As depicted in figs. 1 and 2, be formed with suction inlet 111 and blow-off outlet 12 respectively in the upper and lower of the indoor set main body 1 of air conditioner.In the inside of indoor set main body 1, be formed with ventilating path 12 from suction inlet 111 to blow-off outlet.In this ventilating path, be upstream side with suction inlet 111 sides, dispose filter 13, indoor heat converter 14, Air Blast fan 15 successively.And, in indoor set main body 1, be provided with the filter cleaning 20 of scavenge filter 13.

On blow-off outlet 12, swing be equipped with freely change along the vertical direction air flow towards shutter 18.In addition, shutter 18 promptly moves when the air-supply that makes the cooling/heating air-flow is closed, and as shown in Figure 2, makes blow-off outlet 12 become closing state.That is, shutter 18 also plays the effect of the switching panel of blow-off outlet 12.

If carry out air mediation running in the indoor set main body 1 that constitutes as described above, then at first Air Blast fan 15 moves and sucks room airs from suction inlet 111, and this room air touches indoor heat converter 14 by filter 13.Be discharged into indoor by being heated by indoor heat converter 14 or cooling off the room air that is in harmonious proportion from blow-off outlet 12.

The previous section of indoor set main body 1 is opened and closed by front panel 16 and forms freely.The inboard of panel 16 is formed with filter guidance part 17 in front.As shown in Figure 3, by with front panel 16 upward pull-up open, with its interlock, the front end of filter guidance part 17 rotates and towards the place ahead.Thus, can insert filter 13.If front panel 16 is closed, then the front end of filter guidance part 17 also rotates downwards in linkage, as shown in Figure 2, filter 13 is set in the indoor set main body 1.

As shown in Figure 1, suction inlet 111 be formed on indoor set main body 1 upper surface about on two positions.Thereunder (near the downstream), as shown in Figure 4, corresponding to each suction inlet 111, the left and right sides is transversely arranged and dispose two and form the square filter of lengthwise 13.The horizontal length of filter 13 forms with each suction inlet 111 roughly the same.The length longitudinally of filter 13 forms longer than the longitudinal length of suction inlet 111.The bottom of filter 13 is bent maintenance along filter guidance part 17 under with front panel 16 closing state.

Then, filter cleaning is described.The dust that filter cleaning 20 possesses the surface of precoat filter 13 remove the dust at the back side of box (table side box) 21, precoat filter 13 remove box (dorsal part box) 22, as attraction fan 23 that attracts mechanism and the travel mechanism that filter 13 is longitudinally moved back and forth.Table side box 21 and dorsal part box 22 form two fens shapes, and as shown in Figure 5, both can dock each other by

opening surface

21b and 22b.

Table side box 21 and dorsal part box 22 clip to be positioned at than suction inlet 111 and slightly on the front, promptly are formed with the part of filter 13 of boundary vicinity of the top panel 11 of suction inlet 111 and front panel 16 and arranged opposite as shown in Figure 1 and Figure 4.Thus, table side box 21 and dorsal part box 22 can not hinder from suction inlet 111 inhaled airs by filter 13.

Table side box 21 and dorsal part box 22 form elongated shape, make length direction be oriented in laterally being provided with of filter 13, so that it crosses two filters 13 of left and right sides alignment arrangements, as Figure 10 and clip filter 13 as shown in Figure 11, as shown in Figure 5, devices spaced apart x and disposing so that both

open ends

21a and 22a are opposed each other.

Particularly, as shown in Figure 4,, keeping chimeric remaining on the pipe arrangement 25 under the state of x at interval at another distolateral between at a distolateral blow vent 24 that is formed with of the length direction of table side box 21 and dorsal part box 22.Distolateral being connected of another of pipe arrangement 25 attracts on the fan 23.

That is, two

boxes

21 and 22 are by mutual arranged opposite, are formed in a distolateral formation blow vent 24, attract the box body of fan 23 in another distolateral connection.And, with the space of this encirclement as stream 26.Stream 26 is as inlet, attract fan 23 to produce the structure that air flows by air is attracted to from this inlet with the blow vent 24 of box body.

