`BACKGROUND OF THE INVENTION
`
`1. Ficld of the Invention
`
`The present invention relates to a cooker which uses
`induction heating to heat a pot for cooking by sautcing or
`other means.
`
`2. Description of the Prior Art
`Progress in technology which uses induction heating to
`heat magnetic pots has led to the recent development of
`rotary cookers which use induction heating to heat rotary
`pots for automatic sauteing. An electromagnetic cooker
`disclosed in the Japanese Patent Application Laid-Open
`No.63-175375 is such an example, and FIG. 33 shows a
`partial cross-section of the side of‘ the cooker.
`In the FIG. 33, receptacle 2 is mounted on top of main unit
`1, which has a built—in heating power supply, by hinge 3 so
`that it can rotate freely, and supported and fixed by support
`member 4 at a desired inclination angle. Support member 4
`consists of first support lever 4b and second support lever 4c
`which are joined together by pin 44:, and supports and fixes
`receptacle 2 at a desired angle by tightening pin 41:. Pot 7 is
`located at the central part of receptacle 2 in such a way that
`it can be rotated on axis 9 by driving unit 8 at the bottom.
`induction heating coil 6 is wired around pot 7 via heat
`insulator 5. Lid 10 is screwed onto the top of receptacle 2
`and slip ring 11 is provided between lid 10 and pot 7 to
`prevent ingredients inside pot 7 from escaping from recep-
`tacle 2. In addition, there is small lid 12 on the central top
`of the lid for inserting seasonings. Numbers 13 and 14 are
`control units for rotation speed and heating temperature or
`time. respectively, and 15 is ingredients.
`
`As an example to saute ingredients, using the cooker
`described above, incline receptacle 2 at a desired angle by
`support member 4 and turn on induction heating coil 6 to
`heat the outside of pot 7 while actuating driving unit 8 to
`rotate put 7. Then. put oil into pot 7 and stop the rotation
`when oil spreads all over put 7. Put ingredients 15 to be
`sauteed into the pot, cover with lid 10 and rotate put 7. Then,
`ingredients 15 are heated. stirred and sauteed within pot 7.
`At a proper time, open small lid 12 to add seasonings and
`cooking is over.
`The conventional electromagnetic cooker is configured
`and used as described above.
`
`(a) However, since receptacle 2 of the above electromag-
`netic cookcr is inclined manually, it is not easy to use. There
`is a risk of users’ getting burnt especially when changing the
`inclination angle of the receptacle during operation,
`(b) The pot for holding ingredients is heated by induction
`heating coil 6. However, heating coil 6 consists of only one
`layer, thus providing only a single cooking pattern. There-
`fore, the cooker can do only sautéing, and is thus limited in
`its application range.
`(c) The types of cooking possible with this cooker is
`limited.
`
`(:1) In addition, its heating method is very simple, cooking
`methods and heating times are limited. resulting in a narrow
`application range.

`(e) As the rotation speed of the pot is fixed and does not
`change during cooking, it has been diflicult to enhance the
`sauteing performance.
`([3 Induction heating coil 6 is wired between the side and
`the bottom of cooking pot 7 via heat insulator 5 to heat
`ingredients 15 inside the pot from the outside. Therefore,
`when cooking pot 7 is inclined, the top of cooking pot 7
`where there are no ingredients is also heated, resulting in a
`waste of electricity as well as a large size, complex structure
`and high production cost for induction heating coil 6.
`(g) Furthermore, since cooking pot 7 is rotated at a fixed
`speed and heated uniformly, ingredients 15 do not contact all
`parts of cooking pot 7, thus take a long time to cook. In
`addition, induction heating coil 6 is wired between the side
`and the bottom of cooking put 7 via heat insulator 5 to heat
`ingredients 15 from the outside. Therefore. when cooking
`put 7 is inclined, the top of cooking pot where there are no
`ingredients 15 is heated, resulting in a waste of electricity,
`and a large size, complex structure and high production cost
`for induction heating coil 6.
`(ti) Cooking pot 7 fixed on the tip of rotary axis 9 is
`rotated by actuating driving unit 8. Flange 7a of cooking pot
`7 is rotated while in contact with slip ring 11 fixed on
`stationary lid 10 to seal up the pot. Therefore, too light a
`sealing results in increased friction. the wearing of contact
`surfaces, and the generation of a gap which hinders the
`rotation of cooking pot 7. On the other hand, too loose a
`sealing results in soup running out from the gap to the inside
`of receptacle 2. Since cooking pot 7 is fixed, it is diilicult to
`clean after cooking and, accordingly, it becomes easily dirty.
`(i) when ingredients are to be sauteed, for instance, users
`must feel
`the temperature of the pot from the ambient
`temperature by putting their hands into cooking pot
`'7.
`Therefore, there is a risk of their getting burnt when they put
`their hands into the pot. Since the temperature of the cooking
`pot is unknown during cooking, heating temperature is
`controlled by the perception and experience of users. As a
`result, they carutot go away from the rotary cooker during
`cooking. If they go away from the cooker, the temperature
`of the cooking pot goes too high, resulting in scorching and
`an eventual danger of fire. In addition, when the cooking pot
`is heated continuously without
`ingredients
`inside,
`it
`becomes too hot and damages the receptacle.
`0) Cooking using the electromagnetic cooker is carried
`out as described above. Since the cooking temperature is
`unknown, the tinting for adding oil and seasonings and the
`tinting for taking out sauteed food rely on the perception and
`experience of cooks. In addition, if cooks go away from the
`cooker during cooking, ingredients are scorched and there is
`a danger of fire.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENT
`
`FIG. 1 shows a partial cross—section of the side and FIG.
`2 a partial cross-section of the front of a cooker according to
`the first embodiment.
`
`Numbers I to 7 in the figure refer to the same or
`equivalent parts as those of conventional cookers. Number
`20 is a support, 21 driving motor, 22 first gear, 23 second
`gear, 24 their axis, 25 bracket, 26 brake, 27.9 and b limit
`switches, 28 control circuit and 29 operation switch.
`As shown in the figure, ingredients are placed inside pot
`7 of the rotary cooker and cooked by rotating pot 7 with a
`rotating unit (not shown in the figure), heating it with
`induction heating coils 6 and inclining receptacle 2, when
`necessary.
`
`In the above rotary cooker according to the invention. a
`receptacle inclining unit consists of an inclination angle
`control unit, an inclination angle retention unit artd a con-
`troller. The inclination angle control unit is furnished with
`driving motor 21 fixed on support 2|], first gear 22 coupled
`with the axis of motor 21 and second gear 23 engaged with
`the first gear. Bracket 25 fixed at the bottom of receptacle 2
`is fitted with second gear 23 and can rotate freely on axis 24
`supported by support 20. Therefore, when driving motor 21
`is started, bracket 25 fixed on second gear 23 rotates at the
`same time as first gear 22 and second gear 23 engaged with
`the first gear rotate. receptacle 2 fixed on bracket 25 is
`accordingly inclined around axis 24. That is, receptacle 2 is
`Page 35 of 45
`Page 35 of 45
`
`

