Description

Technical Field

[0001] This utility model relates to the field of sparkling water machine technology, and specifically to a sparkling water brewing structure. Background Technology

[0002] Sparkling water is a popular beverage among young people and an important ingredient in complex drinks such as juices and cocktails, making it a significant consumer product in various commercial settings. To enhance the taste, ice water is typically used in its preparation. Therefore, most sparkling water machines have a refrigeration unit that prepares ice water in a tank and then supplies it to a mixing chamber to mix with carbon dioxide gas to produce sparkling water. The refrigeration unit also needs to maintain the temperature of the sparkling water in the mixing chamber.

[0003] For example, Chinese patent CN217338247U discloses a sparkling water making component and a sparkling water machine. The sparkling water making component includes: an ice water tank for containing ice water; a mixing tank connected to the ice water tank via an ice water pipe to allow the ice water in the ice water tank to enter the mixing tank; and a refrigeration structure, a part of which is located inside the ice water tank to cool the ice water therein, and another part of which extends out of the ice water tank and onto the mixing tank to cool the sparkling water in the mixing tank. In this design, the refrigeration component cools both components (the water tank and the mixing tank) simultaneously. If the water temperature in the water tank (after replenishment) is too high, the water tank needs to be cooled first to prepare ice water, while the mixing tank remains in standby mode. Then, ice water is injected into the mixing tank, and carbon dioxide is introduced to dissolve in the ice water to form sparkling water. During the aeration process, the refrigeration component needs to maintain the water temperature in the mixing tank.

[0004] The aforementioned solutions and existing technologies all involve directly injecting carbon dioxide gas into ice water. The rapid decompression after injection creates large bubbles, affecting the solubility of carbon dioxide and resulting in a lower concentration of sparkling water. Furthermore, existing sparkling water machines extract ice water from the tank for preparation, leading to poor efficiency and consistency in both ice water and sparkling water production.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a sparkling water brewing structure with a reasonable structure, high carbon concentration, and high preparation efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention discloses a sparkling water brewing structure, comprising a cold water tank, a bubble tank, a gas source, a refrigeration component, a faucet, and a water supply component. The refrigeration component includes an evaporator coil. Both the bubble tank and the evaporator coil are disposed within the cold water tank, which contains a cold water coil. The water supply component is connected to the cold water tank and the cold water coil via pipelines. The cold water coil is connected to the bubble tank, and the cold water tank and the bubble tank are connected to the faucet via pipelines. The bubble tank is provided with an air inlet terminal, and an air stone is provided at the output end of the air inlet terminal. The gas source is connected to the input end of the air inlet terminal via a pipeline.

[0008] The water supply assembly provides purified water to the cold water tank and cold water coil. The evaporator coil cools the water in the cold water tank, lowering its temperature to near freezing. Water passing through the cold water coil exchanges heat with the water in the cold water tank, lowering its temperature to 2-5°C before being fed into the bubble tank. The gas source injects carbon dioxide gas into the bubble tank through pipelines. The bubble stone, made of ceramic, stainless steel, or other materials, has a microporous structure that breaks down the carbon dioxide gas into countless tiny bubbles, allowing the gas to dissolve evenly and rapidly in the ice water to prepare sparkling water.

[0009] Furthermore, both the evaporator coil and the bubble tank are located within the cold water tank. The continuous cooling from the evaporator coil controls the water temperature in the cold water tank to approach and maintain it at freezing point. Meanwhile, the sparkling water in the bubble tank continuously exchanges heat with the cold water in the tank, resulting in a more stable ambient temperature for sparkling water production. This allows the sparkling water machine to sustainably and efficiently produce both ice water and sparkling water. The cold water tank and bubble tank are connected to a faucet via pipes, providing a continuous supply of ice water and sparkling water, meeting the requirements for sparkling water machine applications in commercial environments.

[0010] According to the above scheme, the lower end of the cold water tank is provided with a bottom plate, and the bottom plate is provided with an assembly port; the lower end of the bubble tank is provided with a bottom plate, the bottom plate covers the assembly port and is fixedly connected to the bottom plate, so that the bubble tank is submerged in the cold water tank; the evaporator coil surrounds the bubble tank and is located close to the inner wall of the cold water tank; the cold water coil surrounds the bubble tank and is spaced between the bubble tank and the evaporator coil.

