JPH03259398A - Abnormality informing device - Google Patents

Abstract

PURPOSE:To improve serviceability and the efficiency of the development of software by storing data representing a stage operation in which abnormality occurs and the kind of abnormality when a control part detects the abnormality, and enabling the information of the data to be fetched at need even after informing the abnormality. CONSTITUTION:Courses from the application of a power source switch 5 to the start of a washing course in a washing machine, etc., such as temporary interruption, a cloth amount measuring course, a washing course, etc., are expressed in course numbers, respectively. Also, a water supply operation, a washing operation, a drainage operation, etc., in the course are expressed in operation numbers, and water supply abnormality, drainage abnormality, etc., in abnormality numbers. Then, all course operations in which the abnormality occur and the kinds of the abnormality are expressed in three digits or characters. When the abnormality occurs, the information of three digits for the abnormality is stored in the memory of a computer 1, and the abnormality is informed. After that, ordinary display is interrupted by depressing a prescribed switch at an operating part 4, and a value stored in the memory is displayed on a display part 3. In such a way, it is possible to quickly find out the cause of the abnormality, and to improve the serviceability and the efficiency in the development of the software.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to control devices for washing machines, dryers, dishwashers, etc., and particularly relates to abnormality display thereof.

[Conventional technology]

As disclosed in Japanese Unexamined Patent Application Publication No. 1-185291, conventional control devices have means for detecting abnormal conditions and distinguishing between abnormalities that can be corrected by the user and abnormalities due to failure, and notifying the user.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the power supply is automatically cut off after detecting an abnormality and notifying the abnormality. - When the power is turned off, the information about the previous abnormality disappears, so if an abnormality occurs at the customer's location, by the time the service person comes to repair, the abnormality notification has already been completed and it is time to investigate the cause of the abnormality. The problem was that it was not easy.

In addition, in debugging work at the software development stage, there is an inconvenience that constant monitoring is required in order to know in which process an abnormality has occurred.

An object of the present invention is to provide a means for knowing the process, operation, and type of abnormality in which an abnormality has occurred even after the abnormality notification is completed, and to improve serviceability and efficiency of software development.

[Means to solve the problem]

In order to achieve the above purpose, we have a control circuit that controls each connected load to perform the processes in sequence, and a display means that displays the process operation, and when an abnormality is detected, it is displayed as the latest abnormality. Data on process operations and types of abnormalities are stored in the memory of a microcomputer, and there is a means for retrieving the information when necessary even after notification of an abnormality.

[Effect]

According to the above configuration, when an abnormality occurs at the customer's location,
Since information about the abnormal process operation and the type of abnormality that occurred before the service person came for repair can be retrieved, the cause of the abnormality can be accurately and quickly determined.

Furthermore, during debugging work in the software development process, the above information can be known without constant monitoring, improving the efficiency of software development.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 shows an example of a control circuit device for a washing machine according to the present invention. 2, and controls the motor M, water supply valve IV, drain valve Mg, power SW cutoff coil A○, etc. In addition, 3 is the display section, which shows the process,
From the light emitting diode that displays the washing course, etc., and the segment display section that displays the clock, remaining time, and alarms by blinking l E j'' as shown in Figure 2 (a) to notify you of an abnormality. Become.

Next, as shown in Fig. 3, each washing process is performed from when the 5 power switch in Fig. 1 is turned on until the washing cycle starts (
Hereinafter, the state (hereinafter referred to as the initial state) is referred to as the process &O, and the stopping state is referred to as the process &1. Cloth amount measurement process &2. The washing process is designated as process NQ3, and all other processes are also represented by process demons.

In addition, the same operation Na as the process demon is added to the order of operations performed in the water supply operation, washing operation, drainage operation, etc. in the process, and the water supply operation in the washing process is performed in the order of operation &1. Washing operation Na
2.

The drainage operation is set to operation N113, and all other operations are set to operation Nα.
Expressed as In addition, regarding the types of abnormalities, water supply abnormalities are expressed as abnormality 1, drainage abnormalities are expressed as abnormality Nα2, and all abnormalities are expressed as abnormality.

From the above, the process operation in which the abnormality has occurred and the type of abnormality can all be expressed by three-digit numbers or letters.

Here, consider a case where a water supply abnormality occurs during the water supply operation in the washing process. As mentioned earlier, if this abnormality is displayed, the process will be shameful 3. Operation NQl, abnormality Nα1.

This information is stored in the memory of the microcomputer as data tL31111. This information is
It is held until a new abnormality occurs or the microcomputer is reset, and is rewritten every time a new abnormality occurs.

The operation unit 4 in Fig. 1 is provided with a plurality of SWs, and the normal display can be changed by pressing a predetermined number of SWs at the same time during the initial state, - time stop state, and regular alarm. There is a temporary interruption, and the value "311" stored in the memory is displayed in segments as shown in FIG. 2C, and continues to be displayed until the SW input is no longer present.

〔Effect of the invention〕

Above, we have described the water supply abnormality that occurred during the water supply operation of the washing process, but the present invention
Since information about abnormalities can be retained, it is very effective in investigating the cause of abnormalities.

According to the present invention, even when the power switch is turned off and turned on again after an abnormality is reported, the process operation in which the previous abnormality occurred and information on the abnormality can be confirmed, making it very easy to find the cause of the abnormality. .

In addition, even during debugging work in the software development process, information on abnormalities that have occurred can be obtained without constant monitoring, improving the efficiency of software development.

In addition to the washing machines of the embodiments, the present invention is also applicable to products that perform similar control and have segment displays, such as dryers and dishwashers.
