Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine which is easy to clean. Background Art

[0002] Existing food processing machines, such as meat grinders, usually include a main unit with a built-in motor and a cup body assembly arranged below the main unit, the cup body assembly includes a cup body with a crushing device installed therein and a cup cover arranged on the top of the cup body, the crushing device is transmission-connected to the motor, and when using the food processor, the user places the food in the cup body, then closes the cup cover on the top of the cup body, and installs the main unit on the cup cover, and the motor drives the crushing device to rotate to process the food, but different food ingredients have different requirements on the rotation speed of the crushing device. For example, when the user needs to grind meat, the crushing device needs to rotate in the cup body in a high-speed and low-torque motion form to grind the meat; when the user needs to knead dough, the crushing device needs to rotate in the cup body in a low-speed and high-torque motion form to knead the dough.

[0003] In order to meet the different usage requirements of users, for example, Chinese utility model patent CN217937989U discloses a food processing machine with good noise reduction effect, which is concave at the bottom of the casing to form an installation cavity, and a detachable reduction box is embedded in the installation cavity, the input end of the reduction box is transmission-connected with the output end of the motor, and the output end of the reduction box is transmission-connected with the stirring element. When the user needs the crushing device to output high speed and low torque, the motor is directly transmission-connected with the crushing device. When the user needs the crushing device to output low speed and high torque, the reduction box is installed in the installation cavity, and the motor transmits the torque to the crushing device after the reduction of the reduction box. Although the above-mentioned food processing machine can meet the different outputs of the speed and torque of the crushing device under different working conditions, because the installation cavity only realizes the positioning of part of the reduction box, the connection and matching stability between the reduction box and the main machine is low, especially when in the working state, which will cause the reduction box and the main machine to have relative displacement, resulting in unstable transmission or even stuck. In order to achieve the installation of the lower part of the reduction gearbox, it is necessary to set a multi-level accommodating cavity on the cup cover to match the bottom surface of the reduction gearbox and the bottom surface of the main unit, so that the cup cover forms multiple steps, resulting in cleaning dead corners, increasing the difficulty of cleaning, and seriously affecting the consumer experience. Utility Model Content

[0004] The purpose of the utility model is to provide a food processing machine that is easy to clean, so as to solve the problems that the connection between the reducer box and the cup body of the existing food processing machine is unstable, resulting in displacement and unstable transmission, and the cup cover is provided with a multi-level accommodating cavity to distribute and adapt the bottom surface of the reducer box and the bottom surface of the main body to form multiple steps, which makes cleaning difficult.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine that is easy to clean, including a main unit with a built-in motor and a cup body assembly arranged below the main unit, the cup body assembly including a cup body with a crushing device therein and a cup cover arranged above the cup body, the crushing device is connected to the motor in a transmission manner, an inwardly concave mounting groove is provided at the bottom of the main unit, a detachable reduction box is provided in the mounting groove, the crushing device can be connected to the motor in a transmission manner through the reduction box, the bottom surface of the outer shell of the reduction box is arranged not lower than the bottom surface of the shell of the main unit, and the cup cover is provided with a accommodating groove for accommodating the main unit and the reduction box, and the bottom surface of the accommodating groove is a plane.

[0006] The present application provides a detachable reduction box in the installation slot of the host, and the crushing device can be connected to the motor through the reduction box, so that when the user uses the food processor to process food, the motor can be directly connected to the crushing device through the motor to obtain a faster speed, and the motor can be decelerated by the reduction box and then connected to the crushing device to obtain a greater torque, so that the user can process different food materials according to their needs, and the functions of the food processor are more diversified, which improves the user experience. At the same time, the bottom surface of the reduction box shell is not lower than the bottom surface of the shell of the host, so that the reduction box shell can be completely accommodated in the installation slot, which helps to improve the reliability of the installation slot to fix the reduction box, improve the reliability of the torque transmission of the reduction box, avoid the situation where the reduction box is displaced due to the unstable cooperation between the reduction box and the installation slot, resulting in unstable transmission or even stuck, and improve the stability of torque transmission. In addition, the cup cover is provided with a receiving groove for accommodating the main unit and the reduction gearbox, and the bottom surface of the receiving groove is a plane. Compared with the existing method of requiring another groove to be provided on the cup cover to accommodate part of the reduction gearbox, it effectively avoids the formation of multiple steps by providing grooves on the top surface of the cup cover, resulting in an increase in dead corners for cleaning the cup cover, making it difficult for users to clean, thereby facilitating users to clean the cup cover and improving the cleanliness of the cup cover.

