The specific embodiment
For the optimal way carrying 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 by the formation of shutter.Fig. 2 is that the expression of relevant present embodiment has the sketch of the structure of shutter for the wind direction control of heat-barrier material.Fig. 3 means the figure of general formation of the air conditioner of relevant present embodiment.
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 sealing peristome of 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 there is blow-off outlet 41, this blow-off outlet 41 possess the surrounding four directions that is configured in suction inlet 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, the indoor air being sucked from suction inlet 37 by Air Blast fan 39 carries out heat exchange by heat exchanger 40, from blow-off outlet 41, by wind direction, is controlled with shutter (wind direction board) 42 and is sent 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) being embedded in 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 surrounding four limits of suction inlet 3, to the blow-off outlet 4 of indoor blow out air; The wind direction being 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; The loading spring 7 that axial rotary shutter closing direction is loaded; Drive the motor 10 of rotating shaft 5.
Here, be arranged on the blow-off outlet 4 on surrounding four limits of suction inlet 3, in four bights (corner portion) of four limit quadratures separately, blow-off outlet 4 be 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 at the shutter shown in Fig. 2, cold air also can arrive the indoor location of facing with four bights, its details aftermentioned.
Shutter 2 is being arranged on the supporting portion of the decoration panel 6 of the inner side of blow-off outlet 4 (towards a side of suction inlet 3), by rotating shaft 5, carry out free rotation, be can be from the inner side (towards a side of suction inlet 3) of rotating shaft 5 from the cold air of air conditioner main body, the rear side of shutter be led to indoor structure.In addition, in the general air conditioner shown in Fig. 3, the inner side of shutter 42 (rear side) and 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 being formed by the rotating shaft 5 in the supporting portion at decoration panel 6, because be this structure, so, the shutter length from blow-off outlet 4 inner sides to 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 lowering along body shell 1 conflicts with shutter 2, and, along shutter shape, flow, 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 and is positioned at the human body of 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 be take rotating shaft 5 as fulcrum rotation, for example, in its another distolateral mode that can be opened to from stopping up the position (horizontal level of ceiling face) of above-mentioned blow-off outlet maximum shutter angle θ max (, the shutter aperture of the lower gear of Fig. 1), form; When air-conditioner operation, can, for example, forming to the mode of rotating between maximum shutter aperture θ max from minimum shutter aperture θ min (, the middle-grade shutter aperture of Fig. 1), being carried out aperture thus and control.And, minimum shutter aperture θ min forms in such a way: even when minimum shutter aperture θ min, the wall attachment effect that also can suppress because causing due to blow out air produces stain on 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 lowering 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 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 inner side of the open ora terminalis (front end) of shutter 2.From then on the length that the great degree in crosspoint ground extends shutter 2, it is the size not producing to the short circuit of suction inlet 3, preferably make when minimum shutter aperture θ min, shutter front end is compared with the outermost of blow-off outlet and is positioned at more fully outside (for example, being in a ratio of outer direction with the lateral surface of body shell 1) 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, the human body that can avoid reliably cold air directly to blow to being positioned at below, can prevent because contact the unplessantness displeasure producing 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 producing because of wall attachment effect refers to, if along the surface current of shutter 2 air out by the position near ceiling, between this is by air and ceiling, produce negative pressure, airborne dirt is attached to the phenomenon on ceiling.Even due in the situation that the aperture of θ max, also be the structure with the shutter of the longer length in the crosspoint more crossing than the single-point line vertical line with shown in Fig. 1, so, when θ min, the open ora terminalis of shutter 2 and the interval between ceiling face increase, therefore, can further bring into play stain inhibition.In addition, the shutter aperture performing most shown in Fig. 1 is illustrated in the situation of having closed shutter 2 when air conditioner stops.In the part of the above-mentioned decoration panel of the roughly pars intermedia between the most external of decoration panel 6 and the outermost of blow-off outlet 4, formed depression, closing under the state of above-mentioned shutter 2, because shutter front end is 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, closing under the state of shutter, making the shutter back side and decoration panel surface roughly become same plane, and the shape of decoration panel 6 integral body is changed sleekly, thereby also improving appearance design.
