Summary of the invention

But, in above-mentioned patent documentation 1 described air conditioner, owing to just will wipe off attached to the dust on the filter by brush, so might be attached to again on the filter attached to the dust on the brush, in addition, also produced the problem that dust must have been abandoned when in the dust box, having accumulated dust.

On the other hand, in patent documentation 2 described filter for installations, owing to be not that brush will be removed attached to the dust on the filter, but the mode of removing by the attraction of air, so the possibility that does not have the damage filter or in clearing apparatus, accumulate dust.But, in this filter for installation, owing to making the suction inlet contact that is formed on the suction nozzle on filter surfaces, suck dust, if enlarge the scope that sucks dust so increase the area of suction inlet, then attraction dies down, the bigger attraction exhaust apparatus of air requirement for the reduction that prevents efficiency of dust collection, otherwise, improve attraction if reduce the area of suction inlet, then produce the time-consuming problem of the whole filter of cleaning.

So, in the present invention, purpose provide a kind of attraction exhaust apparatus that actual air volume is not bigger when adopting mode dust is removed by fluids such as air, can once carry out filter in a big way dedusting filter cleaning and be equipped with the conditioner of this clearing apparatus.

Relevant filter cleaning of the present invention, it is the filter cleaning that cleans the filter that airborne dust is removed, it is characterized in that, possess and have the air miscarriage life structure that filter can be produced air stream to the dedusting box in the slit of guided inside with in this dedusting box, in the dedusting box, produce air stream by above-mentioned air miscarriage life structure, will remove attached to the dust on the filter that directs into from above-mentioned slit in the dedusting box by above-mentioned air stream.

In addition, it is characterized in that, the dedusting box-like is become half point cut shape, the dedusting box that the half point that inside is formed with air flow circuit cuts shape is configured to each other, make its opening surface opposed, will be formed on gap between two boxes, the filter that airborne dust is removed in configuration as above-mentioned slit, ventilate in the dedusting box, will remove attached to the dust on the filter.

According to said structure, to remove attached to the dust on the filter owing to filter is housed in the space that surrounds by two boxes, in this limited space that ventilates, so do not need as attraction mouth mode in the past, to suck air from bigger suction inlet.Thereby as the mechanism that ventilates, the bigger structure of air requirement is not installed and can not maximized.

And then, can easily accelerate the flow velocity of air, can will blow expeditiously attached to the dust on the filter by this air stream and fly to remove.Here, half point cut shape the dedusting box if its opening surface to box to each other can be involutory the landform achievement passable, do not need to form identical shape.

As the air miscarriage life structure that in above-mentioned box, produces air and ventilate, can use and for example possess fan, air is taken into the structure that is taken into mouthful and discharges from fan the liberation port of air in this fan, be connected on the box by this being taken into mouth and liberation port, air circulation is passed in the box.

In addition, as other air miscarriage life structures, also can use air delivering mechanism that air is sent or the air that attracts air to attract mechanism.In the case, by on box, forming blow vent, air is circulated between blow vent and air delivering mechanism or air attraction mechanism.But,, preferably use air to attract mechanism from the viewpoint that dust can not disperse towards periphery from the gap of box and box.

The sectional area of air flow circuit is more little, can make the flow velocity of flow air in air flow circuit become big more.That is, as the dedusting box, even the area of the opening surface that half point cuts is identical, the structure that slenderly forms can make the flow velocity of flow air in air flow circuit become big more.In other words, if the sectional area of air flow circuit is less,, also less to the influence of the flow velocity of flow air in air flow circuit even then make the length of air flow circuit elongated.

Thereby, if dedusting box air flow circuit sectional area is less, form more longways even then pass across filter, also can easily produce flow velocity air stream faster.Particularly, if attract the attraction mechanism of air at the filter cross-directional one distolateral formation air entry of box, in another distolateral connection, then can in whole air flow circuit, produce flow velocity air stream faster, can will remove expeditiously thus attached to the dust on the filter in the air flow circuit.

