As shown in Fig. 2 main part 1 has cooler room 20.Have in the cooler room 20 of refrigerator 100：As evaporation Device plays cooler 35, refrigerator internal fan 21 and the MOD 22 of function.In addition, as shown in figure 3, refrigerator 100 has：Pressure The compressor 31 of contraction cryogen, as condenser play function radiator 32, to radiator 32 blow radiator fan 32a, The capillary 34 for adjusting the magnetic valve 33 of the flow of refrigerant and being depressurized to refrigerant.That is, refrigerator 100, which will have, to press Contracting machine 31, radiator 32, magnetic valve 33, capillary 34 and cooler 35 are connected with refrigerant piping, so that cold for each room But the kind of refrigeration cycle of refrigerant circulation.

In addition, refrigerator 100 (is not schemed with being made up of thermistor and detect the temperature sensor of the temperature of each room for example Show).Other refrigerator 100 has control device 40, and the control device 40 is arranged at the top at the back side of main part 1, each to control The action of kind actuator.

Refrigerator internal fan 21 blows each room of the cold air after being cooled down from cooler 35 into refrigerator.MOD 22 is set In the wind path towards each room, to each room cool-air feed or cut-out cold air.That is, MOD 22 is to flowing into each room in refrigerator The amount of cold air is adjusted.

Control device 40 controls the action of the multiple electric components of the possessed of refrigerator 100.The refrigerator 100 of present embodiment, There is refrigerator internal fan 21, MOD 22, automatic ice maker 23 and magnetic valve 33 as electric component.More specifically, Control device 40 is by controlling the action of refrigerator internal fan 21, so that the cold air after cooled device 35 is cooled down is blown to each room. In addition, temperature of the control device 40 according to each room detected in temperature sensor, controls the action of MOD 22.That is, If the temperature of room is higher than target temperature, control device 40 acts MOD 22 in a manner of opening wind path, is supplied to room Cold air.In addition, if the temperature of room is cooled to target temperature, control device 40 makes MOD 22 in a manner of closing wind path Action, cut off the cold air supplied to room.

In addition, control device 40 controls magnetic valve 33, the stream of refrigerant is thus adjusted.Here, control device 40 has Power circuit (not shown), and it is preset the current capacity itself allowed, the i.e. current capacity of power circuit.Below will The current capacity of the power circuit of control device 40 is also referred to as " allowable current capacity ".

Magnetic valve 33 is in the refrigeration for being layed in before refrigerator 100, being flowed in the refrigerant piping at side and the back side The flow of agent is adjusted.Magnetic valve 33 includes two-port valve 33a and triple valve 33b.Two-port valve 33a has setting porose multiple Cap, the diameter for being arranged at the hole of each cap are different.Two-port valve 33a is by the flow arrangement cap in refrigerant, thus Adjust the flow of refrigerant.Two pipe arrangements that the outflow side of triple valve 33b refrigerant is different from diameter connect.Triple valve 33b The flow of refrigerant is adjusted by being opened and closed the stream towards two pipe arrangements.

More specifically, as shown in Fig. 4 (a)~Fig. 4 (d), the refrigerant that two-port valve 33a makes to flow into from pipe arrangement A is from pipe arrangement B Outflow.In Fig. 4 (a)~Fig. 4 (d) example, two-port valve 33a has three different caps 331~333 of aperture, and aperture is pressed Reduce according to the order of cap 331, cap 332, cap 333.State 1 shown in Fig. 4 (a) is the state of two-port valve 33a standard-sized sheets.Figure State 2 shown in 4 (b) is the state that two-port valve 33a has cap 331 in the flow arrangement of refrigerant.State 3 shown in Fig. 4 (c) It is the state that two-port valve 33a has cap 332 in the flow arrangement of refrigerant.State 4 shown in Fig. 4 (d) is that two-port valve 33a is making The flow arrangement of cryogen has the state of cap 333.Therefore refrigerant flow according to state 1, state 2, state 3, state 4 it is suitable Sequence reduces.

