The specific embodiment
Below, describe with reference to accompanying drawing about embodiments of the present invention.
Fig. 1 represents the indoor assembly of air conditioner of the present invention, inside at indoor assembly body 2, contain heat exchanger 4, fan 6 and be configured in the filter for installation 8 of heat exchanger 4 upstream sides, fan 6 is used for being taken into room air and carrying out heat-exchanged air to indoor blowing out by heat exchanger 4 by heat exchanger 4, action by fan 6 sucks air from a plurality of suction inlets, suction inlet from the front of body 2 spread all over be formed on above, swim in airborne dust and remove by the filter for installation 8 that is arranged between suction inlet and the heat exchanger 4.
Embodiment 1
Fig. 2 is the whole pie graph of the filter for installation 8 of the air conditioner in the embodiments of the present invention 1.As shown in Figure 2, remove air cleaner, constitute, slip suction nozzle 14 freely is installed along the surface of air cleaner by filter frame 10, the filter webs 12 that remains on the filter frame 10 by the airborne dust of heat exchanger 4.Suction nozzle 14 utilizes the pair of guide rails 16 that is arranged on filter frame 10 upper and lower sides, can keep certain distance move left and right swimmingly with air cleaner.An end that links attraction pipeline 18 on the suction nozzle 14, the other end of attraction pipeline 18 and suction device 20 link.Attraction pipeline 18 is formed by bent pipeline, so that can not hinder moving of suction nozzle 14.Also have, link discharge duct 22 on the suction device 20, to outdoor draw around.Attract by suction nozzle 14 attached to the dust on the air cleaner, and via attraction pipeline 18, suction device 20, discharge duct 22 to outdoor discharge.
In general home-use small air-conditioning system, during built-in described filter for installation, need to realize the little outputization of miniaturization of suction device 20, thereby needing can be with the powerful attraction of little air quantity performance.At this, suction nozzle 14 is set at, and carries out throttling with the reinforcement attraction to attracting on a part, the attraction position of switched suction 14, and cleaning and filtering is whole thus.
Below, describe about attracting the position switching mechanism.
Shown in Fig. 3 A and Fig. 3 B, on suction nozzle body 24, be formed with the slot-shaped peristome 26 of the length suitable with the air cleaner total length, be with 28 to be provided with attraction hole 30 along what this peristome 26 can drive, thereby can a part attract, and can change the position of attraction by rotating band 28 from peristome 26.In addition, be with 28 need slide along suction nozzle body 24, thereby, be utilized integrally formed band guide groove 32 guiding of deposited or bonding etc. and suction nozzle body 24, and suppressed attracting the part beyond the hole to take place to attract to leak.According to this formation, even little air quantity also because throttling is little attraction hole, therefore attracts the wind speed in hole to increase, even small-sized suction device also can be brought into play powerful attraction.
Want the clean air filter whole, as shown in Figure 4, what make suction nozzle 14 is with 28 to slide up and down, change the position that attracts hole 30, and suction nozzle 14 horizontally slipped along filter webs 12, attract hole 30 shown in arrow among the figure, to scan (sweep) action like that thereby can make, clean whole.Among Fig. 4, attracting hole 30 be 1/4 length of air cleaner total length, moves whole of cleaning and filtering by 2 times shown in arrow among the figure round scanning.
But, consider from the noise of suction device 20 or the aspect of (axle wearing and tearing etc.) reliability or power supply capacity, will export the upper limit to set lowlyer, thereby, in order to ensure the attraction in when cleaning, need reduce the flowing resistance of suction nozzle 14 or pipeline (attraction pipeline 18 or discharge duct 22 etc.).Therefore, need the sectional area on the ventilation road of increase suction nozzle 14 or pipeline 18,22, slow down inner flow velocity, the dust of suction is deposited in the possibility of suction nozzle 14 or pipeline 18,22 inside when still having the attraction cleaning.If dust is suction nozzle 14 or pipeline 18,22 inner accumulations, then it not only becomes new flowing resistance and attraction is descended, and Once you begin piles up, and then the development of piling up along with dust causes the possibility that suction nozzle 14 or pipeline 18,22 all can be blocked.Therefore, the suction nozzle 14 of present embodiment though adopt the suction device 20 of little output, can be brought into play powerful attraction clean-up performance simultaneously and prevent suction nozzle 14 and the accumulation of the dust of pipeline 18,22 inside, below, describe about its details.
