FIG. 4B is a perspective view of the lid 12 in a closed state. In the present embodiment, for the sake of convenience, the following description will be made in detail with the ceiling side as the upper side and the floor F side as the lower side in the kitchen. The energy converter of the present invention is applied to the IH cooker / mill mixer 1 of the present embodiment.

  The IH cooker / mill mixer 1 of this embodiment is installed in a kitchen as shown in FIGS. 1 and 2A, and is connected to a commercial power source on a cooking table 11 having a flat surface 11a on the upper surface. Thus, a magnetism generating mechanism section 20 for generating an alternating magnetic field and / or a rotating magnetic field is provided on the flat surface 11a.

  The cooking table 11 is installed in the vicinity of the horizontal wall W1 of the kitchen. On the flat surface 11a of the cooking table 11, a lid (housing) 12 leaning against the horizontal wall W1 is provided. It is called an open state. The lid 12 has a flat surface 12c on the surface (lower surface) opposite to the surface in contact with the horizontal wall W1, and the flat surface 12c faces the flat surface 11a of the cooking table 11 as shown in FIG.

  Further, the horizontal wall W <b> 1 is provided with a not-shown convex portion in the vicinity of the cooking table 11. The lid body 12 is provided with a concave portion 12g-1 that engages with the convex portion on a surface (upper surface) 12a in contact with the lateral wall W1, and the convex portion and the concave portion 12g- in a state where the lid body 12 is leaned against the lateral wall W1.

  In the IH cooker / mill mixer 1 of this embodiment, as shown in FIG. 2 (b), the lid 12 has a rotating mechanism 30 that is driven to rotate by the rotating magnetic field generated by the magnetism generating mechanism 20. When the lid body 12 is opened, that is, as shown in FIG. 2A, the flat surface 12c of the lid body 12 is separated from the flat surface 11a of the cooking table 11 and the lid body 12 is opened. When the lid 12 is closed, that is, as shown in FIG. 2B, the plane 12c of the lid 12 is in contact with the plane 11a of the cooking table 11, so that it functions as a mill mixer. Yes.

  Further, inside the cooking table 11, a power cable and a plug 24b for supplying power to an inverter circuit 23 of the magnetism generating unit 20 described later are connected to a commercial power source (single-phase 100V frequency 50 / 60HZ) not shown.

  The IH cooker / mill mixer 1 of the present embodiment is based on the principle of “AC energy conversion drive device” previously invented by the inventor of the present application and disclosed in JP-A-10-108426. Detailed description will be omitted and will be described below. Here, the case where the IH cooker / mill mixer 1 functions as an IH cooker will be described first. 3 is a schematic configuration diagram of the magnetism generating mechanism section 20, FIG. 4A is a conceptual front view of the coil unit 22 of FIG. 3, FIG. 4B is a top view of FIG. 4A, and FIG.

  As shown in FIG. 3, the magnetism generating mechanism 20 constitutes a flat surface 11 a of the cooking table 11 and has heat resistance, water resistance, impact resistance, and electromagnetic wave transmission, for example, a glass top plate (plate part). 21, a coil unit 22 positioned below the top plate 21, and a coil unit 22 by controlling a current supplied from a commercial power source (single-phase 100 V frequency 50/60 HZ) via a power cable and a plug (not shown). The inverter circuit 23 is provided on the flat surface 11a of the cooking table 11 as shown in FIGS. 2 (a) and 2 (b). The inverter circuit 23 is operated by, for example, a touch operation type operation button 11b. Changes the phase and frequency of the current.

  The operation button 11b is provided with a change-over switch 11b ', and can be used by switching between an IH operation button and a mill mixer operation button by the change-over switch 11b'. Further, the bottom surface of the cooking table 11 and the top plate 21 are provided with vent holes for heat dissipation (not shown).

  As shown in FIG. 4B, the coil unit 22 includes, for example, a plurality of (eight in this embodiment) rotational drive coils 22C arranged on a circumference having a diameter of 120 mm, the inside of the rotational drive drive coils 22C, On the outer circumference, there are provided an inner alternating coil 22A and an outer alternating coil 22B for induction heating in which a conductive wire is wound along each circumference.