[0011] Specifically, an assembly port is provided on the bottom plate of the cold water tank. The bubble canister is inverted and inserted into the cold water tank through the assembly port. After the bottom plate of the canister is sealed, an appropriate amount of water is injected into the cold water tank so that the bubble canister is submerged in the cold water tank.

[0012] Preferably, the evaporator coil is spirally wound to form a cylindrical structure, surrounding the bubble tank and fixed inside the cold water tank. The evaporator coil can be close to the inner wall of the cold water tank. Of course, a gap is left between the evaporator coil and the inner wall of the cold water tank to make the heat exchange area between the evaporator coil and the cold water tank larger, thereby improving the cooling efficiency.

[0013] Similarly, the cold water coil is also spirally wound to form a cylindrical structure. The cold water coil is spaced between the bubble tank and the evaporator coil, so that the cold water coil can exchange heat with the ice water in the cold water tank, and then be fed into the bubble tank to prepare bubble water.

[0014] Understandably, on the horizontal projection surface, the inner cavity of the cold water tank, the evaporator coil, the cold water coil, and the bubble tank are arranged in a concentric and sequential manner, which can better utilize the volume of the cold water tank, increase the storage of ice water, and thus continuously provide ice water.

[0015] Furthermore, the evaporator coil is positioned close to the inner wall of the cold water tank. During the refrigeration process, the water temperature in the cold water tank exhibits a gradient change from the outside to the inside. In other words, if the water at the location of the evaporator coil has already frozen, the freezing state in the cold water tank gradually extends from the outside to the inside. The clean water flowing through the cold water coil exchanges heat with the water in the cold water tank before being introduced into the bubble tank. The bubble tank is located in the center of the cold water tank, and the temperature of the ice water in the bubble tank can be controlled between 2-5°C. Of course, the ice water in the cold water tank and the bubble water in the bubble tank are continuously used. The evaporator coil continuously or intermittently refrigerates, which can control the water temperature in the cold water tank and the water temperature in the bubble tank within the set range.

[0016] According to the above scheme, the cold water tank is also equipped with a stirring paddle, and a drive motor is installed on the upper plate of the cold water tank. The output shaft of the drive motor is connected to the stirring paddle, so that the stirring paddle is rotatably mounted in the cold water coil above the bubble tank. Preferably, the evaporator coil, cold water coil, and bubble tank are arranged concentrically and sequentially. When the water temperature in the cold water tank approaches the freezing point, the evaporator coil will freeze first, and the freezing state will gradually extend from the outside to the inside. The drive motor drives the stirring paddle to rotate in the cold water coil, and the stirring paddle drives the ice water in the cold water tank to flow, preventing the cold water coil and bubble tank from freezing.

[0017] The stirring paddle agitates the ice water in the cold water tank, which can form a thicker ice layer on the evaporator coil, maximizing the cooling capacity of the ice water in the cold water tank. Even if the ice water in the cold water tank is consumed, it can be quickly cooled down after replenishing with room temperature purified water, thus enhancing the continuity of ice water supply from the bubble water machine.

[0018] Of course, if the cold water tank has sufficient cooling capacity, the bubble tank can also be quickly replenished with ice water, thus enhancing the continuity of the bubble water machine's supply.

[0019] According to the above scheme, the bottom plate of the tank is provided with a first water inlet and a first water outlet. The water supply component includes a purified water source, which is connected to the first water inlet via a pipeline, and the first water outlet is connected to a faucet via a pipeline. The cold water tank is equipped with a first water level sensor and a temperature sensor, both of which are mounted on the upper plate of the cold water tank. The first water level sensor is used to control the water level in the cold water tank; generally, the water level in the cold water tank should submerge the aeration tank. The purified water source is directly connected to the first water inlet via a pipeline to continuously replenish the cold water tank with treated purified water. Of course, a solenoid valve is provided between the purified water source and the first water inlet. The temperature sensor is used to detect the water temperature in the cold water tank; generally, the water temperature in the cold water tank is controlled between 0-3℃.

[0020] It is understandable that when the water temperature in the cold water tank reaches 0℃, an ice layer will first form on the surface of the evaporator coil, and the freezing state in the cold water tank will gradually extend from the outside to the inside. Under the action of the agitator, a thicker ice layer can be formed on the surface of the evaporator coil, maximizing the cooling capacity of the ice water in the cold water tank.

