  Patent Document 1 is a skewer that is automatically operated and easy to clean, and is a skewer that is formed so that an air passage is formed between the inner casing and the outer casing. The inner casing and the outer casing are separated from each other. It is easy to remove the oil layered in the air passage, and the to-be-baked item is boiled by fire at the lower part while the skewer set on the stationary part is rotated by a mechanism such as a cam and gear, and near the upper part. It is described that it is a skewer that can boil from a weak fire while being stabbed with infrared rays, and it can be cooked uniformly, but the baked item is boiled in the fire at the bottom and near infrared is stabbed at the top However, there is no description of the heating means method of cooking from a weak fire, and the characteristic of the baking apparatus of the prior document 1 is a skewer characterized by the mechanism of oil removal and rotation and movement of skewered food.

  Patent Document 2 is a pottery for grilling yakitori, skewers, etc., and in order to prevent the sauce dripped off during baking, a heat-resistant plate glass is installed on the heating element to protect the heating element. This is a grill that burns yakitori above the heat-resistant plate glass, and the heating element can be protected from dripping, but the thermal conductivity of quartz glass is about 1.16, and the heat generated by the heating element is transferred to the outside of the heat-resistant plate glass. The heat transfer efficiency for baking the grilled food is not good, and the oil and fat dripped on the heat-resistant glass inhibits the amount of heat generated on the surface of the heating element, the dripped oil and sauce burns, and the smoke deteriorates the taste of the food. There is a harmful effect.

  The baking apparatus in the prior art document 1 and the prior art document 2 and the skewer food baking apparatus which is widely used generally depends on the fact that the heat source for baking is located below the skewer food product. The skewered food baking apparatus of the present invention is used to solve the problems of obstructing the generation of heat due to dripping oil and sauce and sacrificing food taste due to burning and scorching of dripping oil and sauce. I will provide a.

  The skewer food baking apparatus according to the present invention includes a flame intake box A, a hot-air discharge box B, a fat and oil receiving tray C, and a gas burner, as shown in the enlarged perspective view of the skewer food baking apparatus shown in FIG. A skewer food baking apparatus comprising D and an apparatus stand F, wherein the flame intake box has a rectangular shape with an opening at the bottom, and a number of small hot air discharge equalization holes are provided on the upper surface of the rectangular shape to capture the flame. A gas burner with an appropriate number of small combustion holes provided at an appropriate pitch is installed at the lower position of the box, and a high-temperature hot air is generated by a gas combustion flame and an air flow with a rising speed generated by the high temperature of the combustion flame. Are connected to a flame intake box, and a hot air discharge box having the same shape as the flame intake box having a lower opening is connected to the upper surface of the flame intake box. Flame removal Capturing homogenized hot with hot air ejection uniformity Kaana of seeing a box body.

  The hot air discharge box is provided with an appropriate number of small hot air blowing slots having a rectangular shape at a constant pitch between the front and back in the longitudinal direction at the upper end position and the lower end position on both side surfaces thereof.

  The air volume adjusting mechanism portion of the hot air discharge box has a discharge air volume adjusting plate provided with a hot air blowing long hole having the same shape as the hot air blowing long hole of the hot air discharging box on the outer surface of the hot air blowing long hole of the hot air discharge box. Install closely. Attach the discharge air volume adjustment plate mounting screw shaft to the front end of the discharge air flow adjustment plate, and install it by screwing it onto the screw shaft nut cradle attached to the front end plate of the hot air discharge box, and then attach the handle to the front end of the screw shaft By turning the handle, the discharge air volume adjustment plate can be slid back and forth by screw threading with the nut boss, and the overlapping part of the opening area of the hot air discharge box long hole and the opening area of the discharge air volume adjustment plate is enlarged. The amount of air discharged to the skewered food can be adjusted to enable proper baking.

  The wind direction rectifying mechanism of the hot air discharge box has a wind direction locked to a shaft at the head position of the long hole on the outer surface of the long hole provided at the upper side position of the side surface of the hot air discharge box. A rectifying upper plate is installed, and a wind direction rectifying lower plate that is locked to the shaft is installed at the lower position of the long hole, and each shaft can be inserted into the front and rear bearing bosses before and after the hot air discharge box and turnable. To do. A handle is attached to the front end of each shaft. Set the set screw at the upper position of the bearing boss of the wind direction rectification upper plate shaft, and set the set screw, while the set screw and screw at the bottom of the bearing boss of the shaft for the wind direction rectification lower plate Set up a screw that can be engaged, and set the set screw there. Turn the handle of the wind direction rectifying upper plate mounting shaft and the handle of the wind direction rectifying lower plate mounting shaft to adjust the flow of hot air discharged from the hot air discharge hole at the upper position of the hot air discharge box to the upper position of the skewer food. Then, the angle at which the firing can be properly performed is adjusted, and then the inclination angle of each wind direction rectifying upper plate is set with a set screw.

  Also on the outer surface of the long hole provided at the lower side position of the hot air discharge box, the inclination angle of the lower wind direction rectifying upper plate and the lower wind direction rectifying lower plate is adjusted appropriately as in the above 0010, and the hot air is skewered food It is set so that it can be properly discharged and baked appropriately. The upper wind direction rectifying upper and lower plates and the lower wind direction rectifying upper and lower plates can be rotated independently and set individually, so that hot air can be discharged appropriately to the head area, lower area and both sides of the skewer food, Therefore, appropriate baking can be performed with high heat efficiency without baking the skewered food as in the past.

