At above-mentioned storage capacity, detect in mechanism (70), the brightness that sees through successively the light of the first transparency window (64) and the second transparency window (65) from emitting led (72) is detected by phototransistor (73).Then,, according to detected next luminosity, the storage capacity of the dust in reservoir (62) (being compactedness) is detected.That is, if the storage capacity of dust is few, so, the transmitance of the light seeing through to the second transparency window (65) from the first transparency window (64) in reservoir (62) increases, and detected next brightness is higher.On the contrary, if the storage capacity of dust is many, so, and the transmitance step-down of the light seeing through to the second transparency window (65) from the first transparency window (64) in reservoir (62), detected next brightness reduces.Therefore, according to this storage capacity, detect mechanism (70), can detect in reservoir (62) and have or not dust.
As depicted in figs. 1 and 2, above-mentioned dust transport mechanism (80) comprising: above-mentioned pipeline (81) for conveyance, fan (82), exhaust outlet (83) for conveyance, attract by pipeline (84) and dust catcher insert port (85).
Above-mentioned for conveyance in pipeline (81), as flowing into one end of a side, be connected with the conveyance mouth (67) of reservoir (62) in dust hold-up vessel (60), as the other end of outflow one side, be connected with dust catch described later (90).This is pipeline (81) employing flexible pipe formation for conveyance.
Above-mentioned for conveyance attraction one side of fan (82) be connected with dust catch (90).This link position is and end dust catch (90) and the contrary side of link position pipeline for conveyance (81).Air-supply one side (blowing out a side) of fan for conveyance (82) is connected with the exhaust outlet (83) that connects housing (10).Fan for conveyance (82) utilizes sucking action will be stored in dust and air one dust catch (90) conveyance in the same way in dust hold-up vessel (60).When this conveyance action, in dust hold-up vessel (60), air (room air) is imported from outside by mesh portion (66).So, in the present embodiment, by the air-flow being produced by fan for conveyance (82), the dust of dust hold-up vessel (60) by conveyance to assigned position.
Above-mentioned for attraction one end as inflow side of pipeline (84) be connected with the end of link position phase the same side pipeline for conveyance (81) with in dust catch (90).Attract the other end that flows out a side with the conduct of pipeline (84) to be connected with the dust catcher insert port (85) in the upper formation of decorative panel (11).This dust catcher insert port (85) is to insert the flexible pipe etc. of dust catcher the opening attracting.In addition, attract to adopt flexible pipe to form with pipeline (84).According to this structure, the dust by conveyance to dust catch (90) is reclaimed by dust catcher.When this reclaims action, in dust hold-up vessel (60), air (room air) is imported from outside by mesh portion (66).
So, mesh portion (66) by dust hold-up vessel (60) gives gas effect, the pressure balance of dust hold-up vessel (60) and dust catch (90) becomes suitable, therefore, can carry out definitely conveyance action and the discharging operation (the recovery action of dust catcher) of dust.
As shown in Figures 1 and 2, as mentioned above, the dust in dust hold-up vessel (60) is then stored in wherein by conveyance above-mentioned dust catch (90).Dust catch (90) roughly forms slightly elongated rectangular shape, is configured in equally the below of demarcation strip (25) with dust hold-up vessel (60).Dust catch (90) is according to not covering one end limit configuration of the mode of air cleaner (30) along demarcation strip (25) in plane.Like this, can not hinder the circulation of the air sucking from suction grid (12).
The volume of the volumetric ratio dust hold-up vessel (60) of above-mentioned dust catch (90) is large.Plane is looked dust catch (90), and the part of connection one side of fan for conveyance (82) diminishes with another part phase specific area.In addition, the side plate of air cleaner (30) one sides of dust catch (90) is circular-arc with the corresponding formation of periphery of air cleaner (30).And, in dust catch (90), in the coupling part of fan for conveyance (82), be provided with filter (91).Therefore, by conveyance, the dust to dust catch (90) can not flow out from exhaust outlet (91).
Running action
Below, with reference to Fig. 9～Figure 11, the running action in above-mentioned indoor unit (1) is described.Indoor unit (1) is configured to and can switches the filter cleaning running of carrying out the common running of cooling/heating and air cleaner (30) being cleaned.
