Shaved ice is a frozen confection produced from either large blocks of ice or small pieces (e.g., cubes) of ice via an ice shaving machine (or “ice shaver”). For example, a block ice shaver having a rotating blade may be used to produce shaved ice from a single large block of ice, or a cubed ice shaver having a stationary annular blade and a rotating paddle wheel (or “scraper”) wheel may be used to produce shaved ice from a plurality of small pieces or cubes of ice. In either case, the resulting shaved ice may be dispensed and subsequently flavored using one or more liquid toppings, such as syrup, to thereby produce a finished shaved ice product.
Conventional ice shaving machines include a stationary housing (e.g., a cabinet) which contains various internal components configured to produce shaved ice, such as a driven member (e.g., a rotating blade or ice scraper wheel) and a motor configured to selectively drive the driven member. Such ice shaving machines may further include a stationary spout having an outlet positioned external to the housing for dispensing the shaved ice into a cup, and a stationary shaping device (or “former”) configured to form a dome-shaped top on the dispensed shaved ice. Typically, the motor may be selectively activated by the user via an electromechanical switch in operative communication with the motor. Such a switch is usually positioned directly on the housing remotely from the spout and the former for manual actuation by the user. Thus, the user is required to position an empty cup below the spout and separately actuate the switch (e.g., with a separate hand from that holding the empty cup).
While certain ice shaving machines are known, it is believed that no one prior to the inventors has made or used the invention described in the appended claims.
The drawings and detailed description that follow are intended to be merely illustrative and are not intended to limit the scope of the invention as contemplated by the inventors.
The following description of certain examples of the invention should not be used to limit the scope of the present invention. Other examples, features, aspects, embodiments, and advantages of the invention will become apparent to those skilled in the art from the following description, which is by way of illustration, one of the best modes contemplated for carrying out the invention. As will be realized, the invention is capable of other different and obvious aspects, all without departing from the invention. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive.
I. Exemplary Ice Shaving Systems
In some instances, it may be desirable to provide an ice shaving machine (also referred to herein as an “ice shaving system”) having a spout and a former, where at least a portion of the spout and/or the former defines a movable structure being movable relative to a housing of the ice shaving machine, and further having a motor configured to drive a driven member (e.g., a rotating blade or scraper wheel) in response to user-actuation of the movable structure relative to the housing by a user. Providing activation of the motor responsive to the actuation of such a movable structure may enable improved user interaction with the ice shaving machine, such as by simplifying and/or reducing the user input required to produce shaved ice for a shaved ice product. Each of the exemplary ice shaving machines (110, 210, 310, 410, 510, 610, 710, 810, 910, 1010a, 1010b, 1110) described below functions in such a manner.
A. Exemplary Ice Shaving Machine Having Pivotable Former
Referring primarily to
In this regard, a driven member in the form of a rotatable ice scraper wheel (142) is positioned radially inwardly relative to annular blade (136) within shaving compartment (140). Scraper wheel (142) includes a central hub (144) and at least one paddle (146) extending radially outwardly from hub (144) toward annular blade (136). In the example shown, scraper wheel (142) further includes a plurality of drain holes (148), at least a portion of which are positioned along respective drain grooves (149) for promoting drainage of melted ice from shaving compartment (140).
Scraper wheel (142) is rotatable relative to annular blade (136) for applying centrifugal force to ice within shaving compartment (140) to thereby urge such ice radially outwardly toward and through annular blade (136). Paddle (146) is configured to push such ice against annular blade (136) and toward annular cavity (138) during rotation of scraper wheel (142). In this manner, annular blade (136) and scraper wheel (142) may cooperate to produce shaved ice from ice within shaving compartment (140) and deposit such shaved ice into annular cavity (138).
In the example shown, scraper wheel (142) is configured to be selectively driven by a motor (150) positioned within interior cavity (128) of housing (112). More particularly, hub (144) of scraper wheel (142) is operatively coupled to motor (150) via a transmission assembly or gearbox (152), which is also positioned within interior cavity (128) of housing (112) and which extends upwardly from motor (150) through mounting plate (126) to hub (144). Thus, activation of motor (150) may effect rotation of scraper wheel (142), as described in greater detail below.
