DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described by way of an example in which the present invention is applied to an oil changing device for an automobile engine. As shown in FIG. 1, the oil exchange device 1 includes an oil extraction mechanism 3, an oil supply mechanism 4, an operation panel 5, a control device 6
Is provided.

The oil removal mechanism 3 includes a waste oil tank 7, a load cell 8 for measuring the waste oil tank 7, a waste oil pipe 9 connected to the waste oil tank 7, a waste oil pump 10 interposed in the waste oil pipe 9, and a waste oil pipe. 9 is connected to a waste oil hose 11.

[0007] The oil supply mechanism 4 includes a plurality of new oil tanks 1.
2, a load cell 13 for measuring each new oil tank 12,
It is composed of a new oil pipe 14 connected to the new oil tank 12, a new oil pump 15 interposed in the new oil pipe 14, and a new oil hose 16 connected to the new oil pipe 14.

Then, the waste oil hose 1 of the oil extracting mechanism 3
1 and each new oil hose 16 of the oil supply mechanism 4 are connected to a connector 17.
Can be attached and detached.

The operation panel 5 is provided with a touch panel 19. The control device 6 is provided with a guidance storage unit 6a. The control device 6 receives the signal of the input switch 19a of the touch panel 19 and controls each of the above-described devices. Are sequentially displayed on the display 19b of the touch panel 19.

Next, the operation will be described with reference to the flowchart of FIG. When the power switch (not shown) is turned on (ST
1), the control device 6 displays the work selection screen stored in the guidance storage unit 6a on the display 19a of the touch panel 19 (ST2 in FIG. 3). To change the oil of the car engine, press the portion on the touch panel 19 where the oil change operation is displayed, and when the oil change signal is input to the control device 6 (ST3), the control device 6 stores the oil change signal in the guidance storage section 6a. A refueling amount setting screen indicating the relationship between the vehicle type and the oil amount is displayed on the touch panel 19b (S
T4 FIG. 4).

[0011] Then, by pressing a part of the touch panel 19b on which the type of this car is displayed,
When the refueling amount setting signal is input to the control device 6 (ST5),
The control device 6 sets the amount of refueling, and displays on the touch panel 19b an oil type selection screen indicating the relationship between the oil type stored in the guidance storage unit 6a, the service period, and the traveling distance (S
T6 FIG. 5). Then, the customer hears the oil change cycle, monthly travel distance, and the like from the customer, presses the touch panel 19b of the portion where the desired oil type is displayed, and inputs an oil type selection signal to the control device 6 (ST7). An oil type is set, and the operation start screen indicating the oil extracting operation stored in the guidance storage unit 6a is displayed on the touch panel 19b.
(ST8, FIG. 6).

The designated nozzle 18 is connected to the connector 17, the nozzle 18 is inserted into the gauge hole of the oil pan of the automobile, and the touch panel 1 at the start is displayed.
9 and a start signal is input to the controller 6 (S
T9), the control device 6 drives the waste oil pump 10. The oil in the oil pan of the automobile flows into the waste oil tank 7 via the nozzle 18, the waste oil hose 11, the waste oil pump 10, and the waste oil pipe 9. Then, when the measured value of the load cell 8 does not change, the control device 6 stops the waste oil pump 10 and finishes oil extraction (ST10).

Next, the control device 6 drives the new oil pump 15 of the selected oil type. The oil in the new oil tank 12 is supplied to the oil pan of the automobile through a new oil pipe 14, a new oil pump 15, a new oil hose 16, and a nozzle 18. When the decrease amount measured by the load cell 13 reaches the set oil supply amount, the control device 6 stops the new oil pump 15 and the oil supply ends. (ST11).

Then, the control device 6 displays the work end screen stored in the guidance storage section 6a on the touch panel 19.
b (ST12, FIG. 7). In accordance with this display, the nozzle 18 is pulled out from the gauge hole, the amount of oil in the oil pan is checked, and all the oil changing operations are completed. The work end screen returns to the work selection screen after a predetermined time (ST13).

To replenish the new oil tank 12 with new oil, if a new oil replenishment operation is selected on the operation selection screen (ST14), guidance is displayed on the display 19b, and the replenishment operation of the new oil is performed. (ST1)
5). Further, in order to discharge the waste oil in the waste oil tank 7, if the waste oil discharge operation is selected on the operation selection screen (ST1).
6) Guidance is displayed on the display 19b, and the operation of discharging waste oil can be easily performed (ST17).
