In the washing process, the body moves inside the accommodation space by the rotation of the impeller 12. Therefore, when the suction port or the discharge port is provided in the protrusion, the suction port or the discharge port is moved in the accommodation space R, There is a fear of clogging by the bottom surface of laundry R or laundry. If the suction port or the discharge port is clogged, it is difficult to circulate the washing water in the receiving space through the drain pipe at the beginning of washing, and it may be difficult to drain the washing water to the outside of the receiving space through the drain pipe at the end of washing.

Furthermore, the washing robot 1 may further include a sensing unit 15 provided inside the body 11 to collect data necessary for washing, as shown in FIG.

In this case, the water level sensor 153 may include a flow unit 1531 for flowing in the washing water inlet pipe 151 and a sensing unit 1533 for sensing the movement of the flow unit. have.

The flow unit 1531 may be provided to flow through the washing water inflow pipe 151 by buoyancy. When the washing water is supplied to the accommodation space R, the washing water will flow into the washing water inflow pipe through the inlet 1513, and the flow means provided in the washing water inflow pipe can wash water, Lt; RTI ID = 0.0 > height. ≪ / RTI >

In this case, the sensing means 1533 may include a reed switch or a Hall effect sensor for sensing the movement of the flow means, and may be electrically connected to a control unit 16 (see FIG. 6) It is preferable to be connected.

The sensing means 1533 may be disposed at the same level as the water level required for washing the laundry stored in the storage space R of the washing water inflow pipe 151. That is, if the water level at which half of the washing robot 1 is locked is a proper water level required for washing, the sensing means will be provided at a position corresponding to the radius of the body 11 from the inlet 1513.

The control unit 16 transmits a signal to the water supply unit controller 36 (see FIG. 6) through the communication unit 17 (see FIG. 5) when it is determined that the wash water having an appropriate level is supplied to the accommodation space R through the sensing means So that the water supply valve 331 (see FIG. 9) of the water supply unit 3 is closed.

The contamination detection sensor 155 is a means for detecting the time when the washing robot 1 needs to be replaced during the washing operation and may detect various types of contamination of the washing water stored in the receiving space R A sensor may be provided. In the following, a contamination detection sensor provided as a light emitting means and a light receiving means will be described as an example.

The contamination detection sensor provided as the light emitting means 1551 and the light receiving means 1553 is provided outside the washing water inflow pipe 151 so that the light receiving means can sense the intensity of the light emitted from the light emitting means Do. That is, the light emitting means and the light receiving means may be provided so as to face each other on the outer peripheral surface of the washing water inflow pipe. In this case, the light emitting means and the light receiving means are preferably connected to the controller 16 of the washing robot 1.

The light receiving means 1553 is means for sensing the intensity of light emitted from the light emitting means 1551. Accordingly, if the contamination of the washing water stored in the accommodation space R is severe, the washing water will contain a large amount of contaminants, and if the washing water contains a large amount of contaminants, The controller 16 can determine the washing water replacement time according to the intensity of the light sensed by the light receiving unit.

If it is determined that the washing water stored in the receiving space R needs to be replaced, the controller 16 discharges the washing water in the receiving space R to the outside of the receiving space through the drainage unit 14, The control unit 36 of the water supply unit 3 transmits a signal to the water supply unit communication unit 32 via the water supply unit communication unit 17 and opens the water supply valve 331 when the water supply unit communication unit 32 receives the wash water replacement signal So that the washing water is supplied to the accommodation space R.

Hereinafter, the entanglement detection means 157 will be described with reference to FIG.

The laundry robot 1 is rotated by the impeller between the laundry and the protruding portion 111 while the body 11 moves inside the accommodation space by the water flow inside the accommodation space R generated by the impellers 121 and 123, . Therefore, when the laundry is twisted with the impellers 121 and 123 of the washing robot 1, it is difficult to expect washing through the washing robot. Therefore, the tangle detection means 157 detects the impellers 121 and 123 of the washing robot 1 It may be provided to determine whether or not the laundry contained in the accommodation space R is clogged.

