Description
Technical field
The utility model relates to a kind of ventilating fan, especially relates to a kind of assembling novel ventilating fan easily.
Background technique
Bathroom to provide people to carry out the place of having a bath or taking a shower, and when people use hot bath or shower, then have the generation of water vapour, especially in winter, the people hot water temperature used that takes a shower is higher, the temperature of hot water and the room temperature temperature difference in bathroom larger, the phenomenon that in bathroom, water smoke fills the air can be caused, easily make us feeling blurred vision, the serious even dyspneic situation of giddy that even has occurs, so people generally can at bath indoor location louver(-vre) or exhaust equipment, for strengthening the cross-ventilation in bathroom.
At present, when assembling the exhaust equipment in bathroom, extra part generally can be used for each parts of fixing exhaust equipment, as Authorization Notice No. portable warm-air drier and Authorization Notice No. warm-air drier disclosed in the patent document of CN203671930 U disclosed in the patent document of CN 203258859 U, these warm-air driers adopt screw, the latchs such as buckle fix each parts, a large amount of screws, buckle not only makes the assembling of warm-air drier loaded down with trivial details, also add the cost of production of warm-air drier, and, air bells exhauster or warm-air drier are when air draft, because the structure in air channel is reasonable not, also often make air at air channel inner impact, air is caused to flow not smooth, increase energy consumption.
For this reason, a kind of novel ventilating fan is needed.
Model utility content
The purpose of this utility model is to provide a kind of and assembles facility, novel ventilating fan that air flow resistance is little.
To achieve these goals, the utility model adopts following technological scheme:
A kind of novel ventilating fan, comprises casing and air draft assembly; Air draft assembly comprises exhaust cavity, motor and wind wheel; Wind wheel is arranged on the output shaft of motor, and motor is in exhaust cavity, and especially, exhaust cavity comprises front shroud, postnotum and guide plate; Front shroud is provided with several first fixed holes and the suction port corresponding with rotor position; Postnotum is provided with several the second fixed holes; Guide plate comprises the first arc-like sheet, the second arc-like sheet, the 3rd arc-like sheet and straight way sheet, the first arc-like sheet, the second arc-like sheet, the 3rd arc-like sheet and the tangent connection successively of straight way sheet; Position of leaving a blank is provided with between first arc-like sheet and straight way sheet; First arc-like sheet, the second arc-like sheet, the 3rd arc-like sheet and straight way sheet are provided with several first fixed plates corresponding with the first fixed hole position and several second fixed plates corresponding with the second fixed hole position.
Front shroud, postnotum and guide plate are preferably sheet metal part.
Principle of the present utility model is as follows:
The first fixed plate on first arc-like sheet, the second arc-like sheet, the 3rd arc-like sheet and straight way sheet and the second fixed plate are each passed through after in the first fixed hole and the second fixed hole, bending first fixed plate and the second fixed plate, the first fixed plate and the second fixed plate is made to be fastened on front shroud and postnotum respectively, namely complete the assembling of exhaust cavity, and form relief opening with staying empty place.
The suction port of exhaust cavity, the first arc-like sheet, the second arc-like sheet, the 3rd arc-like sheet, straight way sheet are connected successively with relief opening, form the exhaust passage of ventilating fan.Air draft assembly is arranged in casing, and air enters exhaust cavity from the suction port of front shroud, and under the drive of wind wheel, successively by the first arc-like sheet, the second arc-like sheet, the 3rd arc-like sheet and straight way sheet, discharges from relief opening.
After air enters exhaust cavity from suction port, whirlwind is formed at wind wheel place, due to the first arc-like sheet in exhaust cavity, the second arc-like sheet, the 3rd arc-like sheet and the tangent connection successively of straight way sheet, air can be very little along the resistance that the first arc-like sheet, the second arc-like sheet, the 3rd arc-like sheet and straight way sheet flow, drive the power of the motor of wind wheel without the need to the excessive degassing function that can realize large discharge, the exhaust effect of ventilating fan is good.
In order to reduce the resistance that air flows in exhaust passage further, the diameter of the first arc-like sheet is preferably 128 ~ 188mm, and the diameter of the second arc-like sheet is preferably 218 ~ 278mm, and the diameter of the 3rd arc-like sheet is preferably 140 ~ 201mm.
Can also be used for illumination by mounted LED lamp in casing, like this, ventilating fan can be directly installed on top, bathroom, and substitute the lighting burner in current bathroom, user is without the need to preparing extra installing space for ventilating fan, and as installed is more convenient.
The utility model structure is simple, and exhaust cavity adopts fixed plate to be fastened the mounting type in hole, and assembling is convenient; Guide plate in exhaust cavity adopts the tangent connection successively of polylith arc-like sheet, and air flow resistance is little, and energy consumption of electrical machinery is low.
