Description

TECHNICAL FIELD

[0002] Existing beverage machines can prepare ice water, hot water, soda water or other carbonated beverages and flow out from a water outlet faucet to meet the needs of users to make various beverages. After the soda water path assembly is closed, the water outlet faucet stops outputting soda water, but some soda water remains in the connecting pipeline between the soda water path assembly and the water outlet faucet. Since soda water and other carbonated beverages will continue to bubble, the water outlet of the water outlet faucet will continue to drip.

[0003] To solve this problem, the existing technology generally uses the following methods:

[0004] First, cold water is used to squeeze out the remaining soda water in the water outlet faucet, but after the soda water path assembly is closed, the dripping will continue for a period of time or even drip again. Even cold water remains in the water outlet faucet, which cannot completely eliminate the problem of residual water. In addition, when the soda water is used next time, the soda water will first discharge the residual water in the water outlet faucet, and the soda water with a lower temperature will mix with the residual water with a higher temperature, thereby affecting the temperature and concentration of the soda water outlet and affecting the user's taste;

[0005] Second, the gas in the gas path is used to squeeze out the remaining soda water in the water outlet faucet, but the water outlet faucet will also spray gas while continuously outputting water, which affects the user's experience. SUMMARY

[0078] Example 1

[0079] This embodiment provides a water system for a beverage machine, suitable for beverage machines, especially soda machines. For example... Figure 1 As shown, the beverage machine's water system includes a drinking water circuit component 1, a soda water circuit component 2, and a faucet outlet circuit 3. The drinking water circuit component 1 is used to deliver drinking water, which can be treated water such as ice water, hot water, purified water, or mineral water. The soda water circuit component 2 is used to deliver soda water. One end of the faucet outlet circuit 3 is connected to the drinking water circuit component 1 and the soda water circuit component 2, and the other end is provided with a water outlet.

[0080] The beverage machine water system provided in this embodiment has a faucet outlet 3 connected to the drinking water circuit component 1 at one end, and a water outlet at the other end. The drinking water circuit component 1 provides drinking water and delivers it to the faucet outlet 3, allowing users to obtain drinking water from the outlet. The soda water circuit component 2 provides soda water and delivers it to the faucet outlet 3, allowing users to obtain soda water from the outlet. The combined effect of the drinking water circuit component 1 and the soda water circuit component 2 can meet the diverse usage needs of users.

[0081] Because after the soda water circuit component 2 delivers soda water to the faucet outlet 3, some soda water will remain in both the soda water circuit component 2 and the faucet outlet 3, causing water to continue dripping from the faucet outlet 3 even after the soda water circuit component 2 is turned off, affecting the user experience.

[0082] To address this issue, the soda water circuit component 2 provided in this embodiment is configured to selectively connect with the faucet outlet circuit 3 and the drinking water circuit component 1 to switch between a soda water output mode and a soda water recirculation mode.

[0083] The beverage machine water system provided in this embodiment allows users to connect the soda water circuit component 2 to the faucet outlet 3 to start the soda water output mode. The outlet of the faucet outlet 3 can then output soda water normally for the user to drink. If the user does not need to drink soda water, the soda water circuit component 2 is turned off, and the soda water recirculation mode is started. This connects at least one of the soda water circuit component 2 and the faucet outlet 3 to the drinking water circuit component 1. The soda water remaining in the soda water circuit component 2 and / or the faucet outlet 3 will then flow back into the drinking water circuit component 1, thus completely solving the problem of dripping water from the faucet outlet 3.

[0084] In one embodiment, such as Figure 1 As shown, the drinking water circuit assembly 1 includes a drinking water tank 11 and a water delivery circuit 12. The drinking water tank 11 is used to hold drinking water. One end of the water delivery circuit 12 is connected to the drinking water tank 11, and the other end is connected to the soda water circuit assembly 2 and the faucet outlet circuit 3.

[0085] The shape of the drinking water tank 11 includes, but is not limited to, cylindrical and cuboid structures, which can be adjusted according to actual production needs. A water outlet connector 111 is provided on the drinking water tank 11. The drinking water tank 11 is connected to the water delivery channel 12 through the water outlet connector 111. The water delivery channel 12 serves as an intermediate connection between the drinking water tank 11 and the faucet outlet channel 3, so as to deliver the drinking water in the drinking water tank 11 to the faucet outlet channel 3 through the water delivery channel 12, thereby meeting the user's drinking water needs.

