Description

Title of the invention: Wrinkle-steaming device FIELD OF INVENTION

[0001] The present invention relates to the field of household appliances for laundry care, more specifically to steam ironing appliances. STATE OF THE ART

[0002] To iron or clean fabric, a portable garment steamer, commonly called a "steam iron" or "steamer" in English, can be used. Such portable devices generally include a treatment surface designed to be applied to the garment. The treatment surface is heated and advantageously includes steam distribution holes. By gliding the treatment surface over clothing or fabric, the steam jet removes creases and has a cleaning, odor-removing, and antibacterial effect, for example. These devices offer an alternative to conventional irons by allowing vertical steaming of fabric.

[0003] To further improve the efficiency of such devices, steamers have been proposed that include a suction system on the treatment surface. This ensures that the fabric is properly pressed against the heated surface, thus preventing improper use of the device. In use, the steamer is designed to be held by the user in one hand for several minutes. However, these improved devices require new components, such as a fan or a motor, which makes them heavier and more difficult to handle.

[0004] The various assembled components are generally contained within a portable case made of two molded plastic shells. Garment steamers are not very resistant to drops, which can occur during improper handling or when the device is resting on a surface. Description of the invention

[0005] One object of the invention is to provide an efficient portable garment steamer with increased shock resistance and therefore a longer lifespan.

[0006] This objective is achieved by a garment steamer having a portable unit comprising a garment steamer head and a gripping portion extending transversely to the garment steamer head, the garment steamer further comprising • an air intake circuit comprising a fan and a motor configured to drive the fan in rotation; • a steam generation system; and • a treatment surface intended to be placed in contact with a piece of textile to be steamed and having at least one steam distribution orifice connected to the steam generation system and at least one air suction orifice connected to the air suction circuit;

[0007] the steaming device being characterized in that the portable case comprises a one-piece shell forming the gripping portion and at least part of the steaming head.

[0008] Indeed, the proposed device includes various functionalities (air intake and steam projection) allowing for efficient wrinkle removal, while also being more robust against drops or impacts that may occur during use. In fact, the presence of the one-piece plastic casing absorbs shocks and thus protects the fragile components of the device, typically the motor and fan of the air intake circuit and the steam generation system. Since the casing is a single piece, it cannot split open upon impact.

