[0019] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0020] 1. This utility model's water flow power generation device generates electricity through directional water flow and stores it in an energy storage module to power internal and external electrical devices (smart faucets, smart showerheads, smart toilets). The energy storage module provides low-voltage electricity, directly supplying power to nearby low-voltage appliances. This eliminates the need for 220V high-voltage sockets near sinks, shower rooms, and toilets, achieving water and electricity separation, reducing the cumbersome work of high-voltage wiring throughout the room, and saving on renovation costs.

[0021] 2. The energy storage module of this utility model is equipped with an energy storage battery and a power detection unit. When the power detection unit detects that the power of the energy storage battery is lower than the predetermined power value, the first control module directly or indirectly controls the circulation pump to start working, and at the same time controls the circulation electric control valve to open, so that the circulation branch realizes internal water circulation, thereby enabling the water flow power generation module to generate electricity and realize the automatic charging of the energy storage battery.

[0022] 3. This utility model provides a return pipe and an electric three-way valve between the starting positions of the first and second pipes. When the energy storage module enters the automatic charging mode, the second control module controls the electric three-way valve to work simultaneously when controlling the circulation pump to open. This makes the second connection end of the electric three-way valve, which is away from the starting end of the second pipe, and the first connection end connected, which is equivalent to cutting off the channel into the water heater. This allows the first and second pipes to be directly connected, thereby reducing the waste of hot water resources in the water heater and saving electricity.

When the energy storage module enters the automatic charging mode, the second control module will control the sterilizer to work at the same time when controlling the circulation pump to turn on, so as to achieve internal disinfection and ensure water safety.

[0040] The present invention will be further described below with reference to specific embodiments:

[0041] Example 1:

[0042] like Figure 1 As shown, a water flow charging type hot water directional circulation system is mainly used in smart bathrooms in residences, villas, and hotels, and can also be used in rooms requiring hot water, such as kitchens. It mainly includes a water heater 1, a first pipeline 2, a second pipeline 3, a circulation pump 4, a water flow power generation device 5, and a pump control device 6.

[0043] Water heater 1 has a water inlet 11 and a water outlet 12. The water inlet 11 is connected to a tap water connection pipe. A check valve 14 is installed on the tap water connection pipe 13 to prevent tap water backflow and ensure smooth water intake for water heater 1. The water outlet 12 is connected to a first pipe 2, which is a single-channel hot water pipe used to provide hot water. In this embodiment, the second pipe 3 is a single-channel cold water pipe, directly connected to the tap water connection pipe 13 upstream of the check valve 14, used to directly provide cold water; at the same time, the starting end of the second pipe 3 can be connected to the water inlet 11 through the check valve 14. A circulation pump 4 is installed on the first pipe 2 or the second pipe 3. In this embodiment, the circulation pump 4 is located at the starting end of the second pipe 3, i.e., connected to the water inlet 11 of water heater 1.

[0044] At least one circulation branch is provided between the first pipe 2 and the second pipe 3. The circulation branch has a first branch 21 connecting to the first pipe 2 and a second branch 31 connecting to the second pipe 3. At least one hot water angle valve 24 is installed at the end of the first branch 21 for supplying hot water to the user; at least one cold water angle valve 34 is installed at the end of the second branch 31 for supplying cold water to the user. The hot water angle valve 24 is generally connected to the hot water inlet of a faucet or shower head. The second branch 31 is provided with a cold water interface 311, and a cold water angle valve 34 is installed on the cold water interface 311. The cold water angle valve 34 is generally connected to the cold water inlet of a faucet or shower head. The cold water angle valve 34 and the hot water angle valve 24 form a conventional hot and cold water pipe installation structure at the installation location of a washbasin or shower head.

[0045] A circulating electric control valve 53 for controlling the opening and closing of the circulating branch and / or a circulating check valve 59 for preventing cold water backflow are installed between the first branch 21 and the second branch 31. The circulating electric control valve 53 is a normally closed electric control valve. Under normal circumstances, the circulating electric control valve 53 is in the closed state, that is, the circulating branch is in a non-circulating state. In this way, the hot water angle valve 24 can provide hot water and the cold water angle valve 34 can provide cold water without affecting each other or the water pressure of other system branches. When the circulating electric control valve 53 is opened, the circulating branch is in a circulating state. At this time, a water flow loop can be formed by sequentially passing through the water heater 1, the first pipe 2, the circulating branch, and the second pipe 3, and the water flow can achieve internal circulation.

