Magnetic Spinner Device With Off Center Motor and Spaced Apart Magnets

Abstract

A magnetic spinner device using an impeller system to disperse heat and stir contents there-above is disclosed herein. A motor turning the impeller is offset from a center line extending vertically through the device. The impeller, however, is centered with fan blades pushing air downwards as heat rises from a heat source placed there-below, such as between legs which support the impeller and bowl of the device, the bowl being used to hold a flask and/or substances to be heated. In this manner, the electric parts (the motor) and spared the brunt of the heat by being off-center while the heat rises upwards. The simplification of parts leaves less points of potential failure compared to the prior art as does the movement of electric parts away from being above a heat source.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSED TECHNOLOGY

[0030] A magnetic spinner device using an impeller system to disperse heat and stir contents there-above is disclosed herein. A motor turning the impeller is offset from a center line extending vertically through the device. The impeller, however, is centered with fan blades pushing air downwards as heat rises from a heat source placed there-below, such as between legs which support the impeller and bowl of the device, the bowl being used to hold a flask and/or substances to be heated. In this manner, the electric parts (the motor) and spared the brunt of the heat by being off-center while the heat rises upwards. The fan blades, in turn, dissipate some of the upward extending heat in order to more evenly heat the substances there-above the bowl. As the fan blades and magnets forming in impeller and within a same housing, only a single motor and belt are needed to rotate each. The simplification of parts leaves less points of potential failure compared to the prior art as does the movement of electric parts away from being above a heat source.

[0031] Embodiments of the disclosed technology will become more clear in view of the following description of the figures.

[0032] Discussing FIGS. 1 and 2, FIG. 1 shows a top and side exploded perspective view of a magnetic spinner system in an embodiment of the disclosed technology and FIG. 2 shows a bottom and side exploded perspective view thereof. From bottom to top, feet 90 support support legs 42. The feet are adjustable height and in some embodiments, have a screw or elongated connected extending upwards through legs 42. The legs can fasten to the feet by rotatably connected to same. A spaced 50 attaches or rests on the legs 42. The attachment mechanism, in one embodiment of the disclosed technology, are threaded caps 40 which thread onto the legs 42 such that the spacer 50 is between the caps 40 and legs 42. There can be three, four, five, or more legs with corresponding feet and portals 52 of the spacer 50. The portals 52 are where connector regions of the legs 42 pass through to connect to the caps 40.

[0033] Now discussing the spacer and elements attached thereto, a lower housing 70 is abutted and/or connected to and/or held against the spacer. The lower housing 70 can be held in place by way of a portal attached between one of the legs 42, spacer 50 (portal 52), and a cap 40. The lower housing has a motor 80 whose business end (spindle 5 which rotates) extends through a lower portal (unnumbered) of he lower housing 70 and connects to a reel 62, which is a type of washer or gear with teeth around the circumference. A belt 60 causes rotation of one of the reels to rotate the other reel. The reel situated directly over the motor 80 is off-center. When center is used in this disclosure, this refers to a vertical line which passes through the portal 54 of the spacer 50 and which is typically equidistant from the legs 42 and/or passes through the spindle 5 (lower elongated extent) of the top housing 30.

[0034] The off-center placement of the motor allows heat generated by a heat source below the device / parts shown in FIGS. 1 and 2 to rise without being blocked there-above by the motor. The heat generated also causes less harm or strain on the motor compared to a centered position motor since the heat can extend upwards more centered than the motor rather than being directly under the motor.

[0035] Returning now to the lower housing, the lower housing 70 is held against a lower side of the spacer 50. The top housing has a lower spindle 5 which extends into one of the reels 62. Washers 32, 34, and 36, which are above, within, and below the portal 54 of the spacer (in some embodiments) reduce friction allowing the upper housing 30 to spin as the spindles 62 spin. The upper housing 30 is centered at the spindle. The upper housing comprises a top portal which is discussed in more detail below.

[0036] Within the top portal are wider sections 1 and 2 as well as a narrow section 4 made narrower by a flange extending into what would otherwise be a rectangular portal, in embodiments of the disclosed technology. A bottom side of the upper housing 30 has an indented region 3 surrounded by, or mostly by, or partially by a lip 5. The lip can be of any size or shape and prevents rectangular prism or other shaped upper magnets from falling into the indented region. The magnets 22 and 24 are spaced apart, leaving a space in the center of the upper housing allowing heat to rise there-above unhindered by the magnets at the center line / center area of the devices (e.g. a vertical line equidistant from the legs 42).

