Example one

As shown in fig. 1 to 6, the utility model provides a reduce food preparation machine of host computer noise, including host computer subassembly 2 and cup body assembly 1, host computer subassembly 2 includes base 25 and locates main part 21 on the base 25, be equipped with motor 22 in the main part 21, motor 22 has motor cover 221, cup body assembly 1 includes the cup, the lock in the bowl cover of cup and locate the crushing cutter subassembly in the cup, and motor 22 drive crushing cutter subassembly rotates.

In order to reduce the noise of the main unit, a separation cover is provided between the motor cover 221 and the main body 21. Through the arrangement of the separation cover, an outer cavity is formed between the separation cover and the main body, and an intermediate cavity is formed between the separation cover and the motor cover. The top of the motor cover is provided with an air inlet 221-1 communicated with the inner cavity of the motor cover, the base 25 is provided with an air suction opening 251, an air inlet channel communicated with the air suction opening 251 and the air inlet 221-1 is formed in the middle cavity, and the bottom of the separation cover is provided with an air inlet communicated with the air suction opening.

Wherein, the noise of the motor is reduced by multiple sound insulation. As shown in fig. 5, three cavities, namely an inner cavity of the motor cover 221, a middle cavity formed by the motor cover 221 and the main body inner cover 211, and an outer cavity formed by the main body inner cover 211 and the main body outer shell 212, are used for reducing noise of the motor per se in three layers step by step.

It can be understood that the radial width and the axial height of the inner cavity, the middle cavity and the outer cavity of the motor cover can be sequentially increased from small to large, so that the interior of the attenuation space of sound is divided into three gradients, and the three gradients are absorbed layer by layer from inside to outside. Of course, the radial width and the axial height of the inner cavity, the middle cavity and the outer cavity of the motor cover are not particularly limited.

The noise brought by the wind circulation heat dissipation system adopts a wind circulation channel to reduce wind noise. As shown in fig. 5, the wind is sucked from the wind suction openings 251 on both sides of the base 25, and after entering, due to the obstruction of the main body inner cover 211, the wind is forced to enter the motor through the middle cavity formed between the motor cover 221 and the main body inner cover 211 through the wind inlet on the top of the motor cover, and finally blown out from the wind outlet, thereby reducing the wind noise.

Because the noise is reduced from the aspects of motor sound and wind sound, the noise reduction effect is obvious, and the noise can be reduced by 3dB.

In the embodiment, the designed noise reduction structure is only provided with the separating cover on the basis of the existing main body structure, so that the noise reduction structure is simple and has obvious effect under the condition of not influencing production assembly and cost.

Therefore, the path of the wind is extended through the volute, so that the noise after the wind is exhausted can be further attenuated.

As shown in fig. 5 and 6, after the assembly of the main unit assembly 2 is completed, the main body inner cover 211 and the motor cover 221 divide the inside of the main body 21 into three cavities, that is: when the main machine starts to work, the noise generated in the main body 21 is divided into the noise of the motor and the noise caused by the wind circulation heat dissipation system. The host noise reduction system comprises: the three cavities of the inner cavity of the motor cover 221, the middle cavity formed by the motor cover 221 and the main body inner cover 211 and the outer cavity formed by the main body inner cover 211 and the main body outer shell 212 are used for reducing the noise of the motor by three layers step by step.

As shown in fig. 3 and 4, a clamping groove 242 may be further disposed on the upper side of the scroll casing 241, a clamping rib 211-1 is disposed at the bottom of the inner cover of the main body, the clamping rib 211-1 is engaged with the clamping groove 242, the clamping rib 211-1 is in clearance fit with the clamping groove 242, and two ends of the clamping groove 242 are through, so that wind may pass through the clamping groove. The clamping rib 211-1 and the clamping groove 242 are matched to prevent wind from being discharged out of time at the top of the volute 241, and the wind is prevented from remaining in the main body 21 to generate squeaking sound.

In addition, when wind remains in the main body 21 and cannot be discharged in time, the main body inner cover 211 attenuates wind noise to prevent the wind noise from being directly transmitted to the outside of the main body 21.

The motor 22 may be fixed to the top wall of the main body housing 212 using screws. A circuit board 23 is mounted on the radially outer side of the motor.