[0007] In a preferred implementation of a food processor that is easy to clean, the bottom surface of the housing of the reduction gearbox is arranged flush with the bottom surface of the housing of the main machine.

[0008] By setting the bottom surface of the reduction box shell flush with the bottom surface of the main machine shell, the installation groove can fix the reduction box while avoiding the situation where the axial height of the installation groove is too large compared to the height of the reduction box shell, resulting in the installation groove occupying a large space, causing the entire main machine structure to be not compact, which helps to improve the compactness of the main machine and reduce its occupied space. At the same time, it can also avoid the formation of a cleaning dead angle between the side wall of the installation groove and the reduction box shell, which makes it easy for dirt to enter the interior and make it difficult to clean, thereby further ensuring the cleanliness of the entire machine.

[0009] In a preferred implementation of a food processor that is easy to clean, the bottom surface of the accommodating groove is arranged to fit the bottom surfaces of the reduction gearbox housing and the main machine housing.

[0010] By fitting the bottom surface of the accommodating groove with the bottom surfaces of the reduction gearbox housing and the main engine housing, the reduction gearbox can be fixed by the mounting groove while also being axially supported and limited by the bottom surface of the accommodating groove, thereby further enhancing the supporting and limiting effect of the cup cover on the reduction gearbox and the entire main engine, thereby improving the stability of the entire machine and further avoiding the situation where the reduction gearbox is unstable and displaced, resulting in unstable transmission.

[0011] In a preferred implementation of a food processor that is easy to clean, the bottom surface of the reduction gearbox shell is higher than the bottom surface of the main machine shell, so that the reduction gearbox is embedded in the installation groove, and the inner bottom surface of the accommodating groove supports the bottom surface of the main machine shell.

[0012] By making the bottom surface of the reduction box shell higher than the bottom surface of the main unit shell, so that the reduction box can be embedded in the installation groove, it helps to further enhance the limiting and fixing effect of the installation groove on the reduction box, ensure its position stability, and further enhance the reliability of the transmission. At the same time, the noise generated by the reduction box during the transmission process can also be reduced in the installation groove, which helps to reduce the propagation of noise outward and enhance the noise reduction effect. In addition, the inner bottom surface of the receiving groove supports the bottom surface of the main unit shell, ensures the positioning effect of the cup cover on the main unit, enhances the stability of the main unit position, avoids the shaking of the main unit causing unstable transmission or even transmission failure, and further enhances the stability of the transmission.

[0013] In a preferred implementation of a food processor that is easy to clean, a micro switch and a first switch connecting rod are provided in the main machine, a second switch connecting rod is provided in the reduction gear box, and the food processor has a first working state in which the top end of the crushing device is transmission-connected to the bottom end of the reduction gear box, and the top end of the reduction gear box is transmission-connected to the output end of the motor. When in the first working state, the second switch connecting rod drives the first switch connecting rod to move toward the micro switch to trigger the micro switch.

[0014] By arranging a micro switch and a first switch connecting rod in the main machine, and a second switch connecting rod in the reduction box, when the user needs to obtain a larger torque when using the food processor, the reduction box is installed in the installation slot and the large torque is transmitted through the connection between the reduction box and the crushing device, thereby meeting the user's use needs. At the same time, when in the first working state, the second switch connecting rod drives the first switch connecting rod to move toward the micro switch to trigger the micro switch, ensuring that the main machine can only be started when the reduction box is installed in place, avoiding the situation where the main machine can be started without the reduction box being installed in place, resulting in the jamming of the transmission connection between the reduction box and the main machine, the wear of parts and the generation of abnormal noise, further improving the stability of the transmission, and reducing the generation of noise.

