[0033] In the embodiment of the present application, the drinking water in the storage space always maintains a preset water level. Specifically, the hot water tank is always kept full of water. While the drinking water at the bottom is replenished into the hot water tank, the hot water at the top of the hot water tank is pushed out of the water tank shell and enters the water outlet pipe 5.

[0034] In the embodiment of the present application, the first heating device 2 and the second heating device 3 also include an interface part, which is integrally arranged with the heating part, and the interface part is fixedly connected to the water tank shell. The interface part is used to connect with other devices, including but not limited to a power supply device and a control device.

[0035] In a specific embodiment of the present application, the water purifier includes a water purifier controller, which is communicated with the first heating device 2, the second heating device 3 and the quick heating device 6 respectively. The water purifier controller is used to control the first heating device 2 and the second heating device 3 to heat the drinking water in the storage space, and is used to control the quick heating device 6 to auxiliary heat the drinking water at the water outlet so that the temperature of the outflowing hot water reaches a preset temperature; the preset temperature can be 90°C or 95°C.

[0036] In an embodiment of the present application, a quick heating device 6 is provided between the water outlet pipe 5 of the hot water tank and the hot water taking pipe of the water purifier, so that the hot water flows out of the hot water taking port after passing through the quick heating device 6, and then the quick heating device 6 performs auxiliary heating on the hot water to avoid insufficient temperature of the hot water or to avoid long waiting due to insufficient hot water, thereby improving the user's water taking comfort.

[0040] In another specific embodiment of the present application, the quick-heating heating tube 62 includes a spiral portion 621 and a straight portion 622 , the spiral portion 621 is arranged on the outside of the water outlet pipe 5 , and the straight portion 622 is arranged on the inside of the water outlet pipe 5 .

[0041] In another specific embodiment of the present application, by setting the straight portion 622 on the inner side of the water outlet pipe and setting the spiral portion 621 on the outer side of the water outlet pipe, the contact area of ​​the heating pipe is reduced, thereby avoiding safety problems caused by the heating pipe factor and improving the safety of the water purifier.

[0042] In an embodiment of the present application, the water purifier further includes a plurality of temperature sensors arranged sequentially from the top of the storage space to the bottom of the storage space.

[0043] In the embodiment of the present application, since the water in the hot water tank is always full, multiple temperature sensors are arranged in sequence from top to bottom to detect the temperatures at different positions, so as to control the heating of the hot water tank based on the detected temperature results, so as to avoid long waiting time caused by insufficient hot water supply, or avoid energy waste caused by excessive hot water supply.

[0044] refer to Figure 4 In an embodiment of the present application, multiple temperature sensors include a top temperature sensor 7, a middle temperature sensor 8 and a bottom temperature sensor 9; the top temperature sensor 7 is close to the top of the storage space, and the bottom temperature sensor 9 is close to the bottom of the storage space; the middle temperature sensor 8 is arranged between the top temperature sensor 7 and the bottom temperature sensor 9.

[0045] In a specific embodiment of the present application, when there are too many people resulting in insufficient hot water supply, the bottom temperature sensor 9 can be used as a judgment condition for whether the drinking water in the hot water tank is boiled; when hot water is supplied normally, the middle temperature sensor 8 can be used as a judgment condition for whether the drinking water in the hot water tank is boiled; when there are too few people resulting in excessive hot water supply, the bottom temperature sensor 9 can be used as a judgment condition for whether the drinking water in the hot water tank is boiled.

[0046] In an embodiment of the present application, different temperature sensors are used in different situations to monitor whether the drinking water in the hot water tank is boiling, so that the heating of the hot water tank can be matched with the actual number of people taking water; for example: when there are many people, the first heating tube, the second heating tube and the quick heating device 6 are turned on at the same time; when there are few people, only the quick heating device 6 is turned on, etc.; thereby improving the matching of the water purifier with the actual scene.

[0047] In the embodiment of the present application, an outlet temperature sensor 10 is provided on the water outlet pipe 5, and the outflowing drinking water flows through the outlet temperature sensor 10 and the quick heating device 6 in sequence.

