The specific embodiment
Fig. 1, Fig. 2 represent the indoor unit of the air conditioner of this embodiment.Indoor unit comprises heat exchanger 1 and indoor fan 2, and they are installed in the shell 3.Shell 3 is made the long box-shaped of depth ratio height, and face is made flexure plane on earth from the front.Upper surface at shell 3 forms suction inlet 4, on flexure plane, forms blow-off outlet 5.
Form from suction inlet 4 to blow-off outlet 5 air duct 6 in the inside of shell 3, heat exchanger 1 is configured in this air duct 6 with indoor fan 2.Between suction inlet 4 and heat exchanger 1, dispose filter 7, be used for removing dust from the room air of suction inlet 4 suctions.And be provided with the clearing apparatus 8 that this filter 7 is cleaned.
Clearing apparatus 8 moves filter 7 in shell 3, in dust removal portion 9, remove attached to the dust on the filter 7 through dust removal portion 9.Front side in shell 3 forms and sees the guide path 10 that curves U-shaped from the side, and the moving part that is made up of motor, gear makes filter 7 move back and forth along guide path 10.In dust removal portion 9, utilize roll brush 11 to remove dust from the filter 7 that passes through, utilize drawing fan that the parallel substantially direction (left and right directions) of air edge and filter 7 is flowed, the dust that attracts to be removed and with its discharge.
The flexure plane of shell 3 is provided with the wind-guiding panel 20 of switch blow-off outlet 5.Like Fig. 3～shown in Figure 6, wind-guiding panel 20 can be opened up or down, thereby and is provided with and makes wind-guiding panel 20 move the switching device that carries out switch.
Wind-guiding panel 20 is processed the front of covering shell 3 by a panel of bending.The width of wind-guiding panel 20 is made with the width of shell 3 and equated, and is wideer than the width of blow-off outlet 5.Front at shell 3 forms front panel 21, so that become lower from the mid portion of front to the bottom surface.Thus, on whole width, form recess, in recess, embed wind-guiding panel 20.On the front panel 21 that forms recess, form opening, this opening is a blow-off outlet 5.Therefore, wind-guiding panel 20 is positioned at the place ahead than blow-off outlet 5, covers blow-off outlet 5 and blow-off outlet 5 front panel 21 on every side.At this moment, wind-guiding panel 20 is a closed condition shown in Figure 2.
When being in closed condition, between the front-end and back-end of wind-guiding panel 20 and shell 3, form the gap.Like Fig. 4, shown in Figure 6, when wind-guiding panel 20 switches, the end of wind-guiding panel 20 enters into this gap.Wind-guiding panel 20 bumps less than shell 3, can smoothly rotate.In addition, when upwards opening or open, when wind-guiding panel 20 is opened to maximum,, wind-guiding panel 20 is contacted with shell 3 downwards, thereby prevent that the wind that blows out from leaking through forming the end, front and back of wind-guiding panel 20.Particularly blowing out under the situation of cold wind, dew can prevent to condense in the bottom surface of shell 3.
The outer surface of wind-guiding panel 20 is constituted from the front of shell 3 to the smooth flexure plane of bottom surface.That is to say that wind-guiding panel 20 is the parts that constitute shell 3 a fronts part.In other words, use a part of panel of shell 3 as wind-guiding panel 20.Thus, the shutter board that adopts on wind-guiding panel 20 and in the past the air conditioner is compared, and is the long long panel of length overall.
Wind-guiding panel 20 is that middle mind-set different directions rotates through above lower shaft, and any direction is opened in above-below direction.Like Fig. 5, shown in Figure 6, wind-guiding panel 20 is opened downwards around lower shaft 22 when thermantidote turns round.When being in this posture of opening downwards, wind-guiding panel 20 links to each other with the lower wall of blow-off outlet 5, utilizes the upper wall of wind-guiding panel 20 and blow-off outlet 5 to form long spout.Wind-guiding panel 20 cold wind guiding oblique upper to, cold wind is blown out along the roof.Like Fig. 3, shown in Figure 4, when heating installation turns round around on axle 23 upwards open.When being in this posture of upwards opening, wind-guiding panel 20 shelters from the place ahead of blow-off outlet 5, pushes down the warm braw that forwards blows out, warm braw guiding ground direction.In addition,, make cold wind blow to the ground direction, carry out fast-refrigerating even, also can make wind-guiding panel 20 become the posture of upwards opening at the initial stage of cooling air unit running.As shown in Figure 2, when shutting down, become closed posture, wind-guiding panel 20 covers blow-off outlet 5, becomes one with shell 3.
