Above-mentioned introducing pipeline (86) is connected with the upper surface of baffle plate box (81), and is communicated with Room the 1st (81a).As shown in figure 10, introduce pipeline (86) and extend, and connect demarcation strip (25) from baffle plate box (81) along vertical direction.Introduce pipeline (86) and comprise that the cross section is circular one a side pipe road (86a), upstream and a dirty side pipe road (86b), these two parts are linked along above-below direction by dogbolt (28a).The area of section (flow path area) in one side pipe road (86a), upstream is bigger than the area of section (flow path area) in a dirty side pipe road (86b).The lower end in a dirty side pipe road (86b) (lower end among Figure 10) is connected with baffle plate box (81).The upper end (upside among Figure 10) in one side pipe road (86a), upstream is across the horizontally extending parts butt of seal member (86e) with horn mouth (24).On the horizontally extending parts of this horn mouth (24), form intake (86d) as through hole.By this intake (86d), one side pipe road (86), upstream is communicated with the space of indoor fan (21) one sides.That is, this introducing pipeline (86) is used for the blow out air of indoor fan (21) is introduced in the baffle plate box (81).

In addition, the linking portion in the one side pipe road (86a), upstream of above-mentioned introducing pipeline (86) and a dirty side pipe road (86b) is positioned at the breakthrough part of demarcation strip (25).Specifically, with the mode that the upper end flange in the base plate in one side pipe road (86a), upstream and a dirty side pipe road (86b) is clamped the through hole periphery of demarcation strip (25), two pipelines (86a, 86b) are bonded.To do as a whole be that the mode that the center rotates constitutes with the axle center of introducing pipeline (86) to the part of this linking portion and seal member (86e) according to introducing pipeline (86) and baffle plate box (81) and dust hold-up vessel (60).

The end that the conduct of above-mentioned attraction pipeline (87) flows into a side is connected with the lower surface of baffle plate box (81), and is communicated with Room the 2nd (81b).The conduct of attraction pipeline (87) is flowed out the other end of a side and is connected with a dust catcher insertion mouthful (not shown) of going up formation at decorative panel (11).The opening that the flexible pipe that this dust catcher insertion mouth is the insertion dust catcher etc. is used to attract.In addition, attraction pipeline (87) adopts flexible pipe to constitute.

As depicted in figs. 1 and 2, the 2nd end (67) of the reservoir (62) in an end of above-mentioned conveyance conduit (88) and the dust hold-up vessel (60) is connected, and the other end is connected with dust catch described later (90).This conveyance conduit (88) adopts flexible pipe to constitute.

In above-mentioned dust transport mechanism (80), under the situation of the common running of carrying out cooling/heating, the baffle plate (82) of baffle plate box (81) is closed (with reference to Figure 11 (A)).So the blow out air of indoor fan (21) can not be introduced into baffle plate box (81).In addition, in dust transport mechanism (80), with the dust transport in the dust hold-up vessel (60) to the situation of dust catch (90), the baffle plate (82) of baffle plate box (81) is opened (with reference to Figure 11 (B)).So the blow out air of indoor fan (21) is introduced into dust hold-up vessel (60) by introducing pipeline (86) and baffle plate box (81).As a result, dust in the dust hold-up vessel (60) and air are together carried to dust catch (90) by conveyance conduit (88).That is, the dust of dust hold-up vessel (60) is discharged from.

And in above-mentioned dust transport mechanism (80), under the situation that the dust of dust catch (90) is discharged outside casing (10), the baffle plate (82) of baffle plate box (81) also is closed (with reference to Figure 11 (C)).In the case, attract mouth to be attracted, so the dust in the dust catch (90) is attracted by dust catcher by conveyance conduit (88), baffle plate box (81) and attraction pipeline (87) by dust catcher from dust catcher.That is, this dust transport mechanism (80) utilizes the blow out air of indoor fan (21), with the dust transport of dust hold-up vessel (60) to assigned position.

