[0001] This utility model relates to the field of coffee machine technology, specifically a coffee machine water circuit system. Background Technology
[0002] With the diversification of modern lifestyles and the ever-increasing demand for coffee quality, coffee machines have become indispensable appliances in both home and business environments. However, current coffee machines on the market still have certain limitations in terms of functionality and user experience. On the one hand, most coffee machines are limited to hot brewing, while making cold brew coffee usually requires additional equipment or a long waiting time. This limitation makes it difficult for users to quickly enjoy high-quality cold brew coffee, failing to meet the modern consumer's demand for convenience.
[0003] On the other hand, when using coffee machines daily, consumers often need to rely on other equipment to provide hot or cold water or room temperature water in order to adjust the coffee concentration or meet personalized drinking needs. This not only increases the complexity and inconvenience of the usage process, but also requires additional equipment support, resulting in a larger overall space occupation, especially in space-constrained environments such as kitchens or offices, where this problem is more prominent.
[0004] Therefore, it is necessary to develop a coffee machine water system that can simultaneously support hot and cold brew functions and provide hot and cold water as well as room temperature water to improve ease of use and space utilization. Utility Model Content
[0005] To address the problem mentioned above that existing coffee machines can only perform hot extraction and lack the functions of preparing cold brew coffee and adjusting water temperature, the technical solution adopted by this utility model is as follows:
[0006] A coffee machine water system includes a water inlet, an inlet pipe connected to the water inlet, and an outlet pipe connected to the inlet pipe. The outlet pipe is provided with a valve body assembly connected to the inlet pipe, a heating assembly connected to the valve body assembly, a switching assembly connected to both the valve body assembly and the heating assembly, and an outlet connected to the switching assembly. The inlet pipe delivers cold water or room temperature water to the outlet through the valve body assembly. The heating assembly provides hot water to the outlet. The switching assembly controls the outlet to output coffee or water.
[0007] Furthermore, in the coffee machine water system described in the solution, the inlet pipe is provided with a first pipe for conveying room temperature water, a second pipe for conveying cold water, and a first reversing valve located downstream of the first and second pipes and connected to the outlet pipe, and a refrigeration component is connected upstream of the second pipe.
[0008] Furthermore, in the coffee machine water system described in the solution, the liquid inlet pipe further includes a water storage chamber located upstream of the first pipe and the second pipe, and a first disinfection component located between the refrigeration component and the first reversing valve. The water storage chamber is equipped with a water level control component and a second disinfection component.
[0009] Furthermore, in the coffee machine water circuit system described in the solution, the valve body assembly further includes a second reversing valve connected to the first reversing valve, a third pipe connecting the second reversing valve and the switching assembly, and a fourth pipe connecting the second reversing valve and the heating assembly. The third pipe is equipped with a water pumping assembly, and the fourth pipe is equipped with a flow meter assembly and a high-pressure pump assembly.
[0010] Furthermore, in the coffee machine water system described in the solution, the liquid outlet pipeline is provided with a fifth pipe connected to the switching component and used to deliver water to the liquid outlet, and a sixth pipe connected to the switching component and used to deliver coffee to the liquid outlet.
[0011] Furthermore, in the coffee machine water circuit system described in the solution, the switching component is provided with a high-pressure reversing valve connected to the heating component, the fifth pipe and the sixth pipe are both connected to the high-pressure reversing valve and the liquid outlet, the fifth pipe is provided with a third reversing valve connected to the third pipe, and the sixth pipe is connected to the brewing component.
[0012] Furthermore, the coffee machine water system described in the solution also includes a filter assembly located between the water inlet and the liquid inlet pipe. The filter assembly is provided with a first filter element, a second filter element connected to the first filter element, and a booster pump valve assembly that drives water into the water inlet. The booster pump valve assembly is located between the first filter element and the second filter element.
[0013] Furthermore, in the coffee machine water system described in the solution, the filter component is also provided with a waste outlet, the fourth pipe is also provided with a drain valve connecting the heating component and the waste outlet, and the second filter element is connected to the waste outlet.
[0014] Furthermore, the coffee machine water system described in the solution also includes a cold water outlet connected to the valve body assembly, and the third pipe is also provided with a three-way assembly that is connected to the cold water outlet and the switching assembly respectively, and the cold water outlet is provided with a plug.
