DESCRIPTION

CUTLERY BASKET AND BASKET SET FOR A DISHWASHING MACHINE COMPRISING QUICK ACCESS ZONE

The present invention relates to a cutlery basket for storing small to medium sized cutlery and to a basket set comprising a dishwasher basket and at least one cutlery basket.

In a conventional dishwashing machine cutlery is stored in a cutlery basket arranged on the lower basket of the dishwashing machine or on a separate tray formed as top drawer of the dishwashing machine. Delicate glassware is stored on glass supports at the sides of the upper basket. When loading cutlery, dishes and glassware into the dishwashing machine, the individual parts are sorted and placed at the convenient positions or compartments of the dishwashing machine.

It is an object of the invention to provide a cutlery basket for a dishwasher basket and a basket set, comprising a dishwasher basket and at least one cutlery basket, which provide a conventional dishwashing machine with a quick access loading zone .

The invention is defined in claims 1, 13 and 29, respectively.

Particular embodiments are set out in the dependent claims.

In everyday loading processes for loading cutlery and dishes into a dishwashing machine the user needs some time to sort the cutlery and dishes and to place them at the appropriate location on the upper or lower basket. For example the cutlery is placed in the cutlery basket on the lower basket, glasses are placed on specific glass supports at the sides of the upper basket, and small and large plates are inserted in the corresponding plate inserts in the lower or upper basket. This is alright, when the user has enough time and when all users take care while loading. Time however is sometimes limited and last minute placements are then not made so carefully. In particular small children only partially open the dishwashing machine's door, partially draw out the upper basket and place their dishes anywhere in the front region of the basket. The invention provides a cutlery basket and a basket set designed to provide a quick access zone for last minute loading of the dishwashing machine.

According to claim 1 a cutlery basket for a dishwashing machine is provided which has a contoured bottom surface such that the cutlery basket is adapted to be placed on a contoured bottom in a dishwasher basket . Contoured means a shape or profile which deviates from the horizontal plane or from one vertical level. Small structures of the bottom wall which deviate from a horizontal plane are not meant hereby. Preferably the overall lower surface of the bottom element of the cutlery basket is contoured. Small structures are for example dipping aids often provided at the bottom of conventional cutlery baskets and being below 1 to 2 cm². The contour may comprise a curved region, stepped region, a cone, a dome, a partial cylinder mantle or the like. Inclined sections (relative to a horizontal plane) of the contour function as dripping aid as they drain washing liquid to lower parts of the bottom.

In a preferred embodiment the contour of the cutlery basket and the contour of the dishwasher basket mate to each other resulting in a proper mechanical support of the cutlery basket on the dishwasher basket.

When the overall (vertical) height of the cutlery basket is below 17 cm, 15 cm or 13 cm it is designed to be placed within the upper dishwasher basket . Particularly loading cutlery into the upper basket avoids multiple bending down of the user for each piece of cutlery. Preferably, the cutlery basket of the invention may be comprised in a quick access zone in the upper dishwasher basket.

According to one embodiment three foot points are provided. For example one or more additional legs extending downward from the bottom surface are provided which together with the lowest section of the contoured bottom surface span a triangle or a plane at one vertical level resulting in the basked being freestanding when placed on a horizontal working area. The one or more legs may be provided at positions such that the legs protrude through the mesh of the dishwasher basket when the cutlery basket is placed at a predefined location in the dishwasher basket .

In an embodiment a flexible mat device is provided to be arranged in the dishwashing basket, preferentially on the bottom of the basket. The flexible mat device has a base structure adapting at least in part flexibly or elastically to the contour of the bottom of the basket or to the contour of the place in the basket where the flexible mat device is placed. Depending on the need, the flexible mat device may be placed into the basket or removed from it. By the flexibility and in consequence by its at least partial adaptation to the contour of the basket, the mat device can be placed nearly at all desired portions within the basket, and on the other hand the volume required within the basket for placing the mat device is minimal. When it is removed, the flexible mat device may be bent, e.g. folded or rolled, and stored outside the dishwashing machine with minimum storing volume requirements. Due to its flexibility the flexible mat device or soft pad is at least partially elastic, so that it is bent, e.g. it gives way elastically, when cutlery or dishes are placed on top of the flexible mat device preventing damage to delicate dishes e. g. delicate glassware or additionally adapting to the form of the cutlery or dishes placed on the flexible mat device resulting in an improved support within the basket . In the present context, a dish or dishes which can be places on the flexible mat device of the invention preferably comprise (s) any plate, bowl, cup, pot, jug, pitcher, vas etc. which is made from an suitable material, such as e.g. china, earthenware, any plastics material or the like, s well as glassware of any kind which can be places on the flexible mat device of the invention, such as e.g. a drinking glass of any kind, a glass plate, glass bowl, class cup, glass pat, glass jug, glass pitcher, glass vase etc..

