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 slicing unit, mounted on the machine body, includes slicing blades for slicing the ingredients in the feeding hopper.

[0010] A dicing unit, disposed on the machine body, includes a dicing blade for dicing sliced ​​ingredients formed by slicing blades;

[0011] The slicing blade is a reciprocating slicing blade that slices during linear reciprocating motion. The reciprocating slicing blade has a flow channel for the sliced ​​ingredients formed during the slicing process to flow out. The dicing blade includes a dicing blade cylinder that can move with the reciprocating slicing blade and rotate about its own axis. The dicing blade cylinder can dice the sliced ​​ingredients flowing out from the sliced ​​ingredient flow channel.

[0012] To simplify the structure of the slicing blade and achieve a stable fit between the slicing blade and the dicing tube, the slicing blade 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 feeding hopper and an outlet side facing away from the feeding hopper. A sheet-like food channel is provided on the blade holder, extending from its infeed side to its outlet side. A slicing blade for slicing the food is provided in the sheet-like food channel. The dicing tube is a mesh structure with interconnected dicing holes distributed throughout. 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 sheet-like food channel, and during rotation, it compresses the sheet-like food moving forward in the sheet-like food channel toward the outlet side of the blade holder, thereby forming diced food inside the dicing tube.

[0013] In order to enable the knife holder to smoothly slice the food in the feeding hopper during linear movement, the knife holder is divided into a first plate and a second plate with the sliced ​​food channel as the boundary. The slicing knife is located on the first plate, and the blade of the slicing knife is located on the feeding side of the first plate and exposed on the side of the feeding hopper relative to the feeding side of the second plate.

[0014] To ensure that the sliced ​​ingredients formed during the slicing process can move smoothly 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 gap between the first guide wall and the guide wall forms the channel for the sliced ​​ingredients.

[0015] 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 this first guide wall constitutes the slicing blade. It is conceivable that the slicing blade could also be a separate component independent of the blade holder body, such as a separate component that can be connected to the blade holder body by screws.

[0016] In order to effectively cut the food in the feeding hopper during the reciprocating movement of the blade holder, 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 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.

[0017] 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 sliced ​​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.

[0018] As an improvement, the blade holder is horizontally positioned and extends in the left-right direction, the sliced ​​food channel is arranged in the front-back direction of the blade holder, the axis of the dicing blade tube extends in the front-back direction, and the peripheral wall of the dicing blade tube has a notch opened along its axial direction, which forms a second discharge port for diced food to flow out.

[0019] The horizontal design of the blade holder ensures that all parts of the slicing blade can cut the food, extending the life of the slicing blade. In addition, the non-closed structure with notches in the dicing tube allows the diced food cut by the dicing tube to flow out quickly from the tube, reducing residue problems.

[0020] In order to achieve smooth dicing during the feeding of sheet-like ingredients, the tangential direction of the part of the dicing blade corresponding to the outlet of the sheet-like ingredient channel in its rotation direction is denoted as the first direction, and the moving direction of the sheet-like ingredients in the sheet-like ingredient channel is denoted as the second direction. The angle between the first direction and the second direction is an acute angle.

[0021] The above structural design allows the dicing tube to assist in discharging sliced ​​ingredients during rotation, ensuring that the slicing and dicing processes proceed smoothly in a certain forward direction. This avoids the problem of food accumulation at the exit of sliced ​​ingredients and also guarantees the dicing effect to a certain extent, resulting in more plump diced ingredients.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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:

[0027] A drive motor is mounted on the machine body;

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Compared with existing technologies, the advantages of this invention are as follows: The food is sliced ​​using a linearly moving blade holder, and during the slicing and unloading process (unloading from the sliced ​​food channel), the rotating dicing tube, in conjunction with the blade holder, dices the sliced ​​food. This dicing method ensures that each slice is promptly diced, preventing accumulation. The slicing and dicing processes are sequential, resulting in a smoother cutting process. Furthermore, since only single slices are diced, the dicing tube is less prone to deformation, and the sliced ​​food is less likely to be damaged by prolonged compression as in existing technologies.

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] 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.

[0044] Example 1

[0045] See Figures 1-7 The diagram shows a dicing machine, including a body 10, a slicing unit, a dicing unit, a power transmission mechanism, and a drive mechanism disposed within the body 10.

[0046] The machine body 10 is generally cuboid in shape, with a working chamber 12 defined inside. The working chamber 12 houses the aforementioned slicing 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 blade cylinder 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.

[0047] The slicing unit includes a slicing knife 2310 for slicing the ingredients in the feeding hopper 11.

[0048] The slicing blade 2310 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.

