Description

Technical area

The present invention relates to a hotplate, preferably a gas hob, according to the preamble of claim 1. Hereinafter, the term cooker is a combination of hotplate and oven referred. The term cooker includes in particular the terms cooktop, hob and hob.

State of the art

Usually, the power state of a cooker is indicated by the position of the rotary switch or rotary knob designed to operate the hob or the oven. It can, as in the pamphlets DE 1 274 307 A . DE 1 846 780 U . DE 75 17 896 U and DE 2 204 557 A discloses the position of the rotary switch are numerically displayed in a display panel. In these known rotary switches, a circular disk with numbers is attached to a switching shaft of a rotary switch arranged in the hearth. Depending on the position of the rotary switch, a certain number is visible in a display field of the rotary switch or in a display field of an otherwise opaque strip of the cooker. Alternatively, the numerical power status indication can also be made by means of a seven-segment display associated with the rotary switch, which represents, for example, the heating power of the hotplate in numbers from zero to nine. However, only the current setting of the rotary switch can be read in these known cooking stations with numerical power status display.

Furthermore, the power state of a cooker can also be displayed by means of power status symbols, for example by means of points or by means of a scale arranged around the rotary handle. Such a performance status marking is for example from the document DE 1 846 780 U known. This power state marker is illuminated from the inside of the cooker. For regulating the hearth power, a position mark arranged on the rotary switch, for example a point arranged on the rotary handle, is aligned with the corresponding power status symbol arranged around the rotary switch. A disadvantage of this known rotary switch, however, is that due to the relatively large distance between the position marker and arranged around the rotary switch power status symbols an accurate reading of the position of the rotary switch and thus an accurate regulation of the rotary switch is difficult.

The publication DE 1 252 782 A1 discloses a shift position indicator whose display panel can be mounted at a location more suitable for observation away from the rotary switch. For this purpose, optical fibers are arranged, the Lichtaustrittsstirnen, strung together form the display panel. These light exit bulbs are arranged so that they are shielded in dependence on the switch position by diaphragms against the light source.

From the publication EP 0 172 576 A2 a cooking station according to the preamble of claim 1 is known. In order to make the optical switching stage display of a stove for the operator easily and clearly recognizable, is in the document EP 0 172 576 A2 discloses to provide a light changing element, which makes the different switching stages indicated by different color or light intensity. The color film layer is rising on the circumference of the light-changing element. When the rotary switch is turned on, there is initially an area under a lamp with a small color film width, so that the display area of the rotary switch only lights up a little bit in color. If the rotary switch is set to a higher switching level, a larger color film area is lost The light and the reflected light on the display area gets an ever stronger and more intense color drawing. Thus, the user can estimate over the intensity of the color signals even at a great distance the instantaneous shift stage setting. The user thus receives an idea of the relative power output via the intensity of the color signals.

From the publication DE 33 45 312 C2 a rotary switch is known, the operating and display member consists of a serving for the position marking of the rotary switch window of the rotary knob grip part and a rotary knob grip part surrounding scale ring part. The window of the rotary switch is illuminated from the inside of the device. For easier recognition; Whether the rotary switch is on or off, the rotary switch a colored translucent panel is mounted, which is arranged in the zero position of the rotary switch in front of the lamp designed to illuminate the window. The aperture thus causes the window of the rotary knob handle part is illuminated in the zero position of this rotary switch colored and attenuated. The disadvantage, however, is that even with this rotary switch, the position marker or the window has a relatively large distance from the Einstellstellierungszeichen the scale ring part, so that a precise regulation of the rotary switch is difficult.

So that a user of a cooker can easily survey all switching stages and at the same time easily recognizes which switching stage is currently switched on, the document discloses DE 75 17 896 U a display device with a light-emitting pane equipped with a different-colored display panel. This translucent disk is arranged between a light source and a scale disk provided with translucent symbols and rotatable by the operating handle. The differently colored translucent display disc clearly differentiates the set value from all numbers. The disadvantage is that the power status symbols are arranged only on the rotary handle and are thus covered by the hand of the user upon actuation of the rotary handle.

From the publication DE 196 51 821 A1 is a rotary switch for a laundry treatment or dishwasher known. This rotary selector has a ring lighting. A diffuser attached to the switch shaft distributes the light evenly over the transparent circular ring of the ring illumination. The diffuser also carries a marker in twelve o'clock position to indicate the detent position "end".

