Namely, the arm 291c that the opaque component 291b of the present embodiment extends while the end side be formed in depth direction of the both sides of basal part 291c of thin shape and central authorities with depth dimensions d3 tilts, forms anterior up-down wind direction board rotating shaft 291f in the end of this arm 291e.In addition, between each arm 291e, be provided with the auxiliary wind direction board 291d configured abreast with basal part 291c.

On the other hand, transparent component 291a is the transparent thin component with depth dimensions d1.This transparent component 291a is formed as roughly aliging with the end of arm 291e side, has just in time stretched out depth dimensions d5 towards another end side than the end of opaque component 291b.In addition, transparent component 291a implements back up in the scope at the back side contacted with opaque component 291b.

That is, rear side is divided into 2 parts at degree of depth wind direction by transparent component 291a, carries out back up to the arm 291e side becoming rotation shaft side, defines another side becoming front relative to anterior up-down wind direction board rotating shaft 291f pellucidly.Thus, can't see unwanted opaque component 291b in appearance, the leading section of anterior up-down wind direction board 291 can be made transparent on the other hand, this improves aesthetic appearance, and the constriction that the action that can alleviate anterior up-down wind direction board 291 brings.Such as, the opaque processing unit 9 (part contacted with opaque component 291b) of transparent component 291a can cover, and makes can't see to support the shaft portion of anterior up-down wind direction board 291 (anterior up-down wind direction board rotating shaft 291f) etc.In addition, attachment features such as can't see burnt electric type infrared ray sensor 17, radiation sensor 18, sound transducer 19 can be made.

The side view of the mounting portion of the sound transducer 19 when Figure 13 is closedown anterior up-down wind direction board 291.As shown in Figure 13, under the halted state of air conditioner 1, can be adjacent to hold anterior up-down wind direction board 291 with the bottom of the movable platen 251 of the front portion of covering front side air intake parts 270`.Therefore, under the state that this anterior up-down wind direction board 291 is received, because the leading section of anterior up-down wind direction board 291 is formed transparent, so user across this transparent part, can see the part in upholstery face 24.In the present embodiment, no matter under operating condition or the halted state that operates, the upholstery face 24 that user can see zonally forms the inside display unit 22 of display operating condition.In addition, Jiao's electricity type infrared ray sensor 17 of action during running, radiation sensor 18 and sound transducer 19 are configured in the dorsal part in the upholstery face 24 of being blocked by anterior up-down wind direction board 291.

Figure 14 is front view when closing anterior up-down wind direction board 291.Figure 15 is front view when opening anterior up-down wind direction board 291.

As shown in Figure 14, before being turned off during portion's up-down wind direction board 291, by top (with reference to Figure 12), display window 22b (with reference to Fig. 9), the display opening 22a (with reference to Fig. 9) of the transparent component 291a of anterior up-down wind direction board 291, can identification sensor module 16 (with reference to Fig. 9) display lamp 397a (with reference to Fig. 9) light/extinguish, therefore, the Presentation Function of display unit 397 can be maintained, transmit appropriate information to user.In addition, portion's up-down wind direction board 291 moment before being turned off, in the moment that the running being not limited to air conditioner 1 stops, such as after warming operation starts, the temperature of indoor heat converter 33 is low sometimes, and the waste heat carrying out indoor heat converter 33 with the running of indoor Air Blast fan 311 accordingly operates.In this case, display unit 397 shows the purport (such as carrying out showing enabling user to identify according to the position of the display lamp 397a lighted, color) of waste heat running.In addition, before being turned off during portion's up-down wind direction board 291, the opening portion (burnt electrical aperture 24c, radiation opening 24d, intercommunicating pore 24b) of burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19 cannot be seen in indoor, become succinct outward appearance.

As shown in figure 15, before opening during portion's up-down wind direction board 291, the display window 22b of inner display unit 22 exposes, can the lighting/extinguish of display lamp 397a (with reference to Fig. 9) of identification sensor module 16 (with reference to Fig. 9).In addition, open the anterior up-down wind direction board 291 of opening portion (burnt electrical aperture 24c, radiation opening 24d, intercommunicating pore 24b) and the indoor living space having covered burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19, the function of each sensor can be played.

Like this, what the air conditioner 1 of the present embodiment possessed the opening portion (burnt electrical aperture 24c, radiation opening 24d, intercommunicating pore 24b) being difficult to indoor see burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19 blocks component (the opaque component 291b of anterior up-down wind direction board 291).

Thus, when not using burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19 (when air conditioner 1 stops), as shown in Figure 3, burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19 is covered with blocking component (opaque component 291b), can become and there is no unnecessary concavo-convex succinct outward appearance, the atmosphere of interior decoration can not be destroyed.

In addition, due to by a part for anterior up-down wind direction board 291 as blocking component (opaque component 291b), so do not need special blocking component and block member drives parts.

In addition, inner display unit 22 is covered by transparent component 291a, but when operating stopping, anterior up-down wind direction board 291 erects subvertical angle and makes to be suitable for framework 20, therefore, when on-wall type air conditioner 1 is seen like that from bottom to top, only when the display lamp 397a of sensor assembly 16 does not light, the reflection on the surface of transparent component 291a produces and affects more by force, cannot see the inside display unit 22 at its back, succinct outward appearance can be become, the atmosphere of interior decoration can not be destroyed.

In addition, even if under the state of portion's up-down wind direction board 291 before being turned off, if light the display lamp 397a of sensor assembly 16, then can confirm running display, therefore, in order to start to prevent cold wind when waiting at warming operation, to the temperature rising of indoor heat converter 33, close anterior up-down wind direction board 291 always, in indoor Air Blast fan 311 also out-of-operation warming up process, also correctly can confirm operating condition.

< filter sweeping mechanism >

Then, use Figure 16, Figure 17, the cleaning agency of filter 231,231` is described.Figure 16 is the figure that filter sweeping mechanism 230 is seen in the top side of machine 2 indoor, and Figure 17 (a) is the stereogram of filter sweeping mechanism 230, and (b) is the stereogram only demonstrating hairbrush.