In addition, as shown in Fig. 5 (a)~Fig. 5 (d), triple valve 33b makes from the refrigerant that pipe arrangement C is flowed into from pipe arrangement D and pipe arrangement At least one party's outflow in E.In Fig. 5 (a)~Fig. 5 (d) example, pipe arrangement D diameter is more than pipe arrangement E diameter.Fig. 5 (a) Shown state 1 is the state of triple valve 33b standard-sized sheets.State 2 shown in Fig. 5 (b) is that triple valve 33b is closed towards pipe arrangement E Stream state.State 3 shown in Fig. 5 (c) is the state that triple valve 33b closes the stream towards pipe arrangement D.Fig. 5 (d) institutes The state 4 shown is the state that triple valve 33b closes the stream towards pipe arrangement D and pipe arrangement E both sides.Therefore the flow of refrigerant is pressed Reduce according to the order of state 1, state 2, state 3, state 4.

As shown in fig. 6, refrigerator 100 has：Detect first opening and closing sensor 50a, the inspection of first 2a open and-shut mode Second opening and closing sensor 50b for surveying second 2b open and-shut mode and the image unit for the inner side for being arranged at first 2a 60.First opening and closing sensor 50a and second opening and closing sensor 50b are for example made up of magnetic sensor.First opening and closing passes Sensor 50a and second opening and closing sensor 50b exports the detection information for representing testing result to control device 40.It is more specific and Speech, first opening and closing sensor 50a, when first 2a is opened, beaten to what first 2a of the output expression of control device 40 was opened Open state detection information, when first 2a is closed, represent that the closed mode that first 2a is closed is examined to the output of control device 40 Measurement information.Second opening and closing sensor 50b, when second 2b is opened, represent that second 2b is opened to the output of control device 40 Open mode detection information, when second 2b is closed, the closing shape that second 2b close is represented to the output of control device 40 State detection information.

Image unit 60 possesses including CCD (Charge Coupled Device：Charge coupled cell) or CMOS (Complementary Metal Oxide Semiconductor：CMOS) etc. photographing element video camera (not shown), to being imaged in refrigerator.In the present embodiment, image unit 60 configures in the state of first 2a is closed In the central portion of refrigerating chamber 2, the whole region of refrigerating chamber 2 is imaged.

Fig. 7 is the block diagram of the functional structure for the control device 40 for showing Fig. 2.As shown in fig. 7, control device 40 has： Open and-shut mode determination unit 41, time measurement processing unit 42, imaging control part 43 and storage part 44.The base of open and-shut mode determination unit 41 In the detection information from first opening and closing sensor 50a and second opening and closing sensor 50b output, judge that refrigerating chamber 2 is to be in The state of opening is in the state closed.Here, the state that refrigerating chamber 2 is opened refers in first 2a and second 2b The state that at least one party opens.The state that other refrigerating chamber 2 is closed refers to the shape that first 2a and second 2b both sides closes State.

That is, as long as at least one party in first 2a and second 2b opens, then open and-shut mode determination unit 41 is determined as cold Hide room 2 and be in the state opened.In addition, if first 2a and second 2b both sides closes, then open and-shut mode determination unit 41 It is determined as that refrigerating chamber 2 is in the state closed.The state that refrigerating chamber 2 is opened is also referred to as open mode below, refrigerating chamber 2 is closed The state closed is also referred to as closed mode.Moreover, open and-shut mode determination unit 41 is changed into closed mode in refrigerating chamber 2 from open mode When, export metering command signal to time measurement processing unit 42.In addition, open and-shut mode determination unit 41 measures command signal in output Afterwards, when refrigerating chamber 2 is in open mode, clear command signal is exported to time measurement processing unit 42.

