[0035] Example 1

[0036] This embodiment provides a waterway structure, such as... Figure 1 As shown, it includes a heating water circuit;

[0037] The heating water circuit includes a first heating branch 100, a second heating branch 200, and a main heating water circuit 300;

[0038] The first heating branch 100 and the second heating branch 200 are connected in parallel;

[0039] The first heating branch 100 includes a heating water tank 110, which is used to heat the water flow to a first temperature range;

[0040] The second heating branch 200 includes a flow regulation module 210, which is used to allocate the ambient temperature water inlet volume of the second heating branch 200;

[0041] The outlet of the first heating branch 100 and the outlet of the second heating branch 200 are connected to the main heating water circuit 300;

[0042] The main heating water circuit 300 includes a main heater 310, which is used to heat the water flow of the second heating branch 200 to a second temperature range; or, it is used to heat the water flow of the first heating branch 100 to a third temperature range.

[0043] Wherein, the second temperature range is smaller than the first temperature range, and the first temperature range is smaller than the third temperature range.

[0044] In this solution, hot water for the first temperature range is supplied through the heating water tank 110 in the first heating branch 100. Hot water for the second temperature range is quickly supplied through the second heating branch 200 and the main heater 310. For hot water demanded by the user that is higher than the first temperature range, the hot water in the heating water tank 110 is quickly heated to the third temperature range by the main heater 310, thus achieving rapid supply of hot water at different temperatures. The main heater 310 can be a thick-film heating element, which, due to its high power density, can quickly provide hot water for either the second or third temperature range.

[0045] Meanwhile, when the hot water in the heating water tank 110 is depleted, the flow rate regulation module 210 in the second heating branch 200 can be used to distribute the flow rate into the first heating branch 100 and the second heating branch 200. This replenishes the heating water tank 110 while simultaneously supplying water directly from the second heating branch 200 to the main heater 310 for heating, continuously providing hot water within the first temperature range. The flow rate regulation module 210 in the second heating branch 200 can be a water valve assembly, which adjusts in real time according to the water level in the heating water tank 110. The heating water tank 110 has a first outlet valve 112 at its outlet and a first inlet valve 111 at its inlet.

[0046] In one embodiment, if the water level in the heating water tank 110 is lower than the preset water replenishment level, the opening of the first water outlet valve 112 is adjusted, and water is supplied simultaneously through the first heating branch 100 and the second heating branch 200. The water outlet temperature is maintained in the first temperature range when the main heater 310 is used, while ensuring the water flow rate.

[0047] In one embodiment, if the user's required temperature is in the third temperature range, hot water from the heating tank 110 in the first heating branch 100 is first supplied, and the main heater 310 heats the hot water to the third temperature range. When the water level in the heating tank 110 is lower than the preset water replenishment level, the opening of the first outlet valve 112 is adjusted, and water is supplied simultaneously through the first heating branch 100 and the second heating branch 200. The outlet water temperature is maintained in the third temperature range using the main heater 310, and the water supply flow is maintained to improve the user experience.

[0048] As one possible implementation, the waterway structure also includes a filtration device 400;

[0049] The outlet of the filter device 400 is connected to the heating water circuit, and the filter device 400 is used to filter the water flowing into the heating water circuit.

[0050] In this solution, the filtration device 400 removes impurities, harmful chemicals, and microorganisms from the incoming water flow in the water system, improving the taste of the final water supply and ensuring the safety, purity, and health of the water.

[0051] As one possible implementation, the water circuit structure includes a first return branch 500, the inlet of the first return branch 500 being connected to the outlet of the heating water circuit, and the outlet of the first return branch 500 being connected to the filter device 400.

[0052] The first return branch 500 and the heating water circuit form a zero-cold water circuit.

[0053] In this solution, when the water supply is stopped, the residual water in the heating pipe is returned to the filter device 400 through the first return branch 500 to empty the heating water pipe and avoid waiting time for the next water supply. In one embodiment, after the residual water in the heating water circuit is drained, the main heater 310 heats the heating water pipe to dry it, making the inside of the water pipe dry and preventing bacteria from growing in the residual water stains inside the heating water pipe, thus ensuring the quality of the supplied water.

[0054] As one possible implementation, the water circuit structure includes a second return branch 600, the inlet of which is connected to the drain of the heating water tank 110, and the outlet of which is connected to the filter device 400.

[0055] In this scheme, wastewater to be discharged from the heating water tank 110 is returned to the inlet side of the filter device 400 via the second return branch 600 to flush the filter device 400. After the water supply is stopped, when the temperature of the heating water tank 110 meets the flushing temperature of the filter device 400, the wastewater in the heating water tank 110 is drained through the drain outlet of the heating water tank 110 via the second return branch 600, and hot air is discharged through the exhaust pipe of the heating water tank 110 to flush the filter device 400. This avoids the hot water in the heating water tank 110 from sitting for too long, which can breed bacteria, and avoids the hot water in the heating water tank 110 from being repeatedly heated, which could lead to water quality deterioration.

