Cooking time adjusting arrangement for use in electronic oven

Abstract

A cooking time adjusting arrangement for use in an electronic oven is disclosed. The arrangement includes a display device representing a plurality of data such as various menus, the number and/or quantity of each of the menus with or without cooking times, setting of a timer device to operate the electronic oven for a predetermined cooking time proper to a selected one of the menus being performed with reference to the reading of the display device. The cooking time adjustment arrangement is intended for facilitating the use of the electronic oven without substantially requiring any experience in handling the oven itself.

A cooking time adjusting arrangement as claimed in claim 1, wherein said display means comprises a pair of synchronously rotatably supported rolls spaced one above the other in equidistantly spaced relation with respect to each other, means for rotating said rolls in the same direction in synchronism with respect to each other, a belt wound around each of said rolls and having one front surface carrying said informations, said belt being shiftable upon rotation of any one of said rolls..]. .[.6. A cooking time adjusting arrangement as claimed in claim 5, further comprising a cleaning device for sweeping said belt to keep the latter clear..]. .[.7. A cooking time adjusting arrangement as claimed in claim 5, wherein said belt has said front surface applied with a protective film..]. .[.8. A cooking time adjusting arrangement as claimed in claim 5, wherein said belt is made of transparent synthetic material and further comprising an electrical light positioned backwards of said belt and above the ceiling of said oven-defining structure for illuminating said belt and the interior of said oven-defining structure..]..Iadd. 9. A cooking time adjusting arrangement as claimed in claim 1, wherein said rotatable drum is biased in one direction by a compression spring mounted on a shaft of said drum. .Iaddend..Iadd. 10. A cooking time adjusting arrangement as claimed in claim 1, wherein said drum is made of transparent material and further comprising an electrical lamp for illuminating said drum, said lamp being housed within said drum. .Iaddend..Iadd. 11. A cooking time adjusting arrangement as claimed in claim 10, wherein said drum is rotatably supported by a socket for supplying a power therethrough to said lamp. .Iaddend. .Iadd. 12. A cooking time adjusting arrangement as claimed in claim 10, wherein said lamp is operatively positioned to project rays of light to the peripheral rim of said drum. .Iaddend..Iadd. 13. A cooking time adjusting arrangement as claimed in claim 1, further comprising an electrical lamp for lighting said drum, said lamp being disposed between said instrument panel and said drum, said instrument panel being removable from the body of the electronic oven. .Iaddend..Iadd. 14. A cooking time adjusting arrangement as claimed in claim 1, wherein said drum is covered by a covering having an opening in register with said window portion and further comprising an electrical lamp positioned behind said drum for illuminating said drum, rays of light emitted from said lamp being transmitted to said opening by being reflected by the inner surface of said covering. .Iaddend..Iadd. 15. The device of claim 1 wherein said rotatable drum is coupled to said operating shaft and driven thereby synchronously with said pointer needle, information being arranged on said drum in numerical order according to required cooking times whereby said pointer will be appropriately positioned for the information displayed. .Iaddend..Iadd. 16. A cooking time adjusting arrangement as claimed in claim 1, wherein said pointer needle is coupled to said operating shaft by a cable and moves in response to rotation of said operating shaft, said pointer needle moving in parallel relation to the longitudinal axis of said drum along said window. .Iaddend. .Iadd. 17. A cooking time adjusting arrangement as claimed in claim 16, wherein a drive wheel mounted on said operating shaft and a plurality of idle pulleys, two of said idle pulleys being positioned on opposite sides of said drive wheel are provided such that a first portion of said cable entering said drive wheel and a second portion of said cable emerging from said drive wheel are aligned in a straight line with respect to each other. .Iaddend..Iadd. 18. A cooking time adjusting arrangement as claimed in claim 17, wherein said two of said idle pulleys are rotatably supported by a fixed member such that said two pulleys are respectively frontwardly and rearwardly displaced with respect to the plane of said drive wheel. .Iaddend..Iadd. 19. A cooking time adjusting arrangement as claimed in claim 16, wherein said pointer needle is connected with said cable by means of a block slidably mounted on a guide rail, said block having a member for securing said cable to said block at both ends thereof, both ends thereof projecting from said block in the direction of movement of said slidable block. .Iaddend..Iadd. 20. A cooking time adjusting arrangement as claimed in claim 16, wherein said cable has both ends connected by means of a tension spring and further including a pair of projections extending from a fixed member within the stroke of movement of said tension spring for facilitating connection between said ends of said cable by means of said tension spring. .Iaddend..Iadd. 21.
