Description

Technical Field

[0001] This invention relates to the field of coffee machines, and more particularly to a multi-functional coffee machine. Background Technology

[0002] As a common household and commercial appliance, the performance and user experience of coffee machines are receiving increasing attention. However, existing coffee machine technology still has several shortcomings in long-term use: First, existing coffee machines are limited in function, only able to make coffee and lacking the ability to dispense cold or hot water like a water dispenser.

[0003] Secondly, during the coffee extraction process, high-temperature water channels often generate steam. If the water vapor is not effectively separated, it can easily cause steam to splash at the water outlet, which not only affects the stability of the beverage preparation but may also pose a risk of burns to the user. At the same time, steam accumulation in the pipeline can easily form air blockage, resulting in poor water flow or intermittent water output, which affects the extraction effect.

[0004] Furthermore, most existing coffee machine drawers are built-in, requiring the front panel, top panel, or side panel to be opened before the drawer can be removed for disassembly, cleaning, or replacement, which is very inconvenient. In addition, existing drawer bodies are difficult to completely disassemble for cleaning; only the outermost filter can be cleaned.

[0005] Furthermore, most coffee machines on the market currently use a single water supply method, either supporting bottled water supply or direct connection to drinking water pipes. They cannot flexibly switch water sources according to the user's actual usage scenario, which limits the applicable scenarios and installation flexibility of the equipment.

[0006] Therefore, how to effectively solve the problems of limited liquid output function, water vapor interference, inconvenient maintenance of filter components, and limited water supply methods has become a direction that needs to be improved by those skilled in the art. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies by providing a multi-functional coffee machine, including a main body and further comprising...

[0010] Optionally, the second water vapor separation component includes a cold water inlet, a cold water outlet, and a rigid pipe. The two ends of the rigid pipe are connected to the cold water inlet and the cold water outlet, respectively, to form a cold water flow channel that is not connected to the second water storage chamber. The outer wall of the rigid pipe is provided with a partition plate, which divides the second water storage chamber into a first chamber and a second chamber. The first chamber is used to store hot water, and the second chamber is connected to both the first chamber and the outside, so as to discharge the hot water vapor in the first chamber to the outside.

[0011] Optionally, the second water storage chamber is provided with a siphon layer tube, and the upper end of the second hot water outlet is inserted into the siphon layer tube, forming a siphon channel between the two. The hot water in the second water storage chamber is siphoned into the second hot water outlet through the siphon channel.

[0012] Optionally, the brewing and filtering assembly includes The drawer body is slidably connected to the front panel of the machine body, and the drawer body is recessed to form a first receiving cavity; The receiving component is detachably accommodated in the first receiving cavity and abuts against the drawer body from the top and bottom.

The third connecting ring wall forms a second opening around the second opening, and the liquid outlet is inserted into the second opening and abuts against the connecting frame. The dispensing component includes a silicone pad, a connecting shaft, and a dispensing head. The upper ends of the silicone pad and the connecting shaft are detachably connected. The connecting shaft is provided with a plurality of axially extending dispensing grooves. The dispensing head is provided with a plurality of third openings. The third openings are aligned vertically with the dispensing grooves. The silicone pad is bowl-shaped and is located above the connecting frame, forming a gap between the silicone pad and the connecting frame for coffee liquid to flow out, so that the coffee liquid flows from the dispensing groove to the third opening after passing through the gap.

[0014] Optionally, the chilled water assembly includes The first water inlet pipe is used to connect bottled water. The second water inlet pipe is used to connect to a direct drinking water pipe or a tap water pipe; A water outlet pipe, which is used to dissipate water; A three-way pipe, wherein the three ends of the three-way pipe are respectively connected to the first water inlet pipe, the second water inlet pipe and the water outlet pipe; A switching device, which is a rubber stopper, a solenoid valve, or a rotary valve, wherein the rubber stopper is detachably installed at the port of the first water inlet pipe or the second water inlet pipe; the solenoid valve is installed on the first water inlet pipe and the second water inlet pipe; and the rotary valve is connected to the three-way pipe to rotate and switch the water inlet path.

[0015] Optionally, when the switching device is a rubber stopper, one end of the second water inlet pipe is connected to a negative pressure valve, the negative pressure valve includes a connection port, and the rubber stopper is adapted to be detachably connected to the connection port; When the switching device is a solenoid valve, the machine body is equipped with a controller and a control panel.

The controller is electrically connected to both the control panel and the solenoid valve. The three-way pipe includes a first inlet, a second inlet, and an outlet. The first inlet is connected to the first inlet pipe, the second inlet is connected to the second inlet pipe, and the outlet is connected to both the first and second inlets. When the switching device is a rotary valve, the rotary valve rotates to block either the first or second inlet, thereby switching the water inlet paths of the first and second inlet pipes.

