  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment)
The figure exemplifies an induction heating cooker as the heating cooker in the embodiment of the present invention.

  As shown in FIG. 1, the heating cooker in the present embodiment includes a cooker body 1 and a stirrer body 2 that is detachably provided on the cooker body 1.

  The cooker body 1 is provided with a top plate 3 for placing a heating vessel 13 containing an object to be heated on its upper surface, and a heating coil for induction heating the heating vessel 13 below the top plate 3. The three heating means 4, the control means 5 for controlling the output of the heating means 4, the storage means 6 for storing a heating program preset for each cooking menu, and the control means 5 and the storage means 6 are cooled. It has a blower 7 and is housed in a case 8. On the front surface of the case 8, a power switch 9 for turning on / off the power, an operation means 10 for setting the output and cooking menu, an output display means 11 for displaying the cooking menu and output setting, and a start for starting heating A button 12 is provided.

  The top plate 3 has a heatable region such as a circle indicating the inside of the heating region for placing the heating container 13 at a position where the heating means 4 is disposed. 14a is provided and is electrically connected to the connection terminal portion 14b of the stirrer body 2. The connection terminal portion 14a is formed with a recess so that when the stirrer body 2 is not connected, it is closed with a cover (not shown) to prevent electric shock.

  The stirrer body 2 has a motor 16 that is controlled and driven by the control means 5 of the cooker body 1 in the casing 15, and a support shaft 17 is connected to the motor 16. An agitation means 19 for agitating an object to be heated in the heating container 13 is detachably attached to the tip of the support shaft 17 via a connecting portion 18. The stirring means 19 is made of a heat-resistant plastic or ceramic. For example, silicon or the like can be deformed to some extent, so that it is suitable for stirring a solid object to be heated. In addition, about three different sizes are designed and prepared. For example, if it is designed to have a diameter of 10, 15 and 24 cm as a diameter at the time of rotation, by replacing the stirring means 19, a medium-sized pan around 20 cm in diameter from a small pan with a diameter of about 14 cm like a milk pan, Furthermore, it becomes possible to handle large pots with a diameter of 25 cm or more. Moreover, about the shape of the stirring means 19, it shall consist of two blades or one blade. As shown in FIG. 2, the connecting portion 18 may be configured to be tightened with a screw, or may be configured to have a protrusion for fixing from the inside of the support shaft 17 by insertion of the stirring means 19.

  Furthermore, the tip end portion of the support shaft 17 is provided with a temperature detection means 20 that comes into contact with an object to be heated and measures the temperature directly. The temperature detecting means 20 and the stirring means 19 are disposed so as to maintain a distance that prevents both of them from contacting even if the stirring means 19 rotates. Since the temperature detection means 20 is located above the stirring means 19, the temperature in the vicinity of the stirring means 19 can be detected, and an electrical signal of the detected temperature is connected between the connection terminal portion 14 b on the housing 15 side and the top plate 3. When the terminal portion 14a is connected, it is sent to the control means 5.

  As shown in FIG. 3, the connection terminal portion 14 b of the housing 15 has a convex shape, and two fixing plates 21 are provided on the side surface of the housing 15, and the connection terminal portion 14 a of the top plate 3. When the connection terminal portion 14b of the housing 15 is inserted and connected to the fixed plate 21, the stirrer body 2 is installed in a stable state because the fixing plate 21 is placed on the top plate 3. The casing 15 is provided with a height switching means 22, and the upper part of the casing 15 in which the motor 16 is built is variable by a certain distance in the vertical direction with the height switching means 22 as a boundary. The height of 19 can be changed. It should be noted that the distance at which the upper portion of the casing 15 can be pulled up is constant and cannot be pulled out.

  With the above configuration, the heating cooker performs cooking by controlling the output of the heating means 4 and the operation of the stirring means 19 based on the temperature value detected by the temperature detection means 20 of the stirrer body 2. It is.

  The operation of the cooking device configured as described above will be described. In addition, since the principle etc. of induction heating of an induction heating cooking appliance are well-known, description is abbreviate | omitted here.

  First, an object to be heated is placed in a heating container 13 capable of induction heating and placed in a range such as a circle drawn on the heating means 4 (heatable region). Next, the connection terminal portion 14 b of the stirrer body 2 equipped with the stirring means 19 suitable for the size of the heating container 13 to be used is inserted and connected to the connection terminal portion 14 a of the concave portion of the top plate 3. When the upper portion of the casing 15 is pushed downward by the height switching means 22, the stirring means 19 is positioned at a height that does not contact the bottom surface of the heating container 13, and the temperature detection means 20 is also placed inside the object to be heated. To position. Thereafter, the power switch 9 is turned on, the menu is selected by the operating means 10, and the start button 12 is pressed to start heating.

