FIELD OF THE INVENTION
[0001] The invention relates to a garment care device, and in particular controlling steam
delivery from the garment care device.
[0002] The invention may be used in the field of garment care.
BACKGROUND OF THE INVENTION
[0003] Steam irons are known which are capable of removing wrinkles from garments in a similar
manner to garment steamers. Garment steamers enable the user to perform vertical steaming
of hanging garments without the use of an ironing board.
[0004] Conventional steam irons or pressurized steam generators include a so-called "steam
lock" feature that allows the product to produce steam continuously, in similar manner
to garment steamers. The steam lock feature is selectable by the user so that they
can switch to and from the continuous steaming mode according to, for example, whether
the device is intended to be used for steaming a hanging garment or for ironing a
garment on an ironing board.
[0005] A disadvantage of such conventional steam irons/pressurized steam generators is that
the steam lock is required to be switched on and off by the user, for example whenever
a garment is adjusted or a steamed garment is changed for a garment which is yet to
be steamed.
[0006] Should the steam lock be left on by the user, for example during adjusting a garment
or changing garments, so that steam flows continuously throughout the entire ironing
session, energy and water risk being wasted, and steam dips may occur in the boiler
of the device.
[0007] DE 20 2006 001242 U1 discloses a garment care system comprising a steam generator having a steam outlet,
at least one garment care handset having a steam inlet arranged for coupling to the
steam outlet, an opening for releasing steam, and a steam control unit arranged for
controlling a valve for controlling the release of steam.
[0008] EP 3 447 187 A1 discloses a garment care device comprising a sensor for generating an output signal
characterizing a movement of said garment care device, and a control unit coupled
to the sensor. The control unit is adapted to identify and compare characteristics
of the output signal to characteristics of a predefined displacement pattern, and
to adjust at least one operating parameter of the garment care device based on the
result of the comparison between characteristics of the output signal and characteristics
of the predefined displacement pattern.
OBJECT AND SUMMARY OF THE INVENTION
[0009] It is an object of the invention to propose a garment care device that avoids or
mitigates the above-mentioned problems.
[0010] The invention is defined by the independent claims. The dependent claims define advantageous
embodiments.
To this end, the garment care device according to the invention comprises:
- a water tank for containing water,
- a steam generator in fluid communication with the water tank for generating steam,
- a soleplate defining an overall flat surface comprising a plurality of steam vents
in fluid communication with the steam generator,
- controlling means for controlling the flow of steam exiting the steam vents, the controlling
means being adapted to take a first state resulting in steam exiting the steam vents,
and a second state resulting in steam not exiting the steam vents,
- a button adapted to be actuated by a user of the garment care device,
- a first sensing unit for detecting if the user is holding or not the garment care
device,
- a processing unit connected to the button and to the first sensing unit, the processing
unit being adapted to set the controlling means in the first state if the following
primary conditions are fulfilled:
- the button has been continuously pressed by the user during at least a first time
duration, and
- after the first time duration, the first sensing unit detects that the user is holding
the garment care device.
[0011] Thus, the user need only actuate the button for the first time duration, and continue
to hold the garment care device thereafter in order for adoption of the first state
and for steam to correspondingly exit the steam vents.
[0012] In this manner, the user is not required to continually actuate, e.g. press, the
button in order to operate the garment care device in a continuous steaming mode.
[0013] Moreover, the primary conditions will not, or no longer, be fulfilled when the user
is not, or ceases, holding of the garment care device, and the steam will accordingly
not exit the steam vents. In this manner, safety, particularly prior to steaming,
is improved. Wastage of steam and energy is also minimised or prevented when the user
is not holding the garment care device, for instance when the user is adjusting a
garment or changing a steamed garment for a garment which is yet to be steamed.
[0014] The controlling means preferably comprise a valve arranged between the steam generator
and the steam vents. Such a valve provides an effective and responsive way of selecting
the first state or the second state.
[0015] Alternatively or additionally, the controlling means comprise a pump arranged between
the water tank and the steam generator. The pump provides an effective and readily
implementable way of selecting the first state or the second state.
[0016] Preferably, the garment care device further comprises a second sensing unit connected
to the processing unit for measuring an angular position of the overall flat surface
compared to a horizontal surface. In this case, the primary conditions also include
the following additional condition:
- after the first time duration, the second sensing unit detects that the angular position
is larger than a given angle threshold.
[0017] Continuous steaming in the first state is likely to be preferred by the user for
steaming a hanging fabric or garment, but such continuous steaming may be inappropriate
when using the garment care device for ironing a garment on the horizontal surface
of an ironing board. These user preferences are accounted for by the primary conditions
including the additional requirement that the second sensing unit detects that the
angular position is larger than the given angle threshold.
[0018] The given angle threshold is at least 20 degrees, preferably in the range of 20°C
to 40°C, e.g. 30°C, compared to the horizontal.
[0019] This range for the given angle threshold reflects that the first state is triggered
by an inclined orientation away from the horizontal, and may also assist to prevent
unintentional triggering of the first state resulting from the soleplate being positioned,
e.g. seated, on an inclined base/cradle.
[0020] Preferably, the additional condition that, after the first time duration, the second
sensing unit detects that the angular position is larger than the given angle threshold
is fulfilled when the angular position is larger than the given angle threshold for
at least a given minimum time duration.
[0021] The given minimum time duration can assist to ensure stability of the angular position
measurement, and can be, for instance, in the range of 100 to 500 milliseconds, such
as 200 milliseconds.
