Here, referring to the flow chart for the left-hand door 21 and Figure 33 in the case where right door 22 for automatically opening refrigerating chamber, specifically Illustrate the case where user is automatically turned on left-hand door 21 and right door 22 by voice.

In Figure 33, in step s 11, such as keyboard of user's preparatory operative association input registration unit 305, touching Template etc. inputs such as " milk ", " egg ", " butter " with the storage shelf of 21 side of left-hand door and is registered, in association to the right side The input of storage shelf such as " fruit juice ", " mustard ", " bean curd " of 22 sides of door are registered.Control unit shown in Figure 32 as a result, 56 make storage unit 300 shown in Figure 32 and the storage shelf of 21 side of left-hand door that (storage) such as " milk ", " chicken be arranged in association (storage) such as " fruit juice ", " mustard ", " beans is arranged for the storage shelf of right 22 side of door in step s 12 in egg ", " butter " It is rotten ".

In the step S13 of Figure 33, by such as human body detection sensor HS or illuminance transducer LS etc. detect using 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 illuminance signal to control unit 56.Therefore, in control unit 56, control unit 56 is caused by detection signal or illuminance signal The triggering that starts of speech identifying function, i.e., generate the opportunity for playing speech identifying function in control unit 56, control as a result, The speech identifying function in portion 56 is started to work.

In this way, the triggering that the speech identifying function starts is: detecting to make close to refrigerator in human body detection sensor HS In the case where user, when sending detection signal to control unit 56 from human body detection sensor HS, or in illuminance transducer LS inspection In the case where 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 the step S14 of Figure 33, user with voice say " milk ", " egg ", in " butter " at least At 1, voice recognition sensor NS1, NS2 shown in Figure 32 receive the voice and send voice signal to control unit 56, therefore Control unit 56 identifies voice.As a result, in step S15, control unit 56 is directed to and is at least accommodated with " milk ", " egg ", " butter " In at least one Figure 32 shown in the enabling driving portion 54 of left-hand door 21 export enabling driving instruction, keep enabling driving portion 54 dynamic Make.Therefore, in step s 16, the storage shelf of left-hand door 21 can be automatically turned under the movement of enabling driving portion 54.

Equally, in step S14, when user says " fruit juice ", " mustard ", at least one in " bean curd " with voice, figure Voice recognition sensor NS1, NS2 shown in 32 receive the voice, send voice signal to control unit 56, therefore control unit 56 is known Other voice.As a result, in step S17, control unit 56 to be accommodated with " fruit juice ", " mustard ", at least one in " bean curd " right door 22 enabling driving portion 55 exports enabling driving instruction, acts enabling driving portion 55.Therefore, in step S18, right door 22 Storage shelf can be automatically turned under the movement of enabling driving portion 55.

In storage unit 300, such as registers in association in advance and be put into the storage of 21 side of left-hand door of " milk " and put Frame if saying " milk ", can be automatically turned on a left side even not knowing the people at the position being put into the refrigerator of " milk " Door 21.Thus, it is not known that the people at the position being put into the refrigerator of " milk " will not mistakenly open the right door for not being put into " milk " 22.Therefore, the either on or off number of door is reduced, and improves energy-saving effect.

In addition, for example being said " water storage ", being put by user in the case where being configured with the water tank of ice making in refrigerator Set the door of water tank side, such as left-hand door 21 will be opened, user can receive water tank in the state of holding water tank It is contained in the regulation reception position of the water tank in refrigerator.Even if as a result, user's both hands hold water tank and what both hands took In the case of, it can be also automatically turned on without using handle 61 shown in Figure 29 in order to store water tank and to be opened for example left Door 21.

In addition, can also be driven by being respectively set to open the door for door 23,24,25,26 plug-type shown in Figure 29 Dynamic portion, carries out automatic door opening using voice in the same manner as left-hand door 21 and right door 22.

In this way, catching handle with user to manually turn on left-hand door 21, right door 22, plug-type door 23,24,25,26 Manual operation it is different, door can be automatically turned on, therefore inferior in the situation that such as user's both hands hold food etc., very It is convenient.

It, can be by the door that keeps these different in addition, in the case where the open voice of identification is sent as an envoy to different at the same time door Opening opportunity be staggered it is open etc. to carry out, prevent door from conflicting with user's generation.

In addition, providing the triggering started for speech recognition as to control unit 56 in step S13 shown in Figure 33 Example is obtained from the language (word) issued as voice recognition sensor NSl, NS2 identification user from speech recognition The voice signal of sensor NSl, NS2.As the predetermined language (word) that user issues, such as " sesame can be used Numb quick operating valve " etc..I.e., the preference of the triggering started for speech recognition is provided as to the control unit 56, it is desirable to be for example " open sesame ", the word for being not in usual session as " sesame quick operating valve " in turn.

I.e., in the case where providing the example of the triggering started for speech recognition to control unit 56 is the sound of people, it is It prevents from may result in using the word occurred in common session content control unit 56 and starts to carry out speech recognition movement The problem of, it is preferable to use the word for being not in common session.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 generate with refrigerator miscellaneous Sound, passes through dust catcher or room used in warning tones of door when open, the opening and closing sound of door, room at the sound such as compressor Between middle broadcasting music etc. the different sound of sound.In addition, when the sound that will be identified is set as the sound of non-voice, such as Fruit is set to identify the sound that repeatedly (such as 2 times) clap hands, then because different from the sound that refrigerator generates, and is not in miss Switch.

Next, illustrating the voice recognition sensor NS2 for being configured at the lower part of right door 22 shown in Figure 30 referring to Figure 34 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 lower part 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 The inner surface 135M of 121M and offside door cover 135.The storage member 105 is the portion for being configured to the incorporating section of storage substrate 110 Part.Hole portion 154 is set to the lower part of the offside door cover 135 of for example right door 22.The voice etc. that user generates passes through hole portion 154 Reach voice recognition sensor NS2.The hole portion 154 can be to be made of single hole, is also possible to be made of multiple holes.By This, voice recognition sensor NS2 can be configured in the lower part for being built in right door 22, and can be reliable by hole portion 154 Voice etc. outside ground pickup.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 aperture is formed covering.

As shown in figure 32, control unit 56 is connected to illumination region 330, sound generating unit 340, voice generating unit 350.Illumination region 330, 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 where opening door, informing mechanism that the goalkeeper is opened is informed to user in order to alert.

Illumination region 330 is such as LED illumination region, 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 issues the instruction for opening such as left-hand door 21 or right door 22, and control unit 56 can make illumination region 330 shown in Figure 32 It is shone with such as " redness of the skin or complexion ", so that sound generating unit 340 is generated alarm tone or make voice generating unit 350 with voice to making User informs the warning such as " goalkeeper is opened " content.Thereby, it is possible to be informed with light, sound, at least one of voice user Goalkeeper is opened, and therefore, can 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 detection When to user close to refrigerator, detection signal is issued to control unit 56 and notifies to detect people.In this way, control unit 56 is detecting When 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 inquires " opening door? " such inquiry content.It in this case, should if user answers such as " YES " " YES " is identified by voice recognition sensor NS1, NS2, and voice signal is notified to control unit 56.Control unit 56 is logical as a result, It crosses to the enabling driving portion 55 of for example right door 22 and exports enabling driving instruction, right door 22 can be opened.Equally, control unit 56 passes through Enabling driving instruction is exported to the enabling driving portion 54 of such as left-hand door 21, left-hand door 21 can be opened.

In addition, the left-hand door 21 and right door 22 can make respective opening speed different.Left-hand door 21 and right door 22 are in drive of opening the door Under the driving in dynamic portion 54,55, usually opening speed is set to slowly slack-off, open door will not sharply.

As shown in figure 35, height measurement sensor 410 is connected 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 such as height measurement sensor 410 Can discriminating measurement go out user height values reach the left-hand door 21 of upper layer side and the value of right door 22 or not up to value i.e. It can.Control unit 56 can make the left-hand door of upper layer side based on the height values of the user of the measurement of height measurement sensor 410 as a result, 21 is different from the opening speed of right door 22.

Such as the height values of the user measured in height measurement sensor 410 are 21 and of left-hand door for reaching upper layer side In the case where the value of right door 22, control unit 56 keeps the movement of enabling driving portion 54,55 further slack-off, enabling driving portion 54,55 The speed for making left-hand door 21 and the right door 22 of upper layer side further slow down than respective normally open speed is opened.

Thus, it is possible to which left-hand door 21 and right door 22 is avoided to bump against head or the body of user.It is 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 The left-hand door 21 and right door 22 that dynamic portion 54,55 makes upper layer side are respectively with common opening speed opening.

The control unit 56 shown in Figure 32 or Figure 35 is informed user using voice generating unit 350 and " will for example be opened In the case where the such warning content of right door ", when the user wants to confirm the warning content again, can as follows into Row.When user says " again " or content is urged in " repetition " such repetition, voice recognition sensor NS1, NS2 will " again " or " repetition " such voice signal for repeating urgency content is sent to control unit 56.Control unit 56 is by coming from The voice signal of voice recognition sensor NS1, NS2, at least being informed again user using voice generating unit 350 " will beat Open right door " such alert content.Even if user misses the warning content of refrigerator side sending as a result, also can simply again Secondary confirmation.