Hopper (116) of the present example includes a generally dome-shaped cap (154) and an annular funnel (156) which collectively define a loading chamber (158) for receiving ice, such as cubed ice (CI). In the example shown, hopper (116) further includes an aperture (160) provided in cap (154) and a door (162) pivotably coupled to cap (154) for selectively permitting access to loading chamber (158) via aperture (160), such as for loading cubed ice (CI) into loading chamber (158). As best shown in
Spout (118) of the present example includes a generally elbow-shaped conduit (164) including a passageway (166) which terminates at an outlet (168) positioned external to housing (112) and hopper (116). In the example shown, passageway (166) is in communication with annular cavity (138) for receiving shaved ice therefrom. Passageway (166) is bent downwardly at an approximately 90° angle for redirecting such shaved ice from a radially outward flow path to a vertically downward flow path to thereby dispense the shaved ice downwardly via outlet (168).
Former (120) of the present example includes an open-ended cup guide or cup support (170) and a closed-ended dome (172). Cup support (170) is configured to receive and guide a cup during dispensing of shaved ice into cup from spout (118) and during subsequent advancement of the cup along an inner surface of cup support (170) toward dome (172) by the user. Dome (172) is configured to mold or otherwise form a dome-shaped top on the dispensed shaved ice when the cup is advanced toward dome (172) to pack the dispensed shaved ice against an inner surface of dome (172). In the example shown, cup support (170) and dome (172) are integrally formed together as a unitary piece. In other examples, cup support (170) and dome (172) may be separately formed from each other as distinct pieces, as described below. It will be appreciated that former (120) may be alternatively configured in other versions to shape the dispensed shaved ice with any desired predetermined shape.
Referring now primarily to
In this regard, a switch shown in the form of an electromechanical switch (180) is positioned on one pivot arm (174) and is in operative communication with motor (150) for activating motor (150) in response to pivoting of former (120) relative to housing (112) from the untriggered state to the triggered state. More particularly, former (120) is configured to actuate switch (180) when former (120) is pivoted from the untriggered state to the triggered state. To this end, switch (180) of the present example includes a resiliently-biased actuator (182), and former (120) includes a raised camming surface (184) extending radially outwardly from the respective sleeve (178) for selectively engaging actuator (182) during pivoting of former (120) from the untriggered state to the triggered state. Thus, pivoting of former (120) from the untriggered state to the triggered state, as indicated by first arrow (A1) in
Referring now to
While only one switch (180) is shown in the present example, it will be appreciated that any suitable quantity and arrangement of two or more switches (180) may be provided in other examples. In such configurations, each switch (180) may be configured to detect a corresponding one or more respective positions of the movable structure (e.g., former (120)) relative to housing (112) or another portion of ice shaving machine (110). Such multiple switches (180) may be positioned on ice shaving machine (110) in a variety of suitable locations in addition to or in place of the location shown and described herein, such that switches (180) are operable in the manner described herein. Additionally, while switch (180) is shown in the form of an actuatable electromechanical switch that is directly contacted by a movable structure of ice shaving machine (110), it will be appreciated that switch (180) may be any suitable type of electrical switch readily apparent to those of ordinary skill in the art in view of the teachings herein, including both contact switches and contactless switches. For instance, and by way of example only, switch (180) may alternatively be in the form of a magnetic switch, a pressure switch, a membrane switch, an inductive proximity sensor switch, a photoelectric sensor switch, or the like. In versions incorporating a contactless switch, it will be appreciated that the mere presence of a certain object (e.g., a cup), without actuating a movable structure, may be effective to trigger the contactless switch and thereby activate motor (150) for generating shaved ice. It will be further appreciated that such exemplary variations in the quantity, arrangement, and/or type of switch (180) may similarly apply to switches (280, 380, 480, 580, 680, 780, 880, 980, 1080, 1180) described below.
