DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to FIG. 1, a drinking water fountain in accordance with the preferred embodiment of the present invention comprises a valve body 10 having a side formed with a valve chamber 11, a lower portion provided with a heating device 30 and an upper portion provided with a mixed chamber 16, a control valve 20 rotatably mounted in the valve chamber 11 of the valve body 10, a water outlet pipe 17 mounted on the valve body 10 and connected to the mixed chamber 16 of the valve body 10, a cold water inlet conduit 12 mounted in the valve body 10 and having a first end connected to a water inlet port 21 of the control valve 20 and a second end connected to a water filter 32, a cold water outlet conduit 13 mounted in the valve body 10 and having a first end connected to a first water outlet port 22 of the control valve 20 and a second end connected to the mixed chamber 16 of the valve body 10, a heating conduit 14 mounted in the valve body 10 and having a first end connected to a second water outlet port 23 of the control valve 20 and a second end connected to the heating device 30, and a hot water inlet conduit 15 mounted in the valve body 10 and having a first end connected to the heating device 30 and a second end connected to the mixed chamber 16 of the valve body 10.
When in use, referring to FIG. 2, when the control valve 20 is rotated to a first position, the filtered water from the water filter 32 flows through the cold water inlet conduit 12 and the water inlet port 21 of the control valve 20 into the control valve 20. Then, the water from the control valve 20 flows through the first water outlet port 22 of the control valve 20 and the cold water outlet conduit 13 into the mixed chamber 16 of the valve body 10. Finally, the water from the mixed chamber 16 of the valve body 10 flows into the water outlet pipe 17. Thus, the cold water flows outward from the water outlet pipe 17 for use.
Alternatively, referring to FIG. 3, when the control valve 20 is rotated to a second position, the filtered water from the water filter 32 flows through the cold water inlet conduit 12 and the water inlet port 21 of the control valve 20 into the control valve 20. Then, the water from the control valve 20 flows through the second water outlet port 23 of the control valve 20 and the heating conduit 14 into the heating device 30. Then, the heated water from the heating device 30 flows through the hot water inlet conduit 15 into the mixed chamber 16 of the valve body 10. Finally, the heated water from the mixed chamber 16 of the valve body 10 flows into the water outlet pipe 17. Thus, the hot water flows outward from the water outlet pipe 17 for use.
Alternatively, referring to FIG. 4, when the control valve 20 is rotated to a third position, the filtered water from the water filter 32 flows through the cold water inlet conduit 12 and the water inlet port 21 of the control valve 20 into the control valve 20. Then, the water from the control valve 20 partially flows through the first water outlet port 22 of the control valve 20 and the cold water outlet conduit 13 into the mixed chamber 16 of the valve body 10. At the same time, the water from the control valve 20 partially flows through the second water outlet port 23 of the control valve 20 and the heating conduit 14 into the heating device 30 to form hot water which flows through the hot water inlet conduit 15 into the mixed chamber 16 of the valve body 10. At this time, the cold water from the cold water outlet conduit 13 mixes with the hot water from the hot water inlet conduit 15 in the mixed chamber 16 of the valve body 10 to form a mixed water having a proper temperature. Finally, the mixed water from the mixed chamber 16 of the valve body 10 flows into the water outlet pipe 17. Thus, the mixed water flows outward from the water outlet pipe 17 for use.
Referring to FIG. 5, a drinking water fountain in accordance with another embodiment of the present invention further comprises a second control valve 20A to control non-drinking water. The valve body 10A has a second side formed with a second valve chamber 11A to receive the second control valve 20A. The drinking water fountain further comprises a second water outlet pipe 17A mounted on the valve body 10A, a second cold water inlet conduit 12A mounted in the valve body 10A and connected to the second water outlet pipe 17A and the second control valve 20A, a second hot water inlet conduit 13A mounted in the valve body 10A and connected to the second water outlet pipe 17A and the second control valve 20A, and a mixed water outlet conduit 14A mounted in the valve body 10A and connected to the second water outlet pipe 17A and the second control valve 20A. Thus, the second control valve 20A is used to control the non-drinking water flowing outward from the second water outlet pipe 17A, including cold water, hot water and mixed water.
Accordingly, the drinking water fountain can provide drinking water, including cold water, hot water and mixed water. In addition, the drinking water fountain can provide non-drinking water, including cold water, hot water and mixed water. Further, the control valve is used to control the drinking water flowing outward from the water outlet pipe, including cold water, hot water and mixed water, thereby facilitating a user drinking the drinking water. Further, the second control valve is used to control the non-drinking water flowing outward from the second water outlet pipe, including cold water, hot water and mixed water, thereby facilitating a user using the non-drinking water.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
