A washing machine and a control method for the washing machine

Abstract

The invention relates to a washing machine, which comprises a water inlet channel connecting the external water supply pipeline of the washing machine and a washing bucket, an optimization device for optimizing the water quality of the water inlet flow is provided on the water inlet channel, and a The flow rate control device for controlling the flow rate of the influent water and the second water quality detection device for detecting the water quality of the influent water flow, the second water quality detection device is connected with the flow rate control device, so that the flow rate control device can detect the water quality according to the second water quality detection device The information controls the flow rate of the incoming water flow. The present invention also relates to a control method for a washing machine, which includes an executable first water intake plan, the first water intake plan is to optimize the water quality of the incoming water flow and then pass it into the washing tub, the washing machine enters water, and executes the first water intake When planning, control the flow rate of the influent water before water quality optimization treatment according to the quality of the influent water. The invention ensures the water quality of the water flowing out of the optimizing device by controlling the flow velocity of the water flowing into the optimizing device.

Description

technical field [0001] The invention relates to a washing machine, and also relates to a control method of the washing machine. Background technique [0002] Hard water will reduce the efficiency of the detergent. When the laundry water contains cations such as divalent calcium ions and magnesium ions as water hardening components, these calcium ions and magnesium ions will react with the surfactant in the detergent to form insoluble metals. Soap, reduces the amount of surfactants that are good for laundry and reduces stain release. Clothes washed in hard water look dark and sloppy, and feel rough and stiff to the touch. Divalent calcium ions, magnesium ions, and dirt combine to form insoluble salts that make stains more difficult to remove. And the dirt on the clothes introduces more invisible minerals into the wash water, making the water harder. Washing clothes in hard water can also damage the fibers of the garment, reducing the life of the garment by up to 40%. [0...

[0004] However, the above method simply allows tap water to pass through the resin and then flows into the washing tub, but does not effectively monitor the softening process and the state of the resin. Among them, the softening effect is related to the flow rate of tap water flowing through the softening module. If a fixed flow rate is used, It will make the tap water with high hardness unable to fully soften, and the tap water with low hardness will prolong the water intake time
