- the steam dryer of the present invention include an indicater for indicating a water level of the water in the lower housing 310 . Then, the user can notice the water level of the water in the lower housing 310 , to supply an appropriate amount of water to the lower housing 310 .
- the appropriate amount is an amount of water that can be filled in the water container 300 , i.e., an amount of water that can be received by the lower housing 310 , which varies with a capacity of the steam generator, or a size of the water container 300 .
- the indicator includes a transparent part 360 of the water container 300 so that the water level is seen through the transparent part 360 .
- the transparent part 360 may be formed in a height direction of the water container 300 , i.e., the lower housing 310 at a side thereof. It is preferable that the transparent part 360 is formed of a transparent material. Then, when the user supplies water to the lower housing 310 , the user can make easy notice of the water level being filled in the lower housing 310 with the transparent part 360 . More preferably, the transparent part 360 may further include a color varying material that varies a color thereof with a temperature. Then, since the color varying material varies a color thereof with a temperature of the water as the water is being filled in the lower housing 310 , the user can make easy notice of the water level being filled in the lower housing 310 .
- the water container 300 further include an indicating line 361 that indicates the water is filled up to the appropriate water level of the lower housing 310 at the time the water supplied to the water container 300 .
- the appropriate water level is a water level when an appropriate amount of water that can be held in the lower housing 310 , i.e., an appropriate amount, is filled, which can vary with the capacity of the steam generator, or the size of the water container 300 . According to this, when the water is supplied to the water container 300 , the user can control such that the appropriate amount of water is supplied to the lower housing 310 by means of the transparent part 360 and the indicating line 361 .
- the indicating line 361 may be formed on the transparent part 360 or on the lower housing 360 in the vicinity of the transparent part 360 .
- the indicating line 361 may include a plurality of gradation lines for indicating, not only the appropriate water level of the lower housing 310 , but also indicating the water level in detail.
- FIG. 6 illustrates a perspective view of a second embodiment of the water container in FIG. 4
- FIG. 7 illustrates a section across a line II-II in FIG. 6 , showing the water filled up to the appropriate level of the lower housing 310 , schematically. Since the water container 300 of the second embodiment is different from the foregoing embodiment only in the transparent part 360 , reference numerals and description of the second embodiment on portions other than the indicator 360 will be the same with the foregoing embodiment.
- the transparent part 360 of the embodiment is formed on one side of an upper surface of the water container 300 , i.e., one side of an upper surface of the upper housing 320 . It is preferable that the transparent part 360 is formed of a transparent material. Then, the user can make easy notice of the water level being filled in the lower housing 310 . Particularly, in general, the user supplies the water to the water container 300 , standing on a floor, when the user can make easy notice of the water level being filled in the water container 300 even in the standing state as the transparent part 360 is formed in the upper surface of the water container 300 . That is, if the transparent part 360 is formed at the side of the water container 300 the same as the embodiment shown in FIG. 5 , though there is inconvenience of the user to bend body to notice the water level, the embodiment enables the user to notice the water level being filled in the water container 300 even in the standing state.
- the transparent part 360 may be recessed. More preferably, the transparent part 360 may be recessed such that a width thereof becomes the smaller as the recess goes the deeper. Then, the user can make easier notice of the water level being filled in the water container 300 in the standing state. That is, if the transparent part 360 is recessed down with a fixed width, the user can not make easy notice of the water level when the user looks down the transparent part 360 right over the transparent part 360 . But, if the width of the water container 300 becomes the smaller as shown in FIG. 7 , the user can make easy notice of the water level when the user looks down the transparent part 360 right over the transparent part 360 . In this instance, the indicating line 361 that indicates the appropriate water level of the lower housing 310 can be formed around the transparent part 360 .
- the transparent part 360 further includes a color varying member that varies a color with a temperature. Then, since the color varying member varies a color thereof with a temperature of the water as the water is being filled in the lower housing 310 , the user can make easy notice of the water level being filled in the lower housing 310 .
- the color varying member may further included only to a bottom surface of the lower housing 310 . In this case, it is preferable that the indicator 363 is recessed down to the appropriate water level of the lower housing 310 . Then, if the water is filled to the appropriate water level of the lower housing 310 , filling up the water to the bottom surface of the lower housing, the color of the color varying member can be varied.
- the user can make easy notice of the water filled up to the appropriate water level of the lower housing 310 .
- formation of the indicating line 361 is not required, as the color varying member serves as the indicating line 361 .
