Description

Warm footwear plate temperature adjuster

Technical field

The invention belongs to electronics and temperature control technology field, relate to a kind of warm footwear plate temperature adjuster.

Background technology

Run into overcast and rainy, cloudy weather for several days running sky or sleet sky, once the shoes of wearing are got wet, especially child wades acroos a river drenched shoes, just very uncomfortable if wet footwear are worn for second day again.The products such as the various shoe baking devices sold on market, shoe drier, shoe baking device, warm footwear device, they without exception be all two first halves (front portions of footwear) that respectively insert respectively footwear with a wire shoe baking device, if shoes are all got wet, the latter half of basic baking of shoes less than, more worried is that it once can only toast a pair of shoes, household's wet footwear toast nowhere, do not reach the requirement for many pairs of shoes dehumidifying simultaneously.In addition, the operation and maintenance of shoe baking device is also problem, will pay special attention to prevent that dust or foreign material from blocking the louvre of shoe baking device, otherwise the shoe baking device evolution of heat is enclosed in shoe baking device when use, thereby cause warm footwear effect to be had a greatly reduced quality, and easily bury accident potential.

Warm footwear plate temperature adjuster of the present invention, it changes the baking footwear pattern of traditional shoe baking device, it is that heating wire is laid on an insulation board, regulated the surface temperature of warm footwear plate by thermoregulator, warm footwear plate can toast more than four pairs shoes simultaneously, no matter which kind of footwear type all can reach best warm footwear and effect on moisture extraction, whole family adult, child all can enjoy, and very easy to use.

Especially in the winter time or sleet sky use, shoes toast a night in evening, morning dress is dry and comfortable warm again! It is cool to those pin, the crowd's foot of easily getting chilblains has good health-care effect.In addition, warm footwear plate also has the effect such as deodorizing, sterilization.

Below describe warm footwear plate temperature adjuster of the present invention related relevant technologies content in manufacturing process in detail.

Summary of the invention

Goal of the invention and beneficial effect: warm footwear plate temperature adjuster of the present invention, it changes the baking footwear pattern of traditional shoe baking device, it is that heating wire is laid on an insulation board, regulated the surface temperature of warm footwear plate by thermoregulator, warm footwear plate can toast more than four pairs shoes simultaneously, no matter which kind of footwear type all can reach best warm footwear and effect on moisture extraction, whole family adult, child all can enjoy, and very easy to use.Especially in the winter time or sleet sky use, shoes toast a night in evening, morning dress is dry and comfortable warm again! It is cool to those pin, the crowd's foot of easily getting chilblains has good health-care effect.In addition, warm footwear plate also has the effect such as deodorizing, sterilization.

Circuit working principle: the core of warm footwear plate temperature adjuster is a bistable circuit.220V AC power, through decompression capacitor C1, bleeder resistance R1 step-down current limliting, through silicon rectifier diode D1 rectification, and obtains the required 12V burning voltage of circuit working through electrochemical capacitor C3 filtering and Zener diode DW voltage stabilizing.

When thermoregulator circuit is connected after 220V AC power, because the 2nd pin and the 6th pin of time base circuit IC1 are low level, make time base circuit IC1 in triggering set, at this moment the 3rd pin of time base circuit IC1 is high level, now the coil of DC relay J obtains electric normally opened contact J-1 in on-state, and heating wire must be established the heating of beginning by cable.When electric current charges to timing capacitor C2 through resistance R 2, along with the increase in charging interval,

When the voltage at timing capacitor C2 two ends rises to 2/3 supply voltage, time base circuit IC1 automatically resets, make the 3rd pin of time base circuit IC1 become low level, the DC relay J coil that the 3rd pin of time base circuit IC1 connects discharges normally opened contact J-1 is disconnected without electricity, and heating wire disconnects 220V AC power and stops heating.Because the 3rd pin of time base circuit IC1 is low level, the threshold voltage of time base circuit IC1 is not 1/3 supply voltage, now timing capacitor C2 passes through 7th pin of linear potentiometer RP by time base circuit IC1, discharge by internal discharge pipe, the voltage drop that always discharges into timing capacitor C2 is during to 1/3 supply voltage, time base circuit IC1 set again, makes the 3rd pin of time base circuit IC1 become again high level.Suitably the resistance of linear adjustment potentiometer RP, can make the heat time of heating wire, the heat time of stopping be controlled at respectively 2～10 minutes, regulates thereby realize temperature.
