Description

A kind of ceiling board ventilation fan

Technical field

The utility model relates to a kind of ventilation fan, is meant a kind of ceiling board ventilation fan of built-in terminal box especially.

Background technique

Existing ceiling board ventilation fan, terminal box are set at outside the casing diapire and outside protruding from, adopt from the mode of rear portion assembling, need cover the terminal box rear seal-cover after assembling is finished and also fix, and have realized that with this external power cord is connected with the motor lighting outlet.Terminal box is positioned at the problem that box body wall has brought several aspects outward: the one, be in outside the casing owing to terminal box during assembling, this has just determined its assembly process: will be fixed on motor on the casing earlier, again casing is turned over individual, then motor down-lead, power line and capacitor are connected, and be fixed in the terminal box, this process is made troubles to assembling; The 2nd, terminal box sealed mouth and casing port are reverse, and waterproofing effect is poor, intake easily and make moist, and influence the working life of ventilation fan; The 3rd, the user is prone to error in operation in installation process; The 4th, when changing motor, disassemble casing, could change, the dismounting inconvenience is not saved customer charge.During assembling, motor is fastened on the cabinet wall by the motor frame that coincide with cabinet wall, adopts bindiny mechanism's fixed electrical machinery to bring the problem of two aspects: the one, and little, the temperature rise of the heat-dissipating space of leaving motor for, working life is short; The 2nd, the user in use, the dismounting inconvenience.The ceiling board ventilation fan that the patent No. provides a kind of easy installation and removal, has been fixed well for 99235932.5 patent, it is by the motor frame that coincide with cabinet wall and fixed by snap on cabinet wall with motor, realize purpose by changing internal structure, its structure is comparatively complicated.

The model utility content

Technical problem to be solved in the utility model provide a kind of simple in structure, assembling is efficient and convenient, be fixed well, waterproofing effect significantly, long service life, in installation process, can not produce the ceiling board ventilation fan of misoperation.

Designed a kind of ceiling board ventilation fan according to the problems referred to above, comprise casing and be assemblied in panel on the casing case mouth, cabinets cavity motor, be positioned at the terminal box on the box body wall, that its terminal box is arranged on is barrel-shaped, on the inwall of sealing under casing body, the sealed mouth of terminal box and casing port are in the same way.This terminal box and casing integrated injection molding, with the casing end face be a plane, on wall box, have wire-feeding hold, eyelet is provided with the O-ring seal that allows power line to pass.

Its assembly process is: earlier external power cord is connected with capacitor and motor down-lead, and power line and capacitor be fixed on the connector cover, O-ring seal is set on the power line, and power line is passed the wire-feeding hold of wall box, simultaneously motor and connector cover are fixed on the cabinet wall, then assemble wind wheel, wind wheel lid and panel.

Compared with prior art, ventilation fan of the present utility model has simple in structure, compact, dismounting is efficient and convenient, and good water-proof effect is easy to clean advantages such as dirt and maintaining, and noise is little, stable performance, reliable, the life-span is long, makes the terminal box volume reduce, box height descends, and has realized miniaturization.Simultaneously, can reduce electric machine temperature rise effectively, prevent that faulty operation from appearring in the user in installation process, make things convenient for the user to safeguard, change.

Description of drawings

Fig. 1 is the three-dimensional exploded perspective view after the utility model assembling.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail: as shown in the figure, ventilation fan of the present utility model comprises panel 1, wind wheel lid 2, wind wheel 3, motor 4, connector cover 5, non-return sheet 6, terminal box 7 and casing 8, described terminal box 7 is installed on the inwall of casing 8, terminal box 7 and casing 8 integrated injection moldings, with the casing end face be a plane.

During installation, on ceiling board, open earlier a sizeable mounting hole, casing 8 is installed earlier external power cord is passed mounting hole before, tighten fastening screw trip bolt simultaneously, casing 8 is fixed on the ceiling board, then external power cord is connected on the live end power line, then installation panel.During as needs cleaning or maintaining, the order of dismounting is just in time opposite with erection sequence, just no longer is repeated in this description here.When if motor breaks down, changing does not need to dismantle casing 8, directly motor 4 and connector cover 6 is disassembled, and the motor of changing 4 gets final product; Compared with prior art, dismounting is efficient and convenient, saves customer charge.

Undoubtedly; the utility model also can have multiple conversion and remodeling; be not limited in the concrete structure of above-mentioned mode of execution; for the person of ordinary skill of the art; under the prerequisite that does not break away from inventive concept of the present utility model and principle, any conspicuous distortion and improvement all are considered as belonging within the protection domain of the present utility model.

Claims (2)

1, a kind of ceiling board ventilation fan, comprise casing and be assemblied in panel on the casing case mouth, cabinets cavity motor, be positioned at the terminal box on the box body wall, it is characterized in that: described terminal box is arranged on the inwall of barrel-shaped, sealing under casing body, and terminal box sealed mouth and casing front port are in the same way.

2, ceiling board ventilation fan according to claim 1 is characterized in that: described terminal box and casing integrated injection molding, with the casing end face be a plane, on wall box, have wire-feeding hold, eyelet is provided with the O-ring seal that allows power line to pass.
