[0066] The removable fragrance dispensing element 7 is configured to be inserted into and removed from the chamber 4 by a user, for example through the opening of the chamber when the removable lid 8 is removed. The removable fragrance dispensing element 7 is not permanently fixed to the chamber 4 and may be replaceable after use.

[0067] Removal of the removable fragrance dispensing element 7 may be performed manually without the use of tools. The removable fragrance dispensing element 7 may be freely placed inside the hollow interior space 5, supported by an internal surface of the chamber 4, guided by an internal structure of the chamber 4, or positioned relative to the central hollow shaft 11 when present.

[0068] The removable fragrance dispensing element 7 may be configured to cooperate with positioning features of the chamber 4, such as a support surface, a recess, a guide, or the central hollow shaft 11. In particular, the removable fragrance dispensing element 7 may be inserted around the central hollow shaft 11 or positioned above at least one lateral opening 14.

[0069] The removable fragrance dispensing element 7 may be configured to be removed independently of the chamber 4 and without disassembling the steam generator 3 or the first steam pathway 6. This removable arrangement allows replacement of the removable fragrance dispensing element 7 without dismantling the scented steam appliance 1.

[0070] For the purpose of the present disclosure, the term “removable” means that the removable fragrance dispensing element 7 is configured to be inserted into and removed from the chamber 4 by a user during normal operation of the scented steam appliance 1 , without requiring disassembly of the chamber 4 or of the steam generator 3.

[0071] The chamber 4 comprises an opening configured to provide access to the hollow interior space 5. This opening allows for the insertion and removal of the removable fragrance dispensing element 7, facilitating maintenance and replacement.P4278PC00 Specs (AOFF)

These sealing elements are configured to compress against the chamber 4 or its surrounding surfaces, creating a barrier that prevents steam from escaping. The gaskets or O-rings may be made of heat-resistant and durable materials, such as silicone orP4278PC00 Specs (AOFF)

[0084] rubber, to withstand the high temperatures and pressures associated with steam generation. This arrangement ensures that the appliance operates efficiently by maintaining consistent steam pressure and preventing energy loss or unintended release of steam.

[0085] Alternatively, the sealing means 15 may be arranged on surfaces of the chamber 4.

[0086] The removable lid 8 may be connected to an end piece 10 or be integral or be an end piece 10. Therefore, with this arrangement, the chamber 4 and the removable fragrance dispensing element 7 are positioned at the end of the overall steam flow path originating from the steam generator 3. This configuration ensures that the chamber 4 serves as the final point of steam flow before the steam exits the appliance 1 via the steam outlet 9. By situating the chamber 4 at the end of the steam path, the design optimizes the interaction between the steam and the fragrance dispensing element 7 housed within the chamber 4, as the steam remains concentrated and directed. The interaction also between the steam and other parts of the appliance along the flow path is minimized, thereby preserving the intensity and quality of the scented steam.

[0087] This arrangement also facilitates the replacement of the removable dispensing element 7 as the latter is located within the chamber 4 at the terminal end of the steam flow path, accessible through the removable lid 8. This positioning allows the user to easily access the dispensing element 7 without the need to disassemble other components of the appliance. The accessibility provided by this design ensures quick and straightforward replacement or maintenance, thereby improving user convenience and reducing downtime during operation.

[0088] The end piece 10 may also be interchangeable and take the form of different accessories, allowing the scented steam appliance 1 to adapt to various applications and user needs. For example, the end piece 10 may be configured as a diffuser for evenly dispersing scented steam into a room, a nozzle for directing steam onto specific surfaces or fabrics, or an attachment designed for therapeutic or cosmetic uses, such as facial steaming.P4278PC00 Specs (AOFF)

[0089] These interchangeable end pieces 10 can be easily connected to or detached from the appliance, providing versatility while ensuring user convenience.

[0090] In certain embodiments, the end piece 10 may include specific functional features, such as adjustable vents or perforations to control the steam flow rate and direction.

