Description

  The present invention relates to a heating apparatus having a function of placing a food item on a heating pan and baking it.

  In the conventional heating device, when cooking continuously, the temperature in the heating chamber becomes higher than the first time from the start of cooking, and if the cooking time is the same as the first time, the finished state will be different. The difference increases as the number of consecutive times increases. In particular, when baking bread repeatedly, it is considered that there are many opportunities for continuous cooking without lowering the temperature in the heating chamber. On the other hand, there are some which control the cooling means and the heat generating member in accordance with the temperature in the heating chamber to suppress the temperature increase in the heating chamber (see, for example, Patent Document 1).

  However, when a food item is placed on a heating pan and baked, the food item is affected by the temperature of the heating plate as well as the temperature in the heating chamber. After running a cooking menu that uses a heated dish, the user typically rinses the heated dish. However, when a heat-resistant dish containing bread or food is placed on a heating dish and baked, there is a high possibility that the heating dish will not be washed because it is not soiled. If the tone menu is executed continuously without washing the heating dish, the second and subsequent cooking will be performed with the temperature of the heating dish being high. If it is a so-called manual menu where the user sets the time and heats, the user can adjust the heating time, but in the so-called automatic menu where the time cannot be set, the surface temperature of the heating dish cannot be detected by the conventional method. Even if the temperature in the heating chamber is lowered, there is a problem that if the cooking is continuously performed while the temperature of the heating dish is high, the baking color becomes dark.

  The present invention solves the above-mentioned conventional problems, and is a heating apparatus that can obtain a good baking condition even when baked continuously, particularly when baking a pan on a heating pan. The purpose is to provide.

  The heating device of the present invention that solves the above problems includes a heating chamber that heats an object to be heated, a heating dish that can be attached to and detached from the heating chamber, and a heating unit that heats the object to be heated placed on the heating dish. And a temperature detecting means for detecting the temperature in the heating chamber, a control means for determining the heating time and controlling the heating means, and a time measuring means for measuring the time. When it is detected that the temperature in the heating chamber is high, the heating time for high-temperature heating is determined, and even when the temperature in the heating chamber at the start of heating is low, the elapsed time from the end of the cooking menu using the heating pan The time is measured, and when the same cooking menu is repeated, the heating time is determined according to the elapsed time.

  In addition, it is possible to measure the elapsed time from the end of the cooking menu using the heating dish and to determine the heating time according to the elapsed time even when different menus using the same heating dish are continued. Good.

As a result, even when the surface temperature of the heating pan is high, the corresponding heating time can be determined.
Good baking is obtained even with continuous cooking.

  As is apparent from the above description, according to the heating device of the present invention, when baking bread continuously, the heating time is determined by the elapsed time from the end of the previous cooking to the start of the next cooking, so the heating dish Even when the temperature is high, there is an effect of obtaining a good baking condition.

External view of heating apparatus according to Embodiment 1 of the present invention Detailed block diagram of the equipment

  1st invention is the heating chamber which heats a to-be-heated object, the heating pan which can be attached or detached to the said heating chamber, the heating means which heats the to-be-heated object mounted on the said heating pan, A temperature detecting means for detecting the temperature, a control means for determining the heating time and controlling the heating means, and a time measuring means for measuring the time. If it is detected as high, determine the heating time for high-temperature heating, measure the elapsed time from the end of the cooking menu that uses the heating dish even if the temperature in the heating chamber at the start of heating is low, and repeat When the same cooking menu is used, the heating time is determined according to the elapsed time.

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

(Embodiment 1)
FIG. 1 is an external view of the heating device of the present invention, and FIG. 2 is a detailed block diagram of the heating device of the present invention.

  In this figure, this heating apparatus has a heating chamber 11, and a heated object 15 such as a pan is placed on a detachable heating dish 14 in the heating chamber 11, and the heated object 15 is heated by the heating means 12. The heating means includes a high frequency and a heater, and both may be provided. In the heating chamber 11, temperature detection means 13 such as a thermistor is provided to detect the temperature in the heating chamber 11.

  In the cooking menu of the heating device of the present invention, a user can set heating conditions such as temperature and time (manual menu), or a cooking condition prepared in advance and need not be set (automatic menu) There is. When bread is baked in an automatic menu, the temperature in the heating chamber 11 is detected by the temperature detection means 13 at the start of cooking on the menu, and the control means 21 determines the temperature according to the temperature and uses the heating means 12 to heat To do. The heating time is determined by a calculation formula, for example, (heating time) = (coefficient 1) − (coefficient 2) × (temperature at start). Thereby, overheating when the temperature in the heating chamber 11 is high can be prevented.

  The time measuring means 22 measures the elapsed time from the end of cooking until the next cooking start time. When baking with the same menu continuously, the heating time for the second and subsequent times is determined by changing the coefficient 1 or the coefficient 2 in the above calculation formula in accordance with the measured elapsed time. Coefficient 1 and coefficient 2 are obtained experimentally.

Even if the second and subsequent cooking menus are different from the first cooking menu, if the same heating dish 14 is used, the coefficient 1 or the coefficient 2 of the above formula is set according to the elapsed time measured by the time measuring means 22. Alternatively, the second and subsequent heating times may be determined. In addition to baking bread, put a sheet of paper on the heating pan 14 and put the food to be heated such as fried food 15 on it, or put the food in a heat-resistant container like a gratin, The menu etc. where the container is placed on the heating pan 14 and baked apply. When the menu is made, the time measuring means 22 measures the elapsed time from the end of cooking to the next cooking start time, and if the next cooking is also the menu, the coefficient 1 or the coefficient of the calculation formula according to the elapsed time. Change 2

  Thereby, overheating when the temperature of the heating pan 14 is high in continuous cooking can be prevented.

  As described above, the heating device according to the present invention can obtain a good baking condition even when the temperature of the heating pan is high.
