WO 2011/131340 A1 discloses a hob with lighting equipment. The hob has at least one transparent or translucent hob plate. Furthermore, the hob has at least one frame surrounding the hob plate at least partially. A plurality of lighting elements are arranged in the frame, next to a narrow side of the frame. The frame has at least one opening on its inner side so that the hob and / or the environment above the hob can be illuminated out of the frame.

It is the object of the present invention to overcome the disadvantages of the prior art, at least in part, and in particular to provide an improved user experience in the operation and / or monitoring of a household appliance, especially from a greater distance and / or peripheral viewing.

This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.

The object is achieved by a household appliance having at least one screen, at least one luminous area and a control device for controlling the screen and the luminous area, wherein the control device is set up in response to an occurrence of a specific event to a predetermined screen display on at least one screen and to emit a prescribed Lichtabstrahlmuster of at least one luminous area.

This household appliance has the advantage that information about the occurrence of a specific event can already be communicated remotely with the aid of the light emission pattern, in particular from a distance of more than two meters. The light information is particularly perceptible peripherally. Only when needed, the user needs to approach closer to the household appliance to read on the screen analogous to the Lichtabstrahlmuster and possibly more detailed screen or message.

The home appliance may be a large household appliance (eg, oven, hob, washing machine, tumble dryer, dishwasher, refrigerator, freezer, etc., or a combination thereof) or a household small appliance (eg, coffee maker, toaster, etc.). The household appliance may be an electrically operated kitchen appliance.

The screen may be a liquid crystal panel or OLED screen, e.g. a TFT screen. The screen is in particular capable of displaying alphanumeric characters as a screen display, possibly also of symbols, etc. The screen is in particular a picture-like screen, but may also be a segment display.

A luminous area can be understood in particular to be a light-emitting area, in particular a surface area, of the domestic appliance.

It is a development that at least one light source is assigned to a luminous area, by means of which the luminous area can be illuminated. The at least one light source represents a component or a component of the household appliance. The luminous area can consequently also be referred to as an "active" luminous area. The lighting areas are therefore not particularly excited by light from the outside to shine, but are automatically illuminated luminous areas. The luminous area radiates a corresponding light emission pattern.

A luminous area may be formed, for example, strip-shaped, annular or free-shaped. For example, a luminous area can be subdivided into a plurality of individually controllable segments or constructed from a plurality of such segments. Depending on the occurrence of an event, only one segment, several segments or all segments can be lit. A luminous area may be formed as a series of - for example, strip-shaped, punctiform, annular, etc. - individually controllable lighting segments. It is thus an embodiment that the control device is adapted to emit light from a local subarea (e.g., including one or more but not all segments) of the luminous area. The subarea may represent a portion of the entire luminous area and then, e.g. also be referred to as a luminous portion.

It is a further development that the at least one light source has one or more LEDs. LEDs are durable, compact and allow a very fast and precise change of their light emission pattern.

It is still a further development that a light emission pattern is a course of a light emission from the light region.

The control device can have a driver for operating the luminous area for driving at least one light source of the luminous area or be connected to such a driver. The controller may also be arranged to control or regulate other functional elements of the domestic appliance (e.g., heating elements, fans, motors, etc.). The control device can be connected to a control panel of the household appliance.

The particular event may include, for example, a user's operation (eg, operating a control, opening and closing a door, putting on cookware, etc.), initiating a function (eg, preheating), setting an operating parameter, reaching or exceeding a predetermined threshold, detecting a warning state, starting or ending a predetermined period of time (eg, a timer), providing location information (eg, information on a shelf level of a furnace), etc.

It is still an embodiment that at least one light emission pattern has or comprises a temporal variation of a brightness. This allows a high signal effect, which can also be perceived particularly well at the periphery. For example, a brightness can be reduced ("the lighting range can be dimmed") or increased. It is a further development that, at least for one event, the temporal variation or change in the brightness, in particular between two brightness values or brightness levels which are greater than zero, can be carried out, ie light with a noticeable or perceptible light intensity is radiated from the luminous area in both brightness values. It is still a further development that, at least for one event, it is possible to vary or vary the brightness over time, in particular between a brightness value or brightness level which is greater than zero and a brightness level of zero (illumination range is switched off). It is a further development that the temporal variation (reduction or increase) of the brightness can be carried out with a perceptible gradient, ie is not performed instantaneously or within a negligibly small period of time. Alternatively, the temporal variation of the brightness can be instantaneously performed.

