The display unit 120 includes a display panel 95 that is provided on the control panel 90 and displays operation information of the dishwasher 1. Specifically, the display panel 95 may display a cleaning zone in which a cleaning operation is performed among a plurality of cleaning zones, a cleaning course selected by the user, an estimated cleaning time, or a remaining cleaning time. The display panel 91 may be a liquid crystal display (LCD) panel, a light emitting diode (LED) panel, or an organic light emitting diode (OLED) panel.

The driving unit 140 drives the respective components included in the dishwasher 1 according to a control signal of the control unit 190 to be described later. More specifically, the driving unit 140 includes a driving circuit (not shown) for generating a driving current for driving the circulation pump 41, the drain pump 51, the distribution valve assembly 200, and the vane driving motor 520 .

For example, the drive 140 may include an H-bridge circuit (not shown) to drive the vane drive assembly 500 to move the vane assembly 400 in both directions.

The storage unit 150 stores programs and data for controlling the operation of the dishwasher 1, as well as a non-volatile memory (not shown) such as a magnetic disk, a solid-state disk, And a volatile memory (not shown) such as a D-RAM or an S-RAM for temporarily storing temporary data generated in the process of controlling the operation of the dishwasher 1.

The control unit 190 controls the operation of each configuration included in the dishwasher 1. The control unit 190 controls the circulation pump 41, the drain pump 51, the distribution valve assembly 200, and the vane drive motor 520 based on the user's operation command input through the input unit 110. [ And transmits the control signal to the driving unit 140.

The control unit 190 may include one or more microprocessors (not shown) for performing operations according to programs and data stored in the storage unit 150.

The dishwasher 1 may optionally include a position detector 130. That is, the position detector 130 is not an essential component.

The position detection unit 130 includes a position identification member 131 provided in the vane assembly 400 and a position detection sensor 132 that detects the position identification member 131.

The position identifying member 131 may be provided in the vane assembly 400.

The position identification member 131 may be attached to one end of the vane 410 or may be attached to the lower or upper surface of the vane holder 430 or may be attached to the lower or upper surface of the vane carrier 420. [ That is, it is preferable to attach to the vane assembly 400 and move with the vane assembly 400.

The position detecting sensor 132 is provided corresponding to the position of the position identifying member 131. [ It is preferable that the position detecting sensor 132 is located at a position where the position detecting sensor 132 does not move together with the vane assembly 400,

For example, when the position detecting sensor 132 is attached to one end of the vane 410 of the position identifying member 131, the position detecting sensor 132 may be mounted on the supporting rail 39 (see FIG. 5) The position detection sensor 132 may be installed on the upper surface of the vane holder 430 or the upper surface of the vane carrier 420. [

The position detecting sensor 132 is attached to the lower surface of the vane guide 510 or the lower surface of the tub 30 when the lower surface of the vane holder 430 of the position identifying member 131 or the lower surface of the vane carrier 420 is attached. .

In this way, the position detection sensor 132 can be positioned at any position where the magnetic field of the permanent magnet 152 can be sensed while the vane assembly 400 is moving. In other words, the position detection sensor 132 can be positioned anywhere on the moving path of the vane assembly 400. [

In addition, the position of the vane assembly 400, in which the position detection sensor 132 detects the magnetic field of the permanent magnet 152 during the movement path of the vane assembly 400, becomes the reference position.

For example, if the position identification member 131 is located in the vane holder 430 or the vane carrier 420 and the position detection sensor 132 is positioned near the rearmost of the vane guide 510, The reference position becomes the closest position to the last nozzle of the vane guide 510, that is, the fixed nozzle assembly 300.

When the position identification member 131 is positioned in the vane holder 430 or the vane carrier 420 and the position detection sensor 132 is positioned in the forefront of the vane guide 510, i.e., in the vicinity of the door 11, Is the foremost part of the vane guide 510.

Of course, the position detection sensor 132 may be located at any position on the movement path of the vane assembly 400. [ For example, the position detection sensor 132 may be located at the center of the vane guide 510. [

It is assumed that the position detection sensor 132 is located at one end of the vane guide 510, that is, at the rear end or the forefront of the vane guide 510. [ However, this is for the purpose of understanding, and is not limited thereto.

In addition, a total of two position detection sensors 132 may be provided at the rear end and the front end of the vane guide 510, respectively. In this case, the reference position may include a first reference position of a rear end of the guide rail 160 and a second reference position of a frontmost position of the guide rail 160.

The position detecting unit 130 includes the position identifying member 131 and the position detecting sensor 132. However, the present invention is not limited thereto.

The position identification member 131 may employ a permanent magnet that generates a magnetic field, and the position detection sensor 132 may employ a hall sensor that detects a magnetic field generated by the permanent magnet.

In addition, the position identification member 131 and the position detection sensor 132 may include a protrusion and a micro switch, a permanent magnet and a reed switch, an infrared sensor module, a capacitive proximity sensor, an ultrasonic sensor module, Sensors, and the like.

For example, when the position detector 130 includes a protrusion and a micro switch, the protrusion may be provided on a lower surface of the vane holder 430, and the micro switch may be provided on one side of the vane guide 510. When the vane assembly 400 is positioned at the reference position, the protrusion presses the microswitch, so that the position detector 130 can detect that the vane assembly 400 is positioned at the reference position.

Alternatively, when the position detector 130 includes an infrared sensor module, the infrared sensor module may be provided at one side of the vane guide 510. When the vane assembly 400 is positioned at the reference position, The infrared rays are reflected to the vane assembly 400, and the infrared sensor module can receive the reflected light. When the infrared sensor module receives the reflected light, the position detector 130 can detect that the vane assembly 400 is positioned at the reference position.

In addition, the position detecting unit 130 may include a capacitive proximity sensor for sensing a change in capacitance caused by the vane assembly 400, an ultrasonic sensor module for detecting ultrasonic waves, and a reflected wave reflected by the vane assembly 400 It is possible.

The dishwasher 1 includes a position detector 130 for detecting whether the vane assembly 400 is positioned at a reference position, but may not include the position detector 130.

For example, when the vane drive motor 520 is operated to move the vane assembly 400 toward one side of the vane guide 510, and the vane drive motor 520 is supplied to the vane drive motor 520 while the vane drive motor 520 is in operation It may be determined that the vane assembly 400 is positioned at the rear end of the vane guide 510 when the detected driving current is greater than or equal to a predetermined reference current.

The dishwasher 1 has the position identification member 131 and the position detection sensor 132 and defines the reference position for stable movement of the vane assembly 400. [ Specifically, the dishwasher 1 recognizes the position of the vane assembly 400 and moves the vane assembly 400 based on the position of the recognized vane assembly 400.

By defining the reference position using the position identification member 131 and the position detection sensor 132, the dishwasher 1 can recognize the position of the vane assembly 400, and the vane assembly 400 can recognize the position of the vane assembly 400, And the vane assembly 400 can be positioned at a predetermined position.

In other words, the reference position may be a reference point for movement of the vane assembly 400. [ Specifically, the dishwasher 1 can calculate the position of the vane assembly 400 by moving the vane assembly 400 with respect to the reference position.

For example, in order to position the vane assembly 400 in a specific position, the dishwasher 1 may move the vane assembly 400 to a desired position by moving the vane assembly 400 relative to the reference position have.

For this reason, when the washing or rinsing cycle of the dishwasher 1 is started or ended, the dishwasher 1 places the vane assembly 400 in the reference position. That is, the reference position may be a position at which the vane assembly 400 starts to move and a position at which the vane assembly 400 ends the movement.

The configuration of the dishwasher according to one embodiment has been described above.

Hereinafter, the configuration of the dish washer according to another embodiment will be described. The same identification numbers are used for the same configurations as those shown in Figs. 1 to 10.

