Abstract
A dishwasher includes a sorption drying device in which a heater is disposed in a linear air flow path extending in a downward inclination angle, at least a portion of air that has passed through the linear air flow path collides with a bottom surface of a moisture absorbent receiving portion and thus is introduced to a lower side of the moisture absorbent, so that a separate means for flow distribution is omitted, and heated air through the heater is evenly introduced to the moisture absorbent at a minimized flow resistance.
Claims20
A dishwasher comprising:
- a tub that defines a washing space configured to accommodate one or more objects to be washed;
- and
- a sorption drying device configured to absorb moisture from air discharged from the tub and to supply the air to the tub based on the moisture being absorbed,
- wherein the sorption drying device comprises:
- a blow fan configured to generate air flow of the air,
- a moisture absorbent disposed downstream relative to the blow fan in a flow direction of the air flow,
- a heater disposed between the blow fan and the moisture absorbent in the flow direction of the air flow, the heater being configured to heat the air to be supplied to the moisture absorbent,
- a heater receiving portion that defines a heater receiving space accommodating the heater therein, the heater receiving portion having (i) a first inlet configured to receive the air having passed through the blow fan and (ii) a first outlet configured to discharge the air having passed through the heater, and
- a moisture absorbent receiving portion that defines a moisture absorbent receiving space accommodating the moisture absorbent therein, wherein the moisture absorbent receiving space is configured to receive the air having passed through the heater receiving portion,
- wherein the moisture absorbent receiving portion further defines an air introduction space disposed upstream relative to the moisture absorbent receiving space in the flow direction of the air flow, wherein the air introduction space is configured to receive the air having passed through the heater receiving space,
- wherein the heater receiving space extends toward the air introduction space,
- wherein the moisture absorbent receiving space has a second inlet configured to receive the air having passed through the first outlet and the air introduction space, and
- wherein a vertical width between a bottom surface of the air introduction space and a top surface of the air introduction space decreases as the air introduction space extends away from the second inlet.
