Definitions

the invention relates to an air circulation heating apparatus comprising a housing with an air inlet and an air outlet between which are placed means for supplying a flow of hot air which comprises means for circulating air. air and air heating means, detection means for measuring radiation emitted by a body subjected to the flow of hot air and means for controlling the heating means according to the measurements of emitted radiation.
It may for example be a hair dryer, an electric circulating radiator or the like.
Hair drying consists in evaporating the water retained by the hair using a flow of hot air. This is obtained using a fan which delivers the air flow, which is itself heated by coming into contact with heating means. At the beginning of the evaporation process, the water retained by the hair forms a heat shield which avoids burning the scalp. As the water evaporates, it becomes less and less screen and the flow of hot air can create a burning sensation and even cause a burning of the scalp as well as drying and hair deterioration.
This method consists in remotely measuring the temperature of the hair using an infrared sensor placed at the outside of the hair dryer body.
An optical allows to target the place of the hair subjected to drying.
the infrared detector acts on the heating means when a predetermined temperature is reached.
a hair dryer of this type has drawbacks.
the aiming point of the infrared sensor must coincide with the heated zone. We must therefore maintain the hair dryer at a fixed distance for correct operation. With too short or too long distances, 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 damaging 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 on the user too precise handling of the hair dryer.
This object is achieved with a heating device for which the detection means are arranged in the path of the hot air flow in direct line between the body and the air circulation means.
the detection means are placed on or very close to the axis of propagation of the flow of hot air.
the detection means may be desirable to provide means for reducing the disturbing temperature rises of the detection means from the heating means. It may be a screen preventing direct arrival of the flow of hot air on the detection means.
FIG. 1 represents a hair dryer 5 comprising a housing 10 and, between an air inlet 11 and an air outlet 12, means 13 for air circulation followed by means 14 for heating the air in circulation.
the air circulation means 13 are formed for example of a fan.
the air circulation means 13 and the means 14 are connected to an electrical energy supply 16 and for heating the air can be operated using a switch 15.
the user directs the flow of hot air 17 which leaves the air outlet 12 towards the hair 8.
means 20 for measuring the radiation of heat emitted are placed on the path of the hot air flow 17 through the hair, for example an infrared sensor.
the sensor 20 is combined with means 18 for controlling the heating means 14 according to the temperature measured on the hair. For this, a fixed temperature is fixed and when this is reached, the control means 18 reduce or stop the heating and / or ventilation means 14.
the arrangement of the sensor allows it to detect temperature variations in the area of hair that receives the flow of hot air. There is no longer a parallax effect and therefore a distance to be observed for the operation to take place properly.
the senor is placed on the axis XX of symmetry of the hot air flow. It can nevertheless be offset.
thermocouple sensor any sensor capable of measuring infrared radiation emitted by the hair and capable of being housed in the path of the hot air flow while only slightly disturbing it.
temperature-dependent resistive sensor pyroelectric sensor, thermocouple sensor or others.
a sensor is used formed of a plurality of elementary cells developing a thermoelectric power.
a cell is formed by a stack of conductive and / or semiconductor layers such that the cell develops a difference in electric potential induced in response to a flow of heat.
Such a sensor is, for example, described in the documents FR 2,471,055 and FR 2,598,803.
protection 22 which prevent the hot air from directly striking the rear of the sensor.
It can be a protective sleeve which deflects the flow of hot air away from the sensor.
the sleeve can be reduced to a screen 23 ( Figure 3).
the limitation of the opening of the thermal beam can be obtained by putting a part 25 projecting from the sensor 20 (FIG. 5).
