Abstract
The utility model discloses a ceiling pipe type ventilating fan with excellent air guide performance, which comprises a panel, a machine base, an air discharge pipe, a cover plate which is provided with an air inlet, a motor which is arranged in the machine base, and a wind wheel, wherein the machine base and the air discharge pipe are provided with an air channel and an air outlet which are mutually communicated; the connecting position of the top part of the machine base and the air discharge pipe is provided with a smooth transition device which is convenient for air flow; the position of the cover plate which is adjacent to the air outlet is provided with an air guide tongue. The ceiling pipe type ventilating fan with excellent air guide performance of the utility model is characterized in that because a second dead angle position is also provided with an air guide tongue which is the same with the smooth transition device which is arranged on a first dead angle position, the air resistance is reduced and the ceiling pipe type ventilating fan with excellent air guide performance is convenient for airflow to pass through. Thus, the work noise can be reduced further, the air quantity of the ceiling pipe type ventilating fan with excellent air guide performance can be enhanced and the technical performance of the ceiling pipe type ventilating fan with excellent air guide performance can be improved. The air guide tongue can realize an integral forming with the cover plate, and can also become an independent component which is connected with the cover plate by a fastener or welding or bonding or similar manners.
Description
Technical field
The utility model relates to a kind of ventilation fan, specifically a kind of ceiling pipeline type ventilation fan with good wind-guiding performance.
Background technique
Existing ceiling pipeline type ventilation fan, comprise panel, support, air outlet tube, be provided with the cover plate of intake grill and be installed on support interior motor and wind wheel, in the described support and described wind wheel corresponding part is the air channel, described air outlet tube is connected the top of a side and this side correspondence of described support, be provided with exhaust outlet in described air outlet tube, described intake grill, air channel and exhaust outlet be UNICOM successively.During work, air enters ventilation fan from the intake grill of panel, support and cover plate, converts radial air flow through wind wheel to by axial flow and goes forward side by side into the air channel, discharges from exhaust outlet then.In exhaust outlet and joint, air channel, form two air-flow dead angles, one is the joint of support top and described air outlet tube, it two is near the exhaust outlet place on the cover plate.In the prior art, be provided with the rounding off device of being convenient to air flows in position, first dead angle, the rounding off device of this air flows is the parts that the square support and the air outlet tube of circle are connected naturally in fact, its inwall is slick and sly surface, can reduce resistance of air, be convenient to the air communication mistake.
However, when air at a high speed flows into exhaust outlet in the air channel, certainly will also can form widely different stream at place, second dead angle, this will increase the operating noise of ventilation fan, has also reduced the air quantity of ventilation fan simultaneously, makes the performance of ventilation fan be subjected to bigger influence.
Summary of the invention
To be solved in the utility model is the above-mentioned problems in the prior art, aim to provide a kind of ceiling pipeline type ventilation fan with good wind-guiding performance, this ventilation fan comprises panel, support, air outlet tube, is provided with the cover plate of intake grill and is installed on support interior motor and wind wheel, be provided with the air channel and the exhaust outlet of mutual UNICOM in described support and the air outlet tube, the joint of described support top and described air outlet tube is provided with the rounding off device of being convenient to air flows, is being provided with the wind-guiding tongue near the exhaust outlet place on the described cover plate.
Ventilation fan of the present utility model, because the place also is provided with the wind-guiding tongue at second dead angle, this wind-guiding tongue is the same with the rounding off device that place, first dead angle is provided with, can reduce resistance of air, be convenient to the air communication mistake, thereby can further reduce operational noise, and the air quantity that improves ventilation fan improves the technical performance of ventilation fan.
As further improvement of the utility model, the wind-guiding tongue can be one-body molded with described cover plate, also can be individual components, is connected on the described cover plate by fastening piece, welding, bonding or similar fashion.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right sectional view of Fig. 1.
Fig. 3 is the forward view of wind-guiding tongue.
Embodiment
With reference to accompanying drawing, the utlity model has the ceiling pipeline type ventilation fan of good wind-guiding performance, comprise panel 1, support 2, air outlet tube 7, be provided with the cover plate 3 of intake grill 9 and be installed on motor (not shown) and wind wheel 10 in the support 2, be provided with air channel 6 with described wind wheel 10 corresponding parts in the described support 2, described air outlet tube 7 is connected the left side of described support 2 and the top that this side links to each other, be provided with exhaust outlet 4 in described air outlet tube 7, described intake grill 9, air channel 6 and exhaust outlet 4 be UNICOM successively.Be provided with the rounding off device 8 of being convenient to air flows in the joint of described support 2 tops and described air outlet tube 7, be provided with wind-guiding tongue 5 near exhaust outlet 4 places on the described cover plate 3, and this wind-guiding tongue 5 just in time is positioned at the joint of described air channel 6 and exhaust outlet 4.Described wind-guiding tongue 5 is an individual components, is bonded on the described cover plate 3.
What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection domain of the present utility model.
