Description

Technical Field

[0001] The present invention relates to the technical field of water purification devices, and particularly to a dual-outlet module assembly and a water purifier. Background Art

[0002] Water purifiers are widely used in people's daily lives. In particular, large-flow water purifiers are very popular among users. However, most of the existing water purifiers are in a single-outlet mode, that is, they generally can only produce pure water. Therefore, a large-flow water purifier with dual outlets is more suitable for people's usage scenarios. It can not only provide pure water, but also has pre-filtered water from the pre-filter element, which can provide clean, hygienic and safe water for washing vegetables, rinsing rice, cleaning, etc. for users without the need for power supply, realizing the function of dual use of one machine. However, it is difficult to transform a single-outlet water purifier, and after the existing water purifier has not been used for a long time, the TDS value of the first pure water taken out is likely to be too high, which is not conducive to human health. Summary of the Invention

[0003] The present invention provides a dual-outlet module assembly and a water purifier, which can reduce the overall machine transformation cost and solve the problem that the water purifier can only produce single water.

[0004] In a first aspect, the present invention provides a dual-outlet module assembly, including a water circuit board. Along the water flow direction on the water circuit board, a first filter element and a second filter element are sequentially connected in communication. A detachable module body is provided on the water circuit board. The module body has a purified water channel and a pure water channel. The water inlet end of the purified water channel is connected to the water outlet end of the first filter element. The water outlet end of the purified water channel is communicated with a purified water outlet. The water inlet end of the pure water channel is connected to the water outlet end of the second filter element. The water outlet end of the pure water channel is communicated with a pure water outlet.

[0005] In an embodiment, the water outlet of the second filter element is further communicated with a return branch. The pipeline between the first filter element and the second filter element is communicated with the return branch. A first check valve and a first solenoid valve are provided on the return branch. Through this embodiment, the pure water obtained after passing through the second filter element is mixed with the purified water that has passed through the first filter element through the return branch, and then pressurized by a pressure stabilizing pump and enters the second filter element again for filtration. Since the TDS value of the pure water is relatively low, after mixing with the purified water, the TDS value of the raw water before entering the second filter element can be greatly reduced. By the pure water reflux, the inside of the second filter element is flushed, thus solving the problem that the TDS value of the first cup of water taken out is too high when the water purifier has not been used for a long time, ensuring water use safety and better water quality.

[0006] In an embodiment, a second solenoid valve and a pressure stabilizing pump are arranged on the pipeline connecting the first filter element and the second filter element.

[0007] In one embodiment, a concentrated water discharge pipe is also connected to the second filter element, and a third solenoid valve is arranged on the concentrated water discharge pipe. Through this embodiment, the concentrated water generated by the second filter element can be discharged in time.

[0008] In one embodiment, the first filter element is a composite filter element, and the second filter element is a reverse osmosis filter element.

[0009] In one embodiment, a boss is arranged on the module body, a through hole is formed through the boss, and the module body is connected to the water circuit board through a screw penetrating through the through hole. Through this embodiment, the module body and the water circuit board are connected by screws, which can facilitate their quick disassembly and installation and is convenient for maintenance and replacement.

[0010] In one embodiment, a second check valve is arranged in the pure water channel.

[0011] In one embodiment, an installation hole is arranged at a position between the water inlet end and the water outlet end of the pure water channel, the second check valve is installed into the pure water channel through the installation hole, and the installation hole is provided with a detachable end cover. Through this embodiment, it is convenient to install the second check valve into the pure water channel, and the end cover can play an auxiliary positioning role for the second check valve.

[0012] In one embodiment, the purified water channel is provided with a valve. Through this embodiment, the opening and closing of the purified water channel can be controlled according to the usage requirements.

[0013] In a second aspect, the present invention provides a water purifier, including the dual-outlet module assembly as described above.

[0014] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the object of the present invention can be achieved.

[0015] A dual-outlet module assembly and a water purifier provided by the present invention, compared with the prior art, at least have the following beneficial effects:

[0016] By adopting a modular assembly with dual outlets and installing it at the first filter element and second filter element branch paths in the original water circuit board, without changing the structure and water circuit channels of the existing water circuit board, the overall machine transformation cost can be reduced, the production efficiency can be improved, and at the same time, it can meet the user's demand for domestic water and solve the problem that large-flow water purifiers can only have a single outlet.

[0026] Embodiment 1

[0027] As Figure 1 shown, the present invention provides a dual-outlet module component, including a water circuit board 10. A first filter element 50 and a second filter element 60 are sequentially connected in communication along the water flow direction on the water circuit board 10. A detachable module body 20 is provided on the water circuit board 10. The module body 20 has a purified water channel 21 and a pure water channel 22. The water inlet end of the purified water channel 21 is connected to the water outlet end of the first filter element 50, and the water outlet end of the purified water channel 21 is communicated with a purified water outlet 211. The water inlet end of the pure water channel 22 is connected to the water outlet end of the second filter element 60, and the water outlet end of the pure water channel 22 is communicated with a pure water outlet 221.

