The structure of anterior up-down wind direction board 291 then, is described.Figure 12 is the details drawing of anterior up-down wind direction board 291.

The anterior up-down wind direction board 291 of present embodiment comprises: the transparent component 291a that is formed by transparent material, the opaque member 291b with the size in the projected area that is contained in this transparent component 291a.In addition, transparent component 291a is formed from the leading section side of anterior up-down wind direction board 291 and stretches significantly and form.

Promptly; The opaque member 291b of present embodiment is formed on the arm 291c that when an end side of depth direction tilts, extends in the both sides of the basal part 291c of the thin shape with depth dimensions d3 with central authorities, 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 that disposes abreast with basal part 291c.

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

That is, transparent component 291a is divided into 2 parts at degree of depth wind direction with rear side, and the arm 291e side that becomes rotation shaft side is carried out back up, has formed pellucidly that to become another of front with respect to anterior up-down wind direction board rotating shaft 291f distolateral.Thus, can't see unwanted in appearance opaque member 291b, can make the leading section of anterior up-down wind direction board 291 transparent on the other hand, therefore, improved aesthetic appearance, and can alleviate the constriction that action brought of anterior up-down wind direction board 291.For example, the opaque processing unit 9 of transparent component 291a (part that contacts with opaque member 291b) can cover, feasible shaft portion (anterior up-down wind direction board rotating shaft 291f) that can't see the anterior up-down wind direction board 291 of support etc.In addition, can make and can't see attachment features such as burnt electric type infrared ray sensor 17, radiation sensor 18, sound transducer 19.

Figure 13 is the side view of the mounting portion of the sound transducer 19 when closing anterior up-down wind direction board 291.That kind 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 that covers front side air inhalation part 270`.Therefore, under the state that this front portion up-down wind direction board 291 is received, because that the leading section of anterior up-down wind direction board 291 is formed is transparent, so the user can see the part of upholstery face 24 across this transparent part.In the present embodiment, no matter under the operating condition or the halted state that turns round, on the upholstery face 24 that the user can see, form the inside display unit 22 that shows operating condition bandedly.In addition, burnt electric type infrared ray sensor 17, radiation sensor 18 and the sound transducer 19 that moves during running is configured in the dorsal part of the upholstery face 24 that is blocked by anterior up-down wind direction board 291.

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

That kind shown in figure 14; When closing anterior up-down wind direction board 291; The top (with reference to Figure 12) of transparent component 291a through anterior up-down wind direction board 291, display window 22b (with reference to Fig. 9), show opening 22a (with reference to Fig. 9), display lamp 397a that can identification sensor module 16 (with reference to Fig. 9) lights (with reference to Fig. 9)/extinguishes, therefore; Can keep the Presentation Function of display unit 397, transmit appropriate information to the user.In addition; Closing anterior up-down wind direction board 291 constantly; Be not limited to the moment that the running of air conditioner 1 stops, it is low for example to begin the temperature of back indoor heat converter 33 at warming operation sometimes, carries out the waste heat running of indoor heat converter 33 accordingly with the running of indoor Air Blast fan 311.In this case, the purport (for example demonstration) that on display unit 397, shows the waste heat running so that the user can discern according to position, the color of the display lamp 397a that lights.In addition, when closing anterior up-down wind direction board 291,, become succinct outward appearance at the indoor peristome (burnt electrical aperture 24c, radiation opening 24d, intercommunicating pore 24b) that can't see burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19.

Shown in figure 15, when opening anterior up-down wind direction board 291, the display window 22b of inner display unit 22 exposes, and display lamp 397a (with reference to Fig. 9) that can identification sensor module 16 (with reference to Fig. 9) lights/extinguishes.In addition; Open the anterior up-down wind direction board 291 of the peristome (burnt electrical aperture 24c, radiation opening 24d, intercommunicating pore 24b) that covered burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19 and indoor living space, can bring into play the function of each sensor.

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

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; Cover burnt electric type infrared ray sensor 17, radiation sensor 18 and sound transducer 19 with blocking member (opaque member 291b), can become does not have unnecessary concavo-convex succinct outward appearance, can not destroy the atmosphere of interior decoration.

In addition, owing to being used as, the part with anterior up-down wind direction board 291 blocks member (opaque member 291b), so do not need special-purpose blocking member and block the member drives parts.

In addition, inner display unit 22 is covered by transparent component 291a, but when running stops; Anterior up-down wind direction board 291 erects subvertical angle and makes and be suitable for framework 20, therefore, and when on-wall type air conditioner 1 that kind is seen from bottom to top; Only when the display lamp 397a of sensor assembly 16 did not light, the reflection on the surface of transparent component 291a produced influence more by force, can't see the inside display unit 22 at its back; Can become succinct outward appearance, can not destroy the atmosphere of interior decoration.

