Description

Balanced Axial Blower

technical field

The utility model relates to an air blower, in particular to an air blower for oxygenating and combustion-supporting commercial stoves in order to speed up cooking time.

Background technique

In order to speed up the cooking speed and accurately control the heat, so that the dishes are full of color, fragrance, and taste, the current domestic blower-type commercial stoves generally use vortex-type side-outlet medium-pressure blowers to oxygenate and support combustion, and good results have been achieved. However, the fan has the following disadvantages during use: first, in order to meet the needs of the stove for oxygen charging and combustion support, a motor of 250 watts to 700 watts must be used. The motor power is large, the efficiency of the fan is low, the power consumption is large, and energy is wasted serious. The second is that the fan noise is large, generally above 90 decibels, which brings a lot of noise pollution to the kitchen environment and seriously affects the physical and mental health of the chef. With the needs of social development and the improvement of people's living and working environment requirements, energy saving and emission reduction work is imperative, and the vortex type side air blower with medium pressure is no longer suitable for the needs of social development. For this reason, many manufacturers and people of insight have all carried out development and research, but do not have ideal product to come out so far.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the existing eddy current side air blower with medium pressure, the purpose of this utility model is to provide a balanced axial flow blower with simple and reasonable structure, safe and reliable operation, small motor power, low noise and high fan efficiency.

The technical solution adopted by the utility model to solve its technical problems includes a motor, a frame, a turbo fan, and a fan cover. The frame is provided with a hollow chamber, and the motor is arranged in the air flow center of the hollow chamber. And fixed on the lower plate of the machine base, the lower plate around the motor is provided with an air inlet, the upper plate of the machine base is provided with a central air vent smaller than the outer diameter of the motor, the turbo fan is fixed on the output shaft of the motor, and the fan cover The turbofan is covered and fixed on the upper plate of the machine base. The fan casing is provided with a constriction joint, and the constriction of the fan casing is provided with a slanted deflector.

In order to prevent the output shaft from seeping water and causing damage to the motor, the output shaft of the motor is provided with a waterproof cap that is sealed with the motor casing.

After adopting the above structure, it has the following advantages and effects compared with the prior art:

One is to meet the requirements of commercial stoves on wind pressure and air flow. The utility model is installed at the bottom of the combustion chamber to shorten the air supply distance. Fan efficiency, low noise, the noise is reduced to below 65 decibels, and an 80-watt motor can meet the air supply requirements, and the power saving effect is remarkable.

The second is to use the direction of air flow from bottom to top to place the motor at the center of the bottom air flow, and perform forced air cooling on the motor. The motor has a good heat dissipation effect, and the waste heat of the motor and the waste heat of the combustion chamber are converted into hot air, which is brought into the combustion chamber for heating and combustion. Effectively improve the utilization rate of heat energy. ``

Third, the utility model saves electricity consumption, low operating cost, considerable economic efficiency, and obvious effects of energy saving and emission reduction.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among them, 1 shrinking nozzle, 2 inclined deflector, 3 motor output shaft, 4 fan cover, 5 turbo fan, 6 central air vent, 7 waterproof cap, 8 motor, 9 frame, 10 air inlet.

Detailed ways

As shown in Fig. 1, it is the specific embodiment of the utility model balanced axial blower, and it comprises motor 8, support 9, turbo fan 5, fan casing 4, and described support 9 is provided with hollow chamber, and motor 8 is set at the air flow center of the hollow chamber and is fixed on the lower plate of the base 9, the lower plate around the motor 8 is provided with an air inlet 10, and the upper plate of the base 9 is provided with a center which is smaller than the outer diameter of the motor. The vent 6 and the turbofan 5 are fixed on the motor output shaft 3. The fan casing 4 covers the turbofan 5 and is fixed on the upper plate of the base 9. The necking place of 4 is provided with oblique deflector 2. The motor output shaft 3 is provided with a waterproof cap 7 that is sealed with the motor casing, which can effectively solve the problem of motor burnout caused by water seepage.

The utility model is directly installed on the bottom of the stove combustion chamber. When working, the motor 8 drives the turbofan 5 to rotate rapidly, and the air enters the hollow chamber of the frame 9 from the air inlet 10 around the motor 8 to force the motor 8 to be cooled, and the turbofan 5 passes through. The central vent 6 draws air from the hollow chamber of the machine base 9, and the air is pressurized by the turbofan 5 to send out the rotating wind from the outer circumference, and the rotating wind is guided by the inclined deflector 2 and discharged from the shrinking nozzle 1 with a certain pressure The direct wind can directly carry out oxygenation and combustion-supporting to the combustion chamber of the stove.
