Description

Air conditioner
Technical field
The present invention relates to air conditioner, relate in particular to up-down wind direction board has been carried out improved air-conditioning.
Background technology
Heat pump type air conditioner is extensively popularized as air-conditioner, has carried out various trials in order to become more comfortable easier use.One of them can enumerate the shape of up-down wind direction board.
In heat pump type air conditioner, divergence type wall-hanging is owing to extensively popularized with aspect such as the coordination in house, appearance design, low noise.In this occasion, because indoor set is installed in the top of chamber interior walls, therefore when carrying out the heating installation running, make up-down wind direction board that warm braw is arrived near the floor as far as possible, when carrying out cold air operation, make the above-below direction plate make cold wind near horizontal direction widely in indoor circulation.
Though heat pump type air conditioner all carries out miniaturization every year, also has the problem on the performance, the speed of miniaturization is not too big.Therefore, though when using because the comfort that air conditioner brings, its size does not become problem, and is many when stopping owing to access times are few during the stage casing in spring, autumn, so has a lot of people to feel inharmonious with internal environment because of it is big or small yet.Owing to this reason, wish to appear at the air conditioner that becomes the situation that does not upset indoor environment when not using.In order to satisfy this demand, also implemented the air conditioner main body is installed among the wall and be only limited to the suction inlet of air, the method for blow-off outlet from the indoor part that can see.But, for bigger air conditioner is installed in the wall, must in wall, guarantee bigger space in advance, and the house that satisfies it is limited to minority.
Therefore, though to require to expose when not using from wall be the wall air conditioner of not upsetting the outward appearance of indoor environment.When having stopped running, cover blow-off outlet with up-down wind direction board, prevent that dust from entering in the indoor set, and, make concavo-convex unshowyly as far as possible making, time has been descended in the appearance design aspect of the appearance design that combines together with wall, the slyness that does not have corner part.
In addition, when carrying out cold air operation, because up-down wind direction board is exposed in the cold wind of producing by boasting, and its part also is exposed in the room air that the cold wind that is blown out induces, therefore be easy to generate dewfall, if do not make suitable structure, then dewfall falls in turning round for a long time, sometimes make dirty air conditioner around, this class phenomenon is also needed to take measures.
As this prior art, at patent documentation 1: TOHKEMY 2000-111133 communique, patent documentation 2: No. 3081471 communiques of Japan's special permission, patent documentation 3: TOHKEMY 2004-116859 communique, patent documentation 4: open in No. 2745741 communiques of Japan's special permission.
Patent documentation 1 has been narrated following air conditioner, on the rear side that becomes the wind upside of change left and right sides wind direction board group, setting constitute by a plurality of protuberances and prevent air-flow peel off first peel off anti-locking mechanism, on the rear side that becomes the wind upside of change up-down wind direction board, be provided with second and peel off anti-locking mechanism, prevent the generation of peeling off and prevent dewfall of air-flow, can change wind direction effectively.
Patent documentation 2 has been narrated following air conditioner, upper wall position nearby in the air channel that arrives wind direction alteration board from air blast is provided with auxiliary wind direction alteration board, to near the upper wall in air channel, flow air make its blow-off direction consistent with this auxiliary wind direction alteration board with the air that blows out from blow-off outlet to the direction guiding identical with wind direction alteration board.
Patent documentation 3 has been narrated following air conditioner, on blow-off outlet, be set up in parallel 3 horizontal shutter boards, when sending the adjusting air upward, the horizontal shutter board of central authorities and below is configured in and normal place at the air almost parallel of the central portion in air-supply path and bottom circulation, thereby the main flow direction below of wind is sent.The horizontal shutter board of top is with respect to configuration obliquely above the air flow of the air of the top circulation in air-supply path, and the air on the top by the air-supply path is guided by horizontal shutter board and sends along the upper wall in air-supply path.The air of sending is upward attracted by main flow by wall attachment effect, is directed to the direction of main flow, prevents dewfall and prevents the minimizing of air quantity.