Time measurement processing unit 42 in refrigerating chamber 2 after open mode is changed into closed mode, by closed mode continue when Between measured as the closed mode duration.That is, time measurement processing unit 42 exports according to from open and-shut mode determination unit 41 Metering command signal, begin to shut off the metering of state duration.In addition, time measurement processing unit 42 continues in off position When time reaches shooting stand-by time set in advance, shooting command signal is exported to imaging control part 43.I.e., in off position Before duration reaches shooting stand-by time, in the case that refrigerating chamber 2 is in open mode, time measurement processing unit 42 will close State duration is reset, and after closed mode is turned into again, restarts the metering of closed mode duration.That is, when Between measure processing unit 42 according to the clear command signal exported from open and-shut mode determination unit 41, the closed mode duration is clear Zero.Then, time measurement processing unit 42 starts again at according to the metering command signal exported again from open and-shut mode determination unit 41 The metering of closed mode duration.

Precedence information, the i.e. expression that the action for interrupting electric component is stored with storage part 44 is preferentially electric from which The action of part starts the precedence information interrupted.Electric current value information is stored with storage part 44, the current value information represents： The value and image unit 60 of driving current during each comfortable load maximum of the multiple electric components of the possessed of refrigerator 100 are in load The value of driving current when maximum.In addition, storage part 44 stores the situation for the refrigerating chamber 2 for representing to image in imaging control part 43 Image information.

Imaging control part 43 makes image unit 60 to refrigeration when exporting shooting command signal from time measurement processing unit 42 Room 2 is imaged.Imaging control part 43 has the operating state of the multiple electric components of monitoring and with reference to the electricity in storage part 44 Flow valuve information obtains the function of the i.e. total current value of total current value of multiple electric components and image unit 60.Shooting control Portion 43 processed is when making image unit 60 image refrigerating chamber 2, in the case where total current value exceedes allowable current capacity, interrupts At least one action in multiple electric components.

More specifically, when exporting shooting command signal from time measurement processing unit 42, obtain makes imaging control part 43 Total current value that image unit 60 is assumed when being imaged to refrigerating chamber 2, and judge whether calculated total current value exceedes and hold Perhaps current capacity.Here, the total current value assumed when making image unit 60 image refrigerating chamber 2 is to maintain multiple electric components Operating state come make image unit 60 act in the case of total current value, hereinafter also referred to " during shooting add up to electric current Value ".Moreover, the total current value when being determined as calculated shooting of imaging control part 43 exceedes the situation of allowable current capacity Under, at least one action in multiple electric components is interrupted, in order to avoid total electricity when making the image unit 60 image refrigerating chamber 2 Flow valuve exceedes allowable current capacity.

In addition, imaging control part 43, based on the precedence information in storage part 44, being selected in makes image unit 60 to cold Hide at least one electric component of interrupt action when room 2 images.That is, imaging control part 43 is to reduce from total current value during shooting The mode of the electric current more than difference obtained by allowable current capacity is subtracted, at least one electrical part is selected according to precedence information Part.Moreover, imaging control part 43 interrupts the action at least one electric component selected when acting image unit 60. Then, imaging control part 43 makes the shooting information for the image that expression images in image unit 60 be stored in storage part 44.

Here, control device 40 can be by realizing above-mentioned each function the hardware such as circuit arrangement realize, such as can make For in DSP (Digital Signal Processor：Digital signal processor) etc. microcomputer or CPU (Central Processing Unit：Central processing unit) etc. the software that performs on arithmetic unit realize.In addition, the storage part of control device 40 44 can be by the PROM such as flash memories (Programmable Read Only Memory：Programmable read only memory) or HDD (Hard Disk Drive：Hard disk drive) etc. form.

The table of driving current when table 1 is the load maximum of the possessed electric component of refrigerator 100 of diagrammatic illustration 1.That is, table 1 is that the current value needed for refrigerator internal fan 21, the 33 respective driving of MOD 22, automatic ice maker 23 and magnetic valve is entered Row arranges the table formed.In the case of table 1, the driving of the refrigerator internal fan 21 of refrigerator 100 needs 0.68A electric current, electromagnetism The driving of valve 33 needs 0.53A electric current.In addition, the driving of the automatic ice maker 23 of refrigerator 100 needs 0.64A electric current, electricity The driving of dynamic air door 22 needs 0.14A electric current.

