Description

Technical Field

[0001] The utility model belongs to the technical field of food slicers, and in particular relates to a self-cleaning food slicer. Background Art

[0002] A slicer is a machine that cuts thin and uniform tissue slices. The tissue is supported by hard paraffin or other materials. Each time it is cut, the slicer automatically advances the required distance (toward the direction of the knife) by the slicer thickness gauge. The gradient of the thickness gauge is usually 1 micron. When cutting paraffin-embedded tissue, multiple slices of slices are made due to adhesion to the wax edge of the previous slice. A food slicer is a device widely used in the catering industry and home kitchens. It is mainly used to cut various foods (such as vegetables, fruits, and meat) into uniform slices or strips. Traditional food slicers usually consist of several key components: a rotary drive mechanism, a blade, a fixed bracket, and a chip tray. Among them, the rotary drive mechanism usually includes a motor and a transmission assembly to drive the blade to rotate; the blade is the core component of the slicer and is used to cut food; the fixed bracket is used to support the rotary drive mechanism and the blade; the chip tray is located below the blade to collect food residues generated during the cutting process.

[0003] Traditional food slicers still have some shortcomings. First, since a large amount of food residue is generated during the cutting process, these residues are easy to adhere to the blade, which not only affects the cutting effect, but also increases the difficulty of cleaning. Secondly, traditional food slicers often require manual disassembly and cleaning of the blade, which is not only time-consuming and labor-intensive, but also has unsatisfactory cleaning effects for some hard-to-reach areas. Finally, after long-term use, food residue on the blade may breed bacteria, affecting food safety. Utility Model Content

[0004] In view of this, the utility model provides a self-cleaning food slicer, which solves the problem that residues are easily adhered to the blade during the cutting process of the traditional food slicer, and reduces the difficulty of cleaning by designing a concave and convex staggered cutting edge.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a self-cleaning food slicer, comprising a fixed bracket, the fixed bracket comprising a base and a support frame, the base being fixedly connected to the support frame, wherein the fixed bracket is used to support a rotary drive mechanism, the rotary drive mechanism is arranged on the support frame, the rotary drive mechanism comprises a motor and a transmission assembly, the rotary drive mechanism is used to drive a cutting member to rotate, the cutting member is provided with at least one cutting edge with staggered concave and convex portions, the cutting edge comprises a series of alternately arranged raised portions and recessed portions, the raised portions and the recessed portions are distributed along the circumference of the cutting member;

[0007] It also includes a crumb tray, which is arranged at the bottom of the fixed bracket in the travel direction and is used to receive food residues cut by the cutting member.

[0008] The raised parts and the recessed parts are arranged alternately along the circumference of the blade to form a staggered cutting edge. Each raised part is closely connected with the adjacent recessed part to form a continuous cutting edge, ensuring continuity and stability during the cutting process.

[0009] The technical effect of the self-cleaning food slicer provided by the utility model is as follows: the transmission assembly is used to transmit the power of the motor to the blade. The utility model adopts a concave-convex staggered cutting edge design to reduce the adhesion of food residues, thereby improving the self-cleaning performance of the food slicer and reducing maintenance costs.

[0010] On the basis of the above technical solution, the self-cleaning food slicer of the utility model can also be improved as follows:

[0011] Wherein, a rotating shaft is provided at the center of the cutting piece, the cutting piece is located at the central position of the supporting frame, and the rotating shaft passes through the supporting frame and is connected to the transmission assembly.

[0012] Furthermore, the height of the protrusion is greater than the depth of the recess, and the distance between adjacent protrusions and recesses is less than the minimum cutting thickness of the cutting element.

[0013] The beneficial effect of adopting the above-mentioned improvement scheme is: by controlling the height and depth ratio of the protrusion and the recess, the cutting edge can cut food more effectively, while reducing the adhesion of food residues, thereby improving the cutting efficiency and cleaning effect.

[0014] Furthermore, the transmission assembly includes a gear set, and the gear set is coaxially arranged with the cutting member.

[0015] Furthermore, the gear set includes a driving gear and a driven gear, the driving gear is fixedly connected to the output shaft of the motor, the driven gear is fixedly connected to the rotating shaft, and the driving gear and the driven gear transmit rotational power through gear meshing.

[0016] Furthermore, an annular baffle is also provided on the outer edge of the cutting piece, and the height of the annular baffle is greater than the height of the raised portion.

[0017] Furthermore, the apex of the protruding portion and the bottom of the recessed portion are both rounded, and the radius of the rounded corners is 0.5 mm to 2 mm.