It is a development that at least one light emission pattern has or is a light emission with a constant brightness.

It is also an embodiment that the control device is adapted to dim the time in response to the occurrence of a predetermined event, for example by reducing and subsequently increasing the brightness. This allows a clear perception of the occurrence of the event for a relatively short period of time, so that advantageously there is a close temporal relationship between the occurrence of the event and the emission of the Lichtabstrahlmusters.

It is a development that an initial brightness level at the beginning of the dimming and a brightness level at the end of the re-increase are the same. It is an alternative development that an initial brightness level at the beginning of the dimming and a brightness level at the termination of the re-increase are different. Thus, the brightness level at the completion of the re-increase may be higher or lower than the initial brightness level.

It is an embodiment that the control device is set up to dim the brightness several times in succession, in particular to dim it periodically. This enables a particularly dynamic signal effect. A multiple periodic dimming can be understood in particular to be a repeated repetition of switching between two brightness levels. The multiple periodic dimming may have a sinusoidal, rectangular or triangular course. If the brightness minimum reached corresponds to a value of zero or close to zero, it is also possible to speak of a "blinking".

It is yet another embodiment that the light emission pattern or the course of the light emission comprises or comprises a temporal variation of a light color, e.g. a color change. This allows a particularly high, intuitively understandable signal to a user, e.g. by using suitable neutral colors (e.g., white), warning colors (e.g., red), etc. It is a further development that the color change is perceptible with a perceivable color gradient, that is, not instantaneously performed. Alternatively, the color change can be performed instantaneously, so the color can be switched suddenly.

It is a further embodiment that the control device is set up to change a light color at the time of a brightness minimum. This allows a user to change a mode of operation or the like in a particularly intuitive manner. are displayed. For example, light of white color can be dimmed, and then light of red color can be re-intensified to the same level of brightness as the white light or to another level of brightness.

It is still another embodiment that the light-emitting pattern has a temporal variation of a shape, e.g. a larger or a smaller partial area of the luminous area radiates light. This allows especially on the distance very well perceptible local evidence. The light emission of a partial area may be e.g. can be achieved by selective activation of only a part of a group of luminous areas or only a part of a plurality of luminous segments of a luminous area.

It is also an embodiment that the household appliance has or is a cooking appliance, such as a stove, in particular an oven, a microwave oven, etc.

The oven may have at least one luminous area arranged on a door handle ("illuminated handle"). Alternatively, the oven can have light areas arranged on lateral pilaster strips ("light strips").

Each lit can have one or more light areas. Under a Lisene can be understood in particular a frontally projecting, vertical wall reinforcement or aperture. However, another home appliance may also be equipped as an oven with a light handle and / or with at least one light curtain, e.g. a refrigerator, a steamer, etc. The light areas of the illuminated panel and / or the illuminated handle may in particular be oblong (for example band-shaped or strip-shaped) light areas.

It is also an embodiment that the household appliance has a hob and the at least one lighting area arranged on lateral edges of the hob, band or strip-shaped lighting areas. Thus, the optical signal effect of the luminous areas can also be applied to hobs. The luminous areas can be arranged below a translucent hob plate and / or in a frame of the hob.

In addition, it is an embodiment that the control device is set up to display a screen display, which indicates information about a certain insertion level of the furnace, on the screen and to emit light from a subarea of the luminous area arranged next to this insertion level. This allows a particularly intuitive visual indication of a shelf level, e.g. as part of a cooking program.

The object is also achieved by a method for operating a household appliance. The method can be designed analogously to the household appliance and has the same advantages.

