Description

  The present invention relates to a cooking device having functions such as microwave heating and oven heating.

  In a conventional microwave oven that is this type of cooking device, microwave heating by magnetron oscillation, oven heating by an electric heater, or the like is selected and used depending on the food cooking method in the heating chamber.

  Also, recent microwave ovens include steam and superheated steam as heat sources other than microwaves and heaters, and various heat cooking can be performed by combining these heat sources.

  In a turntableless microwave oven that does not have a table for cooking while rotating food placed in the heating chamber, in the case of microwave heating, food is placed directly on the bottom of the heating chamber or in a container.

  In microwave heating in conventional microwave ovens, the microwave oscillated from the magnetron forms a standing wave in the heating chamber, so that even if the antenna rotates, the intensity of microwave energy is generated in the chamber, causing uneven heating of food. It has become a cause.

  In addition, since the waveguide for transmitting the microwave energy to the heating chamber is disposed along the outer wall of the heating chamber, the waveguide is not symmetric with respect to the microwave irradiation surface of the heating chamber. For this reason, the standing wave in the heating chamber is directional regardless of the food load or the presence or absence of the antenna. Therefore, the rotating antenna in the turntableless microwave oven only serves to alleviate this directivity.

  In addition, since the food itself placed in the heating chamber is a factor that changes the standing wave, it is difficult to efficiently irradiate microwaves only to the food. It is difficult to reduce power consumption during cooking and shorten cooking time.

  On the other hand, the hot air blowing port by the hot air circulating device in the hot air circulating oven and the steam supply port to the heating chamber by the steam generating device such as boiler are thermally only from one wall surface of the heating chamber in which those devices are installed. The structure which acts is common, and it heats only from one direction with respect to a foodstuff, and it becomes easy to produce a heating nonuniformity by the influence of a heat source position and a foodstuff position.

  This also changes depending on the distance from the apparatus to the food, that is, the position of the food in the heating chamber. The farther the food is from the hot air or the steam outlet, the worse the heating efficiency of the food.

  In the configuration described in Patent Document 1, since the container and tray are positioned in a rotary table type heating cooker, the container position is generally at the center of the heating chamber serving as the rotation axis of the rotary table. Since the container on the turntable is heated while being rotated, the heating is always stable. However, since the heating pattern is uniform, the effect of concentrated heating or combined heating with a plurality of heat sources is difficult to obtain. That is, the influence of the heating efficiency on the position of the heating chamber is not considered.

  Further, since the tray and the container are stacked on the rotating tray, it is difficult to align the respective positions.

  In recent years, it has not been configured to be compatible with a turntableless microwave oven that is a general configuration.

  Therefore, this container and tray are not dependent on the size or shape of the heating chamber of the heating cooker other than the saucer, and are intended for the safety and stability of the container, such as control of overflow in the container, There is no clear indication such as the arrangement of heating chambers that can perform efficient heating, and handling procedures such as container insertion and removal.

  Moreover, this container and tray are separate attached cooking utensils which can be used for a heating cooker, and there is no effect | action related to a heating cooker. That is, the presence or absence of the container (load) cannot be detected, and when the load is small, the container may be melted or ignited, so the safety is not necessarily good.

  In the configuration described in Patent Document 2, since it is installed on a designated shelf in a square plate, it cannot be applied to microwave range heating in which discharge or spark occurs between metals. In addition, the space separation of the heating chamber by the shelf is often difficult to perform heating combining a plurality of heat sources, such as when there is another heat source such as steam in the space under the shelf.

  In the configuration described in Patent Document 3, an aluminum accessory pan is detachably attached to a dedicated glass cooking pan. When baking, the attached pan is fitted in the dedicated pan and then a stirring blade. The members are mounted inside, and the dough is baked after setting the dedicated cooking pan and attached pan instead of the turntable of the main body of the heating cooker. However, like patent document 1, the glass-made cooking pot is arrange | positioned using the axis | shaft of a rotary table, and a cooking pot is the approximate center position of a heating chamber. Therefore, although cooking control is performed with a limited heating pattern and blade driving, the cooking pan is not necessarily arranged efficiently. In addition, it is an accessory that is difficult to handle due to its weight because it is attached to and removed from the heating chamber in a state where a glass cooking pan and an aluminum pan are stacked. Moreover, since it is attached to the drive shaft in a narrow heating chamber and is difficult to see, it is not easy to use.

