The specific embodiment
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Washing machine degerming method provided by the invention, its by control in the silver ion solution the water yield and the concentration of silver ion, thereby effectively reduce consumption and the cost of silver degerming the time.
Washing machine degerming method provided by the invention is independent of washing and degerming is carried out in rinsing separately, i.e. its main degerming step washing finish back and rinsing begin before independent degerming, or after rinsing, carry out degerming separately.Degerming method provided by the invention obtains flooding time earlier, water flowing and electrolytic silver separately in the washing machine then, separately water flowing is so that the water consumption during degerming all lack during than washing and rinsing, and its water flowing time during by the control degerming is no more than 4/5 consumption with realization minimizing water of the shortest flooding time in washing and the rinsing.Make silver ion reach predetermined concentration of silver ions by the washing machine internal controller in conjunction with the amount of programme-control electrolytic silver, fixedly the time, water is more few in the required concentration range of silver ion, and then required silver ion is more few,
Degerming method of the present invention is elaborated as follows in conjunction with the following examples:
No matter be rotary drum washing machine or barrel roll laundry machine, it is provided with entering water electromagnetic valve, level sensor, Computerized controller (hereinafter to be referred as controller), and parts such as silver ion generator.In the present embodiment, it carries out degerming (can be after the rinsing or after the secondary rinsing or after three rinsings, also can be between washing and rinsing, after the preferred last rinsing) after rinsing is finished.
In conjunction with the schematic flow sheet of Fig. 1, at first, the flooding time when controller control detects washing and/or rinsing, when main degerming step is between washing and rinsing, flooding time when detecting washing, then this flooding time is the shortest flooding time T1, simultaneously with its storage; When degerming is after rinsing, detect the flooding time of washing and rinsing, and will wash and rinsing in the shortest the shortest flooding time of time conduct, and with its storage, perhaps only detect the flooding time of rinsing, then the rinsing time is the shortest flooding time, and with its storage.Enter main degerming step then: this main degerming step the washing and rinsing between or after rinsing, carry out separately, during main degerming, opened with water flowing in washing machine by washing machine controller control entering water electromagnetic valve, the time T 2 of water flowing is no more than 4/5 of the shortest flooding time T1.Be that water flowing time T 2 is littler than the shortest flooding time T1 in washing and the rinsing so that during degerming inflow than wash and during rinsing inflow all lack.Preferably, the water flowing time T 2 of described degerming is the 1/5-2/3 of described flooding time T1.
Since washing machine can weigh automatically with according to clothing how much select the washing or the needed water yield of rinsing, level sensor detects the needed water yield when realizing washing with rinsing then, but the water yield required for the present invention is all lacked than washing and the water during rinsing, level sensor self has in the water level true defective of prohibited data detection more after a little while, if so only detect control required water yield during degerming by level sensor when degerming, then error is bigger.Because in the short time, hydraulic pressure and hose are less to the water inlet speed influence of washing machine, thus the flooding time of the present invention during according to the washing before the main degerming or rinsing required inflow when controlling degerming accurately, with the further accurate consumption of control silver.More preferably, the water flowing time T 2 of described degerming is 1/3 of described flooding time T1.
The present invention realizes a certain amount of silver of electrolysis by controller control after water flowing, i.e. controller control electrolysis makes silver ion reach predetermined concentration of silver ions, is in suitable concentration to guarantee silver ion.Preferably, electrolytic silver is to begin electrolysis after described water flowing is carried out 0.5 second, saving time and to guarantee effective electrolytic silver, and economizes silver.A certain amount of silver ion of above-mentioned realization electrolysis, the voltage in the time of can passing through to change electrolysis and/or the time of electrolysis.Preferably, the electrolysis time of electrolytic silver is fixedly the time, and the speed of water flowing is more big, and the voltage of electrolytic silver is more big; When the decomposition voltage of electrolytic silver fixedly the time, the speed of water flowing is more big, and electrolysis time is more long.When for example electrolysis time was fixed as 0.5s, decomposition voltage VT concerned that with the speed rate that is directly proportional of water flowing when being 0.3L/s as water inlet speed, VT is 15V, and when water inlet speed was 0.15L/s, VT was 7.5V.When water inlet speed when too low, also can take the higher relatively decomposition voltage fixed, and reduce electrolysis time.Reach according to program herein that predetermined concentration range is well known to those skilled in the art, do not repeat them here.
Further, degerming method of the present invention also is included in the degerming process clothing is stirred, and describedly carry out when being stirred in electrolytic silver and/or after electrolytic silver is intact, carry out, so that clothing fully contacts with silver ion, thus better degerming.Preferably, method provided by the invention also comprises photodynamic silver sterilizing, more preferably, described photodynamic silver sterilizing be when electrolytic silver or in the intact back of electrolytic silver to washing machine internal radiation ultraviolet ray to realize photodynamic silver sterilizing.
Behind the water yield that the washing machine acquisition is suitable and the suitable silver ionized water, controller can also be controlled the motor periodic duty, as just changeing counter-rotating in 2 seconds 2 seconds, allows silver ionized water fully soak into clothes, soaks then 2 minutes, and draining also dries clothes.
In a word, washing machine degerming method provided by the invention is by independent degerming, with the less water yield, and controls the water yield by the water flowing time and also avoided level sensor to detect inaccurate drawback when water level is low during the control degerming, thereby reduce silver-colored consumption.The water consumption of how many next adjustable minimizing degerming of clothing when it has realized according to laundry, thus when the control concentration of silver ions reaches the required concentration of degerming, reduced silver-colored consumption, reduce cost and also guaranteed effective bacteria-eliminating efficacy.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
