Abstract

The utility model discloses an electric heating infrared radiator. The utility model is characterized in that the core of a heating element is a mushroom head with a long manubrium, the facade of the mushroom head is of dished conical surface, the reverse of the mushroom head is of male cone, a large parabolic reflector is corresponding to the male cone; the heated resistance wire is arranged in a plurality of circular grooves in the male cone, the radial grid bars on the groove position the resistance wire by blocking the resistance wire in the groove, the heat energy first irradiates on the parabolic reflector, then the parabolic reflector reflects the heat energy to the right front; the inner conical surface of the mushroom head headed by the resistance wire and radiates infrared heat energy to right front for composing the double radiation surfaces infrared electric heater.

Description

Mushroom shape double radiation surface infra red eletric heating device

The flushing outer electric heater of a kind of mushroom biradial of the usefulness of warming oneself belongs to the electric-heating technology field.

The electric heating device of Shi Yonging normally has only the one side radiant heat energy in the market, for example is a parabola, semicolumn allusion quotation face, plane etc., and radiation efficiency is low.

The purpose of this utility model provides a kind of flushing outer electric heater of biradial with a parabola and taper a face.

Be described in detail content of the present utility model below in conjunction with accompanying drawing.

The utility model is by heater core 5, radiation shield 2, back cover 1, the base for supporting 9 of safety cage 6 and animal heading shape constitutes, the structure of shaking the head neck and facing upward head mechanism 7 on the base for supporting 9, identical with utility model patent 91231048, critical component of the present utility model is a kind of mushroom biradial face heater core 5, it is as the mushroom with long handle, the head of mushroom is the taper seat 15 of indent, it is shape positive radiation face, its reverse side is a male cone (strobilus masculinus) 16, be the collateral radiation face, pair is penetrated a few circle shape grooves 14 on the face, vertical with groove 14 have several radially grid rods 13, the edge of it and groove 14 is sintered to fix, groove 14 inner discs are placed with resistance wire 3, it is stopped the location by grid rod 13, corresponding with the male cone (strobilus masculinus) 16 of heater core 5 is a radiation shield 2, it is a smooth parabola, its reflecting surface area is bigger approximately 7～8 times than the area of inner conical surface 15, constitute dual heat energy radiating surface with the inner conical surface 15 of heater core 5, the mushroom neck 12 of heater core 5 is longer, its afterbody has two inclined holes 10, electric wire fairlead as resistance wire, hole 11 is installing holes, with long spiro nail heater core 5 is fixed on the radiation shield 2, shock-proof spring 4 is arranged between screw and the nut, radiation shield 2 and back cover 1, safety cage 6 usefulness screws 18 are fixed together, its fixed form is the centre that radiation shield 2 is clipped in back cover 1 and safety cage 6, the upwards curved allusion quotation of one end becomes circle shape upholstery border 19, one end of guard 6 curves spherical flange 17, and whole radiation appliance is connected with the neck 8 of shaking the head on the base 9 by the head mechanism 7 of facing upward on the back cover 1.

The utility model has the advantages that owing to adopt the biradial of little inner conical surface 15 and big radiation shield 2 to face a direction infrared radiation heat energy, so radiation efficiency height, compare with the infrared ray electric heater of equal-wattage, can save 20% electric power, simultaneously because the mushroom neck 12 on the heater core 5 is long, heat seldom is transmitted to its afterbody, so heat energy to each divergence loss of negative side seldom.

Be accompanying drawing of the present utility model below:

Accompanying drawing 1 is a side sectional view of the present utility model;

Accompanying drawing 2 is cutaway views of heater core 5;

Accompanying drawing 3 is top views of the male cone (strobilus masculinus) 16 of heater core 5;

Accompanying drawing 4 is connection layouts of radiation shield 2 and back cover 1, safety cage 6 usefulness screws 18.

Luffing mechanism and oscillating mechanism with reference to accompanying drawing 1-4 and utility model 91231048 are easy to implement the utility model.

Claims

1, a kind of infrared ray electric heater, by heater core 5, back cover 1, radiation shield 2, safety cage 6 and the animal shape heading pedestal 9 that supports it constitute, it is characterized in that heater core 5 is a kind of mushroom taper seat 15 and male cone (strobilus masculinus)s 16 with indent, the former is a positive radiation face, the latter is the collateral radiation face, collateral radiation face 16 has been done a few circle shape grooves 14, vertical with groove 14 have several radially grid rods 13, the edge of it and groove 14 is fixing around knot, groove 14 inner discs are placed with resistance wire 3, it by grid rod 13 stop the location corresponding with the male cone (strobilus masculinus) 16 of heater core 5 be a radiation shield 2, it is a smooth parabola, its reflective surface area than inner conical surface 15 big 7-8 doubly, it and the dual heat energy radiating surface of shape inner conical surface 15 formations of heater core 5, heater core 5 is fixed on the radiation shield 2, radiation shield 2 and back cover 1, safety cage 6 is fixed together, and is fixed on the animal heading shape pedestal 9 by the head mechanism 7 of facing upward on the back cover 1.

2, by the described electric heater of claim 1, it is characterized in that the afterbody of the mushroom neck 12 on the heater core 5 has screw 11, electric wire fairlead 10 is used screw by hole 11, and nut fixedly heater 5 has shock-proof spring 4 at the center of radiation shield 2 between screw, the nut.

3, by the described electric heater of claim 1, it is characterized in that the fixed form between back cover 1, radiation shield 2, the safety cage 6 is fixing with a screw 18, radiation shield 2 one ends that are clipped in the middle are made upwards curved allusion quotation and are become circle shape upholstery border 19, and an end of guard 6 curves spherical flange 17.
