Description

DESCRIPTION

Cooking equipment

The invention relates to cooking equipment. In particular, the invention relates to a cooking equipment that has a cooking plate composed of several surface areas and a heating equipment with several heating units to heat cooking containers that are positioned on the cooking plate, each unit being associated heating to at least one area of the surface. In order to flexibly use various cooking containers with different dimensions and geometries of the bottom of the container on the cooktop, it is advantageous that each heating unit is associated with at least one area of the surface, so that when heating a container positioned on one or several areas of the surface, one or more heating units covered by the container may be active in each case, which is / are associated with the surface unit (s) on which the container is positioned, that is, they are occupied by the recipient. In this way, not only can a certain kind of container and container size be used on one or more areas of the surface, but rather the same ones are suitable for the most diverse containers.

A detector device of the cooking equipment serves to detect the position of containers on the cooktop and to identify one or more areas of the occupied surface, on which containers are positioned. Thus, each heater unit associated with an area of the occupied surface can be connected to active when a container is detected on the area of the surface associated with it. The detector device can be configured to directly detect and identify an area of the occupied surface and / or to detect and identify it indirectly by means of detection and identification by means of a heating unit, this heating unit being associated with the area of the occupied surface. The detector device is adapted to the heating equipment with its sensor system to detect and identify directly and / or indirectly one or more areas of the occupied surface.

An indicating device of the cooking equipment is used to show the service status of the zone (s) of the occupied surface (s) and / or the associated heating unit (s). From a state of the art not documented in writing, it is known that the indicator has an indicator surface, which corresponds to a reduced cooktop surface. The indicator device is configured to display a container detected by the detector device on the area (s) of the surface occupied by at least one geometric element in a sector of the indicator surface that is associated with the occupied area (s) of the surface of the cooking plate.

In order to make possible an unambiguous and directly identifiable association by the user of a container positioned on the cooktop to one or more areas of the surface, graphic displays can therefore be used, which on an indicating surface have a plurality of geometric elements and with this reproduces, for example faithfully to scale, a container positioned on the cooktop, with which the user detects directly where which container is located. However, it is of course sometimes tedious and not very intuitive for the user to detect which service parameters are set for a certain container occupying one or more areas of the surface, or to modify a set service parameter. WO2009 / 053279 A1 shows a cooking equipment according to the preamble of claim 1.

The invention thus formulates the problem of providing cooking equipment having an improved indicating device. In particular, cooking equipment must be provided in which a user can clearly and intuitively identify service parameters of a container positioned on the cooktop and can clearly associate them with it.

According to the invention, this problem is solved by means of a cooking equipment with the characteristics of claim 1. Advantageous variants and improvements of the invention result from the following sub-claims.

The advantages that can be achieved with the invention consist, in addition to a display of service parameters for a container occupying one or more areas of the surface, in which the user can capture the service parameters at a glance and can unambiguously associate them with the container. The cooking equipment provides the user with information on the status of each burner at a glance.

According to the invention, it is provided that the geometric element is configured as a linear element with a separating line, presenting subsectors on both sides of the separating line and that the indicating device is configured to display a plurality of service parameters of the zone or zones of the surface occupied in the subsectors of the geometric element. In this way the user is guaranteed a clear and unambiguous display of the service parameters and an unambiguous association to a recipient is possible for the user. By configuring the indicating device, a clear and intuitively understandable translation of the actual situation on the cooktop is provided.

Different technologies can be used in the heating equipment, such as halogen radiator heater or induction coil / s and their combinations. The heating equipment may have, for example, full-surface induction cooktops, zone induction / temperature-controlled halogen. The heating unit is preferably a heating coil and can be configured as an indirect heating coil in the form of an induction coil or as a direct heating coil in the form of a heating coil, for example a metal heating coil, or a halogen radiator heater. or a halogen incandescent lamp. The cooking equipment can be any known kind of electric cooker. However, the cooking equipment is preferably an induction electric cooker. Preferably, the cooktop is a full-surface induction panel and the heating units of the heating equipment are configured as a plurality of induction coils, which generate the necessary heat energy and transfer it by electromagnetic induction to a bottom of the container positioned on top. the cooktop.

