A motor 24 is coupled with the above-mentioned pump 17, and a surface level sensing switch 25 is equipped, which will be opened when liquid is sensed at the upper part of the above- mentioned waste oil display vessel 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile oil draining device used at automobile gasoline filling stations and the like.

The oil extraction device for such automobiles sends the engine oil taken out from the oil pan through a extraction nozzle into a waste oil display container, leaving it in a state where it can be left from the outside, and then discarding it into the waste oil tank. It is something.

The purpose of the present invention is to use such a device for removing oil from a J vehicle, to quickly perform the work from extraction to sending it to the waste oil tank, and to make effective use of one pump to reduce the number of parts. The goal is to provide equipment that can be manufactured in large quantities at low cost.

However, this object is achieved according to the present invention by connecting the extraction nozzle, the waste oil tank, and the waste oil display container via a single pump that can be controlled to rotate in forward and reverse directions.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing a service device incorporating the device of the present invention.
．． An air nozzle 4 and a washing water nozzle 5 are suspended through the air nozzle 4 and the washing water nozzle 5, and a faucet 6, an air pressure display 17, etc. are provided on the surface of the external device, and a vacuum cleaner etc. may also be provided.

a waste oil display container 8 on the exterior 2 of the service equipment 1;
A buzzer 9, a hose 12 having a nozzle 11 at its tip via a connector 10, and a key switch 13 incorporating relays R1 and R2 to be described later are provided.

FIG. 2 is an explanatory diagram showing an embodiment of the apparatus of the present invention, in which the bow 12 is wound around a hose retractor (hose reel) 14, and the end thereof is connected to a pipe that communicates with a spout nozzle 8a in a waste oil display container 8. Connect to 15. A check valve 16 is installed in the middle of this piping 15, and a pump 17 that can control forward and reverse rotation.
and a naenok valve 18, and a branch between the check valve 16 and the pump 17, and a discharge pipe 19 is installed.

A check valve 20 is provided in the middle of the discharge pipe 19, and the tip thereof is inserted into a waste oil tank 21.

Further, a discharge port 8 is provided at the bottom of the waste oil display container 8 by branching between the pump 17 of the pipe 15 and the check valve 18.
A check valve 23 is provided in the middle of the piping 22, with several piping 22 communicating with the piping 22.

On the other hand, a motor 24 is connected to the pump 17, and a liquid level detection switch 25- is attached to the upper part of the waste oil display container 8, which opens when liquid is detected. In the figure, 80 is a weight type provided in the container 8.

As shown in FIG. 3, the liquid level detection switch 25 is inserted between one contact a of the key switch 13 and the relay R1,
The other contacts of the key switch 13 and the series circuit of the relay R2 are connected in parallel to the series circuit of the key switch 13, the liquid level detection switch 25, and the relay R1, and the buzzer 9 is connected in parallel to the relay R2. Furthermore, as shown in FIG. 4, the relay contact R+' of the relay R1 is connected to the forward rotation circuit of the motor 24, and the relay contact R2 of the relay R2 is connected to the reverse rotation circuit of the motor 24.
’ is inserted.

Next, to explain how to use it, service equipment 1 is installed at a gasoline service station with a relay, an air nozzle 4
Fill the tire with air using the cleaning water nozzle 11.
The faucet 6 is used to wash the car body, tires, etc., and the faucet 6 is used to wash the hands.

To drain a car's engine oil using this force/hiss device 1, insert the nozzle 11 into the oil pan, and use the key to move the key switch 13 to the "Drain" position.
-, the contact a closes, the relay R1 is energized via the closed liquid level detection switch 25, the contact R1/ is closed, and the motor 24 rotates normally.

As a result, the pump 17 also rotates in the normal direction, and engine oil is sucked up from the nozzle 11 and passes through the hose 12 to the piping 15.
Enter the check valve 16. Pump 17, check valve 18
The waste oil is ejected from the end of the nozzle 8a into the waste oil display container 8 through the nozzle 8a.

Once all the oil has been drained into the container 8, the motor 24 will be stopped by returning the key switch 13 to the OFF position.

Next, in order to drain the oil in the container 8 to the waste oil tank 21, switch the key switch 13 to the "drain" position, the contact will close, the relay contact R2 and the buzzer 9 will be energized, and the relay contact R2' will close. The buzzer 9 sounds as the motor 24 rotates in reverse.

The pump 17 is also driven in reverse by the motor 24, and the oil in the container 8 is discharged from the outlet 8b to the pipe 22.
Enters the discharge pipe 19 through the check valve 23 and the pump 17, and passes through the check valve 20; to the Guan oil link 21 ()1
Served.

When all the oil is sent to the waste oil tank in this way and the container 8 is empty, turn the key switch 13 to roffJ.
The motor 24 and the buzzer 9 are stopped by returning the program to 1, but since the buzzer 9 continues to sound until then, it is possible to prevent forgetting to stop at the end of the process.

Note that when oil accumulates in the container 8 and reaches the liquid level detection switch 25, this opens, cutting off the power to the relay R1, opening the contact R1' and stopping the motor 24. This will prevent oil from overflowing.

Further, since the switch 13 is operated by key operation, the administrator can operate it while confirming safety, so there is no danger and there is no risk of tampering.

As described above, in the automobile oil extraction device of the present invention, the extraction nozzle, the waste oil tank, and the waste oil display container are connected via one pump that can control forward and reverse rotation. Oil from a waste oil display container.

The oil can be discharged quickly by the power of the pump, and since this pump can be used in common with the pump for extracting oil from the oil pan of an automobile, it can be manufactured at low cost without increasing the number of parts.