Fig. 11 shows a dishwasher according to another embodiment, and Fig. 12 shows a lower portion of the dishwasher according to another embodiment.

First, a schematic configuration of the dish washer will be described with reference to Figs. 11 and 12. Fig.

The dishwasher 1 includes a main body 10 forming an outer appearance, a tub 30 provided inside the main body 10, baskets 22a and 22b provided inside the tub 30 for accommodating the dishes, And the fixed nozzle assembly 300 for discharging the washing water and the washing water from the nozzle 43 for storing the washing water and the washing water from the nozzle 43 into the rotary type spray nozzles 61 and 63 and the fixed nozzle assembly A dispensing valve assembly 200 for dispensing the washing water to the rotary spray nozzles 61 and 63 and the fixed nozzle assembly 300 and the washing water of the faucet 43 to the main body 300 together with the dirt, A vane assembly 400 for moving the inside of the tub 30 to reflect the washing water to the table and a vane driving assembly 500 for driving the vane assembly 400, .

The tub 30 may have a box shape whose front is opened so that the tableware can be inserted and removed. The front opening of the tub 30 can be opened and closed by the door 11. [ The tub 30 may have a top wall 31, a rear wall 32, a left wall 33, a right wall 34 and a bottom plate 35.

The baskets 22a and 22b may be wire racks made of wires so that the washing water can pass without being washed. The baskets 22a and 22b may be detachably provided inside the tub. The baskets 22a and 22b may include an upper basket 22a disposed at an upper portion of the tub 30 and a lower basket 22b disposed at a lower portion of the tub 30. [

The rotary injection nozzles 61 and 63 inject the washing water through the injection holes 62 and 64 formed in the upper rotary nozzle 61 and the intermediate rotary nozzle 63 and rotate by the reaction due to the injection of the washing water.

The fixed nozzle assembly 300 is provided at a lower portion of the tub 30 and is fixed to one side of the tub 30 so as not to move unlike the rotary type injection nozzles 61 and 63. The fixed nozzle assembly 300 is disposed adjacent to the rear wall 32 of the tub 30 and is capable of spraying wash water toward the front of the tub 30. Therefore, the washing water injected from the fixed nozzle assembly 300 may not directly direct to the tableware.

The fixed nozzle assembly 300 may include a left fixed nozzle 330 disposed on the left side of the tub 30 and a right fixed nozzle 340 disposed on the right side of the tub 30. [

The vane assembly 400 may include a vane 410 extending in the lateral direction of the tub 30 so as to reflect all of the washing water sprayed from the fixed nozzle assembly 300. Such a vane 410 can linearly reciprocate along the spraying direction of the washing water sprayed from the fixed nozzle assembly 300. That is, the vane 410 can linearly reciprocate along the front-back direction of the tub 30. [

Accordingly, the linear spray structure including the fixed nozzle assembly 300 and the vane assembly 400 can clean the entire area of the tub 30 without a dead zone.

The dispensing valve assembly 200 dispenses wash water so that the rotatable spray nozzles 61, 63 and the stationary nozzle assembly 300 can spray the wash water independently of each other. Further, the dispensing valve assembly 200 distributes the washing water so that the left fixed nozzle 330 and the right fixed nozzle 340 of the fixed nozzle assembly 300 can also independently spray the washing water.

Thus, the dishwasher can independently clean the left and right sides of the tub 30 separately. Of course, unlike the other embodiment, it is needless to say that it is not necessarily divided into the left side and the right side, but it can be divided into more subdivisions as necessary.

Hereinafter, the main structure of the dishwasher according to another embodiment will be described in order.

In addition, in the third dispense mode, the dispense valve assembly 200 supplies washing water only to the left fixed nozzle 330 and the right fixed nozzle 340 through the first hose 271a and the third hose 271c, In the 4-split mode, the dispense valve assembly 200 can only supply the wash water to the left fixed nozzle 330 through the first hose 271a.

The washing water dispensed to the rotary spray nozzles 61 and 63 is sprayed toward the tableware by the rotary spray nozzles 61 and 63 to wash the tableware. The washing water distributed to the left fixed nozzle 330 and the right fixed nozzle 340 is sprayed toward the vane assembly 400 by the left fixed nozzle 330 and the right fixed nozzle 340, So that the tableware can be cleaned.

The washing water from which the tableware is washed is accommodated in the jaws 43 again.

Thus, the washing water circulates through the jaws 43, the circulation pump 41, the dispensing valve assembly 200, the rotary injection nozzles 61 and 63, and the fixed nozzle assembly 300.

The storage unit 150 stores programs and data for controlling the operation of the dishwasher 1, as well as a non-volatile memory (not shown) such as a magnetic disk, a solid-state disk, And a volatile memory (not shown) such as a D-RAM or an S-RAM for temporarily storing temporary data generated in the process of controlling the operation of the dishwasher 1.

The control unit 190 controls the operation of the configuration included in the dishwasher 1. Specifically, the control unit 190 outputs a control signal for controlling the vane drive motor 520, the circulation pump 41, and the drain pump 51 based on the control command input through the input unit 110.

The control unit 190 may include one or more microprocessors (not shown) for performing operations according to programs and data stored in the storage unit 150.

In addition, the dishwasher 1 may optionally include a position detector 130 for detecting the position of the vane assembly 400 (see FIG. 11).

22 and 23 show an example of a position detector included in the dishwasher according to another embodiment, and FIGS. 24 and 25 show another example of the position detector included in the dishwasher according to another embodiment Respectively.

The position detecting unit 130 may include a position identifying member 131 attached to the vane assembly 400 and a position detecting sensor 132 detecting the position identifying member 131. [

When the position detection sensor 132 detects the position identification member 131, the position detection unit 130 can determine that the vane assembly 400 is positioned at the same position as the position detection sensor 132.

For example, the position identifying member 131 may be attached to the lower surface of the vane holder 430. [ An identification member cover 435 may be provided to protect the position identification member 131. [ The identification member cover 435 prevents the position identification member 131 from contacting the washing water.

The position detection sensor 132 may be provided near the fixed nozzle assembly 300 as shown in FIG.

Specifically, the position detection sensor 132 may be provided inside the tub penetration portion 630 of the bottom plate cover 600. [ That is, the position detection sensor 132 may be provided inside the tub penetration part 630 exposed to the outside of the tub 30 together with the vane drive motor 520.

The position detection unit 130 may further include an auxiliary position detection sensor 133. [

The sub-position detecting sensor 133 may be located at various positions other than the first position P1. For example, the sub-position detecting sensor 133 may be located on the bottom plate 35 of the tub 30 as shown in Figs.

The auxiliary position detection sensor 133 may be positioned on the opposite side of the fixed nozzle assembly 300 when the position detection sensor 132 is positioned near the fixed nozzle assembly 132. [ In other words, the sub-position detecting sensor 133 may be disposed at a position corresponding to the position identifying member 131 when the vane assembly 400 is located farthest from the fixed nozzle assembly 300.

In addition, the position identification member 131 and the position detection sensors 132 and 133 may be located at various positions.

The position identifying member 131 can be located at various positions such as the vane carrier 420, the central portion of the vane 410, and both ends of the vane 410 as well as being located in the vane holder 430. [

The position detection sensor 132 and the auxiliary position detection sensor 133 may be located at various positions depending on the position of the position identification member 131. [ 14), the bottom plate 35 of the tub 30, the rear holder 512 (see Fig. 14) or the front holder 513 (see Fig. 14) ). ≪ / RTI >

In addition, the position detection sensor 132 may be located proximate to the stationary nozzle assembly 400, as well as located away from the stationary nozzle assembly 400. The sub-position detection sensor 133 may also be located near the stationary nozzle assembly 400 as well as at a location remote from the stationary nozzle assembly 400.

