Description

CROSS-REFERENCE TO A RELEVANT APPLICATION

This application claims the benefit of the filed January 12, 2007 Korean Patent Application No. 10-2007-0003716 ( KR 10 2007 118 527 A ), which is hereby incorporated by reference in its entirety as if fully set forth herein.

BACKGROUND OF THE INVENTION

Field of the invention

The present invention relates to a clothes treating machine and a control method thereof, and more particularly relates to a clothes treating machine and a control method thereof which can remove wrinkles or creases on clothes.

Discussion of the relevant art

A clothes treating machine is a household electric appliance that dries washed clothes, such as washed clothes, using high-temperature air. In general, a clothes treating machine has a drum for receiving an object to be dried, a drive source for driving the drum, a heating unit for heating air to be introduced into the drum, and a blower unit for drawing air into the drum and blowing out air, respectively you.

Based on how air is heated, d. H. On the basis of the type of heating unit, clothes treating machines may be classified as electric clothes treating machines or gas operated clothes treating machines. An electric clothes treating machine heats air using electric resistance heat, whereas a gas-powered clothes treating machine heats air using heat generated by the combustion of gas. In addition, clothes treating machines may be classified as condensation type or exhaust type ones. In a condensation type clothes treating machine, air which has undergone heat exchange with an object to be dried in a drum and transferred to a high-humidity phase is circulated without discharging the air from the clothes treating machine. Heat exchange occurs between an auxiliary condenser and the outside air to produce condensed water, which is discharged from the clothes treating machine. In an exhaust-type garment treating machine, air which has undergone heat exchange with an object to be dried in a drum and has been changed to a high-humidity phase is directly blown out of the garment treating machine. Based on how laundry is fed into the clothes treating machine, clothes treating machines may be classified into top loading type or front loader type ones. In a top loading type clothes treating machine, an object to be dried is input to the clothes treating machine from above. In a front loading type garment treating machine, an object to be dried is fed from the front into the garment treating machine.

However, a conventional clothes treating machine having the above construction has the following problems.

In general, clothing which has already been washed and dried by spin is put in a clothes treating machine to be dried by it. However, the water-washed garment has wrinkles due to the principle of washing with water, and these wrinkles on the garment are not completely removed during the drying process performed by the garment treating machine. Accordingly, an additional ironing process is required to remove wrinkles from a dried object, i. H. Clothing, which has already been dried by the conventional clothing treatment machine.

Further, when clothes and laundered clothing are normally stored and used, they may have the same wrinkles, creases or wrinkles (hereinafter generally referred to as "wrinkled"). Accordingly, there is a strong demand for a device that can easily and conveniently remove wrinkles thereon during normal use and storage of clothes.

The older, not pre-published DE 10 2007 007 354 A1 shows a clothes dryer with an optional rotatable drum which receives an object to be dried, a steam supply device whose one side is connected to a steam generator and the other side to the drum, and a swirler, which is installed in the steam supply device to one through the Steam supply device to swirl flowing steam. One method of controlling the tumble dryer involves heating the drum, feeding steam into the drum that has been generated in a steam generator, and supplying hot air to the drum. With such a dryer, creases in garments can be eliminated.

EP 1 666 655 A2 shows an apparatus and method for eliminating wrinkles in garments in a washing machine or laundry drying machine using steam. Here, wrinkles in clothing that has been worn or stored by a user can be eliminated. Also, generation of wrinkles can be prevented after the washing of the clothes is completed. The method includes determining if a wrinkle removal run is selected; supplying hot air to the clothes to remove dust from the clothes when it is determined that the wrinkle removal run is selected; and supplying steam to the clothing from which the dust has been removed to remove the wrinkles in the clothing.

Summary of the invention

Accordingly, the invention is directed to a control method for a clothes treating machine which can prevent and / or eliminate wrinkles or creases on clothes.

In the case 10 are also an exhaust air tract 80 for venting high-humidity air with an object to be dried in the drum 20 carried out a heat exchange, from the dryer and a blower unit 60 attached to the intake of high-humidity air. There is also a steam generator 200 for generating high temperature steam at a predetermined position in the housing 10 appropriate. In this embodiment, for convenience of description, an indirect drive system is shown and described in which the drum 20 using the motor 70 and the belt 68 is turned. However, the invention is not limited to an indirect drive system. For example, the invention may be applied to a direct drive system in which the motor is directly connected to the back of the drum 20 is connected so that it is rotated by this directly.

Now, the respective components of the clothes treating machine will be described in detail.

The housing 10 determines the outer appearance of the clothing treatment machine. The housing 10 has a base forming its base 12 , a pair of vertically attached side covers 14 , a front cover 16 and a back cover 18 at the front or back of the side covers 14 attached, and a top cover 17 , which are at the top of the side covers 14 located. Usually is on the top cover 17 or the front cover 16 a control panel 19 arranged with various control switches. At the front cover 16 is a door 164 appropriate. The back cover 18 is with a suction unit 182 , is introduced through the outside air, and an outlet hole 184 provided with a closing channel for discharging air in the drum 20 out of the case 10 forms.

The interior of the drum 20 serves as a drying chamber in which a drying process is carried out. Inside the drum 20 are preferably lifting wings 22 attached to raise the object to be dried and drop, so that it is turned over to increase the drying efficiency.