[0009] The garment steamer may have the following advantageous and non-limiting characteristics, taken alone or in any technically feasible combination: • The one-piece shell includes an upper wall extending to the level of the steaming head, the upper wall delimiting a hollow volume in which the steam generation system is arranged. • The device also includes a first modular unit configured to support the treatment face and the steam generation system, the first modular unit being intended to be at least partially inserted into the hollow volume delimited by the upper wall of the monobloc shell. This allows the steam generation system to be protected by the upper wall. The device also includes a sealing gasket arranged between the first modular unit and the upper wall of the monobloc casing. This gasket is configured to create a leak-proof connection between the first modular unit and the upper wall of the monobloc casing. This ensures that all air drawn in through the appropriate port circulates within the air intake system. It also prevents liquid from entering the device from outside, except for the steam generation system. • The upper wall extends around the entire periphery of the steam generation system, the steam generation system being entirely contained within the hollow volume, and in which the air intake circuit includes an upper air circulation channel formed between the upper wall of the shell The unit is a single piece housing the steam generation system. This design cools both the high-temperature steam generation system and the upper wall of the appliance, thus reducing the risk of burns during use. The device also includes a reservoir, and the upper wall of the one-piece casing incorporates a reservoir receiving wall. This receiving wall is located opposite the treatment face relative to the steaming head and features a liquid injection port. This liquid injection port is configured for a fluid connection between the reservoir and the steam generation system. This ensures optimal weight distribution, with the weight of the reservoir counterbalancing the weight of the treatment face and the steam generation system. Furthermore, the reservoir's rearward placement allows the user to easily monitor the liquid level when the reservoir is made of a transparent material. The gripping portion comprises a handle and a base, the base being positioned opposite the steamer head relative to the handle, and including a second modular unit configured to support the motor and fan and designed to be fitted into the base. This allows for good weight distribution of the functional components within the handheld unit, and therefore improved ergonomics of the device. The one-piece casing includes a lower wall with an opening at the base, designed to allow the insertion of the second modular unit inside the portable housing. This also facilitates the assembly of the device. The opening is closed by a cover, the cover having at least one air exhaust vent connected to the air intake system. The intake air is thus vented at the base, without being directed towards the user, which improves user comfort. The second modular unit includes an added duct designed to be fitted inside the handle and to allow airflow to the fan when the motor is running. This facilitates assembly of the device and protects any electronic components located in the grip area outside the intermediate airflow channel. The attached duct extends into the handle from the base to an upper end at the level of the steamer head; the attached duct includes a sealing gasket to prevent air from passing between The added duct and the one-piece casing at the upper end ensure that all air drawn in through the appropriate opening circulates within the air intake system. This also prevents condensation outside the intermediate air circulation channel. • The second modular unit also includes control means for the garment steamer, such as an electronic circuit board, and / or a suction mode selection button, and / or a spray trigger. This makes the device easier to operate. • The device also includes a movable power button on the second modular unit, and in which the one-piece casing includes an opening through which the power button passes when the second modular unit is inserted into the handheld case. This allows for easy assembly of the second modular unit inside the handheld case. • The device includes a sealing gasket arranged between the power button and the one-piece casing, so as to prevent water from entering the portable unit. The electronic components of the control means and the motor are thus protected. • The treatment surface comprises a heated treatment plate and a plurality of air suction ports preferably arranged around the treatment plate. The application of a treatment plate heated to the appropriate temperature, combined with peripheral air suction that ensures the textile item is in contact with the treatment plate, improves the quality of the steaming and the duration for which the textile item is ironed. • The steam generation system includes a vaporization chamber in steam communication with at least one steam distribution port, the vaporization chamber being in thermal contact with the treatment plate. This allows the treatment plate to be heated simultaneously using the high temperature of the vaporization chamber and increases the compactness of the device. • The one-piece shell is made of a plastic material. This plastic material can be lightweight yet strong, as it offers a degree of flexibility. The shell can be easily formed by molding.

[0010] According to another aspect, a method for assembling a garment steamer as described above is proposed, comprising the steps of: • insertion of a first modular unit into an upper wall of the one-piece casing of the portable unit, at the level of the steaming head; • insertion of a second modular unit into a lower wall of the one-piece shell of the portable case, at the level of the gripping portion.

[0011] The method may further include a step of attaching a reservoir to the upper wall of the one-piece shell of the portable housing. DESCRIPTION OF THE FIGURES

[0012] Other features, objectives and advantages of the invention will become apparent from the following description, which is purely illustrative and not limiting, and which should be read in conjunction with the accompanying drawings on which:

[0013] Fig. 1 is a perspective view of a garment steamer according to one embodiment of the invention;

[0014] Fig. 2 is a cross-sectional view of the garment steamer of Fig. 1.

[0015] Figure 3 is an exploded view of the garment steamer of Figure 1, showing the first and second modular units.

[0016] Throughout the figures, similar elements bear identical references. DETAILED DESCRIPTION OF THE INVENTION

[0017] With reference to [Fig. 1], the garment steamer has a portable unit 3 comprising a steaming head 2 and a gripping portion extending in a direction transverse to the steaming head 2. By "transverse," it is understood that the steaming head 2 extends in a direction (axis M) that is not parallel to the principal direction (axis P) along which the gripping portion extends. Thus, axis M forms a non-zero angle with axis P, and axis M may be orthogonal to axis P, or may have a non-right angle with axis P, as in the illustrated embodiment.

[0018] The garment steamer 1 includes the feature that the portable case 3 comprises a one-piece shell forming the grip portion and at least part of the garment steamer head 2.

[0019] Typically, the gripping portion comprises a handle 31 and a base 4 opposite the steaming head 2 with respect to the handle 31. The handheld unit 3 may, in particular, have a flared shape at the base 4, i.e., be wider than at the handle 31. The handheld unit may include an upper wall formed by the one-piece casing, at the level of the steaming head 2.

