Next, 29~Figure 31 of reference picture, to 2 voice recognition sensor NS1, NS2, people as speech recognition facility Body detection sensor HS, illuminance transducer LS are illustrated.
As shown in Figure 29~Figure 30,1 voice recognition sensor NSl, human body detection sensor HS, illuminance transducer LS match somebody with somebody It is placed in the upper surface of the casing 11 of refrigerator 1.Another voice recognition sensor NS2 is configured to and 1 in the bottom of for example right door 22 Individual voice recognition sensor NSl is separated by a distance.As these voice recognition sensors NS1, NS2, such as condenser type can be used Microphone, it is not particularly limited.
As shown in figures 30 and 31, the voice recognition sensor NSl of upside is configured at the upper surface of the casing 11 of refrigerator 1, The voice recognition sensor NS2 of downside is configured in the bottom of for example right door 22, it is however not limited to this, can also only configuration 2 The voice recognition sensor of any one party in individual voice recognition sensor NS1, NS2.
As the human body detection sensor HS shown in Figure 31, such as infrared ray sensor can be used.It is upper shown in Figure 31 Voice recognition sensor NSl, human body detection sensor HS, the illuminance transducer LS of side be accommodated in respectively receiver CS1, CS2, CS3.Thus, voice recognition sensor NSl, human body detection sensor HS, illuminance transducer LS can overlap in casing 11 Upper surface, can also side by side configure, can obtain protecting without falling ash.Receiver Cl, C2, C3 are in the upper surface of casing 11 The position being configured between such as opening door operation portion 51,52, still, the allocation position not limited to this of each sensor.
In addition, these sensors can be accommodated in the housing of enabling drive division 54,55, can also be accommodated in for covering The fulcrum that is, the housing of hinge being opened and closed on the door.
Figure 32 is the block diagram of the enabling control of refrigerator.Figure 33 flow chart represents to automatically open up left-hand door 21 and the right side of refrigerating chamber The situation of door 22.
As shown in figure 32,2 voice recognition sensor NS1, NS2, human body detection sensor HS, illuminance transducer LS and control Portion 56 processed electrically connects.Thus, voice signal when 2 voice recognition sensors NS1, NS2 receive sound can be sent to control Portion 56 processed.Human body detection sensor HS detection signal can be sent to control unit 56.Illuminance transducer LS illumination intensity signal can To be sent to control unit 56.
By setting 2 voice recognition sensors NS1, NS2 like this, flow chart as shown in figure 33 is such, user Spoken with voice, be not thus left-hand door 21 and right door 22 by user's manual unlocking refrigerating chamber, i.e., except user hold handle Hand (handgrip) is opened beyond door, and different detection (operation) methods for detecting sound, voice etc. can be utilized to be automatically turned on, behind Illustrate.
In addition, as shown in figure 32, control unit 56 is connected with storage part 300 and relevance input registration unit 305.Associating Property input registration unit 305 in, user can input " title of food as storage item etc. ", such as " receipts of left-hand door 21 Receive the title of shelf ", " title of the storage shelf of right door 22 ", " title of the housing portion in the refrigerator of refrigerator 1 " etc. enter Row registration." title of food as storage item etc. " is such as " milk ", " egg ", " butter ", " fruit juice ", " mustard ", " beans It is rotten " etc..Refrigerating chamber 12 as shown in figure 29, vegetable compartment 13, switching chamber exemplified by " title of the housing portion in the refrigerator of refrigerator 1 " 14th, refrigerating chamber 15, ice-making compartment 16 etc..
Control unit 56 shown in Figure 32 stores above-mentioned " title of food as storage item etc. " in storage part 300 and is put into The related information of " title of which housing portion in the refrigerator of refrigerator 1 ".As an example, in storage part 300, use Person can set (storage) such as " milk ", " egg ", " butter " on the storage shelf of the side of left-hand door 21, in step s 12, (storage) such as " fruit juice ", " mustard ", " bean curd " is set on the storage shelf of the right side of door 22.
Here, with reference to the flow chart for automatically opening up Figure 33 in the case of the left-hand door 21 and right door 22 of refrigerating chamber, specifically Illustrate that user is automatically turned on the situation of left-hand door 21 and right door 22 by voice.
In fig. 33, in step s 11, the advance operative association of user inputs such as keyboard of registration unit 305, touched Template etc., such as " milk ", " egg ", " butter " are inputted in association with the storage shelf of the side of left-hand door 21 and is registered, to the right side The input of storage shelf such as " fruit juice ", " mustard ", " bean curd " of 22 sides of door are registered.Thus, the control unit shown in Figure 32 56 make the storage shelf of storage part 300 and the side of left-hand door 21 shown in Figure 32 set (storage) such as " milk ", " chicken in association Egg ", " butter ", in step s 12, (storage) such as " fruit juice ", " mustard ", " beans are set for the storage shelf of the right side of door 22 It is rotten ".
In Figure 33 step S13, by detecting to use such as human body detection sensor HS or illuminance transducer LS Person is close to refrigerator, thus sends detection signal from human body detection sensor HS to control unit 56, or from illuminance transducer LS sends illumination intensity signal to control unit 56.Therefore, in control unit 56, control unit 56 is caused by detection signal or illumination intensity signal The triggering that starts of speech identifying function, i.e., the opportunity for playing speech identifying function is produced in control unit 56, thus, control The speech identifying function in portion 56 is started working.
So, the triggering that the speech identifying function starts is:Detect to make close to refrigerator in human body detection sensor HS In the case of user, when detection signal is sent from human body detection sensor HS to control unit 56, or in illuminance transducer LS inspections In the case of measuring the kitchen illumination that user opens placement refrigerator, illumination letter is sent from illuminance transducer LS to control unit 56 Number when.
Next, in Figure 33 step S14, user is said in " milk ", " egg ", " butter " at least with voice At 1, voice recognition sensor NS1, NS2 shown in Figure 32 receive the voice and send voice signal to control unit 56, therefore Control unit 56 identifies voice.Thus, in step S15, control unit 56 is for being at least accommodated with " milk ", " egg ", " butter " In at least one Figure 32 shown in the enabling drive division 54 of left-hand door 21 export enabling driving instruction, make enabling drive division 54 dynamic Make.Therefore, in step s 16, the storage shelf of left-hand door 21 can be automatically turned under the action of enabling drive division 54.
Equally, in step S14, when user says at least one in " fruit juice ", " mustard ", " bean curd " with voice, figure Voice recognition sensor NS1, NS2 shown in 32 receive the voice, send voice signal to control unit 56, therefore control unit 56 is known Other voice.Thus, in step S17, control unit 56 is to the right door of at least one being accommodated with " fruit juice ", " mustard ", " bean curd " 22 enabling drive division 55 exports enabling driving instruction, acts enabling drive division 55.Therefore, in step S18, right door 22 Storage shelf can be automatically turned under the action of enabling drive division 55.
In storage part 300, such as the advance storage for registering the side of left-hand door 21 for being put into " milk " in association is put Frame, even not knowing the people at the position being put into the refrigerator of " milk ", if saying " milk ", a left side can be automatically turned on Door 21.Thus, it is not known that the people at the position being put into the refrigerator of " milk " will not mistakenly open the right door for not being put into " milk " 22.Therefore, the either on or off number of door is reduced, and improves energy-saving effect.
In addition, in the case of being configured with the water tank of ice making in refrigerator, for example said " water storage ", put by user Put the door of water tank side, such as left-hand door 21 will be opened, user can receive water tank in the state of water tank is held The regulation reception position for the water tank being contained in refrigerator.Thus, even in user's both hands hold water tank and what both hands took In the case of, it can also be automatically turned on being opened for example left to store water tank without using the handle 61 shown in Figure 29 Door 21.
In addition, for the plug-type door 23,24,25,26 shown in Figure 29, can also be driven by setting to open the door respectively Dynamic portion, automatic door opening is carried out in the same manner as left-hand door 21 and right door 22 using voice.
So, handle is caught with user to manually turn on left-hand door 21, right door 22, plug-type door 23,24,25,26 Manually operated difference, door can be automatically turned on, therefore in the case of holding food such as user's both hands etc., very It is convenient.
In addition, in the case of the voice that the door that identification is sent as an envoy to different at the same time opens, can be by making these different doors Opening opportunity open etc. with staggering, prevent door produces with user from conflicting.
In addition, in the step S13 shown in Figure 33, the triggering started for speech recognition is provided as to control unit 56 Example, speech recognition is come from obtained from being the language (word) sent as voice recognition sensor NSl, NS2 identification user Sensor NSl, NS2 voice signal.The predetermined language (word) sent as user, such as " sesame can be used Numb quick operating valve " etc..I.e., as the preference for providing the control unit 56 triggering started for speech recognition, it is desirable to be for example " open sesame ", and then the word for being not in usual session as " sesame quick operating valve ".
I.e., in the case where the example for providing control unit 56 triggering started for speech recognition is the sound of people, it is Prevent that may result in control unit 56 using the word occurred in common session content proceeds by speech recognition action The problem of, it is preferably used in the word in common session be not in.Thus, it is possible to prevent control unit 56 from mistakenly starting language Sound identification maneuver.Control unit 56 is provided the triggering started for speech recognition voice can be set to refrigerator caused by it is miscellaneous The dust catcher or room used in sound, the sound such as compressor, warning tones when being opened by door, the opening and closing sound of door, room Between middle broadcasting music etc. the different sound of sound.In addition, when the sound that will be identified is set as the sound of non-voice, such as Fruit is set to identification repeatedly (such as 2 times) sound for clapping hands, then because from refrigerator caused by sound it is different, therefore be not in mistake Switch.
Next, reference picture 34 illustrates the voice recognition sensor NS2 of the bottom for being configured at right door 22 shown in Figure 30 Configuration example.Figure 34 is the schematic diagram of the cross section of for example right door 22.
As shown in figure 34, voice recognition sensor NS2 is such as capacitance microphone, is configured at the bottom of right door 22.The language Sound identification sensor NS2 is configured in storage member 105.The storage member 105 is fixed in the inner surface of glass plate 121 respectively 121M and offside door cover 135 inner surface 135M.The storage member 105 is the portion for being configured to store the incorporating section of substrate 110 Part.Hole portion 154 is arranged at the bottom of the offside door cover 135 of for example right door 22.Voice caused by user etc. by hole portion 154 and Reach voice recognition sensor NS2.The hole portion 154 can be made up of single hole or be made up of multiple holes.By This, voice recognition sensor NS2 can be configured to be built in the bottom of right door 22, and can be by hole portion 154 and reliable Voice outside ground pickup etc..In addition, voice recognition sensor NS2 can be equipped on substrate 110, it is possible to have covering hole The lid in portion 154, and to form aperture covering.
As shown in figure 32, control unit 56 is connected to illuminating part 330, sound generating unit 340, voice generating unit 350.Illuminating part 330th, sound generating unit 340 and voice generating unit 350 are in the sound (language detected using voice recognition sensor NS1, NS2 Sound) come in the case of opening door, inform that what the goalkeeper was opened informs mechanism to user to alert.
Illuminating part 330 is such as LED illuminating parts, and sound generating unit 340 is such as buzzer.Voice generating unit 350 is example Such as loudspeaker.As described above, at least one party of voice recognition sensor NS1, NS2 shown in Figure 32 detect the voice of user, Control unit 56 sends the instruction for opening such as left-hand door 21 or right door 22, and control unit 56 can make the illuminating part 330 shown in Figure 32 It is luminous with such as " redness of the skin or complexion ", sound generating unit 340 is produced alarm tone or make voice generating unit 350 with voice to making User informs that " goalkeeper is opened " etc. alerts content.Thereby, it is possible to user is informed with least one of light, sound, voice Goalkeeper is opened, therefore, it is possible to prevent user from being bumped against accidentally by door.
In addition, as shown in figure 32, human body detection sensor HS is connected to control unit 56.Human body detection sensor HS is detected During to user close to refrigerator, detection signal is sent to control unit 56 and notifies to detect people.So, control unit 56 is detecting During to user close to refrigerator, control unit 56 as shown in figure 32 can by voice generating unit 350 by voice guide come to User's inquiry " opens door" such inquiry content.In this case, should if user answers such as " YES " " YES " is identified by voice recognition sensor NS1, NS2, and voice signal is notified to control unit 56.Thus, control unit 56 is logical Cross to the enabling drive division 55 of for example right door 22 and export enabling driving instruction, right door 22 can be opened.Equally, control unit 56 passes through Enabling driving instruction is exported to the enabling drive division 54 of such as left-hand door 21, left-hand door 21 can be opened.
In addition, the left-hand door 21 and right door 22 can make respective opening speed different.Left-hand door 21 and right door 22 are in drive of opening the door Under the driving in dynamic portion 54,55, generally opening speed is set to slowly slack-off, door is not drastically opened.