However, it is assumed that the position detection sensor 132 is located at the first position P1 and the auxiliary position detection sensor 133 is located at the second position for the sake of understanding. Where the first position Pl is the position of the vane assembly 400 when the vane assembly 400 is maximally close to the stationary nozzle assembly 300. The second position P2 also refers to the position of the vane assembly 400 when the vane assembly 400 is farthest away from the stationary nozzle assembly 300.

In this case, when the position detecting sensor 132 detects the position identifying member 131, the dishwasher 1 can determine that the vane assembly 400 is located at the first position P1, When the sensor 133 detects the position identifying member 131, the dishwasher 1 can determine that the vane assembly 400 is located at the second position.

The position detection unit 130 is not limited to the position detection sensor 131 located at the first position P1 and the auxiliary position detection sensor 133 located at the second position P2, And a position detection sensor positioned at a position other than the first position P1 and the second position P2.

For example, the position detection unit 130 may further include a position detection sensor installed at a position near the center of the first position P1 and the second position P2. In addition, the position detection unit 130 may further include a plurality of position detection sensors disposed at regular intervals between the first position P1 and the second position P2.

The position identification member 131 and the position detection sensor 132 may employ a permanent magnet and a Hall sensor, respectively. That is, the Hall sensor for detecting the magnetic field can detect the position of the vane assembly 400 by detecting the magnetic field by the permanent magnet.

In addition, the position identification member 131 and the position detection sensor 132 may include a micro switch that is pressed by the protrusions and protrusions protruding from the vane assembly 400, an infrared light source that emits infrared rays, and an infrared sensor that detects infrared rays .

Specifically, when the protrusion formed on the vane assembly 400 presses the micro switch installed at the first position P1, the dishwasher 1 determines that the vane assembly 400 is located at the first position P1 .

When the infrared sensor installed at the first position P1 senses the infrared ray emitted from the infrared light source attached to the vane assembly 400, the dishwasher 1 can detect that the vane assembly 400 is positioned at the first position P1 .

In addition, the position detection unit 130 may include only the position detection sensor 132.

For example, the position detection sensor 132 may include a capacitive proximity sensor for detecting a change in capacitance caused by the vane assembly 400, an ultrasonic sensor module for transmitting ultrasonic waves and receiving ultrasonic waves reflected from the vane assembly 400, An infrared sensor module that emits infrared rays and receives infrared rays reflected by the vane assembly 400 may be employed.

When the position detecting unit 130 includes a capacitive proximity sensor disposed at the first position P1, when the capacitive proximity sensor senses a change in capacitance caused by the vane assembly 400, It can be determined that the first switch 400 is located at the first position.

Specifically, when the ultrasonic sensor module installed at the first position Pl detects the ultrasonic waves reflected by the vane assembly 400, the dishwasher 1 can detect that the vane assembly 400 is in the first position It can be judged that it is located.

When the infrared sensor module installed in the first position P1 of the position detection unit 130 senses the infrared ray reflected by the vane assembly 400, the dishwasher 1 can detect that the vane assembly 400 is positioned at the first position .

The position detection unit 130 may include a position detection sensor that moves together with the vane assembly 400.

For example, the vane assembly 400 is provided with a pressure sensor for detecting the pressure of the washing water injected by the fixed nozzle assembly 400, and the dishwasher 1 is connected to the vane assembly 400 according to the pressure of the washing water detected. Can be determined.

In addition, an infrared distance sensor module including an infrared ray emitting unit for emitting infrared ray and an infrared ray receiving unit for receiving infrared ray is installed in the vane assembly 400, and the emitted infrared ray is reflected on the stationary nozzle assembly 300 or the door 11 The position of the vane assembly 400 can be calculated based on the time of flight (TOF).

In addition, an ultrasonic distance sensor module including an ultrasonic wave transmitting part for transmitting ultrasonic waves and an ultrasonic receiving part for receiving ultrasonic waves is installed in the vane assembly 400, and the transmitted ultrasonic waves are reflected on the fixed nozzle assembly 300 or the door 11 The position of the vane assembly 400 can be calculated based on the time of flight (TOF).

It is assumed here that the position identification member 131 is provided in the vane assembly 400 and the position detection sensors 132 and 133 are installed in the first position P1 or the second position P1 .

Hereinafter, the operation of the dishwasher, particularly, the operation of the linear washing unit will be described. First, the overall operation of the dishwasher will be described.

The dishwasher 1 can perform a water supply stroke, a cleaning stroke, a drainage stroke, and a drying stroke.

In the water supply stroke, the washing water can be supplied into the tub 30 through the water supply pipe (not shown). The washing water supplied to the tub 30 flows into the buff 43 provided at the lower portion of the tub 30 by the gradient of the bottom of the tub 30 and can be stored in the buff 43. [

In the cleaning stroke, the circulation pump 41 can be operated to pump the washing water of the shaft 43. The wash water pumped by the circulation pump 41 may be distributed to the rotatable spray nozzles 61 and 63, the left fixed nozzle 330 and the right fixed nozzle 340 through the distribution valve assembly 200.

The washing water sprayed from the rotary spray nozzles 61 and 63 and the fixed nozzle assembly 300 strikes the dishes and removes dirt adhering to the dishes and drops along with the dirt and can be stored in the buff 43 again. The circulation pump 41 pumps the circulating water stored in the pump 43 again. During the cleaning stroke, the circulation pump 41 can be repeatedly operated and stopped. In this process, the dirt dropped by the damper 43 together with the washing water is collected by the filter mounted on the damper 43 and remains in the damper 43 without circulation.

Next, a movement operation of the vane assembly 400 will be described.

One end adjacent to the stationary nozzle assembly 300 at the opposite ends of the vane guide 510 is referred to as a first position and the opposite side of the stationary nozzle assembly 300 is referred to as a second position. It is assumed that the position detection sensor 131 is located at the first position. That is, the first position becomes the reference position.

A direction in which the vane assembly 400 moves toward a first position at an arbitrary position of the vane guide 520 is referred to as a first moving direction and a direction in which the vane assembly 400 moves Is referred to as a second moving direction.

26 illustrates a vane movement control method according to an embodiment of a vane movement direction matching operation.

The dishwasher 1 moves the vane assembly 400 by the rotation of the vane driving motor 520. At this time, the dishwasher 1 performs a vane moving direction matching operation 1000 between the rotating direction of the vane driving motor 520 and the moving direction of the vane assembly 400.

For example, when the vane driving motor 520 rotates in the clockwise direction, it is determined whether the vane assembly 400 moves in the first direction or the second direction, and when the vane driving motor 520 rotates counterclockwise It determines whether the vane assembly 400 moves in the first direction or in the second direction.

The vane movement direction matching operation 1000 will be described with reference to FIG.

First, the dishwasher 1 drives the vane driving motor 520 in a clockwise direction for a first time (1010).

Here, the first time is equal to or longer than a time (hereinafter referred to as "first reference time") when the vane assembly 400 moves between the first position and the second position by the vane drive motor 520 It means time. In other words, when the vane drive motor 520 is driven for the first time, the vane assembly 400 located at any position of the vane guide 510 is moved to the first position or the second position.

Then, the dishwasher 1 determines whether the vane assembly 400 is located at the first position (1020). Specifically, the dishwasher 1 judges whether the position detecting sensor 132 located at the first position has detected the position identifying member 131 attached to the vane assembly 400.

For example, when the position identification sensor 132 detects the position identification member 131, the dishwasher 1 determines that the vane assembly 400 is located at the first position, and when the position identification sensor 132 determines that the position If the identification member 131 is not detected, the dishwasher 1 judges that the vane assembly 400 is not positioned at the first position.