(running conventionally)
In conventionally turning round, as shown in Fig. 9 (C), make rotary brush (51) rotation, make its brush (51b) be positioned at brush (52) one sides for cleaning.; rotary brush (51) is rotated to the brush (51b) of rotary brush (51) position of ingress of air filter (30) not; then make the non-brush face (that is the outer peripheral face of the rotating shaft (51a) of brush (51b), is not set) of rotary brush (51) towards air cleaner (30).In addition, air cleaner (30) and for conveyance fan (82) be halted state.
Under this state, indoor fan (21) is driven.So in indoor unit (1), the room air sucking from suction inlet (13) is by flowing in horn mouth (24) air cleaner (30).When air passes through air cleaner (30), airborne dust is 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, from each blow-off outlet (14), is supplied to indoor.Carry out so indoor refrigeration or heating.
In addition,, in this running, as mentioned above, brush (51b) and the air cleaner (30) of rotary brush (51) are contactless state.Therefore, can prevent brush (51b) continuous contact air cleaner (30) and the wearing and tearing that cause.Like this, the durability of rotary brush (51) improves.
(filter cleaning running)
In filter cleaning running, in refrigerant loop, compressor is stopped, and cold-producing medium becomes the state not circulating.In this filter cleaning running, can switch " dedusting action ", " brush cleaning action ", " dust conveyance action " and " dust discharging operation ".
" dedusting action " is the action of removing the dust being caught by air cleaner (30)." brush cleaning action " is to remove the action that is attached to the dust on rotary brush (51)." dust conveyance action " is the action from dust hold-up vessel (60) to dust catch (90) conveyance dust." dust discharging operation " is from dust catch (90), to housing (10), to discharge the action of dust, that is, it is that the dust of dust catch (90) is recycled to the action in dust catcher.
In the present embodiment, interactive mode is carried out " dedusting action " and " brush cleaning action ".First, in " dedusting action ", indoor fan (21) stops.Then, as shown in Fig. 9 (A), make rotary brush (51) rotation, make its brush (51b) ingress of air filter (30).Under this state, air cleaner (30) is along direction (counterclockwise) rotation shown in the middle arrow of Fig. 9 (A).That is, arrow as shown in figure 10 (hollow arrow), air cleaner (30) moves towards mode in opposite directions according to the bristle of the brush with rotary brush (51) (51b).In addition, now, rotary brush (51) keeps halted state.
So the brush (51b) that the dust of air cleaner (30) is rotated brush (51) catches (with reference to Figure 11 (A)).Then, if the action of the control lever (44a) of the limit switch (44) of filter driving mechanism (40), so, filter drive motors (41) will stop, and air cleaner (30) stops thereupon.That is, after the angle of only rotation regulation of air cleaner (30), stop.Therefore,, in air cleaner (30), the dust in the region that the brush (51b) of rotary brush (51) passes through is removed.Herein, the bristle of brush (51b) tilts opposite to each other towards the direction of rotation with air cleaner (30) (moving direction), and therefore, the dust of air cleaner (30) is easy to be brushed off by brush (51b).So the efficiency of dust collection of rotary brush (51) improves.If air cleaner (30) stops, so, from " dedusting action ", switching to " brush cleaning action ".
In " brush cleaning action ", under the state that continues to stop at indoor fan (21) and rotary brush (51), first, air cleaner (30) is along direction (clockwise) rotation shown in arrow in Fig. 9 (B).That is, air cleaner (30) contrary direction when with " dedusting action ", with the bristle of the brush (51b) of rotary brush (51) towards identical direction rotation.In addition, in the present embodiment, make the distance of the width of air cleaner (30) brush (51b) that is equivalent to rotary brush (51) in rotary moving.So, the dust accumulating between air cleaner (30) and brush (51b), that is, the dust being just removed from air cleaner (30) is attached on brush (51b) equably.Like this, the dust of air cleaner (30) is caught by brush (51b).Therefore, can improve the efficiency of dust collection of rotary brush (51).
Then,, in " brush cleaning action ", under the state stopping at indoor fan (21), rotary brush (51) rotates towards left side (counterclockwise) in Figure 11.Now, rotary brush (51) has caught under the state of dust and has rotated on brush (51b).In addition, rotary brush (51) and cleaning are in contact with one another with the brush (51b, 52b) of brush (52), simultaneously rotary brush (51) rotation (with reference to Figure 11 (B)).After the anglec of rotation of rotary brush (51) rotation regulation, will stop.
