Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating cooking device particularly suitable for stir-frying.

Conventionally, heating cooking devices for making yakisoba or fried rice, for example, have basically been equipped with a pot that houses food to be cooked, and a heating section that is located below the pot and consists of a gas burner that heats the pot. The food to be cooked inside the pot is heated by heating the pot with combustion heat emitted from the heating section.

By the way, when making yakisoba, for example, the foods to be cooked stored inside the pot include vegetables such as cabbage, meat, etc. in addition to noodles for yakisoba, and these foods are heated and cooked as described above. When cooking in the pot of the device, moisture may seep out from the vegetables, so there may be a lot of moisture inside the pot. Since water and sauces are added at the same time, a large amount of moisture remains inside the pot and the entire food, resulting in a so-called stuffy finished product. Moreover, such problems often occur when using the above-mentioned conventional heating cooking device to make fried rice, etc., when roasting beans, or when roasting small fish (such as jiyako) to bring out their aroma. Ta. Here, it is possible to make stir-fried foods with less water content by increasing the heating time, but in this case, the flavor deteriorates due to over-frying, and moreover, the cost increases due to increased fuel consumption. , the cooking time will also be longer.

The present invention has been made in view of the above circumstances, and its purpose is to enable cooking to a good finished state with less moisture when performing heat cooking such as stir-frying or roasting, and to do so while reducing fuel consumption. An object of the present invention is to provide a heating cooking device that can achieve the desired heating results.

An embodiment of the present invention will be described below with reference to the drawings. 1 is the main body case, which is the partition plate 1a

In FIGS. 2 and 3, reference numeral 9 denotes a rotation operating device provided on the cover member 5 of the main body case 1, which is connected to the handle 10.
and its handle shaft 11 and one support shaft 7 of the pot 6.
The pot 6 is configured to rotate the pot 6 between the solid line position and the two-dot chain line position in FIG. 1 by rotating the handle 10. In FIG. 1, reference numeral 13 denotes a stirring body having two impellers 14 and 15, and this is supported by supporting the stirring shaft 16 on a bearing unit 17 attached to the outer surface of the pot 6. 6 and is rotatably provided. On the other hand, in the lower part of the machine room 3, a motor 18 for driving the stirring body 13 is provided, and in the upper part, a power transmission shaft 19 is provided via bearing units 19a, 19a. The transmission shaft 19 receives the rotational power of the motor 18 via a belt transmission mechanism 20. and the power transmission shaft 1
A driving gear 21 is connected to 9, and this driving gear 21 meshes with a driven gear 22 attached to the stirring shaft 16, so that the stirring body 13 is rotationally driven by the motor 18. ing. Thus, the driven gear 22 separates from and meshes with the drive gear 21 as the pot 6 rotates in the directions of arrows A and B in FIG. Note that 22a is a gear cover. Reference numeral 23 denotes a heat source, for example, a gas burner, which is installed in plurality in an upright manner in the combustion chamber 2, which is the lower part of the pot 6, and its flame nozzle 23a is oriented to directly hit the bottom surface of the pot 6. . 24 is a cylindrical cover provided to surround these gas burners 23.

Now, 25 is an air supply device, which will be described below. That is, 26 is the partition plate 1 which is the side wall of the combustion chamber 2.
This intake port 26 is connected to an intake cylinder 27 that projects into the machine room 3. Reference numeral 28 denotes a blower, which is composed of a spiral-shaped casing 29, blades (not shown) provided in the casing 29, and a fan motor 30 that rotationally drives the blades.
8, the suction port 29a of the casing 29 is connected to the suction cylinder 27, and the discharge port 29b faces upward, and a connecting cylinder 31 is connected to the discharge port 29b. Reference numeral 32 denotes a connecting pipe that communicates the connecting cylinder 31 with the inside of the pot 6, the upper end of which is connected to an air outlet 33 formed in the upper wall of the pot 6.
Further, the lower end portion is separably fitted and connected to the connecting tube 31. Reference numeral 34 denotes a damper for adjusting the amount of hot air having an L-shaped cross section, which is installed vertically and vertically in the middle of the intake pipe 27, so that the damper 34 for adjusting the amount of hot air can move up and down. By setting the movement angle, the opening ratio of the upper and lower halves of the intake cylinder 27 can be changed. Further, 35 is a damper for adjusting the amount of air supplied, which is slidably provided on the connecting cylinder 31, and by sliding, the connecting cylinder 3
The opening area of 1 can be changed. 36 is an exhaust pipe, which is led out from the combustion chamber 2 through the machine room 3 to the outside of the main body case 1.

