Description

  The present invention relates to a cooking device for cooking food to be heated such as food.

  In the field of such a cooking device, equipment such as an oven microwave oven that can easily cook an object to be heated, such as food, using radio waves, infrared rays, hot air, etc. as a heating source is generally widespread (for example, Patent Document 1).

In the heating cooker described in Patent Document 1, as shown in FIG. 5, a fan casing 2 is provided on the back of the heating chamber 1, a centrifugal fan 3 for air circulation is disposed in the fan casing 2, and the heating chamber 1. An upper heater 6 and a lower heater 7 are provided at the rear of the ceiling and the rear of the bottom so as to receive the air discharged from the upper discharge port 4 and the lower discharge port 5, and the heat from the upper heater 6 and the lower heater 7 is provided. Are provided in the vicinity of the upper heater 6 and the lower heater 7, respectively, so that the upper reflecting plate 9 and the lower reflecting plate 10 are reflected toward the heated object 8 on the top plate installed in the approximate center of the heating chamber 1. 6. The lower heater 7 is used for both hot air generation and grill cooking.
JP-A-5-172344

  However, in the configuration of the conventional cooking device shown in FIG. 5, the heat from the upper heater 6 and the lower heater 7, that is, infrared rays, is reflected and scattered by the upper reflector 9 and the lower reflector 10, respectively, and the heated object such as food. It is well known from Stefan-Boltzmann's law that the infrared energy from the upper heater 6 and the lower heater 7 changes its thermal energy depending on the distance from the object 8 to be heated. The thermal energy is inversely proportional to the square of the distance between the upper heater 6 and the lower heater 7 and the object 8 to be heated. Accordingly, the heat energy applied to the object to be heated 8 due to the effects of the upper reflecting plate 9 and the lower reflecting plate 10 naturally increases and decreases between the back surface side and the door side of the object to be heated 8, and this difference is There was a tendency that the difference in the baked color before and after 8 and the variation in the internal temperature increased.

  The air discharged from the centrifugal fan 3 into the heating chamber 1 is hot air that has been heated to some extent by circulation from the heating chamber 1. Therefore, the wind discharged from the upper discharge port 4 and the lower discharge port 5 into the heating chamber 1 is discharged while having a tendency of an upward air flow. Therefore, the hot air circulating on the lower surface side of the object to be heated 8 has a lower temperature than the hot air circulating on the upper surface of the object to be heated 8, and there is a tendency that a difference occurs in the color of the upper and lower surfaces of the object to be heated 8. .

  Thus, due to the configuration, a temperature difference inevitably occurs around the object to be heated 8, it is difficult to realize a uniform heating state, and the object to be heated 8 is placed behind the mounting shelf, Alternatively, there is a measure for ensuring the uniformity of the temperature distribution, such as increasing the heat generation of the upper and lower heaters 6 and 7 and forcibly equalizing the temperature distribution in the heating chamber 1 with a large capacity fan or the like. However, it became indispensable, and as a result, there was a problem that the casing of the heating cooker was heated.

  The present invention solves the above-described conventional problems, and regardless of the state of the object to be heated, the entire object to be heated is colored uniformly and at the same time the internal temperature of the object to be heated is made uniform. An object of the present invention is to provide a cooking device that realizes a good finished state by raising the temperature, further prevents the casing of the cooking device from being heated at high temperature, and is rich in energy saving.

  In order to solve the above-described conventional problems, a heating cooker according to the present invention includes a heating chamber having an open / close door and containing an object to be heated, and a microwave generated by a magnetron and propagated through a waveguide into the heating chamber. A power supply port provided on the wall surface of the heating chamber to be irradiated, an upper heat source and a lower heat source provided respectively on the top and bottom surfaces of the heating chamber, and a placement for placing the object to be heated provided in the heating chamber And a rotating means for rotating the mounting section, and hot air supply means for supplying hot air into the heating chamber, the power supply port is provided at a position near the opening / closing door, and the upper heat source, A lower heat source and the hot air supply means are provided at a position farther from the open / close door.

  In this heating cooker, for example, by providing a power feeding port for irradiating microwaves at a position near the opening and closing door, and providing an upper heat source and a lower heat source at a position on the far side of the heating chamber far from the opening and closing door, Even in the case of combined simultaneous heating by the microwave, upper heat source, and lower heat source, the microwave interferes with the upper heat source and the lower heat source to generate sparks, which may cause the upper heat source and the lower heat source to rise in partial temperature. Can be avoided.

