Example 1

The embodiment provides a waterway system of a beverage machine, which is suitable for the beverage machine, in particular to a soda machine. As shown in fig. 1, the waterway system of the beverage maker comprises a drinking waterway assembly 1, a soda waterway assembly 2 and a tap water outlet channel 3, wherein the drinking waterway assembly 1 is used for conveying drinking water, the drinking water can be ice water, hot water, purified water or mineral water and other treated water, the soda waterway assembly 2 is used for conveying soda water, one end of the tap water outlet channel 3 is communicated with the drinking waterway assembly 1 and the soda waterway assembly 2, and a water outlet is formed in the other end of the tap water outlet channel 3.

The beverage machine waterway system that this embodiment provided, the one end of tap play water route 3 with drink waterway assembly 1, the other end is provided with the delivery port, drink waterway assembly 1 and provide the drinking water, drink waterway assembly 1 and can carry the drinking water to tap play water route 3, make the user obtain the drinking water at the delivery port. Soda water is provided by soda water circuit assembly 2. Soda water circuit assembly 2 is capable of delivering soda water to faucet spout 3 so that a user may obtain soda water at the water outlet. Under the combined action of the drinking water path component 1 and the soda water path component 2, the multifunctional drinking water path can meet the diversified use requirements of users.

Because some soda water remains in the soda water path assembly 2 and the tap water outlet path 3 after the soda water path assembly 2 is conveyed to the tap water outlet path 3, even if the soda water path assembly 2 is closed, the soda water can continuously drip from the water outlet of the tap water outlet path 3, and the use feeling of a user is affected.

To address this problem, the present embodiment provides a soda water circuit assembly 2 configured to selectively communicate with the tap water outlet circuit 3 and the drinking water circuit assembly 1 to switch between a soda water output mode and a soda water return mode.

In the water path system of the beverage machine provided by the embodiment, if a user needs to drink the soda water, the soda water path assembly 2 is communicated with the tap water outlet path 3, a soda water output mode is started, and the water outlet of the tap water outlet path 3 can normally output the soda water for the user to drink the soda water; if the user does not need to drink the soda water, the soda water path assembly 2 is closed, a soda water reflux mode is started, at least one of the soda water path assembly 2 and the tap water outlet path 3 is communicated with the drinking water path assembly 1, and the soda water remained in the soda water path assembly 2 and/or the tap water outlet path 3 can reflux into the drinking water path assembly 1, so that the problem of water dripping of a water outlet of the tap water outlet path 3 is thoroughly solved.

In one embodiment, as shown in fig. 1, the drinking water path assembly 1 includes a drinking water tank 11, a delivery water path 12, the drinking water tank 11 for containing drinking water, one end of the delivery water path 12 being in communication with the drinking water tank 11, and the other end being in communication with the soda water path assembly 2 and the tap water outlet path 3.

The appearance of the drinking water tank 11 comprises, but is not limited to, a cylindrical and cuboid structure, and can be adjusted according to actual production needs, a water outlet joint 111 is arranged on the drinking water tank 11, the drinking water tank 11 is communicated with a conveying waterway 12 through the water outlet joint 111, the conveying waterway 12 plays a role in communicating the middle of the drinking water tank 11 and the tap water outlet waterway 3, so that drinking water in the drinking water tank 11 is conveyed to the tap water outlet waterway 3 through the conveying waterway 12, and the drinking water drinking needs of users are met.

Because drinking water path assembly 1 can remain partial drinking water in drinking water path assembly 1 and tap water path 3 after drinking water is delivered to tap water path 3, even if drinking water path assembly 1 is closed, the water outlet of tap water path 3 can continuously drip water, and the use feeling of users is affected.

To solve this problem, the drinking water path assembly 1 further includes a circulation water path 13, one end of the circulation water path 13 being communicated with the delivery water path 12, and the other end being communicated with the drinking water tank 11 for returning drinking water and soda water to the drinking water tank 11.

If the user needs to drink the drinking water, the drinking water channel assembly 1 is communicated with the tap water outlet channel 3 to start a drinking water output mode, and at the moment, the water outlet of the tap water outlet channel 3 can normally output the drinking water for the user to drink; if the user does not need to drink the drinking water, as the two ends of the circulating waterway 13 are respectively communicated with the conveying waterway 12 and the circulating joint 112 of the drinking water tank 11, the residual drinking water in the drinking waterway assembly 1 and the residual drinking water and soda water in the tap water outlet waterway 3 can flow back into the drinking water tank 11 through the circulating waterway 13, and the risk of dripping water from the water outlet of the tap water outlet waterway 3 can be reduced.

