Description

Detailed Description of the Invention "Field of Industrial Application" The present invention comprises a burner, a combustion chamber in which the burner is arranged, a transfer duct for transferring combustion gas, an outlet duct, and a combustion chamber heated by the heat generated by the burner. The present invention relates to a stove consisting of at least one heating unit, which is primarily adapted to be used for cooking food, and a lid forming a duct for conducting heated air.

More specifically, the present invention relates to a stove that uses liquid or gaseous fuel and is adapted to be used in a leisure vehicle such as a boat, a trailer for a camp house, or the like.

``Conventional technology'' Most stoves used in boats, camp trailers, etc. are open type stoves, which means that the flame is exposed and the combustion gases remain inside the room. . The fuels used are relatively pure fuels such as liquefied natural gas, alcohol, or oil-based fuels. In an open oven, burning fuel produces carbon dioxide and water vapor. Like cooking stoves, heating stoves used in boats and camp trailers are of open construction and are configured to use the fuels listed above.

There are several problems with stoves that expose the flame. Since the combustion gas remains indoors, the humidity of the indoor air increases due to the water vapor contained in the combustion gas.
Furthermore, as the room fills with combustion gases, ventilation becomes necessary because oxygen is consumed during the combustion process and because smoke and soot appear in the combustion gases and carbon dioxide. . Additionally, stoves with exposed flames can be dangerous in poorly ventilated rooms. This is because such poorly ventilated rooms reduce oxygen content and increase carbon dioxide, resulting in incomplete combustion and the production of dangerous carbon monoxide. Because of the increased humidity and the risk of carbon monoxide formation, it is not advisable to use stoves with exposed flames for long periods of time.

``Problems to be Solved by the Invention'' The object of the present invention is to provide a stove that can eliminate the above-mentioned drawbacks, and is particularly suitable for use in boats, camp/house trailers, etc. To provide a stove that is safe and does not raise the humidity or carbon dioxide content of indoor air.

Another object of the invention is to provide a stove suitable for food cooking and heating purposes.

"Means for Solving the Problems" The gist of the present invention is to provide a burner, a combustion chamber in which the burner is arranged, a heating chamber, and a heating plate on the upper part of the heating plate, a heating unit into which the combustion gas emitted from the heating chamber enters; a duct for discharging the combustion gas emitted from the heating chamber of the heating unit into the atmosphere without leaking; and a lid configured to be placed over the heating plate. and a heated air duct formed between the inner surface of the lid and the heat conductive surface of the heating plate, and a heated air blower that blows air into the heated air duct.

"Function" The stove according to the present invention is configured so that the combustion gas emitted from the combustion chamber is guided into the atmosphere through the combustion gas transfer duct and the outlet duct, which are designed to prevent leakage. There is no risk that the generated water vapor, carbon dioxide, smoke, soot, carbon monoxide, etc. will enter the indoor space, so the content of water vapor and/or carbon dioxide in the indoor air will not increase, and the smoke There is no increase in carbon monoxide content.

You can also remove the lid and use the heat-conducting surface of the heating plate to cook food.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The stove shown in the accompanying drawings comprises the following components, which are constructed in such a way that combustion gases do not escape: a combustion chamber 2 with a burner 1, a combustion gas transfer duct 3, a combustion gas outlet duct 4; It consists of two heating units 5 and 5'. In the illustrated embodiment, the heating units 5, 5' each consist of a heating plate 5a, 5a' and a heating chamber 5b, 5b' provided below the heating plate 5a, 5a'. a combustion chamber 2; a first heating plate 5a disposed above the combustion chamber 2;
a heating chamber 5b located below, and a transfer duct 3 for transporting combustion gases from the heating chamber 5b to a second heating chamber 5b' provided below the second heating plate 5a'; The combustion gas outlet duct 4 for discharging combustion gas from the heating chamber 5b' of the second heating plate 5a' to the atmosphere 6 is assembled in such a manner that the entire structure does not leak gas when combined. The combustion chamber 2 has a first heating plate 5a' so that a part of the heat generated in the combustion chamber 2 is transmitted to the first heating chamber 5a' and a part is transmitted to the second heating plate 5a' together with the combustion gas. It is arranged at the lower position of the heating plate 5a. The stove according to this embodiment further includes:
A combustion air blower 8 for guiding combustion chamber air to the combustion chamber 2 through a duct 7 and a member 9 for guiding fuel to the burner 1 are provided.

The stove shown in the accompanying drawings further comprises a lid 10 forming a jacket surface. Since the lid 10 is attached so as to cover both the heating plates 5a and 5a', a duct 11 is formed between the inner surface of the lid 10 and the heat conductive surfaces of the heating plates 5a and 5a' to guide high-temperature air. Ru.
Furthermore, the stove according to the present embodiment has a heated air blower 1 that sends air into the duct 11 through the inlet 12, and also blows air from the duct 11 into the indoor space 13 through the outlet 11a.
It is equipped with 4. The air passing through the heated air duct 11 is warmed by the heat conducting surfaces of the heating plates 5a, 5a'. Also, when the blower 14 is stopped and the lid 10 is removed, the heating plate 5
Since a, 5a' is exposed, its heat conducting surface can be used to cook food. As above,
The stove according to the invention has two functions. This means that the stove according to the invention can be used primarily for heating purposes.
In this case, a lid 10 is placed over the heating plates 5a, 5a', and a blower 14 blows air into a heated air duct 11, warming the air while it passes through the duct 11. Furthermore, once the blower 14 is stopped and the lid 10 is removed, the heating plates 5a, 5a' are exposed, so that food can be cooked using the heat conductive surfaces of the heating plates.

When using the stove shown in the attached drawing, a combustion air blower 8 blows combustion air into the combustion chamber 2.
Similarly, a member 9 guides fuel such as kerosene or butane to the burner 1. The burner 1 is ignited by an electric igniter. Combustion gas generated during the combustion process is guided from the combustion chamber 2 to the combustion gas transfer duct 3 via the heating chamber 5b. The heat of the combustion gases is transferred to the first heating plate 5a via the heat-conducting ribs or surfaces. Further, the combustion gas discharged from the heating chamber 5b is conveyed through the combustion gas transfer duct 3 to the heating chamber 5b' of the second heating plate 5a'.
The second heating plate 5a' has heat conducting ribs and/or
or heated by heat transferred from the combustion gases to the heating plate through a heat-conducting surface. Furthermore, the combustion gases flow from the heating chamber 5b' of the second heating plate 5a' into the outlet duct 4 and are further discharged into the atmosphere 6. When used for heating, the heating plates 5a, 5a' are heated by the heat of the combustion gas, and the duct 11 is heated by the heat of the heat conduction surface.
This heats the air flowing through the interior of the vehicle and directs it to indoor spaces such as boats, camp/house trailers, tents, and living rooms.

"Effects of the Invention" Since the present invention has the above-described structure and operation, it is possible to reduce the amount of water vapor, carbon dioxide, smoke, and soot generated during combustion.
There is no possibility that carbon monoxide or the like will enter the indoor space, so the content of water vapor and/or carbon dioxide in the room will not increase, and the content of smoke or carbon monoxide will not increase. and again,
It can be used not only for heating, but also for cooking food.
