Description

Technical Field

[0001] This application relates to the technical field of small household appliances, and particularly to a cooking machine. Background Art

[0002] A cooking machine includes a knife assembly, a motor, and a mixing cup. The knife assembly includes a knife shaft and a blade. The motor shaft is connected to the knife shaft through a connection structure (such as a clutch or a thread), etc. When the motor rotates, it can drive the blade of the knife assembly to rotate in the mixing cup.

[0003] In the above cooking machine, a connection is required between the knife shaft and the motor shaft, which easily causes the knife shaft and the motor shaft to be non-concentric. Non-concentricity will cause resonance or abnormal noise, resulting in poor user experience. Summary of the Utility Model

[0004] The purpose of this application is to disclose a cooking machine, which improves the concentricity between the knife shaft and the motor shaft, has no resonance and abnormal noise, and enhances the user experience.

[0005] This application discloses a cooking machine. The cooking machine includes a mixing cup, a motor, and a knife assembly. The motor includes a motor shaft. One section of the motor shaft serves as the knife shaft, and the knife shaft extends into the mixing cup. The knife assembly is detachably connected to the knife shaft, and the knife assembly is driven by the motor to rotate in the mixing cup.

[0006] With the above settings, one section of the motor shaft serves as the knife shaft, the knife shaft of the knife assembly is cancelled, and one section of the motor shaft serves as the knife shaft, avoiding the error caused by the assembly relationship between the knife shaft and the motor shaft in the related art (such as the error in machining the screw teeth and the error in assembly when the knife shaft and the motor shaft are engaged through screw teeth), resulting in non-concentricity between the knife shaft and the motor shaft. Therefore, one section of the motor shaft serving as the knife shaft can achieve better coaxiality, and there is no resonance between the mixing cup assembly and the base (or the main body), the noise is lower, and the user experience is improved. In addition, the knife assembly is detachably connected to the knife shaft, which is convenient for the knife assembly to be detached from the knife shaft for cleaning. After the knife assembly is detached, it is also convenient to clean the mixing cup without the knife assembly in the mixing cup.

[0007] In some embodiments, the knife shaft includes a plurality of driving edges extending in the up and down directions, and the deflection direction of the plurality of driving edges from bottom to top is opposite to the rotation direction of the knife assembly; the knife assembly includes a driving hole extending vertically in the up and down directions, and the driving hole includes a convex angle; the knife shaft is inserted into the driving hole, and the convex angle cooperates with the driving edge to achieve the detachable connection.

[0008] With the above settings, since the tool shaft is inserted into the driving hole, the tool assembly can be disassembled for cleaning, which is more convenient. After cleaning, the tool assembly can be inserted directly, and the assembly between the tool assembly and the tool shaft is also convenient. In addition, the tool shaft includes a deflected driving edge and the tool assembly includes a vertically extending driving hole, and the deflection direction of the driving edge is opposite to the rotation direction of the tool assembly. In this way, through the cooperation between the driving edge and the convex angle, during the rotation of the tool assembly, the deflected driving edge will apply a force to the convex angle of the tool assembly, making it difficult for the tool assembly to fall off the tool shaft.

[0009] In some embodiments, the number of the driving edges is equal to the number of the convex angles, and the number is 3 to 6.

[0010] With the above settings, since the number is 3 to 6, the driving edges of the tool shaft can cooperate more closely with the convex angles of the tool assembly, and it is not easy for the tool assembly to fall off. Because the larger the number, the closer the tool shaft and the driving hole are to a circular shape, the weaker the force of the driving edge on the convex angle, and it is easy for the tool assembly to slip between the tool shaft and the driving hole, resulting in the tool assembly being easy to fall off. Moreover, the larger the number, the more difficult it is to machine the tool shaft and the driving hole.

[0011] In some embodiments, the driving edge is deflected in a spiral shape, and the spiral angle is a, where 60° ≤ a < 90°.

[0012] With the above settings, the spiral angle satisfies 60° ≤ a < 90°, and the driving edge can apply a force to the convex angle during rotation to prevent the tool assembly from falling off.

[0013] In some embodiments, the tool assembly includes a tool sleeve, and the tool sleeve includes the driving hole and a receiving hole communicating with the driving hole; the receiving hole is larger than the driving hole and is coaxial with the driving hole; the tool shaft is inserted into the driving hole and penetrates into the receiving hole.

[0014] With the above settings, since the receiving hole is larger than the driving hole and is coaxial with the driving hole, it is convenient for the tool shaft to be inserted into the driving hole and penetrate into the receiving hole.

[0015] In some embodiments, the tool assembly includes a clamping member; after the tool shaft penetrates into the receiving hole, it is also in interference fit with the clamping member.

