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 plate designed to be applied to the garment. The treatment plate is heated and advantageously includes steam distribution holes. By gliding the treatment plate 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 a textile item.

[0003] However, it has been observed in this application that, in the absence of a wall against which to press the textile, the treatment plate does not exert sufficient pressure to allow for effective wrinkle removal. Consequently, wrinkle removal devices incorporating a suction system at the level of the treatment plate have been proposed, ensuring live contact with the heated surface and thus contributing to improved performance of the device.

[0004] Such devices generally operate in two states, with or without suction. They are therefore not very adaptable to different types of textiles. Indeed, thick fabrics, for example, upholstered furniture, will require more suction to be properly pressed against the heated surface. Conversely, light or delicate fabrics, for example, silk, could be damaged if the suction is too strong. Description of the invention

[0005] One object of the invention is to provide a compact and easy-to-use portable steaming device, capable of efficiently steaming different types of textile pieces, without requiring a rigid support.

[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; • 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 garment steamer being characterized in that it comprises control means configured to operate the garment steamer according to • a first operating mode in which the fan is driven to rotate at a first rotational speed, and • a second operating mode in which the fan is driven to rotate at a second rotational speed, the second rotational speed being lower than the first rotational speed,

[0008] of steam that can be distributed through at least one steam distribution orifice for each operating mode.

[0009] The proposed garment steamer combines various functionalities to ensure optimal wrinkle removal from any type of textile. The non-suction operating mode is particularly suitable when the garment is placed on a rigid surface against which the steaming plate can exert pressure. Conversely, for steaming garments suspended from a hanger, for example, operation with active suction is advantageous. The device is adjusted using the control means. During use, the device can easily switch between operating modes, allowing for simple adaptation of the steaming process to different types of textiles.

[0010] The garment steamer may have the following advantageous and non-limiting characteristics, taken alone or in any technically feasible combination: • The control means include a mode selection button with a first operating position in which the garment steamer is operated in the first operating mode, and a second operating position in which the garment steamer is operated in the second operating mode. This allows the appliance to be easily controlled according to the different possible operating modes. • The control system is also configured to operate the garment steamer in a third mode in which the fan is off. This allows the appliance to be adapted for delicate textiles or items that do not require suction, as well as when the appliance is used in a horizontal position. The controls include a mode selection button with a fan-off position, in which the garment steamer operates in its third mode. This allows for easy operation of the appliance in this third possible mode. The control means include a steam trigger configured so that pressing the trigger results in steam being distributed through at least one steam distribution orifice. This allows for the targeted application of steam through the steam distribution orifice, improving the quality of the steaming process, particularly for thick or heavily creased textiles. The treatment surface comprises a heated treatment plate, and the steam generation system includes a vaporization chamber in which a liquid is intended to be vaporized. The control means include an ignition button configured to activate a heating element for heating the treatment plate and / or the vaporization chamber. Applying a treatment plate heated to a suitable temperature improves the quality of the steaming process. The power button is separate from the mode selection button. The power button is mounted on a modular unit housed inside the portable unit. This allows for easy assembly of the control components within the portable unit. The device includes a sealing gasket between the power button and the handheld unit to prevent water from entering the unit. This protects the control mechanisms, which may contain moisture-sensitive electronic components. At least some of the controls are located on the grip. Advantageously, the selection button is positioned on the front of the grip so that the user can operate it with the index finger of the hand holding the grip. This improves the device's ergonomics. When the user holds the device at the grip, they can easily control it through the various operating modes. The device comprises an electronic board connected to the control means via an electrical wire, in which the air intake circuit includes a duct inserted into the gripping portion. This design allows for airflow from at least one air intake to the fan, with a dedicated space for the electrical cable between the portable unit and the attached duct. This space is then sealed off from the air intake circuit. This protects moisture-sensitive electronic components while providing an air intake circuit that runs throughout the entire device, ensuring good weight distribution and therefore improved ergonomics. • The portable unit includes a one-piece casing, preferably made of a plastic material. This increases the device's resistance, particularly to drops. • The steam generation system is housed in the steamer head, with the motor and fan located in the handle. This allows for good weight distribution of the functional components within the handheld unit, resulting in improved ergonomics. • The device includes a liquid reservoir and a pump; the reservoir is removablely mounted on the steamer head, and the pump is positioned between the reservoir and the steam generation system and configured to supply the steam generation system with liquid from the reservoir. This allows for easy refilling of the liquid reservoir without having to disassemble the device.

