Abstract

Suction is gathered up into a suction hole by arranging a driveable belt with small suction holes opened thereon in the suction nozzle, and output of the suction device can be largely reduced by reducing the suction air volume while maintaining strong suction force. A sucking place is also varied by moving the suction holes by driving the belt, and the whole air filter area is cleaned by performing sweeping operation on the air filter in response to operation of the suction nozzle.

Therefore, burden for the maintenance that reduces air cleaner, someone motion be provided with the air cleaner of hanging up the band shape on driving shaft and with the surperficial contacted rotating brush of this air cleaner, rotating driveshaft and air cleaner is moved on one side, by make rotating brush rotation will be deposited in air conditioner that its lip-deep dust brush away on one side.(reference example such as patent documentation 1).

Patent documentation 1: the spy opens flat 6-74521 communique

Yet should before technology in because brush and air cleaner are rubbed mutually, accumulate dust, and brush wearing and tearing or be out of shape and cause dust removal performance to hang down inferior problem thereby produced on the brush.In addition, passed through after the regular hour, must handle the dust that brush brushes away and collects, therefore significantly do not alleviated the burden of maintenance.In addition, because brush is corresponding to the whole width setting of air cleaner, so in order to make the brush rotation that bigger moment of torsion must be arranged, therefore make the drive unit of brush become big, in order to ensure its accommodation space, produced and to have made indoor set this problem that maximizes.

From the above point of view,, preferably will sop up attached to the dust on the air cleaner, and focus on the dust that is drawn onto in the dust collect plant or be discharged to outdoor by suction nozzle as the automatic cleaning device of air cleaner.

In this method, on suction nozzle, be provided with the long slit-shaped that length is equivalent to the length overall of air cleaner for whole of cleaning air filter and inhale the hole, by inhaling the hole dust accompanying on the air cleaner is attracted to remove, but under situation about attracting from whole suctions hole scope, exist and attract air quantity to become big, it is very big that the output of suction device becomes, and not only will consume a lot of power, and be difficult to this suction device is built in inner this problem of main frame of indoor set.

Summary of the invention

The present invention proposes in view of the problem points that was had in the former technology, and purpose provides a kind of air conditioner of the easy maintenance that can clean air cleaner by little output and small-sized suction device.

In addition, another object of the present invention provides a kind of air conditioner with ventilatory.

For achieving the above object, air conditioner of the present invention is characterised in that, have and be provided with heat exchanger, attraction by the drivable nozzle unit of the dust of the air of this heat exchanger and the suction device that is connected with this nozzle unit, nozzle unit has the peristome that is arranged on the suction nozzle, and cover this peristome simultaneously can be along the driven dust suction band of peristome, the dust suction band is provided with the suction hole as attraction portion, can set by driving the dust suction band to attract the position with changing.

By such formation, because concentrating on, the attraction of suction device inhales the hole, attract air quantity thereby can when keeping strong suction, reduce, and significantly reduce the output of suction device.In this case, what can attract to clean only is the heat exchanger part that is positioned at the below in the suction hole that is arranged on the dust suction band, yet, nozzle unit moves and drives the dust suction band by being come and gone, switch the position of inhaling the hole in turn, the very little suction device of output can clean the region-wide of heat exchanger, even also can fully attract the region-wide of cleaning air filter.

In addition, preferably make the thickness of dust suction band thin as much as possible, action when making driving dust suction band by it is approached is more level and smooth, simultaneously sealed because the position beyond the suction hole of dust suction band is attracted on the nozzle openings, the attraction that therefore can suppress to inhale beyond the hole is leaked, and the suction that prevents to inhale the hole is low.

Yet under the situation of using extremely thin dust suction band,, therefore preferably make the grade part of dust suction band of the both ends of dust suction band thicker because the intensity of dust suction band might be lowered.Like this, can keep sealing, make the dust suction band have given intensity simultaneously.

In addition, preferably make the suction hole of dust suction band thicker on every side.Because the dust suction band is stretched when driving, split easily by the suction bore portion of opening, inhale the thicker of hole on every side by making, can use thin dust suction band and prevent to inhale bore portion and split.

In addition, if along the dust suction band brush is set in nozzle unit, only the dust by attract cleaning can't thoroughly be removed of close attachment on air cleaner just can utilize the brush power of brush and be eliminated.

In addition, best mode according to clamping dust suction band is provided with guide in the nozzle unit.Like this, can prevent the dislocation of dust suction band position, can also suppress floating of dust suction band simultaneously, make the position in addition, suction hole of dust suction band be adsorbed and seal reliably.

In addition, by driving the said suction nozzle device, can more fully remove dust by heat exchanger along air cleaner with the dust that removes the air by heat exchanger.