On the other hand, there are between the drum 20 and the housing 10 ie between the drum 20 and the front cover 16 as well as between the drum 20 and the rear cover 18 a front camp 30 or a rear bearing 40 appropriate. The drum 20 is between the front bearing 30 and the rear bearing 40 rotatably mounted. Between the front bearing 30 and the drum 20 as well as between the rear bearing 40 and the drum 20 Sealing members (not shown) for respectively preventing leakage of air are attached. Specifically, close the front bearing 30 and the rear bearing 40 the front and the back of the drum 20 to form the drying chamber. Also serve the front bearing 30 and the rear bearing 40 for supporting the front end or the rear end of the drum 20 ,

In the front camp 30 an opening is formed through which the two communicates with the outside of the clothes treating machine. The opening is through the door 164 selectively opened and closed. Also is with the front bearing 30 a river tract 50 connected, which is a channel for discharging air in the drum 20 from the apparel treatment machine. In the river tract 50 is a lint filter 52 appropriate. One side of the blower unit 60 is with the lintel tract 50 connected while the other side of the same with the exhaust air tract 80 connected is. The exhaust air tract 80 stands with the one in the back cover 18 trained outlet hole 184 in connection. Accordingly, when the blower unit 60 is operated, air in the drum 20 through the river tract 50 , the exhaust air tract 80 and the outlet hole 184 blown out of the clothing treatment machine. This foreign substances, such as lint, through the lint filter 52 filtered out. In general, the blower unit has 60 over a fan 62 and a blower housing 64 , The fan 62 is generally with the the drum 20 driving engine 70 connected.

In the rear warehouse 40 is an opening 42 formed with multiple through holes. The hot air supply tract 44 is with this opening 42 connected. The one with the drum 20 in connection standing hot air supply tract 44 serves as a channel for supplying hot air into the drum 20 , Accordingly, the hot air heater 90 at a predetermined position on the hot air supply tract 44 appropriate.

On the other hand, the steam generator 200 for producing into the drum 20 steam to be supplied at a predetermined position in the housing 10 appropriate. Details of the steam generator 200 be below with reference to the 3 explained.

The steam generator 200 has a water tank 210 for storing water, a heater installed in it 240 , a water level sensor 260 for detecting the water level in the steam generator 200 , and a temperature sensor 270 for detecting the temperature in the steam generator 200 , The water level sensor 260 essentially has a common electrode 262 , a low water level electrode 264 and a high water level electrode 266 , The water level sensor 260 detects a high or low water level in the steam generator 200 based on the power line between the common electrode 262 and the lower water level electrode 264 or the power line between the common electrode 262 and the high water level electrode 266 , With one side of the steam generator 200 is a water supply hose 220 connected to the supply of water. With the other side of the steam generator 200 is a steam hose 230 connected to the discharge of steam. At the front end of the steam hose 230 is preferably a nozzle 250 attached, which is formed with a predetermined shape. In general, one end of the water supply hose 220 connected to an external water supply source, such as a faucet. The front end of the steam hose 230 or the nozzle 250 that is, the steam outlet opening is at a predetermined position in the drum 20 to spray steam into them.

In this embodiment, the steam generator 200 on the other hand constructed according to a construction in which a predetermined, in the water tank 210 with a predetermined amount of stored water through the heater 240 is heated to generate steam (hereinafter referred to as "pan-type steam generator" for convenience of description). However, the invention is not limited to the above-mentioned steam generator. Accordingly, the invention may use any steam generator as long as it can generate steam. For example, the steam generator 200 having a structure in which the heater is attached directly to the water supply hose through which water passes, to heat water without storing it in a predetermined space (hereinafter referred to as a "heater-type steam generator" for the sake of brevity). ,

Now, referring to the 4 another embodiment of a clothing treatment machine according to the invention described.

In this embodiment, a water supply source 300 for supplying water to the steam generator 200 detachably attached to the clothing treatment machine. As in the previous embodiment, the water supply source may be a faucet. In this case, however, the installation of the water supply source is very complicated. Since water is generally not used in a dryer, and when a faucet is used as a water supply source, it is necessary to install various devices connected to the faucet. In this embodiment, therefore, the removable Wasserzuführquelle 300 used. More specifically, the water supply source becomes 300 from the steam generator 200 separated to fill with wet water. After the water supply source 300 was filled with water, it is with the water supply channel of the steam generator 200 ie the water supply hose 220 , connected, which is very clever.

Between the water supply source 300 and the steam generator 200 is preferably a pump 400 appropriate. The pump preferably rotates in the clockwise and counterclockwise directions. Accordingly, it is possible to supply water to the steam generator 200 to deliver, and, if necessary, it is possible to remove any remaining water from the steam generator 200 to collect. However, it is also possible to use Nasser using the water supernatant difference between the water supply source 300 and the steam generator 200 feed without the pump 400 would be used. However, various components of the clothes treating machine are usually standard items designed with a compact construction, with the result that the design space available in the clothes treating machine is completely insufficient. For this reason, a water supply using a water supernatant difference is actually impossible unless the size of various components of a conventional clothes treating machine is changed. Accordingly, it is when the small pump 400 used, possible, the steam generator 200 without having to resize various components of a conventional clothes treating machine, therefore, the use of the pump 400 is very cheap. Also, there is a reason for collecting remaining water from the steam generator 200 in that the heater through in the steam generator 200 Any remaining wet water can be damaged, or decomposed water can subsequently be used if the steam generator 200 was not used for a long time.

In the previous embodiment, water is in the upper part of the steam generator 200 supplied and steam is discharged from the upper part thereof. On the other hand, in this embodiment, water is in the lower part of the steam generator 200 supplied and steam is discharged from the upper part thereof. This construction is for collecting the remaining water from the steam generator 200 advantageous.

Also, it is preferably on a steam channel for discharging steam from the steam generator 200 ie a steam hose 230 , a safety valve 500 appropriate.

Hereinafter, the respective components of the clothes treating machine will be described in detail.

First, referring to the 5 the details of the removable water supply source 300 (hereinafter referred to as "cartridge" for convenience of description).