The sensing device for detecting the position of containers on the cooktop and for identifying one or more areas of the occupied surface, on which or on which containers are positioned, may be constituted to identify a degree of coverage of a heating equipment and / or from a surface area. When a container occupies several areas of the surface, they constitute a cooking surface area. When an area of the surface is only partially occupied by the container, it is considered to be occupied by the container when it is covered to a considerable extent by the container or is appreciably covered in one direction.

The indicating device has an indicating surface, which corresponds to a reduced cooktop surface, but is otherwise preferably made to scale. That is to say, it has a ratio of proportion between length and width like the cooktop, but it is smaller. Preferably, the surface areas of which the cooktop is composed are arranged in rows and columns, that is to say in the form of a matrix. The indicating surface also preferably has areas that are also arranged in columns and rows, that is to say in the form of a matrix, whereby each area of the indicating surface is associated with a respective area of the surface of the cooktop.

According to the invention, the linear element has a transverse line, which runs at an angle to the separating line, thereby defining other subsectors of the linear element. Preferably the transverse line is arranged perpendicularly or essentially perpendicular to the separating line. Furthermore, the separating line and the transverse line are preferably intersected at the respective center and thus form a cross. The center of the transverse line and of the separating line corresponds in its position on the indicating surface in preference to the place of the center of the detected container on the cooktop.

Preferably, the service parameter is chosen from the group consisting of

- serving temperature to be adjusted for a container occupying one or more areas of the surface,

- duration of residual heat from one or more heating units and / or from one or more areas of the surface,

- power step of the residual heat of one or more heating units and / or of one or more areas of the surface,

- temperature of the residual heat of one or more heating units and / or of one or more areas of the surface,

- power step of one or more areas of the surface and / or of a heating unit associated with an occupied area of the surface,

- reinforcement stage (booster) of one or more occupied areas of the surface and / or of a heating unit associated with an occupied area of the surface,

- duration of the residual heat of one or more occupied areas of the surface and / or of a heating unit associated with an occupied area of the surface,

- connected / disconnected status of the power stage,

- on / off status of the operating temperature to be set,

- on / off status of the booster stage,

- connected / disconnected status of a cooking automation and / or

- on / off status of a keeping warm function.

By displaying several of the service parameters in the place representing the container on the display surface, the user gets intuitively clear and comprehensive information about this container.

Preferably, one of the displayed operating parameters is the operating temperature to be set or the power stage and another operating parameter is the duration of the residual heat. In a preferred embodiment, one of the displayed operating parameters is also a power step of the waste heat or the waste heat temperature and another service parameter shown is the duration of the waste heat. One of the displayed operating parameters is preferably the duration of the remaining heating or the duration of the residual heat. It is preferably one of the parameters of service shows the connected / disconnected status of the power stage, when another service parameter displayed is the power stage, the connected / disconnected status of the service temperature to be set, when another service parameter displayed is the service temperature to be adjusted, the on / off state of the booster stage, when another service parameter shown is the booster stage and / or the on / off state of a heat preservation function.

In a preferred embodiment, the longitudinal extent and an orientation of the geometric element depend on a size of the container detected by the sensing device and its orientation on the cooktop. Preferably, the longitudinal extension of the geometric element depends on the geometric dimensions of the container detected by the detector device, in particular on the size of the bottom of the container. Preferably, the length of the separator line and the length of the scaled transverse line correspond to the corresponding extent of the bottom of the container. When the bottom of the container is round, therefore the separating line and the transverse line have the same length. Its length depends on the absolute measure of the diameter of the corresponding containers. Preferably, the orientation of the geometric element depends on the orientation of the container on the cooktop. The indicating device is preferably formed so that when the detected container has an angled orientation on the cooktop, the geometric element is also shown with a corresponding angled orientation. When the container has a round or square container bottom, it is a longitudinal extension of the transverse line in the direction in which it extends preferably equal to a longitudinal extension of the separator line in the direction in which it extends. When the container has an ellipsoidal or rectangular shaped container bottom, but not square, it is a longitudinal extension of the transverse line in the direction in which it extends preferably other than a longitudinal extension of the separating line in the direction in which it extends. that spreads. In a preferred embodiment, the spacer line and the transverse line intersect on the indicator surface at a point corresponding to a center of the bottom of the container positioned on the cooktop.