Explain, when certain certain angle for the horizontal level with respect to ceiling face carries out angle initialization to shutter 2, if as conventional example, the shutter length of rotating shaft direct cross direction (short side direction) is short (comparing with the shutter of length in present embodiment), producing blow out air increases around the possibility entering to the short circuit effect in suction inlet 3, if reduce rotational angle for fear of this situation, easily produce wall attachment effect.To this, in the present embodiment, because the shutter aperture (θ max) at the lower gear shown in Fig. 1 has the shutter length that does not produce 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 of blow-off outlet 4 (length of the orthogonal direction of the rotating shaft 5 in 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, relies on this motor drive shaft rotation, and rotating shaft 5 rotates, and thus, the aperture of shutter 2 is adjusted.The rotating fulcrum of shutter 2 is in the inner side of 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 for fear of cold air, directly to blow to the lower side of air conditioner.For being sitting in the people of the lower side of air conditioner, strong cold air directly blows also bad from air conditioner, but wishes by indirectly freezing, heat from cold air around.And if be to be also blown out to the lower side of air conditioner for fear of cold air, this cold air blowing 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, the heat-barrier material 8 that shutter 2 is mounted freely in shutter main body 12 by shutter main body 12 and dismounting forms, shutter main body 12, as shown in Figure 4, the end using 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.In the shutter main body 12 shown in Fig. 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 to take the cantilevered construction that rotating shaft 5 is center of rotation, and be the structure that blow out air does not pass through from the inner side (shutter rear side) of rotating shaft, so, have when refrigeration because cold wind contacts with shutter the inside (the air conditioner main body side of shutter) possibility that produces dewfall on shutter surface (indoor), for fear of this dewfall, in the face side (pressure face side) of shutter 2, heat-barrier material 8 is set.
The structure that the one of heat-barrier material 8 has been installed in shutter main body 12 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 if do not use bonding agent, adhesives, by heat-barrier material 8 is embedded and also can easily be installed, the replacing operation of heat-barrier material 8 also becomes easy.
In representing Fig. 2 of blind integrated structure, by arrow, represented the flow direction of cold air.Although the cold air butt shutter 2 lowering from 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 flow direction of composition (width of shutter 2 flow composition) of the cold air of motor-side 10 or loading spring 7 sides 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 portion) 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 the shape that from then on bump tilts to reduce along left and right directions produces.That is, as shown in Figure 2, by making the shape of central portion protuberance of shutter 2 and the tilted shape reducing to the left and right, can access the effect of diffusion to the left and right that flows of blow out air, so that expansion left and right in the horizontal direction blows out scope.
As the concrete example that forms the projecting shape of this central portion and the reduction tilted shape of left and right portion, be, in shutter main body 12, along its width, rib 50 is uprightly set intermittently, and make the height of rib 50 of central portion of width the highest, right-hand member reduces successively left.At the heat-barrier material 8 with chimeric flat cuboid in 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 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, there is 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 in shutter main body 12, also can not have in the shutter main body 12 of rib 50, the heat-barrier material 8 of such shape that chimeric central portion swell reduces successively at width (left and right directions) forms shutter 2.And, also can be irrelevant with having or not of heat-barrier material 8, be the such shape that makes central portion protuberance and reduce successively at width (left and right directions) of being configured to of shutter 2 self.
The rib 50 being arranged in shutter main body 12 reduces successively to the left and right and forms from central portion, still, from rotating shaft 5, to open end, also reduces gradually.This structure reducing is gradually from the blow out air of air conditioner main body, to flow into swimmingly indoor in order to make.
Be wound on the loading spring 7 on the rotating shaft 5 of the shutter main body 12 shown in Fig. 2, length (length from rotating shaft to open end) prolongation due to shutter 2, the clockwise revolving force of Fig. 1 increases because of the blast of the cold air from air conditioner main body, so, be for resisting the parts of this revolving force.Though by motor 10, shutter 2 is remained on to certain aperture,, on the rotating shaft 5 with motor 10 opposition sides, be subject to the blast of cold air, the shutter 2 of this part is subject to the power of wanting to open, loading spring 7 plays a role to resist the mode of 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, when the shutter 2 when air conditioner is stopped is taken in to body shell 1 side closure, can maintain the state of closing securely by the power that acts on closing direction of loading spring 7.
In addition, in the above-described embodiment, to air conditioner, be that the cubic situation to indoor set is illustrated, still, the present invention is not limited to this, even two direction indoor sets etc. also can similarly be implemented.
