Abstract
The utility model provides a ventilation fan, comprising a snail shell, a motor, an air intake face mask and a frame. The utility model is characterized in that an electric parts box and a connection box are arranged outside the snail shell, the electric parts box contains an electric part which is connected with the lead wire of the motor, and the connection box contains a power wire connecting terminal which is connected with the lead wire of the motor. As the wire connecting terminal of an internal electrical power lead wire, a power supply wire and a capacitor are placed separately, the utility model has better safety.
Description
Technical field
The utility model relates to a kind of electric product, refers in particular to a kind of ventilation fan.
Background technique
In the modern life, the use of ventilation fan is very widely.Shown in Figure 1A, Figure 1B, ventilation fan 1 is formed main body by hodmadod 2 and motor 3 and air intake face shield 4 usually, is placed among the framework 5.Be integrally formed with an electrical part product box 10 in hodmadod 2 outsides.Tenminal block 22 between tenminal block 21 between motor leads 11 and the internal electric source lead-in wire 12, motor leads 11 and the electric capacity lead-in wire 13, and in all ccontaining this electrical part product box 10 of electric capacity 6.On framework 5 walls, be provided with power box 30, be connected to power box 30, when this ventilation fan is installed, as long as external power supply is received the internal electric source lead-in wire 12 of power box 30 by internal electric source lead-in wire 12.
But said structure is being guaranteed its safe handling and is being made things convenient for the client to use design aspect to be short of to some extent.
1, because ventilation fan is a capacitor operating motor type product, electric capacity is important safety portion product, so should protect electric capacity to greatest extent.But in existing product, the tenminal block 21 of the tenminal block 22 of electric capacity lead-in wire 13, internal electric source lead-in wire 12 all places same electrical part product box 10 with electric capacity 6, the client went between 12 o'clock at the installation internal electric source, might accidental damage electric capacity 6 or electric capacity lead-in wire 13 and motor leads 11 thrown off, cause product not run well.
2, electric capacity 6 is placed in the electrical part product box 10 with tenminal block 21,22, and electric wire is messy a bit, and the space is little, and the client is difficult for installing internal electric source lead-in wire 12.
Client's installation or replacing internal electric source went between 12 o'clock like this, when opening the lid of electrical part product box 10, will feel dazzled, did not know that where to start, or the mistake of taking out stitches.
The model utility content
The purpose of this utility model is, a kind of ventilation fan is provided, and tenminal block, power line that internal electric source is gone between separate placement with electric capacity, have better Security.
For achieving the above object, a kind of ventilation fan that the utility model provides comprises hodmadod, motor, air intake face shield and framework, establishes an electrical part product box and a terminal box in the hodmadod outside; Ccontaining electrical part product in the described electrical part product box, these electrical part product are connected with motor leads; A ccontaining power supply terminal in the described terminal box, this power supply terminal is connected with motor leads.Described electrical part product comprise electric capacity.
Described ventilation fan, wherein electrical part product box and hodmadod are one.
Described ventilation fan, wherein terminal box and hodmadod are splits.
Described ventilation fan, wherein the power interface position of power supply terminal reservation is provided with power supply and inserts sign.
Described ventilation fan, wherein the space is left in the power interface position of power supply terminal reservation, is positioned at the front of opening side.
As from the foregoing, by in framework, be provided with hodmadod be the power box that the terminal box of split replaces the framework peripheral hardware of known technology, the utlity model has following advantage:
1. because electric capacity is placed in the electrical part product box in addition, and the client only operates terminal box when connecting power line, therefore can not touch electric capacity and accidental damage electric capacity or electric capacity lead-in wire and motor leads thrown off, electric capacity just manys one deck protection than common product like this.
2. when connecting power line, because of having only a power supply terminal in the terminal box, and there is wiring to indicate, therefore will feels that terminal box is clean and tidy, orderly;
3. in the limited space of terminal box, reserve maximum space before the power supply terminal, make things convenient for the client to connect power line.
4. because not at framework peripheral hardware power box, so the ventilation fan compact overall structure, be convenient to install.
Therefore 5. because terminal box design for split, can disassemble flexible installation power line when installing and keeping in repair, also can change the importing direction of power line, also can carry out the shared of this terminal box with ventilation fan not in other models of back panel wiring.

Figure 1B is the local enlarged diagram of known ventilation fan;
Fig. 2 A is the schematic perspective view of the utility model ventilation fan;
Fig. 2 B is the local enlarged diagram of the utility model ventilation fan.
Embodiment
Shown in Fig. 2 A, the utility model ventilation fan 1 is integrally formed with terminal box 200 of an electrical part product box 100 and split design in hodmadod 2 outsides.
As Fig. 2 B as seen, draw five lead-in wires from motor 3, promptly first the lead-in wire a, second the lead-in wire b, the 3rd the lead-in wire c, the 4th the lead-in wire d and the 5th the lead-in wire e, wherein first the lead-in wire a and the 3rd the lead-in wire c be same terminal.
See also Fig. 2 A and Fig. 2 B again.The first lead-in wire a is connected with electric capacity 6 with 111 by electric capacity tenminal block 110 respectively with the second lead-in wire b.Other the 3rd lead-in wire c, the 4th lead-in wire d and the 5th lead-in wire e are live wire, ground wire and zero line in regular turn, receive respectively on the power supply terminal 120, and this power supply terminal 120 is reserved power interface 140.
During installation, at first the first lead-in wire a is connected with electric capacity 6 with 111 by electric capacity tenminal block 110 respectively with the second lead-in wire b, is housed in the electrical part product box 100; Then the 3rd lead-in wire c, the 4th lead-in wire d and the 5th lead-in wire e are received respectively on the power supply terminal 120; After terminal box 200 is positioned at hodmadod 2 one sides and is provided with an opening side 210, the three lead-in wire c, the 4th lead-in wire d and the 5th lead-in wire e and passes opening side 210, power supply terminal 120 fixedly is housed in the terminal box 200; At last terminal box 200 is fixed on the electrical part product box 100.
In the position of framework 5 corresponding terminal boxes 200, be provided with a power line and introduce hole 51.
During user installation circumscripted power line 52, only power line 52 need be introduced on 51 access power supply terminals, the 120 reservation power interfaces 140 of hole getting final product by power line.At terminal box 200 internal wirings, the utility model is provided with power supply in the power interface position that power supply terminal 120 is reserved in advance and inserts sign, indicates live wire, ground wire and zero line interface respectively for the convenience of the user.And reserve enough installing spaces in the place ahead of power supply terminal 120.
Because terminal box 200 is split designs, if the user according to aforementioned manner still inconvenience install, can be about to terminal box 200 and electrical part product box 100 earlier break away from, again with power supply terminal 120 taking-ups, after connecting power line 52, again that power supply terminal 120 and terminal box 200 is fixing.During maintenance, also be can be like this.
