Description

Waterway system and water purifier

Technical Field

The invention relates to the technical field of household appliances, in particular to a waterway system and a water purifier.

Background

In the related art, the water purifier uses tap water as water inlet, and can obtain direct drinking water or domestic water through filtering by different filter elements. The drinking water of the water purifier reaches the purified water level and can be directly drunk. The domestic water of the water purifier is also subjected to primary filtration, so that large-particle impurities and residual chlorine in the water are removed, and the water can be used for most domestic purposes, such as fruit washing, vegetable washing, oil washing and the like.

Domestic water of water purifiers in the market is generally filtered through a PP cotton filter element or an active carbon filter element, or is filtered through both the PP cotton filter element and the active carbon filter element, or is filtered through a composite filter element with the same function. Therefore, the domestic water of the water purifier has no other functions except the common filtering, and the washing effect is very limited.

When the water purifier with the microbubble technology is used for living water, a large amount of microbubbles can be added into the living water, and the concentration of the microbubbles is hundreds of thousands or even more than millions. When the living water with micro bubbles is used for cleaning, the adhesion of impurities can be broken due to the micro physical characteristics and the surface tension of the micro bubbles, so that the impurities are easier to fall off from the surface of an object. In addition, as the micro bubbles collide with each other, break and fuse, impact is formed on the surface of the object, and impurities fall off and are flushed away or are carried by the bubbles to float on the water surface, so that a more thorough cleaning effect is achieved.

The existing water purifier system generally filters tap water through a first-stage filter element and then through a second-stage filter element, and the tap water directly reaches a water tap through a water flow branch. At this time, the domestic water can be directly taken out by opening the switch on one side of the tap. When the switch on one side of the faucet is closed and the switch on the other side is opened, the booster pump can be started when the water pressure switch detects that the pressure of water is reduced, and meanwhile, the electromagnetic valve is opened to allow water to pass through. Under the supercharging action of the booster pump, the reverse osmosis membrane filter core can separate pure water with very low salt content and concentrated water with higher salt content, the pure water passes through the one-way valve and then is filtered by the rear filter core, finally the pure water is discharged from the faucet, and the concentrated water is discharged to a sewer after passing through the flushing electromagnetic valve.

The water purifier 1000 according to the embodiment of the second aspect of the present invention includes the air mixing tank 100 according to the embodiment of the first aspect of the present invention described above.

According to the water purifier 1000 of the embodiment of the present invention, by providing the gas mixing tank 100 of the embodiment of the first aspect described above, the practicality and safety of the water purifier 1000 are improved.

In some embodiments, the water purifier 1000 includes: tap water inlet 1001, pre-filter 1002, pressure regulating valve 1003, water inlet ejector 1004, pre-solenoid valve 1005, booster pump 1006, gas mixing tank 100, first check valve 1007, second high-pressure switch 1008, micro-nano bubble generator 1009, domestic water outlet 10010, water inlet solenoid valve 10011, reverse osmosis filter 10012, flushing solenoid valve 10013, concentrated water outlet 10014, second check valve 10015, post-filter 10016, first high-pressure switch 10017, drinking water outlet 10018, air inlet 10019, air filter 10020, and third check valve 10021.

As shown in fig. 6, a pre-filter 1002, a pressure regulating valve 1003, a water inlet jet 1004 and a booster pump 1006 are connected in series on a water inlet channel 4001, a pre-electromagnetic valve 1005 is connected in series on a water inlet channel 5001, an air filter 10020 and a third check valve 10021 are connected in series on an air inlet channel 6001, a gas mixing tank 100, a first check valve 1007, a second high-pressure switch 1008 and a micro-nano bubble generator 1009 are connected in series on an air-water mixing channel 9001, a water inlet electromagnetic valve 10011, a reverse osmosis filter 10012, a second check valve 10015, a post-filter 10016 and a first high-pressure switch 10017 are connected in series on a water purifying channel 7001, and a flushing electromagnetic valve 10013 is connected in series on a concentrated water channel 8001.