Furthermore, from the document DE 36 02 020 A1 a rotary switch with ring lighting known. The ring illumination is formed by a luminous ring made of transparent material, which is suitably colored, preferably red. On the frustoconical surface of the light ring, the zero position is marked.

Switch devices with an axis, which are located on a cooktop plate, are from the document EP 0 962 707 A2 known.

The publication DE 202 21 565 U1 discloses a cooking station with a light ring arranged around the rotary switch and at least one further light mark which is moved by the rotary switch and which indicates its position. Translucent markings are placed on the control panel around the rotary switch. Behind these markings, a disc with a cutout is arranged in such a way that, depending on the position of the rotary switch, exactly one marking can be illuminated by a light source arranged behind it.

DESCRIPTION OF THE INVENTION: Problem, Solution, Advantages

Based on the disadvantages and inadequacies set out above and in appreciation of the state of the art outlined, the present invention has the object, a cooking point of the type mentioned in such a way that the performance of the hotplate can be more accurately and easily regulated.

This object is achieved by a hotplate with the features specified in claim 1. Advantageous embodiments and expedient developments of the present invention are characterized in the subclaims.

Thus, the present invention is based on the fact that a lighted indicator is located respectively in, in particular below or above and / or directly next to, the area of the power area marking, which is assigned to the current position or orientation of the switch shaft. By means of the illuminated indicator, the current power state of the cooking area, thus accurately displayed. By illuminating the indicator readability is possible even in unfavorable lighting conditions.

The power area marker is formed of translucent areas of a cooktop panel, wherein the areas surrounding the power area marker are non translucent areas of the cooktop panel.

According to the invention, the indicator is at least one color filter which allows only light of at least one color to pass through or the light of at least one color filters out, that is to say causes a color shift of the light passing through the indicator. Thus, by means of the indicator of the current position or orientation of the switch shaft associated region, for example, the current position or orientation of the switch shaft associated power state symbol, be marked in color. In principle, the indicator can color the light in whose beam path it is in any color or even multicolored. The area indicated by the indicator should differ only from the color of the rest of the performance area mark.

The indicator is arranged on the switch shaft such that it is in each case in the beam path of the area of the power range marking assigned by the illumination device to the current position or orientation of the switch shaft emitted light is located. In addition, the indicator is arranged in the beam path of the light emitted from the illumination device to the control knob light. Thus, at least one area of the control knob is marked in the same way as the area of the power area marking assigned to the current position or orientation of the switch shaft.

The areas of the power area marker associated with the positions or orientations of the switch shaft may be marked by power status symbols. Such power status symbols can be, for example, numbers, line markings, dot markers, at least one threshold arrow or gas flames of different sizes. By means of the switch device according to the invention, the indicator is aimed exactly at or directly next to the power state symbol. Thus, a more accurate adjustment of the switch device is possible than with a rotary switch according to the prior art, the position or orientation of which is marked by a arranged on the rotary switch and a distance from the power status symbol point or window.

Advantageously, the indicator is designed to at least partially filter the light emitted by the illumination device and / or at least partially hide it.

According to a particularly preferred embodiment, the indicator is designed to allow only blue light to pass, ie to color the area to which the indicator is aligned in blue. The rest of the power range marking, however, is colorless, for example, illuminated with colorless light. This blue coloration is particularly advantageous when the switch device serves to regulate the power of a cooker, for example a gas cooker. Since food is usually not colored blue, the blue light is still well visible even if the stove is soiled with food.

The indicator is dimensioned to identify only a portion of the power band mark. The narrower the area indicated by the indicator, the more accurately the orientation or position of the switch shaft and thus the setting of the power regulated by the switch shaft are displayed. For example, the indicator may be dimensioned such that it marks or marks approximately a maximum of one fifth or a maximum of one tenth of the power range marking. Alternatively, the indicator can also be designed in the manner of a fan, which is fanned out or pushed together during the movement of the switch shaft.

In this case, the indicator is a trained in their entirety as an indicator surface, for example, designed as an indicator pointer, such as a colored plastic strip.

Alternatively, the indicator may be at least one region of an otherwise completely transparent surface arranged around the switch shaft, for example a disk arranged around the switch shaft.

To protect against damage, the indicator is advantageously arranged between the power area marking and the lighting device in the interior of the cooking area. Alternatively, however, the indicator can also be arranged on the outside of the cooking area above or directly next to the power range marking.

