(Embodiment 1)
FIG. 1 is a configuration diagram of an oven toaster according to the first embodiment of the present invention.

  In FIG. 1, a heating chamber 1 accommodates an object to be heated and cooks, and in the heating chamber 1, a heater 2, temperature detecting means 3 for detecting the temperature in the heating chamber 1, and the object to be heated are placed. A grill 6 is installed. The control means 4 measures the time from the end of the previous cooking to the time when the cooking start SW 7 is pressed until the cooking starts, and calculates the cooking time from the time and the temperature in the heating chamber at the start of cooking. decide. And when the determined heat cooking time passes, a heating will be stopped and heat cooking will be complete | finished. The heater energization stopping means 5 sends a signal to the control means 4 when cooking is performed after several times of continuous cooking and the temperature in the heating chamber 1 becomes high and exceeds the first predetermined temperature. The heater energization is temporarily stopped, and when the temperature in the heating chamber 1 decreases and falls below the second predetermined temperature, a signal is sent to the control means 4 to energize the heater again. Further, when the heater is temporarily stopped by the heater energization stopping unit 5, the control unit 4 is configured to increase the temperature in the heating chamber after the start of cooking, or after the start of cooking, even after the determined cooking time has elapsed. The heating cooking is extended according to the temperature rise state in the heating chamber and the temperature in the heating chamber at the start of cooking.

  About the oven toaster comprised as mentioned above, the operation | movement and an effect | action are demonstrated below, using FIG.

FIG. 2A shows a temperature change in the heating chamber 1 during cooking. FIG. 2B shows the heater operation according to the temperature change in the heating chamber 1. FIG. 2C shows the heater energization rate according to the temperature change in the heating chamber 1. When the cooking start SW 7 is pressed, the control means 4 receives the signal and starts energizing the heater. The cooking time is determined by the temperature θ0 in the heating chamber 1 at the start of cooking and the time TR from the end of the previous cooking to the start of current cooking. Generally, when the temperature in the heating chamber 1 at the start of cooking is the same, the longer the TR time, the longer the cooking time. Moreover, when TR time is the same, it determines so long that temperature (theta) 0 in the heating chamber 1 at the time of a heating cooking start is low. Let the cooking time determined here be T4. When the temperature in the heating chamber 1 reaches θ3 at T1 during cooking, the heater energization stop means 5 issues a heater energization stop signal to the control means 4 to stop the heater energization, and time elapses (TOFF). When the temperature in the heating chamber 1 decreases and reaches the temperature θ1, the heater is energized again (at time T2). The control means 4 measures the rising temperature θj (θ2-θ1) in the heating chamber 1 within the time Tj from the time T2 when the heater is energized again, determines the heating cooking extension time Tα according to the rising temperature θj, and T4 After the time, the heater is energized for Tα time to extend the cooking. As θj decreases, it can be determined that the capacity of the object to be heated is large or the ambient temperature is low, and the cooking time Tα becomes longer.

  As described above, in the present embodiment, the controller 4 detects the ambient temperature and the capacity of the object to be heated based on the rising temperature within a predetermined time when the heater is re-energized, and the time corresponding to the condition is detected. Because the cooking is extended from the determined cooking time only, the necessary heat capacity can be given to the heated object even if the difference in the capacity of the heated object or the difference in the ambient temperature at the time when the heater is re-energized, Cooking performance can be improved.

  Further, the controller 4 extends the cooking for a predetermined time from the determined cooking time by the heater energization rate corresponding to the temperature rise within the predetermined time when the heater is re-energized. By reducing the radiant heat and reducing the radiant heat, it is possible to prevent overheating of the object to be heated.

  In the above description, the time or the heater energization ratio according to the temperature rise within a predetermined time when the heater is re-energized is used. However, the combined effect can be obtained.

( Reference Example 1 )
The configuration of Reference Example 1 of the present invention is the same as that of the first embodiment.

Only the parts of the operation and action of the reference example 1 that are different from the first embodiment in FIG. 2 will be described.

  The control means 4 measures the time TON from the start of cooking (at time T0) until the heater energization is stopped (at time T1), and the heating cooking extension time from the TON time and the temperature θ0 in the heating chamber 1 at the start of cooking. Tα is determined, and the heater is energized for Tα time after T4 time to extend cooking. When the temperature θ0 in the heating chamber 1 at the start of cooking is the same, the longer the TON time, the larger the capacity of the article to be heated or the lower the ambient temperature, and the longer the cooking time extension Tα is set.

As described above, in this reference example , the control means 4 detects the ambient temperature and the capacity of the object to be heated based on the time from the start of cooking to the stop of the heater and the temperature in the heating chamber 1 at the start of cooking. However, since cooking is extended from the cooking time determined by the time according to the situation, the necessary heat capacity can be given to the heated object even if the capacity of the heated object is different or due to the ambient temperature. And cooking performance can be improved.

  Further, the controller 4 extends the cooking for a predetermined time from the determined cooking time by the heater energization rate corresponding to the time from the start of cooking to the stop of the heater and the temperature of the heating chamber at the start of cooking. By reducing the heater energization rate and suppressing the radiant heat, it is possible to prevent the object to be heated from being overly baked.

  The above is the time from the start of cooking to the stop of the heater and the time or the heater energization ratio according to the temperature of the heating chamber at the start of cooking, but the combined effect can also be obtained.

As described above, the oven toaster according to the present invention is capable of cooking even after the determined cooking time has elapsed when the temperature in the heating chamber becomes high during cooking and the energization of the heater is temporarily stopped. By providing a control means for extending the cooking time according to the temperature rise situation in the heating chamber after the start or the temperature rise situation in the heating chamber after the start of cooking and the temperature in the heating chamber at the start of cooking. It is possible to apply an amount of heat according to the ambient temperature and the capacity of the object to be heated, and it can be applied to an oven toaster or the like that improves cooking performance.
