Meanwhile, Fig.7 depicts a view in cross section of the washing machine drum type with drying function according to the preferred embodiment of the present invention, illustrating another type of feeder pair.

As shown in figures 1 and 2, a washing machine drum type with drying function according to the preferred embodiment of the present invention includes a housing 100 forming the external appearance of the washing machine drum type with drying function, the valve 200 water supply, installed in the housing 100, to supply water from the outside of the washing machine drum type with drying function, essentially cylindrical tank 300 installed in the housing 100 with the inlet opening 310 for hot air and the exhaust port 320 for hot air dryer 400 mounted for rotation in the tank 300, inlet box 500, containing the drying heater 510 to heat the air to feed into the drum 400, and the fan 520 for forced hot air, heated drying heater 510, dryer, built into it, to supply hot air into the drum 400, and at least one 600 steam generator to supply steam into the drum 400.

As shown in Fig. 3-6, the steam generator 600 stereotypicaly node 610, having the space 611 for the passage of water, and the inlet opening 612 for water supply and the exhaust port 613, respectively connected to the space, the pipeline 620 for water supply, connecting the valve 200 water flow from the inlet opening 612 for supplying water steam generating node 610, the exhaust manifold 630 connecting the outlet 613 steam generating node 610 to the tank 300, the bypass pipe 660 connected to the pipeline 620 to supply water to drain excess water from the steam generating unit if water is supplied when the outlet and/or outlet pipe 630 is locked, and the heater 640 for quick heating of water, fed into the space 611 in the steam-generating node 610.

In addition, the steam generator 600 further comprises a temperature sensor (not shown) for registering the temperature of the steam generating node 610.

A temperature sensor is installed to control the heater 600 in accordance with the temperature of the steam generating node and, preferably, overheating of the heater 640 is prevented in advance through the use of a fuse, which must operate at temperatures above a predetermined temperature to turn off the energy supply to the heater 640.

Meanwhile, as shown in Fig. 4-6, as the adjacent node electrocute form the space 611 also has a tubular shape and the inlet opening 612 for water supply and the exhaust port 613 steam generating node 610 is formed on the opposite ends of the steam generating node 610.

Preferably, the steam-generating node 610 was tilted so that the outlet 613 was located above the inlet 612 for supplying water to prevent the release of water through the outlet 613, not a pair.

In this case, the space 611 steam generating node 610 has a cross sectional area that is greater than the cross-sectional area of the pipeline 620 for water or cross-sectional area of the exhaust pipe 630, to ensure a uniform supply of water in the space 611 steam generating node 610 and a more uniform release of steam from the space 611.

Preferably, the exhaust manifold 630 had a cross sectional area which is less than the cross-sectional area of the pipeline 620 to supply water.

It is necessary to create a differential pressure between the exhaust manifold 630 and pipeline 620 to supply water to ensure uniform steam release, generated with the passage of water delivered from the pipeline 620 to supply water through the space 611 steam generating node 610, into the exhaust manifold 630.

Between t the m preferably, the steam-generating node 610 is made of metal having good conductivity and low density, such as aluminum through pressure die casting.

The pipeline 620 to supply water contains valve 200 water flow (see figure 3), the pipe 621 to supply water that is connected with the water supply valve, and the pipe 622 for water supply connecting pipe 621 to supply water inlet hole 612 for supplying water steam generating node 610.

Exhaust manifold 630 contains exhaust pipe 632 connected to the outlet 613 steam generating node 610, and the pipe 631 steam connecting the exhaust pipe 632 with tank 300.

Preferably, the pipe 631 steam had an end 631a in the form of a nozzle for uniform steam.

Meanwhile, as shown in Fig.7, steam may be supplied into the drum 400 through the inlet duct 500 through the connection pipe 631 for vapor flow between the outlet 613 steam generating node 610 and the intake duct 500.

That is, the pipe 631 for a steam supply connected with the outlet 613 steam generating node 610 and the intake duct 500 to supply steam into the drum 400 through the inlet duct 500.

