[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] like Figure 1The illustrated drinking water heating assembly includes at least two heat storage tanks 100 and at least two heat exchangers 200. Each heat storage tank 100 is provided with an outlet 12, an inlet 11, and a heat storage cavity for accommodating the heat exchange medium. Both the outlet 12 and the inlet 11 are connected to the heat storage cavity. Each heat exchanger 200 is provided with a heat exchange medium channel 21 and a water flow channel 22. The two ends of the heat exchange medium channel 21 are connected to the inlet 11 and the outlet 12, respectively. The heat exchange medium channel 21 and the water flow channel 22 are isolated from each other. It can be understood that, for... To allow the heat exchange medium to circulate between the heat storage tank 100 and the heat exchanger 200, a water pump 01 is installed between the heat storage tank 100 and the heat exchanger 200. The heat exchange medium flows out through the outlet 12, then enters the heat exchanger 200 from one end of the heat exchange medium channel 21, and flows out of the heat exchanger 200 from the other end of the heat exchange medium channel 21, returning to the heat storage tank 100 through the inlet 11. At least two heat exchangers 200 are connected in parallel or in series, and each heat exchanger 200 is connected to at least one heat storage tank 100. Through this design, at least two heat exchangers 200 can more efficiently transfer the heat of the heat exchange medium to drinking water, thereby improving the heating efficiency of drinking water. For ease of description, this drinking water heating assembly is illustrated with two heat exchangers. As described above, the two heat exchangers 200 can be connected in series or in parallel. Different connection methods of the two heat exchangers 200 can produce different application effects, thus meeting more usage requirements.

[0029] Specifically, if the two heat exchangers 200 are connected in series, the drinking water is heated by one heat exchanger 200 and then by the other heat exchanger 200, thus heating the drinking water more thoroughly. In practical applications, this allows the drinking water to be heated to a relatively high temperature and is suitable for dispensing hot water for extended periods. If the two heat exchangers 200 are connected in parallel, the drinking water can be heated by each heat exchanger 200 separately. When the temperature of the storage tank 100 connected to one heat exchanger 200 is insufficient, the other heat exchanger 200 can be used to heat the drinking water, thereby continuously obtaining high-temperature water. In practical applications, this is suitable for dispensing small amounts of water multiple times in a short period of time, and each dispensing can produce high-temperature water.

[0030] In some embodiments, the heat storage tank 100 of the drinking water heating assembly provided in this application is connected one-to-one with the heat exchanger 200, and the maximum temperature of the heat exchange medium contained inside the different heat storage tanks 100 is different. For ease of explanation, the heat exchanger 200 connected to the heat storage tank 100 with a higher maximum temperature of the heat exchange medium is a high-temperature heat exchanger 200, and the heat exchanger 200 connected to the heat storage tank 100 with a lower maximum temperature of the heat exchange medium is a low-temperature heat exchanger 200. When the user needs drinking water at a low temperature (e.g., for direct drinking), the low-temperature heat exchanger 200 can be used to heat the drinking water. The temperature of the heat exchange medium inside the heat storage tank 100 connected to the low-temperature heat exchanger 200 is low, and the drinking water will not be heated to a high temperature. The heat storage tank 100 connected to the high-temperature heat exchanger 200 can always store enough heat so that the user can obtain high-temperature water. The above methods can meet more user needs. At the same time, since the hot water is released through the low-temperature heat exchanger 200, it will not affect the heat storage tank 100 connected to the high-temperature heat exchanger 200. Therefore, when users need high-temperature water, they do not need to reheat it. They can directly heat it through the high-temperature heat exchanger 200 to obtain hot water at a higher temperature without waiting for reheating, thereby improving the heating efficiency of drinking water.

[0031] In some embodiments, the heat exchange medium inside each heat storage tank 100 has a different material composition. As is well known, in daily life, heat exchange media with different compositions have different boiling points. The boiling point of water is 100 degrees Celsius under standard atmospheric pressure. When water is used as the heat exchange medium, it is difficult to heat drinking water to 90 degrees Celsius or even close to 100 degrees Celsius because the liquid inside the water flow channel 22 is in a flowing state. However, if a liquid with a higher boiling point than water is used as the heat exchange medium, for ease of explanation, "oil" will be used as an example below. The heat storage tank 100 is equipped with a heating device that can heat the oil to above 100 degrees Celsius. When the oil flows through the heat exchange medium channel 21, the drinking water inside the water flow channel 22 can obtain more heat. By controlling the flow rate of drinking water and oil, the heating temperature of the drinking water can be close to 100 degrees Celsius. Therefore, compared with using water as the heat exchange medium, the drinking water can be heated to a temperature close to 100 degrees Celsius more quickly, thus improving the heating efficiency of heating high-temperature water.

