[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] like Figure 1 The heating device shown includes a heat exchanger 100 and a heat storage tank 200. The heat exchanger 100 is provided with a medium channel 11 and a water flow channel 12 arranged at intervals. The medium channel 11 is used for the flow of heat exchange medium, and the water flow channel 12 is used for the flow of drinking water. The heat storage tank 200 is provided with at least two heat exchange tubes 21. The heat storage tank 200 has a heat storage cavity for accommodating the heat exchange medium. Each heat exchange tube 21 is connected to the heat storage cavity. The heat exchange medium can flow out of the heat storage tank 200 from the heat storage cavity through the heat exchange tubes 21. The medium channel 11 is selectively connected to the at least two heat exchange tubes 21 through pipes. The heat exchange medium can flow into the medium channel 11 of the heat exchanger 100 through the heat exchange tubes 21. Since the medium channel 11 and the water flow channel 12 are arranged at intervals, the heat of the heat exchange medium can be transferred to the drinking water in the water flow channel 12 through the medium channel 11, thereby heating the drinking water. The heating device provided in this application allows the heat exchange medium to be transported into the heat exchanger 100 through multiple heat exchange tubes 21 during the process of the heat exchange medium entering the heat exchanger 100 from the heat storage tank 200. This enables the heat exchange medium to enter the heat exchanger 100 more quickly, thereby improving the heat exchange efficiency of the heat exchanger 100, that is, improving the heating efficiency of drinking water.

[0026] The technical details of each component will be introduced below.

[0027] To further improve heating efficiency, in some embodiments, the flow directions of the liquid in the water flow channel 12 and the medium channel 11 are opposite.

[0028] In some embodiments, at least two heat exchange tubes 21 are connected to different locations in the heat storage tank 200. In practical applications, since the heat exchange medium is liquid, the temperature of the heat exchange medium inside the heat storage tank 200 changes during the circulation process between the heat exchanger 100 and the heat storage tank 200. Along the direction of gravity, the temperature of the heat exchange medium located at the top of the heat storage cavity is higher than that located at the bottom. The heat exchange tubes 21 are connected to the top of the heat storage cavity. By setting multiple heat exchange tubes 21 and connecting them to different locations in the heat storage tank 200, the heat exchange medium can flow into the heat exchanger 100 from multiple points, thereby making the flow of the heat exchange medium inside the heat storage cavity more uniform. This reduces the phenomenon of the heat exchange medium temperature decreasing due to convection caused by the heat exchange medium flowing out of the heat storage cavity from a single location, thus improving heating efficiency.

[0029] In some implementations, such as Figure 1 As shown, the aforementioned heat storage tank 200 is equipped with a heat storage cavity for storing the heat exchange medium, and the heat exchange tube 21 is connected to the heat storage cavity. The heat storage tank 200 is also connected to an electric heating device 22, with the heat exchange tube 21 positioned close to the heating end of the electric heating device 22. The electric heating device 22 can heat the heat exchange medium to store heat. When it is necessary to heat drinking water, the high-temperature heat exchange medium can be transported into the heat exchanger 100 to exchange heat with the drinking water, thereby heating the drinking water. This heating method allows for pre-storage of heat, has lower power consumption compared to existing instant heating methods, and is safer to use. Compared to existing water storage heaters, drinking water can be heated and used immediately, ensuring the quality of drinking water.

[0030] In some implementations, such as Figure 2 As shown, the aforementioned heat storage tank 200 is equipped with two heat exchange tubes 21, which can be selectively connected to the medium channel 11. Specifically, along the communication direction between the medium channel 11 and the heat exchange tubes 21, a valve body 500 is provided between each heat exchange tube 21 and the medium channel 11 to allow the two heat exchange tubes 21 to be selectively connected to the medium channel 11. The valve body 500 can control the on / off state between the two heat exchange tubes 21 and the medium channel 11, thereby enabling the following application methods:

[0031] First, the two valve bodies 500 can be alternately switched on and off, allowing the heat exchange medium to flow out from different parts of the heat storage tank 200. This helps the high-temperature heat exchange medium inside the heat storage tank 200 to flow out of the heat storage tank 200 more evenly, reducing the convection between the high-temperature and low-temperature heat exchange medium. This allows for greater utilization of the heat of the heat exchange medium and improves the heating efficiency of the heating device.

[0032] Secondly, both valve bodies 500 can be opened simultaneously. At this time, the heat exchange medium can be simultaneously transported into the heat exchanger 100 through the two heat exchange tubes 21, which allows the heat exchanger 100 to obtain more heat in the same time period, thereby improving the heating efficiency of drinking water.