It will be appreciated that if the user closes the soda water path assembly 2, since the soda water path assembly 2 is in communication with the drinking water path assembly 1, residual soda water in the soda water path assembly 2 and the tap water outlet path 3 will enter the circulating water path 13 through the drinking water path assembly 1 and finally flow back into the drinking water tank 11, and the risk of dripping water from the water outlet of the tap water outlet path 3 after the soda water is closed can be avoided, and the residual soda water can be recovered and reused, thereby reducing the risk of waste.

It should be noted that, the circulation waterway 13 may be connected to a water source, so as to realize the effect of supplementing a large amount of water to the drinking water tank 11 through the circulation waterway 13, where the water source may be clean water after municipal water is treated by the purification structure, or purified water.

In one embodiment, as shown in fig. 1, the drinking water circuit assembly 1 further includes a drinking water valve 14 and a circulation water valve 15, the drinking water valve 14 being disposed in the delivery water circuit 12, and the circulation water valve 15 being disposed in the circulation water circuit 13.

A drinking water valve 14 is arranged on the conveying waterway 12, and the drinking water valve 14 is used for opening and closing the conveying waterway 12. A circulation water valve 15 is provided in the circulation water path 13, and the circulation water valve 15 is used for opening and closing the circulation water path 13.

Wherein, in the soda water output mode, both the drinking water valve 14 and the circulation water valve 15 are closed; in the soda water return mode, at least the circulation water valve 15 is open. For example: in this embodiment both the drinking water valve 14 and the circulation water valve 15 are open.

In the soda water output mode, the soda water path assembly 2 is in an open state, and the drinking water valve 14 and the circulating water valve 15 are in a closed state at the moment, so that the phenomenon that the concentration of the soda water is influenced due to the fact that the soda water and the drinking water flow out of the water outlet of the tap water path 3 at the same time is avoided, and the purity of the soda water drunk by a user is ensured.

When in the soda water reflux mode, the drinking water valve 14 and the circulating water valve 15 are both in an open state, so that the soda water path assembly 2 and the tap water outlet path 3 are both communicated with the drinking water path assembly 1, and residual soda water in the soda water path assembly 2 and the tap water outlet path 3 flows into the drinking water tank 11 after passing through the conveying water path 12, the drinking water valve 14 and the circulating water valve 15, thereby realizing the process of reserving soda water reflux and solving the problem of residual soda water dripping.

If the air pressure of the circulation water path 13 is relatively large, it is difficult to ensure the smoothness of the return of the soda water or the drinking water to the drinking water tank 11. In order to solve this problem, as shown in fig. 1, the drinking water path provided in the present embodiment further includes a circulation pump 16, and the circulation pump 16 is disposed in the circulation water path 13 for returning the drinking water or soda water to the drinking water tank 11.

By installing the circulating pump 16 on the circulating waterway 13, the driving force of the flowing is provided for the drinking water or soda water in the circulating waterway 13 under the driving action of the circulating pump 16, and the effect of accelerating the reflux speed of the drinking water or soda water is achieved, so that the thoroughness of the reflux of the drinking water or soda water to the drinking water tank 11 is ensured.

In one embodiment, as shown in fig. 1, the drinking water path assembly 1 further includes a circulation check valve 20, and the circulation check valve 20 is connected in parallel with the circulation pump 16 and then connected in series to the circulation water path 13, so that the drinking water or soda water flows back to the drinking water tank 11 in one way through the circulation water path 13.

If the circulation pump 16 is directly connected in series to the circulation water path 13, it is difficult for the drinking water in the delivery water path 12 to enter the drinking water tank 11 through the circulation pump 16 when the circulation pump 16 is turned off. For this reason, the circulation check valve 20 is provided in parallel with the circulation pump 16 and then connected in series to the circulation water path 13, so that even if the circulation pump 16 is turned off, the drinking water in the water path 12 can enter the drinking water tank 11 through the circulation check valve 20. In addition, if the circulating check valve 20 is not connected in parallel with the circulating pump 16, the internal circulation is caused in the process of absorbing the residual water from top to bottom, the residual water is difficult to flow back to the drinking water tank 11, and the circulating check valve 20 is connected in parallel with the circulating pump 16, so that the effect of absorbing the residual water from top to bottom in the dripping process can be realized.

