Left and right wheels to be obtained, left and right running motors that can rotate each wheel respectively, a detector that is installed only on the front side and can detect the side of the pool, and a left and right running motor that can change direction alternately to the left and right depending on the detector. The pool consists of a controller that can control the motor, a cable that can supply power from the power source outside the pool to the submersible pump and the left and right running motors, and a remote controller that can remotely control the left and right running motors. There are characteristics.

(Function) The pool cleaner is submerged so that its wheels abut on the bottom of the pool.

When the submersible pump is activated, the sediment on the bottom of the pool is sucked and cleaned.

When the left and right running motors are activated, the left and right wheels rotate and run on the bottom of the pool under their own power.

When it reaches the side of the pool, a detector detects this and a controller controls the driving motor to change direction.

The submersible pump and left and right running motors are supplied with power via cables from a power source outside the pool, but the pool cleaner changes direction alternately to the left and right each time it reaches the side of the pool, depending on the detector and controller. , the cable will not get twisted.

By operating the remote controller, the left and right running motors can be remotely controlled, and the pool cleaner can be moved in any direction.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a plan view showing a pool cleaner according to an embodiment of the present invention. Figure 2 is a side view. Figure 3 is a front view. Figure 4 is an electrical circuit diagram. FIG. 5 is a schematic plan view for explaining the running operation.

The main parts of the pool cleaner 1 include a submersible pump 2, wheels 3, a running motor 4, a detector 5, a controller 6, a cable 7, and a remote controller 8.

The submersible pump 2 is capable of sucking sediment on the bottom of the pool.

In this example, a system in which a pump 10 and a motor 11 for rotating the pump are integrated is used.

The pump 10 includes a suction port 12 that opens close to the bottom surface 101 of the pool 100 and a discharge port 13 that opens upward. A filter 14 is connected.

The wheels 3 are connected to the submersible pump 2 on the bottom surface 101 of the pool.
It can be moved from side to side.

In this example, left and right casters 15 and left and right drive wheels 16 are used.

The casters 15 are provided on both sides of a frame 18 fixed to the lower part of the pump casing 17 of the submersible pump 2.

The drive wheel 16 is a hollow frame 20 that is sealed and fixed to the rear of the motor casing 19 of the submersible pump 2.
on both sides.

The running motors 4 are left and right motors that can rotate each wheel 3, respectively.

In this example, a geared motor consisting of a motor 21 and a speed reducer 22 is used.

Each geared motor is provided on both sides inside the hollow frame 20, each output shaft is sealed and protrudes outward, and a drive wheel 16 is fixed to the same portion.

The detector 5 is capable of detecting the side surface 102 of the pool.

In this example, a movable bumper 23 and a limit switch 24 operated by the movable bumper 23 are used.

The movable bumper 23 includes left and right guide rods 25 that can move back and forth with respect to the frame 18, a bumper 26 that connects the front parts of these rods, a left and right spring 27 that constantly biases the guide rod 25 forward, and a guide rod 25 that is movable back and forth with respect to the frame 18. Rod 2
5, and an operating rod 29 which extends from the middle of the connecting rod 28 into the hollow frame 20 and is sealed.

The limit switch 24 is provided inside the hollow frame 20 and is operated by retracting the operating rod 29.

The controller 6 is capable of controlling the left and right running motors 4 to alternately change direction to the left and right based on the detector 5.

In this example, timers T1 to T5, auxiliary relay
1 to X3, transformer Tr, diode D, ratchet relay RR, regulator R, capacitor C
It is provided in the middle of the hollow frame 20.

Therefore, when the detector 5 (limit switch LS) is activated, the controller 6 stops both of the traveling motors 4 that were rotating in the normal direction, and then stops both of the traveling motors 4 that are rotating normally.
Then, one of the traveling motors 4 is stopped and the other is reversed, then both traveling motors 4 are stopped, and then both traveling motors 4 are rotated in the normal direction. Each time the detector 5 is activated, the operation of stopping one of the traveling motors 4 and reversing the other one is alternately performed.

The cable 7 is capable of supplying power to the submersible pump 2 and the left and right running motors 4 from a power source outside the pool 100.

In this example, a buoyant coaxial device is used and connected to the power supply box 30.

The power supply box 30 is placed at a poolside, etc., and includes indicator lights WL, PL, fuses F1, F2, earth leakage breaker FLCB, and 24-hour timer TR, and a plug (not shown) connected to a commercial power outlet. ) is provided.

The remote controller 8 is capable of remotely controlling the left and right traveling motors 4.

In this example, a push button switch is connected to the power supply box 30 and stops the left and right traveling motors 4, respectively.
It consists of a BSR and a BSL, and can be operated remotely by a worker located at the poolside or elsewhere.

Next, the operation will be explained based on such a configuration.

