- The present invention relates to an electric household appliance. In particular, the electric household appliance of the invention is intended to be inserted in a furniture system.
- More in detail, the electric household appliance of the invention is intended to be adapted to any existing furniture system, independently from the position of the hinges of the doors. Usually, in the design of a kitchen or of a laundry room furniture, there is an aesthetical need of uniformity, that leads users to cover the front surface of the electric household appliances with doors having the same look of the surrounding furniture.
- Nevertheless, the presence of a front door in a household appliance, for example in a washing machine, or in a drying machine, the different height of the machine compared with the one of the surrounding furniture, recesses, and position of the machine along a wall of the room, impact on the final look and functionality of the door.
- Existing electric household appliances are equipped with systems which allow adapting the position of the door in order to align the height of the door with the one of the surrounding furniture.
- A drawback of this known machine is that, depending on the position of the electric household appliance in the room, e.g. the door could require hinges at the left side of the front panel, or at its right side, so that a left sided machine, or a right sided one shall be bought.
- Accordingly, due to a change of the furniture, or a move into an other room, or house, a new electric household appliance shall be bought every time such needs change.
- The need of an electric household appliance flexible and adaptable to different furniture needs remains. Main aim of the invention is then to overcome the aforementioned drawbacks of the known machines and to provide an electric household appliance that is easy to be adapted to existing furniture.
- In particular, aim of the invention is to provide an electric household appliance that is easy to be assembled with a panel, independent on the position of the machine in a room.
- Another aim of the invention is to realize an electric household appliance equipped with a fixing system for an outer door, which is simple to be used and to be adapted to the needs of the user. These tasks, as well as other purposes that will be apparent hereinafter, are achieved by an electric household appliance according to the attached independent claim, to which reference is made in full.

supports 11, one for each end of thefirst side 4 or thesecond side 5 in which thepanel 6 has to be retained; preferably afirst support 11 contains a retainingelement 13, and asecond support 11 contains ashock absorbing element 14, for example an elastic element. - In a favorite variant of such detail of the invention (
figures 16-17 ), the retainingelement 13 or theshock absorbing element 14 may be coupled to thesupport 11 being housed in aremovable shell 18. - In an alternative variant, the retaining
element 13 or the shock absorbing element may be coupled to thesupport 11 being housed in ahousing 18A (seefigures 5-9 and14-15 ) of thesame support 11, for example being interlocked with each other. - The first embodiment of the pin elements preferably is a second sliding
element 15, to be slidably inserted in one of the twosecond slots 32, preferably the lower one, i.e. the one closer to theexit 37 of the vertical cavity of theseat 30. - More preferably, the second sliding
element 15 has a hookedend 17, to be inserted in and hung tosecond slot 32 of theseat 30, acting as a retainingelement 15 for a frontal constraint of the retainingdevice 10. - Preferably or alternatively, a further kind of pin element can be provided; for example, a second pin element can be a
snap element 16, configured to be inserted in the lowersecond slot 32, preferably in the same slot where the retainingelement 15 is inserted, for a sliding block of the retainingdevice 10. E.g. thesnap element 16 may be an elastically axially displaceable element, in particular an arch element, fixed to the support at one or both ends of the arch (in the latter, the snap force is higher), with a pin element at the peak. In such case, one ormore side openings 19 may be provided on the lateral side of thesupport 11, to allow the insertion of a tool for compressing thesnap element 16 and allowing the removal of thesupport 11 from theseat 30, through the extraction of the pin from thesecond slot 32. - In preferred embodiments of the invention, not shown, only one or two of the above described
pin elements - According to the invention, in an alternative embodiment, also a kit for coupling an outer panel to a wall of the casing of an electric household appliance may be provided, comprising:
- hinge device for fixing the outer panel in a pivotably manner to the wall of the casing, preferably in correspondence to the first vertical side, and
- retaining device, preferably in correspondence to the second vertical side, for holding the outer panel in a position facing the wall of the casing in order to conceal, at least partially, the wall.