Above-mentioned filter cleaning also can be set at the interval that filter can pass through with the slit or the gap of dedusting box, is provided with the travel mechanism that on the direction with respect to the length direction quadrature of dedusting box filter is relatively moved.Thus, can automatically clean whole filter.Travel mechanism both can make filter move with respect to fixing dedusting box, and the dedusting box is moved with respect to fixing filter.

The slit of dedusting box or the gap thickness than filter are big, more travel mechanism are successfully moved, and opposite, air flow in the box from the gap, and the flow velocity of the air that circulates in air flow circuit reduces.Otherwise if make the slit or the gap smaller of dedusting box, then when making travel mechanism's action, the open end contact of box makes attached to the dust on the filter and disperses towards periphery on the dust of filter surfaces.

So, in the present invention, as filter, use possesses a plurality of cross ribs, this cross rib that the surface is divided into the prominent shape of a plurality of partitions and vertically equally spaced disposes, forms the interval structure roughly the same with the width of dedusting box that makes between cross rib along filter, two boxes separate the gap arranged opposite that cross rib can pass through, by making travel mechanism's action that cross rib is positioned between the open end of two boxes, by two boxes and be clipped in the box body that cross rib between it forms tubular, will remove attached to the dust on the filter according to the partition that is housed in this box main body.

According to said structure, two boxes separate gap that cross rib can pass through and arranged opposite.That is, because box disposes under the state that leaves from filter surfaces, so even make travel mechanism's action, box can not contact on filter surfaces yet and dust is dispersed.

In addition, be positioned between the open end of two boxes, can enough cross ribs be stopped up by the slit or the gap of dedusting box by making cross rib.Like this, can and be clipped in the box body that cross rib between it forms tubular by two boxes, by make the attraction mechanism action under this state, the flow velocity that can not make the air that flows through air flow circuit reduces and cleans the partition that is surrounded by cross rib expeditiously.

If the cleaning of a partition finishes, then will attract mechanism to stop, as long as make filter move interval between cross rib, just adjacent partition can being accommodated in the box body, so, by the repetition aforesaid operations, can carry out the cleaning of filter according to partition.That is,, just can dust be dispersed and scavenge filter only by travel mechanism is moved off and on.

In addition, the another kind of structure of dispersing as the dust that prevents filter surfaces, filter part timesharing that also can be in cleaning enters into air flow circuit, travel mechanism is stopped, make dedusting box contact on filter and form air flow circuit, after the cleaning of filter part finishes, under the state that the dedusting box that is configured in the filter surfaces side that is attached with dust is left from filter, make travel mechanism's action, the filter of not cleaning is partly entered in the air flow circuit.

Particularly, for example if be configured such that on the basis that itself and the distance of filter can change at the dedusting box that the half point that will be configured in the filter surfaces side cuts shape, the active force by spring supports so that its always from filter leave, that the active force that overcomes spring by solenoid etc. during at filter cleaning is connected on the filter box is just passable.

In addition, also can on the surface of above-mentioned filter, longitudinally form the cross rib of the prominent shape of multiple row, above-mentioned dedusting box possesses in inside and is formed with the guiding walls that longitudinally forms on the box main body of air flow circuit and the vertical both ends at this box main body, form, make the longitudinal length of this guiding walls longer than the inside dimension of adjacent cross rib.

In said structure, on vertical both ends of the box main body of dedusting box, form guiding walls, form and make the length longitudinally of guiding walls longer, so in being guided the space that wall clips, always have cross rib than the inside dimension of adjacent cross rib.That is, can in the filter guide path that the slit that utilizes the dedusting box or gap are passed through as filter, this slit or gap be stopped up, come limit air turnover therefrom by cross rib with the prominent shape in cross section.More particularly, the dedusting box preferably is configured to, and makes the length at vertical both ends of box main body parallel with the length direction of cross rib.

