Embodiment 1

[0041] Such as figure 1 As shown, this embodiment introduces a washing machine, which includes an inlet waterway 1 connecting the external water supply pipeline of the washing machine and the washing tub. A flow rate control device 3 for controlling the flow rate of the influent water flow and a second water quality detection device 4 for detecting the water quality of the influent water flow located upstream of the optimization device 2 are arranged on the top, the second water quality detection device 4 is connected to the flow rate control device 3 connected so that the flow velocity control device 3 controls the flow velocity of the water inlet channel 1 according to the detection information of the second water quality detection device 4 .

[0042] In the present invention, the flow rate control device 3 is arranged upstream of the optimization device 2 to realize the control of the flow rate of the water flowing into the optimization device 2. The residence time of the ...

Embodiment 2

[0056] Such as figure 1 As shown, the difference between this embodiment and Embodiment 1 is that the second water quality detection device 4 is arranged downstream of the optimization device 2 to detect the water quality of the influent water flow downstream of the optimization device 2, so that the flow rate control device 3 according to the downstream of the optimization device 2 Influent water quality control optimization device 2 upstream flow rate of influent water. In a corresponding washing machine control method, the detected inflow is the inflow after water quality optimization treatment.

[0057] In the present invention, the second water quality detection device 4 is arranged downstream of the optimization device 2 to detect the water quality of the water flowing out of the optimization device 2, so that the control of the flow rate is based on the water quality of the water flow out of the optimization device 2, so that the outflow The water quality of the optimi...

Embodiment 3

[0061] Such as figure 1 As shown, the difference between this embodiment and Embodiments 1 and 2 is that the optimization device 2 includes an optimization cavity, and an optimization material with water quality optimization capability is arranged inside the optimization cavity, and the water inlet channel 1 passes through the optimization cavity and communicates with the optimization cavity . Optimizing substances are used to improve water quality parameters.

[0062] The water quality optimization capability of the optimization substance at least includes reducing the hardness of the influent water flow. The optimized substance can be ion exchange resin, or other substances that can reduce the hardness of influent water flow. In a corresponding washing machine control method, the water quality optimization treatment at least includes reducing the hardness of the incoming water flow.

[0063] The washing machine also includes a regeneration device 5. The regeneration devic...

Abstract

The invention relates to a control method of a washing machine. The control method includes an executable first water inlet scheme, the first water inlet scheme includes that inflow water is subjectedto water quality optimization treatment prior to being fed into a washing drum, and when water is fed into the washing machine and the first water inlet scheme is executed, the inflow rate before water quality optimization treatment is controlled according to inflow water quality before and/or after water quality optimization treatment. The invention further relates to the washing machine, whichcomprises a water inlet passage communicated with an external water supply pipeline and the washing drum of the washing machine. An optimization device for water quality optimization is arranged on the water inlet passage which is provided with a flow rate control device, the flow rate control device is positioned at an upstream position of the optimization device and used for controlling the flowrate, and a first water quality detection device which is positioned at an upstream position of the optimization device and used for water quality detection and/or a second water quality detection device which is positioned at a downstream position of the optimization device and used for water quality detection are arranged on the water inlet passage. The first water quality detection device andthe second water quality detection device are connected with the flow rate control 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...