Table 1

Electric component	Current value
		Refrigerator internal fan	0.68A
Magnetic valve	0.53A
		Automatic ice maker	0.64A
MOD	0.14A
		It is total	1.99A

Table 2 is the figure of precedence information possessed by the control device 40 of diagrammatic illustration 7.As shown in table 2, priority is believed Breath form data for example associated with each electric component by the cis-position i.e. interrupt orders for acting priority interruption is formed.It is excellent First order information considers that each electric component brings the influence of the cooling capacity of refrigerator 100 to set under practical service environment, with Exempt from user and feel inconvenience.

Table 2

Interrupt orders	Electric component
		1	Automatic ice maker
2	Magnetic valve
		3	MOD
4	Fan

More specifically, the priority for interrupting automatic ice maker 23 is set as first by precedence information.It is in addition, excellent The priority for interrupting magnetic valve 33 is set to less than the priority for interrupting automatic ice maker 23 by first order information.In addition, The priority for interrupting MOD 22 is set to less than the priority for interrupting magnetic valve 33 by precedence information.In addition, The priority for interrupting refrigerator internal fan 21 is set to less than the priority for interrupting MOD 22 by precedence information.Separately Outside, in the example of table 2, the interrupt orders of magnetic valve 33 are set to second, the interrupt orders of MOD 22 The 3rd is set to, the interrupt orders of refrigerator internal fan 21 are set to the 4th.

The upper automatic ice maker 23 and magnetic valve 33 of interrupt orders is set to, with being blown to cold air Refrigerator internal fan 21 is compared with the MOD 22 of supply condition of control cold air, the influence to the cooling performance of refrigerator 100 compared with It is small.Therefore refrigerator 100 sets interrupt orders as described above, and control device 40 carries out electrical part based on precedence information The interrupt processing of part, thus, it is possible to the situation in practical service environment, avoiding making user's inconvenience.

Fig. 8 is that the current capacity for the permission of control device 40 for showing Fig. 4 (a)~Fig. 4 (d) is set in the case of 2.5 The timing diagram of the operating state of each electric component.Fig. 9 is to represent the electric current appearance that Fig. 4 (a)~Fig. 4 (d) control device 40 allows Amount is set to the timing diagram of the operating state of each electric component in the case of 2.0A.Figure 10 represents Fig. 4 (a)~Fig. 4 (d) The current capacity that control device 40 allows is set to the timing diagram of the operating state of each electric component in the case of 1.5A.Will figure Timing diagram shown in 8~Figure 10 is corresponding with Tables 1 and 2 to be illustrated.

As shown in the example of figure 8, in the case where allowable current capacity is 2.50A, even at refrigerator internal fan 21, electricity Dynamic air door 22, automatic ice maker 23 and magnetic valve 33 are the state all acted, needed for the driving for also having image unit 60 The nargin of current capacity.So, make at the same time each electric component and image unit 60 all in the case of action needed for most In the case that high current value is less than allowable current capacity, add up to current value not over allowable current capacity.Therefore control device 40 when acting image unit 60, the processing that the action without entering to exercise electric component is temporarily interrupted.However, hold to increase Perhaps current capacity, it is necessary to using Large Copacity power circuit as control device 40 electric power generating composition part, it is therefore desirable to expand The product size of control device 40, so as to cost increase.

Therefore, the refrigerator 100 of present embodiment is set to allow for current capacity and is less than maximum current value.For example, holding Perhaps in the case that the example that current capacity is 2.00A is Fig. 9, i.e. moment t at the time of image unit 60 is imaged₄If The action of any electric component is not interrupted, then total current value when image unit 60 images can exceed allowable current capacity.Cause This control device 40 can be moment t at the time of image unit 60 are driven₄Make interrupt orders' highest automatic ice maker 23 Action temporarily interrupt so that total current value is no more than allowable current capacity.Then, in the release of image unit 60 Moment t₅, control device 40 starts again at the action of automatic ice maker 23.

