In addition, like reference numerals in the specification and drawings represent like elements.

[0023] For the purpose of this description, the terms "upper", "lower", "right", "left", "rear", "front", "vertical", "horizontal" and their derivatives shall be used in the same manner as described herein. Figure 1 The disclosure herein is related to the disclosure of orientation. Unless otherwise specified, the term "front" shall refer to the surface of the element that is closer to the intended observer, and the term "rear" shall refer to the surface of the element that is away from the intended observer. However, it should be understood that the disclosure may take various alternative orientations unless expressly stated to the contrary. It should also be understood that the specific devices and processes shown in the drawings and described in the following description are merely exemplary embodiments of the inventive concepts defined in the appended claims. Therefore, unless the claims expressly state otherwise, specific dimensions and other physical characteristics related to the embodiments disclosed herein should not be considered limiting.

[0024] The terms "comprises," "includes," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but may also include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element followed by "comprises..." does not, without more limitations, preclude the presence of more of the same element in the process, method, article, or apparatus that includes that element.

[0025] Ordinal modifiers (i.e., "first," "second," etc.) may be used to distinguish various structures of the disclosed articles in various contexts, but such ordinals are not necessarily intended to apply to such elements outside the specific context in which they are used, and in various aspects, different elements of the same class of elements may be identified with the same context-specific ordinal number. In such cases, the otherwise specific names of the elements are used to clarify the overall relationship between such elements. Ordinals are not used to specify the position of elements, nor do they exclude additional or intervening non-sequential elements, nor do they indicate the importance or ranking of an element within a particular class.

[0026] For purposes of this disclosure, the term "coupled" (and all its forms) generally refers to the connection of two components (electrical or mechanical) directly or indirectly to one another.

[0028] Reference Figures 1 to 6 , reference numeral 10 generally designates a citrus juicer. The citrus juicer 10 includes a base unit 12 including a housing 14 ( Figure 5 The housing 14 defines a battery receiving cavity 18 along a portion thereof, a plurality of terminals 20 ( Figure 2) is exposed in the battery receiving cavity 18. The citrus juicer 10 also includes a reservoir assembly 22 that can be mounted on the base unit 12 and encloses the liquid receiving cavity 24, and a juice extraction device 26 that is rotatably mounted at least partially within the liquid receiving cavity 24 and is configured to be driven by the motor 16 when the reservoir assembly 22 is mounted on the base 12. A battery 28 can be mounted in the battery receiving cavity 18 in electrical connection with the plurality of terminals 20, so that the base unit 12 is configured to operably power the drive motor 16 using the battery 28.

[0029] As will be appreciated, the use of the battery 28 to power the drive motor 16 allows the citrus juicer 10 described herein to be operated without having to plug the citrus juicer 10 into an external power source (e.g., a wall outlet, etc.), and results in the disclosed characterization of the citrus juicer 10 as being "cordless." In this manner, the citrus juicer 10 may be placed and operated in any convenient location along the counter space provided within a kitchen, regardless of the proximity of such location to an electrical outlet or available electrical outlets. Figure 2 As shown, the battery 28 is removably coupled with the housing 14 of the base 12 within the depicted battery receiving cavity 18 so that a selected battery 28 of a potentially plurality of available compatible batteries 28 can be selected and attached to the citrus juicer 10 by way of electrical connection facilitated by connection of the terminals of the battery 28 with the terminals 20 of the citrus juicer 10 exposed within the battery receiving cavity 18 to power its operation. In this manner, the battery 28 can be removed from the citrus juicer 10 for use with another compatible kitchen appliance (e.g., a hand mixer, hand blender, countertop blender, or food processor), or replaced with a rechargeable battery 28, such as when the current battery 28 has been depleted. In this manner, a depleted battery can be recharged using a compatible charger having mechanical components similar to the battery receiving cavity 18 and terminals 20 shown in conjunction with the citrus juicer 10 of the present invention. An example of such a charger is described in co-pending, commonly assigned U.S. provisional patent application having attorney docket number SUB-15280F-US-PSP [2] filed concurrently with the present application, the entire contents of which are incorporated herein by reference.