In addition, in blow-off outlet 5, be provided with the auxiliary shutter board of not representing among wind direction board 24 and the figure.Wind direction board 24 changes the wind direction of left and right directions in left and right directions up conversion angle.The angle that auxiliary shutter board comes the conversion above-below direction according to the posture of wind-guiding panel 20, rectification is carried out to the wind that blows out in the limit, and the limit changes the wind direction of above-below direction.
Above-mentioned this large-scale wind-guiding panel 20 is easy to generate distortion or crooked.So on the inner surface of wind-guiding panel 20, on two end edge of fore-and-aft direction (short side direction), form the perisporium that strengthens usefulness.Perisporium spreads all over whole left and right directions (long side direction).Perisporium is a hollow structure, can be all wall thickenings.Utilize such perisporium can improve the intensity of wind-guiding panel 20, prevent bending.In addition, on two end edge of left and right directions, also form the perisporium of same enhancing usefulness.Therefore, can prevent 20 distortions of wind-guiding panel.
Like this, through make wind-guiding panel 20 around the end edge wall thickness strengthen and gain in strength, can improve the intensity of wind-guiding panel 20 resistance to deformations, thereby wind-guiding panel 20 is maximized.And because wind-guiding panel 20 is to be difficult to deformed configurations, so can make the degree of crook of the fore-and-aft direction of wind-guiding panel 20 become big, thus the air supply direction when controlling wind-guiding panel 20 easily and opening.That is to say, when thermantidote turns round, can be the cold wind roof that leads, thus can make the arrival distance of cold wind elongated.When heating installation turns round, guide warm braw with mode near wall, make warm braw arrive ground.
In addition, the front end at perisporium forms the inclined plane.The inner surface that makes perisporium is the inclined plane.Outer surface is a vertical plane.When wind-guiding panel 20 was in the posture of opening downwards, the cold wind that blows out was run into the perisporium that is positioned on the left and right directions, and dew sometimes condenses on perisporium.So, cold wind is flowed along the inclined plane through making the inclined plane.Cold wind can not stopped, thereby prevent the dew that on perisporium, condenses.
The inner surface of the wind-guiding panel 20 that is centered on by this perisporium is provided with thermal insulation barriers 30.Thermal insulation barriers 30 is installed on the total inner surface except that the left and right directions two ends.Make the width of the left and right directions of thermal insulation barriers 30 wideer than the width of blow-off outlet 5.The surface of thermal insulation barriers 30 is in same plane.Therefore, do not have protrusion, can not hinder flowing of wind in inner surface one side towards the wind-guiding panel 20 of blow-off outlet 5.
Both sides at the left and right directions of the inner surface of wind-guiding panel 20 are provided with support member 31.20 mounting or dismounting of wind-guiding panel are installed on the support member 31 freely.Support member 31 is installed on the shell 3 through bar 32.That is to say that wind-guiding panel 20 is installed on the shell 3 through bar 32, and can tear open at shell 3 enterprising luggages.
As shown in Figure 5, be provided with the pawl 33 that on left and right directions, slides freely in the left and right directions both sides of wind-guiding panel 20.Pawl 33 is relative with the perisporium that on fore-and-aft direction, forms, and utilizes spring etc. to press member and presses to perisporium.Through being clamped in support member 31 between pawl 33 and the perisporium, wind-guiding panel 20 is installed on the support member 31.Through pawl 33 is slided to the direction of leaving perisporium, take off wind-guiding panel 20 from support member 31.
On this external fore-and-aft direction, pawl 33 is arranged on a side at least and gets final product.In this case,, and in wind-guiding panel 20 or support member 31, on any one pin is set, on another, forms the hole at opposite side.Through in the pin embedded hole, wind-guiding panel 20 is engaged with support member 31.Be provided with in a side under the situation of pawl 33, consider operability, be arranged on rear side for well.In this case, the user can be under the state of opening posture downwards wind-guiding panel 20, and pawl 33 limits mounting or dismounting wind-guiding panel 20 is being seen on the limit.Therefore can easily and install and remove operation reliably, and, drop so can prevent wind-guiding panel 20 owing to can carry out operation with one hand support wind-guiding panel 20 limits in the limit.
