Description

Technical Field

[0001] The present disclosure relates to the field of household appliances. More specifically, the present disclosure relates to a steam diffusion household appliance. Background Art

[0002] Some household appliances use steam to clean surfaces, such as window panes. Once sprayed onto the surface, the steam condenses and it is necessary to be able to drain the liquid resulting from this condensation. In this regard, appliances of this type propose the use of a small scraper and / or a wiper integrated into the steam diffusion nozzle. However, none of these appliances is completely satisfactory, in particular because the relative positioning of the small scraper, the wiper and the steam spray zone does not allow for effective drainage of the liquid resulting from the condensation, nor does it optimize the diffusion of the steam on the surface. Typically, in some appliances, the steam is partially sprayed onto the wiper, which becomes wet, which reduces its ability to absorb the liquid resulting from the condensation. Summary of the invention

[0003] One object of the present disclosure is to improve the efficiency of household appliances in cleaning surfaces by steam diffusion.

[0004] Another object of the present disclosure is to improve the operation of household appliances for cleaning surfaces by steam diffusion.

[0005] Another object of the present disclosure is to propose a household appliance for cleaning surfaces by steam diffusion, which has an economical and reliable structure and which is quick to use.

[0006] To this end, according to one aspect of the present disclosure, a cleaning attachment for diffusion by steam is provided, the cleaning attachment comprising:

[0007] a steam diffusion handle, a steam transmission hole being disposed at one end of the handle; and

[0008] A cleaning head extending from the handle to an end portion provided with the steam transmission hole, the cleaning head comprising:

[0009] an element for scraping the surface to be cleaned;

[0010] a cleaning element adapted to be wetted and brought into contact with the surface to be cleaned; and

[0011] A diffusion channel, which is connected to the transmission hole and opens only between the scraping element and the cleaning element, is designed to diffuse steam from the transmission hole.

[0012] Due to the configuration of the diffusion channel, when the cleaning attachment is used, steam is not sprayed onto the cleaning element. Therefore, its efficiency is improved when scraping, since it is not wetted during the steam spraying process. In addition, considering the relative positioning of the scraping element, the cleaning element and the diffusion channel, the sprayed steam condensed on the surface to be cleaned is immediately scraped by the scraping element, and then the scraped liquid is immediately wiped by the cleaning element, which improves the efficiency and operation of the cleaning attachment.

[0013] Cleaning heads may include:

[0014] a transverse body extending from the handle; and

[0015] A support for holding a cleaning element and configured to be removably mounted on the lateral body.

[0016] Once the support is mounted on the transverse body, the transverse body and the support may define a diffusion chamber and a diffusion opening which define a terminal portion of the diffusion channel, the diffusion opening allowing communication between the diffusion chamber and the outside of the cleaning head so as to diffuse steam from the transmission hole to the diffusion opening.

[0017] The lateral body may include a first wall defining a first portion of the diffuser channel.

[0018] The support may include a second wall defining a second portion of the diffuser passage.

[0019] The second wall may be arranged such that steam circulating in the diffusion channel is diffused substantially over the entire length of the cleaning head in a main extension direction of the cleaning head.

[0020] The transverse body may extend transversely to a main extension direction of the handle.

[0021] The scraping element may be configured to be attached and fixed to the transverse body, preferably by means of a metal fixing member.

[0022] The cleaning attachment may further comprise a locking member configured to secure the support to the transverse body, the locking member preferably comprising a resilient tongue provided with a hook.

[0023] The cleaning element may be removable and configured to be attached and fixed to the support, preferably by means of elastic members.

[0024] The scraping element may comprise a support blade, preferably made of metal, and a flexible blade, preferably made of silicone.

[0025] The cleaning elements may comprise a microfiber fabric material.

[0026] According to another aspect of the present disclosure, a household appliance is provided, comprising:

[0027] Cleaning accessories as described above; and

[0028] A steam diffusion base includes a steam generator and is designed to be connected to a cleaning accessory so as to diffuse steam from the steam generator toward the transmission hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Home appliances

[0059] Figure 1 A household appliance 1 is shown, ie an appliance which operates with electricity and is used to meet household needs.

[0060] The household appliance 1 can perform various functions, such as treating laundry, typically ironing and / or pressing clothes, and / or cleaning surfaces such as window panes. To achieve these functions, the household appliance 1 is configured to diffuse steam, preferably water vapor.

[0061] The household appliance 1 is portable in that it is designed to be easily carried by a user.

[0062] The household appliance 1 comprises a steam diffusion base 2 and steam diffusion accessories 3 , 4 , 5 which are removable relative to the steam diffusion base 2 .

[0063] Vapor diffusion base

[0064] like Figures 1 to 7 As shown, the vapour diffusion base generally takes the form of a substantially frustoconical box, although this is of course not limiting, as any form of vapour diffusion base 2 may be envisaged, such as a parallelepiped.

[0065] The vapor diffusion base 2 comprises a support surface 200 and a plurality of side surfaces 201 , 202 extending from the support surface 200 , the support surface 200 being arranged to place the vapor diffusion base 2 on a substantially horizontal and flat surface, typically on the ground.

[0066] In the present disclosure, the terms "horizontal" and "vertical" are used to refer to the use of the household appliance 1, wherein the support surface 200 is flat on a plane, and an element is horizontal when the element extends substantially parallel to the plane, and is vertical when the element extends substantially perpendicular to the plane. Similarly, the terms "lower" (or "bottom") and "upper" (or "top") refer to areas of the household appliance that are closer to or farther from the plane where the support surface 200 is located, respectively.

[0067] Furthermore, the steam diffusion base 2 is advantageously portable, and for this purpose may include a transport handle 22 located at the upper end of the steam diffusion base (i.e., the end opposite to the support surface 200), the transport handle 22 being used to transport the steam diffusion base 2. The transport handle 22 may take any suitable shape and size, and may even be provided with a hook component 220, for example having a surface with a higher roughness than the rest of the transport handle 22, which extends from the transport handle 22 to facilitate gripping by the user, typically by preventing the user's hand from sliding on the transport handle 22.

[0068] At least one of the side faces 201, 202 of the steam diffusion base 2 extends substantially vertically to the support surface 200 and defines a storage space 2010, which is designed to receive the steam diffusion member 6 of the steam diffusion accessories 3, 4, 5, which steam diffusion member 6 is described in more detail below. Substantially vertical means that the angle between the side face 201 and the support surface 200 is between 80° and 100°. Therefore, the steam diffusion base 2 provides a storage space 2010, in which the steam diffusion member 6 extends in a substantially vertical position, which facilitates the transportation of the household appliance 1, in particular because the gripping of the transport handle 22 of the steam diffusion base 2 is not hindered by the presence of the steam diffusion member 6. The side face 201 provided with the storage space 2010 can be formed in a plate 2012, which advantageously includes a material that can withstand temperatures above 250°C. The plate 2012 is attached and fixed to the steam diffusion base 2. As Figures 2 to 7 As shown, the storage space 2010 is designed to receive the steam diffusion member 6, whether it is connected to the steam diffusion base 2 or not. The storage of the steam diffusion member 6 of the steam diffusion attachment 3, 4, 5 on the steam diffusion base 2 can be used, for example, between two consecutive uses of the steam diffusion attachment 3, 4, 5, or for transporting the household appliance 1.

[0069] In order to ensure the storage of the steam diffusion member 6 on the steam diffusion base 2, in particular during the transportation of the household appliance 1, the holding member 2011 is positioned at the side 201 of the steam diffusion base 2, which is provided with a storage space 2010, preferably at the upper end of the side 201, i.e. at the end opposite to the support surface 200, so as to avoid that the actuation of the holding member 2011 is hindered by the presence of the ground when the steam diffusion base 2 is placed on the ground and the steam diffusion member 6 is arranged in the storage space 2010. The holding member 2011 can actually be relatively close to the steam diffusion base 2. Figure 1 and Figure 2 The retracted position and Figures 3 to 7The retaining member 2011 can be moved between the deployed positions shown, in which in the retracted position the retaining member 2011 allows the steam diffusion member 6 to be withdrawn from the storage space 2010, and in the deployed position the retaining member 2011 keeps the steam diffusion member 6 fixed in the storage space 2010. This allows a simple and practical operation of the household appliance 1, which facilitates its transport and storage. The retaining member 2011 is preferably rotatably movable relative to the steam diffusion base 2 and advantageously takes an arched shape. This is in fact the mobility and structural form of the retaining member 2011, which is easy to use and inexpensive to manufacture. In its deployed position, the retaining member 2011 can cooperate with different parts of the steam diffusion attachments 3, 4, 5, such as Figures 3 to 7 As shown, in particular, it cooperates with the attachment element 674 of the vapor diffusion attachment described in more detail below.

[0070] Figure 7 It is also shown that the holding member 2011 may include a suspension element 20111 extending from the holding member 2011, preferably protruding, and designed to hold the vapor diffusion member 6 fixed in place when the holding member 2011 is in the deployed position. Figure 5 and Figure 6 The suspension element 20111 can advantageously take the form of a hook extending from the retaining member 2011, preferably 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 vapor diffusion member 6 is temporarily arranged in the storage space 2010 (usually between two consecutive uses of the vapor diffusion attachment 3, 4, 5). In this respect, Figure 5 The steam diffusion member 6 of the ironing attachment 5 is shown in a hanging position, while Figure 6 The steam diffusion member 6 of the cleaning attachment 4 is shown in a hanging position. This facilitates the operation of the household appliance 1.

[0071] In order to stabilize the vapor diffusion member 6 of the vapor diffusion attachment 4, 5 when the vapor diffusion attachment 4, 5 is in the hanging position, as shown in FIG. Figure 7 As shown, the holding member 2011 may include a fixing element 20112 configured to prevent the vapor diffusion member 6 from tipping laterally relative to the vertical direction when the vapor diffusion member 6 is in the hanging position. The fixing element 20112 may take the form of a rib extending protruding from the holding member 2011, for example, protruding from a surface of the holding member 2011 that faces the vapor diffusion base 2 when the holding member 2011 is in the retracted position. In the deployed position of the holding member 2011, the fixing element 20112 may cooperate with different parts of the vapor diffusion member 6 of the vapor diffusion attachment 3, 4, 5, such as Figures 2 to 7 As shown, in particular, it cooperates with the guide element 675 of the vapor diffusion member 6 described in more detail below.

[0072] Figure 2 , Figure 3 and Figure 4 The vapor diffusion base 2 is shown to further include a stopper 2013 extending from the side 201 provided with the storage space 2010. The stopper 2013 is designed to cooperate with the complementary hook recess 676 of the vapor diffusion attachment 3, 4, 5 when the vapor diffusion member 6 is arranged in the storage space 2010, as described in more detail below. Figure 2 As can be seen more precisely in FIG. 2 , the stopper 2013 can be used in particular for temporarily arranging the steam diffusion member 6 in the storage space 2010, typically for placing the steam diffusion member 6 of the ironing attachment 3 on the steam diffusion base 2 between two consecutive uses. In addition, the stopper 2013 can be used in particular for improving the retention of the steam diffusion member 6 in the storage space 2010, such as Figure 4 2010 and includes a gripping handle 67, a portion of which cooperates with a retaining member 2011, and wherein a hook recess 676 provided in a steam diffusion head 61 of the steam diffusion member 6 of the ironing attachment 5 cooperates with a stopper 2013. Advantageously, the stopper 2013 takes the form of an appendage extending protruding from a side 201 provided with the storage space 2010, as Figure 4 In addition, the stopper 2013 is positioned closer to the support surface 200 than the retaining member 2011. In other words, the retaining member 2011 extends a first distance from the support surface 200, and the stopper 2013 extends a second distance from the support surface 200, which is less than the first distance. In this way, the vapor diffusion member 6 has two hook points to be retained in the storage space 2010, which ensures the transportation of the household appliance 1.