B. Exemplary Ice Shaving Machine Having Upwardly Translatable Former
Ice shaving machine (210) of this example comprises housing (112), spout (118), and a former (220) positioned below spout (118) in vertical alignment therewith for forming a dome-shaped top on the dispensed shaved ice. In other versions, at least a portion of former (220) may be laterally offset from spout (118)
Former (220) of the present example includes an open-ended cup guide or cup support (270) and a closed-ended dome (272), and is translatably coupled to housing (112) such that former (220) is translatable relative to housing (112) between the illustrated untriggered state and a triggered state. More particularly, at least one bracket (274) is fixed to housing (112) and includes at least one slot (275) which slidably retains at least one respective rail (276) extending laterally outwardly from dome (272) of former (220). Former (220) may be resiliently biased toward the untriggered state, such as via a tension or compression spring or any other suitable biasing member (not shown). In one example, motor (150) is configured to drive scraper wheel (142) in response to upward translation of former (220) relative to housing (112) from the untriggered state to the triggered state.
In this regard, a switch shown in the form of an electromechanical switch (280) is positioned on bracket (274) and is in operative communication with motor (150) for activating motor (150) in response to upward translation of former (220) relative to housing (112) from the untriggered state to the triggered state. More particularly, former (220) is configured to actuate switch (280) when former (220) is translated upwardly from the untriggered state to the triggered state. To this end, switch (280) of the present example includes a resiliently-biased actuator (282), and rail (276) of former (220) includes an upper surface for selectively engaging actuator (282) during upward translation of former (220) from the untriggered state to the triggered state. Thus, upward translation of former (220) from the untriggered state to the triggered state may cause the upper surface of rail (276) to apply a threshold force sufficient to urge actuator (282) upwardly, to thereby transition switch (280) from an unactuated, deactivation state to an actuated, activation state in which switch (280) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of actuator (282) may enable switch (280) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the upper surface of rail (276) to actuator (282), such as during downward translation of former (220) from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
During operation, a user may insert a cup (C) into cup support (270) of former (220) with the user's first hand (H1) and may subsequently lift former (220) with the user's second hand (H2) to translate former (220) in an upward direction from the untriggered state toward the triggered state, as indicated by sixth arrow (A6) in
C. Exemplary Ice Shaving Machine Having Downwardly Translatable Former
Ice shaving machine (310) of this example comprises housing (112), spout (118), and a former (320) positioned below spout (118) in vertical alignment therewith for forming a dome-shaped top on the dispensed shaved ice. In other versions, at least a portion of former (320) may be laterally offset from spout (118).
Former (320) of the present example includes an open-ended cup guide or cup support (370) and a closed-ended dome (372), and is translatably coupled to housing (112) such that former (320) is translatable relative to housing (112) between the illustrated untriggered state and a triggered state. More particularly, at least one bracket (374) is fixed to housing (112) and includes at least one slot (375) which slidably retains at least one respective rail (376) extending laterally outwardly from dome (372) of former (320). Former (320) may be resiliently biased toward the untriggered state, such as via a tension or compression spring or any other suitable biasing member (not shown). In one example, motor (150) is configured to drive scraper wheel (142) in response to downward translation of former (320) relative to housing (112) from the untriggered state to the triggered state.
