USER INTERFACE FOR A PREPARATON APPARATUS

CULINARY

The present invention relates to the general technical field of food preparation apparatus.

More particularly, the present invention relates to a user interface for a food preparation apparatus, to a food preparation apparatus comprising such a user interface as well as to a method of using such a food preparation apparatus.

It is known to provide user interfaces comprising several display devices.

However, these display devices are independent of one another and make it possible to separately perform a specific display function.

In the broader field of home appliances, this concept of dual display exists on many products but is achieved by using a display device with an active matrix and one or more display devices with a passive matrix, generally using LEDs. to backlight pictograms.

A display device with a passive matrix is generally used only to signal information to the user while a display device with an active matrix will be used to signal different information to the user.

Thus, because of their numbers, several simple information such as information on different operating states of the food preparation apparatus, or control information generally requiring only the display of a single word, must be indicated on a display device with an active matrix.

Nevertheless, the display of such information on the screen of the active matrix display device requires the reservation of a surface on this screen to the detriment of the display of other more complex information sometimes requiring the display of a complete sentence or images.

This problem is particularly encountered in a food preparation apparatus where the display of the steps for the realization of a culinary preparation must occupy a prominent place in the screen of the display device.

Also, the present invention aims to solve all or part of the disadvantages mentioned above.

For this purpose, the invention relates to a user interface for a food preparation apparatus comprising:

a first active matrix display device comprising a main screen, said main screen being arranged to display a plurality of information of the first type to inform the user on a culinary preparation to be made, and

a second active matrix display device distinct from the first display device comprising a secondary screen, said secondary screen being arranged to display a plurality of second type information to inform the user of the need to interact with the user interface for advancing steps of carrying out the culinary preparation and where appropriate also for informing the user on a state of operation of the food preparation apparatus

processing means arranged to control the display on the main screen of the first display device and the display on the secondary screen of the second display device,

the main screen of the first display having a first display resolution and the secondary display of the second display having a second display resolution lower than the first display resolution.

Having a second active matrix display device frees space for displaying the information displayed on the main screen of the first active matrix display device, while retaining the possibility of display different other information on the secondary display of the second active matrix display device.

Thus, one of the advantages of this dual display is to make the user interface simple and intuitive with a first display area (main screen) dedicated to displaying complex content relating to the culinary preparation, and a second display area ( secondary screen) dedicated to display content contextual by displaying different texts and if necessary pictograms to inform the user about the need to interact with the user interface and if necessary also to inform the user about the operating status of the food preparation device .

The contextual content displayed on the secondary screen of the second display zone is correlated with the complex content displayed on the main screen of the first display zone, the processing means being arranged to establish this correlation.

In addition, the costs are optimized by decreasing the resolution of the secondary screen that does not require a high resolution to display second type information.

According to one aspect of the invention, the secondary screen of the second display device is disposed in the same field of view of the user as the main screen of the first display device.

This arrangement facilitates the ergonomics of the user interface.

According to one aspect of the invention, the first display device and the second display device are of different technologies.

According to one aspect of the invention, the processing means comprise a single microprocessor or microcontroller.

The use of a single microprocessor or microcontroller to drive the display on both screens makes it easier and more central to coordinate the display on both displays while reducing manufacturing costs.

According to one aspect of the invention, the user interface comprises a first communication bus arranged between the processing means and the first display device, and a second communication bus arranged between the processing means and the second device of the invention. display.

According to one aspect of the invention, the first display device is of the type

TFT.

This type of display device is well suited to display information of the first type, including photos.

According to one aspect of the invention, the second display device is of the OLED type. This type of display device is well suited to display information of the second type, including texts or pictograms.

According to one aspect of the invention, the main screen of the first display device is covered with a capacitive slab.

This arrangement makes it possible to create a touch screen.

According to one aspect of the invention, the secondary screen of the second display device is covered with a capacitive film.

This arrangement makes it possible to create a touch screen and to improve the ergonomics of the user interface that will logically interact with the user interface when displaying second type information by pressing the secondary screen.

According to one aspect of the invention, the plurality of second type information is displayed on the secondary screen of the second display device both in the form of text and pictogram.

This arrangement helps to understand the response to the stimulus sent by the user interface to the user.

