Description

Technical Field

[0001] This application relates to the field of small household appliance technology, and in particular to food processors. Background Technology

[0002] A food processor, such as a meat slicer or vegetable slicer, consists of a main body and a blade assembly. The main body includes a mounting cavity, a feed channel communicating with the mounting cavity, and a discharge port located at the bottom of the mounting cavity. The blade assembly is located inside the mounting cavity, below the feed channel. In use, food (such as meat or vegetables) is placed into the mounting cavity through the feed channel. The food is cut by the blade assembly below the feed channel, and the cut food exits from the discharge port at the bottom of the main body.

[0003] In the aforementioned food processors, because the blade assembly is located inside the mounting cavity, it needs to be disassembled for cleaning. After disassembly, the blades of the blade assembly are exposed, posing a safety hazard. It also requires the use of tools such as a cleaning brush, water gun, or scraper. Even after disassembly, cleaning is inconvenient. Summary of the Invention

[0004] The purpose of this application is to disclose a food processor. The blade assembly of the food processor is easy to clean and can avoid safety hazards.

[0005] This application discloses a food processor. The food processor includes a main body, a blade assembly, a door assembly, a water supply assembly, and an air intake device, wherein: the main body includes a mounting cavity and a discharge port located at the bottom of the mounting cavity; the blade assembly is mounted in the mounting cavity and located above the discharge port, and includes blades; the door assembly is assembled with the main body and includes a door for opening or closing the discharge port. The water supply assembly is assembled with the main body, and when the door is closed and the discharge port is closed, the mounting cavity forms at least a semi-closed cavity, and the water supply assembly supplies water to the mounting cavity to soak the blade assembly; the air intake device communicates with the mounting cavity, and the air intake device introduces gas into the water in the mounting cavity to generate bubbles that can collide with the blades.

[0006] As described above, since the blade assembly is immersed in the mounting cavity, air bubbles are continuously generated through the air intake device. These bubbles continuously collide with the blades, causing the residue adhering to the blades to detach and dissolve into the water, thus cleaning the blades. After cleaning, the hatch opens and water is discharged through the outlet, achieving automatic cleaning of the blade assembly. It is not necessary to disassemble the blade assembly for cleaning, nor is it necessary to use tools such as cleaning brushes, water guns, and slag scrapers. Cleaning is convenient. In addition, since the blade assembly is located in the mounting cavity during the cleaning process, and the mounting cavity is at least a semi-enclosed cavity, the blades are not exposed, and there is no safety hazard.

[0007] In some embodiments, the blade assembly includes two sub-blade assemblies, each sub-blade assembly including a blade shaft and a plurality of blades; the plurality of blades are spaced apart along the axial direction of the blade shaft; the axes of the two blade shafts are located in the same horizontal plane; the air intake device includes an air pump and an air intake component, the air intake component being located below the blade assembly.

[0008] As described above, since the axes of the two blade shafts are located on the same horizontal plane and the air inlet is located below the blade assembly, the air bubbles move upwards and then strike the blades on the blade shafts, resulting in a good cleaning effect on the blade assembly.

[0009] In some embodiments, the air intake component is assembled or integrally formed with the hatch, and the air intake component is provided with multiple air intake holes; the air intake component moves synchronously with the hatch, and when the hatch closes the discharge port, the air intake holes are located below the blade assembly.

[0010] As described above, since the air intake component is assembled with the hatch or integrally formed, when the hatch closes the discharge port, the air intake hole is located below the blade assembly. This not only facilitates material discharge, but also allows the air bubbles to move upwards from the discharge port, traveling a longer distance, which can better clean the blade assembly (for example, a greater impact force results in better cleaning, or a longer travel distance allows it to contact more parts of the blade and clean more parts, resulting in better cleaning). Finally, assembling the air intake component with the hatch or integrally forming it with the hatch assembly integrates the air intake component with the hatch assembly, which is beneficial for the layout of other components.

[0011] In some embodiments, the door is provided with a threaded sleeve; the food processor includes a door drive motor and a lead screw; the lead screw passes through the threaded sleeve and meshes with it; the door drive motor drives the lead screw to rotate, thereby opening or closing the discharge port of the door.

[0012] As described above, the door is opened or closed at the discharge port by a door drive assembly consisting of a door drive motor, a lead screw, and a lead sleeve. The door drive assembly occupies little space, and the opening or closing of the door is smoother and more convenient.

[0013] In some embodiments, the food processor includes a control board and a door drive device; the door drive device, including a door drive motor, is used to drive the door to open or close the outlet; the food processor also includes a first inductive switch; the first inductive switch generates a sensing signal when the door is fully closed at the outlet; the control board controls the door drive motor to stop working according to the sensing signal; and / or, the food processor includes a second inductive switch; the second inductive switch generates a sensing signal when the door is fully open at the outlet; the control board controls the door drive motor to stop working according to the sensing signal.

[0014] As described above, by setting the control panel and also setting at least one of the first and second inductive switches, the movement of the hatch can be automatically controlled.

[0015] In some embodiments, the air intake device includes an air pump and an air intake component, the air intake component being embedded in the hatch, and the space between the air intake component and the hatch forming an airflow channel; the airflow channel communicates with a plurality of air intake holes of the air intake component, and the hatch is provided with an air intake portion communicating with the airflow channel and the air pump. And / or, the top surface of the air intake component is not higher than the top surface of the hatch.

[0016] As described above, under the conditions of facilitating material discharge and allowing for a longer bubble travel distance, the sum of the thicknesses of the air inlet and the hatch is relatively small (less than the sum of their thicknesses; in particular, if the top surface of the air inlet is not higher than the top surface of the hatch, the sum of their thicknesses is at most the thickness of the hatch). This is equivalent to integrating two components into one, resulting in a simpler structure. It eliminates the need to consider the position of the air inlet and its impact on hatch movement, making it easier to implement.

