Field of the invention
[0001] The present invention generally relates to the field of laundry treatment appliances
(hereinafter, concisely, "laundry appliances"), and particularly to laundry appliances
for treating,
e.g. washing, items (such as linen, clothes, garments, shoes, and the like), such as laundry
washing appliances and laundry washing appliances also implementing laundry drying
functions (also referred to as washers/dryers). More particularly, the present invention
relates to a laundry appliance with an improved and user-friendly drawer.
Background of the invention
[0002] A laundry appliance typically comprises a drawer having drawer compartments for containing
one or more treatment agents (such as liquid and powder treatment agents), and a drawer
seat for slidably housing the drawer within it.
[0003] A typical drawer comprises one or more components that can be actuated by the user
(hereinafter, actuatable components). Examples of actuatable components of the drawer
are a detach component for allowing a drawer handle to be detached from a drawer body,
one or more adapter components each one configured to be reversibly inserted into
a respective drawer compartment for adapting it to liquid or powder treatment agents,
an extraction component for reversibly extracting the drawer from the drawer seat,
one or more access components (
e.g., doors) for selectively accessing respective drawer compartment(s), and one or more
plug components for selectively plugging or unplugging emptying holes of respective
drawer compartments.
[0004] With particular reference to the access components, the access components typically
comprises a number of doors each one associated with a respective drawer compartment.
The drawers of currently marketed laundry appliances, especially of high quality laundry
appliances, comprise each one a relatively high number of drawer compartments, and
hence a relatively high number of doors associated threwith.
Summary of invention
[0005] The Applicant has realized that a high number of doors in a drawer, besides being
not very gratifying for the user in terms of aesthetics, may also negatively affect
user experience when the user interacts with it.
[0006] Indeed, the Applicant has ascertained that a drawer having a relatively high number
of doors may be discouraging for the user, in that the user has to remember associations
between the doors and the respective drawer compartments. This could cause risks of
confusion that could be frustrating for the user. Moreover, relatively frequent undesired
actuations of the doors in the attempt to identify a desired drawer compartment may
lead to a premature wear of the doors.
[0007] The Applicant has also ascertained that a relatively high number of doors makes drawer
aesthetics not at all pleasant, rather the resulting drawer aesthetics could instead
give to the user a feeling of low attention to detail: in fact, a relatively high
number of doors typically results in differences in heights among the doors (due to
unavoidable manufacturing tolerances), and in an excessive number of unaesthetic door
contour lines (due to the gaps, between the doors and the rest of the drawer, allowing
actuation of the doors) which could be in contrast with a fine and minimal appearance
of the rest of the drawer. Therefore, user perception of the laundry appliance (and
hence customer loyalty towards the laundry appliance manufacturer) may be negatively
affected.
[0008] In view of the above, it is an object of the present invention to provide a laundry
appliance able to overcome these, as well as other, drawbacks, and particularly it
is an object of the present invention to provide a laundry appliance having a simple,
pleasant and user-friendly drawer.
[0009] One or more aspects of the present invention are set out in the independent claims,

Detailed description of preferred embodiments of the invention
[0037] With reference to the drawings,
Figures 1A and
1B show perspective views of a laundry appliance
100 according to an embodiment of the present invention. According to the exemplary,
not limiting, embodiment herein considered, the laundry appliance
100 is a washing machine. In any case, although in the following description explicit
reference will be made to a washing machine, this should not to be construed as a
limitation; indeed, the present invention applies to other types of laundry appliances
(for example combined washers/dryers,
i.e. washing machines also having laundry drying functions).
[0038] The laundry appliance
100 comprises a (
e.g., parallepiped-shaped) cabinet
105, which preferably accommodates a treatment chamber (
i.e., a laundry washing chamber in the example herein considered of a washing machine)
for performing a laundry treatment cycle on items housed therein (
i.e., a washing cycle on a laundry load in the example herein considered of a washing machine).
[0039] The laundry washing chamber comprises a washing tub (not shown) and, within it, a
(
e.g., rotatable) washing basket or drum (not shown) adapted to contain the laundry load
to be washed. A cabinet front has a loading opening providing access to the drum for
loading/unloading the laundry load, a door
110 (shown in a closed position in
Figures 1A and
1B) being provided for sealably closing the loading opening during the operation of
the laundry appliance
100.
[0040] Although not shown, the laundry appliance
100 also comprises, enclosed in the cabinet
105, electrical/electronic/mechanical/hydraulic components for the operation of the laundry
appliance
100 (such as for example motor, electromechanical valves, pumps and impellers of the
hydraulic apparatus, one or more heating elements for heating water/treatment agents/air).
[0041] The laundry appliance
100 further comprises a drawer
115 for containing one or more laundry treatment agents (or, concisely, treatment agents),
such as liquid and powder treatment agents including, but not limited to, washing
detergents, rinsing detergents, bleaches and softeners. The laundry appliance
100 also comprises a drawer seat
120 for housing the drawer
115, the drawer
115 being advantageously configured to slide into the drawer seat
120, along a longitudinal or sliding direction
X, between an extracted position (shown in
Figure 1A as having a partially extracted position) and a retracted position (shown in
Figure 1B). The drawer seat
120 is preferably provided on a top part of a cabinet front.