[0086] Since the drinking water assembly 1 will leave some drinking water in the drinking water assembly 1 and the faucet water outlet path 3 after delivering the drinking water to the faucet water outlet path 3, the user will still find water dripping from the water outlet of the faucet water outlet path 3 even after the drinking water assembly 1 is closed, which will affect the user's experience.

[0087] To solve this problem, the drinking water assembly 1 further comprises a circulating water path 13, one end of which is in communication with the delivery water path 12 and the other end of which is in communication with the circulating joint 112 of the drinking water tank 11, for returning the drinking water and the soda water to the drinking water tank 11.

[0088] If the user needs to drink the drinking water, the drinking water assembly 1 is communicated with the faucet water outlet path 3 to start the drinking water output mode, at which time the water outlet of the faucet water outlet path 3 can normally output the drinking water for the user to drink; if the user does not need to drink the drinking water, since the two ends of the circulating water path 13 are in communication with the delivery water path 12 and the circulating joint 112 of the drinking water tank 11 respectively, the residual drinking water in the drinking water assembly 1 and the residual drinking water and soda water in the faucet water outlet path 3 will be returned to the drinking water tank 11 through the circulating water path 13, which can reduce the risk of water dripping from the water outlet of the faucet water outlet path 3.

[0089] It can be understood that if the user closes the soda water assembly 2, since the soda water assembly 2 and the drinking water assembly 1 are communicated, the residual soda water in the soda water assembly 2 and the faucet water outlet path 3 will enter the circulating water path 13 through the drinking water assembly 1 and finally be returned to the drinking water tank 11, which can not only avoid the risk of water dripping from the water outlet of the faucet water outlet path 3 after the soda water is closed, but also recycle the residual soda water for secondary use, thereby reducing the risk of waste.

[0090] It should be particularly pointed out that the circulating water path 13 can be in communication with a water source to realize the function of supplementing a large amount of water for the drinking water tank 11 from the outside through the circulating water path 13, wherein the water source can be clean water treated by a purification structure from municipal water or pure water, etc.

[0091] In one embodiment, as shown in Figure 1 the drinking water assembly 1 further comprises a drinking water valve 14 and a circulating water valve 15, the drinking water valve 14 is arranged in the delivery water path 12, and the circulating water valve 15 is arranged in the circulating water path 13.

[0092] The drinking water valve 14 is arranged in the delivery water path 12, and the drinking water valve 14 is used for opening and closing the delivery water path 12. The circulating water valve 15 is arranged in the circulating water path 13, and the circulating water valve 15 is used for opening and closing the circulating water path 13.

[0093] In the soda water output mode, both the drinking water valve 14 and the circulation water valve 15 are closed; in the soda water backflow mode, at least the circulation water valve 15 is opened. For example, in the embodiment, both the drinking water valve 14 and the circulation water valve 15 are opened.

[0094] In the soda water output mode, the soda water path assembly 2 is in an open state, and at this time, both the drinking water valve 14 and the circulation water valve 15 are in a closed state, so as to avoid the water outlet of the faucet water outlet path 3 from flowing out soda water and drinking water at the same time, which affects the concentration of the soda water, and to ensure the purity of the soda water for the user to drink.

[0095] In the soda water backflow mode, both the drinking water valve 14 and the circulation water valve 15 are in an open state, so that the soda water path assembly 2 and the faucet water outlet path 3 are communicated with the drinking water path assembly 1, and the residual soda water in the soda water path assembly 2 and the faucet water outlet path 3 flows into the drinking water tank 11 through the conveying water path 12, the drinking water valve 14 and the circulation water valve 15, so as to realize the process of backflow of the residual soda water, and to solve the problem of residual soda water dripping.

[0096] If the air pressure of the circulation water path 13 is relatively large, it is difficult to ensure the smoothness of the soda water or the drinking water backflow to the drinking water tank 11. In order to solve this problem, as shown in Figure 1 , the drinking water path provided by the embodiment further comprises a circulation pump 16, which is arranged in the circulation water path 13 and is used for backflow of the drinking water or the soda water to the drinking water tank 11.

[0097] By installing the circulation pump 16 on the circulation water path 13, under the driving action of the circulation pump 16, the drinking water or the soda water located in the circulation water path 13 is provided with a driving force for flowing, which plays a role of accelerating the backflow speed of the drinking water or the soda water, so as to ensure the thoroughness of the drinking water or the soda water backflow to the drinking water tank 11.

