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] However, it has been observed that the user does not sufficiently stretch the garment or press the treatment plate firmly against it, thus limiting the effectiveness of the garment steamer. Consequently, garment steamers incorporating a suction system at the treatment plate have been proposed. This ensures that the fabric is properly stretched against the heated surface and improves the steaming process. These improved devices, however, require new components, such as a fan or motor, which increases the weight and noise, reducing user comfort. These components are also sensitive to humidity and can lead to premature malfunction of the device.Furthermore, the suction of air laden with vapor can also lead to the suction of small particles of fabric or lint, which may clog the suction circuit or prevent the fan from rotating, and therefore again cause premature malfunction of the device. Description of the invention

[0004] One object of the invention is to provide a portable garment steamer that is ergonomic and comfortable to use, i.e. less noisy and lighter, and allows for effective steaming for a long period of use.

[0005] This objective is achieved by a garment steamer having a portable unit comprising a steaming head and a gripping portion extending in a direction transverse to the steaming head, the gripping portion comprising a handle and a base, the base being opposite the steamer head in relation to the handle, the steamer also comprising: - an air intake circuit comprising a fan and a motor configured to drive the fan in rotation around an axis of rotation, the fan and the motor being arranged in the base; - 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;

[0006] the garment steamer being characterized in that the air suction circuit includes an intermediate channel extending in the handle along a longitudinal axis not coinciding with the axis of rotation, so as to form in the air suction circuit a change in the direction of airflow upstream of the fan and the motor.

[0007] The proposed garment steamer includes air intake and steam distribution functionalities at the treatment plate level, enabling effective garment steaming. The air intake circuit extends from the steaming head, where the air intake port is located, to the base where the actuators are positioned, via an intermediate channel in the handle. The handle extends along an axis advantageously inclined forward relative to the motor's axis of rotation in the base. This results in a more ergonomic garment steamer. Furthermore, the offset of the intermediate channel relative to the motor's axis of rotation allows for a deflection of the steam-laden airflow, thus diverting any condensation carried by the steam, due to its inertia, to a dedicated area before it reaches the motor.The environment around the motor and fan is therefore less humid, which helps to increase their lifespan.

[0008] The garment steamer may have the following advantageous and non-limiting characteristics, taken alone or in any technically feasible combination: • The longitudinal axis is inclined forwards towards the treatment face, preferably forming an angle between 10° and 15° with the axis of rotation. • The base includes a flat lower surface on which the garment steamer is intended to rest, with the axis of rotation perpendicular to the flat lower surface. This ensures a stable position when the appliance is not in use, without the treatment surface coming into contact with the surface on which the appliance rests. The air intake circuit further includes a connecting channel extending from the fan to the handle along an intermediate axis, the intermediate axis being inclined towards the rear of the steamer head relative to the axis of rotation. The air intake system includes a storage area for solid particles and / or condensate present in the air intake circuit. This storage area is located as an extension of the intermediate channel, between the connecting channel and the portable unit. This design retains any lint or other textile particles that could clog the air intake system and cause the device to malfunction. The portable unit includes an opening positioned opposite the storage area, which is closed by a removable lid. This allows for cleaning the storage area by removing any solid particles and / or condensation that may be trapped there. The air intake system comprises, at the base, a central air circulation channel extending along the axis of rotation, in which the motor is mounted; and a peripheral air circulation channel, concentric with the central air circulation channel and connected via fluid to an air exhaust port. The fan is configured to draw air from the air intake port to the air exhaust port, through the peripheral air circulation channel. This prevents the vapor-laden airflow from the air intake port from circulating around the motor. The device also includes a protective element centered on the motor's axis of rotation so as to cover the central air circulation channel. This protective element is configured to direct an airflow from the intermediate channel to the peripheral air circulation channel. This protects the motor from airflow that may be laden with vapor, and from liquid resulting from condensation in the air intake circuit. The base includes at least one cooling air inlet and at least one cooling air outlet, the at least one air inlet and at least one air outlet being connected to the central air circulation channel. The garment steamer further includes a cooling fan arranged in the base and configured to be driven in rotation by the motor around its axis of rotation, so as to draw an airflow into the central air circulation channel from the at least one cooling air inlet to the at least one cooling air outlet. This allows to cool the motor and thus prevent premature wear of the device due to overheating. • The base includes a lower surface, with at least one cooling air outlet arranged on this lower surface and opening into the central air circulation channel. The cooling fan is positioned between the motor and the lower surface in such a way as to prevent liquid from passing from the cooling air outlet to the motor. The intake air is thus expelled at the base, without being directed towards the user, which improves user comfort. The motor is protected from any liquid splashes that could impair its operation. DESCRIPTION OF THE FIGURES

