Description
Technical field
The utility model relates to the technical fields of household electrical appliances, are dissipated more particularly, to a kind of oven using the circulation of double wind wheel
Hot systems.
Background technique
In the prior art, the door body heat dissipation of electric (combustion gas) oven is using double air ducts endless form, with cross flow fan wind wheel
Rotation generate hot and cold air circulation, to reduce door body temperature rise and electric appliance internal heat, but this mode is confined to through-flow wind
The design feature of machine itself wind wheel, the negative pressure of generation is less than normal, and the cold air stream that door body lower end enters is smaller, so cooling effect is not
Obviously.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, provides a kind of oven and uses double wind wheel
Cycle cooling system, which can be improved oven door heat dissipation effect.
In order to solve the above technical problems, the technical solution of the utility model is as follows: a kind of oven uses the circulation of double wind wheel
Cooling system, the cooling system are arranged along oven door and cavity periphery, and cycle cooling system specifically includes: air duct, the
One air inlet, total air outlet, driving device and fan blade；The air duct includes door body air duct, the first air duct and the second air duct, described
First air duct, the second air duct are stacked and are interconnected, and first air duct is connected to door body air duct, door body air duct edge

In road, driving device is able to drive fan blade and rotates so that air-flow is arranged along duct flows after air inlet entrance and from total air outlet
Out.
In the program, since oven door heat dissipation wind channel is narrow, cause door body radiating rate slow, heat dissipation effect is bad, and
Fan blade is added in ducting system and matching for driving device postpones, fan blade rotation can form negative pressure in air duct, to promote
The flowing of air duct interior air-flow, so as to promote cool exterior air to be rapidly introduced into inside air duct and be quickly discharged outside air duct, by
This enables oven door heat to be quickly carried over, so that the efficiency of the heat discharge of oven door part is substantially increased,
Improve safety and user experience.
Further, the fan blade includes the first fan blade and the second fan blade, and the coaxial driving that is fixedly mounted on of the two fills
On the output shaft set, first air duct and the second air duct connectivity part are communication port, and first fan blade is arranged first
In air duct, second fan blade is arranged in the second air duct, and the output shaft of the driving device passes through communication port.Due to
One air duct and the second air duct are stacked, thus, two fan blades are arranged respectively can be further in the first air duct and the second air duct
Promote the circulation of air-flow, it is preferred that the air inlet in the first air duct and the air outlet in the second air duct are in the same side, in such case
Under, it can more embody the advantage of double fan blade settings.

Mouth direction rises without being to continue with, and blade damper can effectively change the wind direction for the air-flow being drawn into, it is preferred that blade and gear
Plate is arranged in a mutually vertical manner, and is lateral flow so that air-flow turns under baffle effect after rising and oven is discharged by total air outlet
It is external.Air channel is not limited to be horizontally disposed with, and can also have certain angle according to oven shape, corresponding, blade damper with
Angle between blade changes according to air duct and total direction of air outlet, so that air-flow can smoothly turn to discharge, preferably
Baffle and interlobate angle can for 30 to 90 degree.
In addition to door body be easy it is hot other than, the oven body portion of oven is also to be easy to be heated hot, and internal component
It is easy to be influenced by high temperature, thus, further, the air duct further includes internal air duct, and the internal air duct is outside oven cavity
The roasting box house setting in week, the internal air duct includes the second air inlet and is connected to by the second air inlet with outside, and institute
Stating the first air duct includes the second communication port, and internal air duct is connected to by the second communication port with the first air duct, enables air-flow edge
Cavity periphery enter the first air duct and eventually by total air outlet be discharged.The heat dissipation of entire oven is enabled to more to fill in this way
Point, it is preferred that internal air duct can pass through critical internal component position, to promote the heat dissipation of internal component.It is excellent
Choosing, the air inlet setting in internal air duct is arranged at the top of oven in oven bottom, the first air duct and the second air duct, the electricity of oven
Device element is located in top and internally positioned air duct, cold air external in this way enter internal air duct from bottom after along entire oven body
It moves and is discharged to outside oven after electric elements, so that the better heat-radiation effect of entire oven.
Further, first air inlet is located at oven door bottom, and first air duct and the second air duct are located at
At the top of oven door.In this way, external cold air enters the at the top of oven door after passing into oven door really from oven door bottom
One air duct enters back into the second air duct and is discharged outside oven.
Further, the first air duct stated is located at the second air duct bottom.Such design is conducive to save the space in air duct,
To effectively control the size of oven.
Further, first fan blade is made of metal and/or plastics, second fan blade by metal and/or
Plastics are made.
Compared with prior art, beneficial effect is:
(1) fan blade is set in air duct, promotes the heat dissipation of oven door；
(2) be arranged the first air duct, the second air duct and be correspondingly arranged the first fan blade, the second fan blade further promotes the stream of air-flow
It is dynamic；
