The specific embodiment
Below, with reference to the description of drawings embodiments of the present invention.
Fig. 1～Fig. 3 represents according to the embodiment of the present invention the indoor unit of 1 air conditioner, and Fig. 1 is that front view, Fig. 2 and Fig. 3 of indoor unit is respectively the profile along line I-I among Fig. 1 and line II-II.
As Fig. 1～shown in Figure 3, inside in indoor unit main body 11, accommodate heat exchanger 10, be used for drawing room air by heat exchanger 10, to the indoor filter for installation 1 that is blown into fan 14, is located at the upstream side of heat exchanger 10 through the air of over-heat-exchanger 10 heat exchanges, by fans in operation 14, suck air from a plurality of fronts across the suction inlet that forms (not shown) toply by main body 11, by be located at suction inlet and heat exchanger 10 between filter for installation 1, remove and to swim in airborne dust.
As shown in Figure 4, filter for installation 1 possesses: filter frame 2; Be installed in the air cleaner 5 on the filter frame 2; Along the face of the upstream side of air cleaner 5 in left and right directions (horizontal direction: arrow A) slide freely suction nozzle 4; Suction line 3 is installed in the main body 11 of a side (in the present embodiment for downside) of filter frame 2, guarantees to connect sliding freely hermetically an end of suction nozzle 4 simultaneously; Attract exhaust apparatus 6, be connected on the suction line 3, together attract, discharge dust with air; Blast pipe 7, one ends are connected and attract on the exhaust apparatus 6, and the other end is to outdoor opening.
As shown in Figure 5, suction nozzle 4 is pars intermedia bendings, lengthways forms, and prolongs to vertical direction, and the suction inlet 4a of the wide seam shape of 2～3mm is set in a side relative with air cleaner 5.In addition, in the inside of suction nozzle 4, form a plurality of (for example, 6) suction ventilation road to the inside of vertical separation suction nozzle 4.
The driving means that suction nozzle 4 is horizontally slipped is made of with silk 8 and the drive motors 9 that drives with threads 8 driving of suction line 3 sides that are attached at suction nozzle 4.
In addition, air cleaner 5 shown in Figure 4, loading and unloading are installed on the filter frame 2 freely, and filter frame 2 can be the part of main body 11, also can be on main body 11 fixed air filter 5, the formation that formation can not be loaded and unloaded.
Below, the work of the filter for installation 1 of above-mentioned formation is described.
If after air conditioner shuts down, attract exhaust apparatus 6 entrys into service, just the suction inlet 4a from the suction nozzle 4 that is communicated with suction line 3 begins to suck air.Then, be configured in a distolateral suction nozzle 4 of air cleaner 5, by the driving that links with drive motors 9 with silk 8, distolateral towards another of air cleaner 5, direction to arrow A is slided, and draws the lip-deep dust attached to air cleaner 5 simultaneously, is discharged to outdoor from blast pipe 7.The surface of suction nozzle 4 comprehensive cleaning air filters 5 arrives another of air cleaner 5 when distolateral, if reverse drive motors 9, suction nozzle 4 just moves to the direction that turns back to primary position, once more the surface of cleaning air filter 5.
Herein, by suction nozzle 4 inhaled airs, because by being located at a plurality of suction ventilations road 4b of its inside, so the attraction of suction nozzle 4 is reinforced, and dust collection efficiency improves.Promptly, do not have in the inside of suction nozzle 4 under the situation of a plurality of suction ventilations road 4b, the wind speed at suction inlet 4a place is then fast more (therefore near the connecting portion (bottom of suction nozzle 4) of suction nozzle 4 and suction line 3 more, air quantity is big), along with the connecting portion away from suction nozzle 4 and suction line 3, wind speed (attraction air capacity) reduces, but by the inside at suction nozzle 4 a plurality of ventilations road 4b is set, suction nozzle 4 can with the lengthwise position of suction inlet 4a irrespectively, approximate equality ground attracts air.
