Abstract
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 adjusting arrangement is intended for facilitating the use of the electronic oven without substantially requiring any experience in handling the oven itself.

Total Claims: 12
Claim 1
Independent Claim
322 words
A cooking time selection and adjusting arrangement for use in an electronic oven of the type including an oven-defining structure having an access opening, means positioned for generating high frequency energy toward the interior of said oven-defining structure, and a hingedly supported door covering said access opening of said oven-defining structure, said time selection and adjusting arrangement comprising: an instrument panel mounted on said oven-defining structure, said instrument panel having a front surface with a window portion and an aperture therein; a pair of rolls rotatably mounted one above the other within said instrument panel; a belt member having a length greater than the spacing between said rolls, said belt member having opposite ends wound around and connected to said rolls, said belt member having a front surface visible through said window portion of said instrument panel, said front surface of said belt member having thereon data relating to cooking menus and cooking times corresponding thereto; driving means coupled to at least one of said rolls for synchronously rotating said rolls in the same direction, to thereby place selected of said menu and corresponding cooking time data on said belt member in a position to be viewed through said window portion; a timer device mounted in said instrument panel and having an operating shaft extending through said aperture in said instrument panel, said timer device being operatively coupled to said means for generating high frequency energy, whereby an operator may set said timer device to a cooking time of a selected menu visible through said window portion, and operation and stopping of said timer device start and stop said means for generating high frequency energy; and a movable pointer needle mounted on said instrument panel and operatively coupled to said operating shaft to be moved thereby along said window portion and indicate the operating time of said means for generating high frequency energy corresponding to said cooking time of said selected menu.

322 words
A cooking time selection and adjusting arrangement for use in an electronic oven of the type including an oven-defining structure having an access opening, means positioned for generating high frequency energy toward the interior of said oven-defining structure, and a hingedly supported door covering said access opening of said oven-defining structure, said time selection and adjusting arrangement comprising: an instrument panel mounted on said oven-defining structure, said instrument panel having a front surface with a window portion and an aperture therein; a pair of rolls rotatably mounted one above the other within said instrument panel; a belt member having a length greater than the spacing between said rolls, said belt member having opposite ends wound around and connected to said rolls, said belt member having a front surface visible through said window portion of said instrument panel, said front surface of said belt member having thereon data relating to cooking menus and cooking times corresponding thereto; driving means coupled to at least one of said rolls for synchronously rotating said rolls in the same direction, to thereby place selected of said menu and corresponding cooking time data on said belt member in a position to be viewed through said window portion; a timer device mounted in said instrument panel and having an operating shaft extending through said aperture in said instrument panel, said timer device being operatively coupled to said means for generating high frequency energy, whereby an operator may set said timer device to a cooking time of a selected menu visible through said window portion, and operation and stopping of said timer device start and stop said means for generating high frequency energy; and a movable pointer needle mounted on said instrument panel and operatively coupled to said operating shaft to be moved thereby along said window portion and indicate the operating time of said means for generating high frequency energy corresponding to said cooking time of said selected menu.
Claim 3
Dependent Claim
28 words
A time selection and adjusting arrangement as claimed in claim 1, further comprising cleaning device means mounted within said instrument panel for contacting and cleaning said belt member.
Claim 4
Dependent Claim
24 words
A time selection and adjusting arrangement as claimed in claim 1, further comprising a protective film covering said front surface of said belt member.
Claim 5
Dependent Claim
46 words
A time selection and adjusting arrangement as claimed in claim 1, wherein said belt member is made of transparent synthetic material; and further comprising electric light illuminating means, mounted in said instrument panel behind said belt member, for illuminating said belt member and said oven-defining structure.
Claim 6
Dependent Claim
41 words
A time selection and adjusting arrangement as claimed in claim 1, further comprising cable means operatively coupling said pointer needle to said operating shaft for moving said pointer needle along said window portion in response to rotation of said operating shaft.
Claim 7
Dependent Claim
61 words
A time selection and adjusting arrangement as claimed in claim 5, wherein said cable means has opposite ends thereby connected by a tension spring, and further comprising a pair of projection means on said instrument panel and extending within the stroke of movement of said tension spring for facilitating connection of said tension spring between said ends of said cable means.
Claim 8
Dependent Claim
95 words
A time selection and adjusting arrangement as claimed in claim 5, further comprising a drive wheel mounted on said operating shaft and a plurality of idle pulleys mounted on said instrument panel, said cable means being suspended around said drive wheel and idle pulleys, two of said idle pulleys being positioned on both sides of said drive wheel such that a first portion of said cable means entering said drive wheel and a second portion of said cable means energing from said drive wheel are aligned in a straight line with respect to each other.
Claim 9
Dependent Claim
35 words
A time selection and adjusting arrangement as claimed in claim 7, wherein said two idle pulleys are rotatably suported at positions respectively frontwardly and backwardly displaced with respect to the plane of said drive wheel.
Claim 10
Dependent Claim
56 words
A time selection and adjusting arrangement as claimed in claim 7, further comprising a guide rail on said instrument panel, a block slidably mounted on said guide rail, and means for securing said cable means to said slidable block at opposite ends thereof, said opposite ends projecting from said block in the direction of movement thereof.
Claim 11
Dependent Claim
67 words
A time selection and adjusting arrangement as claimed in claim 7, wherein said drive wheel has formed in one face thereof a hollow projection, the interior of said hollow projection being formed with a plurality of pairs of opposed protrusions for firmly securing a pin provided on said operating shaft, thereby permitting said drive wheel to be rigidly and firmly mounted in position on said operating shaft.
Claim 12
Dependent Claim
57 words
A time selection and adjusting arrangement as claimed in claim 7, wherein said drive wheel has formed on the periphery thereof a notch and a pair of projections on both sides of said notch, each of said projections projecting from the plane of said wheel in a direction parallel to the longitudinal axis of said operating shaft.
