6 are provided. A pump switch 48 that rotates the motor 22 of the left pump 23 forward and backward is provided on the left operation switch plate 47 when facing the front. Further, a grip 28 for hanging the oil hose 31 in the middle is attached to the upper side surface of each of the columns 24 and 25.

Left and right symmetrical side covers 51 and 52 are attached to the left and right sides of the waste oil tank 11 and the upper cover 17, respectively. These side covers 51, 52 are formed in a shape that covers the side surface of the height from the lower portion of the waste oil tank 11 to the upper portion of the upper cover 17 in a curved shape from the front surface to the both side surfaces, and have openings 51a, 52a on the rear surface side, respectively. 52a is formed, covers the oil hose 31 portion led out from the suction pipe 33 of each pump 23, and leads each oil hose 31 to the outside through the openings 51a, 52a on the back side. . On the upper surfaces of the side covers 51, 52, there is provided a nozzle receiver 53 provided with three holes for inserting and suspending and holding three types of extraction nozzles 34 having different diameters and lengths. Note that reference numeral 55 in the figure is a power line for a commercial power source.

Next, the oil draining device 10 having the above structure
The operation of draining the engine oil will be described below. For the sake of explanation, the operation of the oil hose 31 on the right side will be described. First, an appropriate drain nozzle 34 is selected for the vehicle model of the vehicle from which oil is drained, the one-touch coupling 35 is used to connect to the tip of the oil hose 31, and this drain nozzle 34 is inserted into the oil level gauge hole of the vehicle engine. . Next, after confirming that the pump switch 45 of the operation switch plate 42 is in the off position, the power switch 43 is turned on. Next, the pump switch 45
Is put in the “drain”, the motor 22 on the right side rotates in the normal direction, the pump 23 sucks old oil of the engine from the drain nozzle 34 through the oil hose 31 and the suction pipe 33, and through the pump 23 and the discharge pipe 32. Waste oil tank 11
Drain into. When the suction of old oil is completed, the pump switch 44 is turned off. After that, the extraction nozzle 34 is pulled up from the engine and inserted into the nozzle receiver 53 to complete the oil extraction. At this time, by hanging the oil hose 31 in the middle of the handle 28, the oil hose 31 is prevented from hanging down. After completing the draining, pour new oil from the oil can to finish the oil exchange. The operation of draining the oil with the left oil hose 31 is also possible by operating the pump switch 48 of the left operation switch plate 46. That is, the oil removal of the two automobiles introduced on the left and right sides of the oil removal device 10 of the present invention can be performed simultaneously by the single machine.

Waste oil extracted from an automobile is a waste oil tank 1
When the inside of 1 is full, the float switch 16 operates and the indicator lamp 43 of full tank lights up, and when the pump is in operation, the pump is stopped. When the waste oil tank 11 is full, the worker inserts the one-touch coupling 35 of the oil hose 31 into a predetermined container, and puts the pump switch 45 or 48 on the oil hose 31 side into "discharging".
As a result, the motor 22 reversely rotates, and the waste oil in the waste oil tank 11 flows backward in the direction of the discharge pipe 32, the pump 23, the suction pipe 33, and the oil hose 31 and is discharged.

When operating at night, the operation switch plate 4
The illumination switch 27 in the hollow girder 26 is controlled by the illumination switch 46 of No. 2.
You can work by turning on.

According to the oil draining device 10 of the embodiment of the present invention having the above-described structure, one oil draining device is used for two
The oil of one car can be drained at the same time, which shortens the drain waiting time and improves the service to customers. Further, since it is illuminated by the illuminating device 27 built in the hollow girder 26, it is easy to use and has an excellent design. Further, since the upper cover 17 having the plurality of recessed portions 18 is provided above the waste oil tank 11. It is convenient because you can put tools that are in use.

Having described the preferred form of the invention,
It goes without saying that various improvements and modifications can be made without departing from the spirit of the present invention.