In a preferred embodiment, the flexible mat device or soft pad is made of an elastic material or it is at least partially coated with an elastic material, in particular with a soft material, such that damages to dishes, e.g. glassware are further reduced. Also lateral movements on the flexible mat device are inhibited while the basket is drawn out of or pushed into the dishwashing machine. In particular, if dishes or cutlery are loaded in last minute in a rush movement the dropping of the dishes is dampened thereby avoiding mechanical stress to the dishes. Therefore, the soft pad if the invention is a preferred component of a dishwasher basket of the invention which comprise a quick access zone. Further, the generation of noise while loading/unloading the dishes or cutlery and during the dishwashing program or the movement of the basket is reduced.

In another embodiment a mat device or soft pad is provided similar to the above mentioned flexible mat device, however comprising at least partially a rigid supporting structure. The supporting structure is at least partially covered by an elastic material, in particular a soft material, and/or a flexible structure, in particular a soft flexible structure, is attached thereto to place dishes or cutlery. The rigid supporting structure, which at least partially forms the base of the mat device can at least partially bridge or span steps or unevenness in a basket of a dishwashing machine. For example one end of the mat device may be placed against a side wall of the basket, while the other end rests on the bottom of the basket. Then the mat device is inclined within the basket and the dishes or cutlery are placed on the soft elastic material or on the flexible structure in the quick access zone of the mat device. In an embodiment, rigid supporting structure portions of the mat device are linked with flexible connection elements, such that also the mat device having a rigid supporting structure may be bent and partially adapted to the contour of the basket, depending on its orientation within the basket.

It should be noted that the mat device and the flexible mat device may also be used as a shelf or as a supporting pad, which either of provides the function of supporting dishes and cutlery and may optionally be placed within a basket of a conventional dishwashing machine at the desired location. In the following, when mentioning 'mat device ' , reference is normally made to the flexible mat device as well as to the mat device.

In a preferred embodiment a plurality of supporting elements like pins, are protruding from the base structure of a mat device (soft pad) and give an additional support for the cutlery and dishes placed on the mat device. Preferentially, the supporting elements are flexible or elastic, such that they are bent, when dishes like cups are placed on the mat device, thereby improving the mechanical stability of the placed goods. In a further preferred embodiment, the supporting elements are made of two components, a soft component for example on the surface on which the goods are placed, and a rigid one on the bottom side or in the core of the supporting elements. Alternatively, some or all of the supporting elements may be made of a semi-rigid material. In this case, the supporting elements are partially bent to a certain degree resulting in an adaptation to the contour of the goods placed on the mat device, while the semi-rigid supporting elements themselves exert a counter force onto the placed good.

In a further embodiment, the supporting elements are at least partially hollow, such that their flexibility is improved. On the other hand, the mat device may be positioned onto a pin, for example a pin of a plate insert, by inserting its tip into the recess of the supporting element. Thereby the mat device may be mounted to the pins of the basket or may be spanned between pins of the basket .

Preferably, the ground area of the flat mat device is significantly smaller than the ground area of the basket where the mat device is to be placed. For example, the area is smaller than one third of the basket's area, preferentially smaller than one forth or one fifth of this area. In preferred embodiments the mat device can be clipped to a wire of the dishwasher basket and/or it can simply be laid on the grid of the dishwasher basket .

Reference is made in detail to preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings which show:

Fig. 1 a perspective view on a soft pad, Fig. 2 the soft pad of Fig. 1 placed within a basket of a dishwashing machine, and

Fig. 3 an arrangement of the soft pad and two cutlery baskets in the basket.

Fig. 1 shows a perspective view on a soft pad 1 which is homogenously fabricated from a single elastic material by injection molding. The elastic material provides flexibility to adapt and change the basic form of the soft pad and results in an elastic surface of the soft pad in the areas where cutlery or dishes are placed. Further, the elastic material is resistant against the temperature and chemical conditions used during the dishwashing cycles. On the other hand, the soft pad has a residual rigidity, such that it at least partially stretches back to its base form as shown in Fig. 1, when no force is exerted to the soft pad 1.

The soft pad 1 comprises a base frame 3 formed of longitudinal bars 5 and cross bars 7, thereby forming an interlinked platform. The longitudinal bars 5 are extending beyond the cross bars 7 and are curved downward to bends 9. When placed in a basket, the downward bending bends 9 mesh with the grid of the basket, thereby laterally fixing the soft pad 1 within a basket 17 as shown in Fig. 2.

Perpendicular to the upper surface of the longitudinal bars 5 and cross bars 7 flexible fingers extend upward for receiving and supporting dishes and cutlery placed upon the soft pad 1.

