Fig. 7 c represents the occasion detected successively to switch c from switch b.In this occasion, detecting distance is short, and no matter whether user opens door separately consciously, is all envisioned as the finger of operation or hand slides, or position is departed from, and it is invalid that the input of therefore opening multiple is judged as.And, open separately the door (occasion detected at the first door open switch 48a is first 2a, and the occasion detected at the second door open switch 48b is second 2b) of the input detected to testing agency (the first door open switch 48a or the second door open switch 48b).

In addition, making to need the number of the sense switch detected to be at least more than three in multiple sense switch a, b, c, d is consider operability.That is, be in order to, even if from out to out whole by not drawing the operation display part 201 opposed with multiple sense switch a, b, c, d with hand, are also identified as and there is input, improve ease of use.On the other hand, make maloperation prevent preferential occasion, also for make whole occasions detected of multiple sense switch a, b, c, d, the structure opening input with multiple can be identified as.

" independent, multiple the opening of door judges flow process "

Then, illustrate that judging is open separately door or simultaneously or open the control flow of multiple successively according to Fig. 8.Fig. 8 represents that the independent door of the decision of embodiments of the present invention opens the flow chart inputting and open the condition of input with multiple door.Namely, be the mode of the switching manipulation represented according to user, carry out opening the operation of door or carrying out operating the flow chart of (make each sense switch detect in orientation successively and open the action of multiple) or an example of the judgement of maloperation in the mode making finger or hand draw in the orientation of each sense switch a, b, c, d.

First, wait in (S200) in door open switch (testing agency) input, wait for the input of the first door open switch 48a or the second door open switch 48b.Having the occasion (S201YES) of switch input, the i.e. detection of testing agency, make each initialization of variable (S202).At this, each variable set up timing A (time of the malfunction preventing vibration when being inputted by above-mentioned switch or interference etc. from causing, be 0.08 [s] in an embodiment), timing B (making long-time, invalid with the input of at least any one occasion contacted of sense switch a to the d time, is 1 [s] in an embodiment).In addition, the adjacent switch that the sense switch being used for judging to adjoin detects simultaneously is detected number of times be simultaneously initialized as 0.Before timing A terminates (front through 0.08 [s] in an embodiment) (S204NO), the occasion (S203YES) that whole switch input disconnects is judged as the faulty operation that vibration when being inputted by switch or interference etc. cause, and determines faulty operation (S209).Continue the occasion (S204YES) of timing A time more than in switch input, judge whether to produce the adjacent switch that adjacent sense switch detects input in order simultaneously and detect (S207) simultaneously.Its result, detect at satisfied adjacent switch simultaneously, and it is front through timing B time (being 1 [s] in an embodiment) (S208NO), whole switch inputs disconnects the occasion of the condition of (finger or hand leave) (S205YES), determines the action (S210) of opening separately door.

Further, utilize door opener 60 to open to have by the door of the door open switch operated (be first 2a in the occasion of operation first door open switch 48a, be second 2b in the occasion of operation second door open switch 48b).

In the occasion (occasion sense switch detects always) (S208YES) through timing B time (being 1 [s] in an embodiment), be judged as unconscious operation, determine maloperation (S209).

The occasion (S207YES) being judged as having adjacent sense switch and detecting at the adjacent switch that orientation detects simultaneously simultaneously, timing C (the input binding hours of sense switch a to d is set, be 5 [s] in an embodiment) (S213), upgrade adjacent switch and detect number of times (adding 1) (S214) simultaneously.At this time point, because adjacent switch detects number of times=1 simultaneously, therefore, what the adjacent switch of S215 detected number of times simultaneously judges that (being more than twice in an embodiment) is as NO.Until have new switch input (S211 be NO during), disconnect (finger or hand leave) (S216YES) in the input of whole switches, or timing C terminates the occasion of (in an embodiment through 5 [s]) (S217YES), determines the action (S210) of opening separately door.

Having the occasion (S211YES) of new switch input, judging whether that the adjacent switch that the switch that generation adjoins detects in orientation simultaneously detects simultaneously at S212.At this, be called the occasion detected to the input to sense switch do not detected adjoined with the sense switch that have detected input in multiple sense switch.In the occasion (S212NO) that not adjacent switch detects simultaneously, determine that independent door is opened (S210).

