  The present invention relates to an improvement in heating efficiency of a cooking device.

  2. Description of the Related Art In recent years, devices that perform electronic control using a microcomputer, IC, etc., for heating power control of a cooking device that uses electric power, city gas, and LP gas as heat sources have become common.

  Among them, cooking equipment that uses the principle of electromagnetic induction has been evaluated in terms of safety because it does not use fire, and has been introduced into the market. It has a thermal power, thermal efficiency, and running cost that is equal to or greater than that of other gases. In view of this point, products that are easy to use continue to be proposed, and are expected to spread widely in the future (see, for example, Patent Document 1).

  FIG. 6 is a configuration diagram showing a cross section of a conventional cooking device described in Patent Document 1. As shown in FIG. As shown in FIG. 6, it comprises an operation unit 101, a heating unit 102, a third control mode 107, a control unit 108, a top plate 109, an object to be heated 110, and heating position guide light emitting units 112a and 112b. .

  That is, by placing the object 110 to be heated on the top plate 109 and inputting it to the operation unit 101, the heating unit 102 is energized by the third control mode 107 in the control unit 108 and heating is started.

  Further, after input to the operation unit 101, the heating position guide light emitting units 112a and 112b installed on the outer periphery of the heating unit 102 emit light, and the user visually recognizes the light La1 and La2 transmitted through the top plate 109. The heating position is roughly grasped, and the object to be heated 110 is moved so that the light emission position is arranged in a balanced manner with the object 110 to be heated, and used as a position with good heating efficiency.

  In some cases, the heating position guide light emitting units 112a and 112b are not provided. In this case, the user places the object 110 to be heated at a marked position (not shown) on the top plate 109 in a scale. I was using it.

  However, in the conventional cooking device, even if the light from the heating position guide light emitting units 112a and 112b is visible from the bottom surface of the top plate 109, a pan or the like to be heated 110 is placed. In this case, the user does not know whether the position is the most efficient heating position, and although it is placed at a position that serves as a guide on the upper surface of the device body, there are many parts that depend on the user's intuition, or a heating position guide In the absence of the light emitting portions 112a and 112b, there was a problem that the position with higher heating efficiency was not well understood.

(Embodiment 1)
FIG. 1 shows a configuration diagram of a cooking device according to the first embodiment of the present invention.

  In FIG. 1, by inputting to the operation unit 1, the heating control of the heating unit 2 is performed in the third control mode 7 of the control unit 8. At that time, the heating unit 2 has a heating coil (not shown) that is substantially concentric (symmetric with respect to the center), generates a magnetic field by flowing a high-frequency current through the heating coil, and includes a conductive material to be heated. The object 10 is induction-heated. At the time of heating control, magnetic lines of force act on the object 10 placed on the top plate 9 on the surface facing the heating coil and on the heating part 2 on the surface facing the eddy current flowing in the object 10 to be heated. A repulsive action occurs. For example, when the positions of the object to be heated 10 and the heating unit 2 are shifted in the center positions, the repulsive action of the lines of magnetic force causes a situation where the repulsive forces at the positions pa and pb are not uniform. If the above-mentioned state occurs, the balance control unit 3 that detects the equilibrium state of the heating unit provided in the vicinity of the heating unit 2 in the first control mode 4 detects the repulsive force applied to the heating unit 2.

  Further, the balance degree detection unit 3 is a sensor (not shown) for detecting the inclination of the heating unit 2 to detect the inclination of the heating unit 2 so that the degree of inclination generated as a result of the unbalance of the repulsive force as described above can be easily achieved. It can be detected.

  In addition, by configuring the balance detection unit 3 with a plurality of sensors that detect inclination, it is possible to accurately recognize inclination recognition in a wide range.

  In addition, the balance degree detection unit 3 is integrated into the heating unit 2 so that the degree of inclination of the heating unit can be detected more easily, and the surroundings of the heating unit 2 can be simplified. It becomes.

  In addition, by disposing the balance degree detection unit 3 at substantially the center of the heating unit 2, the degree of inclination at the center of the heating position can be easily recognized.

  In addition, by providing the balance detection unit 3 at a substantially central position of the heating unit 2 and a predetermined position from the approximate center to the outer periphery, it is possible to improve detection accuracy when the inclination of the entire surface of the heating unit 2 is delicate in each part. It becomes possible.

  Further, by setting the balance of the heating unit 2 after a predetermined time has elapsed, the content of the object to be heated 10 has just been placed at a predetermined heating position, and the object to be heated 10 moves due to the stress. The situation and the initial unstable timing at the time of cooking, such as when the user repositions the object 10 to be heated, can be eliminated, and the balance can be accurately recognized.

  In addition, after detecting the degree of balance of the heating unit 2 over a predetermined time, by repeating the operation of transmitting the information to the second control mode 6 that outputs a signal to the position correction unit 5 at a predetermined interval, the user can It is possible to cope with the case where the object to be heated 10 is replaced or when the object to be heated 10 having a different size is used.

  Further, if the equilibrium state of the heating unit 2 falls within a certain range in the balance detection unit 3, it means that the balance is maintained. Therefore, there is no need to correct the position of the heating unit 2. In the second control mode 6, an unnecessary control operation can be omitted by setting the control unit 8 to stop.

  If the equilibrium state of the heating unit 2 falls within a certain range in the balance detection unit 3, the second control mode 6 for correcting the position of the heating unit 2 is stopped, but again after a predetermined time has elapsed, By using the control unit 8 for confirming whether the two equilibrium states are within a certain range, it is possible to cope with various ways of placing the object to be heated 10 and cooking methods.

