• the appliance 1 to which the invention applies is a straightening iron, having two arms 2, 3 that are connected by an articulation 4 and carry heating elements 5, 6 on opposing faces of the arms. These elements 5 and 6 make up straightening plates.
• This appliance 1 takes a refill 10 which is fixed to one of the arms, next to one of the heating elements, in this case the upper arm 2 and the heating element 5.
• the refill 10 shown on its own in figure 4, has a body 11 which contains a product to be applied, in this case a cosmetic product to be applied to the hair.
• the refill 10 also has an application means 13 for applying this product, such as a felt, for example, which comes into contact with the hair while the appliance is being used.
• the refill 10 has a means 12 for fixing it to a receiving structure of the appliance, only a part of which has been shown in figure 2.
• the product contained in the refill can be applied to the hair as the latter passes between the arms.
• the means for fixing the refill to the appliance has two profile elements 14 and 15, which are inserted into guideway elements provided on the corresponding arm.
• the appliance has for example three guideway elements 17, 18 and 19 that are intended to cooperate with the upper profile element 15, and two guideway elements 20 and 21 that are intended to cooperate with the lower profile element 14, when the refill 10 is fitted on the appliance.
• the refill 10 may comprise a hook 23 extending from the rear end of one of the two profile elements 14 or 15 and intended to cooperate with a clip 24 in order to hold the refill in position, this hook 23 being for example snap-fastened in the clip 24 at the end of its insertion into the appliance, and being able to be withdrawn therefrom by a mechanism of the push/pull type or the like.
• the appliance has an electrical contactor 26 which is actuated by the refill 20 when the latter is present, and which makes it possible to indicate whether the refill is present.
• This contactor comprises a lever 26a against which a seal 26b may press, said seal itself being actuated by a pusher 26c.
• the appliance 1 has a blocking member 30, the role of which is to cooperate with a mobile element 33 of the refill 10 that serves as a memory of use.
• the blocking member 30 is returned elastically by a leaf spring 31 in this example and has, at the front, an edge 34 substantially perpendicular to the plane of the wall 35 to which the guideway elements are attached, and, at the rear, a less steep edge 37.
• the blocking member 30 is disposed for example through a slot 36 in the wall 35 and can retract when the element 33 passes in the direction of removal of the refill.
• the mobile element 33 is in the form of a pin which is mounted as a friction fit in a corresponding housing 42 in the upper profile element 15, as can be seen in figures 5 A and 5B.
• the element 33 does not project into the space 43 defined between the two profile elements 14 and 15 before the refill is used for the first time, as can be seen in figures 5B and 6A, notably.
• the appliance 1 has a relief designed to move the element 33 when the refill 10 is fitted on the appliance for the first time.
• this relief is formed by a ramp 45 of the guideway element 18 situated at the rear edge 37 of the blocking member 30.
• the element 33 thus projects into the space 43 between the profile elements 14 and 15, as illustrated in figure 5D.
• the blocking member 30 engages between the profile elements 14 and 15 when the refill 10 is fitted on the appliance. Thus, during the insertion of the refill 10, the blocking member 30 sweeps over the zone into which the element 33 extends once in the active position as shown in figures 5C and 5D.
• the slope of the rear edge 37 of the blocking member 30 is chosen such that the element 33 can deform the blocking member 30 during the removal of the refill in order to retract and pass over said blocking member 30.
• the pusher 26c which acts on the contactor 26 is situated upstream of the blocking member 30 with regard to the direction of introduction of the refill 10 into the appliance 1. Thus, the contactor 26 is actuated even before the blocking member 30 exerts its possible action of blocking the insertion of the cartridge.
• the assembly formed by the refill and the appliance operates as follows.
• the ramp 45 causes the element 33 to move from the position of figures 5A and 5B to that of figures 5C and 5D.
• This change in position takes place when the element 33 has already passed over the front edge 34 of the blocking member 30, on account of the offset between this edge 34 and the ramp 45 in the direction of insertion of the refill 10.
• the blocking member 30 therefore does not impede the fitting of the refill 10.
• the element 33 can pass over the blocking member 30 on account of the slope of the rear edge 37 thereof.
• the element 33 that serves as a memory of use can be embodied in various other ways and other than with the aid of a pin that is able to move with friction in a housing, as has just been described with reference to figures 1 to 6B.
• the element 33 in the form of a hook, comprising an end part 53 which catches in a housing 51 of the lower profile element 14 and a connecting part 52 which connects the end part 53 to the body of the refill.
