Description

Technical Field

[0001] The invention relates to an integrated stove with intelligent flow diversion and a flow diversion control method thereof. Background Art

[0002] Integrated stoves integrate multiple functions such as range hoods, gas stoves, disinfection cabinets, storage cabinets, etc., replacing the traditional three-piece kitchen set. It not only saves space, but also has a first-class range hood extraction effect, and is energy-saving and environmentally friendly. The traditional back duct structure, now the integrated stove has an innovation of placing the fan downward, which can increase the vertical space and volume;

[0003] The negative pressure box can form a negative pressure area because of the built-in centrifugal fan. The fans on the market now have single and double air inlets. The double air inlet has a higher air volume than the single air inlet and has a better effect. When the wind reaches the negative pressure box, it will enter from the upper and lower ends of the fan, but because there is a 90° angle between the air duct and the fan, it will cause great losses and generate a lot of noise. Summary of the invention

[0008] The guide vane grid includes an outer frame, an upper guide vane, a lower guide vane and a positioning pin; the outer frame is an annular rectangular frame, which is arranged to be hollow inside, and the external material is arranged to be a magnetic material; the upper guide vane and the lower guide vane are arc-shaped blades, and rotating shafts are arranged at both ends of the guide vane to connect with the outer frame; the positioning pin is in the shape of an elongated ring, and the positioning pin is fixed to the outer frame.

[0009] Furthermore, the width of the fixing plate is 8-10 mm; the diameter of the positioning hole is consistent with the diameter of the positioning pin, and the diameter is 2-4 mm.

[0010] Furthermore, the guide vane is provided with guide vanes, and the guide vanes can rotate up and down.
