Description

Gas mixing tank and water purifier with same

Technical Field

The invention relates to the technical field of household appliances, in particular to a gas mixing tank and a water purifier with the same.

Background

In the related art, tap water is taken as inlet water of the water purifier, and direct drinking water or domestic water can be obtained by filtering through different filter elements. The drinking water of the water purifier reaches the level of pure water 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 domestic water can be used for most domestic purposes, such as washing fruits, vegetables and oil stains.

Domestic water of a water purifier on the market is generally filtered by a PP cotton filter element or an active carbon filter element, or is simultaneously filtered by the PP cotton filter element and the active carbon filter element, or is filtered by a composite filter element with the same function. Therefore, the water purifier has no other functions except general filtration, and the washing effect is very limited.

When the water purifier is used for taking domestic water, air is introduced into the backflow air mixing tank to mix air and water, so that micro bubbles are added to the domestic water in the effluent water, and the concentration of the micro bubbles is hundreds of thousands of even more than one million. When the living water with the micro bubbles is used for cleaning, due to the micro physical characteristics and the surface tension effect of the micro bubbles, the adhesion of impurities can be broken, so that the impurities are easy to fall off from the surface of an object. In addition, as the micro bubbles collide with each other, break and fuse with each other, impact is formed on the surface of the object, and impurities fall off and are washed away or float to the water surface under the driving of the bubbles, so that a more thorough cleaning effect is achieved.

As shown in fig. 1, the central axis of the first port 205 does not intersect the central axis of the canister 20. When the water in the water inlet 103 flows in at a high speed, the water at the bottom of the tank body 20 is driven to rotate in a vortex manner. Therefore, the gas-dissolved water is mixed more uniformly, and the gas mixing efficiency of the gas mixing tank 100 is improved.

In some embodiments of the present invention, the second port 206 is formed at a lower portion of the tank 20, a height position of the second port 206 in the vertical direction is lower than that of the first port 205, the baffle 60 is further disposed in the tank 20, the baffle 60 is horizontally disposed and located between the first port 205 and the second port 206, and a through hole penetrating through the baffle 60 in the thickness direction is disposed on the baffle 60. That is, the second port 206 is formed at the lower portion of the tank 20, the height of the first port 205 is higher than the height of the second port 206 in the vertical direction, the baffle 60 is horizontally disposed in the tank 20, the baffle 60 is located between the first port 205 and the second port 206, and the baffle 60 is further formed with a through hole penetrating the baffle 60 in the thickness direction.

In some embodiments of the present invention, a jet flow channel 101 and an air inlet channel 102 are formed in the air mixing ejector 10, a water inlet 103, a water outlet 104 and an air inlet 105 are formed on the air mixing ejector 10, and the jet flow channel 101 includes: a first pipe section 1011 having a first pipe section inlet 10111 and a first pipe section outlet 10112 and a second pipe section 1012 having a second pipe section inlet 10121 and a second pipe section outlet 10122, one end of the first pipe section 1011 extending to the water inlet 103 and one end of the second pipe section 1012 extending to the water outlet 104, the first pipe section inlet 10111 having a different cross-sectional flow area than the first pipe section outlet 10112, the second pipe section inlet 10121 having a different cross-sectional flow area than the second pipe section outlet 10122, one end of the inlet passageway 102 connected to the gas inlet 105 and the other end of the inlet passageway 102 extending between the first pipe section 1011 and the second pipe section 1012 and communicating with the jet passageway 101.

As shown in fig. 6, the jet flow channel 101 and the air inlet channel 102 are formed in the air mixing ejector 10, the water inlet 103, the water outlet 104 and the air inlet 105 are formed on the air mixing ejector 10, the jet flow channel 101 includes a first pipe section 1011 and a second pipe section 1012, one end of the first pipe section 1011 extends to the water inlet 103, one end of the second pipe section 1012 extends to the water outlet 104, the flow cross-sectional area of the first pipe section inlet 10111 is larger than that of the first pipe section outlet 10112, the flow cross-sectional area of the second pipe section inlet 10121 is larger than that of the second pipe section outlet 10122, one end of the air inlet channel 102 is connected to the air inlet 105, the other end of the air inlet channel 102 extends between the first pipe section 1011 and the second pipe section 1012, and the air inlet channel 102 is connected to the jet flow channel 101.

