FIG. 1 shows a configuration diagram of a heating cooker according to the first embodiment of the present invention.

  In FIG. 1, a heating cooker 10 according to the present invention includes an upper surface heating means 4 that heats the upper surface of the food 3 and a cooking dish 2 in a cooking chamber 1 that houses the food 3 placed on the cooking dish 2. A cooking dish heating means 5 for heating is provided, and a self-cleaning process 6 is performed on the side surface of the cooking chamber 1. In the first embodiment, the inside temperature detection means 7 in the cooking chamber 1, the cooking dish temperature detection means 8 that detects the temperature of the cooking dish 2, and the bottom temperature detection means 9 that detects the bottom temperature of the cooking chamber 1. Used a K-type thermocouple electrically insulated with an insulating material such as ceramics and coated with a metal such as stainless steel. The upper surface heating means 4 and the cooking dish heating means 5 are controlled by a cooking process program of a control means (not shown) according to the temperatures measured by the inside temperature detection means 7, the cooking dish temperature detection means 8 and the bottom temperature detection means 9. The

  About the cooking-by-heating machine 10 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

First, when cooking with the heating cooker 10, if a user pulls out a handle, the cooking dish 2 will slide out of the cooking chamber 1 in conjunction with it. Therefore, the cooked food 3 such as fish is placed on the cooking plate 2 and the handle is pushed and slid to be stored in the cooking chamber 1. Then, the 1st cooking process which heats the foodstuff 3 starts by operating the operation part which is not shown in figure. When the first cooking step is started, a step of energizing the upper surface heating unit 4 and the cooking pan heating unit 5 by a control unit (not shown) is performed. In this process, the temperature of the air in the cooking chamber 1 and the cooking pan 2 become higher according to the heating time, and the food 3 starts to be heated. Also, the temperature of the bottom surface increases with the heating time. And when the temperature of the cooking pan 2 reaches the upper limit temperature Ta, the second cooking step is started. In this step, the control means controls the cooking dish heating means 5 so that the temperature of the cooking dish 2 becomes Ta, and the upper surface heating means 4 continues to be energized. Since the air temperature in the cooking chamber 1 continues to rise, the food 3 is further heated. At this stage, oily smoke or the like starts to be generated from the food 3 and oil or the like begins to adhere to the side surface in the cooking chamber 1. And if the temperature in the cooking chamber 1 becomes upper limit temperature Tb, a 3rd cooking process will start. In this step, the control means controls the upper surface heating means 4 so that the temperature in the cooking chamber 1 becomes Tb, and controls the cooking dish heating means 5 so that the temperature of the cooking dish 2 becomes Ta. Object 3 is heated at a constant temperature. At this stage, the cooking 3 has already been cooked at a constant temperature, and oil smoke or the like is attached to the side surface of the cooking chamber 1, but the side temperature of the cooking chamber 1 has risen to near Tb, so that self The attached oil is decomposed due to the cleaning effect.

  When the cooking process is performed until the time of the cooking process reaches the predetermined time t1, the control unit ends energization of the upper surface heating unit 4 and the cooking pan heating unit 5 and ends the cooking process. The user can take out the cooked food 3 by pulling the handle out of the cooking chamber 1.

  The elapsed time of the cooking process is counted by a timer (not shown) connected to the control means.

  Thus, according to this Embodiment 1, in the process of cooking the foodstuff 3, the oil smoke etc. which generate | occur | produce from the foodstuff 3 always adhere to the side surface above the cooking plate 2 in the cooking chamber 1, There are parts where oily smoke sticks due to the high temperature, but by applying a self-cleaning treatment to the side, the temperature of the side rises with the cooking temperature at the same time as cooking, so even oil that is stuck can be easily decomposed. it can.

  Moreover, if the food 3 and the cooking pan 2 are removed and heated so that the temperature of the cooking chamber 1 is increased, the self-cleaning process applied to the side surface is maintained at a high temperature, and the oil adhered during cooking is decomposed. The cooking chamber 1 can be used continuously in a clean state not only in the initial stage but also in repeated use.

  Also, when the side surface of the cooking chamber reaches 200 ° C. or higher, it becomes difficult to wash the oil and the like, but at this time, if the side substrate is self-cleaning made of manganese oxide, The manganese oxide having an oil-decomposing action decomposes the oil adhering to the side surface, and the side surface of the cooking chamber can be continuously used in a clean state.

  Also, when the side of the cooking chamber reaches 200 ° C. or higher, it becomes difficult to clean with oil and the like. At this time, a self-cleaning process consisting of manganese oxide and cerium oxide is performed on the side substrate. If this is the case, manganese oxide, which has an oil-decomposing action, decomposes the oil adhering to the side surface, and cerium oxide supplies oxygen necessary for oil decomposition, so the side of the cooking chamber is kept clean and used continuously. can do.

  In addition, when the side surface of the cooking chamber reaches 250 ° C. or higher, corrosive compounds such as salt adhere to the part where oil or the like is stuck, but at this time, the base material has corrosion resistance such as stainless steel or aluminum steel plate. If a high base material is used, even if a corrosive compound adheres, corrosion of the base material can be suppressed.

  In addition, when the side surface of the cooking chamber becomes 200 ° C. or higher, it becomes difficult to wash the oil and the like, but at this time, the side surface of the cooking chamber is treated with soot containing manganese oxide as a self-cleaning process. If the side temperature of the cooking chamber is up to 400 ° C., manganese oil having an oil-decomposing action is decomposed in the sticking oil or the like, and the side of the cooking chamber can be continuously used in a clean state. .

In addition, when the side surface of the cooking chamber becomes 200 ° C. or higher, it becomes difficult to wash the oil and the like, but at this time, the side surface of the cooking chamber contains manganese oxide and cerium oxide as a self-cleaning process. If the side temperature of the cooking chamber is up to 400 ° C, the sticky oil etc. will decompose the manganese oxide which has oil-decomposing action, and cerium oxide will supply the oxygen necessary for the oil decomposition Therefore, the side surface of the cooking chamber can be continuously used in a clean state.

  In addition, you may mount the heating cooker of this Embodiment in an electromagnetic induction heating type cooking device.