  As shown in FIG. 4A, the drive coil 22C is formed of a magnetic material formed of a soft magnetic material such as a ferrite magnetic material upright on a magnetic pedestal 22c-1 formed of a laminated body of silicon steel plates or a high resistance ferrite magnetic material. A conductive wire is wound around the core 22C-2, and in this embodiment, the number of electrical angles for one mechanical angle per phase is two.

  The inner alternating coil 22A has an inner diameter of about 40 mm and an outer diameter of about 80 mm, and the outer alternating coil 22B has an inner diameter of about 160 mm and an outer diameter of about 200 mm. It is configured. The inner alternating coil 22A and the outer alternating coil 22B are formed so that the end of winding of the inner alternating coil 22A and the winding start of the outer alternating coil 22B are continuous in the same direction, for example, counterclockwise. It is wound and connected to the same supply terminal of the inverter circuit 23. At this time, the outer alternating coil 22B is provided with a switch capable of selecting ON / OFF of the current flow.

  The inverter circuit 23 includes a Sin / Cos two-phase inverter circuit. When the operation button 11b for the mill mixer (see FIG. 1 and FIG. 2) is operated, the commercial power is reduced to 100V or less and several tens of amperes depending on the requested load. The frequency is converted to 150 to 800 Hz and the current is controlled to flow through the driving coil 22C. The function as a mill mixer will be described in detail later.

  The inverter circuit 23 selects one or more of the inner alternating coil 22A, the outer alternating coil 22B, and the driving coil 22C in accordance with the requested load when operating the IH operation button 11b. Control to flow. This selection method will be described later in detail.

  At this time, in order to use the driving coil 22C for rotational driving as a coil for dielectric heating, it is necessary to generate an alternating magnetic field by the driving coil 22C. In order to generate an alternating magnetic field, that is, to cause the same current to flow through the coil 22C without generating a rotating magnetic field and to make the direction of the magnetic flux one direction, the winding direction of the driving coil 22C is usually changed to one direction. Thus, it is necessary to provide switches for each driving coil 22C to control each of them, and the control becomes complicated.

  Therefore, in this embodiment, by providing a phase shift circuit in the inverter circuit 23 without changing the winding direction, the two phases Sin and Cos are changed to two phases Sin and Sin, and all the driving coils 22C For example, by flowing a current of a frequency of 30 kHz, the direction of the magnetic flux is made the same direction with the same current. The coils 22A, 22B, and 22C for driving all use litz wires.

  The cooking table 11 having the magnetism generating mechanism 20 configured as described above has an upper surface, that is, a flat surface of the top plate 21 with the lid 12 opened, as shown in FIGS. 11a, cooking utensils 5 such as pans, pans, kettles, etc., made of electromagnetic derivatives such as iron and stainless steel, cooking utensils 5 using a metal plate at the bottom, special cooking in which electromagnetic derivatives are kneaded A so-called induction heating is performed by placing the utensil 5 and the like, and operating the IH operation button 11b to flow an electric current to the coil unit 22 via the inverter circuit 23, thereby generating an eddy current in the cooking utensil 5 and heating it. Can be used as an IH cooker.

At this time, as shown in FIGS. 4A and 4B, the cooking utensil 5 is a pan having a different size, for example, a pan 5-1 having a diameter of 120 mm, a pan 5-2 having a diameter of 220 mm, and a pan 5-3 having a diameter of 280 mm. When the IH operation button 11b is operated by the user according to the size of the pan to be used, the inverter circuit 23 selects the respective coils 22A, 22B, and 22C as shown in Table 1 below. Then, the current is controlled to flow.

  As shown in Table 1, for example, when the pan 5-2 is used, in addition to the inner alternating coil 22A for induction heating, the outer alternating coil 22B is used as described above, so that only the inner alternating coil 22A is used. Compared with the case of, the pan 5-2 can be heated earlier.

  For example, when using the pan 5-3, in addition to the inner alternating coil 22A and the outer alternating coil 22B for dielectric heating, the driving coil 22C can be used as a dielectric heating coil as described above. The pan 5-3 can be heated quickly.

  At this time, as described above, since the inner alternating coil 22A and the outer alternating coil 22B have the same winding direction and the same current flowing direction, the current flows through both the coils 22A and 22B. As shown on the left side of FIG. 5, the generated magnetic flux is counterclockwise around the inner alternating coil 22 </ b> A and the outer alternating coil 22 </ b> B when the current flows from the back side to the near side of the page.

