Abstract

PURPOSE:To enhance safety performance by allowing both end opening sections of a communication pipe to be positioned at the ends on the opposite side in a plurality of oil receiving pans respectively and boring openings at an elevation below steady oil level of the oil receiving pans and moreover boring upward openings. CONSTITUTION:When an oil heater is slantingly installed with the right side raised at an inclination angle of about ten degrees, one end opening section 13A of a communication pipe 13 positioned at the right end in a right sided oil receiving pan 7 rises at an elevation higher than an oil level, thereby preventing the oil in the right sided oil receiving pan 7 from flowing into a left sided oil receiving pan 9 by way of a communication pipe 13. Likewise, when the oil fan heater is slanting installed with the left side raised, the opening section 13B on the other end of the communication pipe 13 positioned on the left end in the left sided oil receiving pan 9 exceeds the oil level, thereby preventing the oil in the left sided oil receiving pan 9 from flowing out into the right sided oil receiving pan 7 by way of the communication pipe 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to liquid fuel combustion devices such as oil fan heaters and oil stoves.

(b) Conventional technology In this type of liquid fuel combustion device, a predetermined amount of oil is supplied from the oil supply tank to the oil pan. By supplying oil to a combustion part such as a burner using a fuel pump such as a magnetic pump, combustion is performed in the combustion part. However, since the capacity of the refueling tank (3 to 5 N) was small, it was necessary to refuel frequently. Therefore, in the method disclosed in Japanese Utility Model Publication No. 46-5412, a fuel tank and an oil pan are provided on the left and right sides of the combustion section, and the heights of the oil outlet of the left and right fuel tanks are set to be different. Even if one fuel tank becomes empty, fuel can be filled from the other tank and combustion can continue.

(8) Problems to be Solved by the Invention This type of liquid fuel combustion device has the advantage of being able to sustain combustion for a longer period of time compared to a device with a single fuel tank and oil pan, and reducing the hassle of refueling. be. However, since the left and right oil pans communicate through the combustion part, if the combustion device is installed at an angle, there is a risk that the oil in one oil pan will move to the other oil pan, causing an oil leak. there were.

Therefore, in recent years, a safe liquid fuel combustion device has been developed that does not cause oil leakage even when the combustion device is installed at an angle (inclination angle of 10 degrees or less). This combustion device is shown in Figure 4. When one oil supply tank (a) becomes empty and the oil in one oil pan (b) decreases, the oil transfer pump (c) is activated, The oil replenished from the oil supply tank (d) to the other oil pan (ne) is transferred to one oil pan (b).
The transferred oil is then transferred to the fuel pump (
It is designed to be supplied to the combustion section (g) by the Only when the oil level in one oil pan (b) decreases, the oil can be moved from the other oil pan (wood) to one oil pan (b).
Even if the combustion equipment is installed tilted, the oil in the other oil pan (*) will be transferred to the one oil pan (b).
There is no risk of oil leakage as it will not flow out.

By the way, the conventional liquid fuel combustion apparatus shown in FIG. 4 requires a pump for transferring oil in addition to a fuel pump for supplying oil to the combustion section, which has the drawback of significantly increasing costs.

The present invention was developed in view of the above-mentioned circumstances, and aims to reduce the troublesomeness of refueling, prevent oil leakage due to movement of oil between a plurality of oil pans, and simplify the configuration. The purpose is to

(d) Means for Solving the Problems The present invention includes a combustion section such as a burner, a fuel pump that supplies oil to the combustion section, a plurality of oil pans that store oil pumped by the fuel pump, and It includes a plurality of oil supply tanks that replenish oil to the oil pans, and a communication pipe that communicates the plurality of oil pans, and the openings at both ends of the communication pipe are connected to the opposite end of the plurality of oil pans. located respectively in
The opening is below the steady oil level of the oil pan and opens upward.

(*) Effect With this configuration, the multiple oil pans are connected to each other by the communication pipe, so oil will continue to be supplied to the combustion section until the multiple oil tanks are empty, and this will result in a long period of time. Combustion can be continued, and there is no need to refuel frequently. In addition, since the openings at both ends of the communication pipe are located at opposite ends of the plurality of oil pans, and open upward and below the steady oil level of the oil pans, the combustion equipment If it is installed at an angle, the opening at one end of the communication pipe will open above the oil level of one oil pan, so the oil in one oil pan cannot be transferred to the other oil pan. There is no need to worry about oil leakage, and there is no need for a pump to transfer oil from one oil pan to the other, which simplifies the configuration and increases safety while significantly increasing costs. can be suppressed.

Example) An example in which the present invention is applied to a kerosene fan heater will be described below with reference to FIGS. 1 to 3.

