Detailed description of the invention
Below in conjunction with attached flow chart, the washing control method for washing machine providing the present invention is described in detail.
Shown in Figure 1, for the first embodiment of the present invention.After washing machine energising, user can set the water temperature T 1 rushing detergent or detergent by display screen, rushes heating module t preheating time of detergent water inlet.
After washing machine starts, go to main wash into water rush the detergent stage time, first heat according to the power of " rated power/2 " to heating module energising, after 3s, heating module power is gradually increased to rated power, opens I way solenoid valve simultaneously, first open 1/3 aperture, water inlet begins to warm up, and along with heating, water temperature gradually rises, when hot water temperature rushes detergent temperature T1 more than setting, the regulation of I way solenoid valve opens amplitude to realize constant-temperature effluent.
After I way solenoid valve fully opens, when hot water water temperature is more than design temperature T1, II way solenoid valve is opened, first open 1/3 aperture, open amplitude along with after neutralizing the change of water temperature be automatically adjusted, when water temperature is less than design temperature T1 after neutralizing, turn II way solenoid valve aperture down；When water temperature is higher than set water temperature T1 after neutralizing, then tune up II way solenoid valve aperture.
When, after I, II electromagnetic valve all standard-sized sheets, when after neutralization, water temperature rises to " design temperature-2 ° ", the power of regulation heating module power to " rated power/2 " proceeds heating.When water temperature reduces after neutralizing, improve heating power；When water temperature raises after neutralizing, reduce heating power.Realizing constant-temperature effluent by above regulation, water temperature major control is in the range of " positive and negative 2 ° of design temperature ".
For embodiment one, only setting the program rushing detergent temperature T1, master washes t heat time heating time into hot water injection's clothing powder and is set as 2 minutes, stops heating after more than 2 minutes, only opens the water inlet of I way solenoid valve and absorbs the heat that heating module distributes.Stopping 3s before heating, heating module power starts gradually to turn down, to the last Close All.
Shown in Figure 2, for the second embodiment of control method of the present invention.Rushing detergent temperature T1 for both setting, also set the program of wash temperature T2, main washing is set as 2 minutes into hot water injection clothing powder time t, and hot water temperature rushes detergent temperature T1 for set, and heating and the temperature of rushing detergent water inlet control as implemented described in one.
After flooding time was more than 2 minutes, then meet washing water temperature requirement according to wash temperature T2 regulation heating module heating power, I road and the II way solenoid valve aperture set.
When water level of intaking reaches " setting water level-1 gear ", heating module quits work, and only opens the water inlet of I way solenoid valve and absorbs the heat that heating module distributes, until water inlet starts washing to designated water level.When stopping heating, heating module power is gradually lowered to 0 rather than is directly reduced to 0 by high-power.
During for just beginning to warm up, first heat according to the power of " rated power/2 " to heating module energising, after 3s, heating module power is gradually increased to rated power；Stop being then to be gradually lowered by heating power at that time to be 0 rather than directly close during heating.Do so is that of avoiding the most high-power powering on or heavy current impact that high-power power-off causes, protects control circuit and heating module well.
And I road and II way solenoid valve almost all are opened, by regulating the method that heating module power realizes constant temperature, it is achieved that big flow constant temperature water inlet, save flooding time.
See Fig. 3 to Fig. 4, it is shown that the washing machine of the above-mentioned control method for washing of employing of the present invention.Heater in the present invention is loaded on washing machine top, and between water intaking valve and water injection box, both sides are connected with water intaking valve and water injection box by water supply hose.Washing machine includes casing 1, the urceolus 2 containing washings, is sleeved in outer barrel for containing the washing inner core 3 of medicated clothing, water feed apparatus, drainage arrangement, control system, described water feed apparatus includes electromagnetic valve 4, heating module 6, water injection box 8, heating module 6 one end connects electromagnetic valve 4 by water inlet pipe 5, and the other end connects water injection box 8 by outlet pipe 7.In order to multichannel is intake, in the present invention, electromagnetic valve is adopted as three-way valve, heating module 5 includes 9, two water inlets 51,52 of heater, one outlet 7, temperature sensor 10, the I road water inlet pipe of three-way valve is attached can be heated water on the heaters, and II road water inlet pipe enters cold water, I road and II way solenoid valve and uses the direct current generator of adjustable valve aperture respectively, this direct current generator can be automatically adjusted water valve aperture, adjusting water outlet uninterrupted according to water outlet temperature setting.Described temperature sensor 10 be arranged in hot and cold water and after outlet pipeline 7 on, temperature sensor is loaded on bottom water pipe, to ensure also to touch current when current are less, accurately records water temperature.
In washing machine of the present invention, heating module uses variable power control, and heating module power is more than or equal to 1500 watts.
In sum, by using above-mentioned technical scheme, use the washing machine of this control method for washing to have between electromagnetic valve and water injection box and set up heating module, simple and reliable for structure, by programme-control, during water inlet, tap water is heated, improve the usefulness of detergent, thus improve detersive efficiency.
Certainly, the present invention is not limited to the example above, the technical scheme that it will be apparent to those skilled in the art that, without departing from the spirit or scope of the present invention, this technical scheme is the most applicable at impeller-type, drum-type, agitator type washing machine and other similar scrubber, the present invention does various modifications and changes in the range of the claims in the present invention and equivalent thereof, then the present invention contains such modifications and changes.