The upward axle 23 of wind-guiding panel 20 is arranged on the front side of support member 31, and lower shaft 22 is arranged on the rear side of support member 31.Last lower shaft 22,23 supports two ends so that make lower shaft 22,23 leave support member 31 along the left and right directions configuration.Last lower shaft 22,23 is positioned on the direction than blow-off outlet 5 all around and more relies on the outside and be positioned at the position that more relies on the place ahead than blow-off outlet 5.Therefore, last lower shaft 22,23 does not influence flowing of the wind that blows out from blow-off outlet 5.
Also can make support member 31 and wind-guiding panel 20 integrated.Bar 32 is directly installed on the wind-guiding panel 20.In this case, can be installed on the wind-guiding panel 20 with installing and removing, wind-guiding panel 20 can be installed and removed with respect to shell 3 through barre 32.
In air conditioner, with respect to indoor unit, at the outdoor outdoor unit that does not have expression among the figure that also is provided with.Compressor, heat exchanger, cross valve and outdoor fan etc. are installed in outdoor unit, utilize these devices and indoor heat exchanger 1 to form kind of refrigeration cycle 40.As shown in Figure 7, the control device 41 of control kind of refrigeration cycle 40 is arranged in the indoor unit.The control device 41 that is made up of microprocessor is controlled kind of refrigeration cycle 40 and is made the cooling and warming unit running according to user's instruction and the detection signal that detects the various sensors 42 such as temperature sensor of room temperature or outside air temperature.At this moment, control device 41 comes switch wind-guiding panel 20 according to the running gauge tap mechanism of cooling and warming unit.In addition, control device 41 regularly or according to control 8 pairs of filters 7 of clearing apparatus from user's instruction cleans.
As shown in Figure 7, switching mechanism is by wind-guiding panel 20 is constituted with respect to the moving part 50 of shell 3 clutches and in the restrictions of opening direction 51 that wind-guiding panel 20 moves time limit system wind-guiding panel 20.
When opening wind-guiding panel 20, moving part 50 makes wind-guiding panel 20 move to the direction of leaving shell 3.At this moment, any one unfolding mode during restrictions 51 allows upwards to open or open is downwards opened to another direction through restriction, switches the direction of opening of wind-guiding panel 20.If restriction is opened downwards, then wind-guiding panel 20 is upwards opened.On the contrary, if restriction is upwards opened, then wind-guiding panel 20 is opened downwards.When closing wind-guiding panel 20, moving part 50 makes wind-guiding panel 20 move to the direction near shell 3.
That is to say, restrictions 51 through pinning axle 23 or lower shaft 22 so that its mode that does not move limits the direction of opening.When opening downwards, pin lower shaft 22 and make it keep rotating freely, and decontrol and go up axle 23.When upwards opening, axle 23 and it keep to be rotated freely in the pinning, and decontrol lower shaft 22.
In addition, restrictions 51 has and makes wind-guiding panel 20 remain the function of closed posture.The wind-guiding panel 20 of closed posture is near the front panel 21 of shell 3.At this moment, restrictions 51 is pinned and is gone up axle 23 and lower shaft 22.Even apply the external force that to draw back wind-guiding panel 20, because two axles 22,23 are lockable, so wind-guiding panel 20 is motionless.
As the drive source that is used for switch wind-guiding panel 20, only have the drive source that is used to wind-guiding panel 20 is moved and get final product.And the simple motion that drive source moves back and forth wind-guiding panel 20 gets final product.Therefore, the moving part 50 that wind-guiding panel 20 is moved back and forth can be simple mechanism.Thus, can simplify switching mechanism, realize the miniaturization of switching mechanism.

Limiting groove 72 is made コ shape substantially.Limiting groove 72 is made up of last locked groove 72a, medial launder 72b, following three grooves of locked groove 72c, and three grooves link together continuously.Last locked groove 72a is the circular arc formation at center along the axle 64a of an end of above link member 64.Following locked groove 72b is the circular arc formation at center along the axle 65a of an end of following link member 65.Medial launder 72b is the circular arc formation at center along the fixed axis 67 with interlock plate 66.
