Technical field.
Background technology
The blowing mouth of traditional ceiling built-in air-conditioning system is provided with the horizontal blade that the blowing direction of Air Conditioning can be changed up and down.When the warm operation of system, utilize blowing direction that this horizontal blade makes Air Conditioning relatively down, during refrigerating operaton then with near relative up with the parallel state of ceiling (so-called level blowing), under each running status, to make indoor temperature distribution even, improve air-conditioner efficiency.
But above-mentioned level blowing state makes the microgranular dust that contains in the Air Conditioning that blows out be attached on the ceiling sometimes and partly pollutes ceiling.Specifically, as shown in Figure 9, when horizontal direction is seen aircondition, the air that blows out from blowing mouth (a) with level blowing state is seen along its flow direction and is roughly V font, middle body at blow-off outlet (a) length direction, air to blow out initial velocity big, so air-flow flows in the zone of leaving ceiling (b).In addition, the microgranular dust inertia that contains in this blow out air is big, so be attached to hardly on the ceiling (b).
And in the two side portions of blowing mouth (a) length direction, air-flow spreads on the limit or forms the whirlpool, and it blows out the air-flow that initial velocity is lower than aforementioned middle body, so wall attachment effect makes air-flow flow along ceiling (b).And the dust inertia that contains in this blow out air is little, be attached to easily on the ceiling (b), so with zone (D) (see figure 2) of the approaching ceiling (b) in the both sides of blowing mouth (a) with airborne dust, dirty easily.
In order to prevent this dirt, the spy open in the flat 3-160266 communique that suggestion mounting or dismounting on horizontal blade are provided with auxiliary fin freely so that blowing direction towards the ceiling side shifting, dirty difficulty or ease can take place according to ceiling and install and remove in this auxiliary fin.The environment of dirty candle takes place or is that hospital is the sort of to preventing that dirt from requiring extra high place just will assist the fin dismounting in, ceiling easily many such as dust in room air, and, assist fin to carry out the level blowing with horizontal blade down at the environment that is difficult for the dirt of generation ceiling or to preventing that the dirty lower place of requirement from then can install.
But, even the auxiliary fin of aforementioned conventional example has been installed, in the environment that the ceiling dirt takes place easily etc., have to again remove, the Air Conditioning that the result causes blowing mouth to come out blows out always down, air-conditioner efficiency is low when causing doing the refrigerating operaton of level blowing, moreover, cold wind directly blows to indoor occupant, causes sense of discomfort.
Summary of the invention
In view of the above problems, the configuration structure etc. that the objective of the invention is to the blowing mouth of Air Conditioning is studied, and can obtain the blowing direction that the running status with aircondition adapts, and can prevent the dirt of ceiling again.
The present invention has adopted following scheme for solving foregoing problems.
The 1st scheme relates to ceiling built-in air-conditioning system, the bottom configured board member 14 of the aircondition body 10 in imbedding ceiling 70, on this panel member 14, the blowing mouth 16 that blows out Air Conditioning to this interior space is set towards the interior space, being provided with in this blowing mouth 16 simultaneously can be to the air ducting 18 of Air Conditioning blow-off direction channeling conduct, it is characterized in that, between aforementioned panel member 14 and ceiling 70, be provided with and regulate above-below direction cushion member 72 at interval, make to be in apart from ceiling 70 to reach place, below more than the 45mm by the foot of the panel member 14 of that side of aforementioned air ducting 18 guiding blowing directions.
Adopt this scheme, when refrigerating operaton etc., the Air Conditioning that blows out from the blowing mouth 16 of aircondition 1 becomes the jet flow that blows to the interior space by the guiding of air ducting 18, its jet flow axle because of wall attachment effect to ceiling 70 direction bendings.But guide the foot of the panel member 14 of blowing directions to be in ceiling 70 belows by aforementioned air ducting 18, apart from it more than 45mm, so so long as general cold air blast velocity, even the air-flow of the blowing mouth 16 length direction two side portions that the blowing initial velocity is lower, this air-flow can not arrive ceiling 70 yet, but because of and room air between temperature difference descend mobile.
Like this, parallel with ceiling to be similar to even the blow-off direction of Air Conditioning is made progress, air-flow also can not flow along ceiling, therefore can prevent the ceiling dirt under the so-called level blowing state.
