Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with precise positioning. Background Art

[0002] Existing food processors usually include a body with a casing, a cup body arranged in the casing and having a grinding chamber, a grinding device arranged in the grinding chamber, and a motor transmission-connected to the grinding device. When a user uses the food processor, the food is placed in the grinding chamber of the cup body, and the motor rotates at high speed and drives the grinding device to rotate to realize the processing of the food. In order to meet the processing needs of different ingredients, the cup body is usually set to be detachable inside the machine body, and different cup bodies such as chopping cup, minced meat cup, dry grinding cup, etc. can be replaced to meet the user's usage needs. In this type of machine, in order to realize the transmission connection between the motor and the crushing device in the machine body, a lower coupling connected to the motor transmission is usually set on the machine body, and an upper coupling connected to the crushing device transmission is set on the cup body. After the cup body is installed in place, the upper and lower couplings are aligned and matched to achieve torque transmission. However, when the cup body of this type of machine is installed on the machine body, the positioning of the cup body is only achieved through the coupling of the upper and lower couplers and the alignment of components such as the water inlet pipe. This results in poor coaxiality between the upper and lower couplings, poor transmission stability of the two and will generate large friction noise. In particular, when the rotation speed of the crushing device is high, the knife shaft of the crushing device may deflect, resulting in interruption of food processing, which seriously affects the consumer's usage experience. Utility Model Content

[0003] The utility model aims to provide a food processing machine with accurate positioning, so as to solve the problem that the coaxiality of the upper and lower couplings is low, the transmission is unstable and noise is generated due to the inaccurate positioning of the detachable cup body when it is installed on the machine body in the existing food processing machine.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with precise positioning, comprising a machine body, a cup body arranged on the machine body and having a crushing chamber, a crushing device arranged in the crushing chamber and a motor connected to the crushing device in transmission, the machine body comprising an outer shell, the cup body being detachably arranged in the outer shell, a support frame for fixing the motor being provided under the cup body, an upper coupling connected to the crushing device in transmission at the bottom end of the cup body, a lower coupling matched to the upper coupling in transmission at the top end of the support frame, and mutually matching positioning structures being provided at the bottom end of the cup body and the top end of the support frame, a plurality of positioning structures being arranged at intervals along the circumference of the cup body and the support frame, and the center of a circle formed by the plurality of positioning structures being located on the axis of the upper coupling and the lower coupling.

[0005] The present application makes the cup body detachable and arranged in the shell, so that the user can replace different cup bodies according to different usage requirements, such as a crushing cup, a dry grinding cup and a minced meat cup, so as to process different ingredients, thereby improving the user experience. At the same time, the bottom of the cup body is provided with an upper coupling connected to the crushing device, and the top of the support frame is provided with a lower coupling matched with the upper coupling, so that after the user installs the cup body in the shell, the motor torque can be transmitted through the cooperation of the upper and lower couplings to ensure the normal operation of the crushing device. In addition, the bottom of the cup body and the top of the support frame are also provided with mutually cooperating positioning structures, and the positioning structures are arranged at intervals along the circumference of the cup body and the support frame, so that the cup body and the support frame can improve the cooperation effect of the two with the help of the positioning cooperation of the positioning structure, ensure the stability of the connection and cooperation between the two, and avoid the situation where the two collide with each other and generate noise due to unstable cooperation, and there are multiple positioning structures, which can ensure that the positioning structure can realize the positioning of the two in multiple directions in the circumference, further improving the positioning effect.

[0006] At the same time, the center of the circle formed by the multiple positioning structures is located on the axis of the upper coupling and the lower coupling, so that after the cup body is installed in place, with the help of the positioning structure, the cup body and the support frame can be radially centered and matched, so that the axis of the upper coupling and the axis of the lower coupling are colinear, thereby improving the coaxiality of the upper coupling and the lower coupling, ensuring the stability of the transmission when the torque is transmitted between the upper coupling and the lower coupling, especially when the crushing device rotates at high speed, avoiding the low coaxiality of the upper and lower couplings causing large vibration and noise during the transmission of the two, and even causing the crushing device to have a sway transmission failure, thereby ensuring the stability of the whole machine operation.