  The present invention has been made to solve at least one of the above problems.

  In order to solve the above-mentioned problems, the present invention provides a heating cooker according to claim 1, wherein a heating chamber for cooking an object to be heated, a door for opening and closing a front opening of the heating chamber, and a plurality of heating chambers are heated. Heating means, control means for controlling the heating means, and a resin plate that is installed on the bottom surface of the heating chamber and has a hole or a recess for placing the object to be heated. The placement position of the object to be heated is limited by the recess.

  Further, in the heating cooker according to claim 7, a heating chamber for cooking the object to be heated, a door for opening and closing a front opening of the heating chamber, a plurality of heating means for heating the heating chamber, and the heating means A control unit for controlling, a hole part for placing and heating the object to be heated at a limited position of the heating chamber, and a cooking container for cooking by heating by installing in the hole part, the bottom part of the cooking container being It consists of a resin part.

  By easily arranging the object to be heated at a position where it can be heated most efficiently in the heating chamber according to the cooking menu, it is possible to reduce energy loss and shorten the cooking time or expand the cooking menu.

  A steam generator 87 for supplying steam is provided on the side wall of the heating chamber 7. A water tank 88 supplied by the user is detachably provided below the main body.

  With the above configuration, the microwave oven according to the present embodiment includes a microwave range heating function, an oven heating function using an electric heater, a grill heating function, and a steam heating function using water vapor.

  The resin plate 2 shown in FIG. 3 can be stored in the microwave oven of FIG. 1 and is used by being placed on the bottom surface of the heating chamber 7, that is, on the table 70. The resin plate 2 is formed with one or more holes 21a and 21b, and a container or a food to be heated is placed in the holes 21a and 21b, and cooking according to the menu is performed. In addition, although the structure which provides a hole part in the resin plate 2 is illustrated here, it is good also as a structure which replaces with a hole part and provides a recessed part.

  The resin plate 2 is preferably made of a material such as PTFE (polytetrafluoroethylene) that has a high heat resistance and is difficult to be heated by microwaves, but PEEK (polyether ether ketone) and PPS (polyphenylene sulfide), which have high heat resistance, are practical. is there. In consideration of removal, the plate is preferably made of resin, but may be made of glass or ceramics. In other words, a plate that is frequently attached and detached is suitable for being light and difficult to break even when dropped, and can be easily and accurately shaped, so that positioning within the heating chamber 7 becomes easier.

  In addition, the outer shape of the illustrated resin plate 2 is substantially the same as the width and depth of the heating chamber 7, the left-right direction of the resin plate 2 is fitted to both side walls of the heating chamber 7, and the front-rear direction of the resin plate 2 is heated. The resin plate 2 is aligned by fitting the back wall of the chamber 7 and the door 8. Accordingly, even if the resin plate 2 is repeatedly attached and detached, the holes 21a and 21b of the resin plate 2 are always arranged at a limited position on the bottom surface of the heating chamber 7, and the heated object 1 arranged in the hole always has the same heating conditions. Cooking is done.

  As shown in FIG. 2, a plate detection means 77 using a contact sensor such as a microswitch or a non-contact sensor such as infrared rays is used at the side surface of the heating chamber 7 which is hidden when the resin plate 2 is placed. The presence or absence of the plate 2 can be detected. Since the operation and output of each heating function can be controlled by the presence / absence of the resin plate 2 by the plate detecting means 77, the resin plate 2 and the like are prevented from being melted or ignited in advance, and higher safety is ensured.

  The illustrated resin plate 2 has a rectangular shape and can be stored in the heating chamber 7 in a total of four modes of front / reverse reversal and front / reverse reversal. Therefore, the installation state of the resin plate 2 is detected from a plurality of plate detection means 77. May be.