[0037] The magnets 22 and 24 are sized such that in at least one orientation, and in some embodiments, two orientations, and in some embodiments, three orientations each 90 degrees offset from one of the other orientations, the magnets are unable to rest flat within the indented region 3. A plate 26 fits within indented region such that a most elongated and second most elongated distance at right or perpendicular angles to each other are normal to the vertical center. The magnets 22 and 24 abut the plate 26 magnetizing the plate 26 such that a magnetic field extends across the plate 26. This magnetic field is stronger than the two magnets separately as it joined into a single extended magnetic field, comparatively. It should be understood that any magnetic configuration can be used in other embodiments of the disclosed technology as long as the magnets are able to turn an impeller by way of magnetic force.

[0038] A bowl 20 is situated above the elements 1 to 4 and 28 to 90 in embodiments of the disclosed technology. The bowl can have a flask, glassware, or other device held therein along with a substance (solid, liquid, or combination thereof) to be heated and/or spun (stirred). The heat rising upwards can extend vertically with minimal blockage by parts between the bowl 20 and the heat source. These parts, in some embodiments, which are at the vertical center line are limited to, in some embodiments, the bowl 20, the plate 26 (which is made relatively thin and has a very low heat capacity), the upper housing 30, one of the reels 62, and the lower housing 70. The motor 80 and magnets 22/24 are outside of the vertical center in such embodiments of the disclosed technology.

[0039] Referring now specifically to FIG. 2, fan blades 38 are shown which spin with the upper housing 30 causing air, in some embodiments, to be pushed downwards causing a more even flow of upward air towards the bowl 20.

[0040] Referring now to FIGS. 3, 4 and 5, FIG. 3 shows a top and side perspective view thereof. FIG. 4 shows a bottom and side perspective view thereof. FIG. 5 shows a side elevation view thereof. The bowl 20 is seen with an interior region 28. The interior region is where a flask and/or material to be heated and/or stirred in placed. The upper housing 30 is shown above a washer 34, spacer 50, and lower housing 70. The lower housing 70 is held against the spacer 50 by way of placement between a leg 52 and cap 40. The motor 70 is seen off-center and the fan blades 38 are seen at the bottom side of the top housing 30. The fan blades dissipate heat above the separator 50 such that the heat has turbulent flow outwards and up towards the entire base of the bowl making for even heating at the bottom side of the bowl. The fan blades can have spaces above and below or terminate at a solid upwards side such that portals are between the blades which open only at a bottom side.

[0041] FIG. 6 shows an elevation view thereof with a heat source below the magnetic spinner system. FIG. 7 shows a bottom plan view thereof. FIG. 8 shows a top plan view thereof.The heat source 99 can be from a flame/fire or other sources of heat known in the art. In some embodiments, the heat source 99 is centered or substantially centered below the bowl.

[0042] FIG. 9 shows a side elevation view thereof with a flask placed therein. The flask 27 has an impeller 29 at the bottom thereof which substantially has an equal length from one end to an opposite end as that the bowl 28. This allows for efficient turning of the impeller 29 with the top housing 30.

[0043] Referring now to the upper housing in specific, FIG. 10 shows a top perspective view of the upper housing thereof. FIG. 11 shows a bottom perspective view of the upper housing thereof. FIG. 12 shows a side cutaway view of the upper housing thereof. The upper housing 30 is circular in embodiments of the disclosed technology so that it can rotate evenly. The centrifugal force while spinning causes the substances, magnets, to be forced towards the outer edges of the upper housing. The magnets, such as rectangular prism magnets, fit into each of the wider regions 1 and 2 respectively. The narrower region 4 has flanges extending towards each other as shown which prevents the magnets in each cavity 1 and 2 from moving towards each other, blocked in place by the narrow region 4. An indentation 3 is sized to fit a plate such as a metal and/or magnetizable plate having low heat capacity (1000 Joules per kilogram degree Celsius).

[0044] On the bottom side of the upper housing 30 the fan blades 38 are visible which are, in embodiments of the disclosed technology, which are fixed with and form a unitary structure with the body of the upper housing 30. The fan blades therefore spin with the upper housing 30 causing air to be pushed downwards. The spindle 5 can have a plurality of descending circumference sections which are each sized to fit in a washer, such as washers 32, 34, and 36 while the end of the spindle is rotatably connected within one of the reels 62.

[0045] While the disclosed technology has been taught with specific reference to the above embodiments, a person having ordinary skill in the art will recognize that changes can be made in form and detail without departing from the spirit and the scope of the disclosed technology. The described embodiments are to be considered in all respects only as illustrative and not restrictive. All changes that come within the meaning and range of equivalence of the claims are to be embraced within their scope. Combinations of any of the methods, systems, and devices described herein-above are also contemplated and within the scope of the disclosed technology.