In addition, even under the state of closing anterior up-down wind direction board 291, if light the display lamp 397a of sensor assembly 16; Can confirm that then running shows; Therefore, in order to begin to prevent cold wind when waiting at warming operation, till rising to the temperature of indoor heat converter 33; Close anterior up-down wind direction board 291 always, in the also out-of-operation warming up process of indoor Air Blast fan 311, also can correctly confirm operating condition.

< filter cleaning mechanism >

Then, use Figure 16, Figure 17, the cleaning agency of filter 231,231` is described.Figure 16 is the figure that sees filter cleaning agency 230 from the upper face side of indoor set 2, and Figure 17 (a) is the stereogram of filter cleaning mechanism 230, (b) is the stereogram that only demonstrates hairbrush.

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

On two faces of the upside air inhalation part 270 (with reference to Fig. 2) at the upper reaches of indoor heat converter 33 (with reference to Fig. 2) and front side air inhalation part 270` (with reference to Fig. 2), be provided with plane filter 231,231`.Filter 231,231` link to each other with guide housing 234, and guide housing 234 possesses track 235,235` at upside rear portion and preceding side lower part, possess cardan shaft 243 at the cross section of filter 231,231`.

Cardan shaft 243 has polygonal cross section, is set at the bearings on the guide housing 234, via the gear that is installed on the end that has connected one-sided bearing 245, be fixed on guide housing 234 on mobilely be connected with motor 242.Loosely is equipped with screw 244, carriage 261 on cardan shaft 243, and screw 244 is set at guide housing 234, with cardan shaft 243 abreast with shelf (rack) 237 interlocks.

Between carriage 261 and track 235,235`, stride across filter 231,231` respectively and set up hairbrush carriage 262,262`, at hairbrush carriage 262, last hairbrush 267, the 267` that filter 231,231` are cleaned that be equipped with of 262`.

Move with motor 242 rotations through making, cardan shaft 243, screw 244 rotations, screw 244 moves at left and right directions along shelf 237 and the direction of rotation that moves with motor 242 accordingly, and carriage 261 is moved.Thus, Yi Bian hairbrush 267,267` moves and on one side wipe to connect and clean with filter 231,231`, filter 231, the last dust of 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 attached to the last dust of hairbrush 267,267` and hold.In addition, also be to be used to make hairbrush 267,267` to clean and be to clean the hairbrush 267 of preparing, the cleaning part of 267` next time.

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

Possess the standby parts that hairbrush 267 carries out standby when not cleaning action on filter 231 right-hand.

When cleaning action, make scanner 232 (with reference to Figure 17) action, the hairbrush 267 (A of Figure 18) of standby in the standby parts is moved from right to left, make this hairbrush 267 scan filter 231 (with reference to the C of Figure 18).At this; The hair end of hairbrush 267 is with respect in the standby parts, becoming open state (with reference to the A of Figure 18); From the standby parts when filter 231 moves; Relative component changes and contacts when the hair end is out of shape on one side therewith owing to tilting and on the face of filter 231, wipes reliably with filter 231 to connect.In addition, B is described in the back.

Hairbrush 267 moves on the direction of dust-collection element 280 on one side, Yi Bian scan filter 231, cleaning dust 236 (with reference to the C of Figure 18).Be through with the hairbrush that scans 267 of filter 231 with the D part of the dust of having cleared away 236 through Figure 18, transfer to dust-collection element 280, remove dust 236, the dust 236 that is removed is accommodated in the dust-collection element 280, hairbrush 267 cleaning that becomes.Then, do not wipe the mode that connects with filter 231 with the hair end of hairbrush 267, the standby parts of dust-collection element 280 to the right move (with reference to the B of Figure 18) to hairbrush 267 from the left side.

In addition; Explained and to have scanned filter 231 and dust after removing is contained in the action in the dust-collection element 280 with hairbrush 267; But will with hairbrush 267` scan filter 231` and the dust removed be contained among the dust-collection element 280` situation too, omit explanation.

Through the filter cleaning mechanism 230 of such filter 231,231` is installed; For example can filter cleaning mechanism 230 be turned round automatically; Filter 231,231` are cleaned; Can in filter 231,231`, too not retain dust, the anti-possible trouble that terminates in of the surge phenomenon of the indoor Air Blast fan 311 that can cause when in filter 231,231`, too retaining dust.

Like this; The air conditioner 1 of present embodiment is through mounting filtering device cleaning agency 230; Can prevent the surge phenomenon of indoor Air Blast fan 311, can correctly detect indoor sound by the sound transducer 19 that is used for the sound of (in the conditioned space) in the sensing chamber, so; For inferring the purposes that the activity of indoor occupant is turned round and controlled, be the structure that is fit to according to indoor sound.

" control of air conditioner "

Then, use Figure 19, the summary of control of the air conditioner 1 of 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 from the information of various sensors, from the indication of remote controller 5 accordingly, control indoor set 2, off-premises station 6.Through 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.; To be taken into microcomputer (not shown) from indoor 900 information to the inside of control assembly 10; According to various result of calculations, control air conditioner 1.