[0015] Furthermore, in the coffee machine water system described in the solution, the refrigeration components are cooled by a compressor or an electronic ice chamber.
[0016] The beneficial effects of this utility model are as follows:
[0017] This invention, by incorporating an inlet pipe capable of supplying cold or room temperature water, a heating element capable of supplying hot water, and a switching element capable of controlling the output of coffee or water from the outlet in the coffee machine's water circuit system, enables the coffee machine to directly output cold, hot, and room temperature water, thus meeting users' needs for water at different temperatures. Furthermore, the cooperation between the valve assembly and the switching element allows coffee to be output from the outlet. This means the switching element can not only work with the heating element to produce hot brew coffee, but also directly utilize the cold water supplied by the inlet pipe to make cold brew coffee. This design not only meets modern consumers' demands for convenience in coffee machines, but also reduces the need for other equipment by integrating multiple functions, thereby effectively reducing space occupancy.
[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0022] Figure 4 This is a schematic diagram of the liquid circuit of a coffee machine water circuit system according to the present invention. Detailed Implementation
[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] like Figure 1-4 The coffee machine water system shown includes an inlet 1, an inlet pipe 2 connected to the inlet 1, and an outlet pipe 3 connected to the inlet pipe 2. The outlet pipe 3 is provided with a valve body assembly 31 connected to the inlet pipe 2, a heating assembly 32 connected to the valve body assembly 31, a switching assembly 33 connected to the valve body assembly 31 and the heating assembly 32 respectively, and an outlet 34 connected to the switching assembly 33. The inlet pipe 2 delivers cold water or room temperature water to the outlet 34 through the valve body assembly 31. The heating assembly 32 is used to provide hot water to the outlet 34. The switching assembly 33 is used to control the outlet 34 to output coffee or water.
[0025] This invention, by incorporating an inlet pipe 2 capable of providing cold or room temperature water, a heating element 32 capable of providing hot water, and a switching element 33 capable of controlling the output of coffee or water from the outlet 34 into the coffee machine's water system, enables the coffee machine to directly output cold, hot, and room temperature water, thus meeting users' needs for water at different temperatures. Furthermore, the cooperation between the valve assembly 31 and the switching element 33 allows coffee to be output from the outlet 34. This means the switching element 33 can not only work with the heating element 32 to produce hot brew coffee, but also directly utilize the cold water provided by the inlet pipe 2 to produce cold brew coffee. This design not only meets modern consumers' demands for convenience in coffee machines, but also reduces the need for other equipment by integrating multiple functions, thus effectively reducing space occupancy.
[0026] This invention integrates hot and cold water supply by incorporating a cold water inlet pipe 2 and a heating element 32 into the coffee machine's water system. This allows the coffee machine to not only have the traditional hot brew function but also a cold brew function. This design solves the problem that most coffee machines on the market are limited to hot brew, allowing users to enjoy cold brew coffee without relying on additional equipment or waiting for a long cooling time. Furthermore, the inlet pipe 2 delivers cold or room temperature water to the outlet 34 via a valve assembly 31, while the heating element 32 provides hot water to the outlet 34. In conjunction with the switching component 33, the coffee machine can... The ability to switch between cold water, hot water, room temperature water, hot brew coffee, and cold brew coffee meets users' needs for beverages at different temperatures. Furthermore, the addition of the switching component 33 allows the dispensing spout 34 to flexibly switch between water and coffee output, increasing the coffee machine's versatility. Users can directly use water of different temperatures provided by the machine to adjust the coffee concentration to match their personal taste preferences, or obtain drinking water at the desired temperature for other purposes when not making coffee. This effectively reduces reliance on additional equipment and lowers the number of devices and space required in the kitchen or office. More specifically, when users need to use… When supplying cold water, the cold water delivered by the inlet pipe 2 passes sequentially through the valve body assembly 31 and the switching assembly 33. The switching assembly 33 then switches the water supply pipe to the outlet 34, thus outputting cold water. When the user needs hot water, the room temperature water delivered by the inlet pipe 2 passes sequentially through the valve body assembly 31, the heating assembly 32 (in heating mode), and the switching assembly 33. The switching assembly 33 then switches the water supply pipe to the outlet 34, thus outputting hot water. When the user needs room temperature water, the room temperature water delivered by the inlet pipe 2 passes sequentially through the valve body assembly 31, the heating assembly 32, and the switching assembly 33. The switching assembly 33 then switches the water supply pipe to the outlet 34, thus outputting hot water. The inlet 34 allows for the output of room temperature water, during which the heating component 32 is not activated. When the user wants to drink hot brew coffee, the room temperature water supplied by the inlet pipe 2 passes sequentially through the valve body assembly 31, the heating component 32 (which is in a heated state), and the switching component 33. The switching component 33 then switches the coffee supply pipe to the outlet 34, thus enabling the output of hot brew coffee. When the user wants to drink cold brew coffee, the cold water supplied by the inlet pipe 2 passes sequentially through the valve body assembly 31, the heating component 32 (which is in a closed state), and the switching component 33. The switching component 33 then switches the coffee supply pipe to the outlet 34, thus enabling the output of cold brew coffee.