Filter sweeping mechanism 230 comprises scanner 232 with hairbrush 267,267` scavenge filter 231,231`, holds dust-collection element 280, the 280` of the dust scanned out.

On the upside air intake parts 270 (with reference to Fig. 2) of the upstream of faced chamber's inside heat exchanger 33 (with reference to Fig. 2) and two faces of front side air intake parts 270` (with reference to Fig. 2), be provided with plane filter 231,231`.Filter 231,231` are connected with guide housing 234, and guide housing 234 possesses track 235,235` at rear portion, upside and lower front, possess cardan shaft 243 at the cross section of filter 231,231`.

Cardan shaft 243 has polygonal cross section, is arranged on the bearings on guide housing 234, via the gear on the one end of the bearing 245 that to be arranged on through one-sided, is connected with the movement motor 242 be fixed on guide housing 234.On cardan shaft 243, loosely is provided with screw 244, bracket 261, and screw 244 is arranged on guide housing 234, is engaged abreast with cardan shaft 243 with shelf (rack) 237.

Between bracket 261 and track 235,235`, stride across filter 231,231` and set up hairbrush carriage 262,262` respectively, hairbrush carriage 262,262` are provided with the hairbrush 267, the 267` that clean filter 231,231`.

By making movement motor 242 rotate, cardan shaft 243, screw 244 rotate, and screw 244 moves at left and right directions accordingly along the direction of rotation of shelf 237 and movement motor 242, and bracket 261 is moved.Thus, hairbrush 267,267` carry out moving and wipe with filter 231,231` and connect while clean, and the dust on filter 231,231` are swept to hairbrush 267,267`, and move it dust-collection element 280, the 280` of the left part of guide housing 234.

Dust-collection element 280,280` remove the dust that is attached on hairbrush 267,267` and hold.In addition, be also for making hairbrush 267,267` clean and be clean next time prepare hairbrush 267,267` cleaning part.

Then, use Figure 18, structure and the action of filter sweeping mechanism 230 are described.Figure 18 is the action specification figure of filter sweeping mechanism 230.

Possess the hairbrush 267 when not carrying out cleaning action in the right of filter 231 and carry out standby standby components.

When carrying out cleaning action, make scanner 232 (with reference to Figure 17) action, hairbrush 267 (A of Figure 18) standby in standby components is moved from right to left, makes the swept filter 231 (C with reference to Figure 18) of this hairbrush 267.At this, the hair end of hairbrush 267 is relative to becoming open state (A with reference to Figure 18) in standby components, when moving from standby components to filter 231, due to inclination, on the face of filter 231, assembly changes hair end one side and contacts while distortion on the other hand, reliably wipes connect with filter 231.In addition, below, B is described.

Hairbrush 267 is while move up in the side of dust-collection element 280, and swept filter 231, clears away dust 236 (C with reference to Figure 18).The hairbrush 267 scanned finishing filter 231 by the D part of Figure 18, transfers to dust-collection element 280 together with the dust 236 cleared away, and removing dust 236, the dust 236 be removed is accommodated in dust-collection element 280, and hairbrush 267 becomes clean.Then, do not wipe with filter 231 mode connect with the hair end of hairbrush 267, hairbrush 267 moves (B with reference to Figure 18) from left side dust-collection element 280 to the standby components on the right.

In addition, describe and the dust after removing with the swept filter 231 of hairbrush 267 is contained in action in dust-collection element 280, but the dust removed with the swept filter 231` of hairbrush 267` being contained in the situation in dust-collection element 280` too, omit the description.

By installing such filter 231, the filter sweeping mechanism 230 of 231`, such as filter sweeping mechanism 230 can be made accordingly automatically to operate with the accumulated running time of air conditioner 1, filter 231,231` are cleaned, in filter 231,231`, too can not retain dust, the surge phenomenon of the indoor Air Blast fan 311 caused when too retaining dust in filter 231,231` can be prevented in the first place.

Like this, the air conditioner 1 of the present embodiment is by mounting filter cleaning agency 230, the surge phenomenon of indoor Air Blast fan 311 can be prevented, indoor sound can be correctly detected by for the sound transducer 19 of the sound of (in conditioned space) in sensing chamber, so, carrying out operating for inferring the activity of indoor occupant according to the sound of indoor the purposes controlled, is applicable structure.

" control of air conditioner "

Then, use Figure 19, the summary of the control of the air conditioner 1 of the present embodiment is described.Figure 19 is the block diagram of control assembly 10.

The indoor set 2 of air conditioner 1 possesses control assembly 10 in inside, with the information from various sensor, the instruction from remote controller 5 accordingly, control indoor set 2, off-premises station 6.By temperature sensor 11, humidity sensor 12, remote controller ambient temp sensor 13, remote controller position sensor 14, burnt electric type infrared ray sensor 17, radiation sensor 18, sound transducer 19 etc., information from indoor 900 is taken into the microcomputer (not shown) of the inside to control assembly 10, according to various result of calculation, control air conditioner 1.

Temperature sensor 11 is arranged near front side air intake parts 270` (with reference to Fig. 2), detects the temperature (being called " intake air temperature ") being drawn into the room air of indoor set 2 from air suction inlet 27.

Humidity sensor 12 is arranged near front side air intake parts 270` (with reference to Fig. 2), detects the humidity from the room air being drawn into indoor set 2 from air suction inlet 27.

Remote controller ambient temp sensor 13 is arranged on (with reference to Fig. 1) in remote controller 5, via transceiver unit 396 (with reference to Fig. 1), the temperature detected is input to control assembly 10.

Remote controller position sensor 14 is transceiver unit 396 (with reference to Fig. 1), detects the position of remote controller 5 (with reference to Fig. 1) according to the arrival direction of infrared signal.