[0042] Preferably, the laundry appliance
100 further comprises a user interface
125, the user interface
125 being preferably provided on the top part of the cabinet front, more preferably next
to the drawer seat
120 along a transversal direction
Y orthogonal to the longitudinal direction
X.
[0043] Preferably, although not necessarily, the user interface
125 comprises a display unit, not shown, for visually displaying one or more pieces of
information; the display unit may for example be a light emitting polymer display
(LPD), a liquid crystal display, a thin film transistor-liquid crystal display, or
an organic light-emitting diode display.
[0044] The user interface
125 preferably comprises one or more control elements (
e.g., selection buttons and/or knobs) for allowing the user to select a washing cycle and
to control one or more operating parameters of the selected washing cycle (including,
but not limited to, temperature, laundry load dirt level, spin speed, start time delay,
drawer compartment selection, treatment agent selection). Additionally, as herein
exemplary assumed, or alternatively, the user interface
125 preferably comprises one or more status indicators for indicating to the user a status
of the laundry appliance
100; for example, the status indicators may be configured to indicate the status of one
or more components of the laundry appliances
100 (for example, or one or more drawer components that can be actuated by the user,
as better discussed in the following) and/or a status of the washing cycle (including,
but not limited to, information about a residual time to the end of the ongoing washing
cycle, and/or information about a current phase of the ongoing washing cycle, and/or
selected parameters for the ongoing washing cycle, and/or selected drawer compartment,
and/or selected treatment agent).
[0045] With reference now to
Figure 2A, it shows perspective views of the drawer
115 according to an embodiment of the present invention. For ease of description,
Figure 2A will be discussed jointly with
Figure 2B, which shows a perspective exploded view of the drawer
115, with
Figure 2C, which shows a perspective exploded view of a drawer cover and of a door associated
therewith, and with
Figure 2D, which shows a perspective and partially exploded view from behind of the drawer
115.
[0046] Preferably, the drawer
115 is generally made of a single plastic material, exception made for some parts thereof
which advantageously comprise materials conveniently different from the plastic material
of most of the drawer
115 (as detailed below while discussing embodiments of the present invention).
[0047] As visible in
Figure 2B, the drawer
115 preferably comprises a drawer handle
205 allowing the user to slidably move the drawer
115 between the extracted position and the retracted position when it is fitted into
the drawer seat
120, and a drawer body
210 to which the drawer handle
205 is adapted to be mounted (advantageously, in a removable or reversible way, as better
discussed in the following).
[0048] The drawer
115 preferably comprises two or more (two, in the example at issue) drawer compartments
2201,2202 each one adapted to contain multiple doses of a respective treatment agent for performing
multiple washing cycles, hereinafter referred to as multi-dose compartments: therefore,
the exemplary considered laundry appliance
100 is configured to implement an auto-dosing functionality in which, at each washing
cycle (and when the auto-dosing functionality is enabled), a predetermined amount
of treatment agent is automatically taken (
e.g., by means of a pump, preferably a peristaltic pump, not shown) from one or both of
the multi-dose compartments
2201,2202. Just as an example, the multi-dose compartment
2201 may be arranged to contain multiple doses of a liquid washing detergent, whereas
the multi-dose compartment
2202 may be arranged to contain a multiple doses of a liquid softener. Preferably, the
drawer
115 also comprises, associated with the multi-dose compartments
2201,2202, two or more access openings; more preferably each access opening allows accessing
a respective one of the multi-dose compartments
2201,2202 for treatment agent loading.
[0049] Additionally, as herein exemplary assumed, the drawer body
210 preferably comprises one or more (two, in the example at issue) drawer compartments
2151,2152 each one adapted to contain a single dose of a respective treatment agent for performing
a single washing cycle, hereinafter referred to as mono-dose compartments
2151,2152; just as an example, the mono-dose compartment
2151 may be arranged to contain a single dose of a powder or liquid washing detergent,
whereas the mono-dose compartment
2152 may be arranged to contain a single dose of a powder or liquid or pearl softener.
Preferably, although not necessarily, the mono-dose compartments
2151,2152 are formed side by side along the transversal direction
Y; more preferably, the mono-dose compartments
2151,2152 are formed in an area of the drawer body
210 that, when the drawer handle
205 is mounted on the drawer body
210, is proximal to the drawer handle
205 (hereinafter referred to as front area of the drawer body
210). Preferably, herein assumed, each mono-dose compartment
2151,2152 extends in depth (
i.e., along a vertical direction
Z orthogonal to the longitudinal
X and transversal
Y directions) from a top of the drawer body
210 that identifies a respective access mouth for allowing treatment agent loading from
above.
[0050] Preferably, as visible in
Figure 2B, the drawer
115 also comprises one or more adapter components each one configured to be inserted
into or removed from a respective mono-dose compartment
2151,2152 for adapting it to, respectively, liquid or powder treatment agents. In the example
at issue, a single adapter component is provided, namely an adapter component (globally
denoted by the number reference
2151,AD) configured to be reversibly housed into the mono-dose compartment
2151
[0051] In the exemplary illustrated embodiment, the adapter component
2151,AD comprises a container (for example, a cup-shaped container)
C1,AD adapted to be reversibly housed into the mono-dose compartment
2151 when a liquid treatment agent is intended to be loaded. The adapter component
2151,AD advantageously comprises a siphon pipe
SP1,AD (preferably, formed in a single piece with the container
C1,AD) to induce a siphon phenomenon, and a siphon cap
SC1,AD coupled (or adapted to be coupled) to the siphon pipe
SP1,AD: when the liquid washing detergent in the container
C1,AD exceeds a limit level, a siphon phenomenon occurs, whereby the liquid washing agent
to be supplied during the washing cycle is previously discharged through the siphon
pipe
SP1,AD into the drawer seat
120 and then into the washing tub.
