Description

DESCRIPTION

TITLE: Steam diffusion base for a household appliance

TECHNICAL AREA

This presentation concerns the field of household appliances. More specifically, this presentation concerns a household steam diffusion appliance.

STATE OF THE ART

Some household appliances use steam. Such devices may include a base which generates steam and which is connected to an accessory capable of projecting the steam generated by the base. Some accessories may be removable from the base, so that the appliance is suitable for different uses, such as ironing or steaming. However, changing accessories can be problematic because when uncoupling the accessory, whether intended or accidental, steam may escape from the base and/or electrical connectors may be exposed , which may jeopardize the user's safety. In addition, the connection area of the accessory to the base must remain waterproof when no accessory is connected to the base.

GENERAL PRESENTATION

One aim of this presentation is to offer a household appliance suitable for different types of use.

Another goal of this presentation is to improve the safety of a household appliance.

Another aim of this presentation is to propose a household appliance of economical and reliable construction, the use of which is simple and quick.

For this purpose, according to one aspect of the present presentation, a steam diffusion base is proposed for a household appliance, the steam diffusion base comprising: a casing comprising a face, a connection opening being provided through the face; a steam generator arranged inside the casing; a supply conduit connected to the steam generator and intended to distribute steam from the steam generator to the connection opening; and a shutter panel pivotally mounted between a deployed position in which the blanking panel seals the connection opening and a retracted position in which the blanking panel extends into the interior of the housing.

Providing that the blanking panel extends inside, not outside, the housing in the retracted position improves the seal of the vapor diffusion base because, when decoupling a diffusion accessory steam, steam is less likely to escape through the connection opening. In addition, this allows easier handling of the steam diffusion accessory, since the coupling of the latter to the steam diffusion base automatically causes the shutter panel to move from the deployed position to the retracted position, without the need to manipulate the shutter panel independently.

In the deployed position, the shutter panel can seal the connection opening tightly.

The diffusion base may further comprise a stopping member provided to retain the shutter panel in the deployed position.

The vapor diffusion base may further include a return member configured to bias the shutter panel toward the deployed position.

The casing may further comprise a support face intended to place the vapor diffusion base on a substantially flat surface, the face in which the connection opening is provided being able to be a lateral face of the casing extending substantially perpendicular to the support face.

The shutter panel may comprise a first portion intended to ensure the pivoting of the shutter panel and a second portion opposite the first portion, the second portion being free, in which, in the deployed position, the first portion can be more close to the support face as the second portion.

The vapor diffusion base may further comprise a first locking element intended to cooperate with a second locking element of a connection member so as to prevent removal of the connection member from the vapor diffusion base, the connection member being intended to be inserted into the connection opening in order to connect a steam diffusion accessory to the steam diffusion base to diffuse steam from the steam generator to the steam diffusion accessory .

A connection channel can extend from the connection opening towards the inside of the casing, be connected to the supply conduit and be provided to cooperate with a connection member provided to be introduced into the connection opening in order to connect a steam diffusion accessory at the steam diffusion base for diffusing steam from the steam generator to the steam diffusion accessory.

The casing may further comprise a support face intended to place the vapor diffusion base on a substantially flat surface, the face in which the connection opening is provided being able to be a lateral face of the casing extending substantially perpendicular to the support face and the connection channel can extend along a longitudinal axis substantially parallel to the support face.

The vapor diffusion base may further comprise a first locking element designed to cooperate with a second locking element of the connection member so as to prevent translation of the connection member relative to the vapor diffusion base. steam along the connection channel and the first locking element can be movable between a deployed position in which a blocking portion of the first locking element intended to cooperate with the second locking element extends inside the steam channel connection, and a retracted position in which the blocking portion extends outside the connection channel.

The first locking element may include an actuator adapted to be actuated by a user to unlock cooperation between the first locking element and the second locking element and release withdrawal of the connection member from the vapor diffusion base.

According to another aspect of the present presentation, a household appliance is proposed comprising: a steam diffusion base as previously described; a steam diffusion accessory; and a connection member adapted to be inserted into the connection opening to connect the steam diffusion accessory to the steam diffusion base to diffuse steam from the steam generator to the steam diffusion accessory .

The vapor diffusion base may further comprise a first locking element, the connection member comprising a second locking element adapted to cooperate with the first locking element when the connection member is inserted into the connection opening , so as to prevent removal of the connection member from the vapor diffusion base.

DETAILED DESCRIPTION

Appliance Figure 1 illustrates a household appliance 1, that is to say an appliance running on electricity and intended to meet domestic needs.

The household appliance 1 is capable of performing various functions such as the treatment of laundry, typically ironing and/or removing wrinkles from clothes, and/or cleaning surfaces, such as a window. To perform these functions, the household appliance 1 is configured to diffuse steam, preferably water vapor.

The household appliance 1 is portable, in that it is designed to be easily transported by a user.

The household appliance 1 comprises a steam diffusion base 2 and a steam diffusion accessory 3, 4, 5 removable relative to the steam diffusion base 2.

As illustrated in Figure 1 to Figure 7, the vapor diffusion base generally takes the shape of a box, of substantially frustoconical shape, although this is of course not limiting, any vapor diffusion base shape 2, such as a parallelepiped, which can be considered.

The vapor diffusion base 2 comprises a support face 200 intended to place the vapor diffusion base 2 on a substantially horizontal and flat surface, typically on the ground, and a plurality of lateral faces 201, 202 extending from the support face 200.

In this presentation, the terms "horizontal" and "vertical" are used with reference to the situation of use of the household appliance 1 in which the support face 200 rests flat on a plane, an element being horizontal when it extends substantially parallel to the plane and vertical when it extends substantially orthogonal to the plane. In the same way, the terms "lower" (or "bottom") and "upper" (or "high") refer, respectively, to an area of the household appliance closer, or further away, from the plane on which rests the support face 200.

Furthermore, the vapor diffusion base 2 is advantageously portable and can, to do this, comprise a carrying handle 22 positioned at an upper end of the vapor diffusion base 2, that is to say an end which is opposite the support face 200, the transport handle 22 being provided for transporting the vapor diffusion base 2. The transport handle 22 can take any suitable shape and dimensions, or even be provided with components of grip 220, such as a surface having a higher roughness than the rest of the transport handle 22, the surface extending from the transport handle 22, and this to facilitate its grip by a user, typically by preventing the user's hand from slipping on the carrying handle 22.

At least one of the side faces 201, 202 of the vapor diffusion base 2 extends substantially perpendicular to the support face 200 and delimits a storage space 2010 provided to accommodate the vapor diffusion member 6 of the steam diffusion accessory 3, 4, 5, which steam diffusion member 6 is described in more detail below. By substantially perpendicularly, it is envisaged that an angle between the side face 201 and the support face 200 is between 80° and 100°. Thus, the steam diffusion base 2 offers a storage space 2010 in which the steam diffusion member 6 extends in a substantially vertical position, which facilitates the transport of the household appliance 1, particularly to the extent where the grip of the transport handle 22 of the steam diffusion base 2 is not hindered by the presence of the steam diffusion member 6. This side face 201 provided with the storage space 2010 can be formed in a plate 2012, advantageously comprising a material resistant to a temperature above 250° C. The plate 2012 is attached and fixed on the vapor diffusion base 2. As visible from Figure 2 to Figure 7, the space of storage 2010 is designed to accommodate the steam diffusion member 6, whether it is, moreover, connected or not to the steam diffusion base 2. The storage of the steam diffusion member 6 of the accessory of steam diffusion 3, 4, 5 on the basis of steam diffusion 2 can, for example, be used between two successive uses of the steam diffusion accessory 3, 4, 5 or to transport the household appliance 1 .

In order to secure the storage of the steam diffusion member 6 on the steam diffusion base 2, in particular during the transport of the household appliance 1, a retaining member 2011 is positioned at the level of the side face 201 of the steam diffusion base 2 which is provided with the storage space 2010, preferably at the upper end of the side face 201, that is to say the end which is opposite the support face 200 , in order to prevent the actuation of the retaining member 2011 from being hindered by the presence of the ground when the vapor diffusion base 2 is placed on the ground and the vapor diffusion member 6 is arranged on the ground. within the storage space 2010. The retaining member 2011 is in fact movable relative to the vapor diffusion base 2 between a retracted position, visible in Figure 1 and in Figure 2, in which the member retaining member 2011 authorizes the removal of the vapor diffusion member 6 from the storage space 2010, and an deployed position, illustrated from Figure 3 to Figure 7, in which the retaining member 2011 maintains the member steam diffusion 6 fixed within the storage space 2010. This allows simple and practical handling of the household appliance 1, which facilitates transport and storage. The retaining body 2011 is preferably movable in rotation relative to the vapor diffusion base 2 and advantageously takes the shape of an arch. It is in fact a mobility and a form of construction of the retaining member 2011 which are simple to use and inexpensive to manufacture. The retaining member 2011 can, in its deployed position, cooperate with different portions of the vapor diffusion accessory 3, 4, 5, as visible from Figure 3 to Figure 7, in particular with a hooking element 674 of the steam diffusion accessory 3, 4 described in more detail below.

Figure 7 further illustrates that the retaining member 2011 may comprise a suspension element 20111 extending from, preferably projecting, from the retaining member 2011 and intended to hold the vapor diffusion member 6 fixed in a suspension position, visible in Figure 5 and in Figure 6, when the retaining member 2011 is in the deployed position. This suspension element 20111 can advantageously take the form of a hook extending projecting from the retaining member 2011, preferably projecting from the free end of the arch 2011 when the arch 2011 is in the deployed position . The suspension element 20111 is particularly useful when the steam diffusion member 6 is temporarily arranged within the storage space 2010, typically between two successive uses of the steam diffusion accessory 3, 4, 5. In this regard, Figure 5 illustrates the steam diffusion member 6 of a steaming accessory 5 in a suspended position, while Figure 6 illustrates the steam diffusion member 6 of a steaming accessory. cleaning 4 in a hanging position. This makes handling the household appliance 1 easier.

To stabilize the steam diffusion member 6 of the steam diffusion accessory 4, 5 when it is in a suspension position, the retaining member 2011 may comprise, as visible in Figure 7, an element immobilizer 20112 configured to prevent transverse tilting, relative to the vertical, of the steam diffusion member 6 when it is in the suspension position. This immobilizing element 20112 can take the form of a rib extending projecting from the retaining member 2011, for example projecting from a surface of the retaining member 2011 intended to be facing the vapor diffusion base 2 when the retainer 2011 is in the retracted position. The immobilizing element 20112 can, in the deployed position of the retaining member 2011, cooperate with different portions of the vapor diffusion member 6 of the vapor diffusion accessory 3, 4, 5, as visible from Figure 2 to Figure 7, in particular with a guide element 675 of the vapor diffusion member 6 described in more detail below. Figure 2, Figure 3 and Figure 4 illustrate that the vapor diffusion base 2 can further comprise a stop 2013 extending from the side face 201 provided with the storage space 2010. The stop 2013 is designed to cooperate with a hooking recess 676 complementary to the steam diffusion accessory 3, 4, 5, described in more detail below, when the steam diffusion member 6 is arranged within the space storage space 2010. As visible more precisely in Figure 2, the stop 2013 can in particular be useful in order to arrange the steam diffusion member 6 temporarily within the storage space 2010, typically to rest the steam diffusion member 6 of an ironing accessory 3 on the steam diffusion base 2, between two successive uses. Also, the stop 2013 can in particular be useful for improving the hold of the steam diffusion member 6 within the storage space 2010, as illustrated in Figure 4, where the steam diffusion member 6 d a steaming accessory 5 is arranged inside the storage space 2010 and comprises a gripping handle 67, a portion of which cooperates with the retaining member 2011 and in which the hooking recess 676, formed in a steam diffusion head 61 of the steam diffusion member 6 of the steaming accessory 5, cooperates with the stop 2013. Advantageously, the stop 2013 takes the form of an appendage extending projecting from the face side 201 provided with the storage space 2010, as notably visible in Figure 4. In addition, the stop 2013 is positioned closer to the support face 200 than the retaining member 2011. In other words, the retaining member 2011 extends at a first distance from the support face 200, and the stop 2013 extends at a second distance from the support face 200, the second distance being less than the first distance. In this way, the steam diffusion member 6 has two attachment points to be held within the storage space 2010, which secures the transport of the household appliance 1.

