Definitions
- the invention relates to a heating device according to the preamble of claim 1.
- a heating device is in particular for a cooking area with a glass ceramic hob suitable
- the heating time or warm-up time for radiant heaters as heating devices on the one hand depends on a adjusted glass-ceramic surface temperature and the quality of the cookware used and on the other hand, from the rated power of the radiant heater and thus its power density. In many cases, it is desirable to shorten this cooking time to a comfortable operation and to achieve fast cooking.
- the power density of a radiant heater However, it can not be increased to infinity. at Radiant heaters with BandMapleitern can from a certain power density the heating conductor temperature is no longer in the specified Upper limits are kept.
- Values for power densities in such radiant heaters are called, which represent a good compromise between the cooking time, quality of the cookware used and the heating conductor temperature.
- An advantageous power density can be close to 8 watts / cm 2 .
- radiant heaters with a nominal diameter of 140mm and 180mm such a power density is used successfully.
- the invention is based on the object, an aforementioned heating device to deal with the problems of the state of the Technique can be avoided and especially the size of a Radiant heater regardless of the power density or a Switching capacity of protection temperature limiters made more variable can be.
- a heating device is in at least a first and split a second area.
- a first area can be from monitored for a first over-temperature fuse. This can for example, be a rod regulator or a protection temperature limiter, the at least partially overlaps this first area or above runs.
- the first area has a maximum first power. This is matched to the above values.
- a second area of the heater is operated without monitoring by the first overtemperature fuse.
- the second area is operated at all without over-temperature protection. This is achieved by the maximum area coverage of the second area being approximately 2.5 watts / cm 2 .
- the heating device divided into two parts, so to speak.
- a first area is operated with a critical power density and must therefore have a protective temperature limiter.
- This first area can be chosen so large that the protective temperature limiter the resulting power just manage or switch.
- the area of the To increase radiant heaters a second area is added. This second area will in any case be without supervision operated by the over-temperature fuse of the first area, preferably without any monitoring by an overtemperature fuse.
- a value is chosen as the power density, which for a glass ceramic is technically possible and permissible.
- a separate over-temperature fuse could be used for the second Be provided area. This would increase the effort, but also improve safety.
- the second region can rest against the first region, advantageously at least along the half outer border. This gives you an approximate elongated heating device.
- the second area surrounds the first area, where they can be arranged concentrically. While the lateral connection of a second area to a first area in about a known elongated roasting heater corresponds, is a concentric arrangement for use either smaller or large round cookware advantageous.
- the performance for the first range more than that for a radiant heater of this size usual basic service amount.
- the performance the maximum value of the overtemperature fuse for example one Stabreglers, approach.
- one performance for the first Range of a maximum of 2500 or 2700 watts be provided at one round area with a diameter of 230mm.
- the first area a switchable power have, which can be switched to the basic power. It is provided that the maximum first power is then present if the switchable power is also applied.
- a switchable Power can be, for example, a boil or the like his.
- the performance for the second area may, in particular due to the lower power density, much lower. For example 600 watts can be provided here. Because this performance is beneficial in the outer or edge region is present as a second area, in which also Cooking pots with not very even floor get up, this is Performance in any case decreased. Thus, too much warming a glass ceramic hob avoided here. Furthermore has in heating mode without pot, so if no heat output removed is, the glass ceramic in the edge area due to the larger area the biggest heat loss. Even so, she is overheating protected.
- the heating device have a controller or be connected to it.
- This controller can be an additional contact to the circuit of a basic service of Heating device or a switchable power for the first Range to the total combined maximum first power.
- the additional power can be defined, for example, as a boost and be used.
- the heating device can have an electronic control, for example, with a touch switch arrangement for input.
- Another relay can be provided to the switchable Power in addition to the base load to the total maximum first To switch power.
- a radiant heater is used as the heating device, which have a heating conductor made of resistance material can.
- the heating conductor is preferably in a so-called flat band shape, where he is standing upright on an insulating pad and partially embedded in it.
