A fireplace that automatically diffuses hot air using a non-powered fan

Abstract

The present invention relates to a fireplace that automatically circulates air by driving a non-powered fan to maintain a constant temperature inside and outside the fireplace, thereby improving heating efficiency and solving the problems of incomplete combustion, soot generation, and safety.

Description

[Technical Field]

[0001] The present invention relates to a fireplace, and more particularly to a fireplace that can maintain a constant temperature in a room or indoors by automatically forcing air circulation through the drive of a non-powered fan. [Background technology]

[0002] Fireplaces burn fuel to generate heat and warm a room or indoor space. However, the heated air gradually spreads from the area around the fireplace, relying solely on natural convection, but it takes a long time to heat the entire room or indoor space, resulting in high heating costs. In other words, because the air heated by the heater rises and is heated from above, it takes a long time to heat the air in areas a little distance from the fireplace, and heating costs are also high.

[0003] For this reason, the applicant of the present invention has proposed an "assembled air circulator using a non-powered fan" (prior document) in Korean Patent Registration No. 10-1949088. The prior document is equipped with a thermoelectric generator that generates electricity from the temperature difference between one side to which hot air from a fireplace is transferred and the other side that contacts a cooling plate, and the thermoelectric generator generates electricity that can drive a fan motor when the temperature difference between one side and the other side is equal to or greater than a specific value.

[0004] On the other hand, the "assembled air circulator with a non-powered fan" disclosed in the prior art document is used by placing it on top of the fireplace, and this configuration has a problem: as the airflow from the blower fan moves downward, it also flows into the combustion area of ​​the fireplace body. This causes problems such as incomplete combustion and soot in the wick of the combustion area due to the airflow, and also poses safety issues. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Korean Patent No. 10-1949088 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, the object of the present invention is to provide a fireplace that automatically diffuses hot air using a non-powered fan, so that the wind from the blower fan does not affect the combustion part at all, and the heated air can be automatically circulated throughout the room or the entire room in a shorter time. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a fireplace including a combustion heat generating section 20 that receives fuel F from a fuel tank 10 and burns the fuel F, and a case 30 that surrounds the combustion heat generating section 20, The fuel tank 10 is formed with a hollow hole 10a penetrating vertically, and the hollow hole 10a is connected to a hollow hole 22a of a heat generating mesh body 22 constituting the combustion heat generating portion 20. A vertical pipe 40 extending vertically is formed inside the case 30. The vertical pipe 40 passes through the hollow hole 22a of the heating net 22 and the hollow hole 10a of the fuel tank 10. A blower fan 60 is connected to the shaft of a motor 62, which generates power using electricity generated in the thermoelectric generator 50, and is driven at the lower end of the vertical pipe 40. The motor 62 connected to the blower fan 60 is automatically driven by the thermoelectric power generation unit 50, which generates electricity using the combustion heat generated in the combustion heat generation unit 20, so that some of the warm air generated in the combustion heat generation unit 20 is released to the hot air diffusion holes 30b at the top of the case 30, and some is sucked into the upper end of the vertical pipe 40 by the operation of the blower fan 60 and then forcibly discharged to the lower end. [Effects of the Invention]

[0008] The present invention has the advantage that the room or the entire room can be quickly heated by forcibly circulating the heated air downward, and in particular, the wind forced downward by the blower fan 60 moves only through the inside of the vertical pipe 40, and therefore does not affect the combustion section 20 at all, thereby solving problems such as incomplete combustion, soot generation, and safety.

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0011] Referring to Figure 1, the fireplace comprises a combustion heat generating section 20 that receives fuel F from a fuel tank 10 and burns it, and a case 30 that completely surrounds the combustion heat generating section 20. However, a detailed description of the basic, well-known configuration of a fireplace will be omitted, and only the characteristic configuration of the present invention will be described in detail.

[0012] Referring to Figures 1 to 4, a fireplace 2 that automatically diffuses hot air using a non-powered fan according to an embodiment of the present invention has a fuel tank 10 at the bottom and a combustion heat generating unit 20 attached to the top of the fuel tank 10.

[0013] In particular, a hollow hole 10a is formed in the fuel tank 10, penetrating it vertically. The hollow hole 10a is configured to communicate with a hollow hole 22a of a heat generating mesh body 22 that constitutes the upper combustion heat generating section 20.