Specifically, tap water enters the waterway system from the tap water inlet 1001, is filtered by the pre-filter 1002, and is split into two paths, one path reaches the booster pump 1006 through the pressure regulating valve 1003 and the water inlet ejector 1004, and the other path reaches the booster pump 1006 through the pre-electromagnetic valve 1005. After being pressurized by the booster pump 1006, the water flow is divided into two paths again, one path reaches the backflow mixing tank 100, and then reaches the domestic water outlet 10010 through the first one-way valve 1007 and the bubbler connector 1008. The other path of the water passes through the water inlet electromagnetic valve 10011 and then reaches the reverse osmosis filter element 10012, and the pure water and the concentrated water can be separated from the reverse osmosis filter element 10012. The concentrated water is discharged from the concentrated water outlet 10014 to the sewer after passing through the flushing solenoid valve 10013, and the purified water is filtered by the post filter element 10016 after passing through a second one-way valve 10015, and finally flows out from the drinking water outlet 10018.

When the user turns on the tap to activate water, the second high-pressure switch 1008 installed on the water path behind the first check valve 1007 will detect a pressure decrease of less than 0.5MPa, at which time the control system will start the booster pump 1006 to continuously perform the boosting operation. At the same time, the pre-solenoid valve 1005 and the water inlet solenoid valve 10011 will be closed, and at this time, the tap water passes through the pre-filter 1002, the pressure regulating valve 1003 and the water inlet ejector 1004 to reach the booster pump 1006, and then enters the gas mixing tank 100 through the second check valve 10015. Since a large amount of water flow can only pass through the water inlet ejector 1004 and then enter the booster pump 1006, the air inlet of the water inlet ejector 1004 will suck air synchronously, and the sucked air will enter the booster pump 1006 together with the water flow and then enter the air mixing tank 100. The pressure in the air mixing tank 100 will rise and air will be continuously dissolved in the water and then flow out of the outlet of the air mixing tank 100. After the water in which the air is dissolved passes through the micro-nano bubble generator 1009, the pressure of the water is reduced, the air is separated out from the water, a plurality of micron-sized bubbles are formed, and finally the air-dissolved water flows out from the water outlet of the faucet. When the user turns off the tap life level, the second high voltage switch 1008 will detect a pressure increase greater than 0.7MPa, at which point the system will turn off the booster pump 1006, stopping the system.

When the user turns on the tap purified water and turns off the living water, the first high-voltage switch 10017 installed on the water path of the post-filter element 10016 detects the pressure reduction of the water path, and the control system starts the booster pump 1006 to continuously perform the boosting operation. At the same time, the pre-solenoid valve 1005 and the water inlet solenoid valve 10011 on the water path will be opened, and at this time, the water passes through the pre-filter core 1002 and the pre-solenoid valve 1005 and reaches the booster pump 1006. The water pressurized by the booster pump 1006 enters the reverse osmosis filter element 10012 after passing through the water inlet electromagnetic valve 10011, and the pure water and the concentrated water are separated from the reverse osmosis filter element 10012. The concentrated water is discharged from the concentrated water outlet 10014 to the sewer after passing through the flushing solenoid valve 10013, and the purified water flows out from the faucet after passing through the post filter element 10016. When the user turns off the tap purified water, the system will turn off the booster pump 1006, the pre-solenoid valve 1005 and the water inlet solenoid valve 10011, stopping the system.

Preferably, the specification parameter of the pressure regulating valve 1003 is selected to be 0.1MPa, the booster pump 1006 is selected to be 300 gallons of booster pump 1006, and then the flow rate of water in the gas-water mixed flow is 2.0L/min, and the gas flow rate is 70mL/min.

In other embodiments, referring to fig. 26, the water purifier 1000 further includes: the pressure tank 10022, the fourth check valve 10023 and the second water inlet solenoid valve 10024, the water flow entering the air mixing jet 10 passes through the pre-filter core 1002, and the booster pump 1006 only supplies a small amount of air and water to the air return pipe 50 of the air mixing tank 100, so as to ensure the air flow required by the system in operation.

It should be noted that, in the first embodiment, the water purifier 1000 with a larger flow rate is applied to the booster pump 1006 itself, for example, the booster pump 1006 has a specification of 300 gallons or more. While the second embodiment is applicable to all specifications of booster pumps 1006, such as 50 gallon specifications of booster pumps 1006. However, in order to ensure the concentration of microbubbles of the water purifier 1000, the tap water pressure required in the present embodiment is greater than 0.2MPa, and the above embodiment is applicable to a case where the tap water pressure is small, for example, 0.1 MPa.
