Description

  The present invention relates to a heating cooker that heats cooked objects such as fish.

  As this type of heating cooker, for example, there is a heating cooker provided with a heating source for upper cooking such as an upper fire burner on the ceiling in a grill cabinet like a grill provided in a gas stove. In such a grill, when cleaning the inside of the grill cabinet, the heating source for upper cooking is exposed in the upper portion of the grill cabinet, so that it is difficult to clean the grill cooking hook or the like on the heating source for upper cooking. Met.

By the way, in some gas grills, a radiation prevention plate for blocking radiation from the upper fire burner is provided between the upper fire burner and the grill (Patent Document 1). This gas grill heats and cooks the food to be cooked on the grill net by the heat of the combustion exhaust trapped in the grill cabinet while blocking the radiant heat from the upper burner (Patent Document 1, paragraph 0005, etc.).
Moreover, although it is a steam cooker which heat-cooks with superheated steam, there exist some which provided the gas temperature rising heater in the space behind the ceiling of a heating chamber, and provided the panel in which the several fumarole was formed in the ceiling (Patent Document 2). This steam cooker performs heating cooking by ejecting superheated steam heated by the gas temperature raising heater into the heating chamber from the nozzle holes of the panel, but heats the panel by generating heat from the gas temperature raising heater without steam. Thus, this panel allows heat to be cooked by radiating and radiating heat into the heating chamber (paragraph 0093, etc. of Patent Document 2).

  As described above, in the cooking devices of Patent Documents 1 and 2, the upper part in the grill is not exposed to the upper cooking heat source by the plate (the radiation prevention plate or the panel). The top of the can also be easily cleaned. However, it has been difficult to use the radiant heat from the upper cooking heat source for cooking the food to be cooked by installing the plate.

  That is, the radiation prevention plate in Patent Document 1 is provided with a plurality of small holes (holes 2b). These small holes are holes for allowing combustion exhaust gas in the grill box to pass therethrough. The radiant heat from the upper cooking heat source (burner 40) is not sufficiently passed (paragraph 0011 of Patent Document 1). Further, the panel in Patent Document 2 is also provided with a plurality of fumaroles (fumarole holes 43). These fumaroles vigorously move the superheated steam downward so that the superheated steam collides with the object to be cooked. These holes are provided for jetting (paragraph 0078 of Patent Document 2), and the radiant heat from the upper cooking heat source (gas heating heater 41) cannot be sufficiently passed. Accordingly, since most of the radiant heat from the upper cooking heat source is blocked by the plate body, these cooking devices cannot be expected to have a baking performance that can cause the food to be burnt.

  This invention is made | formed in view of the said situation, and provides the heating cooker which can clean the inside of a grill | warehouse | chamber easily, without reducing the baking performance of the to-be-cooked object by the heating source for upper cooking. Let it be an issue.

The heating cooker according to the present invention is
In a heating cooker provided with a heating source for upper cooking on the ceiling part of the grill cabinet for storing the food to be cooked,
The upper part in the grill is a storage room in which a heating plate is provided under the upper cooking heat source and the upper cooking heat source is stored.
The hot plate is formed with a through hole that transmits radiant heat downward from the upper cooking heat source so as to face at least the heat radiation portion of the upper cooking heat source ,
An exhaust passage is connected to the rear part of the storage room to discharge oil smoke generated from the cooking object in the grill to the outside, and the oil smoke generated from the food object is introduced into the storage room through each through hole of the hot plate. After combustion with a cooking heat source, the exhaust passage is discharged to the outside .

With the above configuration, the upper cooking heat source is covered with the hot plate and is not exposed in the grill cabinet, so the upper portion in the grill cabinet is configured smoothly with the hot plate. Therefore, when cleaning the inside of the grill, the upper part of the grill can be easily cleaned because the cloth is not caught by the upper cooking heat source. Moreover, since a through hole is formed in the hot plate along at least the shape of the upper cooking heat source, the radiant heat from the upper cooking heat source is radiated from the through hole toward the object to be cooked. An object can be cooked well so that the surface is burnt.
Furthermore, since the exhaust passage is not connected to the wall surface in the grill cabinet that accommodates the food to be cooked, the wall surface in the grill cabinet can be configured more smoothly, and the cleanability in the grill cabinet can be further improved. . In addition, the oily smoke generated from the cooking object in the grill is introduced into the storage chamber from each through hole of the hot plate, burned by the upper cooking heat source, defrosted and debrominated, and discharged from the exhaust passage to the outside. can do.

