Description

Field of the invention

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

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.
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.
The drawers of currently marketed laundry appliances, especially of high quality laundry appliances, comprise each one a relatively high number of actuatable components (for example, all or almost all of the above mentioned actuatable components).
These actuatable components, together with the remaining parts of the drawer, typically define as a whole a generally uniform and substantially impersonal appearance of the drawer.

Summary of invention

The Applicant has realized that a uniform and impersonal appearance of the 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.
Indeed, the Applicant has ascertained that a drawer having a uniform appearance and comprising a relatively high number of actuatable components may be disclouraging for the user, in that the actuatable components are not easily recognizable and/or actuatable by the user without resorting to the instruction manual of the laundry appliance or other forms of help or assistance.
As a result of this, many of the functionalities of the laundry appliance associated with the actuatable components are not exploited or fully exploited by the user, whereby user perception of the laundry appliance (and hence customer loyalty towards the laundry appliance manufacturer) may be negatively affected.
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 drawer with easily recognizable, easy to use and cheap actuatable components.

Detailed description of preferred embodiments of the invention

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).
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).
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 an 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.
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).
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 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 ) and a retracted position (shown in Figure 1B ). The drawer seat 120 is preferably provided on a top part of a cabinet front.
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.
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.
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 the purposes of the present disclosure, the status indicators are 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).
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.
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).
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).
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. Additionally, as herein exemplary assumed, or alternatively, the drawer 115 preferably comprises one 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, 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.
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 215_1,AD ) configured to be reversibly housed into the mono-dose compartment 215₁
In the exemplary illustrated embodiment, the adapter component 215_1,AD comprises a container (for example, a cup-shaped container) C_1,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 215_1,AD advantageously comprises a siphon pipe SP_1,AD (preferably, formed in a single piece with the container C_1,AD ) to induce a siphon phenomenon, and a siphon cap SC_1,AD coupled (or adapted to be coupled) to the siphon pipe SP_1,AD: when the liquid washing detergent in the container C_1,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 SP_1,AD.
Preferably, as visible in Figure 2B , the container C_1,AD fits the access mouth of the mono-dose compartment 215₁, exception made for an inclined edge IE_1,AD of the container C_1,AD. When the container C_1,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 IE_1,AD of the container C_1,AD, whereby the inclined edge IE_1,AD of the container C_1,AD defines a grip portion adapted to be grasped for easily actuating (e.g., inserting and removed into and from the mono-dose compartment 215₁ ) the container C_1,AD (or, more generally, the adapter component 215_1,AD ). According to a preferred embodiment of the present invention, at least part of the inclined edge IE_1,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 IE_1,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.
In the example illustrated embodiment, a container (for example, a cup-shaped container) C_2,AD having a siphon pipe (not visible, and preferably formed in a single piece with the container C_2,AD ) to induce a siphon phenomenon is associated with the mono-dose compartment 215₂. Although not shown, the container C_2,AD may also comprise a grip portion (e.g., similar to the grip portion of the container C_1,AD ) to allow insertion and removal thereof into and from, respectively, the mono-dose compartment 215₂.
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 ).
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 ).
As visible in Figure 2B , one or more emptying holes each one associated with a respective multi-dose compartment 220₁,220₂ are 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 210_H1,210_H2 are provided in the drawer body 210, the emptying hole 210_H1 being associated with the multi-dose compartment 220₁ and the emptying hole 210_H2 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 210_H1,210_H2.
In the exemplary considered embodiment, each emptying hole 210_H1,210_H2 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 210_H1,210_H2 is advantageously closable or pluggable by means of a selectively removable plug component (or, concisely, plug) 210_P1,210_P2 (the plugs 210_P1,210_P2 being both visible in Figure 2B detached or removed from the respective emptying holes 210_H1,210_H2, whereas a plug covering the respective emptying hole, such as the plug 210_P1 covering the emptying hole 210_H1, is visible in Figure 2A ). Advantageously, each emptying hole 210_H1,210_H2 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 210_P1,210_P2 become accessible and can be removed to free the emptying holes 210_H1,210_H2. Therefore, upon sufficient extraction or pulling out of the drawer 115 and removal of the plug(s) 210_P1,210_P2, the treatment agent(s) in the multi-dose compartment(s) 220₁,220₂ is caused to flow outside through the respective emptying hole(s) 210_H1,210_H2, 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 210_H1,210_H2 being for example promoted by a proper slanting or other draining shape of a bottom wall of the drawer body 210).
