The coffee maker includes a water receiving container with an outlet connected to the wastewater outlet. This utility model integrates a water purifier and a coffee maker into one machine, where the water purification component is a water purifier and the coffee maker is a coffee maker. The water purification component typically includes a filtration module such as an RO (Reverse Osmosis) membrane. The filtration module filters tap water to produce purified water. During the filtration process, concentrated water, i.e., wastewater, is usually produced. Therefore, the filtration module usually has a wastewater outlet connected to a wastewater discharge channel to discharge the wastewater to a floor drain. Based on this, the coffee-making component provided by this utility model, by setting a water outlet on the water receiving container and connecting the water outlet to the wastewater outlet of the filter module, allows the wastewater in the water receiving container to flow sequentially through the water outlet, the wastewater outlet of the filter module, and the aforementioned wastewater discharge channel to the floor drain during the water purification component's wastewater production process, thereby realizing the wastewater discharge process of the water receiving container.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Example: like Figure 1 , Figure 2 and Figure 3As shown, the coffee maker provided in this embodiment includes a water purification component 1 and a coffee making component 2; the water purification component 1 includes a filter module 10, the filter module 10 is provided with a wastewater outlet, the filter module 10 is used to filter water and discharge the wastewater generated during the filtration process through the wastewater outlet; the coffee making component 2 includes a water receiving container 20, the water receiving container 20 is provided with a water outlet, and the water outlet is connected to the wastewater outlet.

[0023] The coffee maker provided in this embodiment is a machine that integrates a water purifier and a coffee maker into one unit, wherein the water purification component 1 is a water purifier, and the coffee making component 2 is a coffee maker. Figure 3 As shown, the water purification component 1 typically includes a filtration module 10 such as an RO (Reverse Osmosis) membrane. The filtration module 10 is used to filter tap water to produce purified water. During the filtration process, concentrated water, i.e. wastewater, is usually generated. Therefore, the filtration module 10 is usually provided with a wastewater outlet and a wastewater discharge channel 14 is connected to the wastewater outlet to discharge the wastewater to the floor drain 5.

[0024] Based on this, the coffee-making component 2 provided in this embodiment, by setting a water outlet on the water receiving container 20 and connecting the water outlet to the wastewater outlet of the filter module 10, allows the wastewater in the water receiving container 20 to flow sequentially through the water outlet, the wastewater outlet of the filter module 10, and the aforementioned wastewater discharge channel 14 to the floor drain 5 during the water purification component 1's water purification process, thereby realizing the wastewater discharge process of the water receiving container 20. Since the water purification component 1 has a high daily usage rate, the water receiving container 20 can also be periodically drained through the periodic water production of the water purification component 1, eliminating the need for manual periodic emptying of the wastewater in the water receiving container 20, greatly improving the convenience of the wastewater discharge operation of the water receiving container 20.

[0025] Compared with the prior art, the coffee purifier provided in this embodiment connects the water receiving container 20 of the coffee making component 2 with the wastewater outlet of the filter module 10 in the water purification component 1. This allows the wastewater in the water receiving container 20 of the coffee making component 2 to be discharged together through the wastewater discharge channel 14 of the water purification component 1 during the process of preparing purified water. This achieves regular drainage of the water receiving container 20, eliminating the need to manually empty the water in the water receiving container 20 periodically, thus improving the ease of operation.

[0026] To ensure the effectiveness of water purification, such as Figure 3 As shown, a pre-filter 11 can also be provided between the filtration module 10 of the water purification component 1 and the tap water source 3. The pre-filter 11 is used to perform preliminary filtration of the tap water. The pre-filter 11 can be made of activated carbon.

[0027] Furthermore, the water purification component 1 may also include an inlet valve 12 and a booster pump 13, with the tap water source 3, pre-filter 11, inlet valve 12, booster pump 13 and filter module 10 connected in sequence. The booster pump 13 is used to pump the water that has been pre-filtered by the pre-filter 11 to the filter module 10 when the inlet valve 12 is opened.