The bullet 300 has a lower housing 310 for receiving water and a detachably attached to this upper housing 320 , If the cartridge 300 with a construction with the lower housing 310 and the upper case 320 is constructed, it is easy to clean deposits that are in the cartridge 300 accumulate. Besides, it's easy to filter 330 and 340 and a water softening element 350 from the upper and the lower housing separate and the separate filters 330 and 340 and the separate water softening element 350 to clean or regenerate.

At the upper case 320 is preferably a first filter 330 appropriate. More precisely, it is the first filter 330 in a water inlet part of the upper housing 320 attached to carry out a primary filtration of water, if such to the cartridge 300 is delivered.

At the bottom of the house 310 is preferably an opening / closing element 360 for selective discharge of water in the cartridge 300 attached to the outside. Accordingly, if the cartridge 300 is disconnected from the clothing treatment machine, the water in it is not discharged to the outside, and then when the cartridge 300 in the clothes treating machine, water in it can be discharged to the outside. At the opening / closing element 360 is preferably a second filter 340 attached to filter water. It is more preferable if the second filter 340 removable on the opening / closing element 360 is appropriate. By attaching the first filter 330 and the second filter 340 it is possible to filter out foreign substances, such as microdust, twice from the water. Preferably, the first filter exists 330 from a network of about 50 mesh, and the second filter 340 consists of a grid with about 60 mesh. Here, a mesh of 50 mesh is one constructed by a construction according to the number of meshes per unit area 50 is. Accordingly, the size of the meshes of the first filter 330 forming pores larger than that of the meshes of the second filter 340 forming pores. As a result, large impurity particles are primarily through the first filter 330 filtered out while small impurity particles secondary filtering through the second filter 340 Experienced.

In the cartridge 300 is preferably a water softening element 350 attached to soften water. More preferred is the water softening element 350 removable in the cartridge 300 appropriate. As it is in the 6 has the water softening element 350 via a lower housing 352 with multiple through holes and an upper housing 353 Removable at the lower case 352 is appropriate. The upper case 353 has several through holes. Preferably, one is between the upper housing 353 and the lower case 352 formed space filled with an ion exchange resin (not shown).

The reason, the water softening element 350 to use is the following. When the hardness of the steam generator 200 When the water to be supplied is high, lime such as calcium carbonate (CaCO ₃ ) may be precipitated when calcium hydrogencarbonate (Ca (HCO ₃ ) ₂ ) dissolved in water is heated, and the heater may be corroded by the lime. In particular, water in Europe and America is hard water with high hardness. For this reason, the above effect can be serious. Accordingly, it is preferable to preliminarily remove calcium and magnesium ions using an ion exchange resin to thereby prevent the precipitation of lime. The efficiency of the ion exchange resin decreases when the water softening process is carried out. Accordingly, it is possible to regenerate the ion exchange resin using a saline solution (NaCl) so that it can be reused. For example, the water softening process using an ion exchange resin is represented by 2 (R-SONa) + Ca 2+ - (R-SO) Ca + 2Na, and the Regeneration process thereof is represented by (R-SO) Ca + 2NaCl <-> 2 (R-SONa) + CaCl.

Hereinafter, the attaching and detaching structure between the second filter 340 and the opening / closing element 360 with reference to the 7A to 7C described in detail.

The opening / closing element 360 is on the lower case 310 the cartridge 300 appropriate. The opening / closing element 360 has a flow channel 362 in conjunction with the cartridge 300 as well as a pen 365 for selectively opening and closing the flow channel 362 , The flow channel 362 has an inner flow channel 362a and an outer flow channel 362b , On the outside of the inner flow channel 362a is a locking projection 361 educated. The second filter 340 has a coat 341 that with one the inner flow channel 362a corresponding shape is formed, and a filter ring 344 standing on one side of the coat 341 is appropriate. On the other side of the coat 341 is a latching projection 361 of the inner flow channel 362a corresponding groove 362 educated. The groove 362 has a horizontal groove part and a vertical groove part, whereby it is in the form of an "L". Accordingly, as stated in the 7B is shown, the groove 342 More precisely, the horizontal groove part, the second filter 340 an engagement with the locking projection 361 on the inner flow channel 362a It will, as it is in the 7C is shown, the second filter 340 twisted, with the result that there is a coupling between the second filter 340 and the opening / closing element 360 comes. The second filter 340 is in the reverse order of the opening / closing element 360 separated. Accordingly, the separation between the second filter 340 and the opening / closing element 360 not specified.

Below is the connection between the cartridge 300 and the pump 400 with reference to the 8th described in detail.

As it is in the 8th is shown are the cartridge 300 and the pump 400 via an intermediate hose 490 connected with each other. One side of the intermediate hose 490 is directly with an inlet nozzle 430 the pump 400 connected while the other side of the same via a connecting piece 480 with the cartridge 300 connected is. Preferably, the inlet port 430 the pump 400 and the intermediate tube 490 through a bracket 492 firmly coupled together, and the connecting piece 480 and the intermediate tube 490 are also by another parenthesis 492 firmly coupled together, causing leakage from a gap between the inlet port 430 the pump 400 and the intermediate tube 490 and a leak from a gap between the connecting piece 480 and the intermediate tube 490 are prevented.

Below is the connection between the cartridge 300 and the connecting piece 480 with reference to the 9A to 10 described in detail.

As already described, this is with the cartridge 300 related opening / closing element 360 at the cartridge 300 appropriate. The opening / closing element 360 has the flow channel 362 and the pen 365 for selectively opening and closing the flow channel 362 , The flow channel 362 has the inner flow channel 362a and the outer flow channel 362b , Also, on the outside of the outer flow channel 362b an O-ring 369 attached to maintain airtightness.

