Abstract
A blender for installation under kitchen cabinets includes a housing mounted underneath the cabinet with a shaft detent connection bushing extending downwardly from the housing connected to a motor which is electrically controlled to provide various speeds to the bushing into which a shaft disengagingly connects having blending blades at the lower end with a cup shaped container with annular threads at the top edge which engage annular threads on the bottom wall of the housing to seal the container around the blender shaft with a switch to shut off the power with the cup container is not in position.
Claims13
A blending device mountable on an underside of a wall mounted kitchen type cabinet comprising:
- (a) a housing having a top wall, a bottom wall and a front side wall,
- (b) a mounting means to mount the housing on the underside of a wall cabinet,
- (c) a shaft detent connection means extending through the bottom wall of the housing to disengageably connect to a shaft held vertically from the connection means,
- (d) a motor drive means to receive electrical current and rotatingly spin the connection means,
- (e) control means to vary the rate of rotation of the motor drive means,
- (f) wiring means to electrically connect the motor drive means and the control means to an electrical power source,
- (g) annular threads molded into and extending downwardly from the bottom wall of the housing positioned with the connection means in the center of the annular threads,
- (h) a cylindrical cup shaped container having an open top, a top edge of the cup around the periphery of the open top, a bottom, and annular threads proximate to the top edge of the container, the threads being of size and shape to engage the annular threads from the bottom wall and hold the container upright to the housing, and
- (i) the shaft having an upper end and a lower end disengagingly connected at the upper end to the connection means and a blender blade means secured to the lower end of the shaft and extending outwardly from the shaft to vigorously blend and mix liquids and solids in the container when rotated at a high rate of speed by the motor drive means.

- (b) a mounting means to mount the housing on the underside of a wall cabinet,
- (c) a shaft detent connection means extending through the bottom wall of the housing to disengageably connect to a shaft held vertically from the connection means,
- (d) a motor drive means to receive electrical current and rotatingly spin the connection means,
- (e) control means to vary the rate of rotation of the connection means comprising a plurality of buttons, one to turn the motor drive means off and the balance of the buttons to turn the motor drive means on and to adjust the speed of rotation of the connection means and the shaft,
- (f) wiring means to electrically connect the motor drive means and the control means to an electrical power source,
- (g) annular threads molded into and extending downwardly from the bottom wall of the housing positioned with the connection means in the center of the annular threads,
- (h) a cylindrical cup shaped container having annular threads proximate to a top edge the threads being of size and shape to engage the annular threads in the bottom wall and hold the container upright to the housing, and a convex area in a bottom of the cup shaped container the convex area extending upwardly into the container with a depression in the center of the convex area to receive a rounded lower end of the shaft, positioned such that the rounded lower end rests on and rotates in the depression,
- (i) a switch extending through the bottom wall where the top edge of the container abuts the bottom wall, depressing the switch when the container is threadably connected to the housing, wherein the switch is connected to the power source with the wiring means such that current is provided to the motor drive means only when the switch is depressed,
- (ii) the shaft having an upper end and a lower end disengagingly connected at the upper end to the connection means and a blender blade means secured to the lower end of the shaft and extending outwardly from the shaft to vigorously blend and mix liquids and solids in the container when rotated at a high rate of speed by the motor drive means.