[0028] like Figure 3 As shown, the water outlet and the wastewater outlet are connected by a drainage pipe 200. A water suction component 4 is installed on the drainage pipe 200. The water suction component 4 is used to draw the liquid in the water receiving container 20 into the drainage pipe 200 when the filter module 10 filters the water.

[0029] The water absorption component 4 can be activated when the water purification component 1 turns on the water production or rinsing function. During the water production and rinsing process, the water purification component 1 needs to use the filter module 10 to filter the tap water to produce purified water. Therefore, the water absorption component 4 can be used to remove the wastewater in the water receiving container 20 during the wastewater discharge process of the water purification component 1. Compared with the process of opening a water outlet at the bottom of the water receiving container 20 and relying on gravity to achieve drainage, the water absorption component 4 can improve the wastewater discharge efficiency in the water receiving container 20.

[0030] Furthermore, such as Figure 3 As shown, the wastewater outlet of the water purification component 1 can be connected to a wastewater discharge channel 14, and a concentrated water valve 15 is provided on the wastewater discharge channel 14; the outlet of the water receiving container 20 is connected to the wastewater discharge channel 14 on the side away from the wastewater outlet through the drain pipe 200, so that the wastewater discharge channel 14 and the drain pipe 200 are connected between the wastewater outlet and the outlet.

[0031] The concentrated water valve 15 can also be linked with the water suction component 4. When the concentrated water valve 15 is opened, the water suction component 4 is activated, so that the water suction component 4 can automatically draw the wastewater in the water receiving container 20 to the wastewater discharge channel 14 during the water purification process, and then discharge it through the floor drain 5.

[0032] The water suction component 4 can be a water pump or a siphon, or other device capable of pumping water. To simplify the structure of the coffee maker and reduce its manufacturing cost, this embodiment preferably uses a siphon as the water suction component 4. The siphon end of the siphon is connected to the outlet of the water receiving container 20. The siphon is used to achieve automatic suction of liquid or gas by utilizing the principle of pressure difference.

[0033] It can be seen that when the water suction component 4 is a siphon, the siphon function of the siphon can be used to automatically discharge the wastewater in the water receiving container 20 into the floor drain 5.

[0034] It should be noted that the siphon achieves its siphon function using the Venturi principle. The Venturi principle is as follows: In a fluid system, when fluid flows through a narrow section (such as the throat of a Venturi tube), the flow velocity increases and the pressure decreases; conversely, when fluid flows through a wide section, the flow velocity decreases and the pressure increases.

[0035] Based on this, such as Figure 4 As shown, the water absorption assembly 4 in this embodiment has a first cavity 40 and a second cavity 41 inside; the first cavity 40 has a wastewater inlet 400 and a total outlet 401 on both sides, the wastewater inlet 400 is connected to the wastewater outlet, and the first cavity 40 has a variable diameter part 402 located between the wastewater inlet 400 and the total outlet 401. The variable diameter part 402 is used to reduce the radial cross-sectional area of ​​the first cavity 40 so that the radial cross-sectional area of ​​the first cavity 40 at the variable diameter part 402 is minimized; the second cavity 41 is connected to the first cavity 40, and the second cavity 41 has a water inlet 410, which is connected to the water outlet.

[0036] Among them, the wastewater inlet 400 is connected to the wastewater discharge channel 14 on the side of the concentrated water valve 15 away from the wastewater outlet, the total outlet 401 is connected to the floor drain 5, and the water inlet 410 on the second cavity 41 is the siphon end of the aforementioned siphon, which is connected to the water outlet of the water receiving container 20 through the drainage pipe 200.