Figure 1 further illustrates that the vapor diffusion base 2 can comprise a holding member 251 extending from the vapor diffusion base 2, and advantageously taking the form of a flexible tongue provided with through openings intended to cooperate with a holding pin 252 extending projecting from the steam diffusion base 2. The holding member 251 is intended to hook a cord 7 of the steam diffusion accessory 3, 4, 5, described in more detail below, in particular when the steam diffusion member 6 is arranged within the storage space 2010.

The vapor diffusion base 2 further comprises a casing 20 forming an envelope allowing waterproof protection against liquid splashes of the various components of the vapor diffusion base 2. The casing 20 may comprise any suitable material, such as plastic or metal. If applicable, the 2012 plate inside which is provided the storage space 2010 is reported and fixed on the casing 20. Otherwise, the casing 20 can include the side face 201 within which the storage space 2010 is provided. In the same way, the support face 200 can be formed by one of the faces of the casing 20 or, as visible in Figure 1, be at least partly formed by the external surface of pads 2000 extending projecting from the casing 20, being attached and fixed on the casing 20, or in one piece with the casing 20. Also, the transport handle 22 of the vapor diffusion base 2 can extend projecting from the upper end of the casing 20, that is to say opposite to the support face 200, being in one piece with the casing 20 or attached and fixed to the casing 20.

The steam diffusion base 2 is intended to supply steam to a steam diffusion accessory 3, 4, 5.

To do this, as visible in Figure 8, the steam diffusion base 2 comprises a steam generator 21, arranged inside the casing 20. The steam generator 21 can have various structures and typically comprise a tank 210 for the production of steam under pressure, the tank 210 being supplied with liquid, preferably water, via a tank 211, typically removable relative to the steam diffusion base 2. The tank 210 may include steel, typically stainless steel, and be equipped with an electric heating resistance to produce steam under pressure. The liquid can pass from the reservoir 211 to the tank 210 via a supply circuit 212 comprising a pump 213, typically a high pressure electromagnetic pump 213.

As illustrated in Figure 9, in Figure 10 and in Figure 11, the side face 202 of the vapor diffusion base 2 is defined by a face of the casing 20 which comprises the face 202 through which is provided an opening of connection 2021. The connection opening 2021 is designed to cooperate with a connection member 8 of the steam diffusion accessory 3, 4, 5 in a removable manner, as in particular visible in Figure 3, in Figure 10 and in Figure 11, in which the connection member 8 is introduced into the connection opening 2021 in order to connect the steam diffusion accessory 3, 4, 5 to the steam diffusion base 2 to diffuse steam from the steam generator 21 towards the steam diffusion accessory 3, 4, 5, or removed from the connection opening 2021 to uncouple the steam diffusion accessory 3, 4, 5 from the steam diffusion base 2 .

To do this, a supply conduit 214 is advantageously connected to the steam generator 21 and is intended to diffuse steam from the steam generator 21 towards the connection opening 2021. The steam diffusion base 2 can, in this regard, comprise a solenoid valve 215 arranged at one end of the tank 210 and the operation of which controls the diffusion of steam from the tank 210 towards the supply conduit 214.

In addition, as visible in Figure 9, in Figure 10 and in Figure 11, a connection channel 2022 can extend from the connection opening 2021 towards the interior of the casing 20, be connected to the conduit power supply 214 and be provided to cooperate with the connection member 8. On the side of the connection channel 2022 opposite the connection opening 2021, connection elements 2023 capable of, on the one hand, connecting an end piece 75 can be arranged. of a steam diffusion conduit 74 housed in the connection member 8 to the supply conduit 214 and, on the other hand, the ends of electrical wires 730 housed in the connection member 8, to a source of power supply (not shown) and/or electronic components, such as an electronic card 232 described in more detail below, arranged inside the casing 20. Thus, the power supply conduit 214 has a first end 2141 connected to the steam generator 21 and a second end 2142 opening into the connection channel 2022 and capable of being connected to the end piece 75. Advantageously, the connection channel 2022 extends along a longitudinal axis X1 -X1 substantially parallel to the support face 200, which facilitates the introduction of the connection member 8 through the connection opening 2021.

In order to prevent steam from accidentally escaping from the steam diffusion base 2, through the connection opening 2021, while the steam diffusion accessory 3, 4, 5 is not connected to the base, but also to prevent liquid from entering through the connection opening 2021 inside the vapor diffusion base 2, a shutter panel 241 is pivotally mounted on the vapor diffusion base 2 between a deployed position in which the panel closes the connection opening 2021 and a retracted position in which the panel extends inside the casing 20. The pivoting mounting can, for example, be arranged on the casing 20 or inside the casing 20, typically on the wall delimiting the connection channel 2022. In this regard, in the retracted position, the shutter panel 241 can advantageously disappear inside the connection channel 2022 The transition from the deployed position to the retracted position is generally caused by the introduction of the connection member 8 inside the connection opening 2021. Provide that, in the retracted position, the shutter panel. 241 extends inside, and not outside, the casing 20, offers additional security in the event of accidental tearing of the connection member 8. Indeed, when removing the connection member 8 of the connection opening 2021, the shutter panel 241 moves from the retracted position to the deployed position and, as this transition progresses, the possibility of steam escaping through the opening connection 2021 decreases. Furthermore, Figure 9 illustrates that the shutter panel 241 comprises a first portion 2411 provided to ensure the pivoting of the shutter panel 241 and a second portion 2412 opposite the first portion 2411, the second portion 2412 being free. In the deployed position, the first portion 2411 is advantageously closer to the support face 200 than the second portion 2412. In other words, the panel recedes inside the casing 20 towards the support face 200 and not towards the carrying handle 22, which facilitates the introduction of the connection member 8 into the connection opening 2021, because the resistance offered by the shutter panel 241 is lower. This is however not limiting, since it could well be envisaged that the panel disappears inside the casing 20 so that the second portion 2412 moves away from the support face 200. The latter configuration can in particular be used when the passage from the retracted position to the deployed position of the shutter panel 241 is not controlled by a return member 242, described in more detail below, but simply by gravity.

Advantageously, in the deployed position, the shutter panel 241 seals the connection opening 2021 in a sealed manner, which ensures that the steam produced within the steam diffusion base 2 remains confined to the interior of casing 20.

Figure 9 illustrates the presence of an advantageous stopping member 243 designed to retain the shutter panel 241 in the deployed position. In this way, the panel does not risk accidentally extending outside the casing 20, in the deployed position, which would call into question the sealing of the vapor diffusion base 2. Preferably, the member stop 243 is formed by a rib extending projecting inside the connection channel 2022 and positioned at the level of the connection opening 2021.

Furthermore, the vapor diffusion base 2 may comprise a return member 242 configured to urge the shutter panel 241 towards the deployed position and against the action of which the connection member 8 acts by being introduced inside. of the opening of connection 2021. The return member 242 acts as a safety device in order to guarantee that, in the absence of stress by the connection member 8, the vapor diffusion base 2 remains substantially sealed against any escape of steam by the connection opening 2021, the shutter panel 241 being held in the deployed position.

In addition, Figure 9 and Figure 11 illustrate that the vapor diffusion base 2 can comprise a first locking element 261 intended to cooperate with a second locking element 8220 of the connection member 8, described in more detail below. -after, so as to prevent removal of the connection member 8 from the vapor diffusion base 2, typically by preventing a translation of the connection member 8 relative to the base along the longitudinal axis X1 -X1 of the connection channel 2022. The cooperation of the first locking element 261 with the second locking element 8220 also offers a guarantee of correct connection of the connection member 8 with the steam diffusion base 2, typically by offering a haptic sensation, such as a click, for the user who manipulates the household appliance 1. The first element of locking 261 is preferably movable between an deployed position in which a blocking portion 2610 of the first locking element 261 intended to cooperate with the second locking element 8220 extends inside the connection channel 2022, and a retracted position in which the blocking portion 2610 extends outside the connection channel 2022. The first locking element 261 is advantageously movable by pivoting relative to the vapor diffusion base 2, a return element 263 advantageously requesting the first locking element 261 towards the deployed position. Furthermore, the first locking element 261 may comprise an actuator 262 intended to be actuated by a user to move the first locking element 261 from the deployed position to the retracted position, and thus allow the withdrawal of the connection member 8 of the vapor diffusion base 2. Figure 9, Figure 10 and Figure 11 illustrate that at least one portion of the actuator 262 can extend towards the exterior of the casing 20 to facilitate its manipulation by the 'user.

Figure 8 illustrates that the wall delimiting the connection opening 2021 and on which the shutter panel 241 and the actuator 262 are mounted can be constituted by a part which is attached to the casing 20, which facilitates the manufacture of the steam diffusion base 2.

With reference to Figure 3, the steam diffusion base 2 is advantageously supplied with electrical energy via an electrical cable 271, connected to the base, and intended to be connected to a domestic electrical network. To facilitate the transport and storage of the household appliance 1, the steam diffusion base 2 can be provided with a reel 272 on which the electrical cable 271 is mounted. The reel 272 can be passive, as illustrated in Figure 3, that is to say consist only of a hook around which the cable can be wound, or, in a manner known per se, be active, with a device making it possible to automatically wind the cable in a cavity provided for this purpose in the steam diffusion base 2. The electrical supply of the steam diffusion base 2 via the electrical cable 271 makes it possible in particular the operation of the electric heating resistance of the tank 210, of the pump 213 of the power supply circuit 212, of the electronic card 232 and/or of the steam diffusion member 6, as described in more detail below. Besides, the steam diffusion base 2 can advantageously be equipped with a switch (not shown) to control the switching on or off of the household appliance 1.

The vapor diffusion base 2 may further comprise a processor, typically integrated within the electronic card 232 visible in Figure 9, which is configured to control operation of the vapor diffusion base 2 and to operate thanks to the power supply to the steam diffusion base 2, via the electrical cable 271.

For example, the processor can control the operation of the pump 213 of the supply circuit 212 connecting the tank 210 to the tank 211 of the steam generator 21, or even the opening of the solenoid valve which controls the diffusion of steam from the generator of steam 21 towards the supply conduit 214. The control of the solenoid valve can typically be controlled via a switch, located on the steam diffusion base 2, or formed by a trigger 671 placed on the steam diffusion accessory 3, 4, 5, as described in more detail below.

