Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a bubble water device and a refrigerator. Background Art

[0002] A sparkling water device is a device that can convert ordinary drinking water into sparkling water rich in bubbles. It is usually composed of an air pump, a gas cylinder, a pressure regulator, a water container and related connecting parts. Its working principle is to use an air pump to inject high-pressure gas (usually carbon dioxide) into the water in the water container through a pressure regulator, so that the gas dissolves in the water under pressure, thereby forming sparkling water with rich bubbles. Some sparkling water devices are also equipped with an adjustable pressure function, and users can adjust the richness of bubbles according to personal preferences to meet different taste requirements. At present, the function of equipped with sparkling water in refrigerators has brought users a brand new experience.

[0003] The carbon dioxide in the bubble water device is usually loaded separately from the gas cylinder. When you need to take the bubble water, you need to wait for the device to release the carbon dioxide gas in the gas cylinder into the water container manually or mechanically, and then mix it with water to form bubble water. The existing technology is difficult to control the amount of gas when making bubble water, and the taste is relatively simple. When taking the bubble water, the user's operation is cumbersome, the waiting time is long, the efficiency is low, and when the pressure is relieved, some of the bubble water will overflow from the gas path with the gas, resulting in a poor experience.

DETAILED DESCRIPTION

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

[0053] As a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, this embodiment provides a bubble 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 bubble water, and store the bubble water. The gas supply module 300 may include a gas cylinder 310 and a gas pumping device 320, and the gas cylinder 310 is used to store carbon dioxide gas. The gas pumping device 320 is arranged above the gas cylinder 310, and is used to control the opening or closing of the gas cylinder 310, thereby supplying gas to the premixing module 200 or stopping the gas supply.

[0054] Specifically, this embodiment sets an aerating device 320 above the gas cylinder 310, and uses the aerating device 320 to open or close the gas cylinder 310 and supply gas to the premixing module 200, thereby realizing mechanical automatic control of the opening and closing of the gas cylinder 310, improving the gas supply efficiency, and thus improving the efficiency of producing bubble water.

[0055] As a specific embodiment of the present invention, Figure 3-Figure 5 As shown, the top of the gas cylinder 310 of this embodiment may include a switch mechanism 311. The inflating 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 to push the push rod 321 to open or close the gas cylinder 310.

[0056] Specifically, the switch mechanism 311 at the top of the gas cylinder 310 of this embodiment can abut against the top rod 321, and the switch mechanism 311 is opened or closed under the push of the top rod 321, so that the gas in the gas cylinder 310 can flow out from the switch mechanism 311 in a controllable manner.

[0057] More specifically, the inflating 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. The push rod 321 is disposed in the receiving space. The piston 323 is disposed in the receiving space, and the piston 323 is controlled to move up and down in 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 pushes the switch mechanism 311 of the gas cylinder 310 to move, thereby releasing the gas in 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 from the gas cylinder 310 is located below the piston 323 , in order to prevent the gas from the gas cylinder 310 from leaking upward 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 the present invention, the housing 322 of this embodiment may also be provided with an air inlet nozzle 3221 and an air outlet nozzle 3222. The air inlet nozzle 3221 is connected to the first air pump 325 through an air pipe, and when the first air pump 325 is started, the space between the top of the housing 322 and the piston 323 is inflated to push the piston 323 downward, thereby pushing the switch mechanism 311 of the gas cylinder 310 to release carbon dioxide. After the gas cylinder 310 completes the release of carbon dioxide, the gas between the piston 323 and the top of the housing 322 is discharged by the air outlet nozzle 3222.

[0062] Specifically, in this embodiment, the piston 323 and the upper part of the housing 322 are ventilated by the first air pump 325 from the outside. At this time, the air pressure in the space above the piston 323 and the housing 322 increases, pushing the piston 323 to move downward, and the piston 323 pushes the push rod 321 to move downward, thereby pushing the switch mechanism 311 to open the gas cylinder 310 to deflate. After deflation is completed, the first air pump 325 is turned off, and the gas above the piston 323 and the housing 322 is continuously discharged from the exhaust nozzle 3222, the piston 323 moves upward, and the push rod 321 moves upward, thereby causing the switch mechanism 311 to close the gas cylinder 310.

