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

  When a user cooks a food such as meat or fish using the cooking chamber 3, the user places a food such as meat or fish on the heated object H2 such as a grill plate and cooks the food. Is placed in the cooking cabinet 3. At this time, in a state where the opening 3a of the cooking cabinet body 3b is closed by the door 3c, the user pulls the door 3c covering the opening 3a of the cooking cabinet body 3b forward, that is, to the user side. Thus, the door 3c slides forward together with the rail 3d, and the opening 3a of the cooking cabinet body 3b is opened. Then, a user throws in the to-be-heated material H2 by which the foodstuff was mounted in the cooking chamber main body 3b from the opening part 3a of the cooking chamber main body 3b, pushes down the door part 3c back, and opens the cooking chamber main body 3b. By closing the part 3a with the door part 3c, the cooker 3 can be used to cook food such as meat and fish.

In the state where the heated object H2 containing the cooking such as meat and fish is placed in the cooking chamber 3,
A user operates the selection part 6 and selects the heating conditions for cooking the food on the to-be-heated material H2 in the cooking chamber 3. FIG. Here, in this Embodiment, the case where a user selects the 1st cooking course as a heating condition for cooking the cooking on the to-be-heated material H2 in the cooking chamber 3 is demonstrated. Moreover, as a 1st cooking course, the preheating process of performing the preheating of the to-be-heated object H2 mounted in the cooking chamber 3, and the to-be-heated object H2 on which the cooked material is mounted are executed after the preheating process. A load amount determination step for determining the load amount, a cooking step that is executed after the load amount determination step, and a smoke removal step that is executed after the cooking step are provided.

  As shown in FIG.6 and FIG.7, in the state in which the to-be-heated material H2 which accommodated cooking items, such as meat and fish, was mounted in the cooking chamber 3, a user is on the to-be-heated material H2 in the cooking chamber 3. When the first cooking course is selected as the cooking course for cooking the cooked food, the first control means 8 controls the second heating coil 4 and the heater 5 based on the first cooking course.

  The 1st control means 8 determines the thermal power of the 2nd heating coil 4 in the preheating process of a 1st cooking course based on the power consumption of the heating cooker 100, and performs the preheating process of a 1st cooking course doing.

  As shown in FIG. 6, for example, when the maximum power consumption of the heating cooker 100 is 5800 W, the first control means 8 is a preheating step of the first cooking course in the preheating step of the first cooking course. The maximum heating power in the second heating coil 4 is set to the maximum heating power (for example, 2500 W), and the second heating coil 4 is continuously operated for a predetermined time (for example, 60 seconds) with the maximum heating power of the second heating coil 4. Then, the object to be heated H2 is preheated. After that, the first control means 8 reduces the heating power to be smaller than the maximum heating power of the second heating coil 4 (for example, 2000 W), and the heating power to be smaller than the maximum heating power of the second heating coil 4 (for example, 2000 W). Then, the second heating coil 4 is continuously operated for a predetermined time.

  Thereby, the temperature of the to-be-heated object H2 mounted in the cooking chamber 3 is necessary for cooking the cooking object regardless of the load amount of the to-be-heated object H2 on which the cooking object in the cooking chamber 3 is mounted. The temperature can be quickly raised to a certain temperature, and the cooking time of the first cooking course can be shortened.

  Here, as the object to be heated H2 placed in the cooking chamber 3, a grill pan or the like whose surface is coated with fluorine or the like is used. When a grill pan whose surface is coated with fluorine or the like is used as the object to be heated H2, if the temperature of the grill pan exceeds 250 degrees, the performance of the fluorine applied to the surface of the grill pan will deteriorate. There is a case.

  So, in this Embodiment, in the preheating process of a 1st cooking course, the 1st control means 8 cooks irrespective of the some load amount of the to-be-heated material H2 mounted in the cooking chamber 3. The 2nd heating coil 4 and the heater 5 are controlled so that the temperature of the to-be-heated object H2 mounted in the store | warehouse | chamber 3 may be 250 degrees or less.

  Thereby, in the preheating process of a 1st cooking course, it can fully prevent that the temperature of to-be-heated material H2, such as a grill plate, rises excessively and the performance of to-be-heated material H2 deteriorates. it can.

