Description

A new type of electric heating grill

Technical field

The invention relates to an electric heating grill, in particular to a novel electric heating grill.

Background technique

The electric heating grilling furnace uses the radiant heat generated when the heating pipe works to achieve the purpose of heating the food. Compared with the conventional carbon-baked oven, it is more and more widely used in people because it does not require firing, uniform heating, and simple use. In everyday life.

Electric heating grills, there are many ways to set the heating pipes, the common settings are below the food in the center of the furnace, but the grease is easy to drip on the heating pipes. There are also disposed on the two side walls of the furnace body, and the reflector of the heating tube faces the barbecue net, the heat of the heating tube is radiated to the grilling net to heat the food thereon, and in order to undertake the dripping of the food, the heating under the grilling net The oil pan is directly arranged in the cavity, and the oil can be directly dropped on the oil pan without other spacers; the problems of this structure are as follows: 1. The heating pipe is located on both sides, and the barbecue net is close to the heat pipe. The heating effect on both sides is good, and the heat in the middle of the barbecue net is limited, which makes the food on the barbecue net unevenly heated. 2. Because the oil pan is in the heating chamber, the temperature will be higher and higher during use. The dripping grease will sinter or form soot under the action of high temperature, thus affecting the consumer experience; 3. The distance between the two sides of the furnace body should not be too wide, otherwise the food located in the middle area of the grilling net cannot obtain sufficient heat energy. It restricts the shape and structure design of the grill and reduces the effective working area of the grill.

Detailed ways

Referring to FIG. 1 to FIG. 3, a novel electric heating grilling furnace comprises a square furnace body 1 and a heating pipe 2 disposed on both sides of the furnace body. The lower part of the furnace body is provided with an oil leakage groove 8 and an oil receiving plate 6, and the upper part of the furnace body 1 There is a barbecue area 4, and a heating reflector 2 is arranged outside the heating tube 2 to surround the heating tube 2 from the back, so that the heat radiated from the back of the heating tube can enter the reflective heating chamber 11 through the reflector 3; The inverted V-shaped reflector 51 can reflect the heat energy of the heat pipe 2 on both sides of the furnace body to the food in the barbecue area, so that the food in the middle of the barbecue area can also obtain sufficient heat energy, so that the food on the barbecue area is more evenly heated. The height of the V-shaped reflector 51 is higher than that of the heat-generating tube 2, so that the radiant heat of the heat-generating tube can be more reflected to the upper working surface to avoid heat loss; the oil pan 6 is located outside the heat-reflecting chamber 11 The inverted V-shaped reflector 51 and the bottom wall of the heating chamber are isolated to prevent the recovered grease from generating sintering or soot at a high temperature.

In the above structure, the left and right sides of the inverted V-shaped reflecting plate 51 may be formed by a straight plate to form an inverted V-shape, or a concave curved plate may be used to form an inverted V-shape, and the radiant heat of the heat-generating tube 2 may be reflected as long as it is inclined. To the middle of the barbecue area, therefore, although the middle of the barbecue area is far from the heat pipes on both sides, because the heat energy on both sides is concentrated, the food on it can also obtain sufficient heat energy.

Preferably, the heat pipe 2 and the curved reflector 3 are located outside the grease dripping area of the grilling area 4, and the cover area 9 is provided on both sides of the grilling area 4 to shield it. In this embodiment, the projection of the upper edge 31 of the curved reflector 3 in the vertical direction exceeds the lower edge 32, so that the reflecting surface can be better formed, so that the heat of the heat pipe 2 can be concentrated obliquely upward to the barbecue area 4 The work surface is not lost on the non-working surface cover 9, and it is also possible to prevent a large amount of grease from dripping on the reflector to generate soot.

The bottom of the furnace body 1 on both sides of the inverted V-shaped reflector plate 51 is further provided with a reflecting plate 7 so that the radiant heat of the heat-generating tube 2 can be reflected back to the work surface no matter where it is reached, thereby improving the heating efficiency and heat utilization rate of the entire furnace body 1. .

The boundary between the reflecting plate 7 and the inverted V-shaped reflecting plate 51 is formed at the lowest point and is provided with the oil leakage groove 8. During the operation, the grease of the food can be flown on the reflecting plate 7 or the inverted V-shaped reflecting plate 51 during the operation. The lowest point and falls into the oil pan 6 from the oil leakage groove 8. The oil pan 6 is disposed under the inverted V-shaped reflector 51, and is separated from the heating reflection chamber 11 of the furnace body 1 by the reflection plate 51 and the reflection plate 7, and the temperature does not rise as the temperature in the heating reflection chamber increases. High to avoid avoiding the production of sinter or soot at high temperatures.

In order to better achieve ventilation and heat dissipation, the inverted V-shaped reflecting plate 51, the reflecting plate 7 and the furnace body leg 10 form a ventilation cavity 12 below the furnace body 1. The temperature of the inverted V-shaped reflector 51 and the reflective plate 7 is prevented from being too high, so that no oil fumes are formed after the grease drops, and an excellent smokeless barbecue is realized, thereby further improving the user experience.

Due to the reflection of the arc-shaped reflector 2 and the inverted V-shaped emitter plate 51 at both ends, the uniform radiation heating of the left and right portions of the grilling area can be well achieved, so that the width of the furnace body can be as needed The increase does not affect the heating of the middle portion of the grilling net, thereby greatly increasing the effective working area of the grilling net and the freedom of the structure and shape design of the grill. At this time, the heating tube 2 can be set in the short of the square furnace body 1. On the side, the grill can use a shorter heating tube, which makes the product cost control and design more coordinated.

The technical solution of the present invention can also be as shown in FIG. 4, except that the circular furnace body is different from the foregoing embodiment, the other design concepts are the same; and because the circular furnace body is adopted, the inverted V in the middle of the square furnace body The reflective plate 51 needs to be replaced with a tapered reflector 52 suitable for a circular furnace body.

The novel electric heating grilling furnace of the invention has the advantages of simple structure and low cost, but can achieve an excellent barbecue effect, and the food in the barbecue area can be more uniformly heated, and at the same time, the sintering and the soot in the barbecue process can be effectively reduced, and the consumer experience is good. Can be widely used on a variety of barbecue stoves.