In one embodiment, as shown in fig. 1, the drinking water circuit assembly 1 further includes a make-up water circuit 17, one end of the make-up water circuit 17 being in communication with the delivery water circuit 12 and the other end being in communication with the soda water circuit assembly 2 for providing drinking water to the soda water circuit assembly 2.

With this arrangement, the water make-up channel 17 serves as an intermediate communication between the water transfer channel 12 and the soda water assembly 2, so that the water transfer channel 12 supplies drinking water to the soda water assembly 2 through the water make-up channel 17, thereby achieving the purpose of supplementing drinking water to the soda water.

It should be noted that, the water supply channel 12 includes a water inlet section and a water supply section, and the water inlet section, the water supply section, the water compensating channel 17 and the circulating water channel 13 may be communicated through a switching joint or a four-way or multi-way valve. The drinking water valve 14 is arranged at the water inlet section, and when the drinking water valve 14 is closed, the water inlet section can be closed only, and the conveying section can not be closed, at the moment, the water supplementing channel 17 and the circulating channel 13 can still be normally used.

Since soda water is similar to carbonated beverages and contains a certain amount of carbon dioxide gas, the pressure in the soda water circuit is relatively high, and there may be a make-up water circuit 17 with a pressure less than or approximately equal to that of the soda water circuit, so that the drinking water in the make-up water circuit 17 cannot be timely fed to the soda water circuit assembly 2 and returned to the delivery water circuit 12.

To solve this problem, as shown in fig. 1, the drinking water path assembly 1 further includes a booster pump 18, wherein the booster pump 18 is disposed on the delivery water path 12, so that the delivery water path 12 supplements drinking water to the soda water path and outputs drinking water to the water outlet.

A booster pump 18 is installed in the delivery waterway 12, and the booster pump 18 can pump water in the drinking water tank 11 out through the drinking water valve 14 and the delivery waterway 12 to the tap water outlet waterway 3. The booster pump 18 also has a function of pumping the drinking water in the drinking water tank 11 to the drinking water tank 11 through the circulation waterway 13, the circulation water valve 15 and the circulation check valve 20, so as to achieve the purposes of water circulation and ensuring the uniformity of the upper and lower temperatures of the drinking water in the drinking water tank 11. The booster pump 18 has various functions, so that the drinking water in the water conveying channel 12 can be smoothly conveyed to the water supplementing channel 17, the circulating channel 13 and the tap water outlet channel 3, and the smoothness of the drinking water conveying channel 12 in conveying is improved.

The drinking water path assembly 1 further comprises a water supplementing one-way valve 19, wherein the water supplementing one-way valve 19 is arranged on the water supplementing path 17, so that drinking water in the water supplementing path 17 flows to the soda water path assembly 2 in one direction.

The water supplementing one-way valve 19 is arranged on the water supplementing channel 17, and the water supplementing one-way valve 19 plays a role in limiting the one-way flowing direction of the drinking water, so that the drinking water flowing out of the conveying water channel 12 flows into the soda water channel assembly 2 along a single direction after passing through the water supplementing channel 17, and the reliability of supplementing the soda water channel assembly 2 with the drinking water is ensured.

In one embodiment, soda water circuit assembly 2 includes soda water tank 21, soda water tank 21 for containing soda water.

The shape of the soda water tank 21 includes, but is not limited to, a cylindrical shape and a rectangular parallelepiped shape, and can be adjusted according to actual production requirements. Specifically, the soda water tank 21 and the drinking water tank 11 are mutually sleeved and coaxially arranged, namely, the soda water tank 21 is arranged in the drinking water tank 11, which is equivalent to the fact that the soda water tank 21 is soaked in the drinking water tank 11, carbon dioxide gas in soda water is dissolved in water to be refrigerated, the lower the liquid temperature is, the more easily the carbon dioxide gas is dissolved in water, and the higher the concentration of the soda water is, the better the taste is. Therefore, the soda water tank 21 is arranged in the drinking water tank 11, and plays a role of soda water refrigeration to a certain extent so as to meet the demand of soda water refrigeration. It will be appreciated that the soda consumed by the user is typically ice soda.

It should be noted that the booster pump 18 may pump the drinking water in the drinking water tank 11 to the soda water tank 21, and the booster pump 18 may increase the air pressure in the water supply channel 12 due to the large air pressure in the soda water tank 21 and the small air pressure in the water supply channel 17.