Shown in Fig. 9 (a), Figure 10 (a), when the axle 64b that two other ends are arranged in medial launder 72b, 65b, each is linked up with 52,53 and supports upward lower shaft 22,23 respectively, pins two axles 22,23.With this moment state as original state.Shown in Fig. 9 (b), Figure 10 (b), the axle of the other end of link member 64 during 64b in last locked groove 72a, having, on link up with 52 clampings and rotate to support freely and go up axle 23, and pin and go up axle 23.Lower draw-bar 53 breaks away from from lower shaft 22.Shown in Fig. 9 (c), Figure 10 (c), when the axle 65b of the other end that lower link spare 65 is arranged in following locked groove 72c, lower draw-bar 53 clampings are also rotated and are supported lower shaft 22 freely, and pin lower shaft 22.Last hook 52 breaks away from from last axle 23.
When being in original state,, go up then that locked groove 72a moves on the 64b edge of the other end of link member 64 if interlock plate 66 rotates around clockwise direction.The axle 64b of the other end of last link member 64 is that along the circumferential direction move at the center with the axle 64a of an end.Because last link member 64 does not move along radial direction, so the axle 64a of an end does not move yet.Therefore going up hook 53 does not rotate.On the other hand, the axle 65b of the other end of lower link spare 65 moves along medial launder 72b.The axle 65a that draws an end moves.Lower draw-bar 53 rotates around clockwise direction.Therefore, shown in Fig. 9 (b), Figure 10 (b), removed the locking-in state of lower shaft 22.When being in original state, then same shown in Fig. 9 (c), Figure 10 (c) if interlock plate 66 is around counterclockwise rotating, the locking-in state of axle 23 in the releasing.
Restrictions motor 70 about control device 41 drives so that above-mentioned action about restrictions 51 in synchronously.Restrictions motor 70 uses step-by-step motor, carries out rotating according to opening direction.Therefore, about wind-guiding panel 20 is not understood the distortion but open smoothly.
At the set inside pair of right and left moving part 50 of shell 3, this moving part 50 is configured in the outside that more relies on left and right directions than restrictions 51.Like Figure 11～shown in Figure 13, the front end of bar 32 stretches out from the hole 21b (with reference to Fig. 3) of vertical length that plate 21 in front forms laterally.Support member 31 is provided with the bolster 80 that is used for mounting rod 32.The front end of bar 32 rotates and is supported on freely on the bolster 80.Bolster 80 is located at a forward side of central authorities on the fore-and-aft direction prejudicially.The section of bar 32 is circular, because wind flows along the surface when top easily, so also be not easy the dew that condenses even blown to by cold wind.In addition, bar is a hollow structure.Therefore can not only keep intensity but also lightweight, thereby can alleviate the load that makes the motor that bar 32 moves.
When opening wind-guiding panel 20, portion of travel mechanism 57 forwards moves the front end of bar 32, when closing, rearward moves.Portion of travel mechanism 57 support bars 32 are as the movable plate that moves back and forth 81.Shown in figure 15, movable plate 81 is made fan-shaped, rotates to be supported on freely on the fixed axis 83 that is fixed on the base plate 82.Base plate 82 is fixed on the shell 3.
Moving part 50 is also the same as blocking with restrictions 51.Wherein, restrictions 51 is configured in the space of shell 3 left and right sides with moving part 50 side by side.If be combined into a unit to both, then can be used as the switching mechanism unit and use, make installation exercise become easy like this.In addition, owing to can constitute moving part 50, can make the unit realize miniaturization and slimming by part seldom.Therefore, the switching mechanism of can in limited space, packing into, thus can increase the width of blow-off outlet 5.If adopt big blow-off outlet 5, then the blowing range of width becomes big, can keep watch and deliver to each corner in room.
The rear end of bar 32 is installed near the front end of movable plate 81 through turning cylinder 84 rotations freely.On movable plate 81, form arc groove 85.Arc groove 85 forms on the circular arc that with fixed axis 83 is the center.On arc groove 85, form tooth bar.Drive division 58 is made up of switch motor 86 and the gear 87 that is installed on the motor reel.Be inserted into this gear 87 in the arc groove 85, itself and tooth bar are meshed.
If driving switch motor 86 is then followed the rotation of gear 87, movable plate 81 rotates around fixed axis 83, and bar 32 is from front panel 21 turnover.Shown in figure 11, when wind-guiding panel 20 was closed posture, movable plate 81 was positioned at rear side.Only the front end of bar 32 stretches out from front panel 21.This state is an original state.
When removing the locking-in state of lower shaft 22, if driving switch motor 86 is then shown in figure 12, movable plate 81 is around counterclockwise rotating.Bar 32 is forced out, and its front end forwards moves.Wind-guiding panel 20 rotates and upwards opens around last axle 23.Gauge tap motor 86 is so that movable plate 81 turns an angle, for example rotates 50 degree.