[0098] In an embodiment, as shown in Figure 1 , the drinking water path assembly 1 further comprises a circulation check valve 20, which is arranged in parallel with the circulation pump 16 and is connected in series with the circulation water path 13, so that the drinking water or the soda water flows back to the drinking water tank 11 through the circulation water path 13 in one direction.

[0099] If the circulating pump 16 is directly connected in series on the circulating water path 13, when the circulating pump 16 is closed, the drinking water in the delivery water path 12 is difficult to enter the drinking water tank 11 through the circulating pump 16. For this reason, the circulating check valve 20 is connected in parallel with the circulating pump 16 and in series on the circulating water path 13, so that even if the circulating pump 16 is closed, the drinking water in the delivery water path 12 can enter the drinking water tank 11 through the circulating check valve 20. In addition, if the circulating check valve 20 is not connected in parallel with the circulating pump 16, during the process of absorbing residual water from top to bottom, internal circulation will occur, and the residual water will be difficult to return to the drinking water tank 11. By connecting the circulating check valve 20 in parallel with the circulating pump 16, the function of absorbing residual water from top to bottom during the dripping process can be realized.

[0100] In one embodiment, as shown in Figure 1 The drinking water path assembly 1 further comprises a water replenishment path 17, one end of which is connected in communication with the delivery water path 12, and the other end is connected in communication with the soda water path assembly 2, for providing drinking water for the soda water path assembly 2.

[0101] With this arrangement, the water replenishment path 17 functions as an intermediate communication between the delivery water path 12 and the soda water path assembly 2, so that the delivery water path 12 provides drinking water for the soda water path assembly 2 through the water replenishment path 17, to achieve the purpose of replenishing drinking water for the soda water path.

[0102] It should be particularly noted that the delivery water path 12 comprises an inlet section and a delivery section, and the inlet section, the delivery section, the water replenishment path 17 and the circulating water path 13 can be connected in communication through a conversion joint or a four-way valve or a multi-way valve. The drinking water valve 14 is arranged in the inlet section, and closing the drinking water valve 14 can only close the inlet section, but cannot close the delivery section, at this time, the water replenishment path 17 and the circulating water path 13 can still be used normally.

[0103] Since soda water is similar to carbonated beverages, it contains a certain amount of carbon dioxide gas, so the pressure in the soda water path is relatively high, and the pressure in the water replenishment path 17 may be less than or approximately equal to that in the soda water path, which can cause the drinking water in the water replenishment path 17 to be unable to be replenished in time to the soda water path assembly 2 and return to the delivery water path 12.

[0104] In order to solve this problem, as shown in Figure 1 The drinking water path assembly 1 further comprises a booster pump 18, which is arranged in the delivery water path 12, so that the delivery water path 12 replenishes drinking water to the soda water path and outputs drinking water from the water outlet.

[0105] The booster pump 18 is installed in the delivery water path 12, and can pump the drinking water in the drinking water tank 11 to the faucet water outlet path 3 through the drinking water valve 14 and the delivery water path 12. The booster pump 18 also has the function of pumping the drinking water in the drinking water tank 11 to the drinking water tank 11 through the circulating water path 13, the circulating water valve 15 and the circulating one-way valve 20, so as to achieve water circulation and ensure the uniformity of the temperature of the drinking water in the drinking water tank 11. The booster pump 18 has multiple functions, so that the drinking water in the delivery water path 12 can be smoothly delivered to the water supplement path 17, the circulating water path 13 and the faucet water outlet path 3, and the smoothness of the delivery of the drinking water in the delivery water path 12 is improved.

[0106] The drinking water path assembly 1 also includes a water supplement one-way valve 19, which is arranged in the water supplement path 17 to allow the drinking water in the water supplement path 17 to flow to the soda water path assembly 2 in one direction.

[0107] The water supplement one-way valve 19 is arranged in the water supplement path 17, and functions to limit the one-way flow direction of the drinking water, so that the drinking water flowing out of the delivery water path 12 flows to the soda water path assembly 2 in a single direction through the water supplement path 17, to ensure the reliability of the supplement of the drinking water to the soda water path assembly 2.

[0108] In one embodiment, the soda water path assembly 2 includes a soda water tank 21 for containing soda water.

