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 main body, a mixing cup, a cutter head, a seal, and a blade. The cutter head and the mixing cup enclose a food processing cavity. The blade is assembled with the cutter head and is located above the front of the cutter head. The main body drives the blade to rotate in the food processing cavity, thereby processing food, such as making soy milk, squeezing fruit juice, and so on.
[0003] The seal is used to seal the back of the cutter head and the motor shaft. However, during use, there is a risk of eccentricity of the seal, resulting in eccentric wear, which is not conducive to effective sealing. Summary of the Utility Model
[0004] The purpose of this application is to disclose a cooking machine. The cooking machine can reduce the risk of eccentric wear of the seal and ensure effective sealing.
[0005] In a first aspect, this application discloses a cooking machine. The cooking machine includes a cutter head, a mounting member, a seal, a motor shaft, a blade, and a gasket. The cutter head includes a front of the cutter head and a back of the cutter head. The motor shaft passes through the mounting member, the seal, and the cutter head; the blade is assembled on the motor shaft and is located above the front of the cutter head. The seal seals the back of the cutter head and the motor shaft and includes a seal body through which the motor shaft passes. The gasket is assembled on the mounting member and includes a gasket body through which the motor shaft passes; a limiting mechanism is provided between the gasket body and the seal body; the limiting mechanism restricts the movement of the gasket and the seal in the radial direction of the motor shaft.
[0006] With the above arrangement, the movement of the gasket and the seal in the radial direction of the motor shaft is restricted by the limiting mechanism, ensuring a high concentricity between the seal and the motor shaft, reducing the risk of eccentric wear of the seal, and ensuring effective sealing of the seal. For example, the risk of water leakage between the seal and the motor shaft is reduced to ensure effective sealing of the seal to the motor shaft. In some cases, it can also ensure effective sealing of the seal to the back of the cutter head.
[0007] In some embodiments, the seal includes a seal flange around the seal body; the seal is located between the mounting member and the cutter head, and when the seal flange (32) abuts against the back of the cutter head, it turns outward to seal the back of the cutter head.
[0008] With the above settings, since the flange of the seal wraps around the seal body for one week, and when the flange of the seal abuts against the back of the cutter head, it turns outwards to seal the back of the cutter head. In this way, the flange of the seal can fit against the back of the blade. Moreover, the tighter the cutter head abuts against the seal, the larger the fitting area. Eventually, the seal can effectively seal the back of the cutter head and prevent water leakage.
[0009] In some embodiments, a sealing rib protrudes from the top surface of the seal body; the sealing rib wraps around the motor shaft for one week and is located within the cavity formed by the flange of the seal; the sealing rib seals the back of the cutter head.
[0010] With the above settings, both the sealing rib and the flange of the seal can seal the back of the cutter head. In this way, the seal can more effectively seal the back of the cutter head and better prevent water leakage.
[0011] In some embodiments, a reinforcing member is provided within the seal, and the reinforcing member wraps around the seal for one week; the flange of the seal is located diagonally above the reinforcing member.
[0012] With the above settings, since the flange of the seal is located diagonally above the reinforcing member, when the flange of the seal fits against the back of the cutter head, it will not be affected by the strength of the reinforcing member, and it is more capable of achieving a larger fitting area between the flange of the seal and the back of the cutter head.
[0013] In some embodiments, the flange of the seal forms a flared shape.
[0014] With the above settings, since the flange of the seal forms a flared shape, it is more capable of achieving a larger fitting area between the flange of the seal and the back of the cutter head.
[0015] In some embodiments, the limiting mechanism includes a gasket limiting portion and a seal limiting portion. The gasket limiting portion protrudes from the gasket body; both the gasket limiting portion and the seal limiting portion wrap around the motor shaft for one week and are concentric circles; the gasket limiting portion and the seal limiting portion are sleeved with each other. Alternatively, the limiting mechanism includes a plurality of gasket limiting portions and a plurality of seal limiting portions; the plurality of gasket limiting portions protrude from the gasket body and are evenly distributed circumferentially around the motor shaft; the plurality of seal limiting portions are evenly distributed circumferentially around the motor shaft; the gasket limiting portions and the seal limiting portions are in radial abutment with each other one by one. Alternatively, the limiting mechanism includes a sleeved gasket limiting portion and a seal limiting portion, and the gasket limiting portion protrudes from the gasket body; one of the gasket limiting portion and the seal limiting portion forms a circle around the motor shaft, and the other is arranged at intervals in the circumferential direction of the motor shaft, and the gasket limiting portion and the seal limiting portion are in abutment with each other.