Thus, in the method of operating a household appliance (which domestic appliance has a screen, at least one lighting area, and at least one control device for controlling the screen and the luminous area), a screen display predetermined thereto may be displayed on the screen in response to an occurrence of a certain event For this purpose, given light emission pattern of at least one luminous area are emitted.

The above-described characteristics, features and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following schematic description of an embodiment which will be described in detail in conjunction with the drawings.

1 shows in a front view a stove;

2 shows in a plan view of a hob of the stove;

3 shows possible light emission patterns; and

4 shows further possible light emission patterns.

1 shows in a front view a stove 1 with a stove 2 and with a cooktop arranged on the upper side thereof 3 , 2 shows the hob 3 in a top view.

The oven 2 has an oven door 4 with a door handle 5 on. Above the oven door 4 there is a control panel 6 with a TFT screen 7 , Side of the oven door 4 and the control panel 6 are front piled pilaster strips 8th arranged. Along the vertical longitudinal extent of the pilasters 8th These each have a band-like lighting area 9 on. Each of the two illuminated areas 9 are several in series, individually controllable light sources, such as LEDs, assigned (o. Fig.). In particular, a plurality of band-like subregions or luminous sections arranged in series can be used 9a to 9d be controlled independently of each other. The light sections 9a to 9d can therefore also as segments of a respective lateral luminous area 9 be understood. In particular, there are horizontal pairs of luminous sections 9a . 9b . 9c respectively. 9d laterally next to the associated insertion levels of a cooking chamber 16 of the oven 2 , In general, the luminous areas 9 be segmented into any lighting sections. However, also a whole light area can 9 be lit up.

The door handle 5 has a horizontally band-like extending luminous area 10 on, which can also be segmented.

Referring to 2 , indicates the hob 3 a top-side hob plate 11 (Eg glass ceramic), the four cooking rings 12 provides. At a front or front edge of the hob plate 11 There is a screen that serves as a screen 13 , Laterally next to the hobs 12 are each two arranged in series from front to back, band-shaped lighting areas 14 available. Each of the two illuminated areas 14 are several in series, individually controllable light sources, such as LEDs, assigned (o. Fig.). For example, a plurality of ribbon-like, arranged in series subregions or lighting sections 14a and 14b be controlled independently of each other. The light sections 14a to 14b can therefore also as segments of a respective lateral luminous area 14 be understood. As a result, for example, in each case a luminous portion 14a . 14b next to a hob 12 be arranged.

In general, the luminous areas 14 be segmented into any lighting sections. As a result, the advantage is achieved that - for example, in an induction cooktop with inductor array - a length of a light section, eg as shown 14a and 14b , is adaptable to a position and / or a diameter of an attached cookware. However, a whole lighting area can 14 be lit up.

The TFT screen 7 , the ad field 13 , the luminous areas 9 or the light sections 9a to 9d , the lighting area 10 as well as the light areas 14 or the light sections 14a and 14b can by means of a control device 15 be controlled. The control device 15 For example, can also operate the cooking zones 12 and the oven 2 or the cooking chamber 16 control or regulate.

3 shows possible light emission patterns M1 and M2 as a plot of brightness, expressed as light intensity Iv in cd, against a time t in s.

A first light emission pattern M1 is emitted by a luminous segment before a time t1. For example, until the time t1 a household appliance (eg the oven 2 or the hob 3 ) or a component thereof (eg a cooking chamber 16 heating heating element of the furnace 2 or a cooking place 12 of the hob 3 ) to be in operation. At least one suitable Luminous area or luminous section (eg the luminous sections 9a to 9d and / or the light area 10 of the oven 2 and / or the luminous areas 14 or the light sections 14a . 14b of the hob 3 ) by means of the control device 15 constantly lit with full brightness ("100%"). The control device 15 can simultaneously a corresponding display in a screen (eg a cooking space temperature and a remaining time in the TFT screen 7 or a cooking level and a remaining time in the display field 13 ) Show.