[0016] Optionally, the body is connected to a drawer body. When the second water inlet pipe is connected to the tap water pipe, the drawer body is simultaneously connected to the second water inlet pipe and the tap water pipe, so that the tap water is filtered to a state that is drinkable before being delivered to the second water inlet pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By integrating a water dispensing unit, including both cold and hot water components, into the coffee machine, the machine is no longer limited to making coffee but integrates the functions of a water dispenser, supplying both cold and hot water. This solves the problem of the limited functionality of existing coffee machines. Users no longer need to purchase additional water dispensing equipment to meet their daily needs for drinking cold water or brewing hot beverages, greatly improving the practicality and ease of use of the coffee machine and expanding its applicability in home, office, and commercial settings.

[0018] 2. The top of the machine body is equipped with an exhaust port connecting to the outside. Both the first and second exhaust pipes are connected to the exhaust port, allowing high-temperature steam to be discharged. A first steam separator is installed between the hot water assembly and the brewing and filtering assembly. The high-temperature steam generated during the heating process is pre-exported and discharged outside the machine through the first exhaust pipe, effectively preventing hot water with a large amount of steam from entering the brewing and filtering assembly and causing coffee powder to splash. At the same time, because the steam is separated in time, there is no air resistance due to steam accumulation in the pipes, ensuring a continuous, stable, and uninterrupted water flow, thereby guaranteeing the uniformity of the coffee extraction process and the quality of the coffee liquid.

[0019] 3. A second water vapor separation component and its second exhaust pipe are installed between the hot water component and the cold water component. This can export the high-temperature steam generated during the heating process in advance and discharge it outside the machine, preventing steam from flowing back into the cold water pipe and avoiding steam splashing at the hot water inlet, thus reducing the safety risk of users being scalded; and preventing discontinuous water output.

[0020] 4. By using a partition plate to form an independent steam guiding chamber, some of the steam generated by the hot water is discharged through the second exhaust pipe, while some enters the second chamber and is then discharged, increasing the exhaust channels and improving steam exhaust efficiency. Integrating the rigid pipes with the partition plate ensures the structural stability of the hot and cold passages and saves internal space in the second water storage chamber.

[0021] 5. A siphon channel is formed by the nested structure between the siphon layer tube and the second hot water outlet. The narrow siphon channel not only blocks steam from entering, but also draws water upward from a lower position to the second hot water outlet through capillary force, so that the water flow in the channel remains stable and reduces water level fluctuations. At the same time, capillary force can lock in the water and achieve the effect of no leakage after the water is turned off.

[0022] 6. The drawer body and front panel slide together to form a pull-out structure, allowing the entire drawer to be pulled out without opening the front or top cover, simplifying operation and improving ease of use. Simultaneously, the recessed first accommodating cavity provides a stable space for the receiving component, facilitating overall assembly and disassembly. The receiving component is detachably connected to the drawer body and abuts against it from top to bottom, ensuring assembly stability and allowing for multi-layer separation. This facilitates the individual removal and cleaning of the receiving component, solving the problem of cleaning the receiving component in existing technologies and improving cleaning thoroughness. The filter element is detachably connected to the receiving component and abuts against it from top to bottom, featuring a compact structure and easy assembly and disassembly. Users can remove the filter element for cleaning or replacement, preventing the accumulation of filter residue after long-term use and ensuring coffee liquid hygiene. The dispensing component is detachably connected to the bottom of the receiving component, enabling modular assembly and disassembly of the dispensing channel. Users can remove the dispensing component for cleaning at the same time, preventing residual stains inside the dispensing channel and further improving overall cleanliness.

[0023] 7. By setting up independent first and second water inlets and using a T-junction to connect the two inlets to the same outlet, the coffee machine achieves compatibility with three water sources: bottled water, direct drinking water, and tap water. The switching device offers three different cost and operation options: The rubber stopper is a purely mechanical manual sealing method, extremely low cost, suitable for users who do not frequently switch water sources. When switching water sources is required, one inlet pipe needs to be blocked and then the other connected; the solenoid valve, combined with electronic control, enables one-button automatic switching. During installation, both water sources are connected simultaneously, and subsequent switching requires no manual plugging or unplugging, offering a smarter experience; the knob valve allows manual rotation to directly block one of the water inlets, with a simple and reliable structure and no risk of lost rubber stoppers.