In this regard, a switch shown in the form of an electromechanical switch (380) is positioned on bracket (374) and is in operative communication with motor (150) for activating motor (150) in response to downward translation of former (320) relative to housing (112) from the untriggered state to the triggered state. More particularly, former (320) is configured to actuate switch (380) when former (320) is translated downwardly from the untriggered state to the triggered state. To this end, switch (380) of the present example includes a resiliently-biased actuator (382), and rail (376) of former (320) includes a lower surface for selectively engaging actuator (382) during downward translation of former (320) from the untriggered state to the triggered state. Thus, downward translation of former (320) from the untriggered state to the triggered state may cause the lower surface of rail (376) to apply a threshold force sufficient to urge actuator (382) downwardly, to thereby transition switch (380) from an unactuated, deactivation state to an actuated, activation state in which switch (380) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of actuator (382) may enable switch (380) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the lower surface of rail (376) to actuator (382), such as during upward translation of former (320) from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
During operation, a user may insert a cup (C) into cup support (370) of former (320) with the user's first hand (H1) and may subsequently press the cup (C) against an inner surface of cup support (370), as indicated by seventh arrow (A7) in
D. Exemplary Ice Shaving Machine Having Former with Fixed and Pivotable Portions
Ice shaving machine (410) of this example comprises housing (112), spout (118), and a former (420) positioned below spout (118) in vertical alignment therewith for forming a dome-shaped top on the dispensed shaved ice. In other versions, at least a portion of former (420) may be laterally offset from spout (118).
Former (420) of the present example includes an open-ended cup guide or cup support (470) and a closed-ended dome (472). In the example shown, cup support (470) is pivotably coupled to dome (472), and dome (472) is fixedly coupled to housing (112) via a bracket (474) such that cup support (470) is pivotable relative to housing (112) between an untriggered state (
In this regard, a switch shown in the form of an electromechanical switch (480) is positioned on an outer surface of housing (112) and is in operative communication with motor (150) for activating motor (150) in response to pivoting of cup support (470) relative to housing (112) from the untriggered state to the triggered state. More particularly, cup support (470) is configured to actuate switch (480) when cup support (470) is pivoted from the untriggered state to the triggered state. To this end, switch (480) of the present example includes a resiliently-biased actuator in the form of a button (482), and cup support (470) includes an outer surface for selectively engaging button (482) during pivoting of cup support (470) from the untriggered state to the triggered state. Thus, pivoting of cup support (470) from the untriggered state to the triggered state may cause the outer surface of cup support (470) to apply a threshold force sufficient to depress button (482), to thereby transition switch (480) from an unactuated, deactivation state to an actuated, activation state in which switch (480) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of button (482) may enable switch (480) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the outer surface of cup support (470) to button (482), such as during pivoting of cup support (470) from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
During operation, a user may insert a cup (C) into cup support (470) of former (420) with the user's first hand (H1) and may subsequently press the cup (C) against an inner surface of cup support (470), as indicated by ninth arrow (A9) in
E. Exemplary Ice Shaving Machine Having Former with Button
Ice shaving machine (510) of this example comprises housing (112), spout (118), and a former (520) positioned below spout (118) in vertical alignment therewith for forming a dome-shaped top on the dispensed shaved ice. In other versions, at least a portion of former (520) may be laterally offset from spout (118).
Former (520) of the present example includes an open-ended cup guide or cup support (570) and a closed-ended dome (572). In the example shown, cup support (570) and dome (572) are fixedly coupled to housing (112) via a bracket (574) and a switch shown in the form of an electromechanical switch (580) is positioned on an inner surface of cup support (570) such that a resiliently-biased button (582) of switch (580) is depressible relative to housing (112) between the illustrated untriggered state and a triggered state. In one example, motor (150) is configured to drive scraper wheel (142) in response to depressing of button (582) relative to housing (112) from the untriggered state to the triggered state. In this regard, switch (580) is in operative communication with motor (150) for activating motor (150) in response to depressing of button (582) relative to housing (112) from the untriggered state to the triggered state.
During operation, a user may insert a cup (C) into cup support (570) of former (520) with the user's first hand (H1) and may subsequently press the cup (C) against button (582), as indicated by tenth arrow (A10) in
F. Exemplary Ice Shaving Machine Having Pivotable Spout
In some instances, it may be desirable to provide a motor-activation switch independently of a shaping device (or “former”) of the corresponding ice shaving machine. It will be appreciated that in some such versions, the former may be provided separately from the ice shaving machine. By way of example only, the former may be an independent handheld device; the former may be attached to a support structure that is separate and independent from the ice shaving machine; or the former may be omitted from use entirely. It will be appreciated that in any such versions, each of (i) an ice shaving machine without a former, and (ii) the combination of an ice shaving machine with an independent former, may be considered an “ice shaving system.”