In addition, opening the right door 22 of the refrigerating chamber on upper layer when to observing in refrigerator in user, control unit 56 is not Receive the operation for example automatically opened as other left-hand door 21.As a result, user open right door 22 and in refrigerator into Row observation, and user mutters to oneself when saying such as " milk must also take out ", can prevent the left-hand door 21 for being placed with " milk " side It mistakenly automatically opens, 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 layer is opened in user when to observing in refrigerator, is muttered to oneself and is said " vegetable Dish must also take out " when, can prevent the door of the vegetable compartment for being placed with " vegetables " mistakenly automatic spring and bump against under user Abdomen or knee etc..

In addition, also can be set to make it when some door is opened other than making to receive in vain as described above The breakaway speed of his door is slower than common speed.

In addition, speech recognition becomes to be known well when refrigerator issues noise (compressor sound, buzzer sound) In other situation, " please say it again " etc. can also be issued from loudspeaker to the instruction voice of user.

As shown in figure 35, proximity sensor 400 is connected on control unit 56.The proximity sensor 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 soft-touch control opening door operation portion 51, 52, control operation portion 50 is luminous using carrying out such as LED light.Even if the position for placing refrigerator as a result, is dark place, user Can visual confirmation opening door operation portion 51,52, control the position of operation portion 50.

It is configured on the configuration section 572 of the side surface 553A shown in Figure 51 (a): as the 1st electrode close to sensing Device 560, as the guard electrode 570 of the 3rd electrode, as the middle region part 589 of the 2nd electrode.Middle region part 589 is set It is placed between proximity sensor 560 and guard electrode 570.Proximity sensor 560, guard electrode 570 and middle region part 589 It is metal electrode, still, is electrically insulated from each other.Middle region part 589 as the 2nd electrode assists proximity sensor 560, tool There is the function as proximity sensor.The detection effective range of the change proximity sensor 560 of guard electrode 570.

In addition, as shown in Figure 51 (b), the back side 553B corresponding to the configuration section 572 of substrate 553 is configured with conduct The netted grounding pattern 573 of 4th electrode.The grounding pattern 573 pass the noise from refrigerator main body will not to close as a result, The electromagnetic field that the electromagnetic field and guard electrode 570 that sensor 560 generates generate has an impact.

As shown in Figure 51 (a) and Figure 52, it is formed with through-hole 560C in the central location of proximity sensor 560, still, at this On through-hole 560C, as shown in Figure 51 (b), it is connected with wire pattern 560H.User presses with finger proximity sensor 560 (contact) Behavior, usually carried out using the center of proximity sensor 560 as target, therefore through-hole 560C is formed in proximity sensor 560 center position.

The reasons why through-hole 560C is formed in the position of proximity sensor 560 substantially hit exactly like this is as follows.I.e., it is connecing In nearly sensor 560, the middle section of through-hole 560C is formed compared with other regions, switchs sensitivity highest.Accordingly, pass through The finger pressing of user has the center close to switch 560 of through-hole 560C, can make finger contact sensitivity highest place.

Proximity sensor 560 shown in Figure 51 and Figure 52 is that electrostatic touches (contact) with electrode, and is: for Figure 49 with Human body or object are detected in front (front surface) direction of left-hand door 21 and right door 22 shown in Figure 50 at for example, about 100mm Close electrostatic capacitance testing agency.The proximity sensor 560 is in a part of the human body of user, specifically such as finger When close, the close of the finger is detected.Although proximity sensor 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 of 1 sender electrode and 1 receiving electrode, is provided when to sender electrode When electric current, electromagnetic field is generated, electromagnetic field is received electrode reception.Such as the finger of human body is close to the detection of proximity sensor 560 When region, the energy that a part of electromagnetic field is absorbed and is received electrode reception, therefore is detected is reduced, and is approached as a result, Sensor 560 is capable of detecting when the close of finger.

For self capacitive way, the electrode (proximity sensor 560) with stray capacitance needs 1.Electrode (connects Nearly sensor 560) stray capacitance by being located at the electrode (proximity sensor 560) and the surrounding electric conductor (hand of human body Refer to) between effect of parasitic capacitance.When the finger of human body is close to proximity sensor 560, influenced by parasitic capacitance, stray capacitance Value increase, by measuring the increased stray capacitance, proximity sensor 560 is capable of detecting when the close of finger.

As shown in Figure 51 and Figure 52, proximity sensor 560 is created as the switch for the oblong-shaped for example longitudinally grown, slit 574,575 are formed as surrounding electrode around proximity sensor 560.As shown in figure 52, from the back side on the slit 574,575 Be covered with substrate 598, the LED577 to work as lighting device be arranged at intervals have it is 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 sensor 560 is linked by linking portion 560A and configuration section 572, is connect The other end of nearly sensor 560 is linked by linking portion 560B and configuration section 572.In proximity sensor 560 Centre portion is formed with the through-hole 560C of electrical connection.Through-hole 560C is formed in the center portion of proximity sensor 560 like this, such as As illustrating, the region part of the proximity sensor 560 of through-hole 560C is provided with compared with other region parts, detection spirit Sensitivity is high.Since the finger of user approaches and the region part that contacts is the center portion of proximity sensor 560, it will lead to Hole 560C is disposed proximate to the center portion of sensor 560.The slit that proximity sensor 560 passes through the configuration section in substrate 574, in 575 region 572a, electrode is formed in dashed region, is shaped generally as rectangle.In addition, slit 574,575 is not Entire proximity sensor 560 is surrounded, and is created as U-shaped.This results in following compositions: around formation and slit The bridge 572ab of periphery 572b connection, 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 sensor 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 section 570A It is constituted with a pair of of long side electrode section 570B.Guard electrode 570 generates the electromagnetic field opposite direction generated with proximity sensor 560 Electromagnetic field.

As a result, as shown in Figure 49 and Figure 50, the electromagnetic field 560P that proximity sensor 560 generates is generated in guard electrode 570 Opposite direction electromagnetic field under the action of, extension be suppressed.Therefore, pressed down by the electromagnetic field generated by guard electrode 570 The extension for the electromagnetic field 560P that proximity sensor 560 processed generates, guard electrode 570 play the effective range change machine of detection range The effect of structure, the effective range of the detection range of the effective range change mechanism change human body of the detection range.

Guard electrode 570 changed in a manner of constriction make such as finger for detecting 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 sensor 560.Specifically, guard electrode 570 The effective range of the detection range of proximity sensor 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 generates of proximity sensor 560 be directed only to the positive forward direction of proximity sensor 560.Equally, right door The electromagnetic field 560P that the proximity sensor 560 of 22 opening door operation portion 552 generates be directed only to proximity sensor 560 just in face of Fang Fangxiang.

Therefore, as shown in figure 49, the electromagnetic field 560P that proximity sensor 560 generates is narrowed down, so that will not be as a left side It is extended in the X-direction of right direction.

Moreover, as shown in figure 50, the electromagnetic field 560P that the proximity sensor 560 of the opening door operation portion 551 of left-hand door 21 generates It is directed only to the positive forward direction of proximity sensor 560.Equally, the proximity sensor 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 sensor 560.Therefore, in Figure 50, proximity sensor The 560 electromagnetic field 560P generated are narrowed down, so that will not extend in the Z-direction as up and down direction.

I.e., the electromagnetic field 560P of proximity sensor 560 shown in Figure 49 and Figure 50 shows the effective of the detection range of human body Range, the effective range of the detection range of the human body be equivalent to and proximity sensor 560 front different directions range (on Under, the range of left and right extension) different range.I.e., the effective range of the detection range of human body is at least by proximity sensor 560 The range 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 in addition to the range with front different directions at least part (to up and down, left and right, after At least part of the range just extended etc.) except range.

Figure 54 be indicate control unit 556, opening door operation portion 551,552, as enabling driving portion 54,55 of door opener etc. Electrical connection block diagram.

As shown in figure 54, control unit 556 is electrically connected to the proximity sensor 560 and protection electricity of opening door operation portion 551,552 Pole 570, enabling driving portion 54,55 and multiple LED577 as lighting device.

Control unit 556 makes proximity sensor 560 keep " high sensitivity " state.Finger is entered as proximity sensor When in electromagnetic field 560P shown in Figure 49 and Figure 50 of 560 detection zone, the control unit 556 of Figure 54 is from proximity sensor 560 Signal SG of the reception finger close to proximity sensor 560.

Then, when the control unit 556 of Figure 54 receives the signal SG from the proximity sensor 560, it is judged as that finger connects Close proximity sensor 560, and stop the energization to guard electrode 570, while by the sensitivity of proximity sensor 560 from " high Sensitivity " is changed to " muting sensitivity " to reduce sensitivity.Also, control unit 556 is being received from the proximity sensor 560 Signal SG when, control unit 556 makes LED577 bright light, to close to illuminating around switch 560, is made as a result, by illuminating It floats close to the position of switch 560, allows users to the position by visual confirmation close to switch 560.

