In other embodiments, whipping cup 100 is integral with housing 300 in use, e.g., whipping cup 100 can be present as an integral part of housing 300 and removed only for servicing.
The whipping cup 100 is assembled from a cup body 110, a lid 120, and a base 130. The cup cover 120 can cover the upper part of the cup body 110; in use, the bottom of the cup holder 130 may be placed on top of the base 300. The cup body 110, the cup cover 120 and the cup base 130 together enclose a processing space 101 for accommodating and processing food materials. A whipping assembly having a whipping function and a heating assembly having a heating function are provided in the whipping cup 100. In operation, the whipping assembly and/or the heating assembly can process the food material. The interior of the cup holder 130 also includes a drive 230. A power drive 230 is connected to and provides a driving force to the whipping assembly.
When the whipping cup 100 is placed in the base 300, the cup holder 130 contacts the base 300. The lower end surface of the cup holder 130 and the upper end surface of the base 300 may be provided with conductive contacts coupled to each other. The conductive contacts may be conventional electrical connectors. The base 300 is provided therein with electronic components such as a power supply device and a controller. After the whipping cup 100 is placed on the base 300, the conductive contacts are connected, so that the whipping cup 100 and the base 300 are electrically and physically connected, and the power supply device and the controller 130 disposed in the base 300 can respectively provide power and signal control support for the power driving device 230, the heating component and other working elements disposed in the whipping cup 100.
The power supply device may be a battery or the like built in the base 300, or may be a wire or the like for electrically connecting an external power source.
The power drive device 230 includes a motor 231 and a fan 233. The motor 231 has a drive shaft 232. Wherein the motor 231 is electrically connected to the power supply device and rotates upon being energized. The driving shaft 232 is fixed to a rotor of the motor 231 and rotates synchronously with the motor 231. The top end of drive shaft 232 extends toward processing space 101 and is fixedly attached to the whipping assembly in whipping cup 100 to rotate the whipping assembly. The tail end of the driving shaft 232 extends towards the direction close to the bottom of the food processor 10, extends out of the motor 231 and is connected with the fan 233 to drive the fan 233 to rotate, so that the air flow is accelerated, and the heat dissipation and the temperature reduction of the motor 231 are realized.
The cup holder 130 includes a main body 211, a fixing bracket 212, and a stopper 213. A swing stopper 2121. The large body 211 is fixedly coupled to the cup body 110, and the large body 211 forms a working space for accommodating the power driving means 230 and the like. The fixed bracket 212 is fixedly connected to the large body 211; the fixing bracket 212 is sleeved outside the motor 231, and is used for fixing or mounting the motor 231 in the power driving device 230.
The limiting member 213 includes a swing limiting portion 2121 for limiting the driving shaft 233 to swing in the radial direction. A radial stopper 2122 extends from the swing stopper 2121 in a direction toward the cutter 142. The limiting member 213 is sleeved outside the driving shaft 232, in other words, the radial limiting portion 2122 and the swing limiting portion 2121 are sleeved outside the driving shaft 232. A limit bearing 2123 is provided between the swing limit portion 2121 and the drive shaft 232. In other words, the wobble stopper 2121 is coupled to the drive shaft 232 via the stopper bearing 2123, and the wobble stopper 2121 can position the drive shaft 232 in a predetermined radial direction. The radial stopper 2122 extends from the swing stopper 2121 in a direction approaching the cutter 142, and forms a stopper space 2124.
Located within whipping cup 100 is a cutter assembly 140. The bottom of whipping cup 100 is provided with a heating disk 150. Wherein, the heating plate 150 is at least part of the heating assembly and is fixed on the cup holder 130. The heating plate 150 can be closely attached to the bottom surface of the cup body 110. Alternatively, the heating plate 150 can be an integral part of the bottom surface of the cup 110. The heating plate 150 realizes heating of the food material located in the processing space 101 by changing its own temperature.
As shown in fig. 1-3, whipping cup 100 further includes a knife block 160. The heating plate 150 is provided with a through positioning hole 151, and the tool holder 160 is disposed through the positioning hole 151 and fixedly connected to the heating plate 150. In addition, the tool apron 160 is further sleeved outside the rotating shaft 141 and the driving shaft 232 to limit the rotating shaft 141 and the driving shaft 232 in the radial direction. A positioning bearing 171 and an oil seal 172 are installed in the gap between the tool holder 160 and the driving shaft 232, so that the tool assembly 140 can work normally, the food material in the processing space 101 can be prevented from leaking into the cup 130, and the power driving device 230, the power supply device and other components in the cup 130 can work normally.
