[0029] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, the terms "first", "second", "third", "fourth", "fifth", "sixth", and "seventh" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0030] Based on the problem pointed out in the background art that the water output of existing boiled water dispensers is low, resulting in users being unable to get a large amount of water, the present invention uses a water storage tank to pre-store cooled boiled water, and directly outputs a large amount of boiled water through a water pump to meet users' large water needs, thereby improving the user experience.

[0031] Specifically, if Figure 1 and Figure 2As shown, the boiled water making system of the present invention includes a heat exchanger 1, a filtering device, a first heating body 2, a water storage tank 3 and a water outlet formed on a faucet 6. More specifically, the heat exchanger 1 includes a hot water flow channel and a cold water flow channel for exchanging heat with the hot water flow channel. The cold water inlet 11 and the cold water outlet 12 of the heat exchanger 1 are respectively located at the two ends of the cold water flow channel, and the hot water inlet 13 and the warm water outlet 14 of the heat exchanger 1 are respectively located at the two ends of the hot water flow channel. The water outlet end of the filter device is connected to the cold water inlet 11 of the heat exchanger 1; the two ends of the first heating body 2 are respectively connected to the cold water outlet 12 and the hot water inlet 13 of the heat exchanger 1, that is, the inlet of the first heating body 2 is connected to the cold water outlet 12 of the heat exchanger 1, and the outlet of the first heating body 2 is connected to the hot water inlet 13 of the heat exchanger 1; the water storage tank 3 has a chamber, and the chamber of the water storage tank 3 is connected to the warm water outlet 14 of the heat exchanger 1; the chamber of the water storage tank 3 is connected to the water outlet; wherein, a water pump 4 is provided between the chamber of the water storage tank 3 and the water outlet of the faucet 6. In addition, a switch valve 91 is provided between the chamber of the water storage tank 3 and the warm water outlet 14 of the heat exchanger 1 , and a one-way check valve is provided between the inlet of the first heating body 2 and the cold water outlet 12 of the heat exchanger 1 .

[0032] With such a setting, the pure water filtered by the filter device is heated to a boiling state when it flows through the first heating body 2. The boiled water flows through the hot water flow channel of the heat exchanger 1 and exchanges heat with the cold water flow channel to cool down to form boiled water. The switch valve 91 is opened to directly transport the boiled water flowing out of the heat exchanger 1 into the chamber of the water storage tank 3 and fill the chamber. When the user takes water, the boiled water in the water storage tank 3 is quickly output to the water outlet of the faucet 6 through the water pump 4. In other words, the water flow rate of the water outlet of the faucet 6 is mainly determined by the water pumping flow rate of the water pump 4, thereby meeting the user's large water needs and saving the user's water collection time.

[0033] It should be noted that, according to actual applications, those skilled in the art may set the water storage liner 3 to be a conventional heat-insulating liner with a heat-insulating structure, for example, a foam insulation layer or a vacuum insulation layer may be provided on the outside of the water storage liner 3, or a heat-insulating heat liner with a heating function may be provided inside the water storage liner 3, for example, a heating pipe may be provided, etc. Such flexible adjustment and change of the specific function and structure of the water storage liner 3 does not deviate from the basic principle and scope of the present invention, and should be limited within the scope of protection of the present invention.

[0034] Preferably, if Figure 1 and Figure 2 As shown, the water storage container 3 of the present invention further includes a second heating body 32 located at the bottom of the chamber and a water level probe 33 located at the top of the chamber.

[0035] For example, Figure 1 and Figure 2As shown, the housing 31 of the present invention, which forms the chamber of the water storage liner 3, is provided with an inlet 311 connected to the warm water outlet 14 of the heat exchanger 1 and an outlet of the water storage liner 3 (not shown). The inlet 311 of the water storage liner 3 and the water level probe 33 are located at the top of the chamber, while the outlet of the water storage liner 3 and the second heating element 32 are both located at the bottom of the chamber of the housing 31. A water pump 4 is fixedly mounted at the bottom of the housing 31, and the inlet of the water pump 4 (not shown) is connected to the outlet of the water storage liner 3.

[0036] It should be noted that the boiled water making system is also provided with a controller, wherein the switch valve 91, the water level probe 33 and the second heating body 32 are all communicatively connected to the controller.

[0037] When the boiled water making system is making water, the water flowing out of the warm water outlet 14 of the heat exchanger 1 enters the chamber of the water storage tank 3 for storage. When the water level reaches the position of the top water level probe 33, the water level probe 33 is connected to the controller provided in the boiled water making system for communication. The controller receives the signal from the water level probe 33 to close the switch valve 91 and stop the system from making water, thereby ensuring that the water in the water storage tank 3 is in a sufficient state, while also ensuring the safety of the use of the water storage tank.

[0038] When the water temperature in the water storage tank 3 is too low, the second heating body 32 provided at the bottom of the water storage tank 3 is used to keep the boiled water in the water storage tank 3 warm and heat it, thereby ensuring that the water temperature of the boiled water is maintained within an appropriate temperature range, thereby meeting the user's demand for boiled water at different temperatures.

[0039] Preferably, if Figure 1 and Figure 2 As shown, the boiled water making system also includes a regulating valve 5, which includes a first interface 51, a second interface 52 and a third interface 53; the first interface 51 is connected to the outlet of the first heating body 2, the second interface 52 is connected to the outlet 41 of the water pump 4, and the third interface 53 is connected to the water outlet on the faucet 6.

