DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

(14) Like elements are denoted by like reference signs throughout the figures.

(15) In FIGS. 1, 2, and 3 a laundry machine 1 is shown in perspective and front views. In the case shown, the laundry machine 1 is a washing machine, but the laundry machine of aspects of the invention can be a washing-drying machine or a dryer.

(16) The laundry machine 1 comprises a parallelepiped cabinet (or housing) 2. The cabinet 2 may be advantageously made of a frame covered by a metal sheet, e.g. a steel sheet.

(17) Cabinet 2 houses a chamber 3 for treating laundry. The chamber 3, in the case shown of a washing machine, is a drum 4 rotatably mounted within a tub (not visible) about a rotation axis RR. In the advantageous example shown in the attached figures, rotation axis RR is, when the machine is installed on the floor, in an operative position, like in the example shown in FIGS. 1 and 2, substantially horizontal, but in a different advantageous embodiment this axis RR can be inclined.

(18) As shown, the cabinet 2 of the laundry machine 1 may advantageously include a lid 5 for accessing a filter (not shown), a drawer 6 for a detergent, softening agent and/or other additives, as well as a control panel 7. These components may be missing and/or other components may be present on the cabinet 2.

(19) A porthole 8 for providing access to and tightly closing the chamber 3 is provided at the front wall of the cabinet 2, specifically at an opening 9 of the cabinet 2 and at an opening 3a of the chamber 3.

(20) A gasket (or bellows) 10 is provided at the opening 9 of the cabinet 2 and connects the border of this opening 9 to the inlet opening of the washing tub (not illustrated).

(21) A hinge 11 is provided to pivot the porthole 8 to the cabinet 2 so that it can be opened by rotating it about a vertical axis XX, as shown in FIG. 2. The hinge 11 is arranged in such a way that, when the porthole 8 is closed, its center of mass C11 (see e.g. FIG. 3) is located, with respect to the rotation axis RR, at a first angular position.

(22) Preferably, hinge 11 is arranged across, and more preferably centered across, a horizontal median plane HH of the porthole 8.

(23) Hinge 11 may be any conventional hinge, preferably of the type that is not visible when the porthole 8 is closed. In the embodiment shown in the figures, hinge 11 comprises a portion 11a (FIGS. 9, 10, 12) fixed to the cabinet 2, a seat 11b (FIGS. 9, 10, 12) for housing it provided in the porthole 8, and a hinge pin (not shown) extending in holes of the portion 11a and of the seat 11b, wherein holes 11c of the seat 11b are visible in FIGS. 9 and 12.

(24) An electromechanical lock 12 is provided between the porthole 8 and the cabinet 2. The lock 12 comprises a portion or first member fixed to the cabinet 2 and a portion or second, matching member fixed to the porthole 8 that cooperate with each other.

(25) The lock 12 is configured to avoid opening of the porthole during operation of the machine; and to possibly to avoid operation of the machine with the porthole open, by issuing a consent signal to an electronic control unit of the machine only when the porthole is closed and/or delay opening of the porthole after the end of an operation cycle. The electromechanical lock is therefore also an interlock.

(26) Advantageously the first member comprises a latch 13 protruding from the porthole 8 towards the cabinet 2visible in FIGS. 2, 9, 10 and 12and the second member comprises a latch retaining mechanism 14 for receiving the latch 13, positioned at the cabinet 2.

(27) The latch 13 is shown as a protrusion having an aperture 13a. The entire latch retaining mechanism 14 is not visible in the figures, only a seat for receiving the latch 13 is visible. The latch retaining mechanism 14 preferably includes, in a manner known per se, a mobile part which is configured to be movable between a retaining position, in which it engages the latch 13 so as to retain the porthole 8 in a closed condition, and an opening position it which it releases the latch 13 so as to allow the opening of the porthole 8. The mobile part of the latch retaining mechanism 14 at the cabinet 2 preferably interacts with an elastic element, for example a spring, which allows the releasing of the latch 13 when a releasing force is applied which is greater than a threshold force. The porthole 8 is therefore of the pull-to-open type, opened by applying a force beyond a threshold onto the porthole 8 away from the cabinet 2.

