[0039] Example 1

[0040] This embodiment provides a waterway structure, such as Figure 1 As shown, it includes: a water storage tank 3, a cold water tank 4, a hot water pipe 1, and a cold water pipe 2;

[0041] The inlet of the hot water pipe 1 is connected to the water storage tank 3, and the hot water pipe 1 is connected to the cold water pipe 2 for heating the water flowing into the hot water pipe 1;

[0042] The inlet end of the cold water pipe 2 is connected to the cold water tank 4. A cold water valve 21 is provided on the cold water pipe 2. The cold water pipe 2 is used to introduce the water into the cold water tank 4 for cooling.

[0043] The hot water pipe 1 and the cold water pipe 2 share the same outlet valve 5.

[0044] In this scheme, hot water pipe 1 is connected to cold water pipe 2, allowing the water in hot water pipe 1 and cold water pipe 2 to flow between each other. This enables the use of cold water in cold water pipe 2 to quickly cool the hot water in hot water pipe 1, or to pour hot water from hot water pipe 1 into cold water pipe 2 for temperature control. With the outlet valve 5 closed, the water storage tank 3, cold water tank 4, hot water pipe 1, and cold water pipe 2 are integrated into a closed-loop water circuit structure to regulate the overall temperature of the water in the water circuit structure, maintain a consistent outlet water temperature, and meet the outlet water temperature requirements.

[0045] In one possible implementation, the hot water pipe 1 includes a heating element 11;

[0046] The heating element 11 is provided with a first temperature sensor 12 at its water inlet and a second temperature sensor 13 at its water outlet.

[0047] The heating element 11 is used to heat the raw water flowing into the water storage tank 3, or to mix the cold water flowing into the cold water pipe 2.

[0048] The first temperature sensor 12 is used to detect the water temperature flowing into the heating element 11 from the water storage tank 3;

[0049] The second temperature sensor 13 is used to detect the outlet water temperature of the heating element 11.

[0050] In this scheme, the heating element 11 heats the raw water flowing into the hot water pipe 1 from the storage tank 3. Cold water from the cold water pipe 2 can be poured back from the outlet of the heating element 11 to cool the hot water in the heating element 11. The final outlet water temperature is detected by the second temperature sensor 13 at the outlet of the heating element 11. When the outlet water temperature meets the water supply requirements, the cold water valve 21 is closed and the outlet valve 5 is opened to supply water to the user.

[0051] As one possible implementation, the hot water pipe 1 also includes a hot water pump 14 and a flow meter 15;

[0052] The hot water pump 14 is located on the inlet side of the heating element 11 and is used to pump raw water to the heating element 11.

[0053] The flow meter 15 is installed between the hot water pump 14 and the heating element 11 to detect the flow rate of the pumped raw water.

[0054] In this scheme, the hot water pump 14 installed in the hot water pipeline 1 pumps the raw water in the water storage tank 3 to the heating element 11, or the hot water pump 14 in the heating element 11 pumps the water to the cold water pipeline 2. The flow rate pumped by the hot water pump 14 is detected by the flow meter 15 to control the flow rate flowing from the heating element 11 into the cold water pipeline 2, thereby improving the temperature control accuracy in the water circuit structure.

[0055] In one possible arrangement, the cold water tank 4 is connected to the water storage tank 3, with the water storage tank 3 positioned higher than the cold water tank 4.

[0056] The cold water tank 4 is used to process the raw water flowing into the water storage tank 3 into cold water.

[0057] In this solution, the water storage tank 3 serves as the water source for the entire water circuit structure, providing heating water for the hot water pipe 1 and cooling water for the cold water pipe 2. This simplifies the water inlet pipes of the water circuit structure, coordinates the overall water usage of the water circuit structure through a single water source, controls the quality of the raw water, and improves the user experience.

[0058] As one possible approach, the cold water tank 4 is a cold liner.

[0059] In this solution, the cold tank 4 is used as the cold water tank to achieve rapid cooling. The cold tank is small in size, light in weight, vibration-free and noiseless, and easy to install and maintain, enabling the cold water pipeline 2 to achieve efficient cooling and energy saving.

[0060] As one possible approach, the outlet of the cold water tank 4 is located on the top surface of the cold water tank 4;

[0061] A baffle 41 is provided at the outlet of the cold water.

[0062] In this solution, a baffle 41 is installed on the side where the cold water tank 4 is connected to the cold water pipe 2, that is, on the side of the outlet of the cold water tank 4, to prevent hot water in the hot water pipe 1 from flowing into the cold water tank 4 too quickly, causing the temperature of the cold water tank 4 to rise too quickly, thus protecting the cold water tank 4.

[0063] As one possible approach, the cold water tank 4 is equipped with a sterilization unit 42.

[0064] In this solution, the cold water in the cold water tank 4 is treated with bacteria by the sterilization unit 42, especially psychrophilic bacteria and antifreeze bacteria. The sterilization unit 42 can be an ultraviolet sterilization unit 42, so as to avoid the contamination of the water by bacteria in the cold water when supplying warm water and cold water.