[0014] In order to form the hollow hole 10a, the fuel tank 10 is configured such that the lower body 12 extends upward from the hollow hole 10a as the center to form an inner wall body 12a, with the interior 11 of the container of the fuel tank 10 as the reference, and the upper body 14 extends upward from the inner wall body 12a with a separated space 16 on the outside, with the interior 11 of the container of the fuel tank 10 as the reference, to form an outer wall body 14a. With this configuration, the hollow hole 10a is formed in the fuel tank 10, and the separated space 16 is connected to the interior 11 of the container.

[0015] A wick 24 is inserted through a separated space 16 connected to the interior 11 of the container, so that fuel F filled in the interior 11 of the container is supplied to the wick 24. The wick 24 can be moved up and down by operating an adjustment knob 25 to adjust the flame power.

[0016] The case 30 surrounding the combustion heat generating part 20 has an air inlet 30a at the bottom and a hot air diffusion hole 30b at the top, and an upper cover 32 is attached to the top end to separate it from the outside.

[0017] A vertical pipe 40 extending vertically is provided inside the case 30, and passes through the hollow hole 22a of the heating net 22 and the hollow hole 10a of the fuel tank 10. A blower fan 60 is provided at the lower end of the vertical pipe 40, and is connected to the shaft of a motor 62 that generates power using electricity generated in the thermoelectric generator 50, so that the fan 60 rotates automatically when the temperature rises due to combustion.

[0018] The blower fan 60 has a top plate 64 and a bottom plate 65 at the bottom of the fuel tank 10 for smooth positioning. The top plate 64 and the bottom plate 65 are separated vertically by support pins 66, and the blower fan 60 and the motor 62 are coupled and fixed in the space between them. At this time, a through hole 64a formed in the center of the top plate 64 communicates with the lower end of the vertical pipe 40.

[0019] The thermoelectric generator 50 is provided with a heat conduction plate 52 located near the heat generating mesh 22 to receive the heat generated by the heat generating mesh 22, and a thermoelectric device 54 that receives the heat from the heat conducting plate 52 on one side and generates electricity from the temperature difference by contacting a heat dissipation plate 56 on the other side. The basic operating principle of the thermoelectric generator 50 is disclosed in Korean Patent Registration No. 10-1949088, entitled "Assembly-type air circulator using a non-powered fan," filed by the applicant of the present invention, and therefore a detailed description thereof will be omitted.

[0020] Referring to Figure 2, in the fireplace 2 of the present invention having the above-described configuration in which air is forcedly circulated by driving a non-powered fan, external air first enters through the air inlet holes 30a and is directly heated by the fire as it passes through the combustion heat-generating unit 20. At this time, the heat conduction plate 52 of the thermoelectric generator 50 located near the heat-generating mesh 22 transfers heat to the thermoelectric device 54, which then uses the transferred heat to generate electricity.

[0021] The motor 62 connected to the blower fan 60 is automatically driven by the electricity generated by the thermoelectric device 54. As the blower fan 60 rotates, some of the warm air heated in the combustion section 20 escapes through the hot air diffusion holes 30b formed at the top of the case 30, and some of the air is sucked into the upper end of the vertical pipe 40 by the operation of the blower fan 60 and then forcibly discharged to the lower end of the fireplace.

[0022] In this way, the warm air is forcibly circulated downward, quickly heating the room or the entire room, thereby improving heating efficiency. In particular, the air forced downward by the blower fan 60 moves only through the interior of the vertical pipe 40, and does not affect the combustion section 20 at all, thereby eliminating the problems of incomplete combustion, soot generation, and safety that have been pointed out as problems with conventional systems.

[0023] Furthermore, according to the present invention, when adding components for forcibly discharging heated air indoors or to the lower end of an indoor fireplace, the only increase in height is the amount of the components of the blower fan 60. In other words, there is no bulkiness on the sides, and the existing shape is not significantly altered.

[0024] Although specific embodiments have been described above in the detailed description of the present invention, various modifications can be made to the above-described embodiments without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but by the claims and their equivalents. [Industrial Applicability]

[0025] The present invention is used in fireplaces where automatic diffusion of hot air is achieved by an unpowered fan.
