Abstract

The utility model relates to an electrothermal footwarmer which is characterized in that an inner and an outer heat storage insulating layers are arranged on the external side of a heating element, wherein a layer of metal protection shell is arranged on the external side of the inner heat storage insulating layer, the external side of the metal protection shell is provided with a second layer which is the outer heat storage insulating layer, and the outer shell body part is made of a metal shell of which the surface is sprayed with plastics or is made of a porcelain enamel metal shell. Besides, the utility model is provided with a temperature regulator and a double-control temperature instrument; after switched on for six to seven minutes, the utility model can be automatically switched off to use. The energy storage insulating material layers are adopted; after the utility model is switched off, heating time can be extended by a plurality of hours, the structure of the outer shell has pressurization performance and high intensity, and the utility model is convenient and practical and has no rupture; thus, when switched off to use, the utility model provides favorable safety feeling for a user.

Description

The electric heating electric foot warmer

The utility model relates to a kind of domestic heating electrical equipment, especially a kind of electric heating electric foot warmer that can be used for foot's heating in the winter time.

The warming ten minutes body health benefits of foot in winter, along with the raising of quality of the life, it is warming that people have attached great importance to foot.For this reason, existing people designed and sold electric heating electric foot warmer (electric hot plate) on the market in recent years, it is to be integral by two ceramic tile clampings up and down directly to constitute shell body, electric heating device (low-power heating wire or heat-generating disc) is housed in the middle of two blocks of ceramic tiles to be formed, during use, lead-out wire and plug insertion supply socket by the heating wire two ends get final product, in the winter time, though above-mentioned electric hot plate in occasions such as family or offices as all more convenient practicality of electric foot warmer, but also have the following defective: heat directly passes to the levels ceramic tile by heating wire, heat distributes soon, though power is little, heat utilization efficiency is low.During use, be under the situation that " live line working " promptly switches on, to warm up pin, must tractive long electric wire, use inconvenience unavoidably, add that very thin two-layer ceramic tile intensity is not good enough, usually slightly firmly just trample break, poor safety performance.

The purpose of this utility model is to overcome above-mentioned defective, thereby designs a kind of heat energy utilization rate height, and product strength is good, electric heating electric foot warmer durable in use, that power saving, especially security performance are high.

The utility model is to adopt following technical scheme to realize: it mainly is made of shell body part and electrothermal device; the outside that it is characterized in that the heater (core) as electrothermal device is provided with inside and outside two layers of heat-storage heat-preserving layer; wherein be provided with an inner layer metal containment vessel in the outside of the heat-storage heat-preserving layer of internal layer; outside at this metal coating shell is provided with the second layer again: promptly outer heat-storage heat-preserving layer, described shell body partly are to constitute (structure that can make rectangular circular or oval moulding) by surface plastic spraying or enamel metal-back.

Below in conjunction with accompanying drawing embodiment concrete structure principle of the present utility model is described in further detail.

Fig. 1 is the cross section structure schematic diagram of electric heating electric foot warmer in the utility model.

Fig. 2 is the distributed architecture sketch of each electrical component of the utility model.

Fig. 3 is an electrical schematic diagram of the present utility model.

Wherein: 1～shell body (making), 2～outer heat-storage heat-preserving layer, 3～inner layer metal containment vessel by plastic-blasting or enamel metal shell; 4～internal layer heat-storage heat-preserving layer; 5～electric heating body M, the porcelain plate socket of 6～electric heating body, 7～thermosistor D; 8～dual temperature control device T; 9～dropping resistor R, 10～LED light emitting diode lamp, 11～220VAC socket; 12～grounding reed, 13～ground wire.

With reference to accompanying drawing as can be known, when the utility model is made in specific design, also have following technical characterictic:

One, is furnished with a thermosistor D and a dual temperature control device T in the power circuit as the electric heating body 5 of electrothermal device.Wherein thermosistor D is the surface temperature that is used to proofread and correct Electric apparatus for warming feet, and dual temperature control device T is the automatic temperature controller of a kind of pre-set (temperature), can make Electric apparatus for warming feet energising outage automatically after 6～7 minutes.

Two, the medial surface as the metal-back protective layer of shell body part also can scribble one deck insulating moulding coating, and as coated one deck mercury, imitation the glass liner of a thermos flask heat preservation principle better is stored in heat in the electric foot warmer and to accomplish to control the thermal radiation curve smooth.

Three, in the power circuit of described electric heating body also and be connected to a dropping resistor R and as the LED light-emitting diode of indicator light.

Four, the described internal layer heat-storage heat-preserving layer 4 that is positioned at electric heating body 5 outsides is by silica flour (sheet), and concentration sand and asbestos material constitute, and described outer heat-storage heat-preserving layer 2 is to be made of silicate and asbestos material.

In addition: the electric heating body 5 of the utility model electric heating electric foot warmer can be made with electric hot tray, electrothermal wire heating's dish or PTC thermistor that routine is used.A cloth cover can be loaded onto in the outside in use, and mixes a pallet (figure slightly).

With reference to accompanying drawing as can be known, the circuit of this electric heating electric foot warmer adopts circuit common to constitute, wherein the energising of the dual temperature control device of used high-quality can be cut off the power supply after 6～7 minutes automatically, taking out plug just can use, owing to adopt a series of (bilayer) energy storage insulation measure and coated one deck insulating moulding coating: can be by technology coated one deck mercury film of thermos heat preservation principle with uniqueness, all heat energy effectively are stored in electric heating electric foot warmer inside, after the outage, discharge heat gradually with heating pin or heating with the temperature difference, and the time can prolong and reaches a few hours, compared with prior art, shell is solid withstand voltage, the intensity height does not break, and is not only convenient and practical, because be to use under the off-position, make user's sense of security spy good.
