Description

  The present invention relates to a cooking device including a magnetron that generates microwaves as a heating means for heating food.

  General foods are baked and burnt at 180 ° C or higher, but in food heating using microwaves, water in the food is heated, so the temperature of the food does not exceed 100 ° C, the boiling point of water, Microwave heating could not color the food. Therefore, in the microwave oven equipped with a heater and a magnetron, when cooking food with a brown color, it is heated by radiant heating using a top heater. However, when food is heated by radiant heating of the upper surface heater, both sides of the food cannot be heated at one time.

  Therefore, a cooking device has been developed that heats the food surface to a high temperature by bringing a heating element that absorbs microwaves and generates heat into contact with the food. For example, food is placed on a cooking pan equipped with a heating element that absorbs microwaves and generates heat, and the lower surface of the food that contacts the cooking pan is heated by microwaves and the upper surface of the food is heated by radiation heating with a heater. A vessel has been proposed.

  Moreover, the technique disclosed by the following patent documents is known as a method of cooking both sides of food.

  In Patent Document 1, a heat generating plate made of a ceramic sintered body, a shallow box-like shape having an internal space for accommodating a flat food to be heated, which is made of a heat-resistant synthetic resin and a microwave shielding layer. A cooking device is disclosed in which a microwave absorbing heat generating plate is provided in a container so that the microwave absorbing heat generating plate generates heat by microwaves, and the surface of food in contact with the heat generating plate is heated to a high temperature.

  In Patent Document 2, by heating and cooking in a state in which a plurality of flat plate-like microwave absorption heating elements are erected in a positional relationship so as to face each other, the food is sandwiched between the heating elements. A microwave oven cooking utensil having a structure in which microwaves are evenly absorbed by a plurality of heating elements and cooked foods regardless of which direction the microwaves are irradiated with is disclosed.

  In Patent Document 3, two heating elements each having a heating layer formed on the surface of a base material formed in a mesh shape with a metal core material are connected via a pivotable fulcrum. A heating element for a high-frequency heating device that heats the surface with a heating element and the inside with a microwave is disclosed.

Japanese Patent Laid-Open No. 6-193887 JP-A-9-126474 Japanese Patent Laid-Open No. 11-167985

  In a conventional cooking device, the food is placed on a cooking pan equipped with a heating element that absorbs microwaves and generates heat, and the lower surface of the food is heated by microwaves and the upper surface of the food is heated by a heater. In order to irradiate the placed food with microwaves, the inside of the food may be dried during cooking, resulting in a crisp finish.

  In addition, since the amount of electric power that can be used simultaneously by the cooking device is limited, the high output heater and the high output of the magnetron for raising the surface of the food cannot be used at the same time, and the heater and the magnetron must be operated alternately. Therefore, energy loss is large and thermal efficiency is not good.

  In addition, since the lower surface of the food is brought into contact with the cooking dish and the upper surface of the food is opened, there are cases where the color of the baking is different between the upper surface and the lower surface of the food.

  In Patent Document 1, a ceramic-mixed heating element is used. Since the microwave is absorbed by the ceramic, the heating value of the heating element is small, and it takes a long time to raise the temperature of the food surface. Hard to burn. In addition, when the thickness of the food is thicker than the entire thickness of the container, the space between the containers is opened, the food is not sealed, and the microwave that has passed through the heating element is absorbed by the food and the moisture inside the food is released. The In addition, when the thickness of the food is thinner than the thickness of the lower container, the food and the heating plate are not in contact with each other, and the food is not burnt on both sides. Moreover, since the weight of the upper container is applied to the food, the food is compressed and the finish is deteriorated. In addition, since the microwave shielding layer on the surface of the container is made of a thin metal film, microwaves tend to concentrate on the edge of the microwave shielding layer, and discharge occurs between the edge of the microwave shielding layer and the shielding layer. (Spark) occurs.

  In Patent Document 2, the interval between the heating elements is fixed, and when the thickness of the food is different from the interval between the heating elements, the heating element and the food do not come into contact with each other, and the surface of the food cannot be burnt. In addition, since the food is installed upright, it can cope with food that has a certain degree of hardness, but soft food that deforms when it is raised cannot be cooked.

