Followingly example of the present invention is elaborated with reference to accompanying drawing.
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.
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.
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 along the vertical plane 16a of the panel outer circumferential side of this horizontal blade 18 and blowing mouth 16 and shown in arrow S among the figure like that near vertically blowing out downwards.
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.
Table 1
| Traditional aircondition | Aircondition of the present invention | |||||||
| The blowing mouth type | 1 | 2 | 3 | 4 | 1 | 2 | 3 | 4 |
| The minimum that the ceiling dirt does not take place blows out | 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, be installed in occasion on the ceiling 70 then and be directly installed on occasion contrast on the ceiling 70 with not using this cushion member 72, 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 sense of discomfort 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 described example 1, in this variation, at blowing mouth 16 rising woods, promptly the protrusion board 16e that towards tiltedly below extend of guiding from the air-conditioning air-flow of this blowing mouth 16 is set at blowing mouth 16 end edge portions by horizontal blade 18 guiding Air Conditioning blow-off directions.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 protrusion board 16e.Therefore, as long as will protrude board 16e leading section position from this is set at more than the 45mm to the distance h of ceiling 70, 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.