In one embodiment, an evaporation coil 4 is disposed within the potable water tank 11, the evaporation coil 4 being disposed between the potable water tank 11 and the soda water tank 21 and around the potable water tank 11, the evaporation coil 4 simultaneously cooling both the ice water in the potable water tank 11 and the soda water of the soda water tank 21 to meet the needs of the user for drinking both ice water and soda water.

In one embodiment, as shown in fig. 1-3, soda water circuit assembly 2 further includes a soda transfer waterway 22 and a soda valve 23, with one end of soda transfer waterway 22 being in communication with soda water tank 21 and the other end being in communication with tap water outlet waterway 3. The soda valve 23 is disposed in the soda delivery waterway 22, and is used for opening and closing the soda delivery waterway 22.

The soda water tank 21 is provided with a liquid outlet joint 211 and a liquid inlet joint 213, and the water supplementing path 17 is communicated with the liquid inlet joint 213 of the soda water tank 21 so as to supplement water for the soda water tank 21. The soda water tank 21 is communicated with the soda delivery waterway 22 through the liquid outlet joint 211, and the soda delivery waterway 22 plays a role in communicating between the soda water tank 21 and the tap water outlet waterway 3 so as to deliver soda water in the soda water tank 21 to the tap water outlet waterway 3 through the soda delivery waterway 22, thereby meeting the requirements of users for drinking the soda water. A soda valve 23 is installed in the soda transfer waterway 22, and the soda valve 23 is used for opening and closing the soda transfer waterway 22.

In soda water output mode, soda valve 23 is open.

It should be noted that, in the soda water backflow mode, the opening and closing of the drinking water valve 14 is not limited in this embodiment, and can be adjusted according to the actual setting position of the drinking water valve 14, if the residual soda water needs to pass through the drinking water valve 14 during the backflow and then enter the drinking water tank 11, then the circulation water valve 15, the circulation pump 16 and the drinking water valve 14 need to be opened simultaneously, so that the residual soda water flows into the drinking water tank 11 after passing through the delivery waterway 12, the drinking water valve 14 and the circulation water valve 15; if the residual soda water can enter the drinking water tank 11 without passing through the drinking water valve 14 in the backflow process, the circulating water valve 15 and the circulating pump 16 are only required to be simultaneously opened. The opening and closing of the drinking water valve 14 in the soda water reflux mode is not limited in this embodiment, and can be adjusted according to actual production conditions.

In one embodiment, as shown in fig. 1, the soda water path assembly 2 further includes a gas bottle 24, a gas supplementing pipe 25, and a pressure switch 26, wherein one end of the gas supplementing pipe 25 is communicated with the gas bottle 24, the other end is communicated with the soda water tank 21, and is used for conveying carbon dioxide gas to the soda water tank 21, and the pressure switch 26 is arranged in the gas supplementing pipe 25, and is used for opening and closing the gas supplementing pipe 25.

The embodiment also provides a beverage machine, which comprises the beverage machine waterway system.

In the beverage machine provided by the embodiment, if a user needs to drink the soda water, a soda water output mode is started to enable the soda water path assembly 2 to be communicated with the tap water outlet path 3, and the soda water can be normally output from the water outlet of the tap water outlet path 3 for the user to drink; if the user does not need to drink the soda water, the soda water path assembly 2 is closed, a soda water backflow mode is started, so that the soda water path assembly 2 is communicated with the drinking water path assembly 1, and residual soda water in the soda water path assembly 2 and the tap water outlet path 3 can flow back into the drinking water path assembly 1, so that the problem of water dripping at the water outlet of the tap water outlet path 3 is thoroughly solved.

The embodiment also provides a control method of the water channel system of the beverage machine, which is used for controlling the water channel system of the beverage machine, as shown in fig. 4-5, and comprises the following steps:

in the soda water output mode, the soda water path assembly 2 is communicated with the tap water outlet path 3, so that the soda water is conveyed to the tap water outlet path 3 through the soda water path assembly 2;

in the soda water return mode, at least one of the soda water circuit assembly 2 and the tap water circuit 3 is communicated with the drinking water circuit assembly 1, so that residual soda water in the tap water circuit 3 and/or the soda water circuit assembly 2 is returned to the drinking water circuit assembly 1.

The embodiment also provides a control method of the waterway system of the beverage machine, if a user needs to drink the soda water, a soda water output mode is started, so that the soda water path assembly 2 is communicated with the faucet water outlet channel 3, and the water outlet of the faucet water outlet channel 3 can normally output the soda water for the user to drink.

