Abstract
Abstract A cotton candy making apparatus includes a hollow rotary member to be rotated, the rotary member being provided with a supply port for supplying sugar to the interior thereof and path for delivering molten sugar to a peripheral edge of the rotary member, a heating device located below the rotary member to heat the rotary member and hence heat and melt sugar in the rotary member, a fan for producing an air flow to the rotary member, the fan being rotated together with the rotary member, and a deflection device arranged between the fan and the heating device to guide the air flow from the fan to the peripheral edge of the rotary member. The rotary member has an extended flange extending radially outward from the peripheral edge of the rotary member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
An apparatus for making a cotton candy, comprising: an electric motor having an output shaft extending upward; a fan rotated together with the output shaft to produce an upward air flow; heater means arranged above the fan; a rotary member arranged above the heater means and rotated together with the output shaft, the rotary member being provided with a sugar chamber defined inside the rotary member and path means for guiding molten sugar from the sugar chamber melted by heat from the heater means to a peripheral edge of the rotary member, the path means having openings open at the peripheral edge of the rotary member; and deflecting means, disposed between the heater means and the fan, for deflecting air flow from the fan upon rotation thereof toward the peripheral edge of the rotary member.
Claim 2
Independent Claim
135 words
An apparatus for making a cotton candy, comprising: an electric motor having an output shaft extending upward; a fan rotated together with the output shaft to produce an upward air flow; heater means arranged above the fan; a rotary member arranged above the heater means and rotated together with the output shaft, the rotary member being provided with a sugar chamber defined inside the rotary member and path means for guiding molten sugar from the sugar chamber melted by heat from the heater means to a peripheral edge of the rotary member, the path means having openings open at the peripheral edge of the rotary member; and deflecting means, disposed between the heater means and the fan, for deflecting air flow from the fan upon rotation thereof toward the peripheral edge of the rotary member.
Claim 3
Dependent Claim
44 words
An apparatus according to claim 1, wherein the deflecting means includes a horizontal plate portion and a pair of inclined plate portions extending obliquely upward from at least two side portions of the horizontal plate portion toward the peripheral edge of the rotary member.
Claim 4
Dependent Claim
36 words
An apparatus according to claim 2, wherein surfaces of the horizontal and inclined plate portions which oppose the heater means are formed of reflecting surfaces for reflecting heat from the heater means toward the rotary member.
Claim 5
Dependent Claim
100 words
An apparatus according to claim 1, wherein the rotary member comprises a tray-like rotary vessel, a cover for covering an upper surface of the rotary vessel, the cover being provided with a central supply port for supplying sugar into the rotary vessel, and a partition member, disposed in the rotary vessel, for partitioning an interior of the rotary vessel into a radially inner chamber and a radially outer chamber, the sugar from the supply port being supplied to the radially inner chamber, and the path means extends from the radially inner chamber to the peripheral edge of the rotary member.
Claim 6
Dependent Claim
45 words
An apparatus according to claim 4, wherein the partition member includes a frustoconical hollow tapered pipe, a large-diameter open end of which is in contact with a bottom surface of the rotary vessel and a small-diameter open end of which communicates with the supply port.
Claim 7
Dependent Claim
26 words
An apparaturs according to claim 5, wherein an angle between the tapered pipe and the bottom surface of the rotary vessel is not more than 45°.
Claim 8
Dependent Claim
77 words
An apparatus according to claim 4, wherein the partition member comprises a hollow cylinder with a bottom wall and an open upper end, the bottom wall being in surface contact with a bottom surface of the rotary vessel, and the path means includes a plurality of slits in a peripheral wall of the hollow cylinder at predetermined intervals, the slits being adapted to extend from a bottom surface of the hollow cylinder along an axial direction thereof.
Claim 9
Dependent Claim
26 words
An apparatus according to claim 7, wherein the bottom wall of the rotary vessel has a hole for exposing the bottom wall of the hollow cylinder.
Claim 10
Dependent Claim
154 words
An apparatus according to claim 1, wherein the rotary member includes a coaxial connecting shaft, one end of which is coupled to the rotary member and the other end of which extends toward the output shaft of the electric motor and is connected thereto, the connecting shaft including a hole extending therethrough from said other end toward said one end of the connecting shaft to receive the output shaft and at least one slot formed in a lower end portion of the connecting shaft and extending from said other end toward said one end of the connecting shaft; and at least one radial pin member mounted on the output shaft of the electric motor, wherein the pin member can be fitted in the slot of the connecting shaft, said pin and said at least one slot comprising means for engaging and disengaging said connecting shaft and said output shaft by relative axial motion therebetween.
Claim 11
Dependent Claim
48 words
An apparatus according to claim 9, wherein the connecting shaft has a pair of slots formed in the connecting shaft at equal angular intervals, and the output shaft has a pair of pins extending in opposite radial directions and to be respectively fitted in the pair of slots.
Claim 12
Dependent Claim
44 words
An apparatus according to claim 9, wherein the connecting shaft has four slots formed in the connecting shaft at equal angular intervals, and the output shaft has a pair of pins extending in opposite radial directions and to be respectively fitted in the slots.
Claim 13
Dependent Claim
28 words
An apparatus according to claim 11, wherein the four slots are formed to constitute four arcuated surfaces in the hole of the connecting shaft at equal angular intervals.
Claim 14
Dependent Claim
14 words
