[0073] Currently, the mixing bowls of dough mixers are generally installed by a snap-fit ​​mechanism, leaving users with no sense of whether the installation is correct. Furthermore, most current dough mixers only have a rotating dough hook while the mixing bowl remains stationary.

[0074] Based on this, the present invention provides a food processing machine, comprising:

[0075] A mixing bowl, used to hold ingredients;

[0076] The transmission seat is used to support and fix the dough bowl and drive the dough bowl to rotate.

[0077] The base is used to mount the transmission seat, and the transmission seat is rotatably mounted on the base;

[0078] The machine body assembly includes a lower machine body assembly connected to one end of the base and an upper machine body assembly that is flipped and movably connected to the lower machine body assembly. The upper machine body assembly includes a head positioned above the kneading bowl and a horizontal support arm extending from the head toward the lower machine body assembly. The head is configured as a mounting position for installing the kneading hook.

[0079] A dough hook is rotatably mounted on the head of the upper body assembly;

[0080] A transmission assembly is connected to the transmission base and the dough hook respectively, and is used to drive the transmission base and the dough hook to rotate.

[0081] The power component is connected to the transmission component and is used to drive the movement of the transmission component;

[0082] The dough bowl is detachably connected to the transmission base. The transmission base is equipped with a bowl locking component. When the dough bowl is installed in place, the bowl locking component prevents the dough bowl from loosening. The bowl locking component can be elastically extended and retracted along the line connecting the axis of the transmission base and the bowl locking component to facilitate the disassembly and assembly of the dough bowl.

[0083] There is a speed difference between the dough hook and the dough bowl.

[0084] This invention provides both tactile and auditory feedback to the dough bowl after it is installed, and also allows the dough hook and the dough bowl to rotate while creating a speed difference, resulting in better dough-forming and kneading effects.

[0085] The present invention will be described in detail below with reference to specific embodiments.

[0086] like Figure 1-19 As shown in the figure, this embodiment of a food processing machine can be a dough mixer, including a base 1, a body assembly 2, a dough mixing bowl 3, a dough blocking rod 4, a dough mixing hook 5, a transmission seat 6, a transmission assembly, and a power assembly 100.

[0087] In this embodiment, the mixing bowl 3 is used to hold ingredients, such as flour, egg liquid, and other ingredients. Specifically, the mixing bowl 3 includes a bottom with a peripheral wall, the peripheral wall including an open upper end through which ingredients can be introduced into the mixing bowl 3. The mixing bowl 3 has a diameter of approximately 24 cm and a height of approximately 17 cm, forming a volume of approximately 7 L.

[0088] In this embodiment, the transmission base 6 is used to support and fix the dough bowl 3 and drive the dough bowl 3 to rotate, and the dough bowl 3 is detachably connected to the transmission base 6. The transmission base 6 is provided with a bowl locking component. When the dough bowl 3 is installed in place, the bowl locking component prevents the dough bowl 3 from loosening. The bowl locking component can be elastically extended and retracted along the line connecting the axis of the transmission base 6 and the bowl locking component to facilitate the installation and removal of the dough bowl 3.

[0089] In this embodiment, the bottom of the mixing bowl 3 is provided with a bowl protrusion 301, and the bowl locking assembly includes a bowl locking groove 601, a bowl locking member 602, and a locking elastic member 603. The bowl locking groove 601 is disposed in the circumferential direction of the transmission base 6, and its length direction extends along the circumferential direction of the transmission base 6. The bowl protrusion 301 can move within the bowl locking groove 601. The bowl locking member 602 is radially movable on the outer wall of the bowl locking groove 601 and divides the bowl locking groove 601 into a locking space 604 and a moving space 605. One end of the locking elastic member 603 is fixedly disposed on the transmission base 6, and the other end is connected to the bowl locking member 602 to provide elasticity to the bowl locking member 602. Specifically, a positioning post is provided on the transmission base 6, and the locking elastic member 603 is sleeved on the positioning post, with one end fixedly abutting against the transmission base 6, and the other end abutting against the limiting groove opened on the end of the bowl locking member 602. When the dough bowl 3 is installed or removed, the bowl protrusion 301 pushes the bowl locking member 602 to move radially along the transmission seat 6, switching between the locking space 604 and the movement space 605.

[0090] In this embodiment, in order to facilitate the positioning and installation of the bowl protrusion 301 of the dough bowl 3, an avoidance groove 607 is connected to the side of the bowl locking groove 601 away from the locking space 604.

