BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary cooking machine that automatically stirs and cooks cooking ingredients such as rice and vegetables by rotating a heated cooking pot while tilting it.

0002

[Prior Art] Conventional rotary cooking machines of this type include, for example, Utility Model Application No. 56-164717 and Japanese Patent Application Publication No. 63-1753.
The configurations of the two devices described in Publication No. 75 are shown in FIGS. 5 and 6.

In FIG. 5, 1 is a support, 2 is an inclined surface thereof, and 3 is an opening. 4 is a drive motor, 5 is a rotating shaft,
6 is a heating element. 8 is a magnet thermo, 13 is a cooking container, 14 is a flange, 15 is a thermal ferrite, 1
6 is an engaging portion, and 17 is a receiving portion. Further, 18 is a protrusion formed on the inner surface of the cooking container 13 for stirring the cooking ingredients.

[0004] This electric cooker has a cooking container 13 mounted on a support 1.
The receiving part 17 is inserted into the engagement part 1 of the drive motor 4 in an inclined manner.
6 to engage and connect. Then, the power switch is closed to cause the cooking container 13 to rotate in conjunction with the rotation of the drive motor 4, and to be heated by the heating element 6 disposed around its outer periphery. When the temperature of the cooking container 13 reaches the Curie temperature of the thermal ferrite 15, the magnet thermo 8 senses and operates.
The circuit is opened by separating the contacts of a switching mechanism (not shown). Further, the circuit closes when the temperature decreases, and the temperature is adjusted to be maintained around the Curie temperature, so that cooking can be carried out by rotating and stirring the cooking material in the cooking container 13 while heating it.

Further, in FIG. 6, 21 is the main body of the cooking device, 22 is a processing container, and 23 is a hinge. A support member 24 includes a pin 24a and first and second support levers 24b and 24c. 25 is a heat insulating member, 26 is an induction heating coil, 27 is a cooking pot, 28 is a driving means, and 29 is its rotating shaft. The driving means 28 is attached to the inner surface of the processing container 22, and a cooking pot 27 is fixed to the tip of a rotating shaft 29. Further, 30 is a lid body, 31 is a small lid, 32 is a flange of the cooking pot 27, and 33 is a slip ring. The lid 30 is screwed onto the top of the processing container 22, and a small lid 31 is further screwed onto the lid 30. 34 is a cooking material, and 35 and 36 are control units for controlling rotation speed, heating temperature, heating time, etc.

In the electromagnetic cooker shown in FIG. 6, the induction heating coil 2 is rotated through the driving means 28 to the cooking pot 27
6 is energized to heat its outer periphery. After heating the cooking pot 27, add oil. Cooking ingredients 34 are placed in the cooking pot 27 after the oil has evenly adhered to the inside of the cooking pot 27, and the top of the cooking pot 27 is quickly covered with a lid body 30. Subsequently, when the heating state of the cooking pot 27 is maintained and rotation is given by the driving means 28, the cooking material 34 begins to be fried in oil while being heated and stirred in the cooking pot 27. When the time is right, the small lid 31 is removed and seasonings are added, and if necessary, the cooking pot 27 is tilted with the support member 24 so that the cooking material 34 comes into contact with the inside part. By continuing to heat and rotate the cooking pot 27, stir-frying the cooking ingredients 34 is automatically completed.

[0007]

[Problems to be Solved by the Invention] As described above, the conventional electric cooking device shown in FIG. The cooking container 13 is inserted in an inclined manner and is engagedly connected to the drive motor 4 through the receiving part 17 to cook while rotating the cooking container 13 in an inclined manner. Therefore, when frying dishes, oil, vegetables, etc. are scattered on the surrounding walls, floors, etc., which not only makes cleaning up a hassle, but also causes unsanitary conditions and may be harmful to health if cleaning is neglected. Furthermore, since the rotating cooking container 13 is exposed on the inclined surface 2 of the support 1, there is a risk that fingers may come into contact with the rotating cooking container 13 and get injured.

On the other hand, in the electromagnetic cooker shown in FIG. 6, the cooking pot 27 is covered with a lid 30 screwed onto the processing container 22, so that oil and vegetables will not be scattered. however,
Since the upper surface of the flange 32 of the cooking pot 27 contacts the lower surface of the slip ring 33 of the stationary lid body 30 and rotates, the sliding portion rubs and hinders the rotation of the cooking pot 27. In particular, the surface of the higher sliding portion (on the left side of the figure) may be scraped off due to rotational wear, and scraped metal powder may fall into the cooking pot 27. If metal powder falls into the cooking pot 27 and mixes with the cooking ingredients 34, the hard-earned cooking will be ruined. Further, since the cooking pot 27 cannot be removed from the processing container 22, there are problems such as poor cleaning of the cooking pot.