Control assembly 10 possesses activity decision means 41, temperature drift value set parts 42, target temperature set parts 44, air conditioning capacity control assembly 45.

Activity decision means 41 has following function: according to the information of the electric type infrared ray sensor 17 of Jiao and sound transducer 19, as exemplified by the right side of Figure 20, point activity of several stage to indoor occupant is distinguished and judges, and is delivered to temperature drift value set parts 42.

Except from except the activity information of activity decision means 41, temperature drift value set parts 42 is also according to from above-mentioned various sensor (temperature sensor 11, humidity sensor 12, remote controller ambient temp sensor 13, remote controller position sensor 14, radiation sensor 18), the information of the calendar information 15 with calendar set-up function that possesses in control assembly 10 inside, accounting temperature deviant, and be delivered to target temperature set parts 44.

Room temperature set parts 43 is arranged on (with reference to Fig. 1) in remote controller 5, via transceiver unit 396 (with reference to Fig. 1), the temperature set by indoor occupant (design temperature) is input to the target temperature set parts 44 of control assembly 10.

Target temperature set parts 44, according to the temperature drift value information from temperature drift value set parts 42, setting room temperature information from room temperature set parts 43, calculates target temperature, and is delivered to air conditioning capacity control assembly 45.

Air conditioning capacity control assembly 45 is according to the target temperature from target temperature set parts 44, the intake air temperature information etc. from temperature sensor 11, set compressor rotary speed, indoor blower rotating speed, outdoor draft fan rotating speed by compressor rotary speed set parts 46, indoor blower speed setting parts 47, outdoor draft fan speed setting parts 48, control compressor 51, indoor blower 52, outdoor draft fan 53.

Generally, the blow out air of air conditioner 1 comes and goes in indoor circulation, the temperature (intake air temperature) being inhaled into the suction air of air conditioner 1 is detected by temperature sensor 11, the mode of the target temperature set by target temperature set parts 44 is become with intake air temperature, change the rotating speed of compressor 51, indoor blower 52, outdoor draft fan 53, change refrigeration, heating capacity, change the temperature of the blow out air of air conditioner 1, the temperature of carrying out air conditioner 1 thus regulates.

At this moment, with the intake air temperature detected by temperature sensor 11, the setting room temperature set by remote controller 5 (room temperature set parts 43) accordingly, carry out the heating capacity of air conditioner 1, the control of refrigerating capacity, but the ground that the known intake air temperature being arranged on the air conditioner 1 (indoor set 2) of indoor eminence compares the indoor at personnel place is indoor high to the temperature of the living space of the height and position of face, in order to revise this temperature difference, unnecessary setting room temperature is added the rear design temperature that adds after the setting (temperature drift value) calculated by deviant set parts 42 and be set as target temperature, controlling air conditioner 1 makes intake air temperature close to target temperature.

In addition, as the value of regulation, use the value of about-1 ~ 5 degree according to the structure of air conditioner 1, heating or freeze such operation mode and different values.

" the activity determination methods of indoor occupant "

Then, illustrate undertaken judging by activity decision means 41, be combined with burnt electric type infrared ray sensor 17 and sound transducer 19 and to the method that judges of the activity refinement of indoor occupant ground.Figure 20 is the table of the relation representing activity description and activity.

The warm sensation of known person is subject to temperature, humidity, air-flow, radiation, the impact of clothing amount and activity.Temperature (and humidity) in air conditioner 1 control room, make to keep comfortableness, but when if the action of indoor occupant (activity) changes, even if identical in other conditions, the warm sensation of this people also can change, in order to maintain comfortableness, require to change temperature (and humidity) etc. accordingly with the action of this people.In order to correspondingly, the air conditioner 1 of the present embodiment combines burnt electric type infrared ray sensor 17 and sound transducer 19, obtains with carrying out refinement, while considering the comfortableness of indoor occupant the active state of indoor occupant, control extremely meticulously, carry out energy-saving operation.

In the past, use burnt electric type infrared ray sensor 17 to detect the activity of indoor occupant, regulate low when activity is large by room temperature, the technology regulating high by room temperature at activity hour was practical.But, the activity of personnel in multistage ground divided chamber for only using burnt electric type infrared ray sensor 17, because the sensitivity of sensor is for metrical error, lower towards the motion in the direction of sensor, so the number not increasing burnt electric type infrared ray sensor is difficult, improve the cost of air conditioner 1.

In addition, when having carried out the detection of people by the electric type infrared ray sensor 17 of Jiao, if indoor occupant moves, then the exporting change of sensor, can detect the movement of indoor occupant.When indoor occupant does not move, because the output of sensor does not change, so can detect that indoor occupant does not move, but just according to the presence or absence of the movement of indoor occupant, be to judge with indoor occupant being had to the activity refinement of what degree.

In addition, there is following such method, namely in order to refinement judge the activity of indoor occupant, the electric type infrared ray sensor of multiple Jiao is set, indoor occupant have significantly move time, the electric type infrared ray sensor of multiple Jiao reacts, in the movement hour of indoor occupant, only have a sensor to react, differentiate the large and small of the activity of indoor occupant thus.

But, in the method, need the electric type infrared ray sensor of multiple Jiao, become the reason that cost improves.In addition, even if there is being the electric type infrared ray sensor of multiple Jiao, but when the movement of the indoor occupant movement that can detect than sensor is little, when carrying out identical action, there is the problem that cannot judge activity.

Use MET (Metabolic Equivalent) to be used as the unit of the activity representing people, movable content and numerical value roughly thereof are as shown in figure 20.

In the left side of Figure 20, as comparative example, the example of dividing into of activity during only to employ burnt electric type infrared ray sensor 17 is recorded.Like this, when only employing the electric type infrared ray sensor 17 of 1 Jiao, even if roughly distinguish the differentiations of segmentation activities further according to large, medium and small 3, page is due to reason as described above, and precision is insufficient.