In addition, the effect as LED577 bright light, shows due to carrying out bright light by LED577, user is able to confirm that Operating position does not need the printing for implementing to indicate the operating position of operation portion to the front panel 21A (or 22A) as glass plate Deng.

In addition, when being transferred to contact proximity sensor 560 close to the state of proximity sensor 560 from finger, close to sensing Device 560 works as contact-making switch, and proximity sensor 560 sends finger to control unit 556 and contacts proximity sensor 560 Activation signal SH.Control unit 556 makes proximity sensor 560 work as contact sensor as a result, makes opening for such as left-hand door 21 Door operation is effective, and control unit 56 can make the movement of enabling driving portion 54 actually to carry out the opening door operation of left-hand door 21.Aforesaid operations It sequentially, is also same for right door 22.

User can contact while visual confirmation by the illumination of LED577 and be configured at left-hand door 21 or right door as a result, The position close to switch 560 on the inside of 22 glass surface, 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 sensor 560 from finger when close It is switched to " muting sensitivity ", proximity sensor 560 is made to play the role of contact sensor.When finger is close to proximity sensor 560, Control unit 556 makes static switching 560 as " proximity sensor " and works, and therefore, control unit 556 is by by proximity sensor 560 sensitivity is set as "high", and the function as " proximity sensor " is " effective ".Therefore, control unit 556 does not make to approach Sensor 560 works as " contact sensor ", therefore proximity sensor 560 makes the conduct of opening door operation portion 551,552 Originally opening (opening door operation) engineering noise of the left-hand door 21, right door 22 of function.

As described above, making the finger of user close to proximity sensor 560, finger is entered as proximity sensor 560 When the electromagnetic field 560P of the effective range of human testing range, proximity sensor 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 sensor 560, control unit 556 will be passed as close The sensitivity of sensor 560 is set as " low " from "high" switching.Also, control unit 556 make the bright light of proximity sensor 560 show from Closed state becomes open state, and the position of proximity sensor 560 can be expressed using LED577.Therefore, user can be on one side The position of visual confirmation proximity sensor 560 reliably contacts proximity sensor 560 with finger on one side.Control unit 556 makes to approach Sensor 560 plays the role of " contact sensor " as original function, therefore, by contacting proximity sensor with 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, guard electrode 570 is configured around proximity sensor 560, is passed as a result, as close The electromagnetic field 560P of the effective range of the human testing range 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 for example, about 100mm manpower, finger it is close.At this point, the human body as proximity sensor 560 is examined Survey range effective range electromagnetic field 560P because configuration guard electrode 570 and limited so that in above-below direction and left and right It is not extended on direction.

As shown in figure 49, for effective model of the human testing range of left and right directions (X-direction) limitation proximity sensor 560 The extension enclosed will make finger close to left-hand door along the opening left-hand door 21 of track shown in arrow 21M as a result, as shown in figure 49 When 21 proximity sensor 560, the proximity sensor 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 sensor 560 when, can not allow closing Left-hand door 21 proximity sensor 560 detect finger.

Therefore, the electromagnetic field 560P as the effective range of the human testing range of the proximity sensor 560 of right door 22, no It can enter in track when opening the left-hand door 21 as mobile mechanism.Equally, the people as the proximity sensor 560 of left-hand door 21 The electromagnetic field 560P of the effective range of body detection range will not enter track when opening the right door 22 as mobile mechanism It is interior.

Opening left-hand door 21 or when right door 22 as a result, can prevent from not opening but the right door 22 of side that is closed Either the proximity sensor 560 of left-hand door 21 accidentally and erroneous detection 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 for limiting proximity sensor 560 for up and down direction (Z-direction) The extension for the effective range enclosed, when the plug-type door 23 of mobile mechanism will be used as to pull out in the direction of the arrow, as left-hand door 21 Proximity sensor 560 human testing range effective range electromagnetic field 560P and proximity sensor as right door 22 The electromagnetic field 560P of the effective range of 560 human testing range will not be entered in track when opening plug-type door 23.

As a result, when opening plug-type door 23, the proximity sensor 560 of left-hand door 21 and approaching for right door 22 can be prevented Sensor 560 accidentally and erroneous detection 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, contact in user's such as ancon rather than finger close to sensing Device 560 in the case where opening left-hand door 21 or right door 22, can prevent ancon while contact proximity sensor 560 and protection electricity 570 both sides of pole.User also can open left-hand door 21 or right door 22 with finger with ancon as a result,.

Next, illustrating the holding structure example of the substrate 553 of left-hand door 21 and right door 22 referring to Figure 55.Figure 55 is to indicate left The figure of the holding structure example of the substrate 553 of door 21 and right door 22.Figure 55 (a) is the main view of left-hand door 21 and right door 22, Figure 55 (b) It is to show the inner end face 21T (the inner end face 22T of right door 22) of the left-hand door 21 for the holding structure for indicating substrate 553 The perspective view of construction.Figure 55 (c) is the figure for indicating the example of cover 590.

As shown in Figure 55 (a), in the state of closing left-hand door 21 and right door 22, the inner end face 21T of left-hand door 21 and the right side The inner end face 22T of door 22 is closed in opposite directions.The rectangular opening portion 586 of storage space component 585 is located at each inner end Facial 21T, the storage space component 585 of substrate mounting body 500M are located at the inside of left-hand door 21 and right door 22.Substrate mounting body 500M is inserted into storage space component 585 from opening portion 586 and is contained.

It is closed after having stored substrate mounting body 500M using cover 590 opening portion 586.In the cover 590 Internal surface configurations have metallic object 591 as aluminium foil strip, iron plate.What the limitation proximity sensor 560 of metallic object 591 generated is used as people The electromagnetic field of the effective range of body detection range, and be the change for changing the effective range of detection range of proximity sensor 560 Mechanism.The metallic object 591 of effective range change mechanism as detection range is configured at the left-hand door 21 as adjacent mobile mechanism Between right door 22.

By the way that metallic object 591 is configured at 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 sensor 560 of left-hand door 21 and the electromagnetic field of guard electrode 570 will not be to right doors 22 Proximity sensor 560 and the electromagnetic field of guard electrode 570 have an impact.Moreover, the proximity sensor 560 from right door 22 Electromagnetic field and the electromagnetic field of guard electrode 570 will not the electromagnetic field of the proximity sensor 560 to left-hand door 21 and guard electrode 570 produce It is raw to influence.

Next, the action example in the case where illustrating user's opening such as left-hand door 21 referring to Figure 48~Figure 50 and Figure 54.

User makes finger close to the proximity sensor 560 of 21 side of left-hand door shown in Figure 49 and Figure 50, hence into arriving Figure 49 When with electromagnetic field 560P shown in Figure 50 as the effective range of human testing range, the proximity sensor of highly sensitive state 560 detect that finger has approached proximity sensor 560.The control unit 556 of Figure 54, which receives, as a result, indicates that finger has approached biography The signal SG of sensor 560.

Then, the control unit 556 of Figure 54 stops according to the signal SG from the proximity sensor 560 to guard electrode 570 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 and making LED577 bright light to close to switch 560, expresses the position for approaching switch 560, Allow users to the position by visual confirmation close to switch 560.

Moreover, the proximity sensor 560 of muting sensitivity, which plays, is used to open a left side when finger contacts proximity sensor 560 The effect of the soft-touch control (contact-making switch) of door 21 sends finger to the control unit 556 of Figure 54 and contacts proximity sensor 560 Activation signal SH.Control unit 556 keeps the opening door operation of left-hand door 21 effective as a result, and control unit 556 acts enabling driving portion 54, Therefore it is able to carry out the enabling of left-hand door 21.

In addition, action example when user opens right door 22 as action example when above-mentioned opening left-hand door 21, therefore, is omitted Explanation.

In this way, when user contacts the proximity sensor 560 to work as contact sensor using finger, control unit 556 Left-hand door 21 or right door 22 can be made to automatically open.

When user only contacts proximity sensor 560, control unit 556 connects proximity sensor 560 (as touch sensor Touching sensor) it works, 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 where user touches 570 both sides of proximity sensor 560 and guard electrode shown in Figure 51 accidentally, control Portion 556 does not make proximity sensor 560 play the role of contact sensor, and makes the opening door operation engineering noise of left-hand door 21, as a result, not Carry out the opening door operation of left-hand door 21.Control unit 556 touches proximity sensor 560 in user accidentally such as ancon as a result, In the case where 570 both sides of guard electrode, makes 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 if shown in water droplet is attached to Figure 54 and Figure 51 in the case where 570 both sides of proximity sensor 560 and guard electrode, Control unit 556 makes the opening door operation engineering noise of left-hand door 21 and not making proximity sensor 560 work as contact sensor, Also the opening door operation without left-hand door 21.Forbidding for above-mentioned opening door operation is same for right door 22.

