[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] Coffee machines typically include a grinding mechanism, a feed pipe, a brewing chamber, and a wastewater tray. The grinding mechanism grinds coffee beans into coffee powder, and the feed pipe delivers the coffee powder to the brewing chamber for brewing. During the brewing process, the brewing chamber generates a large amount of steam. This steam may rise back through the feed pipe and enter the grinding chamber, causing the coffee beans in the grinding mechanism to become damp. This affects the quality of the coffee powder and the grinding precision, and may even cause equipment malfunction.

[0038] Related technology discloses a soymilk maker, including a feeding container for receiving soybeans; a cooking container for brewing or cooking soymilk; and a valve structure disposed in a pipeline between the feeding container and the cooking container, wherein soybeans from the feeding container can enter the cooking container through the valve structure, and the valve structure is configured to close during the brewing or cooking of soymilk in the cooking container. However, the valve structure is located in the middle section of the pipeline between the feeding container and the cooking container, which can easily lead to the accumulation of moisture and soybean powder, causing localized contamination.

[0039] The following is combined Figures 1 to 24 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a cooking appliance is provided, which may specifically be a coffee machine.

[0041] The cooking appliance includes: a powder feeding pipe 1, a valve assembly, a partition 6, and a first sealing structure 13.

[0042] The valve assembly is located at the bottom end of the powder discharge pipe 1. The valve assembly includes a valve 4 and a drive structure 5. The valve 4, driven by the drive structure 5, has a closed position (closing the bottom opening) and an open position (opening the bottom opening). A partition 6 has a first opening for the bottom end of the powder discharge pipe 1 to pass through. The drive structure 5 is located on the partition 6, and the valve 4 is located below the partition 6. A first sealing structure 13 is located between the powder discharge pipe 1 and the first opening. Figure 5 and Figure 6 The first sealing structure 13 is provided with a scraper structure 1304, and the valve 4 has a working surface facing the partition 6, with the scraper structure 1304 in contact with the working surface.

[0043] In this embodiment, when the drive structure 5 drives the valve 4 to the open position, the bottom opening of the powder supply pipe 1 opens, allowing coffee powder to enter the area below the partition 6 for coffee making. When the drive structure 5 drives the valve 4 to the closed position, the bottom opening of the powder supply pipe 1 is closed, preventing steam generated during coffee making from rising into the powder supply pipe 1. This avoids steam contamination of the coffee powder or beans, thereby improving the quality of the coffee powder and ensuring the stability of the equipment, achieving the technical effects of improving coffee taste and extending equipment life. Furthermore, by placing the valve 4 at the bottom of the powder supply pipe 1, the accumulation of coffee powder and steam in the valve 4 is prevented. The powder supply pipe 1 and the first opening are sealed by the first sealing structure 13, preventing steam from flowing upwards through the gap between the powder supply pipe 1 and the first opening. A scraper structure 1304 is provided in the first sealing structure 13. When the valve 4 rotates under the drive of the drive structure 5, the scraper structure 1304 contacts the working surface of the valve 4, scraping away any coffee powder or dirt adhering to the valve 4, thus cleaning the valve 4.

[0044] In one embodiment, the first sealing structure 13 is provided with a first sealing rib 1301 at one end facing the valve 4, and the first sealing rib 1301 abuts against the working surface.

[0045] In this embodiment, the first sealing structure 13 is provided with a first sealing rib 1301 at one end facing the valve 4. The first sealing rib 1301 abuts against the working surface, which can ensure the seal between the valve 4 and the first sealing structure 13, and there is no gap between the valve 4 and the first sealing structure 13.

[0046] Specifically, the first sealing rib 1301 is interference-fitted with the working surface.

[0047] Specifically, the first sealing rib 1301 is circular.

[0048] In one embodiment, such as Figure 24 As shown, the first sealing structure 13 includes an inner ring surface 1302 and an outer ring surface 1303. The inner ring surface 1302 is interference-fitted with the powder discharge pipe 1, and the outer ring surface 1303 is interference-fitted with the first opening. The scraper structure 1304 is connected to the outer ring surface 1303 and is arc-shaped.

