Japanese Patent No. 3596440 (FIG. 1) JP 2007-327676 A (FIG. 1)

  However, in the cooking device having heating means for generating infrared rays at the upper and lower parts of the cooking chamber, the food placed on the grill is located on the lower heating means, When cooking food that leaches out and cooking food that generates food residue when placed, it falls on the lower heating means in a high temperature state and burns, so smoke and burnt odors Occurs.

  In addition, in a cooking device provided with heating means for generating infrared rays and microwave heating means, light from the backside heating means incident on the cooking chamber diffuses as it travels through the cooking chamber. The ratio of the amount of light that is reflected at the bottom and reaches the lower side of the food is reduced. For this reason, the lower side of the food item cannot be efficiently heated, and a long time is required for sufficient cooking.

  In addition, when the upper heating means and the rear heating means are energized at the same time, the amount of heat applied to the lower side of the food becomes smaller than the amount of heat applied to the upper side of the food, and the food is heated unevenly up and down. The cooking finish is poor.

  The technical problem of the present invention is to suppress the generation of smoke and a burning odor even when cooking a food in which oil is leached by heating or a food in which food waste is generated when placed, It is to make it possible to uniformly heat the cooked food by applying heat efficiently to the lower side.

  The cooking device according to the present invention has the following configuration. That is, a cooking chamber for storing the cooked food, a mounting table that is detachably provided in the cooking chamber, and on which the cooking product is placed, an upper heating means disposed above the placing table in the cooking chamber, and a mounting table for the cooking chamber An infrared heating means that is disposed outside the area and generates infrared rays; and a reflecting portion that is formed around the infrared heating means and reflects the infrared rays generated by the infrared heating means toward the mounting table area side. In a heating cooker that heats cooked food placed on a table from both the top and bottom directions using infrared rays generated by the upper heating means and infrared heating means, a detachable reflecting member is provided in the cooking chamber. The member reflects the infrared ray directly irradiated from the infrared heating means during cooking and the infrared ray reflected by the reflecting portion toward the lower surface of the mounting table.

  According to the heating cooker of the present invention, since the infrared heating means is arranged outside the mounting table area of the cooking chamber, even if oil or food waste falls from the cooked food, these fall on the infrared heating means. There is nothing, and it is possible to suppress the generation of smoke and a burning odor during cooking, and the cleanability after cooking is improved. Furthermore, a detachable reflecting member is provided in the cooking chamber so that the infrared ray directly irradiated from the infrared heating means and the infrared ray reflected by the reflecting portion are reflected toward the lower surface of the mounting table. Heat can be efficiently applied to the underside of the food. For this reason, heating up and down uniformly with respect to a foodstuff is attained, cooking time is short, and the cooking device with the finishing of cooking can be obtained.

Embodiment 1 FIG.
The present invention will be described below with reference to illustrated embodiments.
1 is a cross-sectional view in side view showing a state in which a mounting table and a lower reflecting member are installed in a cooking chamber of a heating cooker according to Embodiment 1 of the present invention.

  As shown in FIG. 1, the heating cooker according to the first embodiment includes a cooking chamber 2 inside a main body 1, and a door 4 having a window 3 is provided on the front side of the main body 1. In addition, in the cooking chamber 2, a mounting table 6 constituted by a metal grid for mounting the food 5 is detachably installed and supported by guide rails (not shown) provided on the side of the cooking chamber 2. It has become so.

  Above the mounting table 6, an upper heating means for generating infrared rays, that is, an upper glass tube heater 8 lies horizontally. In addition, a lower glass tube heater 9 as an infrared heating means is horizontally placed on the outside of the mounting table area of the cooking chamber 2, that is, on the back surface of the cooking chamber 2 behind the mounting table 6 below the mounting table 6. The cooking chamber 2 side is opened, that is, the circumference is surrounded by the reflection portion 10 having an infrared incident portion on the front side of the cooking chamber 2, and the infrared rays generated by the lower glass tube heater 9 are placed on the mounting table area by the reflection portion 10. Reflected toward the side.

  A lower reflection member 11 is provided below the mounting table 6, and the infrared light generated by the lower glass tube heater 9 and the infrared light reflected by the reflection unit 10 are reflected toward the lower surface of the mounting table 6 by the lower reflection member 11. Thus, the lower side of the food 5 is heated.

  The bottom surface of the lower reflecting member 11 has a plurality of inclined surfaces. From the side close to the lower glass tube heater 9 to the front end portion, a horizontal surface 12 facing the mounting table 6 substantially in parallel, a first upwardly inclined angle is small. One inclined surface 13 and a second inclined surface 14 having a large upward inclination angle are formed.

  Further, as shown in the exploded perspective view of the mounting table and the lower reflective member in FIG. 2, the lower reflective member 11 is formed in a box shape having a bottom surface and a side surface, and the side surface and the upper surface on the lower glass tube heater 9 side. The side is open, and a handle 15 is provided at the tip, and flanges 16 are provided on both sides.

