Abstract
The utility model relates to an automatic exhauster. A shell body 1 is provided with a connecting opening 2 which is connected with an exhaust opening of a water heater. One longitudinal end of the shell body is provided with an exhaust fan 3, and the other end of the shell body is provided with an air outlet 4. The exhaust fan 3 is connected with a working power supply by a relay J.
Description
The utility model is relevant with soaker, and is especially relevant with the water heater soaker.
Existing water heater is by the chimney exhaust, and chimney is installed inconvenient, does not usually reach the purpose that scavenges.
The purpose of this utility model provides a kind of installation easy, is suitable for the water heater exhaust of various models, can open the automatic vent device of ventilating fan exhaust automatically with water heater working.
The utility model is achieved in that
The housing 1 of the utility model automatic vent device has the connecting port 2 that is connected with the water heater exhaust outlet, and a vertical end has exhaust fan 3, and the other end has gas outlet 4, and exhaust fan 3 is connected with working power by relay J.
Working power has transformer T, the secondary output of T is by the input of a winding relay J after the rectifier D1-D4 rectification, second group the utmost point output of T connects the water heater controller microswitch, when water is pushed microswitch connection controller open, the controller point is fought and is connected the Pneumatic valve power supply, Pneumatic valve is opened, and water heater working also touches relay J simultaneously, make its closure, connect electrical machinery of ventilator 220V power supply, ventilating fan 3 work are when cutting off the water, microswitch disconnects, simultaneously also disconnect Pneumatic valve and relay power, water heater quits work, exhaust fan stop working.
One group is output as 12V and is connected to the colelctor electrode of another termination transistor T 1 of an end J of J and the negative pole of diode D5 after the secondary output rectification of transformer T, the emitter stage of T1 meets 4 of controller LM317, the output of 5 pin and D1-D4,3 pin of LM317 connect the positive pole of diode D5 and another output of D1-D4, between two outputs of D1-D4 capacitor C is arranged, the base stage of transistor T 1 connects microswitch.
Guide plate 5 is arranged in the utility model connecting port 2.
The utility model connecting port has main support 6 supporting backstays 7, and spring 8 and Bao Ka 9 are arranged on the backstay 7.
The connecting port that the utility model adopts can adapt to the exhaust pipe mouth of commercially available various water heaters, and is flexible for installation, convenient.When people use water heater, give signal of controller with the microswitch that gas valve links, blower fan is started rapidly, air flows out to the gas outlet at a high speed by blower fan, make and form negative pressure in the housing, the waste gas that water heater is produced produces strong attraction, makes it to flow out to the gas outlet, to reach the purpose of forcing combustion gas.
Following is accompanying drawing of the present utility model:
Fig. 1 is a three-dimensional structure diagram of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is the upward view of Fig. 1.
Fig. 4 is a block diagram of the present utility model.
Fig. 5 is the utility model circuit theory diagrams.
Following is embodiment of the present utility model:
There is horizontal connecting port 2 lower end of housing 1, and both sides one end is equipped with exhaust fan 3, and the other end is gas outlet 4.Ventilating fan 3 has power line 10 and control line 11.
Connecting port 2 has garden ring main support 6, in four grooves of support 6 spring 8 is housed.Backstay 7 passes spring and is connected with arc bag card 9 with groove walls.When connecting port 2 was connected with the water heater exhaust outlet, spring force made bag card 9 compress the water heater exhaust.
The elementary 220V civil power that connects of transformer T, secondary output first group of output 12V after the rectification of D1-D4 bridge circuit succeeds the input of electrical equipment J, and output 3V connects microswitch, the igniting of cut-in point firearm behind second group of input controller LM317, while starting relay J closure, blower fan work.
