Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] There are two main pressure relief methods in existing food processing machines. One method involves setting the pressure relief hole on the lid and installing a float valve at the hole. When the pressure in the pulping chamber is too high, or when pressure relief is needed after high-pressure cooking, the steam in the pulping chamber is released through the float valve to balance the external air pressure. However, the float valve directly discharges steam upwards, posing a risk of scalding the user and resulting in a poor user experience.

[0003] Another pressure relief method involves setting the pressure relief hole on the side wall of the cup. For example, a safe food processing machine disclosed in patent CN113842066B has a connecting hole on the peripheral wall of the cup that communicates with the pulping chamber. The connecting hole can allow water, air, and steam to enter the pulping chamber, and can even discharge the pressure inside the pulping chamber to the outside atmosphere through a connecting pipe. Another example is a food processing machine disclosed in patent CN113273907A, which uses a solenoid valve connected to a pipe above the residual water box to form a venting channel. This design avoids the problem of steam escaping directly upwards and causing burns to users. However, since the connecting hole is located on the side wall of the cup, during the mixing process of the food processor, the high-speed rotating blades create a strong mixing vortex inside the cup, causing the slurry to rise violently along the side wall of the cup, thus covering the connecting hole. Throughout the high-speed mixing process, the connecting hole is continuously blocked by the slurry, preventing effective venting and causing a sudden increase in pressure inside the cup. Moreover, even if the slurry carries slurry residue as it rises along the cup wall, the residue will remain in the connecting hole after the mixing process is completed, causing blockage and resulting in poor venting. Utility Model Content

[0004] This utility model provides a food processing machine that, in addition to solving the problem of user burns caused by the cup lid venting in existing food processing machines, further solves the technical problem of poor venting caused by the pressure relief port being covered by the stirring vortex and unable to effectively vent, or being blocked by pulp residue.

[0005] The technical solution adopted in this utility model is as follows: This utility model provides a food processing machine, including a main unit, a waste water box, a cup body installed on the main unit, a cup lid, and a pressure relief pipe. The cup lid covers the cup body to form a pulping chamber. The pulping chamber has a drain port, and a pulp discharge valve is provided at the drain port. The waste water box is located below the pulp discharge valve. The cup lid has a pressure relief port communicating with the pulping chamber. One end of the pressure relief pipe is connected to the pressure relief port, and the other end extends to communicate with the waste water box. A pressure relief valve is provided on the pressure relief pipe, and the pressure relief valve is installed inside the main unit.

[0006] This invention features a pressure relief port on the cup lid, connected to the pulping chamber. Located on the lid rather than the side wall of the cup body, this design reduces the risk of the pressure relief port being obstructed by the stirring vortex and also lowers the probability of slurry-laden residue clogging it. When pressure relief is needed in the pulping chamber, continuous and effective venting is achieved without obstruction, resulting in more continuous and smooth pressure relief and improved efficiency. Furthermore, a pressure relief pipeline, with one end connected to the pressure relief port and the other extending to the residual water box, safely guides the high-pressure steam generated in the pulping chamber during processing to the residual water box. This isolates the pressure relief path from the user, effectively preventing the risk of burns from close contact with the user by high-temperature steam and enhancing user safety.

[0007] In a preferred embodiment, the cup lid is detachably installed on the cup body, the pressure relief pipeline includes a first pipeline disposed on the cup lid and a second pipeline disposed on the main unit, the pressure relief valve is disposed on the second pipeline, one end of the first pipeline is connected to the pressure relief port and the other end is connected to an upper coupling connector, the main unit is provided with a lower coupling connector that is coupled and communicates with the upper coupling connector, and the lower coupling connector is connected to the second pipeline.

[0008] By detachably installing the lid onto the cup body, users can easily disassemble and clean the lid, ensuring cleanliness and hygiene, and facilitating material feeding. An independent first pipeline with a coupling connector is incorporated into the lid, allowing for easy cleaning while maintaining the integrity and seal of the pressure relief pipeline through the upper and lower coupling connectors. This effectively discharges high-pressure steam from the pulping chamber to the residual water box, avoiding the risk of burns from direct leakage of high-temperature steam from the lid. It also ensures reliable continuity of the pressure relief pipeline after repeated disassembly and reassembly, balancing sustained and smooth pressure relief.