[0009] 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:

[0010] Fig. 1 is a perspective view of a garment steamer according to a certain embodiment.

[0011] Fig. 2 is a cross-sectional view of the garment steamer.

[0012] Figure 3 is a perspective view of a conduit inserted in the handle of the garment steamer.

[0013] Fig. 4 is a cross-sectional view of the base of the garment steamer.

[0014] Throughout the figures, similar elements bear identical references. DETAILED DESCRIPTION OF THE INVENTION

[0015] 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.

[0016] The gripping portion includes a handle 31 and a base 4 opposite the steaming head 2 with respect to the handle 31. The portable case 3 can typically have a flared shape at the base 4, i.e. wider than at the handle 31.

[0017] When the garment steamer is used, the handheld unit 3 is intended to be gripped by a user at the gripping portion, in particular at the handle 31 formed between the steaming head 2 and the base 4. It It is designed 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.

[0018] 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.

[0019] Preferably, the treatment surface may include a treatment plate 20, for example, a heating plate. Applying a surface heated to a suitable temperature to the textile improves the steaming process. The treatment plate 20 is preferably metallic, for example, made of aluminum. It may be heated by one or more heating elements arranged in the steaming head 2, for example, inside the steaming head 2, against the treatment plate 20. The treatment plate 20 may have various shapes, such as, for example, a rectangular or triangular shape.

[0020] Preferably, when not in use, the garment steamer 1 can be placed on the gripping portion, typically on the base 4, in its resting position. As illustrated in [Fig. 2], the portable case may include a flat lower surface, allowing the garment steamer 1 to be positioned vertically on the surface S. The flat lower surface thus forms a support enabling the user to place the garment steamer 1 vertically on a table or shelf, in a so-called resting position, when not in use.

[0021] The garment steamer 1 includes a steam generation system. The steam generation system is adapted to allow steam to be emitted at the level of the treatment plate 20. To this end, the treatment face has at least one steam distribution orifice 22, intended to vent steam formed in the steamer head 2 at the level of the textile item to be steamed.

[0022] The steamer 1 includes an air suction circuit. The air suction circuit is adapted to allow air to be drawn in at the level of the treatment plate 20. To this end, the treatment face has at least one air suction orifice 24, allowing outside air to be drawn in to the steamer 1 when it is in use, and thus keeping the textile item to be steamed under tension against the treatment plate 20.

[0023] With reference to [Fig. 2], the air intake circuit comprises a fan 40 and a motor 41 for driving the fan 40 in rotation around a shaft 42 parallel to an axis of rotation X. The fan 40 and the motor 41 are arranged in the base 4. The fan 40, forming part of the air intake circuit, allows air to be drawn from the air intake port 24 of the steamer head 2 to the base 4.

[0024] The garment steamer 1 has the distinctive feature that the air intake circuit includes an intermediate channel extending into the handle 31 along a longitudinal axis P that does not coincide with the axis of rotation X, so as to create a change in the direction of airflow in the air intake circuit upstream of the fan 40 and the motor 4L. In other words, several configurations are possible: the longitudinal axis P and the axis of rotation X may be parallel but offset. The air intake circuit may then include a connecting portion joining the intermediate channel and the space where the fan 40 is located. The longitudinal axis P and the axis of rotation X may intersect directly; for example, the longitudinal axis P forms a non-zero angle with the axis of rotation X, and the intermediate channel extends to the space where the fan 40 is located.Finally, the longitudinal axis P and the rotation axis X may be non-parallel, but without intersection in the air intake circuit, so that the air intake circuit may include a junction portion joining the intermediate channel and the space where the fan 40 is arranged.

