(Embodiment 1)
FIG. 1: shows front sectional drawing of the heating cooker in the 1st Embodiment of this invention. The cooking device 1 includes a heating chamber 2 for storing food, a food shelf 4 held by the support portions 3a and 3b of the heating chamber 2, a heater 5a for radiant heating of the food, and a microwave for heating the food by radio waves. It comprises a rotating antenna 6 having a sharp directivity to be emitted.

  The food shelf 4 has a microwave absorber 7 at the lower part of the main surface. The rotating antenna 6 rotates about the rotation axis 8 as a central axis and emits microwaves into the heating chamber 2 from the microwave discharge port 9. Food such as bread 10 is placed on the food shelf 4.

  FIG. 2 shows a side cross-sectional view of the heating cooker 1 according to the first embodiment of the present invention. As shown in FIG. 2, two heaters 5a and 5b for radiantly heating food were provided in parallel. The door 11 of the heating chamber 2 has a transparent glass window portion 12 for viewing the inside, and can be opened and closed by a handle 13. Foods such as eggs 14 were placed on the food shelf 4 and lined up with the bread 10.

  A gap 16 is provided between the food shelf 4 and the back wall surface 18 of the heating chamber 2, and a gap 17 is provided between the food shelf 4 and the glass window portion 12 of the door 11.

  About the cooking-by-heating machine 1 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. First, foods are arranged on the food shelf 4 as shown in FIGS. That is, in this case, two toast breads 10 are arranged on the door side of the heating chamber 2, and two eggs 14 for fried eggs are arranged on the back side of the heating chamber 2.

  In the menu setting display section (not shown), for example, a morning set (toast and fried egg) is selected, a quantity setting display section (not shown) is set for two persons, and cooking is started. Microwaves are emitted from the rotating antenna 6 into the heating chamber 2, the energy is supplied to the microwave absorber 7 of the food shelf 4, the food shelf 4 is heated, and the bread 10 and eggs 14 are cooked from below. At the same time, the bread 10 and the eggs 14 are cooked from above using the heaters 5a and 5b.

The weight of one of the 8-cut bread is about 49 g, the net weight of one egg is about 50 g, and the weights of both are almost the same. However, the moisture contained in the food is 38% for bread and 76% for eggs, and the moisture content of eggs is about twice that of bread even though the weight is the same. Thus, cooking eggs requires more power than bread. In this case, using the directivity of the rotating antenna 6, the microwave power distribution ratio is such that the microwaves are concentrated on the microwave absorber 7 that comes into contact with the food (egg 14) that requires more power. To control.

  In addition, when the rotating antenna 6 is controlled so as to emit microwaves toward the gap 16 where the egg 14 is placed by using the directivity of the rotating antenna 6, the microwaves are surrounded by the food shelf 4. More than the gap 17, the gap 14 can go into the upper space, and the egg 14 can be directly heated by radio waves.

  In addition, if a hole is made in the yolk membrane with a toothpick or the like, it will not rupture during heating. In addition, the heater 5a and the heater 5b installed in parallel so that a large amount of power enters the heater 5b installed in the back of the heating chamber closer to the food (egg 14) that requires more power. To control.

  In this way, a plurality of foods having different conditions, bread and eggs can be cooked so that both the upper and lower surfaces are finished optimally at the same time.

  In FIG. 3, the top view of another form of the food shelf 4 of the heating cooker in the 1st Embodiment of this invention is shown. A microwave absorber 7 is provided over the entire lower surface of the food shelf 4. Therefore, heat is generated when the microwave is absorbed, and the food placed on the food shelf can be heated from the lower surface side of the food.

  Since the food placed on the food shelf 4 comes into contact with the food shelf 4 that generates heat, the food can be burnt on the lower surface depending on the temperature of the food shelf 4.

  The rectangular microwave transmission holes 19 a, 19 b, 19 c and the microwave transmission holes 20 a, 20 b, 20 c are macro wave transmission holes provided on the door side and the back side of the heating cooker of the food shelf 4. When the microwave from the rotating antenna 6 having high directivity is emitted toward the transmission hole, the microwave passes through the transmission hole and passes through the upper part of the food shelf 4. It is possible to directly cook the food that has been guided to and placed on the food shelf 4 by radio wave heating.

  Further, when the microwave is emitted in the left-right direction of the heating chamber other than the transmission hole, there is no gap between the food shelf 4 and the support portions 3a and 3b, so that the microwave is guided to the lower space of the food shelf 4. As a result, it is absorbed by the microwave absorber 7 on the lower surface of the food shelf 4, heats the microwave absorber 7, and heats the food shelf 4.

  Thus, by providing microwave transmission holes 19a, 19b, 19c, 20a, 20b, and 20c in the food shelf 4, the microwave from the rotating antenna 6 is transmitted through the microwave transmission holes, and the food shelf 4 can be transmitted more efficiently from the lower part to the upper part, or from the upper part to the lower part. Therefore, the rotating antenna 6 for supplying microwaves is only required to be at least one of the top part and the lower part of the heating chamber. Since microwave energy can be supplied to the upper space or the lower space of 4, the food can be cooked by microwaves regardless of the food shelf 4.

  Further, even if the rotating antenna 6 that supplies microwaves is on the side surface of the heating chamber 2, the same effects as described above can be obtained as long as the microwaves can be supplied into the heating chamber 2.

  In addition, the broken-line circle 21 and the broken-line square 22 indicate positions where eggs and bread are placed. In this way, by clearly indicating the position where the food is placed, there is no misplacement of the food, the position of the food can be accurately recognized, and heating and cooking of multiple types of food using the directivity of the rotating antenna Can be implemented at the same time.

