The water storage container 121 may be a water storage tank or a water storage bin, and is used for storing water, the first control valve 123 is an electromagnetic valve and is used for controlling the on/off of the second water inlet pipeline 122, and when the first control valve 123 is in an open state, water in the first water inlet pipeline 111 can flow into the water storage container 121 through the second water inlet pipeline 122.
The cold water supply pipeline includes a cold water supply trunk 230, a first cold water supply branch 210, a second cold water supply branch 220, and a second control valve 240 disposed on the cold water supply trunk 230. The cold water main supply line 230 is used for connecting a water source, and the second control valve 240 may be a solenoid valve for controlling the on/off of the cold water main supply line 230. The first cold water supply branch 210 and the second cold water supply branch 220 are both communicated with the cold water main supply 230, the first cold water supply branch 210 is communicated with the first water inlet pipe 111, and the second cold water supply branch 220 is used for providing cold water for the shower head 700.

When the third control valve 400 is in the open state, the second control valve 240 is in the closed state, and the first control valve 123 is in the closed state, the first cold water supply branch 210, the first water inlet pipe 111, the heater, the first water outlet pipe 113, the hot water supply pipe 300, and the second cold water supply branch 220 are sequentially communicated and cooperate to form a circulation loop.
The water pump 130 is disposed in the first cold water supply branch 210, the first water inlet pipeline 111 or the second cold water supply branch 220, and the water pump 130 is located upstream of a junction point of the first water inlet pipeline 111 and the second water inlet pipeline 122.
It should be noted that the water pump 130 is located upstream of the junction of the first water inlet pipeline 111 and the second water inlet pipeline 122, which means that when the water pump 130 is started, the water in the water supply device flows through the water pump 130 and the junction of the first water inlet pipeline 111 and the second water inlet pipeline 122 in sequence.
When the third control valve 400 is in the open state and the second control valve 240 and the first control valve 123 are in the closed state, the water pump 130 is activated to circulate the water in the water supply device through the first cold water supply branch 210, the first water inlet pipe 111, the heater, the first water outlet pipe 113, the hot water supply pipe 300 and the second cold water supply branch 220. When the heater is in an on state, water in the apparatus can be heated in a circulating manner, and hot water is provided in the hot water supply line 300. When the user needs to use hot water, the hot water directly flows out of the shower head 700 to implement a 'zero cold water' function. After the water supply device realizes the "zero cold water" function, when the first control valve 123 is in the open state and the second control valve 240 and the third control valve 400 are in the closed state, the water pump 130 pumps water in the first cold water supply branch 210 and the second cold water supply branch 220 into the water storage container 121, so that hot water which is not circularly heated in the second cold water supply branch is not circulated.
Specifically, in the above water supply device, when the "zero hot water" function is activated, the third control valve 400 is opened, the second control valve 240 and the first control valve 123 are closed, the first cold water supply branch 210, the first water inlet pipe 111, the heater, the first water outlet pipe 113, the hot water supply pipe 300 and the second cold water supply branch 220 are sequentially connected and cooperate to form a circulation loop, when the water pump 130 is activated, water circulates in the circulation loop, and the heater is activated during circulation, so that the water is heated and heated after passing through the heater during the circulation. Thus, hot water can be provided in the hot water supply pipe 300, and when a user needs to use the hot water, the hot water directly flows out of the shower head 700, so as to realize a 'zero cold water' function. When the water supply device achieves the 'zero cold water' function, the heater stops heating, the first control valve 123 is opened, the second control valve 240 and the third control valve 400 are closed, at this time, the water pump 130 continues to operate, water in the first cold water supply branch 210 and the second cold water supply branch 220 flows into the water storage container 121 under the action of the water pump 130, when the second cold water supply branch 220 does not have hot water circularly heated, the water pump 130 is closed, and then the second control valve 240 is opened, so that cold water in the cold water supply main line 230 can flow into the second cold water supply branch 220. Therefore, when a user needs to use cold water, the cold water in the second cold water supply branch 220 can directly flow out, hot water which is circularly heated cannot flow out, and the user experience is improved. Therefore, in the above water supply device, after the user starts the "zero cold water" function, the shower 700 can directly flow out hot water when the user needs to use hot water, and the shower 700 can directly flow out cold water when the user needs to use cold water, so that the user experience is greatly improved.