When removing the locking-in state of going up axle 23, if driving switch motor 86 is then shown in figure 13, movable plate 81 is around counterclockwise rotating.Bar 32 is forced out, and front end forwards moves.Wind-guiding panel 20 rotates and opens downwards around lower shaft 22.At this moment, owing to wind-guiding panel 20 is opened with the mode that descends, so the front end of bar 32 also slowly descends and moves forward.In this case, movable plate 81 also only turns an angle.
When wind-guiding panel 20 is opened, if driving switch motor 86 makes movable plate 81 rotate around clockwise direction, then wind-guiding panel 20 will be closed.Utilize the rotation of movable plate 81, the rear end of bar 32 is rearward moved.Bar 32 is drawn in the shell 3.Follow this process, the wind-guiding panel more than 20 axle 23 or lower shaft 22 be center rotation.Wind-guiding panel 20 becomes closed posture near shell 3.
In addition, the switch motor 86 about control device 41 drives, make above-mentioned action about moving part 50 in synchronously.Switch motor 86 uses step-by-step motor, carries out rotating according to switch.
In the cooling and warming unit operation process, when wind-guiding panel 20 is in when opening posture, wind-guiding panel 20 is lived by any shaft lock in the last lower shaft 22,23.For example wind-guiding panel 20 draws by force wind-guiding panel 20 if apply external force when being in the posture of upwards opening, and then an axle is urged (axle 23 on this is).If last axle is urged, then going up hook 52 will be to counterclockwise rotating.Last link member 64 is pushed to axis direction.Axis direction is that an end of link member 64 and the direction of the other end are gone up in connection.The other end of last link member 64 is pushed objective table 71 through limiting groove 72.At this moment, it is vertical substantially to be positioned at the axis direction of direction and last link member 64 of last locked groove 72a of the other end of link member 64.Because objective table 71 is fixed, last link member 64 does not move to axis direction.Action direction from the power of last link member 64 is vertical substantially with last locked groove 72a.On the other end of last link member 64, be not applied the power parallel with the direction of last locked groove 72a.Thus, last link member 64 does not move along last locked groove 72a, has stoped the rotation of last hook 52.
Thus, last axle 23 is firmly held through last hook 52.Therefore, even external force acts on the wind-guiding panel of opening 20, last axle 23 can not thrown off from last hook 52 yet.
Be positioned at wind-guiding panel 20 under the situation of opening posture downwards too, even external force acts on the wind-guiding panel of opening 20, lower shaft 22 also can not thrown off from lower draw-bar 53.
That is to say, when wind-guiding panel 20 is opened,, can prevent that locking-in state is disengaged even the external force of applying becomes vertical relation through the direction that makes link member 64,65 and limiting groove 72.Therefore, can avoid the axle of wind-guiding panel 20 to throw off from shell 3, the wind-guiding panel 20 that causes opening is supported by bar 32 and the situation of suspending in midair.
In addition, when wind-guiding panel 20 was in closed posture, last axle 23 was pinned by hook 52,53 respectively with lower shaft 22 and keeps.Therefore, wind-guiding panel 20 is thrown off from shell 3.And, because the wind-guiding panel 20 of closed posture becomes the part of shell 3 front panels, so can all of a sudden not throw off because of the object that tangles the outside from axle.
And, in this switching mechanism, adopt the structure that mechanically connects hook 52,53 up and down, drive by a restrictions motor 70.Therefore, each links up with actuation time of 52,53 can deviation, thereby pins or open axle 22,23 reliably.So, the situation of each locking-in state of 22,23 can not take place to remove simultaneously, thereby can improve the reliability of switch motion.
When wind-guiding panel 20 was opened to greatest extent, with the orientation independent of opening, the amount of movement of bar 32 was certain.But, because the front position of the bar 32 relative with wind-guiding panel 20 is eccentric, so like Fig. 4, shown in Figure 6, open angle is different upwards opening when opening downwards.Open angle when the open angle ratio when upwards opening is opened downwards is big.That is to say that the center when opening is near more to the distance of fulcrum, the angle of opening is just big more.The center is to go up axle 23 or lower shaft 22, and fulcrum is the position of bar 32 front ends.Because bar 32 is mounted close to axle 23, so the open angle of upwards opening is big, the open angle of opening downwards is little.
