The node 400 controls the operation of each element in the washing machine and contains the element 410 select element 420 mode selector, element 430 choice pair and device 440 control.

With reference to figure 4 will be described node 400 of the control.

Element 420 selection mode is for user to select R the press of several modes. Element 420 mode selection may include dial design, such as a rotary switch 421 for supplying the selected signal after the mode is selected by turning the switch. That is, it is preferable mode is selected based on the angle and direction of rotation of rotary handle 421. Element 420 mode selection may be a touch panel.

The modes envisaged by item 420 selection mode, you can switch the type of fabric, such as wool, synthetic and linen, standard mode, the refreshing wash, wash tank/drum and sanitation mode. Mode refreshing wash is designed to remove wrinkles in linen through the use of steam. The method for performing the refreshing washing can be accomplished in several ways, and detailed explanation is omitted. Mode cleaning tank/drum designed for sterilization and washing tank/drum through steam without water in the drum. Modes is not limited, as shown in figure 4, and alternatively can be changed in accordance with a washing machine. For example, there may be added another wash cycle in accordance with the condition of damaged linen.

Preferably, when the supply of steam into the drum he turned. Turn means that the drum rotates the I at low speed, when linen does not stick to the inner wall of the drum under the action of centrifugal force. That is, the speed of rotation when rotating more IG (acceleration of free fall). The drum can be rotated clockwise/counterclockwise. On the other hand, preferably, in the alternative, to rotate the drum at a high speed greater than IG, and rotate the drum during the General modes of washing.

Element 410 option is used to control elements of each wash cycle and contains many buttons that supplies the selected signals to the device 440 of the control after the user clicks the buttons. For example, each button element 410 selecting may include at least one of the buttons, such as button 411 washing to select wash cycle button 41 rinsing to select the duration of the rinse button 413 speed for selecting the speed of rotation of the drum, button 414 temperature button 415 drying. It is preferable that was provided by the button 416 adjustment of steam for setting the various options (factors) form a pair. Button 416 adjustment of the pair can be considered as the element type of the option.

Although the element 410 ' option is not visible, the light turns off when the mode in which can be used in pairs, is selected in the control cell battery (included) is that 420 mode selection. Alternatively, instead of buttons, the term "button" is used only for convenience in this description.

That is, the operation of the steam generator 100 is optional in all kinds of modes of washing. For example, do not have to use pairs of modes wool and sheets/pillows as wool and sheets/pillows are heat sensitive. In addition, if the steam comes in contact with these types of tissues, the tissue can be damaged. Therefore, it is preferable to prevent such situations, the steam generator is not running when you run mode in which the operation of the steam generator is optional, although the user selects an item 430 choosing a pair.

Thus, in accordance with the present invention, the device 440 controls the steam generator to generate steam only when you entered the wash cycle is set mode, the washing mode of the washing with the use of steam (hereinafter, the mode of washing with steam).

The distinctive feature of this variant implementation, described above, can the t to be embodied in a variety of ways. For example, the select signal pair transmitted to the device 440 control only when the entered washing mode is a mode of washing with steam. Alternatively, even the select signal pair transmitted to the device 440 control regardless of whether the input mode of the washing mode of the washing with steam, and the select signal pair can be ignored when entered the wash cycle mode is not washing with steam.

In order to accurately describe below will indicate that the input signal is selected in item 430 steam, is passed to the device 440 control only when the entered washing mode is a mode of washing with steam.

In accordance with the present invention element 430 choice pair is selected in accordance with each mode of washing, the selected element 420 mode selection, which means that the device 440 control selectively connects with the element 430 choosing a pair.

Here the expression "selectively controlled" may mean that mechanical work element 430 choice pair is selectively and may also mean that the signal transmission between the element 430 choice pair and device 440 control is performed selectively, regardless of mechanical work element 430 choice pair, in the latter case, the signal transmission between the device 440 and control element 430 choice of the pair is activated in case when you have entered a regime of washing can wash with steam. While the signal transmission between the device 440 and control element 430 choice pair is terminated when the entered mode of washing is unable to perform washing with steam.

The device 440 control programmed to work only when the following two conditions are fulfilled. These two conditions are first condition when put the washing mode is a mode of washing with steam, is able to use the pair that is selected through a set of element selection mode, and the second condition when the selected selection item pair.

As mentioned above, the element 430 selecting a pair of selectively driven based on the selection element 420 selecting washing, and, in the alternative, the element 430 choice pair can be selectively operate on the basis of the selection element 410 of the option.

Another variant of implementation in accordance with the present invention will be described below.

The node 400 contains a control device 450 selection of washing with steam to notify the user that it is possible to choose an element 430 choice pair. Preferably, the device 450 selection of washing with steam uses light to be selectively activated/switched out.

The device 450 selection of washing with steam activated device 440 in the management in the case, when put the washing mode is a mode of washing with steam. When this mode of washing with steam may be at least one of the modes such as standard mode, refreshing washing and rinsing mode drum/tank.

The device 440 control node 400 controls the operation of the heater 110, and each valve 310 and 320 of the water supply on the basis of signals received from an element 430 choice pair. Alternatively, as described above, the device 440 control can read entered the wash cycle, the selected element 420 selection mode, and controls the device 450 selection of washing and leads him into action when the read mode of washing is a given mode of washing with steam. Although element 430 choice pair is selected, the steam generator 100 is controlled so as not to operate when the entered washing mode is a mode in which it is impossible to control the steam generator, as pre-installed.