On the right side of Figure 20, describe combinationally use the present embodiment Jiao's electricity type infrared ray sensor 17 and sound transducer 19 to distinguish the example of the situation of activity.According to the present embodiment, activity can being distinguished broken down, therefore, according to being suitable for the air-conditioning of activity of indoor occupant to consider comfortableness, can energy-saving operation be carried out.

< employs the judgement > of the activity of sound transducer and Jiao's electricity type infrared ray sensor

If indoor occupant has carried out any activity, the sound that general generation is adjoint with it.To this, by predicting the various sights of the indoor of having installed air conditioner 1 (indoor set 2), according to the testing result of the testing result of the electric type infrared ray sensor 17 of Jiao and sound transducer 19, can more correctly grasp the activity of indoor occupant.

Have various at the sound of the indoor generation of air conditioner 1 running, the sound etc. have the sound of session between the sound of air conditioner self, indoor occupant, also sending along with the sound etc. of the water pump of the sound, music, audio etc. when the indoor occupant sound that the sound of activity, indoor occupant produce by operating equipment such as dust catcher, cooking apparatus, beauty appliances by carrying out clerical operations, tailor, simple arrangement etc., indoor occupant appreciation TV, radio, sound equipment, clock and watch, aquarium even without people.

These sound can be divided into " sound along with the activity of indoor occupant " and " with the sound that the activity of indoor occupant is irrelevant ".In " with the sound that indoor occupant is irrelevant ", there is the sound etc. of the water pump of the sound of the sound of air conditioner self, TV, radio, sound appliances, music, audio, clock and watch, aquarium.In " sound along with the activity of indoor occupant ", there is the sound of session, clerical operations, tailor, simple arrangement, dust catcher, cooking apparatus, beauty appliance etc.

In the sound processed as " with the sound that the activity of indoor occupant is irrelevant ", even if the sound that the sound of the water pump of clock and watch, aquarium etc. also send when unmanned is should by as the sound of ambient sound in room having installed air conditioner 1, the sound that the operating sound of air conditioner self superposed and other sound is needed to distinguish.

Equally, also need the sound of the TV processed as " from the sound that the activity of indoor occupant is irrelevant ", radio, sound appliances, music, audio to come with the sound irrelevant as the activity with indoor occupant different with the sound of air conditioner self and other sound are distinguished.Below, TV etc. is called apparatus for receiving broadcasting group.

In addition, when using the dust catcher etc. in " sound along with the activity of indoor occupant ", indoor occupant also moves actively, therefore, need suitable air adjustment and basis on, need to distinguish with other sound.Below, will as dust catcher etc. in use indoor occupant also actively moving equipment be called heavy housework device cluster.

Equally, need the session in " sound along with the activity of indoor occupant ", use the activity of personnel in the superfine Zhi Di divided chamber of sound transducer 19.If the sound of session is little, the sound of session then can be judged as YES the state of undisturbedly having a rest, if greatly and continue incessantly, then can think that the activity of this people also increases such generality tendency neatly, therefore, need to grasp distinctively with other sound.

Equally, when the use cooking apparatus in " sound along with the activity of indoor occupant ", beauty appliance, affairs equipment etc., because indoor occupant also uses on one side a little actively, thus need with the situation using heavy housework device cluster, to conversate with quiet sound one side rest time distinguish.Below, the such as equipment that indoor occupant also moves a little in use such as cooking apparatus, beauty appliance, affairs equipment is become light housework device cluster.

Thus, the kind of the source of sound that should differentiate is between " air conditioner self ", TV etc. " apparatus for receiving broadcasting group ", dust catcher etc. " heavy housework device cluster ", cooking apparatus etc. " light housework device cluster " and indoor occupant " session ".The source of sound that cannot be identified as them has motion and the sound of intermediateness, is therefore divided into " light housework device cluster ".

If observe the words of the relation of the kind of these sources of sound and the activity (value of MET) of Figure 19, TV, Music Appreciation ... 1.0MET, indoor sweeping ... 3.0METs, culinary art ... 2.0METs, session, phone Figure 19 do not record but be 1.0 ~ 1.8METs, and air conditioner self does not change the activity of indoor occupant.

Like this, to attach most importance to based on the size of the activity of the indoor occupant of the kind of source of sound the order of housework device cluster >=light housework device cluster >=session >=apparatus for receiving broadcasting group >=air conditioner self.

Generally, the action model of the indoor that indoor occupant is stayed at home varies, and predicts it is difficult one by one to them.Therefore, the action of indoor occupant and sound indoor are at that time divided into 2 following patterns.

The first, when there is the sound along with activity in indoor occupant activity, owing to there being activity, the change of the body internal heat generation of indoor occupant increases.Below, the kind of the source of sound of the sound sent along with this activity is called " warming changes large source of sound ".

The second, although when the sound having the activity of indoor occupant to produce hardly along with activity, the change of body internal heat generation is little.Below, the kind sent not along with the source of sound of the sound of this activity is called " warming changes little source of sound ".

When the sound of indoor be due to warming change little source of sound send, the testing result of electric for Jiao type infrared ray sensor 17 is divided into multiple stage, judges the activity of indoor occupant accordingly with the stage, control air conditioner 1.

In addition, when the sound of indoor be due to warming change large source of sound send, if the amount of sound is larger, then be judged as movable active, when warming changes little source of sound, according to the activity of the indoor occupant that the testing result based on the electric type infrared ray sensor 17 of Jiao is judged, be judged as YES large activity and control air conditioner 1.

Like this, according to the testing result of sound transducer 19, the source of sound of indoor is divided into warming and changes the set that the set of little source of sound and warming change large source of sound, the activity of indoor occupant can be subdivided into more differentiation, by finer control, while consider comfortableness, the effect of economize on electricity can be produced.

In addition, little source of sound is changed as warming, as mentioned above, the set of the apparatus for receiving broadcasting groups such as air conditioner self, TV, radio can be considered, warming as the motion along with indoor occupant changes large source of sound, except the session that indoor occupant self is mutual, it is also conceivable to the set of the beauty appliance such as the cooking apparatus such as dust catcher, body-building apparatus, juice extractor, mixer, hair-dryer, electric saver carrying out housework etc.