[0073] Figure 1 It is also shown that the vapor diffusion base 2 can include a retaining member 251 extending from the vapor diffusion base 2, which retaining member advantageously takes the form of a flexible tongue provided with a through hole designed to cooperate with a retaining tab 252 extending protruding from the vapor diffusion base 2. The retaining member 251 is designed to hook the cable 7 of the vapor diffusion attachment 3, 4, 5, which is described in more detail below, in particular when the vapor diffusion member 6 is arranged in the storage space 2010.

[0074] The vapor diffusion base 2 also includes a housing 20 forming a jacket, which allows the various components of the vapor diffusion base 2 to be sealed against splashes of liquid. The housing 20 may include any suitable material, such as plastic or metal. If necessary, a plate 2012 in which the storage space 2010 is arranged is attached and fixed to the housing 20. Alternatively, the housing 20 may include a side 201, and the storage space 2010 is arranged in the side 201. Similarly, the support surface 200 may be formed by one side of the housing 20, or as Figure 1 As shown, it is at least partially formed by the outer surface of the pad 2000 protruding from the shell 20, and the pad 2000 is attached and fixed to the shell 20, or is integral with the shell 20. In addition, the delivery handle 22 of the vapor diffusion base 2 can protrude and extend from the upper end of the shell 20, that is, opposite to the support surface 200, and is integral with the shell 20 or attached and fixed to the shell 20.

[0075] The steam diffusion base 2 is used to supply steam to the steam diffusion accessories 3 , 4 , 5 .

[0076] For this reason, Figure 8 As shown, the steam diffusion base 2 includes a steam generator 21 arranged in the housing 20. The steam generator 21 can have various structures and generally includes a tank 210 for generating steam under pressure, and the tank 210 is supplied with liquid, preferably water, through a reservoir 211, and the reservoir 211 is generally removable relative to the steam diffusion base 2. The tank 210 can include steel, typically stainless steel, and can be equipped with an electric heating resistor for generating steam under pressure. The liquid can be transferred to the tank 210 from the reservoir 211 by a supply circuit 212 including a pump 213 (typically a high-pressure electromagnetic pump 213).

[0077] like Fig. 9 , Fig.10 and Fig.11 As shown, the side 202 of the vapor diffusion base 2 is defined by a surface of the housing 20, which includes a surface 202 penetrated to provide a connection opening 2021. The connection opening 2021 is designed to cooperate with the connection member 8 of the vapor diffusion attachment 3, 4, 5 in a detachable manner, such as Figure 3 , Fig.10 and Fig.11 It is particularly visible in that the connecting member 8 is introduced into the connecting opening 2021 to connect the steam diffusion attachments 3, 4, 5 to the steam diffusion base 2, for diffusing steam from the steam generator 21 to the steam diffusion attachments 3, 4, 5, or is removed from the connecting opening 2021, for disconnecting the steam diffusion attachments 3, 4, 5 from the steam diffusion base 2.

[0078] To this end, the supply pipe 214 is advantageously connected to the steam generator 21 and is arranged to diffuse steam from the steam generator 21 to the connection opening 2021. In this regard, the steam diffusion base 2 may include a solenoid valve 215 arranged at one end of the tank 210, the operation of which controls the diffusion of steam from the tank 210 to the supply pipe 214.

[0079] In addition, if Fig. 9 , Fig.10 and Fig.11 As shown, the connection channel 2022 can extend from the connection opening 2021 to the interior of the housing 20, connected to the supply pipe 214, and is designed to cooperate with the connection member 8. On the side of the connection channel 2022 opposite to the connection opening 2021, a connection element 2023 can be arranged, which can connect the end piece 75 of the steam diffusion pipe 74 accommodated in the connection member 8 to the supply pipe 214 on the one hand, and can connect the end of the wire 730 accommodated in the connection member 8 to a power source (not shown) and / or an electronic component, such as an electronic card 232 described in more detail below, which is arranged in the housing 20. Therefore, the supply pipe 214 has a first end 2141 connected to the steam generator 21 and a second end 2142 leading into the connection channel 2022 and suitable for connecting to the end piece 75. Advantageously, the connection channel 2022 extends along a longitudinal axis X1-X1 substantially parallel to the support surface 200, which facilitates the introduction of the connection member 8 through the connection opening 2021.

[0080] In order to prevent the steam from accidentally escaping from the steam diffusion base 2 through the connection opening 2021 when the steam diffusion attachment 3, 4, 5 is not connected to the base, and also to prevent liquid from entering the steam diffusion base 2 through the connection opening 2021, the closing plate 241 is pivotally mounted on the steam diffusion base 2 between an extended position and a retracted position, in which the plate closes the connection opening 2021, and in which the plate extends inside the housing 20. The pivotal mounting can be arranged, for example, on the housing 20 or inside the housing 20, usually on a wall delimiting the connection channel 2022. In this regard, in the retracted position, the closing plate 241 can advantageously be retracted into the connection channel 2022. The transition from the extended position to the retracted position is usually caused by the introduction of the connection member 8 into the connection opening 2021. It is provided that in the retracted position the closing plate 241 extends inside the housing 20 instead of outside, providing additional safety in the event of accidental extraction of the connection member 8. In fact, when the connection member 8 is withdrawn from the connection opening 2021, the closing plate 241 transitions from the retracted position to the deployed position, and with this transition, the possibility of steam escaping through the connection opening 2022 is reduced. Fig. 9The closure plate 241 is shown to comprise a first portion 2411 and a second portion 2412 opposite the first portion 2411, the first portion 2411 being arranged to ensure the pivoting of the closure plate 241, the second portion 2412 being free. In the deployed position, the first portion 2411 is advantageously closer to the support surface 200 than the second portion 2412. In other words, the panel is retracted in the housing 20 towards the support surface 200 rather than towards the delivery handle 22, which facilitates the introduction of the connection member 8 into the connection opening 2021, because the resistance provided by the closure plate 241 is low. However, this is not restrictive, as it is entirely conceivable that the plate is retracted in the housing 20 so that the second portion 2412 is away from the support surface 200. The latter configuration can be used in particular when the transition of the closure plate 241 from the retracted position to the deployed position is not controlled by the reset member 242 (which will be described in more detail below), but simply by gravity.

[0081] Advantageously, in the deployed position, the closing plate 241 closes the connection opening 2021 in a sealed manner, which makes it possible to ensure that the steam generated in the steam diffusion base 2 remains confined within the housing 20 .

[0082] Fig. 9 The presence of an advantageous stop member 243 is shown, which is designed to hold the closing plate 241 in the deployed position. In this way, there is no risk that the plate accidentally extends outside the housing 20 in the deployed position, which would jeopardize the tightness of the vapor diffusion base 2. Preferably, the stop member 243 is formed by a rib extending protrudingly in the connection channel 2022 and positioned at the connection opening 2021.

[0083] In addition, the vapor diffusion base 2 may include a reset member 242 configured to push the closing plate 241 toward the deployed position, and the connection member 8 overcomes its effect by being introduced into the connection opening 2021. The reset member 242 acts as a safety device to ensure that in the absence of stress from the connection member 8, the vapor diffusion base 2 remains substantially sealed, preventing any vapor from escaping through the connection opening 2021, and the closing plate 241 remains in the deployed position.

[0084] also, Fig. 9 and Fig.11The steam diffusion base 2 is shown to include a first locking element 261 designed to cooperate with the second locking element 8220 of the connection member 8, as described in more detail below, to prevent the connection member 8 from withdrawing from the steam diffusion base 2, typically by preventing the connection member 8 from translating 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 provides a guarantee of the correct connection of the connection member 8 to the steam diffusion base 2, usually by providing a tactile sensation, such as a click, to the user operating the household appliance 1. The first locking element 261 is preferably movable between an extended position and a retracted position, in which the blocking portion 2610 of the first locking element 261 for cooperating with the second locking element 8220 extends within the connection channel 2022, and in the retracted position, the blocking portion 2610 extends outside the connection channel 2022. The first locking element 261 can advantageously be moved by pivoting relative to the vapor diffusion base 2, and the reset element 263 advantageously pushes the first locking element 261 to the deployed position. In addition, the first locking element 261 may include an actuator 262, which is designed to be actuated by a user to convert the first locking element 261 from the deployed position to the retracted position, thereby allowing the connecting member 8 to withdraw from the vapor diffusion base 2. Fig. 9 , Fig.10 and Fig.11 It is shown that at least a portion of the actuator 262 can extend toward the exterior of the housing 20 to facilitate operation by a user.

[0085] Figure 8 It is shown that the wall defining the connection opening 2021 and on which the closing plate 241 and the actuator 262 are mounted can be formed by a component attached to the housing 20 , which facilitates the manufacture of the vapor diffusion base 2 .

[0086] See also Figure 3 The steam diffusion base 2 is advantageously powered by a cable 271 connected to the base and designed to be connected to the household power grid. To facilitate the transport and storage of the household appliance 1, the steam diffusion base 2 can be equipped with a reel 272 on which the cable 271 is mounted. The reel 272 can be passive, such as Figure 3 As shown, that is to say it can consist only of a hook on which the cable can be wound, or it can be active in a manner known per se, with means allowing the cable to be automatically wound in a cavity provided for this purpose in the vapor diffusion base 2. Supplying the vapor diffusion base 2 with power by means of the cable 271 allows in particular the operation of the electric heating resistor of the tank 210, the pump 213 of the supply circuit 212, the electronic card 232 and / or the vapor diffusion member 6, as described in more detail below. In addition, the vapor diffusion base 2 can advantageously be provided with a switch (not shown) for controlling the switching on or off of the household appliance 1.

[0087] The vapor diffusion base 2 may also include a processor, which is usually integrated in Fig. 9 In the electronic card 232 shown, the processor is configured to control the operation of the vapor diffusion base 2 and operates as a result of power being supplied to the vapor diffusion base 2 via the cable 271.

[0088] For example, the processor may control the operation of the pump 213 of the supply circuit 212 connecting the tank 210 to the reservoir 211 of the steam generator 21, or even control the opening of the solenoid valve which controls the diffusion of steam from the steam generator 21 to the supply pipe 214. The control of the solenoid valve may usually be controlled by a switch located on the steam diffusion base 2, or formed by a trigger 671 provided on the steam diffusion attachment 3, 4, 5, as described in more detail below.

