In fig. 33, in step s 11, the advance operative association of user inputs such as keyboard of registration unit 305, touched Template etc., inputs such as " milk ", " egg ", " butter " with the storage shelf of the side of left-hand door 21 and is registered, to the right side in association 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 storage part 300 and the storage shelf of 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：Making close to refrigerator is detected 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 recognizes 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 left-hand door 21 enabling drive division 54 output enabling driving instruction, make enabling drive division 54 move 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, and voice signal is sent to control unit 56, therefore control unit 56 is known Other voice.Thus, in step S17,56 pairs of control unit is accommodated with " fruit juice ", " mustard ", the right door of at least one in " bean curd " The 22 output enabling driving instruction of enabling drive division 55, acts enabling drive division 55.Therefore, in step S18, right door 22 Storing shelf can be automatically turned under the action of enabling drive division 55.

In storage part 300, the storage for for example registering the side of left-hand door 21 for being put into " milk " in association in advance is put Frame, even not knowing the people at the position being put into the refrigerator of " milk ", if saying " milk ", can be automatically turned on a left side 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 times of door is reduced, and improves energy-saving effect.

In addition, in the case of the water tank of ice making is configured with refrigerator, for example being said " water storage ", being put by user Putting the door of water tank side, such as left-hand door 21 will open, and 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, water tank is held and what both hands took even in user's both hands In the case of, such as left side to be opened to store water tank can be also automatically turned on 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, catch handle 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 is opened, can be by making these different doors Opening opportunity open etc. with staggering, prevent door is produced 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, is that speech recognition is come from as obtained from voice recognition sensor NSl, NS2 recognize the language (word) that user sends Sensor NSl, NS2 voice signal.The predetermined language (word) sent as user, can use such as " sesame 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 The word for being not in " open sesame ", and then 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.The voice that control unit 56 provides the triggering started for speech recognition can be set to miscellaneous with refrigerator generation 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 in the different sound of the sound of music etc. played.In addition, when the sound that will be recognized 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 different from the sound that refrigerator is produced, therefore is 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 that user produces etc. is by hole portion 154 Reach voice recognition sensor NS2.The hole portion 154 can be made up of or be made up of multiple holes single hole.By This, voice recognition sensor NS2 can be configured to be built in the bottom of right door 22, and can be reliable by hole portion 154 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 be informed with least one of light, sound, voice user 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 in detection 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 recognized by voice recognition sensor NS1, NS2, and voice signal is notified to control unit 56.Thus, control unit 56 leads to 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 can make respective opening speed different with right door 22.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, it is connected with height measurement sensor 410 on 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 example, 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.

For example, the height values of the user measured in height measurement sensor 410 are the and of left-hand door 21 for reaching 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 The speed for making the left-hand door 21 and right door 22 of upper layer side further to slow down than respective normally open speed is opened.

Thus, it is possible to avoid left-hand door 21 and right door 22 from bumping 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 and right door 22 of upper layer side 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 as " repetition " repeat to urge voice signal of content to be 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 It is secondary to confirm.

In addition, opening the right door 22 of the refrigerating chamber on upper strata in user and 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 is observed, 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 is opened in user and 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, it is connected with proximity transducer 400 on 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, as the opening door operation portion 51 of 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.

As shown in Figure 51 (a) and Figure 52, through hole 560C is formed with the middle position of proximity transducer 560, still, at this On through hole 560C, such as shown in Figure 51 (b), wire pattern 560H is connected with.User presses with finger proximity transducer 560 (contact) Behavior, be typically to be 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, can make finger contact sensitivity highest part.