In one embodiment of the present invention, by in stream 26, producing air stream, being flowed with filter 13 almost parallel directions in the edge, side of the filter 13 of air from be housed in box body, will remove attached to the dust on the filter 13.As shown in Figure 5, on box body, be formed with two slot-shaped gaps 27 (x at interval) along its length.Configuration filter 13 is so that it can be along the longitudinal movement in gap 27.

In the present embodiment, box body will show side box 21 and dorsal part box 22 forms split, with its arranged opposite, but also can be by two slits being set on the length direction of cylindrical body, will showing the side box and the dorsal part box forms.

If the concrete structure to filter 13 describes, then as shown in Figure 6 and Figure 7, filter 13 possesses web filter 131 and is located at plastic framework 132 around it for reinforcing network filter 131.Framework 132 is made of vertical frame 133 and horizontal frame 134.And then filter 13 is reinforced by vertical rib 135 and cross rib 136.

Vertical rib 135 and cross rib 136 are synthetic resin system, and be a plurality of uniformly-spaced to be formed with on the surface of web filter 131 respectively.Horizontal frame 134 and cross rib 136 for the warpage that prevents filter 13 or ripple and form convex, be heavy wall, with respect to this, vertical frame 133 and vertical rib 135 form than horizontal frame 134 and cross rib 136 thin-walleds.Thus, filter 13 can be easily crooked in the vertical when keeping horizontal rigidity.

On the outer edge of vertical frame 133, be vertically arranged with tooth-strip part 137.Tooth-strip part 137 be with described later as travel mechanism pinion 35 engagements and parts that filter 13 is longitudinally moved back and forth have the shape that banded material is configured as waveform, its mountain portion brings into play function as tooth bar.In addition, tooth-strip part 137 separates and forms from adjacent cross rib 136 as shown in Figure 8.Like this, by tooth-strip part 137 being formed waveform and separating, keep the bendability longitudinally of filter 13 from adjacent cross rib 136.

On the top of filter 13, as mentioned above, pass through in order to make from suction inlet 111 inhaled airs, be provided with web filter 131 and open, in the bottom of filter 13, use thin resin film-making 138 to replace web filter 131, the intransitable structure of air is made in the bottom of filter 13.In addition, by resin film-making 138 and vertical rib 135 are similarly formed thin-walled, can guarantee the bendability longitudinally of filter 13 integral body.

Travel mechanism such as Fig. 2 and shown in Figure 9 that filter 13 is longitudinally moved back and forth possess filter retainer mechanism 31 that keeps filter 13 and the drive division 30 that filter 13 is moved by motor 32.Filter retainer mechanism 31 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 of filter 13 can be inserted.By set up higher horizontal frame 134 of rigidity and cross rib 136 on the guide path of this pair of right and left, filter 13 can not be out of shape and be maintained in the guide path.

The cross sectional shape of filter retainer mechanism 31 is expressed as blacking part and grid part in Fig. 2.Filter retainer mechanism 31 as shown in Figure 2, be provided with along suction inlet 111, be formed with on one side than suction inlet 111 on the front side gently tilt downwards by between table side box 21 and the dorsal part box 22, therefrom generally perpendicularly descend along front panel 16 after, U-shaped rotates and towards the U vee path V 31a of suction inlet 111 risings to the inside.In addition, above-mentioned filter guidance part 17 constitutes the part of filter retainer mechanism under with front panel 16 closing state.

Drive division 30 by motor 32, be attached at the driven wheel 34 on the motor 32, pinion 35 and the rubber rollers 36 that is engaged on the driven wheel 34 constitutes.The not shown gear identical shaped with pinion is installed on the rotating shaft of rubber rollers 36, and thus, pinion 35 rotates to equidirectional with rubber rollers 36.

Pinion 35 partly exposes near the filter retainer mechanism 31 of box body, is configured to, and makes itself and the rear side engagement that is located at the tooth-strip part 137 on the filter 13.Rubber rollers 36 is configured to, and it partly is exposed among the U vee path V 31a, constitutes, by rotating, can successfully carry out by its frictional force the moving of filter 13 of case of bending on the rear side that is connected to the filter 13 among the U vee path V 31a.