[0025] For example, in the embodiment illustrated in [Fig.2], the longitudinal axis P along which the handle 31 extends and therefore a part of the intermediate channel is inclined forward in the direction of the treatment face, relative to the axis of rotation X. The portable housing 3 can be configured so that the longitudinal axis P makes a non-zero angle with an axis orthogonal to the lower surface.

[0026] Preferably, the longitudinal axis P forms an angle of between 10° and 15°, typically 12°, with the axis of rotation X. The value of the angle is measured in the positive direction, i.e. trigonometric or counterclockwise, from the axis of rotation X towards the longitudinal axis P. The inclination of the handle 31 relative to the base 4 improves the ergonomics of the device 1 and meets aesthetic requirements.

[0027] Preferably, the flat lower surface, on which the garment steamer 1 is intended to rest, extends in a plane orthogonal to the axis of rotation X of the motor 4L. In other words, the axis of rotation X is orthogonal to the flat lower surface. This helps to improve the balance of the appliance and therefore its ease of use. It also helps to limit the risk of the appliance falling when it is in its resting position.

[0028] With reference to [Fig. 2], the steaming head 2 has a slender shape extending transversely to the handle 31 along axis M. Preferably, the axis of The steaming head M forms an angle between 65° and 90° with respect to the longitudinal axis P of the handle 31. Thus, the front end of the steaming head 2, presenting the treatment plate 20, belongs to a plane in front of the base 4. This allows the base 4 not to interfere with the application of the treatment plate 20 on the textile piece to be steamed.

[0029] Air suction circuit

[0030] Preferably, the steaming head comprises 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 plate 20. This makes it possible to increase the maximum air suction flow rate. 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.

[0031] Preferably, the portable housing 3 may include an upper wall around the steam generation system with an open front end. A superior air circulation channel is thus formed between the air intake port 24 and the upper wall of the portable housing 3, at the periphery of the steam generation system.

[0032] Preferably, the garment steamer comprises a modular unit including a nozzle 26, the steam generation system, and the treatment plate 20. The modular unit is intended to be at least partially inserted into the upper wall of the portable case 3, typically attached at an open front end. The nozzle 26 is configured to form the treatment surface and to support the treatment plate 20 and the steam generation system.

[0033] Preferably, the steaming head 2 includes a sealing gasket 27 disposed between the upper wall of the portable housing and the modular unit, for example, arranged behind the treatment plate, 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. Thus, all the air drawn in through the air intake orifice 24 circulates in the air intake circuit around the steam generation system.

[0034] The air intake circuit extends into the handle 31 of the garment steamer 1. Typically, the handle 31 includes a hollow volume defining the intermediate channel in fluid communication with the upper air circulation channel. The intermediate channel allows air to circulate from the upper portion of the portable unit to the lower portion in which the fan 40 is located.

[0035] Alternatively or additionally, the intermediate air circulation channel can be formed by an added duct 34 inside the handle 31, as illustrated in [Fig. 3]. The direction of airflow in the intermediate air circulation channel, when the fan 40 is rotating, is shown by bold arrows. Typically, the duct is connected to the upper air circulation channel at its upper end. Preferably, the duct includes a sealing gasket 35 disposed at its upper end to prevent air from escaping the air circulation channel at the upper end of the added duct 34. The airflow from the air intake orifice 24 in the upper air circulation channel thus passes through the intermediate air circulation channel without escaping from the steamer 1.This limits pressure loss and improves suction efficiency, thus enhancing the quality of the steaming.

[0036] Preferably, the air intake circuit further includes a junction channel 32 extending from the fan 40 to the handle 31 along an intermediate axis Q, the intermediate axis Q being inclined towards the rear of the steaming head 2 relative to the axis of rotation X.

[0037] Preferably, the intermediate channel extends over the majority of the length of the handle 31, typically over more than 60% of the length of the handle 31. The intermediate channel forms a bend at the junction between the intermediate channel and the junction channel 32. The air circulating in the air suction circuit is therefore diverted at the handle 31 at the bend, then before entering the suction circuit of the base 4 where the fan 40 is located.

