The water outlet 12 and the auxiliary water outlet 19 of the water outlet bin 1 are communicated with a water source through pipelines.
The principle of example 1 is briefly described in connection with the operation of an instant water dispenser:
as shown in fig. 3, when hot water is needed, an operator presses a water outlet key (not shown in the figure), the water pump 101 starts to pump water at a water source into the balance cavity 103, water in the balance cavity 103 enters the heating cavity 104 and the water outlet bin 1 through the one-way valve 106 and the water inlet 11 respectively, when the liquid level in the water outlet bin 1 reaches a preset height, the pontoon 4 floats upwards due to buoyancy of the water, meanwhile, the inner magnetic block 5 is driven to move upwards, the distance between the inner magnetic block and the outer magnetic block becomes far, the repulsive force exerted by the outer magnetic block 6 is weakened, when the repulsive force is weakened to be insufficient to keep the downward pressing state of the rocker 7, the rocker 7 is lifted to the initial position, the contact 82 of the micro switch 8 is immediately returned to the closed state, and the electric heater 102 is electrified.

All the overflowed water flows into the drain bin 1 after the liquid level of the balance cavity 103 reaches the highest level. The drain sump 1, the balance chamber 103, the heating chamber 104 and the water outlet chamber 105 are all at the same atmospheric pressure. When the water in the heating chamber 104 boils, it tumbles over the partition 107 and enters the water outlet chamber 105. The water inlet end of the water pump 101 is communicated with a water source, and the water outlet end of the water pump 101 is communicated with a water inlet at the lower end of the balance cavity 103.
The water outlet 12 and the secondary water outlet 16 of the water outlet bin 1 are communicated with a water source through pipelines.
The principle of example 2 is briefly described in connection with the operation of the instant water dispenser:
when hot water is needed, an operator presses a start key (not shown in the figure), the water pump 101 starts to pump water at a water source into the balance cavity 103, water in the balance cavity 103 enters the heating cavity 104 through the one-way valve 106, and after the balance cavity 103 is full, the water automatically overflows to the drainage bin 1. When the liquid level in the drainage bin 1 reaches a preset height, the pontoon 4 floats together with the inner magnetic blocks 5, the distance between the inner magnetic blocks and the outer magnetic blocks becomes long, the repulsive force borne by the outer magnetic blocks 6 is weakened, when the repulsive force is weakened to be insufficient to keep the downward pressing state of the rocker 7, the rocker 7 is lifted back to the initial position, the contact 82 of the micro switch 8 is immediately returned to the closed state, and the electric heater 102 is electrified.
When the pontoon 4 floats upwards, the sealing gasket 3 is separated from the sealing plate 2, and water in the upper cavity 13 of the drainage bin 1 falls into the lower cavity 14 of the drainage bin 1 through the water leakage hole 21 of the sealing plate 2 and is drained through the water drain outlet 12. At the same time, water overflowed from the balance chamber 103 is continuously replenished from the water inlet 11 of the drain bin 1 into the upper chamber 13 of the drain bin 1.
In order to keep the electric heater 102 continuously electrified, the pumping flow of the water pump 101 is set so that the water inflow in the unit time of the upper cavity 13 is larger than the water drainage in the unit time of the upper cavity 13, thus the liquid level of the upper cavity 13 is gradually raised, and when the water accumulated in the upper cavity 13 overflows through the secondary water drainage outlet 16, a part of water in the upper cavity 13 is drained through the secondary water drainage outlet 16, so that the water in the water drainage bin 1 is prevented from overflowing fully.
When hot water is not needed, an operator presses a stop key (not shown in the figure), the water pump 101 is powered off, the upper cavity 13 of the water discharge bin 1 is injected without water, and water in the upper cavity 13 is completely discharged into the lower cavity 14 through the water leakage hole 21 and then is discharged through the water discharge hole 12. At this time, the pontoon 4 and the sealing gasket 3 are tightly attached to the upper end surface of the sealing plate 2 under the action of the gravity of the inner magnetic block 5, the distance between the inner magnetic block and the outer magnetic block is shortest, the repulsive force applied to the outer magnetic block 6 is strongest, the repulsive force makes the rocker 7 switch to a pressed state, the contact 82 of the micro switch 8 is immediately switched to an off state, and the electric heater 102 is powered off.
