Description

Technical Field

[0001] The invention relates to a clothing steam ironing machine, which comprises a steam ironing machine head and a detachable docking unit for docking the steam ironing machine head.

[0002] The present invention can be used in the field of clothing care. Background Art

[0003] Garment steamers are known for ironing or steaming garments to remove wrinkles using the heat and moisture from the steam.

[0004] One type of garment steamer is a so-called vertical garment steamer, which comprises a base housing a water reservoir and a steam generating unit. A steamer head (also called ironing device) is connected to the base by a flexible hose through which steam is delivered to the steamer head. A steam plate (also called soleplate) is provided on the steamer head for defining one or more steam vents through which steam is discharged onto the fabric being treated.

[0005] During treatment by a garment steamer, a garment may be hung on a hanger, wherein a user positions the steamer head over the garment to remove wrinkles.

[0006] Vertical garment steamers often include garment support features and / or accessories, such as an ironing board or pad, to help the user achieve better and faster wrinkle removal.The ironing board is typically mounted on a rod assembly.

[0007] In particular, such a vertical garment steam ironing machine may include a tiltable ironing board. The tilting of the ironing board enables the garment to be oriented at different angles when being treated with steam ironing. Since for users who are used to ironing garments (especially long trousers and long-sleeved formal shirts), the user usually desires a horizontal orientation.

[0008] When the user is not in the process of activating steam treatment of laundry, the user usually wishes to rest the steam ironing machine head on the docking unit, in other words, on the supporting means at the side of the rod assembly or at the side of the ironing board.

[0009] Positioning such a docking unit so that the steam ironing head can be easily placed on and picked up from the docking unit can be challenging, especially when the docking unit is to be conveniently used with the ironing board tilted in different angular orientations, such as horizontal and vertical orientations.

[0010] WO 2014 / 102671 A2 discloses a device for guiding a lace cord of a garment care appliance, the device depending downwardly from the appliance during use of the appliance. The device includes a guide tube having a passage therethrough to slidably accommodate a lace cord of the garment care appliance; and an attachment portion for attaching the guide tube to a support so that the guide tube is positioned close to or below the height at which the appliance is being used. The lower portion of the lace cord passing through the guide tube and depending below it allows the upper portion of the lace cord extending between the appliance and the guide tube to remain substantially straight or taut during movement of the appliance toward and away from the device.

[0011] CN205603917U discloses a clothing treatment system, comprising a steam ironing machine head, a steam generator, a steam hose connecting the steam generator and the steam ironing machine head, and a component for docking the steam ironing machine head. Summary of the invention

[0012] It is an object of the present invention to address one or more of the above challenges.

[0013] The invention is defined by the independent claims. The dependent claims define preferred embodiments.

[0014] For this purpose, the clothing steam ironing machine of the present invention comprises:

[0015] base,

[0016] Steam ironing machine head,

[0017] a hose cord for connecting the base to the steam ironing machine head,

[0018] a rod assembly, the rod assembly comprising at least one rod,

[0019] a docking unit for docking the steam ironing machine head during a period of inactive steam treatment, and

[0020] A support arm having a first end and a second end, the first end being used to support the docking unit, and the second end being detachably connected to the rod assembly via a rod assembly coupling device, when the support arm is being attached to or detached from the rod assembly coupling device, the rod assembly coupling device allows horizontal translation relative movement between the support arm and the rod assembly.

[0021] The support arm has a dimension, such as a length dimension, extending from a first end to a second end.

[0022] The rod assembly coupling device may be viewed as defining a specific axis along which the rod assembly coupling device guides horizontal translational relative movement during attachment or detachment of the support arm to or from the rod assembly coupling device.

[0023] In such embodiments, a dimension of the support arm, such as a length dimension, is aligned, for example, along the particular axis during horizontal translational relative movement of the support arm as it is being attached to or detached from the rod assembly coupling.