Fig. 6 A and Fig. 6 B represent to be located at according to the embodiment of the present invention the suction nozzle 4 on the indoor unit of 2 air conditioner, between the connecting portion of the suction inlet 4a of suction nozzle 4 and suction line 3, be provided with to the next door of extend longitudinally 4c, on the next door 4c, it is little near the connecting portion of suction line 3 that A/F is set, along with become big openings 4d gradually away from connecting portion.
Because other formation is identical with embodiment 1, so omit explanation.
In the present embodiment, from suction nozzle 4 suction air the time, since form on the next door 4c suction nozzle 4 in A/F towards above the openings 4d of increase gradually, so wind speed at suction inlet 4a place, no matter how from the distance of suction line 3, all roughly consistent, can draw surface dust on the whole expeditiously attached to air cleaner 5.Therefore, really can enough little attraction dust suctions, simultaneously, suction nozzle 4 compactnesses can be accommodated under the situation that does not reduce wind pushing performance in the space of qualification of indoor unit.
Fig. 7 A represents the variation of suction nozzle 4, by a plurality of (for example, 2) isolation part 4e, the openings 4d shown in Fig. 6 B is divided into a plurality of (for example, 3) openings 4d1.
Fig. 7 B represents another variation of suction nozzle 4, and along with the connecting portion away from suction nozzle 4 and suction line 3, stage ground increases the width of openings 4d2.
In addition, Fig. 7 C represents the another variation of suction nozzle 4, and along with the connecting portion away from suction nozzle 4 and suction line 3, stage ground increases the width of openings 4d3, in the different part of width isolation part 4e is set simultaneously.
In addition, Fig. 7 D represents the another variation of suction nozzle 4, replaces the rectangle openings 4d3 shown in Fig. 7 C, adopts oval-shaped openings 4d4, and the connecting portion along with away from suction nozzle 4 and suction line 3 increases its area.
In addition, in the example of Fig. 7 A, Fig. 7 C or Fig. 7 D, next door 4c goes up and forms a plurality of openings 4d1 (4d3 or 4d4), along with the connecting portion away from suction nozzle 4 and suction line 3, increases the area of suction nozzle.
In addition, also can adopt Fig. 6 B or Fig. 7 A～Fig. 7 D openings in addition, as long as A/F or aperture area are near connecting portion little of suction nozzle 4 and suction line 3, which kind of shape no matter the shape along with increasing away from connecting portion adopt to play identical effect.
Fig. 8 represents to be located at according to the embodiment of the present invention the filter for installation 1 on the indoor unit of 3 air conditioner, this filter for installation 1, replace being located at the suction line 3 on the filter for installation 1 of described embodiment 1 or 2,, connect suction nozzle 4 and attract exhaust apparatus 6 by bending suction line 15 freely.
In the filter for installation 1 of above-mentioned formation, if attract exhaust apparatus 6 entrys into service, be positioned at a distolateral suction nozzle 4 of air cleaner 5, just by sliding to the direction of arrow A with silk 8 with the driving of drive motors 9 bindings, but owing to crooked constitute the suction line 15 that links suction nozzle 4 and attract exhaust apparatus 6 freely, so along with the slip of suction nozzle 4, suction line 15 bendings, suction nozzle 4 and its location independent are communicated with attracting exhaust apparatus 6 always.
In addition, the length of suction line 15 suction nozzle 4 being configured in another of air cleaner 5 when distolateral, is set in the mode that can how much have the crooked suction line 15 in fit tolerance ground.
Except that the suction nozzle 4 of above explanation, because other formation is identical with above-mentioned embodiment 1 or 2, so its explanation is omitted.
Fig. 9 is the profile (being seen the profile of suction nozzle by air cleaner 5 sides) of internal structure of the suction nozzle 4 of expression present embodiment.Suction line 15 is attached at the bottom of suction nozzle 4.In addition, actual suction nozzle 4, as shown in Figure 8, along air cleaner 5 bendings, but in Fig. 9, for ease of with the aid of pictures, to extend the state diagram of suction nozzle 4 as the crow flies.
