Abstract
Provided is a refrigerator such that the photosynthesis of stored fruit and vegetables can be facilitated by taking into account the states of the stomata of plants using the circadian rhythm of plants. The refrigerator comprising: a storage compartment configured to store food; a light emitting portion capable of radiating visible light to an inside of the storage compartment; and a control portion configured to control operation of the light emitting portion to repeat a predetermined process in a cyclic manner; the light emitting portion comprising: a first light source configured to radiate light having a first wavelength of a visible light region as a central wavelength; and a second light source configured to radiate light having a second wavelength of the visible light region different from the first wavelength as a central wavelength; the control portion configured to control, in the predetermined process, the light emitting portion to perform a first radiation process of causing light to be radiated from both of the first light source and the second light source, to perform a second radiation process of causing light to be radiated only from the first light source after the first radiation process, and to perform a non-radiation process of causing the light including visible light not to be radiated from the light emitting portion after the second radiation process.
Claims (7)
1.[Claim 1] A refrigerator comprising: a storage compartment configured to store food; a light emitting portion capable of radiating visible light to an inside of the storage compartment; and a control portion configured to control operation of the light emitting portion to repeat a predetermined process in a cyclic manner; the light emitting portion comprising: a first light source configured to radiate light having a first wavelength of a visible light region as a central wavelength; and a second light source configured to radiate light having a second wavelength of the visible light region different from the first wavelength as a central wavelength; the control portion configured to control, in the predetermined process, the light emitting portion to perform a first radiation process of causing light to be radiated from both of the first light source and the second light source, to perform a second radiation process of causing light to be radiated only from the first light source after the first radiation process, and to perform a non-radiation process of causing the light including visible light not to be radiated from the light emitting portion after the second radiation process. 37 MARKED-UP COPY
2.[Claim 2] The refrigerator according to claim 1, wherein the first wavelength is between 500 nm and 700 nm including 500 nm and 700 nm.
3.[Claim 3] The refrigerator according to claim 1 or 2, wherein the second wavelength is between 400 nm and 500 nm including 400 nm and 500 nm.
4.[Claim 4] The refrigerator according to any one of claims 1 to 3, wherein the control portion controls the light emitting portion so that the predetermined process is repeated in a cycle of twentyfour hours or shorter.
5.[Claim 5] The refrigerator according to any one of claims 1 to 4, wherein duration time of the non-radiation process is equal to or shorter than a total sum of duration time of the first radiation process and duration time of the second radiation process.
6.[Claim 6] The refrigerator according to any one of claims 1 to 5, wherein the duration time of the first radiation process is equal to or shorter than the duration time of the second radiation process. 38 MARKED-UP COPY
7.[Claim 7] The refrigerator according to any one of claims 1 to 6, further comprising: a door capable of opening and closing the storage compartment; and detection means configured to detect opening and closing of the door; wherein the control portion controls the light emitting portion to perform the non-radiation process in a time slot in which the number of times of opening and closing of the door detected by the detection means per predetermined reference time is equal to or smaller than a predetermined number of times.
