Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 2, a water supply system 10 according to an embodiment of the present invention at least ensures stability of a water supply process and reduces or prevents a false start of hot water when cold water is used.

Referring to fig. 1 and 3, in an embodiment, a water supply system 10 includes a water heater 100 and a communication assembly 200, wherein a hot water opening 110 and a cold water opening 120 are formed on the water heater 100. The communication assembly 200 includes a first conduit 210, a second conduit 220, a communication conduit 230, a one-way valve 240, and a flow regulating valve 250. One end of the first pipe 210 is a first water inlet end 212, and the other end is a first water outlet end 214; one end of the communication pipeline 230 is communicated between the first water inlet end 212 and the first water outlet end 214 of the first pipeline 210, and the other end of the communication pipeline 230 is communicated to the second pipeline 220; the check valve 240 is disposed in the communication pipe 230, and a flow direction of the check valve 240 is a direction from the second pipe 220 to the first pipe 210; the flow regulating valve 250 is disposed in the first pipe 210, and the flow regulating valve 250 is used for regulating the flow in the first pipe 210. The second pipe 220 is connected to the hot water port 110 of the water heater 100.

When the water supply system 10 and the communication assembly 200 are used, the second pipe 220 is connected to the hot water port 110 of the water heater 100, and hot water is circulated through the water heater 100. After the cold water can enter from the first water inlet end 212 of the first pipe 210, the cold water flows out from the first water outlet end 214 of the first pipe 210. Since one end of the communication pipe 230 is communicated between the first water inlet end 212 and the first water outlet end 214 of the first pipe 210, the other end of the communication pipe 230 is communicated to the second pipe 220, and the check valve 240 is disposed in the communication pipe 230.

Since the check valve 240 needs to be opened under a certain pressure, the flow direction of the check valve 240 is the direction from the second pipeline 220 to the first pipeline 210, so as to communicate the first pipeline 210 with the second pipeline 220. While the cracking pressure of different check valves 240 may be different, while the cracking pressure value of a single check valve 240 is generally fixed and non-adjustable. And the installation position of the water supply system 10 is different, the water pressure of the cold water flowing into the first pipe 210 may also be different, so that when the supercooled water flows into the first pipe 210, negative pressure with different pressure values is formed at one side of the check valve 240 facing the first pipe 210, if the negative pressure is greater than the opening pressure of the check valve 240, the check valve 240 is opened by mistake, and the water heater 100 connected to the second pipe 220 is started by mistake.

The water in the first pipe 210 is further sucked into the water heater 100 from the cold water inlet 120 by the water heater 100 to be heated. And then through circulation heating for be hot water in the second pipeline 220, when the user used water equipment 300, can directly flow out hot water in the second pipeline 220, need avoid discharging the remaining cold water in the second pipeline 220 earlier when needing to use hot water.