Get back to Fig. 3 A and Fig. 3 B, be formed with the assist openings portion 34 that attracts hole 30 half following length in peristome 26 both sides of suction nozzle body 24, also the same position on band guide groove 32 is formed with assist openings portion 36.The assist openings portion 36 of the assist openings portion 34 of suction nozzle 14 and band guide groove 32 in suction nozzle 14 set positions on vertically is, attracting hole 30 to be positioned at suction nozzle 14 foremost during the cleaning position of side, attract assist openings portion 34 lower ends (end in downstream) of 30 lower ends, hole (end in downstream) and suction nozzle 14 roughly consistent.
On the other hand, with the auxiliary attraction hole 38 that also is formed with on 28 with the assist openings portion 34 identical sizes of suction nozzle 14 in the both sides that attract hole 30.The auxiliary set positions in hole 38 that attracts is to attract 30 upper ends, hole (end of upstream side) roughly consistent with auxiliary 38 upper ends, hole (end of upstream side) that attract.Among Fig. 5 for the ease of understanding described formation, and to suction nozzle body 24 be with 28 to be described respectively.
Following explanation is carried out in action, effect about the filter for installation 8 of described formation.
Fig. 6 is with air cleaner and attracts the skeleton diagram of the suction nozzle 14 that the position (being cleaning position) in hole 30 compares, and is the figure (for the ease of understanding, economizing slightly guide groove 32) when the air cleaner side is seen suction nozzle 14.(a) is the situation of expression clean air filter P1 part among Fig. 6, and rotating band 28 is so that attract the position in hole 30 to come the position corresponding with air cleaner P1.At this state, the assist openings portion of suction nozzle 14 34 and stagger with the position in 28 auxiliary attraction hole 38, therefore, the part of opening (blacking part) just attracts hole 30.Thereby the wind that is attracted by suction device 20 only is attracted hole 30 throttlings, therefore, attracts the wind speed in the hole 30 to accelerate, and brings into play powerful attraction cleaning power.(b) is the situation of expression clean air filter P2 position among Fig. 6, and rotating band 28 is so that attract the position in hole 30 to come the position corresponding with air cleaner P2.At this state, the assist openings portion of suction nozzle 14 34 and also stagger with the position in 28 auxiliary attraction hole 38, therefore, the part of opening (blacking part) just attracts hole 30.Equally, in the situation of clean air filter P3 or P4 position, the part of opening just attracts hole 30.
And among Fig. 2, can be enough the air quantity that attracts of suction device 20 by total decision from the flowing resistance in each path of being attracted to discharge.The more little air quantity that then attracts of the total of flowing resistance is big more, can bring into play powerful attraction.Total in this flowing resistance can enough following formulas (1) expression.
