[0002] With the changes in the market, cold drinks are becoming increasingly popular in the market, and cold coffee is no exception and is increasingly favored by users. Traditional coffee machines can only make hot coffee and are increasingly unable to meet the needs of users. If a traditional coffee machine wants to make cold coffee, it must quickly cool down the heating pot, which will generate a lot of waste water, and the waiting time during the production process is long. Or add ice cubes to the coffee cup in advance, but there are factual defects such as dilution of coffee concentration and deterioration of taste.

[0003] For example, the Chinese invention patent with the publication number CN118076271A for a coffee machine for generating hot and cold infusion liquids discloses a coffee machine including a hydraulic circuit. The hydraulic circuit includes an infuser, a water tank, a steam generator, a steam distributor, a hot water generator, a supply pump for supplying water to the steam generator and the hot water generator... In this first switching configuration, the supply pump, the hot water generator, and the infuser are connected in series. In this second switching configuration, the supply pump and the infuser are connected in series through the bypass pipeline of the hot water generator. In this third switching configuration, the supply pump and the steam generator are connected in series. Although it can switch different waterways to meet different needs of users, its structure is complex and it cannot independently control the waterway. Utility Model Content

[0048] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", each of which may refer to one or more of the same or different embodiments according to the present application.

[0049] An embodiment of the present application provides a waterway system for a coffee machine, such as Figures 1 - 4 shown, the waterway system includes a water tank 1, a first water pump 2, a coffee heating pot assembly 3, a second water pump 4, a brewing assembly 5, and a steam heating pot assembly 7.

[0050] The water tank 1 stores the liquid (such as clean water) used for brewing coffee. Wherein, the water tank 1 is provided with a water inlet for the user to supplement the liquid in the water tank 1 through the water inlet.

[0051] The water inlet of the first water pump 2 is communicated with the water tank 1, and the water inlet of the coffee heating pot assembly 3 is communicated with the water outlet of the first water pump 2, for heating the liquid conveyed by the first water pump 2 to form hot liquid.

[0052] The second water pump 4 is arranged in parallel with the first water pump 2, and the water inlet of the second water pump 4 is communicated with the water tank 1 for conveying cold liquid. Among them, the conveyed cold liquid can be directly used for brewing coffee.

[0053] By providing the first water pump 2 and the second water pump 4, the present application realizes the independent conveyance of hot liquid and cold liquid, improving the flexibility and efficiency of use. Among them, the first water pump 2 provides a water source for making hot coffee and steam, and the second water pump 4 provides a water source for making cold coffee.

[0054] The water inlets of the brewing assembly 5 are respectively communicated with the water outlet of the coffee heating pot assembly 3 and the water outlet of the second water pump 4, and the water outlet of the brewing assembly 5 is communicated with a coffee spout 6.

[0055] When hot liquid enters the brewing component 5, hot coffee can be made; when cold liquid enters the brewing component 5, cold coffee can be made, so as to meet different needs of users. Moreover, by directly using cold liquid to make cold coffee, compared with the method of putting ice cubes into hot coffee, the method of the present application enables cold coffee to solve the problem that the ice cubes dilute the coffee concentration and affect the taste.

[0056] The water inlet of the steam heating pot component 7 is communicated with the water outlet of the coffee heating pot component 3, and its water outlet is communicated with the steam nozzle 8. Wherein, after the hot liquid enters the steam heating pot component 7, it is made into steam, and the steam is discharged through the steam nozzle 8 for the user to use. The setting of the steam heating pot component 7 allows the user to use steam to make milk foam or other operations that require steam, increasing the versatility of the coffee machine.

[0057] In this embodiment, the water inlet of the first water pump 2 is communicated with the water tank 1. When started, the first water pump 2 transports the liquid in the water tank 1 to the coffee heating pot component 3. The coffee heating pot component 3 receives the liquid transported by the first water pump 2 and heats it to form hot liquid.

[0058] The second water pump 4 is arranged in parallel with the first water pump 2, and its water inlet is also communicated with the water tank 1, and is used to transport cold liquid, so as to allow the second water pump 4 to directly supply cold liquid to the brewing component 5 for brewing cold coffee.