[0052] Preferably, as visible in
Figure 2B, the container
C1,AD fits the access mouth of the mono-dose compartment
2151, exception made for an inclined edge
IE1,AD of the container
C1,AD. When the container
C1,AD is housed in the mono-dose compartment
2151, a gap is defined between the mono-dose compartment
2151 (
e.g., a corner of the substantially square-like shape of its access mouth) and the inclined
edge
IE1,AD of the container
C1,AD, whereby the inclined edge
IE1,AD of the container
C1,AD defines a grip portion adapted to be grasped for easily actuating (
e.g., inserting into and removing from the mono-dose compartment
2151) the container
C1,AD (or, more generally, the adapter component
2151,AD). According to a preferred embodiment of the present invention, at least part of
the inclined edge
IE1,AD (
e.g., the top edge part that, when the drawer
115 is fitted into the drawer seat
120, is visible by as user looking at the drawer
115) is made of a material different from the plastic material of most of the drawer
115. The material of the inclined edge
IE1,AD (or of part thereof) may for example comprise a synthetic rubber or a thermoplastic
material,
e.g. formed by overmolding or co-molding techniques.
[0053] In the example illustrated embodiment, a container (for example, a cup-shaped container)
C2,AD having a siphon pipe (not visible, and preferably formed in a single piece with the
container
C2,AD) to induce a siphon phenomenon is associated with the mono-dose compartment
2152. Although not shown, the container
C2,AD may also comprise a grip portion (
e.g., similar to the grip portion of the container
C1,AD) to allow insertion and removal thereof into and from, respectively, the mono-dose
compartment
2152.
[0054] Preferably, although not necessarily, the multi-dose compartments
2201,2202 are formed side by side along the transversal direction
Y. More preferably, the multi-dose compartments
2201,2202 are formed in an area of the drawer body
210 (hereinafter referred to as rear area of the drawer body
210) that, along the sliding direction
X, is rearward with respect to the front area of the drawer body
210 (
i.e., the area of the drawer body
210 where the mono-dose compartments
2151,2152 are provided). Even more preferably, as visible in the figures, the front and rear
areas of the drawer body
210 are properly different in size, and particularly the rear area of the drawer body
210 is larger than the front area of the drawer body
210 (
e.g., the rear area of the drawer body
210 being for example from 2 to 4 times larger than the front area of the drawer body
210); when, as herein exemplary considered, same extensions in depth of the mono-dose
2151,2152 and multi-dose
2201,2202 compartments are assumed, having the rear area of the drawer body
210 larger than the front area of the drawer body
210 translates into correspondingly different capacities of the mono-dose
2151,2152 and multi-dose
2201,2202 compartments (with the multi-dose compartments
2201,2202 that are sized to store larger amounts of treatment agent as compared to the mono-dose
compartments
2151,2152).
[0055] Forming the multi-dose compartments
2201,2202 behind the mono-dose compartments
2151,2152 is advantageous in that a low or relatively low extraction of the drawer
115 is required for allowing the user to load the treatment agents in the mono-dose compartments
2151,2152 (on the contrary, forming the mono-dose compartments
2151,2152 behind the multi-dose compartments
2201,2202 would dramatically impair the mechanical stability of the drawer
115, for example when extracting the drawer
115 to load the treatment agent in the mono-dose compartments
2151,2152 and a certain amount of treatment agent is still stored in one or more of the multi-dose
compartments
2201,2202).
[0056] As visible in
Figure 2B, one or more emptying holes each one associated with a respective multi-dose compartment
2201,2202 are preferably provided in the drawer body
210 for emptying the respective multi-dose compartment
2201,2202, i.e. for discharging it from the treatment agent contained therein (
e.g. for maintenance or cleaning of the drawer
115). In the example at issue, two emptying holes
210H1,210H2 are provided in the drawer body
210, the emptying hole
210H1 being associated with the multi-dose compartment
2201 and the emptying hole
210H2 being associated with the multi-dose compartment
2202 - however, in further embodiments of the present invention (not shown), emptying
holes associated with the mono-dose compartments
2151,2152 may be provided additionally or alternatively to the emptying holes
210H1,210H2
[0057] In the exemplary considered embodiment, each emptying hole
210H1,210H2 comprises a circular opening located on a respective side of the drawer body
210 (preferably, a bottom part thereof),
i.e. the side of the drawer body
210 that delimits the respective multi-dose compartment
2201,2202 along the transversal direction
Y. Each emptying hole
210H1,210H2 is advantageously closable or pluggable by means of a selectively removable plug
component (or, concisely, plug)
210P1,210P2 (the plugs
210P1,210P2 being both visible in
Figure 2B detached or removed from the respective emptying holes
210H1,210H2, whereas a plug covering the respective emptying hole, such as the plug
210P1 covering the emptying hole
210H1, is visible in
Figure 2A). Advantageously, each emptying hole
210H1,210H2 is located, along the sliding direction
X, in an advanced position of the drawer body
210 (
i.e., towards the drawer handle
205); therefore, when the drawer
115 is sufficiently extracted or pulled out, the plugs
210P1,210P2 become accessible and can be removed to free the emptying holes
210H1,210H2. Therefore, upon sufficient extraction or pulling out of the drawer
115 and removal of the plug(s)
210P1,210P2, the treatment agent(s) in the multi-dose compartment(s)
2201,2202 is caused to flow outside through the respective emptying hole(s)
210H1,210H2,
e.g. for being collected in a proper gathering container placed under the drawer
115 (the flowing of the treatment agent outside the multi-dose compartments
2201,2202 through the emptying holes
210H1,210H2 being for example promoted by a proper slanting or other draining shape of a bottom
wall of the drawer body
210).