In a preferred embodiment, the indicating device is configured to modify a type of line of the geometric element as a function of an operating state of the heater unit (s) to heat the detected container and / or the one (s). area / s of the occupied surface / s and / or the presence of the container detected on the surface area (s). The type of line can be for example a solid line, dashed line, dotted line, double dotted line. For example, a solid line may indicate that the detector device has detected a container and that the areas of the surface occupied by the container are active. Furthermore, a broken line may indicate that the detector device has detected a container, but that the areas of the surface occupied by the container are inactive. A double dotted line can indicate that the sensing device has detected a container, but that there is a fault. Alternatively or additionally, various configuration variants can also be used in terms of colors of the geometric element, to show the operating status of the heating unit (s) to heat the detected container and / or the occupied zone or zones of the surface and / or the presence or absence of the detected container on the surface area (s) that it occupies or has occupied. For example, a first color variant signals that the heating unit / s and / or surface area / s are in the connected state and a second color variant indicates that the heating unit / s / s and / or area / s of the surface is / are in the disconnected state.

Preferably, the indicating device is configured to change a color pattern of each displayed service parameter as a function of an adjustability of the service parameter. For example, information about the service parameter is represented with a color semantics in which a first color variant of the service parameter indicates that the focus is on the operation of the cooktop, a second color variant of the parameter A third color variant of the service parameter indicates that a cooktop function can be selected, a fourth color variant of the service parameter indicates that A cooktop function cannot be selected, a fifth color variant of the service parameter indicates that a value can be selected for the cooktop, and a sixth color variant of the service parameter indicates that a value cannot be selected for the cooktop. cooking plate. The service parameter can be represented in the form of one or more letters, numbers and / or symbols.

In a preferred embodiment, the indicating device is constituted as a touchscreen. Based on this, the user is provided with the possibility of direct interaction with the service parameters of each burner.

Preferably, the touch screen is configured so that, when the detector device detects a movement of the container on the cooktop, it moves and / or causes the geometric element to move to at least one other area of the indicating surface that is associated with the area (s). from the surface of the cooktop to which the pan has been moved. The geometric element can therefore migrate on the indicator surface as a function of the displacement of the container on the cooktop. In a preferred embodiment, the cooking equipment is configured to, When the detector device detects a movement of the container on the cooktop, it automatically moves the geometric element to at least one other area of the indicating surface, the other area being associated, of which there is at least one, to the one (s) area / s of the surface occupied by the displaced container after its displacement. In another preferred embodiment, the cooking equipment is configured so that, when the detector device detects a movement of the container on the cooktop, it causes the user to move the geometric element to at least one other area of the indicator surface and / or the user to confirm the displacement of the geometric element.

In a preferred embodiment, the equipment for cooking has a memory, which memorizes the service parameters associated with the geometric element, whereby when the geometric element moves, the service parameters associated with the geometric element are moved with the geometric element.

Preferably the touch screen is configured such that a displayed longitudinal extent and / or orientation of the geometric element can be adjusted. This allows the user to manually correct the geometric element, if necessary. For example, the user can zoom in on the separator line and / or cross line and thus also influence the size of the heated zone in relation to the bottom of the container.

According to the invention, the touch screen is configured such that a displayed operating parameter can be adjusted by touch. For example, the indicating device is configured such that the user, by touching the service parameter, provides an assortment of touch-adjustable parameters such as values or the like. For example, the indicating device has another indicating surface on which the assortment can be provided after the user touches the service parameter.

An exemplary embodiment of the invention is represented in the drawings simply schematically and will be described in more detail below. Shown schematically and not to scale in

figure 1 a plan view on a cooking equipment corresponding to the invention; Figures 2 to 6 respective plan views on the cooking equipment shown in Figure 1 in operation;

Figure 7 an enlarged plan view on an indicating device of the cooking equipment shown in Figure 2;

Figures 8a to 8e respective partial plan views on the indicating devices shown in Figure 7.