[0091] In this embodiment, to reduce noise, a transmission seat insert 606 is provided on the transmission seat 6, that is, a part is separated from the transmission seat 6. The transmission seat 6 and the transmission seat insert 606 can be made of different materials as needed. The cup locking groove 601 and the clearance groove 607 can both be provided on the transmission seat insert 606.

[0092] In this embodiment, the number of bowl locking components is ≥2, and the number of bowl protrusions 301 is the same as the number of bowl locking components. The more bowl locking components there are, the more stable the transmission seat 6 and the dough bowl 3 are during locking and rotating, and the less likely the dough bowl 3 is to wobble. Specifically, the number of bowl locking components can be 4, achieving a stable connection of the dough bowl 3.

[0093] When the mixing bowl 3 is installed, the mixing bowl 3 rotates relative to the transmission base 6, and the direction of rotation is the same as the direction of rotation of the transmission base 6 in the working state. In this embodiment, when the mixing bowl 3 is installed, the mixing bowl 3 rotates clockwise relative to the transmission base 6, and the direction of rotation of the transmission base 6 in the working state is also clockwise.

[0094] Specifically, when installing the kneading bowl 3, the bowl protrusion 301 of the kneading bowl 3 is inserted into the bowl locking groove 601 through the relief groove 607. The kneading bowl 3 is rotated clockwise, causing the bowl protrusion 301 to move to the bowl locking member 602 within the movement space 605. This pushes the bowl locking member 602 to slide outward and backward. After sliding to the limit position, as the kneading bowl 3 continues to rotate under force, the bowl protrusion 301 moves into the locking space 604 and locks. The bowl locking member 602 is reset by the elastic force of the locking elastic member 603.

[0095] When disassembling the mixing bowl 3, rotate the mixing bowl 3 counterclockwise. The bowl protrusion 301 of the mixing bowl 3 pushes the bowl locking member 602 to slide outward and backward. After sliding to the limit position, as the mixing bowl 3 continues to rotate under force, the bowl protrusion 301 moves into the movement space 605 and unlocks. The bowl locking member 602 is reset by the elastic force of the locking elastic member 603, and the mixing bowl 3 can be taken out through the relief groove 607.

[0096] The bowl locking component in this embodiment provides both tactile and audible feedback after the dough bowl 3 is installed in place, ensuring safe use.

[0097] In this embodiment, in order to reduce friction between parts, eliminate noise, and extend the service life of parts, a wear-resistant pad 608 is provided between the mixing bowl 3 and the transmission seat 6.

[0098] In this embodiment, the base 1 is used to mount the transmission seat 6, and the transmission seat 6 is rotatably mounted on the base 1.

[0099] In this embodiment, the body assembly 2 includes a lower body assembly 201 connected to one end of the base 1 and an upper body assembly 202 movably connected to the lower body assembly 201. The upper body assembly 202 includes a head positioned above the dough bowl 3 and a horizontal support arm extending from the head toward the lower body assembly 201. The head is configured as an installation position for mounting the dough hook 5.

[0100] This embodiment of the dough mixer has a first working state and a second working state. As the upper body assembly 202 flips relative to the lower body assembly 201, the dough mixer switches between the first and second working states. When the dough mixer is in the first working state, the upper body assembly 202 is in a horizontal position, and its head is positioned above the dough bowl 3. When the dough mixer is in the second working state, the upper body assembly 202 flips upward relative to the lower body assembly 201 and is in a raised position, and the dough bowl 3 can be removed from the transmission seat 6.

[0101] In this embodiment, the dough mixer also includes a locking device and an unlocking device. When the upper body assembly 202 is in a horizontal or raised position, the locking device automatically fixes the relative positions of the upper body assembly 202 and the lower body assembly 201. The unlocking devices are located on the sides of the upper body assembly 202, specifically one on each side in this embodiment, and are driven to allow the upper body assembly 202 to move from one position to another. Both the locking and unlocking devices are common technologies and will not be described in detail here.

[0102] In this embodiment, the transmission components are connected to the transmission seat 6 and the dough hook 5 respectively, and are used to drive the transmission seat 6 and the dough hook 5 to rotate. Specifically, the transmission components include a transmission shaft 10 and a first transmission component 7, a second transmission component 8, and a third transmission component 9 connected to the transmission shaft.