[0040] When the user closes the regulating valve 5 and opens the faucet 6 to take water, the boiled water making system can output a large amount of boiled water in the water storage tank 3 to the faucet 6 by simply turning on the water pump 4.

[0041] When a user opens the regulating valve 5 and taps 6 to draw water, the boiled water system activates the water production mode and activates the pump 4. The pump 4's outlet 41 delivers the water from the water tank 3 to the tap 6 via a first connecting pipe. The pump 4's outlet 41 also delivers the water from the water tank 3 to the second port 52 of the regulating valve 5 via a second connecting pipe. Hot water from the first heating element 2 and water from the water tank 3, after temperature adjustment by the regulating valve 5, flow through the third port 53 to the tap 6. This delivers boiled water of varying temperatures from the tap 6, increasing the output of boiled water from the tap 6.

[0042] In a first preferred embodiment, if Figure 1 As shown, the boiled water making system of the present invention further includes a first flow control module 81 , which is arranged between the water outlet of the filter device and the cold water inlet 11 .

[0043] For example, Figure 1 As shown, in this preferred embodiment, the first flow control module 81 is a flow control pump, and the filtering device includes a reverse osmosis filter element 71. The wastewater end of the reverse osmosis filter element 71 is provided with a wastewater solenoid valve 93, and the wastewater is discharged through the wastewater solenoid valve 93. The inlet of the flow control pump is connected to the pure water port of the reverse osmosis filter element 71, and the outlet of the flow control pump is connected to the cold water inlet 11 of the heat exchanger 1. A high-pressure switch valve 92 is also provided between the outlet of the flow control pump and the cold water inlet 11 of the heat exchanger 1. Through such a setting, the flow control pump can regulate the water inlet flow rate entering the cold water channel of the heat exchanger 1, avoid excessive water inlet flow causing the heat exchange channel in the heat exchanger 1 to be subjected to a high water inlet pressure, and ensure the safety of the heat exchanger 1.

[0044] In a second preferred embodiment, Figure 2 As shown, the boiled water making system of the present invention also includes a second flow control module 82, wherein the filtration device includes a booster pump 72 connected to the reverse osmosis filter element 71, and the outlet of the booster pump 72 is connected to the inlet of the reverse osmosis filter element 71. The second flow control module 82 includes a fourth interface 821, a fifth interface 822, a sixth interface 823 and a seventh interface 824. The fourth interface 821 is connected to the water source, the fifth interface 822 is connected to the inlet of the booster pump 72, the sixth interface 823 is connected to the pure water outlet of the reverse osmosis filter element 71, and the seventh interface 824 is connected to the water inlet end of the first flow control module 81.

[0045] When the water source is connected to the fourth interface 821 of the second flow control module 82, the drive motor built into the second flow control module 82 can steadily flow the water out of the fifth interface 822. The water flows in turn through the booster pump 72 and enters the reverse osmosis filter element 71 for filtration. The filtered pure water flows through the sixth interface 823 into the diverter valve built into the second flow control module 82. The diverter valve diverts some of the pure water to the downstream output flow control pump through the first interface, and the other part of the pure water is unidirectionally returned to the fifth interface 822 for reuse. A wastewater solenoid valve 93 is installed at the wastewater end of the reverse osmosis filter element 71, and the wastewater is discharged through the wastewater solenoid valve 93.

[0046] It should be noted that the present invention does not impose any restrictions on the specific structure of the above-mentioned second flow control module 82. According to actual applications, those skilled in the art may also use a combination of a flow control pump and a flow regulating valve to achieve the above-mentioned functions. For example, a flow control pump is used to implement the functions of the fourth interface 821 and the fifth interface 822, and a flow regulating valve is used to implement the functions of the sixth interface 823 and the seventh interface 824, wherein the sixth interface 823 can be unidirectionally connected to the fifth interface 822. Such flexible adjustment and change of the specific functional structure of the second flow control module 82 does not deviate from the basic principles and scope of the present invention, and should be limited within the scope of protection of the present invention.

[0047] Through such a setting, with the help of the second flow control module 82, the water source can be stably input into the reverse osmosis filter element 71. At the same time, the second flow control module 82 realizes the diversion of pure water, so that the pure water flow of the reverse osmosis filter element 71 matches the water inlet flow of the downstream heat exchanger 1, thereby achieving the stability of the water flow of the boiled water production system.

[0048] It should be noted that the present invention does not impose any restrictions on the specific structure of the above-mentioned heat exchanger 1. As long as the heat exchanger 1 can exchange heat and cool the water flowing through it, the heat exchanger 1 can adopt a spiral tube heat exchange structure, or the heat exchanger 1 can also adopt a plate-type stacked heat exchange structure, etc. Such flexible adjustment and change of the specific heat exchange structure of the heat exchanger 1 does not deviate from the basic principles and scope of the present invention, and should be limited within the scope of protection of the present invention.

[0049] Furthermore, the present invention does not impose any limitations on the specific structures of the first heating element 2 and the second heating element 32. As long as the first heating element 2 is capable of heating and boiling the water flowing through it, and the second heating element 32 is capable of heating and maintaining the water in the water storage tank 3, those skilled in the art can customize the structure of the heating elements according to actual needs. For example, the first heating element 2 can be configured as a tubular structure with an electric heating wire, or the first heating element 2 or the second heating element 32 can be configured as an electromagnetic heating device, etc. Such flexible adjustments and modifications do not deviate from the basic principles and scope of the present invention and are intended to be within the scope of protection of the present invention.

[0050] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