Ice shaving machine (610) of this example comprises housing (112), a spout (618) extending external to housing (112) and/or hopper (116) for dispensing shaved ice from ice shaving machine (610), and a former (620) positioned below spout (618) in vertical alignment therewith for forming a dome-shaped top on the dispensed shaved ice. In other versions, at least a portion of former (620) may be laterally offset from spout (618).
Spout (618) of the present example includes a generally elbow-shaped conduit (664) including a passageway (not shown) which terminates at an outlet (668) positioned external to housing (112) and hopper (116). The passageway of conduit (664) may be in communication with annular cavity (138) for receiving shaved ice therefrom, and may be bent downwardly at an approximately 90° angle for redirecting such shaved ice from a radially outward flow path to a vertically downward flow path to thereby dispense the shaved ice downwardly via outlet (668). Former (620) of the present example includes an open-ended cup guide or cup support (670) and a closed-ended dome (672) fixedly coupled to housing (112) via a bracket (674). In the example shown, spout (618) is pivotably coupled to housing (112) such that spout (618) is pivotable relative to housing (112) between the illustrated untriggered state and a triggered state. More particularly, a pivot pin (676) pivotably couples an end of spout (618) opposite from outlet (668) to housing (112). Spout (618) may be resiliently biased toward the untriggered state, such as via a torsion spring or any other suitable biasing member (not shown). In one example, motor (150) is configured to drive scraper wheel (142) in response to pivoting of spout (618) relative to housing (112) from the untriggered state to the triggered state.
In this regard, a switch shown in the form of an electromechanical switch (680) is positioned on bracket (674) and is in operative communication with motor (150) for activating motor (150) in response to pivoting of spout (618) relative to housing (112) from the untriggered state to the triggered state. More particularly, spout (618) is configured to actuate switch (680) when spout (618) is pivoted from the untriggered state to the triggered state. To this end, switch (680) of the present example includes a resiliently-biased actuator (682), and conduit (664) of spout (618) includes a lower surface for selectively engaging actuator (682) during pivoting of spout (618) from the untriggered state to the triggered state. Thus, pivoting of spout (618) from the untriggered state to the triggered state may cause the lower surface of conduit (664) to apply a threshold force sufficient to urge actuator (682) downwardly, to thereby transition switch (680) from an unactuated, deactivation state to an actuated, activation state in which switch (680) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of actuator (682) may enable switch (680) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the lower surface of conduit (664) to actuator (682), such as during pivoting of spout (618) from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
During operation, a user may insert a cup (C) into former (620) with the user's first hand (H1) and may subsequently press spout (618) with the user's second hand (H2), as indicated by eleventh arrow (A11) in
G. Exemplary Ice Shaving Machine Having Upwardly Translatable Spout
Ice shaving machine (710) of this example comprises housing (112), a spout (718) extending external to housing (112) and/or hopper (116) for dispensing shaved ice from ice shaving machine (710), and former (620).
Spout (718) of the present example includes a generally elbow-shaped conduit (764) including a passageway (not shown) which terminates at an outlet (768) positioned external to housing (112) and hopper (116). The passageway of conduit (764) may be in communication with annular cavity (138) for receiving shaved ice therefrom, and may be bent downwardly at an approximately 90° angle for redirecting such shaved ice from a radially outward flow path to a vertically downward flow path to thereby dispense the shaved ice downwardly via outlet (768). In the example shown, spout (718) is translatably coupled to housing (112) such that spout (718) is translatable relative to housing (112) between the illustrated untriggered state and a triggered state. More particularly, at least one bracket (774) is fixed to housing (112) and includes at least one slot (775) which slidably retains at least one respective rail (776) extending laterally outwardly from conduit (764) of spout (718). Spout (718) may be resiliently biased toward the untriggered state, such as via a tension or compression spring or any other suitable biasing member (not shown). In one example, motor (150) is configured to drive scraper wheel (142) in response to upward translation of spout (718) relative to housing (112) from the untriggered state to the triggered state.