The present invention was made in order to solve the problems of the conventional device as described above, and it prevents oil and vegetables from scattering and soiling the surrounding area, and also prevents metal powder produced by rotational friction. The purpose is to realize a rotary cooking machine that does not cause cooking quality to deteriorate due to mixing of cooking ingredients with cooking ingredients.

0010

[Means for Solving the Problems] The present invention provides a main body of a cooking machine that rotatably holds and houses a cooking pot, a heating means provided in the main body for heating the cooking pot, and a heating means housed in the main body that heats the cooking pot.

A rotary cooking machine is constructed in which a lid is provided and a pot lid is rotatably attached to the container lid.

[0011] Furthermore, a rotary cooking machine is constructed in which the pot lid can be freely removed from the container lid.

Furthermore, the rotary cooking machine is constructed such that at least the inner surfaces of the cooking pot and the pot lid are surface-treated with an anti-affinity substance.

[0013]

[Operation] When the container lid is attached to the main body and covers the top of the cooking pot, the cooking pot is covered by the pot lid on the inner surface of the container lid, and the cooking pot is rotated while being heated by the heating element and rotating means. You can start. The container lid attached to the main body and covering the top of the cooking pot remains stationary, but the pot lid rotates together with the cooking pot to proceed with cooking. After cooking is complete, the pot lid is removed from the container lid and cleaned together with the cooking pot. The inner surfaces of the cooking pot and pot lid are surface-treated, so any adhering cooking materials can be easily wiped off.

The contact shaft 45 is loosely fitted into the cylindrical shaft 44 so as to be able to move within a certain range in the vertical direction, and is exposed on the upper surface of the cylindrical shaft 44 in a normal state due to an upward force applied by a spring 47.

Although not shown, a temperature sensor such as a thermistor that detects temperature changes is provided at the tip of the contact shaft 45, and a displacement sensor that detects displacement in the vertical direction is also provided. The displacement sensor detects the presence or absence of a cooking pot, which will be described later, and the temperature sensor detects the temperature to control the cooking temperature. 48 is a coil base, and 49 is an induction heating coil.

51 is a pot holder base, 52 is a cooking pot, 53
is a stirring blade. The pot holder base 51 is fixed to the upper end of the cylindrical shaft 44 and faces the opening 41.
Through this, the cooking pot 52 is placed on the pot holder base 51 in a freely removable manner. A magnetic material is used for the cooking pot 52, and an iron-based metal material with high relative magnetic permeability and high specific resistance is particularly suitable. 55 is a rotation motor, 56 is a motor shaft, 57 and 5
8 is a pulley, and 59 is a belt suspended between both pulleys 58 and 59. The pulley 58 is fixed to the cylindrical shaft 44, and the rotational force of the rotation motor 55 is transmitted to the pot holder base 51 via a belt 59.

60 is a container lid. 61 is a handle, 62 is a hinge, and 63 is a latch. In addition, 64 is a container lid 60
65 is a coil spring, 66 is a push plate having a shaft portion, 67 is a dish plate, and 68 is a knob. These mounting shafts 64 and the like constitute a mounting bracket 69. The structure in the vicinity of the mounting bracket 69 is shown enlarged in FIGS. 2 and 3. 71 is a groove formed in the mounting shaft 64, 72 is an engagement plate, and 73 is an engagement hole. The engagement plate 72 is fixed to the knob 68 with a screw 74, and the opening of the groove 71 is elastically expanded to be inserted into the groove 71.

75 is a pot lid; 76 is a wear-resistant bearing; 7
7 is a packing. The pot lid 75 is removably attached to the container lid 60 by a mounting fitting 69. 78 and 79
is a steam vent provided on the container lid 60 and the pot lid 75. The steam vents 78 and 79 are preferably fitted with replaceable filters for filtering oil mist. Then,
When the latch 63 is removed and the handle 61 is lifted, the container lid 60 rotates together with the pot lid 75 about the hinge 62, and the top surface of the main body 30 is opened. The inner surfaces of the cooking pot 52 and the pot lid 75 are coated with Teflon (trade name: tetrafluoroethylene resin).
A coating layer of an anti-affinity substance such as

80 is a base, 81 and 82 are holding walls erected on the left and right sides of the base 80, and 83 is an inclined shaft. The tilting shaft 83 is provided on the X-X axis, and the main body 40 is held rotatably about the X-X axis from both sides by the holding walls 81 and 82. 85 is a tilting motor disposed within the right holding wall 82, and 86 is an angle sensor that detects the tilt angle of the main body 40. The angle sensor 86 detects the tilt angle of the main body 40, and the rotation stop position of the tilt motor 85 is controlled by this detection signal. Reference numeral 87 represents an operation unit equipped with a display, and reference numeral 88 represents a control unit consisting of an electronic circuit including a microcomputer.