[0027] Furthermore, such as Figure 1-4The coffee machine water system shown includes an inlet pipe 2 with a first pipe 21 for conveying room temperature water, a second pipe 22 for conveying cold water, and a first reversing valve 23 located downstream of the first pipe 21 and the second pipe 22 and connected to the outlet pipe 3. The upstream end of the second pipe 22 is connected to a refrigeration component 221.
[0028] This invention, by setting a first pipe 21 for conveying room temperature water and a second pipe 22 for conveying cold water in the liquid inlet pipe 2, and cooperating with a first reversing valve 23 located downstream of the first pipe 21 and the second pipe 22 and connected to the liquid outlet pipe 3, can switch the first reversing valve 23 to select water of different temperatures according to needs, thus meeting the user's needs for cold water and room temperature water; furthermore, by setting a refrigeration component 221 upstream of the second pipe 22, the water can be directly processed by the refrigeration component 221 to produce the cold water required for cold brewing coffee in the coffee machine when it flows through the second pipe 22, without the need for additional waiting or the use of other equipment for cooling, which greatly improves the efficiency and convenience of making cold brew coffee.
[0029] Furthermore, such as Figure 1-4 The coffee machine water system shown includes an inlet pipe 2 that further includes a water storage chamber 24 located upstream of the first pipe 21 and the second pipe 22, and a first disinfection component 25 located between the refrigeration component 221 and the first reversing valve 23. The water storage chamber 24 is provided with a water level control component 241 and a second disinfection component 242.
[0030] This invention, by setting a water storage chamber 24, not only provides users with a stable and reliable water supply source but also reduces the need for frequent water filling, improving ease of use. Furthermore, by setting a water level control component 241 in the water storage chamber 24, which in this embodiment includes an electronic float and a mechanical float, the electronic float automatically maintains an appropriate water level to ensure normal system operation, while the mechanical float serves as a redundancy design to prevent water level loss of control in extreme situations, enhancing the system's reliability and safety. Furthermore, a second disinfection component 242 is also provided in the water storage chamber 24. In this embodiment, the second disinfection component 242 uses a UV lamp, which can effectively kill bacteria and viruses that may exist in the water, ensuring the safety of the user's drinking water. Furthermore, this invention sets a first disinfection component 25 between the refrigeration component 221 and the first reversing valve 23. In this embodiment, the first disinfection component 25 uses a flow-through UV lamp. This design ensures that the water after refrigeration is subjected to ultraviolet disinfection again, eliminating the risk of microbial contamination that may occur during the refrigeration process, providing users with a cleaner and healthier source of cold drinking water.
[0031] Furthermore, such as Figure 1-4The coffee machine water circuit system shown includes a valve body assembly 31 that further includes a second reversing valve 311 connected to the first reversing valve 23, a third pipe 312 connecting the second reversing valve 311 and the switching assembly 33, and a fourth pipe 313 connecting the second reversing valve 311 and the heating assembly 32. The third pipe 312 is provided with a water pumping assembly 3121, and the fourth pipe 313 is provided with a flow meter assembly 3131 and a high-pressure pump assembly 3132.
