Double-cavity range hood with damping function

Abstract

The invention discloses a double-cavity range hood with a damping function. The double-cavity range hood comprises a shell; the fan is arranged in the shell and is connected with the shell; the damping assembly is connected between the shell and the fan and used for damping the fan; the vibration assembly comprises a first damping assembly and a second damping assembly which are oppositely arranged at the two ends of the draught fan. The second damping assembly controls the fan to reciprocate in the direction of the fan air inlet. Through the structural arrangement, the first damping assembly and the second damping assembly can greatly reduce noise generated when the range hood works, meanwhile, the detection device and the controller are further arranged, and the second damping assembly can be controlled to move according to the opening state of the exhaust fume collecting hood and the oil fume concentration detected by the detection device; the position of the fan is changed, the current use state of the range hood is better met, noise is reduced, and convenience is provided for use of a user.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a dual-chamber hood with shock absorption function. Background technique [0002] With the development of society and the improvement of living standards, various electrical appliances are widely used in the kitchens of various families, bringing great convenience to people's lives and significantly improving people's quality of life. As an indispensable electrical equipment in the kitchen, the range hood is mainly used to absorb the fumes generated during the cooking process, so as to keep the kitchen air fresh and significantly reduce the impact of the fumes on the user's health. The range hood includes a motor and a centrifugal fan connected to the motor. The motor can drive the centrifugal fan to rotate to suck the smoke oil in the external environment and send it into the flue. [0003] During the operation of the range hood, the vibration of the fan is the ma...

AI Technical Summary

Problems solved by technology

Usually the fan is supported and fixed by the casing, and the vibration generated by the fan operation is directly transmitted to the casing, resulting in noise

In addition, during the long-term use of the range hood, the internal blades of the fan will inevitably be stained with oil. The oil will increase the load on the motor, cause the wear of the motor bearing, aggravate the vibration of the fan, and generate noise.

In order to improve the effect of oil suction, high-power motors are often used, which will also increase the vibration noise

[0004] In the prior art, the installation position of the shock absorbing component will block the air inlet and affect the smoking effect of the range hood. In the prior art, the shock absorbing component is uncontrollable and cannot control the movement of the fan. If the fan faces the oil fume for a long time, it will be more Quickly make the fan stained with too much oil, increase the load on the motor, and then aggravate the vibration of the fan and generate noise
