Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, and more specifically to a dough knives and kitchen equipment. Background Technology

[0002] With the continuous improvement of people's living standards, dough mixers or stand mixers with dough-kneading functions are becoming increasingly widely used. However, existing dough mixers have a small contact area with the flour, making it difficult for the flour to form a dough and resulting in poor kneading effects. Furthermore, existing dough mixers are all designed for a single side. For example, Chinese Patent No. 202223079952.6 discloses a dough mixer including a main body with a blade shaft connecting seat on the left side. The main body has a first kneading blade and a second kneading blade, which tumble, lift, and squeeze the dough into a ball. However, this existing technology uses a single blade on the blade shaft connecting seat. During use, the same side of the blade must bear the burden of stirring the flour clumps and squeezing the dough, easily leading to fatigue and damage to the dough mixer, thus affecting its service life. Moreover, a single blade results in low kneading efficiency. Utility Model Content

[0003] In view of this, the present invention provides a dough-knife and kitchen equipment.

[0004] To achieve the above objectives, the first aspect of this utility model provides a dough-knife, comprising:

[0005] Connecting part;

[0006] Multiple stirring blades are disposed on the periphery of the connecting part and extend radially; the multiple stirring blades are distributed at different heights along the axial direction of the connecting part, and the projections of the multiple stirring blades on the horizontal plane form an included angle;

[0007] An extrusion sheet is disposed in the connecting part and extends along the axial direction of the connecting part. The side of the extrusion sheet opposite to the connecting part forms an extrusion working surface.

[0008] When the dough mixer blade of this technical solution rotates, multiple mixing blades stir water and flour at different heights, and the extrusion blade extrudes the dough, resulting in higher dough mixing efficiency. Furthermore, the multiple mixing blades and extrusion blades are distributed on the connecting part, and the projections of the mixing blades on the horizontal plane form an angle, meaning that the multiple mixing blades do not overlap in the axial direction of the connecting part. This effectively avoids the problem of fatigue damage caused by the load being concentrated on the same side of the dough mixer blade during mixing and extrusion, thus affecting the life of the dough mixer blade.

[0009] As a preferred embodiment of this utility model, the stirring blade is provided with a stirring working surface, at least one stirring blade has a stirring working surface that is concave in an arc shape, and at least one stirring blade has a stirring working surface that is convex in an arc shape. In this technical solution, the stirring working surface of one stirring blade is convex in an arc shape, which can reduce the resistance during stirring. The stirring working surface of one stirring blade is concave in an arc shape, which can push the dough towards the center of the connecting part during stirring, so as to better stir and compress the dough in the future.

[0010] As a preferred embodiment of this utility model, the stirring blade extends horizontally from the periphery of the connecting part, and the upper and lower surfaces of the stirring blade are flat. The upper and lower surfaces of the stirring blade play a certain role in pressing the dough to prevent the broken dough from suspending. Then, the extrusion plate compresses the broken dough into a ball.

[0011] As a preferred embodiment of this utility model, the plurality of stirring blades are distributed at least in the upper and lower parts of the connecting part, and the projections of the plurality of stirring blades on the horizontal plane are evenly distributed around the connecting part, effectively transferring the load on the stirring blades to the connecting part evenly.

[0012] In a preferred embodiment of this invention, at least two extrusion plates are provided. The thickness of the extrusion plates decreases from the side connected to the connecting part towards the extrusion working surface. The radial extension length of the extrusion plate beyond the connecting part is less than the radial extension length of the stirring blade beyond the connecting part. In this technical solution, the thickness of the extrusion plate decreases from the side connected to the connecting part towards the extrusion working surface, so the side of the extrusion plate is set as a slope or arc surface, which reduces the dough load to a certain extent. The radial extension length of the extrusion plate beyond the connecting part is less than the radial extension length of the stirring blade beyond the connecting part. If the extrusion plate is too long, it will push too much material to rotate. If the extrusion plate is shorter, the stirring blade can better stir the outer layer of flour. At the same time, the extrusion plate can also better extrude small lumps of dough into large dough balls, thereby improving the dough kneading efficiency.