  Then, in the magnetic core 22C-2 of the driving coil 22C, the magnetic flux generated by the inner alternating coil 22A is directed from the pan 5 side to the coil unit 22 side, that is, downward in the drawing, and is generated by the outer alternating coil 22B. Is from the coil unit 22 side toward the pan 5 side, that is, upward in the drawing, and the downward magnetic flux and the upward magnetic flux cancel each other, thereby preventing the magnetic core 22C-2 from absorbing and deteriorating the magnetic flux.

  Similarly, as shown on the right side of FIG. 5, when the current flows from the front side to the back side of the sheet, the coil turns clockwise around the inner alternating coil 22A and the outer alternating coil 22B, and the magnetic core 22c-2. Since the magnetic fluxes generated in each are in opposite directions, the downward magnetic flux and the upward magnetic flux cancel each other, thereby preventing the magnetic core 22C-2 from absorbing and deteriorating the magnetic flux.

  Since the magnetic fluxes cancel each other in the magnetic flux core 22c-2, the magnetic flux has a large diameter surrounding the inner alternating coil 22A and the outer alternating coil 22B. Can be heated well.

  Since the coil to be used can be selected according to the size of the cooking utensil 5 as described above, the magnetism generation mechanism unit 20 can efficiently perform IH cooking.

  In this embodiment, the method of selecting the coil used for dielectric heating is as shown in Table 1, but the present invention is not limited to this. For example, only the outer alternating coil 22B, the inner alternating coil A and the outer alternating coil are used. A combination such as the coil 22B, the outer alternating coil B, the driving coil C, and the driving coil C alone may be selectable or may be changed as appropriate.

  Further, in order to reduce the magnetic flux absorption deterioration in the magnetic core 22C-2 when the inner alternating coil 22A or the outer alternating coil 22B is used alone, the coil 22A and / or the coil 22B is replaced with the magnetic core 22C-2. It may be arranged at a predetermined distance from the driving coil 22C.

  Next, the case where the IH cooker and mill mixer 1 functions as a mill mixer will be described. 6 is a perspective view when the mill mixer 40 is mounted on the lid 12 of the IH cooker / mill mixer 1, FIG. 7 is an enlarged cross-sectional view of the main part including the rotating mechanism 30, and FIG. 8 is a perspective view of the mill mixer 40. FIG.

  As shown in FIG. 2B, the rotation mechanism 30 functions in a state where the lid 12 is closed. When the lid 12 is closed, the plane 11a and the lid 12 of the cooking table 11 shown in FIG. The flat surface 12c is in contact and functions in this contact state.

  As shown in FIGS. 2B and 7, the upper surface 12a of the lid body 12 is formed with a hole portion 12e substantially at the center, and a protruding portion 42a of a mill mixer 40 described later is formed on the upper surface of the hole portion 12e. Three recessed portions 12d to be mounted are formed.

  As shown in FIG. 7, the rotating mechanism 30 includes a rotating plate 31 formed of a soft magnetic metal material such as iron or aluminum, and a support shaft that is integrally attached to the approximate center of the rotating plate 31. 32, the support shaft 32 is provided with a bearing B between the lower wall standing part constituting the flat surface 12 c of the lid 12, and between the center hole of the hole 12 e and the support shaft 32. A bearing B is interposed, and the upper end protrudes from the central hole of the hole 12 e and is assembled so as to rotate together with the rotating plate 31. The rotation mechanism unit 30 includes a rotation transmission plate (rotational force transmission unit) 34 that is assembled to the upper end of the support shaft 32 and includes four fitting teeth 33 in a circular shape on the upper end surface.

  The rotating plate 31 may be formed of any one of iron and aluminum, iron and copper, iron and semi-hard aluminum material, iron and aluminum and semi-hard aluminum material, and composite material of iron, copper and semi-hard aluminum material. it can.

  The rotating mechanism 30 configured as described above is such that the rotating plate 32 and the coil unit 22 are magnetic, for example, about 5 to 10 mm in a state where the flat surface 11a of the cooking table 11 and the flat surface 12c of the lid 12 shown in FIG. It is assembled so as to separate the gap G.