  In Patent Document 3, since food is forcibly sandwiched between two heating elements, the food is crushed and deformed depending on the thickness and type of the food, and the appearance and texture of the food are impaired. In addition, when it is desired to color only the surface of the food, it is necessary to preheat the food in advance after preheating, but the user touches the high temperature heat generator when the food is sandwiched after preheating. There is a risk of burns. Also, if the food is soft liquid food such as hot cake or crepe dough, or if it is small, the net-like heating element is hard to eat, or the food spills from between the meshes, so cooking is not possible .

  The present invention solves at least one of the above problems.

  The present invention is made to solve the above problems, and in claim 1, a heating chamber for storing food, a cooking container for storing the food, a table plate for placing the cooking container, A magnetron that generates microwaves for heating the food, and the cooking container includes a metal cooking dish and a metal lid, and both the cooking dish and the lid are in contact with the food during cooking. The cooking dish has a heating element that absorbs microwaves and generates heat on its lower surface, the lid has a heating element that absorbs microwaves and generates heat on its upper surface, and a resin around the lid A flange-shaped elastic body that is manufactured and deformable in the vertical direction is provided, and the lid and the cooking dish are in contact with each other via the elastic body.

  According to the present invention, the metal plate brought into contact with both sides of the food is heated to a high temperature, and both sides are heated at the same time without causing excessive drying of the inside of the food, regardless of the thickness of the food. A cooking device capable of cooking can be provided.

FIG. 5 is a perspective view of a cooking device containing the cooking container of Example 1. FIG.

  First, the structure of the cooking container 5 of a present Example is demonstrated using FIG. 1 and FIG.

  As shown in the figure, the cooking container 5 of the present embodiment includes a lid 51 and a cooking dish 53, the food 50 is placed on the cooking dish 53, and the lid 51 is placed on the food 50. It is a structure to be used. The lid 51 includes a heating element 52 and a handle 56 on the upper side, and an elastic body 55 on the periphery. The cooking dish 53 has a heating element 54, a support 58 and metal legs 57 on the lower side. I have.

  The lower surface of the lid 51 and the upper surface of the cooking pan 53 are in contact with the food 50, and the lid 51 and the cooking pan 53 in contact with the food 50 are made of a material having high thermal conductivity, such as stainless steel (SUS) or aluminum. Made of metal. The heating element 52 for the lid and the heating element 54 for the cooking pan are made of a material that absorbs microwaves and generates heat, for example, a silicon resin mixed with ferrite powder. That is, the lid 51 and the cooking pan 53 each have a heating element on one side that contacts the food 50 and does not contact the food 50.

  The handle 56 of the lid 51 is made of a material having low thermal conductivity and difficult to be heated by microwaves, for example, a resin such as polyphenylene sulfide (PPS) or polytetrafluoroethylene (PTFE). Here, in this embodiment, two handles 56 are attached to the left and right sides of the lid 51, but the attachment position and number of the handles 56 can be arbitrarily set, and one handle 56 is provided at the center portion of the lid 51 and the like. It may be provided.

  Moreover, the metal leg 57 is arrange | positioned through the support tool 58 under the cooking pan 53, and installing the cooking tray 53 in appropriate height by mounting in a bottom face through the metal leg 57. FIG. Is possible. The support 58 is made of a resin having low electrical conductivity and high heat resistance, such as a resin such as PPS. Here, the metal legs 57 in the present embodiment are made of metal, but may be made of resin having high heat resistance and high strength.

  Here, in the cooking container 5 of the present embodiment, a flange-shaped elastic body 55 is attached around the lid 51, and the cooking pan 53 and the lid 51 are in contact with each other via the elastic body 55. The elastic body 55 has high heat resistance, hardly absorbs microwaves, does not transmit water vapor, is made of a deformable material, for example, a resin such as silicon, and has a bellows structure that can be elastically deformed in the vertical direction. Further, the elastic body 55 has a flange shape that can be matched with the upper surface of the flange and the side wall surface around the cooking pan 53 at a location where it comes into contact with the cooking pan 53.

