[0001] The present application relates to the technical field of multifunctional food processors, in particular to a food processor. BACKGROUND

[0002] With the increasing improvement of people's living standards, many different types of food processors appear on the market. The functions of the food processor include but are not limited to mincing meat and kneading dough.

[0003] Taking a dough kneading food processor and a meat mincing food processor as examples, the meat mincing food processor needs to cut and crush the meat, and the working speed is relatively high. The dough kneading food processor needs to beat the dough, and the working speed is relatively low. The existing food processor has a single speed, and usually cannot be compatible with two functions with different required speeds such as dough kneading and meat mincing, which reduces the user experience. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a food processor which can output two different speeds to be compatible with two functions with different required speeds, thereby improving the user experience.

[0005] A food processor, comprising: a main machine comprising a motor; a bowl having a stirring cavity; a stirring assembly arranged in the stirring cavity; and a speed reducer detachably connected with the motor, used to reduce the speed of the motor when connected with the motor; wherein the food processor has a first mode and a second mode, in the first mode, the bowl is assembled to the main machine, the stirring assembly is connected with the motor, used to work at a first speed under the driving of the motor; in the second mode, the speed reducer is connected with the motor, and the stirring assembly is connected with the speed reducer, used to work at a second speed lower than the first speed after the motor is driven and the speed is reduced by the speed reducer.

[0006] The present application can make the stirring assembly beat the food material at two different speeds by detaching or mounting the speed reducer, so as to be compatible with two functions with different required speeds, thereby improving the user experience. Compared with the meat mincing food processor with dough kneading function which integrates a two-stage speed reducer, the two-stage speed reducer needs double shaft output, and its structure is relatively complex and occupies a large space. The present application can output two different speeds by mounting and detaching the speed reducer, and has a relatively simple structure and occupies a small space.

[0007] Optionally, the stirring assembly comprises a first stirring piece and a second stirring piece, the first stirring piece is used to beat a first type of food material, the shape of the second stirring piece is different from that of the first stirring piece, and the second stirring piece is used to beat a second type of food material different from the first type; in the first mode, the first stirring piece is connected with the motor; in the second mode, the second stirring piece is connected with the speed reducer.

[0008] Thus, the first stirring piece and the second stirring piece are respectively designed for different types of food materials and working rotating speeds, each stirring piece operates in a more suitable working condition, reducing excessive wear of the stirring piece caused by mismatched food material processing, and also speeding up the processing speed of different types of food materials.

[0009] Optionally, the first stirring piece is a meat mincing knife, the second stirring piece is a dough kneading knife, and the ratio of the first rotating speed to the second rotating speed is 5 to 15.

[0010] The ratio of the first rotating speed to the second rotating speed is set to 5 to 15, so that the meat mincing knife can efficiently perform the rapid mincing function at a high rotating speed when processing meat, and the dough kneading knife can knead the dough at a low rotating speed when processing the dough, which enables both types of food materials to be processed at their respective suitable stirring intensity and rhythm, greatly optimizing the processing effect of the food processor on different food materials.

[0011] Optionally, the speed reduction device comprises a speed reduction box and a connector; the speed reduction box has an output connecting head connected with the stirring assembly; the connector comprises a motor connecting head connected with the motor and a gear part engaged with the speed reduction box.

[0012] The speed reduction device adopts a design of a speed reduction box and a connector in a split modular manner, reducing the structural complexity of the entire speed reduction device, and facilitating the connection of the speed reduction device with the motor.

[0013] Optionally, the connector further comprises a connecting shaft between the motor connecting head and the gear part, and the speed reduction device further comprises a fixedly arranged bearing sleeved on the connecting shaft. The bearing can provide good support for the connecting shaft, so that the connecting shaft maintains high precision coaxiality and small radial runout during rotation.

[0014] Optionally, the speed reduction device comprises a housing and a speed reduction box, the housing comprises an upper housing and a lower housing, the upper housing is buckled with the lower housing to form a mounting space, and the speed reduction box is detachably mounted in the mounting space.

[0015] Optionally, a first connecting rib is arranged on the side of the upper housing facing the main machine, the main machine is provided with a first connecting groove, and the first connecting rib and the first connecting groove are clamped and fitted to assemble the speed reduction device on the main machine.

[0016] Optionally, the main body further comprises a micro switch and a switch connecting rod connected thereto, the micro switch is connected to the motor and has a closed state to make the circuit in which the motor is located conductive and an open state to make the circuit in which the motor is located non-conductive; wherein the switch connecting rod is located in the first connecting groove, when the first connecting rib is matched with the first connecting groove, the first connecting rib triggers the switch connecting rod to switch the micro switch from the open state to the closed state. This avoids accidental injury caused by user's negligence (such as mistakenly touching the motor switch without installing the bowl or the speed reducer).