[0022] Preferably, the garment care device comprises a third sensing unit for measuring
movement of the garment care device. In this case, the primary conditions also include
the following additional condition:
- after the first time duration, the third sensing unit detects a movement having a
first value larger than a first movement threshold.
[0023] This may assist to improve the responsiveness of, and thus improve the user's experience
of using, the garment care device. This is because the steam is permitted to exit
the steam vents provided, e.g. as soon as, the user is moving the garment care device.
[0024] Preferably, the processing unit is adapted to set the controlling means in the second
state if the first sensing unit detects that, at a certain time, the user is not holding
the garment care device anymore.
[0025] The term "certain time" is intended to mean in the present context the time at which
the user is not, or no longer, holding the garment care device. Thus, the steaming
provided when the controlling means are in the first state is stopped, or at least
temporarily paused, when the user is no longer holding the garment care device.
[0026] Preferably, the processing unit is adapted to set the controlling means in the first
state again if the following secondary conditions are fulfilled:
- the first sensing unit detects that within a second time duration starting from the
certain time, the user is holding the garment care device again.
[0027] This enables the steaming to be resumed following a temporary pause in the steaming
resulting from the user no longer holding the garment care device.
[0028] The second time duration can be, for example, in the range of 10 to 30 seconds, such
as 15 seconds.
[0029] When the garment care device includes the second sensing unit, the secondary conditions
preferably also include the following condition:
- during the second time duration, the second sensing unit detects that the angular
position of the overall flat surface compared to the horizontal surface is larger
than the given angle threshold.
[0030] Thus, tilting of the soleplate so that the given angle threshold is exceeded can
be conveniently used as one of the secondary conditions which permit resumption of
continuous steaming following the temporary pause.
[0031] Alternatively or additionally, when the garment care device includes the third sensing
unit, the secondary conditions preferably also include the following condition:
during the second time duration, the third sensing unit detects a movement having
a second value larger than a second movement threshold.
[0032] Thus, moving the at least part of the garment care device so that the second movement
threshold is exceeded can be conveniently used as one of the secondary conditions
which permit resumption of continuous steaming following the temporary pause.
[0033] Preferably, the processing unit is adapted to maintain the controlling means in the
first state as long as the third sensing unit detects that the movement of the garment
care device is above a third movement threshold.
[0034] The third movement threshold can be the same as or different from the first and second
movement thresholds. In a non-limiting example, the third movement threshold is lower
than the first movement threshold and/or the second movement threshold. The third
movement threshold can thus account, for example, for relatively small movements associated
with directing steam at one part of a fabric in order to remove a stubborn wrinkle.
[0035] Preferably, the processing unit is adapted to set the controlling means in the second
state as soon as the button is actuated by the user.
[0036] In this manner, steaming is stopped by adoption of the second state as a result of
the user actuating the button while the controlling means are in the first state.
[0037] Preferably, the first time duration is in the range of 1 to 5 seconds, such as 2
seconds. Such a first time duration assists to prevent unintentional adoption of the
first state by the controlling means, whilst minimising inconvenience and discomfort
otherwise caused to the user due to having to actuate, e.g. press, the button for
a relatively prolonged period of time.
[0038] Preferably, the first sensing unit comprises a capacitive sensor configured to detect
when the user is touching the garment care device. Alternative sensor types can also
been considered for the first sensing unit, such as an optical sensor, an ultrasonic
sensor, etc.
According to another aspect there is provided a method of controlling steam generation
in a garment care device comprising:
- water tank for containing water,
- a steam generator in fluid communication with the water tank for generating steam,
- a soleplate defining an overall flat surface comprising a plurality of steam vents
in fluid communication with the steam generator,
- controlling means for controlling the flow of steam exiting the steam vents, the controlling
means being adapted to take a first state resulting in steam exiting the steam vents,
and a second state resulting in steam not exiting the steam vents,
- a button adapted to be actuated by a user of the garment care device,
- a first sensing unit for detecting if the user is holding or not the garment care
device,
the method comprising the step of setting the controlling means in the first state
if the following primary conditions are fulfilled:
- the button has been continuously pressed by the user during at least a first time
duration, and
- after the first time duration, the first sensing unit detects that the user is holding
the garment care device.
[0039] A computer program product is also provided, which computer program product comprises
instructions codes which, when executed by the processing unit of the garment care
device defined above, cause the garment care device to implement the method as defined
above.

to the method and computer program product, for example the control logic used in
such a computer program product, are applicable to the garment care device.
[0041] Detailed explanations and other aspects of the invention will be given below.

DETAILED DESCRIPTION OF THE INVENTION
[0043] Fig.1 depicts a garment care device 100A according to a first example. The garment
care device 100A comprises a water tank 102 for containing water. A steam generator
104 for generating steam is in fluid communication with the water tank 102.
[0044] In the non-limiting example depicted in Fig.1, water is pumped from the water tank
102 to the steam generator 104 by a pump 106. Steam is generated in the steam generator
104 from the water pumped thereto by the pump 106. To this end, the steam generator
104 includes a heating element (not visible), such as a resistive heating element,
arranged to heat the water therein to generate the steam.
[0045] The garment care device 100A further comprises a soleplate 108. The soleplate 108
has, or may be regarded as defining, a surface for treating fabrics.
[0046] As shown in Fig.1, the soleplate 108 delimits a plurality of steam vents 110. The
steam vents 110 are fluidly communicable with the steam generator 104, as will be
explained in more detail herein below. Fluid communication between the steam generator
104 and the steam vents 110 permits the steam generated in the steam generator 104
to be supplied to a fabric (not visible) adjacent, and in some cases contacting, the
soleplate 108.