Temperature sensor 11 be set at front side air inhalation part 270` (with reference to Fig. 2) near, detect the temperature (being called " intake air temperature ") that is drawn into the room air of indoor set 2 from air suction inlet 27.

Humidity sensor 12 be set at front side air inhalation part 270` (with reference to Fig. 2) near, detect from be drawn into the humidity of the room air of indoor set 2 from air suction inlet 27.

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

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 ability control assembly 45.

Activity decision means 41 has following function: according to the information of electric type infrared ray sensor 17 of Jiao and sound transducer 19; As the right side institute example of Figure 20, divide several stages the activity of indoor occupant is distinguished and to be judged, and be delivered to temperature drift value set parts 42.

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

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

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

Air-conditioning ability control assembly 45 is according to from the target temperature of target temperature set parts 44, from the intake air temperature information of temperature sensor 11 etc.; Set compressor rotary speed, indoor blower rotating speed, outdoor draft fan rotating speed through 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, detects the temperature (intake air temperature) of the suction air that is inhaled into air conditioner 1 by temperature sensor 11, becomes the mode of the target temperature of being set by target temperature set parts 44 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, carry out the adjustment of air conditioner 1 thus.

At this moment; With the setting room temperature of setting by temperature sensor 11 detected intake air temperatures, 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 it is high to the temperature of the living space of the height and position of face that the known intake air temperature that is installed in the air conditioner 1 (indoor set 2) of indoor eminence compares from the indoor ground at indoor occupant place; In order to revise this temperature difference, the back design temperature that appends that unnecessary setting room temperature has been appended behind the setting (temperature drift value) that is calculated by deviant set parts 42 is set at target temperature, and control air conditioner 1 makes intake air temperature near target temperature.

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

" the activity determination methods of indoor occupant "

Then, explain 41 that judge by the activity decision means, made up burnt electric type infrared ray sensor 17 and sound transducer 19 and method that the activity refinement ground of indoor occupant is judged.Figure 20 is the table of the relation of expression activity description and activity.

The influence that the warm sensation of known person receives temperature, humidity, air-flow, radiation, clothing amount and activity.Temperature (and humidity) in air conditioner 1 control room; Make and keep comfortableness; If but the action of indoor occupant (activity) is when changing, even identical in other conditions, this people's warm sensation also can change; In order to keep comfortableness, require to change temperature (and humidity) etc. accordingly with this people's action.Corresponding for therewith; The burnt electric type infrared ray sensor 17 of air conditioner 1 combination and the sound transducer 19 of present embodiment are obtained the active state of indoor occupant, when considering the comfortableness of indoor occupant with carrying out refinement; Control extremely carefully, carry out energy-saving operation.

In the past, used burnt electric type infrared ray sensor 17 to detect the activity of indoor occupants, when activity is big, regulated room temperature low, at activity hour with room temperature regulate highly technology practicability.But; Personnel's the activity in the multistage ground divided chamber for only using burnt electric type infrared ray sensor 17; Because the sensitivity of sensor is for detecting error, lower towards the motion of the direction of sensor; So it is difficult not increasing the number of burnt electric type infrared ray sensor, improved the cost of air conditioner 1.

In addition, in that electric type infrared ray sensor 17 has carried out under the situation of people's detection by Jiao, if indoor occupant moves, then the output of sensor changes, and can detect moving of indoor occupant.Under the situation that does not have to move at indoor occupant; Because the output of sensor does not change; Do not move so can detect indoor occupant, but, be to have the activity refinement ground of what degree to judge to indoor occupant just according to mobile the having or not of indoor occupant.

In addition, following such method is arranged, promptly judge the activity of indoor occupant for refinement ground; The electric type infrared ray sensor of a plurality of Jiao is set; At indoor occupant arranged significantly when moving, the electric type infrared ray sensor of a plurality of Jiao reacts, moving hour of indoor occupant; Have only a sensor to react, differentiate activity large and small of indoor occupant thus.

But, in the method, need the electric type infrared ray sensor of a plurality of Jiao, become the reason that cost improves.In addition, even the electric type infrared ray sensor of a plurality of Jiao is being arranged, but the mobile ratio sensor of indoor occupant can be detected moves under the little situation, under the situation of carrying out identical action, the problem that can't judge activity arranged.

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

In the left side of Figure 20, as comparative example, the example of dividing into of the activity when only having used burnt electric type infrared ray sensor 17 is put down in writing.Like this, under the situation of only having used 1 electric type infrared ray sensor 17 of Jiao, even roughly according to 3 large, medium and small differentiations of distinguishing further segmentation activity, page or leaf is owing to the reason of above-mentioned that kind, and precision is insufficient.

On the right side of Figure 20, put down in writing combination and used the burnt electric type infrared ray sensor 17 of present embodiment and the example that sound transducer 19 is distinguished the situation of activity.According to present embodiment, can distinguish activity with segmenting, therefore, consider comfortableness according to the air-conditioning of the activity that is suitable for indoor occupant, can carry out energy-saving operation.