As shown in figure 35, height measurement sensor 410 is connected with control unit 56.The height measurement sensor 410 can be with Using optical sensor as such as optical coupling, the substantially height of user is measured.As long as such as, height measurement sensor 410 Can discriminating measurement go out user height values reach the left-hand door 21 of upper layer side and the value of right door 22 or not up to value i.e. Can.Thus, control unit 56 can make the left-hand door of upper layer side based on the height values of the user of the measure of height measurement sensor 410 21 is different from the opening speed of right door 22.
Such as, the height values of user measured in height measurement sensor 410 be to reach the and of left-hand door 21 of upper layer side In the case of the value of right door 22, control unit 56 makes the action of enabling drive division 54,55 further slack-off, enabling drive division 54,55 Left-hand door 21 and the right door 22 of upper layer side is set to be opened with the speed further to slow down than respective normally open speed.
Thus, it is possible to left-hand door 21 and right door 22 is avoided to bump against head or the body of user.Sensed in addition, being measured in height In the case that the height values for the user that device 410 is measured are the left-hand door 21 of not up to upper layer side and the value of right door 22, open the door and drive Dynamic portion 54,55 makes the left-hand door 21 of upper layer side and right door 22 each be opened with common opening speed.
User, which is informed, using voice generating unit 350 in the control unit 56 shown in Figure 32 or Figure 35 " will for example open In the case of the such warning content of right door ", when the user wants to confirm the warning content again, it can enter as follows OK.When user, which says " again " or " repetition " such repetition, urges content, voice recognition sensor NS1, NS2 will " again " or " repetition " such voice signal for repeating urgency content is sent to control unit 56.Control unit 56 by from Voice recognition sensor NS1, NS2 voice signal, at least user, which is informed, again using voice generating unit 350 " will beat Open right door " such warning content.Thus, also can simply again even if user misses the warning content that refrigerator side is sent Secondary confirmation.
In addition, opening the right door 22 of the refrigerating chamber on upper strata in user during to being observed in refrigerator, control unit 56 is not Receive the operation for example automatically opened up as other left-hand door 21.Thus, in the right door 22 of user's opening to entering in refrigerator Row observation, and user is muttered to oneself when saying such as " milk must also take out ", can prevent from being placed with the left-hand door 21 of " milk " side Mistakenly automatically open up, can reliably prevent left-hand door 21 from bumping against such as face of user.
Equally, the right door 22 of the refrigerating chamber on upper strata being opened in user during to being observed in refrigerator, muttering to oneself and saying " vegetable Dish must also take out " when, can prevent from being placed with the door of the vegetable compartment of " vegetables " mistakenly automatic spring and bump against under user Belly or knee etc..
In addition, in addition to making receiving invalid as described above, can also be set to when some door is opened makes it The breakaway speed of his door is slower than common speed.
In addition, when refrigerator sends noise (compressor sound, buzzer sound), speech recognition becomes well to be known In the case of other, the instruction voice to user such as " please say it again " can also be sent from loudspeaker.
As shown in figure 35, proximity transducer 400 is connected with control unit 56.The proximity transducer 400 is configured at for example left Door 21 and right door 22, when user makes hand close to left-hand door 21 or right door 22, opening door operation portion 51 as soft-touch control, 52nd, control operation portion 50 uses and lighted such as LED.Thus, even if the position for placing refrigerator is dark place, user Opening door operation portion 51,52, the position in control operation portion 50 can visually be confirmed.
Furthermore, it is possible to have the function of the proximity transducer and the function of opening door operation portion 51,52 concurrently.In this case, such as Shown in Figure 35, without being positioned proximate to sensor 400 in addition.

Figure 41 shows example below:The opening door operation portion 51 of left-hand door 21 shown in Figure 37~Figure 39 and the enabling of right door 22 Operating portion 52 works as the human testing mechanism of the human body of the user for detecting refrigerator 1.
After the opening door operation portion 51 and opening door operation portion 52 detect the human body of user, human testing is sent to control unit 56 Signal.Thus, control unit 56 makes the input of the operation signal from opening door operation portion 51 effective, carries out opening for corresponding left-hand door 21 Gate control, and make the input of the operation signal from opening door operation portion 52 effective, carry out the enabling control of corresponding right door 22.
In the case of by taking the opening door operation portion 52 for example as human testing mechanism as an example, control unit 56 is in opening door operation After portion 52 detects the human body of user, the display of opening door operation portion 52 is opened.Control unit 56 can be grasped according to the enabling of right door 22 The mode of work switches by the bright light of opening door operation portion 52 display that carries out.
Opening door operation portion 52 as human testing mechanism is static switching as already described, and static switching enters During the detection of the human body of row user, control unit 56 can improve the sensitivity of static switching come examinations by switching.Make It is for the opening door operation portion 52 of human testing mechanism:The proximity transducer detected during human body proximity, control unit 56 are cut The sensitivity of the opening door operation portion 52 as the proximity transducer is changed, opening door operation portion 52 is worked as feeler, And make the opening door operation of right door 22 effective, meanwhile, detect user by the use of finger contact as feeler enabling grasp During the portion 52 of work, the actual opening door operation for carrying out right door 22 of control unit 56.
As described above, the sensitivity by switching opening door operation portion 52, makes opening door operation portion 52 from proximity transducer conduct Feeler is worked, and more specific description is carried out to this referring to Figure 41 example.
In Figure 41 (a), control unit 56 is in order that the opening door operation portion 52 as static switching rises as " proximity transducer " Effect, by the way that the sensitivity of opening door operation portion 52 is set as into " height ", the function as " proximity transducer " " has control unit 56 Effect ".Therefore, control unit 56 makes opening (opening door operation) engineering noise of the right door 22 as original function of opening door operation portion 52. Also, control unit 56 cause opening door operation portion 52 bright light show it is shown in dotted line as be closed mode.
Next, in Figure 41 (b), when user makes finger HT close to the opening door operation portion 52 as " proximity transducer " When, opening door operation portion 52 is worked as " proximity transducer " to detect the close of hand.Opening door operation portion 52 detects in one's hands connect When near, control unit 56 sets the spirit as " proximity transducer " of opening door operation portion 52 in a manner of switching to " low " from " height " Sensitivity.Therefore, control unit 56 makes opening door operation portion 52 play a part of " feeler " as original function, therefore, leads to The opening operation (opening door operation) " effective " for the right door 22 received and distributed abutment opening door operation portion 52 and carried out.Also, control unit 56 So that as the bright light of opening door operation portion 52 is shown as shown by the solid line, become opening from closed mode, for example, by LED Make the bright light of opening door operation portion 52.
Then, in Figure 41 (c), grasped when user makes finger HT directly contact (touch) as the enabling of " feeler " During the portion 52 of work, control unit 56 maintain opening door operation portion 52 as the sensitivity of " feeler " that is, the state of " low ", directly Connect and worked as " feeler ".Then, control unit 56 causes the right door 22 as original function of opening door operation portion 52 Opening (opening door operation) maintain " effective ".Also, control unit 56 causes the bright light of opening door operation portion 52 to show as shown in realizing As, it is opening, makes the bright light of opening door operation portion 52 for example, by LED.
Afterwards, in Figure 41 (d), when control unit 56 identifies the finger HT of user departing from direct contact (touch) conduct " during the state for the opening door operation portion 52 that feeler (touch sensor) works, control unit 56 makes to come from opening door operation portion The input of 52 operation signal is effective, acts enabling drive division 55, thus, carries out the enabling control of corresponding right door 22.By This, right door 22 can automatically open up.
Thus, in the state of user goes in the directly action way of contact (touch) opening door operation portion 52, such as user thinks Will be close in the state of refrigerator 1, in order to prevent the error detection of enabling instruction, control unit 56 can interpolate that directly contact (touch) Effectively, it is invalid.
In addition, the bright light of opening door operation portion 52 show as shown by the solid line as be opening, can be for example, by LED To make the bright light of opening door operation portion 52, therefore, for a user, it is possible to increase shown by the LED bright lights of such as opening door operation portion 52 The identity of opening door operation portion 52 caused by showing.

The overhead illumination 750 of refrigerator 1 shown in Figure 44 has such as LED (light emitting diode) lamp, is configured to be embedded in top The recess 733 of the heat-barrier materials such as the polyurethane in portion 730.Therefore, overhead illumination 750 does not protrude from the 755 downward side of inwall at top Out.Vacuum heat insulation material 740 is kept apart with the overhead illumination 750 by inwall 755.
Next, 45~Figure 47 of reference picture, illustrate the variation of the 29th embodiment, the 29th shown in Figure 45~Figure 47 is real Apply the refrigerator of the variation of mode position and Figure 44 shown in the 29th embodiment refrigerator the substantially identical situation in position Under, carry out its explanation using same-sign.
Figure 45~Figure 47 is section along the longitudinal direction on the top for the refrigerator for representing other variations respectively as Figure 44 Face figure.
First, in the refrigerator 1 of the 1st variation shown in Figure 45, overhead illumination 750 is configured to and the inwall at top 755 Contact, the LED 750a of overhead illumination 750 are configured at the outside (on the inside of refrigerator) of the inwall 755 at top, are thus exposed to refrigeration It is indoor.Also, overhead illumination 750 is configured at the kink 757 of the inwall 755 at top.
In addition, the kink of the inwall 755 at top is set to divide 11C's relative to the top 11A of casing (main body) 11 recess Kink and be located at front side, on the fore-and-aft direction of the kink of kink and inwall 755 therefore, it is possible to outside the enclosure wall between Space is formed at gap, thus vacuum heat insulation material can be configured along the vertical direction therebetween.Therefore, can be by vacuum heat insulation material The kink of part is configured at the space in 740 way.Moreover, the vacuum heat insulation material configured along the vertical direction can also be point The split material cut open.Alternatively, it is also possible to make along the vacuum heat insulation material of above-below direction configuration than other positions along front and rear The vacuum heat insulation material of direction extension is thin.In such manner, it is possible to reduce the kink of cabinet exterior and the kink of inwall 755 front and rear The space in the gap on direction, therefore, it is possible to make the kink of inwall 755 Back allow, by increasing capacitance it is possible to increase the capacity in refrigerator.
In addition, the recess of the kink of outer wall divides the angle of the front side of 11C bottom and the top of the kink of inwall 755 The angle of side (recess divides 11C sides) apart from size, the thickness than other top 11A without kink is small, therefore, such as Fruit is polyurethane heat-barrier material, then thermal insulation is possible to be deteriorated, still, by using the structure for including above-mentioned vacuum heat insulation material Into thermal insulation can be greatly improved.
In the refrigerator 1 of the 2nd variation shown in Figure 46, vacuum heat insulation material 770 is divided into some, vacuum every Hot material 770 is divided into part 1 771 and part 2 772.Part 1 771 covers the lower lateral areas of enabling drive division 54 (55) Domain part, part 2 772 cover the underside area part of control base board 710.The LED 750a of overhead illumination 750 and vacuum every The part 1 771 of hot material 770 have interval, the part 2 772 of the vacuum heat insulation material 770 of the side of control base board 710 with it is interior Wall part 776 contacts.
In addition, the vacuum heat insulation material of part 1 771 and part 2 772 be configured to it is overlapping in the longitudinal direction.This is Form below:Divide 11C's relative to the top 11A of casing (main body) 11 recess by the kink for the inwall 755 for making top Kink and be located at front side, the kink of outside the enclosure wall is formed with the gap location on the fore-and-aft direction of the kink of inwall 755 Space, therefore can be overlapping.
In addition, the kink of outer wall recess divide 11C bottom front side angle and the kink of inwall 755 it is upper Thickness hour of the size than other top 11A without kink between the angle of square side (recess divides 11C sides), manufacture The polyurethane of Shi Zuowei foam heat insulating materials is difficult to flow through sometimes, therefore, can by not configuring vacuum heat insulation material therebetween Ensure the space of polyurethane flowing so that polyurethane is reliably filled, and can improve filling speed.
In the refrigerator 1 of the 3rd variation shown in Figure 47, the kink 780 of the inwall 755 at top is formed obliquely.Top Portion's illumination 750 corresponds to the shape of inclined kink 780 and is formed as such as right triangular shape, and overhead illumination 750 configures Into being embedded in the kink 780.Vacuum heat insulation material 740 is not divided, is one thing.So, the LED of overhead illumination 750 Lamp 750a is configured in kink 780, and overhead illumination 750 does not contact with vacuum heat insulation material 740 and has interval.
In the 29th embodiment, can also by user with the opening door operation portion 51 shown in finger sustained touch Fig. 1, 52 is more than certain time, door opener is worked.
