Abstract

The utility model discloses an infrared empty-burning preventive high-efficient burner. A longitudinal run-through guide tube is disposed at the center of the burner on the basis of a service direction, a telescopic sleeve and an elastic part are successively inserted in the guide tube from top to bottom, the lower end of the elastic part is fixedly positioned on the inner side wall of the guide tube of the burner, the upper end of the elastic part is fixedly connected with the telescopic sleeve, centers of the elastic part and the telescopic sleeve are both provided with penetrating holes, the upper end of the telescopic sleeve extends out of the upper end surface of the burner, a high temperature resistant metal plate is fixedly covered at the upper end of the telescopic sleeve, and an infrared temperature measuring device is fixed at the lower end of the guide tube of the burner. The infrared empty-burning preventive high-efficient burner can effectively guarantee that the burner can fast sense dry burning of the bottom of a pan and realizes gas shut-off and fire extinguishing in time, and infrared rays emitted from the high temperature resistant metal plate can not be affected by external environment factors so that the infrared temperature measuring device is accurate in temperature sensing, thereby really guaranteeing a dry-burning function of the burner.

Description

The efficient burner of infrared ray preventing dry combustion

Technical field

The utility model relates to a kind of anti-dry burner, the efficient burner of particularly a kind of infrared ray preventing dry combustion.

Background technology

What anti-dry kitchen range in the market all adopted is to respond to cooking bottom temperature by the metal sensing probe in interior ring place, thereby reaches the purpose of anti-dry.

This structure accommodation is narrower, (its characteristics are that thermic load and efficient can not be too high to be only applicable to general kitchen range, and the form of firing is the flame envelope formula), and efficient burner is when burning, because the fire hole structure is the internal flame formula, adopts this type of form can cause its flame direct baking on sensor, makes its temperature of sensing almost all come from burner itself, and the temperature in the real the bottom of a pan is also inoperative to it, thereby makes the anti-dry function entirely ineffective.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of infrared ray preventing dry combustion efficient burner, and the efficient burner of this infrared ray preventing dry combustion is applied widely, and stable performance is not subjected to the extraneous factor shadow fully.

The utility model for the technical scheme that solves its technical problem and adopt is: the efficient burner of a kind of infrared ray preventing dry combustion, to use direction to be benchmark, the burner center is provided with a conduit that vertically connects, one telescopic and an elastic component are inserted in this conduit from top to bottom successively, the elastic component lower end is fixed positioned in burner conduit madial wall, the elastic component upper end is connected with telescopic, elastic component and telescopic center are equipped with the through hole that runs through, the burner upper surface is stretched out in the telescopic upper end, the telescopic upper end fixedly is coated with a refractory metal sheet, the positive lower end of the conduit of burner is installed with an infrared temperature measurement apparatus, when pot being placed on when hotting plate on the burner, refractory metal sheet on the telescopic presses closer the bottom of a pan under the elasticity of elastic component is ended top effect, even the outer benefit of soup juice can not flow on the refractory metal sheet yet in the pot, the temperature of refractory metal sheet and the temperature in the bottom of a pan are consistent substantially, the infrared ray of refractory metal sheet emission is received by the infrared thermometry device and changes into the corresponding signal of telecommunication, and this signal of telecommunication is transferred to the break-make gas that the burner control device is controlled burner, when the bottom of a pan because of the dry combustion method temperature when too high its infra-red intensity that sends increase, it changes into signal of telecommunication control burner and dies flame-outly, prevents that the bottom of a pan dry combustion method from causing danger.

As further improvement of the utility model, described elastic component is a spring.

As further improvement of the utility model, the structure that the elastic component lower end is fixed positioned in burner conduit madial wall is: the inboard T type through hole that is upper end diameter greater than lower end diameter of burner conduit, described elastic component lower end anchor ring presses closer the circular step face in conduit and is connected with this circular step face, this Stability Analysis of Structures, it is crooked to prevent that spring from taking place.

As further improvement of the utility model, the structure that the telescopic upper end fixedly is coated with a refractory metal sheet is: the refractory metal sheet is the cap-like structure of upper end closed lower ending opening, its lower end is sheathed on the outside, telescopic upper end and is spirally connected with it, during use, for convenience detach and the cleaning of refractory metal sheet and telescopic, easy to use.

Useful technique effect of the present utility model is: the bottom of a pan passes to the refractory metal sheet with temperature, the refractory metal sheet is basic consistent with cooking bottom temperature, its infrared ray that sends is received by infrared temperature measurement apparatus, infrared temperature measurement apparatus converts it into the signal of telecommunication and controls burner break-make gas, the quick perception of burner is also in time died flame-out when effectively guaranteeing the bottom of a pan generation dry combustion method, the infrared ray that the refractory metal sheet is launched can not be subjected to the influence of external environment factor, therefore the infrared temperature measurement apparatus temperature-sensitive is accurate, also just guarantees the function of the real anti-dry of burner.

The specific embodiment

Embodiment: the efficient burner of a kind of infrared ray preventing dry combustion, to use direction to be benchmark, the burner center is provided with a conduit 1 that vertically connects, one telescopic 2 and an elastic component 3 are inserted in this conduit 1 from top to bottom successively, elastic component 3 lower ends are fixed positioned in burner conduit 1 madial wall, elastic component 3 upper ends and telescopic 2 are connected, elastic component 3 and telescopic 2 centers are equipped with the through hole that runs through, the burner upper surface is stretched out in telescopic 2 upper ends, telescopic 2 upper ends fixedly are coated with a refractory metal sheet 4, the conduit 1 positive lower end of burner is installed with an infrared temperature measurement apparatus 5, when pot being placed on when hotting plate on the burner, refractory metal sheet 4 on the telescopic 2 presses closer the bottom of a pan under the elasticity of elastic component 3 is ended top effect, even the outer benefit of soup juice can not flow on the refractory metal sheet yet in the pot, the temperature of refractory metal sheet and the temperature in the bottom of a pan are consistent substantially, the infrared ray of refractory metal sheet emission is received by the infrared thermometry device and changes into the corresponding signal of telecommunication, and this signal of telecommunication is transferred to the break-make gas that the burner control device is controlled burner, when the bottom of a pan because of the dry combustion method temperature when too high its infra-red intensity that sends increase, it changes into signal of telecommunication control burner and dies flame-outly, prevents that the bottom of a pan dry combustion method from causing danger.

Described elastic component 3 is a spring.

The structure that described elastic component 3 lower ends are fixed positioned in burner conduit 1 madial wall is: the burner conduit 1 inboard T type through hole that is upper end diameter greater than lower end diameter, described elastic component 3 lower end anchor rings press closer the circular step face 6 in conduit 1 and are connected with this circular step face, this Stability Analysis of Structures, it is crooked to prevent that spring from taking place.