[0032] It should be noted that the use of "oil" in the above description is for ease of description only. This application does not limit the type of heat exchange medium itself. The heat exchange medium can also be any liquid with a boiling point higher than water, other than "oil".

[0033] In some embodiments, the drinking water heating assembly includes two heat exchangers 200, designated as section A and section B, which are connected in series or parallel via water flow channels 22. The assembly also includes a flow divider 300 positioned between sections A and B. The flow divider 300 can be switched from a parallel to a series configuration. Specifically, when the flow divider is in series, the water flow channels 22 of sections A and B are connected in series; when it is in parallel, the water flow channels 22 of sections A and B are connected in parallel. The flow divider 300 can switch the connection method of the two heat exchangers 200 in sections A and B according to usage requirements, thereby improving the applicability of the drinking water heating assembly.

[0034] Specifically, the aforementioned water flow channel 22 has an inlet 211 at one end and an outlet 212 at the other end; the aforementioned diversion assembly 300 includes a first diversion valve 31 and a second diversion valve 32. The first diversion valve 31 is connected to the outlet 212 of section A, and the second diversion valve 32 is connected to the inlet 211 of section B. The first diversion valve 31 and the second diversion valve 32 can be selectively connected to each other. The switching method of the diversion assembly 300 is described in detail below:

[0035] When the water flow channels 22 of sections A and B need to be connected in series, the first diversion valve 31 and the second diversion valve 32 are connected, as shown in the figure. After the drinking water flows out of the outlet 212 of section A, it flows into the second diversion valve 32 through the first diversion valve 31, then into the inlet 211 of section B, and finally flows out from the outlet 212 of section B. Through the above process, the drinking water is heated by the two heat exchangers 200, and thus can be heated more fully.

[0036] When the water flow channels 22 of sections A and B need to be connected in parallel, the first diversion valve 31 and the second diversion valve 32 are disconnected, and drinking water can flow into the water flow channels 22 of the two heat exchangers 200 of sections A and B as needed, and then be discharged directly from their respective water flow channels 22.

[0037] In summary, the diversion component 300 can switch the connection mode of the water flow channels 22 of the two heat exchangers 200, thereby enabling the heating component to adapt to various hot water needs in daily life, and improving the heating efficiency of drinking water from a practical application perspective.

[0038] In some embodiments, the drinking water heating assembly provided in this application further includes a control module, which is connected to the first diversion valve 31 and the second diversion valve 32. Users can control the first diversion valve 31 and the second diversion valve 32 through the control module. Specifically, the control module includes a touch panel and an electronic module. The touch panel has multiple touch points, and the electronic module is electrically connected to the touch panel, the first diversion valve 31, and the second diversion valve 32. Each touch point corresponds to a connection method of the water flow channels 22 of the two heat exchangers 200. Users can switch the connection method of the water flow channels 22 of the two heat exchangers 200 by touching the touch points as needed, and then dispense the required hot water.

[0039] In some embodiments, the drinking water heating assembly provided in this application further includes a heat replenishment assembly 400, which is connected in series with the heat exchanger 200. The heat replenishment assembly 400 is provided with a heat replenishment pipe and a first electric heating element, with the first electric heating element disposed close to the heat replenishment pipe. It is understood that the heat exchange medium inside the heat storage tank 100 stores a limited amount of heat. When the temperature of the heat exchange medium decreases, the heat exchanger 200 can no longer effectively heat the drinking water. The heat replenishment assembly 400 can supplement the heat of the drinking water through the first electric heating element, so that more hot water can be continuously obtained.

[0040] This application provides a water supply device, including the aforementioned drinking water heating component.

[0041] In some embodiments, the water supply device further includes a rapid heating component connected in series with the drinking water heating component. The rapid heating component is equipped with a rapid heating pipe and a second heating element, which is located close to the rapid heating pipe. It is understood that the rapid heating component can further heat the drinking water when the heat provided by the drinking water heating component is insufficient, thus facilitating the production of hot water at a higher temperature.

[0042] In some embodiments, the water supply device is provided with an inlet valve and an outlet valve. The inlet valve may be selectively connected to the water flow channel 22 of one or at least two heat exchangers 200, and the outlet valve may be selectively connected to the water flow channel 22 of one or at least two heat exchangers 200.

[0043] Specifically, solenoid valves are installed between the inlet 211 and the inlet valve of the water flow channel 22 of the two heat exchangers 200, and solenoid valves are also installed between the outlet 212 and the outlet valve of the water flow channel 22 of the two heat exchangers 200. It can be understood that by opening and closing the solenoid valves, drinking water can be controlled to flow into either heat exchanger 200, and drinking water can also flow into both heat exchangers 200 at the same time for heating, thus realizing multiple heating methods.