[0049] In this embodiment, the blade 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 blade 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, basically perpendicular to the moving direction of the blade 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 has a first guide wall 231 extending forward and inclined toward the side where the second side 222 is located. The second side 222 of the strip-shaped opening 22 has a second guide wall 232 extending backward and inclined toward the side where the first side 221 is located. The gap between the first guide wall 231 and the guide wall forms a sheet-like food channel 213 for the sliced ​​food to pass through. Figure 6 As can be seen, the sheet-like food channel 213 extends from front to back to the right. The first guide wall 231 has a blade at its edge away from the main body of the blade holder 21. Therefore, the first guide wall 231 constitutes a slicing blade 2310 for cutting the food in the feeding hopper 11.

[0050] In this embodiment, the knife holder 21 is divided into a first plate 24 and a second plate 25, with the sheet-like food channel 213 as the boundary. The blade of the first guide wall 231 on the first plate 24 is exposed on the side of the wall facing the feeding hopper 11 relative to the feeding side of the second plate 25.

[0051] 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 3 It 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.

[0052] 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.

[0053] The dicing unit includes a dicing blade for dicing sliced ​​ingredients formed by slicing blade 2310.

[0054] The dicing tool includes a dicing blade cylinder 31. The dicing blade cylinder 31 has a mesh structure with dicing mesh holes 32, which are interconnected internally and externally. Dicing blades are formed on the outer peripheral wall of the dicing blade cylinder 31. In this embodiment, the outer peripheral wall of the dicing blade cylinder 31 is a closed cylindrical structure in the circumferential direction. Specifically, the dicing blade cylinder 31 is mounted on a blade holder 21 and can reciprocate in the left-right direction with the blade holder 21. Furthermore, the axis of the dicing blade cylinder 31 extends vertically, allowing it to rotate around its own axis. More specifically, the dicing blade cylinder 31 is located at the outlet of the sheet-like food channel 213, and during rotation, it compresses the sheet-like food moving forward in the sheet-like food channel 213 towards the discharge side 212 of the blade holder 21, thereby forming diced food inside the dicing blade cylinder 31.

[0055] 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 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 has an open structure, which forms the first discharge port 331 for the diced ingredients inside to flow out. 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.

[0056] 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 sliced ​​food channel 213 in its rotational direction is denoted as the first direction A1, and the direction of movement of the sliced ​​food within the sliced ​​food 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. This allows the dicing tube 31 to assist in the discharge of sliced ​​food during rotation, ensuring that the slicing and dicing processes proceed smoothly along a certain forward direction. This avoids food accumulation at the outlet of the sliced ​​food and, to a certain extent, guarantees the dicing effect, resulting in more plump diced pieces.

[0057] 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.

[0058] In this embodiment, the ingredient is sliced ​​using a linearly moving blade holder 21. During the slicing and discharging process (discharging from the sliced ​​ingredient channel 213), the rotating dicing tube 31, in conjunction with the blade holder 21, dices the sliced ​​ingredient. This dicing method ensures that each slice is promptly diced, preventing accumulation. The slicing and dicing processes proceed sequentially, resulting in a smoother dicing operation. Furthermore, since only single slices are diced, the dicing tube 31 is less prone to deformation, and the sliced ​​ingredient is less likely to be damaged by prolonged compression as in existing technologies.

[0059] Example 2

[0060] See Figures 8-10 Another dicing machine is shown. The difference between the dicing machine in this embodiment and the dicing machine in Embodiment 1 is that the blade holder 21 is horizontally arranged and extends in the left-right direction. Correspondingly, the axis of the dicing blade cylinder 31 extends front-back. Furthermore, the dicing blade cylinder 31 has a non-enclosed cylindrical structure, as detailed below:

[0061] The feeding hopper 11 is located at the top of the machine body 10 and extends vertically. The two limiting slide grooves 13 on the machine body 10 are arranged opposite each other in the front-rear direction and both extend in the left-right direction. The two opposite sides of the tool holder 21 in the front-rear direction are correspondingly slidably constrained in the two limiting slide grooves 13 in the front-rear direction of the machine body 10.

[0062] The sliced ​​food channel 213 on the blade holder 21 is also arranged in the front-to-back direction of the blade holder 21. Specifically, the sliced ​​food channel 213 slopes to the right from top to bottom. The dicing blade tube 31 is also located at the outlet of the sliced ​​food channel 213, and its axis extends front-to-back. More specifically, the dicing blade tube 31 has a notch on its peripheral wall that forms a second discharge port 332 for diced food to flow out. Figure 10As shown, the outer peripheral wall of the dicing tube 31 corresponds to a circle with a center of 180 degrees, meaning its cross-section is a semi-circular arc structure. In this embodiment, the horizontal arrangement of the blade holder 21 ensures that all parts of the slicing blade 2310 can cut the food, extending the service life of the slicing blade 2310. Furthermore, by setting the dicing tube 31 as a non-closed structure with a notch, the diced food cut by the dicing tube 31 can flow out quickly from the dicing tube 31, reducing residue issues.

[0063] 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.