However, on one side of a pen body 365b of the pen 365 a concave part 366 trained, and on the other side of the pen body 365b of the pen 365 is a flow part 365a trained (see the 10 ). In the concave part 366 is an opening / closing part 367 appropriate. The flow part 365a is formed approximately in a cross shape, so that the water passes between the cross-shaped cutting edges. Preferably, the opening / closing part 367 made of rubber.

In the flow channel 362 is a holding part 363 with several through holes 363a for holding the pen body 365b of the pen 365 appropriate. Between the holding part 363 and the flow part 365a of the pen 365 is a spring 364 appropriate. The connection piece 480 has an outer connection piece 482 with an inner diameter larger than the outer diameter of the outer flow channel 362b of the opening / closing element 360 is, and an inner connecting piece 484 with an outer diameter smaller than the inner diameter of the outer flow channel 362b of the opening / closing element 360 is.

As it is in the 9A is shown, the front end of the inner flow channel 362a through the opening / closing part 367 closed, located on one side of the pen 365 located by the spring 364 elastically biased when the condition exists in which the cartridge 300 from the connecting piece 480 is disconnected. Accordingly, water is in the cartridge 300 not discharged through the flow channel to the outside. If the cartridge 300 in the connecting piece 480 is used as it is in the 9B is shown, the pin is 365 against the elastic force of the spring 364 through the inner connecting piece 484 of the connecting piece 480 from the inner flow channel 362a advanced. Accordingly, the opening / closing part becomes 367 standing on one side of the pen 365 lies, from the front end of the inner flow channel 362a separated, with the result that water flows between them, which is why water in the cartridge through the flow channel to the outside, ie to the pump 400 , is omitted. According to the invention, the leakage of water through the double seal construction using the spring 364 and the O-ring 369 effectively prevented.

As it is in the 10 is shown is one end of the pen 365 ie the interior 366 of the flow part 365a , preferably tapered. In this tapered construction, the cross-sectional area of the flow channel through which water flows increases, as compared to a simple cylindrical structure, whereby a more effective flow of water is achieved.

On the other hand, as it is in the 11 is shown, the cartridge 300 without use of the intermediate tube 490 be directly connected to the pump. In this case it is necessary to change the shape of the inlet nozzle 430a the pump 400 suitable to change so that he has an outer inlet nozzle 432 and an inner inlet nozzle 434 features. More precisely, the inlet port is 430a the pump 400 built so that it over the connecting piece 480 of the 9 having similar construction. This construction shows the advantage that the intermediate hose 490 and the brackets 492 are omitted for sealing, therefore, compared to in the 8th and 9 connecting construction shown, the material costs are reduced and the manufacturing process is simplified.

On the other hand, in the embodiment described above, the first filter 330 , the second filter 340 and the water softening element 350 on the removable cartridge 300 appropriate. However, the invention is not limited to the above construction. For example, the invention can also be applied to a case where an outer faucet serves as a water supply source 300 is used. In this case, it is preferable regarding the first filter 330 , the second filter 340 and the water softening element 350 at least one on with the steam generator 200 attached water supply channel to install. Even in this case, it is preferable to use the first filter 330 , the second filter 340 and the water softening element 350 removable to attach to the water supply channel. It is also preferable that the first filter 330 , the second filter 340 and the water softening element 350 are contained in a single container, which is removably attached to the water supply channel.

Below is the pump 400 with reference to the 12 described.

The pump 400 serves to selectively supply water to the steam generator 200 , More precisely, the pump is spinning 400 in the clockwise and counterclockwise direction, to selectively feed water to the steam generator 200 to deliver or to collect residual water from it.

As a pump 400 a gear pump, a pulsating pump or a diaphragm pump can be used. Even with a pulsating pump or a diaphragm pump, it is possible to change the flow of a fluid by instantaneously changing the polarities of a circuit in the clockwise and counterclockwise directions. The 12 illustrates a gear pump 400 as an example of the pump 400 , The gear pump 400 has a pair of in a housing 410 arranged gears 420 , The housing 410 is with an inlet nozzle 430a and an outlet 414 Mistake. More precisely, the water gets out of the inlet nozzle 430a to the outlet 414 or from the outlet 414 to the inlet nozzle 430a left out, what about the direction of rotation of the gears 420 depends.

Below is the nozzle 250 with reference to the 13 to 17 described in detail.

As it is in the 13 is shown, it is possible to use the nozzle 250 to construct with a common shape. More precisely, it is possible to use the nozzle 250 build up in the form of a relatively large diameter and relatively small diameter pipe, allowing steam through one at the front end 251 the nozzle 250 trained spray hole 251a is sprayed into the drum. Also, the nozzle is 250 preferably with a holding part 259 provided for their installation. If steam in a simple way through the front of the nozzle 250 trained spray hole 251a is sprayed as it is in the 13 is shown, the steam is locally sprayed by its kinetic energy into the drum, whereby the Faltenentferneffizienz can decrease. Accordingly, it is preferable that the shape of the nozzle 250 suitable to change.

The following is with reference to the 14 and 15 another embodiment of the nozzle 250 described.

As shown in the drawings, is at the nozzle 250 an auxiliary nozzle 253 attached to the steam generator 200 connected to spray steam into the drum. In this case, the Duse 250 with a uniform diameter or a relatively large size mold Be constructed diameter and relatively small diameter. If the nozzle 250 is constructed with a relatively large and relatively small diameter mold, it is preferred that the front end 251 the same has a slightly larger diameter. The auxiliary nozzle 253 is constructed with a shape of relatively large and relatively small diameter, preferably conical. Preferably, the outer inclination angle of the auxiliary nozzle 253 smaller than that of the nozzle 250 , For example, the nozzle 250 tilted outward by 30 degrees, whereas the auxiliary nozzle 253 inclined 15 degrees outwards.

