Definitions

  • This invention relates to a hair treatment device and a corresponding method for hair treatment.
  • Hair treatment devices in particular include hair dryers, curling irons and straighteners.
  • the invention can be used both in the private sector and by hairdressers.
  • the invention relates to a temperature control for hair treatment devices and an associated method.
  • the registration GB 2 147 204 A (registered by: JH Downey ) discloses a hair comb that has a moisture sensor. This comb should be able to visually indicate the drying status of the hair. It can therefore be used with a hair dryer, for example. A user could then, for example, hold the comb in one hand and the hair dryer in the other hand and, depending on the display of the comb, direct the hot air stream from the hair dryer to areas of the hair that are still moist.
  • the patent application GB 2 432 310 A1 discloses a flat iron with a temperature measuring unit and a circuit. These should ensure that the straightener can only be switched on at a certain minimum temperature. Suitable minimum temperatures can be between 0 ° C and 10 ° C according to this disclosure. As described in the application, switching on at temperatures below such a threshold value could be harmful, especially since the straightening iron can then be damaged by condensation formed.
  • the European patent specification EP 0 176 003 B1 (Wella AG) discloses a method for measuring and regulating the moisture content of the hair, which can be used with hair drying hoods.
  • Such hair dryer hoods as they are typically used in hairdressing salons, should be equipped with a return air duct.
  • An air humidity sensor can then be installed in this return air duct. This sensor in turn is to generate a signal to switch off the drying program.
  • a hair dryer with an infrared radiation source and infrared radiation sensors is known, in which the ratio is used for two measured infrared absorption bands as an indicator of the hair moisture in order to regulate the temperature of the hair dryer.
  • the European patent application EP 1 400 187 A1 discloses a circuit with which the temperature of a flat iron can be kept constant. Like many other circuits, this exemplary circuit is designed to record measurement data from a temperature sensor and to keep the straightening iron as constant as possible at a preset temperature. The temperature sensor is therefore not used to vary the temperature, but on the contrary, to keep the temperature set once constant.
  • the object of the present invention is to offer a hair treatment device and a corresponding method with which hair properties are measured and temperature control in the hair treatment device is used.
  • the invention relates to a hair treatment device and a corresponding method for hair treatment.
  • Hair treatment device which is suitable for heating hair and which also has a heating part which is heated to an initial temperature and the temperature of which is regulated via a temperature control, the hair treatment device being assigned a first and a second sensor which measure data, the sensors Read out temperature data from which a characteristic value can be generated depending on the condition of the hair, the characteristic value influencing the temperature control, the first sensor and the second sensor being provided opposite one another, and a temperature difference being measurable between the first and the second sensor, and wherein the characteristic value is the temperature difference depending on the condition of the hair.
  • the present invention thus generally relates to a hair treatment device.
  • This can be a hair treatment device for professional use, i.e. one that is usually used in a hairdressing salon.
  • the hair treatment device can also be one of the usual devices for use in the private sector. These include, in particular, hair dryers, hot air brushes, curling irons and flat irons. These devices each have at least one heating part, which is designed in different forms depending on the device.
  • air dryers there is usually an air heater, which typically consists of an arrangement of heated wires.
  • Other devices usually also use resistance heaters, for example in the form of heating plates in the case of a flat iron.
  • non-electric heating is also provided, e.g. for gas-powered devices.
  • this heating element When the device is switched on, this heating element is heated to an initial temperature. In individual cases, the device is used before this temperature is reached. However, the initial temperature is specified when the device is switched on. For example, a simple switch-on button can be considered, in which further temperature selection is not possible. In addition to the switch-on button, a controller can also be provided with which an initial temperature can be selected.
  • the temperature of the heating part of the hair treatment device is now regulated via a temperature control.
  • This temperature control can already regulate the initial temperature or it becomes active as soon as the initial temperature is reached and serves to regulate the further temperature curve. Switching off the device is not the task of temperature control. However, as an alternative or in addition, in particular with straightening irons and curling irons, it can also be considered that the temperature control can also switch off the device. The temporary and permanent shutdown of the heating part can be considered.
  • a sensor is assigned to the hair treatment device. This measures data from which a characteristic value can be generated depending on the condition of the hair.
  • the sensor can be installed in the hair treatment device, for example.
  • the sensor is placed in an attachment part to the hair treatment device. Such an attachment would be, for example, a push-on nozzle for a hair dryer.
  • the sensor is provided in a separate component, which essentially only takes on measuring tasks.
