Definitions
- the subject matter of the present disclosure relates generally to an assembly for holding articles in a rack assembly of a dishwashing appliance.
- Modern dishwashers typically include a wash chamber where e.g., detergent, water, and heat can be applied to clean food or other materials from dishes and other articles being washed.
- an upper rack assembly is disposed close to the top of the wash chamber and is used to hold glasses, cups, and other small items.
- a lower rack assembly is positioned near the bottom of the chamber and a considerable distance below the upper rack. This provides vertical clearance to place dishes and platters on edge (i.e. a vertical orientation) and to place food preparation bowls and pots up-side-down on the lower rack for washing.
- Each rack normally is supplied with an array of spaced apart, generally vertical tines or members, which support and separate the individual items. These vertical members support and fix the position of various articles during the washing process. More specifically, it is desirable to position an article, such as a dish, so that water and detergent can access all surfaces during cleaning while also preventing movement of the dish that could lead to breaking, chipping, or other damage.
- Articles that may be placed in a dishwasher can vary substantially in size and type. Dishes, pots, pans, glasses and the like can differ in both shape and size. The same wash load may include a variety of these differently shaped and sized articles.
- the vertical tines can be provided with features in an effort to accommodate such variations in the articles. For example, tines that can be folded between various positions can provide for adjustment to different shapes and sizes. Tines can also be shaped in configurations that help accommodate variations as well.
- the position of the tines within a rack assembly of a dishwasher is fixed. More particularly, the rack assembly is usually constructed of elongated metal rods that are joined together by e.g., welding. The tines are also permanently affixed to the elongated rods of the rack assembly.
- Such permanent positioning of the tines can be undesirable for several reasons.
- the consumer may wish to change the direction of the offset.
- the consumer may wish to rotate the direction of the offset of the tines for more convenience in loading and unloading articles.
- the overall position of the tines within the rack assembly relative to e.g., the sides the rack assembly may not provide a good fit for certain articles from being placed into the rack.
- each such configuration can require a separately manufactured rack assembly.
- the present invention provides an assembly of tines for a dishwashing appliance that can be repositioned within and/or removed from a rack assembly. For example, a user can reverse the direction of the tine assembly based upon the location of a dishwasher in the kitchen. The tines can be moved relative to the side or wall of the rack assembly to accommodate different article sizes. The tines can also be completely removed from the rack assembly if needed to accommodate a large article. Additional, a degree of modularity is provided in that the same rack assembly may be provided with different tine assembly configurations so as to e.g., simplify the manufacturing process.

Description
- The subject matter of the present disclosure relates generally to an assembly for holding articles in a rack assembly of a dishwashing appliance.
- Modern dishwashers typically include a wash chamber where e.g., detergent, water, and heat can be applied to clean food or other materials from dishes and other articles being washed. Often an upper rack assembly is disposed close to the top of the wash chamber and is used to hold glasses, cups, and other small items. Typically, a lower rack assembly is positioned near the bottom of the chamber and a considerable distance below the upper rack. This provides vertical clearance to place dishes and platters on edge (i.e. a vertical orientation) and to place food preparation bowls and pots up-side-down on the lower rack for washing.
- Each rack normally is supplied with an array of spaced apart, generally vertical tines or members, which support and separate the individual items. These vertical members support and fix the position of various articles during the washing process. More specifically, it is desirable to position an article, such as a dish, so that water and detergent can access all surfaces during cleaning while also preventing movement of the dish that could lead to breaking, chipping, or other damage.
- Articles that may be placed in a dishwasher can vary substantially in size and type. Dishes, pots, pans, glasses and the like can differ in both shape and size. The same wash load may include a variety of these differently shaped and sized articles.
- The vertical tines can be provided with features in an effort to accommodate such variations in the articles. For example, tines that can be folded between various positions can provide for adjustment to different shapes and sizes. Tines can also be shaped in configurations that help accommodate variations as well.
- Typically, the position of the tines within a rack assembly of a dishwasher is fixed. More particularly, the rack assembly is usually constructed of elongated metal rods that are joined together by e.g., welding. The tines are also permanently affixed to the elongated rods of the rack assembly.
- Such permanent positioning of the tines can be undesirable for several reasons. For example, where individual tines are each configured with an offset to one side the dishwasher, the consumer may wish to change the direction of the offset. Depending on the location of the dishwasher in a kitchen relative to e.g., the sink, the consumer may wish to rotate the direction of the offset of the tines for more convenience in loading and unloading articles. Also, the overall position of the tines within the rack assembly relative to e.g., the sides the rack assembly may not provide a good fit for certain articles from being placed into the rack. In addition, where a manufacturer wishes to provide different rack assemblies having different configurations of tines, each such configuration can require a separately manufactured rack assembly.
- Aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.
- The present invention provides an assembly of tines for a dishwashing appliance that can be repositioned within and/or removed from a rack assembly. For example, a user can reverse the direction of the tine assembly based upon the location of a dishwasher in the kitchen. The tines can be moved relative to the side or wall of the rack assembly to accommodate different article sizes. The tines can also be completely removed from the rack assembly if needed to accommodate a large article. Additional, a degree of modularity is provided in that the same rack assembly may be provided with different tine assembly configurations so as to e.g., simplify the manufacturing process.
- For example, in on exemplary embodiment, the present invention provides a removable tine block assembly for a dishwasher appliance. The tine block assembly defines longitudinal and lateral directions. The assembly includes a pair of elongated base members extending parallel to each other along the longitudinal direction and spaced apart from each other along the lateral direction. A plurality of tines extend vertically from the elongated base members and are spaced apart from each other along the longitudinal direction and arranged in corresponding pairs along the lateral direction. A pair of transverse members extends along the lateral direction and connecting the base members. The transverse members define a pair of hooks that face along the longitudinal direction and are configured for removable attachment to a laterally extending member of a dishwasher rack assembly.
- In another exemplary embodiment, the present invention provides a dishwasher rack assembly that includes a bottom wall formed of a first set of elongated spaced apart rods crossed by a second set of spaced apart rods to define an open lattice structure. A tine block assembly is removably attached to the bottom wall. The tine block assembly includes a pair of elongated base members extending parallel to each other along the longitudinal direction and spaced apart from each other along the lateral direction; a plurality of tines extending vertically from said elongated base members, the tines spaced apart from each other along the longitudinal direction and arranged in corresponding pairs along the lateral direction; and a pair of transverse members extending along the lateral direction and connecting the base members, the transverse members defining a pair of hooks that face along the longitudinal direction and are configured for removable attachment to at least one of the rods of the bottom wall.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