Figures 1 to 3 show a pool 10 that stores water.
FIG. 4 shows a state in which the pool cleaner 1 is submerged in the water and the wheels 3 are brought into contact with the bottom surface 101 of the pool cleaner 1.
A state in which the plug of the power supply box 30 is not connected to the power outlet is shown.

In this state, set the 24-hour timer TR to a desired time within 24 hours, and connect the plug to the power outlet.

Then, the motor 11 of the submersible pump 2 and the motor 21 of the travel motor 4 are activated.

When the motor 11 is started, the pump 10 rotates, and the sediment on the pool bottom 101 is sucked in from the suction port 12 along with the water in the vicinity, and is discharged from the discharge port 13.

Sediment and water from the discharge port 13 are passed through the filter 14
The water is separated and stored inside the filter 14, and the water passes through the filter 14 to the pool 10.
Ejected within 0.

When the left and right motors 21 are started, their rotation is reduced by the reducer 22 and each drive wheel 16 rotates normally.

For this reason, the pool cleaner 1
(A in Figure 5).

When the pool cleaner 1 reaches one side of the pool side 102 and the bumper 26 comes into contact with it, the guide rod 25, the bumper 26, and the connecting rod 2 resist the elasticity of the spring 27.
8. The operating rod 29 moves back and the limit switch 24
(LS) closes.

When limit switch LS is closed, the normally open contact of auxiliary relay The left and right motors 21 are stopped.

For this reason, the pool cleaner 1 is stopped (fifth
Figure B).

After the set time of timer T1, its normally closed contact is opened and its normally open contact is closed, so the normally closed contact of auxiliary relay X1 is returned to the closed state, and the normally open contact of auxiliary relay X2 is returned to the closed state. When the contacts are closed, the two switching contacts of the auxiliary relay X2 are switched to the inside of FIG. 4, and the left and right motors 21 are reversed.

Therefore, the pool cleaner 1 moves backward (C in FIG. 5).

At this time, the bumper 26 is removed from the pool side 102, so the limit switch LS is opened.
The normally open contact of auxiliary relay X3 is self-maintained in a closed state.

After the set time of timer T2, its normally open contact closes and its normally closed contact opens, so the normally closed contact of auxiliary relay X1 is opened, and the normally open contact of auxiliary relay X2 is returned to the open state. At the same time, the two switching contacts of the auxiliary relay X2 are returned to the outer state shown in FIG. 4, and the left and right motors 21 are stopped.

Therefore, the pool cleaner 1 stops (D in FIG. 5).

After the set time of timer T3, its normally open contact is closed, so the normally open contact of auxiliary relay X2 is closed, and the two switching contacts of auxiliary relay X2 are switched to the inside as shown in FIG. It will be done.

At this time, the switching contact of the ratchet relay RR is
Since it is switched to the right side in FIG. 4 and the normally closed contact of the auxiliary relay X1 is opened, the right motor 21 is stopped and the left motor 21 is reversed.

Therefore, the pool cleaner 1 is turned backward and to the right by 180 degrees (E in FIG. 5).

After the set time of timer T4, the normally closed contact of timer T4 is opened, so that the normally open contact of auxiliary relay X2 is returned to the open state, and the two switching contacts of auxiliary relay be returned.

At this time, since the normally closed contact of the auxiliary relay X1 is open, the left and right motors 21 are stopped.

For this reason, the pool cleaner 1 is stopped (fifth
Figure F).

After the set time of timer T5, the normally closed contact of timer T5 is opened, so that the normally closed contact of auxiliary relay X1 is returned to the closed state, and the left and right motors 21 rotate normally.

Therefore, the pool cleaner 1 cleans the pool side surface 102.
(G in Figure 5).

At this time, everything except the switching contacts of the ratchet relay RR returns to the state shown in FIG. 4.

From then on, each time the pool cleaner 1 reaches the pool side 102 and the limit switch LS is operated to close,
The switching contact of the ratchet relay RR is switched, and the operation of stopping one motor 21 and reversing the other motor 21 is alternately performed.

Therefore, the pool cleaner, as shown in FIG.
It moves back and forth between the pool side surfaces 102 while being moved in one direction (in the direction of the arrow), cleaning the entire area of the pool bottom surface 101, and stops after the set time of the 24-hour timer TR to complete the cleaning work.

Next, push button switch BSR of remote controller 8,
When either BSL is pressed, either the left or right motor 21 is stopped, so the pool cleaner 1 can be turned around.

Therefore, when cleaning a part of the pool bottom surface 101, do it like this.

Although the pool cleaner 1 was used in a swimming pool in the previous embodiment, the present invention is not limited thereto, and may be used in, for example, a bathtub, an aquarium, a fish pond, etc.

In the previous embodiment, the pool cleaner 1 constituted a so-called body by the pump casing 17, the frame 18, the motor casing 19, and the hollow frame 20, but the present invention is not limited to this, and a dedicated body may be provided, for example.