  The deformation shape of the elastic body 55 will be described with reference to FIGS. 3 and 4. As described above, the cooking container 5 is placed in contact with the food 50 on the cooking plate 53 provided with the heating element 54, and placed in contact with the lid 51 provided with the lid heating element 52. It is a structure to do.

  Here, as shown in FIG. 3, when the thickness h of the food 50 is larger than the depth d of the cooking pan 53, the food 50 is placed on the cooking pan 53 and the lid 51 is placed on the food 50. After being placed in contact, the flange portion 55a of the elastic body 55 and the flange portion 53a of the cooking pan 53 are brought into contact by holding the elastic body 55 and extending in the vertical direction while the lid 51 is fixed on the food 50. be able to.

  As shown in FIG. 4, when the thickness h of the food 50 is smaller than the depth d of the cooking pan 53, the food 50 is placed on the cooking pan 53 and the elastic body 55 is placed on the cooking pan 53. After installing the lid 51 so as to be along, the elastic body 55 is shrunk in the vertical direction by applying an external force on the lid 51 while the flange part 55a of the elastic body is in contact with the flange part 53a of the cooking pan 53. By pressing down the lid 51, the lid 51 can be brought into contact with the upper surface of the food 50.

  Here, for example, the depth d of the cooking pan 53 is about 10 to 20 mm, and the food thickness h is 20 mm or more, such as bread, and the food thickness h is 10 mm or less. 51 and the cooking pan 53 are brought into contact with both surfaces of the food 50, and the lid 51 and the cooking pan 53 can be brought into contact with each other through the elastic body 55.

  The above is the configuration of the cooking container 5 of the present embodiment. Next, the effect of the present embodiment will be described.

  By storing the food 50 in the cooking container 5 of this embodiment and irradiating microwaves, the heating element 52 of the lid and the heating element 54 of the cooking dish are heated, and the heat is conducted to contact the food 50. The lid 51 and the cooking pan 53 are heated to a high temperature, and both surfaces of the food 50 can be heated to a high temperature.

  Here, as described with reference to FIGS. 3 and 4, the lid 51 and the cooking dish 53 can be brought into contact with the food 50 regardless of the thickness of the food 50, and each heating element is irradiated with microwaves. By generating the heat, both sides of the food 50 can be heated to a high temperature in a short time, and both sides can be burnt simultaneously. Moreover, since the food 50 can be sealed in the cooking container 5 by the elastic body 55 interposed between the lid 51 and the cooking pan 53 regardless of the thickness of the food 50, the evaporation of moisture from the food 50 during cooking is prevented. Can be suppressed.

  Furthermore, since the elastic body 55 is provided with a flange 55a that can be fitted to the upper surface and the side wall surface of the flange 53a around the cooking dish 53 at a location where it comes into contact with the cooking dish 53, the lid 51 cooks the elastic body 55. By placing on the dish 53, the position can be easily adjusted with respect to the cooking dish 53, and the food 50 can be sealed. If the corner portion R of the flange 53a of the cooking pan 53 is smaller than the corner portion R of the flange 55a of the elastic body 55 that comes into contact, the alignment is easier.

  In addition, if the distance between the lid 51 and the cooking pan 53 is sufficiently smaller than the microwave wavelength (12 cm), even if microwaves are radiated from the outside, the microwaves can pass through the gap between the lid 51 and the cooking pan 53 inside the cooking vessel 5. It is hard to invade. Therefore, the surroundings are sealed so that water vapor does not evaporate, and the microwaves are not absorbed, so that excessive drying of the food 50 during cooking can be prevented. That is, by using the cooking container 5 of the present embodiment, regardless of the thickness of the food 50, it is possible to perform cooking that prevents the inside of the food 50 from drying and burns both sides of the food 50.

  Moreover, since the space between the lid 51 and the cooking pan 53 can be adjusted to an arbitrary distance by the elastic body 55, sparking between the lid 51 and the cooking pan 53 can be prevented.

  Further, since no external force is applied to the food 50, even when the food 50 is soft, such as bread, the food 50 can be cooked without being crushed or excessively deformed.

  Further, unlike oven cooking, preheating is not required before cooking, and the handle 56 is made of a resin that is difficult to be heated by microwaves and has low thermal conductivity. Therefore, the lid heating element 52 and the lid 51 are heated to high temperatures after cooking. Even in this case, the lid 51 can be removed safely by holding the handle 56, and can be handled safely.

