Title: Drawer for laundry appliance

Description:
This application is a U.S. National Phase application of PCT International Application No. PCT/EP2019/072618, filed Aug. 23, 2019, which claims the benefit of European Application No. 18191658.6, filed Aug. 30, 2018, both of which are incorporated by reference herein. 
     BACKGROUND OF THE PRESENT INVENTION 
     Field of the Present Invention 
     The present invention generally relates to the field of laundry appliances, and particularly to appliances for treating, e.g., washing, rinsing, and/or drying items (such as linen, clothes, garments, and the like), such as laundry washing machines, laundry drying machines, and combined laundry washing and drying machines. Specifically, the present invention relates to a drawer for a laundry appliance. 
     Overview of the Related Art 
     As it is well known, laundry appliances comprise a laundry treatment chamber wherein items to be treated (e.g., washed, rinsed and/or dried) are placed to be subjected to various laundry treatment operations. 
     Making reference to a laundry washing machine (but similar considerations also apply to combined laundry washing and drying machines), such laundry treatment operations involve the use of detergent substances, in powder and/or in liquid form, and of possible additional substances, such as for example softening agents, and rinsing agents, which will be defined in the present description as a whole as “washing agents”. 
     During some phases of laundry treatment operations, amounts of such washing agents should be delivered into the laundry treatment chamber in a controlled way. For this purpose, the laundry washing machine is equipped with a washing agents dispensing system comprising one or more washing agent containers adapted to be loaded with amounts of washing agents, and delivery devices for delivering into the laundry treatment chamber controlled amounts of the washing agents contained in the washing agent containers. 
     Making reference to a front-loading washing machine, the washing agent containers of the dispensing system are usually implemented as compartments of a drawer-shaped support structure, hereinafter simply referred to as dispensing drawer, which can be (at least partially) extracted from a front portion of the washing machine cabinet. 
     As it is well known to those skilled in the art, the compartments of the dispensing drawer can be configured to be loaded by a user with individual doses of washing agents, e.g., with an amount of washing agent necessary for a laundry treatment cycle on a single load of items, or may have a larger capacity sufficient to store more doses of washing agents, adapted to be used for more laundry treatment cycles on a plurality of loads of items. 
     Making reference instead to a laundry drying machine of the condensation type, the condensed (hence, liquid) moisture generated by the condensing of the process air has to be drained into a proper collection container. In this case as well, the container for collecting condensed moisture may be implemented as a compartment of a drawer-shaped support structure which can be manually extracted from the laundry drying machine and emptied by a user. 
     Therefore, in view of the above, a generic laundry appliance is usually equipped with a storage drawer (e.g., a dispensing drawer for dispensing washing agents into the laundry treatment chamber of a laundry washing machine or a drawer-shaped support structure for collecting condensed moisture of a laundry-drying machine of the condensation type) adapted to contain washing agents or condensed moisture which can be extracted/inserted from/into the laundry appliance cabinet along an extraction/insertion direction, usually perpendicular to the wall of the cabinet where the storage drawer is located. Such storage drawer is usually provided with a suitable handle designed to be used by an user for easily extracting/inserting the storage drawer from/into the cabinet of the laundry appliance. 
     If the storage drawer is not accurately cleaned from time to time, washing agent residuals and/or stagnant water may cause washing agent delivery devices to clog and/or bad smelling to generate. 
     For this reason, it is known to have storage drawers which are capable of being easily separated from the cabinet of the laundry appliance for being subjected to washing/rinsing operations. For example, a storage drawer may be completely pulled out and disengaged from the laundry appliance for being washed under a flow of fresh water, e.g., sourced by a faucet. 
     In order to easy the cleaning operations of the storage drawer and allow the latter to be cleaned in a more thoroughly way, the storage drawer should be advantageously designed to allow the detachment of the handle from the rest of the storage drawer (storage drawer body). Moreover, said detachment action for the drawer cleaning should be such to prevent the damage/wear of the handle. 