[0009] In a preferred embodiment, the food processing machine further includes a supply device and a supply pipeline connected to the supply device. The lower coupling connector includes a tee connector, which includes a first interface communicating with the upper coupling connector, a second interface communicating with the second pipeline, and a third interface communicating with the supply pipeline.

[0010] By incorporating a supply device to supply water or gas to the pulping chamber, the food processing machine achieves intelligence and multi-functionality. Water is used for pulping or cleaning, while gas is supplied for drying. The lower coupling connector, including a T-junction, integrates the previously separate supply pipeline and the second pipeline in the pressure relief channel into a single interface, achieving a compact integration of the pressure relief path and the media supply path within the main unit. Simultaneously, when the supply device supplies cleaning water to the cup, the water enters the cup and, through the pressure relief port, creates a reverse flushing effect, further preventing blockage of the pressure relief port and subsequent poor venting. Furthermore, the elimination of a separate supply port on the cup simplifies the cup's manufacturing process, improves the sealing of the pulping chamber, and facilitates pressure pulping. It also avoids the leakage risks and structural complexity that can result from multiple openings and dispersed pipelines.

[0011] In a preferred embodiment, the lower coupling connector further includes a coupling tube fitted onto the host, one end of the coupling tube being coupled to the upper coupling connector, and the other end of the coupling tube being connected to the first interface of the tee connector.

[0012] By including a tee connector and a separate coupling pipe in the lower coupling connector, and using an independent coupling pipe to transition between the first interface of the upper coupling connector and the tee connector, the length, shape and end structure of the coupling pipe can be flexibly designed according to the specific installation position and size of the upper coupling connector and the tee connector. This effectively compensates for the installation deviation or size mismatch that may occur due to the structural limitations of the upper coupling connector and the tee connector themselves when directly coupling.

[0013] In a preferred embodiment, the food processing machine further includes a supply device and a supply coupling connector connected to the supply device. The upper coupling connector includes a tee pipe, which includes a first connecting pipe coupled to the lower coupling connector, a second connecting pipe connected to the pressure relief port, and a third connecting pipe connected to the supply coupling connector.

[0014] By including a tee pipe in the upper coupling connector, the medium supply path and pressure relief path of the supply device are compactly integrated on the cup lid. The medium can converge at the pressure relief port to enter the pulping chamber, eliminating the need for additional supply ports on the cup body, simplifying the cup body manufacturing process, and facilitating pressure pulping. This avoids the leakage risks and structural complexity that may result from multiple openings and dispersed pipelines. Simultaneously, when the supply device supplies cleaning water to the cup body, the cleaning water enters the cup body and passes through the pressure relief port to create a reverse flushing effect, further preventing the pressure relief port from becoming blocked and causing poor venting.

[0015] In a preferred embodiment, the host is provided with a mounting component that integrates the supply coupling connector and the lower coupling connector into one unit.

[0016] By setting up mounting components, the two key connecting components, the supply coupling connector and the lower coupling connector, can be integrated into the same structure. This reduces the space and fixing structure required for their independent installation, simplifies the assembly process, and ensures the accuracy of their relative positions through integrated installation. This makes the internal layout of the main unit more compact and orderly, thereby improving the stability and assembly efficiency of the overall structure and providing convenience for subsequent maintenance and repair.

[0017] In a preferred embodiment, a supply port is provided on the side wall of the cup body, and the food processing machine further includes a supply device and a supply pipeline connected to the supply device, the supply pipeline being in communication with the supply port.

[0018] By opening a supply port on the side wall of the cup, the path for the supply device to supply the medium to the pulping chamber is independent. The exhaust path of the cup and the medium supply path do not interfere with or affect each other, achieving the effect of supplying the medium while venting. For example, in the drying stage, hot gas is supplied to the cup by the supply device while water vapor is discharged by the pressure relief port, achieving the purpose of rapid drying.

