Claims (13)

A storage section for storing vegetables;
A detection unit that detects opening and closing of an opening and closing unit that opens and closes the vegetable compartment provided with the storage unit;
A specific unit for specifying a storage timing in which vegetables are stored in the storage unit;
An acquisition unit that acquires, as determination information, a spectral reflectance of light irradiated into the storage unit from a captured image or a light source of the storage unit;
An operation control unit that operates the acquisition unit at least at the storage timing and the deterioration confirmation timing after the storage timing;
A determination unit that determines deterioration of the vegetable based on the determination information acquired at the storage timing and the determination information acquired at the deterioration confirmation timing;
A refrigerator comprising: a notification unit that performs notification according to a determination result by the determination unit. The operation control unit operates the acquisition unit according to a closing timing at which the opening / closing unit is closed after the opening of the opening / closing unit is detected by the detection unit,
The specific part is:
When the determination information acquired at the closing timing indicates that a new vegetable has been stored in the storage unit, the closing timing is specified as the storing timing of the new vegetable,
The storage timing of the new vegetable is maintained when the information for determination acquired along with opening / closing of the opening / closing portion after the storage timing indicates that the new vegetable is continuously stored in the storage portion. The refrigerator according to claim 1, wherein the storage timing of the new vegetable is discarded when it indicates that the new vegetable is not continuously stored in the storage unit. The refrigerator according to claim 1 or 2, wherein the operation control unit determines a deterioration confirmation timing based on an elapsed time from a timing at which the opening / closing unit is finally closed. The refrigerator according to claim 3, wherein the notification unit performs notification indicating that the vegetable has deteriorated and indicates the elapsed time or the number of days according to the elapsed time. A temperature measuring unit for measuring the temperature of the vegetable room,
The said operation control part determines deterioration confirmation timing based on the time when the temperature change measured by the said temperature measurement part is settled in the range defined by the threshold value. Refrigerator. The operation control unit operates the acquisition unit at a plurality of deterioration confirmation timings,
The determination unit determines the progress of the first deterioration in which the color of the vegetable fades and the progress of the second deterioration in which the vegetable is deteriorated so as not to be eaten. The refrigerator described. The refrigerator according to claim 6, wherein the notification unit performs different notifications when it is determined that the first deterioration has progressed and when it is determined that the second deterioration has progressed. The acquisition unit
An imaging unit that images the inside of the storage unit and outputs the captured image;
A detection unit for detecting an image of vegetables included in the captured image,
The refrigerator according to any one of claims 1 to 7, wherein the determination information is an image of the vegetable. The refrigerator according to claim 8, wherein the determination unit determines deterioration of the vegetable based on a difference in brightness between the image of the vegetable acquired at the storage timing and the image of the vegetable acquired at the deterioration confirmation timing. . The specifying unit, refrigerator according to claim 8 or 9 determines whether based on the position of the vegetables image new shelf vegetables continue to be accommodated. The acquisition unit
A light source for irradiating light into the storage unit;
A measuring unit that measures the spectral reflectance of the light emitted from the light source into the storage unit,
The determination information is the spectral reflectance.
The determination part determines deterioration of vegetables based on the difference between the spectral reflectance acquired at the storage timing and the spectral reflectance acquired at the deterioration confirmation timing. Refrigerator described in 1. The refrigerator according to claim 11, wherein a wavelength of the light is in a range of 500 nm to 600 nm. The refrigerator according to claim 11 or 12, wherein the light source is also used as a light source for promoting photosynthesis in vegetables.