Such as, long range detection sensor 100 shown in Figure 42 user (user) human body positioned at from refrigerator 1 farther out It is such as infrared ray sensor for detecting human body in the case of position, still, on that will be used to sense the remote detection The infrared ray of device penetrates into the hole (opening) that front panel printing coatings square in front of the door are rejected and formed, and can also be configured in the hole Upper stickup is with printing coatings with infrared ray permeation member of colour system etc..Furthermore, it is possible to by forming multiple apertures at the position The mode brushing paint of (opening) etc. makes the rejecting of coating less eye-catching.In addition, thus, it is possible to so that it is configured at glass backboard The long range detection sensor as infrared ray sensor in face is difficult to be observed from front.Furthermore, it is also possible to make the coating be Through the coating of infrared ray, or have:Pass through IR wavelength light by sputtering, etching etc. and make one of visible ray Divide the semipermeability mechanism for being difficult to pass through.In this case, as semipermeability mechanism, the color of wavelength length can be utilized to pass through Mechanism.For example, it is configured to the red wavelength (such as 620-750nm) for making the wavelength (450-495nm) of wavelength ratio blueness long Through when, then the wavelength (such as more than 760-830nm) as the infrared ray of the long wavelength more than this readily penetrates through.Moreover, In this case, the color of the indication mechanism near infrared ray sensor, pass through the luminous of the color grown also with wavelength Mechanism (green, yellow, the light emitting diode etc. of redness of the skin or complexion), the display of the light can also pass through semipermeability mechanism, make user It can identify, and be difficult to infrared ray sensor, the part inside door.
In addition, the long range detection sensor as infrared ray sensor can also be configured at substrate, with control operation portion 50 Or opening door operation portion 51,52 is inserted together.In such a case it is possible to by control operation portion 50 or opening door operation portion 51,52 Electrode part rejecting, or slit is set so that infrared ray can be sent from the lateral door side in the back side of the electrode.This Sample, long range detection sensor are readily detected the user operated.Moreover, long range detection sensor can also be arranged at control Between operating portion 50 processed and the opening door operation portion 51,52 for touching opening SW.

Opening door operation portion 551 and opening door operation portion 552 shown in Figure 48 have it is identically constructed, however, it is possible to be that left and right is right Claim shape, can also be left and right same shape.Figure 51 shows the shape example of the substrate 553 of opening door operation portion 551, still, opens Door operation portion 552 and opening door operation portion 551 are substantially the same shapes, and therefore, 51~Figure 53 of reference picture is with opening door operation portion 551 substrate 553 illustrates for representative.
First, reference picture 53, opening door operation portion 551 have:Substrate mounting body 500M, for storing substrate mounting body 500M Be referred to as be open box body plastics accommodation space part 585 and plastics cover 590.In plastics accommodation space The back side 585R of part 585, preferably it is pasted with such as aluminium foil as metallic object.In the inner surface of plastics cover 590, glue Post the metallic objects such as aluminium foil 591.Thus, electromagnetic wave caused by the main body side of refrigerator 1, substrate mounting body 500M sides will not be caused Influence.
Substrate mounting body 500M has:Plastics shield 599, substrate 553, operate sign board 597, be equipped with display use LED557 LED-baseplate 598.Substrate 553 is electrostatic soft-touch control substrate, and the front-surface side of shield 599 is fixed on by support. Operation sign board 597 is configured with the front-surface side of substrate 553.In the rear side of shield 599, it is fixed with display and uses LED-baseplate 598.Multiple LED577 are equipped with the LED-baseplate 598.Shield 599 is as 2 substrates 553 of support, LED bases The indicating mechanism of plate 598 and the space mechanism of LED light interval is set to work.
Substrate 553 and operation sign board 597 correspondence position, formed with left and right slit 574,575 (light transmission mechanism).It is narrow The position of seam 574,575 is located adjacent between sensor 560 and middle region part 589.Substrate mounting body 500M, which is passed through, to be received Receive spatial component 585 oblong openings part 586 and be accommodated in accommodation space part 585.Accommodation space part 585 is opened The covered part 590 of oral area point 586 covers.
As shown in Figure 51 (a) and Figure 52, the substrate 553 of opening door operation portion 551 is the rectangle or square of lengthwise, base Plate 553 has the back side 553B shown in surface 553A and Figure 51 (b) shown in Figure 51 (a).Electronic unit is provided with substrate 553 Carry part 571, the configuration section 572 of proximity transducer 560 and guard electrode 570.In the electricity shown in Figure 51 (a) and Figure 52 The carrying part 571 of subassembly, take in a manner of the recess to be rearwardly highlightedly accommodated in as the shield 599 of space mechanism It is loaded with required electronic unit, connector component etc..In addition, by not protruded on the surface of substrate 553 and general planar State forms metal electrical connection section 571b, can make the rear-face contact of substrate 553 and glass door.
Moreover, covered by using the operation sign board 597 for being used to cover substrate 553 as lid mechanism, can Prevent from producing noise when generation malfunction and electrostatic lodge in glass door when user from contacting electrical connection section 571b.In addition, should Operation sign board 597 can be the plate of coloring or the plate of evaporation.
It is configured with the configuration section 572 of the surface 553A sides shown in Figure 51 (a):As the 1st electrode close to sensing Device 560, the guard electrode 570 as the 3rd electrode, the middle region part 589 as the 2nd electrode.Middle region part 589 is set It is placed between proximity transducer 560 and guard electrode 570.Proximity transducer 560, guard electrode 570 and middle region part 589 It is metal electrode, still, is electrically insulated from each other.Middle region part 589 as the 2nd electrode aids in proximity transducer 560, tool There is the function as proximity transducer.Guard electrode 570 changes the detection effective range of proximity transducer 560.
In addition, as shown in Figure 51 (b), the back side 553B corresponding to the configuration section 572 in substrate 553, conduct is configured with The netted grounding pattern 573 of 4th electrode.Thus, the grounding pattern 573 causes the noise from refrigerator main body not passed to close Electromagnetic field caused by electromagnetic field caused by sensor 560 and guard electrode 570 has an impact.
As shown in Figure 51 (a) and Figure 52, in the middle position of proximity transducer 560 formed with through hole 560C, still, at this On through hole 560C, as shown in Figure 51 (b), wire pattern 560H is connected with.User presses with finger proximity transducer 560 (contact) Behavior, typically carried out with the center of proximity transducer 560 for target, therefore through hole 560C is formed at proximity transducer 560 center position.
The reasons why through hole 560C is formed to the position substantially hit exactly of proximity transducer 560 like this is as follows.I.e., connecing In nearly sensor 560, through hole 560C middle section is formed compared with other regions, switchs sensitivity highest.Accordingly, pass through The center of proximity switch 560 of the finger pressing with through hole 560C of user, finger contact sensitivity highest part can be made.
Proximity transducer 560 shown in Figure 51 and Figure 52 is that electrode is used in electrostatic touch (contact), and is:For in Figure 49 and Front (preceding surface) direction of left-hand door 21 and right door 22 shown in Figure 50, human body or object are being detected e.g., from about at 100mm Close electrostatic capacitive testing agency.The proximity transducer 560 is in a part for the human body of user, specifically such as finger When close, the close of the finger is detected.Although proximity transducer 560 be electrostatic capacity type touch sensor but it is also possible to be The touch sensor of the touch sensor of mutual capacitance mode or self capacitive way.
For mutual capacitance mode, it is made up of 1 sender electrode and 1 receiving electrode, is provided when to sender electrode During electric current, electromagnetic field is produced, electromagnetic field is received by receiving electrode.Such as the finger of human body is close to the detection of proximity transducer 560 During region, a part for electromagnetic field is received by absorption and by receiving electrode, therefore the energy being detected is reduced, and thus, is approached Sensor 560 is capable of detecting when the close of finger.
For self capacitive way, the electrode (proximity transducer 560) with stray capacitance needs 1.Electrode (connects Nearly sensor 560) stray capacitance by the electric conductor (hand of human body positioned at the electrode (proximity transducer 560) and around it Refer to) between effect of parasitic capacitance.When the finger of human body is close to proximity transducer 560, influenceed by parasitic capacitance, stray capacitance Value increase, by measuring the increased stray capacitance, proximity transducer 560 is capable of detecting when the close of finger.
As shown in Figure 51 and Figure 52, proximity transducer 560 is created as the switch for the oblong-shaped for example longitudinally grown, slit 574th, 575 are formed as surrounding electrode around proximity transducer 560.As shown in figure 52, from the back side on the slit 574,575 Covered with substrate 598, being arranged at intervals as the LED577 that lighting device works, there have to be multiple.
Wherein, 4 LED577 corresponding with 4 corner 576R of slit 574,575 in multiple LED577 be configured at from The position in the outside of the slit 576 detached in slit 576.
As shown in figure 52, the one end of proximity transducer 560 is linked by linking portion 560A and configuration section 572, is connect The other end of nearly sensor 560 is linked by linking portion 560B with configuration section 572.In proximity transducer 560 Through hole 560C of the centre portion formed with electrical connection.Through hole 560C is formed in the middle body of proximity transducer 560 like this, such as Through as explanation, be provided with through hole 560C proximity transducer 560 region part compared with other region parts, detection spirit Sensitivity is high.Due to the finger of user approach and the region part that contacts be proximity transducer 560 middle body, therefore, will be logical Hole 560C is disposed proximate to the middle body of sensor 560.The slit that proximity transducer 560 passes through the configuration section in substrate 574th, in 575 region 572a, electrode is formed in dashed region, is shaped generally as rectangle.In addition, slit 574,575 is not Whole proximity transducer 560 is surrounded, and is created as U-shaped.This results in following composition:Around formation and slit The bridge 572ab of periphery 572b connections, inner and outer is linked up, and substrate does not remain 1 substrate not dividedly.
Guard electrode 570 shown in Figure 51 and Figure 52 is in configuration section 572, and in proximity transducer 560 and intermediate region Be formed as the frame shape of oblong-shaped around part 589.Guard electrode 570 is metallic object, by a pair of short edges electrode part 570A Formed with a pair of long side electrode part 570B.The generation of guard electrode 570 and electromagnetic field opposite direction caused by proximity transducer 560 Electromagnetic field.
Thus, as shown in Figure 49 and Figure 50, electromagnetic field 560P produces in guard electrode 570 caused by proximity transducer 560 Opposite direction electromagnetic field in the presence of, extension be suppressed.Therefore, pressed down by the electromagnetic field caused by the guard electrode 570 Electromagnetic field 560P extension caused by proximity transducer 560 processed, guard electrode 570 play the effective range change machine of detection range The effect of structure, the effective range of the detection range of the effective range change mechanism change human body of the detection range.
Guard electrode 570 made being changed in a manner of constriction such as finger of detection human body it is close when close to biography The detection range of sensor 560, change the effective range of the detection range of proximity transducer 560.Specifically, guard electrode 570 The effective range of the detection range of proximity transducer 560 is changed, as a result, as shown in figure 49, the opening door operation portion 551 of left-hand door 21 Proximity transducer 560 caused by electromagnetic field 560P be directed only to the positive forward direction of proximity transducer 560.Equally, right door Electromagnetic field 560P caused by the proximity transducer 560 of 22 opening door operation portion 552 be directed only to proximity transducer 560 just in face of Fang Fangxiang.
Therefore, as shown in figure 49, electromagnetic field 560P is narrowed down caused by proximity transducer 560 so that will not be as a left side Extended in the X-direction of right direction.
Moreover, as shown in figure 50, electromagnetic field 560P caused by the proximity transducer 560 of the opening door operation portion 551 of left-hand door 21 It is directed only to the positive forward direction of proximity transducer 560.Equally, the proximity transducer 560 of the opening door operation portion 552 of right door 22 Caused electromagnetic field 560P is directed only to the positive forward direction of proximity transducer 560.Therefore, in Figure 50, proximity transducer Electromagnetic field 560P is narrowed down caused by 560 so that will not be extended in the Z-direction as above-below direction.
I.e., the electromagnetic field 560P of the proximity transducer 560 shown in Figure 49 and Figure 50 shows the effective of the detection range of human body Scope, the effective range of the detection range of the human body equivalent to the front different directions with proximity transducer 560 scope (on Under, the scope of left and right extension) different scope.I.e., the effective range of the detection range of human body is at least by proximity transducer 560 The scope of direction different directions by constriction etc. is changed and operated in the operation direction of user as effective range, by This limit effective range, specifically, be except the scope with front different directions at least a portion (to up and down, left and right, after At least a portion of the scope just extended etc.) outside scope.
Figure 54 is to represent control unit 556, opening door operation portion 551,552, enabling drive division 54,55 as door opener etc. Electrical connection block diagram.
As shown in figure 54, control unit 556 is electrically connected to the proximity transducer 560 and protection electricity of opening door operation portion 551,552 Pole 570, enabling drive division 54,55 and multiple LED577 as lighting device.
Control unit 556 causes proximity transducer 560 to keep " high sensitivity " state.Finger is entered as proximity transducer When in the electromagnetic field 560P shown in Figure 49 and Figure 50 of 560 detection zone, Figure 54 control unit 556 is from proximity transducer 560 Finger is received close to the signal SG of proximity transducer 560.
Then, when Figure 54 control unit 556 receives the signal SG from the proximity transducer 560, it is judged as that finger connects Near proximity transducer 560, and stop the energization to guard electrode 570, while by the sensitivity of proximity transducer 560 from " high Sensitivity " is changed to " muting sensitivity " to reduce sensitivity.Also, control unit 556 comes from the proximity transducer 560 receiving Signal SG when, control unit 556 makes LED577 bright lights, to being illuminated around proximity switch 560, thus, by illumination make Float the position of proximity switch 560 so that user can pass through the position of visual confirmation proximity switch 560.
