Abstract

The double-function electric foot warmer mainly comprises a heat-collecting warm-keeping cover, a base, an electric heating element and the like. The heat generated by the electric heating element is released into the warm-keeping cover through the radiator, and the feet (without taking off shoes) extend into the cover and step on the radiator, thus achieving the purpose of warming feet. In addition, the wet shoes, socks and other articles can be dried. Unique structure, convenient use, safety, sanitation, energy conservation and dual purposes. The multifunctional electric foot warmer is widely suitable for foot freezing prevention and warming of people who frequently sit, and for household shoes and socks drying, and is a practical novel double-function electric foot warmer.

Description

Double-function heating foot warm apparatus

This utility model relates to a kind of difunctional electric heating foot warmer, and particularly a kind of antifreeze heating of foot that promptly can be used for people can be used for drying by the fire the electric heating foot warmer of footwear, socks again.

Existing electrically warmed shoe, electric heater and this utility model relatively, the former two's structure is complicated, the manufacture difficulty of drawing materials is big, cost is higher, inconvenient maintenance, service life is short, power consumption is big, function singleness, use inconvenience, not too is fit to people's requirement.

People are when be seated work, study winter at present, often endure cold and cause work, study inconvenience because of foot cold, unless soft coal fire or charcoal fire heating underfoot, adopt these traditional method heatings, one does not save coal, the charcoal energy, two is unhygienic, dangerous, the personnel (as warehouse, sales counter personnel etc.) of the incompatible especially general unit that prevents fires, foot heating.Still lack this series products of electric heating shoe baking device in addition in the market, people will wash wet footwear article in the winter, be difficult to airing for the moment as day rain, bring many troubles to people, this utility model has solved this problem, general using will be washed wet footwear article and put into above the radiator of foot warmer night, can dry in several hours, realize that a device is dual-purpose.

The purpose of this utility model provides a kind of easy to use, safe, health, economical and practical in the winter of cold for people exactly, can warm oneself, and can dry the difunctional electric heating foot warmer of footwear, hosiery article again.

Structure of the present utility model and operation principle are as follows:

With reference to Fig. 1,2,3,4,5.

Fig. 1 is the structure chart of axonometric chart of the present utility model and thermal-arrest thermal cover (4);

Fig. 2 is the structure chart of base among Fig. 1 (11);

Fig. 3 is first kind of structure chart of radiator among Fig. 2 (19);

Fig. 4 is second kind of structure chart of radiator among Fig. 2 (19);

Fig. 5 is a circuit diagram of the present utility model.

The utility model is by formations such as thermal-arrest thermal cover (4), yoke (22), heating (33) and radiators (19). See Fig. 1: thermal-arrest thermal cover (4) exceptionally (7) in (6), inner (10) 3 layers, outer (6) is turf or artificial fur, chemical fibre flannelette etc.; Middle level (7) is the thick sponge of 1cm, and nexine (10) is general flannelette. Thermal-arrest thermal cover (4) is made and is formed by (5), (14), (15) 3 blocks of raw materials that cut, and (13) are sewing line. The rear portion of thermal-arrest thermal cover (4) is provided with the dodge gate of band nylon tower button (8), is convenient to both feet and comes in and goes out. The thermal-arrest thermal cover (4) of making is fixed on the base (11) with nail and press strip (17), is stained with decorative plastic band (16) at press strip (17) then. See accompanying drawing 2: base (11) is by yoke (22), and 4 are supported iron rod (20), radiator (19), base plate (24), the compositions such as supply socket (21). Radiator (19) is made of the thick galvanized iron sheet of 0.5mm. In the radiator (19) fixedly heating (33) two kinds of methods are arranged; (seeing accompanying drawing 3); First kind is to make the synthetic tubulose of the two and half garden shape pipe boxes (34) identical with heating (33) radius, the heating of wherein packing into (33), usefulness wire clip (35) clamping; (seeing accompanying drawing 4). Second is that fixedly heating (33) radiator (19) is by Homogeneouslly-radiating face (30) by barb-type parents-in-law tenon (36), and lower heat transfer plate (31) two and half garden shape pipe boxes (34) or barb-type parents-in-law tenon (36) form. Radiator (19) iron rod (20) that is 5mm with 4 diameters is fixed in the go forward appropriate location of after-frame of yoke (22), and 4 iron rods (20) namely play the effect of fixed heat sink (19), have played again the effect of supporting both feet heatings. At the front middle part of radiator (19), with screw (28) insulating paper (26) and porcelain binding post (27) are fixed thereon, be convenient to power line (29) and heating (33) wiring. Electric heating unit Hot line Electric soldering iron core (35W) in part (33) adopts. Settled a supply socket (21) in the front portion of base (11), be communicated with two short leads (29) between its socket (21) and the heating (33), and lead is fixed on yoke (22) lower front. Power supply indicator (18) is fixed on unprecedented section place in the base (11), and whether be convenient to viewing lamp (18) has electric current to exist. At the below of base (11) sheet metal bottom board (24) back cover of 0.35mm, and be provided with 4 landing legs (25).

Accompanying drawing 5 is circuit diagrams of the present utility model, and when plug (1) was connected the 220V AC power, indicator lamp (18) sent ruddiness, being shown with electric current exists, heating (33) produces heat simultaneously, discharges heat energy through radiator (19), for the usefulness of heating and baking footgear. Switch (K) with seal in again in the circuit after a diode (D) is in parallel, can only play energy-conserving action, can not play the on-off action of power supply. When being in the position of connection (namely opening) such as switch (K), electric current directly passes through from switch (K), heating (33) full power (35W) work, when not needing higher temperature, when switch (K) is in the position of disconnection (namely closing), electric current can not pass through from switch (K), and pass through through diode (D), because impedance and the unilateral conduction of diode, make through electric current reduce, the power consumption of heating (33) is lowered nearly half (reducing about 15W) work, thereby the heat of heating (33) is reduced, save electric energy, reduced consumption.

During use, external power supply plug (1) is inserted in the AC Power supply socket of 220V, it is plugged, indicator lamp (18) sends ruddiness, and the position that again power down switch (K) is placed out earlier is excessively after 5-6 minute, the heat that heating (33) produces, through the effect of radiator (19), conduction discharges, because the poly-temperature of thermal-arrest thermal cover (4) is done With, make the temperature of electric foot warmer be elevated to gradually certain limit, particularly the surface temperature of radiator (19) is higher and suitable, at this moment both feet need not take off one's shoes from the back door (9) stretch into, step on radiator (19), shut back door (9) and treated 5-7 minute, both feet begin warm warming up, temperature constant temperature has been realized the purpose of the antifreeze heating of foot in the electric foot warmer in about 25 degree. Can be according to the needs of temperature height, energy-saving adjusting switch (K), the temperature that just can obtain to suit during heating. During such as needs bakings footwear, socks, with wash wet footwear, socks are wrung out water, put into above the radiator (19) of electric foot warmer, can dry in several hours.

This utility model novel structure, elegant in appearance, it is easy to manufacture to draw materials, with ferrum, wood, mould, fiber product makes, cost is low, easy to use, safe and reliable, one device is dual-purpose, save electric energy, one month power consumption 4-5 degree, and the heating of personnel's foot and family's baking footgear of extensively be suitable for often being seated work, study use.
