Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a fruit and vegetable dicing machine. Background Technology

[0002] A fruit and vegetable dicing machine is used to cut fruits and vegetables into cubes or chunks. Generally speaking, the processing steps for dicing fruits and vegetables are to first cut the ingredients into slices, then cut the slices into strips, and then cut them into cubes, or directly cut the slices into cubes.

[0003] For example, Chinese invention patent application CN201821944001.1 (authorization announcement number: CN209063156U) discloses a food dicing device, including a shell with a rectangular cavity. Inside the shell, there is a slicing knife group composed of several horizontally arranged long strip-shaped slicing blades arranged side by side. The slicing knife group divides the rectangular cavity into two smaller rectangular cavities. The cavity in which the slicing blade blades face is the slicing cavity, and the other is the dicing cavity. The gaps between adjacent slicing blades and between the outermost slicing blade and the inner wall of the shell constitute slicing outlets. The slicing outlets connect the slicing cavity and the dicing cavity. All slicing outlets are of uniform size. On the bottom surface of the dicing cavity, there is a dicing knife group composed of several intersecting dicing blades. After slicing the food in the slicing cavity, the food enters the dicing cavity to complete the dicing. During the cutting and preparation process, the ingredients are placed into the inlet, and the slicing pusher is pushed so that the slicing pusher block of the slicing pusher enters the slicing blade assembly to cut the ingredients into slices. Then, the slices smoothly enter the dicing chamber, and the dicing pusher is pressed down so that the dicing pusher block of the dicing pusher enters the dicing blade assembly to cut the sliced ​​ingredients into diced pieces. Finally, the diced pieces are smoothly pushed out from the outlet below.

[0004] The dicing device in the aforementioned patent application has certain shortcomings. This dicing device cuts the food into multiple stacked slices at once using a slicing blade assembly, and then pushes the dicing block to cut the stacked slices into diced pieces at once using the dicing blade assembly. Because multiple layers of sliced ​​food are diced at once, the dicing process has high resistance, requires a large force, and the pressure time on the food is relatively long. As a result, the food is easily damaged by severe compression (e.g., the part of the food in contact with the dicing cone is crushed), affecting the dicing effect. On the other hand, if the dicing blade assembly itself is not strong enough, it is also easy to deform, affecting its dicing effect. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a fruit and vegetable dicing machine that provides a smooth cutting process and is less likely to damage the ingredients due to excessive pressure, in light of the current state of the technology.

[0006] The technical solution adopted by this invention to solve the technical problem is as follows:

[0007] A fruit and vegetable dicing machine, comprising:

[0008] The machine body has a feeding hopper;

[0009] A shredding unit, mounted on the machine body, includes shredding blades for shredding the ingredients in the feeding hopper.

[0010] A dicing unit, disposed on the machine body, includes a dicing blade for dicing strips of food formed by a shredding blade;

[0011] The shredding blade is a reciprocating shredding blade capable of shredding during linear reciprocating motion. The reciprocating shredding blade has a strip-shaped food channel for the strip-shaped food formed during the cutting process to flow out. The dicing blade includes a dicing blade cylinder that can move together with the reciprocating shredding blade and can rotate about its own axis. The dicing blade cylinder can dice the strip-shaped food flowing out from the strip-shaped food channel.

[0012] To simplify the structure of the shredder and achieve a stable fit between the shredder and the dicing tube, the shredder includes a plate-shaped blade holder that is slidably mounted on the machine body to move linearly relative to the machine body. The blade holder has an infeed side facing the hopper and an outlet side away from the hopper. A strip-shaped food channel extending from the infeed side to the outlet side is provided on the blade holder. A shredder blade for shredding the food is provided in the strip-shaped food channel. The dicing tube includes dicing blades arranged circumferentially and extending axially. The extension direction of the cross-section of each dicing blade is basically consistent with the radial direction of the dicing tube. The dicing tube is rotatably mounted on the blade holder to rotate around its own axis. The dicing tube is located at the outlet of the strip-shaped food channel and, during rotation, squeezes the strip-shaped food moving forward in the strip-shaped food channel toward the outlet side of the blade holder, thereby forming diced food inside the dicing tube.

