## Background
TECHNICAL FIELD
The present invention relates to a cloth treating apparatus, and more particularly, to a cloth treating apparatus comprising an auxiliary treating apparatus which is provided in a main body, which performs washing and drying, to enable drying of objects of small quantity to be dried.
BACKGROUND ART
Generally, a cloth treating apparatus means an apparatus that can wash, dry, or both wash and dry clothes, etc. The cloth treating apparatus performs either a washing function or a drying function, or can perform both washing and drying functions. Also, a cloth treating apparatus having a steam supply device has spread recently, wherein the steam supply device performs a refresh function of clothes, etc., such as wrinkles removing, smell removing, and electrostatic removing.
Meanwhile, conventional cloth treating apparatuses are divided into a front loading type and a top loading type depending on a loading direction of clothes. Also, the cloth treating apparatuses are divided into a vertical type and a horizontal type depending on a washing type, wherein the vertical type includes a pulsator or an inner tub which is rotated, and the horizontal type includes a drum which is arranged horizontally and rotated. Examples of the horizontal type cloth treating apparatus include a drum washing machine and a drum dryer.
Recently, such cloth treating apparatuses are on a large-scaled trend to meet user's request. In other words, outer sizes of cloth treating apparatuses for home use are on a large-scaled trend.
In accordance with such a large-scaled trend, a large-scaled apparatus should be driven to dry objects of small quantity. In this case, a problem occurs in that it is disadvantageous in view of energy saving.
In case of a drum type dryer, since a drum is rotated to tumble objects to be dried, a problem occurs in that the drum type dryer is not suitable for drying of footwear, etc. Furthermore, it is general that footwear of small quantity such as a pair of footwear or two pairs of footwear is washed. In this way, when a conventional dryer is used to dry objects of small quantity, since a drum should be driven and a heater and a fan with high capacity should be driven, it is inefficient in view of energy.
In this respect, instead of the conventional large-scaled washing machine, a small-scaled dryer having capacity smaller than that of the large-scaled washing machine is required. However, it is not desirable in view of space use and a fine view that two washing machines are provided for each home even though one of the washing machines has a small scale.

Accordingly, it is preferable that the ventilating fan 232 is comprised of an intake fan which is formed at the inlet 231 and forcibly supplies the external air into the drawer 220.
Meanwhile, the heater 233 heats the air flowing through the ventilating fan 232 to supply the heated air into the drawer 220. The heater can be provided in various types. In the embodiment of the present invention, a sheath heater can be used as the heater 233. Since the sheath heater has durability robust to vibration and impact, regular heat distribution, and good insulating resistance, safety accident due to a short circuit can be prevented from occurring even though the hot air supply device 230 is formed inside the drawer 220, i.e., the space where the objects to be dried are received. Accordingly, the sheath heater is suitable for the auxiliary treating apparatus 200 according to the present invention.
Furthermore, according to another embodiment of the present invention, the heater 233 is a PTC heater, which is formed by powder molding of PTC elements. The PTC heater has a variable resistance property current value varied depending on temperature. Accordingly, as temperature increases, resistance increases, and a current flowing to the heater decreases. If the heater is normally operated, since its current value is very small, safety accident due to a leakage current is avoided even though a problem such as a short circuit occurs.
Such a PTC heater may be provided in plural numbers. If a fixed temperature heating effect of a plurality of PTC heaters is used, a temperature of the heater used during drying can be adjusted depending on the objects to be dried. In case of the objects to be dried, which are made of materials weak to heat, drying can be performed without damage of the objects. For example, a problem such as deformation in a rubber of footwear due to heat does not occur.
Meanwhile, the hot air supply device 230 according to the embodiment of the present invention may be provided with a thermostat which controls a temperature regularly. The thermostat (not shown) is made of bimetal by bonding two alloy plates having different linear expansion coefficients. In this case, a switch is opened and closed using a feature that a baking level of bimetal is varied depending on temperature change. This is to allow the power to be turned off automatically when the temperature becomes greater than a designated temperature due to the heater 233.
The heated air flowing through the ventilating fan 232 and passing through the heater 234 is exhausted into the drawer 220 through the outlet 234.
Meanwhile, it is preferable that a front end of the housing 236 where the outlet 234 is formed has an arc shape to exhaust the air passing thorough the hot air supply device 230 into the drawer 220 in a wide range. However, the front end of the housing 236 is not limited to such an arc shape, and it is to be understood that the front end of the housing 236 may have any shape which allows the air exhausted through the outlet 234 to be distributed into the drawer in a wide range.
Furthermore, it is preferable that the outlet 234 is provided with an air guide 235 which guides flow of the air to regularly distribute the air into the drawer 220. The air guide 235 is formed in such a manner that a plurality of air guides are spaced apart from one another along the shape of the outlet 234 to guide the flow of the air exhausted from the outlet 234. Accordingly, the air flowing in one direction through the ventilating fan 232 can be exhausted by being extended into the drawer 220 by the air guide 235.

The drying racks 226 and 227 can be used if necessary to arrange the objects to be dried thereon. The user adjusts a timer depending on types of the objects to be dried through the manipulation part 223, so as to start drying.
If drying starts, the hot air is forcibly supplied into the drawer 220, where the objects to be dried are received, through the hot air supply device 230. In other words, the air flows into the air supply device through the ventilating fan 232, and the flown air is heated by the heater 233 and then supplied into the drawer 220.
The air discharged from the hot air supply device 230 is extended and supplied into the drawer 220 along the air guide 235.
The air flowing into the drawer 220 dries the objects to be dried, and is exhausted out through the outlet 224. At this time, a smell generated during drying is removed by the filter 255 formed at the outlet 224.
Accordingly, if the time adjusted by the user ends through repeating the above procedure, the auxiliary treating apparatus 200 finishes the operation.
It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the invention.