[0028] Specifically, Figure 1 the arrow symbol in

[0029] In one embodiment, the water outlet of the second filter element 60 is further communicated with a return branch 70. The pipeline between the first filter element 50 and the second filter element 60 is communicated with the return branch 70. A first check valve 72 and a first solenoid valve 71 are arranged on the return branch 70. Through this embodiment, the pure water obtained after passing through the second filter element 60 is mixed with the purified water that has passed through the first filter element 50 through the return branch 70, and then pressurized by a pressure stabilizing pump 82 and enters the second filter element 60 again for filtration. Since the TDS value of the pure water is relatively low, after being mixed with the purified water, the TDS value of the raw water before entering the second filter element 60 can be greatly reduced. Through the return of the pure water, the inside of the second filter element 60 is flushed, thus solving the problem that the TDS value of the first glass of water is too high when the water purifier is not used for a long time, and ensuring the safety of water use and better water quality.

[0030] Specifically, by setting the first check valve 72, it is possible to avoid the problem that the purified water obtained after passing through the first filter element 50 directly enters the pure water outlet 221 without passing through the filtration of the second filter element 60 during the process of entering the second filter element 60. When the first solenoid valve 71 is in the closed state, the return flow stops, and the pure water obtained after passing through the second filter element 60 directly flows to the pure water outlet 221.

[0031] In one embodiment, a second solenoid valve 81 and a pressure stabilizing pump 82 are arranged on the pipeline connecting the first filter element 50 and the second filter element 60.

[0032] Specifically, by opening and closing the second solenoid valve 81, it is possible to determine whether to activate the second filter element 60 according to the user's usage requirements. By setting the pressure stabilizing pump 82, it is ensured that the water flow can flow normally.

[0033] In one embodiment, the second filter element 60 is further communicated with a concentrated water discharge pipe 61, and a third solenoid valve 62 is arranged on the concentrated water discharge pipe 61. Through this embodiment, the concentrated water generated by the second filter element 60 can be discharged in time.

[0034] In one embodiment, the first filter element 50 is a composite filter element, and the second filter element 60 is a reverse osmosis filter element, that is, an RO membrane filter element.

[0035] As Figure 2 and 3 shown, in one embodiment, a boss 30 is arranged on the module body 20, and a through hole 31 is formed through the boss 30. The module body 20 is connected to the water circuit board 10 through a screw 32 passing through the through hole 31. Through this embodiment, the module body 20 and the water circuit board 10 are connected by the screw 32, which can facilitate their quick disassembly and installation and is convenient for maintenance and replacement.

[0036] Specifically, a cylinder is provided on the waterway board 10, and a threaded hole coaxial with the via hole 31 is provided on the cylinder.

[0037] In one embodiment, a second check valve 40 is provided in the pure water channel 22.

[0038] Specifically, the second check valve 40 is used to prevent the pure water from flowing back reversely when the user closes the faucet without taking the pure water, and then stops the machine from making water by the pressure switch provided in the whole machine.

[0039] As Figure 4 shown, the arrow symbols in the figure are the moving directions of the water flow in the purified water channel 21 and the pure water channel 22 respectively. In one embodiment, an installation hole is provided at the part between the water inlet end and the water outlet end of the pure water channel 22, and the second check valve 40 is installed into the pure water channel 22 through the installation hole, and the installation hole is provided with a detachable end cover. Through this embodiment, it is convenient to install the second check valve 40 into the pure water channel 22, and the end cover can play an auxiliary positioning role for the second check valve 40.

[0040] Specifically, a limiting step is provided inside the pure water channel 22. After the second check valve 40 is placed into the pure water channel 22, the limiting step cooperates with the end cover to realize the fixation of the second check valve 40. Further, the end cover and the housing module body 20 are fastened by ultrasonic welding, hot plate welding, threaded connection or snap connection, etc. A sealing ring for assembling and sealing with the waterway board 10 is also assembled on the pure water channel 22 to prevent water leakage.

[0041] In one embodiment, the purified water channel 21 is provided with a valve. Through this embodiment, the opening and closing of the purified water channel 21 can be controlled according to the usage requirements.

[0042] Specifically, a sealing ring and a gland for ultrasonic welding, hot plate welding or clamping, etc. with the cylinder for forming the purified water channel 21 are assembled in the inner cavity of the purified water channel 21, and the claw is assembled into the gland to prevent the module body 20 from falling off due to water pressure after the module body 20 is connected to the purified water outlet.
