Embodiment
As shown in Figure 2, be first embodiment of the invention schematic diagram.A kind of bathroom heating and ventilating fan 100, by framework 110, the fan motor 120 be contained in framework 110, cover fan motor 120 hodmadod 140 and be arranged on Signal reception box 150 outside hodmadod 140, wind path switch boards controls motor box 160, circuit board box 170 etc. and forms, and realizes the heating of heating and ventilating fan, ventilation and functions/drying by the rotation of wind path switch boards.
Above-mentioned Signal reception box 150 and wind path switch boards are controlled motor box 160 and are connected by sealing channel 190 and form one, and this two boxes and be that sealing channel 190 is integrally formed on outside hodmadod.
Above-mentioned hodmadod outboard signal receiving box 150 is made up of lid 151 and box base 152, and wind path switch boards controls motor box 160 and is made up of lid 161 and box base 162.Lid 151,161 and the box base 152,162 of above-mentioned Signal reception box 150 and wind path switch boards control motor box 160 are integrally formed in outside hodmadod with the form of hinge structure.Hinge structure plays the effect of be tightly connected lid and box base, improves the performance of waterproof and steam-preventing, and improves the stability of product.
As shown in Figure 3, be second embodiment of the invention schematic diagram.A kind of bathroom heating and ventilating fan 100, by framework 110, the fan motor 120 be contained in framework 110, cover fan motor 120 hodmadod 140 and be arranged on Signal reception box 150 outside hodmadod 140, wind path switch boards controls motor box 160, circuit board box 170 etc. and forms, and realizes the heating of heating and ventilating fan, ventilation and functions/drying by the rotation of wind path switch boards.
Above-mentioned Signal reception box 150, wind path switch boards control motor box 160 and circuit board box 170 are all be connected by sealing channel 200 and form one, and three boxes and sealing channel 200 are all be integrally formed on outside hodmadod.
Due in air in bathroom of the outside long term exposure of hodmadod 140, and the humidity of air in bathroom is higher.By above sealing channel 190 or sealing channel 200, the above-mentioned lead-in wire 300 be integrally formed between box outside hodmadod and box is accommodated in sealing channel, can be connected between box with box.Thus, be accommodated in the signal receiving part in box, wind path switch boards controls while the electric component such as motor, circuit board can carry out electrical resistance wiring with these electric parts, air insulated that can be higher with humidity, the air preventing humidity higher invades and has received in the box of electric component.
That is, do not need resin by injection in the box of electric component is housed carries out pouring into or the ingress of lead-in wire between box and box is smeared resin and carried out cover coat or arrange seal ring each.And owing to being the structure of three box one, during assembling, disposablely outside hodmadod can fixing three boxes together, play the effect of saving cost and ease of assembly.Further, be integrally formed in the box outside hodmadod, during assembling, can save and fix the assembling procedure of box by screwing respectively outside hodmadod, play the effect of saving cost and ease of assembly.
Please refer to Fig. 3 again, above-mentioned hodmadod outboard signal receiving box 150 is made up of lid 151 and box base 152, wind path switch boards controls motor box 160 and is made up of lid 161 and box base 162, circuit board box 170 is made up of lid 171 and box base 172 (not shown), and all lids and the junction point of box base are provided with dual prominent muscle structure.Described dual prominent muscle structure refers to the dual outstanding muscle that lid and box base are respectively equipped with, and ring-type is arranged at end face.And the dual prominent muscle of lid and box base is for engaging each other connection.Because the junction of lid and box base is provided with the dual prominent muscle structure that front end band leads fillet, play during assembling while guiding location, play the effect doubling waterproof and steam-preventing.
Hereafter for Signal reception box 150, dual outstanding muscle structure is described.
The outside of Signal reception lid 151 and its inside be provided with outstanding muscle in the form of a ring, muscle 1511 protruding outside is given prominence to muscle 1512 lower than inner side and is formed, and namely to give prominence to muscle 1512 than inner side short for muscle 1511 protruding outside.Fasten for giving prominence to muscle 1522 with the inner side being arranged at Signal reception box base 152, give prominence between muscle 1512 being provided with interval at Signal reception box 151 muscle 1511 protruding outside and inner side.Like this, dual outstanding muscle structure is formed at Signal reception lid 151.
In addition, inside above-mentioned Signal reception box base 152, the outside of outstanding muscle 1522 is provided with muscle 1521 protruding outside, and the dual outstanding muscle of both image signal receiving box sides is the same to be arranged in the form of a ring.The muscle protruding outside 1521 of Signal reception box base 152 gives prominence to muscle 1522 higher than inner side, and namely the muscle protruding outside 1521 of Signal reception box base 152 gives prominence to muscle 1522 length than inner side.And, for fastening with the muscle protruding outside 1511 of above-mentioned signal receiving box lid 151, giving prominence in the inner side of Signal reception box base 152 between muscle 1522 and muscle protruding outside 1521 and being provided with interval.Like this, dual outstanding muscle structure is also formed at Signal reception box base 152.
That is, by matching of Signal reception lid 151 and signal receiving box base 152, dual outstanding muscle structure can engage mutually, and it can be made mutually to be close to.Thus can water tightness be guaranteed.And, by leading fillet to the fore-end of above-mentioned outstanding muscle, making it mutually engage and being more prone to, lid and box base positively can be made to cooperatively interact, and improve packaging efficiency.
As mentioned above, dual outstanding muscle structure is illustrated, when the situation of first embodiment of Fig. 2, the outstanding muscle 1511,1512,1521,1522 on Signal reception lid 151 and Signal reception box base 152 is arranged at other three limits except being provided with hinge structure, can improve water tightness.
Please refer to Fig. 2 again, lid and the box base junction point of above-mentioned Signal reception box 150, wind path switch boards control motor box 160 and circuit board box 170 all arrange snap-in structure.
Hereafter for Signal reception box 150, snap-in structure is described.Lid 151 arranges hook 1513, and box base 152 arranges screens 1523 accordingly, thus lid 151 and box base 152 are bonded together closely, plays the effect of water-tight and steam-preventing.
