Description

Technical Field

[0001] This application relates to the field of water purification technology, and in particular to a carbonization system and a water purifier. Background Technology

[0002] With people's increasing demands for higher quality and more diverse drinking water, water dispensers, as an indispensable part of daily life, have gradually evolved into more functional drinking water purification devices. However, most existing water dispensers can only provide hot or cold water to meet basic drinking needs, but they have significant limitations in meeting more diverse needs, especially for consumers who need carbonated water, where the selection is particularly limited. Carbonated water refers to water that has carbon dioxide gas added to it to form carbonated bubbles.

[0003] Traditional carbonized water technology typically uses a "hand-operated" bubble water machine. Its basic working principle involves manually pouring water filtered by a water purifier into a special bottle, then placing the bottle into the carbonization machine, where an air pump fills the water with carbon dioxide gas to form bubbles.

[0004] However, while traditional carbonated water machines can produce carbonated water, their operation is cumbersome and limited. Specifically, users need to filter the water through a water purifier before filling it into a carbonated bottle, and then put the bottle into the carbonated machine. This process increases the complexity of obtaining carbonated water and reduces its convenience and efficiency. Utility Model Content

[0005] Therefore, it is necessary to provide a carbonization system and water purifier that can reduce the complexity of obtaining carbonized water and improve the convenience and efficiency of obtaining carbonized water, in order to address the above-mentioned technical problems.

[0006] This application provides a carbonization system, comprising:

[0007] The refrigeration module includes a heat exchanger and a cold water tank. The refrigeration module is used to cool the room temperature water in the cold water tank to cold water through the heat exchanger.

[0008] The booster pump is located outside the cold water tank; the inlet of the booster pump is connected to the outlet of the cold water tank.

[0009] The carbonization tank is located inside the cold water tank, with the end of the carbonization tank furthest from the top cover located in the inner ring of the heat exchanger. The air inlet of the carbonization tank is connected to the air outlet of the carbon dioxide cylinder, and the first water inlet of the carbonization tank is connected to the water outlet of the booster pump. The booster pump is used to receive cold water from the cold water tank and mix the cold water in the cold water tank with carbon dioxide gas to generate steam.

[0010] In one embodiment, the carbonization tank is provided with a bracket, and the bracket has mounting holes for fixing the carbonization tank in place.

[0011] In one embodiment, the top cover of the cold water tank has a receiving hole and a mounting post corresponding to the mounting hole; the tank body of the carbonization tank passes through the receiving hole and is connected to the top cover of the cold water tank through the mounting hole and the mounting post.

[0012] In one embodiment, the radial distance of the receiving hole is greater than the radial distance of the carbonization tank body, and the radial distance of the receiving hole is less than the radial distance of the support, wherein the top of the carbonization tank body protrudes from the top cover of the cold water tank.

[0013] In one embodiment, the carbonization system further includes:

[0014] The solenoid valve is connected to the outlet of the carbonization tank and is used to control the flow rate of steam and water inside the carbonization tank.

[0015] In one embodiment, the carbonization system further includes insulation components surrounding the outer peripheral wall, bottom wall, and top cover of the cold water tank.

[0016] In one embodiment, the top of the carbonization tank is provided with at least one level probe, which is used to detect the liquid level of the carbonated water inside the carbonization tank.

[0017] In one embodiment, the refrigeration module further includes a compressor, a capillary tube, a dryer filter, and a condenser; the compressor is located outside the cold water tank and is connected to a heat exchanger; a first end of the capillary tube is connected to the heat exchanger, a second end of the capillary tube is connected to a first end of the dryer filter, a second end of the dryer filter is connected to a first end of the condenser, and a second end of the condenser is connected to the compressor.

[0018] Secondly, this application provides a water purifier, including a housing, a filter device, and any one of the carbonization systems provided in the first aspect, wherein the filter device and the carbonization system are disposed inside the housing.

[0019] In one embodiment, the water purifier further includes a filtration device, which includes a filter cartridge assembly; the outlet of the filtration device is connected to a second inlet of the cold water tank or to the outlet of the water purifier.