In this regard, a switch shown in the form of an electromechanical switch (780) is positioned on bracket (774), and is in operative communication with motor (150) for activating motor (150) in response to upward translation of spout (718) relative to housing (112) from the untriggered state to the triggered state. More particularly, spout (718) is configured to actuate switch (780) when spout (718) is translated upwardly from the untriggered state to the triggered state.

Thus, upward translation of spout (718) from the untriggered state to the triggered state may cause the upper surface of rail (776) to apply a threshold force sufficient to urge actuator (782) upwardly, to thereby transition switch (780) from an unactuated, deactivation state to an actuated, activation state in which switch (780) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of actuator (782) may enable switch (780) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the upper surface of rail (776) to actuator (782), such as during downward translation of spout (718) from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
During operation, a user may insert a cup (C) into former (620) with the user's first hand (H1) and may subsequently lift spout (718) with the user's second hand (H2) to translate spout (718) in an upward direction from the untriggered state toward the triggered state, as indicated by twelfth arrow (A12) in
H. Exemplary Ice Shaving Machine Having Spout with Lever
Ice shaving machine (810) of this example comprises housing (112), a spout (818) extending external to housing (112) and/or hopper (116) for dispensing shaved ice from ice shaving machine (810), and former (620).
Spout (818) of the present example includes a generally elbow-shaped conduit (864) including a passageway (not shown) which terminates at an outlet (868) positioned external to housing (112) and hopper (116). The passageway of conduit (864) may be in communication with annular cavity (138) for receiving shaved ice therefrom, and may be bent downwardly at an approximately 90° angle for redirecting such shaved ice from a radially outward flow path to a vertically downward flow path to thereby dispense the shaved ice downwardly via outlet (868). In the example shown, conduit (864) is fixedly coupled to housing (112) and a switch shown in the form of an electromechanical switch (880) is positioned on an upper surface of conduit (864) such that a resiliently-biased lever (882) of switch (880) is pivotable relative to housing (112) between the illustrated untriggered state and a triggered state. In one example, motor (150) is configured to drive scraper wheel (142) in response to pivoting of lever (882) relative to housing (112) from the untriggered state to the triggered state. In this regard, switch (880) is in operative communication with motor (150) for activating motor (150) in response to pivoting of lever (882) relative to housing (112) from the untriggered state to the triggered state.
During operation, a user may insert a cup (C) into former (620) with the user's first hand (H1) and may subsequently press lever (882) (e.g., with the user's second hand), as indicated by thirteenth arrow (A13) in
I. Exemplary Ice Shaving Machine Having Pivotable Former and Spout Assembly
Ice shaving machine (910) of this example comprises housing (112), a spout (918) extending external to housing (112) and/or hopper (116) for dispensing shaved ice from ice shaving machine (910), and a former (920) positioned at least partially below spout (918) for forming a dome-shaped top on the dispensed shaved ice.
Spout (918) and former (920) of the present example are directly, fixedly coupled to each other to define a combined unit (or “former and spout assembly”). More specifically, in the present example, spout (918) and former (920) are integrally formed to define a single unitary piece. In other examples, former (920) may be releasably coupled to spout (918) via any one or more suitable releasable coupling features (e.g., magnets) to define such a combined unit, for example as disclosed in U.S. Pat. No. 9,441,871, entitled “Shaping Device for a Shaved Ice or Snow Cone Product,” issued Sep. 13, 2016, the disclosure of which is incorporated by reference herein.
