Description

impeller

The utility model relates to an accessory applied to a blower device such as a range hood or a blower, in particular to an impeller which is assembled on a motor and is provided with a reinforcing ring frame to provide good support for each blade.

Conventional exhaust hoods or air blowers, such as blowers, usually use a motor to drive the impeller to rotate to generate a pumping air. Referring to the prior art impeller 90 structure shown in FIG. 5, the impeller 90 is provided with a hub 91 in the shape of a disk. A ring frame 92 in the shape of a circular ring frame is coupled around the hub 91 and is equidistant. In the circumferential manner, a plurality of blades 93 are combined with the ring seat 92. The extending direction of each blade 93 is perpendicular to the ring seat 92, and a ring frame 94 is coupled to the extended end of each blade 93. The hub 91 of the impeller 90 is assembled and coupled to a drive shaft (not shown) of the motor, so that the motor 90 can be driven to rotate to generate a function of drawing or blowing air.

Each of the blades 93 of the conventional impeller 90 is connected by the ring seat 92 at both ends and the ring frame 94. The blades 93 have no other connection design between the two ends, and since each of the blades 93 has an elongated structure, When the motor drives the impeller 90 to rotate at a high speed, the blades 93 are easily deformed by the wind resistance and the centrifugal force, which not only causes the impeller 90 to generate vibration, but also affects the smoothness of the rotation, the efficiency of the pumping wind, and the generation of running noise, and is likely to cause the The impeller 90 is damaged by deformation or deformation.

In order to solve the problem that the supporting force of each blade of the existing impeller is insufficient, there is a deficiency and limitation that easily generate vibration, noise or crack, deformation, and the main purpose of the present invention is to provide a reinforcing ring frame to provide good support for each blade. The impeller is effective to solve the technical problems existing in the existing impeller.

The present invention solves the technical problem of the impeller, comprising: a hub in the form of a tray, a ring seat connected around the hub, a plurality of blades connected to the ring seat at equal intervals, and a connection between each a ring frame at the extended end of the blade and one or more reinforcing ring frames attached to the inner edge of each blade.

The impeller, wherein the impeller is a one-piece construction molded of a plastic material, and the reinforcing ring frame is integrally coupled to an inner edge of the blade.

The impeller, wherein the impeller is a combined structure formed by assembling a metal plate member, and the reinforcing ring frame is welded and coupled to the blade.

The impeller, wherein the outer edge of the reinforcing ring frame abuts against the inner edge of the blade and is welded.

The impeller, wherein the reinforcing ring frame is concavely provided with a matching insert at a position corresponding to the blade at an outer circumference, and the inner edge of the blade is embedded in a corresponding insert and welded .

The impeller, wherein the blades are recessed with a matching insert at a position corresponding to the reinforcing ring frame at an inner edge, and the outer peripheral edge of the reinforcing ring frame is embedded in a corresponding insert and Welding joints.

The impeller is provided with five to ten reinforcing ring frames at equal intervals.

The impeller of the present invention provides good support effect for each blade by more than one reinforcing ring frame, and can greatly reduce the problem of cracking or deformation of each blade due to high-speed rotation, and improve the durability of the impeller.

The first preferred embodiment of the present invention is shown in FIG. 1. The impeller 10 is an integral structure molded from a plastic material. The impeller 10 includes a hub 11 in the form of a tray, and a hub 11 coupled thereto. a ring seat 12 surrounded by a circular ring frame, a plurality of blades 13 connected to the ring seat 12 at equal intervals, a ring frame 14 connected to the extended end of each blade 13, and one or more connected to It is preferable to reinforce the ring frame 15 at the inner edge of each blade 13 and to provide five to ten reinforcing ring frames 15 at equal intervals. In the first preferred embodiment as shown in the figure, the present invention is provided with eight reinforcing ring frames 15 integrally connected to the inner edges of the respective blades 13 at equal intervals, and the connecting support design of each reinforcing ring frame 15 is used for each The blade 13 obtains a good support strengthening effect, so that when the impeller 10 rotates at a high speed, the blades 13 are not deformed by the wind resistance and the centrifugal force, thereby effectively improving the smoothness of the rotation of the impeller 10, reducing the running noise and durability.

The second preferred embodiment of the present invention is as shown in FIG. 2. The impeller 10A is a combined structure formed by assembling a metal plate member. The impeller 10A includes a hub 11 having a disk shape, and a hub 11 is disposed on the hub 11. The surrounding ring-shaped ring seat 12, the plurality of blades are connected to the blade 13 of the ring seat 12 at equal intervals, a ring frame 14 connected to the extended end of each blade 13, and one or more connected to each blade 13 The reinforcing ring frame 15 of the inner edge. In the second preferred embodiment as shown, the present invention is provided with eight reinforcing ring frames 15 at equal intervals, and the outer circumference of each reinforcing ring frame 15 abuts against the inner edge of each blade 13 and is joined by welding or the like. The means are coupled to each of the reinforcing ring frames 15 to provide support strengthening for each of the blades 13.

As shown in FIG. 3, the third preferred embodiment of the present invention is substantially the same as the overall structure of the second preferred embodiment. The main difference lies in the combined structure of the reinforcing ring frame 15 and the blades 13. In the present embodiment, each of the reinforcing ring frames 15 is recessed with a fitting 151 at a position corresponding to each of the blades 13 on the outer circumference, and the shape of each of the fittings 151 matches the inner edge of the corresponding blade 13 so that each The inner edges of the blades 13 are inserted into the corresponding fittings 151 and joined by a joining means such as welding, thereby further reinforcing the joint supporting action of the reinforcing ring frames 15 for the respective blades 13.

4 is a fourth preferred embodiment of the present invention. The impeller 10C is substantially identical to the overall structure of the second preferred embodiment.