  For example, when automatic cooking that warms a highly viscous menu such as corn soup is selected, the stirring means 19 rotates from the start of heating, and the temperature of the heating means 4 is reached when the temperature value detected by the temperature detecting means 20 reaches 70 ° C. A heating program that weakens the output is stored in the storage means 6 in advance. In the initial stage of heating, the heating means 4 must be controlled at a high output in order to raise the temperature of the object to be heated, but convection is unlikely to occur in thick and thick menus such as corn soup, potage, and simmering. For this reason, the portion in contact with the heating means 4 on the bottom surface of the heating container 13 becomes hot immediately after the start of heating and easily burns. For this reason, the heating program is set so that the bottom surface of the heating container 13 is stirred by the stirring means 19 from the beginning of heating. As a result, it is possible to efficiently raise the temperature of the object to be heated with high heating power while suppressing scorching.

  In accordance with such a heating program, the motor 16 is driven by the control means 5 from the start of heating, and the stirring means 19 rotates 180 ° C. and then reversely rotates 180 ° C. to stir the object to be heated. By such a rotation method, a metal wire such as a thermocouple built in as the temperature detecting means 20 is prevented from being entangled in the housing 15. As the heating proceeds, the temperature value of the temperature detecting means 20 rises, but each time the temperature rises by 10 ° C., the rotational speed of the stirring means 19 is controlled to increase stepwise. By doing so, it is possible to prevent scorching that tends to occur as the temperature rises. When the heating further proceeds and the detected temperature value of the temperature detection means 20 reaches 70 ° C., the control means 5 reduces the output of the heating means 4 from, for example, 800 W to 300 W. Thereafter, when the temperature value of the temperature detecting means 20 reaches 95 ° C., the output of the heating means 4 and the driving of the motor 16 are stopped. The induction heating of the heating container 13 and the rotation of the stirring means 19 are stopped, and the end of cooking is notified by voice. Alternatively, the end sound may be used.

  In addition, when a menu such as boiled beans, curry or stew is selected, if the stirring means 19 continues to rotate, the ingredients tend to touch the stirring means 19 and cause crushing, and the beans etc. will peel off and will be intermittent. Thus, the stirring means 19 is controlled to rotate. For example, in curry, when the temperature reaches 95 ° C., the control means 5 reduces the output of the heating means 4 from, for example, 800 W to 300 W. In that state, after 20 minutes have passed, the introduction of a commercially available carousel is notified by voice, the motor 16 is driven, and the stirring means 19 is controlled to rotate 360 degrees in a low speed of 60 seconds. Thereafter, the control means 5 stops the motor 16 for 15 seconds and drives it again for 60 seconds to rotate the stirring means 19 360 degrees in the opposite direction to the previous one. The driving and stopping of the motor 16 are repeated until the heating is completed.

  In addition, since there is no risk of scorching in a menu that has a large amount of food such as potov, a lot of liquid, and sufficient convection, the stirring means 19 is not necessary. At that time, only the stirring means 19 is removed from the support shaft 17, and only the support shaft 17 provided with the temperature detection means 20 is inserted into the object to be heated, and the temperature is detected, and the heating program is performed based on the temperature value. The output of the heating unit 4 may be controlled by the control unit 5.

  After the cooking using the stirring means 19 is completed, the casing 15 can be pulled upward while pushing the height switching means 22 and the stirring means 19 can be removed from the support shaft 17 for cleaning. Moreover, if the whole housing | casing 15 is removed from the top plate 3 and the connection terminal part 14a of the top plate 3 is covered, it can return to a flat state, and it is easy to care for wiping off dirt etc. Can be maintained.

  If the heat retention menu is selected after the heating is completed, the stirring means 19 operates to stir the object to be heated when a certain time has elapsed after the heating is completed, for example, 1 minute after the cooking is completed. Immediately after the heating is finished, the heated object is kept at a high temperature by the residual heat of the heating container 13 and the top plate 3 and is easily burnt. Therefore, after the heating is completed, the object to be heated can be stirred by the stirring means 19 to prevent scorching due to residual heat.

  Further, in the present embodiment, the upper part of the casing 15 in which the motor 16 is built is variable by a certain distance in the vertical direction with the height switching means 22 as a boundary. However, as shown in FIG. A configuration in which the upper portion of the body 15 rotates 90 degrees upward with the hinge portion 23 as a fulcrum may be added. In this configuration, by rotating 90 degrees upward after changing the height of the upper portion of the casing 15, the support shaft 17 moves in the horizontal direction, so that the agitation means 19 can be easily attached and detached.

  In the present embodiment, the heating means 4 composed of heating coils is arranged at three locations. However, one of the three locations may be configured as a radial heater, and a stirrer is also used in heating by the radial heater. By attaching the main body 2, the above-described effects can be obtained. The heating means 4 is not limited to a heating coil or a radiant heater, but may be a gas or a sheathed heater that is another heat source.

  As described above, the heating cooker according to the present invention can be automatically cooked without scorching the object to be heated, so of course as an induction heating cooker, a heating cooker using other heat sources, etc. It may be applicable to general cooking devices.