Thus, can be suppressed at the reduction of the flow velocity of the air that circulates in the space that surrounds by the box main body of dedusting box, can will blow expeditiously attached to the dust on the filter that is contained in the dedusting box by this air stream and fly to remove.

As relevant filter cleaning of the present invention, also can constitute, except said structure, also possesses the cleaning brush that in the dedusting box, disposes along its length direction, make above-mentioned filter edge relatively mobile on one side with the direction of the length direction quadrature of dedusting box, make above-mentioned cleaning brush rotation on one side and the lip-deep dust attached to filter is broken away from, and remove from the dedusting box by the dust that above-mentioned air miscarriage life structure will float.

According to said structure, owing to make the filter edge relatively mobile on one side with respect to the direction of the length direction quadrature of dedusting box, make cleaning brush rotation driving on one side and the lip-deep dust attached to filter is broken away from, and will break away from the dust that floats by air miscarriage life structure and use the air that produces by air miscarriage life structure to flow to discharge to the outside, so also can it be floated and remove even adhere to lip-deep stubbornness dirty of filter from the dedusting box.

In addition,, also can possess the motor that rotation drives cleaning brush, make cleaning brush rotation driving and the lip-deep dust attached to filter is broken away from by motor as filter cleaning.

At this moment, the direction of rotation of cleaning brush can be set as follows.That is, the control motor is so that the direction of rotation of cleaning brush is a certain orientation.Such control is certain orientation owing to making the direction of rotation of motor, so become simple control.In addition, the direction of rotation of Ci Shi cleaning brush is preferably to rotating with respect to the opposed direction of past filter moving or that return.In addition, cleaning brush in coming and going of filter is moving the rotation drive ratio is returned when moving the time rotation driving easier will the removing of situation attached to the lip-deep dust of filter.

In addition, motor also can be set at, and the rotor-position when making it corresponding to its voltage starting decides the direction of rotation of motor, and the direction of rotation that makes cleaning brush is direction arbitrarily.

According to said structure and since the direction of rotation of motor during according to voltage starting rotor-position and forward or reverse, so direction of rotation changes with 1/2 probability.Therefore, compare to the situation that a direction is rotated, cleaning brush also only rotates to a direction with motor, dust ground, front and back on filter moves back and forth, and can prevent that on long terms dust from accumulating on the end of filter.

And then, also can be to the motor SECO, so that its direction of rotation is by positive rotation and contrary constituting of rotating.By said structure, the complexity though control can become slightly can prevent reliably that dust from accumulating on the end of filter.

Cleaning brush is not particularly limited its shape, but can illustration have the structure that is configured in the multi-disc elastic scraper on every side of rotating shaft with helical form.According to this structure, can not injure filter by the multi-disc elastic scraper, can reliably the dust on the filter surfaces be removed.

In addition, be formed on the extend axially setting of another distolateral elastic scraper of rotating shaft along rotating shaft, this extension portion of setting be configured in rotating shaft bearing portion around.According to this structure, the air that can prevent to contain the dust that is attracted invades the bearing portion from the end of scraper plate.

More than Shuo Ming filter cleaning is possessing suction inlet and blow-off outlet and is being clipped between it and in the conditioner of the filter that airborne dust is removed, conditioner is maximized and the additional filter cleaning function by carrying.Conditioner is not particularly limited so long as to possess the structure of filter that airborne dust is removed just passable, for example can enumerate air conditioner, humidifier, dehumidifier, air cleaning machine, warm-air drier etc.

In addition, carry under the situation in conditioner will possessing the filter cleaning that makes the travel mechanism that filter longitudinally moves back and forth, if filter in the past, then owing in order to prevent warpage or fluctuation, to keep conformality and need to a certain degree rigidity, so when filter moves, have to filter is exposed to outside the machine of conditioner, has produced the problem of infringement outward appearance.

