In order to ensure the normal operation of the food processor, a corresponding heat dissipation mechanism is required so as to maintain a proper temperature inside the main machine. In the prior art, people usually set a heat dissipation fan at the lower end of the motor, and set an air inlet and an air outlet at the bottom of the host.

As shown in fig. 1 and 2, a food processor with good heat dissipation comprises a main machine 1 with a motor 11 inside and functional components arranged on the main machine, wherein the motor comprises a heat dissipation end 111 with a centrifugal heat dissipation fan 4 arranged at the lower part, an air inlet 12 and an air outlet 13 are arranged on the bottom wall of the main machine side by side, and the air outlet is positioned below the heat dissipation fan. When the food processor works, the heat generated by the operation of the motor makes the air in the main machine become hot, at the moment, the cooling fan is driven by the motor to rotate at a high speed, so that the hot air in the main machine is blown out of the air outlet hole in the bottom wall of the main machine, negative pressure is formed inside the main machine at the moment, and the external cold air can enter the main machine through the air inlet hole to form air circulation flow, so that the heat dissipation of the main machine and the motor is realized.

That is, the exhausted hot air can be completely diffused into the air, and only the external cold air enters the main unit through the air inlet hole to participate in the heat dissipation.

Preferably, the partition structure includes partition ribs 14 formed on the outer bottom wall of the main body, the partition ribs being located between the air inlet holes and the air outlet holes, thereby forming a partition-like effect between the air inlet holes and the air outlet holes. The hot air that blows off from the exhaust vent can radially scatter after receiving blocking of placing the face, and at this moment, partial hot air can scatter towards fresh air inlet one side and flow, and this partial hot air can receive blocking of isolation muscle piece and can't enter into in the intake to make cold, hot-air keep apart effectively, promote the radiating effect effectively.

Particularly, the adjacent side of the air inlet hole and the air outlet hole is surrounded by the isolating rib sheet, and the other three directions are completely opened, so that the effective diffusion of hot air and the quick entering of cold air into the main machine through the air inlet hole can be ensured, and the air circulation volume and the heat dissipation effect of the food processor are further ensured.

Preferably, the horizontal projection of the air outlet towards one side of the air inlet is positioned in the isolating rib, that is, hot air which is emitted from the air outlet and flows linearly towards one side of the air inlet can be effectively blocked by the isolating rib, only a small part of hot air can bypass the isolating rib to reach the air inlet and enter the host, and meanwhile, the size of a lateral opening formed between the air outlet and the air inlet and a placing surface can be increased as much as possible, so that the rapid emission of the hot air and the resistance of cold air entering the host through the air inlet are facilitated.

As another preferred scheme, a downward convex heat dissipation boss 15 can be arranged on the bottom wall of the outer side of the host, the heat dissipation fan is located in the heat dissipation boss, and the air outlet is arranged on the side face of the heat dissipation boss. The hot air blown by the heat radiation fan can be radially dispersed through the air outlet hole, and the heat radiation efficiency is improved. In addition, as shown in fig. 3, the isolating rib is in the shape of an arc concentric with the heat dissipating boss, so that hot air flowing towards one side of the air inlet hole is reflected towards the air outlet hole when being blocked by the concave arc-shaped isolating rib, thereby effectively preventing the hot air from entering the air inlet hole again after passing over the edges of the two sides of the isolating rib, and further improving the isolating effect of the hot air and the cold air.

Preferably, we can control the central angle α corresponding to the spacer rib in the following range: alpha is more than or equal to 90 degrees and less than or equal to 150 degrees, so that hot air blown out from the air outlet is effectively prevented from entering the host machine through the air inlet, the sizes of the lateral openings of the air outlet and the air inlet are increased as much as possible, the obstruction of hot air dispersion and cold air entering the host machine through the air inlet is reduced, and the heat dissipation effect is further improved.

Furthermore, a heat dissipation groove 16 can be formed in the bottom wall of the outer side of the host, and the heat dissipation boss is arranged at the bottom of the heat dissipation groove, so that the lower surface of the heat dissipation boss can be kept flush with the bottom wall of the host, gaps between the bottom wall of the host and a placing plane can be fully utilized, on the other hand, the side wall of the heat dissipation groove forms an effect similar to an air guide cylinder, hot air is guaranteed to be blown out from the opening of the heat dissipation groove in a downward concentrated mode, and then the isolation rib pieces are convenient to prevent hot air from flowing to one side of.

Furthermore, as shown in fig. 4, the heat dissipation groove extends transversely away from the side of the air inlet and penetrates through the side wall of the main machine, so as to form an air outlet channel 17, and at this time, the hot air blown out from the air outlet can be rapidly discharged out of the main machine through the transverse air outlet channel. It can be understood that the gap between the air outlet channel and the placing surface is far larger than the gap between the bottom wall of the main machine and the placing surface, so that the flow resistance of hot air is favorably reduced. That is, when the hot air is discharged from the air outlet, the hot air resistance in the air outlet channel is much smaller than the hot air flowing resistance towards the air inlet, so that the hot air is preferentially discharged through the air outlet channel, and the discharged hot air is far away from the air inlet on the premise of effectively increasing the hot air flowing speed.

In order to facilitate the cold air to enter the air inlet fast, an annular air guiding rib sheet 18 for micro-washing the air inlet can be arranged on the bottom wall of the outer side of the main machine, that is, the air inlet is positioned in the air guiding rib sheet. The wind-guiding rib piece can effectively isolate the air inlet hole and the air outlet hole on one hand, is favorable for increasing the opening size of the air inlet hole on the other hand, and has the functions of gathering and guiding cold air entering the air inlet hole.

In addition, the inner side wall of the air guiding rib sheet can be made into a conical surface with a large opening and a small opening, so that an air guiding channel formed by the air guiding rib sheet is in a conical shape with a large opening and a small opening. After cold air enters the air guide rib pieces, the cross section of the cold air is gradually reduced, and correspondingly, the speed of air flow is gradually increased, so that the heat dissipation effect of the motor in the host machine is favorably improved.

It can be understood that when the outside cold air enters the host machine through the air inlet hole, the cold air can directly turn to and is discharged outside through the air outlet under the negative pressure adsorption action of the air outlet hole, so that the flow path of the cold air in the host machine is shortened, and the heat dissipation effect on a motor and the like in the host machine is influenced.

Therefore, the bottom wall of the inner side of the host can be provided with the flow guide rib pieces 19 positioned between the air inlet holes and the air outlet holes, and the height of the flow guide rib pieces is larger than that of the heat dissipation fan, so that cold air entering the host through the air inlet holes can be blocked by the flow guide rib pieces, correspondingly, hot air blown out from the edge of the centrifugal heat dissipation fan can also be blocked by the flow guide rib pieces, and the cold air and the hot air are effectively prevented from being mixed in the host. At the moment, the cold air firstly passes through the flow guide rib and then passes through the motor, and is discharged outwards from the air outlet under the action of the cooling fan, so that the flow path of the cold air in the host machine is effectively prolonged. That is to say, the air guide rib piece can guide cold air to fully flow through the motor, and the cold air can fully take away the heat of motor and become hot-air, and this hot-air outwards discharges from the exhaust vent under radiator fan's effect to carry out effectual heat dissipation to the motor.
