Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil burning appliance which temporarily stores fuel oil from a cartridge tank in an auxiliary tank and supplies the fuel to a combustion section.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Publication No. 2-5234, for example, a tray is provided in an auxiliary tank, an oil supply port of a cartridge tank is provided, and a tray and an auxiliary A filter member was provided between the tank and the bottom surface, and the fuel oil in the cartridge tank was once stored in the auxiliary tank via the filter member and then supplied to the combustion section.

[0003]

However, in this conventional apparatus, since the weight of the cartridge tank is directly applied to the upper surface of the auxiliary tank, in order to reduce the number of times of refueling and reduce the trouble of the refueling operation as in recent years, When the tank has a large capacity such as 5 to 9 L, the cartridge tank itself is heavy and roughly mounted on the auxiliary tank, so that the auxiliary tank is damaged and fuel oil leaks out, or the upper surface of the auxiliary tank collapses. As a result, there is a problem that a certain oil level drops and causes abnormal combustion.

[0004]

The present invention focuses on this point and solves the above-mentioned drawbacks. In particular, the present invention is configured to supply the fuel oil to the combustion section while receiving the fuel oil and holding it at a constant oil level. An auxiliary tank, a filter tube detachably mounted in an opening provided on the upper surface of the auxiliary tank, a cartridge tank having an oil filler inserted into the filter tube and mounted on the upper surface of the auxiliary tank, the filter comprising: A filter that removes dust from fuel supplied from the cartridge tank to the auxiliary tank is provided on the peripheral wall, with a valve rod that stands up from the bottom and pushes up the valve device of the oil filler port to maintain a constant oil level. Wherein the cartridge tank is mounted on an upper end flange portion of a filter tube, and a support leg is provided at a bottom portion of the filter tube to reach an inner bottom surface of the auxiliary tank. Than it is.

[0005]

When the full-filled cartridge tank 10 is placed on the auxiliary tank 1, the filler port 11 of the cartridge tank 10 is inserted into the filter tube 4 mounted in the auxiliary tank 1 and protrudes inward. The valve device 12 is opened by the valve rod 7, and fuel oil is supplied through the filter cylinder 4. The oil level in the auxiliary tank 1 is held constant at the valve valve 12 opened position by the valve rod 7, (Not shown).

When the cartridge tank 10 is mounted on the auxiliary tank 10, the cartridge tank 10 is mounted on the upper end flange 5 of the filter tube 4, and the bottom of the filter tube 4 is attached to the inner bottom surface of the auxiliary tank 1. Since the supporting legs 13 are provided, the cartridge tank 1
Zero weight is supported by this filter tube 4 and the auxiliary tank 1
It does not act on the upper surface, and furthermore, the filter cylinder 4 is a cylindrical body and does not have to worry about being strongly deformed by a vertical force.

Therefore, even if a large-capacity and heavy cartridge tank 10 is used, the auxiliary tank 1 is reliably prevented from being damaged or depressed, and there is no fear of oil leakage or abnormal combustion, so that the auxiliary tank 1 can always be used with peace of mind.

If the filter tube 4 is made of a synthetic resin and the support legs 13 are integrally formed, the filter tube 4 can be formed extremely easily and can be provided at low cost without the need for separate parts.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an oil burning appliance according to the present invention. Reference numeral 1 denotes an auxiliary tank made of sheet metal having an opening 2 formed on the upper surface. The auxiliary tank 1 always holds a fixed amount of fuel oil, and supplies the fuel oil to a vaporizing type combustion unit via an electromagnetic pump 3 to burn it.

Reference numeral 4 denotes a filter tube which is detachably mounted in the opening 2 and is formed of a synthetic resin in a cylindrical shape and has an upper end flange portion 5 which extends outward and is located on the upper surface of the auxiliary tank 1.
In addition, a plurality of ventilation holes 6 are formed in an upper part located in the auxiliary tank 1 to communicate the atmosphere with the inside of the filter tube 4 and the inside of the auxiliary tank 1.

Further, a valve rod 7 protruding upward is provided at the inner bottom of the filter tube 4, and a plurality of outlets 8 are formed in a lower peripheral wall of the filter tube 4, and a fine mesh net is formed on the outer periphery thereof. A filter 9 for removing dust in fuel oil is provided.

A fuel tank 10 is mounted on the auxiliary tank 1 with the fuel supply port 11 down and supplies fuel to the auxiliary tank 1 by a fixed amount by using a natural head. By inserting the filler port 11 into the filter cylinder 4, the valve device 12 in the filler port 11 is pushed up by the valve rod 7 to supply fuel oil, and the pushed-up position becomes a constant oil level A.

Reference numeral 13 denotes a plurality of support legs integrally formed at the bottom of the filter tube 4, the lower end of which extends up to the inner bottom surface of the auxiliary tank 1 and is provided upright in the auxiliary tank 1. By mounting the cartridge tank 10 on the upper end flange 5, the cartridge tank 10
Is supported by the filter tube 4.

Next, the operation of the embodiment of the present invention will be described. When the currently full cartridge tank 10 is mounted on the auxiliary tank 1, the valve device 12 in the fuel supply port 11 is opened by the valve rod 7, and the fuel oil in the cartridge tank 10 is supplied to the auxiliary tank 1. If the fuel oil is supplied to the combustion unit via the electromagnetic pump 3, the fuel oil is consumed sequentially.

On the other hand, even when the cartridge tank 10 is mounted violently, the cartridge tank 10 is mounted on the upper end flange portion 5 of the filter tube 4 as shown in FIG. Is formed and reaches the inner bottom surface of the auxiliary tank 1, and the auxiliary tank 1 is usually mounted directly on a base plate (not shown). And has no influence on the auxiliary tank 1.

Therefore, even if the cartridge tank 10 which has become heavy due to the increased capacity is dropped onto the auxiliary tank 1, there is no fear of the auxiliary tank 1 being damaged or collapsed, and oil leakage and abnormal combustion can be reliably prevented. Can be prevented,
It is always safe to use.

[0017]

In summary, the present invention has an auxiliary tank for supplying fuel oil to a combustion section while receiving fuel oil and holding the fuel oil at a constant oil level, and is detachably attached to an opening provided on the upper surface of the auxiliary tank. A filter cylinder and a cartridge tank inserted into the filter cylinder with an oil supply port and placed on the upper surface of the auxiliary tank.The filter cylinder is erected from the bottom and pushes up a valve device of the oil supply port to raise a constant oil level. The cartridge tank is provided on the upper end flange portion of the filter cylinder, with a valve rod for holding the filter and a filter for removing dust in fuel supplied from the cartridge tank into the auxiliary tank on the peripheral wall. The cartridge tank is mounted on the bottom of the filter cylinder and has support legs that reach the bottom of the auxiliary tank. The oil tank can be supported by the filter cylinder and the capacity increases.The oil tank leaks due to the damage of the auxiliary tank caused by roughly handling the heavier cartridge tank and the constant oil level fluctuation due to the depression of the upper surface of the auxiliary tank. It can reliably prevent abnormal combustion of the cause, can be used at all times with peace of mind, and can be used easily without requiring careful handling.