Figure 1 shows a plan view of a cooking equipment corresponding to the invention. The cooking equipment 1 includes a cooking plate 2, made up of several areas of the surface 21, simply by way of example 48. The cooking equipment 1 also has a heating equipment 3 with several heating units 31, to heat containers (not shown), which are positioned on the cooktop 2. Each heating unit 31 is associated with an area of the surface 21. The heating units 31 are drawn with hatches and surrounded by a dashed line, because they are not really visible in the eye The plan view is shown, but are hidden by the cooktop 2. The different surface areas 21 are not visible to the user in the plan view either, as the user rather perceives the cooktop 2 visually as a single homogeneous surface. that is, the lines that separate the areas of the surface 21 from each other are imaginary lines, which the user does not see; for this reason they are also represented with a broken line. The cooking equipment 1 also has a detector device 4, to detect the position of containers (not shown) on the cooktop 2 and to identify one or more occupied areas of the surface 21, on which or on which containers are positioned. (not shown). The detector device 4 is also represented in a broken line, because it is not really visible in the plan view shown. The cooking equipment 1 also has an indicating device 6, to show a service status of the occupied zone (s) of the surface 21 and / or of the associated heating unit (s) 31. The indicating device 6 has an indicating surface 61, which in this embodiment corresponds to a surface 211 of the cooktop 2 reduced to scale. That is, the indicating device 6 has the same relationship between the dimensions of length and width as the cooktop 2. The indicating device 6 is further configured to display a container (not shown) detected by the detection device 4 on the one or more occupied areas of the surface 21 by at least one geometric element 62 in at least one sector 611 of the indicator surface 61, which is associated with the occupied area or areas of the surface 21 of the cooktop 2. The individual sectors 611 do not are visible in the plan view to the user, rather the indicating device 6 visually perceives the same as an individual surface, that is to say, the lines that separate the sectors 611 from each other are imaginary lines, which the user does not see and therefore both are represented again with a dashed line. The number of sectors 611 corresponds to the number of areas of the surface 21, a sector 611 being associated with each area of the surface. In the plan view shown in FIG. 1, no area of the surface 21 of the plate is occupied kitchen 2 by a container, so that the indicating device 6 does not show any geometric element.

Figures 2 to 6 show in respective plan views the cooking equipment shown in Figure 1 in service. In service means in this context that one or more areas of the surface 21 of the cooktop 2 are occupied by one or more containers. In Figures 2 to 6, the aforementioned imaginary lines of the indicating device 6 have been dispensed with, as well as the heating units 31, for greater clarity of the whole, while the imaginary lines of the cooktop 2 have been shown to that the areas of the surface 21 are seen, for greater clarity of the whole, as a continuous line.

Figure 2 shows a plan view of the cooking equipment 1 shown in Figure 1, in which the user has placed a container 5 on the cooktop 2, such that it occupies six areas of the surface 21. The Indicator device 6 is configured to show the container 5 detected by the detector device (not shown) on the occupied areas of the surface 21, by means of at least one geometric element 62 in the sectors (not shown) of the indicator surface 61 that are associated to the occupied areas of the surface 21 of the cooktop 2. The geometric element 62 of the indicating device 6 is constituted as a linear element with a separating line 621 and has subsectors 623 on both sides of the separating line 621. The linear element has in addition a transverse line 622, which runs perpendicular to the separator line 621, in the center through the separator line 62, thereby defining other subsectors 623 in the form of four quadrants. In total, by the cross-shaped configuration of the linear element, four subsectors 623 are defined. The indicating device 6 is configured to display a plurality of service parameters (not shown) of the occupied areas of the surface 21 in the subsectors 623 of geometric element 62, which has not been shown here for clarity of the whole, but will be described in Figures 7 and 8a to 8e in more detail.

Figure 3 shows a plan view of the cooking equipment 1 shown in figure 2, in which the user has placed on the cooking plate 2, in addition to the container 5 shown in figure 2, two other containers 5 on other areas of the surface 21 of the cooktop 2, whereby the other container 5, with the bottom of the round container, occupies another four areas of the surface 21 and the other additional container 5 occupies eight other areas of the surface 21. Indicator device 6 is configured to display the containers 5 detected by the detector device (not shown) on the occupied zones of the surface 21 by means of respective geometric elements 62 in zones (not shown) of the indicator surface 61, which are associated with the zones occupied by the surface 21 of the cooktop 2. The three geometric elements 62 are configured as respective linear elements with a separating line 621 and a transverse line 622 disp It is angled with respect to the separating line 621 and they present subsectors 623 on both sides of the separating line 621 and the transverse line 622, so that by means of the cross-shaped configuration of each linear element, four subsectors are defined in each case 623. The indicating device 6 is configured to display a plurality of service parameters (not shown) of the occupied areas of the surface 21 in the subsectors 623 of the geometric element 62, which is not represented here for clarity of the whole. A longitudinal extension and an orientation of the geometric element 62 depends on the size of the container 5 detected by the sensing device (not shown) and its orientation on the cooktop 2, as can be seen by comparing the three geometric elements 62 of the three containers 5. Thus, the geometric element 62 of the container 5, which occupies the eight areas of the surface 21 and which is placed obliquely in plan view, presents another longitudinal extension and orientation different from those of the geometric elements 62 of the two containers 5 that they occupy four and six areas of the surface 21 respectively. In this way, the arrangement of the crosses on the indicator surface 61 represents an image, intuitively recognizable by the distribution of the cross pattern and the configuration of the cross pattern, of the actual location of the containers 5 on the cooktop 2.

