Roller washing and drying machine, and method for controlling drying process

Abstract

PROBLEM TO BE SOLVED: To provide a drum type washing-drying machine which has less unevenness in drying in the drying process.SOLUTION: When the amount of laundry in the rotary drum is within a rated drying capacity, and also, is not determined to be the maximum (drying capacity maximum), the control of the drying process is set so that the drying process by a normal operation being shown by a curve 96 of a broken line may be performed. For the normal operation, e. g. , the rotary drum is operated by repeating a normal rotation, a pause and a reverse rotation at 40 to 55 rotations per minute. When it is determined that the laundry is the maximum (drying capacity maximum), the drying process including a rotation variable operation being shown by a curve 97 of a solid line is performed. For the operation including the rotation variable operation, the rotation variable operation, in which the rotation speed of the rotary drum is raised in steps when started, and is raised to the rotation speed of a degree in which a space is formed at the central section of the laundry, and then, the rotary drum is suddenly stopped, is inserted in the normal operation. By the sudden stoppage after the high speed rotation, the exchange of the laundry on the external side in the radial direction and on the internal side in the radial direction of the rotary drum can efficiently be performed.

Description

technical field [0001] The invention relates to a drum type washing and drying machine, in particular to a method for controlling the drying process. Background technique [0002] Patent Document 1 (paragraphs 0026 to 0031 of Japanese Patent Application Laid-Open No. 2006-204428) discloses a drum-type washing and drying machine as follows: In the drying process of the drum-type washing and drying machine, in order to untangle the laundry, To improve drying unevenness, increase the unraveling process of increasing the rotational speed of the rotary drum compared to the general rotational speed in the drying process. [0003] In the drum type washing and drying machine, the laundry near the rated drying capacity is stored in the rotating drum. During the drying process, the laundry in the rotating drum is attached to the inner periphery due to centrifugal force before and after dehydration, and in the center There may be a little room at the bottom. However, in the drying pr...

Problems solved by technology

That is, the drying process is carried out in a state where the transition between the central part and the outer peripheral part of the laundry in the rotary drum is extremely poor, and the warm air only flows through the front part and the outer peripheral part of the rotary drum to dry, so the laundry The problem that the center part of the center part does not dry and the unevenness of drying increases