In addition, the effect as LED577 bright lights, shows that therefore, user is able to confirm that due to carrying out bright light by LED577 Operating position, it is not necessary to implementing to represent the printing of the operating position of operating portion as the front panel 21A (or 22A) of glass plate Deng.
In addition, when being transferred to contact proximity transducer 560 close to the state of proximity transducer 560 from finger, close to sensing Device 560 works as contact-making switch, and proximity transducer 560 sends finger to control unit 556 and contacts proximity transducer 560 Activation signal SH.Thus, control unit 556 makes proximity transducer 560 be worked as feeler, makes opening for such as left-hand door 21 Door operation is effective, and control unit 56 can make the action of enabling drive division 54 actually carry out the opening door operation of left-hand door 21.Aforesaid operations Sequentially, for right door 22 and equally.
Thus, user can visually confirm while contact is configured at left-hand door 21 or right door on one side by LED577 illumination The position of proximity switch 560 on the inside of 22 glass surface, so as to open left-hand door 21 or right door 22.
As described above, control unit 556 is by by " high sensitivity " of the sensitivity of proximity transducer 560 from finger when close " muting sensitivity " is switched to, proximity transducer 560 is played a part of feeler.When finger is close to proximity transducer 560, Control unit 556 makes static switching 560 as " proximity transducer " and worked, and therefore, control unit 556 is by by proximity transducer 560 sensitivity is set as " height ", and the function as " proximity transducer " is " effective ".Therefore, control unit 556 does not make to approach Sensor 560 works as " feeler ", therefore proximity transducer 560 causes the conduct of opening door operation portion 551,552 Left-hand door 21, opening (opening door operation) engineering noise of right door 22 of original function.
As described above, making the finger of user, close to proximity transducer 560, finger is entered as proximity transducer 560 During the electromagnetic field 560P of the effective range of human testing scope, proximity transducer 560 is by finger close to notice to control unit 556.Then, in finger close to when being notified to control unit 556 from proximity transducer 560, control unit 556 will be used as close to biography The sensitivity of sensor 560 is set as " low " from " height " switching.Also, control unit 556 make the bright light of proximity transducer 560 show from Closed mode turns into opening, and the position of proximity transducer 560 can be expressed using LED577.Therefore, user can be on one side The position of proximity transducer 560 is visually confirmed, while reliably contacting proximity transducer 560 with finger.Control unit 556 makes to approach Sensor 560 plays a part of " feeler " as original function, therefore, proximity transducer is contacted by using finger 560, the opening operation (opening door operation) of left-hand door 21 or right door 22 becomes " effective ".
The opening operation (opening door operation) of above-mentioned left-hand door 21 and the opening operation (opening door operation) of right door 22 equally, therefore, The description thereof will be omitted.
As shown in Figure 51 and Figure 52, the configuration protection electrode 570 around proximity transducer 560, thus, passed as close The electromagnetic field 560P of the effective range of the human testing scope of sensor 560 is in positive direction (the front side of left-hand door 21 and right door 22 To) and detect in the range of e.g., from about 100mm human hand, finger it is close.Now, people's physical examination as proximity transducer 560 The electromagnetic field 560P for surveying the effective range of scope is limited because of configuration protection electrode 570 so that in above-below direction and left and right Do not extended on direction.
As shown in figure 49, effective model of the human testing scope of proximity transducer 560 is limited for left and right directions (X-direction) The extension enclosed, thus, as shown in figure 49, to make finger close to left-hand door along the track opening left-hand door 21 shown in arrow 21M During 21 proximity transducer 560, the proximity transducer 560 for the right door 22 being closed can not be allowed to detect finger.Equally, will edge Track shown in arrow 22M open right door 22 and make finger close to right door 22 proximity transducer 560 when, can not allow closing The proximity transducer 560 for the left-hand door 21 detects finger.
Therefore, as right door 22 proximity transducer 560 human testing scope effective range electromagnetic field 560P, no It can enter in track when opening the left-hand door 21 as travel mechanism.Equally, as left-hand door 21 proximity transducer 560 people The electromagnetic field 560P of the effective range of body detection range, track when opening the right door 22 as travel mechanism will not be entered It is interior.
Thus, when opening left-hand door 21 or right door 22, the right door 22 of side do not opened but be closed can be prevented Either the proximity transducer 560 of left-hand door 21 accidentally and flase drop measures the finger or left-hand door 21 or right door 22 of user.
In addition, as shown in figure 50, by the human testing model that proximity transducer 560 is limited for above-below direction (Z-direction) The extension for the effective range enclosed, when the plug-type door 23 as travel mechanism is pulled out in the direction of the arrow, as left-hand door 21 Proximity transducer 560 human testing scope effective range electromagnetic field 560P and proximity transducer as right door 22 The electromagnetic field 560P of the effective range of 560 human testing scope will not be entered in track when opening plug-type door 23.
Thus, when opening plug-type door 23, the proximity transducer 560 of left-hand door 21 and approaching for right door 22 can be prevented Sensor 560 is careless and flase drop measures the finger of user or plug-type door 23.
For the size of the guard electrode 570 shown in Figure 51 and Figure 52, size can be such as 30mmx30mm in length and breadth More than.By setting the size of guard electrode 570 like this, contacted in user with such as ancon rather than finger close to sensing Device 560 in the case of opening left-hand door 21 or right door 22, can prevent ancon while contact proximity transducer 560 and protection electricity The both sides of pole 570.Thus, user also can open left-hand door 21 or right door 22 with finger with ancon.
Next, reference picture 55 illustrates the holding structure example of the substrate 553 of left-hand door 21 and right door 22.Figure 55 is to represent left The figure of the holding structure example of the substrate 553 of door 21 and right door 22.Figure 55 (a) is the front view of left-hand door 21 and right door 22, Figure 55 (b) It is the medial extremity face 21T (the medial extremity face 22T of right door 22) for the left-hand door 21 for showing the holding structure for representing substrate 553 The stereogram of construction.Figure 55 (c) is the figure for the example for representing cover 590.
As shown in Figure 55 (a), in the state of left-hand door 21 and right door 22 is closed, the medial extremity face 21T of left-hand door 21 and the right side The medial extremity face 22T of door 22 is closed in opposite directions.The rectangular opening portion 586 of accommodation space part 585 is located at each medial extremity Facial 21T, substrate mounting body 500M accommodation space part 585 are located at the inside of left-hand door 21 and right door 22.Substrate mounting body 500M is inserted into accommodation space part 585 and is contained from opening portion 586.
Closed after substrate mounting body 500M has been stored using cover 590 opening portion 586.In the cover 590 Internal surface configurations have aluminium foil strip, metallic object 591 as iron plate.Metallic object 591 limits and is used as people caused by proximity transducer 560 The electromagnetic field of the effective range of body detection range, and be the change of the effective range for the detection range for changing proximity transducer 560 Mechanism.Metallic object 591 as the effective range change mechanism of detection range is configured at the left-hand door 21 as adjacent travel mechanism Between right door 22.
By the way that metallic object 591 is configured at into cover 590 like this, metallic object 591 is cut between left-hand door 21 and right door 22 Power off magnetic field.Therefore, the electromagnetic field of the proximity transducer 560 of left-hand door 21 and the electromagnetic field of guard electrode 570 will not be to right doors 22 Proximity transducer 560 and the electromagnetic field of guard electrode 570 have an impact.Moreover, the proximity transducer 560 from right door 22 Electromagnetic field and the electromagnetic field of guard electrode 570 will not produce to the proximity transducer 560 of left-hand door 21 and the electromagnetic field of guard electrode 570 It is raw to influence.
Next, reference picture 48~Figure 50 and Figure 54 come illustrate user open such as left-hand door 21 in the case of action example.

Figure 59 is to represent control unit 656, control operation portion 650, opening door operation portion 651,652, opening as door opener The block diagram of the electrical connection of door drive division 54,55.
As shown in figure 59, control unit 656 is electrically connected to control operation portion 650, the 1st substrate 631 and the 2nd substrate 632, opened the door Drive division 54,55.
In the refrigerator 1 shown in Figure 56, in the case where user opens the left-hand door 21 (or right door 22) of refrigerator 1, if It is dim environment, then is difficult to position and the touch controlled key of the proximity transducer 607 (608) of opening door operation portion 651,652 633 position.So, the operation of opening door operation portion 651,652 is difficult in order to improve, as shown in figure 57, in opening door operation The back side of the touch controlled key 633 in portion 651,652 and the back side of proximity transducer 607 (608), are equipped with for providing illumination light LED635 as lighting mechanism.
Therefore, the situation of touch operation is carried out with the touch controlled key 633 of finger clamshell doors operating portion 651,652 in user Under, electrostatic capacitive proximity transducer 607 (or proximity transducer 608) detects that people's is close.Control unit 656 passes from close Sensor 607 (or proximity transducer 608) receives the close signal of notifier, and illuminating LED 635 is according to the finger of control unit 656 Make bright light.
Thus, user can also identify the proximity transducer of opening door operation portion 651,652 under dim environment The position of 607 (608) and the position of touch controlled key 633, the touch controlled key 633 of opening door operation portion 651,652 can be easily operated, Left-hand door 21 (or right door 22) can be opened.
In addition, when proximity transducer 607 (or proximity transducer 608) detect people it is close when, control unit 656 is from connecing Nearly sensor 607 (or proximity transducer 608) receives the close signal of notifier, therefore, the control operation portion shown in Figure 58 650 illuminating LED 665 bright light according to the instruction of control unit 656.
Thus, even if user is under dim environment, the position in control operation portion 650 can be also identified, can be easily Operational control operating portion 650.
User want with finger on glass system front panel 21A, 22A in a non contact fashion clamshell doors operating portion 651, In the case that 652 touch controlled key 633 carries out touch operation, it is preferable that Figure 59 control unit 656 can be by during LED635 bright lights Brightness is divided into multiple ranks.
I.e., when proximity transducer 607 (or proximity transducer 608) detect people it is close when, Figure 59 control unit 656 Make the pico- bright lights of LED635.Then, the touch controlled key in user with finger clamshell doors operating portion 651,652 in a non contact fashion 633 carry out touch operation, and in the case of the opening door operation establishment of left-hand door 21 (or right door 22), Figure 59 control unit 656 makes LED635 complete bright lights improve light quantity.
Afterwards, user make finger depart from touch controlled key 633, control unit 656 cause enabling drive division 54 (or open the door driving Portion 55) act and open left-hand door 21 (right door 22).
Thus, user with the touch controlled key 633 of finger clamshell doors operating portion 651,652 carry out touch operation and left-hand door 21 In the case that the opening door operation of (or right door 22) is set up, to improve light quantity, therefore LED635 becomes complete bright light from glimmer lamp User can pass through the change of the light quantity, i.e. preferably, increase light quantity, visually to confirm the establishment of opening door operation.
In order to such as user to cooling control content change operation and the control operation portion 650 shown in operation diagram 59. Control unit 656 can be set such that the action start time (bright light of the LED665 bright lights in the control operation portion 650 shown in Figure 58 Opportunity) than action start time (bright light opportunity) delay for the LED635 bright lights for making the opening door operation portion 651,652 shown in Figure 57 Predetermined time delay, i.e. both differences.I.e., can change the LED665 in control operation portion 650 illumination mode opportunity and The opportunity of the LED635 of opening door operation portion 651,652 illumination mode.
Such as, can make opening door operation portion 651,652 LED635 bright light opportunity earlier than control operation portion 650 LED665 bright light opportunity.But it is also possible in turn, make the LED665 bright light opportunity in control operation portion 650 earlier than enabling The LED635 of operating portion 651,652 bright light opportunity.
Thus, when proximity transducer 607 (or proximity transducer 608) detect people it is close when, can not only make out The LED635 bright lights in door operation portion 651,652, the LED665 bright lights in control operation portion 650 can also be made.
As shown in figure 56, on left-hand door 21 and right door 22, the position of proximity transducer 607,608 is arranged to compare control operation On the lower, also, proximity transducer 607,608 is respectively arranged at the touch controlled key of opening door operation portion 651,652 for the position in portion 650 Near 633.
Thus, by making finger close to proximity transducer 607 (or proximity transducer 608) in user and contacting close to biography After sensor 607 (or proximity transducer 608), the movement that directly makes finger move down slightly, can contact opening door operation portion 651, 652 touch controlled key 633, therefore easily operated for user.
Then, Figure 60 shows that the proximity transducer 607 in the left-hand door 21 shown in Figure 56 detects the close of user's finger Afterwards, in the case where finger contacts the touch controlled key 633 of opening door operation portion 651, the control operation portion 650 of left-hand door 21 and enabling The example of the situation of the bright light of operating portion 651.
In Figure 60 (a), the finger of user is in the also not state completely close with proximity transducer 607.In the state Under, control unit 656 is in order that the proximity transducer 607 as static switching works as " proximity transducer ", control unit 656 The sensitivity of proximity transducer 607 is set as " height " to improve sensitivity, thus, the function as " proximity transducer " " has Effect ".