[0013] To ensure that the strip-shaped ingredients formed during the slicing process can smoothly move to the dicing tube and be squeezed by the rotating dicing tube, the blade holder has a strip-shaped opening extending from its inlet side to its outlet side. The extension direction of the strip-shaped opening is basically perpendicular to the moving direction of the blade holder. The strip-shaped opening has a first side and a second side opposite to each other in the moving direction of the blade holder. The first side of the strip-shaped opening is provided with a first guide wall extending towards the inlet side of the blade holder and inclined towards the side where the second side is located. The second side of the strip-shaped opening is provided with a second guide wall extending towards the outlet side of the blade holder and inclined towards the side where the first side is located. The inner wall of the first guide wall also has cutting blades arranged sequentially at intervals along the extension direction of the strip-shaped opening. Each cutting blade extends from the inner wall of the first guide wall towards the second guide wall and connects with the inner wall of the second guide wall, thereby dividing the gap between the first guide wall and the second guide wall into multiple slicing channels. All the slicing channels together constitute the strip-shaped ingredient channel.

[0014] To simplify the structure of the blade holder, the first guide wall has a cutting edge at its edge away from the blade holder body, and each of the cutting blades also has a cutting edge at its edge facing the feed side of the blade holder. The first guide wall and the cutting blades together constitute the shredder. It is conceivable that the shredder could also be a separate component independent of the blade holder body, such as one that can be connected to the blade holder body via screws.

[0015] In order to effectively cut the food in the feeding hopper during the reciprocating movement of the blade holder, the blade holder is divided into a first plate and a second plate with the strip-shaped food channel as the boundary. The blade holder also includes an auxiliary guide plate located on the feeding side of the second plate and extending along the moving direction of the blade holder. The side of the auxiliary guide plate adjacent to the strip-shaped opening of the blade holder is in contact with the blade of the first guide wall. The auxiliary guide plate is always in contact with the outer periphery of the outlet of the feeding hopper during the movement of the blade holder.

[0016] As an improvement, in order to facilitate the rapid flow of diced ingredients cut by the dicing tube out of the dicing tube and reduce residue problems, the blade holder is set vertically and extends in the left and right direction, the strip-shaped ingredient channel is arranged in the up and down direction of the blade holder, the axis of the dicing tube extends vertically, and the bottom opening of the dicing tube forms the first discharge port for the diced ingredients to flow out.

[0017] In order to achieve smooth dicing during the discharge of strip-shaped ingredients, the tangential direction of the part of the dicing tube corresponding to the outlet of the strip-shaped ingredient channel in its rotation direction is denoted as the first direction, and the movement direction of the strip-shaped ingredients in the shredding channel is denoted as the second direction. The angle between the first direction and the second direction is an acute angle.

[0018] The above structural design allows the dicing tube to assist in the discharge of strip-shaped ingredients during rotation, enabling the shredding and dicing processes to proceed smoothly in a certain forward direction. This avoids the problem of food accumulation at the outlet of strip-shaped ingredients and also ensures the dicing effect to a certain extent, making the diced ingredients more plump.

[0019] Generally, the linear movement of the blade holder and the rotational movement of the dicing cylinder can be driven by two independent drive mechanisms. However, to reduce the number of drive mechanisms and thus make the overall size of the fruit and vegetable dicing machine more compact, a mechanism is also provided between the machine body and the dicing cylinder to convert the linear movement of the blade holder relative to the machine body into the rotational movement of the dicing cylinder. power Transmission mechanism.

[0020] The power transmission mechanism can adopt various existing technologies such as gear and rack transmission mechanism and slider linkage mechanism. However, in order to simplify the power transmission mechanism and ensure the stability of power transmission, the machine body is also provided with a rack whose extension direction is consistent with the moving direction of the blade holder. The dicing blade cylinder is also coaxially connected with a transmission gear. The transmission gear is connected to the rack, thus forming the power transmission mechanism.

