发明名称 Operating means in a domestic appliance
摘要 <p>A domestic appliance (10, fig 1) eg. for cooking, has an operating means 13 rotatable about an axis 11 substantially parallel to a front face 12 of the appliance on which it is mounted. The means 13 may be ellipsoidal, and be carried on a shaft 20 in a removable mounting 19 which is detachable from a recess (28, fig 5) in the front face for cleaning. The mounting 19 is retained by detents engaging leaf springs 27, 27' and magnets (14, fig 3). Magnet tracks 22,23 and magnetic sensors (30,31, fig 5) produce a signal for incrementing or decrementing values in a computer (29, fig 2). The means 13 and push buttons (16,16', fig 5) are used to navigate menus on a display (17, fig 1) and to set values. Other embodiments of the contactless sensing have angularly and axially offset magnets (fig 7) or a spiral arrangement of iron cores 33 which vary inductance of a coil (34, fig 8). The means 13 may be a track ball or roller.</p>