- FIGS. 8 to 10 each illustrates a diagram of a third embodiment of the water container in FIG. 4 , wherein FIG. 8 illustrates a state the water is not filled up to the appropriate water level of the water container schematically, FIG. 9 illustrates a state the water is filled up to the appropriate water level of the water container schematically, and FIG. 10 illustrates a circuit diagram of a sensor, schematically. Since the water container 300 of the third embodiment is different from the foregoing embodiment only in that the sensor 370 is provided instead of the transparent part 360 in the first and second embodiment, reference numerals and description of the first and second embodiment on portions other than the transparent part 360 will be the same with the second embodiment.
- the indicator of the embodiment includes a sensor 370 for sensing the water level of the lower housing 310 .
- the sensor 370 includes a power source unit 371 provided to a predetermined location of the lower housing 310 , and a first electrode 372 and a second electrode 373 connected to the power source unit 371 . It is preferable that the first electrode 372 and the second electrode 373 is spaced from each other such that the first electrode 372 and the second electrode 373 are connected to the water located to water levels of the lower housing 310 different from each other.
- the first electrode 372 is connected to the water located at a higher water level than the second electrode 373 .
- the second electrode 373 may be connected to the water located at a higher water level than the first electrode 372 . Then, as shown in FIG. 9 , if the water filled in the lower housing 310 reaches to the water level connected to the first electrode 372 , a minute current flows between the first electrode 372 and the second electrode 373 through the water filled in the lower housing 310 , to make the sensor 370 in conduction.
- the indicator of the embodiment further includes a signal creating part 374 for creating a predetermined signal once the sensor 370 becomes in conduction.
- a signal creating part 374 for creating a predetermined signal once the sensor 370 becomes in conduction.
- the user can make easy notice of the signal from the signal creating part 374 .
- the first electrode 372 may be mounted so as to be connected to the water located at the appropriate water level of the lower housing 310
- the second electrode 373 may be mounted so as to be connected to the water located under the appropriate water level. Then, when the water is supplied to the lower housing 310 , the user can make easy notice of the water being filled to the appropriate water level of the lower housing 310 by means of the signal creating part 374 .

Description
- The present invention relates to laundry machines. More specifically, the present invention relates to a laundry machine for removing creases or crumples from, or preventing the same from forming on, clothes.
- In general, in the laundry machines, there are machines for washing, drying, or clothes. In the refreshing of the clothes, moisture, creases, crumples, static electricity, or odor is removed from the clothes, or aroma is added to the clothes.
- In the laundry machines, there are washing machines and dryers, wherein the dryer is in general a home appliance for drying washed laundry, mostly clothes, with hot air. In general, the dryer is provided with a drum for holding a drying object, a driving source for driving the drum, heating means for heating the air introduced to the drum, and a blower unit for drawing or discharging the air from/to the drum.
- Depending on means for heating the air, i.e., the heating means, there can be electric type dryers and gas type dryers. The electric dryer heat the air with electric resistance heat, and the gas type dryer heats the air with heat from burning the gas. The dryers may be sorted in another way, i.e., condensing type dryers, and exhaust type dryer. The condensing type dryer does not discharge the humid air heat exchanged with the drying object in the drum to an outside of the dryer, but circulates the humid air in the dryer, and makes the humid air to heat exchange with external air at a condenser provided separately to discharge condensed water formed thus to the outside of the dryer. The exhaust type dryer discharges the humid air heat exchanged with the drying object in the drum to the outside of the dryer directly. Depending on a type for introducing the laundry to the dryer, the dryer may be sorted top loading type dryers and front loading type dryers. In the top loading type dryers, the drying object is introduced to a top side of the dryer, and in the front loading type dryers, the drying object is introduced to a front of the dryer.
- However, the related art laundry machine has the following problems.
- In general, the dryer dries washed and water extracted laundry introduced thereto. However, in view of a principle of water washing, creases are formed on the washed laundry, and the creases formed thus can not be removed perfectly in the drying process. Consequently, in order to remove the creases from the drying object, such as laundry dried in the related art dryer, additional pressing is required.
- Moreover, besides the washed laundry, in a case of conventional storage, and use of clothes, creases, crumples, folds and so on (will be called as creases collectively) take place. Development of an appliance for easy removal of such creases caused by conventional storage and use of clothes has been required.
- To solve the problem, an object of the present invention is to provide a laundry machine which can prevent crease from forming on clothes, and/or removing the crease from the clothes.
- Another object of the present invention is to provide a laundry machine which enables a user to make easy notice of a water level of water held in a water container during water supply or operation of the laundry machine.
- To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a laundry machine comprises a drum to be selectively rotatable; a steam generator to generate steam to be supplied to the drum; a water container to contain water to be supplied to the steam generator; and an indicator to indicate a level of the water in the water container.