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, detects human body or object at e.g., from about 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, is provided when to sender electrode 1 sender electrode and 1 receiving electrode During electric current, electromagnetic field is produced, electromagnetic field is received by receiving electrode.Detection of the finger of such as human body close to proximity transducer 560 During region, a part for electromagnetic field is received by absorption 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 of such as long oblong-shaped in longitudinal direction, 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, the LED577 worked as lighting device, which is arranged at intervals, 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 with 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 Centre portion is formed with the through hole 560C of electrical connection.Like this in the middle body formation through hole 560C of proximity transducer 560, 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, in dashed region formation electrode, it is shaped generally as rectangle.In addition, slit 574,575 is not Whole proximity transducer 560 is surrounded, and is created as U-shaped.Constituted this results in following：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 Constituted with long a pair side electrode part 570B.Guard electrode 570 produces the electromagnetic field opposite direction produced with proximity transducer 560 Electromagnetic field.

Thus, as shown in Figure 49 and Figure 50, the electromagnetic field 560P that proximity transducer 560 is produced is produced in guard electrode 570 Opposite direction electromagnetic field in the presence of, extension be suppressed.Therefore, pressed down by the electromagnetic field produced by guard electrode 570 The extension for the electromagnetic field 560P that proximity transducer 560 processed is produced, guard electrode 570 plays 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 changed by way of with constriction such as finger that makes detection human body it is close when close to biography The detection range of sensor 560, changes 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 The electromagnetic field 560P that produces of proximity transducer 560 be directed only to the positive forward direction of proximity transducer 560.Equally, right door The electromagnetic field 560P that the proximity transducer 560 of 22 opening door operation portion 552 is produced be directed only to proximity transducer 560 just in face of Fang Fangxiang.

Therefore, as shown in figure 49, the electromagnetic field 560P that proximity transducer 560 is produced is narrowed down so that will not be used as a left side Extended in the X-direction of right direction.

Moreover, as shown in figure 50, the electromagnetic field 560P of the generation of 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 The electromagnetic field 560P of generation is directed only to the positive forward direction of proximity transducer 560.Therefore, in Figure 50, proximity transducer The 560 electromagnetic field 560P produced are narrowed down 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 with the front different directions of 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 with the scope of front different directions at least a portion (above and below, left and right, after At least a portion of scope etc. of side's extension) outside scope.

Figure 54 be represent control unit 556, opening door operation portion 551,552, as enabling drive division 54,55 of 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 is being received from the proximity transducer 560 Signal SG when, control unit 556 makes LED577 bright lights, to being illuminated around proximity switch 560, thus, by illumination make The position of proximity switch 560 float so that user can be by the position of visual confirmation proximity switch 560.

In addition, as the effect of LED577 bright lights, showing that therefore, user is able to confirm that due to carrying out bright light by LED577 Operating position, it is not necessary to implement to represent the printing of the operating position of operating portion to the front panel 21A (or 22A) as 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 Effectively, control unit 56 can make the action of enabling drive division 54 actually carry out the opening door operation of left-hand door 21 to door operation.Aforesaid operations Sequentially, it is also same for right door 22.

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 passes through " high sensitivity " by 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, therefore, and control unit 556 is by by proximity transducer 560 sensitivity is set as " height ", is " effective " as the function of " proximity transducer ".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, and 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, thus the configuration protection electrode 570 around proximity transducer 560, is used as close biography 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, as people's physical examination of 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, will make finger close to left-hand door along the opening left-hand door 21 of the track 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 detection finger of proximity transducer 560 for the left-hand door 21.

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, will not enter track when opening the right door 22 as travel mechanism 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 Or 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, is used as left-hand door 21 Proximity transducer 560 human testing scope effective range electromagnetic field 560P and the 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 accidentally and flase drop measures the finger or plug-type door 23 of user.

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 Contact proximity transducer 560 and protection are electric simultaneously in the case of opening left-hand door 21 or right door 22, can prevent ancon for device 560 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 come illustrate left-hand door 21 and right door 22 substrate 553 holding structure example.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.What the limitation proximity transducer 560 of metallic object 591 was produced is used as people 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.The left-hand door 21 as adjacent travel mechanism is configured at as the metallic object 591 of the effective range change mechanism of detection range 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 guard electrode 570 electromagnetic field produce influence.Moreover, the proximity transducer 560 from right door 22 Electromagnetic field and the electromagnetic field of guard electrode 570 will not be produced to the proximity transducer 560 of left-hand door 21 and the electromagnetic field of guard electrode 570 Raw 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.

