Definitions
- the invention is in the field of equipment and machines which are used for treating, in particular for drying and / or washing, laundry or other objects and which are generally referred to below as laundry treatment machines.
- the invention relates to a method for producing a loading door for a laundry treatment machine with a door frame and an insert held in the door frame, wherein the door frame is formed at least by joining at least one frame inner part with at least one frame outer part, and the insert between the frame inner part and the Frame outer part is introduced such that it is supported with at least one support surface on a plurality of door frame side support areas.
- the invention further relates to a loading door for a laundry treatment machine having a door frame which comprises at least one frame inner part and a frame outer part, and with an insert arranged in the door frame, which abuts at least in sections on contact areas of the door frame.
- a door frame which comprises at least one frame inner part and at least one outer frame part joined thereto. Between the frame parts, an insert is held and introduced in such a way that it is supported with at least one support surface on a plurality of door frame side support areas.
- the insert is a preferably pot-shaped glass pane (sight glass), the edge of which is received in a circumferential gap or receiving space formed by the frame parts.
- the receiving space is sized so that sufficient clearance is available to production-related deviations in the actual measure of Thickness of the glass to balance safely.
- a seal is arranged between the frame inner part and the glass pane, which ensures a secure seal by its elasticity and its cross section and also compensates for said production tolerances of the insert by a more or less strong axial compression.
- the actual thickness of the door frame may vary by design if the elasticity of the seal is insufficient to completely compensate for any dimensional deviations of the insert thickness.
- an object of the present invention is to specify a method for producing a loading door or in the creation of a loading door, is provided by or in which a tolerance compensation of the insert dimensions such that the thickness of the loading door always in a predetermined Target dimension is adjustable and thus design specifications can be met to the effect that, for example, the frame inner part and the frame outer part at predetermined edges without joints and gap lie on each other.
- At least the support areas are made of a material which is brought into a temporarily plastically deformable state prior to joining the frame parts, forces are applied to the bearing areas with inserted insert, so that they are so on the Adjust the geometry of the insert so that a specified target dimension of the door thickness is set, and then the support areas are brought back to a non-deformable (solid) state.
- a first significant advantage of the invention is thus that as well comparatively large tolerances can be accepted, in particular, in the dimensions of the insert that are relevant for the loading door thickness, because these are compensated for individually by displacement, erosion or deformation of the material of the door frame-side support areas. This also has a positive effect on the production costs because higher tolerances in the actual thickness of the insert are acceptable as a result.
- the inventive method is also characterized by a simple feasibility and automation, because advantageously at the same time applied to the forces exerted on the door frame parts on these forces can also serve for deformation or shape adaptation / Vertikalwashanpassung the support areas.
- the bearing areas After the bearing areas have again been brought into a substantially non-deformable or solid state-for example, a hardened or solidified state-they can reliably exert their supporting and holding functions in a geometry optimally adapted to the shape of the bearing surface of the insert.
- a method of manufacturing a loading door which meets even the most demanding specifications regarding the gauge size of the loading door and the design specifications - e.g. a gapless joining the door frame parts in the externally visible area (for example, on the door frame surface area) - is sufficient.
- the insert is brought into a prestressed position which is withdrawn with respect to the support areas during the joining and is released again after completion of the joining.
- a pre-stress is exerted on the seal which is normally provided between inserts such as sight glasses and a frame part, thus producing a tight fit between the insert and the respective support area.
- the insert (sight glass) can be detected by a suction cup and drawn in the direction of biasing.
- the inventive temporary plastic deformability of at least the bearing areas can basically be realized by various physical and / or chemical methods.
- a dissolving or softening of the support areas by a solvent or by (thermal) energy supply is conceivable.
- the bearing areas or particularly preferably the frame inner part and the frame outer part are made of a thermoplastic material.
- these can preferably be provided with cooperating connecting webs, which are heated together with the support areas and plastically deformed or connected.
- a so-called heating mirror between the joining partners (frame inner part and frame outer part) can be positioned, so that the thermoplastic material melts due to the heat energy thus supplied. Then, the heating mirror is removed and the frame parts are placed on each other (joined) such that the cooperating connecting webs merge with each other.
- the respective support region is adapted to the geometry of the insert or the support surface such that excess material is displaced.
- the loading door manufacturing technology can be particularly elegant and expedient brought to a predetermined target thickness.
- the above-mentioned loading door is designed so that at least the bearing areas consist of a temporarily plastically deformable material and the bearing areas are plastically shaped by the joining of the frame parts, that sets a predetermined target dimension of the door thickness while compensating for component tolerances of the insert.