In addition, guard electrode 570 and intermediate region portion shown in the ancon while hookup 54 and Figure 51 of such as user In the case where point 589 both sides, the opening door operation " effective " of door 21 can be made and carry out the opening door operation of left-hand door 21.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 are respectively provided with electrostatic Touch type contact sensor, the electrostatic touch type contact sensor are used as the close proximity sensor of finger of detection human body etc. 560.As shown in figure 51, in substrate 553, around the proximity sensor 560 as electrostatic touch electrode, guard electrode 570 be configured to by with proximity sensor 560 have it is spaced in a manner of surround proximity sensor 560.

The guard electrode 570 be when human body is close, for change proximity sensor 560 human testing range it is effective The effective range change mechanism of the detection range of range.Guard electrode 570, which is generated, detects the close of human body with proximity sensor 560 When the electromagnetic field of electromagnetic field opposite direction that generates.

As a result, guard electrode 570 to proximity sensor 560 detect human body it is close when the electromagnetic field that generates in upper and lower It is limited on, left and right directions, as shown in Figure 49 and Figure 50, proximity test electromagnetism that limitation proximity sensor 560 generates The spreading range of field.Therefore, the electromagnetic field 560P (proximity test range) that proximity sensor 560 generates only is limited in close to sensing The positive forward direction of device 560.

Therefore, in the case where 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 It closes the door, 560 error detection of proximity sensor of right door 22 can be prevented, closed the door using the enabling of right door 22, left-hand door 21 can be prevented 560 error detection of proximity sensor.

In addition, coming refrigerator in human body or object in the case where not being opposite opened refrigerator but single open-door formula refrigerator Side in the case where, can prevent the careless erroneous detection of the proximity sensor of door from measuring the human body or object.

User presses with finger the behavior of proximity sensor 560 (contact), is usually with the center of proximity sensor 560 What target carried out, therefore, through-hole 560C is formed in the center position of proximity sensor 560.

The reasons why making through-hole 560C be formed in the center position of proximity sensor 560 like this, is as follows.I.e., it is passed for close For sensor 560, the middle section of through-hole 560C is formed compared with other regions, switchs sensitivity highest.Therefore, pass through use The finger pressing at family has the center close to switch 560 of through-hole 560C, can make finger contact sensitivity highest place.

Proximity sensor 560 shown in Figure 64 and Figure 65 is electrostatic touch (contact) electrode, is in Figure 62 and figure Front (front surface) direction of left-hand door 21 and right door 22 shown in 63 detects human body or object at for example, about 100mm Close electrostatic capacitance testing agency.A part specifically such as finger of the proximity sensor 560 in the human body of user When close, the close of the finger is detected.Proximity sensor 560 is electrostatic capacity type touch sensor, and mutual capacitance can be used Mode touch sensor or self capacitive way touch sensor.

For mutual capacitance mode, it is made of 1 sender electrode and 1 receiving electrode, is provided when to sender electrode When electric current, electromagnetic field is generated, electromagnetic field is received electrode reception.Such as the finger of human body is close to the detection of proximity sensor 560 When region, a part of electromagnetic field is absorbed and is received electrode reception, 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 sensor 560) with stray capacitance needs 1.Electrode (connects Nearly sensor 560) stray capacitance by being located at the electrode (proximity sensor 560) and the surrounding electric conductor (hand of human body Refer to) between effect of parasitic capacitance.When the finger of human body is close to proximity sensor 560, is influenced and made miscellaneous by parasitic capacitance The value of spurious capacitance increases, and by measuring the increased stray capacitance, proximity sensor 560 is capable of detecting when the close of finger.

As shown in Figure 64 and Figure 65, proximity sensor 560 is created as the switch for the oblong-shaped for example longitudinally grown, slit 574, it 575 is formed in a manner of surrounding electrode around proximity sensor 560.I.e., slit 574,575 is to surround close to sensing Mode around device 560 is formed along the Z direction.As a result, by setting slit 574,575, it is readily apparent that proximity sensor 560 Position.As shown in Figure 65, it is covered with such as thin transparent membrane body 576 on the slit 574,575, on thin transparent membrane body 576 Multiple light-emitting components to work as lighting device that is, LED577 are formed with across interval.

Wherein, as shown in Figure 65,4 corresponding 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 so set, with 4 corner 576R corresponding 4 The illumination light that a LED577 is generated is irradiated in a manner of it will not have an impact to slit 574,575.

As shown in Figure 65, the one end of proximity sensor 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 Link by by proximity sensor 560 and its peripheral part that is, in a manner of middle region part 589 connects, also referred to as " bridge ".Linking portion 560A, 560B are set to the position other than the above-mentioned position configured with LED577 in a manner of avoiding.By This, linking portion 560A, 560B will not interfere the illumination light of LED577.

Electrical connection through-hole 560C is formed in the central portion of proximity sensor 560.Like this in proximity sensor 560 Center portion forms through-hole 560C and is provided with the region part of the proximity sensor 560 of through-hole 560C as already described Compared with other region parts, detection sensitivity is high.The finger of user approaches and the region part contacted is proximity sensor 560 Center portion through-hole 560C is therefore disposed proximate to the center portion of sensor 560.

Next, being illustrated to guard electrode 570 shown in Figure 64 and Figure 65.

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

As a result, as shown in Figure 62 and Figure 63, the extension for the electromagnetic field 560P that proximity sensor 560 generates is by guard electrode The electromagnetic field of 570 opposite directions generated inhibits.Therefore, inhibited by the electromagnetic field generated by guard electrode 570 close to sensing The extension for the electromagnetic field 560P that device 560 generates, guard electrode 570 play the detection model of the effective range of change human testing range The effect for the effective range change mechanism enclosed.

Guard electrode 570 in a manner of constriction such as finger of alteration detection human body it is close when proximity sensor 560 detection range, the effective range of the detection range of Lai Biangeng proximity sensor 560.Specifically, guard electrode 570 becomes Closer to the detection range of sensor 560 effective range as a result, as shown in Figure 62, the opening door operation portion 551 of left-hand door 21 The electromagnetic field 560P that proximity sensor 560 generates is only channeled to the positive forward direction of proximity sensor 560.Equally, right door The electromagnetic field 560P that the proximity sensor 560 of 22 opening door operation portion 552 generates is only channeled to the front of proximity sensor 560 Forward direction.

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

Also, as shown in Figure 63, the electromagnetic field 560P that the proximity sensor 560 of the opening door operation portion 551 of left-hand door 21 generates It is only channeled to the positive forward direction of proximity sensor 560.Equally, the proximity sensor of the opening door operation portion 552 of right door 22 The 560 electromagnetic field 560P generated are only channeled to the positive forward direction of proximity sensor 560.Therefore, in Figure 63, close to biography Sensor 560 generate electromagnetic field 560P by not vertically that is, Z-direction extend in a manner of constriction.

I.e., the electromagnetic field 560P of proximity sensor 560 shown in Figure 62 and Figure 63 shows the effective of the detection range of human body Range, the effective range of the detection range of the human body be equivalent to from and proximity sensor 560 the different direction in front range (in the range of upper and lower left and right extension) different range.

Then, Figure 67 be indicate control unit 556, opening door operation portion 551,552, as the enabling driving portion of door opener 54, the block diagram of 55 etc. electrical connection.

As shown in Figure 67, control unit 556 is electrically connected to the proximity sensor 560 and protection electricity of opening door operation portion 551,552 Pole 570, enabling driving portion 54,55, multiple LED577 as lighting device.

Under the control of control unit 556, proximity sensor 560 is held in " high sensitivity " state.Finger enters work Shown in Figure 62 and Figure 63 for the detection zone of proximity sensor 560 when electromagnetic field 560P, the control unit 556 of Figure 67 is from close Sensor 560 receives the signal SG that finger has approached proximity sensor 560.

Moreover, the control unit 556 of Figure 67 is judged as finger when receiving the signal SG from the proximity sensor 560 Approached proximity sensor 560, and stopped the energization to guard electrode 570, and by the sensitivity of proximity sensor 560 from " high sensitivity " is changed to " muting sensitivity " to reduce sensitivity.Also, control unit 556 is being received from the proximity sensor When 560 signal SG, control unit 556 is illuminated by making LED577 bright light to close to around switch 560, utilizes illumination So that the position for approaching switch 560 is floated, allows users to the position with visual confirmation close to switch 560.

Then, when in finger from the state contacts proximity sensor 560 close to proximity sensor 560, proximity sensor 560 It works as contact-making switch, proximity sensor 560 sends the contact that finger contacts proximity sensor 560 to control unit 556 Signal SH.Control unit 556 makes proximity sensor 560 work as contact sensor as a result, grasps the enabling of such as left-hand door 21 Make effectively, control unit 56 can be such that enabling driving portion 54 acts and actually carry out the opening door operation of left-hand door 21.For right door 22 Speech, aforesaid operations sequence are same.

User touches while by illumination visual confirmation caused by LED577 as a result, is configured at left-hand door 21 or right door The position close to 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 sensor 560 from finger when close It is switched to " muting sensitivity ", proximity sensor 560 is made to work as contact sensor.When finger is close to proximity sensor 560, Control unit 556 is in order to make static switching 560 work as " proximity sensor ", and control unit 556 is by the spirit of proximity sensor 560 Sensitivity is set as "high", as a result, the function " effective " as " proximity sensor ".Therefore, control unit 556 does not make proximity sensor 560 work as " contact sensor ", and therefore, proximity sensor 560 makes the original function of conduct of opening door operation portion 551,552 Can left-hand door 21, right door 22 opening (opening door operation) engineering noise.

