Therefore, they should not be understood as limitations on the present invention.

[0021] As a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, this embodiment provides a control method for a bubble water device, and the bubble water device 100 may include an air supply module 110, a water supply module 120 and a premixing module 130. The air supply module 110 provides carbon dioxide gas for the bubble water, and the water supply module 120 provides a water source for the bubble water. The premixing module 130 premixes the carbon dioxide gas of the air supply module 110 and the water of the water supply module 120 to form bubble water, and stores the bubble water; the premixing module 130 includes a premixing tank 131.

[0022] Specifically, Figure 2 As shown, the control method of the bubble water device 100 of this embodiment may include: Step S100, real-time detection of the liquid level information of the bubble water in the premix tank 131; Step S200, when the liquid level in the premixing tank 131 is lower than a preset range, control the start-up of the gas supply module 110 and the water supply module 120 to provide carbon dioxide gas and water to the premixing tank 131 to form bubble water, until the liquid level of the bubble water in the premixing tank 131 is higher than the preset range; Step S300, in response to the operation instruction, extracting bubble water from the premix tank 131 for use.

[0023] Specifically, the control method of the bubble water device 100 of the present embodiment can maintain the liquid level of the bubble water in the premixing tank 131 within a preset range and store the bubble water according to the detected liquid level of the bubble water in the premixing tank 131, so that when the user takes the bubble water, the mixed bubble water can be directly taken from the premixing tank 131 in real time without the user having to wait, thereby improving the user's experience.

[0024] As a specific embodiment of the present invention, Figure 3 As shown, in step S200 of this embodiment, the step of controlling and starting the gas supply module 110 and the water supply module 120 to provide carbon dioxide gas and water to the premix tank 131 to form bubble water includes: Step S210, exhausting the premixing tank 131; Step S220, after the exhaust continues for a first preset time, the water supply module 120 provides water to the premixing tank 131; Step S230, when the liquid level in the premixing tank 131 is higher than a preset range, the water supply module 120 stops supplying water to the premixing tank 131; Step S240, after the water supply module 120 stops supplying water to the premixing tank 131 for a second preset time, the exhaust valve is closed.

[0025] Specifically, since the premixing tank 131 stores bubble water, the air pressure in the premixing tank 131 is relatively high. Before filling the premixing tank 131 with water, the premixing tank 131 needs to be vented first so that the water in the water supply module 120 can flow smoothly into the premixing tank 131. And after the liquid level in the premixing tank 131 reaches the target liquid level, it is necessary to wait until the second preset time before closing the exhaust valve so that the air pressure in the premixing tank 131 can be stabilized before closing, which is conducive to the subsequent other steps.

[0026] As a specific embodiment of the present invention, Figure 4 As shown, in step S240 of this embodiment, after the water supply module 120 stops supplying water to the premixing tank 131 for the second preset time, the step of closing the exhaust valve may also include: Step S250, starting the gas supply module 110 to supplement the premixing tank 131 with carbon dioxide gas so that the gas in the premixing tank 131 forms bubble water; Step S260 , replenishing carbon dioxide gas to the premixing tank 131 and exhausting the premixing tank 131 are performed alternately until the gas content in the bubble water in the premixing tank 131 reaches a preset level.

[0027] Specifically, after the water in the premixing tank 131 is replenished, the premixing tank 131 needs to be replenished with carbon dioxide gas through the gas supply module 110, and then the carbon dioxide is mixed with water to form bubble water. In addition, since users have different requirements for the taste of bubble water, the content of carbon dioxide in the bubble water can be adjusted as needed to meet the needs of different users. This embodiment adjusts the gas content in the bubble water in the premixing tank 131 by inflating and exhausting the premixing tank 131, thereby ensuring safety and improving the user experience.

