Spiral case blower fan include left spiral case and right spiral case, left and right spiral case, by bayonet unit by both connect be integral, it is described
Left and right spiral case, end face be provided with air inlet and base and turn on, be provided with support on the air inlet of described left spiral case, drive
Motor is arranged on the support, and motor connection wind wheel is rotated in spiral case.
Described left and right spiral case, outlet air end be provided with terminal pad, the inwall of terminal pad and ventilation shaft, which coincide, forms close
Envelope.
Described left and right spiral case, air inlet be provided with deflector, the inwall of deflector and ventilation shaft, which coincide, to be formed
Sealing.
Be provided with wind scooper above described base, the front of wind scooper is sealing structure, its surrounding offer ventilating opening with
Spiral case blower fan is turned on, and described wind scooper is connected by fixing device with base.
The beneficial effects of the utility model are:1st, simple in construction, production cost is low, improves the market competitiveness.2nd, by turbine
The ventilation shaft set of fan and axial flow fan, utilizes the advantage of turbine fan so that this show window fan has Wind Volume and low noise etc. excellent
Point.

Embodiment
Make specific further instruction to the utility model below in conjunction with the accompanying drawings.A kind of scroll casing type show window fan, is characterised by:
It includes ventilation shaft 1, and the side of ventilation shaft 1 is air outlet, and opposite side is connected with base 2, and the inside of ventilation shaft 1 sets snail
Shell blower fan 3, described spiral case blower fan 3 includes will by bayonet unit between left spiral case 31 and right spiral case 32, left and right spiral case 31,32
Both are integral in connection, and the end face of described left and right spiral case 31,32 is provided with air inlet 33 and turned on base 2, a described left side
Support 34 is provided with the air inlet 33 of spiral case 31, motor 4 is arranged on the support 34, the connection wind wheel 5 of motor 4 exists
Rotated in spiral case.
The outlet air end of described left and right spiral case 31,32 is provided with terminal pad 35, terminal pad 35 and the inwall of ventilation shaft 1
It coincide and forms sealing.
Deflector 36, deflector 36 and ventilation shaft 1 are provided with the air inlet 34 of described left and right spiral case 31,32
Inwall, which coincide, forms sealing.
Wind scooper 6 is provided with above described base, the front of wind scooper 6 is sealing structure, and its surrounding offers ventilating opening
61 are turned on spiral case blower fan 3, and described wind scooper 3 is connected by fixing device with base.
Operation principle:In this case, by the assembling ventilation shaft of turbine type, coordinate unique understructure, can make
This blower fan can be used for the places of the vertical air-out such as show window fan and use.During work, motor drives wind wheel to rotate, and wind wheel is in spiral case
Interior generation negative pressure, because spiral case assembling is in ventilation shaft, and spiral case blower fan and ventilating opening and base on ventilating opening
Conducting so that spiral case can suck air when working at the ventilating opening of base, it is achieved thereby that the purpose of air flow.
Compared with traditional axial flow blower, cleverly spiral case fan and ventilation shaft are combined in this case, with
Wind Volume, while low noise advantage, it is to avoid the drawbacks of conventional volute blower fan can only be vertical uses.In addition, the institute in this case
Wind scooper 6 is provided with above the base stated, the front of wind scooper 6 is sealing structure, and its surrounding offers ventilating opening 61 and led with blower fan 2
Logical, described wind scooper 3 is connected by fixing device with base.The structure of wind scooper side wall air intake can avoid conventional art from needing
In the front of fan, screen pack is set, therefore during the use in later stage, due to the stop without screen pack so that air stream
It is dynamic more smooth, while also avoiding dust from gathering needs often cleaning on screen pack, the ease of use of user is substantially reduced,
Therefore can be widely popularized and use.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.