Preferably the adjustment element pair are additionally provided for selecting at least one of the following parameters: time of start steam, steam, steam intensity and the time of the formation of steam. Of course, when regulated by several factors, the effectiveness of washing with the use of steam may be different, but the function of economy of the electric power can be performed.

The adjustment element pair can be used element 430 choice pair. It is preferable that was provided by the auxiliary adjusting device pair and could be a button 416 adjustment of steam. Button 416 may be a type of element 410 of the option.

The adjustment element pair can be adjusted different types of factors, preferably the amount of steam. For example, at least one of the following facts: economic steam, steam velocity, turnover and small pairs is selected in the adjustment element pair. In addition, when the mode pair, which requires a relatively large amount of steam, such as economic vapor and turbopro, it is preferable to control the steam generator until then, until the temperature in the drum reaches the preset temperature. In addition, when the mode pair, which requires a relatively small amount of steam, it is preferable to control the steam generator for a predetermined period of time. You can use the heater to heat water for washing as a heater for heating the drum. Alternatively, you can use other heaters.

Next will be described another variant implementation of the present invention.

Preferably, the element 420 choosing the modes was additionally provided with indicator 422 to notify the user about what mode of washing is a regime of washing with steam. Thus, the user may not have to worry, because he can recognize the mode of washing with steam.

The indicator 422 can be used in liquid crystal display, led and light bulb. Just notify the user by use of the term "STEAM"is provided on the control unit, as shown in figure 4. Preferably, on the surface of the control unit were printed letter "PAIRS".

In the node 400 control provided by the device 460 display washing with steam to notify the user that runs the Laundry with steam. Here, the device 460 display washing with steam may be a liquid crystal display and led, but preferably the bulb, switch on/shutting off during washing with steam.

With reference to figure 3-5 will describe the management process of the embodiment of the washing machine in accordance with the present invention.

Thus, the user can select the mode (S140). Along with this activates the signal transmission between the device 440 and control element 430 choice pair. Alternatively, as described above, it is always possible to transmit signals between the device 440 and control element 430 choice pair, and the select element 430 steam can be skipped device 440 control when a washing mode is not washing with steam.

On the other hand, when a washing mode is not washing with steam, light 450 is not enabled and the user does not need to choose an element 430 choice pair (S180). However, the user can select an item 430 choice pair. However, in accordance with the present invention, the signal that the selection item pair selected by the user, essentially, not citypulse, when a washing mode is not washing with steam. Here, it is preferable that the user has been notified that the choice of element 430 choice pair is not appropriate. For example, it displays an error message or a tone signal or a voice message).

The device 440 control checks, selects whether the user element 430 choice pair (S150). When the user has selected an item 430 steam, steam is supplied into the drum to perform the selected wash cycle with steam in accordance with a specified algorithm (S160).

For example, if the user selects the standard mode and the selection item pair, the device 440 controls a washing machine on the basis of the algorithm for the standard mode and generate steam. Unit 440 controls the drum (not shown), the valves 310 and 320 of the water supply and the heater 110 of the steam generator 100 to perform the appropriate mode. While it is preferable that the valve 320 water supply was the solenoid, and a switch was contact switch, selectively in contact with the end part of the power supply under the influence of device 440 control. More specifically, if the signal is washing with steam filed in item 430 of steam, the valve 320 of the water supply is regulated to supply a given quantity of water in the steam generator device 100 is istom 440 management through the channel 200 water supply. In addition, the switch is adjusted to supply power to the heater 110 of the steam generator 100 unit 440 controls. Here in the steam generator 100 includes a water level sensor for level measurement of water supplied. Thus, when the feed water level reaches a predetermined water level in the heater 110 are powered on. Alternatively, when the valve 320 water supply is opened to supply water to the steam generator 100 for a specified period of time, the electric power can be controlled for automatic feeding to the heater 110, the control unit 440.

Meanwhile, when the mode of washing with steam, the display 460 washing with steam provided in the node 400 control is activated to notify the user that runs the Laundry with steam.

When the user has not selected an item 430 choice pair, the washing mode is performed based on the given basic algorithm, that is, when the steam generator 100 is not regulated. When this display 460 washing with steam host 400 control is not activated to notify the user that washing with steam running.

After completion of the washing device 440 management are ready to test, selects whether the user is a new mode of washing after completion of the control.

Meanwhile, the node 400 control washing machine in accordance with aseason invention is not limited to its design and workflow options implementation described above. Then there is an element 430 choice pair may consist of one or more buttons that can be regulated by various manual operations, such as the timing of the beginning/end of the steam supply, steam supply, the time of steam supply. Of course, it is preferable to choose a variety of factors when wash cycle selected by the user, is one of the specified modes of washing with steam.

The method of controlling a washing machine in accordance with the present invention may not only be performed in the process described above.

For example, the user selects one of the modes of washing and establishes whether the selected mode of washing mode of the washing with the use of steam. Therefore, when the selected wash cycle can be used in pairs, the selection item pair is activated for selection. Then, when the user selects the selection item pair, can be washed with steam. That is directly evaluated whether the selected wash cycle to use steam without comparing the selected wash cycle with the specified mode to perform washing with steam. Of course, it is preferable that the standard mode was carried out despite the fact that the user has selected the selection item pair, if it is determined that the selected wash cycle is not the fast mode with the use of steam.

Although embodiments of described by including a washing machine, the present invention is not limited to this. For example, the present invention can be applied to the dryer, equipped with a steam generator.