[0059] The water inlet of the brewing component 5 is simultaneously connected to the water outlet of the coffee heating pot component 3 and the water outlet of the second water pump 4, and hot liquid or cold liquid can be selected for brewing according to the user's needs. When the user selects hot coffee, the hot liquid enters the brewing component 5 and makes hot coffee; when the user selects cold coffee, the cold liquid enters the brewing component 5 and makes cold coffee. The water outlet of the brewing component 5 is communicated with the coffee nozzle 6 to complete the brewing of coffee.

[0060] The water inlet of the steam heating pot component 7 is communicated with the water outlet of the coffee heating pot component 3, receives the liquid and makes it into steam. The steam is discharged through the steam nozzle 8 for the user to use.

[0061] Among them, as Figure 2 shown, the working process of making hot coffee:

[0062] Start the first water pump 2, and the first water pump 2 transports the liquid in the water tank 1 to the coffee heating pot component 3. The coffee heating pot component 3 heats the liquid transported by the first water pump 2 to form hot liquid. The hot liquid flows out from the water outlet of the coffee heating pot component 3 and enters the water inlet of the brewing component 5. The brewing component 5 receives the hot liquid and brews coffee in the brewing component 5. The brewed hot coffee flows into the coffee nozzle 6 through the water outlet of the brewing component 5 for the user to enjoy.

[0063] Among them, as Figure 3 shown, the working process of making cold coffee:

[0064] Start the second water pump 4, and the second water pump 4 conveys the cold liquid in the water tank 1 to the water inlet of the brewing component 5. The brewing component 5 receives the cold liquid and conducts coffee brewing inside the brewing component 5. The brewed cold coffee flows into the coffee spout 6 through the water outlet of the brewing component 5 for the user to enjoy. Since cold liquid is directly used for brewing, the problem of ice cubes diluting the coffee concentration is avoided, ensuring the taste of the cold coffee.

[0065] Among them, as Figure 4 shown, the working process of making steam:

[0066] Start the first water pump 2, and the first water pump 2 conveys the liquid in the water tank 1 to the coffee heating pot component 3. The coffee heating pot component 3 heats the liquid conveyed by the first water pump 2 to form hot liquid. The hot liquid flows out from the water outlet of the coffee heating pot component 3 and enters the water inlet of the steam heating pot component 7. The steam heating pot component 7 makes steam from the received hot liquid. The made steam is discharged through the steam outlet of the steam heating pot component 7 and is supplied to the user through the steam nozzle 8. The user can use the discharged steam for milk frothing or other operations that require steam.

[0067] Through the above structure, the present application meets the user's needs for making hot coffee, cold coffee or steam, realizes the versatility of the coffee machine, and improves the efficiency of the coffee machine and the user experience.

[0068] As an alternative embodiment, as Figure 1 shown, the water circuit system further includes a flow meter 9 and a first three-way pipe 10.

The water inlet of the first three-way pipe 10 is communicated with the water outlet of the flow meter 9, its first water outlet is communicated with the water inlet of the first water pump 2, and its second water outlet is communicated with the water inlet of the second water pump 4.

[0070] By adding the flow meter 9 and the first three-way pipe 10 in the present application, the flow rate flowing out from the water tank 1 can be more precisely controlled, ensuring the brewing effect of coffee, thereby improving the taste and quality of coffee.

The water inlet of the protection valve assembly 11 is communicated with the water outlet of the first water pump 2, its first water outlet is communicated with the water return port of the water tank 1, and its second water outlet is communicated with the water inlet of the coffee heating pot component 3.

[0072] The introduction of the protection valve assembly 11 in this application provides additional safety protection for the water circuit system. It can prevent excessive liquid or overpressure, ensure the coffee machine operates under safe conditions, and extend the service life of the equipment.

[0073] As an alternative embodiment, as Figure 1 shown, the water circuit system further includes a second three-way pipe 12 and a first three-way solenoid valve 13.

[0074] The water inlet of the second three-way pipe 12 is communicated with the water outlet of the coffee heating pot assembly 3. The water inlet of the first three-way solenoid valve 13 is communicated with the first water outlet of the second three-way pipe 12, and its first water outlet is communicated with the water inlet of the brewing assembly 5.

