This configuration solves the problem that most coffee machines on the market are limited to the hot extraction function, so that users can enjoy cold-brewed coffee without relying on additional equipment or waiting for a long time to cool down. Furthermore, the water inlet component 3 in the present invention can also directly provide room temperature water, and transport cold water or room temperature water to the liquid outlet component 2 through the reversing component 4, and cooperate with the reversing component 4 to control the liquid outlet 21 to output coffee or water, thereby realizing The liquid outlet component 2 outputs cold water or room temperature water, while the heating component 5 is responsible for providing hot water to the liquid outlet component 2, thereby realizing the direct output of cold water, room temperature water and hot water of the coffee machine, meeting the diverse needs of users; further, the addition of the reversing component 4 enables the liquid outlet component 2 to flexibly switch the output between water and coffee, thereby increasing the functional diversity of the coffee machine. Users can directly use the water of different temperatures provided by the coffee machine to adjust the coffee concentration to match their personal taste preferences, or when there is no need to make coffee, directly obtain drinking water of the required temperature from the coffee machine for other purposes. This setting effectively reduces the dependence on additional equipment and reduces The number of equipment and space occupied in the kitchen or office space; further, when the user needs to use cold water or normal temperature water, the cold water or normal temperature water delivered by the water inlet component 3 passes through the reversing component 4, and the water delivery pipeline is switched to the liquid outlet component 2 through the reversing component 4, thereby realizing the output of cold water or normal temperature water; when the user needs to use hot water, the normal temperature water delivered by the water inlet component 3 passes through the reversing component 4 to control the heating component 5 in the heating state, and then continues to switch the water delivery pipeline to the liquid outlet component 2 through the reversing component 4, thereby realizing the output of hot water; in some embodiments, normal temperature water can also be controlled by the reversing component 4 to enter the heating component 5 in the closed state. The water inlet component 3 controls the heating component 5 in the heating state, and continues to switch the pipeline for conveying water to the liquid outlet component 2 through the reversing component 4, thereby realizing the output of room temperature water; when the user needs to drink hot-brewed coffee, the room temperature water conveyed by the water inlet component 3 enters the heating component 5 in the heating state through the reversing component 4, and continues to switch the pipeline through the reversing component 4 to the pipeline for outputting coffee from the liquid outlet component 2, thereby realizing the output of hot-brewed coffee; when the user needs to drink cold-brewed coffee, the cold water conveyed by the water inlet component 3 enters the heating component 5 in the closed state through the reversing component 4, and continues to switch the pipeline through the reversing component 4 to the pipeline for outputting coffee from the liquid outlet component 2, thereby realizing the output of cold-brewed coffee.

[0037] Further, such as Figure 1-15A multifunctional coffee machine is shown, wherein the water inlet component 3 includes a water inlet 31, a water tank 33 connecting the water inlet 31 and the reversing component 4, and a refrigeration component 32 connected between the water tank 33 and the reversing component 4, the water tank 33 is provided with a first water outlet 331 and a second water outlet 332 both connected to the reversing component 4, and the refrigeration component 32 is connected between the second water outlet 332 and the reversing component 4.

[0038] The present invention provides a water inlet 31 and a water tank 33, and makes the water inlet 31 and the water tank 33 cooperate, so as to not only provide a stable water source for the coffee machine, but also utilize the water tank 33 to store a certain amount of water, thereby ensuring the continuity of water supply even when used continuously for a short period of time; further, the water tank 33 is provided with a first water outlet 331 and a second water outlet 332, both of which are connected to the reversing component 4, and a refrigeration component 32 is provided between the second water outlet 332 and the reversing component 4.

[0040] The present invention provides a first water inlet 22 and a second water inlet 23 connected to the reversing component 4 on the liquid outlet component 2, and a brewing component 24 is provided between the second water inlet 23 and the liquid outlet 21. This arrangement enables the reversing component 4 to switch water to the second water inlet 23 when making coffee, and complete the coffee extraction by cooperating with the brewing component 24; further, when the user only needs water, the reversing component 4 can switch the water flow to the first water inlet 22, so that the water is directly output from the liquid outlet 21 as drinking water. This arrangement enhances the functional diversity of the coffee machine, while simplifying the operating process, making the user experience smoother.

