Abstract
The present disclosure relates to a dishwasher in which dry air spraying from an airflow guide is evenly distributed into a tub not to concentrate heat energy of the dry air on a specific portion, thereby reducing a dry period for wash targets and improving drying efficiency, and effectively preventing deterioration in drying efficiency, which is caused by a change in the direction of a discharge opening when misassembly occurs.
Claims19
A dishwasher, comprising:
- a tub that defines a wash space configured to accommodate a wash target, the tub having a front surface that is open;
- a dry air supply configured to generate dry air for drying the wash target and to supply the dry air into the wash space;
- a rack configured to be inserted into and withdrawn from the wash space through the front surface of the tub, the rack being configured to support the wash target;
- and
- an airflow guide disposed between the rack and a lower surface of the tub, the airflow guide being configured to define a flow direction of the dry air and to spray the dry air into the wash space,
- wherein the airflow guide is disposed rearward relative to the rack,
- wherein the airflow guide defines a discharge opening configured to spray the dry air to the wash space,
- wherein a height of the discharge opening in an up-down direction is constant, and
- wherein the discharge opening is configured to:
- spray a first portion of the dry air toward a first space between the rack and a rear surface of the tub, and
- spray a second portion of the dry air toward a second space defined between the lower surface of the tub and the rack.

- a dry air supply configured to generate dry air for drying the wash target and to supply the dry air into the wash space;
- a rack configured to be inserted into and withdrawn from the wash space through the front surface of the tub, the rack being configured to support the wash target;
- and
- an airflow guide disposed between the rack and a lower surface of the tub, the airflow guide being configured to define a flow direction of the dry air and to spray the dry air into the wash space,
- wherein the airflow guide is disposed rearward relative to the rack,
- wherein the airflow guide comprises:
- a lower guide coupled to the dry air supply and configured to receive the dry air generated from the dry air supply,
- an upper guide fastened to an upper side of the lower guide,
- a discharge opening defined between the lower guide and the upper guide and configured to spray the dry air to the wash space, and
- a misassembly prevention part configured to place the upper guide at a predetermined position relative to the lower guide,
- wherein the lower guide comprises:
- a reference surface that defines a lower end edge of the discharge opening, and
- a guide main body that has a plate shape,
- wherein the upper guide has an open lower surface that is coupled to the guide main body,
- wherein the misassembly prevention part comprises a misassembly prevention groove that is recessed relative to the reference surface in an up-down direction and extends along an outer edge of the guide main body, and
- wherein the misassembly prevention groove is configured to:
- based on the upper guide being arranged in the predetermined position, receive a lower end portion of the upper guide into the misassembly prevention groove, and
- based on the upper guide being arranged outside the predetermined position, be disposed offset from the lower end portion of the upper guide and restrict the lower end portion of the upper guide from being inserted into the misassembly prevention groove.