Upon the occurrence of an event in the form of a lapse of a timer period at time t1, a second light emitting pattern M2 is radiated. The second light emission pattern M2 comprises that the brightness Iv is dimmed three times in succession to a value of about 25%. The first two times the brightness Iv is increased back to the initial value of 100%, the last time it remains at its minimum value of about 25%. The brightness Iv is varied with a sinusoidal brightness curve, which can also be referred to as "breathing". With the last time the minimum value is reached at time t2, the second light emission pattern M2 changes to a constant brightness of approximately 25%. The control device 15 may simultaneously with the Lichtabstrahlmuster M2 a corresponding display in a screen (eg a text "end of time" and "00:00" in the TFT screen 7 or in the display field 13 ) Show. For example, the sinusoidal, "breathing" brightness curve can take a maximum of ten seconds.

In the event that the light emission patterns M1 and M2 from the hob 3 In particular, they can only be emitted by the luminous area 14a or 14b to be radiated, which is next to a hob 12 is located on which an appropriately operated cookware (not shown) is located. Are several cookware on different hobs 12 , can be from the associated lighting areas 14a or 14b generally simultaneously different light emission patterns are emitted.

In the case where the light emitting patterns M1 and M2 are from the oven door 4 In particular, they can only be emitted from that pair of luminous sections 9a . 9 . 9c or 9d are emitted, in which a belonging to the time course food support has been inserted.

4 shows further possible light emission patterns M3 and M4 as a plot of brightness, expressed as light intensity Iv in cd, against a time t. The light emission patterns M3 and M4 are from the hob 3 radiated.

Before the beginning of the light emission pattern M4, in the context of the light emission pattern M3, when the hob is switched on, it will radiate 3 without attachment of a cookware all four light areas 14a . 14b with white light color w and a brightness Iv of 50%. The control device 15 may simultaneously with the Lichtabstrahlmuster M3 a corresponding display or message in the display panel 13 (eg "hob on" and / or a corresponding icon).

Is used as an event a cookware on one of the hotplates 12 This is done by the hob 2 detected ("pot detection") and thereby activates the radiation of the Lichtabstrahlmusters M4. The control device 15 may simultaneously with the Lichtabstrahlmuster M3 a corresponding display or message in the display panel 13 (eg a cooking level).

At the beginning of the Lichtabstrahlmusters M4 at a time t3 in a variant, all the luminous areas 14a . 14b switched off by gradual, sinusoidal dimming down to a brightness value Iv of 0%. Following reaching a minimum of brightness at a time t4> t3, only that luminous area is illuminated 14a or 14b , which is immediately next to the attached cookware, turned back on and emitted light with gradually increasing brightness of him. The other lighting areas 14a . 14b stay off. As a result, light is only emitted from a local portion corresponding to the lit portion left lit 14a or 14b radiated. In another variant, the other lighting areas 14a . 14b to radiate white light w with a brightness of 50% unchanged, and the light emission pattern M4 will only be on the luminous area 14a or 14b , which is located next to the attached cookware, applied. As a result, the lighting area 14a or 14b , which is located next to the attached cookware, different or even lit, can be a highly visible location indication on an active cooking area 12 are given.

Upon reaching the minimum of the brightness Iv at the time t4, the light color can also change, for example from white to red, so that from the time r on the luminous area 14a or 14b , which is located directly next to the attached cookware, red light t4 is emitted, as indicated by dashed lines. The brightness Iv of the red light r can be increased up to a brightness level of 100%.

Of course, the present invention is not limited to the embodiment shown.

In general, other light emission patterns can also be output:
It is a training that when switching on or waking the stove 2 from its standby state, a brightness of the luminous areas 9 and or 10 radiated white light w can be gradually increased from 0% to 50%. Analog can be when switching on or waking the hob 3 the brightness of the light areas 14 radiated white light w gradually increased from 0% to 50%. For example, the gradual brightness transition can lead from 0% to 10% within one second and to 50% within the next second.

It is still a development that when turning off or transferring the furnace 2 in its standby state, a brightness of that of the luminous areas 9 and or 10 radiated white light w can be gradually dimmed to 0%, in particular from 50%. This can be done analogously for the hob 3 based on the illuminated areas 14 be performed. For example, the gradual brightness transition can change from 50% to 10% within one second and to 0% within the next second.

