The specific embodiment
For the optimal way that carries out an invention
Below, one side is with reference to Fig. 1~Fig. 3, and one side describes the air conditioner of relevant embodiments of the present invention in detail.Fig. 1 is that the wind direction control of blow-off outlet of air conditioner of the relevant embodiments of the present invention of expression is with the figure of the formation of shutter.Fig. 2 is that the expression of relevant present embodiment has the sketch of the wind direction control of heat-barrier material with the structure of shutter.Fig. 3 is the figure of general formation of the air conditioner of the relevant present embodiment of expression.
At first, one side is with reference to Fig. 3, and one side is summarized the general formation of the air conditioner of relevant embodiments of the present invention.The 31st, the beam of building, the 32nd, ceiling floor, 33 are arranged on the air conditioner main body between beam 31 and the ceiling floor 32, and the 34th, be fixed on the anchoring bolt on the beam, the 35th, the decoration panel of the peristome of sealing ceiling floor 32 and the lower open end of air conditioner main body 33.
The suction inlet 37 that possesses filter 36 central portion being provided with of decoration panel 35, and has a blow-off outlet 41, this blow-off outlet 41 possess be configured in suction inlet around the four directions to wind direction control with shutter (wind direction board) 42, on the path that connects suction inlet 37 and blow-off outlet 41, fan motor 38 is set, Air Blast fan 39 and heat exchanger 40, carried out heat exchange from the indoor air that suction inlet 37 sucks by heat exchanger 40 by Air Blast fan 39, send to indoor with shutter (wind direction board) 42 by wind direction control from blow-off outlet 41.
In Fig. 1 and Fig. 2, the air conditioner of relevant present embodiment possesses the air conditioner body shell 1 (hereinafter referred to as body shell) that is embedded in the ceiling; Be arranged on the decoration panel 6 on the bottom surface of body shell 1; Be arranged on the substantial middle portion of decoration panel 6, room air be drawn into the suction inlet 3 of the inside of body shell 1; Be arranged on four limits on every side of suction inlet 3, to the blow-off outlet 4 of indoor blow out air; Be arranged on the wind direction control shutter 2 (hereinafter referred to as shutter) on the blow-off outlet; A distolateral rotating shaft 5 that is arranged on that shutter 2 rotates; Loading spring 7 to the loading of axial rotary shutter closing direction; Drive the motor 10 of rotating shaft 5.
Here, be arranged on suction inlet 3 around blow-off outlet 4 on four limits, in four bights (corner portion) of separately four limit quadratures, blow-off outlet 4 is not set.Therefore, in existing technology, changes in temperature wind can not arrive therewith indoor that four bights face.In embodiments of the present invention, by the structure at the shutter shown in Fig. 2, changes in temperature wind also can arrive the indoor location of facing with four bights, its details aftermentioned.
The supporting position of shutter 2 decoration panel 6 of (towards a side of suction inlet 3) in the inboard that is arranged on blow-off outlet 4, undertaken freely rotating by rotating shaft 5, be can be from the inboard (towards a side of suction inlet 3) of rotating shaft 5 from the changes in temperature wind of air conditioner main body, promptly the rear side of shutter be led to indoor structure.In addition, in general air conditioner shown in Figure 3, the inboard of shutter 42 (rear side) and the outside (towards a side of the periphery of decoration panel 35, i.e. the pressure face side of shutter) has the space that changes in temperature wind passes through.The shutter 2 of relevant present embodiment is the so-called cantilevered construction that is formed by the rotating shaft 5 on the supporting position of decoration panel 6, because be this structure, so, the shutter length from blow-off outlet 4 inboards to the outside of shutter 2 is (the illustrated example of Fig. 1, length from the left end of shutter 2 to right-hand member, or with the length of the direction of rotating shaft 5 quadratures of shutter 2) longer with comparing of Fig. 3.