Figure 4 shows a plan view of the cooking equipment 1 shown in Figure 3, in which the user has removed the container 5 from the cooktop 2, which has occupied eight areas of the surface 21. The indicating device 6 is configured to modify a type of line of the geometric element 62 depending on the presence of the container 5 detected on the area or areas of the surface 21, such that the container 5 is shown removed from the cooktop 2 in the form of lines discontinuous lines on the indicating device 6. Thus, for example, an indication is displayed that the areas of the surface 21 previously occupied by the container 5, meanwhile removed, may continue to be hot.

Figure 5 shows a plan view on the cooking equipment 1 shown in Figure 4, in which the user has moved to the right and up a container 5 which in the plan view of Figure 3 is located at the right down and occupying four areas of the surface 21, whereby the container 5 occupies other areas of the surface 21 other than in Figure 3. The occupation of the areas of the surface 21 of the container 5 in Figure 3 are represented in figure 4 in dashed line and the displacement is represented by the arrow. The detector device 4 has detected the movement of the container 5 on the cooktop 2 and has moved the geometric element 62 corresponding to that container 5 to other sectors (not shown) of the indicator surface 61, which are associated with the areas of the surface 21 of the cooktop 2 to which the container 5 has moved. The indicating device 6 is configured to modify a type of line of the geometric element 62 as a function of the presence of the container 5 detected on the zone (s) of the surface 21, whereby the container 5 displaced on the cooktop 2 is shown in the form of broken lines on the indicating device 6 in the sectors (not shown) associated with the areas of the surface 21 from which the container has been removed. and in the form of continuous lines on the indicating device 6 in the sectors (not shown) associated with the areas of the surface 21 occupied by the container 5.

Figure 6 shows a plan view on the cooking equipment 1 shown in Figure 5, in which the indicating device 6 no longer shows the container 5 moved on the cooking plate 2 according to Figures 3 and 4 in the sectors ( not shown) associated with the areas of the surface 21 from which the container 5 has been removed.

Figure 7 shows an enlarged plan view on an indicating device of the cooking equipment shown in Figure 2. The geometric element 62 of the indicating device 6 shown in Figure 2 is configured as a linear element with a separating line 621 and a transverse line 622 that runs in the center perpendicular to the separating line 621. The linear element is configured, as well as a cross and has, as four quadrants, subsectors 623 on both sides of the separating line 621 and of the transverse line 622. In total they are defined by means of this cross-shaped configuration of the linear element, four subsectors 623. The indicating device 6 is configured to display in each case a service parameter 63 in each of the four subsectors 623 of the geometric element 62, the service parameter 63 having been represented here simply outlined.

Figures 8a to 8e show respective enlarged plan views of the indicating device shown in Figure 7, with Figures 8a to 8e representing respective possible combinatorial variants in relation to the display of the service parameters of the indicating device shown in Figure 7. Figures 8a to 8e show in each case the geometric element 62 with the separating line 621 and the transverse line 622 that runs perpendicular to the separating line and with the subsectors 623 configured as four quadrants, showing certain parameters in each of the subsectors 623 of service 63. The occupation of the four quadrants 623 with associated service parameters, can be fixedly prescribed, but can also be configured variable, being able to adapt to the preferences of the user. Various variations are described simply by way of example below. In preferred embodiments, the display surface 61 is constituted as a touch-sensitive touch-display. Thus, a user can choose the service parameter chosen by him from a specific container by touch and in a further step carry out the modification as desired by means of an adjustment possibility configured optically and also displayed on the screen.

Figure 8a shows, as displayed service parameters 63, a power stage of the heating units (not shown), which is associated with the areas of the surface 21 (not shown) that are occupied by the container (not shown), in the form of a number and in the form of an on / off state of a heat preservation function in the form of a symbol.
