DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an oil changer for changing oil such as engine oil.

[0002]

2. Description of the Related Art Generally, engine oil is used in engines of automobiles and the like for the purpose of preventing internal wear, sealing and cleaning. Such engine oil is used under a high temperature condition of 100 ° C. or more when the engine is started.

[0003] Such an engine oil is gradually oxidized and deteriorated by being used at a high temperature for a long period of time. Oxidation and deterioration may cause corrosion and wear of bearings and the like. The engine oil is gradually polluted by soot generated by incomplete combustion of fuel when the engine is driven, unburned raw gas, and the like. Furthermore, if unburned raw gas is mixed into engine oil, the oil viscosity will decrease. If the engine oil is used in such a contaminated state or in a state in which the oil viscosity is reduced, each part in the engine will be worn.

As described above, the use of an engine oil for a long period of time causes oxidative deterioration, contamination, oil viscosity, and the like, thereby deteriorating its function. Since this may cause engine trouble, check the color tone and viscosity,
Or after a period of use, it is necessary to change the oil.

Conventionally, such an oil change has been performed as follows. First, old oil flows down and is discharged from an oil outlet provided in an oil pan at the bottom of the engine, and then new oil is injected from an oil inlet provided in an engine head. .

However, in general, in an automobile, the bottom of the engine is located near the ground. For this reason, when opening / closing the discharge port for discharging oil, first, the vehicle is lifted by a jack or the like, and the worker goes underground between the vehicle and the ground. Such an operation is time consuming and rather cumbersome.

[0007] For this reason, an oil changer for discharging oil from the engine head has been proposed at present. This oil exchanger uses a recovery pump, which is connected to a suction pipe formed of a thin tube and a waste oil tank. Then, the suction pipe is inserted from the oil level gauge at the engine head to the bottom of the oil pan, and the recovery pump is driven. As a result, old oil is sucked from the suction pipe and discharged and collected in the waste oil tank. After the old oil is sucked, new oil is injected from the oil inlet according to the suction amount. By using such an oil changer, it is not necessary to dive into the lower part of the vehicle at the time of oil change, and the work becomes easier.

[0008]

However, the conventional oil changer only discharges and recovers old engine oil from an oil level gauge. Therefore, the following is a problem. In other words, there are a plurality of types of automobile engines, and in a place where oil is changed as a business, it is necessary to prepare a plurality of types of engine oil correspondingly. For this reason, conventionally, engine oil contained in a drum can stored in an oil storage is divided into light-shielding containers or the like for each type and stored in a work space. At the time of oil injection, a corresponding type of oil is selected, the required amount is transferred to a container such as an oil mug, and the oil is carried to a car for injection work.

As described above, conventionally, in a work space,
It is necessary to secure a storage space for the engine oil that has been subdivided and an installation space for the oil changer. In this,
As the work space is reduced, the work space becomes more cluttered, which hinders the work and walking of the worker. In this case, a problem occurs in work safety.

The operation of selecting the corresponding type of engine oil, grasping the required amount thereof and transferring it to an oil jug, and the operation of injecting the oil into the engine are both time-consuming and troublesome. Further, when the oil is divided into small pieces and stored in the work space, the number of times of replenishing the oil from the drum can increases. In such a state, the working efficiency is not good. In particular, at a gas station, if the working efficiency is poor, many drivers are kept waiting for a long time, which is a problem in sales.

The present invention has been proposed to solve the above-mentioned problems of the prior art. The first object of the present invention is to reduce the installation space for an apparatus for oil change and reduce the working space. It is an object of the present invention to provide an oil changer that can be widely secured and can perform an oil change operation safely. A second object is to provide an oil exchanger capable of performing an oil discharge / collection operation with high efficiency.
A third object is to provide an oil exchanger capable of performing an oil supply operation with high efficiency.

