Fig. 2 is the structural representation of washing machine automatic release device.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
The control mode of a kind of washing of drum type washing machine liquid injected volume as shown in Figure 1, this control mode comprises the following steps:
(1) start washing machine, obtain the required cleaning solution total amount A thrown in.The cleaning solution total amount A of the required input described in step (1) is that washing machine is judged according to washing weight or other automatic decision mode complete machines, or artificial setting.
(2) start washing machine automatic release device, obtain the initial output power P of its power set." starting washing machine automatic release device; obtain the initial output power P of its power set " described in the present invention, refer to after the startup of washing machine automatic release device also steady operation, try to achieve its power output mean value within a period of time of steady operation, as the initial output power P of power set.
(3) according to initial output power P, the range of viscosities M of cleaning solution and the input speed V of cleaning solution is tried to achieve.
(4) according to the cleaning solution total amount A of required input and the input speed V of cleaning solution, the release time T of cleaning solution is tried to achieve.
As shown in Figure 2, washing machine automatic release device is made up of driving power and power set two large divisions usually, and power set are positioned at detergent box, for drawing or promoting cleaning solution in water inflowing box, realizes automatically throwing in; Driving power, for providing energy for power set.Same cleaning solution, under different environment temperatures, its viscosity is different; And power set are when drawing or promote the cleaning solution of different viscosities, power set can be subject to the resistance of different size; Therefore, when drawing or promote the cleaning solution of different viscosities, the power output of power set has bigger difference.Concrete rule is: if cleaning solution viscosity is large, then power set power output is large, and cleaning solution input speed is little, and the required cleaning solution release time is long.Otherwise if cleaning solution viscosity is little, then power set power output is little, cleaning solution throws in speed greatly, and the required cleaning solution release time is short.
Table 1
The cleaning solution viscosity at different ambient temperatures of what table 1 provided is different brands.As can be seen from Table 1, along with the rising of environment temperature, the viscosity of cleaning solution reduces gradually.And after cleaning solution viscosity reduces, the intermolecular power of pullling of cleaning solution reduces, so also less to overcoming the power consumption pullling power between liquid to power set.Therefore, the cleaning solution of different viscosities can produce different resistances to power set, and when cleaning solution viscosity is large, the resistance produced power set is just large, needs to consume larger electric energy; When cleaning solution viscosity hour, the resistance produced power set is just little, needs to consume less electric energy.
Table 2
Table 3
What table 2 provided is power set when being gear pump, at varying environment temperature, and the cleaning solution of different brands, the injected volume in every 30 seconds.As can be seen from Table 2, be no matter the cleaning solution of any brand, along with the rising of environment temperature, its injected volume in every 30 seconds increases gradually.What table 3 provided is power set when being piston pump, at varying environment temperature, and the cleaning solution of different brands, the injected volume in every 30 seconds.As can be seen from Table 3, be no matter the cleaning solution of any brand, along with the rising of environment temperature, its injected volume in every 30 seconds increases gradually.Therefore, from the experimental data of table 2 and table 3, the cleaning solution injected volume in every 30 seconds, along with the rising of temperature increases.That is, environment temperature raises, and cleaning solution viscosity reduces, and speed increase thrown in by cleaning solution.
In sum, the experimental data of associative list 1, table 2 and table 3 is known, speed thrown in by environment temperature, cleaning solution viscosity, cleaning solution, pass between power set power output is: along with the rising of environment temperature, cleaning solution viscosity diminishes, the power output of power set diminishes, and cleaning solution is thrown in speed and become large; Along with the reduction of environment temperature, cleaning solution viscosity becomes large, and the power output of power set becomes large, and cleaning solution is thrown in speed and diminished.According to the difference of different viscosities cleaning solution to power set resistance, by detecting power set input current or power output, then throw in relation corresponding between speed according to cleaning solution viscosity, power set power output, cleaning solution, try to achieve the input speed of cleaning solution.
Certain cleaning solution that the present invention is chosen at varying environment temperature by setting carries out many experiments, obtains statistics as shown in table 4 and table 5:
Table 4
Table 5
The power set that table 4 is automatic release device are gear pump, and when required cleaning solution injected volume is 50ml, power set power output, cleaning solution viscosity, cleaning solution throw in speed and the corresponding relation between the cleaning solution release time.The power set that table 5 is automatic release device are piston pump, and when required cleaning solution injected volume is 50ml, power set power output, cleaning solution viscosity, cleaning solution throw in speed and the corresponding relation between the cleaning solution release time.Due to the pump rated power difference to some extent of different manufacturers, therefore, the experimental data in table 4 and table 5 is the corresponding relation obtained according to the pump rated power of adopted gear pump and piston pump sample.The difference of power set, can cause each data area variant.Experimental data given by table 4 and table 5, when setting cleaning solution needed for injected volume be 50ml, when power set are gear pump, if the initial output power of the power set obtained is 2 ~ 3W, then the viscosity of the cleaning solution of its correspondence is 69, and it is exactly that required time thrown in by this cleaning solution that this cleaning solution corresponding to cleaning solution viscosity throws in speed for 90ml/min throws in speed with injected volume needed for cleaning solution divided by cleaning solution again.Other by that analogy.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