[0089] Furthermore, the processor can change the temperature and / or pressure inside the steam generator 21, more precisely the temperature and / or pressure inside the tank 210, typically by controlling the behavior of the electric heating resistor. The processor can also advantageously control various parameters of the supply of the steam diffusion attachment 3, 4, 5 via the steam diffusion base 2, in particular the steam flow rate, the steam flow rate and / or the current supply of the steam diffusion attachment 3, 4, 5. When the steam diffusion attachment is an ironing attachment (typically an iron 3), regulating the supply current of the steam diffusion attachment 3, 4, 5 may be particularly useful, because this current supply controls the temperature of the heating soleplate 65 of the iron 3, which in this respect may be equipped with a thermostat; the same applies when the steam diffusion attachment is an ironing attachment 5, which may also advantageously include a heating element that operates using electrical energy. Thus, the processor is able to control the temperature of the heating soleplate 65, in particular taking into account thermal inertia effects. The processor can modify the temperature inside the steam generator 21 according to a time sequence including a temperature plateau, so as to prevent an excessive steam flow from suddenly spreading to the steam diffusion attachment 3, 4, 5. Furthermore, by varying the temperature within the steam generator 21 , the processor is configured to vary the flow rate of steam to be diffused from the steam diffusion base 2 to the steam diffusion attachments 3 , 4 , 5 .

[0090] Depending on the steam diffusion attachment 3, 4, 5 connected to the steam diffusion base 2, it may be critical to vary the steam flow rate to be diffused from the steam diffusion base 2 to the steam diffusion attachment 3, 4, 5. This is why the processor is preferably configured to place this flow rate within one of three different flow rate ranges, wherein the first of the three flow rate ranges extends from 30 g / min to 55 g / min, which corresponds to the flow rate consumed by the cleaning attachment 4, the second of the three flow rate ranges extends from 120 g / min to 180 g / min, which corresponds to the flow rate consumed by the ironing attachment 3, and the third of the three flow rate ranges extends from 120 g / min to 170 g / min, which corresponds to the flow rate consumed by the ironing attachment 5. Advantageously, this adjustment of the flow rate can also be achieved by means of a restriction element 76, which is described in more detail below.

[0091] With the aid of a processor, the operation of the vapor diffusion base 2 can be adjusted according to the vapor diffusion attachments 3, 4, 5 connected to the vapor diffusion base 2. To this end, the vapor diffusion base 2 includes a sensor (not shown), which is generally arranged in the housing 20, for example, on the side of the connection channel 2022 opposite to the connection opening 2021. The sensor is configured to measure the resistance value of the electronic component 82251 housed in the connection member 8, which will be described in more detail below. Once the vapor diffusion attachments 3, 4, 5 are connected to the vapor diffusion base 2 by the connection member 8, the sensor performs the measurement. Then, the processor is configured to control the operation of the vapor diffusion base 2 according to the resistance value recorded by the sensor. In this regard, the sensor is suitable for communicating with the processor by wire or remote means, usually through an electromagnetic network of WiFi or Bluetooth type. Therefore, in a simple, cheap, safe and fast way, multiple types of vapor diffusion attachments with the same vapor diffusion base 2 can be used.

[0092] Vapor Diffusion Accessories

[0093] like Figure 1 As shown, the vapor diffusion attachments 3 , 4 , 5 include a vapor diffusion member 6 , a cable 7 and a connecting member 8 .

[0094] Vapor diffusion components

[0095] The vapor diffusion member 6 is designed to eject the vapor generated by the vapor diffusion base 2. In this respect, once the cable 7 is connected to the vapor diffusion base 2 by the connection member 8, the vapor passes through the cable 7.

[0096] In order to adapt the steam flow generated in the steam diffusion base 2 to the steam diffusion member 6 of the steam diffusion attachment 3, 4, 5, a limiting element 76 can be provided in the connection member 8 of the steam diffusion attachment, as described in more detail below. If necessary, the household appliance 1 can include a plurality of steam diffusion attachments 3, 4, 5, at least one of which is equipped with such a limiting element 76 and at least another one is not, or more precisely, its end piece 75 (as described in more detail below) is not.

[0097] The steam diffusion attachment 3, 4, 5 is detachable as long as the connection member 8 is designed to be coupled or detached with the steam diffusion base 2. This is particularly useful for adapting the use of the household appliance 1 to the various uses sought. In fact, the use of the steam diffusion attachment 3, 4, 5 is determined by its steam diffusion member 6.

[0098] Typically, the vapor diffusion member 6 includes a gripping handle 67 from which the vapor diffusion head 61 extends. The gripping handle 67 may be integral with the vapor diffusion head 61, or may be assembled and fixed to the vapor diffusion head 61 by any suitable fixing element, such as a screw.

[0099] The grip handle 67 allows the user to manipulate the vapor diffusion member 6 and also allows the vapor diffusion accessories 3, 4, 5 to be transported when necessary. In this regard, the grip handle 67 can be equipped with a hook element 6770, such as Figure 5 and Figure 6 as well as Fig.13 As shown, for example, a surface having a higher roughness than the remainder of the grip handle 67 extends from the grip handle 67 to facilitate gripping by a user, typically by preventing the user's hand from sliding on the grip handle 67.

[0100] The gripping handle 67 may connect the cord 7 to the steam diffusion head 61 and, in some cases, such as for the cleaning attachment 4 and the ironing attachment 5, allow steam to diffuse from the cord 7 to the steam diffusion head 61. This is not restrictive in nature, as the cord 7 may be connected to any part of the steam diffusion member 6 except the gripping handle 67, which in the case of the iron 3 is typically connected to the body.

[0101] In addition, the gripping handle 67 may be equipped with a switch, typically a trigger 671, which controls the opening of the solenoid valve of the steam diffusion base 2 to allow steam to diffuse from the steam generator 21 to the steam diffusion member 6 through the cable 7. The trigger 671 is movably mounted (e.g., by pivoting) on ​​the gripping handle 67 and is connected to the electronic components, allowing the user's stress on the trigger 671 to be transmitted to the processor of the steam diffusion base 2 through the wire 730 extending in the cable 7. If necessary, the trigger 671 can be monostable, that is, it can be manually put into a pushed-in position that causes the solenoid valve to open, and automatically returns to a rest position when no pressure is applied thereto.

[0102] Especially Figure 7 As shown, the gripping handle 67 may be equipped with a hook element 674 and a guide element 675, which are respectively used to cooperate with the fixing element 20112 and the holding member 2011 arranged at the storage space 2010 of the steam diffusion base 2. The hook element 674 generally takes the form of a ring extending from the end of the gripping handle 67 opposite to the steam diffusion head 61, which allows to avoid any collision between the steam diffusion head 61 and the holding member 2011 and facilitates the storage of the steam diffusion member 6 on the steam diffusion base 2. In addition, the guide element 675 may take the form of a groove provided in the ring so as to cooperate with the rib of the fixing element 20112. This is indeed a simple, reliable and inexpensive means to manufacture. Figure 5 and Figure 6 The vapor diffusion member 6 is typically shown in a hanging position, wherein the holding member 2011 and the fixing element 20112 of the vapor diffusion base 2 cooperate with the fixing element 20112 and the hook element 674 of the gripping handle 67 of the vapor diffusion member 6, respectively.

[0103] The steam diffusion head 61 is designed to spray steam generated by the steam diffusion base 2, and its structure is suitable for the desired purpose, such as treating clothes or cleaning surfaces by ironing or pressing. Figure 1 , Figure 4 and Figure 5 The steam diffusing member 6 is shown when the steam diffusing accessory is an ironing accessory 5 for ironing laundry. Figure 2 , Figure 3 , Fig.12 and Fig.13 The steam diffusing member 6 is shown when the steam diffusing attachment is an iron 3 . Figure 6 , Fig.14 , Fig.15 , Fig.16 , Fig.17 , Fig.18 , Fig.19 and Fig. 20 The vapor diffusion member 6 is shown when the vapor diffusion accessory is a surface cleaning accessory 4 .

[0104] If necessary, especially Figure 2 and Figure 4 As shown, the steam diffusion head 61 can be equipped with a hook recess 676 that is complementary to the stopper 2013 of the steam diffusion base 2. Figure 4 In the case of the steam diffusion member 6 of the ironing attachment 5, the hook recess 676 takes the form of a groove formed at the surface of the steam diffusion head 61 opposite to the gripping handle 67, and the storage space 2010 provides a subspace 20100 at the lower end of the storage space 2010, that is, the end closest to the support surface 200 of the steam diffusion base 2, which is suitable for receiving a part of the steam diffusion head 61 to limit its volume.

[0105] Figure 2 , Figure 3 , Fig.12 and Fig.13 The steam diffusion member 6 of the ironing attachment 3 is shown to comprise a main body forming a steam diffusion head 61 and a gripping handle 67 connected to the main body.

[0106] The steam diffusion head 61 comprises a heating base plate 65 for contacting the clothes to be treated (typically clothes to be ironed). The heating base plate 65 comprises a heat conductive material, such as metal, and may also comprise a coating on its surface, which is in contact with the clothes, the coating being configured to improve sliding on the clothes and / or avoid degradation of the clothes. A plurality of steam diffusion holes ( Fig.12 In this respect, the steam diffusion head 61 comprises a diffusion circuit adapted to supply the steam diffusion holes with steam generated in the steam diffusion base 2 and transmitted by the cable 7.

[0107] Fig.12 It is also shown that the steam diffusion head 61 includes a shell 66 defining an inner cavity 660, and the heating base plate 65 is mounted on the steam diffusion head 61 so as to define a communication channel 6600 between the inner cavity 660 and the outside of the steam diffusion head 61 together with the shell 66. The shell 66 is designed to protect the components of the steam diffusion member 6. Typically, Fig.12 It is shown that the heating members 6630, 6631, 661 may be arranged within the inner cavity 660 and configured to heat the heating base plate 65. The heating members 6630, 6631, 661 are embedded in the base plate 65 and include a metal tubular element 6630, typically made of copper-containing steel, which defines the outer wall of the heating members 6630, 6631, 661, and an electrically conductive element, typically in the form of a resistive wire 661 and extending within the tubular element 6630. Furthermore, the tubular element 6630 is filled with magnesium oxide 6631, which ensures both electrical insulation of the tubular element 6630 relative to the resistive wire 661 and good thermal conduction towards the base plate 65. Furthermore, as shown in FIG. Fig.12As shown, at least a portion of the resistance wire 661 extends outside the tubular element 6630 and comprises a free end 6610 that allows it to be electrically connected to a power supply cable extending through the cable 7 .

[0108] Fig.12 Also shown is a hook recess 676 provided in the vapor diffusion member 6, more precisely provided in the vapor diffusion head 61, and cooperating with the stopper 2013 of the vapor diffusion base 2. The hook recess 676 is formed at a portion of the vapor diffusion head 61 that extends toward the ground when the vapor diffusion member 6 is in a vertical position. However, this is not restrictive, as the hook recess 676 may be provided at other portions of the vapor diffusion head 61.

[0109] In addition, if Figure 3 As shown, the portion of the steam diffusion head 61 opposite to the hook recess 676 forms a retaining portion 610 suitable for cooperating with the retaining member 2011 of the steam diffusion base 2. The shape of the retaining portion 610 is actually designed to match the shape of the inner surface of the retaining member 2011 in the unfolded position of the retaining member 2011, and the blocking of the vertical position of the steam diffusion member 6 in the storage space 2010 is caused by the inclination of the outer surface of the steam diffusion head 61 at the retaining portion 610 relative to the vertical direction.