- The indicator includes a transparent part of the water container so that the water level is seen through the transparent part or a sensor to sense the water level or the water container includes a supply hole through which water is supplied, and the indicator includes a closing member to close the supply hole when the water in the water container reaches a predetermined water level.
- The present invention has following advantageous effects.
- First, the washing machine of the present invention prevents crumples or creases from forming on, or removes the same from a drying object effectively, and sterilizes the drying object or remove odor from the drying object.
- Second, the washing machine of the present invention can remove crumples or creases from dried clothes without separate pressing effectively.
- Third, the washing machine of the present invention permits, not only easy supply of water to the waster holding unit, but also easy cleaning of the water container. Moreover, the washing machine of the present invention permits easy notice of the water level held in the water container during water supply or operation of the washing machine.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
- In order to describe a laundry machine of the present invention, a steam dryer will be described as an embodiment of the present invention. However, the present invention is applicable to, for an example, a washing machine with steam.
- Moreover, in order to described the steam dryer which is an embodiment of the present invention, a top loading, electric, condensing type steam dryer will be described as one embodiment in view of convenience of description. However, the present invention is not limited to this, but is applicable to a front loading, gas, condensing type steam dryer, too.
- The steam dryer of the present invention will be described with reference to
FIGS. 1 and 2 . - Inside of a
cabinet 10 which forms an exterior of the steam dryer, there are arotatable drum 20, amotor 70 and abelt 68 for driving thedrum 20. Mounted at a predetermined location of thecabinet 10, there are a heater 90 (will be called as hot air heater) for heating air to produce high temperature air (will be called as hot air), and a hotair supply duct 44 for supplying the hot air from thehot air heater 90 to thedrum 20. And, anexhaust duct 80 for discharging humid air heat exchanged with the clothes at thedrum 20 and ablower unit 60 for drawing in the humid air are also mounted. In the meantime, mounted at a predetermined location of thecabinet 10, there is asteam generator 200 for generating hot steam. For convenience sake, though the embodiment shows and describes based on an indirect drive type in which thedrum 20 is rotated by using themotor 70 and thebelt 68, the present invention is not limited to this. That is, the present invention is also applicable to a direct drive type in which thedrum 20 is rotated directly by a motor directly connected to a rear of thedrum 20. - Respective elements of the dryer will be described in detail.
- The
cabinet 10 which forms an exterior of the steam dryer includes abase 12 which forms a bottom of the steam dryer, one pair ofside covers 14 mounted to thebase 12 vertically, afront cover 16 and arear cover 18 mounted to a front and a rear of theside covers 14 respectively, and atop cover 17 located on top of the side covers 4. Acontrol panel 19 with various operation switches is located on thetop cover 17 or thefront cover 16 conventionally, and adoor 164 is mounted to thefront cover 16. Therear cover 18 has aninlet 182 for introduction of external air, and anexhaust hole 184 which is a final passage for discharging the air from thedrum 20 to an outside of the steam dryer. - An inside space of the
drum 20 serves as a drying chamber for drying the clothes, and, it is preferable that lifts 22 are provided to an inside of thedrum 20 for lifting and dropping clothes, to turn the clothes upside down for enhancing drying efficiency. - In the meantime, mounted between the
drum 20 and the cabinet 10 (thefront cover 16 and the rear cover 18), there are afront supporter 30 and arear supporter 40. Rotatably mounted between thefront supporter 30 and therear supporter 40, there is thedrum 20, and mounted between thefront supporter 30 and therear supporter 40 and thedrum 20, there are sealing members (not shown) for preventing leakage. That is, thefront supporter 30 and therear supporter 40 cover the front and rear of thedrum 20 to form the drying chamber, and support the front and rear of thedrum 20, respectively. - The
front supporter 30 has an opening to make thedrum 20 to be in communication with an outside of the dryer, which is opened/closed with thedoor 164 selective. Thefront supporter 30 also has alint duct 50 connected thereto, which is a passage of the air from thedrum 20 to an outside of the dryer, with alint filter 52 mounted thereto. Theblower unit 60 has one side connected to thelint duct 50, and the other side connected to theexhaust duct 80 which is connected to theexhaust hole 184 in therear cover 18. Accordingly, if theblower unit 60 is in operation, the air is discharged to an outside of the dryer from thedrum 20 through thelint duct 50, theexhaust duct 80, and theexhaust hole 184. In this instance, foreign matters, such as lint, are filtered at thelint filter 52. In general, theblower unit 60 includes ablower 62 and ablower housing 64, and, in general, theblower 64 is driven by themotor 70 which also drives thedrum 20. - The
