Abstract

The utility model relates to an electronic shoe dryer, which belongs to a household appliance. The utility model is composed of a housing which is composed of a bottom and a cover which are fastened tightly, a positive temperature coefficient thermistor heating element, two electrodes, two insulating strips, a timer, a conducting wire and a plug. Flaky electrodes which are used as radiation fins are welded or riveted with the conducting wire. The bottom and the cover are provided with air convection holes to accelerate heat radiation. The utility model has automatic temperature limitation, and the utility model does not have overheating to burn shoes or to cause the shoes to have aging. The utility model has safety, convenient use and low cost, and the utility model which can set time can be used for a family to dry the shoes.

Description

The electronics shoe baking device

The utility model relates to household electrical appliance, more clearly says so to be used in the family the electronics shoe baking device of footwear from interior oven dry.

Up to now, shoe baking device is at home and abroad all extensively promoted.In fact the artificial sweaty feet of great majority usually is moist in the footwear, and the wet footwear of dress are extremely uncomfortable, and infects and pedopathy because of bacteria breed causes various foots.Therefore, objectively see the shoe baking device extensive market.The reason of not applying is that existing shoe baking device has following shortcoming and defect: heater element is that resistance wire or resistive band and so on are made, can not temperature automatically controlled limit temperature, easily overheatedly make that footwear are aging to be out of shape or scaling loss, and dangerous; The cost height is difficult for accepting for the general masses; Do not have timing controlled, usually make baking footwear overlong time waste electric energy or too short not reaching of time give the phase effect, use inconvenience because of forgeing.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provide a kind of can A.T.C, can overheatedly not cause aging distortion of footwear or scaling loss, safe and reliable; With low cost, be easy to accept into common people; Timing controlled is arranged, electronics shoe baking device easy to use.

In order to achieve the above object, the utility model by shell, be installed in heater element in the shell, the lead of drawing in enclosure that links to each other with heater element constitutes.

Shell is formed so that securing member is fastening by the end and lid.Heater element is a semistor, and each links to each other its upper and lower surface with the plate electrode fin of holding concurrently.Between the electrode and the end and the lid with insulating trip insulation, wire bonds or be riveted on the electrode.

Semistor is the PTC element, and it has the characteristic of automatic limit temperature.When temperature reached curie point, its resistance increased rapidly and makes that power reduces rapidly, temperature is returned and fallen.For avoiding actual effective power too small, the electrode fin of holding concurrently is bigger, makes with aluminium sheet or copper coin.Simultaneously, the end, have the cross-ventilation hole with covering, so that heat is dissipated in baking footwear in the footwear as early as possible.The PTC element is with low cost, uses 1～4 and gets final product, and this just makes the utility model have lower cost, price also low.

The lead of drawing in enclosure links to each other with plug through timer.Installing timer additional can be electronic type, also can be mechanical, as the timer of small electric fan.After installing timer additional, baking can be set the footwear time as required, as 20 minutes, 40 minutes, 1 hour, 2 hours or the like.Both can guarantee footwear oven dry, and can avoid overlong time to cause wear out distortion, scaling loss or expense of footwear electric, very convenient again.

Task of the present utility model comes to this and finishes.

The utility model provide a kind of can be temperature automatically controlled the limit temperature, safe and reliable; Cost is low, be easy to popularize; Can in time dehumidifying drying in the footwear be increased comfortableness and reduce the pedopathy infection; Can regularly dry, electronics shoe baking device easy to use.Compare with the like product in past, its cost has reduced by 30～60%, and security improves 1～3 times.It can be widely used in the places such as family, hotel, enterprise, hospital.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.

Fig. 1 is the general structure schematic diagram of embodiment 1.

Fig. 2 is the resistance-temperature characteristics figure of PTC element.

Fig. 3 is the schematic diagram of the timer of embodiment 2.

Shown in Figure 1, embodiment 1 is made of the fin 5 of holding concurrently with the end 1, lid 2 and securing member 3 shell, PTC heater element 4, the pellet electrode formed, insulating trip 6, lead 7.All have cross-ventilation hole 8 on the end 1 and the lid 2.

Shown in Figure 2, the PTC heater element is after temperature reaches curie point, and resistance rises rapidly, power descends rapidly.

Shown in Figure 3, the timer of embodiment 2 is a kind of electronic timer.Adopt the accurate level detection circuit of 2 CA3096 dual inputs.

Embodiment 1 and 2 is easy to use, safe and reliable, and cost reduces by 60% more in the past, can be widely used in the places such as family, hotel, hospital, factory.