Needless to say, a combination of the edge 20 and the handle becomes a more convenient cooking accessory.

  Next, cooking according to this embodiment when using range heating will be described.

  The resin plate 2 of the present embodiment is disposed on the bottom surface of the heating chamber 7 with the door 8 open. Then, it becomes the procedure which mounts the to-be-heated material 1 according to the hole part of the resin plate 2. FIG. Microwaves generate electromagnetic waves in the heating chamber 7 due to standing waves. However, since the holes 21a and 21b are arranged at positions where the microwaves are concentrated, the holes 21a and 21b are installed. The heated object 1 can be efficiently heated in a short time.

  The main body instructed to cook via the operation panel 80 first drives the magnetron 59 and the antenna 57.

  The microwave irradiated into the heating chamber 7 is diffused by the rotation of the antenna 57, and the microwave distribution (standing wave) in the heating chamber 7 varies according to the rotation of the antenna 57. By the control, the microwave of the heating chamber 7 can be more concentrated in the hole. Furthermore, if a steam generator 87 for supplying steam is provided near the hole, steam cooking can be performed in a short time by combining these heat sources. Moreover, even if it arrange | positions a hole part in the position where a hot air circulation port 90 has a big air volume, or the position where a hot hot air blows off, it can heat efficiently and can cook with high energy-saving performance.

  The microwave oven of Example 2 is demonstrated using FIG. FIG. 6 is a perspective view of the microwave oven according to the second embodiment when viewed from diagonally right above, in which another resin plate 2 is disposed in the heating chamber 7 according to the first embodiment.

  In the present embodiment, the object to be heated 1 is easily and surely guided to the hole 25 in the heating chamber 7 with the resin plate 2 provided with the hole 25 on the back side of the heating chamber 7. Here, as shown in the figure, it is desirable that the article to be heated 1 is placed in a container so that the guide portion 25a can be slid and carried. Moreover, if the guide part 25a inclines a bottom face toward the back | inner side from a main body near side, usability will become more favorable. Further, if the front side of the main body is made wider than the width of the hole portion 25, the article to be heated 1 can be guided to the hole portion 25 more easily. In addition, what is necessary is just to design the width | variety, depth, a position, etc. of the guide part 25a suitably according to the characteristic and ease of use of a microwave oven. Moreover, if the to-be-heated material 1 can be guide | induced to the position limited with the edge of a guide part, it is not necessary to provide a hole part.

  The microwave oven of Example 3 is demonstrated using FIG.7 and FIG.8. FIG. 7 is a perspective cross-sectional view of the microwave oven of Example 3 as viewed obliquely from the upper left, and FIG. 8 is a side cross-sectional view thereof. Of the configurations of the third embodiment, the description of the configurations common to the first embodiment will be omitted.

  The microwave oven of the present embodiment is configured such that a detachable table 70 is disposed on the bottom surface of the heating chamber 7 and the table 70 is supported by three weight sensors 6. In this microwave oven, the table 70 can be properly used by placing the table 70 in the heating chamber 7 by range heating, removing the table 70 by oven heating, and placing the square dishes on the shelves 71a and 71b.

  Note that this embodiment is directed to a microwave oven to which the table 70 can be attached and detached, and this embodiment does not depend on the number and arrangement of the weight sensors 6 and the weight detection method.

  In the heating chamber 7 to which the table 70 can be attached and detached, the antenna cover 56 is disposed so that the antenna 57 is not exposed with the table 70 removed. The antenna cover 56 is made of a mica plate that easily transmits microwaves, but glass or ceramic may be used.

  In the structure of the present embodiment, the resin plate 2 described in the first and second embodiments is disposed on the bottom surface from which the table 70 is removed. In this case, since the bottom surface of the heating chamber 7 is a metal surface excluding the antenna cover 56, a structure in which the resin plate 2 is observed from the machine chamber 5 side of the bottom surface using the plate detecting means 77 can be applied. Since the machine room 5 has a larger space than the inside of the cabinet 81, a structure for detecting a plate can be easily installed. Further, since the interior of the machine room 5 is cooled by the fan device 4, stable detection is facilitated.