[0041] Further, such as Figure 1-15A multifunctional coffee machine is shown, wherein the liquid outlet component 2 also includes a first liquid outlet component 25 for water intake, and a second liquid outlet component 26 located below the first liquid outlet component 25, the first water inlet 22 and the second water inlet 23 are respectively located in the first liquid outlet component 25, the liquid outlet 21 and the brewing component 24 are located in the second liquid outlet component 26, and the second liquid outlet component 26 is detachably connected to the first liquid outlet component 25.

[0042] The present invention arranges the first water inlet 22 and the second water inlet 23 in the first liquid outlet component 25, and arranges the liquid outlet 21 and the brewing component 24 in the second liquid outlet component 26. In addition, a detachable connection is adopted between the second liquid outlet component 26 and the first liquid outlet component 25. This arrangement allows the user to easily disassemble the second liquid outlet component 26 and remove the brewing component 24 when he needs to directly obtain drinking water, and then reinstall the second liquid outlet component 26 back into the first liquid outlet component 25, so as to achieve the output of drinking water. When the user needs to obtain coffee, he only needs to disassemble the second liquid outlet component 26 and install the brewing component 24, and then reinstall the second liquid outlet component 26 into the first liquid outlet component 25 to achieve the output of coffee. Furthermore, this arrangement not only makes it convenient for the user to replace or clean the brewing component 24, but also provides convenience for maintenance work.

[0043] Further, such as Figure 1-15 A multifunctional coffee machine is shown, wherein the reversing assembly 4 includes a first reversing valve assembly 41 connected to the water inlet assembly 3, and a second reversing valve assembly 42 respectively connected to the first water inlet 22, the second water inlet 23, and the first reversing valve assembly 41, the heating assembly 5 is connected between the first reversing valve assembly 41 and the second reversing valve assembly 42, and the first reversing valve assembly 41 is connected to the first water inlet 22.

[0044] The present invention provides a first reversing valve assembly 41, and a second reversing valve assembly 42 respectively connected to the first water inlet 22, the second water inlet 23 and the first reversing valve assembly 41, and connects the heating assembly 5 between the first reversing valve assembly 41 and the second reversing valve assembly 42, so that cold water or normal temperature water can be delivered to the second reversing valve assembly 42 through the heating assembly 5 as needed, and then the second reversing valve assembly 42 can choose to deliver it to the first water inlet 22 or the second water inlet 23, so as to realize the function of outputting water and coffee, wherein when cold water flows through the heating assembly 5, the heating assembly 5 will not start the heating function, so as to ensure that the cold water maintains the original temperature, and then, through the second reversing valve assembly 5, the heating function of the heating assembly 5 is turned on. The valve assembly 42 can flexibly choose whether to directly output hot water or cold water from the first water inlet 22, or to guide the water flow to the second water inlet 23 for making cold brew coffee or hot brew coffee; further, through the setting of the first reversing valve assembly 41 connected to the first water inlet 22, cold water can also be directly transported to the first water inlet 22 to directly output cold water without passing through the heating assembly 5 and the second reversing valve assembly 42, thereby effectively reducing the flow path of cold water, improving efficiency and reducing energy consumption; further, the second reversing valve assembly 42 is a high-pressure reversing valve, and this setting ensures that the water flow has sufficient pressure to flow to the brewing assembly 24 to meet the water flow pressure requirement when brewing coffee.

[0045] Further, such as Figure 1-15 A multifunctional coffee machine is shown, wherein the coffee machine body 1 also includes a cold water outlet 6 connected to the first reversing valve assembly 41, and the reversing assembly 4 also includes a third reversing valve assembly 43 respectively connected to the first reversing valve assembly 41, the first water inlet 22, the cold water outlet 6 and the second reversing valve assembly 42.

[0046] The present invention is provided with a cold water outlet 6 that can be used to connect to an external device and provide cold water to the external device. This arrangement enables the multifunctional coffee machine to not only meet its own functional requirements, but also serve as a cold water supply source for other devices, thereby expanding its scope of application; further, by providing a third reversing valve assembly 43 in the reversing assembly 4, the third reversing valve assembly 43 is respectively connected to the first reversing valve assembly 41, the first water inlet 22, the cold water outlet 6 and the second reversing valve assembly 42, so that the third reversing valve assembly 43 is used to select whether to direct cold water to the first water inlet 22 to obtain directly available drinking water, or to supply cold water to the cold water outlet 6 for use by an external device. This arrangement enhances the functional diversity and practicality of the coffee machine, while simplifying the user's operating procedures; further, in some embodiments, the cold water outlet 6 is also provided with a plug, which can be used to plug the cold water outlet 6 when water is not needed to be discharged.