[0030] A battery 28 and corresponding electronic circuitry 30 (eg, a battery 28 for controlling the operation of the citrus juicer 10, including the operation of the drive motor 16) are provided. Figure 5) can be configured according to an architecture that utilizes voltages in the range of approximately 10-12V, and in one implementation, 12V, wherein it is understood that the actual voltages provided and utilized may vary within a range about the described desired operating voltages according to factors generally understood in the art. Generally, such voltages may be sufficient for operating the citrus juicer 10 at acceptable operating speeds and with acceptable torques for generally acceptable use of the citrus juicer 10, including operating the motor 16, which is generally understood to be a direct current (DC) motor and in one aspect is understood to be a brushless DC motor. Additional aspects of the battery-powered electrical operation of the citrus juicer 10 are further described below.

[0031] Reference Figures 1 to 6 , certain features of the disclosed citrus juicer 10 can increase the usability or overall performance of the device in a manner that does not necessarily rely on the use of the above-described battery 28 to exhibit such an effect. In one aspect, the citrus juicer 10 may include a plug-in interface between the reservoir assembly 22 and the base unit 12. Generally, the base 12 is configured to rest on a countertop surface, with the reservoir assembly 22 supported on the base 12. A motor 16 housed in the base 12 rotates a drive shaft 34 extending from the center of an upper protrusion 36 on an upper surface 32 of the base 12. The reservoir assembly 22 can be mounted on the base 12 by receiving the protrusion 36 within a lower cavity 38 defined on the reservoir assembly 22. As Figure 2 and Figure 5 As shown, the protrusion 36 can define at least one alignment tab 40 extending outwardly along the upper surface 32 of the base 12 away from the drive shaft 34. In this regard, the reservoir assembly 22 can include a bowl body 42 defining the lower cavity 38 of the reservoir assembly 22, and the bowl body 42 can define at least one recess 44 corresponding to the alignment tab 40 for when the reservoir assembly 22 is moved substantially vertically toward the base unit 12 through the bowl body 42 (e.g., from a position similar to Figure 2 The location shown to Figure 1 When the bowl 42 is mounted on the base unit 12 in the position shown in the figure, the alignment tab 40 is received in the recess 44. In one aspect, the current arrangement used to couple the reservoir assembly 22 to the base 12 can be characterized as a plug-in connection. In particular, the arrangement allows the bowl 42 to couple with the base 12 when it is lowered into place over the protrusion 36, without requiring any twisting to engage a coupling that may be associated with, for example, a threaded or bayonet-style attachment.

[0032] exist Figure 2In the illustrated arrangement, for example, the base 12 includes two tabs 40 extending outwardly from the protrusion 36, and the bowl 42 includes two corresponding recesses 44 that align with the tabs 40. In one example, the tabs 40 can be of different sizes and / or shapes (or in asymmetrical relative positions) so that the bowl 42 can only be oriented in one orientation (e.g., Figure 1 The reservoir assembly 22 is assembled to the base 12 in an orientation. This arrangement helps prevent rotation of the reservoir assembly 22 relative to the base unit 12, including under the torque of the motor 16 transmitted by the drive shaft 34, which is further discussed below.

[0033] In addition, the bowl body 42 defines the above-mentioned liquid receiving cavity 24 and includes a lower wall 46. The lower cavity 38 of the reservoir assembly 22 can be defined within the lower wall 46 so as to extend inwardly from the lower wall 46. In this regard, the cavity 38 can be inserted relative to the side wall 48 of the bowl body 42, and the side wall 48 extends upward from the lower wall 46 to further define the liquid receiving cavity 24. In this arrangement, the protrusion 36, which can be generally circular in shape in addition to the tab 40, can be fitted within the cavity 38 in a manner that is generally in close contact with the cavity 38, so that the bowl body 42 is generally positioned relative to the base 12 so that the lower wall 46 rests on the upper surface 32. As shown in FIG. Figure 5 As shown, the side wall 48 may extend downwardly beyond the lower wall 46 to visually engage the base 12 such that the inwardly disposed lower cavity 38 is at least partially obscured.

