Abstract

Disclosed herein is a dishwasher. The dishwasher includes, a tub provided in the cabinet to form a washing chamber, and a drying apparatus arranged on a side wall of the tub and including a flow path provided to allow air sucked from the washing chamber to flow, a heater arranged in the flow path to heat air in the flow path, and a switch arranged upstream of the heater to turn off the heater in response to air, which is adjacent to the heater, reaching a predetermined temperature.

First claim

What is claimed is:

1 . A dishwasher comprising:
a tub forming a washing chamber; and a drying apparatus disposed on a side wall of the tub, and comprising:
a flow path configured to guide air sucked from the washing chamber,
a heater disposed in the flow path and configured to heat the air in the flow path, and
a switch positioned upstream of the heater and configured to turn off the heater in response to the air, which is adjacent to the heater, reaching a predetermined temperature.

2 . The dishwasher of claim 1 , wherein:
the drying apparatus further comprises a fan positioned upstream of the heater on the flow path to move the air through the flow path, and the switch is positioned downstream of the fan and upstream of the heater.

3 . The dishwasher of claim 2 , wherein the drying apparatus further comprises a temperature sensor positioned downstream of the heater in the flow path and configured to detect a temperature of the air passing through the heater.

4 . The dishwasher of claim 3 , wherein the fan, the switch, the heater and the temperature sensor are sequentially arranged from an upper side to a lower side.

5 . The dishwasher of claim 3 , wherein:
the drying apparatus further comprises:
a first housing coupled to an outer surface of the tub and extending in a vertical direction; and
a second housing extending in the vertical direction and coupled to the first housing so as to form the flow path with the first housing, and
the fan, the switch, the heater, and the temperature sensor are disposed between the first and second housings.

6 . The dishwasher of claim 5 , further comprising:
a cabinet configured to accommodate the tub, wherein the second housing comprises a plurality of separation ribs protruding from an outer surface of the second housing toward the cabinet to space the outer surface of the second housing from an inner surface of the cabinet.

7 . The dishwasher of claim 1 , wherein the drying apparatus comprises:
an inlet configured to allow air in the washing chamber to enter into the flow path; and an inlet cover disposed on an inner surface of the tub to cover the inlet so as to prevent foreign substances or washing water in the washing chamber from entering the flow path.

8 . The dishwasher of claim 7 , wherein:
the drying apparatus further comprises a housing coupled to an outer surface of the tub, and the inlet cover is removably coupled with the housing.

9 . The dishwasher of claim 8 , wherein the inlet cover is rotatably coupled to the housing.

10 . The dishwasher of claim 9 , further comprising:
a coupling member configured to couple the inlet cover to the housing and the inlet cover.

11 . The dishwasher of claim 10 , wherein:
the coupling member is formed in an annular shape, and comprises a coupling rib protruding in a radial direction from an outer circumferential surface of the coupling member, and the housing comprises a receiving rib protruding toward the inlet cover and configured to receive the coupling rib.

12 . The dishwasher of claim 7 , further comprises:
a basket movably disposed in the washing chamber and configured to accommodate a dish, wherein the inlet cover is disposed adjacent to a rear wall of the tub and configured to prevent interference with the dish accommodated in the basket in response to inserting or withdrawing the basket.

13 . The dishwasher of claim 7 , further comprising:
a basket disposed in the washing chamber and configured to accommodate a dish; and an inlet space formed between the inlet cover and the inlet and configured to allow air in the washing chamber to flow to the inlet, wherein the inlet cover comprises:
a base member disposed adjacent to an inner wall of the tub so as not to interfere with the basket; and
a protrusion protruding from the base member toward an inside of the washing chamber to form the inlet space.

14 . The dishwasher of claim 10 , wherein:
the inlet cover comprises an intake through which air in the washing chamber is introduced, and the coupling member comprises a prevention portion protruding toward the washing chamber and configured to prevent foreign substances or washing water in the washing chamber from entering the washing chamber through the intake.

15 . The dishwasher of claim 1 , wherein the heater comprises:
a power connection terminal configured to receive power to operate the heater; and a sheath heater connected to a bottom side of the power connection terminal and configured to receive power from the power connection terminal to heat the air in the flow path.