Adopt this scheme, under antifouling demanding situation, can pass through the interval of 70 on cushion member 72 adjusting range board members 14 and ceiling to ceiling, promptly regulate the interval of 70 on blowing mouth 16 and ceiling, it be that below more than the 45mm is located that the foot that forms member with the blowing mouth that will guide the Air Conditioning blowing direction is set in really apart from ceiling 70.When antifouling requirement is low, when being set, aircondition 1 also can improve the associative perception of aircondition 1 and ceiling 70 like this without cushion member 72, and make it more attractive in appearance.
The 2nd scheme is in the 1st scheme, on the panel member 14 of that side that guides blowing directions by air ducting 18, from the end edge portion of blowing mouth 16 periphery to aircondition body 10, the outer inclination face 14a that formation is tilted to the direction near ceiling, this outer inclination face 14a are more than 10 degree at the inclination angle of the relative ceiling in aforementioned blowing mouth 16 end edge portion vicinity at least.And this inclination angle is preferably 10.8 degree (the 8th scheme).
This scheme weakens the wall attachment effect between the outer inclination face 14a that air-conditioning air-flow that blowing mouth 16 blows out and blowing mouth form member, can improve the action effect of aforementioned the 1st scheme.
The 3rd scheme is in the 1st scheme, and the boundary position of aircondition body 10 and ceiling 70 is more than 10 degree with the angle of inclination of the relative ceiling 70 of line of the foot of the panel member 14 of that side that is guided blowing directions by air ducting 18.This inclination angle is preferably 10.8 degree (the 10th scheme).
This scheme weakens the wall attachment effect between the surface that air-conditioning air-flow that blowing mouth 16 blows out and blowing mouth form member, can obtain and the identical action effect of aforementioned the 3rd scheme.
The 4th scheme is in aforementioned the 1st scheme, formation is from by the foot of the panel member 14 of that side of the air ducting 18 guiding blowing directions periphery to aircondition body 10, formation to the 1st inclined plane 14a that tilts near the direction of ceiling and with the 2nd continuous inclined plane of this inclined plane 14a, simultaneously, the inclination angle of the relative ceiling 70 of aforementioned the 1st inclined plane 14a is below 12 degree, and the inclination angle of the relative ceiling 70 in the 2nd inclined plane surpasses 12 degree.
This scheme makes the part of the Air Conditioning that blows out from blowing mouth 16 flow along the 1st inclined plane 14a, peels off in the position, boundary on the 1st inclined plane 14a and the 2nd inclined plane then, can improve the action effect of aforementioned the 1st scheme like this.
The 7th scheme is in aforementioned the 4th scheme, gets more than the 70mm from foot to the 1 inclined plane 14A of panel member 14 and the distance of position, boundary, the 2nd inclined plane.

Example 1
Fig. 1 is the longitudinal section of an example structure of expression ceiling built-in air-conditioning system 1 of the present invention.As shown in the drawing, in the housing 10 of this aircondition 1 (aircondition body) fan 20 and heat exchanger 30 are housed, aircondition 1 is embedded in being provided with in the opening 71 of ceiling 70 openings, is installed on the space at the ceiling back side.
Aforementioned housing 10 is made up of with the decoration panel 14 of the bottom surface peristome that covers this body housing 11 the container-like body housing 11 towards the below opening, is fixed in the Liang Dengshang of top by not shown suspender hanging.Specifically, aforementioned body housing 11 is made up of the side plate 13 that is octagonal top board 12 after foursquare four jiaos are cut away and extend towards the below from the outer edge of this top board 12, and aforementioned decoration panel 14 is for approximate foursquare tabular, be installed on the bottom of aforementioned side plate 13, simultaneously its outer peripheral edges portion by after the cushion member 72 chatted be fixed in ceiling 70.
As shown in Figure 2, the air suction inlet 15 in that the substantial middle portion of aforementioned decorative panel 14 forms square openings forms 4 elongated rectangle blowing mouths 16 along four limits simultaneously in the outside, four limits of this air suction inlet 15.In aforementioned air suction inlet 15, be provided with air cleaner 17 all sidedly to remove the floating materials such as microgranular dust that contain in the room air, the whole downside of air cleaner 17 is supported by cancellate strainer cover simultaneously, is provided with the horizontal blade 18 that the blow-off direction of Air Conditioning can be changed up and down at aforementioned blowing mouth 16.Utilize the opening decoration panel 14 that has blowing mouth 16 like this to constitute blowing mouth shown in Figure 3 and form member.
