Description
Technical field
The utility model relates to a kind of blower, and particularly a kind of is to accelerate the cooking time commercial stove is carried out the combustion-supporting blower of oxygenation.
Background technique
In order to accelerate cooking speed and accurately to grasp the duration and degree of heating, vegetable is looked good, smell good and taste good, domestic blower formula commercial stove generally adopts in the vortex type side air-out oxygenation of drum pressure blower fan combustion-supporting at present, has obtained good effect.But this blower fan is in use, has following deficiency: the one, in order to satisfy the combustion-supporting needs of cooking stove oxygenation, need to adopt 250 watts-700 watts motor, and power of motor is big, and fan efficiency is low, and power consumption is big, and energy waste is serious.The 2nd, fan noise is big, generally more than 90 decibels, brings very big noise pollution to kitchen environment, has a strong impact on cook's physical and mental health.Along with the raising of demands of social development and people's lives and working environment requirement, energy-saving and emission-reduction work is imperative, and the drum pressure blower fan has been not suitable for the social development needs in the vortex type side air-out.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have desirable product to emerge so far.
Summary of the invention
For overcoming the above-mentioned deficiency that the drum pressure blower fan exists in the existing vortex type side air-out, the purpose of the utility model provides a kind of simple and reasonable, safe and reliable to operation, power of motor is little, noise is low, fan efficiency is high balance axial flow blower.
The utility model solves the technological scheme that its technical problem adopted; It comprises motor, support, turbofan, fan casing, and described support is provided with hollow chamber, and motor is arranged on the air flow center of this hollow chamber and is fixed on the lower plate of support; The lower plate of motor periphery is provided with intake grill; The upper plate of support is provided with the central ventilation mouth less than the motor external diameter, and turbofan is fixed on the motor output shaft, and fan casing covers turbofan and is fixed on the upper plate of support; Fan casing is provided with reducing and takes over, and reducing place of fan casing is provided with the angle guide plate.
In order to prevent the output shaft infiltration, cause burn-down of electric motor to damage, described motor output shaft is provided with the tarpaulin with the electric machine casing sealing.
After adopting said structure, following advantage and effect are relatively arranged with existing technology:
The one, to blast, air mass flow requirement, the utility model is installed in the bottom of firing chamber to commercial stove, shorten air supplying distance; Fan adopts turbofan, and supporting air compartment angle wind-guiding, undergauge supercharging have effectively improved fan efficiency; Noise is low; Noise is reduced to below 65 decibels, uses 80 watts of motors just can satisfy the air feed requirement, and power savings is remarkable.
The 2nd, utilize air motor to be placed the bottom air center of flowing from going up down flow direction; Motor is carried out forced air cooling, and motor radiating is effective, converts the waste heat of motor waste heat and firing chamber to hot blast; It is combustion-supporting to bring the firing chamber heating into, has effectively improved the heat energy utilization rate.
The 3rd, the utility model power consumption is economized, and operating cost is low, and business efficiency is considerable, and effects of energy saving and emission reduction is obvious.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein 2 angle guide plates, 3 motor output shafts, 4 fan casings, 5 turbofan, 6 central ventilation mouths, 7 tarpaulins, 8 motors, 9 supports, 10 intake grills are taken in 1 reducing.
Embodiment
Shown in Figure 1, be the specific embodiments of the utility model balance axial flow blower, it comprises motor 8, support 9, turbofan 5, fan casing 4; Described support 9 is provided with hollow chamber; Motor 8 is arranged on the air flow center of this hollow chamber and is fixed on the lower plate of support 9, and the lower plate of motor 8 peripheries is provided with intake grill 10, and the upper plate of support 9 is provided with the central ventilation mouth 6 less than the motor external diameter; Turbofan 5 is fixed on the motor output shaft 3; Fan casing 4 covers turbofan 5 and is fixed on the upper plate of support 9, and fan casing 4 is provided with reducing and takes over 1, and reducing place of fan casing 4 is provided with angle guide plate 2.Described motor output shaft 3 is provided with the tarpaulin 7 with the electric machine casing sealing, can effectively solve the problem of motor infiltration causing burn-down of electric motor.
The utility model is directly installed on the bottom of cooking stove firing chamber; During work; Motor 8 drives turbofan 5 fast rotational; Air gets into from the intake grills 10 of motor 8 periphery in the hollow chamber of supports 9 and forces cooling motor 8, and turbofan 5 is through central ventilation mouth 6 extracting air in the hollow chamber of support 9, and air is seen rotation wind through turbofan 5 superchargings off from excircle; Rotation wind is taken over 1 from reducing and is discharged the straight wind that certain pressure is arranged under 2 leading roles of angle guide plate, it is combustion-supporting directly oxygenation to be carried out in the cooking stove firing chamber.