[0032] This invention, by setting a second reversing valve 311 in the valve body assembly 31, ensures that water flowing from the inlet pipe 2 to the valve body assembly 31 must pass through both the first reversing valve 23 and the second reversing valve 311, effectively preventing cross-contamination between different water lines and preventing the coffee machine from being affected if one of the reversing valves malfunctions. Furthermore, by setting a water pump assembly 3121 on the third pipe 312 (in this embodiment, the water pump assembly 3121 is a water pump), this design not only allows for the extraction of an appropriate amount of water for use, but also enables the water pump to operate smoothly. When not in use, it can also stop the water flow to prevent further outflow, and can also enter a pressurized state to protect the water pump from unnecessary damage. Furthermore, by setting a flow meter assembly 3131 and a high-pressure pump assembly 3132 in the fourth pipe 313, precise control and efficient transmission of water flow are ensured. The flow meter assembly 3131 can monitor and adjust the amount of water passing through the heating assembly 32, while the high-pressure pump assembly 3132 provides sufficient pressure so that the water can quickly reach the heating assembly 32 and be made into hot coffee or hot water to meet the user's immediate needs.
[0033] Furthermore, such as Figure 1-4 The coffee machine water system shown includes a fifth pipe 332 connected to a switching component 33 for delivering water to the outlet 34, and a sixth pipe 333 connected to the switching component 33 for delivering coffee to the outlet 34.
[0034] This invention, by setting up a fifth pipe 332 and a sixth pipe 333, enables water to be transported through the fifth pipe 332 and coffee to be transported through the sixth pipe 333. This ensures the independence of the two liquid paths, avoids cross-contamination, and improves water quality safety and beverage purity.
[0035] Furthermore, such as Figure 1-4The coffee machine water circuit system shown includes a switching component 33 having a high-pressure reversing valve 331 connected to the heating component 32. The fifth pipe 332 and the sixth pipe 333 are both connected to the high-pressure reversing valve 331 and the liquid outlet 34. The fifth pipe 332 has a third reversing valve 3321 connected to the third pipe 312. The sixth pipe 333 is connected to the brewing component 3331.
[0036] This invention incorporates a high-pressure reversing valve 331 connected to the heating component 32 within the switching assembly 33. Both the fifth pipe 332 and the sixth pipe 333 are connected to the high-pressure reversing valve 331 and the outlet 34, enabling water to be transported via the fifth pipe 332 and coffee via the sixth pipe 333. This ensures the independence of the two liquid paths, preventing cross-contamination and improving water safety and beverage purity. Furthermore, the fifth pipe 332 is equipped with a third reversing valve 3321 connected to the third pipe 312, allowing cold water to directly enter the third pipe 312 through the second reversing valve 311, then enter the fifth pipe 332 from the third pipe 312, and finally flow out from the outlet 34. This reduces the flow path of the cold water and effectively improves water output efficiency. Moreover, by incorporating a brewing assembly 3331 in the sixth pipe 333, the brewing assembly 3331, in conjunction with the high-pressure reversing valve 331, enables a highly efficient coffee brewing process, ensuring not only the taste and quality of the coffee but also significantly improving production efficiency.
[0037] Furthermore, such as Figure 1-4 The coffee machine water system shown includes a filter assembly 4 located between the water inlet 1 and the liquid inlet pipe 2. The filter assembly 4 is provided with a first filter element 41, a second filter element 42 connected to the first filter element 41, and a booster pump valve assembly 43 that drives water to enter the water inlet 1. The booster pump valve assembly 43 is located between the first filter element 41 and the second filter element 42.
[0038] This invention incorporates a filter assembly 4 between the water inlet 1 and the liquid inlet pipe 2. This effectively solves the problem of impurities in the water source, ensuring the purity of the water entering the coffee machine. Furthermore, the filter assembly 4 includes a first filter element 41, a second filter element 42 located downstream of the first filter element 41, and a booster pump valve assembly 43 located between the two and used to drive water into the water inlet 1. The booster pump valve assembly 43 ensures stable water supply even under low water pressure conditions. In this embodiment, the first filter element 41 is a composite filter element, and the second filter element 42 is an RO (reverse osmosis) filter element. This not only effectively removes particulate matter, residual chlorine, and other harmful substances from the water but also provides deeper purification, ensuring optimal water quality for coffee brewing.
[0039] Furthermore, such as Figure 1-4The coffee machine water system shown includes a filter assembly 4 with a waste outlet 44, a fourth pipe 313 with a drain valve 3133 connecting the heating assembly 32 and the waste outlet 44, and the second filter element 42 connected to the waste outlet 44.
