The present invention relates to a system for weighing foods and liquids in blenders or food processors, and more particularly, to an integrated and removable weighing device for measuring the weight of ingredients for a blender, or other mixing device, such as a food processor, which can communicate with a software application on a mobile device or computer.
Blenders and food processors are household appliances commonly used to blend, mix, chop, and otherwise process drinks and/or foods. A conventional blender typically has a container with an opening for receiving the liquid or food to be processed. The container has a blade assembly with blades for processing the content in the container. To operate the blender, the container is mounted on a base having a motor that is configured to drive an impeller. The container is mounted on the base by coupling the blade assembly to the impeller. When the motor is activated, it drives the impeller so as to turn the blades to process the content in the container. Typically, the blender can be operated according to various functions selected by the user.
A critical aspect of preparing food or drink is to correctly process the content according to a prescribed recipe. In following a recipe, however, a problem that commonly occurs is the inaccurate or erroneous weighing of ingredients. The problem is often exacerbated when it is necessary to adjust the ratio of the ingredients in a recipe. For example, it is often necessary to scale up or scale down the proportions of ingredients or adjust the proportions if a mistake is made in adding too much of a certain ingredient. Accordingly, there is a need for a system to facilitate the accurate measurement of ingredients for processing in blenders or food processors.
Further, it is common nowadays to use mobile devices, such as smartphones or tablets, to pull a recipe from the Internet. There are often various iterations of a particular recipe based on feedback from different users. Accordingly, there is a need for a system to facilitate the accurate measurement of ingredients for executing a recipe that can interactive with mobile devices.
The present invention is a system for processing comestible content, where comestible content includes both solid and liquid substances. The system comprises a processing device (such as a blender or food processor), a weighing device (such as an electronic scale), and a mobile device (such as a smartphone or tablet), or a laptop or other computing device.
The processing device is generally comprised of a motor base and a container assembly. The base has a motor for driving an impeller (also referred to as motor drive coupling). The container assembly is generally comprised of a container body and a blade assembly. The container body has an open end for receiving the comestible content to be processed. The blade assembly is comprised of a blade mechanism (for blending, mixing, chopping, or otherwise processing the comestible content) and a blade holder. The blade assembly can be integrally affixed or removably affixed to the container body. The processing device is operated by mounting the container assembly on the base by coupling the blade assembly with the impeller and turning on the motor.
One embodiment of the weighing device is an electronic scale having load cells and associated electronics, including a means for wireless communication with a mobile device. The weighing device is adapted to fit on the base and under the container assembly for weighing the comestible content in the container assembly. The weighing device is also removable such that it can be used as a portable scale to weigh the comestible content when the container assembly is not mounted on the base. Alternatively, the weighing device can also be integrated in the base.
For the weighing device to fit between the base and the container assembly without interfering with the coupling between the impeller and the blade assembly, the weighing device is preferably donut-shaped so that the blade assembly can couple with the impeller through the hollow space at the center of the weighing device. The weighing device can be powered by an internal battery or plugged into an external power source, such as the base or a separate charging station.
The weighing device can wirelessly communicate with the mobile device so as to communicate information relating to the weighing of the comestible content to the mobile device. In this way, the user can adjust the weight of the comestible content based on feedback from the mobile device.
In an embodiment of the present invention, an electronic weighing device is configured to enable blenders or food processors to work with recipe applications on mobile devices, tablets, laptops or computers to prepare drinks or foods according to a recipe. The weighing device is configured to weigh the ingredients that are to be processed according to the recipe and transmit the weight information to a mobile device. For example, the weighing device enables a user to follow and complete a drink recipe using a mobile phone application by providing the application with real-time weight information about the ingredients being used in the recipe. Further, the weighing device is capable of attaching to existing blending devices or new blending devices specially designed to accommodate it. The weighing device can also be integrated into the blending devices.