In addition, preferably make dust suction tape guide device extend to the near surface of air cleaner.Under the situation on the surface of passing through the attraction cleaning air filter, along with leaving from inhaling the hole, suction sharply reduces.Because it is near more good more from the surface of air cleaner to inhale the hole, therefore can bring into play strong attraction cleaning performance by the near surface that makes guide extend to air cleaner.

In addition, the part along the dust suction band in nozzle unit is provided with under the situation of brush, preferably make dust suction tape guide device extend to brush near.Like this, can prevent the reduction of suction, dust accompanying on the brush can also be absorbed simultaneously that can keep nozzle unit is clean conditions

In addition, a plurality of suctions hole that varies in size can also be set on the dust suction band.By using these to inhale the hole respectively, can under the certain state of the output that keeps suction device, use different suction respectively according to amount attached to the dust on the heat exchanger, by being set, big suction hole can also take a breath in addition by nozzle unit.

In addition, if the function that changes the output of suction device according to the size in position of inhaling the hole and suction hole is set, just can change suction, the air quantity of ventilation usefulness etc. perhaps is set, be suitable for the setting of different states according to amount attached to the dust on the heat exchanger.

In addition, air conditioner of the present invention is characterised in that, have the air cleaner that is provided with heat exchanger, collects the dust that is contained in the air that flows into this heat exchanger, the nozzle unit that can move and the suction device that is connected with this nozzle unit along the upstream side surface of this air cleaner, be provided with in the nozzle unit and can on the direction vertical, move, and have the dust suction band of the film shape of inhaling the hole with the moving direction of nozzle unit.

By such formation, only by mobile nozzle unit and dust suction band, just can carry out the region-wide attraction of accompanying dust of air cleaner, simultaneously owing to can make the aperture area of inhaling the hole less, also can keep strong suction and reduce the attraction air quantity even therefore the output of suction device is less, thereby can make the suction device miniaturization.

In addition, if make nozzle unit have relative with the upstream side of air cleaner surface to and the peristome of opening, the dust suction band covers peristome and can move along peristome simultaneously, and the dust suction band is supported by a plurality of cylinder and utilizes gear to move, just can be smoothly and mobile exactly dust suction band.

In addition, be used for pressing the cylinder of dust suction band by near setting gear, can increase be arranged on the dust suction band on the drive hole interlock number of teeth of the gear of interlock mutually, can drive the dust suction band more smoothly.

In addition,, can prevent that the suction hole of dust suction band from staggering from the peristome that is arranged on the suction nozzle in nozzle unit by the guiding groove of guiding dust suction band is set, can mobile smoothly dust suction band, carry out good attraction cleaning simultaneously.

In addition,, just can reduce the space that cylinder is installed, thereby enlarge the area in the air channel in the suction nozzle, therefore can improve suction if in a plurality of cylinders that support the dust suction band, make to have 1 place at least by usefulness that pin replaces.

Perhaps, can also make in a plurality of cylinders that support the dust suction band, the lip-deep smooth lug boss that has at least 1 place to be formed on nozzle unit replaces usefulness, in this case, can further enlarge the air channel area and improve suction, owing to can make the outstanding minimizing of the bend of suction nozzle, can improve its taking in property in the indoor set main frame simultaneously.

In addition, if in a plurality of cylinders that support the dust suction band, the elastomer that applies elastic force on the direction of the above-mentioned dust suction band of tensioning is set at least one cylinder, the dust suction band that just can absorb caused deviation such as the size of the each several part that constitutes nozzle unit and assembling and cause lax, mobile dust suction band under stable status always.

In addition, air conditioner of the present invention is characterised in that, be provided with heat exchanger, collect the air cleaner of the dust that is contained in the air that flows into this heat exchanger, the nozzle unit that can move and the suction device that is connected with this nozzle unit along the upstream side surface of this air cleaner, have the suction hole that is used to attract dust in the nozzle unit, and the suction hole opening-closing plate that can change the aperture area of inhaling the hole.

According to such formation, open a part of inhaling the hole in turn by inhaling the hole opening-closing plate, mobile nozzle unit attracts on one side on one side, can reduce to attract air quantity, guarantee to inhale the strong suction on the hole, reduce the attraction air quantity simultaneously, thereby can carry out attraction cleaning by the suction device of low-power to the full surface of air cleaner.In addition, if will inhale the hole and all open and attract by inhaling the hole opening-closing plate, and just can reduce the wind speed of inhaling in the hole and also significantly reduce windage, even the output of while suction device is identical, air quantity also can increase, and can utilize this point to carry out the ventilation of the air in room.In addition, inhale the hole Close All by making, in the time of can preventing the suction device standby in the generation of the adverse current of the air of suction nozzle side.