When the gas-mixing jet device 10 is used, water enters from the water inlet 103 of the gas-mixing jet device 10 and flows through the first pipe section 1011 of the jet channel 101, air is sucked from the air inlet 105 of the gas-mixing jet device 10 and enters the air inlet channel 102, then the air is mixed with the water, the gas-water mixture flows from the second pipe section 1012 of the jet channel 101 to the water outlet 104 and flows out from the water outlet 104, the gas-mixing jet device 10 is simple in structure and convenient to manufacture, the manufacturing cost is reduced, and the efficiency and the quality of the gas-water mixture are improved.

In some embodiments of the present invention, the fluidic channel 101 further comprises: a throat section 1013. The throat section 1013 is connected between the first pipe section 1011 and the second pipe section 1012, the other end of the intake passage 102 is connected to and communicates with the throat section 1013, and the flow cross section of the throat section 1013 is constant in the direction from the water inlet 103 to the water outlet 104. That is, a throat section 1013 is connected between the first pipe section 1011 and the second pipe section 1012, the other end of the intake passage 102 is connected to the throat section 1013, and the other end of the intake passage 102 communicates with the throat section 1013, and the flow cross section of the throat section 1013 is always constant. The fluidic channel 101 is simple in construction and easy to manufacture.

As shown in fig. 6, the lower end of the intake passage 102 communicates with the throat section 1013, the right end of the first pipe section 1011 of the jet passage 101 communicates with the left end of the throat section 1013, and the left end of the second pipe section 1012 of the jet passage 101 communicates with the right end of the throat, so that the flow cross section of the throat section 1013 is always constant in the left-to-right direction, and the air intake 105 of the air mixing jet device 10 is formed to have a negative pressure due to the venturi effect to suck air, whereby the structure of the air mixing jet device 10 is simple.

In some embodiments of the present invention, the end of the other end of the intake passage 102 is formed with an outlet hole 1021, and the aperture of the outlet hole 1021 is smaller than the inner diameter of the throat section 1013. That is, the outlet hole 1021 is formed at the end of the other end of the intake passage 102, and the inner diameter of the throat section 1013 is larger than the aperture of the outlet hole 1021. When the air mixing ejector 10 works, the air inlet 105 is in a negative pressure state, air is sucked, the aperture of the air outlet 1021 is small, and air entering the air mixing ejector 10 is reduced, so that excessive air inlet can be avoided, and water flow is prevented from being influenced.

In some embodiments of the present invention, the cross-sectional area of the other end of the intake passage 102 gradually decreases in a direction from one end toward the other end of the intake passage 102. That is, the cross-sectional area of the other end of the air inlet channel 102 far from the air outlet 1021 is larger than that of the other end of the air inlet channel 102 near the air outlet 1021, so that the flow rate of air is increased, and the amount of air dissolved in water is increased.

For example, as shown in fig. 6, the cross-sectional area of the lower end of the intake passage 102 gradually decreases in the top-down direction. Thus, the air-fuel mixture ejector 10 is simple in structure.

In some embodiments, the length of the first tube section 1011 is less than the length of the second tube section 1012 in a direction from the water inlet 103 towards the water outlet 104. That is, in the direction from the water inlet 103 to the water outlet 104, the length of the first pipe section 1011 is shorter, the length of the second pipe section 1012 is longer, and the length of the second pipe section 1012 is greater than the length of the first pipe section 1011. The length of the first pipe section 1011 is short, so that the flow velocity of water flow is increased rapidly, the flow velocity of water flow is increased, the length of the second pipe section 1012 is long, the accelerated water flow is buffered, and the damage to the gas mixing ejector 10 caused by overlarge pressure is avoided.

As shown in fig. 6, in the left-to-right direction, the length of the first pipe section 1011 is smaller, the length of the second pipe section 1012 is larger, and the length of the second pipe section 1012 is larger than the length of the first pipe section 1011. Therefore, the jet flow channel 101 of the gas mixing jet device 10 is ingenious in design, and the use feeling of a user is improved.

In some embodiments of the invention, the central axis of the jet passage 101 extends in a first direction and the centerline axis of the inlet passage 102 extends in a second direction perpendicular to the first direction. That is, the central axis of the jet flow passage 101 may extend in a horizontal direction, the central axis of the intake passage 102 may extend in a vertical direction perpendicular to the horizontal direction, the central axis of the jet flow passage 101 may also extend in a vertical direction, and the central axis of the intake passage 102 may extend in a horizontal direction perpendicular to the vertical direction. Therefore, the jet flow channel 101 and the air inlet channel 102 of the air-mixed ejector 10 are simple in structure and convenient to manufacture.