  When the object to be heated is located below the power supply opening on the door side due to the rotation of the mounting portion, microwave heating becomes dominant, and the object to be heated is located on the back side of the heating chamber. At times, radiant heating by the upper heat source and the lower heat source becomes dominant, and these are repeated alternately.

Furthermore, by supplying hot air into the heating chamber by the hot air supply means, it is possible to heat all parts of the object to be heated that could not be heated by radiant heating using the upper heat source and the lower heat source.
In this way, it is possible to realize an optimal cooking state for various objects to be heated.

  Moreover, from the arrangement of the power supply port, the upper heat source, and the lower heat source, at least the opening / closing door can be prevented from being heated at high temperature, the abnormal overheating of the casing of the heating cooker can be prevented, and the user can perform a comfortable operation.

  As described above, it is possible to uniformly raise the internal temperature of the heated object regardless of where the heated object is placed on the placement unit, and to obtain a good baked color on both the upper and lower surfaces, and It is possible to provide a heating cooker rich in energy saving that can prevent the casing from becoming hot.

  According to the heating cooker of the present invention, the microwave interferes with the upper heat source and the lower heat source from the proper arrangement of the power supply port, the upper heat source, and the lower heat source, and causes a situation such as a spark or partial abnormal overheating. Prevents the heated object from being placed on any part of the mounting part, the internal temperature of the heated object can be raised uniformly, and a good brilliant color can be applied to both the upper and lower surfaces. It is possible to provide an energy-saving heating cooker that prevents abnormal overheating and enables a comfortable operation by the user.

  A first aspect of the present invention is a heating chamber having an opening / closing door for accommodating an object to be heated, and a power supply opening provided on a wall surface of the heating chamber for irradiating the heating chamber with microwaves generated by a magnetron and propagating through a waveguide An upper heat source and a lower heat source respectively provided on the top and bottom surfaces of the heating chamber, a placement portion provided in the heating chamber for placing the object to be heated, and a rotating means for rotating the placement portion And hot air supply means for supplying hot air into the heating chamber, the power supply port is provided at a position near the open / close door, and the upper heat source, the lower heat source, and the hot air supply means are provided in the open / close door. It is provided at a position on the far side.

As a result, a power supply port for irradiating microwaves is provided at a position near the opening / closing door, and an upper heat source and a lower heat source are provided at positions far from the opening / closing door, so that the microwave, upper heat source, and lower heat source are used. Even in the case of combined simultaneous heating, it is possible to prevent the microwave from interfering with the upper heat source and the lower heat source to generate a spark, and thus the partial temperature rise of the upper heat source and the lower heat source can be avoided.

  When the object to be heated is located below the power supply opening on the door side due to the rotation of the mounting portion, microwave heating becomes dominant, and the object to be heated is located on the back side of the heating chamber. At times, radiant heating by the upper heat source and the lower heat source becomes dominant, and these are repeated alternately.

  Furthermore, by supplying hot air into the heating chamber by the hot air supply means, it is possible to heat all parts of the object to be heated that could not be heated by radiant heating using the upper heat source and the lower heat source.

  Moreover, from the arrangement of the power supply port, the upper heat source, and the lower heat source, at least the opening / closing door can be prevented from being heated at high temperature, the abnormal overheating of the casing of the heating cooker can be prevented, and the user can perform a comfortable operation.

  Thus, no matter where the object to be heated is placed, the internal temperature of the object to be heated can be uniformly raised, and a good brilliant color can be applied to the upper and lower surfaces, and the housing It is possible to provide a cooking device that can prevent the temperature from becoming high and has high energy saving performance.

  According to a second aspect of the present invention, there is provided a heating chamber having an opening / closing door for accommodating an object to be heated, and a power supply port provided on a wall surface of the heating chamber for irradiating the heating chamber with a microwave generated by a magnetron and propagating through a waveguide An upper heat source and a lower heat source provided on the top and bottom surfaces of the heating chamber, a lower heat source provided outside the heating chamber, and a placement for placing the object to be heated provided inside the heating chamber, respectively. A rotating means for rotating the mounting portion, and hot air supply means for supplying hot air heated by the lower heat source into the heating chamber, and the power supply port is provided at a position near the opening / closing door, In addition, the upper heat source, the lower heat source, and the hot air supply means are provided at positions farther from the opening / closing door.

  As a result, the lower heat source is provided outside the heating chamber, and the lower heat source is used as the heat source of the hot air supply means, so that the object to be heated is placed on any part of the placement part, as in the first invention. To provide an energy-saving cooking device that can uniformly raise the internal temperature of the object to be heated, put a good baking color on the top and bottom surfaces, and prevent the casing from becoming hot. Can do.

