Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a bubble water device and a refrigerator. Background Technology

[0002] A sparkling water device is a machine that can convert ordinary drinking water into sparkling water rich in bubbles. It typically consists of an air pump, an air cylinder, a pressure regulator, a water container, and related connecting parts. Its working principle is to use the air pump to inject high-pressure gas (usually carbon dioxide) into the water in the water container through the pressure regulator. The gas dissolves in the water under pressure, thus forming sparkling water with abundant bubbles. Some sparkling water devices also feature adjustable pressure, allowing users to adjust the amount of bubbles to their liking to meet different taste preferences. Currently, the inclusion of sparkling water functionality in refrigerators offers users a completely new experience.

[0003] In sparkling water devices, carbon dioxide is typically stored separately in a gas cylinder. When sparkling water is needed, the device manually or mechanically releases the carbon dioxide gas from the cylinder into a water container, where it mixes with the water to form sparkling water. Current technology makes it difficult to control the amount of carbonation during sparkling water production, resulting in a rather monotonous taste. Furthermore, dispensing sparkling water is cumbersome for users, involves long waiting times, is inefficient, and some sparkling water may leak out with the gas during depressurization, leading to a poor user experience.

Detailed Implementation

[0052] In the description of this embodiment, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0053] As a specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, this embodiment provides a sparkling water device 100, which may include a premixing module 200 and a gas supply module 300. The premixing module 200 is used to premix carbon dioxide gas and water to form sparkling water and to store the sparkling water. The gas supply module 300 may include a gas cylinder 310 and an aerator 320. The gas cylinder 310 is used to store carbon dioxide gas. The aerator 320 is disposed above the gas cylinder 310 and is used to control the opening or closing of the gas cylinder 310, thereby supplying or stopping the gas supply to the premixing module 200.

[0054] Specifically, in this embodiment, an air pumping device 320 is installed above the gas cylinder 310. The air pumping device 320 opens or closes the gas cylinder 310 to supply gas to the premix module 200, thereby realizing automatic mechanical control of the opening and closing of the gas cylinder 310, improving the gas supply efficiency, and thus improving the efficiency of generating sparkling water.

[0055] As a specific embodiment of this utility model, such as Figures 3-5 As shown, the top of the gas cylinder 310 in this embodiment may include a switch mechanism 311. The air pumping device 320 may include a push rod 321. The bottom of the push rod 321 abuts against the switch mechanism 311, and the push rod 321 moves up and down in a controlled manner, thereby pushing the push rod 321 to open or close the gas cylinder 310.

[0056] Specifically, in this embodiment, the switch mechanism 311 at the top of the gas cylinder 310 can abut against the push rod 321, and the switch mechanism 311 can be opened or closed under the push of the push rod 321, thereby allowing the gas in the gas cylinder 310 to flow out controllably from the switch mechanism 311.

[0057] More specifically, the air pumping device 320 of this embodiment may further include a housing 322 and a piston 323. The housing 322 is detachably connected to the top of the gas cylinder 310, and the housing 322 and the gas cylinder 310 form a receiving space. A push rod 321 is disposed within the receiving space. The piston 323 is disposed within the receiving space, and the piston 323 moves up and down controllably within the receiving space, thereby pushing the push rod 321 to move up and down.

[0058] Specifically, in this embodiment, the piston 323 moves to push the push rod 321 to move, and the push rod 321 then pushes the switching mechanism 311 of the gas cylinder 310 to move, thereby releasing the gas inside the gas cylinder 310.

[0059] Specifically, a sealing ring 324 is provided between the piston 323 and the inner wall of the housing 322 to prevent the gas above the piston 323 from flowing with the gas below the piston 323.

[0060] Since the gas coming out of the gas cylinder 310 is located below the piston 323, in order to prevent the gas coming out of the gas cylinder 310 from leaking upwards after passing through the piston 323, a sealing ring 324 is provided between the piston 323 and the inner wall of the housing 322 in this embodiment.