[0058] By extraction or pulling out of the drawer
115 it is herein intended the actuation along the sliding direction
X of the drawer
115 within the drawer seat
120 (
i.e., with the drawer
115 that is attached to or connected to or coupled to or fitted into the drawer seat
120); attachment or connection or coupling or fitting of the drawer
115 is preferably releasable (so as to detach or disconnect or decouple or unfit the
drawer
115 from the drawer seat
120) by means of an extraction component (only a part thereof being visible in
Figure 2D and globally denoted by the number reference
210E).
[0059] For the purposes of the present disclosure, the extraction component
210E is preferably coupled or coupleable to the drawer seat
120 (advantageously, on a front part thereof that, in use, faces the drawer handle
205). More preferably, the extraction component
210E comprises a releasable locking element
210E,LOC for locking the extraction component
210E in a slot 120S of the drawer seat
120 (thus firmly securing the extraction component
210E to the drawer seat
120 during actuation of the extraction component
210E).
[0060] Preferably, the extraction component
210E further comprises an extraction actuator
210E,ACT (visible in
Figure 2D) actuatable by the user in order to decouple the drawer
115 from the drawer seat
120. Preferably, the extraction component
210E comprises a catch portion
210E,CAT adapted to engage a blocking portion (not shown) of the drawer body
210; more preferably, the extraction actuator
210E,ACT is mechanically coupled to the catch portion
210E,CAT for operating the extraction component
210E between a first condition in which the catch portion
210E,CAT engages the blocking portion thereby preventing extraction of the drawer
115 from the drawer seat
120 and a second condition in which the catch portion
210E,CAT disengages the blocking portion thereby allowing extraction of the drawer
115 from the drawer seat
120 (with the extraction component
210E that, when the drawer
115 is extracted from the drawer seat
120, is firmly coupled to the drawer seat
120 by means of the locking element
210E,LOC being fitted in the slot
120S). A more detailed description of the extraction component
210E (and of embodiments thereof) can be found in
EP2876197, which is herein incorporated by reference.
[0061] Preferably, the drawer
115 also comprises a drawer cover
225 for covering the drawer body
210. More preferably, the drawer cover
225 is configured to cover the rear area of the drawer body
210, thus leaving uncovered the front area of the drawer body
210, and hence the mono-dose compartments
2151,2152; the mono-dose compartments
2151,2152 can therefore be directly accessed from above (
i.e., through the respective access mouths) for loading the treatment agents therein. Even
more preferably, the drawer cover
225 comprises the above mentioned access openings associated with the multi-dose compartment
2201,2202 for loading the treatment agent; in the example at issue in which the drawer body
210 comprises two multi-dose compartments
2201,2202, two access openings
2301,2302 are provided in the drawer cover
225.
[0062] However, embodiments of the present invention may be provided in which the drawer
115 comprises no drawer cover
225; in this case, similarly to the mono-dose compartments
2151,2152, the top of the drawer body
210 at each multi-dose compartment
2201,2202 identifies a respective access mouth of that multi-dose compartment
2201,2202 for allowing treatment agent loading from above (in the following, any considerations
about the access openings
2301,2302 and interactions thereof with other drawer parts or components are intended to equivalently
apply to the access mouths associated with the multi-dose compartment
2201,2202 when no drawer cover
225 is provided). Alternatively, the drawer cover
225 may be configured to cover also the front area of the drawer body
210; in this case, the drawer cover
225 may comprise access openings associated with the mono-dose compartment
2151,2152 for loading the treatment agent; in the example at issue in which the drawer body
210 comprises two mono-dose compartments
2151,2152, two access openings may be provided in the drawer cover
225.
[0063] One or more of the access openings
2301,2302 (preferably, each one of the access openings
2301,2302) comprises, at an inner part thereof, a level indicator for indicating a level of
treatment agent that is recommended to be loaded in the respective multi-dose compartment
2201,2202. In the considered embodiment, only one level indicator is assumed, for example the
level indicator associated with the access opening
2301 (visible in
Figures 2B and
2C and denoted by the number reference
2301L). Each level indicator, such as the level indicator
2301L, may for example be in the form of a horizontally projecting fin preferably formed
at a proper inner wall of the respective access opening (
e.g., in a single piece with it), more preferably at a corner of the substantially square-like
shape of the respective access opening.
