Description

The present invention relates to a heater that heats a room using combustion gas produced by combustion in a burner section.

Conventionally, this type of product had a burner section installed directly in the heat dissipation section, and heat was radiated by heating the front surface of the flat box-shaped heat dissipation section, but since the combustion gas in the burner section flows directly to the heat dissipation section, Uneven heating occurs in some parts, making it impossible to obtain uniform and efficient heat dissipation, and there is also a risk of burnout in parts where heat is concentrated.

Therefore, in the heat dissipation section, a ventilation means consisting of a plurality of small holes is provided in the partition plate that partitions the front side, which is the heat dissipation surface, and the back side, which has the inlet and outlet for the combustion gas. The opposing center portions were made dense and the end portions facing the outflow port were formed to be coarse, or the small hole in the center portion facing the inflow port was formed to be larger than the small hole facing the outflow port. (For example, see Patent Document 1.)

By the way, in this conventional device, an inlet through which combustion gas flows into the heat radiator is provided in the center of the heat radiator, and an outlet through which the combustion gas that has flowed into the heat radiator flows out from the heat radiator is provided at the end of the heat radiator. The combustion gas that flows in from the inlet flows directly to the outlet, and the combustion gas that passes through the small holes in the partition plate between the inlet and the outlet also flows directly to the outlet, and the central part of the heat dissipation part is at a high temperature, causing heat dissipation. The temperature of the part opposite the outlet of the heat sink is low, which inevitably causes temperature unevenness in the heat dissipation part, making it difficult to increase the amount of radiation from the heat dissipation part.

In order to solve the above problems, claim 1 of the present invention includes a heat radiating part that circulates and radiates the combustion gas generated by combustion in the burner part, a front side that becomes a heat radiating surface in this heat radiating part, and a front side that serves as a heat radiating surface, and a A partition plate is provided that partitions an inflow port and a back side having an outflow port, the inflow port is provided at the center of the back side, the outflow port is provided at one end of the back side, and the partition plate has a plurality of In a heater having a ventilation means formed of a small hole, the diameter of the small hole of the ventilation means increases as it moves away from the outlet, and the small hole near the end opposite to the outlet has a diameter that increases as the distance from the outlet increases. , which has a burring portion formed in a convex shape toward the front around the hole.

Further, in claim 2, the partition plate is formed in a shape having a central flat part and bent parts above and below the partition plate, and the small hole having a burring part formed in a convex shape around the hole is formed in the flat part. It is something.

Further, in claim 3, the front side of the heat radiating part is formed to have an uneven cross section, and a small hole having a burring part formed in a convex shape around the hole is formed in a portion of the front side of the heat radiating part having a convex cross section. It was set up so that the

According to a fourth aspect of the present invention, the left and right ends of the partition plate are bent to form a bent portion, and the bent portion on the outlet side is formed larger than the bent portion on the opposite side of the outlet.

According to claim 1 of the present invention, the diameter of the small hole serving as a ventilation means formed in the partition plate of the heat dissipation section increases as it moves away from the outlet side, and the small hole near the end opposite to the outlet increases in diameter. , since it has a burring part formed in a convex shape around the hole, the more combustion gas passes through the small hole as it moves away from the outlet side, the whole heat dissipation part is evenly heated, and furthermore, the burring part is formed in a convex shape around the hole. Combustion gas is guided to the convex part of the formed small hole and hits the heat radiating part in front of the small hole, which prevents the combustion gas from hitting the part on the opposite side of the heat radiating part from the outlet, thereby preventing temperature unevenness in the heat radiating part. However, the entire heat radiating section can be heated efficiently and the amount of radiation from the heat radiating section can be increased.

Further, according to claim 2, the partition plate is formed in a shape having a central plane part and bent parts above and below the partition plate, and by forming the partition plate in the plane part, the entire small hole approaches the heat dissipation part evenly, and the hole Since the small hole with the burring part formed in a convex shape around the radiating part approaches the heat radiating part, the combustion gas hits the entire heat radiating part, preventing the occurrence of temperature unevenness in the heat radiating part, efficiently heating the entire heat radiating part, and increasing the temperature of the heat radiating part. The amount of radiation can be increased.