[0049] In this embodiment, the inner ring surface 1302 is interference-fitted with the powder discharge pipe 1, and the outer ring surface 1303 is interference-fitted with the first opening, which can ensure the sealing performance between the powder discharge pipe 1 and the first opening. The scraper structure 1304 is connected to the outer ring surface 1303, and the scraper structure 1304 and the first sealing structure 13 are an integral structure, which is simple in structure.

[0050] In one embodiment, the scraper structure 1304 is arc-shaped.

[0051] In this embodiment, since the scraper structure 1304 is arc-shaped, the contact area between it and the working surface of the valve 4 can be increased, thereby improving the scraping effect.

[0052] In one embodiment, such as Figure 1 and Figure 2 The cooking utensil includes a grinding mechanism 2 and a brewing vessel 3. The grinding mechanism 2 is connected to the powder supply pipe 1 and is located above the partition 6; the brewing vessel 3 has a powder inlet 301, which is directly opposite the bottom opening of the powder supply pipe 1 and is located below the partition 6.

[0053] When the drive structure 5 drives the valve 4 to the open position, the bottom opening of the coffee powder supply pipe 1 opens, allowing coffee powder produced by the grinding mechanism 2 or added manually by the user to enter the coffee powder inlet 301 of the brewer 3 through the supply pipe 1. During the brewing process, the drive structure 5 drives the valve 4 to the closed position, sealing the bottom opening of the supply pipe 1. This prevents steam generated during brewing from rising into the supply pipe 1, thus avoiding steam from rising into the grinding mechanism 2 and causing the coffee beans to become damp. This improves the quality of the coffee powder and ensures the stability of the equipment, achieving the technical effects of improving coffee taste and extending equipment life. Furthermore, by placing the valve 4 at the bottom of the supply pipe 1, it prevents the accumulation of coffee powder and steam in the valve 4.

[0054] The grinding mechanism 2 is located above the partition 6, and the brewer 3 is located below the partition 6. The partition 6 can prevent steam from flowing upward. The drive structure 5 is located on the partition 6 for easy fixing and installation. The valve 4 is located on the side of the partition 6 near the brewer 3, which can prevent the steam generated during the brewing process from flowing upward through the first opening of the partition 6. In addition, the valve 4 is located at the bottom of the coffee powder supply pipe 1, and coffee powder and steam do not easily accumulate on the valve 4.

[0055] In one specific embodiment, the cooking appliance includes a body 7, the space above the partition 6 forms a grinding chamber, the space below the partition 6 forms a brewing chamber, a wastewater tray 8 is provided below the brewing chamber, the partition 6 has the function of preventing water vapor from the brewing chamber and the wastewater tray 8 from entering the grinding chamber, and the brewing chamber and the grinding chamber are connected by a powder discharge pipe 1.

[0056] Specifically, such as Figure 11 As shown, a powder residue box 9 is provided on the wastewater tray 8. The wastewater tray 8 is located below the brewing chamber and the two are connected. After the brewing process of the brewer 3 is completed, the powder cake will fall into the powder residue box 9, and the wastewater generated by the self-cleaning of the brewer 3 will be discharged into the wastewater tray 8.

[0057] Specifically, the grinding chamber consists of a bean hopper 201, a bean hopper cover 202, and a grinding mechanism 2. The bean hopper cover 202 is placed on top of the bean hopper 201 and is sealed to the bean hopper 201 by a sealing ring 2021, which has the function of sealing the bean hopper 201 to prevent the coffee beans inside the bean hopper 201 from getting damp and to prevent foreign objects from entering the bean hopper 201. The grinding mechanism 2 is located at the bottom of the bean hopper 201 and can input the ground coffee powder into the powder delivery pipe 1.

[0058] Specifically, such as Figure 10 As shown, the middle section of the powder supply pipe 1 has a central opening 101, which is connected to the grinding mechanism 2.

[0059] In one embodiment, the drive structure 5 is located above the partition 6, the valve 4 includes a valve plate 401 and a connecting portion 402 provided on the valve plate 401, the partition 6 is provided with a second opening, and the connecting portion 402 passes through the second opening and connects to the drive structure 5.

[0060] In this embodiment, the drive structure 5 is positioned above the partition 6 to prevent the steam generated during the brewing process from contaminating the drive structure 5.

