The camera module includes a first reflective member including a receiving groove formed on one surface thereof and a first optical surface provided within an area provided by the receiving groove, a second reflective member including a protrusion protruding from one surface thereof and at least partially accommodated in the receiving groove, and a second optical surface provided on one surface of the protrusion to be disposed to face the first optical surface, and an image sensor configured to detect at least a portion of light guided via the first optical surface and the second optical surface, wherein the receiving groove is configured to allow the protrusion to move in a first extension direction in a plane parallel to the first optical surface or the second optical surface, and to inhibit a movement of the protrusion in a second extension direction crossing the first extension direction.

Abstract: Provided is a dishwasher, which includes a washing space, a sump, a water supply device, a heater, a control part. The washing space includes a rack accommodating a dish, and a nozzle for spraying washing water. The sump collects the washing water supplied to the washing space. The water supply device supplies the washing water to the sump. The heater is in the sump and heats the washing water. The control part controls a washing process where washing water including a detergent is sprayed toward the dish, and a rinsing process where the dish is rinsed after the washing process. The rinsing process includes a first rinsing operation where the washing water stored in the sump is sprayed to the nozzle after the washing process, a second rinsing operation where the washing water heated by the heater is sprayed through the nozzle after the first rinsing operation, and a third rinsing operation where the washing water in the sump is sprayed through the nozzle after the second rinsing operation.