[0040] This invention provides a waste outlet 44 in the filter assembly 4, and the second filter element 42 is connected to the waste outlet 44. This arrangement allows the filter assembly 4 to promptly discharge waste generated during the filtration process, maintaining the cleanliness and hygiene of the system. Furthermore, by providing a vent valve 3133 on the fourth pipe 313 that connects the heating assembly 32 and the waste outlet 44, the vent valve 3133 can not only remove the gas generated during the heating process, but also completely drain the water in the heating assembly 32 during maintenance or when it is not in use for a long time. This avoids the decrease in heating efficiency and potential safety hazards caused by scale accumulation, thereby enhancing the reliability and safety of the coffee machine.
[0041] Furthermore, such as Figure 1-4 The coffee machine water system shown includes a cold water outlet 5 connected to the valve body assembly 31. The third pipe 312 is also provided with a three-way assembly 3122 connected to the cold water outlet 5 and the switching assembly 33 respectively. The cold water outlet 5 is provided with a plug.
[0042] This invention provides a stable cold water supply interface for external devices by setting a cold water outlet 5. Whether it is other appliances in a home kitchen or coffee-making auxiliary equipment in a commercial environment, the required cold water can be obtained directly from the cold water outlet 5 without the need for additional cooling devices. This not only meets the needs of users in different scenarios but also improves the convenience and efficiency of use. Furthermore, the third pipe 312 is equipped with a three-way component 3122 that connects to the cold water outlet 5 and the switching component 33 respectively. This setting allows for flexible supply and use of cold water in the third pipe 3. Furthermore, since there is no control valve for the cold water outlet 5 in this invention, a plug is set in the cold water outlet 5 to prevent cold water from flowing out when the cold water outlet 5 is not in use. Furthermore, when the cold water outlet 5 is not in use, the plug can also effectively seal the outlet to prevent dust and other impurities from entering the internal pipes, keeping the system clean and hygienic. This setting not only protects the internal components of the coffee machine from contamination but also simplifies the user's daily maintenance work.
[0043] Furthermore, such as Figure 1-4 The coffee machine water system shown is wherein the refrigeration component 221 is cooled by a compressor or an electronic ice chamber.
[0044] The refrigeration component 221 of this invention can achieve a high-efficiency refrigeration effect through a compressor. The application of the compressor can quickly reduce the water temperature and provide readily available low-temperature cold water, which is particularly suitable for making beverages such as cold brew coffee that require high temperature. Furthermore, the refrigeration component 221 can also use an electronic ice chamber for refrigeration. The electronic ice chamber has the characteristics of compact structure and low energy consumption, and is suitable for situations that require maintaining a low-temperature environment for a long time.
[0045] like Figure 1-4 As shown, the embodiments of this utility model are as follows:
[0046] Example 1:
[0047] This embodiment provides a coffee machine water system that integrates cold brew, hot brew, hot water output, cold water output, and room temperature water output functions. The system receives water through inlet 1, and supplies cold or room temperature water to outlet 3 via inlet pipe 2 connected to inlet 1. The water flow is then guided to different processing paths according to the user's selection, ultimately outputting the desired coffee or water from outlet 34.
[0048] When a user wants to make a hot brew coffee, room temperature water first enters the coffee machine's internal inlet pipe 2 through inlet 1. As the water flows forward, it reaches valve assembly 31, where the flow is controlled and guided to heating assembly 32. Heating assembly 32 then activates, rapidly heating the water to a suitable temperature for brewing coffee. The heated water continues its journey, and upon passing switching assembly 33, since the user has selected the coffee brewing mode, switching assembly 33 switches the coffee delivery pipe to outlet 34, ensuring hot water flows into the area where the coffee grounds are located for extraction, thus resulting in hot brew coffee flowing out of outlet 34.
[0049] When a user wants to drink cold brew coffee, water enters from the inlet 1 and flows through the inlet pipe 2 after being cooled. It then flows to the valve assembly 31. During the cold brew process, the heating assembly 32 is in the off state and does not perform heating operation. This allows the cold water to pass directly through the heating assembly 32 and reach the switching assembly 33. The switching assembly 33 switches the coffee delivery pipe to the outlet 34, ensuring that the cold water flows into the area where the coffee powder is located for extraction. This allows the cold brew coffee to flow out of the outlet 34.
[0050] In addition, the coffee machine's water system can also provide drinking water at different temperatures.
[0051] When the user needs to use cold water, the cold water in the inlet pipe 2 does not need to pass through the heating component 32, but directly through the valve body component 31 and the switching component 33. The switching component 33 switches the water delivery pipe to the outlet 34, thereby realizing the output of cold water.