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 210_E ).
For the purposes of the present disclosure, the extraction component 210_E 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 210_E comprises a releasable locking element 210_E,LOC for locking the extraction component 210_E in a slot 120s of the drawer seat 120 (thus firmly securing the extraction component 210_E to the drawer seat 120 during actuation of the extraction component 210_E ).
Preferably, the extraction component 210_E further comprises an extraction actuator 210_E,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 210_E comprises a catch portion 210_E,CAT adapted to engage a blocking portion (not shown) of the drawer body 210; more preferably, the extraction actuator 210_E,ACT is mechanically coupled to the catch portion 210_E,CAT for operating the extraction component 210_E between a first condition in which the catch portion 210_E,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 210_E,CAT disengages the blocking portion thereby allowing extraction of the drawer 115 from the drawer seat 120 (with the extraction component 210_E 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 210_E,LOC being fitted in the slot 120s). A more detailed description of the extraction component 210_E (and of embodiments thereof) can be found in EP2876197 , which is herein incorporated by reference.
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 one or more access openings each one for accessing a respective 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.
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 230_1L ). Each level indicator, such as the level indicator 230_1L, 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.
Preferably, although not necessarily, the access openings 230₁,230₂ are formed in the drawer cover 225 side by side along the transversal direction Y.
The access openings 230₁,230₂ are advantageously formed in an area 225_A 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).
Advantageously, the area 225_A 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 that a free area 240 is defined in the drawer cover 225 adapted to contain one or more pieces of information for the user. Exemplary pieces of information that may be contained in the free area 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.
According to the exemplary, not limiting, embodiment of the present invention, the area 225_A of the drawer cover 225 in which the access openings 230₁,230₂ are formed is a recessed area 225_A, the recessed area 225_A being recessed (along the vertical direction Z) with respect to a top profile of the drawer cover 225.
As better visible in Figure 2C , the recessed area 225_A preferably comprises a rim region 225_AR that substantially surrounds the access openings 230₁,230₂. The rim region 225_AR preferably comprises a front portion 225_AR,F that, in use, is proximal to the free region 240, and side portions 225_AR,S1,225_AR,S2. More preferably, each side portion 225_AR,S1,225_AR,S2 of the rim region 225_AR, or at least a relevant part thereof, opens to a respective side edge portion 225_S1,225_S2 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 225_AR,S1,225_AR,S2 of the rim region 225_AR.
As visible in Figures 2A , 2B and 2C , the laundry appliance 100 preferably comprises one or more access components associated with the drawer 115 for selectively covering and uncovering the access openings 230₁,230₂ for 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).
The access component may for example be a door 245 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. In other words, a single door 245 associated with both access openings 230₁,230₂ is assumed in the exemplary considered embodiment - in any case, in alternative embodiments of the present invention, not shown, two doors may be provided, each door being associated with a respective access opening 230₁,230₂.
Preferably, as illustrated, the door 245 fits the recessed area 225_A of the drawer cover 225 and is flush with the top profile of the drawer cover 225 when the door 245 is in the closed position.
The door 245 preferably comprises an abutment portion 245_AB that, when the door 245 is in the closed position, abuts on the front portion 225_AR,F of the rim region 225_AR. The abutment portion 245_AB 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 front portion 225_AR,F of the rim region 225_AR (i.e., door 245 in the closed position). The sealing member is advantageously overmolded to a body 245_B of the door 245, the body 245_B 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).
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 245_G1,245_G2, each one facing a respective side portion 245_AR,S1,245_AR,S2 of the rim region 245_AR when the door 245 is in the closed position.
The grip portions 245_G1,245_G2 are preferably formed in a single piece with the abutment portion 245_AB, the grip portions 245_G1,245_G2 being therefore part of the sealing member. More preferably, the grip portions 245_G1,245_G2 are designed such that, when the door 245 is in the closed position, each grip portion 245_G1,245_G2 is flush (along the vertical direction Z) with the respective side edge portion 225_S1,225_S2 of the drawer cover 225. Even more preferably, the grip portions 245_G1,245_G2 are designed such that, when the door 245 is in the closed position, each grip portion 245_G1,245_G2 is spaced apart from the multi-dose compartment 220₁,220₂ along the vertical direction Z. Still more preferably, each grip portion 245_G1,245_G2 has a thickness lower than the thickness of the abutment portion 245_AB, such that, when the door 245 is in the closed position and the abutment portion 245_AB abuts the front portion 245_AR,F of the rim region 245_AR, each grip portion 245_G1,245_G2 and the respective faced side portion 225_AR,S1,225_AR,S2 of the rim region 245_AR 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 245_G1,245_G2 . Having a single door 245 for jointly covering and uncovering both the access openings 230₁,230₂, and having two grip portions 245_G1,245_G2 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.
As mentioned above, the drawer 115 can be moved between the extracted and retracted positions by acting on the drawer handle 205.