Furthermore, the processor can modify the temperature and/or pressure within the steam generator 21, and more precisely the tank 210, typically by controlling the behavior of the electrical heating resistance. The processor can also advantageously control different power parameters of the steam diffusion accessory 3, 4, 5 by the steam diffusion base 2 and in particular the steam flow rate, the steam flow speed and/or the supply of electrical current to the steam diffusion accessory 3, 4, 5. Regulating the electrical current supplying the steam diffusion accessory 3, 4, 5 can in particular be useful when the diffusion accessory steam is an accessory for ironing, typically is an iron 3, because this electrical current supply controls the temperature of the heating soleplate 65 of the iron 3, which can, in this regard, be equipped with a thermostat , but also when the steam diffusion accessory is a steaming accessory 5 which can also advantageously comprise a heating element operating on electrical energy. From then on, the processor is able to control the temperature of the heated soleplate 65, taking into account in particular the effects of thermal inertia. The processor can modify the temperature within the steam generator 21 according to a time sequence comprising temperature stages, in order to prevent excessive steam flow rates from being suddenly released towards the steam diffusion accessory 3, 4, 5. Moreover, by modifying the temperature within the steam generator 21, the processor is configured to modify the flow rate of steam to be diffused from the steam diffusion base 2 to the steam diffusion accessory 3, 4 , 5. Changing the steam flow rate to be diffused from the steam diffusion base 2 to the steam diffusion accessory 3, 4, 5 can be critical depending on the steam diffusion accessory 3, 4, 5 which is connected at the vapor diffusion base 2. This is why, the processor is preferably configured to place this flow rate within one of three different flow ranges, in which a first of the three flow ranges extends from 30 g /min to 55 g/min, which corresponds to the flow rates consumed by a cleaning accessory 4, a second of the three flow ranges extends from 120 g/min to 180 g/min, which corresponds to the flow rates consumed by a cleaning accessory ironing 3, and a third of the three flow rate ranges extends from 120 g/min to 170 g/min, which corresponds to the flow rates consumed by a steaming accessory 5. Advantageously, this adjustment of the flow rate can also be carried out at the using a restriction element 76, described in more detail below.

Thanks to the processor, it is possible to adapt the operation of the steam diffusion base 2 as a function of the steam diffusion accessory 3, 4, 5 which is connected to the steam diffusion base 2. To do this , the vapor diffusion base 2 comprises a sensor (not shown), typically arranged inside the casing 20, for example on the side of the connection channel 2022 opposite the connection opening 2021. The sensor is configured to measure a value of the electrical resistance of an electronic component 82251 housed within the connection member 8, described in more detail below. This measurement is implemented by the sensor once the steam diffusion accessory 3, 4, 5 is connected to the steam diffusion base 2 by means of the connection member 8. The processor is then configured to control the operation of the steam diffusion base 2 as a function of the value of the electrical resistance recorded by the sensor. In this regard, the sensor is adapted to communicate with the processor, either by wired means or remotely, typically via an electromagnetic network of the Wifi or Bluetooth type. Thus, in a simple, inexpensive, safe and quick way, it is possible to use steam diffusion accessories of several types with the same steam diffusion base 2.

Steam diffusion accessory

As visible in Figure 1, the steam diffusion accessory 3, 4, 5 comprises a steam diffusion member 6, a cord 7 and a connection member 8.

Steam diffusion device The steam diffusion member 6 is designed to project the steam produced by the steam diffusion base 2. In this regard, the steam passes through the cord 7, once it is connected to the steam diffusion base 2 by means of the connection member 8.

To adapt the flow of steam produced within the steam diffusion base 2 to the steam diffusion members 6 of the steam diffusion accessory 3, 4, 5, a restriction element 76 can be provided in the member connection 8 of the steam diffusion accessory 3, 4, 5, as described in more detail below. Where appropriate, the household appliance 1 may comprise a plurality of steam diffusion accessories 3, 4, 5, at least one of which is provided with such a restriction element 76 and at least one other does not, or more precisely which its tip 75, described in more detail below, is devoid of.

The steam diffusion accessory 3, 4, 5 is removable insofar as the connection member 8 is intended to be connected or disconnected from the steam diffusion base 2. This is particularly useful for adapting the use of the household appliance 1 with the various desired uses. Indeed, the use of a steam diffusion accessory 3, 4, 5 is determined by its steam diffusion member 6.

Generally speaking, the steam diffusion member 6 comprises a gripping handle 67 from which a steam diffusion head 61 extends. The gripping handle 67 can be in one piece with the steam diffusion head 61, or else be assembled and fixed to the steam diffusion head 61 by means of any suitable fixing element, for example screws.

The gripping handle 67 allows manipulation of the steam diffusion member 6 by a user, but also the transport of the steam diffusion accessory 3, 4, 5 if necessary. In this regard, the gripping handle 67 can be provided with gripping elements 6770, visible in Figure 5 and Figure 6, but also in Figure 13, such as a surface having a higher roughness than the rest of the gripping handle 67, the surface extending from the gripping handle 67, and this to facilitate its gripping by a user, typically by preventing the user's hand from slipping on the gripping handle 67.

The gripping handle 67 can connect the cord 7 to the steam diffusion head 61 and, in certain cases, as for the cleaning accessory 4 and the steaming accessory 5, allows the diffusion of steam from the cord 7 towards the steam diffusion head 61. This is in fact not limiting since the cord 7 can be connected to any portion of the organ steam diffusion 6 other than gripping handle 67, typically to the main body in the case of the iron 3.

In addition, the gripping handle 67 can be provided with a switch, typically a trigger 671, controlling the opening of the solenoid valve of the steam diffusion base 2, to authorize diffusion of steam from the steam generator 21 towards the steam diffusion member 6, through the cord 7. The trigger 671 is movably mounted, for example by pivoting, on the gripping handle 67 and is connected to electronic components making it possible to transmit a request from the trigger 671 by a user, via electrical wires 730 extending inside the cord 7, to the processor of the vapor diffusion base 2. If necessary, the trigger 671 can be monostable, it is that is to say, it can be brought manually into a depressed position activating the opening of the solenoid valve and automatically return to a rest position when no pressure is exerted on it.

As particularly visible in Figure 7, the gripping handle 67 can be provided with a hooking element 674 and a guide element 675 which are, respectively, intended to cooperate with the retaining member 2011 and the immobilization element 20112 arranged at the level of the storage space 2010 of the vapor diffusion base 2. The hooking element 674 generally takes the form of a loop extending from the end of the gripping handle 67 opposite the steam diffusion head 61, which makes it possible to avoid any collision between the steam diffusion head 61 and the retaining member 2011, and facilitates the storage of the steam diffusion member 6 on the basis of vapor diffusion 2. In addition, the guide element 675 can take the form of a groove formed within the loop to cooperate with the rib of the immobilizing element 20112. It is acts in fact simple, safe and inexpensive to manufacture. Figure 5 and Figure 6 typically illustrate a vapor diffusion member 6 in the suspension position in which the retaining member 2011 and the immobilizing element 20112 of the vapor diffusion base 2 cooperate, respectively, with the hooking element 674 and the immobilizing element 20112 of the gripping handle 67 of the steam diffusion member 6.

The steam diffusion head 61 is intended to project the steam produced by the steam diffusion base 2, its structure being adapted to the desired use, for example the treatment of linen by ironing or steaming, or the cleaning of surfaces . Figure 1, Figure 4, Figure 5 illustrate a steam diffusion member 6 When The steam diffusion accessory is a steaming accessory 5 intended for steaming laundry. Figure 2, Figure 3, Figure 12 and Figure 13 illustrate an organ steam diffusion 6 when the steam diffusion accessory is an iron 3. Figure 6, Figure 14, Figure 15, Figure 16, Figure 17, Figure 18, Figure 19 and Figure 20 illustrate a steam diffusion member 6 when the steam diffusion accessory is a surface cleaning accessory 4.

If necessary, as notably visible in Figure 2 and Figure 4, the steam diffusion head 61 can be provided with a hooking recess 676 complementary to the stop 2013 of the steam diffusion base 2. Figure 4 illustrates that, in the case of a steam diffusion member 6 of a steaming accessory 5, the hooking recess 676 takes the form of a groove made at the surface of the steam diffusion head. steam 61 which is opposite the gripping handle 67, the storage space 2010 providing a sub-space 20100, at the level of the lower end of the storage space 2010, that is to say the end closest to the support face 200 of the steam diffusion base 2, adapted to accommodate a portion of the steam diffusion head 61 in order to limit its bulk.

Figure 2, Figure 3, Figure 12 and Figure 13 illustrate that a steam diffusion member 6 of an ironing accessory 3 comprises a main body forming a steam diffusion head 61, and a gripping handle 67 connected to the main body.

The steam diffusion head 61 comprises a heating soleplate 65 intended to come into contact with the laundry to be treated, typically a garment to be ironed. The heating soleplate 65 comprises a thermally conductive material, such as metal, and may further comprise a coating positioned at its surface intended to come into contact with the laundry, the coating being configured to improve sliding on the laundry and/or or avoid damaging the laundry. A plurality of steam diffusion orifices (not visible in Figure 12) is provided through the heating soleplate 65. In this regard, the steam diffusion head 61 comprises a diffusion circuit adapted to supply the steam diffusion orifices with steam produced within the steam diffusion base 2 and passing through the cord 7.

Figure 12 also illustrates that the steam diffusion head 61 comprises a housing 66 delimiting an internal cavity 660, the heating sole 65 being mounted on the steam diffusion head 61 so as to delimit, with the housing 66, a passage of communication 6600 between the internal cavity 660 and the exterior of the vapor diffusion head 61. The housing 66 is provided to protect the components of the vapor diffusion member 6. Typically, Figure 12 illustrates that a vapor diffusion member heating 6630, 6631, 661 can be arranged within the internal cavity 660 and be configured to heat the heating sole 65. The heating member 6630, 6631, 661 is embedded in the sole 65 and comprises a metallic tubular element 6630, typically made of copper-plated steel, defining the external wall of the heating member 6630, 6631, 661, and an electrically conductive element, typically taking the form of a resistive electric wire 661, extending inside the tubular element 6630. The tubular element 6630 is, moreover, filled with magnesia 6631 which ensures both the electrical insulation of the tubular element 6630 with respect to the resistive electric wire 661 and the good thermal conduction towards the sole 65. In addition, as visible in Figure 12, at least part of the resistive electrical wire 661 extends outside the tubular element 6630 and has a free end 6610 allowing its electrical connection to a power cable extending through the cord 7.

Figure 12 also illustrates the attachment recess 676 provided within the steam diffusion member 6, and more precisely the steam diffusion head 61, and intended to cooperate with the stop 2013 of the diffusion base steam 2. The hooking recess 676 is made at a portion of the steam diffusion head 61 intended to extend facing the ground when the steam diffusion member 6 is in the vertical position. This is however not limiting, since the attachment recess 676 could be provided at other portions of the steam diffusion head 61.

Furthermore, as visible in Figure 3, the portion of the vapor diffusion head 61 which is opposite the hooking recess 676 forms a retaining portion 610 adapted to cooperate with the retaining member 2011 of the base vapor diffusion 2. The shape of this retaining portion 610 is in fact intended to match the shape of an internal surface of the retaining member 2011 in the deployed position of the retaining member 2011, the blocking of the steam diffusion member 6 in a vertical position within the storage space 2010 resulting from the inclination, relative to the vertical, of the external surface of the steam diffusion head 61 at this portion of withholding 610.