[0049] The technical solutions of various embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The accompanying drawings of the embodiments of the present invention provide a coordinate system XYZ, wherein the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0051] An embodiment of the present invention provides a multi-functional coffee machine, including a body, and further comprising: A drinking water unit, comprising a cold water component and a hot water component, wherein the cold water component is simultaneously connected to the hot water component and an external water source, and the hot water component includes a heating device 1 for heating cold water; The coffee unit includes a feeding and grinding assembly and a brewing and filtering assembly connected to the feeding and grinding assembly. The feeding and grinding assembly is used to grind coffee beans into coffee powder and deliver it to the brewing and filtering assembly. The brewing and filtering assembly is connected to the hot water assembly to brew the coffee powder and filter out coffee liquid. A first water vapor separation component is connected to both the hot water component and the brewing filter component. The first water vapor separation component includes a first exhaust pipe 2, which is connected to the hot water component to discharge hot water vapor. The second water vapor separation component is connected to both the hot water component and the cold water component. The second water vapor separation component includes a second exhaust pipe 3, which is connected to the hot water component to discharge hot water vapor.

[0052] like Figure 1 As shown, by integrating a water dispensing unit that includes both cold and hot water components into the coffee machine, the coffee machine is no longer limited to making coffee but integrates the functions of a water dispenser, capable of supplying both cold and hot water. This solves the problem of the limited functionality of existing coffee machines. Users no longer need to purchase additional water dispensing equipment to meet their daily needs for drinking cold water or brewing hot beverages, greatly improving the practicality and ease of use of the coffee machine and expanding its applicability in home, office, and commercial settings.

[0053] The feeding and grinding assembly includes a feeding chamber 34, a grinding device 35, and a conveying pipe 36 that are interconnected. The cover of the feeding chamber 34 is detachable or openable and closable and is mounted on the top plate of the machine body. After the user opens the cover of the feeding chamber 34 and puts in coffee beans, the coffee beans fall into the grinding device 35, which grinds the coffee beans into coffee powder. The conveying pipe 36 connects the grinding device 35 and the brewing and filtering assembly to transport the coffee powder to the brewing and filtering assembly. The brewing and filtering assembly is then connected to the hot water assembly to introduce hot water to complete the extraction. This realizes a fully automatic and integrated preparation process from coffee beans to coffee liquid, avoiding the tedious operation of manual grinding and brewing.

[0054] The top of the machine body is equipped with an exhaust port 37 that connects to the outside. The first exhaust pipe 2 and the second exhaust pipe 3 are both connected to the exhaust port 37, allowing high-temperature water vapor to be discharged from the exhaust port 37. A first water vapor separation component is installed between the hot water component and the brewing and filtering component. The high-temperature steam generated during the heating process is pre-exported and discharged outside the machine through the first exhaust pipe 2, effectively preventing hot water with a large amount of steam from entering the brewing and filtering component and causing coffee powder to splash. At the same time, because the steam is separated in time, the pipes will not accumulate steam and form air resistance, ensuring a continuous, stable, and uninterrupted water flow, thereby ensuring the uniformity of the coffee extraction process and the quality of the coffee liquid.

[0055] A second water vapor separation component and its second exhaust pipe 3 are installed between the hot water component and the cold water component. This can export the high-temperature steam generated during the heating process in advance and discharge it outside the machine, preventing steam from flowing back into the cold water pipe and avoiding steam splashing at the hot water inlet, thus reducing the safety risk of users being scalded; and preventing discontinuous water output.

[0056] like Figure 2 and Figure 3 As shown, optionally, the first water vapor separation component includes a first hot water inlet 4, a first hot water outlet 5, and a first water storage chamber 6 for storing water. The first hot water inlet 4 is connected to the first water storage chamber 6 to input hot water, the first hot water outlet 5 is connected to the first water storage chamber 6 to output hot water, and the first exhaust pipe 2 is located at the upper end of the first water storage chamber 6 and connected to the outside to discharge hot water vapor. like Figure 4 and Figure 5 As shown, the second water vapor separation assembly includes a second hot water inlet 7, a second hot water outlet 8, and a second water storage chamber 9 for storing water. The second hot water inlet 7 is connected to the second water storage chamber 9 to input hot water, and the second hot water outlet 8 is connected to the second water storage chamber 9 to output hot water. The second exhaust pipe 3 is located at the upper end of the second water storage chamber 9 and is connected to the outside to discharge hot water vapor.

[0057] The first hot water inlet 4 and the second hot water inlet 7 are connected to the heating device 1 via pipes (flexible or rigid pipes), thereby delivering heated hot water to the first water storage chamber 6 and the second water storage chamber 9. The water storage chambers provide buffer space and time for the steam from the hot water to escape, preventing hot water from being directly output to the outside from the heating device 1. The first hot water outlet 5 supplies water to the brewing and filtering assembly to brew coffee powder, and the second hot water outlet 8 directly dispenses water to external water containers (such as cups or kettles).

[0058] High-temperature water vapor is less dense than air. According to Archimedes' principle, fluids with lower density rise in fluids with higher density. Therefore, by combining the upward-facing first exhaust pipe 2 and the second exhaust pipe 3, the water vapor in the first water storage chamber 6 and the second water storage chamber 9 can be discharged upwards to the outside of the machine.