With the above construction, it is possible to increase the distribution angle of steam so that clothes can be uniformly wetted by it, thereby improving the wrinkle removing efficiency.

In the 15 indicates the unexplained reference number 259a formed in the holding part connecting holes.

Below is another example of the nozzle 250 with reference to the 16 and 17 described.

Preferably, in the nozzle 250 a whirlpool generating element, for creating a whirlpool, attached. In this case, the nozzle can 250 be designed with a shape of uniform diameter or a shape of relatively large and relatively small diameter. If the nozzle 250 is constructed with a relatively large and relatively small diameter mold, it is preferred that the front end 251 the same has a slightly larger diameter.

Preferably, the whirlpool generating element has blades 257 , Every scoop 257 extends from the inner wall of the nozzle 250 inside. Preferably, each blade is 257 formed with the shape of a curve. The shovels 257 can be in the center of the nozzle 250 be directly connected. Preferably, however, is a central element 258 in the nozzle 250 arranged so that each blade connects between the inner wall of the nozzle 250 and the central element 258 manufactures. More preferred is in the central element 258 a flow channel 258a educated. With this construction, it is possible to improve the moldability and the mass producibility.

In the above construction, during the flow of steam, a whirlpool is generated so as to increase the kinetic energy and the scattering angle, so that clothes can be uniformly wetted by the steam, thereby improving the wrinkle removing efficiency.

However, as it is in the 18 is shown, the nozzle 250 preferably adjacent to the opening 42 , is supplied through the hot air into the drum, arranged so that steam can be sprayed from the front of the drum to the back. This, because air from the rear bearing 40 trained opening 42 is introduced and then to the lintel tract (not shown, see 1 ) under the door 104 is omitted. As a result, the air flow channel serves as a fluffing tract approximately at the opening 42 , Accordingly, when the nozzle flows 250 adjacent to the opening 42 the sprayed steam travels along the air flow channel, wetting the clothes evenly with it.

Meanwhile, the nozzle described in this embodiment can 250 also in a clothes treating machine having a water supply source other than the detachable water supply source 300 be applied. For example, the nozzle 250 be applied in a case where an outer faucet as a water supply source 300 is used.

Below is the safety valve 500 with reference to the 13 and 19 described in detail.

During normal operation of the steam generator 200 steam gets through the steam hose 230 and the nozzle 250 sprayed into the drum. However, if microfibers or fluff or foreign substances, such as those generated during the garment drying process, are present at the spray hole 251a the nozzle 250 If it sticks and accumulates in it, causing it to become clogged, the steam will not be delivered evenly into the drum, but the vapor pressure will act in the reverse direction on the steam generator 200 , As a result, the pressure in the steam generator increases 200 which can destroy it. In particular, the water container generally used in a pan-type heating steam generator is not manufactured according to an internal pressure design for a high pressure container, with the result that the probability of destruction is further increased. Accordingly, it is preferable to attach a suitable safety device.

When the steam flow passage through which the steam generated by the steam generator flows clogs, the safety valve functions 500 so that it lets out the steam to the outside. Accordingly, the safety valve 500 preferably in the steam flow channel, for example the steam hose 230 , appropriate. More preferred is the safety valve 500 near the front end of the steam hose 230 , for example, adjacent to the nozzle 250 , appropriate.

The safety valve 500 has a coat 510 with one end in connection with the steam hose 230 while the other end communicates with the outside, and one in the jacket 510 attached opening / closing part 530 for selectively opening and closing the jacket 510 and the steam hose 230 , More specifically, is the opening / closing part 530 in a vapor flow channel connecting part 513 of the coat 510 appropriate. The opening / closing part is by a spring 520 held. Of course, there is one end of the spring 520 with the opening / closing part 530 connected while the other end of the same with a fixed part 540 connected in a predetermined manner on the jacket 510 is attached. When the steam hose 230 not clogged, as it is in the 19A is shown, and therefore the pressure in it is lower than a predetermined pressure level, the steam does not overcome the elasticity force of the spring 520 , Accordingly, the opening / closing part closes 530 the steam flow channel connecting part 513 , with the result that no steam is discharged to the outside. However, if the steam hose 230 is clogged, as it is in the 19B is shown, and therefore the pressure in it exceeds the predetermined pressure level, for example 1 kgf / cm ² , the steam overcomes the elasticity force of the spring 520 , Accordingly, this becomes the vapor flow passage connecting part 513 closing opening / closing part 530 adjusted, with the result that the steam through the steam flow channel connecting part 513 and an external connection part 511 is discharged to the outside.

The following is with reference to the 20 an installation example for the components of a steam line, in particular with the steam generator according to the invention described.

At a predetermined position, in the clothes treating machine, a tray-type container (hereinafter referred to as "drawer") 700 attached, which can be inserted and pulled out. Preferably, the cartridge 300 in the drawer 700 appropriate. More precisely, the cartridge is 300 not directly with the connecting piece 480 connected. Instead, the cartridge is 300 in the drawer 700 attached, and this is inserted and pulled out to allow the cartridge 300 directly with the connecting piece 480 connected and disconnected from him.

Preferably, the drawer is located 700 at the front of the clothing treatment machine, for example at the control console 19 , More precisely, is at the back of the control panel 19 a holder 820 appropriate. The holder 820 is approximately parallel to an upper frame 830 arranged. On the holder 820 and the upper frame 830 is preferably a drawer slide 710 for guiding and holding the drawer 700 appropriate. More preferable is at a part of the top of the drawer slide 710 an upper guide 810 appropriate.

