Definitions

  • the invention relates to a temperature sensor for a radiant heater, which temperature sensor has a first expansion element formed as a tube with a housing of a switch, which is firmly connected to a further expansion element formed as a rod in the region of its free end, wherein the two expansion elements have different thermal expansion coefficients, and the switch has at least one biased against a position and a contact bearing contact spring and one of the expansion elements is acted upon by a spring acting in the axial direction, wherein on one side of the contact spring of the rod and on the other side, the spring in the axial direction of the rod acts, wherein the spring acts against the rod via a support.
  • Such temperature sensors are widely used where e.g. electrically or gas heated devices such as hotplates, radiant heaters of glass ceramic cooking units, oven muffles or the like are to be protected from overheating.
  • US 3 004 123 A shows a comparable temperature sensor for a radiant heater, which temperature sensor comprises a tube connected to a housing of a switch, which is firmly connected to a rod in the region of its fixed end, wherein the tube and rod have different coefficients of thermal expansion, and the switch a biased against a position and a contact-bearing contact arm and one of the expansion elements is acted upon by a spring acting in its axial direction, wherein on one side of the contact arm of the rod acts via a transmission member and wherein the spring acts against the rod via a support.
  • EP 279 368 describes a prior art temperature sensor system.
  • the active portion of the temperature sensor corresponds to the length over which the tube and the inner rod are arranged inside each other.
  • the different thermal expansions of these two parts lead to a differential length when the temperature sensor is heated, which is used to switch the contact system.
  • the position of the axially movable inner rod to Switching system or the contact spring determines and thus given the switching temperature of the contact spring.
  • the contact spring is indirectly controlled with a plunger from the rod at a temperature of the sensor probe system in a radiant heater.
  • the contact spring is fixedly connected in the prior art with the spring bearing, e.g. with the help of welding or riveting.
  • the contact spring is designed as a snap spring.
  • the main thermal contact springs are self-closing, i. the contact system is closed when the indirectly acting plunger does not touch the contact spring.
  • the bias in the contact spring is a minimum.
  • With increasing temperature of the plunger acts with a certain operating force on the contact spring, which is preferably wave-shaped in the transmission area.
  • DE 24 22 625 describes a temperature limiter for electric hotplates, the rod without translation acts directly on the snap element of the snap-action switch.
  • This snap-action switch is limited to temperature ranges of 400 ° C and also has a snap hysteresis path of less than 2/100 mm.
  • an adjusting screw is screwed into the outer tube at its free end, on which the transmission rod is supported.
  • the thread quality of the provided on the outer tube internal thread is set only within large tolerances because of the difficult to deform tube material, which has the effect that the wear of the threading tool is very high and fast.
  • the poor thread quality mainly affects the thread flanks and the tolerance deviations of the thread throat diameter.
  • AT 386 673 discloses a temperature limiter disposed between a gas burner body and a glass ceramic cooking surface heated therefrom, the tube of the Temperature sensor is enclosed by a surrounding surrounding cladding tube.
  • a snap spring is mounted with an additional movable spring arm which carries at its end a contact piece, which ensures the mechanical contact between the ceramic rod and the actuation point of the snap spring.
  • the system is limited to a single-loop controller.
  • the conventional temperature control systems are designed for heaters with 1200 W to 2300 W peak power.
  • the contact spring is claimed up to the load limit and beyond, often repeated, or cyclic stresses lead to irreversible material changes even if the mechanical stresses in the contact spring are below the yield point. These phenomena are called fatigue designated. The signs of fatigue are largely dependent on the state of stress of the material and on the thermal load.
  • the aim of the invention is to avoid these disadvantages and problems mentioned above and to propose a temperature sensor, in which a rapid fatigue of the contact spring and an additional, the axial movement of the inner rod in the sensor tube enabling, spring element is avoided.
  • the mechanical and / or thermal transfer in the region of the contact spring should be optimized for the switching point accuracy of one or more contact systems.
  • the proposed measures ensures that the contact spring between the rod and the acted upon by the spring bearing is clamped.
  • the contact spring is brought at a corresponding increase in the temperature by the spring acting on the support in its open position. It is therefore possible to elastically bias the contact spring in the cold state of the temperature sensor, wherein the mechanical stress in the contact spring decreases with increasing temperature. It result at the same temperature or current load, compared with the known solution of the indirect snap mechanism, a significantly lower voltage load on the contact spring, just as the support on the support spring takes over tasks that must take over the contact spring itself in the known solution. This has a positive effect on material fatigue.
  • Another advantage of the support is a cooling effect away from the contact spring by heat conduction processes. Due to the position of the supporting compression spring on the heat input of the sensor tube and inner rod side facing away from the contact spring, the heat dissipation of the introduced into the compression spring heat in the direction of controller housing and consequently regulator environment, the temperature load of the spring material so far reduced that the fatigue of the material of this additional spring element can be avoided and the stability of the switching point position of the contact spring is ensured by the constant supportive effect of the compression spring. Thereby, the contact spring also higher, in terms of temperature and electrical stress, are claimed.
  • the support also allows easy production of two- or Mehrarrathermostaten, such as for a hot display, including a plunger as a transfer member, which is arranged as an extension of the rod coaxial therewith. With such a trained additional transfer member exactly every small axial extent is transmitted directly to a second contact system.
  • the spring acting against the rod is supported on a housing-fixed abutment and acts via a spring plate on the support.
  • the spring force can be defined very well.
  • the spring acting against the rod is supported on a spring plate variant detachably fastened to the housing and acts on the support via the spring plate.
  • This preferably made of a metallic material Federtellertine has significant mounting technology and processing advantages and increases by direct heat conduction from the spring into the spring plate, the heat dissipation serving metallic surface, whereby the temperature loads on the contact spring and the spring are further reduced.
  • the second contact spring has a bearing on the support and the rod guided in the pipe towandten side adjacent plunger is controlled, which passes through this and is connected to a cooperating with the second contact spring sleeve.
  • the second contact spring is controlled by a on the support and its side facing away from the rod guided rod in the side ram, which interspersed with this and with a the second contact spring cooperating sleeve is connected. This ensures minimal fatigue and optimal transmission for both contact systems.
  • an adjustment spring is supported on a collar of the sleeve, which is further supported on the plunger. Such adjusting spring facilitates a precise adjustment of the temperature sensor to predetermined temperatures.