When thermantidote turns round, open downwards, if open angle is big, then wind-guiding panel 20 drops to lower than horizontal line.This flows cold wind in the horizontal direction, does not produce the air-flow towards the roof.The cold wind reach shortens, and cold wind directly blows to the people.Hope when therefore, opening that the angle of opening is little downwards.When heating installation turns round, upwards open, if open angle is little, the outlet of warm braw narrows down.Blowing to the warm braw that wind-guiding panel 20 returns does not have other flow directions, makes movement disorder with the warm braw collision that blows out.Its result wind speed of blowing out of direction earthward dies down, and makes warm braw can not arrive ground.
So just can not when cooling and warming unit turns round, blow effectively, can not bring into play its ability to greatest extent.But, as stated, become big through making the open angle of upwards opening; The open angle of opening downwards diminishes; When thermantidote turns round, can make cold wind blow to the roof, the outlet of warm braw is widened, thereby form warm braw air-flow smoothly.Therefore, can bring into play the maximum capacity of air conditioner to greatest extent.
The instruction of air conditioner during through user's remote controller, maybe when having arrived the setting-up time of timer, make the cooling and warming unit running.Control device 41 control kind of refrigeration cycle 40, and the switch of control wind-guiding panel 20.At this moment, control device 41 makes moving part 50 and restrictions 51 interlocks.
When cooling and warming unit turned round, control device 41 made the driving to restrictions motor 70 and switch motor 86 begin or stop according to preset time.That is to say each motor 70,86 of sequential control.
In addition, control device 41 judged whether to carry out initialization action before entry into service.That is to say that control device 41 is judged the position of the wind-guiding panel 20 when running stops, when not being in original state, make moving part 50 and restrictions 51 actions as initialization action, so that it becomes original state.When entry into service, being in original state, do not carry out initialization action, directly entry into service.In addition, wind-guiding panel 20 is an original state when being in closed posture, and the state of each member of the open angle of wind-guiding panel 20 and moving part 50 and restrictions 51 has relevance.
Below the necessity that makes wind-guiding panel 20 become the initialization action of original state before the entry into service is described.Suppose under the state of upwards opening, to shut down like Fig. 4 because of certain reason causes indoor unit.Receive in this state when opening the instruction of entry into service downwards; If do not carry out initialization action; And the action of directly opening downwards then under the state that lower shaft 22 is not pinned by lower draw-bar 53, is just directly thrown off the upward axle 23 that is pinned by last hook 52; Thereby make wind-guiding panel 20 break away from shell 3, the situation of being suspended in midair occurs by bar 32 supports.For fear of this situation, need carry out initialization action.When transferring to when carrying out opening action,, also need carry out initialization action simultaneously in order to open wind-guiding panel 20 with desirable open angle.
Shown in figure 11, the position-detection sensor 90 that is used to detect wind-guiding panel 20 open positions is arranged on moving part 50.And, on the moving part 50 about position-detection sensor 90 is arranged on.Position-detection sensor 90 is a limit switch.Position-detection sensor 90 is installed in the shell 3, on the base plate 82 of moving part 50.Position-detection sensor 90 is configured near the movable plate that is in original state 81.When being in original state, the bar 32 that is installed on the movable plate 81 contacts with position-detection sensor 90.Therefore, position-detection sensor 90 detects wind-guiding panel 20 and is in original state, promptly is in closed posture.
Control device 41 judges according to the detection signal of position-detection sensor 90 whether wind-guiding panel 20 is in original state.Usually, wind-guiding panel 20 was in closed posture when running stopped, and moving part 50 also is in original state with restrictions 51.At this moment, be in original state, then do not carry out initialization action if control device 41 detects.
But when causing not being in original state owing to certain situation, control device 41 is not in original state according to judging from the detection signal of position-detection sensor 90.Control device 41 carries out initialization action, forcibly makes it become original state.
In the past; Store wind-guiding panel 20 in advance as initialization time from maximum open mode (full open position) to the time of closed condition (original state); When thermantidote or heating installation entry into service; Must in initialization time, close the initialization action of wind-guiding panel 20, after making wind-guiding panel 20 become closing state reliably, thermantidote or heating installation etc. run well.But; In this initialization action in the past; Even owing to when entrys into service such as thermantidote or heating installation, be in original state, also must in initialization time, carry out initialization action, need the time so transfer to the regular event of thermantidote or heating installation.