  Furthermore, since there is no lower heat source directly under the object to be heated, debris and oil droplets of the object to be heated generated during cooking do not come into contact with the lower heat source, and a situation such as smoke generation can be prevented.

  In a third aspect of the invention, particularly in the first or second aspect of the invention, the upper heat source and the lower heat source are constituted by infrared heaters that irradiate infrared rays toward the mounting portion.

  Thus, the upper and lower surfaces of the object to be heated are elements of finish in which the uniformity of the baked color is important, so that the upper and the lower heat sources can be heated by the infrared heater that is easy to get the baked color.

  In a fourth aspect of the invention, in particular, in the third aspect of the invention, the infrared heater uses a red heat type heater in which a heating wire is embedded in a quartz tube or a ceramic tube.

  As a result, it is possible to ensure a quick rise in red heat as compared with a metal sheathed heater or the like, speed up the surface temperature of the object to be heated, and shorten the cooking time.

In a fifth aspect of the invention, particularly in the first or second aspect of the invention, the hot air supply means is provided with a circulation hole in the vicinity of the upper heat source, a hot air outlet hole is provided in the heating chamber rear wall surface, and sucks air in the vicinity of the upper heat source. Hot air is discharged.

  Thereby, since the high-temperature air that is in contact with the upper heat source and exchanged heat can be brought into contact with the object to be heated as hot air, basically, it is not necessary to add a separate heat source, and the configuration can be simplified. .

  In a sixth aspect of the invention, particularly in the first or second aspect of the invention, the hot air supply means supplies the hot air from the rear wall surface of the heating chamber facing the open / close door obliquely downward from the upper side and the lower side of the mounting portion. Is.

  Thereby, since the tendency of the rising airflow of hot air can be canceled in advance, the hot air can be brought into contact over a wide range of the object to be heated.

  In addition, for cooking menus such as pizza heating that require a lower baking color on the object to be heated compared to the upper surface, the lower heat source is turned off and the hot air flows diagonally downward from the lower side of the mounting section. It is possible to give a light baked color to the lower surface of the object to be heated simply by supplying.

  Therefore, it is possible to ensure energy saving while supporting various cooking menus.

  In a seventh aspect of the invention, in particular, in any one of the first to sixth aspects of the invention, the rotating means of the mounting portion changes the rotation speed at least between the cooking start period and the cooking completion period of the article to be heated. It is.

  This makes it possible to ensure an optimal rotation state depending on the type and amount of the object to be heated, whether or not there is combined heating with microwaves, etc., achieving a uniform temperature rise of the object to be heated, and uniform baking. Can wear color.

  In the eighth invention, particularly the seventh invention, the rotation speed of the rotating means of the mounting portion is higher in the vicinity of the cooking completion period than in the cooking start period of the article to be heated.

  As a result, during the cooking start period when the temperature of the whole object to be heated is low, the rotation speed of the mounting unit is reduced, the contact time between the upper heat source and the lower heat source and the object to be heated is increased, and the temperature of the object to be heated is increased. Faster, a somewhat rough baked color can be formed.

  After that, by increasing the rotation speed within a range in which a stable placement state of the object to be heated can be ensured, the color of the entire object to be heated can be made uniform. Such adjustment of the rotational speed can be easily changed in stages by the type, amount, and combined heating with the microwave, and accordingly, according to various heating modes. A uniform heating state can be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 is a side sectional view of a heating cooker according to Embodiment 1 of the present invention, FIG. 2 is a conceptual diagram of a heating state in the case of baking heating by the heating cooker according to the embodiment, and FIG. It is a conceptual diagram of the heating state in the case of the combined simultaneous heating of microwave and baking by a heating cooker.

  The configuration, operation, and action of the heating cooker according to Embodiment 1 of the present invention will be described using the above drawings.

  In FIG. 1, a heating chamber 11 having a front opening is configured in a housing 10, and an opening / closing door 12 includes a front side of the outer shell 10 with a lower side as a fulcrum on the opening side of the heating chamber 11. It is installed so that it can be opened downward.

  On the lower side of the center of the heating chamber 11, a slat-net-shaped mounting portion 13 is provided. The mounting portion 13 is directly connected to a motor 16 (rotating means 15) installed between the bottom of the heating chamber 11 and the outer shell 10 via a rotating shaft 14 that penetrates the bottom of the heating chamber 11. .