If the vane assembly 1 is in the first position (example of 1020), the dishwasher 1 sets the clockwise direction to the first rotational direction (1030).

The first rotational direction means the rotational direction of the vane drive motor 520 for moving the vane assembly 400 in the first movement direction. In other words, when the vane drive motor 520 is driven in the first rotational direction, the vane assembly 400 moves toward the first position.

Further, the dishwasher 1 sets the counterclockwise direction to the second rotational direction (1040).

The second rotational direction refers to the rotational direction of the vane drive motor 520 that moves the vane assembly 400 in the second movement direction. In other words, when the vane driving motor 520 is driven in the second rotational direction, the vane assembly 400 moves toward the second position.

If the vane assembly 1 is not in the first position (NO in 1020), the dishwasher 1 sets the clockwise direction to the second rotational direction (1050).

Further, the dishwasher 1 sets the counterclockwise direction to the first rotational direction (1060).

Through the vane movement direction matching operation 1000, the dishwasher 1 can match the rotating direction of the vane driving motor 520 with the moving direction of the vane assembly 400.

27 and 28 illustrate a vane movement control method according to the vane initializing operation according to an embodiment.

The vane initializing operation 1100 for moving the vane assembly 400 to the first position (reference position) is performed at the start of the water supply stroke or the cleaning stroke.

Through the vane initialization operation 1100, the dishwasher 1 can calculate the position of the vane assembly 400 during movement of the vane assembly 400.

By moving the vane assembly 400 in the vicinity of the fixed nozzle assembly 300, it is possible to prevent the washing water from dropping onto the bottom plate 35 of the tub 30 when the fixed nozzle assembly 300 starts spraying the washing water have.

The vane initializing operation 1100 will be described with reference to FIGS. 27 and 28. FIG.

First, the dishwasher 1 judges whether a water supply or cleaning operation has started (1110).

When the water supply or washing cycle is started, the dishwasher 1 determines whether the vane assembly 400 is located at the first position P1 (620). Specifically, the dishwasher 1 judges whether the position detecting sensor 132 located at the first position Pl detects the position identifying member 131 attached to the vane assembly 400. In this case,

As described above, the first position P1 is a position at which the vane assembly 400 is moved. In other words, the dishwasher 1 can locate the vane assembly 400 based on the distance that the vane assembly 400 has moved from the first position P1. For this reason, the dishwasher 1 judges that the vane assembly 400 is located at the first position Pl to place the vane assembly 400 in the first position Pl.

If the vane assembly 400 is in the first position Pl (example of 1120), the dishwasher 1 terminates the vane initialization operation 1100 to the vane assembly 400.

If the vane assembly 400 is not located at the first position Pl (No at 1120), the dishwasher 1 moves the vane assembly 400 in the first moving direction (1130). Specifically, the dishwasher 1 drives the vane driving motor 520 in the first rotational direction.

While the vane assembly 400 is moving in the first moving direction, the dishwasher 1 uses the position detector 130 to determine whether the vane assembly 400 is located at the first position Pl.

When the vane assembly 400 is positioned at the first position Pl as shown in Fig. 28, the movement of the vane assembly 400 is stopped.

Through the vane initializing operation 1100, the dishwasher 1 can place the vane assembly 400 in the first position P1.

27 and 28, when the dishwasher 1 includes the position detecting unit 130, the vane initializing operation has been described.

The dishwasher 1 can move the vane assembly 400 to the first position even when the position detector 130 is not included.

For example, the dishwasher 1 can position the vane assembly 400 in the first position by driving the vane drive motor 520 in the first rotational direction for a first time.

As described above, the first time may be equal to or longer than the first reference time, which is the time during which the vane assembly 400 moves between the first position and the second position, or may be longer than the first reference time. In other words, when the vane driving motor 520 is driven in the first rotational direction for the first time, the vane assembly 400 located at any position of the vane guide 510 is moved to the first position.

In another example, when the vane drive motor 520 includes an encoder, the dishwasher 1 may be configured such that the distance between the first and second positions of the vane assembly 400 (hereinafter referred to as "first reference distance" ) Of the vane drive motor 520 in the first rotation direction.

FIG. 29 shows a vane movement control method according to another embodiment of the vane initializing operation.

26 illustrates the vane movement direction matching operation 1000, and FIGS. 27 and 28 illustrate the vane initialization operation 1100. FIG. 29, a description will be given of the simultaneous execution of the vane movement direction matching operation 1000 and the vane initialization operation 1100. FIG.

The vane initialization operation 1200 will now be described with reference to FIG.

First, the dishwasher 1 drives the vane driving motor 520 in a clockwise direction for a first time (1210). Here, the first time is equal to or longer than a time (hereinafter referred to as "first reference time") when the vane assembly 400 moves between the first position and the second position by the vane drive motor 520 It means time.

Then, the dishwasher 1 determines whether the vane assembly 400 is located at the first position (1220). Specifically, the dishwasher 1 judges whether the position detecting sensor 132 located at the first position has detected the position identifying member 131 attached to the vane assembly 400.

When the vane assembly 1 is in the first position (example of 1220), the dishwasher 1 sets the clockwise direction to the first rotational direction and the counterclockwise direction to the second rotational direction (1230).

If the vane assembly 1 is not in the first position (NO in 1220), the dishwasher 1 sets the clockwise direction to the second rotational direction and sets the counterclockwise direction to the first rotational direction (1240) .

Then, the dishwasher 1 drives the vane driving motor 520 counterclockwise for a first time (1250).

When the vane drive motor 520 is driven in the clockwise direction for the first time, the vane assembly 400 is located at the first position or the second position. If the vane assembly 400 is not positioned at the first position, the dishwasher 1 is to be positioned at the second position. Therefore, the dishwasher 1 may drive the vane driving motor 520 in the counterclockwise direction for a first time, In the first position.

FIGS. 30 and 31 illustrate a vane movement control method according to an overall cleaning operation according to an embodiment.

The entire cleaning operation 1300 will be described with reference to FIGS. 30 and 31. FIG.

First, the dishwasher 1 moves the vane assembly 400 in the second moving direction D2 (1310). The second movement direction D2 means the direction from the arbitrary position of the vane guide 510 to the second position P2. Specifically, in order to move the vane assembly 400 in the second moving direction D2, the dishwasher 1 may drive the vane driving motor 520 in the second rotational direction.

Thereafter, the dishwasher 1 determines 1320 whether the vane assembly 400 has reached the second position P2.

The second position P2 means one end of the vane guide 510 through which the vane assembly 400 moves. For example, the second position P2 may be the opposite end of the stationary nozzle assembly 300 at either end of the vane guide 510. [

The dishwasher 1 can judge in various ways whether the vane assembly 400 has reached the second position P2.

For example, the dishwasher 1 may determine whether the vane assembly 400 has reached the second position P2 based on the operating time of the vane drive motor 520. [

By dividing the distance (hereinafter referred to as "first reference distance") between the first position P1 and the second position P2 by the moving speed of the vane assembly 400, the vane assembly moves the first reference distance (Hereinafter, referred to as "first reference time"). Here, the moving speed of the vane assembly 400 is calculated based on the rotational speed of the vane drive motor 520 (see Fig. 4).

The dishwasher 1 can determine whether the vane assembly 400 has reached the second position P2 according to whether the time when the vane driving motor is driven in the second rotational direction is equal to or longer than the first reference time.

More specifically, when the time when the vane driving motor 520 is operated in the second rotation direction is equal to or longer than the first reference time, the dishwasher 1 determines that the vane assembly 400 has reached the second position P2, When the time when the vane driving motor 520 operates in the second rotational direction is less than the first reference time, the dishwasher 1 judges that the vane assembly 400 has not reached the second position P2.