[0028] Specifically, the level of bubble water can be divided into levels according to the situation. For example, in the bubble water device 100 of this embodiment, the level of bubble water is divided into three levels. When the user selects the first level, the number of times of alternating inflation and exhaustion is n1 times, when the user selects the second level, the number of times of alternating inflation and exhaustion is n2 times, and when the user selects the third level, the number of times of alternating inflation and exhaustion is n3 times. When the liquid level of the bubble water in the premix tank 131 is low, when refilling the premix tank 131 to form bubble water, the bubble water level can be preferably the first level, the second level, or the third level. When the user has the need to select a level, the level of the bubble water can be adjusted for the user to drink.

[0029] As a specific embodiment of the present invention, Figure 5 As shown, step S260 of this embodiment controls the air supply device to inflate the premixing tank 131 and controls the exhaust valve to exhaust the premixing tank 131 alternately, including: Step S261, start the gas supply device to inflate the premixing tank 131 for a third preset time and then close it; Step S262, venting the premixing tank 131 for a fourth preset time and then closing it; Step S263, repeat the above steps until the number of times matches the preset level.

[0030] Specifically, the alternating inflation and deflation of this embodiment need to last for a certain period of time to ensure that the inflation and deflation are effective. In addition, the inflation and deflation time, as well as the number of inflation and deflation, determine the carbon dioxide content in the bubble water, and thus determine the taste of the bubble water, which can be designed according to actual conditions.

[0031] As a specific embodiment of the present invention, Figure 6 As shown, step S300 of this embodiment, in response to the operation instruction, the step of extracting bubble water from the premix tank 131 for use includes: Step S310, in response to the operation instruction, exhausting the premixing tank 131 for a fifth preset time; Step S320, controlling the discharge of bubble water from the premixing tank 131 until the operation instruction disappears; Step S330, controlling the premixing tank 131 to stop discharging bubble water.

[0032] Specifically, when the present embodiment receives the instruction to take the bubble water, since the premix tank 131 stores bubble water with a relatively high internal pressure, the gas in the premix tank 131 needs to be discharged before the bubble water is taken, so as to avoid the bubble water being discharged too quickly due to the excessive gas pressure in the premix tank 131, thereby affecting the user experience.

[0033] The fifth preset time of this embodiment can be designed according to actual conditions. Generally speaking, the fifth preset time is relatively short, thereby avoiding the problem of poor user experience caused by the user waiting for too long.

[0034] Specifically, after the user's operation instruction disappears, when it is detected that the liquid level in the premixing tank 131 is lower than the preset range, the air supply module 110 and the water supply module 120 are controlled to start providing carbon dioxide gas and water to the premixing tank 131 to form bubble water until the liquid level of the bubble water in the premixing tank 131 is higher than the preset range.

[0035] This process is specifically designed to ensure that the next user can use the sparkling water in a timely manner, thereby improving the user experience.

[0036] As another specific embodiment of the present invention, Figure 7 As shown, step S300 of this embodiment controls the extraction of bubble water from the premix tank 131 for use in response to the operation instruction, including: Step S340, in response to the operation instruction, controlling the premixing tank 131 to exhaust gas for a fifth preset time; Step S350, controlling the discharge of bubble water from the premixing tank 131 until the liquid level in the premixing tank 131 is lower than a preset range; Step S360, controlling the premixing tank 131 to stop emitting bubble water.

[0037] Specifically, in this embodiment, before taking the bubble water, since there are many other things in the premix tank 131, it is necessary to exhaust the gas in the premix tank 131 first to avoid the problem of too rapid discharge of the bubble water. In addition, in the process of taking the bubble water from the premix tank 131, the liquid level of the bubble water will continue to drop. When the user takes the bubble water at a low level, the premix tank 131 stops discharging the bubble water. At this time, the user's operation interface will flash, prompting the user that the bubble water level is too low and please wait for a while.

[0038] Specifically, when the premixing tank 131 stops discharging water, the air supply module 110 and the water supply module 120 are turned on to supply water and air to the premixing tank 131 according to the above steps of water supply and air supply, and bubble water is formed. When the bubble water is completed, if the user's operation instruction is still there, water can continue to be discharged, and if the user's operation instruction disappears, water will not be discharged.