  A gas-fired flame generates an air flow with an ascending speed at the same time as gas combustion due to the supply gas itself having a discharge pressure and a high flame combustion temperature (generated by charcoal combustion heating or heater heating). It is much faster than the rising hot air), and the updraft hot air is taken into the flame intake box at a rising speed and blown out at a flow velocity from the hot air discharge box, and it is necessary to discharge from the hot air blowing slot from the hot air generation point The heat loss due to heat dissipation in the middle is extremely low because it takes less than 1 second and the hot air can be blown to the skewer food at an unparalleled distance from the hot air outlet to the skewer food. The baking heat transfer efficiency is very low and the skewer food can be baked.

  Since the heat source of the skewered baking apparatus of the present invention is not at the lower position of the skewered food, an oil receiving tray dish that receives oil and sauce dripping below the grilled food can be installed, and the oil and sauce dripping during baking can be installed. Does not hinder the amount of heat generated by the heat source.

In general, in the case of skewers, when the heat source is baked with a heater inserted into the charcoal fire or quartz tube, the heat source is installed at the lower position of the skewered food and the heat is baked with charcoal fire. When the skewered foods are fired, fats and sauces drop on the burning charcoal and inhibit the combustion of the charcoal, or the dripped fat and sauce burns or burns and smells unpleasant , The odor of which makes it unpleasant, and makes it difficult to extinguish and clean up the charcoal fire when firing is completed. This phenomenon occurs in the same way when using a quartz tube with a built-in heater and firing with the heat generated by the built-in heater. However, the skewer of the present invention has no heat source below the skewered food, so the heat source is oil and fat during firing. It does not suffer from dripping of oil and sauce, and dripping of oil and sauce during baking is received by the oil receiving tray installed at the lower position, so it only needs to clean the oil receiving tray after baking and the entire baking machine Cleaning up is much easier than with a traditional baking machine.

  Since the hot air rectified by the wind direction rectifier plate is blown directly on the top surface area, both side surface area, and bottom surface area of the skewered food with an appropriate inclination angle from both sides, the whole can be baked without turning the skewered food, The wind direction rectifier can adjust the inclination angle of the wind direction rectifier plate independently by the wind direction rectifier mechanism part for each of the upper wind direction rectification upper plate, the upper wind direction rectification lower plate, the lower wind direction rectification upper plate, and the lower stage wind direction rectification lower plate. Therefore, the hot air suitable for baking can be discharged to the whole skewered food, and the amount of hot air suitable for baking to the skewered food can be adjusted by adjusting the air volume adjusting plate of the air volume adjusting mechanism part, so the skewered food Without turning the food, hot air suitable for the shape of the skewered food can be supplied to the upper surface area, both side areas, and the lower surface area of the skewered food, and can respond to different sizes of skewered food.

  The hot air with the flow velocity blown from between the upper and lower wind direction rectifying plates installed at the upper and lower positions of the hot air blowing slot of the hot air discharge box has the flow velocity and the upper and lower rectifying plates Has the function of extending the discharge flow rectifying area along the rectifying plate from the upper and lower rectifying plate ends, and the inclination angle of the rectifying plate can be adjusted individually and fixed together with the appropriate area of the skewer food. Blowing hot air can be applied. When there is no wind direction rectifying plate, the hot hot air discharged from the long hole on the side of the hot air discharge box rises immediately and it becomes difficult to properly heat and bake the skewered food. By properly setting the inclination, the whole food can be properly baked without rotating the skewered food.

In general, the baking heating temperature of skewered foods is 120 to 150 ° C., and the hot air for baking can be blown from a distance very close to the skewered foods. For example, when baking foods on a hot plate Although the heat plate temperature suitable for the heat plate is 120 to 150 ° C, the heat applied to the heat plate is immediately dissipated from the surface of the hot plate in all directions. The temperature supplied to the back surface of the hot plate generally requires a heat amount of 400 to 500 ° C. In addition, the heat transfer area where the food is in contact with the hot plate is very small, and most of the heat from the hot plate is dissipated without being transferred to the food, so the heat efficiency is very poor. When the skewer food is baked by burning, the amount of heat transferred to the skewer food is much less than the amount of heat dissipated without transferring heat to the skewer food, and the heat transfer efficiency is poor.
In the skewer food baking apparatus of the present invention, hot air is blown from a distance that is very close to the skewer food and all of the hot air having the rising speed generated by the gas combustion flame is directly taken into the flame capturing box. The amount of hot air heat transferred to the skewered food and dissipated without being transferred is extremely small compared to other baking methods, and the heat efficiency is very good.

  Because the heating source is not at the lower position of the skewered food, there is no dripping of the fat or sauce of the skewered food being burned on the heating source, and a dripping oil receiving tray can be installed at the lower position, so that the skewered food can be baked. At the time of completion, it is only necessary to clean the dripping oil and fat tray, and troublesome operations such as extinguishing a charcoal fire and cleaning a quartz glass tube do not occur.
