Magnitude X) it is detected, and testing result is notified to opening control device 33.Currently, will be shone before the control of aperture starts
Bright device 34 extinguishes.
Opening control device 33 judges whether notified direct capacitance magnitude X is more than defined threshold X min (S1), not
(S1 in the case of being more than:NO), it is back to step S1.Threshold X min be for example set as in the same manner as above-mentioned desired value for example with
The corresponding values of 10cm or so.
(the S1 more than defined threshold X min:YES), it is transferred to step S3, that is, start to refrigerating-chamber door 15
The control of aperture instruction is lighted to the transmission of illumination control apparatus 35, thus illumination control apparatus 35 also, in step s3

Fig. 4 is the figure for the situation for showing that refrigerating-chamber door follows the hand of user and is opened and closed.Fig. 4 is recorded as seeing from top
It examines and schemes obtained from refrigerator.
In the case where the user for noticing that lighting device 34 has been lighted makes hand etc. far from refrigerating-chamber door 15, static capacity
Value gets lower than desired value, and therefore, aperture increases, that is, as shown in Fig. 4 (a), refrigerating-chamber door 15 is close to hand.That is, refrigerating-chamber door
15 follow the action of hand.In the case where refrigerating-chamber door 15 is closed, refrigerating-chamber door 15 can be made to open.It is cold when making hand stop
Room door 15 is hidden also to stop.
On the other hand, in the case where user makes hand close to refrigerating-chamber door 15, direct capacitance magnitude becomes to be above desired value,
Therefore, aperture reduces, that is, as shown in Fig. 4 (b), refrigerating-chamber door 15 is far from hand.That is, refrigerating-chamber door 15 follows the action of hand.When making
When hand stops, refrigerating-chamber door 15 also stops.When refrigerating-chamber door 15 is far from hand, refrigerating-chamber door 15 may turn off soon.
In such manner, it is possible to which the distance between the hand of user and refrigerating-chamber door 15 are kept constant, that is, refrigerating-chamber door can be made
15 follow the action of hand, additionally it is possible to carry out the opening and closing of refrigerating-chamber door 15.For example, user hand by the object of refrigerator to be accommodated in
In the case that product occupy, refrigerating-chamber door 15 is opened by keeping ancon etc. and distance detection device 32 close, thus compared with
For convenience.
In addition, if using solenoid to the refrigerating-chamber door 15 of the lighter in weight of the storage item in pocketed portion as previous
It is pushed and is opened it, then refrigerating-chamber door 15 can be violently opened.For the weaker user of strength, it is difficult to block
Refrigerating-chamber door 15, to more inconvenient.It therefore, can with minimal power and freely by carrying out above-mentioned aperture control
Refrigerating-chamber door 15 is opened and closed, to which convenience is improved.
In addition, if being pushed and being opened it to refrigerating-chamber door 15 as in the past, refrigerating-chamber door 15 can be excessive
It opens, so that the temperature in refrigerator is increased to required temperature or more because cold air escapes, still, by carrying out above-mentioned aperture control
Aperture, can be set as required minimum limit and ice the temperature inside the box is inhibited excessively to increase by system.
Fig. 3 is back to continue to illustrate.
(the S5 at direct capacitance magnitude X and desired value Xs unanimous circumstances:X=Xs), alternatively, it is split in step S7, S9
After degree is adjusted, S11 is entered step.In step s 11, opening control device 33 to it is defined per unit time in it is quiet
The variation delta (hereinafter referred to as direct capacitance magnitude variable quantity) of capacitance value and defined value Δ th are compared (S11).It is worth Δ
The speed of hand when th is for example redefined for making hand leave from door with user is corresponding to be worth.
(the Δ in the case where being determined as variation delta exceedance Δ th>Δ th), it is transferred to step S13, that is, terminate split
The control of degree, also, in step s 13, illumination control apparatus 35 is sent and extinguishes instruction, to which illumination control apparatus 35 makes photograph
Bright device 34 extinguishes (S13).After the extinguishing of lighting device 34, it is back to step S1.