[0017] In some embodiments, the hatch includes a boss and a groove around the boss; the air intake is annular; the air intake is located within the groove and the boss is located within the annulus of the air intake, so that the air intake is embedded in the hatch.

[0018] As described above, the boss is located inside the ring of the air intake component, and the air intake component is located inside the groove, making it easy to fit the air intake component into the hatch.

[0019] In some embodiments, the air inlet is assembled to the side wall of the mounting cavity and located at the lower part of the mounting cavity; or, the discharge port includes a discharge port side wall, and the air inlet is mounted to the discharge port side wall.

[0020] With the above configuration, regardless of whether the air inlet is installed on the side wall of the discharge port or at the bottom of the mounting cavity, the air bubble travels a greater distance, thus improving the cleaning effect of the blade assembly.

[0021] In some embodiments, the air intake includes an air intake surface facing the blade assembly, the air intake surface being covered with air intake holes.

[0022] As described above, with air inlets covering the surface of the air inlet, gas can be discharged from multiple points, generating bubbles in multiple locations. This results in a larger cleaning range and better cleaning of the blade assembly. When the air inlet is annular, the air inlets cover the entire ring. This allows for easy insertion of the air inlet into the door, providing an even larger cleaning range. Furthermore, this insertion method, where the protrusion occupies part of the air inlet's surface area, effectively reduces the number of air inlets compared to a surface covered with air inlets without protrusions. This allows for higher pressure of the discharged gas, resulting in greater impact force on the food on the blade and a better cleaning effect.

[0023] In some embodiments, the water supply assembly includes a water tank, a heating assembly, and a water pump; the heating assembly heats water from the water tank, and the water pump pumps hot water into the mounting cavity; or, the water pump supplies water to the heating assembly, and the hot water from the heating assembly flows into the mounting cavity.

[0024] As described above, by soaking the knife assembly in hot water, the hot water can dissolve food residue and grease, making it easier to clean the knife assembly and resulting in a better cleaning effect.

[0025] In some embodiments, the main body is provided with a water inlet, which communicates with the mounting cavity and is located at the top of the mounting cavity.

[0026] As described above, since the water inlet is located at the top of the mounting cavity, water flows down from top to bottom, resulting in better cleaning of the blade assembly. This is especially true when the water is hot; the cleaning effect is even better.

[0027] In some embodiments, the food processor includes a comb and a comb drive device, wherein the comb includes spaced-apart teeth; the comb drive device drives the comb to reciprocate between a first position and a second position, wherein the teeth rub against the friction element during the movement. In the first position, the teeth are positioned between two adjacent blades; in the second position, the teeth are at least partially disengaged from between two adjacent blades.

[0028] As described above, the comb teeth are driven by a comb tooth drive device to reciprocate between a first position and a second position. The comb teeth can peel food off the blades, thus cleaning the blades of the blade assembly. Combined with the water flow driven by the comb teeth, the cleaning effect on the blades is excellent. When the comb teeth are in the first position, they are positioned between two adjacent blades; when they are in the second position, they are disengaged from between two adjacent blades. Therefore, the stroke of the comb teeth is longer, resulting in a more thorough cleaning.

[0029] In some embodiments, the food processor includes a friction element that frictionally contacts the comb teeth, the comb teeth rubbing against the friction element during reciprocating motion.

[0030] As described above, the blade assembly is immersed in the mounting cavity, and the blade comb drive device drives the blade comb to reciprocate between a first position and a second position. During this movement, the comb teeth rub against the friction element, which peels away food residue adhering to the comb teeth, achieving automatic cleaning. Cleaning the blade comb is convenient; for example, it is easy to clean without removing it from the mounting cavity. Furthermore, the reciprocating motion of the comb teeth allows for repeated scrubbing against the friction element, resulting in thorough cleaning. Additionally, when the comb teeth are in the first position, rotating the blade assembly moves the water, and the interaction between the blade assembly, the comb teeth, and the moving water cleans the blade assembly (especially the blade).

[0031] In some embodiments, the food processor further includes a scraper and a scraper drive device, the scraper being located within the mounting cavity; the scraper drive device is connected to the scraper and drives the scraper to reciprocate along the inner wall of the mounting cavity to scrape the inner wall.

[0032] As described above, the wall-scraping drive device drives the wall-scraping component to scrape the inner wall of the mounting cavity, making cleaning of the mounting cavity convenient. Furthermore, the wall-scraping component moves along the inner wall in an arc-shaped trajectory, which agitates the water in the mounting cavity. The agitated water also has a cleaning effect on the blades and / or comb teeth. The reciprocating motion of the wall-scraping component makes the blades and / or comb teeth more thoroughly cleaned.

[0033] In some embodiments, the friction element includes a through hole through which the comb teeth pass; the through hole includes a first sealing lip and a second sealing lip, which close the through hole when the comb teeth exit the through hole; the comb teeth push aside the first sealing lip and the second sealing lip and pass through the through hole into the space between two adjacent blades.

[0034] As described above, when the comb teeth exit the through hole, the first sealing lip and the second sealing lip close the through hole, so that the ends of the comb teeth can also rub against the first sealing lip and the second sealing lip, making the comb teeth cleaner.

[0035] In some embodiments, the comb includes two combs arranged opposite to each other, each comb including a comb shaft with comb teeth; the comb driving device includes a first shaft, a comb driving motor, a second shaft, a transmission mechanism, two pull ropes, a connecting rod, and an elastic reset member. Each comb shaft has a connecting rod and an elastic reset member at each of its two ends; the connecting rod is also rotatably connected to the main body; the elastic reset member is also connected to the main body; the comb driving motor is connected to the first shaft via the transmission mechanism; the first shaft has two winding members spaced apart axially; the two ends of the second shaft and the two ends of the comb driving motor are respectively provided with rope receiving grooves. One end of each pull rope is fixed to the end of one comb shaft, and the other end is fixed to the end of the other comb shaft on the same side, and is wound around the winding member, the rope receiving groove on the side of the comb driving motor, and the rope receiving groove on the side of the second shaft.