[0011] According to another aspect, a method for steaming a piece of textile to be steamed is proposed, implemented by a steaming device as described above, the method comprising the following steps: 1. arrangement of the treatment face in relation to the textile piece; 2. Steam distribution without air suction, the garment steamer being operated in the third operating mode, and / or steam distribution combined with air suction, the garment steamer being operated in the first or second operating mode; 3. Stopping the steam distribution.

[0012] Such a process allows for effective wrinkle removal from any type of textile item.

[0013] Preferably, the treatment face comprises a heated treatment plate The process, which uses a heating element, also includes a preheating step for the steamer, during which the heating element is activated and then switched off to allow the temperature of the treatment plate to stabilize. As explained previously, this further improves the quality of the steaming and the duration for which the garment will remain wrinkle-free. DESCRIPTION OF THE FIGURES

[0020] Throughout all the figures, similar elements bear identical references. DETAILED DESCRIPTION OF THE INVENTION

[0021] With reference to [Fig. 1], the garment steamer 1 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. Typically, the gripping portion includes a handle 31 and a base 4 opposite the steaming head 2 with respect to the handle 31. The handheld case 3 may typically have a flared shape at the base 4, i.e. wider than at the handle 31.

[0022] When the garment steamer 1 is used, 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 with the garment steamer.

[0023] The steaming device 1 comprises a treatment face intended to be placed against a piece of textile to be steamed, and more specifically to be pressed against the piece of textile to be steamed, typically hung on a hanger. The treatment face is considered to correspond to a "front" end of the steaming head 2. The steaming device 1 is then held substantially vertically. By " vertically » that the steaming head 2 is above the grip portion of the portable unit 3, or that the base 4 is below the handle 31.

[0024] Preferably, the portable housing 3 is made of a plastic material. For example, the portable housing 3 can be made of polypropylene or polycarbonate.

[0025] Preferably, when the steamer 1 is in its rest position, the longitudinal axis P of the handle 31 is slightly inclined forward, i.e., in the direction of the treatment surface. The steamer head 2 may have a slender shape extending along an axis M transversely to the handle 31. The front end of the steamer head 2 lies in a plane forward of the base 4. This ensures that the base 4 does not interfere with the application of the treatment surface to the textile to be steamed.

[0026] Device operating modes

[0027] Preferably, the treatment face comprises a heated treatment plate 20. This allows a heated surface to be applied to the textile piece and improves the quality of the wrinkle removal.

[0028] The garment steamer includes a steam generation system configured to generate steam 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 configured to project the steam generated by the steam generation system out of the appliance, towards the textile to be steamed. The steam generation system typically includes a vaporization chamber 21, in which a liquid is vaporized before being projected out of the appliance.

[0029] 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 at least one air intake orifice 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.

[0030] The air suction circuit includes a fan 40 and a motor 41, intended to drive the fan 40 in rotation around a shaft 42. The fan 40, forming part of the air suction circuit, allows air to be drawn in from the air suction port 24 of the steaming head 2.

[0031] The garment steamer 1 has the particularity that it includes control means configured to operate the garment steamer 1 according to - a first operating mode in which the fan 40 is driven to rotate at a first rotation speed VI, and - a second operating mode in which the fan 40 is driven to rotate at a second rotation speed V2, the second rotation speed V2 being lower than the first rotation speed VI.

[0032] Advantageously, steam can be distributed through at least one steam distribution port 22 for each operating mode.