[0110] like Fig.13 As shown, the gripping handle 67 is hollow. In other words, the gripping handle 67 comprises walls defining an inner cavity 678 extending inside the gripping handle 67. The inner cavity 678 is particularly used to house mechanical and / or electronic components that allow the stress from the trigger 671 to be transmitted to the processor of the vapor diffusion base 2 through the cable 7. This inner cavity 678 is closed by a cover 677 designed to cooperate with the walls defining the inner cavity 678. As shown in FIG. Fig.13 As shown, the cover 677 may be provided with a hook element 6770 to facilitate grasping of the grip handle 67 by the user.

[0111] Fig.13 It is also shown that, in particular due to the structural fragility that may be caused by the presence of the inner cavity 678 in the gripping handle 67, reinforcing ribs 673 may be provided, which extend within the inner cavity 678 and connect different parts of the walls that define the inner cavity 678 to each other to strengthen the structure of the gripping handle 67. The reinforcing ribs 673 can also be used to retain all or part of the mechanical and / or electronic components so that the stress of the trigger 671 movably mounted on the gripping handle 67 can be transmitted to the processor of the vapor diffusion base 2.

[0112] When the iron 3 is arranged in the storage space 2010 and another steam diffusion attachment 4, 5 is connected to the steam diffusion base 2 and is in operation, steam may be sprayed onto the iron 3, condense and enter the iron 3, which is harmful to its life.

[0113] For example, there is a risk that liquid enters the inner cavity 660 of the vapor diffusion head 61 through the communication channel 6600 between the inner cavity 660 and the outside of the body. This is why, as Fig.12 As shown, it is particularly proposed that the insulating sheath 662 surrounds at least a portion of the free portion of the resistive wire 661 extending outside the tubular element 6630. In this way, the free end 6610 of the resistive wire 661 is electrically insulated from the tubular element 6630. Therefore, if a liquid circulates at the free end 6610 of the resistive wire 661, there is no risk that the droplets will establish an arc between the free end 6611 and the tubular element 6630 made of conductive material, which defines the outer wall of the heating member 6630, 6631, 661. The insulating sheath 662 may comprise any suitable electrically insulating material, such as plastic. Furthermore, the insulating sheath 662 may have any shape and any size suitable for isolating the resistive wire 661, thereby preventing it from establishing an arc with the liquid accidentally circulating in the inner cavity 660.

[0114] In addition, a drainage system may be provided, which is configured to drain liquid from the inner cavity 660 to the outside of the vapor diffusion head 61 by gravity when the vapor diffusion member 6 is arranged in the storage space 2010, or more generally when the vapor diffusion member 6 is in a vertical position, that is, in a position where the vapor diffusion head 61 extends substantially vertically above the ground. The drainage system provides additional safety by preventing a large amount of liquid from accumulating in the vapor diffusion member 6 when the vapor diffusion member 6 is stored in the storage space 2010.

[0115] Similarly, liquids can penetrate into the inner cavity 678 of the grip handle 67, for example, through a gap separating the cover 677 from the rest of the grip handle 67, or through a gap separating the trigger 671 from the rest of the grip handle 67. Therefore, the life of moisture-sensitive components extending within the inner cavity 678 is critical. This is why, for example, Fig.13 As shown, the grip handle 67 includes a discharge system 672, which is configured to discharge liquid from the interior of the grip handle 67 to the outside of the grip handle 67 by gravity when the vapor diffusion member 6 is arranged in the storage space 2010, or more generally when the vapor diffusion member 6 is in a vertical position, that is, in a position in which the grip handle 67 extends substantially perpendicular to the ground.

[0116] like Fig.13As shown, the drainage system 672 of the gripping handle 67 may include various components. First, the drainage system 672 of the gripping handle 67 may include at least one drainage hole 6720, preferably two drainage holes 6720, which are arranged through a drainage wall 6721 of the gripping handle 67, and the drainage wall extends toward the support surface 200 when the vapor diffusion member 6 is arranged in the storage space 2010. Therefore, once the gripping handle 67 is vertically positioned, the liquid accumulated in the inner cavity 678 can be advantageously discharged from the inner cavity. In addition, as shown in FIG. Fig.13 As shown, at least one channel recess 6730 may be provided through at least one of the reinforcing ribs 673 to allow liquid to flow through the reinforcing ribs 673. Therefore, liquid cannot accumulate in different compartments formed within the inner cavity 678 between the reinforcing ribs 673.

[0117] Fig.14 , Fig.15 and Fig.16 The steam diffusion member 6 of the cleaning attachment 4 for cleaning a surface is shown. However, what is described below with reference to these figures may also be applied to the steam diffusion member 6 of the ironing attachment 5, for example Figure 1 , Figure 4 and Figure 5 The vapor diffusion member shown.

[0118] Fig.15 and Fig.16 The steam transmission hole 670 is shown to be arranged at one end of the gripping handle 67, and once the steam diffusion attachment 4 is connected to the steam diffusion base 2, steam can be diffused from the steam diffusion base 2 to the steam transmission hole 670. In fact, in this case, the gripping handle 67 constitutes an extension of the cable 7 for transmitting the steam generated in the steam diffusion base 2 to the steam diffusion head 61. Therefore, the steam transmission hole 670 is generally formed by the end of the steam diffusion pipe 74 extending in the cable 7 (and described in more detail below), and the gripping handle 67 is designed to hold this end of the steam diffusion pipe 74. As shown from Figures 17 to 20 More precisely, the steam transmission hole 670 is also provided at the end of the gripping handle 67 opposite the hook element 674 .

[0119] Fig.14 , Fig.15 and Fig.16 Also shown extending from the end of a grip handle 67 equipped with steam transmission holes 670 is a steam diffusion head 61 comprising a base 62 and a steam diffusion member 64, which is advantageously constituted by a different type of cleaning head.

[0120] Especially Fig.15 and Fig.16 As shown, the base 62 extends from the grip handle 67 at the end of the grip handle 67 which is equipped with a steam transmission hole 670.

[0121] Fig.14 The base 62 is shown to further include a coupling surface 6310, a main hole 6311, and two secondary holes 6312 disposed in the coupling surface 6310, and the secondary holes 6312 are disposed on both sides of the main hole 6311. Fig.14 In the embodiment of the present invention, the main hole 6311 and the secondary hole 6312 are preferably aligned along an axis transverse to the gripping handle 67, or even aligned in a plane transverse to the gripping handle 67. However, this is not restrictive, because the secondary hole 6312 can also be aligned in a first plane transverse to the gripping handle 67, and the main hole 6311 extends in a second plane transverse to the handle, and the second plane is farther away from the gripping handle 67 than the first plane. As described in more detail below, the relative positioning of the main hole 6311 and the secondary hole 6312 is set to ensure error-proof installation of the cleaning head 64 with the base 62.

[0122] Fig.15 The main channel 6321 is shown extending from the main hole 6311 toward the interior of the base 62 and connected to the steam transmission hole 670. Due to the main channel 6321, steam can diffuse from the steam transmission hole 670 to the main hole 6311. Advantageously, as Fig.16 As shown, the main channel 6321 has a frustoconical section 63211 located at the main aperture 6311, the section 63211 expanding toward the main aperture 6311. As described in more detail below, this expansion allows for stable fixation of the cleaning head 64 on the base 62.

[0123] In addition, two secondary channels 6322 extend from the two secondary holes 6312 toward the inside of the base 62, respectively. The main channel 6321 and the secondary channel 6312 extend in the same axial direction corresponding to the coupling / separation direction of the cleaning head 64 on the base 62. The secondary channel 6322 is used to prevent errors during the assembly of the cleaning head 64, but also allows to ensure mechanical continuity, which will be described in more detail below. In this regard, Fig.14 The anti-rotation groove 63221 is shown opening into at least one secondary channel 6322 and is also useful for the mechanical continuity of the vapor diffusion head 61 as described in more detail below.

[0124] Fig.15 and Fig.16 The base 62 is shown to include an intermediate coupling component 63 that can be removed relative to the base 62 and includes a coupling surface 6310 and multiple walls that define a primary channel 6321 and a secondary channel 6322. Fig.16It is also shown that the main channel 6321 of the intermediate coupling component 63 extends from the hollow coupling protrusion 63212, which is designed to be inserted into the end of the steam diffusion pipe 74, and at least one seal 63210 can be arranged at the interface between the steam diffusion pipe 74 and the coupling protrusion 63212, preferably an O-ring around the coupling protrusion 63212. The end of the coupling protrusion 63212 can be provided with a protrusion designed to cooperate with the inner surface of the steam diffusion pipe 74 once the coupling protrusion 63212 is inserted into the steam diffusion pipe 74 to prevent the intermediate coupling component 63 from being pulled out of the base 62. Providing the intermediate coupling component 63 reduces the manufacturing complexity of the steam diffusion head 61 without increasing the installation complexity of the steam diffusion member 6. However, this is not restrictive because the main channel 6321 and the secondary channel 6322 can be integrated with the base 62.

[0125] exist Fig.15 and Fig.16 As can be seen more precisely in FIG. 6 , the intermediate coupling member 63 advantageously comprises a plate 631 forming a coupling surface 6310 and three protuberances 632 extending from the plate 631 , each protuberance 632 comprising a wall delimiting one of the primary channels 6321 and the secondary channels 6322 . Fig.15 It is also shown that the protrusions 632 forming the secondary channel 6322 can be designed to fix the intermediate coupling component 63 to the base 62. In this regard, an attachment hole 6322 can be provided at the end of each protrusion 632 forming the secondary channel 6322 opposite the plate 631, and can be designed to face other attachment holes 633 of the base 62 to receive an attachment device (not shown), such as a screw.

[0126] Fig.14 Various cleaning heads 64 are shown designed to be removably coupled to the base 62 depending on the desired cleaning function and / or the surface to be cleaned. Fig.14 The cleaning head 64 shown on the far left in the figure is used to clean window glass or mirrors and is described in more detail below. Fig.14 The cleaning head 64 shown in the center is used to clean any type of flat surface, such as an induction plate or a countertop. Fig.14 The cleaning head 64 shown on the far right in the figure is used for cleaning grooves, such as tile joints or tap contours, and in this respect comprises a brush. In any case, the cleaning head 64 comprises a coupling element 641 and at least two pins 642.

[0127] The coupling element 641 forms a channel for steam diffusion and protrudes from the cleaning head 64. In addition, the coupling element 641 is inserted into the main channel 6321 to allow steam to diffuse through the cleaning head 64 from the main hole 6311. In this regard, Fig.14As can be seen in addition, it may be advantageous to provide at least one seal 640 arranged between the coupling element 641 and the wall of the main channel 6321, preferably an O-ring around the coupling element 641. In addition, as Fig.16 As shown, the coupling element 641 has a section transverse to its extension axis X2-X2, which is wider at the connection between the coupling element 641 and the cleaning head 64. This widening is designed to cooperate in a complementary manner with the expansion of the frustoconical segment 63211 of the main channel 6321. In this way, due to the use of the cleaning head 64, the torque stresses that may be applied in this cooperation are better absorbed, which improves the robustness of the cleaning head 64.

