Abstract

The utility model discloses an electric-heating warmer, composed of a heating plate, electric-heating elements, a cover plate, and other electrical appliance elements, wherein, the cover plate seals the electric-heating elements inside the heating plate, and the heating plate and the cover plate buckle and fix tightly with each other to form a plate structure which is 15-30CM in length and 1.5 to 5.0CM in total thickness. The heating plate is made of ceramic, the cover plate is made of plastic or metal, and a supporting rack or a supporting pin is arranged below the cover plate for making the surface of the cover plate inclined for 10 DGE to 30 DGE. The utility model consumes electricity by 20 - 200W, and the surface temperature of the heating plate slowly rises to 40-55 DGE. C. and then stays in a proper range. The utility model can be used for various office personnel, pupils and old people to warm feet when sit for a long time in winter.

Description

A kind of electric heating calefactor

The present invention relates to the small-sized electric heating appliance of foot heating usefulness.

As everyone knows, in the winter of cold, the people who bends over one's desk working in the room that does not have the heating facility is because silk ⁽⁷⁾Interfix.

5, according to the electric heating calefactor of claim 3, it is characterized in that cover plate ⁽⁴⁾Utilize the button of embracing at its edge ⁽⁸⁾Be fixed on hot plate ⁽¹⁾On.

6, according to the described electric heating calefactor of the arbitrary claim of claim 1～5, it is characterized in that heating ⁽²⁾It is resistance wire ⁽¹¹⁾, by inorganic plasticine ⁽⁹⁾Shutoff is at groove ⁽³⁾In.

7, according to the described electric heating calefactor of the arbitrary claim of claim 1～5, it is characterized in that heating ⁽²⁾It is a kind of film heating element ⁽¹⁰⁾

8, according to the electric heating calefactor of claim 6, it is characterized in that support ⁽¹⁴⁾Support hot plate ⁽¹⁾And cover plate ⁽⁴⁾, the angle α that makes heat release plane A and ground level is 10 °～30 °.

9, according to the electric heating calefactor of claim 7, it is characterized in that support ⁽¹⁴⁾Support hot plate ⁽¹⁾And cover plate ⁽⁴⁾, the angle α that makes heat release plane A and ground level is 10 °～30 °.Go out power feeder.A LED power supply indicator is arranged on the switch ⁽¹³⁾, when the switch closure rear indicator light bright.Hot plate ⁽¹⁾There is the thick punching press iron plate support of 2mm the below ⁽¹⁴⁾, the fixed screw of shared hot plate and cover plate ⁽⁷⁾Be installed in a side, make cover plate by switch ⁽⁴⁾Heat release plane A to form with ground level angle α be 23 ° the oblique state in slope.As required, but this support also the bulletin user arbitrarily unload need not.Should switch on after assembling the finishes preheating or put for a long time of this example makes in it and can dispatch from the factory after clay drying.

Embodiment two compares with enforcement one, mainly is hot plate ⁽¹⁾And cover plate ⁽⁴⁾Configuration different with material.The cover plate that this is routine ⁽⁴⁾Adopt the marble thin plate of 5mm thickness glazed colored pottery porcelain plate or glass, single-sided polishing.Hot plate ⁽¹⁾There is the high edge of 5mm that is at the edge ⁽¹⁵⁾, cover plate ⁽⁴⁾Embed on the hot plate by the edge ⁽¹⁵⁾In the plane of institute's corral.The fixed form of hot plate and cover plate can be selected fixed screw ⁽⁷⁾Binding agents such as fixing or epoxy resin, bubble flower alkali are fixed.Work as cover plate ⁽⁴⁾Be earthenware slab and when adopting screw fixedly, one deck asbestos washer is set between hot plate and the cover plate ⁽⁵⁾, to reduce the hot plate and the cover plate breakage of colliding with mutually and causing.

Embodiment three cover plates ⁽⁴⁾Identical with embodiment one, but adopt the thin-film electro backing ⁽¹⁰⁾As heating, the groove on the hot plate that adapts with it ⁽³⁾Then be fused to the dark lacuna of 4mm, electric heating piece ⁽¹⁰⁾Cover plate with metal ⁽⁴⁾Between insulating barrier is arranged ⁽⁶⁾, this insulating barrier can mica sheet or glass fabric make.This routine bulk strength is higher, sheds support ⁽¹⁴⁾After, keep flat the sentry underfooting heating that ground is suitable for standing guard especially.

Embodiment four and embodiment one relatively have than big-difference, and promptly heat release plane A is at hot plate ⁽¹⁾On.Hot plate ⁽¹⁾Be positioned at cover plate ⁽⁴⁾On, groove ⁽³⁾Open Side Down, and heat is from resistance wire ⁽¹¹⁾Pass through hot plate ⁽¹⁾Substrate is conduction upwards.Hot plate ⁽¹⁾Gross thickness be 10mm, groove ⁽³⁾Dark 5mm.Hot plate ⁽¹⁾Can select heat-resisting plastics for use, form through molding as any of the plain plastics of calcium, red soil PVC and thermosetting resin, if the technology permission also can be selected ceramic material for use.Cover plate ⁽⁴⁾Fire with potter's clay and to form thickness 24mm.Liner buffering spacer between hot plate and cover plate ⁽⁵⁾, this buffering spacer is an asbestos board, has the effect of retardance heat to the cover plate conduction concurrently.Cover plate and hot plate screw ⁽⁷⁾Fixing.

Claims (9)
