Description

  The present invention relates to a microwave oven with an oven function that can uniformly heat pizza dough, and a pizza cooking method using the same.

In recent years, various processed foods have been developed, and microwave ovens with an oven function are often used to cook these foods.
For example, a pizza cooking utensil as shown in FIG. 5 has been proposed as a heating container capable of maintaining a crispy texture such as pizza dough and heating the back surface substantially uniformly. (See Patent Document 1).
JP 2001-120424 A

In the figure, reference numeral 110 denotes an integral molding made of a plastic material having resistance to microwave heating, 111 denotes a bottom portion of the container, and a plurality of frustoconical protrusions 114 are formed on the top surface of the bottom portion 111. It is arranged. Reference numeral 112 denotes a side wall that surrounds the entire circumference of the bottom surface portion 111. The heating food mounting portion 113 having a horizontal surface 113 a is intermittently provided inside the side wall 12 so that food can be stably placed along the heel portion of the bottom surface. (Six in the figure). The side wall 112 is provided with a portion whose upper end is higher and lower than the height of the horizontal surface 113 a of the mounting portion 113.
However, this was due to microwave heating, and even if it could be heated evenly, the liver and kidneys were not burnt, so the appetite was not finished.

  Therefore, the present invention uses an oven instead of microwave heating of a microwave oven with an oven function in order to give a crisp burn in pizza cooking, and in particular, heaters are provided on the upper and lower sides of the inner wall of the microwave oven. It is a pizza dish by using the type of arrangement.

In the case of a microwave oven in which heaters are arranged on the upper and lower sides of the inner wall, the upper heater employs a surface heater that spreads across the ceiling, whereas the lower heater is usually a sheathed heater, a tube heater, etc. It consists of two one-dimensional heating elements. This is because the lower central surface is provided with a radio wave agitation antenna and turntable for use as a microwave oven, so there is no space for adopting a surface heater on the lower side. Therefore, one linear sheathed heater is disposed on each side of the radio wave agitating antenna and turntable.
When trying to bake pizza using such microwave oven heating, the following inconvenience occurred.

  FIG. 4 shows a conventionally used cooking utensil, and a wire mesh as shown in the figure was used. In the figure, 40 is a heating wire mesh, 40a is a four-sided beam, 40b is a connecting beam, 40c is a leg, and 40d is a gap. In such a heating wire mesh 40, the pizza was burnt in the four-sided beam 40a and the connecting beam 40 that support the pizza, and the baking unevenness that the pizza was not completely baked in the gap portion 40d was formed.

  In addition, when cooking raw pizza by placing it on a ceramic dish, the lower heater is heated by placing this dish on the bottom of the microwave oven, but the portion directly above the sheathed heater is heated quickly. However, the pizza in the other part (the part located between the sheathed heater and the other sheathed heater) was burnt (disadvantage 1: burn unevenness on the back of the pizza).

  Furthermore, between the front side of the pizza (the ceiling side of the microwave oven) and the back side of the pizza (the surface in contact with the dish), the back side (bottom surface) of the pizza is baked crisply, and the front side of the pizza is baked. It was difficult to heat the pizza so that there was no. (Disadvantage 2: heating unique to the front and back of the pizza).

In addition, round dishes (made of porcelain) used for normal cooking have a small heat capacity, and the temperature of the dishes fluctuates greatly by opening and closing the microwave door, and it takes time for the pizza to be baked. Unevenness occurred.
Furthermore, round dishes (made of ceramics) used for ordinary cooking were difficult to remove, and were easily chipped with a slight impact, and the microwave oven table and the microwave oven shelf were easily damaged.
Moreover, in order to float the plate and bring it closer to the upper heater, a net was placed using a shelf of a microwave oven, and a plate was placed thereon to bake the pizza. However, the baking unevenness due to the lower heater was not resolved.
Thus, metal wire mesh, ceramic dishes, heat storage plates, and metal square dishes have been used in the past, so it is still necessary to uniformly heat the entire pizza surface and to heat the pizza front and back. The above-mentioned various inconveniences also existed.

