Definitions
- This invention relates to a washing machine door hinge made of plastic-based material.
- the invention more particularly relates to a plastic-based washing machine door hinge having ribbed components to enhance mechanical strength thereof and the hinge comprising various recesses for providing smooth water flow pattern in the vicinity of the washing machine door.
- the present invention concerns a washing machine door hinge of the kind comprising a body immovably secured to the door housing frame and at least one arm integrated to the body.
- a washing machine door hinge is known from the background art.
- Known washing machine hinges are metal based and having in particular zamac body and arms (zinc aluminum metal alloy casting).
- metal density is much higher than plastic materials, for instance zinc having 7,049 g/cc, aluminum having 2,77 g/cc whereas polyurethane having 1 g/cc and High Density Polyethylene (HDPE) having 0,95 g/cc, mounting such a metal- based hinge to the washing machine inevitably increases the overall weight of the machine.
- HDPE High Density Polyethylene
- a washing machine hinge As a washing machine hinge is partially in contact with water in the washing machine, a m etal-based h inge i s u navoidably reacted to the water, a ctually the water is a mixture of a chemical fluid due to presence of detergent and other softening agents in the water. This would lead to vulnerability of the hinge in the presence of the corrosive effects.
- washing machine hinges In practice, most critical parts, in the sense of mechanical tension, of washing machine hinges are the arms coupled to the body. As the hinge is exerted bending moment in typical working conditions, shear and in more immediate concern normal stresses take place in the sections of the hinge arms.
- Known washing machine hinge arms are so formed to exhibit sufficient strength to prevent failure of the arms under the external forces and bending moments. However, providing sufficient strength to such external forces are performed through increasing section thickness which leads to both material loss and weight increase of the hinge.
- the invention seeks to provide a washing machine door hinge rendering sufficient strength against external forces and simultaneously decreasing overall weight of the washing machine.
- this object is accomplished in a washing machine of above kind in that the hinge is embodied by plastic injection molding and in that the arms having ribbed structure.
- the washing machine hinge according to the present invention further comprises that the body has a ribbed structure and optionally bent i.e. having a certain radius to adapt door housing frame.
- the hinge according to invention further comprises channels through which holes embodied to secure the body to the frame. DESCRIPTION OF THE FIGURES
- FIG 1 illustrates washing machine door assembly by the hinge according to the present invention.
- Figure 2a illustrates the hinge from perspective right view according to the present invention.
- Figure 2b illustrates the hinge from perspective left view according to the present invention.
- Figure 2c illustrates the hinge from perspective rear s ide view a ccording to the present invention.
- Figure 3a illustrates the hinge arm in perspective view according to the present invention.
- Figure 3b illustrates the hinge body securing housing in perspective view according to the present invention.
- Figure 3c illustrates the hinge body securing housing in perspective view according to the present invention.
- FIG. 1 illustrates washing machine door assembly by the hinge according to the present invention.
- the hinge is placed between the washing machine d oor ( 15) a nd the front s heet ( 14) of the machine.
- hinge body (16) is secured to door housing frame and hinge arms (8) - at least one arm - are secured to the door.
- FIG. 2a illustrates the hinge from perspective right view according to the present invention.
- the hinge comprises arms (8) integrated to the body (16) and the hinge is embodied by plastic injection moulding, so defining a plastic-based washing machine door hinge.
- the arms (8) comprise a ribbed structure (1 ) to strengthen thereof against external forces and bending moments in particular.
- outer faces of the arms (8) are moulded in a closed-form structure unlike the inner faces having ribbed structure.
- the outer faces can have a ribbed structure optionally.
- Figure 2c illustrates the hinge from perspective rear s ide v iew a ccording to the present invention.
- the body (16) of the hinge optionally, can have ribbed structure (12) for both strengthening the hinge and decreasing the weight of the hinge.
- seats (9) - At the rear face of the body (16), seats (9) - at least one seat - are provided in the vicinity of the two ends.
- the seats (9) are foreseen for distributing the local stresses induced by attachment means, like screws, when the body (16) is secured to the housing frame.
- Two protrusions (10) are embodied at the rear side of the body (16) for facilitating the body to arrange to the housing frame.
- plurality of apertures (11 ,13) are formed to ease extracting the protrusions (10) from the mould.
- the apertures (11 ,13) provides that the cross section of the body (16) remains even, through the longitudinal direction of the body (16), in the presence of the ribbed structure. Otherwise, uneven cross section would lead to stress propagation at the section transitions.
- the arm (8) has an external radius (2) at the corner region thereof and an internal radius (3) for preventing stress propagations that are induced by the external forces.
- Bosses (4) are placed at the two ends of the body (16), the bosses (4) are engaged to corresponding housings in the door (15).
- the body (16) includes channels (17) at both ends, and the channels (17) comprise holes (5) through which securing means, like bolts, screws etc, are introduced for connecting the body (16) to the housing frame.
- securing means like bolts, screws etc.
- relatively short bolt can be utilized for connecting the body (16) to the sheet of the machine. So, bending moments that would be induced by external forces can be decreased by the decreasing bolt length.
- connection radiuses are formed to smoothen section transitions, so minimizing stress propagations at the connection points.
- radiuses (6) can be formed optionally.