In addition, come and go the aperture area that moves and change the suction hole in the horizontal direction with respect to inhaling the hole, just can make nozzle unit thinner, thereby can prevent the maximization of indoor set main body if make suction hole opening-closing plate.

Perhaps, inhale the hole opening-closing plate with respect to inhaling the aperture area that the hole rotates and change the suction hole, just can make the thin and simple structure of nozzle unit, thereby can prevent the maximization of indoor set main body if make, and can the qurer formation.

In addition, inhale the hole opening-closing plate and move or rotation and change the aperture area of inhaling the hole if make with respect to inhaling the hole in vertical direction and coming and going, owing to can make the width of nozzle unit less, so can suppress the reduction of the caused air quantity by heat exchanger of suction nozzle, can also reach performance satisfactory to both parties of the built-in and air conditioner of nozzle unit simultaneously.

In addition, be carried in the spring of closing the elastic force on the direction of inhaling the hole if be provided with to inhaling the hole opening-closing plate, and the wire that is connected with above-mentioned suction hole opening-closing plate, driving above-mentioned wire resists the elastic force of above-mentioned spring and carries out moving or rotation of above-mentioned suction hole opening-closing plate, just can use the fine wire transmission of drive force, thereby can make the structure of suction nozzle thinner, suppress because of adding the maximization of the caused indoor set main body of suction nozzle.

In addition, inhale the driving of hole opening-closing plate, can also be by being formed on the saw shape tooth of inhaling on the opening-closing plate of hole, and have and this saw shape tooth motor of the gear of interlock mutually, perhaps be formed on the thread groove of inhaling on the opening-closing plate of hole, and have with this thread groove mutually the motor of the rotating shaft of interlock carry out.At this moment, can be strong and inhale the on-off action of hole opening-closing plate exactly, prevent decline because of the bad attraction cleaning performance that causes of on-off action of inhaling the hole.

In addition, if peripheral part of inhaling the hole opening-closing plate with inhaling the hole relative to part on encapsulant is set, even inhale the hole around just in case also can seal reliably when being attached with foreign matter such as dust.Therefore, when carrying out dust suction,, also can prevent to attract to leak even other suction hole is under the incomplete closure state because of foreign matter etc. by the suction hole of a part, and the reduction that attracts cleaning performance.

The specific embodiment

The contrast accompanying drawing describes embodiments of the present invention below.

Embodiment 1

The installation portion of the air cleaner in the indoor set of the relevant air conditioner that is arranged on embodiments of the present invention 1 has been described among Fig. 1～Fig. 8.

As shown in Figure 1, the usefulness that is configured in the upstream side of heat exchanger (not shown) removes the air cleaner of the dust that is contained in the air of inflow heat exchanger, constitute by filter frame 1 and screen pack 2, be provided with the nozzle unit 3 that can move along the surface of air cleaner.The guide rail 4 of the upper and lower side of nozzle unit 3 by being arranged on filter frame 1, can and air cleaner between keep extremely narrow gap and about level and smooth moving.Dust accompanying on the air cleaner is absorbed by this nozzle unit 3.

At an end (lower end) of nozzle unit 3, be connected with a end by the formed attraction air channels 5 such as snake abdomen shape flexible pipe of flexible excellence, attract the other end in air channel 5 to be connected with the suction device 6 that is built-in with the electric blowing machine (not shown).In addition, be connected with exhaust duct 7 in the suction device 6, to outdoor discharge.The dust of the air cleaner that is attracted by nozzle unit 3 is discharged to outdoor through attracting air channel 5, suction device 6, exhaust duct 7.

Below with reference to Fig. 2～Fig. 4 the formation of nozzle unit 3 is elaborated.Fig. 2 is the figure that see nozzle unit 3 from oblique upper for the figure of the structure of the nozzle unit 3 in the above-mentioned dust arrester of explanation.Nozzle unit 3 main by constituting the suction nozzle 8 of the passage of air draught, and the dust suction band 9 of the film shape of the wide 20mm that is provided with around suction nozzle 8 constitutes.On the face of the air cleaner side of suction nozzle 8, be provided with long for example 320mm (lengthwise that is equivalent to air cleaner), the nozzle openings portion 10 of the slit-shaped of wide for example 3mm.In addition, dust suction band 9 forms in the form of a ring, is wrapped in the peripheral of suction nozzle 8 and nozzle openings portion 10 is covered.Dust suction band 9 length for example are 80mm (lengthwise of air cleaner 1/4), are provided with for example wide suction hole 11 of 2mm, according to making the mode of position directly over nozzle openings portion 10 of inhaling hole 11 that dust suction band 9 is installed.The two ends of dust suction band 9 are provided with the equally spaced drive hole 12 as the cinefilm, by making the gear of being installed on the stepper motor 13 that is fixed on the suction nozzle 8 14 and this drive hole 12 interlock mutually, move freely along any direction up and down and can drive dust suction band 9.