[0059] In summary, by setting up a water storage chamber to provide buffer space and time for hot water vapor to escape, and by using the exhaust port 37 located at the top to directly concentrate and discharge the water vapor upwards, the direction of water vapor emission is effectively guided, reducing steam resistance or steam splashing caused by the natural diffusion of water vapor in the surroundings, as is common in traditional equipment. At the same time, it significantly reduces the amount of unorganized escape of high-temperature water vapor into the equipment interior and surrounding environment, helping to keep the operating area dry and reducing the electrical safety hazard of short circuits caused by long-term moisture exposure of electrical components.

[0060] like Figure 3 and Figure 5 As shown, optionally, both the first water storage chamber 6 and the second water storage chamber 9 are provided with baffles 10. The baffles 10 are located on one side of the first hot water inlet 4 or the second hot water inlet 7 and are located on the hot water inlet path to reduce the impact force of hot water inlet. like Figure 3 and Figure 5 As shown, both the first water storage chamber 6 and the second water storage chamber 9 are provided with inclined guide portions 11. The two ends of the guide portion 11 are a first end 111 and a second end 112. The first end 111 is higher than the second end 112. The first end 111 is located below the baffle 10. The second end 112 is connected to the first hot water outlet 5 or the second hot water outlet 8.

[0061] Existing technologies typically control water flow through flow valves. When the flow valve opens, hot water entering the hot water inlet through the pipe generates an impact force. Baffle 10 buffers this impact force, reducing splashing and instantaneous vaporization, resulting in smoother vapor formation, facilitating orderly vapor separation, and preventing violent vapor diffusion caused by direct impact from high-temperature water flow.

[0062] The first end 111 is located below the baffle 10. After being buffered by the baffle 10, the hot water first flows downward to the first end 111, and then the inclined guide part 11 allows the hot water to flow smoothly to the second end 112 under the action of gravity. In the first water storage chamber 6, the upper part of the hot water outlet is level with the height of the second end 112, so that the hot water can flow directly into the hot water outlet and improve the brewing efficiency.

[0063] like Figure 6 , Figure 8 , Figure 10As shown, optionally, the second water vapor separation component includes a cold water inlet 12, a cold water outlet 13, and a rigid pipe 14. The two ends of the rigid pipe 14 are respectively connected to the cold water inlet 12 and the cold water outlet 13 to form a cold water flow channel that is not connected to the second water storage chamber 9. A partition plate 15 is provided on the outer wall of the rigid pipe 14. The partition plate 15 divides the second water storage chamber 9 into a first chamber 91 and a second chamber 92. The first chamber 91 is used to store hot water, and the second chamber 92 is connected to both the first chamber 91 and the outside to discharge the hot water vapor in the first chamber 91 to the outside.

[0064] By setting up an independent cold water channel, the user's cold water needs are met, while the cold water flow path is completely isolated from the hot water receiving chamber, preventing the mixing of cold and hot water. An independent steam guiding chamber is formed by the partition plate 15, allowing some of the steam generated by the hot water to be discharged through the second exhaust pipe 3, and some to enter the second chamber 92 before being discharged, increasing the exhaust channels and improving steam exhaust efficiency. Integrating the rigid pipe 14 with the partition plate 15 ensures the structural stability of the hot and cold channels while saving internal space in the receiving chamber.

[0065] like Figure 10 and Figure 11 As shown, the upper end of the partition plate 15 is provided with a first air inlet 911, and the lower end of the second chamber 92 is provided with a second air inlet 921. The first chamber 91 and the second chamber 92 are connected through the first air inlet 911, and the second chamber 92 is connected to the outside through the second air inlet 921. Water vapor first enters the second chamber 92 from the first air inlet 911, and then is discharged to the outside through the second air inlet 921, reducing the flow path and making exhaust more efficient.

[0066] like Figure 5 and Figure 7 As shown, optionally, the second water storage chamber 9 is provided with a siphon layer pipe 16, the upper end of the second hot water outlet 8 is inserted into the siphon layer pipe 16, and a siphon channel 161 is formed between the second water storage chamber 9 and the siphon layer pipe 161. The hot water in the second water storage chamber 9 is siphoned into the second hot water outlet 8 through the siphon channel 161.

[0067] In the second water vapor separation assembly, the upper end of the second hot water outlet 8 is higher than the second end 112 of the guide section 11, and the second end 112 of the guide section 11 is connected to the siphon channel 161. The siphon channel 161 is formed by the nested structure between the siphon layer tube 16 and the second hot water outlet 8. The narrow siphon channel 161 not only blocks steam from entering but also draws water upwards from a lower position into the second hot water outlet 8 through capillary force, maintaining a stable water flow and reducing water level fluctuations. Simultaneously, capillary force locks in the water, achieving a leak-free effect after the water is turned off.