[0016] With the above settings, since the tool shaft is clamped with the clamping member, and the tool assembly includes the clamping member, during the process of pouring out the food in the mixing cup, because the tool shaft is clamped with the clamping member, the tool assembly will not fall off the tool shaft.

[0017] In some embodiments, the cooking machine includes a mixing cup assembly, a base, and a shock pad. The base includes an installation cavity. The mixing cup assembly includes the mixing cup, the motor, and the cutter assembly. The mixing cup assembly is located within the installation cavity, and the shock pad separates the bottom of the mixing cup assembly from the bottom of the installation cavity.

[0018] With the above arrangement, since the bottom of the mixing cup assembly is separated from the bottom of the installation cavity by the shock pad, in this way, the connection between the mixing cup assembly and the base is a soft connection. When the mixing cup assembly is working, part of the vibration generated is eliminated by the shock pad on the base, reducing the resonance between the mixing cup assembly and the base, reducing the noise and abnormal noise of the whole machine, and enhancing the user experience.

[0019] In some embodiments, an installation groove extending around the circumference of the installation cavity is provided at the bottom of the installation cavity. The shock pad is annular and is located within the installation groove. Alternatively, the bottom of the installation cavity is evenly distributed with installation grooves along the circumference. There are multiple shock pads, each corresponding to and located within one of the installation grooves.

[0020] With the above arrangement, regardless of whether the installation groove is annular, since the shock pad is located within the installation groove, the shock pad is not easily loosened and can better play a shock-absorbing role. When both the shock pad and the installation groove are annular, the shock pad is even less likely to fall off from the installation groove.

[0021] In some embodiments, jacks are provided at the bottom of the installation groove. The shock pad includes a shock pad body and insertion posts protruding from the shock pad body. The shock pad body is located within the installation groove and abuts against the bottom of the mixing cup assembly, and the insertion posts are inserted into the jacks.

[0022] With the above arrangement, through the insertion of the insertion posts into the jacks, the shock pad is not easily dropped from the installation groove.

[0023] In some embodiments, when the shock pad is annular, the shock pad is provided with multiple sections of grooves with the insertion posts as the demarcation points, and each section of the groove extends along the circumference of the shock pad.

[0024] With the above arrangement, by providing the grooves, during the process of installing the shock pad into the installation groove, because the shock pad is squeezed, the grooves are reduced. After the shock pad is completely installed into the installation groove, the shock pad needs to return to its original state, causing the side walls of the grooves to abut against the side walls of the installation groove. Thus, the shock pad is not easily detached and is also convenient to be installed into the installation groove. Description of the Drawings

[0041] Here, in combination with the accompanying drawings, the technical solutions in the embodiments (or "implementation modes") of this application will be clearly and completely described. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0042] If there are terms related to directional indication or positional relationship in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, lateral, length, width, counterclockwise, clockwise, axial direction, radial direction, circumferential direction, etc.), such terms are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0043] See Figure 2 and in combination with Figure 1 、 Figures 4 to 9 ,the present application discloses a cooking machine. The cooking machine includes a mixing cup 1, a motor 2, and a knife assembly 3. The motor 2 can be a series-wound motor as shown in Figure 2 and Figures 4 to 6 , or a brushless motor as shown in Figure 7 and Figure 8 . Regardless of the type of motor 2, the motor 2 includes a motor shaft 21. One section of the motor shaft 21 serves as a knife shaft 211. For example, it can be understood that the knife shaft 211 of the knife assembly is integrally formed with the motor shaft of the motor 2 itself, or in other words, the motor shaft described in the present application extends the motor shaft of the motor 2 itself, and the extended part serves as the knife shaft 211. The knife shaft 211 extends into the mixing cup 1. The knife assembly 3 is detachably connected to the knife shaft 211. The knife assembly 3 is driven by the motor 2 to rotate in the mixing cup 1.

[0044] With the above settings, one section of the motor shaft 21 serves as the knife shaft 211, the knife assembly 3 eliminates the knife shaft 211, and one section of the motor shaft 21 serves as the knife shaft 211, avoiding the error caused by the assembly relationship between the knife shaft 211 and the motor shaft 21 in the related art (such as the error in machining the screw thread and the error in assembly when the knife shaft and the motor shaft are in screw thread fit), resulting in the non-concentricity of the knife shaft 211 and the motor shaft 21. Therefore, since one section of the motor shaft 21 serves as the knife shaft 211, the coaxiality can be better, the mixing cup assembly and the base (or the main body) have no resonance, the noise is lower, and the user experience is improved. In addition, the knife assembly 3 is detachably connected to the knife shaft 211, which also facilitates the removal of the knife assembly 3 from the knife shaft 211 for cleaning. After the knife assembly 3 is removed, the absence of the knife assembly 3 in the mixing cup 1 also facilitates the cleaning of the mixing cup 1.