[0036] As described above, the first shaft is driven by a comb drive motor, and the two comb shafts are pulled by two pull ropes, thus realizing one power source driving two combs. The pull ropes pull the comb shafts, causing the comb teeth to move between the first and second positions. The pull ropes are flexible, which facilitates the movement of the combs and reduces costs. In addition, there are two pull ropes located on both sides of the two combs as a whole. In this way, both ends of each comb shaft are driven, the comb shafts are balanced by force, the movement is smoother, and there is no situation where the comb teeth come into contact with the blades.

[0037] In some embodiments, the food processor includes a control panel; the control panel controls the air intake device to intake air and the water supply assembly to supply water; the control panel also controls the rotation of the blade assembly during the air intake process.

[0038] As described above, since the control board also controls the rotation of the blade assembly during the air intake process, the rotation allows the entire circumference of the blade assembly to be impacted by air bubbles, resulting in a better cleaning effect. Attached Figure Description

[0060] See Figure 2 and Figure 4 and combined Figure 1 , Figure 12 and Figure 13 This application discloses a food processor, which includes a blade assembly 10. The blade assembly includes a main body 1, blade components 2, a door assembly 3, a water supply assembly, and an air intake device. The main body 1 includes a mounting cavity 11. The structure of the main body 1 is not limited; see [reference needed]. Figure 2 , Figure 4 and Figure 13 and combined Figure 12 In this embodiment, the main body 1 includes an upper tool holder 19 and a lower tool holder 18, and the feeding structure 191 is disposed on the upper tool holder 19. See also Figure 9 and Figure 11The upper blade holder 19 and the lower blade holder 18, when closed, form the mounting cavity 11. Of course, the structure of the main body 1 is not limited to this. In embodiments of this application, the main body 1 can also serve as a mounting carrier for the blade assembly 2's blade drive device, blade comb drive device, etc. In this embodiment, the bottom outlet 111 of the mounting cavity 11 is located on the lower blade holder 18. To facilitate feeding (vegetables or meat, etc.), the main body 1 also includes a feeding structure 191 that communicates with the interior of the mounting cavity 11 and the exterior of the food processor. The feeding structure 191 is not limited; it allows food (vegetables or meat, etc.) to enter the mounting cavity 11 and be processed by the blades 21 of the blade assembly 2. See also... Figure 13 The main body 1 also includes a left gearbox cover 195, a left gearbox seat 196, a right gearbox cover 197, and a right gearbox seat 198. The left gearbox cover 195 and the left gearbox seat 196 are fitted together for the installation of corresponding gears. The right gearbox cover 197 and the right gearbox seat 198 are fitted together for the assembly of corresponding gears.

[0061] See Figure 2 and Figure 4 and combined Figure 10 , Figure 11 and Figure 12 The blade assembly 2 is installed within the mounting cavity 11 and located above the discharge port 111, and includes a blade 21. The blade assembly 2 is primarily used for processing food ingredients, and its structure is not limited. See also... Figure 7 and Figure 13 In this embodiment, the main body 1 also includes a blade assembly drive mechanism. The blade assembly drive mechanism includes a gear 192, a transmission assembly 193, and a blade assembly drive motor 194. The blade assembly drive motor 194 drives the transmission assembly 193. Under the combined action of the transmission assembly 193 and the gear 192, the two blade shafts 22 rotate in opposite directions, thereby enabling the blades 21 on the two blade shafts 22 to process food.

[0062] See Figure 2 and Figure 4 and combined Figure 12 The hatch assembly 3 is assembled with the main body 1 and includes a hatch 31. The hatch 31 is used to open or close the discharge port 111. When the hatch 31 closes the discharge port 111, the mounting cavity 11 forms at least a semi-closed cavity. The semi-closed cavity means that the mounting cavity 11 is also connected to the outside through the feeding structure 191, so that external food can enter the mounting cavity 11 and be processed by the knife assembly 2. The hatch 31 can be manually controlled to open or close the discharge port 111, or, as described later, the hatch 31 can be driven to move in different directions by the hatch drive assembly 32, thereby opening or closing the discharge port 111 accordingly. The structure of the hatch drive assembly 32 is not limited; see [link to relevant documentation]. Figure 6 and combined Figure 4 , Figure 2and Figure 12 In an embodiment of this application, the hatch assembly 3 includes a hatch bracket 391, a hatch sealing ring 392, a hatch base plate 393, a hatch motor cover 394, a proximity switch, and a hatch drive assembly 32; their assembly method is not limited. There are two proximity switches (such as the aforementioned first proximity switch 3951 and second proximity switch 3952), one for determining whether the hatch 31 is in the open position, and the other for determining whether the hatch 31 is in the closed position. The hatch drive assembly 32 includes a hatch drive motor 321, a lead screw 322, and a gear set 323 connecting the lead screw 322 and the hatch drive motor 321. See also... Figure 8 and combined Figure 9 The hatch drive motor 321 and lead screw 322 are assembled on the hatch motor cover 394. The hatch 31 is assembled on the hatch base plate 393. See also Figure 9 and combined Figure 4 and Figure 2 The hatch 31 is equipped with a threaded sleeve 310, and the lead screw 322 passes through and meshes with the threaded sleeve 310. The working process is as follows: the hatch drive motor 321 rotates, and drives the lead screw 322 to rotate through the gear set 323. The lead screw 322 meshes with the threaded sleeve 310, which can drive the hatch 31 to move back and forth in a straight line, in the following direction: Figure 7 As indicated by arrows R1 and R2, the discharge port 111 can be opened or closed. The door drive assembly 32 includes a lead screw 322 and a door drive motor 321. The door drive assembly 32 occupies a small space, making the opening and closing of the door 31 smoother and more convenient. In the above embodiment, the door drive assembly 32 includes a gear set 323. In some embodiments, the gear set can be omitted; for example, a section of the motor shaft of the door drive motor 321 can be the lead screw 322. Regardless of the method, it is sufficient that the door drive motor 321 can drive the lead screw 322.

