A notch 46 is provided between each steam flow path control plate 38a so that the steam can easily flow in the direction perpendicular to the steam flow path.

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

  The user of the microwave heating cooker 1 is set by fitting the first food placing plate 36a on which the first food 35a is placed on the outer container 32. Further, after the second food placing plate 36b on which the second food 35b is placed is fitted and set on the first food placing plate 36a, the lid 31 is placed on the second food placing plate 36a. It fits on the plate 36b so that the outer shape of the steam outlet 21 of the heating chamber 2 and the inner shape of the steam inlet 34 of the heating container 30 are matched.

  Then, when the cooking menu is selected from the operation display unit 28 and started, microwaves are output from the magnetrons 6a and 6b, and the output microwaves are transmitted through the waveguides 14a and 14b, and the motors 18a and 18b. Is supplied to the rotating antennas 11a and 11b that rotate. The supplied microwave is irradiated from above and below while being stirred into the heating chamber 2 via the rotating antennas 11a and 11b. Most of the microwaves are transmitted through the heating container 30 and directly absorbed by the first food 35a and the second food 35b to generate heat.

In particular, as the characteristics of the microwave, the closer to the antenna, the easier the direct wave hits and the more easily heated, the second food 35b is more easily heated than the first food 35a. In addition, since frozen foods tend not to absorb microwaves, the first food 35a, which is a frozen food, is less likely to be heated than the second food 35b, which is a refrigerated food. Moreover, the microwave distribution in the heating chamber 2 can be changed by controlling the output of the upper and lower microwaves and the rotating antennas 11a and 11b, which is appropriate for the type, shape, position, and number of food. Distribution performance can be selected.

  At the same time as the microwave is output, the first steam generation heater 24 and the second steam generation heater 25 are energized to generate heat and heat the water storage chamber 19. Thereafter, the water storage chamber thermistor 26 detects that the temperature of the water storage chamber 19 has exceeded a predetermined temperature, the water in the water supply tank 50 is supplied to the water storage chamber 19 through the water supply path 52 by the water supply pump 51, and steam is instantaneously generated. generate. Note that steam may be gradually generated by storing water in the water storage chamber 19 and heating it.

  The generated steam is ejected from the steam outlet 21 through the steam introduction path 23 from the water storage chamber 19. The steam ejected from the steam outlet 21 flows into the steam diffusion chamber 37 through the steam inlet 34 of the heating container 30 and is branched at the middle notch 46 by the steam flow path control plate 38a, while the center of the steam diffusion chamber 37. Guided to the department.

  The steam guided to the central portion of the vapor diffusion chamber 37 is narrowed by the steam flow path control plate 38b, and the flow path branches in three directions. The branched steam diffuses in the vapor diffusion chamber 37 and reaches the vapor diffusion chamber 37 uniformly. The steam that has flowed in flows into the first food placement chamber 45a through the first food placement tray hole 42a of the first food placement tray 36a, condenses on the entire periphery of the first food 35a, and evaporates. Give latent heat and heat evenly.

  Thereafter, when the first food 35a is heated, the steam that cannot be heated is transferred to the second food placement chamber 45b through the second food placement hole 42b of the second food placement tray 36b. It flows in, condenses on the entire periphery of the second food 35b, gives latent heat of evaporation, and heats evenly. In particular, when the first food 35a or the second food 35b is a thing with many gaps (for example, noodles) or a porous one, steam enters the first food 35a or the second food 35b, It is also heated efficiently from the inside.

  Further, when the steam is filled in the food placement chamber 45a or the food placement chamber 45b, the dielectric constant of the space is changed, the wavelength of the microwave in the food placement chamber 45a or the food placement chamber 45b is shortened, and uneven heating is performed. Has the effect of mitigating.

  Moreover, the heating conditions of the first food 35a can be changed by controlling the steam output. For example, when it is desired to heat the first food 35a more, the steam output is increased, and when the second food 35b is desired to be heated further, the steam output is decreased, and the main heating means is changed to the microwave. The heating balance between the food 35a and the second food 35b can be adjusted.

  When the heating proceeds and the temperature of the first food 35a and the second food 35b rises, the steam is less likely to condense on the first food 35a and the second food 35b, and the food is loaded with the steam. The storage room 45a and the food storage room 45b are filled. The steam that is finally filled without condensation is discharged from the steam escape hole 44 to the outside of the heating container 30.

  After the heating is completed, the user of the microwave heating cooker 1 pinches the first food placing plate knob 39a and keeps the second food placing plate 36b and the lid 31 attached, and then places the first food placing plate. The first food 35a and the second food 35b can be taken out of the heating chamber 2 without lifting the plate 36a and directly touching the first food 35a and the second food 35b. It is also possible to pick up the second food placing plate knob 39b, lift the second food placing plate 36b with the lid 31 attached, and take out the second food 35b to the outside of the heating chamber 2.

Moreover, the food container 35 can be taken out of the heating chamber 2 together with the heating container 30 by picking the outer container knob 41. Of course, the lid 31 can be removed by pinching the lid knob 33 and the food 35 can be taken out directly.

  Note that in this embodiment mode, the combined heating of the microwave and the steam is shown, but microwave heating alone or steam heating alone is also possible. Further, the heating container 30 can be removed to perform microwave heating and steam heating, and the steam jetting port 21 does not protrude greatly into the heating chamber 2, so that the steam jetting port 21 does not get in the way, food and the like The object to be heated can be taken in and out.

  As described above, in the present embodiment, magnetrons 6a and 6b that generate microwaves, a steam generator 20 that generates steam, a steam outlet 21 that ejects steam generated from the steam generator 20, and a steam jet A heating container 30 in which steam ejected from the outlet 21 is guided through the steam inlet 34, at least one first food 35a that is easily heated by the steam in the heating container 30, and at least one second food 35b that is not easily heated by the steam. And is placed.