In addition, other reason that the length of shutter 2 is prolonged be because, aperture at shutter 2 arrives maximum aperture (from horizontal level 35 degree~55 degree of ceiling floor, 40 degree~50 degree preferably) time (in the illustrated example of Fig. 1, the double dot dash line of lower gear), the changes in temperature wind that lowers along body shell 1 conflicts with shutter 2, and, flow along the shutter shape, blow out to indoor with its flow velocity, can be to flowing under blow-off outlet 4.If under to flowing, then this flows and will form short circuit directly around going in suction inlet 3, for anti-short circuit here, the length of shutter 2 is prolonged.In addition because if blow out air under to flowing, then changes in temperature wind directly blows to the human body that is positioned at this position and brings harmful effect, so, also be for fear of this situation.
With reference to Fig. 1, illustrated L1 is the length of the orthogonal direction of the rotating shaft 5 in the blow-off outlet 4, and illustrated L2 is the equidirectional length in the shutter 2.Shutter 2 is that fulcrum rotates with rotating shaft 5, constitutes in its another distolateral mode that can be opened to maximum shutter angle θ max (for example, the shutter aperture of the lower gear of Fig. 1) from the position (horizontal level of ceiling face) of stopping up above-mentioned blow-off outlet; When air-conditioner operation,, be carried out aperture control thus constituting to the mode of rotating between the maximum shutter aperture θ max from minimum shutter aperture θ min (for example, the middle-grade shutter aperture of Fig. 1).And, minimum shutter aperture θ min constitutes in such a way: even when minimum shutter aperture θ min, also can suppress the wall attachment effect that reason causes in blow out air and on the ceiling face, produce stain, specifically, this shutter aperture, its θ min is 15 °~30 °, preferably 20 °~30 °, its θ max is 35 °~55 °, preferably 40 °~50 °.
The blow out air that lowers from the outermost of the blow-off outlet of body shell 1 conflicts with the shutter 2 of the aperture of θ max, and moving along the surface current of shutter 2, and such shutter length is one of feature of present embodiment.That is, as shown in Figure 1, made following length: with the maximum shutter aperture θ max shown in the double dot dash line, from the vertical line of the single-point line of the outermost of the blow-off outlet of body shell 1 in the inboard of the open ora terminalis (front end) of shutter 2 intersection.From then on extend to the great degree in crosspoint the length of shutter 2, it is the size that does not produce to the short circuit of suction inlet 3, preferably make when minimum shutter aperture θ min, the shutter front end is compared with the outermost of blow-off outlet and is positioned at the outside (for example, the lateral surface with body shell 1 is in a ratio of outer direction) such length more fully.If increase the length of shutter in this wise, then the air from blow-off outlet can be diffused into equably farly along shutter, can suppress non-uniform temperature.Particularly, because when minimum shutter aperture θ min, can be far with delivering in general horizontal direction along shutter from the air of blow-off outlet, so, can avoid changes in temperature wind directly to blow to being positioned at the human body of below reliably, can prevent because of contact the unplessantness displeasure that produces with wind.
In addition, minimum shutter aperture θ min is preferably made the angle of the stain that can suppress the ceiling face that produces because of wall attachment effect.Here, the stain of the ceiling face that produces because of wall attachment effect is meant, if the air that comes out along the surface current of shutter 2 then produces negative pressure by the position near ceiling between this is by air and ceiling, airborne dirt is attached to the phenomenon on the ceiling.Even because under the situation of the aperture of θ max, it also is structure with shutter of the length longer than the crosspoint of intersecting with single-point shown in Figure 1 line vertical line, so, when θ min, the open ora terminalis of shutter 2 and the interval between the ceiling face increase, therefore, can further bring into play stain and suppress effect.In addition, the shutter aperture that performs most shown in Figure 1 is illustrated in the situation of having closed shutter 2 when air conditioner stops.On the part of the above-mentioned decoration panel of the roughly pars intermedia between the outermost of the most external of decoration panel 6 and blow-off outlet 4, formed depression, under the state of having closed above-mentioned shutter 2, because make the shutter front end come in the part of above-mentioned depression of decoration panel 6, institute is not so that shutter can stretch out from decoration panel.That is, under the state of having closed shutter, make the shutter back side and decoration panel surface roughly become same plane, and make the shape of decoration panel 6 integral body change sleekly, thereby also improved appearance design.