As shown in Figure 9, the inside of suction nozzle 4 from being used to attract the suction inlet 4a attached to the seam shape of the dust on the air cleaner 5, is separated into a plurality of ventilations road by a plurality of flow distribution plates 22, and links with suction line 15.In the present embodiment, be separated into 4 ventilation roads, begun by the ventilation road near suction line 15, be defined as ventilation road A, B, C, D successively, the wind speed separate provision of the suction inlet 4a that each road that ventilates attracts is wind speed V
A, V
B, V
C, V
DBecause the attraction cleaning performance of air cleaner 5 depends on this wind speed to a great extent, so must make wind speed V
A～V
DHomogenising is guaranteed enough wind speed simultaneously.In addition, the duct width with each ventilation road is defined as ta, tb, tc, td.In the drawings, hollow arrow is represented flowing of wind.
In the suction nozzle of no flow distribution plate 22, because near the resistance of the ventilation road A of suction line 15 resistance, so the mobile ventilation road A that concentrates on of wind less than the ventilation road of other B, C, D.Its result, wind speed V
AThe highest, along with the front end near suction nozzle 4, wind speed is pressed V
B, V
C, V
DOrder reduce.As mentioned above, because the attraction cleaning performance of air cleaner 5 depends on this wind speed to a great extent, so more near the front end of suction nozzle 4, the cleaning ability is low more.Therefore,,, also have to improve the output that attracts exhaust apparatus 6, need powerful attraction exhaust apparatus even be to have reached required above wind speed for ventilation road A for the ventilation road D of suction nozzle 4 leading sections has enough attractions.Therefore, in the present embodiment,, make the resistance homogenising of ventilation road A～D, make wind speed V by flow distribution plate 22 is set
A～V
DHomogenising.Its result promptly uses low power attraction exhaust apparatus 6, to the front end of suction nozzle 4, also can both bring into play sufficient attraction.
In addition, can utilize flow distribution plate 22 to make respectively to ventilate the suitable homogenising of road A～D, but however, because ventilation road length from the suction inlet 4a of each ventilation road A～D to suction line 15, the ventilation road A～D (promptly pressing the order of ventilation road A, B, C, D) that reaches suction nozzle 4 front ends more is long more, the flowing resistance that produces between ventilation road A～D is poor, so wind speed V
A～V
DNot exclusively evenly.
Therefore, in duct width ta, the tb of each ventilation road A～D, tc, td, increase the size of the duct width td of the big draft power D of flowing resistance the biglyyest, below by the order of tc, tb, the ta duct width that narrows down.Because the resistance of ventilation road A～D that duct width is big reduces, so, can make wind speed V more by so that the mode that flowing resistance equates is set the size of ta, tb, tc, td
A～V
DHomogenising is promptly used low power attraction exhaust apparatus 6, to the front end of suction nozzle 4, also can bring into play sufficient attraction.
Figure 10 represents the variation of suction nozzle 4, ventilation degree of having a lot of social connections by part in the way that enlarges the big ventilation road A～D of flowing resistance can reduce the flowing resistance of ventilation road integral body, and promptly use low power attraction exhaust apparatus 6, to the front end of suction nozzle 4, also can bring into play sufficient attraction.
Figure 11 represents another variation of suction nozzle 4, further the reduction flowing resistance among the A～D of road of respectively ventilating.
If be described in detail then as follows.By flow distribution plate 22 being set, the wind speed V of each road A～D that ventilates
A～V
DHomogenising roughly, but small poor of the wind speed among the road A～D that respectively ventilates (below, be called the wind speed ventilation road in) generation.For example, if be example, even in the D of ventilation road, near the wind speed V of the low suction line 15 of flowing resistance with the ventilation road D among Fig. 9
D1, greater than wind speed V near suction nozzle 4 front ends
D2To suppress as far as possible that so wind speed is poor, effective method is the opening length that shortens the attraction mouth 4a on each ventilation road, increase and divide fluxion, but in such cases, owing to also increase the quantity of flow distribution plate 22, ventilation road by its thickness of slab degree narrows down total can not increase flowing resistance on the contrary, so the branch fluxion is preferably set in the scope of allowing of wind speed difference in the ventilation road less as far as possible.