  Moreover, the position correction | amendment part 5 makes the position which the to-be-heated target object 10 puts in position within the predetermined range preset on the apparatus main body (not shown) top plate upper surface, and is mischievous. It is possible to avoid making the configuration of the device main body large.

  Moreover, the heating position guide light-emitting part (not shown) provided integrally with the outer periphery of the heating part 2 and the balance degree detection part 3 are further integrated so as to be heated during cooking. It becomes easy to visually recognize the position where the object 10 is placed, and the configuration including the heating unit 2 can be made compact.

  Further, when the equilibrium state of the heating unit 2 falls within a certain range in the balance degree detection unit 3, the lighting method of the heating position guide light emitting unit provided integrally with the outer periphery of the heating unit 2 is set in advance. By making it shine with a pattern, it can be confirmed that the user is cooking with good heating efficiency.

  Further, when the equilibrium state of the heating unit 2 falls within a certain range in the balance degree detection unit 3, the user is heated by displaying character information or a flashing sign at a predetermined position of the operation unit 2 for performing operation input. It is possible to make it known whether it is an efficient state of mind.

  In FIG. 1, the repulsive force applied to the heating unit 2 is recognized as an inclination applied to the entire heating unit. However, the heating unit 2 is not inclined and the vertical direction is fixed, and only the balance detection unit 3 is used. It does not matter if it is recognized by capturing the repulsive force generated by the action of the lines of magnetic force.

(Embodiment 2)
FIG. 2 shows a block diagram of a cooking device according to the second embodiment of the present invention.

  In FIG. 2, by inputting to the operation unit 1, the heating control of the heating unit 2 is performed in the third control mode 7 of the control unit 8. At that time, lines of magnetic force act between the object to be heated 10 placed on the top plate 9 and the heating unit 2, and a repulsive action occurs. For example, when the positions of the object to be heated 10 and the heating unit 2 are shifted in the center positions, the repulsive force acting on pa and pb due to the repulsive action of the lines of magnetic force results in a situation where the repulsive force is not uniform. . If the above-mentioned state occurs, the balance degree detection unit 3 that detects the equilibrium state of the heating unit 2 provided in the vicinity of the heating unit 2 in the first control mode 4 generates the repulsive force applied to the heating unit 2. Detect imbalance.

  Further, the heating unit 2 has a configuration in which the heating unit 2 itself is fixed by a variable fixing unit 11 having a degree of freedom in the vertical direction and the horizontal direction, so that the object to be heated 10 and the heating unit 2 can be relatively compared in the initial stage of heating. Although the position is affected, when the repulsive force generated by the action of the magnetic lines of force occurs between the object to be heated 10 and the heating unit 2 in an unbalanced manner, for example, the repulsive force is changed to pa and pb in the figure. When an imbalance occurs, the heating unit 2 generates an inclination by the function of the variable fixing unit 11.

  At this time, the variable fixing part 11 receives the above-mentioned stress and moves in the position direction pc where the repulsive force is balanced by the way of applying the weight of the heating part 2 when tilted, particularly the horizontal direction component, and the repulsive force is balanced. It will be fixed. Then, whether the position correction of the heating unit has been performed in the first control mode in which the balance is detected by the balance detection unit 3 that detects the equilibrium state provided in the vicinity of the heating unit 2 and recognizes the signal. Thus, the position of the object to be heated 10 and the correction of the heating unit 2 can be corrected without using a drive part (not shown) that forcibly moves the position of the heating unit 2 of the first embodiment. In addition, it is not necessary for the user to delicately search for a position with good heating efficiency, and a user-friendly cooking device can be provided.

  The variable fixing portion 11 will be described with reference to FIGS. FIG. 3 is a configuration diagram showing the variable fixing portion 11. As shown in FIG. 3, it comprises a plurality of support racks 21 that support the heating unit 2 and springs 22 mounted around the support racks 21. The bottom shape of the support racks 21 is rounded, and the support racks 21 are The inner side 23 of the device to be attached is also formed in a round shape so that the support frame 21 can be moved. Further, FIG. 4 is a configuration diagram of the variable fixing unit 11 as viewed from above, and is a diagram illustrating an example of the arrangement of the plurality of support frames 21 that support the heating unit 2. As a result, the imbalanced state caused by the action of the magnetic lines of force between the object to be heated 10 and the heating unit 2 is limited by the movable range of each support frame 21 because there are a plurality of support frames 21. The movement will stop and be fixed at some point.

  In addition, although the variable fixing | fixed part 11 shall be located under the heating part 2, it is good also as a structure which provides the variable fixing | fixed part 11 directly under the top plate 9, and suspends the heating part 2. FIG.

  An example of the configuration of the balance degree detection unit 3 will be described with reference to FIG. In FIG. 5, the balance detection unit 3 is provided at the installation position 25 of the outer peripheral portion 24 of the heating unit 2. For the part for detecting the degree of balance, for example, if one or more reed switches are installed and a magnetic material such as a spherical permanent magnet is tilted within a certain range, the reed switch moves freely according to the tilt. With such a configuration, the reed switch is turned on and off, and the occurrence of tilt can be detected by the on and off signals. In addition, if a plurality of the above-described configurations are provided in the outer peripheral portion of the heating unit, it is possible to detect the inclination with higher accuracy. The same effect can be obtained by using a tilt sensor switch or the like instead.

  As described above, in the cooking device according to the present invention, if a pan or the like to be heated is placed at a position where approximate heating on the top surface of the top plate is possible, the heating unit moves to a position with good heating efficiency. In order to perform heating, it can be applied to applications such as stationary or built-in cooking devices that place a pan or the like on the top plate.