  In addition, since the cooking pan 53 has a metal dish shape, the food 50 does not spill even when the food 50 is in a liquid state such as okonomiyaki or in a soft state.

  The above is the effect of this embodiment.

  Next, the structure of the heating cooker 1 of a present Example and the structure and effect in the case of performing cooking using the cooking container 5 with the heating cooker 1 are demonstrated using FIG.

  First, in the heating cooker 1 of the present embodiment, as shown in the figure, a heating chamber 3 for storing food is provided inside a cabinet 10 that forms the outer shell of the main body 1 of the microwave oven. An openable / closable door 2 is pivotably provided on the front side.

  The door 2 opens and closes when the food and the cooking container 5 are taken in and out of the heating chamber 3. By closing the door 2, the heating chamber 3 is hermetically sealed to prevent leakage of high frequency used during microwave heating of the food. In addition, the heat of the heater is contained during the oven heating, and the heating can be performed efficiently.

  A detachable table plate 30 having a size and shape close to that of the heating chamber 3 is disposed on the bottom surface of the heating chamber 3, and a heater (not shown) is provided as a heating means for heating the food while keeping the interior at a high temperature. The food stored in the heating chamber 3 can be baked by convection heating or radiant heating with hot air.

  The space below the heating chamber 3 is a machine room 4, which controls a magnetron 41 that generates a microwave having a frequency of about 2450 MHz, a rotating antenna 42 that irradiates the microwave into the heating chamber 3, heating means, heating time, and the like. A control circuit (not shown) is incorporated. The microwave generated by the magnetron 41 is transmitted to the rotating antenna 42 and diffused and radiated into the heating chamber 3 by the rotation driving of the rotating antenna 42.

  A plurality of weight sensors 43 are provided on the upper side of the machine chamber 4, and the removable table plate 30 is supported by a support shaft that penetrates the heating chamber 3, and food is placed on the table plate 30. Then, the weight of the food can be detected by the plurality of weight sensors 43.

  When performing cooking using the cooking container 5 of the present embodiment, the food 50 is first placed on the cooking plate 53 of the cooking container 5. Thereafter, the lid 51 is arranged on the cooking plate 53 so that the elastic body 55 fits the cooking plate 53. In that case, when the food 50 is thick, the lid 51 comes into contact with the upper surface of the food 50 and the elastic body 55 and the cooking pan 53 are separated from each other. Therefore, the elastic body 55 is moved up and down until the cooking pan 53 comes into contact. Stretch in the direction. Further, when the food 50 is thin, the elastic body 55 comes into contact with the cooking pan 53 and the lid 51 and the food 50 are separated from each other. Therefore, the elastic body 55 is shrunk in the vertical direction and the lid 51 is lowered downward. Then, the lid 51 and the upper surface of the food 50 are brought into contact with each other.

  Thus, the cooking container 5 containing the food 50 is placed in the heating chamber 3 of the heating cooker 1 and placed on the table plate 30. When the door 2 is closed and the cooking content is instructed, the weight sensor 43 measures the weight and position of the cooking container 5 and the food 50 via the table plate 30, and the appropriate cooking time is automatically set by the control means. Then, by operating the magnetron 41 and the rotating antenna 42 during the set cooking time, the heating chamber 3 is irradiated with microwaves.

  The microwaves irradiated into the heating chamber 3 are absorbed by the heating element 52 of the lid of the cooking container 5 and the heating element 54 of the cooking dish, so that the lid 51 and the cooking dish 53 are heated to a high temperature. Since the lid 51 and the cooking pan 53 are in contact with the food 50, the upper surface of the food 50 is heated to a high temperature from the lid 51, and the lower surface is heated to a high temperature from the cooking pan 53. In addition, the microwave does not easily enter the cooking container 5, and the food 50 is surrounded by the cooking plate 53, the lid 51, and the elastic body 55. The both sides of the food 50 can be burnt while retaining moisture.