In addition, for example, allowable current capacity be 1.50A example be Figure 10 in the case of, in moment t₄, magnetic valve 33 Action stop, i.e. moment t at the time of image unit 60 is imaged₆, magnetic valve 33 continues to halted state.However, I.e. moment t at the time of image unit 60 is imaged₆, total current value, which exceedes, during shooting allows current value, so if not entering One step interrupts the action of any electric component, then total current value when causing the image unit 60 to be imaged exceedes allowable current Capacity.Therefore control device 40 is in moment t₆, according to precedence information, the action of automatic ice maker 23 is temporarily interrupted, so that Total current value is no more than allowable current capacity.Then, the t at the time of release of image unit 60₇, control device 40 makes The action of automatic ice maker 23 starts again at.

Figure 11 is that the open and-shut mode of Fig. 3 refrigerating chamber 2 is relative with the timing diagram for the action moment for representing image unit 60 The explanation figure answered.Refrigerator 100 is as shown in figure 11, is changed into closed mode from open mode in the door of refrigerating chamber 2, and closed mode is not In the case of persistently imaging stand-by time, do not imaged by image unit 60, and shooting stand-by time is reset.Then, exist Stand-by time is imaged as metering is started again at after closed mode.Therefore according to refrigerator 100, can be frequently opened and closed in door, food Under the more behaviour in service of disengaging, the chance that unwanted image unit 60 acts is reduced.Thus, it is possible to suppress to interrupt image unit The chance of the action of electric component beyond 60, therefore the stability of action can be improved.

On the other hand, refrigerator 100 is as shown in figure 11, turns into closed mode from open mode in the door of refrigerating chamber 2, and close State continue in the case of imaging stand-by time, and image unit 60 performs shooting.Now, refrigerator 100 is based on control device 40 Power circuit current capacity and precedence information, interrupt at least one action in multiple electric components.Therefore root According to refrigerator 100, total current value when image unit 60 acts can be suppressed, it is thus possible to suppress the power supply electricity of control device 40 The current capacity on road, image unit 60 can be made preferentially to act.

Figure 12 is the flow chart for showing the molar behavior related to the shooting processing of Fig. 7 control device 40.Figure 13 is to show Go out the explanation figure of the specific action example of the shooting processing of Fig. 7 control device 40.First, reference picture 12, to control device 40 Illustrated at the time of making image unit 60 to being imaged in refrigerator.

Control device 40 is standby to be in open mode (Figure 12 to refrigerating chamber 2：Step S101/ is no).If refrigerating chamber 2 is in and beaten Open state (Figure 12：Step S101/ is), then control device 40 is standby is changed into closed mode (Figure 12 to refrigerating chamber 2：Step S102/ It is no).

If refrigerating chamber 2 is closed (Figure 12：Step S102/ is), then control device 40 proceeds by closed mode The metering of duration, as long as refrigerating chamber 2 is not at open mode, then it is standby to the closed mode duration reach shooting it is standby Time (Figure 12：Step S103/ is no, and step S104/ is no).Then, the duration reaches shooting to control device 40 in off position (Figure 12 during stand-by time：Step S103/ is), perform shooting processing (Figure 12：Step S105).On the other hand, control device 40 The duration not up to images stand-by time (Figure 12 in off position：Step S103/ is no) and refrigerating chamber 2 be in open mode In the case of (Figure 12：Step S104/ is), return to step S102.

Next, being based on Figure 13, the shooting processing to control device 40 illustrates.First, control device 40, which is obtained, takes the photograph Add up to current value during picture, and judge whether total current value is more than allowable current capacity (Figure 13 during calculated shooting：Step S201).Control device 40 adds up to current value in shooting more than (Figure 13 in the case of allowable current capacity：Step S201/ is), Based on precedence information, action (Figure 13 of at least one electric component is interrupted：Step S202).

Then, control device 40 makes image unit 60 to being imaged in refrigerator, and makes the shooting letter obtained from image unit 60 Breath is stored in the (Figure 13 of storage part 44：Step S203).Next, control device 40 starts again at the dynamic of the electric component that has stopped Make (Figure 13：Step S204).