[0128] Each of the two pins 642 protrudes and extends from the cleaning head 64 on both sides of the coupling element 641 and is inserted into the two secondary channels 6322, respectively, to prevent the cleaning head 64 from rotating relative to the base 62 once the cleaning head 64 is coupled to the base 62. In this way, the pins 642 allow the mechanical continuity of the cleaning head 64 on the base 62 to be achieved. In addition, once the installation is completed, the pins 642 ensure the mechanical continuity of the vapor diffusion member 6. Preferably, the pins 642 are designed to prevent the cleaning head 64 from rotating relative to the base 62 around the main channel 6321 once the cleaning head 64 is coupled to the base 62. In this regard, the pins inserted into the secondary channels 6322 equipped with the anti-rotation grooves 63221 are themselves advantageously equipped with anti-rotation ribs 6422, which are designed to cooperate with the anti-rotation grooves 63221 to prevent such rotation of the cleaning head 64 relative to the base 62 around the main channel 6321 once the pins are inserted into the secondary channels 6322. In addition, as Fig.14 As shown, at least one of the pins 642, if not both pins 642, comprises at least one anchoring element 6421, for example a longitudinal rib extending radially from the pin 642, which is designed to cooperate with the wall delimiting the secondary channel 6322, in which the pin 642 is inserted, to prevent the cleaning head 64 from being accidentally withdrawn from the base 62 by the cleaning head 64 and the base 62 being disengaged along the secondary channel 6322, preferably by rubbing against the wall of the secondary channel 6322. Preferably, each of the two pins 642 has an external shape that is not complementary to the shape of the secondary channel 6322 into which the pin 642 is to be inserted, so as to allow the pin 642 to be forcibly inserted into the secondary channel 6322. In other words, the external transverse dimension of the pin 642 is greater than the internal transverse dimension of the secondary channel 6322, the concept of transverse being understood here as a plane orthogonal to the main extension direction of the pin 642. Therefore, the pin 642 is designed to be forcibly inserted into the secondary channel 6322, which enhances the mechanical coherence and robustness of the vapor diffusion member 6 despite the fact that it comprises multiple components.

[0129] The respective bases of the coupling element 641 and the pin 642 are preferably aligned along a transverse axis with the cleaning head 64. However, since each of the coupling element 641 and the pin 642 has a free end 6410, 6420 opposite to their base, the free end 6410 of the coupling element 641 advantageously extends beyond the free end 6420 of the pin 642 relative to the cleaning head 64. This, combined with the relative positioning of the primary hole 6311 and the secondary hole 6312 already described, ensures that when the cleaning head 64 is mounted on the base 62, it is the coupling element 641 that comes into contact with the primary channel 6321 before the pin 642 comes into contact with the secondary channel 6322. In this way, the mechanical continuity of the cleaning head 64 on the base 62 is gradually achieved by means of the pin 642, which facilitates the assembly of the vapor diffusion member 6.

[0130] Figures 17 to 20 Shown in more detail is the vapour diffusion member 6 of the vapour diffusion attachment 4 equipped with a cleaning head 64 for cleaning a surface, more precisely a window pane.

[0131] Especially Fig.17 As shown, the cleaning head 64 for cleaning the window glass includes a scraping element 643 , a cleaning element 644 and a diffusion channel 645 .

[0132] The scraping element 643 extends at the end of the cleaning head 64 opposite to the gripping handle 67 and allows the surface to be scraped. In addition, the scraping element 643 extends at the end of the vapor diffusion member 6 opposite to the end of the gripping handle 67 connected to the cable 7. Fig.17 As shown, the scraping element 643 comprises at least one rigid support blade 6431 and a flexible blade 6432, the rigid support blade is preferably made of metal and advantageously made of aluminum, and the flexible blade advantageously comprises silicone. Fig.17 In the arrangement shown, the support blade 6431 preferably surrounds at least a portion of the flexible blade 6432, wherein it can be seen that the portion of the flexible blade 6432 opposite the end thereof that scrapes the surface may take the form of a bulb 64320. The bulb 64320 is designed to secure the flexible blade 6432 to the support blade 6431 by being forcibly introduced into a securing groove 64310 formed by the end of the support blade 6431 secured to the cleaning head 64. This arrangement improves scraping efficiency by allowing the flexible blade 6432 to provide greater bending strength due to its retention by the support blade 6431 while having a simple and practical structure. Fig.18 The support blade 6431, flexible blade 6432, bulb 64320 and securing groove 64310 are shown designed to extend substantially transverse to the gripping handle 67 and the entire length of the cleaning head 64 in order to maximize the surface being scraped.

[0133] The cleaning element 644 that will come into contact with the surface to be cleaned can be wetted. In fact, the steam sprayed by the cleaning head 64 onto the surface to be cleaned condenses when it comes into contact with the surface, the scraping element 643 scrapes the liquid thus formed, and the cleaning element 644 wipes the liquid while rubbing the surface to clean the surface. Therefore, the cleaning of the surface is improved. In this regard, the cleaning element 644 includes an effective, cheap and lightweight microfiber fabric material.

[0134] like Fig.17 As shown, the diffusion channel 645 is connected to the steam transmission hole 670 and is open only between the scraping element 643 and the cleaning element 644. The diffusion channel 645 is actually designed to diffuse the steam from the transmission hole to the surface to be cleaned without spraying the steam through the cleaning element 644. Therefore, in operation, the cleaning element 644 is only wetted by the liquid condensed on the window glass instead of by the sprayed steam, which improves its absorption efficiency.

[0135] Figures 18 to 20 The cleaning head 64 is shown to advantageously include a transverse body 646 and a support 647 , which facilitates the manufacture and installation of the cleaning head 64 .

[0136] The transverse body 646 extends from the gripping handle 67, more precisely from the base 62, preferably transversely to the main extension direction of the gripping handle 67, so as to maximize the surface to be cleaned. The transverse body 646 can be integral with the gripping handle 67, or form a separate part that can be removed relative to the gripping handle 67, usually through the base 62. Typically, it is the transverse body 646 that includes the above-mentioned coupling element 641 and the pin 642. In addition, as Fig.18 As shown, the transverse body 646 advantageously comprises a wall 6460 which delimits a first portion of the diffusion channel 645 and surrounds the end of the coupling element 641 opening in the steam diffusion head 61. This first portion of the diffusion channel 645 extends the coupling element 641 in a rectilinear manner in the cleaning head 64. Fig.18 and Fig.19 It is also shown 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 to the transverse body 646. Preferably, a fixing member 6463, for example an elastic hook molded with the transverse body 646, allows the scraping element 643, more precisely the support blade 6431, to be fixed to the steam diffusion head 61 in order to absorb the forces to which the scraping element 643 is subjected during operation. If necessary, the support 647 can be configured to cooperate with the fixing member 6463 in order to participate in fixing the scraping element 643 to the steam diffusion head 61.

[0137] The support member 647 is configured to be detachably mounted on the transverse body 646. In this regard, a locking member 6471 may be provided, the locking member 6471 being configured to secure the support member 647 to the transverse body 646. Fig.19 As shown, the locking part 6471 preferably includes an elastic tongue equipped with a hook. The transverse body 646 may include a complementary part 6461, such as a snap-on groove, which is designed to couple to the locking part 6471 so as to keep the support 647 fixed relative to the transverse body 646 once the support 647 and the transverse body 646 are coupled to each other. In addition, the support 647 is provided to hold the cleaning element 644. More precisely, the cleaning element 644 is preferably removable and is configured to be attached and fixed to the support 647 by means of an elastic part (not shown) provided on the periphery of the cleaning element 644. In this regard, in particular as Fig.16 and Fig.17 As shown, the cleaning element 644 is designed to be fixed to 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 in more detail below is the only escape path for the steam, and all other gaps of the cleaning head 64, especially the interface between the cleaning element 644 and the support 647, are sealed to the steam. In this way, liquid generated by the condensation of steam in the cleaning head 64 cannot be sprayed out of the cleaning head 64, especially during operation of the steam diffusion member 6. In addition, as shown in FIG. Fig. 20 As shown, the support 647 advantageously comprises a wall 6470 delimiting a second portion of the diffusion channel 645, the wall 6460 being designed to abut against the wall 6470 once the support 647 is coupled to the transverse body 646. This wall 6470 is advantageously arranged so that once the cleaning head 64 is assembled to the gripping handle 67, the steam circulating in the diffusion channel 645 is diffused substantially over the entire length of the cleaning head 64 in the main extension direction of the cleaning head 64, i.e. in a direction transverse to the gripping handle 67, preferably between 60% and 90% of this length, for example 80% of this length. Thus, once the support 647 is 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 the terminal portion of the diffusion channel 645, the diffusion opening 649 allowing communication between the diffusion chamber 648 and the outside of the cleaning head 64, so as to diffuse the steam from the transmission holes to the diffusion opening 649.

[0138] Cable

[0139] Figures 1 to 7 The cable 7 is shown in the form of a tube, preferably a flexible tube. The cross section of the cable 7 in a plane transverse to the main extension direction of the stationary cable 7 may be of any suitable shape, such as circular or oval, the shape of the cable 7 being adapted to the element it is to accommodate.

[0140] The cable 7 may comprise any suitable material, preferably a material that is impermeable to liquids and gases, such as plastic. However, this is not restrictive, as the cable 7 may also comprise a textile material, preferably a braided, woven and / or knitted material.

[0141] like Figure 1 As shown, the cable 7 comprises a first end 71 designed to be coupled to the vapor diffusion member 6 and a second end 72 designed to be coupled to the connection member 8. In this regard, the vapor diffusion attachment 3, 4, 5 can be equipped with an attachment element 78 designed to prevent the cable 7 of the vapor diffusion member 6 from being pulled out. The attachment element 78 is also suitable for not restricting the movement of the cable 7 relative to the vapor diffusion member 6, so as to facilitate the operation of the vapor diffusion attachment 3, 4, 5 by the user. Figures 1 to 7 and Fig.12 As shown, the attachment element 78 can take the form of a flexible sleeve surrounding the first end 71 of the cable 7, one end of the flexible sleeve being inserted into the vapor diffusion member 6 through a ball and socket joint connection, and the other end remaining free, and the wall of the flexible sleeve being provided with a plurality of through holes to increase the flexibility of the flexible sleeve.

[0142] Furthermore, the cable 7 is hollow and is designed to house at least one electrical sheath 73 and at least one vapour diffusion duct 74 .

[0143] The preferably flexible electrical sheath 73 is designed to surround and hold at least one wire 730 extending in the cable 7 so as to isolate it from the rest of the cable 7, in particular to electrically isolate it in a liquid-tight and gas-tight manner. In this regard, the electrical sheath 73 may comprise plastic. The electrical sheath 73 is preferably flexible, having substantially the same flexibility as the cable 7, so as to accommodate the movement of the cable 7 when operating the vapor diffusion attachment 3, 4, 5. If necessary, the electrical sheath 73 also allows a plurality of wires 730 in the cable 7 to be held together. The wire 730 is designed to allow an electric current to flow between the vapor diffusion base 2 and the vapor diffusion member 6. The wire 730 itself may also be surrounded by an insulating sheath, in particular an electrically insulating sheath. The current flowing through the wire 730 may be associated with a control signal, which is typically from the trigger 671 to control the opening of the solenoid valve, or associated with electricity, which is typically from the vapor diffusion base 2 to the conductive element 661 to power the heating base 65.