  As a result, the first food 35a is heated mainly by the steam guided from the steam inlet 34. The second food 35b is heated mainly by the microwave generated from the magnetron 6b. For this reason, the first food 35a that is easily heated by steam is mainly heated by steam, and the second food 35b that is difficult to be heated by steam is mainly heated by microwaves. Thus, even when foods having different heating efficiencies by a plurality of steams are heated, overheating and insufficient heating can be prevented and simultaneous heating can be efficiently performed in a short time.

  In addition, since the second food 35b is a food that absorbs microwaves more easily than the first food 35a, the second food 35b can be heated with microwaves more quickly, and efficiently in a short time. Simultaneous heating is possible.

  Furthermore, since the second food 35b is placed in the vicinity of the rotating antennas 11a and 11b rather than the first food 35a, the microwave direct wave can be easily supplied to the second food 35b, and more. The second food 35b can be quickly heated by microwaves, and can be efficiently heated simultaneously in a short time.

  In addition, the second food 35b is heated using the surplus steam that could not heat the first food 35a, so that the surplus steam can be used for heating the second food 35b without waste, Simultaneous heating can be efficiently performed in a short time.

  Furthermore, the first food 35a and the second food 35b are at least partially communicated with each other so that steam can pass therethrough, and the second food 35b is more than the first food 35a in the direction of travel of the steam. By being placed on the downstream side, the steam that has passed through without being able to heat the first food 35a can be directly used for heating the second food 35b, and can be simultaneously and efficiently heated in a short time.

  In addition, a first food placing plate 36a for placing the first food 35a and a second food placing plate 36b for placing the second food 35b are provided, and the first food placing plate 36a is provided. And at least one of the second food placing tray 36b is detachable from the heating container 30, so that after the heating is finished, the user places the first food 35a and the second food 35b. Since the detachable first food placing plate 36a or the second food placing plate 36b can be removed from the heating container 30, there is no need to directly touch the first food 35a or the second food 35b, which causes burns. The food can be taken out cleanly.

Furthermore, a steam generator 20 that generates steam, a steam outlet 21 that ejects steam generated from the steam generator 20, a heating container 30 through which steam ejected from the steam outlet 21 is guided through a steam inlet 34, A steam diffusion chamber 37 for diffusing the steam introduced from the steam inlet 34 into the heating container 30 and the steam diffusion chamber 37 at least partly communicates with the steam, and the first food 35a is loaded. The first food placing tray 36a is placed, and the steam outlet 21 and the steam inlet 34 are detachably fitted.

  Accordingly, the first steam generating heater 24 and the second steam generating heater 25 are used in order to increase the steam flow rate while preventing steam leakage to the heating chamber 2 from the gap between the steam outlet 21 and the steam inlet 34. By increasing the electric power or reducing the inner diameter of the steam outlet 21, the internal pressure in the steam generator 30 is increased to prevent steam leakage from the joint of the steam generator 20 and the clogging of the inner diameter of the steam outlet 21. Moreover, when the user fits the steam outlet 21 and the steam inlet 34, the positioning of the heating container 30 can be easily performed.

  In addition, the outer shape portion of the steam outlet 21 and the inner shape portion of the steam inlet 34 are overlapped and fitted, so that the gap between the steam outlet 21 and the steam inlet 34 is surely connected to the heating chamber. Steam leakage can be prevented, and the user can easily align the heating container 30 simply by inserting the steam inlet 34 into the steam outlet 21.

  Furthermore, the heating container 30 is formed of a polypropylene resin that transmits microwaves, so that food can be heated not only with steam but also with microwaves, and cooking can be completed in a shorter time.

  In addition, by providing the steam flow path control plate 38 for changing the steam flow path in the steam diffusion chamber 37, the steam is distributed evenly in the steam diffusion chamber 37 or on the first food placing plate 36a. The unevenness of heating of the first food 35a can be reduced.

  Further, the steam flow path control plate 38 is configured to narrow or bend the steam flow path so as to face the steam traveling direction, so that the steam flows only in the steam traveling direction and is on the first food tray 36a. Only a part of the first food 35a can be prevented from being heated, and heating unevenness of the first food 35a on the first food placing plate 36a can be reduced.

  Furthermore, by providing the first food placing plate convex portion 43a for floating the first food 35a and the second food placing plate convex portion 43b for floating the second food 35b, the first food 35a, Vapor from the first food placing plate hole 42a and the second food placing plate hole 42b immediately below the second food 35b is easily passed, and the first food 35a on the first food placing plate 36a, And the heating unevenness of the second food 35b on the second food placing plate 36b can be reduced, and the first food 35a and the second food 35b are the first food placing plate 36a and the second food. It can also be prevented that it becomes difficult to be caught on the mounting plate 36b, or it is difficult to forcibly tear it off.

  In addition, by providing the heating container 30 with a heating element that absorbs microwaves and generates heat, the first food 35a and the second food 35b can be transferred not only by steam and microwaves but also by heat conduction from the heating element. It can also be heated.

  Although the microwave heating cooker 1 that generates microwaves is used in the present embodiment, steam leakage is prevented even in a heating cooker provided with only the steam generator 20 and the heating container 30 that do not generate microwaves. The effect is something as well.

Further, if the first food placing plate 36a, the second food placing plate 36b, and the lid 31 are composed of used members, the first food placing plate 36a and the second food placing plate 36b are used as they are. It can be used as a single-use tray, and the first food 35a and the second food 35b can be added to the first food placing plate 36a and the second food placing plate 36b without taking out the first food 35a and the second food 35b.