[0064] Preferably, although not necessarily, the access openings
2301,2302 are formed in the drawer cover
225 side by side along the transversal direction
Y.
[0065] The access openings
2301,2302 are advantageously formed in an area
225A of the drawer cover
225 that, when the drawer cover
225 is mounted on the drawer body
210, is proximal to the front area of the drawer body
210 (
i.e., the area of the drawer body
210 where the mono-dose compartments
2151,2152 are provided), or substantially proximal thereto (as detailed here below): therefore,
a low or relatively low extraction of the drawer
115 is required for allowing the user to load the treatment agents in the multi-dose-compartments
2201,2202 (an excessive extraction of the drawer
115 would instead impair the mechanical stability of the drawer
115, essentially due to its elongated shape and/or to its relatively heavy weight, especially
when treatment agents are contained therein).
[0066] Advantageously, the area
225A of the drawer cover
225, and hence the access openings
2301,2302, are formed at such a distance (along the longitudinal direction
X) from the access mouths of the mono-dose compartments
2151,2152 (or the access openings associated with the mono-dose compartments
2151,2152, when provided) that a free region
240 is defined in the drawer cover
225 preferably adapted to contain one or more pieces of information for the user. Exemplary
pieces of information that may be contained in the free region
240 are information about correct dosages of the treatment agents according to treatments
agents and/or water chemical parameters, and/or general indications or instructions
about a correct operation or setting of the auto-dosing functionality.
[0067] According to the exemplary, not limiting, embodiment of the present invention, the
area
225A of the drawer cover
225 in which the access openings
2301,2302 are formed is a recessed area
225A, the recessed area
225A being recessed (along the vertical direction
Z) with respect to a top profile of the drawer cover
225.
[0068] As better visible in
Figure 2C, the recessed area
225A preferably comprises a rim region
225AR that substantially (or at least partially) surrounds the access openings
2301,2302. The rim region
225AR preferably comprises a front portion
225AR,F (in use, the front portion
225AR,F being for example proximal to the drawer handle
205 or, when provided, to the free region
240), and side portions
225AR,S1,225AR,S2. More preferably, each side portion
225AR,S1,225AR,S2 of the rim region
225AR, or at least a relevant part thereof, opens to a respective side edge portion
225S1,225S2 of the drawer cover
225 (in order to house a respective grip portion, as discussed below); in other words,
the top profile of the drawer cover
225, and particularly the side edge portion thereof, stops in correspondence of each side
portion
225AR,S1,225AR,S2 of the rim region
225AR.
[0069] As exemplary illustrated in
Figures 2A and
2B, additionally to the recessed area
225A of the drawer cover
225, a recessed area is advantageously provided in the drawer body
210; preferably, as illustrated, the recessed area of the drawer body
210 comprises two opposite recessed side portions
210AR,S1,210AR,S2 that open to respective side edge portions
210S1,210S2 of the drawer body
210 (in order to house the respective grip portion, as discussed below); in other words,
the recessed side portions
210AR,S1,210AR,S2 are recessed, along the vertical direction
Z, with respect to a top profile of the side edge portions
210S1,210S2 of the drawer body
210 (or, otherwise stated, the top profile of the side edge portions
210S1,210S2 of the drawer body
210 stops in correspondence of each recessed portion side
210AR,S1,210AR,S2)
.
[0070] Advantageously, as visible in
Figure 2A, upon mounting of the drawer cover
225 onto the drawer body
210, the side edge portions
225S1,225S2 of the drawer cover
225 are, along the transversal direction
Y, adjacent (e.g., inwardly adjacent) and preferably in contact to the side edge portions
210S1,210S2 of the drawer body
210. Even more advantageously, upon mounting of the drawer cover
225 onto the drawer body
210, the top profiles of the side edge portions
225S1,225S2 of the drawer cover
225 and of the side edge portions
210S1,210S2 of the drawer body
210 are flush to each other along the vertical direction
Y, and the side portions
225AR,S1,225AR,S2 of the rim region
225AR are flush, along the vertical direction
Y, with the recessed portion side
210AR,S1,210AR,S2. Therefore, the top profiles of the side edge portions
225S1,225S2, of the drawer cover
225, and of the side edge portions
210S1,210S2 are flush to each other along the vertical direction
Y and define, as a whole, a top profile of the drawer
115.
[0071] According to the present invention, as visible in
Figures 2A,
2B and
2C, the laundry appliance
100 preferably comprises an access component associated with the drawer
115 (and, particularly, to the access openings
2301,2302) for selectively covering and uncovering the access openings
2301,2302 thereby respectively preventing and allowing access to the respective multi-dose
compartments
2201,2202 (in the exemplary considered embodiment, no access components are provided for selectively
covering and uncovering the access mouths of the mono-dose compartments
2151,2152, however this should not be construed as a limitation).
[0072] The access component may for example be a door
245, the door being advantageously coupled or coupleable to the drawer cover
225 at the respective access opening
2301,2302. According to the advantageous embodiment herein considered and illustrated, the
door
245 is a flap door pivotally coupled to the drawer cover
225 so as to be actuatable by the user between an open position (shown in the bottom
drawing of
Figure 2A) and a closed position (shown in the top drawing of
Figure 2A) for jointly uncovering and covering, respectively, both the access openings
2301,2302.