Spout (918) includes a generally straight conduit (964) including a passageway (not shown) which terminates at an outlet (968) positioned external to housing (112) and hopper (116). The passageway of conduit (964) may be in communication with annular cavity (138) for receiving shaved ice therefrom. Former (920) includes a cup guide or cup support (970) and a dome (972) having an inlet (973) which directly interfaces with outlet (968) such that the passageway of conduit (964) is in communication with an interior of former (920) for directing shaved ice into former (920) via outlet (968) and inlet (973). In the example shown, spout (918) and former (920) are collectively pivotably coupled to housing (112) such that spout (918) and former (920) are pivotable together relative to housing (112) between the illustrated untriggered state and a triggered state. More particularly, a pivot pin (976) pivotably couples an end of spout (918) opposite from outlet (968) to housing (112). Spout (918) and former (920) may be resiliently biased together toward the untriggered state, such as via a torsion spring or any other suitable biasing member (not shown). In one example, motor (150) is configured to drive scraper wheel (142) in response to pivoting of spout (918) and former (920) together relative to housing (112) from the untriggered state to the triggered state.
In this regard, a switch shown in the form of an electromechanical switch (980) is positioned on an outer surface of housing (112) and is in operative communication with motor (150) for activating motor (150) in response to pivoting of spout (918) and former (920) together relative to housing (112) from the untriggered state to the triggered state. More particularly, spout (918) is configured to actuate switch (980) when spout (918) and former (920) are pivoted together from the untriggered state to the triggered state. To this end, switch (980) of the present example includes a resiliently-biased actuator (982), and conduit (964) of spout (918) includes a rear surface for selectively engaging actuator (982) during pivoting of spout (918) and former (920) together from the untriggered state to the triggered state. Thus, pivoting of spout (918) and former (920) together from the untriggered state to the triggered state may cause the rear surface of conduit (964) to apply a threshold force sufficient to urge actuator (982) rearwardly, to thereby transition switch (980) from an unactuated, deactivation state to an actuated, activation state in which switch (980) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of actuator (982) may enable switch (980) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the rear surface of conduit (964) to actuator (982), such as during pivoting of spout (918) and former (920) together from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
During operation, a user may insert a cup (C) into cup support (970) of former (920) with the user's first hand (H1) and may subsequently press the cup (C) against an inner surface of cup support (970), as indicated by fourteenth arrow (A14) in
J. Exemplary Ice Shaving Machines Having Upwardly Translatable Former and Spout Assembly
Ice shaving machines (1010a, 1010b) of these examples each comprise housing (112), a spout (1018a, 1018b) extending external to housing (112) and/or hopper (116) for dispensing shaved ice from ice shaving machine (1010a, 1010b), and a former (1020) positioned at least partially below spout (1018a, 1018b) for forming a dome-shaped top on the dispensed shaved ice. Spout (1018a, 1018b) and former (1020) of the present examples are directly, fixedly coupled to each other and, more particularly, are integrally formed together as a unitary piece, to define a combined unit (or “former and spout assembly”). In other examples, former (1020) may be releasably coupled with spout (1018a, 1018b) so as to define a former and spout assembly.
Spout (1018a, 1018b) includes a generally straight conduit (1064a, 1064b) including a passageway (not shown) which terminates at an outlet (1068a, 1068b) positioned external to housing (112) and hopper (116). By way of comparison, conduit (1064b) of spout (1018b) illustrated in
In this regard, a switch shown in the form of an electromechanical switch (1080) is positioned on an outer surface of housing (112) and is in operative communication with motor (150) for activating motor (150) in response to upward translation of spout (1018a, 1018b) and former (1020) together relative to housing (112) from the untriggered state to the triggered state. More particularly, spout (1018a, 1018b) is configured to actuate switch (1080) when spout (1018a, 1018b) and former (1020) are translated upwardly together from the untriggered state to the triggered state. To this end, switch (1080) of the present example includes a resiliently-biased actuator (1082), and conduit (1064a, 1064b) of spout (1018a, 1018b) includes an upper surface for selectively engaging actuator (1082) during upward translation of spout (1018a, 1018b) and former (1020) together from the untriggered state to the triggered state. Thus, upward translation of spout (1018a, 1018b) and former (1020) together from the untriggered state to the triggered state may cause the upper surface of conduit (1064a, 1064b) to apply a threshold force sufficient to urge actuator (1082) upwardly, to thereby transition switch (1080) from an unactuated, deactivation state to an actuated, activation state in which switch (1080) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of actuator (1082) may enable switch (1080) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the upper surface of conduit (1064a, 1064b) to actuator (1082), such as during downward translation of spout (1018a, 1018b) and former (1020) together from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
During operation, a user may insert a cup (C) into cup support (1070) of former (1020) with the user's first hand (H1) and may subsequently lift former (1020) with the user's second hand (H2) to translate spout (1018a, 1018b) and former (1020) together in an upward direction from the untriggered state toward the triggered state, as indicated by eighteenth arrow (A18) in
K. Exemplary Ice Shaving Machine Having Former and Spout Assembly with Flexible Portion
Ice shaving machine (1110) of this example comprises housing (112), a spout (1118) extending external to housing (112) and/or hopper (116) for dispensing shaved ice from ice shaving machine (1110), and a former (1120) positioned at least partially below spout (1118) for forming a dome-shaped top on the dispensed shaved ice. Spout (1118) and former (1120) of the present example are directly, fixedly coupled to each other and, more particularly, are integrally formed together as a unitary piece, to define a combined unit (or “former and spout assembly”). In other examples, former (1120) may be releasably coupled with spout (1118) so as to define a former and spout assembly.
