To set, touch one of the steam icon (104), the humidifying oven icon (105), and the oven icon (106) displayed on the home screen (see FIG. 10) displayed on the touch panel (8). To do. The control means (9) controls the operation of the heating means (3) and the steam generation means (4) by the cooking program based on the operating condition input by the input means (6), and performs cooking, steam and heating. The cooking ingredients are cooked by selecting any one of the combination cooking and steam cooking.

  When cooking ingredients, the setting screen displays the temperature, time, and steam amount set values input by the input means (6), and the actual temperature and time at the same time. In the setting screen displayed in FIG. 10, the actual temperature is displayed on the right side and the set temperature is displayed on the left side. Thereby, the user can grasp | ascertain exactly the cooking condition and cooking condition of a foodstuff. The actual temperature is measured by the temperature detection means (27). The actual time is measured by a timer (28).

  A shelf (20) is installed in the cooking cabinet (2) as shown in FIG. The shelf (20) has a plurality of shelves so that a plurality of hotel pans can be installed in the cooking chamber (2). The input means (6) selects and cooks one of the cooking methods of cooking, steam and heating combined use, steam cooking for each shelf level via a setting screen (shelf screen described later) You can set the time. Thereby, the some foodstuff from which cooking time differs can be cooked simultaneously, and the efficiency of cooking work improves.

The calculation means (10) is realized by the control means (9) executing a predetermined calculation program stored in the storage means (26), and the door (14) is opened and closed during cooking. In addition, the amount of heat energy lost in the cooking cabinet (2) is calculated based on a predetermined calculation formula. The control means (9) corrects the cooking time (the execution time of any of the above three cooking methods) based on the calculation result by the calculation means (10).
When cooking ingredients with different heating times at the same time, when the door of the cooking cabinet (2) is opened in order to take out the ingredients with a short heating time, the temperature inside the cooking cabinet (2) decreases, and another cooking process is in progress. The food is not sufficiently heated according to the set temperature and is not cooked as set. The calculation means (10) grasps the temperature decrease caused by opening and closing the door (14) based on the detection value by the temperature detection means (27), and calculates the amount of heat energy lost due to the temperature decrease and the amount of heat energy. Calculate the heating time required to replenish. The control means (9) corrects (extends) the heating time to compensate for the temperature drop in the cooking chamber (2) based on the calculation result by the calculation means (10).
Thereby, even when cooking the some foodstuff from which cooking time differs, there is no difference in the quality of a foodstuff.

Furthermore, the calculation means (10) calculates the amount of energy required for heating to a predetermined temperature according to the food material. Specifically, the amount of energy required to heat the food to a predetermined temperature is calculated based on the temperature gradient when the temperature of the food being heated is raised. Alternatively, the amount of energy necessary for heating the food to a predetermined temperature can be calculated by the user inputting the mass of the food. Thereby, correction of the heating time of a foodstuff can be performed.
That is, the control means (9) loses heat energy in the cooking chamber (2) due to the opening / closing operation of the door (14) of the cooking chamber (2) during cooking by the calculation means (10). The cooking time (the execution time of any of the above three cooking methods) is corrected based on the amount and the calculation result of the amount of energy required for heating to a predetermined temperature according to the food.
Specifically, when the mass of the introduced food is large, the temperature gradient for raising the temperature of the food is small, and the time for the temperature in the cooking chamber (2), which has been lowered by opening and closing the door, to return to the set temperature is long. When the mass of the food is small, the temperature gradient for raising the temperature of the food is large, and the time for returning to the set temperature is short. Therefore, the control means (9) corrects the cooking time in the former case to be longer than in the latter case. By making it possible to correct the cooking time for the length of the return time, cooking can be performed without any difference in the quality of the food regardless of the mass of the food.

  The spraying means (12) is composed of a spray nozzle. When cooling the inside of the warehouse, the spraying means (12) sprays water into the warehouse, and when used as the steam generating means (4) for generating steam, the heating means (3) is used. Spray with water. An injection means (5) consists of a sprinkler arrange | positioned at the upper wall surface in a cooking chamber, and injects pressure water from the nozzle which rotates when the inside is cooled and cleaned (refer FIG. 8).

  The steam convection oven (1) according to the present invention includes a cooling means (11) for cooling the inside of the cooking chamber (2). The cooling means (11) is controlled based on the cooling program stored in the storage means (26) by the control means (9). Specifically, the operation of the spraying means (5) and the spraying means (12) is controlled based on the condition input by the input means (6) via the setting screen, and the cooking chamber (12) is controlled by the spraying means (12). 2) After spraying mist-like water, water is injected into the cooking chamber (2) by the injection means (5). Thus, after cooling with mist-like water first, the inside of the cooking chamber (2) which becomes high temperature is not rapidly cooled by cooling with the jet water, and the inside of the cooking chamber (2) It is possible to prevent the metal from being deformed.

The operation of the cooling means (11) will be described more specifically. First, when the temperature in the cooking chamber (2) detected by the temperature detection means (27) is equal to or higher than the first predetermined temperature (for example, 200 ° C.), the spray means (12) forms a mist in the cooking chamber (2). Of water intermittently. When the temperature in the cooking chamber (2) decreases and becomes equal to or higher than the second predetermined temperature (for example, 150 ° C.) and lower than the first predetermined temperature, the spray means (12) causes mist water to enter the cooking chamber (2). Spray continuously. When the temperature in the cooking chamber (2) further decreases and becomes lower than the second predetermined temperature, water is intermittently injected into the cooking chamber (2) by the injection means (5) for a predetermined time and then continuously injected.
In this way, depending on the internal temperature, the injection means (5) and the spray means (12) are selectively used to gradually cool the internal temperature, so that the inner wall surface of the cooking chamber is not deformed, and the The interior can be quickly cooled. The first predetermined temperature, the second predetermined temperature, the intermittent spraying, and the intermittent injection conditions can use preset values stored in the program, but they can also be input on the setting screen according to the internal situation. it can. Furthermore, when performing cooling by spraying, the timing for switching from intermittent to continuous is the time and number of times of intermittent spraying in addition to the aforementioned internal temperature (continuous after repeating intermittent spraying for 1 minute or 10 times. It can be switched according to spraying.

  The storage means (26) stores operating conditions set by the user in addition to the cooking program, cooking menu, cooling program, and cleaning program.

  An example of the function provided in the steam convection oven (1) of the present invention will be described.