Further, the temperature sensor 25 can swing left and right, and can detect the surface temperature of the food in conjunction with the swing. For this reason, the food area can be recognized as being large, small, generally circular, or generally square, and can be cooked while detecting the surface temperature of the food. Can be finished.

  The bread cut has a square shape and a size of about 11 × 13.5 cm, so the area is about 149 square cm, and the fried egg is a round shape with a diameter of about 10 cm, so the area is about 79 square cm. Fried egg is about 0.53 times the area of bread. Thus, there is a clear difference between the two in terms of shape and area.

  In this case, as shown in the plan view of the food shelf of the heating cooker according to the second embodiment of the present invention in FIG. 5, the broken circle 21 indicating the food placement position of the food shelf 4 and the dashed square In 22, the number 1 and the number 2 are clearly shown. That is, food is placed on the number 1 for one person, and food is placed on the number 1 and number 2 portions for two.

  By doing in this way, even if it is for one person or for two persons, the temperature sensor 25 can always detect it. Therefore, in this case, the quantity setting display part is not necessary, and the result that the usability is improved can be obtained.

  Furthermore, if the temperature sensor 25 can be swung back and forth, and left and right, and configured to be able to detect the surface temperature of the entire region of the food shelf 4 in conjunction with the swing, a broken circle indicating the food placement position of the food shelf 4 It is possible to detect which part of the number 1 and number 2 specified in the square 21 and the broken-line square 22 is put on the food, so that the quantity can be distinguished more accurately, and the optimum heating It can be finished to the state.

  About the cooking-by-heating machine 1 comprised in this way, the operation | movement and an effect | action are demonstrated below. First, foods are arranged as shown in FIG. That is, in this case, two toast breads 10 are arranged on the door side of the heating chamber 2, and two eggs 14 for fried eggs are arranged on the back side of the heating chamber 2.

  Furthermore, two cups 23 and 24 containing drinks such as milk are set in the lower space of the food shelf 4. In the menu setting display section (not shown), select, for example, a morning triple (toast, fried egg & milk), set the amount setting display section (not shown) for two persons, and start cooking. . The microwave absorber 7 of the food shelf 4 can also be warmed while the microwaves are emitted from the rotating antenna 6 and the cups 23 and 24 placed in the lower space of the food shelf 4 are warmed.

The heaters 5a and 5b heat food (bread and eggs) on the food shelf 4. As in the first embodiment, the rotating antenna 6 is controlled so that the microwaves are directed toward the gap 16 close to the egg 14, and two of the two heaters installed in parallel are located behind the heating chamber. Control is performed so that more power is applied to the heater 5b closer to the installed egg. In this way, the bread 10 and the eggs 14 are cooked from the upper and lower surfaces, and the cups 23 and 24 are also heated at the same time, so that the three kinds of foods are cooked, respectively. Can be finished.

(Embodiment 4)
FIG. 7: shows front sectional drawing of the heating cooker in the 4th Embodiment of this invention.

  A temperature sensor 25 for detecting the surface temperature of the food is provided on the upper side surface of the heating chamber 2. The angle θ indicates the viewing angle of the temperature sensor 25 and is set so that approximately half of the food shelf 4 can be recognized. Further, the temperature sensor 25 is configured to be able to swing left and right, and to detect the surface temperature of the food in conjunction with the swing. For this reason, it can be recognized as a food shape, generally circular, or generally rectangular, and can be cooked while detecting the surface temperature of the food, so that the food can be finished in an optimal heating state. .

  Also in this case, as shown in FIG. 5, a broken-line circle and a broken-line square indicating the position where the food is placed on the food shelf 4, or a number 11 and a number 2 indicating the order of placement. Was specified.

  For this reason, even if it is for one person or two, it can be detected by the temperature sensor without fail. Therefore, since the food can be cooked while detecting the surface temperature of the food, the amount setting display unit is not required, and the usability is improved.

  In addition, in the case where the starting temperature differs between the food in front and the food in the back placed on the food shelf 4, for example, in the case of a combination of refrigerated sausage in the front and a side dish of bento such as frozen to fry in the back, the temperature Control is performed so that more power is input to the heater 5b on the side near the lower temperature of the food detected by the sensor 25. In this way, even if the starting temperature of the food is different, it can be finished so as to be in an optimum heating state at the same time.

  However, since the temperature of the food placed in the lower space of the food shelf 4 cannot be detected, the rotation antenna 6 that emits microwaves is controlled at a lower distribution space of the food shelf 4 at a predetermined distribution ratio. It is set to heat cook the food placed on.

  Note that there may be excess or deficiency in the cooking of food placed in the lower space of the food shelf 4. In this case, the heating adjustment display unit configured to set the distribution degree of the microwave supply is adjusted to set the microwave supply distribution degree.

  In other words, when food cooking tends to be insufficient, the setting of the heating adjustment display section is set to “add”, so that the microwave supply is supplied more to the food placed in the lower space of the food shelf. Then, the rotating antenna 6 is controlled so as to suppress the supply of the food shelf 4 to the microwave absorber 7 and the supply to the upper space of the food shelf 4.

  In addition, when the cooking of the food tends to be excessive, the setting of the heating adjustment display section is set to “weak”, so that the supply of microwaves depends on the food placed in the lower space of the food shelf 4. The rotating antenna 6 is controlled so that the supply to the microwave absorber 7 of the food shelf 4 and the supply to the upper space of the food shelf 4 are increased. Thus, by adjusting the heating adjustment display unit, the three kinds of foods can be cooked together optimally and finished.

When “addition” is set, control may be performed so that the output and time of the microwave are reduced and the output and time of the heater are increased.

  Further, when “weak” is set, the microwave output and time may be increased, and the heater output and time may be decreased.
