Description

A kind of kitchen range of automatic control large and small fire

Technical field the utility model belongs to the kitchen range of cooking, culinary art usefulness, particularly has the kitchen range that can control large and small fire automatically of energy-saving effect.

The kitchen range that background technology is used at present, several with gas-cooker, oil range and oil-gas two-way kitchen range etc. substantially.Because traditional cooking methods and the technological requirement of China needs more anxious big fire, realize frying in shallow oil frying and fry operation etc.Like this, the kitchen range on the market all add the form of air blast with the pipeline of through type, no matter whether need, all be big fire, take the dish out of the pot or unwanted big fire equal time in, just caused very big waste.This has been carried out research highly significant by many people, wherein sensor adds the state that the electronics control circuit is monitored frying pan automatically, and the action of control magnetic valve realizes size or reaches purpose of energy saving, and that the shortcoming of electronic circuit is a cost is higher, and fault rate is also than higher.An other class adopts mechanical mode exactly, directly controls pressure-reducing valve and realizes large and small fire, because the special construction of pressure-reducing valve also should not be realized, and have certain danger.Disclose a kind of gas kitchen ranges safe energy saving device among the Chinese patent ZL95243931.x, but the employing of its complicated sonde configuration and electronic amplification circuit has influenced its popularization.Chinese patent discloses a kind of coordinated type gas furnace for 892181230 kinds and has reduced flame attachment automatically, and the displacement of regulating pressure-reducing valve by a cover lever system reaches the purpose that reduces flame, and its weak point front was said.Chinese patent 892182083 discloses a kind of energy-saving gas cooker, employing is provided with the structure of a lever and controls an automatic valve in the combustion chamber, realize the purpose of large and small fire, the weak point of this structure is, lever in the combustion chamber is burnt out easily, and the valve body of automatic valve might cause gas leakage in reciprocation cycle.In order better to solve the wasting phenomenon of combustion gas (oil), designer of the present utility model has proposed goal of the invention of the present utility model after having carried out a large amount of research, and goal of the invention of the present utility model is the kitchen range of a kind of automatic control large and small fire of design.

This kind of summary of the invention be the kitchen range of control large and small fire automatically, it has stone or metal plate for standing a stove on as a precaution against fire [4], combustion chamber [10], device below stone or metal plate for standing a stove on as a precaution against fire and combustion chamber kitchen range [3] and with its steam supply valve that is communicated with by pipeline [2], magnetic valve [8] and be connected in parallel on emergency valve [9] on this pipeline, magnetic valve [8] and microswitch [7] are electrically connected with power switch [1], other with on the circumference that suitable for reading and frying pan [5] at stone or metal plate for standing a stove on as a precaution against fire [4] contacts have an expansion link [6] at least, and the lower end of this expansion link [6] is connected with the contact of microswitch [7].Isolate with refractory material between the outer tube 11 of this expansion link and the stone or metal plate for standing a stove on as a precaution against fire [4], be reduced to minimum to guarantee the thermal expansion influence that its inner expansion link [6] is subjected to.The lower end of expansion link is controlled it by a spring [13] and is resetted, and spring [13] is by gland [12] control, and when needing repairing expansion link, as long as gland is unloaded, expansion link just can be released from sleeve pipe, and is very convenient.The utility model has the advantages that conspicuously, the gravity by frying pan makes expansion link produce displacement, drives the microswitch action.Do not have other electronic component and electronic loop, simple in structure, control is reliable, has adopted emergency valve in parallel simultaneously in the loop, in order to having a power failure or during fault such as the magnetic valve that needs repairing, expansion link, still can continuing to use this kitchen range.

Appended drawings 1 is that master of the present utility model attempts, and accompanying drawing 2 is practical structure views of expansion link.The represented meaning of sequence number in the accompanying drawings is: 1, power switch, 2, steam supply valve, 3, kitchen range, 4, stone or metal plate for standing a stove on as a precaution against fire, 5, frying pan, 6, expansion link, 7, microswitch, 8, magnetic valve, 9, emergency valve, 10, the combustion chamber, 11, outer tube, 12, gland, 13, spring.

The specific embodiment is with reference to accompanying drawing, should control the kitchen range of large and small fire automatically, it has stone or metal plate for standing a stove on as a precaution against fire [4], combustion chamber [10], device below stone or metal plate for standing a stove on as a precaution against fire and combustion chamber kitchen range [3] and with its steam supply valve that is communicated with by pipeline [2], magnetic valve [8] and be connected in parallel on emergency valve [9] on this pipeline, magnetic valve [8] and microswitch [7] are electrically connected with power switch [1], other with on the circumference that suitable for reading and frying pan [5] at stone or metal plate for standing a stove on as a precaution against fire [4] contacts have an expansion link [6] at least, and the lower end of this expansion link [6] is connected with the contact of microswitch [7].The use summary is: connect power supply, when being placed on frying pan [5] on the stone or metal plate for standing a stove on as a precaution against fire [4], its weight is depressed expansion link [6], promote microswitch [7] action, connect electric loop, magnetic valve [8] electronic work is all opened pipeline, kitchen range [3] is sentenced big fire burns and is used for cooking culinary art, when frying pan [5] being held when stone or metal plate for standing a stove on as a precaution against fire [4], there has not been gravity on the expansion link, reset under the effect of the restoring force of spring [12], immediately, microswitch [7] also resets, electric loop is disconnected, magnetic valve [8] resets, and this moment, pipeline was closed by the magnetic valve major part, and kitchen range [3] is just located can only be with little fire burns.Go round and begin again like this, thereby the combination by simple control device expansion link and microswitch has realized the purpose of automatic adjusting large and small fire also just having reached energy-conservation and fuel-saving purpose.