[0068] like Figures 12 to 14 As shown, optionally, the brewing and filtering assembly includes: The drawer body 17 is slidably connected to the front panel 21 of the machine body, and the drawer body 17 is recessed to form a first receiving cavity; The receiving part 18 is detachably accommodated in the first receiving cavity and abuts against the drawer body 17 from the top and bottom. The receiving part 18 is recessed to form a second receiving cavity. The receiving part 18 is used to receive the filtered coffee liquid. The filter element 19 is detachably accommodated in the second receiving cavity and abuts against the receiving element 18 from above and below. The filter element 19 is used to filter coffee liquid. The liquid outlet 20 is detachably connected to the bottom of the receiving member 18, and the liquid outlet 20 is connected to the receiving member 18. The liquid outlet 20 is used to dispense liquid to an external container.

[0069] like Figure 18 and Figure 19 As shown, the drawer body 17 is slidably connected to the front panel 21 to form a pull-out structure. The drawer body 17 can be pulled out as a whole without opening the front cover or top cover of the machine, which simplifies the operation steps and improves the convenience of use. At the same time, the recessed first accommodating cavity provides a stable accommodating space for the receiving part 18, which is convenient for overall disassembly and assembly.

[0070] The receiving part 18 is detachably connected to the drawer body 17 and abuts against it from top to bottom, ensuring assembly stability. At the same time, it enables the separation of multiple layers, making it easy to remove the receiving part 18 for cleaning. This solves the problem that the receiving part 18 cannot be cleaned in the prior art and improves the thoroughness of cleaning.

[0071] The filter element 19 and the receiving element 18 are detachably connected and abut against each other, with a compact structure and easy disassembly and assembly. Users can remove the filter element 19 separately for cleaning or replacement, avoiding the accumulation of filter residue after long-term use and ensuring the hygiene of coffee liquid.

[0072] The liquid outlet component 20 is detachably connected to the bottom of the receiving component 18, enabling modular disassembly and assembly of the liquid outlet channel. Users can remove the liquid outlet component 20 for cleaning to avoid residual stains inside the liquid outlet channel and further improve the overall cleanliness.

[0073] like Figure 15 and Figure 16As shown, optionally, the receiving component 18 is provided with a first flange 181, and the drawer body 17 is provided with a connecting groove 1721, wherein the first flange 181 is accommodated in the connecting groove 1721. Through the cooperation of the first flange 181 and the connecting groove 1721, the receiving component 18 is quickly positioned and limited within the drawer body 17, preventing rotational displacement during use and improving assembly reliability and operational stability.

[0074] like Figure 14 As shown, optionally, a gripping block 191 is connected to the upper end of the filter element 19. A first limiting groove 1722 is recessed in the upper side wall of the first accommodating cavity, and a second limiting groove 182 is recessed in the upper side wall of the receiving element 18. The gripping block 191 is simultaneously confined within both the first limiting groove 1722 and the second limiting groove 182. The gripping block 191 cooperates with both the first limiting groove 1722 and the second limiting groove 182, which facilitates the user's placement and removal of the filter element 19 and achieves multiple limiting between the filter element 19, the receiving element 18, and the drawer body 17, preventing the filter element 19 from shaking or misaligning after assembly.

[0075] like Figure 15 and Figure 16 As shown, optionally, the inner wall of the first accommodating cavity is provided with a plurality of reinforcing ribs 1723, and the outer wall of the receiving member 18 is provided with a plurality of first clearance grooves 183. The first clearance grooves 183 are used to avoid the reinforcing ribs 1723, and the upper end of the reinforcing ribs 1723 is adapted to abut against the upper top wall of the first clearance grooves 183. The cooperation between the reinforcing ribs 1723 and the first clearance grooves 183 not only enhances the structural strength of the drawer body 17, but also achieves precise vertical positioning of the receiving member 18, preventing the receiving member 18 from sinking excessively, and also preventing the first flange 181 from being subjected to excessive force and breaking, thus ensuring structural stability.

[0076] like Figure 12 As shown, optionally, the drawer body 17 includes a push-pull portion 171 and a connecting portion 172. The bottom of the push-pull portion 171 is inclined to facilitate finger insertion, and the first accommodating cavity is located on the connecting portion 172. The inclined bottom design of the push-pull portion 171 is ergonomic, making it easier for users to insert their fingers and apply force, thus improving the comfort and convenience of the drawer operation.