[0052] When a user needs hot water, the room temperature water in the inlet pipe 2 will pass through the valve body assembly 31, the heating assembly 32 which is in a heating state, and the switching assembly 33 in sequence. The switching assembly 33 will then switch the water supply pipe to the outlet 34, thereby realizing the output of hot water.
[0053] When the user needs to use room temperature water, the room temperature water in the inlet pipe 2 will pass through the valve body assembly 31, the heating assembly 32 (without heating function turned on), and the switching assembly 33 in sequence. The switching assembly 33 will then switch the water delivery pipe to the outlet 34, thereby achieving the output of room temperature water.
[0054] Example 2:
[0055] This embodiment includes the features of Embodiment 1, but differs from Embodiment 1 in that it sets up a first pipe 21 for conveying room temperature water and a second pipe 22 for conveying cold water in the inlet pipe 2. It also uses a first reversing valve 23 located downstream of the first and second pipes 21 and connected to the outlet pipe 3. This allows for switching the first reversing valve 23 to select water of different temperatures, meeting the user's needs for both cold and room temperature water. Furthermore, by setting up a cooling component 221 upstream of the second pipe 22, water flowing through the second pipe 22 can directly pass through the cooling component 221 to produce the cold water needed for cold brewing in the coffee machine, eliminating the need for additional waiting or cooling with other equipment, greatly improving the efficiency and convenience of making cold brew coffee.
[0056] Example 3:
[0057] This embodiment incorporates features of Embodiment 2, but differs in that it includes a water storage chamber 24. This design not only provides users with a stable and reliable water supply but also reduces the need for frequent water replenishment, improving ease of use. Furthermore, a water level control component 241 is incorporated into the water storage chamber 24. In this embodiment, the water level control component 241 includes an electronic float and a mechanical float. The electronic float automatically maintains an appropriate water level to ensure normal system operation, while the mechanical float serves as a redundancy design to prevent water level loss in extreme situations, enhancing system reliability. In addition, a second disinfection component 242 is provided in the water storage chamber 24. In this embodiment, the second disinfection component 242 adopts a UV lamp, which can effectively kill bacteria and viruses that may exist in the water, ensuring the safety of the user's drinking water. Next, in this embodiment, a first disinfection component 25 is set between the refrigeration component 221 and the first reversing valve 23. In this embodiment, the first disinfection component 25 adopts a flow-through UV lamp. This setting ensures that the water after refrigeration is disinfected again by ultraviolet light, eliminating the risk of microbial contamination that may occur during the refrigeration process, and providing users with a cleaner and healthier source of cold drinking water.
[0058] Example 4:
[0059] This embodiment includes features of Embodiment 3, but differs from Embodiment 3 in that, by setting a second reversing valve 311 in the valve body assembly 31, water flowing from the inlet pipe 2 to the valve body assembly 31 must pass through both the first reversing valve 23 and the second reversing valve 311, effectively preventing cross-contamination between different water paths and also preventing the coffee machine from being affected if one of the reversing valves malfunctions. Furthermore, by setting a water pumping assembly 3121 on the third pipe 312 (in this embodiment, the water pumping assembly 3121 is a water pump), this configuration can not only extract an appropriate amount of water as needed... Water is available for use, and when the water pump is not running, it can also stop the water flow to prevent further water leakage, while also entering a pressurized state to protect the water pump from unnecessary damage. In addition, by installing a flow meter assembly 3131 and a high-pressure pump assembly 3132 in the fourth pipe 313, precise control and efficient transmission of water flow are ensured. The flow meter assembly 3131 can monitor and adjust the amount of water passing through the heating assembly 32, while the high-pressure pump assembly 3132 provides sufficient pressure so that the water can quickly reach the heating assembly 32 and be made into hot coffee or hot water to meet the user's immediate needs.
[0060] Example 5:
[0061] This embodiment includes features of Embodiment 4, but differs from Embodiment 4 in that it sets up a fifth pipe 332 and a sixth pipe 333. This allows water to be transported through the fifth pipe 332 and coffee to be transported through the sixth pipe 333, ensuring the independence of the two liquid paths, avoiding cross-contamination, and improving water safety and beverage purity.