As another example, the dishwasher 1 may determine whether the vane assembly 400 has reached the second position P2 based on the rotational displacement of the vane drive motor 520.

When the vane drive motor 520 (see Fig. 4) includes an encoder for detecting the rotational displacement, the dishwasher 1 calculates the moving distance of the vane assembly 400 by the operation of the vane drive motor 520 Can be calculated. Specifically, the movement distance of the vane assembly 400 can be calculated based on the product of the rotational displacement of the vane drive motor 520 detected by the encoder and the radius of the drive pulley 530.

The dishwasher 1 is moved to the second position (the second position) in accordance with whether the product of the rotational displacement of the vane driving motor 520 in the second rotational direction and the radius of the driving pulley 530 is greater than a first reference distance P2), as shown in FIG.

Specifically, if the product of the rotational displacement of the vane drive motor 520 in the second rotational direction and the radius of the drive pulley 530 is equal to or greater than the first reference distance, the dishwasher 1 can move the vane assembly 400 to the second position (P2) is reached. If the product of the rotational displacement of the vane drive motor 520 in the second rotational direction and the radius of the drive pulley 530 is less than the first reference distance, the dishwasher 1 can move the vane assembly 400 to the second position P2). ≪ / RTI >

As another example, when the position detecting section 130 includes the sub-position detecting sensor located at the second position P2, it is determined whether the sub-position detecting sensor detects the position identifying member 131 located in the vane assembly 400 The dishwasher 1 can determine whether the vane assembly 400 has reached the second position P2.

Specifically, when the sub-position detecting sensor located at the second position P2 detects the position identifying member 131 attached to the vane assembly 400, the dishwasher 1 determines that the vane assembly 400 is in the second position P2), as shown in FIG.

When the vane assembly 400 reaches the second position P2 (example of 1320), the dishwasher 1 moves the vane assembly 400 in the first moving direction D1 (1330). Specifically, in order to move the vane assembly 400 in the first moving direction D1, the dishwasher 1 rotates the vane driving motor 520 in the first rotational direction (rotational direction for moving the vane assembly in the first moving direction) Respectively.

Then, the dishwasher 1 determines whether the vane assembly 400 has reached the first position Pl (1340).

The dishwasher 1 can determine whether the vane assembly 400 has reached the first position Pl in various ways.

For example, the dishwasher 1 determines whether the vane assembly 400 has reached the first position P1 according to whether the time when the vane driving motor 520 is rotated in the first rotation direction is equal to or longer than a first reference time can do.

In another example, when the vane drive motor 520 includes an encoder, the dishwasher 1 may be configured such that the product of the rotational displacement of the vane drive motor 520 in the first rotational direction and the drive pulley 530 is greater than a first reference distance It is possible to determine whether the vane assembly 400 has reached the first position P1.

As another example, when the dishwasher 1 includes the position detection unit 130, the dishwasher 1 may be configured such that the position detection sensor 132 positioned at the first position Pl is attached to the vane assembly 400 It is possible to determine whether the vane assembly 400 has reached the first position Pl depending on whether the position identification member 131 is detected.

When the vane assembly 400 reaches the first position Pl (example of 1340), the dishwasher 1 terminates the reciprocating movement of the vane assembly 400.

The dishwasher 1 can repeat such a vane moving operation 1300 to reciprocate the vane assembly 400 between the first position P1 and the second position P2.

In this way, the dishwasher 1 can wash the dishes in the entire tub 30 by reciprocating the vane assembly 400 between the foremost and the last rooms of the vane guide 510 as shown in FIG. 31 .

32 shows a vane movement control method according to another embodiment of the present invention.

A full cleaning operation 1400 will now be described with reference to Fig.

First, the dishwasher 1 moves the vane assembly 400 forward (1410) for a predetermined first reference time.

For example, if the first position is located at the rear end of the vane guide 510, the vane assembly 400 is moved forward for a first reference time such that the vane assembly 400 reaches the forefront of the vane guide 510 .

Specifically, the dishwasher 1 operates the vane driving motor 520 for a first reference time in a second rotational direction for moving the vane assembly 400 to the second position, thereby moving the vane assembly 400 to the second position Can be moved.

Here, the first reference time may be defined as the time taken for the vane assembly 400 to move from one end of the vane guide 510 to the other end. That is, the first reference time is calculated by dividing the length of the vane guide 510 by the moving speed of the vane assembly 400, and the calculated first reference time is previously stored in the storage unit 150, The reference time can be defined.

The dishwasher 1 moves the vane assembly 400 to the second position by driving the vane driving motor 520 in the second rotational direction for the first reference time, but is not limited thereto.

For example, the vane drive motor 520 may be provided with an encoder for sensing a rotational displacement, and an encoder may be used to move the vane assembly 400 by a distance between the first position and the second position, (520).

When the first reference time elapses, the dishwasher 1 moves the vane assembly 400 backward (1420).

For example, when the first position is located at the rear end of the vane guide 510, the vane assembly 400 is moved backward so that the vane assembly 400 returns to the first position.

More specifically, the dishwasher 1 operates the vane drive motor 520 in a first rotation direction in which the vane assembly 400 is moved to the first position, that is, in the opposite direction to that in the step 1410, 1 position.

Thereafter, the dishwasher 1 determines 1430 whether the vane assembly 400 has reached the first position. For example, if the first position is located at the rear end of the vane guide 510, it is determined whether the vane assembly 400 has reached the rear end of the vane guide 510.

Specifically, the dishwasher 1 can determine whether the position detecting sensor 132 has detected the magnetic field of the position identifying member 131. [

If the vane assembly 400 has not reached the first position (no in 1440), the vane assembly 400 continues to move the vane assembly 400 until it reaches the first position.

When the vane assembly 400 reaches the first position (1440 example), the dishwasher 1 stops the movement of the vane assembly 400 (1450). Specifically, the dishwasher 1 can stop the vane drive motor 520 from operating.

Thereafter, the dishwasher 1 determines whether the difference between the first reference time and the elapsed time of movement is equal to or greater than the tolerance (1450). Here, the movement elapsed time means a time when the vane assembly 400 moves from the second position to the first position.

If the difference between the first reference time and the elapsed time of movement is equal to or greater than the tolerance (example of 1450), the dishwasher 1 warns the user of malfunction of the dishwasher 1 (1460).

The difference between the first reference time and the elapsed time of movement is equal to or greater than the tolerance means that the time required for the vane assembly 400 to move to the first position is longer than the first reference time or shorter than the first reference time it means.

This also means that the movement of the vane assembly 400 is disturbed while the vane assembly 400 moves along the vane guide 510. Therefore, the dishwasher 1 informs the user that the operation of the linear washing unit 100 is abnormal through the control panel 90 or the like.

The dishwasher 1 determines whether the operation of the vane assembly 400 is abnormal by moving the vane assembly 400 to the first position while the vane assembly 400 reciprocates back and forth.

Next, the dishwasher 1 performs separate cleaning. Separate cleaning is a cleaning operation in which only the tableware housed in a specific portion of the inside of the tub 30 is cleaned by the user.

For example, the tub 30 may be divided into left and right portions to clean only the dishes stored in the left side of the tub 30, or only the dishes stored in the right side of the inside of the tub 30. In addition, it is also possible to divide the tub 30 back and forth, to clean only the dishes stored in the front of the tub 30, or to wash only the dishes stored in the rear of the tub 30.

Specifically, when the user inputs a left cleaning instruction through the left cleaning button 94a, the user controls the distribution valve assembly 200 to spray only the left side injection nozzle 330 of the dishwasher 1 nozzle assembly 110 can do.