• This embodiment makes it possible to form the element 33 by molding it in one piece with the profile elements 14 and 15 and the body of the refill 10.
• the ramp 45 of the appliance presses against the element 33, for example at the elbow formed between the parts 52 and 53 of the element 33, and the part 53 can be snap-fastened in the housing 51, as illustrated in figure 9B.
• Figure 9A shows that, in the initial position, which corresponds to that of figures
• the end part 53 is situated above the path of the blocking member 30 and therefore does not impede the fitting of the refill. In the active position, as illustrated in figure 9B, once the end part 53 has been snap-fastened in the housing 51, it can butt against the blocking element 30.
• the refill may also comprise, extending from the rear end of the profile element 14 or 15 that does not bear the hook 23, a positioning finger 80 making it easier for the profile elements 14 and 15 to be positioned with respect to the guideway elements 17 to 19 of the appliance during insertion of the refill in the insertion guide.
• This positioning finger 80 may have a chamfer 82 on its opposite edge to the hook 23. Such a chamfer 82 makes positioning even easier.
• the finger 80 may also, where it meets the profile element 14, form a discontinuity 84 on the same side as the hook 23, the finger 80 being smaller in width than the profile element 14 from which it extends.
• the refill 10 has, between the finger 80 and the hook 23, a space 86 which is wider than the space between the two profile elements
• Such a space 86 makes it easier to attach the hook 23 to the clip of the corresponding appliance.
• the hook 23 may extend further to the rear than the positioning finger 80 so that the latter does not impede the snap-fastening of the hook 23 onto the clip 24.
• the refill 10 may be replaced by an article, as depicted for example in figure 13, having the same structure as the refill 10 except for the element serving as a memory of use and for the cosmetic product, which it does not have.
• the article acts on the detection element 26 in the same way as the refill 10 would.
• the article may have a different structure than the refill.
• the article does not have the felt, the housing normally provided for the latter on refills being open or closed.
• the article may be a part that does not come into contact with the hair or the pressing element when the arms are closed but acts on the detection element in order to be detected as a refill.
• the article may be made from a different material than the refill.
• the appliance 1 has an electronic circuit 100, shown schematically in figure 10, which has an electronic memory 101, for example of the EEPROM type.
• This electronic circuit 100 is connected to the contactor 26 which is actuated while the refill 10 is being fitted on the appliance. It is also connected to at least one electrical resistor 102 for steam production, to one or more electrical resistors 103 for heating the elements 5, 6, and to one or more temperature sensors 104 that make it possible, for example, to know the temperature of the plates.
• a switch 105 for example of the reed switch type, makes it possible to know the closed or open state of the appliance.
• the switch 105 is disposed for example on one of the arms and a magnet is disposed on the other of the arms so as to change the state of the switch 105 when the two arms 2, 3 are in the closed position.
• the switch 105 makes it possible to inform the electronic circuit 100 of the number of closures of the arms.
• the electronic circuit 100 is designed to be connected by a power cable 106 to the AC mains, for example the 110 V or 240 V mains.
• the electronic circuit 100 may be in the form of one or more boards, some of which may be disposed in the handpiece and others of which may be disposed in the base station when the appliance has such a base station, which serves for steam production by containing for example a water reservoir and a pump.
• the electronic circuit 100 has at least one component such as a microcontroller, programmed to execute an algorithm controlling the operation of the appliance, preferably in accordance with the diagram in figure 11.
• the electronic circuit 100 is powered when the cable 106 is connected to the electric mains and can detect fitting of the refill when the appliance is switched off.
• the step 201 of connecting the cable 106 of the appliance to the mains makes it possible, in a step 202, to detect, by virtue of a contactor 26, the possible insertion of the refill 10 prior to the appliance 1 being switched on, in step 203, by pressing a corresponding button.
• step 204 a variable ILS nbr representative of the number of closures of the arms is initialized in step 204, even though the appliance 1 has not yet been started up.
• step 203 a detection of the presence of the refill is carried out in step 205. If the refill has not been fitted, which corresponds to the branch 206 in the diagram, the variable ILS nbr is initialized in step 207 and the operation of the appliance 1 is effected in the downgraded mode, this being schematically indicated by the block 208 in figure 10.
• the temperature is predefined so as to be non-adjustable, for example set to the value of 180°C, the generation of steam is prevented and cannot be activated, and the corresponding state is signaled to the user, for example by the flashing of an LED or the emission of an audible signal.