rear supporter 40 has an openingportion 42 having, in general, a plurality of pass through holes, with the hotair supply duct 44 connected thereto. The hotair supply duct 44 is in communication with thedrum 20 for serving as a passage for supplying the hot air to thedrum 20. Accordingly, thehot air heater 90 is mounted to a predetermined location of the hotair supply duct 44. - In the meantime, mounted to a predetermined location of the
cabinet 10, there is thesteam generator 200 for generating and supplying steam to thedrum 20. Thesteam generator 200 will be described in detail with reference toFIG. 3 . - Mounted in the
steam generator 200, there are awater tank 210 for holding water, aheater 240 mounted to an inside of thewater tank 210, awater level sensor 260 for measuring a water level of thesteam generator 200, and atemperature sensor 270 for measuring a temperature of thesteam generator 200. In general, thewater level sensor 260 includes acommon electrode 262, a lowwater level electrode 264, and a highwater level electrode 266 for sensing a high water level or a low water level depending on electric conduction between thecommon electrode 262 and the highwater level electrode 264 or thecommon electrode 262 and the lowwater level electrode 266. - The
steam generator 200 has one side connected to awater supply hose 220 for supplying water, and the other side connected to asteam hose 230 for discharging steam, and it is preferable that a predetermined shape ofnozzle 250 is provided to a fore end of thesteam hose 230. - In the meantime, though the embodiment shows and describes a steam generator 200 (will be called as a tank heating type for convenience sake) of a type in which a predetermined amount of water held in the
water tank 210 is heated with theheater 240 to generate the steam, the present invention is not limited to this. That is, the present invention can use any steam generator as far as the device can generate the steam. For an example, a configuration may also be used, in which a heater is mounted around a water supply hose through which water passes for heating the water without holding the water within a space (for convenience sake, will be called as tubular heating system). -
FIG. 4 illustrates a diagram focused on a steam generator of the present invention. - The water container which supplies water to the steam generator will be described with reference to
FIG. 4 . Though the steam generator illustrated inFIG. 4 is different in shape from the steam generator illustrated inFIG. 3 , the inventive step of the present invention is nothing to do with the shape of the steam generator, the steam generator inFIG. 4 can be the steam generator inFIG. 3 , and the same reference numerals will be used. - Referring to
FIG. 4 , in the embodiment, the steam dryer includes awater container 300 for supplying water to thesteam generator 200. It is preferable that thewater container 300 is detachable. That is, it is convenient if thedetachable water container 300 is detached in supplying water, and thewater container 300 filled with the water is connected to the water supply flow passage of thesteam generator 200, i.e., thewater supply hose 220 the same as the embodiment. - It is preferable that there is a
pump 400 mounted between thewater container 300 and thesteam generator 200. As a water outlet (not shown) of thewater container 300 is placed in aconnection hole 480, thepump 400 is connected to thewater container 300, and is connected to thesteam generator 200 with thewater supply hose 220. - It is more preferable that the
pump 400 is reversible, for supplying the water to thesteam generator 200, and if necessary, recovering remained water from thesteam generator 200. It is also possible that the water is supplied to thesteam generator 200 by using a water head between thewater container 300 and thesteam generator 200 without using the pump. However, because, in general, components of the dryer are standard goods of compact design, there are shortages of structural spaces, absolutely. Therefore, if sizes of the components of the related art dryer are not changed, the water supply by using the water head is impossible, actually. Accordingly, as use of a smallsized pump 400 enables mounting of thesteam generator 200 without changing the sizes of the components, use of thepump 400 is very favorable. The remained water is recovered from thesteam generator 200 for preventing the heater suffering from damage caused by the water if thesteam generator 200 is left unused for a long time, and preventing use of rotten water, later. - Though the foregoing embodiment shows water supply to, and steam discharge from a top side of the
steam generator 200, in the embodiment, it is preferable that the water is supplied to an underside of thesteam generator 200 and the steam is discharged from the top of thesteam generator 200. This configuration is favorable for recovering the remained water from thesteam generator 200. - It is preferable that a
safety valve 500 is provided to the steam flow passage, i.e., thesteam hose 230, which discharges steam from thesteam generator 200. -

FIG. 5 , thewater container 300 includes alower housing 310 for holding water actually, and anupper housing 320 detachable from thelower housing 310. Thelower housing 310 has awater discharge hole 302 at one side of an inside for connection to theconnection hole 480. There may be a filter at thewater discharge hole 302. - The
