Hereinafter, a second embodiment will be described. In the second embodiment, in addition to the configuration of the first embodiment, a use state correction unit 18 shown by a dotted line in FIG. 1 is provided, and the use state correction unit 18 controls the use state of the combustion equipment. A control structure is provided for correcting the corresponding data based on the data corresponding to the frequency of use of the combustion equipment. In addition,
In the description of this embodiment, a duplicate description of parts common to the first embodiment will be omitted.

The data fetching section 16 receives the data fetching command, fetches data corresponding to the use status from the data storage section 21 of the combustion equipment, and also fetches data corresponding to the use frequency (for example, data of the number of times of combustion, data of the burner, (2) data on the amount of combustion heat and data on the fan air volume of the combustion fan), and outputs the captured information to the use condition correction unit 18.

The data storage section 15 is provided in advance with correction data for correcting data corresponding to the use situation based on the data corresponding to the use frequency captured by the data capture section 16. For example, relation data between the data corresponding to the use situation and the reference use frequency is given in advance, and based on the relation data and the use frequency of the taken combustion equipment, the use frequency of the taken combustion equipment is determined. If the frequency of use is higher than the reference frequency according to the data corresponding to the usage status of the combustion equipment, the data corresponding to the usage status is calculated by the amount corresponding to the deviation of the captured usage frequency from the reference usage frequency. If the usage frequency of the captured combustion equipment is less than the usage frequency of the standard, only the amount corresponding to the deviation of the usage frequency from the reference usage frequency is corrected. The data for correcting the data for the usage status in a direction to shorten the usage status is previously given to the data storage unit 15 as the correction data for the usage status.

The use state correction section 18 is based on the data corresponding to the use state and the data corresponding to the use frequency added from the data take-in section 16 and the correction data read from the data storage section 15. , Correction of data corresponding to the above-mentioned use situation.

The display unit 14 displays the life expectancy curve data stored in the data storage unit 15 on the screen of the display 11 and displays the position of the data corresponding to the usage status corrected by the usage status correction unit 18. It is displayed on the life prediction curve data displayed on the screen in the same manner as the display mode shown in the first embodiment.

According to this embodiment, the data corresponding to the use condition is corrected according to the data corresponding to the use frequency of the combustion equipment, and the position of the data corresponding to the corrected use condition is displayed on the screen. Therefore, for example, when the burner 2 is used for a short period of time, but the number of times of combustion is large and the frequency of use is high, the deterioration of each component of the combustion equipment is accelerated. If the correction is made and the use time is long, but the number of times of combustion is small and the use frequency is low, the deterioration of each component of the combustion equipment is slow, so the data corresponding to the use situation will be corrected to decrease. It becomes possible to display the position suitable for the deterioration state of each component of the combustion equipment on the life prediction curve data,
It is possible to objectively indicate the relationship between the state and the life of the combustion device to the user of the combustion device, and it is possible to enhance the reliability of the life prediction of the combustion device.

Of course, the relationship between the data corresponding to the usage status of the combustion equipment and the data corresponding to the usage frequency is almost fixed, and the relationship hardly shifts.
As described above, it is possible to almost accurately show the position suitable for the deterioration state of each component of the combustion equipment on the life prediction curve data without correcting the data corresponding to the use situation with the data corresponding to the use frequency However, as described above, by correcting the data corresponding to the use situation, it is possible to more accurately show the position suitable for the deterioration state of each component member of the combustion apparatus on the life prediction curve data.

It should be noted that the present invention is not limited to the above embodiments, but can take various embodiments. For example, in each of the above embodiments, the life prediction curve data is
The life prediction curve data is formed by a combination of data corresponding to the failure rate related to the initial failure, data corresponding to the failure rate related to the random failure, and data corresponding to the failure rate related to the wear failure. 5 may be formed by a combination of data corresponding to the failure rate related to the wear failure and data corresponding to the failure rate related to the wear failure.
In this case, the data corresponding to the failure rate for the initial failure is not shown, so even if you just purchased the combustion equipment,
It is possible to prevent the user of the combustion device from having a distrust that the user may be out of order at a higher probability than the accidental failure period Tcf.

Further, in the second embodiment, the configuration for correcting the data corresponding to the use status based on the data corresponding to the use frequency of the combustion equipment has been described.
Is provided, and instead of correcting the data corresponding to the usage status, the data correction unit 22 uses the life prediction curve data stored in the data storage unit 15 based on the data corresponding to the use frequency. The corrected life prediction curve data is output to the display unit 14. The display unit 14 displays the corrected life prediction curve data and captures the data on the life prediction curve data displayed on the screen. The position of the data corresponding to the use status captured by the unit 16 may be displayed. In this case, the data fetching unit 16 fetches data corresponding to the usage status from the data storage unit 21 of the combustion device, fetches data corresponding to the usage frequency, and stores the data corresponding to the usage frequency in the data correction unit 22.

It is also possible to select and output the selected life expectancy curve data to the display unit 14. In this case, the display unit 14 displays the life expectancy curve data that matches the model of the combustion device and the frequency of use on a screen. Along with
On the life prediction curve data displayed on the screen, the position of the data corresponding to the use status captured by the data capturing unit 16 is displayed.

As the amount of information on failures used to create the life expectancy curve data increases, the life expectancy curve data becomes more suited to the actual situation, and more accurate life expectancy curve data can be shown.

In the case where the life prediction curve data is stored in the information recording medium, information on the failure of the combustion equipment is accumulated, and the information is sequentially created and stored in the information recording medium as the information on the failure of the combustion equipment increases. Since the life prediction curve data obtained can be used, the life prediction curve data becomes data more suitable for the actual situation as the amount of information on the failure used to create the life prediction curve data increases, and a more accurate life It is possible to show the prediction curve data.

In the apparatus having a configuration for printing and displaying the life prediction curve data indicating the position of the data corresponding to the use situation, the life prediction curve data indicating the position of the data corresponding to the use state is provided. Can be given to the user of the combustion equipment as reference data when considering replacement of the combustion equipment.