[0037] Figure 4 The arrows shown indicate the flow direction of wastewater generated by the water purification component 1 and wastewater in the water receiving container 20 as they enter the water absorption component 4. When the water purification component 1 prepares purified water or performs rinsing, the wastewater such as concentrated water or rinsing water generated at the filter module 10 is discharged through the wastewater outlet and flows sequentially through the concentrated water valve 15 and the wastewater inlet 400 of the first cavity 40, and then enters the first cavity 40. When the wastewater flows to the diameter change section 402 of the first cavity 40, the radial cross-sectional area of ​​the first cavity 40 becomes smaller at this point. Therefore, under the action of the Venturi principle, the flow velocity of the wastewater increases at the diameter change section 402, thereby generating negative pressure in the first cavity 40. Since the first cavity 40 is connected to the second cavity 41, negative pressure is also generated in the second cavity 41 at this time. After negative pressure is generated in the second cavity 41, the wastewater in the water receiving container 20 can be sucked in, so that the wastewater in the water receiving container 20 flows together with the wastewater discharged from the water purification component 1 to the total outlet 401, and then is discharged into the floor drain 5.

[0038] The variable diameter section 402 can be achieved by narrowing the first cavity 40, or by setting a fastener in the first cavity 40 and then making a small perforation in the fastener.

[0039] In addition, the second cavity 41 can be an annular cavity, in which case the second cavity 41 is arranged around the periphery of the first cavity 40, and the first cavity 40 and the second cavity 41 are connected by a through hole 43 opened in the side wall of the cavity.

[0040] To improve the drainage efficiency of the water absorption component 4 and facilitate its connection with the floor drain 5, such as Figure 4 As shown, the water absorption assembly 4 may also include a housing 44 fixed below the first cavity 40. The housing 44 has openings at the top and bottom, and the radial cross-sectional area of ​​the housing 44 is larger than the radial cross-sectional area of ​​the first cavity 40. The total outlet 401 of the first cavity 40 extends into the housing 44 through the opening at the top of the housing 44. A threaded tube 45 is fixed and connected to the opening at the bottom of the housing 44. The threaded tube 45 is used to extend into the floor drain 5 and be threadedly connected to the internal thread at the floor drain 5, thereby realizing the connection between the water absorption assembly 4 and the floor drain 5.

[0041] like Figure 1 and Figure 2 As shown, the water purification component 1 is installed below or behind the coffee making component 2.

[0042] When the water purification component 1 is installed below or behind the coffee making component 2, it facilitates the replacement of the filter element of the filter module 10 of the water purification component 1. In addition, this arrangement also helps to shorten the drainage pipe 200, optimize the pipe layout, and effectively improve the integration and neatness of the coffee purifier.

[0043] In this embodiment, the water purification component 1 includes a purified water outlet, and the coffee making component 2 is provided with a water inlet, with the purified water outlet connected to the water inlet.

[0044] When the water purification outlet is connected to the water inlet, the purified water prepared by the water purification component 1 can be used to supply water to the coffee making component 2, eliminating the need for the user to manually add purified water to the coffee making component 2 and avoiding the need to frequently add water to the coffee making component 2 during use.

[0045] Furthermore, such as Figure 3 As shown, the coffee-making component 2 includes a water tank 21 with a water inlet located on the water tank 21. A high-level sensor and a low-level sensor are installed inside the water tank 21, both of which are connected to the water purification component 1. The water purification component 1 is used to start making water when the liquid level in the water tank 21 reaches the sensing position of the low-level sensor and to stop making water when the liquid level in the water tank 21 reaches the sensing position of the high-level sensor.

[0046] The water tank 21 is used to store the purified water supplied by the water purification component 1 to the coffee making component 2. When the coffee making component 2 needs to be used alone, it is not necessary to turn on the water purification component 1 at the same time, thereby improving the ease of use of the coffee making component 2.

[0047] Both the high-level and low-level sensors can be liquid level sensors. They can be connected to the control system of the water purification component 1. When the water level in the water tank 21 reaches the sensing position of the low-level sensor, the low-level sensor sends a low-level signal to the control system. When the control system receives the low-level signal, it controls the water purification component 1 to start and produce water, thereby replenishing the water tank 21. When the water level in the water tank 21 reaches the sensing position of the high-level sensor, the high-level sensor sends a high-level signal to the control system. When the control system receives the high-level signal, it controls the water purification component 1 to stop producing water, thereby preventing the water tank 21 from overflowing.

