Abstract
The utility model discloses an infrared empty-burning preventive burner, which comprises a burner seat, a burner combination, an inner ring toothed cover and an outer ring toothed cover. The burner combination is fixed at the upper end of the burner seat on the basis of a service direction, the outer ring toothed cover is radially positioned at the outer edge of the upper end of the burner combination in a locking mode, the inner ring toothed cover is radially positioned at the center of the upper end of the burner combination in a locking mode, the center of the inner ring toothed cover is a hollow-out structure, a longitudinal run-through guide tube is disposed at the centers of the burner seat and the burner combination, located right below the hollow-out structure at the center of the inner ring toothed cover and communicated with the hollow-out structure, an infrared temperature measuring device is fixed at the lower end of the guide tube of the burner, infrared rays emitted from the bottom of a pan are received via the infrared temperature measuring device, and the infrared temperature measuring device transforms the infrared rays into electric signals so as to control on and off of gas of the burner. The infrared empty-burning preventive burner effectively guarantees 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 bottom of the pan 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
Technical field
The utility model relates to a kind of anti-dry burner, particularly a kind of infrared ray preventing dry combustion burner.
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 burner, and this infrared ray preventing dry combustion burner 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: a kind of infrared ray preventing dry combustion burner, burner comprises furnace head base, the burner combination, inner circular tooth lid and outer shroud tooth lid, to use direction to be benchmark, the burner combination is fixedly arranged on the furnace head base upper end, outer shroud tooth lid radial stop is positioned burner combination upper end outer rim, inner circular tooth lid radial stop is positioned center, burner combination upper end, inner circular tooth lid center is an engraved structure, furnace head base and burner combination center are provided with a conduit that vertically connects, this conduit is positioned under the engraved structure at inner circular tooth lid center and is communicated with it, 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, the infrared ray of the bottom of a pan emission is received by infrared temperature measurement apparatus 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, the engraved structure at inner circular tooth lid center is a through hole.
As further improvement of the utility model, this conduit is positioned at the structure that also is communicated with it under the engraved structure at inner circular tooth lid center and is: the conduit upper end is inserted in the engraved structure of inner circular tooth lid.
Useful technique effect of the present utility model is: the infrared ray that send in the bottom of a pan 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 launch in the bottom of a pan 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: a kind of infrared ray preventing dry combustion burner, burner comprises furnace head base 1, burner combination 2, inner circular tooth lid 3 and outer shroud tooth lid 4, to use direction to be benchmark, burner combination 2 is fixedly arranged on furnace head base 1 upper end, the outer shroud tooth covers 4 radial stops and is positioned burner and makes up 2 upper end outer rims, inner circular tooth covers 3 radial stops and is positioned burner and makes up center, 2 upper end, it is engraved structure that inner circular tooth covers 3 centers, furnace head base 1 and burner 2 centers of making up are provided with a conduit 11 that vertically connects, this conduit 11 is positioned under the engraved structure at inner circular tooth lid center and is communicated with it, the conduit 11 positive lower ends of burner are installed with an infrared temperature measurement apparatus 5, when pot being placed on when hotting plate on the burner, the infrared ray of the bottom of a pan emission is received by infrared temperature measurement apparatus 5 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.
The engraved structure at described inner circular tooth lid center is a through hole.
Described this conduit 11 is positioned at the structure that also is communicated with it under the engraved structure at inner circular tooth lid center: the conduit upper end is inserted in the engraved structure of inner circular tooth lid.
