Description
Technical field
The utility model relates to a kind of toilet door, particularly relates to a kind of toilet door with fan.
Background technology
Lavatory is the space of a relative closure, concerning with most people to go to toilet be a painful thing hot day, often soaked with sweat during lavatory on summer, and the foul smell in lavatory is often inconvenient to discharge (school, hospital etc. larger public lavatory situation particularly evident).Way for lavatory cooling is mainly to adopt air-conditioning or fan at present.Because the environment in lavatory is more smelly, and relative closure, few people use air-conditioning temperature-reducing: if lavatory and room share an air-conditioning, can make room peculiar smell serious, and if lavatory is installed independently air-conditioning and is wasted very much, and air-conditioning often needs cooling a period of time in advance, therefore promptness is bad.Adopt electric fan cooling often to use ceiling fan or stand fan, the former is because the small space in lavatory often can not be installed, and has electric weight wasting phenomenon, and often water is many and occupy a narrow space and lay nowhere due to lavatory for the latter, also has potential safety hazard, uses also not many.So, also there is no a kind of facilitate durable, price is relatively low lavatory cooling and the method for ventilating at present.
Summary of the invention
The problem existing for above-mentioned prior art, has designed a kind of toilet door that lavatory is carried out to automatic ventilating and extracting gases.
The utility model is achieved by the following technical solution, and a kind of toilet door with fan, comprises external door panel, internal hilar plate, fan assembly, switch and supply line.Described external door panel has the groove that numerous and door-plate are 45 degree in the horizontal direction, and making can not be inner from seeing outdoors lavatory, but can good ventilation.Described fan assembly, comprises motor, pad, fan blade, nut and case.Use screw that motor is fixed on external door panel inner surface, motor shaft has a step, and pad, fan blade are axially arranged on motor shaft successively.Utilize step outer face, use nut that pad, fan blade are axially fixed on motor shaft, utilize keyway and the cooperation of the key in fan blade endoporus on motor shaft to realize the circumferentially fixing of fan blade, use screw that case is arranged on internal hilar plate inner surface.On described internal hilar plate, having gravity vent, is square hole, and motor shaft is at the center of gravity vent, and the length of side of gravity vent is greater than the diameter of fan blade; On internal hilar plate inner surface, (lavatory is inboard) has three-position switch mounting groove, selector switch mounting groove, case installing hole, battery pack mounting groove; On internal hilar plate external surface, (outside, lavatory) has the groove that transformation and rectifier and electric wire arrangement are installed; On internal hilar plate top, have socket mounting groove; The inner surface of external door panel and the laminating of the outer surface of internal hilar plate, and two plates are fixedly connected with.Described switch and supply line, comprise a three-position switch, battery pack, selector switch, transformation and rectifier, socket and some wires.The output of three-position switch is connected with the terminals of motor, and the input of three-position switch is connected with the both positive and negative polarity of battery pack respectively, three-position switch when three different position of the switch respectively the forward of corresponding motor, stop and reversing.Battery pack is used for when not adding external power source for motor provides electric energy.Transformer is also connected with the input of three-position switch with the output of reorganizer, on the output of transformer and reorganizer and battery pack, selector switch is installed, and for selecting, adopts external power supply still to adopt powered battery.Transformation and rectifier can make the cathode voltage value of output be greater than all the time negative pole to the allowable value of motor input voltage and by rectification the voltage transformation of external AC, the input of transformation and rectifier is socket, uses indoor plug to this socket power supply.
The beneficial effect the utlity model has: 1, external door panel laterally has the some grooves (being similar to shutter) from the horizontal by 45 degree angles, both can make the people of outside, lavatory can't see the inside, lavatory (protection privacy), can also effectively ventilate.2, electric fan is arranged on toilet door, takes up room very little, and the people of being convenient to go to toilet uses at any time.When electric fan forward, can blow to lavatory, reduce the temperature in lavatory; When electric fan reverses, can extract the foul smell in lavatory, be convenient to discharge.3, every day use external power supply, adopts battery pack during power failure, even also can use when having a power failure.3, simple in structure, cost is low, and the public lavatory that is applicable to very much school, hospital, supermarket and enterprises and institutions is used.