The central hollow shaft 11 may be fixed relative to the chamber 4 so as to remain stationary when the removable fragrance dispensing element 7 is inserted or removed. The central hollow shaft 11 may extend along a longitudinal direction of the chamber 4 between the first steam pathway 6 and the steam outlet 9.P4278PC00 Specs (AOFF)

[0102] The central hollow shaft 11 may be supported by one or more internal surfaces of the chamber 4, for example by a bottom wall, a side wall, or a portion of the removable lid 8 when the chamber 4 is closed. In some embodiments, the central hollow shaft 11 may be integrally formed with the chamber 4 or permanently secured thereto. The central hollow shaft 11 may define an internal steam flow path and comprise at least one lateral opening 14 allowing steam to exit the central hollow shaft 11 into the hollow interior space 5 of the chamber 4. This arrangement allows steam to circulate inside the chamber 4 while maintaining the central hollow shaft 11 in a fixed position relative to the chamber 4.

[0103] The central hollow shaft 11 may remain within the chamber 4 when the removable fragrance element 7 is removed from the chamber 4 or the hollow interior space 5.

[0104] The central hollow shaft comprises one end 12 connected to the first steam pathway 6 and a second end 13 connected to the steam outlet 9, when the removable lid 8 closes or is arranged on the chamber 4.

[0105] The central hollow shaft 11 comprise at least one opening 14, arranged on the side of the shaft 11 and being an opening in the lateral wall of the shaft. The at least one opening 14 may be elongated along the central hollow shaft 11 , on at least a portion of the latter.

[0106] The at least one opening 14 enable the steam being in the hollow space of the hollow shaft 11 to enter the chamber 4 or flow into the chamber 4 and vice-versa.

[0107] The inclusion of the central hollow shaft 11 provides a structured pathway for directing steam within the chamber 4, enhancing the efficiency of steam flow and fragrance diffusion. By connecting one end or the first end 12 of the hollow shaft 11 to the first steam pathway 6 and the other end or second end 13 to the steam outlet 9, the hollow shaft ensures that steam is properly guided through the chamber 4 during operation. The at least one opening 14, arranged on the lateral wall of the hollow shaft 11 , allows steam to flow between the hollow interior of the shaft and the chamber 4, enabling uniform circulation of steam within the chamber. This design promotes optimal interactionP4278PC00 Specs (AOFF)

[0108] between the steam and the fragrance dispensing element 7, ensuring consistent scenting of the steam.

[0109] The openings 14, which may be elongated along the central hollow shaft 11, further improve steam distribution by allowing controlled flow into and out of the chamber 4. This configuration minimizes turbulence within the chamber and ensures even exposure of the fragrance dispensing element 7 to the steam.

[0110] Additionally, the central hollow shaft 11, which may take the form of a hollow tube made of metal or other suitable materials, contributes to the structural integrity of the appliance while withstanding high temperatures and pressures generated by the steam.

[0111] By integrating the central hollow shaft 11 with openings 14, the appliance achieves a balance between efficient steam flow and effective fragrance diffusion, enhancing the performance and reliability of the scented steam appliance. This arrangement also simplifies maintenance by ensuring that the removable fragrance dispensing element 7 is easily accessible, while maintaining consistent functionality of the steam pathway.

[0112] During the operation of the scented steam applicant 1 , steam generated by the steam generator 3 is conveyed into the chamber 4 through the first steam pathway 6, which is fluidly connected to the chamber 4 or the hollow interior space 5. Upon entering the chamber 4, the steam comes into contact with the removable fragrance dispensing element 7, which is positioned within the hollow interior space 5. As the steam interacts with the fragrance dispensing element 7, it absorbs the fragrance composition contained within or released by the element, resulting in the production of scented steam. The scented steam is then directed toward the steam outlet 9, which is integrated into the removable lid 8 that closes the opening of the chamber 4. The steam outlet 9 ensures that the scented steam is efficiently expelled from the appliance, providing consistent and uniform diffusion of the fragrance.P4278PC00 Specs (AOFF)

[0113] In an embodiment, the chamber 4 is arranged in a remote module or housing separate from the base 2 and operatively connected to the base 2, which comprises the steam generator 3. The operative connection between the base 2 and the remote module may include a fluid connection, such as a conduit, tubing, or flexible hose, allowing the steam produced by the steam generator 3 to be conveyed directly to the chamber 4.