Specifically as shown in Figures 3 and 4, the vertical plane 16a that extends downwards by near normal ground of the sidewall of the panel outer circumferential side (right side among the figure) of the air duct that is communicated with the blowing mouth 16 of decoration panel 14 and from the lower end of this vertical plane 16a inclined plane 16b downward-sloping and that link to each other with the downside of decoration panel 14 forms towards the panel outer circumferential side.And the side plate of all sides (left side among the figure) is formed by reach the vertical plane 16d that down extends from the near normal ground, lower end of this flexure plane 16c towards the downward flexure plane 16c that protrudes of panel outer circumferential side in the panel of the air duct that is communicated with aforementioned blowing mouth 16.Form opposed facing 2 walls of shape like this at the whole length direction (direction vertical with paper) of blowing mouth 16, the air duct that is sandwiched between two walls has the function of extension line, can change the rectification limit, air-conditioning air-flow limit towards blowing mouth 16 to flow to.Extension line to the Air Conditioning run-up distance of blowing mouth 16 is about more than the 30mm.
Aforementioned levels blade 18 is a rectangular board member shown in Figure 5, slightly crooked along its width, after being installed on the blowing mouth 16, bolster X around the cardinal extremity side edge part that is contained in these blowing mouth 16 inboards (upstream side of air-conditioning air-flow) rotates freely, and it is that center of rotation is rotated with bolster X by not shown motor-driven.When Air Conditioning is blown out below, as shown in Figure 4, the back side 18b of horizontal blade 18 overlaps shape ground down with the vertical plane 16d of the interior all sides of aforementioned panel, and when so-called level is dried state, as shown in Figure 3, the rake 16b almost parallel ground of the front 18b of horizontal blade 18 and aforementioned panel outer circumferential side wall up.
Aforementioned fan 20 is arranged on the substantial middle position of body housing 11 inside, is the so-called turbine type fan that blade 23 is housed at guard shield 21,22 of wheel hubs.The driving shaft 26 that is installed in the fan electromotor 25 on the top board 12 of body housing 11 inserts in the wheel hub 22 of these fans 20 fixing, makes fan 20 rotations by the driving force of this fan electromotor 25, thereby will send to side radially from fan 20 below inhaled airs.Below fan 20, be provided with the horn mouth 27 of the air in air suction inlet 15 inflow housings 10 being guided into fan 20 in addition.
Aforesaid heat exchangers 30 is made up of a plurality of plate-shaped fins 31 that are provided with parallel to each other and the heat-transfer pipe 32 that runs through these fins 31, is so-called intersection finned type heat exchanger.When this heat exchanger 30 is overlooked rectangular tubular be trapped among aforementioned fan 20 around, be connected with off-premises station by not shown refrigerant piping, as evaporimeter, play a role as condenser when system warms up operation during refrigerating operaton, be used to regulate the air themperature of sending from fan 20.Below this heat exchanger 30, be provided with the drip tray 33 of accepting condensed water.
That is, in the housing 11 of aircondition 1, form from the air suction inlet 15 of decoration panel 14 through air cleaner 17, horn mouth 27, fan 20, and heat exchanger 30 arrive the gas channel W of blowing mouths 16.In case fan 20 startings during operation of air conditioner, the room air that enters housing 10 by air cleaner 17 from air suction inlet 15 promptly honks mouthfuls 27, the sequential flow of fan 20 and heat exchanger 30 is crossed gas channel W, carry out heat exchange in heat exchanger 30 and between the cold-producing medium with after regulating temperature (heating when cooling during refrigerating operaton, the warm operation of system), blow to the interior space as Air Conditioning by blowing mouth 16, to regulate the air of this interior space.
The principal character of this example 1 is to be provided with to regulate both above-below directions cushion member 72 at interval between the decoration panel 14 of aircondition 1 and ceiling 70, thus as shown in Figure 3, will be by the rising wood of the blowing mouth on the decoration panel 14 16, promptly foot and the interval of the above-below direction between the ceiling 70 h that forms member by the blowing mouth of horizontal blade 18 guiding Air Conditioning blow-off directions is set at (preferably 45mm) more than the 45mm, simultaneously the interval L between the outer peripheral edges portion (boundary position of decoration panel 14 and ceiling 70) of the rising wood and the decoration panel 14 of this blowing mouth 16 is set in more than the 90mm.