At the same time, the center of the circle formed by the inner side walls of the multiple positioning grooves is located on the axis of the upper coupling, and the center of the circle formed by the inner side walls of the multiple positioning protrusions is located on the axis of the lower coupling, so that after the cup body is installed in place, the center of the circle formed by the arc surface of the positioning groove and the positioning protrusion is also located on the axis of the upper coupling and the lower coupling, thereby ensuring the radial centering of the cup body and the support frame, so that the upper coupling and the lower coupling are located on the same axis, and further the coaxiality of the upper coupling and the lower coupling.

[0009] In a preferred implementation of a food processing machine with precise positioning, the cup body is provided with a drain port, a drain valve is provided at the drain port, the drain valve includes a valve core for controlling the opening and closing of the drain port and a slurry discharge nozzle connected to the valve core, the valve core is detachable with the cup body, and the slurry discharge nozzle is detachably arranged on a support frame, the axis of the valve core is located on a circle formed by the inner side wall of the positioning groove, and the axis of the slurry discharge nozzle is located on a circle formed by the inner side wall of the positioning protrusion.

[0010] By setting the valve core to be detachable with the cup body, and the slurry discharge nozzle to be detachably arranged on the support frame, it is convenient to disassemble and clean the slurry discharge nozzle and to deeply clean the outlet position of the valve core after the cup body is disassembled, so as to achieve deep cleaning of the valve core, ensure the cleanliness of the valve core and the slurry discharge nozzle, and avoid the situation that the inside of both are not effectively cleaned, resulting in residual dirt inside, causing odor or even mold. At the same time, the axis of the valve core is located on the circle formed by the inner side wall of the positioning groove, and the axis of the slurry discharge nozzle is located on the circle formed by the inner side wall of the positioning protrusion, so that when the cup body is installed, the axis formed by the slurry discharge nozzle and the valve core can also realize radial center positioning of the cup body, further improving the coaxiality of the upper and lower couplings.

At the same time, the center of the circle formed by the inner wall of each layer of positioning protrusions is located on the axis of the lower coupling, so that the cup body can achieve coaxial cooperation with the support frame through multiple radial positioning, which can further enhance the coaxiality of the upper coupling and the lower coupling and ensure the stability of the transmission of the two.

[0013] In a preferred implementation of a food processing machine with precise positioning, the cup body includes a grinding cup with upper and lower openings, a heating plate arranged at the lower opening of the grinding cup, a cup seat and an outer shell.

At the same time, the outer shell includes a panel surrounding the cup seat and the outer side of the heating plate and a bottom cover fixed to the bottom of the heating plate. The panel is clamped and fixed between the bottom cover and the cup seat. Compared with the method of fixing the panel to the cup seat and then fixing the base to the outer shell, it not only reduces the dimension chain connecting the outer shell and the cup seat, but also avoids the situation of low coaxiality caused by too many assembly dimension chains, and can further improve the coaxiality of the whole machine. At the same time, it can also save assembly steps and connection parts, which can improve assembly efficiency and reduce production costs.

[0016] By setting the top wall of the positioning groove and the top wall of the positioning protrusion to abut against each other, and providing an avoidance gap between the enclosure and the support frame, the support frame and the enclosure do not participate in the assembly positioning, thereby further reducing the assembly tolerance chain of the participating mating parts, which is more conducive to the coaxiality of the cup body with the support seat after being installed in place, and further improving the stability of the upper and lower coupling transmission. It can also avoid the direct contact between the enclosure and the support frame, which causes the collision between the two and generates a large noise during food processing, which helps to reduce the generation of noise.

[0018] By providing the heating plate with a downwardly extending limit column and the bottom cover with a limit groove cooperating with the limit column, the positioning effect of the bottom cover and the heating plate is improved through the limiting cooperation of the limit column and the limit groove. At the same time, the center of the circle formed by the inner side walls of the plurality of limit columns is located on the axis of the upper coupling. As a result, when the bottom cover and the heating plate are assembled, the radial centering of the bottom cover and the heating plate can be achieved through the positioning of the limit column and the limit groove, thereby ensuring the coaxiality of the two, so that the lower coupling can still maintain the original axis after passing through the bottom cover, thereby further improving the coaxiality of the upper and lower couplings.

