, then air quantity is proofreaied and correct in left and right sides blade according to the direction of left and right sides blade.Can realize by swing speed that changes left and right sides blade 52 or the revolution that changes cross flow fan 44 though this air quantity is proofreaied and correct, be that example illustrates with the revolution that changes (correction) cross flow fan 44 mainly in the following description.
Figure 11 illustrates the block diagram that carries out function that the revolution of cross flow fan 44 is proofreaied and correct according to the swing of left and right sides blade 52.
In control substrate 58, be provided with air quantity setting section 164 and the wind direction setting section 166 that constitutes by microcomputer 74 grades.Setting operation according to master remote controller 120 in wind direction setting section 166 reaches the signal of deciding switch 146 from the position of sub remote controller 140, and the initial position and the hunting range of left and right sides blade 52 is set.Set the result according to this, the sliding-vane motor drive part 168 that is formed by not shown driver drives left and right sides sliding-vane motor 77.Left and right sides blade 52 is fixed in the position of the angle θ that is set by wind direction setting section 166, and swings along with the variation of time according to the angle θ that is set by wind direction setting device 166 by the driving of left and right sides sliding-vane motor 77.
On the other hand, in air conditioner 10, the operation by master remote controller 120 makes three phase change of the revolution of cross flow fan 44 by H, M, L.Then change from the air quantity of the air-conditioning wind that blow-off outlet 52 blew out of indoor unit 12 according to the revolution of this cross flow fan 44.In air conditioner 10, during the automatic setting air quantity, just set the revolution of cross flow fan 44 according to room temperature and design temperature etc. by the operation of master remote controller 120 again.In view of the above, the air-conditioning wind according to the air quantity of indoor air-conditioning state just blows out from the blow-off outlet 50 of indoor unit 12.
In air quantity setting section 164, set the actuation step of fan motor 76, make beam wind fan 44 can obtain selected air quantity or the air quantity that sets.
Again, be provided with air quantity correction portion 170 in control in the substrate 58, output to by drive circuit 68 formed fan motor drive parts 172 by air quantity correction portion 170 according to the signal of the actuation step of the fan motor 76 that sets by air quantity setting section 164.In this air quantity correction portion 170, be connected with corrected value storage area 174, in order to storage according in leaf position, the left and right sides (angle θ) that wind direction setting section 166 sets and corresponding to the corrected value of the actuation step of the fan motor 76 of this angle θ.
In air quantity correction portion 170, angle θ according to the left and right sides blade of being imported from wind direction setting section 166 52, read corrected value from corrected value storage area 174, to proofread and correct the actuation step of the fan motor 76 that sets at air quantity setting section 164 corresponding to this angle θ.Fans drive part 172 is come fan motor 76 according to the actuation step of being proofreaied and correct in air quantity correction portion 170.In view of the above, cross flow fan 44 is according to the air quantity that is set by air quantity setting section 164, and the revolution after proofreading and correct according to the direction of left and right sides blade 52 is driven in rotation.
For example, the actuation step number with fan motor 76 in air conditioner 10 is set at 256 steps, selects number of steps 164 of wind direction setting sections according to air quantity.And, in fan motor 172, according to the number of steps of being imported and output voltage (for example, the voltage in 12V～36V scope), so 76 of fan motors are to be driven in rotation corresponding to the revolution of this voltage.
As shown in Figure 4, in the control substrate 58 of indoor unit 12, be provided with adopted EEPRAM etc. memory 176 as corrected value storage area 174.Angle θ according to left and right sides blade 52 in this memory 176 writes, stores with this angle θ corresponding corrected value.
Shown in Figure 12 (B), be recorded in the corrected value in the memory 176, for example, can be according to the angle of left and right sides blade 52 angle θ than initial position C
cLittle (original position O side, θ＜θ
c), or than the angle θ of initial position C
c(opposite side of original position O, θ＞θ greatly
c) and the revolution of increase cross flow fan 44.
In view of the above, shown in Figure 12 (A), the wind direction of the air-conditioning wind that is blown out according to the blow-off outlet 50 from indoor unit 12 changes air quantity.That is, with respect to air quantity, when the wind direction that blows out wind then increases its air quantity during towards original position O or towards the opposite side of original position O gradually towards the air-conditioning wind that the front blew out of indoor unit 12.Moreover, in Figure 12 (A),, and represent the size variation of air quantity with the length of arrow with the direction indication wind direction of arrow.
The below effect of explanation present embodiment.