[0020] The aforementioned carbonization system and water purifier include: a refrigeration module comprising a heat exchanger and a cold water tank; a booster pump located outside the cold water tank; the inlet of the booster pump connected to the outlet of the cold water tank; and a carbonization tank located inside the cold water tank, with the end of the carbonization tank furthest from the top cover located within the inner ring of the heat exchanger. The carbonization tank receives cold water from the cold water tank via the booster pump and mixes the cold water with carbon dioxide gas to generate carbonated water. In this carbonization system, the carbonization tank's location inside the cold water tank, with its end furthest from the top cover located within the inner ring of the heat exchanger, allows the carbonization tank to remain at a low temperature, thereby increasing the solubility of carbon dioxide inside the tank and improving the carbonization efficiency. The location of the carbonization tank inside the cold water tank also facilitates the preservation of the carbonated water, preventing rapid release of carbon dioxide gas due to changes in external temperature, thus ensuring that the carbonated water concentration remains at a relatively high level. Furthermore, this carbonization system uses a heat exchanger, a booster pump, and a carbon dioxide cylinder to ensure that the cold water in the carbonization tank is fully mixed with the carbon dioxide gas, thereby generating carbonated water. This reduces the complexity of obtaining carbonated water and improves the convenience and efficiency of obtaining it. Attached Figure Description

[0032] See Figures 1 to 3 , Figure 1 A schematic diagram of the carbonization system in one embodiment of the present invention is shown. Figure 2 for Figure 1 The carbonization system does not show a structural diagram of the insulation layer carbonization system. Figure 3 for Figure 1 The carbonization system does not show a structural diagram of the top cover 21. One embodiment of this utility model provides a carbonization system including a refrigeration module, a heat exchanger 10, and a cold water tank 20. The heat exchanger 10 is located at the bottom of the cold water tank 20, and the top cover 21 of the cold water tank 20 has a receiving hole. The refrigeration module is used to cool the room temperature water in the cold water tank 20 to cold water through the heat exchanger 10. A booster pump 30 is located outside the cold water tank 20. The inlet of the booster pump 30 is connected to the outlet of the cold water tank 20. The water outlet of the booster pump 30 is connected to the first water inlet 44 of the carbonization tank; the carbonization tank 40 is coaxially arranged with the heat exchanger 10 and is located inside the cold water tank 20; and the end of the carbonization tank 40 away from the top cover 21 is located in the inner ring of the heat exchanger 10; the air inlet 45 of the carbonization tank is connected to the air outlet of the carbon dioxide cylinder 50, and the carbonization tank 40 receives cold water from the cold water tank 20 through the booster pump 30, which is used to mix the cold water in the cold water tank 20 with carbon dioxide gas to generate steam water.

[0033] The refrigeration module includes a heat exchanger 10 and a cold water tank 20. The cold water tank 20 is a water storage container. The heat exchanger 10 is located inside the cold water tank 20 and at its bottom. The heat exchanger 10 is used to rapidly cool the water in the cold water tank 20 through heat exchange, providing a low-temperature water source for the carbonization tank 40. The heat exchanger 10 ensures that the water temperature in the cold water tank 20 remains low, so that carbon dioxide can dissolve in the water in the carbonization tank 40 at a low temperature. The top cover 21 of the cold water tank 20 is located on top of the cold water tank 20, and a receiving hole is provided on the top cover 21. This receiving hole allows the cold water tank 20 to accommodate the carbonization tank 40 and place the carbonization tank 40 inside the cold water tank 20. The second inlet 23 of the cold water tank is used to introduce filtered water. The outlet of the cold water tank 20 is connected to the inlet of the booster pump 30. Optionally, the outlet of the cold water tank 20 can be located at the bottom of the cold water tank 20. The heat exchanger 10 can be configured as an evaporator.

