Description
- This application claims the benefit of Korean Patent Application No. 10-2007-0096565, filed on Sep. 21, 2007, which is hereby incorporated by reference in its entirety.
- 1. Field of the Invention
- The present invention relates to a laundry machine to wash or dry laundry. The laundry machine includes a washing machine, a dryer, a drying and washing machine or the like. Recently, the laundry machine includes a steam generator. The present invention relates more particularly to a laundry machine having a steam generator.
- 2. Discussion of the Related Art
- Generally, washing machines include a pulsator type washing machine and a drum washing machine. Further, the washing machines also include a drying and washing machine which can perform both washing and drying.
- A dryer is an electric home appliance which generally dries washed laundry, mainly, clothes using high-temperature air. The dryer generally includes a drum which accommodates the laundry therein, a driving device which drives the drum, a heating unit which heats air introduced into the drum, a blower unit to make the heated air to flow into the drum, and the like.
- The dryers are classified into an electric dryer and a gas-type dryer according to an air heating method, i.e., a heating unit. The electric dryer heats air using electric resistance heat, and the gas-type dryer heats air using heat generated by gas combustion. In another way, the dryers can be classified into a condensation dryer and an exhaust dryer. In the condensation dryer, humid air which has been heat-exchanged with the laundry in the drum is circulated without being discharged to the outside, and the humid air is converted into condensed water in a separate condenser by heat exchange with outside air to be discharged to the outside. In the exhaust dryer, humid air which has been heat-exchanged with the laundry in the drum is directly discharged out of the dryer.
- A conventional laundry machine may include a steam generator. A washing machine using steam in the washing operation has a good washing performance.
- When water is supplied into the steam generator over a required level, water may overflow through a steam line. Particularly, when water is supplied into the steam generator through a faucet and a water supply valve, if the water supply valve is out of order, water can continuously flow into the steam generator, thereby causing overflow. In case of a dryer, overflowing water may be introduced into the drum and wet the laundry. Further, since the dryer generally does not have a drain line for discharging water out of a drum or a tub, differently from the washing machine, the problem becomes worse.
- Also in the washing machine, water can overflow the steam generator due to an error in the water supply to flow into the tub, thereby causing a problem.
- The present invention is related to a laundry machine that substantially obviates one or more problems due to limitations and disadvantages of the related art.
- Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or can be learned from practice of the invention. The objectives and other advantages of the invention can be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
- An embodiment of the present invention comprises a drum in which laundry is put; a steam generator to generate steam; a water supply line connected to the steam generator; a steam line connected to the steam generator; and a valve placed in the steam line, wherein the valve is controlled to block overflowing water from the steam generator.
- In the above embodiment, water can be prevented from flowing to the drum through the steam line.
- The water supply line can be connected to a faucet and a water supply valve. In this case, even though water is over supplied to the steam generator due to a malfunction of the water supply valve or the like, the water does not flow into the drum by the valve installed on the steam line. However, when water is intended to be supplied to the drum through the steam line after passing through the steam generator, the valve installed on the steam line can be controlled according to the conditions.
- The valve installed on the steam line can be controlled according to a temperature of the steam generator. In this case, the temperature of the steam generator can be one of a temperature of a body of the steam generator, a temperature of atmosphere in the steam generator, and a temperature of water in the steam generator.
- When the temperature of the steam generator is equal to or larger than a preset temperature, the valve installed on the steam line can be controlled to be kept open. For example, the valve installed on the steam line which maintains a closed state can be controlled to be opened when the temperature of the steam generator reaches 100° C. When water is over supplied to the steam generator and overflows the steam generator, the temperature of the steam generator would be lower than the preset temperature. In this case, since the valve installed on the steam line is in a closed state, overflowing water does not flow into the drum through the steam line.
- Meanwhile, the valve installed on the steam line can be controlled to be opened after a predetermined period of time after the heater of the steam generator is turned on, instead of being controlled according to a temperature as described above.
- In this case, the valve installed on the steam line can be controlled to be closed at the same time when the water supply valve is closed as water supply into the steam generator is completed. Even though the water supply valve is not closed due to a malfunction, water is not introduced into the drum by being blocked by the valve installed on the steam line.
- Further, the valve installed on the steam line can be controlled according to an amount of water to be supplied into the steam generator. For example, if the amount of water supplied into the steam generator is equal to or larger than a preset amount, the valve is controlled to be closed. In this case, the preset amount can be set to be equal to or larger than an allowable water supply amount of the steam generator. Further, the preset amount can be set to be larger than a set amount by which water is supplied into the steam generator.