[0063] In some embodiments, the food processor includes a control board and a door drive device (in this case, the door drive device may be the aforementioned lead screw 322 and lead sleeve 310, or it may not be); the door drive device is used to drive the door to open or close the discharge port, and includes a door drive motor 321; the food processor also includes a first inductive switch 3951; the first inductive switch 3951 generates a sensing signal when the door 31 completely closes the discharge port 111; the control board controls the door drive motor 321 to stop working according to the sensing signal; and / or, the food processor includes a second inductive switch 3952; the second inductive switch generates a sensing signal when the door 31 completely opens the discharge port 111; the control board controls the door drive motor 321 to stop working according to the sensing signal. The structures of the first inductive switch 3951 and the second inductive switch 3952 are not limited.

[0064] As described above, by setting the control panel and also setting at least one of the first and second inductive switches, the movement of the hatch can be automatically controlled.

[0065] See Figure 2 and Figure 3 and combined Figure 1 The water supply assembly is assembled on the main body 1. When the hatch 31 is closed and the discharge port 111 is closed, the water supply assembly supplies water to the mounting cavity 11 to soak the blade assembly 2. The soaking can be complete or partial. The structure of the water supply assembly is not limited. In the embodiments of this application, the water supply assembly includes a water tank 41 and a water pump 42.

[0066] See Figure 1 and Figure 2 The air intake device is connected to the mounting cavity 11, and gas is introduced into the water in the mounting cavity 11 to generate bubbles that can collide with the blade 21. The air intake device is not limited; in the embodiments of this application, the air intake device includes an air intake component 51 and an air pump 52. The air pump 52 supplies gas to the air intake component 51 and introduces gas into the water in the mounting cavity 11 through the air intake component 51. Figure 6 , Figure 7 and Figure 9 The structure of the air intake component 51 is shown in the diagram. Figure 1 The air pump 52 is shown. As for the positional relationship between the air intake device and the blade 21, it is sufficient that the air bubbles discharged from the air intake 51 can eventually collide with the blade 21 to clean the blade assembly 2.

[0067] As described above, since the blade assembly 2 is immersed in the mounting cavity 11, air bubbles are continuously generated through the air intake device. These bubbles continuously collide with the blade 21, causing the residue adhering to the blade 21 to detach from the blade 21 and dissolve into the water, thus cleaning the blade 21. After cleaning, the door 31 is opened to discharge water through the discharge port 111, achieving automatic cleaning of the blade assembly 2. It is not necessary to disassemble the blade assembly 2 for cleaning, nor is it necessary to use tools such as cleaning brushes, water guns, and slag scrapers. Cleaning is convenient. In addition, since the blade assembly 2 is located in the mounting cavity 11 during the cleaning process, and the mounting cavity 11 is a semi-enclosed cavity, the blade 21 is not exposed, and there is no safety hazard.

[0068] See Figure 2 and Figure 4 and combined Figure 7 , Figure 13 and Figure 14In an embodiment of this application, the blade assembly 2 includes two sub-blade assemblies 212, each of which includes a blade shaft 22 and a plurality of blades 21. The plurality of blades 21 are spaced apart along the axial direction of the blade shaft 22. The axes of the two blade shafts 22 are located on the same horizontal plane. The position of the horizontal plane can be referenced... Figure 2 , Figure 4 , Figure 10 and Figure 11 The position of the dashed line L, from Figure 2 , Figure 4 , Figure 10 and Figure 11 It can be concluded without a doubt that the air intake 51 is located below the blade assembly 2.

[0069] As described above, since the axes of the two blade shafts 22 are located on the same horizontal plane, and the air inlet 51 is located below the blade assembly 2, the air bubble moves from bottom to top and then strikes the blade 21 on the blade shaft 22 (the movement of the air bubble can be found in [reference]). Figure 7 , Figure 2 and Figure 4 The cleaning effect of the blade assembly 2 is good. In addition, this embodiment only needs to consider the positional relationship between the plane containing the air inlet 51 and the axis of the blade shaft 22, and can be applied to mounting cavities 11 of any shape.

[0070] See Figure 5 , Figure 6 and Figure 7 and combined Figure 2 The air intake device includes an air intake component 51 assembled with or integrally formed with the hatch 31. The air intake component 51 is provided with multiple air intake holes 511. The air intake component 51 moves synchronously with the hatch 31, and when the hatch 31 closes the discharge port 111, the air intake holes 511 are located below the blade assembly 2.

[0071] As described above, since the air inlet 51 is assembled or integrally formed with the hatch 31, when the hatch 31 closes the discharge port 111, the air inlet 511 is located below the blade assembly 2. This not only facilitates material discharge but also allows air bubbles to move upwards from the discharge port 111, traveling a longer distance, thus better cleaning the blade assembly 2 (e.g., greater impact force for better cleaning, or a longer travel distance to contact more parts of the blade 21 for cleaning, resulting in better cleaning). Finally, assembling or integrally forming the air inlet 51 with the hatch 31 integrates the air inlet 51 with the hatch assembly 3, facilitating the layout of other components. In the embodiments of this application, the surface of the air inlet 51 and the surface of the hatch 31 come into contact with water, while the back of the hatch 31 or the back of the hatch assembly 3 (opposite to the mounting cavity 11) does not come into contact with water, reducing the need for sealing structures, etc.