According to claim 3, the front side of the heat radiating part is formed with an uneven cross section, and the small hole having a burring part formed in a convex shape around the hole is formed in the convex cross section on the front side of the heat radiating part. Since the front side of the heat dissipation part is formed with an uneven cross section, the strength of the heat dissipation part is increased, and the area around the hole is formed in a convex shape on the front side of the heat dissipation part with a convex cross section. By positioning the small hole with a burring part formed in a convex shape around the hole, the combustion gas from the small hole with a burring part formed in a convex shape around the hole hits the convex cross section on the front side of the heat dissipation part and is heated, thereby dissipating heat. It is possible to prevent the occurrence of temperature unevenness in the heat dissipation section, efficiently heat the entire heat dissipation section, and increase the amount of radiation from the heat dissipation section.

According to claim 4, both ends of the partition plate are bent to form bent portions, and the bent portion on the outflow port side is formed larger than the bent portion on the opposite side of the outflow port, so that the large outflow port is formed. The bent part on the side makes it difficult to short-cut the combustion gas, and the bent part on the opposite side of the outlet is formed small to make it easier for the combustion gas that has flowed to the opposite side of the outlet to wrap around the edge of the partition plate. Since the heat flows towards the heat sink, it is possible to prevent temperature unevenness in the heat sink, efficiently heat the entire heat sink, and increase the amount of radiation from the heat sink.

Next, an embodiment to which the present invention is applied will be described based on the drawings.
As shown in FIG. 1, reference numeral 1 denotes a burner section, which receives combustion air from a combustion fan 2 and fuel from a fuel supply means (not shown) and burns it to generate combustion gas. It is.

?3 is a prismatic combustion cylinder located on the burner part 1 and communicated with the burner part 1, and a flat central heat dissipation part 4 communicates with the upper part.
??The back side of this heat dissipation part 4 has a shape that protrudes slightly outward, and has a combustion gas inlet 5 at the center of the back side, which is the lower side toward the front side. In the actual mobile phone, an outlet 6 is provided on the right side when facing the user.

Reference numeral 7 denotes a horizontally long partition plate provided at the center to partition the inside of the heat dissipation section 4 into front and rear parts, and includes a flat part 8 in the center, an upper bent part 9 above the flat part 8, and a flat part 9 as bent parts above and below the flat part 8. It consists of a downwardly bent part 10 below part 8.
As a means for venting the combustion gas from the inlet 5, a plurality of small holes 11 with a diameter of 5 mm are formed near the inlet 5 at the center of the flat part 8, and a small hole 12 with a diameter of 4 mm is formed on the left side of the outlet 6. A plurality of small holes 13 each having a diameter of 12 mm are formed on the combustion gas turning side on the right side.

Further, no small holes are formed in the upper bent part 9 as ventilation means, and a plurality of small holes 11 with a diameter of 5 mm are formed near the central inlet 5 in the lower bent part 10 as ventilation means. A plurality of small holes 12 with a diameter of 4 mm are formed on the left side of the outlet 6, and a plurality of small holes 14 with a diameter of 7 mm are formed on the right side of the combustion gas turning side.

Also, among the small holes 13 with a diameter of 12 mm formed on the right side of the flat part 8 where the combustion gas turns back, there are bead parts formed in upper, middle, and lower stages with a convex cross section on the front side of the heat dissipation part 4, which will be described later. The small holes 13 located in the bead portions 21 formed in the middle and lower portions of the holes 21 have burring portions 15 formed around the holes in a convex shape forward by burring processing.

The partition plate 7 is supported at three points within the heat dissipation section 4, and is fixed by spot welding 16 at one point at the lower center end.When viewed from the front, the upper left end and the upper right end have wire diameters of 33 mesh and wire diameter φ0. 29. A wire mesh (not shown) made of a highly heat-resistant iron-chromium aluminum alloy is folded back to cover the top of the back and fixed by spot welding, and from above these two wire meshes do not normally touch. , is supported by a left support metal fitting 17 and a right support metal fitting 18 so as to come into contact at a plurality of points with the intersecting parts of the wire mesh braid only during thermal expansion due to heating, and the other end of this left support metal fitting 17 is a heat dissipation part. The other end of the right support metal fitting 18 is welded and fixed to the side of the partition plate 7 within the heat dissipation part 4 .