In other words, in this example, the air-flow that blows out from aforementioned blowing mouth 16 finally is positioned at more than the ceiling 70 below 45mm from the position that decoration panel 14 is peeled off, and the distance L between the boundary position of this position and decoration panel 14 and ceiling 70 is more than the 90mm, like this, can prevent that the Air Conditioning that blows out from blowing mouth 16 with so-called level blowing state from flowing along the downside of ceiling 70 during refrigerating operaton.Promptly, when at first requiring Air Conditioning to blow out down when the warm operation of system etc., shown in Figure 4 as described above, make horizontal blade 18 near vertically downward, make Air Conditioning and shown in arrow S among the figure, downwards near vertically blowing out along the vertical plane 16a of the panel outer circumferential side of this horizontal blade 18 and blowing mouth 16.
And when refrigerating operaton etc. during so-called level blowing state, shown in Figure 3 as described above, horizontal blade 18 is upwards rotated, make the inclined plane 16b almost parallel of the panel outer circumferential side sidewall of the leading flank 18a of this horizontal blade 18 and blowing mouth 16.Like this, Air Conditioning is just along the sidewall of the air duct (extension line) that is communicated with blowing mouth 16 and 18 leading flank 18a flows agley from flexure plane 16c along horizontal blade, very big and mild variation takes place in its grain direction, shown in arrow S among the figure, between the inclined plane 16b and horizontal blade 18 of the panel outer circumferential side by blowing mouth 16, from blowing mouth 16 with near the angle parallel with ceiling 70 (such as and ceiling 70 downsides between angle be about 30 °~35 °) blow out.
At this moment, when the Air Conditioning that blows to the interior space from blowing mouth 16 becomes jet flow, it blows out angle when parallel with ceiling 70, the jet flow axle is crooked up because of wall attachment effect, but in this example, because aforementioned blowing mouth 16 is arranged on and suitably leaves ceiling 70 places, so as long as near the air-flow these blowing mouth 16 central portions blow out initial velocity for the time such as the general value of about 2~6m/ second, the air-flow that comprises the two side portions that blows out the less relatively blowing mouth of initial velocity 16, the air-flow of Air Conditioning can not rise to the downside of ceiling 70, finally descends mobile because of the temperature difference with room air.
Promptly, past is in the lower part of the cold air blast velocity of ceiling built-in air-conditioning system, because of wall attachment effect makes air-flow easily near ceiling 70 downsides, the blow-off direction that makes Air Conditioning with horizontal blade 18 during refrigerating operaton relatively up, with ceiling 70 downsides such as being about 40~45 °, so, air-flow will flow along ceiling 70 downsides, and in the dirt of zone shown in dotted lines in Figure 2 (D) generation ceiling, but adopt the aircondition 1 of this example, suitable configuration structure by blowing mouth 16, even utilize horizontal blade 18 to make the Air Conditioning blow-off direction of this blowing mouth 16 and ceiling 70 downsides such as being close to about 30~35 °, this air-flow also flows along ceiling 70 downsides hardly, so just can solve the traditional subject of ceiling dirt.

The minimum that the ceiling dirt does not take place blows out angle 44° 40° 41° 42° 34° 32° 36° 36°
Table 1 is at the different 4 kinds of airconditions (Class1~4) of blowing mouth size shape, with the configuration of as this example, regulating blowing mouth 16 separately by cushion member 72, the occasion that is installed in then on the ceiling 70 contrasts with the occasion of not using this cushion member 72 to be directly installed on the ceiling 70, and actual motion after the stipulated time the dirty situation to ceiling carry out the result that inquiry agency gets, according to this experimental result, can find, no matter the size shape of blowing mouth 16 how, utilize cushion member 72 just can make the minimum that the ceiling dirt can not take place blow out angle and reduce 5~10 °.
Therefore, the aircondition 1 of this example makes blowing mouth 16 suitably leave ceiling 70 by cushion member 72 is set between decoration panel 14 and ceiling 70, so especially, when the refrigerating operaton that requires the Air Conditioning level to blow out, both can prevent the ceiling dirt, the blow-off direction that can make Air Conditioning again more near horizontal direction, has not only been guaranteed air-conditioner efficiency but also eliminated indoor inhabitation personnel's sticky feeling than traditional.