[0075] Wherein, the channel between the water inlet and the first water outlet of the first three-way solenoid valve 13 is in a normally closed state, and the channel between the first water outlet and the second water outlet of the first three-way solenoid valve 13 is in a normally open state.

[0076] In this application, through the combination of the second three-way pipe 12 and the first three-way solenoid valve 13, hot liquid is transported to the brewing assembly 5 for brewing to form hot coffee, meeting the user's needs.

[0077] As an alternative embodiment, as Figure 1 shown, the water circuit system further includes a third three-way pipe 14. The first water inlet of the third three-way pipe 14 is communicated with the first water outlet of the first three-way solenoid valve 13, its second water inlet is communicated with the water outlet of the second water pump 4, and its water outlet is communicated with the water inlet of the brewing assembly 5.

[0078] In this application, by setting the third three-way pipe 14, cold liquid is transported to the brewing assembly 5 for brewing to form cold coffee, meeting the user's needs and improving the flexibility of using the coffee machine.

[0079] As an alternative embodiment, as Figure 1 shown, the water circuit system further includes a second three-way solenoid valve 15. The water inlet of the second three-way solenoid valve 15 is communicated with the second water outlet of the second three-way pipe 12, and its first water outlet is communicated with the water inlet of the steam heating pot assembly 7.

[0080] Wherein, the channel between the water inlet and the first water outlet of the second three-way solenoid valve 15 is in a normally closed state, and the channel between the first water outlet and the second water outlet of the second three-way solenoid valve 15 is in a normally open state.

[0081] In this application, by setting the second three-way solenoid valve 15, liquid is transported to the steam heating pot assembly 7 to form steam, meeting different user needs and enabling the coffee machine to adapt to different usage scenarios.

[0082] As an optional embodiment, Figure 1 As shown, the water system also includes a fourth three-way pipe 16, the first water inlet of the fourth three-way pipe 16 is connected to the second water outlet of the first three-way solenoid valve 13, the second water inlet is connected to the second water outlet of the second three-way solenoid valve 15, and the water outlet is connected to the water inlet of the waste water box 17 for pressure relief.

[0083] The present application provides an effective pressure relief mechanism for the water system by setting the fourth three-way pipe 16, which helps to maintain a stable pressure during the operation of the coffee machine and prevent equipment damage or safety accidents caused by excessive pressure.

[0084] In summary, when making hot coffee, the hot coffee water circuit includes the water tank 1, the first water pump 2, the coffee heating pot assembly 3, the first three-way solenoid valve 13, the brewing assembly 5, and the coffee spout 6. When making steam, the steam water circuit includes the water tank 1, the first water pump 2, the coffee heating pot assembly 3, the second three-way solenoid valve 15, the steam heating pot assembly 7, and the steam spout 8. When making cold coffee, the cold coffee water circuit includes the water tank 1, the second water pump 4, the brewing assembly 5, and the coffee spout 6.

[0085] The present application also includes a controller, which is respectively connected to the first water pump 2, the second water pump 4, the flow meter 9, the first three-way solenoid valve 13, the second three-way solenoid valve 15, the coffee heating pot assembly 3, the brewing assembly 5 and the steam heating pot assembly 7. The controller controls the power on and off of each component according to user needs to realize the switching of different water paths.

[0086] When making hot coffee, the controller controls the first water pump 2 to be energized to supply water. The water supplied by the first water pump 2 is first heated by the coffee heating pot assembly 3. At the same time, the first three-way solenoid valve 13 is energized, the channel between the water inlet and the first water outlet of the first three-way solenoid valve 13 is opened, and the channel between the water inlet and the second water outlet of the first three-way solenoid valve 13 is closed. The channel between the first water outlet and the second water outlet of the first three-way solenoid valve 13 is closed.

[0087] At this time, the second water pump 4 is in a power-off state. Since the second water pump 4 has a one-way valve, the passage between the water outlet of the second water pump 4 and the first water outlet of the first three-way solenoid valve 13 is also in a closed state under the action of the one-way valve. Therefore, at this time, water can only pass through the coffee heating pot component 3. The controller controls the coffee heating pot component 3 to heat the liquid to hot water at about 98 degrees, and the hot water enters the brewing component 5 to make hot coffee.