The operation of the above configuration will be described. For example, when making yakisoba, place noodles for yakisoba in the pot 6 as well as vegetables such as cabbage, meat, and other foods to be cooked, and then
The gas burner 23 is ignited, the motor 18 is rotated, and the fan motor 30 is further rotated. Then, the combustion flame from the flame nozzle 23a of the gas burner 23 directly hits the outer bottom of the pot 6, and the pot 6 is heated by the fuel heat, and the stirring body 13 is heated inside the pot 6 based on the rotation of the motor 18. Furthermore, based on the rotation of the fan motor 30, the air in the combustion chamber 2 is sucked into the intake cylinder 27 from the intake port 26, and forced into the pan 6 from the discharge port 33 through the casing 29, the connecting cylinder 31, and the connecting pipe 32. sent to. In this case, the hot air amount adjusting damper 34 is in a rotational position where the upper half and lower half of the intake cylinder 27 have an opening ratio of approximately 1:1. Here, in the combustion chamber 2, the air surrounding the gas burner 23 is heated by the heat of the gas burner 23, and hot air is generated. The hot air is mainly sucked through the upper half of the intake pipe 27 as shown by arrow C in FIG. The air is sucked in as shown by arrow D, and hot air whose temperature has been adjusted to, for example, about 150° C., is sent into the pan 6 by room temperature air. As can be seen from the above, the food to be cooked inside the pot 6 is stirred by the stirrer 13, exposed to the above-mentioned hot air, and subjected to the combustion heat of the gas burner 23 to be cooked, that is, stir-fried. During this process, moisture in the pot 6 increases due to moisture seeping out from the vegetables, water for loosening the noodles, and addition of sauce, etc. However, according to this embodiment, the moisture content increases. The hot air sent by the air device 25 can evaporate the moisture, and as a result, fried noodles (stir-fried food) with less moisture and a good finish can be made. Moreover, in this case, the hot air that is inevitably generated around the gas burner 23 is used for the above-mentioned water evaporation, instead of being exhausted as it is as is in the conventional case.
can be used as is to make stir-fried food with a good finish without increasing the thermal power, etc., and as a result, the exhaust heat of the gas burner 23 can be used effectively, that is, the thermal efficiency of the gas burner 23 can be increased, and fuel consumption can be reduced. There will be no increase in volume and hence an increase in fuel costs, and
Since there is no need to increase the heating time, there is no need to over-fry, which prevents the taste of the stir-fried food from deteriorating.

Note that the heating cooking device of the present invention can be applied not only to making fried noodles but also to making fried rice, roasting beans, or roasting small fish (such as jiyako).

As is clear from the above description, the present invention includes a pot,
A heating cooking device comprising: a heat source provided at the lower part of the pot to heat the pot; and an air supply device that sucks hot air generated around the pot by the heat source and sends it into the inside of the pot. With this, when making stir-fried foods, etc., it is possible to achieve a good finish with less moisture, and this can be achieved by using the hot air that is inevitably generated around the heating part and which was conventionally exhausted. Therefore, the thermal efficiency of the heating section can be increased, fuel consumption and fuel costs can be reduced, and there is no need to newly install another heat source, which can also prevent a rise in costs.Furthermore, heating time can be increased. This has excellent effects, such as preventing deterioration of taste.