[0073] In other words, according to the present invention, a single door
245 associated with both access openings
2301,2302 is provided. Having a single door
245 for covering and uncovering both the access openings
2301,2302 jointly (
i.e., concurrently) makes user experience extremely simple; in fact, in doing so, no associations
between doors and access openings have to be remembered by the user, thus avoiding
risks of confusion that could be frustrating for the user. Moreover, having a single
door
245 for jointly covering and uncovering both the access openings
2301,2302 makes the drawer aesthetics more pleasant, and capable of giving to the user a feeling
of attention to detail and refinement: in fact, having a single door
245 instead of two or more adjacent doors avoids differences in heights among the doors
(due to unavoidable manufacturing tolerances), and an excessive number of unaesthetic
door contour lines which would be in contrast with a fine and minimal appearance of
the rest of the drawer.
[0074] Preferably, as illustrated, the door
245 fits the recessed area
225A of the drawer cover
225 and, preferably, the recessed area of the drawer body
210 (
i.e., the recessed side portions
210AR,S1,210AR,S2) and is flush with the top profile of the drawer
115 when the door
245 is in the closed position. However, same considerations apply for alternative embodiments
of the present invention in which the drawer
115 comprises no drawer cover
225 in correspondence of the door
245; in these embodiments, the door
245 is advantageously shaped to fit the recessed area of the drawer body
210 (
i.e., the recessed side portions
210AR,S1,210AR,S2) and to be flush with the top profile of the drawer body
210 (
i.e., of the side edge portions
210S1,210S2 thereof) when the door
245 is in the closed position.
[0075] The door
245 preferably comprises an abutment portion
245AB that, when the door
245 is in the closed position, abuts on the rim region
225AR (preferably on a portion thereof, and more preferably on the front portion
225AR,F thereof). The abutment portion
245AB is preferably part of a sealing member of the door
245, the sealing member being for example made of synthetic rubber or thermoplastic materials,
or other materials having sufficiently resilient properties to ensure good adherence
when coming in contact with the rim region
225AR (
i.e., when the door
245 in the closed position). The sealing member is advantageously overmolded to a body
245B of the door
245, the body
245B of the door
245 being for example made of same or similar plastic material of most of the drawer
115 (for example, a plastic rigid material).
[0076] According to an embodiment of the present invention, the door
245 further comprises one or more grip portions for actuating the door
245. Preferably, as illustrated, the door
245 comprises two grip portions
245G1,245G2, each one facing a respective side portion
245AR,S1,245AR,S2 of the rim region
245AR when the door
245 is in the closed position.
[0077] The grip portions
245G1,245G2 are preferably formed in a single piece with the abutment portion
245AB, the grip portions
245G1,245G2 being therefore part of the sealing member. More preferably, the grip portions
245G1,245G2 are designed such that, when the door
245 is in the closed position, each grip portion
245G1,245G2 is flush (along the vertical direction
Z) with the respective side edge portion
210S1,210S2 of the drawer body
210 (and, when the drawer cover
225 is provided, with the respective side edge portion
225S1,225S2 thereof). Even more preferably, the grip portions
245G1,245G2 are designed such that, when the door
245 is in the closed position, each grip portion
245G1,245G2 is spaced apart from the multi-dose compartment
2201,2202 along the vertical direction
Z. Still more preferably, each grip portion
245G1,245G2 has a thickness lower than the thickness of the abutment portion
245AB, such that, when the door
245 is in the closed position (and the abutment portion
245AB abuts the front portion
245AR,F of the rim region
245AR, when provided) each grip portion
245G1,245G2 and the respective faced recessed side portion
210AR,S1,210AR,S2 (and eventually the respective faced side portion
225AR,S1,225AR,S2 of the rim region
245AR, when provided) are spaced apart from each other (along the vertical direction
Z) by a gap (visible in the top drawing of
Figure 2A) that allows the user to grasp the grip portion
245G1,245G2.
[0078] Having a single door
245 for jointly covering and uncovering both the access openings
2301,2302, and having two grip portions
245G1,245G2 for actuating the door
245 makes user experience extremely simple; in fact, in doing so, no association between
doors, access openings and grip portions have to be remembered by the user, thus avoiding
risks of confusion that could be frustrating for the user.
[0079] According to an embodiment of the present invention, the door
245 is a marked component,
i.e. it has a respective marker. Preferably, the marker is provided in the sealing member.
More preferably, the marker is provided on one or more of (preferably both) the grip
portions
245G1,245G2 (so that the user can quickly identify the portion(s) of the door
245 to be grasped for its opening). Additionally or alternatively, the marker is preferably
provided on the abutment portion
245AB (so that the user can quickly identify the door
245, and, in the example at issue, quickly understand that a single door is provided for
jointly covering two distinct multi-dose compartments
2201,2202).
