Abstract
A refrigerator includes a storing unit for storing vegetables; a light emitting unit for irradiating light onto the vegetables stored in the storing unit to promote photosynthesis of the vegetables; an input unit for receiving an operation instruction on whether the light emitting unit is to be turned on or off; a timer for detecting a current time to output current time information; and a control unit for controlling the light emitting unit in response to the operation instruction. If the operation instruction requests that the light emitting unit be off, the control unit controls the light emitting unit to be off; and if otherwise, the control unit controls the light emitting unit to be on or off depending on the current time information.
Claims12
A refrigerator comprising:
- a storing unit for storing vegetables;
- a light emitting unit for irradiating light onto the vegetables stored in the storing unit to promote photosynthesis of the vegetables;
- an input unit for receiving an operation instruction on whether the light emitting unit is to be turned on or off;
- a timer for detecting a current time to output current time information;
- and
- a control unit for controlling the light emitting unit in response to the operation instruction,
- wherein, if the operation instruction requests that the light emitting unit be off, the control unit controls the light emitting unit to be off;
- and if otherwise, the control unit controls the light emitting unit to be on or off depending on the current time information, and
- wherein the input unit further receives a current state of the vegetables indicating whether the vegetables are in mature stage or in growth stage, and the control unit adjusts a wavelength of the light emitted from the light emitting unit based on the current state.
A control method of a refrigerator including a storing unit for storing vegetables and a light emitting unit for emitting light onto the vegetables stored in the storing unit to promote photosynthesis of the vegetables, the method comprising the steps of:
- a first step of receiving an operation instruction on whether the light emitting unit is to be on or off;
- a second step of controlling the light emitting unit to be off if the operation instruction requests that the light emitting unit be off, and receiving current time information from a timer if the operation instruction requests that the light emitting unit be on;
- a third step of controlling the light emitting unit to be on or off based on the current time information if the operation instruction requests that the light emitting unit be on, and
- wherein, in the first step, the input unit further receives a current state of the vegetables indicating whether the vegetables are in mature stage or in growth stage;
- and, in the third step, a wavelength of the light emitted from the light emitting unit is adjusted according to the current state.
