Definitions

  • the present invention relates to a hand-held dryer, in particular a hair dryer, with at least one heating device and a blower and a controller for controlling the heating device and / or the blower, according to the preamble of claim 1.
  • Dryers especially hairdryers
  • a generated by a fan air flow is heated by a heater and directed to an object to be dried, such as hair.
  • a dry power or a temperature of the air flow is usually set by a manual control of a heating power of the heater and / or a blower power of the blower.
  • the disadvantage here however, that the hair to be dried can be damaged, if they experience too high a temperature load.
  • the addition of the dryer by temperature sensors that measure a temperature of the hair can solve this problem only to a limited extent, as too high a temperature on the hair usually means too high a temperature load. Determining the temperature of hair is also difficult and inaccurate.
  • the present invention therefore deals with the problem of providing for a generic dryer an improved or at least alternative embodiment, which is characterized in particular by a simplified and safer handling.
  • the present invention is based on the general idea, in a dryer, in particular a hair dryer, having the features of the preamble of claim 1, at least one motion sensor to be mounted on or in the dryer to measure a movement of the dryer and a heater and / or to control a fan by means of a control as a function of the measured movement.
  • a dryer is understood to be primarily a dryer, it being understood that the statements made are applicable to all hand-held dryers, that is to say, for example, to hot-air blowers.
  • the dryer is usually moved during the drying process, which also moves a generated by the fan airflow.
  • an object to be dried undergoes heat input at different points through a temperature of the air flow.
  • the article locally experiences less heat when the movement of the dryer increases, that is, when the dryer is moved more than at a weaker movement of the dryer or at a standstill of the dryer.
  • the control of the heating power of the heater and the blower power of the fan and thus the dryer power or the air flow temperature depending on the measured movement is therefore a very simple and effective way to change the heat input to the object and adjust, in particular the subject from heat damage and Protect burns.
  • an increase in the air flow temperature is achieved for example by increasing a heating power of the heater and / or by reducing a fan power of the fan.
  • a reduction of the airflow temperature can be achieved, in particular, by reducing the heating power of the heating device and / or by increasing the blower output of the fan.
  • the dryer has a fan, such as a fan, and includes a heater, such as a heating wire, which heats the airflow generated by the fan.
  • the dryer has the above-mentioned control, which allows variation of the heating power of the heater.
  • a motion sensor is now attached to the dryer so that it measures a movement of the dryer, in particular an acceleration.
  • the motion sensor is preferably located in the vicinity of an air outlet of the dryer. It is also conceivable, for example, an optical motion sensor.
  • the motion sensor can be mounted on the dryer but also in the dryer, with internal motion sensors may have a heat protection, which protects them against any harmful heat effects of the dryer.
  • the controller is coupled through a connection to the motion sensor.
  • the controller is connected to the heater and configured to program upon a change in the movement of the dryer the heating power of the heater varies, in particular to change the dryer power or the air flow temperature and thus the heat input to the object. This can be realized, for example, by a variation of an electric current flowing through the heating wire.
  • the controller controls the fan of the dryer in dependence of the movement / acceleration.
  • the blower is for this purpose connected to the controller, wherein the controller varies the blower output of the blower depending on the measured movement of the dryer, in particular to change the dryer performance or the air flow temperature and thus the heat input to the object, for example to keep it equal.
  • Such a change can be achieved in the case of the fan as a fan, by changing a speed of the fan.
  • both the heating device and the blower are controllable depending on the detected movement of the dryer.
  • the controller varies the heating power of the heater and the blower power of the fan depending on the measured movement of the dryer either coupled or individually and depending or independent of each other, in particular to vary the dryer performance and the air flow temperature and thus the heat input to the object.
  • Heater and fan may each be connected to a controller or both may be connected to and controlled by the same controller.
  • a further advantageous embodiment of the dryer additionally has a plurality of motion sensors. These are each mounted individually or together on or in the dryer.
  • the motion sensors have connections to one or more controllers.
  • the individual motion sensors can now be used, in particular by a comparison of the individual detected values of the respective motion sensors, to detect an accurate movement of the dryer.
  • the individual motion sensors are optionally designed to measure different types of movements. For example, motion sensors may be present for movement along the airflow generated by the fan and / or perpendicular to this direction. Also conceivable are motion sensors, the one measure spatial movement.