On the other hand, (Figure 13 in the case that total current value is below allowable current capacity in shooting of control device 40： Step S201/ is no), do not stop the electric component in action, and make image unit 60 to being imaged in refrigerator.Then, control device 40 make to be stored in (the Figure 13 of storage part 44 from the shooting information that image unit 60 obtains：Step S205).

As described above, the refrigerator 100 of present embodiment total current value in shooting exceedes the feelings of allowable current capacity Under condition, control device 40 interrupts the action of at least one electric component in multiple electric components, afterwards acts image unit 60. Therefore refrigerator 100 can reduce total current value of each electric component at the time of image unit 60 is acted, it is thus possible to Image unit 60 is set preferentially to act.Moreover, refrigerator 100 can by the current capacity for the power circuit for suppressing control device 40, To cut down cost.

That is, refrigerator 100 judges to add up to during shooting when the action of image unit 60 is overlapping with the action of multiple electric components Whether current value exceedes allowable current capacity.And the total current value in shooting of refrigerator 100 exceedes the feelings of allowable current capacity Under condition, the action of at least one electric component in interrupt action, thus, it is possible to obtain photographed images as early as possible.Then refrigerator 100 At the end of shooting is handled, the action of the electric component stopped being started again at, therefore the temporary of electric component can be shortened The action break period.

In addition, in the case that refrigerator 100 temporarily interrupts the action of electric component when image unit 60 acts, with reference to preferential Order information, select the electric component of interrupt action.In the example of table 2, the order of the electric component of interrupt action is：First It is automatic ice maker 23, second is magnetic valve 33, and the 3rd is MOD 22, and the 4th is refrigerator internal fan 21.That is, automatic ice-making Machine 23 is because the current value needed for acting is big and does not interfere with cooling performance, thus the electric component in interrupt action is upper Position.On the other hand, refrigerator internal fan 21 blows cold air into refrigerator, is had a great influence to caused by cooling performance.MOD 22 adjust the supply condition of each room cool-air feed into refrigerator, influence to be inferior to refrigerator internal fan 21 to caused by cold air performance, compared with Greatly.In addition, magnetic valve 33 does not control cold air directly, therefore compared with refrigerator internal fan 21 and MOD 22, to cooling performance Caused by influence it is smaller.That is, refrigerator 100 will influence the interrupt orders of relatively small electric component to caused by cooling performance It is set as upper, the interrupt orders that relatively large electric component is influenceed to caused by cooling performance is set as bottom, because This cooling performance that can suppress refrigerator when image unit 60 acts reduces.

It is the situation for the disengaging for having carried out food at the time of wanting and being imaged with image unit 60 here, in refrigerator 100, The situation of the opening and closing of door is carried out.This point is as the refrigerator of patent document 2, if in order to being touched as camera photography The change for sending out the storage amount of device is detected, and uses irradiation portion and photographic department or weight sensor, then cost increases.With this Relatively, refrigerator 100 acts image unit 60 using the opening and closing of door as trigger, therefore without using for detecting food storage The irradiation portion and photographic department of amount or weight sensor etc., with regard to monitor camera chain in refrigerator can be built, so as to Cut down cost.

Further, since refrigerator 100 is after door opening and closing, it is right in the case that the closed mode of door continue for the defined time Imaged in refrigerator, therefore the unnecessary shooting under the more behaviour in service of frequent shutter door, food disengaging can be suppressed, so as to The chance that electric component action is interrupted can be reduced.That is, refrigerator 100 in refrigerating chamber 2 after open mode is changed into closed mode, Before imaging stand-by time, in the case of at least one opening in first 2a and second 2b, image unit 60 does not enter Row shooting, but shooting stand-by time is reset.Therefore as the situation that door is frequently opened and closed, food disengaging is more, considers to be not required to Under the situation for carrying out the shooting in refrigerator, refrigerator 100 acts image unit 60, is able to maintain that the action of each electric component State.Therefore according to refrigerator 100, it is possible to increase the stability of action, and realize energy-saving.
