Abstract
Disclosed hereinafter is a laundry device. More particularly, a washing machine comprises a steam generation unit installed therein to generate and supply steam to an outside of the washing machine or to a laundry-receiving device to remove wrinkles on laundry by using the steam supplied from the steam generation unit, and a method for controlling operation thereof. A method for controlling the washing machine is also disclosed. The washing machine comprises a steam generation unit to generate steam, and an steam outside-supplying pipe connected with the steam generation unit to supply the steam to an outside of the washing machine.
Description
- The present invention relates to a laundry device, and more particularly, to a washing machine which comprises a steam generation unit installed therein to generate and supply steam to an outside of the washing machine or to a laundry-receiving device to remove wrinkles on laundry using the steam supplied from the steam generation unit, and a method for controlling the same.
- Generally, a washing apparatus is an apparatus to perform various operations related to laundry, and includes a washing machine to wash the laundry, a drying machine to dry wet laundry, and the like.
- The drying machine has a problem in that, since it is operated in a state wherein various kinds of laundry are collectively input thereto, entangled laundry cannot be efficiently dried.
- In addition, when laundry is stored for a long period of time in such a conventional drying machine, wrinkles are severely created on the clothes, inevitably causing inconvenience of ironing. Thus, it is impossible for the conventional drying machine to store the laundry therein.
- Recently, it is needed to provide an improved drying machine which has an enlarged drying capacity while enabling the laundry to be stored for a long period of time therein. In this regard, combination type drying machines disclosed in US Patent Application Publication Nos. US 2004-0194339 A1 and US 2004-0154194 A1 comprise a separate drying cabinet in a drum type drying machine.
- The combination type drying machine as described above is a drying apparatus, which is constituted by combining a general drum type drying machine having a rotational drum, and a drying cabinet mounted on the drying machine such that hot wind is supplied thereto, and having a space for receiving various kinds of laundry.
- The drying cabinet is supplied with hot wind from the drum type drying machine, and uses the hot wind to dry or store the laundry therein for a long period of time.
- However, since the drying cabinet of the combination type drying machine is mounted on the drum type drying machine, it is necessary to limit the height of the drying cabinet. Thus, it is difficult for the drying cabinet to receive the laundry in a hung state, as such the drying cabinet must be implemented using shelves.
- Of course, the drum type drying machine described above is provided with a separate space to receive long laundry.
- However, since the space must be formed in such a manner that the space is depressed into an inner space at one side of the drum type drying machine, the drum type drying machine has a problem in that it has a substantially increased width in a longitudinal direction.
- In addition, since typical drum type washing machines (for example, drum type washing machine, a drum type drying machine, etc.) have a low height, they are used with its bottom supported by a separate support.
- However, in this case, the space of the washing machine is wasted by a height of the support.
- Of course, it has been suggested in the prior art to employ an inner space of the support as an accommodation space.
- However, since the accommodation space is not frequently used, it has a low effectiveness.
- In addition, an apparatus has not been developed in the prior art, which can realize a water washing effect for previously worn clothes via a simple operation course even when washing the once worn clothes without using water. Thus, if a user wants to wear neat laundry, it is necessary to iron the laundry, causing inconvenience and the user to be dissatisfied. If the laundry is dried in the conventional drying machine, the laundry is seriously wrinkled in the drying machine, thereby requiring troublesome ironing operation on the laundry.
- Furthermore, in the prior art, there is no such an apparatus which employs steam in order to realize the water washing effect for the once worn clothes.
- Thus, there is a need to provide an apparatus, which can perform water washing in the case where the laundry are very dirty, and can realize the water washing effect via a simple operation course using the steam in the case where the laundry is not seriously soiled and do not require the water washing.
- An object of the present invention devised to solve the problem lies on an improved washing machine, which employs steam to remove wrinkles on laundry while providing sterilization effect to the laundry.
- Another object of the present invention is to provide the washing machine, which comprises a refresh part only to perform refresh operation for the laundry, and selectively supplies the steam to the refresh part or to a drum in which washing (or drying) operation is performed.
- Further object of the present invention is to provide the washing machine, which can supply the steam to an external device such as a laundry-refreshing device, which is separately installed at the outside. Since a user can employ a steam generation unit in the washing machine for other purposes of the external device, the effectiveness of washing machine is improved.
- The objects of the present invention can be achieved by providing a washing machine, comprising: a steam generation unit to generate steam; and an steam outside-supplying pipe connected with the steam generation unit to supply the steam to an outside of the washing machine.
- The steam generation unit can supply the steam into a drum in which washing or drying operation is performed, or to the outside of the washing machine through the steam outside-supplying pipe. Preferably, the washing machine has a button to select steam supply to the outside, and controls to allow the steam to be supplied to the outside through the steam outside-supplying pipe instead of the drum when the steam supply to the outside is selected.