  Further, in the heating chamber 7 of the present embodiment, the positioning of the resin plate 2 is not limited to the side wall surface of the heating chamber 7, and the depression on the bottom surface and the opening by the plate detecting means 77 are used in combination with the unevenness of the resin plate 2. You can also. Therefore, the present embodiment can be applied with a structure that minimizes the size of the resin plate 2 to the minimum necessary without making the size of the resin plate 2 substantially the same as the bottom surface of the heating chamber 7. Here, the necessary minimum is an area composed of a hole and a guide.

  Even in the microwave oven of the present embodiment, the resin plate 2 may be used on the table 70 as in the case of the first embodiment, and the fitting portion is configured by the table 70 and the resin plate 2. The resin plate 2 may be positioned.

This microwave oven includes a rotating shaft 58 protruding substantially in the center of the heating chamber 7, and a turntable type that heats the object 1 while rotating a heated table 1 by arranging a circular table (not shown) on the rotating shaft 58. It is a microwave oven. The machine room 5 is provided on the right side of the heating chamber 7 and houses components such as the magnetron 59 as in the first embodiment. Since the role of each component is the same as that of the first embodiment, description thereof is omitted.

  Since the microwave is supplied to the heating chamber 7 of this embodiment from the side surface, the antenna 57 is not provided below the heating chamber 7. However, the protruding rotating shaft 58 constitutes a part of the heating chamber 7. In this embodiment, the rotation shaft 58 is used for positioning the resin plate 2 and a positioning hole 29 is provided at the approximate center of the resin plate 2.

  In FIG. 9, the outer shape of the resin plate 2 is matched to the size of the bottom surface of the heating chamber 7, but the positioning in the heating chamber 7 can be performed by the positioning hole 29 and one end of the outer shape of the resin plate 2. Therefore, the hole 21b of the resin plate 2 is also easily provided at the target position, and the object to be heated 1 can be cooked efficiently as described above.

  The microwave oven of Example 5 is demonstrated using FIGS. 10-12. In this embodiment, a stirring drive means 60 is arranged on the bottom surface of the heating chamber 7 of the microwave oven of the third embodiment in which the table 70 can be attached and detached, and the cooking container 10 connected to the rotating shaft of the stirring drive means 60 has a stirring function. It can be added. FIG. 10 is a perspective cross-sectional view of the microwave oven of Example 5 as viewed obliquely from the upper left, FIG. 11 is a perspective view showing the storage state of the resin plate 2 in FIG. 10, and FIG. It is a front section of a state. Of the configurations of the fifth embodiment, the description of the configurations common to the third embodiment will be omitted.

  In the present embodiment, a stirring motor 61, a speed reduction means 65, and a sales expansion drive means 60 are provided in the vicinity of the side wall of the machine room 5 opposite to the magnetron 59. Then, the driving force of the stirring motor 61 is transmitted to the stirring driving means 60 that penetrates the bottom surface of the heating chamber 7 via the speed reducing means 65 that decelerates the driving force of the stirring motor 61, and is connected to the stirring driving means 60. The stirring blade 62 of the cooking container 10 is driven to rotate.

  As shown in FIG. 11, in the heating chamber 7, the resin plate 2 is arrange | positioned so that the stirring drive means 60 of the heating chamber 7 bottom face which removes and exposes the table 70 may be covered. The resin plate 2 is set on the bottom surface of the heating chamber 7 along the side wall of the heating chamber 7. After setting, the resin plate 2 is positioned so that the through hole 26 is disposed on the same axis as the stirring drive means 60. The positioning may be performed by using a positioning convex portion, concave portion or side wall surface on the bottom surface of the heating chamber 7. The cooking container 10 is slid from the front toward the hole portion 26 by the guide portion 26a of the resin plate 2 previously stored and installed in the heating chamber 7. Further, as shown in the figure, the cooking container 10 provided with the handle 12a is combined with the resin plate 2 configuration of the present embodiment, so that the cooking container 10 can be more easily connected to the stirring drive means 60 via the guide portion 26a. Needless to say.

