[0002] As people become more aware of drinking water safety, large commercial water purifiers are being installed in many crowded places such as airports, high-speed rail stations, and companies. While this brings convenience, it also presents some problems. Due to the large number of users, water purifiers must be equipped with high-power heating and large heating water tanks to meet the demand. However, water purifiers are rarely used late at night.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0040] like Figure 1-2As shown in the embodiment of this specification, a water purifier 1 is provided. The water purifier 1 includes a heating water tank 2, a first pipeline 3, a heat dissipation box 4, and an electrical energy storage device 5 arranged sequentially in a vertical direction. One end of the first pipeline 3 is fixedly connected to the bottom of the heating water tank 2, and the other end is fixedly connected to the top of the heat dissipation box 4. A water valve 6 is provided on the side of the first pipeline 3 near the heating water tank 2. The water purifier 1 also includes a controller. The water valve 6 is electrically connected to the controller. Water in the heating water tank 2 flows into the heat dissipation box 4 when the water valve 6 is open.

[0041] The heat dissipation box 4 is equipped with a first temperature sensor 7; the controller is electrically connected to the first temperature sensor 7; the energy storage device 5 is detachably connected to the heat dissipation box 4 on the side near the bottom of the heat dissipation box 4; the outer surface of the heat dissipation box 4, except for the bottom, is equipped with an energy conversion device 8; the energy conversion device 8 is detachably connected to the heat dissipation box 4; the energy conversion device 8 is used to convert the heat energy carried by the water in the heat dissipation box 4 into electrical energy and store it in the energy storage device 5 when the water temperature value detected by the first temperature sensor 7 reaches a preset temperature value.

[0042] In some embodiments, the heating water tank 2 is located at the top of the water purifier 1, and the heat dissipation box 4 is located at the bottom of the water purifier 1. Since metal material can improve heat dissipation efficiency, the heat dissipation box 4 can be made of stainless steel. The first pipe 3 can be the heat dissipation box inlet pipe, with one end fixedly connected to the heating water tank 2 and the other end fixedly connected to the heat dissipation box 4. A water valve 6 is provided on the side of the first pipe 3 near the heating water tank 2; this valve can be a hot water valve. When the water valve 6 is open, water in the heating water tank 2 can flow into the heat dissipation box 4 through the first pipe 3. The power conversion device 8 can be a thermoelectric generator, and the power storage device 5 can be electrical energy. The energy storage device 5 is detachably connected to the heat sink 4 on one side near the bottom. Therefore, thermoelectric generators (i.e., energy conversion devices 8) can be attached to all five sides of the heat sink 4 except the bottom, allowing for detachable connection. To enhance usability, the heat sink 4 uses wiring harness terminals to connect the energy storage device 5 and the energy conversion device 8. Since the energy storage device 5 relies on temperature difference for energy conversion, it is attached to the outside of the heat sink 4 to maximize energy conversion efficiency. The thermoelectric generator, also known as a thermocouple generator, is based on the Seebeck effect. The electromotive force (EMF), also known as the first thermoelectric effect, is generated when two conductors of different materials are connected to form a closed circuit with a temperature difference between their ends, thus producing an electric current. In practical use, when water from the heating tank 2 flows into the heat exchanger 4, the side of the power conversion device 8 closest to the heat exchanger 4 has a higher temperature due to the presence of hot water. The side of the power conversion device 8 away from the heat exchanger 4 is air, which has a lower temperature. The power conversion device 8 generates electricity by utilizing the temperature difference between the two sides, converting the heat energy carried by the water in the heat exchanger 4 into electrical energy. The greater the temperature difference between the two sides of the power conversion device 8, the greater the EMF generated, and the greater the power generation, i.e., the more electrical energy is converted. To reduce the loss of electrical energy in the conductors and to increase the temperature difference, the heat exchanger 4 is placed at the bottom of the water purifier 1, away from the heat radiation near the heating tank 2, maximizing the temperature difference and thus improving the power generation efficiency of the power conversion device 8.A first temperature sensor 7 is installed inside the heat dissipation box 4 and is electrically connected to the controller. The first temperature sensor 7 is used to detect the water temperature in the heat dissipation box 4. The preset temperature value can be 40℃. When the water in the water tank 2 flows into the heat dissipation box 4, the power conversion device 8 uses the temperature difference on both sides of the power conversion device 8 to convert the heat energy carried by the water in the heat dissipation box 4 into electrical energy. That is, the two ends of the thermoelectric generator output a certain voltage, which can also be regarded as a voltage source. The positive and negative poles of the five thermoelectric generators on the outside of the heat dissipation box 4 are connected in series to form a series voltage source. This series voltage source is connected to the power storage device 5, that is, the power storage box. The energy storage box can be considered to consist of a voltage regulator circuit, a set of rechargeable batteries, and a control switch. The output voltage of the battery can be 5V. When the output voltage of the series voltage source is greater than 5V, the control switch is turned on, and the thermoelectric generator charges the rechargeable battery. When the output voltage of the series voltage source is less than 5V, the control switch is turned off, and the thermoelectric generator stops charging the rechargeable battery, thus completing the entire charging process. That is, the energy conversion device 8 stores the converted energy in the battery in the energy storage device 5. When the water temperature in the heat sink 4 is less than 40℃, the water in the heat sink 4 no longer carries heat energy, and the water in the heat sink 4 is drawn into the heating water tank 2.