Fig. 3 is the schematic diagram (cross section of A portion among Fig. 2) in the cross section of explanation nozzle unit 3 for the schematic diagram of the suction nozzle 8 in the difference key diagram 2 with dust suction band 9, Fig. 4.

In addition, as other formations that drive dust suction band 9, can also not use gear 14 and wait by rubber cylinder and to drive dust suction band 9.

In addition, in the present embodiment, dust suction band 9 is formed ring-type, but also can adopt the method that spool gets up the dust suction roll coil of strip that is provided with for the miniaturization of implement device.

By above-mentioned formation, owing to the air quantity that is attracted by suction device 6 is concentrated through inhaling hole 11, even therefore less air quantity also can inhaled the stronger wind speed of generation on 11 parts of hole.Also promptly, can be with little output performance strong suction.Dust on the air cleaner that this strong suction attracted from inhaling hole 11 through the inside that nozzle openings portion 10 enters suction nozzle 8, further is discharged to outdoor through attraction air channel 5, suction device 6, exhaust duct 7.

In the present embodiment,, contrast Fig. 1, Fig. 5, Fig. 6, Fig. 7 below because the full surface of 3 pairs of air cleaners of nozzle unit of as above being constituted cleans, Fig. 8 describes its concrete action.Fig. 5 is the schematic diagram (from the back side see the figure of suction nozzle) of explanation corresponding to the position in the suction hole of the cleaning range I～IV of the air cleaner shown in Fig. 1.In addition, actual nozzle unit 3 is the bending along air cleaner as shown in Figure 1, and what show for the ease of watching among Fig. 5 is the state that suction nozzle is stretching.

At first, when the scope I of the air cleaner of cleaning among Fig. 1, drive dust suction band 9 and will inhale on the position I that hole 11 is fixed on Fig. 5.By under this state while attracting that nozzle unit 3 is driven into left end from the right-hand member of air cleaner, can attract to clean the scope I of the air cleaner among Fig. 1.

Next, for the scope II that transfers to the air cleaner among Fig. 1 cleans, drive dust suction band 9 and will inhale on the position II that hole 11 is fixed on Fig. 5.Equally, while, can attract to clean the scope II of the air cleaner among Fig. 1 specifically by attracting that under this state nozzle unit 3 is driven into right-hand member from the left end of air cleaner.By same method, the scope III of the air cleaner among Fig. 1, IV also can be attracted cleaning.

The order of having represented this attraction cleaning among Fig. 6 with arrow attracts action to clean the full surface of air cleaner by carrying out such transverse scan.

Air quantity in the present embodiment is compared with situation about attracting from nozzle openings portion gamut, air quantity be its 1/4, because needed power is directly proportional with 3 powers of air quantity, thus can be reduced to 1/64, so the very little power of 6 needs of suction device is just passable.

In the present embodiment, dust suction band 9 is provided with the suction hole 11 of lengthwise, carry out the attraction cleaning of transverse scan as shown in Figure 6, much less can also adopt the suction hole 11 that setting is grown crosswise on dust suction band 9 as shown in Figure 7 certainly, the method for cleaning by the frame scan shown in Fig. 8.

(variation 1)

The thickness of dust suction band 9 is preferably thin as much as possible, by making the thin flexibility that can guarantee its sweep (the particularly top ends of nozzle unit 3 and root) of dust suction band 9, thus the drive actions of carrying out dust suction band 9 that can be level and smooth.In addition, by making dust suction band 9 thinner, inhale hole 11 parts dust suction band 9 in addition, owing to suction connects airtight in nozzle openings portion 10, thereby sealing can suppress to inhale hole 11 attraction in addition and leak the reduction that prevents to attract to leak the suction on the caused suction hole 11.From aspects such as above-mentioned this respect and durability, intensity, preferably use thin plastic sheeting as dust suction band 9.Yet under the situation of using thin dust suction band, because the intensity of dust suction band reduces the tension force that might bear when driving.In this case, thicker by a part that makes dust suction band 9, the flexibility in the time of can not damaging driving and the sealing of dust suction band, and improve intensity.

Fig. 9 is the sectional view of the variation of dust suction band 9, and dust suction band 9 is by adopting for example thin plastic sheeting of thick 0.1mm, and the thickness that makes its two end portions can be guaranteed full intensity for example for 0.2mm.In addition, in this dust suction band 9, equally spaced drive hole 12 parts of opening on dust suction band 9 are thicker too, can guarantee the transmission to the driving force of drive hole 12.

