Refrigerator comprising odor removal device
The present invention relates to a refrigerator comprising on or more cooler or freezer compartments in which food products are placed, a door enabling access to the compartment, and an odor removal device enabling cleaning the air emanating from the food products to the environment in the compartment and forming odor comprising: an UV light source provided in a housing, a fan, a photocatalytic filter and a plurality of openings provided on the housing, enabling passing the air received from interior of the compartment and delivered into the compartment by the fan, and a control unit operating the odor removal device in subsequent on-off periods according to a predetermined algorithm.
1. A refrigerator comprising:
at least one compartment in which food products are placed,
a door enabling access to the compartment, and
an odor removal device enabling cleaning the air emanating from the food products to the environment in the compartment and forming an odor, wherein the odor removal device comprises:
an UV (ultraviolet) light source provided in a housing,
a fan provided upstream from the UV light source,
a photocatalytic filter provided downstream from the UV light source, and
a plurality of openings provided on the housing, enabling circulating the air received from an interior of the compartment and delivered into the compartment by the fan, wherein the fan faces the plurality of openings and draws the air from the interior of the compartment,
a controller positioned outside of the compartment and configured to operate the odor removal device in subsequent on-off periods, detect whether the door is open or closed, and disable the odor removal device upon opening of the door by turning the UV light source and the fan off.
2. The refrigerator according to claim 1 , further comprising:
a timer detecting durations in which the door is open and the on-off periods of the odor removal device, wherein the controller is further configured to receive data from the timer, and regulate operation of the odor removal device according to the data received from the timer.
3. The refrigerator according to claim 1 , further comprising:
a timer detecting a duration in which the door is open, wherein the controller is further configured to include the duration in which the door is open to an operational period of the odor removal device.
4. The refrigerator according to claim 1 , further comprising:
a gas sensor detecting chemicals emanating from the food products to the environment in the compartment and forming the odor, wherein the controller is further configured to receive signals transmitted by the gas sensor, assess the signals transmitted by the gas sensor, and start the operation of the odor removal device if the detected odor amount is higher than a predetermined limit value.
5. The refrigerator according to claim 1 , further comprising:
an on-off button enabling the operation of the odor removal device to be turned on or off by a user.