[0020] Preferably, the one-piece casing is made of a plastic material. For example, the portable unit 3 can be made of polypropylene or polycarbonate. Using a lightweight and durable material helps to reduce the weight of the device and thus improves its ease of use. Since plastic is generally less expensive and easier to mold than a metal alloy, this also reduces the manufacturing cost of the device and can simplify its production. The one-piece plastic casing is, for example, obtained by molding.

[0021] When the garment steamer is in use, the handheld unit 3 is designed to be gripped by a user at the gripping portion, specifically at the handle 31 formed between the steaming head 2 and the base 4. It is intended to be operated with one hand. The handle 31 is then held by the user, with the steaming head 2 oriented towards the garment to be steamed. The handle 31 preferably has an ergonomic surface and shape to improve user comfort when operating the garment steamer.

[0022] The garment steamer includes a treatment surface intended to be placed against a piece of fabric to be steamed, and more specifically to be pressed against the fabric, typically hung on a hanger. The treatment surface is considered to correspond to a "front" end of the steamer head 2. The garment steamer 1 is then held substantially vertically. "Vertically" means that the steamer head 2 is above the gripping portion of the handheld unit 3, or that the base 4 is below the handle 31.

[0023] When not in use, the garment steamer 1 can be placed on the base 4 in its resting position. As illustrated in [Fig. 2], the portable unit 3 may include a flat underside, allowing the garment steamer 1 to be positioned vertically on the surface S. Preferably, the base 4 includes a lower surface forming a support and allowing the user to place the garment steamer 1 vertically on a flat surface, for example a table or shelf, in a so-called resting position when not in use. The flared shape of the base 4 advantageously provides stability to the unit in its resting position.

[0024] Whether in use or at rest, the garment steamer 1 can be subjected to various impacts, including drops. The presence of the one-piece casing reinforces the resistance and lifespan of the appliance by protecting the various components of the steamer head 2 and the grip portion, and prevents components from being projected outside the garment steamer, as the one-piece casing cannot, for example, split in two.

[0025] Steam generation system

[0026] The garment steamer includes a steam generation system adapted for steam emission at the treatment surface. To this end, the treatment surface has at least one steam distribution orifice 22 connected to the steam generation system, and intended to vent steam formed in the steaming head 2 at the level of the textile item to be steamed.

[0027] Preferably, the treatment surface comprises a heated treatment plate 20. The treatment plate 20 may be a metal plate, for example, made of aluminum. Applying a surface heated to a suitable temperature to the textile piece improves wrinkle removal. Such a treatment plate 20 The heating element can be heated by one or more heating elements 23 arranged in the steaming head 2 near the treatment plate 20. The treatment plate 20 can have different shapes such as, for example, a rectangular or triangular shape.

[0028] The treatment plate 20 is traversed by the steam distribution orifice 22, typically located in a central position on the treatment plate 20, so that the projected steam is distributed over the surface of the textile piece pressed against the treatment face. Preferably, the treatment plate 20 comprises a plurality of steam distribution orifices 22 distributed over its surface. The steam distribution orifices 22 may be in the form of holes or slots.

[0029] Typically, the steam generation system comprises a vaporization chamber 21, in steam communication with at least one steam distribution port 22. The vaporization chamber 21 is heated by a heating element 23. The heating element 23 is configured to heat the walls of the vaporization chamber 21, so that a liquid injected into the vaporization chamber 21 is vaporized. The vaporization chamber 21 is in steam communication with the exterior of the garment steamer at the treatment face, via the steam distribution port 22.

[0030] Preferably, the vaporization chamber 21 is in thermal contact with the treatment plate 20. This advantageously allows the treatment plate 20 to be heated via the vaporization chamber 21, which is brought to a temperature above 100°C, preferably between 140°C and 150°C. Thus, the garment steamer can be more compact and lighter. Alternatively or in addition, the heating element 23 of the steam generation system can be located near the treatment plate 20.

[0031] Preferably, the vaporization chamber 21 and the treatment plate 20 are a single unit and incorporate the heating element 23. In other words, the treatment plate 20 can be integral with the vaporization chamber 21; that is, the treatment plate 20 and the walls of the vaporization chamber 21 are made in one piece, preferably from a conductive material such as a metal alloy, typically aluminum. This allows the treatment plate 20 and the vaporization chamber 21 to be heated simultaneously, further increasing the compactness of the garment steamer 1. Of course, in an alternative embodiment not shown, the treatment plate 20 may include its own heating element, independent of the heating element 23 of the steam generation system.

[0032] Preferably, the walls of the vaporization chamber 21 are made of a metal alloy, for example aluminum. The heating element 23 may be A heating element is positioned near the vaporization chamber 21, preferably inside the walls of the vaporization chamber 21. Preferably, the heating element 23 has a power rating of 2000 W or less, preferably between 1200 and 1400 W. This allows the walls of the vaporization chamber 21 to be efficiently heated to reach the appropriate temperature for vaporizing a liquid injected into the vaporization chamber 21, while simultaneously heating the treatment plate 20.

[0033] Air suction circuit

[0034] The garment steamer 1 includes an air intake circuit. The air intake circuit is adapted to allow air to be drawn in at the level of the treatment surface. To this end, the treatment surface has at least one air intake orifice 24 connected to the air intake circuit. This allows outside air to be drawn into the garment steamer 1 when it is in use, and thus to press the textile item to be steamed against the treatment plate 20.

[0035] The air intake circuit comprises a fan 40 and a motor 41 configured to rotate the fan 40 around a shaft 42. The fan 40, forming part of the air intake circuit, draws air from the air intake port 24 at the surface being treated. Preferably, the fan 40 and the motor 41 are arranged in the base 4.

[0036] First modular unit 8

[0037] Preferably, the one-piece shell includes an upper wall extending at the level of the steaming head 2, the upper wall delimiting a hollow volume in which the steam generation system is arranged.

[0038] Preferably, the garment steamer further comprises a first modular unit 8 configured to support the treatment surface and the steam generation system. The first modular unit is intended to be at least partially inserted into the hollow space defined by the upper wall of the one-piece casing. This provides partial protection for the steam generation system against impacts. It also allows for simplified assembly of the appliance, as will be detailed later.

[0039] Typically, the upper wall formed by the one-piece shell has an open front end. For example, the open front end may be the base of a cylindrical wall, integral with the gripping portion. The first modular unit 8 may include an end piece 26 intended to be fixed at the open front end, and configured to support the processing plate 20 and the steam generation system.

[0040] Preferably, the steaming head 2 includes a sealing gasket 27 disposed between the upper wall of the one-piece shell and the first modular unit 8. Typically, the sealing gasket 27 is positioned between the open front end of the upper wall and the nozzle 26. The sealing gasket 27 is configured to create a leak-proof connection between the first modular unit and the upper wall of the monobloc housing. It prevents air from escaping into or out of the portable housing 3, particularly at the open front end. Thus, all the air drawn in through the air intake port 24 circulates within the air intake circuit around the steam generation system. The sealing gasket 27 is preferably also watertight.

[0041] Preferably, the upper wall of which extends around the entire periphery of the steam generation system. Thus, the steam generation system is entirely contained within the hollow volume, and the steam generation system is completely protected from the outside.

[0042] The air intake circuit advantageously includes an upper air circulation channel formed between the upper wall of the one-piece housing and the steam generation system. In other words, air can flow around the steam generation system, confined by the upper wall of the portable housing 3. This allows the upper wall of the portable housing 3 to be cooled by convection. Since the upper wall of the portable housing 3 is thus considerably cooled, this reduces the risk of a user unintentionally dropping the device and being burned by contact with the upper portion. The space between the plastic housing and the steam generation system allows, through deformation, for shock absorption by the upper portion, typically during a fall, and thus prevents damage to the components of the steam generation system.

[0043] Preferably, the treatment face includes a plurality of air intake ports 24. The air intake ports 24 can be arranged around the treatment plate 20, for example, around the entire circumference of the treatment plate 20. Alternatively, the air intake ports 24 can extend over several sides of the treatment plate 20. This improves the cooling of the portable housing 3 by convection, as the intake air circulates around the entire periphery of the steam generation system and thermally isolates the portable housing 3 from the steam generation system.

[0044] Preferably, the garment steamer 1 further comprises a filter grid covering the air intake 24 to filter the airflow drawn through the air intake 24. The filter grid can then cover all the air intake 24. Preferably, it is not disposed in a cavity, but is in contact with the textile during the use of the appliance. This prevents it from becoming quickly clogged by particles.

[0045] Preferably, the air suction circuit is configured to allow an air suction flow rate greater than 10 m3 / h and less than 60 m3 / h and, even more preferably, an air suction flow rate greater than 20 m3 / h and less than 50 m3 / h.

[0046] Preferably, a pump 25 is also arranged in the steaming head 2, in fluid communication with the steam generation system. Typically, the liquid is injected into the vaporization chamber 21 via the pump 25. The pump 25 is preferably located near the vaporization chamber 21, and can also be mounted on the first modular unit 8 before assembly of the first modular unit 8 onto the monobloc shell.

[0047] Second modular unit 9

[0048] As explained previously, the gripping portion may include the handle 31 and the base 4. Typically, the plastic housing includes a wall delimiting a hollow volume in which the fan 40 and the motor 41 are arranged. Thus, the motor 41 and the fan 40 are protected from impacts by the one-piece housing. The hollow volume delimits a lower air circulation channel, through which the airflow from at least one air intake orifice 24 flows when the fan 40 is rotating.

[0049] Preferably, the garment steamer further comprises a second modular unit 9 configured to support the motor 41 and the fan 40 and intended to be arranged in the base 4. This makes it easier to assemble the device, as will be described later.

[0050] Preferably, the one-piece shell includes at the base 4 a lower wall having an opening 46. The opening 46 is intended to allow insertion of the second modular unit 9 inside the portable case 2.

[0051] The opening 46 is typically located on the lower surface of the portable housing 3. The opening 46 is sized to allow the insertion of the motor 41 and the fan 40 into the lower portion from outside the device. In other words, the opening 46 is large enough to allow the passage of the second modular unit 9 supporting the components of the base 4. The motor 41 and the fan 40 are thus protected by the one-piece housing.

[0052] The opening 46 is preferably closed by a cover 45. The cover 45 can be attached to the plastic housing by any means, for example by a screw or by a mechanical system holding it in position in the opening 46. The presence of a separate cover 45 advantageously allows for cleaning the lower air circulation channel, for example, removing particles or lint that may have been drawn into the device and could obstruct the rotation of the motor 41 around its axis 42. The cover 45 also allows for the removal of This prevents the formation of faulty components after assembly and allows for maintenance of the garment steamer. This helps to increase its lifespan.

[0053] Preferably, the cover 45 has at least one air exhaust vent connected to the air intake circuit, typically to the lower air circulation channel. This at least one air exhaust vent allows the air drawn in through the air intake vent 24 to be expelled from the device.

[0054] Typically, the handle 31 formed by the one-piece shell includes a hollow volume delimiting an intermediate air circulation channel in fluid communication with the upper air circulation channel and with the lower air circulation channel. This intermediate air circulation channel allows air to circulate from the steaming head 2 to the base 4 where the fan 40 is located. Thus, the air intake circuit extends into the handle 31 of the steaming device 1.

[0055] Preferably, the second modular unit 9 includes an added duct 32 intended to be arranged inside the handle 31 and to allow airflow towards the fan 40 when the motor 41 is rotating. The intermediate airflow channel is then formed by the added duct 32 inside the handle 31.

[0056] Typically, the attached duct 32 extends in the handle 31 from the second modular unit 9 assembled in the base 4 to an upper end at the level of the steamer head 2. Preferably, the attached duct 32 includes a sealing gasket 33 disposed on the upper end, so as to prevent air from escaping outside the air circulation channel at the upper end of the duct. In other words, the sealing gasket 33 is configured to prevent air from passing between the attached duct 32 and the one-piece shell at the upper end.

[0057] The airflow from the air intake 24 in the upper air circulation channel thus passes through the intermediate air circulation channel without escaping from the steamer 1. This limits pressure losses and improves suction efficiency, and therefore the quality of the steaming. The sealing gasket 33 is preferably also watertight. This prevents condensate from flowing towards the steamer head 2, which could cause short circuits.

[0058] Control means

[0059] Preferably, the second modular unit 9 comprises control means for the steamer, including an electronic board, and / or a suction mode selection button 73, and / or a steam trigger 72. The control means are configured to control steam emission and air suction. The control means are preferably arranged on the handle 31, so that to be able to be operated by the user with the hand used to hold the steamer 1. This makes the steamer 1 more ergonomic and simple to use.

[0060] The control means are connected to an electronic board located in the base 4, which is typically attached to the second modular unit 9 intended to be inserted into the monobloc casing at the opening. The lower air circulation channel preferably has a smaller volume than the base 4, so as to leave a confined space outside the air intake circuit. The electronic board can be mounted on the second modular unit 9 before assembly inside the portable case 3, so as to be located outside the lower air circulation channel and protected by the plastic casing. This prevents short circuits.

[0061] The garment steamer 1 may include a power button 74, allowing the garment steamer 1 to be switched on. This prevents the garment from heating up as soon as it is connected to the household electrical network, thus simplifying and ensuring safe switching on and off for the user. Preferably, the power button 74 is movablely mounted on the second modular unit 9.

[0062] Typically, the base of the ignition button 74, where it contacts the second modular unit 9, is chamfered. This means that the edges of the base are beveled at a certain angle, typically 45 degrees. The second modular unit 9 may also have a corresponding chamfer. The ignition button 74 can be attached to the second modular unit 9 using screws, clips, or other fastening mechanisms. Springs or return mechanisms may advantageously be added to ensure that the ignition button 74 returns to its initial position after being pressed.

[0063] The one-piece shell preferably includes an opening for the ignition button 74 to pass through when the second modular unit 9 is inserted into the portable housing 3. Typically the ignition button 74 protrudes outside the device when the second modular unit 9 is assembled to the one-piece shell.

[0064] The chamfer can help guide the ignition button 74 into its correct position during assembly, facilitating alignment and insertion. This makes it easier to assemble the second modular unit 9 inside the portable case 3, as the ignition button is easily aligned with the handle 31 without mechanical stress. Furthermore, the ignition button 74 can provide a better grip and be more comfortable to use, thus improving the ergonomics of the device.

[0065] Preferably, the garment steamer includes a sealing gasket arranged between the power button 74 and the one-piece casing, so as to prevent water from entering the portable unit 3. This ensures the watertightness of the unit, and in particular protects the electronic board located in the confined space of the base 4.

[0066] The garment steamer 1 may include a spray trigger 72, configured to allow targeted steam distribution from at least one steam distribution orifice 22. For example, pressing the spray trigger 72 by the user can activate the pump 25 and inject liquid from the reservoir 5 into the steaming chamber 21. Water in liquid and / or vapor form can then be sprayed onto the garment to be steamed opposite the treatment plate 20, thus improving steaming efficiency. Preferably, steam is sprayed outside the garment 1 as long as the spray trigger 72 is held down by the user.Pressing the vaporization trigger 72 can also activate the motor 41, thereby rotating the fan 40 so that an airflow is drawn in through the air intake orifice 24 when the device is in suction operating mode.

[0067] Preferably, the pump 25 is configured to supply the steam generation system with a flow rate of 35 ml / min or less. This flow rate is sufficient to allow steam distribution to the textile item to be steamed. The flow rate must be limited to reduce the risk of liquid being sprayed outside the appliance, which could cause burns or damage to the textile item.

[0068] The garment steamer 1 may include, for example, a suction mode selection button 73. The suction mode selection button 73 typically allows the user to select an operating mode for the garment steamer 1. Typically, the suction mode selection button 73 can control, via the electronic board, the power supply to the motor 41 so as to modulate the rotational speed of the fan 40 and thus the flow rate of the suctioned air. Preferably, the garment steamer 1 can also operate in a mode without suction. This allows the device to be adapted to the type of textile item to be steamed.

[0069] Assembly of the device

[0070] According to another aspect, a method for assembling the garment steamer 1 as described above is proposed.

[0071] The garment steamer can be assembled simply, according to the following steps:

[0072] - insertion of a first modular unit 8 into an upper wall of the hull monobloc of the portable case 3, at the level of the steaming head 2;

[0073] - insertion of a second modular unit 9 into a lower wall of the hull monobloc of the portable case 3, at the level of the gripping portion.

[0074] The two steps can be carried out successively, in any order.

