Description

Food processor Technical Field The invention relates to the technical field of food processing devices, in particular to a food processor. Background The existing food processor, such as a wall breaking machine or a soybean milk machine, generally comprises a main machine and a crushing cup arranged on the main machine, wherein a crushing cutter is arranged in the crushing cup, a motor is arranged in the main machine to drive the crushing cutter to rotate to crush food materials, a cooling fan is arranged at the tail of the motor generally, and the cooling fan rotates to enable air flow to be discharged from an exhaust channel of the main machine through the motor, so that heat of the motor is taken away, and a motor cooling effect is achieved. For example, chinese patent with publication number CN210961675U discloses a food processor with good heat dissipation effect, which comprises a machine base with a built-in motor and a stirring cup arranged on the machine base, the stirring cup comprises a cup body, a cup cover and a crushing knife driven by the motor, a cooling fan is arranged at the bottom of the motor, the cooling fan is a centrifugal fan, the machine base comprises a main body, a base arranged at the bottom of the main body and a control board arranged in the main body, an air inlet hole, an air outlet hole and an air exhaust channel are arranged on the base, the air exhaust channel is in a volute shape and the cooling fan is arranged at the center of the air exhaust channel, the control board is arranged above the air inlet hole, when the cooling fan rotates, external air enters the machine base from the air inlet hole and is discharged from the air outlet hole after passing through the air exhaust channel, the cooling fan effectively dissipates heat to electric elements in the machine base, and the heat dissipation effect is ideal. But radiator fan locates the center department of passageway of airing exhaust, is equivalent to the passageway of airing exhaust itself and defines the fan accommodation chamber rather than coaxial arrangement, radiator fan basically directly leads to with the external world, therefore, the noise that radiator fan rotatory in-process produced can directly transmit to the passageway of airing exhaust, noise directly passes to the external world, the noise is great, and current passageway route of airing exhaust is shorter, the wind pressure that the fan blade produced is great, the air outlet of host computer can have the wind pressure squeal of high frequency, noise reduction effect is not ideal. There are some food processors, which can set up a baffle rib in the exhaust channel or at the air outlet to reduce noise, but the design can affect the circulation efficiency of the heat dissipation air flow, and has a certain influence on the heat dissipation effect of the motor. In some cooking appliances, for example, chinese patent publication No. CN215016378U discloses a cooking appliance, which includes a fan assembly and a heating assembly disposed above the fan assembly, the fan assembly includes a volute body including a bottom plate and a shroud disposed on a front side of the bottom plate, and a fan disposed in the volute body, the shroud has a spiral cross section, and the fan and the volute body are eccentrically disposed. In this scheme, the fan blows in the spiral case body, and spiral case body is with wind direction heating element, blows the heating element after the heating to cooking utensil inside the heating of food realization. The cross section of bounding wall is the spiral line, can guarantee that the air-out is even for the air can get into heating element evenly under the direction effect of fan and bounding wall. The fan and the volute body are eccentrically arranged. Like this make the wind channel between bounding wall and the fan that is close to first end one side narrow, the air receives the extrusion, and the wind pressure increases for the wind that blows out from the fan subassembly has great kinetic energy, solves the problem of the local high temperature of heater, can't solve the big problem of fan noise. Therefore, in the existing food processor, especially the food processor with the crushing function, the problem of large heat dissipation noise exists on the premise of ensuring the good heat dissipation effect of the motor. Disclosure of Invention The invention aims to provide a food processor which is used for solving the problem that the existing food processor has larger heat dissipation noise on the premise of ensuring good heat dissipation of a motor. In order to achieve the above purpose, the invention provides a food processor, comprising a machine body and a crushing cup arranged on the machine body, wherein the crushing cup is provided with a crushing device, the machine body comprises a machine shell, a motor arranged in the machine shell, a cooling fan arranged at the bottom end of the motor and an exhaust assembly, th
