Patent Application
20190226701
The present invention relates generally to a technical field of ventilation device, and more particularly to a ventilation device which is mounted on a ceiling or a wall of a bathroom and capable of ventilating the bathroom.
The ventilation device has been widely used in the bathroom of the family because of its function of adjusting the air and changing the air flow. Conventional ventilation devices comprise a housing defining an internal passageway, a fan rotationally disposed within the internal passageway, and a motor disposed in the internal passageway to drive the fan to rotate. The housing has an air inlet and an air outlet communicating with the internal passageway and the outside. When air enters the internal passageway from the air inlet, the fan located in the internal passageway guides the air out of the environment from the air outlet.
However, after the conventional ventilation device is used for a period of time, the exhaust efficiency of the fan located in the housing may be reduced due to dust accumulation. This may even cause damage to the motor that drives the fan to rotate. When replacing the motor, it is necessary to hold the housing with one hand and remove the screws that lock the housing and the fan and then the motor can be taken out from the internal passageway. In this way, not only is the process of taking out the motor quite inconvenient, but also, after replacing the motor, the screws need to be aligned with the screw holes for re-locking, making the replacement process more difficult. Therefore, the structural design of the conventional ventilation device still needs to be improved.
In view of this, how to improve the above problems and develop a more simple and convenient way of disassembling and assembling the ventilation device has become the subject of the present invention.
It is an object of the present invention to provide a ventilation device that is simpler and more convenient to disassemble and assemble.
In order to solve the above problems and achieve the purpose of the present invention, the technical means of the present invention are that a ventilation device comprises a housing (1) having an receiving space (11) disposed therein, an air inlet (12) and an air outlet (13) disposed at both sides of the receiving space (11) and communicating with the receiving space (11), and a bottom cover (14) disposed at a bottom of the housing;
a plurality of positioning members (2) disposed on an inner wall of a top of the housing (1);
a fan module (3) detachably disposed in the receiving space (11) of the housing (1) and fastened to the positioning members (2); and
a power control device (4) disposed in the receiving space (11) and detachably connected to the inner wall of the housing (1); wherein the power control device (4) is electrically connected with the fan module (3) and has a wire-arranging element (41) for fixing the electric wires of the fan module (3).
More preferably, wherein the fan module (3) includes a motor (31) fastened to positioning member (2), a plurality of fixing pieces (311) disposed around an outer edge of the motor (31), a plurality of snap slots (312) disposed on one end of the filing pieces (311) and fastened to the positioning member (2).
More preferably, wherein one of the fixing pieces (311) is inwardly recessed with a receiving groove (313) for receiving an electric wire of the fan module (3).
More preferably, wherein the wire-arranging element (41) is disposed at one side edge of the power control device (4), and is a non-closed loop hook for fixing the electric wire of the fan module (3) therein.
More preferably, wherein the power control device (4) is connected to the inner wall of the housing (1) by magnetic attraction.
More preferably, wherein the power control device (4) is connected to the inner wall of the housing (1) by a hooking manner.
More preferably, wherein the power control device (4) is connected to the inner wall of the housing (1) by an adhering manner.
The present invention may achieve the following functions:
Firstly, with the design of fastening the fan module (3) to the positioning member (2) in a detachable manner, a user can push the fan module (3) to slide the fan module (3) from the side edge of the positioning member (2) and remove out of the housing (1) to allow repair and maintenance more simple and convenient.
Secondly, through the collaboration of wire-arranging element (41) and receiving groove (313), the electric wires between the fan module (3) and the power control device (4) can be fixed to achieve good wire-arranging effect and solve the problem of electric wire storage.
Thirdly, with the design of connecting the power control device (3) with the inner wall corresponding to the housing (1) in a detachable manner, the assembly and disassembly of the power control device (3) is more simple and convenient, and the installed power control device (3) is firmly fixed.
Referring to
With the design of fastening the fan module (3) to the positioning member (2) in a detachable manner, a user can push the fan module (3) to slide the fan module (3) from the side edge of the positioning member (2) and remove out of the housing (1) to allow repair and maintenance more simple and convenient.
The above two figures also show that the power control device (4) can be connected to the inner wall corresponding to the housing (1) by using magnet (5) in a magnetic attraction manner. Of course, in addition to using magnet (5) in a magnetic attraction manner, hooking (not shown in the figure) or adhering (not shown in the figure) may also be used for connecting to the inner wall corresponding to the housing (1). As a result, the installed power control device (4) can be more firmly fixed and will not be fell off in removing the bottom cover (14) of the housing (1) during maintenance. In addition, through the methods of magnetic attraction, hooking (not shown in the figure) or adhering (not shown in the figure), there is no need to use screws for connection between the power control device (4) and the housing (1), which not only simplifies the structure, but also makes the installation easier.
