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 means that the wind direction of blow-off outlet of the air conditioner of relevant embodiments of the present invention controls the figure with 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 means the figure of general formation of the air conditioner of relevant present embodiment.
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 ceiling floor 32, and the 34th, be fixed on the anchoring bolt on 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 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, from blow-off outlet 41, by wind direction, control with shutter (wind direction board) 42 and send to indoor.
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 ceiling; Be arranged on the decoration panel 6 on the bottom surface of body shell 1; Be arranged on the substantial middle section 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; The wind direction that is arranged on blow-off outlet is controlled with shutter 2 (hereinafter referred to as shutter); 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 section) of separately four limit quadratures, blow-off outlet 4 is not set.Therefore, in existing technology, cold air can not arrive therewith indoor that four bights face.In embodiments of the present invention, by the structure of the shutter shown in Fig. 2, cold air also can arrive the indoor location of facing with four bights, its details aftermentioned.
The supporting portion 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, carry out free rotation by rotating shaft 5, be can be from the inboard (towards a side of suction inlet 3) of rotating shaft 5 from the cold air of air conditioner main body, namely 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 cold air 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 portion at 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, make other reason that the length of shutter 2 extends be because, aperture at shutter 2 arrives maximum aperture (35 degree~55 degree from the horizontal level 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 cold air that lowers along body shell 1 conflicts with shutter 2, and, flow along the shutter shape, with its flow velocity, to indoor, blow out, not can under blow-off outlet 4 to flowing.If under to flowing, this flow will directly around entering in suction inlet 3, form short circuit,, for anti-short circuit here, make the length prolongation of shutter 2.In addition, if due to blow out air under to flowing, cold air directly blows to the human body that is positioned at this position and brings harmful effect, so, be also 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 blow-off outlet 4, and illustrated L2 is the equidirectional length in shutter 2.Shutter 2 rotates take rotating shaft 5 as fulcrum, form in its another distolateral mode that can be opened to from the position (horizontal level of ceiling face) of stopping up above-mentioned blow-off outlet maximum shutter angle θ max (for example, the shutter aperture of the lower gear of Fig. 1); When air-conditioner operation,, forming to the mode of rotating between maximum shutter aperture θ max from minimum shutter aperture θ min (for example, the middle-grade shutter aperture of Fig. 1), be carried out thus aperture and control.And, minimum shutter aperture θ min forms 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 produce stain on the ceiling face, 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: at the maximum shutter aperture θ max with shown in double dot dash line, the dashdotted vertical line of list from the outermost of the blow-off outlet of body shell 1 intersects in the inboard of the open ora terminalis (front end) of shutter 2.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 more fully the outside (for example, with the lateral surface of body shell 1, being in a ratio of outer direction) such length.If increase in this wise the length of shutter, 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, the air from blow-off outlet can be delivered in general horizontal direction along shutter far, so, can avoid reliably cold air directly to blow to being positioned at the human body of below, can prevent because 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 refers to, if along the surface current air out of shutter 2 by the position near ceiling, produce negative pressure between this is by air and ceiling, airborne dirt is attached to the phenomenon on ceiling.Even due in the situation that the aperture of θ max, it is also the structure with shutter of the longer length in the crosspoint more crossing than the line of the single-point with shown in Figure 1 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 the stain inhibition.In addition, the shutter aperture that performs most shown in Figure 1 is illustrated in when air conditioner stops the situation of having closed shutter 2.Formed depression 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, 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 certain certain angle for the horizontal level with respect to the ceiling face carries out angle initialization to shutter 2, if the shutter length of rotating shaft direct cross direction (short side direction) is short as conventional example (with the shutter of length in present embodiment, comparing), producing blow out air increases around the possibility that enters to the short circuit effect in suction inlet 3, if avoid this situation and reduce rotational angle, easily produce wall attachment effect.To this, in the present embodiment, because the shutter aperture (θ max) of the lower gear shown in Figure 1 has the shutter length that does not produce the short circuit effect, so, even the middle-grade shutter aperture (θ min) at Fig. 1, distance between the open ora terminalis of shutter and 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 shutter 2) of the length dimension L1 (length of the orthogonal direction of the rotating shaft 5 in 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, L2=106mm, their ratio L2/L1=1.59.The result of various experiments shows, L2/L1 is 1.6 most suitable, is 1.4~1.8 can access good result.