[0043] In other embodiments, the preset temperature value can be set according to actual conditions.

[0044] The water purifier 1 further includes a first partition 9, a second partition 10, and a third partition 11; the first partition 9, the second partition 10, and the third partition 11 are all arranged vertically inside the heat dissipation box 4; the second partition 10 is disposed between the first partition 9 and the third partition 11; the side of the first partition 9 away from the second partition 10 is the first side 12 of the heat dissipation box 4; the side of the third partition 11 away from the second partition 10 is the second side 13 of the heat dissipation box 4.

[0045] In some embodiments, such as Figure 2As shown, the first partition 9, the second partition 10, and the third partition 11 can all be stainless steel baffles. The first partition 9, the second partition 10, and the third partition 11 are all vertically arranged inside the heat dissipation box 4, but they are arranged sequentially in the horizontal direction. The second partition 10 is located between the first partition 9 and the third partition 11. The side of the first partition 9 furthest from the second partition 10 is the first side 12 of the heat dissipation box 4, and the side of the third partition 11 furthest from the second partition 10 is the second side 13 of the heat dissipation box 4. By setting three partitions inside the heat dissipation box, the sealed heat dissipation box is divided into four interconnected cavities. Water from the heating tank flows into the heat dissipation box and then flows along the cavities formed by the partitions. This helps the heat dissipation box simultaneously allow hot water to flow in and cold water to flow out, improving the power generation efficiency of the power conversion device, reducing power consumption, and saving energy.

[0046] The height values ​​of the first partition 9, the second partition 10, and the third partition 11 are all less than the height value of the heat sink 4; the top of the first partition 9 is fixedly connected to the top of the heat sink 4; the bottom of the second partition 10 is fixedly connected to the bottom of the heat sink 4; and the top of the third partition 11 is fixedly connected to the top of the heat sink 4.

[0047] In some embodiments, such as Figure 2 As shown, the heights of the first partition 9, the second partition 10, and the third partition 11 are all less than the height of the heat exchange box 4, and these three partitions can have the same height. The top of the first partition 9 is fixedly connected to the top of the heat exchange box 4, the bottom of the second partition 10 is fixedly connected to the bottom of the heat exchange box 4, and the top of the third partition 11 is fixedly connected to the top of the heat exchange box 4. By setting three partitions whose heights are all less than the height of the heat exchange box, the heat exchange box is divided into four interconnected chambers. The water flow direction in the heat exchange box is clear, and the water in the heat exchange box can flow in the set direction, which helps to remove the cold water in the heat exchange box in a timely manner. This not only improves the power generation efficiency of the power conversion device and saves energy, but also ensures that the water volume in the heat exchange box is always within a safe range, thus extending the service life of the water purifier.

[0048] In other embodiments, the height values ​​of the first partition 9, the second partition 10, and the third partition 11 can be set according to actual conditions.

