Refrigerators are available in many styles, with the most common styles including both a refrigerator compartment and a freezer compartment, which may be side-by-side or one on top of the other. Controls regulate the temperature in each compartment, but otherwise there is very little control over the precise temperature, humidity, pressure, gas composition, and other variables in each respective compartment. Thus, within each refrigerator or freezer compartment, the conditions are substantially uniform throughout the compartment.
While refrigerator compartments generally do a good job of preserving food items for a short period of time, different foods, beverages, and non-food items require different conditions for maximum preservation. Storage techniques of food in the compartment can also affect the shelf life of the food item. Generally, food preservation in the refrigerator or freezer compartments is limited to a shorter time than is desired by many consumers. Perishability is typically caused by microbial degradation, enzymatic activities, and chemical reactions which may result in changes in safety, sensory, and nutritional quality of the food.
Additionally, various methods of measuring and dispensing comestible dry goods can be uncleanly and inefficient. Using measuring cups on areas such as a countertop typically will lead to at least some waste of the goods, as spilling leads to an inefficient use of the dry goods. Spillage during metering and dispensing also creates untidiness in the area. Inefficiency and untidiness associated with manual measurement and dispensing of dry goods are both commonly considered unpleasant to a consumer.
One object of the present invention is to provide an appliance with a rear wall section, a first side wall section, a second side wall section, at least one door, a top, and a bottom that define an interior of the appliance. A refrigerator section is typically included within the appliance interior. The refrigerator section may have the same or a smaller volume than the interior of the entire appliance. The door(s) have an exterior surface and an interior surface having a door liner and a cavity. Further included is a module removably engaged with the appliance. Yet further included is a resealable comestible dry goods container having a defined interior volume, an exterior, and a bottom portion wherein the container is removably engaged within the module.
Another object of the present invention is to provide a portable dry goods storage and dispensing unit capable of engaging the interior surface of a door of a refrigeration appliance. Included is a module capable of being engaged and disengaged with an interior surface of a refrigerator door. The module further includes at least one, and more typically a plurality of, resealable comestible dry goods container(s) having a defined interior volume, an exterior, and a bottom portion. The container(s) are removably engaged with the module and include a metering and dispensing mechanism positioned proximate the bottom portion of the container such that the mechanism controls content output amount of dry goods from the container's interior volume. The module is also typically capable of maintaining a storage effecting condition (humidity, temperature, pressure, gas composition, and combinations thereof), within the interior of the module and/or the individual containers. The temperature of the interior volume of the container is independently controlled and the humidity of the container is independently maintained by a humidity controller (i.e., a desiccant, a salt packet, or a heater). The container(s) typically further include a resealable, typically substantially air tight or air tight, removable lid on each of the containers. In one embodiment, the desiccant may be removably engaged to the container interior facing surface of the lid.
A further object of the present invention includes a method for a user to store and dispense comestible dry goods. The method generally involves providing an appliance with a refrigerator section and an appliance door that provides access to the refrigerator section and having an exterior surface and an interior surface, the interior surface having a door liner. The door typically includes a module engaging connector for providing at least electrical power to a module. The module that is removably engaged with the door's interior and sized to fit within the door liner is also utilized in the method. The module also typically contains a utility connector that matingly and operatively connects with the module engaging connector of the appliance to supply at least electrical power to the module. Also provided is a resealable comestible dry goods container (or more than one container) that is removably engaged within the module and typically seated within a bottom portion of the module. The container has an interior volume, an exterior, and a bottom portion. The module, or more typically the container, further includes a metering and/or dispensing mechanism positioned proximate the bottom portion of the container and typically below the dry goods output aperture in the bottom of the container. The mechanism controls content output amount of dry goods from the container's interior volume. The user engages the module with the interior of the door, which typically includes operably connecting the module engaging connector to the module utility connector thereby providing at least electrical power from the refrigerator and to the module. The resealable comestible dry goods container(s) are engaged with the module either before or after the container is filled with a dry good by inserting at least a portion of the container into a receiving port or section of the module. Thereafter, a desired content output amount of dry goods from within the container interior volume can be metered and dispensed out of the container by the user. The amount dispensed is typically a user defined output amount.