[0016] With the above settings, by setting the spacer limiting part and the seal limiting part, it can better ensure a high concentricity between the seal and the motor shaft, reduce the risk of eccentric wear of the seal, and reduce the risk of water leakage between the seal and the motor shaft.
[0017] In some embodiments, the seal body includes a plurality of sealing lips spaced along the axial direction of the motor shaft, and each sealing lip converges in the direction from the mounting member to the blade to form a sealing lip opening; the motor shaft passes through the sealing lip opening of each sealing lip to achieve multiple seals for the motor shaft.
[0018] With the above settings, through the respective sealing lip openings of the plurality of sealing lips, multiple seals are achieved for the motor shaft. In this way, the seal can effectively seal the motor shaft.
[0019] In some embodiments, the seal is an oil seal.
[0020] In some embodiments, the cooking machine includes an elastic member. The mounting member includes a mounting groove, and the seal body is located in the mounting groove. The elastic member is located on the bottom wall of the mounting groove, and the opposite sides of the spacer are respectively in contact with the elastic member and the seal body. The seal body is in clearance fit with the groove wall of the mounting groove.
[0021] With the above settings, by providing the mounting groove, the spacer and the elastic member are located in the mounting groove, and the seal body is in clearance fit with the groove wall of the mounting groove. In this way, it is convenient to install the spacer, the elastic member and the seal.
[0022] In some embodiments, the elastic member includes an abutting portion, and the heights of the abutting portions relative to the bottom wall of the mounting groove are equal.
[0023] With the above settings, since the heights of the abutting portions relative to the bottom wall of the mounting groove are equal, the seal will not tilt. In this way, the flanging of the seal better fits the back of the cutter head and seals more effectively. In addition, the above settings can also ensure that under the elastic force provided by the elastic member, the seal will not skew. Furthermore, the concentricity between the seal and the motor shaft is high, reducing the risk of eccentric wear of the seal and the risk of water leakage between the seal and the motor shaft.
[0024] In some embodiments, the contact between the abutting portion and the spacer forms a ring around the motor shaft.
[0025] With the above settings, the contact area between the abutting part and the gasket forms a ring around the motor shaft for one week, sealing the back of the sealing cutter head in a circular shape, so that the flange of the seal can better fit the back of the cutter head, with good sealing effect. In addition, considering that the height of the aforementioned abutting part is equal to that of the bottom wall of the installation groove, the pressing force on the back of the cutter head is equal. Furthermore, the flange of the seal can more effectively seal the back of the cutter head.
[0026] In some embodiments, the elastic member is an O-ring, and the center of the elastic member is located on the rotation center line of the motor shaft.
[0027] With the above settings, the elastic member is an O-ring, which can better ensure a high concentricity between the seal and the motor shaft, reduce the risk of eccentric wear of the seal, and reduce the risk of water leakage between the seal and the motor shaft. In addition, because the O-ring is annular, it will not break (for example, it is not easy to break compared with a corrugated gasket), ensuring that the height of the abutting part relative to the bottom wall of the installation groove is equal. Thus, the flange of the seal can better fit the back of the cutter head and provide more effective sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Here, the technical solutions in the embodiments (or "embodiment modes") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0034] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial direction, radial direction, circumferential direction, etc.), such terms are only used to explain the relative positional relationships, 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, terms such as "first" and "second" involved in the embodiments of the present application are only for the purpose of convenient description and cannot be construed as indicating or implying relative importance.
[0035] See Figure 1 、 Figure 3 and Figure 4 , the present application discloses a cooking machine. The cooking machine includes a cutter head 1, a mounting member 2, a seal 3, a motor shaft 4, a blade 5 and a gasket 6. The cutter head 1 includes a heating plate 11 and a heating plate mounting member 12 in the embodiment of the present application. The structure of the cutter head 1 is not limited thereto. The cutter head 1 includes a cutter head front surface and a cutter head back surface.