Drive division 30 respectively is equipped with 1 group in the guide path of the left and right sides of filter retainer mechanism 31, and motor 32 as shown in Figure 9, be provided with 1 with respect to two groups of drive divisions 30, about each driven wheel 34 of setting be fixed on the identical rotating shaft 33 that is linked on the motor 32, about in the same manner rotation drive.

Under situation about filter 13 being arranged in the indoor set main body 1, the top of filter 13 as initial, is inserted in the filter retainer mechanism 31 from filter guidance part 17, filter 13 is configured in the below of suction inlet 111.At this moment, as Fig. 5 and shown in Figure 10, two

boxes

21 and 22 interval x are big slightly by the thickness y that is set at after it is added up to than the thickness with the thickness of cross rib 136 and filter 13, can not produce bigger friction between filter 13 and two

boxes

21 and 22, and filter 13 can successfully be set.In addition, filter 13 will be formed with the face (being the face of representing with arrow Q) of cross rib 136 as the surface in Fig. 7, this face is provided with for last, but also can be the structure that the table back of the body is provided with on the contrary.

Figure 10 is the general profile chart that is illustrated in the state of two boxes when being provided with filter 13 in the indoor set main body 1 and filter.On filter 13, with and the roughly the same interval z of the width of box 21 and 22 (dust remove the open end 21a of box and the distance between the 22a) be formed with cross rib 136.Thus, cross rib 136 can be positioned in the gap 27 that is formed at two places on the box body and gap 27 is stopped up.Like this, can and be clipped in the box body that cross rib 136 between it forms tubular very close to each other by table side box 21, dorsal part box 22.

In addition, in the present embodiment, x is set at interval, thickness y after it is added up to than the thickness with the thickness of cross rib 136 and filter 13 is big slightly, this is to consider the warpage etc. of filter and for the insertion that makes filter 13 becomes smoothly, attract fan 23 actions if make, and then becomes negative pressure in the stream 26, dust is removed box and is close to each other, so in fact can access and x and y are set at attraction identical under the roughly the same situation.

Then, the action by the filter cleaning scavenge filter 13 that constitutes is as described above described.

At first, carry out the running of air conditioner in the indoor set main body 1 if filter 13 is arranged on, then suck air from suction inlet 111, as shown in figure 10, on the surface of airborne dust 13b attached to each partition 13a of the web filter of dividing by cross rib 136 131.

In indoor set main body 1, be provided with possess input circuit, the control part of CPU, memory, output circuit, as described later, corresponding to the set moment, control attracts the action of fan 23 and travel mechanism etc., carries out the cleaning of filter 13.

Particularly, at first, travel mechanism action, as representing with arrow R among Figure 10, make filter 13 be along the longitudinal movement 136 of cross ribs interval z and stop.At this moment, owing between table side box 21 and dorsal part box 22, be provided with the gap of x at interval, filter 13 is moved so table side box 21 is not touched attached to the lip-deep dust 13b of filter 13.Like this, can make originally partition 13a enter into stream 26, cross rib 13 is positioned in the gap 27 of box body again adjacent to stream 26.

Then, attract fan 23 actions, air is attracted to the position that attracts fan 23 from the blow vent 24 as the inlet of stream 26.Thus, the air that the generation flow velocity is bigger in stream 26 flows, and will blow attached to the lip-deep dust 13b of partition 13a to fly and dedusting.In the case, also can in stream 26, drive rotating brush (not shown).Between stream 26 and attraction fan 23 dust bag is set, the dust 13b that will be removed from partition 13a traps here, perhaps can be discharged to outdoor from attracting fan 23 along the direction of representing with arrow P among Fig. 4.After, by repeating above-mentioned action, can carry out the cleaning of filter 13 to each partition 13a.

When carrying out the cleaning of last partition 13a, filter 13 becomes maximum state that moves, but because filter 13 is bent and remains in the filter retainer mechanism 31, so filter 13 can not be exposed to the outside of indoor set, can not damage aesthetic feeling.If the cleaning of last partition 13a finishes, then filter 13 is moved to original position in the effect of travel mechanism.