[0072] See Figure 6 , Figure 3 and Figure 5 and combined Figure 7 and Figure 9 The air intake 51 is embedded in the hatch 31, and the space between the air intake 51 and the hatch 31 forms an airflow channel 512 (e.g., Figure 3 and Figure 5 (As marked). The airflow channel 512 communicates with the plurality of air inlets 511. An air inlet 313 is provided on the hatch 31, communicating with the airflow channel 512 and the air pump 52. In an embodiment of this application, the top surface of the air inlet 51 is not higher than the top surface of the hatch 31. Figure 3 , Figure 5 , Figure 7 and Figure 9 In this context, "not higher than" means "flush with". Of course, "not higher than" also includes situations where the top surface of the air intake 51 is lower than the top surface of the hatch 31. In some embodiments, the top surface of the air intake 51 may also be higher than the top surface of the hatch 31.

[0073] As described above, under the conditions of facilitating material discharge and allowing for a longer bubble travel distance, the sum of the thicknesses of the air inlet 51 and the hatch 31 is relatively small (less than the sum of their thicknesses; in particular, when the top surface of the air inlet 51 is not higher than the top surface of the hatch 31, the sum of their thicknesses is at most the thickness of the hatch 31). This is equivalent to integrating two components into one, resulting in a simpler structure. It eliminates the need to consider the influence of the air inlet 51 on the movement of the hatch 31, making it easier to implement.

[0074] See Figure 6 , Figure 7 and Figure 9 and combined Figure 8 The hatch 31 includes a boss 311 and a groove 312 surrounding the boss 311. The air intake 51 is annular. See also Figure 5 and Figure 7 The air intake 51 is located within the groove 312 and the boss 311 is located within the ring of the air intake 51, so that the air intake 51 can be embedded in the hatch 31.

[0075] As described above, the boss 311 is located inside the ring of the air intake 51, and the air intake 51 is located inside the groove 312, making it easy to fit the air intake 51 into the hatch 31.

[0076] See Figure 10The blade assembly 2 includes two sub-blade assemblies 212, each of which includes a blade shaft 22. Blades 21 are spaced apart from the blade shaft 22 along its axial direction. The air intake device 5 includes an air intake element 51. Each sub-blade assembly 212 corresponds to one air intake element 51. The air intake element 51 includes an air inlet 511. The air intake element 51 is assembled to the sidewall of the mounting cavity 11 and located at the bottom of the mounting cavity 11.

[0077] See Figure 11 , Figure 11 The embodiments shown are the same as Figure 10 Compared to the illustrated embodiment, the difference lies in the installation position of the air intake device (especially the installation position of the air intake component 51). Specifically, Figure 10 The air intake component 51 of the central air intake device is installed on the side wall of the mounting cavity 11, while... Figure 11 In this configuration, the discharge port 111 includes a discharge port sidewall 112. The air inlet 51 is installed on the discharge port sidewall 112.

[0078] As described above, regardless of whether the air inlet 51 is installed on the side wall 112 of the discharge port or at the bottom of the mounting cavity 11, the air bubble travels a greater distance, thus improving the cleaning effect of the blade assembly 2. Similarly, the surface of the air inlet 51 contacts water, while the back of the air inlet 51 (opposite to the mounting cavity 11) does not, reducing the need for sealing structures, etc.

[0079] See Figure 7 and Figure 9 and combined Figure 8 The air intake component 51 includes an air intake surface facing the blade assembly 2, and the air intake surface is covered with air intake holes 511. Of course, the air intake component 51 may not be as... Figure 7 and Figure 9 In this way, the air intake 511 is hollow (not limited to a ring shape). The filling can be achieved in any way, such as a matrix, etc.

[0080] As described above, with the air intake component's surface covered with air intake holes 511, the air intake component 51 can discharge gas from multiple points, generating bubbles in multiple locations. This results in a larger cleaning range and better cleaning effect for the blade assembly 2. When the air intake component 51 is annular, the air intake holes 511 cover the entire ring. This allows for easy insertion of the air intake component 51 into the door 31, providing a larger cleaning range. Furthermore, this insertion method, where the protrusion 311 occupies part of the surface area of ​​the air intake component 51, effectively reduces the number of air intake holes 511 compared to a surface covered with air intake holes. This results in a higher pressure of the discharged gas, thus increasing the impact force on the food on the blade 21 and improving the cleaning effect.

[0081] See Figure 1 and Figure 2 The water supply assembly includes a water tank 41, a heating assembly (not shown), and a water pump 42. The heating assembly heats water from the water tank 41, and the water pump 42 pumps hot water into the mounting cavity 11; alternatively, the water pump 42 supplies water to the heating assembly, and the hot water from the heating assembly flows into the mounting cavity 11.

[0082] As described above, by soaking the knife assembly 2 in hot water, the hot water can dissolve food residue and grease, making it easier to clean the knife assembly 2 and resulting in a better cleaning effect.

[0083] See Figure 1 , Figure 4 , Figure 10 , Figure 11 , Figure 11 and Figure 13 The main body 1 is provided with a water inlet 12, which is connected to the mounting cavity 11 and is located at the top of the mounting cavity 11.

[0084] As described above, since the water inlet 12 is located at the top of the mounting cavity 11, water flows down from top to bottom, resulting in better cleaning of the blade assembly 2. This is especially true when the water is hot. The water inlet 12's location at the top of the mounting cavity also prevents water backflow.

[0085] See Figure 2 , Figure 3 , Figure 4 and Figure 5 and combined Figure 14 , Figure 16 , Figure 13 and Figure 12 The comb 61 includes spaced-apart comb teeth 611. In this embodiment, the comb 61 includes a comb shaft 612. The comb teeth 611 are spaced-apart on the comb shaft 612.