Explain, when shutter 2 being carried out angle initialization with certain certain angle for the horizontal level of ceiling face, (compare) if the shutter length of rotating shaft direct cross direction (short side direction) is lacked as conventional example with the shutter of length in the present embodiment, then producing blow out air increases around the possibility of going into the short circuit effect in the suction inlet 3, if avoid this situation and reduce rotational angle, then be easy to generate wall attachment effect.To this, in the present embodiment, because the shutter aperture (θ max) at lower gear shown in Figure 1 has the shutter length that does not produce the short circuit effect, so, even middle-grade shutter aperture (θ min) at Fig. 1, distance between open ora terminalis of shutter and the ceiling face also increases, and is difficult to produce wall attachment effect.
And, with reference to Fig. 1, viewpoint according to the length dimension L2 (the equidirectional length in the shutter 2) of the length dimension L1 (length of the orthogonal direction of the rotating shaft 5 in the blow-off outlet 4) of blow-off outlet 4 and shutter 2 describes, if enumerate concrete numerical example (do not produce above-mentioned short circuit effect and be difficult to produce the concrete structure example of wall attachment effect), L1=66.5mm then, L2=106mm, their ratio L2/L1=1.59.Various result of experiment show, L2/L1 is 1.6 optimum, are 1.4~1.8 can access good result.
Shutter 2, by imposing on the control input signal of motor 10, its motor drive shaft rotation relies on this motor drive shaft rotation, and rotating shaft 5 rotates, and thus, the aperture of shutter 2 is carried out adjustment.The rotating fulcrum of shutter 2 is the most inboard blow-off outlet 4, and changes in temperature wind is not in a ratio of an interior side (shutter rear side) from rotating fulcrum therewith to be passed through.Making structure as described above is the lower side that directly blows to air conditioner for fear of changes in temperature wind.For the people of the lower side that is sitting in air conditioner, strong changes in temperature wind directly blows and bad from air conditioner, but wish by from around changes in temperature wind freeze indirectly, heat.And if also be the lower side that is blown out to air conditioner for fear of changes in temperature wind, then this changes in temperature wind that blows out is directly around going in suction inlet 3, thus make refrigeration, situation that the efficient that heats reduces.
Among Fig. 2 and Fig. 4, shutter 2 is made of the heat-barrier material 8 that shutter main body 12 and dismounting are mounted freely on the shutter main body 12, shutter main body 12, as shown in Figure 4, with the end of rotating shaft 5 as a side; The opposing party's end (being the lower end in the illustrated example of Fig. 4) is the open end, from direct cold warm braw here, make it to flow into indoor, in addition, heat-barrier material 8 is spongy, by the bubble performance effect of heat insulation of sponge inside, with regard to material, foamed resin is an example, constitutes by carrying out some deformed configurations.On shutter main body 12 shown in Figure 4, the heat-barrier material 8 of even shape (rectangular cubic shaped) and the space that is formed between stop component 9 (about end) and the shutter main body 12 is chimeric, made structure with shutter main body 12 one.
Shutter 2 in the present embodiment is owing to be to be the cantilevered construction of center of rotation with rotating shaft 5, and be the structure that blow out air does not pass through from the inboard (shutter rear side) of rotating shaft, so, have when refrigeration and contact the possibility that produces dewfall in shutter surface (indoor) with shutter the inside (the air conditioner main body side of shutter) because of cold wind, for fear of this dewfall, heat-barrier material 8 is set in the face side (pressure face side) of shutter 2.
The structure that the one of heat-barrier material 8 will be installed on shutter main body 12 is illustrated among Fig. 2.Because the left and right end portions in shutter main body 12 has the stop component 9 that embeds heat-barrier material 8, so even do not use bonding agent, adhesives, also can easily install by heat-barrier material 8 is embedded, the replacing operation of heat-barrier material 8 also becomes easy.
