Abstract

PURPOSE:To make heating for cooking uniform by installing first and second sirrocco fans to be rotated in an inner section of an oven back-to-back in parallel, and sucking combustion hot air generated from a burner to the first sirrocco fan through a suction port of a flue. CONSTITUTION:A hot air passage 16 formed of a flue 13, an outer wall and an inner partition wall 15 to bend a hot air flowing direction and a hot air vent hole 17 opened at the wall 15 are provided in an oven chamber 12 having a burner 11. Further, a first sirrocco fan 18 for circulating hot air into the chamber 12 through the passage 16 and the hole 17 and a second sirrocco fan 19 for circulating the hot air into the chamber 12 are installed back-to-back in parallel to hold rotations. Thus, the hot airs of optimum flow rate are circulated uniformly in the chamber by the first and second fans to improve a thermal efficiency in the housing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air circulation system in a gas oven chamber (hereinafter abbreviated as oven chamber).

[0002]

2. Description of the Related Art A gas oven which employs a hot air circulation system is advantageous in that it can simultaneously cook a large amount of various foodstuffs regardless of the content of cooking. For example, as shown in FIG. 1, the hot air of the burner is sucked into the sirocco fan 2 installed in the oven chamber 1 from the intake of the flue, and the rotation of the sirocco fan 2 circulates the hot air in the oven chamber 1. This hot air heats and cooks the food placed on the vat 3 in the oven chamber 1 to improve cooking efficiency.

[0003]

However, in the method of directly circulating hot air in the oven using such one conventional sirocco fan 2, the hot air circulation path in the direction of the arrow in FIG. 1 is used. Despite the formation of the above, specifically, since the upper right position 4a of the upper bat 4 and the lower left position 5a of the lower bat 5 are locally heated to high temperature, the cooking placed on the upper butter 4 and the lower butter 5 is performed. There was a problem that the ingredients were unevenly baked.

[0004]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this object, in the present invention, the first inner part of the oven is rotated. A first sirocco fan and a second sirocco fan are installed side by side in parallel, and the first sirocco fan in the oven chamber is connected to the burner provided in the oven through the intake port of the flue connecting to the burner. To aspirate
By the rotation of the first sirocco fan, this hot air is formed by the outer wall and the inner partition wall of the oven chamber, and a hot air flow path that bends the flow direction of the hot air and a hot air passage hole formed in the inner partition wall of the oven chamber are formed. Hot air circulation in the gas oven chamber, in which hot air is supplied to the inside of the oven chamber through the above, and the hot air supplied to the oven chamber is circulated in the chamber by the rotation of the second sirocco fan. Provide a scheme.

[0005]

Therefore, in the hot air circulation system in the oven according to the present invention, the hot air supplied from the flue connected to the burner is forcibly sucked by the first sirocco fan, and as shown in the direction of arrow A in FIG. It is supplied to the inside of the oven through a hot air flow path formed by the outer wall and the inner partition of the oven and bent in the flow direction of the hot air and a hot air passage hole formed in the inner partition. The hot air supplied into the oven chamber is circulated in the direction of arrow B in FIG. 2 by the rotation of the second sirocco fan. Therefore, the optimum amount of hot air is circulated in the oven chamber to make the temperature inside the oven uniform, and as a result, the uneven cooking of the cooking ingredients due to the local heating described at the beginning does not occur.

[0006]

Embodiments of the present invention will be described with reference to FIGS. The present invention, as shown in FIG. 2 and FIG.
Flue 13 (hot air inlet) in oven chamber 12
And a hot air passage 16 formed by the outer wall 14 and the inner partition wall 15 of the oven chamber 12 and bent in the flow direction of the hot air, and a hot air passage hole 17 formed in the inner partition wall 15.
And are installed in parallel back to back and maintain the same rotation, and the hot air passage 16 and the hot air passage hole 17 of the internal partition wall 15 are provided.
A first sirocco fan 18 for circulating hot air in the oven chamber 12 and a second sirocco fan 19 for circulating the hot air in the oven chamber 12 through the first sirocco fan 18 and the second sirocco fan. The fan 19 uniformly circulates the optimum amount of hot air in the oven cabinet 12 to improve the thermal efficiency in the oven cabinet 12.

2 and 3, reference numeral 20 is a motor,
Reference numeral 21 is a front door of the oven, 22 is a top plate of the oven, and 23 is a cooking ingredient in the oven. Since the temperature of the entire oven interior differs depending on the type of cooking ingredients to be heated, it is necessary to adjust the temperature inside the oven in accordance with the cooking ingredients, and the oven may be provided with a heating temperature control mechanism.

[0008]

As described above, according to the present invention, the first sirocco fan and the second sirocco fan, which rotate in the inner part of the oven, are installed side by side in parallel, and the burning hot air generated by the burner provided in the oven is installed. Is sucked by the first sirocco fan in the oven via the air inlet of the flue connected to the burner, and the hot air is formed by the outer wall and the internal partition of the oven by the rotation of the first sirocco fan, The hot air is bent in the flow direction of the hot air and the hot air is supplied through the hot air passage hole formed in the inner partition wall of the oven to the inside of the oven, and the hot air supplied to the oven is aforesaid. Since the hot air circulation system in the gas oven chamber forms a circulation path of hot air so as to circulate in the chamber by the rotation of the second sirocco fan, the thermal efficiency in the oven chamber is the same as that of the conventional hot air circulation system. Further improved compared with the expression, it is possible to achieve uniform cooking food cooking heating by hot air is uniformly circulated within the oven chamber.