  • the controller now varies the heating power of the heater and / or the blower power of the fan depending on the measured movement to thereby control the heat input to the object.
  • the heating power of the heater and the blower power of the fan may optionally be controlled depending on a measured motion of a single motion sensor or a combination of motion sensors or all motion sensors.
  • the respective connections between the controller and the heater or the blower and between the controller and the motion sensors are not necessarily made of an electrical conductor. Possible, for example, wireless connections and optical connections. It is further pointed out that in the presence of multiple controls or motion sensors, the controls or motion sensors can each have connections with each other. All connections can also have a return channel, in particular for matching between the individual components.
  • the motion-dependent control can be preferably activated and deactivated, and also dryers are conceivable, which have a combination of manual adjustment of the dryer performance and the motion-dependent control.
  • dryers with a temperature measuring device, which are designed such that they measure the air flow temperature and thus influence the variation of the heating power of the heater and / or blower power of the fan depending on the measured movement.
  • a dryer 1 according to the invention comprises at least one heating device 2, for example a heating wire, and at least one fan 3, here a fan, which are controllable by at least one controller 4, wherein the dryer 1 additionally comprises at least one motion sensor 5 which detects a movement of the Trockners 1 recorded.
  • the designated components of the dryer 1 are housed in the embodiment shown in or on a housing 6.
  • the at least one motion sensor 5 can communicate wirelessly with the controller 4, wherein a wired connection, in particular via a fiber optic cable, is conceivable.
  • the housing 6 comprises an air duct section 7 and a handle 8.
  • the air duct section 7 has openings on two opposite sides which direct an air flow 10 generated by the blower 3 through the air duct section 7.
  • the openings can therefore be divided into an inlet opening 9 'and an outlet opening 9 "with respect to the air flow 10.
  • the fan 3 and the heating device 2 are accommodated on the side of the inlet opening 9' of the air channel section 7, the fan 3 being closer to the inlet opening 9 is placed as the heating device 2.
  • the motion sensor 5 is in the present case outside of the air duct section 7 on the side of the outlet opening 9 "attached.
  • the controller 4 is located in the handle 8 and has no manual adjustment in the present embodiment.
  • the handle 8 also has a connection 11 for power supply.
  • the controller 4 is, as in Fig. 1b shown coupled by connections 12 to the motion sensor 5, the heater 2 and the fan 3.
  • the controller 4 is now programmed or designed such that it has a fan power of the blower 3, in particular a speed of a fan of the blower, and / or a heating power of the heater 2, in particular an electric current flowing through a heating wire, depending on the motion sensor 5 measured movement of the dryer 1 varies, in particular to change a dryer performance of the dryer 1 and a temperature of the air flow 10 and thus a heat input to an object to be dried.

If an increase in the movement is detected, then a path 16 leads to an operation step 17, in that the heat output of the heating device 2 is expediently increased and / or the blower line of the blower 3 is reduced and the drying power or the airflow temperature is changed, in particular to vary a heat input to the object or to keep constant or adapt.
  • These changes can be made in each case depending on or independently of each other or at the same time or with a time delay and thereby be in opposite directions, that is to say an increase in the heating power and a reduction in the fan power and vice versa.
  • the changes can continue to be stepless or in stages. Subsequently, the whole returns via a path 18 to the starting point 13 and the matching starts again from the beginning.
  • the operation step 20 is initiated via a path 19, which now reduces the heating power of the heater 2 and / or increases the fan line of the fan 3 and thus the dryer output or the airflow temperature changes.
  • the changes are made in a similar way to the previous paragraph. Subsequently, the whole returns via a path 21 to the starting point 13 and the matching is repeated.
  • At least one threshold value for a movement change between the last measured movement and the currently measured movement is conceivable, whereby the execution of the operations 17 and 20 takes place only when this threshold value of the movement change is reached or exceeded. This is intended in particular to prevent an excessively frequent variation of the heating power of the heating device 2 and / or the blower output of the blower 3.
  • Fig. 2b shows an alternative or optional procedure.
  • the sequence begins again at the starting point 13 via the path 14 to the comparison section 15.
  • the comparison section 15 the movement of the dryer 1 is compared with the last measured movement. If there is a change in the movement, then a path 13 leads to an operation step 24.