[0063] A solenoid valve may be provided at the air pipe between the first air pump 325 and the air inlet nozzle 3221 to control the flow of gas into the housing 322. Of course, a solenoid valve is also provided at the exhaust nozzle 3222 to control the outflow of gas. Some drawings simplify the structure of some solenoid valves for a clearer final drawing.

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

[0065] As a specific embodiment of the present invention, the inflation device 320 of this embodiment may further include an elastic member 326, which abuts between the bottom inner wall of the shell 322 and the bottom of the piston 323, so that when the first air pump 325 stops inflating the interior of the shell 322, the elastic member 326 pushes the piston 323 to move upward, thereby discharging the gas in the shell 322.

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

[0067] Specifically, the elastic member 326 of this embodiment can be a spring or other components that can rebound, such as an elastic sponge, etc. The elastic member 326 of this embodiment is preferably a spring.

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

[0069] Specifically, this embodiment may include a piston 323, an abutment portion 3231 of the piston 323, a push rod 321 and a switch mechanism 311 from top to bottom. The positioning column 327 extends upward from the bottom of the housing 322, the abutment portion 3231 extends downward from the top of the through hole 3271 of the housing 322 to the inside of the through hole 3271, and the push rod 321 is arranged in the through hole 3271, the upper end of the push rod 321 abuts against the abutment portion 3231, and the lower end abuts against the switch mechanism 311. The spring is sleeved outside the positioning column 327, which can push the piston 323 upward, thereby helping the piston 323 to reset. The spring, the push rod 321 and the piston 323 can be positioned through the positioning column 327 and the through hole 3271 at the positioning column 327 to avoid the misalignment of the spring, the push rod 321 and the piston 323 causing unstable movement.

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

[0071] Specifically, in the at least one groove provided on the outer side wall of the push rod 321 of this embodiment, 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, and the rubber ring 328 is used to seal the space below and above the push rod 321.

[0072] As a specific embodiment of the present invention, the shell 322 of this embodiment may also include a gas outlet nozzle 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 gas outlet nozzle 3223.

[0073] Specifically, the gas outlet nozzle 3223 is connected to the premixing module 200 through an air pipe, so that the carbon dioxide gas in the gas cylinder 310 flows into the premixing module 200 through the gas outlet nozzle 3223 and the air pipe.

[0074] As a specific embodiment of the present invention, Figure 6 and Figure 7 As shown, the premixing module 200 of this embodiment may include a premixing tank 210, which is used to receive the carbon dioxide gas from the gas supply module 300 and the water from the outside, mix them in the premixing tank 210 to form bubble water, and store the bubble water. An air inlet valve 221 may also be provided at the premixing tank 210, and the air outlet nozzle 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 of this embodiment includes a cover 220, and the cover 220 is sealed and connected to the tank body. An air inlet valve 221 is provided at the cover 220, and after the air inlet valve 221 is connected to the air outlet nozzle 3223 through an air pipe, the gas is input into the premixing tank 210. The air inlet valve 221 not only has the function of connecting the air pipe, but also has the function of controlling the air intake.

[0076] Specifically, the cover 220 of the premixing tank 210 is further provided with an exhaust valve 222 for exhausting the gas in the premixing tank 210. Specifically, since the premixing tank 210 is a sealed device, when water or other gas needs to be added thereto, for the convenience of adding, exhaust can be performed through the exhaust valve 222. In addition, since the premixing tank 210 contains bubble water, the concentration of the bubble water also requires constant alternation of intake and exhaust to obtain bubble water of a certain concentration.

[0077] Specifically, the bubble water device 100 of this embodiment may further include an exhaust pipe 230, which is connected to the 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 muffler 240 is provided at the exhaust pipe 230, and the muffler 240 is used to eliminate the sound of the exhaust pipe 230.

[0078] Since the gas pressure in the premixing tank 210 is relatively high, the gas sound is also relatively high when the exhaust valve 222 exhausts gas, so the sound is reduced by the muffler 240 on the exhaust pipe 230 to improve the user experience.

