Machine drives cooling fan blade rotation, and outdoor cold wind is brought into the cooling air channel of cavity, the height of cooling air channel is entered from upper cavity
Warm flue gas is discharged after mixing with cold wind from upper air outlet and lower air outlet incessantly.For being equipped with upper and lower two heating cavities
Cabinet, wherein cooling air channel increases the flow velocity of lower layer's outlet air, makes cooling effect more preferably using being specifically designed.Cooling blower
Only with one, not only save the cost, can also sufficiently send out the effect of brightness cooling blower, guarantee the wind of all directions in cooling air channel
Pressure, and bigger space is reserved to upper and lower cavities, it ensure that effective heating volume.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing:
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the utility model cabinet longitudinal sectional view；
Fig. 3 is cooling air channel schematic perspective view.
Specific embodiment
The utility model provides a kind of oven cooling structure, and described includes cabinet 1, is equipped with hollow cavity, chamber in cabinet
Body front openings simultaneously realize door body and a kind of state when the work of cavity open or close by door body, are equipped between the outer wall of cavity
Hollow cooling air channel, cooling air channel include the upper cooling air channel 31 being located at the top of cavity being sequentially communicated, point of chamber rear
Flow the lower cooling air channel 33 of air duct 32 and cavity bottom, top of the upper cooling air channel 31 before cavity, which is equipped with, to be in communication with the outside
Upper air outlet 34, lower section of the lower cooling air channel 33 before cavity is equipped with the lower air outlet 35 being in communication with the outside, described cold
But air duct 31 is externally provided with cooling blower 4, and the cold wind input terminal 41 of cooling blower 4 is connected to upper cooling air channel 31, at the top of cavity
Inner wall is equipped with the mouth being connected to cooling air channel.The cooling blower 4 is at the top of cavity close to the position of chamber rear.
The oven that the utility model can be adapted for a cavity is readily applicable to the oven of two cavitys.
As depicted in figs. 1 and 2, the cavity have up and down two, the upper cooling air channel 31 be located at upper cavity 21 top,
Shunt duct 32 is located at the rear portion of upper cavity 21, lower cooling air channel 33 is located at the bottom of upper cavity 21, the upper air outlet 34
Top before upper cavity 21, the lower air outlet 35 are located at the lower section before upper cavity 22, set on the inner wall at 21 top of upper cavity
There are the upper cavity mouth 51 being connected to upper cooling air channel 31, the cigarette that the heat radiation baking food of the heat-generating pipe B of upper cavity 21 generates
Gas rises to upper cooling air channel 31 toward upper cavity mouth 51, and the inner wall at 22 top of lower chamber is equipped with to be connected to lower cooling air channel 33
Lower chamber mouth 52, the heat-generating pipe C of lower chamber 22 heat radiation baking food generate flue gas toward lower chamber mouth 52 rise
To lower cooling air channel 33, the cooling blower 4 is mounted on 31 top of cooling air channel.
High-temperature flue gas can be generated during toasting food, guild is from upper cavity mouth on 21 high temperature flue gas of upper cavity
51 enter upper cooling air channel 31, and for upper cavity mouth 51 before cooling blower 4, the cold wind entered from cooling blower 4 has one
Divide flow forward, while being smoothly discharged from upper air outlet 34 by row forward together with the flue gas that upper cavity mouth 51 comes out.Cavity of resorption
High-temperature flue gas in body 22 also can uplink, and enter lower cooling air channel 33 from lower chamber mouth 52, and enter from cooling blower 4
Cold wind some can by distinguished and admirable air duct 32 enter lower cooling air channel 33, these cold wind will with high-temperature flue gas from it is lower go out
Air port 35 is discharged.In addition, lower chamber 22 lower part and behind also can some hot gas out of 1 lower part of cabinet and back
Uplink between outer wall, at these hot gas rows to cooling blower 4 after the blower 4 that is cooled again be pumped into, then with air-flow respectively from upper air outlet
34 and lower air outlet 35 be discharged.
As shown in figure 3, the cooling blower 4 only one, be fixed on the top of upper cavity 21 close to the position of chamber rear.
It is such that not only save the cost is set, the effect of cooling blower 4 can also be given full play to, guarantees the wind of all directions in cooling air channel
Pressure, and bigger space is reserved to upper and lower cavities, it ensure that effective heating volume.
As shown in figure 3, the upper cooling air channel 31 is narrowed from upper air outlet 34 to 32 upper lateral of shunt duct, lower cooling