[0033] In some embodiments, the heat exchanger 100 is provided with at least two medium channels 11, which are connected to the heat exchange tube 21. Each medium channel 11 is adjacent to and spaced apart from the water flow channel 12.

[0034] In practical applications, the two medium channels 11 are arranged adjacent to the water flow channel 12, so that when the drinking water flows through the water flow channel 12, it can absorb the heat transferred from the two medium channels 11 at the same time. Furthermore, each of the two medium channels 11 is individually connected to a heat exchange tube 21, so that both medium channels 11 can flow through the heat exchange medium at a high temperature and then transfer heat to the drinking water at the same time, thereby improving the heating efficiency of the drinking water.

[0035] Furthermore, the outlets of the two heat exchange channels can be combined into one water path through a three-way connector, and then connected to the tank 22. This design can reduce the number of interfaces on the surface of the tank 22. It is understandable that the more interfaces on the surface of the tank 22, the more detrimental it is to the sealing performance of the tank 22 itself. Therefore, the above design is beneficial to enhancing the sealing performance of the tank 22.

[0036] In other embodiments, the heat exchanger 100 has multiple water flow channels 12 and multiple medium channels 11, which are alternately arranged and spaced apart from each other. This design can significantly improve the heat exchange efficiency of the heat exchanger 100.

[0037] In some implementations, such as Figure 2As shown, along the communication direction between the medium channel 11 and the heat exchange tube 21, a circulation pump 400 is provided between each heat exchange tube 21 and the medium channel 11 to drive the heat exchange medium to circulate between the heat storage tank 200 and the heat exchanger 100. The circulation pump 400 is provided with a first gear and a second gear, and the output power of the first gear and the second gear are different. When one heat exchange tube 21 is used to transport the heat exchange medium to the heat exchanger 100 or two heat exchange tubes 21 are used to alternately transport the heat exchange medium to the heat exchanger 100, the circulation pump 400 is in the lower power first gear. When two heat exchange tubes 21 are used to transport the heat exchange medium to the heat exchanger 100 at the same time, the circulation pump 400 is in the higher power second gear. Through the above design, the high heating device can be adapted to the heating needs of various drinking waters.

[0038] In some embodiments, the heat exchanger 100 provided in this application is provided with two medium channels 11, which are located on opposite sides of the water flow channel 12. This design allows the drinking water in the water flow channel 12 to absorb heat from the medium channels 11 from both opposite sides, thus improving the heating efficiency of the drinking water.

[0039] In some implementations, such as Figure 1 As shown, the heating device provided in this application also includes an instantaneous heater 300, which is connected in series or parallel with the heat exchanger 100 along the flow direction of the drinking water. In practical applications, the temperature of the heat exchange medium in the heat storage tank 200 will decrease after prolonged use. When the temperature drops to a certain level, it will no longer be able to effectively exchange heat with the drinking water through the heat exchanger 100. At this time, the heating device can heat the drinking water through the instantaneous heater 300, thereby improving the heating efficiency of the heating device.

[0040] Furthermore, when the temperature of the heat exchange medium in the heat storage tank 200 is insufficient, the instantaneous heater 300 can supplement the heat of the drinking water heated by the heat exchanger 100, so that even if the heat of the heat exchange medium in the heat storage tank 200 is insufficient, the user can still obtain water at a higher temperature through the temperature supplementation effect of the instantaneous heater 300.

[0041] In some embodiments, the instantaneous heater 300 is optionally connected to the heat storage tank 200. With the above design, the heat exchange medium inside the heat storage tank 200 is normally heated drinking water. When the temperature of the hot water inside the heat storage tank 200 is insufficient, in addition to the electric heating element 23 inside the heat storage tank 200 heating the hot water, the instantaneous heater 300 can also be used to heat the drinking water inside the heat storage tank 200. This allows the heat storage tank 200 to store heat more quickly for supplying heat to the heat exchanger 100; the above process also improves the heating efficiency of the heating device for drinking water.

[0042] In some parts of my country, electricity prices vary throughout the day, with low electricity prices typically occurring at night when people are resting. The aforementioned heating device can store heat through the heat storage tank 200 and heat exchange medium during periods of low electricity prices, and then release the stored heat through the heat exchanger 100 to heat drinking water during periods of high electricity prices. In this way, users can save on electricity bills.

[0043] This application provides a water supply device including the aforementioned heating device. Because the heating device has multiple heat exchange tubes 21 installed on the heat storage tank 200, the heat exchanger 100 can simultaneously receive heat exchange medium from multiple heat exchange tubes 21 when exchanging heat with drinking water, thereby improving the efficiency of heat exchanger 100 in obtaining heat and thus increasing the heating efficiency of drinking water.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
