Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a water supply device 100 according to a first embodiment of the present invention is provided. The water supply apparatus 100 includes: namely, the thermal module 10 and the waterway pipe 20.

Two ends of the second pipe 25 are respectively connected to the end of the first pipe 23 and the water inlet end of the instant heating module 10. The second pipe 25 refers to a pipe that does not need to be accessed into a branched outlet pipe. The third pipe 26 refers to a section of pipe connecting the end of the second pipe 25 to the instant thermal module 10. The second pipe 25 is provided with a differential pressure generating device 101. The water heated by the instant heating module 10 can be provided to a water supply point through the first pipe 23, and the residual water in the first pipe 23 can be guided by the pressure difference generating device 101 to be pumped to the second pipe 25 to enter the instant heating module 10 for heating. The pressure difference generating device 101 may be a PUMP (PUMP). Therefore, the influence of residual water in the pipeline on the water outlet temperature difference is avoided, and the water supply requirement of a high-precision temperature section is met; and can avoid the bacteria breeding in the pipeline by the residual water.
Referring to fig. 2-3, fig. 2 is a schematic structural diagram of a water supply device 200 according to a second embodiment of the present invention, in which a solid line with an arrow represents a water channel 20, and a dashed line represents an electrical connection wire between a component and a control circuit 30; fig. 3 is a functional schematic diagram of the electric circuit of the water supply apparatus 200 shown in fig. 2. The structural schematic diagram of the water supply device 200 provided in the second embodiment is substantially the same as the structural schematic diagram of the water supply device 100 provided in the first embodiment, and the difference is that the water supply device 200 includes an instant heating module 10 and a waterway pipeline 20, and the water supply device 200 further includes: the water-making device comprises a control circuit 30, a magnetic control switch 40, a water storage tank 50, a bidirectional conduction pipe 52, a water-making module 60, a first temperature sensor 70, a second temperature sensor 80, a flow sensor 90, a water quantity regulating valve 110, a reversing valve 120 and a one-way valve 130.
The control circuit 30 is electrically connected to the magnetic switch 40, the instant heating module 10 and the differential pressure generating device 101. The magnetic switch 40 is configured to receive a water usage signal and transmit the water usage signal to the control circuit 30, and the control circuit 30 is configured to activate the differential pressure generating device 101 to pump the residual water in the first pipe 23 to the second pipe 25 and the third pipe 26. The control circuit 30 is further configured to activate the instant heating module 10 to heat the water source to a desired temperature range, and to flow out through the purified water tap at the end of the at least one branch outlet pipe 230 for the user to use.
The water tank 50 is connected to the instant heating module 10 through the bidirectional conduction pipe 52. The water heated by the instant heating module 10 can flow to the water storage tank 50 through the bidirectional conduction pipe 52 for storage, and the water in the water storage tank 50 can flow to the instant heating module 10 through the bidirectional conduction pipe 52 for heating. The water storage tank 50 is a heat preservation water tank for storing hot water heated to a temperature range of 60-65 ℃ by the instant heating module 10. The reason for providing the water storage tank 50 is that the water supply device 100 often has a requirement for hot water of multiple temperature stages, such as making milk powder with hot water of 45 deg.C, making lemon with hot water of 65 deg.C, making coffee with hot water of 85 deg.C, and making tea with hot water of 95 deg.C.
When hot water with a temperature lower than 60-65 ℃, such as milk powder soaked in hot water with a temperature of 45 ℃ is required, water from the water source flows through the instant heating module 10, is heated by the instant heating module 10, and is directly provided to the water supply point through the first pipe 23 and the branched water outlet pipe 230 on the first pipe.
The hot water higher than 65 ℃ is provided for the water supply point by the first pipe 23 and the branched water outlet pipe 230 on the first pipe 23 after the water in the water storage tank 50 flows through the instant heating module 10 and is heated by the instant heating module 10. The hot water above 65 ℃ is generally used for drinking, so the volume of the water storage tank 50 is not too large, and can be set according to the demand of drinking water in a single high-temperature section. For example, 850 ml may be designed.