[0109] The shape of the soda water tank 21 includes but is not limited to a cylindrical shape and a cuboid shape, which can be adjusted according to actual production needs. Specifically, the soda water tank 21 and the drinking water tank 11 are coaxially arranged in a sleeved manner, i.e. the soda water tank 21 is arranged in the drinking water tank 11, which is equivalent to that the soda water tank 21 is immersed in the drinking water tank 11. The carbon dioxide gas in the soda water needs to be refrigerated, and the lower the liquid temperature, the easier the carbon dioxide gas is dissolved in the water, and the higher the concentration of the soda water, the better the taste. Therefore, arranging the soda water tank 21 in the drinking water tank 11 can refrigerate the soda water to a certain extent, so as to meet the refrigeration needs of the soda water. It can be understood that the soda water drunk by the user is usually ice soda water.

[0110] It should be particularly pointed out that the booster pump 18 can also pump the drinking water in the drinking water tank 11 to the soda water tank 21, because the pressure in the soda water tank 21 is high and the pressure in the water supplement path 17 is low, the booster pump 18 has the function of increasing the pressure in the delivery water path 12.

[0111] In one embodiment, an evaporative coil 4 is arranged in the drinking water tank 11, and the evaporative coil 4 is arranged between the drinking water tank 11 and the soda water tank 21 and surrounds the drinking water tank 11. The evaporative coil 4 simultaneously refrigerates the ice water in the drinking water tank 11 and the soda water in the soda water tank 21, so as to meet the needs of the user to drink ice water and soda water.

[0112] In one embodiment, as shown in Figures 1-3 The soda water path assembly 2 further comprises a soda delivery water path 22 and a soda valve 23. One end of the soda delivery water path 22 is in communication with the soda water tank 21, and the other end is in communication with the faucet water outlet path 3. The soda valve 23 is arranged in the soda delivery water path 22 to open and close the soda delivery water path 22.

[0113] The soda water tank 21 is provided with a liquid outlet connector 211 and a liquid inlet connector 213. The make-up water path 17 is in communication with the liquid inlet connector 213 of the soda water tank 21 to supply water to the soda water tank 21. The soda water tank 21 is in communication with the soda delivery water path 22 through the liquid outlet connector 211. The soda delivery water path 22 serves to connect the soda water tank 21 and the faucet water outlet path 3 to deliver the soda water in the soda water tank 21 to the faucet water outlet path 3 through the soda delivery water path 22, thereby meeting the needs of users to drink soda water. The soda valve 23 is arranged in the soda delivery water path 22 to open and close the soda delivery water path 22.

[0114] In the soda water output mode, the soda valve 23 is opened. At this time, the drinking water valve 14 and the circulating water valve 15 are both in a closed state to avoid the outflow of soda water and drinking water from the water outlet of the faucet water outlet path 3 at the same time, which affects the concentration of the soda water, so as to ensure the purity of the soda water for users to drink.

[0115] In the soda water backflow mode, the soda valve 23 is closed to stop the soda delivery water path 22 from outputting soda water, and the drinking water valve 14 and the circulating water valve 15 are both in an open state. The soda water path assembly 2 and the faucet water outlet path 3 are both in communication with the drinking water path assembly 1. Then, the residual soda water in the soda delivery water path 22 and the faucet water outlet path 3 flows into the drinking water tank 11 through the delivery water path 12, the drinking water valve 14, and the circulating water valve 15, thereby realizing the process of backflow of the residual soda water and solving the problem of residual soda water dripping.

[0116] It should be particularly noted that in the soda water backflow mode, the opening and closing of the drinking water valve 14 in the present embodiment are not limited, and can be adjusted according to the actual arrangement position of the drinking water valve 14. If the residual soda water needs to pass through the drinking water valve 14 to enter the drinking water tank 11 in the backflow, the circulating water valve 15, the circulating pump 16, and the drinking water valve 14 need to be opened at the same time, so that the residual soda water flows into the drinking water tank 11 through the delivery water path 12, the drinking water valve 14, and the circulating water valve 15. If the residual soda water does not need to pass through the drinking water valve 14 to enter the drinking water tank 11 in the backflow, only the circulating water valve 15 and the circulating pump 16 need to be opened at the same time. The opening and closing of the drinking water valve 14 in the soda water backflow mode in the present embodiment are not limited, and can be adjusted according to the actual production situation.