Spout (1118) includes a generally straight conduit (1164) including a passageway (not shown) which terminates at an outlet (1168) positioned external to housing (112) and hopper (116). The passageway of conduit (1164) may be in communication with annular cavity (138) for receiving shaved ice therefrom. Former (1120) includes a cup guide or cup support (1170) and a dome (1172) having an inlet (1173) which directly interfaces with outlet (1168) such that the passageway of conduit (1164) is in communication with an interior of former (1120) for directing shaved ice into former (1120) via outlet (1168) and inlet (1173). In the example shown, cup support (1170) is flexibly coupled to dome (1172), and dome (1172) is fixedly coupled to housing (112) via conduit (1164) such that cup support (1170) is flexible relative to housing (112) between an untriggered state (
In this regard, a switch shown in the form of an electromechanical switch (1180) is positioned on an outer surface of housing (112) and is in operative communication with motor (150) for activating motor (150) in response to flexing of cup support (1170) relative to housing (112) from the untriggered state to the triggered state. More particularly, cup support (1170) is configured to actuate switch (1180) when cup support (1170) is flexed from the untriggered state to the triggered state. To this end, switch (1180) of the present example includes a resiliently-biased actuator in the form of a button (1182), and cup support (1170) includes an outer surface for selectively engaging button (1182) during flexing of cup support (1170) from the untriggered state to the triggered state. Thus, flexing of cup support (1170) from the untriggered state to the triggered state may cause the outer surface of cup support (1170) to apply a threshold force sufficient to depress button (1182), to thereby transition switch (1180) from an unactuated, deactivation state to an actuated, activation state in which switch (1180) activates motor (150) to rotate scraper wheel (142). In one example, the resilient biasing of button (1182) may enable switch (1180) to automatically transition from the activation state to the deactivation state upon removal of the threshold force applied by the outer surface of cup support (1170) to button (1182), such as during flexing of cup support (1170) from the triggered state to the untriggered state, to deactivate motor (150) and cease rotating scraper wheel (142).
In some versions, flexible cup support (1170) itself may be used as a shaping device in addition to or in place of dome (1172) of former (1120) for shaping dispensed shaved ice. In some such versions, spout (1118), former (1120), and its flexible cup support (1170) may be further configured in accordance with at least some of the teachings of U.S. Pat. No. 6,527,212, entitled “Ice Shaver,” issued Mar. 4, 2003; and/or U.S. Pat. No. 10,443,916, entitled “Portable Frozen Confection Machine,” issued Oct. 15, 2019, the disclosures of each of these patents being incorporated by reference herein.
During operation, a user may insert a cup (C) into cup support (1170) of former (1120) with the user's first hand (H1) and may subsequently press the cup (C) against an inner surface of cup support (1170), as indicated by twentieth arrow (A20) in
As described above with reference to the exemplary ice shaving systems shown in