[0049] The water purifier 1 further includes a fourth partition 14; the fourth partition 14 is vertically disposed within the heating water tank 2; the height of the fourth partition 14 is less than the height of the heating water tank 2; the bottom of the fourth partition 14 is fixedly connected to the bottom of the heating water tank 2; the heating water tank 2 is divided into a first cavity 15 and a second cavity 16 by the fourth partition 14; a first water outlet is provided at the bottom of the first cavity 15; a second temperature sensor 17 is disposed within the first cavity 15; the second temperature sensor 17 is electrically connected to the controller; the second temperature sensor 17 is used to detect the water temperature in the heating water tank 2.

[0050] In some embodiments, such as Figure 1 As shown, the fourth partition 14 can be a stainless steel baffle, and the height of the fourth partition 14 can be less than the height of the heating water tank 2. The bottom of the fourth partition 14 is fixedly connected to the bottom of the heating water tank 2. A water level sensor or water level probe can be installed inside the heating water tank 2. The water level detected by the probe can be within a certain range. The height of the fourth partition 14 can be related to the water level detected by the water level sensor. The height of the fourth partition 14 is less than or equal to the highest water level detected by the water level sensor, so as to separate the hot water in the first chamber 15 of the heating water tank 2 from the cold water in the second chamber 16. The heating water tank 2 is divided into the first chamber 15 and the second chamber 16 arranged side by side by the fourth partition 14. The volume of the first chamber 15 can be greater than the volume of the second chamber 16. A first water outlet can be provided at the bottom of the first chamber 15. A second temperature sensor 17 can be installed inside the first chamber 15. The second temperature sensor 17 is electrically connected to the controller and is used to detect the water temperature in the heating water tank 2. By setting a fourth partition to divide the heating water tank into a first chamber and a second chamber, the cold water that has been used up is effectively prevented from mixing into the hot water on the left side, and the hot water in the heating water tank is discharged, which improves the power generation efficiency of the power conversion device and maximizes the use of the thermal energy of the hot water in the heating water tank, thus achieving energy saving.

[0051] The first partition 9 and the first side 12 form a third cavity 18; the top of the third cavity 18 is provided with a first water inlet; one end of the first pipe 3 is fixedly connected to the first water outlet, and the other end is fixedly connected to the first water inlet; the third partition 11 and the second side 13 form a fourth cavity 19; the third cavity 18 and the fourth cavity 19 are connected.

[0052] The top of the fourth cavity 19 is provided with a second water outlet; the top of the second cavity 16 is provided with a second water inlet; the water purifier 1 also includes a second pipe 20; one end of the second pipe 20 is fixedly connected to the second water outlet, and the other end is fixedly connected to the second water inlet.

[0053] In some embodiments, such as Figure 2 As shown, a third cavity 18 is formed between the first partition 9 and the first side 12. A first water inlet is provided at the top of the third cavity 18. One end of the first pipe 3 is fixedly connected to the first water outlet, and the other end of the first pipe 3 is fixedly connected to the first water inlet. A fourth cavity 19 is formed between the third partition 11 and the second side 13. The third cavity 18 and the fourth cavity 19 are connected. Figure 2 The dotted line indicates the flow direction of water from the heating water tank 2 into the heat exchanger 4. In reality, the heat exchanger 4 is divided into four interconnected chambers by the first partition 9, the second partition 10, and the third partition 11, allowing water flow within the heat exchanger 4. Simultaneously, a second water outlet is located at the top of the fourth chamber 19, and a second water inlet is located at the top of the second chamber 16. The water purifier 1 also includes a second pipe 20, which is the heat exchanger outlet pipe. One end of the second pipe 20 is fixedly connected to the second water outlet, and the other end is fixedly connected to the second water inlet. The second pipe 20 allows the used cold water in the heat exchanger 4 to flow into the second chamber 16 of the heating water tank 2. By setting multiple chambers within the heat exchanger, it helps to quickly drain the used cold water from the heat exchanger, preventing it from mixing with the hot water inside. At the same time, the second pipe allows the cold water to flow out of the heat exchanger, keeping the water volume within the heat exchanger within a safe range and extending the service life of the water purifier.

[0054] The second pipeline 20 is equipped with a pump body 21 on the side near the heating water tank 2; the pump body 21 is electrically connected to the controller; the pump body 21 is used to control the flow of water from the heat sink 4 into the second cavity 16.