Flowing resistance adds up to R=to attract hole flowing resistance r1+ suction nozzle flowing resistance r2+ attraction pipeline flowing resistance r3+ suction device flowing resistance r4+ discharge duct flowing resistance r5 ... (1)
By formula 1 as can be known, flowing resistance R be reduced, each flowing resistance of r1～r5 need be reduced respectively.Flowing resistance is ratio with 2 powers of wind speed in theory, therefore, chooses big ventilation road sectional area and reduces wind speed with respect to the air quantity that flows, thereby can make it to reduce.Specifically, by increasing the ventilation road sectional area of suction nozzle 14 inside among Fig. 2, can reduce r2, by increasing the ventilation road sectional area of attraction pipeline 18 inside, r3 can be reduced,, r4 can be reduced by increasing the ventilation road sectional area of suction device 20 inside, by increasing the ventilation road sectional area of discharge duct 22 inside, can reduce r5.As extreme example, inner wind speed is reduced to be tending towards 0 if choose very large ventilation road sectional area with respect to the air quantity that flows, then flowing resistance is tending towards 0.But,, can't carry dust (can't discharge), therefore must guarantee to carry the wind speed of dust because inner wind speed is 0.On the other hand, though attract hole flowing resistance r1 by the attraction hole wind speed decision that attracts in the hole 30, owing to attract the hole wind speed must guarantee to attract cleaning power, therefore, must guarantee setting above (for example, more than the 15m/s), thereby attraction hole flowing resistance r1 can not be too little.Thereby, need design to attract hole wind speed and each ventilation road sectional area to add up to reach the flowing resistance of guaranteeing the scope that attracts cleaning power and can carry dust.But, the output of suction device 20, consider from the reliability of noise, axle wearing and tearing etc. or the aspect of power supply capacity, the upper limit is very low (that is to say in output, can not improve the rotating speed that attracts fan), therefore, want to guarantee necessary attraction hole wind speed, if r2～r5 does not drop to the wind speed that can carry dust and can't set up with next sometimes.
Therefore, in the present embodiment, attract cleaning to carry out at Fig. 6 (a) or under the state (b), after attracting cleaning to finish, shown in (c), set, to enlarge the area that attracts, reduce wind speed (reducing to attract hole flowing resistance r1), increase from suction nozzle 14 and flow to air quantity the discharge duct 22.That is to say, when attracting cleaning, use whole power of suction device 20 (to enter the dust of suction nozzle 14 inside for dust being drawn into suction nozzle 14 inside because inner wind speed is low, therefore be deposited in suction nozzle 14 inside), thereafter, the area that increase to attract does not reduce attraction and air quantity is increased, bring up to the inside wind speed that to carry dust, dust one gas that is deposited in suction nozzle 14 inside is discharged.
Shown in Fig. 6 (c), in order to enlarge the area of attraction, and rotating band 28 makes and attracts hole 30 to come centre position between air cleaner P1 and the P2.At this state, the assist openings portion of suction nozzle 14 34 and with the position consistency in 28 auxiliary attraction hole 38, therefore, peristome (blacking part) becomes and attracts hole 30 and the auxiliary total that attracts hole 38, and aperture area is extended.Consequently, attract the hole wind speed decreased, attract hole resistance r1 also to reduce, therefore attract air quantity to increase.Thereby 22 inside flow velocity also increases from suction nozzle 14 to discharge duct, can promote to be deposited in that inner dust flows and with its discharge.Attracting the position in hole 30 is the centre position of P1 and P2, but owing to do not attract cleaning, does not therefore have problems.In addition, the assist openings portion 34 of suction nozzle 14 must discharge the dust that is deposited in suction nozzle 14 inside, and therefore, preferred disposition is (from the position that the linking part with attraction pipeline 18 leaves as far as possible) near the front end as far as possible of suction nozzle 14, also so sets in the present embodiment.
Also have, auxiliary attraction hole 38 with 28 is attracting 30 both sides, hole to be provided with 1 respectively, the assist openings portion 34 of suction nozzle 14 is provided with 1 respectively in the both sides of peristome 26 too, but, auxiliary hole 38 and the assist openings portion 34 of attracting also can only attract hole 30 and the one-sided of peristome 26 to be provided with 1 respectively.
But, as shown in Figure 7, if 2, the assist openings portion 34 of 4 suction nozzles 14 altogether are set respectively in peristome 26 both sides, and the auxiliary attraction hole 38 with 28 is set too, then enlarged openings area more obtains the effect bigger than the situation that is provided with 2.The assist openings portion 34 of suction nozzle 14 is 2 situation altogether in both sides, also will consider to increase the problem of its width, and the width of suction nozzle body 24 also has to increase at that time, causes taking in property poor.In addition, if suction nozzle 14 reaches in the stream of the wind by heat exchanger 4, the performance that then hindering ventilates makes air conditioner descends, and therefore, preferably links to each other like that as Fig. 7 (a)～(c) shown in and disposes.In addition, can also further increase the number of the assist openings portion 34 of suction nozzle 14.
