Description

  The present invention relates to a cooking device provided with a grill device, which is used in a kitchen of a general household, a commercial kitchen, or the like.

  Conventionally, the general configuration of the grill device of this type of heating cooker has been to arrange a cooking chamber in the grill device, store a saucer on which a grill is placed, and a heater called an electric heater called a sheathed heater. It is common to heat cooked food using the Joule heat of the hot wire, and particularly to heat both sides simultaneously.

  However, in such a structure, fats and oils and water | moisture content dripped from a cooking item to the heating body provided under the cooking chamber, smoke may generate | occur | produce abundantly and may adhere again to a cooking item, and there exists a possibility that a taste may be impaired. In rare cases, the oil and fat may ignite.

  Furthermore, the heating body arrange | positioned below becomes obstructive and lacks in the cleanability of the bottom face of a cooking cabinet. As a method for solving these problems, there is known a method in which a soaking plate is disposed above a heating body provided below, and a cooking heating plate is placed on the soaking plate and cooked.

Can be increased.

JP 2010-115473 A

  However, in the conventional configuration, unless the contact surface between the soaking plate and the cooking plate is increased, the heat conduction from the soaking plate to the cooking plate does not increase, and cooking heating is not performed. The plate shape is very limited. The cooking plate has a function to place the food directly and also serves as a saucer to receive the oil and fat and juice from the food. Therefore, there is a problem that it is difficult to widen the contact surface with the soaking plate.

  This invention solves the said conventional subject, and provides the heating cooker provided with the grill apparatus which has high cleaning performance and can be cooked efficiently.

  By adopting the above configuration, the upper heating body is arranged above the cooking chamber upper surface, and the lower heating body is arranged below the cooking cabinet bottom surface. You can cook food without placing it in the cooking cabinet. Furthermore, the amount of heat from the lower heating element is not only given to the grill pan through the bottom of the cooking chamber by heat conduction, but also the bottom of the cooking chamber is a light-transmitting high heat-resistant material, so that it is also applied to the grill pan by heat radiation. The amount of heat can be given. In addition, the sliding sound generated by the grill pan can be reduced by sliding the grill pan on the high heat-resistant material, and the amount of heat given to the grill pan from the lower heating body passes through the metal plate on the bottom of the cooking chamber. It is increased by conducting heat to a substantially horizontal plane on the lower surface of the grill pan. Further, the temperature of the grill pan can be detected more accurately than when the lower temperature detecting means is in contact with the high heat resistant material on the bottom surface of the cooking cabinet.

  The cooking device of the present invention is provided with a grill device for cooking both sides of the food at the same time, with an upper heating body disposed above the cooking chamber upper surface and a lower heating body disposed below the cooking chamber bottom surface.

According to a first aspect of the present invention, there is provided a main body having an opening upward, a top plate provided on the upper surface of the main body so as to cover the opening, a heating means for heating an object to be heated, and a lower part of the heating means A grill device located at the top, a cooking chamber for cooking the food disposed in the grill device, a grill door covering an opening for taking in and out the cooking material in the cooking chamber, and an upper surface of the cooking chamber An upper heating body for cooking the food to be disposed, a lower heating body disposed below the bottom surface of the cooking chamber, and housed in the cooking chamber, with a gap provided between the bottom surface of the cooking chamber and A grill plate in which a mountain portion to be placed and a valley portion for receiving oil etc. from the food product are integrally formed, and a lower temperature detecting means for detecting and controlling the temperature of the bottom surface of the cooking cabinet; And the bottom surface of the cooking chamber is made of a light transmissive high heat-resistant material and a part. The grill pan slides on the high heat-resistant material when being put in and out of the cooking chamber, and the lower temperature detecting means is on a substantially horizontal surface formed on the lower surface of the grill pan. It is configured to be in contact with or close to the metal plate at an opposing position.

  As a result, the upper heating body is arranged above the cooking chamber upper surface, and the lower heating body is arranged below the cooking cabinet bottom surface. When cleaning the inside, it is easy to put a hand in the cooking chamber for cleaning, and the cleaning performance can be made high. The amount of heat from the lower heating element is not only given to the grill pan through the bottom of the cooking cabinet by heat conduction, but also the bottom of the cooking cabinet is a light transmissive high heat-resistant material, so that it is also applied to the grill pan by heat radiation. It can give heat and can be cooked efficiently, and even if there are crests and troughs on the grill pan and there is a gap between the bottom of the cooking cabinet, heating by heat radiation is also added, especially The effect can be demonstrated. Furthermore, the shape restrictions of the grill pan can be reduced.

  And a lower temperature detecting means for detecting and controlling the temperature of the bottom surface of the cooking chamber, wherein the bottom surface of the cooking chamber is composed of a light transmissive high heat resistant material and partially composed of a metal plate, The pan slides on the high heat-resistant material when it is taken in and out of the cooking chamber, and the lower temperature detecting means contacts the metal plate at a position facing a substantially horizontal plane formed on the lower surface of the grill pan. Alternatively, when the grill pan slides on the high heat resistant material to reduce the sliding sound generated by the grill pan and the lower temperature detecting means comes into contact with the high heat resistant material on the bottom surface of the cooking cabinet by adopting a close configuration. Rather than detecting the temperature of the grill pan more accurately, temperature control cooking can be performed. In addition, by forming a substantially horizontal plane on the lower surface of the grill and making it be opposed to the metal plate on the bottom of the cooking cabinet, heat conduction from the bottom of the cooking cabinet to the grill pan can be improved, so the amount of heat given from the lower heating body to the grill pan is It is increased by conducting heat through a metal plate to a substantially horizontal plane on the lower surface of the grill pan.