[0015] In a preferred implementation of a food processor that is easy to clean, the reduction box includes a body and an output shaft disposed at the bottom end of the body, and the bottom end of the output shaft is disposed no lower than the bottom end of the mounting groove.

[0016] By setting the bottom end of the output shaft to be not lower than the bottom end of the mounting groove, the output shaft can also be hidden in the mounting groove, and then the entire reduction gearbox is hidden in the mounting groove, so that when the main machine is detached from the cup body and placed separately, the main machine can be placed directly and stably on the desktop with the bottom facing downward, thereby effectively avoiding the situation where the output shaft protrudes from the bottom end of the mounting groove, causing the user to remove the reduction gearbox from the main machine or place it horizontally when placing the main machine, which helps to improve the convenience of user operation.

[0017] In a preferred implementation of a food processor that is easy to clean, the bottom wall of the accommodating groove is provided with a limiting rib extending upward, and the main machine includes a bottom wall located outside the mounting groove, and the bottom wall is provided with a mounting groove that cooperates with the limiting rib.

[0018] By providing the bottom wall of the receiving groove with a limiting rib extending upward, and the main machine including a bottom wall located outside the installation groove, and a limiting groove on the bottom wall that cooperates with the limiting rib, the main machine and the cup cover can be prevented from rotating after the main machine is installed in place through the limiting cooperation between the limiting rib and the limiting groove, ensuring that the main machine can achieve torque transmission during the transmission process while avoiding relative rotation between the main machine and the cup body, thereby improving the working stability. At the same time, the limiting rib and the limiting groove are arranged at the relative outside of the whole machine, so that the main machine can be better aligned when it is installed, which helps to improve the assembly efficiency.

[0019] In a preferred implementation of a food processor that is easy to clean, a micro switch and a first switch connecting rod are provided in the main machine, one end of the first switch connecting rod cooperates with the micro switch, and the other end extends from the limit groove. The food processor has a second working state in which the motor directly drives the crushing device to rotate. When in the second working state, the limit rib drives the first switch connecting rod and triggers the micro switch.

[0020] By matching one end of the first switch link with the micro switch and the other end extending from the limit slot, the structure of providing a notch on the bottom wall to expose the first switch link is omitted, and the structure of providing a convex rib on the bottom wall of the receiving slot to drive the first switch link is omitted, so that the limit slot and the limit rib can provide triggering for the micro switch while achieving the limit, thereby improving its function. It can also reduce the situation where the user is difficult to clean due to too many convex ribs in the receiving slot, which helps to further improve the convenience of cleaning the cup cover.

[0021] In a preferred implementation of a food processor that is easy to clean, the cup cover also includes a through hole for the top end of the crushing device to extend out, and a rib arranged around the through hole is provided between the outer side of the through hole and the limiting rib, and the rib supports the bottom wall of the reduction box.

[0022] By providing surrounding ribs arranged around the through hole between the outer side of the through hole and the limiting ribs, the surrounding ribs support the bottom wall of the reduction box, further enhancing the supporting and limiting effect of the accommodating groove on the reduction box, thereby further enhancing the stability of the connection between the reduction box and the main engine, avoiding the situation where the reduction box and the installation groove are unstable, causing displacement of the reduction box, resulting in unstable transmission or even jamming, and improving the stability of torque transmission.

[0023] In a preferred implementation of a food processor that is easy to clean, one of the side wall of the reduction box and the side wall of the mounting groove is provided with a screw buckle, and the other of the two is provided with a screw groove that matches the screw buckle.

[0024] By providing a turn buckle on one of the side wall of the reduction box and the side wall of the installation groove, and providing a rotation groove that cooperates with the turn buckle on the other of the two, the reduction box and the installation groove can be connected and cooperated through the limiting of the turn buckle and the rotation groove, which can not only provide circumferential anti-rotation limit, but also provide axial limit for the reduction box, further enhance the limiting effect of the installation groove on the reduction box, ensure the reliability of the position of the reduction box, and further ensure the stability of the operation of the whole machine.

[0033] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. 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.