[0012]

In order to achieve the above object, the invention according to claim 1 is characterized in that a gantry and a tank portion are provided above the gantry, and one or two tanks are provided inside the tank portion. The above-mentioned tank is provided, and an oil recovery section and an oil supply section are provided inside the gantry.

It is characterized in that it is configured as manual supply means for manually removing oil.

[0015]

In the oil changer according to the first aspect of the present invention, the oil recovery section and the oil supply section are provided inside the gantry, and the oil tank section is provided above the gantry. The installation space (area) for oil change is reduced as compared with the case where it is provided. Thereby, a wide work space can be secured, and work safety is improved. In addition, since at least the front of the gantry and the tank is provided with panels, it looks like a wall except for opening the panels at the necessary points during use, and the pumps etc. placed inside the gantry are invisible. It will be in order. In addition, the panel can prevent the suction pipe, the oil supply pipe, and the like from protruding to the front of the gantry except during use, thereby improving work safety.

Further, according to the first aspect of the present invention, the waste oil receiver of the waste oil discharging means can be pulled out forward, or the waste oil receiver is fixedly arranged and the upper panel is provided so as to be openable forward as a waste oil guide. Therefore, unnecessary oil can be collected from the outside in the waste oil receiver. For this reason, in addition to the automatic recovery by the pump, the present invention can be used for oil exchange by discharging oil from the lower part of the conventional engine. Moreover, the waste oil pan pulled out forward,

If the refueling nozzle 28 is different from the selected type, the supply pump 13 is not driven even if the opening / closing grip 28a is opened, so that different oil is not supplied into the engine.

[Manual oil change operation] In recent years, it has become common to extract old oil from an oil level cage for oil change. However, users have been required to remove old oil from the oil bottom of the engine as usual. It is not uncommon for them to want to be discharged from the exit. In this case, the old oil is discharged by lifting the automobile with a jack or the like and discharging the oil to a container or the like as in the related art.

Then, in the oil exchanger of the present embodiment, the oil thus discharged is collected in the waste oil discharging means as follows. That is, first, the waste oil receiver 8a
Is pulled out of the connected front panel 18d. As a result, the internal waste oil receiver 8a is drawn forward. Also,
Accordingly, the discharge pipe 8b connected to the waste oil receiver 8a is also drawn out. Then, the oil in the discharge container is discharged onto the strainer 8c of the waste oil receiver 8a. This allows
The solid matter in the oil is removed, and only the oil is
a is discharged to a waste oil tank via a discharge pipe 8b.

After that, the injection of new oil into the engine is performed not only by the oil supply unit of the oil changer but also by manually taking out the necessary oil into the oil mug and supplying it to the engine in the same manner as described above. it can.
For this, first, the front panel 18e of the manual supply means is opened, and the oil jug 33 is placed on the oil pan 32. Thereafter, a corresponding oil outlet is selected from the three branch pipe oil outlets 30. Then, the opening / closing means is opened / closed to collect a required amount. The oil collected in the oil jug is injected into the engine from the oil inlet.

At this time, if oil spills on the oil pan due to erroneous operation of the opening / closing means or spillage from the oil mug, the oil is transferred to the upper part of the oil pan 3 made of a strainer.
It passes through 2a and accumulates in the lower portion 32b of the oil pan. The oil accumulated in the lower portion 32b of the oil pan is collected as follows. That is, first, the waste oil receiver 8a of the waste oil discharging means is drawn out. Next, the lower portion 32b of the oil pan is pulled out and taken out. Then, the oil in the lower portion 32b of the oil pan is discarded in the waste oil pan 8a. As a result, unnecessary oil is collected. Further, the used oil mug draws out the waste oil receiver 8a, places it face down on a strainer, and drains the oil.

(3) Effects of this embodiment The effects of this embodiment as described above are as follows. That is, in this embodiment, the oil recovery unit X and the oil supply unit Y are housed in the same gantry 1 and

A configuration in which only the oil supply pipe 16 is provided outside the panel and the oil supply pipe 16 is pulled out from the draw-out hole as needed
It is also possible to adopt a configuration in which the oil supply pipe 16 is provided outside the panel by a drawing hole.

