BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas blowing device for a domestic gas cooker and a gas firing chamber.

0002

[Prior Art] Conventionally, this type of gas cooker (double-sided gas grill) has an upper grill burner at the top of the firing chamber, a grill grate near the center, lower grill burners near the bottom on both sides of the food to be cooked, and a grill burner at the bottom. It consists of a saucepan that catches the grilling juices dripping from the food being cooked. However, with this conventional configuration, it is complicated to equalize the heat distribution on the bottom surface of the food being cooked, and at the same time, cooking is performed without water being poured into the soup saucer, so if you forget that you are cooking, There were issues such as the risk of things catching on fire, igniting the oil in the kiln, and causing equipment fires.

A conventional example will be explained below with reference to FIG. As shown in FIG. 4, an upper grill burner 2 is provided in the upper part of the baking chamber 1, a grill grate 3 is provided near the center, and lower grill burners 5, 5' are provided on both sides of the lower part of the food to be cooked 4. A soup saucer 6 is placed at the bottom to receive the cooking juice from the food 4. The flame 7 burned by the lower grill burners 5, 5' and the hot air from the upper grill burner 2 heat the food to be cooked 4, and then are discharged to the outside of the refrigerator from the exhaust hole 8.

0004

However, in this configuration, the heat distribution on the lower surface of the food to be cooked 4 is such that the hot air from the flames of the lower grill burners 5, 5' rises due to natural convection.
When the width of the gridiron 3 was wide, uniform heat distribution could not be obtained. FIG. 4 shows a conventional example. In order to eliminate the above-mentioned drawbacks, a fan motor 10 is installed at the upper part 9 of the flame hole 7 of the lower grill burner 5, 5'.
As the cooking time progresses, the air is blown in a cycle of strong or gentle wind to ensure uniform heat distribution. However, since the blown air must be placed as close as possible to the upper part of the flame hole 7 of the lower grill burners 5, 5',
The structure of the lower grill burner has become complicated and expensive. Furthermore, in terms of maintenance of the baking chamber 1, the lower grill burners are placed on both sides of the baking chamber 1, making it difficult to maintain it.

Furthermore, if the soup saucer 6 is cooked without water, and the cooking is forgotten and left unattended, the oil remaining in the soup saucer becomes hot and ignites, causing the entire inside of the baking chamber to catch fire. There was a risk of it rising.

The present invention provides a blower device for a gas cooker that has a simple configuration, blows hot air from a lower grill burner with good heat distribution on the lower surface, and prevents the soup tray from becoming hot even if you forget to put water in the soup tray. The primary purpose is to provide.

[0007] The second objective is to connect the grill oven and the blower to the oven when the equipment is being repaired, and to create an air passage that allows the air to flow into the oven from the joint without leaking, without the need for screws. Our objective is to provide a gas firing warehouse equipped with

[0008]

[Means for Solving the Problems] In order to achieve the first object, the present invention provides a blow hole for blowing hot air from a lower grill burner in a part of the inner wall of the baking chamber, and a cooling pan for soup or a pan for draining oil. A ventilation duct outer frame is provided with a cooling hole for cooling, and has a mounting part for a ventilation fan motor adjacent to the baking chamber, and a holding part for a lower grill burner; A rectifying plate having a rectifying part that regulates and rectifies the pressure on one side, and a dividing part that divides and pressures the air into the cooling hole at the other end, and a rectifying plate that has a rectifying part that divides the air into the cooling hole and divides the pressure, and a rectifying plate that has a rectifying part that regulates and rectifies the pressure at the other end. A partition plate is provided to separate the combustion chamber located downstream of the lower grill burner and the cooling chamber located in the cooling hole provided in a part of the firing chamber.

[0009] In order to achieve the second object, the present invention provides a concave or convex portion of the vicinity of the ventilation holes and cooling holes of the firing chamber, so that the surface of the blowing part of the blowing device adjacent to the firing chamber is formed into a concave or convex shape. A ventilation path is provided in which the two abut against each other.

0010

[Function] With the above-described structure, the present invention divides the air from the fan motor installed upstream of the lower grill burner into air into the combustion chamber and air into the combustion chamber to cool the juice pan or oil pan. After passing through a member with a plurality of bends at one end and an appropriate opening area, the air flows to the lower grill burner held in the outer frame of the air duct.
The amount of air blown and the distribution pressure of the blown air are set to predetermined values, and the heat distribution on the lower surface of the food to be cooked can be made uniform. On the other hand, the cooling air separated by the current plate can be regulated to a predetermined amount by the opening provided at the other end of the current plate, and is blown out from the cooling hole provided in the baking chamber, into the soup tray or Since the oil draining tray can be cooled by the cold air outside the baking chamber, it is possible to prevent oil dripping from the food to be cooked from igniting at high temperatures.

