[0003] This utility model provides a sparkling water preparation system and beverage machine that can be used to stably prepare sparkling water.

[0004] To address the aforementioned technical problems, this utility model provides a sparkling water dispensing system for use in beverage machines. The sparkling water dispensing system includes:

[0005] An ice water preparation mechanism, used to prepare ice water;

[0006] A sparkling water tank is connected to the ice water preparation mechanism via an added pump and the first end of a first reversing valve to obtain ice water;

[0007] A control valve is located in the passage between the reversing valve and the sparkling water tank, and is used to control the injection of ice water into the sparkling water tank at a specified pressure.

[0008] An air intake assembly, connected to the sparkling water tank, is used to introduce carbon dioxide gas, which mixes with ice water to prepare sparkling water.

[0009] The water outlet assembly is connected to the water outlet of the sparkling water tank and the beverage machine, and is used to output sparkling water.

[0010] In some embodiments, the control valve is a throttle valve, which can control the pressurized ice water to be injected into the sparkling water tank at a specified pressure, including 4 bar.

[0011] In some embodiments, the air intake assembly includes an air intake pipe, a valve disposed on the air intake pipe, and a pressure gauge.

[0012] In some embodiments, the valve is a second reversing valve, with a first end connected to the air intake pipe and a second end connected to the atmosphere. When the booster pump pumps water, the second reversing valve opens the second end to depressurize the bubble water tank.

[0013] In some embodiments, a one-way valve is provided at the end of the air intake pipe connected to the bubble water tank.

[0014] In some embodiments, a water level probe is also included, disposed inside the bubble water tank, for detecting the water level;

[0015] The booster pump stops pumping water when the water level detection result indicates that the water level has reached the water level probe, and starts pumping water when the water level detection result indicates that the water level is lower than the water level probe.

[0016] In some embodiments, the second end of the first reversing valve is connected to the water outlet end for outputting chilled water.

[0017] In some embodiments, a three-way connector is also included, wherein the water outlet, the second end of the first reversing valve, and the air inlet pipe are respectively connected to the three connecting ends of the three-way connector.

[0018] In some embodiments, the ice water preparation mechanism includes a refrigeration system and a cold tank connected to the refrigeration system.

[0019] Another embodiment of this utility model also provides a beverage machine, including the sparkling water dispensing system as described in any of the embodiments above.

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] like Figure 1 As shown, this utility model embodiment provides a sparkling water dispensing system for use in beverage machines. The sparkling water dispensing system includes:

[0040] An ice water preparation mechanism, used to prepare ice water;

[0041] The sparkling water tank 07 is connected to the ice water preparation mechanism via an added pump and the first end of the first reversing valve 04, and is used to obtain ice water;

[0042] A control valve is provided in the passage between the reversing valve and the bubble water tank 07, and is used to control the injection of the ice water into the bubble water tank 07 at a specified pressure.

[0043] An air intake assembly, connected to the bubble water tank 07, is used to introduce carbon dioxide gas, which mixes with ice water to form bubble water.

[0044] The water outlet assembly is connected to the sparkling water tank 07 and the water outlet 16 of the beverage machine, and is used to output sparkling water.

[0045] For example, continue to combine Figure 1 As shown, based on the disclosure of the above embodiments, it can be understood that the beneficial effects of the present utility model include: a preparation ice water preparation mechanism; a sparkling water tank 07 connected to the ice water preparation mechanism via an added pump and a first end of a first reversing valve 04; a control valve located in the passage between the reversing valve and the sparkling water tank 07 for controlling the injection of ice water into the sparkling water tank 07 at a specified pressure; a carbon dioxide gas introduced into the sparkling water tank 07 for mixing with the ice water to form a sparkling water inlet assembly; and a sparkling water outlet assembly connected to the sparkling water tank 07 and the water outlet 16 of the beverage machine for outputting sparkling water. Thus, the sparkling water preparation system of this application can be obtained. When the booster pump 03 pumps water, the end of the first reversing valve 04 that is open to the atmosphere is opened to remove the pressure in the sparkling water tank 07. When pumping stops, this end is closed, and the end connected to the outlet is opened. At the same time, the second reversing valve 09, which delivers carbon dioxide gas, is opened, allowing the carbon dioxide gas to enter the sparkling water tank 07 and mix with the ice water to produce sparkling water. When the carbon dioxide gas is introduced, the flow rate is controlled by a set control valve to keep the gas pressure stable near a specified pressure, such as about 4 bar. This reduces the pressure on the sparkling water tank 07, thereby reducing safety risks and improving the safety of product use.

