JPH024125A - Failure memory device for combustion apparatus - Google Patents

Abstract

PURPOSE:To allow a failure memory device to be mounted on another apparatus for using it repeatedly by providing a non-volatile memory that stores the contents of failures of an apparatus, an erasing device that erases the memory stored, and an attaching and detaching device that allows the failure memory device to be attached and detached. CONSTITUTION:When detecting a failure of an apparatus, a failure detecting device 2 transmits a signal corresponding to the contents of the failure to a combustion controller 1, and the contents of the failure is written to a non-volatile memory 3 by a writing device 1a. When a switch 9 is pressed to display the contents of the failure written, the combustion controller reads the contents of the failure from the non-voltaile memory by a reading device, and transmits the contents of failure to a failure content annunciator to display the contents of the failure. When a switch 5 is pressed, an erasing device 4 erases all the contents of failures stored in the non- volatile memory. A connector is a device that allows the failure memory device to be freely attached and detached to and from an apparatus. Thereby, even if reset of power source occurs, the contents of failures can be retained. And as the memory can be erased if unnecessary, the device is dismounted and mounted on another apparatus to use it repeatedly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fault memory device for combustion appliances.

BACKGROUND OF THE INVENTION In general, combustion appliances are equipped with a fault storage device that uses a self-diagnosis function to detect a fault when a fault occurs, and stores and displays the details of the detected fault.

Problems to be Solved by the Invention However, in the conventional configuration, the faulty storage device could not be removed from the appliance, so the faulty storage device that was no longer in use could not be attached to another appliance and used repeatedly. Furthermore, since volatile memory is used to store the details of the failure, if an action such as resetting the power to the combustion appliance occurs, all the stored details of the failure are lost.

In order to solve the above problems, the present invention memorizes and retains the details of the failure even if an operation such as power reset of the combustion appliance occurs,
The purpose of the present invention is to provide a failure storage device whose stored contents can be erased, and which can be removed and attached to other equipment for repeated use.

Means for Solving the Problems In order to solve the above problems, the failure storage device of the present invention includes:
It has a non-volatile memory for storing the failure contents of the appliance, and an erasing means for erasing the failure contents stored in the non-volatile memory, and is removable and can be attached to another appliance,
It has a structure that can be used repeatedly.

Function The present invention, with the above-described configuration, retains the failure details of the appliance even if an operation such as a power reset occurs, and the memorized contents can be erased, so when it is no longer needed, it can be removed and attached to another appliance. At this time, if you erase the memory, you can use it repeatedly.

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, reference numeral 1 denotes a control device for a combustion appliance, which has a means 1a for writing fault details into a nonvolatile memory 3 and a means 1b for reading fault details. 2 is a failure detection device, 4 is an erasing means for erasing the failure contents stored in the nonvolatile memory 3, and 5 is a switch. The nonvolatile memory 3, erasing means 4, and switch 5 constitute a failure storage device 6. 7 detachably connects the failure storage device 6 to the instrument.The operation thereof will be explained below.

When the failure detection device 2 detects a failure in an appliance, it outputs a signal to the combustion appliance control device 1 in accordance with the detected failure details.

The combustion appliance control device 1 writes the failure details outputted from the failure detection device 2 into the nonvolatile memory 3 using the failure details writing means 1a. The switch 9 is a switch for displaying the contents written in the nonvolatile memory 3 on the failure display means date, and each time the switch 9 is pressed, the combustion appliance control device 1 reads the failure contents reading means 1b from the nonvolatile memory 3. The details of the failure are read out and outputted to the failure details display means 8. The failure details display means 8 displays the details of the failure in accordance with the output signal from the combustion appliance control device 1. The switch 5 is a switch for erasing the fault content data stored in the nonvolatile memory 3. When the switch 5 is pressed, the erasing means 4 erases the fault content data stored and held in the nonvolatile memory 3. All of them are gone.

As described above, according to this embodiment, the failure storage device 6 is removable from the connector 7, so when it becomes unnecessary,
It can be used repeatedly by removing the fault memory device 6 from the connector 7, attaching it to another appliance, pressing the switch 5, and erasing all the fault contents stored and held in the nonvolatile memory 3 by the erasing means 4. Furthermore, the failure details at the time of failure can be easily known through the failure details display means 8, and by repeatedly pressing the switch 9, it is also possible to know the contents of previous failures, making it possible to appropriately determine the cause of the failure. .

As seen from the effects of the invention, the present invention includes a non-volatile memory for storing and retaining the contents of a malfunction of the device, a means for erasing the contents stored in this memory, and a detachable means for making the device removable. When it is no longer needed, it can be removed and attached to another device, and at this time, by erasing the memory,
It can provide the convenience of being able to be used repeatedly.