  • This sensor can measure various suitable data from which a characteristic value can be generated depending on the condition of the hair.
  • data is hair temperature.
  • data are the hair firmness or the hair moisture.
  • This data can be measured directly on the hair, but it can also be measured indirectly.
  • the hair temperature has an influence on the temperature of a component lying against the hair, such as a heating part for contact with the hair.
  • further useful data can be can also be generated by measuring the pulling force with which hair is pulled over at least one surface. The measurement can be carried out with a single surface or with several, in particular two, surfaces. The two surfaces can be pressed against each other.
  • the two heating surfaces of a hair straightener or the heating and clamping surfaces of a curling iron can be considered.
  • a characteristic value is to be generated from this data depending on the condition of the hair.
  • This can be a characteristic value selected from only two values or a characteristic value selected from a predetermined number of values or also a characteristic value selected from a continuum of numerical values.
  • this characteristic should now influence the temperature control.
  • a simple way of influencing is to raise or lower the temperature. It would also be possible for the characteristic value to vary the temperature along a specific temperature curve.
  • the sensor reads out temperature data in the hair treatment device.
  • the hair treatment device has two sensors.
  • a characteristic value is generated which is a temperature difference which depends on the condition of the hair. For example, the treatment temperature can be increased if the temperature difference is large, or decreased if it is small.
  • Such devices typically have two arms which can be opened and closed and between which the hair is passed. At least one arm usually has a heating surface, often both arms each have a heating surface. The opposite arm can have a contact surface with which the hair is pressed onto the heating surface.
  • the design of the hair straightener is often also symmetrical, ie two opposing heating surfaces are provided, which also serve as a pressing surface for the other heating surface. Hair is passed through the straightener in one direction.
  • a first sensor can now be provided in the front area and a second sensor in the rear area. This sensor then measures one at a time on the heating surface Temperature. This leads to temperature differences, which also depend on the type and condition of the hair being carried out.
  • the present invention also relates to a method for thermal hair treatment, in which the treatment temperature is regulated automatically depending on the condition of the hair.
  • a method for thermal hair treatment in which the treatment temperature is regulated automatically depending on the condition of the hair.
  • Such a method can in particular be one in which a hair straightener is used as a device for hair treatment.
  • the initial contact of the hair treatment device with the hair takes place at a preset temperature.
  • This preset temperature is then changed depending on the temperature difference measured between the first and second sensor.
  • the preset temperature is increased if a large temperature difference is measured between the two sensors.
  • the preset temperature is reduced if a small temperature difference is measured between the two sensors.
  • the invention can be used with a curling iron as a hair treatment device.
  • a suitable curling iron is in Fig. 1 pictured. It has a handle part 110, which is equipped with a viewing window 112. This viewing window 112 serves to make the fill level of a gas cartridge visible.
  • the present invention can thus also be used with devices that are not powered by electricity, namely, for example, gas-powered devices that generate heating power, for example, by catalytic gas combustion.
  • the device has a switch 120, which serves as an on / off switch. In principle, it is also conceivable that the switch allows the selection of more than a predetermined starting temperature.
  • the device also has a hair treatment unit, which comprises a cylinder rod 132 and a clip 134.
  • the clamp 134 can be released from the cylinder rod 132 and hair to be curled is inserted between the cylinder rod 132 and the clamp 134.
  • the attachment of at least two sensors at different locations on the curling iron 100 can be considered. It is particularly advantageous to use the area 140 for attaching a first sensor and additionally the area 142 for attaching a second sensor. The sensors are then to the left and right of clip 134. As a result, they are in contact with hair that is being fed to the curling iron and also with hair that is just leaving the area of the curling iron.
  • Fig. 2 shows a hair straightener, which is another hair treatment device according to the invention.
  • the hair straightener 200 has a handle area 210 and a hair treatment area 230.
  • the handle area comprises a first handle area 212 and a second handle area 214, which are each assigned to the arms of the hair straightener 200.
  • the two arms are connected by a connecting joint 216.
  • a cable 218 is provided at the end of the hair straightener 200. It is therefore an electrically operated hair treatment device.
  • a temperature controller 220 is also provided. In the form of the rotary wheel shown, it is easy to preselect a desired starting temperature.
  • the temperature controller 220 can also serve as a switch.
  • the device can be switched on or off, for example, by connecting the cable 218 to the mains and by removing the cable from the mains.
  • the hair treatment section 230 comprises the hair treatment section of the first arm 232 and the hair treatment section of the second arm 234.