User makes the proximity transducer 560 of the side of left-hand door 21 shown in finger close to Figure 49 and Figure 50, hence into Figure 49 During with the electromagnetic field 560P of the effective range as human testing scope shown in Figure 50, the proximity transducer of high sensitivity state 560 detect that finger has approached proximity transducer 560.Thus, Figure 54 control unit 556, which is received, represents that finger has approached biography The signal SG of sensor 560.

Then, Figure 54 control unit 556 stops to guard electrode 570 according to the signal SG from the proximity transducer 560 Energization, also, control unit 556 is reduced close to the sensitivity of sensor 560 and is changed to " muting sensitivity " from " high sensitivity ". Also, control unit 556 is illuminated by making LED577 bright lights to proximity switch 560, expresses the position of proximity switch 560, Allow users to the position by visual confirmation proximity switch 560.

Moreover, when finger contacts proximity transducer 560, the proximity transducer 560 of muting sensitivity is played for opening a left side The effect of the soft-touch control (contact-making switch) of door 21, sends finger to Figure 54 control unit 556 and contacts proximity transducer 560 Activation signal SH.Thus, control unit 556 make left-hand door 21 opening door operation effectively, control unit 556 acts enabling drive division 54, Therefore, it is possible to carry out the enabling of left-hand door 21.

In addition, user open right door 22 when action example with above-mentioned opening left-hand door 21 when action example as, therefore, omission Explanation.

So, when user contacts the proximity transducer 560 worked as feeler using finger, control unit 556 Can automatically open up left-hand door 21 or right door 22.

When user only contacts proximity transducer 560, control unit 556 makes proximity transducer 560 (be connect as touch sensor Touch sensor) work, by making the opening door operation " effective " of left-hand door 21, carry out the opening door operation of left-hand door 21.This is for right door 22 is same.

In the case of proximity transducer 560 and the both sides of guard electrode 570 that user touches shown in Figure 51 accidentally, control Portion 556 does not make proximity transducer 560 play a part of 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, in the case of the proximity transducer 560 and the both sides of guard electrode 570 that water droplet is attached to shown in Figure 54 and Figure 51, Control unit 556 makes the opening door operation engineering noise of left-hand door 21 by not making proximity transducer 560 be worked as feeler, Also without the opening door operation of left-hand door 21.Forbidding for above-mentioned opening door operation is same for right door 22.

In addition, in ancon hookup 54 and the guard electrode 570 shown in Figure 51 and the intermediate region portion simultaneously of such as user In the case of point 589 both sides, the opening door operation " effective " of door 21 can be made and the opening door operation of left-hand door 21 is carried out.This is for right door 22 is same.

As described above, the left-hand door 21 and right door 22 of the opposite opened with glass system front panel 21A, 22A have electrostatic respectively Touch type feeler, the electrostatic touch type feeler is used as the close proximity transducer of the finger of detection human body etc. 560.As shown in figure 51, in substrate 553, around the proximity transducer 560 as electrostatic touch electrode, guard electrode 570 are configured to surround proximity transducer 560 to have spaced mode with proximity transducer 560.

The guard electrode 570 be in human body proximity, for change proximity transducer 560 human testing scope it is effective The effective range change mechanism of the detection range of scope.Guard electrode 570 is produced detects the close of human body with proximity transducer 560 When the electromagnetic field of electromagnetic field opposite direction that produces.

Thus, guard electrode 570 proximity transducer 560 is detected human body it is close when the electromagnetic field that produces in upper and lower Limited on to, left and right directions, as shown in Figure 49 and Figure 50, the proximity test electromagnetism that limitation proximity transducer 560 is produced The spreading range of field.Therefore, the electromagnetic field 560P (proximity test scope) that proximity transducer 560 is produced only is limited in close to sensing The positive forward direction of device 560.

