[0053] Carbonated water device - 100; Gas supply module - 110; Water supply module - 120; Premixing module - 130; Premixing tank - 131. Specific embodiments

[0054] In the description of this embodiment, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "top", "bottom", "inner", "outer", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0055] As a specific embodiment of the present invention, as Figure 1 and Figure 2 shown, this embodiment provides a control method for a carbonated water device. The carbonated water device 100 may include a gas supply module 110, a water supply module 120, and a premixing module 130. The gas supply module 110 provides carbon dioxide gas for the carbonated water, the water supply module 120 provides a water source for the carbonated water, and the premixing module 130 premixes the carbon dioxide gas of the gas supply module 110 and the water of the water supply module 120 to form carbonated water and stores the carbonated water; the premixing module 130 includes a premixing tank 131.

[0056] Specifically, as Figure 2 shown, the control method of the carbonated water device 100 in this embodiment may include:

[0057] Step S100, detecting the liquid level information of the carbonated water in the premixing tank 131 in real time;

[0058] Step S200, when the liquid level of the liquid in the premixing tank 131 is lower than the preset range, controlling the start of the gas supply module 110 and the water supply module 120 to provide carbon dioxide gas and water for the premixing tank 131 to form carbonated water until the liquid level of the carbonated water in the premixing tank 131 is higher than the preset range;

[0059] Step S300, in response to an operation instruction, extracting carbonated water from the premixing tank 131 for use.

[0060] Specifically, the control method of the sparkling water device 100 in this embodiment can maintain the liquid level of the sparkling water in the premixing tank 131 within a preset range according to the detected liquid level of the sparkling water in the premixing tank 131 and store it, so that when the user takes the sparkling water, the premixed sparkling water can be directly taken from the premixing tank 131 in real time without the user waiting, improving the user experience.

[0061] As a specific embodiment of the present invention, as Figure 3 shown, in step S200 of this embodiment, the steps of controlling the start of the gas supply module 110 and the water supply module 120 to provide carbon dioxide gas and water for the premixing tank 131 to form sparkling water include:

[0062] Step S210, exhausting the premixing tank 131;

[0063] Step S220, after the exhausting continues for the first preset time, the water supply module 120 supplies water into the premixing tank 131;

[0064] Step S230, when the liquid level of the liquid in the premixing tank 131 is higher than the preset range, the water supply module 120 stops supplying water to the premixing tank 131;

[0065] Step S240, after the water supply module 120 stops supplying water to the premixing tank 131 for the second preset time, close the exhaust valve.

[0066] Specifically, since the premixing tank 131 stores sparkling water, the air pressure in the premixing tank 131 will be relatively high. Before injecting water into the premixing tank 131, it is necessary to exhaust the premixing tank 131 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 also necessary to wait for the second preset time before closing the exhaust valve in order to allow the air pressure in the premixing tank 131 to reach stability before closing, which is beneficial to the subsequent other steps.

[0067] As a specific embodiment of the present invention, as Figure 4 shown, after step S240 of this embodiment closes the exhaust valve after the water supply module 120 stops supplying water to the premixing tank 131 for the second preset time, it may further include:

[0068] Step S250, start the gas supply module 110 to supplement carbon dioxide gas to the premixing tank 131 so that the gas in the premixing tank 131 forms sparkling water;

[0069] Step S260, alternately supplement carbon dioxide gas to the premixing tank 131 and exhaust the premixing tank 131 until the gas content in the sparkling water in the premixing tank 131 reaches the preset level.

[0070] Specifically, after the water replenishment of the premixing tank 131 is completed, it is necessary to replenish carbon dioxide gas to the premixing tank 131 through the gas supply module 110, and then mix carbon dioxide with water to form sparkling water. In addition, due to different requirements of users for the taste of sparkling water, the content of carbon dioxide in the sparkling water can be adjusted as needed to meet the needs of different users. In this embodiment, the content of gas in the sparkling water in the premixing tank 131 is adjusted by inflating and exhausting the premixing tank 131, which improves the user experience while ensuring safety.