(variation 2)

On the basis of the shape of variation 1, improve the thickness of the dust suction band 9 around the suction hole set on the dust suction band 9 11, also beneficial to the intensity that improves dust suction band 9.As mentioned above, dust suction band 9 preferably uses thin plastic sheeting, under the situation of using thin plastic sheeting, because the intensity of dust suction band reduces the tension force that might bear when driving.The intensity that the dust suction band 9 of hole 11 parts of living in is promptly inhaled in particularly bigger hole can significantly reduce.In this case, inhale the thicker of hole 11 on every side, can improve the intensity of the dust suction band 9 of inhaling hole 11 parts of living in by making.

Among Figure 10, shown the sectional view of another variation of dust suction band 9,, also can guarantee full intensity even inhale the dust suction band 9 of hole 11 parts of living in by making peripheral part of inhaling hole 11 for example for 0.2mm is thick.

(variation 3)

The variation that has shown nozzle unit 3 among Figure 11～Figure 13 is particularly carried out employed formation under the situation of frame scan cleaning by the suction hole of growing crosswise 11 shown in Fig. 7 and Fig. 8.

In the nozzle unit 3, brush 15 is along dust suction band 9 landscape configuration, and brush 15 can use the short nylon loop (so-called etiquette brush) of hair etc.Because brush 15 close attachment on air cleaner, can will only be brushed by the dust that attracts cleaning thoroughly to remove, therefore utilize this effect can carry out more high performance screen pack cleaning.In the method for using brush 15 to attract to clean, being shaped as of the suction hole 11 of dust suction band 9 grow crosswise shape and the situation (with reference to figure 7, Fig. 8) of cleaning by the frame scan action more satisfactory, so also adopted this shape in this variation.

In this case, as shown in figure 13, nearly all dust all at first is attracted cleaning and removes, and does not have removed dust to begin brush from behind by brush 15 again and falls, so this method is very desirable.In addition, be under the situation of lengthwise inhaling hole 11, by configuration brush 15, transverse scan action as shown in Figure 6 is difficult to carry out (because the locational dust of inhaling beyond the hole 11 only cleans by brush 15, so undesirable), but can carry out the air cleaner cleaning by improving action.In this case, as shown in figure 14, at first make nozzle unit 3 remove certain distance and brush away dust by brush 15.Suction hole 11 is moved 1 time near the position of the dust of being brushed up and down, thereby inhale the dust that goes brush 15 to be brushed.Like this, can bring into play brush 15 and the effect that attracts both sides, air cleaner is cleaned.

(variation 4)

Figure 15 is the sectional view of another variation of explanation nozzle unit 3.It is the same with above-mentioned formation to be provided with dust suction band 9 this point around the suction nozzle 8.In this variation, further be formed with the structure that extends dust suction tape guide device 16 from suction nozzle 8 with the form of clamping dust suction band 9 at the back side of suction nozzle 8 (side of inhaling hole 11 is arranged).

By such formation, can prevent the dislocation of the position of dust suction band 9, the dust suction band 9 that can also prevent from simultaneously to inhale the part beyond the hole 11 floats from suction nozzle 8, can make 9 sorptions of dust suction band in the nozzle openings portion 10 described in the variation 1 and sealing reliably.

In addition, as shown in figure 15, dust suction tape guide device 16 preferably extends to the position of inhaling hole 11.Like this, the diffusion of the suction in self-priming hole 11 can be prevented from, thereby stronger suction can be kept.

(variation 5)

Figure 16 is the sectional view of another variation of explanation nozzle unit 3, and the dust suction tape guide device 16 in the above-mentioned variation 4 has extended to the near surface of air cleaner.By when attracting the surface cleaning of air cleaner, suction is along with from inhaling that hole 11 is left and sharply reducing.This is because flowing of the air that attracted inhaled hole 11 and spread along with leaving, and it is near more good more from the surface of air cleaner therefore to inhale hole 11.Yet, in the formation of indoor set, must have apart from air cleaner under the situation of certain distance, extend to the air cleaner near surface by making dust suction tape guide device 16 at nozzle unit 3, can prevent the diffusion of institute's suck, at air cleaner near surface performance strong suction.

(variation 6)

Figure 17 is the sectional view of another variation of explanation nozzle unit 3, and in the nozzle unit 3 of illustrated brush 15, dust suction tape guide device 16 extends near near the air cleaner in using variation 3, and near brush 15 places.By such formation, can access effect illustrated in the variation 5 at the surface of air cleaner performance strong suction, can also obtain dust accompanying on the brush 15 is attracted the effect of removal simultaneously, can keep nozzle unit 3 to be clean conditions.