So, in the present invention, possess a plurality of cross ribs that filter surfaces are divided into the prominent shape of a plurality of partitions, this cross rib is along vertically equally spaced configuration of filter, it is roughly the same with the width of box to form the interval that makes between this cross rib, two boxes separate the gap arranged opposite that cross rib can pass through, make travel mechanism's action and cross rib is positioned between the open end of two boxes, by two boxes and be clipped in the box body that cross rib between it forms tubular, the clearing apparatus of the structure that will will remove attached to the dust on the filter according to the partition that is housed in this box body carries in conditioner, filter can longitudinally be formed agley, be provided with the filter retainer mechanism that keeps making travel mechanism when action that the filter that is along the longitudinal movement is bent into U font roughly.

According to said structure, even reduce filter intensity and filter is longitudinally formed longitudinally flexiblely, also can keep sufficient conformality by a plurality of cross ribs that are formed on the filter, be housed in the conditioner so can make the filter bending that is along the longitudinal movement, play the effect that can not damage outward appearance.

More than, according to the present invention, owing to make and possess that have can be with the dedusting box of filter to the slit of guided inside, structure with the air miscarriage life structure that in this dedusting box, produces air stream, perhaps making the dedusting box that the half point that inside is formed with air flow circuit cuts shape is configured to make its opening surface opposed each other, the structure of configuration air cleaner in the gap between the dust box (slit), ventilate in the dedusting box and will remove attached to the dust on the above-mentioned filter, so the mechanism that actual air volume is bigger accelerates the speed that is passed to the air in the stream as the mechanism that ventilates, and can fly to remove with blowing expeditiously attached to the dust on the filter thus.

On blow-off outlet 3, swing be equipped with freely change along the vertical direction air flow towards shutter 9.In addition, this shutter 9 promptly moves when closing in the air-supply that makes warm and cold air, becomes like that as shown blow-off outlet 3 closing state.That is, shutter 9 also has the effect of the switching panel of blow-off outlet 3.

If carry out operation of air conditioner in the indoor set of said structure, then at first Air Blast fan 6 moves and sucks room airs from suction inlet 2, and this room air contacts with indoor heat converter 5 by filter 4.By being discharged into indoor from blow-off outlet 3 by indoor heat converter 5 systems room air warm or that refrigeration is conditioned.

The previous section of indoor set main body 1 opens and closes freely by front panel 7 and forms.The inboard of panel 7 is formed with filter guide 8 in front, as shown in Figure 3, opens by front panel 7 is mentioned upward, and the front end of filter guide 8 and its rotate in linkage and towards the place ahead, can insert filter 4 thus.If front panel 7 is closed, then the front end of filter guide 8 also rotates downwards in linkage, and as shown in Figure 2, filter 4 is set in the indoor set main body 1.

Suction inlet 2 be formed on main body 1 upper surface about on two positions, thereunder (near the downstream) as shown in Figure 4, disposes two corresponding to each suction inlet 2 along the left and right sides transversely arrangedly form the rectangular filter 4 of lengthwise.The horizontal length of filter 4 forms with each suction inlet 2 roughly the same.The length longitudinally of filter 4 forms longlyer than the longitudinal length of suction inlet 2, and these filter 4 bottoms are bent maintenance along filter guide 8 under with front panel 7 closing state.

Then, filter cleaning is described.The half point that the half point that filter cleaning possesses the surface of precoat filter 4 cuts the back side of dedusting box (being called table side box) 10 of shape and precoat filter 4 cuts the dedusting box (being called the dorsal part box) 11 of shape, as attraction fan 12 that attracts mechanism and the travel mechanism 43 that filter 4 is longitudinally moved back and forth.Table side box 10 forms half point with dorsal part box 11 and cuts shape, and as shown in Figure 5, both can be involutory each other with opening surface 10b and 11b.

