Description

Technical Field

[0001] This application relates to the field of drinking water devices, and more particularly to a refrigerated soda water tank. Background Technology

[0002] As people's living standards continue to improve, they are paying more and more attention to the quality and taste of beverages. In today's fast-paced life, beverages are no longer just about quenching thirst, but have become part of people's pursuit of quality of life and enjoyment. Iced soda water, with its refreshing and unique effervescence, can instantly dispel the summer heat and bring a pleasant drinking experience, thus it is highly favored by consumers in the market.

[0003] Existing refrigerant soda water tanks mainly consist of a tank body, a refrigeration unit installed within the tank body, an inlet pipe installed within the tank body, a water inlet pipe for supplying water, and a water outlet pipe for discharging soda water. A one-way valve is typically installed at the water inlet pipe. During the use of the refrigerant soda water tank, this single one-way valve often malfunctions, causing a pressure drop within the tank body and resulting in soda water flowing out from the water inlet pipe.

[0004] In response to the aforementioned technologies, the inventor provides a refrigerated soda water container. Utility Model Content

[0005] To reduce the probability of backflow of soda water, this application provides a refrigerated soda water container.

[0006] The technical solution for a refrigerated soda water tank provided in this application is as follows:

[0007] A refrigerated soda water tank includes a mounting tank body having a receiving cavity for containing soda water. The mounting tank body is equipped with a refrigeration component, an air inlet pipe communicating with the receiving cavity, a water supply component for supplying soda water, and a water level probe component. The water supply component includes an inlet pipe communicating with the receiving cavity for supplying water and an outlet pipe for discharging soda water. A one-way valve assembly is provided at the inlet pipe, and the inlet pipe has a limiting plate that seals with the bottom surface of the one-way valve assembly, and the limiting plate has a spray nozzle communicating with the receiving cavity.

[0008] By adopting the above technical solution, during the operation of the refrigerated soda water tank, water is introduced through the inlet pipe. Due to the spray nozzle at the limiting plate of the inlet pipe, the water is introduced in a mist form when it enters the receiving cavity of the tank. Simultaneously, carbon dioxide is introduced into the receiving cavity through the air inlet pipe, allowing the carbon dioxide and mist water to mix thoroughly. The refrigeration component improves the solubility of carbon dioxide and cools the soda water. The water level probe component helps to detect the water level in the receiving cavity, ensuring that there is always a certain level of soda water in the receiving cavity. Finally, the cooled soda water is output from the outlet pipe. A one-way valve assembly is installed at the inlet pipe. The cooperation of multiple one-way valves provides multiple guarantees for ensuring stable gas pressure inside the tank, helping to reduce the probability of soda water flowing out of the inlet pipe.

[0009] Optionally, the one-way valve assembly includes two one-way valves arranged vertically on the inlet pipe, and the two one-way valves are sealed together.

[0010] By adopting the above technical solution, two one-way valves are arranged vertically to the water inlet pipe and are sealed together. When one of the one-way valves fails, the other one-way valve can still work normally, which helps to provide double protection against the backflow of soda water and ensures the carbonation effect of soda water.

[0011] Optionally, the refrigeration assembly includes a cold water pipe installed in the accommodating cavity and an evaporator pipe for refrigeration. The cold water pipe is arranged in an overlapping manner around the central axis of the mounting tank, and the evaporator pipe is arranged in the gap formed by the cold water pipe.

[0012] By adopting the above technical solution, the specific structure of the refrigeration component is disclosed. The cold water pipes are arranged in an overlapping manner around the central axis of the mounting tank, forming a dense three-dimensional heat exchange network. This helps to increase the contact area between the soda water and the cold water pipes, thus accelerating the cooling effect on the soda water. The evaporator is arranged in the gaps formed by the surrounding cold water pipes, allowing the low-temperature effect of the evaporator to quickly reach the soda water and increase the solubility of carbon dioxide in the water.

[0013] Optionally, the evaporator tubes are arranged around the central axis of the mounting tank, and there is a refrigeration gap between adjacent evaporator tubes.

[0014] By adopting the above technical solution, the arrangement of the evaporator tubes around the central axis of the installation tank and the refrigeration gap between adjacent evaporator tubes help to increase the contact area between the evaporator tubes and the soda water, thereby improving the refrigeration effect on the soda water.