< having used the judgement of the activity of sound transducer and burnt electric type infrared ray sensor >

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

Have at the sound of the indoor generation of air conditioner 1 running various, have session between the sound, indoor occupant of air conditioner self sound, be accompanied by the indoor occupant sound movable, indoor occupant through the sound equipment such as dust catcher, cooking apparatus, beauty appliance being operated the sound that produces, the sound etc. of water pump of sound, music, audio etc., clock and watch, aquarium when indoor occupant is appreciated TV, radio, sound equipment and also sent etc. even without the people through carrying out clerical operations, tailor, simple arrangement etc.

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

In the sound of handling as " with the irrelevant sound of the activity of indoor occupant "; Even the sound that the sound of the water pump of clock and watch, aquarium etc. also send under unmanned situation is the sound that be used as the environment sound in the room that air conditioner 1 has been installed, the sound and the difference of other sound that need the operating sound of air conditioner self be superposeed.

The sound of the TV that equally, also needs to handle as " with the irrelevant sound of the activity of indoor occupant ", radio, sound appliances, music, audio with and the different conduct of sound of air conditioner self comes with the irrelevant sound of the activity of indoor occupant and other sound are distinguished.Below, TV etc. is called the apparatus for receiving broadcasting crowd.

In addition, under the situation of the dust catcher in using " being accompanied by the sound of the activity of indoor occupant " etc., indoor occupant is also moving actively, therefore, on the basis that the suitable air of needs is in harmonious proportion, need distinguish with other sound.Below, will as dust catcher etc. in use the also moving actively equipment of indoor occupant be called heavy housework and use device cluster.

Equally, need use the sound transducer 19 superfine activities that cause personnel in the ground divided chamber to the session in " being accompanied by the sound of the activity of indoor occupant ".If the sound of session is little; Then can be judged as is the state of undisturbedly having a rest, if session is loud and lasting incessantly, can think neatly that then this people's activity also increases such generality tendency; Therefore, need grasp distinctively with other sound.

Equally; Under use cooking apparatus in " being accompanied by the sound of the activity of indoor occupant ", beauty appliance, the situation of affairs with equipment etc.; Because indoor occupant also uses on one side a little versatilely, thus need with use heavy housework with the situation of device cluster, distinguish in the time of carrying out the rest of session one side with quiet sound on one side.Below, will as cooking apparatus, beauty appliance, affairs with equipment etc. in use indoor occupant also a little the equipment of motion become light housework and use device cluster.

The kind of the source of sound that should differentiate thus, is between " air conditioner self ", TV etc. " apparatus for receiving broadcasting crowd ", dust catcher etc. " heavy housework use device cluster ", cooking apparatus etc. " gently housework is used device cluster " and the indoor occupant " session ".Can't be differentiated the motion and the sound that have intermediateness for their source of sound, therefore be divided into " light housework is used device cluster ".

If the words of the relation of the kind of these sources of sound of observation 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 put down in writing but be 1.0～1.8METs, and air conditioner self does not change the activity of indoor occupant.

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

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

The first, be accompanied by under the situation of movable sound in the indoor occupant activity, because activity is arranged, the variation of the body internal heat generation of indoor occupant increases.Below, the kind of sending the source of sound that is accompanied by this movable sound is called " thalposis changes big source of sound ".

The second, though produce hardly under the situation that is accompanied by movable sound in the activity that indoor personnel are arranged, the variation of body internal heat generation is little.Below, the kind of sending the source of sound that is not accompanied by this movable sound is called " thalposis changes little source of sound ".

At indoor sound is because thalposis changes under the situation that little source of sound sends, and the testing result of the electric type infrared ray sensor 17 of Jiao is divided into a plurality of stages, judges the activity of indoor occupant, control air conditioner 1 accordingly with the stage.

In addition; At indoor sound is because thalposis changes under the situation that big source of sound sends; If the amount of sound is bigger, then be judged as movable enlivening, change at thalposis under the situation of little source of sound; According to the activity of the indoor occupant of judging based on the testing result of the electric type infrared ray sensor 17 of Jiao, being judged as is big activity and control air conditioner 1.

Like this; Testing result according to sound transducer 19; Indoor source of sound is divided into thalposis changes the set of little source of sound and the set that thalposis changes big source of sound, can the activity of indoor occupant be subdivided into more differentiation, through finer control; Can consider comfortableness on one side, produce the effect of economize on electricity on one side.

In addition; Change little source of sound as thalposis; As stated, can consider apparatus for receiving broadcasting crowds' such as air conditioner self, TV, radio set, change big source of sound as the thalposis of the motion that is accompanied by indoor occupant; Except the mutual session of indoor occupant self, it is also conceivable that the set of beauty appliances such as cooking apparatus, hair-dryer, electric saver such as the dust catcher that carries out housework, body-building apparatus, juice extractor, mixer etc.

In this case, air conditioner self, session are independent sources of sound, but the convenience in order to explain also is expressed as the crowd with air conditioner self, session.