- The laundry machine can further include an instrument to measure an amount of water supplied into the steam generator. The instrument can be any device capable of detecting an amount of water supplied into the steam generator.
- For example, the instrument can include an impeller installed on the water supply line and a detection unit to detect the number of rotation of the impeller. Accordingly, if the impeller rotates by a preset number or more, the valve installed on the steam line is closed.
- Further, the instrument can include a water level sensor which senses a water level in the steam generator. The water level sensor senses a maximum allowable water level of the steam generator. If the maximum allowable water level is sensed by the water level sensor, the valve installed on the steam line can be controlled to be closed. In this case, the maximum allowable water level can be determined as a water level over which water is supplied to cause overflow through the steam line.
- The water level sensor can be configured to sense another preset level in the steam generator. For example, the water level sensor can be configured to sense a first water level, a second water level and the maximum allowable water level. If a water level reaches the second water level, the water supply valve is controlled to be closed. The first water level is provided to prevent the heater installed in the steam generator from being exposed above the surface of the water. For example, if a water level in the steam generator gradually decreases and then reaches the first water level, the heater can be controlled to be turned off in order to prevent from being overheated.
- Further, the valve installed on the steam line can be controlled according to time. For example, the valve can be controlled to be closed within a preset period of time after the water supply valve is closed as water supply into the steam generator is completed and, then, opened after a preset period of time.
- According to the present invention, even though water is over-supplied to the steam generator, the water can be prevented from flowing into the drum. Particularly, even when there is an error in the water supply, the water can be prevented from overflowing the steam generator and flowing into the drum.
- It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
- The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principle of the invention.

- Hereinafter, a laundry machine according to an embodiment of the present invention will be described with reference to
FIGS. 1 to 3 . For convenience, a top-loading, electric, condensation dryer is explained as an example, but the present invention is not limited thereto. - A
rotatable drum 20, amotor 70 which drives thedrum 20 and abelt 68 are installed inside acabinet 10 forming an external appearance of the dryer. Further, a heater 90 (hereinafter, simply referred to as a “hot air heater”) which heats air to produce high-temperature air (hereinafter, referred to as “hot air”) and a hot air supply duct 44 which supplies hot air produced in thehot air heater 90 to thedrum 20 are installed at specific positions of thecabinet 10. Further, anexhaust duct 80 which discharges humid air that has been heat-exchanged with laundry in thedrum 20, and ablower unit 60 which sucks the humid air are installed in thecabinet 10. Meanwhile, asteam generator 200 is installed at a specific position of thecabinet 10 to generate high-temperature steam. Although an indirect drive type dryer which rotates thedrum 20 using themotor 70 and thebelt 68 is shown and described in this embodiment, the present invention is not limited thereto. That is, a direct drive type dryer which directly rotates thedrum 20 by a motor directly connected to the rear surface of thedrum 20 can be applied to the present invention. - The respective components are described in detail below.