[0019] In a preferred embodiment, the host is further equipped with a supply device and a supply pipeline connecting the supply device to the pulping chamber, wherein a pressure sensor is provided on the supply pipeline to detect the pressure inside the pulping chamber.

[0020] A pressure sensor is installed on the supply pipeline to detect the pressure inside the pulping chamber. The pressure in the pulping chamber can be directly monitored using the supply pipeline without the need for an additional independent pressure detection pipeline. This simplifies the overall structural layout and allows for real-time and accurate acquisition of pressure information inside the pulping chamber. This facilitates precise control of the heating, stirring, and media supply operations of the food processing machine based on pressure changes, enabling intelligent control of the food processing machine.

[0021] In a preferred embodiment, the cup lid is fixedly disposed above the cup body, and the cup lid has a through-hole for feeding, and a feeding cover is closed at the feeding hole.

[0022] By fixing the cup lid to the top of the cup body, the pressure relief pipeline does not need to be segmented or have a complex coupling structure, thus simplifying the overall structure of the machine. The feeding port allows users to feed materials without opening the lid and add materials mid-process, making operation convenient.

[0023] In a preferred embodiment, the cup lid is rotatably connected to the main unit via a pivot, and the pressure relief pipe passes along one side of the pivot to communicate with the pressure relief port.

[0024] The cup lid is rotatably connected to the main unit via a pivot, enabling it to be flipped open and closed. This simple operation ensures the lid will not be lost or misplaced. The pressure relief pipe runs along one side of the pivot to connect with the pressure relief port. This allows for efficient use of the space around the pivot, preventing excessive stretching or compression of the pipe due to the lid's flipping, reducing the risk of wear and breakage. This not only ensures a smooth and stable pressure relief path but also makes the overall structure more compact and orderly. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] like Figure 1 As shown, in one embodiment, this utility model provides a food processing machine, including a main unit 10, a water collection box 13, a cup body 11 installed on the main unit 10, a cup lid 12, and a pressure relief pipe 20. The cup lid 12 covers the cup body 11 to form a pulping chamber. The pulping chamber has a drain outlet, and a drain valve 14 is provided at the drain outlet. Figure 2As shown, the residual water box 13 and the receiving cup 16 are located below the discharge valve, and the cup cover 12 is provided with a pressure relief port 121 communicating with the pulping chamber. Figure 1-4 As shown, one end of the pressure relief pipe 20 is connected to the pressure relief port 121, and the other end extends to connect to the residual water box 13. A pressure relief valve 15 is installed on the pressure relief pipe 20, and the pressure relief valve 15 is installed inside the main unit 10.

[0033] This invention features a pressure relief port on the cup lid 12 that communicates with the pulping chamber. The pressure relief port is located on the lid 12 rather than on the side wall of the cup body 11. This not only reduces the risk of the pressure relief port being covered by the stirring vortex but also reduces the probability of the slurry carrying sludge and clogging the pressure relief port. When pressure relief is needed in the pulping chamber, continuous and effective venting is achieved without obstruction, resulting in more continuous and smooth pressure relief and improved efficiency. A pressure relief pipe 20 is installed, with one end connected to the pressure relief port and the other end extending to the residual water box 13. The pressure relief port and pipe 20 safely guide the high-pressure steam generated in the pulping chamber during processing away from the residual water box 13, isolating the pressure relief path from the user. This effectively avoids the risk of burns caused by high-temperature steam coming into close contact with the user, thus improving safety.

