Mixing machine and associated bowl guard system
First Claim
Patent Images
1. A mixing machine, comprising:
- a mixer body including a head portion that extends over a bowl receiving location, the head portion including a magnetically actuatable bowl guard sensor thereon for providing a guard fault output;
an output member extending downward from the head portion toward the bowl receiving location;
a drive system including a motor mechanically linked to the output member for effecting planetary rotation of the output member, the drive system connected with the bowl guard sensor, the drive system and bowl guard sensor operate together such that in a first state of the bowl guard sensor planetary rotation of the output member can be effected by the drive system and in a second state of the bowl guard sensor planetary rotation of the output member cannot be effected by the drive system;
a bowl guard assembly including a first portion and a second portion, at least the second portion is movable to enable the bowl guard assembly to be arranged in both a bowl guarding orientation and a bowl access orientation, the second portion includes one of a magnet and a magnetically conductive path that moves with the second portion, the first portion includes the other of the magnet and the magnetically conductive path, wherein when the bowl guard assembly is in the bowl guarding orientation the magnet is positioned at a distance from the bowl guard sensor so that the magnetically conductive path is necessary in order for a magnetic field from the magnet to reach the bowl guard sensor and place the bowl guard sensor in its first state.

8. A mixing machine, comprising:
-
a mixer body including a head portion that extends over a bowl receiving location;
an output member extending downward from the head portion toward the bowl receiving location;
a motor mechanically linked to the output member for effecting planetary rotation of the output member;
a bowl guard support at an underside of the head portion, the bowl guard support providing a circular support path;
a bowl guard assembly including a first portion and a second portion, the second portion supported on the circular support path for rotation between a bowl guarding position relative to the first portion and a bowl access position relative to the first portion, wherein the second portion is removable from the bowl guard support via movement upward relative to the circular support path and laterally away from an upright axis of the circular support path. - View Dependent Claims (9, 10, 11, 12)

13. A mixing machine, comprising:
-
a mixer body including a head portion that extends over a bowl receiving location;
an output member extending downward from the head portion toward the bowl receiving location;
a motor mechanically linked to the output member for effecting planetary rotation of the output member;
a bowl guard support at an underside of the head portion;
a bowl guard assembly including a first portion and a second portion, the second portion supported on the bowl guard support for rotation between a bowl guarding position and a bowl access position relative to the first portion, wherein the second portion includes an upper support rim that extends through between about 60 and about 300 circumferential degrees such that a mounting gap is formed between ends of the upper support rim, the mounting gap extends through between about 300 and about 60 circumferential degrees to allow the upper support rim to move laterally onto and off of the bowl guard support. - View Dependent Claims (14, 15, 20)

21. A mixing machine, comprising:
-
a mixer body including a head portion that extends over a bowl receiving location, the head including a front side and a rear side, the rear side supported on a column of the mixer body;
an output member extending downward from the head portion toward the bowl receiving location;
a motor mechanically linked to the output member for effecting planetary rotation of the output member;
a bowl guard support ring assembly at an underside of the head portion to provide a circular support path, a stop positioned proximate to and along the circular support path; and
a bowl guard member having at least first and second guide members positioned on the circular support path for support and movable along the circular support path to enable the bowl guard member to rotate between a bowl guarding position and a bowl access position, wherein the first guide member is configured for contacting the stop to limit rotational movement of the bowl guard member and wherein the second guide member is configured to pass by the stop during rotational movement of the bowl guard member. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