- Preferably, the steam outside-supplying pipe is able to be drawn out from the washing machine. The steam outside-supplying pipe has a sufficient length, and is received in the washing machine so that the steam outside-supplying pipe can be easily drawn out from the washing machine by simply pulling out the steam outside-supplying pipe from the washing machine.
- Preferably, the steam outside-supplying pipe has an adjustable length so that the steam outside-supplying pipe is extended, and drawn to the outside when drawing the steam outside-supplying pipe to the outside. To this end, at least a portion of the steam outside-supplying pipe may be formed of a corrugated pipe, which has an adjustable length like a bellows pipe. Alternatively, the steam outside-supplying pipe may have a telescopic shape so as to be adjustable in length.
- In addition, in order to supply the steam to the outside, a mounting part is formed on a cabinet which defines an appearance of the washing machine, and has one end connected with the steam outside-supplying pipe and the other end with which a separate outer connection pipe is detachably connected from the outside.
- In accordance with another aspect of the present invention, there is provided a washing machine, comprising: a steam generation unit to generate steam; a laundry-receiving device having a space to receive laundry when unfolded; and a laundry-steam supplying pipe connected with the steam generation unit to supply the steam to the laundry-receiving device.
- As such, the washing machine comprises the laundry-receiving device, and is adapted to supply the steam from the steam generation unit to the laundry-receiving device.
- The laundry-receiving device has a foldable structure, and is thus received in a folded state inside or outside the washing machine when it is not used.
- The laundry-receiving device may comprise a base; a cover to cover the base; and a body between the base and the cover to provide the space for receiving the laundry when unfolded.
- When the laundry-receiving device is not used, the body is received in the folded state within the base, covered by the cover, and received in this state.
- Preferably, the laundry-receiving device comprises an opening and closing structure in order to allow easy input and withdrawal of the laundry. For example, the laundry-receiving device may have a zipper structure formed on the body.
- Preferably, the body is formed of a flexible material, and comprises a supporting structure in order to allow the body to be maintained in the folded state. The supporting structure may be a link structure or a telescopic structure. The supporting structure may be connected between the base and the cover such that the cover is separated from the base and supported thereby to allow the body to be maintained in the folded state.
- In addition, preferably, the laundry-receiving device is adapted to receive the laundry in a hung state therein. When the laundry is laid on a shelf-shaped member, effect of removing the wrinkles with the steam can be lowered. Thus, it is desirable to have the laundry-receiving device such that the laundry is received in the laundry-receiving device while being hung on a hanger thereof.
- Although the laundry-steam supplying pipe can be secured to the cover or the base, it is desirable that the laundry-steam supplying pipe be detachably connected therewith.
- Preferably, the washing machine has an accommodation space defined therein to accommodate and receive the laundry-receiving device described above. For example, the washing machine may be provided with a structure which is capable of being input thereto or withdrawn therefrom like a drawer to accept and preserve the laundry-receiving device.
- At this time, the base is integrally formed with a support having the drawer structure.
- The laundry-steam supplying pipe has an adjustable length.
- In accordance with yet another aspect of the present invention, there is provided a washing machine, comprising: a steam generation unit to generate steam; a drum to receive laundry to be washed or dried; a laundry-receiving device having a space to receive the laundry when unfolded; a laundry-steam supplying pipe having a steam-laundry valve controlled by a controller to supply the steam to the laundry-receiving device; and a drum-steam supplying pipe having a steam-drum valve controlled by the controller to supply the steam to the drum.
- The controller controls the steam-laundry valve and the steam-drum valve to allow the steam to be supplied to the drum or to the laundry-receiving device.
- The steam-drum valve and the steam-laundry valve are solenoid valves.
- Although the laundry-steam supplying pipe and the drum-steam supplying pipe can be provided separately, it is desirable that a single pipe be branched to the laundry-steam supplying pipe and the drum-steam supplying pipe. In addition, the steam-laundry valve and the steam-drum valve are integrated into a single valve at a branched portion of the single pipe. Preferably, the integral valve is a three-way valve. With this structure, it is possible to selectively supply the steam only to the drum, to the laundry-receiving device, or to both the drum and the laundry-receiving device.
- The pipes may have a check valve installed therein to prevent reverse flow of the steam, if necessary.
- In accordance with yet another aspect of the present invention, a method for controlling the washing machine comprises: a) selecting a course requiring steam; b) determining an object to be supplied with the steam according to the selected course; c) controlling a valve of a steam supplying pipe to supply the steam to the determined object; and d) generating and supplying the steam through control of a steam generation unit.
- In this structure, a user selects a predetermined operation course using a button on a control panel, and determines an object to be supplied with the steam if the selected course is a course requiring the steam, so that steam is generated and supplied to the object.