  The present invention was made in order to solve the above-mentioned problems all at once. The pizza cooking is easy to remove dirt, does not damage the surroundings, is baked uniformly and quickly over the entire surface, and the baking of the front and back surfaces can be performed uniquely. The purpose is to provide equipment.

The invention according to claim 1 relates to a microwave oven with an oven function, and in the microwave oven with an oven function, in the case of preheating in a pizza cooking mode using a pizza cooking utensil, after a predetermined time has elapsed after opening the door upon completion of preheating. It features a buzzer that prompts the door to close.
According to a second aspect of the present invention, in the microwave oven with an oven function according to the first aspect, when preheating is performed in the pizza cooking mode, a buzzer is sounded after a predetermined time from the start of the preheating so as to notify the end of the preheating. It is characterized by that.
The invention according to claim 3 is the microwave oven with oven function according to claim 1 or 2, in the case of cooking and heating in the pizza cooking mode, a buzzer is sounded after a predetermined time from the start of cooking and heating is notified. It is characterized by doing so.
In the microwave oven with an oven function according to claim 2 or 3, in the pizza cooking mode, when the time from opening the door to closing exceeds a predetermined time, it corresponds to the excess time. The system is characterized in that the buzzer is sounded by delaying the time to compensate for the temperature drop to be performed or when the internal temperature detection sensor reaches a predetermined temperature.
Invention of Claim 5 arrange | positions a heater on the upper side and the lower side of an inner wall, and the pizza cooking utensil in the microwave oven of any one of Claims 1-4 of the structure which can place a cooking dish in two steps | paragraphs of upper and lower sides. In the pizza cooking method of cooking pizza using, the pizza cooking utensil is placed on the upper stage and preheated, and then the pizza cooking utensil on which the pizza is placed is placed on the lower stage and cooked and heated. It is a feature.
In the invention according to claim 6, the pizza cooking utensil is placed in a square plate with a metal rim having the same square shape as the size and shape in the microwave oven, and the square plate with a metal rim. A ceramic circular dish having a size and a diameter approximately equal to one side of the metal-edged square dish, and the back side of the ceramic circular dish has a diameter larger than ½ of the diameter of the dish. An annular cradle is formed, and an edge is provided around the circular dish.

  According to the microwave oven of the present invention, when the door is left open for a long time, the buzzer sounds, so the cook is prompted to close the door quickly, and the buzzer is turned on after a predetermined time from the start of preheating. Since the cooker will notify the end of the preheating so that the cook will know the preheating accurately, and after the cooking heating has started, the buzzer will sound and notify the end of the cooking heating. The cooking time is shortened and further contributes to energy saving.

  Further, in the pizza cooking mode, when the time from opening the door to closing exceeds a predetermined time, it is delayed by the time to compensate for the temperature drop corresponding to the excess time, or the inside temperature detection sensor is set to the predetermined temperature. Since the buzzer is sounded when the temperature reaches the value, it is possible to save time and effort for the cook to perform temperature compensation by opening the door for a long time during the cooking time of the pizza.

According to the pizza cooking method of the microwave oven according to the present invention, the crust surface is baked uniformly over the entire surface, and the crust surface becomes crispy, and the crust inside and the ingredients can be made quickly and energy-saving delicious pizza without shrinkage. Become.
At that time, in particular, when using a pizza cooking utensil comprising a combination of a square metal-edged square dish and a ceramic circular dish as shown in FIG. 1, the thermal efficiency is improved, and the entire surface is further baked uniformly. Even after baking, the surface of the crust becomes crispy, and the crust interior and ingredients can quickly and energy-saving to produce delicious pizzas without shrinkage.