[0015] Optionally, the refrigeration assembly further includes a fixing bracket for fixing the evaporator tube, wherein the fixing bracket is provided with fixing grooves spaced apart along the length of the fixing bracket for arranging the evaporator tube.

[0016] By adopting the above technical solution, the setting of the fixed bracket and the setting of the fixed groove in the fixed bracket helps to fix the evaporator tube arranged in the accommodating cavity, while ensuring that there is a cooling gap between adjacent evaporator tubes. The fixed bracket can also act as a shock absorber to reduce the vibration amplitude of the evaporator tube during the operation of the cooling soda water tank.

[0017] Optionally, the fixing bracket includes a support plate and a limiting tube installed on the support plate and cooperating with the support plate to fix the evaporator tube. The support plate has an L-shaped cross-section and a bent portion, and the limiting tube is arranged at the bent portion.

[0018] By adopting the above technical solution, through the cooperation between the support plate and the limiting tube, when the evaporator is fixed in the fixed bracket, it helps to set the limiting tube of the bending part of the support plate, so that the evaporator is restricted in the fixed groove, reducing the probability of the evaporator coming out of the fixed groove.

[0019] Optionally, the accommodating cavity is provided with two fixing brackets for fixing the evaporation tube.

[0020] By adopting the above technical solution, the installation of two fixed supports helps to further improve the stability of the evaporator tube.

[0021] Optionally, the cold water pipe includes a cold water inlet and a cold water outlet arranged at the top of the mounting tank, and the evaporation pipe includes an inlet installed at the bottom of the mounting tank and an outlet installed at the bottom of the mounting tank.

[0022] By adopting the above technical solution, the cold water inlet and outlet of the cold water pipe are arranged at the top of the installation tank. When low-temperature cold water is input from the top, it will naturally sink, forming a gravity-driven flow from top to bottom. The water, after being heated by the soda water, will decrease in density due to thermal expansion and contraction and be discharged from the top. The steam pipe inlet and outlet are located at the bottom of the installation tank, cooling the bottom area of ​​the tank, which is most prone to heat accumulation, from the source, thus improving the cooling effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A refrigerated soda water tank, wherein a one-way valve assembly is provided at the water inlet pipe, and through the cooperation of multiple one-way valves, multiple guarantees are provided to ensure the stability of the gas pressure inside the tank, which helps to reduce the probability of soda water flowing out from the water inlet pipe. Furthermore, the setting of the spray nozzle at the limiting plate of the water inlet pipe allows water to be input into the accommodating cavity in the form of mist, thereby improving the mixing effect of water and carbon dioxide.

[0025] 2. The fixed bracket and the fixed groove in the fixed bracket help to fix the evaporator tube arranged in the accommodating cavity, while ensuring that there is a cooling gap between adjacent evaporator tubes. The fixed bracket can also act as a shock absorber to reduce the vibration amplitude of the evaporator tube during the operation of the cooling soda water tank.

[0026] 3. The arrangement of the refrigeration components and the coordination between the cold water pipe and the steam pipe help to improve the solubility of carbon dioxide in water and the cooling effect on soda water. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a refrigerant soda water container. (See also...) Figure 1 and Figure 2A chilled soda water tank includes a mounting tank 1 with a receiving cavity 11 for holding soda water. The mounting tank 1 also includes a chilling assembly 2, an air inlet pipe 3 connected to the receiving cavity 11, a water supply assembly 4 communicating with the receiving cavity 11 and for supplying soda water, and a water level probe assembly 5 for detecting the water level in the receiving cavity 11. The water level probe assembly 5 ensures that the receiving cavity 11 always contains a certain level of soda water.