For example, user wants to open refrigerating-chamber door 15 and hand is made to act, reaches required when making aperture and open
When spending, hand is set to be left from refrigerating-chamber door 15 due to wanting to take out the article put in refrigerator, it is determined as in S1
YES.Terminate the control to aperture as a result, lighting device 34 is extinguished.It, can be by aperture control by extinguishing lighting device 34
The information that system terminates is notified to user.
Even if in addition, it is assumed that if also continuing with control in the case where user makes hand be left from refrigerating-chamber door 15,
Then driving current continues to flow in the stepper motor 311 of Fig. 2, and the possibility to break down increases.Therefore, in embodiment party
In formula, in Δ>Finishing control in the case of Δ th, thereby, it is possible to prevent the generation of above-mentioned this failure.
In the opening procedure of refrigerating-chamber door 15 in the case of finishing control, aperture is kept constant.Even if as a result, careless
In the case of touching the position other than the distance detection device 32 of refrigerating-chamber door 15, refrigerating-chamber door 15 will not be acted,
So as to be easy to carry out the storage of food, take out.
On the other hand, the refrigerating-chamber door 15 in opening procedure can be made freely to be acted.For example, in cut-out Fig. 2
The contact of reduction gearing 312 and fixed gear 313.Even if the refrigerating-chamber door 15 not to be noted opened as a result, and touch therewith,
It can prevent injury etc. due to refrigerating-chamber door 15 is acted.In addition, capableing of the distance detection dress of refrigerating-chamber door 15 dominated by hand
It sets the position other than 32 and closes refrigerating-chamber door 15.
When opening control device 33 is determined as that variation delta is less than or equal to value Δ th in step s 11 (Δ≤Δ th)
The length T for being considered as the constant time to direct capacitance magnitude is measured, and will measure the length of the time and stipulated time of gained
Degree Tth is compared (S15).Herein, the direct capacitance magnitude X gradually notified is stored in advance, to direct capacitance magnitude X's
Deviation, which is in prescribed limit, is considered as the length T of constant time measures, and to measure gained time and it is above-mentioned when
Between length Tth be compared (S15).Tth is for example set as in the stepper motor 311 more shown in Fig. 2 than making driving current
The maximum duration of flowing is short.
In the case where being determined as that the length T of time is less than or equal to Tth (T≤Tth), continues to control and be back to
Step S5.
On the other hand, (the T in the case where being determined as that the length T of time is more than Tth>Tth), it is transferred to step S13, that is,
Terminate the control to aperture, also, in step s 13, illumination control apparatus 35 is sent and extinguishes instruction, lighting device 34 is made to put out
It goes out (S13).After so that lighting device 34 is extinguished, it is back to step S1.
For example, after closing refrigerating-chamber door 15, when user rests against refrigerating-chamber door 15, it is determined as T>Tth and
Finishing control.
Assuming that if control is not finished, driving current continues to flow in the stepper motor 311 of Fig. 2, to break down
Possibility increase.Therefore, in embodiments, in Δ>Finishing control in the case of Δ th, thereby, it is possible to prevent it is above-mentioned this
The generation of kind failure.
In addition, opening control device 33 can be electric to the driving flowed in the motor (stepper motor 311) of opening and closing device 2
Stream is monitored, and the finishing control in the case where driving current is more than defined current value.For example, if to refrigerating-chamber door 15
It is applied with very big power, then driving current is possible to increase, and therefore, finishing control in this case, thus, it is possible to prevent in advance
The only failure of motor.Current value is for example set as lower than the maximum current value flowed in stepper motor 311.
In addition, before starting to the control of aperture, after terminating, lighting device 34 is extinguished, after start-up, is controlled
In the process, lighting device 34 is lighted, therefore, user can know the state of aperture control by lighting device 34.
As above, according to the refrigerator of embodiment, have：Distance detection device 32 is used to obtain and door and user
The corresponding detected value of the distance between hand；And opening control device 33, using opening and closing device 31 to aperture controlled with