[0088] After the hot coffee is made, the controller controls the first water pump 2 and the first three-way solenoid valve 13 to cut off power simultaneously, causing the first water pump 2 to stop supplying water. At the same time, the channel between the water inlet and the first water outlet of the first three-way solenoid valve 13 is closed, and the channel between the first water outlet and the second water outlet is opened. The residual pressure in the coffee brewing chamber of the brewing assembly 5 will be discharged into the waste water box 17 through the third three-way pipe 14, the channel between the first water outlet and the second water outlet of the first three-way solenoid valve 13, and the fourth three-way pipe 16.

[0089] When making cold coffee, the controller controls the second water pump 4 to be powered on for water supply. The water outlet of the second water pump 4 is directly connected to the brewing assembly 5 through the water outlet of the third three-way pipe 14.

[0090] At the same time, the first three-way solenoid valve 13 is powered on. The channel between the water inlet and its first water outlet of the first three-way solenoid valve 13 is opened, the channel between the water inlet and its second water outlet of the first three-way solenoid valve 13 is closed, and the channel between the first water outlet and the second water outlet of the first three-way solenoid valve 13 is closed.

[0091] Since the water inlet of the first three-way solenoid valve 13 is connected to the water outlet of the first water pump 2, and the first water pump 2 is equipped with a check valve, under the action of the check valve, the water inlet of the first three-way solenoid valve 13 is also in a closed state. Therefore, the cold water supplied by the second water pump 4 when it is powered on directly enters the brewing assembly 5 for making cold coffee.

[0092] After the cold coffee is made, the controller controls the second water pump 4 to cut off power and, at the same time, the first three-way solenoid valve 13 to cut off power. At this time, the second water pump 4 stops supplying water. The channel between the water inlet and the first water outlet of the first three-way solenoid valve 13 is closed, and the channel between the first water outlet and the second water outlet of the first three-way solenoid valve 13 is opened. The residual pressure in the coffee brewing chamber of the brewing assembly 5 will be discharged into the waste water box 17 through the third three-way pipe 14, the channel between the first water outlet and the second water outlet of the first three-way solenoid valve 13, and the fourth three-way pipe 16.

[0093] When making steam, the controller controls the first water pump 2 to be powered on for intermittent water supply. The water supplied by the first water pump 2 first passes through the coffee heating pot assembly 3. At this time, the first three-way solenoid valve 13 is in a power-off state. The channel between the water inlet and the first water outlet of the first three-way solenoid valve 13 is closed, and the channel between the water inlet and the second water outlet of the first three-way solenoid valve 13 is closed.

[0094] The second three-way solenoid valve 15 is in a powered-on state. The channel between the water inlet and the first water outlet of the second three-way solenoid valve 15 is opened, the channel between the water inlet and the first water outlet of the second three-way solenoid valve 15 is closed, and the channel between the first water outlet and the second water outlet of the second three-way solenoid valve 15 is closed.

[0095] At this time, the water passing through the coffee heating pot assembly 3 can only enter the steam heating pot assembly 7. The controller controls the steam heating pot assembly 7 to heat the water to 110 - 130 degrees. After the water is heated into steam, it is ejected from the steam nozzle 8.

[0096] Among them, the coffee heating pot assembly 3 can be powered on to heat the liquid once and then send it to the steam heating pot assembly 7. The steam heating pot assembly 7 performs a second heating to reach the required steam temperature. Or, the coffee heating pot assembly 3 is powered off, and the steam heating pot assembly 7 directly heats the liquid.

[0097] When the steam production is completed, the controller controls the first water pump 2 and the second three-way solenoid valve 15 to be powered off. At this time, the first water pump 2 stops supplying water, the channel between the water inlet and the first water outlet of the second three-way solenoid valve 15 is closed, and the channel between the first water outlet and the second water outlet of the second three-way solenoid valve 15 is opened. The residual pressure and residual water in the steam heating pot assembly 7 will be discharged into the waste water box 17 through the channel between the first water outlet and the second water outlet of the second three-way solenoid valve 15.

[0098] The embodiment of the present application also provides a coffee machine, including the waterway system as described above. The present application integrates the above waterway system into the coffee machine, enabling the coffee machine to have more advanced functions and higher operation flexibility, not only improving the user experience, but also possibly attracting a wider consumer group, thereby increasing the market competitiveness of the product.

[0099] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
