Abstract

The utility model relates to an automatic controller for oil-fume exhauster. The upper side on the right of a controlling case is provided with an input socket, and the lower side on the right of the controlling case is provided with an input plug. The inside of the controlling case is provided with a transformer, the left side inside the controlling case is provided with a relay, a capacitor and a rectifier, and an out-leading wire on the left head face of the controlling case is provided with a temperature sensing switch which is positioned next to a liquefied gas cooker. The automatic controller automatically controls the start and stop of the lampblack presser, based on the ignition and extinguishment of the liquefied gas cooker. The utility model is simple in structure, safe and reliable in performance, low in cost, easy in production and popularization.

Description

The smoke exhaust ventilator automatic controller

The utility model relates to the automatic controller of a kind of culinary ventilation fan and smoke exhaust ventilator, the supply socket of definite say so a kind of energy automatic power and outage.

Present most of family kitchen all is equipped with ventilation fan or smoke exhaust ventilator, people often forget switch when using these electrical equipment, sometimes cause the houseful oil smoke just to find not open, sometimes ate and just found also not have powered-down after meal, so can not bring into play the effect of electrical equipment well, and produce unnecessary waste.Though have band time switch or liquefied gas to reveal other smoke pumping unit of S-class of switch on the market, price is higher, complex structure, easy break-down, practical value is obviously not high.

It is effective that the purpose of this utility model provides a kind of control, simple, cheap, safe and reliable, easy to use ventilation fan and smoke exhaust ventilator automatic controller.

Scheme of the present utility model is made up of controller housing, transformer, rectifier, relay, capacitor, power input plug, power output socket, temperature sensitive switch, its design feature is: the controller housing bottom righthand side is provided with power input plug, upper right side is provided with power output socket, the middle part is provided with transformer in the shell, left end is provided with rectifier, relay and capacitor, the three is installed on the circuit board, on the lead-out wire of shell left side temperature sensitive switch is housed.Temperature sensitive switch is that U type bimetal leaf and metal bar are fixed in the little iron pipe with heat-resistant insulation material, and the lower end is a lead, and the upper end is to seal screw.

During use input plug is inserted in the kitchen～the 220V supply socket on, ventilation fan or smoke exhaust ventilator attaching plug are inserted on the controller accessory power outlet, temperature sensitive switch is contained near the liquefied gas kitchen range.When opening the liquefied gas cooker culinary art, temperature sensitive switch is heated gradually, the switch contact closure, the transformer low voltage power supply constitutes loop energising, relay adhesive, relay contact closure through rectifier, relay coil, temperature sensitive switch,～220V power supply is communicated with power supply through input plug to accessory power outlet, this moment, oil smoke was extracted in the electrical equipment work that is opened out, otherwise, after closing liquefied gas cooker, temperature descends gradually, open circuit in the temperature sensitive switch contact, the outage of controller accessory power outlet, and smoke exhaust ventilator stops.

The utility model has the advantages that novelly, reasonable in design, simple in structure, cost is low, produces easily and promotes the use of.

Be described further below in conjunction with accompanying drawing:

Fig. 1 is the controller architecture schematic diagram;

Fig. 2 is the controller electrical schematic diagram;

Fig. 3 is the temperature sensitive switch structural representation.

Among Fig. 1, the right lower end surface of controller housing 1 is provided with input plug 4, upper right end face is provided with accessory power outlet 2, the middle part is provided with transformer 5 in the shell, left end is provided with rectifier 6 in the shell, capacitor 7, relay 10, three elements are arranged in a row and are installed on the circuit board, the shell left end is drawn lead from capacitor, the lead other end is equipped with temperature sensitive switch 3, plug 4 is inserted in the kitchen～the 220V supply socket on, ventilation fan or smoke exhaust ventilator plug are inserted on the accessory power outlet 2, temperature sensitive switch 3 is contained near the liquefied gas kitchen range, fix with screw iron sheet clip, and can adjust distance up and down with the kitchen range fire.

In Fig. 2; power input plug 4 is for having～the 220V power supply; middle inserting column is the ground protection line;～220V power supply is given the power supply of transformer 5 primary coils; and to accessory power outlet 2, the ground protection line connects the mesopore of accessory power outlet 2 by relay contact 9, and the transformer secondary output coil connects rectifier 6 inputs; rectifier output end is connected on the loop of relay 10 and capacitor 7, and the temperature sensitive switch two ends are connected in parallel on the electric capacity 7.After the liquefied gas kitchen range is lighted, the temperature sensitive switch closure that heats up gradually, the relay coil energising, contact 9 closures, smoke exhaust ventilator work, on the contrary stove extinguishes temperature sensitive switch and lowers the temperature gradually and open circuit, the relay outage, and smoke exhaust ventilator stops.

In Fig. 3, U type bimetal leaf 15 is housed in the housing 14 of temperature sensitive switch, and metal bar 16 is equipped with in the left side of bimetal leaf, and lead 17 is equipped with in the lower end of bimetal leaf and metal bar, and be fixed in the housing with heat-resistant insulation material 18, the upper end of housing is provided with seals screw 13.Temperature sensitive switch 3 usefulness screw iron sheet clips 12 are installed near the kitchen range 11 of liquefied gas 8, and when screw 13 was sealed in the stove baking, U type bimetal leaf 15 temperature distortions gradually in the little iron pipe 14 contacted energising with metal bar 16.It is upwards nearer more apart from stove that temperature sensitive switch seals screw (heat absorption iron), and it is fast more to absorb heat, and heat radiation is slow, thus adjust temperature sensitive switch about, adjust the time-delay of smoke pumping start-stop exactly.