Patent documentation 4 has been narrated the wind-direction deflection device of following air conditioner, the cross section of shutter board is made to the big fan shape of the protruding amount of deflection of upside, and the end difference that the thickness that the downstream is set is thicker than upstream side, and make the uniform hollow section of thickness of face on the shutter board face.Thus, not a halfpenny the worse, owing to when cold air operation, utilize end difference that air-flow is peeled off and easily towards level, when heating installation turns round, can not cause the increase of resistance and make warm braw downward, so can avoid the decline of air quantity, the increase of noise, its result, the arrival degree that warm braw arrives ground increases, and can make the indoor Temperature Distribution of carrying out air-conditioning become even.
For the up-down wind direction board of heat pump type air conditioner, various schemes have been proposed as mentioned above.But,, when visually seeing wind direction board, stay the impression that blows out to the tangential direction of flexure plane from the wind direction board front end as wind in occasion with crooked wind direction board change wind direction.Therefore, the occasion of the wind direction board that uses crooked for the profile when stopping is consistent, also there is the restriction on the size, the inconsistent sensation of being expected when especially bringing the impression of the wind direction that the front end of the up-down wind direction board of upside gives and heating installation running or during cold air operation of wind direction.
Though in patent documentation 1, narrated the situation that air-flow is blown out downwards, do not mentioned the situation that air-flow is blown out upward.
Though in patent documentation 2, narrated the situation that air-flow is blown out downwards, do not mentioned the situation that air-flow is blown out upward.And, because wind direction board is 3 the air channel narrowed down, so especially in the occasion of the wind direction board of the thick blade shape of used thickness, up-down wind direction board and blowing out between the upper wall of air channel narrows down when cold air operation, wind speed increases and the flowing resistance of this part is increased, and noise increases.
Though in patent documentation 3, narrated upwards or horizontal direction blows out the situation of air-flow, made the situation about being directed downwards of air-flow not mentioning when turning round as heating installation.And, certain direction of also not mentioning the wind direction board warpage of the occasion that blows out air-flow downwards.
In patent documentation 4, because end difference is arranged on wind direction board, so even close blow-off outlet when stopping, end difference is also very showy, the outward appearance when infringement stops.And, because two the heaving of wind direction board, so with regard to the posture of the wind direction board during with regard to cold air operation, the impression of the wind direction that wind direction board is given is unbecoming with expectation towards equidirectional.
Summary of the invention
The objective of the invention is to, when the running of air conditioner, the impression of the wind direction when making the wind direction expected and seeing up-down wind direction board is consistent.

Then, use Fig. 2~Fig. 8 that the upside up-down wind direction board of embodiment is described.
As mentioned above, up-down wind direction board is made of upside up-down wind direction board 291 and downside up-down wind direction board 292.Two up-down wind direction boards representing upside up-down wind direction board 291, downside up-down wind direction board 292 in this manual in the occasion of only having put down in writing up-down wind direction board then are recited as upside (or downside) up-down wind direction board when a up-down wind direction board of upside (or downside) up-down wind direction board is narrated.
Up-down wind direction board 291,292 is supported on the pillar 291s rotationally with axle on the whole transverse width on the top of air blow-off outlet 29, carries out deflection by the up-down wind direction board CD-ROM drive motor, thereby blow out air is blown out downwards, and perhaps level blows out etc.
At first, use the state of Fig. 3, Fig. 5, the up-down wind direction board of Fig. 8 (a) when running is stopped to be elaborated.Fig. 3 (a) is the stereogram of the running of identical indoor set when stopping, and Fig. 3 (b) is the cutaway view of the blow-off outlet of identical indoor set running when stopping.Fig. 5 stereogram of up-down wind direction board that has been opening of identical indoor set.The cutaway view of the up-down wind direction board when Fig. 8 (a) is stopping of identical indoor set, the cutaway view of the up-down wind direction board when Fig. 8 (b) is identical indoor set cold air operation, Fig. 8 (c) is the cutaway view of the up-down wind direction board of identical indoor set wind direction when making progress, the cutaway view of the up-down wind direction board when Fig. 8 (d) is the running of identical indoor set heating installation
In Fig. 3, Fig. 8, label 290a blows out the air channel upper wall, and 290b blows out the air channel lower wall, and 290e blows out expansion section, air channel top, 291a be level at present crosswind to face, upside wind direction face when 291b is level, 291s is a pillar.