When the food processor 10 stirs the food material, the motor 231 drives the driving shaft 232 to rotate at a high speed. Since the fan 233 is connected to the rear end of the driving shaft 232, the fan 233 flows around during rotation, and the fan 233 swings in the radial direction under the reaction force of the air, so that the driving shaft 232 swings in the radial direction. Therefore, the end of the driving shaft 232 connecting the tool holder 160 and the rotating shaft 141 can swing radially, so that the tool 142 in the tool assembly 140 swings during the process of stirring the food material, which affects the stability of the operation. In one design, as shown in fig. 4, the motor 231 is limited only by the fixed bracket 212, and the drive shaft 232 is preliminarily positioned by the swing limiting portion 2121. The holder 160 is spaced apart from the swing stopper 2121, and the holder 160 is only fixedly connected to the heating plate 150. The tool holder 160 is sleeved on the driving shaft 232 and the rotating shaft 141 through a positioning bearing 171 and an oil seal 172, and the tool holder 160 cannot better limit the swing of the driving shaft 232 in the radial direction. Meanwhile, the swing limiting portion 2121 cannot obtain an effective limiting force, and therefore, the driving shaft 232 cannot be better limited from swinging in the radial direction. However, once the driving shaft 232 is swung, the positioning bearing 171 and the oil seal 172 between the tool holder 160 and the driving shaft 232 cannot bear the pressing force due to the swing of the driving shaft 232 during a long-term use. The positioning bearing 171 is typically a ball bearing, and the balls inside the positioning bearing are easily deformed under the action of the extrusion force, thereby affecting the rotation of the whipping assembly. Meanwhile, the oil seal 172 is also deformed under the condition of being subjected to extrusion force, so that the sealing effect of the lubricating oil is affected. Damage to the positioning bearing 171 and the oil seal 172 may also cause water seepage and electric leakage, affect the normal operation of the components such as the power driving device 230 in the cup holder 130, and affect the safety of the food processor 10 and the life of the components.
As shown in fig. 1 to 3, in the present embodiment, the tool holder 160 includes a main body 161 and a positioning portion 162 connected to the main body. The cutter member 140 is rotatably mounted to the body portion 161. The positioning portion 162 of the tool holder 160 is inserted into and fixed to the positioning hole 151 of the heating plate 150, and the positioning portion 162 is close to the base 300.
In the present embodiment, the radial stopper 2122 is fixed to the positioning portion 162 and is used to limit the radial swing of the driving shaft 232.
In the above arrangement, the positioning portion 162 of the tool holder 160 is fixedly connected to the radial limiting portion 2122 to radially position the driving shaft 232, so as to prevent or reduce the radial swing of the driving shaft 232 of the motor 231 and/or the rotating shaft 141 of the tool assembly 140, and thus prevent or reduce the radial deformation damage of the positioning bearing 171 and the oil seal 172 due to excessive stress. Thus, the effect of motor 231 driving shaft 232 and/or rotating shaft 141 of cutter assembly 140 on the rotation of cutter assembly 140 during long-term rotation is avoided or reduced. Meanwhile, the sealing relationship between the cup body 110 and the cup base 130 of the whipping cup 100 is ensured, the food material in the processing space 101 is prevented from permeating into the cup base 130, the electric leakage phenomenon is avoided, the stability and the safety of the food processor 10 are improved, and the service life of the food processor 10 is prolonged. In addition, the sealing of the lubricating oil can be ensured, and the leakage of the lubricating oil can be prevented.
Further, in the present embodiment, the radial stopper portion 2122 encloses a stopper space 2124. The positioning portion 162 is provided in the stopper space 2124, and is configured to limit the radial swing of the drive shaft 232 by the radial stopper portion 2122 and the swing stopper portion 2121. Specifically, the side of the positioning portion 162 away from the cutter 142 extends out of the heating plate 150 and into the limiting space 2124, so as to be fixed to the radial limiting portion 2122. Of course, in other embodiments, the side of the positioning portion 162 away from the cutter 142 may extend out of the heating plate 150 and form a limiting groove, and the radial limiting portion 2122 extends from the swing limiting portion 2121 toward the cutter holder 142 and extends into the limiting groove, so as to be fixed to the positioning portion 162.
