Abstract

PURPOSE:To allow summing up of all the contents of failures to a computer without troubles even if the power supply is cut off by providing a memory device that holds the contents of failures detected even in a power failure, and a connecting device that transmits the stored contents of failures to the computer. CONSTITUTION:The power is supplied to a combustion controller 3 and a failure detecting unit 4 through a plug socket and a power source unit 2. The failure detecting unit is composed of a failure detecting device 5, a memory device 6 for the detected contents of failures, an annuncicator 7 to display the contents of failures, a back-up power source 8 to hold the contents of failures stored when the plug socket is pulled out, a computer connecting device 10 to transmit the contents of failures stored to a sum-up computer 9. By this constitution described above, the contents of failure can be held even if the plug socket is pulled out, and all the contents of failures can be summed up to the sum-up computer without troubles.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a failure detection device for storing failure details of combustion appliances.

Conventional technology Conventional failure detection devices help combustion appliance service personnel diagnose failures by detecting failures using the self-diagnosis function of combustion appliances, displaying the details of the failures, and clearly indicating the location of the failure. Met.

Problems to be Solved by the Invention However, in the conventional configuration, a large number of combustion appliances are used in order to investigate the occurrence of failures in combustion appliances and find out what types of failures are common and how often they occur. Collect details of failures. In this case, when the service person goes for service, he or she has no choice but to collect sheets of paper recording the details of the failure displayed, which is time-consuming. In addition, in order to reuse the combustion appliance after a failure occurs (if the user turns on the combustion appliance again, the history of failure occurrence will be erased, so it is not possible to tally up all the failure details that have occurred). There was a problem.

In order to solve the above-mentioned problems, the present invention aims to compile all failure details of combustion appliances without much effort.

Means for Solving the Problems In order to solve the above problems, the failure detection device of the present invention includes:
A device comprising a failure detection means for detecting a failure of the combustion appliance, a storage means for storing the details of the failure even if the power to the combustion appliance is cut off, and a computer connection means for connecting to a computer and transmitting the contents of the failure to the computer. It is.

According to the above-described configuration, the present invention inputs the details of the failure of the combustion appliance detected by the failure detection means into the storage means that retains the contents even if the power source of the combustion appliance is cut off, and inputs the failure contents by the computer connection means. By transmitting the information to the computer, all failure details can be compiled into the computer without any effort even after the power is shut off.

Example Embodiments of the present invention will be described below based on the drawings.

The figure is a system configuration diagram of a failure detection device according to an embodiment of the present invention, in which 1 is a power outlet for a combustion appliance, and 2 is a power supply device, which supplies power to a combustion appliance control device 3 and a failure detection device 4. The failure detection device 4 includes a failure detection means 5 for detecting a failure, a storage means 6 for storing the contents of the failure detected by the failure detection means 5, a display means 7 for displaying the contents of the failure, and a power outlet 1 that is unplugged. Memory means 6
A bank-up power supply 8 for holding the failure details stored in the memory means 6 and a bank-up power supply 8 for holding the failure details stored in the storage means 6.
A computer connecting means 10 for transmitting information to the totalizing computer 9 is provided.

The operation of the failure detection device configured as described above will be described below.

When the failure detection means 5 detects a failure while the combustion appliance is in use,
The signal is transmitted to the combustion appliance control device 3 to operate the safety function, and the detected failure details are transmitted to the storage means 6 and the failure contents are stored in the storage means 6. On the other hand, display means 7
By displaying the details of the failure according to the contents stored in the storage means 6 and clearly indicating the location of the failure, it is possible to shorten the time for failure repair and to perform appropriate failure diagnosis.

Here, if the user turns on the power outlet 1 when a failure occurs, even if power is no longer supplied to the failure detection device 4, the contents stored in the storage means 6 are retained by the backup power supply 8, and the power is turned on again. When supplied, the display means 7 can display the details of the failure that has occurred.

Further, by connecting the computer connecting means 10 to the totalizing computer 9, the details of the failure stored in the storage means 6 can be transmitted to the totalizing computer 9.

As described above, according to this embodiment, by providing the storage means 6 for storing the details of the failure and the backup power source 8 for retaining the stored contents of the storage means 6 when the power supply is cut off, the power outlet 1 can be unplugged. Even if the problem occurs, the details of the failure can be retained.

Furthermore, by providing the computer connection means 10,
Computer 9 for tabulating all failure details without any effort
can be aggregated into

Effects of the Invention As described above, the present invention provides a storage means that retains the details of the detected fault even when the power is cut off, and a computer connection means that transmits the fault details stored in the storage means to the computer. Therefore, even if the power is cut off,
All failure details can be compiled on a computer without much effort.
