Description

Oil changer for automobiles {Oils Merchandiser of Automobile}

The present invention relates to an oil changer used to replace engine oil or mission oil of a vehicle. More specifically, the present invention relates to an oil changer of an automobile, which enables to safely collect waste oil in a vehicle and to easily inject new oil. It is about.

As is well known, the engine or transmission of an automobile is a combination of many mechanical parts that are organically coupled, so that lubricant is injected for smooth operation.

Lubricant forms an oil film on the friction surface of each part to reduce friction and abrasion while cooling the friction surface and suppressing corrosion. To this end, lubricating oil must maintain an appropriate viscosity. When the vehicle is operated for a certain period of time, the lubricating oil is lowered, so that the lubricating function is greatly reduced or lost.

In particular, in the case of engine oil, there is a high possibility of causing a failure by being stuck to the engine parts by high heat because it contains a large amount of foreign substances such as powdered powder due to partial oxidation and surface wear. Therefore, after using lubricant for a certain period, it should be discharged and replaced with new oil.

On the other hand, the oil discharged from the vehicle must be collected and disposed of separately as waste oil to prevent environmental pollution.

Such a method of oil change in a vehicle is carried out by lifting the vehicle properly by a lift, etc., and then placing a container such as a bucket or a can under the vehicle, for example, releasing the drain plug installed in the drain pan under the engine to discharge the waste oil and then draining the drain oil. It is common to lock the plug, open the oil cap on the top of the engine, and add fresh oil using a funnel.

However, this replacement method is not only complicated to change the oil, but also difficult to accurately collect the waste oil without leaking to the outside, and the collected waste oil must be transferred to a separate collection tank again to prevent the scattering or spillage of the waste oil to some extent. I was forced to take.

Accordingly, in recent years, as provided in Korean Utility Model Registration No. 113250 or Utility Model Publication No. 98-33371, a waste oil collector capable of easily and safely collecting waste oil has appeared, and Utility Model Registration No. 126763 Similarly, automatic oil changers are being introduced to drain waste oil by pumps and to add fresh oil.

However, in the case of automatic oil changer, the structure is complicated and expensive, and there is a problem that it is a big economic burden in maintenance centers such as general car centers. Especially, since the front wheel oil and the rear wheel oil have different viscosity, It had to be replaced or had to have a dedicated device.

In addition, when only the waste oil collector is made, the waste oil can be easily collected. However, since the oil has to be manually filled when the new oil is injected, the work is complicated and the inconvenience of having to check the oil gauge is often accompanied.

The present invention was devised to solve the above-mentioned problems. The waste oil such as engine oil or transmission oil can be safely collected without spillage, and new oil can be easily lubricated, yet the structure is simple and can be supplied at low cost. It is an object of the present invention to provide a vehicle oil changer.

Another object of the present invention is to provide an oil change device for a vehicle that can simultaneously store the front wheel drive and rear wheel drive mission oil and supply the oil as needed.

Although these waste oil nozzles 31 and oil nozzles 33 of the new oil are not shown, the oil tank 10 may be stably equipped with hook means such as a hook.

In addition, two new oil reservoirs 12 of the oil tank 10 are connected to the compressor, and pressure supply valves 40 for selectively supplying compressed air into each new oil reservoir 12 are respectively installed. .

Each pressure supply valve 40 displays the pressure in the new oil reservoir 12 when new oil is injected, and actuates the pressure in the new oil reservoir 12 by operating the safety valve 42 when excessive pressure is applied. A pressure gauge 41 is provided to keep it below a certain state.

On the other hand, when compressed air is supplied to the new oil storage unit 12 to inject new oil in this way, a deformation may occur in which the partition wall 13 protrudes convexly toward the waste oil storage unit 11 at atmospheric pressure. In this case, there is a fear that the junction of the partition 13 falls.

Accordingly, at least one support rod 16 is installed in the waste oil storage 11 to prevent deformation of the partition 13 by air pressure between the two partitions 13.

In addition, preferably the frame 17 is bonded to both lower sides of the oil tank 10, the wheels 18 are installed on both lower ends of each frame 17 to facilitate the movement of the oil tank (10).

