Abstract
The utility model discloses a pipeline type exhaust fan which comprises a casing, a motor and cylindrical blades, wherein the motor is fixed in the inner cavity of the casing, the cylindrical blades are fixed on an output shaft of the motor and the bottom surface of the casing is provided with an air inlet. The central shaft line of the motor is parallel to the bottom surface of the casing, the motor and the cylindrical blades are positioned at one side of the inner cavity of the casing and an air outlet at the side of the casing. The air outlet direction and the air inlet direction of the air outlet form a spatial angle of 90 DEG. The other side of the inner cavity of the casing is provided with an air inlet channel. A side surface panel of the air inlet channel of the inner cavity of the casing, which is arranged on the extension line of the central shaft line of the motor, is a mobile type panel and the panel is connected with the casing in a detachable mode. The utility model can guarantee the correct working state of a bearing and a central shaft of a motor rotor. The motor has the advantages of favorable heat radiating effect and long service life.
Description
Technical field
The utility model relates to a kind of ventilating fan, relates in particular to a kind of pipe type ventilating fan that is installed on indoor ceiling or the furred ceiling.
Background technique
It is outdoor with indoor muddy air discharge to use the pipe type ventilating fan, is commonly used.Existing pipe type ventilating fan mainly is made up of casing, motor, cylindric flabellum, its motor is fixed in the casing, and cylindric flabellum is fixed on the output shaft of motor, and the bottom surface of casing is an intake grill, on one side of casing an exhaust outlet is arranged, the central axis of motor is vertical with the bottom surface of casing.When the pipe type ventilating fan is installed on indoor ceiling or the furred ceiling, because the central axis of its motor in vertical direction, under the action of gravity of cylindric flabellum, rotor, especially under the effect of rotor gravity, the heating that can rub of the end face of rotor central shaft and the end face of bearing, so working state is contrary with the normal working of bearing, behind the motor rotation certain hour, at bearing position meeting output abnormal voice, take place with vibrations the working life of having reduced motor simultaneously.On the other hand, the radiation effect of motor of existing pipe type ventilating fan is bad, and machine operation is after a period of time, very easily heating forms high temperature, has quickened the aging of enameled cable in the motor, has reduced motor properties, thereby has further shortened the working life of motor.
The model utility content
The purpose of this utility model is at the motor bearings problem easy to wear of existing pipe type ventilating fan, and a kind of pipe type ventilating fan that makes motor bearings be in correct working state, long service life is provided.
Another purpose of the present utility model is to solve the existing bad technical problem of motor radiating effect.
The technological scheme that the utility model adopted is: the pipe type ventilating fan, comprise casing, motor, cylindric flabellum, motor is fixed in the inner chamber of casing, cylindric flabellum is fixed on the output shaft of motor, the bottom surface of casing is an intake grill, it is characterized in that: the central axis of motor is parallel with the bottom surface of casing, and motor and cylindric flabellum are positioned at a side of chassis cavity, be provided with exhaust outlet on the casing of this side, its air-out direction and air intake direction are 90 ° in space; The opposite side of chassis cavity is an air intake passage; Side panel on the elongation line of motor center axis, the chassis cavity air intake passage is movable panel, and this panel is removable the connection with casing.
Described movable panel is positioned at a side corresponding with cylindric flabellum on the casing.
Described movable panel is positioned at a side corresponding with motor on the casing, and the end away from motor on the cylindric flabellum has the baffle plate sealing, and the other end is opening-like.
Also be fixed with the little radiator shutter of a circle on the described cylindric flabellum on the end face circumference of an end of close motor, the orientation of radiator shutter is consistent with the blade of cylindric flabellum.
Described casing can be overall structure or splicing structure.
The bottom of the position of fixed electrical machinery also is provided with two oblong suction ports on the described chassis cavity, a bottom that is positioned at the motor lock chamber, and another is positioned at a side of motor lock chamber.
The beneficial effects of the utility model are: after adopting said structure, motor center axis and intake grill level, promptly when ventilating fan was installed on indoor ceiling or the furred ceiling, motor was horizontal positioned, and the central shaft of rotor and bearing all are in correct working state; On the other hand,, help the heat radiation of motor, guaranteed that motor can work at low temperatures, prolonged the working life of motor owing to increased by a circle radiator shutter at the rear portion of cylindric flabellum.