[0077] like Figure 16As shown, optionally, a limiting block 1711 is provided on the upper wall of the push-pull part 171 near the connecting part 172. The limiting block 1711 has an inclined guide ramp 1712, and an abutment groove 1713 is provided at the upper end of the limiting block 1711. The abutment groove 1713 is located at the guide end of the guide ramp 1712, and the abutment groove 1713 is suitable for abutting against the external abutment post 33. Through the cooperation of the guide ramp 1712 and the abutment post 33, automatic guidance and positioning of the drawer body 17 during the pushing process are realized. After the abutment groove 1713 abuts against the abutment post 33, it can prevent the drawer body 17 from accidentally sliding out, improving the safety of use. At the same time, it provides a tactile feedback to remind the user that the drawer body 17 is installed in place.

[0078] like Figure 13 , Figure 15 , Figure 16 As shown, optionally, the bottom of the first accommodating cavity is provided with a first connecting ring wall 1724 protruding upward, the first connecting ring wall 1724 surrounds to form a first opening 1725, the bottom of the receiving member 18 is provided with a limiting step 184 and a second connecting ring wall 185 protruding downward along the limiting step 184, the second connecting ring wall 185 is inserted into the first opening 1725, and the upper end of the first connecting ring wall 1724 abuts against the bottom of the limiting step 184; The inner wall of the second connecting ring wall 185 is connected to a third connecting ring wall 186 and a connecting frame 187. The third connecting ring wall 186 and the second connecting ring wall 185 are coaxially arranged and connected to each other by the connecting frame 187. The third connecting ring wall 186 forms a second opening 188. The liquid outlet 20 is inserted into the second opening 188 and abuts against the connecting frame 187. like Figure 17 As shown, the dispensing component 20 includes a silicone pad 201, a connecting shaft 202, and a dispensing head 203. The upper ends of the silicone pad 201 and the connecting shaft 202 are detachably connected. The connecting shaft 202 is provided with a plurality of axially extending dispensing grooves 2021. The dispensing head 203 is provided with a plurality of third openings 2031. The third openings 2031 are vertically aligned with the dispensing grooves 2021. The silicone pad 201 is bowl-shaped and is located above the connecting frame 187, forming a gap between the silicone pad 201 and the connecting frame 187 for coffee liquid to flow out, so that the coffee liquid flows from the dispensing grooves 2021 to the third openings 2031 after passing through the gap.

[0079] The first connecting ring wall 1724 and the second connecting ring wall 185 are inserted and engaged, and together with the abutting action of the limiting step 184, the receiving part 18 and the drawer body 17 are positioned in both vertical and horizontal directions, which improves the stability of the assembly and prevents loosening during use.

[0080] The coaxial ring wall structure and connecting frame 187 form a stable installation interface for the liquid outlet 20, ensuring that the liquid outlet 20 is concentrically aligned with the receiving part 18 after insertion, thereby improving the smoothness and stability of liquid outlet in the circumferential direction.

[0081] The silicone pad 201 is made of food-grade material. The bowl-shaped silicone pad 201 acts as a buffer. The gap between the silicone pad 201 and the connecting bracket 187 allows the coffee liquid to flow out evenly. There are four liquid outlets 2021 and four corresponding third openings 2031. The liquid outlets 2021 and the third openings 2031 are aligned vertically to form a smooth liquid outlet channel, ensuring stable liquid output and facilitating cleaning.

[0082] like Figure 18 and Figure 19 As shown, the coffee machine includes a front panel 21, on which a mounting cavity 211 for mounting the drawer body 17 is provided. The mounting cavity 211 contains a sliding groove 212 and a second clearance groove 213. A second flange 1726 is provided on the connecting portion 172, and the second flange 1726 is slidably connected to the sliding groove 212. The second clearance groove 213 is used to avoid the grip block 191. The brewing and filtering assembly includes a spray device that brews coffee powder by spraying hot water. The spray device is located at the upper end of the drawer body 17, and an abutment post 33 is provided on the connecting base plate of the spray device.

[0083] like Figure 20 and Figure 21 As shown, optionally, the chilled water assembly includes: The first water inlet pipe 22 is used to connect bottled water; The second water inlet pipe 23 is used to connect to a direct drinking water pipe or a tap water pipe; Water outlet pipe 24, the water outlet pipe 24 is used for water outlet; The three-way pipe 25 is connected at its three ends to the first water inlet pipe 22, the second water inlet pipe 23 and the water outlet pipe 24 respectively. The switching device is a rubber stopper 26, a solenoid valve (not shown), or a rotary valve (not shown). The rubber stopper 26 is detachably installed at the port of the first water inlet pipe 22 or the second water inlet pipe 23. The solenoid valve is installed on the first water inlet pipe 22 and the second water inlet pipe 23. The rotary valve is connected to the three-way pipe 25 to rotate and switch the water inlet path.

[0084] By setting up independent first water inlet pipe 22 and second water inlet pipe 23, and using a three-way pipe 25 to merge the two water inlets into the same water outlet pipe 24, the coffee machine is compatible with three water sources: bottled water, direct drinking water, and tap water.