[0047] The surface of the soleplate 108 is an overall flat surface 109. The term "overall
flat" refers to the surface 109 being planar but including discontinuities, in particular
due to the presence of the steam vents 110.
[0048] The exemplary garment care device 100A depicted in Fig.1 comprises a base 112 and
a hand unit 114. The base 112 comprises the water tank 102, the steam generator 104,
and the pump 106. The hand unit 114 comprises the soleplate 108, as shown.
[0049] A hose cord 116 includes a steam tube (not visible) for carrying steam from the steam
generator 104 to the steam vents 110. The hose cord 116 is preferably flexible in
order to facilitate movement of the hand unit 114 whilst maintaining supply of steam
from the steam generator 104 to the steam vents 110.
[0050] In the non-limiting example shown in Fig.1, steam from the steam generator 104 is
received in a steam chamber 118 included in the hand unit 114. The steam vents 110
are in fluid communication with the steam chamber 118. Thus, the steam in the steam
chamber 118 is carried by the steam vents 110 towards the fabric to be treated.
[0051] The steam vents 110 may, for example, be arranged in such a way as to distribute
the steam to different portions of the fabric.
[0052] Whilst Fig.1 shows a garment care device 100A having six steam vents, this is merely
for the purpose of illustration, and any suitable alternative number of steam vents
110 may be considered, such as two, three, four, five, seven, eight, nine, ten, eleven,
twelve, or more.
[0053] Moreover, the garment care device 100A need not comprise the base 112 and hand unit
114 components shown in Fig.1, and an example of an alternative design will be described
in more detail herein below with reference to Figs.3 and 4.
[0054] More generally, the garment care device 100A comprises controlling means 120 configured
to control the flow of steam exiting the steam vents 110. The controlling means 120
adopt a first state and a second state. In the first state, steam is permitted by
the controlling means 120 to exit the steam vents 110.
[0055] In the second state, steam is not permitted by the controlling means 120 to exit
the steam vents 110. This may, for example, be implemented by the controlling means
120 preventing the fluid communication between the steam generator 104 and the steam
vents 110 in the second state, thereby to prevent the exit of steam from the steam
vents 110.
[0056] The controlling means 120 can, for example, be alternatively termed a "steam controller",
due its function of controlling whether or not steam is permitted to exit the steam
vents 110.
[0057] The controlling means 120 can be implemented in any suitable manner. In the non-limiting
example shown in Fig.1, the controlling means 120 comprise, or are at least partly
defined by, a valve 122 arranged between the steam generator 104 and the steam vents
110.
[0058] The valve 122 can have any suitable design provided that it can be controlled in
response to certain primary conditions being fulfilled, as will be described in more
detail herein below. The valve 122 may, for example, comprise, or be in the form of,
an electro-valve or solenoid valve.
[0059] In the exemplary garment care device 100A depicted in Fig.1, the first state is adopted
by the valve 122 being open to permit steam generated in the steam generator 104 to
pass to and exit the steam vents 110. The second state is adopted by the valve 122
being closed to prevent the steam generated in the steam generator 104 from passing
to and exiting the steam vents 110.
[0060] The controlling means 120, including the valve 122, are included in the base 112
in the example shown in Fig.1. However, this should not be regarded as being limiting,
and at least part of the controlling means 120, e.g. the valve 122, may be positioned
elsewhere in the garment care device 100A, such as in the hand unit 114.
[0061] More generally, the garment care device 100A comprises a button 124. The button 124
is actuatable by a user of the garment care device 100A.
[0062] Any suitable design of button 124 may be considered, such as a push button, slider
button, etc.
[0063] Preferably, the garment care device 100A comprises a handle 126 for grasping by the
user in order to assist the user to move the soleplate 108 relative to the fabric
to be treated. The handle 126 may thus be included in the hand unit 114.
[0064] When the handle 126 is included in the garment care device 100A, the button 124 is
preferably arranged proximal to the handle 126 such that the button 124 is actuatable
while the user is grasping the handle 126, e.g. by the hand and/or the digits thereof
which is or are grasping the handle 126.
[0065] The garment care device 100A comprises, in addition to the button 124, a first sensing
unit 128 configured to detect whether or not the user is holding the garment care
device 100A.
[0066] The first sensing unit 128 may have any suitable design or may be of any suitable
type that is capable of detecting whether or not the user is holding at least part
of the garment care device 100A. For example, the first sensing unit 128 comprises,
or is defined by, a sensor, such as a touch sensor configured to detect holding of
the at least part of the garment care device 100A by the user.
[0067] A capacitive sensor may be a particularly suitable touch sensor for detecting holding
of the garment care device 100A by the user.
[0068] Preferably, the first sensing unit 128 is provided on or proximal to the handle 126,
as shown in Fig.1. Such positioning of the first sensing unit 128 means that holding
of the at least part of the garment care device 100A is detected by the first sensing
unit 128 when the user makes contact with, and preferably grasps, the handle 126.
[0069] In the non-limiting example shown in Fig.1, the first sensing unit 128 is arranged
on the underside of the handle 126 such that the holding is detected when the user's
hand and/or digits reach around to the underside when grasping the handle 126.
[0070] Alternatively, the first sensing unit 128 is arranged such as to detect contact being
made with the upper side of the handle 126. An example of this will be explained herein
below with reference to Fig. 5.
