Abstract

A maintenance-information providing system is configured to provide information to maintain an air conditioner more appropriately. The system has an actual trouble code data storage section which stores data based on a trouble code, an actual predictive trouble code data storage section which stores data based on a predictive trouble code, a code-correspondence data storage section which stores a trouble code corresponding to a predictive trouble code and a maintenance-portion-information outputting section. The maintenance-portion-information outputting section extracts a trouble portion of the air conditioner corresponding to the predictive trouble code based on the data of the actual trouble code data storage section and the actual predictive trouble code data storage section. At the same time, the trouble code corresponding to the predictive trouble code is extracted and then a trouble portion of the air conditioner corresponding to the trouble code is extracted.

Claims

1. A maintenance-information providing system for providing maintenance information of an apparatus, comprising:

a storage unit configured to store storage data including trouble data of the apparatus and predictive trouble data of the apparatus, the storage unit including

an actual trouble data storage section configured to store correspondence between the trouble data and the trouble portion in the apparatus that has previously occurred,

an actual predictive trouble data storage section configured to store correspondence between the predictive trouble data and the trouble portion in the apparatus that has previously occurred, and

a corresponding data storage section configured to store the trouble data corresponding to the predictive trouble data; and

a processing unit configured to extract a trouble portion of the apparatus corresponding to the predictive trouble data, based on the storage data of the storage unit, and to extract the trouble data corresponding to the predictive trouble data from the corresponding data storage section and then extracts the trouble portion of the apparatus corresponding to the trouble data.

2. The maintenance-information providing system according to claim 1, wherein

the processing unit is further configured to extract the trouble portion of the apparatus corresponding to the trouble data from the actual trouble data storage section.

3. The maintenance-information providing system according to claim 1, wherein

the processing unit is further configured to output the trouble portion that was extracted as a maintenance portion.

4. The maintenance-information providing system according to claim 1, wherein

the processing unit is further configured to output information on an article used for maintenance of the apparatus.

5. The maintenance-information providing system according to claim 1, wherein

the processing unit is further configured to extract a plurality of the trouble portions,

the processing unit is further configured to calculate a frequency of each of the trouble portions, which are extracted from the actual predictive trouble data storage section and the actual trouble data storage section, and

the processing unit is further configured to output the trouble portion with certainty degrees in descending order of the certainty degrees.

6. The maintenance-information providing system according to claim 1, further comprising

a communication unit configured to receive the trouble data, the predictive trouble data and selected particulars of the apparatus including at least data indicative of a model of the apparatus, wherein

the processing unit is further configured to limit extraction of the trouble portion which meets the particulars.

7. The maintenance-information providing system according to claim 6, wherein

the particulars further include data indicative of an age of the apparatus.

8. The maintenance-information providing system according to claim 6, wherein

the particulars further include data indicative of a business type, and data indicative of an area where the apparatus is located.

9. The maintenance-information providing system according to claim 7, wherein

the particulars further include data indicative of a business type, and data indicative of an area where the apparatus is located.
