Definitions

  • the invention relates to a heater with air circulation, for example DE-A-4208680, comprising a box with an air inlet and an air outlet between which are placed means for deliver a flow of hot air which include means of air circulation and air heating means, detection to measure radiation emitted by a body subjected to hot air flow and means for controlling the means of heating according to the radiation measurements emitted.
  • a heater with air circulation for example DE-A-4208680
  • It can be for example a hair dryer, a electric air circulation heater or others.
  • Hair drying involves evaporating the water retained by the hair using a flow of hot air. It is obtained by means of a fan which delivers the air flow, itself heated by coming into contact with heating means. At beginning of the evaporation process, the water retained by the hair forms a heat shield which avoids burning the scalp. As and as the water evaporates, it becomes less and less screen and the flow of hot air can create a burning sensation and even cause burning of the scalp and dryness and deterioration of the hair.
  • a hair dryer of this type has disadvantages.
  • the aiming point of the infrared sensor must coincide with the heated area. We must therefore maintain the hair dryer at a fixed distance for operation to be correct. With distances that are too short or too long, the measurement is then erroneous due to the parallax and the intervention of the detector on the heating means is not carried out correctly which causes the burns described above. this is particularly harmful when a third person handles the hair dryer: hairdresser for a client, drying a child or when a person dries long hair where there is then no sensory alarm.
  • the object of the invention is to avoid any risk of burns when using such a heater.
  • the object of the invention is to avoid any risk of burns by not imposing user too precise handling of the hair dryer.
  • the detection means are placed on or near the axis of propagation of the hot air flow.
  • detection means may be desirable to provide means to reduce disruptive temperature rises in detection means from the heating means. he can be a screen preventing direct arrival of the hot air flow on the detection means.
  • FIG. 1 represents a hair dryer 5 comprising a box 10 and, between an air inlet 11 and an air outlet 12, air circulation means 13 followed by means 14 for heating circulating air.
  • the air circulation means 13 are formed for example a fan.
  • the means 13 for air circulation and the means 14 are connected to a power supply electric 16 and to heat the air can be turned on operation using a switch 15.
  • the user directs the hot air flow 17 which leaves from the air outlet 12 to the hair 8.
  • the air flow path is placed hot 17 means 20 for measuring the heat radiation emitted through the hair, for example an infrared sensor.
  • the sensor 20 is combined with means 18 for controlling the heating means 14 from the temperature measured on the hair. For that, we fix a certain temperature and when this is reached, the control means 18 reduce or stop the means 14 for heating and / or ventilation.
  • the arrangement of the sensor allows this to detect temperature variations in the area of hair that receives the warm air flow well. There is no more effect parallax and therefore distance to respect for the operation is done properly.
  • the sensor is placed on or near the XX axis of symmetry of the hot air flow. It can nevertheless be offset.
  • any sensor capable of measuring infrared radiation emitted by the hair and able to be accommodated on the path of the hot air flow by only disturbing it weakly For example: resistive sensor depending on the temperature, pyroelectric sensor, thermocouple sensor or other.
  • thermoelectric power preferably uses a sensor formed by a plurality of elementary cells developing thermoelectric power.
  • a cell is formed by a stack of conductive and / or semiconductor layers such that the cell develops a difference in electrical potential induced in response to heat flow.
  • Such a sensor is, for example, described in documents FR 2,471,055 and FR 2,598,803.
  • Limiting the opening of the thermal beam can be obtained by putting a part 25 projecting from the sensor 20 (figure 5). We can also obtain the limitation of the opening by placing a lens 26 (figure 6) which focuses the radiation thermal on sensor 20.