As visible in Figure 13, the gripping handle 67 is hollow. In other words, the gripping handle 67 comprises a wall delimiting an internal cavity 678 which extends inside the gripping handle 67. The internal cavity 678 is in particular intended to house the mechanical and/or electronic elements making it possible to transmit the requests of the trigger 671 to the processor of the steam diffusion base 2, via the cord 7. This internal cavity 678 is closed by a cover 677 designed to cooperate with the wall delimiting the internal cavity 678. As visible in Figure 13, the cover 677 can be provided with hooking elements 6770 facilitating the gripping of the gripping handle 67 by a user.

Figure 13 also illustrates that, due in particular to the structural fragility which may result from the presence of the internal cavity 678 within the gripping handle 67, reinforcing ribs 673 can be provided, which extend inside the internal cavity 678 and connect together different portions of the wall delimiting the internal cavity 678 to reinforce the structure of the gripping handle 67. The reinforcing ribs 673 can also be used to maintain all or part of the mechanical and/or electronic elements making it possible to transmit the requests from the trigger 671 movably mounted on the gripping handle 67 to the processor of the vapor diffusion base 2.

When the iron 3 is arranged within the storage space 2010 while another steam diffusion accessory 4, 5 is connected to the steam diffusion base 2 and happens to be in operation, the steam can be projected onto the iron 3, condense, and penetrate it, which endangers its lifespan.

For example, liquid risks entering the internal cavity 660 of the steam diffusion head 61, through the communication passage 6600 between the internal cavity 660 and the exterior of the main body. This is why, as visible in Figure 12, it is in particular provided that an insulation sheath 662 surrounds at least a portion of the free part of the resistive electrical wire 661 extending outside the tubular element 6630. In this way, the free end 6610 of the resistive electric wire 661 is electrically isolated from the tubular element 6630. Thus, if liquid comes to circulate at the free end 6610 of the resistive electric wire 661, a drop of liquid does not risk establishing an electric arc between the free end 6610 and the tubular element 6630, made of conductive material, defining the external wall of the heating member 6630, 6631, 661. The insulation sheath 662 may comprise any suitable electrically insulating material, such as plastic. In addition, the insulation sheath 662 can have any shape and any dimensions suitable for insulating the resistive electric wire 661 and thus preventing the establishment of an electric arc with liquid accidentally circulating within the internal cavity 660.

In addition, an evacuation system can be provided configured to evacuate, by gravity, liquid from the internal cavity 660 towards the outside of the vapor diffusion head 61 When the vapor diffusion member 6 is arranged at the within the storage space 2010, or more generally when the steam diffusion member 6 is in a vertical position, that is to say in a position where the steam diffusion head 61 extends substantially perpendicular to the ground. This evacuation system offers additional safety by preventing a large quantity of liquid from accumulating in the vapor diffusion member 6 when the latter is stored in the storage space 2010.

Likewise, liquid can enter the internal cavity 678 of the gripping handle 67, for example through the gaps separating the cover 677 from the rest of the gripping handle 67, or through the gaps separating the trigger 671 from the rest of the handle. there gripping handle 67. Therefore, the lifespan of the moisture-sensitive components which extend within the internal cavity 678 is critical. This is why, as visible in Figure 13, the gripping handle 67 includes an evacuation system 672 configured to evacuate a liquid by gravity from the inside of the gripping handle 67 to the outside of the gripping handle 67 when the steam diffusion member 6 is arranged within the storage space 2010 or, more generally, when the steam diffusion member 6 is in a vertical position, that is to say in a position where the gripping handle 67 extends substantially perpendicular to the ground.

As visible in Figure 13, the evacuation system 672 of the gripping handle 67 may include various components. First of all, the evacuation system 672 of the gripping handle 67 may comprise at least one evacuation orifice 6720, preferably two evacuation orifices 6720, provided through an evacuation wall 6721 of the handle. grip 67 intended to extend opposite the support face 200 when the vapor diffusion member 6 is arranged within the storage space 2010. Liquid accumulated within the internal cavity 678 can thus advantageously be evacuate it as soon as the gripping handle 67 is positioned vertically. In addition, as also illustrated in Figure 13, at least one passage recess 6730 can be provided through at least one of the reinforcing ribs 673, so as to allow circulation of liquid through the reinforcing rib 673. Thus, liquid cannot accumulate in the different compartments formed within the internal cavity 678, between the reinforcing ribs 673.

Figure 14, Figure 15 and Figure 16 illustrate a steam diffusion member 6 of a cleaning accessory 4 intended for cleaning surfaces. However, what is described below with reference to these figures could be applied to a steam diffusion member 6 of a steaming accessory 5, such as that illustrated in Figure 1, Figure 4 and Figure 5.

Figure 15 and Figure 16 show that a steam transmission orifice 670 is provided at one end of the gripping handle 67, steam being capable of being diffused from the steam diffusion base 2 to to the steam transmission orifice 670 once the steam diffusion accessory 4 is connected to the steam diffusion base 2. In fact, the gripping handle 67 constitutes, in this case, an extension of the cord 7 to transmit the steam produced within the steam diffusion base 2 up to the steam diffusion head 61. The steam transmission orifice 670 is thus typically formed by the end of the steam diffusion conduit 74 extending within the cord 7 and described in more detail below, the gripping handle 67 being provided to maintain this end of the steam diffusion conduit 74. As visible more precisely from Figure 17 to Figure 20, the steam transmission orifice 670 is also provided at the level of the end of the gripping handle 67 which is opposite to the hooking element 674.

Figure 14, Figure 15 and Figure 16 further illustrate that the steam diffusion head 61, which extends from the end of the gripping handle 67 provided with the steam transmission orifice 670, comprises a base 62 and a steam diffusion part 64 advantageously constituted by different types of cleaning heads.

As particularly visible in Figure 15 and in Figure 16, the base 62 extends from the gripping handle 67 at the level of the end of the gripping handle 67 which is provided with the transmission orifice of steam 670.

Figure 14 shows that the base 62 further comprises a coupling face 6310, a main orifice 6311 and two secondary orifices 6312 being provided within the coupling face 6310, the secondary orifices 6312 being provided on either side of the main orifice 6311. In Figure 14, the main orifice 6311 and the secondary orifices 6312 are, moreover, preferably aligned along an axis transverse to the gripping handle 67, or even aligned in a plane transverse to the gripping handle 67. This is however not limiting, since the secondary orifices 6312 could also be aligned in a first plane transverse to the gripping handle 67, the main orifice 6311 extending in a second plane transverse to the handle, the second plane being further from the gripping handle 67 than the first plane. As described in more detail below, the relative positioning of the main orifice 6311 and the secondary orifices 6312 is provided to ensure the coding of the mounting of the cleaning head 64 with the base 62.

Figure 15 illustrates that a main channel 6321 extends from the main orifice 6311 towards the interior of the base 62 and is connected to the steam transmission orifice 670. This is thanks to the main channel 6321 that steam can be diffused from the steam transmission orifice 670 towards the main orifice 6311. Advantageously, as visible in Figure 16, the main channel 6321 has a section 63211 of frustoconical shape positioned at the level of the orifice main 6311, the section 63211 flaring towards the main orifice 6311. As described in more detail below, this flaring makes it possible to stabilize the fixing of the cleaning head 64 on the base 62.

In addition, two secondary channels 6322 extend, respectively, from the two secondary orifices 6312 towards the interior of the base 62. The main channel 6321 and the channels secondary channels 6312 extend in the same axial direction corresponding to the direction of coupling/uncoupling of the cleaning head 64 on the base 62. The secondary channels 6322 are used for keying during assembly of the cleaning head 64, but allow also to ensure mechanical consistency, as will be described in more detail below. In this regard, Figure 14 shows that an anti-rotation groove 63221 opens into at least one secondary channel 6322 and, as described in more detail below, is also useful for the mechanical consistency of the diffusion head of steam 61.

Figure 15 and Figure 16 show that the base 62 can comprise an intermediate coupling part 63, which can be removable relative to the base 62, and which comprises the coupling face 6310 and a plurality of walls delimiting the channel main channel 6321 and the secondary channels 6322. Figure 16 also illustrates that the main channel 6321 of the intermediate coupling piece 63 is extended by a hollow connection stud 63212 intended to be inserted within the end of the diffusion conduit of steam 74, at least one seal 63210 which can be arranged at the interface between the steam diffusion conduit 74 and the connection nipple 63212, preferably an O-ring surrounding the connection nipple 63212. The end of the nipple connector 63212 can be provided with projections intended to cooperate with the internal surface of the vapor diffusion conduit 74, once the connector stud 63212 inserted within the vapor diffusion conduit 74, so as to prevent tearing of the part intermediate coupling 63 of the base 62. Providing an intermediate coupling part 63 reduces the complexity of manufacturing the steam diffusion head 61, without increasing the complexity of mounting the steam diffusion member 6. This is however not limiting, since the main channel 6321 and the secondary channels 6322 can be integral with the base 62.

In Figure 15 and Figure 16 it can be seen more precisely that the intermediate coupling piece 63 advantageously comprises a plate 631 forming the coupling face 6310 and three protuberances 632 extending from the plate 631, each protuberance 632 comprising , respectively, a wall delimiting one of the main channel 6321 and the secondary channels 6322. Figure 15 even illustrates that the protuberances 632 forming the secondary channels 6322 can be provided to fix the intermediate coupling part 63 to the base 62. In this regard, attachment orifices 6322 can be provided at the end of each of the protuberances 632 forming the secondary channels 6322 which are opposite the plate 631, and be provided to be located opposite other orifices d The attachment 633 of the base 62 in order to accommodate attachment means (not shown), such as screws. Figure 1 illustrates that various cleaning heads 64 are intended to be removably coupled to the base 62, depending on the desired cleaning function and/or the surface to be cleaned. The cleaning head 64 shown furthest to the left in Figure 14 is intended for cleaning a window or a mirror, and is described in more detail below. The cleaning head 64 illustrated in the center of Figure 14 is intended for cleaning any type of flat surface, such as an induction hob or a work surface. The cleaning head 64 shown rightmost in Figure 14 is intended for cleaning grooves such as tile joints or faucet surrounds, and includes a brush in this regard. In any case, the cleaning head 64 comprises a connecting element 641 and at least two pins 642.

The connecting element 641 forms a channel for the diffusion of steam and extends projecting from the cleaning head 64. In addition, the connecting element 641 is intended to be inserted into the main channel 6321 to allow diffusion of steam from the main orifice 6311 through the cleaning head 64. In this regard, as also visible in Figure 14, it may be advantageous to provide the presence of at least one seal 640 arranged between the connecting element 641 and the main channel wall 6321, preferably an O-ring surrounding the connecting element 641. In addition, as visible in Figure 16, the connecting element 641 has a cross section at its axis of extension main channel 6321. In this way, the torque constraints likely to be exerted at the level of this cooperation, due to the use of the cleaning head 64, are better taken up, which improves the solidity of the cleaning head 64.