[0061] As a specific embodiment of this utility model, the housing 322 may also be provided with an air inlet 3221 and an exhaust outlet 3222. The air inlet 3221 is connected to a first air pump 325 via an air pipe. When the first air pump 325 is activated, it fills the space between the top of the housing 322 and the piston 323 with air, pushing the piston 323 downwards and thus opening the switching mechanism 311 of the gas cylinder 310 to release carbon dioxide. After the gas cylinder 310 has completed the release of carbon dioxide, the gas between the piston 323 and the top of the housing 322 is discharged through the exhaust outlet 3222.

[0062] Specifically, in this embodiment, an external first air pump 325 supplies air to the upper part of the piston 323 and the housing 322. At this time, the air pressure in the space between the piston 323 and the upper part of the housing 322 increases, pushing the piston 323 downwards. The piston 323 then pushes the push rod 321 downwards, thereby pushing the switching mechanism 311 to open the gas cylinder 310 to release air. After the release is complete, the first air pump 325 is turned off, and the gas in the upper part of the piston 323 and the housing 322 is continuously discharged through the exhaust port 3222. The piston 323 moves upwards, and the push rod 321 moves upwards, thereby causing the switching mechanism 311 to close the gas cylinder 310.

[0063] A solenoid valve can be installed in the air pipe between the first air pump 325 and the air inlet 3221 to control the flow of gas into the housing 322. Similarly, a solenoid valve is installed at the exhaust port 3222 to control the flow of gas out. Some of the solenoid valve structures in the attached drawings have been simplified for clarity in the final drawings.

[0064] Since the space above piston 323 requires air pressure to drive piston 323 to move, sealing ring 324 also prevents gas above piston 323 from leaking downwards.

[0065] As a specific embodiment of the present invention, the air pumping device 320 of this embodiment may further include an elastic element 326. The elastic element 326 abuts against the bottom inner wall of the housing 322 and the bottom of the piston 323, so that when the first air pump 325 stops inflating the inside of the housing 322, the elastic element 326 pushes the piston 323 upward to expel the gas inside the housing 322.

[0066] Specifically, after the first air pump 325 stops supplying air to the inside of the housing 322, the gas inside the housing 322 is discharged through the exhaust port 3222. After the pressure above the piston 323 decreases, the switching mechanism 311 closes due to the pressure of the gas cylinder 310, and the push rod 321 will also move upward accordingly. The piston 323 moves upward under the elastic force of the elastic element 326 until it abuts against the upper side wall of the housing 322.

[0067] Specifically, the elastic element 326 in this embodiment can be a spring or other resilient component, such as an elastic sponge. In this embodiment, the elastic element 326 is preferably a spring.

[0068] As a specific embodiment of this utility model, the housing 322 may further include a positioning post 327, which extends upward from the bottom wall of the housing 322, and an elastic member 326 is sleeved on the positioning post 327. A through hole 3271 communicating with the receiving space and the gas cylinder 310 is provided in the middle of the positioning post 327. A push rod 321 is provided inside the through hole 3271. The piston 323 may include an abutment portion 3231, which extends from outside the through hole 3271 into the through hole 3271 and abuts against the push rod 321.

[0069] Specifically, this embodiment may include, from top to bottom, a piston 323, a contact portion 3231 of the piston 323, a push rod 321, and a switching mechanism 311. A positioning post 327 extends upward from the bottom of the housing 322, and the contact portion 3231 extends downward from above the through hole 3271 of the housing 322 into the through hole 3271. The push rod 321 is disposed within the through hole 3271, with its upper end abutting against the contact portion 3231 and its lower end abutting against the switching mechanism 311. A spring is sleeved on the outside of the positioning post 327, which can push the piston 323 ring upward, thereby helping the piston 323 ring to return to its original position. Through the positioning post 327 and the through hole 3271 at the positioning post 327, the spring, push rod 321, and piston 323 can be positioned, preventing misalignment of the spring, push rod 321, and piston 323 from causing unstable movement.

[0070] As a specific embodiment of the present utility model, the outer side wall of the push rod 321 of this embodiment is provided with at least one groove, and each groove is provided with a rubber ring 328. When the push rod 321 is placed in the through hole, the rubber ring 328 abuts against the side wall of the through hole 3271.

