Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Device embodiment
Fig. 1 is the structural representation with washing machine into water heating function provided by the invention.As shown in Figure 1, this washing machine had into water heating function is roller washing machine, and comprise washing machine urceolus and the inner core being positioned at washing machine urceolus, described washing machine urceolus is provided with water inlet 11, and described water inlet 11 is connected with water inlet pipe 2.Described water inlet pipe 2 is provided with electromagnetic valve 3, and described water inlet pipe 2 is also provided with heater 4.
Because described heater 4 is through water inlet pipe, and the relative table top in its position is comparatively near, and current mesa material mostly is wooden, plastic or other material.Heater 4 is instantaneously by cool water heating simultaneously, and the power of heater 4 needs enough large, and the heat thus produced can be a lot.If described heater 4 itself and extraneous thermal insulation are not by force, then heater 4 likely causes certain influence to the security of water inlet pipe and table top.For overcoming the above problems, described heater 4 itself and extraneous thermal insulation are necessarily eager to excel.In the present embodiment, there is heat-proof device in the arranged outside of described heater 4.Described heat-proof device can intercept the heat that heater 4 produces and derive, and then causes certain influence to the security of water inlet pipe and table top, reduces heat and to go out caused energy loss, be conducive to the lifting of water temperature, save the energy.
In the present embodiment, preferably, described heater 4 is between electromagnetic valve 3 and water inlet 11.
Because the cold water of coming in from electromagnetic valve 3 can be heated to temperature required by described heater 4 in advance, and then go the washing agent rinsed in detergent box to make it enter inner tank of washing machine, so make the organized enzyme of washing agent or washing powder effect can be effectively played, enhance the dirt-removing power of washing agent.Meanwhile, heat-proof device can intercept the heat that heater produces and derive, and reduces heat and to go out caused energy loss, be conducive to the lifting of water temperature, save the energy.
In the present embodiment, washing machine is also provided with controller 5.Described electromagnetic valve 3 and heater 4 are all connected with described controller 5.Send signal by controller 5 to electromagnetic valve 3 or heater 4 and carry out Controlling solenoid valve 3 or heater 4 works.
In the present embodiment, washing machine is also provided with warning device 6, described warning device 6 is connected with controller 5, sends signal control warning device 6 report to the police by controller 5 to warning device 6.
In the present embodiment, in order to accurately control the heating-up temperature of water, be provided with temperature sensor in described heater 4, described temperature sensor is connected with described controller 5.When described heater 4 is opened and is heated the water flow through, described temperature sensor detects the actual temperature of water in real time and the water temperature value detected is sent to controller 5, controller 5 pairs of actual temperatures judge, when the absolute value of the difference between water temperature and default water temperature exceedes predetermined threshold value, Controlling solenoid valve 3 regulating water flow, controls warning device 6 simultaneously and reports to the police.
Embodiment of the method
Fig. 2 is control method for washing machine flow chart provided by the invention.As shown in Figure 2, this has the control method for washing machine into water heating function, and for controlling the above-described washing machine had into water heating function, it comprises the following steps:
S10, controller 5 Controlling solenoid valve 3 are intake with default flow of inlet water, and control heater 4 heats the water flowed through with default heating-up temperature T0 simultaneously.Wherein, the value presetting flow of inlet water and default heating-up temperature T0 is all pre-set and put into program.
In the present embodiment, preferably, the scope that described default heating-up temperature T0 is is 40 "=T0 "=50 degrees Celsius.This temperature can make the organized enzyme of washing agent or washing powder effect can be effectively played, enhance the dirt-removing power of washing agent.But described default heating-up temperature T0 is not limited thereto temperature value, according to actual needs, 40 degrees Celsius can also be greater than or less than.
Fig. 3 is a kind of preferred embodiment flow chart of the control method for washing machine that the specific embodiment of the invention provides.As shown in Figure 3, a kind of preferred embodiment of control method for washing machine comprises the following steps:
S00, controller 5 detect whether having heaters 4 start signal inputs, if receive heater 4 start signal, then perform step S10; Otherwise heater does not start, washing machine washs according to normal condition.
S10, controller 5 Controlling solenoid valve 3 are intake with default flow of inlet water, and control heater 4 heats the water flowed through with default heating-up temperature T0 simultaneously.Wherein, the value presetting flow of inlet water and default heating-up temperature T0 is all pre-set and put into program.
S20, temperature sensor real-time detection practical water temperature value T1, and by actual water temperature value T1 transmit control device 5.
S30, controller 5 judge the absolute value of actual water temperature value T1 and default heating-up temperature T0 difference | whether T1-T0| is more than or equal to predetermined threshold value Δ T, if be more than or equal to predetermined threshold value Δ T, then performs step S40; Otherwise, return and perform step S20.
In the present embodiment, preferably, if the absolute value of actual water temperature value T1 and default heating-up temperature T0 difference | T1-T0| is greater than predetermined threshold value Δ T, then controller 5 is judged as that abnormal conditions occur, controls warning device 6 simultaneously and reports to the police.
In the present embodiment, what described warning device 6 can be independent is buzzer, also can be independent be can the display unit of display, or be buzzer and display unit simultaneously.
The flow of inlet water of S40, controller 5 electromagnetic valve for adjusting 3, until the absolute value of actual water temperature value T1 and default heating-up temperature T0 difference is less than predetermined threshold value Δ T.
In the present embodiment, because season is different, the water original temperature flowing through heater 4 is different, and the power of adding different heaters is different, so the absolute value of actual water temperature value T1 and default heating-up temperature T0 difference can change.When its value is more than or equal to predetermined threshold value Δ T, then controller 5 is according to the flow of inlet water of the temperature rise electromagnetic valve for adjusting 3 of the power of heater 4 and water.
S50, controller judge that whether the setting water yield is all by electromagnetic valve 3, if the setting water yield is all by electromagnetic valve 3, then performs step S60; Otherwise, perform step S20.
S60, electromagnetic valve 3 stop water inlet, and controller 5 control heater 4 stops heating.
Adopt above method, strictly can control the temperature of the water entered in washing machine, the water temperature of rinsing washing agent or washing powder is made to remain on preset temperature or have small variations up and down at preset temperature, make the organized enzyme of washing agent or washing powder effect can be effectively played, greatly strengthen the dirt-removing power of washing agent.
The heater that this programme provides not only can be used on roller washing machine, also can be used on other laundry machine such as rotary drum washing machine, washing-drying integral machine.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