- For example, if the selected course is a washing course which employs the steam, the controller determines to supply the steam to the drum, and controls the steam generation unit to generate the steam and the valve to allow the steam to be supplied to the drum.
- In the washing machine comprising the laundry-receiving device, the course may be at least one of a course requiring steam supply to the drum, a course requiring the steam supply to the laundry-receiving device, and a course requiring the steam supply to both the drum and the laundry-receiving device.
- In the washing machine capable of supplying the steam to the outside, the course may be at least one of a course requiring steam supply to the drum, a course requiring the steam supply to the outside of the washing machine, and a course requiring the steam supply to both the drum and the outside of the washing machine.
- Preferably, operation of the steam generation unit is controlled on the basis of at least one of operation cycle, operation temperature, and operation time. For example, the steam generation unit can be operated for a preset period of time, or operated with reference to a preset temperature. In addition, preferably, the temperature is an inner temperature of the tub.
- According to the present invention, the steam can be used for various operations in addition to washing or drying operation within the drum. As a result, it is possible to enhance effectiveness of the washing machine while providing various functions.
- According to the present invention, since the washing machine comprises the separate laundry-steam supplying pipe, and removes wrinkles on the laundry by supplying the steam to the laundry received therein, the washing machine can provide a water washing effect without using water. Furthermore, the effect of water washing can be further enhanced by using a deodorant or aromatic agent. In addition, when preserving out-of-season laundry for a long period of time in the washing machine of the present invention, it is possible to store the laundry with a good condition while preventing the laundry from being dirtied. The washing machine of the present invention provides convenience to the user in that, if the user controls the washing machine to supply the steam to the laundry-receiving device after taking off and hanging clothes in the laundry-receiving device in the evening, he or she can wear the clothes, which look like newly washed clothes, the next morning.
- Since it is possible to supply the steam from the steam generation unit installed in the washing machine to the outside through the steam outside-supplying pipe, the washing machine can be applied to various uses. For example, the washing machine can supply the steam to a refresh part at the outside, and provide swelling and sterilizing effects for the laundry such as underwear, which is desired to be washed with water, by supplying the steam to the laundry. In addition, when the user employs a steam iron, it is possible to use the steam of the washing machine. As such, the steam generation unit of the washing machine can be applied to various uses in addition to the above examples.

FIG. 17 is a flow diagram illustrating a method for controlling the washing machine of the present invention. - Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in
FIGS. 1 to 15 . - Referring to
FIG. 1 , a drum type washing machine will be described as one example of a washing machine according to a preferred embodiment of the present invention. The washing machine of the present invention generally comprises abody 110, atub 120, adrum 130, a steam generation unit, and an steam outside-supplyingpipe 180. - The
body 110 defines an appearance of the washing machine, and is formed at a front side thereof with aninput port 111 - The
body 110 has adoor 140 mounted on theinput port 111 to open and close theinput port 111, and arim 112 mounted around an inner periphery of theinput port 111 to seal between the door and theinput port 111. - The
body 110 is provided with awater supplying pipe 113 to supply water into thetub 120. - The
tub 120 is provided in thebody 110 in a state of being supported therein. - The
drum 130 is rotatably installed in thetub 120 such that thedrum 130 has an opening facing theinput port 111 of thebody 110. - The steam generation unit serves to generate supply steam. According to the present invention, the washing machine comprises at least one steam generation unit.
- After being generated by the steam generation unit, steam is supplied into the
drum 130 through apipe 160. - The steam generation unit is installed in the washing machine to generate and supply the steam into the
drum 130 by heating water with hot air having a high temperature. - The
pipe 160 used for supplying the steam into the drum comprises aninjection nozzle 170. - The
pipe 160 further comprises afirst valve 161 provided at a passage of the pipe to selectively open and close the passage. Theinjection nozzle 170 is adapted to allow efficient injection of the steam, and is installed to the washing machine while penetrating therim 112 such that the tip of theinjection nozzle 170 faces an inner space of thedrum 130. - The steam outside-supplying
pipe 180 enables the steam generated by the steam generation unit to be supplied to a separate external device outside the washing machine instead of being supplied into thedrum 130. - The steam outside-supplying
pipe 180 has one end connected with the steam generation unit, and the other end which can be selectively drawn out from thebody 110. - The other end of the steam outside-supplying
pipe 180 is adapted to be drawn out through at least one of a front surface, a peripheral surface, an upper surface, a rear surface and a bottom surface of thebody 110. - According to a first embodiment of the present invention, the other end of the steam outside-supplying
pipe 180 is drawn out through a lower end of the front side of thebody 110. - Of course, when the washing machine further comprises a
support 190 which covers a predetermined accommodation space defined below the bottom surface of the washing machine as shown inFIG. 2 , the other end of the steam outside-supplyingpipe 180 may be adapted to be drawn out to the outside after sequentially passing through the bottom surface of thebody 110 and thesupport 190. - In addition, the steam outside-supplying
pipe 180 is preferably provided with asecond valve 181 to selectively open and close the passage thereof. - At this time, the
second valve 181 is operated to close the passage of the steam outside-supplyingpipe 180 if it is not necessary to supply the steam through the steam outside-supplyingpipe 180. - Meanwhile, it is more preferable that the steam outside-supplying
pipe 180 has an adjustable length. - This structure is for the purpose of enabling the washing machine and a device requiring the steam supply to be connected with each other even if they are separated a predetermined distance from each other.