The upper cooking heat source is composed of a linear electric heater,
It is desirable that a plurality of through holes having a diameter larger than the diameter of the electric heater be formed in the hot plate.
This makes it possible to improve the cleanability of the upper part in the grill cabinet by the hot plate, and to reliably radiate the radiant heat from the electric heater toward the cooked food from the through hole of the hot plate, thereby bringing the cooked food to the surface. It can be cooked well so that it can be burnt.

The upper cooking heat source consists of a gas burner,
The hot plate may be formed with a through hole that is opened along the heat dissipation portion of the gas burner.
Also in this case, the hot plate can improve the cleanability of the upper part in the grill cabinet, and the radiant heat from the gas burner is reliably radiated from the through hole of the hot plate toward the cooked item, so that the cooked item is brought to the surface. It can be cooked well so that it can be burnt.

Also, if the upper cooking heat source is composed of a gas burner,
The hot plate is preferably provided with an air intake for introducing external air from the outside of the grill to the storage room.
Thereby, external air can be supplied to a gas burner as combustion air, and combustion of a gas burner can be performed favorably. Moreover, since the combustion air is introduced into the storage chamber without going through the inside of the grill, the temperature in the grill can be prevented from lowering due to the combustion air, and the cooking object can be cooked well. it can.

As described above, according to the heating cooker according to the present invention, by configuring the hot plate as described above, the radiant heat from the upper cooking heat source can be sufficiently dissipated to the lower cooking object, and The upper part in the grill can also be easily cleaned. Therefore, the cleanability in the grill can be improved without deteriorating the baking performance of the food to be cooked by the upper cooking heat source.
Furthermore, since the exhaust passage is not connected to the wall surface in the grill cabinet that accommodates the food to be cooked, the wall surface in the grill cabinet can be configured more smoothly, and the cleanability in the grill cabinet can be further improved. . In addition, the oily smoke generated from the cooking object in the grill is introduced into the storage chamber from each through hole of the hot plate, burned by the upper cooking heat source, defrosted and debrominated, and discharged from the exhaust passage to the outside. can do.

The grill device 2 is provided inside the gas stove 1, and includes a grill cabinet 3 for cooking food to be cooked such as fish, and an upper electric heater (upper part) assembled to the ceiling portion 31 of the grill cabinet 3. (Heating source for cooking) 41 and a lower electric heater (lower heating source for cooking) 51 assembled to the bottom surface portion 32 of the grill 3. An openable and closable grill door 33 is attached to the front surface of the grill cabinet 3, and the front opening of the grill cabinet 3 is opened and closed by sliding the grill door 33 back and forth. A grill pan 6 is disposed in the grill cabinet 3, and the food to be cooked placed on the grill pan 6 is cooked by the upper electric heater 41 and the lower electric heater 51. The grill pan 6 is supported by a support frame 9 attached to the grill door 33, and is moved in and out of the grill cabinet 3 by moving the grill door 33 back and forth.

  The grill cabinet 3 has a substantially rectangular parallelepiped shape with an open front surface, and is formed of a thin steel plate. The inner wall surface of the grill cabinet 3 is preferably subjected to fluorine coating or catalyst coating so that the attached dirt can be immediately wiped off. Moreover, it is preferable that the inner wall member of the grill cabinet 3 is made of stainless steel having excellent strength.

  The upper electric heater 41 is constituted by a sheathed heater (for example, power consumption 700 W with an AC 100 V power supply) curved in a meandering manner, and is disposed in the vicinity of the ceiling portion 31 of the grill cabinet 3. For example, the upper electric heater 41 having a diameter of 6.5 mm is used. When the upper electric heater 41 generates heat, the food to be cooked placed on the grill pan 6 is heated from above by the radiant heat from the upper electric heater 41.

  The lower electric heater 51 is configured by a meandering or circular sheathed heater (for example, power consumption of 700 W with an AC 100 V power source). A flat radiator 52 that is heated by the lower electric heater 51 is disposed above the lower electric heater 51. The planar heat dissipating body 52 is formed of a casting in which a metal having excellent thermal conductivity such as aluminum, aluminum alloy, copper, or copper alloy is cast. The flat radiator 52 is formed in a disk shape having a size that covers the lower electric heater 51 and covers the opening 35 formed in the bottom surface portion 32 of the grill 3. Accordingly, the lower electric heater 51 is disposed below the bottom surface portion 32 so as not to be completely covered with the flat radiator 52 and exposed to the grill cabinet 3, and only the upper surface of the flat radiator 52 is exposed to the grill cabinet 3.