(28) The lock 12 is preferably arranged across, and more preferably centered across, the horizontal median plane HH of the porthole 8.

(29) The first member 13 of lock 12 is arranged in such a way that, when the porthole 8 is closed, its center of mass C12 (see e.g. FIG. 3) is located, with respect to the rotation axis RR, at a different angular position than the center of mass C11 of the hinge 11, preferably at a diametrically opposite angular position with respect to hinge 11.

(30) A grip-only handle 15 is provided at the porthole 8, to be gripped by a user for applying a pulling force onto the porthole 8 away from the cabinet 2.

(31) The porthole 8 is usually opened by pulling it outwards with enough force through the handle 15, but it can also be opened by pushing it from the inside of the drum 4, e.g. by a caught child thanks to its pull-to-open type construction.

(32) A grip-only handle 15 in connection with a pull-to-open porthole or lock has several advantages. It is easier and less expensive to manufacture than a pivotal handle operating a movable hook at the porthole, especially when it is one piece with a frame of the porthole 8 as discussed below. Moreover it is more robust than a pivotal handle.

(33) The grip-only handle 15 protrudes radially inwardly from the frame of the porthole 8, specifically from the inner circumferential edge of an outer frame 30 thereof (see below).

(34) The grip-only handle 15 is provided at a position which is not aligned or not corresponding with the position of the lock 12. The grip-only handle 15 is arranged such that, when the porthole 8 is closed, its center of mass C15 is located, with respect to the rotation axis RR, at a different angular position than the center of mass C12 of the first member 13 of the lock 12.

(35) The grip-only handle 15 is preferably located or arranged outside the horizontal median plane HH of the porthole 8. The grip-only handle 15 is thus offset with respect to horizontal median plane HH and the lock 12. In case of a large extent of the handle 15 and/or of the lock 12, the two might however overlap in part.

(36) In the case shown, wherein the porthole 8 is circular and it is hinged at its left (as viewed from the front of the laundry machine 1 when the porthole is closed), the hinge 11 is advantageously centered across a position at 9 o'clock or 180 in a conventional angular reference system, and the lock 12 is across a position at 3 o'clock or 0. Thus the centers of mass C11 and C12 of hinge 11 and first member 13 of lock 12 lie on the median plane HH when they are symmetric.

(37) In FIGS. 1 to 3, the grip-only handle 15 is shown arranged in the first quadrant, i.e. between 0 and 90. A vertical centerline VV of the porthole 8 is also indicated in FIG. 3 to easily identify the quadrants. Advantageously the grip-only handle 15 extends for an arc or circumference lying in the generally central portion of the first quadrant.

(38) In case the laundry machine 1 is to be arranged on top of another equipment or piece of furniture, like in the case of a dryer machine arranged on top of a washing machine, the grip-only handle 15 may be arranged in the fourth quadrant, i.e. between 270 and 360, as shown in FIG. 4.

(39) In case the laundry machine 1 is hinged at its right, and arranged on the floor, then the grip-only handle 15 may be arranged in the second quadrant, i.e. between 90 and 180 as shown in FIG. 5.

(40) Finally, in case the laundry machine 1 is hinged at its right, and arranged on top of another equipment or piece of furniture, as shown in FIG. 6, then the grip-only handle 15 may be arranged in the third quadrant, i.e. between 180 and 270.

(41) It is immediately recognized that in all four cases, even if the position of the centers of mass C11, C12, C15 is just estimated in the drawings, the grip-only handle 15 and the first member 13 of electromechanical lock 12 are arranged in such a way that, when the porthole 8 is closed, their centers of mass C15 and C12 are located, with respect to the rotation axis RR, at different angular positions.