[0055] In some embodiments, the pump body 21 can be a DC pump. The pump body 21 is installed on the side of the second pipeline 20 near the heating water tank 2, and the pump body 21 is electrically connected to the controller. When the pump body 21 is turned on, water in the heat exchanger 4 flows into the second cavity 16 of the heating water tank 2 through the second pipeline 20. By installing the pump body on the second pipeline, the used cold water in the heat exchanger can be circulated in a timely manner, avoiding the mixing of hot and cold water in the heat exchanger, thereby improving the power generation efficiency of the power conversion device and helping the water purifier to enter standby mode in a timely manner when no one is using it, thus achieving energy saving.

[0056] The water purifier 1 also includes a heating plate 22; the heating plate 22 is disposed in the first cavity 15; the heating plate 22 is electrically connected to the controller; the heating plate 22 is used to heat the water in the heating water tank 2.

[0057] In some embodiments, a heating plate 22 is further provided inside the first cavity 15, and the heating plate 22 is electrically connected to the controller. The heating plate 22 is used to heat the water in the water tank 2 when the user uses the water purifier 1, so that the water can be used by the user. By providing a heating plate inside the water tank, the heating efficiency of the water purifier is improved so that it can be heated when needed.

[0058] In the embodiments of this specification, based on the water purifier provided above, this specification also provides a method for storing electrical energy in a water purifier. To better achieve the control process, specific embodiments of the method for storing electrical energy in a water purifier according to this invention are described below. Figure 3 This is a flowchart illustrating a method for storing electrical energy in a water purifier according to an embodiment of the present invention. This specification provides the operational steps of the method described in the embodiments or flowcharts, but based on conventional or non-inventive methods, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server product execution, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown in the flowcharts... Figure 3 As shown, the method may include:

[0059] S301: In response to the energy storage command, obtain the current working time period corresponding to the water purifier and the current idle time period corresponding to the water purifier.

[0060] In the embodiments of this specification, since the water purifier is not used at night in most cases, the user can set the water purifier to enter the energy-saving mode at night, so that the power conversion device inside the water purifier converts the heat energy carried by the hot water in the heating tank into electrical energy; thereby, the water purifier will receive the power storage instruction, and then obtain the current working time and the current idle time of the water purifier.

[0061] S303: If the current working period is within a preset period and the current idle time is longer than the preset idle time, control the water valve to open and obtain the first opening time corresponding to the water valve; so that the water in the heating water tank flows into the heat dissipation box through the first pipe.

[0062] In the embodiments of this specification, the preset time period can be after 0:00 AM, and the preset idle time can be 1 hour. If the current working time of the water purifier is after 0:00 AM, and the current idle time is greater than 1 hour, that is, no one has used it for more than 1 hour, the energy-saving mode is activated. When the water temperature in the first chamber of the heating water tank reaches the preset temperature value, the water valve is controlled to open so that the water in the heating water tank flows into the heat dissipation box through the first pipe. The first opening time corresponding to the water valve is obtained to achieve precise control of the amount of hot water flowing into the heat dissipation box and avoid damage to the heat dissipation box due to excessive water.

[0063] In this embodiment of the specification, the step of controlling the water valve to open and obtaining the first opening duration corresponding to the water valve if the current working period is within a preset period and the current idle period is longer than the preset idle period includes:

[0064] If the current working period is within the preset period and the current idle time is longer than the preset idle time, obtain the second temperature value collected by the second temperature sensor in the heating water tank;

[0065] In the embodiments of this specification, if the current working time of the water purifier is after 0:00 AM and no one uses it for more than 1 hour, the second temperature value collected by the second temperature sensor in the heating water tank is obtained. Since the second temperature sensor is set in the heating water tank, the second temperature value is the water temperature value in the heating water tank.

[0066] If the second temperature value is greater than the preset temperature value, control the water valve to open and obtain the first opening duration corresponding to the water valve.

[0067] In this embodiment, the preset temperature value can be 40℃. When the second temperature value is greater than 40℃, the water valve is opened, allowing hot water in the first chamber to flow into the heat exchanger through the first pipe. The first opening duration of the water valve is also obtained to control the water inflow into the heat exchanger. By acquiring the second temperature value collected by the second temperature sensor in the heating water tank, hot water is promptly supplied to the heat exchanger when it is present in the heating water tank, maximizing the utilization of the heat energy carried by the hot water in the heating water tank and achieving energy saving. At the same time, controlling the opening duration of the water valve helps to keep the water volume in the heat exchanger within a safe range, extending the service life of the water purifier.