[0034] It is understood that the specific structure of the pressure relief pipe 20 in this utility model is adapted to the fitting method between the cup lid 12 and the cup body 11, and this utility model does not limit the specific structure of the pressure relief pipe 20. For example: Implementation Example 1, such as Figure 1-4 As shown, the cup lid 12 is detachably installed on the cup body 11. The pressure relief pipeline 20 includes a first pipeline 21 provided on the cup lid 12 and a second pipeline 22 provided on the main unit 10. The pressure relief valve 15 is provided on the second pipeline 22. One end of the first pipeline 21 is connected to the pressure relief port and the other end is connected to the upper coupling connector 30. The main unit 10 is provided with a lower coupling connector 40 that is coupled and connected to the upper coupling connector 30. The lower coupling connector 40 is connected to the second pipeline 22.

[0035] By detachably installing the cup lid 12 onto the cup body 11, users can easily disassemble and clean the cup lid 12, ensuring cleanliness and hygiene, and facilitating the feeding operation. By providing an independent first pipeline 21 with an upper coupling connector 30 on the cup lid 12, the cup lid 12 can be disassembled for cleaning while maintaining the complete connection and seal of the pressure relief pipeline through the upper coupling connector 30 and lower coupling connector 40. This effectively discharges the high-pressure steam from the pulping chamber to the residual water box 13, avoiding the risk of burns from direct leakage of high-temperature steam from the cup lid 12, and ensuring that the pressure relief pipeline 20 remains reliably connected after repeated disassembly and reassembly, thus balancing the durability and smoothness of pressure relief.

[0036] Preferably, in this embodiment, the food processing machine further includes a supply device 50 and a supply pipeline 51 connected to the supply device 50. The lower coupling connector 40 includes a tee connector 41, which includes a first interface communicating with the upper coupling connector 30, a second interface communicating with the second pipeline 22, and a third interface communicating with the supply pipeline 51. More preferably, the lower coupling connector 40 further includes a coupling pipe installed in the main unit 10, one end of which is coupled to the upper coupling connector 30, and the other end of which is connected to the first interface of the tee connector 41.

[0037] Specifically, in this embodiment, the supply device 50 is a water tank, used to supply water to the pulping chamber for pulping or to supply water for cleaning the cup 11. In practice, the supply device 50 can also be an air pump, used to inflate the pulping chamber to dry the cup 11.

[0038] By setting up a supply device 50 to supply water or gas to the pulping chamber, the food processing machine can be made intelligent and multifunctional by using water for pulping or cleaning or supplying gas for drying. The lower coupling connector 40 includes a three-way connector 41, which integrates the originally independent supply pipeline 51 and the second pipeline 22 in the pressure relief channel into the same interface for delivery, thus compactly integrating the pressure relief path and the medium supply path into the main unit 10. At the same time, when the supply device 50 can supply cleaning water to the cup body 11, the cleaning water will form a reverse flushing effect through the pressure relief port when entering the cup body 11, thereby further preventing the pressure relief port from being blocked and causing poor exhaust. Moreover, there is no need to set up a separate supply port in the cup body 11, which simplifies the processing technology of the cup body 11, improves the sealing of the pulping chamber, and facilitates pressure pulping. At the same time, it avoids the leakage risks and structural complexity that may be caused by multiple openings and dispersed pipelines.

[0039] By including a tee connector 41 and a separate coupling pipe in the lower coupling connector 40, and using an independent coupling pipe to transition between the first interfaces of the upper coupling connector 30 and the tee connector 41, the length, shape, and end structures of the coupling pipe can be flexibly designed according to the specific installation position and size of the upper coupling connector 30 and the tee connector 41. This effectively compensates for installation deviations or dimensional mismatches that may occur due to the structural limitations of the upper coupling connector 30 and the tee connector 41 when directly coupling. Of course, in other embodiments of this invention, the coupling pipe can be omitted, and the first interface of the tee connector 41 can be directly coupled to the upper coupling connector 30, reducing the amount of piping required.

[0040] Implementation Example 2, such as Figure 5As shown, unlike Implementation Example 1, in this implementation example, the food processing machine also includes a supply device 50 and a supply coupling connector 52 connected to the supply device 50. The upper coupling connector includes a three-way pipe 31, which includes a first connecting pipe coupled to the lower coupling connector 40, a second connecting pipe connected to the pressure relief port 121, and a third connecting pipe connected to the supply coupling connector 52.

