Abstract
The utility mode discloses a speed-regulating time-delay air exchange fan. The speed-regulating time-delay air exchange fan consists of a 220 V alternating current power supply, a half-wave rectification circuit, a 18 V direct current stabilized power supply, a starting circuit, a monostable time-delay circuit and an air exchange fan motor speed-regulating circuit, and is characterized in that the model of a time-base circuit IC 1 in the starting circuit and the monostable time-delay circuit is NE555. A common characteristic of the conventional air exchange fan is that only one rotation speed is provided, the rotation speed of the air exchange fan cannot be regulated manually, and the power supply of the air exchange fan cannot be turned off automatically, so that once a user forgets turning off the power supply of the air exchange fan, electricity is wasted, a motor is burned due to overheating when the air exchange fan works for a long time, and a hidden danger of fire outbreak is left. According to the circuit of the speed-regulating time-delay air exchange fan, after a key switch (AN) is pressed once, the air exchange fan motor M works at proper speed, and after the air exchange fan motor M works for 16 to 18 minutes, the monostable time-delay circuit cuts off the power supply of the air exchange fan motor M automatically.
Description
Technical field
The utility model belongs to the air-conditioning technique field, particularly a kind of speed governing time-delay ventilation fan.
Background technique
The common feature of various model ventilation fans is on the market: ventilation fan only has a kind of rotating speed, manually can not regulate the rotating speed of ventilation fan, can not its power supply of autoshutdown.When need to take a breath in room or toilet, can only allow the ventilation fan full speed operation, after the running of ventilation fan plugged, you must constantly keep in mind and close it.In case you forget the power supply of closing ventilation fan, both caused waste electric power, also cause ventilation fan because of the overheated easy burn-out motor that works long hours, but also buried hidden danger for breaking out of fire.
The practice explanation of maintenance ventilation fan: the damage of ventilation fan causes motor load too heavy and burn out except the fan greasy dirt too much, and also having quite a few is to burn out because ventilator motor works long hours overheated.
Speed governing time-delay ventilation fan described in the utility model; after pressing one-touch switch AN; ventilator motor M is with suitable speed operation; after ventilator motor M worked approximately 16～18 minutes; the monostable time delay circuit will cut off the power supply of ventilator motor M automatically; so both effectively stop unnecessary power wastage, and also effectively protected ventilator motor can not be burned because of overheated.
Speed governing time-delay ventilation fan described in the utility model is well suited in batches exploitation, also is suitable for the air scavenger fan that factory's exploitation has the speed governing delay function.
