Definitions

  • the invention relates to a radiant heater for an electric cooking hob, provided with a thermal switch for turning on and off a warning lamp to indicate a state of the hot plate during heating and cooling.
  • Radiant heaters of the above-mentioned type are known, with a built-in thermal switch whose electrical contact is used for switching on a warning lamp indicating that the cooking plate is still "hot” with a hazardous residual temperature, the threshold of which is set at 60-70°C.
  • the thermal switch has to switch the warning contact during the onset of the heating of the cooking plate as well as during cooling to warn of a residual temperature higher than the aforesaid threshold value.
  • the bimetallic sensor does not make direct contact with the hot plate, but the switch response time should be correlated to the actual temperature of the heated plate zone.
  • the thermal switch is situated on an peripheral insulating zone of the heater receiving proportionally the heat transmitted to the plate, so that the temperature value reached in the sensing element, always higher than on the plate, closely follows the changes in said real value in the plate.
  • the switch actuating point is set at a suitable temperature point for switching in both plate heating and cooling process or directions, taking into account also the thermal hysteresis of the switch, which leads to a lower switching point during cooling.
  • the problem of the temperature in the outer wall of the heater becomes critical when the ceramic body of the bimetallic sensor is submitted directly to heating from the adjoining heaters, so that the sensitive disc of the bimetallic switch may reach a temperature of around 100°C, and it loses correlation with the actual temperature of the plate area it has to detect.
  • the outer heating of the built-in bimetallic switch may come from heat sources below the heater.
  • the thermal switch for turning on the warning lamp is fixed at the peripheral edge of the heater and for its operation it has an expanding rod coupled to the heating resistors from which it receives heat.
  • Publication US-6,756,569-B2 describes a radiant heater or "warmer” only for warming, which uses a bimetallic switch for turning on a "hot” plate warning lamp.
  • the sensor is built into the heater secured between the peripheral insulating ring and the horizontal base of the heater, in a hole space shaped to the outline of the body of the sensor. Owing to the fact that the ceramic body has no heat insulation against the transmission of external heat, the bimetallic disc may reach a temperature of more than 100°C, even when the heater if off.
  • the temperature detected at the bimetallic sensor follows an almost asymptotic slope above 100°C (represented by the dotted line in figure 4 ) and the response time of the sensor in opening the electrical contact is very long and out of touch.
  • the sensor bimetallic disc reaches a temperature 40°C lower than in the other case. It is thus hard to find a setting point for the switching of the electrical contact in both directions.
  • one certain point of actuation of the sensor being set after adding the differential interval due to the actual switching hysteresis of the switch, the temperature difference in the plate area, the difference between the moment of closure and the moment of opening, may reach as much as 70°C, even larger than an acceptable signalling interval of 50 - 80°C.
  • thermal switch or bimetallic sensor used in the heaters in the prior art are of the type described in US-A-4059817 , provided with a cylindrical sensor body and a heat receiving metallic base in direct contact with the internal bimetallic temperature-sensitive disc.
  • Another type of known bimetallic thermal switch incorporated in a radiant heater is described in publication DE-1123059-A , and it is also compact with a ceramic body whose heat-receiving side presents a recess through which a bimetallic plate is deformed, while the terminals are situated on the opposite side of the body, facing longitudinally.
  • GB-A-2 316 283 discloses an electric heater with a cooking plate, a heating resistor and a thermal sensor comprising bimetallic sensors.
  • the heating resistor is provided in an electrically insulating layer, said insulating layer being fixed to the cooking plate.
  • EP-A1-0 249 721 describes an electric hotplate comprising a cooking plate, heating resistors and a thermal sensor comprising a rod-like, linear temperature sensor.
  • US-A-2005/0274710 discloses a radiant heater according to the preamble of claim 1.
  • the object of the present invention is an electric radiant heater as defined by the combination of features enumerated in claim 1.
  • the thermal sensing switch is fixed inside the heater separate from the cooking plate, isolated there from the influence of the adjacent heaters of the cooking hob.
  • the temperature value detected is faithfully correlated to the true value in the heated plate area, both during heating and during cooling. Thereof the actuation of the switch is thereby achieved in both directions within an acceptable residual temperature range in the plate area of 65° ⁇ 15.
  • the preferably bimetal type thermal switch is disposed in an air cavity within the heater under the cooking plate, wherein the heating resistors are mounted.
  • the thermal switch used as a bimetal sensor has a compact body whose heat receiving side for the sensing element is directly facing the radiation of the heating resistor, said receiving side resting according two embodiments closed to a portion of the heating resistor or otherwise over a resistor segment engaging therewith, depending on how is conformed the insulating surface for the heating resistor portion support and guide. Positioned in this way, the bimetal sensor is isolated from the influence of the external heating produced by the adjacent cooking heaters switched on at the same time. A quick sensor response to plate heating is also achieved as well as precise temperature detection during cooling, closely correlated to the real value in the heated plate area.
  • the response time to cooling is not delayed unnecessarily, due to the fact that the bimetallic sensor is isolated from the metal cover of the warmer heater, through the interposition between them of the peripheral isolating wall thereof, and its air cavity in which the sensor is enclosed inside the heater.
  • the radiant heater according to the invention does not use additional fixing means either for the bimetallic sensor, since it is situated up against a central surface of the heating resistor insulating carrier or base.