[0086] See Figure 2 , Figure 3 , Figure 4 and Figure 5 The friction element 6 rubs against the comb teeth 611. The structure of the friction element 6 is not limited, nor is the manner in which the friction element 6 rubs against the comb teeth 611, as long as the food stuck to the comb teeth 611 can be washed away. Of course, for the subsequent reciprocating motion of the comb teeth, the friction element 6 may not be necessary.

[0087] See Figure 16 and Figure 14 and combined Figure 2 , Figure 3 , Figure 4 and Figure 5 , and see Figure 17 , Figure 18 and Figure 19 The comb drive device 7 drives the comb 61 to reciprocate between a first position and a second position. The structure of the comb drive device 7 is not limited; for example, for... Figure 18 and 19 The straight comb teeth 611 shown can be represented by a telescopic drive device 7. Figure 16 and Figure 17 The arc-shaped comb teeth 611 shown, the structure of the comb drive device 7 can be as follows: See Figure 16 and Figure 14 and combined Figure 2 and Figure 4 The comb 61 includes two combs arranged opposite each other, each comb 61 including a comb shaft 612 with comb teeth 611. The comb drive device 7 includes a first shaft 70, a comb drive motor 71, a second shaft 72, a transmission mechanism 73, two pull ropes (e.g., steel wires) 74, a connecting rod 75, and an elastic reset member 76 (e.g., a tension spring). Each comb shaft 612 has a connecting rod 75 and an elastic reset member 76 at each of its two ends. Figure 16 As shown, the two comb shafts 612 have four ends, a total of four connecting rods 75 and four elastic reset members 76. The connecting rods 75 are also rotatably connected to the main body 1, and can be connected to any part of the main body 1 that allows rotation; for example, see [reference needed]. Figure 13In this embodiment, the connecting rod 75 is connected to the pivot 181 of the lower blade holder 18. The elastic reset member 76 is also connected to the main body 1. The comb drive motor 71 is connected to the first shaft 70 through the transmission mechanism 73. The transmission mechanism 73 is not limited to a gear set and can also be a transmission belt. The first shaft 70 has two winding members 701 spaced apart along the axial direction. The structure of the winding members 701 is not limited, as long as it can allow the pull rope 74 to be wound or released. The two ends of the second shaft 72 and the two ends of the comb drive motor 71 are respectively provided with rope receiving grooves 721. The two ends of the second shaft 72 can be respectively provided with rope receiving members 722. The rope receiving members 722 can be integrally formed with the second shaft 72 or assembled on the second shaft 72. For the comb drive motor 71, the rope receiving members 722 can be fixed on the comb drive motor 71. Of course, one of the rope receiving members 722 passes through the motor shaft of the comb drive motor 71. The rope receiving grooves 721 are formed on the rope receiving components 722 of both the second shaft 72 and the comb drive motor 71. The rope receiving grooves 721 guide the pull rope rather than winding it like the winding component 701. Rope receiving grooves 721 are provided at both ends of the second shaft 72 and both ends of the comb drive motor 71. The term "located" is not limited to the rope receiving components 722 being located on the comb drive motor 71 and the second shaft 72; they can also be located on other components, as long as they are located at both ends of the second shaft 72 and the comb drive motor 71. One end of each pull rope 74 is fixed to the end of one comb shaft 612, and the other end is fixed to the end of another comb shaft 612 on the same side, and is wound around the winding component 701, with rope receiving grooves 721 located on the side of the comb drive motor 71 and the second shaft 72.

[0088] See Figure 16 and Figure 14 and combined Figure 3 and Figure 5The working principle of the comb drive device 7 is as follows: the comb drive motor 71 rotates in a first direction (e.g., forward rotation), and then drives the first shaft 70 to rotate through the transmission mechanism 73. The winding member 701 on the first shaft 70 rotates, and the rotation of the winding member 701 winds the pull rope 74 around the winding member 701, thereby pulling the four connecting rods 75 at both ends to rotate. The rotation of the connecting rods 75 drives the two comb shafts 612 to rotate. At this time, the elastic reset member 76 is tightened by force, for example, the tightening corresponds to the comb teeth 611 moving from the first position to the second position. When the comb drive motor 71 rotates in a second direction opposite to the first direction (e.g., reverse rotation), the first shaft 70 rotates in the opposite direction, causing the winding member 701 to rotate and release the pull rope 74. At this time, the elastic reset member 76 restores its deformation, corresponding to the comb teeth 611 moving from the second position to the first position. Thus, through the forward and reverse rotation of the comb drive motor 71 and the aforementioned transmission relationship, the comb teeth 611 reciprocate between the first position and the second position.

[0089] The blade-comb drive device 7 with the above structure drives the first shaft 70 through a blade-comb drive motor 71, and pulls the two blade-comb shafts 612 through two pull ropes 74, realizing one power source driving two blade-combs. In addition, the pull ropes 74 pull the blade-comb shafts 612 to make the comb teeth move between the first position and the second position. The pull ropes are flexible, which facilitates the movement of the blade-combs and is low in cost. In addition, there are two pull ropes located on both sides of the two blade-combs 61 as a whole. In this way, both ends of each blade-comb shaft 612 are driven, the blade-comb shafts are balanced by force, the movement is smoother, and there will be no situation where the comb teeth abut against the blades.

[0090] See Figure 2 , Figure 3 , Figure 4 and Figure 5 and combined Figure 12 and Figure 14 In the first position, the comb teeth 611 are located between each pair of adjacent blades 21. See also Figure 11 and Figure 12 In the second position, the comb 61 is at least partially withdrawn between two adjacent blades 21. This can be understood from the following: Figure 11 In the first position, the left-hand comb tooth 611 is not disengaged from between the two adjacent blades 21, while the right-hand comb tooth 61 is disengaged from between the two adjacent blades 21 and is in the second position. Of course, the first and second positions of the comb tooth 611 do not have to be in the aforementioned states; for example, in the second position, it may not be disengaged from between the two adjacent blades 21, as long as the purpose of cleaning the comb tooth 611 is achieved. See also... Figure 2 , Figure 3 , Figure 4 and Figure 5The comb teeth 611 rub against the friction element 6 during the movement.

