Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fully automatic washing machine that uses a control device such as a microcomputer to control the display of abnormality details when an abnormality occurs.

BACKGROUND OF THE INVENTION Conventionally, in this type of fully automatic washing machine, as shown in FIG. 4, a control means 4 for controlling a series of sequential operations of washing, rinsing, and spin-drying displays the contents of each process of washing, rinsing, and spin-drying. It is connected to display means 6. This display means 6 is composed of a progress display section 6a that displays the distinction between washing, rinsing, and dehydration steps, and a remaining time display section 6b that displays the time until the process is completed.

However, the display means 6 does not inform the user that an abnormal condition such as a water supply abnormality, a drainage abnormality, or an unreleased lance abnormality has occurred during each washing, rinsing, and dehydration process, and that the condition is being resolved. By a combination of flashing and lighting of the plurality of indicator lights in the progress display section 6a, and by using the remaining time display section 6b, the details of the abnormality are displayed using symbols such as alphabets instead of numbers that normally indicate time. It was something.

Problems to be Solved by the Invention This conventional configuration has a problem in that even if the progress display section 6a is used, the presence or absence of an abnormal state or the content of the abnormality cannot be clearly determined at a glance. Further, when displaying using the remaining time display, an indicator light for displaying numbers is required, and there is a problem that this is not possible with low-priced washing machines that do not use indicator lights for displaying numbers.

The present invention solves these problems by making it possible to distinguish the presence or absence of an abnormal state or the content of the abnormality at a glance, and to distinguish the presence or absence of the abnormal state and the content of the abnormality without using a remaining time indicator. The purpose is to display the following information.

Means for Solving the Problem In order to solve this problem, the present invention does not use the progress display section for abnormality display, but replaces the existing washing time setting display section.

A plurality of indicator lights in the rinse setting display section and the dehydration time setting display section are used to display the presence or absence of an abnormal condition, the distinction of the contents of the abnormal condition, or the fact that the resolution of the abnormal condition is under control.

Function: With this configuration, there is no need for an indicator light for numerical display, and the multiple indicator lights of the existing washing time setting display section, rinse setting display section, and spin time setting display section can be used together, and the indicator lights can be blinked and turned on. Therefore, the presence or absence of an abnormal state or the content of the abnormality can be clearly determined at a glance.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3. In FIG. 1, the display means 5 for displaying the operation contents of each process of washing, rinsing, and spin-drying under the control of the control means 4 is a washing time constituted by a plurality of indicator lights that display the setting of the washing time or the remaining time. A setting display section 5a, a rinse setting display section 5 composed of a plurality of indicator lights that display the setting of the rinse type or the remaining time.
b. A dehydration time setting display section 5C1 consisting of a plurality of indicator lights that display the dehydration time setting or remaining time.
It is composed of a progress display section 5d that displays which process of washing, rinsing, and dehydration is being performed.

The control means 4 is washed and rinsed as shown in FIG.

It is comprised of a discrimination means 1 for determining the occurrence of an abnormality in each step of dehydration, a microcomputer 2, and a solving means 3 for eliminating the abnormality. The microcomputer 2 includes an input section 2b for inputting the output of the discriminating means 1, an output section 2d for outputting a signal to the solving means 3, a storage section 2a storing a program, and the storage section 2a, the input section 2b, and the output section. 2d and performs data comparison calculations and the like. When the discriminator 1 determines that the water supply is abnormal as an abnormal mode, the plurality of indicator lights in the washing time setting display section 5a blink and turn on, and when a drainage abnormality occurs, the rinse setting is set. By blinking and lighting a plurality of indicator lights on the display section 5b, and when an imbalance abnormality occurs, the display is distinguished by blinking and lighting a plurality of indicator lights on the dehydration time setting display section 5C.

In addition, when an unbalanced state of the cloth occurs during the dewatering process, in order to display that the solving means 3 is controlling the resolution of the state, the Susuki setting display section 5b and the dehydration time setting display section 5c are provided. The user is notified by blinking and lighting a combination of a plurality of indicator lights.

Next, the operation of this embodiment will be explained using a flowchart.

In FIG. 3, in each of the washing, rinsing, and dewatering processes, the microcomputer 2 determines whether or not the water supply process is in step 7, and if it is the water supply process, opens the water supply valve in step 8 to start water supply.

Next, in step 9, the microcomputer 2 determines whether there is an abnormality in the water supply. If the water level does not reach a certain level even after a certain period of time has elapsed since the start of water supply, a water supply abnormality is displayed in step 1o.

Here, the washing time setting display section 5a displays a plurality of indicator lights blinking and lighting. Next, in step 11, the microcomputer 2 determines whether or not it is a drainage process, and if it is a drainage process, it turns on the drainage magnet in step 12. Next, in step 13, the microcomputer 2 determines whether there is a drainage abnormality. If the water is not completely drained even after a predetermined period of time has passed since you started draining,
In step 14, it is displayed that there is a drainage abnormality. Here, the information is displayed by blinking and lighting a plurality of indicator lights on the rinse setting display section 5b. Next, in step 15, the microcomputer 2 determines whether or not it is a dehydration process, and if it is a dehydration process, it turns on the dehydration motor in step 16. Next, in step 17, the microcomputer 2 determines whether there is an unbalanced state. If unbalanced, step 1
At step 8, unbalance correction, that is, elimination of the unbalanced state is controlled, and at step 19, it is displayed that the unbalanced elimination is being controlled. Here, the information is displayed by blinking and lighting a combination of a plurality of indicator lights in the rinse setting display section 5b and the dehydration time setting display section 5c. Next, in step 20, the microcomputer 2 determines whether the unbalanced state remains even after the unbalance correction, and if it is determined in step 21 that the unbalance correction is not possible, the microcomputer 2 determines in step 22 that the unbalance is abnormal. Display something. Here, the information is displayed by blinking and lighting a plurality of indicator lights in the dehydration time setting display section 5C. If the number of unbalance corrections is still less than the predetermined number in step 21, the process returns to step 18 to correct the unbalance, and in step 19, it is displayed that the unbalance correction is in progress.

Effects of the Invention As described above, according to the present invention, the washing time setting display section, the rinsing setting display section, and the spin-drying time setting display section, which are composed of a plurality of existing indicator lights, are used also as an abnormality display. In addition, by displaying that the resolution of the abnormal state is under control using a combination of the above display parts, it is possible to clearly determine at a glance whether there is an abnormal state, the content of the abnormality, or whether the abnormal state is being resolved. .