  When the IH cooker / mill mixer 1 is used as a mill mixer, the mill mixer 40 is attached to the rotation mechanism 30 as shown in FIG. As shown in FIGS. 7 and 8, the mill mixer 40 is inserted through the glass container main body 41 for containing food such as vegetables and fruits, a base 42 fixed to the bottom of the glass container main body 41, and the base 42. The fin shaft 44 provided at the upper end with the fin blades 43 disposed inside the container body 41 and the lower end surface of the fin shaft 44 are fitted to the fitting teeth 33 of the rotation transmission plate 34 described above. And a fin turntable 45 in which a fitting hole 45a is formed. The fin blades 43, the fin shaft 44, and the fin rotating plate 45 constitute a stirring member that is rotationally driven by the rotation transmission plate 34.

  Further, on the lower surface of the base portion 42, three projecting portions 42a for mounting on the concave portion 12d of the upper surface 12a of the lid body 12 are formed. It functions as a restricting part for preventing the rocking movement of. Further, a guide cylinder 42b for the fin turntable 45 protruding downward is provided on the lower surface of the base portion 42.

  The IH cooker / mill mixer 1 equipped with the mill mixer 40 configured as described above is for rotationally driving the coil unit 22 of the magnetism generating mechanism section 20 when the operation button 11b for the mill mixer is operated. When a current flows through the coil, a rotating magnetic field is generated from the rotational driving coil, and the generated rotating magnetic field induces an eddy current due to electromagnetic induction in the rotating plate 31 of the rotating mechanism unit 30, and the rotating plate 31 is inductively equivalent. The rotating plate 31 rotates as an induction electromagnet such as a plate magnet. As a result, the rotating plate 31 repels or attracts the magnetic field of the magnetism generating mechanism section 20 and slips so as to rotate with respect to the magnetism generating mechanism section 20 and smoothly rotates. As the rotating plate 31 rotates, the support shaft 31 and the rotation transmitting plate 34 also rotate.

  And the fin rotation board 45 mounted | worn by fitting the fitting tooth 33 and the fitting hole 45a to this rotation transmission board 34, and the fin axis | shaft and fin blade 43 which rotate integrally with the fin rotation board 45 rotate. The rotation is transmitted from the transmission plate 34 and rotates together with the rotation plate 31.

  Thereby, when food etc. are put in the container main body 41, juice can be produced | generated by the food inside the container main body 41 being grind | pulverized by the fin blade 43a of the fin blade | wing 43, and stirring. In addition, if this fin blade | wing 43 is replaced | exchanged for the thing which does not have the fin blade 43a, for example, it can also be used as a use which mixes the contents of the container main body 41, for example, a bread kneader etc. In this way, the IH cooker / mill mixer 1 is used as a stirring device for performing pulverization, stirring, and the like. When not used, the mill mixer 40 is accommodated in a kitchen shelf or the like as shown in FIG.

  The mill mixer 40 of the present embodiment is a cooking utensil that is used with food, but the present invention is not limited to this, and for example, a simple washing machine that removes dirt when light dirt such as a cloth is placed. Etc. can also be used.

  In this embodiment, the lid 12 and the cooking table 11 can be opened and closed as described above. However, the present invention is not limited to this, and the lid 12 and the cooking table 11 can be opened and closed with the plane 12c and the plane 11a inside. If it becomes the structure which becomes, you may make it open and close freely, for example by providing a hinge. In this case, an engaging member for engaging the wall W1 and the lid body 12 is provided so that the lid body 12 can be kept open.

  Further, the lid body 12 may not be configured to be openable and closable as described above. In this case, for example, an opening (not shown) may be provided in the cooking table 11, and the lid 12 may be accommodated in the opening when not used as a mill mixer.

  In the above-described embodiment, the cooking table 11 is used as an IH cooker for cooking by placing the cooking utensil 5 on the upper surface, that is, the flat surface 11a of the top plate 21, but for example, a container formed of an electromagnetic derivative and the container The rotating plate 31 and the support shaft 32 that are arranged to be rotatable via the bearing B, and a mesh container that rotates in conjunction with the support shaft 32, for example, water in the container, Vegetable warm water washing in which each vegetable is put and the rotating plate 31 is rotated by the same principle as the rotation mechanism unit 30 and the water in the container is heated by the principle of the magnetic generation mechanism unit 40 to wash the vegetable with warm water. It can also be used as a container.