Each of the two pins 642 extends projecting from the cleaning head 64 on either side of the connecting element 641 and are intended to be inserted, respectively, in the two secondary channels 6322 to prevent a rotational movement of the cleaning head 64 relative to the base 62 once the cleaning head 64 is coupled to the base 62. In this way, the pins 642 make it possible to achieve mechanical cohesion of the cleaning head 64 on the base 62. Furthermore, once the assembly has been carried out, the pins 642 ensure the mechanical consistency of the steam diffusion member 6. Preferably, the pins 642 are provided to prevent rotation of the cleaning head 64 relative to L the base 62 around the main channel 6321, once the cleaning head 64 coupled to the base 62. In this regard, the pin intended to be inserted into the secondary channel 6322 provided with an anti-rotation groove 63221 is itself advantageously provided with an anti-rotation rib 6422 designed to cooperate with the anti-rotation groove 63221 so as to prevent this rotation of the cleaning head 64 relative to the base 62 around the main channel 6321, once the pin inserted into the secondary channel 6322. Furthermore, as illustrated in Figure 14, at least one of the pins 642, if this is the two pins 642, comprises at least one anchoring element 6421, for example longitudinal ribs extending radially from the pin 642, designed to cooperate with a wall delimiting the secondary channel 6322 in which the pin 642 is intended to be inserted, so as to prevent accidental removal of the cleaning head 64 from the base 62, by uncoupling the cleaning head 64 and the base 62, along the secondary channel 6322, preferably by friction against the wall of the secondary channel 6322. Preferably, each of the two pins 642 has an external shape which is not complementary to a shape of the secondary channel 6322 in which the pin 642 is intended to be inserted, so as to allow a forceful insertion of the pin 642 within the secondary channel 6322. In other words, the external transverse dimensions of the pin 642 are greater than the internal transverse dimensions of the secondary channel 6322, the notion of transverse here meaning an orthogonal plane in the main extension direction of the pins 642. The pins 642 are thus designed to be inserted by force inside the secondary channels 6322, which reinforces the mechanical coherence and solidity of the vapor diffusion member 6, despite the plurality of pieces that compose it.

The respective bases of the connecting element 641 and the pins 642 are preferably aligned along a transverse axis with cleaning head 64. However, each of the connecting element 641 and the pins 642 having a free end 6410 , 6420, opposite their base, the free end 6410 of the connecting element 641 advantageously extends beyond the free ends 6420 of the pins 642, relative to the cleaning head 64. This, combined with the relative positioning of the main orifice 6311 and the secondary orifices 6312, already described, ensures that, when mounting the cleaning head 64 on the base 62, it is the connecting element 641 which comes into contact with the main channel 6321 before the pins 642 come into contact with the secondary channels 6322. In this way, the mechanical cohesion of the cleaning head 64 on the base 62 is gradually achieved using the pins 642, which facilitates the assembly of the steam diffusion member 6.

From Figure 17 to Figure 20 is illustrated in more detail the steam diffusion member 6 of a steam diffusion accessory 4 equipped with a cleaning head 64 intended for cleaning surfaces, and more precisely windows.

As illustrated in particular in Figure 17, the cleaning head 64 intended for washing windows comprises a scraping element 643, a cleaning element 644 and a diffusion channel 645. The scraping element 643 is intended to extend at one end of the cleaning head 64 which is opposite the gripping handle 67 and allows a surface to be cleaned to be scraped. In addition, the scraping element 643 extends at one end of the steam diffusion member 6 which is opposite the end of the gripping handle 67 which is intended to be connected to the cord 7. As visible in Figure 17, the scraping element 643 comprises at least one rigid support blade 6431, preferably made of metal and advantageously made of aluminum, and a flexible blade 6432 advantageously comprising silicone. The support blade 6431 preferably surrounds at least a portion of the flexible blade 6432 according to the arrangement illustrated in Figure 17, in which it can be seen that a portion of the flexible blade 6432 which is opposite its end intended for scraping the surface can take the shape of a bulb 64320. The bulb 64320 is intended to fix the flexible blade 6432 to the support blade 6431, by being forcefully introduced into a fixing groove 64310 formed by an end portion of the blade support 6431 which is fixed on the cleaning head 64. This arrangement improves the efficiency of scraping by allowing the flexible blade 6432 to offer greater resistance to bending, due to its hold by the support blade 6431, while presenting a simple and practical construction. Figure 18 illustrates that the support blade 6431, the flexible blade 6432, the bulb 64320 and the fixing groove 64310 are designed to extend substantially transversely in relation to the gripping handle 67 and over the entire length of the cleaning head 64, in order to maximize the scraped surface.

The cleaning element 644, intended to come into contact with the surface to be cleaned, is capable of being humidified. In fact, the steam projected by the cleaning head 64 onto the surface to be cleaned condenses on contact with this surface, the scraping element 643 scraping the liquid thus formed, and the cleaning element 644 mopping up this liquid while rubbing the surface to clean it. Cleaning of the surface is thus improved. In this regard, the cleaning element 644 comprises a microfiber textile material, which is effective, inexpensive and lightweight.

As shown in Figure 17, the diffusion channel 645 is connected to the steam transmission orifice 670 and opens only between the scraping element 643 and the cleaning element 644. The diffusion channel 645 is in fact provided to diffuse steam from the transmission orifice to the surface to be cleaned, without projecting steam through the cleaning element 644. Thus, in operation, the cleaning element 644 is only humidified by the liquid condensed on the window and not by the vapor projected, which improves its absorption efficiency. From Figure 18 to Figure 20 it is illustrated that the cleaning head 64 advantageously comprises a transverse body 646 and a support 647, which facilitates the manufacture and assembly of the cleaning head 64.

The transverse body 646 extends from the gripping handle 67, and more precisely from the base 62, preferably transversely to a main extension direction of the gripping handle 67 in order to maximize the cleaned surface. The transverse body 646 can be in one piece with the gripping handle 67 or form a separate removable part relative to the gripping handle 67, typically via the base 62. Typically it is the transverse body 646 which comprises the the connecting element 641 and the pins 642 previously described. Furthermore, as illustrated in Figure 18, the transverse body 646 advantageously comprises a wall 6460 delimiting a first part of the diffusion channel 645 and surrounding the end of the connecting element 641 opening into the diffusion head of steam 61. This first part of the diffusion channel 645 extends in a rectilinear manner the connecting element 641 within the cleaning head 64. Figure 18 and Figure 19 also illustrate that the scraping element 643 is removable on the steam diffusion head 61, that is to say that the scraping element 643 is configured to be attached and fixed on the transverse body 646. Preferably a fixing member 6463, for example elastic hooks coming from molding with the transverse body 646, makes it possible to fix the scraping element 643, and more precisely the support blade 6431, to the steam diffusion head 61, in order to take up the forces to which the scraping element 643 is subjected in operation. If necessary, the support 647 can be configured to cooperate with the fixing member 6463 so as to participate in the fixing of the scraping element 643 to the steam diffusion head 61.

The support 647 is configured to be mounted on the transverse body 646 in a removable manner. In this regard, a locking component 6471 can be provided, the locking component 6471 being configured to fix the support 647 to the transverse body 646. As visible in Figure 19, the locking component 6471 preferably comprises an elastic tongue provided with 'a hook. The transverse body 646 may comprise a complementary component 6461, such as a latching groove, intended to be coupled to the locking component 6471 in order to keep the support 647 fixed relative to the transverse body 646, once these are coupled. 'to each other. Furthermore, the support 647 is provided to hold the cleaning element 644. More specifically, the cleaning element 644 is preferably removable and configured to be attached and fixed on the support 647, advantageously by means of an elastic component (not shown) arranged around the periphery of the cleaning element 644. In this regard, as particularly visible in Figure 16 and in Figure 17, the cleaning element 644 is designed to be fixed on the support 647 so as to isolate the diffusion channel 645 from the outside of the cleaning head 64. More precisely, the cleaning element 644 and the support 647 are designed so that the diffusion opening 649, described more in details below, i.e. the only steam escape route, all the other interstices of the cleaning head 64, and in particular the interfaces between the cleaning element 644 and the support 647, being steam-tight. In this way, liquid resulting from the condensation of the steam inside the cleaning head 64 cannot be projected outside the cleaning head 64, in particular when handling the steam diffusion member 6. Furthermore, as illustrated in Figure 20, the support 647 advantageously comprises a wall 6470 delimiting a second part of the diffusion channel 645, the wall 6460 being intended to abut the wall 6470 once the support 647 coupled to the transverse body 646. This wall 6470 is advantageously arranged so that steam circulating within the diffusion channel 645 is diffused over substantially an entire length of the cleaning head 64 in a direction of main extension of the cleaning head 64, i.e. that is to say a direction transverse to the gripping handle 67 once the cleaning head 64 assembled with the gripping handle 67, preferably between 60% and 90% of this length, for example 80% of this length. Thus, once the support 647 mounted on the transverse body 646, the transverse body 646 and the support 647 delimit a diffusion chamber 648 and a diffusion opening 649, which define an end part of the diffusion channel 645, the opening of diffusion 649 authorizing communication between the diffusion chamber 648 and the exterior of the cleaning head 64 so as to diffuse steam from the transmission orifice towards the diffusion opening 649.

Cord

From Figure 1 to Figure 7 it is illustrated that the cord 7 takes the form of a tube, preferably flexible. The cord section 7, in a plane transverse to the main extension direction of the cord 7 at rest, can be of any suitable shape, such as a circle or an oval, the shape of the cord 7 being adapted to the elements that the cord 7 has. cord 7 is provided to accommodate.

The cord 7 may comprise any suitable material, preferably liquid and gas tight, such as plastic. This is, however, not limiting since the cord 7 can also comprise a textile material, preferably woven, braided and/or knitted.

As visible in Figure 1, the cord 7 comprises a first end 71 intended to be connected to the vapor diffusion member 6 and a second end 72 intended to be connected to the connection member 8. In this regard, it can be provided to provide the steam diffusion accessory 3, 4, 5 with a fastening element 78 which is provided for prevent the cord 7 from being torn from the steam diffusion member 6. This attachment element 78 is also adapted to not limit the movements of the cord 7 relative to the steam diffusion member 6, in order to facilitate the manipulation of the steam diffusion accessory 3, 4, 5 by a user. As visible from Figure 1 to Figure 7, and in Figure 12, this attachment element 78 can take the form of a flexible sleeve surrounding the first end 71 of the cord 7, one end of the flexible sleeve being inserted into the the steam diffusion member 6, by means of a ball joint, the other remaining free, the wall of the flexible sleeve being provided with a plurality of through openings to increase the flexibility of the flexible sleeve.

Furthermore, the cord 7 is hollow and designed to accommodate at least one electrical sheath 73 and at least one steam diffusion conduit 74.

The electrical sheath 73, preferably flexible, is intended to surround and maintain at least one electrical wire 730 extending within the cord 7, so as to insulate it from the rest of the cord 7, in particular to insulate it electrically and from liquid and gas tight manner. In this regard, the electrical sheath 73 may comprise plastic. The electrical conduit

73 is preferably flexible, with a flexibility substantially identical to that of the cord 7, in order to accommodate the movements of the cord 7 when handling the steam diffusion accessory 3, 4, 5. The electrical sheath 73 allows also to hold together, if necessary, a plurality of electrical wires 730 within the cord 7. The electrical wires 730 are intended to circulate an electric current between the vapor diffusion base 2 and the vapor diffusion member 6 The electrical wires 730 can also be surrounded by an insulating sheath, in particular electrically insulating. The electric current circulating through the electric wires 730 can be associated with a control signal, typically coming from the trigger 671 to control the opening of the solenoid valve, or with an electrical power, typically from the steam diffusion base 2 to the electrically conductive element 661 to electrically power the heating sole 65.

