The cleaning apparatus 100 sucks the stored water W on the bottom surface, filters the foreign substances contained in the stored stored water W, and discharges the filtered stored water W to the outside. The cleaning apparatus 100 is driven through a force (referred to as a water-jet pressure) for discharging the stored water W to the outside.

The cleaning apparatus 100 can operate a plurality of discharge pipes 153a, 153b, 153c and 153d (see FIG. 3) while being exposed to the air after discharging a part of the stored water W in the water tank 10 , Or the water (W) stored in the water tank (10), and then submerged in water. It may be better to keep the stored water W in the water tank 10 intact and to operate while submerged in water in order to increase the efficiency of the cleaning apparatus 100. [

FIG. 2 is a perspective view showing the appearance of the cleaning apparatus according to the present embodiment, and FIG. 3 is a perspective view showing the inside of the cleaning apparatus according to the present embodiment.

Referring to FIG. 2, the cleaning apparatus 100 includes a body portion 103 including a case 101 and a base 102. The body portion 103 forms an outer shape of the cleaning apparatus 100, and the interior thereof can be sealed so as to maintain the waterproofness. When the case 101 is opened, the pump 110, the control unit 120, the sensor unit 130, the battery 140, the driving unit 150, and the steering unit 160 are installed on the base 102. The shapes and arrangements of the elements disposed in the base 102 are merely examples, and can be modified in various forms.

A plurality of wheels 151 for receiving a driving force by the driving unit 150 are disposed below the base 102. The wheel 151 can use a passive ball joint mechanism.

The pump 110 sucks the stored water W from the bottom of the water tank through an inlet (not shown) disposed at the lower end of the base 102. A filter (not shown) is provided in the pipe connecting the pump 110 and the suction port (not shown), and the filter (not shown) filters sediment and other residues from the stored water W.

The control unit 120 controls the overall operation of the cleaning apparatus 100. [ The control unit 120 monitors the voltage level of the battery 140, changes the path of the cleaning device 100 through the control of the driving unit 150, and sends and receives operation signals to / from the external device wirelessly. The control unit 120 includes a wireless interface unit for wirelessly communicating with an external device. The wireless interface may use a well-known technology such as a radio frequency (RF) device, a wireless LAN, a Bluetooth, and an infrared sensor.

The sensor unit 130 may include an acceleration sensor module of the cleaning apparatus 100. As the acceleration sensor module, a gyro sensor can be used. The acceleration sensor module can sense the dynamic force of the cleaning device 100, such as acceleration, vibration, shock, and the like. The acceleration sensor module can sense that the cleaning apparatus 100 collides with an obstacle inside the water tank or an inner wall of the water tank while the cleaning apparatus 100 is running. The sensor unit 130 can significantly reduce the number of components of the external component and efficiently operate the cleaning device 100.

The battery 140 supplies power to the pump 110. The battery 140 may be a well-known lithium-polymer battery, and the configuration and the form of the battery 140 are not limited.

And a buoyancy regulator (not shown) for diving may be additionally disposed on the base 102 in the base 102. Initially, the buoyancy regulator is filled with water for diving, and when the voltage of the battery 140 drops below a certain level, the buoyancy regulator is drained and the cleaning device 100 rises above the water surface.

On the other hand, the driving unit 150 provides the driving force to the cleaning device 100. The driving unit 150 includes an inlet pipe 152 connected to the pump 110, first, second, third, and fourth discharge pipes 153a, 153b, and 153c connected to the inlet pipe 152 and connected to the steering unit 160, 153c, and 153d.

FIG. 4 is a perspective view showing a part of the steering unit of the cleaning apparatus according to the present embodiment, and FIG. 5 is a plan view showing a steering operation of the steering unit of the cleaning apparatus according to the present embodiment.

4 and 5, the steering portion 160 includes a steering body 161, a rotating cylinder 162, and a support plate 163. [

The steering body 161 is formed with a hollow portion 161a communicating with the inflow pipe 152. The first, second, third, and fourth outlets 153a ', 153b', 153c, and 153d, which are connected to the hollows 161a and connected to the first, second, third, and fourth discharge pipes 153a, 153b, 153c, 153b ', 153c', and 153d 'are formed.

The rotating cylinder 162 is inserted into the hollow 161a. The side wall of the rotary cylinder 162 is formed with a communication port 162a communicating with the discharge port of at least one of the first, second, third and fourth discharge ports 153a ', 153b', 153c ', and 153d'. In the accompanying drawings, the communication port 162a is shown as communicating with two outlets, but it should not be understood that the number of outlets is limited.

As the rotary cylinder 162 is rotated, the cleaning device 100 can be moved in the direction opposite to the discharge pipe communicating with the first, second, third and fourth discharge ports 153a ', 153b', 153c ', and 153d' have.

In this way, the water sucked by the pump 110 is discharged to the outside of the cleaning apparatus 100. The pressure of the water to be discharged is simply dependent on the suction force of the pump 110 and no separate discharge means is required. At this time, in order to increase the pressure of water discharged through the first, second, third and fourth discharge pipes 153a, 153b, 153c and 153d, the first, second, third and fourth discharge pipes 153a, 153b, 153c and 153d The internal area may be smaller than the internal area of the inlet pipe 152. The internal area is the area through which water passes.

6 is a plan view showing the running operation of the cleaning apparatus according to the present embodiment.

Referring to FIG. 6, the water sucked by the pump 110 flows into the steering unit 160 through the inlet pipe 152. The water flowing into the steering portion 160 flows into the hollow portion 161a of the steering body 161. [ At this time, the rotation cylinder 162 controls the position of the communication port 162a in accordance with the traveling direction of the cleaning device 100. [

For example, when the rotary cylinder 162 is positioned such that the communication port 162a communicates with the first and second discharge ports 153a 'and 153b', the cleaning device 100 is moved in the first direction shown in FIG. 5 And the rotary cylinder 162 is positioned so that the communication port 162a communicates with the third and fourth discharge ports 153c 'and 153d', the cleaning apparatus 100 can be moved in the second direction.

According to the present invention, a driving force is obtained by a water jet spraying method using a suction force provided by the pump 110, without using a separate power source for driving the cleaning apparatus 100. Since the pump 110 used for underwater cleaning maintains a large amount of flow and high discharge pressure, it can be utilized as moving energy of the cleaning apparatus 100. Because of the characteristics of cleaning the bottom of the tank, there is almost no sudden change of direction, simply moving forward and moving the entire tank bottom.

If a separate power source is required to drive the cleaning device as in the conventional cleaning device, the internal battery must supply power to the driving wheel in addition to the pump. Therefore, the battery volume becomes large to operate wirelessly, There is a limit to providing a cleaning device that operates wirelessly. In the present invention, since the driving force is obtained from the water jet injection method and the internal battery can be used only for supplying power only to the pump, the weight of the cleaning device can be reduced. Therefore, the wireless interface can be used because the battery alone can provide sufficient operating time.

When the cleaning device 100 travels in the water tank and collides with the obstacle or the inner wall of the water tank, the sensor unit 130 senses acceleration, vibration, shock, and the like of the cleaning device 100. When acceleration, vibration, shock, or the like is sensed in the cleaning device 100, the rotating cylinder 162 of the steering unit 160 is rotated to change the traveling direction of the obstacle or the cleaning device 100 toward the inner wall of the water tank .

Therefore, according to the present invention, it is possible to smoothly travel the cleaning apparatus 100 without adding an element such as a bumper, a position sensor or the like around the body 103.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention. You will understand. Therefore, it is intended that the present invention covers all embodiments falling within the scope of the following claims, rather than being limited to the above-described embodiments.