  Further, as a method of detecting the temperature of the object to be heated H2, the temperature of the object to be heated H2 may be directly detected by a temperature sensor (not shown), or from the heat capacity or power consumption of the object to be heated H2. You may calculate the temperature of the to-be-heated material H2.

In the present embodiment, the first control means 8 operates the second heating coil 4 for 60 seconds at 2500 W which is the maximum heating power of the second heating coil 4 in the preheating step of the first cooking course. Thereafter, the second heating coil 4 is operated for a predetermined time at 2000 W, which is a thermal power smaller than the maximum thermal power of the second heating coil 4. And in this Embodiment, temperature sensors (not shown), such as a thermistor, are arrange | positioned at the exhaust pipe (not shown) which exhausts the smoke etc. in the cooking cabinet 3 to the exterior of the cooking cabinet 3, and a temperature sensor ( When the temperature detected in the not-shown temperature is equal to or higher than a predetermined temperature (for example, 90 degrees when the food placed on the object to be heated H2 is fish), the first control means 8 The preheating process of 1 cooking course is complete | finished, and it is comprised so that the load amount determination process of a 1st cooking course may be performed. Moreover, in this Embodiment, even if it is a case where the temperature detected with the temperature sensor (not shown) has not reached predetermined temperature in the preheating process of a 1st cooking course, it is the 2nd heating coil 4. When the total time of the time for which the second heating coil 4 is operated at 2000 W, which is a heating power smaller than the maximum heating power, exceeds 3 minutes, The first control means 8 is configured to end the preheating process of the first cooking course and execute the load amount determination process of the first cooking course. Here, as the temperature at which the preheating process of the first cooking course is finished and the process proceeds to the load amount determination process of the first cooking course, the temperature of the article to be heated H2 may be shifted at a temperature not exceeding 250 degrees. When the temperature is suitable for cooking the food placed on the object to be heated H2, the preheating process of the first cooking course is finished, and the process proceeds to the load amount determination process of the first cooking course. That's fine.

  Thereby, in the preheating process of a 1st cooking course, it can fully prevent that the temperature of to-be-heated material H2, such as a grill plate, rises excessively and the performance of to-be-heated material H2 deteriorates. it can.

  Here, in general, the maximum power consumption of the cooking device that induction-heats the object to be heated is 5800 W. However, in the user's usage environment, 5800 W may not be used as the maximum power consumption of the cooking device. . Therefore, the cooking device of the present embodiment is configured such that the maximum power consumption of the cooking device can be used as power consumption (for example, 4800 W) smaller than 5800 W.

  As shown in FIG. 7, for example, when the power consumption of the heating cooker 100 is used as power consumption (for example, 4800 W) smaller than 5800 W, which is the maximum power consumption of the heating cooker 100, the first control unit 8 is In the preheating process of the first cooking course, the maximum heating power of the second heating coil 4 in the preheating process of the first cooking course is smaller than the maximum heating power (for example, 2500 W) of the second heating coil 4 (for example, 2500 W). , 2000 W), the second heating coil 4 is continuously operated for a predetermined time at a heating power (for example, 2000 W) smaller than the maximum heating power of the second heating coil 4 to preheat the object to be heated H2.

  Here, as in the case where the maximum power consumption of the heating cooker 100 shown in FIG. 6 is 5800 W, in the present embodiment, detection is performed by a temperature sensor (not shown) disposed in the exhaust pipe (not shown). The first control means 8 preheats the first cooking course when the applied temperature becomes equal to or higher than a predetermined temperature (for example, 90 degrees when the food placed on the object to be heated H2 is fish). It is comprised so that a process may be complete | finished and the load amount determination process of a 1st cooking course may be performed. Moreover, in this Embodiment, even if it is a case where the temperature detected with the temperature sensor (not shown) has not reached predetermined temperature in the preheating process of a 1st cooking course, it is the 2nd heating coil 4. When the time during which the power is operated at 2000 W exceeds 3 minutes, the first control means 8 ends the preheating process of the first cooking course and executes the load amount determination process of the first cooking course. It is configured as follows.