When the oven is on 2 or hob 3 without a heating operation or similar can the light areas 9 and or 10 or the light areas 14 white light w with a brightness of constant 50%.

With the beginning of a heating of the cooking chamber 16 or a cooking place 12 For example, first white light w can be gradually dimmed from a brightness of 50% to 0% and then red light r can be emitted with a gradual gradient, in particular up to a brightness of 100% (eg similar or the same as in FIG 4 described). The gradients for dimming down and for raising the brightness may be the same or different. In the case of the cooking area 12 just like a light section 14a or 14b next to this cooking place 12 be started up again.

However, the re-start can also be carried out with white light w, in particular when events occur other than the start of heating.

If, for example, operating parameters are changed (for example, a cooking chamber temperature of the cooking chamber 16 or a cooking stage of the cooking area 12 ), a Lichtabstrahlmuster can then be generated, in which a one-time dimming and following start-up of the brightness is performed, eg sinusoidal, in particular back to the initial brightness level, in particular with a brightness minimum greater than 0% (eg of 30%). The initial brightness level can be 100% and, for example, apply to red light r.

When a hazardous condition or potential hazardous condition ("warning condition") occurs, a flashing light emission pattern can be generated. In this case, light (eg red light r) can be instantaneously or immediately dimmed down from its original brightness level (eg of 100%) to a brightness level of 0% and, after a first period of time, again instantaneously raised or switched to the original brightness level. Following this, after a second period of time, the light can be instantly dimmed down to 0% from its original brightness level. In one variant, the light remains off at 0%. In another variant, this switching on and off is performed several times. The first time period may be shorter than the second time duration, longer than the second time duration, or as long as the second time duration. The switching off and on can be done on the stove 2 from the lighting areas 9 and 10 be performed simultaneously, or only for a pair of luminescent sections 9a to 9d adjacent to a danger level triggering shelf level. The switching off and on can be done on the hob 3 from the lighting areas 14 be performed simultaneously, or only for a light section 14a or 14b adjacent to a cooker causing the hazardous condition 12 ,

As an event, for example, a cookware on a hob 12 put, with the hob 12 previously not active, can by means of an associated light section 14a or 14b at this cooking place 12 white light w from a brightness of previously eg 50% after a one-time gradual dimming to 0% gradually increased to a brightness of 100%. Cookware is on a previously active or still (residual) hotplate 12 can set, with the start of the brightness at the new cooking area 12 also the color can be changed, eg on red.

Is an event as a cooking stage at a cooking place 12 set, can by means of an associated light section 14a or 14b at this cooking place 12 Light (for example, white light w from a brightness of previously 100%, for example) after a gradual gradual dimming to 0% gradually increased again. The brightness level can be increased to a brightness dependent on the selected cooking level, eg to 50% for a cooking level between 1 and 5 and to 100% for a higher cooking level, for example between 6 and P. When the brightness is raised, the color can also be changed be red, for example.

Used as the event of a cookware from a first cooker 12 on a second hob 12 changed, can at the first hob 12 the means of the local associated lighting section 14a or 14b radiated light (eg red light r) are gradually dimmed down to 0% and at the second hob 12 by means of the light section associated there 14a or 14b radiated light to the original brightness level at the first hob 12 be ramped up, for example to 50% or 100%.

If a lock key (eg a child safety lock) or a pause key is pressed as the event, the illuminated areas 14 dimmed down as a confirmation to a brightness level greater than 0% and then restarted. The boot-up can be carried out to the original brightness level or to a higher or lower brightness level.

Also, for example, a kettle may have a luminous area, in particular adjacent to a window for controlling a water level, e.g. depending on different water levels different light emission patterns or light patterns can spend. Thus, a warning light-emitting pattern can be radiated with detection of dry running.

Generally, "on", "an", etc. may be taken to mean a singular or a plurality, in particular in the sense of "at least one" or "one or more" etc., unless this is explicitly excluded, e.g. by the expression "exactly one", etc.

Also, a number may include exactly the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