Also have, among Fig. 6 or Fig. 7, with the assist openings portion 34 and peristome 26 independent settings of suction nozzle 14, this is based on following reason.When assist openings portion 34 and peristome 26 not separated settings, be with also to need on 28 to be provided with continuously to attract hole 30 and the auxiliary hole 38 that attracts, cause on 28 big attraction hole also is set.If rotating band 28 is used to change the position that attracts hole 30, then to being with 28 to apply tensile force, because big pore volume easily causes the fracture with 28, therefore, the assist openings portion 34 of preferred suction nozzle 14 and peristome 26 independent settings.
Also have, the expansion of aperture area is not limited to present embodiment, also the mechanical type open and close valve can be set, and in addition, assist openings portion 34 not only is arranged on the suction nozzle 14, also can be arranged in the way of attraction pipeline 18.
Fig. 8 represents the structure of suction device 20 set on the filter for installation 8 of the air conditioner in the present embodiment 2.The integral body of filter for installation 8 constitutes, and identical with embodiments of the present invention 1, therefore, it illustrates omission.
As shown in Figure 8, suction device body 40 is built-in with Sirocco fan 42, utilizes motor to make Sirocco fan 42 rotation at a high speed, thus the performance attraction.Attraction side at suction device body 40 links attraction pipeline 18, links discharge duct 22 at exhaust side.Have again, be formed with peristome 44, the opening-closing plate 48 that links with stepper motor 46 is installed freely in the one-sided swing of peristome 44 in the attraction side of suction device body 40.If utilize stepper motor 46 driven opening valves 48, then peristome 44 opens and closes.Surface in peristome 44 sides of opening-closing plate 44 is pasted with seal 50, if peristome 44 is by opening-closing plate 48 sealings, then opening-closing plate 48 connects airtight with the periphery of peristome 44.
With reference to Fig. 2 and Fig. 8 following explanation is carried out in action, the effect of the filter for installation that as above constitutes.
Can be enough the air quantity that attracts of suction device 20 by total decision from the flowing resistance in each path of being attracted to discharge, thereby as described in explanation in the enforcement mode 1, the more little attraction air quantity of the total of flowing resistance is big more.Consider from this viewpoint, reduce the flowing resistance r5 of discharge duct 22 more, promptly increase the ventilation road sectional area of discharge duct 22 more, the attraction when attracting cleaning is improved.At this moment, as implement as described in the mode 1, after attracting to clean, the dust that promotion is deposited in suction nozzle 14 and attraction pipeline 18 inside flows to suction device 20 and discharge duct 22, if increase the ventilation road sectional area of discharge duct 22, then dust might be deposited in the discharge duct 22 once more.In addition, dust also takes place to the accumulation of the housing of suction device body 40 or adhering to blade (pen feather) of Sirocco fan 42.
Therefore, peristome 44 and opening-closing plate 48 are set on suction device 20, if open peristome 44, then the wind of Xi Yining almost all is attracted into from peristome 44.The area of peristome 44 can more much bigger than the aperture area after the expansion of suction nozzle 14 of explanation in the embodiment 1 (because suction device 20 be bigger than suction nozzle 14), and therefore, the wind speed of the wind that is attracted by peristome 44 is slow, and the flowing resistance r4 of suction device 20 is very low.Have, wind does not flow in suction nozzle 14 and attraction pipeline 18 again, and therefore, attracting hole flowing resistance r1, suction nozzle flowing resistance r2 and attraction pipeline flowing resistance r3 is 0.Thereby the total R of flowing resistance only becomes the value near the flowing resistance r5 of discharge duct 22, can be very low.Consequently, even the rotating speed of Sirocco fan 42 is identical with the situation of embodiment 1, also can increase in suction device 20 and discharge duct 22 air quantity that flows significantly, the dust that can promote to be deposited in discharge duct 22 and suction device 20 inside flows and makes it to outdoor discharge.At this moment, can blow the dust that flies attached on Sirocco fan 42 blades, thereby Sirocco fan 42 can not stopped up yet by dust yet.The air quantity of this moment also reaches the air quantity of this degree of can taking a breath in normal room, therefore, when driven opening plate 48 is opened peristome 44, can adopt suction device 20 as scavenger fan, close peristome 44 when attracting to clean, can adopt suction device 20 as the attraction fan that attracts dust from the attraction hole 30 of suction nozzle 14.That is to say, can realize attracting cleaning function and ventilatory by enough same suction devices 20.
