Description

  The present invention relates to a heating cooker that steams food.

  Conventionally, many cooking utensils of this type have been proposed as cooking utensils for supporting cooking of an object to be heated in a heating cooker room.

  2. Description of the Related Art Conventionally, a high-frequency heating apparatus heats food (a heated object) from the inside in a short time by microwaves generated from a magnetron. However, without directly heating the food with microwaves, water was heated with microwaves, and cooking utensils that heated the food using the generated water vapor and heating elements that generated heat by microwave absorption were adhered. It is known that food is placed on a cooking pan, and the surface of the food that is in contact with the saucer is made hot by microwaves and the surface of the saucer is heated.

  In Patent Document 1, food is placed on a food placing surface (a saucer) of a main body formed of a semiconductor that absorbs microwaves and generates heat, and water is poured into a recess provided on the food placing surface to irradiate microwaves. Thus, there is described a steaming pan for a microwave oven in which food in contact with the food placing surface is burned and burnt, and the water placed in the recess is boiled to steam the food.

  Next, Patent Document 2 discloses that a cooking stove plate having a heating element (a high-frequency heating element) that absorbs microwaves and generates heat as a cooking utensil for supporting food cooking can store water. The structure in which the water stored in the microwave oven is heated by the microwave and the heat of the heating element to generate steam is described.

  In addition, the cooking stove has a cooking surface on which food is placed, and the cooking surface has a metal food placing table having a through hole through which steam passes, and the food on the food placing table is covered. And a lid (lid body) made of a material that does not transmit microwaves.

  From the above structure, the effect of Patent Document 2 is not to generate steam only by the microwave heating, but also to heat the steam water by adding heating by the heating element that generates heat by the microwave heating. It is described that the time until steam is generated can be shortened, the steam cooking time can be shortened, and an easy-to-use steam cooker can be realized.

  In recent years, heating cookers that can cook efficiently, reduce cooking time without taking time, and can cook more deliciously are preferred.

  However, the steaming pan for microwave oven shown in Patent Document 1 described above directly heats food with microwaves simultaneously with the start of heating. Therefore, in the case of dumplings described in the examples, the seam portion of the skin confining the ingredients Since it is heated by microwaves before being steamed with steam, it is dried and hard cooked (once it has been cooked in a dry state, it does not become soft even after steaming) and is not very delicious. In addition, since the temperature of the food placement surface is deprived of heating the water, the temperature of the food placement surface cannot be kept high while water is present. Conversely, when steam is required, it is necessary to maintain the food placement surface at a constant temperature, and thus there is a problem that the necessity and necessity of steam and the temperature of the food placement surface cannot be freely controlled individually.

  Moreover, about what was shown by patent document 2, although the lid | cover is formed from the material which does not permeate | transmit a microwave, the microwave oven pan which has a heat generating body uses the material (ceramic) which permeate | transmits a microwave. Yes. Furthermore, it is set as the structure which a microwave can penetrate | invade between between a lid | cover and a food mounting stand so that a vapor | steam can generate | occur | produce at an early stage the water stored in the microwave oven.

  Because of these structures, the microwave that has entered the lid is absorbed by the food before the water stored in the microwave oven becomes steam, so that the food (especially dumplings, Shumai, etc.) The surface of the skin wrapped food) is not dry and delicious.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. In claim 1, a steam generating means in which a heating chamber for storing an object to be cooked and a steam outlet for discharging steam into the heating chamber are faced.

In addition, the object to be heated can be steamed without drying the central portion and the like.

  In addition, since the saucer on which the object to be heated is placed has the high-frequency heating element, the saucer generates heat by the microwave generated from the magnetron and can heat the surface and the inside of the object to be heated. It becomes.

  Furthermore, since the lid and the tray are made of a metal material that does not transmit microwaves, the object to be heated does not directly absorb microwaves.

  As a result, it is possible to cook full-fledged steamed dishes and baked dishes with good finish, and since the lid and the saucer are in a sealed state, moisture generated from the object to be heated Since it does not adhere to the heating chamber or the like, there is an effect that it is possible to improve usability.

Before Kifutatai is formed by a metallic material which does not transmit the microwave generated from the magnetron, the lower periphery of the lid, so as not to transmit the pan heat the lid, silicone rubber gasket Is provided.

  As a result, the lid itself does not generate heat due to microwaves, and further suppresses the transmission of heat generated from the saucer, so that the lid is less likely to have heat during cooking.

According to Claim 2 of this invention, the to-be-heated material mounting surface of the said saucer and the said saucer direction surface of the said cover are fluorine-coated.

  Thereby, in a saucer, there exists an effect that reduction of sticking of a to-be-heated material can be aimed at.