Therefore, in the case of the refrigerator of the opposite opened with left-hand door 21 and right door 22, the enabling of such as left-hand door 21 is utilized Close the door, the error detection of proximity transducer 560 of right door 22 can be prevented, closed the door using the enabling of right door 22, left-hand door 21 can be prevented The error detection of proximity transducer 560.

In addition, be not opposite opened refrigerator but in the case of single open-door formula refrigerator, come refrigerator in human body or object Side in the case of, can prevent the careless flase drop of proximity transducer of door from measuring the human body or object.

Thus, even if user is under dim environment, the position in control operation portion 650 can be also recognized, 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 micro, slight bright lights of LED635.Then, in touch controlled key of the user with finger clamshell doors operating portion 651,652 in a non contact fashion 633 carry out touch operation, and in the case that the opening door operation of left-hand door 21 (or right door 22) is set up, 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, touch operation is carried out with the touch controlled key 633 of finger clamshell doors operating portion 651,652 and left-hand door 21 in user In the case that the opening door operation of (or right door 22) is set up, LED635 becomes complete bright light to improve light quantity from glimmer lamp, therefore User can be by the change of the light quantity, i.e. preferably, increases light quantity, visually to confirm the establishment of opening door operation.

Control operation portion 650 for such as user to cooling control content progress change operation 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.

For example, the LED635 bright light opportunity of opening door operation portion 651,652 can be made 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, can also make the LED665 bright lights in control operation portion 650.

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 for directly making 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 be in also not with the close state completely of proximity transducer 607.In the state Under, control unit 656 as the proximity transducer 607 of static switching in order that work 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 switchs (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 the close of finger HT, and therefore, control unit 656 is used as the sensitive of " proximity transducer " using proximity transducer 607 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, therefore, and 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 the opening door operation portion with 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 micro, slight bright light.I.e., micro, slight 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.

For example, it can make the LED635 of opening door operation portion 651 LED665 of the bright light opportunity earlier than 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, control operation portion 650 can be distinguished for user Position and the mode of position of opening door operation portion 651 shown.

Multiple LED577 are equipped with the LED-baseplate 598.

In substrate 553 and the corresponding position of operation sign board 597, left and right slit 574,575 is formed with.The substrate mounting body 500M is accommodated in accommodation space part 585 by the opening portion 586 as the rectangle insert port of 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 are preferred to 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 are 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 is configured 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, it is easy to dismounted using instrument.

Further, since connector component CC1, CC2 position are staggered in the vertical direction, and therefore, the water caused by condensation 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, being 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.It is used 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 configures in back side 553B sides, therefore, as shown in Figure 66, operates 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.Proximity transducer is aided in as the middle region part 589 of the 2nd electrode 560, with the function as proximity transducer.The effective range that the change proximity transducer 560 of guard electrode 570 is detected.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 will not be to close biography The electromagnetic field that the electromagnetic field and guard electrode 570 that sensor 560 is produced are produced brings influence.

As shown in Figure 64 (a) and Figure 65, through hole 560C is formed with the middle position of proximity transducer 560.In the through hole On 560C, such 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 by the linking portion 560A's as the position beyond slit 574,575 Rear side part.Linking portion 560A is explained below.

User presses with finger the behavior of proximity transducer 560 (contact), be 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., for close biography 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, can make finger contact sensitivity highest part.

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, detects human body or object at e.g., from about 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, is provided when to sender electrode 1 sender electrode and 1 receiving electrode During electric current, electromagnetic field is generated, electromagnetic field is received by receiving electrode.Detection of the finger of such as human body close to proximity transducer 560 During region, a part for electromagnetic field is received by absorption 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 of such as long oblong-shaped in longitudinal direction, slit 574th, 575 it is formed in the way of surrounding electrode around proximity transducer 560.I.e., slit 574,575 is to surround close to sensing 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 Multiple light-emitting components worked as lighting device that is, LED577 are formed with across interval.