(42) Moreover, in all four cases, the hinge 11 is arranged in such a way that, when the porthole 8 is closed, its center of mass C11 is located, with respect to the rotation axis RR, at a diametrically opposite angular position with respect to the center of mass C12 of the first member 13 of the electromechanical lock 12.

(43) Moreover, in all four cases the grip-only handle 15 and the first member 13 of the lock 12 are arranged such that, when the porthole is closed, their centers of mass C15, C12 are located, with respect to the rotation axis, at angular positions that are reciprocally spaced by less than 90.

(44) Thus, the grip-only handle 15 is preferably arranged in the half of the porthole about the electromechanical lock 12.

(45) In FIGS. 4-6 only an outer frame 30 of the porthole 8 is shown. A glass 32 of the porthole 8 is not shown. The construction of the porthole 8 is better disclosed below with reference to FIGS. 9, 10. Moreover, in those figures the position of the hinge 11 and of the lock 12 is indicated with the same reference numbers, even if the two are not visible.

(46) In FIG. 3-6 an identical handle 15 is shown in all four prefixed positions with respect to the frame 30. The handle 15 can be one piece with the frame 30 or positionable with respect to it. Before discussing how this can be achieved, it is noted that a handle 15a having a shape that is for example the mirror image of that of handle 15 may be provided in the case of porthole 8 hinged at its right, as shown in FIG. 7 and in FIG. 8.

(47) By the possibility of assembling a plurality of differently-shaped handles to a same porthole 8, the handle may always be configured with an ergonomic shape, as shown by the handle 15 in FIGS. 3, 4 and the handle 15a in FIGS. 7, 8.

(48) Such handle 15, 15a as shown in FIGS. 3, 4, 7, 8 has a body part 16, 16a cantilever or protruding radially inwardly from the outer frame 30 of the porthole 8, and extending along an arc of a circumference, e.g. of about 40-55. The body part 16 is preferably generally flat, as defined above. Preferably, the body part 16, 16a has a first edge 17, 17a that is an arc of circumference and adjoins the inner circumference of a slanted wall 35 (see below) of the outer frame 30 of the porthole 8. Preferably, the body part 16, 16a has a second or free edge 18, 18a cantilevered from the outer frame 30 of the porthole 8. Preferably the body part 16, 16a has a radial extent defined between the first edge 17, 17a and the free edge 18, 18a.

(49) The radial extent of the handle 15, 15a is preferably not constant. The free edge 18, 18a preferably adjoins or contacts the first edge 17, 17a at a first end 19, 19a of the handle 15, 15a that is upper in the mounted condition of the handle 15, 15a shown in FIGS. 3, 4, 7, 8, so that the radial extent of the handle 15, 15a at first end 19, 19a is zero. Moving towards a second end 20, 20a of the handle 15, 15a, opposite the first end 19, 19a and lower in the mounted condition of the handle 15, 15a shown in FIGS. 3, 4, 7, 8, the free edge 18, 18a is preferably first curved, having a radially inner convexity so that the radial extent of the handle 15, 15a increases to a maximum and then decreases again to a minimum greater than zero at a corner 21, 21a near the second end 20, 20a of the handle 15, 15a; after the corner 21, 21a the free edge 18, 18a is straight along an almost radial direction, until it adjoins or contacts the first edge 17, 17a at the second end 20, 20a of the handle 15, 15a.

(50) The handle 15, 15a thus preferably comprises a zone 22, 22a having a first or comparatively large radial extent, and a zone 23, 23a adjacent thereto having a second or comparatively small radial extent, smaller than the first radial extent, so that when the handle 15, 15a is gripped by a user, the zone 22, 22a having the first or comparatively large radial extent is gripped by the index finger and the medium finger, and the zone 23, 23a having the second or comparatively small radial extent is gripped by the ring finger and the little finger.

(51) The handle 15, 15a is therefore ergonomic when in the positions of FIGS. 3, 4, 7, 8, what helps the user to easily apply the required force to pull open the porthole 8.