Upside up-down wind direction board 291 has hollow wing cross section, as shown in Figure 5, blow out air channel 290 about the bearing that is provided with of three places of sidewall 290c, 290d, upper wall 290a on, the rotatable axial region that is supported with pillar 291s freely is located on the whole transverse width of air blow-off outlet 29.
When not using the running of air conditioner to stop as shown in Figure 3, upside up-down wind direction board 291.Downside up-down wind direction board 292, drop front 251 are controlled so as to by control device and close air blow-off outlet 29.Thus, upside up-down wind direction board 291 rotates and is contained in wherein to the position in the place ahead of expansion section, the top 290e that blows out air channel 290, covers top, air channel expansion section 290e, closes blow-off outlet 29 with 292 co-operatings of downside up-down wind direction board.
At this moment, because upside up-down wind direction board 291 is positioned at the cross-shaped portion of front and the bottom surface of air conditioner, the outside wind direction face 291a outside therefore becoming makes the big curved surface of as Fig. 8 (a) slyness and curvature and consistent with the profile of air conditioner.By like this, upside up-down wind direction board 291, downside up-down wind direction board 292 can form the profile of face on earth from the front of air conditioner continuously sleekly with the wind direction face that becomes the outside.
Therefore, when not using air conditioner, become the outward appearance that does not have unnecessary concavo-convex and soft coordination, can not upset indoor atmosphere.
Like this, the air conditioner of embodiment is when having cut out above-mentioned a plurality of up-down wind direction board, and the wind direction face of the profile from the bottom surface of air conditioner to front panel below the becoming when the cold air operation of up-down wind direction board forms sleekly.
In addition, the air conditioner of embodiment has the control device of cutting out above-mentioned up-down wind direction board when having stopped the running of air conditioner.
Thus, when having stopped air conditioner, up-down wind direction board just is contained in the expansion section that blows out the air channel, and its outer shape of making continuous slyness from the front panel to the bottom becomes the appearance design that does not have unnecessary concavo-convex smoothness.
Therefore, when stopping, running also can provide the air conditioner that can not upset the atmosphere of interior decoration.
The state of the up-down wind direction board when then, using Fig. 4, Fig. 8 (b) to cold air operation describes.The cutaway view of the blow-off outlet the when stereogram when Fig. 4 (a) is the cold air operation of identical indoor set, Fig. 8 (b) are the cold air operations of identical indoor set.
In Fig. 4, Fig. 8,290c, 290d blow out the left and right sides, air channel wall, downstream when 291c is level, upstream extremity when 291d is level.
When air conditioner was carried out cold air operation, as shown in Figure 4, upside up-down wind direction board 291, downside up-down wind direction board 292 were made and are blown out the upper wall 290a in air channel 290, the posture of lower wall 290b almost parallel or the direction of level and use.The cold wind that is blown out is if directly blow to indoor occupant and then produce sticky feeling, so, in order not allow the cold wind that blows out directly blow to indoor occupant, suitably changes the direction of up-down wind direction board with remote controller, remains comfortable humiture with indoor.
At this moment, if observe air conditioner, because air conditioner is installed in the eminence of indoor wall, so what can see is the following wind direction face of becoming of upside up-down wind direction board 291 (becoming the wind direction face of outside when closing), owing to this wind direction face along with from the inboard that blows out air channel 29 towards in face of the side lateral bending song that makes progress, thereby the wind direction of blow out air also feels it is towards upside from level side, this is expected for not hope with the direction of cold wind, and directly to blow to inhabitation personnel's wind direction consistent, and, also roughly consistent with actual wind direction, do not have inharmonic sensation and can accept.In a word, during cold air operation, the impression of the wind direction in the time of can making the wind direction expected and see up-down wind direction board is consistent.
In addition, because the top 291b of upside up-down wind direction board 291 also makes convex as Fig. 8 described later (b), so if see that this wind direction face 291b then probably brings the downward misunderstanding of wind direction, but since as mentioned above air conditioner be installed in the eminence of indoor wall, so see upside up-down wind direction board 291 top 291b chance seldom.And as described later, the convex of top wind direction face 291b so the impression of bringing is also very thin, does not almost feel that wind direction is downward because the wind direction face 291a below its ratio of curvature is little.
Therefore, can not bring the downward misunderstanding of wind direction.