In addition, under the lower situation of the requirement that prevents the ceiling dirt, also can not use cushion member 72 that aircondition 1 is set, can increase the associative perception of aircondition 1 and ceiling like this, make appearance looks elegant.
Variation
Fig. 6 is the variation of aforementioned example 1, and this variation is being provided with the protruding plate 16e that extends below tiltedly from the rising wood of blowing mouth 16 on the decoration panel 14.At this moment, the foot that guides the blowing mouth of Air Conditioning blow-off directions to form member by horizontal blade 18 no longer is the rising wood of blowing mouth 16, but the leading section of aforementioned protruding plate 16e.Therefore, as long as the distance h from this protruding plate 16e leading section position to ceiling 70 is set at more than the 45mm, simultaneously this leading section position is set at more than the 90mm to decoration panel 14 distance L with the boundary position of ceiling 70, just can obtains the action effect identical with aforementioned example 1.
Example 2
Fig. 7 is the example 2 of ceiling built-in air-conditioning system 1 of the present invention, the aircondition 1 of this example 2 is except the detailed structure of blowing mouth 16 grades, other is identical with aforementioned example 1, below same member is used prosign, and detailed.The principal character of this example 2 is identical with aforementioned example 1, promptly between the decoration panel 14 of aircondition 1 and ceiling 70, cushion member 72 is set, the rising wood of blowing mouth 16 is arranged in suitably leaves ceiling 70 downside places, even and upwards flow and have the part air-flow upwards to flow, also can not make the dirty size shape of setting the decoration panel 14 in blowing mouth 16 outsides of ceiling 70 downsides for the air-flow that blowing mouth 16 is blown out because of the sharp dust that wherein contains.
Specifically, blowing mouth 16 outsides on decoration panel 14, promptly be provided with the outer circumferential side from the rising wood of blowing mouth 16 towards air conditioner case 10 by that sides of horizontal blade 18 guiding Air Conditioning blow-off directions and the outer inclination face 14a of the almost plane shape that tilts to the direction near ceiling 70 downsides, the tiltangle of the relative ceiling of this outer inclination face 14a is (with 10.8 degree for good) more than 10 °.Like this air-flow (jet flow) that blows out from blowing mouth 16 during refrigerating operaton etc. at first owing to and the outer inclination face 14a of decoration panel 14 between wall attachment effect be bent upwards, but can relax wall attachment effect by the heeling condition of setting this outer inclination face 14a, weaken Air Conditioning air-flow up.
In addition, h is identical with aforementioned example 1 at interval for above-below direction between aforementioned blowing mouth 16 rising woods and ceiling 70 downsides, be set at more than the 45mm, and the peripheral end that these blowing mouth 16 rising woods leave cushion member 72 in the horizontal direction is quite far away, in other words, the horizontal direction distance A between the boundary position of blowing mouth 16 rising woods and aircondition 1 and ceiling 70 is set in 75mm above (is good with 79mm).Like this, even the part of the Air Conditioning that blows out from blowing mouth 16 flows up, outer inclination face 14a along decoration panel 14 flows then, also leave in the horizontal direction because of the rising wood of blowing mouth 16 and the boundary position of 70 on ceiling quite far away, make along decoration panel 14 airflow flowing major parts before arriving ceiling 70, just to descend.
In this example 2, such as having a cowling panel 19,19 with shown in Figure 8 ... horizontal blade 18 replace the horizontal blade 18 of aforementioned example 1.This horizontal blade 18 is by forming at the curvulate rectangular board member of width, and its crooked medial surface 18a is a leading flank, and lateral surface 18b is the back side.At the length direction both ends of horizontal blade 18 integrally formed conchoidal lug boss 18c, 18c towards the front face side projection are arranged respectively, each self-forming is along the outward extending connecting pin 18d of the length direction of horizontal blade 18,18d on this each lug boss 18c end.Aforementioned levels blade 18 as described above Fig. 7 be located at like that under the state of blowing mouth 16, (upstream side that Air Conditioning flows: aforementioned 2 connecting pin 18d, the 18d left side of figure) are rotated by the connecting elements 14b on the decoration panel 14 and connect supporting freely to be positioned at blowing mouth 16 inboards, like this, horizontal blade 18 is that pivot rotates up and down with bolster X promptly under not shown motor-driven.