Further, the waste oil meter 6 provided in the oil collecting section X of the present invention is not limited to storing the collected one engine oil therein and measuring its capacity. A configuration in which the flow rate flowing through the pipe is added and displayed is also possible.

Further, in the present invention, the waste oil tank is not limited to being provided underground, and a collection container such as a pail can is disposed inside the gantry 1 below the waste oil receiver 8a, or provided outside the equipment installation location. It is also possible to connect via piping.

In the present invention, the configuration of the waste oil receiver 8a is not limited to the above-described embodiment, but may be configured as follows. For example, a front panel on the front of the waste oil receiver may be provided so as to be openable and closable, and the panel may be opened when necessary to draw out the waste oil receiver. Further, in addition to the configuration in which the waste oil receiver is drawn out to the front, for example, a configuration as shown in FIG. That is, the waste oil receiver 8a is fixedly arranged. Then, the front panel 18f at the upper position is configured as a waste oil guide which can be folded forward with the position of the front upper end of the waste oil receiver 8a as a fulcrum.

With such a configuration, when recovering old oil manually or collecting oil accumulated in the oil receiving tray 32 of the manual supply means, the front panel 18f in the form of a waste oil guide is tilted forward. As a result, an upper portion in front of the waste oil receiver 8a is opened, and the oil can be discarded from the opening. The discarded oil flows down to the waste oil receiver along the panel inner surface serving as a guide and is collected. In such a configuration, the waste oil receiver is fixedly arranged and is not drawn out to the front, so that the discharge pipe connected thereto can also be fixedly arranged, which facilitates assembly. Further, the strainer used as a solid removing means or an oil drain provided in the waste oil receiver may be detachably provided and used as needed. Further, the solid removing means is not limited to the strainer, and a filtering means such as a filter may be used, or a double structure of the strainer and the filtering means may be used.

Further, in the present invention, the waste oil discharging means may be configured such that the oil receiving tray 32 is not provided by disposing the waste oil receiver 8a at the position of the oil receiving tray 32 on which the oil jug is placed. In this case, the waste oil receiver 8a is far from the position of the suction pipe 3, and the waste oil pipe becomes longer. However, since the waste oil pipe is also used without providing the oil receiver, the number of members can be reduced. Further, in this configuration, it is possible to provide a parts washing tank or the like at the position where the waste oil discharging means is arranged in the above-described embodiment. Thereby, the related work can be performed at one place, so that the work efficiency can be improved.

Further, in the present invention, the tank portion 2 is not limited to being divided into three, and may be configured to be divided into two or into a plurality. Also, the internal capacity of each tank is not limited to 250 liters, but can be larger or smaller. Furthermore, the oil stored inside is for luxury cars, fuel-efficient cars,
Various engine oils corresponding to economy, diesel, washing in the engine, various grades, two or four cycles, etc. can be appropriately selected and put. Then, the operator can appropriately select and use the type of engine oil from the tank according to the engine of an automobile such as a sports car, a family car, and a commercial vehicle.

Further, in the present invention, the entire periphery of the gantry 1 and the tank portion 2 above the gantry 1 are not limited to being covered by the panel 18, but at least the front surface may be covered. This contributes to an improvement in work efficiency and can facilitate the configuration. In particular, a configuration in which the suction pipe 3 and the oil supply pipe 16 are taken out from the side surface, or each nozzle 2
In the case of a configuration having 5, 28 holding portions, or when maintenance and inspection of the pump can be performed from the rear, the number of front panels that need to be opened and closed is reduced, and the configuration is simplified.

Further, the panel 18 is not limited to the same color as the whole, but may have different colors for the gantry 1 and the tank portion 2 and for the purpose of use of the oil recovery portion X and the oil supply portion Y. It is also possible to change the color or add pictures and characters.