[0080] Preferably, this marker comprises an appearance feature standing out from a generally
uniform appearance of the drawer
115. For example, the appearance feature may comprise a color, more preferably a color
that stands out from a generally uniform color of the drawer
115; just as an example, in case that the drawer
115 has a generally uniform (
e.g., white) color (as in most of currently marketed laundry appliances), the color of
the sealing member may be a color different from the generally uniform color of the
drawer
115, the color of the sealing member being for example sufficiently different from the
generally uniform color of the drawer
115 to allow the user to visually detecting the sealing member at a first glance; just
as an example, the color of the sealing member may be red, blue, green, black, yellow,
or pink (or even a combination thereof and/or of other known colors). Even more preferably,
the color of the sealing member may be selected, among the group of any known colors,
as a color that, even from daily experience of other aspects of the human life, is
already a signifier in itself and therefore that any user is induced to associate
with a condition requiring and attracting his/her attention; examples of these colors
are red, which is commonly used to indicate dangers or prohibitions (
e.g., in road signs), and/or blue (which, for example, in road signs indicate obligation).
For ease of representation, in
Figures 2A-2D the markers are generally represented as a uniform grey color of the grip portions
245G1,245G2 and of the abutment portion
245AB to which the marker is preferably (although not exclusively) applied.
[0081] Additionally or alternatively to the color, the appearance feature may comprise one
or more graphical effects able to attract the attention of the user due to their aesthetical
appeal and/or to their unaccustomed use in the laundry appliance field. Examples of
these graphical effects comprise color shades or tones (for example, in case of a
drawer having a generally uniform color, the graphical effect may comprise a warmer
tone of the same color), mirror effects, chromed effects, satin finishes, and the
like.
[0082] Additionally or alternatively to the color and/or to the graphical effect(s), the
appearance feature may comprises one or more tactile effects. Examples of these tactile
effects comprise rough or knurled surfaces,
e.g. as opposed to a generally uniform smooth surface of the drawer
115.
[0083] Alternatively or, as herein assumed, additionally to the appearance features of the
marker, the marker preferably comprises a function indicator allowing the user to
recognize a function of the door
245 (or of a drawer part associated therewith). Each function indicator may for example
be a textual indicator and/or sign indicator.
[0084] Just as an example, the textual indicator may comprise a term indicating the function
of the respective component (for example, "door"), or an abbreviation thereof. Additionally
or alternatively, the textual indicator may comprise a term indicating the action
to be taken by the user for actuating the respective component (for example, "lift"
associated with the access component
245 and particularly to the grip portions
245G1,245G2). Additionally or alternatively, the textual indicator may comprise a letter (for
example, as illustrated in
Figures 2A-2C, the letters "A" and "B" provided on the door
245 and respectively associated with the multi-dose compartments
2201 and
2202 covered or uncovered by the door
245).
[0085] Just as an example, the sign indicator may comprise a symbol, preferably in a self-explanatory
form, such as the common symbols of washing detergent and softener respectively associated
with the multi-dose compartments
2201 and
2202 (as visible in
Figures 2A-2C), or symbols explaining or suggesting the action to be taken by the user for actuating
the respective component (for example, an upwards circular arrow for suggesting the
user the lifting movement necessary to actuate the door
245).
[0086] The function indicators may be formed at any convenient part of the door
245, or even in a proximity of it (for example, in case of function indicators including
relatively detailed instructions); just as an example, as visible in
Figures 2A-2C, the functional indicators associated with the multi-dose-compartments
2201,2202 are advantageously provided on a surface of the door
245 opposite to an inner surface of the door
245 that, when the door
245 is in the closed condition, faces the multi-dose compartments
2201,2202 (alternatively, the functional indicators may be provided on the inner surface or
on both inner and outer surfaces thereof).
[0087] As discussed above, in the example at issue the user interface
125 comprises one or more control elements for allowing the user to select a washing
cycle and to control one or more operating parameters of the selected washing cycle,
and one or more status indicators for indicating to the user a status of the laundry
appliance
100. According to an embodiment of the present invention, one or more of the operating
parameter(s) and the status indicator(s) is associated each one with a respective
one of said markers. In particular, when the marker comprises the function indicator
(
e.g., in the form of textual indicator and/or sign indicator) allowing the user to recognize
a function of the door
245, the same function indicator may be provided on the user interface
125 and associated with one or more of the operating parameters or of the status indicators.
Just as an example, the textual indicator comprising the letters "A" and "B" provided
on the door
245 and respectively associated with the multi-dose compartments
2201 and
2202 may also be provided on the user interface
125 (and particularly on the control elements, such as the selection buttons for allowing
the user to select the desired multi-dose compartment). Just as another example, when
the marker comprises a sign indicator in the form of a symbol, the same symbol of
the component or of the function (
e.g., washing detergent and softener) is also provided on the user interface
125 (and, particularly, on the control elements (
e.g., selection buttons) for selecting the desired function or on the status indicator
for allowing to check the status of the respective component).
[0088] As mentioned above, the drawer
115 can be moved between the extracted and retracted positions by acting on the drawer
handle
205.
[0089] According to an exemplary, not limiting embodiment of the present invention, the
drawer handle
205 may be reversibly coupled or connected to the drawer body
210, for example by means of a coupling arrangement associated with the drawer
115. Preferably, although not necessarily, the coupling arrangement comprises sliding
means (such as the rail elements
210R1,210R2 visible in
Figure 2B) arranged on the drawer body
210 along the transversal direction
Y (which identifies a coupling direction between the drawer handle
205 and the drawer body
210) and sliding means (such as rail elements
205R1,205R2 visible in
Figure 2D) arranged on the drawer handle
225 along the transversal direction
Y. The rail elements
210R1,210R2 of the drawer body
210 are adapted to slidably engage with the rail elements
205R1,205R2 of the drawer handle
205 for allowing the drawer handle
205 to move with respect to the drawer body
210 along the transversal direction
Y. Preferably, in order to provide the reversible coupling of the drawer handle
205 to the drawer body
210 (
e.g., for easily carrying out cleaning or maintenance operations on the drawer
115), the coupling arrangement also comprises a detach component
250 configured to selectively prevent or allow the movement of the drawer handle
205 with respect to the drawer body
210 along the transversal direction
Y (whereby when such a movement is allowed, detachment or decoupling between the drawer
handle
205 and the drawer body
210 can be obtained).