- The
cabinet 10 forming an external appearance of the dryer includes a base 12 forming a bottom surface, a pair of side covers 14 vertically installed on thebase 12, afront cover 16 and arear cover 18 respectively installed on the front and rear surfaces of the side covers. 14, and atop cover 17 positioned at an upper portion of the side covers 14. Acontrol panel 19 having various control switches and the like is generally disposed on thetop cover 17 or thefront cover 16. Adoor 164 is installed on thefront cover 16. Therear cover 18 includes asuction port 182 which introduces outside air and anexhaust hole 184 serving a final passage to discharge air in thedrum 20 to the outside. - An inner space of the
drum 20 serves as a drying chamber to perform a drying operation, and thedrum 20 has alift 22 therein. - Meanwhile, a
front supporter 30 and arear supporter 40 are installed between thedrum 20 and the cabinet 10 (thefront cover 16 and the rear cover 18). Thedrum 20 is rotatably installed between thefront supporter 30 and therear supporter 40. Sealing members (not shown) are installed between thefront supporter 30 and thedrum 20 and between therear supporter 40 and thedrum 20, respectively, to prevent leakage. That is, thefront supporter 30 and therear supporter 40 close the front and rear surfaces of thedrum 20 to form the drying chamber and serve to support a front end and a rear end of thedrum 20. - An opening is formed on the
front supporter 30 such that thedrum 20 communicates with the outside of the dryer. The opening is selectively opened and closed by thedoor 164. Further, alint duct 50 serving as a passage for discharging air of thedrum 20 to the outside is connected to thefront supporter 30, and alint filter 52 is installed in thelint duct 50. Thelint duct 50 is connected to one side of theblower unit 60, and the other side of theblower unit 60 is connected to theexhaust duct 80. Theexhaust duct 80 communicates with theexhaust hole 184 disposed on therear cover 18. Accordingly, when theblower unit 60 is operated, air in thedrum 20 is discharged to the outside through thelint duct 50, theexhaust duct 80 and theexhaust hole 184. In this case, foreign matter such as nap is filtered by thelint filter 52. Generally, theblower unit 60 includes ablower 62 and ablower housing 64, and theblower 62 is connected to and driven by themotor 70 for driving thedrum 20. Anopening 42 generally having a number of through holes is formed on therear supporter 40. Theopening 42 is connected to the hot air supply duct 44. The hot air supply duct 44 communicates with thedrum 20 to serve as a passage for supplying hot air to thedrum 20. Accordingly, thehot air heater 90 is installed at a specific position of the hot air supply duct 44. - Meanwhile, the
steam generator 200 is installed at a specific position of thecabinet 10 to generate steam and supply the steam into thedrum 20. Thesteam generator 200 is described in detail below with reference toFIG. 3 . - The
steam generator 200 includes awater tank 210 for accommodating water therein, aheater 240 mounted in thewater tank 210, awater level sensor 260 which measures a water level of thesteam generator 200, and atemperature sensor 270 which measures a temperature of thesteam generator 200. Thewater level sensor 260 includes acommon electrode 262, a lowwater level electrode 264 and a highwater level electrode 266. Thewater level sensor 260 detects a high water level and a low water level according to whether thecommon electrode 262 is electrically connected to the highwater level electrode 266 or whether the common electrode is electrically connected to the lowwater level electrode 264. - A
water supply hose 220 for supplying water is connected to one side of thesteam generator 200 and asteam hose 230 for discharging steam is connected to the other side of thesteam generator 200. It is preferable to provide anozzle 250 at a leading end of thesteam hose 230. A faucet and awater supply valve 281 are connected to one end of thewater supply hose 220. A leading end portion of thesteam hose 230 or thenozzle 250, that is, a steam discharge port, is disposed at a specific position of thedrum 20 to spray steam into thedrum 20. Although thenozzle 250 is disposed at the front of thedrum 20 in this embodiment, thenozzle 250 can be installed on therear supporter 40. - Further, a
valve 282 is installed on thesteam hose 230. A controller opens thewater supply valve 282 to supply water to thesteam generator 200. When it is determined that the water level in thesteam generator 200 reaches a high water level based on a signal of thewater level sensor 260, the controller closes thewater supply valve 282. In this case, thevalve 282 installed on the steam hose is also closed. - Then, the controller turns on the
heater 240 to heat water in thesteam generator 200. As time goes by, when an inner temperature of thesteam generator 200 increases and reaches a preset temperature, thevalve 282 installed on thesteam hose 230 is opened. The steam generated in thesteam generator 200 is supplied to thedrum 20 through thesteam hose 230. - Meanwhile, a flowmeter can be installed on the water supply hose to detect an amount of water supplied into the steam generator. Generally, the flowmeter is a conventional well-known impeller flowmeter. The amount of water supplied through the water supply hose is detected using the rotation number of the impeller. The controller receives a signal of the flowmeter and closes the water supply valve when the amount of water reaches a preset amount.
- Further, the water level sensor can be used. For example, if a high water level is sensed by a high water level terminal of the water level sensor, the valve installed on the steam hose is closed. In another way, a terminal capable of sensing a water level higher than the water level sensed by the high water level terminal (so-called ‘critical water level terminal’) can be further provided and used. If a critical water level is sensed by the critical water level terminal, the valve of the steam hose is closed. In this case, the critical water level can be set as a maximum allowable water level of the steam generator.
- The present invention relates to a laundry machine to wash or dry the laundry. According to the present invention, even though water is excessively supplied to the steam generator and overflow is generated, it is possible to prevent the water from flowing into the drum. Particularly, even when there is an error in the water supply, it is possible to prevent water from overflowing the steam generator and flowing into the drum.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