BEST MODE FOR CARRYING OUT THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a pizza cooking appliance for a microwave oven with a built-in heater according to the present invention, 10 is a pizza cooker for a microwave oven with a built-in heater according to the present invention, 11 is a heat storage circular dish made of ceramics, and 12 is made of metal. It is a square dish with a rim. The metal-made square dish 12 is of a size that can be accommodated on a shelf in a microwave oven, and is a square dish having the same square shape as the interior of the oven. The reason why the metal dish is preferably a square dish having the same square shape as the inside of the box is that if it is done in this way, it spreads all over the box so that it can absorb a large amount of heat in the box and quickly becomes high in temperature (high heat).
However, when the pizza is placed directly on a metal square dish, the portion in contact with the dish becomes darkened, and the surface cannot be burned sufficiently from the inside, and unevenness is generated as described above in the conventional defect. Therefore, here, the problem of unevenness is solved by placing a circular dish on a metal square dish that quickly becomes hot (high heat). Therefore, it is desirable that the ceramic circular dish 11 has a size that can be placed on the square dish 12 with a metal edge. That is, the diameter of the circular dish 11 is substantially equal to one side of the square dish 12.

2A and 2B are diagrams for explaining a ceramic circular dish 11 according to the present invention, in which FIG. 2A is a front perspective view, FIG. 2B is a transverse sectional view, and FIG. 2C is a rear perspective view.
In the figure, reference numeral 11a denotes a flat surface on the front side of the plate, on which pizza is placed. 11b is a flat surface on the back side of the dish, and 11c is an edge. 11d is a back side taper part, and since this is formed, it becomes easier for a hand to enter under a plate compared with a flat plate, and it becomes easy to lift. 11e is an annular cradle. Further, the ceramic circular dish 11 is coated with glaze.

  The annular cradle 11e has a circular shape, and the diameter of the circular shape is larger than ½ of the diameter of the dish. By doing in this way, since the metal-edged square dish 12 receives the weight of the circular dish 11 in a wide surface, the metal plate of the metal-edged square dish 12 having a small thickness can be used. On the other hand, when the circular diameter of the annular pedestal 11 is small, the metal-edged square dish 12 receives the weight of the circular dish 11 on a narrow surface, and the square dish 12 is easily thermally deformed by heating. . In order to prevent the thermal deformation, it is necessary to increase the thickness of the metal plate of the metal-edged square dish 12.

In addition, when a heat storage square dish was used instead of the circular dish according to the present invention, the temperature did not rise sufficiently within the same heating time, and a firm burnt color was not obtained. The reason for this is that when a round pizza of the same size as that heated in a round dish is heated using a square dish, the square dish has a larger area than the round dish, so the same amount of heat is given per unit area. It is surmised that the temperature rise will be low.
In addition, the used pizza is circular (pizza is generally circular), and there is a disadvantage that the corner portion where the pizza is not placed is heated wastefully.

Therefore, baking was quickened by using the circular dish according to the present invention.
Moreover, there is a merit that it can be put out as a plate on the table as it is.
Furthermore, in the case of a circular dish, when removing the dish from the metal square dish, there is a gap between the corner of the square dish and the round dish, so the hand enters the gap so that the dish is removed from the square dish. There is a further advantage that it is easy.
Thus, according to the present invention, instead of using a conventional metal square dish or a heat storage dish (Patent Document 1) alone, a metal square dish is inserted between shelves provided on the wall surface of the microwave oven. This is a combination of placing a heat-storing dish in it, and is achieved only by making the dish into a circular dish.

Next, a method of using the pizza cooking utensil according to the present invention, which includes such a metal square dish and a heat storage circular dish housed therein, will be described with reference to FIG.
(1) First, open the door and place a pizza cooker (with a metal square dish and a heat storage circular dish without pizza) on the upper shelf in the upper and lower shelves of the microwave oven (oven mode). Close the door (t0). The reason is that the upper heater is usually a surface heater and the output is larger than that of the lower heater (two sheathed heaters).
(2) Preheat the upper heater by duty heating (t1) (At this time, if the lower heater also participates in the preheating by duty heating, the rise in the internal temperature is accelerated and contributes to the temperature rise of the pizza dish. ).
(3) After about 20 minutes, the circular dish reaches a preliminary completion level Pe of about 220 ° C. to 300 ° C. in temperature (t2). The above is the preheating mode (P0).
(4) Then, the door is opened (O1), the pizza cooking utensil is taken out, the fresh pizza is placed on this, this time stored in the shelf under the oven, and the door is closed (C1). During this time, the time from t2 to t3 usually requires about 1 minute.
When the door is opened / closed, the metal square pan drops rapidly from 60 ° C. to 80 ° C., but it is above the HOT judgment level.