In the above arrangement, since the heating plate 150 has high strength and rigidity, the driving shaft 232 is secondarily positioned in the radial direction by the fixing relationship between the positioning portion 162 fixed in the tool rest 160 of the heating plate 150 and the radial direction restricting portion 2122, which is more favorable for restricting the swing of the driving shaft 232 in the radial direction.
In the present embodiment, the radial stopper portion 2122 is fixedly connected to the fixed bracket 212 via the swing stopper portion 2121. In other words, the limiting member 213 is fixedly connected to the fixing bracket 212. With the above arrangement, the radial stopper portion 2122 and the wobble stopper portion 2121 can also radially restrict the driving shaft 232 by the force provided by the fixing bracket 212. Further, as shown in fig. 5 and 6, the radial dimension of the positioning portion 162 corresponds to the radial dimension of the limiting space 2124. In the present embodiment, the positioning portion 162 and the radial limiting portion 2122 are both annular, and the outer diameter of the positioning portion 162 is the same as the inner diameter of the radial limiting portion 2122.
In the above arrangement, the positioning portion 162 and the stopper space 2124 having the same radial dimension are matched, and the positioning portion 162 and the radial stopper portion 2122 do not generate a pressing force due to interference fit, thereby protecting the structures of the tool holder 160, the swing stopper portion 2121, the radial stopper portion 2122, the positioning bearing 171, and the like. Meanwhile, the positioning portion 162 and the radial stopper portion 2122 do not affect the radial limiting action on the driving shaft 232 due to an excessive gap therebetween. With the above arrangement, the wobble stopper portion 2121 and the radial stopper portion 2122 are enabled to better restrict the wobble of the drive shaft 232 in the radial direction.
Further, the depth of the positioning portion 162 entering the limiting space 2124 is greater than or equal to 1.5 mm. Specifically, the depth of the positioning part 162 entering the limiting space 2124 is defined as a first depth L1, and the first depth L1 is greater than or equal to 1.5 mm. The positioning part 162 located in the position-limiting space 2124 can limit the radial swing of the radial position-limiting part 2122 by the force provided by the heating plate 150. The radial stopper 2122 in turn can limit the radial swing of the driving shaft 232. By limiting the depth of the positioning portion 162 located in the limiting space 2124, the effective contact area between the tool holder 160 and the radial limiting portion 2122 can be ensured, so that the positioning portion 162 can apply an effective limiting force to the swing limiting portion 2121 to limit the swing thereof in the radial direction. Through a lot of experiments, when the first depth is greater than or equal to 1.5 mm, the positioning portion 162 can apply a limiting force to the radial limiting portion 2122 to effectively limit the radial swinging of the radial limiting portion, so as to better avoid or reduce the radial swinging of the driving shaft 232. Through the setting, further guarantee cutter unit 140's stable rotation, guaranteed the sealed relation between the cup 110 of whipping cup 100 and cup base 130, promoted the stability and the security of cooking machine, guaranteed cooking machine's life. In addition, the sealing of the lubricating oil can be ensured, and the leakage of the lubricating oil can be prevented.
Further, the wobble stopper portion 2121 is rotatably provided in the wobble stopper portion 2121 by the stopper bearing 2123 with respect to the drive shaft 232, in other words, the wobble stopper portion 2121 radially positions the drive shaft 232 by the stopper bearing 2123. The swing stopper 2121 having a large thickness can provide a large stopper force to the drive shaft 232 via the stopper bearing 2123. In the present embodiment, the wall thickness d1 of the swing stopper 2121 is 2 mm or more and 5 mm or less. Through a plurality of experiments, it is shown that when the wall thickness d1 of the swing stopper 2121 is within the above range, the swing stopper 2121 can effectively position the stopper bearing 2123 and the drive shaft 232 in the radial direction, thereby preventing or reducing the swing of the drive shaft 232 in the radial direction. Meanwhile, the strength of the swing limiting portion 2121 can be ensured, and cracks and the like in the swing limiting portion are avoided.
