In addition, preferably, the ledge 216 in the direction of the lower housing 212 on one side surface of the lower housing 212.

The device 220 prevent excessive water engaged by the ledge 216 so that the device 220 prevent excessive water does not fall too close to the bottom surface of the casing 210.

The device 220 prevent excessive water flow prevents the flow of excessive amounts of water supplied from the valve 104 water supply inside the casing 210 or unwanted leakage of contaminated water flowing from the drum 103, again through the hole 211a of the water supply. The device 220 prevent excessive water supply is installed in position in the casing 210 close to the hole 211a of the water.

The device 220 prevent excessive water supply is a float that moves vertically according to the quantity of water delivered to the inside of the casing 210 to open and close the opening 211a of the water.

The float includes a rib 221, which has the form of a diaphragm and installed vertically in the casing 210 so that the rib 221 is separated from the inner surface of the casing 210, and the switching element 222, which is placed between the rib 221 and the inner surface of the casing 210 and moves vertically according to the water level, the hearth is emeu inside the casing 210, to open and close the opening 211a of the water.

Preferably, the switching element 222 is made hollow in order to maximize buoyancy.

The rib 221 is used to direct the switching element 222, when the switching element 222 is moved vertically in the casing 210.

Preferably, the guide portion 221a is formed on both lateral ends of the ribs 221, thereby preventing the deviation of the switching element 222 from the path to the hole 211a of the water.

In addition, preferably, the guide portion 221a is curved so as to partially surround the switching element 222.

The rib 221 is installed perpendicularly from the upper surface of the housing 210 so that the lower end of the rib 221 is separated from the bottom surface of the casing 210.

The following describes, with reference to figure 4 and 5, the function of the steam generator 200 in accordance with the first embodiment.

As shown in figure 4, the switching element 222 down the ledge 216 switching element 222 due to load switching element 222.

In this state, the switching element 222 can move in all directions due to the inner surface of the casing 210, ribs 221 and the guide parts 221a formed on the rib 221.

I.e. switching element 222 rises vertically for MF is tons of buoyancy due to water supplied to the inside of the casing 210 or lowered vertically through the load switching element 222 when feedwater is reduced.

At the same time, as shown in figure 5, the switching element 222, which is supported by ledge 216 in the casing 210, gradually rises due to water continuously supplied to the inside of the casing 210.

The switching element 222 is raised to a position immediately under the hole 211a of the water supply and not fully closes the opening 211a of the water.

Then the sensor 213 water level senses that the water level in the casing 210 is the optimal water level, and the controller stops the supply of water from the valve 104 water supply.

However, if the sensor 213 water level does not work well in the above mode, despite the fact that the proper quantity of water delivered into the casing 210, the water supply is not interrupted and is always running.

Further, the amount of water supplied to the inside of the casing 210 increases, and the switching element 222 rises due to buoyancy and completely closes the opening 211a of the water.

Through this, despite the fact that the sensor 213 water supply is not functioning correctly, the water flow inside the casing 210 is terminated.

The device 220 prevent razmernoi water supply serves not only for to prevent excessive water flow into the housing 210 through the hole 211a of the water supply, but also prevents the flow of contaminated water, it is undesirable flowing out of the drum 103, the valve 104 water supply, is formed when the back pressure in the drum 103.

I.e. the amount of water in the casing 210 increases due to contaminated water, it is undesirable flowing through the exhaust hole 211b, and raises the switching element 222, thereby closing the hole 211a of the water.

Then, when the supply of adequate quantity of water inside the casing 210 is completed, as described above, the heater 215 mounted in the casing 210, heats the water in the casing 210 and constantly generates pairs.

The generated steam is produced inside of the drum 103 through the exhaust hole 211b and the pipe 106 steam.

Below is explained with reference to Fig.6 and 7, the steam generator device for washing clothes in accordance with the second embodiment of the present invention.

Part of the steam generator of the second variant of implementation for the most part the same position as illustrated by the first variant of implementation, unless the device to prevent excessive water flow. Part of the steam generator of the second variant of implementation, which are practically the same as in the first embodiment are denoted by the same reference position is, even when they are illustrated in other drawings, and a detailed description therefore is omitted because it is considered to be excessive.

The following describes the device to prevent excessive water supply, installed in the steam generator according to the second variant implementation.

As shown in Fig.6, the device 320 to prevent excessive water supply includes a switching element 321 for opening and closing the openings 211a water supply, the hinge 322 mounted on one side of the inner surface of the casing 210, and the rod 323 float, one end of which is mounted for rotation on the hinge 322 and the other end is connected with the switching element 321.