[0034] like Figures 1 to 4 As shown, the utility model provides a food processing machine which is easy to clean, comprising a main unit 1 with a built-in motor 11 and a cup body 2 assembly arranged below the main unit 1, the cup body 2 assembly comprising a cup body 2 with a crushing device 4 therein and a cup cover 3 arranged above the cup body 2, the crushing device 4 is transmission connected to the motor 11, an inwardly concave mounting groove 12 is provided at the bottom of the main unit 1, a detachable reduction box 5 is provided in the mounting groove 12, the crushing device 4 can be transmission connected to the motor 11 through the reduction box 5, the bottom surface of the outer shell of the reduction box 5 is not lower than the bottom surface of the shell of the main unit 1, and the cup cover 3 is provided with a receiving groove 31 for accommodating the main unit 1 and the reduction box 5, and the bottom surface of the receiving groove 31 is a plane.

[0035] The present application provides a detachable reduction box 5 in the mounting groove 12 of the main machine 1, and the crushing device 4 can be connected to the motor 11 through the reduction box 5, so that when the user uses the food processor to process food, the motor 11 can be directly connected to the crushing device 4 through the motor 11 to obtain a faster rotation speed, and the motor 11 can be connected to the crushing device 4 after being decelerated by the reduction box 5 to obtain a greater torque, so that the user can process different food materials according to their needs, and the functions of the food processor are more diversified, which improves the user experience. At the same time, the bottom surface of the outer shell of the reduction box 5 is not lower than the bottom surface of the shell of the main machine 1, so that the outer shell of the reduction box 5 can be completely accommodated in the mounting groove 12, which helps to improve the reliability of the fixing of the mounting groove 12 to the reduction box 5, improve the reliability of the torque transmission of the reduction box 5, avoid the situation where the reduction box 5 is displaced due to the unstable cooperation between the reduction box 5 and the mounting groove 12, resulting in unstable transmission or even stuck, and improve the stability of torque transmission. In addition, the cup cover 3 is provided with a receiving groove 31 for accommodating the main unit 1 and the reduction box 5. The bottom surface of the receiving groove 31 is a plane. Compared with the existing method of providing another groove on the cup cover 3 to accommodate part of the reduction box 5, it effectively avoids the situation that the grooves on the top surface of the cup cover 3 form multiple steps, which increases the dead corners of the cup cover 3 for cleaning and makes it difficult for users to clean. It is convenient for users to clean the cup cover 3 and improves the cleanliness of the cup cover 3. It should be noted that the structure of the crushing device 4 in the present application is not specifically limited. It can be a meat grinder, a crushing knife, a dough kneading knife, etc. Users can install different crushing devices 4 into the cup body 2 according to different usage requirements.

[0036] It should be noted that the present application does not specifically limit the relative relationship between the reduction box 5 and the main engine 1, which can be any one of the following embodiments:

[0037] Example 1: Figure 2 As shown, in this embodiment, the bottom surface of the housing of the reduction box 5 is arranged flush with the bottom surface of the housing of the main machine 1.

[0038] By setting the bottom surface of the outer shell of the reduction box 5 flush with the bottom surface of the outer shell of the main machine 1, the installation groove 12 can fix the reduction box 5 while avoiding the situation that the axial height of the installation groove 12 is too large compared to the height of the reduction box 5 outer shell, resulting in the installation groove 12 occupying a large space, causing the structure of the entire main machine 1 to be not compact, which helps to improve the compactness of the main machine 1 and reduce its occupied space. At the same time, it can also avoid the formation of a cleaning dead corner between the side wall of the installation groove 12 and the outer shell of the reduction box 5, which makes it easy for dirt to enter the interior and make it difficult to clean, thereby further ensuring the cleanliness of the entire machine.

[0039] Furthermore, if Figure 2 As shown, the bottom surface of the accommodating groove 31 is arranged to fit with the bottom surface of the outer shell of the reduction box 5 and the outer shell of the main machine 1 .

[0040] By fitting the bottom surface of the accommodating groove 31 with the bottom surface of the outer shell of the reduction box 5 and the outer shell of the main unit 1, the reduction box 5 can be fixed by the mounting groove 12 while also being axially supported and limited by the bottom surface of the accommodating groove 31, thereby further enhancing the supporting and limiting effect of the cup cover 3 on the reduction box 5 and the entire main unit 1, thereby improving the stability of the entire machine and further avoiding the situation where the reduction box 5 is unstable and displaced, resulting in unstable transmission.