[0017] Optionally, the bowl comprises a bowl body and a bowl cover, the bowl cover is assembled at the bowl opening of the bowl body; wherein the lower shell is provided with a second connecting groove on the side facing the bowl cover, the bowl cover has a second connecting rib, the second connecting rib is matched with the second connecting groove to make the speed reducer installed on the bowl. This matching mode is relatively simple to operate, without the need of using complex tools such as screwdrivers and wrenches, which is convenient for users to operate and assemble at home.

[0018] Optionally, the shape of the first connecting rib is the same as that of the second connecting rib;

[0019] In the first mode, the second connecting rib is matched with the first connecting groove to assemble the bowl on the main body;

[0020] In the second mode, the first connecting rib is matched with the first connecting groove to assemble the speed reducer on the main body.

[0021] After being thus arranged, since the shape of the first connecting rib is the same as that of the second connecting rib, the main body only needs to open the same type of first connecting groove, which can be assembled with the bowl in the first mode and assembled with the speed reducer in the second mode. This not only reduces the complexity of the connection structure of the main body, but also makes the operation logic more intuitive and simple when the user assembles the food processor to switch different modes. Whether the bowl is installed on the main body to be in the first mode or the speed reducer is assembled on the main body to be in the second mode, the user only needs to align the connecting rib and the connecting groove to operate in the same matching mode.

DETAILED DESCRIPTION

[0031] The present application provides a food processor capable of outputting two different rotational speeds to provide two functions (e.g., meat mincing and dough mixing) with different required rotational speeds. The food processor is described in detail below with reference to the accompanying drawings, and the features in the following embodiments and implementation manners can be combined with each other without conflict.

[0032] Please refer to Figures 1 to 3 . Figure 1 is an exploded structural view of the food processor shown in an embodiment; Figure 2 is a cross-sectional view of the food processor in a first mode; Figure 3 is a cross-sectional view of the food processor in a second mode.

[0033] The food processor includes a main machine 10, a bowl 30, a stirring assembly 40, and a speed reducer 20.

[0034] The main machine 10 comprises a main machine shell 11 and a motor 12 installed in the main machine shell 11 for providing driving force to the stirring assembly 40. The bowl 30 has a stirring cavity 33. The stirring assembly 40 is arranged in the stirring cavity 33 for whipping food materials in the stirring cavity 33. The speed reducer 20 is detachably connected with the motor 12, and the speed reducer 20 is used to reduce the rotating speed of the motor 12 when connected with the motor 12.

[0035] The food processor has a first mode and a second mode. In the first mode, the bowl 30 is assembled to the main machine 10, and the stirring assembly 40 is connected with the motor 12 for working at a first rotating speed under the driving of the motor 12. In the second mode, the speed reducer 20 is connected with the motor 12, and the stirring assembly 40 is connected with the speed reducer 20 for working at a second rotating speed lower than the first rotating speed under the driving of the motor 12 and the speed reduction of the speed reducer 20.

[0036] That is, when the food processor is in the first mode, the motor 12 is directly connected with the stirring assembly 40 to drive the stirring assembly 40 to stir food materials in the stirring cavity 33 at a high first rotating speed. When the food processor is in the second mode, the motor 12 is connected with the stirring assembly 40 through the speed reducer 20 to drive the stirring assembly 40 to stir food materials in the stirring cavity 33 at a low second rotating speed.

[0037] As known from the above description, the stirring assembly 40 can work at two different rotating speeds by the detachment or installation of the speed reducer 20. When the stirring assembly 40 works at the high first rotating speed, it can be used for mincing meat, making soy milk, milk shake and other food processing requiring fast stirring. When the stirring assembly 40 works at the low second rotating speed, it can be used for kneading dough and other food processing requiring slow stirring. Therefore, the present scheme can make the stirring assembly 40 whip food materials at two different rotating speeds to be compatible with two functions requiring different rotating speeds. Moreover, compared with a mincing food processor with a kneading function and an integrated secondary speed reducer, since the secondary speed reducer needs to output double shafts, its structure is relatively complex and occupies a large space. The present scheme can output two different rotating speeds by the installation and detachment of the speed reducer 20, and the structure is relatively simple and occupies a small space.

[0038] In an embodiment, the stirring assembly 40 comprises a first stirring member and a second stirring member, the first stirring member is used for whipping a first type of food materials, and the second stirring member has a shape different from that of the first stirring member and is used for whipping a second type of food materials different from the first type; in the first mode, the first stirring member is connected with the motor 12, and in the second mode, the second stirring member is connected with the speed reducer 20. The first type of food materials can be meat, and the second type of food materials can be dough, but are not limited thereto.

