Abstract
The utility model relates to a ventilating fan comprising a wind wheel, an electric motor, a volute, a supporting plate, a box body, an air outlet, a face plate, etc. The blades of the wind wheel are centrifugal type blades, the volute and the supporting plate cover the wind wheel, the volute is provided with round openings around the blades, and an opening is in alignment with the air outlet of the box body. The utility model is installed below a ceiling, and the air can be exhausted outdoors through a pipeline. The ventilating fan can be used for a room, the four walls of which are adjacent to other rooms, and the effect of ventilation of the middle of a large room can be improved. Meanwhile, the labor strength of the installation is reduced.
Description
The utility model relates to a kind of ventilation fan.
Traditional ventilation fan is generally axial flow, does not change direction during air-flow turnover fan, and this ventilation fan generally can only use on divider wall, can not be used in the wall room adjacent with other rooms, and to the intermediate portion than big room, ventilation effect is also relatively poor.Simultaneously, on divider wall, install, also increased labor intensity.
The purpose of this utility model just be to overcome the ventilation effect of traditional ventilation fan poor, the big shortcoming of labor intensity is installed, provide a kind of air intake to air-out in vertical direction ventilation fan.
The utility model is achieved in that its main structure comprises parts such as wind wheel, motor, spiral case, support plate, casing, exhaust outlet, panel.Centrifugal type wind wheel and motor are fastening by spiral shell, and motor is fixed on the support plate; Spiral case covers on the wind wheel periphery and links to each other with support plate, and spiral case has circular open around fan blade, and other has an opening to be parallel to motor shaft, and aims at the exhaust outlet of casing; Support plate links to each other with casing with screw with spiral case, and is contained in the casing, casing be parallel to motor shaft, be panel perpendicular to the one side of exhaust outlet, in order to air inlet.
Like this, the utility model becomes the airintake direction ventilation fan vertical with outgassing direction with regard to the linarity air-flow (axial flow) of a confrontational ventilation fan.By pipeline, gas is drained into outdoor.It is installed in is used in wall on the ceiling board and other room is adjacent room, also can improve the ventilation effect of the intermediate portion of big room.On ceiling board, reserve simultaneously station is installed, can reduce installation labor intensity, convenient construction.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the schematic representation of spiral case one side of the present utility model.
Fig. 2 is the schematic representation of support plate one side of the present utility model.
Among the figure, wind wheel (6) blade profile is centrifugal arc, and blade is parallel to the axis of motor, fixes along the peripheral equidistant arrangement of wind wheel, and wind wheel (6) is fastening by the spiral shell width of cloth and motor (2), and motor (2) is fixed on the support plate (13); Spiral case (4) covers on the wind wheel periphery and links to each other with support plate (3), and spiral case has circular open around wind wheel blade, and other has an opening (8) to be parallel to motor shaft, and aims at the exhaust outlet (7) of casing; Support plate (3) links to each other with casing (1) with screw with spiral case (4), and is contained in the casing, at the motor shaft that is parallel to of casing, one panel (5) is arranged in order to air inlet perpendicular to the one side of exhaust outlet.By pipeline (9), can be expelled to gas outdoor from panel (5) suction.
Claims (2)
1. a ventilation fan comprises wind wheel, motor, spiral case, support plate, casing, exhaust outlet, panel, it is characterized in that wind wheel and motor are fastening by spiral shell, and motor is fixed on the support plate; Spiral case covers on the wind wheel periphery and links to each other with support plate, and spiral case has circular open around fan blade, and other has an opening to be parallel to motor shaft and aims at the exhaust outlet of casing; Support plate links to each other with casing with screw with spiral case, and is contained in the casing, casing be parallel to motor shaft, be panel perpendicular to the one side of exhaust outlet.
2. ventilation fan according to claim 1 is characterized in that the cross section of wind wheel blade is centrifugal arc, and blade is parallel to the axis of motor, fixes along the peripheral equidistant arrangement of wind wheel.
