[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0033] This utility model provides a water circuit for a water dispenser, comprising:

[0034] The room temperature water circuit is connected to the water source and the water dispenser outlet at both ends, which can deliver water from the water source to the water dispenser outlet at room temperature.

[0035] The cooling water circuit is connected to the water source and the water dispenser outlet at both ends, and is equipped with a cooling device that can cool the water entering from the water source and output it to the outlet.

[0036] The electric heating water circuit is connected to a water source and a water dispenser outlet at both ends. It is equipped with a first phase change device that is connected to a refrigeration device and can absorb the heat generated by the refrigeration device to preheat the water entering from the water source. It is also equipped with an electric heating device that is located after the first phase change device and electrically connected to the first phase change device. The device can supplement the preheated water as it passes through the heating device to reach the required outlet temperature.

[0037] The electrolytic water circuit is connected to the water source at one end and to the ambient temperature water circuit, the cooling water circuit, and the electrically heated water circuit at the other end. It can electrolyze the water entering from the water source and mix the electrolyzed hydrogen into the corresponding water circuit to output bubble water.

[0038] Specifically, the water dispenser of this application is connected to two water sources at the same time. The first water source is tap water and the second water source is purified water. The purified water is stored in a water tank and the water dispenser's water circuit is connected to the water tank outlet.

[0039] Specifically, because tap water contains many impurities, purified water is used for electrolysis to avoid these impurities affecting the process. Users can choose between tap water or purified water. When a user selects sparkling water, the water dispenser will automatically select purified water for electrolysis.

[0040] Specifically, since tap water contains a large number of bacteria that have not been sterilized, this application sets up a high-temperature boiling water circuit. The high-temperature boiling water circuit is connected to the electric heating water circuit and its two ends are respectively connected to the front and rear positions of the heating device. When the incoming water is tap water, it can drive the tap water through the electric heating device multiple times to boil the tap water.

[0041] Preferably, this application also includes an energy-saving heating water circuit. One end of the energy-saving heating water circuit is connected to a water source, and the other end passes through an area of ​​the electric heating water circuit where the first phase change device is installed and a portion of the high-temperature boiling water circuit, before connecting to the water outlet of the water dispenser. Specifically, the energy-saving heating water circuit also includes a second phase change device. During the boiling process of tap water in the high-temperature boiling water circuit, the heated tap water flows through the second phase change device multiple times. At this time, the second phase change device can absorb heat from the tap water, and the high-temperature boiling water circuit can charge the second phase change device.

[0042] Specifically, both the first and second phase change devices are made of phase change heat storage materials.

[0043] Specifically, the functions and principles of the various waterways mentioned above will be introduced in the following preliminary manner:

[0044] Normal temperature water circuit: The water source is directly discharged. Although the water passes through the electric heating device when it is discharged, the electric heating device is not activated at this time. Therefore, the water output is normal temperature water.

[0045] Cooling water circuit: The cooling unit is a cold water tank. The water source is cooled by the cold water tank, and then passes through an electric heating device at the end without heating it, and outputs cold water.

[0046] Electric heating water circuit: used for conventional heating. The water source passes through the first phase change device. If the first phase change device has heat energy, it can slightly heat the flowing water. Specifically, a temperature sensor is installed in the first phase change device. The temperature data is used to control the heating power of the electric heating device at the back. When the first phase change device heats the water to a certain temperature, the power of the electric heating device can be reduced accordingly, which can save more electricity.

[0047] Energy-saving heating water circuit: The water source passes through two phase change devices. This water circuit is used when the second phase change device has heat energy. The chip inside the water dispenser determines its own temperature by calculating the energy absorption time of the second phase change device (the circulation time of water in the high-temperature boiling water circuit). This water circuit is mainly used for small-scale heating (preset temperature threshold, less than 100 degrees Celsius). A temperature sensor is installed at the water outlet of the water dispenser. When the temperature sensor detects that the water temperature deviates significantly from the user's required temperature, it automatically switches to the electric heating water circuit.

[0048] Electrolysis water circuit: It is equipped with an alkaline water tank, a gas tank, and a pressurization device. Pure water enters the electrolysis device, and the alkaline water containing hydroxide ions generated is stored in the alkaline water tank. The generated oxygen is directly discharged to the water outlet of the water dispenser. The generated hydrogen is stored in the gas tank using the pressurization device. When the user selects sparkling water, the pressurization device adds hydrogen to the water. The water stored in the alkaline water tank can be used as a water source and enters various water circuits.

[0049] High-temperature boiling water circuit: It is equipped with an external hot water tank. The water in the hot water tank enters the electric heating device, is heated, and then returns to the hot water tank. After multiple cycles, the temperature sensor in the hot water tank detects the boiling temperature (100 degrees Celsius) and outputs the temperature. During the water circulation process, the second phase change device is located in the high-temperature boiling water circuit and absorbs heat energy. The high-temperature boiling water circuit can not only heat the water in the hot water tank, but also charge the second phase change device.