Above-mentioned dust catch (90) as shown in Figures 1 and 2, as mentioned above, the dust in the dust hold-up vessel (60) is transferred then and is stored in wherein.Dust catch (90) roughly forms the rectangular shape of slightly elongated, is configured in the below of demarcation strip (25) equally with dust hold-up vessel (60).Dust catch (90) is according to the end limit configuration of the mode that does not cover air cleaner (30) on the plane along demarcation strip (25).Like this, the end with the opposite side of a side that connects conveyance conduit (88) from the dust catch (90) that sucks the air that grid (12) is inhaled into becomes exhaust outlet (91).The part of this exhaust outlet (91) connects casing (10) and is communicated with indoor then.In addition, the breakthrough part at this exhaust outlet (91) is arranged with seal member (93).

Overlook above-mentioned dust catch (90), specific area is little mutually with other parts for the part of exhaust outlet (91).In addition, the side plate of air cleaner (30) one sides of dust catch (90) is circular-arc with the corresponding formation of the periphery of air cleaner (30).And, in dust catch (90), near exhaust outlet (91), be provided with filter (92).In dust catch (90), under the situation that dust is transferred from dust hold-up vessel (60), inner air is discharged from from exhaust outlet (91).At this moment, owing to be provided with filter (92), therefore, the dust that is transferred can not flow out from exhaust outlet (91).In addition, under the situation that the attraction dust because of dust catcher is discharged from from dust catch (90), room air flows in the dust catch (90) by exhaust outlet (91).At this moment, the dust in the leaked-in air is filtered device (92) capture.So, because of exhaust outlet (91) give the gas exhaust, the pressure balance in the dust catch (90) becomes suitable, therefore, correctly carries out carrying towards dust catch (90) the conveying action and the discharging operation of dust.

The running action

Below, with reference to Figure 12～Figure 14, the action of the running in the above-mentioned indoor units (1) is described.Indoor units (1) can be switched the common running of carrying out cooling/heating and the filter cleaning running that air cleaner (30) is cleaned.

(running usually)

Shown in Figure 12 (A), in common running, air cleaner (30) with brush (51b) state of contact of rotating brush (51) under be stopped.In addition, the baffle plate (82) of baffle plate box (81) is closed (state of Figure 11 (A)).

Under this state, indoor fan (21) is driven.So in indoor units (1), the room air that sucks from suction inlet (13) flows into the horn mouth (24) by air cleaner (30) back.When air passed through air cleaner (30), airborne dust was caught by the mesh parts (37) of air cleaner (30).The air that flows into horn mouth (24) is blown out by indoor fan (21).The cold-producing medium of this blow out air and indoor heat converter (22) carries out heat exchange and after being cooled or being heated, is supplied to indoor from each blow-off outlet (14).Carry out indoor refrigeration like this or make warm.

So in turning round usually, because the baffle plate (82) of baffle plate box (81) is closed, therefore, the blow out air of indoor fan (21) can not be introduced in the dust hold-up vessel (60) by baffle plate box (81).That is, introducing air to dust hold-up vessel (60) is under an embargo.

(filter cleaning running)

In the filter cleaning running, compressor stops in refrigerant loop, and cold-producing medium becomes the state that does not circulate.In this filter cleaning running, can switch " dedusting action ", " brush cleaning action ", " dust transport action " and " dust discharging operation ".

" dedusting action " is to utilize rotating brush (51) to remove the action of the dust of air cleaner (30)." brush cleans action " is to utilize cleaning to remove the action of the dust that is rotated brush (51) seizure with brush (52)." dust transport action " is the action of carrying dust from dust hold-up vessel (60) to dust catch (90)." dust discharging operation " is the action of discharging dust from dust catch (90) outside casing (10).

In the present embodiment, interactive mode is carried out " dedusting action " and " brush cleaning action ".At first, in " dedusting action ", indoor fan (21) becomes halted state.Then, shown in Figure 12 (B), utilize filter driver part (40), air cleaner (30) with rotating brush (51) state of contact under be rotated counterclockwise.That is, shown in Figure 13 (A), air cleaner (30) according to the bristle of the brush (51b) of rotating brush (51) towards (towards left bank) over against mode move.In addition, at this moment, rotating brush (51) continues to keep halted state.