As shown in FIG.6 and FIG.7, the 1st control means 8 is temperature suitable for the temperature of the to-be-heated material H2 mounted in the cooking chamber 3 to cook the cooking material on the to-be-heated material H2. When the temperature reaches (for example, 90 degrees in the case of grilled fish), the preheating process of the first cooking course is terminated, and the load amount determination process of the first cooking course is executed. In the load amount determination step, the first control means 8 detects the temperature of a temperature sensor (not shown) such as a thermistor disposed in the exhaust pipe (not shown), and the temperature is set to a predetermined temperature ( For example, the load amount of the object to be heated H2 on which the food item is placed is determined from the time rising from 90 degrees to 160 degrees), and cooking is performed with the optimum heating power and cooking time according to the load amount in the subsequent process. Thus, the second heating coil 4 and the heater 5 are controlled.

  Here, during the execution of the first cooking course, the user performs cooking using the first heating area W1, and thus the heated object H1 in which the food is accommodated is placed in the first heating area W1. After that, the selection unit 6 may be operated to select the heating condition of the first heating coil 2 corresponding to the first heating region W1.

  In the present embodiment, the first control coil 8 controls the first heating coil 2 and the second heating coil 4 corresponding to the first heating region W1, and the first control module 8 While the preheating step of the first cooking course is being performed, the selection of the heating condition of the first heating coil 2 corresponding to the first heating region W1 is not accepted. That is, in this Embodiment, the 1st control means 8 is comprised so that only the 2nd heating coil 4 may be controlled, while the preheating process of a 1st cooking course is performed. Thereby, in the preheating process of a 1st cooking course, the thermal power of the 2nd heating coil 4 can fully be ensured, and the usability of the heating cooker 100 can be improved. At this time, you may make it display on the display part (not shown) of the selection part 6 that the 1st heating coil 2 corresponding to the 1st heating area | region W1 cannot be used. Accordingly, it is possible to notify the user that the first heating coil 2 corresponding to the first heating region W1 cannot be used during the preheating process of the first cooking course, and the usability of the heating cooker 100 is improved. Can be improved.

  Moreover, in this Embodiment, the 1st control means 8 is while the process after the preheating process of a 1st cooking course, ie, the process after the load amount determination process of a 1st cooking course, is performed. The first heating coil 2 can be operated with a heating power smaller than the difference between the maximum heating power of the second heating coil 4 in the load amount determination step and the heating power of the second heating coil 4 in the process being executed. It is configured as follows.

  That is, as shown in FIGS. 6 and 7, for example, in the load amount determination process of the first cooking course, the maximum heating power is set to 1500 W, and the second heating coil 4 is operated. In a state where the load amount determination process of the first cooking course is executed with the maximum heating power 1500 W of the second heating coil 4, the user uses the first heating area W 1 to perform cooking, so the cooked material is accommodated. When the heated object H1 is placed on the first heating region W1 and the heating condition of the first heating coil 2 corresponding to the first heating region W1 is selected by the selection unit 6, the first control is performed. The means 8 is 1500 W that is the maximum heating power of the second heating coil 4 in the load amount determination step of the first cooking course, and a heating power that is smaller than the heating power of the second heating coil 4 in the load amount determination step that is being executed. Thus, the first heating coil 2 corresponding to the first heating region W1 is controlled to operate.

That is, in the load amount determination step of the first cooking course, the first control means 8 sets the maximum heating power of the second heating coil 4 to 1500 W, and sets the second heating coil 4 to 7 seconds in a 16-second cycle. Duty control to turn on is performed. In this case, the heating power of the second heating coil 4 in the load amount determination step being executed is 1500 W × 7/16, and the heating power of the second heating coil 4 in the load amount determination step being executed is about 656 W. The first control means 8 corresponds to the first heating region W1 when operating the first heating coil 2 corresponding to the first heating region W1 during the execution of the load amount determination step of the first cooking course. The heating power of the second heating coil 4 in the load amount determining step being executed is reduced from 1500 W, which is the maximum heating power of the second heating coil 4, to the heating power obtained by subtracting about 656 W. The first heating coil 2 corresponding to the first heating region W1 is controlled such that the output of one heating coil 2 is smaller than 1500W−656W = 844W. The first heating coil 2 corresponding to the first heating region W1 is duty-controlled so that the first heating coil 2 is turned on for 8 seconds at a maximum heating power of 1500 W, and the average heating power is 750 W. Here, the first heating coil corresponding to the operating time of the second heating coil 4 in the load amount determination step of the first cooking course and the first heating region W1 in the load amount determination step of the first cooking course The difference from the operation time of 2, that is, 1 second is ensured as a switching time of the inverter (not shown).