(52) It is noted that usually dryer machines have a reversible porthole (left/right hinge), while washing and washing-dryer machines do not. This is because of the need of electrical connections in the latter type of machines to provide for safety closure of the chamber during operation of the machine.

(53) As discussed in the introductory part of the disclosure, the described arrangement of electromechanical lock 12 and handle 15 provides several advantages.

(54) An advantageous embodiment of the porthole 8 is now better disclosed with reference to FIGS. 9-12.

(55) The porthole 8 preferably comprises an outer frame 30, an inner frame 31 and a glass 32 sandwiched between the outer frame and the inner frame.

(56) The latch 13 is also shown in an exploded condition in FIGS. 9, 10.

(57) The outer frame 30 is a preferably generally annular member, having an outer circumferential edge 33 and a preferably beveled inner circumferential edge 34. Between the outer circumferential edge 33 and the inner circumferential edge 34, the outer frame 30 has a preferably slanted wall 35. The slanted wall 35 is preferably closer to the cabinet 2 at the outer circumferential edge 33 than at the inner circumferential edge 34, with reference to the closed condition of the porthole 8 (see FIG. 12).

(58) The inner frame 31 is also a preferably generally annular member, having a preferably tapered outer circumferential edge 36 and an inner circumferential edge 37. Preferably, between the outer circumferential edge 36 and the inner circumferential edge 37, the inner frame 31 has a flat wall 38.

(59) On the side coupling with each other, i.e. looking from the outside of the laundry machine 1 the inner side of outer frame 30 and the outer side of inner frame 31, the outer frame 30 and the inner frame 31 are preferably generally concave and advantageously they have a plurality of reinforcing ribs 39, 40, respectively. The outer frame 30 and the inner frame 31 have preferably also matching system for coupling to each other, with the interposition of the glass 32 and the latch 13. In the embodiment shown, the outer frame 30 has advantageously a plurality of internally threaded bushings 41 and the inner frame 31 advantageously has a plurality of holes 42 in corresponding prefixed positions, for receiving a plurality of screws or bolts (not shown). The ribs 39, 40 preferably extend about the bushings 41 and about the holes 42, respectively.

(60) Any other matching system may be suitable, such as snap pins, welding, gluing and similar.

(61) The seat 11b for the hinge 11 is advantageously made in the inner frame 31 and partly in the outer frame 30. Advantageously, in the inner frame 31, preferably diametrically opposite the centerline of the seat 11b for the hinge 11, there is an apertured seat 44 for the passage of the latch 13.

(62) Advantageously the inner side of the outer frame 30 has a protruding spacer 45 for abutting the latch 13 and keeping it out of the apertured seat 44 in inner frame 31.

(63) The glass 32 is preferably generally convex towards the inside of the laundry machine 1, protruding inwards from the inner frame 31. The shape of the glass 32 can depart from that shown.

(64) The glass 32 has preferably a circumferential rim 46 that is sandwiched between the outer frame 30 and the inner frame 31.

(65) Preferably, circumferential rim 46 has two diametrically opposite triangular protrusions 47. Advantageously, the inner frame 31 has, on its inner circumferential edge 37, notches 48 for housing the triangular protrusions 47 of the glass 32. Advantageously, the outer frame 30 has, on its inner side, triangular protrusions 49 defining seats for the triangular protrusions 47 of the glass 32. Thus, the rotational position of the glass 32 is well defined.

(66) Advantageously, further matching lugs 50 and recesses 51 are provided on the inner and outer frames 30, 31, respectively, to define the rotational mutual position thereof.

(67) Advantageously, the inner frame 31 has, on its inner circumferential edge 37, elastic retainers 51a defining the axial position of glass 32.

(68) The handle 15 is preferably one piece with the outer frame 30 and radially protrudes inward, cantilever from the inner circumferential edge 34. It is noted that in FIG. 10 the protruding portion of the handle 15 is hidden by the outer frame 30.

