Fig.

Referring to Figs. 1 to 3, the heating burner includes a first inner chamber 1. Fluid flows into the first inner chamber (1). The fluid may flow from the external heating fluid use portion. The external heating fluid use portion may be one of a radiator, a hot water mat, or the like, which is supplied with the fluid heated by the heating burner. The fluid heated by the present heating burner can be supplied to the external heating fluid use portion, and the heat can be supplied to the first internal chamber 1 after the heat is taken. In the present application, a fluid supplied from the external heating fluid using portion to the first inside chamber 1 will also be referred to as a preheating fluid for convenience of explanation. The fluid before heating may have a temperature of about 60 ° C to 70 ° C.

The first inner chamber 1 can receive the fluid before heating through the inlet pipe 61 provided in the lid 6 at the time of the heating of the heating burner.

In addition, the fluid applied to the present heating burner may be water, for example. However, the type of fluid is not limited to the present invention, and various fluids may be applied as fluids.

1 to 3, the upper portion of the first inner chamber 1 has an opening. Further, the opening portion can be opened and closed (opened and closed) by the lid 6. The lid 6 can be engaged and disengaged with the housing 7 by the annular structure 72 of the housing 7, which will be described later. The opening of the first inner chamber (1) can be closed by the lid (6) when the heating burner is driven. Illustratively, when the opening is opened by the removal of the lid 6, replenishment of the fluid to the first inner chamber 1 through the opening can be made.

1 to 3, the heating burner includes a second inner chamber 2. The second inner chamber (2) receives the first inner chamber (1).

1 to 3, the present heating burner includes the outer chamber 3. Comparing FIGS. 2 and 3, the outer chamber 3 receives the second inner chamber 2 and receives fluid from the first inner chamber 1. The fluid introduced into the outer chamber 3 from the first inner chamber 1 may have a temperature of about 60 캜 to 70 캜 because it is the above-described fluid before heating. 1 to 3, between the inner surface of the upper part of the outer chamber 3 and the outer surface of the second inner chamber 2, the fluid contained in the outer chamber 3 is communicated with the outer chamber 3 and the second The packing portion 31 may be provided so as to be prevented from flowing out between the inner chambers 2. The packing portion 31 may be made of rubber. For example, it may be a silicon ring and may be provided in three layers.

1, the heating burner is arranged so that the fluid in the first inner chamber 1 flows through the second inner chamber 2 and flows into the first inner chamber 1, And a first pipe (4) communicating the inside of the outer chamber (3). As such, the outer chamber 3 receives fluid from the first inner chamber 1 through the first tube 4. The inflow of fluid into the outer chamber 3 through the first tube 4 can be shut off when the capacity of the fluid in the outer chamber 3 reaches the limit (i.e., when the outer chamber 3 is filled with fluid) . In addition, the inflow of the fluid into the outer chamber 3 through the first tube 4 can be blocked by the pressure in the outer chamber 3. As will be described later, when the fluid in the outer chamber 3 is heated, the pressure in the outer chamber 3 can be raised. When the pressure in the outer chamber 3 becomes higher than the pressure in the first inner chamber 1, The inflow of the fluid from the first inner chamber 1 through the first tube 4 to the outer chamber 3 can be blocked.

In addition, the first tube 4 may comprise a check valve which allows only the movement of fluid from within the first inner chamber 1 into the outer chamber 3. Further, as will be described later, the second pipe 5 may include a check valve allowing only the movement of the fluid to the outside.

1 to 3, a washer 41 may be provided around a portion of the first tube 4 which is located in the second inner chamber 2. Further, as will be described later, a washer 51 may be provided around the portion of the second tube 5 located in the second inner chamber 2. The washer 41 provided in the first pipe 4 and the washer 51 provided in the second pipe 5 prevent the bottom surface of the first inner chamber 1 and the bottom surface of the second inner chamber 2 Can be maintained. Further, the outflow of the fluid can be prevented. The washer 41 provided in the first pipe 4 and the washer 51 provided in the second pipe 5 may be copper washers.