[0013] As a preferred embodiment of the present invention, a mounting part is provided at the lower part of the connecting part, and the upper surface of the mounting part forms an inclined surface, which is inclined in a direction away from the upper part of the connecting part;

[0014] One of the extrusion pieces extends from the upper part of the connector to the inclined surface;

[0015] One of the extrusion plates is connected to a stirring blade at its top or bottom;

[0016] The two extrusion plates have different longitudinal heights.

[0017] This technical solution extrudes the dough from different heights and angles, effectively improving dough kneading efficiency.

[0018] As a preferred embodiment of this utility model, the connecting part is provided with an installation hole that penetrates the bottom and top surfaces of the connecting part; in this technical solution, the dough-making knife is installed in kitchen equipment such as dough mixers and food processors through the connecting part.

[0019] The second aspect of this utility model provides a kitchen appliance, including: a base and a steel pot, with a knife shaft installed inside the steel pot, and also including the aforementioned dough-kneading knife, which is mounted on the knife shaft.

[0020] As a preferred embodiment of this utility model, the inner wall of the steel pot is provided with baffles, which cooperate with the extrusion working surface of the extrusion plate. In this technical solution, gaps are formed between the baffles and the extrusion plate, as well as between the baffles and the stirring blade. When the dough knives rotate, the baffles will not interfere with the rotation of the dough knives. Furthermore, the dough is extruded more effectively through the cooperation between the baffles and the extrusion working surface of the extrusion plate.

[0021] As a preferred embodiment of this utility model, the upper end of the cutter shaft extends into the interior of the steel pot, and the lower end extends out of the bottom of the steel pot and is provided with an upper connector.

[0022] The base is equipped with a drive motor, a belt drive assembly and an output shaft. The drive motor drives the output shaft to rotate through the belt drive assembly.

[0023] The upper end of the output shaft is equipped with a lower connector. The upper connector and the lower connector cooperate to drive the cutter shaft to rotate.

[0024] The remaining beneficial technical effects of this utility model are embodied in the specific embodiments. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] For a dough kneading knife, please refer to [link / reference]. Figure 1-3 As shown, it includes:

[0037] Connecting part 100;

[0038] Multiple stirring blades 200 are disposed around the connecting part 100 and extend radially; the multiple stirring blades 200 are distributed at different heights along the axial direction of the connecting part, and the projections of the multiple stirring blades 200 on the horizontal plane form an angle;

[0039] An extrusion sheet 300 is disposed on the connecting portion 100 and extends along the axial direction of the connecting portion 100. An extrusion working surface 310 is formed on the side of the extrusion sheet 300 away from the connecting portion 100.

[0040] When the dough mixer blade rotates, the load on the mixing blade 200 and the extrusion blade 300 is distributed at different positions around the connecting part 100, which effectively avoids fatigue damage caused by concentrated load on the connecting part 100. When the mixing blade 200 rotates, water and flour are fully mixed at different heights, and the extrusion blade extrudes the formed dough, resulting in better dough-forming efficiency.

[0041] Specifically, the connecting part 100 can be as follows: Figure 1The device is cylindrical with a mounting part 110 at the bottom and a connecting part 100 connected to a driving component (such as a cutter shaft). The driving component drives the connecting part 100 and the mixing blade 200 and extrusion plate 300 located on the connecting part 100 to rotate. The mixing blade 200 mixes flour and water into small dough pieces, and then the extrusion plate 300 extrudes the mixed small dough pieces to form a large dough.

[0042] Furthermore, the connecting part 100 is integrally formed with the stirring blade 200 and the extrusion plate 300, or the connecting part 100 and the stirring blade 200 and the extrusion plate 300 are each independently manufactured and then assembled into one; and the connecting part 100 and the stirring blade 200 and the extrusion plate 300 can be made of metal or plastic.

