Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a concentrated water zero-discharge reverse osmosis water purifier. Background Art

[0002] Currently, water purifiers convert natural water into pure water. During this process, the concentrated water produced is typically discharged directly into the sewer, resulting in a significant waste of water resources. The inventors have designed a zero-discharge concentrated water reverse osmosis water purifier that can store this concentrated water in a pressure tank for domestic use, significantly improving water utilization. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a concentrated water zero-discharge reverse osmosis water purifier in view of the deficiencies in the existing technology.

[0004] In order to solve the above technical problems, the present utility model adopts the following technical solutions.

[0005] A concentrated water zero-discharge reverse osmosis water purifier comprises a main pipeline, a domestic water pipe, a first connecting pipe, a second connecting pipe and a third connecting pipe, wherein one water outlet of the main pipeline is connected in sequence to a pre-filter device, a first solenoid valve, a pressure-stabilizing valve, an activated carbon filter, an RO reverse osmosis filter, a first check valve, a first high-pressure switch and a pure water faucet; another water outlet of the main pipeline is connected to a domestic water pipe, and the RO reverse osmosis filter is connected in sequence to a concentrated water solenoid valve, a second high-pressure switch, a second check valve and the domestic water pipe; a concentrated water temporary storage tank is connected between the second high-pressure switch and the second check valve via the first connecting pipe, a second connecting pipe is connected between the concentrated water solenoid valve and the second high-pressure switch, and the second connecting pipe is connected in sequence to the second solenoid valve and the third connecting pipe.

[0006] A preferred solution is that one water outlet of the domestic water pipe is connected to a natural water faucet, and the other water outlet is connected to a dishwasher, a washing machine or a toilet.

[0007] The concentrated water zero-discharge reverse osmosis water purifier provided by the embodiment of the present invention has at least the following beneficial effects: natural water in the main pipeline passes through the pre-filter device, the first solenoid valve, the pressure-stabilizing valve, the activated carbon filter, the RO reverse osmosis filter, the first check valve and the first high-pressure switch in sequence, and then flows out of the pure water faucet after being filtered. At the same time, the concentrated water produced by the RO reverse osmosis filter passes through the concentrated water solenoid valve and the second high-pressure switch and enters the concentrated water temporary storage tank for storage. When the concentrated water stored in the concentrated water temporary storage tank reaches a certain amount, the concentrated water in the concentrated water temporary storage tank can flow to the domestic water pipe for domestic use; when the concentrated water in the concentrated water temporary storage tank is full, the second solenoid valve opens, and the concentrated water produced by the RO reverse osmosis filter passes through the second connecting pipe, the second solenoid valve and the third connecting pipe to flow out.

[0008] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In addition, in order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0013] like Figure 1As shown, an embodiment of the present application provides a concentrated water zero-discharge reverse osmosis water purifier, including a main pipeline 1, a domestic water pipe 2, a first connecting pipe 3, a second connecting pipe 4 and a third connecting pipe 5. One water outlet of the main pipeline 1 is connected to a pre-filter device 6, a first solenoid valve 7, a pressure-stabilizing valve 8, an activated carbon filter 9, an RO reverse osmosis filter 10, a first check valve 11, a first high-pressure switch 12 and a pure water faucet 13 in sequence; another water outlet of the main pipeline 1 is connected to a domestic water pipe 2, and the RO reverse osmosis filter 10 is connected to a concentrated water solenoid valve 14, a second high-pressure switch 15, a second check valve 16 and a domestic water pipe 2 in sequence; a concentrated water temporary storage tank 17 is connected between the second high-pressure switch 15 and the second check valve 16 through the first connecting pipe 3, a second connecting pipe 4 is connected between the concentrated water solenoid valve 14 and the second high-pressure switch 15, and the second connecting pipe 4 is connected to a second solenoid valve 18 and a third connecting pipe 5 in sequence.

[0014] like Figure 1 As shown, Figure 1 The middle arrows indicate the direction of water flow. Natural water in main pipeline 1 passes through pre-filter 6, first solenoid valve 7, pressure-stabilizing valve 8, activated carbon filter 9, RO reverse osmosis filter 10, first check valve 11, and first high-pressure switch 12 in sequence. After being filtered, the natural water flows out of pure water tap 13. Simultaneously, the concentrated water produced by RO reverse osmosis filter 10 passes through concentrated water solenoid valve 14 and second high-pressure switch 15, and enters concentrated water temporary storage tank 17 for storage. When the concentrated water stored in concentrated water temporary storage tank 17 reaches a certain amount, the concentrated water in concentrated water temporary storage tank 17 can flow to domestic water pipe 2 for domestic use, thus preventing waste of concentrated water filtered by RO reverse osmosis filter 10. When concentrated water in concentrated water temporary storage tank 17 is full, second solenoid valve 18 opens, and concentrated water produced by RO reverse osmosis filter 10 flows out through second connecting pipe 4, second solenoid valve 18, and third connecting pipe 5.

[0015] like Figure 1 As shown, one outlet of the domestic water pipe 2 is connected to a natural water faucet 19, and the other outlet is connected to a dishwasher 20, a washing machine or a toilet.

[0016] like Figure 1 As shown, when the concentrated water stored in the concentrated water temporary storage tank 17 reaches a certain amount, the concentrated water in the concentrated water temporary storage tank 17 can flow to the domestic water pipe 2, and the water flowing out of the domestic water pipe 2 can flow to the natural faucet 19, or flow to the dishwasher 20, washing machine or toilet for domestic water use.

[0017] The above is a specific implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