water container 300 with thelower housing 310 and theupper housing 320 enables easy cleaning of fur on an inside of thewater container 300, and easy dismounting and cleaning of the filter. Preferably, theupper housing 320 is detachable such that one side of thelower housing 310 is opened fully. Then, the user can make easier cleaning of the inside of thewater container 300. - The
water container 300 has afastening portion 330 for making the upper housing detachable from thelower housing 310. Thefastening portion 330 includes anextension 332 from one side of theupper housing 320 having ahole 333 at a center, and aholder 331 projected from one side of thelower housing 310 for placing in thehole 333. As the user makes theholder 331 to be placed in thehole 333, theupper housing 320 is fastened to thelower housing 320 easily. - It is preferable that the
water container 300 further includes asupply hole 321 in theupper housing 320 for supplying water, and acover 340 for opening/closing thesupply hole 321. Then, in a case water is supplied to thelower housing 310, the user can supply water to thesupply hole 321 conveniently after opening thecover 340 without dismounting theupper housing 320 from thelower housing 310. - It is preferable that the
water container 300 further includes ahinge portion 350 so that thecover 340 is rotatably secured to theupper housing 320. Then, the user can make easier opening/closing of thesupply hole 321 by rotating thecover 340. Thehinge portion 350 may include one pair ofhinge shafts 351 projected outwardly from one side of opposite sides of thecover 340 respectively, and hingeholes 352 in theupper housing 320 such that the one pair of thehinge shafts 351 are rotatably placed therein. - It is preferable that the steam dryer of the present invention include an indicater for indicating a water level of the water in the
lower housing 310. Then, the user can notice the water level of the water in thelower housing 310, to supply an appropriate amount of water to thelower housing 310. In this instance, the appropriate amount is an amount of water that can be filled in thewater container 300, i.e., an amount of water that can be received by thelower housing 310, which varies with a capacity of the steam generator, or a size of thewater container 300. - In the embodiment, the indicator includes a
transparent part 360 of thewater container 300 so that the water level is seen through thetransparent part 360. - The
transparent part 360 may be formed in a height direction of thewater container 300, i.e., thelower housing 310 at a side thereof. It is preferable that thetransparent part 360 is formed of a transparent material. Then, when the user supplies water to thelower housing 310, the user can make easy notice of the water level being filled in thelower housing 310 with thetransparent part 360. More preferably, thetransparent part 360 may further include a color varying material that varies a color thereof with a temperature. Then, since the color varying material varies a color thereof with a temperature of the water as the water is being filled in thelower housing 310, the user can make easy notice of the water level being filled in thelower housing 310. - It is preferable that the
water container 300 further include an indicatingline 361 that indicates the water is filled up to the appropriate water level of thelower housing 310 at the time the water supplied to thewater container 300. In this instance, the appropriate water level is a water level when an appropriate amount of water that can be held in thelower housing 310, i.e., an appropriate amount, is filled, which can vary with the capacity of the steam generator, or the size of thewater container 300. According to this, when the water is supplied to thewater container 300, the user can control such that the appropriate amount of water is supplied to thelower housing 310 by means of thetransparent part 360 and the indicatingline 361. The indicatingline 361 may be formed on thetransparent part 360 or on thelower housing 360 in the vicinity of thetransparent part 360. Preferably, the indicatingline 361 may include a plurality of gradation lines for indicating, not only the appropriate water level of thelower housing 310, but also indicating the water level in detail. -

lower housing 310 is higher than the insufficient water level, thefirst stick 381 and thesecond stick 382 become in conduction with each other by the water, to let thefirst electrode 375 and thesecond electrode 376 in conduction. As shown inFIG. 13 , if the water level is lower than the insufficient water level, to let thefirst stick 381 and thesecond stick 392 not in conduction, thefirst electrode 375 and thesecond electrode 376 are not in conduction, leading thesignal creating part 377 to create the signal for the user to notice. - The embodiment has an advantage in that mounting locations of the
first electrode 375 and thesecond electrode 376 are restricted less than before by the inclusion of thefirst stick 381 and thesecond stick 382. That is, thefirst electrode 375 and thesecond electrode 376 can be mounted to an upper portion or a lower portion of thelower housing 310 because thefirst electrode 375 and thesecond electrode 376 can work as far as thefirst electrode 375 and thesecond electrode 376 are conductive with thefirst stick 381 and thesecond stick 382 elongated in the height direction of thelower housing 310. This is convenient when thefirst electrode 375 and thesecond electrode 376 are connected to the power source of the steam dryer body when the water container is mounted to the steam dryer body. -
