Description

food processor

The invention relates to a food processor with a mixing vessel and an agitator located in the mixing vessel, the mixing vessel is heatable and the food processor has Zeitvorwahlschalter that enable a time delay with respect to the agitator and / or a heating operation, further a sequence of preparation steps is preprogrammed feasible. Such a food processor is known for example from DE 10 2007 059236 AI. In addition, reference should be made, for example, to EP 757530 Bl, concerning a special preparation method, and EP 1 274 333 Bl, relating to a heating device in such a food processor. The invention is concerned with the task of performing the operation of such a food processor as safe as possible.

A possible solution of the problem is given by the subject matter of claim 1 according to a first inventive concept, wherein in this case is based on the fact that the sequence can only be triggered when a brought about by the user active preselection with respect to the time and / or agitator and / or heating adjustment, as far as a stirring and / or heating operation is provided in the preprogrammed sequence, has been carried out by means of the one or more time preselection switch. The operation of the food processor in automatic Abarbeitungsmodus, ie an automatic operation of the food processor, is only possible if by hand beforehand on the provided for manual operation of the food processor selector switch, especially a rotary selector switch, the time for the heating and / or Agitator operation was posed. This is particularly important if the mentioned processing steps can be changed freely within the scope of an executable recipe by the user by input to a control device such as a computer or a mobile device, as further explained below. A conscious, active intervention by the user is therefore required prior to the automatic operation of the food processor, whereby in particular the time selection switch can advantageously be used to ensure that no "infinity operation" of the kitchen machine takes place. and / or agitator operation of the food processor is, for example, turned off for a maximum period of time of one, two or three hours, for example. This could lead to security problems during operation.

The invention also relates to a food processor with a mixing vessel and an agitator located in the mixing vessel, wherein the mixing vessel is heatable and an automatic processing of preparation steps is feasible, further the food processor via a mobile device such as in particular a mobile phone data are transferable.

In order to increase safety even in such a food processor, in particular during automatic operation, although in principle not limited thereto, the invention proposes, in a further possible solution of the problem, according to the subject matter of claim 2, that the food processor with the mobile device is in radio communication and an event such as a program end is reported to the radio, which message triggers a signal from the mobile device. Such an event may in particular also be the exceeding of a predetermined temperature limit or, for example, a "overcooking" detected by a corresponding sensor on the food processor .Furthermore also, for example, a blockage of the agitator, so that, for example, in a pre-programmed agitator operation, a certain stirring speed will not or not achieved in the required durability.

Furthermore, it is provided that it is also possible to respond to such a message by means of the mobile device. For example, when the machine is completely switched off via radio communication or a specific operation is interrupted or repeated following the notification of such an event.

It is also provided that regardless of such a message, a shutdown or repetition of operations by means of the mobile device by means of a remote control to the kitchen machine is transferable. For example, if, due to certain events, the case occurs that a preparation should be completed later than initially intended. The preprogrammed sequence of preparation steps preferably relates to those recipes in which the ingredients have already been completely introduced into the apparatus (mixing vessel) and which recipes then optionally undergo a process change. "For example, a yeast dough must rest for a certain time after kneading, in order then to Once again, it must be kneaded again or a chocolate mousse must be reheated and stirred after cooling, preferably without the presence of the user. Further features of the invention are described below, also in the description of the figures, often in their preferred assignment to the claim concepts already explained above, but they can also be assigned to only one or more individual features, as described here, in particular already negotiated claims, or be independent or in another overall concept of meaning. It is also possible to combine the measures of the claims already dealt with. In particular, it is preferred that a bi-directional control of the kitchen appliance is feasible. This means that, on the one hand, programs from a mobile device, in particular a mobile telephone, to the kitchen machine can be transferred for processing, for example recipe steps, either step by step or as a "package" for then independent processing in the kitchen machine As described, signals and status information can be transmitted to the mobile device and, depending on predetermined limit values, events such as, in particular, the triggering of a signal or, for example, a camera function of the like can be controlled, for this purpose, however, on the food processor or detached from the food processor These can then be controlled by the mobile device, in the sense that the camera is activated and images of the camera are transmitted to the mobile device, and corresponding recipes can be used in the kitchen nmaschine and / or be stored in the mobile device as text and / or as an image file and also as a video sequence. Here, the images and the video sequence are for the user to illustrate what happens when the recipe is processed in the kitchen. kitchen machine is going on and / or to display the result. In addition, the recipes contain corresponding data which can be transferred to the food processor as control data and transmitted for the execution and processing of a recipe. When depositing the texts, etc. in the food processor, these can be transmitted to the mobile device, for example triggered by a corresponding request from the mobile device, where they are changed and / or checked and / or a selection is made and then correspondingly carried out or processed Recipe to be transferred to the food processor. Technically, this can also manifest itself in the fact that a specific recipe already stored in the kitchen appliance is released for processing.

The recipes can be connected to the mobile device via an Internet connection, a telephone connection, a cable connection (for example Ethernet connection) or in any other way, such as by a USB stick, a memory card or the like, in particular also from sources outside the food processor, be transmitted. Furthermore, recipes can also be exchanged between mobile devices. It can also be a feedback of the kitchen appliance in the sense that each a started, performed or completed processing step is reported to the mobile device. This transmission can each trigger a signal on the mobile device. But it can also be stored only there and then retrieved at the option of the user.

The viscosity of a food to be prepared in the mixing vessel can be detected, for example, via an evaluation of the engine torque (via the current consumption). When exceeding a predetermined viscosity Limit value, for example, in the processing of yeast dough or whipped cream is preferably automatically reduces the speed of the agitator or stopped the agitator. The user can be sent via the preferred bi-directional control a corresponding reference to the mobile device, possibly with suggestions on how the user should act in this case.

In addition, it is also provided that own recipes can be programmed in the food processor and / or in the mobile device. For this purpose, an appropriate software advantageously provides framework conditions, such as the choice of a specific stirring time depending on a provided ingredient or a proposed mixture, wherein these values can then also be changed or supplemented by the user.

The recipes can then be individually adapted via an editing function. The editing function is preferably provided in the mobile device.

Furthermore, it is also preferred that the said software prescribes boundary conditions which, with regard to the input of a specific calorie requirement or time specification or nutritional specification such as the observance of a specific diet, prevention of allergies, nutrition in the case of certain special demands, such as sports, etc. pretend.

A step-by-step guided tour of the recipe creation program to be understood is more preferable.

Also, a voice control, which is already present in many mobile devices such as mobile phones, be abpliziert on the processing and preparation of a recipe. Last but not least, the recipe program can output a required list of ingredients to be procured even after creating a recipe.
