[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1 , Figure 2 The heating device shown includes a heat exchanger 100 and at least two heat storage tanks 200. The heat exchanger 100 is provided with a heating channel 11 and a water flow channel 12, which are isolated from each other. The heating channel 11 is used for the flow of liquid inside the heat storage tank 200, and the water flow channel 12 is used for the flow of drinking water. In actual use, the heating channel 11 and the water flow channel 12 are separated by a partition, so that the liquid inside the heating channel 11 can exchange heat with the liquid inside the water flow channel 12 through the partition, thereby heating the drinking water.

[0030] Each heat storage tank 200 is provided with a heat storage cavity, a liquid inlet 21 and a liquid outlet 22. The heat storage cavity is used to store liquid, and the liquid inlet 21 and the liquid outlet 22 are used to allow the liquid inside the heat storage cavity to flow into or out of the heat storage cavity, respectively. The liquid inlet 21 and the liquid outlet 22 are both connected to the heat storage cavity. At least two heat storage tanks 200 are connected to the heating channel 11 of the same heat exchanger 100 through the liquid inlet 21 and the liquid outlet 22. Multiple heat storage tanks 200 can be connected in series or in parallel.

[0031] If each heat storage tank 200 is connected in series, it can be understood that each heat storage tank 200 is provided with a heating device inside, and the simultaneous operation of multiple heating devices is beneficial to the rapid heating of the liquid inside the heat storage tank 200, and accordingly improves the heating efficiency of the heat exchanger 100 on the drinking water.

[0032] If each heat storage tank 200 is connected in parallel, that is, each heat storage tank 200 can be individually connected to the heat exchange channel of the heat exchanger 100, it can be understood that each heat storage tank 200 can alternately supply heat to the heat exchanger 100. In actual practice, if the temperature of the liquid inside one heat storage tank 200 is not enough, another heat storage tank 200 can be used to supply heat to the heat exchanger 100. Overall, it also improves the heating efficiency of the heat exchanger 100 on the drinking water.

[0033] In some embodiments, at least two of the heat storage tanks 200 are connected in parallel and can be selectively connected to the heat exchange channel, and a water pump is provided between each heat storage tank 200 and the heat exchanger 100. Specifically, the heating device is connected in parallel with two heat storage tanks 200, both of which are connected to the heat exchange channel. The two heat storage tanks 200 can supply heat to the heat exchanger 100 through the respective water pumps, or they can supply heat to the heat exchanger 100 at the same time. If the two heat storage tanks 200 supply heat to the heat exchanger 100 individually, one heat storage tank 200 supplies heat while the other heat storage tank 200 stores heat for alternating supply to the heat exchanger 100. If the two heat storage tanks 200 supply heat to the heat exchanger 100 at the same time, the heat exchanger 100 can obtain more heat in the same time. Both of the above connection methods can improve the heating efficiency of the heat exchanger 100 on the drinking water.

[0034] In other embodiments, at least two of the heat storage tanks 200 are connected in series and connected to the heat exchange channel, and a water pump is provided between the heat storage tank 200 and the heat exchanger 100. Specifically, the heating device is connected in series with two heat storage tanks 200, which are connected in series to supply heat to the heat exchanger 100. This can also allow the heat exchanger 100 to obtain heat from both heat storage tanks 200 during the heating process, thereby improving the heating efficiency on the drinking water.

[0035] In some embodiments, the above-mentioned heat supply channel 11 includes a first channel and a second channel, which are spaced apart and not connected. The first channel and the second channel are each connected to a separate heat storage tank 200. Through the above design, multiple heat storage tanks 200 can be connected to supply heat to the heat exchanger 100 at the same time when heating the drinking water, and the heat exchanger 100 can also heat the drinking water through the first channel and the second channel at the same time, which is beneficial to improving the heating efficiency of the drinking water.

[0036] Further, since the first channel and the second channel are respectively connected with the separate heat storage tanks 200, the first channel and the second channel can respectively perform high-temperature heat exchange and low-temperature heat exchange, and correspondingly, the temperatures of the liquids inside the corresponding heat storage tanks 200 of the first channel and the second channel are different. Specifically, the first channel is used for low-temperature heat exchange, and in actual use, the liquid flowing inside the first channel has a relatively low temperature, and the drinking water flowing through the heat exchanger 100 can be heated relatively slowly through the first channel, which is suitable for obtaining drinking water with a relatively low temperature; the second channel is used for high-temperature heat exchange, and in actual use, the liquid flowing inside the second channel has a relatively high temperature, and the drinking water flowing through the heat exchanger 100 can be heated relatively quickly through the second channel, which is suitable for obtaining drinking water with a relatively high temperature.

[0037] In addition to the above effects, since the first channel and the second channel are arranged in a spaced manner and are respectively connected with different heat storage tanks 200, it is equivalent that the liquids flowing inside the first channel and the second channel are in a completely separated state and can not interfere with each other.

[0038] On the basis of the above structure, the heating device further comprises a heat exchange medium, which is contained inside the heat storage tank 200, and the boiling points of the heat exchange media arranged inside different heat storage tanks 200 are the same or different. According to the above description, since the liquids flowing inside the first channel and the second channel are in a completely separated state, the types of the heat exchange media contained inside each heat storage tank 200 can also be different, and since the boiling points of different heat exchange media are different, the following applications can be produced.