[0046] like Figure 2 , 4 As shown, a water flow power generation device 5 capable of generating and storing electricity is installed on the circulation branch, which includes a water flow power generation module 51, an energy storage module 52, a first control module 54, a signal transmission module 55, a switch module 56, and a temperature detection module 57.

[0047] The water flow power generation module 51 has a T-shaped three-way valve body 513, a drive wheel 511 mounted on the three-way valve body 513, and a generator 512. The three-way valve body 513 has a valve inlet end connected to the first branch 21, a valve outlet end connected to the hot water angle valve 24, and a valve circulation end connected to the circulating electric control valve 53. The drive wheel 511 is rotatably mounted at the valve inlet end, and the generator 512 is mounted on the outside of the valve inlet end. The main shaft of the generator 512 extends into the valve inlet end and is fixedly connected to the drive wheel 511. When liquid is discharged from the valve outlet end (i.e., when liquid is discharged from the hot water angle valve 24) or when liquid circulates at the valve circulation end (i.e., when the circulating electric control valve 53 is open for circulation), the water flow can drive the drive wheel 511 to rotate, thereby generating electricity for the generator 512.

[0048] like Figure 2 As shown, the drive wheel 511 is a bladed impeller, including an impeller body and circumferentially distributed blades. The valve inlet end is provided with an impeller mounting cavity, a part of which coincides with the flow channel of the valve inlet end. The drive wheel 511 is located in the impeller mounting cavity, and one side of its blades is located in the flow channel of the valve inlet end. The generator 512 is fixed on the outside of the valve inlet end. When there is water flow at the valve inlet end, the blades of the drive wheel 511 rotate under the action of the water flow, thereby realizing the generation of electricity by the generator.

[0049] like Figure 3As shown, in another embodiment, the drive wheel 511 is a helical impeller, which is directly installed in the flow channel at the valve inlet end. In this case, the generator 512 is installed between the valve outlet end and the valve circulation end. The main shaft of the generator 512 extends into the inner cavity of the three-way valve body 513 and is fixedly connected to the helical impeller. When there is water flow at the valve inlet end, the helical blades of the drive wheel 511 rotate under the action of the water flow, thereby generating electricity.

[0050] The circulating electric control valve 53 is electrically connected to the energy storage module 52 and the first control module 54. The first control module 54 can control the opening and closing of the circulating electric control valve 53. When the circulating electric control valve 53 is open, the water flow circuit is open; when the electric control valve 53 is closed, the water flow circuit is closed.

[0051] The energy storage module 52 is used to store the electrical energy generated by the generator 512, and can also supply power to the circulating electric control valve 53, the first control module 54, the signal transmission module 55, the switch module 56, the temperature detection module 57, and the external electrical equipment 58. The energy storage module 52 has a wiring port for supplying power to the external electrical equipment 58, and the wiring port can be connected to the external electrical equipment 58, including low-voltage electrical appliances such as lighting, smart faucets, smart showers, and smart toilets.

[0052] The water flow power generation device 5 in this embodiment can generate electricity through directional water flow and store it through the energy storage module 52 for use by internal and external electrical devices. The energy storage module 52 provides low-voltage electricity, directly powering nearby low-voltage appliances. This eliminates the need for 220V high-voltage sockets near sinks, shower rooms, toilets, etc., thus achieving water and electricity separation, reducing the cumbersome wiring process throughout the room, and saving on renovation costs. Furthermore, even if the energy storage module 52 or the corresponding connected external electrical device 58 leaks electricity, the low-voltage electricity poses a relatively low risk to human health and will not endanger life, ensuring electrical safety in the bathroom.

[0053] In frequently used bathrooms or kitchens, each flow of hot water drives the drive wheel 511 to rotate, causing the generator 512 to generate electricity, thus passively charging the energy storage module (i.e., in passive charging mode). Under these conditions, the energy storage module 52's power is generally sufficient to meet the normal needs of the electrical equipment. However, for circulation branches that have not been used for a long time, the power of the energy storage module 52 on that branch will decrease and it will be unable to provide power to the electrical equipment, thus affecting the normal use of the equipment.