A packing unit may be provided to prevent fluid from flowing out between the outer surface of the first tube 4 and the inner surface of the hole into which the first tube 4 of the first inner chamber 1 is inserted.

1 to 3, the upper ends of the first inner chamber 1, the second inner chamber 2, and the outer chamber 3 may be coupled to each other by welding. Bond welding can be done, for example spot welding can be done. The upper portion of the outer chamber 3 can be shielded (sealed) so that the fluid in the outer chamber 3 is prevented from flowing out between the outer chamber 3 and the second inner chamber 2. [

Further, in the outer chamber 3, heating is performed on the fluid. Illustratively, the fluid in the outer chamber 3 can be heated by the heating means. The heating means may be a device capable of applying heat at the lower side of the outer chamber 3. Illustratively, the heating means may be one of a portable gas cylinder, a portable burner, which can be connected to a heating connection 71 of the housing to be described later. However, the configuration applied as the heating means is not limited thereto.

Further, referring to Fig. 1, the heating burner includes a second pipe 5 through which the heated fluid in the outer chamber 3 is discharged to the outside. 1 to 3, the second tube 5 may extend through the first inner chamber 1 and the second inner chamber 2 and extend outwardly. A washer 51 may be provided around the periphery of the portion of the second tube 5 located in the second inner chamber 2. As described above, the washer 51 provided in the second pipe 5 is provided with the washer provided in the first pipe 4 and the interval between the first inner chamber 1 and the second inner chamber 4 Can be maintained.

Further, the fluid heated in the outer chamber 3 can be moved along the second tube 5. The fluid in the outer chamber 3 is expanded when heated and can become bulky. Thereby, the pressure in the outer chamber 3 can be increased, and the fluid heated in the outer chamber 3 by the pressure can be discharged through the second pipe 5. According to the experiment, the fluid heated in the outer chamber 3 is lifted up to a height of 3 m and can be discharged to the outside. Thus, the heating burner can easily supply the heating fluid even when the use of the external heating fluid is provided at a high position such as a roof top tent, a tent above the vehicle roof, or the like. Further, since the heating burner secures a strong pumping force against the heating fluid, the heating fluid can be easily supplied regardless of the arrangement position, and the installation (arrangement) of the heating burner in a safe place can be facilitated.

1 to 3, the second pipe 5 may include a check valve. Thus, even if the pressure in the outer chamber 3 is lowered (for example, as the fluid in the outer chamber 3 is heated and the heated fluid is discharged to the outside through the second tube 5) 3) may be lowered. By the operation of the second pipe 5, the fluid may not flow back in the second pipe 5.

2, the fluid flowing from the first inner chamber 1 to the outer chamber 3 is introduced into the outer chamber 3 for the purpose of maximizing the pressure due to the heating of the fluid in the outer chamber 3, It is desirable to fully fill the accommodation space in the housing. For example, the fluid in the outer chamber 3 can be accommodated in the outer chamber 3 with a water level accommodated up to the lower end of the packing portion 31.

As described above, the gap between the outer chamber 3 and the second inner chamber 2 is sealed by the packing portion 31, and the discharge of the fluid from the outer chamber 3 of the first tube 4 The discharge of the fluid from the outer chamber 3 can be done entirely through the second tube 5. [ Thus, the pressure that is elevated in the outer chamber 3 can be used to discharge through the second tube 5 of the fluid as much as possible.

Further, the outer chamber 3 receives the fluid from the first inner chamber 1 under predetermined conditions. Specifically, the fluid in the first inner chamber 1 can be moved through the first tube 4 to the outer chamber 3 when the pressure in the outer chamber 3 becomes less than the pressure in the first inner chamber 1 have.