Then, rotary brush (51) rotates according to direction contrary to the above (that is, the right side in Figure 11 (clockwise)).So the dust that is rotated brush (51b) seizure of brush (51) is cleaned with the brush (52b) of brush (52) removes (with reference to Figure 11 (C)).Clean the bristle of the brush (52b) of using brush (52) towards down,, bristle tilts towards the direction in opposite directions of the direction of rotation towards with rotary brush (51), and therefore, dust is brushed off from the brush (51b) of rotary brush (51).In addition, two brushes (51b, 52b) are in contact with one another, cleaning is just pushed to rear with the main part (52a) of brush (52) like this, and still, main part (52a) is exerted pressure towards rotary brush (51) one sides by spring portion (52c).Like this, brush (51b, 52b) is isolation mutually, cleaning with brush (52) by exactly by being pressed on rotary brush (51).Therefore, dust is removed by the brush (51b) from rotary brush (51) more accurately.By above action, the brush (52b) that dust is cleaned with brush (52) catches.Rotary brush (51) rotation stops to original state (state of Figure 11 (A)).
Then, rotary brush (51) again towards left side (counterclockwise) only rotate predetermined angular.So, by cleaning, with the brush (51b) that the dust of brush (52b) seizure of brush (52) is rotated brush (51), brushed off, and fall into the reservoir (62) (with reference to Figure 11 (D)) of dust hold-up vessel (60).The bristle of the brush (51b) of rotary brush (51) is towards tilting towards direction of rotation, and therefore, dust is brushed off with the brush (52b) of brush (52) from cleaning.Now, also with above-mentioned same, because cleaning is suitably upper by being pressed in rotary brush (51) by spring portion (52c) with brush (52), therefore, dust is brushed off with brush (52) from cleaning.By 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, rotary brush (51) (clockwise) rotation towards right side again, returns to original state (state of Figure 11 (A)), and " brush cleaning action " temporarily finishes.
If " brush cleaning action " finishes, so, again carry out above-mentioned " dedusting action ".That is, if air cleaner (30) rotates again, the control lever (44a) of limit switch (44) moves again, and so, air cleaner (30) stops.Like this, in air cleaner (30), the brush (51b) that the dust in the region of the brush (51b) by rotary brush (51) is rotated brush (51) catches (state of Figure 11 (A)).So interactive mode repeats " dedusting action " and " brush cleaning action ".As a result, in air cleaner (30), the dust in each regulation region is removed.If dust is all removed in the whole region of air cleaner (30), so, " dedusting action " and " brush cleaning action " will finish completely.For example, if the number of times of the control lever (44a) of limit switch (44) action regulation, so, judgement air cleaner (30) has rotated once, above-mentioned release.
But " dust conveyance action " often carried out once or repeatedly, all carried out to above-mentioned " brush cleaning action ".
In " dust conveyance action ", rotary brush (51) is stopped under the state of Figure 11 (A), and meanwhile, air cleaner (30) becomes halted state.Under this state, fan for conveyance (82) is driven.So the air of dust catch (90) is discharged from from exhaust outlet (83).Meanwhile, the dust of dust hold-up vessel (60) and air together by conveyance pipeline (81) to dust catch (90) by conveyance (attraction).Then, again carry out " dedusting action " and " brush cleaning action ", and carry out " dust conveyance action ".By repeating these actions, dust will be stored in dust catch (90) gradually.If the dust trunkful of dust catch (90), so, no matter carry out how many times " dust conveyance action ", dust can be from dust hold-up vessel (60) to dust catch (90) conveyance, and dust will accumulate in dust hold-up vessel (60) gradually.On the other hand, in dust hold-up vessel (60), dust storage capacity is detected mechanism (70) by storage capacity and detects.Although carried out " dust conveyance action ", but, if accumulate the dust of ormal weight in the reservoir (62) of dust hold-up vessel (60), so, storage capacity detects the detecting brightness and will become below setting value of phototransistor (73) of mechanism (70).With regard to detecting the dust of dust catch (90), be trunkful state like this.