[0071] More generally, the garment care device 100A comprises a processing unit 130 connected
to the button 124 and to the first sensing unit 128.
[0072] The processing unit 130 is configured to set the controlling means 120 to adopt the
first state if the following primary conditions are fulfilled: the button 124 has
been continuously pressed by the user during at least a first time duration, and after
the first time duration, the first sensing unit 128 detects that the user is holding
the garment care device 100A.
[0073] Preferably, the first time duration is in the range of 1 to 5 seconds, such as 2
seconds. Such a first time duration assists to prevent unintentional adoption of the
first state by the controlling means 120, whilst minimising inconvenience and discomfort
otherwise caused to the user due to having to actuate, e.g. press, the button 124
for a relatively prolonged period of time.
[0074] Thus, the user need only actuate the button 124 for the first time duration, and
continue to hold the at least part of the garment care device 100A thereafter in order
for adoption of the first state, and correspondingly for steam to exit the steam vents
110.
[0075] In this manner, the user is not required to continually actuate, e.g. press, the
button 124 in order to operate the garment care device 100A in a continuous steaming
mode.
[0076] Moreover, the primary conditions will not, or no longer, be fulfilled when the user
is not holding the at least part of the garment care device 100A, and the steam will
accordingly not exit the steam vents 110. In this manner, wastage of steam and energy
is minimised or prevented when the user is not holding the at least part of the garment
care device 100A, e.g. when the user is adjusting a garment or changing a steamed
garment for a garment which is yet to be steamed.
[0077] In the case of the exemplary garment care device 100A shown in Fig.1, the processing
unit 130 is configured to control the valve 122, e.g. comprising an electro-valve
or solenoid valve, of the controlling means 120 to open to allow steam to pass from
the steam generator 104 to the steam vents 110 based on the above-described primary
conditions being fulfilled.
[0078] The processing unit 130 is further configured to control the valve 122 of the controlling
means 120 to close in order to prevent steam from passing from the steam generator
104 to the steam vents 110 when at least one of the above-described primary conditions
is not fulfilled.
[0079] Controlling the flow of steam by the processing unit 130 sending control signals
to the valve 122 of the controlling means 120 provides an effective way of toggling
between the first state and the second state. The control over steam exiting the steam
vents 110 may thus be relatively rapidly responsive to the user inputs received via
(at least) the button 124 and the first sensing unit 128.
[0080] The processing unit 130 can be implemented in numerous ways, with software and/or
hardware, to perform the various required functions. A processor is one example of
a processing unit 130 which employs one or more microprocessors that can be programmed
using software (e.g., microcode) to perform the functions. The processing unit 130
may, however, be implemented with or without employing a processor, and also may be
implemented as a combination of dedicated hardware to perform some functions and a
processor, e.g. one or more programmed microprocessors and associated circuitry, to
perform other functions.
[0081] Examples of controller components that may be employed in various embodiments of
the present disclosure include, but are not limited to, conventional microprocessors,
application specific integrated circuits (ASICs), and field-programmable gate arrays
(FPGAs).
[0082] In some examples, the processing unit 130 is associated with one or more storage
media such as volatile and non-volatile computer memory such as RAM, PROM, EPROM,
and EEPROM. The storage media can be encoded with one or more programs that, when
executed on one or more processors and/or controllers, perform the required functions.
Various storage media may be fixed within the processing unit 130 or may be transportable,
such that the one or more programs stored thereon can be loaded into the processing
unit 130.
[0083] In the exemplary garment care device 100A shown in Fig.1, the processing unit 130
is included in the base 112, although other suitable locations for the processing
unit 130, such as in the hand unit 114, can be considered. An example of the latter
will be described in more detail herein below with reference to Figs.3 and 4.
[0084] When the processing unit 130 is included in the base 112, the button 124 and the
first sensing unit 128 can be connected with the processing unit 130 in any suitable
manner, e.g. via wiring (not visible) included in the hose cord 116 .
[0085] Fig.2 depicts a garment care device 100B according to a second example in which the
controlling means 120 comprise a pump 106 arranged between the water tank 102 and
the steam generator 104.
[0086] In the non-limiting example shown in Fig.2, the steam generator 104 is included in
the hand unit 114. In this case, the steam chamber 118 is included in, or may define,
the steam generator 104. The steam vents 110 are in fluid communication with the steam
chamber 118 of the steam generator 104. Fluid communication between the steam generator
104 and the steam vents 110 permits the steam generated in the steam generator 104
to be supplied to a fabric adjacent, and in some cases contacting, the soleplate 108,
as previously described in relation to Fig.1.
[0087] The processing unit 130 is configured to control the pump 106 of the controlling
means 120 to pump water from the water tank 102 to the steam generator 104 in order
to generate steam, which steam is allowed to pass from the steam generator 104 to
and through the steam vents 110 based on the above-described primary conditions being
fulfilled.
[0088] When at least one of the above-described primary conditions is not fulfilled, the
processing unit 130 is configured to control the pump 106 of the controlling means
120 to not pump, or cease pumping, the water from the water tank 102 to the steam
generator 104. In this way, steam production is prevented from taking place, and so
steam does not exit the steam vents 110.
[0089] In other words, steam being permitted to exit the steam vents 110 or otherwise is
based on controlling production of the steam by regulating pumping of water from the
water tank 102 to the steam generator 104. This provides an effective and readily
implementable way of toggling between the first state and the second state.