  • the sensor is secured and pressed here by the elastic force of rigid electrical connection cables. In this way, its position relative to the heating resistors is fixed and does not vary either moved by the thermal constraints in the sensor body.
  • a preferred embodiment of radiant heater 101 is attached to cooking plate 2 of a cooker hob with various radiant heaters (not represented in the drawings), which are arranged below the cooking plate and close to one another, and the radiant heater 101 is formed of a cover or metal tray 3, an insulating base 4 holding a least one heating resistor, a peripheral insulating ring 6 in contact with the cooking plate, a compact thermal switch or bimetallic sensor 107, disposed in an air cavity 13 formed below the heated plate area 2a, between the insulating base 104 and the insulating ring 6, and an electrical connector 8, which transmits the power directly to the resistors.
  • the bimetallic sensor 107 has a compact, electrically insulating body 107a made of ceramic material resistant to the high temperature that is transmitted from the heating resistor 105. It is constructed with an external metal base 107b, 107d receiving heat on one side of the compact body 107a, and a bimetal disc 107c sensitive to the temperature connected thermally to said metal base 107b, 107d.
  • a normally-open electrical contact 109 of the sensor is actuated at the regulated switching point SWC' ( FIG. 4 ), which, upon closing, provokes the ignition of a signalling lamp or other "plate hot" warning device (not represented in the drawings) advising of the residual temperature of the heated plate area 2a.
  • the power of the heater described here as a specimen embodiment is 250 W, normally lower than the power of the adjacent 750-1250-watt hotplates.
  • the heating resistor 5 may be made in planar or wire coil form and it is installed on a central surface area 104a of the insulating base guided in a groove 110.
  • a commercial bimetal sensor 107 is chosen on grounds of economic cost and its compact body 7a is preferably square section and low height so as not to interfere in the installation of the glass ceramic plate on the radiant hotplate.
  • the height "H” of the air cavity 13 is 20-25 mm, similar to that of other heaters.
  • a separating space "B" for instance of 3 mm or less, i.e. a fitting clearance "B” the same as that of other cooking hotplates in order to use the same insulating ring 6 and metal tray 3 pieces.
  • a minimal separating space "B” from the plate area 2a is preferable in order to improve the correlation between the "ZT" temperatures in the area of plate 2 and the "ST" in the bimetal sensor 107.
  • the compact body of the sensor 107a is insulated from the external thermal influence of the adjacent heaters, separated from the insulating ring 6 by an intervening space "S", the size of which depends on the distribution of the segments of heating resistor 105 and its coil-like configuration.
  • the bimetal sensor 107 is disposed in the air cavity 13 of the radiant heater 101, resting on the central surface area 104a of the insulating base above a segment of resistor 105a in order to improve heat transmission form the heating resistor 105 to the bimetal sensor 107.
  • Said heating resistor segment 105a is guided in a segment of insulating guiding groove 120, 120'.
  • the heat-receiving metal base 107b, 107d is supported on the segment of guiding groove 120, substantially in contact with the resistor segment 105a, or separated from the latter by a very small accidental space, depending on the dimensional deviations of the insulating base 104a and the compact body of the sensor 107a.
  • the metal base 107b, 107d is insulated electrically from the resistor segment 105a.
  • an embodiment of heater 101 is shown in which said resistor segment 105a is housed in an insulating groove 120, of a width "W” and a depth "P".
  • the metal base 107b of the bimetal sensor is completely flat and straight and the resistor segment 105a is fully sunken in the housing groove 120.
  • the depth "P” and the width "W” of the groove are greater than the diameter " ⁇ " of the resistor 105a.
  • an air channel 121 is formed which constitutes a source of heat for the bimetal disc 107c.
  • a version of radiant heater 101 is shown in which said resistor segment 105a is fixed in a surface guiding groove 120' the same as the heating resistor 105 guiding groove 120'.
  • the resistor segment 105a stands proud here of the insulating support surface area 104a, and the sensor metal base 107d lies above the guiding groove 120' in contact with the resistor segment 105a, forming an air channel 122 that transmits heat to the metal base 107d.
  • the metal base 107d is substantially straight but with two projections squared on the side edges, between which the resistor segment 105a passes, standing proud of the insulating base 104a.
  • the metal base 107d may also be formed according to other versions, for example by means of two inclined walls 114 forming a triangular cavity for the resistor segment 105a on the insulating support surface area 104a, or else with a single lateral projection 114 forming an angle with the straight metal base 107d, thus positioned with an inclination on the insulating support surface area 104a.
  • a cavity is formed on the insulating surface area 104a, by way of which the resistor segment 105a passes, making substantially a thermal contact with it.
  • the sensor electrical contact 109 is connected by two rigid cables 111 to the peripheral electrical connector 8, from which the signalling lamp is illuminated via a line 12.
  • the elasticity of the metal cables 111 extended with a small angle of inclination produces a force "E" applied to the body of the sensor 107a against the insulating support surface 104a. The position of the sensor 107 is thus held fixed against the movements produced by the thermal stresses.
  • the temperature curve "ZT" has been measured in the heated plate area 2a, with a food container on top, and has reached around 150°C.
  • Characteristic of a commercial type thermal switch or bimetal sensor 107 it is an intermediate setting of the switching point SWC', SWO' of the electrical contact between the two rising and falling values, respectively, which has been found as appropriate 100°C.
  • a differential hysteresis value "AThy" between SWC' and SWO' is represented.
