[0047] In the description of this embodiment, it should be understood that the orientation or positional relationship indicated by the terms "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.

[0048] As a specific embodiment of the present invention, as Figures 1 - 3 shown, this embodiment provides a sparkling water device 100, which may include a gas supply module 200, a water supply module 300, a premixing module 400, and a control device (not shown in the figure). Among them, the gas supply module 200 is used to provide carbon dioxide gas. The water supply module 300 is used to provide a water source. The premixing module 400 is used to premix the carbon dioxide gas from the gas supply module 200 and the water from the water supply module 300 to form sparkling water, and store the sparkling water. The control device is used to control, according to instructions, the gas supply module 200 to supply gas to the premixing module 400, the water supply module 300 to supply water to the premixing module 400, and control the premixing module 400 to form sparkling water and discharge water in real time.

[0049] Specifically, the sparkling water device 100 of this embodiment can mix the carbon dioxide gas from the gas supply module 200 and the water from the water supply module 300 through the premixing module 400 to form sparkling water and store it. When the user needs to obtain sparkling water, directly obtain the sparkling water from the premixing module 400, without configuring sparkling water on site, saving the user's waiting time and improving the user's experience.

[0050] Specifically, the control device of this embodiment can control the actions of all internal electric components, such as solenoid valves, water pumps, air pumps, etc. The control steps and timing can write the control logic into the internal according to needs.

[0051] As a specific embodiment of the present invention, the premixing module 400 of this embodiment may include a premixing tank 410 and a water level detector 420, wherein the water level detector 420 is located inside the premixing tank 410. The water level detector 420 is used to detect the liquid level information of the sparkling water in the premixing tank 410 and transmit the liquid level information to the control device.

[0052] Specifically, the water level detector 420 of this embodiment may include a high water level probe 421 and a low water level probe 422. The high water level probe 421 is used to detect the highest water level in the premixing tank 410, and the low water level probe 422 is used to detect the lowest water level in the premixing tank 410.

[0053] As a specific embodiment of the present invention, the premixing tank 410 of this embodiment includes a tank body and a heat preservation component, and the heat preservation component ensures that the sparkling water in the metal tank remains within a preset temperature range. The tank body can be a metal tank body or a plastic tank body.

[0054] Specifically, when the bubble water is in a high-temperature environment, the gas inside is likely to overflow. Therefore, in this embodiment, the premixing tank 410 is provided with a heat-insulating component at the tank body to insulate the tank body, so that the temperature inside the premixing tank 410 is maintained in a low temperature range, avoiding a large amount of gas overflowing from the premixing tank 410. Specifically, the heat-insulating component in this embodiment can be a heat-insulating layer provided inside and outside the tank body, or the tank body can be placed in an environment with a constant temperature.

[0055] As another specific embodiment of the present invention, the premixing tank 410 in this embodiment is a double-layer metal vacuum tank. On the one hand, this double-layer metal vacuum tank can ensure the strength of the tank body, and on the other hand, it can insulate the inside of the tank body to ensure that the temperature inside the tank body is maintained at a relatively constant temperature.

[0056] As a specific embodiment of the present invention, the water supply module 300 in this embodiment may include a water pipe 310 and a water pump 320. Among them, one end of the water pipe 310 is connected to an external water source (not shown in the figure) or a water storage tank 330, and the other end is connected to the premixing tank 410. The water pump 320 is arranged on the water pipe 310. The water pump 320 is electrically connected to the control device. When the water level detector 420 detects that the liquid level of the bubble water is lower than the preset range, the control device controls the water pump 320 to start, and when the water level detector 420 detects that the liquid level of the bubble water is higher than the preset range, the control device controls the water pump 320 to close, so as to keep the liquid level in the premixing tank 410 within the preset range.

[0057] Specifically, generally speaking, the water supply module 300 can use the purified water stored in the water storage tank 330 or be directly connected to tap water. Of course, when directly connected to tap water, a purifier will be additionally provided to ensure that the water source can be directly drunk.