`
`5,512,733
`
`7
`inclined by the starting of motor 21. In addition, the angle
`retention unit can incline receptacle 2 at a desired angle by
`starting brake 26 when the inclination angle reaches a
`desired angle, and maintain the desired angle. To incline and
`maintain receptacle 2 at a desired angle of inclination,
`controller 28 is actuated by the operation of switch 29.
`Therefore,
`the inclination angle of receptacle 2 cart be
`changed during cooking. As shown in FIG. 2, the inclination
`angle of receptacle 2 can be selected freely between hori-
`zontal position a of pot 7 and position d when receptacle 2
`contacts the bottom of main unit 1. For this purpose, main
`unit. 1 is furnished with limit switches 27:: and 2712 so that
`when receptacle 2 touches limit switch 27:: or 27b at
`horizontal position a and maximum inclined position d,
`motor 21 stops operation. FIG. 3 shows the control circuit of
`the controller for the above operation.
`In this embodiment, the angle control unit uses gears. but
`ball screws, links and earns can be used instead of gears to
`control the angle of inclination.
`Since the cooker according to the present invention incor-
`porates a receptacle inclining unit which consists of an angle
`control unit for inclining a receptacle at a desired angle, an
`angle retention unit for keeping the receptacle inclined at the
`desired angle and a controller, it allows the receptacle to be
`freely inclined through switch operation during cooker
`operation, thus greatly improving the operational ease of the
`cooker.
`
`FIG. 4 is a diagram showing a cross~section of the
`receptacle of a cooker according to the second embodiment.
`In the figure, number 7 is a pot, 220 first coil, 221 second
`coil, 222 first coil input controller, 223 second coil input
`controller, and 224 input switch. The cooker incorporates an
`angle control unit and a controller described in FIG. 33.
`In the figure, a pot rotation driving unit and a receptacle
`inclining unit are omitted.
`As shown in the figure, heating coils consist of the first
`coil for heating the bottom of the pot and the second coil for
`heating the side of the pot. Input switch 24 is used to turn on
`the first or second coil only or both of them.
`As a result, only the first coil is used for roasting meat,
`while only the second coil is used for preparing curry and
`stew. For sauteing vegetables and noodles, it is recom-
`mended to use both of these coils.
`
`In this way, the cooker can change heating methods
`according to type of cooking, resulting in an increased types
`of meals to be prepared by this rotary cooker, expanded
`application range and improved operational ease of the
`cooker.
`
`According to the present invention, the rotary cooker
`incorporates heating means which consist of the first coil for
`heating the pot bottom and the second coil for heating the
`pot side to heat the pot by using either one of them or both
`of them, thus greatly increasing the types of meals to be
`prepared by this rotary cooker and improving its operational
`ease.

`Furthermore, rotation driving unit 18 described above
`consists of driving motor 18:: and driving wheels 18!), and
`heating coils are installed inside housing 115. Inclining unit
`120 is comprised of driving motor 21 fixed to support 20,
`first gear 22 coupled with the axis of motor 2] and second
`gear 23 engaged with first gear 22. Bracket 25 fixed to the
`bottom of housing 115 is mated with axis 24 so that it can
`rotate freely. Axis 24 fitted with second gear 23 is fixed to
`support 20. Therefore, the actuation of motor 21 rotates
`gears 22 and 23 and bracket 25 simultaneously to incline
`receptacle 2. In addition, angle detection unit 127 for
`detecting the angle of receptacle 2 inclined by inclining unit
`120 described above consists of infrared transmission unit
`128 fixed on support 25 and several flag plates 29:: to d
`mounted on bracket 25. Each time flag plates 129 n to d fixed