The entanglement detecting means 157 may be provided as means for detecting a change in rotation speed or rotation speed of the first motor 131 and the second motor 133 or may detect a change in current supplied to the respective motors Or may be provided as a means.

First, for example, an entanglement detecting means in the form of an encoder capable of detecting a change in the number of revolutions of a motor is exemplified. The entanglement detecting means provided in the form of an encoder is provided on the back surface of the first motor and the second motor, A plurality of slots 1573 provided through the circular plate and disposed along the circumference of the circular plate 1571 and a plurality of slots 1573 disposed in the circular plate 1571, 1575 and a light receiving means 1577. The light emitting means 1575 and the light receiving means 1577 are electrically connected to the control portion 16 through a PCB.

In this case, the control unit 16 can determine whether or not blotting has occurred based on a period of time during which the light receiving unit 1577 senses the light emitted from the light emitting unit. That is, when there is no entangling, the light receiving means will receive the light emitted from the light emitting means at a constant period, but if the trapping occurs, the period of receiving the light emitted from the light emitting means will become longer, The user can judge whether or not the user 16 is entangled.

On the other hand, in the case where the bending is detected through the change of the current supplied to the motor, the control unit 16 can serve as a tangling detection means. If the entangling occurs, the load of the first motor and the second motor increases, and the amount of current supplied to each motor will also increase. Therefore, if the control unit 16 periodically measures the amount of current supplied to the first motor and the second motor, it is possible to determine whether or not a blister occurs.

When the entanglement detection means 157 detects the entanglement, the controller 16 of the washing robot controls the motors 131 and 133 so that the impeller rotates in a direction opposite to the rotating direction before the entangling of the impellers 121 and 123, So that it is possible to eliminate the self-trapping.

The control unit 16 controls the operation of the washing robot 1 in the body 11 of the washing robot 1 or the notification unit (not shown) provided in the water supply unit 3, You may also notice tangles.

When the washing is completed, the washing robot (1) should discharge the washing water in the receiving space (R) to the outside of the receiving space through the drainage part (14). It is preferable that the suction port 1411 of the drain pipe 141 faces the bottom surface of the receiving space in order to discharge the washing water as much as possible to the outside of the receiving space. The position sensor (not shown) Is a means for providing information for controlling the attitude of the robot (1) so that the suction port (1411) can be directed to the bottom surface of the accommodation space (R).

Various types of sensors may be used as the position sensing sensor as long as the position of the inlet 1411 can be determined. Hereinafter, an accelerometer will be described as an example.

A position sensor 159 (see FIG. 5) provided as an acceleration sensor is provided on the PCB to provide information on the degree of inclination of the body 11 and the position of the drain pipe 141 to the control unit 16 . Therefore, the controller 16 can determine the angle θ (refer to FIG. 9 (b)) formed by the bottom surface of the receiving space R and the drain pipe 141 at a specific point of time through the position sensor.

The control unit 16 controls the position of the laundry robot in such a manner that the angle θ between the drain pipe 141 and the bottom surface of the accommodation space R is between 60 degrees and 70 degrees, . Since the laundry robot 1 is located inside the accommodation space R, when the drain pipe has an angle of 60 to 70 degrees with respect to the bottom surface of the accommodation space, it is easy to discharge the wash water in the accommodation space to the outside of the accommodation space (See Fig. 9 (d)).

Further, it is necessary for the control unit 16 to check whether the wash water in the accommodation space is discharged through the water level sensor. If the suction port 1411 of the drain pipe is clogged by laundry or foreign matter, the drainage pipe may not be discharged even if the drain pipe is properly positioned. Therefore, the control unit observes whether the water level is reduced through the water level sensor, If the position of the laundry robot is moved through the impeller, it is possible to solve the above-mentioned problem.

The washing robot 1 may further include a communication unit 17 capable of wireless communication with a water supply unit communication unit 32 provided in a water supply unit 3 to be described later.

As described above, the portable washing machine of the present invention can be configured only by the washing robot 1, but if it includes the water supply unit 3, it is possible to control the drainage and water supply of the washing water inside the accommodation space R by itself do.