[0041] By using the upper coupling connector, including the tee pipe 31, the medium supply path and pressure relief path of the supply device 50 are compactly integrated on the cup cover 12. The medium can converge at the pressure relief port to enter the pulping chamber, eliminating the need for an additional supply port on the cup body 11, simplifying the manufacturing process of the cup body 11, and facilitating pressure pulping. This avoids the leakage risks and structural complexity that may result from multiple openings and dispersed pipelines. Simultaneously, when the supply device 50 supplies cleaning water to the cup body 11, the cleaning water enters the cup body 11 and passes through the pressure relief port to create a backwashing effect, further preventing the pressure relief port from becoming blocked and causing poor venting.

[0042] Preferably, the host 10 is provided with a mounting component that integrates the supply coupling connector 52 and the lower coupling connector 40 into one unit.

[0043] By setting up mounting components, the two key connecting components, supply coupling connector 52 and lower coupling connector 40, can be integrated into the same structure. This reduces the space and fixing structure required for their independent installation, simplifies the assembly process, and ensures the accuracy of their relative positions through integrated installation. This makes the internal layout of the main unit 10 more compact and orderly, thereby improving the stability and assembly efficiency of the overall structure and providing convenience for subsequent maintenance and repair.

[0044] Implementation Example 3, such as Figure 6 As shown, unlike Implementation Example 1, in this implementation example, the side wall of the cup body 11 has a supply port 111, and the food processing machine also includes a supply device 50 and a supply pipe 51 connected to the supply device 50, with the supply pipe 51 connected to the supply port.

[0045] By opening a supply port on the side wall of the cup body 11, the path of the supply device 50 to supply the medium to the pulping chamber is independent. The exhaust path of the cup body 11 and the medium supply path do not interfere with or affect each other, thus achieving the effect of supplying the medium while venting the exhaust. For example, in the drying stage, hot gas is supplied to the cup body 11 by the supply device 50 while water vapor is discharged through the pressure relief port to achieve the purpose of rapid drying.

[0046] In this embodiment, a pressure sensor 60 is installed on the pressure relief line 20 to directly detect the pressure in the pulping chamber.

[0047] Of course, preferably, a pressure sensor can also be installed on the supply line 51 to detect the pressure inside the pulping chamber.

[0048] A pressure sensor is installed on the supply line 51 to detect the pressure inside the pulping chamber. The pressure inside the pulping chamber can be directly monitored using the passage of the supply line 51 without the need for an additional independent pressure detection line. This simplifies the overall structural layout and allows for real-time and accurate acquisition of pressure information inside the pulping chamber. It facilitates precise control of the heating, stirring, and media supply operations of the food processing machine based on pressure changes, thereby achieving intelligent control of the food processing machine.

[0049] In Implementation Example 4, unlike Implementation Example 1, the cup lid 12 is fixedly positioned above the cup body 11, and a feeding port is provided through the cup lid 12, with a feeding cover covering the feeding port. This configuration eliminates the need for segmentation and complex coupling structures in the pressure relief pipeline 20, thus simplifying the overall machine structure. The feeding port also allows users to easily add materials without opening the lid and to add materials mid-process, making operation convenient.

[0050] In Implementation Example 5, unlike Implementation Example 1, the cup lid 12 is rotatably connected to the host 10 via a rotating shaft, and the pressure relief pipe 20 passes through one side (front or rear) of the rotating shaft to communicate with the pressure relief port.

[0051] The cup lid 12 is rotatably connected to the main unit 10 via a pivot, enabling it to be flipped open and closed. This simple operation ensures the lid 12 will not be lost or misaligned. The pressure relief pipe 20 is routed along one side of the pivot to connect with the pressure relief port. This allows for efficient use of the space around the pivot, preventing excessive stretching or compression of the pipe due to the lid 12 flipping, reducing the risk of pipe wear and breakage. This not only ensures a smooth and stable pressure relief path but also makes the overall structure more compact and orderly.