[0035] Reference Figure 2 and Figure 3 The water supply assembly 4 includes an inlet pipe 41 connected to the accommodating cavity 11 for water input and an outlet pipe 42 for discharging soda water. The central axis of the outlet pipe 42 overlaps with the central axis of the mounting tank 1, and the bottom of the outlet pipe 42 extends to the top of the bottom surface of the accommodating cavity 11 of the mounting tank 1. To ensure the stability of the pressure inside the mounting tank 1 and reduce the probability of soda water being discharged from the inlet pipe 41, a one-way valve assembly is installed at the inlet pipe 41. The one-way valve assembly includes two one-way valves 43 arranged vertically within the inlet pipe 41, and the two one-way valves 43 are sealed together. This ensures that if one one-way valve 43 fails during the operation of the chilled soda water tank, the other one-way valve 43 can still operate normally, providing double protection for the stable operation of the chilled soda water tank. The water inlet pipe 41 has a limiting plate 411 that seals with the bottom surface of the one-way valve assembly. The limiting plate 411 has a spray nozzle 412 that communicates with the accommodating cavity 11. The diameter of the spray nozzle 412 is much smaller than the diameter of the water inlet pipe 41, so that water can be input into the accommodating cavity 11 in the form of a mist, thereby improving the mixing effect with carbon dioxide.

[0036] Reference Figure 2 The refrigeration assembly 2 includes a cold water pipe 21 installed within the accommodating cavity 11 and an evaporator pipe 22 for refrigeration. The cold water pipe 21 is arranged vertically, overlapping each other, around the central axis of the mounting tank 1 and close to the side wall of the accommodating cavity 11. The evaporator pipe 22 is arranged within the gap formed by the cold water pipe 21, and also around the central axis of the mounting tank 1. Adjacent evaporator pipes 22 have a refrigeration gap 221, which helps to increase the contact area between the evaporator pipe 22 and the soda water, thereby improving the refrigeration effect on the soda water. The cold water pipe 21 includes a cold water inlet 211 arranged at the top of the mounting tank 1 and a cold water outlet 212 arranged on the top surface of the mounting tank 1, so that the cold energy is released from top to bottom. The evaporation pipe 22 includes an inlet 222 installed at the bottom of the mounting tank 1 and an outlet 223 installed at the bottom of the mounting tank 1, so that the cold energy is transferred from bottom to top. Through the cooperation between the two, it helps to improve the solubility of carbon dioxide in water and at the same time improve the cooling effect of soda water.

[0037] Reference Figure 2 , Figure 4 and Figure 5 To reduce the vibration amplitude of the evaporator tube 22 during the operation of the refrigeration soda water tank, the refrigeration assembly 2 also includes a fixing bracket 23 for fixing the evaporator tube 22. The fixing bracket 23 has fixing grooves 231 spaced along its length for arranging the evaporator tube 22. The fixing grooves 231 ensure that there is always a refrigeration gap 221 between adjacent evaporator tubes 22. The fixing bracket 23 includes a support plate 232 and a limiting tube 233 installed on the support plate 232 and cooperating with the support plate 232 to fix the evaporator tube 22. The support plate 232 has an L-shaped cross-section and a bent portion 2321 facing the evaporator tube 22. The limiting tube 233 is arranged in the bent portion 2321 of the support plate 232 on the side opposite to the evaporator tube 22. A fixing groove 231 is formed on the support plate 232. When the outer wall of the evaporation tube 22 abuts against the fixing groove 231, the inner wall of the evaporation tube 22 abuts against the limiting tube 233. The limiting tube 233 restricts the evaporation tube 22 within the fixing bracket 23. To further improve the vibration damping effect on the steam tube, two fixing brackets 23 for fixing the evaporation tube 22 are provided in the accommodating cavity 11.

[0038] The implementation principle of a cooling soda water tank according to an embodiment of this application is as follows: During the operation of the cooling soda water tank, carbon dioxide is input into the accommodating cavity 11 through the air inlet pipe 3, and water is input into the accommodating cavity 11 where the tank body 1 is installed through the water inlet. Due to the setting of the spray nozzle 412 at the water inlet pipe 41, the water can be input into the accommodating cavity 11 in the form of mist, which helps to improve the mixing effect of water and carbon dioxide. Then, through the cooperation between the cold water pipe 21 and the evaporation pipe 22, the soda water in the accommodating cavity 11 is cooled, and the solubility of carbon dioxide in water is increased. Finally, the cooled soda water is output from the water outlet pipe 42. There are also two one-way valves 43 at the water inlet pipe 41, which helps to provide double insurance for ensuring the stable operation of the cooling soda water tank and reduce the probability of soda water flowing out from the water inlet pipe 41.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