In this case, it is preferable that the end 631a for steam release pipe 631 steam was located on the side where the hot air comes out of the inlet duct 500

In addition, it is preferable that the blower is turned on 520 in the supply box 500, if steam is supplied from a pipe 631 for the supply of steam into the supply duct 500.

This is to prevent the passage of steam from the pipe 631 for vapor flow in the direction opposite to the direction of flow of hot air from the inlet duct 500.

If steam is supplied from a pipe 631 for the supply of steam into the supply duct 500 pairs in the supply box 500 may be supplied into the drum 400 hot air through the inclusion of the drying heater 510 simultaneously with turning on the fan 520 in the inlet duct 500.

Bypass pipeline 660 connects the pipeline 620 to supply water steam generating node 610 with tubing through which water for washing is supplied from the valve 200 water supply tank 300, for draining excess water from the adjacent node.

For example, if the exhaust port 613 and/or the exhaust pipe has frozen, blocking the passage due to the cold weather, or the steam release is uneven due to foreign substances, the bypass pipe 660 provides the passage of water from the adjacent node on the outer side of the pipeline to supply water to prevent the passage of water in the opposite direction towards the valve 200 in the water supply.

Meanwhile, as shown in figure 3, between CL the pan 200 water supply and tank 300 installed capacity for the detergent to mix water wash with detergent and feed tank 300. Preferably, the bypass pipe 660 was connected with tubing 710 for supplying water into the container for the detergent connecting capacity 700 detergent with valve 200 water flow.

That is, the bypass pipe 660 is connected between the pipeline 710 to supply water into the tank for detergent and pipe 621 for water supply pipeline 620 to supply water.

Bypass pipeline 660, pipe 621 for water supply pipeline 620 for water supply can be connected using a Y-shaped connector 900.

Y-shaped connector 900 may contain plot for the direction of the water flow, coupled with pipe 621 for water supply pipeline 620 for water supply, and bypass guide section 920, branched from the plot 910 to the direction of water flow, coupled with a bypass pipe 660.

Preferably, the bypass guide section 920 forked off from the site 910 for the direction of the water flow in the direction opposite to the direction of water flow pipe 621, for water supply pipeline 620 to supply water.

This is necessary for smooth passage of water into the bypass guide section 920 as a result of pressure differential between the area 910 to the direction of water flow and bypass guide section 920 in the middle of the reverse flow of water from the space 611 steam generating node 610 in the direction the structure to the Y-shaped connector 900.

Thus, it can be prevented the exit of the steam generator 600 of the present invention of the system in advance, as the water flowing in the opposite direction, can pass into the bypass pipe 660 connected to the pipeline 620 to supply water through a Y-shaped connector 900, even if the pipeline for steam release is locked.

Meanwhile, although not shown, the bypass pipe 660 can directly connect with a capacity of 700 detergent for the immediate passage of excessive amounts of water in the opposite direction from the space steam generating node 610 in the capacity 700 detergent.

As shown in Fig. 4-6, it is preferable that the heater 640 600 steam generator was the heater in the housing, molded for installation in steam-generating node 610 about space 611 for quick heating of the water passing into the space 611.

The heater 640 is installed in the steam-generating node 610, so that the heater 640 generates heat to quickly heat the steam generating node 610, made of aluminum, for heating the water passing into the space 611 steam generating node 610, to generate steam.

Meanwhile, as shown in figure 3, the steam generator 600 is installed with brackets 810 and 820 separately from the housing 100 forming the external appearance of the washing machine BA is Abednego type with drying function.

The body 100 of the washing machine drum type with drying function includes an additional frame 810, passing in the front/rear direction of the hull 100, the support bracket 820 on one side is attached to the secondary frame 810 on the front side, and steam-generating node 610 is connected with the other side of the support bracket 820 to install the steam generator 600 in the housing 100 of the washing machine drum type with drying function.

In this case, preferably, the steam-generating node 610 is fixed on the other side of the support bracket with screws.

That is, although not shown in detail, the steam-generating node 610 includes a mounting protrusions, respectively with the mounting holes on the top surface, and a bracket 820 fastening holes corresponding to the mounting tabs on the other side, and when the mounting holes and the screws are fixed in the mounting holes and mounting tabs, steam generating node 610 is connected with the supporting bracket 820.