As described above, making the finger of user close to proximity sensor 560, when finger is entered as proximity sensor 560 Human testing range effective range electromagnetic field 560P when, proximity sensor 560 is by finger close to notice to control unit 556.Then, when from proximity sensor 560 by finger close to notice to control unit 556 when, control unit 556 is set, and is made The sensitivity for obtaining proximity sensor 560 is switched to " low " from "high".Also, control unit 556 makes the bright light of proximity sensor 560 Display becomes open state from closed state, and the position of proximity sensor 560 is expressed by LED577.Therefore, user It is capable of the position of one side visual confirmation proximity sensor 560, reliably contacts proximity sensor 560 with finger on one side.Control unit 556 make proximity sensor 560 as original function that is, " contact sensor " works, therefore, close by being contacted by finger The opening operation (opening door operation) of sensor 560, left-hand door 21 or right door 22 becomes " effective ".

The opening operation (opening door operation) of above-mentioned left-hand door 21 and the opening operation (opening door operation) of right door 22 equally, are omitted Its explanation.

As shown in Figure 64 and Figure 65, guard electrode 570 is configured around proximity sensor 560, is passed as a result, as close The electromagnetic field 560P of the effective range of the human testing range of sensor 560 is in positive direction (the front side of left-hand door 21 and right door 22 To), the close of manpower or finger is detected in the range of for example, about 100mm.At this point, the human body as proximity sensor 560 The electromagnetic field 560P of the effective range of detection range is limited and configuring guard electrode 570, so that in above-below direction and left Right direction is without extension.

The human testing range of proximity sensor 560 is limited by such (X-direction) in left and right directions as shown in Figure 62 The extension of effective range, as shown in Figure 62, to open left-hand door 21 along track shown in arrow 21K and make finger close to a left side When the proximity sensor 560 of door 21, the proximity sensor 560 for the right door 22 being closed can not be allowed to detect finger.Equally, it Open right door 22 along track shown in arrow 22K and make finger close to right door 22 proximity sensor 560 when, can not allow pass The proximity sensor 560 for the left-hand door 21 that closed detects finger.

Therefore, not as the electromagnetic field 560P of the effective range of the human testing range of the proximity sensor 560 of right door 22 It can enter in track when opening the left-hand door 21 as mobile mechanism.Equally, the people as the proximity sensor 560 of left-hand door 21 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 mobile mechanism.

Thereby, it is possible to prevent from opening left-hand door 21 or when right door 22, do not open and the right door 22 of side that is closed or The careless erroneous detection of proximity sensor 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, the human testing range of proximity sensor 560 is limited by (Z-direction) in above-below direction Effective range extension, when pulling out push-pull door 23 as mobile mechanism along the direction of the arrow, as connecing for left-hand door 21 The electromagnetic field 560P of the effective range of the human testing range of nearly sensor 560 and proximity sensor 560 as right door 22 The electromagnetic field 560P of the effective range of human testing range will not be entered in track when opening push-pull door 23.

As a result, when opening push-pull door 23, can prevent left-hand door 21 proximity sensor 560 and right door 22 close to biography The careless erroneous detection 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 section 570A and a pair of long side electrode section 570B is constituted.Such as before attachment of moisture left-hand door 21 shown in Figure 61 Panel 21A, which is attached to always the front panel 21A of the position of guard electrode 570, so that guard electrode 570 is due to moisture When detecting the variation of electrostatic capacitance, control unit 556 shown in Figure 67 opens enabling driving portion caused by proximity sensor 560 ( Door gear) 54,55 door opening action it is invalid.

Specifically, wiping surface or the right door 22 of the front panel 21A of left-hand door 21 using wet rag in such as user Front panel 22A surface when, if guard electrode 570 detects moisture, proximity sensor 560 perceived wet rag and As open state, even if in this way, control unit 556 shown in Figure 67 is by making enabling driving portion caused by proximity sensor 560 The door opening action engineering noise of (door opener) 54,55, it is also possible that left-hand door 21 or right door 22 will not be battered open.Prevent as a result, Left-hand door 21 is stopped or right door 22 is opened accidentally.

In addition, making to connect when control unit 556 contacts proximity sensor 560 again after user's finger contact protection electrode 570 The door opening action engineering noise of enabling driving portion (door opener) 54,55 caused by nearly sensor 560.In turn, control unit 556 with When contacting proximity sensor 560 while finger contact protection electrode 570 of family, drive enabling caused by proximity sensor 560 The door opening action engineering noise of dynamic portion (door opener) 54,55.

Thus, it is therefore prevented that in the case where 570 erroneous detection of guard electrode measures human body, left-hand door 21 or right door 22 are beaten accidentally It opens.

As shown in Figure 61, control operation portion 650 is provided on the inside of the front panel 21A of left-hand door 21, in control operation portion 650 lower part is provided with opening door operation portion 551.Therefore, in the proximity sensor of control operation portion 650 and opening door operation portion 551 Position between 560, the short side electrode section 570A of the guard electrode 570 configured with opening door operation portion 551.In Figure 64 and Figure 65 Short side electrode section 570A is also shown.

When wiping the control operation portion 650 on the surface of the front panel 21A of left-hand door 21 with wet rag in such as user as a result, 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 570A being divided to detect moisture, proximity sensor 560 has perceived wet rag and has become open state, even if in this way, Figure 67 institute The control unit 556 shown also can be by making the door opening action of enabling driving portion (door opener) 54 caused by proximity sensor 560 Engineering noise, and left-hand door 21 will not be battered open.Thus, it is therefore prevented that left-hand door 21 is opened accidentally.

In addition, the electrode gap of the interval HF and longitudinal direction of the lateral electrode gap of guard electrode 570 shown in Figure 65 It is bigger than the width MF of the finger HT of human body to be spaced RF.The interval HF and longitudinal electricity of the lateral electrode gap of guard electrode 570 The interval RF of clearance between poles can preferably be selected in the range of 15mm~75mm.Pass finger HT close to close in user as a result, Sensor 560 and when contacting, can prevent the careless contact protection electrode 570 of finger HT.

In addition, the interval HF of the lateral electrode gap of guard electrode 570 and the interval RF of longitudinal electrode gap are i.e. The curved ancon of human body is set to encounter the size that will not touch guard electrode 570.The lateral electricity of these guard electrodes 570 The interval RF of the interval HF of clearance between poles and longitudinal electrode gap can be selected in the range of such as 30mm~75mm.Pass through this Sample sets the size of guard electrode 570, even if with the hands holding pot or plate etc. in user, with curved ancon rather than hand Abutment proximity sensor 560 in the case where opening left-hand door 21 or right door 22, can also prevent ancon while contact is close 570 both sides of sensor 560 and guard electrode.User also can open left-hand door 21 or right door with finger with ancon as a result, 22。

Then, the holding structure example of the substrate 553 of left-hand door 21 and right door 22 is illustrated referring to Figure 68.Figure 68 is to indicate left-hand door 21 and right door 22 substrate 553 holding structure example figure.Figure 68 (a) is the main view of left-hand door 21 and right door 22, and Figure 68 (b) is Indicate the vertical of the construction of the inner end face 21T (the inner end face 22T of right door 22) of the left-hand door 21 of the holding structure of substrate 553 Body figure.Figure 68 (c) is the figure for indicating the example of cover 590.

As shown in Figure 68 (a), in the state of closing left-hand door 21 and right door 22, the inner end face 21T of left-hand door 21 and the right side The inner end face 22T of door 22 is toward each other.The rectangular opening portion 586 of storage space component 585 is located at each inner end Facial 21T, the storage space component 585 of substrate mounting body 500M are located at the inside of left-hand door 21 and right door 22.Substrate mounting body 500M is contained in the mode being inserted into storage space component 585 from opening portion 586.

Wherein, in the case where substrate mounting body 500M is inserted into storage space component 585 to store like this, such as Shown in Figure 66,572 side of configuration section of substrate 553 is in 590 side of cover, and 571 side of carrying part of electronic component is from electronics 571 side of carrying part of component is inserted into opening portion 586 and reaches the inboard of storage space component 585.

In this way, proximity sensor 560 and guard electrode 570 are configured at the surface of substrate 553, set at the back side of substrate 553 It is equipped with the carrying part 571 of electronic component, in the state that substrate 553 is held in left-hand door 21, the carrying part of electronic component 571 are located at 572 opposite side of configuration section of the substrate 553 of 586 side of opening portion as insert port.

As a result, in the case where substrate mounting body 500M to be inserted into storage space component 585 and store, operator's energy The position of 1st stage portion 553M and the 2nd stage portion 553N of the carrying part 571 of enough one side visual confirmation electronic components, on one side Substrate mounting body 500M is inserted into storage space component 585, therefore, can prevent from for substrate mounting body 500M being mistakenly inserted Direction of insertion.

