Problems solved by technology

When this type of heater is used in heating cookers such as meat grills and chicken roasters, it is generally necessary to add a reflector on one side of the infrared heater in consideration of heating efficiency, so that the far-infrared radiation heat of the carbonaceous heating element It only radiates to one side of the object to be cooked. However, when the side of the infrared heating element with a reflective plate is placed under the object to be cooked during use, the grease or certain adherents produced when the object to be cooked is grilled It will drip on the reflector, which affects its heating effect, and it is quite troublesome to clean the stained reflector, which brings a lot of inconvenience to daily use

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0024] An infrared heater 1, comprising a glass tube and an electrified carbonaceous heating element 2, the glass tube is a double tube, which includes an inner tube 3 sealed into the carbonaceous heating element 2 and an inner tube sealed into the inner tube The outer tube 4 of the tube 3, the inner tube 3 and the outer tube 4 are all made of transparent glass, and their cross sections are all circular.

[0025] The carbonaceous heating element 2 is in the shape of an elongated thin plate. On the middle part except the two ends, there are a plurality of strips which are cut into each other alternately from the edge of one end in the length direction to the width direction and cut in at equal intervals. The slits 5 form a tortuous electrical path, and the interval between two adjacent slits 5 is determined by the specific required resistance.

Abstract

The invention relates to electric heating device, which specifically refers to an infra-red heater including the glass tube and the electrified heat body. The heat body is encased into the sealed glass tube that is a double pipe and includes the sealed inner pipe with the heat body encased and the sealed outer pipe with the inner pipe encased, and a baffle-board is set between the inside of outer pipe and the outside of inner pipe, which can make the far-infrared radiant heat generated by the heat body radiate in the regulated direction.

Description

technical field [0001] The invention relates to an electric heating device, in particular to an infrared heater which is used for heating a cooker or heating equipment, etc., and a heating element which generates radiant heat by electrification is sealed and packed into a glass tube. Background technique [0002] In the prior art, the commonly used infrared heater is to seal the slender heating element (infrared radiating element) into a slender glass tube (quartz tube), and connect the heating element to the heating element through the lead wires drawn from both ends of the glass tube. Power on. Generally, the heating element adopts a spiral filament such as tungsten, or a carbonaceous heating element that is rigid and uniform in heating. When this type of heater is used in heating cookers such as meat grills and chicken roasters, it is generally necessary to add a reflector on one side of the infrared heater in consideration of heating efficiency, so that the far-infrared...