     For this reason, storage drawers exists which have the handle that is connectable with the storage drawer body (usually, with the front portion thereof) in a releasable way through a suitable coupling arrangement. 
     According to a solution known in the art, the handle is coupled with the storage drawer body through a coupling arrangement comprising tooth elements located on the internal side of the handle (i.e., the side of the handle facing the storage drawer body when the former is coupled with latter) and adapted to engage corresponding seats located on the front portion of the storage drawer body. This kind of arrangement provides for a frontal snap-fit coupling, according to which the handle is coupled to the front portion of the storage drawer body from the front, i.e., along a direction parallel to the storage drawer extraction/insertion direction. 
     SUMMARY OF THE PRESENT INVENTION 
     Applicant has observed that the abovementioned known solution for connecting in a releasable way a handle with a storage drawer body through a frontal snap-fit coupling is not efficient, being affected by several drawbacks. 
     If a small number of tooth elements was used (e.g., a single tooth element), the coupling between handle and storage drawer body may become too loose. This is a serious drawback, because the handle can accidentally detach from the storage drawer body, or worse, some of the tooth elements can broke, especially when the storage drawer body is quite heavy (e.g., when the storage drawer is a large capacity dispensing drawer loaded with a large amount of washing agents). 
     Therefore, in order to provide a sufficiently strong mechanical coupling between handle and storage drawer body using a frontal snap-fit coupling of the kind described above, a high number of tooth elements should be required on the internal side of the handle. However, having a high number of tooth elements located on the internal side of the handle makes the operations for detaching/attaching the handle from/to the storage drawer body very laborious and not comfortable. 
     In view of the above, Applicant has tackled the problem of devising a new solution for a storage drawer which is not affected by the abovementioned drawbacks. 
     More specifically, the Applicant provided for a storage drawer in which the handle is connected to the storage drawer body in a releasable way by means of a coupling arrangement that is stable, robust, resistant to breaks, and at the same time that allows to detach/attach the handle from/to the storage drawer body in an easy, fast and efficient way.

         a locked configuration, in which the detent element  250  engages a corresponding detent region  255  on the drawer body, e.g., on the support wall  220 , blocking the movement of the drawer handle  140  with respect to the drawer body  135  along direction z, and   an unlocked configuration, in which the detent element  250  is disengaged from the detent region  255 , to allow the movement of the drawer handle  140  with respect to the drawer body  135  along direction z.       

     According to an embodiment of the present invention, the detent region  255  comprises a window opened in the support wall  220 , for example a rectangular window. 
     According to an alternative embodiment of the present invention, the detent element  250  is located on the drawer body, e.g., on the support wall  220 , while the detent region  255  is located on the drawer handle  140 , e.g., on the inner face  218  thereof. 
     In order to better illustrate the detent element  250  according to an embodiment of the present invention, reference will be now made also to  FIGS. 4 and 5 , wherein  FIG. 4  is a view from above of the dispensing drawer  125  in the extracted position, with the drawer handle  140  fastened to the drawer body  135  and with a portion thereof that is partially sectioned along a section plane parallel to directions x and z, and  FIG. 5  is a section view of the dispensing drawer  125  of  FIG. 4  taken from a section plane parallel to directions x and y and containing the line V-V. 
     According to an embodiment of the present invention, the detent element  250  comprises a detent hook member  260  comprising at least one hook and supported by a resilient member  270 . The resilient member  270 , for example a strip element, has, along direction z, a first end connected to the inner face  218  of the drawer handle  140  and a second end connected to the detent hook member  260 . The resilient member  270  protrudes from the inner face  218  of the drawer handle  140 . 
     According to an embodiment of the present invention, the resilient member  270  is designed to exert a resilient force, preferably pushing the detent hook member  260  against the support wall  220  of the drawer body  135 . More particularly, the resilient member  270  is designed in such a way that, when the detent element  250  is in the locked configuration, the detent hook member  260  is pushed against the detent region  255 . 
