Definitions

  • the invention relates to a detection and control device for domestic heating apparatus.
  • Home heating appliances especially bathroom heaters, frequently serve as a support for wet towels or towels that may interfere with the operation of the domestic heater.
  • a first object of the invention is to improve the operation of home heating appliances, with a new device for detecting the presence of an object possibly placed on the domestic heater.
  • a second object of the invention is to promote the control of the domestic heating appliance according to the presence or absence of an object to be detected.
  • a third object of the invention is to allow the drying of an object placed on a domestic heater by adjusting the heating power.
  • the subject of the invention is a detection and / or control device for a domestic heating appliance, for the purpose of detecting the presence of an object placed on the appliance, comprising capacitive detectors connected to an electronic management means.
  • the invention also relates to a domestic heating appliance comprising a detection device according to the invention.
  • a domestic heating appliance 1 is for example an appliance used in bathrooms having a glass heating body carrying a surface heating element 2.
  • the terminals 3a, 3b of the surface heating element 2 allow the connection to a power source not shown.
  • the terminals 3a, 3c are also connected by wire connection 4 to an electronic management means.
  • the electronic management means comprises an electronic oscillator making it possible to inject a signal into the surface heating element and to process the response to this signal via a microcontroller, according to a known and commercially available technique.
  • a microcontroller for example, a microcontroller
  • the electronic management means 5 may also comprise a display means 6, for example, with light-emitting diodes or with liquid crystals, intended to display the characteristics of an object possibly placed on the domestic heating appliance 1.
  • the influence of this towel or this cloth overlapping the electrode 2 introduces parallel capacitors in the circuit between the surface heating element 2 and another electrode 3c which may consist for example of the frame of the apparatus 1.
  • the surface heating element 2 then constitutes a surface electrode which is influenced by the presence or absence of an object to be detected.
  • Tests have shown not only that the presence of a cloth or a towel on the heating body can be detected without difficulty, but also that the moisture state of a towel or a cloth can be detected .
  • the electronic management means sends a signal to an unrepresented control means of the domestic heating apparatus for controlling the heating power of the heater. device to the characteristics of the detected object.
  • the heating power is increased as the laundry is not sufficiently dry.
  • the surface heating element 2 may serve as a surface electrode 3a and another comb electrode 3c included in the heating element may constitute the second electrode.
  • This second electrode 3c is insulated with respect to the surface electrode.
  • the invention goes against the prejudices of a person skilled in the art who tries to avoid the influence of moisture on the performance of capacitive sensors.
  • the invention takes advantage of this sensitivity to moisture to quantify the moisture state of the object to be detected, usually a cloth or a wet towel.
  • the fact of using the heating element directly as a surface electrode 2 has the advantage of avoiding any additional electrical insulation, because the heating element integrated in the glass heater is already insulated.
  • the electronic devices manufactured by the American company CYPRESS SEMICONDUCTOR CORPORATION and marketed under the name CAPSENSE can advantageously be used for the implementation of the invention.
  • These electronic devices include digital and analog cells managed by a microcontroller.
  • another domestic heater 10 comprises an outer casing 11 which has on the front face a surface electrode 12 which can be influenced by the presence of an object to be detected.
  • the outer casing 11 also contains another means of domestic heating, for example a sealed or double insulated heating body.
  • the surface electrode 12 has a zone 13 limited in dashed lines that can constitute a display means.
  • the display means 6 or 13 may be replaced by sound or equivalent indicators without departing from the scope of the present invention.
  • a sound indicator can thus be activated to indicate that a towel or a wet cloth must be replaced, or alternatively a towel or dried cloth should be removed from the domestic heater.