In air conditioner 10, when operating running/stop button under the set condition of having set cold air operation, dehumidifying running or heating installation running by the switching manipulation of master remote controller 120, it just begins the pattern entry into service with said setting.
When operating air conditioner machine 10 beginning operation of air conditioner, just measure design temperature and indoor temperature, set the operating frequency, air quantity (revolution of cross flow fan) of compressor 26 etc. according to the result of this mensuration, carry out operation of air conditioner according to the result who sets.In addition, the operation mode that basis sets in outdoor unit 14 is to switch cross valve 24.
For example, when air conditioner 10 is set to cold air or dehumidification mode, flows through outdoor heat exchanger 30 by 26 refrigerant compressed of compressor and supply to the heat exchanger 18 of indoor unit 12.Like this, the cold-producing medium of supplying with the heat exchanger 18 of indoor unit 12 is gasified by heat exchanger 18 time, thereby will be by the air cooling of heat exchanger 18.Like this, blow out through heat exchanger 18 and the air after being cooled and as air-conditioning wind from the blow-off outlet 50 of indoor unit 12, thereby to being carried out cold air conditioner or dehumidifying in the air conditioning chamber 162.
On the other hand, when air conditioner 10 was set to the heating installation pattern, the high-pressure refrigerant after being compressed by compressor 26 was fed into the heat exchanger 18 of indoor unit 12.Like this, with the air heat of the heat exchanger 18 of the indoor unit 12 of flowing through.Blow out from blowing out 50 at these heat exchanger 18 heated air, in view of the above, to being carried out heating air conditioner in the air conditioning chamber 162.
Usually, air conditioner 10 blows out air-conditioning wind towards primary territory 162A, but be set at wind direction under the state of " automatically " according to left and right sides blade 52, when sub remote controller 140 is connected, when this sub remote controller 140 has been imported the set condition of configuration switch 146, then can in fixed scope, make blade 52 swings in the left and right sides with this position of beginning most by the center simultaneously according to the initial position that changes left and right sides blade 52 from the letter of this sub remote controller 140.In view of the above, when primary territory 162A is carried out air-conditioning also can to installed sub remote controller 140 near secondary field 162B carry out air-conditioning.
In addition, in indoor unit 12, when swing left and right sides blade 52 when changing the wind direction of the air-conditioning wind that is blown out from blow-off outlet 50, then proofread and correct the revolution of cross flow fan 44 according to the position (with respect to the angle θ of original position O) of left and right sides blade 52.
The flow chart of Figure 13 shows an example of the revolution of proofreading and correct cross flow fan 44.
In this flow chart, in initial step 200, confirm the correction of the revolution of cross flow fan 44, whether confirm promptly that the wind direction of the air-conditioning wind that blown out according to the blow-off outlet 50 from indoor unit 12 is proofreaied and correct.Here, for example, when the wind direction according to blade 52 is set to " automatically ", then according to carrying out air-conditioning when making 52 swings of left and right sides blade to primary territory 162A and secondary field 162B from the signal of secondary remote control machine 140, according to the angle θ of left and right sides blade 52 revolution of cross flow fan 44 is proofreaied and correct (in the sure judgement of step 200), so, enter step 202.
On the other hand, in air conditioner 10, when wind direction is set to " automatically " when making left and right sides blade 52 swing, wind direction setting section 166 (microcomputer 74) changes angle θ according to the process of time setting.Change according to this angle θ drives left and right sides sliding-vane motor 77, so left and right sides blade 52 just comes and goes in the scope that sets and moves (swing).
In addition, in air conditioner 10, select air quantity, or when air quantity is set at " automatically " by the operation of master remote controller 120, just according to indoor temperature and design temperature etc. to set from blowing out 50 air quantity that blow out.In air quantity setting section 164, according to the air quantity of selected air quantity or setting to set the actuation step of fan motor 76.
In flow chart shown in Figure 13, at first, read the actuation step X of the fan motor 76 that sets by air quantity setting section 164 in step 202
0Read in the angle θ of the left and right sides blade 52 that sets by wind direction setting section 166 then in step 204; Then, read corrected value x at next step 206 from memory 176 corresponding to the angle θ of the left and right sides blade 52 that is read in.
Then, in step 208, according to the angle θ of left and right sides blade 52 and X to setting by air quantity setting section 164
0Proofread and correct, and the rapid moving step X after the setting correction.
