Description

Technical Field

[0001] The utility model relates to a kitchen cooking tool, and more specifically, to a drum cooking machine. Background Art

[0002] A drum cooking machine is a kitchen utensil that uses a rotating knife cylinder to cut or plane food ingredients, and is commonly used for cutting vegetables, shaving ice, etc. Existing drum cooking machines mainly consist of a base part, an outer cylinder part, a knife cylinder, etc. Its working principle is to drive the knife cylinder to rotate in the outer cylinder through the base part to cut food ingredients. The food ingredients are added from the feeding port at the upper part of the outer cylinder, and the food ingredients are pressed down to contact the cutting tools on the knife cylinder. As the knife cylinder rotates, the cutting of the food ingredients is achieved, and the cut food ingredients are discharged from one side of the knife cylinder, which has the advantages of convenient use, safety and high efficiency.

[0003] For the convenience of cleaning and replacement, existing drum cooking machines often adopt a detachable design to realize the disassembly and assembly between the base, the outer cylinder and the knife cylinder. However, most of the disassembly and assembly structures of existing drum cooking machines adopt locking nuts or snap-fit structures, and the structural design is relatively complex, and the disassembly and assembly operations are not very convenient. Chinese Patent No. ZL202321492730.9 discloses "A drum vegetable cutter knife cylinder disassembly and assembly structure and a drum vegetable cutter" (the authorization announcement date is March 29, 2024). Its drum vegetable cutter includes a base, a vegetable cutting cylinder and a knife cylinder. The base has a vertical part with a through hole, and a plug is provided on the side wall of the vertical part. A slot is provided at the tail of the outer cylinder, and the slot is adapted to the plug. The vegetable cutting cylinder and the base are connected together by the insertion and engagement of the slot and the plug. During assembly, first insert the vegetable cutting cylinder downward along the Z-axis direction on the base so that the slot is snapped onto the plug. At this time, the shaft hole corresponds to the through hole on the base; then insert the knife holder shaft of the knife cylinder along the X-axis direction into the shaft hole and the through hole. At this time, the vegetable cutting cylinder is completely restricted on the base. During disassembly, only the knife cylinder needs to be disassembled first, and then the vegetable cutting cylinder can be pulled off the base. This design can facilitate the disassembly and assembly of the base, the vegetable cutting cylinder and the knife cylinder, but there are also some problems that need to be improved:

[0004] ① The knife cylinder needs to have a relatively long knife holder shaft to pass through the vegetable cutting cylinder and insert into the base to achieve transmission, which makes the structure of the knife cylinder relatively complex. And the knife cylinder belongs to a vulnerable part and a replaceable part, so the cost of the knife cylinder is increased;

[0005] ② During disassembly and assembly, the vegetable cutting cylinder and the knife cylinder need to be disassembled and assembled separately, increasing the risk of exposure of the knife cylinder. Summary of the Invention

[0055] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0056] [Example]

[0057] Combination Figures 1 to 3 As shown, a drum food processor of the present embodiment includes a base 100, an outer cylinder 200 and a knife cylinder 300, wherein a driving assembly 130 is provided in the base 100, and the driving assembly 130 has an output transmission member 130A for connecting the knife cylinder 300 and driving the knife cylinder 300 to rotate; the outer cylinder 200 is detachably mounted on the base 100, and the outer cylinder 200 is provided with a feeding cylinder 220 for feeding food for cutting or planing; the knife cylinder 300 is detachably arranged in the outer cylinder 200, and the knife cylinder 300 is provided with a cutting tool, and the driving assembly 130 drives the knife cylinder 300 to rotate to realize the processing of the food. Importantly, a rotatable transmission shaft 210A is also provided on the outer cylinder 200, and the transmission shaft 210A is retained on the outer cylinder 200. A transmission part 300A is provided at the rear end of the knife cylinder 300. One end of the transmission shaft 210A can be connected to the transmission part 300A at the rear end of the knife cylinder 300 for transmission, and the other end of the transmission shaft 210A can be connected to the output transmission member 130A on the base 100 for transmission. That is, after the knife barrel 300 is installed in the outer cylinder 200, the transmission part 300A at the rear of the knife barrel 300 can be matched with the end of the transmission shaft 210A located on the inner side of the outer cylinder 200, so that the transmission shaft 210A can drive the knife barrel 300 to rotate together; after the outer cylinder 200 is installed on the base 100, the output transmission member 130A on the base 100 can be matched with the end of the transmission shaft 210A located on the outer side of the outer cylinder 200, so that the drive assembly 130 can drive the transmission shaft 210A to rotate, and then drive the knife barrel 300 to rotate in the outer cylinder 200. With the above design, the outer cylinder 200 and the knife barrel 300 can be disassembled together, reducing the risk of the knife barrel 300 being exposed and injured during the disassembly process, and the disassembly and assembly operation is simpler and more convenient; and the transmission structure of the knife barrel 300 can be simplified, the tool holder shaft structure is omitted, and the manufacturing cost of the knife barrel 300 is reduced.

