Description

INSTALLATION FOR WINDOW AND ENGINE ASSEMBLY

Technical area

The present invention is generally directed to motor compositions. More specifically, the invention relates to an insert composition of wind turbines and an engine having a housing that improves engine efficiency and airflow characteristics. Specifically, however, the invention relates to an insert located in a cavity formed by the end bracket of the windmill and the housing and is adapted to fit existing embodiments.

BACKGROUND OF THE INVENTION

Vacuum engines with tangential bypass are used as vacuum manipulators, packing equipment, bag filling, plate cutting and as exhaust gas removal devices, to name but a few. Such vacuum models typically include a cylindrical housing or sheath that includes an engine-driven windmill that rotates about an axis. The air is sucked into the housing through an opening in the upper axial center of the housing above the windmill. As the windmill rotates, the air moves rapidly in the peripheral direction and radially outward. The housing has an outlet opening on the side of the windmill opposite the opening. The outlet is generally a cylindrical orifice positioned tangentially to the outer radial edge of the housing so that air traveling toward the periphery along the outer radial edge exits through the exit orifice in a tangential direction. Such windmills are efficient and have a low profile, allowing them to fit in appliances that require small motor assemblies.

As with most windmill models, efficiency is an important feature. Because of the uncontrolled airflow path from where the air flows from the rotating windmill to where the air flows through the outlet, unwanted turbulence and dead areas are considered to be generated. The windmill produces significant kinetic energy in the air by directing it in a tangential direction. In order to convert kinetic energy into pressure, air must be inhibited in a controlled manner. Sudden changes in cross-section can cause eddies and turbulence, which reduce kinetic energy by converting it to heat instead of pressure. The total pressure (or vacuum) produced by the wind turbine and engine assembly is thus reduced if the air flows from the wind turbine in an uncontrolled manner. As a result, there is a need for better control of the air flow in order to increase the efficiency of the windmill. Furthermore, such improvements should apply not only to new windmill assemblies but also to models that can be fitted to pre-fabricated assemblies or the manufacturer may have a molding model already in place and does not wish to change it.

Thus, there is a need in the art for an insert that can be mounted in a vacuum motor windshield housing that includes a tangential bypass that directs airflow and improves efficiency.

Summary of the Invention

In view of the foregoing, the first aspect of the present invention is to provide a windmill insert that achieves improved efficiency.

Another aspect of the present invention is to provide a windmill assembly comprising an end bracket attached to the motor assembly, an end bracket comprising a peripheral channel interrupted by an opening, a multi-blade windmill, a housing that at least partially surrounds the windmill and defines a chamber, an insert, located in the chamber, an insert containing an oblique plane extending into the duct, the peripheral oblique plane being formed such that the cross-section of the duct is varied along the circumference.

Another aspect of the present invention is met by a composition of windmills which

3 'consists of an end bracket and an insert which is cylindrical and has a central axis, the insert having a peripheral oblique surface which is pointed worm-like with respect to the axis. The insert further comprises a housing which is coupled to the end console and defines a chamber between them, and an axis-rotating windmill which is housed within the chamber and produces an air stream that runs along the peripheral oblique surface.

The best way of carrying out the invention

In the accompanying drawings, the windmill assembly of the present invention is numbered 80 and used in conjunction with the windmill / motor assembly, which is numbered 10. Given that the 80 may be used in conjunction with many other windmill / motor assemblies, components thereof that are not directly related to the insert 80 will only be described in general terms.

composition

2, motor subassembly 11. motor subassembly 11 of

As best illustrated in Figure 1, the windmill / engine 10 of the present invention comprises a motor sub-assembly 11 and a sub-assembly of the wind turbines 12. It is to be appreciated that the motor sub-assembly 11 can be assembled except the end console of the wind turbine, which is numbered 21 and described below. in any appropriate conventional manner. In one of the modes, the motor subassembly 11 includes a housing 13 which may comprise a concentrically mounted bearing 12 into which an axle is inserted 15. The axle 15 supports the armature 16 and the commutator 17 and further carries a cooling wind tunnel 18 which is mounted at the end 15 opposite the wind subassembly 12. A cooling fan 18 produces airflow through the internal components of the engine, thereby accelerating the heat transfer. The motor subassembly further includes a plurality of magnetic coils 19 and brushes 20. As is known in the art, these engine components cooperate to cause axis 15 to rotate. As will be described, the axis 15 drives the operating components of the wind subassembly.