[0036] The motor shaft 4 passes through the mounting member 2, the seal 3 and the cutter head 1. The blade 5 is assembled on the motor shaft 4 and is located above the cutter head front surface. One function of the mounting member 2 is to mount the seal 3, and the structure is not limited to that shown in the figure.
[0037] Combined with Figure 4 and Figure 5 , the seal 3 seals the back surface of the blade and the motor shaft 4. The seal 3 includes a seal body 31 through which the motor shaft 4 passes.
[0038] The gasket 6 is assembled on the mounting member 2. The gasket 6 includes a gasket body 61 through which the motor shaft 4 passes. As Figure 5 shown, a body through hole 611 of the gasket body 61 allows the motor shaft 4 to pass through. A limiting mechanism 60 is provided between the gasket body 61 and the seal body 31. The limiting mechanism 60 restricts the movement of the gasket 6 and the seal 3 in the radial direction of the motor shaft 4.
[0039] With the above settings, the radial movement between the gasket 6 and the seal 3 is restricted by the limiting mechanism 60, ensuring a high concentricity between the seal 3 and the motor shaft 4, reducing the risk of eccentric wear of the seal 3, and ensuring the effective sealing of the seal 3. For example, the risk of water leakage between the seal 3 and the motor shaft is reduced to ensure the effective sealing of the seal 3 to the motor shaft 4. Of course, since the seal 3 is not easily eccentrically worn, in some cases, it can also ensure the effective sealing of the seal 3 to the back of the cutter head (for example, the flanged edge 32 of the seal effectively seals the back of the cutter head as described later).
[0040] In the food processor shown in the present application, the food processor includes a mixing cup assembly 100 and a main body 200. The mixing cup assembly 100 includes a mixing cup 20, the aforementioned cutter head 1, a seal 3, a blade 5, and a gasket 6. In the present embodiment, the mixing cup assembly 100 further includes a handle assembly 30. The cutter head 1 is sealingly connected to the mixing cup 20 to enclose a food processing cavity 201. The blade 5 is located in the food processing cavity 201. The main body 200 includes a motor assembly 202. In the embodiment of the present application, the motor assembly 202 is hoisted on the mounting member 2. The motor shaft 4 of the motor assembly 202 extends into the mixing cup 20, and the food processor is a direct-drive food processor. The main body 200 drives the blade 5 to rotate in the food processing cavity 201. In addition, the main body 200 further includes a main body housing 203, an air outlet hood 204, a clutch 205, and a coupler seal ring 206. The main body housing 203, the air outlet hood 204, the clutch 205, and the coupler seal ring 206 can be assembled in any manner. The mounting member 2 is used to hoist the motor assembly 202 and can be understood as a motor bracket. In some embodiments, the mounting member 2 may not be a motor bracket either.
[0041] In some embodiments, the seal 3 includes a seal flanged edge 32 that surrounds the seal body 31 for one week. The structure of the seal flanged edge 32 is not limited as long as the subsequent functions can be achieved. In the embodiment of the present application, the cavity surrounded by the seal flanged edge 32 gradually increases in the direction away from the seal body 31. In Figure 5 , the direction of arrow F is outward. The cavity gradually increases in the direction of arrow f. Refer to Figure 4 , regardless of the structure of the seal flanged edge 32, in the present application, the seal 3 is located between the mounting member 2 and the cutter head 1. When the seal flanged edge 32 abuts against the back of the cutter head, it turns outward to seal the back of the cutter head.
[0042] With the above settings, since the seal flanged edge 32 surrounds the seal body 31 for one week, and when the seal flanged edge 32 abuts against the back of the cutter head, it turns outward to seal the back of the cutter head. In this way, refer to Figure 4, the flanging 32 of the seal can be in contact with the back of the blade. Moreover, the tighter the cutter head 1 is in contact with the seal 3, the larger the contact area. Eventually, the seal 3 can effectively seal the back of the cutter head and prevent water leakage from the top surface of the seal 3.