[0048] It can be seen that the high liquid level sensor and the low liquid level sensor can work with the water purification component 1 to actively supply water to the water tank 21, eliminating the need for the user to add water, thus effectively improving the ease of use of the coffee purifier.

[0049] Furthermore, such as Figure 3 As shown, the water purification component 1 may also include a post-filter 16 and an outlet valve 17. The filter module 10 is provided with a purified water outlet. The purified water outlet, the post-filter 16 and the water inlet on the water tank 21 are connected in sequence. The outlet valve 17 is set on the pipe between the post-filter 16 and the water tank 21.

[0050] The post-filter 16 is used to further filter the purified water produced by the filter module 10 to improve the purification level of the water. The outlet valve 17 is used to open and close to control the flow of the pipeline between the post-filter 16 and the water tank 21. The post-filter 16 may be made of activated carbon.

[0051] In this embodiment, as Figure 3 As shown, the coffee-making assembly 2 also includes a heating element 22, an extractor 23, and an outlet structure 24; the water inlet, heating element 22, and extractor 23 are connected in sequence. The heating element 22 is used to heat the purified water entering at the water inlet, and the extractor 23 is used to extract coffee liquid; the outlet structure 24 includes a coffee outlet, and the extractor 23 is connected to the coffee outlet, as shown. Figure 1 and Figure 2 As shown, the outlet structure 24 is located above the water receiving container 20, and the top of the water receiving container 20 is provided with a water inlet.

[0052] The heating element 22 is used to heat the purified water to facilitate coffee extraction, and the water inlet at the top of the water container 20 is used to collect the wastewater generated during the operation of the coffee making component 2.

[0053] Furthermore, such as Figure 3 and Figure 5As shown, the coffee-making assembly 2 may also include a flow meter 25, a vibration pump 26, a bean hopper 230, a grinder 231, and a waste bin 232; the vibration pump 26 is connected between the water inlet on the water tank 21 and the heating element 22, and the flow meter 25 is installed on the pipe between the water tank 21 and the vibration pump 26; the extractor 23 has a hot water inlet, a coffee inlet, and a waste bin outlet, the hot water inlet is connected to the heating element 22, the bean hopper 230, the grinder 231, and the coffee inlet of the extractor 23 are connected, and the waste bin outlet of the extractor 23 is connected to the waste bin 232.

[0054] When a user needs to make coffee, they can directly press the coffee making button on the coffee making component 2. At this time, the coffee making component 2 receives the coffee making signal, and firstly, the coffee beans in the bean hopper 230 flow into the grinder 231. The grinder 231 grinds the coffee beans into powder, and then flows into the extractor 23. The extractor 23 compresses and compacts the ground coffee powder, and then starts the vibration pump 26. With the cooperation of the flow meter 25, a certain amount of purified water is drawn from the water tank 21. The purified water is heated by the heating element 22 and then flows into the extractor 23 to extract the coffee. Finally, the extracted coffee liquid flows out through the coffee outlet of the outlet structure 24, and the extracted coffee grounds enter the grounds bin 232.

[0055] In practical applications, the coffee making component 2 can also have the function of taking only hot water. At this time, by pressing the water taking button on the coffee making component 2, the coffee making component 2 can receive the water taking signal and start only the vibration pump 26. Thus, the vibration pump 26, with the cooperation of the flow meter 25, draws a certain amount of clean water from the water tank 21 and then heats it into hot water through the heating element 22. The hot water then flows out through the coffee outlet of the outlet structure 24.

[0056] As can be seen, the coffee maker provided in this embodiment not only has water purification and coffee making functions, but also has the hot water dispensing function of a water dispenser, thus integrating the functions of a water purifier, a water dispenser, and a coffee maker into one unit.