(variation 7)

Figure 18 and Figure 19 are the figure of the detailed construction of another variation of detailed description nozzle unit 3.Component parts is identical with the nozzle unit 3 shown in Fig. 2 and Fig. 3, the wider width of the nozzle openings portion 10 of suction nozzle 8 (for example wide 10mm).In addition, also be provided with a macropore with attracting cleaning with inhaling on the opposite position, hole 11 (for example wide 2mm, long 80mm) on the dust suction band 9 as the long 80mm of for example wide 10mm of air-vent 17.

In such formation, under the situation that attracts to clean, as shown in figure 18, drive dust suction band 9 and make suction hole 11 be positioned at nozzle openings portion 10 sides of suction nozzle 8 usually.Under this state, air-vent 17 is positioned at the upper surface side of suction nozzle 8, cuts little ice, so similarly can attract cleaning by inhaling hole 11 with the situation of Fig. 2 and Fig. 3.

In addition, as shown in figure 19, dust suction band 9 is rotated to the opposition side of inhaling hole 11, drive dust suction band 9 and make air-vent 17 be positioned at nozzle openings portion 10 sides of suction nozzle 8.Under this state, be that suction hole 11 is inoperative specifically, though attract through air-vent 17, because air-vent 17 is compared the sizableness big (for example 5 times) of its peristome with suction hole 11, the attraction of the low and low noise of the big windage of air quantity can be carried out, ventilatory can be used as.In addition, nozzle unit 3 does not need to carry out scanning motion during ventilation.

Like this, inhale hole 11 and air-vent 17 these two suction holes that vary in size, can make nozzle unit 3 have the cleaning of attraction and these two functions of ventilation by on dust suction band 9, being provided with.

In addition, be provided with 2 in this variation and inhale hole 11,17, if dust suction band 9 is not above-mentioned ring-type but is wound on the spool, then because dust suction band 9 can be longer, therefore more much little different suction holes can be set, use different suction inlets according to the amount and the type selecting of dust accompanying on the air cleaner.

(variation 8)

Embodiment 3

The oblique view of the installation portion of set air cleaner in the indoor set of relevant air conditioner of Figure 30 for explanation embodiments of the present invention 3 describes the point different with above-mentioned embodiment 1 below.

On the face of the air cleaner side of nozzle unit 3, be provided with for example nozzle openings portion 10 of the slit-shaped of wide 2～3mm, attract accompanying dust on the air cleaner by nozzle openings portion 10.In the present embodiment, the dust suction band 9 of film shape set in above-mentioned embodiment 1 or the embodiment 2 is not set.

Figure 31 is the in-built summary oblique view of explanation nozzle unit 3.Nozzle unit 3 is the shape along the air cleaner bending as shown in figure 30, but for explanation is easier to, shown among Figure 31 is the state that nozzle unit 3 is stretched.

As shown in figure 31, the nozzle openings portion 10 that is arranged on the nozzle unit 3 is divided into suction hole 10a, inhales hole 10b, inhales hole 10c, inhales these 4 parts of hole 10d.

Be provided with in the nozzle unit 3 with each and inhale the corresponding and round in the horizontal direction suction hole opening-closing plate 31a～31d that is used for opening and closing suction hole 10a～10d that moves of hole 10a～10d.

What show among Figure 31 is to inhale among the 10a～10d of hole, has only the hole 10a of suction to open the state of other suction hole 10b～10d closure.Under the situation that turns round suction device 6 under this state, attracts, flowing shown in the white arrow among the figure of the wind that is attracted only is attracted at suction hole 10a.

Have only the hole 10b of suction to open among Figure 32, other suction hole 10a, 10c, 10d closure only attract by inhaling hole 10b.Suction hole 10c, 10d are opened.

Concrete action when attracting to clean by 3 pairs of air cleaners of nozzle unit of as above being constituted region-wide describes below.

At first, as shown in figure 31, by suction hole opening-closing plate 31a being moved right and only will inhaling hole 10a and open, while making nozzle unit 3 come and go along guide rail 4, moves by the suction device 6 that turns round, can on the Zone Full of the scope I that inhales the pairing air cleaner of hole 10a, attract cleaning.

Next shown in figure 32, by suction hole opening-closing plate 31a being moved to the left and will inhaling hole 10a and close, make simultaneously and inhale hole opening-closing plate 31b and move right and will inhale hole 10b and open, while the suction device 6 that turns round nozzle unit 3 is come and gone moves, can attract cleaning on the Zone Full of the scope II that inhales hole 10 pairing air cleaners along guide rail 4.Close suction hole 10b equally in order and open suction hole 10c, close suction hole 10c and open suction hole 10d, attract running, thereby scope III, the IV of attraction cleaning air filter finish the attraction on the full surface of air cleaner and clean.

