The bubble water preparation device further comprises a water tank 100 and a refrigerating device 130, the mixing container 50 is arranged in the water tank 100, the refrigerating device 130 is used for cooling water in the water tank 100, liquid in the mixing cavity 51 can be indirectly cooled, the temperature of the liquid in the mixing cavity 51 is adjusted, and the temperature adjusting function is achieved. Compare in direct liquid cooling to in the hybrid chamber 51, this scheme can separate refrigerating plant 130 and the inside water purification of hybrid chamber 51 to improve the health nature and the cleanliness factor of the bubble water that obtains of preparation, also be favorable to improving hybrid chamber 51's space utilization, be convenient for once only make more bubble water.

The booster pump 120 is utilized to convey the pressurized purified water to the mixing cavity 51, so that the water supply efficiency is improved, the timely supply of the purified water is ensured, the purified water amount pumped into the mixing cavity 51 can be controlled by controlling the starting and stopping of the booster pump 120, and the purpose of adjusting the liquid water level of the mixing cavity 51 is achieved.

By adjusting the volume of the mixing chamber 51 by controlling the position of the partition 513, the amount of bubble water prepared by different mixing chambers 51 can be adjusted to meet different needs of consumers.

Specifically, step S204 specifically includes:

step S2042: starting the refrigerating device 130 to make the liquid temperature of the mixing cavity 51 reach the set temperature corresponding to the bubble water concentration signal;

step S2044: starting the booster pump 120 to supply water to the mixing cavity 51, so that the liquid level of the mixing cavity 51 reaches a set water level corresponding to the bubble water concentration signal;

step S2046: opening the gas path control valve 40 to inject carbon dioxide gas into the mixing cavity 51, so that the internal pressure of the mixing cavity 51 reaches the set pressure corresponding to the bubble water concentration signal;

step S2048: the bubble water corresponding to the bubble water concentration signal is obtained by detecting that the internal pressure of the mixing chamber 51 reaches the set pressure, the liquid temperature reaches the set temperature, and the liquid level reaches the set level.

Since the mixing chamber 51 is a closed container with a constant volume, the production of bubble water with different concentrations can be realized by accurately controlling the internal temperature, pressure and water level, thereby breaking through the function setting of the conventional water dispenser 200 and providing bubble water with various concentrations for consumers. Specifically, according to the ideal gas state equation: when PV ═ nRT (P is the pressure of the ideal gas in the closed space, V is the volume of the ideal gas in the closed space, n is the amount of the substance of the ideal gas in the closed space, T is the temperature of the gas in the closed space, and R is an ideal gas constant), n can be obtained from P, V, T if the above equations are satisfied among the internal pressure of the mixing chamber 51, the temperature of the gas, the amount of the substance of the gas, and the volume of the gas; when the total amount of carbon dioxide fed into the mixing chamber 51 is known, the amount of carbon dioxide dissolved in the purified water can be calculated, and the concentration C of the bubble water can be obtained. Since the volume of the mixing chamber 51 is fixed, there is a one-to-one correspondence between the volume of gas inside the mixing chamber 51 and the liquid level, and the gas temperature and the liquid temperature can be considered to be approximately equal. Therefore, the concentration C of the bubble water can be adjusted by adjusting the internal pressure, the liquid temperature, and the liquid level of the mixing chamber 51, and the bubble water concentration can be adjusted steplessly.

Therefore, when it is detected that the internal pressure of the mixing chamber 51 reaches the set pressure, the liquid temperature, and the liquid level simultaneously reach the set values corresponding to the bubble water concentration signal, the obtained concentration of the bubble water is the desired concentration.

Wherein, the corresponding relation between the internal pressure of the mixing chamber 51, the liquid temperature and the liquid level and the concentration of the bubble water can be obtained according to the test, and a corresponding table with mapping association is obtained and stored in the controller; the internal pressure of the mixing chamber 51, the liquid temperature and the functional equation between the liquid level and the concentration of the bubble water can also be experimentally obtained and stored in the controller.

The order of step S2042, step S2044 and step S2046 and whether to intersect or not are not limited as long as the internal pressure, the liquid temperature and the liquid level of the mixing chamber 51 finally meet the set requirements.