In addition because up-down wind direction board roughly keeps the posture of level, so when stopping with the running of the posture that keeps tilting with bigger angle relatively, because of the distortion that is caused by deadweight of up-down wind direction board becomes big.For air conditioner because near blow-off outlet noticeable easily, so excessive for the distortion that does not make up-down wind direction board, need to consider the material and the shape of up-down wind direction board.
In an embodiment, in order to reduce this distortion, make wing inside hollow.In an embodiment, the material of up-down wind direction board is used styrene resin, and wing thickness is 7mm, and the length from wing upstream extremity 291d to downstream 291c is 37mm, and the distance between the pillar 291s is 305mm, utilizes the auxiliary law of calming the anger to carry out injection molded.
In addition, in an embodiment, shown in Fig. 8 (b), from the position of wing maximum ga(u)ge D to short than from the position of maximum ga(u)ge D to upstream extremity 291d of the distance A of downstream 291c apart from B.So, wing downstream (becoming the front end of upside when the closing) 291c that makes upside up-down wind direction board 291 is thicker, and 291d is thinner for upstream extremity (becoming the front end of downside when closing).
Thus, the rigidity of the downstream 291c of the upside up-down wind direction board of seeing easily when watching air conditioner attentively 291 part increases, and has suppressed distortion.Therefore, the outward appearance of air blow-off outlet 29 parts improves.On the contrary, the rigidity of the upstream extremity 291d portion of upside up-down wind direction board 291 reduces, and distortion increases, but the inboard that becomes air blow-off outlet 29 owing to this part is difficult to see that the increase of distortion is less to the influence of outward appearance.
Have again, make hollow result, thermal resistance between following wind direction face 291a and the top wind direction face 291b increases, running through the cold and hot amount of flowing through reduces, the part that invalidly is cooled and reaches dewfall reduces, around the air conditioner that causes because of dispersing of water droplet and the pollution around the blow-off outlet 29 tail off, the outward appearance during the use air conditioner becomes good.
In addition, in an embodiment upside up-down wind direction board 291 is utilized pillar 291s suspension in upstream extremity 291d one side.Thus, expansion of the part of wing thin thickness and low upstream extremity 291d one side of intensity are hung by pillar 291s and suppress to be out of shape.Therefore, the difference of the deflection that is caused by intensity difference of the downstream 291c of the upside up-down wind direction board 291 when being arranged to approximate horizontal and upstream extremity 291d reduces, and can make the structure that keeps balance.
And, by upside wind direction face 291b is made the little mild convex of curvature, can reduce the value of maximum ga(u)ge D of the wing of upside up-down wind direction board 291, not rise so, can reduce the flowing resistance that causes by upside up-down wind direction board 291 at the wind speed of blow-off outlet 29.
Then, use the state of Fig. 6, Fig. 8 (c) up-down wind direction board when wind direction is made progress to describe.Fig. 6 is the cutaway view of the blow-off outlet of the wind direction of identical indoor set when making progress.
In an embodiment, the downstream that blows out air channel 290 be provided with enlarge upward above expansion section 290e.When carrying out the running of extremely weak cold air or heating installation, shown in Fig. 6, Fig. 8 (c), upside up-down wind direction board 291 is made progress a little, make downside up-down wind direction board 292 be in the posture of roughly closing.Thus, the part of blow out air becomes extremely weak wind and passes through expansion section, top 290e lightly in indoor diffusion, carries out the running of faint cold air or heating installation.
And, by utilizing top expansion section 290e, the short circuit running that the wind that carries out blowing out sucks from suction inlet 27 immediately, thus also can carry out the service action of the air conditioners such as deodorizing running of the dry operating of heat exchanger and air conditioner inside.
Like this, the air conditioner of embodiment, possesses the expansion section that blows out the air channel that enlarges upward in the downstream, with the front portion that when closing, is positioned at this expansion section and central portion have at surface and the back side convex the wind direction face and also inner be hollow upside up-down wind direction board, the average curvature of the wind direction face outside becoming when having closed this upside up-down wind direction board is bigger than the average curvature of other wind direction faces of up-down wind direction board, below this wind direction face that becomes the outside becomes, and this upside up-down wind direction board is being arranged to become the back when downward when this upside up-down wind direction board is arranged to horizontal direction.
