Description

[Detailed description of the invention] This invention relates to an improvement of the wrapping bag of the combustion wick for oil combustion equipment.In other words, it is conventional to conduct combustion tests on oil combustion equipment with a combustion wick pre-installed on a factory assembly line. Only those that pass the test are packed and shipped after removing the fuel from the fire pan and fuel tank.

By the way, when a user uses a new oil combustion device incorporating this combustion wick, it can produce 100% of the predetermined calorific value (fuel absorption amount) without any problems.

However, when storing an oil combustion device for a long period of time, or when providing refills for sale, the combustion wick is sometimes packaged and stored separately without being incorporated into the combustion device.

At this time, the combustion wick 1' was sealed in a wrapping bag 2' such as a cellophane bag or a plastic bag and sealed with staples or adhesive 3', but it was removed from the stored wrapping bag 2'. When the combustion wick 1' was incorporated into the fire pan of an oil combustion device and burned, approximately 70% of the oil combustion devices did not produce the specified calorific value (fuel absorption amount), resulting in a problem of weak thermal power. .

Therefore, considering that the cause of this is in the combustion wick 1', we compare the weight of the combustion wick 1' before being sealed in the packaging bag 2' and the weight of the combustion wick 1' opened after being sealed in the packaging bag 2'. It became clear that the opened combustion wick 1' was several grams heavier, and this was because the combustion wick 1' had been stored in a poorly sealed bag 2', and had absorbed moisture and moisture from the air. The water content increases, and as a result, when the combustion wick 1' is installed in an oil combustion device, the water content inside the combustion wick 1' inhibits the suction of fuel, making it impossible to generate the specified amount of heat as shown by line B in Figure 1. Ta.

However, even if the combustion wick does not produce 100% of the specified calorific value, it is sufficient to dry it thoroughly after opening the bag, and if it is used without obtaining the specified calorific value, the water content will gradually evaporate. However, when new, the predetermined calorific value was not achieved, which was a major problem for users.

This idea focuses on this point, and by enclosing the combustion wick for oil combustion equipment in a bag that creates a vacuum, moisture and moisture in the air are removed when the combustion wick is stored. This prevents suction and allows the combustion wick to generate a predetermined amount of heat when installed in an oil combustion device.

Next, one embodiment shown in the drawings will be explained.
Basically, it is the same as the conventional example shown in Fig. 2, but numeral 1 is a cylindrical combustion wick, and the combustion wick 1 is flat and wrapped in a non-porous material such as polyethylene or thick vinyl. Enclose it in a bag 2 and seal it with a seal 3.

More specifically, the substrate 4 constituting the wrapping bag 2
Initially, the combustion wick 1 is placed on top, and then covered with a transparent plate 5, while the outer periphery of the substrate 4 is pressed and sealed 3 with the outer periphery of the transparent plate 5, and a means for removing the air inside (not shown) is used. The combustion wick 1 is removed by vacuum sealing, creating a vacuum inside the combustion wick 1.

When the combustion wick 1 of the wrapping bag 2 constructed in this manner is incorporated into an oil combustion device, it forms a curve as shown by line A in FIG. 1, and can generate a predetermined amount of heat.

The reason for this is that even if the external environment of the packaging bag 2 changes in temperature and humidity due to the vacuum inside the packaging bag 2, the combustion wick 1 does not change accordingly.
This is because it prevents moisture and water from being sucked in from the air.

As described above, in this invention, when a combustion wick for an oil combustion device is enclosed in a packaging bag, the combustion wick is enclosed in a vacuum bag, so the oil combustion device and the combustion wick are packaged separately. The combustion wick does not absorb moisture or moisture from the air during storage, and the combustion wick does not absorb moisture or moisture in the air, so it can sufficiently generate a predetermined amount of heat.