[0043] See Figure 5 and in combination with Figure 4 , a sealing rib 311 protrudes from the top surface of the seal body 31. The sealing rib 311 surrounds the motor shaft 4 for one week and is located in the cavity surrounded by the flanging 32 of the seal. The sealing rib 311 seals the back of the cutter head.
[0044] With the above settings, both the sealing rib 311 and the flanging 32 of the seal can seal the back of the cutter head. In this way, the seal 3 can more effectively seal the back of the cutter head and prevent water leakage more effectively.
[0045] See Figure 4 and Figure 5 , in some embodiments, a reinforcing member 9 is provided inside the seal 3. The reinforcing member 9 surrounds the seal 3 for one week; the flanging 32 of the seal is located diagonally above the reinforcing member 9.
[0046] With the above settings, since the flanging 32 of the seal is located diagonally above the reinforcing member 9, when the flanging 32 of the seal is in contact with the back of the cutter head, it will not be affected by the strength of the reinforcing member 9, and the contact area between the flanging 32 of the seal and the back of the cutter head can be larger.
[0047] See Figure 5 and Figure 4 , in some embodiments, the flanging 32 of the seal forms a trumpet shape.
[0048] With the above settings, since the flanging 32 of the seal forms a trumpet shape, the contact area between the flanging 32 of the seal and the back of the cutter head can be larger.
[0049] In some embodiments, the seal 3 is an oil seal. Of course, it is not limited to this, as long as the back of the cutter head can be sealed.
[0050] See Figure 5 , the limiting mechanism 60 includes a gasket limiting portion 601 and a seal limiting portion 602. The gasket limiting portion 601 and the seal limiting portion 602 both surround the motor shaft 4 for one week and are concentric circles; the gasket limiting portion 601 and the seal limiting portion 602 are sleeved with each other. Figure 4 It is shown that the gasket limiting portion 601 is located inside the seal limiting portion 602 and is sleeved by the seal limiting portion 602. In some other embodiments, it can also be that the gasket limiting portion 601 is located outside the seal limiting portion 602 and the seal limiting portion 602 is sleeved.
[0051] With the above settings, since both the gasket limiting part 601 and the seal limiting part 602 surround the motor shaft 4 for one week, and are concentric circles and nested with each other, in this way, it is ensured that the concentricity between the seal 3 and the motor shaft 4 is high, reducing the risk of eccentric wear of the seal 3 and ensuring the effective sealing of the seal 3. For example, reducing the risk of water leakage between the seal 3 and the motor shaft 4 to ensure the effective sealing of the seal 3 to the motor shaft 4. In some cases, it can also ensure the effective sealing of the seal 3 to the back of the cutter head.
[0052] The above gasket limiting part 601 can be considered to be composed of multiple continuous limiting parts, and the seal limiting part 602 can also be considered to be composed of multiple continuous limiting parts. As a variation of the above embodiment, both the seal limiting part and the gasket limiting part are discontinuous, that is, the limiting mechanism 60 includes multiple gasket limiting parts 601 and multiple seal limiting parts 602. The multiple gasket limiting parts 601 protrude from the gasket body and are evenly distributed around the circumference of the motor shaft 4. The multiple seal limiting parts 602 are evenly distributed around the circumference of the motor shaft 4. The gasket limiting part 601 and the seal limiting part 602 are in radial abutment with each other one by one on the motor shaft 4.
[0053] Or, as a variation of the above embodiment, it can also be that one of the gasket limiting part 601 and the seal limiting part 602 is circular, and the other is discontinuous, that is, the limiting mechanism includes a nested gasket limiting part and seal limiting part. The gasket limiting part protrudes from the gasket body. One of the gasket limiting part and the seal limiting part is circular around the motor shaft for one week, and the other is arranged at intervals around the motor shaft for one week, and the gasket limiting part and the seal limiting part are in abutment with each other.
