Abstract

In an intelligent gas stove used for restaurants, a mini fan is mounted on the intra and external ring ventilation flue, a gas flow sensor is mounted in the intra and external ring gas supply branch channel, and a manual regulation valve and an electromagnetic valve are fixed in a total gas supply channel. An infrared object sensor is mounted on the lower part of the center of a gas header, and an electronic ignitor is fixed close to the gas header. All electronic components are connected with a control circuit and controlled by the control circuit. The utility model provides an intelligent stove used for restaurants, which can self extinguish when a cook rinses a griddle and self ignite when the griddle is putted up. The utility model has significant effect to energy saving for the restaurant, and brings about great social benefits.

Description

Restaurant's intelligent gas cooker units

Technical field the utility model belongs to gas furnace.

Background technology is present, the most restaurant of China big and medium-sized cities, hotel use the gas furnace dish-cooking, this bigger gas furnace use amount is very big, the energy that consume every day also is appreciable, but this Range structure is fairly simple, basically be exactly the single combination of a ventilating duct, air supply duct and multi-form combustion gas head, the combustion efficiency of stove and accessory is not fine; On the other hand, because the characteristics that the catering trade time for eating meals is concentrated relatively, the cook often is then dish of a dish when cooking, for reducing trouble, nearly all cook does not close burning things which may cause a fire disaster when rinsing frying pan, then fry next dish after having rinsed frying pan, and each blanking time is at least more than 10 seconds, therefore, restaurant's stove and accessory will be wasted a large amount of burnings every day.

The summary of the invention the purpose of this utility model is to provide a kind of combustion efficiency good, have pot cock off go out, pot is to restaurant's intelligent gas cooker units of fiery combustion function.The utility model comprises in one, the combustion gas head of outer burning ring structure, with internal combustion ring 3, the interior ventilating duct 5 that outer fire ring 4 joins, outer shroud ventilating duct 6, and inwardly, two the branch air supply channels in parallel that outer fire ring provides fuel gas with total air supply channel 15, interior, respectively disposed a mini fan 10 on the outer shroud ventilating duct, 11, in on each air feed branched bottom, being provided with, outer shroud

gas flow sensor

7,12, on total air supply channel, fixed a manual adjustments valve 8, fix a magnetic valve 9 at the front end of manual adjustments valve, an infrared ray object sensor 2 is arranged on the central lower of combustion gas head, fix an ignition 1 in that the combustion gas head is other, all electrical components are connected with a control circuit and by its control.

The course of work of the present utility model is as follows, after the swing arm anglec of rotation of manually-operated gate is greater than 10 °, cam 14 on the swing arm is pressed to touch switch 13, connect circuit, infrared sensor work, when combustion has frying pan in a fit of anger, infrared ray is reflected by the bottom of a pan and is received by sensor, and sensor sends the signal of telecommunication to control circuit, and control circuit is opened magnetic valve, ignition is lighted a fire simultaneously, gas flow sensor is exported the signal of telecommunication to control circuit according to the flow size of fuel gas, and the rotating speed of being controlled blower fan by control circuit is the air quantity of blower fan, to the reasonable air feed of combustion gas head, make the stove and accessory sufficient combustion, energy savings.When frying pan when the combustion gas head is removed, control circuit cuts out source of the gas automatically, blower fan also cuts off the power supply simultaneously; When putting frying pan again, stove and accessory two igniting, air feeds automatically.

The utility model provides an intelligentized restaurant stove and accessory, makes the stove and accessory sufficient combustion on the one hand, and the stove and accessory ignition temperature can be brought up to more than 1000 ℃, has satisfied the requirement of restaurant's work characteristics to the stove and accessory ignition temperature; But the utility model auto extinguishing when the cook rinses frying pan on the other hand, igniting automatically again when putting pot, the utility model is very tangible to the effect of restaurant's energy savings, can be the restaurant and directly bring economic benefit, simultaneously, China restaurant is innumerable, and its social benefit is huge.