  The second invention is particularly generated when the high heat-resistant material of the first invention is made of crystallized glass, so that it is rubbed with a grill pan formed of a metal having a good heat distribution due to the small frictional resistance of the glass. Because the sound is reduced and the high rigidity of the glass allows the grill plate to be placed on the bottom of the cooking chamber without sounding the entire grill device, the grill plate is placed in the cooking chamber throughout. It is possible to reduce the sliding noise when taking in and out of the machine.

  Embodiments and reference embodiments of the present invention will be described below with reference to the drawings. In addition, this invention is not limited by this embodiment or the reference form.

(Reference form 1)
FIG. 1 is an overall configuration diagram of a heating cooker according to a first reference embodiment of the present invention.

The main body 1 is bent in a box shape and has an opening on the upper side, and is arranged so as to cover the upper opening of the main body 1 by a top plate 3 on which the cooked cooking container 2 is placed. A heating means 5 for heating the cooked cooking container 2 is disposed below the top plate 3, and a substantially box-shaped grill device 6 is provided below the heating means 5, and the rear of the grill device 6. Or the exhaust pipe 7 provided above
Therefore, the oil smoke discharged when the food 14 is cooked in the cooking chamber 11 arranged in the grill device 6 is exhausted.

  Here, as a detailed view of the grill device 6, FIG. 2 shows a sectional view of the grill device of the heating cooker according to the first embodiment of the present invention. The grill device 6 is provided with a grill door 8 that covers an opening provided in front of the product for taking in and out the food 14 from the cooking chamber 11. Above the cooking chamber upper surface 16, an upper heating body 9 and cooking are provided. A lower heating body 10 is disposed below the bottom surface 17 of the cabinet.

  Above the bottom surface 17 of the cooking cabinet, a grill pan 18 in which a placing portion for the cooked food 14 and a saucer function portion for receiving oil etc. from the cooked food 14 are integrally formed is placed.

  At this time, it is preferable to use crystallized glass as the light-transmitting high heat resistant material, particularly a typical material for the cooking chamber bottom surface 17. In addition, the entire bottom surface 17 of the cooking cabinet may not be made of crystallized glass, but only necessary parts, for example, only parts where the grill pan 18 slides may be made of crystallized glass.

  With the above configuration, the upper heating body 9 is disposed above the cooking chamber upper surface 16, and the lower heating body 10 is disposed below the cooking cabinet bottom surface 17. Even if you put your hand in 11, there is nothing that will block your hand, so when cleaning the inside of the cooking cabinet 11, it is easy to put your hand in and clean the cooking chamber 11 it can.

  Moreover, when cooking the lower surface of the food 14, the bottom surface 17 of the cooking chamber is light-transmitting crystallized glass, so that the amount of heat from the lower heating body 10 is reduced by the bottom surface of the cooking chamber heated by the lower heating body 10. Not only can heat be transferred to the grill pan 18 via the heat transfer 17 via the heat transfer member 17, but also heat can be transferred from the lower heater 10 to the grill pan by heat radiation.

  That is, since the grill pan 18 is heated not only by heat conduction but also by heat radiation, the efficiency of cooking is improved. In addition, the grill pan 18 forms a grill pan crest 19 which is a crest for placing the cooked food, and forms a grill pan trough 20 which is a trough for receiving the oil and the like, and a function for placing the food 14. The grill pan 18 has irregularities and inclinations because it is integrated with a receiving tray function for receiving oil or the like from the cooked food 14.

  At this time, the grill pan valley portion 20 on the cooking chamber bottom surface 17 side does not contact the cooking chamber bottom surface 17. Therefore, heating by heat radiation is added, so that the shape restriction of the grill pan 18 can be reduced and cooking can be performed efficiently.

  Furthermore, the cooking chamber bottom surface 17 forms the cooking chamber 11, and is also a portion where the grill pan 18 slides and repeats friction. When the cooking chamber bottom surface 17 is formed only by a metal plate, it rubs against the grill pan 18 formed of a metal having a good heat distribution, resulting in friction between the metals, so that there is a high possibility that the sliding noise will increase. .

  In addition, since the product weight increases when the metal plate is thick, it is not preferable to increase the thickness, and a thin plate is often used. However, when the metal plate is thin, the rigidity is small, so when the grill pan 18 is slid. Since the vibration at the time of sliding is transmitted to the entire cooking chamber 11 and the entire grill device 6 vibrates and makes a sound, the sliding noise becomes larger.

  On the other hand, when the cooking chamber bottom surface 17 is formed of crystallized glass, it is possible to reduce the sound generated when rubbing against the grill pan 18 formed of metal having a good heat distribution due to the small frictional resistance of the glass.