The top and one side (the front of the clothes treating machine) of the drawer slide 710 are open. The drawer 700 is through the side opening of the drawer slide 710 pushed in and pulled out. The connection piece 480 is at the top of the drawer slide 710 attached to the other side of the same.

As described above, it is preferable to the drawer 700 to be installed in the front of the clothes treating machine in consideration of skillful use. The 20 illustrates the control panel installed on the front cover of the clothes treating machine 19 , Accordingly, the drawer 700 in the control console 19 pushed in and pulled out of her. However, the invention is not limited to the above construction. For example, when the control panel is attached to the top cover of the clothes treating machine, as shown in FIG 1 is shown, the drawer can 700 be attached directly to the front cover of the clothing treatment machine.

If the cartridge 300 in the drawer 700 on the other hand, it is preferred that at least opposite sides of the cartridge 300 formally those of the drawer 700 match, causing the cartridge 300 tight with the drawer 700 connected is. On the opposite sides of the cartridge 300 are preferably concave parts 301 designed to allow a user to use the cartridge 300 in the drawer 700 to install and disconnect from it.

The following is a method for supplying water to the cartridge 300 with reference to the 20 described in detail.

When a user opens the drawer 700 also pulls out the cartridge 300 pulled out. In this state, the user disconnects the cartridge 300 from the drawer 700 , Then the user gives via the water supply opening, for example the first filter 330 , Water in the separated cartridge 300 so that it is filled with water. Then the user gives the cartridge filled with water 300 in the drawer 700 back, and he pushes them inside. As a result, the cartridge 300 automatically with the connecting piece 480 connected, and therefore the water in the cartridge flows to the pump 400 ,

After the use of the clothes treating machine is completed, the user can remove the cartridge 300 in the reverse order from the drawer 700 remove. According to the invention, the cartridge has 300 over the upper case 320 and the lower case 310 , Accordingly, the separated cartridge is simple and convenient 300 to clean.

As it is in the 21 is shown, the drawer can 700 on the other hand be used as a directly removable Wasserzuführquelle. When the drawer 700 is used as a directly removable water supply source, but may overflow due to lack of care of a user during the supply of water to her. This problem can be solved to some extent by the fact that the cartridge 300 is used as a removable Wasserzuführquelle. When the drawer 700 As a directly removable water supply source is used, it is possible the construction of the drawer 700 to simplify. The 21 For the sake of convenience of description, it will be understood that only the water softening element is shown 350 in the drawer 700 is appropriate. However, the invention is not limited to this construction. For example, the first filter can also be used 330 and the second filter 340 in the drawer 700 to be appropriate.

Hereinafter, a control method for the clothes treating machine according to the invention will be described with reference to FIGS 22 and 23 described.

The garment handling machine may generally operate in two modes of operation. An operating mode is for performing the original function of the clothes treating machine, i. H. the clothes drying process. The other mode of operation is to perform a process of removing wrinkles from clothes (hereinafter referred to as "finishing operation" for convenience). During the sizing process, it is possible to sterilize the clothes, remove odors from them, prevent the occurrence of static electricity in them, and fluff the clothes, in addition to removing wrinkles from them. A control method for the drying process generally includes a hot air supply step and a cooling step. These steps are also used in a conventional clothes treating machine, and therefore, a detailed description thereof will not be made. In particular, a control method for the finishing operation includes a steam supplying step which will be described in detail below.

The control method for a clothes treating machine includes, for the finishing operation, a steam supplying step (SS5) for supplying steam to the drum, and a hot air supplying step (SS7) for supplying hot air to the drum. Preferably, a drum heating step (SS3) is performed before the steam supplying step (SS5). Also, the finisher controlling method further includes a water supplying step (SS1) for supplying water to the steam generator to produce the steam required in the steam supplying step (SS5).

Preferably, the water supply step (SS1) is performed before the drum heating step (SS3). Also, the control method according to the invention preferably further includes a cooling step (SS9) for cooling the drum performed after the hot air supplying step (SS7). Preferably, the control method according to the invention further includes a water collecting step for discharging water remaining in the steam generator, i. H. the residual water in the steam generator, to the outside, which is performed after the steam supply step (SS5). (The water collection step will be described in detail below.) The drum can be heated using an additional heater installed in it; however, it is preferable to simply use the hot air heater.

Now, the respective control steps will be described in detail.

The drum heating step (SS3) is a step of heating the drum to a predetermined temperature, so that the removal of wrinkles from the clothes in the next step, i. H. in the steam supply step (SS5) can be carried out more effectively. The drum heating step (SS3) is for a predetermined period of time (T_pre - T_pump). The drum is rotated, preferably tumbled. More preferably, the drum is tumbled intermittently. Tumbling is a rotation of the drum at a speed of about 50 rpm. or less, so that the clothes do not adhere to the inner wall of the drum. Tumbling is well known in the art to which the invention pertains, and therefore no detailed description is provided thereon.

Preferably, the drum heating step (SS3) is started at a time when the water level in the steam generator reaches a high water level after water has been supplied to the steam generator for a predetermined period of time (T_pump). Also, the steam generator is preferably operated at a time when the drum heating step (SS3) is started. This is because steam is generated in a predetermined period of time after the operation of the steam heater.

Also, preferably, the end of the drum heating step (SS3) approximately coincides with the timing at which steam is generated. In fact, the drum heating step (SS3) preferably ends before supplying steam to the drum. This is because, when the drum is generated at the time when the steam is generated, ie, continuously heated in the steam supplying step (SS5), the inside temperature thereof is excessively increased, with the result that the steam supplied into the drum can vaporize to gas.

