CROSS-REFERENCE TO RELATED APPLICATIONS This application is a divisional of U.S. Patent Application Ser. No. 11/578,320, filed Oct. 12, 2006, now U.S. Pat. No. 7,438,463 B2, which is a national phase filing of PCT/US05/011584, filed Apr. 5, 2005, which claims priority to U.S. Provisional Application No. 60/568,908, filed May 7, 2004, the details of both of which are hereby incorporated by reference as if fully set forth herein.
TECHNICAL FIELD The present application is directed to a bowl that can be pivotally coupled to a mixer, and to a mixer system having a pivotal bowl.
BACKGROUND Mixers are used to mix and blend a wide variety of materials. The mixers typically include a mixer body having a motor that drives a generally vertically-extending mixing element, and a bowl that is located below the mixing element. The bowl receives the materials to be mixed and the lower end of the rotatable mixing element therein. The bowl is typically detachable from the mixer body to aid in loading and unloading the materials into the bowl, and to enable cleaning, repair or replacement of the bowl.
SUMMARY A mixer has a bowl that is pivotally coupled to the mixer body, enabling the bowl to pivot away from the mixer body, which can provide increased access to the bowl. The bowl may include a magnetic sensor actuator thereon for triggering a magnetic sensor on the mixer body when the bowl is in a certain position, such as a closed position. The magnetic sensor, or some other type of sensor, may act as a single sensor that determines when the bowl is both in a bowl closed and bowl up position. The mixer body may also include a bowl retainer or holder that includes a curved surface that interacts with a curved surface on a bowl protrusion or stabilization member, facilitating slight tilting of the bowl when moved into or out of its closed position relative to the mixer body.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of one embodiment of a mixer;
DETAILED DESCRIPTION Referring to FIGS. 1 and 2, a mixing machine 10 includes a mixer body 12 having a base portion 14, a head portion or overhang portion 16 and a support portion 18 (e.g., in the form of a column or pedestal) connecting the head portion and the base portion in a vertically spaced apart relationship. A front to back head portion axis A is shown. An output member 20 (e.g., a shaft for receiving a mixer tool such as a beater or whip) extends downward from the head portion 16 in a direction toward a bowl receiving location 22 formed between the arms 24 of a bowl receiving yoke 25 that can be moved upward and downward relative to the head portion 16 by rotation of the illustrated handle 27. In one example, the handle 27 operates a gear system within the column that is linked to the yoke 25 and the yoke 25 is mounted for sliding movement along spaced apart tracks 29 at the front side of column 18 when the handle 27 is rotated. A motor 26 may be mechanically linked to the output member 20, as by a gear system 28, for effecting rotation of the output member about a first axis 30 and orbiting movement of the output member 20 and first axis 30 about a second axis 32 (e.g., a planetary movement or planetary rotation). A power take off 34 extends outwardly from a front side of the head portion 16 and may take the form of a protruding hub or boss that is adapted for connection with mixer accessories such as meat grinders, slicers etc. Internal of the power take off 34 is a drive member that is rotated by the motor 26 via the gear system 28. Head cover 40 is shown installed in FIG. 1, but is removed in FIG. 2.
Referring now to FIGS. 3-4, a bowl 50 includes bowl body 52 with upper opening 54 for receiving material to be mixed, and substantially diametrically opposed handles 56 (not shown in FIG. 3) extending from the bowl body for carrying the bowl 50. Pivot hinge components are also provided. Notably, vertically spaced apart brackets 58 and 60 each include a respective opening 62 and 64, with openings 62 and 64 aligned circumferentially and arranged vertically one above the other. A single bracket with two outwardly projecting parts could also be used to provide the openings. In the illustrated embodiment, the body of bracket 58 completely surrounds opening 62. Opening 64 is only partially surrounded by the body of bracket 60, such that opening 64 is open at an edge facing radially outward from a center axis 66 of the bowl. However, variations are possible. The rear part of the bowl includes a stabilization bracket 68 extending therefrom at a position about midway down the depth or height of the bowl body 52. Located above and substantially in circumferential alignment with the stabilization bracket 68, a sensor actuator 70 is positioned near the upper rim 72 of the bowl. For the purpose of this application, the rear of the bowl is defined as the part of the bowl that is positioned adjacent the mixer body when the bowl is mounted in a closed position on the mixer body as shown in FIG. 6. Sensor actuator 70 and stabilization bracket 68 are circumferentially spaced from both the brackets 58 and 60, and the locking bracket 90 (described below) by about 90 degrees.
Referring now to FIG. 7, an enlarged partial view of one embodiment of the pin 74 in cooperation with the brackets 58 and 60 of bowl 50 is shown. In this embodiment brackets 58 and 60 extend from a common bracket link 100. Upper part 102 of pin is tapered or rounded for ease of receiving the opening of bracket 58. Lower part 104 of pin 74 includes a cutout or cutaway 106 (best seen in the partial cross-section of FIG. 8) at its rearward facing side to provide a slight rearwardly located spacing 108 (FIG. 7) between the opening of bracket 60 and the pin part 104. This spacing 108 facilitates slight tilting of the bowl in the direction of arrow 110 when the bowl is moved to or from its closed position as described above. In one embodiment the bracket 60 may actually be in a non-contacting position relative to lower pin part 104 when the bowl is in the closed position, with bracket 60 only contacting lower pin part 104 when the bowl is pivoted out of the closed position.