[0021] To mount the dicing blade on the blade holder and ensure its stable rotation, the blade holder is provided with a first connecting plate and a second connecting plate corresponding to the two ends of the dicing blade. The first end of the dicing blade has a connecting shaft extending axially along the dicing blade, and the connecting shaft is rotatably connected to the first connecting plate. The transmission gear is correspondingly connected to the connecting shaft. The second end of the dicing blade is rotatably connected to the second connecting plate, and the second connecting plate has an opening at a position corresponding to the opening at the second end of the dicing blade.

[0022] Normally, the reciprocating movement of the blade holder and the rotation of the dicing blade cylinder can be driven manually. However, in order to automate the above-mentioned actions and improve the user experience, a drive mechanism is also included to move the blade holder relative to the machine body.

[0023] The drive mechanism can be any existing technology, such as a drive motor coupled with a crank-sliding mechanism, a drive motor coupled with a worm gear transmission mechanism, or an electric push rod. The drive mechanism includes:

[0024] A drive motor is mounted on the machine body;

[0025] The swing arm has its first end connected to the output shaft of the drive motor and its second end connected to the tool holder. Driven by the drive motor, the second end of the swing arm swings around the output shaft of the drive motor and drives the tool holder to reciprocate in a straight line.

[0026] In order to match the swing arm with the tool holder during the rotational motion and avoid interference, the tool holder has a strip-shaped movable groove whose extension direction is at an angle to the moving direction of the tool holder, and the second end of the swing arm has a pin, which is slidably disposed in the strip-shaped movable groove.

[0027] To ensure the stability of the tool holder's linear movement relative to the machine body, the machine body has two limiting grooves arranged opposite each other in the vertical direction and extending in the same direction as the tool holder's movement. The two opposite sides of the tool holder in the vertical direction are respectively slidably constrained in the two limiting grooves.

[0028] Compared with existing technologies, the advantages of this invention are as follows: The food is shredded using a linearly moving blade holder, and during the shredding process (discharging from the strip-shaped food channel), the rotating dicing blade barrel, in conjunction with the blade holder, dices the strip-shaped food. This dicing method ensures that each strip-shaped food formed from shredding is promptly diced, preventing the accumulation of shredded food. The shredding and dicing processes are performed sequentially, resulting in a smoother dicing operation. Furthermore, since only single-piece (thin) food is diced, the dicing blade barrel is less prone to deformation, and the strip-shaped food is not damaged by prolonged compression as in existing technologies.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0037] See Figures 1-6 The diagram shows a dicing machine, including a body 10, a shredding unit, a dicing unit, a power transmission mechanism, and a drive mechanism disposed within the body 10.

[0038] The machine body 10 is generally cuboid in shape, with a working chamber 12 defined inside. The working chamber 12 houses the aforementioned shredding unit, dicing unit, power transmission mechanism, and drive mechanism. A feeding hopper 11 is located on the side (specifically the front) of the machine body 10. In this embodiment, the feeding hopper 11 extends upwards from the front of the machine body 10, and its bottom outlet communicates with the working chamber 12. The bottom of the machine body 10 has an opening, allowing the diced ingredients cut into cubes within the dicing tube 31 to fall. Support plates are located on the left and right sides of the bottom of the machine body 10 in this embodiment, meaning the main body of the machine body 10 is at a certain distance from its placement plane. When using the dicing machine, a serving tray can be placed directly below the bottom opening of the machine body 10 to collect the diced ingredients.

[0039] The shredding unit includes a shredding blade for shredding the ingredients in the feeding hopper 11.

[0040] The slicing blade includes a blade holder 21 that is generally plate-shaped. In this embodiment, the blade holder 21 is vertically arranged and extends in the left-right direction. In this embodiment, the blade holder 21 is slidably mounted on the machine body 10 in the left-right direction. Specifically, the machine body 10 has two limiting grooves 13 arranged opposite each other in the vertical direction and extending in the left-right direction near the outlet of the feeding hopper 11. Correspondingly, the two opposite sides of the blade holder 21 in the vertical direction are slidably constrained in the two limiting grooves 13.

