(Embodiment 1)
1 is a front sectional view of a cooking device according to the first embodiment of the present invention, FIG. 2 is a plan sectional view of the cooking device of FIG. 1, and FIG. 3 is a partially enlarged view of the cooking device of FIG. is there.

  1 to 3, a main body 1 of the cooking device according to the present invention is provided with a heating chamber 4 in which a door 2 for taking in and out the object to be heated 3 is attached and in which the object to be heated 3 is accommodated. One end of the air flow generating means 5 communicates with the heating chamber 4 and generates an air flow in the heating chamber 4. The airflow generation means 5 is provided with a switching means (not shown) for circulating the airflow in the heating chamber 4 or taking in outside air. The heating means 6 is used when heating the air or steam in the heating chamber 4 or the object to be heated 3. The heating chamber 4 is also provided with humidity detecting means 7 for detecting the humidity of the heating chamber 4 and temperature detecting means 8 for detecting the temperature of the heating chamber 4 or the temperature of the article 3 to be heated.

  The steam from the steam generating means 9 is blown out to the heating chamber 4 via the steam outlet 10 through the steam flow pipe. In the steam flow pipe between the steam outlet 10 and the steam generation means 9, there is disposed a finer means 11 for generating a discharge in the steam flow pipe, and the steam particles generated from the steam generation means 9 are collected. It refines | miniaturizes using discharge (preferably direct-current arc discharge) etc. An injection guide 12 that specifies the injection direction of the steam is attached to the steam outlet 10 on the heating chamber 4 side.

  Further, the steam generating means 9 includes a water storage means 13 and a water heating means 14.

  The control means 15 is based on an operation input signal from an operation unit (not shown) or a signal from each detection means, an airflow generation means 5, a heating means 6, a steam generation means 9, a miniaturization means 11, and an injection guide 12. Control the operation. The heating conditions, control conditions, etc. are temporarily or permanently stored in the storage means (integrated with the control means 15). The operation unit includes a display unit, an automatic heating operation key, a manual heating setting key, a heating start key, and the like.

  About the cooking device comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when heating of the article to be heated 3 is started by an operation from the operation unit, the control unit 15 starts operations of the heating unit 6, the humidity detection unit 7, the temperature detection unit 8, the steam generation unit 9, and the injection guide 12. The control unit 15 controls the operation of the steam generation unit 9 based on detection signals from the humidity detection unit 7 and the temperature detection unit 8 that detect the humidity of the heating chamber 4. The steam generating means 9 can vary the amount of generated steam.

  Based on the detection signal of the temperature detection means 8, the control means 15 detects that there is an object to be heated in a temperature area different from the ambient temperature or an area where a temperature increase is recognized after heating for a certain period of time. When the position of the object to be heated is detected, the control means 15 controls the spray guide 12 so that steam is blown in the direction of the object to be heated. The opening area of the injection guide 12 is configured to be smaller than the opening area of the steam outlet 10, and the steam can be concentrated on the article 3 to be heated. Thus, the wetting effect of the article to be heated 3 can be increased. The steam generated in the steam generating means 9 is blown out from the steam outlet 10 into the heating chamber 4.

  The amount of generated steam is controlled by varying the input power of the water heating means 14. When the humidity of the heating chamber 4 is lower than the predetermined value, the amount of steam generated from the steam generating means 9 is increased to prevent drying. On the other hand, when the humidity of the heating chamber 4 reaches a predetermined value, the operation of the steam generating means 9 is stopped to prevent the article to be heated 3 from sticking. Further, the amount of the object to be heated is determined based on the signal from the temperature detecting means 8, and when the amount of the object to be heated 3 is large, the generated steam amount is increased from a predetermined amount.

  The miniaturization means 11 refines the steam generated by the steam generation means 9. Usually, when the refinement means 11 is not used, the particle size of the vapor particles is small immediately after generation, but the particles gradually aggregate to increase the particle size. On the other hand, when the miniaturization means 11 is used, water molecules aggregate in repulsive nuclei generated by the discharge of the miniaturization means 11. Since nuclei in which water molecules are aggregated repel each other, vapor particles can be prevented from further aggregating. For this reason, the refinement | miniaturization state of particle | grains can be maintained. The miniaturization means 11 can control the miniaturization corresponding to the amount of steam by changing the discharge time.

  By miniaturizing the steam, there is little condensation on the surface of the article 3 to be heated, but the steam can penetrate into the interior. In addition, the vapor particle diameter can be varied, and steam having a particle diameter according to the state of the article to be heated 3 can be introduced. In steam cooking, the refinement means is not operated, and steam having a large steam particle diameter (so-called steam) is used to increase the amount of heat from the steam to the article 3 to be heated. On the other hand, when supplying moisture while suppressing the temperature rise of the article to be heated 3 or when attaching a small amount of vapor to the entire surface of the article to be heated 3, the micronizing means is operated to reduce the particle size.

  As mentioned above, the quality of the to-be-heated to-be-heated material 3 cooked by refine | purifying a vapor | steam according to the state of the to-be-heated material 3 can be improved.