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 The illumination light that individual LED577 is produced is irradiated in the way of it will not produce influence 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 the way 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 the way of avoiding.By This, linking portion 560A, 560B will not hinder LED577 illumination light.

Electrical connection through hole 560C is formed with the central portion of proximity transducer 560.Like this in proximity transducer 560 Middle body formation 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, being illustrated to the guard electrode 570 shown in Figure 64 and Figure 65.

Guard electrode 570 is formed as in configuration section 572 around proximity transducer 560 and middle region part 589 The frame shape of oblong-shaped.Guard electrode 570 is metallic object, by a pair of short edges electrode part 570A and long a pair side electrode part 570B is constituted.Guard electrode 570 produces the electromagnetic field of the electromagnetic field opposite direction produced with proximity transducer 560.

Thus, as shown in Figure 62 and Figure 63, the extension for the electromagnetic field 560P that proximity transducer 560 is produced is by guard electrode The electromagnetic field of 570 opposite directions produced suppresses.Therefore, suppressed by the electromagnetic field produced by guard electrode 570 close to sensing The extension for the electromagnetic field 560P that device 560 is produced, guard electrode 570 plays the detection model of the effective range of change human testing scope The effect for the effective range change mechanism enclosed.

Guard electrode 570 by way of with constriction such as finger of alteration detection human body it is close when proximity transducer 560 detection range, come the effective range of the detection range that changes 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 The electromagnetic field 560P that proximity transducer 560 is produced is only channeled to the positive forward direction of proximity transducer 560.Equally, right door The electromagnetic field 560P that the proximity transducer 560 of 22 opening door operation portion 552 is produced is only channeled to the front of proximity transducer 560 Forward direction.

Therefore, as shown in Figure 62, the electromagnetic field 560P that proximity transducer 560 is produced is with not in the lateral direction that is, X-direction The mode constriction of extension.

Also, the electromagnetic field 560P that as shown in Figure 63, the proximity transducer 560 of the opening door operation portion 551 of left-hand door 21 is produced 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 The 560 electromagnetic field 560P produced are only channeled to the positive forward direction of proximity transducer 560.Therefore, in Figure 63, close to biography Sensor 560 produce electromagnetic field 560P by not vertically that is, Z-direction extension in the way 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 (above and below, the scope of left and right extension) different scope.

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 During for electromagnetic field 560P shown in Figure 62 and Figure 63 of the detection zone of proximity transducer 560, 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 is being received from the proximity transducer 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 effective, 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 is 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 passes through " high sensitivity " by 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, is used as the function " effective " of " proximity transducer ".Therefore, control unit 556 does not make proximity transducer 560 work as " feeler ", therefore, and 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, making 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 is switched 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, by contacting close 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, thus the configuration protection electrode 570 around proximity transducer 560, is used as close biography 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, as the human body of 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 open left-hand door 21 along the track shown in arrow 21K and make finger close to a left side 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, 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 detection finger of proximity transducer 560 for the left-hand door 21 that closed.

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 careless flase drop of proximity transducer 560 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, along the direction of arrow pull out as travel mechanism push-pull door 23 when, be used 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 The careless flase drop of sensor 560 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 long a pair side electrode part 570B is constituted.For example, when attachment of moisture is in before the left-hand door 21 shown in Figure 61 Panel 21A, the moisture is attached to the front panel 21A of the position of guard electrode 570 always, so that guard electrode 570 is because of moisture 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 is 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, enabling drive division of the control unit 556 caused by by making proximity transducer 560 shown in Figure 67 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 When family while finger contact protection electrode 570 with proximity transducer 560 is contacted, 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, 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, during the control operation portion 650 on the surface for wiping the front panel 21A of left-hand door 21 with wet rag in such as user, The water is dripped 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 and the electrode gap of longitudinal direction of the horizontal electrode gap of guard electrode 570 shown in Figure 65 It is spaced RF bigger than the finger HT of human body width MF.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 close to close biography 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 size of guard electrode 570 will not also be touched by encountering the ancon of the bending of human body.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.By 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 approaches in the case of opening left-hand door 21 or right door 22, can also prevent ancon while contacting 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 come illustrate left-hand door 21 and right door 22 substrate 553 holding structure example.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 substrate 553 holding structure left-hand door 21 medial extremity face 21T (the medial extremity face 22T of right door 22) construction stand 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 the way of being inserted into from opening portion 586 in accommodation space part 585.