[0024] Alternatively or additionally, the rod assembly coupling arrangement may include a snap fit mechanism configured to secure the support arm in response to reaching a defined point during horizontal translational relative movement between the support arm and the rod assembly.

[0025] The support arm being detachably connected to the rod assembly may have various advantages. For example, this enables a more compact packaging of the garment steamer, which in turn facilitates transportation and shipment. Alternatively or additionally, the ability to detach the support arm from the rod assembly may enable the docking unit to be installed at other locations on the garment care device. The latter may help to conveniently position the docking unit for the user.

[0026] Horizontal translational relative movement to connect or detach the support arm to or from the pole assembly is considered to be more user friendly than, for example, moving the support arm vertically (eg, up and down) to connect or detach the support arm to or from the pole assembly.

[0027] Since the arrangement of the docking unit enables the user to pick up the steam ironing machine head along a picking direction that is angled with the horizontal plane along which the support arm is translated to be detached from the rod assembly, the risk of the support arm accidentally separating from the rod assembly when the user picks up the steam ironing machine head can be reduced.

[0028] The horizontal translation relative movement may be, for example, a horizontal sliding relative movement.

[0029] In some embodiments, the rod assembly coupling device includes a first coupling mechanism. The first coupling mechanism includes a first cavity disposed on the rod assembly, the first cavity forming a hollow volume adapted to receive the second end of the support arm.

[0030] As the hollow volume of the cavity accommodates the second end of the support arm, the term "cavity" as used herein may alternatively be referred to as a "sheath."

[0031] In some embodiments, the second end of the support arm has an outer surface, and the first cavity is defined by a first wall having a first inner surface. In such embodiments, preferably, the outer surface has substantially the same cross-sectional shape as the first inner surface.

[0032] In other words, the first cavity and the second end are shaped such that the second end can be received in and engaged with the first inner surface of the first cavity.

[0033] Thus, the term "substantially the same" means that the respective cross-sectional shapes of the inner and outer surfaces are sufficiently similar to enable the second end to be received in and engaged with the first inner surface of the first cavity.

[0034] The term "substantially the same" accordingly encompasses the situation where one or both of the inner and outer surfaces include surface features, such as protrusions and / or recesses, as long as these surface features do not prevent the second end from being received in and engaging with the first inner surface of the first cavity.

[0035] In view of this, preferably, the first inner surface of the first wall includes a plurality of first linear protruding ribs.

[0036] The plurality of first linear protruding ribs can help engage and guide the second end into the first cavity while limiting the contact area between the outer surface of the second end and the first inner surface of the first cavity. Such limitation can help minimize friction when the support arm is connected and disconnected from the rod assembly. The protruding ribs can also help better control manufacturing tolerances compared to when the protruding ribs are not included.

[0037] Preferably, the plurality of first linear protruding ribs extend parallel to an axis along which the support arm is translatorily moved relative to and attached to the rod assembly, respectively.

[0038] Alternatively or additionally, opposing portions of the first inner surface may be provided with protruding ribs.

[0039] This can help to minimize the wobble of the support arm when inserted into the first cavity, thereby providing the user with stability and quality assurance of the support arm.

[0040] In some embodiments, the cross-sectional shape of the outer surface and the cross-sectional shape of the first inner surface are both substantially rectangular.

[0041] This generally rectangular shape may help to avoid undesired rotation of the support arm within the first cavity. However, other polygonal cross-sectional shapes, such as square, hexagon, heptagon, octagon, etc., may also be considered for this purpose.

[0042] In at least some embodiments, the support arm includes a flexible tongue with a protruding catch at the end of the tongue, and the first wall includes a first slot. The protruding catch can cooperate with the first slot to lock the support arm in the first cavity.

[0043] The protruding catch and the first slot form a snap-fit ​​mechanism for locking / retaining the support arm in the first cavity. Such a snap-fit ​​mechanism can provide a user-friendly way of connecting and detaching the support arm and the rod assembly from each other.