In this case, air conditioner self, session are independent sources of sound, but the convenience in order to illustrate, air conditioner self, session are also expressed as group.

The set that these warmings change large source of sound has motor in inside usually, supports the strength, speed etc. of user.Wherein, heavy housework device cluster such as dust catcher, body-building apparatus etc. for the strength needing user, user self also will pay a large amount of activities, and the duration is also long.

Conveniently, the device cluster beyond the device cluster of a large amount of activities of user and above-mentioned source of sound group that do not need beyond heavy housework device cluster is called light housework device cluster.

Like this, air conditioner self and apparatus for receiving broadcasting group are changed the set of little source of sound as warming, heavy housework device cluster and light housework device cluster are changed the set of large source of sound as warming, according to the testing result of sound transducer 19, judge the group of indoor source of sound, can according to the group of the source of sound judged, source of sound is divided into warming and changes the set that the set of little source of sound and warming change large source of sound, the activity of indoor occupant is subdivided into more differentiation, by finer control, can consider that comfortableness produces the effect of economize on electricity.

Thus, known the voice signal received by sound transducer 19 is divided into multiple frequency band, evaluate according to the interval etc. of suitable index to the size of the sound of each frequency band, continuity, scrambling, systematicness, interruption, the kind of source of sound can be inferred with less expensive, simple method.

Figure 21 and Figure 22 is used to be described simply.Figure 21 and Figure 22 is the frequency analysis example of indoor sound, Figure 21 (a) is the frequency analysis example of the sound of air conditioner, Figure 21 (b) is the frequency analysis example of the sound of dust catcher, Figure 22 (a) is the frequency analysis example of ambient noise, and Figure 22 (b) is the frequency analysis example of the sound of TV.

As the example of the sound of the activity along with indoor occupant, the sound (heavy housework device cluster) of known Figure 21 (b) dust catcher is not the sound all comprised from low to high.

The example of the known sound as the activity along with indoor occupant, the sound (session) of the people shown in Figure 22 (a), the sound of high frequency is few, and the sound of the low frequency near 11kHz is more pleasing to the ear than other parts and many.

In addition, the also known sound (heavy housework device cluster) hearing dust catcher continuously, the sound of people has irregular interruption.

The example of the known sound had nothing to do as the activity with indoor occupant, the sound of the usual low frequency of sound of the air conditioner shown in Figure 21 (a) self and the sound of high frequency all little.

As the example of the sound that the activity with indoor occupant has nothing to do, the sound (apparatus for receiving broadcasting group) of the TV shown in known Figure 22 (b) is except comprising the sound of the low frequency suitable with the frequency band of the sound of people (1kHz ~ 4kHz), also comprise the sound of high frequency, the sound of the high frequency of more than 4kHz is much more a lot of than the sound (with reference to Figure 22 (a)) of people.

At this, the feature of each source of sound group is compared, tries to differentiate.Under the state not along with the sound of the activity of indoor occupant, even if the sound (sound of the sound of such as wall clock, the water circulating pump of aquarium, the sound etc. of air conditioner self) also sent in unmanned indoor detected, the size of indoor sound is minimum.

In this case, the sound of low frequency and the sound of high frequency are also essentially continuously as low level, and become regular result.

Thus, in the result by the sound in sound transducer 19 sensing chamber less than the level of regulation, and regularly in continuous print situation, the group of source of sound is judged as " air conditioner self ".

Then, when indoor occupant uses dust catcher to carry out cleaning etc. to indoor, the sound that indoor sound both can't hear session also can't hear the sound of TV, only hears the sound of dust catcher.

In this case, the sound of low frequency and the sound of high frequency are also essentially continuously as high level, and are the regular results almost not having the change of level.

Thus, be more than the level of regulation by the result of the sound in sound transducer 19 sensing chamber, with under roughly the same level regularly continuous print situation, the group of source of sound be judged as " heavy housework device cluster ".

Then, when conversating between the situation, indoor occupant of indoor occupant appreciation TV, radio etc., the session of people has scrambling, and in addition, the sound of general low frequency is many, and then has very long interruption.Thus, can distinguish with the sound of above-mentioned " air conditioner self ", " heavy housework device cluster ".

At this, " session " that source of sound is reality between TV, radio etc. " apparatus for receiving broadcasting group " or indoor occupant is judged, is also difficult to differentiate out even if be conceived to low-frequency band.But in the broadcast, different from session, situation reticent is continuously for a long time few, in addition, due to advertisement, audio etc. that midway adds, the sound of the high frequency do not had in reality " session " can be added in.

By combining these features, " apparatus for receiving broadcasting group " and " session " can be differentiated.

According to above discriminating step, " air conditioner self ", " heavy housework device cluster ", " apparatus for receiving broadcasting group " or the sound that is not identified as " session " are distinguished with " light housework device cluster ".

The structure > of < sound transducer

Like this, be separated at each frequency band the signal that detected by sound transducer 19 and extract out, and using it for judgement.Use Figure 23 that the structure of sound transducer 19 is described.Figure 23 is that source of sound judges block diagram.

Indoor voice signal is captured by sound transducer 19, i.e. microphone 408, and is transformed to the signal of telecommunication.

The voice signal detected is small signal, therefore need to amplify, but as air conditioner 1, needing large power and then have in the product of circuit of the high-frequency drive such as converter circuit, switching power circuit, power supply noise, switching noise are also larger, therefore, noise easily overlaps onto in voice signal, if amplified as former state, then and the problem of amplifying under having overlapping noisy state.