; because the wind speed difference has the more little tendency that worsens more of thickness on ventilation road in the ventilation road; so preferably set the thickness of suction nozzle 4 fully; but the aspects such as accommodating property in indoor unit are considered; when needing the thickness of part attenuate suction nozzle 4; flowing resistance on the ventilation road of the part of thickness thinning circulation increases the wind speed difference increase ventilation road in.Thereby, wind speed difference in the ventilation road of suction nozzle 4 is suppressed in the permissible range with the branch fluxion of minimum, about the big ventilation road of flowing resistance, i.e. the ventilation road of the part of the reduced thickness of suction nozzle 4 is preferably formed as the formation of the length that only shortens suction inlet 4a.
As shown in figure 11, be located at 300mm in length overall with suction nozzle 4, to be the boundary with the dotted line be set at suction nozzle 4 front under the situation of size that thickness t=8mm, suction line 15 sides be set in thickness t=12mm, preferably, the suction inlet 4a that is configured in the ventilation curb shunting on the part of thickness t=12mm is lengthened to long 90mm (the about 2mm of width), and the suction inlet 4a that is configured in the ventilation curb shunting on the part of thickness t=8mm shortens to long 60mm (the about 2mm of width).By formation like this, branch fluxion that can enough minimums makes the flowing resistance of suction nozzle 4 integral body reach minimum, and wind speed is poor in the ventilation road of the road A～D that suppresses simultaneously respectively to ventilate.
Figure 12 represents the another variation of suction nozzle 4, and the cowling panel that dwindles ventilation road A～D is set on each ventilation road A～D.
If be described in detail, according to above-mentioned formation, the wind speed homogenising of the road A～D that respectively ventilates of suction nozzle 4 can be made, but, required branch fluxion can not be guaranteed because of the restriction of the size that is subjected to suction nozzle 4, it is poor to occur in the big ventilation road wind speed sometimes.In such cases, as shown in figure 12, by the cowling panel 23 that dwindles ventilation road A～D is set on each ventilation road, wind speed is poor in the road that can suppress to ventilate.
As mentioned above, poor because of the flowing resistance among each ventilation road A～D, near the wind speed of suction line 15 greater than wind speed near suction nozzle 4 front ends.Therefore, by the cowling panel 23 that forms peristome 24 is set, make the flowing resistance homogenising in the ventilation road near the central portion of each ventilation road A～D, wind speed is poor in the improvement ventilation road.Certainly preferred, according to the shape on ventilation road, with the set positions of the position of cowling panel 23 or peristome 24 on the position of the best.According to so constituting, even by the branch fluxion that limits, wind speed is poor in the ventilation road of the road A～D that also can suppress respectively to ventilate.
Figure 13 represents to be located at according to the embodiment of the present invention the part of the filter for installation 1 on the indoor unit of 4 air conditioner, and the ventilation road opening and closing device of the ventilation road A～D that opens and closes suction nozzle shown in Figure 94 successively is set.
Ventilation road opening and closing device has: ventilation road switch boards 25, be located on the linking part of suction nozzle 4 and suction line 15, and be used for opening 1 of ventilation road A～D, close other ventilation roads among the A～D of ventilation road simultaneously; Be located at the driven gear 26 on the ventilation road switch boards 25; Driven wheel 27 with driven gear 26 engagements; Drive the driving means such as stepper motor 28 of driven wheel 27.Ventilation road switch boards 25 by driving means 28, is slided via driven wheel 27 and driven gear 26.
Figure 13 is the state of opening ventilation road A, closing other ventilation road B, C, D.If, ventilation road switch boards 25 is moved to the position of Figure 14 from the position of Figure 13 by driving means 28, just open ventilation road B, close other ventilation road A, C, D.Ventilation road C or ventilation road D too can be by utilizing driving means 28, slip ventilation road switch boards 25 and opening.
, attract the required power of exhaust apparatus 6 herein, be shown below, depend on air quantity.