[0045] The implementation manner of how the knife shaft 211 is detachably connected to the knife assembly 3 is not limited. As follows, an implementation manner of realizing the detachable connection between the knife shaft 211 and the knife assembly 3 is described as follows:

[0046] See Figure 6and Figure 8 The tool shaft 211 includes a plurality of driving edges 2111 extending in the up and down directions. The deflection direction of the plurality of driving edges 2111 from bottom to top is opposite to the rotation direction of the tool assembly 3. As Figure 6 and Figure 8 shown, after the driving edge 2111 deflects, the side surface of the tool shaft 211 is a spiral surface 2112. The tool assembly 3 includes a driving hole 311 extending vertically in the up and down directions, and the driving hole 311 includes a convex angle 3111. The tool shaft 211 is inserted into the driving hole 311, and the convex angle 3111 cooperates with the driving edge 2111. Although Figure 6 and Figure 8 show four driving edges 2111 and four convex angles 3111, however, based on the function of the cooperation between the driving edge 2111 and the convex angle 3111, the number of driving edges 2111 is not limited to four sides and the number of convex angles 3111 is not limited to four.

[0047] With the above arrangement, since the tool shaft 211 is inserted into the driving hole 311, the tool assembly 3 can be disassembled for cleaning, and the cleaning of the tool assembly 3 is more convenient. After cleaning, the tool assembly 3 can be inserted, and the assembly between the tool assembly 3 and the tool shaft 211 is also convenient. In addition, the tool shaft 211 includes a deflected driving edge 2111 and the tool assembly 3 includes a driving hole 311 extending vertically, and the deflection direction of the driving edge 2111 is opposite to the rotation direction of the tool assembly 3. In this way, through the cooperation between the driving edge 2111 and the convex angle 3111, during the rotation of the tool assembly 3, the deflected driving edge 2111 will exert a force on the convex angle 3111 of the tool assembly 3, so that the tool assembly 3 is not easily detached from the tool shaft 211.

[0048] In some embodiments, the number of the driving edges 2111 is equal to the number of the convex angles 3111, and the number is 3 to 6. For example, the number of the driving edges 2111 and the number of the convex angles 3111 are both 3, both 4, both 4 or both 6.

[0049] With the above arrangement, since the number is 3 to 6, the driving edges 2111 of the tool shaft 211 can cooperate more closely with the convex angles 3111 of the tool assembly 3, and the tool assembly 3 is not easily detached. Because the more the number, the closer the tool shaft 211 and the driving hole 311 are to a circular shape, the weaker the force of the driving edge 2111 on the convex angle 3111, and it is easy to slip between the tool assembly 3 and the tool shaft 211, resulting in the tool assembly 3 being easily detached. Moreover, the larger the number, the more difficult it is to machine the tool shaft 211 and the driving hole 311.

[0050] In some embodiments, the driving edge 2111 deflects into a spiral shape, and the spiral angle is a, 60 degrees ≤ a < 90 degrees.

[0051] With the above settings, the spiral angle satisfies 60° ≤ α < 90°, and during rotation, the driving edge 2111 can exert a force on the convex corner 3111 to prevent the knife assembly 3 from falling off.

[0052] See Figure 10 and in combination with Figure 9 and Figure 11 , the knife assembly 3 includes a knife sleeve 31. The knife sleeve 31 includes the driving hole 311 and a receiving hole 312 communicating with the driving hole 311. The receiving hole 312 is larger than the driving hole 311 and is coaxial with the driving hole 311. In this way, as Figure 9 and Figure 10 shown, a step 3120 is formed at the bottom of the receiving hole 312. See Figure 9 , the knife shaft 211 is inserted into the driving hole 311 and penetrates into the receiving hole 312. In an embodiment of the present application, the knife shaft 211 has a clearance fit with the driving hole 311, and the clearance is c, where 0.1 mm ≤ c ≤ 1.0 mm. The depth h of the driving hole 311 is determined according to the situation. It can be understood that after forming the step, the side wall of the driving hole 311 is equivalent to a convex block. In this case, the depth h of the driving hole 311 satisfies 1 mm ≤ h ≤ 5 mm.

[0053] With the above settings, since the receiving hole 312 is larger than the driving hole 311 and is coaxial with the driving hole 311, it is convenient for the knife shaft 211 to be inserted into the driving hole 311 and penetrate into the receiving hole 312.