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

For ease, heavy housework is called light housework with the device cluster beyond the device cluster of a large amount of activities that do not need the user beyond the device cluster and the above-mentioned source of sound crowd and uses device cluster.

Like this; Air conditioner self and apparatus for receiving broadcasting crowd are changed the set of little source of sound as thalposis, heavy housework is changed the set of big source of sound with device cluster as thalposis with device cluster and light housework, according to the testing result of sound transducer 19; Judge the crowd of indoor source of sound; Can source of sound be divided into thalposis change the set of little source of sound and the set that thalposis changes big source of sound according to the crowd of the source of sound of judging, the activity of indoor occupant is subdivided into more differentiation; Through finer control, produce the effect of economize on electricity while can consider comfortableness.

Thus; Can know and to divide into a plurality of frequency bands by the voice signal that sound transducer 19 receives; According to suitable index the size of the sound of each frequency band, continuity, scrambling, systematicness, the interval of being interrupted etc. are estimated, can be inferred the kind of source of sound with less expensive, simple method.

Use Figure 21 and Figure 22 to describe simply.Figure 21 and Figure 22 are the frequency analysis examples 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, and 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 that is accompanied by indoor occupant, can know that the sound (heavy housework is used device cluster) of Figure 21 (b) dust catcher is not the sound that all comprises from the low frequency to the high frequency.

Can know example as the sound of the activity that is accompanied by indoor occupant, the people's shown in Figure 22 (a) sound (session), the sound of high frequency is few, and near the sound of the low frequency the 11kHz is more pleasing to the ear and many than other parts.

In addition, also can know the sound (heavy housework is used device cluster) of hearing dust catcher continuously, people's sound has irregular being interrupted.

Can know the example of the sound that the conduct and the activity of indoor occupant are irrelevant, the sound of the common low frequency of sound of the air conditioner self shown in Figure 21 (a) and the sound of high frequency are all little.

As with the example of the irrelevant sound of the activity of indoor occupant; The sound (apparatus for receiving broadcasting crowd) that can know the TV shown in Figure 22 (b) is except comprising and the frequency band of people's the sound (sound of suitable low frequency of 1kHz～4kHz); The sound that also comprises high frequency, the sound of the high frequency that 4kHz is above is howed a lot than people's sound (with reference to Figure 22 (a)).

At this, each source of sound crowd's characteristic is compared, try to differentiate.Under the state of the sound of the activity that is not accompanied by indoor occupant, even detect the unmanned indoor sound that also sends (for example the sound of the sound of the water circulating pump of the sound of wall clock, aquarium, air conditioner self etc.), the size of indoor sound is minimum.

In this case, the sound of low frequency and the sound of high frequency are low level by continuous detecting also, and become result clocklike.

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

Then, indoor occupant use dust catcher to indoor situation of cleaning etc. under, 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 high level by continuous detecting also, and are the results who does not clocklike almost have the variation of level.

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

Then, appreciate at indoor occupant between the situation, indoor occupant of TV, radio etc. and carrying out under the situation of session, people's session has scrambling, and in addition, the sound of general low frequency is many, and then very long interruption is arranged.Thus, can distinguish with above-mentioned " air conditioner self ", the sound of " heavy housework is used device cluster ".

At this, be that " session " of the reality between TV, radio etc. " apparatus for receiving broadcasting crowd " or the indoor occupant judged to source of sound, also be difficult to differentiate and even be conceived to low-frequency band.But different with session in broadcasting, the situation of long-time continuous ground silence is few, in addition, owing to the advertisement that adds, audio etc., can be added in the sound of the high frequency that does not have in the reality " session " midway.

Through making up these characteristics, can differentiate " apparatus for receiving broadcasting crowd " and " session ".

According to above discriminating step, the sound that " air conditioner self ", " heavy housework is used device cluster ", " apparatus for receiving broadcasting crowd " are not perhaps differentiated for " session " is distinguished with " light housework is used device cluster ".

< structure of sound transducer >

Like this, separate by sound transducer 19 detected signals and extraction at each frequency band, and use it for judgement.Use Figure 23 that the structure of sound transducer 19 is described.Figure 23 is that source of sound is judged block diagram.

Indoor voice signal by sound transducer 19, be that microphone 408 captures, and be transformed to the signal of telecommunication.

Detected voice signal is small signal; Therefore need to amplify, but as air conditioner 1, needing big power and then having in the product with the circuit of high-frequency drive such as converter circuit, switching power circuit, power supply noise, switching noise are also bigger; Therefore; Noise overlaps onto in the voice signal easily, if former state ground amplifies, then has and has carried out the problem of amplifying under the overlapping noisy state.

Therefore; In the present embodiment; The installation site of microphone 408 is set on the substrate identical with amplifier; And near the high frequency high the removing of the frequency ratio source power supply high-pass filter (HPF400) that power supply noise uses (for example make more than the 100kHz of 2 doubling times of frequency 50kHz of source power supply through) being set the microphone 408 and when judging source of sound, shielding unwanted high frequency band is removed with low pass filter (LPF) 401 (for example shielding the frequency more than the 15kHz), suppresses noise.