[0117] In one embodiment, as shown in Figure 1 The soda water path assembly 2 further comprises a gas cylinder 24, a gas supplement path 25 and a pressure switch 26. One end of the gas supplement path 25 is connected to the gas cylinder 24, and the other end is connected to the soda water tank 21, for delivering carbon dioxide gas to the soda water tank 21. The pressure switch 26 is arranged on the gas supplement path 25, for opening and closing the gas supplement path 25.

[0118] The gas cylinder 24 is used to contain carbon dioxide gas. The two ends of the gas supplement path 25 are connected to the gas cylinder 24 and the soda water tank 21 respectively. The gas supplement path 25 serves as an intermediate connection, for delivering carbon dioxide gas in the gas cylinder 24 to the gas supplement joint 212 of the soda water tank 21 through the gas supplement path 25, to improve the taste of the soda water. By arranging the pressure switch 26 on the gas supplement path 25, the pressure switch 26 is used to detect the pressure of the carbon dioxide gas coming out of the gas cylinder 24. When the pressure switch 26 detects that the pressure of the carbon dioxide gas is very small, at this time the gas cylinder 24 is in a state of no carbon dioxide gas or close to no carbon dioxide gas, then the pressure switch 26 delivers this signal to the controller, and the controller sends a signal to remind that the gas cylinder 24 needs to be replaced.

[0119] In one embodiment, the soda water path assembly 2 further comprises a gas pressure limiting valve 27 and a gas supplement one-way valve 28. The gas pressure limiting valve 27 is arranged on the gas supplement path 25, for limiting the pressure in the gas supplement path 25, to avoid the risk of excessive pressure in the gas supplement path 25. The gas supplement one-way valve 28 is arranged on the gas supplement path 25, for limiting the flow direction of carbon dioxide in the gas supplement path 25, so that the carbon dioxide output from the gas cylinder 24 is delivered to the soda water tank 21 through the gas supplement path 25 in a single direction.

[0120] In one embodiment, the beverage machine water path system further comprises a controller, which is electrically connected to the drinking water valve 14, the circulating water valve 15, the circulating pump 16, the soda valve 23 and the pressure switch 26 respectively. The controller can receive the opening and closing signals of these valves, and control the actions of these valves and the opening and closing of other components according to these opening and closing signals, to ensure the reliability of the switching between the two modes.

[0121] In one embodiment, as shown in Figure 2 The beverage machine water path system further comprises a water path board 5, and the drinking water path assembly 1, the soda water path assembly 2 and the faucet water outlet path 3 are integrated on the water path board 5.

[0122] By integrating the water paths and valve structures in each water path assembly on the water path board 5 to form an overall structure, the footprint is small, the overall movement is convenient, and the risk of connecting multiple pipes is reduced. At the same time, the production cost is saved, and the sealing effect of the beverage machine water path system is improved.

[0123] The embodiment also provides a beverage machine, which comprises the beverage machine water system.

[0124] If a user needs to drink soda water, the soda water output mode is started, the soda water path component 2 is communicated with the faucet water outlet path 3, the water outlet of the faucet water outlet path 3 can normally output soda water for the user to drink; if the user does not need to drink soda water, the soda water path component 2 is closed, the soda water backflow mode is started, the soda water path component 2 and the drinking water path component 1 are communicated, and then the residual soda water in the soda water path component 2 and the faucet water outlet path 3 can flow back to the drinking water path component 1, thereby completely solving the problem of water dripping from the water outlet of the faucet water outlet path 3.

[0125] The embodiment also provides a beverage machine water system control method for controlling the beverage machine water system, as shown in the following. Figures 4-5 The beverage machine water system control method comprises the following steps.

[0126] In the soda water output mode, the soda water path component 2 is communicated with the faucet water outlet path 3, so that the soda water is conveyed to the faucet water outlet path 3 through the soda water path component 2.

[0127] In the soda water backflow mode, at least one of the soda water path component 2 and the faucet water outlet path 3 is communicated with the drinking water path component 1, so that the residual soda water in the faucet water outlet path 3 and / or the soda water path component 2 flows back to the drinking water path component 1.

[0128] The embodiment also provides a beverage machine water system control method, if a user needs to drink soda water, the soda water output mode is started, the soda water path component 2 is communicated with the faucet water outlet path 3, the water outlet of the faucet water outlet path 3 can normally output soda water for the user to drink.