So the dust of air cleaner (30) is rotated the brush (51b) of brush (51) and catches.Herein and since the bristle of brush (51b) towards with the direction of rotation (moving direction) of air cleaner (30) over against and tilt, therefore, the dust of air cleaner (30) is easy to be fallen by brush (51b) brush.So the efficiency of dust collection of rotating brush (51) improves.Then, if the action of the control lever (44a) of the limit switch (44) of filter driver part (40), so, filter drive motors (41) will stop, and air cleaner (30) stops thereupon.That is, stop after the angle of air cleaner (30) rotation regulation.Like this, in air cleaner (30), the dust in the zone that the brush (51b) of rotating brush (51) passes through is removed.If air cleaner (30) stops, so, switching to " brush cleaning action " from " dedusting action ".

But, after air cleaner (30) stops, shown in Figure 13 (B), in rotating brush (51), the right side (that is moving direction one side of air cleaner (30)) of dust deflection brush (51b).This is because the dust that is fallen by brush (51b) brush departs from along with moving of air cleaner (30).If this situation continued, so, the caking of dust will increase, and might finally fall into indoor etc.

Therefore, in " brush cleaning action ", shown in Figure 12 (C), at first, air cleaner (30) is filtered device driver part (40) and returns the rotation predetermined angular clockwise.That is, also shown in Figure 14 (A), air cleaner (30) opposite direction along the time with " dedusting action ", promptly with the bristle of the brush (51b) of rotating brush (51) towards identical direction rotation.In the present embodiment, make air cleaner (30) rotate the predetermined angular of the distance of the width that moves the brush (51b) that is equivalent to rotating brush (51).In addition, in this action, indoor fan (21) and rotating brush (51) keep halted state.

So shown in Figure 14 (A), the dust on the right side of deflection brush (51b) is even by air cleaner (30) in rotating brush (51).That is, dust is equably attached on the whole brush (51b).Like this, the dust of air cleaner (30) is caught exactly by brush (51b).As a result, the caking that can prevent dust conscientiously falls into indoor etc.

Then, in " brush cleaning action ", under the state that indoor fan (21) and air cleaner (30) stop, rotating brush (51) in Figure 14 towards the left side (counterclockwise) rotate.At this moment, rotating brush (51) rotates under the state of having caught dust on the brush (51b).In addition, rotating brush (51) and cleaning are in contact with one another with the brush (51b, 52b) of brush (52), simultaneously rotating brush (51) rotation (with reference to Figure 14 (B)).Will stop after the anglec of rotation of rotating brush (51) rotation regulation.

Then, rotating brush (51) is according to rotating with above-mentioned opposite direction (that is the right side among Figure 14 (clockwise)).So, be rotated the brush (52b) that dust that the brush (51b) of brush (51) catches cleaned with brushing (52) and remove (with reference to Figure 14 (C)).Cleaning with the bristle of brush (52b) of the brush (52b) of brush (52) towards down, that is, and bristle towards with the direction of rotation of rotating brush (51) over against direction tilt, therefore, dust is easy to go up by brush from the brush of rotating brush (51) (51b).And by the spinning movement of returning of the air cleaner (30) shown in Figure 14 (A), dust is equably on the whole brush (51b) attached to rotating brush (15), therefore, utilizes cleaning can be more prone to brush (52) and accurate scrubbing brush falls this dust.

In addition, (51b, 52b) is in contact with one another by two brushes, and like this, cleaning just is pushed to the rear with the body (52a) of brush (52), and still, body (52a) is suppressed towards rotating brush (51) one sides by spring portion (52c).Like this, brush (51b, 52b) is not isolated mutually, and cleaning is with brushing (52) by suitably by being pressed on the rotating brush (51).Therefore, dust is removed from the brush (51b) of rotating brush (51) more effectively.By above action, the brush (52b) that dust is cleaned with brush (52) is caught.Rotating brush (51) stops after rotating to original state (state of Figure 14 (A)).

Then, shown in Figure 14 (D), rotating brush (51) is the anglec of rotation of (counterclockwise) rotation regulation towards the left side once more.So, clean the brush (51b) that dust with brush (52b) seizure of brush (52) is rotated brush (51) and brushes, and fallen into the reservoir (62) of dust hold-up vessel (60).The bristle of the brush (51b) of rotating brush (51) tilts towards direction of rotation, and therefore, dust falls from brush (52b) brush of cleaning with brush (52) conscientiously.At this moment, also with above-mentioned same since cleaning with brush (52) by spring portion (52c) suitably by being pressed on the rotating brush (51), therefore, dust is removed with brushing (52) from cleaning more effectively.According to above action, the dust that is rotated brush (51) seizure is removed, and is stored in the reservoir (62) of dust hold-up vessel (60).Then, original state (state of Figure 14 (A)) is returned in rotating brush (51) (clockwise) rotation towards the right side once more, and " brush cleaning action " finishes.

