DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas blower for a household gas cooker and a gas baking oven.

[0002]

2. Description of the Related Art Conventionally, this type of gas cooker (double-sided gas grill) has an upper grill burner at the top of a baking oven, a grill at the center, a lower grill burner at both sides of the object near the bottom, and a bottom grill at the bottom. It is composed of a soup tray for receiving broth dripped from the object to be cooked. However, in this conventional configuration, when the cooking is performed without putting water in the soup pan and the cooking is performed without forgetting the complexity for uniforming the heat distribution on the lower surface of the object to be cooked, There was a problem that the material was burned up, the oil in the firing chamber was ignited, and a device fire was generated.

A conventional example will be described below with reference to FIG. As shown in FIG. 4, an upper grill burner 2 is provided in an upper part of a baking oven 1, a grill 3 is provided near a center, and lower grill burners 5 and 5 ′ are provided on both sides of a lower part of a food 4. A juice tray 6 for receiving the broth of the food 4 is placed on the bottom. The flame 7 burned by the lower grill burners 5 and 5 ′ and the hot air from the upper grill burner 2 heat the food 4 to be cooked, and then are discharged out of the refrigerator through the exhaust holes 8.

[0004]

However, in this configuration, the heat distribution on the lower surface of the object to be cooked 4 is such that the hot air of the flame of the lower grill burners 5, 5 'rises by natural convection.
If the width of the grill 3 was wide, a uniform heat distribution could not be obtained.
FIG. 4 is a view showing a conventional example. In order to eliminate the above-mentioned drawback, a fan motor 10 is mounted on the upper part 9 of the flame hole 7 of the lower grill burners 5, 5 '.
In accordance with the elapse of the cooking time, the air to be blown was blown with a strong wind or a breeze in a cycle to achieve a uniform heat distribution. However, since the blast air must be installed as close as possible to the upper part of the flame holes 7 of the lower grill burners 5, 5 ',
The structure of the lower grill burner has been complicated and expensive. In addition, since the lower grill burners are placed on both sides of the baking cabinet 1 in terms of maintenance of the baking cabinet 1, it is difficult to perform maintenance.

[0005] Further, if the food is cooked without pouring water into the saucer 6 and the user forgets to cook and is left alone, the oil of the object to be cooked remaining in the saucer becomes hot and ignites and burns in the entire baking oven. There was a danger of going up.

The present invention provides a blower for a gas cooker which has a simple structure and which blows hot air from a lower grill burner having a good bottom surface heat distribution and prevents the juice tray from becoming hot even if water is forgotten to be poured into the juice tray. Its primary purpose is to provide.

[0007] A second object is to connect the grill firing chamber and the blower to the equipment at the time of repairing the equipment, and to supply air into the firing chamber without leaking from the joint without fastening with screws. The present invention is to provide a gas firing chamber provided with:

[0008]

In order to achieve the above-mentioned first object, the present invention provides a baking chamber, in which a blow hole for blowing hot air from a lower grill burner is provided on a part of an inner wall of a baking oven, and a soup tray cooling or oil cutting plate is provided. A cooling hole for cooling is provided, a mounting portion for a blower fan motor is provided adjacent to the firing chamber, a blower duct outer frame having a holding portion for the lower grill burner, and inside the outer frame, at one end, upstream of the lower grill burner. A rectifying unit for regulating and rectifying pressure on the side, a rectifying plate having a diverting portion for diverting the air to the cooling hole at the other end, and a diverting portion for dividing the pressure, and a rectifying plate having a rectifying plate while holding the rectifying plate. A partition plate is provided for separating the combustion chamber downstream of the lower grill burner into a cooling hole provided in a part of the firing chamber.

In order to achieve the second object, the present invention is directed to a baking chamber, in which a part of the vicinity of a ventilation hole and a cooling hole is formed in a concave or convex shape, and a surface of a blowing part of a blowing device adjacent to the baking chamber is formed. And an air passage for contacting each other.

[0010]

According to the present invention, the air blown by the fan motor provided on the upstream side of the lower grill burner is divided into air blown to the combustion chamber by the rectifying plate and air blown for cooling the juice receiving pan or the oil pan. Since the air flow to the member bent at one end to a member having an appropriate opening area, it flows to the lower grill burner held by the air duct outer frame,
The amount of air blown and the distribution pressure of the air are predetermined, and the lower surface heat distribution for the object to be cooked can be made uniform. On the other hand, the cooling air separated by the rectifying plate can also regulate the amount of air to a predetermined amount by an opening provided by the other end of the rectifying plate, and is blown out from a cooling hole provided in the firing chamber, soup tray or Since the oil pan can be cooled by cold air outside the baking oven, it is possible to prevent oil dropped from the object to be cooked from igniting at a high temperature.

Further, the surfaces of the firing chamber and the blowing section can be loosely fitted to each other with an appropriate length overlapping each other.