[0071] Specifically, the grade of sparkling water can be classified according to the situation. For example, in the sparkling water device 100 of this embodiment, the grade of sparkling water is divided into three grades. When the user selects the first grade, the number of times of alternating inflation and exhaust needs to be n1 times. When the user selects the second grade, the number of times of alternating inflation and exhaust needs to be n2 times. When the user selects the third grade, the number of times of alternating inflation and exhaust needs to be n3 times. When the liquid level of the sparkling water in the premixing tank 131 is low and it is necessary to replenish water to form sparkling water, the grade of sparkling water can be preferably the first grade, the second grade or the third grade. When the user has the need to select the grade, the grade of the sparkling water can be adjusted for the user to drink.

[0072] As a specific embodiment of the present invention, as Figure 5 shown, the steps of step S260 of this embodiment for controlling the gas supply device to inflate the premixing tank 131 and controlling the exhaust valve to exhaust the premixing tank 131 alternately include:

[0073] Step S261, start the gas supply device to inflate the premixing tank 131 and then close it after a third preset time;

[0074] Step S262, exhaust the premixing tank 131 for a fourth preset time and then close it;

[0075] Step S263, repeat the above steps until the number of times matching the preset grade is reached and then end.

[0076] Specifically, when inflating and exhausting alternately in this embodiment, a certain period of time needs to be continued to ensure the effectiveness of inflation and exhaust. In addition, the time of inflation and exhaust, as well as the number of times of inflation and exhaust, determine the content of carbon dioxide in the sparkling water, and thus determine the taste of the sparkling water, which can be designed according to the actual situation.

[0077] As a specific embodiment of the present invention, as Figure 6 shown, the steps of step S300 of this embodiment for extracting sparkling water from the premixing tank 131 for use in response to an operation instruction include:

[0078] Step S310: In response to the operation instruction, exhaust the premixing tank 131 for a fifth preset time;

[0079] Step S320: Control the discharge of carbonated water from the premixing tank 131 until the operation instruction disappears;

[0080] Step S330: Control the premixing tank 131 to stop discharging carbonated water.

[0081] Specifically, in this embodiment, when receiving the instruction to take carbonated water, since the carbonated water stored in the premixing tank 131 has a relatively high internal pressure, it is necessary to first exhaust the gas in the premixing tank 131 before taking the carbonated water, so as to avoid the carbonated water flowing out too quickly due to the excessive air pressure in the premixing tank 131, which affects the user experience.

[0082] The fifth preset time in this embodiment can be designed according to the actual situation. Generally speaking, the fifth preset time is relatively short, which avoids the problem of poor user experience caused by the user waiting for too long.

[0083] 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, control the start of the gas supply module 110 and the water supply module 120 to provide carbon dioxide gas and water for the premixing tank 131 to form carbonated water until the liquid level of the carbonated water in the premixing tank 131 is higher than the preset range.

[0084] This process is specifically to ensure that the next user can use the carbonated water in time, thereby improving the user experience.

[0085] As another specific embodiment of the present invention, as Figure 7 shown, the steps of step S300 in this embodiment for controlling the extraction of carbonated water from the premixing tank 131 for use in response to the operation instruction include:

[0086] Step S340: In response to the operation instruction, exhaust the premixing tank 131 for a fifth preset time;

[0087] Step S350: Control the discharge of carbonated water from the premixing tank 131 until the liquid level in the premixing tank 131 is lower than the preset range;

[0088] Step S360: Control the premixing tank 131 to stop discharging carbonated water.

[0089] Specifically, before taking the sparkling water, since there is a relatively large amount of other substances in the premixing tank 131, it is necessary to exhaust the gas in the premixing tank 131 first to avoid the problem of too rapid outflow of the sparkling water. In addition, during the process of taking the sparkling water from the premixing tank 131, the liquid level of the sparkling water will continuously drop. When the user takes the sparkling water to a relatively low liquid level, the premixing tank 131 stops discharging the sparkling water. At this time, the operation interface of the user will flash to prompt the user that the liquid level of the sparkling water is too low and please wait for a while.