If " brush cleaning action " finishes, so, carry out above-mentioned " dedusting action " once more.That is, if air cleaner (30) rotates once more, the control lever (44a) of limit switch (44) moves once more, and so, air cleaner (30) will stop.Like this, in air cleaner (30), the dust in the zone that the brush (51b) of rotating brush (51) passes through is rotated the brush (51b) of brush (51) and catches (state of Figure 14 (A)).So interactive mode repeats " dedusting action " and " brush cleaning action ".As a result, in air cleaner (30), the dust in each regulation zone all is removed.If by dedusting, so, " dedusting action " and " brush cleaning action " will finish fully in the whole zone of air cleaner (30).For example, if the number of times of the control lever (44a) of limit switch (44) action regulation so, judges that air cleaner (30) has rotated once above-mentioned release.

Herein, in above-mentioned " dedusting action " and " brush cleaning action ", the dust storage capacity in the dust hold-up vessel (60) is detected parts (70) by storage capacity and detects.That is, the transparency window (64,65) of the light transmission reservoir (62) of emitting led (72) and inner dust thereof.The luminosity of the light that sees through is detected by phototransistor (73).If the luminosity that detects of phototransistor (73) becomes below the setting value (lower limit), so, judge that dust is stored to ormal weight in dust hold-up vessel (60), switch to " dust transport action " then.

In " dust transport action ", rotating brush (51) and air cleaner (30) become halted state.In addition, the brush (51b) of rotating brush (51) is the state of contact with air cleaner (30).In addition, the baffle plate (82) of baffle plate box (81) becomes open mode (state of Figure 11 (B)).Under this state, indoor fan (21) is driven.The blow out air of indoor fan (21) is introduced into dust hold-up vessel (60) by introducing pipeline (86) and baffle plate box (81) successively.Like this, the dust of dust hold-up vessel (60) and air are together carried to dust catch (90) by conveyance conduit (88).So in dust hold-up vessel (60), the storage capacity of dust reduces, meanwhile the luminosity that detects of phototransistor (73) increases.Become more than the setting value (higher limit) if this detects luminosity, so, judge that the dust in the dust hold-up vessel (60) nearly all is transferred (discharge), " dust transport action " finishes.Then, restart " dedusting action " or " brush cleaning action ".

In addition, in above-mentioned " dust transport action ", detecting under the situation that luminosity is difficult to rise (for example, detecting luminosity under the indeclinable situation of certain hour) of phototransistor (73), judge that air does not flow through exactly in introducing pipeline (86) and conveyance conduit (88).For example, owing to stop up in introducing pipeline (86) etc., perhaps baffle plate (82) breaks down and reason such as does not open, and air-flow is hindered.In the case, indoor fan (21) is stopped, stopping " dust transport action " then.By the maintenance etc., after above-mentioned condition is eliminated, restart " dust transport action ".

In addition, in the filter cleaning action of present embodiment, condition is carried out " dust discharging operation " according to the rules.For example, if " dust transport action " carries out stipulated number (stipulated time), so just carry out " dust discharging operation ".In addition, also can be undertaken by user's remote control actions.

In " dust discharging operation ", same with above-mentioned " dust transport action ", rotating brush (51) and air cleaner (30) become halted state.In addition, the baffle plate (82) of baffle plate box (81) becomes closed condition (state of Figure 11 (C)).Under this state, the user inserts the flexible pipe of dust catcher in the dust catcher insertion mouth of decorative panel (11).Attract action according to this, the dust of dust catch (90) is successively by being inhaled in the dust catcher behind conveyance conduit (88), dust hold-up vessel (60) and the attraction pipeline (87).At this moment, the dust in the dust hold-up vessel (60) also is inhaled in the dust catcher by attraction pipeline (87).As a result, the dust of dust catch (90) and dust hold-up vessel (60) is discharged outside casing (10).