Preferably, the switching element 321 is hinged to the other end of the rod 323 float, so that the switching element 321 smoothly opened and closed the hole 211a of the water.

The following describes, with reference to Fig.7, the function of the steam generator 200 in accordance with the second embodiment.

When water is supplied into the housing 210 through the hole 211a water supply, surface water increases slowly.

When the water surface rises, the switching element 321, which is supported by ledge 216 in the casing 210, gradually rises due to buoyancy.

The switching element 321 is rotated with prices what risovaniem on the hinge 322, mounted on the inner surface of the casing 210, and slowly rises.

Then the sensor 213 water level senses that the water level in the casing 210 is the optimal water level, and the controller stops the supply of water from the valve 104 water supply.

When this switching element 321 does not close completely the hole 211a of the water.

However, if the water flow does not stop, but on an ongoing basis is due to incorrect operation of the sensor 213 water level, the switching element 321 rises due to buoyancy and completely closes the opening 211a of the water.

Through this it is possible to prevent an excessive flow of water inside the casing 210, and the water is released inside the drum 103 through the exhaust hole 211b.

Then, when the supply of adequate quantity of water inside the casing 210 is completed, as described above, the heater 215 mounted in the casing 210, heats the water in the casing 210 and constantly generates pairs.

The generated steam is produced inside of the drum 103 through the exhaust hole 211b and the pipe 106 steam.

Below is explained with reference to Fig and 9, the steam generator in accordance with a third embodiment of the present invention.

Part of the steam generator of the third variant of implementation, which is essentially the same as in the first and second versions of the implementation, the seat is raised by the same reference position, even when they are illustrated in other drawings, and a detailed description therefore is omitted because it is considered to be excessive.

The steam generator 200 includes a casing 210, which holds water and is equipped with a hole 211a of the water supply connected to the pipe 105 water supply, and an outlet hole 211b connected to the hole 106 of the steam supply, the heater 215 to heat water and the device 230 prevent back flow.

The device 230 prevent back flow prevents leakage of generated steam from the housing 210 in the valve 104 water supply.

Preferably, the device 230 prevent the reverse flow is a non-return valve in order to realize the flow of water in only one direction. More preferably, the device 230 prevent the reverse flow is established between the hole 211a of the water supply and the pipe 105 water supply.

The check valve includes a main body 231, forming the appearance of the check valve, and a switching device installed in the main body 231.

Switching device includes a pipe-like element 232 is provided with inlet hole 232a to transfer water supplied into the main body 231, to the hole 211a of the water supply, the protective element 233 to selectively protect the inlet openings 232a and the spring 234 to the elastic support is key protective element 233.

Preferably, the diameter of the inlet openings 232a pipe-like element 232 to transmit water is less than the diameter of the opposite ends of the pipe-like element 232.

As shown in Fig, a pipe-like element 232 is inclined so that the diameter of the pipe-like element 232 decreases from one end near the hole 211a of the water supply to the other end near the pipe 105 water supply.

This design allows a pipe-like element 232 evenly to cover the inlet hole 232a.

Preferably, the protective element 233 has a spherical shape, so that the protective element 233 on the inclined inner surface of the pipe-like element 232 selectively protects the inlet hole 232a.

Although not shown in the drawings, the check valve can be installed directly in the hole 211a water supply or pipe 105 water supply.

The following describes, with reference to Fig and 9, the function of the steam generator 200 in accordance with the third embodiment.

Fig illustrates the steam generator 200 in the mode in which water is supplied to the steam generator 200.

As shown in Fig, when water is supplied from the valve 104 of the water in the steam generator 200, the water passes through the check valve through the pipe 105 water supply and fit in the casing 210.

The protective element 233 is pushed to the hole 211a of the water flow due to the pressure the water, supplied from the valve 104 water supply, and thus opens the inlet opening 232a pipe-like element 232.

Thus, water is continuously fed from the valve 104 water flow inside the casing 210 through the hole 232a of the water.

After that, when water flow is stopped, as shown in Fig.9, the protective element 233 is returned to its original position by restoring force of the spring 234, supporting the protective element 233, and thereby closes the inlet hole 232a.

The heater 215 heats the water contained in the casing 210, thereby forming pairs. Steam is produced inside of the drum 103 through the exhaust hole 211b.

Steam continuously produced inside of the drum 103, and the temperature of the drum 103 is enhanced by a pair of high temperature.