[0044] Preferably, the flexible tongue and the protruding catch are arranged on the top surface of the support arm.

[0045] This enables a user to clearly see when the support arm and rod assembly are connected and disconnected from each other.

[0046] In some embodiments, the rod assembly coupling device includes a second coupling mechanism. The second coupling mechanism includes a second cavity, which is arranged on the rod assembly and is used to accommodate the second end of the support arm. In such embodiments, the second cavity forms a hollow volume suitable for accommodating the second end of the support arm. Preferably, the second cavity is arranged at 180 degrees relative to the first cavity.

[0047] Therefore, the support arm can be connected to the opposite side of the rod assembly.In this way, both right-handed and left-handed users can comfortably use the garment steam ironing machine.

[0048] In some embodiments, the first cavity is disposed on a first side of the rod assembly and the second cavity is disposed on a second side of the rod assembly opposite the first side, wherein the first cavity and the second cavity open outwardly in opposite directions relative to and away from each other.

[0049] Preferably, the second cavity is defined by a second wall having a second inner surface. In such embodiments, the outer surface of the second end of the support arm has a cross-sectional shape substantially the same as the second inner surface, for example, the cross-sectional shapes of the outer surface and the second inner surface are both polygonal, for example, generally rectangular, as described above with respect to the first cavity.

[0050] Preferably, similar to what is described above with respect to the first cavity, the second inner surface of the second wall defining the second cavity comprises a plurality of second linear protruding ribs.

[0051] In at least some embodiments, the second wall includes a second slot, and a protruding catch disposed on the flexible tongue of the support arm can cooperate with the second slot to lock the support arm in the second cavity.

[0052] The advantages of this locking are the same as those described above with respect to the first cavity.

[0053] Preferably, the structure of the second cavity is the same as that of the first cavity.

[0054] This allows the support arm to be easily attached to the first cavity or the second cavity arranged on either side of the rod assembly because the second end of the support arm is inserted / removed from each of the first cavity and the second cavity using the same connection / detachment scheme.

[0055] In some embodiments, the docking unit is detachably mounted on the first end of the support arm by a coupling that allows the docking unit to be detached and reattached in two angular orientations that are 180 degrees from each other.

[0056] This enables the docking unit to be rotated 180 degrees when the support arm is changed from the left side to the right side of the pole assembly and vice versa, thereby enabling the docking unit to always face the direction most convenient for correct docking by the user of the steam ironing machine head.

[0057] Preferably, the docking unit comprises a support plate for supporting the steam ironing machine head from below.

[0058] For example, a steam plate of the steam ironing machine head defining at least one steam vent may rest on the support plate.

[0059] Preferably, the support plate is inclined at an angle ranging from 30 degrees to 70 degrees relative to the horizontal plane.

[0060] This allows a convenient orientation of the steam ironing head when docking or undocking the steam ironing head with the docking unit.

[0061] Preferably, the support plate comprises side support members extending from a peripheral portion of the support plate to laterally support the steam ironer head.

[0062] This allows the steam ironing machine head to be docked securely and stably in the docking unit.

[0063] In some embodiments, the garment steam ironing machine further comprises an ironing board mounted on the rod assembly. The ironing board comprises a board coupling device, the board coupling device allowing translational relative movement between the support arm and the ironing board when the support arm is attached to or detached from the board coupling device.

[0064] In some embodiments, the board coupling arrangement comprises a snap-fit ​​mechanism configured to secure the support arm in response to reaching a defined point during the translational relative movement between the support arm and the ironing board.

[0065] The board coupling device comprises a board cavity which is open on the periphery of the ironing board. The board cavity forms a hollow volume which is suitable for accommodating the second end of the support arm.

[0066] Preferably, the ironing board extends longitudinally between a first end and a second end, and the board cavity is open at the first end and / or the second end.

[0067] Preferably, the first end tapers towards a more pointed portion of the ironing board, the more pointed portion being opposite the wider end of the second end of the ironing board.

