Infrared dry-combustion-preventing high-efficient furnace end

Abstract

The invention discloses an infrared dry-combustion-preventing high-efficient furnace end, which is characterized in that: an application direction is adopted as benchmark, a conduit which runs through the furnace end in the longitudinal direction is arranged on the center of the furnace end, a telescopic sleeve and an elastic element are sequentially plugged inside the conduit from top to bottom, the lower end of the elastic element is fixed and positioned on the inner side wall of the furnace end conduit, the upper end of the elastic element is fixedly connected with the telescopic sleeve, centers of both the elastic element and the telescopic sleeve are provided with a through hole, the upper end of the telescopic sleeve stretches out of the upper end surface of the furnace end, the upper end of the telescopic sleeve is provided with high-temperature-resistant optical glass in an embedding way, the high-temperature-resistant optical glass just covers the through hole of the telescopic sleeve, and the positive lower end of the conduit on the center of the furnace end is provided with an infrared temperature measuring device. Due to the adoption of the infrared dry-combustion-preventing high-efficient furnace end, when the dry combustion on the bottom of a pot happens, the furnace quick can effectively sense the dry combustion and can disconnect the gas and distinguish the fire in time, infrared ray transmitted from the pot bottom is free from being influenced by the external environmental factors, so the infrared temperature measuring device is precise to measure the temperature, and the real dry-combustion preventing function of the furnace end can be guaranteed.

Description

technical field [0001] The invention relates to an anti-dry burning stove head, in particular to an infrared ray anti-dry burning high-efficiency stove head. Background technique [0002] At present, the anti-dry cooking stoves on the market all use a metal sensor probe at the inner ring to sense the temperature of the bottom of the pot, so as to achieve the purpose of preventing dry cooking. [0003] This structure has a narrow scope of application and is only suitable for general stoves (its characteristics are that the heat load and efficiency should not be too high, and the form of fire is the outer flame type), while the high-efficiency burner burns, because the fire hole structure is the inner flame type , the use of this form will cause its flame to be directly baked on the sensor, so that almost all the temperature sensed by it comes from the burner itself, and the temperature of the real bottom of the pot has no effect on it, so that the anti-dry function is complet...