[0061] In one embodiment, such as Figure 10 As shown, the valve assembly includes a bushing 10, which is located outside the connecting portion 402 and is sealed to the second opening.

[0062] In this embodiment, the bushing 10 is located outside the connecting part 402 and is sealed to the second opening, which can prevent steam from entering the grinding chamber through the second opening and prevent steam from contaminating the drive structure 5.

[0063] In one embodiment, such as Figure 10 and Figure 15 , Figure 16 As shown, the bushing 10 includes a bushing body 1001 and a stepped structure 1002 disposed on the bushing body 1001. The bushing body 1001 passes through the second opening, and the stepped structure 1002 is supported on the partition 6.

[0064] In this embodiment, the bushing body 1001 passes through the second opening, and the stepped structure 1002 is supported on the partition 6. Therefore, the partition 6 can prevent the bushing 10 from falling down, and the installation method of the bushing 10 is simple.

[0065] Specifically, during installation, the bushing body 1001 is first passed through the second opening from top to bottom, and the stepped structure 1002 is supported on the partition 6. Then, the connecting part 402 of the valve 4 can pass through the inside of the bushing 10 from bottom to top and connect with the drive structure 5.

[0066] In one embodiment, the bushing body 1001 is positioned with the second opening by a positioning structure.

[0067] In this embodiment, the bushing body 1001 and the second opening are positioned by a positioning structure, so that the bushing 10 can be installed at a set angle.

[0068] In one embodiment, the positioning structure includes a first directional rib structure 1003 and a groove. The first directional rib structure 1003 is disposed on one of the outer wall of the bushing 10 and the side wall of the second opening, and the groove is disposed on the other of the outer wall of the bushing 10 and the side wall of the second opening. The shape of the first directional rib structure 1003 is adapted to the shape of the groove.

[0069] In this embodiment, the first directional rib structure 1003, in conjunction with the groove, allows the bushing 10 to be installed at a set angle.

[0070] Specifically, the first directional rib structure 1003 extends axially, and only one first directional rib structure 1003 can be provided. Correspondingly, there is only one groove, which ensures that the bushing 10 is installed at a set angle. Alternatively, when there are two first directional rib structures 1003, the widths of the two first directional rib structures 1003 can be different, and the grooves correspond one-to-one with the two first directional rib structures 1003, which ensures that the bushing 10 is installed at a set angle.

[0071] In this embodiment, there is one first directional rib structure 1003, which is disposed on the outer wall of the bushing 10, and the groove is disposed on the side wall of the second opening.

[0072] In one embodiment, the inner wall of the bushing body 1001 is provided with a slot 1004, which extends axially along the bushing body 1001. The bushing 10 also includes a countersunk structure 1005, which is located at the top of the slot 1004. The connecting part 402 is provided with a second directional rib structure 4021, which is adapted to pass through the slot 1004 and be supported on the countersunk structure 1005 by rotating the connecting part 402. The connecting part 402 is inserted into the drive structure 5. The valve 4 has an unlocked position. In the unlocked position, such as Figure 22 As shown, the second directional rib structure 4021 is aligned with the slot 1004.

[0073] In this embodiment, a slot 1004 is provided on the inner wall of the bushing body 1001, extending axially along the bushing body 1001. The connecting part 402 is provided with a second directional rib structure 4021. When installing the valve 4, the second directional rib structure 4021 on the connecting part 402 is aligned with the slot 1004 and installed from bottom to top. After the second directional rib structure 4021 passes through the slot 1004, the connecting part 402 is rotated so that the second directional rib... The strip structure 4021 is supported on the recessed platform structure 1005, and then the connecting part 402 is inserted into the drive structure 5. When the valve 4 rotates under the drive of the drive structure 5, the valve 4 will not fall down when the second directional rib structure 4021 is supported on the recessed platform structure 1005. When the valve 4 rotates to the unlocked position, the second directional rib structure 4021 is aligned with the slot 1004, and the valve 4 can be removed from the drive structure 5 for easy disassembly, assembly and cleaning.

