[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a bubble ice water machine, and the bubble ice water machine includes:

[0044] A bubble water treatment system 100, the bubble water treatment system 100 comprises a refrigeration device 110 and a bubble water production device 120, the bubble water production device 120 is used to produce bubble water;

[0045] A water inlet system 200, wherein the water inlet system 200 is connected to the bubble water treatment system 100 through a pipeline, and the water inlet system 200 is used to provide a water source;

[0046] An air intake system 300, the air intake system 300 is connected to the bubble water making device 120 through a pipeline, and the air intake system 300 is used to transport air to the bubble water making device 120;

[0047] A water outlet system 400, the water outlet system 400 comprises a water outlet pipe and a corresponding water outlet end 450, the water outlet pipe comprises a bubble water outlet pipe 410, the water outlet end 450 comprises a bubble water outlet end 450, the bubble water outlet pipe 410 is sequentially provided with a pressure reducing valve 411, a second pressure switch 412, a third solenoid valve 415, and a bubble water outlet end 450, an air pump 500 is provided between the third solenoid valve 415 and the bubble water outlet end 450;

[0048] When the third solenoid valve 415 is closed, the air pump 500 is used to pass gas into the bubble water outlet pipe 410 to blow out the bubble water in the bubble water outlet pipe 410 .

[0049] The bubble water treatment system 100 is used to make bubble water, and the refrigeration device 110 is responsible for lowering the temperature of water to provide a necessary cold source for making ice water or bubble ice water. The bubble water making device 120 generates bubble water by combining refrigerated water and CO2 gas (through a specific device (such as a bubble bladder). The water inlet system 200 is used to provide a water source to the bubble water treatment system 100. The air inlet system 300 is used to deliver gas to the bubble water making device 120, and the gas is mixed with the refrigerated water to form bubble water. The water outlet pipeline includes a bubble water outlet pipeline 410, which is used to output bubble ice water, and the water outlet end 450 includes a bubble water outlet end 450. The pressure reducing valve 411 is used to adjust the pressure in the bubble water outlet pipeline 410 to ensure that the output bubble water is stable. The pressure switch 412 is used to monitor the pressure in the water outlet pipeline, and when the pressure reaches a preset value, trigger a corresponding action (such as closing the solenoid valve). The air pump 500 is arranged between the third solenoid valve 415 and the bubble water outlet end 450, and is used to pass gas into the pipeline after the bubble water is output to blow out the residual bubble water. By controlling the opening time and duration of the air pump 500, the opening time of the air pump 500 is adjusted according to the concentration of the bubble water and the length of the pipeline.

[0050] The working process of the bubble water chiller is as follows: first, the staff presses the start button and the bubble water chiller starts to operate. At this time, the water inlet system 200 starts to supply water to the bubble water treatment system 100; then, the refrigeration device 110 (such as a compressor and a condenser) starts to work to lower the temperature of the water. At the same time, the filter will remove impurities in the water to ensure the cleanliness of the water. The refrigerated water enters the bubble bladder through the pipeline and is ready to be mixed with the gas; then, the air intake system 300 starts to work and delivers CO2 to the bubble bladder. The amount and speed of CO2 can be controlled by the regulating device of the air intake system 300. In the bubble bladder, the refrigerated water is mixed with the gas to form bubble ice water; then, the third solenoid valve 415 is opened, and the bubble ice water flows out from the bubble water outlet end 450 through the bubble water outlet pipeline 410; finally, the third solenoid valve 415 is closed, and the air pump 500 introduces gas into the bubble water pipeline to remove residual bubble water.

[0051] In the embodiment of the present invention, an air pump 500 is arranged on the bubble water outlet pipe 410, and gas is introduced into the pipe by using the air pump 500 after the third solenoid valve 415 is closed when the bubble water is output. The air pump 500 can successfully blow out the residual bubble water from the bubble water outlet pipe 410, thereby effectively solving the problem of bubble water remaining in the bubble water outlet pipe 410. The present invention can control the opening time and duration of the air pump 500 and adjust it according to the concentration of the bubble water and the length of the pipe, thereby realizing the control of the cleaning of the bubble water output pipe and improving the flexibility of the bubble ice machine.