[0043] Furthermore, multiple stirring blades 200 are distributed at different heights along the axial direction of the connecting part 100. During stirring, the multiple stirring blades 200 can efficiently and quickly mix flour and water to form small dough balls. Compared with the traditional single blade design, the stirring efficiency is higher. The projections of the multiple stirring blades 200 on the horizontal plane form an angle, so that the load on the multiple stirring blades 200 is distributed at different positions of the connecting part 100.

[0044] The extrusion plate 300 extends along the axial direction of the connecting part 100. Small dough balls at different height levels are extruded by the extrusion plate 300 and the inner wall of the container, which more effectively gathers and extrudes the small dough balls into a large dough ball.

[0045] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the dough mixer is equipped with three stirring blades 200, which are distributed at different heights on the connecting part 100, such as... Figure 3 As shown, the projections of the three stirring blades 200 on the horizontal plane form an angle, while two extrusion plates 300 are provided;

[0046] Optionally, in other embodiments, the number of stirring blades 200 can be increased to four, and the number of extrusion plates 300 can be set to two or three;

[0047] The arrangement of the stirring blade 200 and the extrusion plate 300 on the connecting part 100 ensures that the load acting on the stirring blade 200 and the extrusion plate 300 is evenly distributed on the connecting part 100 when the dough kneading knife rotates, preventing the connecting part 100 from being fatigued and damaged due to excessive force on one side or in one place.

[0048] In one embodiment, the stirring blade 200 is provided with a stirring working surface 210, at least one stirring blade 200 having a concave arc-shaped stirring working surface 210, and at least one stirring blade 200 having a convex arc-shaped stirring working surface 210, such as... Figure 3 As shown, it includes: a first stirring blade 201, a second stirring blade 202 and a third stirring blade 203. The dough knives are defined to rotate clockwise. The stirring working surfaces 210 of the first stirring blade 201 and the second stirring blade 202 are arranged in an arc-shaped concave shape, while the stirring working surface 210 of the third stirring blade 203 is arranged in an arc-shaped convex shape.

[0049] In one embodiment, the stirring blade 200 extends horizontally from the periphery of the connecting part 100. The upper and lower surfaces of the stirring blade 200 are planar. To a certain extent, the planar arrangement of the upper and lower surfaces of the stirring blade 200 can play a role in pressing the dough. After the broken dough is squeezed into a ball, during the continued stirring process, the dough is cut by the stirring blade 200 and then squeezed into a ball again by the extrusion plate 300. This process of cutting and squeezing into a ball is repeated, resulting in more uniform stirring and a more elastic dough.

[0050] In one embodiment, the plurality of stirring blades 200 are at least distributed in the upper and lower parts of the connecting portion 100, and the projections of the plurality of stirring blades 200 on the horizontal plane are evenly distributed around the connecting portion 100.

[0051] like Figure 2 As shown, the second stirring blade 202 is disposed on the upper part of the connecting part 100, the third stirring blade 203 is disposed on the lower part of the connecting part 100, and the first stirring blade 201 is disposed at about one-third of the height of the connecting part 100; and the included angle between the first stirring blade 201, the second stirring blade 202 and the third stirring blade 203 is 120°.

[0052] In one embodiment, at least two extrusion plates 300 are provided. The thickness of the extrusion plates 300 decreases from the side connected to the connecting part 100 toward the extrusion working surface 310, thereby reducing the surface load to a certain extent. The length of the extrusion plates 300 extending radially out of the connecting part 100 is less than the length of the stirring blades 200 extending radially out of the connecting part 100.