In the present embodiment, the wall thickness d2 of the radial stopper portion 2122 is smaller than the wall thickness d1 of the wobble stopper portion 2121, and the wall thickness d2 of the radial stopper portion 2122 is 1.5 mm or more and 2 mm or less. Through a plurality of experiments, it is shown that when the wall thickness d2 of the radial limiting portion 2122 is within the above range, the radial limiting portion 2122 can effectively limit the driving shaft 232, so as to better avoid or reduce the swing of the driving shaft 232 in the radial direction. Meanwhile, the radial limiting portion 2122 can have a certain strength to receive the limiting force applied thereto by the positioning portion 162 of the tool holder 160, thereby avoiding the occurrence of cracks therein.
As shown in fig. 6, referring to fig. 1 as necessary, the swing stopper 2121 includes a stopper end plate 2127, and the stopper end plate 2127 extends from an outer edge of the swing stopper 2121 toward the axial direction close to the drive shaft 232. The limiting end plate 2127 is sleeved outside the driving shaft 232 and is in a circular ring shape. The radial stopper 2122 is provided on the stopper end plate 2127. The limit end plate 2127 also serves to axially position a limit bearing 2123 disposed between the drive shaft 232 and the wobble limit portion 2121. The stopper end plate 2127 may fix the radial stopper portion 2122.
The end surface of the positioning portion 162 far from the whipping cup 100 is a first limit end surface 1621, and the end surface of the limit end plate 2127 close to the cutter 142 is a second limit end surface 2125. In the manufacturing process, in order to reduce the process flow and the manufacturing cost, the first stopper end surface 1621 of the positioning portion 162 and the second stopper end surface 2125 of the radial stopper portion 2122 are not subjected to a finish machining process, and the surface roughness thereof is large. If the first limiting end surface 1621 is attached to the second limiting end surface 2125 in order to utilize the larger limiting acting force provided by the contact between the first limiting end surface 1621 and the second limiting end surface 2125, the first limiting end surface 1621 and the second limiting end surface 2125 are easy to contact with each other in a point and/or line due to the larger surface roughness of the first limiting end surface 1621 and the second limiting end surface 2125. In this case, not only the surface contact between the swing limiting portion 2121 and the radial limiting portion 2122 cannot be realized, but also the tool holder 160 cannot provide effective limiting force for the radial limiting portion of the swing limiting portion 2121 and the radial limiting portion 2122; meanwhile, under the action of long-time contact and force application, the first limiting end surface 1621 and the second limiting end surface 2125 are worn, and even more, the tool apron 160, the swing limiting portion 2121 and the radial limiting portion 2122 may be damaged due to local large stress.
In this embodiment, in order to avoid the above phenomenon, the first limiting end surface 1621 and the second limiting end surface 2125 are disposed at an interval. Through the above arrangement, the end surface of the positioning portion 162 having a relatively large surface roughness, which is far away from the whipping cup 100, and the end surface of the radial limiting portion 2122, which is far away from the cup holder 130, are prevented from point contact or line contact, so that the structural stability of the cutter holder 160, the swing limiting portion 2121, and the radial limiting portion 2122 is ensured. Meanwhile, the process flow and the manufacturing cost are saved.
In this embodiment, the minimum distance between the first limiting end surface 1621 and the second limiting end surface 2125 is greater than or equal to 0.2 mm and less than or equal to 0.4 mm. Through the above arrangement, the minimum distance between the first limiting end face 1621 and the second limiting end face 2125 is limited, so that the contact between the first limiting end face 1621 and the second limiting end face 2125 can be avoided, and meanwhile, the depth of the positioning portion 162 located in the limiting space 2124 can be ensured, thereby ensuring the limiting effect of the swinging limiting portion 2121 and the radial limiting portion 2122 on the driving shaft 232.
Further, in the present embodiment, the radial stopper portion 2122 is integrally formed with the wobble stopper portion 2121. In other words, the stopper 213 is an integrally molded component. Through the above arrangement, the fixed connection between the radial limiting portion 2122 and the swing limiting portion 2121 is facilitated, and meanwhile, the strength of the swing limiting portion 2121 and the strength of the radial limiting portion 2122 are ensured.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above embodiments, but not to limit the present invention, any person skilled in the art can make modifications or changes to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
