Please refer to FIG. 4 to FIG. 5 , which is another safe drinking water system 1a with automatic water supply according to the present invention, which is used for supplying boiling water and warm water, and the difference from the above drinking water system is: in the hot water tank 20 The water tank 30 is connected to the hot water tank 20 by a connecting pipe 31. The water tank 30 is provided with a one-way valve 32 at the top, and one outer periphery of the water tank 30 is provided. a water opening switch 33, a third water level switch 34 that can be raised and lowered with the water level, and a second temperature control switch 37 that senses the water temperature are electrically connected to the controller 50, wherein the The three water level switch 34 controls the heating device 132 to heat the hydration, and the third water level switch 34 must be disposed lower than the connecting pipe 31.

In particular, the open water tank 30 of the present invention can further add more than one cold water bucket, electrolysis water bucket or ice water bucket in series, and the additional ice water buckets can be filled with ice water to make the drinking water system of the present invention use. The expansion is extremely efficient and has multiple variations. Therefore, the hot water tank 20, the water tank 30 or/and the ice water bucket of the present invention are further connected to a water outlet device 40 at the water outlet, and the boiling water of the hot water tank 20 and the water tank 30 is boiled by means of water pressure regulation. The boiled water or the cold water and the ice water can be taken out through the water discharge device 40 for human consumption. Alternatively, warm water and cold water are discharged from the water discharge device 40 for drinking, and the hot water is discharged from an electronically controlled water discharge device 41 for drinking, as shown in Fig. 5-1.

Therefore, in the normal use condition of the drinking water system 1, 1a of the present invention, the raw water process is automatically introduced. As shown in FIG. 2 and FIG. 6, the raw water system 122 introduces clean raw water into the raw water tank 10, when the raw water is used. When the water level of the water tank 10 is located between the stop water inlet position P2 and the anti-dry position P3, the water inlet pipe 12 will continue to continuously introduce raw water from the water inlet system 122. Until the position of the magnetic float ball 111 reaches the stop water inlet position P2, the pumping is stopped after the corresponding reed switch 112 senses.

Under normal use conditions, the automatic refilling process of the drinking water system 1, 1a of the present invention, as shown in FIG. 2 and FIG. 6, is that the raw water in the raw water tub 10 is heated through the heating line 13 to enter the heat. In the water tub 20, when the raw water is introduced into the heating line 13, the raw water stays in the heating line 13 and the water does not flow back to the raw water tank 10 due to the blocking of the check valve 131, so the heating device 132 can be targeted The raw water remaining in the heating line 13 is heated to become boiling water and water vapor, and is discharged from the hot water tank 20 by the nozzle 133 until the second water level switch 25 reaches a predetermined water level, and then the heating line 13 is stopped. Heating hydration.

The drinking water system 1, 1a of the present invention can be used for the principle of raw water preheating. As shown in FIG. 2 and FIG. 3, the nozzle 133 flows out as a mixture of boiling water and water vapor, and the water vapor causes the internal pressure of the hot water tank 20 to increase. The check valve 22 is closed by pressure, so that water vapor will enter the condensing pipe 14 having a small internal pressure, and the water vapor can transmit heat through the condensing pipe 14 and add raw water to the raw water tank 10. Warming, the preheating effect is generated, so that the raw water inside the raw water tub 10 has started to heat up before heating, and when it enters the heating line 13, the heating time of the heating device 132 can be shortened, thereby achieving energy saving. purpose.

The drinking water system 1, 1a of the present invention creates a pressureless and waterless steam design which is completely different from the conventional structure. As shown in FIG. 2 and FIG. 3, the water vapor of the hot water tank 20 can contact the raw water tank via the condensation pipe 14. The cold water condenses the water vapor into a liquid and flows into the raw water tub 10, and the hot air is discharged from the other place (for example, a drain and a drain) by the drain pipe 114, thereby creating an environment in which the steam is not used to avoid harm to the environment. device. At the same time, when the second water level switch 25 and the first water level switch are both disabled, the water filled out by the hot water tank 20 and the water tank 10 can be smoothly discharged from the condensation tube 14, the water tank 10 and the drain pipe 114, and The water level of the magnetic float ball 111 is raised to the emergency power-off position P1, and the corresponding power supply is turned off by the corresponding reed switch 112, so that the hot water tank 20 and the water tub 10 may be prevented from bursting.

The reheating and heat preservation process of the drinking water system 1, 1a of the present invention, as shown in FIG. 2 and FIG. 6, the two first temperature control switches 26 disposed in the hot water tank 20 can detect the boiling water temperature in the barrel at any time, when boiling water When the temperature is lower than the set temperature of one of the two first temperature control switches 26, the heat retention heating unit 24 is also heated to warm the water temperature of the hot water tank 20, and stops when the boiling water temperature reaches a predetermined temperature. The heat of the heat retention assembly 24 is heated.

If the drinking water system 1, 1a of the present invention encounters an abnormal condition that the water inlet pipe 12 cannot continue to enter the water due to the failure of the pumping motor or the solenoid valve 121, the water level of the raw water tub 10 gradually decreases, and when the magnetic floating ball 111 reaches the When the dry floating position P3 is prevented, the magnetic floating ball 111 will be inductively reacted with the corresponding reed switch 112, and the heating device 132 is turned off to avoid drying the water inside the heating line 13 and avoiding fire. harm.

When the drinking water system 1, 1a of the present invention encounters an abnormal condition in which the first water level switch 11, the second water level switch 25 or/and the third water level switch 34 are damaged and fails, and cannot reliably measure the water level, as shown in FIG. The heating line 13 will be continuously heated and continuously supplied with boiling water, so when the hot water tank 20 is full of water level, the boiling water will be returned from the condensing pipe 14 to the raw water tank 10 due to the emergency shutdown of the first water level switch 11. When the electric position P1 is invalid, the water filled out by the hot water tank 20 and the raw water tank 10 can be smoothly discharged from the condensation pipe 14, the raw water pipe 10 and the discharge pipe 114, and the danger of the hot water tank 20 and the raw water tank 10 bursting can be avoided. . In this way, through the multi-layered protection design, the user's safety can be guaranteed.