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

[0080] Since the premix tank 210 contains bubble water, when the exhaust valve 222 and the exhaust pipe 230 are exhausting, water vapor will inevitably exist in the gas. When the water vapor encounters the exhaust pipe 230, condensed water will appear and then discharged. Therefore, the water receiving tray 250 is required to catch the condensed water to prevent the condensed water from flowing freely and affecting the user experience.

[0081] Specifically, in this embodiment, at least one pressure relief valve 223 is further provided at the cover 220 of the premixing tank 210 to open when the pressure in the premixing tank 210 is greater than a preset value. The number of the pressure relief valves 223 in the specific premixing tank 210 may be one or more, and the pressure relief valve 223 is designed according to the pressure value that the premixing tank 210 can withstand, so as to avoid excessive pressure in the premixing tank 210 and ensure the safety of the premixing tank 210.

[0082] As a specific embodiment of the present invention, the bubble water device 100 of this embodiment may also include a water supply device (not shown in the figure), wherein a water inlet is provided at the premixing 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, a water pipe and a water pump. Purified water may be pre-stored in the water tank. Of course, a water pipe may be used to directly connect to an external water source. When directly connected to an external water source, a purification device may be provided at the water pipe so that the water can be directly drunk.

[0084] Specifically, in this embodiment, a water injection port 225 is provided on the cover body 220 . After the water supply device is connected to the water injection port 225 via a water pipe, external water is injected into the premixing tank 210 through the water injection port 225 .

[0085] Specifically, a water level detector 226 is further provided in the premixing tank of this embodiment, and the water level in the premixing tank 210 is detected by the water level detector 226, so that the premixing tank 210 is replenished with water in time when the water level in the premixing tank 210 is too low, or the replenishment of water is stopped when the water level in the premixing tank 210 is too high. As a specific embodiment of the present invention, the bubble water device 100 of this embodiment may also include a drainage device, which may include a drainage pipe and a driving device, and the bubble water in the premixing tank 210 is discharged for use by the driving device.

[0086] Specifically, a drain port 260 is provided at the cover 220 on the premix tank 210; the drain device is connected to the drain port 260 via a drain pipe, and when the bubble water device 100 receives a water extraction instruction, the drain device will directly extract bubble 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, which is connected to the water injection port 225 at the cover body 220 through an air pipe, so that the gas is input into the premixing tank 210 through the air pipe through the second air pump 330, so that the liquid in the premixing tank 210 is discharged from the drain pipe.

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

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

[0090] As another specific embodiment, the second air pump 330 of this embodiment is the same air pump as the first air pump 325. When the air pump is the same, the air pipe is formed into a main pipe 331 and two branch pipes 332, and a three-way valve (such as Fig. 9 As shown) or set a solenoid valve at each of the two branches (as shown Fig.10 shown).

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

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

[0093] Specifically, taking the case where the bubble water device 100 is placed in a refrigerator as an example, the principle of the entire bubble water device 100 is specifically described.

[0094] When gas needs to be delivered in the premix tank 210, the first air pump 325 is used to pump gas into the pumping device 320, and the gas enters the housing 322 from the air inlet nozzle 3221, pushing the piston 323 to move downward, and the piston 323 then pushes the push rod 321 to move downward, and 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 and enters the premix tank 210 through the gas outlet and the air pipe of the pumping device 320. 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 is opened, and the gas above the piston 323 is continuously discharged from the exhaust nozzle 3222, and the piston 323 continuously moves upward under the elastic force of the spring, and the push rod 321 moves upward, and the switch mechanism 311 of the gas cylinder 310 is closed, and the gas cylinder 310 stops supplying gas.

[0095] When the premixing tank 210 needs to be exhausted, the exhaust valve 222 can be opened to exhaust. When water is added to the premixing tank 210 or bubble water is formed, the exhaust valve 222 is required to exhaust.

[0096] When a water extraction instruction is received and bubble water is needed from the premixing tank 210, the second air pump can be used to inflate the premixing tank 210, or the water pump can be used to directly draw bubble water from the premixing tank 210, and the bubble water in the premixing tank 210 is discharged through the drainage device for user use.

[0097] 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.
