Description
- The present application claims priority to U.S. Provisional Patent Application Ser. No. 61/097,082 entitled “ENERGY MANAGEMENT OF HOUSEHOLD APPLIANCES”, filed Sep. 15, 2008, the entire disclosure of which is incorporated herein by reference.
- The exemplary embodiments of the present invention generally relate to power usage in appliances. More particularly, the exemplary embodiments relate to providing real-time feedback on the cost of using a refrigerator.
- Users typically do not have any straightforward way of determining energy consumption of an appliance, such as for example, a refrigerator. Energy consumption ties directly to the costs of operating the appliance. It is an aim of many users to minimize energy costs as much as possible.
- Many refrigerators have special features and modes, including energy saving or conservation modes. The energy saving modes can be enabled to cut costs related to running the refrigerator. However, the user usually has no way to determine how much energy is being consumed during normal operation, or when using any one of the special features. It would be advantageous to know how much energy, and correspondingly how much money is being spent, or could be saved, during operation of the refrigerator. Certain behavior patterns with respect to the operation of a refrigerator can also affect the costs associated with operating the refrigerator. The behaviors, such as for example, temperature settings, the number of times the doors are opened, water dispensing and ice making cycles, can all affect energy consumption. It would be advantageous to be able to know how current behavior patterns affects the costs of operating the refrigerator.
- Additionally, in many areas, different rates apply to power usage at different times of the day. For example, in some cities, electricity prices are reduced during certain times of the day to encourage non-peak use. Users are encouraged to run certain appliances during these non-peak time periods. However, it may not always be evident when the periods are or what the associated costs/savings may be. It would be advantageous to be able to easily identify power rates and other factors that impact the power rates.
- Many of the environmental benefits of new appliances, such as refrigerators, can be difficult for the consumer to understand. Presently, potential energy usage and cost information is presented via a yellow Department of Energy (“DOE”) tag that affixed to the appliance. However, during actual use, these energy savings may or not be realized, and there is no way for the consumer to determine if the appliance is being used as efficiently as possible and what the actual cost of operating the appliance is. Thus, it would be advantageous to be able to easily determine and identify energy consumption costs as well as energy saving potential related to usage behavior patterns of an appliance, such as a refrigerator.
- As described herein, the exemplary embodiments overcome one or more of the above or other disadvantages known in the art.
- One aspect of the exemplary embodiments relates to an appliance. The appliance includes a display unit for an appliance and a control unit coupled to the display unit. The control unit is configured to detect at least one current operating parameter associated with use of the appliance, calculate energy usage and energy costs associated with the at least one current operating parameter, and present current energy usage and cost information on the display unit.
- Another aspect of the exemplary embodiments relates to a control system for an appliance. The control system includes an information receiving unit configured to receive operational data related to use of the appliance, a computing device configured to calculate a current energy usage based on the operational data, and a display for presented the calculated current energy usage.
- A further aspect of the exemplary embodiments relates to a method for calculating current energy consumption and costs. The method includes collecting operational usage data from an appliance. An energy cost rate for operation of the appliance is determined. The current cost to operate the appliance is calculated based on the operational usage data and the energy cost rate, and presented to the user.
- These and other aspects and advantages of the exemplary embodiments will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims.

A more comprehensive list is set forth in Table 1 herein. Generally, a refrigerator will also include one or more energy saving operating modes that can be utilized. The real-time display system of the disclosed embodiments will provide the user with information related to the real-time cost of operating the refrigerator. Information related to energy saving features of the refrigerator that can be used in the current operating environment can be presented as well.

For example, if the appliance is a dishwasher, the data could include the length of the wash cycle, the temperature of the water, the drying temperature and time and the amount of water used. This data is then used to provide the user with real-time feedback on the operational costs, as well as, in some cases, energy saving recommendations. In one embodiment, theinformation receiving unit 204 includes sensors and/or detectors (not shown) that are used to detect the usage data and transmit the usage data to theinformation receiving unit 204. - In one embodiment, the user can configure the

Certain parameters can also be manually entered into thecontrol unit 200 via, for example, theinput unit 208, which in one embodiment may also be part of thedisplay unit 210, as illustrated in the example ofFIG. 1 . This can also allow the user to forecast expected operational costs under specific operational parameters. For example, if the user desires to obtain potential energy expense data under certain operational conditions, such as pre-determined temperature or run cycles, the conditions can be specified by the user and transmitted to theinformation receiving unit 204. The cost associated with the pre-specified particulars can then be determined and presented. This allows the user to predict what the operating costs for the refrigerator will be under pre-determined operating conditions. - The
information receiving unit 204 is also configured to detect or receive data related to the power costs, such as the cost per kilowatt hour of power.

input unit 208 is configured to allow a user to manually enter data into thesystem 200. For example, as noted above, different operating parameters can be manually set. Also, cost data can be manually entered. Theinput unit 208, which can also be integral to thedisplay unit 210, provides for the entry of data and information, as well as the selection and activation of different functions. The information and data received by theinput unit 208 can be stored in thestorage unit 206. - The
microcomputer 202 is configured to receive the operational data and power cost information from theinformation receiving unit 204 and/or theinput unit 208. The information and data can be received directly from theinformation receiving unit 204 orinput unit 208, or accessed from thestorage unit 206. Themicrocomputer 202 will process the information and calculate the real-time cost of operating the refrigerator. This data will then be provided to thedisplay unit 210 for presentation to the user. In one embodiment, themicrocomputer 202 can comprise the same computing device that controls the general operations of the refrigerator, or be separately provided.