[0018] The fillet processing refers to chamfering or arc transition processing of the apex and bottom to reduce stress concentration during cutting and extend the service life of the blade. The top of the raised part and the bottom of the recessed part are connected by a fillet transition to reduce stress concentration during cutting and extend the service life of the blade.

[0019] The transition area between the raised portion and the recessed portion is processed through a smooth transition, ensuring that food residues can be smoothly carried away by the water flow during the cutting process, thereby reducing the adhesion of food residues.

[0020] Furthermore, the ratio of the height of the protruding portion to the depth of the recessed portion is in a range of 1.1:1 to 1.5:1.

[0021] Furthermore, the chip tray is funnel-shaped, the opening of the chip tray faces the cutting piece, and the diameter of the opening is greater than the length of the cutting piece.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the crumb tray helps to collect food residues, simplifies the cleaning process, and reduces the impact of food residues on the equipment. The design of the funnel-shaped crumb tray allows food residues to flow into the crumb tray more smoothly, avoiding the blockage problem caused by residue accumulation.

[0023] Furthermore, the alternating convex and concave raised portions and concave recessed portions are in a shape of a triangle, a rectangle or a trapezoid, and the shape is specifically a longitudinal cross-sectional shape in a direction perpendicular to the rotation axis.

[0024] The choice of shape depends on the type and hardness of the food to be cut.

[0025] Compared with the prior art, the self-cleaning food slicer provided by the utility model has the following beneficial effects:

[0026] Reduce the adhesion of food residues:

[0027] The utility model effectively reduces the adhesion of food residues on the blade by designing a staggered concave-convex cutting edge. The staggered concave-convex cutting edge includes a series of alternately arranged convex parts and concave parts. This special shape design makes it difficult for food residues to adhere firmly to the blade, thereby greatly reducing the difficulty of cleaning;

[0028] Improve self-cleaning performance:

[0029] The utility model realizes the self-cleaning of the blade by the way of naturally removing the residue by water flow. When the blade rotates, the water flow can easily pass through the gaps between the concave and convex cutting edges to take away the food residue. This design not only reduces the cleaning time, but also reduces the maintenance cost;

[0030] Optimize cutting performance:

[0031] The staggered concave and convex cutting edges of the utility model are in the shape of triangle, rectangle or trapezoid, and the selection of these shapes helps to improve the cutting efficiency and ensure that the cut food slices are uniform. In addition, by controlling the height and depth ratio of the convex part and the concave part, the cutting performance is further optimized and the cutting accuracy is improved;

[0032] Extend blade life:

[0033] The utility model reduces stress concentration during cutting by rounding the apex of the raised part and the bottom of the recessed part, thereby extending the service life of the blade. This design reduces the wear of the blade in long-term use and reduces the frequency of replacement;

[0034] Improved security:

[0035] The blade of the utility model is made of stainless steel or hard alloy, which not only improves the wear resistance and corrosion resistance of the blade, but also ensures the safety of the food processing process. In addition, by limiting the thickness and diameter range of the blade, the stability of the blade during use is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0100] Specifically, the principle of the utility model is:

[0101] Concave and convex cutting edge design:

[0102] The core of the utility model lies in the design of the staggered concave and convex cutting edge. This design is achieved by a series of alternately arranged raised parts and recessed parts. The raised parts and recessed parts are distributed along the circumference of the blade, and the height of the raised parts matches the depth of the recessed parts to ensure that the adhesion of food residues is reduced during the cutting process.

The angle or radius R of the rounded corners is preferably 0.5 mm to 2 mm, which can be adjusted according to actual cutting requirements and blade material properties;

[0107] Cleaning principle:

[0108] The utility model realizes the self-cleaning of the blade by the way that water flow naturally removes the residue. During the cutting process, the water flow can pass through the gaps between the concave and convex cutting edges to take away the food residue. This design not only reduces the cleaning time, but also reduces the maintenance cost. The position of the spray device and the distance between the nozzle and the blade are also carefully designed to ensure that the cleaning liquid can be evenly sprayed on the blade, improving the cleaning efficiency;

[0109] Drive mechanism design:

[0110] The utility model adopts a stepper motor as the motor in the rotary drive mechanism. The stepper motor can provide precisely controlled rotary power, ensuring stability and accuracy during the cutting process. Through the use of a gear set, the smoothness and efficiency of power transmission are ensured, energy loss is reduced, and overall efficiency is improved;

[0111] Structural stability:

[0112] The fixed bracket of the utility model comprises a support frame and a base, and the structural strength of the support frame is increased by setting the reinforcing ribs, thereby improving the durability of the equipment. The support frame is fixedly connected to the base, and the rotating drive mechanism is arranged on the support frame, thereby ensuring the overall stability of the equipment.