In such formation, by each air quantity of inhaling the hole be decreased to use complete inhale the hole when attracting (inhale hole 10a～10d and all open the situation of running) air quantity 1/4, attract the area of opening reduced, so can guarantee that each wind speed of inhaling hole 10a～10d is necessary wind speed, can obtain sufficient suction.

Here, to all suction hole 10a～10d are all opened, necessary power under situation about attracting simultaneously under the required wind speed, with will inhale hole 10a～10d and open the necessary power of situation about attracting one by one and compare, because necessary power is directly proportional with 3 powers of air quantity, therefore necessary power can be reduced to 1/64.Like this, suction device 6 necessary power only need very little just much of that, thereby can realize the miniaturization of suction device 6.

In addition, if will inhale hole 10a～10d all opens, make all aperture areas become big, because the wind speed decreased of this part can make that windage declines to a great extent, even therefore the output of suction device 6 is identical, air quantity also significantly increases (because suction declines to a great extent, can not attract certainly) under this state.Utilize this point, the room necessary air quantity of taking a breath is flowed into from nozzle unit 3, thereby can utilize nozzle unit 3 and make air conditioner have ventilatory.

In addition, when suction device 6 is in halted state (holding state), if the outdoor high wind of blowing, might wind can be from entering nozzle unit 3 with the outdoor exhaust duct that is connected 7 adverse currents, thereby nozzle unit 3 inner accompanying dusts are ejected, just can prevent such adverse current by inhaling hole 10a～10d Close All in this case.

As mentioned above,, can not only realize the miniaturization of suction device 6, can also make nozzle unit 3 have ventilatory in addition, and adverse current prevent function according to present embodiment.

In addition, shown in present embodiment, will inhale hole opening-closing plate 31a～31d and be built in the nozzle unit 3, and can come and go and to move relative to inhaling hole 10a～10d level, and can make the structure of nozzle unit 3 thinner, the change of inhibition indoor set main body be big.In addition, as shown in figure 30,, also can constitute without a doubt, can in the design of nozzle unit 3, have the suitable free degree even nozzle unit 3 is " L " word sigmoid.

Figure 33 is the in-built summary oblique view of the nozzle unit 3 in the explanation present embodiment, is illustrated inhaling hole 10c, 10d especially.

Inhaling hole 10c among the figure is closed condition, and inhaling hole 10d is open mode.Inhale to be provided with separately respectively on the opening-closing plate 31a～31d of hole it is applied a pair of spring 41 of closing the elastic force on the direction of inhaling hole 10a～10d, and the spring force of the antagonistic spring 41 and wire 42 that stretches is inhaled hole opening-closing plate 31a～31d and is fixed on the closing position because of the elastic force of spring 41 usually.

When opening each and inhaling hole opening-closing plate 31a～31d, the elastic force of antagonistic spring 41 and stretched wire 42, as the method for stretched wire 42, can adopt by the motor (not shown) and reel or the method etc. of usage operation line (by energising can access the effect of wire contracts, stretching to wire) in wire 42.

According to this method, by in driving force is transmitted, using fine wire 42, can make the structure of nozzle unit 3 thinner, suppress because of adding the maximization of the indoor set main body that nozzle unit 3 caused.

In addition, be in the specification of straight (flat) at nozzle unit 3, as shown in figure 34, can be that the center is rotated and opens and closes each and inhale hole 10a～10d by end of inhaling hole opening-closing plate 31a～31d with each.Constitute by so further simplification, can suppress expense, owing to can reduce the barrier of the passage of dust, therefore can also reduce windage simultaneously.

Except adopting above-mentioned spring 41 and wire 42 to drive the method for inhaling hole opening-closing plate 31a～31d, can also be as shown in figure 35, saw shape tooth 44 is set on each inhales hole opening-closing plate 31a～31d, by motor 46 drive with this saw shape tooth 44 mutually the gear 45 of interlock drive suction hole opening-closing plate 31a～31d.

Perhaps, as shown in figure 36, can inhale on the opening-closing plate 31a～31d of hole, the inner riser 48 of cutting thread groove is installed, and run through the thread groove rotating shaft 49 of interlock mutually with this riser 48, drive rotating shafts 49 by motor 50 and drive at each.

According to these methods, can inhale the on-off action of hole opening-closing plate 31a～31d strong and reliably, thereby can prevent reduction because of the bad caused attraction cleaning performance of on-off action of inhaling hole 10a～10d.Perhaps, though specially do not show in the drawings, can also use electromagnet or servo motor to drive each and inhale hole opening-closing plate 31a～31d.

(variation 1)

Figure 37 is the part oblique view of the variation of explanation nozzle unit 3.