In addition, when the user inputs the right cleaning command through the right cleaning button 94b, the dispensing valve assembly 200 is controlled so that only the right injection nozzle 111 among the nozzle assemblies 110 injects the washing water.

When the user inputs the front cleaning command through the front cleaning button 94c, the dishwasher 1 is operated by the vane driving assembly 500 so that the vane assembly 400 reciprocates in the front part of the inside of the tub 30 .

For example, when the first position is located at the rear end of the vane guide 510, the dishwasher 1 may move the vane assembly 400 to the above-described first reference time (the vane assembly moves from one end of the vane guide to the other end And moves toward the foremost side of the vane guide 510 for a predetermined period of time.

As a result, the vane assembly 400 is positioned at the forefront of the vane guide 510, and then the dishwasher 1 moves the vane assembly 400 rearward for a second reference time shorter than the first reference time The vane assembly 400 is moved backward in the front portion of the tub 30 by repeating the forward movement of the vane assembly 400 for the second reference time.

When the user inputs a backwash command through the backwash button 94d, the dishwasher 1 operates the vane drive assembly 500 such that the vane assembly 400 reciprocates inside the tub 30 .

For example, when the first position is located at the rear end of the vane guide 510, the dishwasher 1 moves the vane assembly 400 forward for a second reference time that is shorter than the first reference time, When the vane assembly 400 is repeatedly moved backward during the second reference time, the vane assembly 400 reciprocates in the rear portion of the tub 30.

Left Separated Wash, Right Separated Wash, Front Separated Wash, and Back Separated Wash are described in more detail below.

For the sake of understanding, it is assumed that the position detection sensor 132 is located at the rear end of the vane guide 510. [ That is, the first position is the last chamber of the vane guide 510.

However, the present invention is not limited thereto. For example, if the first position is located at any position of the vane guide 510, the vane assembly 400 may be moved to the rearmost chamber of the vane guide 510, When the first position is located at the foremost position of the vane guide 510, the following operation can be performed by changing only the forward and backward directions.

33 and 34 illustrate a vane movement control method according to a back washing operation according to an embodiment.

When the user presses the rear cleaning button 94d provided on the control panel 90 to input the rear cleaning command, the dishwasher 1 can perform the back cleaning operation 1500. [

33 and 34, the dishwasher 1 moves the vane assembly 400 in the second moving direction D2 (1510). More specifically, the dishwasher 1 can drive the vane driving motor 520 in the second rotational direction.

Thereafter, the dishwasher 1 determines 1520 whether the vane assembly 400 has reached the third position P3. Here, the third position P3 may be any position of the vane guide 510. [

The dishwasher 1 can judge in various ways whether the vane assembly 400 has reached the third position P3.

For example, the dishwasher 1 may determine whether the vane assembly 400 has reached the third position P3 according to whether the time when the vane driving motor is driven in the second rotational direction is the second reference time.

Here, the second reference time may be half of the first reference time. However, the present invention is not limited to this, and the second reference time may be longer or shorter than half of the first reference time.

In another example, the dishwasher 1 may be configured such that the vane assembly 400 is moved in the direction of the axis of the vane assembly 400 in accordance with whether the product of the rotational displacement of the vane drive motor 520 in the second rotational direction and the radius of the drive pulley 530 is equal to or greater than a second reference distance 3 position (P3) is reached.

As another example, when the position detecting section 130 includes the sub position detecting sensor located at the third position P3, it is determined whether the sub position detecting sensor detects the position identifying member 131 located in the vane assembly 400 The dishwasher 1 can determine whether the vane assembly 400 has reached the third position P3.

Here, the second reference distance may be half of the first reference distance. However, the present invention is not limited thereto, and the second reference distance may be longer or shorter than half of the first reference distance.

When the vane assembly 400 reaches the third position P3 (the example of 1520), the dishwasher 1 moves the vane assembly 400 in the first moving direction D1 (1530). Specifically, the dishwasher 1 can drive the vane driving motor 520 in the first rotational direction.

Then, the dishwasher 1 determines whether the vane assembly 400 has reached the first position Pl (1540).

The dishwasher 1 can determine whether the vane assembly 400 has reached the first position Pl in various ways.

For example, the dishwasher 1 determines whether the vane assembly 400 has reached the first position P1 according to whether the time when the vane driving motor 520 is rotated in the first rotation direction is equal to or longer than the second reference time can do.

In another example, when the vane drive motor 520 includes an encoder, the dishwasher 1 may be configured such that the product of the rotational displacement of the vane drive motor 520 in the first rotational direction and the drive pulley 530 is greater than a second reference distance It is possible to determine whether the vane assembly 400 has reached the first position P1.

As another example, when the dishwasher 1 includes the position detection unit 130, the dishwasher 1 may be configured such that the position detection sensor 132 positioned at the first position Pl is attached to the vane assembly 400 It is possible to determine whether the vane assembly 400 has reached the first position Pl depending on whether the position identification member 131 is detected.

As described above, the dishwasher 1 can wash the tableware housed in the rear of the tub 30 by reciprocating the vane assembly 400 from behind the vane guide 510, as shown in Fig.

35 shows a vane movement control method according to another embodiment of the back washing operation.

The back cleaning operation 1600 will be described with reference to Fig.

First, the dishwasher 1 moves the vane assembly 400 forward (1610) for a predetermined second reference time. Specifically, the dishwasher 1 may drive the vane drive motor 520 for a second reference time in a first rotational direction for moving the vane assembly 400 forward.

Here, the second reference time may be shorter than the first reference time described above. For example, the second reference time may be a time corresponding to half of the first reference time, in which case the vane assembly 400 is moved forward for a second reference time, 510).

However, the second reference time is not limited to half of the first reference time. It is also possible to set the second reference time longer than half of the first reference time, or to set the second reference time shorter than half of the first reference time have.

The dishwasher 1 then moves 1620 the vane assembly 400 backwards so that the vane assembly 400 reaches the rearmost or first position of the vane guide 510. Specifically, the dishwasher 1 may actuate the vane drive motor 520 in a direction opposite to the second rotational direction, that is, the step 1610, in which the vane assembly 400 is moved backward.

Thereafter, the dishwasher 1 determines 1630 whether the vane assembly 400 has reached the first position. Specifically, the dishwasher 1 determines whether or not the position detection sensor 132 has detected the magnetic field of the position identification member 131.

If the vane assembly 400 has not reached the first position (no at 1630), the vane assembly 400 continues to move the vane assembly 400 until it reaches the first position.

If the vane assembly 400 has reached the first position (example of 1630), the dishwasher 1 stops the movement of the vane assembly 400 (1640). Specifically, the operation of the vane drive motor 520 can be stopped.

Thereafter, the dishwasher 1 determines whether the difference between the second reference time and the elapsed time of movement is equal to or greater than the tolerance (1650). Here, the movement elapsed time means a time when the vane assembly 400 has moved to the first position.

If the difference between the second reference time and the elapsed time of movement is greater than or equal to the tolerance (example of 1650), the dishwasher 1 warns the user of the malfunction of the dishwasher 1 (1660).

The difference between the second reference time and the elapsed time of movement is equal to or greater than the tolerance means that the time required for the vane assembly 400 to move to the first position is longer than the second reference time or shorter than the first reference time it means.

This also means that the movement of the vane assembly 400 is disturbed while the vane assembly 400 moves along the vane guide 510. Therefore, the dishwasher 1 informs the user that the operation of the linear washing unit 100 is abnormal through the control panel 90 or the like.

The dishwasher 1 determines whether the operation of the vane assembly 400 is abnormal by moving the vane assembly 400 to the first position while the vane assembly 400 reciprocates rearward of the tub 30. [

36 and 37 illustrate a vane movement control method according to a front cleaning operation according to an embodiment.