[0039] As a specific embodiment of the present invention, the control method of the bubble water device 100 of this embodiment may further include: After the operation instruction disappears, when the operation instruction is received again within the sixth preset time, the sparkling water is directly taken from the premixing tank 131.

[0040] Specifically, when the user's operation instruction disappears, when the next user's water taking operation instruction is detected within a certain period of time, the sparkling water can be directly taken from the premix tank 131 without detection or waiting.

[0041] Of course, if the water level is too low or there is no water during this process, the bubble water in the premix tank 131 cannot be taken out, and the above process is repeated.

[0042] As another specific embodiment of the present invention, the control method of the bubble water device 100 of this embodiment may further include: After the operation instruction disappears, after a sixth preset time has passed, the liquid level information of the bubble water in the premix tank 131 is detected; When the liquid level of the bubble water is lower than the preset range, the gas supply module 110 and the water supply module 120 are re-controlled to provide carbon dioxide gas and water to the premixing tank 131 to form bubble water until the liquid level of the bubble water is higher than the preset range.

[0043] Specifically, since the user's operation instruction disappears for more than a certain period of time and there is no next user operation, the water level of the liquid needs to be detected. When the water level is lower than the lowest value of the preset range, it is necessary to provide water and carbon dioxide to the premix tank 131 in time to form bubble water for the convenience of subsequent users.

[0044] As a specific embodiment of the present invention, Figure 8 As shown, in step S200 of this embodiment, when the liquid level in the premixing tank 131 is lower than a preset range, the gas supply module 110 and the water supply module 120 are controlled to start providing carbon dioxide gas and water to the premixing tank 131 to form bubble water until the liquid level of the bubble water in the premixing tank 131 is higher than the preset range, and the step also includes: Step S400, detecting the ambient temperature of the premixing tank 131; Step S500, determining whether the ambient temperature is less than a preset temperature; if so, executing step S600, if not, executing step S700.

[0045] Step S600 , starting the gas supply module 110 and the water supply module 120 to provide carbon dioxide gas and water to the premix tank 131 to form bubble water.

[0046] Step S700, cooling the environment of the premixing tank 131 until the environment temperature is lower than a preset temperature, and then starting the air supply module 110 and the water supply module 120 to provide carbon dioxide and water to the premixing tank 131 to form bubble water.

[0047] Specifically, since the bubble water is sensitive to temperature, when the temperature is too high, a large amount of gas in the bubble water will overflow from the water, which will affect the taste of the bubble water on the one hand, and on the other hand, avoid the danger caused by excessive pressure in the premixing tank 131. Therefore, before making the bubble water, in this embodiment, the ambient temperature of the premixing tank 131 needs to be lowered to below the preset temperature, so as to ensure the taste of the bubble water and the safety of the premixing tank 131.

[0048] In addition, the premixing tank 131 of this embodiment can be a plastic tank or a metal tank, and a heat preservation layer is provided on the outside of the plastic tank or the metal tank, or the plastic tank or the metal tank is placed in a low temperature environment. Optionally, the premixing tank 131 of this embodiment is a double-layer metal vacuum tank, which not only ensures the strength of the premixing tank 131, but also can keep the premixing tank 131 warm.

[0049] As a specific embodiment of the present invention, this embodiment also provides a control device, which includes a memory and a processor. The memory stores a calculation program, and when the calculation program is executed by the processor, it is used to implement the control method of the above-mentioned bubble water device 100.

[0050] As a specific embodiment of the present invention, this embodiment also provides a refrigerator, which may include a bubble water device 100 and the above control device.

[0051] Specifically, the private bubble water device 100 can be placed in the refrigerator compartment or on the refrigerator door, and the water outlet can be set on the refrigerator door or the freezer door, so that the user can use the bubble water at any time, thereby improving the user experience.

[0052] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