[0021] According to the above scheme, the tank bottom plate is equipped with a second water inlet and a second water outlet. The water supply assembly also includes a booster pump and a pressure reducing valve. The purified water source, pressure reducing valve, cold water coil, booster pump, and second water inlet are connected sequentially via pipelines, and the second water outlet is connected to a faucet via a pipeline. A second water level sensor is installed inside the aerator tank and mounted on the tank bottom plate. The purified water source reduces the water pressure through the pressure reducing valve and then inputs the purified water into the cold water coil. The purified water exchanges heat with the ice water in the cold water tank within the cold water coil, and then the booster pump inputs the ice water in the cold water coil into the aerator tank through the second water inlet. Of course, a solenoid valve is installed on the pipeline between the purified water source and the pressure reducing valve.

[0022] According to the above scheme, a pressure relief valve is also provided on the bottom plate of the tank. An air inlet terminal is installed on the bottom plate of the tank, and a T-connector is provided between the input end of the air inlet terminal and the air source. A pressure sensor is connected to the T-connector. The pressure relief valve can release pressure in the bubble tank to ensure safety and prevent excessive pressure inside the bubble tank.

[0023] The pressure sensor is mounted on the tee connector and can detect the pressure inside the bubble tank as well as the pressure of the gas source.

[0024] According to the above scheme, a check valve (including a solenoid valve and a one-way valve) is further provided between the input end of the air inlet terminal and the three-way connector. The check valve can prevent the bubble water in the bubble tank from flowing back into the air source.

[0025] According to the above scheme, the refrigeration component also includes a compressor, a condenser, a capillary tube, and a dryer filter. The compressor, condenser, capillary tube, dryer filter, and evaporator coil are connected in sequence to form a heat exchange cycle. The compression refrigeration principle of the refrigeration component is existing technology, so it will not be described in detail here.

[0026] According to the above scheme, the evaporator coil and the bubble tank are both installed inside the cold water tank. The outer wall of the cold water tank is equipped with an insulation layer, which reduces the cost. The insulation layer can isolate the cold water tank from the outside heat conduction and reduce energy consumption.

[0027] This invention relates to a sparkling water brewing structure. The evaporator coil cools the water in the cold water tank to near freezing point. After heat exchange between the water in the cold water coil and the cold water tank, the water is fed into the bubble tank. The bubble stone decomposes carbon dioxide gas into tiny bubbles through its microporous structure, allowing it to dissolve quickly and evenly in the ice water, thus increasing the concentration of the sparkling water. The bubble tank is located inside the cold water tank, thereby continuously producing and outputting ice water and sparkling water. Attached Figure Description

[0030] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1As shown, the present invention discloses a sparkling water brewing structure, comprising a cold water tank 1, a bubble tank 2, an air source (not shown in the attached drawings), a refrigeration component, a faucet 11, and a water supply component. The refrigeration component includes an evaporator coil 3. Both the bubble tank 2 and the evaporator coil 3 are disposed within the cold water tank 1. The cold water tank 1 is provided with a cold water coil 21. The water supply component is connected to the cold water tank 1 and the cold water coil 21 respectively via pipelines. The cold water coil 21 is connected to the bubble tank 2. The cold water tank 1 and the bubble tank 2 are respectively connected to the faucet 11 via pipelines. The bubble tank 2 is provided with an air inlet terminal 22. The output end of the air inlet terminal 22 is provided with an air stone 23. The air source is connected to the input end of the air inlet terminal 22 via pipelines.

[0032] The water supply assembly provides purified water to the cold water tank 1 and the cold water coil 21 respectively. The evaporator coil 3 cools the water in the cold water tank 1, lowering the water temperature to near freezing point. Water passing through the cold water coil 21 exchanges heat with the water in the cold water tank 1, lowering the water temperature to 2-5°C before being fed into the bubble tank 2. The gas source injects carbon dioxide gas into the bubble tank 2 through pipelines. The bubble stone 23, made of ceramic, stainless steel, or other materials, has a microporous structure that decomposes the carbon dioxide gas into countless tiny bubbles, allowing the gas to dissolve evenly and rapidly in the ice water to prepare sparkling water.