In general, in air conditioner, in order to make warm air, make the up-down wind direction board of blow-off outlet downward during the heating installation running, make roughly one-tenth level of up-down wind direction board during cold air operation, the air that turns cold is flowed to guarantee comfortableness near face and head towards the underfooting.
This be because, because of the warm air of free convection up, cold air down, so by as above being provided with, then cold air/heating installation effect spreads all over whole indoorly, becomes comfortable indoor.
In addition, when utilizing up-down wind direction board to make wind deflection, when seeing up-down wind direction board, stay the impression of the direction shown in the downstream that wind direction deflected into up-down wind direction board instinctively.
And, because up-down wind direction board is located on the whole width of blow-off outlet,, produce bending because of deadweight easily so length is long.
Air conditioner according to embodiment, when having stopped air conditioner, the upside up-down wind direction board can be contained in the expansion section that blows out the air channel its outer panel shape slick and sly continuously in the past that form to the bottom, make the appearance design that does not have unnecessary concavo-convex smoothness, can not upset the atmosphere of interior decoration.
If from this air conditioner of indoor observation, when heating installation turns round, then see the up-down wind direction board that erects with subvertical angle roughly from oblique below, the convex surface in the outside of up-down wind direction board can be seen, intuitively produce and blow out that air-flow is induced by convex surface and towards the impression of below, this is consistent with actual wind direction and do not have inharmonic sensation, can not produce puzzlement.In a word, when heating installation turned round, the impression of the wind direction in the time of can making the wind direction expected and see up-down wind direction board was consistent, the puzzlement in the time of especially can eliminating the running of beginning heating installation.
In addition, when cold air operation, owing to be to see the up-down wind direction board of roughly being arranged to level from oblique below, so can see the convex surface of the downside of up-down wind direction board, intuitively produce the impression blow out that air-flow is induced by convex surface and to make progress a little from level, this is also consistent with actual wind direction and do not have inharmonic sensation, can not produce puzzlement.At this moment, though the upside of up-down wind direction board also becomes convex surface, because the convex surface of ratio of curvature downside is little, therefore protruding degree is little but as mentioned above,, and, because up-down wind direction board is in level or downward a little posture, so almost can't see the convex surface of upside, only notices the convex surface of downside, as mentioned above, stay the impression that air-flow makes progress a little from level.
And the position when having closed this upside up-down wind direction board becomes from the subvertical face of front panel and carries out the transition to position the way of face of approximate horizontal of bottom surface of air conditioner, and it is big that its profile need be made the continuous part of ratio of curvature and top or rear.Therefore, as mentioned above, preferably constitute, when having closed up-down wind direction board, make the face that becomes the outside when up-down wind direction board is arranged to level, become the wind direction face of downside.
Thus, the protruding degree of the wind direction face below becoming when up-down wind direction board is arranged to level increases, and as mentioned above, blows out air-flow from the impression that level makes progress a little when producing said cold air operation, is proper.
At this moment, though reduced when up-down wind direction board is arranged to level, to become the protruding degree of the wind direction face of upside, but as mentioned above, when up-down wind direction board is arranged to level, except being difficult to see the top curved surface, by doing like this, since both attenuate the thickness of up-down wind direction board, can not make the wind speed of blow-off outlet that too big raising is arranged again, so can suppress flowing resistance, the raising of realizability energy and the reduction of noise.
In addition, blow out the expansion section, top in air channel, can control wind direction,, then can add the function of the deodorizing of air conditioner inside and drying etc. by deliberately causing short circuit more towards the top by setting.
And, by up-down wind direction board being made hollow the wind direction face at the surface and the back side is made convex, and realize lightweight.Thus, can alleviate the deflection of the up-down wind direction board when using air conditioner, improve its outward appearance.And, hollow by making, also have the transmission that reduces the heat in up-down wind direction board, and the effect of the dewfall when suppressing cold air operation.
Like this, can be provided in and almost do not have the concavo-convex of outside when not using, can not upset the atmosphere of interior decoration, and the impression of the wind direction of the intuition of the direction that blows out air-flow in use when seeing up-down wind direction board is consistent and do not have inharmonic sensation, can produce puzzled air conditioner.
In addition, the air conditioner of embodiment, when making above-mentioned up-down wind direction board be in the posture of approximate horizontal, the distance from downstream to maximum ga(u)ge is shorter than the distance from upstream extremity to maximum ga(u)ge.
