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

(Embodiment)
1 to 3 show a cooking device according to an embodiment of the present invention.

  As shown in FIGS. 1 and 2, the cooking device according to the present embodiment has a heating chamber in which a door 2 for taking in and out the object to be heated 3 is attached to the main body 1 and the object to be heated 3 is accommodated. 4 is incorporated. The heating chamber 4 is provided with an airflow generating means 5 and a placing means 6 for placing the article 3 to be heated. The air flow generating means 5 is composed of a fan, and one end communicates with the heating chamber 4 to generate an air flow in the heating chamber 4. The airflow generated by the airflow generation means 5 is provided with a switching means (not shown) that circulates in the heating chamber 4 or takes in outside air. The mounting means 6 is a rotary table that is rotated by the rotating means 16 during heating in order to prevent uneven heating.

  The heating means 7 disposed outside the heating chamber 4 is used when the object to be heated 3 or the heating chamber 4 is radiantly heated. The microwave generation means 8 supplies microwaves to the heating chamber 4 when the object to be heated 3 is heated by microwaves. The heating chamber 4 is also provided with temperature detecting means 9 for detecting the temperature of the article to be heated 3 or the heating chamber 4.

  The steam generating means 10 that generates steam to be supplied into the heating chamber 4 blows out the generated steam from the steam outlet 12 to the heating chamber 4 through the steam flow pipe 11a and the steam flow pipe 11b. The steam generation means 10 includes a water storage means 13 and a water heating means 14. Between the steam flow pipe 11 a and the steam flow pipe 11 b between the steam outlet 12 and the steam generation means 10, a miniaturization means 15 for generating a discharge is disposed, and generated from the steam generation means 10. Vapor particles are refined using discharge (preferably direct current arc discharge) or the like.

  As shown in FIG. 3, the steam outlet 12 is provided with an injection guide 18 for specifying the steam injection direction on the heating chamber 4 side, and the direction is as shown in FIGS. 3 (a) and 3 (b). Or can be freely changed in the left-right direction.

  The control means 17 shown in FIG. 1 is based on the operation input signal from the operation part (not shown) of the main body 1 or the detection signal of the temperature detection means 9, the air flow generation means 5, the heating means 7, and the microwave generation. Operations of the means 8, the steam generation means 10, the miniaturization means 15, the injection guide 18, the rotation means 16, and the like are controlled. The heating conditions, control conditions, etc. are temporarily or permanently stored in the storage means (integrated with the control means 17). The operation unit includes a display unit, an automatic heating operation key, a manual heating setting key, a heating start key, and the like.

  Next, the operation | movement and effect | action are demonstrated about the heat cooking apparatus which consists of the said structure.

  When heating of the article to be heated 3 is started by an operation from the operation unit, the control unit 17 operates the heating unit 7, the microwave generation unit 8, the temperature detection unit 9, the steam generation unit 10, the rotation unit 16, and the injection guide 18. Start.

  The steam generation means 10 can vary the amount of generated steam. The amount of generated steam is controlled by varying the input power of the water heating means 14. The steam generated in the steam generating means 10 is blown out from the steam outlet 12 into the heating chamber 4. The control means 17 normally controls the injection guide 18 so that the steam is uniformly introduced into the heating chamber 4, but when increasing the humidification of the object to be heated 3, the steam is directed in the direction of the object to be heated 3. The injection guide 18 is adjusted so as to be blown out (FIGS. 3A and 3B).

  The miniaturization means 15 refines the steam generated by the steam generation means 10. Usually, when the refinement means 15 is not used, the particle size is small immediately after the generation of the vapor, but the vapor particles gradually aggregate to increase the particle size. On the other hand, when the miniaturization means 15 is used, water molecules aggregate in repulsive nuclei generated by the discharge of the miniaturization means 15. 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 15 can control the miniaturization corresponding to the amount of steam by changing the discharge time. By refining the steam, steam having a particle diameter corresponding to the type and state of the article to be heated 3 can be introduced.

  The mounting means 6 is prepared by using different materials, and the user can select materials according to the heating means 7 and the microwave generating means 8 to be used. For example, when the microwave generating means 8 is mainly used, a material that hardly absorbs microwaves is selected for the placing means 6 in order to efficiently supply microwave heat to the article 3 to be heated. On the other hand, when the heating means 7 is used as a main heat source for cooking, a material having any one of characteristics such as heat resistance, heat storage, and heat insulation is selected. From this, the to-be-heated material 3 can be heated efficiently.

  Next, operations during cooking will be described based on individual examples.

  For example, food (rice cooked rice) that is easily dehydrated when the article to be heated 3 is heated only by microwaves is heated while being humidified by increasing the amount of steam. On the other hand, on the other hand, the skin of meat buns, etc., need to be moderately humidified. Therefore, the appearance of the article to be heated 3 can be improved by operating the micronization means 15 to micronize the vapor particles and heating while preventing the skin from swelling. In steam cooking that requires further humidification, the operation of the miniaturization means 15 is stopped, and steam with a large particle diameter (so-called steam) is used to enhance the humidification effect.

  First, an example in which the vapor particle size is varied according to the operation of the heating means 7 and the microwave generation means 8 will be described. For example, vapor has the property of absorbing microwaves when the particle size exceeds a certain size. Therefore, in microwave heating, when the temperature rise is accelerated before the article to be heated 3 is dried, the micronization means 15 is operated so that the vapor does not aggregate to a particle size that absorbs the microwave. On the other hand, in the case of hot air heating or the like, the input steam absorbs the heat in the heating chamber 4 and the particle size of the steam immediately decreases, so the miniaturization means 15 may be stopped.

  Next, an example of operating the steam generation means 10 and the miniaturization means 15 until the condensed water on the surface of the object to be heated reaches a certain amount or more before the microwave heating will be described. For example, when the object to be heated 3 is a vegetable, it is dried when it is overheated by microwaves, so microwave heating is performed while preventing drying. Therefore, control is performed to prevent excessive drying by condensing steam on the vegetable surface before microwave heating.

  When the particle size of the steam is large, the difference in the amount of water condensed on the vegetable surface is large. In addition, due to uneven adhesion of steam to the vegetable surface, the microwaves are not evenly irradiated to the vegetable and uneven heating occurs. For example, the dewed portion has a large amount of adhering water, so it is difficult to overheat, but the portion with less adhering water is dried. In addition, when the particle size is large, it is difficult for steam to enter a small gap formed by overlapping vegetables. Therefore, the difference in the presence or absence of adhering water is further increased.

  On the other hand, when the steam is refined, the steam enters the small gap formed by the vegetables overlapping each other, and the steam adheres evenly to the vegetable surface. Therefore, heating unevenness due to microwaves can be eliminated, and the quality of the article to be heated 3 can be improved.

  The amount of condensed water adhering to the surface is calculated by the control means 17 from the comparison of the type, weight, volume, etc. of the article 3 to be heated and the steam charging time. The basic condition to be compared is stored in the storage means, and the control means 17 calculates based on the information in the storage means.

  As described above, the quality of the article to be heated 3 after cooking by heating can be improved by refining the steam and heating the article to be heated 3 while being appropriately moistened.

  As described above, in the cooking device according to the present invention, the refined steam is supplied to the object to be heated, and cooking can be performed while the object to be heated is appropriately moistened. It is also effective for cooking with a high-frequency heating cooking device combined with an oven or a griller. In particular, it is suitable for cooking of an object to be heated in a microwave oven.
