Benefits of technology

[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.

Embodiment Construction

[0030] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0031]FIG. 2 is a sectional view of a dishwasher with a tub according to an embodiment of the present invention.

[0032] Referring to FIG. 2, a dishwasher having the tub construction of the present invention has a tub 200 forming an exterior and having dishwasher parts formed therein, a door 111 pivotably formed to open and close at the front of the tub 200, and a sump 170 formed at the central bottom portion of the tub 200 for holding washing water.

[0033] Also, a wash pump 180 is connected to the sump 170 for high-pressure pumping of the washing water stored in the sump 170, and a motor 190 attached to the rear of the wash pump 180 for driving the wash pump 180.

[0034] In addition, the dishwasher includes...

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. [0007] H...