[0052] like Figure 2-3As shown, in an optional embodiment of the present invention, the refrigeration device 110 is connected to the bubble water making device 120 via a refrigeration pipe 440, and the refrigeration pipe 440 is sequentially provided with a first solenoid valve 413, a booster pump and a first one-way valve 600, and the ice water produced by the refrigeration device 110 flows into the bubble water making device 120 through the refrigeration pipe 440.

[0053] Among them, the refrigeration device 110 is responsible for cooling the water source to a preset low temperature state to prepare ice water. The refrigeration pipe 440 serves as a bridge connecting the refrigeration device 110 and the bubble water making device 120, and the refrigeration pipe 440 is responsible for transmitting the cooled ice water. The first solenoid valve 413 is arranged in the refrigeration pipe 440 to regulate the flow of ice water. The booster pump is installed in the refrigeration pipe 440 to increase the flow pressure of the ice water to ensure that it can flow smoothly and efficiently into the bubble water making device 120.

[0054] like Figure 2-3 As shown, in an optional embodiment of the present invention, the air intake system 300 includes a CO2 gas tank, a first pressure switch 412, a second one-way valve 610, and an air inlet which are arranged in sequence through a pipeline, and the air inlet is arranged in the bubble water making device 120.

[0055] The function of the first pressure switch 412 is to detect the pressure of CO2 in the CO2 tank. When it reaches a certain set value, the system can draw bubble water. When it is less than a certain set value, the system cannot make bubble water, and the air shortage indicator lights up, indicating that the CO2 tank needs to be replaced. The function of the second one-way valve 610 here is to prevent the pressure of the bubble water tank from being too high, which will press the bubble water back to the CO2 tank outlet pipe, especially into the pressure reducing valve 411, causing the pressure reducing valve 411 to malfunction.

[0056] Specifically, in the bubble water making device 120, the gas introduced through the air inlet is mixed with the ice water flowing in from the refrigeration pipe 440. Since the air intake system 300 has accurately regulated the gas content, it can ensure that the gas is evenly distributed in the water to form delicate and stable bubbles. The right amount of gas content gives the bubble water a unique bubble feeling and a refreshing drinking experience. Too much gas will make the beverage too bloated, while too little gas will make the beverage bland. Therefore, the regulation of the air intake system 300 is crucial to improving the taste of the bubble water.

[0057] In an optional embodiment of the present invention, the water outlet pipe includes an ice water outlet pipe 420, the water outlet end 450 includes an ice water outlet end 450, the refrigeration system includes a compressor, a condenser, a filter, a capillary, an ice liner 111, and an evaporator coil arranged in sequence through pipes, the bubble water making device 120 includes a bubble liner, one end of the bubble water outlet pipe 410 and one end of the refrigeration pipe 440 are arranged in the bubble liner, the other end of the refrigeration pipe 440 is arranged in the ice liner 111, one end of the ice water outlet pipe 420 is connected to the refrigeration pipe 440 from the ice liner 111 to the first solenoid valve 413, the other end of the ice water outlet pipe 420 is the ice water outlet end 450, and the ice water outlet pipe 420 is provided with a second solenoid valve 414.

[0058] Among them, the compressor compresses the refrigerant to release heat in the condenser, thereby reducing the water temperature in the evaporator coil. After the refrigerant in the condenser is liquefied, its temperature and pressure are reduced to prepare for the subsequent expansion process. The filter can remove impurities and particulate matter in the water to ensure the clean water quality. The bubble liner is used to mix the refrigerated water with the gas. The ice liner 111 is used to make ice water. The evaporator coil is used in the refrigeration cycle, and the evaporator coil absorbs heat from the water to reduce the water temperature. The various components are connected by pipes and joints to form a refrigeration cycle and bubble water production process. The compressor output end is connected to the condenser input end, the condenser output end is connected to the filter input end, the filter output end is connected to the capillary input end, the capillary output end is connected to the evaporator coil input end and the bubble liner input end (part of the refrigerant also enters the ice liner 111 for refrigeration), and the evaporator coil and the bubble liner output end are respectively connected to the corresponding water outlet pipes.