- the existing of a temporarily plastically deformable material support areas allow by inserting the insert and the joining a simple optimized adjustment, so that adjusts the predetermined target amount of door thickness.
- frame inner part and frame outer part preferably made of a thermoplastic material and have cooperating connecting webs.
- the insert may be a glass pane or a so-called sight glass, which may be made, for example, in a conventional manner from a preferably transparent plastic or silicate.
- the advantages of the invention are also realized and / or preferred in the case of an (additional further) insert which comprises an element extending to the inside of the door, such as a signal transmitter or a locking element.
- FIG. 1 fragmentary main components of a loading door before the
- FIG. 2 shows a frame outer part of a loading door
- FIG. 3 shows a section of a loading door in the assembled state corresponding to FIG. 1,
- FIG. 4 details of a detail A of a frame outer part from FIG.
- Figure 5 shows a sectional view of a portion of the detail of Figure 4 with an inserted insert.
- FIG. 1 shows a fragmentary sectional view of essential elements of a loading door 1 according to the invention prior to their final assembly or joining.
- the loading door 1 comprises a door frame 2 which is formed by at least one frame inner part 3 and a frame outer part 4 (not yet joined in FIG. 1). Between the frame parts 3, 4, an insert 6 is arranged in the form of a sight glass 7 already inserted into the frame inner part 3, which is held after the joining between the frame parts.
- the sight glass 7 has a circumferential edge 8, which comprises a door frame inside bearing surface 9 and a door frame outer side bearing surface 10.
- the sight glass 7 is located on a previously applied to a circumferential ridge 12 or rolled-up seal 14, which provides with an inside sealing lip 15 in a conventional manner for a sealing closure of a feed opening, not shown, a laundry treatment machine through the loading door 1.
- the support surface 10 is supported in the mounted state of the loading door a plurality of doorframe side support portions 20 from, of which in Figure 1, only a support portion of a substantially radially extending rib or a web 21 is shown.
- At least the support regions 20 are made of a material 22 which is temporarily plastically deformable.
- both the frame inner part 3 and the frame outer part 4 are made of a thermoplastic material.
- At least the supporting regions 20 are brought into a temporarily plastically deformable state, for example by introducing heat.
- the insert 6 is inserted into the frame inner part 3, between the frame parts 3, 4 a so-called (not shown in FIG.
- heating mirror is introduced, which due to its adapted geometry specifically heats the regions of the frame parts 3, 4 to be softened .
- the sight glass 7 is gripped at its curvature by a suction cup, not shown, and pulled in the direction of arrow 24 vertically downwards. Due to the elastic deformation of the seal 14, the insert 6 (sight glass 7) is thus in a prestressed position, which has a somewhat decreasing effect on the material removal or on the material displacement in the region of the support regions 20.
- the frame parts are preferably joined by thermoplastic fusion of connecting webs (as shown in more detail below in connection with FIG. 3) and connected as shown in FIG. As can be seen from FIG.
- the rib 21 forms a strong and highly resilient support for the sight glass 7.
- the door seal 14 resiliently against the direction of the arrow 24 elastically rebounds again, resulting in a tight interference fit between support surface 10 and the corresponding cooperating contact surface 25 of the support area 20 leads.
- Figure 3 shows to further illustrate the joining principle and the adjustment of the nominal size of the door thickness in a perspective view of the insert 6 (Figure 1) facing structure of the frame outer part 4. It can be seen more distributed over the circumference holding or support webs 21, of which represent a support web 21 has been described in detail in connection with FIGS. 1 and 2.
- the other support webs are adjusted at their support areas 20 in a corresponding manner to the individual geometry and tolerant thickness of the (not shown in Figure 3) use by melting. It also recognizes a substantially circumferential, corrugated connecting web 30 and a further connecting web 31, which cooperate with correspondingly formed and complementarily positioned connecting webs of the frame inner part 3 when joining the frame parts.
- FIG. 4 shows, in an approximately radial view, enlarged area A from FIG. 3.
- a centering post 40 and posts 41, 42 arranged on both sides are shown with an approximately cross-shaped cross section and with support areas 43, 44 formed at their respective free ends.
- 44 is a bearing surface of a functional insert, such as a transducer pin, fixed and stored by means of a frame inner part.
- FIG. 5 shows in a sectional view with an attached insert 50
- the centering post 40 penetrates a corresponding receiving bore 52 of a door frame inner part 54 which, as shown in this exemplary embodiment, can be formed integrally with the insert 50.
- On the inside bearing surfaces 55, 56 of the insert 50 are based on the support areas 43, 44, which made in a corresponding manner by previously done heating the material of the posts 41, 42 temporarily plastically deformable have been prepared and so to a tolerance compensating removal or displacement of the material.