(69) As visible in FIG. 13a, the body part 16 of handle 15 is, advantageously, slightly recessed with respect to the slanted wall 35 of the outer frame 30 near its circumferential inner edge, and ends, at its free edge 18, flush with the slanted wall 35 of the outer frame 30 so as not to protrude from the outer frame 30 outwards, i.e. away from the cabinet 2 in the closed condition of the porthole 8.

(70) As visible in FIGS. 10-13 and 13A, the beveled inner circumferential edge 34 of the outer frame 30 is, advantageously, interrupted at the handle 15 by a wall 52 extending along part of a cylindrical surface flush with the radially inner edge of the beveled inner circumferential edge 34. Radially outer part 53 of the body portion 16 and lateral walls 54 advantageously fill the gap between the wall 52 and the beveled inner circumferential edge 34. Between the body portion 16 of the handle 15 and the inner circumferential edge 34 of the outer frame 30 there are also lateral walls 54a.

(71) The body portion 16 of the handle 15 is thus crossed by the wall 52 at an intermediate zone of the body portion 16. This enhances the strength of the handle 15.

(72) A plurality of reinforcing ribs 55 advantageously extend from the body portion 16. Advantageously, the ribs 55 are generally L-shaped bodies arranged at the corner between the wall 52 and the body portion 16, on the radially inner side of handle 15 facing, when the porthole 8 is closed, the chamber 3 and/or the cabinet 2.

(73) Reinforcing ribs 55 are preferably generally flat.

(74) Each rib 55 includes a long edge 56 adjoining the inner side of the body portion 16 from the wall 52 towards and preferably up to the free edge 18, and a short edge 57 adjoining at least part of the wall 52.

(75) The reinforcing ribs 55 may also extend shorter along the body portion 16 and/or longer along wall 52 (even up to its free edge) than shown.

(76) When molding the outer frame 30 with the handle 15 and its reinforcing ribs 55 in plastics, the material flowing in the ribs 55 would tend to make depressions on the opposite side (outer side) of the flat body 16 of the handle 15. In order to avoid these depressions to be seen from the front of the laundry machine 1, the ribs 55 should be made enough thin. On the other hand, the ribs 55 should be made enough thick and/or close to each other as to provide enough reinforcement against the flexural stress during opening of the porthole 8. A skilled in the art will find a proper compromise between the two opposite requirements without the exercise of inventive skills.

(77) Preferably, but not necessarily, the reinforcing ribs 55 may have a thickness, e.g. of 1.2 mm, that is at most 40% of the thickness of the body portion 15, the latter being e.g. of 3 mm; the distance between reinforcing ribs 55 may be shorter than or equal to 2.8 mm. With those figures, there are about 25 reinforcing ribs 55 in 100 mm of length of the body portion 16.

(78) The ribs 55 may extend parallel to each other as shown, or each rib 55 can extend in a radial plane.

(79) The reinforcing ribs 55 also improve the grip on the handle 15 because they avoid slipping of the hand, especially a wet hand as may well occur when dealing with washing laundry.

(80) The handle 15, 15a can be made one piece with the outer frame 30or generally speaking with the porthole 8as shown thus far. To have the handle 15, 15a mounted in the various prefixed positions disclosed in connection with FIGS. 3-8, however, two different outer frames 30 for a same handle 15 as shown in FIGS. 3-6 have to be manufactured, four different outer frames 30 for an always ergonomic handle 15, 15a as shown in FIGS. 3, 4, 7, 8. However, a handle 15, 15a made one piece with the outer frame 30, such as co-molded therewith, is very strong, inexpensive and neat.

(81) In order to avoid having to manufacture and store different outer frames 30 with one piece handle 15, 15a, it is also possible to provide for a modified outer frame 30a and a detachable handle 15b, as shown in FIG. 14-16. FIG. 16 is schematic, and does not show several details as shown in FIGS. 9-11.