[0068] Preferably, the plate cavity is defined by a wall having an inner surface, the inner surface of the wall defining the plate cavity having a cross-sectional shape substantially the same as the outer surface of the second end of the support arm, such as a polygonal cross-sectional shape, such as a generally rectangular shape, as described above with respect to the first cavity and the second cavity.

[0069] Preferably, the inner surface of the wall defining the plate cavity comprises a plurality of linear projecting ribs, also as described above in relation to the first and second cavities.

[0070] In at least some embodiments, a wall defining the plate cavity is provided with a slot, and the protruding catch described above can cooperate with the slot to lock the support arm in the plate cavity.

[0071] Therefore, the snap-fit ​​mechanism design for removably connecting the support arm to the ironing board can be the same as the snap-fit ​​design for removably connecting the support arm to the rod assembly. This can provide a consistent engagement method at the rod assembly and ironing board locations of the garment steamer. This can further improve the user-friendliness of the garment steamer.

[0089] Figure 1 and Figure 1A A garment care device 100 according to one example is depicted. The garment care device 100 comprises a base 102 and a steam iron head 104. A hose cord 106 connects the base 102 to the steam iron head 104.

[0090] At least one steam nozzle is arranged in the steam ironing machine head 104 (particularly the steam plate of the steam ironing machine head 104), and the steam nozzle is used to release steam to the garments to be treated.

[0091] Preferably, the base 102 includes a water tank (not visible in the figure). The water tank stores water for generating steam. To this end, the garment care device 100 also includes a steam generator (also not visible in the figure), and the water stored in the water tank is supplied to the steam generator.

[0092] In some embodiments, a steam generator is included in the base 102 , and steam generated by the steam generator is supplied to the steam iron head 104 via a hose cord 106 .

[0093] In such embodiments, preferably, the steam ironing head 104 comprises a steam heater (not visible in the figure) arranged to reheat the steam received from the steam generator before the steam leaves the steam ironing head 104 via the at least one steam vent. The steam heater may help to minimize the risk of water droplets splashing onto the treated garments.

[0094] The garment care device 100 comprises a rod assembly 108. Preferably, the rod assembly 108 supports an ironing board 140. To this end, the rod assembly 108 comprises at least one rod. In other words, the rod assembly can be regarded as a support assembly, the purpose of which is to support the ironing surface against which the treated garment can be placed.

[0095] therefore, Figure 1 and Figure 1A The illustrated garment care device 100 may be considered a vertical garment steamer.

[0096] The rod assembly 108 may be made of any suitable material, such as a metal or metal alloy and / or an engineering thermoplastic.

[0097] Preferably, the ironing board 140 can be Figure 1 The vertical orientation shown and Figure 1A The horizontal orientations shown are inclined between. For example, the vertical orientation can be used for steaming hanging garments, while the horizontal orientation can be used for ironing.

[0098] The garment care device 100 comprises a docking unit 110 for docking the steam ironing head 104. The steam ironing head 104 may be docked in the docking unit 110, in other words supported by the docking unit 110, when the steam ironing head 104 is not held by the user, in other words during an inactive steam treatment period.

[0099] It should be noted that the docking unit 110 and the ironing board 140 may be made of any suitable mechanically strong material, such as an engineering thermoplastic material.

[0100] See also Figure 2 and Figure 6Preferably, the docking unit 110 includes a support plate 111A arranged to support the steam ironer head 104 from below, and a side support member 111B extending from a peripheral portion of the support plate 111A to support the steam ironer head 104 laterally.

[0101] Preferably, the support plate 111A is arranged so that the steam ironing head 104 is supported by the docking unit 110 at a certain angle relative to the horizontal plane. This can help the user to easily pick up the steam ironing head 104 and easily put the steam ironing head 104 back to the docking unit 110.

[0102] Preferably, the support plate 111A is inclined at an angle ranging from 30 degrees to 70 degrees relative to a horizontal plane.

