ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electric hand-held kitchen appliance, adapted to drive at least one working tool, comprising a housing enclosing an electric motor whose output shaft is adapted to drive the working tool having an axle of which one end is inserted in an opening provided in the housing, a speed control switch for the motor which is actuated by a manually operable button rotatably mounted along an axis of rotation so as to be able to occupy a “stop” position or several angularly offset “operating” positions, and a device for ejecting the working tool which is controllable by the button in the “stop” position.
It is particularly applicable, but not exclusively, to an electric hand-held beater adapted to drive at least one whisk or at least one kneader.
BACKGROUND OF THE INVENTION
In known electric kitchen appliances of this type, such as a hand-held beater, the manually actuated rotatable button is adapted, in addition to control the switch to regulate the speed of the motor, to control the ejector device for the whisks by means of a control mechanism, of the lever and cam type, and, to this end, is turned by the user beyond its “stop” position to control the actuation of the ejection device by the whisks. However, the ejection of the whisks being carried out in the same direction of movement of rotation of the button which permits control of the speed of the motor, it can be involuntarily used by the user when the latter turns the button in an untimely manner. Moreover, the manually operated rotatable button has a high angular swing to carry out both the control of speed of the motor and the control of ejection of the whisks, and as a result occupies a relatively large volume in the apparatus.
SUMMARY OF THE INVENTION
The invention has particularly for its object to overcome these drawbacks and to provide a hand-held electric kitchen appliance, of the type described above, in which the ejection of the working tool can be carried out easily and with precision in even the same stopped position of the manually-operated button.
According to the invention, the manually operated button is also swingably mounted about an axis transverse to its axis of rotation so as to control the actuation of the working tool ejector device.
Thus, the fact that the ejection of the working tool is carried out by a swinging movement of the button which is thus different from the rotation button of the latter, permits control of the speed of the motor, and requires on the part of the user a voluntary action on the button, which action is moreover particularly easy. Moreover, because of its double rotative and swinging movement, the manipulating button operates a reduced space in the apparatus.
According to another important characteristic of the invention, the manually operable button comprises a lug which directly actuates the ejector device for the working tool during swinging of the button. This direct actuation lug therefore constitutes a simple mechanical means, contrary to the complicated cam and lever mechanism according to the prior art, thus leading to less costly production of the manually operable button.