In addition, in the above water supply device, the problem of low water pressure and small flow rate in the device can be solved by providing the water pump 130.
In one embodiment, the water pump 130 is disposed on the first water inlet pipe 111, the water storage branch further includes a second water outlet pipe 124 and a fourth control valve 125, the water storage container 121 is communicated with the first water inlet pipe 111 through the two water outlet pipes, a junction point of the second water outlet pipe 124 and the first water inlet pipe 111 is located upstream of the water pump 130, and the fourth control valve 125 is disposed on the second water outlet pipe 124. After the "zero cold water" function is activated, the water storage tank 121 stores water from the first cold water supply branch 210 and the second cold water supply branch 220, and when the user needs to use hot water, the first control valve 123 is closed, and the fourth control valve 125 is opened, so that the water in the water storage tank 121 can be pumped by the water pump 130 for use.
Further, a liquid level sensor 126 is disposed in the water storage container 121. The liquid level sensor 126 may detect whether the water storage tank 121 has water, and when the liquid level sensor 126 detects that the water storage tank 121 has water at a preset position, the fourth control valve 125 may be closed, and tap water alone may be used for supplying the water.
Specifically, the liquid level sensor 126 may be disposed at the bottom of the water storage container 121, and the fourth control valve 125 is closed when the liquid level sensor 126 detects that there is no water in the water storage container. Of course, in other embodiments, the level sensor 126 may be positioned at one-third or one-fifth of the height of the effluent receptacle.
In another embodiment, the water storage tank 121 is connected to the first cold water supply branch via two water outlet pipes, and the junction point of the second water outlet pipe 124 and the first cold water supply branch is located upstream of the water pump 130, and the fourth control valve 125 is disposed on the second water outlet pipe 124. In this embodiment, when the user needs to use hot water, the first control valve 123 is closed, and the fourth control valve 125 is opened, so that the water in the water storage container 121 can be pumped out for use.
In one embodiment, the water supply device further includes a flow sensor 140, and the flow sensor 140 can directly or indirectly detect whether the second cold water supply branch 220 has water. When the user starts the "zero cold water" function, and after the first control valve 123 is opened, the second control valve 240 and the third control valve 400 are closed, the flow sensor 140 may detect whether there is water in the second cold water supply branch 220, and if there is no water in the second cold water supply branch 220, the water pump 130 may be turned off, and the second control valve 240 may be opened, so that the cold water in the cold water supply main 230 may flow into the second cold water supply branch 220.
Optionally, the flow sensor 140 is disposed in the first water inlet pipeline 111 and upstream of the junction of the first water inlet pipeline 111 and the second water inlet pipeline 122, and when the flow sensor 140 does not detect water flow, it can indirectly detect that the second cold water supply branch 220 has no water; or the flow sensor 140 is disposed in the first cold water supply branch 210, when the flow sensor 140 detects that there is no water flowing through the first cold water supply branch 210, it can also indirectly detect that there is no water in the second cold water supply branch 220; or the flow sensor 140 is disposed on the second water inlet pipe 122, when the flow sensor 140 detects that there is no water flow in the second water inlet pipe 122 when the first control valve 123 is open, it can indirectly indicate that there is no water in the second cold water supply branch 220; or the flow sensor 140 is disposed at the second cold water supply branch 220 and is located near one end of the first cold water supply branch 210, so that when the flow sensor 140 does not detect water flowing through, it can directly detect that the second cold water supply branch 220 has no water.