As shown in FIG. 1, it is preferable that the water supply unit 3 includes a water supply connection 33 in the water supply unit body 31 so as to be detachable from the water supply part F to which wash water is supplied. The water supply connection port 33 is provided with a water supply valve 331 such as a solenoid valve capable of selectively opening and closing the water supply unit F. The water supply valve 331 is selectively connected to the water supply unit control unit 36 by a water supply unit control unit 36, The part can be opened.

The water supply unit 3 may further include an input unit 34 for inputting a control command such as a washing course to the washing robot 1. [ The movement of the laundry robot 1 in the accommodation space R may vary depending on the rotational speed and direction of the impeller and the washing force by the washing robot may vary depending on the water supply / Can be defined as an operation pattern of the washing robot 1 divided by the movement of the body 11 located in the receiving space and the water supply and drainage periods of the washing water.

The water supply unit 3 may include a water supply unit communication unit 32 capable of wirelessly communicating with the communication unit 17 of the laundry robot 1.

Therefore, the user can charge the battery of the washing robot only by inserting the washing water inflow pipe of the washing robot into the insertion part 53. [

FIG. 9 is a view illustrating an operation process of the portable washing machine of the present invention. Referring to FIG. 9, a washing process through the portable washing machine of the present invention will be described below.

First, the user places the accommodating space R containing the laundry L in such a manner that the washing water can be introduced from the water supplying part F. At this time, the user fixes the water supply unit 3 to the water supply part F and inserts the laundry robot 1 into the accommodation space R in which the laundry L is stored (Fig. 9 (a)). At this time, if the laundry is detergent, the detergent will be supplied to the containing space R together with the laundry.

The user inputs the selection of the washing course and the washing start signal through the input unit 34 of the water supply unit 3. [ When the washing start signal is inputted, the water supply unit control unit 36 opens the water supply valve 331 to supply the washing water provided in the water supply unit F to the accommodation space R, (Fig. 9 (b)).

The water supply unit 3 supplies the washing water until a signal indicating that the washing water has been supplied from the communication unit 17 of the washing robot 1 to a predetermined water level is provided. It is determined whether or not the wash water has been supplied to a predetermined water level.

The washing robot 1 performs a drying process while the washing water is supplied into the receiving space R. The drying cycle is performed by circulating the washing water in the receiving space through the drain pipe 141 and the drain pump, And the detergent is dissolved in the washing water. The washing robot may be controlled to move inside the receiving space simultaneously with the washing water circulation for more effective covering.

On the other hand, if it is determined that an adequate amount of wash water has been supplied to the accommodation space R, the water supply unit 3 stops the supply of the wash water through the water supply valve 331, and the washing robot 1 performs full- (Fig. 9 (c)).

The laundry is washed by the water flow generated due to the rotation of the impeller of the washing robot 1, the friction force of the laundry, the chemical action of the detergent, and the friction between the washing water and the protrusion 111 provided in the washing robot. Since the impeller may be entangled in the laundry during the washing process, the controller 16 of the washing robot observes whether the impeller is clogged with the laundry through the entanglement detecting sensor, and when the impeller is tangled, the speaker 37 ) Or the display unit 35 to notify the user of the tangling.

Meanwhile, it is preferable that the laundry robot is provided with a plurality of laundry courses so as to realize movement classified according to the type of laundry or the degree of contamination of the laundry. In this case, the washing course may be defined as a combination of the rotational speed of the impeller, the rotational direction of the impeller, the number of times of water supply and drainage, the water supply and drainage period, and the washing time.

When the set washing process is completed, the washing robot 1 discharges the washing water in the containing space R to the outside of the receiving space (FIG. 9 (d)).

When the angle of the drain pipe is perpendicular to the bottom surface, the washing water can not be discharged to the outside of the accommodation space. Therefore, in the discharge process, the drain pipe 141 provided in the washing robot 1 has an angle of 60 to 70 degrees Is preferably controlled to have an angle? The control unit 16 of the washing robot determines whether the drain pipe 141 is positioned at a predetermined angle with respect to the floor surface through the position sensor 159. If the drain pipe 141 is positioned at a predetermined angle, The washing water in the space is discharged to the outside of the accommodation space.