Therefore, in the present embodiment, the substrate identical with amplifier arranges the installation site of microphone 408, and the high-pass filter (HPF400) (such as make more than the 100kHz of 2 doubling times of the frequency 50kHz of source power supply by) arranging the frequency removing power supply noise higher than source power supply near microphone 408 and the high frequency removing low pass filter (LPF) 401 (such as shielding the frequency of more than 15kHz) shielding unwanted high frequency band when judging source of sound, carry out restraint speckle.

In addition, LPF401 is made up of operational amplifier, plays function as the amplifier amplified the voice signal detected by microphone 408.

The voice signal that have passed HPF400 and LPF401 is imported into the multiple filter circuits be made up of differential circuit or the integrating circuit based on operational amplifier.In addition, by use operational amplifier, can with filtering is carried out to voice signal while amplify, therefore, it is possible to reduce number of components, amplify by stages with operational amplifier, therefore, it is possible to improve noiseproof feature, dispersion deflection voltage.

In addition, in the present embodiment, by doubling as filter circuit and amplifier with based on the differential circuit of operational amplifier or integrating circuit, thus form at an easy rate, but also can be configured to arrange filter circuit and amplifier respectively, interwoven crystal pipe and active component reduce amplifier, or use general audio-frequency amplifier to amplifier.In addition, for filter circuit, also can be digital filter, the RC integrator based on resistance and capacitor, the RCL passive filter being combined with inductance, capacitor and resistance and general digital-filter IC so be arranged on APU A/D converter in carry out Fourier transform etc., form filter circuit accordingly with the situation of cost, peripheral components etc., do not limit the device of amplifier and filter circuit.

In the present embodiment, be configured to voice signal is divided into 2 frequency bands.

One is be made up of differential circuit 402 and integrating circuit 403, the bandpass filter (BPF) 404 (such as making 1kHz ~ 4kHz pass through) that the low-frequency band of the frequency band of the sound close to people is passed through.

Another is made up of differential circuit 405, the high-pass filter (HPF) 406 (such as making more than 5kHz pass through) that the high frequency band that the sound people making the mechanical sounds such as dust catcher such cannot send passes through.

In addition, data signal is transformed in the comparator 407 that the output in these each filter circuits (BPF404, HPF406) possesses in rear class.Like this, be configured to by microphone 408, filter circuit (HPF400, LPF401, BPF404, HPF406), amplifier (operational amplifier) and even comparator 407 are installed on the same substrate, the data signal of two systems after being converted by comparator 407 is outputted to control assembly 10, carrys out restraint speckle.

In addition, when being amplified by operational amplifier, if produce noise on the power line of operational amplifier, then magnification change, occurs as noise in voice signal.Therefore, the electrolytic capacitor (not shown) for suppressing power supply noise also can be set on the same substrate, make supply to the power good of the operational amplifier of filter circuit.

In addition, by the threshold value being transformed to data signal by comparator 407 being set only cannot be surmounted by the operating sound of air conditioner 1, the operating sound due to air conditioner self can being prevented and malfunction, being configured to only be input to control assembly 10 when have input the voice signal from external sound source.

In addition, in the present embodiment, as mentioned above, be configured to voice signal is divided into 2 frequency bands, but also can with the number of object of the object detected, detection, substrate installing space, cost in combination, the change of frequency band, multiple filter circuit are set, this structure are not limited.

In addition, in the present embodiment, also can be configured to the voice signal detected in combination, light display lamp (with reference to Fig. 1).Thereby, it is possible to make user identify that microphone 408 detects the situation of voice signal by vision.In addition, also have following such advantage, namely when the peripheral circuits such as contingency microphone 408, filter circuit there occurs fault, repair operation person easily can confirm fault.In addition, in the fault due to above-mentioned microphone 408, amplifying circuit etc., be taken into voice signal in control assembly 10 (activity decision means 41) very little or few when, the buzzer (not shown) that air conditioner 1 is possessed is blowed, according to the result this buzzer sound being detected, can detect the exception of the peripheral circuits such as microphone 408, amplifier, repair operation person can easily confirm.

< source of sound determination methods >

Then, use Figure 24, the source of sound determination methods that activity decision means 41 performs is described.

In step S101, activity decision means 41 performs sampled voice.

Specifically, the sound of indoor is separated into the sound (such as 1kHz ~ 4kHz) of low-frequency band, the sound (such as 5kHz) of high frequency band extracting out by sound transducer 19.

In addition, for each frequency band, carry out the sampling of stipulated time according to the sampling period of regulation, calculate the ratio (HP) detecting number of times of the sound in the ratio (BP) detecting number of times of the sound in low-frequency band, high frequency band, as the sampled result of 1 time.Repeatedly (m time) carry out this sampling, obtain sampled result BP ₁~ BP _m, HP ₁~ HP _m.

In addition, in following judgement, according to sampled result (BP ₁~ BP _m, HP ₁~ HP _m) the level of size to sound judge.

In addition, according to whole sampled result (BP ₁~ BP _m, HP ₁~ HP _m) whether be positioned at the side of the determined defined threshold of each source of sound group to judge the continuity of sound.

According to sampled result (BP ₁~ BP _m, HP ₁~ HP _m) the upper limit, lower limit and sampled result (BP ₁~ BP _m, HP ₁~ HP _m) mean value between difference whether be positioned at the judgement amplitude to the regulation that each source of sound group determines within, judge the systematicness of sound.

According to sampled result (BP ₁~ BP _m, HP ₁~ HP _m) be to the judgment threshold of the regulation that each source of sound group determines more than number of times be whether more than lower limit frequency threshold value to the regulation that each source of sound group determines and be below upper limit frequency threshold value and then be whether the interrupting in midway in succession of number of times of more than judgment threshold, judge the scrambling of sound.

In addition, according to sampled result (BP ₁~ BP _m, HP ₁~ HP _m) be to the threshold value of the regulation that each source of sound group determines more than number of times be below set upper limit frequency threshold value that each source of sound group is determined and be the number of times of more than threshold value whether midway is interrupted and sampled result (BP in succession ₁~ BP _m, HP ₁~ HP _m) the upper limit, lower limit and sampled result (BP ₁~ BP _m, HP ₁~ HP _m) mean value between difference whether exceeded judgement amplitude threshold to the regulation that each source of sound group determines, judge whether sound has longer interruption.