In Figures 1 to 3, (1) is an exterior case that has a horizontally elongated hot air outlet (2) in the center of the front, and inside this exterior case (1) are a burner fan (3) and a burner fan (3). A vaporizing burner (4) to which combustion air is supplied from a fan (3), a combustion tube (5) with an open top connected to the burner (4), and a blower facing the combustion tube (5). The air flowing in from the guide device (6) and the air suction port (not shown) provided at the center of the back of the outer case (1) is guided to the blower guide device <6), and the air is blown from the combustion tube (5). A blower fan (
A right oil pan (7) and a right oil tank (8), and a left oil pan (9) and a left oil tank (10) are provided on both left and right sides of the oil tank (not shown). ing.

The height of the oil outlet (8A) of the right refueling tank 8) is approximately 5 to 50 cm higher than the oil outlet (IOA) of the left refueling tank (1o).
Bmm is set high.

In addition, a fuel pump (12) such as a magnetic pump is arranged in the right oil pan (7) to supply oil (kerosene) from the right oil pan (7) to the burner (4) via an oil pipe (11). Furthermore, a hollow vibe-shaped communication pipe (13) is provided between the inner oil pans (7) and (8) to communicate them.As shown in FIG. Openings at both ends (13
A) and (13B) are extended to mutually opposite end positions in the inner oil pans (7) and (9), respectively, and the steady oil level (Ll) (L2) of both oil pans (7) and (9) is It is located at a lower position than the above, and is opened upward by bending. In addition, (14) is a residual oil switch that senses the weight of the right fuel tank (8), and this residual oil switch (14)
is activated to activate an alarm (not shown) when the right fuel tank (8) is empty.

In the above configuration, when the operation starts, the vaporization heater (
(not shown) heats the carburetor of the burner (4), and when the carburetor is sufficiently heated, the burner fan (3) and fuel pump (12) are driven, the igniter is activated, and the burner (
4) starts combustion. At this time, the fuel pump (12) pumps up the oil from the right oil pan (7) and transfers the oil to the oil pipe (11).
) to the vaporizer of the burner (4). The combustion gas from the burner (4) rises inside the combustion tube (5) and flows out into the blower guide device (6), where it mixes with the wind from the blower fan (not shown) and becomes warm air. , warm air outlet (
2) is discharged into the room for heating.

Now, when the oil in the right fuel tank (8) is consumed and becomes empty, the remaining oil switch (14) is activated and the alarm goes off to the right fuel tank (8).
8〉 empty capacity is notified, and the fuel pump (13) moves to the left oil pan (
9) through the communication pipe (13) into the right oil pan (7) and continues to supply it to the vaporizer of the burner (4). In this way, combustion continues until the right fuel tank (8) and the left fuel tank (10) are emptied of oil.

Next, as shown in Fig. 3, when this oil fan heater is installed with an inclination angle of approximately 1o upward to the right, the communication pipe (13) located at the right end in the right oil pan (7) ) is above the oil level, and the right oil pan (13A) is above the oil level.
7) The oil will not flow out to the left oil pan (9) through the communication pipe (13), and if the kerosene fan heater is completely installed tilted upward to the left, contrary to the tilted state described above, the left Since the other end opening (13B) of the communication pipe (13) located at the left end in the oil pan (9) is above the oil level, the oil in the left oil pan (9) flows through the communication pipe (13). There is no possibility that the oil will pass through and flow out to the right oil pan (7).

According to this embodiment, as long as there is oil in the right oil tank (8), the oil that has been refilled from the right oil tank (8) to the right oil pan (7) is pumped up to the fuel pump (12) and the burner ( 4
) is completely supplied and the right oil tank (8) is empty, the oil replenished from the left oil tank (10) to the left oil pan (9) passes through the communication pipe (13) to the right oil pan (7>). This oil flows into the burner (4), so both oil tanks (
8) Combustion can be continued until the fuel in (10) is empty, eliminating the trouble of frequent refueling and providing excellent usability.

In addition, a communication pipe (13) that connects both base saucers (7) and (9)
The openings at both ends (13A>(13B) of the oil pan (7) (
9) to opposite end positions in the oil pan (7>(9)).
Since the opening is below L2) and upward, if the kerosene fan heater is installed at an angle, one opening (13A) or (13B) of the communication pipe <13) Since the oil level is above the oil level in the oil pan, there is no risk of oil leaking from one oil pan to the other oil pan, resulting in excellent safety. Moreover, unlike the conventional system, there is no need for a pump to transfer oil from one oil pan to the other oil pan, so the configuration can be simplified, and a significant increase in cost can be suppressed while improving safety.

(G) Effects of the Invention Since the present invention is configured as described above, combustion can be continued until a plurality of fuel tanks are empty.
Not only does it require less frequent oiling, which improves usability, but even if the device is installed at an angle, it prevents oil from moving from one oil pan to the other, eliminating concerns about oil leaks. Therefore, safety can be improved, the configuration can be simplified, and an inexpensive and highly safe combustion device can be provided.