[0090] In the non-limiting example depicted in Fig.2, the water tank 102, the pump 106 of
the controlling means 120, and the processing unit 130 are included in the base 112,
and the steam generator 104 is included in the hand unit 114.
[0091] In this case, the hose cord 116 correspondingly comprises a water tube (not visible)
for carrying the water from the water tank 102 in the base 112 to the steam generator
104 in the hand unit 114.
[0092] Figs.1 and 2 both depict pressurized steam generator (PSG) architectures. The steam
generator 104, in other words boiler, is included in the base 112 in the device depicted
in Fig.1. Such a boiler 104 is not included in the base 112 in the device shown in
Fig.2. Nevertheless, the water tank 102 is included in the base 112 in both of these
examples. But as briefly mentioned above, these designs should not be regarded as
being limiting.
[0093] Fig.3 depicts a garment care device 100C according to a third example which has some
similarities with the garment care device 100B depicted in Fig.2, in that the controlling
means 120 comprise a pump 106 arranged between the water tank 102 and the steam generator
104.
[0094] In the non-limiting example shown in Fig.3, the various components of the garment
care device 100C are each included in the hand unit 114. Accordingly, the water tank
102, the steam generator 104 which comprises or is defined by the steam chamber 118,
the controlling means 120, in this case comprising or in the form of the pump 106,
and the processing unit 130 are included in the hand unit 114, together with the soleplate
108, the button 124, and the first sensing unit 128.
[0095] The shown in Fig.3 corresponds to a steam iron, sometimes referred to as "DTS". It
may necessitate a smaller water tank 102 due to the water tank 102 being incorporated
in the hand unit 114 rather than in a base, although the garment care device 100C
may nonetheless benefit from portability and have space-saving advantages due to not
requiring such a base. The responsiveness of the steam delivery to the user inputs
received via (at least) the button 124 and the first sensing unit 128 may also be
relatively rapid due to the proximity of the water tank 102 with respect to the steam
generator 104.
[0096] More generally, the processing unit 130 is preferably adapted to set the controlling
means 120 in the second state as soon as the button 124 is actuated by the user, and
it also exits the "continuous steaming" totally.
[0097] In this manner, steaming is stopped by adoption of the second state as a result of
the user actuating the button 124 while the garment care device 100A, 100B, 100C is
in the first state.
[0098] Following adoption of the first state, steaming, in other words continuous steaming,
is started and the user should not actuate the button 124 unless they wish to stop
the steaming. However in this non-limiting example, the user can exit the first state
at any time by (re-)actuating the button 124. For example, such re-actuation can be
implemented by a relatively short actuation of the button 124, e.g. for less than
2 seconds, or alternatively via a relatively long actuation of the button 124, e.g.
for longer than 2 seconds.
[0099] Unintended or accidental actuation of the button 124 is considered to be unlikely
or rare, and is not considered to significantly impact user safety. This is at least
partly because the primary conditions also comprise the requirement that, after the
first time duration during which the button 124 has been continuously pressed by the
user, the first sensing unit 128 detects that the user is holding the garment care
device 100A, 100B, 100C.
[0100] The placement of the button 124, e.g. relative to the handle 126, may also assist
to ensure that the user is less likely to actuate the button 124 unintentionally during
steaming with the controlling means 120 in the first state. Nevertheless, unintentional
or accidental actuation of the button 124 may not give rise to a safety concern when
such unintentional actuation causes the garment care device 100A, 100B, 100C to switch
from the first state in which steam is permitted to exit the steam vents 110 to the
second state resulting in steam not exiting the steam vents 110.
[0101] The processing unit 130 is preferably adapted to set the controlling means 120 in
the second state if the first sensing unit 128 detects that at a certain time, the
user is not holding the garment care device 100A, 100B, 100C, in other words the at
least part of the garment care device 100A, 100B, 100C, anymore. This can be, for
example, an alternative to or in addition to setting the controlling means 120 to
adopt the second state as soon as the button 124 is actuated by the user.
[0102] The term "certain time" is intended to mean in the present context the time at which
the user is not, or no longer, holding the at least part, e.g. the handle 126, of
the garment care device 100A, 100B, 100C.
[0103] Thus, the steaming, e.g. continuous steaming, provided when the controlling means
120 are in the first state is stopped, or at least temporarily paused, when the user
is no longer holding the at least part of the garment care device 100A, 100B, 100C.
[0104] Preferably, the processing unit 130 is adapted to set the controlling means 120 in
the first state again if the following secondary conditions are fulfilled: the first
sensing unit 128 detects that within a second time duration starting from the certain
time, the user is holding the garment care device 100A, 100B, 100C again.
[0105] This means the steaming is resumed following the steaming being paused by the user
no longer holding the at least part of the garment care device 100A, 100B, 100C.
[0106] The second time duration can be, for example, in the range of 10 to 30 seconds, such
as 15 seconds.
[0107] If the user does not hold the garment care device 100A, 100B, 100C again within the
second time duration, the garment care device 100A, 100B, 100C, and in particular
the processing unit 130 thereof, can revert to a first mode in which the primary conditions
must be fulfilled in order for the first state to be adopted.
[0108] In other words, the garment care device 100A, 100B, 100C exits a second/steaming
mode, e.g. a vertical steaming mode which will be described in more detail herein
below with reference to Fig.4, and enters the first mode if the user does not hold
the garment care device 100A, 100B, 100C again within the second time duration. In
this case, the user will have to satisfy the primary conditions again in order for
the first state to be adopted by first actuating the button 124 during at least the
first time duration. This will also be described herein below with reference to Fig.6.