[0033] Preferably, the air intake circuit is configured to allow an air intake flow rate greater than 10 m³ / h and less than 60 m³ / h, and even more preferably, an air intake flow rate greater than 20 m³ / h and less than 50 m³ / h. For example, the first rotation speed is between 15,000 rpm and 17,000 rpm, and allows an air intake flow rate of between 18 m³ / h and 25 m³ / h. For example, the second rotation speed is between 18,000 rpm and 21,000 rpm, and allows an air intake flow rate of between 21 m³ / h and 36 m³ / h.

[0034] Preferably, the control means are further configured to operate the steamer 1 according to a third operating mode in which the fan 40 is off. This prevents the suction from being triggered, particularly when the textile item to be steamed is especially delicate.

[0035] Preferably, the treatment face has a plurality of suction ports 24. The suction ports 24 can be arranged around the treatment plate 20, for example, around the entire circumference of the treatment plate 20. Alternatively, the air suction ports 24 can extend over several sides of the treatment face. This makes it possible to increase the achievable air suction flow rate without increasing the power of the motor 41.

[0036] Control means

[0037] The control means are preferably at least partially arranged on the gripping portion of the handheld unit 3. They are configured to control the steam emission and air intake, and more generally to operate the device 1 according to the different operating modes. The control means are advantageously located on the front face of the handle 31, so that they can be operated by the user with the hand used to hold the garment steamer 1, typically with the index finger.

[0038] Preferably, the control means include a mode selection button 73 comprising - a first operating position in which the garment steamer is operated in the first operating mode, and - a second operating position, in which the garment steamer is operated in the second operating mode.

[0039] Typically, the mode selection button 73 can drive the rotation of the motor 41 so as to modulate the rotation speed of the fan 40 around the shaft 42. This allows the use to be adapted to the type of textile item to be steamed.

[0040] Preferably, the mode selection button 73 includes a third operating position, corresponding to a ventilation stop position, in which the steamer 1 is driven in the third operating mode.

[0041] The mode selection button 73 may be a push button comprising a push head and configured to operate in the first mode when the push head is pressed through a first depress stroke, to operate in the second mode when the push head is pressed through a second depress stroke, and to operate in the third mode when the push head is pressed through a third depress stroke. Typically, the three depress strokes are progressive.

[0042] Alternatively, the mode selection button 73 can be a slider that can be positioned in three operating positions.

[0043] The different operating modes can be controlled via contactors, each operating position being associated with a separate contactor. Alternatively, the mode selection button 73 can be a sliding switch connected to a single contactor, and the circuit connecting the contactor for control according to the second operating mode includes a diode, so as to ensure that the second rotational speed is lower than the first rotational speed.

[0044] Preferably, the control means include a spray trigger 72, configured so that pressing the trigger results in steam being dispensed through at least one steam dispensing orifice 22. In other words, the spray trigger 72 is configured to allow for a point-by-point steam dispensing from at least one steam dispensing orifice 22. For example, pressing the trigger 72 by the user can actuate a pump 25 and inject liquid into the steam generation system. Water in liquid and / or vapor form can then be sprayed onto the textile item to be steamed opposite the treatment plate 20, thus improving the steaming efficiency. Preferably, steam is sprayed outside the apparatus 1 as long as the spray trigger 72 is held down by the user, provided that liquid is available.Pressing the vaporization trigger 72 can also activate the motor 41, thereby rotating the fan 40 so that a flow of air is drawn in through the air intake orifice 24.

[0045] Typically, pressure on the spray trigger 72 causes the motor 41 to operate, according to the operating mode corresponding to the operating position of the mode selection button 73. Thus, the user The user can choose an operating mode of the device before use by selecting the operating position of the mode selection button 73, then, during use of the device 1, the user can keep the vaporization trigger 72 pressed down so as to project steam while sucking in a stream of air so as to press the textile piece against the treatment face. If the mode selection button 73 is in an operating position corresponding to a suction stop, the motor 41 is not then activated by pressing the steam trigger 72.

