Abstract

A working container for electrical household food preparation appliances including a lower transmission component connected by a shaft to a rotary working tool arranged in a receptacle, wherein the shaft runs through the bottom of the receptacle and is rotatably mounted in a bearing housed in the bottom of the receptacle by virtue of the lower transmission component having an upper flange ring forming a reservoir around the shaft. The inner wall of the flange ring enables the collection of oil coming from the bearing and prevents the projection of oil onto a wall of the working container and permits the oil to drain to the bottom of the reservoir.

First claim

The invention claimed is:

1. A working container for electrical household food preparation appliances comprising:
a receptacle having a rotary working tool arranged in the receptacle;
a shaft having a first end and a second end, the first end of the shaft being connected to the rotary working tool and the second end extending through a bottom of the receptacle;
a bearing having a first end and a second end, the bearing being arranged in the bottom of the receptacle for rotatably supporting the shaft; and
a lower transmission component connected by the second end of the shaft to drive the rotary working tool via a lower drive unit, the lower transmission component has an having a body with an annular upper flange ring defining a recessed reservoir between a sidewall of the upper flange ring and the second end of the shaft,
wherein the second end of the bearing is arranged in the reservoir.

2. The working container as in claim 1 , wherein the bearing is housed in a pipe.

3. The working container as in claim 2 , wherein the pipe has a lower end surrounding a lower portion of the bearing, the lower end of the pipe extending into the reservoir.

4. The working container as in claim 1 , wherein the bearing is made of a sintered metal material.

5. The working container as in claim 1 , wherein the bearing rests on a washer.

6. The working container as in claim 1 , wherein a seal is mounted on the shaft between the bearing and the rotary working tool.

7. The working container as in claim 6 , wherein the seal is a lip seal.

8. The working container as in claim 1 , wherein the reservoir has a channel.

9. The working container as in claim 8 , wherein the upper flange ring is arranged around a periphery of the channel.

10. The working container as in claim 1 , wherein the lower transmission component has outer fins.

11. The working container as in claim 10 , wherein the outer fins are arranged around a periphery of the upper flange ring.

12. An electrical household food preparation appliance comprising a base housing a motor associated with an upper driver unit, and a working container comprising a lower transmission component connected by a shaft to a rotary working tool arranged in a receptacle, the shaft running through a bottom of the receptacle and being rotatably mounted in a bearing housed in the bottom of the receptacle, the lower transmission component being rotatably driven by the upper driver unit when the working container is disposed on the base, wherein the working container is configured according to claim 1 .

13. The electrical household food preparation appliance as in claim 12 , wherein the upper driver unit is directly driven by the motor.

14. The electrical household food preparation appliance as in claim 12 , wherein the rotary working tool is rotatably driven at a speed greater than 5000 rpm.

15. A working container for electrical household food preparation appliances comprising:
a receptacle having a rotary working tool arranged in the receptacle;
a shaft having a first end and a second end, the first end of the shaft being connected to the rotary working tool and the second end extending through a bottom of the receptacle;
a bearing having a first end and a second end, the bearing being arranged in a pipe at the bottom of the receptacle for rotatably supporting the shaft; and
a lower transmission component connected by the second end of the shaft to drive the rotary working tool via a lower drive unit, the lower transmission component having a body with an annular upper flange ring defining a recessed reservoir between a sidewall of the upper flange ring and the second end of the shaft,
wherein the pipe has a lower end surrounding a lower portion of the bearing, the lower end of the pipe extending into the reservoir.

16. The working container as in claim 15 , wherein the bearing is made of a sintered metal material.

17. The working container as in claim 15 , wherein the bearing rests on a washer.

18. The working container as in claim 15 , wherein a seal is mounted on the shaft between the bearing and the rotary working tool.

19. The working container as in claim 18 , wherein the seal is a lip seal.

20. The working container as in claim 15 , wherein the reservoir has a channel.

21. The working container as in claim 20 , wherein the upper flange ring is arranged around a periphery of the channel.

22. The working container as in claim 15 , wherein the lower transmission component has outer fins.

23. The working container as in claim 22 , wherein the outer fins are arranged around a periphery of the upper flange ring.

24. An electrical household food preparation appliance comprising a base housing a motor associated with an upper driver unit, and a working container comprising a lower transmission component connected by a shaft to a rotary working tool arranged in a receptacle, the shaft running through a bottom of the receptacle and being rotatably mounted in a bearing housed in the bottom of the receptacle, the lower transmission component being rotatably driven by the upper driver unit when the working container is disposed on the base, wherein the working container is configured according to claim 15 .

25. The electrical household food preparation appliance as in claim 24 , wherein the upper driver unit is directly driven by the motor.

26. The electrical household food preparation appliance as in claim 24 , wherein the rotary working tool is rotatably driven at a speed greater than 5000 rpm.