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0036] like Figures 1 to 8 As shown, the utility model provides a food processing machine with precise positioning, including a machine body, a cup body 1 arranged on the machine body and having a crushing chamber 111, a crushing device 2 arranged in the crushing chamber 111 and a motor 3 connected to the crushing device 2 in transmission. The machine body includes an outer shell 13, the cup body 1 is detachably arranged in the outer shell 13, a support frame 4 for fixing the motor 3 is provided below the cup body 1, an upper coupling 5 connected to the crushing device 2 in transmission is provided at the bottom end of the cup body 1, a lower coupling 6 matched with the upper coupling 5 in transmission is provided at the top of the support frame 4, and positioning structures matched with each other are also provided at the bottom end of the cup body 1 and the top end of the support frame 4, and a plurality of positioning structures are arranged at intervals along the circumference of the cup body 1 and the support frame 4, and the center of a circle formed by the plurality of positioning structures is located on the axis of the upper coupling 5 and the lower coupling 6.

[0037] The present application allows the cup body 1 to be detachably arranged in the housing 13, so that the user can replace different cup bodies 1 according to different usage requirements, such as the crushing cup 11, the dry grinding cup and the minced meat cup, so as to process different ingredients, thereby improving the user experience. At the same time, the bottom of the cup body 1 is provided with an upper coupling 5 that is transmission-connected to the crushing device 2, and the top of the support frame 4 is provided with a lower coupling 6 that is transmission-coordinated with the upper coupling 5, so that after the user installs the cup body 1 in the housing 13, the torque of the motor 3 can be transmitted through the cooperation of the upper and lower couplings 6 to ensure the normal operation of the crushing device 2. In addition, the bottom of the cup body 1 and the top of the support frame 4 are also provided with mutually cooperating positioning structures, and the positioning structures are arranged at intervals along the circumference of the cup body 1 and the support frame 4, so that the cup body 1 and the support frame 4 can improve the cooperation effect of the two with the help of the positioning cooperation of the positioning structure, ensure the stability of the connection and cooperation between the two, and avoid the situation where the two collide with each other and generate noise due to unstable cooperation, and there are multiple positioning structures, which can ensure that the positioning structure can realize the positioning of the two in multiple directions in the circumferential direction, further improving the positioning effect.

[0038] At the same time, the center of the circle formed by the multiple positioning structures is located on the axis of the upper coupling 5 and the lower coupling 6, so that after the cup body 1 is installed in place, with the help of the positioning structure, the cup body 1 and the support frame 4 are radially centered and positioned, so that the axis of the upper coupling 5 and the axis of the lower coupling 6 are colinear, thereby improving the coaxiality of the upper coupling 5 and the lower coupling 6, ensuring the stability of the transmission of the upper coupling 5 and the lower coupling 6 during torque transmission, especially when the crushing device 2 rotates at high speed, avoiding the low coaxiality of the upper and lower couplings 6 resulting in large vibration noise during transmission of the two, and even causing the crushing device 2 to fail in yaw transmission, thereby ensuring the stability of the whole machine operation.

[0039] It can be understood that the circle formed by multiple positioning structures in the present application can be a circle formed by the line connecting the axis of the positioning structure, or a circle formed by the line connecting the outer wall or the inner wall of the positioning structure. No specific limitation is made here. At the same time, the positioning structure is not limited to setting multiple ones, but can also be a semicircular or full circle structure, and the center of the circle is located on the axis of the upper and lower couplings 6, which will not be repeated here.

[0040] It should be noted that the present application does not specifically limit the positioning structure, which can be any one of the following embodiments:

[0041] Example 1: Figure 4 , Figure 5As shown, in this embodiment, the positioning structure includes a positioning groove 14 set at the bottom end of the cup body 1 and a positioning protrusion 41 set at the top of the support frame 4 and cooperating with the positioning groove 14. The center of the circle formed by the inner side walls of the plurality of positioning grooves 14 is located on the axis of the upper coupling 5, and the center of the circle formed by the inner side walls of the plurality of positioning protrusions 41 is located on the axis of the lower coupling 6. It can be understood that the circle formed by the inner side walls mentioned above is not formed by direct contact of the inner side walls, but is a circle formed by the inner side walls being arc-shaped and the extension line of the arc connecting the inner side walls.

