Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The detailed description of the technical structures in the same or similar categories will be omitted. .

The present invention relates to a heating device for receiving a heating member, which does not require a separate power source such as a super, solid fuel, or a gas burner, inside the heating member to transfer heat to an object by convection action of air, To a chair for outdoor use which allows heat to be transmitted to the body of a user who is sitting.

The configuration of the present invention for this purpose includes a main body 10, a ventilation part 20, a mounting part 30 and an opening part 40, as shown in Figs. 1 to 7.

As shown in Figs. 1 to 6, the main body 10 of the present invention having such a structure is a circular or polygonal pipe shape and forms an outer shape of a warming device using a non-power source. The heating member F is mounted and accommodated in the housing space 11 from the upper side of the main body 10, .

This housing space 11 also provides a convection space for air heated by the combustion of the heat generating member F as well as the housing of the heat generating member F, It may be made of stainless steel, iron, an alloy, a heat-resistant plastic, or the like, and may be made of a synthetic resin or a metal material having a nonflammable or heat-resistant property.

The main body 10 is relatively compact in size, and it is preferable that it can be easily carried in a miniaturized heating device due to the necessity of mounting in an outdoor chair described later. For example, the main body 10 has a diameter 5 cm and a height of 10 cm.

In addition, in the present invention, the heating member F mounted in the accommodation space 11 may be a super, solid fuel or gas burner that does not require a separate power source. And can be mounted inside the main body 10 in a wrapped state.

The metal foil M may be an aluminum foil, an aluminum foil, a copper alloy foil or a stainless steel foil. Preferably, the metal foil M is made of a nonflammable material so as not to be burned by heat or heat generated by combustion of the heat generating member F.

The heating member F is wrapped with the metal foil M or the incombustible material and mounted in the accommodation space 11 so that the wax generated due to the burning of the candle can be prevented from flowing out of the metal foil M, Even if the height of the candle is lowered by the combustion in the process, since the height variation of the metal foil M does not occur, the flow-out blocking effect of the above-described candle can be firmly maintained.

When the heat generating member F is installed in the inner receiving space 11 of the main body 10, the height of the heat generating member F is different from the height of the main body 10, so that a minimum air convection space and a combustion section can be ensured The height of the heat generating member F is made lower than the height of the main body 10 so that the occurrence of soot due to the irregular combustion of the heat generating member F can be suppressed, When the height is 10 cm, the height of the heat generating member F may be 6 cm or less so as to have a height difference of 4 cm or more.

1 and 2, the main body 10 has one or more observation portions 12 along its periphery, through which the accommodation space 11 inside the main body 10 can be observed from the outside , It is possible to easily determine the replacement point of the heating member F by observing the degree of combustion of the heating member F or the degree of exhaustion of the fuel outside the main body 10. [

As shown in FIG. 2A, such an observation section 12 may be a long and openly-formed long hole, so that the observation of the accommodation space 11 as well as the role of supplying the minimum amount of oxygen for burning the heat generating member F Can be performed.

At this time, the observation unit 12 composed of the long holes is composed of a net made of a fine mesh to divide the inflow of air, reduce the inflow speed of the air to block the stop of the combustion of the heating member F, ) It is possible to minimize irregularity of the combustion region and to prevent irregular combustion.

As shown in FIG. 2B, the observation section 12 may be a microporous structure having a plurality of openings formed along the periphery of the main body 10. The effect of the observation section 12 is that the observation section 12 is made of a long hole, And can be triggered in the same way as in the case of a mesh network.

In addition, when the observation section 12 is composed of a net made of a fine mesh or a plurality of micropores, the inflow of air is divided so as to prevent the heating member F from being stopped from burning, When the user exerts heat on the heat generating member F or heat is transferred to the object on which the main body 10 is installed, it is possible to suppress deformation or deformation of the object.

2C, the observation section 12 can be made of a transparent window other than the above-described elongated hole or micropores to facilitate the observation of the inside accommodation space 11 of the main body 10.

3, the main body 10 is provided with an inflow direction switching portion 13 for switching the inflow direction of the air introduced into the accommodation space 11 at the side wall end portion corresponding to one or more ventilation portions 20 to be described later ).