- a radiant heater 11 is shown in plan view, as he known per se. Its heated area is controlled by a rod regulator 13 overlapped.
- the temperature limiter or rod controller 13 is with his Housing 14 attached to the side of the radiant heater 11.
- Of the Sensor rod 15 protrudes in the radial direction over the center of the radiant heater 11 a bit out.
- the heating area of the radiant heater 11 is subdivided into a first one innermost region 17.
- the first region 17 is of an annular surrounded in the middle second area 19. This in turn is from Surrounding a relatively narrow circumferential third region 21, which forms the outermost heating area.
- the first region 17 is formed by first heating coils 18, the are laid meandering.
- This basic structure of a radiant heater For example, from EP 590 315, incorporated herein by reference expressly referred to.
- the second heating area 19 is formed by second heating coils 20.
- the third region 21 is again formed by third heating convolutions 22, which, as can be seen from Fig. 1, from a single loop consist.
- the Schuwindened 18, 20 and 22 are for example advantageous a heating tape formed in upright ribbon shape. You can be specially selected with regard to their characteristics certain power distribution or area performance achieved during operation or to achieve overall performance. It can also be seen that the Heating coils 18 of the first region 17 with a smaller distance from each other run as the second heating coils 20 of the second area 19th
- a connection of the heating coils to a power supply such as power electronics or a so-called clocking energy regulator.
- the heating coils 18 and 20 of the first and second areas are respectively over the top terminal lug 24a contacted, as can be seen.
- This connection banner 24a is connected to the housing 14 of the rod controller 13. Your electrical connection is thus monitored by the rod controller 13 and interrupted in case of overheating to the switch off the first heating area 17 and the second heating area 19.
- the rod controller 13 in this way and a distinction between the first area 17 and the second region 19 in overtemperature case not possible. It would be insofar as possible in a further embodiment of the embodiment, Such a distinction is possible by means of a further bar controller do. However, this plays for the invention in the frame discussed here not matter.
- the third heating coil 22 of the outer third region 21 is over the Connection lugs 24c and 24d connected. These are without that Interposing the rod controller 13 connected to a power supply. They are therefore not monitored by the rod controller 13 concerning overtemperature.
- FIG. 2 is a schematic thermal image of the radiant heater.
- FIG 11 of FIG. 1 in operation. Due to the different surface markings the temperature that prevails is displayed. ever brighter, the higher the temperature. The gradation is per brightness level 10 ° C.
- the first area 17 is predominantly the brightest, with the temperature here is between 545 ° C and 564 ° C respectively at about 555 ° C.
- the second region 19 has temperatures in the range of 524 ° C to 544 ° C.
- the third region 21 has predominantly temperatures in the Range between 494 ° C and 514 ° C or about 500 ° C.
- the radiant heater 11 is a two-circuit radiant heater. It has a diameter of 230 mm and a total nominal power of 2800 W. It accounts for the first area 17 1100 W, the second area 19 also 1100 W and the third area 21 600 W. This 600 W are the so-called unprotected or unregulated power. From Fig. 2 it can be seen that here the temperature in about 50 ° to 60 ° lower than in the first or second region, which are centrally in the radiant heater 11. Further, the area power of the third region 21 is less than 2.5 W / cm 2 , while the power density in the first and second regions is 7.8 W / cm 2 .
- Fig. 2 is thus proven that with heating areas with the previously described properties, ie in particular the outermost Heating area with low area performance, a radiant heater with additional power can be provided, which does not have a Rod controller or not regulated by a single common rod controller must become.
- the radiant heater In the operation of the radiant heater, it is such that in single-circuit operation only the first area 17 is active. In the two-circuit operation of the second area 19 and the third area 21, although electrically separate, but timed together.
- the third heating area 21 could be the same be switched off, but not directly by the rod controller 13, but by its property as a signal generator indirectly. This Although not always because of the thermal load on the surface of the third area 21 is necessary. This would be a uniform Operation of all heating areas possible, so not from the glow pattern of the radiant heater, the outermost area continues to glow brightly, while the central area is dark.