[0054] Therefore, the energy storage module 52 needs to have an automatic charging mode. The energy storage module 52 includes an energy storage battery and a power detection unit. The power detection unit can detect the battery's power level in real time or periodically and feed it back to the first control module 54. When the power detection unit detects that the battery's power level is lower than a predetermined value, the first control module 54 directly or indirectly controls the circulation pump 4 to start working, and simultaneously controls the circulation electric control valve 53 to open, enabling internal water circulation in this circulation branch, thereby allowing the water-powered generator module 51 to generate electricity and achieving automatic charging of the energy storage battery. When the power detection unit detects that the battery's power level is higher than a healthy value, the first control module 54 directly or indirectly controls the circulation pump 4 to shut down, and simultaneously controls the circulation electric control valve 53 to close, stopping the water flow and ending the charging process of the energy storage module 52.

[0055] Generally, since the water flow power generation device 5 is installed near the water-using equipment in the room, while the circulation pump is installed on the equipment platform or in the equipment room outside the room, there is a certain distance between the two. To reduce wiring, the first control module 54 in this embodiment indirectly operates the circulation pump 4. Specifically, the water flow power generation device 5 also includes a signal transmission module 55 connected to the first control module 54. The signal transmission module 55 is a wireless signal transmission module, specifically a cellular data transmission module, a radio frequency (RF) transmission module, a Bluetooth transmission module, a Wi-Fi transmission module, or a Zigbee transmission module. The energy storage module 52, the first control module 54, and the signal transmission module 55 are housed in the first control box. One end of the switch module 56 and the temperature detection module 57 are mounted on the first control box, thus forming an intelligent energy storage wireless transmission controller. The intelligent energy storage wireless transmission controller is equipped with a power supply connector for external electrical equipment. Preferably, the intelligent energy storage wireless transmission controller is placed near water-using equipment such as faucets and shower heads, for example, inside the storage cabinet of a washbasin or in the equipment space of a wall.

[0056] like Figure 5 As shown, the circulating pump 4 is connected to a pump control device 6. The pump control device 6 includes a second control box, a second control module 61 for controlling the operation of the circulating pump 4, a signal receiving module 62 connected to the second control module 61, and a power supply 63. The second control box contains the second control module 61 and the signal receiving module 62, and is connected to the power supply 63 via a power cable, thus forming an intelligent wireless receiver controller. The signal receiving module 62 is a wireless signal receiving module, specifically a cellular data receiving module, a radio frequency (RF) receiving module, a Bluetooth receiving module, a Wi-Fi receiving module, or a Zigbee receiving module. When the signal receiving module 62 receives a signal from the signal transmitting module 55, it feeds it back to the second control module 61, thereby controlling the operation of the circulating pump 4.

[0057] In this embodiment, the power supply 63 is AC mains power, which supplies power to the pump control device 6 and the circulation pump 4. Preferably, the water heater 1, the pump control device 6, and the circulation pump 4 are arranged on the equipment balcony outside the bathroom or kitchen, thereby reducing the amount of high-voltage wiring in the bathroom or kitchen and also reducing the noise impact of the circulation pump 4.

[0058] In another embodiment, the energy storage module 52 is also provided with a power display unit. When the energy storage module 52 displays a low power level, the user or maintenance personnel can manually turn on the circulation pump 4 and the circulation electric control valve 53 to realize the water flow circulation of the circulation branch, thereby charging the energy storage battery of the energy storage module 52.

[0059] In addition, after a period of non-use, the water temperature will gradually drop because the water in the first branch 21 and the first pipe 2 does not flow. At this time, when the user turns on the water supply equipment, he / she needs to drain some of the cold water before hot water can come out. This is not a user-friendly experience for high-end villas or hotels.

[0060] Therefore, this embodiment sets up a preheating mode for the circulating branch. The first control module 54 is connected to a switch module 56 and a temperature detection module 57 located near the hot water interface 211. The switch module 56 includes one or more of infrared sensors, radar, laser sensors, and human body sensors, and is located at the user's location, such as near the door, to detect whether the user is in the room. When the user is detected in the room, the switch module 56 sends a command to the first control module 54. The first control module 54 reads the water temperature from the temperature detection module 5 in real time. The temperature detection module 57 is preferentially a temperature probe. When the water temperature detected by the temperature detection module 57 is lower than the set water temperature value, the first control module 54 sends a signal through the signal transmission module 55 to drive the circulating pump 4 and to control the opening of the circulating electric control valve 53, so that the circulating branch can circulate hot water internally, thereby bringing the water temperature of the first branch 21 and the corresponding first pipe 2 to the predetermined temperature. In this way, when the user turns on the faucet, shower, or other water-using equipment, hot water can be obtained immediately, improving the user experience. At this time, the energy storage module also enters the charging mode.