For example, the inflow direction switching unit 13 is provided with a plurality of circumferential side walls 12, which have a predetermined length and width corresponding to the size of the ventilation part 20, One surface of the surface can be integrally coupled and fixed, and the remaining portion except the surface coupled to the side wall of the main body 10 is in a free state.

Alternatively, at the time of forming the ventilation part 20 in the process of manufacturing the main body 10, the other part of the side wall of the main body 10 excluding the one surface is cut to form the inflow direction switching part 13 as described above You may.

When the air is introduced into the main body 10 in a state in which the remaining portion that is not coupled to the side wall of the main body 10 can freely move, the remaining portion except for the surface fixed to the side wall of the main body 10, The inflow direction switching unit 13 is preferably made of a flexible material so as to effectively achieve a bending deformation or a bending deformation.

The air introduced into the accommodation space 11 by the introduction direction switching unit 13 is guided to the inner circumferential direction of the main body 10 in the direction in which the inflow direction does not directly affect the combustion site of the heating member F Thereby preventing the combustion of the heating member F from being stopped easily by the high velocity of the air and minimizing the shaking of the combustion region of the heating member F to suppress the occurrence of soot due to irregular combustion .

In addition, since the inflow direction of the air is along the inner circumferential direction of the accommodating space 11, as the heated air in the accommodating space 11 rotates and conveys upward, the heated air does not rotate It is possible to increase the flow distance of the air compared to when it is convected, which is to prolong the heat transfer time of the heated air.

As a result, the heat transfer efficiency of the heat generating member (F) can be improved as well as the effect of keeping the temperature constant. Further, since the air is continuously introduced, the combustion efficiency can be further increased. Can be minimized.

The inflow direction switching unit 13 is integrally formed with the main body 10 made of a metal material rather than being made of a flexible material which is deformed or bent flexibly by air introduced through a vent portion 20 described later, It is possible to maintain the bent or bent state inside the ventilation part 20.

Thus, the outer surface of the heating member F or the outer surface of the metal foil M surrounding the heating member F is closely contacted to block the movement of the heating member F, thereby stably fixing the mounting position The space between the heat generating member F and the inner surface of the main body 10 can be maintained, and a minimum air circulation or convection space can be ensured.

4, the main body 10 forms a plurality of cutouts 14 radially outward along the periphery of the opening 40, which will be described later, formed at the lower end of the cutout 14, and the adjacent cutouts 14 A plurality of support protrusions 15 on which the heating member F is placed and a plurality of inlets 16 through which air is introduced into a space between the plurality of support protrusions 15, .

That is, by forming the support protrusions 15, a gap is formed between the heat generating member F placed on the support protrusions 15 and the bottom surface of the main body 10, and the inflow The air flows upward through the gap between the heating member F and the main body 10 through the plurality of inlets 16.

This makes it possible to sufficiently ensure inflow of air for combustion of the heat generating member F so that the flow rate of the air introduced through the ventilation portion 20 or the blocking portion 50 described later is remarkably slow or the inflow amount of the air is insignificant The combustion of the heat generating member F can be stably maintained.

In addition, by forming the plurality of inflow ports 16 by folding the portion between the plurality of support protrusions 15 into close contact with the bottom surface of the main body 10 through a plurality of the incision 14, Partial expansion allows air inflow to be performed more efficiently.

As shown in Fig. 5, the main body 10 is formed along the periphery of the opening 40, which will be described later, formed at the lower end of the main body 10, as another embodiment of the receiving projection 15 and the inlet port 16 of the main body 10 And a plurality of support projections 15 protruding in an embossed shape on which the heat generating member F is placed can be provided between the heat generating member F and the bottom surface of the main body 10 by the formation of the support protrusions 15. [ The air introduced from the opening 40 to be described later can flow upward through the formation of the plurality of inlets 16 in which the air is introduced into the space between the plurality of the support projections 15 as well as the gap.

1 to 4, one or more openings are formed along the periphery of the main body 10 so that the outside air can be introduced into the inside accommodation space 11 of the main body 10 The temperature of the accommodation space 11 is controlled and oxygen is supplied by the heat generating member F to maintain the combustion and heat generation as well as to adjust the burning rate and the calorific value.