[0042] By making the positioning structure include a positioning groove 14 set at the bottom end of the cup body 1 and a positioning protrusion 41 set at the top end of the support frame 4 and matched with the positioning groove 14, the user can improve the stability of the connection and matching between the two by means of the positioning and matching of the positioning groove 14 and the positioning protrusion 41 when installing the cup body 1. At the same time, the center of the circle formed by the inner side walls of the plurality of positioning grooves 14 is located on the axis of the upper coupling 5, and the center of the circle formed by the inner side walls of the plurality of positioning protrusions 41 is located on the axis of the lower coupling 6, so that after the cup body 1 is installed in place, the center of the circle formed by the arc surface of the positioning groove 14 and the positioning protrusion 41 is also located on the axis of the upper coupling 5 and the lower coupling 6, thereby ensuring the radial centering of the cup body 1 and the support frame 4, so that the upper coupling 5 and the lower coupling 6 are located on the same axis, and the coaxiality of the upper coupling 5 and the lower coupling 6 is further improved.

[0043] Furthermore, if Figure 3 , Figure 4 , Figure 5 As shown, the cup body 1 is provided with a drain port, and a drain valve is provided at the drain port. The drain valve includes a valve core 101 for controlling the opening and closing of the drain port and a slurry discharge nozzle connected to the valve core 101. The valve core 101 is detachable with the cup body 1, and the slurry discharge nozzle is detachably arranged on the support frame 4. The axis of the valve core 101 is located on the circle formed by the inner side wall of the positioning groove 14, and the axis of the slurry discharge nozzle is located on the circle formed by the inner side wall of the positioning protrusion 41.

[0044] By setting the valve core 101 to be detachable with the cup body 1, and the slurry discharge nozzle is detachably arranged on the support frame 4, it is convenient to disassemble and clean the slurry discharge nozzle and deeply clean the outlet position of the valve core 101 after the cup body 1 is disassembled, so as to achieve deep cleaning of the valve core 101, ensure the cleanliness of the valve core 101 and the slurry discharge nozzle, and avoid the situation that the inside of both cannot be effectively cleaned, resulting in residual dirt inside, causing them to produce odor or even mold. At the same time, the axis of the valve core 101 is located on the circle formed by the inner side wall of the positioning groove 14, and the axis of the slurry discharge nozzle is located on the circle formed by the inner side wall of the positioning protrusion 41, so that when the cup body 1 is installed, the axis formed by the slurry discharge nozzle and the valve core 101 can also realize radial center positioning of the cup body 1, further improving the coaxiality of the upper and lower couplings 6.

[0045] As a preference under this embodiment, multiple layers of positioning protrusions 41 are provided along the radial direction of the support frame 4 , and the center of the circle formed by the inner side walls of each layer of positioning protrusions 41 is located on the axis of the lower coupling 6 .

[0046] By providing multiple layers of positioning protrusions 41 along the radial direction of the support frame 4, the cup body 1 and the support frame 4 can further enhance their positioning through the cooperation of the multiple layers of positioning protrusions 41 and the positioning grooves 14, and further ensure the stability of the connection between the two. At the same time, the center of the circle formed by the inner wall of each layer of positioning protrusions 41 is located on the axis of the lower coupling 6, so that the cup body 1 can achieve coaxial cooperation with the support frame 4 through multiple radial positioning, which can further enhance the coaxiality of the upper coupling 5 and the lower coupling 6 and ensure the stability of the transmission between the two.

[0047] Preferably, if Figure 3 As shown, the inner wall of the positioning groove 14 is also provided with a vertical rib 141 extending axially, so that the vertical rib 141 can directly abut against the positioning protrusion 41 when the cup body 1 is installed, thereby ensuring the positioning effect and effectively avoiding inaccurate positioning caused by a gap between the two due to assembly and production errors.

[0048] Embodiment 2: In this embodiment, the cup body 1 is provided with a drain port, and a drain valve is provided at the drain port. The drain valve includes a valve core 101 for controlling the opening and closing of the drain port and a slurry discharge nozzle connected to the valve core 101. The valve core 101 is detachable with the cup body 1, and the slurry discharge nozzle is detachably arranged on the support frame 4. The axis of the valve core 101 is located on the circle formed by the axis of the upper coupler 9 and the axis of the water inlet head 10, and the axis of the slurry discharge nozzle is located on the circle formed by the axis of the lower coupler 7 and the axis of the water outlet head 8.