[0109] Fig.4 depicts a garment care device 100D according to a fourth example in which the
garment care device 100D further comprises a second sensing unit 132 connected to
the processing unit 130. It is noted that this is also applicable for embodiments
of Figs. 1 and 2.The second sensing unit 132 is configured to measure an angular position
A1 of the overall flat surface 109 of the soleplate 108 compared to a horizontal surface
HS.
[0110] In other words, the second sensing unit 132 measures the angle A1 of the longitudinal
axis LA of the soleplate 108 relative to the horizontal.
[0111] In this non-limiting example, the primary conditions also include the following additional
condition: after the first time duration, the second sensing unit 132 detects that
the angular position A1 is larger than a given angle threshold A2.
[0112] The garment care device 100D, and in particular the hand unit 114 of the garment
care device 100D, is preferably usable in different orientations.
[0113] For example, a horizontal orientation of the soleplate 108 can be used for ironing
fabrics on a horizontal surface HS, e.g. of a horizontally orientated ironing board.
The orientation of the soleplate 108 may, however, be changed in order to allow the
garment care device 100D to be used for steaming, for instance, fabrics or garments
hanging from a hanger. The latter may mean that the soleplate 108, and in particular
the longitudinal axis LA of the soleplate 108, becomes non-horizontally-orientated,
for example 90° to the horizontal, or more generally at an angle between the horizontal
and the vertical. For example, the orientation detected as vertical is based on an
inclination angle threshold of 30° compared to the horizontal, and any detected angles
below 30° is considered as horizontal, and vice versa as vertical.
[0114] The user may prefer different steaming control according to whether the garment care
device 100D is being used for (e.g. horizontal) ironing or (e.g. vertical) steaming
of a hanging fabric or garment. Continuous steaming in the first state is considered
to be preferred by the user for steaming a hanging fabric or garment. It is for this
reason that the primary conditions in this example include the additional requirement
that the second sensing unit 132 detects that the angular position A1 is larger than
the given angle threshold A2.
[0115] This additional condition is to allow steam release only when soleplate is in vertical
orientation after user has entered the so called vertical steaming mode by the long
press of button.
[0116] It is noted that this is distinct from certain conventional solutions in which, for
safety reasons, continuous steaming is stopped when the soleplate exceeds an equivalent
of the given angle threshold A2. Such safety considerations may not apply in the present
example because of the other primary conditions which are required to be fulfilled
in order for the controlling means 120 to adopt the first state.
[0117] The given angle threshold A2 is at least 20 degrees, preferably in the range of 20°C
to 40°C, e.g. 30°C, compared to the horizontal.
[0118] This range for the given angle threshold A2 reflects that the first state is triggered
by an inclined orientation away from the horizontal, and may also assist to prevent
unintentional triggering of the first state resulting from the soleplate 108 being
positioned, e.g. seated, on an inclined base/cradle.
[0119] The second sensing unit 132 can include any suitable sensor for measuring the angular
position A1, in other words tilt angle, of the soleplate 108. For example, the second
sensing unit 132 comprises an accelerometer, such as a micro electromechanical system
(MEMS) accelerometer.
[0120] Such an accelerometer, e.g. MEMS accelerometer, permits measurement of acceleration
along vertical and horizontal axes to derive the tilt angle A1 of the soleplate 108.
[0121] The angle measurement is preferably a static measurement, in that no comparison is
made with previous measurements.
[0122] Preferably, the additional condition that after the first time duration, the second
sensing unit 132 detects that the angular position A1 is larger than the given angle
threshold A2 is fulfilled when the angular position A1 is larger than the given angle
threshold A2 for at least a given minimum time duration.
[0123] The given minimum time duration can assist to ensure stability of the angular position
A1 measurement. The given minimum time duration is preferably in the range of 100
to 500 ms, such as 200 ms.
[0124] When, for example, the second sensing unit 132 comprises the MEMS accelerometer,
and the given angle threshold A2 is at least 20 degrees, preferably in the range of
20°C to 40°C, preferably 30°C, compared to the horizontal, the given minimum time
duration being in the range of 100 to 500 ms, preferably 200 ms, may ensure stability
of the detected signal. This is because sufficient sampling, e.g. more than 20 samples,
can be held during such a time duration.
[0125] As described above, the processing unit 130 is, in certain examples, adapted to set
the controlling means 120 in the first state again if the secondary condition that
the first sensing unit 128 detects that, within the second time duration, the user
is holding the at least part of the garment care device 100D again. This is so that
continuous steaming can be resumed. When the garment care device 100D includes the
second sensing unit 132, the secondary conditions preferably also include the condition
that during the second time duration, the second sensing unit 132 detects that the
angular position A1 of the overall flat surface 109 of the soleplate 108 compared
to the horizontal surface HS is larger than the given angle threshold A2.
[0126] Thus, tilting of the soleplate 108 sufficiently so that the given angle threshold
A2 is exceeded can be conveniently used as one of the secondary conditions which permit
resumption of continuous steaming via the first state of the controlling means 120
following a temporary pause or interruption.
[0127] At this point it is noted that the design in which the second sensing unit 132 is
included in the garment care device 100D can also be applied to the designs depicted
in Figs.1 and 2 in which a base 112 is included in the garment care device 100A, 100B.
For example, and similarly to the garment care device 100D shown in Fig.4, the second
sensing unit 132 can be included in the hand unit 114 of the garment care device 100A,
100B.
