Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a configuration diagram for explaining the method of using the tent heating apparatus 10 according to an embodiment of the present invention.

As illustrated, the tent heating apparatus 10 according to the present embodiment basically includes an air heating unit 20 and a heating air induction unit 50. The air heating unit 20 has a heat source 12 at its lower portion and is heated by heat rising from the heat source to serve to heat the air, and the heating air induction unit 50 induces the heated air to the tent T.

The heat source 12 may be only a cooking burner or a bonfire. If the fuel of the cooking burner runs out, a bonfire can be burned to drive the heating device 10. For tent heating, there is no need to use expensive and expensive heating means. Also, if you need to heat overnight, you can purchase and operate low-cost firewood without needing to parse precious fuel.

The air heating unit 20 is provided with a casing 21 in the form of a box or a cylinder, and has a heating plate 23 on its top. The heating plate 23 is for use without throwing the heat of the casing 21 itself into the air.

Since the casing 21 receives heat directly from the heat source 12, the casing 21 itself is heated and hot, so the heating plate 23 is placed on the casing 31, and the heating plate 23 is used as a heat source. ) Or a kettle 51 to boil water or to cook the necessary dishes. The heating plate may be a stainless steel flat plate or an iron plate. 8, when the cover 25 is applied to the casing 21, the heating plate 23 is omitted.

In addition, the casing 21 is provided with a cold air inlet 21b and a heated air outlet 21c. The cold air inlet 21b is a passage through which cold air around enters the casing 21. In addition, the heated air outlet 21c is a passage through which heated air heated inside the casing 21 is discharged.

The heating air induction part 50 has an induction pipe 41, a closed connection part 40, and a flow rate control part 45. The sealed connection part 40 serves to detachably connect the induction pipe 41 to the heated air outlet 21c. In addition, the flow rate control unit 45 adjusts the flow rate of the heated air passing through the induction pipe 41. The description of the heated air induction unit 50 will also be described later.

2 is a cross-sectional view showing the internal structure of the air heating unit 20 shown in FIG. 1.

As shown, the air heating unit 20 takes the form of a box, a casing 21 having a cold air inlet 21b and a heated air outlet 21c, and a plurality of fixed inside the casing 21 It is provided with a heat exchange pipe (21e).

The casing 21 can take the form of a hexahedron and provides a heating space 21a. The air flowing through the cold air inlet 21b and exiting through the heated air outlet 21c is heated while passing through the heating space 21a.

In addition, the lower portion of the casing 21 is provided with a leg (21g). The leg 21g separates the casing 21 from the ground G so that the heat source 12 can be positioned under the casing 21. The height of the leg 21g may be varied as needed.

The heat exchange pipe 21e is a pipe member having a certain diameter and extending vertically. In particular, the upper end is blocked and the lower end is opened to the bottom of the casing while being fixed to the bottom plate 21d of the casing 21. A plurality of heat exchange pipes 21e are arranged in a predetermined pattern and fill the heating space 21a. In FIG. 2, although the upper end of the heat exchange pipe 21e is separated from the ceiling surface of the casing 21, the heat exchange pipe 21e can be made longer and fixed to the ceiling surface of the casing 21.

As described above, since the heat exchange pipe 21e is opened downward, it immediately receives heat coming from the heat source 12. The inner space of each heat exchange pipe 21e is utilized as a heat receiving space 21f. Naturally, convection is also performed inside the heat exchange pipe 21e. For example, the heat that has cooled in the heat receiving space 21f falls to the bottom and falls out, and the newly heated heat by the heat source 12 rises to fill the heat receiving space 21f. As a result, the heat exchange pipe 21e receives the heat provided from the heat source 12 and heats the air passing through the heating space 21a in a heated state.

3 is a cut-away perspective view of the air heating unit 20 shown in FIG. 2.

As shown, a plurality of heat exchange pipes 21e are erected on the bottom plate 21d of the casing 21. The arrangement pattern or size of the heat exchange pipe 21e may vary depending on the case. In addition, if necessary, the bottom plate 21d of the casing 21 may be implemented to be disassembled. That is, the side wall and the bottom plate (21d) of the casing 21 can be prefabricated to open the heat exchange pipe (21e) as needed.

FIG. 4 is a cutaway perspective view showing a modified example of the air heating unit shown in FIG. 3.

4, the casing 21 itself may be applied in a cylindrical shape. In the case of FIG. 3, heat may not be properly applied to the heat exchange pipe 21e located at the corner of the square bottom plate, but when the casing is applied in a cylindrical shape, sufficient heat is transferred to the heat exchange pipe of the outer portion. Even if the casing 21 is cylindrical, it is natural that the cold air inlet 21b and the heated air outlet 21c are applied.

FIG. 5 is an exploded perspective view of the hermetic connection 40 shown in FIG. 1.

As described above, the sealing connection portion 40 serves to detachably connect the induction pipe 41 to the heating air outlet 21c. The reason for the detachable implementation is naturally considering the convenience of transportation.

In order to apply the sealed connection portion 40, a square flange 21k and a fixed hinge 21m are provided at an end of the heated air outlet 21c. The square flange 21k is a square plate having a certain thickness with a hole drilled in the center, and is welded and fixed to the end of the heated air outlet 21c.

The fixed hinge 21m is a member fixed to the upper end of the square flange 21k and has a horizontal hole 21n. The horizontal hole 21n is a through-hole with a constant inner diameter extending in a direction orthogonal to the longitudinal direction of the heating air outlet 21c, and accommodates and supports the connecting pin 41b.