[0041] Embodiment 2: In this embodiment, the bottom surface of the outer shell of the reduction box 5 is higher than the bottom surface of the outer shell of the main machine 1, so that the reduction box 5 is embedded and installed in the installation groove 12, and the inner bottom surface of the accommodating groove 31 supports the bottom surface of the outer shell of the main machine 1.

[0042] By making the bottom surface of the outer shell of the reduction box 5 higher than the bottom surface of the outer shell of the main unit 1, so that the reduction box 5 is embedded and installed in the installation groove 12, it is helpful to further enhance the limiting and fixing effect of the installation groove 12 on the reduction box 5, ensure the stability of its position, and further enhance the reliability of the transmission. At the same time, the noise generated by the reduction box 5 during the transmission process can also be reduced in the installation groove 12, which helps to reduce the propagation of the noise outward and enhance the noise reduction effect. In addition, the inner bottom surface of the accommodating groove 31 supports the bottom surface of the outer shell of the main unit 1, ensures the positioning effect of the cup cover 3 on the main unit 1, enhances the stability of the position of the main unit 1, avoids the shaking of the main unit 1 causing unstable transmission or even transmission failure, and further enhances the stability of the transmission.

[0043] As a preferred embodiment of the present application, a micro switch and a first switch connecting rod are provided in the main unit 1, a second switch connecting rod is provided in the reduction gear box 5, and the food processor has a first working state in which the top end of the crushing device 4 is transmission-connected to the bottom end of the reduction gear box 5, and the top end of the reduction gear box 5 is transmission-connected to the output end of the motor 11. When in the first working state, the second switch connecting rod drives the first switch connecting rod to move toward the micro switch to trigger the micro switch.

[0044] By arranging a micro switch and a first switch connecting rod in the main machine 1, and a second switch connecting rod in the reduction box 5, when the user needs to obtain a larger torque when using the food processor, the reduction box 5 is installed in the installation groove 12 and the large torque is transmitted through the connection between the reduction box 5 and the crushing device 4, thereby meeting the user's use needs. At the same time, when it is in the first working state, the second switch connecting rod drives the first switch connecting rod to move toward the micro switch to trigger the micro switch, ensuring that the main machine 1 can only be started when the reduction box 5 is installed in place, avoiding the situation where the main machine 1 can be started without the reduction box 5 being installed in place, resulting in the jamming of the transmission connection between the reduction box 5 and the main machine 1, the wear of parts and the generation of abnormal noise, further improving the stability of the transmission, and reducing the generation of noise.

[0045] It should be noted that the present application does not specifically limit the relative relationship between the reduction box 5 and the mounting groove 12. As a preferred embodiment of the present application, the reduction box 5 includes a main body 51 and an output shaft 52 arranged at the bottom end of the main body 51. The bottom end of the output shaft 52 is not lower than the bottom end of the mounting groove 12. More preferably, the bottom end of the output shaft 52 is flush with the bottom end of the mounting groove 12.

[0046] By setting the bottom end of the output shaft 52 to be not lower than the bottom end of the mounting groove 12, the output shaft 52 can also be hidden in the mounting groove 12, and the entire reduction box 5 is hidden in the mounting groove 12, so that when the main unit 1 is detached from the cup body 2 and placed separately, the main unit 1 can be placed directly and stably on the desktop with the bottom facing down, thereby effectively avoiding the situation where the output shaft 52 protrudes from the bottom end of the mounting groove 12, causing the user to remove the reduction box 5 from the main unit 1 or place it horizontally when placing the main unit 1, which helps to improve the convenience of user operation.

[0047] As a preferred embodiment of the present application, Figure 2 , Figure 3 As shown, the bottom wall of the receiving groove 31 is provided with a limiting rib 312 extending upward, and the host 1 includes a bottom wall located outside the installation groove 12, and the bottom wall is provided with an installation groove 12 that cooperates with the limiting rib 312 to limit the position.