Like this, the signal of the actuation step X after proofreading and correct according to the angle θ of left and right sides blade 52 just is output to fan motor drive part 172.Come fan motor 76 at fan motor drive part 172 according to the actuation step X after calibrated.In view of the above, along with left and right sides blade 52 increases with respect to the inclination towards the initial position C in the front of indoor unit 12, just increase the revolution of cross flow fan 44, the air quantity of the air-conditioning wind that blows out from blow-off outlet 50 corresponding to the increase of this revolution is also along with increase.
Usually, be formed at the passage of the air-conditioning wind in the shell 42 of indoor unit 12 owing to be configured near blow-off outlet 52 blade up and down 54 and left and right sides blade 52, the particularly inclinations of left and right sides blade 52 and change.For example, when the direction of left and right sides blade 52 during near initial position C, near blow-off outlet 50 wind path impedance is lower, but when the direction of left and right sides blade 52 was pointed to the opposite side of original position O side or original position O, 52 in left and right sides blade became impedance and air quantity is descended.
To this, in air conditioner 10, the revolution that increases cross flow fan according to the angle θ of left and right sides blade 52 to be to proofread and correct, like this, even the air quantity of the air-conditioning wind that is blown out from blow-off outlet 50 is reduced owing to the inclination of left and right sides blade 52 increases the ventilation impedance.
In addition, when the wall that this indoor unit 12 is installed from the front of indoor unit 12 leaves (angle of left and right sides blade 52 is near original position O, or with original position O opposite side away from direction), wish that the field of air conditioning majority is the field away from indoor unit 12.At this moment, identical as the air quantity of air-conditioning wind, then will descend, thereby can not obtain desirable air-conditioning ability at air quantity away from the air-conditioning wind of the position of indoor unit 12.
For this, shown in Figure 12 (A) and Figure 12 (B), by setting compensating value x, increase the air quantity of the air-conditioning wind that is blown out from blow-off outlet 50 according to the angle θ (blow-off direction of air-conditioning wind) of left and right sides blade 52, proofreading and correct, thereby can enlarge the field that is in comfortable air-conditioning state.
Also have, under the form of present embodiment, the angle θ according to left and right sides blade 52 when making 52 swings of left and right sides blade increases air quantity, but also left and right sides vanes fixed can proofreaied and correct air quantity according to the angle of left and right sides blade 52 during in direction arbitrarily.In view of the above, can prevent the decline of the air-conditioning ability that causes owing to the blow-off direction that changes the air-conditioning wind that blows out from blow-off outlet 50.
Moreover, corrected value corresponding to the angle θ of left and right sides blade 52, can in memory 176, write a plurality of figures, then according to being selected by shape of air-conditioning 162 etc., preferably will be corresponding to by in the desirable figure write memory 176 of shape of air conditioning chamber 162 etc.
For example, shown in Figure 14 (A), slightly be " L " font by air conditioning chamber 162, and secondary field 162B leaves further under the situation of indoor unit 12 than primary territory 162A.At this moment, shown in Figure 14 (B) will according to about the corrected value of angle θ of sheet 52 more a step increases (bigger than the corrected value shown in Figure 12 (B)).
In view of the above, in the air-conditioning wind during to secondary field 162B owing to increased air quantity, so even secondary field leave indoor unit 12 far also can make it have with near the roughly the same air-conditioning state of the primary territory 162A of indoor unit 12.
Again,, be not limited to this, also can adopt the method that changes swing speed though be the revolution that increases cross flow fan 44 as the method that when left and right sides blade 52 is swung, increases the air quantity of air-conditioning wind in the present embodiment.That is, also can change air quantity by the swing speed that changes left and right sides blade 52.
Near first position C, the swing speed (variable quantity of the gradient of unit interval) of left and right sides blade 52 is set at left and right sides blade 52 swing speed when being slower than that left and right sides blade 52 is big to tilt.Like this, also can change the air balance that is blown out from blow-off outlet 50, thereby make wide spectrum keep certain haply air-conditioning state.
Embodiment discussed above limits formation of the present invention.The present invention is applicable to being provided with the air conditioner that is carried out any formation of air-conditioning by the air conditioning chamber of indoor unit.
As mentioned above, according to the present invention, owing to be the air quantity of proofreading and correct air-conditioning wind according to the direction of left and right sides blade, so, no matter the blow-off direction of air-conditioning wind how, also can blow out suitable air quantity and carries out air-conditioning.Also have, in the present invention, owing to will be stored in the storage device according to the air quantity corrected value of the blow-off direction of air-conditioning wind, so can be according to air quantity being proofreaied and correct, so can obtain to make wide spectrum to reach the excellent results of comfortable air-conditioning state by the shape in the air conditioning chamber.