[0090] Specifically, when the premixing tank 131 stops discharging water, the gas supply module 110 and the water supply module 120 are started to supply water and gas to the premixing tank 131 according to the above steps of water supply and gas supply, and sparkling water is formed. When the sparkling water is completed, if the user's operation instruction still exists, the water can continue to be discharged. If the user's operation instruction disappears, the water will not be discharged.

[0091] As a specific embodiment of the present invention, the control method of the sparkling water device 100 of this embodiment may further include:

[0092] 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.

[0093] Specifically, when the user's operation instruction disappears, within a certain period of time, when the next user's water-taking operation instruction is detected, the sparkling water can be directly taken from the premixing tank 131 without detection or waiting.

[0094] Of course, during this process, if the water level is too low or there is no water, the sparkling water in the premixing tank 131 cannot be taken out, and the above process is repeated.

[0095] As another specific embodiment of the present invention, the control method of the sparkling water device 100 of this embodiment may further include:

[0096] After the operation instruction disappears, after exceeding the sixth preset time, start to detect the liquid level information of the sparkling water in the premixing tank 131;

[0097] When the liquid level of the sparkling water is lower than the preset range, re-control the gas supply module 110 and the water supply module 120 to provide carbon dioxide gas and water for the premixing tank 131 to form sparkling water until the liquid level of the sparkling water is higher than the preset range.

[0098] Specifically, since there is no next user operation after the user's operation instruction has disappeared for a certain period of time, it is necessary to detect the water level of the liquid at this time. When the water level is lower than the lowest value of the preset range, it is necessary to timely provide water and carbon dioxide for the premixing tank 131 to form sparkling water for the subsequent use of the user.

[0099] As a specific embodiment of the present invention, as Figure 8 shown, before the step of step S200 in this embodiment controls the start of the gas supply module 110 and the water supply module 120 to supply carbon dioxide gas and water to the premixing tank 131 to form sparkling water until the liquid level of the sparkling water in the premixing tank 131 is higher than the preset range, it further includes:

[0100] Step S400, detecting the ambient temperature of the premixing tank 131;

[0101] Step S500, determining whether the ambient temperature is less than the preset temperature; if so, execute step S600, if not, execute step S700.

[0102] Step S600, starting the gas supply module 110 and the water supply module 120 to supply carbon dioxide gas and water to the premixing tank 131 to form sparkling water.

[0103] Step S700, cooling the environment where the premixing tank 131 is located until the ambient temperature is lower than the preset temperature, and then starting the gas supply module 110 and the water supply module 120 to supply carbon dioxide and water to the premixing tank 131 to form sparkling water.

[0104] Specifically, since sparkling water is relatively sensitive to temperature, when the temperature is too high, a large amount of gas in the sparkling water overflows from the water. On the one hand, it affects the taste of the sparkling water, and on the other hand, it is to avoid the danger caused by too high air pressure in the premixing tank 131. Therefore, before making sparkling water in this embodiment, it is also necessary to lower the ambient temperature of the premixing tank 131 below the preset temperature, thereby ensuring the taste of the sparkling water and the safety of the premixing tank 131.

[0105] In addition, the premixing tank 131 in this embodiment can be a plastic tank or a metal tank, and a heat insulation layer is provided outside 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 in this embodiment is a double-layer metal vacuum tank, which not only ensures the strength of the premixing tank 131 but also can insulate the premixing tank 131.

[0106] 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 sparkling water device 100.

[0107] As a specific embodiment of the present invention, this embodiment also provides a refrigerator, which may include the sparkling water device 100 and the above control device.

[0108] Specifically, the private sparkling water device 100 of the present invention can be placed in the refrigerating chamber of the refrigerator or on the refrigerating door body, and the water outlet can be arranged on the refrigerating door body or the freezing door body of the refrigerator, so that users can access sparkling water at any time, enhancing the user experience.
