In FIG. 5, the steam flow path control plate 38 guides the steam flowing in from the steam inlet 34 to the vicinity of the center of the steam diffusion chamber 37, and three steam flows that are substantially vertically symmetrical about the longitudinal direction of the steam inlet. A path control plate 38a and a steam channel control plate 38b that narrows the steam channel near the center are configured. A notch 46 is provided between the respective steam flow path control plates 38a so that the steam can easily flow in the direction perpendicular to the steam flow path.

  About the cooking-by-heating machine provided with the heating container comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The user of the heating cooker 1 fits and sets the food placing tray 36 on which the food 35 is placed on the outer container 32. Further, after the lid 31 is fitted and set on the food tray 36, the steam outlet 21 of the heating chamber 2 and the steam inlet 34 of the heating container 30 are fitted and connected.

  When a cooking menu is selected from the operation display unit 28 and started, microwaves are output from the magnetrons 6a and 6b. The output microwaves are transmitted through the waveguides 14a and 14b and supplied to the rotating antennas 11a and 11b rotated by the motors 18a and 18b. 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 microwaves pass through the heating container 30 and are directly absorbed by the food 35 to generate heat.

  In particular, microwaves radiated from the lower direction tend to hit the lower surface of the food 35 and microwaves radiated from the upper direction hit the upper surface of the food and tend to be heated easily. 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, and is appropriate according to the type, shape, position, and number of the food 35. Distribution performance can be selected.

  Simultaneously with the microwave irradiation, the first steam generating heater 24 and the second steam generating heater 25 are energized to generate heat, thereby heating 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 branches at the food placing tray hole 42 and the notch 46, while the steam flow path control plate 38 a. To the center of the vapor diffusion chamber 37.

  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 scattered steam flows into the food placement chamber 45 through the food placement tray hole 42 of the food placement tray 36, condenses on the entire periphery of the food 35, gives latent heat of evaporation, and heats evenly.

  In particular, when the food 35 has a large gap (for example, noodles) or is porous, steam enters the food 35 and is efficiently heated from the inside. Moreover, when the steam is filled in the food placement chamber 45, the dielectric constant of the space changes, the microwave wavelength in the food placement chamber 45 is shortened, and there is an effect that uneven heating is reduced.

  Then, as the heating progresses and the temperature of the food 35 rises, it becomes difficult for the steam to condense on the food 35, and the food placement chamber 45 is filled with the steam. Eventually, the vapor filled without condensation is discharged from the vapor escape hole 44 to the outside of the heating container 30.

After the heating is finished, the user of the cooking device picks up the food placing plate knob 39, lifts the food placing plate 36 with the lid 31 attached, and touches the food 35 directly without touching the food 35. 2 Can be taken out. Note that the food container 35 together with the heating container 30 can be taken out of the heating chamber 2 by grasping the outer container knob 41. Of course, the lid 31 can be removed by picking the lid knob 33 and the food 35 can be directly taken out.

  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, microwave heating and steam heating can be performed with the heating container 30 removed, and the steam ejection port 21 does not protrude greatly into the heating chamber 2, so that the steam ejection port 21 does not get in the way, and the food 35 The object to be heated such as can be taken in and out.

  As described above, in the present embodiment, the steam generator 20 that generates steam, the steam outlet 21 that ejects the steam generated from the steam generator 20, and the steam ejected from the steam outlet 21 are the steam inlet 34. Through the heating container 30, the steam diffusion chamber 37 for diffusing the steam guided from the steam inlet 34 into the heating container 30 into the heating container 30, and at least a part of the steam diffusion chamber 37 communicate with each other. And a food placing tray 36 on which the food is placed.

  Thus, the steam jet 21 and the steam inlet 34 are detachably fitted to each other, thereby preventing steam leakage from the gap between the steam outlet 21 and the steam inlet 34 to the heating chamber 2 while preventing the steam flow rate. In order to increase the steam, the steam generated by increasing the internal pressure in the steam generator 30 by increasing the power of the first steam generator 24 or the second steam generator 25 or reducing the inner diameter of the steam outlet 21. Steam leakage from the connecting portion of the generator 20 and scale clogging of the inner diameter of the steam outlet 21 can also be prevented. 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.

  Further, the outer shape part of the steam outlet 21 and the inner shape part of the steam inlet 34 are overlapped and fitted, so that steam leaks from the gap between the steam outlet 21 and the steam inlet 34 into the heating chamber. Can be surely prevented. In addition, the user of the heating cooker 1 can easily align the heating container 30 simply by inserting the steam inlet 34 into the steam outlet 21.

  Further, since the food placing tray 36 is detachable from the heating container 30, after the heating is finished, the user removes the food placing tray 36 on which the food 35 is placed from the heating container 30. Therefore, the food 35 can be taken out cleanly without being burned.