[0062] Example 6:
[0063] This embodiment includes features of Embodiment 5, but differs from Embodiment 5 in that a high-pressure reversing valve 331 connected to the heating assembly 32 is provided in the switching component 33. Furthermore, both the fifth pipe 332 and the sixth pipe 333 are connected to the high-pressure reversing valve 331 and the liquid outlet 34, enabling water to be transported through the fifth pipe 332 and coffee to be transported through the sixth pipe 333. This ensures the independence of the two liquid paths, avoids cross-contamination, and improves water safety and beverage purity. Further, the fifth pipe 332 is connected to the third pipe 34. The third reversing valve 3321, which connects 12, allows cold water to directly enter the third pipe 312 through the second reversing valve 311, and then enter the fifth pipe 332 from the third pipe 312, finally flowing out from the outlet 34. This reduces the flow path of the cold water and effectively improves the water output efficiency. Furthermore, by setting the brewing assembly 3331 in the sixth pipe 333, the brewing assembly 3331, in conjunction with the high-pressure reversing valve 331, can achieve a highly efficient coffee brewing process. This not only ensures the taste and quality of the coffee but also effectively improves the coffee production efficiency.
[0064] Example 7:
[0065] This embodiment incorporates features of Embodiment Six, but differs from Embodiment Six in that it incorporates a filter assembly 4 between the water inlet 1 and the liquid inlet pipe 2. This effectively solves the problem of impurities in the water source, ensuring the purity of the water entering the coffee machine. Furthermore, the filter assembly 4 includes a first filter element 41, a second filter element 42 located downstream of the first filter element 41, and a booster pump valve assembly 43 located between the two and used to drive water into the water inlet 1. The booster pump valve assembly 43 ensures stable water supply even under low water pressure conditions. In this embodiment, the first filter element 41 is a composite filter element, and the second filter element 42 is an RO (reverse osmosis) filter element. This not only effectively removes particulate matter, residual chlorine, and other harmful substances from the water but also provides deeper purification, ensuring optimal water quality for coffee brewing.
[0066] Example 8:
[0067] This embodiment includes features of Embodiment Seven, but differs from Embodiment Seven in that, in this embodiment, a waste outlet 44 is provided in the filter assembly 4, and the second filter element 42 is connected to the waste outlet 44, thereby allowing the filter assembly 4 to discharge waste generated during the filtration process in a timely manner, maintaining the cleanliness and hygiene of the system; in addition, by providing an air vent valve 3133 on the fourth pipe 313 that connects the heating assembly 32 and the waste outlet 44, the air vent valve 3133 can not only remove the gas generated during the heating process, but also completely drain the water in the heating assembly 32 when it is not in use for maintenance or for a long time, avoiding the decrease in heating efficiency and potential safety hazards caused by scale accumulation, thereby enhancing the reliability and safety of the coffee machine.
[0068] Example 9:
[0069] This embodiment includes features of Embodiment Eight, but differs from Embodiment Eight in that it provides a stable cold water supply interface for external devices by setting a cold water outlet 5. Whether it's other appliances in a home kitchen or coffee-making auxiliary equipment in a commercial environment, they can directly obtain the required cold water from the cold water outlet 5 without the need for additional cooling devices. This not only meets the user's needs in different scenarios but also improves the convenience and efficiency of use. Furthermore, the third pipe 312 is equipped with a three-way component 3122 connected to both the cold water outlet 5 and the switching component 33, used to control the flow of cold water to cold water outlet. The water outlet 5 or the liquid outlet 34 is connected via the switching component 33. This configuration allows for flexible supply and use of cold water in the third pipe 3. Furthermore, since there is no control valve for the cold water outlet 5 in this embodiment, a plug is installed at the cold water outlet 5 to prevent cold water from flowing out when the outlet 5 is not in use. In addition, when the cold water outlet 5 is not in use, the plug can also effectively seal the outlet to prevent dust and other impurities from entering the internal pipes, keeping the system clean and hygienic. This configuration not only protects the internal components of the coffee machine from contamination but also simplifies the user's daily maintenance.
[0070] Example 10:
[0071] This embodiment includes the features of Embodiment Nine. The difference between this embodiment and Embodiment Nine is that the refrigeration component 221 in this embodiment can achieve a high-efficiency refrigeration effect through a compressor. The application of the compressor can quickly reduce the water temperature and provide readily available low-temperature cold water, which is particularly suitable for making beverages such as cold brew coffee that require high temperature. In addition, in some other embodiments, the refrigeration component 221 can also use an electronic ice chamber for refrigeration. The electronic ice chamber has the characteristics of compact structure and low energy consumption, and is suitable for situations that require maintaining a low-temperature environment for a long time.
