Description

Food processor

Technical Field

The invention relates to a kitchen appliance, in particular to a food processor with a stirring function.

Background

Existing food processors typically have a blending function, which mainly comprises: a body having a rotation driving function; a cup body mounted on the body; and a stirring cutter installed in the cup body and rotationally driven by the machine body. The stirring blade is usually rotated by a driving motor in the machine body.

For example, CN103565301A discloses an electric food processor. The electric food processor comprises a pot body, a handle, a pot body cover, a base fixed at the bottom of the pot body, a machine body, a driving motor positioned in the machine body and a stirring knife group positioned in the pot body. The stirring knife group is directly driven to rotate by the driving motor. Due to the large rotation speed of the driving motor, there may be a case where the torque is insufficient when the amount of food to be stirred is large. Therefore, it is often necessary to reduce the rotational speed and increase the drive torque by means of a transmission.

CN109758006A discloses a food processor. The food processor comprises a cup body, a cup cover rotatably buckled on the cup body, a handle, a machine body, a driving motor positioned in the machine body, a belt wheel transmission mechanism and a stirring knife group positioned in the cup body. The belt wheel transmission mechanism comprises a small belt wheel, a belt, a large belt wheel and a transmission wheel. The small belt wheel drives the large belt wheel to rotate through the belt, so that the rotating speed of the driving motor is reduced to a certain extent, and the torsion is increased. However, the individual pulley transmission is prone to problems of uneven rotation speed due to belt slip, and may also lead to insufficient torque due to belt slip.

It is therefore desirable to provide a food processor that overcomes the above disadvantages.

According to a preferred embodiment of the present invention, the pulley transmission mechanism includes a small pulley, a belt, and a large pulley, and the small pulley rotates the large pulley through the belt to reduce the rotation speed of the motor and increase the torque force.

According to a preferred embodiment of the invention, the planetary gear comprises a sun wheel, planet wheels, a planet wheel holder and an external gear box, the sun wheel drives the planet wheels to rotate, thereby further reducing the rotation speed and further increasing the torque force.

According to a preferred embodiment of the present invention, the cup assembly includes a cup cover, a cup body, and a cup base, the planetary gear drive being located within the cup base.

Detailed Description

The present invention will be described in more detail with reference to specific examples. It is to be understood by those skilled in the art that these descriptions are merely illustrative of some specific embodiments of the present invention and do not limit the present invention and its scope.

In addition, spatially relative terms, such as "lower," "upper," "top," "bottom," and the like, may be used herein for ease of describing one component or its relationship to another component or components illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "lower" relative to other elements or elements could then be oriented "upper" relative to the other elements or elements. Moreover, terms such as "first," "second," and the like are not intended to emphasize order or importance of the referenced components.

Referring initially to FIG. 1, a perspective view of a food processor is shown according to one embodiment of the present invention. The food processor mainly comprises a cup component 1, a machine body component 2, a screen component 3 and a machine base 4. The cup assembly 1 may be placed on the fuselage assembly 2. The body assembly 2 is fixed to the frame 4.

In fig. 5, a base 211 for placing the motor 201 and the pulley transmission mechanism may be fixed to the base 4. The motor 201 is first fixed to the motor bracket 206 and then fixed to the base 211 by the lower connector 204. The small pulley 208 and the large pulley 209 of the pulley transmission are located between the motor bracket 206 and the base 211. To reduce vibration, several vibration isolation pads 207 may be placed between the motor bracket 206 and the base 211, and the lower connector 204 may be placed on the lower connector pads 205. The rotation shaft of the motor 201 drives the small belt pulley 208 to rotate, the small belt pulley 208 drives the large belt pulley 209 to rotate through the belt 210, and the large belt pulley 209 drives the transmission cap 212 to rotate through the large belt pulley fixing column 203. The large pulley fixing post 203 is rotatably supported in the motor bracket 206 via the lower bearing 202. The pulley transmission mechanism functioning as the primary speed reduction mechanism reduces the rotational speed of the motor and increases the torque force.