[0038] The presence of the bends increases the distance traveled by the vapor-laden air in the air intake circuit upstream of the motor 41, and helps to dry the air before it arrives in the base 4, condensation being able to take place at this level.

[0039] The angular deviation between the longitudinal axis P and the intermediate axis Q is preferably between 20° and 40°. Typically, the angle formed between the intermediate axis Q and the axis of rotation X can be equal to the angle formed between the axis of rotation X and the longitudinal axis P.

[0040] The deviation of the air intake circuit can create a dead zone in which the airflow velocity is almost zero. The dead zone can be located in the extension of the intermediate channel, at the base 4. Preferably, the air intake circuit includes a storage zone 33 disposed in an extension of the intermediate channel, between the junction channel 32 and the portable housing 3. The storage zone is preferably in the dead zone, upstream of the base 4 and the motor 4L

[0041] The presence of the storage zone 33 advantageously allows for the retention of any solid particles, particularly textiles, that may have been drawn into the circuit, or condensate present in the air intake circuit, by promoting the capture of condensate in this zone, the latter being denser than dry air and being carried by its inertia into the storage zone 33. The storage zone 33 may include, for example, baffles or protruding walls in the air intake circuit allowing for the trapping of particles and / or condensate.

[0042] Preferably, the portable unit 3 includes an opening arranged opposite the storage area 33, the opening being closed by a removable cover. For example, the cover forms a drawer allowing the removal of any condensation, textile particles, or lint retained in the storage area. This prevents these particles from obstructing the air intake circuit and, in particular, from blocking the rotation of the motor 41 or the fan 40 around the axis of rotation X. Indeed, obstruction of the intake circuit could lead to excessive power consumption of the motor 41 and its premature wear, or even overheating and serious malfunction of the device 1.

[0043] Preferably, the base 4 comprises a hollow volume defining a lower air circulation channel in fluid communication with the intermediate channel. In the embodiment where the intermediate channel is formed by the added conduit 34 integral with the base 4, the lower air channel can be formed as an extension of the added conduit 34. The optional connecting channel 32 can also be included within the added conduit 34. The fan 40 and the motor 41 are typically arranged within the hollow volume so as to allow circulation of the air drawn in through the air intake port 24.

[0044] The steaming device 1 includes at least one air exhaust port in fluid communication with the air suction circuit, allowing the air sucked in by the air suction port 24 to be evacuated outside the device 1, after circulation in the device 1. The at least one air exhaust port is typically connected to the lower air circulation channel.

[0045] Preferably, the lower air circulation channel comprises a lower end closed by a cover 8, through which passes at least one air exhaust orifice. For example, the lower end is located at the level of the lower surface of the base 4. The presence of a separate cover 8 advantageously allows for cleaning of the lower air circulation channel, for example, to remove any solid particles or lint that may have been drawn into the device 1 and not retained in the storage area 33. This prevents premature obstruction of the lower air circulation channel, which could prevent the rotation of the motor 41 about its axis 42.

[0046] Preferably, the air intake circuit comprises, at the base 4, a central air circulation channel extending along the axis of rotation X and a peripheral air circulation channel concentric with the central air circulation channel. In other words, the lower air circulation channel is divided into two separate, concentric channels. Typically, the central air circulation channel has a smaller diameter than the peripheral air circulation channel. Conversely, the cross-sectional area of ​​the central air circulation channel may be larger than that of the peripheral air circulation channel.

[0047] The motor 41 is arranged in the central air circulation channel. The peripheral air circulation channel is in fluid communication with the air exhaust port.

[0048] The fan 40 is configured to drive an airflow from the air intake port 24 to the air exhaust port, through the peripheral air circulation channel.

[0049] Typically, in the embodiment shown, the fan 40 is located at the inlet of the lower air circulation channel, at a lower end of the intermediate air circulation channel formed by the handle 31. The fan 40 is located upstream of the motor 41, in the direction of airflow within the air intake circuit. The fan 40 comprises a plurality of blades distributed radially around the axis of rotation 42 on a lower wall 44 covering the inlet of the central air circulation channel in which the motor 4L is disposed. The diameter of the lower wall 44 is greater than the diameter of the central air circulation channel, but less than the diameter of the peripheral air circulation channel, so that the lower wall 44 prevents the airflow from the intermediate channel from flowing into the central air circulation channel, directing it towards the inlet of the peripheral air circulation channel..