As the fluid in the outer chamber 3 is heated and discharged to the outside through the second tube 5, the pressure in the outer chamber 3 can be lowered. The pressure in the outer chamber 3 can be made smaller than the pressure in the first inner chamber 1 and the pressure in the outer chamber 3 becomes smaller than the pressure in the first

inner chamber

1, 1 The fluid in the inner chamber 1 can be introduced into the outer chamber 3 through the first tube 4. In addition, even if the pressure inside the outer chamber 3 is lowered and a condition is generated in which the back flow of the fluid through the second pipe 5 is formed, as described above, the second pipe 5 includes the check valve, The backflow of the fluid through the second pipe 5 can be prevented by the operation of the check valve even when the pressure in the chamber 3 is lowered.

The second inner chamber 2 may also be provided between the outer chamber 3 and the first inner chamber 1 such that the temperature of the fluid in the first inner chamber 1 is below a predetermined temperature. The second inner chamber 2 can minimize or prevent heat from being heated by the fluid in the outer chamber 3 from being transferred into the first inner chamber 1. [

For example, the second inner chamber 2 maintains the gap between the fluids received in the first inner chamber 1 and the outer chamber 3, thereby reducing the temperature of the fluid in the first inner chamber 1 to a predetermined temperature . &Lt; / RTI > 2, if there is no second inner chamber 2, the fluid in the outer chamber 3 may surround the first inner chamber 1 and may be heated by the heating means, It is possible to heat the fluid in the inner chamber 1 before heating. To prevent this, it is necessary to form a gap between the fluid accommodated in the outer chamber 3 and the first inner chamber 1, and the second inner chamber 2 can exert such an effect.

1 to 3, a side surface of the first inner chamber 1 and a side surface of the second inner chamber 2 are formed on the side surface of the second inner chamber 2, A protrusion 21 protruding toward the inner chamber 1 may be formed. Accordingly, the gap between the first inner chamber 1 and the fluid accommodated in the outer chamber 3 can be sufficiently secured by the second inner chamber 2. Further, the gap between the lower surface of the first inner chamber 1 and the bottom surface of the second inner chamber 2 can be formed or maintained by the first tube 4. For example, as will be described later, the first tube 4 is threadedly engaged with the first inner chamber 1 and the second inner chamber 2, respectively, so that the lower surface of the first inner chamber 1 and the second inner chamber 2 The first inner chamber 1 and the second inner chamber 2 can be joined such that a gap between the bottom surfaces of the first inner chamber 1 and the second inner chamber 1 is formed. Further, the above-described washer 41 can maintain the gap by supporting the lower surface of the first inner chamber 1 against the bottom surface of the second inner chamber 2.

As described above, the air layer is formed by the gap (gap) formed between the second inner chamber 2 and the first inner chamber 1, so that the heat from the outer chamber 3 flows into the first inner chamber 1 It can be blocked from being transmitted. That is, the interval (gap) formed between the second inner chamber 2 and the first inner chamber 1 can serve as a cooling function.

The protrusions 21 may be formed on the side surface of the second inner chamber 2 at intervals along the circumference of the second inner chamber 2. Illustratively, referring to FIG. 4, three protrusions 21 may be formed around the circumference of the second inner chamber 2 at regular intervals.

The protrusions 21 are formed on the outer circumferential surface of the first inner chamber 1 so that the temperature of the fluid in the first inner chamber 1 is lower than the predetermined temperature, And may have a protruding length that forms an interval. For example, the protruding length of the protruding portion 2 (largest depth in the horizontal direction (from 3 o'clock to 9 o'clock in FIG. 1 to 3) can be 0.5 mm.

The predetermined temperature is set to 85 deg. C or lower so that the temperature in the outer chamber 3 is reduced as the fluid in the first inner chamber 1 flows into the outer chamber 3 to form a negative pressure in the outer chamber 3. [ Can be set.