  Further, since the elastic body 55 is interposed between the lid 51 and the cooking pan 53 and the elastic body 55 and the cooking pan 53 are easily aligned, the horizontal interval between the lid 51 and the cooking pan 53 is set at an appropriate interval. Even when the food 50 is too thin or when an external force more than necessary is applied to the lid 51, the vertical gap between the cooking pan 53 and the lid 51 is set to an appropriate distance (generally, approximately 50 mm or more). 5 mm or more), contact between the cooking pan 53 and the lid 51 and sparking can be prevented.

  Here, if the outer shape of the lid 51 is larger than the outer shape of the cooking pan 53, the lid 51 is caught by the flange around the cooking pan 53, and therefore the distance between the lid 51 and the cooking pan 53 cannot be made smaller than the depth d of the cooking pan 53. However, in the present embodiment, the lid 51 and the food 50 are heated even when the food 50 having a food thickness h smaller than the depth d of the cooking pan 53 is heated because the outer shape of the lid 51 is smaller than the outer shape of the cooking pan 53. It is possible to make the upper surface of the contact.

  Further, if the elastic body 55 is a material or structure that is easily deformed so as to be deformed by its own weight, when the cover 51 is placed on the food 50 placed on the cooking pan 53, the elastic body 55 is formed by the dead weight of the cover 51. 55 is automatically deformed, so that the operator does not need to work to extend and contract the elastic body 55 in the vertical direction as described above, and the lid 51 and the food 50 are simply placed on the food 50. It is also possible to automatically bring the elastic body 55 and the cooking pan 53 into contact with each other. Further, even when the lid 51 is deformed by its own weight, the gap between the lid 51 and the cooking pan 53 can be kept at an appropriate interval (approximately 5 mm or more), and contact between the cooking pan 53 and the lid 51 and sparking can be prevented.

  Further, at the end face of the lid 51, a U-shaped elastic body 55 sandwiches the lid 51, and the elastic body 55 is fixedly supported on the lid 51 by the elasticity of the elastic body 55 itself. The elastic body 55 can be removed from the lid 51, and the lid 51 and the elastic body 55 can be kept clean by removing and cleaning.

  Further, the metal lid 51 and the cooking pan 53 are made of the same kind of metal or a metal having a coefficient of linear expansion, so that even if the cooking container 5 becomes hot and thermally expands, It is possible to prevent the lid 51 from floating and the spark between the lid 51 and the cooking pan 53 without shifting the positional relationship of the cooking pan 53.

  Therefore, the heating cooker 1 and the cooking container 5 of the present embodiment prevent excessive drying inside the food 50 regardless of the thickness of the food 50 as long as the thickness of the food 50 is a certain level or more. It is possible to provide a heating cooker that can perform heating cooking that heats the food to a high temperature without causing sparks.

  6 is a perspective partial cross-sectional view of the cooking container of Example 2 as viewed from the upper surface side. FIG. 7 is a perspective view of a cooking device containing the cooking container according to the second embodiment. In addition, the present Example 2 uses the heating cooker 1 similar to Example 1, and abbreviate | omits description about a common structure.

  The structure of the cooking container 5 of a present Example is demonstrated using FIG.

  The cooking container 5 of this embodiment supports a heating element 52 and a handle 56 on the upper side, a lid 51 having an elastic body 55 on the periphery, and a cooking dish heating element (not shown) on the lower side. The cooking plate 53 is provided with a tool 58. The support tools 58 are provided at both the left and right ends of the cooking pan 53, and are made of a material that hardly absorbs microwaves and has high heat resistance, such as PPS.

  With the above-described configuration, the cooking container 5 of the present embodiment performs cooking by irradiating microwaves with the heating cooker 1 with food sandwiched between the lid 51 and the cooking pan 53, as in the first embodiment. Thus, both sides of the food can be heated to a high temperature while preventing the food from drying.

  The structure in the case of cooking with the heating cooker 1 using the cooking container 5 of a present Example is demonstrated using FIG.

  A shelf 31 is installed on the wall surface of the heating chamber 3 inside the cooking device 1.

  In this embodiment, since the left and right ends of the cooking dish 53 of the cooking container 5 are provided with resin support tools 58, the support tool 58 is brought into contact with the shelf 31 on the wall surface of the heating chamber 3, and the cooking container is placed on the shelf 31. 5 can be placed.