[0039] When high-temperature water needs to be obtained in a short time, the heat storage tank 200 can contain a liquid (for example, oil) with a boiling point higher than water, and when used, the heat exchanger 100 can be heated by the liquid with a boiling point higher than water, so that the heat exchanger 100 can obtain more heat in a short time, and then the drinking water can be quickly heated to a relatively high temperature.

[0040] In some embodiments, the water flow channel 12 comprises a first flow channel and a second flow channel, the first flow channel is arranged in a spaced manner with the first channel, and the second flow channel is arranged in a spaced manner with the second channel. In actual application, by using the above-mentioned manner, the user can simultaneously discharge water through the first flow channel and the second flow channel, and thus the efficiency of hot water discharge can be increased, and more hot water can be obtained in the same time.

[0041] In some embodiments, the liquid inlet 21 of the heat storage tank 200 is connected to one end of the heat supply channel 11 of the heat exchanger 100 through a pipeline, and the liquid outlet 22 of the heat storage tank 200 is in communication with the other end of the heat supply channel 11 of the heat exchanger 100; one end of the water flow channel 12 is used to connect to a drinking water pipe, and the other end is used to connect to a faucet W. In actual application, drinking water is connected to the inside of the water flow channel 12 of the heat exchanger 100 through a pipeline, and the liquid stored in the heat storage tank 200 is heated by the heating device arranged in the heat storage tank 200 and then flows out of the liquid outlet 22 under the action of the water pump, and then flows into the heat supply channel 11 of the heat exchanger 100 through a pipeline to supply heat to the heat exchanger 100. In this way, the drinking water in the water flow channel 12 can absorb heat from the heat supply channel 11 to be heated, and the liquid in the heat supply channel 11 is cooled and then flows out of the liquid outlet 22 and flows into the heat storage tank 200 through a pipeline to circulate and supply heat. The heat storage tank 200 can store heat in advance through the liquid stored in it, and then heat the drinking water through the heat exchanger 100; it can realize instant heating and use of drinking water, without the need to store heated drinking water, ensuring the quality of the drinking water, and without the need to configure a heating device with high power.

[0042] In some embodiments, as shown in Figure 2 , Figure 3 The heating device further comprises a switching mechanism 300 arranged between the plurality of heat storage tanks 200, and the switching mechanism 300 can be switched from a series state to a parallel state. When the switching mechanism 300 is in the series state, the plurality of heat storage tanks are connected in series, and when the switching mechanism 300 is in the parallel state, the plurality of heat storage tanks are connected in parallel.

[0043] Specifically, as shown in Figure 3 The heating device comprises two heat storage tanks 200, namely an A tank A and a B tank B, the switching mechanism 300 comprises a first shunt valve 31 and a second shunt valve 32, the first shunt valve 31 is arranged between the A tank A and the heat exchanger 100, the second shunt valve 32 is arranged between the B tank B and the heat exchanger 100, and the first shunt valve 31 and the second shunt valve 32 can selectively communicate with the heat exchanger 100 or communicate with each other.

[0044] When the two heat storage tanks 200 are in parallel, the first and second shunt valves 31 and 32 are disconnected from each other and are both in communication with the heat exchanger 100, and the liquid inlet 21 and the liquid outlet 22 of the two heat storage tanks 200 are in communication with the heat supply channel 11. In the parallel state, the heat exchange medium in the two heat storage tanks 200 is not in communication, and in actual application, the user uses the heat storage tank A 200 to supply heat to the heat exchanger 100 when discharging water for the first time, and the liquid in the heat exchanger 100 is still in a high-temperature state. After the first time of discharging water, the heat storage tank A 200 starts to heat the heat exchange medium inside, and when the user discharges water for the second time in a short time, the heat storage tank B 200 can be switched to supply heat to the heat exchanger 100. In this way, the user can get water with a higher temperature twice. After the two heat storage tanks 200 are connected in parallel, the two heat storage tanks 200 can alternately supply heat. It can be understood that this method is suitable for discharging water multiple times in a short time.

[0045] When the two heat storage tanks 200 are in series, the first and second shunt valves 31 and 32 are connected and are both disconnected from the heat exchanger 100, the liquid outlet 22 of the heat storage tank A A is in communication with the liquid inlet 21 of the heat storage tank B B, and the liquid inlet 21 of the heat storage tank A A and the liquid outlet 22 of the heat storage tank B B are in communication with the heat exchange channel 11. The heat exchanger 100 can simultaneously obtain the heat of the heat exchange medium inside the two heat storage tanks 200 to heat the drinking water. It can be understood that the above-mentioned situation is suitable for discharging water for a long time.

[0046] In summary, the above-mentioned switching mechanism 300 can make the heating device suitable for different actual needs, thereby meeting various use requirements.

[0047] The application provides a water supply device, which adopts the above-mentioned heating device, thereby improving the heating efficiency of the water supply device on drinking water; and without heating and storing the drinking water in advance, the drinking water can be heated in real time by the heat exchanger 100 when hot water is discharged, that is, the drinking water can be used immediately after being heated, thereby avoiding the problem of affecting the quality of the drinking water due to long storage time.

[0048] In some embodiments, as shown in Figure 1 , Figure 2 The water supply device further comprises a heat supplement device S connected in series with the heating device. In actual use, the heat supplement device S can further heat the water heated by the heat exchanger 100, thereby facilitating obtaining water with a higher temperature and more.
