Description

A household cooking machine

technical field

The invention relates to the field of home appliances, in particular to a household cooking machine.

Background technique

At present, most families are equipped with cooking machines, which are used to grind solid fruits, vegetables or meat into fluids.

Existing cooking machines generally consist of a cup body and a base of the main unit, and the cup body is detachably mounted on the base of the main unit for stirring. And because the operation of the motor in the base of the main machine will generate vibration and noise, the vibration generated when the base of the main machine is running will be transmitted to the cup and the table on which the base of the main machine is placed, causing the noise of the cooking machine to increase during operation, thereby generating noise pollution. At present, some cooking machines realize the noise reduction of the cooking machine by covering the outside of the cooking machine with a soundproof cover, adding a soundproof shell, etc., but this kind of noise reduction method will increase the overall volume of the cooking machine, which is not convenient for users to store.

technical problem

A household cooking machine is provided, which reduces the noise during operation of the cooking machine without increasing the overall volume of the cooking machine.

technical solution

A household cooking machine, comprising a host base, said host base includes a shell, a drive mechanism, a plurality of buffer assemblies and a plurality of rubber bearings;

A plurality of the rubber brackets are evenly distributed on the bottom of the housing;

The driving mechanism is installed in the housing, and the driving mechanism is inserted on the rubber bracket through a plurality of support rods;

A plurality of buffer assemblies are arranged around the housing, and one end of the buffer assembly is horizontally inserted into the inner wall of the housing, and the other end is horizontally pressed against the side wall of the driving mechanism;

The inner wall of the housing has a plurality of first noise-reducing protrusions arranged around the inner wall of the housing and uniformly distributed for refracting the noise generated by the driving mechanism;

The housing has a vacuum interlayer.

Beneficial effect

The buffer assembly is provided to support the driving mechanism in the horizontal direction, so as to reduce the vibration generated when the driving mechanism is running, thereby reducing the noise generated when the shell resonates. A rubber support is provided to generate a buffer zone in the vertical direction between the drive mechanism and the casing, so as to reduce the vibration generated by the drive mechanism to the casing. Due to the mutual cooperation of the buffer assembly and the rubber bearing, it is possible to provide support for the driving mechanism in the horizontal and vertical directions, avoiding the contact between the driving mechanism and the shell, thereby reducing the transmission of vibration waves during the operation of the driving mechanism, and achieving shock absorption Noise reduction effect. Inside the casing, there is a first noise-reducing protrusion arranged around the inner wall of the casing, which is used to refract noise inside the casing and reduce the transmission of noise to the outside. Since part of the sound will still spread outward after being refracted inside the casing, Therefore, a vacuum interlayer is set in the shell to block the transmission of noise, so that the sound is double blocked when it propagates outward, thereby achieving the effect of noise reduction. The invention achieves the purpose of reducing the noise of the cooking machine under the joint action of the buffer assembly, the rubber support, the vacuum interlayer and the first noise reduction protrusion, and since all the structures are located inside the casing, the overall volume.