[0065] In one possible implementation, the cold water line 2 includes a cold water pump 22 and a third temperature sensor 23;

[0066] The cold water pump 22 is used to send the cold water pump 22 in the cold water tank 4 out of the cold water pipeline 2;

[0067] The third temperature sensor 23 is located on the inlet side of the cold water pump 22 and is used to detect the outlet water temperature of the cold water tank 4.

[0068] In this scheme, the cold water pump 22 in the cold water tank 4 is used to send cold water to the heating element 11 in the hot water pipeline 1, or the cold water pump 22 in the cold water tank 4 supplies cold water. The third temperature sensor 23 detects the outlet water temperature of the cold water tank 4, which is used to detect the temperature of the cold water pumped out of the cold water tank 4, or the temperature of the warm water cooled after being backflowed into the cold water tank 4 from the hot water pipeline 1. This achieves precise control of the outlet water temperature.

[0069] As one possible approach, a liquid level sensor is installed inside the water storage tank 3.

[0070] In this scheme, the water storage tank 3 includes at least a low-level sensor 32, and may also include a high-level sensor 31 and several preset monitoring level sensors. The signals from each level sensor in the water storage tank 3 are used to replenish or stop water replenishment. This prevents the raw water in the water storage tank 3 from running out or overflowing, thereby achieving automated control of the water level in the water storage tank 3 and improving the ease of use of the water system structure.

[0071] The following specific embodiment illustrates how the waterway structure provided in this embodiment works:

[0072] After the initial flushing logic is executed in the water circuit structure and a low water level is detected in the storage tank 3, the following logic is added: the hot water pump 14 and the cold water valve 21 are energized, filling the hot water pipe 1 and the cold water pipe 2 with clean water, greatly reducing the water replenishment time. After the high water level sensor in the storage tank 3 triggers a signal, water supply to the storage tank 3 is stopped, and the hot water pump 14 and the cold water valve 21 are de-energized, isolating the hot water pipe 1 and the cold water pipe 2. Simultaneously, the second temperature sensor 13 detects the hot water temperature at the outlet of the heating element 11. If the detected hot water temperature is less than 45 degrees Celsius, the heating element 11 is energized to heat the raw water. When the hot water temperature reaches 45 degrees Celsius, the heating element 11 is de-energized.

[0073] Upon receiving the instruction for the required outlet water temperature, the water circuit first determines whether the required outlet water temperature falls within the cold water temperature range. If the required outlet water temperature falls within the cold water temperature range, the cold water pump 22 and cold water valve 21 are energized, causing cold water in the cold water tank 4 to flow back into the heating element 11 until the hot water temperature detected by the second temperature sensor 13 is the same as the cold water temperature detected by the third temperature sensor 23. Then, the outlet valve 5 is energized and opens, providing cold water supply. Once the user stops dispensing water, the outlet valve 5 is de-energized, and the cold water pump 22 and cold water valve 21 are energized again until the raw water temperature detected by the first temperature sensor 12 is the same as the cold water temperature detected by the third temperature sensor 23. Then, the cold water pump 22 and cold water valve 21 are de-energized. Finally, the control logic to heat the heating element 11 to 45 degrees Celsius is executed.

[0074] If the required outlet water temperature does not fall within the cold water temperature range, it is determined whether the required outlet water temperature falls within the normal temperature range. If it does not fall within the normal temperature range, the hot water pump 14, heating element 11, and cold water valve 21 are energized, causing the heating element 11 to heat the water. The heated water is then poured back into the cold tank for temperature regulation until the hot water temperature detected by the second temperature sensor 13 matches the required outlet water temperature. At this point, the cold water valve 21 is de-energized, the outlet valve 5 is energized, and the water circuit supplies water until the user stops the water flow. Then, the control logic to heat the heating element 11 to 45 degrees Celsius is executed.

[0075] If the required outlet water temperature falls within the normal temperature range, the hot water pump 14 and cold water valve 21 are de-energized, while the outlet valve 5 is energized, directly supplying water from the normal temperature water in the storage tank 3 until the user stops the water flow. Then, the control logic for heating the heating element 11 to 45 degrees Celsius is executed.

[0076] In this embodiment, the heating element can be a heating tank.

[0077] The water circuit structure provided in this embodiment regulates the overall temperature of the water in the water circuit structure through the interconnected hot water pipe 1 and cold water pipe 2. The hot water pump 14, cold water valve 21 and cold water pump 22 quickly adjust the water supply temperature of the water circuit structure so that the outlet water temperature meets the user's needs and remains consistent, shortens the water replenishment time, and maintains a stable and adjustable flow rate.

[0078] Example 2

[0079] This embodiment provides a water purifier, which includes the water circuit structure described in Embodiment 1.

[0080] The water purifier provided in this embodiment regulates the overall temperature of the water in the water circuit structure through the interconnected hot water pipe 1 and cold water pipe 2. The hot water pump 14, cold water valve 21 and cold water pump 22 quickly adjust the water supply temperature of the water circuit structure so that the outlet water temperature meets the user's needs and remains consistent, shortens the water replenishment time, and maintains a stable and adjustable flow rate.
