The clean water tank is connected to the cold water faucet, and the hot water tank is connected to the hot water faucet. A water purification device is also provided in the water dispenser, and the water purification device is connected to the clean water tank. The external water enters the clean water tank after being filtered by the water purification device, while the hot water tank is directly connected to the external water source. In this way, the cold water output from the water dispenser is filtered, and the hot water output is not filtered. Although the water can kill bacteria in the water after heating, the impurities in the water cannot be removed, which will affect people's health.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0018] See also Figure 1-Figure 3 The water system of the commercial water dispenser includes a water purification device 1, a water purification tank 2, a hot water tank 3, a first water pump 4, a second water pump 5, a first faucet 6 and a second faucet 7. The water inlet of the water purification device 1 is connected to a water source (tap water), the water inlet of the first water pump 4 is connected to the water outlet of the water purification device 1, and the water outlet of the first water pump 4 is connected to the water inlet of the water purification tank 2 to pump the source water filtered by the water purification device 1 into the water purification tank 2, the water inlet of the second water pump 5 is connected to the water outlet of the water purification tank 2, and the water outlet of the second water pump 5 is connected to the water inlet of the hot water tank 3 to pump the pure water in the water purification tank 2 into the hot water tank 3, the water outlet of the water purification tank 2 is connected to the first faucet 6, and the water outlet of the hot water tank 3 is connected to the second faucet 7.
[0019] It also includes a first solenoid valve 8, a second solenoid valve 9, a third solenoid valve 10, a fourth solenoid valve 11, a first three-way joint 12 and a second three-way joint 13. The clean water tank 2 includes a first water outlet, a second water outlet and a fifth water outlet. The hot water tank 3 includes a third water outlet and a fourth water outlet. The first water outlet, the first solenoid valve 8, the first three-way joint 12 and the first faucet 6 are connected in sequence, the fourth water outlet, the fourth solenoid valve 11 and the first three-way joint 12 are connected in sequence, the third water outlet, the third solenoid valve 10, the second three-way joint 13 and the second faucet 7 are connected in sequence, and the second water outlet, the second solenoid valve 9 and the second three-way joint 13 are connected in sequence; the water inlet of the second water pump 5 is connected to the fifth water outlet of the clean water tank 2.
[0020] In the above structure, when the first solenoid valve 8 is opened alone, the first faucet 6 discharges pure water (cold water); when the second solenoid valve 9 is opened alone, the second faucet 7 discharges pure water; when the third solenoid valve 10 is opened alone, the second faucet 7 discharges hot water; when the fourth solenoid valve 11 is opened alone, the first faucet 6 discharges hot water; when the first solenoid valve 8 and the fourth solenoid valve 11 are opened at the same time, the first faucet 6 discharges warm water; when the second solenoid valve 9 and the third solenoid valve 10 are opened at the same time, the second faucet 7 discharges warm water; therefore, the first faucet 6 and the second faucet 7 can both discharge pure water, hot water and warm water, which is convenient for users.
[0021] A one-way valve 14 is arranged between the first water outlet and the first solenoid valve 8, between the second water outlet and the second solenoid valve 9, between the third water outlet and the third solenoid valve 10, and between the fourth water outlet and the fourth solenoid valve 11. The one-way valve 14 can prevent water from flowing back to the clean water tank 2 or the hot water tank 3.
[0022] The clean water tank 2 and the hot water tank 3 are respectively located above the first faucet 6 and the second faucet 7. When the faucet is turned on, the water in the water tank flows to the faucet under the action of weight, realizing gravity water discharge (water storage discharge). Compared with the pressure water discharge of traditional water dispensers, the water discharge is smoother and the water discharge is in the form of a water column, so that the water discharge volume is large, the water discharge is more efficient, and splashing can be prevented during water discharge. For traditional water dispensers, when the water volume in the water tank is large, the water discharge volume is large and it is easy to splash. When the water volume in the water tank is small, the water discharge volume is small, so the water discharge is unstable.
[0023] The water purifier 1 is provided with an RO reverse osmosis filter element 15 for filtering water, which can effectively filter impurities in the water and improve the quality of the output water.
[0024] The purified water tank 2 is provided with a disinfection device 16 for disinfecting water. The disinfection device 16 is a UV lamp, which can effectively kill bacteria in the water and further improve the quality of the output water.
[0025] The hot water tank 3 is provided with a heating device 17 for heating water, and the heating device 17 is a heating pipe.
[0026] The first water pump 4 and the second water pump 5 are brushless DC water pumps.
[0027] The water dispenser includes a body 18, a first chamber 19 is arranged on the top of the body 18, a purified water tank 2 and a hot water tank 3 are arranged in the first chamber 19, a first faucet 6 and a second faucet 7 are arranged at the bottom of the first chamber 19, a second chamber 20 is arranged at the bottom of the body 18, and a water purification device 1 is arranged in the second chamber 20.