[0074] The slot 1004 and the recessed platform structure 1005 allow the valve 4 to have an active angle and an unlocking angle. When the valve 4 rotates to the unlocking angle, the second directional rib structure 4021 aligns with the slot 1004, allowing the valve 4 to be removed from the drive structure 5 for easy disassembly, assembly, and cleaning. The valve 4's reciprocating rotation within the active angle allows it to close or open the bottom opening of the powder discharge pipe 1.

[0075] Specifically, the locking angle of valve 4 is set to 0°. When valve 4 is at 0°, such as... Figure 19 and Figure 21 Valve 4 closes the bottom opening of the powder supply pipe 1; the opening angle of valve 4 is set to 35°, and when valve 4 rotates 35°, the bottom opening of the powder supply pipe 1 is opened; Figure 22 As shown, when valve 4 is at 90°, the second directional rib structure 4021 aligns with the slot 1004, allowing valve 4 to be detached from the drive structure 5. In actual operation, to prevent excessive rotation of valve 4, the range of motion of valve 4 is defined as 0°-70°. Figure 19 and Figure 20 , Figure 20 Valve 4 is at 70°, thus allowing valve 4 to rotate between 0° and 70°.

[0076] Of course, in practical applications, the opening angle, moving angle, and unlocking angle can be set as needed. For example, the moving angle can be set to 0°-50°, or the opening angle can range from 35° to 145°, the moving angle from 0° to 180°, and the unlocking angle from 40° to 180°. This embodiment does not limit the locking angle, opening angle, moving angle, and unlocking angle of valve 4.

[0077] In one embodiment, the slot 1004 has at least two slots, and the width of at least one slot 1004 is different from the width of the other slots 1004. The second directional rib structure 4021 is provided correspondingly to the slot 1004.

[0078] In this embodiment, at least two slots 1004 are provided, and the width of at least one slot 1004 is different from the width of the other slots 1004. The second directional rib structure 4021 is provided corresponding to the slot 1004, which has a foolproof function and ensures that the valve 4 is installed correctly.

[0079] In one specific embodiment, the slot 1004 has two slots, and the two slots 1004 have different widths.

[0080] In one embodiment, the connecting part 402 is provided with a slot 4022, and the driving structure 5 includes a drive motor 501 and a rotating rod 502 connected to the output shaft of the drive motor 501. The rotating rod 502 includes a plug-in part 5021 adapted to the shape of the slot 4022, and the plug-in part 5021 is inserted into the slot 4022.

[0081] In this embodiment, the connecting part 402 is provided with a slot 4022, and the rotating rod 502 includes a plug part 5021 that is adapted to the shape of the slot 4022. The plug part 5021 is inserted into the slot 4022, which facilitates the connection between the rotating rod 502 and the valve 4, and can ensure that when the drive motor 501 is working, it can drive the valve 4 to rotate synchronously through the rotating rod 502.

[0082] In one embodiment, the shape of the insertion slot is non-circular, and the shape of the insertion portion 5021 on the rotating rod 502 is adapted to the shape of the insertion slot.

[0083] Specifically in one embodiment, such as Figure 16 As shown, the insertion slot is cross-shaped.

[0084] In one embodiment, such as Figure 10 , Figure 17 , Figure 18 , Figure 23 The partition 6 is provided with a support groove 601, and the valve plate 401 is provided with a stop rib 4011, which is adapted to move along the support groove 601.

[0085] In this embodiment, by providing a support groove 601 in the partition 6, the valve plate 401 is provided with a stop rib 4011. The stop rib 4011 is adapted to move along the support groove 601. The support groove 601 can guide and limit the rotation of the valve plate 401, ensuring that the valve plate 401 can close the bottom opening of the powder discharge pipe 1.

[0086] In one embodiment, the valve 4 has a locked position. In the locked position, the stop rib 4011 abuts against one end of the support groove 601, the valve 4 closes the bottom opening of the powder discharge pipe 1, and the second directional rib structure 4021 is supported on the sinking platform structure 1005. In the unlocked position, the second directional rib structure 4021 is aligned with the slot 1004.

[0087] In this embodiment, when in the locked position, the stop rib 4011 abuts against one end of the support groove 601, which can prevent the valve 4 from continuing to rotate. At this time, the valve 4 closes the bottom opening of the powder discharge pipe 1, and the valve 4 is in the closed position, which makes it convenient to set the rotation direction of the valve 4.