  FIG. 3 is a perspective view showing a state (assembled body) in which the lower reflecting member 11 is attached to the mounting table 6, and the flange 16 is detachably supported by the support bodies 17 provided on the left and right sides of the mounting table 6. Thus, it is slidably placed on a guide rail (not shown) provided integrally on the side surface of the cooking chamber 2.

  As shown in FIG. 1, the lower reflecting member 11 is installed in the cooking chamber 2 so as to cover the opening of the reflecting portion 10, and infrared rays generated by the lower glass tube heater 9 are on the bottom surface of the lower reflecting member 11. By the horizontal surface 12, the first inclined surface 13, and the second inclined surface 14, it has a function of reflecting upward and collecting it under the food.

  The second inclined surface 14 on the distal end side of the lower reflecting member 11 is closer to the mounting table 6 than the first inclined surface 13 and has a larger inclination angle. Thereby, infrared rays can be efficiently directed upward even at a position far from the lower glass tube heater 9 and where the amount of heat of infrared rays is small, and the food 5 can be heated uniformly.

  Moreover, since the lower reflective member 11 is configured in a box shape having side surfaces, the infrared light is reflected upward without leaking in the side surface direction. For this reason, the food 5 can be heated more quickly.

  The food 5 is heated from above and below by infrared rays emitted from the upper glass tube heater 8 and the lower glass tube heater 9. For this reason, heating (cooking) with respect to the cooked product 5 is possible.

  The cooking device of the first embodiment has a food residue generated when the food 5 is taken in and out of the cooking chamber 2 or oil or juice generated by heating the food 5 falls down. Does not fall on the lower glass tube heater 9.

  Since the lower reflecting member 11 is made of a metal material such as iron, stainless steel, and aluminum having high infrared reflection efficiency, absorption of infrared heat can be reduced, so that the temperature is lower than the surface temperature of the lower glass tube heater 9. It becomes. Thereby, even if food waste, oil, juice, etc. falling from the cooked food 5 fall on the lower reflecting member 11, it becomes difficult to emit smoke, and the inside of the cooking chamber 2 can be reduced and discharged outside the cooking device. Can reduce the amount of smoke produced.

  Moreover, since the oil and juice of the cooked food 5 fall on the lower reflective member 11, the bottom surface of the main body 1 of the cooking chamber 2 can be prevented from being soiled. Furthermore, since the lower reflective member 11 can be removed from the cooking chamber 2, it can be easily cleaned.

  In addition, it is preferable to perform a hydrophilic treatment on the surface of the lower reflective member 11. As a result, even when oil or juice dropped from the cooked product 5 is burnt, water can enter between the hydrophilic treatment surface and the adhering portion by immersing in water, so that the bond can be cut and easily washed off. Can do.

  Even when the lower reflecting member 11 is made of a heat-resistant material such as ceramic that does not have high infrared reflection efficiency, the same effect can be obtained by laying a sheet having high infrared reflection efficiency such as aluminum foil on the bottom surface. it can. Thereby, cleaning can be further facilitated.

  In the first embodiment, the bottom surface of the lower reflecting member 11 is configured with three surfaces (horizontal surface 12, first inclined surface 13, and second inclined surface 14), but the present invention is not limited to this. The distance to the mounting table 6 may be shortened as the distance from the lower glass tube heater 9 increases. For example, it may be composed of one inclined surface, four or more inclined surfaces, or a continuous curved surface. In the same manner as described above, infrared rays can be uniformly applied to the food 5.

  Further, the upper glass tube heater 8 and the lower glass tube heater 9 of the first embodiment include a quartz tube heater having a resistance heating wire inside the quartz tube, and a halogen heater in which an inert gas is sealed around the filament. However, it is possible to use other heaters that generate infrared rays, such as carbon heaters and sheathed heaters.

  Further, the horizontal surface 12 of the first embodiment only needs to be substantially horizontal with respect to the mounting table 6, and even if it has a slight inclination on the tip side of the lower reflecting member 11, an infrared reflection effect is obtained similarly. be able to. By comprising in this way, it can prevent that the oil and juice which generate | occur | produced from the foodstuff 5 spill over to the bottom face of the main body 1 of the cooking chamber 2. FIG.

  FIG. 4 is a cross-sectional view in a side view showing a state in which the mounting table 6 and the lower reflecting member 11 are removed from the cooking chamber 2 of the heating cooker according to the first embodiment, and pulls the handle 7 to bring the door 4 to the front. The state which removed the lower reflection member 11 united with the mounting base 6 from the cooking chamber 2 in the open state is shown.

  Since the lower reflecting member 11 can be removed from the mounting table 6, food waste, oil and soup of the cooked food 5 dropped on the bottom surface of the lower reflecting member 11 can be easily discarded and the inside of the cooking chamber 2 can be easily disposed. Can be cleaned.

  In the first embodiment, one lower glass tube heater 9 is arranged on the back side of the cooking chamber 2. However, the present invention is not limited to this. Even when the bottom surface of the side reflecting member 11 is configured to incline upward toward the opposite side of the lower glass tube heater, the infrared rays can be uniformly applied to the food 5 as described above.