[0011] Further, the surfaces of the firing chamber and the blowing part can be loosely fitted so that they overlap each other by an appropriate length.

0012

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a blower device for a gas cooker and a gas oven according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, the firing chamber 1 is equipped with a grill door 11 that can be opened and closed at the front, an exhaust hole 8 at the upper rear part, and an upper grill burner whose flame forming part is a ceramic perforated plate at the upper part. 2 is provided. Further, at the bottom, there is a soup tray 6 on which a grill 3 on which the food to be cooked 4 is placed is placed. A ventilation hole 12 is provided in a part of the rear wall surface of the baking chamber 1 at a height between the grill 3 and the soup tray 6. This ventilation hole 12 is an opening through which the combustion heat 7 of the lower grill burner 5 burned in the combustion chamber 14 is blown out. Furthermore, cooling holes 13 are provided below the ventilation holes 12 to cool the juice receiving tray 6 and the like. Description will be given below based on FIGS. 1, 2, and 3. FIG. 3 is an overall perspective view of the gas cooker, and FIG. 2 is a diagram of each part of the blower device. The air blown by the fan motor 10 passes through a fan duct 15 and an opening 17 provided at the top of an outer frame 16 (hereinafter referred to as outer frame) of the air duct, one end of which is bent into a plurality of shapes, and an appropriate opening is formed. The current plate 18 has a large area and has an appropriate opening at the other end. The inside of the outer frame 16 is constituted by a partition plate 20 that holds the baffle plate 16 and divides the combustion chamber 14 and the cooling chamber 19. Due to the configuration of the current plate 18 described above, the air that has reached the current plate 18 is divided into the combustion chamber 14 and the cooling chamber 1.
Divided into 9. One end of the current plate 18 is bent into a plurality of parts on the upstream side, and one end of the current plate 18 is bent into a plurality of parts, and each of the parts is Since rectified and pressure-regulated air is introduced through the openings 21 provided in the tongues 18a and 18b, the combustion heat 7 of the lower grill burner gives uniform heat distribution to the lower surface of the food to be cooked.

The air sent to the other cooling chamber 19 passes through the opening 22 provided at the other end 18c of the rectifying plate 18, flows from the cooling chamber 19 to the cooling hole 13, and is stored in the baking chamber 1. This serves to cool the juice tray 6 containing the liquid. This cooling air may also cool the oil draining tray 23 which is normally placed on the soup tray 6. This cooling air prevents the oil dripping from the food being cooked from igniting at a high temperature. Combustion heat 7 from the lower grill burner 5 and combustion exhaust gas from the upper grill burner 2 are discharged to the outside of the firing chamber 1 through an exhaust port 8 provided at the rear upper part.

Next, the connection of the air passage between the baking chamber 1 and the air blower will be explained. The inner wall 24 that comes into contact with the blower section of the baking chamber 1 has a concave shape, and has a concave shape, and has a concave shape.
3, since the outer frame 16 and the partition plate 20 of the blower are loosely fitted to each other by overlapping the appropriate length,
Air in the combustion chamber 14 and cooling air in the cooling chamber are fed into the firing chamber 1 without leaking between the firing chamber 1 and the blower.

Effects of the Invention As described above, in the blower device for a gas cooker according to the present invention, the following effects can be obtained. (1) The lower grill burner is held by the outer frame of the blower and is located inside a combustion chamber made up of a partition plate and a rectifying plate, so it burns by blowing rectified and pressure-regulated air. The heat is homogenized and the heat is evenly distributed over the food being cooked. Uniform heat distribution on the lower surface of the food to be cooked can be obtained with the very simple configuration described above. (2) The cooling air flowing into the baking chamber from the cooling chamber constituted by the outer frame, the baffle plate, and the partition plate cools the soup tray or the oil draining tray. This can prevent high temperature ignition of oil dripping from the food to be cooked. In addition, in the gas firing chamber of the present invention, a part of the surface near the ventilation holes and cooling holes provided in a part of the wall surface of the firing chamber is overlapped with the ventilation device by an appropriate length to provide free space. Since it is fitted, it can be configured without tightening with screws, so when assembling,
and servicing in the event of a breakdown becomes easier.
