As mentioned above, the invention detects or calculates the dirt degree caused by each time of washing, when washing once, the more dirty the washed clothes are, the larger the turbidity of the washing water in the washing process is, the larger the average turbidity y or the turbidity correction coefficient y is, and meanwhile, the longer the washing time t is, the larger the dirt degree of the tub caused by the longer the washing time t is, the larger the value of the dirt degree obtained by calculation or detection is; the cleaner the washed clothes are, the smaller the average washing water is in the washing process, the smaller the average turbidity y or the turbidity correction coefficient y is, and meanwhile, the shorter the washing time t is, the smaller the dirt degree of the barrel caused by the smaller the average washing water is, and the smaller the dirt degree value obtained by calculation or detection is; that is, the degree of soiling of the tub is directly related to the degree of soiling of the laundry being washed, and the degree of soiling thus calculated or detected has a high degree of accuracy, and it is determined whether it is necessary to remind the user of the tub cleaning of the washing machine by determining whether the total degree of soiling K of the tub reaches or exceeds the critical value Kmax.
As a preferred embodiment of the present invention, if the washing temperature of the washing machine is adjustable, the degree of contamination k = T x of the tub caused by each washing, where T is the washing time, y is the average turbidity of the washing water during the washing process or a turbidity correction coefficient corresponding to the turbidity of the washing water during the washing process, and x is a temperature correction coefficient corresponding to the average water temperature T during the washing process.
Specifically, the temperature deviation correction coefficient x is determined according to the influence of the average water temperature T in the washing process on the bacterial reproduction; since the washing temperature has a large influence on the propagation and production of bacteria, the temperature deviation correction coefficient x is increased when calculating the k value.
Further, the critical value Kmax comprises a plurality of gradually increasing values Kmax1, Kmax2, Kmax3, … … and KmaxN; when K is larger than or equal to Kmax1, the washing machine sends out a first prompt signal; when K is larger than or equal to Kmax2, the washing machine sends out a second prompt signal; … …, respectively; when K is larger than or equal to KmaxN, the washing machine sends out an Nth prompt signal; therefore, when the user gives a signal at the washing machine that the washing machine is not washed, the total contamination degree K is further cumulatively calculated, and when K reaches the next critical value Kmax, the washing machine gives a prompt signal again. The threshold value Kmax is a value set by a user, or the threshold value Kmax is a factory preset value of the washing machine.
On the basis, in the step c of the invention, the total washing time tmax = t1+ t2+ t3+ t4+ … … + tn is set, and when the total washing time tmax is equal to or more than the selected time, the washing machine sends out a prompt signal to remind a user to clean the washing machine barrel; wherein t1 is the washing time of the first washing, t2 is the washing time of the second washing, t3 is the washing time of the third washing, t4 is the washing time of the fourth washing, … …, tn is the washing time of the nth washing.
In the invention, when the total washing time tmax reaches or is greater than the selected time, namely the total dirty degree value K of the toilet bowl does not reach or is greater than the critical value Kmax, the washing machine also sends a prompt signal to remind a user to clean the washing machine barrel, so that the regular reminding is realized, the user is reminded to clean the washing machine barrel regularly, and the bacteria breeding caused by the fact that a small amount of residual dirty matters are adhered to the washing machine barrel for a long time is avoided; that is, the washing machine judging method can periodically remind the user of washing the washing machine tub, and the specific reminding time limit is determined by the selected time set by the user.
In the invention, the selected time set by a user is taken as a period, if the total dirt degree K of the barrel reaches or is more than Kmax in the period, the washing machine sends out a reminding signal, the user cleans the washing machine barrel after receiving the reminding signal, the period is ended, the washing machine barrel enters the next period after being cleaned, namely the total dirt degree K of the barrel returns to zero, and the selected time starts from zero and restarts to calculate the dirt degree K value of the barrel; if the total dirt degree K of the barrel does not reach or exceed Kmax in the period, the washing machine sends out a reminding signal after the last washing in the period, the user cleans the washing machine barrel after receiving the reminding, the period is ended, the next period is entered after the washing machine barrel is cleaned, namely the total dirt degree K of the barrel returns to zero, and the selected time starts from zero and starts to calculate the dirt degree K value of the barrel again.
Further, the washing time t is obtained by a washing mode selected by the user; according to the operating principle of the washing machine, after the user selects the washing mode, the specific washing time in the washing mode is determined, so that the washing time t can be directly obtained through the washing mode selected by the user.
In the invention, the average turbidity y or the turbidity correction coefficient y is obtained by detecting a turbidity sensor arranged in a washing machine barrel; as an alternative embodiment, the average turbidity y or the turbidity correction coefficient y may be detected by a turbidity sensor provided in the drain valve of the washing machine.
Preferably, the total dirt degree K is transmitted to the mobile terminal or the display panel of the washing machine through the information output structure, so that the user can know the dirt degree of the washing machine in time.
Specifically, referring to fig. 1, when a user uses the washing machine, if the user selects a tub/drum cleaning program, the user calls a dirt value K accumulated in a last washing time interval, then determines the tub/drum cleaning program according to the value K, the washing machine executes the tub/drum cleaning program, and the washing is completed to finish the whole program; if the user does not select the barrel/barrel cleaning program, if the accumulated dirt value K does not reach the preset value Kmax, the accumulation is continued, if the accumulated dirt value K reaches the preset value Kmax, the washing machine sends out a reminding signal, namely a reminding instruction for feeding back the barrel/barrel cleaning is fed back, at the moment, if the user confirms the barrel/barrel cleaning program, the washing machine executes the barrel/barrel cleaning program, and the whole program is finished after the cleaning is finished.
It should be understood that the above embodiments are only examples for clearly illustrating the present invention, and are not intended to limit the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