In Fig. 2 of expression shutter unitary construction, represent the flow direction of changes in temperature wind by arrow.Though the changes in temperature wind butt shutter 2 that lowers from the air conditioner main body, changed its flow direction, but, if shutter in the past, then the length direction of changes in temperature wind and shutter flows abreast, but in the present embodiment, the flow direction of changes in temperature wind is can resolve into the changes in temperature wind flow composition parallel with the length direction of shutter 2 (length direction of shutter 2 flow composition) and with its length direction quadrature and to the flow direction of the changes in temperature wind flow composition of motor-side 10 or loading spring 7 sides (width of shutter 2 flow composition).The latter's changes in temperature wind flow become to be divided into changes in temperature wind arrive with the bight (corner portion) of the blow-off outlet 4 on four limits face mutually indoor mobile.
The width that the flow direction of the changes in temperature wind in the present embodiment has shutter 2 (is left and right directions in the illustrated example of Fig. 2, being the direction of rotating shaft 5) composition flows, this is because the central portion of the shutter width of the heat-barrier material 8 that changes in temperature wind directly conflicts swells, and from then on bump produces along the shape that left and right directions tilts to reduce.That is, as shown in Figure 2,, can access the effect of diffusion to the left and right that flows of blow out air by the shape of the central portion protuberance that makes shutter 2 and the tilted shape that reduces to the left and right, so as expansion in the horizontal direction about blow out scope.
As the projecting shape that forms this central portion and about the concrete example of reduction tilted shape of portion be, its width uprightly is provided with rib 50 intermittently in shutter main body 12 upper edges, and make the height of rib 50 of central portion of width the highest, right-hand member reduces successively left.Heat-barrier material 8 having chimeric flat cuboid on the shutter main body 12 of such rib 50 constitutes shutter 2.By from central portion left right-hand member reduce the height of rib 50 successively, with blow out air flow with towards about the mode channeling conduct of end.The function of rib 50, as mentioned above, be by its height is reduced gradually at width, make the flow direction of blow out air become with four jiaos of directions of facing mutually of blow-off outlet 4 blow out, in addition because shutter 2 is cantilevered construction, so being accompanied by shutter length increases, have the possibility that shutter 2 vibrates because of blow out air, so this also is that shutter main body 12 is strengthened, so that anti-vibration here.
In addition, be not limited on shutter main body 12, be provided with rib 50 with difference of height, also can not have on the shutter main body 12 of rib 50, chimeric central portion swell forms shutter 2 at the heat-barrier material 8 of such shape that width (left and right directions) reduces successively.And, also can be irrelevant with having or not of heat-barrier material 8, be the such shape that makes the central portion protuberance and reduce successively of being configured to of shutter 2 self at width (left and right directions).
The rib 50 that is arranged on the shutter main body 12 reduces ground formation to the left and right successively from central portion, still, also reduces gradually to the open end from rotating shaft 5.This structure that reduces gradually is to flow into indoor swimmingly for feasible blow out air from the air conditioner main body.
Be wound on the loading spring 7 on the rotating shaft 5 of shutter main body 12 shown in Figure 2, because the length (length from the rotating shaft to the open end) of shutter 2 prolongs, the clockwise revolving force of Fig. 1 increases because of the blast from the changes in temperature wind of air conditioner main body, so, be the parts that are used to resist this revolving force.Though by motor 10 shutter 2 is remained on certain aperture,, with the rotating shaft 5 of motor 10 opposition sides on be subjected to the blast of changes in temperature wind, the shutter 2 of this part is subjected to the power desiring to open, but loading spring 7 plays a role in the mode of resisting this power.
In other words, because in air-conditioner operation, with rotating shaft 5 is fulcrum, making shutter 2 when blow to level downwards and blow (to the direction of body shell 1 side closure) and be rotated, by all bearing blow out air, the power of bearing blow out air above the shutter, so, for auxiliary rotation torque loading spring 7 is set, thus, has and alleviate the effect of closing the rotation driving torque when the shutter 2.In addition, the shutter 2 when air conditioner is stopped can being kept closing state securely by the power that acts on closing direction of loading spring 7 when body shell 1 side closure is taken in.
In addition, in the above-described embodiment, air conditioner is illustrated for the situation of four directions to indoor set, still, the present invention is not limited to this, even two direction indoor sets etc. also can similarly be implemented.