[0034] The booster pump 30 is located outside the cold water tank 20. The specific location of the booster pump 30 is not limited, as long as it can effectively draw cold water from the cold water tank 20. For example, the booster pump 30 can be fixed to the side or bottom of the cold water tank 20, or it can be fixed to the bracket 41 of the carbonation tank 40. The inlet of the booster pump 30 is connected to the outlet of the cold water tank 20, and the outlet of the booster pump 30 is connected to the first inlet 44 of the carbonation tank. It is used to draw cold water from the cold water tank 20 and pressurize and deliver the cold water to the carbonation tank 40. The booster pump 30 ensures that the cold water in the cold water tank 20 enters the carbonation tank 40 at a constant water pressure, which can prevent fluctuations in water flow from affecting the dissolution effect of carbon dioxide in the carbonation tank 40, thereby ensuring the quality of the carbonated beverage. In addition, using the booster pump 30 for pressurization makes the concentration of the produced carbonated beverage more stable, and when there is sufficient cold water in the cold water tank 20, carbonated beverage can be continuously produced for drinking.

[0035] The carbonization tank 40 is an important component of this system. Its inlet 45 is connected to the outlet of the carbon dioxide cylinder 50, which supplies the carbon dioxide gas required for carbonization to the tank 40. This allows the carbon dioxide gas to enter the tank 40 and mix thoroughly with the cold water inside under low temperature and high pressure, generating bubbles and ultimately producing carbonated water. The carbonization tank 40 is located inside the cold water tank 20, coaxially aligned with the heat exchanger 10, with the end of the tank 40 furthest from the top cover 21 of the cold water tank 20 located within the inner ring of the heat exchanger 10 (the tank 40 and the heat exchanger 10 are in an inside-outside position). The portion of the tank 40 inside the cold water tank 20 is in full contact with the cold water, ensuring the tank 40 remains at a low temperature. This increases the solubility of carbon dioxide inside the tank 40, prevents carbon dioxide escape, and improves the carbonization efficiency and safety within the tank 40.

[0036] In this embodiment, the water source in the cold water tank 20 is cooled to cold water by the heat exchanger 10; the first water inlet 44 of the carbonization tank is connected to the water outlet of the booster pump 30, and the booster pump 30 pumps the cold water in the cold water tank 20 into the carbonization tank 40; the air inlet 45 of the carbonization tank is connected to the air outlet of the carbon dioxide cylinder 50 to receive the carbon dioxide gas in the carbon dioxide cylinder 50, so that the cold water in the carbonization tank 40 can be fully mixed with the carbon dioxide gas to generate soda water, which can reduce the complexity of obtaining carbonized water and improve the convenience and efficiency of obtaining carbonized water. The carbonation tank 40 is located inside the cold water tank 20 and is coaxially arranged with the heat exchanger 10. The end of the carbonation tank 40 away from the top cover 21 of the cold water tank 20 is located on the inner ring of the heat exchanger 10, which allows the carbonation tank 40 to always be in a low-temperature state, thereby increasing the solubility of carbon dioxide inside the carbonation tank 40 and improving the carbonation efficiency inside the carbonation tank 40. At the same time, the carbonation tank 40 is located inside the cold water tank 20, which is more conducive to the preservation of the carbonated beverage, so that the carbonation tank 40 will not release carbon dioxide gas rapidly due to changes in the external temperature, thereby ensuring that the carbonated beverage concentration can always be maintained at a high concentration. Furthermore, placing the carbonation tank 40 inside the cold water tank 20 allows the design layout of the carbonation system and even the water purifier to be more compact and miniaturized, thereby saving installation space.