Shutter 2, by imposing on the control inputs signal of motor 10, its motor drive shaft rotation, rely 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 cold air 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 directly to blow to the lower side of air conditioner for fear of cold air.For the people of the lower side that is sitting in air conditioner, strong cold air directly blows and bad from air conditioner, but wish by from around cold air indirectly freeze, heat.And if be also to be blown out to the lower side of air conditioner for fear of cold air, this cold air that blows out is directly around entering in suction inlet 3, thus make refrigeration, the situation of the Efficiency Decreasing that heats.
In Fig. 2 and Fig. 4, shutter 2 consists of the heat-barrier material 8 that shutter main body 12 and dismounting are mounted freely on 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 lower end in the illustrated example of Fig. 4) is open end, from guiding cold air 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, the structure that can carry out some distortion, consists of.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 (left and right end) and shutter main body 12 is chimeric, made the structure with shutter main body 12 one.
Shutter 2 in present embodiment is owing to being cantilevered construction take rotating shaft 5 as center of rotation, 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 with shutter the inside (the air conditioner main body side of shutter) possibility that produces dewfall on shutter surface (indoor) because of cold wind,, for fear of this dewfall, in the face side (pressure face side) of shutter 2, heat-barrier material 8 is set.
During the one of heat-barrier material 8 will be installed on shutter main body 12 structure is illustrated in 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, by heat-barrier material 8 is embedded and also can easily install, the replacing operation of heat-barrier material 8 also becomes easy.
In Fig. 2 of expression blind integrated structure, represented the flow direction of cold air by arrow.Although the cold air butt shutter 2 that lowers from the air conditioner main body, changed its flow direction, but, if shutter in the past, the length direction of cold air and shutter flows abreast, but in the present embodiment, the flow direction of cold air is to resolve into flow composition (length direction of shutter 2 flow composition) and with its length direction quadrature and to the flow direction of the mobile composition of the cold air of motor-side 10 or loading spring 7 sides (width of shutter 2 flow composition) of the cold air parallel with the length direction of shutter 2.The latter's cold air flow into be divided into cold air arrive with the bight (corner section) of the blow-off outlet 4 on four limits face mutually indoor mobile.
The width that the flow direction of the cold air in 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 cold air 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,, by the shape of the central portion protuberance that makes shutter 2 and the tilted shape that reduces to the left and right, can access the effect of diffusion to the left and right that flows of blow out air, so that the left and right that enlarges in the horizontal direction blows out scope.
Concrete example as the reduction tilted shape of the projecting shape that forms this central portion and left and right section is, along its width, rib 50 is set uprightly intermittently on shutter main body 12, 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, form shutter 2.By from central portion left right-hand member reduce successively the height of rib 50, flowing of blow out air guided in the mode towards the left and right end.The function of rib 50, as mentioned above, 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 is also that shutter main body 12 is strengthened, so that anti-vibration here.
In addition, be not limited to arrange the rib 50 with difference of height on shutter main body 12, 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 at width (left and right directions), reduce successively that is configured to of shutter 2 self.The rib 50 that is arranged on shutter main body 12 reduces ground formation to the left and right successively from central portion, still, from rotating shaft 5, to open end, also reduces gradually.This structure that reduces gradually is in order to make the blow out air from the air conditioner main body flow into swimmingly indoor.
Be wound on the loading spring 7 on the rotating shaft 5 of shutter main body 12 shown in Figure 2, length (length from the rotating shaft to the open end) prolongation due to shutter 2, the clockwise revolving force of Fig. 1 increases because of the blast of the cold air from the air conditioner main body, so, be the parts for this revolving force of opposing.Though by motor 10, shutter 2 is remained on certain aperture,, be subject to the blast of cold air on the rotating shaft 5 with motor 10 opposition sides, the shutter 2 of this part is subject to the power of wanting to open, loading spring 7 plays a role in the mode of resisting this power.
In other words, because in air-conditioner operation, take rotating shaft 5 as fulcrum, make shutter 2 from when blowing to level downwards and blow (to the direction of body shell 1 side closure) and being rotated, by all bearing blow out air, the power of bearing blow out air above shutter, so, for auxiliary rotation torque, loading spring 7 is set, thus, has and alleviate the effect of closing the rotary actuation moment of torsion when shutter 2.In addition, the shutter 2 when air conditioner is stopped can being kept the state of closing securely by the power that acts on closing direction of loading spring 7 when taking in to body shell 1 side closure.
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.
