DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device for heating an object to be cooked, and more particularly to an apparatus for preventing ignition of fats emitted from an object to be cooked such as fish and meat.

[0002]

2. Description of the Related Art A conventional heating cooker of this type is disclosed in Japanese Unexamined Patent Publication No.
In many cases, such as the structure shown in JP-A-126110, the structure is incorporated in the lower part of a gas table, and the structure shown in FIG. 12 is general. Hereinafter, the configuration will be described with reference to the drawings.

As shown in FIG. 1, reference numeral 30 denotes a gas table which has a built-in heating cooker 31 called a grill at the lower center thereof. The heating cooker 31 is a gas burner 2 provided on the upper surface of a box-shaped heating chamber 32 for radiant heating by infrared rays.
A juice tray 3 which can be put in and taken out from the bottom, a saw net 4 which is placed on the juice tray 3 and on which the food 5 is placed, and a door 35 with a handle 34 attached to the juice tray 3. In the above-described configuration, the actual cooking is carried out by placing an object to be cooked, for example, fish or meat such as saury and horse mackerel on the drape net 4 and putting it in the heating chamber 32 together with the soup tray 3, igniting the gas burner 2 and mainly by radiant heating. Do. Further, the temperature of the juice receiving tray 3 is constantly detected by the temperature detecting sensor 7, and the gas burner 2 is controlled so that the temperature of the juice receiving tray 3 does not abnormally increase.
By controlling the combustion of the fat, the ignition of the fat emitted from the food 5 can be prevented. In addition, this kind of cooker has a soup tray 3
However, in this case, the temperature of the bottom surface of the juice receiving tray 3 does not rise above the boiling point of water and there is no danger of ignition, so the temperature detection sensor 7 also detects this temperature. Then, the gas burner 2 is burned without controlling the combustion amount.

[0004]

In this type of heating cooker, the temperature of the bottom of the juice tray 3 is detected by the sensor 7, but it is difficult to accurately detect the temperature in the following cases. In other words, this is an example in which the user hates the dirt on the juice tray 3 and cooks by laying the aluminum foil 10 on the juice tray 3.
In this case, the aluminum foil 10 is partially in contact with the juice receiving tray 3 but has many floating portions, so that the temperature of the aluminum foil 10 and its vicinity becomes high, and the fat content of the food 5 to be cooked on this surface during cooking. When dropped, it was vaporized and easily ignited, which was very dangerous. At the same time, since the surface of the aluminum foil 10 is smooth and glossy, there is also a characteristic that the radiant heat of the gas burner 2 is reflected. In other words, when the aluminum foil 10 is laid on the juice tray 3, the aluminum foil 10 itself becomes hot, but the bottom of the juice tray 3 below it is blocked by the aluminum foil 10 and cannot absorb the radiant heat from the gas burner 2, The temperature only increased due to slight heat conduction from the contact portion with the aluminum foil 10. Therefore, the temperature detection sensor 7 could not detect the temperature near the surface of the juice receiving tray 3, that is, the surface near the surface of the aluminum foil 10 as distinguished from the case where there is water. If there is an erroneous detection that there is water, there is a problem that the temperature of the juice receiving tray 3 rises abnormally and the fat of the food 5 is ignited.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a structure that can prevent the ignition of fat content of a food to be cooked even when a user lays aluminum foil on a juice tray.

[0006]

[0012]

The present invention has the following effects by the above-mentioned structure.

That is, in the configuration of the heating cooker of the present invention, since the projection plate is provided on the bottom surface of the juice receiving tray, when the aluminum foil is laid, the vicinity of the temperature detection sensor is broken and the bottom surface of the juice receiving tray is exposed, and The temperature of the soup tray can be detected. Further, the control circuit controls the radiant heat source in response to the temperature signal from the temperature detection sensor to prevent ignition of the fat content of the food.

[0014] Further, when a gauze net is placed on a juice tray on which aluminum foil is laid, a heat transfer plate fixed to the same holds down the aluminum foil, and the heat transfer plate absorbs radiant heat to form a juice tray. Since heat is conducted to the bottom surface, the temperature near the bottom of the juice tray can be detected by the temperature detection sensor. Further, the control circuit that receives the temperature signal from the temperature detection sensor controls the radiant heat source to prevent the ignition of the fat content of the object to be cooked.

Further, since the temperature of the bottom surface of the juice tray changes depending on the presence or absence of water in the juice tray, a first temperature detection sensor provided on the bottom surface of the heating chamber detects the temperature and spreads aluminum foil. If so, the second temperature detection sensor detects a rapid temperature change inside the heating chamber, and it can be determined that there is an aluminum foil. Further, the control circuit which receives the temperature signals from the respective temperature detection sensors controls the radiant heat source to prevent the ignition of the fat of the food.

Further, the heat transfer plate fixed to the bottom surface of the juice receiving tray breaks when the aluminum foil is laid on the juice receiving tray and is exposed inside the heating chamber. Therefore, the temperature near the bottom of the juice tray is transmitted to the temperature detection sensor by heat conduction, so that the temperature detection sensor can detect the surface temperature of the juice tray even when the aluminum foil is laid. Further, the control circuit that receives the temperature signal from the temperature detection sensor controls the radiant heat source to prevent the ignition of the fat content of the object to be cooked.

Further, the heat transfer plate fixed to the screen net holds down the aluminum foil on the juice tray and contacts the bottom surface of the juice tray even if the aluminum foil is laid on the juice tray. Therefore, the temperature near the bottom of the juice tray is transmitted to the temperature detection sensor by heat conduction, so that the temperature detection sensor can detect the surface temperature of the juice tray. Further, the control circuit controls the radiant heat source in response to the temperature signal from the temperature detection sensor to prevent ignition of the fat content of the food.

As shown in FIG. 6, when the temperature change detected by the first temperature detection sensor 7 is observed, it is possible to determine whether or not there is water, because the gradient is clearly different. It is difficult to distinguish from the case with the temperature detected by the first temperature detection sensor 7. Next, as shown in FIG. 7, there is a characteristic change in the temperature detected by the second temperature detection sensor 12. That is, the air in the heating chamber is heated by the radiant heat reflected by the aluminum foil 10, and the temperature rises sharply as compared with the case where the heat is absorbed by the juice receiving tray 3 or water.