The illumination device is designed to illuminate the entire area of the power area marking. In order to obtain a uniform illumination of the power area marking, according to an advantageous embodiment, at least one diffuser for scattering the light emitted by the lighting device is arranged between the illumination device and the power area marking. The surface of the diffuser is advantageously at least as large as the area of the performance area mark. A diffuser extending over the entire area of the power area marker and disposed about the switch shaft may be fixedly attached to the switch apparatus. Such a diffuser therefore does not need to be moved with it when changing the position or orientation of the switch shaft, because it is anyway in any conceivable position or orientation of the switch shaft in the beam path of the light emitted from the illumination unit for power range marking light.

Furthermore, in order to provide uniform illumination of the surface of the power-range marking, the illumination device can have a plurality of, for example six, illuminants arranged below the power-range marking or around the switch shaft.

The switch device may be configured as a rotary switch, wherein the switch shaft is rotatable about its longitudinal axis for regulating the power of the cooking position. In this case, the indicator is advantageously arranged on the switch shaft such that it rotates during the rotational movement of the switch shaft with this about the longitudinal axis of the switch shaft. The indicator can also be designed in the manner of a fan, which is fanned out or pushed together during the rotational movement of the switch shaft.

Alternatively, the switch device can also be designed as a switch that can be displaced, for example, in a guide groove. In this embodiment game list of the indicator advantageously arranged on the switch shaft so that it moves with the displacement movement of the switch shaft with this.

Finally, the present invention relates to the use of at least one switch device according to the above-described type for regulating at least one power of a household appliance, in particular for regulating the gas supply of at least one gas burner of a gas range.

Best way to carry out the invention

In order to avoid superfluous repetitions, the following explanations concerning the embodiments, features and advantages of the present invention (unless stated otherwise) refer both to the switch device 100 shown in FIGS FIG. 4 illustrated switching device 100 '.

Im on the basis of FIGS. 1 to 3 1, a switch device 100, namely a rotary switch for regulating a gas range, is shown. The switch device 100 serves to regulate the gas supply to a gas burner of the gas range. For this purpose, a switch shaft 10 rotatable about its longitudinal axis extends from the outer region of the gas range into the interior of the gas range. More specifically, the switch shaft 10 extends through a cooking plate 20 of a cooking point of the gas range.

As in the Figures 2 and 3 shown, a control knob 12 is disposed on the switch shaft 10 for operating the switch shaft 10 on the outside of the gas range.

On the hob plate 20 is a first embodiment of a power range marker 30, which is arranged around the control knob 12 around and marks the size range of adjustable by means of the switch shaft gas supply. The power range marker 30 thus indicates all possible orientations or positions of the switch shaft 10 or all possible power conditions of the gas range, the mark range from the switch position in which the gas supply is interrupted or off, to the switch position in which the gas supply is completely turned on is enough.

In the in the FIGS. 1 to 5 1, 100 'of a switch shaft, the power area marking 30, 30', 30 "is arranged on a translucent surface 20, namely on a translucent hob plate made of glass ceramic or hard glass, such as a ceramic hob, of the gas range , 30 ', 30 "applied to the hob plate 20, for example, printed, or etched or baked in the hob plate 20.

As in particular from FIG. 1 can be seen in the FIGS. 1 to 3 illustrated first embodiment of the power range marker 30, these formed of translucent areas of the hob plate 20, wherein the power area marking 30 surrounding areas not translucent areas the hob plate 20 are. This has the advantage that the power range marker 30 can be illuminated and thus a readability even in unfavorable lighting conditions is possible.

For illuminating the power range marking 30, a lighting device is arranged in the interior of the gas range. This lighting device consists in the FIGS. 1 to 3 illustrated embodiment of six light-emitting diodes 61, 62, 63, 64, 65, 66, which are arranged in such a manner around the switch shaft 10 that they illuminate at any conceivable orientation or position of the switch shaft 10, the entire surface of the power range marker 30.

Above the illumination device 61, 62, 63, 64, 65, 66, a disc-shaped diffuser 70 surrounding the switch shaft 10 is arranged to scatter the light emitted by the illumination device 61, 62, 63, 64, 65, 66.

