Fig. 1 is the washing machine profilograph that has boiling function according to of the present invention.Fig. 2 is the schematic block diagram that has the washing machine of boiling function according to of the present invention.
As shown in Figure 1, the washing machine that has boiling function in according to the present invention, comprise the outer bucket 2 that is contained on the fuselage 1, interior barrel 3 of bucket 2 the insides outside, the rotary agitator 5 in bucket 3 bottoms in being contained in, be installed in the outer cover 4 that back is used for opening or shutting fuselage 1, be placed on the hot and cold water water intaking valve that is used to provide hot water and cold water on the outer cover 4, and a control panel.(not shown).
Be arranged on the power supply delivery unit 6 below outer barrel 2, belt pulley 7, belt 8 and laundry motor 9, their common function is to be used for driven agitator 5.
In addition, the recirculation heater that is used for heating 12 in being installed in below the bucket 3 is formed on being used for from the draining valve 10 of washing machine drainage of outer bucket 2 bottoms, is arranged on the inner temperature sensor 13 that is used for testing the heated temperature of slurry of outer bucket.
An overflow pipe 11 that is used for connecting interior bucket 3 tops and draining valve 10 outlets, its function are the passages that goes outside the cold water on interior bucket 3 tops is discharged to as filling with.
With reference to figure 2, control module 22 is connected at its input terminal with control panel 20, be used for receiving the laundry information of setting the situation of laundry processes such as the user, have temperature sensor 13 and be used for importing by it and detect the temperature probe unit 21 of temperature information to the control module 22.In addition, control module 22 is connected at its outlet terminal with laundry motor driver element 23 and is used for driving laundry motor 9, heat driven unit 24 is used for driving heater 12, inlet valve driver element 25 is used for driving hot water and cold water water intaking valve 14a and 14b, and draining valve driver element 26 is used for driving draining valve 10.
As shown in Figure 3, the water yield water level that is used to provide washing and boiling operation is split up into low water level L1, mid water levels L2 and high water level L3. overflow that water level L4 is provided with is higher than high water level L3, reaches the cold water that overflows water level L4 relatively and is discharged away by overflow pipe 11 when the termination pattern stops washing and boiling operation.
When being provided with washing and boiling program, even the user does not carry out any extra water level setting, control module 22 also can be opened hot water water intaking valve 14a under mode standard, provide hot water to reach mid water levels up to water level.
After water supply was finished, control module 22 driving heaters 12 heating supply water drove laundry motor 9 alternate rotation agitators 5 simultaneously and carry out washing and the operation of seething with excitement to advance with direction of retreat.
When carrying out washing and boiling operation, to import stop signal suddenly and stop washing and boiling operation or input draining signal and carry out drainage procedure, control module 22 is set termination patterns and is stopped washing and boiling process.
Whether when having set termination pattern, control module 22 detects the temperature of slurry, thereby decide slurry can discharge.If but the temperature of slurry is can not cause the discharge temperature that the user is scalded, control module 22 control draining drive valve unit 26 are opened draining valve 10, make that employed water is emitted immediately in washing and boiling operation.
Simultaneously, if but the temperature of the slurry that is monitored by temperature probe unit 21 is higher than discharge water temperature T r, such as 50 degrees centigrade, after termination pattern is set, but control module 22 is carried out the operation of reduction washing water temperature to discharge water temperature T r by providing cold water to enter outer bucket 2.
If but the difference between washing water temperature and the discharge water temperature is greater than reference value, such as 25 degrees centigrade, when washing water temperature was 75 degrees centigrade, control module 22 stopped laundry motor 9, provide cold water to drop to predetermined temperature simultaneously, such as 60 degrees centigrade up to washing water temperature.Therefore, when when providing cold water to be full of to overflow water level L4, cold water is discharged to the outside by overflow pipe 11, but the interval A that wherein is discharged from the temperature of water such as Fig. 4 shows and is significantly less than discharge water temperature T r..Stopping of laundry motor 9 is because underlying cause: but the temperature of slurry needed significant period of time during apparently higher than the temperature that is discharged from water before being dropped to discharge temperature, and the operation of laundry motor 9 may cause that hot water is discharged from by overflow pipe 11.
But the difference between washing water temperature and discharge water temperature is not more than reference value, setting termination pattern or because providing of cold water when having reduced the temperature of the water of doing washing, laundry motor 9 is driven alternate rotation agitator 5 and makes slurry and cold water rapid mixing with the direction that moves forward and backward.This has just reduced the temperature of slurry, but makes it near the discharge water temperature shown in Fig. 4 interval B.The mixing of cold water and slurry is discharged from by overflow pipe 11, and this makes the temperature transition that is discharged from water become to be higher than a little the temperature that can discharge water temperature.
