Abstract
The utility model discloses a wind shield ring structure inside a volute of a European style range hood. According to the structure, a wind shield ring is fixedly arranged on the inner side surface of a side plate at an air inlet of the volute; the inner diameter of the wind shield ring is slightly greater than the outer diameter of an impeller; a free end of the wind shield ring is aligned to the side end face of the impeller close to the free end to prevent air from flowing across a mounting gap formed by the inner side surface of the side plate at the air inlet of the volute and the side end face of the impeller close to the volute; when the air flow enters from the air inlet of the volute and does not flow across the mounting gap but is directly discharged from an outlet of the volute by the rotation of the impeller, the flowing guide of wind in the volute is benefited, thus the air flow convolution generated due to the presence of the mounting gap and the disturbance on the normal air flow are avoided, unnecessary noises are avoided; and as the wind shield ring is arranged at the air inlet of the volute, wind is directly discharged by the impeller after being gathered at the air inlet, and therefore, the loss of air quantity is avoided.
Description
Technical field
The utility model relates to a kind of range hood wind loop structure, relates in particular to the inner wind loop structure of a kind of European type cooker hood volute.
Background technique
At present the blower fan group of European type cooker hood generally comprises fan scroll in air outlet tube, centrifugal blower chamber, is located at the interior impeller of volute and drives the motor of this wheel rotation.Assembling due to impeller on volute need to have certain mounting point surplus, therefore at intake grill place's side plate inner side surface of volute and near the assemblage gap that is formed with a certain size between the impeller side end face of this side volute.After entering intake grill under the impeller drive that air-flow is rotating, easily at assemblage gap punishment stream, this fraction air-flow that distributes easily disturbs the principal direction air-flow to this air-flow, easily forms eddy current or turbulent flow, produces unnecessary noise; Due to the existence of assemblage gap, make the loss of main air amount obviously increase simultaneously, reduced the working efficiency of range hood.Therefore the structural design that is used for improving the guiding of blower fan group system wind flow and reducing wind loss becomes one of current range hood urgent problem.
The model utility content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of European type cooker hood volute inner wind loop structure, and it can overcome existing range hood volute internal gas flow phase mutual interference, wind loss and the unnecessary noise problem that therefore produces.
The utility model in order to solve the problems of the technologies described above the technological scheme that adopts is:
The inner wind loop structure of a kind of European type cooker hood volute, comprise the volute that is arranged on range hood and be installed on the interior impeller of described volute, form assemblage gap between intake grill place's side plate inner side surface of described volute and the close impeller side end face of this side volute, be installed with wind loop on the intake grill place side plate inner side surface of volute, described wind loop just can block the described assemblage gap of airflow passes.
Its further technological scheme is:
The structure that described wind loop just can block the described assemblage gap of airflow passes is: a wind loop axial side is fixedly connected with the side plate inner side surface at described volute intake grill place, the axial another side of wind loop forms free end, the internal diameter of this wind loop is slightly larger than the external diameter of described impeller, and the free end of this wind loop and close this free-ended impeller side end face.
The side plate inner side surface at the axial side of described wind loop and volute intake grill place is butt-joint formula linkage structure.
Large 4 ~ 6 millimeters than the external diameter of described impeller of the internal diameters of described wind loop.
Large 5 millimeters than the external diameter of described impeller of the internal diameters of described wind loop.
Described volute is single intake grill volute, and the quantity of described wind loop is that one and its are fixedly arranged on the side plate inner side surface at volute intake grill place.
Described volute is two intake grill volutes, and the quantity of described wind loop is that two and its are fixedly arranged on respectively on the side plate inner side surface at intake grill place, volute both sides.
Described wind loop is the round as a ball structure of sheet metal part.
useful technique effect of the present utility model is: this structure is installed with wind loop on the intake grill place of volute side plate inner side surface, the internal diameter of this wind loop is slightly larger than the external diameter of impeller, its free end and close this free-ended impeller side end face, just can block airflow passes volute intake grill place's side plate inner side surface and form assemblage gap near between the impeller side end face of this side volute, when air-flow from the assemblage gap of not flowing through after the intake grill of volute is come in, and directly discharged from the exhaust outlet of volute by the rotation of impeller, the guiding that is conducive to wind flow in volute, therefore avoided air-flow convolution that the existence due to assemblage gap produces and to the disturbance of normal airflow, thereby avoided unnecessary noise, and because the intake grill place of volute is equipped with this type of wind loop, therefore wind is gathered after intake grill and directly discharged by impeller, avoided the loss of air quantity.

Embodiment
In conjunction with Fig. 1 to Fig. 4, the utility model is described in further detail.
The inner wind loop structure of a kind of European type cooker hood volute, comprise the volute 1 that is arranged on range hood and be installed on the interior impeller 2 of described volute 1, form assemblage gap between intake grill 3 place's side plate inner side surfaces of described volute 1 and the close impeller side end face 5 of this side volute, be installed with wind loop 4 on intake grill 3 place's side plate inner side surfaces of volute 1, described wind loop 4 just can block the described assemblage gap of airflow passes.
the structure that described wind loop 4 just can block the described assemblage gap of airflow passes is: wind loop 4 an axial side is fixedly connected with the side plate inner side surface at described volute intake grill 3 places, the axial another side of wind loop 4 forms free end, the internal diameter of this wind loop 4 is slightly larger than the external diameter of described impeller 2, and the free end of this wind loop 4 flushes with close this free-ended impeller side end face 5, after air-flow is come in from the intake grill 3 of volute 1, the assemblage gap of not flowing through under the effect of wind loop 4, and directly discharged from the exhaust outlet of volute 1 by the rotation of impeller 2, therefore avoided air-flow convolution that the existence due to assemblage gap produces and to the disturbance of normal airflow, and because intake grill 3 places of volute 1 are equipped with this type of wind loop 4, therefore wind is gathered at intake grill 3 rear directly by impeller 2 discharges, avoided the loss of air quantity.
