For the heating device 104 heated by the heating tank 1, the warm water tank 2 is provided with a warm water tank temperature sensor 201 and a warm water tank liquid level sensor 202; 103. The warm water tank temperature sensor 201, the warm water tank liquid level sensor 202, the first solenoid valve 4, the second solenoid valve 6 and the third solenoid valve 7 are all electrically connected to the control circuit.

The drinking water supply device of the present embodiment is provided with a first electromagnetic valve 4 on the water inlet pipe that communicates with the heating tank 1. The opening and closing of the first electromagnetic valve 4 is controlled by the control circuit, and the first electromagnetic valve 4 is opened to start injecting cold water. After a certain amount of cold water is injected into the heating box 1, the first electromagnetic valve 4 is closed, and the cold water in the heating box 1 can be heated at this time. , and there will be no cold water mixed in, thereby preventing the cold water from being injected into the heating box 1 to produce a mixture of cold and hot water (yin and yang water); secondly, only when all the hot water in the heating box 1 is drunk, or the heating box 1 After the water in the tank has been cooled for a period of time and all flows into the warm water tank 2, the first solenoid valve 4 will start to inject water into the heating tank 1, and the heating device 104 will be started to heat after injecting cold water, so there will be no empty heating conditions, while reducing the consumption of electric energy to a certain extent; The temperature of the hot water drops to a certain temperature (85°C).

By controlling the heating The amount of heated hot water in the box 1 can reduce excessive waste caused by one-time drinking.

Wherein, the warm water tank liquid level sensor 202 can be arranged on the top of the warm water tank 2 (close to the position of the upper tank mouth of the warm water tank 2).

In this embodiment, the control circuit includes an MCU (Microcontroller Unit, micro control unit), an acquisition circuit, a control output circuit and a timing circuit; the MCU is connected to the acquisition circuit, the control output circuit and the timing circuit.

Specifically, the MCU controls the acquisition circuit to acquire temperature signals, liquid level signals, and state signals of the flowmeter 5 and the solenoid valve in real time. When the warm water tank liquid level sensor 202 had no water level signal, the second electromagnetic valve 6 was opened, and if the flow meter 5 had no water flow signal, the second electromagnetic valve 6 was closed; (It should be noted that here, when the warm water tank liquid level When the sensor 202 has no water level signal, the second electromagnetic valve 6 is opened, and if the flow meter 5 has no water flow signal, the second electromagnetic valve 6 is closed. The purpose of this setting is to ensure that there is still a certain water holding space in the warm water tank 2 on the one hand. On the other hand, ensure that all the water in the heating tank 1 flows into the warm water tank 2, avoiding reheating the hot water in the heating tank 1, that is, avoiding processing thousands of boiling water.) At this time, the MCU opens the first A solenoid valve 4, start the heating device 104 at the same time, close the first solenoid valve 4 when the liquid level sensor 102 on the heating box collects the water level signal, and close the first solenoid valve 4 when the water temperature in the heating box 1 reaches the set temperature threshold (such as: 95 ° C) Close the heating device 104 at the time, and set the holding time by the timing circuit as t (wherein, t is the time required for the water temperature to drop from 95°C to 85°C according to the water capacity in the water dispenser heating box 1).

If within the time t, when the liquid level sensor 103 under the heating tank collects the water level signal, the second electromagnetic valve 6 is opened, and if the flow meter 5 has no water flow signal, the second electromagnetic valve 6 is closed. At this time, the MCU controls the output circuit Open the first solenoid valve 4, start the heating device 104 at the same time, close the first solenoid valve 4 when the liquid level sensor 102 on the heating tank collects the water level signal, and turn off the heating device when the water temperature in the heating tank 1 reaches the set temperature threshold 104, and circulate in sequence until the warm water tank liquid level sensor 202 collects the water level signal, and the first solenoid valve 4 is closed. This method occurs when the demand for drinking water is large.

If the t time is reached, the liquid level sensor 103 under the heating tank does not collect the water level signal, and the second solenoid valve 6 is opened. If the flow meter 5 has no water flow signal, the second solenoid valve 6 is closed. At this time, the MCU opens the control output circuit. The first electromagnetic valve 4 starts the heating device 104 at the same time, closes the first electromagnetic valve 4 when the liquid level sensor 102 on the heating tank collects the water level signal, and closes the heating device 104 when the water temperature in the heating tank 1 reaches the set temperature threshold , and circulate in sequence until the water level signal is collected by the liquid level sensor 202 of the warm water tank, and the first electromagnetic valve 4 is closed. This mode occurs when there is little demand for drinking water or when no one is drinking water.

If after a period of time, when the temperature in the warm water tank 2 reaches the set temperature threshold (eg: 20° C.), the MCU controls the third solenoid valve 7 to open through the control output circuit. It should be noted that the temperature of the water initially injected into the warm water tank 2 is about 85°C.

It should be noted that when cold water is injected into the heating box 1 and heated, if no one is drinking at this time and the hot water in the heating box 1 is cooled for t time, all the water in the heating box 1 needs to be drained into warm water In the tank 2, now in order to ensure that the water in the heating tank 1 can all be discharged into the warm water tank 2, it is necessary to ensure that the volume of the heating tank 1 is less than that of the warm water tank 2.

In addition, it should be noted that when the water level of the warm water tank 2 reaches a predetermined value, the first solenoid valve 4 is in a closed state. In order to avoid this situation, when the water level signal is collected by the liquid level sensor 202 of the warm water tank and the first electromagnetic valve 4 is closed, the "full water" indicator light (yellow light) is on, prompting the user to drink warm water first. After having water to flow out in 2, because the water level of warm water tank 2 fails to reach this predetermined value, then can repeat above-mentioned operation of reheating hot water.

Similarly, in order to avoid the situation that the water in the cold water tank 3 is full and the water in the warm water tank 2 cannot be injected into the cold water tank 3, a communicating pipe can be arranged outside the cold water tank 3, and the water level of the communicating pipe can visually observe the cold water tank. 3 within the water level.
