Abstract
The utility model relates to an air-out device of a range hood, which comprises a shell body and a motor, wherein the shell body is provided with an air inlet and an air outlet, and the motor is arranged in the shell body. The shell body comprises a volute provided with a spiral smoke guide channel and a diffuser connected with an outlet of the volute. A conical surface which is shrunk from the opposite interior sides to the external diameter is arranged at each end of the diffuser. The air inlet is formed at an inlet of the volute, and an air guide piece is arranged in the volute, wherein the air guide piece faces to the air inlet, and the external diameter of the air guide piece is less than the external diameter of the air inlet. The air-out device of the range hood has the beneficial effects that due to the utilization of the volute, the diffuser and the air guide piece, noise caused by the turbulence inside the volute is effectively reduced; the diffuser gathers air flow in a cavity and then exhausts the air flow through the small-bore air outlet to further improve the air-out effect and the noise-reduction effect; the shape of the air guide piece is rationally designed and conforms to the fluid mechanics principle so that the noise caused by the turbulence is further reduced; and an air guide circle improves the air-in effect and edges the periphery of the air inlet to achieve the protection function.
Description
Technical field
The utility model relates to the machine for kitchen use technical field, is specifically related to a kind of range hood and goes out wind apparatus.
Background technology
Range hood has become one of kitchen imperative equipment at present; Existing range hood goes out wind apparatus and generally comprises one and have the housing of air inlet and air outlet and be located at the motor in the housing, and motor adopts the centrifugal fan air-out more, and its relative suction is big; Noise ratio is lower and receive an acclaim; In any case but noise still exists, noise is generally from two aspects, the one, impeller noise; The 2nd, the turbulence noise that air-flow moves and sends in leading cigarette channel, providing a kind of range hood of excellent noise reduction effect to go out wind apparatus becomes problem demanding prompt solution.
Summary of the invention
To the problems referred to above that prior art exists, the utility model provides a kind of range hood of excellent noise reduction effect to go out wind apparatus.
The technical scheme that realizes the utility model purpose is:
A kind of range hood goes out wind apparatus; Comprise that one has the housing of air inlet and air outlet and is located at the motor in the housing; Said housing comprises having the spiral case and the diffuser that is connected in the spiral case exit that spiral is led cigarette channel, and diffuser two ends inwall all has the conical surface that outwards directly contracts to the inside by mutually; The volute inlet place forms air inlet, also is equipped with one in the spiral case towards air inlet and the external diameter conducting element less than air inlet.
Further, the inlet air flow conical surface subtended angle of said diffuser and spiral case link is more than or equal to the flow cone face of the giving vent to anger subtended angle as air outlet one end.
Further, the inlet air flow conical surface subtended angle of said diffuser is 90～180 °, and the flow cone face subtended angle of giving vent to anger is 0～90 °.
Preferably, said conducting element has the conical surface that contracts to external diameter, and the conducting element tail end is fixedly connected with motor shaft.
As another preferred version, said conducting element has the conical surface that contracts to external diameter, and the spiral case inwall has at least two connectors that in the spiral case cavity, extend, and the conducting element tail end is fixedly connected with connector, and the gap between the connector forms air-inlet grille.
Further, said conducting element is a rotary body, and bus is the camber line that outwards swells.
Further, air inlet is stretched out in said conducting element end.
Further, said spiral case air inlet also is provided with air-ducting ring, and air-ducting ring has the wind-guiding conical surface that ecto-entad directly contracts.
Further, said air-ducting ring has the lip limit of stretching out air inlet, and the lip limit is fixedly connected with the spiral case outer wall.
Further, said spiral case has the lip of connection limit respectively with diffuser, and two connect the lip limit fixes through bolt or welding.
The beneficial effect of the utility model mainly shows: spiral case, diffuser and conducting element are set, effectively reduce the noise that turbulent flow causes in the housing; Diffuser is discharged airflow concentration in cavity volume again through small-bore air outlet, further improve air-out and noise reduction; The shape of conducting element is provided with rationally, meets fluid mechanics principle, further reduces turbulence noise; Air-ducting ring improves the air intake effect and air inlet edge bound edge is provided with, and plays protective action.