In the second mode, the end bracket 21 is mounted at the end of the motor subassembly 11 opposite the housing 13. The end bracket 21 may be circular, ensuring that the windmill components are joined to the end bracket 21 further separating the windmill subassembly 12 by sealing the axis 15 in such a way that that the air flow from the windmill sub-assembly is not miscible with air or other substance from the engine sub-assembly. The end bracket 21 may have a plurality of ears 22 or a notch 23 that can be attached to the accompanying apparatus and placed in a position selected by the end manufacturer. The end bracket 21 includes an outer flange 24 that defines its outer radial surface. The outer flange 24 may have a raised back 25 extending radially outward and extending peripherally around the outer flange 24. The back 25 acts as a lock to which a ring of the housing 26 is mounted. In this way, the housing 26 is mounted around the outer flange 24 so as to form airtight seal. As will be described later, the housing 26 forms, together with the end bracket 21, a first chamber 27 in which some working windmill components are housed.

The end bracket further comprises a circular-shaped inner plate 28 extending radially and facing the first chamber 27. The inner plate 28 terminates at the outer radial end, where the inner flange 29 extends perpendicularly from the inner plate 28. The inner flange 29 se extends through the inner plate 28 and forms a back 30 that can support the insert 80, as will be described below. The inner flange 29 together with the outer flange 24 forms two opposite lateral walls of the circular channel 31. The channel 31 is ring-shaped and has a U-shaped cross-section, with a lower surface 32 and lateral walls defined by flanges 24 and 29. A pair of semicircular edges 33 may passes between the lower surface 23 and the flanges 24 and 29. The inner plate 28 also includes an opening for the axis 33. The channel 31 is broken in its outer peripheral portion and extends into the opening 41 (best seen in Figure 4) formed by a tangential funnel. 42, which may be integrally cast or otherwise extending from the bracket 21. It is desirable that the funnel 42 extends beyond the outer flange 24 and terminates at a tubular portion 43 to which an exhaust pipe can be installed to discharge air through the windmill subassembly 12.

The inner flange 29 and the inner plate serve as a common wall between the windmill assembly 12 and the motor subassembly 11. Through the inner flange 29 and the inner plate 28 extends a common axis 15 functionally coupled to the aforementioned motor elements. Accordingly, the support ring 45 is mounted in the center of the inner plate 28 around the axis opening 33 so that both are adapted to bear the bearing 46 and so that the ring 45 faces the motor subassembly 11. The bearing 46 is adapted to receive and support the axis 15 which rotates in it. The support ring 45 also extends from the inner plate 28 and defines a protuberance 47 extending into the first chamber 27. A seal 48 may be clamped between the bearing 46 and the retaining ring 45 and / or the protrusion to prevent contamination of air passing through the windmill subassembly. . The seal 48 may be in any form. In fact, the seal may be made according to patent Nos. 5,482,378 and / or 6,472,786, both of which are incorporated by reference.

The end bracket of the windmill 21 is further provided with a plurality of straightening pins 50 that are peripherally spaced and extending radially inwardly from the outer flange 24 into the channel 31. Further, the inner panel 28 may be provided with a plurality of holes 51, each of which is arranged such that accepts an attachment element. In the present invention, these elements are described as threaded screws 52, although other shapes such as rivets, adhesives, pins, clips, camshafts and friction surfaces may also be used. As will be described later, the pins 50 and the holes 51 serve to position the insert 80 inside the first chamber 27.

The housing 26 is provided with an opening 60 which is concentric to the axis 15. The opening 60 is arranged so that air can enter the subassembly of the windmills 12. The housing 26 contains at least one of a plurality of windmills so that it is closer to the bearing 46 , a centrifugal rotary windmill 61. This windmill consists of a plurality of relatively radial short blades 62 mounted on a disk 63 with a central bore that allows the windmill 61 to be mounted on the axis 15. The disk 63 rotates together and rests on the first centrifugal windmill 64, having a plurality of blades 65 extending radially outward. The blades 65 are located between disk 66 and ring 99, with disk 66 having a central bore allowing the first windmill 64 to be mounted on axis 15. Ring 99 has an opening for air flow 100 extending through. If an airtight structure as described in patent no. No. 5,482,378, then disk 66 may have one or more openings spaced circularly along the axis. These openings serve to remove moisture away from the bearing so that it is sucked into the air stream and extracted through the exhaust.

