Description
- This invention relates to a hinge for doors of domestic appliances.
- More specifically, this invention relates to a hinge for doors of dishwashers.
-
- In the field of electrical domestic appliances, and, therefore, also dishwashers, there has been an unstoppable effort during recent years towards achieving increasingly higher energy efficiency classes.
- In other words, the aim is to improve the energy efficiency of the electrical domestic appliances, basically by a reduction in energy consumption.
- In the specific case of dishwashers, the reduction in energy consumption is obviously linked with the reduction of the temperature of the washing water and also the temperature for drying the washed dishes.
- In effect, it is the heating devices, consisting basically of electrical resistors, which determine the high level of electricity absorption during the step for washing dishes.
- Whilst the lower temperature of the water can be compensated effectively, in terms of both operating and energy efficiency, by means of a longer washing cycle or a greater effectiveness of the jets, in contrast, with regard to the drying of the dishes, its is difficult to compensate for the reduced temperature of the drying air.
- The consequence of such a reduction in temperature would therefore be that at the end of the cycle the dishes would no longer be as dry as they would be with traditional washes.
- In order to overcome such a poor drying efficiency, some manufacturers have considered causing, at the end washing cycle, a circulation of air which is able to at least partly compensate for the lack of a heated flow of air.
- The most practical system is without doubt to open the door at the end of the washing cycle, when the dishes are still hot, in such a way as to facilitate final drying, circulating air in the dishwasher which is drier than that which is present.
- For this purpose, some manufacturers have made opening systems equipped with motor-driven hinges and devices, which can be activated by the dishwasher's electronic unit and which is able to cause a partial opening of the door.

EP 919 776 Document EP 2 284 344 discloses a hinge for doors of electrical household appliances comprising a damper. - These systems, although effective, are not free from drawbacks.
- A first drawback connected to the use of the motor-driven systems and devices described above is due to their high cost.
- Further drawbacks of the prior art systems are the complexity of installation and their difficult maintenance.
- The aim of the present invention is, therefore, to overcome the disadvantages indicated above and provide an alternative to the prior art devices described above.
- Another aim of this invention is to provide a hinge for doors of dishwashers which is inexpensive to manufacture, efficient to operate and easy to maintain.
- This invention accordingly provides a hinge for doors or wings comprising the features described in any of the appended claims.
- The technical features of the invention, with reference to the above aims, can be easily inferred from the appended claims, in particular claim 1, and preferably any of the claims that depend, either directly or indirectly, on claim 1.
- The advantages of the invention are more apparent from the detailed description which follows, with reference to the accompanying drawings which illustrate a preferred, non-limiting example embodiment of the invention and in which:
-
Figure 1 is a schematic side elevation view of a preferred embodiment of a hinge according to this invention; -
Figures 2 to 4 are respective schematic side elevation views of the hinge ofFigure 1 in three different configurations of use. - With reference to
Figure 1 , the reference numeral 1 denotes in its entirety a preferred embodiment of the hinge according to this invention. - The hinge 1, paired with another one, is designed to be mounted, on a dishwasher, not illustrated, to connect the frame to a door in such a way that the latter is movable relative to the frame between a closed position and an open position.
- With reference to the accompanying drawings, the hinge 1 comprises a
first element 2 adapted for fixing to the above-mentioned, not illustrated, door of the dishwasher, and asecond element 3, at least in part of a box-shaped type, adapted for fixing to the above-mentioned, not illustrated, frame of the dishwasher. - The
first element 2 is pivoted to thesecond element 3 by apin 4 to allow reciprocal rotation of theelements - The axis of rotation A1 defines the axis of rotation of the above-mentioned, not illustrated, door relative to the above-mentioned frame, also not illustrated.