  Moreover, in order for the cooking container 10 of a present Example to be connected with the stirring drive means 60 with high torque, a metal part is required for a connection part. In FIG. 11, a resin portion 11 is arranged on a metal pan case 12 and an outer periphery below the pan case 12. By providing the resin part 11 at the bottom of the cooking container 10, the heat insulation on the bottom side of the pan case 12 during cooking is enhanced, and the resin plate 2 is directly scratched or worn when the guide part 26 a is slid. Can be prevented.

  As described above, in the heating chamber 7, for example, the cooking container 10 having the stirring blade 62 that rotates while being connected to the stirring driving means 60 that stirs the bread dough as the article to be heated 1 is attached to and detached from the stirring driving means 60. Provided possible. In the present embodiment, the ingredient charging unit 13 is further arranged on the cooking container 10, and the ingredients (other heated objects) put in the ingredient charging unit 13 in the cooking process are suitable for cooking. It was set as the structure which can be dropped in the cooking container 10 with the input switch 63. FIG. As long as the input switch 63 is a mechanism for removing the material holding of the material input unit 13, a solenoid, a link with motor rotation, or the like may be used. The cooking container 10, the stirring blade 62, and the condition input unit 13 can be removed from the stirring driving means 60 and handled separately, for example, washed and stored. Further, as an example of the speed reduction means 65, for example, a belt may be wound between large and small pulleys provided between the stirring motor 61 and the stirring driving means 60, or the small gear and the large gear may be engaged. Good.

  The baking of the dough is a process of baking the dough at a high temperature of about 180 to 250 ° C. and coloring the baking dough. The cooking vessel 10 and the inner dough are heated from the hot air outlet 90 using the upper heater 50 and the hot air unit 9. The bread dough can be baked by heating using the hot air that is ejected. It is possible to heat and bake the cooking container 10 using microwaves by attaching a heating element that absorbs microwaves to the cooking container 10, but the bread dough absorbs microwaves and the bread dough inside is dried. Therefore, it is more desirable to appropriately combine with heating with a heater. Here, by using the metal pan case 12 having good heat conductivity, heating the cooking container 10 by convection heating and convection heat transfer for blowing hot air from the hot air outlet 90 into the heating chamber 7, thereby heating unevenness. This makes it possible to perform baking cooking with reduced heating time.

  Therefore, since a series of operations can be performed from kneading to baking of the dough simply by putting the dough material into the cooking container 10, it is possible to automatically bake and cook the bread.

  Or you may heat the to-be-heated material 1 other than bread dough as the cooking container 10. FIG. The cooking container 10 need not be all metal as long as the power of the agitation driving means 60 and the agitation blade 62 are sufficiently transmitted and the object 1 to be heated can be agitated. For example, only the transmission part with the stirring drive means 60 inside the resin part 11 may be made of metal, and the pan case 12 may be made of glass through which microwaves pass. Since the heating / cooking method can be changed depending on the material of the bread case 12, a plurality of cooking containers 10 may be attached.

  As an example, when the stirring blade 62 has a structure having a sharp blade, the heated portion can be stirred inside the pan case 12 while being crushed. If it carries out like this, the to-be-heated material 1 can be processed into a smooth liquid state only by putting a material. Thus, for example, by putting ingredients such as vegetables and milk in the cooking container 10, a smooth soup such as potage soup is cooked while sauces are automatically processed by adding ingredients such as meat and vegetables. be able to.

Thus, the microwave oven according to the present embodiment is compatible with various other types of cooking, and can improve the cooking performance of many menus. That is, with the resin plate 2 that can efficiently heat the cooking container 10 or guide it to various cooking positions, it is possible to perform cooking with less energy unevenness in a shorter time and with less energy, which is convenient.