Between the diffuser 70 and the glass-ceramic surface 20, an indicator 40, namely a blue Plexiglas indicator, attached to the switching shaft 10 of the control knob 12. This indicator 40 rotates with a change in the position or orientation of the switch shaft 10 with the switching shaft 10 about its longitudinal axis. Thus, the indicator 40 is in each case in the beam path of the light emitted by the illumination device 61, 62, 63, 64, 65, 66 to the current position or orientation of the switch shaft 10 associated area 50 of the power range marker 30 light and indicates the set by means of the switch shaft 10 Power state of the gas stove by a blue cooktop display 50.

When in the FIGS. 1 to 3 illustrated embodiment, the indicator 40 is thus a blue plastic strip, which is illuminated from below or from the control knob 12 side facing away and a portion 50 of the power range marker 30, turns blue when it is turned on him.

The power range marker 30 may, as in the FIGS. 1 to 3 illustrated, different power states or switch shaft alignments associated power state symbols 32, 24, 36, 38, approximately depending on the heating power of the gas burner different sized gas flames have. By means of the indicator 40 is, as in the Figures 2 and 3 shown, a continuous indication of the power state of the gas range possible.

Alternatively, the power range marker 30 'may be as shown in FIG FIG. 4 represented, also consist of at least one, for example semicircular, dashed line marking. This power range marking 30 'can be supplemented, for example, by a display 80 which displays the power state numerically, for example by a seven-segment display. Conveniently, the seven-segment display 80 is illuminated by the illumination device 61, 62, 63, 64, 65, 66.

A third embodiment of a power range marker 30 "is shown in FIG FIG. 5 shown. In this embodiment, by means of the switch device 100, 100 'adjustable range of power of the household appliance is marked by at least one threshold arrow. The thickness of the Schwellpfeils at a certain point symbolizes the setting of the switch device 100, 100 'with respect to the minimum 32 or a maximum of 36 adjustable power value.

As in the FIGS. 2 to 4 shown, the control knob 12 can at least partially 14, 16 of the illumination device 61, 62, 63, 64, 65, 66 are illuminated. Advantageously, the indicator 40 is arranged in the beam path of the light emitted by the illumination device 61, 62, 63, 64, 65, 66 to the control knob 12, so that at least one region 14, 16 of the control knob 12 in the same way as the current position or orientation the switch shaft 10 associated region 50 of the power range marker 30 is characterized. In the in the FIGS. 2 to 4 illustrated two embodiments of the switch device 100, 100 ', for example, the scope 14 of the control knob 12 and a Positiönsmarkierung 16 of the control knob 12, more precisely, a visible on the control knob light spot, illuminated with blue light.

The control knob 12 advantageously has in its non-illuminated areas on a color and / or a material or which has a strong contrast to the illuminated areas 14, 16 and thus differs well from these. For example, the non-illuminated area of the control knob 12 may be bright and shiny, such as stainless steel. Alternatively, the non-illuminated area of the control knob 12 may also be dark, about black colored.

The in the FIGS. 1 to 4 The illustrated two embodiments 100, 100 'of a switch device according to the present invention differ from the prior art in that the power state of a gas appliance, namely a gas range, by means of an electrically illuminated switch device 100, 100' is displayed accurately.

The illustrated switch devices 100, 100 'differ from the prior art in that on the switch shaft 10 below the power range marker 30, 30', 30 "a translucent indicator 40 movable with the switch shaft 10 is arranged to determine the exact position or orientation of the switch This power state indication is effected by means of a color shift, namely a blue color, of the light passing through the indicator 40. Advantageously, the area 50 marked by the indicator 40 is illuminated blue, whereas the remaining one is illuminated Power range marker 30, 30 ', 30 "illuminated with colorless light.

Furthermore, the illustrated embodiments 100, 100 'differ from the prior art in that the power area marking 30, 30', 30 "of non-printed, translucent and by the lighting device 61, 62, 63, 64, 65, 66 illuminated areas of around the power range marker 30, 30 ', 30 "around printed cooktop 20, namely a printed cooktop panel made of hard glass or glass ceramic, is formed.

Another distinguishing feature of the prior art is the diffuser 70 disposed between the power area marker 30, 30 ', 30 "and the illumination device 61, 62, 63, 64, 65, 66 which provides uniform illumination of the power area marker 30, 30', 30". allows.

The illumination device shown differs from the prior art in that it has a plurality of light-emitting diodes arranged below the power range marking 30, 30 ', 30 ".

By means of the rotary switches 100, 100 'described above, the power of the gas range can be regulated much more accurately and easily than with conventional rotary switches.