In this case, control unit 656 makes the left-hand door 21 of the function as touch controlled key 633 of opening door operation portion 651 Open (opening door operation) engineering noise.Also, control unit 656 makes the bright light in control operation portion 650 show and opening door operation portion 651 Bright light show it is shown in dotted line as, be " closed mode ".Also, the controlling switch (control button) in control operation portion 650 650CS and HOME switches (HOME buttons) 650HS operation (opening door operation) function engineering noise.
Next, Figure 60 (b) shows finger HT close to the state of proximity transducer 607.In this condition, close to sensing Device 607 detects that finger HT's is close, and therefore, control unit 656 is using proximity transducer 607 as the sensitive of " proximity transducer " Degree switches to " low " from " height " and reduces sensitivity to weaken the function of proximity transducer.
Therefore, control unit 656 makes the touch controlled key 633 of opening door operation portion 651 work, and therefore, finger HT is from front panel Surface contact touch controlled key 633 and opening operation (opening door operation) function of left-hand door 21 for carrying out becomes " to have from engineering noise Effect ".
Also, control unit 656 causes the bright light in control operation portion 650 to show and the opening door operation portion of proximity transducer 607 As 651 bright light is shown as shown by the solid line, become " opening ", shown in the LED635 and Figure 58 shown in Figure 57 LED665 for example carries out pico- bright light.I.e., pico- bright light is carried out by the LED665 shown in Figure 58, lighted from behind to control Operating portion 650 is illuminated, and by the LED635 bright lights shown in Figure 57, is lighted from behind and is carried out clamshell doors operating portion 651 and enter Row illumination.
It is preferred that the bright light shows that the time is such as 10 seconds time as defined in bright light, in this 10 seconds periods finger HT not In the case of the touch controlled key 633 for contacting opening door operation portion 651, LED635,665 can also be made to turn off the light again.
Wherein, control unit 656 may be set so that moving for the LED665 bright lights for making the control operation portion 650 shown in Figure 58 The action start time for making LED635 bright light of the start time (bright light opportunity) than making the opening door operation portion 651 shown in Figure 57 is (bright Lamp opportunity) delay predetermined time delay, i.e. both differences.I.e., control unit 656 can change control operation portion 650 The opportunity of the opportunity of LED665 illumination mode and the LED635 of opening door operation portion 651 illumination mode.
Such as, can make opening door operation portion 651 LED635 bright light opportunity earlier than the LED665's in control operation portion 650 Bright light opportunity.But it is also possible in turn, make the LED665 bright light opportunity in control operation portion 650 earlier than opening door operation portion 651 LED635 bright light opportunity.By making bright light opportunity different like this, user can be directed to distinguish control operation portion 650 Position and the mode of position of opening door operation portion 651 shown.
Next, controlling switch 650CS and HOME the switch 650HS in control operation portion 650 operating function are opened, from Engineering noise becomes " effective ".
Then, in Figure 60 (c), show that finger HT contacts the state of the touch controlled key 633 of opening door operation portion 651. In this condition, control unit 656 maintain proximity transducer 607 as the sensitivity of " feeler " that is, the shape of " low " State.Control unit 656 makes the opening operation of the left-hand door 21 of the function as touch controlled key 633 of opening door operation portion 651 (open the door and grasp Make) function maintain " effective " it is constant.
Next, control button (controlling switch) 650CS the and HOME buttons (HOME switches) in control operation portion 650 650HS operating function is opened, and is become " effective ", therefore can operate.
Also, control unit 656 causes the bright light in control operation portion 650 to show and the opening door operation portion of proximity transducer 607 As 651 bright light is shown as shown by the solid line, maintain " opening ".
In such a situation it is preferred that light quantity and proximity transducer 607 that the bright light in Figure 60 (b) control operation portion 650 is shown Opening door operation portion 651 the light quantity that shows of bright light it is smaller, carry out pico- bright light.But contacted in Figure 60 (c) finger HT When, the light quantity that the bright light in control operation portion 650 is shown and the light quantity that the bright light of opening door operation portion 651 is shown carry from pico- bright light Height, lighted with the complete bright light that is carried out by bigger light quantity.
Thus, with the touch controlled key 633 of finger clamshell doors operating portion 651 touch operation is carried out in user and left-hand door 21 is opened In the case that door operation is set up, LED635 becomes complete bright light to improve light quantity from pico- bright light, and therefore, user can be by bright The increase of lamp amount visually confirms that opening door operation has been set up.Also, user can more reliably identify the aobvious of control operation portion 650 Show the display with opening door operation portion 651, and the energy-saving effect of power consumption can be improved.
As described above, make finger HT as shown in Figure 60 (b) close in the case of proximity transducer 607, and Shown in Figure 60 (c) make finger HT contact touch controlled keys 633 in the case of, control unit 656 is in order to be controlled operating portion 650 Illumination and the illumination of opening door operation portion 651, light quantity when can change bright light as described above improve light quantity.
Afterwards, in Figure 60 (d), show the finger HT of user departing from the touch controlled key 633 of opening door operation portion 52 State.In this condition, control unit 656 has the input of the operation signal of the touch controlled key 633 from opening door operation portion 651 Effect, acts enabling drive division 54, thus, carries out the enabling control of corresponding left-hand door 21.Thus, left-hand door 21 can be beaten automatically Open.
Also, control unit 656 causes the bright light in control operation portion 650 to show and the opening door operation portion of proximity transducer 607 As 651 bright light is shown as shown by the solid line, maintain " opening ".Then, the controlling switch in control operation portion 650 650CS and HOME switches 650HS operating function is closed, and becomes engineering noise from " effective ".

Opening door operation portion 551 and opening door operation portion 552 shown in Figure 61 have same construction, are symmetrical still Shape.Figure 64 shows the shape example of the substrate 553 of opening door operation portion 551, still, opening door operation portion 552 and opening door operation portion 551 be substantially same shape, therefore, 64~Figure 66 of reference picture, is carried out with the substrate 553 of opening door operation portion 551 for representative Explanation.
First, reference picture 66, opening door operation portion 551 have:Substrate mounting body 500M, for storing substrate mounting body 500M Be referred to as be open box body plastics accommodation space part 585 and plastics cover 590.In plastics accommodation space The back side 585R of part 585, preferably paste such as aluminium foil as metallic object.Pasted in the inner surface of plastics cover 590 The metallic objects such as aluminium foil 591.Thus, electromagnet caused by the main body side of refrigerator 1 will not have an impact to substrate mounting body 500M sides.
Substrate mounting body 500M has:Plastics shield 599, substrate 553, operate sign board 597, be equipped with display use LED557 LED-baseplate 598.Substrate 553 is electrostatic soft-touch control substrate, is fixed on the front-surface side of shield 599.In substrate 553 front-surface side is configured with operation sign board 597.Display LED-baseplate 598 is fixed with the rear side of shield 599. Multiple LED577 are equipped with the LED-baseplate 598.
In substrate 553 and 597 corresponding position of sign board is operated, formed with left and right slit 574,575.The substrate mounting body 500M is accommodated in accommodation space part 585 by the opening portion 586 of the rectangle insert port as accommodation space part 585 It is interior.The opening portion 586 of accommodation space part 585 is covered part 590 and covered.
As shown in Figure 64 (a) and Figure 65, the substrate 553 of opening door operation portion 551 is rectangle or square, substrate 553 With the back side 553B shown in the surface 553A and Figure 64 (b) shown in Figure 64 (a).Electronic unit is provided with substrate 553 Carry part 571 and proximity transducer 560 and the configuration section of guard electrode 570 572.Opening door operation portion shown in Fig. 1 551 substrate 553 and the substrate 553 of opening door operation portion 552 preferably use symmetrical shape, can be fabricated to universal component.
The carrying part 571 of the electronic unit of back side 553B sides shown in Figure 64 (b) has the 1st stage portion in end portion 553M and the 2nd stage portion 553N.The end portion of the carrying part 571 of the electronic unit of back side 553B sides is formed as step-like.
Also, overleaf on the carrying part 571 of the electronic unit of 553B sides, be equipped with 2 connector component CC1, Electronic units such as CC2, microcomputer (not shown) etc..Connector component CC1 is configured at the 1st stage portion 553M, and connector component CC2 matches somebody with somebody It is placed in the 2nd stage portion 553N.
I.e., connector component CC1 and connector component CC2 is not to be arranged side by side in the horizontal direction, connector component The position that CC1 is installed on the back side 553B of substrate 553 is installed on relative to connector component CC2 the back side 553B of substrate 553 For position, the position of downside is located in Z-direction (above-below direction).Connector component CC1 matches somebody with somebody along the 1st stage portion 553M Put, connector component CC2 configures along the 2nd stage portion 553N.
Thus, because connector component CC1, CC2 position are staggered in the vertical direction, therefore in maintenance by connector When part CC1, CC2 are removed or installed, instrument easy to use dismounts.
Further, since connector component CC1, CC2 position are staggered in the vertical direction, therefore, condense caused water Easily flowed down between connector component CC1, CC2, therefore, it is possible to prevent:Water caused by condensation retains in connector component CC1, CC2 position.Further, since the back side of connector component CC1, CC2 and substrate has interval, therefore, deposited even in water Stay in the case of in incorporating section, connector component CC1, CC2 will not also be got wet by water.
In addition, it is equipped with 2 connector portions on the carrying part 571 of the electronic unit of the back side 553B sides of substrate 553 Part CC1, CC2, electronic unit (not shown) etc., electronic unit is not carried on the surface 553A of substrate 553.As electronic unit For such as noise remove capacitor, signal transacting electricity container, transistor, microcomputer.Because electronic unit is configured at like this The surface 553A of substrate 553, also configure in back side 553B sides, therefore, as shown in Figure 66, operate the inner surface of sign board 597 not Electronic unit can be impacted, can be configured to be tightly engaged into the surface 553A of substrate 553.
Also, the carrying part 571 of the electronic unit in the back side 553B sides of substrate 553 is configured with 2 connector components CC1, CC2, by making connector component CC1, CC2, proximity transducer 560, the configured separate of guard electrode 570, it is therefore prevented that come from Connector component CC1, CC2 influence of noise proximity transducer 560 and guard electrode 570.
It is configured with the configuration section 572 of the surface 553A sides of the substrate 533 shown in Figure 64 (a) as the 1st electrode Proximity transducer 560, the guard electrode 570 as the 3rd electrode, the middle region part 589 as the 2nd electrode.Close to sensing Device 560 is located at the centre of configuration section 572, and guard electrode 570 is located at the outermost of configuration section 572.Middle region part 589 are disposed proximate between sensor 560 and guard electrode 570.Proximity transducer 560, guard electrode 570 and intermediate region portion It is metal electrode to divide 589, still, is electrically insulated from each other.Middle region part 589 as the 2nd electrode aids in proximity transducer 560, there is the function as proximity transducer.Guard electrode 570 changes the effective range that proximity transducer 560 detects.It is close Sensor 560 is not to be made up of multiple electrodes, but is made up of the electrode of 1 block length square shape.Thus, it is possible to using user's profit The shape of touch operation is easily carried out with finger.
In addition, as shown in Figure 64 (b), conduct is configured with the back side 553B corresponding with configuration section 572 of substrate 553 The netted grounding pattern 573 of 4th electrode.Thus, the grounding pattern 573 causes the noise from refrigerator main body not passed to close Electromagnetic field caused by electromagnetic field caused by sensor 560 and guard electrode 570 brings influence.
As shown in Figure 64 (a) and Figure 65, in the middle position of proximity transducer 560 formed with through hole 560C.In the through hole On 560C, as shown in Figure 64 (b), wire pattern 560H is connected with.Wire pattern 560H is connected by linking portion 560A parts It is connected to through hole 560C.Wire pattern 560H is configured to the linking portion 560A's at the position by being used as beyond slit 574,575 Rear side part.Linking portion 560A is explained below.
User presses with finger the behavior of proximity transducer 560 (contact), typically using the center of proximity transducer 560 as What target was carried out, therefore, through hole 560C is formed at the center position of proximity transducer 560.
The reasons why making through hole 560C be formed at the center position of proximity transducer 560 like this, is as follows.I.e., passed for close For sensor 560, through hole 560C middle section is formed compared with other regions, switchs sensitivity highest.Therefore, by using The center of the proximity switch 560 of the finger pressing with through hole 560C at family, finger contact sensitivity highest part can be made.
Proximity transducer 560 shown in Figure 64 and Figure 65 is that electrode is used in electrostatic touch (contact), is used in Figure 62 and figure Front (preceding surface) direction of left-hand door 21 and right door 22 shown in 63, human body or object are e.g., from about being detected at 100mm Close electrostatic capacitive testing agency.A part specifically such as finger of the proximity transducer 560 in the human body of user When close, the close of the finger is detected.Proximity transducer 560 is electrostatic capacity type touch sensor, can use mutual capacitance Mode touch sensor or self capacitive way touch sensor.