Referring generally to
The comestible processing device (10) is comprised of base (20) and a container assembly (30). The base (20) has a motor (not shown) for driving an impeller (22) shown in

In another embodiment of the invention, the weighing device (50) can also be used with processors (10) specially designed to accommodate it. Referring to
Referring to
The weighing device (50) can be powered by various means to suit the foregoing embodiments. In one embodiment, the weighing device (50) will use traditional alkaline batteries or rechargeable batteries enclosed in the casing (52) for use with existing processors (10). Alternatively, the weighing device (50) can have plugs (63) for plugging into the base (20) for use with processors that have receptors (27, 29).
Referring to
In all the foregoing embodiments, the weighing device (50) measures weight of comestible content X and then transmits the weight information wirelessly to a mobile device (70) for various calculations and visual display of information necessary to accurately complete a recipe.
The weighing device (50) and the container body (32) may also contain sensor elements such as magnetic sensors so that the weighing device (50) can automatically detect the type of container body (32) by detecting the weight of the container body (32).
In operation, the weighing device (50) is placed in a base (20) and turned on for use. In an embodiment, an LED light comes on to indicate the weighing device (50) is turned on and ready to pair with a mobile device (70). Following an initial pairing process, the device will automatically pair with a mobile application when the application is opened and Bluetooth connection is active on the mobile device (70). Upon activation, the user will place the container body (32) (open end (36) up) on the weighing device (50). The recipe application will automatically tare the weight of the container body (32) and communicate that the system is ready for the first ingredient to be added to the container body (32). The system can utilize all the functionality and features of any weight-based recipe application.
For additional interactions between the weighing device (50) and the recipe application and the features of the recipe application, U.S. Pat. No. 8,829,365 of Wallace et al., entitled “System and Method for Maintaining Receipt Ratios When Measuring Ingredients for Culinary Combinations,” is incorporated herein by reference.
Once all the ingredients for the recipe are added, the container body (32) can be removed from the weighing device (50) and the blade holder (42) is attached for blending. At this point the user can decide to deactivate the weighing device (50) or leave it on for additional or repeated use. Once the blade holder (42) is attached to the container body (32), the user will place the container body (32) and blade holder assembly (38) into the base (20) and begin processing. After use, the user can either store the weighing device (50) in the blender or remove it for cleaning or other use. When cleaning the device (50), the user can wash and rinse the devise without concern of liquid ingress.
In an embodiment, the weighing device is connected to a recipe application via a short-range protocol such as Bluetooth or Wi-Fi. In turn, the recipe application is connected to a remote server via a long-range protocol such as the Internet. The recipe application collects the user recipe and weighing information from the weighing device (50) in real time and transmits the information to the remote server.
In another embodiment of the invention, the recipe application can also collect the time, location and personal information of a user using the weight device (50) of the present invention and transmit such information to the remote server. The remote server may collect aggregated customer data and conduct analysis on customer behaviors based on the data relating to the present invention.
In another embodiment of the invention, the remote server can also transmit real time data to the recipe application to provide recommendations of recipes or adjustments of recipe ratios to the users. For example, if the remote server detects that a user is seeking a tequila related recipe, then the remote server can transmit data for a particular tequila recipe and also data of other similar cocktail recipes that may be trending among other users of the system to the recipe application so that they can be recommended and displayed to the user.
As another example, there may be various versions of the recipe based on popular adjustments or variations by other users. When the user is about to add, or has begun to add ingredients, to the container of a blender, the remote server, upon receiving real time data from the recipe application, retrieves data information on other users' variations on the same or similar recipe and provides data of different adjustment ratios for the recipe to the recipe application. If, for example, the original recipe does not contain blueberries, the recipe application may recommend adding a certain amount of blueberries based on the data of other popular versions of the recipe collective from the universe of users. Or, as another example, the recipe application may recommend a reduced amount of sugar to be added based on other users' feedback.
In another embodiment, the operation of the blender or food processor can be automatically adjusted based on the communication and interaction between the weighing device (50) and the recipe application on the computing device (70).