Additional objects, features, and advantages of the present invention will become more readily apparent from the following detailed description of the preferred embodiments when taken in conjunction with the drawings wherein like reference numerals refer to corresponding parts in the several views.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the appliance as orientated in
The reference number 10 (
The illustrated appliance 10 is shown with the door 22 hingably attached to the appliance. The door covers at least a portion of the refrigerator section 24 that lies within the appliance interior 26, and as shown, the door is in an opened position. The door has an exterior surface 28 and an interior surface 30, with the interior surface exposed in the opened position. The door liner 32 at least partially covers, but more typically covers all or substantially all of the interior surface 30 of the door 22. An interface between the modules and the appliance door, such as interconnecting tabs and grooves or a magnetic engagement, allows for quick and easy installation docking without the use of tools. Differently sized modules may be accommodated through the use of spacer systems that engage the interior of the door and shorten the lateral distance that the module must traverse to engage the spacer. The spacer, when used, would mimic a smaller mounting distance/door pocket or cavity and similarly have an interface such as a tabular on groove mating or magnetic engagement.
The modular construction and interchangeability of modules minimizes manufacturing costs and allows the module to be original equipment or after-market components retro-fit into appliances, after the initial purchase and installation of the appliance in a consumer's home. This interchangeability provides flexibility and improved food preservation and storage for the consumer, improved choice of modules with opportunity to upgrade or replace without replacing the whole refrigerator based upon lifestyle or life stage changes, and allows the consumer to take advantage of new technology improvements and new features as new modules are designed and developed.
A dry goods dispensing and metering module 36 (
The door 22 may provide the ability to engage a plurality of modules to the appliance.
While a push switch as discussed above may be used, alternative electrical engagements of the module 36 with the door 22 may be used instead of, or in addition to, the push switch. A Reed switch may be provided in the door liner for activation by a magnet imbedded in the side wall of the module so as to complete an electric circuit when the module docks into the door pocket. Contact pads on the liner and on the module that complete the electrical circuit when the module is mounted in the door liner may also be employed.
In addition to being engaged with the door 22 of an appliance 10, the module 36 of the present invention may optionally be engaged with a countertop stand 60 and/or a wall bracket 62. The countertop stand 60 and wall bracket 62 would typically also include a connector (typically a female connector) within a port area protected by a spring-biased port cover. The module typically draws electrical power and optionally other utilities.
When a countertop stand 60 is utilized, as shown in
At least one, but more typically a plurality of resealable, comestible dry goods container(s) 70 having a defined interior volume, an exterior, and a bottom portion are removably engaged with the module 36 for ease of filling and cleaning (the container(s) are typically dishwasher safe) and sized to fit into a standard dishwasher. The container also typically includes a metering and dispensing mechanism 72 positioned proximate the bottom portion of the container, such that the mechanism controls the output amount of the dry goods within the container's interior volume when the dispensing mechanism 72 is actuated by a user of the module. Dispensement may occur at an interior or exterior region of the appliance, regardless of the module position. In the situation where the module is engaged to an interior region of the door or appliance and dispensing occurs at an exterior region of the appliance, an access door or recess may be provided, similar to that of an ice maker output area. To facilitate dispensement in this configuration, an opening in the door or appliance located adjacent the dispensing mechanism 72 allows the dry goods to fall similar to that of ice in an ice maker, via gravitational force. Conceivably, a substantially vertically aligned channel or conduit may be connected to the dispensing mechanism 72, thereby allowing for transport of the falling dry goods to the access door or recess area.
The mechanism's metering device may be adjustable such that it can, based upon user input or selection, dispense a variety of amounts of a given dry good accurately. In another embodiment, individual containers may utilize a specified dispensing mechanism suitable for a given dry good to be dispensed. For example, if dry cereal or other high volume bulk material is stored, the typical serving may be one cup, the container may be metered to only dispense in one cup intervals or a predetermined non-adjustable amount. In this instance a gearing mechanism would not be necessary.
Additionally, the metering mechanism 72 may include a rotatable dispensing member 78 positioned below an aperture in the bottom of the container (
The metering and dispensing mechanism 72 is located proximate the bottom portion of the container, bag, or compartment. A user may input a desired output amount of the comestible dry goods to be dispensed manually (using for example, a rotatable dial) or by interacting with a user-interface display 40. The container may include a handle 44 on the exterior of the container, which in turn rotates a shaft 46 that is connected to the handle at a first end of the shaft. The shaft 46 is coupled to a gear system proximate a second end of the shaft. The gear system in one embodiment converts the rotational motion of the shaft to translational motion of a slide actuator. The slide actuator typically has one or more apertures sized to dispense the dry goods. Rotation of the handle 44, shaft 46, and gear system generates movement of the slide actuator to a position that corresponds to expelling of a user-desired input amount. A specific distance of a turn of the handle may correspond to a particular output amount. For example, a half rotation turn of the handle may correspond to metering and dispensing of one cup of a particular dry good. The type of comestible dry goods stored will vary and the same ratio of turn to output amount will not be uniform. Therefore, established ratios will be provided to a user, thereby allowing for easy conversions of output amounts.