In addition, LPF401 is made up of operational amplifier, as to the amplifier that amplified by microphone 408 detected voice signals and bring into play function.

The voice signal that has passed through HPF400 and LPF401 is imported into a plurality of filter circuits that are made up of differential circuit or integrating circuit based on operational amplifier.In addition, through using operational amplifier, can amplify when voice signal is carried out filtering, therefore can reduce number of components, amplify by stages, therefore can improve noiseproof feature, dispersion deflection voltage with operational amplifier.

In addition; In the present embodiment; Through using differential circuit or integrating circuit to come double as filter circuit and amplifier, thereby constitute at an easy rate, filter circuit and amplifier are set respectively but also can constitute based on operational amplifier; Interwoven crystal pipe and active component reduce amplifier, or pair amplifier uses the General Audio amplifier.In addition; For filter circuit; Also can be digital filter, based on the RC integrator of resistance and capacitor, the RCL passive filter that has made up inductance, capacitor and resistance and general digital-filter IC and then be installed in the A/D converter of APU and carry out Fourier transform etc.; Constitute 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, constitute voice signal is divided into 2 frequency bands.

One is to be made up of differential circuit 402 and integrating circuit 403, makes the bandpass filter (BPF) 404 that passes through near the low-frequency band of the frequency band of people's sound (for example make 1kHz～4kHz through).

Another is to be made up of differential circuit 405, the high-pass filter (HPF) 406 that the high frequency band that the such sound the people of mechanical sounds such as dust catcher can't be sent passes through (for example make more than the 5kHz through).

In addition, the output in these each filter circuits (BPF404, HPF406) is transformed to data signal in the comparator 407 that the back level is possessed.Like this; Constitute through microphone 408, filter circuit (HPF400, LPF401, BPF404, HPF406), amplifier (operational amplifier) and even comparator 407 are installed on the same substrate; To output to control assembly 10 by the data signal of two systems after comparator 407 conversion, suppress noise.

In addition, when amplifying through operational amplifier, if on the power line of operational amplifier, produce noise, then magnification change occurs as noise in voice signal.Therefore, also can on same substrate, be provided for suppressing the electrolytic capacitor (not shown) of power supply noise, make the power supply of supplying with the operational amplifier of giving filter circuit stable.

In addition; Through will by the threshold value that comparator 407 is transformed to data signal set only the operating sound through air conditioner 1 can't surmount; Can prevent because the operating sound of air conditioner self and malfunction, only constitute and when the voice signal of having imported from external sound source, to be input to control assembly 10.

In addition, in the present embodiment, as stated; Constitute voice signal is divided into 2 frequency bands; But also can with the number of the object of the object that detects, detection, substrate installing space, cost in combination, the change of frequency band, a plurality of filter circuit are set, unqualified to this structure.

In addition, in the present embodiment, also can constitute with detected voice signal in combination, light display lamp (with reference to Fig. 1).Thus, can make the user discern the situation that microphone 408 detects voice signal through vision.In addition, such advantage below also having, promptly when fault had taken place peripheral circuits such as contingency microphone 408, filter circuit, repair operation person can easily confirm fault.In addition; Because the fault of above-mentioned microphone 408, amplifying circuit etc.; Be taken into voice signal in the control assembly 10 (activity decision means 41) very little, or few situation under, the buzzer (not shown) that air conditioner 1 is possessed is blowed, according to the result who detects this buzzer sound; Can detect the unusual of 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 is carried out is described.

In step S101, activity decision means 41 is carried out sampled voice.

Specifically, through sound transducer 19 indoor sound is separated into the sound (sound (for example 5kHz) of 1kHz～4kHz), high frequency band and extracting out for example of low-frequency band.

In addition, for each frequency band, the sampling period is according to the rules carried out the sampling of stipulated time, calculates the ratio that detects number of times (BP) of the sound in the low-frequency band, the ratio that detects number of times (HP) of the sound in the high frequency band, as 1 time sampled result.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) size the level of sound is judged.

In addition, according to whole sampled result (BP ₁～BP _m, HP ₁～HP _m) whether be positioned at the continuity of a side of the determined defined threshold of each source of sound crowd being judged 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 in the judgement amplitude of the regulation that each source of sound crowd is confirmed, judge the systematicness of sound.

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

In addition, according to sampled result (BP ₁～BP _m, HP ₁～HP _m) be that number of times more than the threshold value of regulation that each source of sound crowd is confirmed is below the set upper limit frequency threshold value that each source of sound crowd is confirmed and is whether midway the interrupting in succession and sampled result (BP of number of times more than the threshold value 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 surpassed the judgement amplitude threshold of the regulation that each source of sound crowd is confirmed, judge whether sound has long interruption.

