Abstract

A stand mixer 10 comprises a head unit 50 having a lower surface presenting, in operation, a downwardly-facing drive outlet for driving in rotation at least one tool suspended therefrom. The head unit is supported with the downwardly-facing drive outlet above a receiving location 30 for a mixing bowl 40. Driving means, including an electric motor 70 and associated transmission means for conveying rotary drive to the drive outlet, are provided. The mixer further comprises first 80 and second 90 coaxial driving outlets presented on an upper surface 52 of the head unit 50; the coaxial outlets 80, 90 run at different speeds and are driven from the motor 70 by means of an epicyclic gearbox 100. The motor 70 is housed in the support means 60 with its drive shaft 72 in substantial alignment with the coaxial drive outlets 80, 90.

First claim

What is claimed is:

1. A stand mixer comprising:
a head unit having a lower surface presenting, in operation, a downwardly- facing drive outlet for driving in rotation at least one tool suspended therefrom;
support means for supporting said head unit with said downwardly-facing drive outlet above a receiving location for a mixing bowl;
driving means including an electric motor having a drive shaft, and associated transmission means for conveying rotary drive to said downwardly-facing drive outlet, the motor being housed in said support means;
first and second coaxial driving outlets presented on an upper surface of said head unit, said first and second coaxial outlets running at different speeds; and
an epicyclic gearbox arranged to be driven by the motor, and arranged to drive the first and second coaxial drive outlets;
wherein the first coaxial drive outlet and a sun wheel of said epicyclic gearbox are driven at a relatively high speed by said motor, and
wherein the second coaxial drive outlet is driven at a lower speed than said first coaxial drive outlet from a planet carrier of said gearbox.

2. The mixer according to claim 1 , wherein said transmission means includes transfer means configured to convey, from said epicyclic gearbox to said downwardly-facing drive outlet, rotational drive at a substantially lower speed than said first and second coaxial drive outlets.

3. The mixer according to claim 1 , wherein, in use of the stand mixer, one or both of the first and second driving outlets and the downwardly-facing drive outlet operate simultaneously.

4. The mixer according to claim 1 , wherein the downwardly-facing drive outlet and the coaxial drive outlets are driven by the same motor and epicyclic gearbox arrangement.

5. The stand mixer according to claim 1 , in which the motor is housed in the support means.

6. The stand mixer according to claim 1 , wherein the downwardly-facing drive outlet is a planetary drive outlet.

7. The mixer according to claim 1 , further comprising means associated with said coaxial outlets for encouraging fluid spilt in the vicinity of said coaxial outlets to flow into a collection means, and further means adapted to conduct collected fluid out of the mixer; thereby impeding ingress of said fluid into said gearbox.

8. A kit comprising: a stand mixer according to claim 1 , a first attachment for coupling to a first drive outlet of the stand mixer; a second attachment for coupling to a second drive outlet of the stand mixer; and a tool for coupling to a downwardly-facing drive outlet of the stand mixer.

9. The kit according to claim 1 , wherein the first attachment comprises a blender attachment configured to be attached to the first driving outlet running at a higher speed such that blades of the blender attachment are driven directly by the first driving outlet.

10. The kit according to claim 1 , wherein the second attachment comprises a food processor having a processing tool, the processor being configured to be attached to the second driving outlet running at a lower speed such that the processing tool is driven directly by the second driving outlet.

11. The kit according to claim 10 , in which the food processor is a juicer.

12. The kit according to claim 1 , wherein the first and second attachments each comprise a drive coupling configured to transfer rotational drive form the first and second drive outlets through the base of the attachment to rotatable food processing tools mounted within the attachment.

13. The kit according to claim 1 , wherein the first and second attachments are each fitted with a closable lid having a safety interlock arranged to prevent the tools being driven unless the lid is closed.

14. The kit according to claim 8 , wherein the tool is a mixing tool.
