Definitions

  • the present invention relates to a heating cooker using a halogen lamp.
  • a heating cooker using halogen lamp is well known. Since this heating cooker utilizes electricity and, so, no flame and smoke are produced, it is safe. Since it heats a pan or flying pan directly, it is efficient. Further, it is clean and easily cleaned due to its soot-free nature and has, in addition to an advantage of a heater type cooker that a temperature can be regulated in stepless manner, an advantage of short rising time which can not be obtained with heaters of other types.
  • a configulation of a bottom portion of almost all of cooking devices is circular and, therefore, a heating portion of a heating cooker should be in the ring form in view of thermal efficiency.
  • a heating portion of a heating cooker should be in the ring form in view of thermal efficiency.
  • a conventional heating cooker utilizes a plurality of straight halogen lamps arranged in parallel and a circular window portion is formed by a masking plate disposed on a cooking plate.
  • An object of the present invention is to solve the problems of the conventional cooker mentioned above and to provide a long life heating cooker which utilizes an annular halogen lamp.
  • Another object of the present invention is to provide a heating cooker in which a light emissive portion of a halogen lamp can be made substantially annular.
  • the present invention which achieves the above object resides, in a heating cooker having a halogen lamp provided beneath a cooking plate as a heat source and a reflective member surrounding an outer side of the halogen lamp, in that an intermedial portion of the halogen lamp is bent so that opposite end portions thereof are crossed to form a substantially circular, annular portion and that sealing portions at the opposite end portions of the halogen lamp are positioned outside the reflective member.
  • the present invention which achieve the another object resides in that the halogen lamp is crossed within the reflective member and that the light emissive portion is provided in an area covering from the crossing position to the side of the annular portion.
  • Figs. 1 and 2 show only main portions of an embodiment of a heating cooker according to the present invention for better understanding thereof.
  • a reference numeral 1 depicts a cooking plate of heat resistive glass or the like, 2 a halogen lamp and 3 a reflective member constituted as a reflective plate surrounding an outside of the halogen lamp 2.
  • the halogen lamp 2 has an intermedial portion bent to form a substantial circular configulation as shown in Figs. 1 and 3, with opposite end portions thereof which are straight being crossed and extended outwardly of the reflective plate 3. That is, the halogen lamp 2 forms an annualar portion 4 by crossing its opposite end portions and sealing portions 5 at the respective end portions are positioned outside the reflective plate 3.
  • the crossing portions of the halogen lamp 2 are within the reflective plate 3 and a filament which is a light emissive portion of the halogen lamp 2 is provided in the annular portion 4 formed between crossing end portions. Further, in this case, a notch 3a is formed in the reflective plate 3, through which the opposite end portions of the halogen lamp extend outwardly.
  • a reference numeral 10 depicts a sensor for sensing temperature of a reagion near a surface of the cooking plate 1.
  • thermoelectric heating cooker which utilizes a substantially annular halogen lamp whose sealing portions are arranged within a reflection plate
  • temperature around a surface of the halogen lamp within the reflection plate in which radiation of the halogen lamp also attributes a heating becomes as high as about 700°C - 800°C.
  • a light emmisive portion of the halogen lamp becoms circular having a portion removed, that is, substantially C-shaped, resulting in no annular configulation.
  • Figs. 4 and 5 are a disassembled perspective view and a cross sectional view of another embodiment of the present invention, respectively.
  • a cooking plate 1 comprises a ultra heat resistive glass ceramic plate 11 and a masking plate 12 and is fixed in a casing 13 of the cooker.
  • a reflection plate 3 comprises a cylindrical side wall 14, a center land portion 15, a pair of support arms 16 extending from the center land portion 15 to the side wall 14 and a bottom plate 17, all of which are formed of a heat insulating material, integrally as a unit.
  • the reflection plate 3 is formed by molding of ceramic firber material.
  • a temperature sensor 10 is provided in the center land portion 15.
  • the side wall 14 is formed with a notch portion 18 and a halogen lamp 2 is. supported by the notch portion 18 and receiving grooves 19 formed in the respective support arms 16.
  • the notch portion 18 is fitted with a joint piece 20 by which opposite end portions of the halogen lamp 2 are fixedly supported such that they penetrate the side wall 14 with substantially no gap therebetween.
  • a circular heat insulating plate 21 is attached to a lower surface of the reflection plate 3 and is formed of a heat insulating material (tradename "MicroTherm”) which has a ultra fine porous structure and contains mainly ultra fine silica particles, ceramic fibers and devitrifying agent.
  • An assembly of the reflection plate 3 and the heat insulating plate 21 is received in a dish shaped receiving member 22 which is supported by a bottom cover 24 through a compression spring 23. With this compression spring 23, an upper surface of the reflection plate 3 is urged against the cooking plate 1 and, since the halogen lamp 2 penetrates the side wall 14 with substantially no gap therebetween, an interior of the reflection plate 3 is kept air-tightly.
  • the side portion and the bottom portion of the reflection plate 3 of the heating cooker constructed-in this manner are of the heat insulating material and kept air-tightly, heat generated by the halogen lamp 2 is substantially used to heat the cooking plate 1, resulting in further improved heat efficiency. Further, since substantial heat leakage outwardly of the reflection plate 3 becomes hard to occur, the sealing portions 5 of the halogen lamp 2 can be maintained at relatively low temperature, resulting in no need of air cooling means.