[0129] Compared with the prior art of squeezing out residual soda water with cold water after closing the soda water, in the soda water backflow mode, the residual soda water flows back after the soda water path component 2 is closed, the water outlet of the faucet water outlet path 3 immediately stops water output and does not drip, the soda water is closed more completely, and the user experience is better. At the same time, since the soda water path component 2 and / or the faucet water outlet path 3 completely discharge the soda water, when the soda water is output again, the mixing of residual soda water at a higher temperature and new soda water just output is avoided, the concentration and temperature of the soda water are ensured, and the taste of the soda water is better. Compared with the prior art of squeezing out residual soda water with gas after closing the soda water, the faucet water outlet path 3 does not continuously output water and does not spray gas, and the user experience is improved.

[0130] As shown in the following. Figure 4As shown, in the soda water output mode, the soda valve 23 is opened, the drinking water valve 14 and the circulating water valve 15 are closed, and the faucet water outlet path 3 is only communicated with the soda water path assembly 2.

[0131] When the soda valve 23 is opened, the soda water in the soda water tank 21 is delivered to the faucet water outlet path 3, so as to meet the user's need of drinking soda water. At this time, the drinking water valve 14 and the circulating water valve 15 are both in the closed state, so as to avoid the situation that the outlet of the faucet water outlet path 3 flows out soda water and drinking water at the same time, which affects the concentration of the soda water, so as to ensure the purity of the soda water.

[0132] Specifically, in the soda water backflow mode, the soda valve 23 is closed, and the drinking water valve 14 and the circulating water valve 15 are controlled to be opened. The residual soda water in the faucet water outlet path 3 and / or the soda water path assembly 2 flows back to the drinking water path assembly 1 through the drinking water valve 14 and the circulating water valve 15 due to gravity.

[0133] If the soda valve 23 is closed, the soda delivery water path 22 stops outputting soda water to the faucet water outlet path 3. The drinking water valve 14 and the circulating water valve 15 can be both in the opened state, so that the soda delivery water path 22 and the faucet water outlet path 3 are both communicated with the delivery water path 12. Then, the residual soda water in the soda delivery water path 22 and the faucet water outlet path 3 flows into the drinking water tank 11 through the delivery water path 12 and the circulating water valve 15, so as to realize the process of backflow of the residual soda water, so as to solve the problem of residual soda water dripping.

[0134] In one embodiment, the soda water backflow mode further includes the following steps:

[0135] After the soda valve 23 is closed, the circulating pump 16 is controlled to be started;

[0136] The actual running time of the circulating pump 16 is obtained;

[0137] If the actual running time of the circulating pump 16 is greater than or equal to the preset time, the circulating pump 16, the drinking water valve 14 and the circulating water valve 15 are controlled to be closed.

[0138] Specifically, after the controller receives the closing signal of the soda valve 23, the drinking water valve 14 and the circulating water valve 15 are immediately opened, and the circulating pump 16 is simultaneously started, under the driving action of the circulating pump 16, the residual soda water flows into the drinking water tank 11 through the delivery water path 12 and the circulating water valve 15, so as to accelerate the return speed of the soda water, and ensure the thoroughness of the soda water returning to the drinking water tank 11. After obtaining the actual running time of the circulating pump 16, the actual running time of the circulating pump 16 is compared with the preset time. If the actual running time of the circulating pump 16 is greater than or equal to the preset time, it means that the residual soda water has been completely returned to the drinking water tank 11. At this time, the circulating pump 16, the drinking water valve 14 and the circulating water valve 15 are controlled to be closed, so as to avoid unnecessary energy waste.

[0139] Embodiment Two

[0140] This embodiment is similar to Embodiment One, and the difference is only that the faucet water outlet path 3 and other details are different.

[0141] As shown in Figure 6 , the beverage machine water path system provided by this embodiment further comprises a faucet one-way valve 31, which is arranged in the faucet water outlet path 3, so that the drinking water or soda water flows to the water outlet in one direction.

[0142] The beverage machine water path system provided by this embodiment arranges the faucet one-way valve 31 in the faucet water outlet path 3, which is used to limit the flow direction of the drinking water or soda water in the faucet water outlet path 3. When the user obtains the drinking water or soda water at the water outlet, the user can also avoid the external gas, impurities and the like entering the drinking water path assembly 1 and the soda water path assembly 2 through the faucet water outlet path 3, thereby reducing the pollution of the drinking water in the drinking water tank 11 and the pollution of the soda water in the soda water tank 21, and improving the cleanliness of the drinking water tank 11 and the soda water tank 21.

