Abstract
The utility model discloses an infrared dry-burning preventive burner. A longitudinal run-through guide tube is disposed at the center of the burner on the basis of a service direction, high temperature resistant optical glass is fixedly covered at the upper end of the guide tube, 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 can be received via the infrared temperature measuring device through the high temperature resistant optical glass, and the infrared temperature measuring device transforms the infrared rays into electric signals to control on and off of gas of the burner. The infrared dry-burning preventive burner effectively guarantees that the burner can fast sense dry burning of the bottom of the 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 anti-dry 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 anti-dry burner, and this infrared ray anti-dry 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 anti-dry burner, to use direction to be benchmark, the burner center is provided with a conduit that vertically connects, this conduit upper end fixedly is coated with a high temperature resistant optical glass, 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 passes high temperature resistant optical glass and is changed into the corresponding signal of telecommunication by the infrared temperature measurement apparatus reception, 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 structure that the conduit upper end fixedly is coated with a high temperature resistant optical glass is: this conduit upper end is provided with the stepped hole that one section internal diameter extends out, high temperature resistant optical glass just is placed in this section stepped hole, and optical glass lower surface backstop that this is high temperature resistant is in the lower end of this stepped hole anchor ring.
Useful technique effect of the present utility model is: the infrared ray permeation high temperature resistant optical glass 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.

Fig. 2 is a perspective view of the present utility model.
The specific embodiment
Embodiment: a kind of infrared ray anti-dry burner, to use direction to be benchmark, the burner center is provided with a conduit 1 that vertically connects, this conduit 1 upper end fixedly is coated with a high temperature resistant optical glass 2, the conduit 1 positive lower end of burner is installed with an infrared temperature measurement apparatus 3, when pot being placed on when hotting plate on the burner, the infrared ray of the bottom of a pan emission passes high temperature resistant optical glass 2 and is changed into the corresponding signal of telecommunication by infrared temperature measurement apparatus 3 receptions, 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 structure that described conduit 1 upper end fixedly is coated with a high temperature resistant optical glass 2 is: this conduit 1 upper end is provided with the stepped hole 11 that one section internal diameter extends out, high temperature resistant optical glass 2 just is placed in this section stepped hole 11, and optical glass 2 lower surface backstops that this is high temperature resistant are in the lower end of this stepped hole anchor ring.
Claims (2)
1. infrared ray anti-dry burner, it is characterized in that: be benchmark to use direction, the burner center is provided with a conduit (1) that vertically connects, and this conduit (1) upper end fixedly is coated with a high temperature resistant optical glass (2), and the positive lower end of the conduit of burner (1) is installed with an infrared temperature measurement apparatus (3).
2. infrared ray anti-dry burner according to claim 1, it is characterized in that: the structure that conduit (1) upper end fixedly is coated with a high temperature resistant optical glass (2) is: this conduit (1) upper end is provided with the stepped hole (11) that one section internal diameter extends out, high temperature resistant optical glass (2) just is placed in this section stepped hole (11), and this high temperature resistant optical glass (2) lower surface backstop is in the lower end of this stepped hole anchor ring.