Compared with the existing mode of extruding residual soda water by cold water after closing the soda water, the soda water backflow mode provided by the embodiment can backflow the residual soda water after closing the soda water path assembly 2, the water outlet of the faucet water path 3 can stop water outlet immediately and can not drip water, the soda water closing can be more thorough, and the user experience is better. Meanwhile, as the soda water is thoroughly discharged by the soda water channel assembly 2 and/or the tap water outlet channel 3, when the soda water is output again, the concentration and the temperature of the soda water are prevented from being influenced by mixing residual soda water with fresh soda water which is just discharged, the new soda water flowing out of the tap water outlet channel 3 is ensured, and the taste of the soda water is better. Compared with the existing mode of extruding residual soda water by using gas after closing the soda water, the continuous water outlet and air injection of the tap water outlet channel 3 can not occur, and the use feeling of a user is improved.

As shown in fig. 4, in the soda water output mode, the soda valve 23 is controlled to be opened, the drinking water valve 14 and the circulation water valve 15 are closed, and the tap water outlet path 3 is communicated with the soda water path assembly 2 only.

Because the soda valve 23 is opened, soda water in the soda water tank 21 is conveyed to the tap water outlet channel 3, so that the need of a user for drinking the soda water is met, and at the moment, the drinking water valve 14 and the circulating water valve 15 are both in a closed state, so that the phenomenon that the concentration of the soda water is influenced due to the fact that the soda water and the drinking water simultaneously flow out of the water outlet of the tap water outlet channel 3 is avoided, and the purity of the soda water drunk by the user is ensured.

Specifically, in the soda water return mode, the soda valve 23 is closed, the drinking water valve 14 and the circulating water valve 15 are controlled to be opened, and the soda water remaining in the tap water outlet channel 3 and/or the soda water channel assembly 2 is returned to the drinking water channel assembly 1 through the drinking water valve 14 and the circulating water valve 15 due to gravity.

If the soda valve 23 is closed, the soda delivery waterway 22 stops outputting soda water to the tap water outlet waterway 3, and the drinking water valve 14 and the circulating water valve 15 can be both in an open state, so that the soda delivery waterway 22 and the tap water outlet waterway 3 are both communicated with the delivery waterway 12, and the soda water remained in the soda delivery waterway 22 and the tap water outlet waterway 3 flows into the drinking water tank 11 after passing through the delivery waterway 12 and the circulating water valve 15, so that the process of reserving soda water reflux is realized, and the problem of residual soda water dripping is solved.

In one embodiment, the soda water reflux mode further comprises the steps of:

after closing and opening the soda valve 23, controlling the start of the circulation pump 16;

acquiring the actual running time of the circulation pump 16;

if the actual operation time of the circulation pump 16 is equal to or longer than the preset time, the circulation pump 16, the drinking water valve 14 and the circulation water valve 15 are controlled to be closed.

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 controlled to be opened immediately, and the circulating pump 16 is controlled to be started at the same time, so that residual soda water flows into the drinking water tank 11 after passing through the conveying waterway 12 and the circulating water valve 15 under the driving action of the circulating pump 16, the function of accelerating the reflux speed of the soda water is achieved, and the thoroughness of the reflux of the soda water to the drinking water tank 11 is ensured. After the actual operation time of the circulation pump 16 is obtained, the actual operation time of the circulation pump 16 is compared with the preset time, and if the actual operation time of the circulation pump 16 is equal to or longer than the preset time, the residual soda water is completely returned to the drinking water tank 11, and at this time, the circulation pump 16, the drinking water valve 14 and the circulation water valve 15 are controlled to be closed, so that unnecessary energy waste is avoided.

Example two

This embodiment is similar to the embodiment, and differs only in other details of the tap water outlet 3.

As shown in fig. 6, the waterway system of the beverage maker provided in this embodiment further includes a faucet check valve 31, and the faucet check valve 31 is disposed in the faucet waterway 3, so that the drinking water or soda water flows to the water outlet in one direction.

The beverage machine waterway system provided by the embodiment sets the faucet check valve 31 in the faucet water outlet channel 3 for limiting the flowing direction of the drinking water or soda water in the faucet water outlet channel 3, so that a user can conveniently obtain the drinking water or soda water and other beverages at the water outlet, and meanwhile, the outside gas, impurities and the like can be prevented from entering the drinking waterway assembly 1 and the soda water channel assembly 2 through the faucet water outlet channel 3, thereby reducing the pollution to the drinking water in the drinking water tank 11 and 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.