- The first and
second elements lever 5. - At a first end of it 5a, the connecting
lever 5 is pivoted to thefirst element 2 by apin 6 in such a way as to rotate at least partly relative to thefirst element 2 itself about a respective axis A2. - The hinge 1 also comprises a
helical spring 7 and adrive rod 8 of thespring 7, both supported by the second, box-shaped element 3. - The
drive rod 8 is engaged at the bottom by ahook 9. - The
hook 9 is pivoted on thelever 5 at itssecond end 5b, opposite the above-mentionedfirst end 5a. - The
drive rod 8 of thespring 7 is advantageously positioned inside thespring 7 itself and is connected to the top thereof, for example by astop element 7a in such a way as to compress it, according to substantially known methods. - In other words, the
drive rod 8 has an upper end that is longitudinally opposite the end that is hooked to thelever 5, the upper end being designed to engage an upper end coil of thespring 7 in such a way as to compress thespring 7. - The
spring 7 and therod 8 extend principally along a direction of extension B of thesecond element 3. - The
spring 7 constitutes first elastic means for the hinge 1. - The second, box-
shaped element 3 has abracket 10 with a flat extension perpendicular to the plane of the figures, ahole 11 being made on thebracket 10 for the passage of thedrive rod 8. - At the
hole 11, and coaxial with it, atapered friction element 12 is housed. Thefriction element 12, of substantially known type, comprises an uppertapered portion 12a and a lowercylindrical portion 12b inserted in thehole 11. - On the upper
tapered portion 12a acylindrical collar 13 is fitted, on an upper edge of which the bottom end of thespring 7 rests. - The tapered
upper portion 12a is divided into two lateral fingernail-shaped protrusions adapted to superficially engage, and apply a frictional action on, the twoopposite faces rod 8. - A
slot 14 is made on thelever 5. - The
slot 14 with its peripheral edge slidably engages with aguide pin 15, integral with thesecond element 3. - The
slot 14 defines a first cam made on thelever 5. - The hinge 1 also comprises a
rocker 16 pivoted on thesecond element 3 so as to oscillate about a respective axis A3. - The
rocker 16 comprises afirst portion 16a engaged with ahelical spring 17 and asecond portion 16b designed to engage with thelever 5, as illustrated inFigures 1 to 3 . - The
helical spring 17 is stably interposed between the above-mentionedfirst portion 16a of the rocker and aprojection 18 protruding from abottom wall 3a of thesecond element 3. - A
pin 19, also projecting from thebottom wall 3a, defines an end of stroke stop element for therocker 16 in its oscillation about the axis A3. - The
rocker 16 defines, for the hinge 1, pushing means designed to determine, as will be described more fully below, the relative moving away from the above-mentioned first andsecond element - The
helical spring 17 defines, for the hinge 1, second elastic means designed to activate therocker 16. - With reference to the accompanying drawings, the
lever 5 has, in the proximity of itsend 5b, asecond cam 20. - As illustrated in
Figures 1 to 3 , thesecond cam 20 is designed to engage with thesecond portion 16b of therocker 16. - More specifically, at its
second portion 16b, therocker 16 comprises aroller 21 defining the follower in the coupling with thesecond cam 20. - In use, in the configuration illustrated in
Figure 1 which shows a closed condition of the above-mentioned and not illustrated door of the dishwasher corresponding to a condition of minimum distance between the first andsecond element spring 17 is in a preloaded condition. The maintaining of the stable closing configuration of the dishwasher door is ensured by a suitable closing hook of substantially known type and not illustrated, advantageously of the electro-mechanical type. - For this reason, in the configuration illustrated in
Figure 1 , therocker 16, through theroller 21, applies on the connecting lever a force F, generated by the compression of thehelical spring 17. - When, using, for example, a command and control unit of the dishwasher, the above-mentioned and not illustrated hook for closing the door is disengaged, the force F pushes, using the connecting
lever 5, thefirst element 2 and, consequently, the door, not illustrated, which is integral with it, to adopt an open configuration, illustrated inFigure 2 . - As clearly illustrated in
Figure 1 , thesecond cam 20 made on thelever 5 has aprotrusion 20a such as to form a stop zone for the follower consisting of theroller 21. - The
second cam 20, in particular with theprotrusion 20a of its profile, in conjunction with thefollower 21, defines means for limiting the opening of the door, the limiting means being designed to brake the relative moving away of the first andsecond element Figure 2 . The above-mentioned limiting means also comprise thepin 19 designed to define an end of stroke stop position for therocker 16. - Advantageously, the partial opening of the door determined by the above-mentioned limiting means is defined by a mutual angle of opening between the first and the second element, of between 5 and 15 sexagesimal degrees.