[0041] In this embodiment, the tool holder 21 has a feeding side 211 (i.e., the front side) facing the feeding hopper 11 and a discharging side 212 (i.e., the rear side) away from the feeding hopper 11. Specifically, the tool holder 21 has a strip-shaped opening 22 extending from its feeding side 211 to its discharging side 212. The extension direction of the strip-shaped opening 22 is vertical, that is, it is basically perpendicular to the moving direction of the tool holder 21. The strip-shaped opening 22 has a first side 221 and a second side 222 opposite to each other in the left-right direction. The first side 221 of the strip-shaped opening 22 is provided with a first guide wall 231 that extends forward and is inclined toward the side where the second side 222 is located. The second side of the strip-shaped opening 22... A second guide wall 232 is provided at edge 222, extending rearward and inclined towards the side where the first side edge 221 is located. The inner wall of the first guide wall 231 also has cutting blades 233 arranged sequentially at intervals along the extension direction of the strip-shaped opening 22. Each cutting blade 233 extends from the inner wall of the first guide wall 231 towards the second guide wall 232 and connects with the inner wall of the second guide wall 232. Specifically, the extension direction of each cutting blade 233 is substantially perpendicular to the extension direction of the strip-shaped opening 22. Each cutting blade 233 divides the gap between the first guide wall 231 and the second guide wall 232 into multiple slicing channels 213. These slicing channels together constitute a strip-shaped food passage for the strip-shaped food formed during the cutting process.

[0042] pass Figure 6 As can be seen, each slicing channel 213 extends from front to back to the right. The first guide wall 231 has a cutting edge at the edge away from the main body of the blade holder 21, and each cutting blade 233 also has a cutting edge at the edge facing the feed side 211 of the blade holder 21. The first guide wall 231 and each cutting blade 233 together constitute the slicing blade of this embodiment.

[0043] In this embodiment, the blade holder 21 is divided into a first plate 24 and a second plate 25, with the strip-shaped food channel as the boundary. The blades of the first guide wall 231 and each cutting blade 233 are exposed on the side of the second plate 25 facing the feeding hopper 11.

[0044] In this embodiment, the tool holder 21 further includes an auxiliary guide plate 26 located on the feed side 211 of the second plate 25 and extending along the moving direction of the tool holder 21. The auxiliary guide plate 26 protrudes forward against the front sidewall of the first body, and the side of the auxiliary guide plate 26 adjacent to the strip-shaped opening 22 of the tool holder 21 is in contact with the cutting edge of the first guide wall 231. Figure 3It can be seen that the side wall of the machine body 10 connected to the feeding hopper 11 is a flat plate structure. The front side wall of the auxiliary guide plate 26 is in contact with the side wall of the outlet of the feeding hopper 11 on the machine body 10. Furthermore, the auxiliary guide plate extends long enough in the left and right directions, so that the auxiliary guide plate can always be in contact with the outer periphery of the outlet of the feeding hopper 11 during the movement of the tool holder 21.

[0045] The drive mechanism of this embodiment includes a drive motor 41 and a swing arm 42. The drive motor 41 is fixed to the machine body 10, and its output shaft extends back and forth. The first end of the swing arm 42 is connected to the output shaft of the drive motor 41, and the second end is connected to the strip-shaped movable groove 28 on the tool holder 21 via a pin 421. The extension direction of the pin 421 on the second end of the swing arm 42 is parallel to the extension direction of the output shaft of the drive motor 41. The strip-shaped movable groove 28 on the tool holder 21 is located on the left side and extends vertically. The pin 421 at the second end of the swing arm 42 is slidably disposed in the strip-shaped movable groove 28, wherein the outer diameter of the pin 421 is substantially the same as the width of the strip-shaped movable groove 28. Driven by the drive motor 41, the second end of the swing arm 42 swings around the output shaft of the drive motor 41, and drives the tool holder 21 to reciprocate in a linear direction via the pin 421.

[0046] The dicing unit includes a dicing blade for dicing strips of food that have been cut by a shredding blade.

