Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil supply device for supplying liquid fuel to an indoor heater using liquid fuel such as petroleum, such as a fan heater or a supply / exhaust type hot air heater.

[0002]

2. Description of the Related Art A conventional oil feeder is provided with a fuel tank for supplying fuel by a natural fall from a cartridge tank incorporated in a heater or a fuel tank installed outdoors to a combustor in the heater. Is maintained at a constant height, for example, about 17 to 25 cm, higher than that of the combustor, so that a head can be obtained. There is also a separate tank type oil feeder that separates the liquid fuel tank from the heater and installs only the liquid fuel tank indoors or outdoors and supplies liquid fuel from such a tank to the combustor. Such a separate tank type oil feeder has a capacity of 25 to 40 liters even if it is an indoor type,
A heater and a fuel tank were installed, and they were used on the assumption that they would hardly move once they were connected by an oil supply pipe.

[0003]

However, in a heater having a structure in which an oil supply device is built in the inside of the heater as described above, a tank in the heater is required to keep the level of the oil supply device at a certain level or higher. It is necessary to form a corresponding space below, and to secure a storage space for the liquid fuel tank in the heater, and therefore, the shape of the entire heater is not only the minimum size required for the heating function, It had to be a large aircraft heater with a refueling tank and associated space. In such a heater, when the refueling tank is empty, the tank is taken out of the heater, refueled, and re-supplied such that the fuel is stored in the heater again. In addition, the work had to be performed at a high position of the heater, and it was a rather laborious work, and the area around the heater could be contaminated with oil and the back could be hurt.

[0004] In addition, regardless of whether the separate tank type oil feeder is of an indoor type or an outdoor type, a large installation floor is required to stably mount the tank at a height at which the tank can be refueled by forming a head drop. After installing the tank, it was difficult to move the heater because it was necessary to attach the legs that occupied the surface, and after the installation, the heater and the fuel tank were connected by an oil supply pipe. . For this reason, the separate tank-type heater could hardly be used to move the heater for local heating or heating in another room.

[0005] As a countermeasure for this, there has been proposed a structure in which a liquid fuel supply device for a heater is forcibly supplied by using a pump, but the structure is complicated and lacks convenience. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has the advantage of simplifying the refueling and reducing the installation space and reducing the installation space without refueling. It is an object of the present invention to provide an oil feeder with improved ease of installation.

[0007]

According to the first aspect of the present invention,
In a device for supplying a liquid fuel such as petroleum to a heater, the device has a storage tank and an oil supply pump for supplying liquid fuel in the oil tank to the storage tank, and the storage tank has a built-in heater. A liquid level sensor serving as a signal source for starting and stopping the oil supply pump is provided so that an oil level equal to or higher than a predetermined head is secured for the burned combustor, and a suction side of the oil supply pump is provided on the suction side of the oil supply pump. This is an oil feeder in which an oil feed pipe for pumping fuel is detachably provided.

[0008] The invention according to claim 2 is a storage tank mounted at a position such that an oil level above a predetermined drop is secured to a combustor built in a heater, and a liquid fuel in the oil tank. Unit having an oil supply pump for supplying oil to the heater through the storage tank, a detachable oil supply pipe for supplying fuel from the oil tank to the oil supply unit, a base for supporting the oil tank, and a cover for the oil tank And an oil feeder comprising:

According to a third aspect of the present invention, there is provided a storage tank for supplying a liquid fuel such as petroleum to a heater using a head, and a refueling pump for supplying liquid fuel in the oil tank to the storage tank. The storage tank has a liquid level sensor that sends a signal for controlling an oil pump so that an oil level above a predetermined drop is secured to a combustor built in the heater, and a feeder with a cock connected to the heater side. An oil port is provided, and an oil supply pipe for pumping fuel from an oil tank is detachably provided on the suction side of the oil supply pump, and the storage tank supports the oil tank adjacent thereto. This is an oil feeder having a shallow base and a cover for covering an oil tank placed on the base.

According to the present invention, an apparatus for supplying a liquid fuel such as petroleum to a heater has a storage tank and an oil supply pump for supplying liquid fuel in the oil tank to the storage tank. To control the start and stop of the refueling pump so that the oil level of a certain drop or more is secured for the built-in combustor, and to pump the fuel from the oil tank to the suction side of the refueling pump The oil supply pipe is provided detachably, so the storage tank is installed in a small installation space, and the liquid fuel is supplied to the storage tank directly from the oil tank via the oil supply pipe. This makes it possible to perform refueling by natural fall without much labor and labor.

Further, the oil supply device of the present invention has a storage tank and an oil tank for temporarily storing liquid fuel such that an oil level above a predetermined head is secured for a combustor built in a heater. Refueling unit having a refueling pump for supplying the liquid fuel to the heater through the storage tank, a detachable oil supply pipe for supplying fuel of the oil tank to the refueling unit, and supporting the oil tank adjacent to the storage tank Since it has a base and a cover that covers the oil tank placed on this base, the storage tank and refueling pump are installed collectively in a small installation space. Done directly from the oil tank through a pipe,
In addition, the oil tank can be supplied to the heater simply by placing it on the base adjacent to the storage tank and inserting the oil supply pipe and connecting it to the suction side of the pump. Thus, the liquid fuel can be easily supplied.

Further, if the base constituting the oil feeder is made shallow and the cover for covering the oil tank is provided as in the oil feeder of the present invention, the oil tank can be replaced and the oil feed pipe can be attached and detached. Sometimes, even if fuel spills, it will remain in the base and will not directly stain the floor, and the cover prevents the oil tank from being exposed. Even if placed in a room, the appearance is rarely impaired.