(82) Besides the possibility of changing the position of the handle, this would also bring about other advantages, such as the possibility of easily changing the layout of the handle for different models of laundry machine 1 without having to provide different molds of the entire outer frame.

(83) Outer frame 30a corresponds to the outer frame 30 already disclosed apart from what disclosed below.

(84) Handle 15b advantageously includes a body portion 16b similar to body portion 16 of handle 15, advantageously including a zone 22b having a comparatively large radial extent and a zone 23b having a comparatively small radial extent, as well as a wall 52b extending along part of a cylindrical surface and lateral walls 54b one piece therewith, similar to walls 52, 54 just described. Wall 52b crosses body portion 16b at an intermediate zone thereof. The generally flat body portion 16b includes an arc of circumference edge 17b and a free edge 18b having the shape described above. The other parts of handle 15b are labeled similarly to the corresponding parts of handle 15, with a b suffix.

(85) From the wall 52b extending along part of a cylindrical surface, a pair of bushings 59 advantageously protrudes, preferably generally radially, outwards, but extending parallel to each other and parallel to a median radial plane of the handle 15b. In the mounted condition of the handle 15b, the bushings 59 advantageously insert into bushings 60 having holes 61 that extend from the beveled inner circumferential edge 34a of outer frame 30a. Bushings 60 also advantageously protrude preferably generally radially outwards, but extending parallel to each other and parallel to a median radial plane defined centrally of the two bushings 60. Screws 62 or bolts advantageously retain the handle 15b to the outer frame 30a by passing through holes 61 and engaging bushings 59.

(86) Outer frame 30a may include two or four series of holed bushings 60 as shown in FIGS. 14, 16 for mounting the handle 15b (or a handle having a mirror-image shape similar to that shown in FIGS. 7, 8).

(87) The holes 61 that are not used for mounting the handle 15b may be advantageously covered with a cap. Alternatively, all the holes 61 may be covered by a thin membrane having a preferential rupture circumference, and during installation of the laundry machine 1, the membrane is removed only at the two holes 61 being actually used for mounting the handle 15b.

(88) In the handles 15, 15a, 15b, the free edge 18, 18a, 18b of the body portion 16, 16a, 16b can have a thickening 58, 58b, preferably rounded, on the inner side of the handles 15, 15a, 15b.

(89) The handle of the porthole can also be fixed, instead of with screws and threaded holes as just described, with snap action pins, or any other suitable system, in particular suitable coupling element(s) and matching coupling element(s).

(90) With reference to FIG. 17, shoving a different advantageous embodiment of the invention, the position of the handle 15c may also be changed through a rotation of an annular handle support 63 to which handle 15c is fixed (for example handle 15c and annular handle support 63 may be a single body or one piece); in this case annular handle support 63 is advantageously sandwiched between the outer and inner frames 30, 30a, 31, and it is arranged in such a way that it can be mounted in at least two different angular positions with respect to outer frame 30, so that handle 15c is positionable in at least two prefixed positions by mounting annular handle support 63 in one of these at least two different angular positions. The other parts of handle 15c are labeled similarly to the corresponding parts of handle 15, with a c suffix.

(91) Thus, the grip-only handle 15b, 15c is configured to be alternatively positionable in one of at least two prefixed positions with respect to the frame(s) 30, 30a, 31.

(92) Moreover, said at least two prefixed positions are such that in any one of these prefixed positions, said grip-only handle 15b, 15c, when the porthole 8 is closed, has a different angular position with respect to the rotation axis RR.

(93) Preferably, the prefixed positions of the grip-only handle 15b, 15c correspond to those described above with reference to grip-only handles 15, 15a.

(94) The porthole can comprise only a single frame and a glass suitably fixed thereto, or even no glass and be one transparent or non-transparent part, being more properly called a door in the latter case.

(95) The various disclosed features may be present individually or in any combination in a laundry machine according to aspects of the invention.