Table side box 10 and dorsal part box 11 are as shown in Figure 4, clip than suction inlet 2 slightly on the front, promptly be formed with the top panel 13 of suction inlet 2 and front panel 7 boundary vicinity filter 4 parts and arranged opposite can not hinder from suction inlet 2 inhaled airs thus by filter 4.

Table side box 10 and dorsal part box 11 form elongated shape, making length direction be oriented to filter laterally is provided with, so that it crosses two filters 4 along left and right sides alignment arrangements, clip filter 4 devices spaced apart x and dispose so that both open ends 10a and 11a are opposed each other.

Particularly, as shown in Figure 5, at the length direction one distolateral blow vent 15 that is formed with of table side box 10 and dorsal part box 11, another distolateral between maintains under the state of x at interval and is remained on the pipe arrangement 14 by chimeric.Distolateral being connected to of another of pipe arrangement 14 attracts fan 12.

That is, two boxes 10 and 11 be formed in by mutual arranged opposite one distolaterally be formed with blow vent 15, at another distolateral box body 16 that attracts fan 12 that is connected with.And, become stream 17 by the space of its encirclement.Air flow circuit 17 has been made the blow vent 15 that makes box body 16 and has been attracted fan 12 to attract air to produce the structure of air stream for inlet, by entering the mouth to from this.

In the present invention, by in air flow circuit 17, produce air stream, the side of filter 4 from be housed in box body 16 is flow through air and will be removed attached to the dust on the filter 4 along the direction with filter 4 almost parallels.On box body 16, be formed with two slot-shaped gaps 18 (x at interval) along its length, filter 4 can be along the longitudinal movement in this gap 18.

In the present embodiment, box body 16 will be shown side box 10 and form as split with dorsal part box 11, with its arranged opposite, but two slits also can be set by the length direction along cylindrical body, will show the side box and the dorsal part box forms.

If the concrete structure to filter 4 describes, then as Figure 6 and Figure 7, filter 4 possesses web filter 19 and is located at plastic framework 31 around it for web filter 19 is reinforced, and framework 31 is made of vertical frame 32 and horizontal frame 33.And then filter 4 is reinforced by vertical rib 20 and cross rib 21.

Vertical rib 20 and cross rib 21 are synthetic resin system, equally spaced are formed with a plurality of respectively on the surface of web filter 19.Horizontal frame 33 and cross rib 21 form prominent shape for the warpage that prevents filter 4 or fluctuation, are heavy wall that with respect to this, vertical frame 32 and vertical rib 20 are than horizontal frame 33 and the formation of cross rib 21 thin-walled ground.Thus, filter 4 can be when keeping horizontal rigidity, in the vertical can be easily crooked.

On the outer edge of vertical frame 2, longitudinally be provided with tooth-strip part 22.Tooth-strip part 22 be with described later as travel mechanism pinion 28 engagements and mechanism that filter 4 is longitudinally moved back and forth has the shape that strip material is configured as waveform, its mountain portion brings into play function as tooth bar.In addition, tooth-strip part 22 separates formation with adjacent cross rib 21 as shown in Figure 8.By like this tooth-strip part 22 being formed waveform and separating, keep the bendability longitudinally of filter 4 with adjacent cross rib 21.

On the top of filter 4, as mentioned above, to open to be provided with and make the web filter 19 that passes through from suction inlet 2 inhaled airs, the filter bottom replaces web filter 19 and uses thin resin film-making 23, and the structure that air does not pass through is made in the filter bottom.In addition, resin film-making 23 similarly forms thin-walled with vertical rib 20, and it is whole and guarantee bendability longitudinally to spread all over filter 4 thus.

Make travel mechanism 43 that filter 4 longitudinally moves back and forth as Fig. 2 and shown in Figure 9, possess filter retainer mechanism 24 that keeps filter 4 and the driving mechanism 26 that filter 4 is moved by motor 25.Filter retainer mechanism 24 is made of a pair of guide path.Guide path forms roughly U font of cross section, the both ends, the left and right sides that can insert filter 4.By set up higher horizontal frame 33 of rigidity and cross rib 21 in the guide path of this pair of right and left, filter 4 can not be out of shape and be maintained in the guide path.