  Next, the IH cooker and mill mixer of the second embodiment will be described. In the IH cooker / mill mixer of this embodiment, the same parts as those of the IH cooker / mill mixer 1 of the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only the mechanism 30 ′ will be described in detail. FIG. 9 is a perspective view of a housing 12 ′ of the IH cooker / mill mixer according to the second embodiment, and FIG. 10 is a schematic cross-sectional view of the main part of FIG. 9.

  As shown in FIG. 9, the housing 12 ′ of the IH cooker / mill mixer of the present embodiment includes two rotating parts A and B that have different rotational speeds. The rotation mechanism unit 30′-1 of the rotation unit A is a deceleration transmission unit that transmits the rotational drive by the rotating magnetic field of the magnetism generation mechanism unit 20 to other rotation members at a reduced speed in addition to the configuration of the rotation mechanism unit 30 of the above embodiment. 10 and is formed in a hole 12e-1 formed on the upper surface 12a of the lid 12 as shown in FIG.

  Further, the rotation mechanism portion 30'-2 of the rotation portion B is formed in a hole portion 12e-2 provided at a predetermined distance from the hole portion 12e-1.

  The rotation mechanism 30′-1 is disposed between two upper and lower bearings B through which the support shaft 32 shown in FIG. 7 is inserted. As shown in FIG. The first gear 35 is provided with teeth 35a on the outer periphery and is configured to rotate integrally with the rotation of the support shaft 32 '. Yes. The first gear 35 is connected to a second gear 36 having teeth 36a meshing with the teeth 35a on the outer periphery so as to mesh the teeth 35a and the teeth 36a in parallel. The first gear 35 and the second gear 36 have a diameter, the number of teeth, and the like so that the reduction ratio is 10 to 100.

  The second gear 36 is provided with bearings B at the top and bottom, and a support shaft 32 ′-2 is inserted through the center thereof, so that the shaft 32 ′-2 rotates integrally with the second gear 36. It is configured. A rotation transmission plate 34 having four fitting teeth 33 in a circular shape on the upper end surface is assembled to the upper end of the support shaft 32'-2 in the same manner as the rotation mechanism portion 30'-1.

  As described above, the rotating magnetic field generated by the magnetism generating mechanism section 20 and the rotating plate 31 of the rotating mechanism section 30′-1 together with the support shaft 32 ′ of the rotating mechanism section 30′-1, the first gear 35, and the rotation transmission. The plate 34 rotates at the same speed, and at the same time, the second gear 36 of the rotation mechanism section 30′-2 meshing with the first gear 35 rotates at a rotation speed reduced according to the reduction ratio, and the rotation mechanism section 30. The '-2 support shaft 32'-25 and the rotation transmission plate 34 rotate at the same speed as the second gear 36.

  As a result, the rotation mechanism plate 30′-2, that is, the rotation transmission plate 34 of the rotation unit B rotates at a speed lower than the rotation by the rotation drive by the rotating magnetic field of the magnetism generation mechanism unit 20, and thus is connected to the rotation transmission plate 34. This reduced rotation can be transmitted to other rotating members. At this time, the first gear 35, the second gear 36, the support shaft 32'-2 of the rotation mechanism section 30'-2, and the rotation transmission plate 34 function as a deceleration transmission section. Instead of this speed reduction mechanism, a speed reduction mechanism using a planetary gear or a toothed pulley may be used.

  Thus, since rotation mechanism part 30'-1 is equipped with the above-mentioned deceleration transmission part, the mill mixer connected and used for an IH cooker and mill mixer requires high torque. However, the driving force can be adjusted according to the type of the mill mixer.

  In the above-described embodiment, the lid 12 and the casing 12 ′ have the bottom surface 12c. However, the present invention is not limited to this, and the rotating plate 31 (see FIG. 7) includes the magnetism generating mechanism unit 20 and the magnetism. The casings 12 and 12 ′ may not have the lower surface, that is, the flat surface 12 c as long as they can be opposed to each other with a gap G between them, that is, if they do not contact the flat surface 11 a of the cooking table 11.