The occasion (S212YES) there is adjacent switch detecting simultaneously, again arrange timing C (when switching sequence detects, the input binding hours of sense switch a to d, be 5 [s] in an embodiment) (S213), upgrade adjacent switch and detect number of times (adding 1) (S214) simultaneously.At this moment, because adjacent switch detects number of times=2 simultaneously, therefore, what the adjacent switch of S215 detected number of times simultaneously judges that (being more than twice in an embodiment) is as YES, the while of determining multiple or open successively (S218).

In addition, wanting the occasion opening input cancelling door, carrying out along after the action of multiple sense switch is drawn in a direction of orientation, carrying out the action of drawing sense switch in the mode returning to the position of streaking in the opposite direction, namely to a side in this condition.Thus, be judged as that input is cancelled.

" utilizing the detection action of sense switch "

Then, the detection action utilizing sense switch is described according to Fig. 9.Fig. 9 is the figure of the detection action of the sense switch representing embodiments of the present invention.In mode 1, switch a is only had to connect.When making finger move to diagram right direction (mode 2), sense switch b also connects, and sense switch a and sense switch b all connects, and namely adjacent sense switch is connected each other simultaneously.When making finger move to diagram right direction further (mode 3), sense switch b is only had to connect.

When making finger move to diagram right direction further (mode 4), sense switch c also connects, and sense switch b and sense switch c connects, and namely again produces adjacent sense switch and connects each other simultaneously.Now, determine that multiple door is opened.After mode 3, point to oppositely (diagram left direction) mobile, and the occasion of echo plex mode 1 again, the moving direction of sense switch input is not " successively ", is therefore false.In addition, even right direction (clockwise direction), the occasion (mode 7) etc. that the adjacent sense switch of the occasion (mode 6) that the occasion (mode 3) connected only having sense switch c without mode 4, sense switch c and sense switch d all connect and more than three is connected, the detection of sense switch neither " successively ", therefore, the input that multiple door is opened is false.In addition, in fig. 8, before S207, be not so good as S212 judge that the input of new switch considers from the initial occasion producing adjacent switch and detect simultaneously like that.

" opening action of door and the detection action of sense switch "

Can with according to user's finger or hand directly touches or proximity test mechanism draws direction (direction that multiple sense switch detects successively), the mode that the order that multiple door is opened is different sets.Such as, as Fig. 7 a, in the occasion that sense switch detects from end side successively to another side (from left to right), open first 2a (refrigerating-chamber door in left side), then, second 2b (refrigerating-chamber door on right side) is opened.On the other hand, as Fig. 7 b, in the occasion that sense switch detects from other end side direction end side (from right to left), open second 2b (refrigerating-chamber door on right side), then open first 2a (refrigerating-chamber door in left side).

Namely, configuration by the revolving door (first 2a, second 2b) of the configuration with left and right that make sense switch a, b, c, d of the left and right directions of formation testing agency 48 is corresponding, the operation input of testing agency 48 is drawn in direction from from the reveal thinking first to open to the reveal opened afterwards, selects the opening sequence of door.

Such as, want the operation by the first door open switch 48a, after first opening first 2a, opening the occasion of second 2b, operate the first door open switch 48a (with reference to Fig. 7 a) in the mode of drawing from left to right.In addition, want the operation by the first door open switch 48a, after first opening second 2b, opening the occasion of first 2a, operate the first door open switch 48a (with reference to Fig. 7 b) in the mode of drawing from right to left.

On the other hand, want the operation by the second door open switch 48b, after first opening first 2a, opening the occasion of second 2b, operate the second door open switch 48b (with reference to Fig. 7 a) in the mode of drawing from left to right equally.In addition, want the operation by the second door open switch 48b, after first opening second 2b, opening the occasion of first 2a, operate the second door open switch 48b (with reference to Fig. 7 b) in the mode of drawing from right to left.

Thus, no matter the position relationship of the use hand of user or user and refrigerator, can select to open separately any one of multiple with single operation or open multiple door, open the occasion of multiple further, can select the order opening multiple, can be improved the operability of ease of use.