The cross sectional shape of filter retainer mechanism 24 is represented as blacking part and dash area in Fig. 2.Filter retainer mechanism 24 as shown in Figure 2, be provided with along suction inlet 2, when side gently tilts downwards on the front than suction inlet 2, between table side box 10 and dorsal part box 11, after generally perpendicularly descending along front panel 7 therefrom, U-shaped rotates and forms the U vee path V 24a that rises towards suction inlet to the inside.In addition, above-mentioned filter guide 8 constitutes the part of filter retainer mechanism under with front panel 7 closing state.

Driving mechanism 26 by motor 25, be attached at the driven wheel 27 on the motor 25 and constitute with the pinion 28 and the rubber rollers 29 of driven wheel 27 engagement.The not shown gear identical shaped with pinion is installed on the rotating shaft of rubber rollers 29, and pinion 28 rotates to identical direction with rubber rollers 29 thus.

Pinion 28 partly exposes near the filter retainer mechanism 24 the box body 16, disposes with the rear side engagement that is located at the tooth-strip part 22 on the filter 4.Rubber rollers 29 constitutes, and partly is exposed among the U vee path V 24a and disposes, and by rear side and the rotation that is connected to the filter 4 among the U vee path V 24a, can successfully carry out the moving of filter 4 of case of bending by its frictional force.

Driving mechanism 26 is respectively installed 1 group in each of the left and right sides of filter retainer mechanism guide path, and motor 25 as shown in Figure 9, two groups of driving mechanisms 26 are provided with 1, with about each driven wheel 27 of configuration be fixed on the same rotating shaft 30 that links with motor 25, about in the same manner rotation drive.

Under situation about filter 4 being arranged in the indoor set main body 1, make filter top for beginning, be inserted in the filter retainer mechanism 24 from filter guide 8, filter 4 is configured in the below of suction inlet 2.At this moment, two boxes 10 and 11 interval x make it bigger than thickness that the thickness with the thickness of cross rib 21 and filter adds up to by being set at, and bigger friction can not take place between filter 4 and two boxes 10 and 11, and filter 4 can successfully be set.In addition, filter 4 is the surface with the face that is formed with cross rib 21, this is faced up and is provided with.

Figure 10 is the general profile chart of the state of two boxes when being arranged on filter 4 in the indoor set main body 1 and filter.On filter 4, with and the roughly the same interval z of the width (the open end 10a of dedusting box and the distance between the 11a) of box 10 and 11 be formed with cross rib 21.Thus, cross rib 21 is arranged in be formed on the gap, two places 18 on the box body 16 and gap 18 is stopped up.Like this, can and be clipped in the box body 16 that cross rib 21 between it forms tubular very close to each other by table side box 10, dorsal part box 11.

In addition, in the present embodiment, at interval x is set at the thickness that adds up to than the thickness with the thickness of cross rib 21 and filter greatly, this is to consider the warpage etc. of filter and become smooth for the insertion that makes filter 4, attract fan 12 actions if make, then become negative pressure in the air flow circuit 17, the dedusting box is close to each other, so can access in fact and x and y roughly are set at the identical attraction of identical situation.

Then, the situation to the filter cleaning scavenge filter 4 by said structure describes.At first, carry out the running of air conditioner in the indoor set main body 1 if filter 4 is arranged on, then air is sucked from suction inlet 2, on the surface of airborne dust C attached to each partition 4a of the web filter of being divided by cross rib 2 19.

In indoor set main body 1, be provided with possess input circuit, the controlling organization of CPU, memory, output circuit, for example judge under the dirty situation in filter 4 surfaces in the situation that has reached given time the duration of runs of judging air conditioner or based on the testing result of dirty testing agencies such as optical sensor, control attracts the action of fan 12 and travel mechanism etc., carries out the cleaning of filter.