  A present Example consists of the above structure, and demonstrates the operation | movement example in the case of making a dumpling steamed as the to-be-cooked object 130 about operation | movement next.

  As shown in FIG. 11, the dumplings of the object to be cooked 130 are arranged on the tray 111 and covered with the grill pan lid 101, and the steam outlet 102 is directed to the steam outlet 44 and placed on the table plate 24 of the heating chamber 28 as shown in FIG. Put.

  For the heating of the dumplings, a process that has been confirmed in advance is input to the control means 151, and the heating time is adjusted according to the weight detected by the weight detection means 25.

  For heating, steaming of dumplings is selected from automatic cooking already input by the input means 71, and heating is started by pressing a heating start button (not shown).

  Heating proceeds in the control process shown in FIG.

  The dumpling cooking control 200 includes a steam heating steam step 201 by the steam generating means 43, a steam + range step 202 having both steam heating and microwave heating by the range heating means 77, and a microwave heating range by the range heating means 77. This is control for performing the three-stage process of the process 203.

  The steam process 201 is a heating process in which the control means 151 steams the dumplings with steam only by the steam generating means 43, and steams the surface portion of the cooking object 130, particularly the skin portion, and then gradually. Steam the ingredients inside.

  In the state of the steam process 201, the inside of the tray 111 in which the dumplings are present and the grill pan lid 101 are filled with water vapor ejected from the steam outlet 44. The filled water vapor steams the dumpling skin and the internal ingredients, and a part of the water vapor accumulates in the tray 111 as condensed water. A lid packing 104 is provided on the lower peripheral portion of the grill pan lid 101 so that the water vapor filled at this time does not leak from the tray 111 and the grill pan lid 101. This reduces the amount of water vapor leaking into the heating chamber 28, eliminates cleaning of the heating chamber 28, and improves usability.

  The steam + range step 202 is a heating step in which the control means 151 combines the steam heating of the steam generation means 43 and the microwave heating of the range heating means 77, and the entire dumpling which is the cooking object 130 is steamed 201. Similarly, the high-frequency heating element 120 on the back surface of the metal dish part 112 of the tray 111 absorbs the microwave emitted from the magnetron 33 and generates heat, thereby transferring heat to the metal dish part 112. Thereby, while steaming the whole dumplings, the effect of so-called steaming can be achieved, in which the back surface of the dumplings in contact with the surface of the metal dish portion 112 is burnt and burnt.

  In the steam + range process 202 state, the saucer 111 in which the dumplings are present and the inside of the grill pan lid 101 are heated from the saucer 111 while being filled with water vapor ejected from the steam outlet 44. It has become. At this time, the surface temperature of the saucer 111 is heated to a temperature equal to or higher than the temperature of water vapor (about 100 ° C.), and the water accumulated in the saucer 111 becomes steam again to steam the dumplings. Originally, the heat of the tray 111 heated by the range heating means 77 is also transmitted to the grill pan lid 101, but the grill pan lid 101 is formed of a metal material that does not transmit microwaves. In addition, since the heat of the tray 111 is not transmitted by the lid packing 104 provided on the outer periphery of the lower end of the grill pan lid 101, the structure of the grill pan lid 101 itself has a structure that hardly heats during cooking by the range heating means 77. Yes.

  During the state of the range process 203, the canopy is in a state of generating heat from the tray 111 on which the dumplings are placed. In the tray 111 and the grill pan lid 101, the remaining water collected in the pan 111 becomes steam and steams the dumplings, so that condensation is promoted on the surface of the grill pan lid 101. The saucer 111 heated by the range heating means 77 can be burnt while baking the back side of the dumplings.

  Further, since the rise of the surface temperature of the grill pan lid 101 is suppressed, condensation can be promoted on the surface of the grill pan lid 101. After cooking, the grill pan lid handle 103 provided on the upper portion of the grill pan lid 101 is improved. Since the temperature is not high, when the dumplings are taken out from the main body 1, the grill pan lid handle 103 can be easily grasped.

  Further, the weight of the dumplings placed on the grill pan lid 101 is measured by the control means 151 by the weight detection means 25 provided at the bottom of the table plate 24, and the steam process 201, the steam range process 202, and the range process 203 are measured. It is possible to adjust the time.

  Moreover, when the optimal cooking process in the cooking of the dumpling in a present Example is represented by time ratio, from the time table of FIG. 14, from the total time (t0) of a cooking process, time (t1) of a steam process 201: Steam range The time ratio of the time (t2) of the process 202: the time 203 of the range process (t3) is 10: 7: 3.

  As described above, according to the present embodiment, when the dumplings are steamed, it is possible to eliminate the drying of the surface of the skin-wrapped dishes such as dumplings and shumai that trap the ingredients, and to make the cooking finish in a moderate state.