In addition, in following explanation, establish the sampled result (BP in the low-frequency band ₁～BP _m) mean value be BP _Mean, establish the sampled result (BP in the low-frequency band ₁～BP _m) maximum be BP _Max, establish the sampled result (BP in the low-frequency band ₁～BP _m) minimum of a value be BP _Min, establish the sampled result (HP in the high frequency band ₁～HP _m) mean value be HP _Mean, establish the sampled result (HP in the high frequency band ₁～HP _m) maximum be HP _Max, establish the sampled result (HP in the high frequency band ₁～HP _m) minimum of a value be HP _Min

In step S102, 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 all between sampling periods less than air conditioner judgment threshold (BP _a, HP _a) situation under, the kind of source of sound is judged as " air conditioner self ".

In step S102, satisfied under the situation of above-mentioned Rule of judgment, advanced to step S103, activity decision means 41 judges that source of sound is " air conditioner self ".On the other hand, under the situation that does not satisfy above-mentioned Rule of judgment, advance to step S104.

In step S104, activity decision means 41 judges whether source of sound is " heavy housework is used device cluster ".Specifically, at sampled result (BP ₁～BP _m, HP ₁～HP _m) size in all between sampling periods, be that housework is with device cluster judgment threshold (BP _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 in housework with device cluster _c, HWc) in, 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 in housework with device cluster _c, HW _c) with under the interior situation, the kind of source of sound is judged as " housework is used device cluster ".

In step S104, satisfy under the situation of above-mentioned Rule of judgment, advance to step S105, activity decision means 41 is judged as source of sound " heavy housework is used device cluster ".On the other hand, under the situation that does not satisfy above-mentioned Rule of judgment, advance to step S106.

In step S106, activity decision means 41 judges whether source of sound is " apparatus for receiving broadcasting crowd ".Specifically, at sampled result (BP ₁～BP _m, HP ₁～HP _m) be apparatus for receiving broadcasting judgment threshold (BP _t, HP _t) above number of times is apparatus for receiving broadcasting crowd's lower limit frequency threshold value (BL _t, HL _t) above 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) under the discontinued in succession situation of above number of times, the kind of source of sound is judged as " apparatus for receiving broadcasting crowd " on the way.

In step S106, do not satisfy under the situation of above-mentioned Rule of judgment, advance to step S107, activity decision means 41 is judged as source of sound " apparatus for receiving broadcasting crowd ".On the other hand, under the situation that does not satisfy above-mentioned Rule of judgment, advance to step S108.

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) above number of times is the lower limit frequency threshold value (BL of session _s, HL _s) above and be upper limit frequency threshold value (BH _s, HH _s) below, and then be session judgment threshold (BP _s, HP _s) under the discontinued halfway in succession situation of above number of times, the kind of source of sound is judged as " session ".

In step S108, satisfy under the situation of above-mentioned Rule of judgment, advance to step S109, activity decision means 41 is judged as source of sound " session ".

On the other hand, under the situation that does not satisfy above-mentioned Rule of judgment, advance to step S110, activity decision means 41 is judged as source of sound " light housework is used device cluster ".In addition, if loud, the one's voice in speech of session ceaselessly continue, then be not judged as session; But under these circumstances; The activity that carries out the people of session also increases, and becomes and uses cooking apparatus, beauty appliance, affairs with the activity of light housework such as equipment with the situation same degree of device cluster, therefore; In the control of air conditioner 1, regard as and used light housework to use device cluster.

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

Indoor; Even when indoor occupant is quiet; The various sound such as sound that the water pump of clock and watch, aquarium is also arranged, will be the time through sound transducer 19 control air conditioners 1, must consider the sound that made up when indoor occupant is quiet and air conditioner self sound and must the influence of sound.Therefore, in the air conditioner 1 of present embodiment, when entry into service, the sound when judging that according to flow process shown in Figure 24 indoor occupant is quiet.

When turning round at first at the machine of installing an air-conditioner 1; If this running is to turn round first; Then under the state of solemn silence, turn round or stop; Measure in (for example under the state in solemn silence entry into service 1 minute) during the reference atmosphere sound measurement of measuring basis ambient sound through sound transducer 19, the initial value substitution that will in each time period, store in the storage device (not shown) of air conditioner 1 is an a reference value.

With at this moment sampled result on average be named as initial value, compare with a reference value that air conditioner self is confirmed (roughly the mean value of the sampled result when under same environment, turning round is consistent).

In result relatively is under the situation of a reference value less than initial value; In the judged result of source of sound (with reference to step S103) under the situation of air conditioner self; Even indoor is quiet; The sound indoor ambient sound in addition that also is thought of as air conditioner self has produced influence to the result, and the judgment threshold of each source of sound is revised.

Judged result at source of sound is under the source of sound crowd's beyond the air conditioner self the situation, is judged as the significant sound that is not that air conditioner self is such with ambient sound, does not carry out the correction of the judgment threshold of each source of sound.Result in that initial value and a reference value are compared is that a reference value is under the situation more than the initial value, can fully discern and judge each source of sound according to current judgment threshold, does not therefore carry out the correction of the judgment threshold of each source of sound.

