Detailed Description

The first embodiment is as follows: referring to fig. 1 and 2, the present embodiment includes an oven wall body 1 and two grill heat sources 2, the oven wall body 1 is in a rectangular parallelepiped shape, an inner cavity of the oven wall body 1 is a cavity having a rectangular horizontal cross section penetrating upper and lower surfaces, the grill heat sources 2 in a bar shape are horizontally arranged along a length direction of the oven wall body 1, the two grill heat sources 2 are symmetrically attached to two side surfaces of the inner cavity of the oven wall body 1, respectively, and the side surfaces of the inner cavity of the oven wall body 1 are mirror reflection plates 1-1. The specular reflection plate 1-1 is a high-reflectivity 8K specular stainless steel plate.

In this embodiment, the electric heating barbecue heat source 2 is a carbon fiber far infrared quartz heating tube. The carbon fiber heating body is a pure black body material, the electric heat conversion efficiency is high and generally can reach 95%, the energy mainly comprises far infrared rays, the visible light is very little, the wavelength of the far infrared rays emitted by the carbon fiber heating body is 8-14 microns (micrometers), and the carbon fiber heating body accounts for more than 70% of the total energy. The far infrared ray has strong penetrability and heat radiation power. Because the far infrared ray is close to the vibration frequency of the molecules of the cells of the living body, the barbecue food, especially the meat food, is easy to absorb the energy of the far infrared ray wave, and generates the carbon atom resonance effect in the process of transferring the heat energy of the carbohydrates of the organism, so that the cells of the organism are in the highest vibration energy level, and the heat energy can be transferred to the deep layer of the meat food because the cell resonance generates the heat effect, and the far infrared ray can directly radiate and penetrate the meat food to the depth of 20-30mm in the barbecue process. The carbon fiber far infrared quartz heating pipe has the health care functions of energy saving, environmental protection and health promotion.

In addition, the carbon fiber far infrared quartz heating has stable electrical performance: the power is stable, no instant impact current exists when the switch is turned on and off, and the heating temperature rise is extremely fast. The temperature can be adjusted freely according to different barbecue temperatures. The electric-heating conversion efficiency is as high as 95%, and the energy is saved by more than 30% compared with the common electric heating tube.

The carbon fiber far infrared quartz heating pipe is packaged by a high-purity dehydroxylation quartz glass pipe, the thermal expansion coefficient is extremely small, and the glass pipe cannot crack when meeting water of 20 ℃ in a heating state. The surface temperature of the glass tube is 500-700 ℃ during baking.

The second embodiment is as follows: this embodiment will be described in detail with reference to fig. 1 and 2. This embodiment is further explained and defined on the basis of the first embodiment. In this embodiment, the cross-sectional shape of the side surface of the inner cavity of the oven wall body 1 is a "spoon" shape having a smaller radius of curvature downward, so that the far infrared light emitted from the grill heat source 2 is converged at the upper opening of the inner cavity of the oven wall body 1 by the emission of the specular reflection plate 1-1.

With the arrangement, as shown in fig. 2, a plurality of virtual heating element mirror images 2-1 are formed behind the spoon-shaped plate surface, and the plurality of heating element mirror images form an envelope irradiation phenomenon on the upper opening of the inner cavity of the furnace wall body 1. At the upper opening of the inner cavity of the oven wall body 1, not only the far infrared ray 4 directly emitted by the barbecue heat source 2 but also the reflected far infrared ray 5 reflected to the upper opening are heated and barbecued by utilizing the principles of reflection, refraction and focusing convergence, thus improving the temperature and the thermal efficiency. The reflecting plate is made of high-reflectivity 8K mirror surface stainless steel, is bent to form a multi-section fold line or consists of multi-section curves with different curvatures, and can uniformly reflect and converge infrared heat energy generated by the heating element to a barbecue area to the maximum extent, reduce the internal temperature of the oven body and effectively improve the heat energy utilization rate of equipment.

The third concrete implementation mode: this embodiment is further described and defined on the basis of the first embodiment. See fig. 1 and 2. It also comprises an oil receiving disc 3, and the oil receiving disc 3 is filled at the lower part of the inner cavity of the furnace wall body 1.

So set up, the oven when using, oil and the entering of mince etc. that food such as kebab or roast meat went up to flow down connect food tray 3 in, avoid the polluted environment.

The fourth concrete implementation mode: this embodiment is further explained and defined on the basis of the first embodiment. The barbecue grill further comprises an oil baffle plate 6, wherein the oil baffle plate 6 is arranged on the upper part of the side surface of the inner cavity of the grill wall body 1 and is shielded above the barbecue heat source 2.

So arranged, the oil baffle 6 prevents oil droplets from splashing and falling onto the heating element when seasoning is scattered.

The fifth concrete implementation mode is as follows: this is explained in detail with reference to fig. 2. This embodiment is further explained and defined on the basis of the first embodiment. The furnace wall body is characterized by further comprising a shell 7, wherein the shell 7 is wrapped on the outer surface of the furnace wall body 1 and forms an annular space with the outer surface of the furnace wall body 1, a plurality of air inlets 7-1 are formed in the lower edge of the shell 7, and a plurality of air outlets 7-2 are formed in the upper edge of the shell 7.

So set up, air convection chimney effect has been formed, namely: a certain distance is reserved between the outer shell 7 and the outer surface of the furnace wall body 1, no additional pump action is needed, under the chimney effect, cold air is sucked from the air inlet hole 7-1 of the furnace bottom, flows through the interlayer of the inner plate and the outer plate, takes away heat conducted by the reflecting plate, and is drawn out from the upper edge of the outer shell 7 through a plurality of exhaust holes 7-2. The temperature of the shell 7 is effectively reduced, the temperature of the vertical surface of the shell 7 is between 48 and 72 ℃ (the temperature is slightly different along with the temperature of the use environment), and the scald can not be caused when the hand touches the shell. The air interlayer reduces the conduction of heat to the oven body shell in the area near the barbecue. The reason is that the thermal conductivity of air is small, and the heat energy transferred to the shell by the air flowing in the interlayer is also low.

The utility model discloses broken through traditional equipment shell cooling and taken insulation material thermal-insulated thinking, it is lower to utilize air coefficient of heat conductivity completely, utilizes the convection technology simultaneously, has reached ideal shell cooling effect.