[0059] Specifically, when the bubble water treatment system 100 is started, the compressor starts working, compresses the refrigerant and delivers it to the condenser. After the condenser cools and liquefies the refrigerant, it passes through a filter to remove impurities, and then passes through a capillary tube to reduce pressure and partially vaporize. The vaporized refrigerant enters the evaporator coil, absorbs heat from the water and lowers the water temperature. The user can choose to output bubble water or ice water as needed, and adjust the water output type through the control panel.

[0060] Specifically, when ice water needs to be supplied to the user, the second solenoid valve 414 is opened, and the ice water flows out from the ice bladder 111, passes through the refrigeration pipe 440 and reaches the ice water outlet 450. When ice water is not needed, the second solenoid valve 414 is closed to prevent the ice water from being lost in vain and to keep the water temperature in the ice bladder 111 constant. When bubble ice water needs to be made, the first solenoid valve 413 is opened, and the ice water flows from the ice bladder 111 into the bubble bladder and mixes with the gas to form bubble ice water. When bubble ice water is not needed, the first solenoid valve 413 is closed to prevent ice water from entering the bubble bladder and affecting the taste and quality of the bubble water. The opening and closing of the second solenoid valve 414 directly controls whether the ice water flows to the ice water outlet 450 to meet the user's direct drinking needs. When the first solenoid valve 413 is opened, the booster pump is started to increase the pressure of the ice water flowing to the bubble bladder to ensure the production effect of the bubble ice water. When the first solenoid valve 413 is closed, the booster pump stops working to prevent unnecessary energy consumption.

[0061] In the embodiment of the present invention, the bubble water treatment system 100 in the optional embodiment of the present invention realizes efficient and stable production of bubble water and ice water through the coordinated action of various components.

[0062] like Figure 2-3 As shown, in an optional embodiment of the present invention, the ice bladder 111 is provided with an ice bladder 111 temperature sensing module, and the bubble bladder is provided with a bubble bladder high water level sensing module and a bubble bladder low water level sensing module.

[0063] Specifically, when the temperature sensing module of the ice tank 111 detects that the water temperature is too high, the control system will start the refrigeration system to lower the water temperature; when the high water level sensing module of the bubble tank detects that the water level is too high, the control system will stop the water replenishment process; when the low water level sensing module of the bubble tank detects that the water level is too low, the control system will start the water replenishment process to replenish the water.

[0064] In an optional embodiment of the present invention, the water outlet pipe includes a clean water outlet pipe 430, the water outlet end 450 includes a clean water outlet end 450, the clean water outlet pipe 430 is divided into three branch pipes, one end of the first branch pipe is arranged in the water inlet system 200, the other end of the first branch pipe is the clean water outlet end 450, one end of the second branch pipe is connected to the first branch pipe in the direction close to the water inlet system 200, the other end of the second branch pipe is arranged in the ice chamber 111, one end of the third branch pipe is arranged in the ice chamber 111, the other end of the third branch pipe is connected to the first branch pipe in the direction away from the water inlet system 200, the first branch pipe is provided with a fourth solenoid valve 416, the third branch pipe is provided with a third one-way valve 620, and the third one-way valve 610 is used to exhaust when water from the water inlet system 200 enters the ice chamber 111.

[0065] Among them, one end of the first pipeline is directly connected to the water inlet system 200, and is used to directly obtain water from the water inlet system 200. The other end serves as the purified water outlet 450, and is used to output purified water. A fourth solenoid valve 416 is provided on this pipeline, and is used to control the output of purified water. One end of the second pipeline is connected to the direction of the first pipeline close to the water inlet system 200, that is, it diverts a part of the water source from the first pipeline. The other end is provided in the ice liner 111, and is used to inject water into the ice liner 111 to make ice water. One end of the third pipeline is provided in the ice liner 111, and is used to allow the gas in the ice liner 111 to be discharged through the third one-way valve 620 when the water from the water inlet system 200 enters the ice liner 111, so as to prevent the gas from being unable to be discharged.

