Problems solved by technology

At the same time, in order to be able to adjust the water quality of the water purifier, it is necessary to detect the current and voltage conditions of the electric desalination equipment and according to the water quality of the tap water, the existing electric desalination equipment uses several fixed modes for desalination, but with the environmental water quality interference and other factors, such as differences in raw water quality in different regions, the desalination effect of the same product in different regions is often unsatisfactory, and even if the raw water quality is good, users still need to wait for a certain period of time, resulting in poor user experience

Embodiment 1

[0049] Embodiment 1 of the present invention firstly provides a device for regulating water quality, specifically a water quality regulating device for water purifiers. Some force majeure factors are ignored, such as the difference in water quality in various regions, such as the different effects according to the fixed model, which will affect the quality of water used by users. The following will be described through specific examples.

[0050] see figure 1 , figure 1 It is a block diagram of the device for regulating water quality provided in the embodiment of the invention. Specifically, it is a device 100 for purifying water in a water purifier, and the device 100 includes:

[0051] Electric desalination equipment 10, used to purify raw water;

[0052] The first TDS (Total Dissolved Solids: total dissolved solids) sensor 20 is arranged at the water inlet of the electric desalination device 10, and is used to detect the first total dissolved solids value of the raw wat...

Embodiment 2

[0124] Embodiment 2 of the present invention provides a method for adjusting water quality, specifically a method for adjusting water quality for water purifiers. Regional water quality and different time points will have differences in water quality, resulting in users wanting to achieve the required water quality when using the water purifier. The water purification time is either fixed or inconsistent, such as in poor raw water quality. In some cases, users need to wait for a long time, which affects user experience and is not suitable for commercial environments. The technical scheme is set forth below through specific examples.

[0125] It should be noted that Embodiment 2 of the present invention can be an improvement on the control of the device provided in Embodiment 1. Therefore, those skilled in the art can understand Embodiment 2 with reference to the device provided in Embodiment 1.

[0126] see Figure 8 , Figure 8 It is a flowchart of a method for adjusting w...

Abstract

The embodiment of the invention provides a method and device for adjusting water quality and a water purifier. The method and device are applied to the water purifier. The water purifier comprises electric desalting equipment used for purifying raw water. The method comprises the following steps: acquiring a first total dissolved solid value of raw water input into the electric desalting equipment; under the condition that the first total dissolved solid value is greater than the target total dissolved solid value, determining a working voltage for controlling the electric desalting equipment to operate according to the first total dissolved solid value and the target total dissolved solid value; applying the working voltage to the electric desalting equipment so as to desalt the raw water and output purified water; acquiring a second total dissolved solid value of the purified water; and adjusting the working voltage through PID feedback control according to the difference between the second total dissolved solid value and the target total dissolved solid value.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a method, a device and a water purifier for adjusting water quality. Background technique [0002] It is a common technical means for water purifiers to use electric desalination equipment. Electric desalination equipment needs to control the water inflow to the concentration chamber to obtain a specific fresh water recovery ratio. During the electric desalination process, it is necessary to apply a working voltage to the electric desalination equipment. At the same time, in order to be able to adjust the water quality of the water purifier, it is necessary to detect the current and voltage conditions of the electric desalination equipment and according to the water quality of the tap water, the existing electric desalination equipment uses several fixed modes for desalination, but with the environmental water quality Intervention and other factors, such ...
