Description

Technical Field

[0001] This utility model relates to the field of drinking water appliance technology, specifically to a water circuit and water outlet device for pre-treatment of residual water. Background Technology

[0002] Currently, drinking water equipment on the market undergoes water system testing (such as water pressure testing or water flow testing) before leaving the factory to ensure its sealing and functionality. During the testing process, a large amount of water may remain in the water system. Since the equipment is usually not powered on when it leaves the factory, its power source (such as the water pump) cannot start, preventing the water from being discharged through the normal drainage process. If shipped directly from the factory, the residual water may breed bacteria or cause corrosion of internal components, affecting the equipment's lifespan and hygiene safety. In addition, some manufacturers attempt to remove the water by blowing or sucking water, but due to limitations in the equipment's internal structure, such as the water pump being off, the presence of one-way valves in the water system, or obstructions such as valves, airflow or water flow cannot penetrate the entire water system, resulting in localized water accumulation that is difficult to remove and residual moisture remaining, preventing thorough drying. Especially for drinking water equipment with complex water system designs, the location of the power source may form a "dead water zone," further exacerbating the problem of incomplete drainage. Ultimately, this fails to meet high standards for production and storage.

[0003] Therefore, there is an urgent need to provide a water circuit and effluent device for pretreatment of residual water to solve the above-mentioned technical problems. Summary of the Invention

[0004] In response to the problems in related technologies, this utility model proposes a water circuit and water outlet device for pre-treatment of residual water, which solves the problem that the internal water circuit of drinking water equipment cannot completely remove accumulated or residual water when it leaves the factory.

[0005] This utility model is implemented as follows:

[0006] A water circuit for residual water pretreatment includes an inlet and an outlet; the inlet is connected to an outlet container; the direction from the inlet to the outlet is the outflow direction of the water circuit; a water flow power unit is connected to the water circuit; when the water flow power unit is working, the water circuit is connected, and when it stops working, the water circuit is disconnected; the power provided by the water flow power unit is in the same direction as the outflow direction.

[0007] The water path is also connected to a one-way flow channel; wherein, a one-way valve is connected to the one-way flow channel; both ends of the one-way flow channel are respectively connected to the water paths near the two ends of the water flow power unit; the flow direction of the one-way valve is the same as the flow direction of the outlet water.

[0008] A check valve, also known as a non-return valve, prevents backflow and leakage, ensuring unidirectional water flow and avoiding reverse leakage caused by level differences or power interruptions. By installing a check valve, the water circuit maintains a unidirectional flow even when interrupted. During factory cleaning, the water circuit undergoes a purging process to completely remove any residual liquid. Furthermore, during normal operation, the check valve prevents backflow, ensuring the overall normal flow direction of the water circuit.

[0009] Specifically, the above-mentioned water blowing process involves blowing air from the water inlet or drawing air from the water outlet.

[0010] As a further optimization of the above scheme, the waterway includes a main channel and several branch channels, and the branch channels are connected to the main channel;

[0011] The main channel is provided with at least one of the flow power units; the branch channels are provided with at least one of the flow power units; and the main channel is connected to a unidirectional channel at both ends of each of the flow power units.

[0012] "Several" refers to any number. Specifically, branch channels can be used to expand functionality; for example, the main channel can provide room temperature water, while branch channels can provide rapidly heated high-temperature water or rapidly cooled low-temperature water. Branch channels can be connected to unidirectional channels or not.

[0013] As a further optimization of the above scheme, the branch channel includes a wastewater channel; one end of the wastewater channel is connected to the main channel, and the other end extends to the wastewater tank.

[0014] Wastewater tanks are used to collect "wastewater" from cleaning the main channel.

[0015] As a further optimization of the above solution, a water valve for opening and closing the water flow is provided on the main channel; the water valve is located downstream of the connection between the wastewater channel and the main channel, and the water valve is close to the wastewater channel.

[0016] During routine use of the equipment, when the water circuit is disconnected by controlling the water valve, the water can flow to the wastewater circuit to achieve flushing and cleaning of the water circuit.

[0017] As a further optimization of the above scheme, the waterway is connected to the unidirectional flow channel via a tee.

[0018] Tees are also known as pipe tees, tee fittings, tee connectors, etc.

[0019] As a further optimization of the above scheme, the main flow channel is connected to the branch flow channel via a tee.

[0020] As a further optimization of the above scheme, the waterway is provided with a four-way connector; the four-way connector includes four ports, which are respectively connected to the water inlet, the water flow power unit, the unidirectional flow channel, and the branch flow channel.

[0021] As a further optimization of the above solution, the water flow power unit is a water pump.

[0022] This utility model also provides a water outlet device, which uses a water circuit for residual water pretreatment as described above.

[0023] As a further optimization of the above solution, the water outlet device includes a detachable kettle and a water outlet base, which are coupled together by a detachable hydro-electric coupler; the water circuit is located inside the water outlet device, and the water inlet is connected to the water receiving end of the water coupler.

[0024] The beneficial effects are as follows:

[0025] This utility model provides a water circuit and water outlet device for pretreatment of residual water. By setting a one-way flow channel and its one-way valve in parallel with the water flow power unit in the water circuit, it can realize the discharge of accumulated water when the equipment is not working, and maintain the complete function of the water circuit system when working normally, effectively solving the problem of residual water in the factory inspection and water blowing process.