In general, what watch attentively naturally is blow-off outlet with the air conditioner of eyes in running the time, and the up-down wind direction board that is located at the ragged edge of this blow-off outlet exists the most boldly.This up-down wind direction board as mentioned above owing to be located on the whole width of blow-off outlet, so length is long, easily because of deadweight produces deflection, if the excessive then appearance damage of deflection, as the value decline of commodity.
According to the air conditioner of embodiment, when making above-mentioned up-down wind direction board be in the posture of approximate horizontal, the distance from downstream to maximum ga(u)ge is shorter than the distance from upstream extremity to maximum ga(u)ge.
Thus, when up-down wind direction board being arranged on the more cold air operation of this situation of the horizontal direction that is easy to generate deflection, the downstream of up-down wind direction board becomes the front side and sees easily, but downstream thickness is thicker, the intensity grow, deflection diminishes, and the distortion that eyes can be seen is suppressed.On the other hand, the upstream extremity thinner thickness of up-down wind direction board, weak strength, the deflection quantitative change is big.But upstream extremity is owing to the inboard that is positioned at air conditioner, so its distortion is unshowy, can not cause the deterioration of outward appearance.
Therefore, can provide the air conditioner that also can keep the outward appearance of blow-off outlet in the running well.
In addition, the air conditioner of the embodiment pillar that will support above-mentioned up-down wind direction board be located at upstream extremity one side above.
Thus, near the part expansion of the thin thickness of upstream extremity, bending strength is little, and the distortion that deflection becomes big upstream extremity easily also diminishes.
Therefore, can provide outward appearance to keep better air conditioner.
The state of the up-down wind direction board when at last, using Fig. 7, Fig. 8 (d) that heating installation is turned round describes.Fig. 7 (a) is the stereogram in heating installation when running of identical indoor set, the cutaway view of the blow-off outlet when Fig. 7 (b) is the heating installation running.
When air conditioner being carried out the heating installation running, up-down wind direction board 291,292 is as shown in Figure 7 with roughly subvertical posture use.By like this, flow through the warm braw that blows out air channel 290 and blow out downwards from air conditioner, arrive near the floor, near the heating underfooting, make the indoor comfortable environment that becomes.At this moment, the inner face wind direction face 291b when the upside up-down wind direction board 291 of blow-off outlet 29 is closed comes the front, and this face user can see.This looks like the above is the curved surface that gently becomes convex, more to bottom lateral bending song more inwards, stays the impression that wind direction is assembled and blown out towards the inboard downwards.Desirable wind direction when this impression turns round with heating installation is consistent, and the user thinks that just carrying out heating installation with required wind direction turns round.Actual wind direction is also downward, and the user can not feel confused.
At this moment, the wind direction face 291a of the inboard of upside up-down wind direction board 291 becomes the big convex surface of curvature, if this face is seen by the user, then produce wind and swarm next impression to the front side along curved surface, but wind direction face 291a that should the inboard is covered and can not seen by the user that by front side wind direction face 291b the user can not stay false impression.
In addition, the air conditioner of embodiment, when making above-mentioned up-down wind direction board the most downward, the upper wall in air channel does not contact with up-down wind direction board.
In general, the room temperature during the heating installation running is poor with the warm braw temperature that blows out, and the room temperature during than cold air operation is also big with the difference of the cold wind temperature that blows out.Therefore, if wind direction board is made the amount of movement of the heat between the hollow wind direction face that reduces the surface and the back side, then the temperature difference between the wind direction face at the surface and the back side becomes big, produces the phenomenon of up-down wind direction board deflection owing to the difference of thermal expansion.Like this, because of this temperature difference is little, the amount of deflection is little and do not become problem during cold air operation, and brings the effect that suppresses dewfall, but needs to consider the phenomenon of the deflection that caused by temperature difference when heating installation turns round.
In addition, by up-down wind direction board being made the hollow effect that makes hollow part play air adiabatic, the heat that can reduce between the wind direction face at the surface of up-down wind direction board and the back side moves.
