Description

[Detailed Description of the Invention] The present invention mainly relates to an oven-type gas cooker.

Conventionally, this type of cooker includes, for example, the Jikoko 58-
As seen in Publication No. 24086, it is known that the cooker has a cooking chamber with an opening/closing door on the front and a combustion chamber below the cooking chamber with an internal gas burner that is forced to exhaust air. The cooking cabinet has the disadvantage that the flame of the burner is applied to the bottom wall of the cooking cabinet, which tends to cause local overheating on the bottom wall. Conventionally, in order to eliminate such inconveniences, for example, as seen in the above-mentioned publication, a partition plate is provided below the bottom wall, a rectifying plate is provided in front of the bottom wall, and the burner and the burner are provided on the bottom surface of the partition plate. A method has been proposed in which a ventilation gap is formed between the burner flame and the upward drift of the burner flame as much as possible, but the construction of such a method is relatively complicated. I can't escape it.

The purpose of the present invention is to obtain a device that does not have such inconveniences.Inside the cooking device body 1, there is a cooking chamber 3 having an opening/closing door 2 at the front, and below the cooking chamber 3, forced exhaust air is provided by an exhaust fan 4. In the case of a combustion chamber 6 having a gas burner 5 inside, a cavity 8 is provided below the bottom wall 3a of the cooking chamber 3 and is separated from the inside of the combustion chamber 6 by a partition plate 7. This is made to communicate with the outside air through an opening 9 at the end, and a ventilation hole 10 is provided in the partition plate 7 facing above the burner 5.
It is formed by forming.

In the illustrated example, the hot combustion air generated in the combustion chamber 6 is guided directly into the cooking chamber 3 and forcedly circulated within the cooking chamber 3, while a part of it is guided outside through the exhaust port 11. In other words, the exhaust fan 4 is configured to function also as a hot air circulation fan, but the present invention is not limited thereto. The inside of the heating chamber 3 may be heated from its outer periphery, and correspondingly two fans 4, one for exhaust and one for hot air circulation, may be arranged in parallel.

Furthermore, in the illustrated example, the inside of the above-mentioned empty chamber 8 has openings 9, 9 at both ends thereof, and chambers 12, 1 on both outside thereof.
2 to communicate with the outside air in the chambers 12, 12, and the vent hole 10 also acts as a peephole that cooperates with a see-through window 13 previously formed in the bottom wall 3a above it. I did it like that. That is, when the opening/closing door 2 is opened, the operating state of the burner 5 can be seen into the combustion chamber 6 through the see-through window 13 and the vent hole 10 below it.

To explain its operation, when the gas burner 5 is operated, hot combustion air is generated in the combustion chamber 6, which is drawn by the exhaust fan 4 and flows through the chamber 6 as shown by the arrow in FIG. The hot air is guided into the cooking chamber 3 and a predetermined cooking process is carried out in the cooking chamber 3. At this time, the flow of the hot air in the combustion chamber 6 is caused by the partition plate 7 on the upper surface of the combustion chamber 6.
A suction effect is applied to the upper cavity 8 through the ventilation hole 10 formed in the upper part of the cavity 8, and the interior of the cavity 8 is supplied through the opening 9 at the end thereof as shown by the arrow in FIG. As outside air is led in, this in turn vents 1
0 on the gas burner 5 from above. Thus, the empty chamber 8 exists in a state in which outside air is always introduced into the interior thereof, and is interposed between the bottom wall 3a of the cooking chamber 3 above it and the burner 5 below it,
The bottom wall 3a acts to protect the bottom wall 3a from overheating by the burner 5, and the outside air introduced through the vent 10 acts on the flame of the burner 5 from above to prevent it from drifting. In other words, it acts to prevent the bottom wall 3a from being overheated due to the drift.

In this way, according to the present invention, a space 8 is formed under the bottom wall 3a of the cooking chamber 3, separated from the inside of the combustion chamber 6 by the partition plate 7, and the space 8 is formed through the opening 9 at the end of the space 8. A ventilation hole 10 is formed in the partition plate 7 facing the upper side of the gas burner 5 so that the outside air inside the chamber 8 can be freely introduced downward through the ventilation hole 10. The cavity 8 and the ventilation hole 10 are effective in protecting the bottom wall 3a from overheating by the burner 5, and the configuration is sufficient simply by forming the cavity 8 and providing the ventilation hole 10 therein. It has advantages such as being simple and inexpensive.