In the present embodiment, one of the length direction of the box body that is made of table side box 21 and dorsal part box 22 distolaterally is whole unlimited blow vent 24, but also can reduce the aperture area of blow vent 24.In the case, can accelerate to flow through the flow velocity of the air of stream 26, the lip-deep dust attached to filter can be removed expeditiously.

And then the lip-deep cross rib 136 that is formed on filter 13 to be forming with the roughly the same interval z of the width of two

boxes

21 and 22, but also can form with the interval that z at interval etc. is cut apart.For example, as shown in figure 11, can form cross rib 136 with the interval of z/2.In the case, both can make filter 13 each z at interval that move, also can move z/2 at interval at every turn.

Then, the running of filter cleaning to action as described above describes constantly.

Figure 12 is the block diagram of control of the running of expression filter cleaning.Figure 13 is the flow chart that is illustrated in the sequence of operation of the filter cleaning that moment that the running of air conditioner stops carries out.Figure 14 is the flow chart of the sequence of operation of the filter cleaning that carries out during the running that is illustrated in air conditioner stops.

Figure 15 is the figure of structure that represents the remote controller of air conditioner as one embodiment of the present invention.Figure 16 is the figure of the interior part-structure of the remote controller of expression Figure 15.In remote controller shown in Figure 15 40, cover 41 and move by making, as shown in figure 16, can see the running that is used for setting filter cleaning or be used for carrying out " cleaning " button 42 of the running of filter cleaning.

At first, the action button of remote controller shown in Figure 15 40 is pressed, with the set operation mode running air conditioner of refrigeration etc.Thus, as shown in figure 13, in step S1, air conditioner is the state in the running.

Then, by the action button of remote controller 40 is pressed, perhaps by timer etc., in step S2, the running of air conditioner stops.

At this moment, in step 3, indoor set control part 10 judges whether to have preestablished by " cleaning " button 42 of pressing remote controller shown in Figure 16 40 to carry out the running of filter cleaning, i.e. " cleaning " running in advance.Under the situation that does not preestablish the running of carrying out filter cleaning, former state finishes the running of air conditioner.

Under the situation that has preestablished the running of carrying out filter cleaning, in step S4, indoor set control part 10 judges whether it is by timer the running of air conditioner to be stopped.

Not by timer air conditioner to be stopped but common passing through pressed under the situation that the running of the air conditioner that the action button of remote controller 40 carries out stops, in step S5,10 pairs of filter cleanings 20 of indoor set control part transmit control signal so that it carries out " filter cleaning running A ".The content of the concrete filter cleaning of " filter cleaning running A " for example is once back and forth to make filter 13 move to the action of another end from an end and drive to attract fan 23.At this moment, if in filter cleaning 20, possess rotating brush, then also drive rotating brush.

Under the situation that air conditioner is stopped, in step S6,10 pairs of filter cleanings 20 of indoor set control part transmit control signal so that it carries out " filter cleaning running B ".The content of the concrete filter cleaning of " filter cleaning running B " for example is once back and forth to make filter 13 move to the action of another end from an end, still attract fan 23 or do not drive attraction fan 23 relatively to drive than " filter is cleared away running A " low voltage.At this moment, if in filter cleaning 20, possess rotating brush, then drive rotating brush or do not drive rotating brush.

Like this, under the situation that air conditioner is stopped, attract fan 23 or do not drive to attract fan 23 or do not drive rotating brush relatively to drive than " filter cleaning running A " low voltage, be because, the user makes the situation of air conditioner running more at h.d. by timer, considers that the running sound that is accompanied by the filter cleaning when by timer air conditioner being stopped to bring sense of discomfort to carry out the appropriate filters cleaning can for the user of the state that is in sleep etc.In addition, preferably make the time weak point of the time ratio " filter cleaning running A " of " filter cleaning running B ".

In step S5 or step S6, if filter cleaning running finishes, then air conditioner becomes the running halted state.

