PROBLEM TO BE SOLVED: To eliminate wait time, effectively perform rinsing, and eliminate resonance of a body.SOLUTION: The drum-type washing machine includes: a shower nozzle for diffusion-injecting water in a form of shower while turning water toward inside a drum; a drive part (17) rotationally driving the drum; a speed control part (47) for variably controlling a rotational speed of the drum; a shower water supply part (14) for supplying water to the shower nozzle; and a control unit (41) for controlling the drive part (17), the speed control part (47) and the shower water supply part (14) to perform a washing step, a rinsing step and a dewatering step. The control unit (41) includes a shower rinsing control part (49) that controls the shower water supply part (14) to supply water to the shower nozzle, while instructing the speed control part (47) to control a rotational speed of the drum to be a rinsing rotational frequency that is higher than a resonance rotational frequency at which an outer box resonates in a shower rinsing process.SELECTED DRAWING: Figure 5 |