[0048] In a specific embodiment of the present application, the water purifier controller controls the opening and closing of the quick heating device 6 based on the detection result of the outlet temperature; specifically, the quick heating device 6 is started when the temperature of the water outlet is lower than the preset temperature, and the quick heating device 6 is turned off when the temperature of the water outlet is greater than or equal to the preset temperature.

[0049] In a preferred embodiment of the present application, the working power of the rapid heating device 6 can also be determined based on the temperature difference between the temperature value detected by the outlet temperature sensor 10 and the preset temperature.

[0050] In the embodiment of the present application, the hot water tank further includes a safety valve 11 for discharging gas, and the safety valve 11 is arranged at the top of the storage space.

[0051] In the embodiment of the present application, since the drinking water in the hot water tank is always full of water, water vapor will be generated in the process of heating the drinking water, and the volume change in the hot water tank is small, the accumulation of water vapor will cause the air pressure in the hot water tank to be too high. A safety valve 11 is provided to allow excess water vapor to be discharged from the hot water tank, thereby ensuring the stability of the air pressure in the hot water tank and improving the safety of the water purifier.

[0052] In the embodiment of the present application, the working power of the first heating device 2 is less than the working power of the second heating device 3 .

[0053] In the embodiment of the present application, by setting the working power of the first heating device 2 to be smaller than the working power of the second heating device 3, the operation of the first heating device 2 or the second heating device 3 can be adapted to different working scenarios; specifically, when there are many people, the second heating device 3 with higher power is turned on to heat the drinking water in the hot water tank, and when the number of people is normal, the first heating device 2 with lower power is turned on to heat the drinking water in the hot water tank; by setting the working power of the first heating device 2 to be smaller than the working power of the second heating device 3, the matching of the water purifier with the actual scenario is improved, while the heating energy consumption of the hot water tank is reduced.

[0054] In the embodiment of the present application, the hot water tank further comprises a heat filling bracket 12, the heat filling bracket 12 is fixedly connected to the water tank shell 1, and the heat filling bracket 12 matches the mounting structure on the water purifier.

[0055] In the embodiment of the present application, the hot filling bracket 12 is provided to improve the assembly stability of the hot water tank and the water purifier, thereby improving the reliability of the water purifier.

[0056] The working principle of the hot water tank in the embodiment of the present application is described below:

[0057] Under normal working conditions, the quick heating device 6 may be started or not started, the first heating device 2 and / or the second heating device 3 heat the drinking water in the storage space, and the quick heating device 6 may be started to perform auxiliary heating on the outflowing drinking water;

[0058] When the temperature of the drinking water in the storage space is insufficient, the quick heating device 6 is started, and the first heating device 2 and / or the second heating device 3 may be started or not. The quick heating device 6 heats the outflowing drinking water so that the temperature of the outflowing hot water reaches a preset temperature, and the first heating device 2 and / or the second heating device 3 may be started to assist in heating the drinking water in the storage space.

[0059] In addition, the working status of the first heating device 2 and the second heating device 3 can also be determined based on the number of people using water; specifically, when there are many people, the second heating device 3 with a large working power can be started first, so that the drinking water in the hot water tank can be heated quickly, and when the overall working power permits, the first heating device 2 and the second heating device 3 can be started at the same time; when there are fewer people, only the first heating device 2 with a small working power can be started, and the energy-saving mode can also be entered, in which neither the first heating device 2 nor the second heating device 3 is started, and only heating is performed by the quick heating device 6.

[0060] The hot water tank in the embodiment of the present application has the following beneficial effects:

[0061] By arranging a quick heating device 6 between the water outlet pipe 5 of the hot water tank and the hot water taking pipe of the water purifier, the hot water can flow out of the hot water taking port after passing through the quick heating device 6, and then the quick heating device 6 can assist in heating the hot water to avoid insufficient temperature of the hot water or to avoid long waiting due to insufficient hot water, thereby improving the user's water taking comfort.