[0050] Preferably, the garment steamer further comprises a protective element 44 centered on the axis of rotation X so as to cover the central air circulation channel, the protective element 44 being configured to direct an airflow from the intermediate channel to the peripheral air circulation channel. For example, the protective element 44 is a cone formed by the lower wall of the fan 40 which covers the central air circulation channel. Alternatively, the protective element 44 may be an element attached to the shaft 42, separate from the fan 40 and driven by the shaft 42, or alternatively, not integral with the shaft 42 and fixed in the base 4.

[0051] Preferably, the majority of the air from at least one air intake port 24 flows from the intermediate channel to the peripheral air circulation channel, for example via the junction channel 32. The circulation channel The lower central air intake allows for a separate airflow, in order to ensure, in particular, the cooling of engine 41.

[0052] Preferably, the base 4 comprises at least one cooling air inlet and at least one cooling air outlet connected to the central air circulation channel. Advantageously, the steamer 1 further comprises a cooling fan 43 arranged in the base 4 and configured to be driven in rotation by the motor 41 around the shaft 42, i.e., in rotation around the axis of rotation X. The cooling fan is configured to draw an airflow into the central air circulation channel from at least one cooling air inlet to at least one cooling air outlet.

[0053] Typically, at least one cooling air inlet port may be disposed on a side wall extending transversely with respect to the lower surface of the base 4. The air drawn in through the cooling air inlet port when the cooling propeller 43 is rotating is expelled out of the steamer 1 through the cooling air outlet port, the port opening into the central air circulation channel.

[0054] Preferably, at least one cooling air outlet can be arranged on the lower surface of the portable housing 3. In the embodiment where the base 4 includes a lower end formed by a cover 8, the cover 8 can be traversed by the cooling air outlet. The base 4 can include a plurality of cooling air outlets, for example arranged concentrically around the axis of rotation X, in direct extension of the central air circulation channel.

[0055] Preferably, the cooling fan 43 is arranged between the motor 41 and the lower surface of the garment steamer 1. In other words, the cooling fan 43 is arranged downstream of the motor 41 in the direction of the cooling airflow. Thus, the cooling fan 43 partially obstructs the central airflow channel, so as to prevent liquid from passing from the cooling air outlet to the motor 4L. This makes it possible to deflect liquid spray towards the motor 41 from outside the appliance 1, or to prevent liquid from entering the air intake circuit where the motor 41 is located, particularly if the appliance 1 is placed in a resting position on a wet surface S.

[0056] Steam generation system

[0057] Preferably, the treatment face includes a plurality of steam distribution ports 22, typically distributed over the surface of the treatment plate 20. The steam distribution ports 22 may be in the form of holes or slots.

[0058] Generally, the steam generation system may include a vaporization chamber 21, in steam communication with the outside at the level of the treatment surface via at least one 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 1 can be more compact and lighter.

[0059] 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 heating element 23 may be an electric heating element.

[0060] Preferably, the heating element 23 of the steam generation system is arranged close to the treatment plate 20. This allows the treatment plate 20 to be heated in order to obtain more efficient wrinkle removal when the treatment plate 20 is positioned opposite a piece of textile, without reducing the compactness of the device 1 and without increasing its mass.

[0061] 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 further increases the compactness of the garment steamer 1.

[0062] 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 heated efficiently in order to reach the appropriate temperature inside for vaporizing a liquid injected into the vaporization chamber 21, while simultaneously heating the treatment plate 20.

[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 garment steamer 1 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] Typically, the liquid is injected into the vaporization chamber delimited by the vaporization chamber 21 by means of a pump 25. The pump 25 is arranged to circulate the liquid contained in the reservoir 5 towards the vaporization chamber 21. The pump 25 is preferably disposed near the vaporization chamber 21, in the steaming head 2, for example in a central area of ​​the upper portion of the portable housing 3, between the steam generation system and the reservoir 5.

[0068] Preferably, the steam generation system includes electrical safety and thermal control elements. For example, the steam control system may include a thermostat configured to cut off the power supply to the heating element 23 if the temperature exceeds a setpoint temperature.

