Problems solved by technology

[0002] Food processors usually have crushing and heating functions. In order to avoid excessive air pressure in the mixing cup, an air vent is usually provided on the lid of the mixing cup to reduce the air pressure in the mixing cup. However, during the pulping process, especially in the When making soy milk, the foam generated by the boiling of the slurry tends to overflow from the exhaust port. In addition, during the pulping process, the noise generated by the pulverizer in the mixing cup when the food is crushed is easily transmitted from the exhaust port. This noise is very loud. The close-range test has more than 100 decibels, which affects the experience of consumers and neighbors. In the field of food processing machines, the noise problem has always been a pain point for products. Therefore, how to achieve noise reduction in food processing machines is a technology in this field. Problems that people need to solve
Although this type of solution can reduce noise when the pressure is not released, the conditions for pressure relief are difficult to control. Usually, when the pressure relief condition is reached, the air pressure inside the mixing cup is already very high, and the air flow is easy to carry foam. Or the slurry rushes out of the exhaust channel to cause overflow, and the rapid rushing out of the airflow causes a lot of noise. This type of structure can only play a role in reducing noise when the pressure relief condition is not met.
In addition, due to the complex pressure relief structure, there are many dead spots for cleaning, and it is difficult to clean the noise reduction cover

Embodiment 1

[0043] like Figures 1 to 5 As shown, the present invention provides a food processor with good noise reduction effect, which includes a main machine 1 and a stirring cup 2. The main machine 1 is provided with a motor and a control board, and the stirring cup 2 is provided with a pulverizer 3, and the motor drives the pulverizer 3. Rotate, the stirring cup 2 includes a cup body 21 and a cup cover 22 that covers the top of the cup body 21. The stirring cup 2 also includes a cup holder 23. A cutterhead 4 is arranged between them, and a heat pipe 41 is arranged on the outside of the cutterhead 4. The heat pipe 41 is fixed on the outside of the cutterhead 4 by brazing, and the crushing knife 3 is rotated on the bottom wall of the cutterhead 4. The body 21 and the cutter head 4 encircle to form a crushing chamber 24, the cup cover 22 is provided with an opening, the opening extends downwards to form a feeding channel 221, the feeding channel 221 is provided with a noise reduction c...

Embodiment 2

[0062] The difference between this embodiment and the first embodiment lies in that the positions of the air intake holes are different.

[0063] In this example, if Image 6 As shown, the insertion portion 53 includes a bottom wall and a side wall, and the air inlet 531 is located near the junction of the bottom wall and the side wall of the insertion portion 53, so that the air flow is difficult to form air bubbles at the air inlet, and the contact between the air bubbles and the inner cavity Because of multi-surface contact, the direction of surface tension of the bubbles is different, so it is difficult to form bubbles, that is, it is easier to break the bubbles, and at the same time, the exhaust is smoother, and the air pressure difference between the inner cavity and the crushing cavity is better maintained, which is conducive to breaking the bubbles. Air holes can also be arranged on the bottom wall of the insertion part, especially at the center, so as to maintain the ...

Embodiment 3

[0066] The difference between this embodiment and Embodiments 1 and 2 is that the inner surface of the top cover of the noise reduction cover is provided with a diffuse reflection surface.

[0067] In this example, if Figure 7 As shown, the inner surface of the noise reduction cover top cover 56 is provided with a diffuse reflection surface 561, and the diffuse reflection surface 561 is provided with multiple circles and rings are set in phase, that is, the combination of multiple circles of concentric circles forms a sound diffuse reflection surface, so that the sound propagates to On the diffuse reflection surface, the sound waves reflected by different circles will interfere with each other to eliminate noise, so as to play a good role in noise reduction, thereby greatly reducing the noise of the food processor when it is working.

[0068] The structures and beneficial effects of other parts not described are the same as those of Embodiments 1 and 2, and will not be repeat...

Abstract

The invention relates to a food processor with a good noise reduction effect. The food processor comprises a main machine, a motor and a stirring cup, a smashing cutter driven by the motor is arranged in the stirring cup, the stirring cup comprises a cup body and a cup cover covering the cup body, a smashing cavity is defined by the cup cover and the cup body, an opening is formed in the cup cover, and a noise reduction cover with a hollow inner cavity is arranged at the opening. The noise reduction cover and the opening are sealed, the noise reduction cover is provided with an air inlet hole communicating the inner cavity with the crushing cavity and an air outlet hole communicating the inner cavity with the outside, the equivalent inner diameter of the air inlet hole is D1, the equivalent inner diameter of the inner cavity is D2, 0.03 < / = D1 / D2 < / = 0.2, the hollow inner cavity does not block an airflow, and the airflow rapidly enters the inner cavity and is discharged from the air outlet hole so that the air pressure in the stirring cup is rapidly released; and an overflow prevention effect is achieved, by controlling the equivalent inner diameters of the air inlet hole and the inner cavity, sound energy in the airflow enters the inner cavity and then is quickly released, the amplitude of sound waves is reduced, and the sound intensity is reduced so that the noise reduction effect is achieved.