In addition, on the inwards crooked leading flank 18a of aforementioned levels blade 18, horizontal blade 18 whole length directions in accordance with regulations the fixed interval configuration be used for a plurality of cowling panels 19,19 that the rectification Air Conditioning flows ...Each cowling panel 19 vertically intersects in the width configuration of whole horizontal blade 18 and with the leading flank 18a of horizontal blade 18 is approaching, shown in arrow S among the figure, the Air Conditioning that flows along the leading flank 18a of horizontal blade 18 obtains rectification at the whole length direction of horizontal blade 18 when flowing through between each cowling panel 19.Like this by cowling panel 19,19 ... air-flow after the rectification becomes basic two-dimentional air-flow along vertical plane, so the initial velocity of the Air Conditioning that blowing mouth 16 blows out is also fast equally with middle body in the two side portions of blowing mouth 16.
Therefore, the aircondition 1 of this example 2 uses the cushion member 72 identical with aforementioned example 1, the rising wood of blowing mouth 16 is arranged in the position of suitably leaving ceiling 70 downsides along the vertical direction, and these blowing mouth 16 rising woods are arranged in that along continuous straight runs leaves and the boundary position position enough far away of 70 on ceiling, and make the relative level of outer inclination face 14a of the decoration panel 14 that links to each other with blowing mouth 16 rising woods that bigger inclination arranged, therefore the level in Air Conditioning blows out under the state, it is crooked up at first can to suppress the air-flow that blows out from blowing mouth 16, and then a part of air-flow that flows up along decoration panel 14 was descended before arriving ceiling 70 downsides, so comparable example 1 more effectively prevents the dirt to ceiling of the dust that contains in the air.
In addition, cowling panel 19,19 is set on horizontal blade 18 in this example 2 ... come the air-flow of Air Conditioning is carried out rectification, descend so almost can eliminate the air velocity that blows out of blowing mouth 16 two side portions, and it is upwards mobile to suppress air-flow in this part, can further improve aforementioned action effect.
Other example
The present invention is not limited to aforementioned example 1 and 2, also comprises other various examples.Promptly, in aforementioned each example, be between decoration panel 14 and ceiling 70, the position that cushion member 72 is regulated blowing mouth 16 to be set, but also can strengthen the above-below direction size of decoration panel 14 in advance, not use cushion member 72 and blowing mouth 16 is arranged in the position of suitably leaving ceiling 70 downsides.
In addition, all horizontal blade 18 is set in aforementioned each example, changing flowing of Air Conditioning up and down, but also can establish horizontal blade 18, only utilize to the curved shape guiding Air Conditioning of the air duct of blowing mouth 16 and flow at blowing mouth 16.At this moment, air duct itself becomes guiding device.
In the aircondition 1 of aforementioned example 1, h sets especially to the interval of the above-below direction between blowing mouth 16 rising woods and ceiling 70 downsides, in addition, in the aircondition 1 of example 2, also to blowing mouth 16 rising woods till the boundary position of 70 on air conditioner case 10 and ceiling horizontal range A and the tilt angle theta of decoration panel outer inclination face 14a done special setting, but be not limited thereto, that is, such as needing only a generation that can similarly alleviate the ceiling dirt greatly of setting in aforementioned levels distance A or the tilt angle theta with aforementioned each example.Perhaps arbitrary group in above-below direction interval h and horizontal range A, above-below direction interval h and tilt angle theta or horizontal range A and the tilt angle theta is set especially, just can be the same with aforementioned each example, can prevent the generation of ceiling dirt basically fully.
In the aircondition 1 of aforementioned example 2, the angle of inclination of relative ceiling 70 downsides of outer inclination face 14a is below 12 degree, this outer inclination face 14a that ins succession simultaneously forms the inclined plane, and the angle of inclination of relative ceiling 70 downsides in the 2nd inclined plane can surpass 12 degree.Like this, the part of the Air Conditioning that blows out from blowing mouth 16 just flows and is peeling off with the position, boundary on the 2nd inclined plane along said external inclined plane 14a, so also can alleviate the dirt of ceiling greatly.