[0103] The side support members 111B may help retain the steam iron head 104 on the docking unit 110 despite the support plate 111A being angled relative to the horizontal.

[0104] Preferably, the support plate 111A comprises a surface of a heat insulating material on which the steam plate of the steam ironing head 104 can rest.

[0105] The garment care device 100 further includes a support arm 112 for supporting the docking unit 110. Figure 1 In the illustrated configuration, the docking unit 110 is connected to the pole assembly 108 via a support arm 112 .

[0106] See also Figure 2 , the support arm 112 includes a first end 114. The docking unit 110 is coupled to the support arm 112 at the first end 114.

[0107] In some embodiments, the docking unit 110 is detachably mounted on the first end 114 of the support arm 112 by a coupling that allows the docking unit 110 to be detached and reattached in two angular directions that are 180 degrees from each other.

[0108] Thus, the docking unit 110 may be oriented to always face the direction most convenient for proper docking of the steam iron head 104 by a user, regardless of whether the support arm 112 is attached to the cavity on the right or left side of the wand assembly 108 .

[0109] For example, Figure 5 The steam ironing machine head 104 is depicted in a first orientation in which the body of the steam ironing machine head extends substantially perpendicular to the support arm 112 (the support arm 112 is received within the first cavity 118A), and Figure 5AThe steam iron head 104 is depicted in a second orientation (with the support arm 112 received within the second cavity 118B) after being rotated 180 degrees from the first orientation.

[0110] The removable coupling of the docking unit 110 at the first end 114 to the support arm 112 may be achieved in any suitable manner.

[0111] For example, see Figure 2 and Figure 4 , a protrusion 115A protruding from the first end 114 of the support arm 112 is releasably received in and engaged with a recess provided on a mounting portion 115B of the docking unit 110. In this non-limiting example, the mounting portion 115B extends from the underside of the support plate 111A. The mounting portion 115B has cylindrical symmetry, so that the coupling between the mounting portion 115B and the protrusion 115A can still be achieved after it is rotated 180 degrees.

[0112] Figure 4A depicts an enlarged view of the support arm 112 and the mounting portion 115B of the docking unit 110 according to the present invention, and Figure 4B depicts a side view of a support arm and a docking unit according to the invention,

[0113] Figure 4C An enlarged cross-sectional view of the coupling between the support arm and the mounting portion 115B of the docking unit 110 is depicted in accordance with the present invention.

[0114] The docking unit 110 is removably mounted to the support arm 112, for example, via a "pin and hole" mechanism. When the user actuates the button 117 (the button 117 is spring-loaded by the spring 121), the pin 119 (moving with the button 117) is retracted from the hole 120 formed in the mounting portion 115B, and thus, the mounting portion 115B of the docking unit 110 can be removed from the protrusion 115A of the support arm 112. When the user releases the button, the force applied by the spring causes the pin 119 to extend into the hole 120 and thus lock the docking unit in place on the support arm 112.

[0115] See also Figure 1 and Figure 2 , the second end 116 of the support arm 112 is removably connected to the rod assembly 108 .

[0116] The support arm 112 being detachably connected to the rod assembly 108 can have various advantages. For example, this can enable the removal of the docking unit 110, making the garment steam ironing machine 100 easier to store after use. Alternatively or additionally, the ability of the support arm 112 to be detached from the rod assembly 108 can enable the docking unit 110 to be installed at other locations on the garment care device 100, as will be described in more detail below. The latter can help to conveniently position the docking unit 110 for the user, for example, depending on the orientation of the ironing board 140 (e.g., horizontal or vertical orientation).

[0117] Second end 116 is removably connected to rod assembly 108 via a rod assembly coupling that allows horizontal translational relative movement between support arm 112 and rod assembly 108 when support arm 112 is attached to or detached from the rod assembly coupling.