And one frame 17 is provided with a handle 19 for moving the oil change device. In addition, a tool box 50 is installed on the upper outer circumferential surface of the oil tank 10 for the convenience of the operator.

Next, the operation of the oil change device of the vehicle according to the present invention configured as described above will be described.

First, two new oil reservoirs 12 of the oil tank 10 are filled with different oils, for example, engine oil and mission oil, or a front wheel mission oil and a rear wheel mission oil through respective inlets 12a. do. At this time, the amount of new oil injected can be confirmed by the level indicator 15.

In this state, when the engine oil or the mission oil of the vehicle is to be replaced, the vehicle is appropriately lifted by a lift or the like and the oil change device of the present invention is moved to the lower portion of the vehicle.

Subsequently, the funnel 20 is positioned to correspond to the waste oil discharge part of the vehicle, and then the guide tube 21 is lifted to an appropriate height through the fixing knob 23 to fix the position.

Next, the valve 24 of the guide tube 21 is opened and the drain plug installed in the drain pan of the vehicle is released. Then, the waste oil which has already been used from the drain pan of the vehicle is discharged to the funnel 20 directly below, and is collected along the inside of the guide tube 21 to the waste oil storage unit 11 of the oil tank 10. When the waste oil discharge is complete, lock the drain plug again and move the oil changer to the side of the vehicle.

Next, open the engine hood, open the oil cap while the vehicle is put down, and connect the pressure supply valve 40 of the new oil reservoir 12 in which the oil to be injected from the oil changer 10 is stored to the compressor. Compressed air is supplied into the new oil reservoir 12.

Subsequently, a new oil nozzle 33 and a hose are inserted into an oil inlet such as an engine, and then the valve 34 is opened. Then, the new oil filled in the new oil reservoir 12 is discharged by the air pressure of the compressor, so that the oil can be simply injected into the engine.

At this time, since the amount of oil to be injected can be accurately understood through the level indicator 15 provided in the new oil storage unit 12, it is not necessary to check the oil gauge such as an engine at any time.

When fresh oil is injected in the required amount, the valve 34 is closed, disconnected from the compressor, or stopped from running.

As such, when excessive pressure is applied to the new oil reservoir 12 when the new oil is injected, the safety valve 42 provided in the pressure supply valve 40 is operated to maintain the constant pressure or less.

Meanwhile, when the waste oil is collected in the waste oil storage unit 11, the hose is connected to the waste oil outlet 11a of the waste oil storage unit 11, the waste oil nozzle 31 is connected to the end of the hose, and then the waste oil nozzle ( 31) into a separate waste oil tank and open the valve (32) to discharge.

At this time, although not separately shown, it is also possible to install the pressure supply valve in the waste oil storage unit 11 to discharge the waste oil by pneumatic pressure by the compressor.

And, when a large amount of foreign matter, such as ear powder, accumulated on the bottom of the waste oil storage unit 11, the foreign matter discharge port 11b is opened and removed.

Although the oil tank 10 of the present invention has been described as having one waste oil storage unit 11 and two new oil storage units 12 by the partition wall 13, the present invention is merely a mere example. Of course, it is not limited and may be changed in various forms.

For example, the new oil storage unit consists of three to store the engine oil, the front wheel mission oil and the rear wheel mission oil, respectively, it is revealed that each oil storage unit can also be divided into concentric circles rather than partitions.

As described above, according to the oil change device of an automobile according to the present invention, it is possible to safely collect waste oil such as engine oil and transmission oil without spillage, and also to obtain new oil by using a compressor provided in a maintenance shop. Oiling makes the oil change work simple.

In particular, the engine oil as well as the front-wheel drive and rear-wheel drive mission oil at the same time to store the oil can be easily supplied as needed.

In addition, as a very simple structure that does not include a pump or the like, it can be supplied at low cost to a maintenance center such as a car center, and a tool box is integrally provided in the oil tank, so that maintenance work can be facilitated.

Therefore, the present invention has an excellent effect of contributing to the convenience of automobile oil exchange and ensuring the safety of waste oil collection, as well as useful in terms of economics.