[0061] Switch module 56 can also be a mechanical switch.

[0062] Example 2:

[0063] This embodiment adds a return pipeline 7 and an electric three-way valve 8 to the existing embodiment 1.

[0064] like Figure 6As shown, a return pipe 7 and an electric three-way valve 8 are provided between the starting positions of the first pipe 2 and the second pipe 3. The electric three-way valve 8 has a first connection end connected to the return pipe 7 and two second connection ends connected to the second pipe 3. The return pipe 7 is connected to the first connection end of the electric three-way valve 8 and the starting position of the first pipe 2 near the water outlet hole 12 of the water heater.

[0065] The electric three-way valve 8 is controlled by the second control module 61. Under normal circumstances, the two second connection terminals of the electric three-way valve 8 are in the normally open state, which can realize cold water inlet or hot water preheating circulation.

[0066] When the energy storage module 52 enters the automatic charging mode, as in the scheme of Embodiment 1, the water heater 1, the first pipe 2, the circulation branch, and the second pipe 3 form a water flow loop. Since the water outlet device is not working, including the water heater 1 in the water flow loop would result in additional waste of hot water. In order to achieve energy saving, when the energy storage module 52 enters the automatic charging mode, the second control module 61 of this embodiment controls the electric three-way valve 8 to work simultaneously when controlling the circulation pump 4 to open. This makes the second connection end of the electric three-way valve 8, which is away from the starting end of the second pipe 3, connected to the first connection end, which is equivalent to cutting off the channel into the water heater 1. This allows the first pipe 2 and the second pipe 3 to be directly connected, so that the water in the first pipe 2 and the second pipe 3 can circulate without consumption, thereby reducing the waste of hot water resources in the water heater and saving electricity.

[0067] Example 3:

[0068] like Figure 6 As shown, in this embodiment, based on embodiment two, a sterilizer 9 for connecting the second control module 61 is provided on the return pipe 7. The sterilizer 9 is preferably an ultraviolet sterilizer, which is used to disinfect the water flow inside the system.

[0069] When the energy storage module 52 enters the automatic charging mode, the second control module 61 will simultaneously control the ultraviolet sterilizer to work while controlling the circulation pump 4 to turn on, thereby achieving internal disinfection and ensuring water safety.

[0070] In another embodiment, the sterilizer 9 may also be located at the beginning of the first pipe 2 or the second pipe 3.

[0071] Example 4:

[0072] Based on Examples 1, 2, and 3, a constant temperature water outlet device is installed on the circulation branch.

[0073] like Figure 6 , 7As shown, the constant temperature water outlet device includes a cold water outlet pipe 32, a cold water control valve 33 for controlling the amount of cold water, a hot water outlet pipe 22, and a hot water control valve 23 for controlling the amount of hot water.

[0074] A hot water outlet pipe 22 is installed on the hot water interface 211 of the first branch 21, and a hot water control valve 23 is installed on the hot water outlet pipe 22; a cold water outlet pipe 32 is installed on the cold water interface 311 of the second branch 31, and a cold water control valve 33 is installed on the cold water outlet pipe 32. The cold water outlet pipe 32 and the hot water outlet pipe 22 converge to form a constant temperature water installation port 25. The drive unit of the cold water control valve 33 and the hot water control valve 23 is a servo motor, which is electrically connected to the energy storage module 52.

[0075] The constant temperature water outlet device in this embodiment also includes a constant temperature control module that controls the cold water control valve 33 and the hot water control valve 23. A temperature detection module 57 is provided at the constant temperature water outlet 25. The constant temperature control module quickly adjusts the size of the cold water control valve 33 and the hot water control valve 23 by sensing the outlet water temperature through the temperature detection module 57, that is, adjusts the cold water flow of the cold water outlet pipe 32 and the hot water flow of the hot water outlet pipe 22, thereby precisely controlling the temperature of the constant temperature water outlet 25 and realizing constant temperature water outlet.

[0076] The constant temperature control module in this implementation can be a separate control module or it can be directly integrated into the first control module 54.

[0077] Example 5:

[0078] This embodiment is basically the same as the schemes of embodiments one to four. The difference is that the second pipeline 3 is a hot water return pipe. The starting section of the hot water return pipe is set between the inlet check valve 14 and the water heater inlet hole 11 of the water heater 1, and is mainly used for the hot water return of the first pipeline 2.

[0079] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