- Still more advantageously, the partial opening of the door is defined by a mutual angle of opening between the first and second element, of between 8 and 10 sexagesimal degrees.
- In the preferred embodiment illustrated in the accompanying drawings, the above-mentioned partial opening is defined by an angle of approximately 8 sexagesimal degrees.
- In practice, the elastic force F determined by the preloading of the spring and applied to the door of the dishwasher to determine a partial opening is able to generate a flow of air inside the dishwasher. The circulation of air facilitates the drying of the dishes which have just been washed.
- Starting from the open configuration partly illustrated in
Figure 2 , a force by the user is needed to proceed to a greater opening of the door. In other words, after overcoming the obstacle consisting of the above-mentionedprotrusion 20a of the profile of thesecond cam 20, a resistance which is advantageously overcome with approximately 7° of opening (in the case illustrated, that is, up to approximately 15°), therocker 16 remains disengaged from the connectinglever 5, with the relativefirst portion 16a pushing into contact with thepin 19 of thehelical spring 17. -
Figure 3 shows the position of last contact of thefollower 21 with thesecond cam 20 of thelever 5. -
Figure 4 illustrates a configuration of the hinge 1, corresponding to a fully open position of the door of the dishwasher, with the first andsecond element - Between the position illustrated in
Figure 3 and that inFigure 4 , that is, between approximately 15° and approximately 90°, the pushing element defined by therocker 16 is disengaged. - During the closing movement of the door, in particular during the passage from the open configuration partly illustrated in
Figure 2 to the configuration illustrated inFigure 1 , the action exerted by the user causes the loading of thespring 17. In effect, when thesecond element 3 moves towards thefirst element 2, the connectinglever 5 applies, with thesecond cam 20, a thrust action on thefollower roller 21 and, through therocker 16, causes the squashing of thesecond spring 17. The action of the above mentioned, and not illustrated, hook for closing the door maintains the preloading condition of thesecond spring 17 until the dishwasher door is closed. In this condition, the pushing means is ready to act for the next opening of the door, in the manner described above. - With reference to the connecting
lever 5, during its movement relative to the second, box-shapedelement 3, theupper end 5b of thelever 5 remains substantially equidistant from thewall 3b of thesecond element 3, parallel torod 8. This guarantees that during its sliding relative to the second, box-shapedelement 3 thedrive rod 8 remains parallel to itself and is basically translated along the direction B. - The fact that the
rod 8 is translated along the direction B, that is to say, without making an angle with that direction, means that the frictional action applied to it by the taperedfriction element 12 is constant and regular. - In other words, thanks to the presence of the
cam 14 and therelative guide pin 15, therod 8 remains with itsfaces rod 8 moved at an angle in such a way as, for example, to strike one of the fingernail-shaped protrusions on thefriction element 12. - Advantageously, so as not to dissipate, due to the friction, the elastic energy which accumulated by the
spring 17 and intended for pushing of the door when opening, therod 8 has, at its lower zone close to thehook 9, a reduced thickness relative to that of the remaining part. - In other words, thanks to the thinning, not illustrated, of the
rod 8 in its lower zone, thefaces rod 8 do not enter into contact with theelement 11 during the pushing exerted by therocker 16. - In that way, the frictional action of the hinge is achieved for the entire opening-closing stroke with the exception of the first stretch, that is to say, for example with reference to the preferred embodiment illustrated, between 0° and 8°.
- The hinge 1 according to this invention offers many obvious advantages. A first advantage is due to the simple and inexpensive construction which enables the door to be provided with the opening force without any electric drive unit.
- Another advantage is its compact and easy construction.
- The hinge 1 according to this invention achieves the preset aims, providing an effective, practical and inexpensive alternative to the prior art devices.
- The invention described has evident industrial applications and can be modified and adapted in several ways without thereby departing from the scope of the inventive concept. Moreover, all the details of the invention may be substituted for technically equivalent elements.