[0085] The switching device offers three different cost and operation options: the rubber stopper 26 is a purely mechanical manual sealing method, which is extremely low-cost and suitable for users who do not frequently switch water sources. When switching water sources is required, one inlet pipe needs to be blocked and then the other inlet pipe needs to be connected; the solenoid valve, combined with electronic control, can achieve one-button automatic switching. During installation, two water sources can be connected simultaneously, and subsequent switching does not require manual plugging and unplugging, enabling one-button switching and enhancing the intelligent experience; the knob valve directly blocks one of the water inlets by manual rotation, with a simple and reliable structure and no risk of losing the rubber stopper 26.

[0086] Compared to existing coffee machines that can only be fixed to a single water source, this solution fundamentally solves the problem of limited water source compatibility. Users can flexibly choose according to their actual home water supply conditions (such as only bottled water, direct drinking water supply, or tap water with filtration), avoiding the inability to use the equipment due to incompatible water sources or interruption of a water source, greatly improving the product's market adaptability and user convenience.

[0087] like Figure 21 As shown, optionally, when the switching device is a rubber plug 26, one end of the second water inlet pipe 23 is connected to a negative pressure valve 27, the negative pressure valve 27 includes a connection port 271, and the rubber plug 26 is adapted to be detachably connected to the connection port 271. When the switching device is the rubber stopper 26, the negative pressure valve 27 acts as a one-way shut-off and anti-backflow device in the water circuit. When the second inlet pipe 23 is not in use, external negative pressure or machine shutdown can prevent water from the first inlet pipe 22 from flowing back into the second inlet pipe 23, avoiding cross-contamination. Simultaneously, the connection port 271 on the negative pressure valve 27 is specifically designed to fit the rubber stopper 26. Users only need to insert the rubber stopper 26 into the connection port 271 to physically seal the water inlet, without the need for tools. This detachable connection structure ensures a complete seal of the water circuit when the second inlet pipe 23 is not in use, preventing air leakage that could cause the water pump 29 to fail. It also allows users to quickly remove the rubber stopper 26 to restore the flow when they need to switch to the second inlet pipe 23 in the future. The entire operation is simple and hygienic, effectively avoiding the cumbersome process and leakage risks associated with traditional water circuits that require disassembling pipes or adding valves.

[0088] When the switching device is a solenoid valve, the machine body is equipped with a controller and a control panel 28. The control panel 28 is equipped with a water source selection button, which is used to switch the water inlet status of the first water inlet pipe 22 and the second water inlet pipe 23. The controller is electrically connected to both the control panel 28 and the solenoid valve. When the switching device is a solenoid valve, the user only needs to press the corresponding water source selection button (such as "bottled water" or "drinking water / tap water") on the control panel 28. The controller then receives the command and drives the solenoid valve to automatically open the inlet pipe corresponding to the selected water source, while simultaneously closing the other pipe (or keeping it normally closed). The entire process requires no user contact with any water pipes, rubber stoppers 26, or knobs, avoiding errors or secondary contamination that may occur with manual operation. Compared to manual switching, the electronic switching offers rapid response, status memory, and remote control capabilities, significantly enhancing the product's technological appeal and user comfort. It is particularly suitable for integration into smart home systems, and especially for commercial or residential scenarios where water sources are frequently changed.

[0089] like Figure 21 As shown, the three-way pipe 25 includes a first inlet 251, a second inlet 252, and an outlet 253. The first inlet 251 is connected to the first inlet pipe 22, the second inlet 252 is connected to the second inlet pipe 23, and the outlet 253 is connected to the first inlet 251 and the second inlet 252. When the switching device is a rotary valve, the rotary valve rotates to block the first inlet 251 or the second inlet 252, thereby switching the water inlet paths of the first inlet pipe 22 and the second inlet pipe 23.

[0090] The "T" or "Y" shaped manifold structure of the three-way pipe 25 is extremely simple and compact, with a short internal flow channel and low resistance, which helps maintain stable water pressure. It directly merges two inlet pipes into one outlet 253, avoiding the complex design of using two independent outlet pipes 24, thereby reducing the number of pipe joints and making it easier to arrange in the small internal space of the coffee machine. At the same time, since the outlet 253 connects to both inlets, water can flow smoothly to the outlet pipe 24 regardless of which inlet is opened, eliminating pressure buildup caused by one-way blockage.