• the appliance 1 remains in this downgraded mode until a refill is possibly inserted in step 209, in which case the appliance operates in a non-downgraded mode, depicted by the block 210 in figure 10, in which the temperature can be adjusted by the user, starting from a default value stored in the memory, which corresponds to the last use value in the non-downgraded mode.
• the steam generator is activated and the corresponding state is signaled to the user for example by the abovementioned LED being illuminated in a non- flashing manner.
• the electronic circuit 100 detects the closure of the arms 2, 3 on the locks treated in step 211, so as to increment the variable ILS nbr by a quantity representative of the number of closures.
• the variable ILS nbr is incremented by 5 units.
• a check is made as to whether the variable ILS nbr is less than a predefined threshold nl, where nl 160, for example. If the variable ILS nbr is less than nl, the cosmetic composition in the refill is considered not to have been used up and the appliance 1 can continue to operate in the non-downgraded mode, as is indicated schematically by the branch 213 in figure 1 1. If the value of the variable ILS nbr becomes greater than or equal to the threshold nl, as is depicted by the branch 215, the appliance passes back into the downgraded mode, corresponding to the block 208 in figure 11. The setpoint heating temperature of the plates thus returns to the predefined value of the downgraded mode, the operation of the steam generator is interrupted, and the corresponding state is signaled by the display of the LED, which flashes.
• the stored value of the variable ILS nbr is read in step 218. If this value is less than the threshold nl, as is depicted by the branch 219 in figure 10, the appliance maintains the non-downgraded mode depicted by the block 210. If the stored value of the variable ILS nbr is greater than or equal to the threshold nl, the appliance passes into the downgraded mode, as is depicted by the branch 221 and the block 208.
• variable ILS nbr is reinitialized in step 224 and the appliance 1 passes into the downgraded mode.
• the appliance 1 is designed, in the event of a prolonged period of non-use, that is to say without closures of the arms 2, 3 being detected, to pass into sleep mode in step 230, until the on button is pressed in step 210.
• the block 231 schematically indicates the case in which the appliance 1 is disconnected, in which case, when it is reconnected, the algorithm in figure 10 returns to step 201 described above.
• step 205 if the appliance 1 is started in step 203 with the refill 10 already fitted, this corresponding to the branch 234 in figure 10, the value of the variable ILS nbr is read in step 235 and this value is compared with a second threshold n2, which is different from the threshold nl and notably less than the latter.
• the threshold n2 is equal to 20, for example. If the value of the variable ILS nbr is greater than or equal to n2, the appliance passes into the downgraded mode in step 208.
• the appliance can operate in the non-downgraded mode, corresponding to the branch 237 and the block 210 in figure 11.
• the invention is not limited to the algorithm illustrated.
• a clock 110 shown by way of dotted lines in figure 10, preferably provided with a battery for saving the data in a clock memory.
• the downgraded mode corresponds to operation without the steam generator and at a predefined temperature of the heating plates.
• the downgraded mode is different and corresponds for example to operation still with a possibility of adjusting the temperature of the heating plates, this preferably being more limited than in the presence of steam.
• the appliance is designed such that it can identify the nature of the fitted refill, by virtue for example of one or more reliefs on the refill which encode information which is read by one or more corresponding contactors present on the appliance.
• the threshold values notably the first threshold nl, depending on the nature of the refill, for example in order to take into account the fact that the cosmetic composition is used up differently from one refill to another depending on the nature thereof.
• the element 33 is produced for example by being molded together with the adjacent profile element, being connected thereto by one or more severable bridges of material. Once in the active position, the element 33 can be held only by friction or, alternatively, by snap-fastening in the profile element opposite.
• the invention has been illustrated in connection with a refill fitted on the appliance by a sliding movement, the invention also applies to refills that are fitted by a movement other than just a sliding movement, for example a rotational movement or a more complex movement including translational and rotational components, for example.
• the blocking member 30 may also be produced as a plastics part that is articulated about a pivot axis and is returned to its initial position by a coil spring.
• the shape of the profile of the cartridge may be different from the overall T shape illustrated, and the element 33 can be moved in some other way than in the spatial direction defined between the two profile elements; for example, it can be moved in a direction parallel to the stem of the T.
• the presence of the element 33 in the active position can be detected automatically if an attempt is made to fit the cartridge on the appliance, by virtue for example of a mechanical or optical sensor, in order to signal the reason for which the refill cannot be fitted to the user, for example by a message being displayed on a screen or by an indicator light being illuminated.