Accordingly, since the upper electric heater 41 is not exposed to the upper portion in the grill cabinet 3 by the hot plate 7a, the cloth width is not caught on the upper electric heater 41 when the inside of the grill cabinet 3 is cleaned. Easy to clean.

  As shown in FIGS. 2 to 4, the heat plate 7 a has a rectangular shape, and a large number of circular through holes 71 a are densely formed along the meandering shape of the upper electric heater 41. The size of each through hole 71a is slightly larger than the diameter of the upper electric heater 41, and is formed to a size that does not catch a human finger. For example, if the diameter of the upper electric heater 41 is 6.5 mm, the hole diameter of the through hole 71a is preferably 8 mm. By making the size of the through holes 71a in this way, most of the radiant heat directed downward from the upper electric heater 41 passes through each through hole 71a and is radiated into the lower grille 3. The shape of each through hole 71a is not limited to a circle, but may be a polygonal shape such as a hexagon or an octagon. For example, when the shape of the through hole 71 a is a hexagon, it is preferable that the distance between the opposing sides is larger than the diameter of the upper electric heater 41.

  Thus, the heat plate 7a is formed with a large number of through holes 71a along the meandering shape of the upper electric heater 41, and the diameter of each through hole 71a is larger than the diameter of the upper electric heater 41. The radiant heat of the heater 41 is not blocked by the hot plate 7a, but is radiated into the grill 3 through each through hole 71a. Therefore, the cooking object on the grill pan 6 can be sufficiently heated and cooked so that the surface is burnt by the radiant heat of the upper electric heater 41.

  Further, since the through hole 71a of the hot plate 7a is not formed in a portion that does not face the upper electric heater 41, it prevents the grease or the like scattered from the cooking object in the grill 3 from entering the storage chamber 36. Thus, the inside of the storage chamber 36 and the upper electric heater 41 are hardly contaminated. The hot plate 7a is made of a metal such as stainless steel or aluminum having excellent heat dissipation. Moreover, it is preferable to apply black coating to the surface of the hot plate 7a. By applying black coating, a heat radiation effect by far-infrared rays can be obtained and cooking of the food to be cooked can be performed satisfactorily.

  The exhaust passage 8 is connected to the rear portion of the storage chamber 36 and communicates with an exhaust port formed on the upper surface of the rear portion of the top plate 11 (see FIG. 1). A plurality of exhaust outlet holes 82 are formed in the partition plate 81 between the storage chamber 36 and the exhaust passage 8 (see FIG. 2). A catalyst (not shown) is disposed on the rear side (exhaust passage 8 side) of the partition plate 81. Therefore, the oil smoke generated from the cooking object being cooked in the grill 3 flows into the storage chamber 36 from each through hole 71a of the hot plate 7a, is burned by the upper electric heater 41, and further is a catalyst (not shown). In other words, the smoke is deodorized and debrominated and exhausted from the exhaust passage 8 to the outside.

  According to the grill device 2 of the first embodiment described above, the upper electric heater 41 is covered with the hot plate 7a and is not exposed in the grill cabinet 3, and the upper portion in the grill cabinet 3 is configured smoothly by the hot plate 7a. . The lower electric heater 51 is also covered with the flat radiator 52 and is not exposed in the grill cabinet 3, and the bottom surface of the grill cabinet 3 is constituted by the bottom portion 32 and the flat radiator 52. Further, since the exhaust passage 8 is connected to the storage chamber 36, the rear wall in the grill cabinet 3 is also configured smoothly. Therefore, since the inside of the grill cabinet 3 is configured to be substantially smooth on the top, bottom, left, right, and rear wall surfaces, the inside of the grill cabinet 3 can be easily cleaned with a cloth or the like, and the cleanability within the grill cabinet 3 is improved. be able to. In addition, since a large number of through holes 71a are formed in the hot plate 7a along the shape of the upper electric heater 41, the radiant heat from the upper electric heater 41 can be radiated from the through holes 71a to the object to be cooked. Thus, the food to be cooked can be cooked well so that the surface is burnt.