Referring to Figs. 36 and 37, the dishwasher 1 moves the vane assembly 400 in the second moving direction D2 (1710). More specifically, the dishwasher 1 can drive the vane driving motor 520 in the second rotational direction.

Thereafter, the dishwasher 1 determines whether the vane assembly 400 has reached the second position P2 (1720).

The dishwasher 1 can judge in various ways whether the vane assembly 400 has reached the second position P2.

For example, the dishwasher 1 can determine whether the vane assembly 400 has reached the second position P2 according to whether the time when the vane driving motor is driven in the second rotational direction is the first reference time.

In another example, the dishwasher 1 may be configured such that the vane assembly 400 is moved in a direction in which the vane assembly 400 rotates in the second direction of rotation according to whether the product of the rotational displacement of the vane drive motor 520 in the second rotational direction and the radius of the drive pulley 530 is greater than a first reference distance 2 position (P2) is reached.

As another example, when the position detecting section 130 includes the sub-position detecting sensor located at the second position P2, it is determined whether the sub-position detecting sensor detects the position identifying member 131 located in the vane assembly 400 The dishwasher 1 can determine whether the vane assembly 400 has reached the second position P2.

When the vane assembly 400 reaches the second position P2 (example of 1720), the dishwasher 1 moves the vane assembly 400 in the first moving direction D1 (1730). Specifically, the dishwasher 1 can drive the vane driving motor 520 in the first rotational direction.

Then, the dishwasher 1 determines whether the vane assembly 400 has reached the fourth position P4 (1740).

The dishwasher 1 can determine whether the vane assembly 400 has reached the fourth position P4 in various ways.

When the vane assembly 400 reaches the fourth position P4 (example of 1740), the dishwasher 1 moves the vane assembly 400 in the second moving direction D2 (1750). More specifically, the dishwasher 1 can drive the vane driving motor 520 in the second rotational direction.

Then, the dishwasher 1 determines whether the vane assembly 400 has reached the second position P2 (1760).

The dishwasher 1 can judge in various ways whether the vane assembly 400 has reached the second position P2.

For example, the dishwasher 1 may determine whether the vane assembly 400 has reached the second position P2 according to whether the time when the vane driving motor is driven in the second rotational direction is the third reference time.

Alternatively, the dishwasher 1 may be configured such that the vane assembly 400 is moved in the direction of the axis of the vane assembly 400, depending on whether the product of the rotational displacement of the vane drive motor 520 in the second rotational direction and the radius of the drive pulley 530 is equal to or greater than a third reference distance 2 position (P2) is reached.

As another example, when the position detecting section 130 includes the sub-position detecting sensor located at the second position P2, it is determined whether the sub-position detecting sensor detects the position identifying member 131 located in the vane assembly 400 The dishwasher 1 can determine whether the vane assembly 400 has reached the second position P2.

When the vane assembly 400 reaches the second position P2 (example of 1760), the dishwasher 1 determines 1770 whether the forward cleaning time has elapsed. Here, the front cleaning time may be a time set by the user or a pre-stored time for washing the tableware housed in front of the tub 30.

If the forward cleaning time has not elapsed (No in 1770), the dishwasher 1 reciprocates the vane assembly 400 between the second position P2 and the fourth position P4.

If the washing time has not elapsed (YES in 1770), the dishwasher 1 moves the vane assembly 400 in the first moving direction D1 (1780). Specifically, the dishwasher 1 can drive the vane driving motor 520 in the first rotational direction.

Then, the dishwasher 1 determines whether the vane assembly 400 has reached the first position Pl (1790).

38 shows a vane movement control method according to another embodiment of the front cleaning operation.

The front cleaning operation 1800 will be described with reference to FIG.

First, the dishwasher 1 moves the vane assembly 400 forward (1810) for a predetermined first reference time so that the vane assembly 400 reaches the foremost position of the vane guide 510. Here, the first reference time may be defined as a time at which the vane assembly 400 moves from the rearmost position to the foremost position of the vane guide 510.

Thereafter, the dishwasher 1 moves the vane assembly 400 backward (1820) for a second predetermined reference time such that the vane assembly 400 reaches the center of the vane guide 510.

Here, the second reference time may be shorter than the first reference time described above. For example, the second reference time may be a time corresponding to half of the first reference time. Of course, the present invention is not limited to a half of the first reference time, but may be set longer than half of the first reference time or shorter than half of the first reference time.

The dishwasher 1 then moves 1830 the vane assembly 400 forward for a second reference time such that the vane assembly 400 reaches the forefront of the vane guide 510.

Thereafter, the dishwasher 1 determines whether the time for which the vane assembly 400 has been reciprocated forward is equal to or greater than a predetermined reference reciprocation time (1840). However, the present invention is not limited thereto. That is, the dishwasher 1 may determine whether the vane assembly 400 has been reciprocated forward by a predetermined number of times or more.

The dishwasher 1 continues the reciprocating movement of the vane assembly 400 unless the time when the vane assembly 400 has been reciprocated forward is equal to or longer than the predetermined reference reciprocation time (NO in 1840).

Of course, the dishwasher 1 may continue reciprocating movement of the vane assembly 400 if the number of reciprocations of the vane assembly 400 forward is not more than the reference number of reciprocations.

The dishwasher 1 stops the forward reciprocating movement of the vane assembly 400 and the vane assembly 400 is moved backward by a predetermined amount of time The vane assembly 400 is moved back 915 to reach the first position.

Of course, if the number of forward reciprocating movements of the vane assembly 400 is equal to or greater than the reference number of reciprocations, the dishwasher 1 stops the forward reciprocating movement of the vane assembly 400 and moves the vane assembly 400 to the first position The assembly 400 may be moved backward.

The subsequent steps 1850 to 1890 are the same as steps 1630 to 1660 shown in FIG. 35, and therefore, the description thereof will be omitted.

Thereafter, the dishwasher 1 moves the vane assembly 400 in the second direction for a first reference time, and repeats moving the vane assembly 400 again in the first direction for a first reference time.

Thus, the dishwasher 1 can wash the dishes stored on the right side of the tub 30. In other words, the cleaning range of the linear washing unit 100 becomes the right half of the tub 30 as shown in Fig.

In the above description, the dishwasher 1 cleans the predetermined washing area according to the user's selection. For example, the dishwasher 1 can wash the front, rear, left and right sides of the tub 30 separately.

Hereinafter, the dishwasher 1 will be described in which the washing area is inputted from the user and the washing area is cleaned.

FIG. 41 shows a divided washing operation according to an embodiment, FIG. 42 shows a washing zone input method according to an embodiment, and FIG. 43 shows a washing zone inputting method according to another embodiment.

Referring to Figs. 41 to 43, a divided cleaning operation 1900 for receiving a cleaning area from a user and cleaning the received cleaning area will be described.

First, the dishwasher 1 determines whether the user inputs a washing zone (1910).

The user can input the washing zone into the dishwasher 1 in various ways.

The user U can input the wash zone by touching or dragging the split wash screen 700 of the control panel 90. [

For example, the dishwasher 1 may display a nozzle assembly image 730, a vane assembly image 740, and a vane guide image 750 on the divided cleaning screen 700.

When the user U touches the divided washing screen 700, the dishwasher 1 calculates the coordinates touched by the user U and displays the vane assembly image 740 in the calculated coordinates as shown in (a ) And 43 (a).

Also, the dishwasher 1 determines whether the position touched by the user U is on the left or right side of the vane guide image 750.

Thereafter, the user U can input the washing zone by moving the touched portion while keeping the contact with the divided washing screen 700.

When the touch coordinates are moved, the dishwasher 1 moves the vane assembly image 740 along the position touched by the user U. That is, the dishwasher 1 calculates coordinates touched by the user U at predetermined time intervals, and displays the vane assembly image 740 in the calculated coordinates as shown in FIGS. 42 (b) and 43 (a) And is displayed again as shown.