  In the present embodiment, during the execution of the load amount determination step of the first cooking course, the user uses the first heating region W1 to cook and the heated object in which the food is stored is stored. The case where the object H1 is placed on the first heating region W1 and the heating condition of the first heating coil 2 corresponding to the first heating region W1 is selected by the selection unit 6 has been described. In order for the user to cook using the first heating area W1 during the cooking process of the cooking course, the object to be heated H1 containing the food is placed in the first heating area W1 and selected. In the case where the heating condition of the first heating coil 2 corresponding to the first heating region W1 is selected in the part 6, the first is the same as during the execution of the load amount determination process of the first cooking course described above. By controlling the heating power of the first heating coil 2 corresponding to the heating area W1, the first heating It is possible to operate the coil 2.

(Embodiment 2)
Embodiment 2 of the heating cooker of this invention is demonstrated using FIG. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 8 is a diagram showing a change in output of the second heating coil and a change in temperature in the cooking chamber when the second cooking course in the second embodiment of the present invention is executed.

  In addition, the 2nd cooking course in this Embodiment is when the 1st heating coil 2 corresponding to the 1st heating area W1 is operated before the 2nd heating coil 4 is operated. The cooking course to be selected.

  In a state where the first heating coil 2 corresponding to the first heating region W1 is operated and cooking in the first heating region W1 is being performed, the user performs cooking using the cooking chamber 3, There is a case where the object to be heated H2 in which the food is accommodated is placed in the cooking cabinet 3, and then the selection unit 6 is operated to select the heating condition of the second heating coil 4. In this case, since the operation of the first heating coil 2 corresponding to the first heating region W1 cannot be stopped, in the preheating step of preheating the cooking chamber 3, the second heating coil 4 is made with the maximum heating power. It cannot be operated.

  Therefore, in the present embodiment, the user performs cooking using the cooking chamber 3 while the first heating coil 2 corresponding to the first heating region W1 is in operation, so that the food in which the food is stored is stored. When the heated object H2 is placed in the cooking chamber 3, and the heating condition of the second heating coil 4 is selected by the selection unit 6, the first control means 8 is based on the second cooking course, The heating coil 2 and the second heating coil 4 are controlled. That is, in the second cooking course, the first control means 8 is configured such that the heating power of the first heating coil 2 is the maximum heating power of the second heating coil 4 and the second heating coil in the preheating process of the second cooking course. The thermal power of the first heating coil 2 is controlled so that the thermal power is smaller than the difference from the thermal power.

Specifically, in the preheating process of the second cooking course, the first control means 8 is configured so that the heating power of the second heating coil 4 is smaller than the maximum heating power (for example, 2500 W) of the second heating coil 4. The second heating coil 4 is controlled to be (for example, 1500 W). At this time,
Since the second heating coil 4 is to be used, the first control means 8 causes the first heating coil 2 corresponding to the first heating region W1 to be at 1500 W for 8 seconds in a 16-second cycle. The duty control is set to the on state, the heating power of the first heating coil 2 corresponding to the first heating region W1 is set to 750 W, and the second heating coil 4 is turned on at 1500 W for 7 seconds in a 16-second cycle. The duty control is set to the state, and the heating power of the second heating coil 4 is set to 656 W on average. In the preheating process of the second cooking course, the temperature detected by the temperature sensor (not shown) arranged in the exhaust pipe (not shown) is the temperature detected in the preheating process of the first cooking course ( For example, when a temperature lower than 90 degrees (for example, 75 degrees) is reached, the preheating process of the second cooking course is terminated, and the process proceeds to the load amount determination process of the second cooking course. In the load amount determination step of the second cooking course, the temperature detected by a temperature sensor (not shown) such as a thermistor disposed in the exhaust pipe (not shown) is a predetermined temperature (for example, from 75 degrees). The load amount of the object to be heated H2 on which the food item is placed is determined based on the time to rise to 140 degrees. In addition, in the 2nd cooking course, since the thermal power of the preheating process of cooking using the cooking chamber 3 becomes smaller than the thermal power of the preheating process of the 1st cooking course, cooking time becomes long compared with the 1st cooking course. However, cooking using the cooking chamber 3 becomes possible.