In addition, consider that also thereby periphery at peristome 44 adheres to some dust and can not close fully, cause attracting to leak, cause the situation that attracts clean-up performance to descend, therefore, can soft distortion and the seal 50 of permanent deformation seldom in opening-closing plate 48 surperficial attachings, prevent to attract to leak.As seal 50, can adopt soft expanded material such as EPT (ethylene propylene rubber), but also can adopt the gel rubber material etc. that compression is had very strong patience.
Fig. 8 and Fig. 9 represent the open mode and the closed condition of peristome 44 respectively, and the white arrow among Fig. 8 is represented the wind that attracted.White arrow among Fig. 9 is represented the wind that attracted too.
Also have, the fan that adopts in suction device 20 can also adopt turbofan etc. except Sirocco fan, but, when needing ventilatory, preferably adopt the big Sirocco fan of air quantity.When not needing ventilatory, turbofan also can obtain powerful attraction sometimes.

Following explanation is carried out in action, effect to the filter for installation of described formation.
At first, with reference to Fig. 2 and Figure 12 a succession of action that air cleaner cleans is described, filter for installation 8 is divided into 16 cleaning areas, utilize and back and forth scan for 8 times after action attracts cleaning, as the phase I of dust discharging operation, carry out the expansion action of the aperture area of the suction nozzle 14 of explanation in the embodiment 1.Next, as the second stage of dust discharging operation, carry out the opening action of the peristome 44 of the suction device 20 of explanation in the embodiment 2.Thereby, when making the attraction air quantity than the attraction cleaning, increases the phase I, the dust that promotion is deposited in suction nozzle 14 and attraction pipeline 18 inside flows to suction device 20, increases the attraction air quantity more in second stage, promotes to be deposited in dust in suction device 20 and the discharge duct 22 and flows and make its discharge.
Describe above action in detail with table shown in Figure 12.The rotating speed of the Sirocco fan 42 of suction device 20 considers that from the relation of noise etc. the upper limit is set at 6500r/min, all adopts these maximum (top) speeds in a succession of action.
When attracting cleaning, peristome is the attraction hole 30 of suction nozzle 14, and the attraction air quantity is 0.077m
3/ min.Attracting the aperture area in hole 30 is 64mm
2, therefore attracting the hole wind speed is 20m/sec, can bring into play sufficient attraction.At this moment, with regard to the flowing resistance of filter for installation 8 each one, (attracting hole flowing resistance r1+ suction nozzle flowing resistance r2) is 39mmAq, (attraction pipeline flowing resistance r3) is 15mmAq, (suction device flowing resistance r4+ discharge duct flowing resistance r5) is 9mmAq, and it is 63mmAq that flowing resistance adds up to R.This means that suction device 20 can only attract to add up to the flowing resistance of 63mmAq.At this moment, with regard to the inside wind speed of filter for installation 8 each one, by air quantity and each ventilation road sectional area as can be known, the inner wind speed of suction nozzle is 5.1m/sec, and the inner wind speed of attraction pipeline is 5.6m/sec, and the inner wind speed of discharge duct is 2.6m/sec.Want to carry dust, the minimum 7.0m/sec that also needs of inner wind speed, therefore, the dust on the air cleaner then is deposited in suction nozzle 14 inside if attracted by suction nozzle 14.
