Description

The invention relates to a loading door of a dishwasher according to the preamble of claim 1.

Such a loading door is out of the DE 9 413 641 U1 known.

It is known to equip dishwashers with a horizontally pivotable loading door. The pivoting of the loading door takes place at a lying in the region of the lower edge of the loading door pivot axis. For closing the loading door, a door lock is provided on the opposite side of the pivot axis of the loading door. The door lock falls automatically when closing the loading door in the closed position. To open the loading door, a manual intervention is required. For this purpose, the dishwasher comprises an unlocking mechanism in the region of the door lock, which is accessible via a cover carrier arranged on the upper edge of the loading door. The cover support has in the center a handle shell, in which an unlocking flap acting on the door lock is accommodated. The grip serves essentially as protection against Berühungen of electrical cables and components that are arranged in the diaphragm support for setting a work program, or to a display of the program flow. It is also known to carry out the handle shell in two pieces. The grip comprises a fixedly connected to the diaphragm support, in particular molded handle shell base, and a separate Grip cover. The handle shell cover can be coupled by means of various connection techniques on the diaphragm support and / or on the handle shell base. The coupling of the handle shell cover to the handle shell lower part and / or the diaphragm support is known to pivot by the handle shell cover eg laterally at least one provided bolt in each case a bearing which is mounted on the handle shell lower part and / or diaphragm support engages. The pivoting of the handle shell cover takes place between two abutment positions about the pivot axis which passes through the centers of the cylindrically shaped, symmetrical to the center line of the handle shell cover opposite pins. A first stop position corresponds to a pivoting position in which the unlocking mechanism of the door lock has been operated in any case and thereby the door lock has been opened. A second stop position corresponds to a rest position, which is taken as long as no pivoting of the handle shell cover, ie no manual intervention takes place in this. On the side guide system of the handle shell cover and the handle shell lower metal springs are also provided to reset the handle shell cover from the pivoting position to the rest position.

It is an object of the invention to provide a loading door of a dishwasher according to the preamble of claim 1, wherein the return mechanism of the handle shell cover is particularly simple and inexpensive.

The object is achieved in such a loading door of a dishwasher by the characterizing feature of claim 1.

The loading door according to the invention of a dishwasher has a door lock for closing a loading door, which can be unlocked by a manual intervention in a handle shell from the closed position. This grip is arranged on a diaphragm support, which is arranged on a particular overhead part of the Beschikkungstüre. In this case, the grip shell comprises a handle shell base part which is fixedly connected to the diaphragm support, preferably a molded-on grip shell, and a separate handle shell cover which pivotably connects to the diaphragm support and / or grip shell base. The Griffschalendekkel can be pivoted by manual intervention by a certain angle about its pivot axis from its rest position to a pivoting position. Further, at least one spring element is arranged on the handle shell cover, which takes over the function to reset the handle shell cover from the pivot position to the rest position as soon as the handle shell cover is released during pivoting or after reaching the pivot position. According to the handle shell cover and spring are made in one piece.

In a preferred embodiment, the spring element is designed as a leaf spring. In a particularly preferred, because inexpensive, embodiment of the invention, the handle shell cover is injection-molded with the leaf spring in one piece of plastic. This not only reduces the material costs, but also the assembly costs, since formerly necessary assembly step, namely the attachment and biasing of the metal springs, is eliminated.

In another embodiment, the handle shell detent is formed with the spring also in one piece, however, e.g. by special design of the injection molds, different combinations of materials for the spring and / or other parts of the handle shell cover, and / or the handle shell lower part, and / or the diaphragm carrier used. Another advantage of the invention is thus that the overall picture of the properties of the spring can be changed by a material modification, while the one-piece and cost-effective production of spring and handle shell cover is retained. Without further explanation and without limiting the invention, it is conceivable that the spring can also be formed on the handle shell lower part and / or diaphragm support.

The invention is explained in more detail below with reference to the drawings of an embodiment.

A household dishwasher 1, after Fig. 1 essentially comprises a device base 2 and a cover plate 3. Within a washing compartment 4 items to be washed can be arranged for the purpose of cleaning.