For mutual capacitance mode, it is made up of 1 sender electrode and 1 receiving electrode, is provided when to sender electrode During electric current, electromagnetic field is generated, electromagnetic field is received by receiving electrode.Such as the finger of human body is close to the detection of proximity transducer 560 During region, a part for electromagnetic field is received by absorption and by receiving electrode, and the amount of the energy detected is reduced so that close to sensing Device 560 is capable of detecting when the close of finger.
For self capacitive way, the electrode (proximity transducer 560) with stray capacitance needs 1.Electrode (connects Nearly sensor 560) stray capacitance by the electric conductor (hand of human body positioned at the electrode (proximity transducer 560) and around it Refer to) between effect of parasitic capacitance.When the finger of human body is close to proximity transducer 560, is influenceed and caused miscellaneous by parasitic capacitance The value increase of spurious capacitance, by measuring the increased stray capacitance, proximity transducer 560 is capable of detecting when the close of finger.
As shown in Figure 64 and Figure 65, proximity transducer 560 is created as the switch for the oblong-shaped for example longitudinally grown, slit 574th, 575 it is formed in a manner of surrounding electrode around proximity transducer 560.I.e., slit 574,575 is with the close sensing of encirclement Mode around device 560 is formed along the Z direction.Thus, by setting slit 574,575, it is readily apparent that proximity transducer 560 Position.As shown in Figure 65, covered with such as thin transparent film body 576 on the slit 574,575, on thin transparent film body 576 Across interval formed with multiple light-emitting components to be worked as lighting device that is, LED577.
Wherein, as shown in Figure 65, it is corresponding 4 with 4 corner 576R of slit 574,575 in multiple LED577 LED577 is configured at the outer fix drifted out out of slit 574,575.By being arranged such, with 4 corner 576R corresponding 4 Illumination light caused by individual LED577 is irradiated in a manner of it will not be had an impact to slit 574,575.
As shown in Figure 65, the one end of proximity transducer 560 is linked to configuration section 572 by linking portion 560A, connects The other end of nearly sensor 560 is linked to configuration section 572 by linking portion 560B.These linking portions 560A, 560B Enter joining line in a manner of proximity transducer 560 and its peripheral part that is, middle region part 589 to be connected, also referred to as " bridge ".Linking portion 560A, 560B are arranged at the above-mentioned position being configured with beyond LED577 position in a manner of avoiding.By This, linking portion 560A, 560B will not hinder LED577 illumination light.
Proximity transducer 560 central portion formed with electrical connection through hole 560C.Like this in proximity transducer 560 Middle body forms through hole 560C, as already described, is provided with the region part of through hole 560C proximity transducer 560 Compared with other region parts, detection sensitivity is high.The region part that the finger of user is approached and contacted is proximity transducer 560 Middle body, therefore, through hole 560C is disposed proximate to the middle body of sensor 560.
Next, the guard electrode 570 shown in Figure 64 and Figure 65 is illustrated.
Guard electrode 570 is formed as around proximity transducer 560 and middle region part 589 in configuration section 572 The frame shape of oblong-shaped.Guard electrode 570 is metallic object, by a pair of short edges electrode part 570A and a pair of long side electrode parts 570B is formed.The generation of guard electrode 570 and the electromagnetic field of electromagnetic field opposite direction caused by proximity transducer 560.
Thus, as shown in Figure 62 and Figure 63, electromagnetic field 560P extension is by guard electrode caused by proximity transducer 560 The electromagnetic field of opposite direction caused by 570 suppresses.Therefore, suppressed by the electromagnetic field as caused by guard electrode 570 close to sensing Electromagnetic field 560P extension caused by device 560, guard electrode 570 play the detection model of the effective range of change human testing scope The effect for the effective range change mechanism enclosed.
Guard electrode 570 in a manner of constriction such as finger of alteration detection human body it is close when proximity transducer 560 detection range, to change the effective range of the detection range of proximity transducer 560.Specifically, guard electrode 570 becomes Closer to the result of the effective range of the detection range of sensor 560, as shown in Figure 62, the opening door operation portion 551 of left-hand door 21 Electromagnetic field 560P caused by proximity transducer 560 is only channeled to the positive forward direction of proximity transducer 560.Equally, right door Electromagnetic field 560P caused by the proximity transducer 560 of 22 opening door operation portion 552 is only channeled to the front of proximity transducer 560 Forward direction.
Therefore, as shown in Figure 62, electromagnetic field 560P caused by proximity transducer 560 is with not in the lateral direction that is, X-direction The mode constriction of extension.
Also, as shown in Figure 63, electromagnetic field 560P caused by the proximity transducer 560 of the opening door operation portion 551 of left-hand door 21 It is only channeled to the positive forward direction of proximity transducer 560.Equally, the proximity transducer of the opening door operation portion 552 of right door 22 Electromagnetic field 560P caused by 560 is only channeled to the positive forward direction of proximity transducer 560.Therefore, in Figure 63, close to biography Electromagnetic field 560P caused by sensor 560 by not vertically that is, Z-direction extend in a manner of constriction.
I.e., the electromagnetic field 560P of the proximity transducer 560 shown in Figure 62 and Figure 63 shows the effective of the detection range of human body Scope, the scope in the effective range of the detection range of the human body direction different equivalent to from the front of proximity transducer 560 The different scope (in the scope of upper and lower left and right extension).
Then, Figure 67 is to represent control unit 556, opening door operation portion 551,552, the enabling drive division as door opener 54th, the block diagram of 55 etc. electrical connection.
As shown in Figure 67, control unit 556 is electrically connected to the proximity transducer 560 and protection electricity of opening door operation portion 551,552 Pole 570, enabling drive division 54,55, multiple LED577 as lighting device.
Under the control of control unit 556, proximity transducer 560 is held in " high sensitivity " state.Finger enters work For electromagnetic field 560P shown in Figure 62 and Figure 63 of the detection zone of proximity transducer 560 when, Figure 67 control unit 556 is from close Sensor 560 receives the signal SG that finger has approached proximity transducer 560.
Moreover, Figure 67 control unit 556 is judged as finger when receiving the signal SG from the proximity transducer 560 Approached proximity transducer 560, and stopped the energization to guard electrode 570, and by the sensitivity of proximity transducer 560 from " high sensitivity " is changed to " muting sensitivity " to reduce sensitivity.Also, control unit 556 comes from the proximity transducer receiving During 560 signal SG, control unit 556, to being illuminated around proximity switch 560, utilizes illumination by making LED577 bright lights The position of proximity switch 560 is set to float so that user can be with the position of visual confirmation proximity switch 560.
Then, in finger from the state contacts proximity transducer 560 close to proximity transducer 560 when, proximity transducer 560 Worked as contact-making switch, proximity transducer 560 sends the contact that finger contacts proximity transducer 560 to control unit 556 Signal SH.Thus, control unit 556 makes proximity transducer 560 be worked as feeler, grasps the enabling of such as left-hand door 21 Make effectively, control unit 56 can make enabling drive division 54 act and actually carry out the opening door operation of left-hand door 21.For right door 22 Speech, aforesaid operations order are same.
Thus, user by the illumination caused by LED577 while visually confirm to be configured at left-hand door 21 or right door while touching The position of proximity switch 560 on the inside of 22 glass surface, so as to open left-hand door 21 or right door 22.
As described above, control unit 556 is by by " high sensitivity " of the sensitivity of proximity transducer 560 from finger when close " muting sensitivity " is switched to, proximity transducer 560 is worked as feeler.When finger is close to proximity transducer 560, Control unit 556 is in order that static switching 560 works as " proximity transducer ", and control unit 556 is by the spirit of proximity transducer 560 Sensitivity is set as " height ", thus, the function " effective " as " proximity transducer ".Therefore, control unit 556 does not make proximity transducer 560 work as " feeler ", and therefore, proximity transducer 560 causes the original work(of conduct of opening door operation portion 551,552 Left-hand door 21, opening (opening door operation) engineering noise of right door 22 of energy.
As described above, make the finger of user close to proximity transducer 560, when finger is entered as proximity transducer 560 Human testing scope effective range electromagnetic field 560P when, proximity transducer 560 is by finger close to notice to control unit 556.Then, when from proximity transducer 560 by finger close to notice to control unit 556 when, control unit 556 is set, and is made The sensitivity for obtaining proximity transducer 560 switches to " low " from " height ".Also, control unit 556 causes the bright light of proximity transducer 560 Display becomes opening from closed mode so that the position of proximity transducer 560 can be expressed by LED577.Therefore, user The position of proximity transducer 560 can be visually confirmed on one side, while reliably contacting proximity transducer 560 with finger.Control unit 556 make proximity transducer 560 be worked as original function that is, " feeler ", therefore, close by being contacted by finger The opening operation (opening door operation) of sensor 560, left-hand door 21 or right door 22 becomes " effective ".
The opening operation (opening door operation) of above-mentioned left-hand door 21 equally, is omitted with the opening operation (opening door operation) of right door 22 Its explanation.
As shown in Figure 64 and Figure 65, the configuration protection electrode 570 around proximity transducer 560, thus, passed as close The electromagnetic field 560P of the effective range of the human testing scope of sensor 560 is in positive direction (the front side of left-hand door 21 and right door 22 To), the close of human hand or finger is detected in the range of e.g., from about 100mm.Now, the human body as proximity transducer 560 The electromagnetic field 560P of the effective range of detection range is limited by configuration protection electrode 570 so that in above-below direction and a left side Right direction is without extension.
By limiting the human testing scope of proximity transducer 560 in left and right directions (X-direction) like that as shown in Figure 62 The extension of effective range, as shown in Figure 62, to make finger close to a left side along the track shown in arrow 21K to open left-hand door 21 During the proximity transducer 560 of door 21, the proximity transducer 560 for the right door 22 being closed can not be allowed to detect finger.Equally, Along the track shown in arrow 22K open right door 22 and make finger close to right door 22 proximity transducer 560 when, can not allow pass The proximity transducer 560 for the left-hand door 21 that closed detects finger.
Therefore, as right door 22 proximity transducer 560 human testing scope effective range electromagnetic field 560P not It can enter in track when opening the left-hand door 21 as travel mechanism.Equally, as left-hand door 21 proximity transducer 560 people The electromagnetic field 560P of the effective range of body detection range will not be entered in track when opening the right door 22 as travel mechanism.
Thereby, it is possible to prevent from opening left-hand door 21 or during right door 22, the right door 22 for the side do not opened and be closed or The 560 careless flase drop of proximity transducer of person's left-hand door 21 measures the finger or left-hand door 21 or right door 22 of user.
In addition, as shown in Figure 63, by the human testing scope that proximity transducer 560 is limited in above-below direction (Z-direction) Effective range extension, when pulling out push-pull door 23 as travel mechanism along the direction of arrow, as connecing for left-hand door 21 The electromagnetic field 560P of the effective range of the human testing scope of nearly sensor 560 and the proximity transducer 560 as right door 22 The electromagnetic field 560P of the effective range of human testing scope will not be entered in track when opening push-pull door 23.
Thus, when opening push-pull door 23, can prevent left-hand door 21 proximity transducer 560 and right door 22 close to biography 560 careless flase drop of sensor measures the finger or push-pull door 23 of user.
Guard electrode 570 shown in Figure 64 (a) and Figure 65 is as described above, guard electrode 570 is metallic object, by a pair of short edges Electrode part 570A and a pair of long side electrode part 570B are formed.Such as, when attachment of moisture is before the left-hand door 21 shown in Figure 61 Panel 21A, the moisture are attached to the front panel 21A of the position of guard electrode 570 always, so as to guard electrode 570 because of moisture and When detecting the change of electrostatic capacitance, the enabling drive division caused by the control unit 556 shown in Figure 67 makes proximity transducer 560 (is opened Door gear) 54,55 door opening action it is invalid.
Specifically, the front panel 21A of left-hand door 21 surface or right door 22 are wiped using wet rag in such as user Front panel 22A surface when, if guard electrode 570 detects moisture, proximity transducer 560 perceived wet rag and As opening, even if so, the control unit 556 shown in Figure 67 passes through the enabling drive division caused by making proximity transducer 560 The door opening action engineering noise of (door opener) 54,55, it is also possible that left-hand door 21 or right door 22 will not be battered out.Thus, prevent Left-hand door 21 is stopped or right door 22 is opened accidentally.
In addition, control unit 556 makes to connect when user with proximity transducer 560 is contacted again after finger contact protection electrode 570 The door opening action engineering noise of enabling drive division (door opener) 54,55 caused by nearly sensor 560.And then control unit 556 with Family is with proximity transducer 560 is contacted while finger contact protection electrode 570 when, the enabling caused by making proximity transducer 560 is driven The door opening action engineering noise of dynamic portion (door opener) 54,55.
Thus, it is therefore prevented that in the case where the flase drop of guard electrode 570 measures human body, left-hand door 21 or right door 22 are beaten accidentally Open.
As shown in Figure 61, control operation portion 650 is provided with the inside of the front panel 21A of left-hand door 21, in control operation portion 650 bottom is provided with opening door operation portion 551.Therefore, in control operation portion 650 and the proximity transducer of opening door operation portion 551 Position between 560, it is configured with the short side electrode part 570A of the guard electrode 570 of opening door operation portion 551.In Figure 64 and Figure 65 It is also shown for short side electrode part 570A.