The cooking operation of the embodiment of the present invention having such a configuration will be explained using an example of cooking fried rice.

When the cooking pot 52 is set in the opening 41 of the main body 40 and the power switch of the operating section 87 is turned on, the control section 8
8 operates, the tilting motor 85 is driven, and the tilting shaft 83 rotates and tilts the cooking pot 52 around the XX axis. The tilt angle of the cooking pot 52 is detected by an angle sensor 86, and when the set angle is reached, the drive of the tilt motor 85 is stopped.

[0023] Here, the induction heating coil 49 is
When a high-frequency excitation current of about KHz is applied, an alternating eddy current flows through the pot holder base 51 and inside the cooking pot 52 within the magnetic field due to electromagnetic induction, generating Joule heat. As a result, the heat generated by electromagnetic induction begins to rapidly heat the cooking pot 52. When the cooking pot 52 is heated, an appropriate amount of edible oil is put into the cooking pot 52. Then, the rotation motor 55 is driven to rotate the cooking pot 52 around the Z axis via the pulleys 57, 58 and the belt 59, thereby spreading the heated oil over the inner surface of the cooking pot 52.

[0024] When the oil is properly distributed, open the cooking pot 52.
The rotation of the container is stopped, meat and vegetable ingredients are added, and the container lid 60 is closed by rotating around the hinge 62. When the container lid 60 is closed and the latch 63 is locked, the peripheral portion of the pot lid 75 receives the expansion force of the coil spring 65 and comes into pressure contact with the edge of the cooking pot 52 via the packing 77. Then, when the rotation motor 55 is driven again, the cooking pot 52 rotates the pot lid 75 in the direction of the arrow.
The push plate 66 is in frictional contact with the push plate 66, and is supported by the shaft portion of the push plate 66 to rotate together. Since the rotation of the pot lid 75 is supported by a wear-resistant bearing 76, the sliding portion does not wear out due to rotation. Even if the sliding parts become worn, the bearing 7
A saucer-shaped tray plate 67 placed below the friction powder 6 prevents the friction powder from falling.

On the other hand, the vegetables placed in the tilted and rotating cooking pot 52 are automatically stirred while being caught by the stirring blades 53, and stir-fried. As cooking progresses, steam generated by heating water contained in the vegetables is released to the outside through steam vents 78 and 79 of the pot lid 75 and container lid 60. Since the pot lid 75 contacts the edge of the cooking pot 52 with appropriate spring pressure and seals the gap, even if the slope is deep, the boiling liquid and cooking ingredients will not spill out from the periphery of the cooking pot 52. Never happened.

[0026] After that, the rice and seasonings that have already been cooked are placed in the cooking pot 52 in the same manner, and then the container lid 60 is used to cover the rice and the ingredients are heated and rotated for a certain period of time. Mix properly and fry well. When the cooking is finished, the induction heating coil 49 is turned off, the cooking pot 52 is returned to the horizontal position, and rotation and heating are stopped. Once the appropriate preheating time has passed, the finished fried rice is served and the meal can begin.

After eating, when the handle 61 is grasped to open the container lid 60 and the knob 68 is pulled in the direction of the dotted arrow in FIG.
The engagement with is released. Then, the plate plate 67 and the pot lid 75 are removed from the mounting shaft 64. The removed pot lid 75 is washed individually together with the cooking pot 52 taken out from the main body 40.

At this time, since the inner surfaces of the cooking pot 52 and the pot lid 75 are surface-treated with an incompatible substance, there is little chance of burning of the cooking ingredients, and the water can be wiped off with a detergent-dipped sponge or the like. Just apply it and the oil will be thoroughly washed away. Pot lid 7
The dish plate 67 covering the vicinity of the lower surface of the bearing 76 of No. 5 is also washed at the same time. After cleaning and wiping off moisture, the pot lid 75 is fitted onto the mounting shaft 64, the engagement plate 72 is inserted into the split groove 71 (as indicated by the solid line arrow in FIG. 4), and the pot lid 75 is attached to the container lid 60 again.

In the above embodiment, the pot holder base 51 fixed to the cylindrical shaft 44 is connected to the pulleys 57, 58 and the belt 5.
9 has been described as an example, but it may also be driven by gears or rollers. Further, although not specifically described in the embodiment, if part or all of the container lid 60 is made of a transparent material such as tempered glass, it becomes convenient to observe the cooking status. Furthermore, although the case of the mounting bracket 69 in which the engagement plate 72 fixed to the knob 68 with the screw 75 is inserted into the split groove 71 of the mounting shaft 64 has been described, not only the means for attaching the pot lid 75 but also the tilting means and the driving means are also used. It is not limited to the examples. Further, although the cooking pot 52 is simply placed on the pot holder base 51, an engaging means may be provided to ensure the torque is transmitted.

[0030]