The washing compartment 4 is accessible by pivoting a loading door 5 from a closed vertical orientation to an open horizontal position. The loading door comprises an operator door facing outer door panel 6 and an inner door panel 7 which forms an inner side wall of the flushing container when the door is closed. Inner and outer door panel (6, 7) are coupled together by a plurality of screw connections. In the closed position of the loading door · above the outer door panel, a cover carrier 8 is attached, which includes not shown operating or adjusting elements for setting a wash program. The panel support 8 is open when not installed on its rear side and is covered during installation by an upper portion of the inner door panel 7. To attach the panel carrier to the outer door panel 6 connecting pin not shown are arranged on the panel support 8. The diaphragm support 8 is joined to the inner door panel 7 by a plurality of screw connections, for which 8 not shown Schraubköcher are provided on the diaphragm support. For coupling the aforementioned operating or adjusting elements not shown Schraubköcher and latching hooks are still provided.

The diaphragm carrier 8 has centrally arranged in Fig. 2 illustrated grip shell 9, which serves to engage a manual operation of a door lock. The grip 9 is made in two parts and consists essentially from a handle shell lower part 10 and a handle shell cover 11. The handle shell lower part 10 is formed integrally with the diaphragm support 8, that is, it is integrally formed on this. The handle shell cover 11 is designed separately and pivotally coupled to the handle shell lower part 10. In order to guide the pivoting movement without lateral play safely and easily a groove in the handle shell lower part 10 and thus provided in the diaphragm support 8, in which engages the handle shell cover. In this case, geometry of handle shell lower part 10, handle shell cover 11 and guide groove are designed so that in each position of the handle shell cover 11 during pivotal movement into the space behind the diaphragm support 8 can not intervene, the manual intervention in the handle shell 9 to perform the pivoting movement in the direction of the arrow 9a.

For the realization of the pivotal connection of the handle shell lower part 10 on the handle shell cover 11 are on the diaphragm support and the handle shell lower part 11, two bearings 12, of which in Fig. 2 only one is visible, provided, each one on the handle shell cover 11 integrally formed bolts 13, of which in Fig. 2 only one is visible, record. The bolts 13 are located in each case on the end piece of a guide web 14, which is integrally formed on both sides of the handle shell cover 11. Above the pin 13 is in each case on the guide webs 14 of the handle shell cover 11 depending on a spring element 15 in the form of a leaf spring, from the in Fig. 2 only one is visible, integrally formed. Bolt 13, bearing 12, guide webs 14, leaf springs 15 are each symmetrical to the imaginary vertical center line of the handle shell 9 opposite each other. From the handle shell lid 11 from the guide webs 14 taper to the respective clamping point 16 of the leaf-spring-like spring element 15 and then extend with approximately the same width up to their end pieces, which each receive a pin 13. The clamping points 16, of which in Fig. 2 only one is visible, which are formed on the guide webs 14 leaf spring-like spring elements 15 are respectively on the front side of its guide web 14. The leaf spring-like spring elements 15 each have a bend which the direction of movement of their leaf spring legs 17, of which Fig. 2 only one is shown, in the direction of pivotal movement, indicated by arrow 18 changes. The leaf spring legs 17 are spaced from their guide web 14, more precisely whose end face, due to the bend, while the resultant spring travel is adequately sized according to the applied restoring force and further ensures that the spring elements 15 a smooth pivoting of the handle shell cover 11 from Do not hinder the rest position in the swinging position. Moreover, all other and thus the entire design parameters of the spring elements 15 are designed so that the restoring forces of the spring elements 15 in any case sufficient to return the handle shell cover 11 from the pivoting position to the rest position.

In order to adequately dimension the restoring spring elements 15 not only with regard to their function but also functional reliability and service life, it may be expedient to modify the overall behavior of the spring elements 15 by adaptations in the material. Therefore, another embodiment not shown in the drawing is shown directed, the spring elements 15 while also integrally with the handle shell cover 11 and / or handle shell lower part 10 and / or diaphragm support 8 executed, but a mix of materials, for example made of different plastics or a plastic with different reinforcing and / or auxiliaries and / or additives optionally below Addition of conventional stabilizers allowed, for example, can arise when the injection molding tool is designed so that different modified plastics are supplied via different channels.
