Abstract

A household mixer appliance having an open top mixing container, a hook and a drive arrangement. The mixing container has a side wall portion with a through hole for the drive arrangement and the hook is arranged to be rotatable around an axis of rotation within the mixing container via the drive arrangement. A seal is arranged between the drive arrangement and the side wall portion of the mixing container, and the drive arrangement includes a quick-release mechanism to which the hook is attachable.

Claims

1. A household mixer appliance comprising:

a hook;

a drive arrangement operatively connectable to the hook and, when connected to the hook, configured to rotate the hook around an axis of rotation within an open top mixing container, wherein the mixing container comprises a side wall portion having a through hole for the drive arrangement; and

a seal arranged between the drive arrangement and the side wall portion of the mixing container, wherein the seal is fitted in the through hole between the side wall portion of the mixing container and the drive arrangement;

wherein the drive arrangement comprises a bayonet coupling arrangement as a quick-release mechanism to which the hook is attached.

2. The household mixer appliance according to claim 1, wherein the hook comprises:

a distal end; and

a proximal end provided with a sole attachment portion that is arranged to be attachable to the quick-release mechanism of the drive arrangement.

3. The household mixer appliance according claim 1, wherein the axis of rotation is substantially horizontal.

4. The household mixer appliance according to claim 1, wherein the drive arrangement comprises a first coupling member that is at least partly arranged to extend into the through hole of the mixing container.

5. The household mixer appliance according to claim 4, wherein the hook is attachable to the first coupling member via the quick-release mechanism.

6. The household mixer appliance according to claim 4, wherein the hook and the mixing container are detachable from the drive arrangement when the hook is detached from the quick-release mechanism.

7. The household mixer appliance according to claim 4 wherein the first coupling member comprises a flange, and where the seal is arranged radially outwards of the flange, towards a cylindrical surface that forms the through hole.

8. The household mixer appliance according to claim 4, wherein the seal and the first coupling member together are arranged to seal off the through hole when the hook is attached to the drive arrangement.

9. The household mixer appliance according to claim 4, wherein the drive arrangement comprises a second coupling member that is arranged to transfer rotational movement from an electric motor to the hook via the first coupling member.

10. The household mixer appliance according to claim 9, wherein the hook, the quick-release mechanism, the mixing container, the seal and the first coupling member together form an assembly that is detachable as one unit from the second coupling member.

11. A household mixer appliance comprising:

a hook;

a drive arrangement operatively connectable to the hook and, when connected to the hook, configured to rotate the hook around an axis of rotation within an open top mixing container, wherein the mixing container comprises a side wall portion having a through hole for the drive arrangement; and

a seal arranged between the drive arrangement and the side wall portion of the mixing container, wherein the seal is fitted in the through hole between the side wall portion of the mixing container and the drive arrangement;

wherein the drive arrangement comprises a snap-lock arrangement as a quick-release mechanism to which the hook is attached.