[0066] like Figure 2-3 According to another aspect of the present invention, a control method for the above-mentioned bubble ice machine is also provided, characterized in that the method comprises:

[0067] S10, supplying water to the bubble water treatment system through the water inlet system;

[0068] S20, refrigerating the water by a refrigeration device, and transporting the refrigerated water to the bubble liner through an ice water outlet pipe;

[0069] S30, inputting CO2 into the bubble chamber through the air intake system to prepare bubble ice water;

[0070] S40, opening the third solenoid valve to output the bubble ice water from the bubble water outlet pipe;

[0071] S50, closing the third solenoid valve, and blowing out the bubble ice water remaining in the bubble water outlet pipe through the air pump.

[0072] The control method of the bubble water chiller is as follows: first, the staff presses the start button, and the bubble water chiller starts to operate. At this time, the water inlet system 200 starts to supply water to the bubble water treatment system 100; then, the refrigeration device 110 (such as a compressor and a condenser) starts to work to reduce the temperature of the water, and the refrigerated water enters the bubble bladder through a pipeline to prepare for mixing with the gas; then, the air intake system 300 starts to work to transport CO2 into the bubble bladder, and the amount and speed of CO2 can be controlled by the regulating device of the air intake system 300. In the bubble bladder, the refrigerated water is mixed with the gas to form bubble ice water; then, the third solenoid valve is opened, and the bubble ice water flows out from the bubble water outlet end through the bubble water outlet pipeline 410; finally, the third solenoid valve is closed, and the air pump 414 introduces gas into the bubble water pipeline to remove residual bubble water.

[0073] In an embodiment of the present invention, an air pump is arranged on the bubble water outlet pipe, and gas is introduced into the pipe by using the air pump after the third solenoid valve is closed when the bubble water is output. The air pump can successfully blow out the residual bubble water from the bubble water outlet pipe, effectively solving the problem of bubble water remaining in the bubble water outlet pipe. The present invention can control the opening time and duration of the air pump and adjust it according to the concentration of the bubble water and the length of the pipe, thereby realizing the control of the cleaning of the bubble water output pipe and improving the flexibility of the bubble ice machine.

[0074] like Figure 4 As shown, in an optional embodiment of the present invention, the specific steps of preparing bubble ice water are:

[0075] S21, opening the first solenoid valve and starting the booster pump to transport the ice water in the ice liner to the bubble liner through the refrigeration pipeline;

[0076] S22, delivering CO2 to the bubble bladder through the air intake system, wherein the delivery amount is adjusted according to the amount of ice water in the bubble bladder;

[0077] S23, pressurizing ice water and CO2 through a bubble bladder to prepare bubble ice water.

[0078] Specifically, in S21, the first solenoid valve is opened so that the ice water in the ice bladder begins to flow. Next, the booster pump is started, which provides the necessary pressure for the ice water to ensure that the ice water can be smoothly and efficiently transported to the bubble bladder through the refrigeration pipe. In S23, in the bubble bladder, the ice water and the gas are mixed at a specific pressure. This mixing process not only enables the gas to be evenly dissolved in the ice water, but also through the pressurization effect, the dissolved gas forms tiny and stable bubbles in the ice water. Finally, these ice waters rich in bubbles are prepared into bubble ice water.

[0079] In an optional embodiment of the present invention, before S50, the method includes the following steps:

[0080] S45, determining the duration of the air pump being turned on as t milliseconds according to the concentration of the bubble water and the distance from the bubble water outlet of the third solenoid valve;

[0081] S46, turning on the air pump for t milliseconds and then turning off the air pump.

[0082] Among them, S45, the system calculates the duration t milliseconds that the air pump should be turned on based on the concentration of the bubble water (for example, measured by a concentration sensor) and the distance from the third solenoid valve to the bubble water outlet (for example, obtained through preset pipeline layout data). For example, if the concentration of the bubble water is high and the pipeline is long, the system may calculate a longer duration t milliseconds to ensure that the pipeline is fully cleaned. S46, the system turns on the air pump to clean the pipeline according to the duration t milliseconds calculated in step S45. When the preset cleaning time t milliseconds is reached, the system promptly turns off the air pump and ends the pipeline cleaning phase.

[0083] The control method of the present invention realizes a more refined pipeline cleaning process and improves the cleaning performance of the bubble chiller.

[0084] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