The present invention also relates to a food preparation apparatus comprising a user interface as described above.

The present invention also relates to a method of using a food preparation apparatus as described above, comprising the following steps:

from the main screen of the first display device, display information of the first type to inform the user about the culinary preparation to be carried out,

from the secondary screen of the second display device, displaying information of the second type to inform the user of the need to interact with the user interface to advance steps of realization of the cooking preparation,

interacting with the user interface of the food preparation apparatus in response to the second type information displayed on the secondary display of the second display device.

According to one implementation, the interaction with the user interface of the food preparation apparatus is performed by pressing a capacitive film covering the secondary screen of the second display device.

Other advantages and features of the invention will emerge more clearly on reading the detailed description of the invention given by way of non-limiting illustration with reference to the figures which illustrate all or part of a user interface according to the invention.

Figure 1 is a block diagram of a user interface according to the invention.

Figure 2 shows the user interface of a food preparation apparatus according to the invention.

FIG. 3 illustrates a profile view of the user interface of the food preparation apparatus of FIG. 2.

Figure 4 is a partial view of a food preparation apparatus comprising a user interface according to the invention.

As illustrated in FIG. 1, a user interface 1 for a food preparation apparatus 100 according to the invention comprises a first active matrix display device 10 comprising a main screen 11, and a second matrix display device 20. active distinct from the first display device 10 and comprising a secondary screen 21.

By active matrix is meant a matrix comprising pixels controllable independently of one another.

The main screen 11 of the first display device 10 has a first Resol display resolution while the secondary display 21 of the second display device 20 has a second Reso2 display resolution lower than the first resolution of the display. Resol display.

The first display device 10 is, for example, of the TFT type, whose main color screen has a size of 4.3 inches and a first Resol display resolution equal to 480 × 272 pixels.

The second display device 20 is for example of the OLED type, whose monochrome secondary screen 21 has a size of 20 mm × 20 mm and a second reso2 display resolution equal to 128 × 128 pixels.

In addition, the main screen 1 1 and the secondary screen 21 are both arranged in the same field of view of the user, that is to say that from the same position of the eyes the user is able to see both of them screens 1 1, 21.

The main screen 1 1 of the first upper resolution display device 10 is arranged to display a plurality of first type information T1 for the user to inform the user on a cooking preparation, while the screen secondary 21 of the second lower resolution display device 20 is arranged to display a plurality of second type information T2 to inform the user on the need to interact with the user interface 1 to advance steps of realization of the culinary preparation and possibly to also inform the user on an operating state of the food preparation apparatus 100.

Information of the first type T1 aims to inform the user on the culinary preparation that it is possible for him to achieve.

Such food preparation may be listed in a database disposed wholly or partly in the food processor and / or on a remote server.

As illustrated in FIG. 2, such information of the first type T1 may, for example, include photos of a cooking preparation, pictograms representing a level of difficulty of realization, a number of persons for whom the cooking preparation is applied, the preparation time, or the tools to use.

This information is distributed over the entire surface of the main screen 11 of the first display device 10.

In addition, as illustrated in Figure 4, the main screen 1 1 of the first display device 10 may be covered with a capacitive panel 12 making this main screen 1 1 touch.

The user can thus navigate between several displays accessible through several tabs arranged on one side of the main screen 1 1.

The user thus has access to an "ingredients" tab in which he can find a list of ingredients of the culinary preparation and a tab "complements" in which he can find explanatory text on how to prepare the preparation culinary.

Through the capacitive slab 12, it is also conceivable to imagine that the user scrolls the content displayed on the main screen 1 1 or else that it interacts with the user interface 1 to inform the parameters that it intends to use for the realization of the culinary preparation.

Second type information T2 is more contextual information to inform the user on the need to interact with the user interface 1 to advance the steps of carrying out the culinary preparation by the food preparation apparatus or well to inform the user about a state of operation of the food preparation apparatus.

The concept of interaction with the user interface 1 must therefore be interpreted here as a need expressed by the food preparation apparatus 100 that the user performs an action so that the food preparation apparatus can advance in the steps of the method of carrying out the culinary preparation by the food preparation apparatus 100.

Such second type information T2 can for example be in the form of texts and possibly simple pictograms to help understanding what is asked of the user.