[0037] In the previous exemplary embodiment, the carbon dioxide cylinder 50 is located outside the cold water tank 20. The carbon dioxide cylinder 50 can be fixed to the side or bottom of the cold water tank 20, or it can be fixed to the bracket 41 of the carbonization tank 40. The outlet of the carbon dioxide cylinder 50 is connected to the inlet 45 of the carbonization tank. Carbon dioxide is sent into the carbonization tank 40 through the inlet 45, allowing the carbon dioxide to mix with cold water inside the carbonization tank 40. Due to the low temperature and high pressure environment inside the carbonization tank 40, the carbon dioxide can quickly dissolve in the cold water, thereby generating carbonated water. Optionally, the outlet of the carbon dioxide cylinder 50 is connected to the inlet 45 of the carbonization tank through a pipe, and a pressure reducing device is installed on the pipe. The pressure reducing device controls the gas pressure to ensure that the carbon dioxide gas enters the carbonization tank 40 under appropriate pressure. Furthermore, a pressure relief valve is also provided on the pipe. This pressure relief valve can automatically release pressure when the pressure inside the carbonization tank 40 exceeds a set value, avoiding safety problems caused by excessive pressure.

[0038] In one exemplary embodiment, please refer to Figure 2 The carbonization tank 40 is provided with a bracket 41, and the bracket 41 is provided with a mounting hole 42, which is used to fix the carbonization tank 40.

[0039] Optionally, the upper cover 21 of the cold water tank 20 has a receiving hole and a mounting post 22 corresponding to the mounting hole 42. The radial distance of the receiving hole is greater than the radial distance of the tank body of the carbonization tank 40, and the radial distance of the receiving hole is less than the radial distance of the bracket 41. The tank body of the carbonization tank 40 passes through the receiving hole and is connected to the mounting post 22 of the upper cover 21 of the cold water tank 20 through the mounting hole 42 on the bracket 41, so that the top of the tank body of the carbonization tank 40 protrudes from the upper cover 21 of the cold water tank 20.

[0040] The radial distance of the bracket 41 is the radial distance of its outer diameter. The bracket 41 is provided on the body of the carbonization tank 40, located at the top of the carbonization tank 40. The bracket 41 is approximately annular in shape. The inner diameter of this annular bracket 41 matches the outer structure of the top of the carbonization tank 40, while the outer diameter of the bracket 41 is larger than the diameter of the receiving hole on the upper cover 21 of the cold water tank 20. Therefore, the outer edge of the bracket 41 protrudes from the top of the cold water tank 20, meaning that the bracket 41 can match the upper cover 21, effectively supporting the carbonization tank 40 and providing sufficient support force. Optionally, the outer edge of the bracket 41 is provided with several support protrusions, which have supporting and fixing functions. Each support protrusion has a mounting hole 42, and each mounting hole 42 corresponds one-to-one with the mounting post 22 of the upper cover 21 of the cold water tank 20. The carbonization tank 40 is fixedly connected to the upper cover 21 of the cold water tank 20 through the corresponding mounting holes 42 and mounting posts 22, ensuring that the carbonization tank 40 can be firmly fixed inside the cold water tank 20. Since the radial distance of the outer diameter of the bracket 41 is greater than the radial distance of the receiving hole, while the radial distance of the tank body of the carbonization tank 40 is less than the radial distance of the receiving hole, the top of the tank body of the carbonization tank 40 (i.e., the part above the bracket 41) can protrude from the upper cover 21 of the cold water tank 20, while ensuring that the other parts of the carbonization tank 40 (i.e., the part below the top) can fully contact the cold water inside the cold water tank 20. The above design allows the top of the tank body of the carbonization tank 40 to be easily connected to water pipes and gas pipes, while keeping the carbonization tank 40 in a low-temperature state for a long time.

[0041] In this embodiment, the top of the carbonization tank 40 is provided with a bracket 41 and a mounting hole 42, and the upper cover 21 of the cold water tank 20 is provided with a receiving hole and a mounting post 22. The tank body of the carbonization tank 40 can pass through the receiving hole through the upper cover 21 and is assembled with the upper cover 21 through the bracket 41, the mounting hole 42, and the mounting post 22. This allows the top of the carbonization tank 40 to protrude from the upper cover 21, and ensures that the rest of the tank body of the carbonization tank 40 is located inside the cold water tank 20 and in contact with cold water. This allows the carbonization tank 40 to be easily connected to external pipes (such as water pipes and...). The gas pipeline facilitates easier connection and disassembly of the carbonization tank 40 during operation and maintenance. It also ensures the carbonization tank 40 remains at a low temperature, thus optimizing the carbonization effect. Furthermore, the top of the carbonization tank 40 is designed to protrude from the top cover 21 of the cold water tank 20, while the rest remains inside the cold water tank 20. This optimizes the space utilization of the cold water tank 20, allowing the cold water inside the tank to contact more carbonization tanks 40, improving cooling efficiency. The protruding top also facilitates pipeline connection, saving installation space.

