Embodiment
Shown in Fig. 2 A～2C, it is first embodiment's schematic representation.Shown in Fig. 2 A, a kind of bathroom heating and ventilating fan 100, comprise: ventilation fan framework 101, be provided with the ventilation fan body 110 of flabellum (not shown) and motor (not shown) etc., and be arranged at the PCB lid 121 of the covering PCB (not shown) on the framework 101 and hide the power supply lid 122 of power supply wiring section 105.Described PCB lid 121 and power supply lid 122 waterproof covers that are formed as one 120, this waterproof cover 120 are provided with and make the vertically hinge structure (not shown) of turnover of power supply lid 122.
By being set to PCB lid 121 and power supply lid 122 one-body molded, not only reduce the cost of mould, and, when installing, because PCB lid 121 and power supply lid 122 are formed as one, thus do not need to use the sealing sponge between PCB lid 121 and the power supply lid 122, certainly, also PCB need not be covered 121 and power supply 122 lid be installed in respectively on the framework 101 simplified structure.
Shown in Fig. 2 B, vertically the hinge structure 124 of turnover is independent opening power to cover 122 structure, can turn down 180 degree to Vertical direction.Cover 122 structures of independently opening by the above-mentioned power supply that makes, when the user carries out the power line connection of heating and ventilating fan, do not need whole waterproof cover 120 is removed, only need open the connection that the power supply lid 122 that hides power supply wiring section 105 just can be finished power line.And, because above-mentioned hinge structure 124 is vertically turnovers, can reduce like this to install required area.That is to say the words that the things such as crossbeam is arranged when the side of heating and ventilating fan are interfered and when causing power supply lid 122 to open, by hinge structure 124 being set to vertical turnover, connect again power line behind the body of also can slinging.Namely improved the operability of product.
In addition, also be provided with catch 1214 at the face of the PCB lid 121 that is connected with power supply lid 122.The described face that is connected the 122 PCB lids that are connected 121 with power supply refers to be respectively equipped with catch 1214 on PCB lid 121 and power supply lid above 122 crossing connections 1211, the left side 1212, by these catch 1214, PCB lid 121 and power supply lid 122 are divided into two independently spaces, even there is water to infiltrate from the gap between power supply lid 122 and the PCB lid 121, water can directly not drop on power supply wiring section 105 or the PCB yet, but flow down along above-mentioned catch 1214, flow out at last waterproof cover 120.
For another example shown in Fig. 2 A, also be provided with flange 1221 in the left and right sides of the power supplys lid 122 that joins with PCB lid 121.This flange 1221 surrounds the seam between power supply lid 122 and the PCB lid 121 from the outside, therefore, even water droplet is arranged to the gap drippage between power supply lid 122 and the PCB lid 121, by blocking of flange 1221, water droplet can directly not splash in the gap, so water droplet is difficult to enter the inside of power supply lid 122 or PCB lid 121.
Shown in Fig. 2 C, also the end face 126 with waterproof cover 120 is obliquely installed, and namely forms discharge structure in the inboard of waterproof cover 120.Therefore even having water vapor to enter waterproof cover 120 is that power supply lid 122 and PCB cover 121 when interior, setting by 126 inclinations of waterproof cover 120 end faces, when its formation dew is attached to waterproof cover 120 end face 126, can flow down along the plane of inclination of power supply lid, thereby Antidewing water directly splashes on power supply wiring section 105 and the PCB.
As shown in Figure 3, be second embodiment's schematic representation.As shown in Figure 3, be with first embodiment's difference that waterproof cover 120 is provided with and makes the laterally hinge structure 125 of turnover of power supply lid 122.Laterally the hinge structure 125 of turnover is independent opening power to cover 122 structure, can turn down 180 degree to substantially horizontal.By said structure, when the user carries out the power line connection of heating and ventilating fan, do not need whole waterproof cover 120 is removed, only need open the connection that the power supply lid 122 that hides power supply wiring section 105 just can be finished power line.And, because above-mentioned hinge structure 125 is laterally turnovers, even in the not high enough situation of the distance between ceiling board and the roof, connect again power line behind the body of also slinging.Namely improved the operability of product.
In addition, also at waterproof cover 120 perforate 130 is set.Be arranged on a side 127 of covering 122 relative waterproof covers 120 with power supply from PCB to the gas fan motor with the lead-in wire (not shown) of wind deflector motor, in body, lay from the top surface side of ventilation fan body 110 because be, so, when air during through the wind path of heating and ventilating fan, can occur to reveal and enter in the waterproof cover.
Shown in Fig. 4 A, the 4B, it is the 3rd embodiment's schematic representation.Shown in Fig. 4 A, the perforate 130 of waterproof cover 120 is arranged on the waterproof cover 120 with outlet 132 relative positions of PCB lead-in wire 150, when indoor water vapor by PCB lead-in wire 150 outlet 132 or the gap (not shown) to enter waterproof cover 120 be that power supply lid 122 and PCB cover 121 when interior, water vapor can pass through this perforate 130 from waterproof cover 120 interior evaporations, thereby prevents that it from splashing into PCB or power supply wiring section at waterproof cover 120 interior formation dews.
On above-mentioned perforate 130, be provided with strip piece 136, can prevent from like this pointing and stretch into perforate 130 and the inner parts of contact.Shown in Fig. 4 B, also below above-mentioned perforate 130, be provided with spacer 134, be provided with the waterproof sponge (not shown) that encases lead outlet 132 in PCB lead-in wire (not shown) outlet 132.When there being water droplet to drop in the perforate 130 of above-mentioned waterproof cover 120 when interior, because the spacer 134 that perforate 130 is provided with below becomes independently space with the left and right sides spatial separation of this perforate 130, and this perforate 130 is to export 132 facing to PCB lead-in wire 150, water droplet splashes into perforate 130 and can be dropped in 150 outlets 132 of PCB lead-in wire after interior, because 150 outlets 132 of PCB lead-in wire are provided with the waterproof sponge that encases lead outlet, like this, water droplet is dropped on the waterproof sponge, blocked by waterproof sponge and to flow away around it, can not flow on power supply wiring section and the pcb board.
As shown in Figure 5, be the 4th embodiment's schematic representation.Be that with the 3rd embodiment's difference the position of the perforate of offering on the waterproof cover 120 is different.Perforate 140 is arranged on the waterproof cover 120 that the outlet 132 with PCB lead-in wire 150 is staggeredly located, the perforate 140 that is provided with by waterproof cover 120, when indoor water vapor by PCB lead-in wire 150 outlet 132 or to enter waterproof cover 120 be that power supply lid 122 and PCB cover 121 when interior in the gap, water vapor can pass through this perforate 140 from waterproof cover 120 interior evaporations, thereby prevents that it from splashing into PCB or power supply wiring section at waterproof cover 120 interior formation dews.
In addition, also be provided with location piece 141 below above-mentioned perforate 140, this location piece 141 is fixed on extreme lower position with PCB lead-in wire 150, like this, on lead-in wire 150, dew is arranged, also can not flow back in the PCB, but flow to the extreme lower position that goes between along PCB lead-in wire 150.
And, the plate face 128 of the waterproof cover 120 of the both sides of perforate 140 is set to the structure of perforate 140 inclinations, like this, when the water recovery that enters from 150 outlets 132 of PCB lead-in wire or gap becomes water droplet to be attached on the plate face 128 of waterproof cover 120, plate face 128 along the waterproof cover 120 of leaning structure, water can flow to perforate 140 positions, flows out at last, and can not flow in the PCB lid 121 along waterproof cover.Product performance and Security have been improved.