[0058] The water pump 320 in the water supply module 300 can pump the water source in the water storage tank 330 or from the outside into the premixing tank 410. Since the liquid in the premixing tank 410 cannot be infinitely much or infinitely little, the control device will combine with the water level detector 420 to control the start and stop of the water pump 320, thereby ensuring that the water level in the premixing tank 410 is maintained within the preset range. Specifically, when the low water level probe 422 detects that the liquid level in the premixing tank 410 is lower than the minimum value of the preset range, the control device controls the water pump 320 to add water to the premixing tank 410, so that the water level in the premixing tank 410 gradually rises. When the water level in the premixing pipe gradually rises to the high water level probe 421 detecting that the water level is higher than the maximum value of the preset range, the control device controls the water pump 320 to stop adding water to the premixing tank 410.

[0059] As a specific embodiment of the present invention, the gas supply module 200 of this embodiment may include a gas tank 210, a gas pipe 220, and a gas pump 230. Among them, the gas tank 210 is used to store carbon dioxide gas. The gas pipe 220 is connected between the gas tank 210 and the premixing tank 410. The gas pump 230 is arranged at the gas tank 210 or the gas pipe 220 and is electrically connected to the control device. After the water supply module 300 supplies water to the premixing tank 410, the control device controls the gas pump 230 to start to inflate the premixing tank 410 to form bubble water.

[0060] Specifically, after the gas supply module 200 of this embodiment inputs additional water into the premixing tank 410, the gas pump 230 starts to input the gas in the gas tank 210 into the premixing tank 410 and mixes it with the water in the premixing tank 410 to form bubble water.

[0061] As a specific embodiment of the present invention, the premixing module 400 of this embodiment may further include an exhaust valve 430. The exhaust valve 430 is electrically connected to the control device. The control device controls the exhaust valve 430 to open for a first preset time before the water pump 320 supplies water to the premixing tank 410, and controls the exhaust valve 430 to close after the water pump 320 finishes supplying water to the premixing tank 410 and after a second preset time.

[0062] Specifically, since the premixing tank 410 is a closed tank and the internal pressure is relatively high due to the stored bubble water in the tank. When water needs to be transported into the tank, if no exhaust is carried out, it will cause the situation that the water cannot be transported into the tank. Therefore, in this embodiment, the exhaust valve 430 needs to be opened for a first preset time before transporting water into the premixing tank 410. After the internal gas is released, water is replenished into the premixing tank 410. Since the water will also continuously occupy the internal volume of the premixing tank 410, the exhaust valve 430 is closed after the water is replenished.

[0063] As a specific embodiment of the present invention, the bubble water of this embodiment may include different bubble levels. The control device controls the gas pump 230 and the exhaust valve 430 to inflate and exhaust the premixing tank 410 respectively according to the level of the bubble water; among them, under different levels, the number of times of inflation and exhaust repetition is different.

[0064] Specifically, since users have different requirements for the taste of sparkling water, the sparkling water in the sparkling water device 100 of this embodiment is provided with multiple levels for users to choose from. In sparkling water of different levels, the carbon dioxide content is different. And the gas content in the sparkling water is obtained by continuously pumping air into and exhausting air from the premixing tank 410. In this embodiment, the levels of the sparkling water can be divided into three levels. The number of times of pumping air and exhausting air for the first level is n1 times, the number of times of pumping air and exhausting air for the second level is n2 times, and the number of times of pumping air and exhausting air for the third level is n3 times. Generally, when no user selects the sparkling water level, the second level is the default. The sparkling water stored in the premixing tank 410 is also pumped air, exhausted air and stored according to the gas content of the second level.

[0065] As a specific embodiment of the present invention, the process of each inflation and exhaust cycle in this embodiment may include controlling the opening of the air pump 230 and closing it after a third preset time, controlling the opening of the exhaust valve 430, and closing it after a fourth preset time.

[0066] Specifically, the inflation time and exhaust time in this embodiment can be set according to the actual situation. Together with the number of repetitions of inflation and exhaust, this time determines the gas content in the sparkling water.

[0067] As a specific embodiment of the present invention, the sparkling water device 100 of this embodiment may further include a water outlet module 500. The water outlet module 500 may include a water outlet pipe 510 communicating with the premixing tank 410, a driving device, and a water outlet valve 520 located at the water outlet pipe 510. When the control device receives the water outlet button instruction, it controls the opening of the exhaust valve 430 and closes it after a fifth preset time, controls the opening of the water outlet valve 520 and the driving device, starts to discharge sparkling water, and controls the closing of the water outlet valve 520 and the driving device when the water outlet button instruction disappears.

