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 machine body, a cup body assembly provided on the machine body and having a grinding chamber, a grinding device provided in the grinding chamber, and a motor assembly provided below the cup body assembly and transmission-connected to the grinding device. When using the food processor, the user places the food in the grinding chamber, and the motor assembly drives the grinding device to rotate at high speed to process the food.

[0003] Most of the existing motors are brushed motors, but this type of motor will generate large noise and vibration when working, and the user experience is poor. In order to improve the processing effect, most manufacturers will use brushless motors to replace brushed motors. Brushless motors have many advantages such as long life, low vibration, low noise, and no carbon powder pollution. Due to the reduction in the size of the brushless motor, especially the reduction in the axial size, a larger cavity will be formed under the brushless motor compared to the brushed motor. In order to fill the cavity and also to support the brushless motor, a support seat is usually set under the brushless motor. The brushless motor is installed on the support seat. With the increase in structural components, especially the increase in axial structural components, the number of axial dimension chains is large, and the assembly precision requirements are high. However, the radial upper limit structure of the support seat is small, resulting in inaccurate radial positioning. When the motor assembly is installed on the support seat, the coaxiality of the motor assembly and the whole machine is low, which leads to unstable transmission with the crushing device and generates large noise. At the same time, the inaccurate positioning of the whole machine will lead to large assembly errors, which will easily generate vibration noise when the whole machine is working, seriously affecting the consumer experience. Utility Model Content

[0004] The utility model aims to provide a food processing machine with precise positioning, so as to solve the problem that the radial positioning of the support seat in the existing food processing machine is not precise, resulting in low coaxiality of the whole machine assembly, unstable motor transmission and easy vibration and noise generation of the whole machine.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine with precise positioning, including a machine body, a cup body assembly arranged on the machine body and having a grinding chamber, a grinding device arranged in the grinding chamber, and a motor assembly arranged below the cup body assembly and transmission connected to the grinding device.

[0006] The present application provides a positioning hole on the support seat, and the positioning hole cooperates with the mounting portion and / or the connecting portion in a limiting manner. On the one hand, while the base and the casing are connected and fixed, the support seat can also achieve its radial positioning by means of the limiting cooperation between the positioning hole and the mounting portion and / or the connecting portion, thereby achieving a limiting effect on the support seat and ensuring the stability of its position, effectively avoiding the position deviation of the support seat due to vibration during the long-term operation of the food processing machine, causing the displacement of the motor assembly above the support seat, and ultimately causing the motor transmission to be unstable or even unable to work, thereby ensuring the stability of the operation of the entire machine; on the other hand, when assembling the entire food processing machine, you can first The support base and the pedestal are pre-positioned, and with the help of the positioning hole and the positioning cooperation of the mounting part, the support base and the pedestal are accurately aligned. Then, when the casing and the pedestal are connected and fixed, the cooperation accuracy of the casing, the pedestal and the support base can be improved, thereby making the positioning and cooperation of the whole machine more accurate. In particular, the coaxiality of the motor assembly on the support base and the whole machine can be improved, thereby further improving the stability of its transmission, avoiding the situation where the coaxiality between the motor assembly and the whole machine is low, resulting in unstable transmission and generating large noise, and at the same time avoiding the situation where the inaccurate positioning and cooperation of the whole machine leads to large assembly errors, which makes it easy for the whole machine to generate vibration and noise when it is working, thereby improving the user experience.

At the same time, the vertical height of the via hole can be raised to avoid the situation where water stains on the desktop enter the body through the gap between the via hole and the connector, causing the internal electrical components to be damp and short-circuited or even damaged, thereby improving the protection of the electrical components in the body. In addition, the support seat is provided with positioning ribs arranged around the outside of the first boss, so that the support seat and the base are positioned by the cooperation of the positioning ribs and the first boss, thereby achieving the positioning and cooperation of the casing, the base and the support seat, which helps to further improve the accuracy of the positioning of the whole machine.

[0013] In a preferred implementation of a food processing machine with precise positioning, the support seat is further provided with an annular rib extending upward and surrounding the outer side of the stud.

At the same time, the bottom wall of the base is provided with a rib surrounding the outside of the third boss, so that when the support seat is aligned with the base, the positioning of the rib and the third boss can be used to achieve rapid alignment of the two, which helps to improve assembly efficiency and further improve the accuracy of positioning of the support seat and the base.