[0090] According to a preferred embodiment of the present invention, the detach component
250 is a detent element located on an inner face of the drawer handle
205 and configured to be switched between a locked configuration, in which the detent
element
250 engages a corresponding detent region
255 (
e.g. a window, preferably a rectangular window, visible in
Figure 2B) in a front wall of the drawer body
210, and an unlocked configuration, in which the detent element
250 is disengaged from the detent region
255 thereby allowing the movement of the drawer handle
205 with respect to the drawer body
210 along the transversal direction
Y. Preferably, as visible in
Figures 2B and
2D, the detach component
250 comprises a detach actuator
250ACT actuatable for switching the detach component
250 between the locked and unlocked configurations. According to an alternative embodiments
of the present invention, the detach actuator
250ACT may be provided in the drawer body
210 instead of in the drawer handle
205, or the detach actuator
250ACT may be "distributed" between the drawer body
210 and the drawer handle
205.
[0091] According to an embodiment of the present invention, in addition to the door
245, one or more other marked components are provided. Preferably, the marked components
comprise, in addition to the door
245, one or more among the detach component
250, the adapter component
2151,AD, the extraction component
210E and the plug components
210P1,210P2. More preferably, the marked components comprise all among the detach component
250, the adapter component
2151,AD, the extraction component
210E and the plug components
210P1,210P2, so as to allow the user to visually identify all (or a relevant number of) the components
associated with the drawer
115 that can be manually actuated by the user while interacting with the drawer
115 (hereinafter referred to as a whole as actuatable components).
[0092] According to an embodiment of the present invention, the appearance feature of the
marker of the door
245 (
i.e., of the sealing member thereof) is common (thus referred to as common appearance feature
in the following) to the marker of the door
245 and to the marker(s) of the other marked component(s).
[0093] In
Figures 2A-2D the markers of the detach
250, adapter
2151,AD, extraction
210E and plug
210P1,210P2 components (or of the portions thereof to which the markers are preferably, although
not exclusively, applied) are generally represented as a same uniform grey color (similarly
to the general representation of the marker on the grip portions
245G1,245G2 and of the abutment portion
245AB of the door
245).
[0094] The detach component
250 is preferably marked; the marker is preferably (but not exclusively) provided on
the detach actuator
250ACT (so that the user can quickly identify the portion of the detach component
250 onto which push action has to be exerted for detaching the drawer handle
205 from the drawer body
210).
[0095] The adapter component
2151,AD is preferably marked; the marker is preferably (but not exclusively) provided on
the inclined edge
IE1,AD (so that the user can quickly identify the portion of the adapter component
2151,AD to be grasped for insertion and removal thereof into and from the mono-dose compartment
2151).
[0096] The extraction component
210E is preferably marked; the marker is preferably (but not exclusively) provided on
the extraction actuator
210E,ACT (so that the user can quickly identify the portion of the extraction component
210E onto which push action has to be exerted for extracting the drawer
115 from the drawer seat
120).
[0097] One or more of the plug components
210P1,210P2 are preferably marked, the markers are preferably provided on exposed surfaces of
the plug components
210P1,210P2 that, when the plug components
210P1,210P2 plug the respective emptying holes
210H1,210H2, are visible by the user (so that the user can quickly identify the plug components
210P1,210P2).
[0098] As should be readily understood, further components (or groups of further components)
of the drawer
115 may be marked in order to improve their identifiability. The further components (or
groups of further components) do not necessarily need to be actuatable components.
Moreover, each one of these further components (or groups of further components) may
have a respective further marker, different from the marker associated with the actuatable
components discussed above. According to an embodiment of the present invention, not
shown, the further markers may be provided on portions of the mono-dose compartments
2151,2152 in order to better identify them and, for example, distinguish them from the multi-dose
compartments
2201,2202. The further markers may for example have a one or more further common appearance
features different from the common appearance feature discussed above and, preferably,
from the generally uniform appearance of most of the drawer
115. Just as an example the mono-dose compartments
2151,2152, and particularly the access mouths thereof, may have a color different from the
color associated with the markers and from the color of most of the drawer
115.
[0099] Naturally, in order to satisfy local and specific requirements, a person skilled
in the art may apply to the invention described above many logical and/or physical
modifications and alterations. More specifically, although the invention has been
described with a certain degree of particularity with reference to preferred embodiments
thereof, it should be understood that various omissions, substitutions and changes
in the form and details as well as other embodiments are possible. In particular,
different embodiments of the invention may even be practiced without the specific
details (such as the numeric examples) set forth in the preceding description for
providing a more thorough understanding thereof; on the contrary, well known features
may have been omitted or simplified in order not to obscure the description with unnecessary
particulars.
