Below, illustrate with reference to Fig. 8 and Fig. 9 the concrete running of feedwater when unusual takes place.
When laundry facilities 1 generation feedwater was unusual, laundry facilities control part 22 sent error codes " E5 ".At this moment, the display part 29a and 10 of laundry facilities 1 and server 8 shown in Fig. 9 (a), shows " it is unusual that feedwater takes place " (step S1, S2, step T1) respectively.
Host computer control portion 5 receives error code " E5 " from server 8, promptly according to the pairing repair message of error code " E5 " (consulting Fig. 8), from the many pairing accident analysis test programs of trouble location of number of packages take place, send (step R1, R2) successively.That is, feed water when unusual, send " hose forget open ", " sneaking into rubbish in the water-supply valve ", the accident analysis test program " E5-T1 " of " water-supply valve fault ", " E5-T2 ", " E5-T3 " successively.
So the display part 29a and 10 of laundry facilities 1 and server 8 shown in Fig. 9 (b), shows " checking water supply system " (step T3, S3) respectively.Laundry facilities control part 22 receives the accident analysis test program of water supply system by server 8 from main frame 4, promptly carries out test run (step S4, S5), and by server 8 this test result is sent to main frame 4 (step S7, T6).Then, main frame 4 is judged trouble location (step R3, R4) according to test result.At this moment, the display part 29a and 10 of laundry facilities 1 and server 8 by shown in Fig. 9 (c), shows " carrying out the water supply system accident analysis " (step S6, T5) respectively.
For example, under the situation of test program " E5-T1 ", laundry facilities control part portion 22 carries out the detection running whether water is arranged in the water hose 43 that anhydrous detecting sensor 34 is arranged, and by server 8 this testing result is sent to main frame 4.Detect when not having water in the water hose 43, host computer control portion 5 is judged to be hose 33 and forgets and open ("Yes" among the step R4).When detecting water hose 43 water being arranged,, be judged as and judge trouble location ("No" among the step R4), thereby return step R2, send next test program " E5-T2 " because hose 33 is open.
Under the situation of test program " E5-T2 ", laundry facilities control part 22 is carried out the flow detection of flow sensor 35, and by server 8 this testing result is sent to main frame 4.Detect flow when setting is following, host computer control portion 5 is judged to be and sneaks into rubbish ("Yes" among the step R4) in the water-supply valve.Detect flow when setting is above, host computer control portion 5 is judged as can not judge trouble location ("No" among the step R4), and returns step R2, sends next test program " E5-T3 ".
Under the situation of test program " E5-T3 ", host computer control portion 5 makes laundry facilities control part 22 carry out flow chart shown in Figure 10.The peripheral part that among Figure 11 the electrical structure of laundry facilities is extracted washing water-supply valve 24 illustrates.Now consult the flow chart that this Figure 11 illustrates Figure 10.At first, laundry facilities control part 22 makes the bidirectional triode thyristor 23a as the drive circuit of water-supply valve 24 end (step P1), and judges at this moment whether the voltage between V1～V2 equals 100V (step P2).When being not equal to 100V ("No"), the connector (not shown) that is judged as the lead unit of water-supply valve 24 faults or water-supply valve 24 come off (step P3).When the voltage between V1～V2 equals 100V ("Yes" among the step P2).Bidirectional triode thyristor 23 conductings (step P4) judge whether the voltage between V1～V2 is 0V (step P5).When being 0V ("Yes" among the figure), be judged as water-supply valve fault (step P6).When being not 0V ("No" among the figure), be judged as laundry facilities control part 22 not at normal operation (step P7).
At this moment, the test result that sends to host computer control portion 5 from laundry facilities control part 22 by server is the voltage between V1～V2, and host computer control portion 5 carries out anomaly analysis according to this voltage.

Therefore, in order to impel the user that washing agent is put into submissive dressing agent storage chamber 41b, to wash running, show at the display part 10 and the 29a of server 8 and laundry facilities 1 in " switch to and restore running ", show that " can not use softener " is to arouse attention.Thus, the user can know and can not use softener.
According to present embodiment, unusual if laundry facilities 1 takes place, promptly analyze this unusual content, infer trouble location, under the treatable situation of anomaly source user itself, show the information of this situation.Therefore, the user watches the demonstration of display part 10 or 29a, can suitably handle.Can not handle anomaly source user itself, need to show the information of this situation under attendant's situation that visit is repaired to the doorstep, carry out inferring result's emergent washing running simultaneously based on it.Therefore, can exempt repair before finishing during can not wash the inconvenience of running.
Especially the global data base 6 that has according to main frame 4 is stored the repair message that keeps, and the emergency operation based on analysis result is carried out at the analysis of failure position, thereby can meet the emergency operation of unusual occurrence cause.
According to present embodiment, owing to entrust service centre to repair automatically, the user is as long as wait for that service centre gets in touch with.
In the above-mentioned example, illustrated that unusual situation takes place washing water-supply valve 24, but the softener valve takes place also can carry out roughly the same emergency operation when unusual.
When break down in the position beyond washing feedwater 24 and the softener valve 25, can carry out following emergency operation.
That is, analyze to level sensor 31 and take place to switch to the emergency operation that control feedwater running and draining operate the time when unusual.In this case, laundry facilities control part 22 can be provided with the storage means such as nonvolatile memory of storage feedwater flow and drain discharge, and according to feedwater flow and drain discharge that these storage means are stored, sets feedwater time and water discharge time.When level sensor shown in Figure 12 31 breaks down, the display frame of display part 10 and 29a in server 8 and the laundry facilities 1.(a)～(e) among Figure 12 in the display frame of (a)～(e) the difference corresponding diagram 9.
Be judged to be cover switch detecting sensor 36 and suspension bracket 39 when breaking down, the speed setting of the motor 21 in the time of can be with the dehydration running gets low than usual, or only forbids the dehydration running in the washing process.
When heater 28 breaks down, switch to heater 28 cold emergency operations.
In the foregoing description, when the accident analysis result distinguishes the fault that the user can not handle, always get in touch with service centre, for example on the display of server, show the picture of selecting " whether getting in touch with service centre " but also can make, when only selecting " contact service centre " the user, get in touch with service centre.
Utilize such formation, when the user did not wish that the attendant visits to the doorstep, for example laundry facilities broke down and does not repair and when considering buy to change, just the inconvenience that does not exist the attendant to bring to the doorstep.
The display part of more than making server and laundry facilities only shows sentence, shows sentence and corresponding pattern thereof but also can make.Make like this, then visually can discern displaying contents.
