Dishwasher and method for controlling same

Abstract

A dishwasher includes a casing arranged within the dishwasher, an odor eliminating material installed within the casing, a shutter which selectively opens a part of the casing to expose the odor eliminating material, and a shutter driving device which operates the shutter. A control unit of the dish washer counts an actual drying time in a drying operation of the dishwasher, and opens the shutter by operating the shutter driving device in response to the counted drying time being equal to or greater than a preset drying time. The odor eliminating material eliminates odors in the dishwasher.

Description

technical field [0001] The present invention relates to a dishwasher, and more particularly to a dishwasher and a method of controlling the same for removing unpleasant odors in the dishwasher. Background technique [0002] Generally, a dishwasher is a device that operates by supplying washing water into a washing tub of the dishwasher and spraying the washing water through nozzles while circulating the washing water in the washing tub to coincide with washing, rinsing, and drying operations. [0003] In this type of dishwasher, food residue remains in the drain filter in the wash tub after washing is completed. In this case, the odor generated by the food residues filtered by the drain filter pervades the space of the dishwasher and causes discomfort to the user. [0004] Thus, various methods of removing unpleasant odors in the dishwasher space have been proposed.

Problems solved by technology

[0014] However, the conventional dishwasher with the above-mentioned structure needs an additional communicating pipe in which the adsorption element, heater, insulating material, exhaust fan and filter must be arranged

This complicates the structure and assembly of the dishwasher, and increases the manufacturing cost of the dishwasher

[0015] In addition, conventional dishwashers have problems in their efficiency in eliminating odors because the adsorption element is arranged in a communication pipe located outside the dish washing space

Therefore, it is difficult for the adsorption element to communicate with the air inside the dish washing space

Furthermore, conventional dishwashers have the problem that the exhaust fan must always be driven excessively in order for the air in the dish washing space to be easily conveyed and drawn through the adsorption element
