For example, in the case of cooking that may spill at constant heating power, such as reheating warm soup and miso soup with ingredients, but there is a possibility that bumping may occur at high heating power if the difference in heating power level is too large 2, the heating mode is selected from the menu key 6 a by the operation unit 6 shown in FIG. 2, the heating is started by the start key 6 b, an arbitrary heating power is selected by the heating power selection key 6 c, and the heating output pattern selection key 6 d is used for FIG. As shown in the above, the output of the inverter is set to P3 for a predetermined time T3, the output of the inverter is set to P4 different from P3 for the predetermined time T4, and the cooking is performed by selecting and heating the heating output pattern that is periodically repeated. Good convection occurs in the inside, and it is possible to cook with good workmanship without warming unevenness.

  As described above, in the present embodiment, one of the heating output patterns is set such that the output of the inverter is P3 for a predetermined time T3, and the output of the inverter is P4 different from P3 for the predetermined time T4. By using a heating output pattern that repeats periodically, convection is unlikely to occur in the pan with constant heating as shown in FIG. 3, such as reheating of ingredients, soup with less thickness, and miso soup, as shown in FIG. In the case of cooking in which bumping may occur when P2 and OFF are repeated, moderate convection occurs in the pan by periodically repeating P3 and P4 different from P3, and a favorable workmanship cooking can be performed. .

(Embodiment 5)
FIG. 1: shows the schematic block diagram of the induction heating cooking appliance in the 5th Embodiment of this invention, and a structure is the same as Embodiment 1-4.

  About the induction heating cooking appliance comprised as mentioned above, operation | movement and an effect | action are demonstrated, referring FIG. FIG. 2 is a configuration diagram of the operation unit 6 of the induction heating cooker according to the fifth embodiment of the present invention, and FIG. 6 is a heating output pattern diagram of the induction heating cooker according to the fifth embodiment of the present invention. is there.

  First, when the user places the pan 1 containing the food to be cooked on the top plate 2 and selects one of the set heating power and two or more heating output patterns with the operation unit 6, the control means 5 A high frequency current is supplied from the inverter 4 to the heating coil 3 according to the command, and heating is performed with the set thermal power and heating output pattern.

  For example, when cooking stew, stir ingredients such as meat and vegetables, add water, simmer until the ingredients become soft to some extent, add white sauce and heat until thickened.

  In the case of such cooking, the process of frying meat and vegetables requires a certain amount of heat, the subsequent stew process requires moderate convection, and the white sauce is added to the thickening stage without scorching. Although it is necessary to cause convection, the output pattern can be changed during heating. First, the heating mode is selected from the menu key 6a with the operation unit 6 shown in FIG. 2, and heating is started with the start key 6b. An arbitrary heating power is selected with the heating power selection key 6c, and the key 11 is selected with the heating output pattern selection key 6d to continuously output a predetermined heating power P5 as shown in FIG. After boiling and adding water, the key 13 is selected with the heating output pattern selection key 6d, the output of the inverter is set to P6 for a predetermined time T5, and the output of the inverter is set to P6 for a predetermined time T6. P7, boil until the material becomes soft to some extent while causing moderate convection in the heating output pattern that repeats periodically, add white sauce, then select key 12 with the heating output pattern selection key 6d The output of the inverter is set to P8 for a predetermined time T7, the output of the inverter is turned off for a predetermined time T8, and a moderate convection is caused in the pan so that the bottom of the pan does not burn with a heating output pattern that is periodically repeated. The user can cook while changing the heating output pattern as appropriate while watching the completed state according to the cooking process, such as further heating until thickening.

  Furthermore, when it is desired to change the set heating power, cooking can be performed while selecting an arbitrary heating power with the heating power selection key 6c and selecting an appropriate heating output pattern with the heating output pattern selection key 6d.

  As described above, in the present embodiment, by setting the output pattern to be changeable during heating, when it is desired to cook with a different heating output pattern at each cooking stage, the heating power is turned off and the setting thermal power is set again. It is not necessary to reset the heating output pattern, and cooking can be performed smoothly. In addition, by adopting a configuration that can be changed to other set heating power, cooking with a favorable workmanship can be performed more flexibly.

(Embodiment 6)
FIG. 1: shows the schematic block diagram of the induction heating cooking appliance in the 6th Embodiment of this invention, and a structure is the same as Embodiment 1-5.

  About the induction heating cooking appliance comprised as mentioned above, operation | movement and an effect | action are demonstrated, referring FIGS. FIG. 2 is a configuration diagram of the operation unit 6 of the induction heating cooker according to the sixth embodiment of the present invention, and FIGS. 3 to 4 are heating output patterns of the induction heating cooker according to the sixth embodiment of the present invention. FIG.

  First, when the user places the pan 1 containing the food to be cooked on the top plate 2 and selects one of the set heating power and two or more heating output patterns with the operation unit 6, the control means 5 A high frequency current is supplied from the inverter 4 to the heating coil 3 according to the command, and heating is performed with the set thermal power and heating output pattern.

  For example, when baking a hot cake, a stable constant heating power is preferable in order to give a moderate baking color to the surface and make the finish plump, so select the heating mode from the menu key 6a on the operation unit 6 shown in FIG. Then, after heating is started with the start key 6b, an arbitrary heating power is selected with the heating power selection key 6c, the key 11 is selected with the heating output pattern selection key 6d, and a predetermined heating power P1 as shown in FIG. By cooking with the heating output pattern to be output, it can be finished to the optimum workmanship. However, if the heating output pattern is selected incorrectly, the key 12 is selected with the heating output pattern selection key 6d, and the result is shown in FIG. In such a heating time pattern, the output of the inverter is set to P2 for a predetermined time T1, the output of the inverter is turned off for a predetermined time T2, and this is periodically repeated. If the process is performed, the high heating power P2 is output during the predetermined time T1, so that the color may become brighter than the case of cooking with the heating output pattern of FIG. There is no problem if cooking while looking at the image, and the average output of the inverter is the same as in FIGS. 3 and 4, so that the workmanship is not greatly impaired.

  As described above, in the present embodiment, the induction heating cooker that makes the average output of the inverter the same regardless of the type of heating output pattern at the same set heating power, and thus the user This not only has the merit that it is easy to imagine the workmanship for each set thermal power, but even if the wrong heating output pattern is selected, the workmanship is not greatly impaired and cooking can be done with peace of mind.

  As described above, the induction heating cooker according to the present invention has two or more heating output patterns that repeat continuously or periodically for at least one set thermal power, and selects a heating output according to the type of cooking. By adopting such a configuration, it is possible to realize the optimum workmanship according to the cooking menu and finish preference, which is effective for the application of a heating cooker.
