Description

Technical Field

[0001] The present invention relates to the field of hydrogen-rich water drinking machines, and in particular to a hydrogen-rich water drinking machine device and a control method thereof. Background Art

[0002] Nowadays, with the development of the times, people pay more and more attention to health issues. Scientific research shows that hydrogen plays a great role in anti-oxidation and maintaining human health. Existing hydrogen-rich water dispensers all use pure water barrels to replenish water sources, and require manual water replenishment at intervals, which brings great inconvenience to users. Moreover, the hydrogen-rich water dispensers on the market only have the function of producing hydrogen-rich water. As household or commercial water dispensers, they must be equipped with pure water machines, which undoubtedly increases the cost burden and space requirements. Existing hydrogen-rich water dispensers cannot automatically replenish water and cannot alarm when a fault occurs. Therefore, there is still a gap in the technical field of hydrogen-rich water dispenser devices that combine automatic water replenishment functions with safety prompts and alarm functions.

[0003] Therefore, based on the above-mentioned problems, it is necessary to design a hydrogen-rich water drinking machine with automatic water replenishment function. At the same time, the device can also be used as an ordinary water drinking machine, and has functions such as one-button start and stop, one-button water making, and can perform water level alarm, hydrogen elimination, fault alarm and power-off protection. Summary of the invention

[0004] The purpose of the present invention is to provide a hydrogen-rich water drinking machine device that integrates the functions of automatic water replenishment, one-button start and stop, and one-button water production, and can realize water level alarm, hydrogen elimination, fault alarm and power-off protection, so as to solve the problems in the prior art that the hydrogen-rich water drinking machine device cannot automatically replenish water, cannot be used by multiple people, and is not convenient for safety fault troubleshooting.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a hydrogen-rich water drinking machine device, which includes a raw water tank, a hydrogen-rich water tank, a gas-water separator, a water pump, a solenoid valve, a fan, an electrolyzer, a flow sensor, and a pressure sensor, wherein the water pump includes a circulation pump, an air pump, a water replenishment pump, a booster pump, a gas-liquid mixing pump, and a water intake pump.

[0006] The raw water tank includes a liquid level sensor, and the raw water tank is connected to the water source through a solenoid valve, a booster pump, and a water replenishment pump. When the water level in the raw water tank is lower than the threshold, the solenoid valve, the water replenishment pump and the booster pump are turned on to replenish the raw water tank with water to achieve automatic water replenishment; when the liquid level is higher than the threshold, the water replenishment pump and the solenoid valve are closed.

[0007] Similarly, a liquid level sensor is also provided in the hydrogen-rich water tank, and the hydrogen-rich water tank is connected to the water source through a solenoid valve and a water replenishment pump. When the liquid level sensor detects that the water level in the hydrogen-rich water tank is lower than the threshold, the solenoid valve and the water replenishment pump are opened to replenish the hydrogen-rich water tank to achieve automatic water replenishment; when the liquid level is higher than the threshold, the water replenishment pump and the solenoid valve are closed.

[0008] An electrolytic cell, a flow sensor, a circulating pump, a fan, a gas-water separator, and a gas-liquid mixing pump are arranged between the raw water tank and the hydrogen-rich water tank. The water in the raw water tank is pumped into the electrolytic cell by the circulating pump for electrolysis. The hydrogen produced after the electrolysis of water is separated by the gas-water separator and mixed by the gas-liquid mixing pump to obtain hydrogen-rich water, which can then be taken out by the water extraction pump.

[0009] The gas-water separator also includes a liquid level sensor and a drain valve. When the liquid level sensor detects that the liquid level inside is higher than a threshold value, the drain valve is opened to drain the water into the raw water tank.

[0010] The hydrogen-rich water tank also includes a pressure sensor for detecting the pressure value in the hydrogen-rich water tank. When the pressure exceeds a threshold, the power supply of the electrolyzer is cut off and hydrogen is eliminated.

[0011] The hydrogen dehydrogenation chamber is equipped with a catalyst. When hydrogen overflows from the hydrogen-rich water tank, the air pump is started to dehydrogenate the corresponding hydrogen.

[0012] The electrolytic cell is also provided with a flow sensor S1, which is used to monitor whether the electrolysis process is normal and to cut off the power if there is any abnormality.

[0013] The hydrogen-rich water dispenser also includes a water leakage detector, which can detect, cut off power and alarm when water leaks occur in various parts of the dispenser.

[0014] The water dispenser device also includes a touch screen, a single-chip microcomputer controller, a buzzer and an indicator light. The single-chip microcomputer is used to process data. When water leakage, water level or flow abnormality occurs, an alarm can be given through the buzzer and indicator light. When water production is completed or in the water production state, different lights are displayed through the indicator light.

[0015] The single chip microcomputer uses STM32F103RBT6 as the core single chip microcomputer. In addition to the above functions, the single chip microcomputer is also used to control the start and stop of each solenoid valve and pump body.

[0016] Water production and water extraction are triggered by touching the button. After power is turned on and the water production button is pressed, the relay controls the DC power supply to start working, the electrolyzer starts to produce hydrogen, the circulation pump starts working to keep the electrolyte circulating, the gas-liquid mixing pump, the air pump and the fan start working. After a period of water production, the DC power supply is cut off, and the circulation pump, gas-liquid mixing pump, air pump and fan are cut off. After the water production is completed, the buzzer and indicator light can be used to prompt that the water outlet button is pressed, and the water extraction pump starts to work and continuously discharge water. Press the button again and the water extraction pump stops working. In addition, when the flow sensor at the electrolyzer and the pressure sensor of the hydrogen-rich water tank are abnormal, the power-off protection action can be executed.

[0017] At the same time, a method for automatically controlling a hydrogen-rich water dispenser is also provided, which comprises the following steps:

[0018] Step 1: The water leakage detector detects whether there is water leakage in each component of the water dispenser. If there is water leakage, the power supply is cut off and an alarm is sounded;

[0019] Step 2: If there is no water leakage, the liquid level sensors in the raw water tank and the hydrogen-rich water tank detect the water levels in the two tanks to determine whether to start water replenishment. If the water level is lower than the threshold, the solenoid valve and the water replenishment pump are turned on to replenish water. If it is higher than the threshold, the water replenishment pump and the solenoid valve are turned off to stop replenishing water.

[0020] Step 3: If water replenishment is not required, determine whether a button is pressed. If no button is pressed, continue to detect. If a button is pressed, determine whether it is in the water making or water taking state;

[0021] Step 4: If the water production button is pressed, the flow detector and pressure sensor detect whether there is any abnormality in the flow. If there is any abnormality, the power supply is cut off to alarm. If there is no abnormality, the electrolytic cell, circulation pump and fan are turned on to produce water. After the water production is completed, the hydrogen-rich water indicator light turns on.

[0022] Step 5: If the water making key is not pressed, determine whether the water dispensing button is pressed. If the water dispensing key is pressed, start the water pump to discharge water. When the water dispensing button is pressed again, stop dispensing water, and the water dispensing is completed.

[0023] Beneficial effects of the present invention

[0024] In the present invention, the hydrogen generation process is environmentally friendly, the gas flow rate of the electrolyzer is large, high-purity hydrogen is fully dissolved in water, the water production time is short, the hydrogen-rich water produced has a high hydrogen content, and the process is safe and stable. The present invention can meet the needs of multiple people, is simple to operate, and is convenient and fast.
