Description

A kind of swingfire wind-proof energy-saving gas-cooker

One, technical field

The utility model relates to employed coal gas or natural gas cooking stove, is specifically related to a kind of swingfire wind-proof energy-saving gas-cooker.

Two, background technology

General employed gas-cooker all requires firepower powerful, and gas-cooker is equipped with air blast usually, and still, owing to be provided with air blast, when flame was smaller, wind was easy to fray-out of flame, influences cook's operation.On the other hand, the cook is when cooking operation, and is often flame-out when pot leaves cooking stove in the short time because frequent flame-out, igniting is pretty troublesome, all be unwilling to do like this.Therefore, there is the problem of combustion gas waste in present gas-cooker, moreover, untimely flame-out, also can cause the kitchen temperature to raise, worsened cook's working environment, regular meeting sees that the cook is soaked with sweat, and is very arduous.

Three, summary of the invention

The purpose of this utility model is in order to overcome the deficiency of prior art, a kind of swingfire wind-proof energy-saving gas-cooker is provided, it not only has powerful firepower, and when can prevent that flame is less, the wind-force of air blast makes it flame-out, and can light a fire automatically at any time, stop working according to cook's operation, save combustion gas.

A kind of swingfire wind-proof energy-saving of the utility model gas-cooker, comprise pot, the pot frame, the kitchen range top, air blast and kitchen range core, be characterized in: described kitchen range core is by cylindrical cyclone chamber, gas spray head, the combustion gas fire separating shield, gas spray head windproof tube and igniter are formed, described cyclone chamber is made up of inner layer wall and outer wall, between described inner layer wall and the outer wall air channel is set, described air blast is communicated with described air channel, described inner layer wall is provided with the ventilation sieve aperture, the equidirectional inclination angle that radially is provided with of described ventilation sieve aperture, middle part, described cyclone chamber below is provided with gas spray head, described gas spray head is one section floral tube with holes, described windproof tube flare, be enclosed within on the described gas spray head, the lower end of described windproof tube is connected with described cyclone chamber, the lower end of described windproof tube is provided with passage, described fire separating shield covers the upper end in described gas spray head, and be connected with the upper end of described windproof tube, described fire separating shield is a circular slab, pore is set above it, sawtooth is arranged at the edge, the inclination angle of described fire separating shield edge sawtooth and the inclination angle of described ventilation sieve aperture are equidirectional, described igniter is arranged in the described windproof tube, on the described gas supply pipe magnetic valve is set, on the described kitchen range top inductor is set, described inductor, described igniter, described air blast and described magnetic valve are connected on the automatic control circuit, described automatic control circuit is an ac power supply loop, be provided with power switch and protective tube, described automatic control circuit also is provided with the emergency power switch, contactor, described contactor has two pairs of normally closed interlocks, a pair of normally closed interlock is connected in the described igniter loop, a pair of normally closed interlock is connected in the described air blast loop, described contactor is with after described magnetic valve is in parallel, connect with described emergency power switch and described inductor again, and formation loop, when described pot is placed on the described kitchen range core, the normally closed interlock of described inductor disconnects, when described pot leaves described kitchen range core, the normally closed interlock of the described inductor closure that resets.

The utility model is because the vent screen pore area has the inclination angle, and fire separating shield edge sawtooth has the inclination angle, can form whirlwind flame, satisfies the requirement of powerful flame.Suit windproof tube on the gas spray head can be avoided the wind-force knock down the flame.

The operation principle of the automatic control circuit of the utility model setting is: during operate as normal, the emergency power switch is in closure state, the power turn-on switch, because pot is not placed on the combustion chamber, the inductor normally closed interlock is in closure state, and contactor and magnetic valve get electric, and normally open solenoid valve gets electric cutting out, two pairs of normally closed interlocks of contactor get electric back and disconnect, respectively the air blast loop of cut-out point firearm ignition circuit and air blast.When needing cooking, manually opened combustion gas main valve, as long as pot is placed on the kitchen range top combustion chamber, the normally closed interlock of inductor disconnects immediately, contactor and magnetic valve dead electricity, the normally open solenoid valve dead electricity is opened, the beginning air feed.Two pairs of normally closed interlock dead electricity of contactor, the closure that resets, the air blast loop of cut-in point firearm ignition circuit and air blast respectively.Igniter igniting 5-6 stops igniting about second, be enough to light the combustion gas in the combustion chamber during this, and air blast obtains the electric operation air blast simultaneously, sufficient combustion air is provided for the big flow combustion gas that comes from magnetic valve, obtains powerful firepower, and this moment, the cook just can carry out cooking.In the cooking process, even pot has rocking more among a small circle at combustion chamber two, inductor also is in the sense state that is subjected to always, so normally cooking.

When dish need take the dish out of the pot, as long as pot leaves combustion chamber, inductor recovers ortho states immediately, be that its normally-closed contact recovers closed by off-state immediately, then contactor and magnetic valve obtain electricity immediately, and then magnetic valve cuts out combustion gas immediately, two pairs of normally closed interlocks of contactor disconnect immediately, the ignition circuit of cut-off point firearm and the air blast loop of air blast quit work the kitchen range top respectively, are in stand-by state.If pot is placed on the combustion chamber once more, then can work again automatically in this loop, realizes lighting a fire automatically at any time, stopping working.The utility model is very energy-conservation, because the cook not only wasted combustion gas intermittently cannot not being flame-out of cooking in the past, and also can the raise temperature in kitchen of invalid burning, worsened the environment in kitchen.When using the utility model, the cook is at the intermittence of cooking, as long as pot leaves the kitchen range top, and auto extinguishing immediately, the pot one contact kitchen range top, igniting has automatically overcome invalid burning, very fuel savings immediately.

This device also has emergent manual function, and inductor is malfunctioning or when damaging, and only needs this moment emergency button disconnected get final product, manually the combustion gas main valve is opened, simultaneously power switch is closed, promptly connect ignition circuit and air blast loop, realize air feed igniting air blast, the kitchen range top still can continue to use.

The utility model has the advantages that:

1. firepower is powerful, and can prevent fray-out of flame;

2. full-automatic energy-saving control realizes that pot one is placed on combustion chamber air feed igniting air blast automatically, pot leaves combustion chamber can die automatically, turns off the blast, promptly energy-conservation labour intensity can greatly reduce cook's cooking again the time;

3. safe and reliable, have manual control;

4. control circuit power consumption, magnetic valve adopt outage to open, and air blast and ignition circuit all adopt contactor outage working method, and when making the circuit operate as normal, contactor, magnetic valve all are in off-position, thus reduction circuit power consumption.