[0091] When the switching device is a rotary valve, the rotary valve and the three-way tube 25 form a three-way valve structure (three-way valves are existing technology, and their principles and internal structures will not be elaborated here). The user only needs to rotate the knob a certain angle (e.g., 90 degrees or 60 degrees, depending on the shape of the three-way tube 25), and the valve core will physically block one water inlet while simultaneously opening the other through the rotation of the valve plate. This switching method offers a clear tactile feedback and a precise feel, eliminating the coil burnout problem that can occur with solenoid valves. Even in a power outage environment or when the electronic components fail after prolonged use, the rotary valve can still function normally, ensuring the basic functionality of the coffee machine. Furthermore, the rotary valve's simple structure and low cost reduce the manufacturing cost of the coffee machine.

[0092] like Figure 21As shown, optionally, a water pump 29 is also included. The water pump 29 is connected to the water outlet pipe 24 and the water outlet 253 respectively to provide pumping power. The water pump 29 provides power so that when the water source is bottled water (unpressurized), the water pump 29 draws and lifts the water to the water outlet pipe 24; when the water source is drinking water or tap water (pressurized), the water pump 29 can act as a pressure boosting or stabilizing device to ensure a constant water flow rate. The water pump 29 is connected to the water outlet pipe 24 and the water outlet 253 respectively, which means that the water pump 29 is located after the T-connector 25 and before the final water outlet. Regardless of which water source is inlet, it is pressurized by the same water pump 29, ensuring the consistency of the water output under different water sources.

[0093] like Figure 22 As shown, optionally, the lower part of the machine body is provided with a water tank cavity 30 for holding bottled water. The front side of the machine body is provided with a rotating and opening plate 31. Opening the opening plate 31 facilitates the replacement of bottled water into the water tank cavity 30. The top of the water tank cavity 30 is provided with a concave limiting part 301, which restricts the installation position of the bottled water head. Replacing bottled water in traditional coffee machines often requires moving the entire machine out and lifting the water tank to align with the top interface, which is laborious and prone to spillage. This solution provides a water tank cavity 30 in the lower part of the machine body, and the front opening plate 31 can be rotated open. The concave limiting part 301 provides visual guidance; the user only needs to push the bottled water horizontally into the cavity until the bottled water head is limited within the concave limiting part 301 to complete the installation. When the opening plate 31 is closed, the appearance is neat and it also prevents dust or foreign objects from entering the water tank cavity 30.

[0094] like Figure 23 As shown, optionally, several support blocks 302 are symmetrically distributed on the left and right side walls of the water tank cavity 30. The support blocks 302 are suitable for placing partitions 303, which are used to place items. When the water source is drinking water or tap water, bottled water does not need to be placed in the water tank cavity 30. By symmetrically arranging multiple sets of support blocks 302 on the left and right side walls, users can freely choose the height to install one or more partitions 303. The partitions 303 adopt a mesh design to reduce weight and prevent water accumulation. These partitions 303 can be used to store small accessories such as coffee cups, coffee bean hoppers, cleaning brushes, and filters, giving the coffee machine itself a storage function. No additional shelves are needed, improving space utilization without increasing the overall size of the machine.

[0095] like Figure 20As shown, optionally, the machine body is provided with a mounting plate 32. The bottom of the mounting plate 32 is provided with a first mounting port, through which the first water inlet pipe 22 extends into the water tank cavity 30. The rear side of the mounting plate 32 is provided with a second mounting port, which is used to avoid the rubber stopper 26. The mounting plate 32 plays a role in centralized positioning and fixing of the pipeline. The first mounting port accurately guides the first water inlet pipe 22 to the precise position of extending into the water tank cavity 30, avoiding interference from other parts of the machine body and ensuring smooth connection when the bottled water is inserted. The connection port 271 of the negative pressure valve 27 is located in the second mounting port. When the user needs to manually remove or insert the rubber stopper 26, the finger can directly contact the rubber stopper 26 from the rear side without disassembling other parts. This avoidance structure greatly facilitates daily maintenance and switching operations. At the same time, the mounting plate 32 itself can serve as a fixing base plate for other water circuit components (such as solenoid valves and water pumps 29), improving the modularity of the whole machine assembly and facilitating production assembly and after-sales maintenance.

[0096] Optionally, the machine body is connected to a drawer body 17 (not shown). When the second water inlet pipe 23 is connected to a tap water pipe, the drawer body 17 is simultaneously connected to both the second water inlet pipe 23 and the tap water pipe, so that the tap water is filtered to a state suitable for direct drinking before being supplied to the second water inlet pipe 23. The drawer body 17 (e.g., a water purifier) ​​allows the coffee machine to safely and healthily connect to untreated tap water directly. Tap water may contain residual chlorine, heavy metals, suspended solids, bacteria, and other impurities, which can affect the taste and hygiene if used directly for brewing coffee. By adding the drawer body 17 (e.g., activated carbon + ultrafiltration or reverse osmosis), the tap water is treated to meet direct drinking standards before entering the second water inlet pipe 23, thereby ensuring the high quality of the water used by the coffee machine. The drawer body 17 can be integrated into the machine body or used as an external module.