  Further, since the high rigidity of the glass allows the grill pan to be placed on the entire grill device 6 without sounding when the grill pan is placed on the bottom surface 17, the grill pan 18 is placed throughout the cooking pan. The sliding sound at the time of taking in / out from inside 11 can be reduced.

(Reference form 2)
FIG. 3 shows a sectional view of the grill device of the cooking device according to the second embodiment of the present invention.

  The present embodiment is different in that the infrared sensor 21 is arranged below the bottom 17 of the cooking cabinet to detect the temperature of the grill pan 18. Others are the same as the reference form 1, and the description is omitted. Since the cooking chamber bottom surface 17 is formed of a light transmissive material such as crystallized glass, the temperature of the grill pan 18 is detected using a sensor using light such as the infrared sensor 21. It can be set as the structure to do.

  Since an optical sensor such as an infrared sensor can perform temperature control cooking with high accuracy, the grill device 6 capable of temperature control cooking with high accuracy can be obtained.

  Moreover, as shown in another block diagram of the grill device of the heating cooker in the second reference embodiment of the present invention in FIG. 4, a configuration in which the back surface temperature of the grill pan 19 on which the food 14 is placed is detected by the infrared sensor 21. Since it can detect and control the temperature of the position close to the food 14, temperature control cooking with higher accuracy can be made possible.

  If the infrared sensor 21 is used for the grill device 6 and only for the purpose of accurate temperature control cooking, only the infrared sensor 21 arrangement portion of the cooking cabinet bottom surface 17 may be formed of crystallized glass.

(Embodiment 1)
FIG. 5 shows a sectional view of the grill device of the cooking device according to the first embodiment of the present invention.

  In the present embodiment, a substantially horizontal surface 22 is formed on the lower surface of the grill pan 18, and the temperature is detected by bringing the lower temperature detection means 23 into contact with or in proximity to the back surface of the cooking chamber bottom surface 17 at a position opposite to the approximately horizontal surface 22. Is different. Others are the same as the reference form 1, and the description is omitted.

  With the above configuration, the temperature detection capability and the temperature control capability are inferior to those using a light sensor, but the substantially horizontal surface 22 is formed on the lower surface of the grill pan 18 while detecting the temperature of the grill pan 18. Since the contact surface with the cooking chamber bottom surface 17 increases, the heat conduction from the cooking cabinet bottom surface 17 to the grill pan 18 can be improved.

  At this time, as shown in FIG. 5, the cooking chamber bottom surface 17 with which the lower temperature detection means 23 comes into contact may not be partially crystallized glass, and may be a metal plate 24 having good heat conductivity. By using the metal plate 24, the amount of heat from the lower heating body 10 transmitted through the metal plate 24 to the substantially horizontal surface 22 on the lower surface of the grill pan 18 by heat conduction is increased.

  Further, since much heat is transmitted from the grill pan 18 by heat conduction, the temperature can be detected more accurately than when the bottom surface 17 of the cooking chamber with which the lower temperature detecting means 23 contacts is crystallized glass.

(Reference form 3)
FIG. 6 is a sectional view of the grill device of the cooking device according to the third embodiment of the present invention.

  In the present embodiment, a part of the grill pan rear wall surface 25 and a part of the cooking cabinet rear surface 26 are brought close to each other, and the rear temperature detection means 27 is brought into contact with or close to the outer surface of the cooking cabinet rear surface 26 to detect the temperature. It is different in point. Others are the same as the reference form 2, and the description is omitted. Although the temperature detection capability and temperature control capability are inferior to using the sensor by light by setting it as the said structure, the temperature of the grill pan rear wall surface 25 can be detected and temperature control cooking can be performed. Further, by providing the rear temperature detection means 27 at the rear of the grill device 6, it becomes possible to widen the height direction in the cooking chamber 11 compared to providing the temperature detection means below the bottom surface 17 of the cooking cabinet, and the thickness is increased. A certain food 14 can be cooked.

  In addition to the above configuration, the temperature of the grill pan 18 may be detected using both the lower temperature detection unit 23 and the rear temperature detection unit 27 in combination with the first embodiment.

(Reference form 4)
FIG. 7 is a sectional view of the grill device of the cooking device according to the fourth embodiment of the present invention.

  The present embodiment is different from the first embodiment in that a reflector 28 for reflecting heat radiation from the lower heater 10 downward is formed below the lower heater 10 in Reference Embodiment 1. Others are the same as the reference form 1, and the description is omitted.

  By adopting the above-described configuration, the heat radiation directed downward from the lower heating body 10 can be reflected by the reflecting plate 28 and directed upward with the grill pan 18, so that the amount of heat generated by the radiation from the lower heating body 10 can be reduced. In addition, the heating efficiency can be improved. At this time, the reflection plate 28 may be provided not only below the lower heating body 10 but also above the upper heating body 9.

  As described above, the heating cooker according to the present invention can be applied to all types provided with a grill device, and is intended to provide cleanliness inside the grill device, or cooking that requires accurate temperature control cooking. It is effective for the vessel.