For reference, additional frame 810 attached to the housing 100, increases the stability of the housing 100, resulting in reduced vibration and noise arising from the execution of a washing machine drum loop, like washing in the centrifuge.

Will be described the operation of the steam generator of the washing machine b is rebandage type with drying function.

Will be described the operation of the steam generator when performing a washing machine drum with the function of the drying cycle of the washing Laundry.

When the washing machine is a drum type with drying function starts the wash cycle, the water for washing and detergent are mixed in the vessel 700 for detergent and fed into the drum 400, and simultaneously turns on the 600 steam generator for supplying steam at a high temperature in the drum 400 through the tank 300.

That is, the flow of hot steam into the drum 400 at the initial stage of washing provides a uniform wetting underwear and separation of dirt, increasing the effect of washing even when a small amount of water for washing.

In this case, by switching on the fan 520 and the drying heater 510 to supply hot air into the drum 400 together with the steam rising temperatures in the drum 400 and heating water for washing, wetting underwear and separation of dirt can run faster and more efficiently.

Meanwhile, the steam generator 600 may supply water for washing in the drum 400 washing machine drum type with drying function instead of steam, reducing the time period of the cycle when washing or washing in the centrifuge.

Then, if you only need water for washing instead of steam, the steam generator 600 may include disabling the heater 640 to supply water for washing in the drum 400 through even prog nerator 600.

Accordingly, as the water for washing is supplied through two pipelines for water supply connected with the capacity of 700 detergent and steam generator 600, the time period for the reception of water for washing can be reduced, thus reducing the time period of the entire cycle.

Next will be described the operation of the steam generator, when the washing machine is a drum type with drying function loops drying clothes.

When the washing machine is a drum type with drying function begins to execute the cycle of drying, the drying heater 510 in the inlet duct 500 is energy and is driven fan 520 for generating the hot air inlet duct 500 and blowing hot air into the drum 400.

Simultaneously actuates the steam generator 600 for generating hot steam and hot steam into the drum 400 through the tank 300.

Then the hot air and hot steam generated thereby are fed into the drum 400 for drying clothes.

That is, during the drying hot air and hot steam are fed into the drum 400 to quickly raise the temperature in the drum 400.

Ultimately, the clothes in the drum 400 dries faster and is sterilized under the influence of hot steam, and under the influence of hot steam of his wrinkles are smoothed out, providing the effect regenerat is I.

Next will be described the operation of the steam generator, when the washing machine is a drum type with drying function performs a cycle different from the cycle of washing or drying.

If you assume a separate regeneration cycle for smoothing out wrinkles in linen and sterilization of linen, not washing and drying, the steam generator 600 generates hot steam and delivers it to the drum 400 through the tank 300.

That is, instead of washing or drying by submitting only the hot steam in lingerie in lingerie removes wrinkles and it is sterilized.

Ultimately, not only easy to minimize wrinkles on the clothes, but you can also get hygienically clean linen, which increases customer satisfaction.

Preferably, the steam generator worked during cycles of washing, drying or regeneration of running a washing machine a drum type with drying function, it is preferable that the drum 400 is rotated to ensure uniform supply of steam from the steam generator 600 in linen.

Meanwhile, if water is supplied to the steam generating node 610, when the exhaust port 613 and/or the exhaust manifold 830 blocked, the water passes from the steam generating node 610 in the capacity 700 detergent through the bypass pipe 660.

In accordance with this can be prevented by the reverse flow of excess water from the steam is generiruemogo node 610 in the direction of the valve 200 water supply and can be beforehand prevented the failure of the steam generating node 610 and the valve 200 water supply due to water pressure, passing in steam generating node 610 through the valve 200 in the water supply.

Specialists in the art will understand that various modifications and changes in the present invention without departing from the essence and scope of the present invention. Thus, it is understood that the present invention includes modifications and changes of the present invention provided that they are included in the scope of the attached claims and their equivalents.