[0144] The vapor diffusion conduit 74 is designed to allow the vapor generated in the vapor diffusion base 2 to flow to the vapor diffusion member 6 via the connecting member 8. In this regard, the vapor diffusion conduit 74 has a first end 741 designed to be connected to the vapor diffusion member 6. The vapor diffusion conduit 74 can take the form of a flexible tube having substantially the same flexibility as the cable 7 so as to accommodate the movement of the cable 7 when the vapor diffusion attachment 3, 4, 5 is operated, and comprises a material that is impermeable to liquids and gases, in particular a material that is impermeable to vapor, typically plastic.

[0145] like Figure 21 to Figure 27 As shown, the end piece 75 is designed to be coupled to the second end 742 of the steam diffusion pipe 74 opposite to the first end 741, so as to connect the steam diffusion pipe 74 to the steam diffusion base 2 in a detachable manner. In this way, the steam diffusion pipe 74 allows steam to diffuse from the steam generator 21 to the steam diffusion member 6. More specifically, as Fig.12 As shown, the end piece 75 is designed to extend in the connection channel 2022 when the cable 7 is connected to the steam diffusion base 2 via the connection member 8. In addition, in this configuration where the end piece 75 is inserted into the steam diffusion base 2 through the connection opening 2021, the end piece 75 is designed to be coupled to the connection element 2023 arranged on the side of the connection channel 2022 opposite to the connection opening 2022, so as to be able to receive the steam generated by the steam generator 21 via the supply pipe 214. In this regard, in particular, Fig.10 As shown, at least one seal 753, preferably an O-ring, can be arranged around the end piece 75, preferably accommodated in a groove 750 provided on the outer surface of the end piece 75, and the seal 753 is designed to cooperate with one of the connecting elements 2023 in a configuration in which the end piece 75 is inserted into the steam diffusion base 2, in order to prevent steam leakage within the connecting channel 2022.

[0146] The end piece 75 extends substantially along the longitudinal axis X3-X3 and generally has a cylindrical outer shape, for example a cylinder of revolution centered on the longitudinal axis X3-X3. In addition, the end piece 75 is hollow to allow steam to flow from the steam diffusion base 2 to the steam diffusion duct 74. More precisely, the end piece 75 comprises a wall defining a steam channel 763 extending along the longitudinal axis X5-X5 and passing through the end piece 75. Thus, Fig. 27 The channel 763 is shown extending from a first end 751 of the end piece 75, the first end being designed to be connected to the vapor diffusion base 2, to a second end 752 of the end piece 75, the first end being designed to be connected to the cable 7. Apart from the limiting element 76 described in more detail below, the channel 763 has a circular cross section over its entire length, the diameter of which is preferably greater than 4.2 mm, and advantageously between 4.2 and 5.2 mm.

[0147] according to Fig.26 and Fig. 27 , the end piece 75 includes a restriction element 76, which is preferably mechanical and configured to reduce the flow rate of steam from the steam diffusion base 2 and / or change the flow rate of steam. The mechanical restriction element 76 has the advantages of being simple and cheap to manufacture. However, this is not restrictive, because the restriction element 76 can also be electrical or electronic, for example in the form of a diaphragm with an electrically controlled variable opening. The restriction element 76 allows the flow rate and / or flow rate of the steam generated by the steam generator 21 to be adjusted according to the steam diffusion member 6 connected to the steam diffusion base 2. More precisely, the restriction element 76 is configured to reduce the steam flow rate from a flow rate between 150 and 200 g / min to a flow rate between 30 and 55 g / min. In this regard, it is advantageous that the cleaning attachment 4 of its end piece 75 includes a restriction element 76. In fact, in this way, when the processor detects a change in the steam diffusion attachment 3, 4, 5, it is not necessary to change the steam flow rate diffused from the steam generator 21 to the connection opening 2021, which simplifies the installation, manufacture and operation of the steam diffusion base 2. Furthermore, provision is made for the limiting element 76 to be arranged at the end piece 75, i.e. at the second end 742 of the vapor diffusion duct 74, instead of at the first end 741 of the vapor diffusion duct 74 or in the vapor diffusion member 6, allowing to limit the overpressure in the vapor diffusion duct 74. In any case, this limiting element 76 also improves the user safety.

[0148] Advantageously, especially Fig.26 and Fig. 27 As shown, the restricting element 76 extends in the channel 763 and has an external shape complementary to the channel 763. More precisely, the restricting element 76 can have a first portion 761 of truncated cone extending expansively toward the first end 751 of the end piece 75 and a second portion 762 of rectilinear shape extending toward the second end 752 of the end piece 75. This shape is simple and cheap to manufacture while allowing an effective reduction in the flow rate. The restricting element 76 is advantageously integral with the end piece 75, the wall of the channel 763 then forming the external shape of the restricting element 76, which facilitates the manufacture of the end piece 75 and limits the risk of the restricting element 76 being discharged from the end piece 75 under the vapor diffusion pressure. However, this is not restrictive, because the restricting element 76 can also be attached to the channel 763, usually in the form of a ring with an external shape complementary to the shape of the channel 763, and is designed to be attached and fixed to the channel 763, usually by gluing.

[0149] In order to ensure a reduced flow through the restriction element 76, a steam through hole 760 is advantageously provided through the restriction element 76, preferably from one side to the other, so as to communicate with the channel 763. This through hole 760 extends along a longitudinal axis X4-X4, preferably parallel to the longitudinal axis X5-X5 of the channel 763, and opens on the one hand to an opening at the first frustoconical portion 761 and on the other hand to an opening at the second rectilinear portion 762. Furthermore, the through hole 760 has a cross section transverse to the longitudinal axis X4-X4 of the through hole 760, which is smaller than the cross section of the channel 763. More precisely, the cross section of the through hole 760 has the shape of a disk with a diameter between 1.2 mm and 1.7 mm.

[0150] Fig. 27 It is also shown that the limiting element 76 is preferably positioned at an equal distance from the first end 751 of the end piece 75 and the second end 752 of the end piece 75, which facilitates the manufacture of the end piece 75 by molding by limiting the risk of bending of the mold (which actually includes a weak point at the limiting element 76). In addition, once the connecting member 8 is connected to the steam diffusion base 2, the limiting element 76 is designed to be preferably positioned in the steam diffusion base 2, typically within the connecting channel 2022, to ensure that the steam is confined in the event of a rupture of the limiting element 76.

[0151] Figure 21 to Figure 23 as well as Fig.26 It is shown that a reinforcing member 77 may be provided to be arranged around the second end 72 of the cable 7. Of course, the presence of the reinforcing member 77 is not always mandatory and generally depends on the type of vapor diffusion attachment 3, 4, 5. The reinforcing member 77 may be used in particular to prevent the connection member 8 from being pulled out of the second end 72. In particular, Fig.21 and Fig.26 As shown, the reinforcing member 77 extends along the longitudinal axis X6-X6 and has at least one first anti-extraction extension 7710 extending radially outwardly from the reinforcing member 77, which is preferably made of metal for structural reasons of anti-extraction, and cooperates with a complementary second anti-extraction extension 81102 of the connecting member 8, as described in more detail below. In addition, as Fig.21As shown, the reinforcing member 77 comprises at least one coil, preferably a plurality of coils, which are connected to each other 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 coil forms a first anti-extraction extension 7710. The spiral 771 provides the advantage of providing a plurality of coils 7710 in a single component, i.e. a plurality of first anti-extraction extensions distributed along the extension axis of the spiral 771. The reinforcing member 77 is preferably in the form of a tube, which is designed to be generally assembled around the second end 72 with force. If necessary, the reinforcing member 77 comprises a sheath 772, preferably made of a plastic material, which surrounds and retains the entire coil 7710.

[0152] Connecting components

[0153] The connecting member 8 is Figure 21 to Figure 26 The connection member 8 allows the steam diffusion attachment 3, 4, 5 to be detachably connected to the steam diffusion base 2, thereby allowing steam to diffuse from the steam generator 21 to the steam diffusion member 6 through the cable 7, preferably by inserting the connection member 8 through the connection opening 2021 of the steam diffusion base 2.

[0154] In this regard, the connecting member 8 may include a second locking element 8220 designed to cooperate with the first locking element 261 of the vapor diffusion base 2, as already described with reference to Fig. 9 As stated. Fig.11 As shown, the second locking element 8220 may generally take the form of a groove provided at the outer surface of the connecting member 8 , which groove will extend facing the first locking element 261 once the connecting member 8 is inserted into the connecting opening 2021 .

[0155] The connecting member 8 comprises a coupling element 81 , preferably comprises connecting elements 821 , 822 .

[0156] The coupling element 81 is designed to couple the connecting member 8 to the cable 7 , preferably by clamping the second end 72 of the cable 7 .

[0157] In a variant (not shown), the coupling element 81 is also designed to couple the connection member 8 to the vapor diffusion base 2, usually by insertion through the connection opening 2021. If necessary, it is the coupling element 81 that comprises the second locking element 8220.

[0158] Typically, the coupling element 81 has an elongated shape and extends along the longitudinal axes X7-X7, X8-X8. Fig. 22 and Fig.25 As shown, the coupling element 81 advantageously includes a clamping piece 811 and a sleeve 812 .

[0159] The clamping member 811 comprises at least two complementary parts 8110 forming a jaw designed to clamp at least a portion of the cable 7 at the second end 72. The complementary parts 8110 are elongated and extend along the longitudinal axis X7-X7. In this regard, at least one of the complementary parts 8110 advantageously comprises at least one protrusion 81101, for example Fig.24 The pin 81101 or clamping rib 81101 visible in the figure is provided to strengthen the clamping of the cable 7, and the protrusion 81101 extends from its effective surface facing the cable 7. Preferably, also as Fig.21 and Fig.24 As shown, the clamping member 811 further comprises at least one hinge element 8111, and the at least two complementary parts 8110 are connected by the hinge element 8111. In this way, the clamping member 811 is easier to operate. The hinge element 8111 and the at least two complementary parts 8110 are advantageously integral, which is easier to manufacture. Fig.21 In one embodiment, the clamping member 811 includes three complementary parts 8110, and Fig.24 In an alternative embodiment, the clamping member 811 is shown to include two complementary parts 8110.

[0160] Fig.21 It is also shown that the clamping piece 811 can be designed for clamping the reinforcement member 77. To this end, the active surface of at least one complementary part 8110 comprises at least one second anti-extraction extension 81102 protruding from the active surface, which extends facing the reinforcement member 77. The second anti-extraction extension 81102 of the clamping piece 811 is designed to cooperate with the first anti-extraction extension 7710 of the reinforcement member 77 already described when the complementary part 8110 clamps the reinforcement member 77. This allows, once the clamping piece 811 is attached to the reinforcement member 77, 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. The second anti-extraction 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 part 8110. Fig.21It is shown that the clamping member 811 may include a plurality of blocking ribs 81102 distributed along the complementary portion 8110, some of which are transverse blocking ribs 81102 extending transversely to the longitudinal axis X7-X7 of the complementary portion 8110 and designed to prevent the clamping member 811 from translating relative to the reinforcing member 77, and others are longitudinal blocking ribs 81102 extending along this longitudinal axis X7-X7 and designed to prevent the clamping member 811 from rotating relative to the reinforcing member 77, which also prevents the clamping member 811 from translating relative to the reinforcing member 77, given the presence of the screw 771 on the reinforcing member 77. The blocking ribs 81102 advantageously have dimensions adapted to those of the screw 771 so as to effectively prevent the connection member 8 from being pulled out of the cable 7. Thus, the transverse barrier rib 81102 has a radial height substantially the same as the radial depth of the space between two consecutive turns 7710 of the spiral 771, while the longitudinal barrier rib 81102 has a longitudinal length greater than or equal to the longitudinal spacing between two consecutive turns 7710 of the spiral 771. Thus, once the complementary portion 8110 is in the clamping position of the reinforcing member 77, the turns 7710 of the spiral 771 abut against the barrier rib 81102.

