Description

  The present invention relates to a washing machine and a washing / drying machine provided with an operation display device that performs display corresponding to an operation button group or an operation touch panel operation on a display device arranged adjacent to the operation button group or the operation touch panel. It is.

  A conventional operation display device for a washing machine is mainly provided with an operation button for operating the display device adjacent to a display device in which a plurality of display portions for displaying an operation time and an operation state are combined.

  These display devices have a structure in which a display portion represented by printed characters or the like at a predetermined position of the display device and a light source unit such as an LED representing selection or operation are provided in pairs, and the display device is a liquid crystal display device What consists of is known.

  As the liquid crystal display device, a character display device in which display content is fixed and a dot matrix display device in which display content is not fixed are generally known. In washing machines, proposals have been made that employ the two display devices.

  Furthermore, when a dot matrix liquid crystal is employed in a display device, an operation display device is known in which an operation touch panel is combined with the upper surface of the display device.

  Modern washing machines can automatically drive a preset course by operating a start button, but many courses and detailed settings are possible in response to various needs. In recent large-scale washing machines, which have a drying function, an operation display unit for setting and displaying the operation is enlarged.

  However, due to recent improvements in washing machine performance, very detailed control is performed, which may cause operations that are difficult for the user to understand.

  For example, in the case of a drum-type washing machine, it is necessary to rotate the drum at a higher speed in order to obtain a higher dewatering rate by the dewatering operation. At this time, if the clothes are arranged in the drum, the eccentricity occurs, and vibration due to the drum rotation is greatly generated, which is dangerous. Therefore, high-speed rotation cannot be performed.

  In this case, a water injection / low rotation operation called “unwinding” operation for correcting the eccentricity of clothing is performed, but this operation is difficult for the user to understand. Patent Document 1 proposes a washing machine that shows a user an appropriate driving state with easy-to-read display contents.

Japanese Patent Laid-Open No. 2001-56145

  In the washing machine disclosed in Patent Document 1, it is possible to indicate a driving state that is difficult for the user to understand. However, the user can view the display information only when the user is near the washing machine.

  When troubles in continuation of operation occur in the washing process or dewatering process, such as the defoaming operation when a lot of detergent is thrown in, the operation history that solves the trouble is recorded in nonvolatile memory for maintenance purposes. There are many cases.

  The purpose of the present invention is not only to display that the operation that solves the obstacle to the continuation of the operation that is difficult for the user to understand is performed, but also to display information diagnosed from the record of the operation history before starting the next operation. It is to provide a washing machine that reduces the occurrence of troubles in driving continuity by showing to the user.