[0039] In this way, the first stirring member and the second stirring member are respectively designed for different types of food materials and working speeds, each of which operates in a more suitable working condition, reducing the excessive wear of the stirring member caused by the mismatched food material processing, and also speeding up the processing speed of different types of food materials. Meanwhile, the speed reduction device 20, as an intermediate part connecting the motor 12 and the stirring assembly 40, can block the second type of food material in the stirring cavity 33 from entering the motor 12, avoiding the pollution of the motor 12 by flour and the like.

[0040] Of course, in some other embodiments, the stirring assembly 40 can only include one stirring member, which can be connected with the motor 12 in the first mode and connected with the speed reduction device 20 in the second mode.

[0041] Further, the first stirring member is a meat grinder 41 to quickly grind meat at the first speed, and the second stirring member is a dough kneader 42 to quickly knead dough at the second speed. Moreover, the ratio of the first speed to the second speed is 5 to 15.

[0042] It is easy to understand that meat needs to be quickly and powerfully cut and stirred, so the demand for the first speed is higher; while dough needs to be more gently kneaded and stirred, and the lower second speed is more suitable. Therefore, the ratio of the first speed to the second speed is set to 5 to 15 in this scheme, so that the meat grinder 41 can efficiently play the function of quickly grinding meat at a higher speed when processing meat, and the dough kneader 42 can also knead dough at a lower speed when processing dough, which enables both types of food materials to be processed at their respective suitable stirring intensity and rhythm, greatly optimizing the processing effect of the food processor on different food materials.

[0043] For example, the ratio of the first speed to the second speed can be 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, but is not limited thereto. For example, the first speed is 3000 rad / min, and the second speed is 500 rad / min.

[0044] It should be noted that in order to make the ratio of the first speed to the second speed between 5 to 15, the speed reduction ratio of the speed reduction device 20 is between 1:5 to 1:15. The specific structure of the speed reduction device 20 to achieve this speed reduction ratio can refer to related technologies, which are not limited in this application.

[0045] Please refer to Figure 4 , Figure 4 is a partial structure diagram of the speed reduction device,

[0046] In one embodiment, the speed reduction device 20 further includes a housing 21, the housing 21 includes an upper housing 211 and a lower housing 212, the upper housing 211 is buckled with the lower housing 212 to form a mounting space 213, and the speed reduction box 22 is detachably installed in the mounting space 213.

[0047] On one hand, the design of the buckling of the upper shell 211 and the lower shell 212 makes the reduction device 20 simple and easy to assemble in the production process. The worker only needs to place the reduction box 22 in the corresponding position in the prepared lower shell 212, and then buckle the upper shell 211, so as to complete the installation of the reduction box 22 in the shell 21, which can significantly improve the assembly efficiency on the production line. On the other hand, when the reduction box 22 fails or needs to be maintained, the reduction box 22 can be disassembled from the shell 21, which is convenient for maintenance or replacement.

[0048] Specifically, the upper shell 211 is provided with a plurality of buckles 2111, and the lower shell 212 is provided with a plurality of card seats 2121. The plurality of buckles 2111 and the plurality of card seats 2121 are one-to-one corresponding in cooperation. The buckle 2111 and the card seat 2121 are connected and matched to assemble the upper shell 211 and the lower shell 212. The reduction box has a plurality of first installation holes 221, and the lower shell 212 has a plurality of second installation holes 2122. The plurality of first installation holes 221 and the plurality of second installation holes 2122 are one-to-one corresponding. Screws can be arranged in the corresponding first installation hole 221 and the second installation hole 2122, so that the reduction box 22 can be detachably installed in the installation space 213.

[0049] Please refer to Figure 4 and Figure 5 , Figure 4 is a partial structure diagram of the reduction device, Figure 5 is a three-dimensional structure diagram of the host.

[0050] In one embodiment, the side of the upper shell 211 facing the host 10 is provided with a first connecting rib 2112, and the host 10 is provided with a first connecting groove 111. The first connecting rib 2112 and the first connecting groove 111 are connected and matched to assemble the reduction device 20 to the host 10.

[0051] This kind of connection and matching mode is relatively simple to operate. Only the first connecting rib 2112 of the upper shell 211 of the reduction device 20 is aligned with the corresponding first connecting groove 111 of the host 10, and the first connecting rib 2112 can be buckled into the connecting groove, so as to complete the connection and assembly of the two. The whole process does not need to use screwdrivers, wrenches and other complex tools, which is convenient for users to operate at home.

[0052] Please refer to Figure 6 , Figure 6 is an assembly diagram of the lower shell and the outer cover of the reduction device.

[0053] The bowl 30 comprises a bowl body 31 and a bowl cover 32 assembled at the bowl mouth of the bowl body 31. The lower shell 212 is provided with a second connecting groove 2123 on the side facing the bowl cover 32, and the bowl cover 32 is provided with a second connecting rib 321 which is snap-fitted with the second connecting groove 2123 to assemble the speed reducer 20 to the bowl 30.