- Analogously with the invention of the
figures 1-15 , the hinge device preferably comprise a hinge suitable for pivotably connecting the outer panel to the wall of the casing, a tightening device suitable for securing the hinge to the outer panel and to the wall of the casing and preferably an adjusting plate to slidably receive the tightening device, while the retaining device comprises a support to be coupled with the outer panel. Furthermore, the kit comprises also a seat to be fixed for each side, suitable for housing alternatively the hinge device and the retaining device, so that the hinge device and the retaining device are interchangeable from the first side to the second side and vice versa. - During use, the user installs the
household appliance 1 of the invention in the already existing furniture of the room, and then chooses the side on which the hinge device, supposed to pivotably fix thepanel 6 to theappliance 1, shall be placed. - Once the
side 5 has been chosen, the user inserts each slidingelement 22 of thehinge device 20 into therespective entrance 35 of eachseat 30 on the chosen side 5 (figure 10 ). - The sliding
element 22 is hung on theentrance 35 by itshooked end 25, so that thethird slots 28 are in correspondence with thesecond slots 32 of theseat 30. Thesupport 21 of the hinge device is preferably hung to the slidingelement 22, by inserting thehooked end 25 into theslot 26 of the same support 21 (figures 11-13 ). - Advantageously, the
support 21 is symmetrical in respect of the horizontal axis (when looking at the support while hung to the sliding element), providing anotherfirst slot 26 at the bottom of the support, so that the user may rotate it of 180° in case theother side 4 was chosen. Thesupport 21 could be also symmetrical in respect of the vertical axis (when looking at the support while hung to the sliding element), even if in the attached drawings thesecond slots 27 are not. In any case, since thefirst slots 26 have a length almost corresponding to the length of thewhole support 21, thesame support 21 may preferably slide on thehooked end 25 along thefirst slot 26 until thesecond slots 27 are in correspondence with thesecond slots 32 of theseat 30 and with thethird slots 28 of the slidingelement 22, and pinelements 24 may pass through all theslots - A
hinge 23 is placed directly in contact with thesupport 21, at the slots for the tightening means 24 in correspondence with theslots support 21, which is sandwiching theseat 30 with the slidingelement 22; there is also the possibility of adjusting the height of the same hinge, by sliding the tightening means 24 along the length of thesecond slot 32 of theseat 30. - The
hinge 23 is further fixed to thepanel 6 in a known way, such as by fastening means / glue. - On the
other side 4, the user places the retainingdevice 10 facing with the seat 30 (figures 5-9 ,14-15 ). - In particular, the sliding
element 12 is placed in front of therecess 34, while the second slidingelement 15 is placed in front of the lower of the two second slots 32 (figure 6A ), according to a first direction A perpendicular to thefront wall 3. - Just dragging down the
support 11 downwards along a second direction B parallel to thefront wall 3, the slidingelement 12 engages with thefirst slot 31, while thehooked end 17 of the second slidingelement 15 enters the lower of thesecond slots 32, then the second slidingelement 15 engages with saidsecond slot 32 avoiding a tilt of thesupport 11. - In the meanwhile, the
snap element 16 is elastically displaced towards theseat 30 and, while the second slidingelement 15 enters and engages with thesecond slot 32, the snap element slides along theprotrusion 33 according to the second direction B (fig. 6A ). - As soon as both the sliding
elements snap element 16 enters the lowersecond slot 32 together with the second slidingelement 15. - The sliding
elements support 11 from front falling. - The
snap element 16 advantageously prevents vibration and also avoids the support accidentally disassembling by dragging upwards from thefirst slot 31 and thesecond slot 32. - Furthermore, the
support 11 is prevented from tilting or rotating. - The ferromagnetic element placed in a corresponding position on the
panel 6 will be now attracted by themagnet 13 of the retainingelement 10, so that thepanel 6 will be kept closed, concealing thewall 3, while the eventual shock absorbing element of thesecond support 11 is able to absorb the impact of thepanel 6 while it is closed. - If a change of side is requested for the
panel 6, thehinge system 20 may be easily removed just unscrewing the pin / fixingelements 24 and extracting the slidingelement 22 from thefirst slot 31. Removal of thesupports 11 from theseat 30 simply requires inserting an elongated element (for example, a "flat blade" screwdriver) into theside opening 19, in order to unsnap the snap-fit element 16 from the lowersecond slot 32. - Subsequent to the removal of the retaining
system 10 and of thehinge system 20, they may be switched in the respectiveopposite sides - The invention thus conceived can be subjected to numerous modifications and variants all falling within the scope of the inventive concept. In addition, all details can be replaced by other technically equivalent elements. In practice, all the materials used, as well as the shapes and contingent dimensions, may vary depending on the requirements without departing from the scope of protection of the following claims.