[0069] Power supply and control of the device

[0070] 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 domestic electrical network. The power cord 6 operates the components of the steam generation system and the air suction circuit, and heats the treatment plate 20 if necessary.

[0071] Preferably, the power cord 6 can be fixed to the base 4. The power cord 6 can be detachable. 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 or held in the hand, at a height greater than 1.5 meters from the ground. The device The steamer 1 has the advantage of being usable with one hand, and does not require a rigid support, as is the case for classic irons.

[0072] The portable unit 3 preferably includes control means configured to control the steam emission, air intake and heating of the heating element 23. The control means 7 are preferably arranged on the gripping portion, in particular at the handle 31, so that they can be operated by the user with the hand used to carry the garment steamer 1.

[0073] The garment steamer 1 may include, for example, a power button 74. The power button 74 allows the garment steamer 1 to be switched on and off. It may be arranged on a wall of the handheld unit 3 forming an upper surface of the base 4, opposite the lower surface, as illustrated in [Fig. 1]. Alternatively, it may be arranged on a side wall of the handheld unit 3, preferably at the handle 31.

[0074] The garment steamer 1 may include, for example, a steam trigger 72. The steam trigger 72 is configured to allow for targeted steam distribution from at least one steam distribution orifice 22. For example, pressing the steam 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 steam trigger 72 is held down by the user. Pressing the vaporization trigger 72 can also activate the motor 41, thus rotating the fan 40 so that a flow of air is drawn in through the air intake orifice 24.

[0075] 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.

[0076] The garment steamer 1 may include, for example, a suction control button 73. The suction control button 73 allows the user to select an operating mode for the garment steamer 1. Typically, the suction control button 73 can rotate the motor 41 so as to modulate the rotational speed of the fan 40 and / or the cooling impeller around the shaft 42. 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, especially fragile fabrics and upholstery fabrics.

[0077] Assembly of the device

[0078] Preferably, the portable unit 3 comprises a one-piece casing, preferably made of plastic. For example, the portable unit 3 may be made of polypropylene or polycarbonate. Thus, the outer surface of the garment steamer 1 is a single piece. This increases the device's resistance to impacts, for example in the event of a fall, and therefore its lifespan.

[0079] Typically, the functional elements of the base 4 are inserted into the portable housing 3 through the lower end of the lower air circulation channel, and the functional elements of the steaming head 2 are assembled onto the portable housing 3 via the nozzle 26. The reservoir 5 can then be mounted on a receiving wall of the rear face of the steaming head 2, in fluid connection with the steam generation system.

[0080] 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. Advantageously, the garment steamer 1 has its center of gravity located in the handle 31, regardless of the fill level of the reservoir 5. Preferably, the mass of the steaming head 2 and the mass of the base 4 are each at least 40% of the total mass of the garment steamer 1, typically less than or equal to 1.4 kg. The garment steamer 1 is thus easy to handle and ergonomic in that the masses of the steaming head 2 and the base 4 are substantially equivalent.

[0081] Use of the garment steamer

[0082] The operation of the garment steamer 1 in the illustrated embodiment 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.

[0083] The heating element 23 of the steam generation system is then supplied with electrical current so as to reach its operating temperature. The treatment plate 20 is also heated, preferably by the common heating element 23.

[0084] 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 7, 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.

[0085] 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 improves the wrinkle removal.

[0086] Simultaneously, the control means, in particular the suction control button 73, can be provided to activate air suction in combination with the steam distribution. Typically, the pressure of the steam trigger 72 drives the motor 4L. Consequently, the fan 40 is driven to rotate around the shaft 42, so that air is drawn in through the air suction port 24. The suction allows the textile to be pressed against the treatment plate 20. The steam emission combined with the suction thus further improves the quality of the wrinkle removal. Moreover, the air suction also promotes the drying of the portion of the textile 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 has been treated.

[0087] Advantageously, the suction control button 73 can be used to change the rotation speed of the motor 41, and thus adapt the flow of air sucked up to the textile piece to be steamed.

[0088] 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.

[0089] 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 plate 20 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.

[0090] 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.