2 and 3, the pressure in the outer chamber 3 becomes smaller than the pressure in the first inner chamber 1, as described above, according to the present heating burner, When the fluid in the chamber 1 is introduced into the outer chamber 3 through the first tube 4, the temperature of the outer chamber 3 (which is formed experimentally to form 150 ° C to 200 ° C) ) Can be lowered (quenching) due to the fluid (preheating fluid) flowing from the first inner chamber 1 and a negative pressure is formed in the outer chamber 3 due to a sudden lowering of the temperature, The water in the chamber 1 can be rapidly introduced into the outer chamber 3 by the negative pressure. Further, the fluid contained in the first inner chamber 1 at the time of negative pressure formation by the negative pressure formed in the outer chamber 3 can be sucked into the outer chamber 3. Further, to describe sound pressure in more detail, the outer chamber 3 can be expanded in volume by being heated by the heating of the heating means for the fluid contained therein. However, when the fluid is introduced from the first inner chamber 1 into the outer chamber 3 while the fluid is inflated in such a volume, the volume of the outer chamber 3 may be reduced due to the rapid temperature drop. A negative pressure may be generated in the outer chamber 3 due to the volume reduction.

In this way, in order for the temperature change due to the fluid flowing from the first inner chamber 1 to occur in the inside of the outside chamber 3 for generating the negative pressure to occur, the fluid before heating in the first inside chamber 1 and the outside chamber 3) There must be a difference in the temperature of the heated fluid within. Thus, as described above, the second inner chamber 2 is arranged so that the temperature of the fluid in the first inner chamber 1 is not raised above the predetermined temperature by heat due to the heating of the fluid in the outer chamber 3, The distance between the first inner chamber 1 and the outer chamber 3 can be maintained by the inner chamber 2.

Further, the predetermined temperature may be set to 85 DEG C or lower so that a negative pressure is formed in the outer chamber 3 due to the fluid flowing from the first inner chamber 1. [ However, the predetermined temperature may preferably be set to 80 DEG C or less.

Further, as described above, since the temperature of the fluid before heating is 60 ° C to 70 ° C, it is preferable that the fluid before heating in the first inside chamber 1 has a temperature range of 55 ° C to 80 ° C. To be more specific in relation to the lower limit of the temperature of the fluid before heating, when the temperature of the fluid before heating is too low, the heating time may be prolonged during heating in the outer chamber 3 of the fluid before heating. It is preferable that the temperature of the fluid in the chamber 1 is formed within a temperature range of 55 占 폚 to 80 占 폚. For this purpose, it is preferable that the interval between the first inner chamber 1 and the second inner chamber 2 is formed at an appropriate interval so as not to be excessively large.

1 to 3, the second tube 5 may be disposed such that its lower end faces the bottom surface of the outer chamber 3. [ Further, the interval between the lower end of the second tube 5 and the bottom surface of the outer chamber 3 can be preset. The predetermined interval is set so that a predetermined amount of the heated fluid discharged through the second pipe 5 out of the heated fluid in the outer chamber 3 is discharged to the outside through the second pipe 5, Some of the steam may be set to flow into the second pipe (5). For example, if the distance between the second tube 5 and the bottom surface of the outer chamber 3 is long, that is, if the height of the lower end of the second tube 5 is high in the outer chamber 3, The water vapor (formed by evaporation of the heated fluid) in the outer chamber 3 is completely introduced into the second pipe 5 before the heated fluid in the inner chamber 3 is discharged to the outside through the second pipe 5, A part of the power (energy) for discharging the heated fluid in the chamber 3 through the second pipe 5 to the outside can be lost. Therefore, the interval between the lower end of the second pipe 5 and the bottom surface of the outer chamber 3 for discharging the heated fluid to the outside through the second pipe 5 is maximized . Illustratively, the spacing may be 1 mm. Also, for reference, the predetermined amount of the heated fluid in the outer chamber 3 that is discharged to the outside through the second tube 5 is the amount of the heated fluid in the outer chamber 3 And may be the maximum amount discharged to the outside through the second pipe 5.

Further, at least a part of each of the first tube 4 and the second tube 5 may have a thread on the outer surface. For example, threads may be formed on the outer surface of a portion of each of the first and

second tubes

4 and 5, which is coupled to the first inner chamber 1 and the second inner chamber 2, respectively, Each of the first pipe 4 and the second pipe 5 can be screwed to the first inner chamber 1 and the second inner chamber 2, respectively. Accordingly, the first inner chamber 1 and the second inner chamber 2 can be mutually coupled by only arranging the first tube 4 and the second tube 5.