[0118] Such horizontal translational relative movement is believed to be more user-friendly than, for example, moving the support arm 112 vertically (eg, up and down) to connect or detach the support arm 112 from the pole assembly 108 .

[0119] like Figure 1 , Figure 4 and Figure 5 As best shown in the figures, the support arm 112 has a dimension, such as a length dimension, extending from a first end 114 to a second end 116, wherein the rod assembly coupling device defines a specific axis HA along which horizontal translational relative movement is required to attach the support arm 112 to the rod assembly coupling device and remove the support arm 112 from the rod assembly coupling device.

[0120] In such embodiments, a dimension (eg, a length dimension) of the support arm 112 is aligned along a particular axis HA during horizontal translational relative movement to attach and detach the support arm 112 from the rod assembly coupling.

[0121] Since the arrangement of the docking unit 110 enables the user to pick up the steam ironing head 104 in a direction PD that is angled with the horizontal plane along which the support arm 112 is translated to be detached from the rod assembly 108, the risk of the support arm 112 accidentally being separated from the rod assembly 108 when the user picks up the steam ironing head 104 is reduced. In other words, the steam ironing head picking direction PD is not parallel to the direction of the horizontal translational relative movement along which the support arm is translated to be detached from the rod assembly.

[0122] When the garment steam ironing machine 100 is oriented for use, the axis HA along which the horizontal relative movement (i.e., horizontal translation) occurs is at Figure 1Regardless of whether the garment steam ironing machine 100 is oriented to be on the ironing board 140 as shown in FIG. Figure 1 Whether used in the vertical orientation as shown, or in the case where the ironing board is not in a vertical orientation (eg horizontal or tilted at a certain angle), in at least some embodiments, the axis HA extends transversely (eg perpendicular to) the longitudinal direction LD of the ironing surface.

[0123] The axis HA is in the direction of horizontal translational relative movement. The pick-up direction PD is at an angle to the axis HA, the rod assembly coupling arrangement allowing horizontal translational relative movement along the axis HA. The pick-up direction PD is not parallel to HA, thereby avoiding accidental removal of the support arm during picking up of the steam ironing machine head.

[0124] In some embodiments, and as Figure 3 and Figure 5 As best shown in , the rod assembly coupling device includes a first coupling mechanism. The first coupling mechanism includes a first cavity 118A disposed on / at the rod assembly 108, wherein the first cavity 118A forms a hollow volume adapted to accommodate the second end 116 of the support arm 112.

[0125] See also Figure 2 , the second end 116 of the support arm 112 has an outer surface 120. Figure 3 As shown, the first cavity 118A is defined by a first wall 122A having a first inner surface 124A. In such embodiments, preferably, the outer surface 120 has substantially the same cross-sectional shape as the first inner surface 124A.

[0126] In other words, the first cavity 118A and the second end 116 are shaped such that the second end 116 can be received in and engaged with the first inner surface 124A.

[0127] Thus, the term “substantially identical” means that the respective cross-sectional shapes of the first inner surface 124A and the outer surface 120 are sufficiently similar such that the second end 116 can be received within and engaged with the first inner surface 124A of the first cavity 118A.

[0128] The term “substantially identical” accordingly encompasses the situation where one or both of the first inner surface 124A and the outer surface 120 include surface features, such as protrusions and / or recesses, so long as these surface features do not prevent the second end 116 from being received in and engaged with the first inner surface 124A of the first cavity 118A.

[0129] In view of this, and as described Figure 3 A magnified view of Figure 3AAs best shown in FIG. 1 , the first interior surface 124A of the first wall 122A defining the first cavity 118A preferably includes a first plurality of linear protruding ribs 126A.

[0130] These first plurality of linear protruding ribs 126A can help engage and guide the second end 116 into the first cavity 118A while limiting the contact area between the outer surface 120 of the second end 116 and the first inner surface 124A of the first cavity 118A. This limitation can help minimize friction when connecting and disconnecting the support arm 112 to the rod assembly 108. These first plurality of linear protruding ribs 126A can also help better control manufacturing tolerances compared to when the protruding ribs 126A are not included.