[0068] S305: If the first opening duration is greater than or equal to the preset opening duration, control the water valve to close and obtain the first temperature value collected by the first temperature sensor in the heat sink.

[0069] In the embodiments of this specification, the preset opening time can be 30s. When the opening time of the water valve reaches 30s, that is, when the first opening time is greater than or equal to 30s, the heat sink is filled with hot water. The water valve is then closed, the water supply to the heat sink stops, and the first temperature value collected by the first temperature sensor in the heat sink is obtained. The first temperature value represents the water temperature value in the heat sink.

[0070] S307: If the first temperature value is greater than or equal to the preset temperature value, send an energy conversion command to the energy conversion device outside the heat sink; so that the energy conversion device converts the heat energy carried by the water in the heat sink into electrical energy based on the energy conversion command, and transmits the electrical energy to the energy storage device located at the bottom of the heat sink; so that the energy storage device receives and stores the electrical energy.

[0071] In this embodiment, when the first temperature value is greater than 40°C, a power conversion command is sent to the power conversion device outside the heat sink, causing the power conversion device to convert the heat energy carried by the water in the heat sink into electrical energy based on the power conversion command. In fact, after the water in the heating tank flows into the heat sink, the power conversion device, i.e., the thermoelectric generator, begins to generate electricity using the temperature difference between its two sides. Since thermoelectric generators are attached to all five outer surfaces of the heat sink, the positive and negative terminals of the five thermoelectric generators are connected in series to form a series voltage source. The voltage source is connected to the energy storage device, i.e., the energy storage box. The energy storage box consists of a voltage regulator circuit, a set of rechargeable batteries, and a control switch. Assuming the rechargeable battery output voltage is 5V, when the output voltage of the series voltage source is greater than 5V, the control switch is turned on, and the thermoelectric generator charges the rechargeable battery; that is, the energy conversion device transfers energy to the energy storage device. When the output voltage of the series voltage source is less than 5V, the control switch is turned off, the thermoelectric generator stops charging the rechargeable battery, and the entire charging process ends, with energy stored in the energy storage device. In actual use, the water purifier can be powered by the batteries in the energy storage device, entering standby mode. When the voltage of the energy storage device is low, it can switch to mains power without affecting the operation of the water purifier. By converting the heat energy carried by the hot water in the heat exchanger into electrical energy through an external power conversion device, and storing the generated electrical energy in an energy storage device, the water purifier can enter standby mode when no one is using it, based on the electrical energy stored in the energy storage device. This reduces the power consumption of the water purifier, achieves energy saving, and improves the intelligence level of the water purifier.

[0072] In the embodiments of this specification, after sending an energy conversion command to the energy conversion device outside the heat sink if the first temperature value is greater than or equal to a preset temperature value, as follows... Figure 4 As shown, Figure 4This is a schematic diagram of a pump shut-off process provided in an embodiment of this specification. The method further includes:

[0073] S401: Obtain the real-time temperature value collected by the first temperature sensor.

[0074] In the embodiments of this specification, as water flows from the heating tank into the heat exchanger, and the power conversion device in the heat exchanger converts the heat energy carried by the water in the heat exchanger into electrical energy, the first temperature sensor continuously detects the water temperature value in the heat exchanger, that is, obtains the real-time temperature value, and achieves precise control of the pump body by obtaining the real-time temperature value.

[0075] S402: If the real-time temperature value is less than the preset temperature value, control the pump to turn on, obtain the second turn-on duration corresponding to the pump, and draw water from the heat dissipation box into the second cavity of the heating water tank.

[0076] In the embodiments of this specification, when the real-time temperature value is less than the preset temperature value, that is, when the water temperature in the heat sink is less than 40°C, the pump body, i.e., the DC pump, is turned on, so that the cooled water in the heat sink is drawn back to the right side of the heating water tank, i.e., the second cavity, through the second pipeline. The water in the heat sink flows out in a set direction through the four cavities formed by the first partition, the second partition, and the third partition, so that the cold water in the heat sink can flow out first, avoiding mixing with the hot water in the heat sink. At the same time, the second opening time corresponding to the pump body is obtained to prevent the water in the heat sink from flowing out too much or too little.