[0143] In one embodiment, as shown in Figure 6 , the beverage machine water path system further comprises an air passage 6 and a gas supplement one-way valve 28. One end of the air passage 6 is in communication with the drinking water tank 11, and the other end is in communication with the faucet water outlet path 3, the delivery water path 12 and the circulating water path 13, respectively. The gas supplement one-way valve 28 is arranged in the air passage 6, and is used to balance the air pressure in the drinking water tank 11.

[0144] As shown in Figure 7 , in the soda water output mode, since the air passage 6 is provided with the gas supplement one-way valve 28, the gas supplement one-way valve 28 can only output and cannot input in one direction, so as to prevent the soda water output from the soda delivery water path 22 from entering the soda water tank 21 through the air passage 6.

[0145] As shown in Figure 8As shown, in the soda water recirculation mode, if there is no vent 6 and air replenishment check valve 28, when the circulation pump 16 sucks back the residual soda water in the faucet outlet 3, the air pressure will cause the valve ball of the faucet check valve 31 to fit tightly against the valve seat, thus blocking the faucet outlet 3 and keeping the internal space of the drinking water tank 11 sealed. Due to the air pressure, the circulation pump 16 has difficulty sucking the residual soda water back into the soda water tank 21. Therefore, a vent 6 is provided between the drinking water tank 11 and the faucet outlet 3. When the circulation pump 16 sucks back the residual water in the faucet outlet 3, the circulation pump 16 will also simultaneously suck back the valve ball of the air replenishment check valve 28, so that the valve ball and valve seat of the air replenishment check valve 28 are misaligned, and the drinking water tank 11 is no longer sealed. Since the drinking water tank 11 is in a ventilated state, the circulation pump 16 can draw back the residual soda water in the faucet outlet 3 into the drinking water tank 11, which facilitates the reliability of residual soda water back-drawing.

[0146] Understandably, the use of the air replenishment check valve 28 is simple in structure, reduces electronic logic control programs, is easy to use, and has relatively low production costs.

[0147] Understandably, in some other implementations, the air replenishment check valve 28 can be replaced with a solenoid valve for control.

[0148] It should be noted that the circulation check valve 20 can be connected in parallel with the circulation pump 16 and then connected in series with the circulation water circuit 13. Alternatively, the circulation check valve 20 can be omitted. For example, a self-priming pump 201 can be connected externally between the top and bottom of the drinking water tank 11 to pump the drinking water in the drinking water tank 11 back to the drinking water tank 11, thereby realizing the self-circulation of the drinking water tank 11.

[0149] like Figures 7-8 As shown, this embodiment also provides a water circuit control method for a beverage machine, including the following steps:

[0150] In the soda water output mode, control to open soda valve 23, close drinking water valve 14 and circulating water valve 15, so that faucet outlet 3 is only connected to soda water circuit component 2.

[0151] In the soda water recirculation mode, the soda valve 23 is closed and the circulating water valve 15 and circulating pump 16 are opened, so that the residual soda water in the faucet outlet 3 and the soda water circuit assembly 2 flows back to the drinking water circuit through the circulating water valve 15.

[0152] When the circulating water valve 15 and circulating pump 16 are opened, the faucet check valve 31 in the faucet outlet 3 will block the water outlet, and the air replenishment check valve 28 in the air passage 6 will open, allowing the residual soda water in the faucet outlet 3 and the residual water in the delivery water passage 12 to flow back. If the actual running time of the circulating pump 16 is greater than or equal to the preset time, it means that the backflow time has been long enough, and the circulating water valve 15 and circulating pump 16 will be closed to reduce waste.

[0153] It should be noted that in the soda water recirculation mode, this embodiment does not limit the opening and closing of the drinking water valve 14. The position of the drinking water valve 14 can be adjusted according to its actual location. If the residual soda water needs to pass through the drinking water valve 14 to enter the drinking water tank 11 during the recirculation, then the circulating water valve 15, the circulating pump 16, and the drinking water valve 14 need to be opened simultaneously, allowing the residual soda water to flow into the drinking water tank 11 through the water supply path 12, the drinking water valve 14, and the circulating water valve 15. If the residual soda water does not need to pass through the drinking water valve 14 to enter the drinking water tank 11 during the recirculation, then only the circulating water valve 15 and the circulating pump 16 need to be opened simultaneously. This embodiment does not limit the opening and closing of the drinking water valve 14 in the soda water recirculation mode; it can be adjusted according to actual production conditions.