In the filter cleaning running of present embodiment, as mentioned above, if detect the trunkful state of dust catch (90), so, just start to carry out " dust discharging operation ".In " dust discharging operation ", same with above-mentioned " dust conveyance action ", rotary brush (51) is stopped under the state of Figure 11 (A), and meanwhile, air cleaner (30) becomes halted state.In addition, for conveyance, fan (82) also becomes halted state.Under this state, user inserts the flexible pipe of dust catcher in dust catcher insert port (85).According to this, attract action, the dust of dust catch (90) is inhaled in dust catcher by attraction pipeline (84).Now, the dust in dust hold-up vessel (60) is also inhaled in dust catcher with pipeline (84) by conveyance pipeline (81), dust catch (90) and attraction successively.As a result, the dust of dust catch (90) and dust hold-up vessel (60) is just reclaimed by dust catcher.That is, the dust of dust catch (90) etc. is discharged from outside housing (10).
The effect of embodiment
In the present embodiment, because dust hold-up vessel (60) is positioned at the below of air cleaner (30), therefore, it becomes the resistance (obstruction circulation of air) of circulation of air.Therefore, must dwindle dust hold-up vessel (60) as far as possible.Therefore, in the present embodiment, the dust catch (90) that volumetric ratio dust hold-up vessel (60) is large is set in the place that can not hinder circulation of air, utilize fan for conveyance (82) by the dust conveyance of dust hold-up vessel (60) to dust catch (90).Like this, user needn't bother, and a large amount of dust terminal storages that just can will remove from air cleaner (30) are in dust catch (90).As a result, can reduce the trouble of user's processing dust.
In addition, owing to can, by the dust terminal storage of air cleaner (30) in dust catch (90), therefore, realizing the miniaturization of dust hold-up vessel (60).As a result, can reduce the circulating resistance of the air amount in indoor unit (1), running efficiency improves.
And, in the present embodiment, owing to being provided with, attract, by pipeline (84) and dust catcher insert port (85), therefore, can at an easy rate the dust of dust catch (90) be expelled to outside housing (10).So just can further reduce the trouble of processing dust.
In addition, in the present embodiment, owing to being provided with rotary brush (51) in dust hold-up vessel (60), therefore, can guarantee to be stored in dust hold-up vessel (60) being rotated the dust that brush (51) removes.In addition,, owing to making air cleaner (30) mobile in the face of rotary brush (51), therefore, can remove the dust on the whole surface of air cleaner (30).In the situation that adopting this structure, the volume of dust hold-up vessel (60) and configuration will be subject to further restriction, but, in the present embodiment, owing to can making at an easy rate dust move to dust catch (90) from dust hold-up vessel (60), therefore, can effectively store a large amount of dust.
In addition, in the present embodiment, the brush (51b) of rotary brush (51) adopts fuzz fabric to form.Therefore, the hair root of brush (51b) is shorter, therefore, can reduce the space that arranges of rotary brush (51).In addition, because the hair root of brush (51b) is shorter, and this brush (51b) is only arranged in the part of circumferencial direction for rotary brush (51), therefore, in dust hold-up vessel (60), can reduce the resistance of circulation of air.As a result, can improve the conveyance efficiency of dust conveyance action and the expulsion efficiency of dust discharging operation.
In addition, in the present embodiment, when the common running of cleaning air filter (30) not, make the brush (51b) of rotary brush (51) and air cleaner (30) become contactless state.Therefore, can prevent the long-time continuous contact of brush (51b) and air cleaner (30) and the wearing and tearing that cause.Like this, the durability of rotary brush (51) not only can be improved, and dedusting function can be kept for a long time.
Particularly in the present embodiment, in a part for circumferencial direction in rotary brush (51), be provided with brush (51b), therefore, as long as make rotary brush (51) rotation, just can make at an easy rate rotary brush (51) and air cleaner (30) become contactless state.In addition,, owing to only in a part for the circumferencial direction of rotary brush (51), brush (51b) being set, therefore, can reduce the fee of material of brush (51b), thereby can reduce the cost of dedusting mechanism (50).
In addition, in the present embodiment, in dedusting mechanism (50), be equipped with brush (52) for cleaning.Therefore, can really remove and be rotated the dust of brush (51) seizure and it is stored in dust hold-up vessel (60).Therefore, can prevent from because dust seizure amount increases the dedusting function causing, declining in rotary brush (51).So just can improve the efficiency of dust collection to air cleaner (30).
And, in the present embodiment, make the angle of the each rotation regulation of air cleaner (30), then interactive mode is carried out dedusting action and brush cleaning action, therefore, can in whole air cleaner (30), keep high efficiency of dust collection.So just can really remove the dust of whole air cleaner (30).