The steam supply step (SS5) is a step of supplying steam to the drum in such a manner that, in principle, the removal of wrinkles from clothes is carried out. The steam supply step (SS5) is executed for a predetermined period of time (T_steam). The drum is rotated, preferably tumbled. More preferably, the drum is tumbled intermittently. The time period (T_steam) for which the steam supply step (SS5) is executed is predetermined and made by experiments based on a factor such as the amount of an object to be dried. In the steam supply step (SS5), the water level in the steam generator decreases. Accordingly, water is preferably supplied to the steam generator when a low water level is detected. In this case, water can be continuously supplied to the steam generator until the high water level is detected. Preferably, however, water is supplied to the steam generator for a predetermined period of time before the water level in it reaches the high water level, for example, for about 3 seconds to increase the heating efficiency. When water is supplied to the steam generator until the water level in it reaches the high water level, it is necessary to heat a large amount of water. Accordingly, the supply of steam is interrupted for a predetermined period of time, and after the water boils, the supply of steam is resumed. However, if water is supplied to the steam generator for the predetermined period of time, for example 3 seconds, steam will be generated in about 1 second. Accordingly, it is possible to supply steam almost continuously into the drum.

Also, it is preferable that the tumbling in the steam supplying step (SS5) is performed intermittently and periodically, for example, about 3 seconds per minute. In the steam supply step (SS5), the drum can be tumbled continuously. In this case, however, the steam supplied into the drum may be intermittently discharged to the outside without being left in the drum. This is because the blower unit and the drum are simultaneously driven by a single motor, and therefore, when the drum rotates, the blower unit also operates to discharge steam from the drum. Accordingly, it is preferable to rotate the drum intermittently so that its rotation time in the steam supply step (SS5) is smaller than its stop time. Also, research carried out by the inventor of the present invention shows that the position of clothes in the drum continuously changed during the rotation thereof, whereas the clothes were approximately in the lower front of the drum, i. H. near the door, were placed when the drum was stopped. However, it is difficult to change the spraying direction of the nozzle, and therefore the nozzle is fixed so as to face the lower front side of the drum. For this reason, it is preferable that the clothes are placed in the spraying direction of the nozzle, i. H. at the lower front of the drum. Accordingly, it is preferable to control the drum to rotate for a short period of time so that the clothes can be placed in the spraying direction of the nozzle, and therefore, in the steam supplying step (SS7), a large amount of steam can be absorbed therein.

The hot-air supplying step (SS7) is a step in which hot air generated by the hot-air heater is supplied to the drum so that clothes which can be slightly wetted by the steam are dried again. The hot-air supplying step (SS7) is executed for a predetermined period of time (T_dry). The drum is not tumbled. The time period (T_dry) for which the hot-air supplying step (SS7) is executed is also predetermined and made by experiments based on a factor such as the amount of an object to be dried. It is preferable to discharge the water remaining in the steam generator to the cartridge after the hot air supplying step (SS7) is completed. The temperature of the residual water in the steam generator is high. Accordingly, the residual water in the steam generator is not discharged directly to the cartridge, but the discharge of the residual water in the steam generator is delayed for a predetermined period of time (T_delay). When the temperature in the steam generator is lower than a predetermined temperature (Temp_crit), the residual water in the steam generator is discharged to the cartridge. (Details are described below.)

The cooling step (SS9) is a step for cooling an object to be dried whose temperature has been raised in the hot air supplying step (SS7). The cooling step (SS9) is executed for a predetermined period of time (T_cooling). The drum is not tumbled. The time period (T_cooling) for which the cooling step (SS9) is performed is also predetermined and made by experiments based on a factor such as the amount of an object to be dried. Although cool air can be supplied to the drum in the cooling step (SS9), the temperature of the object is not too high. Accordingly, the Object as such for a predetermined period of time, which is simple but preferred.

Hereinafter, a method for controlling the pump with reference to the 22 and 23 described.

The pump control method according to the invention includes a water supply step (S100 and S200) for supplying water to the steam generator which generates steam to be supplied to the drum, and a water collecting step (S300) for collecting the water remaining in the steam generator. Of course, the water supply step (S100 and S200) preferably includes an initial water supply step (S100) and a water level maintenance step (S200) for maintaining the water level in the steam generator. On the other hand, the water collecting step (S300) is preferably performed by the pump. More preferably, the wet is collected into the removable water supply source connected to the steam generator.

Now the respective steps are described in detail.

As described above, the water supply step (S100 and S200) preferably includes the initial water supply step (S100) and the water level maintenance step (S200). The pump is rotated in the counterclockwise direction to deliver water to the steam generator (S1). When the water level in the steam generator reaches a high water level (S3), the pump is stopped and the steam heater is operated (S5).

When the steamer heater is operated, water is heated to generate steam. When the generated steam is released, the water in the steam generator decreases. Accordingly, the water level in the steam generator is detected, and when the water level in the steam generator reaches a low water level, the pump is rotated in the clockwise direction to supply water to the steam generator (S9 and S11). As already described, water can be continuously supplied to the steam generator until the high water level is detected. Preferably, however, water is supplied to the steam generator for a certain period of time, for example, about 3 seconds to increase the heating efficiency.