The effect of embodiment

In the present embodiment, in " brush cleaning action ",, make air cleaner (30) return the rotation predetermined angular making rotating brush (51) rotation utilize cleaning then with brushing before (52) remove dust.Like this, in the brush (51b) of rotating brush (51), can prevent the inequality of the dust from air cleaner (30), removed, thereby make dust equably attached to top.Therefore, can prevent the dust that from air cleaner (30), is removed become fall into behind the piece indoor etc.And, utilize cleaning can fall (removing) dust from rotating brush (51) brush at an easy rate with brush (52).So just can improve the reliability of the indoor units (1) of the cleaning function that possesses air cleaner (30).

In addition, in the present embodiment, in rotating brush (51), brush (51b) only is set on the part of circumferencial direction, but, owing to utilize cleaning can remove the dust of the brush (51b) of rotating brush (51) with brushing (52), therefore, the dust collection capacity that can keep rotating brush (51), and can reduce the fee of material of rotating brush (51).

In addition, in the present embodiment, make the rotation of air cleaner (30) batch (-type) ground, interactive mode is carried out " dedusting action " and " brush cleaning action " then.Therefore, the dust of from air cleaner (30), removing (that is, it being stored in the dust hold-up vessel (60)) not only can be handled conscientiously, simultaneously, high efficiency of dust collection can be in whole air cleaner (30), kept.So just can further improve the reliability of indoor units (1).

In addition, in the present embodiment, form discoideus air cleaner (30) rotation, air cleaner (30) and rotating brush (51) are relatively moved by making.Therefore, its situation about moving of sliding is compared, can be saved the space that air cleaner (30) moves with for example air cleaner (30) being formed rectangle.So just can realize the miniaturization of indoor units (1).

In addition, in the present embodiment, carry dust then in the blow out air introducing dust hold-up vessel (60) with indoor fan (21).Therefore, need not to be provided with separately the conveying mechanism that attracts fan etc., just can make the dust of dust hold-up vessel (60) move to the determined location of discarding easily at an easy rate.Like this, can not cause the maximization of device and increase cost, can improve the treatment effeciency of dust.

In the present embodiment, because dust hold-up vessel (60) is configured in the below of air cleaner (30), therefore, it becomes the resistance (obstruction circulation of air) of circulation of air.Therefore, must dwindle the volume of dust hold-up vessel (60) as far as possible.Like this, just can't in dust hold-up vessel (60), store a large amount of dust.Therefore, in the present embodiment, the big dust catch (90) of volumetric ratio dust hold-up vessel (60) is set in the position that can not hinder circulation of air, carries dust to dust catch (90) from dust hold-up vessel (60).Therefore, can dwindle dust hold-up vessel (60) as far as possible thus suppress to suck the circulating resistance of air, can store the dust of from air cleaner (30), removing in a large number simultaneously.As a result, the trouble that the user handles dust can be reduced, and the decline of air conditioning function can be prevented.

In addition, in the present embodiment, the brush (51b) of rotating brush (51) and cleaning adopt fuzz fabric to constitute with the brush (52b) of brush (52).Therefore, the hair of brush (51b, 52b) shortens, and can dwindle rotating brush (51) and the cleaning space that is provided with brush (52).As a result, can further dwindle indoor units (1).

In addition, because rotating brush (51) and cleaning are short with the hair of the brush (51b, 52b) of brush (52), and, because the brush (51b) of rotating brush (51) only is set on the part of circumferencial direction, therefore, in dust hold-up vessel (60), can reduce the circulating resistance of air (that is the blow out air of indoor fan (21)).So just can improve the transfer efficiency of dust transport action and the discharge efficient of dust discharging operation.

And, since the brush (51b) of rotating brush (51) use its bristle towards with the moving direction (direction of rotation) of air cleaner (30) over against the inclination lint, therefore, can be easy to and dust that accurately scrubbing brush falls air cleaner (30).In addition, according to the counter-rotating of air cleaner (30), be easy to make dust equably attached on the whole brush (51b).In addition, because cleaning is also used the inclination lint with the brush (52b) of brush (52), therefore, can be easy to and accurate scrubbing brush falls the dust of rotating brush (51).
