Abstract

PURPOSE:To enable petroleum within an oil receiving pan of a petroleum equipment to be discharged within a short period of time without applying any troublesome operation by a method wherein an adapter is fixed to an end cap of a cartridge tank and the interior of the cartridge tank is evacuated by a negative pressure generating means. CONSTITUTION:A vacuum pump is stored within a cartridge tank. This pump is provided in order to evacuate the interior of the cartridge tank in case that oil is supplied from a petroleum tank such as a polyvinyl chloride tank and the like. An end cap fitting part 9 of the cartridge tank 1 having a negative pressure generating means has threadably an adapter 11 having an opening 10 for sucking petroleum which reaches near a bottom surface of an oil receiving pan 2 of the main body of the equipment. The opening 10 is provided with a ball valve 11a acting as a check means. In addition, a sponge 12 of continuous foam material is arranged below the opening 10 so as to provide an action of filter and a shock-absorbing operation in case that the opening 10 is contacted with the bottom surface of the oil receiving pan 2. In this way, as the interior of the cartridge tank 1 is evacuated, petroleum 3 is sucked and discharged.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an oil draining device for oil-burning equipment using a cartridge tank, such as oil-fueled oil stoves and fan heaters.

Conventional technology When storing an oil stove etc. in a warehouse during the off-season, or when transporting it during a move, it is necessary to remove the oil from the main body of the device. , the oil pan was empty after all the oil had been burned.

Problems to be Solved by the Invention The conventional method of suctioning with a dropper has the problem of not being able to suction a large amount at once, but taking up small amounts at a time, which is time-consuming.The method of using petroleum-burning plaster has the following problems. Ta.

■ In the off-season, when heating is not necessary and it is warm, the room temperature would rise too much if I operated the petroleum equipment indoors, so I reluctantly took it outside to operate it.

■ With oil fan heaters, when the oil level becomes low, the electromagnetic pump may become louder and generate vibrations.
This may shorten the life of the electromagnetic pump.

Therefore, an object of the present invention is to drain oil from a pan of an oil pan in a short time and without much effort.

Means for Solving the Problems and In order to achieve the above object, the present invention provides a cartridge tank for sucking oil from a tray in the main body of the device by negative pressure generating means, and a cartridge tank provided at the lower part of the cartridge tank. The device is equipped with a cap, an adapter that covers the cap and has an oil receiver in the device body that reaches near the bottom of the dish, and has an opening at the bottom for sucking in oil, and a non-return means provided in the opening.

Function: The oil draining device for oil burning equipment of the present invention has the above-mentioned configuration, and when the adapter is attached to the base of the cartridge tank and the inside of the cartridge tank is made negative pressure by the negative pressure generating means, the oil receiver of the equipment main body is drained inside the cartridge tank. Oil is sucked into the cartridge tank in a short period of time.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 3, reference numeral 1 denotes a cartridge tank having a negative pressure generating means (not shown), and in this embodiment, a vacuum pump is built in the cartridge tank. This is to create a negative pressure inside the cartridge tank when refueling the cartridge tank from an oil tank such as a plastic tank. It also includes a device that connects the cartridge tank 1 with a separate vacuum generator to generate negative pressure in the cartridge tank 1.

In order to suck up the oil 3 in the pan 2, the oil pan on the main body of the oil-burning equipment is connected to a cap 4 provided at the bottom of the cartridge tank 1, and the oil pan on the device body, which covers the cap 4, is located near the bottom of the pan 2. An adapter 6 having an opening 6 at the bottom for sucking in oil is attached to the stepped portion 7 of the cap 4 so as to cover the cap 4. As the non-return means 8, a ball valve which is normally closed by its own weight and oil pressure is provided.

Next, the operation of the configuration of this embodiment will be explained. When the inside of the cartridge and the receiving tank 1 become negative pressure by the negative pressure generating means, the oil 3 in the pan 2 is sucked into the cartridge tank 1 through the opening 6, and the oil pan moves from the pan 2 in a short time. Oil is discharged.

In the embodiment shown in FIG. 2, the oil receiver of the main body of the instrument reaches near the bottom of the dish 2 and has an opening 10 at the bottom for sucking oil 3 into the mouthpiece attachment part 9 of the cartridge tank 1 having negative pressure generating means. The adapter 11 is screwed together. A ball valve 11a is provided in the opening 1o as a check means. Furthermore, at the bottom of the opening 1Q, there is a sponge 1 made of open foam.
2 is provided, and the oil pan serves as a filter and as a buffer in case the opening 1o comes into contact with the bottom surface of the dish 2.

Next, the operation of the configuration of this embodiment will be explained.

The cap (not shown) of the cartridge tank 10 having a negative pressure generating means is removed, and the adapter 11 of the present invention is screwed into the cap mounting portion 9 of the cartridge tank 1. Since the opening 1o of the adapter has an oil pan close to the bottom of the pan 2,
When the inside of the cartridge tank 1 is made negative pressure, the oil 3 is sucked and discharged. Since the filter 12 is provided, dirt and the like adhere to the filter 12, and the filtered oil can be sucked and discharged.

The embodiment shown in FIG. 3 has the same configuration as the embodiment shown in FIG. There is. This convex portion may be provided all around the circumference, or may be one or more partial convex portions, and the oil pan only needs to be able to secure a gap 4a between the bottom surface of the dish 2 and the opening 15. The operation is similar to the embodiment shown in FIG.

In this embodiment, the convex portion 14 is intentionally placed on the oil pan 2.
The oil pan is brought into contact with the bottom surface of the pan 2 to minimize the amount of oil remaining at the bottom of the pan 2.

The embodiment shown in FIG. 4 shows an adapter 16 that is held in the base 4 similarly to the first embodiment.

The adapter 16 includes a permanent magnet 17, an opening 18, and the opening 1.
An adapter main body 20 having a ball 19 as a non-return means of 8 is fixed. A gasket 22 is provided to seal the outer periphery of the opening 21 of the cap 4.

In this embodiment, the adapter 16 connects the permanent magnet 17 to the base 4.
Since the adapter 2o is attracted and held by the magnetic attraction force, it is convenient to attach the adapter 2o with one touch.

Effects of the Invention As described above, the present invention provides an adapter that sucks oil from the pan into the oil pan of the main body of the device by means of generating negative pressure, and an adapter is provided on the mouthpiece of the cartridge tank, and the oil pan sucks oil from the pan into the cartridge tank. It can be discharged in time.

In addition, according to the present invention, by screwing an adapter into the base mounting portion of the cartridge tank, the oil pan can drain oil from the pan into the cartridge tank in a short time.

In addition, the present invention provides an oil pan near the oil draining opening of the adapter with a convex part that can come into contact with the bottom of the pan, so that the oil pan will not be blocked by the bottom of the pan. can be sucked and discharged into the cartridge tank. moreover,
If the convex portion is in contact with the bottom surface, the oil pan can stably drain the oil remaining in the pan to a minimum.

Furthermore, if a magnetic attraction means is incorporated into the contact surface of the adapter with the base, the adapter can be held in the base with one touch, making it easy to use.