[0058] As a preferred design, a spline structure is adopted for plug-in transmission connection between the transmission shaft 210A and the output transmission member 130A, and an axial spiral engagement structure is adopted for plug-in transmission connection between the transmission shaft 210A and the transmission part 300A. In this way, quick installation or disassembly can be achieved through the plugging and unplugging actions, the disassembly and assembly operations are convenient, and the transmission is stable and reliable. Specifically, the output transmission member 130A can adopt an internal spline hole, and the outer end of the transmission shaft 210A adopts a spline shaft. When the outer cylinder 200 and the base 100 are assembled, the outer end of the transmission shaft 210A can be inserted into the internal spline hole of the output transmission member 130A, and torque transmission is achieved through the internal and external splines; the transmission part 300A can be a through hole or a blind hole with internal spiral ribs, and the inner end of the transmission shaft 210A is a shaft head with external spiral ribs, and the tightening directions of the internal and external spiral ribs are consistent with the cutting rotation direction of the cutter cylinder 300. During the rotation of the cutter cylinder 300 driven by the transmission shaft 210A, the internal and external spiral ribs can automatically tighten to achieve torque transmission. Generally speaking, it is better that the spiral length of the internal and external spiral ribs is less than one turn, and the direct plugging and unplugging connection between the transmission shaft 210A and the cutter cylinder 300 can be realized. Refer to Figure 9 As shown, in order to facilitate the assembly of the transmission shaft 210A and the outer cylinder 200, the transmission shaft 210A can be composed of an inner shaft 210A1 and an outer shaft 210A2. The inner shaft 210A1 and the outer shaft 210A2 are in plug-in fit through non-circular shaft holes and are fixed with screws. A ring groove is formed by the combination of the outer sides of the inner shaft 210A1 and the outer shaft 210A2, and the hole wall of the outer cylinder 200 is located in the ring groove to realize the axial limit of the transmission shaft 210A on the outer cylinder 200, so that the transmission shaft 210A is kept on the outer cylinder 200.

[0059] As Figure 1 and Figure 3 As shown in, in order to ensure the firmness of the outer cylinder 200 on the base 100, a locking hook assembly 110 is provided on the base 100. The outer cylinder 200 is fixed on the base 100 through the locking hook assembly 110 and can be disassembled from the base 100 along the axis s after the locking hook assembly 110 is unlocked. The above-mentioned axis s can be referred to Figure 3 As shown, that is, the rotation axis direction of the cutter cylinder 300, which is also the rotation axis direction of the output transmission member 130A. The use of the locking hook assembly 110 ensures the connection firmness between the outer cylinder 200 and the base 100 and ensures the use reliability of the drum type cooking machine. Further refer to Figures 6 to 8As shown, in this embodiment, the above-mentioned hook assembly 110 includes a base 111, a hook 112, an elastic member 113, and an unlocking button 114. The base 111 is fixed to the inner side of the base 100. Specifically, during implementation, the base 111 can be fixedly installed on the outer shell of the base 100, or the base 111 can be fixed to the driving assembly 130 and fixed in the outer shell together with the driving assembly 130. This embodiment preferably adopts the latter to further facilitate the assembly of the base 100. The hook 112 is movably arranged on the base 111 and can slide in the chute of the base 111. The elastic member 113 acts between the hook 112 and the base 111, and the elastic member 113 can make the hook 112 have an elastic tendency to maintain the locked state. A compression spring is preferably used. The unlocking button 114 protrudes from the base 100 and faces the hook 112, so that the unlocking button 114 can be pressed, and the hook 112 can be driven to move through the pressing action to unlock. A jack 110A with an opening direction consistent with the axial direction of the output transmission member 130A is also provided on the base 111. The hook 112 is located behind the jack 110A, and a hook 212 is provided at the rear end of the outer cylinder 200. When the outer cylinder 200 is connected to the base 100, the hook 212 on the outer cylinder 200 passes through the jack 110A and is fastened to the hook 112. When the unlocking button 114 is pressed, the hook 112 releases the hook 212 so that the outer cylinder 200 can be disassembled. The structure of this hook assembly 110 is simple and compact, the locking reliability of the outer cylinder 200 is strong, and the unlocking operation is simple and convenient. The locking state of the hook 112 and the hook 212 can be referred to Figure 11 and Figure 12 As shown, chamfers are provided at the ends of both the hook 112 and the hook 212. When installing the outer cylinder 200, the outer cylinder 200 is inserted axially s into the output transmission member 130A until it is in place. At this time, the hook 212 at the rear end of the outer cylinder 200 is inserted into the base 100 from the jack 110A, and under the action of the chamfer, the hook 112 is pushed to compress the elastic member 113. When the hook 212 is inserted in place, the hook 112 buckles the hook 212 under the action of the elastic member 113, thereby fixing the outer cylinder 200 to the base 100. When it is necessary to disassemble the outer cylinder 200, only need to press the unlocking button 114. At this time, the hook 112 moves to release the hook 212, and the outer cylinder 200 can be pulled out along the axial s direction. In order to ensure the balance of the locking force, a set of hook assemblies 110 can be provided on both sides of the output transmission member 130A. Correspondingly, two hooks 212 are also provided at the rear end of the outer cylinder 200.