As shown in fig. 6, the central axis of the jet flow passage 101 extends in the horizontal direction, the central axis of the air intake passage 102 extends in the vertical direction perpendicular to the horizontal direction, water enters from the water inlet 103 of the jet flow passage 101 extending in the horizontal direction, reaches the throat section 1013, and air is sucked from the air inlet 105 of the air intake passage 102 in the vertical direction, reaches the throat section 1013, is mixed with the water, and then flows out from the water outlet 104 of the jet flow passage 101.

In some embodiments of the invention, the cross-sectional flow area of the first tube section 1011 decreases and the cross-sectional flow area of the second tube section 1012 increases in a direction from the water inlet 103 towards the water outlet 104.

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

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

A water purifier according to two specific embodiments of the present invention will be described with reference to fig. 1 to 18.

In a first embodiment, as shown in fig. 17, a water purifier 1000 includes: the system comprises a tap water inlet 1001, a preposed filter element 1002, a pressure regulating valve 1003, a water inlet ejector 1004, a preposed electromagnetic valve 1005, a booster pump 1006, a gas mixing tank 100, a first one-way valve 1007, a second high-pressure switch 1008, a bubbler joint 1009, a domestic water outlet 10010, a first water inlet electromagnetic valve 10011, a reverse osmosis filter element 10012, a flushing electromagnetic valve 10013, a concentrated water outlet 10014, a second one-way valve 10015, a postposition filter element 10016, a first high-pressure switch 10017, a drinking water outlet 10018, an air inlet 10019, an air filter element 10020 and a third one-way valve 10021.

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

When a user opens the water faucet to make running water, the second high-pressure switch 1008 arranged on the water path behind the first check valve 1007 detects that the pressure is reduced to be less than 0.5MPa, and at the moment, the control system starts the booster pump 1006 to continuously boost the water. At the same time, the prepositive electromagnetic valve 1005 and the first water inlet electromagnetic valve 10011 are closed, and then the tap water passes through the prepositive filter element 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 one-way valve 10015. Since a large amount of water flow enters the booster pump 1006 only after passing through the water inlet ejector 1004, the air inlet of the water inlet ejector 1004 sucks air synchronously, and the sucked air enters the booster pump 1006 together with the water flow to be boosted and then enters the air mixing tank 100. The pressure in the air mixing tank 100 will rise and the air will be constantly dissolved in the water and will flow out of the outlet of the air mixing tank 100. After the water with dissolved air passes through the bubbler connector 1009, the pressure of the water is reduced, the air is separated out of the water to form a plurality of micron-level bubbles, and finally the dissolved air water flows out of the water outlet of the faucet. When the user closes the faucet life level, the second high pressure switch 1008 will detect an increase in pressure, greater than 0.7MPa, at which point the system will shut down the booster pump 1006, causing the system to stop working.

When the user turns on the tap pure water and turns off the living water, the first high pressure switch 10017 installed on the water path of the rear filter element 10016 will detect that the pressure of the water path is reduced, and at this time, the control system will start the booster pump 1006 to continuously boost the water. At the same time, the solenoid valve 1005 and the first inlet solenoid valve 10011 on the waterway are opened, and then the water reaches the booster pump 1006 after passing through the pre-filter element 1002 and the solenoid valve 1005. The water pressurized by the booster pump 1006 enters the reverse osmosis membrane cartridge after passing through the first water inlet solenoid valve 10011, and the reverse osmosis cartridge 10012 separates purified water and concentrated water. The concentrated water passes through the flushing solenoid valve 10013 and is discharged from the concentrated water outlet 10014 to a sewer, and the purified water passes through the post-filter 10016 and flows out from the faucet. 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 first water inlet solenoid valve 10011, and stop the system.

In a second embodiment, as shown in fig. 18, in the second embodiment, the water purifier 1000 further includes: the pressure tank 10022, the fourth check valve 10023, and the second water inlet solenoid valve 10024 are substantially the same as the first embodiment, wherein the same components are denoted by the same reference numerals, and the differences are only: in the first embodiment, the water flow entering the gas-mixed ejector 10 is the water flow pressurized by the booster pump 1006, while in the second embodiment, the water flow entering the gas-mixed ejector 10 passes through the pre-filter element 1002, and the booster pump 1006 only supplies a small amount of gas and water to the return gas pipe 50 of the gas-mixed tank 100, so as to ensure the gas flow required by the system operation.

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