[0161] Fig.21 It is also shown that the clamping member 811 may also include a retaining portion 8112, which extends from at least one of the complementary portions 8110 along the longitudinal axis X7-X7 of the complementary portion 8110. The retaining portion 8112 is designed to retain the electrical sheath 73, more precisely the end of the electrical sheath 73 is designed to extend toward the vapor diffusion base 2 when the connecting member 8 is coupled to the vapor diffusion base 2. In addition, the retaining portion 8112 is designed to keep the vapor diffusion duct 74 free, more precisely the end piece 75 free. In this way, the sealing of the connecting member 8 is improved. In addition, in the event that the connecting member 8 is pulled out of the cable 7, the retaining portion 8112 helps to protect the electrical sheath 73 and therefore the wires 730 housed therein. Fig.21 As shown, the retaining portion 8112 preferably includes a wall defining a retaining channel 81120, and a portion of the electrical sheath 73 is designed to extend in the retaining channel. In addition, the retaining channel 81120 advantageously includes a bend 81121, which is designed to keep the electrical sheath 73 fixed relative to the clamp 811, particularly when the connecting member 8 is pulled out of the cable 7.

[0162] Fig.25The clamping piece 811 shown may also include a first fixing element 81103, which is designed to cooperate with the second fixing element 8121 of the sleeve 812, as described in more detail below, to keep the sleeve 812 fixed to the clamping piece 811. The first locking element 261 may take the form of a lug extending from the outer surface of the clamping piece 811, i.e., the surface opposite to the effective surface of the complementary part 8110 of the clamping piece 811, so as to cooperate with the second fixing element 8121 by snap fit. In this regard, as shown in FIG. Fig.25 As shown, the second fixing element 8121 can take the form of a flexible tongue extending from the outer surface of the sleeve 812, that is, the surface radially opposite to the surface of the sleeve 812, which contacts the clamping member 811, and the tongue is designed to cooperate with the lug of the clamping member 811 by a snap fit.

[0163] like Fig. 22 , Fig.23 and Fig.25 As shown, sleeve 812 is designed to be assembled on clamping element 811 so as to surround it by clamping it and to keep complementary portion 8110 fixed on the portion of cable 7. Sleeve 812 thus has a substantially elongated shape along longitudinal axis X8-X8.

[0164] like Fig. 22 and Fig.23 As shown, as an alternative or supplement to the snap-fitting, the sleeve 812 can be designed to be forced to fit around the clamping member 811 so as to remain fixed relative to the clamping member 811. In this case, the sleeve 812 and the clamping member 811 can advantageously be free of fixing elements 81103, 8121.

[0165] like Figures 9 to 11 As shown, the connection elements 821 , 822 cooperate with the connection opening 2021 and extend within the connection channel 2022 to couple the connection member 8 to the vapor diffusion base 2 .

[0166] In this respect, the connection elements 821, 822 are designed to be assembled to the coupling element 81 so as to surround the sleeve 812 and be removably coupled to the vapor diffusion base 2. The connection elements 821, 822 are therefore substantially elongated parts extending along the longitudinal axes X9-X9, X10-X10.

[0167] Fig. 22 , Fig.23 and Fig.24 It is shown that the connection elements 821, 822 may have multiple parts and include a longitudinal body 821 and a cover 822. However, this is not limiting as the connection elements 821, 822 may be formed entirely from a single part.

[0168] The longitudinal body 821 has a first end 8211 through which the cable 7 passes at the passage opening 8210. Furthermore, the longitudinal body 821 is designed to be assembled to the coupling element 81 by forced assembly, preferably along the longitudinal axis X7-X7, X8-X8 of the coupling element 81, so as to at least partially and preferably completely surround the coupling element 81, more precisely at least partially and preferably completely surround the sleeve 812, and extend beyond the coupling element 81 in the direction opposite to the cable 7. More precisely, the longitudinal body 821 has an elongated shape and extends along the longitudinal axis X9-X9. In this way, the coupling element 81 remains fixed on the cable 7 and is protected by the longitudinal body 821 from any external protrusions.

[0169] Furthermore, the longitudinal body 821 may include a sealing flange 8214 at the first end 8211 of the longitudinal body 821. The sealing flange 8214 extends radially toward the longitudinal axis X9-X9 and is designed to cooperate with the sealing edge 8120 of the sleeve 812 once the longitudinal body 821 is assembled around the coupling element 81, thereby forming a seal between the coupling element 81 and the longitudinal body 821. In this way, there is no risk of liquid and / or gas entering the connection member 8 via the interface between the longitudinal body 821 and the sleeve 812. Fig.26 As shown, once the coupling element 81 is clamped around the second end 72, the sealing edge 8120 is positioned at the end of the coupling element 81 closest to the vapor diffusion component 6.

[0170] In addition, if Fig.26 As shown, the longitudinal body 821 includes a second end 8212 opposite to the first end 8211, and the second end includes a sealing lip 8213, which extends over the entire periphery of the longitudinal body 821 and protrudes from the radial outer edge of the longitudinal body 821. Of course, multiple sealing lips can be provided on the outer edge. The sealing lip 8213 is designed to cooperate with at least one complementary sealing groove 8222 provided at the cover 822, as described in more detail below.

[0171] like Figures 9 to 11 As shown, the cover 822 is designed to connect the connection member 8 to the steam diffusion base 2, that is, after being introduced through the connection opening 2021, it is usually connected to the steam diffusion base 2 in a detachable manner by cooperating with the connection channel 2022. In this regard, the cover 822 is designed to be assembled to the longitudinal body 821 by assembling along the longitudinal axis X9-X9 of the longitudinal body 821, so that at least a portion of the cover 822 surrounds at least a portion of the longitudinal body 821. In addition, the cover 822 has an elongated shape and extends along the longitudinal axis X10-X10. In addition, if necessary, the cover 822 includes a second locking element 8220, which is Fig.11The illustrated approach cooperates with a first locking element 261 of the vapor diffusion base 2 .

[0172] Fig.26 The cover 822 is shown to include an outer wall 8221 having an end portion that contacts the sealing lip 8213 and in which a sealing groove 8222 is formed. Fig.23 and Fig.25 The sealing groove 8222, which can also be seen in FIG. 8 , extends over the entire periphery of the cover 822 and is designed to cooperate with the sealing lip 8213 once the cover 822 is assembled on the longitudinal body 821, so as to form a seal between the cover 822 and the longitudinal body 822. In this way, there is no risk of liquid and / or gas entering into the connection member 8 via the interface between the longitudinal body 821 and the cover 822. If necessary, multiple sealing grooves can be provided.

[0173] Fig.25 and Fig.26 It is also shown that the cover 822 may include a partition wall 8223 that defines the steam chamber 8224 and the electrical chamber 8225.

[0174] The steam chamber 8224 is designed to accommodate one end of the steam diffusion pipe 74, in particular the end piece 75, which is designed to extend inside the steam chamber 8224 when the connecting member 8 is connected to the second end 72. Therefore, the connecting member 8, more precisely the cover 822, is designed to hold the end piece 75 when the connecting member 8 is introduced into the connecting opening 2021 of the steam diffusion base 2. In this regard, Fig.26 The retaining hole 82240 is shown to be designed to pass through the wall of the cover 822, which extends facing the connecting element 2023 arranged in the bottom of the connecting channel 2022. In addition, the end piece 75 is designed to extend through the retaining hole 82240 so as to be able to cooperate with at least one of the connecting elements 2023 in order to connect the vapor diffusion pipe 74 to the supply pipe 214 of the vapor diffusion base 2. Fig.10 It is shown that at least one seal 82241, for example an O-ring, can surround the end piece 75 at the portion of the end piece 75 extending facing the retaining hole 82240. The seal 82241 has the advantage of allowing a slight lateral displacement of the end piece 75 in the retaining hole 82240, which allows the end piece 75 to be automatically aligned in the connecting element 2023 connected to the steam duct 74, and at the same time has the advantage of forming an additional sealing barrier, which in particular allows preventing steam from entering the connecting member 8 in the event of a leak at the seal 753 when the connecting member 8 is connected to the steam diffusion base 2.

[0175] In the same manner, the electrical chamber 8225 is designed to accommodate at least one end of the electrical wire 730 protruding from one end of the electrical sheath 73, for example Fig.24When the connecting member 8 is coupled to the second end portion 72, the end of each wire 730 is actually designed to extend within the electrical chamber 8225. In addition, the electrical chamber 8225 is designed to accommodate a terminal 82250 for holding the wire 730, such as Figure 21 to Figure 23 as well as Fig.25 and Fig.26 shown. Figure 21 to Figure 23 It is also shown that the electronic component 82251 can be generally arranged at the terminal 82250, and its resistance is measured by the sensor of the vapor diffusion base 2 to determine which type of vapor diffusion attachment 3, 4, 5 is connected to the vapor diffusion base 2. In addition, a sealing sleeve (not shown) can also be accommodated in the electrical chamber 8225, located between the terminal 82250 and the end of the electrical sheath 73. The sealing sleeve can surround the wire 730 and abut against the cover 822 so as to hold the wire 730 therebetween and also prevent contact between the wire 730 and the steam that has been introduced into the connection member 8. In addition, the retaining hole 82240 can be designed to pass through the cover 822, more precisely through the wall of the cover 822, which extends facing the connection element 2023 arranged in the bottom of the connection channel 2022, and the end of the wire 730 is designed to extend through the retaining hole 82240 so as to just be able to cooperate with at least one of the connection elements 2023 to connect the wire 730 to the circuit of the vapor diffusion base 2.

[0176] In order to guarantee the mechanical coherence of the connection member 8 and improve its sealing, a fixing system is provided for aligning the longitudinal axes X7-X7, X8-X8 of the coupling element 81, the longitudinal axis X9-X9 of the longitudinal body 821 and the longitudinal axis X10-X10 of the cover 822 during their assembly. In this way, the only bearing between the different parts of the connection member 8 is achieved in an axial manner, which limits the risk of radial penetration of liquids and / or gases into the connection member 8. The fixing system is also designed to keep the coupling element 81, the longitudinal body 821 and the cover 822 fixed relative to each other once they are assembled.