[0088] Specifically, the stop rib 4011 is provided at the edge of the valve 4. In this embodiment, the shape of the stop rib 4011 is not limited. It can be a rib that protrudes outward from the valve plate 401, or it can be formed by designing the outline shape of the valve plate 401.

[0089] In one embodiment, such as Figure 10 and Figure 18 The valve plate 401 is provided with a friction rib 4012 on the side opposite to the connecting part 402. The friction rib 4012 is arc-shaped and is located in the support groove 601.

[0090] In this embodiment, by setting friction ribs 4012, which are located inside the support groove 601, excessive frictional resistance can be avoided due to large-area contact between the valve plate 401 and the support groove 601.

[0091] Specifically, the friction rib 4012 and the support groove 601 are coaxially arranged.

[0092] In one embodiment, the cooking appliance further includes a first detection structure 11, which is capable of detecting the position of the valve 4.

[0093] In this embodiment, by setting the first detection structure 11, the position of valve 4 can be detected in real time, which facilitates precise control of the position of valve 4.

[0094] Specifically, the cooking appliance includes a controller, which is communicatively connected to the first detection structure 11 and the drive motor 501. The controller can control whether the drive motor 501 works and the direction of rotation when it works based on the position detected by the first detection structure 11.

[0095] In one embodiment, the first detection structure 11 includes a photoelectric sensor or a Hall sensor, and the first detection structure 11 is disposed on the side of the partition 6 away from the brewer 3.

[0096] In this embodiment, the first detection structure 11 includes a photoelectric sensor or a Hall sensor. The first detection structure 11 can detect the position of the valve 4 without contacting the valve 4. Furthermore, by placing the first detection structure 11 on the side of the partition 6 away from the brewer 3, steam can be prevented from damaging the first detection structure 11.

[0097] In one specific embodiment, the first detection structure 11 includes a Hall sensor, which is located on the partition 6 or at another position on the body 7. A first magnet 12 is provided on the drive rod. When the drive motor 501 drives the valve 4 to rotate through the drive rod, the position of the first magnet 12 rotates with it, and the distance between the first magnet 12 and the Hall sensor changes continuously. Therefore, the position of the valve 4 can be determined based on the electrical signal output by the Hall sensor.

[0098] In one specific embodiment, the drive rod is provided with a first mounting groove 5022, and the first magnet 12 is fixed in the first mounting groove 5022.

[0099] In one embodiment, the partition 6 has a first opening through which the bottom end of the powder discharge pipe 1 passes. The powder discharge pipe 1 is sealed to the first opening by a first sealing structure 13. The first sealing structure 13 has a scraper structure 1304. The valve 4 has a working surface facing the partition 6, and the scraper structure 1304 is in contact with the working surface.

[0100] In one embodiment, such as Figures 1 to 3 , Figure 5 , Figure 8 and Figure 9 The top of the powder discharge pipe 1 is provided with a sealing cover 14, which is designed to be openable and closable.

[0101] In this embodiment, by providing a sealing cap 14 at the top of the powder supply pipe 1, dust can be prevented from entering the inside of the powder supply pipe 1.

[0102] Specifically, such as Figure 9 As shown, a handle 1401 is provided on one side of the sealing cover 14 to facilitate the user to open or close the sealing cover 14.

[0103] In one embodiment, the cooking appliance further includes a second detection structure 15, which is capable of detecting the position of the sealing cap 14.

[0104] In this embodiment, the position of the sealing cap 14 can be detected in real time by setting the second detection structure 15.

[0105] In one embodiment, one end of the sealing cap 14 is hinged to the top of the powder-feeding pipe 1 via a rotating shaft. The rotating shaft or the sealing cap 14 is provided with a second magnet 16. The second detection structure 15 includes a Hall sensor provided on the powder-feeding pipe 1 or the body 7 of the cooking appliance.

[0106] In this embodiment, the rotating shaft or sealing cover 14 is provided with a second magnet 16, and the second detection structure 15 includes a Hall sensor provided on the powder discharge pipe 1 or the body 7 of the cooking appliance, which can determine the position of the sealing cover 14 based on the electrical signal output by the Hall sensor.

[0107] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
