Claims
- 1. A food processor, comprising:a housing; different tools adapted to be placed at said housing; an electric motor drive coupled to one of said tools when said one tool is placed at said housing; and a switching element actuated in two switching directions, at least one of said two switching directions being blocked as a function of a given one of said tools placed at said housing.
- 2. The food processor according to claim 1, wherein:a part is coupled in a rotationally fixed manner to said switching element, said part has a circumference and at least one blocking element disposed on said circumference; a counter-blocking element is selectively coupled to at least one of said tools when said at least one tool is placed at said housing; and said at least one blocking element blocks rotation of said switching element in one of said two switching directions.
- 3. The food processor according to claim 2, wherein:said at least one blocking element has an adjustment path; said counter-blocking element is a strip-shaped projection; and each of said tools has said strip-shaped projection projecting into said adjustment path of said at least one blocking element when said tools are respectively placed at said housing.
- 4. The food processor according to claim 2, wherein:said part is a connecting disk; said at least one blocking element is a radially outward-projecting blocking tongue; and said counter-blocking element is a pushrod actuated dependent upon a respective one of said tools being placed in a position to project said pushrod into said adjustment path of said blocking tongue.
- 5. The food processor according to claim 4, wherein:said pushrod is displaceable in a blocking direction; a spring holds said pushrod in a rest position; at least one of said tools has an actuating finger; and said pushrod is adjusted in said blocking direction by said actuating finger when said at least one tool is placed at said housing.
- 6. The food processor according to claim 2, wherein:said at least one blocking element is a first blocking element and a second blocking element; said first blocking element blocks rotation of said switching element in a first of said two switching directions; and said second blocking element blocks rotation of said switching element in a second of said two switching directions.
- 7. The food processor according to claim 1, wherein said switching element is a momentary switch at least in one of said two switching directions.
- 8. The food processor according to claim 4, wherein:said housing has a latching tongue fixedly disposed thereon; latching recesses are disposed on said circumference of said connecting disk at least for one of said two switching directions; and said latching tongue engages at least one of said latching recesses.
- 9. The food processor according to claim 4, wherein:said housing has a latching tongue; latching recesses are disposed on said circumference of said connecting disk; and said latching tongue engages at least one of said latching recesses at least when said switching element is switched in one of said two switching directions.
- 10. In a food processor having a housing and an electric motor drive, a switching assembly comprising:different tools adapted to be placed on the housing and coupled to the electric motor drive when one of said tools is placed on said housing; and a switching element actuated in two directions, at least one of said two directions being blocked as a function of a given one of said tools placed on the housing.
- 11. The food processor according to claim 10, wherein:a part is coupled in a rotationally fixed manner to said switching element, said part has a circumference and at least one blocking element disposed on said circumference; a counter-blocking element is selectively coupled to at least one of said tools when said at least one tool is placed at the housing; and said at least one blocking element blocks rotation of said switching element in one of said two switching directions.
- 12. The food processor according to claim 11, wherein:said at least one blocking element has an adjustment path; said counter-blocking element is a strip-shaped projection; and each of said tools has said strip-shaped projection projecting into said adjustment path of said at least one blocking element when said tools are respectively placed at the housing.
- 13. The food processor according to claim 11, wherein:said part is a connecting disk; said at least one blocking element is a radially outward-projecting blocking tongue; and said counter-blocking element is a pushrod actuated dependent upon a respective one of said tools being placed in a position to project said pushrod into said adjustment path of said blocking tongue.
- 14. The food processor according to claim 13, wherein:said pushrod is displaceable in a blocking direction; a spring holds said pushrod in a rest position; at least one of said tools has an actuating finger; and said pushrod is adjusted in said blocking direction by said actuating finger when said at least one tool is placed at the housing.
- 15. The food processor according to claim 11, wherein:said at least one blocking element is a first blocking element and a second blocking element; said first blocking element blocks rotation of said switching element in a first of said two switching directions; and said second blocking element blocks rotation of said switching element in a second of said two switching directions.
- 16. The food processor according to claim 10, wherein said switching element is a momentary switch at least in one of said two switching directions.
- 17. The food processor according to claim 13, wherein:the housing has a latching tongue fixedly disposed thereon; latching recesses are disposed on said circumference of said connecting disk at least for one of said two switching directions; and at least one of said latching recesses is adapted to engage the latching tongue.
- 18. The food processor according to claim 13, wherein:the housing has a latching tongue; latching recesses are disposed on said circumference of said connecting disk; and at least one of said latching recesses is adapted to engage the latching tongue at least when said switching element is switched in one of said two switching directions.