It is closed after having stored substrate mounting body 500M using cover 590 opening portion 586.In the cover 590 Internal surface configurations have metallic object 591 as aluminium foil strip or iron plate.Metallic object 591 limits the conduct that proximity sensor 560 generates The electromagnetic field of the effective range of human testing range is the change for changing the effective range of detection range of proximity sensor 560 Mechanism.The metallic object 591 of effective range change mechanism as detection range is configured at the left-hand door as adjacent mobile mechanism Between 21 and right door 22.

By the way that metallic object 591 is configured at 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 sensor 560 of left-hand door 21 and the electromagnetic field of guard electrode 570 will not be to right doors 22 Proximity sensor 560 and the electromagnetic field side of guard electrode 570 affect.In addition, the proximity sensor 560 from right door 22 Electromagnetic field and guard electrode 570 electromagnetic field will not the proximity sensor 560 to left-hand door 21 and guard electrode 570 electromagnetic field Side affects.

Next, the action example in the case where opening such as left-hand door 21 to user referring to Figure 61~Figure 63 and Figure 67 is said It is bright.

Make finger close to the proximity sensor 560 of 21 side of left-hand door shown in Figure 62 and Figure 63 in user, and enters Figure 62 When with electromagnetic field 560P shown in Figure 63 as the effective range of human testing range, the proximity sensor of highly sensitive state 560 detect that finger has approached proximity sensor 560.The control unit 556 of Figure 67, which receives, as a result, indicates that finger has approached biography The signal SG of sensor 560.

Then, the control unit 556 of Figure 67 stops according to the signal SG from the proximity sensor 560 to guard electrode 570 Energization, and control unit 556 is reduced close to the sensitivity of sensor 560, so that being changed to from " high sensitivity " " low sensitive Degree ".Moreover, control unit 556 is illuminated by making LED577 bright light to close to switch 560, can express close to switch 560 Position, user be capable of visual confirmation close to switch 560 position.

Then, when finger contacts proximity sensor 560, the proximity sensor 560 of muting sensitivity, which is used as, is used to open a left side The soft-touch control (contact-making switch) of door 21 works, and the activation signal SH that finger contacts proximity sensor 560 is sent to figure 67 control unit 556.Control unit 556 keeps the opening door operation of left-hand door 21 effective as a result, and control unit 556 keeps enabling driving portion 54 dynamic Make, therefore left-hand door 21 can be made to open the door.

In addition, user open right door 22 in the case where action example and above-mentioned opening left-hand door 21 in the case where action example phase Together, and the description is omitted.

In this way, in the proximity sensor 560 that user uses finger contact to work as contact sensor, control unit 556 Left-hand door 21 or right door 22 can be automatically opened.

When user only contacts proximity sensor 560, control unit 556 connects proximity sensor 560 (as touch sensor Touching sensor) it works, make the opening door operation " effective " of left-hand door 21, thus carries 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 where user contacts 570 both sides of proximity sensor 560 and guard electrode shown in Figure 64 accidentally, control Portion 556 does not make proximity sensor 560 work as contact sensor, and makes the opening door operation engineering noise of left-hand door 21, as a result, not Carry out the opening door operation of left-hand door 21.Control unit 556 touches proximity sensor 560 in user accidentally such as ancon as a result, In the case where 570 both sides of guard electrode, makes 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 if examining proximity sensor 560 shown in Figure 64 and 570 both sides of guard electrode because of water droplet attachment In the case where measuring, control unit 556 does not make proximity sensor 560 work as contact sensor yet, and makes opening for left-hand door 21 Door operation engineering noise, the as a result, opening door operation without left-hand door 21.Above-mentioned opening door operation is forbidden for right door 22 Equally.

In addition, human body or object come refrigerator in the case where not being the refrigerator of the refrigerator of opposite opened but single open-type Side in the case where, can prevent the careless erroneous detection of the proximity sensor of door from measuring the human body or object.

In addition, proximity sensor 560 shown in Figure 64 detection user finger HT close " proximity test mode " and " the electrostatic touch mode " to work as contact sensor that proximity sensor 560 detects the contact of the finger HT of user can be with It switches over as follows.

As shown in Figure 64, the proximity sensor 560 as the 1st electrode and the middle region part 589 as the 2nd electrode connect It is connected to the microcomputer 599C of control unit 556.

Include: when being switched to " electrostatic touch mode " from above-mentioned " proximity test mode " as the case where switch mode, When with being switched to " proximity test mode " from " electrostatic touch mode ".

When being switched to " electrostatic touch mode " from " proximity test mode ", proximity sensor 560 detects finger HT's After, proximity sensor 560 of the microcomputer 599C cutting as the 1st electrode and the middle region part 589 as the 2nd electrode Inside connection, the electrostatic touch sensor only proximate to sensor 560 as " electrostatic touch mode " work.

On the contrary, finger HT is detached from proximity sensor 560 when being switched to " proximity test mode " from " electrostatic touch mode ", When passing through stipulated time, such as 10 seconds from " electrostatic touch mode ", or having carried out reset by shutdown etc. from enabling, microcomputer 599C connect as the proximity sensor 560 of the 1st electrode with the inside of the middle region part 589 as the 2nd electrode.

Then, the example that Figure 74 (a), 74 (b) show following scenario described: for the figure for making finger HT contact the 32nd embodiment In the case where the door 21 for opening left side shown in 51 and Figure 52 as the proximity sensor 560 of the 1st electrode, carry out as the 1st The switching of the proximity sensor 560 of electrode and the middle region part 589 as the 2nd electrode, the control operation portion 650 of left-hand door 21 With 560 bright light of proximity sensor.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 sensor 560.In this state, it controls In order to make the proximity sensor 560 as static switching work as " proximity sensor ", control unit 556 makes to approach in portion 556 Sensor 560 is opened and the sensitivity of proximity sensor 560 is set as "high" to improve sensitivity, as a result, as " close to biography The function " effective " of sensor ".Also, control unit 556 connect middle region part 589 and by the spirit of middle region part 589 Sensitivity is set as "high" to improve sensitivity, as a result, the function " effective " as " proximity sensor ".

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 shows that the bright light for controlling operation portion 650 and proximity sensor 560 Bright light is shown as " closed state ".Then, control switch (control button) 650CS and the HOME switch of operation portion 650 are controlled Operation (opening door operation) function engineering noise of (HOME key) 650HS.

Then, shown in Figure 74 (b) finger HT close to proximity sensor 560 state.In this state, close to biography Sensor 560 detects that finger HT's is close, and therefore, control unit 556 makes 560 open state of proximity sensor, will be close to sensing The sensitivity as " proximity sensor " of device 560 is switched to " low " from "high" to reduce sensitivity, weakens proximity sensor Function disconnects middle region part 589.

Therefore, control unit 556 makes proximity sensor 560 as contact sensor and works, and therefore, finger HT is from front panel Surface contact the proximity sensor 560 that works as contact sensor, the opening operation of the left-hand door 21 thus excited (is opened Door operation) function from engineering noise becomes " effective ".

Also, control unit 556 shows that the bright light for the LED for controlling operation portion 650 with the LED's of proximity sensor 560 Bright light, which is shown, becomes " open state ", as the LED lighting lamp state of the two, such as carries out pico- bright light.I.e., shown in Figure 58 The pico- bright light of LED665 as a result, from behind illuminates control operation portion 650 and is shone, and LED577 shown in Figure 52 is pico- Bright light, the proximity sensor 560 to work as contact sensor is illuminated from behind from there through slit 574,575 and It shines.In such a situation it is preferred that the bright light shows that the time is the time such as 10 seconds as defined in bright light, during this 10 seconds, In the case where finger HT does not contact proximity sensor 560 worked as contact sensor, also may again be such that LED635,577 are turned off the light.

Wherein, control unit 556 can be set as: make the movement that the LED665 bright light of operation portion 650 is controlled shown in Figure 58 Movement start time (the bright light of LED577 bright light of the start time (bright light opportunity) than making proximity sensor 560 shown in Figure 52 Opportunity) delay scheduled delay time, i.e., keep the two different.I.e., control unit 556 can change control operation portion 650 The opportunity of the illumination mode of the LED577 on the opportunity and proximity sensor 560 of the illumination mode of LED665.Such as proximity sensor The bright light opportunity of 560 LED577 can be earlier than the bright light opportunity of the LED665 of control operation portion 650.But it on the contrary, can also be with So that bright light opportunity of the bright light opportunity of the LED665 of control operation portion 650 earlier than the LED577 of proximity sensor 560.Pass through picture Make bright light opportunity different in this way, user can be directed to, position, proximity sensor 560 and the intermediate region of operation portion 650 will be controlled The position of part 589 distinguishes display.

Then, the operating function for controlling the control switch 650CS and HOME switch 650HS of operation portion 650 is opened, from " nothing Effect " becomes " effective ".

Then, it in Figure 74 (c), shows finger HT and contacts the proximity sensor 560 to work as contact sensor State.In this state, control unit 556 maintains the sensitivity as " contact sensor " that is, " low " of proximity sensor 560 State.Control unit 556 makes the function of the proximity sensor 560 to work as contact sensor that is, the opening of left-hand door 21 is grasped Making (opening door operation) function maintains " effective " constant.Also, the bright light shape that the bright light of the LED as proximity sensor 560 is shown State, control unit 556 change illumination mode, become common bright light from pico- bright light.