As this embodiment,, can detect whether wind-guiding panel 20 is in original state when the running beginning through position-detection sensor 90 is set.Thus, begin, when wind-guiding panel 20 is in original state, can carry out initialization action, and directly carry out the running of thermantidote or heating installation when turning round.
When running beginning, when wind-guiding panel 20 is not in original state, carry out initialization action, when position-detection sensor 90 detects when being in original state, can stop initialization action, transfer to the running of thermantidote or heating installation.In addition; Even wind-guiding panel 20 is not in maximum open mode; And be in slightly open mode or be opened to the state about the centre, also carry out initialization action, owing to detect termination initialization action when being in original state when position-detection sensor 90; Even, also can transfer to the running of thermantidote or heating installation so be not till arriving initialization time, all to carry out initialization action always.For example,, after 15 seconds, be in original state, then stop initialization action, transfer to normal operation if position-detection sensor 90 detects from the beginning initialization action even be decided to be 30 seconds to initialization time.In this case, can make the time ratio that carries out initialization action shorten 15 seconds in the past.
As stated, through being used to the testing result of detecting sensor 90, can reduce the needed time of initialization action, thereby can transfer to normal operation apace from the position.
Up to detecting through position-detection sensor 90 till wind-guiding panel 20 is in original state, the action of opening wind-guiding panel 20 that is not used to run well, and only carry out initialization action.
Even carried out initialization action with the stipulated time, also not detecting wind-guiding panel 20 at position-detection sensor 90 becomes under the situation of original state, might be to receive auxiliary shutter board (not diagram) to disturb and cause wind-guiding panel 20 not close.In this case, at first in order to make it become full open position from original state, the opening action between only carrying out in case of necessity temporarily makes wind-guiding panel 20 become full open position.At this moment, make axle 22 or 23 of current support keep standing states, do not switch the axle 22 or 23 of support.If because switched the axle of support, the axle 23 of going up that then wind-guiding panel 20 pins is all thrown off with lower shaft 22 both sides, might make wind-guiding panel 20 become the situation of being suspended in midair by bar 32 supports.After making wind-guiding panel 20 become full open position, make auxiliary shutter board become closed condition.After this, make wind-guiding panel 20 in initialization time, carry out closing motion, return original state.Even carrying out this action, position-detection sensor 90 can't detect wind-guiding panel 20 to be become under the situation of original state, and control device 41 shows it as the undesired mistake of carrying out of action.In above-mentioned explanation, though make wind-guiding panel 20 become full open position, may not make it become full-gear, assist shutter board to become the state that can rotate as long as be opened to wind-guiding panel 20 to make at least.
In addition, when being connected to the plug of air conditioner on the domestic power supply at first, perhaps under because of situation such as power supply to air conditioner such as have a power failure are cut off midway, need making among the figure not, the auxiliary shutter board of expression becomes closed condition.At first be opened to wind-guiding panel 20 to make at least and assist shutter board to become the state (can certainly be opened to full open position) that can rotate, after making auxiliary shutter board become closed condition, make wind-guiding panel 20 become original state again.
Under original state, shown in figure 11, in moving part 50, movable plate 81 is positioned at the position of rear side.Shown in Fig. 8, Figure 10 (a), in restrictions 51, the axle 64b of the other end of upper and lower strut spare 64,65,65b are arranged in medial launder 72b.At this moment, wind-guiding panel 20 is a closed posture, and last axle 23 is lockable with lower shaft 22 simultaneously.After this, corresponding to the thermantidote running, control device 41 is removed and is gone up any one locking-in state in axle 23 or the lower shaft 22, and wind-guiding panel 20 is opened.
If the running of beginning heating installation, then control device 41 at first drives the restrictions motor 70 of restrictions 51.Through this driving interlock plate 66 is rotated around clockwise direction.Last link member 64 is that rotate at the center with an end.The axle 65b of the other end through lower link spare 65 moves along medial launder 72b, and link member 65 comes upwards to leave behind.Lower draw-bar 53 is removed the locking-in state of lower shaft 22 around clockwise rotating.
Control device 41 is to drive the switch motor 86 of moving part 50 start-up time that is slightly later to restrictions motor 70.Be the start-up time of switch motor 86 after lower draw-bar 53 is thrown off from lower shaft 22.That is to say that when having arrived the very first time of regulation, control device 41 stops restrictions motor 70.Shown in Figure 10 (b), this very first time is the time of confirming according to the time of the terminal point of locked groove 72a in the axle 64b arrival of the other end of last link member 64.After restrictions motor 70 stops, control device 41 driving switch motor 86.
