Or the cold water in the water storage tank is burned to be more than 92 ℃, then tap water is utilized to be injected into the bottom of the water storage tank through the heat exchanger, and the boiled water at the upper part is output by heat exchange. Different crowds or different scenes have different requirements on water temperature, and the functions of the water supply system in the existing water dispenser are single, the function of providing ice water is lacked, and diversified water supply requirements are difficult to meet.
In order to solve the above problems, as shown in fig. 1, the present embodiment provides a water supply system, which includes a water storage tank 1, a heat exchanger 2, an ice container 5, a normal temperature pipeline 6 and a heating tank 7, wherein at least a heating pipeline 3 and a heat exchange pipeline 4 are connected in parallel between the water storage tank 1 and the heat exchanger 2. The water storage tank 1 is communicated with the normal temperature pipeline 6, the heating pipeline 3, the heat exchange pipeline 4 and the normal temperature pipeline 6 can be independently opened and closed, and the normal temperature pipeline 6 is not opened simultaneously with the heating pipeline 3 and the heat exchange pipeline 4; the ice bladder 5 is selectively opened or closed and is disposed in the normal temperature line 6. The heating tank 7 is arranged in the heating pipeline 3 to boil the water flowing in from the water storage tank 1; the boiled water in the heating tank 7 directly flows out or flows out after heat exchange and temperature reduction with the water in the heat exchange pipeline 4 in the heat exchanger 2.

When the heating pipeline 3 is opened, the heat exchange pipeline 4 and the normal temperature pipeline 6 are closed, the heating tank 7 heats the water flowing in from the water storage tank 1, and the boiled water flows out through the heat exchange pipeline 4 in a direct current manner. When the heating pipeline 3 and the heat exchange pipeline 4 are opened, the normal temperature pipeline 6 is closed, the heating tank 7 heats the water flowing into the water storage tank 1, and the boiled water is changed into warm boiled water to flow out after heat exchange and temperature reduction of the boiled water and the water in the heat exchange pipeline 4 through the heat exchanger 2. The water supply system can provide drinking water with different temperatures such as warm boiled water, ice water, warm water and the like, thereby meeting the requirement of diversified drinking water.

When the second switch valve 9 and the ice container 5 are both opened, water in the water storage tank 1 flows into the ice container 5 through the normal-temperature pipeline 6, ice water is formed through cooling of the ice container 5, and the ice water flows out of the output pipeline 13 through the hot water flow passage of the heat exchanger 2. When the second switching valve 9 is opened and the ice container 5 is closed, water in the water storage tank 1 flows into the hot water flow passage of the heat exchanger 2 through the normal temperature pipeline 6, and the hot water flows out of the output pipeline 13.

The first pump body 10 is opened and the second pump body 11 is kept closed, and the boiled water flows into the hot water flow passage of the heat exchanger 2 through the heating pipe 3 and flows out of the boiled water from the output pipe 13. In the above process, if the second pump body 11 is opened, water in the water storage tank 1 flows into the cold water channel of the heat exchanger 2 through the heat exchange pipeline 4, and exchanges heat with the hot water channel through the cold water channel of the heat exchanger 2 to cool, so that the boiled water in the hot water channel is cooled to a set temperature, and warm boiled water flows out from the output pipeline 13, namely, is cooled and boiled.
