Problems solved by technology

Although this method can achieve control, the effect of control is not good, and misjudgment will occur in many cases, such as the difference between different materials and the error of weight judgment. Due to the limitation of judgment accuracy and control accuracy, this method is impossible to achieve 'the water level does not pass through the clothes. That's it, to achieve the optimal washing state' the original design intention

Embodiment 1

[0046] Such as figure 1 As shown, this example provides an automatic water level control system for washing machines based on water inflow detection, including:

[0047] The control module is used to realize the automatic control of the water level of the washing machine;

[0048] The water level detection module uses a water level sensor to detect the state of the water level in real time, obtains the corresponding water level change, and sends the water level change to the control module;

[0049] The water inflow detection module uses a flow sensor to detect the water inflow at the water inlet in real time, and calculates the inflow by accumulating the water inflow and sends it to the control module;

[0050] Wherein, the control module includes a comparison unit, and the comparison unit is used for comparing the variation of the water level of the empty cylinder with the variation of the loading water level after loading the clothes, until the variation of the loading wat...

Embodiment 2

[0063] The difference from Embodiment 1 is that the control module described in this embodiment uses an MCU to realize automatic control of the water level of the washing machine.

[0064] This example further adopts the above-mentioned technical solution, which has the advantage of detecting the inflow of water added to the washing machine through the flow sensor, detecting the change of the water level in the washing machine in real time through the water level sensor, and using the MCU to calculate the relationship between the change in water level and the change in water inflow. Judging when the water level has just covered the clothes, in order to achieve precise control of the relationship between the water level and the clothes.

Embodiment 3

[0066] The difference from Embodiment 2 is that the water inflow detection module described in this example uses a single-chip microcomputer to accumulate the inflow flow to obtain the inflow and send it to the control module.

[0067] Wherein, the water inflow rate is real-time detected water inflow data, and by accumulating the real-time data within a fixed time period, the total water inflow volume within the time period can be obtained.

[0068] This example further adopts the above-mentioned technical solution, and its advantage is that the flow sensor is introduced, and through its cooperation with the single-chip microcomputer, the actual water injection volume in the washing machine can be detected, that is, the change of water inflow, and the water level sensor is used to check the real-time change of the water level , if the clothes are completely covered by water, the change in the loading water level is the same as the change in the water level of the empty bucket, ...

Abstract

The invention provides a washing machine water level automatic control system based on water inlet quantity detection and a washing machine water level automatic control method. The washing machine water level automatic control system based on water inlet quantity detection comprises a control module, a water level detection module and a water inlet quantity detection module. The control module is used for automatically controlling water level of the washing machine, a water level sensor is used for detecting water level conditions in real time to obtain corresponding water level variable quantity and sending the variable quantity to the control module, and a flow sensor is used for detecting water inlet flow at a water inlet pipe in real time, obtaining water inlet quantity by summing water inlet flow, and sending the water inlet quantity to the control module. The control module comprises a comparison unit which is used for comparing water level variable quantity of an empty cylinder with loading water level variable quantity of the cylinder loaded with clothes, and water adding is not stopped until the loading water level variable quantity is equal to the water level variable quantity of the empty cylinder. Water level can be precisely controlled by the control module, water adding is automatically stopped when clothes are covered by water, and washing effectiveness and high control precision can be achieved.

Description

technical field [0001] The invention relates to an automatic water level control system for a washing machine, in particular to an automatic water level control system for a washing machine based on water inflow detection and a method thereof. Background technique [0002] When using a washing machine to wash clothes, after soaking the clothes with water, the water level should not exceed the clothes; because the washing machine uses the friction between the clothes and the washing machine barrel, the clothes room, and the clothes and water to clean the clothes. If there is too much water, Clothes are not compact, resulting in reduced friction, and the washing effect is not good. On the contrary, if the water level does not cover the clothes, the clothes are not in full contact with the water, resulting in dry friction of the clothes, and the washing effect is even worse. Clothing may be damaged. [0003] At present, some washing machines require the controller to be able t...
