Description

Technical Field

[0001] The utility model relates to the technical field of electric barbecue grills. Background Art

[0002] Currently, in the prior art, the Chinese utility model patent number is ZL202222145714.4, and the name is: An Electric Barbecue Grill. The electric barbecue grill includes a furnace body with a heating cavity and a grill net placed above the heating cavity. An electric heating unit and an oil drip tray are arranged in the heating cavity. The oil drip tray is arranged at an interval from the furnace body. A plurality of heat insulation brackets are installed on the peripheral side wall of the furnace body, and the oil drip tray is clamped on the plurality of heat insulation brackets; Two grill nets are stacked up and down. Both grill nets include an annular frame, a plurality of cross bars arranged in parallel in sequence, and a plurality of pins installed on the annular frame. The two ends of the cross bar are respectively fixed on both sides of the annular frame, and the cross bars between the two grill nets are arranged in a staggered manner; A kidney-shaped groove is opened on the oil drip tray, and a jack is opened on the heat insulation bracket. The pin passes through the kidney-shaped groove and is inserted into the jack of the heat insulation bracket; The electric heating unit includes an electric heating pipe, and the mouth of the oil drip tray is higher than the spatial position of the electric heating pipe. The problems are as follows: The electric heating pipe is horizontally arranged in the heating cavity below the grill net. During the barbecue process, small foods, oils and fats, seasonings, etc. falling on the high-temperature electric heating pipe will generate a large amount of odor and smoke, polluting the air, and the close contact between the electric heating pipe and the barbecue skewers will easily cause the food to be burned; At the same time, the surface temperature of the furnace body is too high and is easy to scald people. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an electric barbecue grill that can accelerate the temperature rise, so as to solve the problems raised in the above background art. While realizing smokeless barbecue of food, this electric barbecue grill also accelerates the temperature rise speed of the barbecue cavity, effectively improving the barbecue efficiency; And the temperature of the furnace shell surface is relatively low and is not easy to scald people.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An electric barbecue grill that can accelerate the temperature rise, which includes a furnace body with a barbecue cavity, a grill, an oil drip tray, an electric heating pipe, and a control device. The grill covers the opening of the furnace body. The oil drip tray is arranged in the barbecue cavity at the bottom of the furnace body. Two electric heating pipes are symmetrically arranged in the front and rear side walls of the barbecue cavity respectively, and the electric heating pipes emit heat and radiate towards the barbecue cavity and the grill.

[0006] Specifically, the furnace body includes a furnace shell, an inner box body, and a connecting seat that penetrate up and down. Two connecting seats are respectively fixedly connected to the left and right sides of the inner box body. The inner box body and the connecting seat are placed inside the cavity of the furnace shell and connected to form the furnace body. There is a drop between the upper opening of the inner box body and the upper opening of the furnace shell. The height of the upper opening of the inner box body is lower than that of the upper opening of the furnace shell. The grill is placed into the furnace body from the upper opening of the furnace shell and covers the upper opening of the inner box body, preventing people from being scalded by the high-temperature grill.

[0007] The inner box body includes a front side plate, a rear side plate, a left side plate, a right side plate, and a bottom plate. The front side plate, the rear side plate, the left side plate, the right side plate, and the bottom plate enclose a roasting cavity. A plurality of horizontally arranged grid holes are provided along the length direction of the front and rear side plates. The electric heating tube is arranged at the rear side of the grid holes, and the far-infrared rays emitted by the electric heating tube pass through the grid holes and radiate towards the roasting cavity and the grill.

[0008] Furthermore, it further includes a reflective member. The reflective member is arranged behind the grid holes and is hermetically connected to the front side plate or the rear side plate. The reflective member semi-encloses the cylindrical electric heating tube. Part of the far-infrared heat emitted by the electric heating tube is reflected and concentrated by the reflective member and then passes through the grid holes, accelerating the temperature rise of the inner box body.

[0009] The reflective member is made by bending a stainless steel thin sheet with a bright surface into an integral shape.

[0010] The electric heating tube is a carbon fiber electric heating tube.

[0011] Even further, it further includes a heat insulation plate. The heat insulation plate is arranged behind the reflective member. The bottom plate located below the front side plate or the rear side plate is respectively provided with a first air inlet hole and a second air inlet hole in parallel. The heat insulation plate is erected on the bottom plate between the first air inlet hole and the second air inlet hole. Air enters the inner box body from the first air inlet hole, absorbs the heat on the reflective member, and diffuses into the inner box body to form a heat convection. Under the combination of heat radiation and heat convection, the heat generated by the electric heating tube enables the temperature on the roasting cavity and the grill to quickly reach the barbecue temperature.

[0012] Even further, there is a gap between the heat insulation plate and the outer wall of the furnace shell. Air enters from the first air inlet hole, flows upward along the gap, and then is discharged from the top of the furnace body, thereby forming a heat insulation air curtain, preventing the surface temperature of the furnace shell from being too high and avoiding the possibility of scalding people.

[0013] For an electric barbecue grill with an accelerated temperature rise of the present utility model, since the electric heating tubes are hidden behind the grid holes on the front and rear side plates of the roasting cavity, the original structure with the electric heating tubes located below the grill is cancelled, preventing grease, food ingredients, seasonings, etc. from falling onto the electric heating tubes from the grill and generating fumes, achieving smokeless barbecue. At the same time, with the cooperation of the reflective member and heat convection, the temperature rise on the roasting cavity and the grill is accelerated. The double-layer structure of the furnace body prevents the surface temperature of the furnace shell from being too high, avoiding the potential hazard of scalding people and making the use safer.
