Food processor with good noise reduction effect

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.

Description

technical field [0001] The invention relates to the field of food processing machines, in particular to a food processing machine with good noise reduction effect. Background technique [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. ...

[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