W＝(qe×R)/(6.118×Φ×η)
W: attract power (W)
Qe: attract air quantity (m
3/ min)
R: flowing resistance (mmAq)
Φ: attract fan efficiency
η: attract electric efficiency
If the wind speed of each ventilation road A～D is set at v, the area of the suction inlet 4a of suction nozzle 2 is set at S, owing to represent air quantity with qe=v * S, so keep wind speed, reduce the power that attracts exhaust apparatus 6, effective method is that the area S (promptly dwindling suction inlet 4a) that reduces suction inlet 4a reduces air quantity.
In example shown in Figure 14, by suitable mobile ventilation road switch boards 25, open 4 ventilation road A～D successively, by only attracting air, can seek to reduce air quantity qe from 1 ventilation road, can attract 5 whole of cleaning air filters by enough few air quantity.
If be described more specifically with reference to Fig. 8, at first only open ventilation road A, by coming and going mobile suction nozzle 4, attract the P1 scope of cleaning air filter 5 along guide rail 16.Then,, only open ventilation road B by utilizing driving means 28 slip ventilation road switch boards 25, same by coming and going mobile suction nozzle 4, attract the P2 scope of cleaning air filter 5.By similarly cleaning ventilation road C, D successively, attract P3, the P4 scope of cleaning air filter 5, finish the attraction cleaning of 5 whole of air cleaners.In this process, because the total amount of air quantity qe is only supplied with 1 ventilation road, so attract that the required power of exhaust apparatus 6 is very little also can finish cleaning.
In indoor unit, inhomogeneous through the air-supply wind speed of air cleaner 5, the wind speed of front face side is fast, also increases attached to the amount of the dust on this part air cleaner 5.That is, in Fig. 8, attached to the P1 of air cleaner 5, the amount of dust in the P2 scope greater than P3, P4 scope.Thereby, in the present embodiment, during the big part of the dust adhesion amount on cleaning air filter 5, by improving the output that attracts exhaust apparatus 6, really can clean (owing to improve the output that attracts exhaust apparatus 6 with whole zone, therefore the electric power that not only increases consumption, and acceleration components consumption are not suitable for adopting).
Following table is represented the attraction output (attracting the fan rotation number) on each ventilation road and is attracted wind speed.Attraction speed by with the attraction cleaning of P1, the P2 of air cleaner 5 time, the attraction speed during with respect to the attraction cleaning of P3, P4 part is set in 1.2 times, can improve the cleaning ability when cleaning dust and adhering to part how.Even this function at suction nozzle 4, because of the structure of indoor unit etc., haves no alternative but form under the situation on the big ventilation road of flowing resistance, by rising attraction when attracting cleaning with this ventilation road only, also can use when obtaining enough attraction performances.
| The ventilation road of open mode | Ventilation road A | Ventilation road B | Ventilation road C | Ventilation road D |
| Attract output (attracting the fan rotation number) | 6000r/min | 6000r/min | 5000r/min | 5000r/min |
| Attract wind speed | 18m/sec | 18m/sec | 15m/sec | 15m/sec |
In addition, in the above-described embodiment, air cleaner 5 loading and unloading are installed on the filter frame 2 freely, but filter frame 2 also can be the part of main body 11, fixed air filter 5 on main body 11, the formation that formation can not be loaded and unloaded.But,, clean inexpungible dust, wet goods in the attraction cleaning works of suction nozzle 4 easily if air cleaner 5 loading and unloading are installed on the main body 11 freely.
In addition, in the above-described embodiment, after air conditioner shuts down, attract exhaust apparatus 6 entrys into service, but also can running attract exhaust apparatus 6 before air-conditioner operation or in the running.
In addition, in the above-described embodiment, attracting to connect blast pipe 7 on the exhaust apparatus 6, will together be discharged to outdoorly, but also not necessarily blast pipe 7 must be set by dust that attracts exhaust apparatus 6 to attract and air.In such cases, as long as attracting that the loading and unloading dust gathering arrester freely with dust-collecting net is set on the exhaust apparatus 6, capture by the dust that attracts exhaust apparatus 6 to attract with dust-collecting net, then by attracting the air that exhaust apparatus 6 is discharged and dust together attracts just passable, with the dust that dust-collecting net captures, can be by being removed from attracting exhaust apparatus 6 to take off dust gathering arrester.