[0054] Similarly, the user can complete the assembly of the speed reducer 20 and the bowl 30 without tools, which is convenient for the user to operate at home.

[0055] In a further embodiment, the first connecting rib 2112 has the same shape as the second connecting rib 321; in the first mode, the second connecting rib 321 is snap-fitted with the first connecting groove 111 to assemble the bowl 30 to the main machine 10; in the second mode, the first connecting rib 2112 is snap-fitted with the first connecting groove 111 to assemble the speed reducer 20 to the main machine 10.

[0056] After such an arrangement, since the first connecting rib 2112 and the second connecting rib 321 have the same shape, the main machine 10 only needs to open the same type of first connecting groove 111 to assemble the bowl 30 in the first mode and the speed reducer 20 in the second mode. This not only reduces the complexity of the connecting structure of the main machine 10, but also makes the operation logic more intuitive and simple when the user assembles the food processor to switch between different modes. Whether it is to install the bowl 30 on the main machine 10 to be in the first mode or to assemble the speed reducer 20 to the main machine 10 to enter the second mode, the user only needs to align the connecting ribs and the connecting grooves according to the same snap-fitting mode.

[0057] It should be noted that the first connecting rib 2112 and the second connecting rib 321 are the same in number and are multiple, and the first connecting groove 111 is also multiple in number, the multiple first connecting grooves 111 correspond one-to-one to the multiple first connecting ribs 2112 and the multiple second connecting ribs 321.

[0058] Please continue to refer to Figures 4 to 6 In an embodiment, the main machine 10 further comprises a micro switch and a switch connecting rod 13 connected thereto, the micro switch is connected with the motor 12 and has a closed state to make the circuit in which the motor 12 is connected conductive and an open state to make the circuit in which the motor 12 is connected disconnected. In other words, when the micro switch is in the closed state, the circuit in which the motor 12 is connected is conductive, at this time the user can start the motor 12 by pressing the power supply, and when the micro switch is in the open state, the circuit in which the motor 12 is connected is disconnected, even if the user presses the power supply, the motor 12 will not be started.

[0059] The switch connecting rod 13 is located in the first connecting groove 111, and the first connecting rib 2112 triggers the switch connecting rod 13 when the first connecting rib 2112 is in clamping fit with the first connecting groove 111, so that the micro switch is switched from the open state to the closed state.

[0060] Similarly, the second connecting rib 321 of the bowl cover 32 can also trigger the switch connecting rod 13 when the second connecting rib 321 is in clamping fit with the first connecting groove 111 of the main machine 10, so that the micro switch is closed.

[0061] After the first connecting rib 2112 is in clamping fit with the first connecting groove 111, the micro switch is in the closed state only when the user assembles the speed reducer 20, so as to avoid accidental injury caused by user's negligence (such as mistakenly turning on the motor 12 switch without properly installing the bowl 30 or the speed reducer 20).

[0062] Please refer to Figure 7 , Figure 7 is an exploded structural view of the speed reducer.

[0063] In an embodiment, the speed reducer 20 further comprises a connector 23; the speed reducer box 22 has an output connecting head 222 connected with the and face knife of the stirring assembly 40; the connector 23 comprises a motor connecting head 231 connected with the motor 12 and a gear part 232 engaged with the speed reducer box 22, so that the speed reducer box 22 is connected with the motor 12.

[0064] The speed reducer 20 adopts the design of the modularization of the speed reducer box 22 and the connector 23, which reduces the structural complexity of the whole speed reducer 20 and facilitates the connection of the speed reducer 20 with the motor 12.

[0065] Further, the connector 23 further comprises a connecting shaft 233 located between the motor connecting head 231 and the gear part 232, and the speed reducer 20 further comprises a fixedly arranged bearing 24 sleeved on the connecting shaft 233. The connecting shaft 233 located between the motor connecting head 231 and the gear part 232 in the connector 23 enables the power of the motor 12 to be smoothly transmitted to the speed reducer box 22. The bearing 24 can provide good support for the connecting shaft 233, so that the connecting shaft 233 can maintain high-precision coaxiality and small radial runout during rotation.

[0066] Specifically, the upper shell 211 is provided with an upper through hole 2113 and a mounting groove 2114, the mounting groove 2114 surrounds the upper through hole 2113, the bearing 24 is fixed in the mounting groove 2114, the motor connecting head 231 of the connector 23 passes through the upper through hole 2113 and is connected with the motor 12, and the gear part 232 of the connector 23 is connected with the reduction box 22 in the mounting space 213 of the shell 21. The lower shell 212 is provided with a lower through hole 2124, the output connecting head 222 of the reduction box 22 passes through the lower through hole 2124 and is connected with the face knife.

[0067] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