  In addition, one lower glass tube heater 9 is arranged on each side of the cooking chamber 2 and two lower reflecting members 11 are installed symmetrically corresponding to the lower glass tube heaters 9 on both sides. Even if the bottom surface of the reflecting member 11 is inclined upward toward the center of the cooking chamber 2, the infrared rays can be uniformly applied to the cooked food 5 as described above.

  Moreover, when the mounting area | region of the foodstuff 5 is narrow with respect to the mounting base 6, the empty space where the foodstuff 5 is not mounted on the mounting base 6 generate | occur | produces, and infrared rays are not irradiated to the lower side of the cooking base 5 It leaks upward and is diffused into the cooking chamber 2, so that the heating efficiency is deteriorated. In this case, by arranging the upper reflecting member in the empty space, the infrared rays that are about to leak from the food 5 and leak upward are reflected by the upper reflecting member toward the lower lower reflecting member 11 and guided to the food 5. The lower side of the food 5 can be efficiently heated. Details of the upper reflecting member will be described later.

  The turbo fan 34 has a function of rotating and sucking the air in the cooking chamber 2 into the circulation chamber 35 through the intake port 37 and sending it to the rear glass tube heater 31 of the reflecting portion 32.

  The air heated by the back glass tube heater 31 in the reflection part 32 is sent into the cooking chamber 2 through the back opening 33.

  As described above, when the turbo fan 34 is driven without installing the lower reflecting member 11 in the cooking chamber 2, convection of hot air can be generated inside the cooking chamber 2, and the temperature in the cooking chamber 2 rises. Can be made faster.

  Further, when a cooking plate 43 made of ceramic or iron plate is supported on the guide rail 42 on the side surface of the cooking chamber 2 and installed at a height reaching the intake port 37, the air circulating in the space above the cooking plate 43 and cooking Since it divides into air circulating over the space above and below the plate 43, the temperature of the space above the small circulation loop becomes high. For this reason, the cooking time on the cooking plate 43 can be shortened.

  As shown in FIGS. 13 and 14, the back glass tube heater 31 is disposed at an upper position in the back surface heating chamber 30, and the mounting table 6 is disposed at a position substantially the same as or lower than the height of the back glass tube heater 31. The

  Here, the mounting table 6 is positioned by mounting it on a cooking plate 43 made of ceramic or iron plate supported by a guide rail 42 provided on the side surface of the cooking chamber 2.

  A lower reflection member 11 is detachably provided below the mounting table 6. The bottom surface of the lower reflecting member 11 has a plurality of inclined surfaces, and an inclined surface 41 inclined downward from the back side of the cooking chamber 2, that is, from the side close to the back glass tube heater 31, to the front side. The first inclined surface 13 is connected and the tip side is inclined upward, and the second inclined surface 14 has a larger inclination angle than the first inclined surface 13.

  An upper reflecting member 40 is detachably provided on the upper side of the mounting table 6, and is inclined downward from the upper end of the rear opening 33 toward the mounting table 6. At this time, the back side opening (incident opening) formed by the upper reflecting member 40 and the lower reflecting member 11 is set so as to cover all or most of the back opening 33. The lower reflecting member 11 and the upper reflecting member 40 are arranged above and below the mounting table 6 so that surfaces (bottom surfaces) facing each other are substantially parallel. Thereby, the infrared rays generated by the rear glass tube heater 31 disposed at a position where the installation height position is substantially the same as or higher than the mounting table 6 are efficiently guided to the cooking object 5, The side can be heated.

  In this way, by placing the mounting table 6 at a high position in the cooking chamber 2 and installing the upper reflecting member 40 and the lower reflecting member 11 on the mounting table 6, the cooked food 5 is placed on the upper inner flat heater 38 and While being able to make it adjoin to the outer side flat heater 39, it can also heat from the lower side of the foodstuff 5. FIG. For this reason, cooking time can be further shortened.

  When the mounting table 6 is arranged in the upper part of the cooking chamber 2, depending on the ingredients of the cooked product 5, oil or juice scattered by heating tends to adhere to the top surface of the cooking chamber 2, but in the configuration of the fifth embodiment, Cleaning is easy because the top surface of the cooking chamber 2 is not uneven due to the exposure of the heating means.

  Moreover, since the oil and juice falling from the food 5 are supplemented on the lower reflecting member 11, the bottom surface of the cooking chamber 2 can be prevented from being soiled, and cleaning is easy.

  When oil or juice dropped from the cooked food 5 adheres to the lower reflective member 11, the infrared reflection efficiency decreases, but the ratio of the area of dirt attached to the entire area of the bottom surface of the lower reflective member 11 is Since it is small, the heating efficiency is not significantly impaired.

  Moreover, since the lower side reflection member 11 and the upper side reflection member 40 are detachable with respect to the mounting base 6, and the mounting base 6 is detachable from the cooking chamber 2, the dirt adhering to these can be easily cleaned. For this reason, it is possible to reduce the frequency of being left to a state where the heating efficiency is significantly impaired by the user.