[0053] Furthermore, a mounting portion 110 is provided at the lower part of the connecting portion 100, and an inclined surface 111 is formed on the upper surface of the mounting portion 110, the inclined surface 111 being inclined in a direction away from the upper part of the connecting portion 100;

[0054] like Figure 3 As shown, the first extrusion piece 301 extends from the upper part of the connecting portion 100 to the inclined surface 111;

[0055] The top or bottom end of the second extrusion plate 302 is connected to a stirring blade 300;

[0056] The first extrusion sheet 301 and the second extrusion sheet 302 are arranged symmetrically about the axis of the connecting part 100, but the longitudinal heights of the first extrusion sheet 301 and the second extrusion sheet 302 are different, such as... Figure 1 As shown, the top of the second extrusion plate 302 is connected to the lower surface of the second stirring blade 202. The second extrusion plate 302 extends downward along the axial direction of the connecting part 100, but does not extend to the inclined surface 111.

[0057] When the dough kneading blade rotates, the first extrusion plate 301 and the second extrusion plate 302 extrude the dough at different angles.

[0058] Furthermore, the connecting part 100 is provided with a mounting hole 120, which penetrates the bottom and top surfaces of the connecting part 100. During installation, the driving component (i.e., the cutter shaft) is inserted into the mounting hole 120. The mounting hole 120 and the cutter shaft 510 are not cylindrical, so that the cutter shaft drives the dough kneading knife to rotate.

[0059] Kitchen equipment, such as Figure 4-7 As shown, it includes: a base 400 and a steel pot 500. The steel pot 500 is equipped with a knife shaft 510 and also includes the aforementioned dough kneading knife 00, which is mounted on the knife shaft 510.

[0060] Furthermore, the inner wall of the steel pot 500 is provided with baffles 530, which protrude toward the central axis of the steel pot 500. There is a gap between the baffles 530 and the extrusion working surface 310 of the extrusion plate 300. When the dough kneading blade 00 rotates, the baffles 530 will not interfere with the dough kneading blade 00. When the dough kneading blade 00 rotates, the baffles 530 cooperates with the extrusion working surface 310 of the extrusion plate 300, and the extrusion working surface 310 of the extrusion plate 300 and the inner wall of the steel pot 500 extrude the dough. The baffles 530 and the extrusion working surface 310 cooperate to further extrude the dough, resulting in a better extrusion effect.

[0061] The upper end of the cutter shaft 510 extends into the steel pot 500, and the lower end extends out of the bottom of the steel pot 500 and is provided with an upper connector 520. The base 400 is provided with a drive motor 410, a belt drive assembly 420 and an output shaft 430. The drive motor 410 drives the output shaft 430 to rotate through the belt drive assembly 420. The upper end of the output shaft 430 is provided with a lower connector 440, which cooperates with the upper connector 520 to drive the cutter shaft 510 to rotate.

[0062] Specifically, the belt drive assembly 420 has a pinion, a gear and a belt, the power shaft of the drive motor 410 is connected to the pinion, the output shaft 430 is connected to the gear, and the belt is connected between the pinion and the gear.

[0063] After the steel pot 500 is installed on the base 400, the upper connector 520 of the cutter shaft 510 is engaged with the lower connector 440 of the output shaft 430. The drive motor 410 sequentially drives the belt drive assembly 420, the output shaft 430, and the cutter shaft 510, and finally drives the dough kneading knife 00 to run, thus realizing the dough kneading function.

[0064] The bottom of the stainless steel cooker 500 is also equipped with a heating element, which can heat the food inside the cooker.

[0065] In addition, in this embodiment, the dough kneading blade 00 and the blade shaft 510 are detachably connected. When performing other functions, the dough kneading blade 00 can be removed and replaced with other types of blades to achieve other functions, such as replacing the stirring blade to achieve automatic cooking function, etc.

[0066] Furthermore, the kitchen equipment is equipped with a controller 600 on the base 400. The controller 600 is equipped with a touch screen display and can control the operation of the kitchen equipment, such as adjusting the rotation speed of the blade shaft 510 and adjusting the heating temperature of the heating element.

[0067] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