[0077] S403: If the second opening duration is greater than or equal to the preset opening duration, control the pump body to close.

[0078] In this embodiment, the preset start-up time is 30 seconds. When the pump's start-up time reaches 30 seconds, i.e., the second start-up time is greater than or equal to 30 seconds, the pump is controlled to shut down. Here, 30 seconds is only a preset duration; in actual use, the pump's start-up time can be adjusted according to the water volume in the heat exchanger tank. Ultimately, this ensures that all the used cold water in the heat exchanger tank flows into the second chamber of the heating water tank. By acquiring the real-time temperature value within the heat exchanger tank, the water in the heat exchanger tank is promptly transferred to the heating water tank after use, facilitating the subsequent transfer of hot water from the heating water tank to the heat exchanger tank for power generation, thus improving the water purifier's efficiency.

[0079] In one exemplary implementation, such as Figure 5 As shown, Figure 5 A flowchart illustrating a standby method for a water purifier provided in this embodiment of the specification includes:

[0080] S501: By default, if no one uses the water purifier for more than one hour after midnight, the energy-saving mode will be activated.

[0081] In the embodiments of this specification, the frequency of users using the water purifier will generally decrease significantly after 0:00 AM. Therefore, it can be set that the water purifier will turn on the energy-saving mode after 0:00 AM and after no one has used the water purifier for more than one hour.

[0082] S502: Determine if the value of temperature sensor 1 is greater than 40℃.

[0083] In the embodiments of this specification, the heating water tank is located on the top of the water purifier. A partition is installed inside the heating water tank, which divides the heating water tank into two parallel cavities, which can be cavity 1 and cavity 2. A heating plate and a temperature sensor 1 are installed in cavity 1. Both the heating plate and the temperature sensor 1 are electrically connected to the controller of the water purifier. The temperature sensor 1 is used to detect the water temperature value in the heating water tank. By determining whether the water temperature value in the heating water tank is greater than 40°C, the next step is performed.

[0084] S503: Open the hot water valve and DC pump for 30 seconds to fill the radiator with hot water.

[0085] In this embodiment of the specification, a heat dissipation box is provided at the bottom of the water purifier. The heat dissipation box contains three partitions, dividing it into four interconnected cavities, which can be cavities 3, 4, 5, and 6. This restricts the water flow direction within the heat dissipation box, allowing hot water to flow in while cold water flows out. An outlet 1 is provided at the bottom of cavity 1 in the heating water tank, and an inlet 1 is provided at the top of cavity 3 in the heat dissipation box. A heat dissipation box inlet pipe is provided between the heating water tank and the heat dissipation box, with one end connected to the outlet 1 and the other end connected to the inlet 1. A hot water valve is provided on the side of the heat dissipation box inlet pipe near cavity 1. This hot water valve... The water purifier's controller is electrically connected. When the hot water valve is open, hot water from the heating tank flows into the heat exchanger. When the hot water valve is closed, no more hot water flows into the heat exchanger. The top of the cavity 2 in the heating tank has an inlet 2, and the top of the cavity 6 in the heat exchanger has an outlet 2. A heat exchanger outlet pipe is also provided between the heating tank and the heat exchanger, with one end connected to the outlet 2 and the other end connected to the inlet 2. A DC pump is provided on the side of the heat exchanger outlet pipe near the cavity 2. The DC pump is electrically connected to the water purifier's controller. When the DC pump is turned on, water in the heat exchanger is drawn into the heating tank. When the DC pump is turned off, water in the heat exchanger is no longer discharged. When the water temperature in the heating tank exceeds 40℃, it indicates that the water in the tank carries heat energy. At this time, both the hot water valve and the DC pump are opened for 30 seconds, allowing hot water to flow into the radiator through the inlet pipe, filling the radiator with hot water. Simultaneously, the thermoelectric generator attached to the outside of the radiator converts the heat energy carried by the hot water into electrical energy, and the radiator promptly discharges the used cold water through the outlet pipe, preventing the radiator from becoming overfilled. In actual use, the opening time of the hot water valve and the DC pump does not have to be 30 seconds. The opening time depends on the amount of water in the radiator. 30 seconds is just an example. If the radiator only needs the hot water valve to be open for 30 seconds and the DC pump to be open for 20 seconds to fill it with water, then the hot water valve should be opened for 30 seconds and the DC pump for 20 seconds.