[0103] In this embodiment, the second transmission assembly 8 includes a first pulley assembly 801, a second pulley assembly 802, and a belt 803. The first pulley assembly 801 is disposed at the bottom end of the transmission shaft 10, the second pulley assembly 802 is connected to the transmission base 6, and the belt 803 connects the first pulley assembly 801 and the second pulley assembly 802. A bearing 804 is sleeved on one end of the transmission base 6 connected to the second pulley assembly 802. A support member 110 is fixedly disposed on the base 1, and a groove is provided on the support member 110, in which the bearing 804 is disposed. One end of the support member 110 extends into the lower body assembly 201 and is fixedly disposed on the lower body assembly 201. The power assembly 100 is disposed on the support member 110.

[0104] In this embodiment, in order to achieve shock absorption and extend the service life of the parts, a shock-absorbing silicone part 805 is provided between the bearing 804 and the transmission seat 6, and a bearing washer 808 is provided between the bearing 804 and the second pulley assembly 802.

[0105] In this embodiment, the second pulley assembly 802 includes a pulley bracket 806 and a pulley 807. The pulley 807 is fixedly mounted on the pulley bracket 806. One end of the transmission seat 6 is fixedly connected to the pulley bracket 806. The bearing washer 808 is disposed between the bearing 804 and the pulley bracket 806.

[0106] In order to further reduce friction between parts, eliminate noise, and extend the service life of parts, a wear-resistant pressure plate 809 is provided between the transmission seat 6 and the support 110.

[0107] In this embodiment, the drive shaft 10 includes a first universal joint drive shaft 101 and a second universal joint drive shaft 102. One end of the first universal joint drive shaft 101 is slidably connected to one end of the second universal joint drive shaft 102. The other end of the first universal joint drive shaft 101 is connected to the second transmission assembly 8, and the other end of the second universal joint drive shaft 102 is connected to the third transmission assembly 9.

[0108] In this embodiment, the power assembly 100 is connected to the transmission assembly and is used to drive the transmission assembly to move. Specifically, the power assembly 100 includes a geared motor, which is disposed within the lower body assembly 201 and fixedly mounted on the support member 110. The starting and speed of the geared motor can be controlled by control buttons and knobs disposed on the upper body assembly 202.

[0109] In this embodiment, the axis of the geared motor, the axis of the drive shaft 10, and the rotation axis of the dough hook 5 are parallel. Specifically, the axis of the drive shaft 10 is on one side of the plane formed by the axis of the geared motor and the rotation axis of the dough hook 5, and the distance between the projection of the axis of the drive shaft 10 on the horizontal plane and the plane formed by the axis of the geared motor and the rotation axis of the dough hook 5 is greater than 40mm and less than 55mm.

[0110] In this embodiment, the dough hook 5 is rotatably mounted on the head of the upper body assembly 202 along its own axis, and the dough hook 5 is detachably mounted on the upper body assembly 202. Specifically, the dough hook 5 includes a connecting shaft 501, a connecting part 502, and a working spiral part 503. The connecting shaft 501 is detachably connected to the upper body assembly 202 and connected to the third transmission assembly 9. The connecting part 502 connects the connecting shaft 501 and the working spiral part 503. The working spiral part 503 extends into the dough bowl 3 for stirring.

[0111] In this embodiment, the connecting part 502 is cylindrical, and the diameter of the working spiral part 503 gradually decreases as it moves away from the connecting part 502.

[0112] In this embodiment, the connecting shaft 501 is provided with a second limiting shaft 504 for preventing the dough hook 5 from rotating under force. The specific number of the second limiting shafts 504 is two, and they are arranged symmetrically opposite each other.

[0113] In this embodiment, a dough hook mounting member 206 is provided on the upper body assembly 202. The dough hook mounting member 206 has a slot 207 and a sliding groove 208.

The sliding groove 208 is circumferentially positioned on the inner wall of the dough hook mounting member 206 and connected to the slot 207, allowing the dough hook 5 to slide circumferentially along the dough hook mounting member 206. The number of slots 207 and sliding grooves 208 is the same as the specific number of the second limiting shaft 504.

[0114] When installing the dough hook 5, insert the connecting shaft 501 of the dough hook 5 into the dough hook mounting piece 206, and insert the second limiting shaft 504 from the slot 207. Rotate the dough hook 5, and the second limiting shaft 504 moves from the slot 207 to the slide groove 208 and slides within the slide groove 208 until it is installed and fixed in place. When disassembling the dough hook 5, the disassembly action is the reverse of the installation action.

[0115] In this embodiment, the dough-stopping rod 4 is detachably mounted on the head of the upper body assembly 202. Specifically, the dough-stopping rod 4 includes an assembly part 401, a working branch 402, and a fixing flange 404. The assembly part 401 is detachably fixed to the upper body assembly 202, the working branch 402 extends into the mixing bowl 3, and the fixing flange 404 is disposed between the assembly part 401 and the working branch 402.