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 210_R1,210_R2 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 205_R1,205_R2 visible in Figure 2D ) arranged on the drawer handle 225 along the transversal direction Y. The rail elements 210_R1,210_R2 of the drawer body 210 are adapted to slidably engage with the rail elements 205_R1,205_R2 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).
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) 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 250_ACT 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 250_ACT may be provided in the drawer body 210 instead of in the drawer handle 205, or the detach actuator 250_ACT may be "distributed" between the drawer body 210 and the drawer handle 205.
According to the principles of the present invention, two or more among the components associated with the drawer 115 that can be manually actuated by the user while interacting with the drawer 115 comprise, at least on respective portions thereof, respective markers - hereinafter, for the sake of conciseness, these actuatable components will be referred to as marked components. Advantageously, the markers provided on the marked components comprise one or more common appearance features for allowing the user to visually identify the actuatable components in the drawer 115.
According to an embodiment of the present invention, the marked components comprise two or more, preferably all, among the detach component 250, the adapter component 215_1,AD, the extraction component 210_E, the access component 245 and the plug components 210_P1,210_P2. For ease of representation, in Figures 2A-2D the markers are generally represented as a uniform grey color of the portions of the actuatable components to which the markers are preferably (although not exclusively) applied.
The detach component 250 is preferably marked; the marker is preferably (but not exclusively) provided on the detach actuator 250_ACT (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).
The adapter component 215_1,AD is preferably marked; the marker is preferably (but not exclusively) provided on the inclined edge IE_1,AD (so that the user can quickly identify the portion of the adapter component 215_1,AD to be grasped for insertion and removal thereof into and from the mono-dose compartment 215₁ ).
The extraction component 210_E is preferably marked; the marker is preferably (but not exclusively) provided on the extraction actuator 210_E,ACT (so that the user can quickly identify the portion of the extraction component 210_E onto which push action has to be exerted for extracting the drawer 115 from the drawer seat 120).
The access component 245 is preferably marked; the marker is preferably (but not exclusively) provided on one or more of (preferably both) the grip portions 245_G1,245_G2 (so that the user can quickly identify the portion(s) of the access component 245 to be grasped for its opening). Additionally or alternatively, the marker is preferably provided on the abutment portion 245_AB (so that the user can quickly identify the access component 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 ).
One or more of the plug components 210_P1,210_P2 are preferably marked, the markers are preferably provided on exposed surfaces of the plug components 210_P1,210_P2 that, when the plug components 210_P1,210_P2 plug the respective emptying holes 210_H1,210_H2, are visible by the user (so that the user can quickly identify the plug components 210_P1,210_P2 ).
Preferably, the common appearance feature stands out from a generally uniform appearance of the drawer 115. For example, the common appearance feature may comprise a common color, more preferably a common 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 common color may be a color different from the generally uniform color of the drawer 115, the common color being for example sufficiently different from the generally uniform color of the drawer 115 to allow the user to visually detecting the marked components at a first glance; just as an example, the common color may be red, blue, green, black, yellow, or pink (or even a combination thereof and/or of other known colors). Even more preferably, the common color 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).
Additionally or alternatively to the common color, the common 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.
Additionally or alternatively to the common color and/or to the graphical effect(s), the common 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.
Alternatively or, as herein assumed, additionally to the common appearance features of the markers, each marker preferably comprises a function indicator allowing the user to recognize a function of the respective marked component (or of a drawer part associated therewith). Each function indicator may for example be a textual indicator and/or sign indicator.
Just as an example, the textual indicator may comprise a term indicating the function of the respective component (for example, "plug"), 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, "push" associated with the detach actuator 250_ACT, "pull" associated with the plug components 210_P1,210_P2, "lift" associated with the access component 245 and particularly to the grip portions 245_G1,245_G2 ). 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 access component 245 and respectively associated with the multi-dose compartments 220₁ and 220₂ covered or uncovered by the access component 245).
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 access component 245).
The function indicators may be formed at any convenient part of the actuatable component, 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 provided on a surface of the access component 245 opposite to an inner surface of the access component 245 that, when the access component 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).
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 respective marked component, 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 access component 245 and respectively associated with the multi-dose compartments 220i 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).
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.
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.
