DETAILED DESCRIPTION

[0016] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0017] The present invention provides a water circuit for a water dispenser, comprising: The normal temperature water channel has two ends connected to the water source and the water outlet of the water dispenser, respectively, and can transport the water entering from the water source to the water outlet of the water dispenser at normal temperature; The cooling water circuit has two ends connected to the water source and the water outlet of the water dispenser, and is provided with a cooling device that can cool the water entering from the water source and output it to the water outlet; The electric heating water circuit has two ends connected to the water source and the water outlet of the water dispenser, respectively, and is provided with a first phase-changing device interconnected with the refrigeration device and capable of absorbing the heat generated by the refrigeration device during refrigeration to preheat the water entering from the water source, and an electric heating device located after the first phase-changing device and electrically connected to the first phase-changing device, capable of supplementarily heating the preheated water when the preheated water passes through it to reach the required outlet temperature; The electrolysis water circuit is connected to the water source at one end and to the normal temperature water circuit, the cooling water circuit and the electric heating 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.

[0018] Specifically, the water circuit of the water dispenser of the present 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 circuit of the water dispenser is connected to the water outlet of the water tank.

[0019] Specifically, since there are many impurities in tap water, in order to avoid the impurities affecting the electrolysis process, pure water is used for electrolysis. Users can choose tap water or pure water for water output. When the user chooses sparkling water, the water path of the water dispenser will automatically select pure water for electrolysis.

[0020] Specifically, since there are many bacteria in tap water that have not been sterilized, the present application sets up a high-temperature boiling water circuit, which is connected to the electric heating water circuit and has both ends connected to the front and rear positions of the heating device respectively. When the incoming water is tap water, it can drive the tap water to pass through the electric heating device multiple times to boil the tap water.

[0021] Preferably, the present application also provides an energy-saving heating water circuit, one end of which is connected to a water source, and the other end passes through an area of ​​the electric heating water circuit where a first phase change device is provided and a part of the high-temperature boiling water circuit, and then is connected to the water outlet of the water dispenser. Specifically, a second phase change device is also provided on the energy-saving heating water circuit, and during the process of boiling tap water in the high-temperature boiling water circuit, the heated tap water will flow through the second phase change device multiple times, at which time the second phase change device can absorb the heat in the tap water, and the high-temperature boiling water circuit can charge the second phase change device.

[0022] Specifically, the first phase change device and the second phase change device are both made of phase change heat storage material.

[0023] Specifically, the functions and principles of the above-mentioned waterways are briefly introduced below: Normal temperature water circuit: The water flows directly from the source. Although the water passes through the electric heating device when it comes out, the electric heating device is not started at this time, so the output water is normal temperature water.

[0024] Refrigeration water circuit: The refrigeration device is a cold water tank. The water source is cooled by the cold water tank, and the rear end passes through the electric heating device but is not heated, and outputs cold water; 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, the flowing water can be slightly heated. Specifically, a temperature sensor is set in the first phase change device. The temperature data is used to control the heating power of the rear electric heating device. When the first phase change device heats the water to a certain temperature, the power of the side electric heating device can be reduced accordingly, which can save more electricity. Power-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 thermal 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 flow time of water in the high-temperature boiling water circuit). This water circuit is mainly used for small-scale heating (predetermined temperature threshold, less than 100 degrees Celsius). A temperature sensor is set at the water outlet of the water dispenser. When the temperature sensor senses that the outlet water temperature has a large deviation from the temperature required by the user, it automatically switches to the electric heating water circuit; Electrolysis water circuit: an alkaline water tank, a gas tank and a pressurizing device are provided on it. Pure water enters the electrolysis device, and the generated alkaline water with hydroxide ions enters the alkaline water tank for storage. The generated oxygen is directly discharged to the water outlet of the water dispenser, and the generated hydrogen is stored in the gas tank by the pressurizing device. When the user chooses sparkling water, the pressurizing device is used to add hydrogen to the water. The water stored in the alkaline water tank can be used as a water source and enters the various water circuits.

[0025] High-temperature boiling water circuit: An external hot water tank is arranged on it. The water in the hot water tank enters the electric heating device for heating and then returns to the hot water tank. After multiple cycles, the temperature sensor in the hot water tank senses the boiling temperature (100 degrees Celsius) and then outputs it. During the water circulation process, since the second phase change device is arranged in the high-temperature boiling water circuit, it will absorb 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.

[0026] Specifically, various waterways in the present application are formed by interconnecting multiple pipes, and some pipes are shared between different waterways.

The chip of the water dispenser controls each control water valve to open or close the corresponding valve ports to control the connection of each corresponding pipeline, so that the corresponding water path is connected or disconnected. Specifically, a water pump (1)-(3) is also arranged to drive water from the water source side along the corresponding water path to the water outlet of the water dispenser.

Specifically, the starting and stopping of the water pumps are coordinated with each other. For example, when water needs to be boiled at a high temperature, the water pump (1) stops, the water dispenser does not produce water, and the water pump (2) starts to drive the water to circulate continuously in the high-temperature boiling water path.

[0035] Specifically, the present application provides a fourteenth pipeline ⑭ and a fifteenth pipeline ⑮ respectively connected to the tap water source and the pure water tank. Specifically, the control water valve h (three-way valve) is connected to the fourteenth pipeline ⑭.

[0037] Specifically, the following is a water outlet control method for a water dispenser water circuit, comprising the following steps: Step 1: Determine whether the water is purified water, if so, proceed to step 2; if not, determine that it is tap water, proceed to step 3; wherein, Step 2 is: determine whether to enter the electrolysis mode, if yes, enter the electrolysis water circuit; if no, enter step 3; wherein Step 3 is: determine whether refrigeration is needed, if so, then refrigeration water circuit; if not, enter step 4; wherein, Step 4 is: determine whether heating is required, if so, proceed to step 5 and step 6 at the same time, if not, the normal temperature water channel is opened; wherein, Step 5 is: judging whether the temperature exceeds the predetermined temperature threshold, if so, taking the judgment result of step 1, if the judgment result is pure water, the electric heating water circuit is connected, 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 judges that the water reaches the boiling temperature, the high-temperature boiling water circuit is closed, and the electric heating water circuit is connected; Step 6 is: determine whether the water temperature reaches a predetermined temperature threshold, if so, save electricity to heat the water channel, if not, heat the water channel electrically.