(5) After closing the door (t3), when both the upper heater and the lower heater are duty-heated, the temperature rises to about 140 ° C. within 1 minute (T1). Since the fresh pizza is placed on the circular dish, the heat of the circular dish itself continues to be taken away by the fresh pizza, so that the temperature of the one heated by the lower heater is lowered by about 40 ° C.
(6) Thereafter, for 7 to 8 minutes (t4 to t5), the fresh pizza rises to about 200 ° C., and the cheese on the front side of the fresh pizza is melted by the upper heater. On the other hand, the back side of the fresh pizza (because the heat of the sheathed heater is dissipated in all directions in the metal square dish according to the present invention and becomes uniform in the round dish), it is baked evenly (cooking TCook).
This completes cooking one pizza.

(7) Open the door (O2) and take out the pizza cooker. Furthermore, when cooking another pizza continuously, only the pizza cooking utensil is again stored in the oven shelf, the door is closed (C2), and preheating is started (starting point t6, preheating mode P0).
(8) After about 12 minutes (t6 to t7), the circular dish reaches a preliminary completion level of about 220 ° C to 300 ° C in temperature (t7).
(9) Then, the door is opened (O3), the pizza cooking utensil is taken out, the second raw pizza is placed thereon, this time stored in the oven shelf, and the door is closed (C3). During this time, the period from t7 to t8 is usually about 1 minute.
When the door is opened / closed, the metal square pan drops rapidly from 60 ° C. to 80 ° C., but it is above the HOT judgment level.

(10) After closing the door (t8), when both the upper heater and the lower heater are duty-heated, they are heated in the same manner as in the first cooking. (Cooking TCook). This completes the cooking of the second pizza.
In the following, the same procedure can be applied to the third sheet.

When it sees in this way, it turns out that the length of time differs in preheating time slot | zone t1-t2 and t6-t7. At the time of the first pizza cooking, because the room is at room temperature, the preheating time zone is long, but from the second time the preheating is so hot that it takes too much time to preheat to the desired temperature. is there.
In terms of numerical values, the first preheating time zone is 20 minutes, and the second time is 12 minutes, with the door opening and closing taken as 1 minute. Of course, if the opening and closing time of the door is long, both the metal square dish and the circular dish will drop near room temperature, so it will not be different from the first preheating time zone.

Therefore, according to the second embodiment of the present invention, 1 minute and 45 seconds after the door is opened, a buzzer is sounded (reset in 2 minutes) to promptly close the door. Moreover, it is good to sound a buzzer 20 minutes after the first preheating, and sound a buzzer when cooking is completed 7 to 8 minutes after cooking is completed.
Thus, in order to ensure 1 minute of the opening and closing time of the door, it is a feature that does not sound a buzzer to alert the lapse of 1 minute 45 seconds. Conventionally, only the end of cooking is sounded with a buzzer, but the buzzer is sounded 1 minute 45 seconds after the door is opened.

  As described above, when a plurality of pizzas having a predetermined thickness are continuously baked, the pizza cooking control device sounds a buzzer according to a time sequence of cooking times as a reference. When the thickness of the pizza dough differs, a time sequence of cooking time suitable for cooking the pizza is set, and the buzzer ringing time is adjusted accordingly.

  If the opening and closing of the door after preheating takes longer than a certain time (for example, 3 minutes) on the basis of 2 minutes, the next preheating time will compensate for the temperature drop further than the reference temperature drop. The control unit calculates and automatically extends the preheating time and then sounds the buzzer.

As described above, according to the present invention, pizza cooking that can be easily and easily baked on the entire surface of the crust and the crust surface is crisp, the crust surface is crisp, and the crust is not baked and shrunk. I was able to get the instrument.
In the past, it was the fact that such incompletely baked pizza was eaten as it is, but according to the present invention, the bottom surface of the pizza can be crisply baked in a short time, so the crust surface becomes crispy. The crust interior and ingredients will allow you to eat delicious pizzas that are not baked.