[0046] Furthermore, in this embodiment, the control valve is a throttle valve 05, which can control the pressurized ice water to be injected into the sparkling water tank 07 at a specified pressure, including 4 bar. Other pressure values ​​are also possible; the specific value is not unique and can be flexibly configured according to actual needs.

[0047] In this embodiment, the chilled water is transported through an inlet pipe. The air intake assembly includes an air intake pipe, a valve on the air intake pipe, and a pressure gauge. One end of the air intake pipe is connected to the sparkling water tank 07, and the other end is connected to an air source. The valve is a second directional valve 09. The first end of the second directional valve 09 is connected to the air intake pipe, and the second end is open to the atmosphere. When the booster pump 03 pumps water, the second directional valve 09 opens the second end to depressurize the sparkling water tank 07. At the same time, a pressure relief valve connected to the sparkling water tank 07 can also be provided for depressurization when necessary. Moreover, a one-way valve 06 is provided at the end of the air intake pipe connected to the sparkling water tank 07 to prevent the sparkling water in the sparkling water tank 07 from flowing back into the inlet pipe.

[0048] Continue to combine Figure 1As shown, the system in this embodiment also includes a water level probe 08, which is located inside the bubble water tank 07 and is used to detect the water level. The booster pump 03 stops pumping water when the water level detection result indicates that the water level has reached the water level probe 08, and starts pumping water when the water level detection result indicates that the water level is lower than the water level probe 08.

[0049] Furthermore, in order to enable the beverage machine to simultaneously provide ice water, the second end of the first reversing valve 04 is connected to the water outlet 16 for outputting ice water. Since the water outlet 16 needs to connect to multiple components, in this embodiment, a three-way connector 15 is also connected before the water outlet 16. The water outlet 16, the second end of the first reversing valve 04, and the air inlet pipe are respectively connected to the three connecting ends of the three-way connector 15.

[0050] Specifically, in practical applications, we will continue to combine... Figure 1 , Figure 2 and Figure 3 As shown, the ice water preparation mechanism includes a refrigeration system 02 and a cold tank 01 connected to the refrigeration system 02. When preparing sparkling water, the refrigeration system 02 first cools the water in the cold tank 01 to a fixed temperature. Then, a booster pump 03 pumps the ice water from the cold tank 01 to increase its pressure. Simultaneously, the first end of the first reversing valve 04, which connects to the sparkling water tank 07, is opened, while the second end is closed (i.e., the cold water outlet is closed). Next, a throttle valve 05 controls the pressurized water flow to approximately 4 bar before injecting it into the sparkling water tank 07. During this process, the ice water is transported via an inlet pipe. A one-way valve 06 is installed at the connection point of this pipe to the sparkling water tank 07 to prevent backflow of water from the sparkling water tank 07 into the inlet pipe. The sparkling water tank 07 is equipped with a water level probe 08 to detect the water level. When the water level reaches the probe level, the booster pump 03 stops pumping water. When the water level is lower than the probe level, the pump resumes pumping water. During pumping, the reversing valve 09 opens to the faucet 16, connecting to the atmosphere and removing the pressure inside the sparkling water tank 07. When pumping stops, the atmosphere is closed, and the reversing valve for delivering carbon dioxide gas is opened, allowing the carbon dioxide gas to enter the sparkling water tank and mix with the ice water to produce sparkling water. After the sparkling water preparation is complete, in response to the sparkling water output command, the solenoid valve 13 and the flow regulating valve 14 on the sparkling water output pipeline are opened, and the sparkling water is output from the outlet 16 (the faucet shown in the figure) by the gas pressure.

[0051] Figure 3This is the program control logic of this embodiment. For example, when the water in the sparkling water tank 07 does not reach the water level probe 08, the main control board 19 automatically sends a command to power on and turn on the booster pump 03 to pump water. At the same time, the first reversing valve 04 and the second reversing valve 06 are powered on and opened to replenish water. After the water level reaches the water level probe 08, the booster pump 03, the first reversing valve 04, and the second reversing valve 06 are de-energized, and the water replenishment is completed. After the second reversing valve 06 is de-energized, carbon dioxide gas enters the sparkling water tank 07. When sparkling water is output, the control panel 20 sends a command to the main control board 19. After receiving the command, the solenoid valve 13 is opened, and the sparkling water is output by the pressure in the sparkling water tank 07.

[0052] Another embodiment of this utility model also provides a beverage machine, including the sparkling water dispensing system as described in any of the embodiments above.

The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