Like this, as shown in figure 14, in step S7, when state that air conditioner stops, in step S8, by " cleaning " button 42 of remote controller shown in Figure 16 40 is pressed down the running of carrying out filter cleaning.At this moment, in step S9,10 pairs of filter cleanings 20 of indoor set control part transmit control signal so that it carries out " filter cleaning running C ".The content of the concrete filter cleaning of " filter cleaning running C " for example be carry out back and forth making for three times filter 13 move to from an end another end action, but relatively filter 13 is moved than " filter cleaning running A " low speed.Therefore, the time of the time ratio of " filter cleaning running C " " filter cleaning running A " is long.At this moment, if in filter cleaning 20, possess rotating brush, then also drive rotating brush.

In addition, carrying out behind the filter cleaning according to above-mentioned any filter cleaning running, in the moment that the set time stops with the running of interior air conditioner, indoor set control part 10 does not transmit control signal to filter cleaning 20 so that it carries out filter cleaning running.The set time in the case for example is set at 24 hours, is stored in indoor set control part 10 in the nonvolatile memory (EEPROM), can utilize remote controller 40 suitably to change.

In addition, the reciprocal time that moves of the filter 13 of " filter cleaning running C " is set at 3 times in the above-described embodiment, but can in indoor set control part 10, be stored in the nonvolatile memory (EEPROM), can utilize remote controller 40 suitably to change.

" stop " button if press the running of remote controller 40 in above-mentioned any filter cleaning running, then 10 pairs of filter cleanings 20 of indoor set control part transmit control signal so that it forces to finish filter cleaning running.In addition, if press " cleaning " button 42 of remote controller 40 in " filter cleaning running C ", then 10 pairs of filter cleanings 20 of indoor set control part transmit control signal so that it forces to finish filter cleaning running.

More than, indoor set control part 10 is controlled, so that make filter cleaning 20 runnings with any of different a plurality of operation modes respectively, so can make filter cleaning 20 runnings with different operation modes corresponding to the various moment in the operational situation of air conditioner corresponding to the multiple moment.Therefore, can corresponding to the various moment in the operational situation of air conditioner with different cleaning content scavenge filters.

In the above-described embodiment, the multiple moment is that running beyond timer that the timer of air conditioner cuts out the running that brings (step S6), air conditioner when finishing cuts out is during the running of (step S5) and air conditioner stops when finishing (step S9).

By like this, can make the cleaning content " filter cleaning running A " of the filter that when the timer of air conditioner cuts out the content " filter cleaning running B " of the cleaning of the filter that carries out when the running that brings finishes and running beyond closing at timer finishes, carries out different, and also difference of the cleaning content " filter cleaning running C " that also can make the filter that in the running of air conditioner stops, carrying out.Thus, can carry out the cleaning of filter corresponding to the operational situation of air conditioner with suitable cleaning content.

In addition, in the above-described embodiment, at a plurality of operation modes, promptly among " filter cleaning running A ", " filter cleaning running B ", " the filter cleaning running C ", the difference duration of runs of filter cleaning.

By like this, can corresponding to various moment of the operational situation of air conditioner with different cleaning time scavenge filters.Particularly, in the running of air conditioner stops, by prolonging the cleaning time of " filter cleaning running C ", carefully scavenge filter.In addition, when the timer of air conditioner cuts out the running end that brings, by shortening the cleaning time of " filter cleaning running B ", bring sense of discomfort the running sound that is accompanied by filter cleaning when by timer air conditioner being stopped can not for be in the user of the state of sleep etc., and, even when timer cuts out the running end of the air conditioner that brings, also can carry out suitable cleaning.

And then, in the above-described embodiment, a plurality of operation modes, promptly, the running sound of " filter cleaning running B " is different with respect to " filter cleaning running A " and " filter cleaning turn round C ".

By like this, can corresponding to various moment of the operational situation of air conditioner with different running sound scavenge filters, so in " filter cleaning running B ", can consider especially to the user and bring the noise etc. of sense of discomfort and carry out the appropriate filters cleaning.

In addition, in the above-described embodiment, the separation type air conditioner is illustrated, but also can be one-piece type air conditioner.

More than disclosed embodiment aspect all, all should think illustration rather than restriction.Scope of the present invention is not by above embodiment but represented by claims, comprises the meaning that is equal to claims and all corrections and the distortion in the scope.