Particularly, at first, travel mechanism action, as shown in figure 10, make filter 4 be along the longitudinal movement between the cross rib 21 interval z and stop.At this moment, owing between table side box 10 and dorsal part box 11, be provided with the gap of x at interval, can not touch attached to filter 4 lip-deep dust C so show side box 10, and filter 4 is moved.Like this, the partition 4a adjacent to air flow circuit 17 enters into air flow circuit 17 originally, and then, can make cross rib 21 be arranged in the gap 18 of box body 16.

Then, attract fan 12 actions, attract air to attracting fan 12 from blow vent 15 as the inlet of air flow circuit 17.Thus, the air that the generation flow velocity is bigger in air flow circuit 17 flows, and will blow attached to the lip-deep dust C of partition 4a to fly and dedusting.The dust C that is removed from partition 4a can and attract to be provided with between the fan 12 dust bag (collection Zhu パ Star Network) at air flow circuit 17 and trap the there, or from attracting fan 12 to be vented to outdoor.After, by repeating above-mentioned action, can carry out the cleaning of filter 4 according to partition 4a.

When carrying out the cleaning of last partition 4a, filter 4 becomes maximum state that moves, and because filter 4 is bent and remains in the filter retainer mechanism 24, so filter 4 can not be exposed to the outside of indoor set, can not damage attractive in appearance.If the cleaning of last partition 4a finishes, then filter 4 is moved to original position by travel mechanism.

On the other hand, elastic scraper 41b is configured to, and it is flexibly contacted on the surface of filter 4, plays a role so that it will sweep attached to the lip-deep dust of filter 4 and it is floated.This elastic scraper 41b as shown in figure 16, distolateral from an end air entry 15 sides of rotating shaft 41a to another, along reel helical coil about two circles of axially forming of rotating shaft 41a, but on the end of attraction pipe arrangement 14 sides of this other end, elastic scraper 41b rotating shaft 41a axially on extend outside being set to distolateral, be set at make this extension be provided with the 41c of portion be positioned at rotating shaft 41a bearing portion 45 around, be set at and make the dust that is deposited in easily in the bearing portion 45 to attracting pipe arrangement 14 effluents to go out.

In addition, the suction inlet 2 that dedusting box 10,11 spreads all over the left and right sides forms more longways along left and right directions, but as shown in figure 16, also can be to set up reinforcement feature 48 in the centre position of box 10,11 and the structure reinforced.In the case, run on the reinforcement feature 48 and produce abnormal sound for the elastic scraper 41b that prevents cleaning brush 41 wipes, also can elastic scraper 41b axially on middle body cut away and form recess 49, can avoid reinforcement feature 48 when rotated.

In said structure, if carry out the running of air conditioner, then air is sucked by the suction inlet 2 from indoor unit main body 1, on the surface of airborne dust C attached to web filter 19.The controlling organization that is arranged in the indoor unit 1 is judged under the dirty situation in filter 4 surfaces in the situation that has reached given time the duration of runs of judging air conditioner or based on the testing result of dirty testing agencies such as optical sensor, control attracts the action of fan 12 and travel mechanism etc., carries out the cleaning of filter 4.

At first, travel mechanism 43 action, make filter 4 be along the longitudinal movement between the cross rib 21 interval z and stop.Under this state, make to attract fan 12 actions, attract air to attracting fan 12 from blow vent 15 as the inlet of stream 17.Simultaneously, make cleaning brush 41 rotation, will sweep attached to the lip-deep dust of filter 4 by elastic scraper 41b it is floated, by the air stream that attracts fan 12 dust is blown and fly and dedusting.

