Tub construction for dishwasher

Abstract

A tub construction for a dishwasher is provided. The tub construction includes an upper panel, a lower panel disposed below the upper panel, and an intermediate panel perpendicularly connecting the upper and lower panels. The tub construction of the present invention not only allows for a quicker assembly of the tub, but also an easier changing of the tub's outer dimensions. Furthermore, when seam welding, by changing the dimensions of the flanges at the corners, wrinkles at the corners are prevented, creating an even, leak-proof welding line.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a dishwasher, and more particularly, to a tub construction of a dishwasher. [0003] 2. Description of the Related Art [0004] In general, high-pressure jets of washing water are emitted from upper and / or lower nozzles inside a dishwasher tub to remove food particles on dishes inside the dishwasher. [0005]FIG. 1 is an exploded view showing a process of assembling a related art dishwasher tub. [0006] Referring to FIG. 1, a related art dishwasher 10 has a U-panel 11 forming the sides and top facets of the tub, welded to an L-panel 12 forming the back and bottom facets of the tub. In further detail, such a related art tub, having a U-panel 11 forming the sides and top facets of the tub with a single plate and an L-panel 12 forming the back and bottom facets of the tub with a single plate, allows a continuous weld line (L) to be used to weld the two panels together to form the tub.

Benefits of technology

[0013] An object of the present invention is to provide an improved construction for a dishwasher tub that minimizes the time required for tub assembly and facilitates changing of the tub's outer dimensions.

[0014] Another object of the present invention is to provide a construction for a dishwasher tub having a simplified tub assembly process, thereby improving the manufacturing efficiency of the tub.

[0015] A further object of the present invention is to provide a construction for a dishwasher tub that is not subject to wrinkling from seam welding corners, and has a uniform weld that is not prone to leaks.

[0019] The above constructions for a dishwasher tub not only provide a comparatively faster time in which assembly is completed, but also allows a change in the outer dimensions of the tub.

[0020] Also, when seam welding, the dimensions of the flanges at the corners can be varied so that there are no wrinkles created, and thus, no leakage at the welded corner flanges.

Problems solved by technology

It follows from the complicated welding process that the manufacturing process of the tub is lengthened, reducing productivity.

In addition, when the above tub assembling process is used, the weld line does not occur on the same two-dimensional plane, but curves three-dimensionally, thereby making it difficult to change the dimensions of the tub.

Also, seam welding, which is used in the above procedure, does not dispense the same amount of welding material on the corners as is dispensed on the straight weld portions, creating wrinkles and uneven seaming lines.