The sealed connection portion 40, between the corresponding counter 41a of the square to be welded and fixed to the end of the induction pipe 41, the connection pin 41b fixed to the upper end of the counter flange 41a, and the counter flange 41a It consists of a sealing material (41e) interposed in. The sealing material 41e is a heat-resistant rubber that prevents leakage of air.

The corresponding flange 41a is a square plate having a hole in the center and has the same size as the square flange 21k. In addition, the connecting pin 41b is formed by bending a rod-shaped member having a predetermined diameter, and is fitted into the horizontal hole 21n of the fixed hinge 21m. The connecting pin 41b is rotatable while being inserted into the horizontal hole 21n.

When the connecting pin 41b is placed in the horizontal hole 21n, the corresponding flange 41a rotates using the connecting pin 41b as a rotating shaft by the weight of the induction pipe 41 toward the square flange 21k. Pressurized. Since the sealing material 41e is provided between the corresponding flange 41a and the square flange 21k, the heated air outlet 21c and the induction pipe 41 are coupled with the sealing material 41e therebetween. Implement Of course, the user can also raise the guide tube 41 in the direction of the arrow z.

6 is a partial cross-sectional view for explaining the structure of the flow rate adjusting unit 45 shown in FIG. 1.

The flow rate adjusting part 45 serves to control the flow rate of the heated air passing through the induction pipe 41. In particular, the more the wind blows, the higher the flow rate is to increase the flow rate supplied to the tent. It is important to increase the supply of heated air because the colder the wind, the larger the invasion into the tent.

The flow rate adjusting unit 45 is composed of a fan housing 45a, an inner fan 45b, a fan shaft 45c, and an outer fan 45d. The fan housing 45a is a case accommodating the inner fan 45b, and both ends thereof are connected to the induction pipe 41. The heated air moving to the tent through the induction pipe 41 passes through the fan housing 45a.

The inner fan 45b is installed to be rotatable in the fan housing 45a through the fan shaft 45c, and promotes the flow of heated air through rotation. In this regard, it can be seen that the inner fan 45b and the fan housing 45a serve as a casing and a rotor of the centrifugal blower.

In particular, the fan shaft 45c extends to the outside of the fan housing 45a, and is coupled to the outer fan 45d outside the fan housing 45a. The outer fan 45d rotates under the wind pressure of the wind passing around it. It's like a pinwheel and spinning with the wind. Of course, as the wind speed increases, the rotational speed of the outer fan 45d increases.

After all, the outer fan 45d rotates under the wind pressure and serves to rotate the inner fan 45b through the fan shaft 45c. It goes without saying that the rotational speeds of the outer fan 45d and the inner fan 45b are the same. As the wind passing through the periphery of the tent increases, the rotational speed of the inner fan 45b increases, so that the flow amount of air heated in the air heating unit 20 increases.

7 is a view showing a modification of the air heating unit 20 shown in FIG.

Referring to the drawing, it can be seen that the heat source receiving space portion 21p is located under the casing 21. The heat source accommodating space portion 21p is a space secured to receive a heat source and is spaced from the ground G. The heat source accommodating space portion 21p is prepared in case water is accumulated on the ground or the ground is wet due to snow or rain, so that a burner cannot be installed or a campfire cannot be smoked.

It is to heat the air by putting a cooking burner inside the heat source receiving space portion (21p). Or, in the heat source accommodation space part 21p, it puts firewood like fire and lights it to produce air for heating.

8 is a view showing another modified example of the air heating unit shown in FIG. 1.

As shown, the cover 25 may be applied to the upper portion of the casing 21. That is, the upper part of the casing 21 can be opened and the cover 25 can be opened and closed. When the cover 25 is applied in this way, the heating space 21a can be opened as needed, and thus the usability of the heating space 21a can be greatly improved. For example, you can open the cover and put sweet potatoes or potatoes inside the casing 21 to grill and eat.

Reference numeral 27 is a multi-purpose container. The multi-purpose container 27 is disposed on the side of the heat exchange pipe 21e, and is used to contain cooking objects to be boiled or boiled for a long time or to fill water for generating moisture. When the multi-purpose container 27 is filled with water, the heat-evaporated water mixes with the heated dry air and moves to the tent, raising the humidity inside the tent to some extent.

In addition, a humidifying container 22 is mounted on the upper end of any of the heat exchange pipes 21e, and an expansion chamber 28 is installed on the other heat exchange pipes. The humidifying container 22 and the expansion chamber 28 are shown in FIGS. 9 and 10.

As shown in Fig. 9, the humidifying container 22 includes a container body 22a and a holder portion 22b. The container body (22a) is a container opened to the top to accommodate the water for humidification (W). Humidification water is water to be evaporated for humidification. When the multipurpose container 27 is not used for humidification, the humidification container 22 is mounted on the heat exchange pipe 21e to be used. Needless to say, the humidifying container 22 can be detachably attached to the heat exchange pipe 21e.

10 is a partial cross-sectional view for explaining the installation structure of the expansion chamber 28 shown in FIG. 8. In order to install the expansion chamber 28, the upper end of the heat exchange pipe 21e must be opened.

10, the expansion chamber 28 is fixed to the upper end of the heat exchange pipe 21e whose upper end is open. The expansion chamber 28 is for expanding the heat receiving space 21f of the heat exchange pipe 21e. The volume of the heat receiving space 28a provided by the expansion chamber 28 may be changed as needed.

As described above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical spirit of the present invention.