Optionally, the refrigeration device 130 is turned on to make the liquid temperature of the mixing chamber 51 reach the set temperature corresponding to the bubble water concentration signal, specifically: the refrigeration unit 130 is turned on intermittently.

By intermittently turning on the refrigeration device 130, it is advantageous to maintain the temperature of the liquid water constant, to reduce the loss of the refrigeration device 130, to maintain the solubility of carbon dioxide constant, and to adjust the pressure inside the mixing chamber 51.

Optionally, the booster pump 120 is started to supply water to the mixing chamber 51, so that the liquid level of the mixing chamber 51 reaches a set water level corresponding to the bubble water concentration signal, specifically: the booster pump 120 is intermittently turned on until the liquid level of the mixing chamber 51 reaches the set level.

By intermittently starting the booster pump 120, the amplitude of the change in the pressure inside the mixing chamber 51 can be reduced, facilitating rapid achievement of equilibrium.

Optionally, the gas path control valve 40 is opened to inject carbon dioxide gas into the mixing chamber 51, so that the internal pressure of the mixing chamber 51 reaches a set pressure corresponding to the bubble water concentration signal, specifically: the air path control valve 40 is intermittently opened.

By intermittently opening the gas path control valve 40, the carbon dioxide gas is input a small amount of times, which is beneficial to fully dissolving the carbon dioxide gas and quickly reaching the balance.

Further, it is firstly determined that the liquid temperature of the mixing chamber 51 reaches the set temperature and the pressure of the gas tank 10 reaches the preset pressure, and then a bubble water concentration signal is obtained or the booster pump 120 is started to supply water to the mixing chamber 51; the booster pump 120 is first turned on to supply water to the mixing chamber 51, and then the gas path control valve 40 is turned on to inject carbon dioxide gas into the mixing chamber 51.

After the liquid temperature of the mixing cavity 51 is judged to reach the set temperature and the pressure of the gas tank 10 reaches the preset pressure, the bubble water concentration signal is obtained or the booster pump 120 is started, the constancy of the carbon dioxide solubility is favorably maintained, and the bubble water prepared by still starting the gas circuit control valve 40 to supply gas when the gas tank 10 is empty or the gas amount is insufficient is prevented from being unqualified.

Of course, it is also possible to first obtain the bubble water concentration signal or turn on the booster pump 120, and then detect whether the outlet pressure of the gas tank 10 reaches the preset pressure.

The booster pump 120 is started first, and then the air path control valve 40 is started, so that the carbon dioxide can enter the mixing cavity 51 after the liquid amount in the mixing cavity is sufficient, the carbon dioxide is fully dissolved in the purified water, and the danger caused by overlarge internal pressure of the mixing cavity 51 is prevented.

Of course, the air path control valve 40 may be opened first, and then the booster pump 120 may be opened as long as the internal pressure, the liquid temperature, and the liquid level of the mixing chamber 51 finally reach the set requirements.

Alternatively, the water level is set to the rated water level of the mixing chamber 51.

The water level is set to be the rated water level of the mixing cavity 51, the water level is set to be a fixed value, and finally the concentration of the bubble water can be adjusted only by adjusting the temperature and the internal pressure of the liquid in the mixing cavity 51, so that the control procedure is simplified.

The difference from the first embodiment is that: the booster pump 120 is started to supply water to the mixing chamber 51, so that the liquid water level of the mixing chamber 51 reaches the set water level corresponding to the bubble water concentration signal, specifically:

the booster pump 120 is continuously turned on until the liquid level of the mixing chamber 51 reaches the set level.

By continuously turning on the booster pump 120, the turn-on frequency of the booster pump 120 can be reduced, and the service life of the booster pump 120 can be improved.

The quantity of the bubble water concentration required to be output needs to be judged, and the quantity of the bubble water concentration required to be output can be specifically determined through the quantity of the bubble water concentration input by a user. If it is required to output bubble water with a certain concentration, the first bubble water chamber 511 is selected to perform steps S900 and S904 to S908. If two bubble water with the concentration of C1 and the concentration of C2 are required to be prepared, the first bubble water chamber 511 and the second bubble water chamber 512 are selected, steps S900 and S904 to S908 are performed, and steps S902 to S908 are performed simultaneously.