The steam diffusion conduit 74 is intended to circulate steam produced within the steam diffusion base 2 to the steam diffusion member 6, via the connection member 8. In this regard, the steam diffusion conduit

74 has a first end 741 intended to be connected to the steam diffusion member 6. The steam diffusion conduit 74 can take the form of a flexible tube, with flexibility substantially identical to that of the cord 7 to accommodate the movements of the cord 7 during the handling of the steam diffusion accessory 3, 4, 5, and comprising a material impervious to liquids and gases, and in particular impervious to vapor, typically plastic. As visible from Figure 21 to Figure 27, a tip 75 is provided to be coupled to a second end 742 of the vapor diffusion conduit 74 which is opposite the first end 741 in order to connect the vapor diffusion conduit 74 to the steam diffusion base 2 in a removable manner. In this way the steam diffusion conduit 74 makes it possible to diffuse steam from the steam generator 21 towards the steam diffusion member 6. More precisely, as visible in Figure 12, the nozzle 75 is designed to extend within the connection channel 2022 when the cord 7 is connected to the vapor diffusion base 2 via the connection member 8. Furthermore, in this configuration of insertion of the tip 75 into the within the vapor diffusion base 2, through the connection opening 2021, the end piece 75 is intended to be coupled to the connection elements 2023 arranged on the side of the connection channel 2022 opposite the connection opening 2021, in order to be able to receive steam produced by the steam generator 21, via the supply conduit 214. In this regard, as visible in particular in Figure 10, at least one seal 753, preferably toric , can be arranged around the end piece 75, preferably being housed in a groove 750 formed at an external surface of the end piece 75, the seal 753 being designed to cooperate with one of the connection elements 2023 in the configuration of insertion of the tip 75 within the steam diffusion base 2, to prevent a steam leak within the connection channel 2022.

The end piece 75 extends substantially along a longitudinal axis X3-X3, typically taking a cylindrical external shape, for example cylindrical of revolution centered on the longitudinal axis X3-X3. In addition, the tip 75 is hollow to allow steam to circulate from the steam diffusion base 2 to the steam diffusion conduit 74. More precisely, the tip 75 comprises a wall delimiting a passage channel 763 of steam, which extends along a longitudinal axis X5-X5 crossing the nozzle 75 from side to side. Figure 27 thus illustrates that the passage channel 763 extends from a first end 751 of the tip 75 intended to be connected to the vapor diffusion base 2 to a second end 752 of the tip 75 intended to be connected to the cord 7. The passage channel 763 has over its entire length, with the exception of a restriction element 76 described in more detail below, a circular cross section whose diameter is preferably greater than 4.2 millimeters and advantageously between 4.2 and 5.2 millimeters.

According to Figure 26 and Figure 27, the tip 75 comprises a restriction element 76, preferably mechanical, configured to reduce a flow rate and/or modify a speed of steam flow coming from the diffusion base of steam 2. A mechanical restriction element 76 has the advantage of being simple and inexpensive to manufacture. This is however not limiting since the restriction element 76 could all either be electric or electronic, for example in the form of an electrically controlled variable aperture diaphragm. The restriction element 76 makes it possible to adapt the flow rate and/or the speed of flow of steam produced by the steam generator 21 as a function of the steam diffusion member 6 which is connected to the steam diffusion base 2. More specifically, the restriction element 76 is configured to reduce the steam flow from a flow rate of between 150 and 200 g/min to a flow rate of between 30 and 55 g/min. In this regard, it is advantageously the cleaning accessory 4 whose tip 75 comprises a restriction element 76. In fact, in this way, it is not necessarily necessary to modify the flow rate of steam diffused from the generator of steam 21 until connection opening 2021 when the processor detects a change of steam diffusion accessory 3, 4, 5, which simplifies the assembly, manufacture and operation of the steam diffusion base 2 In addition, provide that the restriction element 76 is arranged at the level of the end piece 75, that is to say at the level of the second end 742 of the steam diffusion conduit 74 rather than at the level of the. first end 741 of the steam diffusion conduit 74, or within the steam diffusion member 6, makes it possible to limit excess pressures within the steam diffusion conduit 74. In any case, this restriction element 76 also improves user safety.

Advantageously, as notably visible in Figure 26 and in Figure 27, the restriction element 76 extends within the passage channel 763, and has an external shape complementary to the passage channel 763. More precisely, the element restriction 76 may have a first portion 761 of frustoconical shape extending flaring towards the first end 751 of the tip 75 and a second portion 762 of straight shape extending towards the second end 752 of the tip 75 This form is simple and inexpensive to manufacture, while allowing effective flow reduction. The restriction element 76 is advantageously one-piece with the end piece 75, the wall of the passage channel 763 then forming the external shape of the restriction element 76, which facilitates the manufacture of the end piece 75 and limits the risks of evacuation of the restriction element 76 out of the nozzle 75, under the steam diffusion pressure. This is however not limiting, since the restriction element 76 could just as easily be attached within the passage channel 763, typically taking the form of a ring with an external shape complementary to that of the passage channel 763, and be designed to be attached and fixed there, typically by gluing.

To ensure the reduction of the flow through the restriction element 76, a steam passage orifice 760 is advantageously provided through the restriction element 76, preferably passing right through the restriction element 76, from one side to the other. so as to be in communication with the passage channel 763. This passage orifice 760 extends along a longitudinal axis X4-X4, which is preferably parallel to the Longitudinal axis at the level of the second right portion 762. Furthermore, the passage orifice 760 has a cross section at the longitudinal axis X4-X4 of the passage orifice 760 which is less than the cross section of the passage channel 763. More precisely, the cross section passage orifice 760 has the shape of a disc whose diameter is between 1.2 and 1.7 millimeters.

Figure 27 further illustrates that the restriction element 76 is preferably positioned equidistant from the first end 751 of the tip 75 and the second end 752 of the tip 75, which facilitates the manufacture of the end piece 75 by molding while limiting the risk that the mold, which in fact includes a weakness at the level of the restriction element 76, does not bend. Furthermore, once the connection member 8 is connected to the vapor diffusion base 2, the restriction element 76 is provided to be preferably positioned inside the vapor diffusion base 2, typically within of the connection channel 2022, ensuring vapor containment in the event of rupture of the restriction element 76.

From Figure 21 to Figure 23, but also in Figure 26, it is illustrated that a reinforcing member 77 can be provided to be arranged around the second end 72 of the cord 7. The presence of a reinforcing member 77 is, of course, not always obligatory, and generally depends on the type of steam diffusion accessory 3, 4, 5. The reinforcing member 77 is particularly useful for preventing the connection member 8 from being torn off. of the second end 72. As particularly visible in Figure 21 and Figure 26, the reinforcing member 77 extends along a longitudinal axis X6-X6 and has at least one first anti-tearing extension 7710 extending radially projecting towards the outside of the reinforcing member 77, the first anti-tearing extension 7710 being preferably metallic for structural reasons of resistance to tearing, the first anti-tearing extension 7710 being intended to cooperate with a second anti-tearing extension 81102 complementary to the connection member 8, as described in more detail below. Furthermore, as visible in Figure 21, the reinforcing member 77 comprises at least one turn, preferably a plurality of turns connected together in a spiral 771 extending along the longitudinal axis X6-X6 of the reinforcing member 77. In this case, at least a portion of the turn forms the first anti-tearing extension 7710. The spiral 771 offers the advantage of providing, in a single piece, a plurality of turns 7710, c that is to say first anti-tearing extensions, distributed along the axis of extension of the spiral 771. The reinforcing member 77 is preferably in the form of a tube intended to be fitted, typically in force, around the second end 72. The case where appropriate, the reinforcing member 77 comprises a sheath 772, preferably made of plastic material, which surrounds and maintains the entire turn 7710.

Connection body

The connection member 8 is illustrated in more detail from Figure 21 to Figure 26. The connection member 8 makes it possible to connect the steam diffusion accessory 3, 4, 5 to the steam diffusion base 2 of removable manner so as to allow diffusion of steam from the steam generator 21 towards the steam diffusion member 6 through the cord 7, preferably by insertion of the connection member 8 through the connection opening 2021 of the steam diffusion base 2.

In this regard, the connection member 8 may comprise a second locking element 8220 provided to cooperate with the first locking element 261 of the vapor diffusion base 2, already described with reference to Figure 9. As illustrated in FIG. Figure 11, the second locking element 8220 can typically take the form of a groove formed at an external surface of the connection member 8 intended to extend facing the first locking element 261 once the connection member 8 inserted in the connection opening 2021.

The connection member 8 comprises a coupling element 81 and, preferably, a connecting element 821, 822.

The coupling element 81 is intended to connect the connection member 8 to the cord 7, preferably by tightening the second end 72 of the cord 7.

In a variant (not shown) the coupling element 81 is also provided to connect the connection member 8 to the vapor diffusion base 2, typically by insertion through the connection opening 2021. If necessary, it is the coupling element 81 which comprises the second locking element 8220.

Generally speaking, the coupling element 81 has an elongated shape and extends along a longitudinal axis X7-X7, X8-X8. Furthermore, as notably visible in Figure 22 and in Figure 25, the coupling element 81 advantageously comprises a clamping part 811 and a sleeve 812.

The clamping part 811 comprises at least two complementary portions 8110, forming jaws, intended to grip at least one portion of the cord 7 at the second end 72. The complementary portions 8110 are elongated and extend along a longitudinal axis X7- X7. In this regard, at least one of the complementary portions 8110 advantageously comprises at least one protrusion 81101, such as a pin 81101 or a rib tightening 81101 visible in Figure 24, to reinforce the tightening of the cord 7, The protrusion 81101 extending from its active surface intended to come opposite the cord 7. Preferably, as also visible in Figure 21 and in Figure 24, the clamping part 811 further comprises at least one articulation element 8111, at least two of the complementary portions 8110 being connected by the articulation element 8111. In this way, the clamping part 811 is easier to handle. The articulation element 8111 and the at least two of the complementary portions 8110 are advantageously in one piece, which is easier to manufacture. Figure 21 illustrates that, in one embodiment, the clamping part 811 comprises three complementary portions 8110, while Figure 24 illustrates that, in an alternative embodiment, the clamping part 811 comprises two complementary portions 8110.