When making that by providing of control laundry motor 9 and cold water but the temperature of slurry is lower than the discharge water temperature, control module 22 control draining valve driver elements 26 are opened draining valve 10, therefore slurry are discharged to the outside.In this case, but the temperature that is discharged from water is lower than the discharge water temperature, shown in the interval C of Fig. 4.
The process of control washing water temperature that has the washing machine of boiling function can be with reference to the process description of figure 5.In order to be easy to description, set under the prerequisite of termination pattern by the selection dehydration procedure in washing and boiling operation the hypothesis user, describe.Similarly, the situation that is applicable to that also termination pattern is executed by the user or be provided with automatically by the end of washing and boiling operation is described.
At first, whether control module 22 decision users set the process of washing and boiling at step S10 by using control panel 20.If washing and boiling process are set, open hot water water intaking valve 14a at step S30 control module 22 control inlet valve driver elements 25, thereby provide hot water to reach mid water levels L2 up to hot water.Otherwise control panel 22 stands by.
Drive laundry motors at step S30 control module 22 control laundry motor driver elements 23, thus agitate water and clothing, and in step S40 control heat driven unit 24 driving heater 12, thereby the slurry of heating supply.
Carrying out washing and boiling operation, when laundry motor 9 and heater 12 also are operated simultaneously, whether selecting dehydration by control panel 20 in 22 decisions of step S50 control module.If input dehydration signal, control module is set termination pattern, carries out drain operation according to the following step then.Otherwise control module 22 turns back to step S30, wherein washs and seethe with excitement to operate to be performed.
In termination pattern, detect the temperature of slurry at step S60 control module 22 by temperature probe unit 21, but whether be higher than discharge water temperature T r, such as 50 degrees centigrade in the temperature that step S70 monitors slurry.But if testedly be not higher than discharge water temperature T r with coolant-temperature gage, the danger in that step S71 control module 22 decision users are not scalded drives draining valve driver element 26 then and opens draining valve 10, to discharge washing and boiling operation water.After this, at step S72, control module 22 drives laundry motor 9 and carries out dehydrating operations, returns then.
Can discharge water temperature Tr if the water temperature that detects at step S70 is higher than, control module control water discharging valve driver element 25 is opened cold water water intaking valve 14b, thereby at step S80 supply cold water.Determine washing water temperatures whether to be higher than at step S90 control module 22 temperature T a is set, such as Tr and referential data sum.If but the difference between washing water temperature and the discharge water temperature is not higher than reference value, such as 25 degrees centigrade, when tested water temperature was not higher than set water temperature, control module 22 drove laundry motors 9 at step S91 control laundry motor driver element 23 and makes cold water and slurry rapid mixing.But this program repeats to turn back to step S60 is lower than the discharge water temperature up to washing water temperature.
If tested washing water temperature and the difference that can discharge between the water temperature are higher than reference value, when at step S90 as the result who stops, washing water temperature is higher than when being set temperature T a, stops laundry motor 9 at step S100 control module 22 control laundry motor driver elements 23.Detect the temperature of slurry by temperature probe unit 21 at step S110 control module 22.This process repeats to turn back to step S90 and cold water is flowed into up to washing water temperature and the difference that can discharge between the water temperature be equal to or less than reference value.If the temperature of slurry is lowered the difference that is used for reducing washing water temperature and can discharges water temperature, control module 22 drives laundry motor 9 cold water and slurry is as above described mixing mutually.Reach in the time of can discharging water temperature if the temperature of slurry is further reduced, draining valve 10 is opened, to discharge used water in washing and boiling operation.
Although do not describe in detail in the embodiment formerly, even without in washing and boiling operation, termination pattern being set, termination pattern the washing and boiling finish after by automatic setting, therefore depend on the water temperature of manipulating in washing and boiling, slurry can be lowered to by previous operating in and be discharged away can discharge water temperature the time.
According to foregoing the present invention, when the termination pattern of be used for terminating washing and boiling operation by automatically or when forcing to set, washing water temperature is lowered by the cold water that flows into, but the operation of laundry motor makes cold water mix with slurry up to further reduction water temperature up to discharge temperature, then, slurry emitting by safety.Therefore, prevented that the user from being scalded, corresponding, improved the reliability of products energy.
Although the preferred embodiment among the present invention is disclosed with way of illustration, under the condition of the spirit and scope of the invention of announcing in not deviating from following claim, various modifications replenish and replacement all will receive an acclaim.