[0042] In an exemplary embodiment, the refrigeration module further includes a compressor 80, a capillary tube, a dryer filter, and a condenser; the compressor 80 is located outside the cold water tank 20 and connected to the heat exchanger 10; a first end of the capillary tube is connected to the heat exchanger 10, a second end of the capillary tube is connected to a first end of the dryer filter, a second end of the dryer filter is connected to a first end of the condenser, and a second end of the condenser is connected to the compressor 80.

[0043] The refrigeration module comprises a compressor 80, a heat exchanger 10, a capillary tube, a dryer filter, a condenser, and a cold water tank 20. Exemplarily, the heat exchanger 10 is located inside the cold water tank 20 and at its bottom. The heat exchanger 10 is connected to the cold water tank 20 and, as the cooling end of the refrigeration module, absorbs ambient heat, allowing the refrigerant to exchange heat with the water in the cold water tank 20, thereby achieving a cooling effect and maintaining the water in the cold water tank 20 at a low temperature. The compressor 80, capillary tube, dryer filter, and condenser are all located outside the cold water tank 20. The compressor 80 is connected to the heat exchanger 10, the heat exchanger 10 is connected to the first end of the capillary tube, the second end of the capillary tube is connected to the first end of the dryer filter, the second end of the dryer filter is connected to the first end of the condenser, and the second end of the condenser is connected to the compressor 80. Optionally, the refrigeration module achieves a refrigeration cycle through a series of interconnected components, thereby providing a continuous low-temperature environment for the cold water tank 20.

[0044] In this embodiment, the refrigeration module can efficiently provide continuous cooling to the cold water tank 20, ensuring that the water temperature inside the cold water tank 20 is maintained at a low temperature; and the compressor 80 is located outside the cold water tank 20, which optimizes the internal space of the cold water tank 20 and improves the compactness and reliability of the entire system.

[0045] In one exemplary embodiment, the top of the carbonization tank 40 is provided with at least one liquid level probe 70, which is used to detect the liquid level height of the soda water inside the carbonization tank 40.

[0046] In order to effectively monitor the state of the liquid inside the carbonization tank 40, at least one liquid level probe 70 can be installed on the top of the carbonization tank 40. The liquid level probe 70 is used to detect the liquid level height inside the carbonization tank 40 in real time.

[0047] In this embodiment, at least one liquid level probe 70 is provided on the top of the carbonization tank 40, which can obtain the liquid level height in the carbonization tank 40 in real time, determine the change of liquid level, prevent failures or safety accidents caused by abnormal liquid level in the carbonization tank 40, and enhance the safety of the operation process.

[0048] In one exemplary embodiment, the interior of the cold water tank 20 is equipped with a float and a negative temperature coefficient (NTC) probe, which are used to detect the water level and temperature of the liquid inside the cold water tank 20, respectively.

[0049] The float is used to detect changes in the water level in the cold water tank 20, while the NTC probe is used to monitor the temperature of the liquid in the cold water tank 20 in real time. The float and NTC probe work together to enhance the stability and reliability of the carbonization system, effectively preventing equipment damage or malfunction due to abnormal liquid level or temperature, and improving the overall efficiency and service life of the carbonization system.

[0050] In an exemplary embodiment, the carbonization system further includes an insulation element 90 surrounding the outer peripheral wall, bottom wall, and upper cover 21 of the cold water tank 20.