Further, the left and right ends of the partition plate 7 are bent together to form a right bent part 19 and a left bent part 20 as bent parts, and the left bent part 20 on the side of the outlet 6 has a bending length. The right bent portion 19 on the opposite side of the outlet 6 has a bent length shorter than the left bent portion 20 to narrow the space through which the combustion gas passes. It makes the space wider.

On the other hand, on the front side of the heat dissipation part 4, a far-infrared paint is applied as a heat dissipation surface to emit far-infrared rays, and a plurality of bead parts 21 are formed in the upper, middle, and lower stages for reinforcement to dissipate the heat. The front side of the portion 4 is formed to have an uneven cross section, and the portion of the front side of the heat dissipating portion 4 having a convex cross section forms a bead portion 21 forward.

22 is a heat exchanger through which the combustion gas after passing through the heat radiating part 4 flows, and is located on the back side of the heat radiating part 4 and is composed of a plurality of pipes arranged in parallel, and through which the combustion gas after heating the heat radiating part 4 flows. By doing so, the air blown by a convection fan (not shown) is exchanged with heat and released into the room as warm air.

23 is a large viewing window formed in the front of the combustion tube 3 so that the blue flame formed by combustion in the burner section 1 can be seen.
Reference numeral 24 denotes an operation section provided on the upper front side of the instrument body 25, 26 a display section for displaying operation details and operating status of the operation section 24, and 27 a guard body that covers the front surface of the instrument body 25.

Next, the operation of this embodiment will be explained.
Now, combustion gas generated by combustion in the burner section 1 flows from the combustion tube 3 into the heat radiation section 4 through the inlet 5.
At this time, since the entire surface of the flat part 8 of the partition plate 7 is located at equal intervals with the entire front surface of the heat radiating section 4, the small holes 11, 12, 13, which are ventilation means of the partition plate 7, are located at equal intervals with the entire front surface of the heat radiating section 4. so that heat is transmitted to the entire front surface of the heat radiating section 4.

The combustion gas flows from the inlet 5 to the outlet 6 as shown by the arrow A in FIG. , 12, 13, and 14, the combustion gas flows toward the outlet 6. As shown by the arrow C, the combustion gas passes from the inlet 5 to the small holes 11, 12, 13, and 14, which are ventilation means of the partition plate 7. The combustion gas flows to the opposite end of the outlet 6 without stopping, and then folds back the partition plate 7 and separates into combustion gas, which flows toward the outlet 6.

The combustion gas indicated by the arrow A heats the part of the partition plate 7 from the inlet 5 to the outlet 6, and part of the combustion gas flows from the inlet 5 to the outlet 6 on the way to the partition plate 7. The heat flows through the small holes 11 and 12 to the front surface inside the heat radiating section 4, and heats the area from the center of the front surface of the heat radiating section 4 to the outlet 6.

Here, the left bent portion 20 on the outlet 6 side of the partition plate 7 has a longer bending length than the right bent portion 19 to narrow the space through which the combustion gas passes, so that the combustion gas flows from the inlet 5. It is difficult to flow toward the outlet 6, reducing the shortcut of combustion gas from the inlet 5 to the outlet 6, and allowing the combustion gas to flow to the end of the partition plate 7 opposite to the outlet 6. Thus, the entire heat radiating section 4 can be heated efficiently.

Furthermore, since the small holes 12 near the outlet 6 of the partition plate 7 are smaller than the small holes 11 near the inlet 5, the combustion that passes through the small holes 12 in the part from the inlet 5 to the outlet 6 of the partition plate 7 The combustion gas is suppressed to pass through the small hole 12 near the outlet 6 of the partition plate 7 and take a short cut to the outlet 6, and the combustion gas flows to the end of the partition plate 7 opposite to the outlet 6. In this way, the entire heat radiating section 4 can be heated efficiently.

In addition, the combustion gas indicated by the arrow B passes through the small hole 11 near the inlet 5 of the partition plate 7 and flows to the front side of the heat radiating part 4 while heating the area near the inlet 5 of the partition plate 7. Heat the area around the center.