[0131] Preferably, the first plurality of linear protruding ribs 126A each extend parallel to the axis HA.

[0132] Alternatively or additionally, protruding ribs 126A may be provided on opposing portions of the first inner surface 124A of the first cavity 118A.

[0133] This can help to minimize wobble of the support arm 112 when the second end 116 is inserted into the first cavity 118A. Thus, stability and secure connection of the support arm 112 are provided to the user.

[0134] In at least some embodiments, the cross-sectional shape of the outer surface 120 and the cross-sectional shape of the first inner surface 124A of the first wall 122A defining the first cavity 118A are both substantially rectangular.

[0135] This generally rectangular shape can help prevent undesired rotation of the support arm 112 within the first cavity 118A. However, other polygonal cross-sectional shapes, such as square, hexagon, heptagon, octagon, etc., are also contemplated for use for this purpose.

[0136] In at least some embodiments, the support arm 112 includes a flexible tongue 130 having a protruding catch 132 at the end of the tongue 130. The first wall 122A includes a first slot 134A,

[0137] The protruding catch can cooperate with the first slot to lock the support arm in the first cavity. Preferably, the flexible tongue 130 and the protruding catch 132 are arranged on the top surface of the support arm 112.

[0138] The protruding catch and the first slot form a snap-fit ​​mechanism for locking / retaining the support arm in the first cavity. Figures 2 to 5 An example of this situation is best illustrated.

[0139] When the support arm 112 is translated along the axis HA to be received in the first cavity 118A, the protruding catch 132 initially contacts the first wall 122A (whose first inner surface 124A defines the first cavity 118A), causing the tongue 130 to bend and allow the second end 116 to be received in the first cavity 118A. When subsequently advanced along the axis HA, the protruding catch 132 is aligned with the first groove 134A, and at this time, the elasticity of the tongue 130 causes the protruding catch 132 to be positioned in the first groove 134A, thereby locking the support arm 112 in the first cavity 118A.

[0140] like Figure 8 As shown, the button 135 is arranged between the first end 114 and the second end 116. The button 135 is arranged on the tongue 130, away from the protruding catch 132. The button 135, the tongue 130 and the protruding catch 132 are arranged on the top surface of the support arm 112 so that the button is clearly visible to the user when the docking unit 110 is connected to the rod assembly 108 via the support arm 112. This greatly improves the user-friendliness when the support arm 112 is detached from the rod assembly 108.

[0141] When the user wishes to remove the support arm 112 from the rod assembly 108, the user may depress the button 135, for example with a finger, to bend the tongue 130 and bring the protruding catch 132 out of the first slot 134A, thereby extracting the support arm 112 from the first cavity 118A along the axis HA.

[0142] This can help the user intuitively know how to release the snap fit mechanism.

[0143] In some embodiments, and see Figure 5 , the rod assembly coupling device includes a second coupling mechanism. The second coupling mechanism includes a second cavity 118B, which is arranged on the rod assembly 108 and is used to accommodate the second end 116 of the support arm 112. In such embodiments, the second cavity 118B forms a hollow volume suitable for accommodating the second end 116 of the support arm 112.

[0144] Preferably, the second cavity 118B is arranged 180 degrees relative to the first cavity 118A. Therefore, the support arm 112 can be connected to the opposite side of the rod assembly 108. In this way, both right-handed and left-handed users can use the garment steamer 100 comfortably.

[0145] In some embodiments, Figure 5As shown, the first cavity 118A is arranged on the first side S1 of the rod assembly 108, and the second cavity 118B is arranged on the second side S2 of the rod assembly 108 opposite to the first side S1, wherein the first cavity 118A and the second cavity 118B open outward in opposite directions relative to each other.

