A kind of electric oven
Technical field
The utility model relates to a kind of electric oven, belongs to the improvement technology of electric oven.
Background technology
Existing electric oven structure as shown in Figure 1, comprise the bottom deck assembly that constitutes the heating cavity space, back board component 2, the left plate assembly, right plate assembly 4, top board 5 and front door assembly 6, wherein the top of top board 5 is equiped with outer cover 7, heating tube 8 places the below of top board, its two ends are installed on left plate and the right plate, existing electric oven is to avoid the temperature of outer cover upper surface too high, outer cover and top board need be kept somewhere bigger spatial joint clearance, thereby the miniaturization that makes baking box becomes difficult, the oven heat cavity space also can reduce, and when picking and placeing food, run into heating tube easily, pick and place food also be careful careful, in addition, usually food is placed on the base plate medium position during heating, therefore heating tube is comprehensive heat radiation in cavity, is difficult to concentrate on central heating region, and it is on the low side to roast the efficiency of heating surface.
The utility model content
The purpose of this utility model is to address the above problem and a kind of type body of providing is little, and efficiency of heating surface height can effectively reduce the temperature rise of outer cover in the heat food process, Qianmen and back board component, and conveniently picks and places the electric oven of food.
The technical solution of the utility model is: a kind of electric oven, comprise the bottom deck assembly, back board component, left plate assembly, right plate assembly, top board and the front door assembly that constitute the heating cavity space, wherein the top of top board is equiped with outer cover, heating tube places the below of top board, its two ends are installed on left plate assembly and the right plate assembly, it is characterized in that described top board comprises back catadioptric plate, flat-top reflecting plate and preceding catadioptric plate, to cavity, heating tube placed in the cavity in three reflecting plates were connected to form.
The front side of catadioptric plate is provided with the folding top board before above-mentioned, on roll over top board most significant end be connected above the front door assembly.
The position of corresponding back catadioptric plate is provided with some louvres on the board component of above-mentioned back.
The angle α of above-mentioned back catadioptric plate and flat-top reflecting plate is 90~150 °.
The angle β of above-mentioned front side reflecting part and flat-top reflecting part is 90~150 °.
Distance H between above-mentioned heat-generating pipe and the flat-top reflecting plate is 5~15mm.
The utility model since adopt with heating tube place by back catadioptric plate, flat-top reflecting plate, and before the catadioptric plate be connected to form in structure in cavity, the more concentrated middle position that reflexes to heating cavity of the heat of heat-generating pipe, therefore, improved the efficiency of heating surface of food greatly, avoid the heat of heating tube directly to be radiated on front door assembly and the back board component simultaneously, can effectively reduce the temperature rise of outer cover in the heat food process, Qianmen and back board component; In addition, roll over top board because the front side of preceding catadioptric plate is provided with, therefore, it is very convenient to pick and place food, and can avoid touching heating tube; The 3rd position owing to corresponding back catadioptric plate on the board component of back is provided with some louvres, thermal current between top board and the outer cover can be discharged in the air by louvre, greatly reduce the temperature of outer cover, so do not need between outer cover and the top board to keep somewhere bigger spatial joint clearance, make the baking box miniaturization.

Fig. 2 is the partial schematic diagram of the utility model electric oven.
The specific embodiment
The utility model is described in further detail to reach embodiment with reference to the accompanying drawings.
As shown in Figure 2, the utility model electric oven, comprise the bottom deck assembly (not shown), back board component 2, left plate assembly (not shown), right plate assembly 4, top board 5 and the front door assembly 6 that constitute the heating cavity space, wherein the top of top board 5 is equiped with outer cover 7, heating tube 8 places the below of top board, its two ends are installed on left plate assembly and the right plate assembly, top board 5 comprises back catadioptric plate 51, flat-top reflecting plate 52 and preceding catadioptric plate 53, to cavity, heating tube 8 placed in the cavity in three reflecting plates were connected to form.
In the present embodiment, for conveniently picking and placeing food, above-mentioned before the front side of catadioptric plate 53 be provided with folding top board 54, on roll over top board 54 most significant end be connected above the front door assembly.For the thermal current between top board and the outer cover is discharged in the air, reduce the temperature of outer cover, the position of corresponding back catadioptric plate 51 is provided with some louvres 21 on the board component 2 of above-mentioned back.
In the present embodiment, for the heat that makes heat-generating pipe is concentrated the middle position that reflexes to heating cavity to greatest extent, improve the efficiency of heating surface of food, above-mentioned back catadioptric plate 51 is 90~150 ° with the angle α of flat-top reflecting plate 52, above-mentioned front side reflecting part 53 is 90~150 ° with the angle β of reflecting part 51, top, and the distance H between above-mentioned heat-generating pipe 8 and the flat-top reflecting plate 52 is 5~15mm.