[0071] Specifically, in this embodiment, at least one groove is provided on the outer side wall of the push rod 321, and each groove is annular around the axial direction of the outer side wall of the push rod 321. A rubber ring 328 can be provided at each groove to seal the space below and above the push rod 321.

[0072] As a specific embodiment of this utility model, the housing 322 of this embodiment may also include an outlet 3223. When the push rod 321 pushes the switch mechanism 311 to open the gas cylinder 310, the carbon dioxide in the gas cylinder 310 flows out from the outlet 3223.

[0073] Specifically, the outlet 3223 is connected to the premix module 200 via a gas pipe, allowing carbon dioxide gas from the gas cylinder 310 to flow from the outlet 3223 and the gas pipe into the premix module 200.

[0074] As a specific embodiment of this utility model, such as Figure 6 and Figure 7 As shown, the premixing module 200 in this embodiment may include a premixing tank 210. The premixing tank 210 is used to receive carbon dioxide gas from the gas supply module 300 and external water, mix them in the premixing tank 210 to form sparkling water, and store the sparkling water. An air inlet valve 221 may also be provided at the premixing tank 210. The air outlet 3223 is connected to the air inlet valve 221 through an air pipe, so that the carbon dioxide gas in the gas cylinder 310 enters the premixing tank 210 after passing through the air pipe and the air inlet valve 221.

[0075] Specifically, the premixing tank 210 in this embodiment includes a cover 220, which is sealed to the tank body. An air inlet valve 221 is provided at the cover 220. Gas is introduced into the premixing tank 210 after being connected to the air outlet 3223 via an air pipe. The air inlet valve 221 not only connects to the air pipe but also controls the air intake.

[0076] Specifically, the premixing tank 210 is equipped with an exhaust valve 222 at its cover 220 to release gas from the premixing tank 210. Since the premixing tank 210 is a sealed device, when water or other gases need to be added, the exhaust valve 222 can be used to release the gas for easy addition. Furthermore, since the premixing tank 210 contains sparkling water, the concentration of the sparkling water needs to be maintained through continuous alternation of air intake and exhaust to achieve a specific concentration.

[0077] Specifically, the sparkling water device 100 of this embodiment may further include an exhaust pipe 230, which is connected to an exhaust valve 222 so that when the exhaust valve 222 is opened, the gas in the premix tank 210 is discharged through the exhaust pipe 230. Specifically, a silencer 240 is provided at the exhaust pipe 230 to eliminate the sound of the exhaust pipe 230.

[0078] Because the gas pressure inside the premix tank 210 is relatively high, the gas noise is also relatively loud when the exhaust valve 222 exhausts. Therefore, the muffler 240 on the exhaust pipe 230 is used to reduce the noise and improve the user experience.

[0079] In addition, a water receiving tray 250 is provided in the sparkling water device 100. The water receiving tray 250 is located at the end of the exhaust pipe 230 to receive the liquid discharged from the exhaust pipe 230.

[0080] Since the premix tank 210 contains sparkling water, when the exhaust valve 222 and exhaust pipe 230 are venting, water vapor will inevitably be present in the gas. When the water vapor encounters the exhaust pipe 230, condensation will occur and then be discharged. Therefore, the drip tray 250 is needed to catch the condensation to prevent it from flowing freely and affecting the user experience.

[0081] Specifically, in this embodiment, at least one pressure relief valve 223 is also provided at the cover 220 of the premixing tank 210 to open when the pressure inside the premixing tank 210 exceeds a preset value. The number of pressure relief valves 223 at the premixing tank 210 can be one or more. The pressure relief valves 223 are designed according to the pressure value that the premixing tank 210 can withstand, to prevent excessive pressure inside the premixing tank 210 and ensure the safety of the premixing tank 210.

[0082] As a specific embodiment of the present invention, the sparkling water device 100 of this embodiment may further include a water supply device (not shown in the figure), wherein a water inlet is provided at the premix tank 210, and the water inlet is connected to the water supply device through a water pipe to receive water provided by the water supply device.

[0083] The main function of the water supply device is to provide water to the premixing tank 210, which may include a water tank, water pipes, and a water pump. The water tank can be pre-stored with purified water. Alternatively, it can be directly connected to an external water source via water pipes. When directly connected to an external water source, a purification device can be installed at the water pipe to make the water directly drinkable.