[0034] like Figure 2 and Figure 5 As shown, a stop feature 50 may be defined between the recess 44 and the protrusion 36, which stop feature 50 may be configured to be engaged when the reservoir assembly 22 is moved to the installed position ( Figure 1 ), the user feedback comprising the protrusion 36 being received into the recess 44. In the present example, at least one alignment tab 40 may include a spring biased ball 52 that may conformably engage with a corresponding cavity 54 in the aligned recess 44 to provide a snap fit between the bowl 42 and the base unit 12, which may particularly increase the retention of such fit. In another aspect, the detent mechanism 50 may be used as an interlock configured to prevent activation of the motor 16 in the absence of the bowl 42 on the base 12, but in the present example, the detent mechanism 50 is included simply for feedback and / or retention. In various examples, a similar detent mechanism 50 may be included between each tab 40 and the recess 44, but some arrangements may include only one detent mechanism 50.

[0035] The bowl 42 is sized to hold the juice output from the fruit (including larger fruits such as grapefruit or multiple oranges, lemons, etc.) for dispensing when juicing is complete. Figure 3 and Figure 4 As shown, the reservoir assembly 22 includes a dispensing spout 25, which can be integrally formed with the bowl 42, for example. In the example shown, the flap valve 56 is hingedly or otherwise rotatably coupled to the dispensing spout 25 and / or the adjacent bowl 42, and can be biased toward a closed position above the spout 25 ( Figure 3 In this arrangement, the user can press the opening lever 58 on the flap valve 56 to open the valve 56 ( Figure 4 ) and distribute the collected juice from the liquid receiving chamber 24. In one aspect, the valve 56 can have a bistable biasing arrangement, wherein once the valve 56 is moved to the fully open position ( Figure 4 ), valve 56 remains open until closed by the user. It is noteworthy that the height of base 12 positions spout 25 at a height configured to accommodate relatively tall containers (such as mixing bowls, large glasses, etc.).

[0036] Return to reference Figure 1 and Figure 2 In addition to the bowl 42, the reservoir assembly 22 may also include a filter 60 (also referred to as a screen) removably disposed in the bowl 42. In this manner, the bowl 42 may define an internal support 62 through which the drive shaft 34 extends. The internal support 62 may define a flange 64 that at least partially supports the filter 60 within the top of the bowl 42. The filter 60 is configured to capture pulp, seeds, and other solid matter while allowing the extracted juice to collect in the liquid receiving chamber 24. In this arrangement, the juice extraction device 26 is in the form of a press 26 that is centrally mounted within the bowl 42 and the filter 60. In one aspect, the press 26 is rotationally located above an upper portion of the internal support 62. The press 26 is connected to the drive shaft 34 through the internal support 62 and, therefore, the filter 60, such that rotation of the drive shaft 34 causes rotation of the press 26 to extract juice from the fruit that is squeezed into engagement therewith. As shown, the squeezer 26 may include a plurality of ribs 66 that intersect in a tip 68 and are configured to aid in extracting juice from the citrus fruit.

[0037] In operation, the juicer 10 is configured to release the juicer 26 when the juice extraction device 26 is depressed at a force above a predetermined threshold (i.e., by being depressed downward by an engaged cut citrus fruit, such as Figure 5 When the motor 16 is rotated to a predetermined degree (as shown in FIG. 1 ), the operation of causing the rotation of the juice extraction device 26 is initiated. More specifically, the juice extraction device 26 can move into the liquid receiving chamber 24 in the downward direction D against the upward spring bias. As described above, such movement of the juice extraction device 26 in the downward direction D can operate the switch 67, which is configured to initiate the operation of the motor 16 to drive the juice extraction device 26.