[0086] S504: Determine whether the value of temperature sensor 2 is less than 40℃.

[0087] In the embodiments of this specification, a temperature sensor 2 is installed inside the heat dissipation box. The temperature sensor 2 is electrically connected to the controller of the water purifier. The temperature sensor 2 is used to detect the water temperature value inside the heat dissipation box. When the heat dissipation box is filled with hot water, it is determined whether the value of the temperature sensor 2 is less than 40°C.

[0088] S505: Turn on the DC pump for 30 seconds to pump the cooled water in the radiator back to the right side of the heating water tank.

[0089] In this embodiment, when the temperature sensor 2 value is less than 40°C, the heat energy carried by the water in the heat sink has been converted into electrical energy by the thermoelectric generator, and the hot water becomes cold water. Therefore, the DC pump is turned on for 30 seconds to draw the cooled water in the heat sink back to the right side of the heating water tank, i.e., cavity 2. During the extraction process, the water in the heat sink flows along the predetermined direction formed by the four cavities separated by three partitions, ensuring that the colder water flows out first. The 30 seconds here is a preset duration; the actual operating time of the DC pump depends on the amount of water in the heat sink. Here, it is only to draw all the cold water in the heat sink into cavity 2 of the heating water tank.

[0090] S506: Open the hot water valve for 30 seconds to refill the radiator with hot water.

[0091] In the embodiments described in this specification, after all the water in the heat exchanger tank has been drawn into the heating water tank, the hot water valve is opened for 30 seconds, allowing water from the heating water tank to flow into the heat exchanger tank through the inlet pipe, thus refilling the heat exchanger tank with hot water. This 30-second time is merely a preset duration to ensure the heat exchanger tank is fully filled with hot water; it can be adjusted according to actual usage. Simultaneously, when hot water enters the heat exchanger tank, the thermoelectric generator, which is attached to the outer surface of the heat exchanger tank, utilizes the temperature difference between its two sides to convert the heat energy carried by the hot water into electrical energy. This converted electrical energy is then transmitted to the energy storage box located at the bottom of the heat exchanger tank to charge the battery within. This allows the water purifier to operate in standby mode, reducing its operating time and saving energy.

[0092] S507: Determine if the value of temperature sensor 1 is less than 40℃; if the value of temperature sensor 1 is greater than or equal to 40℃, proceed to S504.

[0093] In the embodiments of this specification, when the heat sink is filled with hot water, the value collected by the temperature sensor 1 in the heating water tank is obtained, and it is determined whether the value of the temperature sensor 1 is less than 40°C, so as to determine the subsequent control strategy.

[0094] S508: Energy saving mode is off. Power generation is complete. Waiting for 0:00 the next day.

[0095] In the embodiments of this specification, if the value detected by temperature sensor 1 is less than 40°C, it indicates that the water in the heating tank is cold water. Therefore, the thermoelectric generator on the outside of the heat sink no longer generates electricity, and the power generation process is completed. At this time, the energy-saving mode is turned off, and the water purifier is put into standby mode by using the electrical energy stored in the energy storage box at 0:00 the next morning. When the user needs to use the water purifier normally, the power supply is switched to mains power.

[0096] In this embodiment, when the water purifier is not in use during the early morning, it is controlled to enter an energy-saving mode. By continuously monitoring the water temperature in the heating tank and the water temperature in the heat dissipation tank, hot water from the heating tank flows into the heat dissipation tank through the inlet pipe. Thermoelectric generators attached to the outside of the heat dissipation tank generate electricity, which powers a battery in the energy storage box. This allows the water purifier to enter standby mode, maximizing the utilization of the heat carried by the water in the heating tank, reducing power consumption, and saving energy. Simultaneously, real-time monitoring of the water temperature in the heat dissipation tank ensures that the cold water is drained from the heat dissipation tank as soon as possible after use, improving the power generation efficiency of the water purifier.