[0057] To prevent the hot water and coffee from mixing flavors, such as Figure 3 and Figure 6 As shown, in this preferred embodiment, the coffee-making assembly 2 further includes a water distributor 27 disposed between the heating element 22 and the extractor 23; the outlet structure 24 further includes a hot water outlet. The water distributor 27 includes an inlet, a first outlet, and a second outlet. The inlet of the water distributor 27 is connected to the heating element 22, the first outlet is connected to the extractor 23, and the second outlet is connected to the hot water outlet.

[0058] The first outlet connects the heating element 22 and the extractor 23 to supply hot water to the extractor 23, ensuring the normal extraction process of coffee. The second outlet connects to the hot water outlet of the outlet structure 24, allowing the user to obtain hot water separately. It can be seen that the water distributor 27 separates the hot water outlet and the coffee outlet, making them independent and effectively preventing cross-contamination of coffee flavors with hot water, thus affecting the user experience.

[0059] When the coffee making component 2 also includes a water distributor 27, when the user wants to get hot water, he / she can directly press the water dispensing button on the coffee making component 2. At this time, the coffee making component 2 receives the water dispensing signal and starts the vibration pump 26. With the cooperation of the flow meter 25, the vibration pump 26 draws a certain amount of clean water from the water tank 21 and then heats it into hot water through the heating element 22. The hot water then flows out through the hot water outlet of the outlet structure 24.

[0060] like Figure 3 and Figure 7 As shown, the coffee-making component 2 may also include a steam rod and a milk container 28. The steam rod is installed at the hot water outlet, the milk container 28 is used to hold milk, and the steam rod is used to generate steam to heat or froth the milk in the milk container 28 to form milk foam.

[0061] To prevent interference with the hot water extraction process at the hot water outlet, the steam rod is detachably connected to the hot water outlet.

[0062] When the coffee maker 2 also includes a steam wand and a milk container 28, the coffee maker 2 also has the function of making milk foam and heating milk. For example... Figure 7 As shown, when a user needs to make milk foam or hot milk, they can first install the steam wand at the hot water outlet, and then press the milk foam making button or hot milk making button on the steam maker 2. The steam maker 2 then receives the signal and activates the vibration pump 26, which, with the assistance of the flow meter 25, draws a measured amount of purified water from the water tank 21. The purified water is heated into high-temperature steam by the heating element 22, and then the steam flows through the water distributor 27 to the hot water outlet, and then through the steam wand to heat the milk or froth it into fine foam. During milk foam making, the high-temperature steam emitted by the steam wand denatures the proteins in the milk and incorporates air, thus forming abundant milk foam.

[0063] Furthermore, the coffee maker 2 also has the function of making milk-based coffees such as lattes and cappuccinos. When making milk-based coffees, the coffee maker 2 can be divided into two steps.

[0064] Specifically, when a user wants to make milk coffee, they can first install the steam wand at the hot water outlet, and then press the milk coffee making button on the coffee making component 2. At this time, the coffee making component 2 will proceed to the first step of making coffee. That is, after receiving the signal to make milk coffee, the coffee making component 2 will first allow the coffee beans in the bean hopper 230 to flow into the grinder 231. The grinder 231 grinds the coffee beans into powder, and then the powder flows into the extractor 23. The extractor 23 compresses and compacts the ground coffee powder, and then starts the vibration pump 26. With the cooperation of the flow meter 25, a certain amount of purified water is drawn from the water tank 21. After being heated by the heating element 22, the purified water flows into the extractor 23 through the first outlet of the water distributor 27, thereby extracting the coffee. The extracted coffee liquid flows out through the coffee outlet of the outlet structure 24, while the coffee grounds enter the grounds bin 232.

[0065] Then, the coffee-making component 2 proceeds to the second step of making milk foam. At this time, the heating element 22 heats some of the purified water to form high-temperature steam. The high-temperature steam flows to the milk tank 28 through the second outlet of the water distributor 27 and the hot water outlet of the outlet structure 24. At the same time, the steam rod heats the milk in the milk tank 28 and froths it into fine milk foam. The user can make a latte or cappuccino by pouring the milk foam from the milk tank 28 into the prepared coffee liquid.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