- To this end, according to the first embodiment of the present invention, a steam discharge port of the steam outside-supplying
pipe 180 is formed of a stretchablecorrugated pipe 182 in order to have the adjustable length, as shown inFIG. 1 . - Of course, a
steam discharge port 182 of the steam outside-supplyingpipe 180 may be formed of a telescopic pipe which consists of multiple parts overlapped with each other in order to have the adjustable length. - If the
body 110 is provided with thesupport 190 having a predetermined accommodation space below the bottom surface thereof, and thesteam discharge port 182 of the steam outside-supplyingpipe 180 is exposed to the outside after passing through thesupport 190, although not shown in the drawings, thesteam discharge port 182 of the steam outside-supplyingpipe 180 may be formed of a hose having a sufficient length such that the steam outside-supplyingpipe 180 can be accommodated in thesupport 190. - That is, with this configuration, when the
steam discharge port 182 of the steam outside-supplyingpipe 180 is drawn out to the outside, a portion of thesteam discharge port 182 accommodated in thesupport 190 is drawn out instead of changing the length of thesteam discharge port 182. - A steam supplying process using the washing machine according to the first embodiment of the present invention will be described with reference to
FIGS. 1 to 3 . - First, when a user wants to supply steam to a separate external device denoted by
reference numeral 500, thesteam discharge port 182 of the steam outside-supplyingpipe 180 having a portion thereof exposed to the outside from a front lower end of thebody 110 in an initial state as shown inFIG. 1 is drawn out to the outside, and connected with theexternal device 500. - At this time, the
steam discharge port 182 of the steam outside-supplyingpipe 180 formed of the corrugated pipe is gradually stretched from a folded state by a distance to be drawn out to the outside, and is then connected with theexternal device 500. This state is shown inFIG. 3 . - In this state, when the washing machine is controlled to allow the steam to be supplied into the steam outside-supplying
pipe 180, heat generated from theheater 150 constituting the steam generation unit evaporates water in the steam generation unit, and generates the steam. Then, the steam flows through thepipe 160 or the steam outside-supplyingpipe 180. - At this time, the
first valve 161 of the passage of thepipe 160 is operated to maintain a closed state of the passage, while thesecond valve 181 of the passage of the steam outside-supplyingpipe 180 is operated to maintain an open state of the passage. - Thus, the steam generated by the steam generation unit flows only through the steam outside-supplying
pipe 180, and is then supplied to theexternal device 500 so as to be used in theexternal device 500 according to its purpose. - For example, if the
external device 500 is an apparatus for refreshing the laundry, the steam is used for the purpose of the apparatus. On the other hand, if theexternal device 500 is a dish washer or a dish dryer, the steam is used for sterilization of dishes, and if theexternal device 500 is a cleaner, the steam is used for sterilization or cleaning. - Meanwhile, it should be noted that the configuration of the steam outside-supplying
pipe 180 according to the present invention is not limited to the configuration of the first embodiment wherein the steam outside-supplyingpipe 180 is drawn out itself, and connected with theexternal device 500. - In other words, if the
external device 500 has a separate outer connection pipe to receive the steam, the steam outside-supplyingpipe 180 may have configuration which enables the separate outer connection pipe to be connected thereto. - In this regard, a second embodiment of the present invention provides a washing machine which is adapted to permit mounting of the outer connection pipe, which will be described in detail with reference to
FIG. 4 . - First, the washing machine according to the second embodiment generally comprises a
body 210 having a mountingpart 214, adrum 230, a steam generation unit, and an steam outside-supplyingpipe 280. - The mounting
part 214 is formed of a pipe configured so as to allow the outer connection pipe to be connected thereto from the outside. - The mounting
part 214 is formed on at least one of a front surface, a peripheral surface, an upper surface, a rear surface and a bottom surface of thebody 210. Thebody 210 may have one or more mountingparts 214. - According to the second embodiment, the mounting
part 214 is formed at a lower side of the front surface of thebody 210. - Of course, if the
