Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a portable water heater that can be used for cooking during outdoor activities. It is related to.

0002

[Conventional technology]

Traditionally, when heating liquids for cooking or drinking purposes during outdoor activities, etc. A ner-type combustor was used to heat liquid placed in a pot or kochel. The flame As a fuel, gas filled in a cartridge and volatile liquids such as kerosene and gasoline can be used. It used fuel.

0003

[Problem that the invention attempts to solve]

Conventional burner type combustors have strong firepower and long combustion time, but the weight and volume of the device is Because it is bulky, it can become a burden when carrying out small activities with light equipment. Also, the combustor In addition to the main unit, fuel carriers and heating containers such as pans are also required, which further reduces the burden of carrying the device. This increases the workload and makes it difficult to package luggage. In addition, care must be taken when handling volatile and flammable fuels, and Creating and handling requires some skill. The purpose of this invention is to solve the problems mentioned above. Sunahachi, (b) It should be lightweight and compact enough to be portable and not burdensome even when carried by an individual. ．． (b) Directly pour the liquid in a cup or tableware without the need for a heating container such as a pan. It can be heated. Furthermore, these cups and tableware are made of heat-resistant materials such as paper or styrofoam. Even those of inferior quality are acceptable.

0004

[Means to solve the problem]

According to the present invention, the above purpose is achieved by the following structure. Sunahachi, A heat pipe (2) for heat transfer is fixed by penetrating a flat plate (1) made of flame-retardant insulation material. A recess for placing the solid fuel (5) on the flat plate (1) next to this heat pipe (2) (3) and further surrounds this heat pipe (2) and recess (3). , a portable device characterized in that the windshield cover (4) is attached on the flat plate (1). A simple band-type water heater.

[0005]

[Effect]

Heating the heat pipe (2) with the combustion heat of the solid fuel (5) on the flat plate (1) According to its function, the heat pipe (2) instantly transports heat to the low temperature area. In other words, the heat is radiated in the heated liquid (6). The flat plate (1) in contact with the heat pipe (2) has heat insulating properties, so the heat pipe There is almost no heat conduction from (2) to the flat plate (1), and the heat pipe (2) receives the heat. Heat is transported to the heated liquid (6), which is the low temperature part, with minimal loss. When the product of this invention is placed on a container (7) containing a liquid to be heated (6), a flat plate ( 1) becomes the lid of the container (7), and at the same time, a part of the heat pipe (2) is heated with the liquid to be heated. automatically placed in the body (6). Therefore, the heat pipe (2) releases The generated heat directly and efficiently heats the liquid to be heated (6). Furthermore, since the flat plate (1) acts as a lid to seal the container (7), efficiency within the closed system is improved. At the same time, since the flat plate (1) in contact with the container (7) has heat insulating properties, , there is no heat loss due to heat transfer from the container (7). In other words, the heat mass (thermal inertia capacity) and heat loss as a heat transfer system are extremely small. Sai. As mentioned above, in this configuration, the combustion heat received by the heat pipe (2) is immediately lost without any loss. This can be converted into the work of heating the liquid to be heated (6). Also, it is mounted on the flat plate (1) in a manner that surrounds the solid fuel (5) and the heat pipe (2). The girder wall-like wind cover (4) prevents the flame from being disturbed by the wind and the heat caused by the wind. Wind prevention function to prevent temperature drop of pipe (2), solid fuel (5) and heat pump Type (2) has an enclosure function to keep the ambient temperature high and a It also has the function of reflecting the comb inward.

[0006]

【Example】

A preferred embodiment of the present invention will be explained below with reference to the figures. The flat plate (1) has a lid function for the container (7) and a function to hold the solid fuel (5). Although it is desirable that the surface be smooth, it should be partially recessed in order to stably hold the solid fuel (5). Let (3). This depression (3) is where ash and wax are scattered after the solid fuel (5) is burned. There is also a role to make sure that it does not occur. The heat pipe (2) is partially installed near the combustion flame of the solid fuel (5). Attach it to the flat plate (1). At this time, the upper part of the heat pipe (2) is You can also fold it to expand it. Furthermore, in order to prevent the heat pipe (2) from burning due to direct combustion flame, A part of the heat pipe (2) may be coated with a metal or the like with good thermal conductivity. Also, The part of the heat pipe (2) that enters the heated liquid (6) is also equipped with a You may also attach a heat sink or fin. However, the heat pipe (2) is from It must have enough capacity to be cooked without being damaged. The heat pipe (2) can be fixed to the flat plate (1) by simple fitting, screwing or bonding. You may be forced to wear them individually by wearing them, welding them, caulking them, etc., but if you prioritize portability, A snap-in type or screw-on type that can be disassembled and assembled as needed is preferable. The windshield cover (4) is high enough to hide the solid fuel (5) and heat pipe (2). , with one or more openings above or on the sides to ensure ventilation. Flat plate (1 ) can be fixed to a flat plate (1 ) It is desirable to select a method that is easy to attach and remove. In addition, in order to further improve portability, the windshield cover (4) is omitted and the side part of the container is There is also an example of installation as shown in Figure 5.

[0007]

[Effect of the idea]

As is clear from the above explanation, the following effects can be obtained using the present invention. (b) It is lightweight and has a minimal shape, so it is not a burden to carry. Also, disassembly/assembly It is also easy. (b) The operation is as simple as placing the solid fuel (5) in the recess (3) and igniting it. Unlike other combustion equipment, it does not require skilled operation, and since it uses solid fuel, it is easy to transport. It is also safe during preparation and operation. (c) For heating liquids, there is no need for a pan or cooker, and it is possible to directly heat a cup or tableware. It can be attached to a container to directly heat the liquid inside. (d) The part that comes into contact with the container is an insulating material, so use heat-resistant materials such as paper or styrofoam. It can also be used in low containers. In other words, it can be used for both paper cups and instant noodles in containers. This is possible. (e) Even if solid fuel is not available, candles, lighters, etc. can be used as alternative heat sources. ．． Conversely, it is also possible to directly cool a liquid by using a coolant. (F) Since there are no mechanical or electrically moving parts, the probability of failure is extremely low. Also, Heat pipes are maintenance-free and can be used semi-permanently, so they are suitable for this study. The lifespan of the product is also semi-permanent.