[0047] The dicing tool includes a dicing tube 31. The dicing tube 31 includes dicing blades 311 arranged circumferentially and extending axially therein. The extension direction of the cross-section of each dicing blade 311 is substantially consistent with the radial direction of the dicing tube 311. The gap between two connected dicing blades 311 forms an internally and externally permeable dicing channel 32. Each dicing blade 311 has a dicing cutting edge at its outer edge. The upper ends of each dicing blade 311 are connected together by a closed fixing plate 312, and the lower ends of each dicing blade 311 are connected together by a fixing ring 313. That is, the upper end of the dicing tube 31 is closed, while the lower end is open, forming a discharge port 33.

[0048] The dicing tube 31 is mounted on the blade holder 21 and can reciprocate in the left-right direction with the blade holder 21. Furthermore, the axis of the dicing tube 31 extends vertically, allowing it to rotate around its own axis. More specifically, the dicing tube 31 is located at the outlet of the strip-shaped food channel, and during rotation, it compresses the strip-shaped food moving forward in the channel towards the outlet side 212 of the blade holder 21, thereby forming diced food inside the dicing tube 31.

[0049] The blade holder 21 has a first connecting plate 271 and a second connecting plate 272 at its two ends corresponding to the dicing blade cylinder 31. The first connecting plate 271 is located at the upper part, and the second connecting plate 272 is located at the lower part. Both the first connecting plate 271 and the second connecting plate 272 are plate structures extending rearward from the rear side of the blade holder 21. The fixing plate 312 at the first end of the dicing blade cylinder 31 has a connecting shaft 34 extending axially along the dicing blade cylinder 31. This connecting shaft 34 is rotatably connected to the first connecting plate 271 via a first bearing 451. The connecting shaft 34 of the dicing blade cylinder 31 passes upward through the first connecting plate 271 and is exposed. The exposed portion is connected to a transmission gear 44. The second end of the dicing blade cylinder 31 is rotatably connected to the second connecting plate 272 via a second bearing 452. Specifically, the second connecting plate 272 provides support for the dicing blade cylinder 31. Corresponding to the opening at the second end of the dicing tube 31, the second connecting plate 272 has an opening 2720 to allow diced ingredients to fall into the tube.

[0050] like Figure 6 As shown by the dotted lines, the tangential direction of the portion of the dicing tube 31 corresponding to the outlet of the strip-shaped food channel in its rotational direction is denoted as the first direction A1, and the direction of movement of the strip-shaped food in the shredding channel 213 is denoted as the second direction A2. The angle between the first direction A1 and the second direction A2 is an acute angle. Therefore, the dicing tube 31 can also assist in the discharge of the strip-shaped food during rotation, allowing the shredding and dicing processes to proceed smoothly in a certain forward direction, avoiding food accumulation at the outlet of the strip-shaped food, and to a certain extent ensuring the dicing effect, resulting in more plump diced food.

[0051] In this embodiment, the rotational movement of the dicing blade cylinder 31 and the linear movement of the blade holder 21 share the same drive mechanism. Specifically, the machine body 10 is provided with a rack 43 extending in the left-right direction, which meshes with the transmission gear 44 at the upper end of the dicing blade cylinder 31. During the left-right movement of the blade holder 21, the transmission gear 44 and the rack 43 engage in transmission, thereby converting the linear movement of the blade holder 21 relative to the machine body 10 into the rotational movement of the dicing blade cylinder 31. The aforementioned transmission gear 44 and rack 43 together constitute the power transmission mechanism of this embodiment.

[0052] In this embodiment, the cutting blade 21 moves linearly to shred the food. During the shredding process (discharging from the strip-shaped food channel), the rotating dicing blade 31, in conjunction with the blade 21, squeezes and dices the strip-shaped food. This dicing method ensures that each strip-shaped food is promptly diced, preventing the accumulation of shredded food. The shredding and dicing processes are performed sequentially, resulting in a smoother dicing operation. Furthermore, since only single pieces of food (thinner pieces) are diced, the dicing blade 31 is less prone to deformation, and the strip-shaped food is not damaged by prolonged compression as in existing technologies.

[0053] The term "transmission connection" as used in this invention refers to a direct connection between two components or an indirect connection through a transmission mechanism.
