Problems solved by technology

[0003] There are two common water intake methods in the rinsing stage. The first water intake method is to directly inject a large amount of water for rinsing, regardless of the number and water absorption of the clothes. This method will obviously waste a lot of clothes when the number of clothes is small. of water
The second water intake method is to set a higher rinsing water level first. After absorbing water, the clothes in the tube will be replenished several times to complete the water intake in the rinsing stage. This water intake method adopts the method of washing while washing. , the advantage is that the water intake is determined according to the quantity and water absorption of the clothes, which can save a lot of water, but the water intake speed is slow in this way
Also, see Figure 4 As shown, in the second method, the amount of water inflow and the time of water inflow are roughly inclined, so a considerable part of the water does not flow in until the end of the rinsing process, and sometimes it is even in the stage of draining and drying , so a considerable part of the incoming water does not participate in rinsing, which not only affects the rinsing effect, but also causes waste of water that does not participate in rinsing

Embodiment 1

[0036] The unit of each symbol in this embodiment adopts the international standard unit.

[0037] Such as figure 1 As shown, a method for controlling water inflow in the rinsing stage of a drum washing machine provided in this embodiment includes the following steps:

[0038] Step S00: preset the water inlet coefficient K in the storage unit of the controller of the washing machine p .

[0039] Inlet coefficient K p The calculation formula is as follows:

[0040]

[0041] Among them, L p is the total amount of water inflow during the rinsing stage, L z is the total amount of water inflow during the washing phase.

[0042] That is to say, the ratio of the total amount of water inflow in the rinsing stage to the total amount of water inflow in the washing stage is defined as the water inflow coefficient K p , water ingress coefficient K p It can be considered as a coefficient that does not depend on the amount of clothes and the change of water absorption of clothes...

Embodiment 2

[0059] Such as figure 2 As shown, the difference between Embodiment 2 and Embodiment 1 is: in order to prevent the water inlet flow F of the solenoid valve a If an abnormality causes the calculation result in step S20 to be inaccurate, after step S10 and before step S20, the main washing water intake time T z Make reasonable judgments.

[0060] The method of rationality judgment is as follows:

[0061] S121: Preset the upper water intake upper limit T of the water intake duration of the washing stage in the storage unit of the controller of the washing machine zmax and the lower limit of water ingress T zmin ;

[0062] S122: The calculation unit of the controller will main wash water for a time T z and water intake upper limit T zmax and the lower limit of water ingress T zmin For comparison, the comparison method is as follows:

[0063] If T zmin z zmax , main wash water intake time T z The value of remains unchanged;

[0064] If T z ≤T zmin , take the time T of...

Embodiment 3

[0070] This embodiment also provides a water inflow control device used in the method for controlling water inflow in the rinsing stage of the drum washing machine in Embodiment 1 or Embodiment 2, including a controller, a water inlet pipe, and a solenoid valve arranged on the water inlet pipe, The solenoid valve is electrically connected with the controller and controlled by the controller. The controller is preferably a single-chip microcomputer system.

[0071] The interior of the controller is provided with a storage unit, a computing unit and an output unit. Among them, the storage unit is used to store the water inflow coefficient K p , upper limit of water intake T zmax And the lower limit of water ingress T zmin The default value related data. The computing unit is used to calculate the water intake time of the main wash T z Make reasonable judgments and calculate the time T of rinsing and water intake p , that is, the calculation process in the above steps is re...

Abstract

The invention discloses a water inlet control method for the rising stage of a front-loading washing machine and belongs to the field of washing control. The method includes: water inlet coefficient Kp is preset, the front-loading washing machine enters a washing stage, the main washing water inlet duration Tz of the washing stage is recorded, the rising water inlet duration Tp is calculated according to Kp and Tz, and the opening time of an electromagnetic valve is controlled according to Tp so as to complete the water inlet of the rising stage at one step. By the water inlet control method, water consumption at the rising stage is reduced, good rising effect is achieved, and the water inlet time of the rising state is shortened.

Description

technical field [0001] The invention relates to the field of washing control, in particular to a method for controlling water inflow in the rinsing stage of a washing machine. Background technique [0002] Ordinary washing procedures are usually composed of the washing stage of the clothes - the draining and drying stage - the rinsing stage - the draining and spinning stage, etc. In order to separate the detergent and stains from the clothes as much as possible in the clothes, the rinsing stage is usually repeated several times, and The rinsing stage uses a large amount of water so that the detergent and stains can be fully dissolved in water and then discharged. The rinsing stage of most drum washing machines is generally carried out twice, and the total water used for the two rinsings accounts for about two-thirds of the total water consumption of the washing machine to complete a laundry wash. Therefore, if the water in the rinsing stage can be used reasonably, it will be...