Wherein, substrate mounting body 500M is being inserted into accommodation space part 585 come in the case of storing 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.The conduct that the limitation proximity transducer 560 of metallic object 591 is produced The electromagnetic field of the effective range of human testing scope, is the change of the effective range for the detection range for changing proximity transducer 560 Mechanism.The left-hand door as adjacent travel mechanism is configured at as the metallic object 591 of the effective range change mechanism of detection range 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 and the electromagnetic field of guard electrode 570 of left-hand door 21 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 is received, 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 be 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 into proximity transducer 560 is sent to figure 67 control unit 556.Thus, control unit 556 make left-hand door 21 opening door operation effectively, control unit 556 make enabling drive division 54 move Make, therefore, it is possible to make left-hand door 21 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 with 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 because water droplet adheres to and causes the proximity transducer 560 shown in Figure 64 and the both sides of guard electrode 570 inspection 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, shown in Figure 64 proximity transducer 560 detection user finger HT close " proximity test pattern " and " the electrostatic touch mode " that works as feeler of the finger HT of the detection user of proximity transducer 560 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.

Include as the situation of switch mode：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 sensor 560 as the electrostatic touch sensor of " electrostatic touch mode ".

On the contrary, from " electrostatic touch mode " switch to " proximity test pattern " when, finger HT depart from proximity transducer 560, When passing through stipulated time, such as 10 seconds from " electrostatic touch mode ", or reset carried out by closing the door etc. from opening the door, 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 the door 21 on the left of opening, progress is used 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 Portion 556 as the proximity transducer 560 of static switching as " proximity transducer " in order that work, control unit 556 makes to approach Sensor 560 is opened and is set as " height " to improve sensitivity by the sensitivity of proximity transducer 560, 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, is used as the function " effective " of " 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, therefore, and control unit 556 makes proximity transducer 560 be opening, will be close to sensing The sensitivity as " proximity transducer " of device 560 switches to " low " to reduce sensitivity from " height ", weakens proximity transducer Function, disconnects middle region part 589.

Therefore, control unit 556 makes proximity transducer 560 be worked as feeler, therefore, and 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 is shown as " opening ", as both LED lighting lamp states, for example, carries out micro, slight bright light.I.e., shown in Figure 58 The micro, slight bright lights of LED665, thus, are illuminated and light to control operation portion 650, the LED577 shown in Figure 52 is micro, slight from behind Bright light, the proximity transducer 560 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 worked as feeler, it 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 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.For example, 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 the LED665 in control operation portion 650 LED577 of the bright light opportunity earlier than proximity transducer 560 bright light opportunity.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 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 shown as the LED of proximity transducer 560 bright light State, the change illumination mode of control unit 556, common bright light is become from micro, slight 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 worked as feeler and lighted in the way 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, thus, approached with the complete bright light based on bigger light quantity progress 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, it is possible to 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 micro, slight bright light and improves light quantity, therefore, and user can be by the increasing of bright light amount Plus and visually confirm that opening door operation has been set up.Also, user can more reliably recognize 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 is close in the case of proximity transducer 560, in finger HT contacts 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 is acted, thus, carries out the enabling control of corresponding left-hand door 21.Thus, left-hand door 21 can be automatically opened up.Then, Control unit 556 makes the function engineering noise of the proximity transducer 560 worked as feeler.