Such an interaction may for example consist of displaying the word "VALIDATE" to confirm with the user the parameters entered for the culinary preparation to be performed, or to display the word "REALIZE" to confirm with the user the prior selection of a culinary preparation.

A word, for example "START", may also be displayed to indicate to the user that its interaction with the user interface will cause the start of an electrical power device (not shown) of the food preparation apparatus. 100.

Such an electrical power device arranged to perform a function relating to the operation of the food preparation apparatus 100 and generally comprises a motor for rotating a tool or a tank, and / or a heating member for heating the food introduced into the tank.

This interaction therefore has consequences on the parameterization and / or the operation of the food preparation apparatus 100 and makes it possible to advance in the method of carrying out the culinary preparation by the food preparation apparatus 100. An operating state of the food preparation apparatus 100 can mean that it simply indicates the term "COOKING IN PROGRESS" to indicate to the user that heating means of the food preparation apparatus are in working order. , and that the realization of the culinary preparation advances.

Of course, other words or terms or other interactions or operating states are possible.

The fact that the second display device is active matrix also makes it possible to modify this text, for example in the context of a translation of this text for multilingual use of the food preparation apparatus or in the context of an update of the user interface with new features.

In addition, as illustrated in Figure 3, the secondary screen 21 of the second display device 20 may be covered with a capacitive film 22 making this secondary screen 21 touch.

The user can thus interact with the user interface 1 by pressing directly on the secondary screen 21.

This capacitive film 22 can extend beyond the secondary screen 21 and be used to generate additional control means 24, for example a shortcut key to a home page to be displayed on the main screen 11, or a shortcut key to generate a wireless connection with another device such as a scale or a smartphone.

As illustrated in FIGS. 2 to 4, the main screen 1 1 and the secondary screen 21 as well as the capacitive slab 12 and the capacitive film 22 are covered with a glass plate 2 comprising transparent zones T arranged opposite the screens 1 1, 21 and opaque areas O arranged the rest of the glass plate 2.

In the example shown in FIG. 2, the secondary screen 21 is partly obscured by an opaque zone O of the glass plate 2 so as to define a transparent zone T having a circular contour which gives the illusion that the screen secondary 21 itself has a circular outline.

Pictograms defining locations which the user must press to activate the additional control means are also arranged on the glass plate in areas facing the capacitive film.

The technology used for the capacitive slab 12 and the capacitive film is here of the projected capacitive type.

Finally, the user interface 1 comprises processing means 30 arranged to control the display on the main screen 11 of the first display device 10 and the display on the secondary screen 21 of the second display device 20 .

Of course, the processing means 30 display the second type information T2 on the secondary screen 21 of the second display device 20 in a manner consistent with the first type information T1 displayed on the main screen 1 1 of the first device. display 10.

Thus, if the user informs the parameters that he intends to use for the realization of the culinary preparation from the main screen 1 1 touch then he will be asked to "validate" these parameters by a press on the secondary screen 21 touch.

The display of the second type information T2 on the secondary screen 21 is thus made according to the display of the first type information T1 on the main screen 1 1.

The processing means 30 comprise a single microprocessor or microcontroller thus making it possible to coordinate in a centralized manner the display of the information T1, T2 on the two screens 11, 21.

Such a microcontroller is for example a microcontroller of the RZ series manufactured by Renesas Electronics and having a data bus width of 32 bits.

Each screen January 1, 21 has a dedicated control interface connected to the microcontroller.

The color management by these control interfaces is different because the TFT screen is a color monitor controlled in the ARGB8888 color format, which means that we have 32 bits of data per pixel while the OLED screen is a monochrome screen , which means that only one bit of data per pixel is needed.

For this purpose, the data exchanged between the first display device 10 and the microprocessor 30 are routed via a first 40-wire communication bus 13 and the data exchanged between the second display device 20 and the microprocessor are routed via a second 2-wire communication bus 23.

Although the invention has been described in connection with particular examples of embodiment and application, it is obvious that it is not limited thereto.

In particular, this invention has applications in the related field of coffee machines.

Modifications are possible, especially from the point of view of the arrangement and constitution of the various elements or by substitution of technical equivalents, without departing from the scope of the invention.

It is thus possible that information of second type T2 is also displayed on the main screen 1 1 touch.