In the form shown, the housing 26 includes not only the wind turbines 61 and 64, but also additional wind turbines for sucking air into the wind turbine sub-assembly 12. This multi-stage design is possible by providing a housing 26 with a separating wall 67 extending radially inwards from the radial outer wall of the housing. 26. The separation wall 67 has an opening 68 which leads to an opening for the air flow 100 of the windmill 64. In this way, the separation wall 67 divides the interior of the windmill subassembly into the first chamber 27 and the second chamber 69. The separation wall 67 supports radially extending from the opening 68 radially extending. the blades 70 of the intermediate stationary windmill 71 are secured. The second operating centrifugal windmill 72 is positioned near the opening 60 and comprises a plurality of blades 73 extending radially. The blades 73 are mounted between a disk 74 having a central bore allowing the windmill 72 to be mounted on an axis 15 and a ring 104 having an eye 106 which is concentric with respect to the opening 60 in the housing 26. Although shown in this form, multi-stage windmills, it must be borne in mind that the insert can also be used with a single-stage windmill or with any configuration that receives air axially and then releases it tangentially or vice versa.

In said form, the aforementioned windmills are spaced apart and joined to the axis 15 by a plurality of elements. The first spacer 75 extends inwardly through the opening of the axis 33 and the support ring 45 and rests on the inner course of the bearing 46. The first spacer 75 may have an L-shaped cross section to provide a larger transverse surface on which the disc 63 of the windmill 61 may rest. The second spacer 76 is mounted on axis 15 between the operating wind turbines 64 and 72 and has an hourglass shape. At the end of axis 15, a nut 77 may be mounted, which may be attached to the gasket 78, which rests against the disk 74 of the windmill 72. In this way, the internal course of the bearing 46, first spacer 75, second spacer 76, windmills 61, 64 are joined together. and 72 and gasket 78 so that they all act as one unit together with the axis 15 while being driven by the motor subassembly 11.

In this way, the air is sucked into the second chamber 69 through the opening 60 while the axis 15 rotates. During rotation of the second windmill 72, the air is drawn through the eye 106 and pushed radially outward by the blades 73. Once the air is pushed radially outward over the blades 73, the blades 70 of the stationary windmill 71 direct the air flow radially inward toward the opening 68. As can be seen in Figure 2 , the opening 68 directs the airflow to the first chamber 27 through the airflow opening 100. While rotating the windmill 64, the blades 65 push the air radially outward. Suppressed air flow. .- ....... - Radial of blades 65, has both radial and tangential components. In other words, the air particles travel radially outward and rotate simultaneously with the windmill 64. Thus air travels peripherally clockwise around the chamber 27 and channel 31 as it exits the windmill, if the windmill also rotates in that direction (as shown in the form in question). Due to the difference in pressure between the outside atmosphere and the first chamber 27, the air flows from the chamber 27 and channel 31 through the opening 41. Thus, as described above, the air is sucked into the opening 60 and out of the tubular portion 43 while rotating the axis 15. Such systems are Particularly applicable to ordinary house vacuum systems, but can be used in many other fields. While the models mentioned above work satisfactorily with many devices, there has always been a desire to improve the performance of these devices. It was found that the air flow in channel 31 leads to a decrease in efficiency as described in the background of the invention. To maximize efficiency, an insert 80 is designed to direct the air flow as it flows from the wind turbine 64. The plug 80 may already be fitted to the wind turbine / motor assembly by default or may be retrofitted due to its small size and simple shape. The insert 80 and the end bracket 21 may also be formed as a single piece and mounted on the wind and engine sub-assembly in the same manner as described for the individual components. Regardless of whether the insert 80 is in the form of a detached part or the integral part is integrated with the end bracket 21, a seal 48 or its equivalent is provided to prevent moisture from accessing the bearing 46. The insert 80 is generally cup-shaped and contains a wall 81, the disk-shaped disk is centrally located on axis 15. The wall is designed to cover and fit above the inner plate 28 when mounted. The protruding bulge 82 is raised so that the bulge 47 can be adjusted from below. The protruding protuberance 82 extends from the concentric center of the wall 81 toward the windmill 64 and contains a bore 83 that allows axis 15 to flow through it. The wall 81 further comprises a plurality of grooves 84 adapted to fit the screw 52. The threaded portion of the screw 52 extends through the wall 81 and through the hole 51 on the inner plate when the assembly is assembled. The head of the screw 52 fits into the groove 84 so that the screw does not extend beyond the surface of the wall 81. In this way, the insert 80 is fixed to the end bracket when the screws 52 are tightened.