[0075] For example, the second modular unit 9 can be inserted first into the portable case 3, before the first modular unit 8 is assembled onto the case. In this embodiment, the method preferably includes a intermediate step during which an electrical connection cable 97 of the second modular unit 9 is deployed outside the portable case, so as to be connected to an electrical connector 28 of the first modular unit 8. Thus, when assembling the first modular unit 8, the electrical connection can be made automatically.

[0076] The first modular unit 8 can be mounted on the upper wall of the portable housing 3 formed by the one-piece shell, starting from the open front end, with the vapor generation system located inside the cylindrical wall. Typically, assembly can be achieved by screwing or snapping. For example, an internal surface of the upper wall of the one-piece shell includes a male plug mechanism, and a portion of the first modular unit 8 includes a female plug mechanism, the male and female plug mechanisms being designed to snap together securely. The treatment plate 20 completely covers the open front end, and the presence of the sealing gasket 27 preferably ensures a tight seal.

[0077] Alternatively, the steam generation system connected to the pump 25 can be inserted into the upper portion of the portable housing 3. Typically, the plastic housing may include flat sections forming rails for receiving the various components of the steam generation system. The treatment plate 20 can then be attached to the portable housing 3 so as to close the open end. The steam generation system is thus completely protected from the outside.

[0078] The second modular unit 9, comprising the motor 41 and the fan 40, is assembled by insertion into the one-piece housing, inside the base. The optional added duct 32 is then configured to mechanically connect the steaming head 2. This strengthens the mechanical integrity of the components after assembly.

[0079] Preferably, the handle 31 has a substantially cylindrical shape, with an internal diameter greater than the diameter of the attached duct 32. A void is thus defined between the wall of the attached duct 32 and the plastic housing at the handle 31. This allows for the passage of connectors, typically linking the device's control means to the electronic board. Advantageously, the void is confined outside the air circulation circuit, thus preventing the electronic components from being in a humid environment, as the intake air circulating in the device is laden with vapor.

[0080] The steam generation system is in fluid communication with a liquid reservoir 5, in order to generate steam from the liquid stored in the reservoir 5, typically water or a cleaning liquid solution diluted in water. Fluid communication can be conventionally achieved by a tube from the portable housing 3 connecting the pump 25 to the reservoir 5.

[0081] Preferably, the assembly method then further includes a step of fixing the reservoir 5 to the upper wall of the one-piece shell of the portable unit 3. Typically, the upper wall of the one-piece shell includes a receiving wall for the reservoir 5 opposite the treatment face with respect to the steaming head 2. The reservoir 5 can be mounted on the receiving wall for the reservoir 5, for example after assembly of the first modular unit 8 onto the steaming head 2.

[0082] The receiving wall generally includes a liquid injection port, configured to allow a fluid connection between the reservoir 5 and the vaporization system. For example, the liquid injection port is in communication with a liquid inlet channel of the pump 25. For example, the pump 25 is arranged during assembly in a central area of ​​the upper portion of the portable housing 3, between the vapor generation system and the reservoir 5.

[0083] Since the reservoir 5 is located outside the portable unit 3, it is not necessary to disassemble the device to fill the reservoir 5. The reservoir 5 preferably has a capacity of approximately 100 mL. The reservoir 5 may include a filling opening closed by a cap. The reservoir 5 preferably includes a transparent casing, defining the outer wall of the reservoir 5, equipped with a removable cap allowing the reservoir 5 to be filled. Alternatively or additionally, the reservoir 5 may be removably mounted on the portable unit 3. This allows the garment steamer to be easily refilled with liquid.

[0084] The reservoir 5 preferably includes a ball valve, configured to close when the reservoir 5 is disconnected from the portable housing 3, in order to prevent water from flowing out of the reservoir 5. Preferably, the reservoir 5 includes a vent configured to allow air to enter when the water level drops in the reservoir 5 and to prevent the reservoir 5 from being under negative pressure. Advantageously, the vent is also configured to allow air contained in the reservoir 5 to be expelled when the pressure in the reservoir 5 increases.

[0085] The garment steamer 1 is designed for easy handling and is therefore intended to have a balanced mass distribution between the steaming head 2 and the base 4. Thus, the garment steamer 1 advantageously has a center of gravity located in the handle 31, regardless of the fill level of the reservoir 5. This helps to reduce the risk of the garment falling when it is in the resting position.