[0033] Furthermore, both the evaporator coil 3 and the bubble tank 2 are located inside the cold water tank 1. The evaporator coil 3 continuously cools the water, controlling the water temperature in the cold water tank 1 to approach and maintain it at the freezing point. Meanwhile, the sparkling water in the bubble tank 2 continuously exchanges heat with the cold water in the cold water tank 1, making the ambient temperature for sparkling water production more stable. This allows the sparkling water machine to continuously and efficiently produce both ice water and sparkling water. The cold water tank 1 and the bubble tank 2 are connected to a water tap 11 via pipes, continuously providing ice water and sparkling water, meeting the application requirements of the sparkling water machine in commercial environments.

[0034] The lower end of the cold water tank 1 is provided with a tank bottom plate 12, and the tank bottom plate 12 is provided with an assembly port 120; the lower end of the bubble tank 2 is provided with a tank bottom plate 24, the tank bottom plate 24 covers the assembly port 120 and is fixedly connected to the tank bottom plate 12, so that the bubble tank 2 is submerged in the cold water tank 1; the evaporator coil 3 surrounds the bubble tank 2 and is provided close to the inner side wall of the cold water tank 1; the cold water coil 21 surrounds the bubble tank 2 and is provided at intervals between the bubble tank 2 and the evaporator coil 3.

[0035] Specifically, an assembly port 120 is provided on the bottom plate 12 at the lower end of the cold water tank 1. The bubble tank 2 is inverted and inserted into the cold water tank 1 through the assembly port 120. After the bottom plate 24 of the tank closes the assembly port 120, an appropriate amount of water is injected into the cold water tank 1 so that the bubble tank 2 is submerged in the cold water tank 1.

[0036] Preferably, the evaporator coil 3 is spirally wound to form a cylindrical structure, surrounding the bubble tank 2 and fixed inside the cold water tank 1. The evaporator coil 3 can be close to the inner wall of the cold water tank 1. Of course, a gap is left between the evaporator coil 3 and the inner wall of the cold water tank 1, so that the heat exchange area between the evaporator coil 3 and the cold water tank 1 is larger, thereby improving the cooling efficiency.

[0037] Similarly, the cold water coil 21 is also spirally coiled to form a cylindrical structure. The cold water coil 21 is spaced between the bubble tank 2 and the evaporator coil 3, so that the cold water coil 21 can exchange heat with the ice water in the cold water tank 1 and then be fed into the bubble tank 2 to prepare bubble water.

[0038] It is understandable that, on the horizontal projection plane, the inner cavity of the cold water tank 1, the evaporator coil 3, the cold water coil 21, and the bubble tank 2 are arranged in a concentric and sequential manner, which can better utilize the volume of the cold water tank 1, increase the storage of ice water, and thus continuously provide ice water.

[0039] Furthermore, the evaporator coil 3 is positioned close to the inner wall of the cold water tank 1. During the refrigeration process, the water temperature in the cold water tank 1 exhibits a gradient change from the outside to the inside. In other words, if the water at the location of the evaporator coil 3 has already frozen, the freezing state in the cold water tank 1 gradually extends from the outside to the inside. The clean water flowing through the cold water coil 21 exchanges heat with the water in the cold water tank 1 before being input into the bubble tank 2. The bubble tank 2 is located at the center of the cold water tank 1, and the temperature of the ice water in the bubble tank 2 can be controlled between 2-5℃. Of course, the ice water in the cold water tank 1 and the bubble water in the bubble tank 2 are continuously used. The evaporator coil 3 continuously or intermittently refrigerates, which can control the water temperature in the cold water tank 1 and the water temperature in the bubble tank 2 within the set range.

[0040] The cold water tank 1 is also equipped with a stirring paddle 13. A drive motor 14 is provided on the upper plate of the cold water tank 1. The output shaft of the drive motor 14 is connected to the stirring paddle 13, so that the stirring paddle 13 is rotatably mounted in the cold water coil 21 above the bubble tank 2. Preferably, the evaporator coil 3, the cold water coil 21, and the bubble tank 2 are arranged concentrically and sequentially. When the water temperature in the cold water tank 1 is close to the freezing point, the evaporator coil 3 will freeze first, and the freezing state will gradually extend from the outside to the inside. The drive motor 14 drives the stirring paddle 13 to rotate in the cold water coil 21, and the stirring paddle 13 drives the ice water in the cold water tank 1 to flow, preventing the cold water coil 21 and the bubble tank 2 from freezing.

