Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and relates to a combined water circuit structure for a pure water machine. Background Technology

[0002] With increasingly severe water pollution, urban water safety has become a prominent issue. To address secondary pollution of tap water and the presence of harmful substances in tap water due to raw water contamination, water purifiers are increasingly being used. Current household water filtration primarily utilizes RO (reverse osmosis) water purifiers, which treat municipal tap water through a coarse filtration system and RO reverse osmosis filtration to produce potable water. There are currently two types of water purifiers: RO machines that directly output water after passing through a coarse filtration system and RO reverse osmosis filtration, and integrated water purifiers and water heaters that can also provide hot water. However, existing water circuit structures are relatively complex and installation is not flexible or convenient. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a combined water circuit structure for a pure water machine that is simple and reasonable in structure and flexible and convenient to install, in view of the above-mentioned technical status.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a combined water circuit structure for a pure water machine, characterized in that it includes an RO filter water circuit board, a composite filter water circuit board, and an inlet / outlet water circuit board. The RO filter water circuit board is directly injection molded as a single piece. The RO filter water circuit board and the RO filter adapter plate are combined to form an RO water circuit assembly. The inlet / outlet water circuit board is formed by welding two water circuit boards. The inlet / outlet water circuit board, the composite filter water circuit board, the composite filter adapter plate, and corresponding electrical components are combined to form a composite filter water circuit assembly. The RO filter water circuit board, the composite filter water circuit board, and the inlet / outlet water circuit board are combined to form the RO machine water circuit structure.

[0005] Further improvements include a temperature-regulating water circuit board, which is formed by welding two water circuit boards, one above the other. The temperature-regulating water circuit board and corresponding electrical components are combined to form a combined temperature-regulating assembly. Based on the RO machine water circuit structure consisting of the RO filter water circuit board, the composite filter water circuit board, and the inlet and outlet water circuit boards, the temperature-regulating water circuit board is combined to form the water circuit structure of the integrated water purification and heating machine.

[0006] As an improvement, the RO filter adapter plate is fixedly connected to the RO filter water circuit board, and the RO filter water circuit board is connected to the RO filter through the RO filter adapter plate.

[0007] As an improvement, the composite filter water circuit board is fixedly connected to the composite filter adapter plate. The composite filter is composed of a pre-filter and a post-filter. The composite filter water circuit board is connected to the composite filter through the composite filter adapter plate and connected to the RO filter through the inlet and outlet water circuit boards.

[0008] As an improvement, the inlet / outlet water circuit board is provided with at least a raw water inlet, a raw water outlet, and a first pure water outlet. The raw water inlet is connected to the tap water pipeline, the raw water outlet is connected to the raw water inlet of the composite filter water circuit board, and the first pure water outlet is connected to the water tap. The inlet / outlet water circuit board is also provided with a pure water inlet interface and a raw water outlet interface connected to the RO filter water circuit board. The other end of the raw water outlet interface is connected to the inlet of the pre-filter of the composite filter, and the other end of the pure water inlet interface is connected to the inlet of the post-filter of the composite filter. If the inlet / outlet water circuit board opens a second pure water outlet, the second pure water outlet is connected to the cold water inlet of the temperature-regulating water circuit board.

[0009] Furthermore, the temperature control assembly also includes a first one-way valve, a water tank inlet solenoid valve, a low-pressure switch, a hot water outlet solenoid valve, and a temperature probe. The first one-way valve, the water tank inlet solenoid valve, and the low-pressure switch are installed on the water tank inlet pipe, while the hot water outlet solenoid valve and the temperature probe are installed on the water tank hot water outlet pipe. The temperature control circuit board is provided with a hot water outlet connected to a hot water faucet.

[0010] Furthermore, the water tank is also connected to a steam discharge pipe, which is connected to the concentrate outlet pipe of the RO filter element. The steam discharge pipe is equipped with a second one-way valve and a normally open valve.

[0011] Furthermore, the RO filter element water circuit board is provided with interfaces that connect and communicate with the inlet and outlet of the RO filter element, as well as a corresponding interface that communicates with the inlet of the post-filter element of the composite filter element. A booster pump, an inlet solenoid valve, a raw water quality tester, and a temperature probe are installed on the pipeline between the outlet of the RO filter element and the outlet of the pre-filter element. A third check valve and a flow meter are installed on the pipeline between the outlet of the RO filter element and the inlet of the post-filter element.

[0012] Finally, the inlet and outlet water circuit board also includes a return pipe. One end of the return pipe is connected to the pipe between the booster pump and the water quality tester, and the other end is connected to the pipe between the third check valve and the RO filter. A fourth check valve and a return solenoid valve are provided on the return pipe.

[0013] Compared with existing technologies, the advantages of this invention are as follows: the RO filter water circuit board is directly injection molded into one piece; the composite filter water circuit board and the inlet / outlet water circuit board are respectively welded from upper and lower water circuit boards; the temperature regulating water circuit board is also welded from upper and lower water circuit boards. During installation, these four water circuit boards are combined to form the integrated water circuit structure of the air purifier and heat pump; removing the temperature regulating water circuit board completes the RO machine water circuit structure. This invention has a simple and reasonable structure, is easy and flexible to assemble, and can simultaneously meet the assembly requirements of both the integrated air purifier and heat pump and the RO machine, while effectively reducing costs.