The air inside the accommodation space 11 which is supplied from the ventilation part 20 and heated through the heating member F is maintained in a state capable of transmitting heat to the upper side of the main body 10 by the convection action.

The ventilation part 20 is formed of a net made of a mesh of a small size so as to divide the inflow of air and reduce the inflow speed of the air to block the stop of the combustion of the heating member F, Irregular combustion can be prevented by minimizing the shaking of the combustion region.

Here, the vent portion 20 may be formed in a direction that is horizontal or perpendicular to the gravity direction, and may be formed in a diagonal direction different from the above direction so that even if the inflow direction switching portion 13 is not formed, The air heated in the main body 10 rotates along the inner circumference of the main body 10 and conveys the air upward.

Particularly, unlike the case where the air vent 20 is horizontally or vertically aligned with the gravitational direction so that a large amount of air is simultaneously brought into contact with the combustion region of the heating member F, when the air vent 20 is in the diagonal direction, The air is sequentially brought into contact with the combustion region of the heat generating member F so that the stop of combustion of the heat generating member F is blocked and the fluctuation of the burning region of the heat generating member F is minimized to prevent irregular combustion .

1 and 7, the mounting portion 30 is provided on the upper end of the main body 10 so as to be mounted on an object, and various embodiments can be applied to the structure. In the present invention, So that the chair can be mounted on the heat transfer part 100 of the outdoor chair, thereby realizing an outdoor chair equipped with a heating device using a non-power source.

The description of the various embodiments in the configuration of the mounting portion 30 will be made in conjunction with the description of the heat transferring portion 100 which will be described later in connection with the mounting portion 30. [

On the other hand, as shown in Figs. 1, 2, 4, and 5, the opening portion 40 is formed at the center of the lower end of the main body 10 so as to facilitate the replacement of the heat- The size of which can be of a size such that the diameter of the finger of the user is sufficient to be inserted.

When the heat generating member F is in the second stage, the heat generating member F, which has been burned, is close to the inner bottom surface of the main body 10, At this time, the user can push the heating member F from the lower side through the opening 40 to move upward, so that the user can easily separate the heating member F from the accommodation space 11. [

The heating device using the non-power source of the present invention configured as described above may further include a blocking portion 50 for blocking heat transfer to the lower side of the main body 10, At least one opening is formed in the direction perpendicular to the ventilation portion 20 along the circumference of the upper portion of the ventilation portion 20 of the main body 10 as shown in Figs. 1 and 2, And blocks heat conduction of the air heated by the combustion of the heat generating member F to the lower side of the cut-off portion 50.

For example, when the ventilation part 20 is formed in the longitudinal direction along the periphery of the main body 10, the blocking part 50 may be formed at a position above the ventilation part 20 in the lateral direction perpendicular to the ventilation part 20, May be formed along the periphery.

Further, when the above-described blocking portions 50 are formed of a plurality of blocks, the blocking portion 50 may have a similar shape to the upper and lower portions of the body 10 in the gravity direction with respect to the blocking portion 50.

In order to ensure safety in the process of using the non-powered heater, it is preferable that the main body 10 is made of metal When the heating of the main body 10 is performed by the combustion of the heat generating member F, the main body 10 is integrated with the main body 10 of the metallic material, The portion 13 is heated by the combustion of the heating member F so that the metal foil M can be deformed or denatured or can be burnt by the heat transmitted from the inflow direction switching portion 13. [

The structure of the blocking portion 50 is required when the main body 10 is made of a metal material. If the main body 10 is made of a material having heat resistance, such as heat-resistant plastic, The structure of the cut-off portion 50 can be selectively applied according to the material of the body 10. [

It goes without saying that, in addition to the above-described role of supplying oxygen, the blocking portion 50 can also serve as the observation portion 12 mentioned above through its open formation.

In addition, the blocking portion 50 prevents the inflow of air into the accommodation space 11 and the air heated by the heat generating member F from making thermal conduction downward, and prevents the heat accumulation of the main body 10 When the user exerts heat on the heat generating member F or heat is transferred to the object on which the main body 10 is installed, it is possible to suppress deformation or deformation of the object.

6 and 7, the heating device using the non-power source of the present invention constructed as described above can be mounted on a chair for outdoor use, Or by coupling the mounting portion 30 and the fastening portion 130, which will be described later, to each other.