[0091] As described above, the blade assembly 2 is immersed in the mounting cavity 11, and the blade comb driving device 7 drives the blade comb 61 to reciprocate between a first position and a second position. During this movement, the blade comb 611 rubs against the friction element 6, which peels away food adhering to the blade comb 611, achieving automatic cleaning. Cleaning the blade comb is convenient; for example, it is easy to clean without removing the blade comb 61 from the mounting cavity 11. Furthermore, the reciprocating motion of the blade comb 611 allows for repeated scrubbing against the friction element 6, resulting in thorough cleaning. In the first position, the blade comb 611 is positioned between two adjacent blades 21; in the second position, the blade comb 611 is withdrawn from between two adjacent blades 21. The longer stroke of the blade comb 611 results in more thorough cleaning. Furthermore, the reciprocating motion of the blade comb 611 between two adjacent blades 21 also separates food adhering to the blades 21, and combined with the water flow driven by the blade comb 611, it also cleans the blades 21. Furthermore, when the comb teeth 611 are in the first position, rotating the blade assembly 2 causes water to move, and the blade assembly (especially the blades) is cleaned through the cooperation between the blade assembly 2, the comb teeth 611 and the moving water.

[0092] Technicians will understand that, even without the friction element 6, the reciprocating motion of the comb teeth 611 can still remove food from the blades 21, achieving the purpose of cleaning the blade assembly. Combined with the water flow driven by the comb teeth 611, the cleaning effect on the blades is excellent. In the first position, the comb teeth are positioned between two adjacent blades; in the second position, the comb teeth are disengaged from between two adjacent blades. Therefore, the stroke of the comb teeth is longer, resulting in a more thorough cleaning.

[0093] See Figure 15 and combined Figure 2 , Figure 4 , Figure 12 , Figure 17 , Figure 18 and Figure 19 The food processor includes a scraper 81 and a scraper drive 82. The scraper 81 is located within the mounting cavity 11. Based on the functions described later, the structure of the scraper 81 is not limited; in this embodiment, such as... Figure 12 As shown, the wall scraping component 81 includes a cleaning rod 811 and a soft brush 812 disposed on the cleaning rod 811. Figure 12In this embodiment, a soft brush 812 encloses the cleaning rod 811. The wall-scraping drive device 82 is connected to the wall-scraping component 81. In this embodiment, the wall-scraping component 81 is assembled on a fixing frame 83, and the fixing frame 83 is connected to the wall-scraping drive device 82 to achieve connection between the wall-scraping component 81 and the wall-scraping drive device 82. (See also...) Figure 4 , Figure 12 , Figure 17 , Figure 18 and Figure 19 The scraping drive device 82 drives the scraping component 81 to reciprocate along the inner wall 110 of the mounting cavity 11 (in this embodiment, including the inner top wall and the inner side walls located at both ends of the inner top wall) to scrape the inner wall 110. The structure of the scraping drive device 82 is not limited, as long as it can achieve the aforementioned function. In this embodiment, the scraping drive device 82 includes a scraping drive motor 821 and a scraping transmission assembly (in this embodiment, a scraping transmission gear 822). The rotation of the scraping drive motor 821 drives the scraping transmission gear 822 to rotate. Figure 4 The angle b of rotation of the wall scraping component 81 is shown (in this embodiment, b = 260 degrees), which in turn drives each wall scraping component 81 (soft brush 812) to rotate and scrape the inner wall 110.

[0094] As described above, the wall-scraping drive device 82 drives the wall-scraping component 81 to scrape the inner wall 110 of the mounting cavity 11, making cleaning of the mounting cavity 11 convenient. Furthermore, the wall-scraping component 81 moves along the inner wall 110 in an arc-shaped trajectory, which agitates the water in the mounting cavity 11. The agitated water also has a cleaning effect on the blade 21 and / or comb teeth 611. The reciprocating motion of the wall-scraping component 81 makes the blade 21 and / or comb teeth 611 more thoroughly cleaned.

[0095] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 16 The comb teeth 611 are arc-shaped, and the comb drive device 7 drives the comb 611 to rotate, causing the comb teeth 611 to move along an arc trajectory. In this embodiment, the comb drive device 7 can be the aforementioned comb drive device, or other comb drive devices, as long as they can achieve the rotation of the comb.

[0096] As described above, since the comb teeth 611 are arc-shaped and move along an arc trajectory, on the one hand, the comb teeth 611 have high strength and are not easily deformed. For example, they can reciprocate between two adjacent blades 21 without deforming and causing the end of the comb teeth 611 to abut against one of the blades 21, preventing the comb teeth from reciprocating or breaking. This allows for better removal of food stuck to the blades 21 and easier frictional contact with the friction element 6. On the other hand, see... Figure 2 and Figure 17 When the arc-shaped comb teeth 611 are in the second position, the two comb teeth 611 are roughly in a figure-eight shape, making room for the space corresponding to the discharge port 111 to be larger, so that more and faster material is discharged during operation.

[0097] See Figure 18 and Figure 19 The comb teeth 611 are straight, and the comb drive device 7 drives the comb teeth 611 to extend and retract along a straight trajectory. Figure 19 The dashed lines and comparison Figure 18 It can be seen that the comb teeth 611 reciprocate along a straight trajectory. In this embodiment, the comb drive device 7 is a telescopic device.

[0098] As described above, the comb teeth 611 are straight, making the comb 61 easy to process and simplifying the structure of the comb drive device 7. This is because any drive device that achieves linear reciprocating motion can be used as the comb drive device 7, such as a combination of a lead screw and a thread.