I.e., LED665 shown in Figure 58 carries out common bright light, as a result, from behind to control operation portion 650 with brighter Bright mode is illuminated and is shone, also, LED577 shown in Figure 52 carries out common bright light, as a result, by slit 574, 575 from behind illuminate in a manner of more becoming clear the proximity sensor 560 to work as contact sensor and are shone. I.e., in the finger HT contact of Figure 74 (c), the bright light of light quantity and proximity sensor 560 that the bright light of control operation portion 650 is shown The light quantity of display rises to usual bright light from glimmer lamp, is shone with the complete bright light based on bigger light quantity progress, is approached as a result, The bright light of sensor 560, which is shown, to be become more to become clear.Control unit 556 makes the lighting lamp state for controlling the LED of operation portion 650 also from micro- Glimmer lamp becomes common bright light.

Then, control button (control switch) 650CS and HOME key (HOME switch) 650HS of operation portion 650 is controlled Operating function open, be " effective ", therefore can operate.

As a result, user with finger to proximity sensor 560 carry out touch operation and make the opening door operation of left-hand door 21 at In the case where vertical, LED577 becomes complete bright light from pico- bright light and improves light quantity, and therefore, user can pass through the increasing of bright light amount Add and visual confirmation opening door operation has been set up.Also, user can more reliably identify control operation portion 650 display and The display of LED577, and can be improved the energy-saving effect of power consumption.

As described above, being contacted in the case that the finger HT shown in such as Figure 74 (b) is close to proximity sensor 560 in finger HT When touch controlled key 633 shown in Figure 74 (c), control unit 556 carries out illumination and the proximity sensor 560 of control operation portion 650 Therefore illumination can change light quantity when improving bright light as described above.

Later, in Figure 74 (d), show user finger HT be detached from as contact sensor work close to sensing 560 state of device.In this state, control unit 556 keeps the input of the operation signal from proximity sensor 560 effective, to make out Door driving portion 54 acts, and carries out the enabling control of corresponding left-hand door 21 as a result,.Left-hand door 21 can automatically open as a result,.Then, Control unit 556 makes the function engineering noise of the proximity sensor 560 to work as contact sensor.

Also, control unit 556 make control operation portion 650 bright light show with the slit 574,575 of proximity sensor 560 at LED577 bright light show as shown by the solid line as, maintain " open state ".Then, the control for controlling operation portion 650 is opened The operating function for closing 650CS and HOME switch 650HS is closed, and becomes engineering noise from " effective ".

As described above, as the opening action of the left-hand door 21 illustrated referring to Figure 74, for using right door shown in Figure 56 The opening action of the right door 22 of 22 opening door operation portion 652 can also carry out.

Next, illustrating that proximity sensor 560 detects the principle of the contact of finger referring to Figure 75.Figure 75 is to indicate close Sensor 560 detects the circuit diagram of the principle of the contact of finger HT.

Contact detection circuit 888 shown in Figure 75 includes the proximity sensor 560 as contact sensor (Cx), adjustment Capacitor (Cmod) 889, clock generating source 890, IDAC (electric current output digital analog converter) 891, latch 892, timer 893, AND (with) circuit 894, counter 895.IDAC891 make every time identical electric current in a pulsed fashion multi-reflow to conduct The proximity sensor (Cx) 560 and adjustment capacitor (Cmod) 889 of contact sensor, lodge in charge gradually and pass as contact The proximity sensor (Cx) 560 and adjustment capacitor (Cmod) 889 of sensor.To the proximity sensor as contact sensor (Cx) 560 and adjustment capacitor (Cmod) 889 continues to accumulate charge until becoming with current potential, and counter 895 is to until in adjustment capacitor The number of pulse until the accumulation regulation charge of device (Cmod) 889 is counted.

When finger HT proximity sensor 560 of the contact as contact sensor (Cx), as contact sensor close to biography The electrostatic capacitance of sensor (Cx) 560 increases, and therefore, the charge for flowing to adjustment capacitor (Cmod) 889 and accumulating tails off, and arrives charge The time is spent until adjustment capacitor (Cmod) 889 completes to accumulate, therefore, the pulse that counter 895 is counted Count number increases (slope is gentle), therefore, as a result, the displacement of slope changes.Determined with the difference of the displacement of the slope The presence or absence of finger.I.e., the count number of the pulse counted in counter 895 reaches super from common count number (basis counts) When crossing the value of certain threshold value, control unit 556 is judged as that finger HT contacts the proximity sensor as contact sensor (Cx) 560。

Then, the change side of sensitivity when contacting proximity sensor 560 as contact sensor (Cx) to finger HT Method is illustrated.

As the variation of sensitivity, when reducing the current value of IDAC891, if lodging in proximity sensor (Cx) 560 quantity of electric charge is identical, then the time for end of charging lengthens, and becomes flat.In the time slack that flattens, judged with same threshold In the case where, 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 When state, the variation of slope increases, and is well over threshold value, and sensitivity increases.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 variation of slope reduces, it is difficult to be more than threshold value, Sensitivity is small.

I.e., compared with being more than threshold value for the first time when contacting with entire finger and the state that detects, reduce current value, by This can be improved sensitivity even if only also being able to detect out with finger tip contacts.Although in addition, also can by reducing threshold value Improving sensitivity can still be detected due to there is noise also, with above-mentioned sensitivity variation Change sensitivity.

Then, Figure 76 is the figure for indicating the essential structure of proximity sensor.

As shown in Figure 76, proximity sensor 560 and copper are grounded 569 between coating 560R and dielectric layer 560D, Connecing when the electrostatic capacitance CF capacitor after being added of the electrostatic capacitance CP and finger HT of proximity sensor 560 itself contact for finger The electrostatic capacitance CX of nearly sensor 560.

In the movement that finger HT carries out electrostatic touch to proximity sensor 560, approaching when finger HT contact is detected The variation of the electrostatic capacitance CX of sensor 560.In addition, being detected in movement of the detection finger HT close to proximity sensor 560 The variation of the electrostatic capacitance CP of proximity sensor 560 itself when finger is close.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 variation.Electrostatic capacitance CP is that the electric field in 3 dimension directions slightly changes when finger is in electric field, by This, the electrostatic capacitance CX of entire proximity sensor changes, and the detection of finger is able to carry out by above-mentioned detection.

Next, Figure 77 be for shown in Figure 74 as the 1st electrode that is, contact sensor works close to sensing Device 560 and middle region part 589 as the 2nd electrode, handover operation when illustrating close to mode and electrostatic touch mode Figure.

As shown in Figure 77, as the 1st electrode that is, proximity sensor 560 that contact sensor works and 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 The instruction of 556M makes proximity sensor 560 and middle region part 589 carry out internal connection, or can release internal connection.

(1) from the switching action switched close to mode to electrostatic touch mode when

In the case where carrying out from the switching action switched close to mode to electrostatic touch mode, such as Figure 74 (a)~Figure 74 (b) shown in, finger HT is close to proximity sensor 560, when proximity sensor 560 detects finger HT, from close to pattern switching to Electrostatic touch mode.I.e., according to the instruction of the microcomputer 556M of Figure 77, multiplexer 556R makes proximity sensor 560 and centre Region part 589 becomes the releasing state of internal connection, cutting proximity sensor 560 and intermediate region portion from internal connection state Divide 589 connection.Only have proximity sensor 560 as a result, to use middle region part as a result, as electrostatic contact sensor 589 disconnect, and are not used.

(2) when from electrostatic touch mode to the switching action close to pattern switching

On the contrary, the case where carrying out from electrostatic touch mode to the switching action close to pattern switching, is touched from such as electrostatic The case where mode is touched by 10 seconds, or is reset from the opening of door by the closing etc. of door.In this case, according to microcomputer The instruction of 556M, the releasing state that multiplexer 556R is connect from proximity sensor 560 with the inside of middle region part 589 Back to internal connection state, proximity sensor 560 and middle region part 589 can be connected.

In turn, referring to Figure 48~Figure 50.In Figure 48~Figure 50,560 He of proximity sensor as the 1st electrode is shown The modification of the proximity test effective range of middle region part 589 as the 2nd electrode.

The proximity test effective range of proximity sensor 560 when the proximity sensor 560 as the 1st electrode is used only, It is the range of roundlet HC1.Then, by the basis of proximity sensor 560 and being used as the middle region part of the 2nd electrode 589, the proximity test effective range of proximity sensor 560 can extend model in a manner of expanding to great circle HC2 from roundlet HC1 It encloses.

But when to extend proximity test effective range like this, in the proximity test of the proximity sensor of great circle HC2 Under effective range, as mobile mechanism adjacent door 21 (or door 22), be placed in door back side door compartment water bottle The instruction for opening door is issued etc. the proximity test effective range that can react on proximity sensor 560, it is possible to so that being not desired to beat The door for opening side is opened accidentally.