  Moreover, the heating container 30 is formed of a polypropylene resin that transmits microwaves, and the food 35 can be heated not only with steam but also with microwaves, and cooking can be completed in a shorter time.

  Furthermore, by providing a steam flow path control plate 38 that changes the steam flow path in the steam diffusion chamber 37, steam is distributed evenly in the steam diffusion chamber 37, or the food 35 on the food placing plate 36. Heating unevenness 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 the food 35 on the food placing plate 36. It is possible to prevent only a part of the food from being heated, and to reduce heating unevenness of the food 35 on the food placing tray 36.

Furthermore, by providing the food placing tray convex portion 43 that floats the food 35, it becomes easier for steam from the food placing tray hole 42 directly below the food 35 to pass through, and heating unevenness of the food 35 on the food placing tray 36 is prevented. It is possible to reduce the amount of the food 35 from being caught on the food placing plate 36, and to prevent the food 35 from being forcibly taken and torn off. In addition, the heating container 30 generates heat by absorbing microwaves. By providing the heating element, the food 35 can be heated not only by steam and microwaves but also by heat conduction from the heating element.

  Moreover, if a plurality of foods are arranged in the heating container 30 and are heated simultaneously, a plurality of foods can be heated in a shorter time.

  In the present embodiment, the description has been given using the heating cooker 1 including the magnetrons 6a and 6b that generate microwaves. However, the cooking using only the steam generator 20 and the heating container 30 that do not generate microwaves is provided. Even in the case, the effect of preventing steam leakage is the same.

  Further, if the food placing plate 36 and the lid 31 are made up of members that are used up, the food placing plate 36 can be used as it is as a used tray, and the food 35 is kept in the food placing plate 36 without taking out the food 35. Can be provided to consumers.

  The food placing plate 36 on which the food 35 is placed is fitted and set on the outer container 32, and the lid 31 is fitted and set on the food placing plate 36 by the user. Thereafter, the steam outlet 21 of the heating chamber 2 and the steam inlet 34 of the heating container 30 are fitted together.

  When a cooking menu is selected from the operation display unit 28, microwaves are emitted from the magnetrons 6a and 6b. The emitted microwaves pass through the waveguides 14a and 14b and are supplied to the rotating antennas 11a and 11b rotated by the motors 18a and 18b. The microwave is irradiated to the food 35 from above and below while being stirred in the heating chamber 2 through the rotating antennas 11a and 11b. Most microwaves pass through the heating container 30 and are directly absorbed by the food 35 to generate heat.

  In particular, microwaves radiated from the lower direction tend to hit the lower surface of the food 35 and microwaves radiated from the upper direction hit the upper surface of the food 35, and the waves tend to be easily heated. 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, and is appropriate according to the type, shape, position, and number of the food 35. Distribution performance can be selected.

  At the same time as the microwaves are emitted from the magnetrons 6a and 6b, the first steam generating heater 24 and the second steam generating heater 25 are energized to generate heat, and the water storage chamber 19 is heated. Thereafter, the water storage chamber thermistor 26 detects that the temperature of the water storage chamber 19 has exceeded a predetermined temperature, and supplies the water in the water supply tank 50 to the water storage chamber 19 through the water supply path 52 by the water supply pump 51 and instantaneously steams. Is generated. 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 in two directions by the steam flow path control plate 38a. It branches at a notch 46 on the way, proceeds along the outer periphery of the vapor diffusion chamber 37 while flowing the vapor also in the central portion, and diffuses near the central portion from the end of the vapor flow path control plate 38b.

  In this way, the vapor diffuses in the vapor diffusion chamber 37 and reaches the vapor diffusion chamber 37 uniformly. The steam that has spread flows into the food placement chamber 45 through the food placement tray hole 42 of the food placement tray 36, condenses on the entire periphery of the food 35, gives latent heat of evaporation, and heats the food 35 evenly from the surroundings. To do.

  When the heating proceeds and the temperature of the food 35 rises, the steam is less likely to condense on the food 35 and fills the food placement chamber 45 with the steam. Eventually, the full steam without condensation is discharged from the steam escape hole 44 to the outside of the heating container 30.

  Note that in the present embodiment, the combined heating of the microwave and the steam is shown, but the microwave alone heating or the steam alone heating is also possible.

  As described above, in the present embodiment, the steam flow path control plate 38 is configured such that the steam flows along at least a part of the outer periphery of the steam diffusion chamber 37, so that only the central portion of the heating container 30 and the traveling direction of the steam. Steam is prevented from flowing and only a part of the food 35 on the food tray 36 is heated, and the food 35 on the food tray 36 can be heated from the surroundings to eliminate uneven heating. .

  As mentioned above, the heating cooker concerning this invention is applicable to uses, such as a microwave oven, an oven microwave oven, and a steamer which have a steam generator.