[0099] See Figure 17 The comb 61 is mounted on the top of the main body 1. Those skilled in the art will understand that, for Figure 18 and Figure 19 The illustrated embodiment of the comb drive device 7 driving the comb teeth 611 to reciprocate along a straight trajectory can also have the straight comb teeth 611 located on the top of the main body 1.

[0100] As described above, since the comb 61 is installed on the top of the main body 1, there is no need to consider the sealing structure between the comb 61 and the main body 1, resulting in a simple structure.

[0101] See Figure 2 and Figure 4 and combined Figure 18 and Figure 19 The comb 61 is installed at the bottom of the main body 1.

[0102] As described above, since the comb 61 is installed at the bottom of the main body 1, whether it is a straight comb tooth 611 or an arc-shaped comb tooth 611, when the comb tooth 611 is in the second position, the two comb teeth 611 are roughly in a figure-eight shape, freeing up space so that the space corresponding to the discharge port 111 is larger, and more and faster material is discharged during operation.

[0103] See Figure 2 , Figure 3 , Figure 4 and Figure 5 and combined Figure 18 The friction element 6 is a seal that seals the side wall between the hatch 31 of the hatch assembly 3 and the discharge port 111.

[0104] As described above, on the one hand, the friction element 6 seals the discharge port 111 of the hatch 31, preventing water from leaking out of the mounting cavity 11. On the other hand, it peels off the food stuck to the comb teeth 611. Therefore, by integrating two functions, it can save on parts.

[0105] See Figure 3 and Figure 5 The sealing element includes a through hole 610 through which the comb teeth 611 pass; the hatch assembly 3 includes a water receiving groove 320 communicating with the through hole 610, the water receiving groove 320 being located at the edge of the hatch assembly. The manner of communication is not limited, as long as water carried out from the through hole 610 by the comb teeth 611 can flow into the water receiving groove 320. Figure 3 and Figure 5 The direction of water flow is indicated by dashed lines and black arrows. The food processor includes a receiving container 20. The receiving container 20 is located below the water receiving tank 320, so that water in the water receiving tank 320 flows into the receiving container 20.

[0106] As described above, water flowing out of the through hole 610 during the reciprocating motion of the comb teeth 611 can flow into the receiving box 20 through the water receiving trough 320. This facilitates the collection of overflowing water. Furthermore, the water receiving trough 320 is located on the hatch assembly 3 and at the edge of the hatch assembly 3, without occupying the space of other components, and it is also convenient to process the water receiving trough 320 on the hatch assembly 3.

[0107] See Figure 3 and Figure 5 The sealing element includes a first sealing lip 621 and a second sealing lip 622. When the comb teeth 611 retract from the through hole 610, the first sealing lip 621 and the second sealing lip 622 close the through hole 610. Figure 4 Point c on the right side indicates that the first sealing lip 621 and the second sealing lip 622 are closed; the comb teeth 611 open the first sealing lip 621 and the second sealing lip 622 and pass through the through hole 610 into the space between two adjacent blades 21.

[0108] As described above, when the comb teeth 611 retract from the through hole 610, the first sealing lip 621 and the second sealing lip 622 close the through hole 610 to prevent water from overflowing from the mounting cavity 11. Furthermore, when the comb teeth 611 retract from the through hole 610, the first sealing lip 621 and the second sealing lip 622 close the through hole 610, so that the ends of the comb teeth 611 can also rub against the first sealing lip 621 and the second sealing lip 622, making the comb teeth cleaner.

[0109] Inspired by the functions of the first sealing lip 621 and the second sealing lip 622 of the aforementioned seal and the fact that the friction element is also a seal, even when the friction element 6 is not a seal, the comb teeth can still be cleaned by using the aforementioned relationship between the first sealing lip 621 and the second sealing lip 622.

[0110] See Figure 1 and Figure 12 The main body 1 is provided with an overflow hole 16 that connects to the mounting cavity; the overflow hole 16 is connected to the water receiving tank 320 through a drainage pipe.

[0111] As described above, due to the overflow hole 16, if there is too much water in the mounting cavity 11, it will flow from the overflow hole 16 into the water receiving tank 320 through the drain pipe. This prevents excessive water from entering the mounting cavity 11.

[0112] See Figure 1 and Figure 2 The water supply assembly includes a water tank 41, a heating assembly (not shown), and a water pump 42. The heating assembly heats water from the water tank 41, and the water pump 42 pumps hot water into the mounting cavity 11; alternatively, the water pump 42 supplies water to the heating assembly, and the hot water from the heating assembly flows into the mounting cavity 11.

[0113] As described above, by soaking the blade assembly 2 in hot water, the hot water can dissolve food residue and grease, making it easier to clean the comb teeth 611 (and also easier to clean the inner wall 110 when the scraper is provided), resulting in a better cleaning effect.

[0114] See Figure 1 and Figure 2 This application also discloses a food processor. The food processor includes any of the aforementioned blade assembly 10 and a control board; the control board controls the air intake device to intake air and the water supply assembly to supply water; the control board also controls the rotation of the blade assembly during the air intake process. Figure 1 and Figure 2 The diagram also illustrates that the food processor includes a receiving container 20, an upper shell 30, a lower shell 40, and a bottom cover 50. After the ingredients are cut by the blade assembly 2, they fall into the receiving container 20 from the discharge port 111. The upper shell 30 and the lower shell 40, when assembled, form the outer casing of the food processor. The bottom cover 50 is located at the bottom of the lower shell 40.

[0115] As described above, since the control board also controls the rotation of the blade assembly 2 during the air intake process, the rotation allows the entire circumference of the blade assembly 2 to be impacted by air bubbles, resulting in a better cleaning effect and reducing the need for an air intake device.

[0116] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