Like this, in the present embodiment, filter 4 is moved on one side along the guide path 18 of dedusting box 10,11, make cleaning brush 41 rotation drivings on one side and the lip-deep dust attached to filter 4 is broken away from, and will break away from the dust that floats by the air stream that produces by air miscarriage life structure and discharge to attraction fan 12 sides, remove so can make dirty also the floating forcibly of the lip-deep stubbornness that adheres to filter 4 from dedusting box 10,11.In addition, since will be formed on the extension of elastic scraper 41b of the attraction fan side of rotating shaft be provided with the 41c of portion be configured in rotating shaft 41a bearing portion 45 around, so the air that can prevent to contain the dust that is attracted invades the bearing portion 45 from the end of elastic scraper 41b.

In the above-described embodiment, filter being along the longitudinal movement, but replacing it, also can be the mode that dedusting box and cleaning brush are moved with respect to filter.

[the 4th embodiment]

Based on Figure 19 the 4th embodiment of the present invention is described.In the present embodiment, it is characterized in that controlling the rotation of the electro-motor of the cleaning brush rotation driving that makes in the 3rd embodiment, other structures and the 3rd embodiment are same.

Figure 19 (a), Figure 19 (b), Figure 19 (c) are the synoptic diagrams of filter cleaning of the control method of the different electro-motor of the difference of expression in the present embodiment.In Figure 19 (a), the control part 50 that electro-motor 47 is subjected to be made of microcomputer is controlled, so that the direction of rotation of cleaning brush 41 is a certain orientation.

Such control is certain orientation owing to making the direction of rotation of electro-motor 47, so become simple control.The direction of rotation of the cleaning brush 41 of this moment is driven to rotating with the opposed direction of the moving direction of filter 4 when past the moving of filter 4.For example, shown in Fig. 5 (a), when the A direction moved, the direction of rotation of cleaning brush 41 was driven to rotating with the opposed B direction of A direction, will remove attached to the lip-deep dust of filter 4 easily at filter 4.

In Figure 19 (b), electro-motor is set at the direction of rotation of the rotor-position decision motor when making it according to its voltage starting.Cleaning brush 41 is uncertain to which direction rotation.Usually, in electro-motor 47, the direction of rotation when starting in order to make is that certain orientation is provided with the lockable mechanism (diagram is omitted) of controlling the rotor-position when stopping.This lockable mechanism takes off the formations such as electromagnetic core that are located at freely on the rotor (diagram is omitted) by card, but this lockable mechanism is abandoned as known.So the stop position of rotor becomes uncertain, when restarting, according to the position of its rotor that stops, the direction of rotation of electro-motor 47 is a forward or reverse.

Thereby the cleaning brush 41 that is attached on the electro-motor 47 changes direction of rotation with 1/2 probability.If carry out the control of such electro-motor 47; direction of rotation at motor is a direction; and cleaning brush 41 is also under the situation of a direction rotation; dust might accumulate on the end of filter 4; but because direction of rotation is with 1/2 probability variation; so dust moves back and forth before and after becoming on filter, on long terms, can prevent that dust from accumulating on the end of filter 4.

In Figure 19 (c), carry out SECO by 50 pairs of electro-motors of control part 47, so that its direction of rotation constituting by positive rotation and contrary rotation.In control part 50, for example clean running and in making 10 times of the opposite or cleaning running of direction of rotation for 1 time, make direction of rotation become rightabout control 1 time.

In said structure, the SECO by electro-motor 47 makes control become complicated slightly, but dust can always not accumulate on the end of filter 4 for certain situation as direction of rotation, can reliably the dust on the filter 4 be removed.

In addition, the suction inlet 2 that dedusting box 10,11 spreads all over the left and right sides forms more longways along left and right directions, but also can be to set up reinforcement feature 48 in the centre position of box 10,11 as shown in Figure 16 and the structure reinforced.In the case, run on the reinforcement feature 48 and produce abnormal sound for the elastic scraper 41b that prevents cleaning brush 41 wipes, also can elastic scraper 41b axially on middle body cut away and form recess 49, can avoid reinforcement feature 48 when rotated.