[0084] Specifically, in this embodiment, a water inlet 225 is provided on the cover 220. After the water supply device is connected to the water inlet 225 through a water pipe, water from the outside is injected into the premix tank 210 through the water inlet 225.

[0085] Specifically, in this embodiment, a water level detector 226 is also provided inside the premixing tank. The water level detector 226 detects the water level in the premixing tank 210, thereby replenishing the premixing tank 210 with water when the water level is too low, or stopping water replenishment when the water level is too high. As a specific embodiment of this utility model, the sparkling water device 100 of this embodiment may also include a drainage device, which may include a drain pipe and a driving device, through which the sparkling water in the premixing tank 210 is discharged for use.

[0086] Specifically, a drain outlet 260 is provided at the cover 220 of the premix tank 210; the drain device is connected to the drain outlet 260 through a drain pipe. When the sparkling water device 100 receives a water-taking instruction, the drain device will directly extract sparkling water from the premix tank 210 for the user to drink.

[0087] As a specific embodiment of the present invention, the driving device of this embodiment may include a second air pump 330. The second air pump 330 is connected to the water inlet 225 at the cover 220 through an air pipe, so that the second air pump 330 can input gas into the premix tank 210 through the air pipe, so that the liquid in the premix tank 210 can be discharged through the drain pipe.

[0088] In actual use, a solenoid valve needs to be installed at each trachea to control the flow or stop of gas in the trachea.

[0089] In this embodiment, when the first air pump 325 and the second air pump 330 that inflate the air pumping device 320 are two separate air pumps, such as Figure 8 As shown, a separate solenoid valve can be installed in the air pipe where each air pump is located to control the flow of gas.

[0090] In another specific embodiment, the second air pump 330 and the first air pump 325 are the same air pump. With the same air pump, the air pipes form a main pipe 331 and two branch pipes 332, and a three-way valve (e.g., ...) is installed at the bifurcation point of the main pipe 331 and the branch pipes 332. Figure 9 (as shown) or a solenoid valve can be installed at each of the two branch pipes (e.g. Figure 10 (As shown).

[0091] As a specific embodiment of the present invention, this embodiment also provides a refrigerator, which may include the bubble water device 100 mentioned above.

[0092] The refrigerator can be equipped with a sparkling water device 100. The premix tank 210 first mixes carbon dioxide gas with water to form sparkling water. When needed, the sparkling water can be directly extracted from the premix tank 210 without the user having to wait.

[0093] Specifically, taking the example of placing the sparkling water device 100 inside a refrigerator, the principle of the entire sparkling water device 100 will be explained in detail.

[0094] When gas needs to be supplied to the premix tank 210, the first air pump 325 first pumps air into the air pumping device 320. The gas enters the housing 322 through the air inlet 3221, pushing the piston 323 downward. The piston 323 then pushes the push rod 321 downward. The push rod 321 pushes the switch mechanism 311 above the gas cylinder 310 to open the gas cylinder 310, and the carbon dioxide gas in the gas cylinder 310 is discharged, entering the premix tank 210 through the air outlet of the air pumping device 320 and the air pipe. After the gas in the gas cylinder 310 is discharged, the first air pump 325 stops working, the solenoid valve at the air pipe connected to the exhaust nozzle 3222 opens, and the gas above the piston 323 is continuously discharged from the exhaust nozzle 3222. Under the elastic force of the spring, the piston 323 continuously moves upward, the push rod 321 moves upward, the switch mechanism 311 of the gas cylinder 310 closes, and the gas cylinder 310 stops supplying gas.

[0095] When it is necessary to vent the premix tank 210, the vent valve 222 can be opened to vent the water. Venting the water is also necessary when adding water to the premix tank 210 or when forming bubble water.

[0096] When a water-taking instruction is received and sparkling water needs to be taken from the premix tank 210, the second air pump can be used to inflate the premix tank 210 with air, or the water pump can be used to directly draw sparkling water from the premix tank 210. The sparkling water in the premix tank 210 is then discharged through the drainage device for user use.

[0097] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of 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 such other variations or modifications.