[0048] By providing the bottom wall of the receiving groove 31 with a limiting rib 312 extending upward, and the main machine 1 including a bottom wall located outside the installation groove 12, and a limiting groove that cooperates with the limiting rib 312, the main machine 1 and the cup cover 3 are prevented from rotating after the main machine 1 is installed in place through the limiting cooperation between the limiting rib 312 and the limiting groove, ensuring that the main machine 1 and the cup body 2 are prevented from rotating relative to each other while achieving torque transmission during the transmission process, thereby improving the working stability. At the same time, the limiting rib 312 and the limiting groove are arranged at the relative outer sides of the whole machine, so that the main machine 1 is better aligned when it is installed, which helps to improve the assembly efficiency.

[0049] Furthermore, a micro switch and a first switch connecting rod are provided in the main unit 1. One end of the first switch connecting rod cooperates with the micro switch, and the other end extends from the limit groove. The food processor has a second working state in which the motor 11 directly drives the crushing device 4 to rotate. When in the second working state, the limit rib 312 drives the first switch connecting rod and triggers the micro switch.

[0050] By matching one end of the first switch link with the micro switch and the other end extending from the limit groove, the structure of providing a notch on the bottom wall to expose the first switch link is omitted, and the structure of providing a convex rib on the bottom wall of the receiving groove 31 to drive the first switch link is omitted, so that the limit groove and the limit rib 312 can provide triggering for the micro switch while achieving the limit, thereby improving its function. It can also reduce the situation where the user is difficult to clean due to too many convex ribs in the receiving groove 31, which helps to further improve the convenience of cleaning the cup cover 3.

[0051] As a preferred embodiment under this embodiment, Figure 2 , Figure 4 As shown, the cup cover 3 also includes a through hole 32 for the top end of the crushing device 4 to extend out, and a rib 311 arranged around the through hole 32 is provided between the outer side of the through hole 32 and the limiting rib 312, and the rib 311 supports the bottom wall of the reduction box 5.

[0052] By providing a surrounding rib 311 arranged around the through hole 32 between the outer side of the through hole 32 and the limiting rib 312, the surrounding rib 311 supports the bottom wall of the reduction box 5, further enhancing the supporting and limiting effect of the accommodating groove 31 on the reduction box 5, thereby further enhancing the stability of the connection between the reduction box 5 and the main machine 1, avoiding the situation where the reduction box 5 is displaced due to unstable cooperation with the installation groove 12, resulting in unstable transmission or even jamming, and improving the stability of torque transmission.

[0053] As a preferred embodiment of this embodiment, there are multiple limiting ribs 312 and limiting grooves, and they are spaced apart along the circumference of the accommodating groove 31 and the circumference of the bottom wall, wherein the other end of the first switch connecting rod extends out from only one limiting groove, and the other limiting grooves cooperate with the limiting ribs 312 to achieve the limiting cooperation between the cup cover 3 and the host 1.

[0054] It should be noted that the present application does not specifically limit the assembly method of the reduction box 5 and the mounting groove 12. As a preferred embodiment of the present application, Figure 2 , Figure 4 As shown, one of the side wall of the reduction box 5 and the side wall of the mounting groove 12 is provided with a turn button 53, and the other of the two is provided with a turn groove 121 matched with the turn button 53. Preferably, as shown in FIG. Figure 4 As shown, the rotation groove 121 is arranged on the side wall of the mounting groove 12 , and the rotation buckle 53 is arranged on the side wall of the reduction box 5 .

[0055] By providing a turn buckle 53 on one of the side walls of the reduction box 5 and the side walls of the mounting groove 12, and providing a rotation groove 121 cooperating with the turn buckle 53 on the other of the two, the reduction box 5 and the mounting groove 12 can be connected and matched through the limiting of the turn buckle 53 and the rotation groove 121, which can not only provide circumferential anti-rotation limiting, but also provide axial limiting for the reduction box 5, further enhancing the limiting effect of the mounting groove 12 on the reduction box 5, ensuring the reliability of the position of the reduction box 5, and further ensuring the stability of the operation of the whole machine.