[0047] Further, such as Figure 1-15A multifunctional coffee machine is shown, wherein the water inlet component 3 also includes a filter component 34 connecting the water inlet 31 and the water tank 33, and a switching valve 35 respectively connected to the first water outlet 331, the second water outlet 332, and the reversing component 4, and the water tank 33 is also provided with a disinfection component 333 and a water level detection component 334.

[0048] The present invention ensures the purity of water entering the system by providing a filter component 34 connecting the water inlet 31 and the water tank 33 in the water inlet component 3, thereby preventing impurities from affecting the taste of the coffee or damaging the internal structure; further, by providing a switching valve 35 connected to the first water outlet 331, the second water outlet 332 and the reversing component 4 in the water tank 33, it is used to select whether to supply cold water or normal temperature water to the reversing component 4, thereby ensuring effective control of the output of cold water and normal temperature water; further, by providing a disinfection component 333 and a water level detection component 334 inside the water tank 33, not only can the sanitary conditions in the water tank 33 be guaranteed, but also the water tank 33 can be prevented from overflowing or insufficient water, thereby ensuring a continuous and stable water supply.

[0049] Further, such as Figure 1-15 A multifunctional coffee machine is shown, wherein the coffee machine body 1 also includes a waste water outlet 7 connected to the filter assembly 34, an emptying valve assembly 8 connected to the heating assembly 5, a first pumping assembly 9 connected between the first reversing valve assembly 41 and the third reversing valve assembly 43, a flow meter assembly 10 connected between the heating assembly 5 and the first reversing valve assembly 41, and a second pumping assembly 11 connected between the heating assembly 5 and the flow meter assembly 10, and the emptying valve assembly 8 is connected to the waste water outlet 7.

[0050] The present invention ensures that the waste water generated during the filtering process can be effectively discharged by setting a waste water outlet 7 connected to the filter assembly 34, thereby avoiding the problem of internal water accumulation, thereby maintaining the cleanliness and hygiene of the internal environment of the coffee machine; further, by setting an emptying valve assembly 8 connected to the heating assembly 5, the emptying valve assembly 8 is connected to the waste water outlet 7, so that the residual water and hot air in the heating assembly 5 can be smoothly discharged through the waste water outlet 7. This arrangement not only helps to prevent the formation of scale when it is not used for a long time, but also can quickly empty the water in the system after cleaning or maintenance, thereby ensuring the hygiene and safety of the equipment; further, by setting a connection between the first reversing valve assembly 41 and the third reversing valve assembly 42, the coffee machine can be cleaned and maintained. The first pumping assembly 9 between the components 43, and the flow meter assembly 10 and the second pumping assembly 11 connected between the heating component 5 and the first reversing valve assembly 41, realize the precise control of the water flow direction and flow rate, and ensure the stability of water supply in different working modes; further, the first pumping assembly 9 ensures the smooth flow of water from the first reversing valve assembly 41 to the third reversing valve assembly 43; further, the flow meter assembly 10 can accurately monitor the amount of water passing through the heating component 5, so that the heating process is more precise and controllable, and the second pumping assembly 11 further ensures the stability of the hot water supply. This setting effectively improves the working efficiency and response speed of the coffee machine.

[0051] Further, such as Figure 1-16 A multifunctional coffee machine is shown, wherein the coffee machine body 1 also includes a tray 12, and the coffee machine body 1 is also provided with a placement cavity 13 located on one side of the liquid outlet component 2, and the placement cavity 13 is provided with a plurality of placement areas of different heights for installing the tray 12, and the cross-section of the placement cavity 13 gradually increases from the side of the liquid outlet component 2 downward.

[0052] The present invention provides a placement cavity 13 located on one side of the liquid outlet component 2 in the coffee machine body 1, and cooperates with the tray 12 for placing containers; further, the placement cavity 13 is provided with a plurality of placement areas of different heights for installing the tray 12, and its cross-section gradually increases from the side of the liquid outlet component 2 downward, so that the user can flexibly adjust the installation position of the tray 12 according to the size and height of the container, so that larger or higher containers can be placed in the lower area, and smaller or shorter containers can be placed near the liquid outlet 21, and the container is placed too far away from the liquid outlet 21 to cause liquid splashing.

[0053] Further, such as Figure 1-16 The working method of the multifunctional coffee machine shown comprises the following steps: S1, the reversing component 4 controls the water inlet component 3 to output cold water or normal temperature water; S2, when hot water or hot coffee is needed, the heating component 5 starts heating; S3, the reversing component 4 can input cold water, hot water or room temperature water into the liquid outlet component 2, and control the liquid outlet 21 to output coffee or water.