Then the pressure in the drum 103 also increases, and may be formed with a back pressure to the steam generator 200.

If the back pressure is formed in the drum 103, the steam produced inside the drum 103, undesirable flows inside of the steam generator 200 through the pipe 106 steam.

The steam in the steam generator 200 is undesirable flows continuously to the valve 104 water supply through hole 211a of the water.

However, the device 230 prevent the reverse flow, i.e. the non-return valve, which is installed between the hole 211a of the water supply and the pipe 105 is filing water, blocking pairs and prevents the unwanted flow of steam to the valve 104 water supply, since the inlet opening 232a device 230 prevent the reverse flow is closed by a spherical protective element 233.

Below is illustrated with reference to figure 10-13, a steam generator in accordance with the fourth embodiment of the present invention.

As shown in figure 10, the steam generator 200 of the fourth version of the implementation, with which is connected the pipe 105 water supply and pipe 106 steam, installed in the housing 101 of the washing machine 100 with the drums.

Preferably, the steam generator 200 is mounted above the tank 102 so that the channel is connected between the valve 104 water supply and the pipe 106 steam has a relatively small extent, and the steam generator 200 is easily repaired and checked.

Part of the steam generator of the fourth version of the implementation, which is almost the same as in the first, second and third embodiment are denoted by the same reference positions, even when they are illustrated in other drawings, and a detailed description therefore is omitted because it is considered to be excessive.

The steam generator 200 includes a casing 210, which holds water and is equipped with a hole 211a of the water supply connected to the pipe 105 water supply, and an outlet hole 211b connected with what tertium 106 steam, the heater 215 for water heating and venting device 400.

The vent device 400 is used to let the steam out of the steam generator 200, is formed when excess pressure in the steam generator 200, the pipe 105 water supply and the pipe 106 steam due to steam, thereby eliminating excessive pressure. The vent device 400 is installed in the pipe 106 steam.

The vent device 400 includes an auxiliary pipe 410, the exhaust from the pipe 106 of steam supply, the bypass valve 420 mounted on the end of the auxiliary pipe 410, and a pipe 430 air outlet connected to the bypass valve 420.

Preferably, the end of the pipe 430 air vent for steam release is connected with the drain channel (not shown) of the device for washing Laundry with the steam generator 200, so that the steam produced out of the device for washing clothes.

The following describes, with reference to 11 and 13, the function of the steam generator 200 in accordance with the fourth embodiment.

11 illustrates the steam generator 200 in the mode in which water is supplied from the valve 104 water supply that is installed on the outside of the casing 210, the inside of the casing 210.

Water is supplied from the pipe 105 water supply connected to the valve 104 water supply inside the casing 210.

Then, when the proper amount of water is supplied to the inside of the casing 210, the sensor 213 water level (figure 4) measures the water level in the casing 210 and transmits the measured water level controller, and the controller stops the flow of water from the valve 104 water supply.

The heater 215 heats the water supplied to the inside of the casing 210, thereby forming pairs.

The following describes, with reference to Fig, the route of flow of steam generated from the steam generator 200.

As shown in Fig, steam is produced inside of the drum 103 through the pipe 106 steam.

The steam flows through a pipe 106 steam also flows through the auxiliary pipe 410 allocated from the pipe 106 steam.

Since the outlet 411 of the auxiliary pipe 410 is closed by-pass valve 420 is connected with the auxiliary pipe 410, the steam remains in the auxiliary pipe 410.

Then pairs formed from the housing 210, which is continuously produced inside the drum 103 through the pipe 106 steam.

Through the above-described iterative process, the temperature in the drum 103 is increased, and thus the pressure in the drum 103 also increases.

Thus, the back pressure to the pipe 106 steam is formed from the drum 103.

When the back pressure is generated, steam, which is released into the drum 103 through the pipe 106 steam, undesirable flows inside the casing 210.

In this case, steam is undesirable flows into the housing 210 through the pipe 106 steam and inside the auxiliary pipe 410, branched from the pipe 106 steam.

Total kolichestvoparkov in the casing 210 is increased, thereby forming the excess pressure in the steam generator 200.

Additionally, the total amount of steam in the pipe 106 steam and the pipe 105 water supply is increased, thereby forming the excess pressure in the pipe 106 steam and the pipe 105 water supply.

Then, as shown in Fig, pressure, having at least the specified intensity, is applied to the bypass valve 420, thereby opening the bypass valve 420.