Also, control unit 556 makes the bright light in control operation portion 650 show at the slit 574,575 with proximity transducer 560 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 engineering noise is become from " effective ".

As described above, as the opening action for the left-hand door 21 that reference picture 74 illustrates, 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 detection finger contact principle.Figure 75 is to represent close The circuit diagram of the principle of the detection finger of sensor 560 HT contact.

Contact detection circuit 888 shown in Figure 75 has：It is used as the proximity transducer 560 of feeler (Cx), adjustment 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 accumulate electric charge with continuation untill capacitor (Cmod) 889 turns into current potential is adjusted, and 895 pairs of counter is until adjusting electric capacity The number of times of pulse untill the accumulation regulation electric charge of device (Cmod) 889 is counted.

When finger HT contacts the proximity transducer 560 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 completes 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 is counted) 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, to finger HT contact as feeler (Cx) proximity transducer 560 when sensitivity change side Method is illustrated.

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 is well over threshold value, sensitivity increase.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 with finger tip contacts, being also capable of detecting when to come, it is possible to increase sensitivity.In addition, although also can by reducing threshold value Sensitivity is improved, still, due to there is the problem of noise can be also detected, 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 ground connection 569 are located 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 the action that finger HT carries out electrostatic touch to proximity transducer 560, approaching during finger HT contacts is detected The electrostatic capacitance CX of sensor 560 change.In addition, being detected in detection finger HT close in the action of proximity transducer 560 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, changes 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 that is worked as the 1st electrode that is, feeler and it is used as the 2nd electricity 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, makes proximity transducer 560 carry out internal connection with middle region part 589, or can release internal connection.

(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 Points 589 connection.Thus, only proximity transducer 560 is used 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 the situation from electrostatic touch mode to 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 can be connected with middle region part 589.

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 It is used as the modification of 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 the way 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, the adjacent door 21 (or door 22) of travel mechanism, the water bottle of the door compartment for the rear side for being positioned over door are used as 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, for the change of the proximity test effective range that carries out proximity transducer 560, it is used as the effective model of proximity test The change mechanism enclosed, 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) It is used as the guard electrode 570 of 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, does not form electric field from proximity transducer 560 and middle region part 589 to grounding pattern 573.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, (elimination) is disappeared 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 into 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.Even if in addition, setting the metallic object 591 shown in Figure 53, can also make electric field have 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.

Next, illustrating the use example of above-mentioned refrigerator 1.

In the use example of following explanation, illustrate to make bimanual finger hold article in user, such as plate, pot and In the state of both hands take, it is impossible to using finger by contacting come the proximity transducer 711~714 shown in operation diagram 69, carry out Such as situation of the door opening action of left-hand door 21 (or right door 22).

In this case, the position of the human body of the user of proximity transducer 711~714 can be operated in a non contact fashion, It is palm (metacarpus, the back of the hand), the sidepiece of hand or ancon etc..

As described above, making a reservation for proximity transducer 711~714 using palm, the sidepiece of hand or ancon etc. in user Particular order when detecting them, control unit 756 can drive the enabling drive division 54 of such as left-hand door 21 to open left-hand door 21, Or control unit 756 can drive the enabling drive division 55 of right door 22 to open right door 22.

Figure 72 shows user using the action (posture) of palm, the sidepiece of hand or ancon etc. to proximity transducer 711 ~714 carry out the example of Proximity operation with predetermined particular order.

The particular order refer to make the palm of user, the sidepiece of hand or ancon into proximity transducer 711~714 extremely Few more than 2 proximity transducer, close to mobile path, is predetermined.

Particular order shown in Figure 72 (a) is along arrow institute to the right by the palm of user, the sidepiece of hand or ancon The 1st direction DD1 movements shown, 2 proximity transducers 711,712 detect human body (palm, the sidepiece or ancon of hand) successively, And by being moved along with the 2nd direction (opposition direction) DD2 shown in the arrow to the left different from the 1st direction DD1,2 Proximity transducer 712,711 is detected obtained from human body (palm, the sidepiece or ancon of hand) successively.