In addition, in the following description, if the sampled result (BP in low-frequency band ₁~ BP _m) mean value be BP _meanif, the sampled result (BP in low-frequency band ₁~ BP _m) maximum be BP _maxif, the sampled result (BP in low-frequency band ₁~ BP _m) minimum of a value be BP _minif, the sampled result (HP in high frequency band ₁~ HP _m) mean value be HP _meanif, the sampled result (HP in high frequency band ₁~ HP _m) maximum be HP _maxif, the sampled result (HP in high frequency band ₁~ HP _m) minimum of a value be HP _min.

In step s 102, activity decision means 41 judges whether source of sound is " air conditioner self ".Specifically, at sampled result (BP ₁~ BP _m, HP ₁~ HP _m) size in whole sampling period less than air conditioner judgment threshold (BP _a, HP _a) when, the kind of source of sound is judged as " air conditioner self ".

When meeting above-mentioned Rule of judgment in step s 102, proceed to step S103, activity decision means 41 judges that source of sound is " air conditioner self ".On the other hand, when not meeting above-mentioned Rule of judgment, step S104 is proceeded to.

In step S104, activity decision means 41 judges whether source of sound is " heavy housework device cluster ".Specifically, at sampled result (BP ₁~ BP _m, HP ₁~ HP _m) size be housework device cluster judgment threshold (BP in whole sampling period _h, HP _h) more than, the mean value (BP of sampled result _mean, HP _mean) and the minimum of a value (BPmin, HPmin) of sampled result between difference judge amplitude (BW at housework device cluster _c, HWc) within, the maximum (BP of sampled result _max, HP _max) with the mean value (BP of sampled result _mean, HP _mean) between difference judge amplitude (BW at housework device cluster _c, HW _c) within when, the kind of source of sound is judged as " housework device cluster ".

When meeting above-mentioned Rule of judgment in step S104, proceed to step S105, source of sound is judged as by activity decision means 41 " heavy housework device cluster ".On the other hand, when not meeting above-mentioned Rule of judgment, step S106 is proceeded to.

In step s 106, activity decision means 41 judges whether source of sound is " apparatus for receiving broadcasting group ".Specifically, at sampled result (BP ₁~ BP _m, HP ₁~ HP _m) be apparatus for receiving broadcasting judgment threshold (BP _t, HP _t) more than number of times be the lower limit frequency threshold value (BL of apparatus for receiving broadcasting group _t, HL _t) more than and be upper limit frequency threshold value (BH _t, HH _t) below, and then be apparatus for receiving broadcasting judgment threshold (BP _t, HP _t) more than in succession on the way in discontinued situation of number of times, the kind of source of sound is judged as " apparatus for receiving broadcasting group ".

When not meeting above-mentioned Rule of judgment in step s 106, proceed to step S107, source of sound is judged as " apparatus for receiving broadcasting group " by activity decision means 41.On the other hand, when not meeting above-mentioned Rule of judgment, step S108 is proceeded to.

In step S108, activity decision means 41 judges whether source of sound is in " session ".Specifically, at sampled result (BP ₁~ BP _m, HP ₁~ HP _m) be session judgment threshold (BP _s, HP _s) more than number of times be the lower limit frequency threshold value (BL of session _s, HL _s) more than and be upper limit frequency threshold value (BH _s, HH _s) below, and then be session judgment threshold (BP _s, HP _s) more than number of times in succession midway discontinued situation under, the kind of source of sound is judged as " session ".

When meeting above-mentioned Rule of judgment in step S108, proceed to step S109, source of sound is judged as " session " by activity decision means 41.

On the other hand, when not meeting above-mentioned Rule of judgment, proceed to step S110, source of sound is judged as by activity decision means 41 " light housework device cluster ".In addition, if the sound of session is large, one's voice in speech ceaselessly continues, then be not judged as session, but under these circumstances, the activity of the people conversated also increases, and becomes the activity with the situation same degree using the light housework device cluster such as cooking apparatus, beauty appliance, affairs equipment, therefore, in the control of air conditioner 1, regard as and employ light housework device cluster.

Then, use Figure 25, the correction in the judgment threshold judging according to sampled result the basis of source of sound plays a significant role (each threshold value used in S102, S104, S106, S108) is described.Figure 25 is the figure of the correction that the judgment threshold carried out due to ambient sound is described.

In indoor, even if when indoor occupant is quiet, also have the various sound such as the sound of the water pump of clock and watch, aquarium, when air conditioner 1 will be controlled by sound transducer 19, must consider be combined with indoor occupant quiet time sound and the sound of air conditioner self and the impact of sound that obtains.Therefore, in the air conditioner 1 of the present embodiment, when starting running, sound when judging that indoor occupant is quiet according to the flow process shown in Figure 24.

When operating at first at the machine of installing an air-conditioner 1, if this running operates first, then running or stopping under the state of solemn silence, measure in (being started running under the state such as in solemn silence 1 minute) during the reference atmosphere sound measurement of measuring basis ambient sound by sound transducer 19, the initial value be stored in each time period in the storage device (not shown) of air conditioner 1 is substituted into as a reference value.

At this moment sampled result is on average named as initial value, compares with a reference value determined air conditioner self (roughly consistent with the mean value of sampled result when operating under same environment).

When the result compared be a reference value less than initial value, when the judged result of source of sound is air conditioner self (with reference to step S103), even if indoor are quiet, the ambient sound of the indoor beyond the sound being also thought of as air conditioner self creates impact to result, and revises the judgment threshold of each source of sound.

When the judged result of source of sound is the source of sound group beyond air conditioner self, is judged as it not being air conditioner self and the such significant sound of ambient sound, does not carry out the correction of the judgment threshold of each source of sound.When the result compared initial value and a reference value be a reference value is more than initial value, fully can identifies according to current judgment threshold and judge each source of sound, therefore not carrying out the correction of the judgment threshold of each source of sound.