[0177] In this regard, the fixing system may include a support element 831, such as Fig. 22 , Fig.23 and Fig.26As can be seen. The support element 831 protrudes and extends from the cover 822 in a direction opposite to one end of the cover 822, which end is designed to cooperate with the vapor diffusion base 2. Preferably, the support element 831 extends the partition wall 8223 of the cover 822. In addition, the support element 831 is designed to cooperate with the sleeve 812 to ensure the axial support of the cover 822 on the coupling element 81 once the coupling element 81, the longitudinal body 821 and the cover 822 are assembled. Therefore, the support element 831 may include two pawls 831, which are designed to apply an axial force on the sleeve 812 and / or the clamping member 811 once the connecting member 8 is assembled, and the axial force is transmitted to the longitudinal body 821 via the sealing edge 8120 of the sleeve 812 and the sealing flange 8214 of the longitudinal body 821, and then returns to the cover 822 through the cooperation of the sealing lip 8213 and the sealing groove 8222. This stress loop improves the mechanical consistency and sealing of the connecting member 8.

[0178] Fig.26 It is also shown that the fixing system can include a plurality of rods 832, which protrude and extend from the longitudinal body 821 in the 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 pipe and the terminal 82250 for holding the electric wire 730, so as to hold the end piece 75 and / or the terminal 82250 in place relative to the longitudinal body 821. Thus, the structural coherence of the connecting member 8 is enhanced.

[0179] In addition, if Fig.23 As shown, the fixing system may further include a first threaded support 8341, for example in the form of a hollow cylinder with threads, the first threaded support extending from the longitudinal body 821 toward the cover 822 so as to be positioned facing the first hole provided in the cover 822, the first threaded support 8341 receiving the first fixing screw 835, as shown in FIG. Fig.25 As shown, the first fixing screw is designed to fix the cover 822 on the longitudinal body 821. In the same way, the second threaded support 8342 can protrude and extend from the longitudinal body 821 in the direction of the cover 822, so as to be positioned facing the second hole provided in the cover 822, and the second threaded support 8342 receives the second fixing screw 835, which is designed to fix the cover 822 on the longitudinal body 821. Fig.26 It is also shown that a third aperture 8333 can be provided through the cover 822 and connect the electrical chamber 8225 to the outside of the cover 822. A third threaded support 8343 can also be provided in the terminal 82250 so as to be positioned facing the third aperture 8333 provided in the cover 822, and the third threaded support 8343 receives a third fixing screw 835, such as Fig.25 As shown, the third fixing screw is designed to fix the terminal 82250 to the cover 822.

[0180] Assembly of connecting components

[0181] Figure 21 to Figure 25 The method of assembling the various components of the connecting member 8 is shown.

[0182] like Figure 21 to Figure 23 As shown, when present, the reinforcement member 77 is first assembled at the second end 72 opposite the vapor diffusion member 6.

[0183] Whether there is a reinforcing member 77, such as Fig.21 and Fig.24 As shown, the vapor diffusion pipe 74 and the electrical sheath 73 are arranged in the cable 7 so as to have an end extending beyond the second end 72. The electric wire 730 is accommodated in the electrical sheath 73 in advance.

[0184] The longitudinal body 821 is assembled on the second end 72 of the cable 7 and then offset towards the first end 71 of the cable 7 to await further assembly. Fig. 22 and Fig.25 As shown, the same operation is performed for the sleeve 812. In fact, these parts 821, 812 must first be arranged on the cable 7, because once the end piece 75 and the terminal 82250 are assembled to the steam pipe and the electric wire 730, respectively, it is no longer possible to arrange the longitudinal body 821 and the sleeve 812 around the steam diffusion pipe 74 and the electrical sheath 73, given their dimensions.

[0185] Once the longitudinal body 821 and the sleeve 812 are arranged around the cable 7 , the end piece 75 is fixed at the end of the vapor diffusion duct 74 extending beyond the second end 72 , and each end of the wires 730 is fixed to the terminal 82250 .

[0186] The clamping piece 811 is mounted on the second end 72 of the cable 7 and, if necessary, on the reinforcing member 77. To this end, the complementary part 8110 forming the jaws is brought to the second end 72 and then manipulated to clamp the second end 72. Fig.21 As shown, when the retaining portion 8112 is present, the free end of the electrical sheath 73 is arranged in the retaining portion 8112 so as to be retained before manipulating the complementary portion 8110 to clamp the second end 72 .

[0187] like Fig.23 As shown, the sleeve 812 is then slid along the cable 7 so as to fit around the clamping piece 811 , thereby holding it fixed by forced fitting or by snap-fitting of the locking element.

[0188] Then, especially Fig.25As shown, the longitudinal body 821 and the cover 822 are manipulated to face and contact each other along their respective longitudinal axes X9-X9, X10-X10, the rod 832 of the longitudinal body 822 cooperates with the terminal 82250, the end piece 75 and the cover 822, the sealing lip 8213 cooperates with the sealing groove 8222, and the sealing flange 8214 cooperates with the sealing edge 8120.

[0189] Finally, the fixing screw 835 is introduced through the cover 822 and all the components of the connecting member 8 are fixed to one another by tightening the fixing screw 835 in each of their threaded supports 8341 , 8342 , 8343 .

[0190] Operation of household appliances

[0191] Once the steam diffusion base 2 is assembled on one side and the individual components of the steam diffusion attachment 3, 4, 5 are assembled on the other side, the domestic appliance 1 is ready for operation.

[0192] To this end, the steam diffusion base 2 is connected to an electrical power source, typically a domestic power source, via its cable 271. The reservoir 211 is filled with water by the user.

[0193] The steam diffusion base 2 is powered, typically by actuation of a switch, and steam is generated within the tank 210 .

[0194] Before or without powering on the steam 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 in the connection channel 2022, and connects the end piece 75 and the wire 730 to the connection element 2023 arranged at the bottom of the connection channel 2022. In this way, the steam diffusion attachments 3, 4, 5 are connected to the circuit and the supply pipe 214 of the steam diffusion base 2.

[0195] If necessary, the type of vapor diffuser attachment 3 , 4 , 5 is detected by the vapor diffuser base 2 in order to adjust its operation accordingly.

[0196] To this end, once the vapor diffusion attachment 3, 4, 5 is connected to the vapor diffusion base 2 by the connecting member 8, the resistance value of the electronic component 82251 is measured. This measurement is advantageously performed by a sensor of the vapor diffusion base 2, which transmits the measurement result to the processor. Thereby, the processor implements the control of the operation of the vapor diffusion base 2 according to the measurement result.

[0197] The control mainly allows adapting the flow rate and / or flow rate of the steam to be diffused from the steam diffusion base 2 to the steam diffusion member 6. In this respect, the control advantageously comprises modifying the flow rate of steam to be diffused from the steam diffusion base 2 to the steam diffusion attachments 3, 4, 5 so as to place the flow rate within one of three different flow rate ranges. The first of the three flow rate ranges extends from 30 g / min to 55 g / min, the second of the three flow rate ranges extends from 120 g / min to 180 g / min, and the third of the three flow rate ranges extends from 120 g / min to 170 g / min. Thus, when the detected attachment is the iron 3, the control comprises adjusting the flow rate of the steam diffused from the steam diffusion base 2 so as to place the flow rate within the range of 120 g / min to 180 g / min. Furthermore, when the detected attachment is the ironing attachment 5, the control comprises adjusting the flow rate of the steam diffused from the steam diffusion base 2 so as to place the flow rate within the range of 120 g / min to 170 g / min. When the detected accessory is a steam diffusion accessory 4 for cleaning, the control may include regulating the flow rate of the steam diffused from the steam diffusion base 2 so as to place the flow rate within a range extending from 30 g / min to 55 g / min. However, preferably, when the cleaning accessory 4 is detected, the regulation of the steam flow rate is not modified, and the limiting element 76 present in the connecting member 8 itself ensures the modification of the steam flow rate to be diffused from the steam diffusion base 2 to the cleaning accessory 4, thereby placing the flow rate within the range of 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 its connection without having to wait for the tank 210 to cool.

[0198] In order to implement such a modification of the steam flow rate to be diffused from the steam diffusion base 2 to the steam diffusion attachments 3, 4, 5, it may be necessary to modify the pressure and / or temperature parameters in the steam generator 21, more precisely in the tank 210. Such a change of the steam flow rate and / or the pressure is achieved in a manner known per se by controlling the power supply to the resistor of the tank 210. Furthermore, in order to prevent an excessive steam flow rate from suddenly diffusing to the steam diffusion attachments 3, 4, 5, the control may comprise modifying the temperature in the steam generator 21 according to a time sequence comprising a temperature plateau.

[0199] As an aid, the control allows adapting the behavior of the vapor diffusion attachments 3 , 4 , 5 , more precisely the behavior of the vapor diffusion member 6 .

[0200] In this respect, the control may consist in modifying the current supply to the vapour diffusion appendages 3, 4, 5. In fact, the current flowing through the wire 730 to power the resistive wire 661 may be interrupted or not, depending on the signal emitted by the temperature sensor carried by the soleplate 65, so as to regulate the temperature of the soleplate 65 around the set point temperature.

[0201] Between two consecutive uses of the vapor diffusion attachment 3, 4, 5, or before the connection member 8 is removed from the vapor diffusion base 2, the vapor diffusion member 6 can be arranged in the storage space 2010. In this regard, the vapor diffusion member 6 can be suspended from the holding member 2011, such as Figure 5 For ironing attachment 5 or Figure 6 As shown in the figure for the cleaning attachment 4. Similarly, the vapor diffusion member 6 can cooperate with the stopper 2013 and extend substantially vertically, as shown in the figure. Figure 2 This is shown for the iron 3. In this position, if liquid is sprayed onto and enters the iron 3, the drainage system 672 allows to ensure that liquid does not remain inside the iron 3, in particular inside the gripping handle 67, thus keeping the iron 3 in good working order.

[0202] like Figure 3 and Figure 4 As shown, the vapor diffusion member 6 can be more securely retained in the storage space 2010, in particular by cooperation between the hook recess 676 of the vapor diffusion member 6 and the stopper 2013 of the vapor diffusion base on the one hand, and by unfolding the retaining member 2011 on the other hand.

[0203] Of course, once the connection member 8 is separated from the steam diffusion base 2, even if another steam diffusion attachment 3, 4, 5 is connected to the steam diffusion base 2, or even if the household appliance 1 is transported, the steam diffusion member 6 can remain in the storage space 2010. In order to prevent the cable 7 from obstructing the transport, the cable 7 can be folded and stored on the steam diffusion base 2 with the tongue 251.

[0204] In order to separate 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 feels that the connection member 8 is no longer firmly held in the connection channel 2022 and can remove the connection member 8 from the vapor diffusion base 2. The closing plate 241 is then unfolded to close the connection opening 2021 and maintain the seal of the vapor diffusion base 2. Therefore, another vapor diffusion attachment 3, 4, 5 can be connected to the vapor diffusion base 2 by its connection member 8, the other vapor diffusion attachment 3, 4, 5 can be detected, and the operation of the vapor diffusion base 2 is adapted accordingly by the processor.

[0205] The steam diffusion attachments 3, 4, 5 are actuated by the pressure of the trigger 671 so as to spray steam onto the element to be treated (clothing or surface to be cleaned). In the case of a surface such as a window glass, the steam is sprayed uniformly along the entire cleaning head 64, condensed, scraped by the scraping element 643, and then wiped by the cleaning element 644.
