Abstract

A refrigerator-implemented method for optimizing placement of food items in different compartments of a refrigerator, according to one embodiment, includes: receiving a request to store a first type of food item in the refrigerator, determining, using detection hardware, each type of food item already stored in one or more of the compartments of the refrigerator, comparing a characteristic of the first type of food item with a same type of characteristic for each type of food item already stored in the one or more of the compartments of the refrigerator, selecting a first of the compartments in which to store the first type of food item based at least in part on the comparison, and outputting, using an output device, a recommendation to store the first type of food item in the first compartment. Other systems, methods, and computer program products are described in additional embodiments.

First claim

What is claimed is:

1. A refrigerator-implemented method for optimizing placement of food items in different compartments of a refrigerator, comprising:
receiving, by the refrigerator, a request to store a first type of food item in the refrigerator;
determining, by the refrigerator, using detection hardware, each type of food item already stored in at least three compartments of the refrigerator;
comparing, by the refrigerator, a characteristic of the first type of food item with a same type of characteristic for each type of food item already stored in the at least three compartments of the refrigerator;
selecting, by the refrigerator, a first of the compartments in which to store the first type of food item based at least in part on the comparison, wherein the first compartment has an ambient storage temperature which is closest to a predefined ideal storage temperature associated with the first type of food item;
outputting, by the refrigerator, using an output device, a recommendation to store the first type of food item in the first compartment; and
adjusting, by the refrigerator, an ambient storage temperature in the first compartment to substantially match the predefined ideal storage temperature associated with the first type of food item in response to determining that the first type of food item has been placed in the recommended first compartment, wherein the first compartment is directly adjacent a second one of the compartments, the second one of the compartments having an ambient storage temperature which is closest to the adjusted ambient storage temperature of the first compartment.

2. The refrigerator-implemented method of claim 1 , wherein the detection hardware is selected from the group consisting of: a digital camera, a barcode scanner, and a wireless tag reader.

3. The refrigerator-implemented method of claim 2 , wherein determining, using detection hardware, each type of food item already stored in one or more of the compartments of the refrigerator includes using the digital camera, and image recognition software in combination with an input from the digital camera.

4. The refrigerator-implemented method of claim 1 , wherein the first compartment has an ambient storage temperature which is closest to the predefined ideal storage temperature associated with the first type of food item.

5. The refrigerator-implemented method of claim 1 , wherein each of the compartments are individually controllable by the refrigerator and configured to maintain different respective ambient storage temperatures based on the types of food items therein.

6. The refrigerator-implemented method of claim 1 , wherein the ambient storage temperatures of at least two of the at least three compartments are within a range of 30 and 65 degrees Fahrenheit.

7. The refrigerator-implemented method of claim 1 , wherein the characteristic of the first type of food item is a chemical characteristic of the first type of food item and/or the predefined ideal storage temperature of the first type of food item.

8. The refrigerator-implemented method of claim 1 , wherein selecting the first of the compartments in which to store the first type of food item includes:
identifying the second compartment as having an ambient storage temperature which is second closest to the predefined ideal storage temperature associated with the first type of food item; and
recommending that the food item be placed in the first compartment directly adjacent the second compartment such that a temperature gradient across a boundary between the first and second compartments is minimized.

9. A computer program product for optimizing placement of food items in different compartments of a refrigerator, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal, the program instructions readable and/or executable by a processor to cause the processor to perform a method comprising:
determining, by the processor, an ambient storage temperature in each of at least three of the different compartments of the refrigerator;
evaluating, by the processor, whether the compartments are positioned relative to each other such that a temperature gradient across a boundary of the compartments between each pair of directly adjacent compartments is minimized, wherein the at least three compartments are thermally insulated to maintain different unique ambient storage temperatures therein, wherein each of the at least three compartments is individually controllable and configured to maintain different respective ambient storage temperatures based on types of food items therein;
determining, by the processor, an order in which to rearrange the compartments in response to determining that the compartments are not positioned relative to each other such that a temperature gradient across the boundary of the compartments between each of the pairs of directly adjacent compartments is minimized; and
outputting, by the processor and using an output device, the determined order in which to rearrange the compartments.

10. The computer program product of claim 9 , wherein each of the at least three different compartments maintains a unique ambient temperature, wherein each of the unique ambient temperature within a range of 30 and 65 degrees Fahrenheit.

11. The computer program product of claim 9 , the program instructions readable and/or executable by the processor to cause the processor to perform the method comprising:
adjusting, by the processor, an ambient storage temperature in each of the compartments to substantially match a predefined ideal storage temperature associated with one or more types of food items stored therein in response to determining that the compartments have been rearranged into the determined order.

12. The computer program product of claim 9 , the program instructions readable and/or executable by the processor to cause the processor to perform the method comprising:
receiving, by the processor, a request to store a first type of food item in the refrigerator;
comparing, by the processor, a characteristic of the first type of food item with the ambient storage temperature in each of the different compartments of the refrigerator;
selecting, by the processor, a first of the compartments in which to store the first type of food item based at least in part on the comparison; and
outputting, by the processor and using the output device, a recommendation to store the first type of food item in the first compartment.

13. The computer program product of claim 12 , wherein the first compartment has an ambient storage temperature which is closest to a predefined ideal storage temperature associated with the first type of food item.

14. A refrigerator, comprising:
sensors for determining types of food items in each of a plurality of compartments in the refrigerator;
a controller in communication with the sensors, the controller being configured to:
receive a request to store a first type of food item in the refrigerator;
determine, using detection hardware, each type of food item already stored in at least three of the compartments of the refrigerator, wherein the at least three compartments are thermally insulated to maintain different unique ambient storage temperatures therein;
compare a characteristic of the first type of food item with a same type of characteristic for each type of food item already stored in the one or more of the compartments of the refrigerator; and
select a first of the compartments in which to store the first type