[0046] Preferably, the garment steamer 1 includes an ignition button 74. The ignition button 74 allows the device to be switched on, i.e., the garment steamer 1 to be turned on and off. Typically, switching on the garment steamer 1 is a prerequisite to activating the steam generation system and the motor 41 by the control means.

[0047] Preferably, the ignition button 74 is configured in particular to activate a heating element (noted "EC" on the [Fig.5]) suitable for heating the treatment plate 20 and / or suitable for heating the vaporization chamber 21. This makes it possible to avoid heating the device as soon as it is connected to the domestic electrical network, and thus a simplified and safe switching on / off for the user.

[0048] The power button 74 can be located on one face of the portable housing 3, forming an upper face of the base 4, opposite the lower surface on which the device can be placed vertically, as illustrated in [Fig. 1]. Alternatively, it can be located on a side face of the portable housing 3, preferably at the handle 31.

[0049] Preferably, the ignition button 74 is movably mounted on a modular unit attached inside the portable housing 3, i.e. intended to be inserted into the portable housing 3, typically through an opening formed in the lower surface of the base 4.

[0050] Typically, the base of the ignition button 74, where it contacts the modular unit, is chamfered. This means that the edges of the base are beveled at a certain angle, typically 45 degrees. The modular unit may also have a corresponding chamfer. The ignition button 74 can be attached to the modular unit 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.

[0051] The outer wall of the portable housing 3, typically a plastic shell, preferably includes an opening for the power button 74 to pass through when the modular unit is inserted into the portable housing 3. Typically the power button 74 protrudes outside the device when the modular unit is assembled onto the portable housing 3.

[0052] 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 modular unit 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.

[0053] Preferably, the garment steamer 1 includes a sealing gasket arranged between the power button 74 and the wall of the portable unit 3, so as to prevent water from entering the portable unit 3. This ensures the watertightness of the device.

[0054] Preferably, the steamer 1 comprises an electronic board 75 connected to the control means 72, 73, 74 via connectors 76, typically one electrical wire for each button. The presence of the sealing gasket advantageously protects the electronic board located in a confined space within the base 4.

[0055] With reference to [Fig. 3], the air intake circuit may include an attached duct 32 in the handle 31 allowing the circulation of an airflow (in the direction indicated by the straight black arrows) from at least one air intake orifice 22 to the fan 40. A passageway for the electrical wire is preferably defined between the handheld unit 3 and the attached duct 32, the passageway being sealed off from the air intake circuit. Typically, the handle 31 has a substantially cylindrical shape, with an internal diameter greater than the diameter of the attached duct 32. Thus, a gap is defined between the wall of the attached duct 32 and the plastic housing at the handle 31 (delimited by a dashed line in [Fig. 3]). This allows for a passage for the connectors 76 (including the electrical wires), linking the control means of the device 1 to the electronic board 75.The empty space allowing the passage of the electrical wire is advantageously confined outside the air circulation circuit, which prevents the electronic components from being in a humid environment, as the air drawn in circulating in the device is laden with vapor.

[0056] With reference to [Fig.4] illustrating a cross-sectional view in a plane transverse to the cutting plane of [Fig.2] and containing the X axis, the electronic board 75 can be arranged in the base 4. Similarly, the base 4 can include a confined hollow space outside the air intake circuit of the base, typically outside the lower air circulation channel where the fan 40 and the motor 4L are arranged. Thus, the electronic board 75 and the connectors 76 linking it to the various control means 72, 73, 74 are protected from moisture.

[0057] Steam generation

[0058] Preferably, the treatment face includes a plurality of steam distribution orifices 22, for example distributed over the surface of the treatment plate 20. The steam distribution orifices 22 may be in the form of holes or slots.

[0059] The vaporization chamber 21 of the steam generation system can be directly connected to at least one steam distribution orifice 22, or a wall of the vaporization chamber 21 can have the steam distribution orifice 22. 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.

[0060] 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. It is thus arranged near the vapor generation system, typically in a wall of the vaporization chamber 21.