The variation of embodiment
Below, the variation of above-mentioned embodiment is described.
(variation 1)
As shown in Figure 12 and Figure 13, this variation 1 changes the structure of the dust transport mechanism (80) in above-mentioned embodiment.
Particularly, in this variation, fan for conveyance (82) is connected with the end of dust hold-up vessel (60).That is, the end of in dust hold-up vessel (60) and the contrary side of link position pipeline for conveyance (81) connects air-supply one side (blowing out a side) of fan (82) for conveyance.In addition, dust catch (90) is connected with exhaust outlet (83) with the end of the contrary side of link position of pipeline (84) with pipeline for conveyance (81) and attraction.In the coupling part of this dust catch (90), filter (91) is set.
In this variation, in " dust conveyance action ", air is blown to dust hold-up vessel (60) from fan for conveyance (82).Like this, the dust of dust hold-up vessel (60) and air together by conveyance pipeline (81) by conveyance to dust catch (90).Now, the air of dust catch (90) passes through filter (91) by (83) discharge after exhaust.Like this, the pressure balance of dust hold-up vessel (60) and dust catch (90) becomes suitable.In addition,, owing to being provided with filter (91) in dust catch (90), therefore, by the dust of conveyance, can not flowed to outlet (83).So in this variation, the air-supply effect by conveyance fan (82) will be stored in dust conveyance in dust hold-up vessel (60) to dust catch (90).Other structure, effect and effect and above-mentioned embodiment are same.
(variation 2)
This variation 2 arranges air velocity transducer (69) and detects mechanism (70) to replace storage capacity in the dust hold-up vessel (60) of above-mentioned embodiment and variation 1 thereof.
Particularly, in the dust hold-up vessel (60) of above-mentioned embodiment, as shown in figure 14, air velocity transducer (69) is set near the inner side of mesh portion (66).In addition,, in the dust hold-up vessel (60) of above-mentioned variation 1, as shown in figure 15, air velocity transducer (69) is set near the blow-off outlet of fan for conveyance (82).That is,, in any one dust hold-up vessel (60), be stored in reservoir (62) wherein with dust and compare in the upstream of air-flow one side air velocity transducer (69) is set.This air velocity transducer (69) is the flow rate detection mechanism detecting according to the air velocity of the sucking action of fan for conveyance (82) or air-supply effect (that is, wind speed).
In this variation, according to the value of detecting of air velocity transducer (69), detect trunkful state and obstruction in pipeline (81) etc. for conveyance of the dust of dust catch (90).Particularly, in " dust conveyance action ", the wind speed in dust hold-up vessel (60) is detected by air velocity transducer (69).Herein, when dust is not stored in dust catch (90) too much, the value of detecting of air velocity transducer (69) is lower.That is, owing to almost there is no dust at dust hold-up vessel (60) to the air duct of dust catch (90), therefore, the circulating resistance of air diminishes, and wind speed increases.Afterwards, along with the dust of dust hold-up vessel (60) and air together by conveyance to dust catch (90), the dust storage capacity of dust catch (90) increases, therefore, the circulating resistance of air increases, wind speed reduces.If the dust of dust catch (90) becomes trunkful state (ormal weight), so, value of detecting (wind speed) of air velocity transducer (69) becomes below setting.Like this, the dust that detects dust catch (90) becomes trunkful.If detect the trunkful state of this dust catch (90), so, fan for conveyance (82) stops, and carries out " dust discharging operation " same with above-mentioned embodiment.So just can calculate definitely the time started of " dust discharging operation ".
In addition,, the in the situation that of occurring to stop up in pipeline for conveyance (81) and dust hold-up vessel (60), the circulating resistance of air also can increase, wind speed decreased.Therefore, according to value of detecting of air velocity transducer (69) (wind speed), become the following this point of setting, can infer in pipeline for conveyance (81) etc. obstruction has occurred.Eliminate obstruction by maintenance after, restart " dust conveyance action ".
As previously discussed, owing to being provided with air velocity transducer (69) in dust hold-up vessel (60), therefore,, in " dust conveyance action ", can detect dust hold-up vessel (60) and the variation of the circulation of air resistance in pipeline (81) for conveyance.According to the variation of this circulating resistance, can detect the trunkful state of the dust of dust catch (90).As a result, can calculate definitely the time started of " dust discharging operation ".