Warm braw blows out downwards during the heating installation running, makes the indoor comfortable state that becomes immediately.At this moment, warm braw blows on the wind direction face of inboard of up-down wind direction board, makes air-flow downward.Therefore, the temperature of inboard wind direction face rises, and wind direction face near the front side of room air between produce temperature difference.The inboard wind direction face of up-down wind direction board and the heat between the wind direction face of front side move because by up-down wind direction board being made hollow the minimizing, so this temperature difference further increases.
If this temperature difference is excessive, then the surface of up-down wind direction board and the back side diminish outward appearance greatly because of the bending deformation that thermal expansion difference causes.
According to the air conditioner of embodiment, when making above-mentioned up-down wind direction board the most downward, the upper wall in air channel does not contact with up-down wind direction board.
Thus, warm braw also flows through in the gap between the topmost of the upper wall in air channel and up-down wind direction board, also spreads to the front side of up-down wind direction board.Therefore, the wind direction face of the front side of up-down wind direction board also is heated, and temperature rises, and the temperature difference between the wind direction board at the surface of up-down wind direction board and the back side is reduced, and the deflection that is caused by temperature difference also reduces.
In addition, when cold air operation, though can think that to make the downward situation of up-down wind direction board so less, in this case, cold wind also flows through in the gap between the topmost of the upper wall in air channel and up-down wind direction board, also spreads to the front side of up-down wind direction board.Therefore, the wind direction face of the front side of up-down wind direction board is covered by the low cold wind of absolute humidity, stops the high room air of absolute humidity and the preceding side contacts of up-down wind direction board, and the front side that is suppressed at up-down wind direction board produces dewfall.Like this, when cold air operation, also can suppress up-down wind direction board and be polluted by dewfall, or owing to around falling of dewfall pollute.
Therefore, can be provided in the air conditioner that also can keep the outward appearance of blow-off outlet in the running well.
As above explanation, in the wall-hanging air conditioner of the divergence type that can roughly close blow-off outlet with a plurality of up-down wind direction boards, possesses the expansion section that blows out the air channel that enlarges upward in the downstream, with the front portion that when closing, is positioned at this expansion section and central portion have at surface and the back side convex the wind direction face and also inner be hollow upside up-down wind direction board, the average curvature of the wind direction face outside becoming when having closed this upside up-down wind direction board is bigger than the average curvature of other wind direction faces of up-down wind direction board, below this wind direction face that becomes the outside becomes, and this upside up-down wind direction board is being arranged to become the back when downward when this upside up-down wind direction board is arranged to horizontal direction.
When having stopped air conditioner, the upside up-down wind direction board is contained in the expansion section that blows out the air channel, and its profile is made shape slick and sly continuously from the front panel to the bottom, can make the appearance design that does not have unnecessary concavo-convex smoothness, can not upset the atmosphere of interior decoration.
If from this air conditioner of indoor observation, then when heating installation turns round, from tiltedly down seeing the up-down wind direction board that erects with subvertical angle roughly, can see the convex surface in the outside of up-down wind direction board, intuitively produce and blow out that air-flow is induced by convex surface and towards the impression of below, this is consistent with actual wind direction and do not have inharmonic sensation, can not produce puzzlement.
In addition, when cold air operation, because from tiltedly seeing the up-down wind direction board of roughly being arranged to level down, so can see the convex surface of the downside of up-down wind direction board, intuitively produce the impression blow out that air-flow is induced by convex surface and to make progress a little from level, this is also consistent with actual wind direction and do not have inharmonious sense, can not produce puzzlement.At this moment, though the upside of up-down wind direction board also becomes convex surface, because the convex surface of ratio of curvature downside is little, therefore protruding degree is little but as mentioned above,, and, because up-down wind direction board is in level or downward a little posture, so almost can't see the convex surface of upside, only notices the convex surface of downside, as mentioned above, stay the impression that air-flow makes progress a little from level.
And the position when having closed this upside up-down wind direction board is in the position in the way of face of approximate horizontal of bottom surface that the in the past subvertical face of panel carries out the transition to air conditioner, and the curvature of its profile need be made than bigger with the continuous part in top or rear.Therefore, as mentioned above, it constitutes, and makes the face that becomes the outside when having closed up-down wind direction board become the wind direction face of downside when up-down wind direction board is arranged to level.
Thus, the protruding degree of the wind direction face below becoming when up-down wind direction board is arranged to level becomes big, and the described air-flow that blows out when producing cold air operation as mentioned above is suitable from the impression that level makes progress a little.