As described above, the first tube 4 includes a check valve that allows only the movement of the fluid from within the first inner chamber 1 into the outer chamber 3, and the second tube 5 includes the outer side And may include a check valve that only allows movement of fluid out of the chamber. The first tube 4 comprising the check valve may include balls that move within it and open and close the inner passageway to allow only the movement of fluid from within the first inner chamber 1 into the outer chamber 3 have. The ball may be a ceramic ball weighing 1/10 of the same volume. Only the movement of the fluid from within the first inner chamber 1 into the outer chamber 3 can be achieved by the ball. In addition, the check valve may be provided with a buffering portion for buffering the ball against the pressure in the outer chamber 3. The buffer can be made of rubber. The check valve portion of the second pipe 5 may have the same structure as the check valve of the first pipe 4 so that only the use of the fluid from the outside chamber 3 to the outside is allowed.

1 to 3, the heating burner may include a housing 7 in which the outer chamber 3 is accommodated. Although not shown in detail in the drawings, the housing 7 may be a cylindrical perforated mesh container having a mesh structure in which a plurality of holes are formed. The upper portion of the housing 7 may be provided with an annular structure 72 which enables the lid 6 and the housing 7 to be detached (attached or detached). The first inner chamber 1, the second inner chamber 2 and the outer chamber 3 which are mutually coupled to each other can be disposed in the housing 7 at a predetermined distance from the bottom surface of the housing 7. For example, the upper end of at least one of the first inner chamber 1, the second inner chamber 2, and the outer chamber 3 mutually coupled is supported at the upper end of the housing 7, so that the first inner chamber 1, The second inner chamber 2, and the outer chamber 3 can be disposed in the housing 7.

Further, the lid 6 may be provided with a ring for hanging the heating burner on the outer structure. In addition, the lid 6 may be provided with a temperature measurement hole into which a part of the temperature measuring device can be inserted. The temperature measuring device can be inserted into the first inner chamber 1 from the outside through the temperature measurement hole to measure the temperature in the first inner chamber 1. [

1 to 3, the heating burner may include a support structure 8 on which the housing 7 can be mounted. The support structure 8 may be tri-valent.

In addition, a heating connection portion 71 connected to the heating means may be provided at a lower portion of the housing 7. Although not shown in the drawing, the heating means may be a portable gas cylinder, a portable burner, or the like, which is connected to the heating connection portion 71. The heating connection portion 71 may have a cylindrical plate structure so that the flame of the heating means can be stably collected in the container without being scattered to the outside.

According to the present heating burner, since the first chamber 1 in which the fluid flows before heating and the third chamber 3 in which the fluid is heated are not in a single configuration, in other words, The instantaneous heating time can be shortened. According to the present heating burner, since the fluid is not discharged from the outer chamber 3 except for the second pipe 5, when the pressure is raised by the heating of the fluid in the outer chamber 3, The rising pressure can be used for the natural circulation of the fluid while the fluid is prevented from overflowing to the outside of the outer chamber 3 with the rise. Specifically, due to the upward pressure, the fluid can be discharged to the outside through the second tube 5, and the pressure of the outer chamber 3 is lowered through the discharge through the second tube 5 of the heated fluid The fluid of the first inner chamber 1 can naturally flow into the outer chamber 3 when the pressure of the outer chamber 3 becomes smaller than the pressure in the first inner chamber 1 and the fluid in the first inner chamber 1 The inner temperature of the outer chamber 3 is cooled by the inflow of the fluid before heating from the inner chamber 3 to the outer chamber 3 and the vacuum in the vacuum state is generated so that the fluid in the first inner chamber 1 is sucked into the outer chamber 3 . At this time, the inflow of the fluid from the outside into the first inner chamber 1 can be performed. As such, the circulation of the suction and the thermal expansion of the fluid can be naturally carried out by the heating burner itself without additional means such as a pump.