Figure 21 further illustrates that the clamping part 811 can be provided to grip the reinforcing member 77. To do this, the active surface of at least one of the complementary portions 8110, which is intended to extend in view of the reinforcing member 77, comprises at least a second anti-tearing extension 81102 extending projecting from the active surface. The second anti-tearing extension 81102 of the clamping part 811 is intended to cooperate with the first anti-tearing extension 7710 of the reinforcing member 77, already described, when the complementary portions 8110 enclose the securing member. reinforcement 77. This makes it possible to prevent a translation of the coupling element 81 relative to the reinforcement member 77 along the longitudinal axis X6-X6 of the reinforcement member 77, once the clamping part 811 attached to the reinforcing member 77. The second anti-tearing extension can advantageously take the form of a blocking rib 81102, which can extend along or transversely to the longitudinal axis X7-X7 of the complementary portions 8110. Figure 21 illustrates that the clamping part 811 can comprise a plurality of locking ribs 81102 distributed along the complementary portions 8110, some of which are transverse locking ribs 81102 extending transversely to the longitudinal axis X7-X7 of the portions complementary 8110 and provided to prevent translation of the clamping part 811 relative to the reinforcing member 77, and others are longitudinal blocking ribs 81102 extending along this longitudinal axis X7-X7 and provided to prevent rotation of the clamping part 811 to the reinforcing member 77 which, given the presence of the spiral 771 on the reinforcing member 77, also prevents a translation of the clamping part 811 relative to the reinforcing member 77. The blocking ribs 81102 advantageously have dimensions adapted to the dimensions of the spiral 771, in order to effectively prevent the connection member 8 from being torn from the cord 7. Thus, the transverse blocking ribs 81102 have a radial height substantially identical to the radial depth of the spaces between two successive turns 7710 of the spiral 771, while the longitudinal blocking ribs 81102 have a longitudinal length greater than or equal to the longitudinal spacing between two successive turns 7710 of the spiral 771. In this way, once the complementary portions 8110 in the clamping position of the reinforcing member 77, the turns 7710 of the spiral 771 abut 2013 against the blocking ribs 81102.

Figure 21 also illustrates that the clamping part 811 can further comprise a holding portion 8112 extending from at least one of the complementary portions 8110 along the Longitudinal axis X7-X7 of this complementary portion 8110. The portion holding device 8112 is intended to maintain the electrical sheath 73, and more precisely the end of the electrical sheath 73 intended to extend opposite the vapor diffusion base 2 when the connection member 8 is coupled to the base vapor diffusion pipe 2. In addition, the holding portion 8112 is provided to leave the steam diffusion conduit 74 free, and more precisely the nozzle 75. In this way, the sealing of the connection member 8 is improved. Furthermore, in the event of tearing of the connection member 8 of the cord 7, the holding portion 8112 contributes to the preservation of the electrical sheath 73 and, therefore, of the electrical wires 730 which are housed there. As visible in Figure 21, the holding portion 8112 preferably comprises a wall delimiting a holding channel 81120 inside which a portion of the electrical sheath 73 is intended to extend. In addition, the holding channel 81120 advantageously comprises an elbow 81121 designed to keep the electrical sheath 73 fixed relative to the clamping part 811, particularly in the event of the connection member 8 being torn off from the cord 7.

Figure 25 illustrates that the clamping part 811 can further comprise a first fixing element 81103 provided to cooperate with a second fixing element 8121 of the sleeve 812, described in more detail below, to keep the sleeve 812 fixed to the clamping part 811. The first locking element 261 can take the form of a lug extending projecting from an external surface of the clamping part 811, that is to say the surface opposite the active surface complementary portions 8110 of the clamping part 811, to cooperate by snap-fastening with the second fixing element 8121. In this regard, the second fixing element 8121, as visible in Figure 25, can take the form of a flexible tongue extending from an external surface of the sleeve 812, that is to say a surface radially opposite the surface of the sleeve 812 intended to come into contact with the clamping part 811, the tongue being provided to cooperate with the lug of the clamping part 811 by snapping. As illustrated in Figure 22, Figure 23 and Figure 25, the sleeve 812 is designed to be fitted onto the clamping part 811 so as to surround the clamping part 811 by tightening it and to keep the complementary portions 8110 fixed on the portion of the cord 7. Therefore, the sleeve 812 has a substantially elongated shape along a longitudinal axis X8-X8.

As visible in Figure 22 and Figure 23, alternatively or in addition to the snap-fastening, the sleeve 812 can be provided to be force-fitted around the clamping part 811 so as to be kept fixed relative to the part clamp 811. In this case, the sleeve 812 and the clamping part 811 can then advantageously be devoid of the fixing elements 81103, 8121.

As visible from Figure 9 to Figure 11, the connecting element 821, 822 is intended to cooperate with the connection opening 2021 and to extend within the connection channel 2022 so as to couple the connection member. connection 8 to the steam diffusion base 2.

In this regard, the connecting element 821, 822 is intended to be assembled to the coupling element 81 so as to surround the sleeve 812 and to be removably connected to the vapor diffusion base 2. Thus, the The connecting element 821, 822 is a substantially elongated part extending along a longitudinal axis X9-X9, X10-X10.

Figure 22, Figure 23 and Figure 24 illustrate that the connecting element 821, 822 can be in several pieces and comprise a longitudinal body 821 and a cover 822. This is however not limiting, since the connecting element connection 821, 822 could quite easily be formed in one piece.

The longitudinal body 821 has a first end 8211 which is crossed by the cord 7 at the level of a passage opening 8210. In addition, the longitudinal body 821 is intended to be assembled to the coupling element 81 by fitting, preferably in force along the longitudinal axis X7-X7, at least in part, and preferably in full, the sleeve 812, and extend beyond the coupling element 81 in a direction opposite to the cord 7. More precisely, the longitudinal body 821 has an elongated shape and s 'extends along a longitudinal axis X9-X9. In this way, the coupling element 81 is held fixed on the cord 7, and is protected by the longitudinal body 821 from any external projection.

In addition, the longitudinal body 821 may comprise a sealing flange 8214 positioned at the first end 8211 of the longitudinal body 821. The sealing flange 8214 extends radially towards the longitudinal axis X9-X9 and is provided to cooperate with a sealing rim 8120 of the sleeve 812, once the longitudinal body 821 fitted around the coupling element 81 so as to form a seal between the coupling element 81 and the longitudinal body 821. From this manner, liquid and/or gas is not likely to penetrate into the connection member 8 through the interface between the longitudinal body 821 and the sleeve 812. As visible in Figure 26, the sealing rim 8120 is positioned at the end of the coupling element 81 closest to the vapor diffusion member 6 once the coupling element 81 is tightened around the second end 72.

Furthermore, as illustrated in Figure 26, the longitudinal body 821 comprises a second end 8212, opposite the first end 8211, comprising a sealing lip 8213 extending over the entire circumference of the longitudinal body 821, projecting from a radially outer rim of the longitudinal body 821. Of course, several sealing lips can be provided on the outer rim. The sealing lip 8213 is designed to cooperate with at least one complementary sealing groove 8222, provided at the level of the cover 822, as described in more detail below.

As visible from Figure 9 to Figure 11, the cover 822 is intended to connect the connection member 8 to the steam diffusion base 2, that is to say to be removably connected to the base of diffusion of vapor 2, typically by cooperation with the connection channel 2022 after introduction through the connection opening 2021. In this regard, the cover 822 is intended to be assembled to the longitudinal body 821 by fitting along the longitudinal axis X9 - -X10. Furthermore, where appropriate, it is the cover 822 which comprises the second locking element 8220 intended to cooperate with the first locking element 261 of the vapor diffusion base 2, in the manner illustrated in FIG.

Figure 26 illustrates that the cover 822 comprises an external wall 8221 having an end coming into contact with the sealing lip 8213 in which a sealing groove 8222 is provided. The sealing groove 8222, also visible in Figure 23 and Figure 25, extends over the entire periphery of the cover 822 and is designed to cooperate with the sealing lip 8213 once the cover 822 is fitted onto the longitudinal body 821 so as to form a seal between the cover 822 and the longitudinal body 821. In this way, liquid and/or gas does not risk penetrating within the connection member 8 through the interface between the longitudinal body 821 and cover 822. If necessary, a plurality of sealing grooves can be provided. Figure 25 and Figure 26 further illustrate that the cover 822 may include a separation wall 8223 delimiting a steam chamber 8224 and an electrical chamber 8225.

The steam chamber 8224 is designed to accommodate one end of the steam diffusion conduit 74, in particular the nozzle 75, which is designed to extend within the steam chamber 8224 when the connection member 8 is connected at the second end 72. Thus, the connection member 8, and more precisely the cover 822, is provided to hold the end piece 75 during the introduction of the connection member 8 within the connection opening 2021 of the vapor diffusion base 2. In this regard, Figure 26 illustrates that a holding orifice 82240 can be provided passing through a wall of the cover 822 intended to extend opposite the connection elements 2023 arranged in the bottom of the connection channel 2022. In addition, the end piece 75 is provided to extend through the holding orifice 82240 in order to, precisely, be able to cooperate with at least one of the connection elements 2023 to connect the steam diffusion conduit 74 to the supply conduit 214 of the steam diffusion base 2. Figure 10 illustrates that at least one seal 82241, for example O-ring, can surround the end piece 75 at the level of the portion of the tip 75 intended to extend opposite the holding orifice 82240. The seal 82241 has the advantage of allowing both a slight transverse movement of the tip 75 in the orifice holding device 82240, which allows automatic alignment of the end piece 75 in the connection element 2023 connected to the steam conduit 74, and to form an additional sealing barrier which makes it possible in particular to prevent steam from penetrating not inside the connection member 8 in the event that leaks appear at the seals 753 when the connection member 8 is connected to the vapor diffusion base 2.

In the same way, the electrical chamber 8225 is designed to accommodate at least one end of an electrical wire 730 extending projecting from one end of the electrical sheath 73, in the manner for example visible in Figure 24. The end of each electrical wire 730 is in fact intended to extend inside the electrical chamber 8225 when the connection member 8 is connected to the second end 72. In addition, the electrical chamber 8225 is intended to accommodate a terminal 82250 for holding the electrical wires 730, visible from Figure 21 to Figure 23, and in Figure 25 and Figure 26. From Figure 21 to Figure 23 is further illustrated that the electronic component 82251, whose resistance is measured by the sensor of the vapor diffusion base 2 to determine which type of vapor diffusion accessory 3, 4, 5 is connected to the vapor diffusion base 2, can typically be arranged at the terminal 82250. Furthermore, a sealing sleeve (not shown) can also be housed within the electrical chamber 8225, being positioned between the terminal 82250 and the end of the electrical sheath 73. The sealing sleeve can surround the electrical wires 730 and come to bear against the cover 822 so as to hold the electrical wires 730 between them, but also to prevent contact between the electrical wires 730 and steam which would have been introduced into the connection member 8. Furthermore, retaining orifices 82240 can be provided passing through the cover 822, and more precisely at through a wall of the cover 822 intended to extend opposite the connection elements 2023 arranged in the bottom of the connection channel 2022, the ends of the electrical wires 730 being intended to extend through the holding orifices 82240 in order to, precisely, to be able to cooperate with at least one of the connection elements 2023 to connect the electrical wires 730 to the electrical circuit of the vapor diffusion base 2.

To guarantee the mechanical consistency of the connection member 8, but also to improve its tightness, a fixing system is provided to align the longitudinal axis X7-X7, X8-X8 of the coupling element 81, the longitudinal axis X9-X9 of the longitudinal body 821 and the longitudinal axis the different components of the connection member 8 are made axially, which limits the risks of radial penetration of liquid and/or gas within the connection member 8. The fixing system is also designed to maintain fixed the coupling element 81, the longitudinal body 821 and the cover 822 relative to each other, once the coupling element 81, the longitudinal body 821 and the cover 822 assembled.