[0054] The present invention provides a working method of a multifunctional coffee machine, the core of which is to realize the function of flexibly switching the output of cold-brewed coffee, hot-brewed coffee, cold water, hot water and normal-temperature water on the same device by arranging a water inlet component 3 capable of providing cold water or normal-temperature water, a heating component 5 capable of heating liquid and a reversing component 4 capable of controlling the liquid outlet component 2 to output drinking water or coffee, so as to meet the user's needs for drinking water and coffee at different temperatures; further, when the user chooses to output cold-brewed coffee, the water inlet component 3 will convey the cold water to the reversing component 4, and the reversing component 4 will directly guide the cold water into the liquid outlet component 2, and finally output the cold-brewed coffee from the liquid outlet 21, and the heating component 5 is in a state of stopping heating during the whole process; further, when the user chooses to output hot-brewed coffee, the water inlet component 3 will convey the normal-temperature water to the reversing component 4, and heat it through the heating component 5, and then the heated water will enter the liquid outlet component 2, and finally output the hot-brewed coffee from the liquid outlet 21; further, When the user chooses to output cold water, the water inlet component 3 will convey the cold water to the reversing component 4, and the reversing component 4 will directly guide the cold water into the liquid outlet component 2, and finally output the cold water directly from the liquid outlet 21; further, when the user chooses to output hot water, the water inlet component 3 will convey the normal temperature water to the reversing component 4, and heat it through the heating component 5, and then the heated water will enter the liquid outlet component 2, and finally output the hot water directly from the liquid outlet 21; further, this setting not only meets the user's needs for drinking water and coffee at different temperatures, but also effectively reduces the use of other equipment by integrating the output functions of drinking water and coffee into one, thereby optimizing the space utilization efficiency; further, when the user chooses to output normal temperature water, the water inlet component 3 will convey the normal temperature water to the reversing component 4, and the reversing component 4 will directly guide the normal temperature water into the liquid outlet component 2, and finally output the normal temperature water directly from the liquid outlet 21, and the heating component 5 is in a stopped heating state during the whole process.

[0055] like Figure 1-16 As shown, the implementation mode of the present invention is as follows: Embodiment 1: This embodiment provides a multifunctional coffee machine, which integrates the functions of cold brewing, hot brewing, hot water output, cold water output and normal temperature water output. The coffee machine is fed with water by the water inlet component 3 and supplies cold water or normal temperature water to the liquid outlet component 2. Then the water flow is directed to different processing paths according to the user's selection, and finally the required coffee or water is output from the liquid outlet component 2.

[0056] When the user wants to make a cup of hot brewed coffee, the room temperature water first passes through the water inlet assembly 3 to the heating assembly 5. At this time, the heating assembly 5 starts to quickly heat the water flowing through it to a temperature suitable for brewing coffee. The heated hot water continues to move forward, and when it passes through the reversing assembly 4, since the user has selected the coffee making mode, the reversing assembly 4 switches the pipeline to the pipeline for delivering coffee from the liquid outlet assembly 2, ensuring that the hot water flows into the area where the coffee powder is located for extraction, so that the hot brewed coffee flows out of the liquid outlet 21.

[0057] When the user wants to drink cold brew coffee, similarly, room temperature water reaches the refrigeration component 32 through the water inlet component 3, and the refrigeration component 32 performs cooling treatment. Then the cold water reaches the heating component 5. During the cold brewing process, the heating component 5 is in a closed state and does not perform heating operation, so that the cold water directly passes through the heating component 5 and then enters the liquid outlet component 2 through the reversing component 4. At this time, the reversing component 4 switches the pipeline to the pipeline for conveying coffee from the liquid outlet component 2, ensuring that the cold water flows into the area where the coffee powder is located for extraction, so that the cold brew coffee flows out of the liquid outlet 21.

[0058] In addition, the coffee machine can also provide drinking water at different temperatures.

[0059] When the user needs to use cold water, the cold water in the water inlet component 3 does not need to pass through the heating component 5, but directly passes through the reversing component 4, and the reversing component 4 switches the water delivery pipeline to the liquid outlet 21, thereby realizing the output of cold water.

[0060] When the user needs to use hot water, the room temperature water of the water inlet component 3 will reach the heating component 5 in the heating state through the reversing component 4.
