Abstract
The utility model provides a centrifugal fan dedicated for a burner of commercial kitchenware. The centrifugal fan is characterized in that an output shaft of a motor is connected with a centrifugal turbine shaft, the centrifugal turbine shaft is provided with a centrifugal turbine which is provided with an axial turbine air inlet, the centrifugal turbine is provided with two annular side plates, blades are evenly distributed on the circumference between the two annular side plates at intervals, central holes of the annular side plates are axial air inlets, the centrifugal turbine is arranged in a fan shell body which is provided with a fan shell body air inlet corresponding to the positions of the axial centrifugal turbine air inlets, the fan shell body is provided with an air outlet, and a gap between the periphery of the centrifugal turbine and the inner wall of the fan shell body gradually becomes smaller from the air outlet and along the periphery of the centrifugal turbine. The centrifugal fan is proper in air amount, high in air pressure, light in weight, balanced and stable in various elements, and capable of saving power consumed by air suction so as enable a fan to be more energy-saving.
Description
Technical field
The utility model belongs to a kind of kitchen kitchen range, relates in particular to the blower fan of a kind of kitchen burning machine.
Background technique
The blower that existing kitchen kitchen range are used has the characteristics such as power is large, air quantity is large, volume and weight is bigger than normal, poor sealing.With respect to the kitchen tools burning machine, power is large, the waste electricity; Air quantity is excessive, and temperature descends, and heat loss increases; The gas flame color is the inadequate purple of burning or fuel oil flame is the inadequate blueness of burning, waste fuel.
The model utility content
The utility model provides a kind of commercial kitchen tools burning machine special-purpose centrifugal fan, and its purpose solves the shortcoming that prior art exists, and makes that fan delivery is moderate, blast is high, lightweight, the indices balance and stability.
The technological scheme that its technical problem that solves the utility model adopts is:
The special-purpose centrifugal fan of commercial kitchen tools burning machine, it is characterized in that: be connected with a centrifugal vortex wheel shaft on the output shaft of a motor, be provided with a centrifugal turbine with axial centrifugal turbine intake grill on the centrifugal vortex wheel shaft, centrifugal turbine has two annular side plate, between two annular side plate, the circle spacing is evenly equipped with blade, and the center hole of annular side plate is the air inlet through hollow shaft mouth; Centrifugal turbine is placed in a Blower Housing, and Blower Housing is provided with the Blower Housing intake grill corresponding with axial centrifugal turbine intake grill position; Blower Housing has exhaust outlet, and the gap of centrifugal turbine periphery and Blower Housing inwall is reduced along the centrifugal turbine periphery gradually by exhaust outlet.
Usefulness of the present utility model is:
The utility model adopts centrifugal fan on the blower of kitchen tools burning machine, centrifugal fan mainly leans on the effect of centrifugal force, extraneous gas is sucked the center of centrifugal turbine, when leaving blade to surrounding, gas flow rate increases, and is blown out by the Blower Housing exhaust outlet and reaches kitchen range air blast effect thereby the gas of carrying is sent into Blower Housing.Centrifugal fan is the centrifugal turbine that relies on High Rotation Speed in casing, make the interior gas of centrifugal fan be subject to the effect of blade and produce centrifugal force, increase the kinetic energy of gas in centrifugal fan and pressure, so more existing blower, have that air quantity is moderate, blast is high, lightweight, the advantage of indices balance and stability.And the gap of centrifugal turbine periphery and Blower Housing inwall by exhaust outlet along the centrifugal turbine periphery reduce gradually to have avoided air in Blower Housing by excess compression, thereby saved the air-breathing power that consumes, make blower fan more energy-conservation.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural upright exploded view;
Fig. 2 is the utility model housing and centrifugal turbine schematic diagram.
Embodiment
As shown in Figure 1, the utility model is the special-purpose centrifugal fan of commercial kitchen tools burning machine, the namely blower of the kitchen range in special use at the restaurant.Has a motor (not shown), be connected with a centrifugal vortex wheel shaft 2 on the output shaft of motor, be provided with a centrifugal turbine 3 with axial centrifugal turbine intake grill 30 on centrifugal vortex wheel shaft 2, centrifugal turbine 3 has two annular side plate 31, between two annular side plate 31, the circle spacing is evenly equipped with blade 32, and the center hole of annular side plate 31 is axial centrifugal turbine intake grill 30; Centrifugal turbine 3 is placed in a Blower Housing 4, and Blower Housing 4 is provided with the Blower Housing intake grill 40 corresponding with axial centrifugal turbine intake grill 30 positions; Blower Housing 4 has exhaust outlet 400.Exhaust outlet 400 connects air feeding tube 5.
As shown in Figure 2, X(gap, the gap X of the periphery of centrifugal turbine 3 and Blower Housing 4 inwalls be by centrifugal vortex wheel shaft 2 axle center to the line that radially extends respectively and the distance between the intersection point of the inwall of the periphery of centrifugal turbine 3 and Blower Housing 4) reduced gradually by the periphery of exhaust outlet 400 along centrifugal turbine 3.
During use, starting electrical machinery, motor shaft drives centrifugal vortex wheel shaft 2 and then drives centrifugal turbine 3 and rotates, ambient air is sucked axial centrifugal turbine intake grill 30 from Blower Housing intake grill 40, pass again blade 32 and enter the periphery of centrifugal turbine 3 and the gap X of Blower Housing 4 inwalls, then extruded from exhaust outlet 400 and blow out and play blasting action by air feeding tube 5.