Through driving switch motor 86, movable plate 81 is around counterclockwise rotating.Bar 32 is pressed towards the place ahead, and wind-guiding panel 20 moves to the direction of leaving shell 3.Wind-guiding panel 20 is opened around last axle 23.If arrive the open angle of setting, then control device 41 stops switch motor 86.In addition, can calculate open angle from the pedometer of switch motor 86.
Control device 41 if arrived for second time, then makes switch motor 86 stop with certain hour driving switch motor 86.At this moment, reach maximum open angle shown in Figure 12.Wind-guiding panel 20 becomes upwards opens posture, makes warm braw blow to ground.
Under the situation of thermantidote running, control device 41 is also at same time control restrictions motor 70 and switch motor 86.But restrictions motor 70 opposite direction when turning round with heating installation is rotated.Switch motor 86 rotates to identical direction.
If second time then the switch motor 86 that arrive after driving with certain hour stop.At this moment, arrive maximum open angle shown in Figure 13.Wind-guiding panel 20 becomes opens posture downwards, makes cold wind blow to the roof.
When making the thermantidote entry into service, carry out fast-refrigerating.At this moment, wind-guiding panel 20 is at first upwards opened, and becomes and upwards opens posture.After this, wind-guiding panel 20 is closed, and becomes closed posture.Last lower shaft 22,23 temporarily is lockable.Wind-guiding panel 20 is opened downwards then, becomes to open posture downwards.Thus, the wind-guiding panel of opening in change 20 open direction the time, at least one 22 or 23 remains the state that is lockable.Therefore, can not produce the state that two axles 22,23 are decontroled simultaneously.Thus, can prevent that wind-guiding panel 20 is thrown off in wind-guiding panel 20 switching processes.
If thermantidote running finishes, control device 41 driving switch motor 86 at first then.Bar 32 is pulled, and wind-guiding panel 20 is near shell 3.If arrive the 3rd time of regulation, then control device 41 stops switch motor 86.This moment is shown in figure 11, and wind-guiding panel 20 becomes closed posture, and movable plate 81 is positioned at the position of rear side.That is to say that the 3rd time was the time of confirming the time when turning back to original state according to movable plate 81.In addition, position-detection sensor 90 detects the situation that movable plate 81 turns back to original state.The 3rd time also can be corresponding to the time of this detection.
After this, control device 41 drives restrictions motor 70.For example, under the situation of heating installation running, from the state variation shown in Figure 10 (b) to the state shown in Figure 10 (a).Lower draw-bar rotates lower shaft 22 is lockable.If reach the 4th time of regulation, then control device 41 stops restrictions motor 70.The 4th time was to be connected the time that time of the position of medial launder 72b and following locked groove 72c confirms according to the axle 65b of lower link spare 65 other ends from the position arrival that connects locked groove 72a and medial launder 72b.
In addition, the present invention is not limited to above-mentioned embodiment, can more revise and change above-mentioned embodiment within the scope of the invention certainly.Hook and lower draw-bar are being set on the wind-guiding panel, axle and lower shaft are being set on the shell.Lower shaft is moved freely, lower draw-bar is become have the bearing of the patchhole of axle.Through embedding inserting in the hole of hook to axle, make the wind-guiding panel keep rotating freely.When the wind-guiding panel was closed posture, last lower shaft embedded in the lower draw-bar respectively.When the wind-guiding panel was upwards opened, last axle kept original state, and lower shaft moves, and throws off from lower draw-bar.When opening, be opposite state downwards.
In addition, also can use the chuck of clamping axle or lower shaft to substitute hook.Clamp each through chuck, pin and support each.Through making chuck leave each, locking-in state is disengaged.Part through clamping chuck on axle is done circularly, can rotate and support each freely.
Position-detection sensor also can be arranged on the bar.In addition, position-detection sensor also can directly detect the position of wind-guiding panel, is not limited to touch sensors such as limit switch, also can use noncontacting proximity sensors such as optical sensor, video camera.
Also can about moving part on the pair of right and left position-detection sensor is set.Thus, even detect the original state of wind-guiding panel in a side, and opposite side does not detect under the situation of original state, can only make the moving part action of opposite side yet, thereby makes the wind-guiding panel revert to normal state from the state of distortion.
