The main controller 1 is electrically connected with loads such as the water suction pump 3, the water inlet electromagnetic valve 5 and the instant heating assembly 6 through internal connecting wires, and the internal control program logic is used for controlling all the loads, so that the control functions of different states of the machine are realized.
The balance water tank 2 mainly comprises a mechanical floating ball, a high-low gear electronic liquid level switch and a tank body, wherein the mechanical floating ball is a last water inlet waterway switch of the balance water tank, and can ensure that the protection function of closing the water source safety is achieved when the waterway switch at the front end fails; the electronic liquid level switch with high and low gears is mainly used for inputting a water level identification signal to the main controller 1 after identifying the water level of the balance water tank, and when the liquid level switch is switched on at a low water level, the machine can realize water shortage protection alarm to prevent the situation of no water dry burning; when the high water level of the liquid level switch is switched on, the main controller 1 receives a high water level signal and then controls the water inlet electromagnetic valve 5 to be closed to cut off the water inlet waterway; the type of the liquid level switch is not limited to a dry reed type liquid level switch installed in a balanced water tank, and the liquid level switch can also be a capacitive liquid level switch installed on the outer wall of the water tank; the box mainly used stores the pure water, realizes the effect of pure water buffering, ensures that the instant heating subassembly has sufficient pure water source.
The water pump 3 is used to pump water from the balance tank 2 to the instant heating assembly 6. Because there is not pressure differential in the pipeline water dispenser, the pure water in the balanced water tank 2 needs to be heated in the instant heating subassembly 6 through the pump 3 with pure water pumping, then flows out through the delivery port, can realize the control of the water yield through the regulation to the pump 3 voltage size.
The water inlet electromagnetic valve 5 is a control switch of a pure water inlet pipeline, when the water level of pure water in the balance water tank 2 inside the machine reaches a high water level, the water source is cut off by the water inlet electromagnetic valve 5, a pipe connector at the front end of the balance water tank 2 can be guaranteed not to bear water pressure, and water leakage risk is reduced.
The service condition of the instant heating assembly 6 is 220V to 50Hz, and the control of the heating power of the instant heating assembly 6 is realized by controlling the on-off frequency of the controllable silicon through the main controller 1, so that the selection of different water temperatures of the outlet water can be realized, and the heating water temperature can be accurately 1 ℃.

The internal connecting wire mainly comprises a low-voltage wire and a high-voltage wire; the pipeline used at the front end of the balance water tank 2 is a PE pipe, because the pipeline at the front end of the balance water tank 2 has no high temperature (the PE pipe does not have high temperature resistance); the pipeline at the rear end of the balance water tank 2 is mainly a silicone tube, and the silicone tube is used for conveying high-temperature water because the silicone tube has better high-temperature resistance, so that the silicone tube is selected.
The pipeline water dispenser that this embodiment provided, its detection principle that leaks is as follows:
1. when the pipeline water dispenser normally works, pure water enters the balance water tank through the water inlet electromagnetic valve, when the water level of the balance water tank reaches the high water level of the liquid level switch, the main controller controls the water inlet electromagnetic valve to close to stop water inlet, when a user starts the machine to receive water, the water suction pump starts to pump water, the pure water in the balance water tank is pumped into the instant heating assembly through the water suction pump to be heated, and then the hot water flows to the water outlet through the water-vapor separation box after water-vapor separation.
2. When the whole machine fetches water, the water suction pump starts to pump water immediately, the water inlet electromagnetic valve is opened when the water pumping time of the water suction pump reaches a set value, the balance water tank starts to replenish water, and the electromagnetic valve is closed when the water is replenished to a high water level to stop replenishing water.
3. As shown in fig. 3, when no person takes water from the whole machine (the water pump is not started), and the main controller detects that the liquid level switch begins to fall and is finally at a low water level (the low water level switch is turned on), it is determined that water leaks from the whole machine, the interaction interface is triggered to start the water leakage protection alarm function, at this time, the water inlet electromagnetic valve and the instant heating component and other loads are all turned off, the whole machine stops working, and meanwhile, the user is reminded to remove the fault through audible and visual alarm.
4. The normal working state can be recovered only by electrifying again after the fault is eliminated, and the water leakage alarm function is still displayed by electrifying again when the fault is not eliminated, so that the safety of the whole machine can be ensured.
The pipeline water dispenser provided by the embodiment realizes the water leakage protection function mainly by judging the state change of a liquid level switch in a balancing water tank and the working state of a water pump; more than ninety-five percent of water of the pipeline water dispenser is stored in the balance water tank, no matter which part of the pipeline water dispenser leaks water, the water source of the leaking water all comes from the balance water tank, a liquid level switch in the balance water tank can change along with the change of the water level when leaking water, and in addition, the condition of detecting the working state of the water pump can accurately, comprehensively and effectively monitor whether the machine leaks water or not, and meanwhile, the defect of the water leakage chip detection water leakage protection function principle can be effectively overcome, so that the safety performance of the pipeline water dispenser is greatly improved.
