Abstract
A dishwasher has a first predetermined separation space defined between a heater housing and a main housing, to provide a heat insulation air layer for a heater and a heater housing, thereby minimizing a release of heat of the heater to the outside of the main housing and ensuring improvement in energy efficiency.
Claims19
A dishwasher, comprising:
- a tub that defines a wash space configured to accommodate one or more objects to be washed;
- and
- a moisture-absorbing and drying device configured to absorb moisture from air discharged from the tub and to supply the air to the tub,
- wherein the moisture-absorbing and drying device comprises:
- an air blowing fan configured to generate an air current of the air,
- an absorbent disposed downstream relative to the air blowing fan in a flow direction of the air current,
- a heater disposed between the air blowing fan and the absorbent in the flow direction of the air current, the heater being configured to heat the air current to be supplied to the absorbent,
- a heater housing that accommodates the heater, and
- a main housing that accommodates the heater housing and the absorbent,
- wherein the heater housing is spaced apart from an inner surface of the main housing to thereby define a first separation space between the heater housing and the inner surface of the main housing, and
- wherein the heater housing comprises a lower bead that protrudes from a lower surface of the heater housing toward a bottom surface of the main housing, the lower bead being configured to support the lower surface of the heater in a state where the lower surface of the heater housing is spaced apart from the bottom surface of the main housing.

A dishwasher, comprising:
- a tub that defines a wash space configured to accommodate one or more objects to be washed;
- and
- a moisture-absorbing and drying device configured to absorb moisture from air discharged from the tub and to supply the air to the tub,
- wherein the moisture-absorbing and drying device comprises:
- an air blowing fan configured to generate an air current of the air,
- an absorbent disposed downstream relative to the air blowing fan in a flow direction of the air current, and
- a double structure that accommodates the absorbent, the double structure comprising (i) a main housing that accommodates the absorbent and (ii) a sub housing coupled to an outer surface of the main housing,
- wherein a least a portion of the sub housing is spaced apart from the main housing to thereby define a separation space between the main housing and the sub housing,
- wherein the sub housing comprises a protrusion rib that protrudes from an inner surface of the sub housing toward the outer surface of the main housing and contacts the outer surface of the main housing, and
- wherein the protrusion rib defines a height of the separation space corresponding to a length of the protrusion rib protruding from the inner surface of the sub housing toward the outer surface of the main housing.