[0054] In an embodiment of the present application, the knife assembly 3 further includes a blade 32, a knife handle 33, a gasket 34, and a knife cover 35. The knife handle 33 and the knife sleeve 31 are threadedly connected to clamp the blade 32. The gasket 34 is located between the blade 32 and the knife sleeve 31. The knife cover 35 covers the knife handle 33.

[0055] See Figures 9 to 11 , the knife assembly 3 includes a clamping member 36; after the knife shaft 211 penetrates into the receiving hole 312, it has an interference fit with the clamping member 36. The interference amount can be determined according to the actual situation. In an embodiment of the present application, the interference amount is d, where 0.1 mm ≤ d ≤ 1.5 mm.

[0056] With the above settings, since the knife shaft 211 is clamped with the clamping member 36, and the knife assembly 3 includes the clamping member 36, during the process of pouring out the food in the mixing cup 1, because the knife shaft 211 is clamped with the clamping member 36, the knife assembly 3 will not fall off the knife shaft 211.

[0057] See Figures 1 to 4 as well as Figure 12 and Figure 13, the cooking machine includes a mixing cup assembly 10, a base 20, and a shock pad 30. In some embodiments, the cooking machine further includes a sound insulation cover 40. The base 20 includes an installation cavity 201. The mixing cup assembly 10 includes the mixing cup 1, the motor 2, and the knife assembly 3. In other embodiments, it may also be that the base includes the motor. For example, the mixing cup assembly and the base are non-detachable. Refer to Figure 2 and Figure 3 and combine with Figure 4 and Figure 1 , the mixing cup assembly 10 is located in the installation cavity 201, and the bottom 101 of the mixing cup assembly 10 is separated from the bottom of the installation cavity 201 by the shock pad 30. Based on the function of the shock pad 30, the structure of the shock pad 30 is not limited.

[0058] With the above settings, since the bottom 101 of the mixing cup assembly 10 is separated from the bottom of the installation cavity 201 by the shock pad 30, in this way, the mixing cup assembly 10 and the base 20 are in soft connection. Part of the vibration generated when the mixing cup assembly 10 works is eliminated by the shock pad 30 on the base 20, reducing the resonance between the mixing cup assembly 10 and the base 20, reducing the noise and abnormal noise of the whole machine, and improving the user experience.

[0059] Refer to Figures 12 to 16 , a mounting groove 2011 is provided at the bottom of the installation cavity 201 around the circumference of the installation cavity. The shock pad 30 is annular and is located in the mounting groove 2011. As a variation of the above embodiment, the bottom of the installation cavity 201 is evenly distributed with mounting grooves 2011 along the circumference. There are multiple shock pads, which are respectively located in the mounting grooves 2011.

[0060] With the above settings, regardless of whether the mounting groove 2011 is annular, by the shock pad 30 being located in the mounting groove 2011, the shock pad 30 is not easy to loosen and can better play a shock-absorbing role. When both the shock pad 30 and the mounting groove 2011 are annular, the shock pad 30 is more difficult to fall off from the mounting groove 2011.

[0061] Refer to Figure 16 , a jack 20111 is provided at the bottom of the mounting groove 2011. The jacks 20111 can be evenly distributed or unevenly distributed in the circumference of the installation cavity 201. Refer to Figure 15 , the shock pad 30 includes a shock pad body 301 and a plug post 302 protruding from the shock pad body 301. Refer to Figure 13 and Figure 3 , the shock pad body 301 is located in the mounting groove 2011 and abuts against the bottom 101 of the mixing cup assembly. The plug post 302 is inserted into the jack 20111.

[0062] With the above settings, by inserting the insertion post 302 into the insertion hole 20111, the shock pad 30 is not easily detached from the installation groove 2011.

[0063] See Figure 15 and in combination with Figure 14 , when the shock pad 30 is in a ring shape, with the insertion post 302 as the demarcation point, the shock pad 30 is provided with multiple sections of grooves 303, and each section of the groove 303 extends along the circumferential direction of the shock pad 30. As Figure 15 shown, the shock pad 30 has three insertion posts 302, and there is one section of groove 303 between every two adjacent insertion posts 302, with a total of three sections of grooves 303, and each section of the groove 303 is arc-shaped. In some embodiments, there may also be two or more sections of grooves 303 between every two adjacent insertion posts 302.

[0064] With the above settings, by providing the groove 303, during the process of installing the shock pad 30 into the installation groove 2011, since the shock pad 30 is squeezed, the groove 303 is reduced. After the shock pad 30 is completely installed in the installation groove 2011, the shock pad 30 needs to return to its original state, and the side wall of the groove 303 abuts against the side wall of the installation groove 2011. Thus, the shock pad 30 is not easily detached and is also convenient to be installed into the installation groove 2011.

[0065] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the scope of protection of this application.