[0050] Specifically, the various waterways in this application are all composed of multiple interconnected pipes, and some pipes are shared between different waterways.

[0051] The following is a detailed description of the connections between pipes in various water systems:

A hot water tank for storing hot water is provided on the tenth pipe ⑩.

[0056] The energy-saving heating water circuit includes: the sixth pipe ⑥, the seventh pipe ⑦, the fourth pipe ④, the eighth pipe ⑧ connected to the fourth pipe ④, and the ninth pipe ⑨ connected to the eighth pipe ⑧. The other end of the ninth pipe ⑨ is connected to the fifth pipe ⑤. The second phase change device is installed on the ninth pipe ⑨.

[0057] The water electrolysis circuit includes: the sixth pipe ⑥, and the eleventh pipe connected to the sixth pipe ⑥. Installed in the eleventh pipeline An electrolysis device that electrolyzes the incoming water; an alkaline water tank connected to the electrolysis device for storing the alkaline water produced by the electrolysis; and a twelfth pipe connected at both ends to the alkaline water tank and the water source, respectively. The device includes a gas tank connected to the electrolysis unit for storing hydrogen produced by electrolysis, a mixing device connected at both ends to the gas tank and the fourth pipe ④ for pressurizing the hydrogen into the flow through the fourth pipe ④, and a thirteenth pipe connected at both ends to the electrolysis unit and the fifth pipe ⑤ for discharging oxygen produced during the electrolysis of water.

[0058] Specifically, the aforementioned water circuits are equipped with various control valves and water pumps to control the flow of water into each water circuit.

[0059] Specifically, control valves ah are installed between the tap water source, water tank, and various pipes. Control valves a, c, e, f, g, and h are three-way valves, and control valves b and d are four-way valves. The chip of the water dispenser controls the opening or closing of each control valve corresponding to each valve port to control the connection of each corresponding pipe, so that the corresponding water path is open or closed. Specifically, water pumps (1)-(3) are also installed to drive water from the water source side to the corresponding water path and output to the water outlet of the water dispenser. Specifically, water pump (1) is used to drive the water flow of the normal temperature water path, the cooling water path, the electric heating water path, and the energy-saving heating water path to flow towards the water outlet of the water dispenser; water pump (2) is used to drive the water flow to circulate in the high temperature boiling water path for boiling; water pump (3) is used to drive the water flow into the electrolysis device for electrolysis; and water pump (4) is used to drive the water flow from the alkaline water tank to the water source. Specifically, the starting and stopping of each water pump are coordinated. For example, when water needs to be boiled at high temperature, water pump (1) stops, the water dispenser does not dispense water, and water pump (2) starts to drive the water flow to circulate continuously in the high-temperature boiling water circuit.

[0060] Specifically, this application provides a fourteenth conduit. and the fifteenth pipeline Connect the tap water source and the purified water tank respectively. Specifically, control the water valve h (three-way valve) and the fourteenth pipe. When the user needs alkaline water, the valve port connected to the tap water source (h) is closed, and the other valve ports are opened. The water pump (4) starts and drives the alkaline water in the alkaline water tank to be output to the fourteenth pipeline. Then it flows backward into various waterways to exit.

[0061] Specifically, the gas tank is connected to the sixteenth pipeline. Sixteenth Pipeline The mixing device is connected to the control water valve d, which is connected to multiple pipes. When the valve port connected to the mixing device and the valve port of the pipe that needs hydrogen are opened, the mixing device can mix hydrogen into the water flow in the corresponding pipe.

[0062] Specifically, the following are the water outlet control methods for water dispensers, including the following steps:

[0063] Step 1: Determine if the incoming water is purified water. If yes, proceed to Step 2; otherwise, determine if it is tap water and proceed to Step 3.

[0064] Step 2 is: determine whether to enter electrolysis mode; if yes, proceed to the water electrolysis circuit; if not, proceed to step 3; where...

[0065] Step 3 is: determine if cooling is needed. If yes, then open the cooling water circuit; otherwise, proceed to step 4.

[0066] Step 4 is: determine if heating is needed. If yes, proceed to steps 5 and 6 simultaneously; otherwise, the room temperature water path remains open.

[0067] Step 5 is: determine whether the temperature exceeds the predetermined temperature threshold. If so, take the judgment result of step 1. If the judgment result is pure water, the electric heating water circuit is open. If the judgment result is tap water, the electric heating water circuit and the high temperature boiling water circuit are connected. After the high temperature boiling water circuit determines that the water has reached the boiling temperature, the high temperature boiling water circuit is closed and the electric heating water circuit is open.

[0068] Step 6 is: Determine whether the water has been heated to the predetermined temperature threshold. If yes, then the power-saving heating water circuit is open; otherwise, the electric heating water circuit is open.
