BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a refrigerating apparatus such as refrigerator, a freezer, a wine cabinet, or a combination thereof and a method of controlling cooling climate of the apparatus and displaying control elements. The refrigerating apparatus has an interactive, ergonomic cooling control system.
2. Description of Related Art
Prior art refrigerating appliances typically include one or more refrigerating or freezer compartments for the storage of fresh and frozen foods. Typically, the temperature settings for the fresh food compartment and the freezer compartment were adjusted by manipulating an electromechanical mechanism such as a dial or a sliding switch. Usually these systems provided no apparent way to determine the actual temperature of the compartments and the temperature settings were often determined by user trial and error.
More recently, electronic controls have offered various control schemes the user including, for example, digitally displaying the temperature of a compartment. However, electronic controls can be confusing and, to a large extent, the setting of temperature of a particular compartment remains a trial and error operation. Also, while some refrigerating appliance have climate zones with fixed humidity for certain types of food, there is lack of appliances that permit the adjustment of the humidity. It should be readily apparent that adding adjustment of humidity to adjustment of temperature across multiple compartments increases the complexity and likelihood for potential user confusion in controlling a refrigerating appliance. Therefore, there is a need for a climate control system in refrigerating appliances that provides the user with an interface that is easy to use and easy to understand while at the same time capable of handling complex temperature and humidity adjustments for multiple compartments.
SUMMARY OF THE INVENTIONThe present invention provides a refrigerating apparatus, such as a refrigerator, freezer, or wine cabinet having two or more climate-controlled compartments. The refrigerating apparatus has a climate control device capable of controlling the climate of the compartments. The control device is electrically connected to an interactive display, wherein the display presents a compartment selection element to a user and, upon selection of a compartment by the user, the display presents a predetermined climate control element corresponding to the selected compartment.
In a preferred embodiment, the interactive display has a climate control activation element. The compartment selection element is not presented until the user activates the climate control activation element. The compartment selection element comprises a plurality of compartment icons corresponding to the climate controlled compartments of the refrigerating appliance. The climate control element may comprise, for example, a temperature control icon or a plurality of food-type icons, representing types of foods capable of being stored in the selected compartment.
The interactive display is preferably a touch-control device such as an LCD touch screen. Preferably, the elements of the display are presented sequentially as the user makes selections. For example, first, upon selection of the climate control activation element, the compartment selection element is displayed; second, upon selection of a compartment, the appropriate climate control element is displayed. It is also preferred that the user's selections be highlighted in some manner such as, for example, a color change of the selected icon within an element.
Upon selection of the desired parameters for a selected compartment, the control device will adjust the cooling climate of the compartment to correspond to the temperature adjustment or the humidity and temperature requirements of the food types intended to be stored in the compartment.
These and other features of the invention will be more fully understood from the following detailed description of the preferred embodiments which should be read in light of the accompanying drawings.