[0086] Preferably, the mass of the steaming head 2 and the mass of the base 4 are each at least equal to 40% of the total mass of the steaming device 1, typically less than or equal to 1.4 kg. The steaming device 1 is thus easy easy to handle and ergonomic in that the masses of the steaming head 2 and the base 4 are substantially equivalent.

[0087] Powering the device

[0088] The garment steamer 1 can be powered by a power cord 6, designed to be plugged into a standard electrical outlet to connect the garment steamer 1 to a household electrical network. The power cord 6 operates the components of the steam generation system and the air suction circuit. In particular, it provides power to the electronic board, the motor 41, and the heating element 23.

[0089] Preferably, the power cord 6 can be attached to the portable unit 3, for example at the base, near the underside. This improves the balance and ergonomics of the device. The power cord 6 can also be detachable. Typically, the one-piece casing can include an opening for connecting the second modular unit 9 to the power cord 6.

[0090] Preferably, an electrical connection is then established with the components of the first modular unit 8, in particular with the heating element 23 of the steam generation system. As explained previously, the electrical connection cable 97 of the second modular unit 9, connected to the power cord 6, can be deployed outside the portable case 3 at the level of the steaming head 2 during a step of the assembly process. The connection cable 97 is then connected to the electrical connector 28 of the first modular unit 8, when the latter is assembled to the portable case 3.

[0091] The power cord 6 preferably has a length between 100 cm and 300 cm. This advantageously allows a user to apply the treatment plate 20 to a garment hanging on a hanger at a height greater than 1.5 meters from the ground. The power cord 6 has a limited length so as to reduce the risk of unbalancing the device.

[0092] Use of the garment steamer

[0093] The operation of the garment steamer 1 will now be described. When the user wishes to use the garment steamer 1, they fill the reservoir 5 with liquid, typically water. They connect the garment steamer 1 to the household electrical supply via the power cord 6 and then switch on the garment steamer 1 by pressing the power button 74.

[0094] The heating element 23 of the steam generation system is then supplied with electrical current so as to reach its operating temperature. Preferably, the treatment plate 20 is also heated.

[0095] When the user wishes to use the device 1 in a vertical steaming position, he brings the treatment plate 20 vertically in front of the textile piece to be steamed and then presses on the control means, for example on the vaporization trigger 72, which has the effect of operating the pump 25 and allowing the flow of liquid from the reservoir 5 to the vaporization chamber 21.

[0096] The steam produced in the vaporization chamber 21 then escapes through the steam distribution orifices 22. The steam is then diffused onto the textile piece which, combined with the heating and drying action of the treatment plate 20, allows for effective wrinkle removal.

[0097] Simultaneously, the control means can be provided to activate an air intake in combination with the steam distribution. Typically, the pressure of the steam trigger 72 drives the operation of the motor 4L. Consequently, the fan 40 is driven to rotate around the shaft 42, so that air is drawn in through the air intake orifice 24. The intake allows the textile to be pressed against the treatment surface. The steam emission combined with the intake thus optimizes the wrinkle removal. Furthermore, the air intake also promotes the drying of the portion of the textile that has just been steamed. It has been observed that this particular process allows the wrinkle removal effect to be maintained for a longer period after the textile has been treated.Advantageously, the suction control button 73 can be used to change the rotation speed of the motor 41, and thus adapt the suction airflow to the textile item to be steamed.

[0098] According to another embodiment, the control means allow the user to control the suction independently of the steam distribution control. Thus, the user could control the steam distribution alone or in combination with the suction.

[0099] During treatment, the user can move the steamer 1 in a vertical direction, for example from top to bottom, to treat all or part of the textile item. The steamer 1 can also be used occasionally in a horizontal steaming position, for example, to steam a horizontally positioned textile item by bringing the treatment surface horizontally above the textile item. For example, the textile item may be placed against a table, such as a tablecloth, or be part of a piece of furniture, such as an armchair.

[0100] The invention is not limited to the embodiment described and shown in the accompanying figures. Modifications remain possible, particularly with regard to the constitution of the various technical features or by substitution of technical equivalents, without departing from the general principles of the invention.