Thus, when the control operation portion 650 on the front panel 21A of left-hand door 21 surface is wiped with wet rag in such as user, The water drips along front panel 21A, and reaches guard electrode 570.In this case, the short side electrode portion of guard electrode 570 When point 570A detects moisture, proximity transducer 560 has perceived wet rag and has become opening, even if so, Tu67Suo The control unit 556 shown also can be by making the door opening action of the enabling drive division (door opener) 54 caused by proximity transducer 560 Engineering noise, and left-hand door 21 will not be battered out.Thus, it is therefore prevented that left-hand door 21 is opened accidentally.
In addition, the interval HF of the horizontal electrode gap of guard electrode 570 shown in Figure 65 and the electrode gap of longitudinal direction It is bigger than the finger HT of human body width MF to be spaced RF.The interval HF of the horizontal electrode gap of guard electrode 570 and the electricity of longitudinal direction The interval RF of clearance between poles can preferably be selected in the range of 15mm~75mm.Thus, finger HT is made to be passed close to close in user Sensor 560 and when contacting, can prevent the careless contact protection electrodes 570 of finger HT.
In addition, the interval RF of the interval HF of the horizontal electrode gap of guard electrode 570 and the electrode gap of longitudinal direction is i.e. The ancon of the bending of human body is set to encounter the size that will not also touch guard electrode 570.The horizontal electricity of these guard electrodes 570 The interval RF of the interval HF of clearance between poles and the electrode gap of longitudinal direction can be selected in the range of such as 30mm~75mm.Pass through this Sample sets the size of guard electrode 570, and pot or plate etc. are with the hands held even in user, be with the ancon rather than hand of bending Abutment proximity transducer 560 in the case of opening left-hand door 21 or right door 22, can also prevent ancon while contact is close Sensor 560 and the both sides of guard electrode 570.Thus, user also can open left-hand door 21 or right door with finger with ancon 22。
Then, reference picture 68 illustrates the holding structure example of the substrate 553 of left-hand door 21 and right door 22.Figure 68 is to represent left-hand door 21 and right door 22 substrate 553 holding structure example figure.Figure 68 (a) is the front view of left-hand door 21 and right door 22, and Figure 68 (b) is Represent the vertical of the medial extremity face 21T (the medial extremity face 22T of right door 22) of the left-hand door 21 of the holding structure of substrate 553 construction Body figure.Figure 68 (c) is the figure for the example for representing cover 590.
As shown in Figure 68 (a), in the state of left-hand door 21 and right door 22 is closed, the medial extremity face 21T of left-hand door 21 and the right side The medial extremity face 22T of door 22 is toward each other.The rectangular opening portion 586 of accommodation space part 585 is located at each medial extremity Facial 21T, substrate mounting body 500M accommodation space part 585 are located at the inside of left-hand door 21 and right door 22.Substrate mounting body 500M is contained in a manner of being inserted into from opening portion 586 in accommodation space part 585.
Wherein, in the case of being stored substrate mounting body 500M is inserted into accommodation space part 585 like this, such as Shown in Figure 66, the side of configuration section 572 of substrate 553 is in the side of cover 590, and the side of carrying part 571 of electronic unit is from electronics Carrying part 571 side of part is inserted into opening portion 586 and reaches the inboard of accommodation space part 585.
So, proximity transducer 560 and guard electrode 570 are configured at the surface of substrate 553, are set at the back side of substrate 553 The carrying part 571 of electronic unit is equipped with, in the state of substrate 553 is held in left-hand door 21, the carrying part of electronic unit 571 are located at the opposite side of configuration section 572 of the substrate 553 of the side of opening portion 586 as insert port.
Thus, in the case where being inserted into accommodation space part 585 and storing by substrate mounting body 500M, operator's energy The 1st stage portion 553M and the 2nd stage portion 553N of enough carrying parts 571 for visually confirming electronic unit on one side position, on one side Substrate mounting body 500M is inserted into accommodation space part 585, therefore, it is possible to prevent from substrate mounting body 500M being mistakenly inserted Direction of insertion.
Closed after substrate mounting body 500M has been stored using cover 590 opening portion 586.In the cover 590 Internal surface configurations have metallic object 591 as aluminium foil strip or iron plate.Metallic object 591 limits conduct caused by proximity transducer 560 The electromagnetic field of the effective range of human testing scope, it is the change of the effective range for the detection range for changing proximity transducer 560 Mechanism.Metallic object 591 as the effective range change mechanism of detection range is configured at the left-hand door as adjacent travel mechanism Between 21 and right door 22.
By the way that metallic object 591 is configured at into cover 590 like this, metallic object 591 hides between left-hand door 21 and right door 22 Power off magnetic field.Therefore, the electromagnetic field of the proximity transducer 560 of left-hand door 21 and the electromagnetic field of guard electrode 570 will not be to right doors 22 Proximity transducer 560 and the electromagnetic field side of guard electrode 570 bring influence.In addition, the proximity transducer 560 from right door 22 Electromagnetic field and the electromagnetic field of guard electrode 570 will not be to the proximity transducer 560 of left-hand door 21 and the electromagnetic field of guard electrode 570 Bring influence in side.
Next, the action example in the case that reference picture 61~Figure 63 and Figure 67 opens such as left-hand door 21 to user is said It is bright.
Make the proximity transducer 560 of the side of left-hand door 21 shown in finger close to Figure 62 and Figure 63 in user, and enter Figure 62 During with the electromagnetic field 560P of the effective range as human testing scope shown in Figure 63, the proximity transducer of high sensitivity state 560 detect that finger has approached proximity transducer 560.Thus, Figure 67 control unit 556, which receives, represents that finger has approached biography The signal SG of sensor 560.
Then, Figure 67 control unit 556 stops to guard electrode 570 according to the signal SG from the proximity transducer 560 Energization, and control unit 556 is reduced close to the sensitivity of sensor 560 so that is changed to from " high sensitivity " " low sensitive Degree ".Moreover, control unit 556 is illuminated by making LED577 bright lights to proximity switch 560, proximity switch 560 can be expressed Position, user can visually confirm the position of proximity switch 560.
Then, when finger contacts proximity transducer 560, the proximity transducer 560 of muting sensitivity is as opening a left side The soft-touch control (contact-making switch) of door 21 works, and the activation signal SH that finger is contacted to proximity transducer 560 is sent to figure 67 control unit 556.Thus, control unit 556 makes the opening door operation of left-hand door 21 effective, and control unit 556 makes enabling drive division 54 dynamic Make, therefore left-hand door 21 can be made to open the door.
In addition, user open right door 22 in the case of action example and above-mentioned opening left-hand door 21 in the case of action example phase Together, therefore omit the description.
So, in the proximity transducer 560 that user is worked by the use of finger contact as feeler, control unit 556 Left-hand door 21 or right door 22 can be automatically opened up.
When user only contacts proximity transducer 560, control unit 556 makes proximity transducer 560 (be connect as touch sensor Touch sensor) work, make the opening door operation " effective " of left-hand door 21, thus carry out the opening door operation of left-hand door 21.This is for right door It is also the same for 22.
In the case of proximity transducer 560 and the both sides of guard electrode 570 that user contacts shown in Figure 64 accidentally, control Portion 556 does not make proximity transducer 560 be worked as feeler, and makes the opening door operation engineering noise of left-hand door 21, thus, no Carry out the opening door operation of left-hand door 21.Thus, control unit 556 touches proximity transducer 560 accidentally in user such as ancon In the case of the both sides of guard electrode 570, make the opening door operation engineering noise of left-hand door 21, the opening door operation of left-hand door 21 can be forbidden.
Also, even in causing proximity transducer 560 shown in Figure 64 and the both sides of guard electrode 570 to examine because water droplet adheres to In the case of measuring, control unit 556 does not make proximity transducer 560 be worked as feeler yet, and makes opening for left-hand door 21 Door operation engineering noise, thus, without the opening door operation of left-hand door 21.Above-mentioned opening door operation is forbidden for right door 22 Equally.
In addition, be not the refrigerator of opposite opened but in the case of the refrigerator of single open-type, human body or object come refrigerator Side in the case of, can prevent the careless flase drop of proximity transducer of door from measuring the human body or object.
In addition, proximity transducer 560 shown in Figure 64 detect the finger HT of user close " proximity test pattern " and " the electrostatic touch mode " that is worked as feeler that proximity transducer 560 detects the finger HT of user contact can be with Switch over as follows.
As shown in Figure 64, connect as the proximity transducer 560 of the 1st electrode and as the middle region part 589 of the 2nd electrode It is connected to the microcomputer 599C of control unit 556.
Situation as switch mode includes:When switching to " electrostatic touch mode " from above-mentioned " proximity test pattern ", With from " electrostatic touch mode " switch to " proximity test pattern " when.
When switching to " electrostatic touch mode " from " proximity test pattern ", proximity transducer 560 detects finger HT's After, proximity transducer 560 of the microcomputer 599C cut-outs as the 1st electrode and the middle region part 589 as the 2nd electrode Inside connection, works only proximate to electrostatic touch sensor of the sensor 560 as " electrostatic touch mode ".
On the contrary, from " electrostatic touch mode " switch to " proximity test pattern " when, finger HT depart from proximity transducer 560, Pass through stipulated time, such as 10 seconds from " electrostatic touch mode ", or from open the door by close the door etc. carried out reset when, microcomputer 599C be connected as the proximity transducer 560 of the 1st electrode with the inside of the middle region part 589 as the 2nd electrode.
Then, Figure 74 (a), 74 (b) show the example of scenario described below:For making finger HT contact the figure of the 32nd embodiment The proximity transducer 560 as the 1st electrode shown in 51 and Figure 52 and in the case of opening the door 21 in left side, carry out as the 1st The switching of the proximity transducer 560 of electrode and the middle region part 589 as the 2nd electrode, the control operation portion 650 of left-hand door 21 With the bright light of proximity transducer 560.The situation is also the same for the door 22 on right side.
In Figure 74 (a), the finger of user is also not completely close to the state of proximity transducer 560.In a state, control In order that the proximity transducer 560 as static switching works as " proximity transducer ", control unit 556 makes to approach in portion 556 Sensor 560 is opened and the sensitivity of proximity transducer 560 is set as into " height " to improve sensitivity, thus, as " close to biography The function " effective " of sensor ".Also, control unit 556 makes middle region part 589 connect and by the spirit of middle region part 589 Sensitivity is set as " height " to improve sensitivity, thus, the function " effective " as " proximity transducer ".
In this case, control unit 556 makes the left-hand door 21 of the function as touch controlled key 633 of opening door operation portion 651 Open (opening door operation) engineering noise.Also, control unit 556 makes the bright light in control operation portion 650 show and proximity transducer 560 Bright light is shown as " closed mode ".Then, controlling switch (control button) 650CS and the HOME switch in control operation portion 650 (HOME buttons) 650HS operation (opening door operation) function engineering noise.
Then, show finger HT close to the state of proximity transducer 560 in Figure 74 (b).In this condition, close to biography Sensor 560 detects that finger HT's is close, and therefore, control unit 556 makes proximity transducer 560 be opening, will approach sensing The sensitivity as " proximity transducer " of device 560 switches to " low " to reduce sensitivity from " height ", weakens proximity transducer Function, disconnect middle region part 589.
Therefore, control unit 556 makes proximity transducer 560 as feeler and worked, and therefore, finger HT is from front panel The proximity transducer 560 that is worked as feeler of surface contact, the opening operation of the left-hand door 21 thus excited (opens Door operation) function becomes " effective " from engineering noise.
Also, control unit 556 causes the LED in control operation portion 650 bright light to show with the LED's of proximity transducer 560 Bright light, which is shown, turns into " opening ", as both LED lighting lamp states, such as carries out pico- bright light.I.e., shown in Figure 58 The pico- bright lights of LED665, thus, control operation portion 650 is illuminated from behind and lighted, the LED577 shown in Figure 52 is pico- Bright light, the proximity transducer 560 to be worked as feeler is illuminated from behind from there through slit 574,575 and It is luminous.In such a situation it is preferred that the bright light shows that the time is such as 10 seconds time as defined in bright light, during this 10 seconds, In the case where finger HT does not contact the proximity transducer 560 to be worked as feeler, can also cause again LED635,577 are turned off the light.
Wherein, control unit 556 can be set as:Make the action of the LED665 bright lights in the control operation portion 650 shown in Figure 58 Action start time (the bright light of LED577 bright light of the start time (bright light opportunity) than making the proximity transducer 560 shown in Figure 52 Opportunity) delay predetermined time delay, i.e., make both different.I.e., control unit 556 can change control operation portion 650 The opportunity of the opportunity of LED665 illumination mode and the LED577 of proximity transducer 560 illumination mode.Such as, proximity transducer 560 LED577 bright light opportunity can be earlier than the LED665 in control operation portion 650 bright light opportunity.But on the contrary, can also So that bright light opportunity of the LED665 in the control operation portion 650 bright light opportunity earlier than the LED577 of proximity transducer 560.Pass through picture So make bright light opportunity different, user can be directed to, by the position in control operation portion 650, proximity transducer 560 and intermediate region The position of part 589 makes a distinction display.