[0072] Example 11:
[0073] This embodiment includes all the features of embodiments one to ten. In this embodiment, room temperature water first enters through the water inlet 1 and undergoes deep purification through the first filter element 41 and the second filter element 42 in the filter assembly 4. At the same time, it flows through the booster pump valve assembly 43 to ensure a stable water supply pressure, and then flows into and is stored in the water storage chamber 24.
[0074] When the user selects the cold water mode, room temperature water flows from the water storage chamber 24 to the second pipe 22. In the second pipe 22, the water flows through the cooling component 221 for cooling treatment to become cold water. Then, the cold water enters the third pipe 312 through the first reversing valve 23 and the second reversing valve 311. At this time, the third reversing valve 3321 in the switching component 33 switches the path to the fifth pipe 332, making the third pipe 312 and the fifth pipe 332 connected. The cold water can then flow smoothly through the fifth pipe 332 from the outlet 34, providing the user with immediate cold water. At this time, the cold water outlet 5 is blocked by a plug, so cold water will not flow out from the cold water outlet 5.
[0075] When the user selects room temperature water, the room temperature water flows out of the water storage chamber 24 into the first pipe 21. Then, the room temperature water enters the fourth pipe 313 through the first reversing valve 23 and the second reversing valve 311, and flows sequentially through the flow meter assembly 3131, the high pressure pump assembly 3132, the vent valve 3133, the heating assembly 32, the high pressure reversing valve 331, and the third reversing valve 3321. At this time, the heating assembly 32 turns off the heating function. Then, the room temperature water enters the fifth pipe 332 through the third reversing valve 3321, and then flows out from the outlet 34.
[0076] When the user selects hot water, room temperature water enters the fourth pipe 313 through the first reversing valve 23 and the second reversing valve 311, and flows sequentially through the flow meter assembly 3131, the high pressure pump assembly 3132, the vent valve 3133, the heating assembly 32, the high pressure reversing valve 331 and the third reversing valve 3321. At this time, the heating assembly 32 turns on to heat the room temperature water into hot water, and the hot water finally enters the fifth pipe 332 through the third reversing valve 3321, and then flows out from the outlet 34.
[0077] When a user wants to make hot brew coffee, room temperature water enters the fourth pipe 313 through the first reversing valve 23 and the second reversing valve 311, and flows sequentially through the flow meter assembly 3131, the high pressure pump assembly 3132, the vent valve 3133, the heating assembly 32, and the high pressure reversing valve 331. At this time, the heating assembly 32 turns on to heat the room temperature water into hot water, and the high pressure reversing valve 331 connects the fourth pipe 313 and the sixth pipe 333. The heated hot water flows into the sixth pipe 333 through the high pressure reversing valve 331, and forms hot brew coffee through the brewing assembly 3331, which flows out from the outlet 34.
[0078] When a user wants to make cold brew coffee, room temperature water flows from the water storage chamber 24 to the second pipe 22. In the second pipe 22, the water flows through the cooling component 221 to be cooled into cold water. Then, the cold water enters the fourth pipe 313 through the first reversing valve 23 and the second reversing valve 311, and flows sequentially through the flow meter component 3131, the high-pressure pump component 3132, the vent valve 3133, the heating component 32, and the high-pressure reversing valve 331. At this time, the heating component 32 stops heating, and the high-pressure reversing valve 331 connects the fourth pipe 313 and the sixth pipe 333, so that the cold water can flow into the sixth pipe 333 through the high-pressure reversing valve 331, and form cold brew coffee through the brewing component 3331, which flows out from the liquid outlet 34.
[0079] When a user wants to connect to an external device through the cold water outlet 5 to supply cold water to the external device, the plug needs to be removed from the cold water outlet 5 first. Then, room temperature water flows out of the water storage chamber 24 to the second pipe 22. In the second pipe 22, the water flows through the cooling component 221 to be cooled and become cold water. Then, the cold water enters the third pipe 312 through the first reversing valve 23 and the second reversing valve 311. At this time, the third reversing valve 3321 in the switching component 33 blocks the fifth pipe 332 to prevent cold water from entering the fifth pipe 332. At this time, the cold water will flow to the cold water outlet 5 through the three-way component 3122 and be output to the external device.