Therefore, in order to carry out proximity sensor 560 proximity test effective range change, as the effective model of proximity test The change mechanism enclosed is provided with shown in the grounding pattern 573 and Figure 51 (a) shown in Figure 78 and Figure 51 (b) as the 4th electrode Guard electrode 570 as the 3rd electrode.

Figure 78 is the figure for illustrating the change close to range of proximity sensor 560 and middle region part 589.

As shown in Figure 78, in the back side 553B corresponding with configuration section 572 of substrate 553 as shown in Figure 51 (b) The upper netted grounding pattern 573 configured with as the 4th electrode.The grounding pattern (mesh electrode) 573 covers proximity sensor 560 With the substrate 553 of the back side of middle region part 589.By making the electricity identical as proximity sensor 560 of grounding pattern 573 Pressure does not form electric field from proximity sensor 560 and middle region part 589 to grounding pattern 573.Thereby, it is possible to change electric field Range will be not desired to the range detected by proximity sensor 560 removing.Electric field from grounding pattern 573 is only to proximity sensor 560 and 589 direction of middle region part generate electric field, offset from proximity sensor 560 and middle region part 589 towards ground connection The electric field of pattern 573 disappears (elimination) towards the electric field of the back side direction of substrate 553.

As a result, as shown in Figure 78 (a), when the back side of substrate 553 configures the grounding pattern 573 as the 4th electrode, approach The proximity test range DL1 of sensor 560 and middle region part 589 can be greater than proximity test range 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 range A shown in Figure 49, or disappears.

In addition, the guard electrode 570 of frame-type is configured at substrate 553, the encirclement of guard electrode 570 connects as shown in Figure 51 (a) Nearly sensor 560 and middle region part 589, the electric field of left and right directions is reduced corresponding with range U shown in Figure 49 as a result, Amount.As a result, as shown in Figure 48~Figure 50, the proximity test effective range of proximity sensor 560 can be changed to small from great circle HC2 Shape HC3 reduce amount corresponding with range V in above-below direction moreover, as shown in figure 50.

In this way, the proximity test effective range of proximity sensor 560 is as shown in the small shape HC3 of Figure 50, on the whole, only There is the forward direction of the proximity test range DL1 of proximity sensor 560 and middle region part 589 to stretch out, it can be in distance In the range of carry out proximity test.In addition, even if metallic object 591 shown in setting Figure 53, can also make electric field have an effect, have So that the proximity test effective range of proximity sensor is no more than the function of metallic object 591, proximity sensor can be further prevented Caused error detection.

Figure 71 is to indicate control unit 756, operation detection part 701, as the electricity of the enabling driving portion 54,55 of door opener etc. The block diagram of connection.

As shown in Figure 71, control unit 756 be electrically connected to operation detection part 701, enabling driving portion 54,55, multiple LED735, Range determination mechanism 777.

In the refrigerator 1 shown in Figure 69, in the case where user opens left-hand door 21 (or right door 22) of refrigerator 1, if Dim environment, then carried out in user with finger by operation detection part 701 it is non-contact caused by operation when, it is difficult to see behaviour Make the position of each proximity sensor 711~714 of test section 701.In this way, being difficult to carry out each proximity sensor 711 to improve ~714 operation is equipped with LED735 at the back side of each proximity sensor 711~714 respectively.

Proximity sensor 711~714 detects the side of finger, palm (metacarpus, the back of the hand), hand according to scheduled particular order Portion, ancon it is close when, control unit 756 receives the close signal of notifier from each proximity sensor 711,712,713,714, because This, control unit 756 makes left-hand door 21 or right door 22 by enabling driving portion 54 as door opener or enabling driving portion 55 Carry out door opening action.

At this point, control unit 756 receives the close signal of notifier from each proximity sensor 711,712,713,714, therefore, According to the instruction of control unit 756, LED735 being capable of bright light.

Even if user is under dim environment as a result, also it is capable of each proximity sensor of visual confirmation operation detection part 701 711,712,713,714 position, can each proximity sensor 711,712,713,714 easy to operate, left-hand door 21 can be opened (or right door 22).

As described above, the operation detection part 701 of the 33rd embodiment carries out the operation of people not by contact detection Detection, but left-hand door 21 or right door 22 are opened by non-contact detecting.In the case where opening door by contact detection, need Finger contact contact detecting point is wanted, in the state that thing is held in user hand, it is difficult to open door, or need to be beaten with ancon It opens the door.In this regard, operation detection part 701 is able to suppress use by using the Touchless manipulation for not needing contact contact detecting point The door opening action unintentionally of user caused by the movement at family, the variation of ambient enviroment.

Each proximity sensor 711,712,713,714 of operation detection part 701 shown in Figure 69 and Figure 70 is by being made The mobile movement such as finger, palm (metacarpus, the back of the hand), the side of hand, ancon of user, i.e., so-called posture can be connect with non- Touching mode opens left-hand door 21 or right door 22, by not needing the Touchless manipulation of contact contact detecting point, is able to suppress use The door opening action unintentionally of user caused by the movement at family, the variation of ambient enviroment.

As shown in Figure 69, each proximity sensor 711,712,713,714 of operation detection part 701 is with identical interval, Up and down direction (direction VT) and left and right directions (direction HL) two-dimensional arrangement, it is preferable that be respectively arranged at 4 corners of square.With Hand, the ancon at family etc. relative to operation detection part 701 each proximity sensor 711,712,713,714 in a non contact fashion according to Specific sequence (up and down direction, left and right directions, oblique) is mobile, and thus the control unit 756 of Figure 71 identifies each proximity sensor 711, the movement of 712,713,714 fingers, palm, the side of hand, ancon detected.Control unit 756 plays following work as a result, With: the enabling driving portion 54 of driving such as left-hand door 21 drives the enabling of right door 22 to drive to open left-hand door 21 or control unit 756 Portion 55 opens right door 22.

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

In use example described below, illustrate to make bimanual finger hold article in user, such as plate, pot and In the state that both hands take, finger is not available by contacting come proximity sensor 711~714 shown in operation diagram 69, is carried out Such as left-hand door 21 (or right door 22) door opening action the case where.

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

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

Figure 72 shows movement (posture) of the user using palm, the side of hand or ancon etc. to proximity sensor 711 ~714 carry out the example of Proximity operation with scheduled particular order.

The particular order refer to the palm, hand that make user side or ancon into proximity sensor 711~714 extremely Few 2 or more proximity sensors are predetermined close to mobile path.

Particular order shown in Figure 72 (a) is by the palm of user, the side of hand or ancon along arrow institute to the right The 1st direction DD1 shown is mobile, and 2 proximity sensors 711,712 successively detect human body (palm, the side of hand or ancon), And by being moved along with the 2nd direction shown in the arrow to the left different from the 1st direction DD1 (opposing direction) DD2,2 Proximity sensor 712,711 successively detects obtained from human body (palm, the side of hand or ancon).

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: carrying out the function of the door opening action of left-hand door 21 by enabling driving portion 54 to the instruction of such as control unit 756.

Other particular order shown in Figure 72 (b) is: by the palm of user, the side of hand or ancon along with to 1st direction DD1 shown in right arrow is mobile, and 2 proximity sensors 711,712 successively detect the human body (side of palm, hand 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 sensor 712,713 successively detects obtained from human body (palm, the side of hand or ancon).

In this case, the 1st direction DD1 and the 3rd direction DD3 constitutes the 2nd specific direction F2, the 2nd specific direction F2's Particular order indicates so-called " air cooling is frozen " function to control unit 756, that is, indicates: receiving to the conduct for allowing hand over such as refrigerator 1 Receive the function of sharply being freezed in refrigerator shown in such as Figure 69 of room in the switching chamber 14 of set temperature.It is somebody's turn to do " air cooling is frozen " Function be a gas cellular damage of -1 DEG C~-5 DEG C of the temperature band come freezing-inhibiting when is frozen by food water, protect Hold the function of well tasting.

As described above, by the movement (posture) of user's palm, the side of hand or ancon etc. to proximity sensor 711 At least two proximity sensor in~714 carries out Proximity operation with scheduled particular order can beat as scheduled function It creates a precedent such as left-hand door 21, or the right door 22 of opening.

Even if proximity sensor 711~714 is configured at left-hand door 21 or right door 22 as a result, can also prevent in user When only passing through before refrigerator 1, left-hand door 21 or right door 22 are opened.

In addition, Figure 73 is the example for indicating to carry out proximity sensor with other scheduled particular orders Proximity operation Figure.

As shown in Figure 73, it in the state that user holds plate, pot etc. using both hands finger and both hands take, cannot use When the finger of both hands carries out Proximity operation to proximity sensor 711~714, pass through the side using palm (metacarpus, the back of the hand), hand Portion, ancon etc. detect proximity sensor 711~714 according to scheduled particular order in a non contact fashion, also can be right The indicating predetermined any function of control unit 756.

Make palm (metacarpus, the back of the hand), the side of hand, ancon movement and carry out mobile direction can upper and lower in any combination To, left and right directions, it is oblique in 2 or 3 or more directions come using.

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