## Background
The current application claims the benefit of IL Patent application no. 199710, filed 6 Jul. 2009, incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to the field of home appliances. More particularly, the invention relates to a shoe dryer.
BACKGROUND OF THE INVENTION
Shoes tend to get wet during outings on rainy or snowy days. This problem is acute particularly in countries regularly featuring rain, snow and sleet, ski sites, and so on. Since the drying process may require several hours, sometimes even the entire day, it is desirable for more rapid drying, particularly when the user needs to go outdoors again soon.
U.S. Pat. No. 5,016,364 to Cochrane discloses a drying apparatus that utilizes air circulation to uniformly dry articles. The apparatus includes an enclosure having racks upon which the articles to be dried are placed. An air exchanger couples to the enclosure to recirculate and heat air within the enclosure. Recirculation operates continuously while articles are being dried, and recirculation air temperature is maintained around a predetermined level through a thermostat coupled to heating elements. The air exchanger is configured so that air expelled from the air exchanger travels upward near the enclosure's walls, then downward in the center of the enclosure back to the air exchanger. An exhaust fan is controlled by a humidistat to remove humid air from the enclosure whenever the humidity within the enclosure exceeds a predetermined level. Consequently, a mean humidity level is maintained within the enclosure to prevent excessive drying, and substantial recirculation of air results in improved efficiency.
One drawback of the disclosure of Cochrane is that the entire enclosure is heated, which results in energy waste if the enclosure is not fully occupied.
It is an object of the present invention to provide a shoe dryer which overcomes the above-mentioned and other problems of the prior art.
It is a further object of the present invention to provide a comprehensive solution to shoe drying.
Other objects and advantages of the invention will become apparent as the description proceeds.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The present invention will be understood from the following detailed description of preferred embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.
FIG. 1 is a perspective view that schematically illustrates a shoe dryer, according to one embodiment of the invention.
The shoe dryer, which is marked herein as reference numeral 10, is designed in the form of a chair/stool, thereby allowing a user to sit thereon when taking his shoes off or putting his shoes on.
The seat of the chair, which is marked by reference numeral 14, may be filled with padding, thereby allowing comfortable seating thereon.
The shoe dryer may further comprise arms 12, a back support, and so on, in order to enhance seat comfort. Actually, a user may sit on the chair while drying his shoes.
In the embodiment illustrated herein, the enclosure is a structure in the form of a closed box 16 having an inlet 22 and outlets 18.
A user may adjust the drying time by knob 24, and the scale thereof, 26.
Reference numeral 20 is a rack installed at the bottom of box 16, for collecting mud from drying shoes. Preferably, rack 20 is pullable.
FIG. 2 is a perspective view that schematically illustrates the shoe dryer of FIG. 1 in a situation wherein the seat thereof is lifted up.
FIG. 3 is a broken view of FIG. 2, which further details the inner parts of the dryer.
The top of the box (i.e., seat 14) is connected at one edge thereof, by an axle (not illustrated), to the upper back edge of box 16 of the dryer. Thus, seat 14 is also used as a cover to box 16.
A pair of strings 34 connect seat 14 to a grid 36, on which drying shoes are placed. Grid 36 is movable up and down along vertical rails 38. Upon lifting seat 14, i.e., upon opening cover 14, strings 34, which connect seat 14 to a grid 36, pull the grid upwards. Upon placing seat 14 back, i.e., upon closing cover 14, the gravity pulls grid 36 down into box 16. This mechanism facilitates the use of the shoe dryer for a disabled user.
The drying process includes conveying heated air through pipes 30, into shoes 28.
FIG. 4 schematically illustrates a drying mechanism of a shoe dryer, according to one embodiment of the invention.
The drying mechanism comprises three systems:

    
    
        a heating system that heats air;
        
            a conveying system that conveys the heated air into the interior side of the shoes to be dried; and
            a control system that controls the time period of the heating process.

The mechanism operates as follows:

        
        
    
    


A propeller 42 propels air from outside of box 16, through heating body 40, into pipe 50, which splits into flexible pipes 30. The end of each pipe 30 is directed into the interior side of the shoes 28 to be dried. This can be carried out by attaching a clamp 32 to the end of a pipe 30. The clamp allows placing the end of pipe 30 such that heated air passing out of this end is directed into the interior side of a shoe.
Control system 44 controls the heating process. The duration of the heating process is determined by a timer, the knob of which is marked herein by reference numeral 24. The heated air directed into the shoes spreads out of the shoes, heating the entire enclosure of the box, thereby allowing drying of other wet wear, such as gloves.
According to this embodiment of the invention, the heating system is connected by bolts (not illustrated) through bores 48 to the walls of box 16. At the end of each of pipes 30 is installed a clamp 32 (clip, hook, and the like), which connects the end of pipe 30 to grid 36. In addition, pipes 30 are flexible. This allows moving grid 36 up and down, while the end of pipe 30 is connected to the grid, thereby continuing the drying process of the shoe thereof.
As illustrated, pipe 50 splits into a pair of pipes 30. However, it should be noted that the pair of pipes 30 is merely an example, and pipe 50 may split into other number of pipes, such as three pairs.
Of course, the illustrations and description herein present an example of a design, and those skilled in the art will appreciate that other designs may be used for achieving the same objects.