[0146] Preferably, the second cavity 118B is defined by a second wall 122B having a second inner surface 124B. In such embodiments, the outer surface 120 of the second end 116 of the support arm 112 has substantially the same cross-sectional shape as the second inner surface 124B, such as both being polygonal cross-sectional shapes, such as generally rectangular, as described above with respect to the first cavity 118A.

[0147] Preferably, the second inner surface includes a plurality of second linear protruding ribs, also as described above with respect to the first cavity 118A.

[0148] In at least some embodiments, the second wall 122B includes a second slot 134B, and the protruding catch 132 can cooperate with the second slot to lock the support arm in the second cavity.

[0149] The protruding catch 132 and the second slot 134B form a snap-fit ​​mechanism for locking / retaining the support arm in the second cavity, as similarly described above with respect to the first cavity 118A.

[0150] In some embodiments, the structure of the second cavity 118B is the same as that of the first cavity 118A.

[0151] This allows the support arm 112 to be easily attached to the first cavity 118A or the second cavity 118B arranged on either side S1, S2 of the rod assembly because the second end 116 of the support arm is inserted into / removed from each of the first cavity 118A and the second cavity 118B using the same connection / detachment scheme.

[0152] In some embodiments, and see Figures 6 to 9 , the ironing board 140 comprises a board coupling arrangement which allows a translational relative movement between the support arm and the ironing board.

[0153] The panel coupling device defines another specific axis along which a translational relative movement needs to take place, in other words guided by the panel coupling device, during attachment and detachment of the support arm 112 to and from the panel coupling device.

[0154] In such embodiments, during the translational relative movement of attaching and detaching the support arm 112 to and from the panel coupling device, a dimension (eg, a length dimension) of the support arm 112 is aligned along the other particular axis.

[0155] Preferably, the translational relative movement is parallel to the flat surface of the ironing board on which the garments are arranged during treatment. The plate coupling device comprises a plate cavity 118C open on the periphery of the ironing board. The plate cavity forms a hollow volume suitable for accommodating the second end 116 of the support arm 112.

[0156] Plate cavity 118C is defined by wall 122C having inner surface 124C. Inner surface 124C has substantially the same cross-sectional shape as outer surface 120 of second end 116, such as a polygonal cross-sectional shape, such as a generally rectangular shape, as described above with respect to first cavity 118A and second cavity 118B.

[0157] like Fig. 9 As best shown in FIG. 1 , the inner surface 124C preferably includes a plurality of linear protruding ribs 126C, as similarly described above with respect to the first cavity 118A and the second cavity 118B.

[0158] In at least some embodiments, a groove 134C is arranged in the wall 122C defining the plate cavity 118C, and the protruding snap 132 can cooperate with the groove 134C to lock the support arm 112 in the plate cavity 118C. Therefore, the snap-fit ​​mechanism design for detachably connecting the support arm 112 to the ironing board 140 can be the same as the snap-fit ​​design for detachably connecting the support arm 112 to the rod assembly 108.

[0159] This may provide a consistent method of engagement at the locations of the rod assembly 108 and the ironing plate 140 of the garment steamer 100. This may further improve the user-friendliness of the garment steamer 100.

[0160] In some embodiments, the ironing board 140 extends longitudinally between a first end 142 and a second end 144 , wherein the board cavity 118C is open at the first end and / or the second end.

[0161] Preferably, the first end 142 tapers toward a more pointed portion 146 of the ironing board 140 , which may correspond to the tip of the ironing board.

[0162] The pointed end 146 is opposite a wider end 148 of the second end 144 of the ironing board 140 , which may correspond to a shoulder of the ironing board.

[0163] In the various figures, the plate cavity 118C is open at the wider end 148 .

[0164] The embodiments described above are merely exemplary and are not intended to limit the process of the present invention. Although the present invention is described in detail in conjunction with the preferred embodiments, it should be understood by those skilled in the art that the process may be modified or replaced by equivalents without departing from the scope of protection of the claims of the present invention.