[0056] In one possible implementation, the filtration device 400 includes a pre-filtration module 410, a membrane filter element 420, and a post-filtration module 430 connected in sequence.

[0057] A first water pump 440 is provided between the pre-filter module 410 and the membrane filter element 420.

[0058] In this solution, the pre-filtration module 410 effectively removes large particulate impurities in the water, such as silt and rust, reducing clogging of the membrane filter element 420. Building upon the pre-filtration, the membrane filter element 420 further removes tiny particles, bacteria, viruses, and other harmful substances from the water, ensuring water purity. The post-filtration module 430 further improves the taste of the water, removing any residual odors and organic matter, providing higher-quality drinking water. The first water pump 440, positioned between the pre-filtration module 410 and the membrane filter element 420, ensures the stability of the water flow and the uniformity of the pressure, improving the efficiency and stability of the entire filtration device 400. Simultaneously, the first water pump 440 also pumps the return water flow from the first return branch 500 and the second return branch 600, achieving zero cold water in the water circuit structure and emptying the heating water tank 110.

[0059] As one possible approach, the pre-filtration module 410 is a pleated polypropylene carbon filter, the membrane filter element 420 is a nanofiltration membrane filter element 420, and the post-filtration module 430 is a carbon rod ultrafiltration composite filter element.

[0060] In this solution, pleated polypropylene carbon is used to effectively remove large particulate impurities from water due to its high filtration accuracy and large filtration area. Nanofiltration membranes have a microporous structure that can effectively remove suspended particles, colloidal substances, and high molecular weight organic matter from water, while retaining minerals and dissolved ions. The carbon rod ultrafiltration composite filter combines the high-efficiency adsorption performance of activated carbon with the filtration function of ultrafiltration membranes, which can further remove odors, organic matter, and small particles from water, improving the taste and purity of the water.

[0061] In one possible implementation, the main heating water circuit 300 includes a second water pump 330 and a flow meter 320;

[0062] The second water pump 330 is used to pump water from the first heating branch 100 and / or the second heating branch 200 to the main heater 310 for heating.

[0063] In this scheme, the water flow rate in the heating water circuit is adjusted by the second water pump 330, and the flow rate of the first hot water branch and / or the second hot water branch is collected by the flow meter 320, so as to adjust the first outlet valve 112 of the first hot water branch and / or the flow regulation module 210 of the second hot water branch according to the inlet water flow. In one embodiment, the heating main water circuit 300 is also equipped with an outlet water thermometer at the outlet of the second water pump 330 to collect the outlet water temperature of the heating water circuit, so as to accurately control the outlet water temperature and flow rate.

[0064] As one possible implementation, the water circuit structure also includes a room temperature water circuit 700, which is connected in parallel with the heating water circuit.

[0065] In this solution, room temperature water is rapidly supplied through parallel room temperature water circuits 700.

[0066] As one possible implementation, the heated water tank 110 includes a water level probe 113 and a sterilization module.

[0067] In this solution, the water level in the heating water tank 110 is monitored in real time by a water level probe 113. Based on this, the heating water tank 110 is replenished, shut off, or drained accordingly, achieving precise control of the water level. The sterilization module effectively kills bacteria and microorganisms in the water, ensuring water quality safety.

[0068] The water circuit structure provided in this embodiment provides hot water supply in different temperature ranges through the first heating branch 100, the second heating branch 200, and the main heater 310; and uses the first heating branch 100 to supplement the heating water tank 110, extending the water supply to the heating water tank 110 and ensuring the water supply flow. It has a zero-cold-water circuit to ensure stable outlet water temperature, and uses the main heater 310 to dry the drained main heating water circuit 300, maintaining the hygiene of the water circuit and improving the health of the supplied water quality.

[0069] Example 2

[0070] This embodiment provides a water purifier that includes the water circuit structure of Embodiment 1.

[0071] In this solution, the water purifier is an integrated purification and heating unit that provides hot water supply in multiple temperature ranges through its water circuit structure.

[0072] The water purifier provided in this embodiment provides hot water supply in different temperature ranges through the first heating branch 100, the second heating branch 200, and the main heater 310 in the water circuit structure; and uses the first heating branch 100 to supplement the heating water tank 110, extending the water supply to the heating water tank 110 and ensuring the water supply flow. It has a zero-cold-water circuit to ensure stable outlet water temperature, and uses the main heater 310 to dry the drained main heating water circuit 300, maintaining the hygiene of the water circuit and improving the health of the supplied water quality.
