[0001] This utility model relates to the field of heating equipment, specifically an electric oven. Background Technology

[0002] Electric ovens are devices used to bake various foods. They heat food through heating elements. During the heating process, oil, water, and residue on the surface of the food fall onto the heating elements below, producing fumes. The heating elements are inconvenient to clean. Therefore, there is a need to develop an electric oven that produces less fumes and whose heating elements do not require cleaning. Utility Model Content

[0003] To address some problems existing in current electric ovens, this utility model provides a smokeless, low-smoke, low-oil, and flameless electric oven, comprising an oven body:

[0004] The upper part of the furnace body is equipped with multiple heating tubes;

[0005] A metal cover is placed above the heating element, and the width of the metal cover is greater than the width of the heating element;

[0006] The food container is positioned above the metal cover;

[0007] The furnace body is equipped with a temperature controller and a temperature control module;

[0008] The furnace body is equipped with a power socket or power plug.

[0009] Furthermore, the lower end of the heating tube is provided with an oil collection box, which can be pulled out from one side of the furnace body.

[0010] Furthermore, the metal cover is fixed together with the fixed frame.

[0011] Furthermore, the lower end of the metal cover has an opening with a cross-sectional shape that is either arc-shaped or inverted V-shaped.

[0012] Furthermore, handles are provided on both sides of the furnace body along its length.

[0013] Furthermore, a wiring box is provided at one corner of the bottom of the furnace body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, this embodiment provides an electric oven, including an oven body 4. The upper end of the oven body 4 is provided with multiple heating tubes 1. The oven body 4 is a cubic frame structure with an opening at the bottom. The multiple heating tubes 1 are arranged side by side at equal intervals and are connected in parallel. The heating tubes 1 are provided with terminals at both ends and are connected to a power cord through terminals 13. In this embodiment, the heating tubes 1 are selected as carbon fiber quartz electric heating tubes, resistance metal electric heating tubes, or quartz light wave tubes, with a diameter of 10 mm, but not limited to a diameter of 10 mm.

[0026] A metal cover 3 is positioned above the heating tube 1. The width of the metal cover 3 is greater than the width (diameter) of the heating tube 1. Figure 5 As shown, the metal cover 3 is lower than its top on both sides in the longitudinal direction. The function of the metal cover 3 is to prevent the oil and water dripping from above from dripping onto the heating tube 1.

[0027] Food carrier 2 is positioned above metal cover 3; food carrier 2 is rectangular in shape and slightly longer than heating tube 1. Food carrier 2 is either a grill rack or a baking rack, and can be selected for different usage needs.

[0028] The furnace body 4 is equipped with a temperature controller 9 and a temperature control module. The temperature control module is connected to the neutral wire and the live wire. The temperature controller 9 controls the switch and the fire level to achieve different temperature changes. In this embodiment, the temperature controller 9 is set on one side of the furnace body 4 along the length direction. The temperature controller 9 with physical buttons is selected to facilitate the adjustment of the temperature of the heating tube 1.

[0029] The furnace body has power sockets 10 on its four side walls. Power sockets 10 can be replaced with corded power plugs.

[0030] The power connection method of the entire electric oven is as follows: multiple heating tubes 1 are connected in parallel, and the two sides are connected to the busbar respectively. One side is connected to the neutral wire, and the other side is connected to the live wire. The neutral wire and the live wire are connected to the power socket 10, and the temperature controller 9 and the temperature control module are connected to the neutral wire and the live wire.

[0031] In another embodiment of this application, an oil collection box 6 is provided at the lower end of the heating tube 1. Water can be added to the oil collection box 6 in advance to cool and dilute the fallen grease, water and food residue, and avoid open flame and oil fumes. The oil collection box 6 can be pulled out from one side of the furnace body 4.

[0032] In another embodiment of this application, the metal cover 3 is fixed together with the fixed frame 11, so that multiple metal covers 3 and the fixed frame 11 form an integral structure, making it convenient to remove the metal cover 3 and the fixed frame 11 for cleaning. The fixed frame 11 is provided with positioning holes on both sides, and the metal cover 3 and the fixed frame 11 are installed on the positioning columns on both sides of the furnace body 4 to limit the position of the metal cover 3.

[0033] In another embodiment of this application, the lower end of the metal cover 3 is open, and its cross-sectional shape is an arc or an inverted V. This embodiment prefers an inverted V shape, and the apex of the inverted V is a right angle, which makes it easier to process and install and fix. The oil, water, and residues attached to or generated by the grilling of the food placed on the grill rack or grill on the upper side of the metal cover 3 fall onto the surface of the metal cover 3 due to gravity, and then quickly drip down along both sides of the metal cover 3 into the oil collection box 6 below that collects oil, water, and residues. They will not come into contact with the heating tube 1, so no oil smoke will be generated. Water (with a maximum water temperature of 100 degrees Celsius, below the smoke point) is added to the oil collection box 6 in advance. The oil, water, and residues falling into the box are below the smoke point, thereby maximizing the smokeless or low-smoke effect.

[0034] In another embodiment of this application, handles 12 are provided on both sides of the oven body 4 along its length to facilitate moving the entire electric oven.

[0035] In another embodiment of this application, a wiring box 7 is provided at one corner of the bottom of the furnace body 4. The temperature at the bottom corner is the lowest, and it will hardly damage the wires. The wiring box 7 is convenient for wiring, and the opening at the bottom of the furnace body 4 makes it easy to install and remove the wiring box 7.

[0036] In another embodiment of this application, the bottom four corners of the furnace body 4 are provided with pads 8, which can serve as support and anti-slip.

[0037] In another embodiment of this application, the heating tube 1 is partially coated with a reflective layer, that is, a reflective layer is coated on its lower half surface. The reflective layer mainly serves to direct heat radiation, and its function is equivalent to a reflector, reducing downward heat radiation and reducing the temperature rise of the liquid in the oil collection box 6 by the heating tube 1, while improving the heating effect on the food on the food carrier 2. The half-surface coating can be gold-plated or white-plated. The reflective efficiency of gold-plated and white-plated is basically equal to or even much higher than that of mirror stainless steel and various aluminum reflectors. Gold-plated or white-plated can be selected according to actual needs.

[0038] In another embodiment of this application, a temperature control module and a cooling fan 5 are connected to the power cord. A temperature control controller 9 is connected to the temperature control module. In this embodiment, a commercially available silicon controlled rectifier (SCR) voltage regulator, manufactured by Shenzhen Global Easy Technology Co., Ltd., is selected. It includes a temperature control controller 9 and a temperature control module, with a maximum supported power of 6000W and a voltage of 220V or 380V. After power is applied, the temperature control controller 9 controls the switch and the heat level. The cooling fan 5 is installed on the side wall of the furnace body 4, or heat dissipation holes corresponding to the cooling fan 5 are machined on the upper side wall of the furnace body 4.

[0039] In another embodiment of this application, the metal cover 3 has a width of 22-26 mm and a height of 8-11 mm; the food carrier 2 is 2-4 mm away from the top of the metal cover 3, and the bottom of the metal cover 3 is 4-6 mm away from the top of the heating tube 1.