[0128] Similar considerations are applicable to the third sensing unit 134 described herein
below, since the third sensing unit 134 can also be incorporated into either of the
designs depicted in Figs. 1 and 2, for instance by including the third sensing unit
134 in the hand unit 114 of the garment care device 100A, 100B.
[0129] The garment care device 100D preferably comprises such a third sensing unit 134 configured
to measure movement of the garment care device 100D, in other words at least part
of the garment care device 100D. In the non-limiting example shown in Fig.4, the third
sensing unit 134 is included in the hand unit 114.
[0130] Whilst the third sensing unit 134 is included in addition to the second sensing unit
132 in the example depicted in Fig.4, this is not intended to be limiting. In other
examples, the third sensing unit 134 is included as an alternative to the second sensing
unit 132, or the second sensing unit 132 is included as an alternative to the third
sensing unit 134.
[0131] When the third sensing unit 134 is included in the garment care device 100D, the
primary conditions also include the additional condition that after the first time
duration, the third sensing unit 134 detects a movement having a first value larger
than a first movement threshold.
[0132] This may assist to improve the responsiveness of, and thus improve the user's experience
of using, the garment care device 100D by the steam exiting the steam vents 110 provided,
e.g. as soon as, the user is moving the at least part of the garment care device 100D.
[0133] Movement detection by the third sensing unit 134 may be a dynamic measurement in
which each sample is compared to the previous sample, and movement is detected by
determining whether or not the change between the samples is above a certain threshold.
[0134] The third sensing unit 134 can include any suitable motion sensor for sensing movement
of the at least part of the garment care device 100D. For example, the third sensing
unit 134 comprises an accelerometer, such as a micro electromechanical system (MEMS)
accelerometer.
[0135] The accelerometer can be the same as or different from the accelerometer described
above in relation to the second sensing unit 132, in examples in which the garment
care device 100D comprises the second sensing unit 132 and the third sensing unit
134.
[0136] When such an accelerometer is included in the third sensing unit 134, the movement
detected by the third sensing unit 134 is an acceleration, and the additional condition
is that the acceleration detected by the third sensing unit 134 is larger than a first
acceleration threshold; the latter corresponding to the above-mentioned first movement
threshold.
[0137] In a non-limiting example, movement is detected by measuring the acceleration in
any one of three orthogonal axes. A detection algorithm thus checks for acceleration
values along the X-axis, Y-axis, and Z-axis respectively. If acceleration, or change
in acceleration, along any of these axes is greater than the first acceleration threshold,
or first acceleration change threshold, for a sufficient time duration, the acceleration-related
condition is fulfilled.
[0138] For instance, if an acceleration exceeds a first acceleration threshold in the range
of 5 to 20 milli g, preferably 10 milli g, during at least 50 to 500 milliseconds,
preferably 100 milliseconds, the acceleration-related additional condition is fulfilled.
It is noted these milli g values can be converted to S.I. units by noting that 1 milli
g = 0.001 g; and 1 g = 9.81m/s
2.
[0139] The acceleration-related additional condition and the angular orientation-related
additional condition can also be used in combination when the third sensing unit 134
and the second sensing unit 132 respectively are included in the garment care device
100D.
[0140] Thus, the controlling means 120 are controlled by the processing unit 130 to adopt
the first state provided that the angular position A1 is larger than the given angle
threshold A2, e.g. more than 30°, and provided that the movement has a first value
larger than the first movement threshold. Employing movement detection in the primary
conditions in this manner assists to ensure that steaming in the first state is not
triggered when the at least part of the garment care device 100D, e.g. the hand unit
114, is stationary but docked in a base/cradle at an angle which causes the angular
position A1 to exceed the given angle threshold A2. In this respect, docking of the
hand unit 114 can be, for instance, at an angle exceeding 40°, such as 43°.
[0141] As described above, the processing unit 130 can be adapted to set the controlling
means 120 in the first state again if the secondary condition that the first sensing
unit 128 detects that, within the second time duration, the user is holding the at
least part of the garment care device 100D again. This is so that continuous steaming
can be resumed. When the garment care device 100D includes the third sensing unit
134, the secondary conditions preferably also include the condition that, during the
second time duration, the third sensing unit 134 detects a movement having a second
value which is larger than a second movement threshold.
[0142] Thus, moving the at least part of the garment care device 100D sufficiently so that
the second movement threshold is exceeded can be conveniently used as one of the secondary
conditions which permit resumption of continuous steaming via the first state of the
controlling means 120 following a temporary pause or interruption.
[0143] In a non-limiting example, the first movement threshold is the same as the second
movement threshold, such that a first or second movement of sufficient magnitude can
exceed both movement thresholds.
[0144] In other examples, the second movement threshold is greater than the first movement
threshold so that resumption of steaming in the second/steaming mode following a pause
is required to be triggered by a more pronounced movement of the at least part of
the garment care device 100D.
[0145] More generally, the processing unit 130 is preferably adapted to maintain the controlling
means 120 in the first state as long as the third sensing unit 134 detects that the
movement of the garment care device 100D, in other words at least part of the garment
care device 100D, is above a third movement threshold.
[0146] The third movement threshold can, for example, be lower than the first movement threshold
and/or the second movement threshold. This means that steam can continue to be released
by the controlling means 120 being in the first state even when there are only relatively
small movements of the at least part of the garment care device 100D being detected.
This may assist the garment care device 100D to continue to supply steam continuously
when, for example, the user holds the hand unit 114 in one place over a fabric in
order to remove a stubborn wrinkle.