Because the power of the existing instant electric water heater is limited, generally 10A/3 kilowatt, if the electric water heater with 3 kilowatt power is used for heating water at a normal temperature section to boiled water at 95 ℃, time is consumed, and electric meters, electric wires and the like of common families are difficult to bear high-power electrical equipment.
Here, the water supply device 200 of the present invention heats the tap water to about 65 ℃ by the instant heating module 10 and stores the heated tap water in the water storage tank 50. If 95 ℃ hot water is needed, the water in the water storage tank 50 flows to the instant heating module 10 to be heated, the temperature of the water in the water storage tank 50 is about 60-65 ℃, the temperature of the 65 ℃ hot water is raised to 95 ℃, time can be saved, and the problem that household electric wires and electric meters are difficult to bear when the water in a normal temperature section, winter water and even 0 ℃ water are heated to 95 ℃ at one time is solved.
The water making module 60 is disposed on the rear end of the second pipe 25 converging with the water inlet pipe 21, the water inlet front end of the instant heating module 10, that is, the third pipe 26. The water production module 60 can isolate harmful substances and add active substances, so that the safety and the health of water quality are ensured, and the water quality and the taste are considered at the same time. The water producing module 60 is used for filtering and purifying the water source before entering the instant heating module 10 for heating, including the tap water source from the water inlet pipe 21 and the water source guided from the second pipe 25 to the third pipe 26, and configuring the activated water meeting the user's requirements, such as containing minerals and trace elements and maintaining the taste. Therefore, before the next hot water supply, the water producing module 60 is used to produce water again to remove bacteria and harmful substances in the residual water. The harmful substances in water include heavy metals, organic substances (chloroform, carbon tetrachloride), and inorganic substances (nitrite, fluoride).
The first temperature sensor 70 is disposed at a water inlet position of the instant heating module 10, and is used for sensing a temperature of water flowing into the instant heating module 10. When hot water in the low temperature section is needed, the control circuit 30 can also determine the heating power of the instant heating module 10 according to the temperature difference between the needed temperature section and the water temperature detected by the first temperature sensor 70 to heat the water source.
The second temperature sensor 80 is disposed on the first pipe 23 and the branch water outlet pipe 230, and is configured to sense a temperature of the outlet water.
The control circuit 30 can receive the temperature values sensed by the first temperature sensor 70 and the second temperature sensor 80, respectively, and calculate the difference between the two values, so as to obtain the temperature loss of the hot water on the first pipe 23 and the branch water outlet pipe 230, and compensate the temperature loss to the instant heating module 10, so that the temperature of the hot water flowing from the instant heating module 10 to the water supply point is closer to the required hot water temperature, and the water supply requirement of the precise temperature section is further met.
The flow sensor 90 and the water regulating valve 110 are sequentially arranged between the water making module 60 and the instant heating module 10. The water regulating valve 110 is an electric regulating valve, and both the water regulating valve 110 and the flow sensor 90 are electrically connected to the control circuit 30. The flow sensor 90 is configured to detect a flow value signal of water flowing into the instant heating module 10 and transmit the flow value signal to the control circuit 30, a relational expression between the water flow and the water temperature is stored in the control circuit 30, and the control circuit 30 controls the water quantity regulating valve 110 to regulate the water flow according to the received flow value signal, so as to ensure that the outlet temperature of hot water heated by the instant heating module 10 meets the water supply requirement of the high-precision temperature section.
The reversing valve 120 is disposed between the instant heating module 10 and the pressure difference generating device 101, and is used for changing the direction of the residual water in the first pipe 23 or the branch water outlet pipe 230 and flowing out through the second pipe 25. Thus, the residual water in the first pipe 23 and/or the branch water outlet pipe 230 is ensured to enter the instant heating module 10 through the water producing module 60 via the second pipe 25 and the third pipe 26.
The check valve 130 is disposed between the differential pressure generating device 101 and the water inlet front end of the water making module 60, and the check valve 130 ensures that the residual water in the second pipe 25 smoothly flows back to the third pipe 26 under the guidance of the differential pressure generating device 101, so as to prevent the formation of branch flow back flushing.