  A red heat type upper infrared heater 20 (upper heat source 19) in which a coiled heating wire is embedded in a quartz tube or a ceramic tube in a recess 18 provided on the ceiling surface in the heating chamber 11 and in the vicinity of the rear wall surface 17 side. In the recess 21 provided near the rear wall 17 on the bottom surface in the heating chamber 11, a red heat type lower infrared heater 23 in which a coiled heating wire is similarly embedded in a quartz tube or a ceramic tube. Both (lower heat source 22) are installed substantially parallel to the rear wall surface 17 of the heating chamber 11.

  The upper infrared heater 20 changes its surface temperature in a range of about 500 to 800 ° C., and is set between 500 and 1000 W as a variable range of W (watt) number. On the other hand, since the lower infrared heater 23 is close to the mounting portion 13, the surface temperature thereof is set to be lower than that of the upper infrared heater 19 and is changed in the range of 400 to 700 ° C. The variable range of the (watt) number is set between 400 and 700 W.

  Further, a hot air passage 24 is formed in the rear wall surface 17, and the hot air passage 24 includes a plurality of obliquely downward upper hot air ejection holes 25 provided on the upper side of the placement portion 13 on the rear wall surface 17, and the placement portion 13. The plurality of lower hot air jet holes 26 provided obliquely downward and the plurality of circulation holes 27 provided on the rear side of the recess 18 are communicated with each other. And in the hot air path 24, the circulation fan 28 comprised by the cross flow fan is installed in the vicinity of the upper hot air ejection hole 25 and the lower hot air ejection hole 26. FIG. As described above, the hot air supply unit 29 is configured by the hot air passage 24, the upper hot air ejection hole 25, the lower hot air ejection hole 26, the circulation hole 27, and the circulation fan 28.

  On the other hand, on the open / close door 12 side above the heating chamber 11, a waveguide 31 directly connected to a magnetron 30 as a high-frequency generator is connected to the heating chamber via a power supply port 32 provided on the ceiling surface in the heating chamber 11. 11, microwaves generated in the magnetron 30 propagate through the waveguide 31 and are irradiated into the heating chamber 11.

  The effect | action in the heating cooker comprised as mentioned above is demonstrated.

  In FIG. 2, when a heated object A such as food is placed on the slat-net-shaped placing part 13 in the heating chamber 11 and the open / close door 12 is closed, the cooking of the heated object A is performed by a predetermined operation. Be started.

  For example, when the object A to be heated is a toast or the like, normally, microwave heating is not used but cooking is performed only by baking and heating, and the upper infrared heater 20 (upper heat source 19) and the lower infrared heater are used. 23 (lower heat source 22) and hot air supply means 29 are used for cooking. In this case, when the upper infrared heater 20 and the lower infrared heater 23 are energized, the surface temperatures of the upper infrared heater 20 and the lower infrared heater 23 reach about 700 ° C. and about 600 ° C. relatively fast, respectively, and are heated. Of the upper and lower surfaces of the object A, the infrared rays 33 and 34 are strongly heated from the center of the mounting portion 13 to the rear wall surface 17 side.

At the same time, when the circulation fan 28 is operated, the air in the heating chamber 11 is sucked into the hot air passage 24 through the circulation hole 27, and the heated object A is discharged from the upper hot air blowing hole 25 and the lower hot air blowing hole 26. Hot air is spouted toward At this time, the air sucked from the circulation hole 27 contacts the surface of the upper infrared heater 20 and proceeds to the hot air passage 24 while exchanging heat, so that the temperature of the upper infrared heater 20 and the inside of the heating chamber 11 are increased. As the temperature rises, the hot air 35 is gradually heated to the heated object A from the upper hot air blowing hole 25 and the lower hot air blowing hole 26 and is blown below the placement unit 13 as the hot air 35 gradually heated. The

  In this manner, the temperature of the hot air 35 finally reaches around 280 to 300 ° C. Moreover, since the upper hot-air ejection hole 25 and the lower hot-air ejection hole 26 are preliminarily configured to be ejected obliquely downward, the amount of hot air that passes through the hot air 35 without being in contact with the object A to be heated. Is reduced as much as possible.

  Accordingly, the upper and lower surfaces of the object to be heated A are efficiently and quickly heated from the center to the rear wall surface 17 by the infrared rays 33, infrared rays 34, and hot air 35. The temperature rise of the whole 10 can also be suppressed, and the part that the user usually touches can be maintained at a safe temperature.

