It is shown in solid in such as Fig. 4 when being uniformly charged appropriate reserve in vegetable container 28, vegetable container 28 Bottom 28a is not bent.But, multiple reserves are filled in present dynasty's vegetable container 28 or reserve is only concentrated into loading vegetables During the central portion of container 28, the bottom 28a of vegetable container 28 is bent and close to electrostatic capacitive downward as shown in phantom in Figure 4 Sensor 80.So, static capacity type sensor 80 detects the bottom 28a of vegetable container 28.The now downside of vegetable container 28 Cool air flow path narrow.Control unit 12 detects the bottom 28a of vegetable container 28 to detect by static capacity type sensor 80 The situation that the bottom 28a of vegetable container 28 bends and makes the cool air flow path of the downside of vegetable container 28 narrow downward.

Control unit 12 is, when detecting in the case that the cool air flow path of downside of vegetable container 28 narrows, is preferably carried The control for the situation that the control of ability in height cooling vegetable compartment 21 and the cool air flow path of the downside of report vegetable container 28 narrow In at least any one.Certain control unit 12 can also carry out the control of this two side.Controlled when these controls are referred to as and detected.It is excellent Control proceeds during static capacity type sensor 80 is continuously detected the bottom 28a of vegetable container 28 when Selected Inspection is surveyed.

As the control for improving the ability in cooling vegetable compartment 21, the control for the speed for for example improving compressor 64 is enumerated System, raising refrigeration control of the rotating speed of Air Blast fan 62 etc..Control unit 12 is carrying out improving the ability in cooling vegetable compartment 21 Control in the case of, any one that can only carry out in such control (for example improves control of the speed of compressor 64 System), multiple such controls can also be carried out.By control unit 12 improve the control of the ability in cooling vegetable compartment 21, Even if the cool air flow path of the downside of vegetable container 28 narrows, it can also be sufficiently cooled in vegetable container 28.

Moreover, the control of situation about narrowing as the cool air flow path of the downside of report vegetable container 28, enumerates and is for example making For reporting mechanism display part 17 known as situation display control, from the loudspeaker 18 as reporting mechanism with Sound etc. plays control of such situation etc.., for example can be by report content in the control shown in display part 17 It with text importing in display, can also light the lamp for being arranged at the part that report content is described.Moreover, from raising one's voice Device 18 is played in the control of sound etc., for example, can play report content with the sound of employment, can also play alarm tone.Control unit 12, in the case where carrying out the control that the cool air flow path of downside of report vegetable container 28 narrows, can only carry out such control In any one (such as by report content with text importing in the control of display), multiple such control can also be carried out.

Moreover, replacing the cool air flow path of the downside of report vegetable container 28 to narrow, it can also report that its reason (is held in vegetables Excessively fill in reserve in device 28 or be concentrated with reserve in a part for vegetable container 28), its countermeasure can also be reported (reduce the reserve in vegetable container 28 or the charging method of reserve should be changed).In a word, as long as making profit by report User recognizes the need for the reserve reduced in vegetable container 28 or needs to change the charging method of reserve.

The report for carrying out the above by control unit 12 is controlled, and the user of refrigerator 10 can be noted that under vegetable container 28 The situation that the cool air flow path of side narrows.Moreover, user reduces pair of the amount of reserve in vegetable container 28 etc. by progress Plan, can correct the bottom 28a of vegetable container 28 flexure, the cool air flow path of the downside of vegetable container 28 is broadened, make vegetables It is sufficiently cooled in container 28.

Additionally, it is preferred that being formed as, electrostatic during vegetable compartment door 27 is opened is detected even in vegetable compartment door sensor 15 The detection state change of capacitance type sensor 80, control unit 12 also proceeds the control before the change.For example, being set to Static capacity type sensor 80 is continuously detected the bottom 28a and control unit 12 of vegetable container 28 and entered before vegetable compartment door 27 is opened Gone detection when control.Now, when vegetable compartment door 27 is opened and after opening then pulls out vegetable container 28 towards outside refrigerator When, vegetable container 28 be drawn out to than static capacity type sensor 80 place in the outer part after, static capacity type sensor 80 The bottom 28a of vegetable container 28 can not be detected.But, the detection state change of such static capacity type sensor 80 and unawareness The flexure that taste the bottom 28a of vegetable container 28 is corrected.Therefore, even if the detection state of such static capacity type sensor 80 Change, control unit 12 also proceeds to control during the detection before the change of detection state during vegetable compartment door 27 is opened.And And, after vegetable compartment door sensor 15 detects the situation that vegetable compartment door 27 is closed, control unit 12 is passed based on electrostatic capacitive The actual detection state of sensor 80 is controlled.

Moreover, working as the bottom that the static capacity type sensor 80 before vegetable compartment door 27 is opened does not detect vegetable container 28 In the case of portion 28a, afterwards, what static capacity type sensor 80 detects during vegetable compartment door 27 is opened, Vegetable container 28 is also not present during the detection on static capacity type sensor 80, therefore vegetable is not due to the reason for its detection The bottom 28a flexures of dish container 28.It is therefore preferable that being formed as, during vegetable compartment door 27 is opened, sensed with electrostatic capacitive Device 80 is identical before detecting article, is controlled during without detection.

As previously discussed, in the refrigerator 10 of present embodiment, it is provided with and is scratched downward in the bottom 28a of vegetable container 28 Bottom 28a noncontacting proximity sensor is detected when bent in a non-contact manner, therefore control unit 12 can detect vegetable container The situation that 28 bottom 28a bends and makes the cool air flow path of the downside of vegetable container 28 narrow downward.Therefore, the energy of control unit 12 Enough abilities improved in cooling vegetable container 28, can report user what the cool air flow path of the downside of vegetable container 28 narrowed Situation, or implementation measure is so that vegetable compartment 21 to be cooled down.

Moreover, in the case of the bottom 28a flexures of vegetable container 28, the size of flexure is held in bottom 28a central portion Easily be formed as maximum.Therefore, the opposed field of the central portion of the bottom 28a with vegetable container 28 in the bottom in vegetable compartment 21 In the case of set noncontacting proximity sensor, bottom 28a flexure can be reliably detected and make the downside of vegetable container 28 The situation that cool air flow path narrows.

Moreover, when it is static capacity type sensor 80 to detect the bottom 28a noncontacting proximity sensor of vegetable container 28, , also can be without setting the ground such as sheet metal to be examined in bottom 28a even if the bottom 28a of vegetable container 28 is synthetic resin system Survey.As long as but above-mentioned detected piece 81 being arranged on into bottom 28a and just can more reliably be detected.As long as here, will be by Detection lug 81 is arranged on just can more reliably be detected as the bottom 28a of the part significantly bent central portion.And And, as long as multiple detected pieces 81 to be arranged on to bottom 28a multiple places, even if the portion beyond bottom 28a central portion Divide in the case of significantly bending, also can reliably be detected.

Moreover, working as the suction inlet for being provided with the bottom at the back side of vegetable container 28 and cold air being sucked towards refrigeration cooling chamber 60 In the case of 36, the flowing of cold air from front to back, therefore detection vegetable container 28 can be formed in the downside of vegetable container 28 Downside the importance of situation that narrows of cool air flow path it is higher.

Moreover, during vegetable compartment door 27 is opened, even if the detection state change of static capacity type sensor 80, as long as Control unit 12 proceeds the control before the change, when vegetable container 28 is by towards when pulling out outside refrigerator, although vegetable container 28 Bottom 28a flexure is not corrected, but can also avoid situations such as control terminates during detection.