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

The action of burnt electric type infrared ray sensor 17 then, is described.

Burnt electric type infrared ray sensor 17 is caught the variation from indoor ultrared amount with Fresnel Lenses 17a.When active motion was arranged, its reacting dose was big indoor, and when undisturbedly moving, reacting dose is little.Utilize these, the signal from the electric type infrared ray sensor 17 of Jiao is amplified, carry out digitlization through comparator (not shown), and be delivered to control assembly 10 (activity decision means 41) through the bandpass filter (not shown) that moves of extracting the people out.

Activity decision means 41 is under the sampling period (for example 10ms) of regulation; During sampling interval (for example 60 seconds); To sampling from the data signal of this Jiao's electricity type infrared ray sensor 17, the reaction in the data of calculating sampling detects the ratio of data, obtains reaction and detects ratio Px.

Detect under the situation of ratio Px less than the whether little quiet judgment threshold Pb of the amount that is used to differentiate indoor motion in this reaction, the detection zone branch of reaction is divided into " reaction: quiet ".

Then, whether big detect ratio Px in reaction is under the situation about differentiating more than the amount of indoor motion the motion determination threshold value Pv, and the detection zone branch of reaction is divided into " reaction: strong ".

Detecting ratio Px in reaction is under the situation more than the quiet judgment threshold Pb, less than motion determination threshold value Pv, the detection zone branch that reacts is divided into " reaction: in ".

Then, use Figure 26, explain that the combination through electric type infrared ray sensor 17 of Jiao and sound transducer 19 comes activity is segmented the method for judging.Figure 26 is the figure that explanation combined moving amount is judged.

Activity decision means 41 combination is distinguished (quiet, strong, in), is judged the result of (air conditioner self, heavy housework with device cluster, apparatus for receiving broadcasting crowd, session, gently housework is used device cluster) based on the source of sound of the detection signal of sound transducer 19 based on the reaction detection of the detection signal of the electric type infrared ray sensor 17 of Jiao; That kind shown in figure 26 is segmented the activity of indoor occupant.

In addition, in Figure 26, air conditioner self, apparatus for receiving broadcasting crowd's (TV) situation is changed little source of sound set as thalposis, will weigh housework and change big source of sound with the situation of device cluster (other) as thalposis with device cluster (dust catcher), session, light housework and gather.

Like this; Even the reaction detection based on the detection signal of the electric type infrared ray sensor 17 of Jiao is distinguished identical; At source of sound is that the thalposis that is accompanied by the activity of indoor occupant changes under the situation of big source of sound set; The situation that changes little source of sound set with the thalposis that source of sound is with the activity of indoor occupant has nothing to do is compared, and judges activity bigger.

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

In the example of Figure 26; If the reaction of burnt electric type infrared ray sensor 17 detects and distinguishes is " reaction: strong ", the activity that the thalposis that the kind of source of sound uses device cluster, session and light housework to use device cluster to form by heavy housework changes the situation of big source of sound set is maximum.In addition, for the activity of minimum, the reaction of establishing burnt electric type infrared ray sensor 17 detects and distinguishes is " reaction: quiet ", and source of sound is to be changed by the thalposis that air conditioner self becomes with apparatus for receiving broadcasting group that activity is a minimum under the situation that little source of sound gathers.

In addition,, detect in the reaction of the electric type infrared ray sensor 17 of Jiao and to distinguish under the identical situation, confirm that the activity that activity makes thalposis change little source of sound set is that thalposis changes more than the activity of big source of sound set for activity.In addition, under the identical situation of the source of sound of sound transducer 19 set, confirming that activity makes becomes the relation of " reaction: quiet "＜" reaction: in "＜" reaction: strong ".

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

In addition, when the warming operation of air conditioner 1, under the big situation of the activity of indoor occupant; Be that indoor occupant moves and the active state of metabolism actively, the body internal heat generation is big, and the warm sensation of indoor occupant also is changed to a hot side; Therefore; Even reduce room temperature a little, comfortableness also in the scope of allowing, can be carried out energy-saving operation with the amount that reduces room temperature a little accordingly.

The activity that activity decision means 41 is judged is sent to temperature drift value set parts 42, and temperature drift value set parts 42 is according to the activity of being judged by activity decision means 41, design temperature deviant.In addition, by target temperature set parts 44 according to temperature drift value target setting temperature.In addition, by air-conditioning ability control assembly 45 control compressors 51, indoor blower 52, outdoor draft fan 53, make intake air temperature (by the temperature of temperature sensor 11 detections) near target temperature.

Like this; In the present embodiment, except the electric type infrared ray sensor 17 of Jiao, also utilize sound transducer 19 to judge activity in more detail; According to the activity target setting temperature of judging; Therefore, the state (active state) that combines with indoor occupant can be provided, energy-conservation air conditioner 1 when considering comfortableness.
