Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of warming device of Electric heat oven in prior art.
As shown in Figure 1, the device of warming of existing Electric heat oven comprises: natural wind import 1, waste gas outlet 4 and heater 6.When it is cold, because the temperature of baking oven outside is very low, the natural wind that enters Electric heat oven only has 0 degree to 5 degree left and right, cold wind needs to heat by the heater 6 baking oven unit after natural wind import 1 is come in, at this moment baking oven heating unit needs all work, energy consuming ratio is larger, even like this, can not make the wind that enters Electric heat oven reach rapidly needed temperature, greatly reduce production efficiency, due to the full-load operation of baking oven heating unit, also can be reduced the service life of baking oven heating unit simultaneously.
Therefore there is the defects such as power consumption is large, production efficiency is low, service life is low in the device of warming of Electric heat oven of the prior art.
Fig. 2 is the structural representation of the utility model embodiment.
As shown in Figure 2, the preferred a kind of Electric heat oven of the utility model warm device, it comprises: natural wind import 1, natural wind outlet 2, exhaust gas inlet 3, waste gas outlet 4, heat-transfer device 5 and heater 6; Described natural wind import 1 and exhaust gas inlet 3 are arranged on one end of described heat-transfer device 5, described natural wind outlet 2 and waste gas outlet 4 are arranged on the other end of described heat-transfer device 5, natural wind import 1, exhaust gas inlet 3 communicate with natural wind outlet 2, waste gas outlet 4 by heat-transfer device 5 respectively, and described heater 6 is communicated with natural wind outlet 2 with exhaust gas inlet 3.