In this case, the 1st direction DD1 and the 2nd direction DD2 constitutes the 1st specific direction F1, the 1st specific direction F1's Particular order is：The function of door opening action by the progress left-hand door 21 of enabling drive division 54 is indicated such as control unit 756.

Other particular order shown in Figure 72 (b) is：By the palm of user, the sidepiece of hand or ancon along with to The 1st direction DD1 movements shown in right arrow, 2 proximity transducers 711,712 detect human body (palm, the sidepiece of hand successively Or ancon), and by being moved along with the 3rd direction DD3 shown in the downward arrow different from the 1st direction DD1,2 Proximity transducer 712,713 is detected obtained from human body (palm, the sidepiece or ancon of hand) successively.

In this case, the 1st direction DD1 and the 3rd direction DD3 constitutes the 2nd specific direction F2, the 2nd specific direction F2's So-called " air cooling jelly " function that particular order is indicated control unit 756, that is, indicate：The conduct for allowing hand over such as refrigerator 1 is received Receive the function of drastically being freezed in the switching chamber 14 of design temperature in the refrigerator for example shown in Figure 69 of room.It is somebody's turn to do " air cooling jelly " Function is cellular damage of gas ground when being frozen -1 DEG C~-5 DEG C of temperature band by food water come freezing-inhibiting, is protected Hold the function of well tasting.

As described above, by user with the action (posture) of palm, the sidepiece of hand or ancon etc. to proximity transducer 711 At least two proximity transducer in~714 carries out Proximity operation with predetermined particular order, as predetermined function, can beat Create a precedent such as left-hand door 21, or the right door 22 of opening.

Thus, even if proximity transducer 711~714 is configured at into left-hand door 21 or right door 22, it can also prevent in user Simply before refrigerator 1 by when, left-hand door 21 or right door 22 are opened.

In addition, Figure 73 is the example for representing to carry out proximity transducer with other predetermined particular orders Proximity operation Figure.

As shown in Figure 73, in the state of user holds plate, pot etc. using both hands finger and both hands take, it is impossible to use When the finger of both hands carries out Proximity operation to proximity transducer 711~714, by using the side of palm (metacarpus, the back of the hand), hand Portion, ancon etc. make proximity transducer 711~714 be detected in a non contact fashion according to predetermined particular order, also can be right The indicating predetermined any function of control unit 756.

Make palm (metacarpus, the back of the hand), the sidepiece of hand, ancon action and the direction that moves can upper and lower in any combination To, left and right directions, it is oblique in the direction of 2 or more than 3 use.

For example, in Figure 73 (a), showing the 1st direction (right) DD1 and the 4th direction (obliquely downward) DD4 combination, scheme In 73 (b), the 5th direction (lower section) DD5 and the 6th direction (top) DD6 combination are shown.

In Figure 73 (c), the 3rd direction (lower section) DD3 and the 7th direction (top) DD7 combination are shown, in Figure 73 (d) In, show the 8th direction (right) DD8 and the 9th direction (left) DD9 combination.

By the combination of the posture of these multiple directions, control unit 756 can play opening such as left-hand door 21 or right door The various functions of 22 grades.

In the example in the figures, operation detection part 701 is made up of 4 proximity transducers 711,712,713,714.But, Be not limited to this, operation detection part 701 can also by 2 proximity transducers, 3 proximity transducers, more than 5 close to sensing Device is constituted.These proximity transducers can two-dimentional (in plane) configuration on door.

In above-mentioned refrigerator 1, left-hand door 21 and right door 22 with opposite opened, in the front-surface side of left-hand door 21 and right door 22 It is configured with front panel 21A, 22A as glass plate.But, however it is not limited to this, the front-surface side of left-hand door 21 and right door 22 also may be used Be not glass plate but the metallic plate such as steel plate.In addition, being used as refrigerator, it is possible to have 1 fan door of single open-type.