[0051] Optionally, the carbonization system also includes an insulation component 90, which surrounds the outer peripheral wall and bottom wall of the cold water tank 20. This insulation component 90 ensures that the liquid temperature inside the cold water tank 20 remains stable, allowing the cold water tank 20 to more effectively maintain a low temperature, thereby improving the stability and efficiency of the carbonization process. Optionally, the outer peripheral wall, bottom wall, and top cover 21 of the cold water tank 20 are all covered with the insulation component 90.

[0052] In one exemplary embodiment, the carbonization system further includes a solenoid valve 60 connected to the outlet 43 of the carbonization tank, used to control the flow rate of the carbonated water within the carbonization tank 40. Optionally, the carbonization system also includes a control module, the opening and closing of which can be precisely adjusted. The solenoid valve 60 can be opened when needed to ensure the stability of the carbonated water output. When the carbonated water is generated and ready for output, the solenoid valve 60 allows the carbonated water to flow out of the carbonization tank 40 and controls the flow rate of the carbonated water within the carbonization tank 40.

[0053] In this embodiment, the solenoid valve 60 is connected to the outlet 43 of the carbonization tank. The solenoid valve 60 controls the water flow to ensure a stable output of steam and water in the carbonization tank 40.

[0054] Secondly, this application provides a water purifier, which includes a housing, a filter device, and any one of the carbonization systems provided in the first aspect, wherein the filter device and the carbonization system are disposed inside the housing.

[0055] The water purifier includes any of the carbonization systems provided in the first aspect. This carbonization system is the core component of the water purifier and is responsible for producing carbonated water. Specifically, the water purifier may also have ice-making and heating functions to meet the diverse needs of users for various drinking water types. In this embodiment, the water purifier can be a tabletop or built-in model, making it more convenient and applicable, and enabling its widespread use in homes, offices, or commercial environments.

[0056] In the previous exemplary embodiment, the filtration device includes a filter cartridge assembly; the outlet of the filtration device is connected to the second inlet 23 of the cold water tank or to the outlet of the water purifier.

[0057] Optionally, the filter element assembly includes at least one filter media, which can be a composite filter media, PP cotton filter media, activated carbon filter media, or RO reverse osmosis membrane filter media; the composite filter media can include PP cotton filter media and activated carbon filter media, or it can include pre-filter media and post-filter media.

[0058] In addition to the carbonization system described in the first aspect, the water purifier also includes a housing and a filtration device. The filtration device may include one or at least two sets of filter cartridges, with the at least two sets of filter cartridges connected by a water channel plate. Each set of filter cartridges includes at least one filter media. The at least two sets of filter cartridges may include two or more sets of filter cartridges, with each set including at least one filter media.

[0059] Optionally, when the filtration device includes a set of filter cartridges, the set of filter cartridges may include at least one filter medium (PP cotton filter medium, activated carbon filter, RO reverse osmosis membrane filter medium, etc.). When the filtration device includes two sets of filter cartridges, optionally, one set of filter cartridges may include only one type of filter medium (such as RO reverse osmosis membrane filter medium), while the other set of filter cartridges may include multiple types of filter media other than RO reverse osmosis membrane filter media (such as PP cotton filter medium, activated carbon filter medium, etc.). When the filtration device includes multiple sets of filter cartridges (more than two sets of filter cartridges), each set of filter cartridges may include only one type of filter medium. The filtration device may also adopt other combinations, which are not specifically limited here; and the filter media used in each set of filter cartridges and the combination of filter media in each set of filter cartridges are not specifically limited here.

[0060] The outlet of the filter device can be connected to the second inlet 23 of the cold water tank of the refrigeration module to replenish the cold water tank 20. The outlet of the filter device can also be connected to the outlet of the water purifier to dispense room temperature water for users. The outlet of the cold water tank 20 can also be connected to the outlet of the water purifier to dispense cold water for users.

[0061] Optionally, the outlet 43 of the carbonization tank is connected to the inlet of the solenoid valve 60, and the outlet of the solenoid valve 60 is connected to the outlet of the water purifier. When the carbonization system is working, the carbonization tank 40 continuously produces soft drinks.