At this moment, though when up-down wind direction board is arranged to level, reduced to become the protruding degree of the wind direction face of upside, but as mentioned above, when up-down wind direction board is arranged to level, except being difficult to see the top curved surface, by doing like this, make the thickness attenuation of up-down wind direction board, wind speed at blow-off outlet does not have too big raising, can suppress flowing resistance, the raising of realizability energy and the reduction of noise.
In addition, blow out the expansion section, top in air channel, can control wind direction,, can add the function of the deodorizing of air conditioner inside and drying etc. by causing short circuit wittingly more towards the top by setting.
And, by up-down wind direction board being made hollow the wind direction face at the surface and the back side is made convex, and realize lightweight.Thus, the deflection of the up-down wind direction board in the time of can reducing to use air conditioner, and improve outward appearance.And, hollow by making, also have the transmission that reduces the heat in up-down wind direction board, and the effect of the dewfall when suppressing cold air operation.
Therefore, can obtain when not using, almost eliminating the concavo-convex of outside, can not upset the atmosphere of interior decoration, and the impression of the wind direction of the intuition of the direction that blows out air-flow when using when seeing up-down wind direction board is consistent and do not have inharmonic sensation, thereby can not produces puzzled air conditioner.
In addition, when having closed above-mentioned a plurality of up-down wind direction board, the wind direction face of the profile from the bottom surface of air conditioner to front panel below becoming when the cold air operation of up-down wind direction board forms sleekly.
Have again, when having stopped the running of air conditioner, have the control device of closing above-mentioned up-down wind direction board.
When having stopped air conditioner, up-down wind direction board is contained in the expansion section that blows out the air channel, and its outer shape of making continuous slyness from the front panel to the bottom becomes the appearance design that does not have unnecessary concavo-convex smoothness.
Therefore, can obtain when running stops, also can not upsetting the air conditioner of the atmosphere of interior decoration.
In addition, when making above-mentioned up-down wind direction board be in the posture of approximate horizontal, the distance from downstream to maximum ga(u)ge is shorter than the distance from upstream extremity to maximum ga(u)ge.
When the more cold air operation of the situation of the horizontal direction of up-down wind direction board being arranged to be easy to generate deflection, the downstream of up-down wind direction board becomes the front side and sees easily, but downstream thickness is thick, the intensity grow, and deflection diminishes, and can suppress the distortion that can see.On the other hand, the upstream extremity thin thickness of up-down wind direction board, weak strength, the deflection quantitative change is big.But upstream extremity is owing to the inboard that is positioned at air conditioner, so its distortion is unshowy, can not cause the deterioration of outward appearance.
The air conditioner that therefore, also can keep the outward appearance of blow-off outlet in can obtaining turning round well.
In addition, the pillar that supports above-mentioned up-down wind direction board is located at upstream extremity one side above.
Near the part expansion of the thin thickness of upstream extremity, flexural strength is little, and the distortion that deflection becomes big upstream extremity easily also diminishes.
Therefore, can obtain the air conditioner that outward appearance keeps more well.
In addition, when making above-mentioned up-down wind direction board the most downward, the upper wall in air channel does not contact with up-down wind direction board.
Warm braw had both flow through in the gap between the topmost of the upper wall in air channel and up-down wind direction board, also spread to the front side of up-down wind direction board.Therefore, the wind direction face of the front side of up-down wind direction board also is heated, and temperature rises, and the temperature difference between the surface of up-down wind direction board and the wind direction board at the back side reduces, and the deflection that is caused by temperature difference also reduces.
In addition, when cold air operation, though can think that to make the downward situation of up-down wind direction board so less, cold wind had both flow through in the gap between the topmost of the upper wall in air channel and up-down wind direction board in this case, also spread to the front side of up-down wind direction board.Therefore, the wind direction face of the front side of up-down wind direction board is covered by the low cold wind of absolute humidity, stops the high room air of absolute humidity and the preceding side contacts of up-down wind direction board, and the front side that is suppressed at up-down wind direction board produces dewfall.Like this, when cold air operation, also can suppress up-down wind direction board and be polluted by dewfall, or falling around the pollution owing to dewfall.
Therefore, can obtain the on-stream air conditioner that also can keep the outward appearance of blow-off outlet well.
