Description

Water purifier

Technical Field

The invention relates to the field of household water purification, in particular to a water purifier.

Background

Along with the increasing concern about drinking water safety of people, the application of water purification unit is also more and more extensive. Water purification unit can effectively ensure drinking water safety to a certain extent through carry out depth filtration, purification treatment to water. The reverse osmosis water purifier is a mainstream water purifying device in the market at present, can filter silt, bacteria, mineral substances, heavy metals and the like in water to prepare pure water, and ensures the safety of drinking water, so that the reverse osmosis water purifier becomes a popular electric appliance product in family life.

TDS, also known as total dissolved solids, a higher value of TDS indicates more dissolved matter is present in the water. Total dissolved solids refers to the total amount of total solutes in the water, including both inorganic and organic content. Generally, the salt content of the solution is known approximately by the conductivity value, and generally, the higher the conductivity, the higher the salt content, and the higher the TDS. Among inorganic substances, there may be inorganic substances in molecular form in addition to components dissolved in ionic form. Since organic matter and inorganic matter in molecular form contained in natural water are not generally considered, the salt content is generally referred to as total dissolved solids.

Can have raw water, waste water and pure water simultaneously in the reverse osmosis filter core, and the TDS's of raw water and waste water concentration will be far above the TDS of pure water, however, reverse osmosis filter core is shutting down and is placing a period of time after, will lead to the ion in raw water and the waste water to diffuse to pure water one side through the RO membrane, when causing the start-up use once more, the TDS value of first cup water exists the problem that is too high and can't drink, influences user experience.

In addition, also have among the prior art and directly set up the water storage tank in the outside of purifier and avoid the direct outflow of the pure water that the reverse osmosis membrane is internal to store up to supply the user to use, but the water storage tank of big volume is under the state of long-time deposit water, breeds the bacterium easily.

As shown in fig. 1-11, a water purifier includes: a primary filter unit 1, the primary filter unit 1 having a raw water inlet and a purified water outlet; the reverse osmosis filter unit 2 is provided with a water inlet, a pure water outlet and a waste water outlet, and a booster pump 3 is arranged on a water flow path between the water inlet 23 and the pure water outlet 12; the water purifying device comprises a water circuit board 4, wherein the water circuit board comprises a pure water inlet 411, a pure water inlet 412, a pure water discharge outlet 413 and a pure water storage tank 5, the pure water storage tank 5 is communicated with the pure water inlet 412 and the pure water discharge outlet 413, the pure water inlet 411 is communicated with a booster pump 3 and the water inlet, the water purifying device has a water preparing state and a flushing state, in the water preparing state, the booster pump is started, water filtered by a reverse osmosis filtering unit enters the pure water storage tank through the pure water inlet, and finally flows out of the pure water discharge outlet; in the flushing state, the booster pump is turned off, and a flushing flow path is formed between the raw water inlet and the waste water outlet.

The water circuit board is provided with a pure water storage tank, and under the water making state, pure water filtered by the reverse osmosis filtering unit firstly enters the pure water storage tank and then flows to a pure water discharge port from the pure water storage tank for users to use. Like this, when the long-time back of shutting down of purifier, when the user used for the first time, the pure water of the high TDS in the reverse osmosis filter unit enters into pure water storage tank and the pure water in the jar and mixes the back and flow for the water of high TDS obtains diluting in the pure water storage tank. Under the flushing state, the booster pump is closed, and under the action of the water pressure of the raw water, the purified water filtered by the primary filtering unit can be directly utilized to flush the reverse osmosis filter element membrane. Through set up pure water storage tank and wash the flow path on the water route board, guarantee that the purifier can effectively solve the problem that the first cup of water TDS after the long-time standby is higher under system water state and the state of washing, realize not having the stale water state. Simultaneously, directly set up the pure water storage tank on the water route board, compare with the direct peripheral hardware bulky water storage tank in the past, prevent because the big volumetric water storage tank internal water yield of peripheral hardware is too much, deposit the secondary bacterial growing that water time overlength and lead to, set up little volumetric pure water storage tank on the water route board, can guarantee that the jar internal water is in the running water state as long as possible, even if lead to keeping in some water owing to long-time shut down, also can not breed the bacterium easily. When having solved the problem that the first cup TDS that brings of shutting down for a long time is high, also reduced the whole installation space of whole purifier, prevented that the peripheral hardware water storage tank from breeding the problem of bacterium. As shown in fig. 1 and 2, in the water-making state of the water purifier, after raw water is primarily filtered into purified water through the primary filter unit 1, the booster pump 3 sends the purified water into the reverse osmosis filter unit 2 to realize secondary filtration, so as to form purified water, the purified water filtered by the reverse osmosis filter unit 2 enters the purified water storage tank 5 to be stored, the wastewater precipitated by the reverse osmosis filter unit 2 is discharged through the wastewater outlet 42 in the state that the wastewater valve 9 is opened, and when a user takes water, the water in the purified water storage tank 5 flows out through the purified water outlet 421 under the action of pressure. When the water purifier is in a flushing state, a flushing flow path is formed, the water inlet valve 8 and the waste water valve 9 are opened and filled, purified water filtered by the primary filtering unit 1 flows to the reverse osmosis filtering unit 2 and flushes the surface of a reverse osmosis membrane of the reverse osmosis filtering unit, and then waste water flows out through the waste water outlet 422 to realize the cleaning of the reverse osmosis filtering unit 2.

It should be noted that the structure of the primary filter unit 1 is not limited in particular, and for example, it may be a filter element formed by one or more of PP (polypropylene) cotton and activated carbon.