[0049] As a preferred implementation of the present application, Figure 1 As shown, the cup body 1 includes a grinding cup 11 with upper and lower openings, a heating plate 12 provided at the lower end opening of the grinding cup 11, a cup seat 15 and an outer shell 13. The cup seat 15 connects the grinding cup 11 and the heating plate 12 as a whole. The outer shell 13 is provided on the outside of the cup seat 15 and the heating plate 12. The outer shell 13 includes a surrounding plate 131 provided on the outside of the cup seat 15 and the heating plate 12 and a bottom cover 132 fixedly connected to the bottom end of the heating plate 12. The surrounding plate 131 is clamped and fixed between the bottom cover 132 and the cup seat 15.

[0050] By making the cup body 1 include a crushing cup 11 with upper and lower openings and a heating plate 12 provided at the lower opening of the crushing cup 11, when the user uses the food processor to process food, the heating of the heating plate 12 can be used to heat the food in the cup body 1, thereby meeting the user's usage needs. At the same time, the outer shell 13 includes a surrounding plate 131 surrounding the outer side of the cup seat 15 and the heating plate 12 and a bottom cover 132 fixedly connected to the bottom end of the heating plate 12. The surrounding plate 131 is clamped and fixed between the bottom cover 132 and the cup seat 15. Compared with the method of fixing the surrounding plate 131 to the cup seat 15 and then fixing the base to the outer shell 13, it not only reduces the dimension chain connecting the outer shell 13 and the cup seat 15, but also avoids the situation of low coaxiality caused by too many assembly dimension chains, and can further improve the coaxiality of the whole machine. At the same time, it can also save assembly steps and connection parts, which can improve assembly efficiency and reduce production costs.

[0051] Furthermore, if Figure 1 As shown, the positioning structure includes a positioning groove 14 set on the bottom cover 132 and a positioning protrusion 41 set on the top of the support frame 4 and cooperating with the positioning groove 14. The top wall of the positioning groove 14 abuts against the top wall of the positioning protrusion 41, and an avoidance gap is set between the enclosure 131 and the support frame 4.

[0052] By setting the top wall of the positioning groove 14 and the top wall of the positioning protrusion 41 to abut against each other, and providing an avoidance gap between the enclosing plate 131 and the support frame 4, the support frame 4 and the enclosing plate 131 do not participate in the assembly positioning, thereby further reducing the assembly tolerance chain of the participating mating parts, which is more conducive to the coaxiality of the cup body 1 with the support seat after being installed in place, and further improving the transmission stability of the upper and lower couplings 6. It can also avoid the situation where the enclosing plate 131 and the support frame 4 directly contact each other and cause the two to collide and generate a large noise during food processing, which helps to reduce the generation of noise.

[0053] As a preferred embodiment of this embodiment, Figure 6 , Figure 7 , Figure 8 As shown, the heating plate 12 is provided with a limiting column 121 extending downward, the bottom cover 132 is provided with a limiting groove 1321 cooperating with the limiting column 121, and multiple limiting columns 121 are provided along the circumference of the heating plate 12, and the center of the circle formed by the inner side walls of the multiple limiting columns 121 is located on the axis of the upper coupling 5.

[0054] By providing a downwardly extending limit column 121 on the heating plate 12 and providing a limit groove 1321 cooperating with the limit column 121, the bottom cover 132 and the heating plate 12 can enhance the positioning effect of the two through the limiting cooperation between the limit column 121 and the limit groove 1321. At the same time, the center of the circle formed by the inner side walls of the plurality of limit columns 121 is located on the axis of the upper coupling 5. Therefore, when the bottom cover 132 and the heating plate 12 are assembled, the radial centering of the bottom cover 132 and the heating plate 12 can be achieved through the positioning of the limit column 121 and the limit groove 1321, thereby ensuring the coaxiality of the two, so that the lower coupling 6 can still maintain the original axis after passing through the bottom cover 132, thereby further enhancing the coaxiality of the upper and lower couplings 6.

[0055] Furthermore, if Figure 7 , Figure 8 As shown, a positioning rib 13211 extending along an axis is further provided on the side wall of the limiting groove 1321 away from the center of the bottom cover 132 , and the positioning rib 13211 abuts against the limiting column 121 .