     According to an embodiment of the present invention, the shape of the detent region  255  and the shape of the detent hook member  260  are such that, when in the locked configuration, the detent hook member  260  fits in the detent region  255 , with the hook(s) of the detent hook member  260  that pass through the window of the detent region  255  and are in abutment with side borders of the latter, inhibiting the movement of the drawer handle  140  with respect to the drawer body  135  along direction z. 
     According to an embodiment of the present invention, the detent element  250  is arranged on the inner face  218  of the drawer handle  140  in such a way to be located between the upper drawer handle rail element  215   a  and the lower drawer handle rail element  215   b.    
     According to an embodiment of the present invention, an actuator element is provided for the user manual switching of the blocking device. 
     According to an embodiment of the present invention, the actuator element comprises an actuator portion  280  included in the detent hook member  260  and designed to be pushed for disengaging the detent element  250  from the detent region  255 . By pushing the actuator portion  280 , the detent hook member  260  is pushed away from the detent region  255  against the resilient force exerted by the resilient member  270 . 
     The concepts of the present invention can be also applied in case the actuator element has a different structure and/or is located in a different position, such as for example not directly included in the detent hook member  260 . 
     According to an embodiment of the present invention, the drawer body  135  comprises at its front portion a recessed portion defining a free space  290  behind the support wall  220  to allow a user to reach the detention region  255  and push the actuator portion  280  (when the detent element  250  is in the locked configuration) for disengaging the detent element  250  from the detent region  255 . 
     When the detent element  250  is in the locked configuration (situation depicted in  FIGS. 2A and 3A ), the drawer handle  140  is strongly fastened to the drawer body  135 , and the former cannot slide with respect to the latter because the only movement allowed by the rail elements of the coupling arrangement (i.e., along direction z) is blocked by the detent element  250 , since the detent hook member  260  fits in the detent region  255 , with the hook(s) of the detent hook member  260  that pass through the window of the detent region  255  and are in abutment with side borders of the latter. 
     In order to switch the detent element  250  from the locked configuration to the unlocked configuration, the user pushes the actuator portion  280 , preferably reaching the detention region  255  through the free space  290  behind the support wall  220 , causing the detent element  250  to disengage from the detent region  255 . In this way, the drawer handle  140  can be slid with respect to the drawer body  135  along direction z by means of the rail elements of the coupling arrangement (see  FIGS. 2B and 3B ) until the drawer handle rail elements  215   a ,  215   b  disengage the drawer body rail elements  210   a ,  210   b , entirely detaching the drawer handle  140  from the drawer body  135  (see  FIGS. 2C and 3C ). 
     In order to attach again the drawer handle  140  to the drawer body  135 , it is sufficient to position the drawer handle  140  to the side of the drawer body  135  in such a way to align the drawer handle rail elements  215   a ,  215   b  to the drawer body rail elements  210   a ,  210   b , and move the drawer handle  140  along direction z in order to have the drawer handle rail elements  215   a ,  215   b  that slidingly engage again the drawer body rail elements  210   a ,  210   b . The sliding movement along direction z of the drawer handle  140  with respect to the drawer body  135  is then automatically stopped when the detent hook member  260  (which during the sliding movement is pushed against the support wall  220  by the resilient member  270 ) aligns itself with the detent region  255 . Indeed, in this condition, the resilient force exerted by the resilient member  270  causes the detent hook member  260  to engage the detent region  255 , thus causing the detent element  250  to switch back into the locked configuration. 
     The solutions according to the embodiments of the invention described herein provide for a releasable connection between drawer handle and drawer body that is stable, robust, resistant to breaks, and at the same time allows to detach/attach the drawer handle from/to the drawer body in an easy, fast and efficient way. 
     The present invention has been here described in detail making reference to some possible embodiments thereof. Other embodiments are possible and at the reach of the person skilled in the art.