In one embodiment, as shown in fig. 6, the water path system of the beverage maker further comprises a ventilation path 6 and a gas supplementing one-way valve 28, wherein one end of the ventilation path 6 is communicated with the drinking water tank 11, and the other end is respectively communicated with the tap water outlet path 3, the delivery water path 12 and the circulating water path 13. The air-supplementing check valve 28 is provided in the air-passing path 6 for balancing the air pressure in the drinking-water tank 11.

As shown in fig. 7, in the soda water output mode, since the air-supply check valve 28 is provided in the air-passage 6, the air-supply check valve 28 stops water in a single direction, and only can be discharged, but cannot be introduced, so that soda water output from the soda water-conveying passage 22 is prevented from entering the soda water tank 21 through the air-passage 6.

As shown in fig. 8, in the soda water recirculation mode, if the ventilation passage 6 and the air supply check valve 28 are not provided, when residual soda water remaining in the tap water outlet passage 3 is sucked back by the circulation pump 16, the air pressure will attract the valve ball of the tap check valve 31 to closely contact with the valve seat, so that the tap water outlet passage 3 is blocked, and the internal space of the drinking water tank 11 is in a closed state. Depending on the air pressure, the circulation pump 16 has difficulty sucking back the remaining soda water into the soda tank 21. Therefore, a ventilation channel 6 is arranged between the drinking water tank 11 and the tap water outlet channel 3, and when the circulating pump 16 sucks residual water in the tap water outlet channel 3, the circulating pump 16 sucks the valve ball of the air supplementing one-way valve 28 back at the same time so as to stagger the valve ball and the valve seat of the air supplementing one-way valve 28, so that the drinking water tank 11 is not in a closed state any more. Because the drinking water tank 11 is in the ventilation state, the circulating pump 16 can suck back the residual soda water in the tap water outlet channel 3 into the drinking water tank 11, so that the reliability of the residual soda water suck-back is facilitated.

It can be appreciated that the air-supplementing one-way valve 28 is simple in structure, convenient to use and low in production cost, and reduces electronic logic control programs.

It will be appreciated that in some other implementations, the air make-up check valve 28 may be controlled by a solenoid valve instead.

It should be noted that, the circulating check valve 20 may be connected in parallel with the circulating pump 16 and then connected in series with the circulating waterway 13, or the circulating check valve 20 may not be provided, for example, a self-priming pump 201 may be externally connected between the top and the 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, so as to realize self-circulation of the drinking water tank 11.

As shown in fig. 7-8, the present embodiment further provides a water path control method of a beverage machine, including the following steps:

in the soda water output mode, the soda valve 23 is controlled to be opened, the drinking water valve 14 and the circulating water valve 15 are closed, and the tap water outlet channel 3 is communicated with the soda water channel assembly 2 only;

in the soda water reflux mode, the soda valve 23 is controlled to be closed, the circulating water valve 15 and the circulating pump 16 are controlled to be opened, and residual soda water in the tap water outlet channel 3 and the soda water channel assembly 2 is refluxed to the drinking water channel through the circulating water valve 15.

When the circulation water valve 15 and the circulation pump 16 are opened, the water outlet is blocked by the tap one-way valve 31 in the tap water outlet channel 3, and the air supplementing one-way valve 28 in the air channel 6 is opened, so that the residual soda water in the tap water outlet channel 3 and the residual water in the delivery water channel 12 are refluxed. If the actual operation time of the circulation pump 16 is equal to or longer than the preset time, which means that the return time is long enough, the circulation water valve 15 and the circulation pump 16 are closed to reduce waste.

It should be noted that, in the soda water backflow mode, the opening and closing of the drinking water valve 14 is not limited in this embodiment, and can be adjusted according to the actual setting position of the drinking water valve 14, if the residual soda water needs to pass through the drinking water valve 14 during the backflow and then enter the drinking water tank 11, then the circulation water valve 15, the circulation pump 16 and the drinking water valve 14 need to be opened simultaneously, so that the residual soda water flows into the drinking water tank 11 after passing through the delivery waterway 12, the drinking water valve 14 and the circulation water valve 15; if the residual soda water can enter the drinking water tank 11 without passing through the drinking water valve 14 in the backflow process, the circulating water valve 15 and the circulating pump 16 are only required to be simultaneously opened. The opening and closing of the drinking water valve 14 in the soda water reflux mode is not limited in this embodiment, and can be adjusted according to actual production conditions.