[0041] The stirring paddle 13 can form a thicker ice layer at the evaporator coil 3 by stirring the ice water in the cold water tank 1, thereby maximizing the cooling capacity of the ice water in the cold water tank 1. Even if the ice water in the cold water tank 1 is consumed, it can be quickly cooled down after replenishing with room temperature purified water, thus enhancing the continuity of ice water supply from the bubble water machine.

[0042] Of course, if the cold water tank 1 has sufficient cooling capacity, the bubble tank 2 can also be quickly replenished with ice water, thus enhancing the continuity of the bubble water machine's supply of bubble water.

[0043] The bottom plate 12 of the tank is provided with a first water inlet 121 and a first water outlet 122. The water supply assembly includes a purified water source (not shown in the attached drawings), which is connected to the first water inlet 121 via a pipeline, and the first water outlet 122 is connected to a faucet 11 via a pipeline. The cold water tank 1 is provided with a first water level sensor 15 and a temperature sensor 16, both of which are mounted on the upper end plate of the cold water tank 1. The first water level sensor 15 is used to control the water level in the cold water tank 1, which should generally submerge the aerator 2. The purified water source is directly connected to the first water inlet 121 via a pipeline to continuously replenish the cold water tank 1 with treated purified water. Of course, a solenoid valve is provided between the purified water source and the first water inlet 121. The temperature sensor 16 is used to detect the water temperature in the cold water tank 1, which is generally controlled between 0-3℃.

[0044] It is understandable that when the water temperature in the cold water tank 1 reaches 0℃, an ice layer will first form on the surface of the evaporator coil 3, and the freezing state in the cold water tank 1 will gradually extend from the outside to the inside. Under the action of the stirring paddle 13, a thicker ice layer can be formed on the surface of the evaporator coil 3, so as to maximize the ice water storage capacity in the cold water tank 1.

[0045] The tank bottom plate 24 is provided with a second water inlet 241 and a second water outlet 242. The water supply assembly also includes a booster pump 25 and a pressure reducing valve 26. The purified water source, pressure reducing valve 26, cold water coil 21, booster pump 25, and second water inlet 241 are connected in sequence through pipelines. The second water outlet 242 is connected to a faucet 11 through a pipeline. The bubble tank 2 is provided with a second water level sensor 243, which is installed on the tank bottom plate 24. After the purified water source reduces the water pressure through the pressure reducing valve 26, the purified water is input into the cold water coil 21. The purified water exchanges heat with the ice water in the cold water tank 1 in the cold water coil 21, and then the booster pump 25 inputs the ice water in the cold water coil 21 into the bubble tank 2 through the second water inlet 241. Of course, a solenoid valve is provided on the pipeline between the purified water source and the pressure reducing valve 26.

[0046] The bottom plate 24 of the tank is also equipped with a pressure relief valve 244. The air inlet terminal 22 is installed on the bottom plate 24. A three-way connector 221 is provided between the input end of the air inlet terminal 22 and the air source. A pressure sensor 222 is connected to the three-way connector 221. The pressure relief valve 244 can relieve pressure on the bubble tank 2 to ensure safety and prevent excessive pressure inside the bubble tank 2.

[0047] The pressure sensor 222 is installed on the tee connector 221 and can detect the pressure inside the bubble tank 2 as well as the pressure of the gas source.

[0048] Furthermore, a check valve 223 (including a solenoid valve and a one-way valve) is provided between the input end of the air inlet terminal 22 and the three-way connector 221. The check valve 223 can prevent the bubble water in the bubble tank 2 from flowing back into the air source.

[0049] The refrigeration assembly also includes a compressor 31, a condenser 32, a capillary tube 33, and a dryer filter 34. The compressor 31, condenser 32, capillary tube 33, dryer filter 34, and evaporator coil 3 are connected in sequence to form a heat exchange cycle. The compression refrigeration principle of the refrigeration assembly is existing technology, so it will not be described in detail here.

[0050] The evaporator coil 3 and the bubble tank 2 are both installed inside the cold water tank 1. The outer wall of the cold water tank 1 is provided with a heat insulation layer 17, which reduces the cost. The heat insulation layer 17 can isolate the cold water tank 1 from the outside heat conduction and reduce energy consumption.

[0051] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