Then, controlling switch 650CS and HOME the switch 650HS in control operation portion 650 operating function are opened, from " nothing Effect " becomes " effective ".
Then, in Figure 74 (c), the proximity transducer 560 that finger HT contacts are worked as feeler is shown State.In this condition, control unit 556 maintains the sensitivity as " feeler " that is, " low " of proximity transducer 560 State.Control unit 556 makes the function of the proximity transducer 560 to be worked as feeler that is, the opening of left-hand door 21 is grasped Making (opening door operation) function maintains " effective " constant.Also, the bright light shape that the bright light as the LED of proximity transducer 560 is shown State, control unit 556 change illumination mode, become common bright light from pico- bright light.
I.e., the LED665 shown in Figure 58 carries out common bright light, thus, from behind to control operation portion 650 with brighter Bright mode is illuminated and lighted, also, LED577 shown in Figure 52 carries out common bright light, thus, by slit 574, 575 are illuminated to the proximity transducer 560 to be worked as feeler and lighted in a manner of more becoming clear from behind. I.e., in Figure 74 (c) finger HT contacts, light quantity and the bright light of proximity transducer 560 that the bright light in control operation portion 650 is shown The light quantity of display rises to usual bright light from glimmer lamp, is lighted with the complete bright light based on bigger light quantity progress, thus, approached The bright light of sensor 560, which is shown, to be become more to become clear.Control unit 556 makes the LED in control operation portion 650 lighting lamp state also from micro- Glimmer lamp becomes common bright light.
Then, control button (controlling switch) 650CS and HOME buttons (HOME switches) 650HS in control operation portion 650 Operating function open, be " effective ", therefore can operate.
Thus, user with finger to proximity transducer 560 carry out touch operation and cause left-hand door 21 opening door operation into In the case of vertical, LED577 becomes complete bright light from pico- bright light and improves light quantity, and therefore, user can pass through the increasing of bright light amount Add and visually confirm that opening door operation has been set up.Also, user can more reliably identify control operation portion 650 display and LED577 display, and the energy-saving effect of power consumption can be improved.
As described above, shown in such as Figure 74 (b), finger HT contacts close in the case of proximity transducer 560 in finger HT During touch controlled key 633 shown in Figure 74 (c), control unit 556 is controlled illumination and the proximity transducer 560 of operating portion 650 Illumination, therefore, it is possible to change light quantity when improving bright light as described above.
Afterwards, in Figure 74 (d), show user finger HT depart from as feeler work close to sensing The state of device 560.In this condition, control unit 556 makes the input of the operation signal from proximity transducer 560 effective, to make out Door drive division 54 acts, and thus, carries out the enabling control of corresponding left-hand door 21.Thus, left-hand door 21 can automatically open up.Then, Control unit 556 makes the function engineering noise of the proximity transducer 560 to be worked as feeler.
Also, control unit 556 make the bright light in control operation portion 650 show and the slit of proximity transducer 560 574,575 at LED577 bright light show as shown by the solid line as, maintain " opening ".Then, the control in control operation portion 650 is opened The operating function for closing 650CS and HOME switches 650HS is closed, and becomes engineering noise from " effective ".
As described above, as the opening action of the left-hand door 21 illustrated with reference picture 74, for using the right door shown in Figure 56 The opening action of the right door 22 of 22 opening door operation portion 652 can also be carried out.
Next, reference picture 75 come illustrate proximity transducer 560 detect finger contact principle.Figure 75 is to represent close Sensor 560 detects the circuit diagram of the principle of finger HT contact.
Contact detection circuit 888 shown in Figure 75 has:Proximity transducer 560, adjustment as feeler (Cx) Capacitor (Cmod) 889, clock generating source 890, IDAC (electric current output digital analog converter) 891, latch 892, timer 893rd, AND (with) circuit 894, counter 895.IDAC891 make every time identical electric current in a pulsed fashion multi-reflow to conduct The proximity transducer (Cx) 560 and adjustment capacitor (Cmod) 889 of feeler, make electric charge gradually lodge in and are passed as contact The proximity transducer (Cx) 560 and adjustment capacitor (Cmod) 889 of sensor.To the proximity transducer as feeler (Cx) 560 and adjustment capacitor (Cmod) 889 turn into current potential untill continue to accumulate electric charge, counter 895 is to until in adjustment electric capacity The number of pulse untill the accumulation regulation electric charge of device (Cmod) 889 is counted.
During finger HT proximity transducers 560 of the contact as feeler (Cx), as feeler close to biography The electrostatic capacitance increase of sensor (Cx) 560, therefore, the electric charge for flowing to adjustment capacitor (Cmod) 889 and accumulating tails off, to electric charge The time is spent untill adjustment capacitor (Cmod) 889 is completed to accumulate, therefore, the pulse that counter 895 is counted Count number increases (slope is gentle), therefore, the result is that the displacement of slope changes.Judged with the difference of the displacement of the slope The presence or absence of finger.I.e., the count number of the pulse counted in counter 895 reaches super from common count number (basis counts) When crossing the value of certain threshold value, control unit 556 is judged as that finger HT contacts the proximity transducer as feeler (Cx) 560。
Then, the change side of sensitivity when contacting proximity transducer 560 as feeler (Cx) to finger HT Method illustrates.
As the variation of sensitivity, when reducing IDAC891 current value, if lodging in proximity transducer (Cx) 560 quantity of electric charge is identical, then the time for end of charging lengthens, and becomes gentle.In the time slack that flattens, judged with same threshold In the case of, sensitivity is increased.
Under the gentle state of slope (current value is small), from finger not in contact with state-detection abutment in one's hands shape During state, the change increase of slope, threshold value, sensitivity increase are well over.In addition, in the not gentle state of slope (current value is big) Under, from finger not in contact with state-detection abutment in one's hands state when, the change of slope reduces, it is difficult to more than threshold value, Sensitivity is small.
I.e., compared with the state for exceeding threshold value first when being contacted with whole finger and detecting, reduce current value, by This, even if only being also capable of detecting when to come, it is possible to increase sensitivity with finger tip contacts.Although in addition, also can by reducing threshold value Sensitivity is improved, still, due to the problem of noise can be also detected be present, therefore, with above-mentioned sensitivity variation Change sensitivity.
Then, Figure 76 is the figure for the essential structure for representing proximity transducer.
As shown in Figure 76, proximity transducer 560 and copper are grounded 569 between coating 560R and dielectric layer 560D, The connecing when electric capacity after the electrostatic capacitance CP and finger HT of proximity transducer 560 itself electrostatic capacitance CF additions contacts for finger The electrostatic capacitance CX of nearly sensor 560.
In finger HT carries out the action of electrostatic touch to proximity transducer 560, approaching during finger HT contacts is detected The electrostatic capacitance CX of sensor 560 change.In addition, in actions of the detection finger HT close to proximity transducer 560, detect The electrostatic capacitance CP of proximity transducer 560 itself when finger is close change.When finger is close, by changing close to sensing The electrostatic capacitance CP of device 560 itself, change close to distance (sensitivity).When close, detect finger close to caused small Electrostatic capacitance CP change.Electrostatic capacitance CP is the electric field in 3-dimensional direction, when finger is in electric field, is slightly changed, by This, the electrostatic capacitance CX of whole proximity transducer is changed, and the detection of finger can be carried out by above-mentioned detection.
Next, Figure 77 be for shown in Figure 74 as the 1st electrode that is, feeler work close to sensing Device 560 and the middle region part 589 as the 2nd electrode, illustrate close to handover operation when pattern and electrostatic touch mode Figure.
As shown in Figure 77, the proximity transducer 560 and the electricity of conduct the 2nd to be worked as the 1st electrode that is, feeler The middle region part 589 of pole is connected to multiplexer 556R.Multiplexer 556R is according to the microcomputer of control unit 556 556M instruction, proximity transducer 560 is carried out internal connection with middle region part 589, or internal connection can be released.
(1) from the switching action switched close to pattern to electrostatic touch mode when
In the case where carrying out from the switching action switched close to pattern to electrostatic touch mode, such as Figure 74 (a)~Figure 74 (b) shown in, finger HT is close to proximity transducer 560, when proximity transducer 560 detects finger HT, from close to pattern switching to Electrostatic touch mode.I.e., according to Figure 77 microcomputer 556M instruction, multiplexer 556R makes proximity transducer 560 and centre Region part 589 becomes the releasing state of internal connection, cut-out proximity transducer 560 and intermediate region portion from internal connection state Divide 589 connection.Thus, only proximity transducer 560 uses as electrostatic contact sensor, thus, middle region part 589 disconnect, and are not used.
(2) during from electrostatic touch mode to the switching action close to pattern switching
On the contrary, carrying out from electrostatic touch mode to the situation of the switching action close to pattern switching, touched from such as electrostatic Pattern is touched by 10 seconds, or the situation that closing for passing through door from the opening of door etc. is reset.In this case, according to microcomputer 556M instruction, the releasing state that multiplexer 556R is connected from proximity transducer 560 with the inside of middle region part 589 Internal connection state is returned to, proximity transducer 560 and middle region part 589 can be connected.
And then 48~Figure 50 of reference picture.In Figure 48~Figure 50, the He of proximity transducer 560 as the 1st electrode is shown Modification as the proximity test effective range of the middle region part 589 of the 2nd electrode.
The proximity test effective range of proximity transducer 560 when using only proximity transducer 560 as the 1st electrode, It is roundlet HC1 scope.Then, by the basis of proximity transducer 560 and being used as the middle region part of the 2nd electrode 589, the proximity test effective range of proximity transducer 560 can extend model in a manner of expanding to great circle HC2 from roundlet HC1 Enclose.
But when to extend proximity test effective range like this, in the proximity test of great circle HC2 proximity transducer Under effective range, adjacent door 21 (or door 22) as travel mechanism, be positioned over door rear side door compartment water bottle The instruction for opening door is sent etc. the proximity test effective range that can react on proximity transducer 560, it is possible to so that being not desired to beat The door for opening side is opened accidentally.
Therefore, in order to carry out the change of the proximity test effective range of proximity transducer 560, as the effective model of proximity test The change mechanism enclosed, it is provided with shown in the grounding pattern 573 and Figure 51 (a) as the 4th electrode shown in Figure 78 and Figure 51 (b) Guard electrode 570 as the 3rd electrode.
Figure 78 is the figure for the change close to scope for illustrating proximity transducer 560 and middle region part 589.
As shown in Figure 78, as shown in Figure 51 (b) as in the back side 553B corresponding with configuration section 572 of substrate 553 On be configured with netted grounding pattern 573 as the 4th electrode.The grounding pattern (mesh electrode) 573 covers proximity transducer 560 With the substrate 553 of the rear side of middle region part 589.By making grounding pattern 573 and proximity transducer 560 be identical electricity Pressure, electric field is not formed to grounding pattern 573 from proximity transducer 560 and middle region part 589.Thereby, it is possible to change electric field Scope, the scope for being not desired to be detected by proximity transducer 560 is removed.Electric field from grounding pattern 573 is only to proximity transducer 560 and the direction of middle region part 589 produce electric field, offset from proximity transducer 560 and middle region part 589 towards ground connection The electric field of pattern 573, disappear (elimination) towards the electric field in the back side direction of substrate 553.
Thus, as shown in Figure 78 (a), when configuring the grounding pattern 573 as the 4th electrode at the back side of substrate 553, approach The proximity test scope DL1 of sensor 560 and middle region part 589 can be more than the proximity test scope shown in Figure 78 (b) DL2.Grounding pattern 573 is net metal bucking electrode, compared with Figure 78 (a) and Figure 78 (b), by configuring grounding pattern 573, In Figure 78 (a), the electric field at rear reduces amount corresponding with the scope A shown in Figure 49, or disappears.
In addition, as shown in Figure 51 (a), the guard electrode 570 of frame-type is configured at substrate 553, guard electrode 570 is surrounded and connect Nearly sensor 560 and middle region part 589, thus, the electric field reduction of left and right directions are corresponding with the scope U shown in Figure 49 Amount.Thus, as shown in Figure 48~Figure 50, the proximity test effective range of proximity transducer 560 can be changed to small from great circle HC2 Shape HC3, moreover, as shown in figure 50, amount corresponding with scope V is reduced in above-below direction.
So, the proximity test effective range of proximity transducer 560 is as shown in Figure 50 small shape HC3, on the whole, only The forward direction for having the proximity test scope DL1 of proximity transducer 560 and middle region part 589 is stretched out, can be in distance In the range of carry out proximity test.In addition, even if setting the metallic object 591 shown in Figure 53, it can also electric field is had an effect, have The proximity test effective range of proximity transducer is no more than the function of metallic object 591, can further prevent proximity transducer Caused error detection.
33rd embodiment