[0116] In this embodiment, the cross-sectional area of ​​the assembly part 401 gradually decreases along the direction away from the working branch 402. The upper body assembly 202 is provided with a locking part 203, which has a hole adapted to the assembly part 401, and the assembly part 401 is inserted into the hole of the locking part 203. The dough stop bar here utilizes a tapered alignment design to connect with the upper body assembly 202, which can effectively prevent the dough stop bar 4 from swaying and improve the service life of the dough mixer.

[0117] In this embodiment, the assembly part 401 is shaped like a frustum, and the working branch 402 has a transverse cross section that is the same along its length. The transverse cross section is waist-shaped, circular, rectangular, or square; in this embodiment, it is specifically waist-shaped. This shape allows the dough to be cut better when the dough hook 5 intersects with the dough stop bar 4, while the cut has good strength and the dough can be easily pulled off the dough hook 5.

[0118] In this embodiment, the axis of the dough-blocking rod 4 is located on the central symmetry plane of the dough mixer and is parallel to the axis of the dough-kneading hook 5. The axis of the dough-blocking rod 4 and the axis of the dough-kneading hook 5 are not concentric. Specifically, the distance between the axes of the dough-blocking rod 4 and the dough-kneading hook 5 is 55-60mm. The positioning of the dough-blocking rod 4 and the dough-kneading hook 5 ensures that the dough mixer is subjected to even force during use. If the distance between them is too far, the dough-blocking rod 4 will be at the edge of the dough and will not play its role in blocking the dough. If the distance between the dough-blocking rod 4 and the axis of the dough-kneading hook 5 is too close, the dough-blocking rod 4 will bear a large resistance force, reducing its service life.

[0119] In this embodiment, the assembly part 401 is provided with a first limiting shaft 403 to prevent the stop bar 4 from rotating under force. Specifically, there is one first limiting shaft 403, which makes the stop bar 4 more stable during use.

[0120] In this embodiment, to further stabilize the stop rod 4, a locking assembly for locking the relative position of the stop rod 4 and the locking part 203 is provided. The locking assembly includes a thread on the fixed flange 404 and a locking nut 204 on the end of the locking part 203. The locking nut 204 engages with the thread on the fixed flange 404 to lock the relative position of the stop rod 4 and the locking part 203. The locking nut 204 presses the mating surfaces of the stop rod 4 and the locking part 203 together by locking with the thread. When the machine is in operation, the mating surfaces of the stop rod 4 and the locking part 203 are prevented from swaying due to the locking of the thread between the locking nut 204 and the fixed flange 404.

[0121] In this embodiment, a silicone pad 205 is provided between the locking part 203 and the locking nut 204, that is, the locking nut 204 and the locking part 203 are separated by a silicone pad 205. The function of this silicone pad 205 is to prevent the locking nut 204 from loosening.

[0122] In this embodiment, the dough mixer ensures excellent mixing of the dough as the dough hook 5 rotates, with the working spiral 503 rotating around the axis of the dough hook 5 gradually forming the dough. With each rotation of the dough hook 5, the working spiral 503 pushes the dough closer to the stop bar 4. The dough hook 5 and the stop bar 4 shear and stretch the dough, causing it to detach from the dough hook 5 and fall to the bottom of the mixing bowl 3 for re-mixing.

[0123] When the upper body assembly (202) and the lower body assembly (201) are in the first working state, the working spiral part (503) is adjacent to the bottom of the dough bowl (3) and is spaced about 2-5 mm away from the bottom.

[0124] In this embodiment, the dough hook 5 rotates in the same direction as the dough bowl 3, and there is a speed difference between the dough hook 5 and the dough bowl 3. In a specific embodiment, the ratio of the speed of the dough hook 5 to the speed of the dough bowl 3 is defined as a first transmission ratio, which is greater than or equal to 7 and less than or equal to 12. Preferably, the speed of the dough hook 5 is between 7 and 8 times the speed of the dough bowl 3, and the ratio of the speed of the dough bowl 3 to the speed of the dough hook 5 is greater than 13%. Specifically, the speed of the dough hook 5 is between 60 and 345 rpm, and the speed of the dough bowl 3 is between 8 and 50 rpm.

[0125] In this embodiment, the dough mixer makes both the dough hook 5 and the dough bowl 3 rotate, creating a speed difference, resulting in good dough-forming and kneading effects.

[0126] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