In this regard, the fixing system may include a support element 831, visible in Figure 22, in Figure 23 and in Figure 26. The support element 831 extends projecting from the cover 822 in a direction opposite to one end of the cover 822 intended to cooperate with the vapor diffusion base 2. Preferably, the support element 831 extends the separation wall 8223 of the cover 822. In addition, the support element 831 is intended to cooperate with the sleeve 812, so as to ensure axial support of the cover 822 on the coupling element 81 once the coupling element 81, the longitudinal body 821 and the cover 822 assembled. The support element 831 can thus comprise two tabs 831, which are intended to exert an axial force on the sleeve 812 and/or the clamping part 811, once the connection member 8 assembled, which axial force is transmitted to the longitudinal body 821 via the sealing rim 8120 of the sleeve 812 and the sealing flange 8214 of the longitudinal body 821, then returns to the cover 822 via the cooperation of sealing lip 8213 and the sealing groove 8222. This stress circuit improves the mechanical consistency and the tightness of the connection member 8. Figure 26 further illustrates that the fixing system can comprise a plurality of rods 832 extending projecting from the longitudinal body 821 in a direction opposite to the passage opening 8210. Each rod is preferably integral with the longitudinal body 821 and is designed to cooperate with one of the end piece 75 of the steam conduit, the lug 82250 for holding the electrical wires 730, so as to hold the end piece 75 and/or the lug 82250 in position relative to the longitudinal body 821. The structural coherence of the connection member 8 is thus reinforced.

Furthermore, as can be seen in Figure 23, the fixing system can further comprise a first screw support 8341, for example in the form of a hollow cylinder having a screw pitch, extending projecting from the body longitudinal 821, in the direction of the cover 822, so as to be positioned opposite a first orifice provided in the cover 822, the first screw support 8341 receiving a first fixing screw 835, visible in Figure 25, intended to fix the cover 822 on the longitudinal body 821. In the same way, a second screw support 8342 can extend projecting from the longitudinal body 821, in the direction of the cover 822, so as to be positioned opposite a second orifice provided in the cover 822, the second screw support 8342 receiving a second fixing screw 835 intended to fix the cover 822 on the longitudinal body 821. Figure 26 even illustrates that a third orifice 8333 can be provided through the cover 822 and put in communication the electrical chamber 8225 with the exterior of the cover 822. A third screw support 8343 can also be provided within the lug 82250 so as to be positioned opposite a third orifice 8333 provided in the cover 822, the third screw support 8343 receiving a third fixing screw 835, illustrated in Figure 25, intended to fix the lug 82250 to the cover 822.

Assembly of the connection member

From Figure 21 to Figure 25 is illustrated a method of assembling the different components of the connection member 8.

As visible from Figure 21 to Figure 23, When present, the reinforcing member 77 is first fitted at the second end 72 opposite the vapor diffusion member 6.

Whether the reinforcing member 77 is present or not, as visible in Figure 21 and in Figure 24, the steam diffusion conduit 74 and the electrical sheath 73 are arranged within the cord 7 so as to present one end extending beyond the second end 72. The electrical wires 730 are previously housed within the electrical sheath 73. The longitudinal body 821 is fitted onto the second end 72 of the cord 7, then shifted towards the first end 71 of the cord 7 while awaiting the continuation of the assembly. Then, the same is done for the sleeve 812, as visible in Figure 22 and Figure 25. In fact, these parts 821, 812 must be arranged first on the cord 7 because, once the end piece 75 and the terminal 82250 assembled, respectively, with the steam conduit and the electrical wires 730, it is no longer possible, given their size, to arrange the longitudinal body 821 and the sleeve 812 around the steam diffusion conduit 74 and the electrical sheath 73.

Once the longitudinal body 821 and the sleeve 812 arranged around the cord 7, the end piece 75 is fixed at the end of the vapor diffusion conduit 74 which extends beyond the second end 72, and each of the ends of the electrical wires 730 is fixed to the lug 82250.

The clamping part 811 is mounted on the second end 72 of the cord 7 and, where appropriate, on the reinforcing member 77. To do this, the complementary portions 8110 forming jaws are brought to the level of the second end 72 then manipulated so as to grip the second end 72. As visible in Figure 21, when the holding portion 8112 is present, the free end of the electrical sheath 73 is arranged within the holding portion 8112 so as to be held, and this before the complementary portions 8110 are manipulated to grip the second end 72.

As illustrated in Figure 23, the sleeve 812 is then slid along the cord 7 to fit around the clamping part 811, so as to keep it fixed, either by force fitting, or by snap-fastening of the fixing elements. lockdown.

Subsequently, as notably visible in Figure 25, the longitudinal body 821 and the cover 822 are manipulated to come facing and in contact with one another along their respective longitudinal axis X9-X9, X10-X10 , The rods 832 of the longitudinal body 821 cooperating with the lug 82250, the end piece 75 and the cover 822, the sealing lip 8213 cooperating with the sealing groove 8222 and the sealing flange 8214 cooperating with the rim of sealing 8120.

The fixing screws 835 are, finally, introduced through the cover 822 and all of the components of the connection member 8 are fixed to each other by tightening the fixing screws 835 in each of their screwing support 8341, 8342, 8343.

Once the steam diffusion base 2 is assembled on one side, and the different parts of the steam diffusion accessory 3, 4, 5 on the other, the household appliance 1 is ready to operate.

To do this, the steam diffusion base 2 is connected, via its electrical cable 271, to a source of electrical power, typically the domestic electrical sector. Reservoir 211 is filled with water by the user.

The steam diffusion base 2 is powered up, typically by actuation of the switch, and steam is produced within the tank 210.

Before, or not, powering up the vapor diffusion base 2, the connection member 8 is introduced through the connection opening 2021 until the user feels that the first locking element 261 and the second locking element 8220 have cooperated well to fix the connection member 8 within the connection channel 2022 and connect the end piece 75 and the electrical wires 730 to the connection elements 2023 arranged at the bottom of the connection channel 2022 In this way, the steam diffusion accessory 3, 4, 5 is connected to the electrical circuit and to the supply conduit 214 of the steam diffusion base 2.

If applicable, the type of steam diffusion accessory 3, 4, 5 is detected by the steam diffusion base 2 in order to adapt its operation accordingly.

To do this, once the steam diffusion accessory 3, 4, 5 is connected to the steam diffusion base 2 by means of the connection member 8, the measurement of a value of a electrical resistance of the electronic component 82251. This measurement is advantageously carried out by the sensor of the vapor diffusion base 2 which transmits the result of the measurement to the processor. From there, the operation of the vapor diffusion base 2 is controlled by the processor, based on a measurement result.

The control allows, primarily, to adapt the flow rate and/or the speed of steam flow to be diffused from the steam diffusion base 2 to the steam diffusion member 6. In this regard, the control advantageously includes modifying the flow rate of steam to be diffused from the steam diffusion base 2 towards the steam diffusion accessory 3, 4, 5 so as to place the flow rate within one of three different flow rate ranges. A first of the three flow ranges extends from 30 g/min to 55 g/min, a second of the three flow ranges extends from 120 g/min to 180 g/min and a third of the three flow ranges s extends from 120 g/min to 170 g/min. Thus, when the detected accessory is an iron 3, the control includes the regulation of the steam flow diffused from the base of steam diffusion 2 so as to place the flow rate in a range extending from 120 g/min to 180 g/min. In addition, when the accessory detected is a steaming accessory 5, the control includes the regulation of the steam flow rate diffused from the steam diffusion base 2 so as to place the flow rate in a range extending from 120 g/min at 170 g/min. When the detected accessory is the steam diffusion accessory 4 intended for cleaning, the control may include regulating the flow of steam diffused from the steam diffusion base 2 so as to place the flow in a range extending from 30 g/min to 55 g/min. However, and preferably, the regulation of the steam flow is not modified when the cleaning accessory 4 is detected, the restriction element 76 present in the connection member 8 ensuring, by itself, the modification of the flow rate of steam to be diffused from the steam diffusion base 2 towards the cleaning accessory 4 so as to place the flow rate in a range extending from 30 g/min to 55 g/min. In this way, the operation of the steam diffusion base 2 is simplified and the cleaning accessory 4 is available immediately after connection, without having to wait for the tank 210 to cool down.

To implement this modification of the steam flow rate to be diffused from the steam diffusion base 2 to the steam diffusion accessory 3, 4, 5, it may be necessary to modify the pressure and/or temperature parameters at within the steam generator 21, and more precisely within the tank 210. This modification of the steam flow and/or the pressure is carried out, in a manner known per se, by controlling the electrical supply of the electrical resistance of the tank 210. Moreover, in order to prevent excessive steam flow rates from being suddenly diffused towards the steam diffusion accessory 3, 4, 5, the control can include the modification of the temperature within the steam generator 21 according to a time sequence comprising temperature levels.

Alternatively, the control makes it possible to adapt the behavior of the steam diffusion accessory 3, 4, 5, and more precisely of the steam diffusion member 6.

In this regard, the control may include modifying the electrical current supply to the steam diffusion accessory 3, 4, 5. In fact, the electrical current circulating through the electrical wires 730 to power the resistive electrical wire 661 can be interrupted or not depending on the signal emitted by a temperature sensor carried by the sole 65 so as to regulate the temperature of the sole 65 around a set temperature.

Between two successive uses of the steam diffusion accessory 3, 4, 5, or before removing the connection member 8 from the steam diffusion base 2, the steam diffusion member 6 can be arranged within the storage space 2010. In this regard, the steam diffusion member 6 can be suspended from the retaining member 2011, as visible in Figure 5 for the steaming accessory 5 or in Figure 6 for the cleaning accessory 4. Likewise, the steam diffusion member 6 can cooperate with the stop 2013 and extend substantially vertically, as visible in Figure 2 for the iron 3. In this position, if liquid is projected onto the iron 3 and enters it, the evacuation systems 672 ensure that the liquid will not stagnate inside the iron 3 , and in particular not inside the gripping handle 67, so that the proper functioning of the iron 3 is preserved.

As visible in Figure 3 and in Figure 4, the steam diffusion member 6 can be more firmly held within the storage space 2010, in particular by cooperation, on the one hand, of the recess of hooking 676 of the steam diffusion member 6 and the stop 2013 of the steam diffusion base, and on the other hand, by deployment of the retaining member 2011.

Of course, once the connection member 8 has been decoupled from the steam diffusion base 2, the steam diffusion member 6 can be maintained within the storage space 2010, even if another steam diffusion accessory steam 3, 4, 5 is connected to the steam diffusion base 2, or if the household appliance 1 is transported. To prevent the cord 7 from hindering transport, it can be folded and stored on the steam diffusion base 2 using the tab 251.

To decouple the connection member 8 from the vapor diffusion base 2, by removing the connection opening 2021, the first locking element 261 is manipulated so that the user perceives that the connection member 8 is no longer firmly held within the connection channel 2022, and can remove the connection member 8 from the vapor diffusion base 2. The shutter panel 241 is then deployed to close the connection opening 2021 and preserve the sealing of the steam diffusion base 2. Therefore, another steam diffusion accessory 3, 4, 5 can be connected to the steam diffusion base 2, via its connection member 8, this other steam diffusion accessory 3, 4, 5 can be detected and the steam diffusion base 2 have its operation adapted by the processor accordingly.

The steam diffusion accessory 3, 4, 5 is activated by pressing the trigger 671, so as to project the steam onto the item to be treated (laundry or surface to be cleaned). In the case of a surface, such as a window, the steam is projected evenly along the entire cleaning head 64, condenses, is scraped by the scraping element 643 then mopped up by the cleaning element. cleaning 644.