Like this, the air conditioner 1 of the present embodiment has threshold value correcting part (not shown), this threshold value correcting part is according to the testing result of sound transducer 19, the source of sound kind judgment threshold of the kind judging source of sound is set, the indoor of air conditioner 1 (indoor set 2) are being installed, with operate under the state of solemn silence or to stop and by the measurement result (initial value) of the sound transducer 19 in during the reference atmosphere sound measurement of sound transducer 19 measuring basis ambient sound accordingly, correction judgment threshold.Activity decision means 41 is with by threshold value correcting part (not shown) revised judgment threshold accordingly, judge the kind of source of sound, with the testing result of the kind of the source of sound judged and Jiao's electricity type infrared ray sensor 17 accordingly, judge the activity of indoor occupant.

Then, the action of burnt electric type infrared ray sensor 17 is described.

Burnt electric type infrared ray sensor 17, together with Fresnel Lenses 17a, catches the change of the ultrared amount from indoor.When having active motion in indoor, its reacting dose is large, and when undisturbedly moving, reacting dose is little.Utilize these, by the bandpass filter (not shown) of the movement of extracting people out, the signal from the electric type infrared ray sensor 17 of Jiao is amplified, carry out digitlization by comparator (not shown), and be delivered to control assembly 10 (activity decision means 41).

Activity decision means 41 is under the sampling period (such as 10ms) of regulation, during sampling interval (such as 60 seconds), data signal from this burnt electric type infrared ray sensor 17 is sampled, reaction in the data of calculating sampling detects the ratio of data, obtains reaction and detects ratio Px.

Detecting ratio Px less than for differentiating the amount of indoor motion whether little quiet judgment threshold Pb in this reaction, the detection zone of reaction being divided and is divided into " reaction: quiet ".

Then, detect ratio Px and, when differentiating whether large more than the motion determination threshold value Pv of the amount of indoor motion, the detection zone of reaction is divided and is divided into " reaction: strong " when reacting.

When react detect ratio Px be quiet more than judgment threshold Pb, less than motion determination threshold value Pv, the detection zone of reaction divided be divided into " reaction: in ".

Then, use Figure 26, illustrate and by the combination of the electric type infrared ray sensor 17 of Jiao and sound transducer 19, activity is segmented and the method that judges.Figure 26 is the figure illustrating that combined moving amount judges.

Activity decision means 41 combines to be distinguished (quiet, strong, in) based on the reaction detection of the detection signal of Jiao's electric type infrared ray sensor 17, judges the result of (air conditioner self, heavy housework device cluster, apparatus for receiving broadcasting group, session, light housework device cluster) based on the source of sound of the detection signal of sound transducer 19, as shown in figure 26, the activity of indoor occupant is segmented.

In addition, in fig. 26, the situation of air conditioner self, apparatus for receiving broadcasting group (TV) is changed little source of sound set as warming, using weigh housework device cluster (dust catcher), session, light housework device cluster (other) situation change large source of sound set as warming.

Like this, even if distinguish identical based on the reaction detection of the detection signal of Jiao's electric type infrared ray sensor 17, when changing large source of sound set along with the warming of the activity of indoor occupant at source of sound, be that the warming had nothing to do with the activity of indoor occupant changes compared with the situation of little source of sound set with source of sound, activity is judged larger.

Thus, the differentiation of activity from before three phases become 5 ~ 6 stages, controlled more meticulously compared with in the past so can become.

In the example of Figure 26, if it is " reaction: strong " that the reaction of burnt electric type infrared ray sensor 17 detects differentiation, the activity that the kind of source of sound changes the situation of large source of sound set by the warming that heavily housework device cluster, session and light housework device cluster form is maximum.In addition, for minimum activity, if it is " reaction: quiet " that the reaction of burnt electric type infrared ray sensor 17 detects differentiation, when the warming that source of sound is made up of air conditioner self and apparatus for receiving broadcasting group changes little source of sound set, activity is minimum.

In addition, for activity, when the reaction of Jiao's electric type infrared ray sensor 17 detect distinguish identical, determine that the activity that activity makes warming change little source of sound set is that warming changes more than the activity of large source of sound set.In addition, when the source of sound set of sound transducer 19 is identical, the relation of the < that determines that activity makes to become " reaction: quiet " " reaction: in " < " reaction: strong ".

When the cooling operation of air conditioner 1, when the activity of indoor occupant is little, be the quiet and sluggish state of metabolism of indoor occupant, body internal heat generation is few, and the temperature sensation of indoor occupant changes to cold side.Therefore, even if improve room temperature a little, comfortableness, also in the scope of allowing, can carry out energy-saving operation in the scope improving room temperature a little.

In addition, when the warming operation of air conditioner 1, when the activity of indoor occupant is large, be the state that indoor occupant moves actively and metabolism is active, body internal heat generation is large, and the warm sensation of indoor occupant is also changed to hot side, therefore, even if reduce room temperature a little, comfortableness, also in the scope of allowing, can carry out energy-saving operation with the amount reducing room temperature a little accordingly.

The activity that activity decision means 41 is judged is sent to temperature drift value set parts 42, temperature drift value set parts 42 according to the activity judged by activity decision means 41, design temperature deviant.In addition, target temperature is set by target temperature set parts 44 according to temperature drift value.In addition, control compressor 51, indoor blower 52, outdoor draft fan 53 by air conditioning capacity control assembly 45, make intake air temperature (temperature detected by temperature sensor 11) close to target temperature.

Like this, in the present embodiment, except the electric type infrared ray sensor 17 of Jiao, sound transducer 19 is also utilized to judge activity in more detail, according to the activity setting target temperature judged, therefore, it is possible to provide the state (active state) combined with indoor occupant, air conditioner 1 energy-conservation while considering comfortableness.