  On the other hand, the placement unit 13 is rotated at a constant rotational speed simultaneously with the start of heating of the article A to be heated.

  For example, the heating time of the object A to be heated by the infrared ray 33, the infrared ray 34, and the hot air 35 is secured long by rotating at a relatively slow speed such as 6 to 9 rotations per minute for a predetermined time from the cooking start period. Then, the temperature rise is accelerated, and a rough baked color is formed on the whole. After that, by raising the heated object A to a relatively fast rotational speed of 12 to 18 rotations within a range in which a stable placement state of the heated object A can be secured, for example, the color of the entire heated object A is increased. It can be made uniform. In this way, since the baked color can be quickly applied, it is possible to minimize the decrease in the weight of the article A to be heated due to heating and realize a finish with a good texture.

  On the other hand, as shown in FIG. 3, when the object to be heated B requires combined simultaneous heating in which thawing warming heating and baking heating are simultaneously performed, such as frozen pizza, In the heating and thawing heating by the microwave 36, and on the rear wall 17 side of the heating chamber 11, different cooking states are formed before and after the mounting portion 13 such as the infrared heating 33, the infrared heating 34, and the heating heating by the hot air 35. . By doing so, the whole object to be heated B is subjected to thawing warming heating and baking heating alternately by the motor 16 (rotating means 15) of the mounting portion 13. Similarly, the placement unit 13 changes the rotation speed between the cooking start period and the cooking completion period to adjust the finished state of the article to be heated B, and finally form a uniform temperature rising state and a baked color. be able to.

  At this time, the power supply port 32 is provided near the opening / closing door 12, and the upper heat source 19, the lower heat source 22, and the hot air supply means 29 are provided on the rear wall 17 side of the heating chamber 11, which is far from the opening / closing door 12. Therefore, even in the case of the combined simultaneous heating as described above, the microwave 36 interferes with the upper infrared heater 20 (upper heat source 19) and the lower infrared heater 23 (lower heat source 22) to generate a spark, or a partial temperature. It is possible to achieve a quick cooking state that is optimal for various objects to be heated B and avoids rising.

  As described above, it is possible to respond to various types of cooking of heated objects, and can quickly cook the heated object at the same time, providing energy-saving and uniform cooking, and providing a safe cooking device. can do.

(Embodiment 2)
FIG. 4 is a side cross-sectional view of a heating cooker and a conceptual diagram of a heating state in the case of baking and heating in Embodiment 2 of the present invention.

  The configuration, operation, and action of the heating cooker according to Embodiment 1 of the present invention will be described using the above drawings.

  In FIG. 4, the difference from the first embodiment is that a lower infrared heater 41 (lower heat source 40) is provided outside the heating chamber 43, and in the hot air passage 24, the circulation fan 28, the upper hot air ejection hole 25, and the lower hot air ejection. A lower infrared heater 41 is provided as a heat source for the hot air supply means 42 between the holes 26 and the bottom surface of the heating chamber 43 is substantially planarized accordingly.

  In addition, the same code | symbol is attached | subjected to the same structure as 1st Embodiment, and detailed description is abbreviate | omitted.

  In FIG. 4, when a heated object A such as toast is placed on the placing part 13, the upper and lower surfaces of the heated object A are hot air 44 from the infrared ray 33, the upper hot air blowing hole 25 and the lower hot air blowing hole 26. Thus, it is cooked. At this time, since the lower infrared heater 41 (lower heat source 40) is provided on the downstream side of the circulation fan 28, the temperature of the hot air 44 rises at a high temperature of 280 to 300 ° C. from the initial stage, and is on the upper and lower surfaces of the object A to be heated. A baked color can be formed quickly. Therefore, as in the first embodiment, it is possible to minimize the decrease in the weight of the article A to be heated and realize a finish with a good texture.

  Furthermore, there is no lower heat source 40 directly under the object to be heated, and the bottom surface of the heating chamber 43 is substantially planarized so that debris and oil droplets of the object to be heated generated during cooking do not contact the lower heat source 40. In addition to preventing smoke and other situations, these debris and oil droplets can be easily removed.

  As described above, since the top and bottom of the object to be heated can be simultaneously heated in a short time, similarly, it is possible to provide a cooking device that is highly energy-saving, capable of uniform and high-speed cooking, and is safe and easy to maintain. be able to.

  As described above, the heating cooker of the present invention is capable of uniform and simultaneous heating while suppressing interference between a microwave and a heat source such as a heater, and thus is not limited to a cooker such as a microwave oven. It can be applied to various heating applications.