[0038] like Figure 6 As shown, during operation, the juicer 10 can continuously reverse the rotational direction R1 and R2 of the juice extraction appliance 26. This arrangement is facilitated by using a DC motor 16 powered by the above-mentioned battery 28. In one aspect, the above-mentioned electronic circuit 30 can include a controller in the form of a microprocessor or the like, which can include programming to operate the citrus juicer 10, including based on the state of the above-mentioned switch 66. In various aspects, the programming can include firmware or software specifically adapted to operate the motor 16 via the current received from the battery 28. In one example, the programming can be adapted to start the operation of the motor 16 when the switch 66 is pressed, and to reverse the operating direction R1, R2 of the motor 16 at predetermined intervals during operation (e.g., as long as the switch 66 remains in the pressed state) to cause oscillating rotation of the juice extraction appliance 26. In one example, the motor 16 can reverse after rotating 360° in each direction (or after a time interval of, for example, between 2 seconds and 5 seconds). In addition, after each successive deactivation and reactivation of the juicer 10 by the switch 66, the direction R1, R2 can be opposite to the previous direction.

[0039] return Figure 2 , the battery receiving cavity 18 can be configured to receive the battery 28 in a releasably retainable arrangement by the battery 28 being moved into the battery receiving cavity 18 in a radial direction relative to the base unit 12. In the example shown, the battery receiving cavity 18 is positioned above the bottom surface 71 of the base unit 12. Figure 2 As further shown, the battery 28 is adapted to be in a snap-fit ​​arrangement with the battery receiving cavity 18, wherein the battery 28 is moved toward the battery receiving cavity 18 in a lateral direction L and pressed into engagement therewith. In this arrangement, the terminals 20 of the battery receiving cavity 18 engage with the aligned battery terminals to electrically connect with the battery 28 when the battery 28 is fully received in the battery receiving cavity 18. As shown, the battery 28 may include spring-loaded tabs 70 that are urged outwardly so that they may be moved inwardly by initial engagement with corresponding notches 72 in the battery receiving cavity 18, and then moved outwardly behind the notches 72 when the battery 28 is fully received in the battery receiving cavity 18 to be fixedly held thereby. When the battery 28 is to be removed, a button 74 associated with the tabs 70 may be pressed to move the tabs 70 inwardly, thereby releasing them from the notches 72. As further shown, when used with the citrus juicer 10, the battery 28 is positioned with its charge level indicator light 76 pointing upward for visibility.

[0040] Go to Figures 8 to 11, (where like features are shown with like reference numerals as used above increased by 100 and where all features are substantially similar unless otherwise discussed herein) shows an alternative arrangement of valve 156 wherein, as described above, bowl 142 defines a valve housing 178 extending from bowl 142 adjacent a lower portion of liquid receiving chamber 124. A fluid outlet in the form of a downwardly angled dispensing spout 125 communicates with a sidewall 180 of valve housing 178 to define a fluid flow path from liquid receiving chamber 124. Valve body 159 is rotatably coupled within valve housing 178 and is movable to Figure 8 and Fig. 9 When in the closed position, the valve body 159 (a portion of the valve body 159) extends above the intersection of the fluid outlet 125 and the valve housing 178 so as to contact the inner surface of the side wall 180 in the area around the intersection, thereby closing the flow path to the dispensing spout 125. In this arrangement, the closure of the fluid flow path retains the liquid L in the liquid receiving chamber 124. The valve body 159 can also be moved to Fig.10 and Fig.11 The dispensing position shown, in which the intersection of the valve housing 178 and the dispensing spout 125 is not covered by the valve body 159. In this position, the fluid flow path out of the liquid receiving chamber 124 is open, so that any liquid L collected therein can be dispensed. In this arrangement, the valve body 159 can be at least partially enclosed by the knob 158, and the valve body 159 can be coupled to the knob 158 (in one aspect, including by being integrally formed therewith). The knob 158 can be used to manipulate the position of the valve body 159 to selectively open and close the fluid flow path out of the liquid receiving chamber 124. In one aspect, the arrangement of the valve body 159 within the valve housing 178 can be characterized as a butterfly valve, which can be moved between an open position and a closed position by a user rotating the knob 158 so that the valve moves through a "quarter turn" motion (i.e., 90° or less, including in either direction from a zero or closed position), and the knob 158 can include a ridge 182 or other indicator of its position. In an alternative arrangement, the position of the valve body 159 may be controlled by a lever or other similar structure.