[0061] The heating element 23 can be a heating resistor. Preferably, the heating element has a power rating of 2000 W or less, preferably between 1200 W and 1400 W. This allows the vaporization chamber 21 to be heated efficiently to reach the required temperature. Furthermore, as explained previously, this allows the treatment plate 20 to be heated simultaneously, resulting in more effective wrinkle removal when the treatment plate 20 is pressed against a piece of fabric.

[0062] Preferably, the heating element 23 is controlled directly by the power button 74. The garment steamer is configured so that the heating element 23 is supplied with current as soon as the device is switched on, after pressing the power button 74. Thus, the treatment plate 20 and the vaporization chamber 21 are heated in all operating modes of the device.

[0063] 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 solution diluted in water. The fluid communication can be conventionally achieved by a tube from the portable unit 3 connecting the vaporization chamber 21 to the reservoir 5.

[0064] Preferably, the reservoir 5 is mounted on the portable housing 3 against a rear face of the steaming head 2 opposite the treatment face. In other words, the reservoir 5 is mounted against a rear face of the steaming head 2, opposite the front face of the steaming head 2 which has the treatment plate 20.

[0065] 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 reservoir 5 to be easily refilled with liquid.

[0066] 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.

[0067] The garment steamer 1 may further include a pump 25 configured to supply the steam generation system with the liquid contained in the reservoir 5. In other words, the liquid is injected into the vaporization chamber 21 via the pump 25. The pump 25 is configured to circulate the liquid contained in the reservoir 5 to the vaporization chamber 21, i.e., to supply the steam generation system with the liquid contained in the reservoir 5. Preferably, the pump 25 is arranged between the reservoir 5 and the steam generation system.

[0068] Preferably, the pump 25 can be activated when the user presses the vaporization trigger 72, so that liquid is injected into the vaporization chamber 21 and then steam is projected through the steam distribution orifice 22. This allows the device to be adapted on an ad hoc basis, for example to remove a very pronounced crease from the textile piece.

[0069] 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.

[0070] Heating plate

[0071] The treatment plate 20 is preferably metallic, for example made of aluminum. As explained previously, applying a surface heated to a suitable temperature to the textile piece improves the wrinkle removal. The treatment plate 20 can be heated by one or more heating elements arranged in the steaming head 2 near the treatment plate 20, preferably by the heating element 23. The treatment plate 20 can have different shapes such as, for example, a rectangular or triangular shape.

[0072] 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, in particular aluminum. This allows the treatment plate 20 and the vaporization chamber 21 to be heated simultaneously, and further increases the compactness of the garment steamer 1.

[0073] Assembly of the device

[0074] Preferably, the portable housing 3 comprises a one-piece shell, formed for example from a plastic material. The one-piece shell forms an outer wall of the device and protects the device's functional components from shocks and drops.

[0075] Typically, the steam generation system can be arranged in the steaming head 2, for example, inserted at least partially into an upper portion of the one-piece shell. For example, the steam generation system and the pump 25 are arranged inside a cylindrical wall extending transversely to the gripping portion 31, and molded at the same time as the gripping portion.

[0076] Preferably, the device 1 includes a nozzle 26 configured to support the treatment plate 20, the pump 25, and the steam generation system. The nozzle 26 can thus be inserted into the steaming head so that the treatment face covers the open front end formed by the one-piece housing, at the level of the steaming head 2. The air intake circuit can be delimited in the steaming head 2 by the one-piece housing and the nozzle 26, i.e., the outer wall of the portable housing 3 forms an upper air circulation channel around the periphery of the steam generation system and the pump 25.

[0077] Preferably, the steaming head 2 includes a sealing gasket 27 disposed between the outer wall of the portable housing 3 at the steaming head 2 and the nozzle 26, for example arranged downstream of the treatment face, inside the steaming head 2. The sealing gasket 27 is configured to prevent air from escaping outside the upper air circulation channel, at the open front end of the steaming head closed by the nozzle 26. Thus, all the air drawn in through the air intake orifice 24 circulates in the air intake circuit around the steam generation system and the pump 25.