Also, while the vane assembly image 740 is moving, the dishwasher 1 displays the moving part of the vane assembly image 740 so as to be distinguished from other parts.

As will be described below, the marked areas are marked as wash zones.

At this time, if the first touched position is the left side of the vane guide image 750 and the position where the touch is moved is also the left side of the vane guide image 750, the dishwasher 1, as shown in FIG. 42 (b) Only the left part of the vane guide image 750 is displayed so as to be distinguished from the part where the assembly image 740 has moved.

When the left part of the vane assembly image 750 is displayed to be distinguished from other parts of the divided washing screen 700 among the locus of the vane assembly image 750 moved, And becomes the left portion of the partial center vane guide image 750.

If the first touched position is the left side of the vane guide image 750 and the touched position is the right side of the vane guide image 750, And displays all of the moved parts of the assembly image 740 so as to be distinguished.

 In this manner, when all of the locus of movement of the vane assembly image 750 is displayed to be distinguished from other parts of the divided cleaning screen 700, the cleaning area becomes all of the moved part of the vane assembly image 740.

When the user U stops touching, the dishwasher 1 stops moving the vane assembly image 740.

Further, the dishwasher 1 displays the washing zone input by the user U. At this time, the cleaning zone is a portion marked differently from the other portions while the vane guide image 750 is moving.

Hereinafter, a position on the vane guide 510 corresponding to the position where the user U starts the touch is referred to as a fifth position P5, and a position corresponding to the position where the touch by the user U is ended And the position on the vane guide 510 is referred to as a sixth position P6.

Although the method of inputting the washing zone through the divided washing screen 700 provided in the control panel 90 has been described above, the method of inputting the washing zone is not limited thereto.

For example, the user can set the washing zone by storing the dishes in the baskets 22a and 22b, then marking the places where the dishes are housed in the baskets 22a and 22b, or attaching tags to the places where the dishes are stored .

The dishwasher 1 can calculate the washing area based on the marked portion and the tag-attached portion among the baskets 22a and 22b.

When the washing zone is input (YES in step 1910), the dishwasher 1 selects the spray nozzle for spraying wash water according to the input washing zone (1920).

For example, when the washing area is displayed only on the left side of the vane guide image 750 in the divided washing screen 700, the dishwasher 1 supplies washing water to the left side injection nozzle 330 and supplies the washing water to the right side injection nozzle 340 And controls the dispensing valve assembly 200 such that no wash water is supplied.

When the washing area is displayed on the right side of the vane guide image 750 in the divided washing screen 700, washing water is not supplied to the left side injection nozzle 330 and the washing water is supplied to the right side injection nozzle 340 And controls the dispense valve assembly 200 so that wash water is supplied.

The dishwasher 1 is provided with the dispensing valve assembly 200 so that the washing water is supplied to both the left side injection nozzle 330 and the right side injection nozzle 340. In the case where the cleaning area is displayed on both sides of the vane guide image 750, .

Then, the dishwasher 1 calculates the moving interval of the vane assembly 400 according to the input washing zone (1930).

For example, in the dishwasher 1, the dishwasher 1 is moved to the position of the fifth position P5 on the vane guide 510 and the position of the vane guide 510 on the basis of the washing zone input through the divided washing screen 700 510). ≪ / RTI >

Specifically, the dishwasher 1 uses the ratio between the length of the vane guide 510 and the length of the vane guide image 750 to determine whether the user touches the divided washing screen 700 The coordinates of the position P5 may be calculated and the coordinates of the sixth position P6 may be calculated based on the position at which the user has finished touching the divided washing screen 700. [

The dishwasher 1 also calculates the distance between the first position P1 and the fifth position P5 and the distance between the first position P1 and the sixth position P6 . The dishwasher 1 calculates the distance between the first position P1 and the fifth position P5 based on the coordinates of the fifth position P5 and the coordinates of the sixth position P6, It is possible to calculate the distance between the sixth position P6.

The dishwasher 1 is installed in the vane assembly 400 on the basis of the moving speed of the vane assembly 400 and the distance between the first position P1 and the fifth position P5 in accordance with the rotational speed of the vane driving motor 520, To the fifth position P5 from the first position P1 to the fifth position P5. Also, the dishwasher 1 can calculate the movement time necessary for the vane assembly 400 to move from the first position P1 to the fifth position P5 in the same manner.

The dishwasher 1 is also provided with a movement time interval between the fifth position P5 and the sixth position P6 or between the fifth position P5 and the sixth position P6, .

Then, the dishwasher 1 drives the dispense valve assembly 200 and the vane drive assembly 500 (1940) so that cleaning is performed for the cleaning area.

Specifically, the dishwasher 1 drives the dispensing valve assembly 200 so that the left side injection nozzle 330 or the right side injection nozzle 340 injects the washing water in accordance with the washing area. In addition, the dishwasher 1 drives the vane drive assembly 500 to move the vane assembly 400 along the wash zone.

The dishwasher 1 can judge in various ways whether the vane assembly 400 has reached the sixth position P6.

For example, the dishwasher 1 may be configured such that the time when the vane driving motor 520 is rotated in the second rotational direction is required for the vane assembly 400 to move from the fifth position P5 to the sixth position P6 It is possible to determine whether the vane assembly 400 has reached the sixth position P6.

In another example, when the vane drive motor 520 includes an encoder, the dishwasher 1 may be configured such that the product of the rotational displacement of the vane drive motor 520 in the first rotational direction and the drive pulley 530, P5) and the sixth position (P6), whether the vane assembly 400 has reached the sixth position P6 or not.

When the vane assembly 400 reaches the sixth position P6 (YES in 1946), the dishwasher 1 determines 1947 whether the divided cleaning time has elapsed. Here, the divided washing time may be a time set by the user or a pre-stored time for washing the tableware housed in front of the tub 30.

If the divided washing time has not elapsed (NO in 1947), the dishwasher 1 reciprocates the vane assembly 400 between the fifth position P5 and the sixth position P6.

If the divided washing time has not elapsed (YES in 1947), the dishwasher 1 moves the vane assembly 400 in the first moving direction D1 (1948). Specifically, the dishwasher 1 can drive the vane driving motor 520 in the first rotational direction.

Then, the dishwasher 1 judges whether the vane assembly 400 has reached the first position Pl (1949).

The dishwasher 1 can determine whether the vane assembly 400 has reached the first position Pl in various ways.

For example, the dishwasher 1 determines whether the time when the vane driving motor is driven in the first rotational direction is longer than the time required for the vane assembly 400 to move from the sixth position P6 to the first position P1 To determine whether the vane assembly 400 has reached the first position P1.

As another example, the dishwasher 1 may be configured such that the product of the rotational displacement of the vane drive motor 520 in the first rotational direction and the radius of the drive pulley 530 is between the first position P1 and the sixth position P2 It is possible to determine whether the vane assembly 400 has reached the first position P1 according to whether the distance is equal to or greater than the distance.

As another example, when the dishwasher 1 includes the position detection unit 130, the dishwasher 1 may be configured such that the position detection sensor 132 positioned at the first position Pl is attached to the vane assembly 400 It is possible to determine whether the vane assembly 400 has reached the first position Pl depending on whether the position identification member 131 is detected.

In this way, the dishwasher 1 can receive the washing zone from the user for the divided washing, and the left side injection nozzle 330 or the right side injection nozzle 340 can inject the washing water according to the washing zone, Control the assembly 200, and control the vane drive assembly 500 such that the vane assembly 400 reciprocates.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein; It will be understood that various modifications may be made without departing from the spirit and scope of the invention.
