A control method and control system for a pure water machine

Abstract

The invention discloses a control method of a water purifying machine. The control method of the water purifying machine comprises a control method for automatically preparing pure water by the water purifying machine, and a control method for continuously preparing and supplying the pure water, and meanwhile, also comprises an automatic recycling control method and an automatic discharging control method of concentrated water generated in a process of preparing the pure water by the control method of the water purifying machine. The invention also discloses a control system for the control method of the water purifying machine; the control system comprises a water preparing device used for preparing the pure water and a controller used for controlling preparation of the pure water and the concentrated water; the invention also discloses the water purifying machine based on the control system. The control method of the water purifying machine, which is provided by the invention, can realize effects of saving water and saving energy, achieves purposes of improving and prolonging the service efficiency and the service life of a reverse osmosis membrane, has beneficial effects that purified water is produced during use of ordinary water, and is stored in a water storage pressure tank for pressure accumulation, so as to be used in case of need; a filter membrane can be flushed, so that the service efficiency and the service life of the water purifying machine are improved and prolonged; when the stored purified water is used, no extra concentrated water is generated, and no waste water is discharged; the protection is started in case of water deficiency, so as to prevent the water purifying machine from being damaged.

Description

technical field

[0001] The invention belongs to the technical field of water treatment, and in particular relates to a control method and a control system of a pure water machine. Background technique

[0002] In daily life, household water is mainly used for ordinary water (including laundry, washing vegetables, bathing, floor care, etc.), the per capita water consumption quota for ordinary houses is 130-300L / day, and pure water is only used for drinking water and cooking Etc., common people's consumption of drinking water is about 2L / day, wherein about 1L of direct drinking water, it can be seen that ordinary water accounts for more than 99% of the total water consumption. At present, the domestic pure water machine is used for the production of drinking pure water. While producing pure water, concentrated water is produced, and the production of concentrated water is more than 60%. There are mainly the following methods for the treatment of this part of concentrated water...
