Abstract

PURPOSE:To enable order of the failure occurrence and the sequential relationship between failures to be provided by storing the contents of failures and the order of failure occurrence of an apparatus to display the stored failure contents and occurrence orders. CONSTITUTION:When detecting a failure, a failure detecting unit 1 outputs a signal corresponding to the content of the failure to a failure annunciating controller 2. The failure annunciating controller writes the content of the failure to a failure content memory device 4 and simultaneously the data on the failure occurrence order are written to a failure occurrence order memory device. A switch 6 is a change-over switch by which the contents written to the failure content memory device and the failure occurrence order memory device are displayed on a failure content/occurrence order annunciator 5. Every time the switch 6 is pressed, the failure content annunciating controller reads out the contents of failures from the failure content memory device, and the failure occurrence order from the failure occurrence order memory device respectively, and outputs signals to the failure content/occurrence order annunciator 5. The failure content/occurrence order annunciator 5 displays the contents of failures and the failure occurrence order according to the input signals.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a failure indicating device for combustion appliances and the like.

BACKGROUND ART In general, failure display devices for combustion appliances are provided with means for storing only the details of the failure of the appliance and means for displaying the stored details of the failure.

Problems to be Solved by the Invention However, in the conventional configuration, only the details of the failure were stored and displayed, so it was impossible to find out the order in which the details of the failure occurred or the relationship between the contents before and after the contents of the failure.

In order to solve the above-mentioned problems, the present invention stores not only the failure details of appliances but also the order of failure occurrence, displays the failure contents and the order of failure occurrence, and displays the relationship between the order of occurrence of the failure contents and the failure contents before and after. The purpose is to enable you to find.

Means for Solving the Problems 5 In order to solve the above problems, the fault display device of the present invention includes a fault content storage means for storing the details of the failure of the appliance, and a fault occurrence means for storing the order in which the fault contents occurred. The apparatus includes a sequence storage means and a failure contents/occurrence order display means for displaying the failure contents and the order of failure occurrence.

Effect of the Invention With the above-described configuration, the present invention stores the failure details and the order of failure occurrence of the appliance, and displays the stored failure details and the order of failure occurrence, thereby determining the relationship between the order of occurrence of the failure contents and the failure contents. It also makes it possible to give

EXAMPLE An example of the present invention will be described below with reference to the drawings.

The figure is a configuration diagram showing an embodiment of the present invention. In the figure, 1 is a failure detection device, 2 is a failure display control means, 3 is a failure content storage means, 4 is a failure occurrence order storage means, 5 is a failure content/occurrence order display device, and 6 is a switch.

When the failure detection device 1 detects a failure, it outputs a signal corresponding to the detected failure details to the failure display device control means 2. The failure display device control means 2 writes the failure details outputted from the failure detection means 1 into the failure contents storage means 3, and also writes data on the order of failure occurrence into the failure order storage means 4. The switch 6 is a changeover switch for displaying the contents written in the failure contents storage means 3 and the failure occurrence order storage means 4 on the failure contents/occurrence order display device 5. Each time the switch 6 is pressed, the failure display device The control means 2 reads the failure contents from the failure contents storage means 3 and the failure occurrence order from the failure occurrence order storage means 4, and outputs the failure contents to the failure contents/occurrence order display device 5. The failure content/occurrence order display device 5 displays the failure details and failure order in accordance with the output signal from the failure display device control means 2.

Effects of the Invention As described above, the present invention stores the failure details and the order of failure occurrence of the appliance, and displays the stored failure details and the order of failure occurrence, thereby establishing the relationship between the order of occurrence of the failure contents and the failure contents. It can also give sex.