[0147] Fig.5 provides a perspective view of a hand unit 114 of a garment care device 100A,
100B, 100C, 100D. In this non-limiting example, the first sensing unit 128, the second
sensing unit 132, and the third sensing unit 134 are assembled into the handle 126
of the hand unit 114.
[0148] More generally, by locating one or more of the sensing unit(s) 128, 132, 134 in the
handle 126, the risk of damaging such components, for example by heat from the steam
generator 104/steam chamber 118, or as a result of water leaking from the water tank
102, may be reduced.
[0149] A printed circuit board assembly 136 comprising the sensor of the second and third
sensing units 132, 134, e.g. the above-described accelerometer, is mounted in the
handle 126 within a first housing part 138.
[0150] The printed circuit board assembly 136 further comprises electronics included in
the first sensing unit 128. In this example, the first sensing unit 128 comprises
a capacitive sensor. A capacitive flex 140 of the capacitive sensor is built inside
the top cover 137 of the handle 126. The capacitive flex 140 is disposed on top of
a second housing part 142 which, together with the first housing part 138, encloses
the printed circuit board assembly 136. An elastomeric or rubber material 144 is also
included to fill up the air gap which would otherwise be present within the top cover
137 of the handle 126.
[0151] Fig.6 provides a flowchart of a non-limiting exemplary method of controlling steam
generation in a garment care device 100D. Decision box 200 of the control logic depicted
in Fig.6 corresponds to whether or not the button 124 is actuated, e.g. pressed, for
longer than the first time duration D1, e.g. 2 seconds.
[0152] If the answer to decision box 200 is "No", alternative modes can, for example, be
offered to the user in box 202, such as Manual, Auto, Speed. These options can, for
example, be provided, e.g. looped, via a suitable user interface. The user interface
can include an indicator, such as a light emitting diode (LED), which indicates the
alternative mode selected by the user. This is represented in box 204.
[0153] For example, the speed mode is indicated by the LED being continuously illuminated,
the auto mode is indicated by the LED flashing or blinking, and the manual mode is
indicated by the LED not being illuminated. Other suitable ways of representing the
modes of the garment care device 100D can be considered.
[0154] If the answer to decision box 200 is "Yes", this can optionally be indicated via
the user interface in box 206. This provides feedback to the user that they have actuated
the button 124 for more than the first time duration D1. For example, an LED can flash
or blink and/or a buzzer can provide an audible indication, such as a beep.
[0155] Decision box 208 corresponds to whether or not the user is detected to be holding
the garment care device 100D. This makes use of the first sensing unit 128, which
can comprise a touch sensor, e.g. a capacitive touch sensor, as previously described.
[0156] If the answer to decision box 208 is "No", the control logic proceeds to decision
box 210. Decision box 210 corresponds to if the user has been detected as not holding
the garment care device 100D for more than the second time duration D2.
[0157] If the answer to decision box 210 is "Yes", the control logic returns to decision
box 200. This means that the user is required to actuate the button 124 for longer
than the first time duration if the user wishes to go back to the decision box 208.
[0158] If the answer to decision box 210 is "No", the control logic returns to decision
box 208.
[0159] If the answer to decision box 208 is "Yes", the control logic proceeds to decision
box 212. Decision box 212 corresponds to whether or not the angular position A1 of
the overall flat surface 109 of the soleplate 108 exceeds the given angle threshold
A2, e.g. 30°. This makes use of the second sensing unit 132, which may comprise an
accelerometer, as previously described.
[0160] If the answer to decision box 212 is "No", the control logic returns to decision
box 212 via a loop.
[0161] If the answer to decision box 212 is "Yes", the control logic proceeds to decision
box 214. Decision box 214 corresponds to whether or not a movement of at least part
of the garment care device 100D has a first value MV1 which is larger than a first
movement threshold MV1_TH. This makes use of the third sensing unit 134, which may
comprise an accelerometer, e.g. the same accelerometer as included in the second sensing
unit 132, as previously described.
[0162] Alternatively, the decision is whether or not a movement of at least part of the
garment care device 100D has a second value MV2 larger than a second movement threshold
MV2_TH, as previously described in respect of the secondary conditions for resuming
steaming following a temporary pause.
[0163] If the answer to decision box 214 is "No", the control logic returns to decision
box 214 via a loop.
[0164] If the answer to decision box 214 is "Yes", the control logic proceeds to box 216.
Box 216 corresponds to the controlling means 120 adopting the first state such that
steam exits the steam vents 110.
[0165] Decision box 218 corresponds to whether or not the user is detected, via the first
sensing unit 128, to be holding the garment care device 100D while the steam is exiting
the steam vents 110.
[0166] If the answer to decision box 218 is "Yes", the control logic returns to box 216
via a loop, and the steam continues to exit the steam vents 110.
[0167] If the answer to decision box 218 is "No", the control logic proceeds to box 220.
Box 220 corresponds to adoption of the second state by the controlling means 120,
such that the steam no longer exits the steam vents 110. This may, for example, be
a pause in the exiting of steam from the steam vents 110.
[0168] The control logic then proceeds to decision box 208 and the paused steaming is either
resumed via "Yes" answers to decision blocks 208, 212 and 214, or the control logic
returns, via "No" and "Yes" answers to decision blocks 208 and 210 respectively, to
decision block 200. In the latter scenario, the user is once again required to actuate,
e.g. press, the button 124 for more than the first time duration D1 should the user
wish for the controlling means 120 to (re-)adopt the first state such that steam exits
the steam vents 110.