[0060] As Figures 4 to 8As shown, in this embodiment, the base 100 is further provided with a positioning groove 140. On both sides of the positioning groove 140, there are support platforms 160. The lower part of the outer cylinder 200 has a positioning bottom surface 211 adapted to the above-mentioned positioning groove 140. On both sides of the positioning bottom surface 211, there are side bottom surfaces 214 capable of cooperating with the corresponding support platforms 160. The shape of the positioning groove 140 is adapted to the shape of the positioning bottom surface 211. Generally speaking, the outer cylinder 200 is a straight cylinder or a conical cylinder structure. At this time, the positioning bottom surface 211 can be a cylindrical surface or a conical surface. Correspondingly, the positioning groove 140 is also an inwardly concave cylindrical surface or conical surface. The support platform 160 is a plane located at the upper edge of the positioning groove 140, and the side bottom surface 214 is also a plane located at the upper edge of the positioning bottom surface 211. The support platform 160 is parallel to the side bottom surface 214. In this way, by placing the positioning bottom surface 211 of the outer cylinder 200 into the positioning groove 140 of the base 100, the alignment of the axis of the outer cylinder 200 and the axis of the output transmission member 130A can be automatically achieved. The contact and cooperation between the support platform 160 and the side bottom surface 214 can limit the axial rotation of the outer cylinder 200. Therefore, the outer cylinder 200 can axially move on the base 100 along the sliding and guiding cooperation between the positioning bottom surface 211 and the positioning groove 140, and between the side bottom surface 214 and the support platform 160 for disassembly or assembly, further ensuring the tightness and integrity after the connection between the outer cylinder 200 and the base 100, and facilitating the disassembly and assembly operations of the outer cylinder 200. Further, as Figure 4 and Figure 8 shown, on the support platform 160, there is also a first limiting rib 161, and on the side bottom surface 214, there is also a second limiting rib 215. Both the first limiting rib 161 and the second limiting rib 215 are parallel or substantially parallel to the axial direction of the output transmission member 130A, and the first limiting rib 161 and the second limiting rib 215 are staggered from each other. When the outer cylinder 200 is inserted and pulled out along the axis s, the first limiting rib 161 and the second limiting rib 215 can play a guiding role. Especially when the outer cylinder 200 adopts a conical cylinder structure, the alignment of the transmission shaft 210A and the output transmission member 130A can be ensured by means of the first limiting rib 161 and the second limiting rib 215, facilitating the accurate installation of the outer cylinder 200.

[0061] Further combined with Figure 4 and Figure 8 shown, in this embodiment, the base 100 is further provided with a limiting post 150. The rear part of the outer cylinder 200 is provided with a limiting hole 213 corresponding to the position of the limiting post 150. The insertion direction of the limiting post 150 and the limiting hole 213 is the same as the axial direction of the output transmission member 130A. When the outer cylinder 200 is installed, the limiting post 150 can be inserted into the limiting hole 213, further ensuring the connection firmness between the outer cylinder 200 and the base 100. Preferably, two limiting posts 150 are provided. When installing the drive assembly 130, the limiting post 150 can be used as a screw fixing point, which is beneficial to ensuring the screw fixing strength.

[0062] As Figure 13 and Figure 14 shown, in this embodiment, the drive assembly 130 is preferably an integral assembly structure, that is, the drive assembly 130 is an integral module. The drive assembly 130 is integrally and fixedly installed inside the housing of the base 100, making the assembly of the base 100 simpler and more convenient, and facilitating the guarantee of the integrity of the base housing, reducing splicing seams, and improving the overall sealing performance and aesthetics of the base. Specifically, the housing includes an upper cover 170 and a bottom case 180. The drive assembly 130 is respectively provided with a vertical connection hole 136 and a horizontal connection hole 137. The upper cover 170 is respectively provided with a vertical screw post 171 corresponding to the position of the corresponding vertical connection hole 136 and a screw hole 150A corresponding to the position of the corresponding horizontal connection hole 137.