  Here, since the shelf 31 is made of metal like the wall surface of the heating chamber 3 and the support tool 58 is made of resin, the support tool 58 has an appropriate distance between the cooking pan 53 and the wall surface of the heating chamber 3 (approximately 5 mm or more). Therefore, no spark is generated between the cooking pan 53 and the wall surface of the heating chamber 3, and the cooking container 5 of this embodiment can be placed in contact with the shelf 31 inside the heating chamber 3.

  Moreover, if the wall surface of the heating chamber 3 is provided with a plurality of shelves 31 having different heights as shown in the figure, the cooking container 5 is changed in height (distance from the bottom surface of the heating chamber) according to cooking. It is also possible to do.

  In the present embodiment, microwaves are radiated from the rotating antenna 42 below the table plate 30 on the bottom surface of the heating chamber 3. Therefore, the microwaves absorbed by the respective heating elements are changed by changing the distance between the rotating antenna 42 and the cooking vessel 5. You can adjust the amount and change the finished state.

  For example, if you want to cook with a similar baked color on both sides of the food, such as bread toast or okonomiyaki, and darken the baked color on one side of the food, such as dried fish or grilled fish. If you want to, the heating balance of the upper and lower surfaces of the food is different. In the cooking container 5 of the present embodiment, the temperature of the lid 51 and the cooking pan 53 is raised in the same manner by using the high shelf 31 and setting the height of the cooking container 5 high to perform cooking. The same baking color is set, the cooking container 5 is set to a low height, and cooking is performed, whereby the temperature of the cooking pan 53 is set higher than the temperature of the lid 51 and the baking color of the lower surface of the food is darkened. Can do.

  FIG. 8 is a perspective partial sectional view of the cooking container of Example 3 as viewed from the upper surface side. FIG. 9 is a perspective view of a cooking device containing the cooking container of Example 3. In addition, the present Example 3 uses the heating cooker 1 similar to Example 1, and abbreviate | omits description about a common structure.

  The structure of the cooking container 5 of a present Example is demonstrated using FIG.

  The cooking container 5 of the present embodiment has a lid heating element 52 and a handle 56 on the upper side, a lid 51 having an elastic body 55 around it, a cooking dish heating element (not shown), a resin leg 59 and a metal on the lower side. It is comprised by the cooking pan 53 provided with the leg 57, and it is possible to heat both surfaces of a foodstuff at high temperature and to make a baked color by heating and cooking by putting a foodstuff between the cover 51 and the cooking pan 53. is there.

  The resin legs 59 are made of a material that hardly absorbs microwaves and has high heat resistance, for example, resin such as PPS, and is fixed to the lower portion of the cooking pan 53. Further, the metal legs 57 are rotatably attached to the lower part of the cooking pan 53, and the cooking container 5 can be placed on the bottom surface via the metal legs 57 in the state in which the metal legs 57 are widened, as in the first embodiment. When the metal legs 57 are folded, the cooking container 5 can be placed on the bottom surface via the resin legs 59 as shown in the present embodiment. Therefore, in the cooking container 5 of a present Example, the height of the cooking container 5 can be adjusted in two steps by changing the leg which contacts a bottom face by the folding method of the metal leg 57. FIG.

  The structure in the case of cooking with the heating cooker 1 using the cooking container 5 of a present Example is demonstrated using FIG.

  When the metal legs 57 are folded, the cooking container 5 of the present embodiment can be placed on the table plate 30 via the resin legs 59 as shown in FIG. Therefore, in a structure in which the table plate 30 is supported by a weight sensor (not shown), the weight of the cooking container 5 can be measured via the table plate 30.

  Similarly to the second embodiment, in the case of a heating cooker that includes a rotating antenna 42 under the table plate 30 and irradiates microwaves from the rotating antenna 42, the distance from the rotating antenna 42 of the cooking container 5 is changed. By arranging, the ratio can be adjusted to the amount of microwaves absorbed by the lid heating element 52 and the cooking dish heating element 54, so that the temperature of the lid 51 and the cooking dish 53 should be the same, or the lid 51 and the cooking dish For example, when it is desired to make a difference in the temperature of 53, it is possible to perform cooking by changing the finished state of the food.