In another embodiment, the gear system converts the rotational motion of the shaft into increased or decreased rotation of the rotating member of specified section volume (see discussion above), from which amounts may be determined.
The metering and dispensing may also be accomplished by including at least one receptacle 112 within a rotatable cylinder 110 spaced proximate the bottom portion of the container (
Another manner in which to meter and dispense the dry or bulk goods is illustrated in
Additionally, metering and dispensing may be accomplished by including a scale that weighs the output amount. The module, with data-stored densities of commonly-stored comestible dry goods, is capable of converting the weight of dispensed goods to volume. Dispensement occurs until the user-desired output amount is met.
The container or the module of the present invention typically further include a dry goods conveyor slide 74 that is rotatable between a position that dispenses dry goods in a direction away from the module for ease of use by the user (
The containers of the storage and dispensing module are also typically resealable such that they form an air-tight or substantially air-tight seal on the container for the comestible dry goods. The container(s) typically have an interior volume, an exterior and a bottom portion. The bottom portion of the containers may include a dispensing mechanism or a dispensing and metering mechanism as discussed above. Alternatively, the dispensing or dispensing and metering systems may be incorporated into the bottom portion of the dry goods module itself. Typically, the containers operably engage with the module (typically by being slotted or placed within one or more sections of the bottom portion of the module). The sections may have a predefined area with generally U-shaped, upwardly facing channels for mating with the bottom edge rim of the containers, which are typically clear plastic. Usually, the containers are not tightly engaged with the module, but rather some small amount of movement or play (generally lateral movement) is desirable. It is presently believed that slight movement of the containers when the door of the appliance engaged with the module is opened and closed provides a deterrent or at least partially prevents caking of dry goods within the container.
The storage and dispensing module may optionally maintain a storage effecting condition within the interior of the container (i.e., humidity, temperature, pressure, gas composition, and combinations thereof), which may be different from that of the atmospheric condition immediately surrounding the module. Typically, the module may maintain one more temperature, humidity, pressure, and/or gas levels. For example, the module may be capable of maintaining the container at a plurality of various temperatures, above, below, or at about ambient temperature. A desiccant 82, a salt or heater may be used to regulate humidity, which may be monitored by a sensor and the output of the sensor may be displayed or communicated to the user. A salt may be any compound formed when the acid hydrogen of an acid is partly or wholly replaced by a metal or a metallic radical, including, but not limited to, alkali metal salts such as sodium chloride. A desiccant disk that adjustably regulates humidity may be removably engaged with the container to treat humidity within the container (
The module is capable of operably associating with a plurality of containers. Additionally, the module may be illuminated independently of the refrigerator section to enhance visibility of the containers engaged with the module, especially when the refrigerator door is open and the module engaged to the interior of the refrigerator door. The user-interface or a switch allows the user to illuminate the module, as needed. The module of the portable unit may also include a sensor that is capable of indicating a user predetermined level of container contents, so that prior to complete depletion of the dry goods material within the container, a user is warned of the low level. Like the storage effecting condition, this information could conceivably be delivered via computer network to a user defined electronic mail box/account or a mobile device such as a cellular telephone or an electronically kept grocery list via, for example, a computer networking device.
The present invention further provides a method for a user to store and dispense comestible dry goods. When in use, a user may engage a dry goods module according to an embodiment of the present invention with an appliance, typically a refrigerator door interior, a wall mounted bracket, or a countertop stand as described earlier. As discussed previously, typically the module is engaged with connectors on both the module and the wall bracket, countertop stand or the appliance such that at least electrical power is supplied to the module. Prior to or after the module is engaged with the appliance or other device, the removable container(s) of the modules are filled with one or more dry goods (each container having a different dry good or a mix of dry goods) and engaged with the bottom portion of the module. Usually this involves inserting the container or containers into a receiving port or location in the bottom portion of the module. Typically the bottom of the container has a perimeter rim that mates with one or more of the channels in the bottom portion of the module to seat the container and facilitate its holding in position. Next, the user can dispense the material. Optionally, when a metering mechanism is used, the user may set the amount of material to be dispensed through a user-interface, which may be a computer controlled interface or a manually controlled interface. Thereafter, the user may dispense the dry goods, which may be done manually by the user moving an actuator such as a handle operably connected to the dispensing mechanism or automatically using an electrical motor to actuate the dispensing mechanism.
The method of storing the dry goods may be enhanced by maintaining a storage effecting condition within the interior of the container. This step involves regulating humidity, temperature, pressure, and/or gas composition, either singularly or in combination. It should be noted that the disclosed method steps may be performed in various orders, not limited to the order presented here unless specifically so indicated.
It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