[0054] With the above settings, through the mutual cooperation of the gasket limiting part and the seal limiting part for limiting, it can better prevent the seal 3 from tilting, ensure that the concentricity between the seal 3 and the motor shaft 4 is high, reduce the risk of eccentric wear of the seal 3 to ensure effective sealing, reduce the risk of water leakage between the seal 3 and the motor shaft 4 to ensure the effective sealing of the seal 3 to the motor shaft 4. In some cases, it can also ensure the effective sealing of the seal 3 to the back of the cutter head.
[0055] See Figure 5 and in combination with Figure 4 , the seal body 31 includes multiple seal lips 312. Figure 5 and Figure 4Three sealing lips 312 are shown in the figure, however, the number of the sealing lips 312 is not limited to this. Each sealing lip 312 converges along the direction from the mounting member 2 to the blade 5 to form a sealing lip opening 3121, that is, the sealing lips 312 enclose a hollow frustum shape, and decrease along the direction of arrow f to form the sealing lip opening 3121. The motor shaft 4 passes through the sealing lip opening 3121 of each sealing lip 312 to achieve multiple seals for the motor shaft 4.
[0056] With the above settings, through the respective sealing lip openings 3121 of the multiple sealing lips 312, multiple seals are achieved for the motor shaft 4. In this way, the seal 3 can effectively seal the motor shaft 4 and is less likely to leak water.
[0057] Refer to Figure 4 and combine with Figure 1 , the cooking machine includes a gasket 6 and an elastic member 7. The mounting member 2 includes a mounting groove 21. The elastic member 7 is located on the bottom wall of the mounting groove 21, and the opposite sides of the gasket 6 are respectively in contact with the elastic member 7 and the seal body 31. The seal body 31 is in clearance fit with the groove wall of the mounting groove 21.
[0058] With the above settings, by providing the mounting groove 21, the gasket 6 and the elastic member 7 are located in the mounting groove 21, and the seal body 31 is in clearance fit with the groove wall of the mounting groove 21. In this way, it is convenient to install the gasket 6, the elastic member 7 and the seal 3.
[0059] Refer to Figure 5 and Figure 4 , the elastic member 7 includes a abutting portion 71, and the heights of the abutting portion 71 relative to the bottom wall of the mounting groove 21 are equal.
[0060] With the above settings, since the heights of the abutting portion 71 relative to the bottom wall of the mounting groove 21 are equal, the seal 3 will not tilt. In this way, the flanging 32 of the seal fits better with the back of the cutter head and seals more effectively. In addition, the above settings can also make the seal 3 not skew under the elastic force provided by the elastic member 7. Furthermore, the concentricity between the seal 3 and the motor shaft 4 is high, reducing the risk of eccentric wear of the seal 3 and the risk of water leakage between the seal 3 and the motor shaft 4.
[0061] Refer to Figure 5 , in some embodiments, the contact portion between the abutting portion 71 and the gasket 6 forms a ring around the motor shaft 4. The ring is not limited to the O-ring (i.e., circular ring) shown in the figure.
[0062] With the above settings, the contact portion between the abutting portion 71 and the gasket 6 forms a ring around the motor shaft for one week, sealing the back of the sealing cutter head in a circle so that the flange 32 of the seal can better fit the back of the cutter head, with good sealing effect. In addition, considering that the height of the abutting portion 71 is equal to that of the bottom wall of the mounting groove, the pressing force on the back of the cutter head is equal. Furthermore, the flange 32 of the seal can seal the back of the cutter head more effectively.
[0063] Continue to refer to Figure 5 , in one embodiment, the elastic member 7 is an O-ring, and the center of the elastic member 7 is located on the rotation center line of the motor shaft 4. Of course, based on the function of the elastic member 7, in some embodiments, the elastic member 7 may not be an O-ring.
[0064] With the above settings, the elastic member 7 being an O-ring can better ensure a high concentricity between the seal 3 and the motor shaft 4, reducing the risk of eccentric wear of the seal 3 and the risk of water leakage between the seal 3 and the motor shaft 4. In addition, since the O-ring is in a ring shape, it will not break (for example, it is not as easy to break as a corrugated gasket), ensuring that the height of the abutting portion 71 relative to the bottom wall of the mounting groove is equal. Thus, the flange 32 of the seal can better fit the back of the cutter head and seal more effectively.
[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.
