Part shown in the figure is: 1. casing, 2. urceolus, 3. inner core, 4. electromagnetic valve, 5. heating module, 6. water injection box, 7. outlet pipe, 8. water injection box, 9. heater, 10. temperature sensor.
The specific embodiment
Below in conjunction with attaching flow chart, washing control method for washing machine provided by the invention is elaborated.
Referring to shown in Figure 1, be the first embodiment of the present invention.After the washing machine energising, the user can set the water temperature T 1 towards washing powder or washing agent through display screen, towards heating module t preheating time of washing powder water inlet.
After washing machine starts, implement and mainly wash into that water, heats to the power of heating module energising according to " rated power/2 " earlier during the stage towards washing powder; Behind the 3s heating module power is brought up to rated power gradually, open the I way solenoid valve simultaneously, open 1/3 aperture earlier; Water inlet begins heating, and along with heating, water temperature raises gradually; When the hot water temperature when setting towards washing powder temperature T 1, the I way solenoid valve is regulated the amplitude of opening to realize constant-temperature effluent.
After the I way solenoid valve was opened fully, the hot water water temperature was during greater than design temperature T1, and the II way solenoid valve is opened; Open 1/3 aperture earlier; The amplitude of opening when neutralization back water temperature is lower than design temperature T1, is turned II way solenoid valve aperture along with the variation of neutralization back water temperature is regulated automatically down; When neutralization back water temperature is higher than set water temperature T1, then transfer big II way solenoid valve aperture.
When I, II electromagnetic valve all behind the standard-sized sheet, when neutralization back water temperature rises to " design temperature-2 ° ", regulate heating module power and proceed to heat to the power of " rated power/2 ".When neutralization back water temperature reduces, improve heating power; When neutralization back water temperature raises, reduce heating power.Through realizing constant-temperature effluent with adjusted, the water temperature major control is in the scope of " positive and negative 2 ° of design temperature ".
For embodiment one, only set towards the program of washing powder temperature T 1, main wash into that t heat time heating time of hot water injection's clothing powder is set at 2 minutes, after greater than 2 minutes, stop heating, only open the water inlet of I way solenoid valve and absorb the heat that heating module distributes and get final product.Stop to heat preceding 3s, heating module power begins to turn down gradually, to the last Close All.
Referring to shown in Figure 2, be second embodiment of control method of the present invention.For both setting towards washing powder temperature T 1; Also set the program of wash temperature T2; Main wash into that hot water injection's clothing powder time t is set at 2 minutes, the hot water temperature dashes washing powder temperature T 1 for what set, towards the heating of washing powder water inlet and temperature control as implement described in one.
After flooding time was greater than 2 minutes, then regulates heating module heating power, I road and II way solenoid valve aperture and satisfy the washing water temperature requirements according to the wash temperature T2 that sets.
Heating module quits work when the water inlet water level reaches " set water level-1 retaining ", only opens the water inlet of I way solenoid valve and absorbs the heat that heating module distributes and get final product, begins to wash up to the designated water level of intaking.Heating module power is reduced to 0 gradually when stopping to heat, rather than directly reduces to 0 by high-power.
When just beginning to heat, heat to the power of heating module energising earlier according to " rated power/2 ", behind the 3s heating module power is brought up to rated power gradually; Then be to be reduced to 0 gradually when stopping to heat, rather than directly close by at that time heating power.Doing like this is to have avoided unexpected high-power powering on or heavy current impact that high-power outage causes, has protected control circuit and heating module well.
And I road and II way solenoid valve are almost all opened, realize the method for constant temperature through regulating heating module power, have realized big flow constant temperature water inlet, have saved flooding time.
Referring to Fig. 3 to Fig. 4, the washing machine of the above-mentioned control method for washing of employing of the present invention is shown.Heater among the present invention is loaded on washing machine top, and between water intaking valve and water injection box, both sides are connected with water injection box with water intaking valve through water supply hose.Washing machine comprise casing 1, splendid attire washings urceolus 2, be sleeved on the inner core 3, water feed apparatus, drainage arrangement, the control system that are used for the splendid attire washing clothes in the outer bucket; Said water feed apparatus comprises electromagnetic valve 4, heating module 6, water injection box 8; Heating module 6 one ends connect electromagnetic valve 4 through water inlet pipe 5, and the other end connects water injection box 8 through outlet pipe 7.For multichannel water inlet, electromagnetic valve is adopted and is that triple valve, heating module 5 comprise heater 9, two water inlets 51,52 among the present invention; Delivery port 7, temperature sensor 10; The I road water inlet pipe of triple valve is attached on the heater and can water be heated, and II road water inlet pipe advances cold water, and I road and II way solenoid valve use the direct current generator of adjustable valve aperture respectively; This direct current generator can be set according to leaving water temperature and regulate the water valve aperture automatically, adjusts the discharge size.Said temperature sensor 10 be installed in the hot and cold water with after outlet pipeline 7 on, temperature sensor is loaded on the water pipe bottom, hour also can touch current to guarantee current, accurately records water temperature.
Heating module adopts and becomes power control in the washing machine of the present invention, and heating module power is more than or equal to 1500 watts.
In sum, through adopting above-mentioned technical scheme, adopt 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, through programme-control, in the water inlet process, running water is heated; Improve the usefulness of washing powder, thereby improve detersive efficiency.
Certainly; The present invention is not limited to above-mentioned giving an example; The technical scheme that it will be apparent to those skilled in the art that, under the situation that does not break away from the spirit or scope of the present invention, this technical scheme all is suitable at impeller-type, drum-type, agitator type washing machine and other similar scrubber; The present invention is made various modifications and changes in claim of the present invention and be equal in the scope of replacement, and then such modification and change are contained in the present invention.