[0078] Preferably, the fan 40 and the motor 41 are arranged in the gripping portion, for example in the base 4. This makes the device 1 more balanced and ergonomic. Furthermore, the air intake circuit thus extends from at least one intake port 24 of the steaming head 2 to the base 4.

[0079] The garment steamer 1 preferably includes at least one air exhaust port in fluid communication with the air intake circuit, allowing the air drawn in through the air intake port 24 to be expelled from the device. This at least one air exhaust port is typically connected to the lower air circulation channel.

[0080] Powering the device

[0081] 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. The electronic board 75 is also powered when the garment steamer 1 is switched on.

[0082] Preferably, the power cord 6 can be fixed to the base 4. The power cord 6 can be removable.

[0083] The power cord 6 preferably has a length greater than 200 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.

[0084] Use of the garment steamer

[0085] 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.

[0086] 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 during a preliminary ignition step of the steamer 1. Preferably, the electronic board 75 is configured so that the heating element 23 is activated, i.e., supplied with electrical current for a fixed preheating time, and then switched off for a temperature homogenization time of the treatment plate 20. After the temperature homogenization time has elapsed, the electronic board 75 is preference configured to supply the heating element 23 with electrical current continuously.

[0087] The described steaming device is advantageously used to steam a piece of textile. With reference to [Fig. 5], the steaming process includes a step SI of positioning the treatment surface opposite the piece of textile, typically the treatment plate 20 against the piece of textile. When the user wishes to use the device 1 in a vertical steaming position, they bring the treatment plate 20 vertically opposite the piece of textile to be steamed. The steaming device 1 can also be used occasionally in a horizontal steaming position, for example, to steam a piece of textile positioned horizontally by bringing the treatment surface horizontally above the piece of textile. For example, the piece of textile may be placed against a table, such as a tablecloth, or be part of a piece of furniture, such as an armchair.

[0088] During a step S2, the user can operate the steamer 1 in the selected operating mode, i.e. with steam distribution without air suction, if he selects the third operating mode, and / or with steam distribution combined with air suction, if he selects the first or second operating mode.

[0089] The control means advantageously allow the user to control the suction independently of the steam distribution control in the third operating mode. Thus, the user could control the steam distribution alone (third operating mode) or in combination with the suction (first and second operating modes). The control means enable the activation of air suction in conjunction with the steam distribution.

[0090] Typically, the pressure of the steam trigger 72 causes the motor 41 to operate, according to the operating mode configured by the control means. As a result, the fan 40 is driven to rotate around the shaft 42, so that air is drawn in through the air intake 24. The intake forces the textile piece onto the treatment plate 20. The steam emission combined with the intake thus improves the wrinkle removal. Furthermore, the air intake also promotes drying of the portion of the textile piece that has just been steamed. It has been found that this particular process allows the wrinkle removal effect to be maintained for a longer period after the textile piece has been treated. The intake control button 73 can be used before or during the wrinkle removal of the textile piece.The fan's rotation speed, and therefore the airflow drawn in through at least one suction port 24, can thus be modified according to the chosen operating mode.

[0091] Preferably, the user can press the control means, for example the vaporization trigger 72, to operate the pump 25 and allow the flow of liquid from the reservoir 5 to the vaporization chamber 21. 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.

[0092] During the treatment, the user can move the steaming device 1 in a vertical direction, for example from top to bottom, to treat all or part of the textile piece.

[0093] During a step S3, the steam distribution is stopped. The steam distribution is stopped by various factors, for example, but not limited to, when the reservoir 5 is empty, when the user releases pressure on the vaporization trigger 72, or when the user switches the device off by pressing the power button 74 again or by unplugging the power cord 6. The heating element 23 is switched off and ceases to heat the vaporization chamber 21 and / or the treatment plate 20.

[0094] The user can then place the garment steamer 1 on a flat surface in the resting position.

[0095] 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.
