Description

Multifunctional cooker hood

The utility model relates to the ventilation unit of pump drainage oil smoke, and specifically a kind of multifunctional cooker hood is particularly suitable for being installed on pump drainage oil smoke in the family kitchen.

At present, the smoke exhaust ventilator that uses in the general family kitchen, mainly constitute by the pump drainage oil smoke fan, catchment cup, oil extraction smoke pipe and the control circuit that are installed in the casing, have basic functions such as pump drainage oil smoke, illumination and gas leakage detection alarm, when airborne pernicious gas reaches certain concentration, the control circuit that is made of gas sensor and 555 circuit starts smoke exhaust ventilator pump drainage and acoustic luminous warning automatically, can alleviate family kitchen and pollute, and is easy to use and reliable.Chinese patent: CN2085040U discloses the utility model that a kind of name is called " smoke exhaust that the cooking time prompting device is housed ", it is the timer that is connected with former smoke exhaust circuit to be housed in existing smoke exhaust cavity and the luminous and sounding type device that is connected with timer constitutes, though this smoke exhaust ventilator has the function of cooking time prompting, can not regularly close combustion gas and other burning things which may cause a fire disaster; If the generation gas leakage though can start smoke exhaust ventilator pump drainage and acoustic luminous warning automatically, does not have automatic self-closing gas, cuts off the function of burning things which may cause a fire disaster.

The purpose of this utility model is to propose high regularly the closing combustion gas, cut off the electricity supply of a kind of improved automaticity on the basis of existing smoke exhaust ventilator, if can also automatic self-closing gas when gas leakage takes place, the multifunctional cooker hood of cutting off the electricity supply.

The purpose of this utility model is achieved by the following technical solution.

A kind of multifunctional cooker hood, it mainly comprises the smoke pumping fan that is installed in the casing, the oil extraction smoke pipe, catchment cup and mainly by gas sensor Q, 555 circuit, timer, the control circuit that relay constitutes, do the cavity that to deposit one group of flavoring box at the front end of casing, in cooking process, can take easily, effectively utilized the idle space of smoke exhaust ventilator casing front end, be equipped with on the casing by timer, the out-put supply socket of relay control, can be to electric cooker, the power supply of electric cooking appliances such as electric frying pan, be equipped with in the casing and be serially connected with gas inlet pipe, combustion gas escape pipe and the electromagnetic gas valve of controlling by timer and relay, timer has four gears, when timer when " timing working gear ", can regularly power to the gas furnace air feed with to electric cooking appliance, when timer during to " zero-span ", energy automatic self-closing gas and cut-out electric cooking appliance power supply, and acoustic luminous warning, when timer when " ON gear ", general work gear for not timing, when timer when " OFF gear ", be the shutdown gear.If gas leakage is during to finite concentration, no matter timer is at arbitrary gear, detecting and change into the signal of telecommunication by the gas sensor that is installed on gas leakage detection hole amplifies through triode, import 555 circuit, trigger big electric current of output, make the relay 1J coil electricity that is installed on 555 circuit output ends, normally closed interlock disconnects, the electromagnet coil DT outage of electromagnetic gas valve, combustion gas is closed in the electromagnetic gas valve action; The power supply of out-put supply socket is cut off in relay 2J action simultaneously; The normally open contact closure of relay 1J, smoke pumping starting fan pump drainage; Buzzer FM and the acoustic luminous warning of light emitting diode simultaneously.Even under the situation that city's net has a power failure suddenly when gas leakage takes place, electromagnetism is gas-tight to be in and normally closedly promptly to close the combustion gas state, if gas leakage does not take place, when city's net has a power failure, can operate the hand push button of electromagnetic gas valve, to the gas furnace air feed.

The utility model is to do the cavity that can deposit one group of flavoring box at the casing front end of existing smoke exhaust ventilator, electromagnetic gas valve and out-put supply socket by timer, relay, gas sensor and the control of 555 circuit are housed on casing, can regularly close combustion gas and cut off the electricity supply, if but automatic self-closing gas and cutting off the electricity supply when gas leakage takes place can prevent effectively that contingency from taking place.
