Abstract

PURPOSE: To reduce erroneous jugements between an abnormality in respective actions such as washing, rinsing and dehydrating and a fault of device by changing an abnormal mode for use and a reporting method in the case of a fault when reporting an abnormality during a washing process. CONSTITUTION: Corresponding to a setting signal or the like from an input key 2, a control means 1 composed of a microcomputer or the like drives a load circuit 4 such as motor, feed valve or drain valve through a display device 4 and a driver 5 for washing, rinsing and dehydrating according the procedure of a preset program. An abnormality detecting means 6 detects the state of a washing machine such as opening/closing of a lid and water level and the state of a controller itself such as driver 5 and outputs it to the control means 1. When such an abnormal mode in use occurs, it is reported by sounding a buzzer 7 with short intermittent buzzer sounds A. When the input from the abnormality detecting means shows any fault such as short-circuitting or driver 5, it is reported by sounding the buzzer 7 with buzzer sounds B continued for 10 sec.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a washing machine that automatically washes, rinses, dehydrates, etc. clothes.

2. Description of the Related Art Conventionally, as shown in FIG. 1, a washing machine control device includes a control means 1 for controlling a series of sequential operations such as washing, rinsing, and spin-drying, and a control means 1 for controlling the selection of these washing, rinsing, and spin-drying steps. A display device 3 that displays the settings and progress status of each process, a load circuit 4 such as the washing motor and water supply valve, a driver 5 that drives the load circuit 4, and a driver 5 that detects abnormalities in the washing process and the driver 5. It consisted of an abnormality detection means 6 for detecting a failure, and a buzzer 7° for notifying the user that an abnormality has occurred.

With this configuration, a series of washing, rinsing, and dehydrating steps are performed. During this process, for example, if the lid of the washing machine is opened during the spin-drying process, it will be detected by the abnormality detection means 6 and the buzzer 7 will be alerted by a continuous sound for about 10 seconds as shown in the buzzer sound B in Figure 2. The user was then prompted to close the lid. Furthermore, when the driver 5 fails and the load circuit 4 such as a motor becomes uncontrollable, the buzzer 7 is similarly sounded for about 10 seconds to notify the driver.

Problems to be solved by the invention: ``With such conventional notification methods, the notification method is the same regardless of the abnormality, so the user simply closes the lid, adjusts the twist of the cloth, etc. It is not possible to distinguish between an abnormality in the washing process that just needs to be removed, and an abnormality such as a device failure that requires calling a service person, so the abnormality mode during use may be mistaken for a failure. There were many.

The purpose of the present invention is to solve the above problems,
The aim is to reduce misjudgments by changing the method of reporting abnormalities in washing, rinsing, spin-drying, etc. and device failures.

Means for Solving the Problems In order to achieve the above object, the present invention provides a control means for controlling a series of sequential operations such as washing, rinsing, and dehydration, and a control means for controlling a series of sequential operations such as washing, rinsing, and dehydration, and an abnormal state such as an abnormality in each of the operations or a failure of the device. The system includes an abnormality detection means for detecting the occurrence of an abnormality, and a notification means for notifying an abnormal state, and the notification means changes the notification method depending on whether the abnormal state is an abnormality in operation during use or a failure of the device. This was used as a control device for a washing machine.

Function The above configuration allows the user to distinguish between a case where there is an abnormality in each operation due to the difference in the notification method of the buzzer, or a failure of the device 6, and a failure of the device 6. It is now possible to identify and deal with problems immediately without mistaking them for malfunctions.

EMBODIMENTS Below, the drawings shown as an embodiment of the present invention will be explained.

FIG. 1 is a block diagram of a washing machine control device, and FIG. 2 is a timing chart of a buzzer sound when an abnormality is notified.

In FIG. 1, a control means 1 constituted by a microcomputer or the like performs washing and washing according to a preset program procedure in response to a setting signal from a large oyster 2.
A load circuit 4 such as a motor, a water supply valve, a drain valve, etc. is driven through a display device 4 for water purification, dehydration, etc., and a driver 5.

The abnormality detection means 6 detects the opening/closing of the lid, the state of the washing machine such as the water level, and the state of the control device itself such as the driver 5, and outputs the detected state to the control means 1.

Control means] responds to the input from the abnormality detection means 6, and if an abnormal mode occurs during use, such as opening the lid during dewatering or forgetting to turn down the drain hose, the control means will emit a buzzer sound A for 0.2 seconds in Fig. 2. The buzzer 7 is alerted by a short intermittent tone that is on and off for 0.3 seconds. The user then closes the lid, turns down the drain hose, etc., and removes any abnormalities in the washing process to return it to normal progress.

Further, if the input from the abnormality detection means 6 is a failure such as a short circuit in the driver 5, the buzzer 7 is sounded with a continuous sound of the buzzer sound B in FIG. 2 for 10 seconds to notify the driver. The user will then be able to detect that the washing machine is out of order and will take steps to repair it.

In this embodiment, the notification is made different depending on the operating time of the buzzer, but it may be made different depending on the frequency of the buzzer sound, for example, and it is sufficient if the notification method is different.

Effects of the Invention As described above, according to the present invention, when an abnormality during the washing process is notified, by changing the abnormality mode in use and the notification method in the case of a failure, it is possible to easily distinguish between the two, and the user can easily distinguish between the two. It becomes clear which abnormalities can be dealt with by the operator and which ones require repair or other procedures, which has the effect of eliminating erroneous judgments and allowing appropriate countermeasures to be taken.