Next, carry out the phase I of the discharging operation that brings by the expansion of suction nozzle 14 aperture areas action.At this moment, attracting the total aperture area of the assist openings portion 34 of hole 30 and suction nozzle 14 is 120mm
2, therefore, the peristome wind speed decreased attracts hole flowing resistance r1 to descend, and consequently, air quantity increased always before the flowing resistance of filter for installation 8 each one amounted to 63mmAq.In the present embodiment, air quantity increases to 0.11m
3/ min, the peristome wind speed of this moment is 15.2m/sce.With regard to the flowing resistance of filter for installation 8 each one, (attracting hole flowing resistance r1+ suction nozzle flowing resistance r2) is 13mmAq, (attraction pipeline flowing resistance r3) is 31mmAq, (suction device flowing resistance r4+ discharge duct flowing resistance r5) is 19mmAq, it is 63mmAq that flowing resistance adds up to R, does not change during with the attraction cleaning.At this moment, with regard to the inside wind speed of filter for installation 8 each one, by air quantity and each ventilation road sectional area as can be known, the inner wind speed of suction nozzle is 7.3m/sec, the inner wind speed of attraction pipeline is 8.1m/sec, the inner wind speed of discharge duct is 3.7m/sec, and suction nozzle dust inner and attraction pipeline inside is transferred, and is pushed to discharge duct 22 through suction device 20 and flows.But the inside wind speed of discharge duct 22 is 3.7m/sec, and below the 7.0m/sec that can carry dust, therefore, dust is piled up once more at this.
Then, carry out the second stage of the discharging operation that the opening action by the peristome 44 of suction device 20 brings.At this moment, the aperture area of suction device 20 is 750mm
2, therefore, the wind speed in the peristome 44 is very low, and (suction device flowing resistance r4) is also very low.On the other hand, (attracting hole flowing resistance r1+ suction nozzle flowing resistance r2) and (attraction pipeline flowing resistance r3), flowing resistance does not exist because therefore wind do not flow.As a result of, air quantity increased always before (suction device flowing resistance r4+ discharge duct flowing resistance r5) arrived 63mmAq.In the present embodiment, air quantity increases to 0.235m
3/ min, the peristome wind speed of the suction device 20 of this moment is 5.2m/sce.With regard to the flowing resistance of filter for installation 8 each one, (attracting hole flowing resistance r1+ suction nozzle flowing resistance r2) is 0mmAq, (attraction pipeline flowing resistance r3) is 0mmAq, (suction device flowing resistance r4+ discharge duct flowing resistance r5) is 63mmAq, it is 63mmAq that flowing resistance adds up to R, does not change during with the attraction cleaning.At this moment, with regard to the inside wind speed of filter for installation 8 each one, by air quantity and each ventilation road sectional area as can be known, the inner wind speed of discharge duct is 8.0m/sec, and the dust that is deposited in discharge duct inside is pushed and flows and to outdoor discharge.
So, carry out described a succession of action in turn, also can discharge dust reliably with the suction device 20 of little output by control suction nozzle 14, suction device 20 etc.In addition, also can increase the sectional area on the ventilation road of suction nozzle 14 or pipeline 18,22, the flowing resistance when reducing to attract to clean as far as possible can realize powerful attraction clean-up performance simultaneously and prevent the dust accumulation.
Also have, adopt the discharging operation in 2 stages in the present embodiment, but, also can for example in attraction pipeline 18 ways, open and close valve be set, carry out the discharging operation in 3 stages, 4 stages.
Utilizability on the industry
As mentioned above, the filter for installation of air conditioner of the present invention can attract to clean rear increase Attract air quantity, with the dust of filter for installation inside to outdoor discharge, therefore, can be with little output Suction device is guaranteed simultaneously powerful attraction and is discharged reliably dust.