Fig. 2 schematically shows the soft pad 1 of Fig. 1 placed within the basket 17 (only partially shown) . The grid of the basket 17 is formed of side bars 19 and bottom bars 21. The soft pad 1 is placed here at the center front section of the upper basket 17. A cup 15 is placed on the soft pad 1 where the rim of the cup 15 is placed between the flexible fingers. Where the rim of the cup 15 runs over the center of fingers 11, the fingers are bent by the cup 15 and abut against the side or inner wall of the cup, as for example shown by fingers 11a and lib.

The soft pad placed in the front section of the upper basket of a dishwashing machine provides a quick access zone for the user. Even if the washing machine's door is only partially opened and the upper basket is only partially drawn out of the tub, the user may place the dishes and cutlery even in a hastily manner upon the soft pad 1 without damage due to its soft and elastic bearing surface.

Fig. 3 shows a basket set, comprising a quick access zone, consisting of the upper basket 17, the soft pad 1 placed at a center front section of the basket, and two cutlery baskets 30 positioned in glass support columns 23 of the basket 17. As in Fig. 2 the cup 15 is placed on the soft pad 1, a saucer 16 is placed in a plate insert of the basket 17, and a spoon 36 as well as a fork 42 are deposited in the opening 34 of the right cutlery basket 30.

In the depicted embodiment the two cμtlery baskets 30 are identically formed and exchangeable. Both or one of them can be removed from the basket 17 dependent on the user's need for supporting space for glasses in the glass supports 23 or for storing space for cutlery. The cutlery basket height from the lowest point to the upper rim is about 14 cm and they are designed for receiving short cutlery like spoons, knifes, pastry forks and so on. To optimally use the limited height from the bottom of the upper basket to the upper tub wall of a dishwashing machine, the bottom of the cutlery basket is adapted to the curvature given by the contour of the bottom of basket 17. As the supporting surfaces of left and right glass supports 23 are formed by inclined bars 25 which are inclined to the horizontal plane except a short horizontal section at the outer periphery, the cutlery baskets 30 have correspondingly inclined lower surfaces 36 mating with the contour of the glass supports 23. The inclination angle of at least a portion of the cutlery basket ' s bottom is in the range of 10° to 40°, preferentially in the range from 15° to 30°.

The side and bottom walls of the cutlery baskets are provided with holes 32 for spraying the washing liquid in and draining it out. The dripping off of washing liquid benefits from the inclined bottom form. By this way no shaping using small contours like array-arranged pyramids at the horizontal bottom of conventional cutlery baskets is required.

The inside of the cutlery baskets 30 is divided into several compartments (here six in a 2x6 array - not shown) and due to the inclination of the bottom, the depth of the compartments varies from the inner to the outer side of the cutlery baskets. Medium length cutlery can be placed in the compartments having the greater depth while short cutlery can be placed in the compartments having the smallest depth. When unloading the cutlery baskets 30 the picking out of short cutlery is improved thereby, avoiding for example a puncture of the user's hand by forks or knives stored in the same compartment .

As mentioned above in connection with last minute loading of dishes and cutlery on the soft pad 1, the arrangement of one or more cutlery baskets at a right and/or left front section of a dishwasher basket, preferably of the upper dishwasher basket, extends the quick access zone by the cutlery basket (s) which, when placed in the front of the upper basket 17, can also be loaded with the door of the dishwashing machine partially opened and the upper basket only partially drawn out .

In an embodiment not shown here, the cutlery basket 30 has mounting or fixing means to attach the cutlery basket in a >, mechanically stable way to the basket 17. In another embodiment, the sidewalls and/or the compartment walls of the cutlery basket are inclined relative to the vertical axis. Thereby the cutlery basket can be placed in e.g. in the upper basket 17 of a dishwashing machine with an orientation towards a ceiling shower arranged at the center of the upper tub wall . Thereby the amount of washing liquid sprayed into the cutlery basket is increased.

In another embodiment the cutlery basket's bottom is contoured as such, however the contour is formed in a manner or legs are provided extending from the lower surface such that the cutlery basket can be placed on a horizontal plane when taken out of the dishwashing machine's basket. For example the cross-section of the lower surface 36 of the cutlery basket 30 (e.g. in the plane as shown in Fig. 3) is formed like a sawtooth such that the basket can stand on a horizontal working area with the left and right bottom ends . For example the width of the left cutlery basket 30 as shown in Fig. 3 extends beyond the glass support 23 towards the right side and subsequently to the upward incline of the bottom element of the cutlery basket, which is parallel to the inclined bar 25 of the upper basket 17, the bottom element of the cutlery basket is provided with a downward step ending on the basket's bottom having the same level as the horizontal section of inclined bar 25 on the left side of the cutlery basket 30. In this way or using one or more legs extending downward from the bottom the cutlery basket has at least three foot points arranged in a horizontal plane. Reference Numerals List