In the formation shown in Figure 31～Figure 36, the action of inhaling hole opening-closing plate 31a～31d is not that hole 10a～10d is round in the horizontal direction to be moved relative to inhaling, make its rotation exactly, and in the formation shown in Figure 37, each is inhaled hole opening-closing plate 31a～31d and has been loaded to the elastic force of closing the direction of inhaling hole 10a～10d by spring 41 respectively, make by wire 42 simultaneously and inhale hole opening-closing plate 31a～31d, open and close each and inhale hole 10a～10d along round the moving of direction (separation direction of engagement) of inhaling hole 10a～10d perpendicular to each.

Perhaps as shown in figure 38, each one side (being the left side among the figure) of inhaling hole opening-closing plate 31a～31d is rotated freely and supports, in addition, add the elastic force of the direction of closing each suction hole 10a～10d by torsionspring 52, make each inhale hole opening-closing plate 31a～31d by the elastic force of wire 53 antagonistic springs 52 and rotate, open and close each and inhale hole 10a～10d.

In the mode shown in Figure 37 and Figure 38, employed in the driven for opening and closing of each suction hole opening-closing plate 31a～31d all is spring and wire, can also adopt with reference to the illustrated use saw shape tooth of Figure 35 or Figure 36 or the method for rotating shaft, can also adopt the method for using electromagnet in addition.

In the above-mentioned formation, moving relative to the vertical direction of each suction hole 10a～10d by making each inhale hole opening-closing plate 31a～31d, comparing with situation about moving horizontally does not need to be used for the space that each inhales the round action of hole opening-closing plate 31a～31d.Therefore, can make the transverse width of nozzle unit 3 less, thereby can suppress, can realize performance satisfactory to both parties of the built-in and air conditioner of nozzle unit 3 because of nozzle unit 3 hinders circulation air quantity by the heat exchanger of indoor set, causes air quantity to reduce.

(variation 2)

Figure 39 is the sectional view of another variation of nozzle unit 3, is the E-E sectional view of Figure 37.

Inhale hole opening-closing plate 31a～31d by each and close when inhaling hole 10a～10d, preferably sealing fully suppose to inhale on the 10a～10d of hole and is attached with foreign matter, inhales hole opening-closing plate 31a～31d when closing and will become a little float state, can therefrom produce to attract leakage.Therefore, even any one among suction hole 10a～10d in opened condition, also can decline to a great extent because of this part causes suction.

Shown in Figure 39 constituting can prevent to attract the structure of leaking, and the part of joining with each periphery of inhaling hole 10a～10d of inhaling hole opening-closing plate 31a～31d at each is posted by the made encapsulant 55 of elastomeric material.

By such formation, shown in Figure 39 (a), even inhale on the 10a～10d of hole and be attached with foreign matter, shown in Figure 39 (b), when closing by suction hole opening-closing plate 31a～31d, because the strain of the encapsulant 55 and slit is clogged can prevent to attract to leak, thereby guarantee sufficient attraction performance on the suction hole of open mode.

(variation 3)

Figure 40 is the summary oblique view of another variation of nozzle unit 3.

As mentioned above, by suction hole 10a～10d is all opened, can make the room take a breath needed air quantity through nozzle unit 3 inflows, but in this case, for the ventilation air quantity is increased, preferably reduce the wind speed that each inhales hole 10a～10d as far as possible, therefore preferably make each width of inhaling hole 10a～10d more greatly with the enlarged openings area.Yet if aperture area increases, the wind speed under the situation that attracts to clean will reduce, thereby reduces cleaning performance.

In the formation shown in Figure 40, when attracting cleaning, can adjust during with ventilation and inhale hole 10a～10d aperture area separately.

Among Figure 40, each inhales the standard-sized sheet mouth amplitude broad of hole 10a～10d, for example is 10mm.In attraction when cleaning of carrying out air cleaner, shown in Figure 40 (a), for example will inhale hole 10b and only open 3mm (also carrying out same operation when opening other suction hole 10a, 10c, 10d) by inhaling hole opening-closing plate 31b.The attraction air quantity can be dwindled like this, the attraction performance can be improved thereby wind speed is risen.

Next, all open when taking a breath will inhaling hole 10a～10d, be in full-gear with the width of 10mm, can significantly reduce the attraction wind speed by making each inhale hole 10a～10d.Like this, can significantly reduce windage, the output that does not need to improve suction device 6 just can access bigger ventilation air quantity.In addition, by reducing wind speed, the birdie that suction hole 10a～10d is produced also reduces, and is very desirable under the long-time ventilatory pattern of using, thereby has realized attracting the satisfactory to both parties of cleaning performance and scavenging performance.