Further, the combustion gas indicated by the arrow C is heated from the inlet 5 to the end opposite to the outlet 6 of the partition plate 7, while flowing from the inlet 5 to the end opposite to the outlet 6. A part of the combustion gas passes through the small holes 11, 13, and 14 of the partition plate 7, flows to the front inside of the heat radiating section 4, and heats from the center of the front surface of the heat radiating section 4 to the end opposite to the outlet 6.

Furthermore, the small holes 13 near the end opposite to the outlet 6 of the partition plate 7 are located at the upper stage of the bead part 21 formed on the front side of the heat dissipating part 4, and the small holes 13 located at the upper stage of the bead part 21 formed on the front side of the heat dissipating part 4 are located at the middle and lower stages of the bead part 21. The combustion gas passes through the small holes 13 more easily and heats the upper stage of the bead portion 21, whereas the small holes 13 near the end opposite to the outlet 6 of the partition plate 7 heat the heat dissipating portion 4. It is difficult for combustion gas to pass through the small holes 13 located at the middle and lower stages of the bead portion 21 formed on the front side of the bead portion 21 compared to the small holes 13 located at the upper stage of the bead portion 21. The convex burring 15 is formed by burring, etc., and the tip of the burring 15 of the small hole 13 is brought close to the bead 21 side. The bead portion 21 near the end is also sufficiently exposed to the combustion gas and heated, making it possible to maintain the entire heat radiation portion 4 at a uniform temperature.

As described above, the small holes 11, 12, 13, and 14, which are ventilation means formed in the partition plate 7 of the heat dissipation part 4, increase in diameter as they move away from the outlet 6, and Since the small hole 13 near the end of the hole is formed with a convex burring part 15 around the hole, the more combustion gas passes through the small holes 11, 12, 13, and 14 as it moves away from the outlet 6 side, The whole is heated uniformly, and the combustion gas is guided to the burring part 15 formed in a convex shape around the hole of the small hole 13 and hits the heat radiating part 4 in front of the small hole 13, so that the outlet of the heat radiating part 4 is heated. The combustion gas hits the part on the opposite side of the heat radiating section 6 to prevent temperature unevenness in the heat radiating section 4, and the entire heat radiating section 4 can be efficiently heated to increase the amount of radiation from the heat radiating section 4.

Moreover, by forming the partition plate 7 in a shape having a central plane part 8, an upwardly bent part 9 above the plane part 8, and a downwardly bent part 10 below the plane part 8, and forming it in the plane part 8, The small holes 11, 12, and 13 all approach the heat radiating part 4 evenly, and the burring part 15 formed in a convex shape around the hole of the small hole 13 approaches the heat radiating part 4, so that the combustion gas hits the entire heat radiating part 4 and dissipating the heat radiating part. 4 can be prevented from occurring, the entire heat radiating section 4 can be heated efficiently, and the amount of radiation from the heat radiating section 4 can be increased.

Further, the front side of the heat dissipating part 4 is formed to have an uneven cross section, and the burring part 15 of the small hole 13 formed in a convex shape around the hole is located in the convex cross section on the front side of the heat dissipating part 4. Since the front side of the heat dissipating part 4 is formed with an uneven cross section, the strength of the heat dissipating part 4 is increased, and the area around the hole on the front side of the heat dissipating part 4 is formed in a convex shape. Due to the position of the small hole 13, the combustion gas from the small hole 13, which is formed in a convex shape around the hole, hits the convex section on the front side of the heat dissipation section 4 and is heated, thereby reducing the temperature unevenness of the heat dissipation section 4. This can be prevented, the entire heat radiating section 4 can be heated efficiently, and the amount of radiation from the heat radiating section 4 can be increased.

In addition, both ends of the partition plate 7 are bent to form bent portions, and the left bent portion 20 on the side of the outlet 6 is formed larger than the right bent portion 19 on the opposite side of the outlet 6, so that the large outlet is formed. The left bent portion 20 on the side makes it difficult to short-cut the combustion gas, and the right bent portion 19 on the opposite side of the outlet 6 is formed small, so that the combustion gas that has flowed to the opposite side of the outlet 6 is directed to the end of the partition plate 7. Since the heat radiates easily and flows toward the outlet 6, it is possible to prevent the occurrence of temperature unevenness in the heat radiator 4, efficiently heat the entire heat radiator 4, and increase the amount of radiation from the heat radiator 4.