[0068] Specifically, the water outlet module 500 discharges the sparkling water in the premixing tank 410 through the driving device for the customer to use. Before discharging water, the exhaust valve 430 is first opened for exhaust to avoid the problem of too fast water flow due to excessive air pressure in the premixing tank 410, which may cause a poor user experience.

[0069] As a specific embodiment of the present invention, the control device of this embodiment is further configured to, during the process of discharging sparkling water, receive the water level information of the water level detector 420 in real time, and control the closing of the water outlet valve 520 and the driving device when the water level information shows that the water level of the sparkling water is lower than the preset range, and control the exhaust valve 430, the air pump 230 and the water pump 320 to form sparkling water of a predetermined level in the premixing tank 410 until the liquid level of the sparkling water is higher than the preset range.

[0070] Specifically, in this embodiment, when a water intake instruction is received, if the water level continuously drops during the water intake process and drops below the minimum value of the preset range, it indicates that the water level is already low at this time and bubble water cannot be obtained anymore. At this time, the water outlet valve 520 and the driving device will be directly closed. Then, by controlling the exhaust valve 430, the air pump 230, and the water pump 320, water and carbon dioxide gas are further mixed in the pre-mixing tank 410 to form bubble water until the liquid level is higher than the maximum value of the preset range. If the water intake instruction still exists at this time, the water outlet valve 520 and the driving device will be opened to produce bubble water. If the water intake instruction disappears, no bubble water will be produced.

[0071] As one of the embodiments, as Figure 1 and Figure 2 shown, the driving device of this embodiment may include an air inflation pump 530. The air inflation pump 530 is connected to the pre-mixing tank 410 through a pipeline to inflate the pre-mixing tank 410 when it is necessary to take bubble water from the pre-mixing tank 410, so as to press the bubble water in the pre-mixing tank 410 out through the water outlet pipe 510.

[0072] When the driving device is the air inflation pump 530, the air inflation pump 530 is connected to the pre-mixing tank 410 through an air pipe 220 to inflate the pre-mixing tank 410 and press out the bubble water in the pre-mixing tank 410.

[0073] As another embodiment, as Figure 2 the driving device of this embodiment is a water pump 540. The water pump 540 is arranged at the water outlet pipe 510 to turn on the water pump 540 when it is necessary to take bubble water from the pre-mixing tank 410, and then extract the bubble water from the pre-mixing tank 410.

[0074] As a specific embodiment of the present invention, the pre-mixing module 400 of this embodiment may further include at least one pressure relief valve 440. The pressure relief valve 440 is used to open when the pressure in the pre-mixing tank 410 is greater than the preset pressure.

[0075] Specifically, the pressure relief valve 440 of this embodiment includes one or more. The main function of the pressure relief valve 440 is to automatically relieve pressure when the air pressure in the pre-mixing tank 410 is greater than the preset air pressure value, avoid excessive air pressure in the pre-mixing tank 410, improve the service life of the pre-mixing tank 410, and improve the safety performance of the pre-mixing tank 410. Preferably, the pressure relief valve 440 of this embodiment includes two, one is a 6-kilogram pressure relief valve, and the other is an 8-kilogram pressure relief valve.

[0076] As a specific embodiment of the present invention, the bubble water device 100 of this embodiment may further include a bracket 600. The bracket 600 is used to install and support the pre-mixing module 400 and the air supply module 200.

[0077] Specifically, the bracket 600 may include two mounting positions for mounting the premixing module 400 and the gas supply module 200 respectively. The two mounting positions are close to each other, and the bracket 600 is also provided with support structures and avoidance structures for pipelines, valves, etc., which can be freely designed according to the actual structure and position.

[0078] As a specific embodiment of the present invention, this embodiment further provides a refrigerator, which includes the above-mentioned sparkling water device 100.

[0079] The refrigerator equipped with the sparkling water device 100 can access sparkling water at any time, improving the user experience.