On the other hand, when the predetermined steam supply time period (T_steam) has elapsed (S7), the steamer heater is stopped (S13), and there is a delay by a predetermined period of time (T_delay). The reason why there is a delay by the predetermined time period (T_delay) is the maximum lowering of the temperature of the residual water in the steam generator. Subsequently, when the temperature in the steam generator is lower than a safety temperature (Temp_crit) (S17), the pump is rotated counterclockwise for a predetermined period of time, for example, about 30 seconds to collect the residual water from the steam generator (S25). However, if the temperature in the steam generator is higher than the safety temperature (Temp_crit), the frame is not collected directly from the steam generator but countermeasures are taken. For example, it is determined whether the water level in the steam generator is lower than the high water level (S19). If it is determined that the water level in the steam generator is lower than the high water level, the pump is rotated in the clockwise direction for a predetermined period of time, for example, about 5 seconds to supply water to the steam generator again (S21). On the other hand, when it is determined that the water level in the steam generator is not lower than the high water level, the temperature in it is compared with the safety temperature (Temp_crit) (S23). When the temperature in the steam generator is lower than the safety temperature (Temp_crit) (S23), the pump is rotated counterclockwise for a predetermined period of time, for example, about 30 seconds to collect the residual water from the steam generator (S25). On the other hand, when the temperature in the steam generator is higher than the safety temperature (Temp_crit), the procedure is ended without rotating the pump in the counterclockwise direction to collect the residual water from the steam generator (S27). Of course, the temperature in the steam generator may be compared to the safety temperature after a predetermined period of time has elapsed, and when the o. G. Condition is met, the residual water can be collected from the steam generator. Here, the safety temperature (Temp_crit) means the maximum temperature at which the reliability of the pump is maintained. For example, the safety temperature is about 60 degrees.

The water supply time (T_pump), the steam generation preparation time (T_pre), the steam supply time (T_steam), the drying time (T_dry), the cooling time (T_cooling), the delay time (T_delay), the tumble time and the pump operating time, as described in the 22 and 23 are illustrative examples, and the above times may be appropriately changed depending on the capacity of the clothes treating machine or the amount of an object to be dried.

Hereinafter, another embodiment of a control method for a Clothing treatment machine according to the invention with reference to the 24 described.

This embodiment is identical in its basic principle with the previous embodiment; however, this embodiment is designed to make the steam generation more efficient.

Steam is supplied to the drum in the steam feed step (SS5). However, even with the steam generator working, it takes time to boil water.

For this reason, steam is not generated directly. Accordingly, it is preferable to operate the steam generator before supplying steam to the drum. For safety's sake, however, it is preferable to operate the heater of the steam generator only when the water level in it has reached the low water level.

On the other hand, the timing at which the drum heating step (SS3) is started, d. H. the operation of the hot air heater is started after the operation of the steam generator. However, it is preferable to operate the hot air heater when the water level in the steam generator has reached the high water level, or when the heater of the steam generator is turned on, taking into account the heat capacity of the water in the steam generator.

The hot air heater can be operated at nominal power. However, it is preferable to operate the hot air heater with a power below the rated power. For example, if the rated power of the hot air heater is 5400 W, it is preferred to apply it to about half of it, that is, to about 50%. H. 2700 W to operate. This, since the heater of the steam generator is also operated in the drum heating step (SS3), therefore, when the hot air heater is operated at the rated power, it is required to increase the total power to be supplied to the clothes treating machine.

Meanwhile, the water supply step (SS1), i. H. the supply of water to the steam generator, generally finished when the water level in the steam generator reaches the high water level. However, it is preferable to perform the next step at a predetermined time, for example 90 seconds, after starting the supply of water, i. H. the operation start of the pump, regardless of whether the water level in the steam generator has reached the high water level or not, to execute compulsory. This is because when the high water level is not detected due to an abnormality of the steam generator, the water in it overflows into the drum. Accordingly, it is preferable to execute the next step after the lapse of the predetermined time.

Also, the drum heating step (SS3) is generally terminated when steam is generated by the steam generator. However, it is preferable to compulsorily execute the next step after a predetermined time, for example, 5 minutes. This, since it is preferable, although the probability that the hot air heater operates abnormally, is generally low to perform the next step for the sake of safety after the predetermined time. However, it is very difficult to clarify whether steam is generated by the steam generator. Accordingly, it is preferable that the drum heating step (SS3) is completed before steam is supplied into the drum.

Results of tests carried out by the inventor of the present invention showed that the finishing operation according to the invention had the effect of removing and preventing wrinkles on clothes, although depending on the types of clothes, for example, the types of materials for these and the like Hygroscopicity of the same, differences existed. An example of an object to be dried may be laundry which has been spin-dried by a washing machine. However, the object is not limited to laundry. For example, the invention is particularly useful when wrinkles on clothing worn for about a day, i. H. Apparel which has already been dried and slightly wrinkled are removed by the clothes treating machine according to the invention. In other words, the clothes treating machine according to the invention may be used as a type of wrinkle removing machine.

Hereinafter, another embodiment of a control method for a clothes treating machine according to the invention will be described with reference to FIGS 25 described.

As already described, the finishing operation according to the invention has the effect of removing wrinkles from clothes. In addition, the research carried out by the inventor of the present invention showed that the sizing operation showed, to some extent, the effect of sterilizing and fluffing the clothes. The operation of the clothes treating machine for performing this function basically includes the steam supplying step and the hot air supplying step (drying step). However, it is preferable to appropriately change the steam supply time and the hot air supply time depending on the purpose.

For example, the steam supply time and the hot air supply time are preferably longer when clothes are sterilized than when wrinkles are removed therefrom. On the other hand, the steam supply time and the hot air supply time are preferably shorter when garments are made fluffier than when wrinkles are removed therefrom. The optimum time may be set appropriately depending on experiments taking into account the amount of clothing.

The clothing treatment machine with the o. G. Structure and the associated control method show the following effects.

First, the invention has the effect of effectively preventing or removing wrinkles or creases on an object to be dried that has been dried. Also, the invention has the effect of sterilizing the object and removing odors from it.

Second, the invention has the effect of effectively removing wrinkles or wrinkles from dried clothes without ironing.