The wall 81 ends at a circular flange 85 extending axially inward from the radial edge of the wall 81 toward the end bracket 21. The flange 85 is of a suitable size to fit around the inner flange 29. A back 86 is mounted on the outer radial surface of the circular flange 85. it is adapted to fit into channel 31 and designed to gradually vary depth. At one end, the back 86 comprises an inclined wall 87 extending radially from the flange 85 toward the outer flange 24 of the end bracket 21. The inclined wall 87 is angled relative to the lower surface 32 such that, when the inclined wall 87 surrounds the wall 81, it determines the upper end 88 and lower end 89. Or else, the inclined wall 87 is arranged helically around wall 81. The upper end 88 is located relatively away from the lower surface 32 of the channel 31 compared to the lower end 89, which is closer to the lower surface 32. In this form the lower end 89 is almost aligned with the lower surface 32. It should be borne in mind that while the present invention comprises a sloping wall 87 having a constant angle with respect to the lower surface 32, no such adjustment is necessary. Thus, the angle may vary according to the circumference in a linear or logarithmic manner.

The sloping wall 87 is further supported by a pair of legs ending in channel 31. The inner leg 90 is positioned on the inner radial edge of the sloping wall 87 and extends axially toward the lower surface 32 and channel 31. Further, the outer leg 91 is mounted on the outer radial the edge of the inclined wall 87 and extending axially toward the lower surface 32 and the channel 31. Each leg has a rounded end 92 that adjoins the rounded corners 33 of the channel 31. As can be seen from Figure 6, the height of the legs 90 and 91 varies along the circumference. Specifically, when the inclined wall 87 is closer to the lower surface 32, legs 90 and 91 are correspondingly shorter, and when the inclined wall 87 is longer than the lower surface 32, legs 90 and 91 are relatively longer.

fo

Near the upper end 88 there is an end wall 93 extending down from the inclined wall 87 towards the lower surface 32 of the channel 31. When the end wall 93 is properly aligned, it runs parallel to the funnel 42. In order to properly adjust and maintain the proper position of the insert 80, the outer legs 91 have a number of slots 94 that are adapted to slide into them the pins 50 of the end bracket 21. When the insert 80 is positioned in this way, it can be further adjusted and oriented. Finally, the insert 80 includes a nozzle 95 extending for a certain distance along the outer radial edge of the inclined wall 87 so that it starts at the upper end 88 and extends in a circular fashion. The nozzle 95 restricts the cross-section at the upper back. This helps to control the braking of the air leaving the windmill 64, thus causing more air at the bottom of the slope to flow through the hopper 42 rather than circling further around the housing.

As can be seen from Figure 5, the sloping slope 86 does not extend along the entire circumference of the channel 31. When properly positioned, this cut in the tilted slope 86 is offset by the cut in channel 31 defined by the opening 41. In other words, the final wall 93 is located near the first end 108 of the opening 41 and the lower end 89 of the inclined wall 87 is located near the second end 109. In this way, the insert 80 is mounted on the end bracket 21 and, when properly adjusted, the profile and cross-sectional area channels 31 are varied as a function of circumferential position.

When the axis 15 rotates and thus rotates the working wind 64, the air, which is pushed away from the blades 65, is more efficiently directed to the opening 41 of the end bracket 21. The effective cross-sectional area of the channel 31 gradually increases in a clockwise direction starting at the upper end when the settings are as in the present invention. The effective cross-sectional area of the channel 31 is greatest at the discontinuous portion of the insert 80 corresponding to the opening 41. In this way, by changing the cross-section, the kinetic energy of the moving air is converted more to static pressure rather than to the heat generated by turbulence due to reducing the vortex when air comes from a rotating windmill.

Against this background, the improvements to the structure described above are more than obvious. The insert 80 is designed to allow the air to travel more efficiently within the sub-assembly of the wind turbines 12. When the insert 80 is installed, the wind turbine efficiency is improved and less energy is required to provide the same air flow. The insert 80 is further configured so that it can be installed in an already existing windmill sub-assembly and can be used in single or multi-stage devices (as shown in the present invention). The invention thus described represents a significant improvement in the field of windmill assemblies.

Thus, it can be seen that the object of the invention is achieved by the composition described above. According to the patent statutes, only the best and most desirable form is shown and described in detail. It is to be understood that the invention is not limited to this description. Thus, in order to take into account the whole scope and breadth of the present invention, we must refer to the following claims. '- / zaflstapfiik:
