Description
Technical field
The utility model belongs to household electrical appliance technical field, is specifically related to a kind of baking box heated air circulation fan.
Background technique
Heated air circulation fan and traditional fan of baking box are different, traditional fan is dried forward, and the heated air circulation fan of baking box needs the both sides of hot blast toward fan to carry, as shown in Figure 1, in the hot air circulating system of baking box, circulating fan needs the heat by burner produces to carry toward the both sides of fan, is then guided the path of heated air circulation by wind deflector, reaches the object improving the thermal efficiency.The fan blade of conventional fan is generally provided with certain radian, to reach the object of blowing forward, because conventional fan is air-supply before fan, cannot meet the air-supply requirement of heated air circulation.
Model utility content
For overcoming the deficiencies in the prior art, the utility model devises a kind of baking box heated air circulation fan, this baking box is centrifugal type fan with heated air circulation fan, the fan blade of fan is arranged to right angle tabular, an air channel is outwardly formed between adjacent two fan blades, after hot blast enters from intake opening, through centrifugal rotation from outwardly air channel output, thus reach the effect of being carried toward fan both sides by hot blast.
For realizing technique scheme, the utility model provides a kind of baking box heated air circulation fan, comprising:
Wind wheel, described wind wheel is provided with multiple intake opening, and described multiple intake opening is around the central axis circumference array of wind wheel;
Be fixed on wind wheel side and the multiple fan blades consistent with intake opening quantity, described multiple fan blade is around the central axis circumference array of wind wheel, and multiple fan blade and multiple intake opening are staggered, the rectangular tabular of described fan blade, forms an air channel between adjacent two fan blades;
Axle sleeve, described axle sleeve is arranged on the center of wind wheel, and wind wheel is connected with motor by axle sleeve.
In technique scheme, motor drives wind wheel and fan blade to rotate, after hot blast enters from intake opening, carry toward both sides via the air channel formed between adjacent two fan blades, due to the rectangular tabular of fan blade, so most hot blast can not be carried forward, but centrifugally along the direction in air channel to throw away, multiple fan blade and multiple intake opening are staggered, and make the conveying of centrifugal hot blast more even.
Preferably, described fan blade is provided with 45 ° of angles of wedge near sleeve end, the angle of wedge the intensity that can strengthen centrifugal hot blast is set.
Preferably, described fan blade is provided with a bending section near one end of wind wheel, and described bending section is fixed by screws on wind wheel, and fan blade is fixed on wind wheel by bending section.
Preferably, described fan blade is right angle corrosion resistant plate or right angle plastic board.
Preferably, the quantity of described fan blade is eight, and the center of circle angle between adjacent two fan blades is 45 °.
Preferably, described intake opening is ellipse hole.
The beneficial effect of a kind of baking box heated air circulation fan that the utility model provides is: 1) this heated air circulation fan can provide centrifugal wind-force towards fan surrounding to greatest extent; 2) fan blade and intake opening are staggered, and make the conveying of centrifugal hot blast more even.

In figure: 1, wind wheel; 2, fan blade; 3, axle sleeve; 4, bending section; 5, intake opening; 21, the angle of wedge.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, carry out clear, complete description to the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Related domain ordinary person, not making the every other embodiment obtained under creative work prerequisite, all belongs to protection domain of the present utility model.
Embodiment: a kind of baking box heated air circulation fan.
Shown in seeing figures.1.and.2, a kind of baking box heated air circulation fan, comprising: wind wheel 1, and described wind wheel 1 is provided with multiple intake opening 5, and described multiple intake opening 5 is around the central axis circumference array of wind wheel 1; Be fixed on wind wheel 1 side and the multiple fan blades 2 consistent with intake opening 5 quantity, described multiple fan blade 2 is around the central axis circumference array of wind wheel 1, multiple fan blade 2 is staggered with multiple intake opening 5, and described fan blade 2 is tabular at right angles, forms an air channel between adjacent two fan blades 2; Axle sleeve 3, described axle sleeve 3 is arranged on the center of wind wheel 1, and wind wheel 1 is connected with motor by axle sleeve 3.
In technique scheme, motor drives wind wheel 1 and fan blade 2 to rotate, after hot blast enters from intake opening 5, carry toward both sides via the air channel formed between adjacent two fan blades 2, due to fan blade 2 at right angles tabular, so most hot blast can not be carried forward, but centrifugally along the direction in air channel to throw away, multiple fan blade 2 is staggered with multiple intake opening 5, makes the conveying of centrifugal hot blast more even.
With reference to shown in Fig. 1, described fan blade 2 is provided with 45 ° of angles of wedge 21 near axle sleeve 3 end, the angle of wedge 21 the intensity that can strengthen centrifugal hot blast is set.
With reference to shown in Fig. 1, described fan blade 2 is provided with a bending section 4 near one end of wind wheel 1, and described bending section 4 is fixed by screws on wind wheel 1, and fan blade 2 is fixed on wind wheel 1 by bending section 4.
In the present embodiment, described fan blade is right angle corrosion resistant plate.
In the present embodiment, the quantity of described fan blade 2 is eight, and the center of circle angle between adjacent two fan blades 2 is 45 °, and experiment proves that fan blade 2 is set to eight, center of circle angle between adjacent two fan blades 2 is when being 45 °, and the centrifugal hot blast that circulating fan provides is the most even.
In the present embodiment, described intake opening 5 is ellipse hole.
The above is preferred embodiment of the present utility model; but the utility model should not be limited to the content disclosed in this embodiment and accompanying drawing; the equivalence completed under not departing from spirit disclosed in the utility model so every or amendment, all fall into the scope of the utility model protection.
